Traditional navigation locks and dams are one of the types of regulation of water flow, making it easy to control the flood waters of the river and navigation on it in two ways: 1) control the volume of water in the river and thereby regulation of pools formed above and below the dam, with the purpose of providing flood protection and sufficient for navigation depth of the channel and 2) determining the number of cycles of locking and selection of water level between the gate gateways when lifting or lowering the vessel, passing the gateway and the dam.
The present invention features designed to create the of hybrid hydropower installation frame, uniting a group of interconnected hydropower turbo-generators and uses the potential energy of the "head" (or difference between the vertical water level), provided the existing water dam. By adding to the traditional gate of the new frame(s), including innovative hydropower turbine system, the existing flood-control dam and the gateway into the hydropower installation. This rotary frame may also find application in various places, including the dam, raising the level of reservoirs, canals, aqueducts, sewage of industrial enterprises and other areas where there is backed water. The gateway module frame can also be used in the shipping gateway by adding equipment for lifting and lowering it or opening it through one or more hinge elements. In this arrangement, it can effectively replace sluice gates. Can also be used floating caisson (hull), enter the gateway or the output of the gateway to provide navigation.
In a typical shipping gateway has two sets of gates, commonly called the upper and lower gates. Every gates usually consist of two halves (in some cases you only use one door); with wings closed, they top the t entire channel gateway. The design proposed in accordance with the preferred implementation of the present invention, provides that a group of large, modular, interconnected and interchangeable turbine is installed in a movable frame, which may replace one or more of the valves in shipping gateway, with each turbine is connected with its own generator. In a preferred embodiment, the frame may contain two or more turbines.

In addition to secure gateway module frame needs some pile design and pile attachments can be completely recessed below the expected levels of navigation. So must be provided by a pre-set minimum pile construction, designed for mounting the gateway framework in place Pile construction are described in more detail hereinafter in connection with Fig.6.
In Fig.2 presents a blank module 40 gateway frame with crane device 42 for loading modules in the cell made with the possibility of installing the turbine frame module 44, the separator module or modules 46 and generator module 48. The stacked modules, shown below in figures 7A and 7B, going into the unit, which is assigned the reference symbol 43. When mounting stability Shluzovaya the frame 40 can attach struts 50. Crane device 42 is located above the main gateway module frame to facilitate mounting of various proposed in the present invention the component. Crane device is located with the possibility of placing the individual modules in several different locations 52, of which are denoted by the corresponding three positions. As further shown in Fig.3, each module can be installed at the top, above the water level. Each of these to the ponent - turbine, the separator and the generator can be lowered into position in the frame or at the gate using a gantry crane, bridge crane or other rotary valve acting on the entire length of the frame.
In Fig.3 shows a partially completed rotary frame 60 with a group of generators 63, already installed in a working position. Crane device 42 moves the frame generator module 62 along the longitudinal axis of the crane device and places the selected equipment over its position in the frame for mounting. As an example, the generator module 62 is loaded with floating bases 90 (shown in Fig.5) and rises to a height of crane device 42 to move along the longitudinal axis of the device in the desired position. In Fig.3 shows the frame generator module 62 with the collected generator 64, a floating crane for installation in the operating position. Similarly turbine frame module 68 has been moved to a certain position and lowered into the corresponding aperture. In some embodiments, may be used rolling shutter 66 (Sandora beam) to pass the selected water flow at a particular turbine, in this example, the turbine frame module 68. Rolling shutter 66 may operate mechanical or pneumatic / Hydra is symbolic mechanism, widely known in the prior art, and it can be done with damping for easier opening and closing of the shutter. Rolling shutter can also have a streamlined configuration with one edge to facilitate flow around the stopper and the best damping in the process of moving. Crane device 42 may be configured as a separate module that can be installed on the frame 60 on the mounting area near or at the initial stages of installation. This option primarily provides improved logistics, when the transport device along the river to pass under constructions limited height (low bridges, power cable trays, and so on).
In Fig.4 shows balastiera floating caisson structure 80 shown schematically embedded modules 86 gateway frame above the floating compartments 82, 84 and 85. Main ballast tank 85 provides buoyancy, withstanding the load, which are built of frame modules 86. Differentia tanks 82 and 84 can be used to further adjust the buoyancy. In the lower part of the caisson floating structure 80 is concrete ballast tank 88, ensuring stabilization and additional stability. Coffered Konstrukcija can be any of a variety of ship designs, related to ship hulls, etc., It is designed to serve alastruey marine corps for the transportation and installation of the gateway module frame according to a preferred variant implementation of the invention. The configuration and arrangement of such caissons are widely known in the prior art and need no detailed description. However, none of the mobile and remove the hydropower system of ship transit case in prior art not disclosed. There are many ways of carrying out the invention it may be desirable to install the gateway module frame to a more robust design, not not strictly fixed or floating vessel body described above. However, in some configurations, the gateway module frame is preferably mounted on a floating structure that is easier to send to some place with a tug or ship the vehicle.
In Fig.5 shown mounted rotary frame 60 mounted near the valves 26 and used for energy production due to the drop in water level at the gateway. Lock gates 26 should be opened to allow water to pass through a lock frame 60 to generate energy. Near crane 42 posted by barge 90, providing docking gantry crane, for example,with frame generator module 62 or turbine frame module 68. After selecting intended for installation of the module crane device 42 moves the module from a barge 90 to the corresponding height of the rack frame 60 and then over the position in shluzova frame, which holds the selected module. Barge 90 and the valve 42 can also be used for maintenance, remove the installed modules and installation of replacement. Each of the generator, the separator and (or) turbine frame modules can be easily moved to its position in the row-generating cells, formed by a combination of generators and turbines. As described in more detail below, the generator and turbine in each energogeneriruyuschey cell interconnected, producing the energy due to the motion of the turbine. In the private embodiment shown in Fig.5, there are nine combinations generator/turbine. When the parallel use of several sections there is no need for the sluice gate, as the configuration with multiple partitions reduces the flow in small steps (in the case of nine sections, shown in the figures, the flow can be adjusted with a drop of 11.1% by overlapping individual turbines). Thus the individual components in combination turbine/generator are modular, removable and interchangeable in several predefined configurations. It also provides variative the ity of the vertical dimension of the combination of the turbine, generator and separator by changing the size of the separator and the total height of the lock frame module. Under certain conditions, the system configuration can be changed to alternative spillway by ensuring the passage of water through the gate and then through the turbine channels, even if there is no electricity. Accordingly, the system creates an adjustable spillway, which previously did not exist.
In Fig.6 provides a side view of the module 100 rotary frame having a turbine 102 located to receive water through the penstock 116, which may be of welded construction or design of precast concrete, such as the outlet of the dam. The water upstream of the gateway module frame has the potential pressure due to the rise of the surface 115 and creates energy when the flow in the lower reach through pressure conduit 116, the turbine 102 and the discharge pipe 114, which may also be welded or precast concrete. Turbine 102 operable connected to the generator 106 chain transmission 105, driven by externally rotating outer rim 118 of the turbine, performed together with the hub of the impeller of the turbine and driving the intermediate shaft (transmission shaft) 117, which is a chain or belt drive 104 is connected to the generator 106. Taka the system also acts as a multiplier. Preferably the turbine 102 are stationary impellers ship type without guide vanes or blades with adjustable slope. It is easy to see that the mechanical drive connection between the turbine and the generator do not require lubrication, as they are below the water level, and, consequently, the shaft bearings can be water-lubricating. This design is safe for the environment and provides simplified maintenance mechanically movable parts.
Alternative power with turbine 102 through the outer rim 118 of the turbine can be transmitted to the generator via the pinion gear and drive shaft (not shown), directly or indirectly connected to the generator 106 through another gear. In this embodiment, the power is transmitted from the rotating outer rim of the turbine without the need for intermediate belt or chain, which in some circumstances can provide the preferred results. The system direct drive pinion and shaft in a closed modular system that uses the above-described technology has potential advantages in large power plants or at high speeds.
The module 100 gateway frame is mounted on a pile of nozzles 124 below 107 muddy sediment and placed on sway, clogged installed in advance or otherwise introduced into the ground 112. Pile nozzle 124 is completely buried their ends below the levels of navigation. Alternative gateways with structural plates that can withstand the weight of the module structure of the gateway frame, the gateway module frame can be directly placed on the structural elements with the distribution of the load over a larger area, which eliminates the need penetration in existing subsurface structures and soil.

Are presented in figures 7A and 7B embodiment, the energy is transferred from the turbine 102 through a chain or a belt drive 104 without an intermediate belt or shaft. In these figures shows an alternative configuration of the drive that does not use the intermediate shaft. These figures also shows the use of two separation modules, the smaller of which is located on a large. Turbine 102 shown in working condition connected with generator 106 installed in the generator frame mo is ule 110. For simplicity, the image dividing module 120 shown only in Fig.7B, but it is located preferably above the turbine 102 and below the frame generator module 110. A dividing module 120, partially shown in Fig.7B is a structural node, which can be lowered to a specific location in the gateway module frame and which is arranged to compliance with requirements, provide certain height on the mounting platform. Also shown is an auxiliary separator module 121, the presence of which in certain configurations, it is desirable to further separate the generator and turbine units with a higher working pressure. Entire vertical Assembly equipment or power modules including a turbine 102, intermediate drive chain drive 104, a dividing module 120 and generator module 110 may be removed from the module rack frame and replaced in less than a day. As described in more detail above, various components of an individual combination of generator and turbine can be omitted gantry crane mounted at the top of the gateway module frame, and installed in its location in the row of turbines/generators. In some embodiments, the execution may be present turbine and is coupled with the generator, separated by the delimiter variable is the size, which can be jointly inserted into the receiving openings in the gate. Thus, the individual components in combination turbine/generator are modular, removable and interchangeable on several predetermined positions. It also provides the variability of the vertical dimension of the combination of turbine, generator and separator by changing the size of the separator, adjust the height of the head in a specific location. In a preferred embodiment of the generators can be generators of low cost, commercially supplied by the original equipment manufacturer (induction, direct current, alternating current, synchronous, permanent magnet, and so on), which are primarily used in new systems, currently driven wind turbines and other means. In addition, there is no need for a gear box in the application of a simple chain and belt drive system, which provides increased speed when using solutions that replace on the spot, simple control and maintenance.
In figures 8A, 8B and 8D shows an empty frame generator module 110 in perspective, a front view and a cross section along a-a from Fig.8B, respectively.

In the lower part of the separation module 120 are receiving apertures or recesses (not shown) that are used to mate with the pins 146, shown in Fig.8A. Each turbine, generator and separator module is receiving apertures or recesses serving to mate. A dividing module 120 may be of any height to accommodate a particular desired configuration, or may be a vertical set of several separation modules. In Fig.10A Dan turbine cascade module 102 with partially shows an input channel of the turbine. In Fig.10B schematically depicts a converging inlet 135 and diverging output channel (breather pipe) 130. As described earlier in connection with Fig.6, the rotating outer rim 118 is placed between the two channels, both the providing at rotation interaction turbine with a drive chain or belt transmission via large drive wheel and thus the interaction with the generator.
