The invention relates to the field of hydropower, and more specifically to devices, transforming the river into electrical energy for the needs of a particular consumer (hydroelectric dam), and can be used for stand-alone lighting of large and medium bridges.

The prior art devices that convert the energy of the river flow into electrical energy, which is used to power the light source. Built hydropower plant for lighting river navigation buoy in the patent RU 2147285, IPC B63B 22/16, publ. 10.04.2000, is intended to refer to the navigation path and includes a turbine with a vertical shaft, a flexible transmission connected to the shaft of the generator. Hydraulic installation installed on the float, which is the Central element of the buoy. The turbine is located in the truss in the underwater part of the buoy and the generator housed in a waterproof camera, which is mounted inside the signal shape, located in the surface part of the buoy. To protect the turbine from debris along the bottom edge of the float is installed mouserotate flap. Because hydropower plant is made with a vertical shaft, there are energy losses due to overcoming the flow resistance of the turbine blade. Therefore, efficiency is Yunosti use the energy of the river flow, hence, the efficiency of the installation are reduced.

Closest to the claimed as the invention of the system of Autonomous sanctification is a micro hydropower plant (micro hydro) power of the signal light source river navigation buoy in the patent RU 2241631, IPC B63B 22/16, F03B 13/10, publ. 20.08.2003. Hydropower plant (micro hydro) at the specified patent is made with a horizontal shaft and mounted on the float catamaran base type. Hydropower plant contains interconnected hydro site, a generator and a control device, a source of signal light. The device control signal source of light connected with the signal light source. Hydraulic unit (blade Assembly) consists of two turbines, mounted on both sides of the generator on its shaft and is displaced by an angle of rotation relative to each other by half the angular spacing of the blades. The shaft of the generator, which is also the shaft of the turbines, is located horizontally across the flow over its surface to ensure interaction of the blades of the turbines with flow below the axis of rotation of this shaft. The generator and the device control signal source of light housed in a waterproof camera, which is the case of hydropower mouth is ovci. The diameter exceeds the diameter of the turbines. To protect the blades of the turbines from debris floating on the surface of the water, there mouserotate shield in the form of a canopy, made on the float buoy. Efficiency of the hydropower plant on the prototype of the higher efficiency of the previous version.

The disadvantage of the invention of the prototype is a low power device for the external lighting of the bridge as: hydropower plant is located in the free stream, which is characterized by low velocity and has a small area of impact of the flow on the blades of the turbines. Other disadvantages include the inconvenience of maintenance and installation.

The objective of the invention is using the river, without the involvement of external energy, to provide a robust, stand-alone lighting of the bridge, and convenient Assembly and maintenance of the lighting system.

The technical result that allows to solve the problem is to increase the efficiency of the lighting system due to the significant increase of the flow velocity of the river water around the prop and increase the shaft speed of the generator.

The problem is solved as follows.

The system of Autonomous lighting of the bridge, as the prototype contains connected to the light source hydropower installation. Hydropower installation the spacecraft consists of a blade unit and generator, connected by a single shaft. The shaft is positioned horizontally to ensure interaction of the blades of the blade Assembly with the river water flow. As a prototype, the system contains mouserotate the flap.

Unlike the prototype according to the invention hydropower plant is placed under water and further comprises a planetary gear, mounted on a single shaft between the blade Assembly and the generator, the shaft is located along the river of the water flow. A blade Assembly is made in the form of jet screw. Screw, planetary multiplier and generator housed in a single housing with extended inlet and outlet ports. The difference is that mouserotate flap is made in the form of a lattice and installed before you screw in the inlet bore of the housing. In addition, the hydropower plant is fixed on a support bridge on the guides with the possibility of vertical movement and fixation. The system of Autonomous lighting of the bridge further comprises a frequency Converter voltage, connected to a generator and light source, and a battery connected to the frequency Converter voltage. In addition, the system is equipped with a winch connected to the casing of the hydraulic installation. The frequency Converter voltage, the battery and winch set the go at the mounting site, which is additionally mounted in the upper part of the bridge supports.

Guides hydropower installation can be made in the form of channel bars mounted on the support bridge and the building of the hydropower plant installed in the guide rails by means of rollers. For fixing the position of the hydropower plant on the support bridge made stops. To enhance the power system it may optionally contain one or more hydropower plants, mounted on a support height on some rails and rigidly interconnected, with a winch connected to the upper body of the hydropower plant.

The task of the Autonomous lighting is solved using the hydropower plant, consisting of a generator, a planetary multiplier and axial jet screw. The screw affects the flow of water, causing it to rotate transmitted through the shaft to the planetary multiplier, which increases the rotational speed of the generator. The housing has an enlarged inlet and mouserotate grille that protects the screw from the impact of foreign objects under water. Case with rollers and guide bars attached to the support bridge that allows lifting the body of the winch on the mounting platform for Smotri repair. The low frequency current from the generator is supplied to the frequency Converter voltage to bring and further use of standard consumers of the light source. Surplus electricity, for example in the daytime, go next to the battery, which, if the failure or repair of the hydropower plant will support Autonomous lighting.

Placement of hydropower plants on the support allows you to:

1. To develop more power, and thus to increase the efficiency, in comparison with the prototype, due to a significant increase in flow rate when the flow of support and increase the shaft speed of the generator.

2. To provide raising and lowering of the turbine to the desired depth at the established guides on the support.

3. By the device of the mounting platform on a support to maintain and repair the hydropower installation without dismantling the entire machine.

The invention is illustrated by the drawing, which schematically presents the system of Autonomous lighting of the bridge.

Hydropower plant comprises a screw 1 and the generator 2 are interconnected by means of a single shaft 3 and is connected to the planetary multiplier 4 serving to increase the rotational speed of the generator 2.

The housing 5 of the hydropower plant has an extended input open the e to increase the impact of the water flow and enlarged the hole for the free flow of water. At the entrance installed macaronesia grating 6, which protects the screw 1 from the impact of foreign objects under the water.

The housing 5 mounted on a support axle 7, in the zone of compression of the water flow due to a significant increase in the flow rate when the flow of support. With the rollers 8 and the guide channels 9 and winch 10 is lifting the body 5 on the mounting pad 11 for inspection and repair.

The housing 5 in the winter period is set at the same distance from the bottom of the river and the bottom of the ice cover. Depth of body 5 is fixed by the stop 12, located in the lower part of the support. The location of the device between the bottom and the bottom surface of the ice will ensure its use at any time of the year.

With the generator 2 is connected to the frequency Converter voltage 13 for stabilizing the operating frequency of the electrical equipment. With the Converter 13 is connected to the battery 14. With a frequency Converter voltage 13 is connected to the light source (not shown). Light source M.B. any lamp for artificial lighting of the bridge.

The capacity of the hydropower plant can vary depending on the diameter of the jet screws, and the lighting of the bridge - from the number of locations of the proposed systems on the supports. Depending on the length of the bridge and the amount consumed is about electricity hydropower plant may be placed on two sides of a support and on several supports, and depending on the depth of the river it is possible to arrange several hydropower plants in height (not shown).

The system of Autonomous lighting bridge operates as follows. The flow of water at the meeting with the support of a bridge around a support, in this case, as it is known (Fedotov GA Survey and design of bridges: textbook. book for students. the Supreme. the textbook. Institutions. / Gaidarov. - M.: Publishing center "Academy", 2005. - 304 S.) the rate of flow of water the bearing is greatly increased. Acting on the jet screw 1, the flow of water with considerable speed, causes the screw 1 to rotate. This macaronesia grating 6 protects the screw from foreign objects. Rotation of the screw 1 is transmitted via the shaft 3 through the planetary multiplier 4 to the generator 2, the output of which produces electricity. Using planetary multiplier shaft speed of the generator increases. To stabilize and regulate voltage frequency is a frequency Converter voltage 13, from which the cable power is transferred to the light source. In the daytime the electricity stored in the battery 14 for use of electricity in the repair of the hydropower plant. In the event of a malfunction or for the purpose of inspection hydroenergy the political setting using the winch 10 along the guide rails 9 rises to the mounting area 11, where is the repair and subsequent lowered to the operating position. When two vertically arranged and fixed between the hydropower plants on the water surface rise both installations at the same time.

Thus, the invention allows:

1. To ensure coverage of the bridge due to the use of the hydropower plant, mounted on a support (s) of the bridge.

2. To increase the capacity of the hydropower plant, mounted on a support in a compressed section of the flow of water, compared to located in the free stream of the prototype.
