The invention relates to hydraulic engineering and can be used for collecting water from the channels with turbulent flow.
Known water divider for channels with a large slope, including located between the inlet and transit channels trench side tailrace, the bars and the guide plate (shield drive) (USSR Author's certificate No. 351968, CL E02B 13/00, 1970).
The disadvantage of this device is that since the plate is inclined in the direction of transit of the canal, rolling her flow of water causes a vibration plate, which leads to disruption of the hydraulics of flow and splash water out of the channel. The unit cannot carry out the selection of flow vertically, stabilize consumption, exhaust, for example, in the fill, depending on the depth of immersion of the plate along the entire height of the filling channel with turbulent flow. Due to the installation of the lower end of the grid in horizontal guides in the gap between the lower end of the grate and the bottom of the channel can get drawn by the load, which may cause jamming of the grid, this leads to the partial termination of the water supply in the challenge. When changing the water in the channel is available in the stream long flexible fibrous items (stems of plants, algae and so on) stick to the rods of the grid and the plate, which creates a great effort to move lastine, and it leads to jamming, i.e., violation of the kinematics of turbulent flow leads to congestion pressure on the plate above the trench, the bandwidth is reduced; there is no possibility of cleaning the data elements directly in the turbulent flow, as they are submerged flow (velocity of water in the supply channel reaches 2 m/s and more). The cost of building large enough for air flow 1 m/s
Known also water divider for channels with a large slope, including inlet and outlet channels associated trench, located above the slot is rigidly fixed to the cutter. The bottom of the slot defined by the free-fall trajectory of the jet. Proper positioning of the cutter reached the fence the desired water flow in the outflow channels regardless of flow variations in the distribution channel. To achieve constant water drainage is based on the principle of dividing the flow vertically (USSR Author's certificate No. 120454, CL E02B 13/00, 1959).
In addition, modification of water divider - to simplify its design and avoid education cuts at the bottom of the distribution channel input end of the bypass pipe is made in the form of the tip of the cut lengthways and tapered metal tubes, placed immediately on the bottom of the distribution channel.
Because this device p. the moat version as difficult by design, as in the analogue, in pipes, buried under level located directly input end in the trench, having a large hydraulic resistance (energy loss of water), which dramatically reduces the consumption allocation and height, which requires a sufficient amount of water and the force of the hydrostatic pressure of the flow in motion. The cost of construction increases. In addition, siltation and hit random load when the divider channel off branches.
In respect of alterations to the water divider, as the closest prototype, there is the drawback is the location of the input end of the pipes, cut lengthwise and flattened metal pipes, laid directly on the bottom of the distribution channel. Due to the installation on the seabed off the exhaust pipe sediment silting up. In virtue of this profile shape and installed on the bottom of the channel is insufficient protection cap of the tube from the sediment; the inability to clean it flows with turbulent regime, which is in a submerged state. Stabilization of the exhaust flow is absent, because the depth of the water is constant, and does not take into account the mass of water pressure in the distribution channel, as described under paragraph 1 of the prototype. The shape and profile of the intake pipe laid end on d the f distribution channel does not allow the rapid flow, moving with great speed, to supply water to the sprinkler from different water levels in the distribution channel. In turn, the installation of the same diameter outlet pipe forms a helical movement along the length of the pipe, hence the large losses along the length of the narrow part of the tube, which significantly reduces water consumption and the possibility of formation of major congestion borne sediment. Therefore, the operational reliability is low.
The purpose of the invention is improving the reliability of the device by providing water from different levels.
This objective is achieved in that a device for collecting water from the flume channels with turbulent regime of flow, including the distribution channel, the input end of the pipe and the discharge pipe equipped with an integral segment of the pipe, forming a cone, made in the form of a shutter, mounted on Board tray hinge having a rotation mechanism in the form of a wheel with brakes.
In addition, the composite pipe segments comprise a radius of curvature on the axis of the cone Ro=1,25 dIwhere dIthe diameter of the entrance end of the pipe and the cone angle of the tip is equal to 6...9° to the bottom of the channel, while the output end of the cone is connected with a piece of pipe of constant cross-section with a flexible hose.
The execution of the discharge conduit of the separate handle the Cove pipes of different diameters, resulting in a diffuser in the form of a bolt that is installed with the possibility of wheel vertical movement of the hinge relative to the mounting Board tray allows you to use the structure of the turbulent flow (wave and bezosnovnogo) change the location of the shutter on the filling depth in the channel, providing a reliable operational performance of the building as a whole. This eliminates the need for the device to deep grooves for draining water to the sprinkler, and therefore the amount of work decreases. In addition, the diversion of water vertically to stabilize flow discharged into the fill, depending on the depth of water in turbulent flow. Slanting cut end at an angle 6...9° to the bottom of the channel and associated with the links (lines) tube diffuser, made in the form of a shutter with a radius of Ro=1,25 dIwhere dIthe diameter of the entrance end of the pipe, provide a helical movement of water along the length of the cone, the end of which is connected with a pipe of the same cross-section with a flexible hose, is omitted in the fill below the water level in the well. The surpluses are skipped together with carrying sediment and floating debris along the length of the distribution channel without damping the kinetic energy of the flow, and work facilities should be provided at a flow rate in CA is ale more than 2 m/s
In addition, new design construction allows you to explore the bolt without turning off the turbulent flow in the distribution channel, the shutter wheel goes over Board channel that improves the operational reliability of the device, eliminates shock impact of flow at the time of service of the diffuser in the form of a shutter. On the output end of the diffuser provides uniform movement with the incoming flow in the fill.
To increase the water enough to raise the free end of the flexible hose and, after filling with water the tribe of flexible hose pipe, put it in a decant of the fill, and the shutter works as a self-threading siphon. It also extends the range of water flow through a diffuser in the form of a shutter. Consumption of a device depends on the turbulent regime of flow and throughput speed may be of the form: Q=µώIV, where Q is the flow rate of the shutter (with losses); µ is the coefficient of discharge depends on kineticast flow; ώI- the area of the inlet end; V is the average water velocity in the channel. Hence, the device is a hydrometer. This approach to construction also reduces the load perceived by the mobile part of the working diffuser in the form of a shutter, and, accordingly, to reduce the dimensions of the structure.
Origin is lnost and simplicity above structure provides protection from sediment and floating debris in channels with turbulent regime of flow with sufficient accuracy the quality of water from different horizons in the channel as in the wave, and Bessonova modes. The path length of the flow in the diffuser is reduced, and thus the water flow rate can be increased with fewer losses at the local resistance along the length of the pipe. Screw the rotation of the fluid remains on the short section of the discharge pipe diffuser and is the most advanced in the cross-section at the end of the pipe, where the damping of the kinetic energy and the transition to potential energy in the flexible hose is lowered into the well fill. Under these conditions, at the end of the outlet section of the diffuser (gate) leads to the complete elimination of a misbehaving flow downstream, providing a uniform flow stream for flexible hose.
Based on the above, the author believes that it is possible to argue that the proposed solution meets the criterion of "Significant differences".
In Fig.1 shows a device for collecting water from the flume channels with turbulent regime of flow, in terms of Fig.2 - section a-a in Fig.1, in Fig.3 - section b-B in Fig.1.
The device consists of a composite pipe sections conic sections - diffuser made in the form of the shutter 1, has an input end of the pipe 2 and the pipe segment 3 a constant cross-section with a flexible hose 4. The shutter 1 is attached to the side of the channel 5 swivel with the steering wheel 6 (lever) with the stopper 7 in the form of limiter control. From DC water is in the distribution channel 5 head pipe 2 has an angle of taper cut within 6...9° to the bottom of the channel 5, and the radius of curvature on the axis of the cone 1 (shutter) is equal to Ro=1,25 dIwhere dIthe diameter of the entrance end of the pipe, i.e., the sizes are optimal. In the absence of water intake in the fill bolt 1 is moved to the upper position of the steering wheel 6 and is fixed by the stopper 7. This provides additional protection input tip from being hit by random transported sediment and floating debris in the distribution channel 5, as well as its inspection. The diameter of the cutting tube 3 is assigned on the basis of the output section of the pipe segment of the cone, which is connected with the input section of the head pipe 2, and is approximately Do=1,6 dIrounded to standard sizes manufactured pipes in the industry.
A device for collecting water from the flume channels with turbulent regime of flow is as follows.
The shutter 1 fixed onboard channel 5 hinge and is managed through a steering wheel 6, regulates the required inlet end of the pipe 2 on the planned stable water supply for tract distribution channel 5 with a flexible hose 4 in the fill. At this height position of the input end of the pipe 2 is specified position in the channel 5, which regulates a stable water supply to the sprinkler through a pipe 3 hose 4. At the same time the flow of water has longitudinal and transverse nestazionarnosty the Yu speeds flowing a head pipe 2 and the diffuser 1, does not create backwater speed thread and so compact moving stream without spouting.
In case of change of the filling in the channel 5 of the water, and changes in selected flow rate required through the mechanism of rotation in the form of a steering wheel 6 with the stopper 7, the shutter 1 to move according to the desired flow rate, while the flexible hose 4 is placed in the well of the fill, the end of which is submerged under the water level. It should be borne in mind that the sustainability of the shutter 1 are provided with a rational layout and technically competent design solution pipe diffuser, made in the form of the shutter, i.e., it is possible to call and scoop outlet. When flow in the head pipe 2 is the rotational movement of the flow approaching the extended part of the pipe segment 3 of constant cross-section, where the end portion is converted to potential energy, causing the intake flow in a flexible hose 4 for optimal water intake to fill the consumer.
With increasing water may be offered the option of use as a self-threading siphon. For this purpose it will be enough to lift the free end of the flexible hose and, after filling with water the tribe of fast hose - pipe, put it in a decant the PR is of sites to the consumer.
This interrelation and interdependence of the basic elements of the device ensures operational reliability and accuracy of the steady withdrawal of water from different levels in the distribution channel 5 and the optimal bandwidth in conditions of turbulent flow carrying sediment and floating debris.
Throughput through the gate (count of losses) can be determined from the formula: Q=µώIV, where Q is the flow rate passing through the shutter; µ is the coefficient of discharge of the gate depends on kineticast flow; ω is the square holes at the entrance to the diffuser; V is the average water velocity in the channel. It should be noted that the coefficient µ for turbulent flow (supercritical) regime is a rational function of flow rate (for a tranquil stream µ is the fractional irrational function of the depth of flow). This means that the device outlet is a hydrometer, which is enough on the stopper 7 limiter control to attach the scale, linking the raising and consumption.
Thus, the adoption of curvature of the diffuser, the degree of taper and a design flow of drainage water can be determined and the diameter of the intake tip of the cone, bearing in mind the velocity of flow through the channel.
The effectiveness of the proposed device is that p is the changes it can significantly increase the capacity of channels with turbulent regime of flow taking into account the requirements of the building height of the channel. The construction of reliable and economical in operation, as the allotment of fully protected from siltation and clogging. The shutter device of this form and type, fixed hinge onboard channel, will allow you to make the switch to a remote control, in addition, does not require the reconstruction of a section of the channel and can be built at any time without interruption of the water supply channel.
