Description
Technical Field
[0001] This utility model relates to the technical field of diversion devices, specifically a diversion device suitable for self-flushing of siltation in long-distance water transport. Background Technology
[0002] Long-distance water conveyance diversion devices are engineering facilities used to control and guide the direction of water flow in long-distance water conveyance systems, optimize fluid dynamics performance, and ensure the safety and efficiency of water conveyance. Long-distance water conveyance diversion devices are auxiliary equipment specially designed for use in large-scale water conveyance systems (such as pipelines, tunnels, and canals). By adjusting the direction of water flow, they reduce energy loss, prevent siltation, and avoid water hammer effects, thereby ensuring the stability and safety of long-distance water conveyance.
[0003] Patent document CN220688355U discloses a long-distance water transmission pipeline device for preventing breakage. It discloses a device comprising a first pipeline and a second pipeline. The first pipeline has a fixedly connected retaining block inside, and a locking block is slidably connected inside the retaining block. A pressing rod is fixedly connected to the end of the locking block, and a spring is fixedly connected to the surface of the locking block. When this long-distance water transmission pipeline device needs to be disassembled and replaced due to aging or damage, the locking block is first slid inside the retaining block by squeezing the pressing rod. When the locking block is no longer inside the engagement port, the first and second pipelines are separated, completing the pipeline disassembly. Then, the locking block is slid into the retaining block by pressing the squeezing rod. Pressing the locking block again to align it with the engagement port and stopping the pressing allows the locking block to engage with the engagement port under the elastic force of the spring, completing the pipeline replacement and achieving the purpose of rapid pipeline disassembly and replacement.

The water supply plate is located on the inner wall of the guide pipe, and the high-pressure nozzles are installed on the outer wall of the water supply plate. A high-pressure water pump is installed at the top of the guide pipe. The screen is installed on the inner wall of the guide pipe, and an assembly block is installed on the outer wall of the screen.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model, by installing a self-flushing mechanism, avoids blockage in the diversion pipe. Existing diversion pipes often contain a large amount of gravel and debris in the flowing river water, which accumulates over time and affects the normal operation of the pipe. Therefore, this needs to be improved. The water supply plate is rectangular, and both the assembly screw and the assembly screw groove are treated with anti-corrosion. The high-pressure nozzles are made of tungsten carbide and coated with an alumina ceramic coating. Three sets of high-pressure nozzles are arranged on a single water supply plate. An interception net is installed at the inlet of the diversion pipe, and then the assembly screw is fixed to... In the assembly screw groove, and the guide pipe has a corresponding channel for matching the assembly screw, the assembly block is fixed inside the guide pipe. Then, the interception net is used to block the gravel and debris. When a large amount of debris accumulates in the interception net, the high-pressure water pump is connected to the external water source and the high-pressure water pump is connected to the external power supply. It is controlled by an external switch. Then, the high-pressure water pump supplies water to the water supply plate. Through the connecting pipe, multiple water supply plates can be supplied with water. Then, the high-pressure nozzle backwashes the impurities on the interception net to prevent the interception net from being blocked and affecting the normal water flow.
[0017] 2. This utility model protects the high-pressure nozzle by installing a protective mechanism. Existing high-pressure nozzles are positioned opposite to the water flow direction, causing them to be eroded by river water over time, leading to damage. Firstly, the material of the high-pressure nozzle is changed to tungsten carbide with an alumina ceramic coating, improving its wear resistance. When the high-pressure nozzle is not in use, the electric telescopic rod is connected to and controlled by an external power source. The electric telescopic rod then moves the protective plate downwards, with one end of the protective plate always penetrating the inside of the sealing ring. The protective plate then moves to one side of the front plate, sealing the spray trough. The protective plate is located at the front of the single-set water supply plate, thus protecting the high-pressure nozzle. Three sets of protective plates are provided. When the high-pressure nozzle needs to be used, the protective plates are moved upwards without blocking the spray trough, allowing the high-pressure nozzle to be used. Attached Figure Description

The flow guiding pipe 1 is fixed to the riverbed or the bottom of the channel through the anchor plate 2 at the bottom of the flow guiding pipe 1, thereby guiding the river water through the flow guiding pipe 1. The guide plate 19 is used to weaken the scouring force of the water flow on the bottom of the channel and protect the safety of the channel structure.
[0028] Please see Figure 2 and Figure 3 The inner wall of the diversion pipe 1 is equipped with a self-cleaning mechanism to prevent blockage. The self-cleaning mechanism includes a water supply plate 3, a high-pressure nozzle 4, and an intercepting net 7. The water supply plate 3 is located on the inner wall of the diversion pipe 1, and the high-pressure nozzle 4 is installed on the outer wall of the water supply plate 3. A high-pressure water pump 5 is installed at the top of the diversion pipe 1. The intercepting net 7 is installed on the inner wall of the diversion pipe 1, and an assembly block 6 is installed on the outer wall of the intercepting net 7. The outer wall of the assembly block 6 has an assembly screw groove 8, and an assembly screw 9 is installed on the outer wall of the diversion pipe 1, with one end of the assembly screw 9 extending into the assembly screw groove 8. A connecting pipe 10 is installed on the outer wall of the water supply plate 3. Currently, the river water flowing inside the diversion pipe 1 contains a large amount of gravel and debris, which accumulates in the diversion pipe 1 over time, affecting its normal operation. Therefore, improvements are needed. Three sets of water supply plates 3 are provided, and the water supply plates 3 are rectangular. The distance between the high-pressure nozzle 4 and the intercepting net 7 is... The interceptor net 7 has a diameter of 30mm and a height of 6cm. The assembly screw 9 and assembly screw groove 8 are both treated with anti-corrosion. The high-pressure nozzle 4 is made of tungsten carbide and coated with an alumina ceramic coating. Three sets of high-pressure nozzles 4 are arranged on a single water supply plate 3. The interceptor net 7 is installed at the inlet of the diversion pipe 1. Then the assembly screw 9 is fixed into the assembly screw groove 8. The diversion pipe 1 has a corresponding channel for matching the assembly screw 9. The assembly block 6 is fixed inside the diversion pipe 1. The interceptor net 7 is used to block gravel and debris. When a large amount of debris accumulates in the interceptor net 7, the high-pressure water pump 5 is connected to the external water source and the high-pressure water pump 5 is connected to the external power supply and controlled by an external switch. Then the high-pressure water pump 5 supplies water to the water supply plate 3. Through the connecting pipe 10, multiple water supply plates 3 can be supplied with water. The high-pressure nozzle 4 is used to backwash the impurities on the interceptor net 7 to prevent the interceptor net 7 from being blocked and affecting the normal water flow.
[0029] Please see Figure 4 and Figure 5The inner wall of the guide pipe 1 is equipped with a protective mechanism to protect the high-pressure nozzle 4. The protective mechanism includes a bracket 11, a protective cover 12, and a protective plate 14. The bracket 11 is located on the outer wall of the guide pipe 1, and the protective cover 12 is installed on the outer wall of the bracket 11. An electric telescopic rod 13 is installed on the inner wall of the protective cover 12, and the protective plate 14 is installed on the output end of the electric telescopic rod 13. The inner wall of the guide pipe 1 is provided with a fitting groove 15, and a sealing ring 16 is installed on the inner wall of the fitting groove 15. A front plate 17 is installed on the inner wall of the guide pipe 1, and a spray groove 18 is provided on the inner wall of the front plate 17. The existing high-pressure nozzle 4 is in the opposite direction to the water flow, so the river water washes over the high-pressure nozzle 4, which will cause damage over time. First, the high-pressure nozzle 4... By changing the material, the high-pressure nozzle 4 is made of tungsten carbide and coated with an alumina ceramic coating to improve its wear resistance. When the high-pressure nozzle 4 is not in use, the electric telescopic rod 13 is connected to and controlled by an external power source. The electric telescopic rod 13 then moves the protective plate 14 downwards. One end of the protective plate 14 always passes through the interior of the sealing ring 16. The protective plate 14 then moves to one side of the front plate 17, sealing the spray trough 18. The protective plate 14 is located at the front end of the single water supply plate 3, thus protecting the high-pressure nozzle 4. There are three sets of protective plates 14. When the high-pressure nozzle 4 needs to be used, the protective plates 14 are moved upwards without blocking the spray trough 18, allowing the high-pressure nozzle 4 to be used.
[0030] Working principle: The diversion pipe 1 is fixed to the riverbed or channel bottom by the anchor plate 2 at the bottom, thereby diverting river water. The guide plate 19 is used to weaken the scouring force of the water flow on the channel bottom and protect the safety of the channel structure. In the existing diversion pipe 1, the river water flowing inside is mixed with a large amount of gravel and debris, which will accumulate in the diversion pipe 1 over time and affect the normal operation of the diversion pipe 1. Therefore, this needs to be improved. There are 3 sets of water supply plates 3, and the water supply plates 3 are rectangular plates. The distance between the high-pressure nozzle 4 and the interception net 7 is 6cm, and the aperture of the interception net 7 is 3. 0mm, both the assembly screw 9 and the assembly screw groove 8 are treated with anti-corrosion. The high-pressure nozzle 4 is made of tungsten carbide and coated with an alumina ceramic coating. Three sets of high-pressure nozzles 4 are arranged on a single water supply plate 3. The interception net 7 is installed at the inlet of the diversion pipe 1. Then the assembly screw 9 is fixed into the assembly screw groove 8. The diversion pipe 1 has a corresponding channel for matching the assembly screw 9. The assembly block 6 is fixed inside the diversion pipe 1. The interception net 7 is used to block gravel and debris. When a large amount of debris accumulates in the interception net 7, the high-pressure water pump 5 is connected to the external water source. Water pump 5 is connected to an external power source and controlled by an external switch. High-pressure water pump 5 then supplies water to water supply plates 3. Through connecting pipe 10, multiple water supply plates 3 can be supplied with water. High-pressure nozzles 4 then backwash impurities on the interception net 7 to prevent blockage and ensure normal water flow. Currently, the high-pressure nozzles 4 are positioned opposite to the water flow direction, causing the river water to erode them, which can lead to damage over time. Therefore, the material of the high-pressure nozzles 4 is changed to tungsten carbide with an alumina ceramic coating to improve their wear resistance. If so, when the high-pressure nozzle 4 is not in use, the electric telescopic rod 13 is connected to and controlled by an external power source. Subsequently, the electric telescopic rod 13 operates to drive the protective plate 14 to move downward. One end of the protective plate 14 always passes through the interior of the sealing ring 16. Then, the protective plate 14 moves to one side of the front plate 17, thus sealing the spray trough 18. The protective plate 14 is located at the front end of the single water supply plate 3, thus protecting the high-pressure nozzle 4. There are three sets of protective plates 14. When the high-pressure nozzle 4 needs to be used, the protective plate 14 is moved upward without blocking the spray trough 18, so that the high-pressure nozzle 4 can be used.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
