[0023] The guide channel 1 can be set at the outlet of the water conservancy project, and an interception rod 2 is fixedly connected to the inner wall of the guide channel 1. The interception rod 2 is set on one side of the interception surface of the interception net 3. By setting the interception rod 2 on one side of the interception net 3, large impurities in the water flow, such as tree branches, large plastic bags, etc., can be effectively captured to prevent these impurities from entering the guide channel 1 with the water flow and causing blockage of the interception net 3.

[0024] During the operation of the guide channel 1, a support frame 4 is provided on the guide channel 1, and a lift gate 5 which can be raised or lowered is provided on the support frame 4 to control the water speed or flow of the guide channel 1. A driving device for driving the lift gate 5 to be raised or lowered is provided on the support frame 4. The driving device can be a lifting hydraulic cylinder or a motor to drive the lift gate 5 to move.

[0025] By controlling the gap distance between the lifting gate 5 and the guide channel 1, the water flow rate can be adjusted. The water flow will first be intercepted by the interception rod 2 to intercept large impurities in the water. When the water flow passes through the interception net 3, the interception net 3 will intercept other impurities in the water and attach them to the interception surface of the interception net 3.

[0026] By driving the cleaning mechanism to move back and forth on the fixed box 7 through the movable block 9, the cleaning end of the cleaning mechanism can be moved in contact with the interception surface of the interception net 3 to scrape the attached impurities on the interception net 3.

[0027] Furthermore, in order to improve the cleaning efficiency of the interception net 3, the above-mentioned cleaning mechanism includes a scraper 10 fixedly connected to the movable block 9, the end of the scraper 10 is in contact with the interception surface of the interception net 3, the scraper 10 is fixedly connected to an extension plate, the extension plate is rotatably connected to a rotating shaft 12, a cleaning roller 13 is fixedly connected to the rotating shaft 12, and a cleaning brush 14 is provided on the outer wall of the cleaning roller 13.

[0028] The rotating shaft 12 extends to the outside of the extension plate and is fixedly connected to a transmission gear 15 . The top of the fixed box 7 is fixedly connected to a rack 18 , which meshes with the transmission gear 15 .

[0029] When the movable block 9 drives the scraper 10 to move, the end of the scraper 10 fits against the intercepting surface of the intercepting net 3 to scrape and sweep the impurities attached to the intercepting net 3. During this process, the rotating shaft 12 is affected by the rack 18 to drive the transmission gear 15 to rotate, so that the transmission gear 15 drives the cleaning roller 13 to rotate, and then the cleaning roller 13 drives the cleaning brush 14 to rotate and brush the impurities on the intercepting net 3, thereby reducing the accumulation of impurities on the intercepting net 3 and keeping the intercepting net 3 unobstructed.

[0030] When the scraper 10 is in operation, the output end of the backwash mechanism flushes toward the water outlet surface of the interception net 3, which can effectively flush away impurities and sediments attached to the interception net 3 and reduce the accumulation of impurities.

[0031] Furthermore, the backwashing mechanism includes a backwashing box 36 fixedly connected to the movable block 9 , and a backwashing hole 37 is provided on the backwashing box 36 , and an output end of the backwashing hole 37 faces the water outlet surface of the interception net 3 .

[0033] When the switch of the water pump 20 is turned on, the input end of the water pump 20 will pressurize the filtered water source in the channel of the guide channel 1 and transport it to the diversion box 24 through the delivery pipe, and then transport it to the backwash box 36 through the first connecting pipe 25, and then spray water from the backwash hole 37.

[0034] A toggle plate 11 is fixedly connected to the scraper 10, and a water spray box 16 is fixedly connected to the side wall of the toggle plate 11. A water spray hole 17 is opened on the water spray box 16, and the water spray end of the water spray hole 17 faces the cleaning chute 30, and the water spray box 16 is connected to the diversion box 24 through a second connecting pipe 27.

[0035] When the scraper 10 moves, the toggle plate 11 can be used to toggle the impurities in the water source toward the cleaning chute 30, and the water spray box 16 will also spray water in the direction of the cleaning chute 30, so that the water flow can drive the impurities to move to the vicinity of the cleaning chute 30, so that the impurities in the water are quickly guided into the cleaning chute 30, thereby improving the efficiency of cleaning impurities in the water.

[0036] When impurities move into the cleaning chute 30, the lifting and lowering support plate mechanism can drive the impurities to move upward, so that the impurities move through the gap into the collection box 6. A filter is provided in the collection box 6 to centrally intercept the impurities.

[0037] Moreover, when the impurities are moving, the crushing end of the guiding crushing mechanism will crush the impurities. On the one hand, it can crush the large impurities and reduce the phenomenon of impurity blockage. On the other hand, it can also quickly collect the crushed impurities.

[0039] When the movable block 9 moves to one side of the booster cylinder 34, the movable block 9 abuts against the contact plate on the booster rod 35. At this time, the booster rod 35 drives the sealing plug to move, and the cavity on one side of the sealing plug will generate negative pressure, so that the gas in the guide cylinder 31 is transported to the cavity on one side of the sealing plug through the pipeline, and then the booster rod 35 drives the guide support plate 33 to move from the bottom of the cleaning chute 30 to the top, and a plurality of through holes are provided on the guide support plate 33 to prevent the water flow from causing fluctuations to the impurities, and move the impurities at the bottom upward to the crushing end of the guide crushing mechanism, and then crush them and then transport them to the collection box 6 through the gap.

[0040] During this process, the gas in the cavity on the other side of the sealing plug will be transported to the first connecting pipe 25 through the air outlet pipe 26, and then the first connecting pipe 25 will be pressurized to mix the air with the water delivered by the water pump 20. When bubbles are formed in the water, a large amount of energy will be released, which can cooperate with the backwash box 36 to backwash the impurities on the surface of the interception net 3, and when the bubbles are broken, micro water flow and impact force will be generated, which can help the impurities adhering to the interception net 3 to fall off more easily, thereby improving the cleaning efficiency.

When the transmission shaft 22 rotates, it will drive the connecting shaft 28 to rotate through the driving pulley, and then the connecting shaft 28 drives the crushing knife 29 to rotate. During the rotation, a vortex may be formed at the cleaning chute 30, and then the reciprocating toggle plate 11 will push the crushed impurities to the notch, and then the impurities will be filtered and collected by the collection box 6, and the filtered water source will be re-delivered to the guide channel 1.
