[0002] A gate is a control facility used to close and open a water discharge channel. The patent with the application number 202111494809.0 discloses a highly sealed intelligent measurement and control aluminum alloy gate, including a gate. Sliding grooves are provided on both sides of the gate. A gate plate is slidably installed on the inner side wall of the sliding groove. A screw-type hoist is installed on the inner side wall of the gate. The output end of the screw-type hoist is fixedly connected to the gate plate. A hollow sleeve is fixedly connected to the upper surface of the gate. A support frame is fixedly connected to the end of the hollow sleeve. A solar panel is installed at one end of the support frame. A piston cylinder is fixedly connected to the inner side wall of the gate. A pumping tank is communicated with the bottom of the piston cylinder. When the gate plate rises, the pumping work is completed through the cooperation of the piston cylinder and the pumping tank. When it descends, water is discharged into the water supply chamber, and the sand and gravel on both sides of the gate are impacted through the drain holes, achieving the purpose of protecting the gate and improving the sealing effect. However, it can only flush water out through the drain holes during the descending process of the gate plate, and will not flush water out through the drain holes during the ascending process of the gate plate, resulting in low efficiency.

[0023] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in conjunction with the drawings of the present invention.

[0024] Detailed implementation manners: In conjunction with Figures 1 - 10As shown in the figure, a gate capable of cleaning sediment at the bottom includes a gate frame 2 and a gate panel 1. Sealing rubbers are arranged on the left, right and lower parts of the front side of the gate panel 1. The bottom of the gate frame 2 is a bottom plate 22. Slide grooves 23 are arranged on both the left and right sides of the gate frame 2. The left and right sides of the gate panel 1 are located in the slide grooves 23. A notch 231 is arranged at the upper part of the slide groove 23. Driving plates 12 are arranged on both the left and right sides of the top of the gate panel 1. A beam plate 21 is arranged on the front side of the bottom plate 22, and a water spraying device 3 is arranged on the rear side. Interlayers 24 are arranged on the outer sides of the two slide grooves 23 of the gate frame 2. The bottom of the interlayer 24 is closed, and water cannot enter the interlayer 24 from the bottom. The driving plate 12 passes through the notch 231 and extends into the interlayer 24. When the gate is completely closed, the lower end of the notch 231 is slightly lower than the bottom surface of the driving plate 12. A first sprocket 4 and a second sprocket 5 are respectively rotatably connected to the front and rear sides of the upper part of the interlayer 24, and a third sprocket 6 and a rotating shaft 7 are respectively rotatably connected to the front and rear sides of the lower part of the interlayer 24. The second sprocket 5 is directly above the rotating shaft 7 and their axes are on the same vertical plane. The first sprocket 4 is directly above the third sprocket 6 and their axes are on the same vertical plane. Second gears 72 and sprocket type one-way clutches 71 (the structural principle is the same as that of the freewheel on a bicycle. In fact, the freewheel on a bicycle is a sprocket type one-way clutch of a certain specification. When the specification size is appropriate, the freewheel on a bicycle can also be directly used. Since it is a mature product, the detailed structure will not be introduced) are arranged on the two rotating shafts 7. The locking clockwise directions of the two sprocket type one-way clutches 71 are the same. The chain 14 sequentially bypasses the three sprockets and a one-way clutch 71, and then its two ends are respectively connected to the upper and lower sides of the driving plate 12. The two ends of the left and right chains 14 are respectively located at the front side of the first sprocket 4 (as shown in Figure 6 as shown in) and the rear side of the second sprocket 5 (as shown in Figure 8As shown in [Figure], the part of the chain 14 in front of the first sprocket 4 is in a vertical state and on the same straight line, and the part of the chain 14 behind the second sprocket 5 is in a vertical state and on the same straight line. The two second gears 72 are respectively engaged with the first gears 332 on the left and right sides of the water spraying device 3 to drive the water spraying device 3 to spray water onto the beam plate 21 along the bottom plate 22. During use, the rear side of the gate of the present application faces the side with high water level, and the gate plate 1 is connected to the hoist arranged above the gate. The hoist can drive the gate plate 1 to lift and lower. When the gate is opened, water flows from the rear side of the gate to the front side. Due to the blocking effect of the beam plate 21 (which is used to cooperate with the water stop rubber at the lower part of the front side of the gate plate 1 to achieve the sealing of the lower part of the gate), sediment is likely to accumulate on the rear side of the beam plate 21 (when there is a large amount of sediment deposited here, it will be difficult for the gate plate 1 to fall in place, resulting in poor sealing of the lower part of the gate and water leakage). When the gate plate 1 descends to close the gate, the driving plate 12 will drive the outer race of the one-way clutch 71 to rotate through the chain 14. Since the two ends of the chain 14 on the left and right sides are respectively located in front of the first sprocket 4 and behind the second sprocket 5, the clockwise directions of the rotations of the outer races of the two one-way clutches 71 are opposite. The inner race of one of the one-way clutches 71 rotates with the outer race to drive the shaft 7 and the second gear 72 on this side to rotate (while the inner race of the other one-way clutch 71 does not rotate with the outer race). The second gear 72 drives the first gear 332 to rotate so that the water spraying device 3 sprays water (the water speed should be relatively fast, and the number of teeth of the second gear 72 is multiple times that of the first gear 332). The sprayed water flows along the bottom plate 22 and will flow upward after reaching the beam plate 21 (washing away part of the sediment deposited on the bottom plate 22 during this process) and is carried forward by the water flow flowing through the gate normally (at this time, the gate has not been completely closed). If it is considered that there is a large amount of sediment deposited on the bottom plate 22, the gate plate 1 can be lifted and lowered several times repeatedly. During the ascending process of the gate plate 1, the inner race of the other one-way clutch 71 rotates with the outer race to drive the corresponding shaft 7 and the second gear 72 to rotate. The second gear 72 drives the first gear 332 to rotate so that the water spraying device 3 sprays water, so that the water spraying device 3 can be driven to spray water both during the ascending and descending processes of the gate plate 1, and the cleaning efficiency is relatively high.

[0025] Specifically, the water spray device 3 has a cylindrical cavity running through its left and right sides, and water inlets 311 are respectively provided on the left and right sides of the cavity. A filter can be provided at the water inlet 311 to block larger debris. The water spray device 3 is provided with a slit 32 connected to the cavity on the side facing the bottom plate 22. Preferably, the lower end of the slit 32 is flush with the upper surface of the bottom plate 22, and the top of the water spray device 3 is as low as possible to reduce the obstruction to the water flow through the gate. The two ends of the central axis 33 in the water spray device 3 respectively extend into the interlayer 24 on both sides and are rotatably sealed and connected to the inner side of the interlayer 24. The first gear 332 is provided at the end of the central axis 33 and is located in the interlayer 24. The central axis 33 is provided with impellers 331 at the inner sides of the two water inlets 311, which spray water in the direction of the middle of the central axis 33 at the same time. When the central shaft 33 rotates in the set clockwise direction, the impellers 331 on both sides drive water to flow into the cylindrical cavity and spray out from the slit 32. The set clockwise direction is the rotation direction of the central shaft 33 required for the water to spray out from the slit 32. The central shaft 33 rotates in the set clockwise direction when the gate plate 1 rises and falls. Due to the linkage effect of the central shaft 33, when the inner race on one one-way clutch 71 rotates with the outer race, the inner race and the outer race on the other one-way clutch 71 rotate relative to each other during the lifting and lowering process of the gate plate 1.

[0026] Furthermore, vertical pipes 31 are provided on both sides of the water spray device 3 , and the water inlet 311 is located at the top of the vertical pipe 31 , so that the sediment content at the location of the water inlet 311 is less.

[0027] Further, a push plate is provided on both sides of the middle of the rear side of the gate plate 1, and the rear side of the push plate gradually tilts forward from top to bottom. A wedge plate is provided on both sides of the rear side of the gate frame 2, and the front side of the wedge plate gradually tilts forward from top to bottom. When the push plate contacts the wedge plate, the gate plate 1 is pushed forward while falling, so that the water-stop rubber on it presses the front side of the slide groove 23. In this case, a slider 13 is slidably connected to the driving plate 12, and the slider 13 passes through the upper and lower sides of the driving plate 12. The two ends of the chain 14 are respectively connected to the upper and lower sides of the slider 13. When the gate plate 1 moves forward and backward, the slider 13 will slide forward and backward relative to the driving plate 12. Specifically, a long hole 121 is provided on the driving plate 12, and the slider 13 is in an I-shape. The length of the slider 13 is smaller than the length of the long hole 121. The vertical plate on the slider 13 is located in the long hole 121, and the height of the vertical plate is slightly larger than the thickness of the driving plate 12. The width of the vertical plate is smaller than the width of the long hole 121, thereby reducing the friction force. The width of the horizontal plates at the upper and lower ends of the slider 13 is much larger than the width of the long hole 121.

[0028] Further, a lifting lug 11 is provided at the top of the gate 1. The lifting lug 11 is used to connect a steel wire rope or a screw rod, and the steel wire rope or the screw rod is used to connect a hoist so as to drive the gate 1 to lift and lower.

[0029] The above is only a preferred embodiment of the present invention and does not impose any limitation on the present invention. Any simple modification, change and equivalent structural transformation made to the above embodiments according to the technical essence of the present invention all fall within the protection scope of the technical solution of the present invention.
