They are a common type of water conservancy equipment. By opening and closing the water diversion gate, the flow rate and direction of the water flow can be reasonably controlled to ensure that the water penetrates into the soil evenly, meet the irrigation requirements, and protect the ecological environment of the farmland. In the prior art, in water conservancy irrigation, the opening and closing of the gate can be used to perform graded water release irrigation or water storage operations, but the existing water conservancy irrigation has the following problems: when the gate is opened for irrigation, the water flow will carry fish and other organisms in the water into the field. After the irrigation is over, these fish will die due to the cut-off of the water source, which not only affects the ecological environment in the field, but also causes a decrease in the number of fish in the stored water source, thereby affecting the overall ecological balance of the farmland.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figures 1 to 13As shown, a water diversion gate for irrigation of a water conservancy project described in an embodiment of the present invention comprises an outer frame 1 and a gate 11; the inner wall of the outer frame 1 is slidably connected with the gate 11; a shutter 12 is fixedly installed on the top of the outer frame 1; a lifting rod 13 is provided at the top of the gate 11, and the top of the lifting rod 13 is connected to the shutter 12, and the lifting rod 13 realizes the lifting action through the shutter 12; a first groove 14 is provided in the middle of the bottom end of the gate 11, and the cross-section of the first groove 14 is T-shaped; a pair of first sliding grooves 15 symmetrically distributed about the first groove 14 are provided on the outer surface of the gate 11; a sliding rod 16 is slidably connected in the first sliding groove 15, and one end of the sliding rod 16 extends into the first groove 14 and is fixedly connected with a round plate 2; the round plate 2 is slidably connected between the side walls of the first groove 14; the other end of the sliding rod 16 is fixedly connected with a connecting rod 17, and the connecting rod 1 The other end of 7 extends out of the first slide groove 15 and is fixedly connected to a vibration ball 18; two pairs of vibration plates 19 are fixedly connected to the outer wall of the gate 11, and each pair of vibration plates 19 is symmetrically distributed about the first slide groove 15 at the corresponding position; one side of the circular plate 2 is provided with a power part for driving its reciprocating movement; in the prior art, in water conservancy irrigation, the opening and closing of the gate 11 can be used to carry out graded water release irrigation or water storage operations, but the existing water conservancy irrigation has the following problems: when the water flow is irrigated, the gate 11 is in an open state, but when the water flow flows, it will carry fish and other organisms in the water into the field through water irrigation. After the fish enter the field soil, the water source is no longer continuously supplied after the irrigation ends, resulting in the death of the fish. The death of the fish affects the ecological environment in the field, and also causes a decrease in the fish in the stored water source, affecting the overall ecology of the farmland (fish feces mixed with water flow flowing into the field will increase the fertility of the farmland). To this end, when the present invention is working, when the gate 11 is opened, water flows out through the gate 11, and the power part drives the circular plate 2 to move back and forth under the action of the water flow. The circular plate 2 moves back and forth, which will drive the sliding rod 16 and the connecting rod 17 to drive the vibration ball 18 to push back and forth. The vibration ball 18 pushes back and forth and collides with the vibration plate 19 back and forth. The collision will produce high-frequency sound. By utilizing the diffusion of water flow, the fish around the gate 11 can be dispersed, and the fish are prevented from gathering and flowing out of the gate 11 through the flow of water. By diffusing the vibration sound, the possibility of fish flowing out through the gate 11 is greatly reduced, thereby ensuring the integrity of the overall ecology of the farmland.

[0020] The power member includes a lifting plate 21; a pair of symmetrically distributed lifting plates 21 are provided in the first groove 14, and the bottom ends of the lifting plates 21 pass through the gate 11; a first rotating shaft 22 is rotatably connected between the pair of lifting plates 21; both ends of the first rotating shaft 22 are fixedly connected to a first bevel gear 25; a pair of lifting plates 21 are fixedly connected to a fixed plate 24 on one side away from each other, and a telescopic rod 23 is rotatably connected to the fixed plate 24, and the bottom end of the telescopic rod 23 is rotatably connected to the bottom end of the first groove 14; the top end of the telescopic rod 23 is fixedly connected to a second bevel gear 26, and the first bevel gear 25 and the second bevel gear 26 on the same side are meshed with each other; a vertical column 27 is fixedly connected to the outer edge of the top end of the second bevel gear 26, and the vertical column 27 is slidably connected to the inner wall of the circular plate 2; a group of arc plates 28 are fixedly connected to the shaft wall of the first rotating shaft 22 located between the pair of lifting plates 21; the lifting plate 21 is connected with a gear for driving the lifting plate 21 to move up and down When the gate 11 is opened, the lifting plate 21 moves downward through the lifting unit, thereby driving the first rotating shaft 22 and the curved plate 28 to move downward, and the bottom end of the curved plate 28 extends out of the gate 11. At this time, when water flows out of the gate 11, it pushes the curved plate 28 to rotate, thereby driving the first rotating shaft 22 to rotate. Because the first bevel gear 25 and the second bevel gear 26 are meshed, the water flows out of the gate 11, which drives the curved plate 28 to rotate. The second bevel gear 26 is driven to rotate, and the rotation of the second bevel gear 26 will drive the circular plate 2 to move back and forth through the vertical column 27, thereby completing the back and forth push of the circular plate 2, and completing the vibration treatment of the vibration plate 19 by the vibration ball 18. At the same time, when the gate 11 is closed, the arc plate 28 will be retracted as a whole into the first groove 14 through the lifting unit, which will not affect the upper and lower closing of the gate 11. At the same time, when the gate 11 is opened, the arc plate 28 is rotated by the push of the water flow, without additional force, saving energy.

[0021] The lifting unit includes a lower pressure plate 3; the top of the lifting plate 21 is fixedly connected to a lower pressure column 31, and the top of the lower pressure column 31 is fixedly connected to the lower pressure plate 3 after extending out of the top of the gate 11; a lower pressure spring 32 is fixedly connected between the lower pressure plate 3 and the top of the gate 11; the top of the gate 11 is fixedly connected to a covering box 33, and the lower pressure plate 3 is located in the covering box 33; during operation, when the gate 11 is opened, the lower pressure plate 3 is contracted by the lower pressure spring 32, and then moves downward through the lower pressure column 31, driving the lifting plate 21 to move downward, allowing the arc plate 28 to extend out of the first groove 14. When the gate 11 is closed, the lifting plate 21 will first fit against the bottom end of the outer frame 1. When the gate 11 continues to move downward, the lifting plate 21 will move up, thereby driving the arc plate 28 to shrink into the first groove 14, completing the closing of the gate 11 and the shrinkage of the arc plate 28.

[0022] A positioning plate 41 is fixedly connected to the outer wall of the gate 11; a symmetrically distributed second slide groove 45 is provided on the outer wall of the gate 11; a square box 4 is provided on the outer wall of the gate 11, the top of the square box 4 is provided with an opening, and the bottom of the square box 4 is evenly provided with filtering holes; a pair of symmetrically distributed sliding blocks 46 are fixedly connected to the side wall of the square box 4; the sliding blocks 46 are slidably connected in the second slide groove 45; a waterproof telescopic cloth 42 is fixedly connected between the positioning plate 41 and the bottom end of the square box 4; a water pump 43 is fixedly connected to the bottom end of the positioning plate 41; a group of concave floating plates 44 are fixedly connected to the outer wall of the square box 4; the sliding blocks 46 are slidably connected to the second slide groove 45; When working, the square box 4 is in the water source. At this time, when the square box 4 floats through the concave floating plate 44, it can only ensure that the top of the square box 4 is always floating on the water surface, rather than floating out of the water surface. Because the positioning plate 41 is fixed on the outer wall of the gate 11, the waterproof telescopic cloth 42 can be unfolded when the square box 4 floats. At the same time, when the water pump 43 and the undulating member are working, the square box 4 fluctuates up and down through the undulating member, which can allow surface water flow to flow in and drive surface garbage to enter. At the same time, the water pump 43 can work to make the water flow in the square box 4 flow out, ensuring that the water flow in the square box 4 will not gather, thereby ensuring the collection of surface garbage (garbage collection is intermittent, which is convenient for the square box 4 to adjust its height following the water surface).

[0023] The undulating member includes a second rotating shaft 5; a pair of symmetrically distributed second rotating shafts 5 are rotatably connected on the inner wall at the top end of the covering box 33; the bottom end of the second rotating shaft 5 extends into the second slide groove 45; a servo motor 53 is fixedly connected to the top end of the covering box 33, and the output end of the servo motor 53 is connected to the second rotating shaft 5; a transmission wheel 51 is fixedly connected to the outer wall at the top end of the second rotating shaft 5; a pair of the transmission wheels 51 are driven by a transmission belt 52; the sliding block 46 is slidably sleeved on the shaft wall of the second rotating shaft 5; a cross groove 54 is provided in the shaft body of the second rotating shaft 5 located in the second slide groove 45, and the two sides of the cross groove 54 are in a through groove state; a T-shaped block 55 is slidably connected in the cross groove 54, and a sliding column 56 is provided on the side wall of the T-shaped block 55, and the sliding column 56 extends out of the cross groove 54; an annular inclined groove 57 is provided on the sliding inner wall of the sliding block 46, and the sliding column 56 slides The servo motor 53 is connected in the annular bevel groove 57; the T-shaped block 55 is limited by the positioning unit; when working, when the second rotating shaft 5 is rotated by the servo motor 53, the T-shaped block 55 and the sliding column 56 will be driven to rotate. At the same time, the T-shaped block 55 is limited by the positioning unit. The rotation of the sliding column 56 will drive the sliding block 46 to move up and down due to the setting of the annular bevel groove 57, and then drive the square box 4 to move up and down. When the servo motor 53 is not working, the limit of the T-shaped block 55 is released, and the square box 4 will follow the up and down movement of the water surface through the concave floating plate 44, keeping the top of the square box 4 and the water surface in a level state. At the same time, the up and down movement of the square box 4 will drive the T-shaped block 55 to move up and down in the cross groove 54 through the annular bevel groove 57 and the sliding column 56, ensuring that the square box 4 and the T-shaped block 55 can rise and fall at the same time without the positioning unit (the width of the annular bevel groove 57 is slightly larger than the width of the sliding column 56).

[0024] The positioning unit includes a T-slot 6; a T-slot 6 is provided on the side wall of the T-block 55; the square end of the sliding column 56 is slidably connected to the T-slot 6, and the square end of the sliding column 56 is fixedly connected to the bottom of the T-slot 6 by a spring; a pair of symmetrically distributed positioning blocks 61 are fixedly connected to the circular end of the sliding column 56, and the positioning blocks 61 are located in the opening groove of the T-slot 6; two groups of positioning grooves 62 symmetrically distributed about the through groove of the cross groove 54 are provided on the side wall of the cross groove 54; during operation, when the second rotating shaft 5 rotates, it will drive the T-block 55 to rotate, and then the sliding column 56 will be pushed outward under the action of centrifugal force, so that the positioning block 61 is stuck in the positioning groove 62, at this time, the T-block 55 will be subjected to the upper and lower limit operation, and then when the sliding column 56 rotates, it is set through the annular inclined groove 57, thereby driving the sliding block 46 to move up and down, completing the up and down fluctuation of the square box 4.

[0025] The positioning block 61 is set in a square shape; a group of third grooves 63 are opened on the side wall of the positioning block 61; the bottom of the third groove 63 is fixedly connected to the limiting block 64 by a spring; when working, the positioning block 61 fits into the positioning groove 62, and a group of limiting blocks 64 are set to ensure that when the square box 4 follows the ups and downs of the water surface, the positioning block 61 is locked into the positioning groove 62, and the limiting blocks 64 can be set to ensure the locking effect, and at the same time reduce the adjustment of the ups and downs height (if only the positioning block 61 is locked into the positioning groove 62, the height of the T-shaped block 55 When limiting, because the height of the water surface is in a random state, but the position of the positioning slot 62 is in a fixed state, there is a situation where the positioning cannot be achieved. The intervals between a group of positioning slots 62 block the entry of the positioning block 61. Although during the rotation of the T-shaped block 55, the positioning block 61 can be inserted into the positioning slot 62 due to the rotation adjustment, but this will also cause the fluctuation height of the square box 4 to change. By setting a group of limiting blocks 64, the interval problem of a group of positioning slots 62 can be avoided, and the fluctuation height change of the square box 4 can be ensured to be basically at a fixed value).

[0026] A pair of symmetrically distributed first cavities 7 are provided in the gate 11, and the first cavity 7 is located below the second slide groove 45; the bottom end of the first cavity 7 is rotatably connected to the first sprocket 71, and the bottom end of the second rotating shaft 5 extends into the first cavity 7 and passes through the middle of the first sprocket 71; the second sprocket 72 is fixedly connected to the outer wall of the bottom end of the telescopic rod 23; the first sprocket 71 and the second sprocket 72 are driven by a chain 73; the second rotating shaft 5 drives the first sprocket 71 to rotate through the connecting piece; when working, under normal working conditions, when the second rotating shaft 5 rotates counterclockwise, the first sprocket 71 will not be driven to rotate through the connecting piece, and thus garbage collection will not affect the rotation of the first rotating shaft 22. When the gate 11 is opened at the same height, when it is necessary to increase the impact force of the water flow, the second rotating shaft 5 can be rotated clockwise, and then driven by the connecting piece The first sprocket 71 is driven, and then the telescopic rod 23 is rotated through the arrangement of the first sprocket 71, the second sprocket 72 and the chain 73, and then the first rotating shaft 22 is rotated. At this time, the first rotating shaft 22 is rotated quickly to allow the water flow to rotate through the arc plate 28 to accelerate the outflow of the water flow and increase the impact force of the water flow. The impact force can be used to quickly flush the outflow position to avoid silt blockage. At the same time, the increase in the speed of the water flow is also convenient for cleaning the silt impurities at the bottom end of the outer frame 1, thereby ensuring the closing effect of the gate 11. The water flow can also be increased when the opening height of the gate 11 remains unchanged. At the same time, the knocking rate of the vibration ball 18 on the vibration plate 19 can also be increased to enhance the fish driving effect (generally, the water flow drives the first rotating shaft 22 to rotate, which is sufficient to disperse the fish, and the first rotating shaft 22 is driven to rotate by the second rotating shaft 5 to further enhance the effect).

[0027] The connecting member includes a second groove 74; a pair of symmetrically distributed second grooves 74 are opened on the shaft wall of the second rotating shaft 5 between the inner walls of the first sprocket 71; a positioning block 76 is fixedly connected to the bottom of the second groove 74 by a spring, and the end of the positioning block 76 is provided with an arc surface, and the pair of positioning blocks 76 are symmetrically distributed about the center point of the first sprocket 71; a pair of crescent grooves 75 symmetrically distributed about the center point of the first sprocket 71 are opened on the inner wall of the first sprocket 71; the transmission belt 52 is an "∞" belt; a pair of the first sprockets 71 are symmetrically distributed about the first groove 14; when working, when the square box 4 collects garbage, the second rotating shaft 5 rotates counterclockwise at this time, and will not The rotation of the first rotating shaft 22 in the first groove 14 is affected only when it is necessary to increase the water flow rate or the impact force of the water flow. At this time, the second rotating shaft 5 rotates clockwise, so that the vertical surface of the positioning block 76 and the vertical groove of the crescent groove 75 fit each other, so that the second rotating shaft 5 drives the rotation of the first sprocket 71, and then drives the telescopic rod 23 to rotate, and then through the rotation of the first bevel gear 25 and the second bevel gear 26, the first rotating shaft 22 and the arc plate 28 are quickly rotated (the transmission belt 52 is an "∞" belt, so that the rotation directions of a pair of second rotating shafts 5 are opposite, and then the rotation directions of a pair of telescopic rods 23 are opposite, and then the rotation directions of a pair of first bevel gears 25 are the same).

[0028] A square filter bag is detachably mounted on the top of the square box 4; during operation, a square filter bag (not shown) is detachably mounted in the square box 4, so that impurities can be easily removed, and the square filter bag will not affect the passage of water.

[0029] Working principle: When the gate 11 is opened, water flows out through the gate 11, and the lifting plate 21 moves down through the lifting unit, thereby driving the first rotating shaft 22 and the arc plate 28 to move down. The bottom end of the arc plate 28 extends out of the gate 11. When water flows out of the gate 11, it will push the arc plate 28 to rotate, thereby driving the first rotating shaft 22 to rotate. The first rotating shaft 22 rotates, and because the first bevel gear 25 and the second bevel gear 26 are meshed, it drives the second bevel gear 26 to rotate. The rotation of the second bevel gear 26 drives the circular plate 2 to move back and forth through the vertical column 27, and then drives the vibration ball 18 to push back and forth through the sliding rod 16 and the connecting rod 17. The vibration ball 18 pushes back and forth The vibration plate 19 will collide back and forth, and the collision will produce high-frequency sound. The water flow diffusion can disperse the fish around the gate 11, and prevent the fish from gathering and flowing out of the gate 11 through the flow of water. The diffusion of the vibration sound effectively reduces the situation of fish flowing out through the gate 11, ensuring the integrity of the overall ecology of the farmland; the square box 4 is in the water source. At this time, when the square box 4 floats through the concave floating plate 44, it can only ensure that the top of the square box 4 is always floating on the water surface, rather than floating on the water surface. Because the positioning plate 41 is fixed on the outer wall of the gate 11, the waterproof telescopic cloth 42 can be unfolded when the square box 4 floats. At the same time, when the water pump 43 and the ups and downs When the parts are working, the square box 4 rises and falls up and down through the undulating parts, which can allow the water flow on the surface to flow in, and at the same time drive the garbage on the surface to flow in. At the same time, the water pump 43 can work to make the water flow in the square box 4 flow out, ensuring that the water flow in the square box 4 will not gather, thereby ensuring the collection of surface garbage; under normal working conditions, when the second rotating shaft 5 rotates counterclockwise, it will not drive the first sprocket 71 to rotate through the connecting piece, and then the garbage collection will not affect the rotation of the first rotating shaft 22. When the gate 11 is opened at the same height, when it is necessary to increase the impact force of the water flow, the second rotating shaft 5 can be rotated clockwise at this time, and then drive the first sprocket 71 through the connecting piece, and then pass Through the arrangement of the first sprocket 71, the second sprocket 72 and the chain 73, the telescopic rod 23 is rotated, and then the first rotating shaft 22 is rotated. At this time, the first rotating shaft 22 is rotated quickly, and the water flow is allowed to rotate through the arc plate 28 to accelerate the outflow of the water flow and increase the impact force of the water flow. The impact force can be used to quickly flush the outflow position to avoid silt blockage. At the same time, the increase in the speed of the water flow is also convenient for cleaning the silt impurities at the bottom end of the outer frame 1, thereby ensuring the closing effect of the gate 11. It can also increase the water flow rate when the opening height of the gate 11 remains unchanged, and at the same time, it can also increase the knocking rate of the vibration ball 18 on the vibration plate 19 to enhance the fish driving effect.
