Abstract
Description
Technical Field
[0001] This invention relates to the field of hydraulic gate technology, specifically to a hydraulic gate with a self-cleaning function. Background Technology
[0002] Hydraulic gates are control facilities used in the development of water resources to close and open water discharge channels, prevent floods, and are an important component of hydraulic structures. They are used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris. Under natural conditions, insufficient or uneven rainfall often fails to meet the water requirements of crops, leading to artificial irrigation to compensate for insufficient natural rainfall. However, currently used gates have some shortcomings in their operation, as follows:
[0003] Water conservancy gates intercept water flow for extended periods. However, prolonged irrigation or disuse can cause debris such as weeds, mud, and sand in the river water to clog or adhere to the gates. This can obstruct the gates when they are opened later, affecting their efficiency and causing corrosion, thus extending their service life. Summary of the Invention
[0004] This invention provides a hydraulic gate with a self-cleaning function, which has the advantages of good water blocking effect and self-cleaning ability, thus solving the problems in the background art.
[0005] This invention provides the following technical solution: a hydraulic gate with self-cleaning function, comprising a dam body, wherein symmetrical limit grooves are formed inside the dam body, and a gate is movably installed in the limit grooves. The gate is movably engaged with the dam body. Gears are symmetrically fixed at both ends of the gate, and pulleys are fixedly connected to the sides of the gears. A steering roller is movably installed inside the dam body and located above the right of the limit groove. A winding roller is movably installed on the dam body and located below the steering roller. A steel strip is fixedly connected to the winding roller. The other end of the steel strip passes through the steering roller and the pulley in sequence and is fixedly connected to the inner wall of the upper right of the limit groove. A square groove is formed on the dam body and located below the limit groove. A rack is movably engaged in the square groove. The rack is engaged with the gear. A hydraulic telescopic rod I is fixedly installed inside the dam body and located below the rack. The extended end of the hydraulic telescopic rod I is fixedly connected to the bottom surface of the rack. The limit plate is movably engaged with the gate.
[0006] Preferably, the limiting groove forms an angle of 30-45 degrees with the horizontal plane, the width of the limiting groove is the same as the diameter of the gate, and the tooth pitch of the rack is smaller than the tooth pitch of the gear.
[0007] Preferably, the gate has an internal cavity, and the cavity is connected to a hydraulic pump via a conduit.
[0008] Preferably, the gate is provided with uniformly spaced slots, in which a debris removal plate is movably engaged. Hydraulic telescopic rods II are uniformly and fixedly installed inside the gate, with the extended ends of the hydraulic telescopic rods II fixedly connected to the inner side of the debris removal plate. A limiting plate is movably installed inside the dam body and below the gate, with a rotating shaft fixedly installed at the left end of the limiting plate. The rotating shaft is movably sleeved with the dam body. A piston groove is provided inside the dam body and below the limiting plate, with an arc-shaped hydraulic rod movably sleeved inside the piston groove. A connecting valve is fixedly installed on the dam body and at the left end of the piston groove. Hydraulic telescopic rods III are symmetrically and fixedly installed inside the dam body and above the right side of the gate, with the extended ends of the hydraulic telescopic rods III movably sleeved with limiting wheels.
[0009] Preferably, the piston groove, the arc-shaped hydraulic rod, and the rotating shaft on the limiting plate are concentric.
[0010] The present invention has the following beneficial effects:
[0011] 1. By designing the gate to be cylindrical, the gate's structural strength is enhanced. Furthermore, hydraulic oil can be injected into it, increasing its stability through its own weight and reducing the load on the supporting structure. Additionally, the limiting groove allows water to flow out from below the gate during discharge, ensuring contact between the bottom of the gate and the water flow. The impact of the water flow causes the gate to rotate, cleaning away debris adhering to its outer surface and ensuring its cleanliness. This prevents excessive debris from affecting the gate's sealing performance.
[0012] 2. By setting up the limit plate and the debris removal plate, when it is necessary to clean up the debris accumulated on the left side of the gate but a large amount of water cannot be released, the hydraulic telescopic rod II extends and retracts at a certain frequency. The hydraulic telescopic rod II drives the debris removal plate to extend on the left side of the dam body, carrying a certain amount of debris out from below. After reaching the right side, the debris removal plate retracts. In this way, a small amount of water is released, and the gate is rotated, thereby clearing the accumulated debris and preventing it from accumulating at the gate location, thus improving the cleanliness of the gate.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1-2A self-cleaning hydraulic gate includes a dam body 1. A limiting groove 2 is symmetrically formed inside the dam body 1. A gate 3 is movably installed in the limiting groove 2 and is movably engaged with the dam body 1. Gears 4 are symmetrically fixedly installed at both ends of the gate 3, and pulleys 5 are fixedly connected to the sides of the gears 4. A steering roller 6 is movably installed inside the dam body 1 and above the right of the limiting groove 2. A winding roller 7 is movably installed on the dam body 1 and below the right of the steering roller 6. A steel belt 8 is fixedly connected to the winding roller 7. The other end of the steel belt 8 passes through the steering roller 6 and the pulley 5 in sequence and is fixedly connected to the inner wall of the upper right of the limiting groove 2. A gate 3 is movably installed on the dam body 1 below the limiting groove 2. There is a square groove, in which a rack 9 is movably engaged. The rack 9 engages with a gear 4. Inside the dam body 1, below the rack 9, a hydraulic telescopic rod I 10 is fixedly installed. The extended end of the hydraulic telescopic rod I 10 is fixedly connected to the bottom surface of the rack 9. A limiting plate 11 is movably engaged with the gate 3. When intercepting river water, the gate 3 slides to the bottom of the limiting groove 2 under the action of gravity, engaging with the dam body 1 to intercept the water on the left side of the dam body 1. During this process, the hydraulic telescopic rod I 10 presses against the rack 9, thereby forcing the rack 9 to rise and engage with the gear 4, limiting the gate 3. Under the limiting action of the limiting plate 11, This allows the gate 3 to effectively intercept water, preventing water loss. Simultaneously, when it's necessary to open the gate to release water, the rack 9 is first pulled downwards, releasing the restriction on the gear 4. The winding roller 7 then rotates, winding up the steel strip 8. Under its pull and the impact of the water flow, the gate 3 rises along the limiting groove 2, opening the gate and allowing water to flow out from below. During this outflow, the bottom of the gate 3 comes into contact with the water flow, and the impact of the water flow causes the gate 3 to rotate, cleaning any debris adhering to its outer surface. This ensures the cleanliness of the gate 3 surface and prevents excessive debris from affecting its sealing performance. The limiting groove 2 forms a 30-45 degree angle with the horizontal plane. The width of the limiting groove 2 is the same as the diameter of the gate 3, so that the gate 3 can rise along the limiting groove 2 when it is opened, allowing the water flow to pass under the gate 3. The tooth pitch of the rack 9 is smaller than the tooth pitch of the gear 4, so that the rack 9 can lock the gear 4, preventing the gate 3 from rotating and rising along the rack 9 under the action of water pressure. The gate 3 has a cavity inside, and the cavity in the gate 3 is connected to a hydraulic pump through a conduit. When it is necessary to close the gate, hydraulic oil is injected into the interior of the gate 3 to increase the overall weight of the gate 3, thereby increasing the stability of the gate 3 in sealing under the action of gravity.
[0021] Please see Figures 3-5The gate 3 has evenly spaced slots, in which a cleaning plate 16 is movably engaged. Hydraulic telescopic rods II 15 are evenly fixedly installed inside the gate 3, with their extended ends fixedly connected to the inner side of the cleaning plate 16. A limiting plate 11 is movably installed inside the dam body 1, below the gate 3. A rotating shaft is fixedly installed at the left end of the limiting plate 11, and is movably sleeved with the dam body 1. A piston groove 12 is formed inside the dam body 1, below the limiting plate 11, and an arc-shaped... A hydraulic rod 13 is fixedly installed on the dam body 1 at the left end of the piston groove 12. A connecting valve 14 is fixedly installed inside the dam body 1 at the upper right of the gate 3. A hydraulic telescopic rod III 17 is symmetrically fixed inside the dam body 1 at the upper right of the gate 3. The extended end of the hydraulic telescopic rod III 17 is movably sleeved with a limit wheel 18. When the connecting valve 14 is opened, it connects with the bottom of the water. Under the action of water pressure, the arc-shaped hydraulic rod 13 is pressed against the limit plate 11, which in turn presses against the limit plate 11, making the limit plate 11 tightly connected to the gate 3, supporting the gate 3 and improving its height. For sealing purposes, when it is necessary to clear the debris accumulated on the left side of gate 3, but a large amount of water cannot be released, the connecting valve 14 is closed, and the arc-shaped hydraulic rod 13 is retracted, causing the limit plate 11 to retract, opening the gap below gate 3 for a small amount of water release. Simultaneously, the hydraulic telescopic rod III 17 drives the limit wheel 18 to descend, allowing the limit wheel 18 to support the upper right side of gate 3 and disengaging the rack 9 from the gear 4. Subsequently, the hydraulic telescopic rod II 15 extends and retracts at a certain frequency. The hydraulic telescopic rod II 15 causes the debris removal plate 16 to extend from the left side of the dam body 1, carrying a certain amount of debris out from below. After reaching the right side, the debris removal plate 16 retracts, thereby releasing a small amount of water and causing the gate 3 to rotate, thus removing the accumulated debris and preventing it from accumulating at the location of the gate 3, improving the cleanliness of the gate outlet. The rotating shafts on the piston groove 12, the arc-shaped hydraulic rod 13, and the limiting plate 11 are concentric, which allows the arc-shaped hydraulic rod 13 to slide in the piston groove 12, improving the utilization rate of water pressure.
