However, during the long-term use of the gate structure, impurities such as moss will grow on the sealing surface where the guide groove on the base contacts the gate body, thereby affecting the sealing of the gate. Summary of the invention

[0004] The present invention provides a gate structure for water conservancy and hydropower to solve the above problems.

[0005] The present invention discloses a gate structure for water conservancy and hydropower, which adopts the following technical scheme: a gate structure for water conservancy and hydropower, comprising a base, a gate plate, a sealing dam, a pressure relief dam, and an adjusting component.

[0006] The base is arranged front and back along the direction of water flow; the direction perpendicular to the water flow direction is set as the left and right direction; the base is fixed on the riverbed by cement pouring; the main dam body is fixed on the base; two main dam bodies are symmetrically arranged with respect to the direction of water flow; a drainage outlet is surrounded between the two main dam bodies.

[0007] The gate plate is arranged in the drain outlet; the gate plate is arranged perpendicularly to the direction of water flow; a vertically arranged reference axis is arranged on the gate plate; the distances from the left and right ends of the gate plate to the reference axis are equal; an adjustment groove is arranged on the upper end of the gate plate; the adjustment groove is arranged along the left and right directions; one end of the adjustment groove is set as a sealing end, and the other end is set as a pressure relief end; the pressure relief end and the sealing end are distributed on both sides of the reference axis; a slider is installed in the adjustment groove for left and right sliding; a lifting shaft is rotatably installed on the upper end of the slider; the lifting shaft is arranged above the gate plate through a lifting assembly; when the gate is closed, the lifting shaft is at the sealing end; when the gate is opened, the lifting shaft is at the pressure relief end.

[0008] There are two sealing dams; one sealing dam is arranged on the water-facing side of the gate plate and fixed on the main dam body close to the sealing end of the regulating tank, and the other sealing dam is arranged on the water-receiving side of the gate plate and fixed on the main dam body close to the pressure relief end of the regulating tank; the side wall of the sealing dam close to the gate plate is arranged as a sealing wall; the sealing wall is perpendicular to the direction of water flow; when the gate is closed, the two ends of the gate plate abut against the sealing wall.

[0009] There are two pressure relief dams; one pressure relief dam is arranged on the water-facing side of the gate plate and fixed on the main dam body close to the pressure relief end of the regulating tank, and the other pressure relief dam is arranged on the water-receiving side of the gate plate and fixed on the main dam body close to the sealing end of the regulating tank; blocks are fixed at the lower ends of the pressure relief dams; the distance between the blocks and the sealing wall on the same main dam body is greater than the thickness of the gate plate.

[0010] When the gate is opened, the regulating component drives the lifting shaft to drive the slider to the pressure relief end, so that the pressure of the water flow acting on the end of the gate plate close to the pressure relief end is less than the pressure of the water flow acting on the end of the gate plate close to the sealing end, so that the gate plate is deflected around the lifting shaft towards the pressure relief dam under the drive of the water flow, and the gate plate abuts on the stop block, and the water flows out from the gap between the gate plate and the pressure relief dam. While performing preliminary pressure relief, the water flow flushes the impurities such as moss grown on the sealing dam, thereby improving the sealing performance of the gate plate when the gate is closed. After the preliminary pressure relief, the lifting component drives the gate plate to move up, and the drain port is opened to discharge water. When closing the gate, the lifting shaft is driven to drive the slider to the sealing end, and then the lifting component drives the gate plate to move downward. The pressure of the water flow acting on the end of the gate plate close to the pressure relief end is greater than the pressure of the water flow acting on the end of the gate plate close to the sealing end, so that the gate plate is deflected in the opposite direction around the lifting shaft towards the pressure relief dam under the drive of the water flow, and the gate plate is abutted against the sealing wall by the water flow pressure, so that the sealing performance between the gate plate and the sealing wall is improved while the gate is closed and the water is cut off.

[0012] Furthermore, the adjustment assembly includes a hydraulic rod; the hydraulic rod is arranged in the left and right direction; the hydraulic rod is arranged on one side of the mounting seat, the hydraulic rod is fixed on the mounting plate, and the piston rod of the hydraulic rod is fixedly connected to the mounting seat. The hydraulic rod drives the mounting seat to drive the lifting shaft to slide on the mounting plate, and the lifting shaft drives the slider to slide in the adjustment groove.

[0013] Furthermore, the driving assembly includes a rotating disk, which is fixed to the upper end of the lifting shaft. The rotating disk is rotated to drive the lifting shaft to rotate, thereby driving the gate plate to move up and down.

[0014] Furthermore, the side wall of the sealing dam near the gate plate is in an arc shape with a concave surface facing the center of the drainage outlet; the side wall of the pressure relief dam near the gate plate is in an arc shape with a concave surface facing the center of the drainage outlet. The arc-shaped side wall of the sealing dam and the arc-shaped side wall of the pressure relief dam are used to guide the water rushing into the drainage outlet to collide and converge, offset the impact of the water flow, reduce the impact of the water flow on the riverbed sediment, and reduce the probability of soil erosion.

[0015] Furthermore, the driving assembly includes a driving motor; the driving motor is fixed on a mounting seat; and an output shaft of the driving motor is fixedly connected to the lifting shaft.

[0016] Furthermore, auxiliary dam bodies are fixed to the front and rear ends of the main dam body away from the gate plate; the auxiliary dam bodies on both sides of the water flow and on the same side of the gate plate on the two main dam bodies are in a V shape with the small end facing the gate plate. It is used to collect water to impact the deflected gate plate when opening the gate, which is conducive to flushing and cleaning impurities such as moss on the gate plate.

[0017] Furthermore, a torsion spring is sleeved at the lower end of the lifting shaft; the upper end of the torsion spring is fixedly connected to the lifting shaft, and the lower end is fixedly connected to the slider. It is used to assist the gate plate to rotate and reset after the gate plate is lifted to release water and the water level drops, so that when the gate plate moves down to close the gate, the auxiliary gate plate and the sealing wall are tightly abutted.

[0018] Furthermore, guardrails are fixed on both sides of the installation plate; the two guardrails form a personnel passage.

[0019] Furthermore, an escalator is fixedly connected between the mounting plate and the main dam body.

[0020] The beneficial effects of the present invention are: 1. When opening the gate, the adjusting component drives the lifting shaft to drive the slider to move to the pressure relief end, so that the pressure of the water flow acting on the end of the gate plate close to the pressure relief end is less than the pressure of the water flow acting on the end of the gate plate close to the sealing end, so that the gate plate is driven by the water flow to deflect around the lifting shaft toward the pressure relief dam, the gate plate abuts on the block, and the water flows out from the gap between the gate plate and the pressure relief dam to perform preliminary pressure relief. At the same time, the water flow flushes impurities such as moss grown on the sealing dam, thereby improving the sealing of the gate plate when closing the gate.

[0021] 2. When closing the gate, the lifting shaft is driven to drive the slider to the sealing end, and then the lifting assembly drives the gate plate to move downward. The pressure of the water flow on the end of the gate plate close to the pressure relief end is greater than the pressure of the water flow on the end of the gate plate close to the sealing end, so that the gate plate is driven by the water flow to deflect in the opposite direction of the pressure relief dam around the lifting shaft, and the gate plate is abutted against the sealing wall by the water flow pressure, so as to close the gate and cut off the water while improving the sealing between the gate plate and the sealing wall.

[0022] 3. The arc-shaped side walls of the sealing dam and the arc-shaped side walls of the pressure relief dam are used to guide the water flowing into the drainage outlet to form a collision and convergence, offset the impact force of the water flow, reduce the impact of the water flow on the riverbed sediment, and reduce the chance of soil erosion.
