A hydraulic gate capable of controlling flow

Abstract

The present invention provides a water conservancy gate capable of controlling flow, and relates to the technical field of water conservancy gates. The water conservancy gate comprises a gate fixing frame, and limit bases are respectively installed on both side walls of the gate fixing frame, and a gate body is slidably clamped on the limit bases. A limit pressure plate is respectively installed on one side wall of the gate body, and an overflow gate is slidably clamped on the limit pressure plate.

When a large amount of water is released, the gate body is raised as a whole to increase the amount of water released. When the gate body falls, the silt on the positioning protrusion can be scraped off by the L-shaped limit block, so that the limit concave block can fit with the positioning protrusion, thereby ensuring the interception effect of the bottom of the gate body on the water flow, and at the same time, the water grass and sludge on the surface of the gate body can be scraped off by the T-shaped scraper, which can improve the service life of the gate body to a certain extent.

Description

Technical Field

[0001] The invention relates to a hydraulic gate capable of controlling flow, belonging to the technical field of hydraulic gates. Background Art

[0002] Compared with the construction of general civil engineering such as roads, bridges and house buildings, the construction of water conservancy projects has its own unique characteristics. Water conservancy projects undertake the tasks of water retaining, water storage and water discharge. Therefore, there are special requirements for the stability, pressure bearing, anti-seepage, impact resistance, wear resistance, frost resistance and crack resistance of hydraulic structures. It is necessary to adopt special construction methods and measures in accordance with the technical specifications of water conservancy projects to ensure the quality of the project. Among them, water conservancy gates are indispensable equipment in water conservancy and hydropower construction. The gates are used to control water flow, divert floods or create waterfall landscape lights. However, the existing water conservancy gates generally adopt the opening method of overall lifting. Regardless of the size of the gate opening, when the gate is opened, the bottom of the river always flows first, resulting in a large amount of silt at the bottom of the river mixed in the flowing water. Moreover, after the existing gates are opened, sludge is easily accumulated under the gates, resulting in the gates being unable to fit with the bottom of the river after closing again, thereby reducing the gate's blocking effect on the water flow. Moreover, one side of the gate is immersed in the water for a long time, and the surface is easily attached with water plants, mud and other debris, which will cause damage to the surface of the gate.

[0003] For example, announcement number CN212000932U discloses a water gate for a water conservancy project that is convenient for controlling water flow. A first gate is embedded and connected in a fitting groove located on one side of the gate pier, and a second gate is embedded and connected in a fitting groove located on the other side of the gate pier. The first gate can be stably raised and lowered from the fitting groove by mechanical lifting through the fitting groove, the first gate, the support rod, the movable seat, the push rod, the hydraulic cylinder and the fixed seat, and the second gate can be moved in the fitting groove by manual rotation adjustment through the second gate, the movable connecting seat, the screw rod and the rotating wheel. Therefore, when people adjust the water flow, they only need to close the first gate first, then adjust the second gate, and finally open the first gate to facilitate people to manually adjust the water flow quickly and accurately. The operation is simple and convenient, and the labor intensity is low.

[0004] For another example, announcement number CN214737849U discloses a water gate for a hydraulic project that is convenient for controlling water flow, including a drive box, a motor is arranged at the bottom of the inner cavity of the drive box, the output end of the motor is fixedly connected to a first gear, the outer side of the first gear is meshingly connected to a second gear, and the inner ring of the second gear is fixedly connected to a first threaded rod; by arranging the first threaded rod, the second threaded rod, the first connecting rod, the telescopic rod and the cylinder, water can be released, so that it is convenient for users to control the water flow, which solves the problem that when some existing hydraulic gates are raised and lowered, multiple gates cannot be raised and lowered. At the same time, when controlling the water flow, the water flow is controlled by controlling the lifting of the water gate. In this way, when a small amount of waterproofing and a large amount of waterproofing are required, they can only be controlled by one water gate, which increases energy loss and reduces work efficiency.

[0005] The above-mentioned prior art gates all use a method of directly lifting and lowering from the bottom to open the gates and release water. No matter how much water is released, as long as the water is released, there will always be a large amount of silt mixed in the water flow, resulting in poor quality of the released water. In addition, after the prior art gates are lowered again, there is often a gap between the bottom of the gates and the silt, resulting in a reduction in the gate's interception effect on the water flow. At the same time, aquatic plants and sludge are easily attached to the prior art gates, affecting the service life of the gates. Summary of the invention

[0006] The purpose of the present invention is to provide a water conservancy gate that can control the flow rate in order to solve the above-mentioned problem. The gate can be opened in sections, which can not only realize daily control of the water level, but also realize rapid water release during the flood season. At the same time, the gate can also avoid the influence of the sludge remaining under the gate on the gate when it is closed again, thereby ensuring the effect of intercepting the water flow after the gate is closed. The gate can also effectively clean the aquatic plants and silt attached to the surface of the gate, which can improve the service life of the gate to a certain extent.

When the gate is immersed in water for a long time, the driving pulley 1 at its output end is driven to rotate by rotating the motor 32, so that it can drive the support horizontal shaft 28 to rotate, so that the support horizontal shaft 28 can drive the driving pulley 29 to rotate, and then the driven pulley 27 can drive the ball screw 14 to rotate, and the ball screw 14 can drive the support bottom plate 15 to translate. In the process of the movement of the support bottom plate 15, the support spring 2 1603 drives the T-shaped scraper 1604 to press against the surface of the gate, so that the T-shaped scraper 1604 can scrape The water plants and sludge on the surface of the gate body 3 can be scraped off, thereby improving the life of the gate body 3 to a certain extent, and when the overflow gate 5 moves up and down, the water plants and sludge attached to the overflow gate 5 will also be scraped off.

The protective filter plate 35 can be used to control the water The garbage in the flow can be filtered, which is helpful to prevent too much garbage from flowing into the downstream river. When the water needs to be released quickly, the electric push rod 37 drives the clamping base plate 38 to move, so that the clamping joint 40 on the clamping base plate 38 can be clamped with the positioning hole on the protective filter plate 35, so that the protective filter plate 35 can be driven to move during the upward movement of the gate body 3, so as to ensure the subsequent water flow, and when the clamping joint 40 is clamped with the positioning hole on the protective filter plate 35, the clamping base plate 38 can be guided and supported by the limiting guide rod 39, so as to improve the stability of the clamping joint 40 on the clamping base plate 38 and the protective filter plate 35 when clamped.
