Description

Technical Field

[0001] The invention relates to a flow control gate for water conservancy projects, belonging to the technical field of water conservancy project equipment. Background Art

[0002] Water conservancy project is a broad concept, which covers many water-related engineering projects. The main purpose of these projects is to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They include flood control, waterlogging removal, irrigation, power generation, water supply, reclamation, soil and water conservation, immigration, water resource protection and other projects (including new construction, expansion, reconstruction, reinforcement, repair) and their supporting and ancillary projects. Water conservancy projects are not only related to human production and life, but also have a profound impact on the ecological environment. Among them, the gate for water flow control is a basic device used in water conservancy projects. In water conservancy projects, it plays a vital role, and the development of gates is relatively extensive.

[0003] For example, according to the Chinese invention patent with publication number: CN113389180A, a power-generating gate for water conservancy projects includes: a baffle; a rectangular shell fixedly disposed at the bottom end of the front side of the baffle, and the left and right sides of the rectangular shell are through-shaped; a cylindrical shell fixedly disposed at the front side of the rectangular shell; a support frame fixedly disposed between the cylindrical shell and the baffle; a generator set disposed in the inner cavity of the cylindrical shell; a connecting pipe fixedly connected to the cylindrical shell and communicating with the inner cavity of the power generation component; a water outlet mechanism disposed on one side of the baffle; and an opening and closing mechanism disposed on the outside of the rectangular shell. The power-generating gate for water conservancy projects can control the outflow of water, and can concentrate water into the circular hole to increase the flow rate of water. By controlling the water switch, the potential energy of the water flow is used to generate hydroelectric power, so as to protect energy, be easy to implement, and be more suitable for use in water conservancy projects.

[0004] The effect of generating electricity by using the gate is achieved.

[0005] For example, the Chinese invention patent with publication number: CN108867575A is used for flow control gates in water conservancy projects. Its structure includes a fixed layer, a gate mounting frame, a gate control device, and a fixed seat. The gate mounting frame is arranged on the fixed seat, and the gate mounting frame and the fixed seat are vertically welded. The fixed layer is arranged at the upper part of the gate mounting frame, and the fixed layer and the gate mounting frame are established as an integrated structure. The beneficial effects of the present invention are as follows: by setting a rectangular water outlet in the center of the reinforcement plate, a small flow of water flows out through the rectangular water outlet, thereby achieving a stable supply of small flow of water, using a cylinder drive rod to drive the bearing to move and drive the turntable to rotate through the central axis, so that the clamping rod cooperates with the clamping slot, and the movable gate plate is driven to rise and fall through the L-shaped drive rod, thereby achieving effective control of the water flow, and solving the problem of inconvenience in control caused by corrosion of the threads on the screw in traditional screw start-stop gate control.

[0006] Another example is the Chinese invention patent with publication number: CN113605327A, a water conservancy engineering gate capable of controlling water flow and speed, comprising a side frame fixedly installed in the gate, and a top plate and a base are welded on the side frame respectively. The present invention uses a first-stage gear and a second-stage gear, a third-stage gear and a rack to set a pressing block and a connecting block driven by a motor to move up and down on the top plate of the side frame, and the upper connecting rod and the lower connecting rod are used to pull the first-stage gate plate, so that the first-stage gate plate can be moved up and down smoothly in the gate to realize the opening and closing of the first-stage gate plate; a bracket and a guide frame are set on the outside of the side frame, and a steel cable is used to pull the second-stage gate plate that can slide horizontally in the guide frame, so that the two second-stage gate plates can move horizontally smoothly; by controlling the horizontal movement degree of the second-stage gate plate, the first-stage through hole and the second-stage through hole in the first-stage gate plate and the second-stage gate plate are adjusted to overlap to different degrees according to the actual needs of water purification and impurity removal, so as to purify and remove impurities from the water flow passing through the gate.

[0007] However, when in use, when the gate is lifted, the water flows at the bottom of the gate. Due to the deadweight pressure of the water body, the impact on the bottom of the river channel is too great, which can easily cause the bottom of the riverbed to be hollowed out. As a result, after the gate has been used for a long time, holes appear at the bottom of the riverbed. It is inconvenient to operate when releasing small amounts of water, and when releasing water, the impact of the water flow causes serious damage to the riverbed, making it inconvenient to use in water conservancy projects. Summary of the invention

When a small flow rate is required to flow water, according to the required flow rate of the water, the corresponding number of the driving components are opened, so that the driving components drive the blocking components at the corresponding positions to rotate inside the groove, so that the blocking components are displaced from the water holes, thereby facilitating the water flow through the water holes through the technical solution, and when the water flows through, the buffer component is used to buffer the impact force of the water flow, reduce the scouring effect of the impact force of the water flow on the river channel, and facilitate long-term use, ensure the stability of the bottom of the river channel during long-term use, and prevent the effect of hollowing. When a medium water flow rate is required to release water, all the driving components are opened, so that all the blocking components are displaced from the water holes, so that the water flows through all the water holes. When a large flow rate is required to release water, the gate assembly is pulled upward inside the frame assembly, so that the gate assembly moves to the upper end inside the frame assembly, thereby facilitating the water flow to quickly circulate through the lower end of the frame assembly, which is convenient for controlling the flow effect, has strong applicability, and is convenient for use according to different water flow requirements.

[0010] Furthermore, the frame assembly includes a gate frame, a lifting slot is vertically opened on the inner side of the gate frame, both sides of the plate body are slidably engaged in the lifting slot in a vertical state, guide holes are opened on both sides of the upper end of the gate frame, the upper end of the gate assembly extends to the inside of the guide hole, and a pin plate is placed on the upper end of the gate frame, the pin plate is pinned to the gate assembly, and the lifting slot inside the gate frame is used to facilitate the lifting and lowering of the gate assembly inside the gate frame, and the position of the gate assembly can be adjusted conveniently, and the guide hole can be used to further improve the lifting and lowering stability of the gate assembly during lifting, and the pin plate can be placed to pin the pin plate to the gate assembly after the lifting is completed, so as to avoid the gate assembly from falling due to its own gravity after the adjustment is completed, thereby improving the stability during use.

[0011] Furthermore, an internal threaded sleeve is fixedly installed in the middle position of the upper end of the gate frame, and the middle position of the upper end of the gate assembly is threadedly connected to the internal threaded sleeve. Through the fixed connection of the internal threaded sleeve, the height of the gate assembly can be easily controlled, and the lifting operation is convenient.

[0012] Furthermore, an adjusting screw with a handwheel on the upper end is rotatably installed in the middle position of the upper end of the plate body, and the adjusting screw is threadedly connected to the internal threaded sleeve, and the upper end of the plate body is located on both sides of the adjusting screw with T-shaped guide rods fixedly installed, the guide rods are inserted into the inside of the guide hole, and the guide rods are provided with pin holes in a vertical array, and the pin plate is inserted into the inside of the pin hole. When performing a lifting operation, the handwheel on the upper end of the adjusting screw is rotated to make the adjusting screw rotate on the plate body and lift and lower along the internal threaded sleeve, so as to facilitate the adjustment of the position of the plate body inside the gate frame, and during adjustment, the guide rod moves inside the guide hole, and after the adjustment is completed, the position of the plate body is fixed by inserting the pin plate into the inside of the pin hole to prevent the self-lifting effect.

[0013] Furthermore, both sides and the lower end of the plate body are concave structures, and an airbag cushion is fixedly installed inside the concave structure, and inflation and deflation nozzles are fixedly installed at both ends of the airbag cushion. The airbag cushion is pressed tightly against the inner side of the frame assembly, and an axial hole is opened at the middle position of the inner part of the groove. The blocking assembly is rotatably installed inside the axial hole. After the plate body descends to the lower end of the gate frame, since the airbag cushion is located inside the lifting slide slot and the airbag cushion is inflated by the inflation and deflation nozzle, the airbag cushion seals the gap between the plate body and the gate frame to avoid water leakage and improve the blocking effect during water blocking. Moreover, the axial hole facilitates the rotation of the blocking assembly inside the groove, so that the rotation angle of the blocking assembly can be controlled conveniently when a small flow rate is flowing.

[0014] Furthermore, rib plates are evenly fixedly installed on the back water side of the plate body, the grooves are located between the rib plates, and through holes are transversely opened on the rib plates. The middle position of the driving component is slidably installed inside the through holes. The rib plates are used to improve the water blocking effect of the plate body and avoid deformation.
