Description

Technical Field

[0001] The utility model relates to the technical field of gates, in particular to a lifting water gate for water conservancy projects. Background Technique

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. It is also called a water project. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the flow of water be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intake structures, channels, aqueducts, raft channels, and fishways to achieve their goals.

[0003] When ordinary water conservancy project water gates are used for a long time, they often encounter relatively large water pressure. The high water pressure will cause large deformations when the water gates move, seriously endangering the long-term stable use of the water conservancy project gates. Therefore, there is an urgent need for a water gate with relatively high stability.

[0004] In the existing Chinese patent CN211547634U, a lifting water gate for water conservancy projects, when solving the above problems, the power of the motor is transmitted to the gear through the first transmission wheel, the conveyor belt and the second transmission wheel, and then the vertical water gate is driven to lift through the transmission gear. After the motor stops working after adjusting the gate to an appropriate height, the motor will rotate idly, that is, the device cannot fix the gate at a specified height, so that the gate cannot be opened to release water. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, one of the purposes of the utility model is to provide a lifting water gate for water conservancy projects.

[0006] One of the purposes of the utility model is realized by adopting the following technical scheme:

[0007] A lifting water gate for water conservancy projects, including a steel plate. On both the left and right sides of the steel plate, a number of reinforcing ribs are fixedly connected. An opening is provided on the steel plate, and a gate panel is arranged in the inner cavity of the opening. On both the left and right sides of the gate panel, limiting grooves are provided. A limiting rail is movably inserted into the inner cavity of the limiting groove. Two through holes are provided at the top of the steel plate, and two bearings are fixedly connected to the top of the steel plate. A threaded pipe is fixedly inserted into the top of the bearing. Two threaded rods are fixedly connected to the top of the gate panel. The top ends of the threaded rods movably penetrate through the through holes and the threaded pipe. A worm gear is fixedly sleeved on the outer edge of the threaded pipe. A worm is arranged behind the worm gear. A driving rod is arranged between the two worms. The two ends of the driving rod fixedly penetrate through the adjacent worms. An electric motor is arranged at the right end of the driving rod.

[0008] Preferably, the cross-section of the limiting rail is a right triangle. The limiting rail is fixedly connected to the side wall of the inner cavity of the opening, and the limiting rail matches the limiting groove.

[0009] Preferably, the power output end of the electric motor is fixedly connected to the driving rod. The bottom of the electric motor is fixedly connected with a support seat. Screws are inserted near the four corners of the top of the support seat. The support seat is fixed to the top of the steel plate by the screws.

[0010] Preferably, a protective cover is fixedly connected to the top of the steel plate. The vertical distance between the top end of the threaded rod and the inner top of the protective cover is greater than the vertical distance between the top of the gate panel and the inner top of the opening.

[0011] Preferably, the threaded rod and the threaded pipe are in threaded connection, and the threaded rod matches the threaded pipe.

[0012] Preferably, the worm and the worm gear are meshed with each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the lifting water gate for water conservancy projects of the present utility model, when water needs to be discharged, the electric motor drives the driving rod to rotate. The worm gear drives the threaded pipe to rotate in the inner cavity of the bearing and on the outer edge of the threaded rod. Under the action of the thread, the threaded rod drives the gate panel to move upward relative to the threaded pipe. Water passes through the opening from the front side of the steel plate and flows out from the rear side of the steel plate. After the gate panel is adjusted to an appropriate height, stop the electric motor. At this time, the gate panel will not drop, thus ensuring the normal progress of the water discharge work.

[0015] 2. For the lifting water gate for water conservancy projects of the present utility model, during use, the steel plate is cast and fixed at the water outlet. The stability of the steel plate is greatly enhanced through the reinforcing ribs, enabling the steel plate to have a better grip with the cast concrete.

[0016] 3. The lifting water gate for water conservancy projects of the present utility model. The gate panel moves within a defined trajectory through the action of the limit rail and the limit groove. Since the cross-section of the limit rail is set as a right triangle, impurities are prevented from accumulating on the limit rail when discharging water, thereby ensuring the normal operation of the limit rail.
