Description

Technical Field

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

[0002] Gates are control facilities used to close and open water discharge channels. They are an important part of hydraulic structures and can regulate flow and upstream and downstream water levels, intercept water flow, discharge floods, regulate flow and discharge sediment to achieve benefits such as flood control, irrigation, water diversion and power generation, and sediment removal. They are control facilities used to close and open water discharge channels. There are many types of gates, which can be divided into flat gates, arc gates, flap gates, etc. according to the structural form. In canal irrigation applications, traditional valves usually use screws or motors to pull steel wire ropes to lift and lower the gates. Screws and steel wire ropes are eroded by wind, sun, and moisture all year round, and are easily rusted and damaged, requiring regular replacement. In addition, existing valves usually do not have a buffer structure. The water flow impacts the same position at the bottom of the canal for a long time, which is easy to cause damage to the cement structure at the bottom of the canal and shorten its service life. For this reason, we propose a diversion gate for water conservancy projects. Utility Model Content

[0009] Furthermore, cables are symmetrically provided at the rear end of the upper surface of the buffer plate, connecting rods are evenly provided at the front end between the two cables, and a limit block is provided on the upper surface of the gate seat. The connecting rod is cooperated with the front side of the limit block to adjust the angle of the buffer plate.

[0010] Furthermore, the upper surface of the buffer plate is evenly provided with guide strips, and the guide strips are all arranged in an S shape to divert water and reduce impact force.

[0011] Furthermore, through holes are evenly arranged inside the buffer plate to further disperse the water flow.

[0012] Furthermore, the left and right sides of the gate seat are provided with reinforcement plates to improve the firmness of the gate seat installation.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the diversion gate for water conservancy projects has the following advantages:

The transmission structure of the worm and the worm gear extends the service life, and solves the problem that the screw rod or wire rope in the traditional method is easy to rust and damage under the erosion of air and rain for a long time.

[0015] 2. The water flow is received by the buffer plate at the rear side of the gate seat. Part of the water disperses and flows downward through the through holes, and the other part flows downward from the rear end of the buffer plate under the guidance of the guide strip. The S-shaped structure of the guide strip can effectively reduce the impact force of the water flow and reduce the damage to the bottom of the canal.
