Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, in particular to an opening and closing device for a water conservancy gate. Background Art

[0002] A hydraulic gate is a facility used to control or regulate water flow. It is usually installed in waterways, reservoirs, lakes and other water bodies. It consists of one or more gates, which open and close channels by moving or rotating to control water flow. The design and construction of hydraulic gates can be varied according to different application scenarios and needs. Common types include flat gates, radial gates, vertical gates, etc. Flat gates are usually used in open waterways and canals. They have a simple structure, light weight, and are easy to install and maintain. Radial gates are suitable for occasions that require a larger opening and higher water level, such as regulating gates in large reservoirs and rivers. Vertical gates are gates that can move vertically and are suitable for occasions that need to quickly close waterways in a short period of time.

[0003] The patent document with application number CN202320166613.7 discloses a hydraulic gate opening and closing device, which includes a gate plate; the gate plate is arranged on the inner side of a concrete river channel, gate piers are arranged on both sides of the gate plate, a mounting frame is arranged at the upper end of the concrete river channel, and a power component for driving the gate plate to move vertically is installed on the mounting frame; a push plate is arranged at the inner bottom end of the concrete river channel, fixed blocks are arranged on both sides of the inner wall of the concrete river channel, guide rods A are connected to the two fixed blocks, the push plate is fixedly connected to a slide plate through the fixed rod, the slide plate is slidably installed on the two guide rods A, and there is a gap between the slide plate and the gate plate. A rotating rod is rotatably connected, and springs are sleeved and installed on the two guide rods A; a placement groove is provided at the inner bottom end of the concrete river channel, and a filter basket is provided on the inner side of the placement groove. Based on the search of the above-mentioned patent and in combination with the hydraulic gate opening and closing device in the prior art, it is found that when the above-mentioned hydraulic gate opening and closing device is used, in a turbulent water flow environment, the vertical gate directly blocks the water flow, causing the impact force of the water flow to directly act on the vertical gate, which may cause damage to the vertical gate, especially its track and gate knife, in the long run, affecting the normal use of the device. In addition, the application of the vertical gate in large waterways is also limited. Utility Model Content
