Description

Technical Field

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

[0002] In water conservancy projects, water flow regulation is very important. The gate controls the speed and flow of water by adjusting the size of the gate aperture and the height of the gate opening and closing, and discharges excess water levels or restricts the water level.

[0003] Application No. 202122467392.0 discloses a small canal gate for water conservancy projects. By setting a first filter mesh frame on the right side of the gate plate, floating garbage and impurities from the right side of the gate plate can be filtered. By setting a second filter mesh frame on the left side of the gate plate, floating garbage and impurities from the left side of the gate plate can be filtered. This avoids the disadvantage that existing small water conservancy gates still require cleaning personnel to waste a lot of manpower and material resources for cleaning.

[0004] The filter frame of the above application can only intercept the garbage in the water flow, but the accumulated garbage is easy to block the filter frame, thereby affecting the circulation of the water flow. Utility Model Content

[0012] The utility model provides a small-scale water conservancy project gate, which has the following beneficial effects:

[0013] 1. The gate for this small water conservancy project uses the salvage mechanisms set on both sides of the gate. While the filter net intercepts garbage and other debris in the water, multiple sets of tooth rakes on the conveyor belt automatically salvage the garbage and other debris ashore, which is convenient for cleaning the garbage accumulated on the filter net and helps to avoid clogging of the filter net and affecting the circulation of water.
