Description

Technical Field

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

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. However, the current state of natural existence does not fully meet human needs. At this stage, only by building water conservancy projects can we control water flows, prevent floods and disasters, and regulate and distribute water. Gates are generally installed in water conservancy projects. Gates are control facilities used to close and open drainage channels. They can be used to intercept water flows, control water levels, regulate flow rates, discharge sediment and floating objects, etc.

[0003] In the related technology, through searching, the publication number is: CN219118089U, a lifting type hydraulic gate, through the filter plate, when the gate is opened to release water or discharge debris, when the water flow drives the debris to rush out of the gate frame body, the debris will be blocked by the filter plate, so that the debris will not flow downstream, causing pollution of downstream water resources or environment, so that when the gate is opened, only water can pass through, and the debris will be blocked, so as not to pollute downstream water resources. However, after long-term use, a large amount of debris will adhere to the outside of the filter plate, blocking the filter plate and affecting the normal passage of water. At the same time, it is more difficult to clean the debris outside the filter plate. For this reason, we propose a lifting type hydraulic gate.

[0004] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content
