Description

Technical Field

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

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. Trench excavation is one of the more common construction processes in earthwork projects. During the trench excavation process, the loose soil often causes the trench slope to collapse, which can cause casualties in serious cases. Therefore, corresponding protective measures should be taken during the trench excavation process to ensure the stability of the trench slope.

[0003] The patent with the patent announcement number CN20191752078U discloses a trench excavation support device for water conservancy projects, which belongs to the technical field of water conservancy projects. It aims at the problems of inconvenient adjustment of trench slope support operation and poor stability of support after trench excavation, and comprises a placement frame, a cover plate is fixed on the top surface of the placement frame, four symmetrically distributed plug posts are fixed on the bottom surface of the placement frame, the inner wall of the placement frame is rotatably connected with a rotating shaft, and the inner wall of the placement frame is provided with an adjustment gear which is tightly sleeved with the outer surface of the rotating shaft; the utility model realizes the movement of the resistance pads on both sides to the connection between the bottom surface of the trench and the slope for abutment processing through the rotation of the rotating wheel, releases the force on the pressing block and the I-shaped rod, so that the resistance pads are stably installed at the connection between the bottom surface of the trench and the slope, and realizes the angle rotation adjustment processing of the two support plates on the resistance pads through the tightening of the two support bolts at the same height, and effectively fits with the inclined slope surface of the slope to improve the support performance of the trench slope. The above patent has the following shortcomings: Although the patent can improve the support performance of the groove slope, most of the existing safety protection devices for water conservancy construction block or buffer the impact of water flow through the cooperation of support plates and water retaining plates. Some safety protection devices for water conservancy construction block or buffer the impact of water flow through the cooperation of buffer springs and sliding columns. However, due to structural and design limitations, the buffer structure is single. Therefore, we propose a support device for water conservancy projects. In view of this, we propose a support device for water conservancy projects. Utility Model Content

During the movement of the fixed block backwards, it will enter the airbag and squeeze the high-pressure gas in the buffer zone. The impact force is buffered and shock-absorbed by the compression of the high-pressure gas, thereby improving the protective strength of the protective plate against flood impact.

[0016] 2. When the protective plate moves backward, the ball screw will be driven to rotate, and the rotation of the ball screw will drive the brush to rotate. During the rotation of the brush, the stains on the front of the protective plate are cleaned, thereby avoiding time-consuming and labor-intensive manual cleaning and saving manpower.
