Description

Technical Field

[0002] Water conservancy construction involves various engineering activities, such as dam construction, river dredging, reservoir restoration, etc. These projects often need to be carried out in or near water areas. Due to the particularity of water conservancy projects, the working environment and safety requirements involved are complex and unique. Therefore, designing a safety protection device for water conservancy construction has become a vital task.

[0003] After searching, the existing patent (Announcement No.: CN212641266U) discloses a safety protection device for water conservancy project construction, which relates to the technical field of water conservancy projects. The safety protection device for water conservancy project construction includes a counterweight block, and the upper surface of the counterweight block is fixedly connected with a support frame and two support rods from left to right in sequence, and the ends of the two support rods away from the counterweight block are fixedly connected with grooves, and the upper surface of the support frame is fixedly connected with two mounting blocks. The safety protection device for water conservancy project construction can adjust the height of the warning sign by moving the warning sign up and down driven by the first inclined plate and the second inclined plate. By setting the support rod, the groove, the square block and the vertical rod, the groove can be supported by the support rod and the warning sign can be supported by the square block. At the same time, the vertical rod will not affect the up and down movement of the warning sign, thereby solving the problem that the existing warning sign cannot adjust the height, so that the protruding objects easily block the warning sign.
