[0002] The dam foundation refers to the foundation of the dam, including the riverbed and the parts on both sides where the dam is placed, and the adjacent parts that bear the impact of the dam and water. After the dam foundation is built, it needs to withstand the impact of waves. Nowadays, most dam foundations will install protective plates on the surface to protect the dam foundation, but the protection performance in other aspects is poor, such as safety protection.

[0003] After searching, the patent publication number is CN212641338U, which is a dam foundation protection device for water conservancy construction, and relates to the field of water conservancy technology. The dam foundation protection device for water conservancy construction includes a mounting plate, two cross bars are arranged in front of the mounting plate, the left and right end surfaces of the two cross bars are fixedly connected with fixed plates, the backs of the four fixed plates are fixedly connected with the front of the mounting plate, and the outer surfaces of the two cross bars are slidably sleeved with two sliders, the fronts of the two sliders on the left and the two sliders on the right are fixedly connected by elastic sheets, and the upper surfaces of the two fixed plates on the left and the upper surfaces of the two fixed plates on the right are fixedly connected by connecting plates. The dam foundation protection device for water conservancy construction achieves the effect of changing the impact direction of the waves and buffering them by setting stirring plates and elastic sheets, and solves the problem that the dam foundation is currently protected by installing protective plates on the dam foundation, but it is still directly impacted by the waves, which affects the safety of the dam foundation.

[0004] In the process of implementing the above scheme, it was found that the following problems in the prior art have not been well solved: the dam foundation protection device in the prior art is in a hollow state between the dam body, and no good safety measures are provided between them, resulting in poor safety protection performance for personnel. Therefore, it is urgent to design a water conservancy dam foundation protection device to solve the above problems. Utility Model Content
