[0002] Water conservancy detection is an activity carried out by water conservancy project quality inspection units in accordance with relevant national laws, regulations and standards. It involves inspecting, measuring, testing or gauging water conservancy project entities, as well as raw materials, intermediate products, metal structures and electromechanical equipment used in water conservancy projects, and comparing the results with relevant standards and requirements to determine whether the project quality is qualified. Its main purpose is to ensure the construction quality, safety and stability of water conservancy projects, so as to ensure that water conservancy projects can operate normally and play their expected benefits.

[0003] In order to ensure project quality, during the implementation of water conservancy projects, it is generally necessary to detect the strength of dams. When detecting dams, generally a piece is cut, and then, an electric cylinder drives a pressing plate to move, the pressing plate presses the test piece, and then a pressure sensor detects the strength of the test piece. During the whole detection process, as the pressing plate presses, the pressure on the extruded test piece gradually increases. After the test piece breaks, it will splash in a large area around, which is not easy to clean and may harm the staff.

[0004] Therefore, it is necessary to provide a new dam strength detector for water conservancy detection to solve the above technical problems. Content of the Utility Model
