[0001] The utility model relates to the technical field of water conservancy engineering detection, in particular to a steel bar strength detection device for water conservancy engineering. Background Art

[0002] Water conservancy project quality inspection can be referred to as quality inspection. It refers to the activities carried out by water conservancy project quality inspection units to inspect, measure, test or measure water conservancy project entities and raw materials, intermediate products, metal structures and electromechanical equipment used in water conservancy projects in accordance with relevant national laws, regulations and standards, and compare the results with relevant standards and requirements to determine whether the project quality is qualified. Steel bar strength quality inspection mainly tests steel bars from aspects such as yield point, tensile strength and bending test.

[0003] After searching, the patent document with application number CN201721102363.1 discloses a steel bar strength detection device for water conservancy projects, including a fixed base, a second placement groove, a movable guide rail and a force rod. The first placement groove is installed at the inner left end of the fixed base, and an isolation plate is fixed to the right side of the first placement groove. The second placement groove is arranged on the right side of the fixed base, and support rods are installed on both sides of the top of the fixed base, and a steel bar placement groove is opened on the inner side of the support rod.

[0004] In the above-mentioned prior art, during detection, although the pressing height of the force rod can be changed by the movable guide rail, thereby changing different force sizes, which greatly improves the practicability of the steel bar strength detection device for water conservancy projects, when detecting the strength of steel bars, it is usually necessary to detect multiple steel bars. After the device detects one steel bar, each subsequent steel bar to be detected needs to be manually placed in the steel bar placement slot for detection. This method of manually placing multiple steel bars is not only troublesome, but also relatively cumbersome. Therefore, a steel bar strength detection device for water conservancy projects is now proposed. Utility Model Content
