When the extrusion mechanism 7 extrude the test block, the extrusion mechanism 7 can be supported by the blocking mechanism 8, so that the extrusion mechanism 7 is more convenient for testing the test block. The heat preservation mechanism 2 can be protected with the cooperation of the mounting shell 1 to avoid the heat preservation mechanism 2 from being easily damaged. The inner wall of the mounting shell 1 is fixedly connected with a fixed shell 9, and a power mechanism 10 is installed on one side of the heat preservation mechanism 2. The inner cavity of the fixed shell 9 is provided with a connecting plate 11, and the surface of the connecting plate 11 is fixedly connected with a blocking frame. 12.

It is not only convenient, but also the integrated structural design is convenient to use. When the test block needs to be tested, the staff moves the extrusion mechanism 7 back to its original position through the hydraulic cylinder 5, and then moves the blocking plate 83 to make it receive the extrusion mechanism 7. Then the staff takes out the test block inside the insulation mechanism 2 and places it inside the fixed shell 9, and starts the servo motor 101 at the same time. With the cooperation of the servo motor 101 and the rotating rod 102, the bevel gear set 103 can drive the test block to rotate through the connecting disk 11, so as to reduce water stains on the surface of the test block. It is not only convenient, but also can quickly reduce water stains, thereby improving the detection efficiency of the test block. After the rotation is completed, the test block is taken out and placed inside the extrusion mechanism 7, and then the hydraulic cylinder 5 is opened to detect the test block.
