[0026] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an experimental device for water supply, drainage and heating engineering inspection, so as to solve the problem that the existing experimental device for water supply, drainage and heating engineering inspection proposed in the above background technology generally needs to perform anti-bending inspection test, but the anti-bending inspection is fixed at one position, and the pipeline needs to be moved for inspection, and it is not possible to perform anti-bending tests on the object to be inspected under different temperature conditions to obtain more comprehensive inspection data, which is not conducive to improving the safety and accuracy of the inspection experiment.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Among them, when it is necessary to conduct inspection experiments on water supply and drainage and heating projects, the inspector places the object to be inspected on the limit frame 14, starts the hydraulic rod B16 according to the specifications of the object to be inspected, pushes the fixed plate 17 to fix the object to be inspected, and then starts the drive motor 4, the positive and negative threaded rods 5 drive the movable frame 6 to change position, starts the hydraulic rod A7, pushes the pressing block 8, and sets the threshold of the heating temperature through the temperature controller 22, so that the heating resistance wire 20 heats the heating plate 21 according to the set temperature threshold, and squeezes different positions of the object to be inspected at different temperatures with different intensities, thereby simulating the high temperature environment that the object to be inspected may encounter in actual work, helping to evaluate the anti-bending performance of the simulated object to be inspected under such conditions, avoiding the need to constantly move the object to be inspected, causing the object to be inspected to fall off, endangering the inspector, and only being able to test the anti-bending performance under the current environment, affecting the comprehensiveness of the inspection data, and improving the safety and accuracy of water supply and drainage and heating project inspection experiments.

[0030] Two sliding rings 10 are welded on both sides of the top surface of the two moving frames 6 , and a guide rod 11 is slidably connected inside the sliding ring 10 . Three linkage rings 12 are welded on the bottom surface of the moving frame 6 .

[0031] The guide rod 11 is installed on the other two connection blocks 3, and the sliding ring 10 follows the moving direction of the moving frame 6 and slides on the surface of the guide rod 11, which helps to improve the stability of the movement.

[0032] Three slide grooves are provided on the surface of the experimental table body 1 , and linkage rods 13 are fixedly connected to both sides of the inner walls of the slide grooves.

[0033] The linkage ring 12 on the bottom of the moving frame 6 is sleeved on the surface of the linkage rod 13. When the moving frame 6 moves, the linkage ring 12 slides on the linkage rod 13 to maintain the movement stability of the bottom of the moving frame 6 and improve the detection effect.

[0035] The object to be detected is placed in the limiting frame 14. Since the limiting frame 14 is curved, it can prevent the object to be detected from sliding to the edge, and the anti-slip pad A can protect it.

[0036] The two sides of the detection frame 2 are fixedly connected with transverse plates 15 , and the bottom surface of the transverse plate 15 is fixedly connected with a hydraulic rod B16 .

[0037] According to the specifications of the object to be detected, the hydraulic rod B16 installed at the bottom of the horizontal plate 15 is used to push the fixing plate 17 to fix the object to be detected.

[0042] One side of the heating resistance wire 20 is electrically connected to a temperature controller 22 via a power line. The temperature controller 22 is fixedly installed inside the moving frame 6 .

[0043] By adjusting the heating temperature threshold of the temperature controller 22, the high temperature environment that the inspection object may encounter in actual work is simulated to help evaluate the anti-bending performance of the material under such conditions.

[0044] Working principle: When the experimental device for water supply, drainage and heating engineering inspection is used, the inspector places the object to be inspected on the limit frame 14, and according to the specifications of the object to be inspected, the hydraulic rod B16 is started, and the fixed plate 17 is pushed to fix the object to be inspected, and the anti-skid pad B18 and the anti-skid pad A fix its position to prevent sliding while protecting its surface, and then the drive motor 4 is started, and the positive and negative threaded rods 5 drive the moving frame 6 to change its position, and the hydraulic rod A7 is started to push the pressing block 8, and the threshold of the heating temperature is set through the temperature controller 22, so that the heating resistance wire 20 heats the heating plate 21 according to the set temperature threshold, and different positions of the object to be inspected are squeezed at different temperatures with different intensities, thereby simulating the high temperature environment that the object to be inspected may encounter in actual work, helping to evaluate the anti-bending performance of the simulated object to be inspected under such conditions, avoiding the need to constantly move the object to be inspected, causing the object to be inspected to fall off, endangering the inspector, and only being able to test the anti-bending performance under the current environment, affecting the comprehensiveness of the inspection data, and improving the safety and accuracy of the water supply, drainage and heating engineering inspection experiments.
