[0032] It is worth noting that the circuits, electronic components and modules involved in the present utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present utility model does not involve improvements to software and methods.

[0033] The working principle of the testing device for thermal deformation of granular cable materials provided by the utility model is as follows:

[0034] This solution also provides an electric control cabinet, which is arranged on the equipment. When in use, each electric device can be started and operated through the electric control cabinet. The power connection method of each electric device is an existing mature technology, which is a well-known technology for people in this field and will not be described in detail here (the deformation sensor in the placement box 5 is used to monitor the deformation of the granular cable material during the thermal deformation process in real time. The deformation sensor can be a non-contact laser displacement sensor or a contact pressure sensor, etc., which can accurately measure the deformation data of the cable material and transmit the data to the control and data processing module for recording and analysis. By monitoring the thermal deformation module, the thermal deformation performance parameters of the granular cable material under different temperature conditions can be obtained, providing reliable data support for cable manufacturing);

[0035] When in use, first, the operator opens the retractable box door 15 through the operating port, and puts the granular cable material to be tested into the detachable placement box 5. The design of the placement box 5 makes the placement and removal of the cable material simple and quick. At the same time, the setting of the slide and the slide plate ensures the stable movement of the placement box 5 on the assembly frame 4; then, the box door 15 is closed, the test device is started, and the electric hydraulic rod 3 drives the lifting extrusion plate 2 to descend, and the granular cable material in the placement box 5 is subjected to an extrusion test; a displacement sensor is provided on the extrusion plate 2 for real-time monitoring of the lifting position of the extrusion plate 2 to ensure precise control during the extrusion process, and the displacement data is fed back to the control and data processing module for subsequent data analysis and processing. Adjusting the stroke of the electric hydraulic rod 3 can achieve precise control of the extrusion force, so as to accurately evaluate the thermal deformation performance of the cable material; after the test is completed, the electric hydraulic rod 3 drives the extrusion plate 2 to rise and return to the initial position; at this time, the first motor 6 is started, and the assembly frame 4 is driven to flip through the connecting plate 7. Since the placement box 5 is connected to the assembly frame 4 through the slide and the slide plate, the placement box 5 and the tested cable material inside can be stably flipped with the assembly frame 4 during the flipping process. When the assembly frame 4 flips to a suitable angle, the cable material in the placement box 5 falls into the processing bucket 8, and the operator can put it into the crushing mechanism; the second motor 10 drives the crushing roller 9 to rotate in the processing bucket 8 to crush the tested cable material. The crushed cable material falls into the receiving box 14 through the discharge port at the bottom of the processing bucket 8, which is convenient for subsequent cleaning and recycling; during the entire test process, the operator can observe the situation in the test box 1 through the transparent observation window, and understand the test progress and the deformation of the cable material in real time. The sealing design of the test box 1 effectively prevents heat loss and ensures the accuracy and stability of the test.
