[0049] In use, the device is first adjusted according to the testing requirements. The corresponding number of unit test cylinders 7 are connected in series and installed between symmetrical fixed test frames 101 according to the length of the test cable, forming the testing environment. Then, the adjusting motor 504 drives the adjusting wheel 5 to rotate through the adjusting gear 503 and adjusting gear disc 502, rotating the test clamping seat 6 of the required size to the uppermost or lowest working position. Then, the elastic locking pin 404 is inserted into the locking hole 505 to lock the adjusting wheel 5. Next, the closed sleeve 204 with the corresponding size clamping channel 205 is fitted into the clearance connecting sleeve 202 of the conical closed bag 201. After adjustment, the test cable is passed through one side of the fixed test frame 101, through the closed sleeve 204, through the conical closed bag 201, and then through all the unit test cylinders 7 in sequence until it reaches the other side of the fixed test frame 101. Then, the hydraulic telescopic rod 302 extends, causing the vertically symmetrically arranged clamping seats 3 to move synchronously up and down to move closer to each other, thereby bringing the symmetrically arranged test clamping seats 6 closer together to clamp and fix them. The test cable is fixed at both ends on symmetrical fixed test frames 101. A heat-conducting medium is supplied through the circulating delivery pipe 703 to regulate the temperature inside the unit detection cylinder 7, providing the necessary temperature environment for cable testing. Then, the horizontal hydraulic rod 103 extends, causing the pulling translation seat 104 to slide horizontally along the horizontal guide frame 102, pushing the pulling translation seats 104 in the two fixed test frames 101 to move away from each other, thus performing a pulling test on the cable. At this time, the sliding detection seat 4 moves relative to each other to compress pressure. Sensor 304 can determine the tensile force on the cable. During the icing test, the spray pipe 901 in the annular spray frame 9 sprays water mist through the test nozzle 902 on its inner side to adjust the humidity inside the unit detection cylinder 7. By adjusting the water pressure pumped into the spray pipe 901, the water mist is sprayed directly onto the test cable at the center of the unit detection cylinder 7. The temperature inside the unit detection cylinder 7 is also adjusted to simulate the cable being in icy weather, so that ice naturally forms on the outside of the cable, thus completing the cable test.

[0050] A method for using a multi-environment experimental device for cable performance testing includes the following steps: First, adjust the device according to the testing requirements. Then, based on the length of the test cable, connect and assemble a corresponding number of unit test cylinders 7 in series between symmetrical fixed test frames 101 to form the testing environment. Next, adjust the motor 504 to drive the adjusting wheel 5 to rotate via the adjusting gear 503 and adjusting gear disc 502, rotating the test clamp 6 of the required size to the uppermost or lowest working position. Then, the elastic locking pin 404 is inserted into the locking socket 505 to lock the adjusting wheel 5. After adjustment, pass the test cable through one side of the fixed test frame 101 and sequentially through all the unit test cylinders 7 until reaching the other side of the fixed test frame 101. Then, the hydraulic telescopic rod 302 extends. The vertical clamping seats 3, which are symmetrically arranged, move up and down synchronously to move closer to each other, thereby bringing the symmetrical test clamping seats 6 closer together to clamp and fix the test cable between them. The two ends of the test cable are fixed on the symmetrical fixed test frame 101 respectively. At this time, the heat-conducting medium is transported through the circulating conveying pipe 703 to adjust the temperature inside the unit detection cylinder 7 and provide the required temperature environment for cable testing. Then, the horizontal hydraulic rod 103 extends and drives the traction translation seat 104 to slide horizontally along the horizontal guide frame 102, pushing the traction translation seats 104 in the two fixed test frames 101 on both sides to translate and move away from each other to perform a traction test on the cable. At this time, the sliding detection seat 4 moves relative to each other to squeeze the pressure sensor 304, so that the value of the tension on the cable can be obtained, and the cable test is completed.

[0051] The multi-environment experimental device for cable performance testing provided by this invention uses a symmetrically arranged fixed test frame 101 to pull the two ends of the cable for testing. The middle of the cable is located inside multiple series-connected unit test cylinders 7. Each unit test cylinder 7 is equipped with heat-conducting fins 702 and a circulation conveying pipe 703. The heat-conducting medium can be conveyed through the circulation conveying pipe 703 to adjust the temperature inside the unit test cylinder 7, thereby providing different temperature environments for cable testing. The test environment is composed of multiple series-connected unit test cylinders 7, which are detachably connected. The length of the entire test environment can be adjusted by installing the corresponding number of unit test cylinders 7, which facilitates testing cables of different lengths and makes the testing experiment more convenient and flexible.
