[0026] Example:

[0027] See also Figure 1-4 The microcomputer-controlled insulator thermal engine test box includes a thermal engine test box 1 and a microcomputer 2. The microcomputer 2 is arranged on one side of the thermal engine test box 1. The thermal engine test box 1 is provided with a receiving chamber 4 and a test chamber 3 from top to bottom. The test chamber 3 and the receiving chamber 4 are provided with a tensile test mechanism and an environmental simulation mechanism. The tensile test mechanism and the environmental simulation mechanism cooperate to test the state of the insulator under use.

[0028] In this embodiment, the tension test mechanism and the environmental simulation mechanism are electrically connected to the microcomputer 2. When the insulator is tested, the insulator is placed in the test chamber 3, and the microcomputer 2 controls the tension test mechanism and the environmental simulation mechanism to start. The tension test mechanism performs a tension test on the insulator, and the environmental simulation mechanism simulates the outdoor ambient temperature between -60° and 60° to perform a temperature test on the insulator under the tension test. At the same time, the environmental simulation mechanism also performs a wind resistance test on the insulator; wherein the test chamber 3 is used for the placement test of the insulator, and the accommodating chamber 4 is used to accommodate some equipment in the tension test mechanism and the environmental simulation mechanism.

[0029] Specifically, the tensile testing mechanism includes a connecting seat 501, a cylinder 502 and a mechanical claw 503. The connecting seat 501 is fixedly connected to the bottom wall of the test chamber 3, the cylinder 502 is fixedly connected to the accommodating chamber 4, and the output end of the cylinder 502 passes through the test chamber 3. The mechanical claw 503 is arranged at the output end of the cylinder 502, and the mechanical claw 503 is located in the test chamber 3 corresponding to the connecting seat 501.

[0030] In this embodiment, when performing a tension test on the insulator, the insulator is placed in the test cavity 3 and connected to the corresponding connection seat 501. Then, the microcomputer 2 controls the cylinder 502 and the mechanical claw 503 to start. The cylinder 502 drives the mechanical claw 503 to move downward to clamp the top of the insulator. Finally, the cylinder 502 controls the mechanical claw 503 to retract, so that the insulator is subjected to a tension test, and the test results are directly fed back to the microcomputer 2.

[0031] Specifically, the environmental simulation mechanism includes an evaporator 601, a heater 602 and a circulating fan 603. The evaporator 601 and the cylinder 502 are fixedly connected in the test chamber 3. The circulating fan 603 is fixedly connected in the test chamber 3 and the accommodating chamber 4, and the circulating fan 603 passes through the test chamber 3 and the accommodating chamber 4.

[0032] In this embodiment, when the insulator is subjected to an environmental simulation test, the microcomputer 2 controls the evaporator 601, the heater 602 and the circulating fan 603 to start, and the evaporator 601, the heater 602 and the circulating fan 603 adjust the temperature inside the test chamber 3 to between -60° and 60°, and the insulator is subjected to a temperature test at the adjusted temperature. At the same time, the circulating fan 603 generates a certain wind force to conduct a wind resistance test on the insulator.

[0033] Specifically, a box door 7 is provided at the front end of the thermal engine test box 1 , and the box door 7 corresponds to the test chamber 3 .

[0034] In this embodiment, the box door 7 controls the opening and closing of the thermal engine test box 1 so that the insulator can be placed in the test cavity 3 .

[0035] Specifically, the box door 7 is provided with a perspective window 701 and a door handle 702 , and the door handle 702 corresponds to the test chamber 3 .

[0036] In this embodiment, the perspective window 701 allows the staff to observe the test conditions of the insulator in the test chamber 3 , and the door handle 702 makes it more convenient to open and close the box door 7 .

[0037] Specifically, the bottom end of the thermal engine test chassis 1 is fixedly connected to a base 8 , and a loading slope 9 is provided on the base 8 .

[0038] In this embodiment, the base 8 is used to support the thermal engine test box 1 so that the insulator remains stable during testing in the thermal engine test box 1. The loading slope 9 on the base 8 makes it more convenient to place the insulator into the thermal engine test box 1.

[0039] Working principle: When testing the insulator, the insulator is placed in the test chamber 3 and connected to the corresponding connection seat 501. The microcomputer 2 controls the cylinder 502 and the mechanical claw 503 to start. The cylinder 502 drives the mechanical claw 503 to move down to clamp the top of the insulator. Finally, the cylinder 502 controls the mechanical claw 503 to retract, so that the insulator is subjected to a tensile test. The test results are directly fed back to the microcomputer 2. At the same time, the microcomputer 2 controls the evaporator 601, the heater 602 and the circulating fan 603 to start. The evaporator 601, the heater 602 and the circulating fan 603 adjust the temperature inside the test chamber 3 to between -60° and 60°. The insulator is subjected to a temperature test at the adjusted temperature. In addition, the circulating fan 603 will generate a certain wind force according to actual needs when started to conduct a wind resistance test on the insulator.
