[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides a device for testing the insulation performance of cable protection pipes, referring to... Figures 1-5 A testing device for the insulation performance of cable protection pipes includes a base plate 1, a cable protection pipe 6, and a control module 13.
[0028] A bracket 2 is fixedly mounted on the base plate 1. A test barrel 3 is fixedly mounted on the bracket 2. An insulating layer 4 is fixedly mounted inside the test barrel 3. An insulating seat 5 is fixedly mounted inside the test barrel 3. Both the insulating layer 4 and the insulating seat 5 are made of silicone rubber. A cable protection tube 6 is inserted into the test barrel 3, with one end of the cable protection tube 6 connected to the insulating seat 5. A control module 13 is fixedly mounted on the bracket 2. A positive electrode test rod 9 is sealed and mounted on the insulating seat 5. One end of the positive electrode test rod 9 is connected to a wire 10, and one end of the wire 10 is connected to the control module 13. A negative electrode test rod 11 is sealed and mounted on the top of the test barrel 3. One end of 11 is connected to a second wire 12, and the other end of the second wire 12 is connected to the control module 13. Through the cooperative design between the detection barrel 3, the insulating seat 5, the sealing cover 7, the cable protection tube 6, the control module 13, the positive electrode detection rod 9, and the negative electrode detection rod 11, the cable protection tube 6 only needs to be inserted into the detection barrel 3. The detection water in the detection barrel 3 is separated by the interaction between the insulating seat 5, the cable protection tube 6, and the sealing cover 7. Then, the positive electrode detection rod 9 supplies electrical energy to the detection water in the cable protection tube 6, thereby achieving the effect of detecting the insulation performance of the entire cable protection tube 6.
[0029] In this method, a sealing cap is threaded to one end of the cable protection tube 6, and the sealing cap 7 is in contact with the detection barrel 3 to insulate and seal one end of the cable protection tube 6 to prevent leakage.
[0030] In this method, a mounting groove is provided on one side of the sealing cover 7, and an insulating rubber ring 14 is fixedly installed in the mounting groove. One side of the insulating rubber ring 14 is in close contact with the cable protection pipe 6, so as to play the role of insulation.
[0031] In this method, a handle 8 is fixedly installed on one side of the sealing cover 7 to facilitate the removal of the cable protection tube 6 from the test barrel 3.
[0032] In this method, the top of the test barrel 3 is provided with an insertion hole, which corresponds to the insulating base 5, so as to facilitate the connection of one end of the cable protection tube 6 to the insulating base 5.
[0033] In this method, the socket is compatible with the cable protection tube 6, and the insulation layer 4 is in close contact with the cable protection tube 6 to avoid leakage.
[0034] In this method, the insulating base 5 has a groove, and one end of the cable protection tube 6 moves in the groove. The groove is adapted to the cable protection tube 6, and the insulating base 5 and the cable protection tube 6 are in close contact to avoid leakage and thus avoid affecting the test results.
[0035] In this method, the test tank 3 contains test water, and the top of the test tank 3 is equipped with a water inlet pipe to activate the conductive medium. A drain pipe is provided on one side of the test tank 3. Both the water inlet pipe and the drain pipe are equipped with insulating valves for replacing the test water. The insulating valves include a valve body, a valve cover, and an insulating sealing gasket. The insulating valves can control the opening and closing of the drain pipe and the water inlet pipe, and also have an insulating effect. The specific structure and working principle of the insulating valves can be found in the literature with application number 201620577010.6, which is existing technology and will not be described in detail.
[0036] Working principle: In use, firstly, one end of the cable protection tube 6 is inserted into the detection bucket 3, and the other end of the cable protection tube 6 is tightly connected to the insulating seat 5. Then, the sealing cap 7 is installed on one end of the cable protection tube 6, ensuring that the insulating rubber ring 14 is in close contact with the inner wall of the cable protection tube 6. Thus, the interaction between the insulating seat 5, the cable protection tube 6, and the sealing cap 7 effectively separates the detection water in the detection bucket 3. Afterward, through the control and drive of the control module 13 and the cooperation of the first wire 10, electrical energy is supplied to the positive electrode detection rod 9. During this process, if the insulation performance of the cable protection tube 6 is qualified, the positive electrode detection rod 9 and the negative electrode detection rod 11 will not be connected; otherwise, the control module 13 will receive a power signal through the negative electrode detection rod 11 and the second wire 12 and remind the operator. In summary, this achieves the effect of rapid detection of the entire cable protection tube 6.
[0037] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, the insulation performance of the entire cable protection pipe 6 can be quickly tested, improving convenience and efficiency. Moreover, the structure is simple and the practicality is higher.
[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
