[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1: A cable immersion withstand voltage testing device, such as... Figures 1-7 As shown, it includes a housing 1, which serves as an overall frame. A control platform 2 is configured on the front side of the housing 1. This platform integrates key components such as a control module, precision instruments, and an intuitive display screen, providing users with a convenient operating interface and real-time data monitoring.

The lower part of the housing 1 is carefully designed with a water tank 4 to simulate the working state of the cable in a water immersion environment. The water injection pipe 41 at the bottom of the water tank 4 is cleverly inserted into the water tank and extends to the outside of the housing, which facilitates quick connection with external liquid supply equipment, realizes the precise injection and discharge of liquid in the water tank 4, and provides flexible and controllable water immersion conditions for testing.

[0025] A rotating shaft 51 is installed on the upper right side of the inner side of the housing 1. Its rear end is tightly connected to the rotating drive 5 on the rear side of the housing 1. This design allows the rotating shaft 51 to rotate smoothly under the drive of the rotating drive 5, thereby driving the mounting plate 6 fixed on it to change its angle. The rotating drive 51 drives the mounting plate 6 to rotate 90 degrees. Before the cable is placed, the mounting plate 6 and the wiring board 60 connected to it will be in a horizontal state. One end of the mounting plate 6 is provided with a wiring board 60. Multiple lead posts 65 arranged on it provide convenience for the cable arrangement and ensure the stable connection of the test circuit. When the wiring board 60 rotates 90 degrees counterclockwise, the wiring board 60 and the cable arranged on it will rotate into the water tank 4.

[0026] On the side of the mounting plate 6 away from the wiring plate 60, the clamping seat one 61 is arranged symmetrically in front and back, respectively used for stable placement of the live wire and the zero line in the cable, at the same time, the mounting plate is also symmetrically provided with the air cylinder 62, the movable rod end of which is connected through the pressing plate 63, the chuck one 64 arranged on the pressing plate 63 cooperates with the clamping seat one 61, when the movable rod of the air cylinder 62 is completely retracted, the chuck one 64 tightly matches with the clamping seat one 61, realizing the firm clamping of the exposed wire of the cable, ensuring the stability and safety of the cable in the test process.

[0027] Specifically, the device can automatically match the corresponding test conditions such as voltage, current and water immersion depth according to the test requirements of different types of cables through the preset intelligent program of the control module in the control platform 2, realizing the automation and precision of the test. In the test, the cable is rotated to the water tank 4 by rotating the driving part 5, in the test stage, the device can record and feedback the test data in real time, providing detailed test report for users, facilitating subsequent analysis and evaluation. The device not only realizes efficient and accurate test of different types of cables through its precise structure design and intelligent control system, but also effectively isolates the safety hazards in the test process through the setting of closed test environment, ensuring the safety of the operator, greatly improving the efficiency and quality of the test work.

[0028] Embodiment 2: on the basis of embodiment 1, as shown in Figures 2-4 The floating plate 7 is slidably connected to the pressing plate 63 through the guide rod 71, which makes the floating plate 7 freely move within a certain range while maintaining its stability, the spring 72 is wound outside the guide rod 71, the two ends of the spring are tightly connected with the guide rod 71 and the floating plate 7 respectively, providing continuous elastic support for the floating plate 7, the mounting plate 6 is additionally provided with the clamping seat two 73 symmetrically in front and back on the side close to the wiring plate 60, and the side of the floating plate 7 facing the clamping seat two 73 is equipped with two chuck two 74, which perfectly match with the clamping seat two 73, forming another stable cable clamping structure;

[0029] When the cable is placed on the clamping seat one 61 and the clamping seat two 73, the air cylinder 62 drives the pressing plate 63 and the floating plate 7 to approach the cable at the same time, until the chuck one 64 and the chuck two 74 firmly clamp the cable between the clamping seat one 61 and the clamping seat two 73 respectively, in this process, the elastic force of the spring 72 enables the floating plate 7 to make fine adjustment according to the actual diameter of the cable, ensuring the tightness and adaptability of the clamping, effectively avoiding the entanglement or falling off of the cable in the test process, thereby ensuring the accuracy and safety of the test.

[0030] In addition, as shown in Figures 3-4As shown, the utility model adds transmission part 8 and discharge rod 81, the transmission part 8 is arranged on the one end of mounting panel 6 away from wiring board 60, the slider equipped thereon can drive discharge rod 81 to move freely in the front and back direction, when discharge rod 81 moves to contact the cable conductor on the clamp seat 61, the discharge operation of cable can be realized, this design not only simplifies the test procedure, and improves the efficiency of test.

[0031] As shown in Figure 2 、 Figure 5 and Figure 6 , the utility model still sets up detection instrument 9 vertically on sink 4, for real time monitoring whether cable exists insulation failure, and detection needle of detection instrument 9 accurately extends into the lower part in sink 4, contacts the liquid in sink 4, to realize the real time monitoring of cable insulation performance, provides more comprehensive, accurate data support for test.

[0033] The shell 1 is also connected with the fixing block 103, which is composed of a connecting block and a convex rod, the convex rod of the fixing block 103 is embedded in the guide groove of the slide rod 102, forming a stable sliding connection, wherein the end of the convex ring 10 is provided with an inclined surface, which will first contact the lower end of the slide rod 102 during the clockwise rotation of the convex ring 10, and gradually lift it upward.

[0034] When the rotating drive 5 drives the rotating shaft 51 and the convex ring 10 to rotate clockwise, the convex ring 10 will contact the lower end of the slide rod 102 and generate a pushing force, causing the slide rod 102 to slide upward in the guide seat 101. With the upward pushing of the slide rod 102, the fixing block 103 is also pushed upward accordingly, and then drives the cover plate 3 to rotate upward through the connecting block. In this process, the convex rod of the fixing block 103 makes a circular motion with the opening of the cover plate 3, and the guide groove in the slide rod 102 leaves the space required for the upward movement and swinging action of the convex rod.

[0035] Through the cover opening mechanism, the mechanical linkage between the rotation of the rotating shaft 51 and the opening of the cover plate 3 is realized, without the need for additional power source or complex control mechanism, which simplifies the structure of the equipment and improves the convenience of operation. When the cable detection is completed, the cover plate 3 can be automatically opened by driving the rotating shaft 51 to rotate through the rotating drive 5.
