Description

Technical Field

[0001] The utility model relates to the field of cable branch boxes, in particular to a waterproof high-voltage cable branch box. Background Art

[0002] The cable branch box is a device used to connect and distribute cables. Its main function is to branch the main cable into multiple secondary cables and distribute electrical energy to different electrical equipment or circuits.

[0003] In the Chinese patent application number: CN202222735361.3, a cable branch box is disclosed. Through the setting of the ventilation mechanism, when the cable branch box is in use, the ventilation net can be fixedly installed by using the fixing bolts, and then the ventilation net can be used to ventilate and dissipate heat inside the box, so as to avoid the condensation phenomenon caused by the air not circulating inside the cable branch box, and the long-term high temperature will accelerate the aging of the cable branch box. At the same time, the protective plate is pulled, and the protective plate is driven to move by the slider under the interaction between the slide groove and the slider, so as to protect the ventilation net, and the limit rod is inserted into the inner side of the limit groove, and the position of the protective plate can be fixed under the action of the limit groove and the limit rod;

[0004] However, the cables inside the cable branch box may age and break after long-term use, resulting in leakage. Compared with the waterproof cable branch box in the patent, it is difficult to monitor the leakage of the cables, so it is difficult to repair the leaking cables in time, which can easily affect the safe use of the cable branch box. For this reason, we propose a waterproof high-voltage cable branch box. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a waterproof high-voltage cable branch box.

[0010] Furthermore, the leakage monitoring component also includes a spring, one end of the spring is fixedly connected to the inner wall of the limiting sleeve, and the other end of the spring is fixedly connected to an arc-shaped limiting plate.

The spring exerts a reaction force on the arc-shaped limit plate to clamp the high-voltage cable bodies of different diameters and limit them. The spacing between adjacent limit sleeves can also be finely adjusted by sliding the slider.

[0012] Furthermore, the high-voltage cable body passes through the connection frame and the current sensor and is movably connected to the connection frame and the current sensor, the springs are arranged equidistantly, and the arc-shaped limit plates are arranged equidistantly.

[0013] Furthermore, the current sensor is electrically connected to a PLC controller, and the PLC controller is electrically connected to an audible and visual alarm.

When the high-voltage cable body leaks due to skin damage or other reasons, the current sensor monitors the change of current and transmits the current signal to the PLC controller. The PLC controller controls the corresponding sound and light alarm to flash and sound the whistle, so as to remind the operator to repair the high-voltage cable body in time;

[0020] 2. By setting the spring and the arc-shaped limit plate, when the high-voltage cable body passes through the limit sleeve, multiple arc-shaped limit plates will be squeezed outward and the spring will be compressed.
