[0021] When currently used, the existing technology is difficult to provide early warning when a water leak occurs, which may result in the water leak being discovered only after the cable fails, leading to an accident.

[0022] See also Figure 1-Figure 3 As shown, this embodiment provides a cable waterproof sealing structure, including an outer shell 10, which is composed of two arc-shaped shells. The end faces of the two arc-shaped shells are provided with sealing strips 12, and the two adjacent sealing strips 12 are meshed with each other to increase the sealing of the contact surfaces at both ends of the two arc-shaped shells. Sealing rings 11 are provided inside the two ends of the outer shell 10, and the surfaces of the two arc-shaped shells are provided with detection hosts 21. The inner walls of the two arc-shaped shells are provided with sensors 20. The sensors 20 are used to receive signals when water is inside the arc-shaped shells, and transmit the signals to the detection host 21 for alarm.

[0023] First, the sensors 20 are arranged linearly inside the housing 10. The main purpose is to facilitate detection of water leakage after water leakage occurs. The model of the sensor 20 is JRWIER24. When it comes into contact with liquid water, it will send a signal. The sensor 20 is connected to the detection host 21 through a wire. The main purpose is to transmit the water leakage signal to the detection host 21. The model of the detection host 21 is WKD-DS008. When it receives the signal, it can alarm, thereby achieving the purpose of water leakage warning.

[0024] Furthermore, four lug groups are provided on the side of the shell 10, and the lug group consists of two lugs 13. A locking nut 14 is provided in the middle of the lug group. Its main function is to reduce the distance in the middle by rotating the nut. The locking nut 14 locks the two lugs 13 in the lug group with each other. Its main function is to make the arc-shaped shell dock tightly and enhance the sealing.

[0025] Furthermore, the inner diameter of the housing 10 is larger than the outer diameter of the cable to prevent the sealing effect from deteriorating after locking. The inner diameter of the sealing ring 11 is smaller than the outer diameter of the cable. Its main purpose is to increase the waterproof effect of the sealing ring 11 through extrusion.

[0026] The cable waterproof sealing structure in this embodiment is used in specific applications:

[0027] Cover the two outer shells 10 at the connection of the used cables, pass the locking nut 14 through the support ear 13, and lock the locking nut 14 to make the sealing ring 11 squeeze the surface of the cable and the sealing strips 12 squeeze each other. When a water leakage accident occurs, the sensor 20 arranged inside will send a signal to the detection host 21 after the water contacts the sensor 20. After receiving the signal, the detection host 21 sends an alarm signal to prevent the water leakage from further spreading to the inside of the cable, and to provide early warning for maintenance to reduce losses.
