The cable connection port 2 is provided with a sealing assembly, which comprises two hydraulic devices 5 fixedly installed in the cable connection port 2, the output ends of the two hydraulic devices 5 are fixedly provided with a moving plate 6, the side wall of the moving plate 6 is fixedly provided with a plurality of isolation plates 7 arranged in a staggered manner, a rotating cylinder 12 is rotatably and penetratingly connected in the moving plate 6, a moving rod 10 is symmetrically sleeved in the rotating cylinder 12 relative to the moving plate 6, a telescopic rod 13 is fixedly connected to the side wall of the moving rod 10 and fixedly connected to the moving plate 6, a through slot 23 is formed in the moving rod 10, a control rod 27 is slidably connected in the through slot 23, a sliding rod 28 is fixedly connected to the outer side of the control rod 27, a threaded groove 34 is formed in the rotating cylinder 12, and the sliding rod 28 is slidably connected to the threaded groove 34. Figure 8 、 Figure 9 As shown in FIGS. 6 and 7, the side wall of the moving rod 10 is provided with an opening 25 for the movement of the sliding rod 28, one end of the sliding rod 28 is slidably connected to the threaded groove 34, a power assembly for controlling the rotation of the rotating cylinder 12 is installed on the outer side of the moving plate 6, the power assembly comprises a rotating rod 8 rotatably penetrating the moving plate 6, the rotating rod 8 and the rotating cylinder 12 are drivingly connected through a belt pulley assembly 14, the side of the rotating rod 8 away from the moving plate 6 is fixedly provided with a gear 9, and a rack 11 is fixedly installed in the cable connection port 2 and engaged with the gear 9. In the process of electrical connection, the aluminum foil tape is wound around the outer side of the cable (here, the cable does not refer to one cable, but to all cables passing through the cable connection port 2, i.e., a cable bundle), to ensure that the cable is firmly fixed, then the aluminum foil tape area is passed through the isolation plate 7 during the clamping and fixing operation of the cable, the hydraulic device 5 is started, the moving plate 6 and the isolation plate 7 are moved towards each other under the action of the hydraulic device 5, until the isolation plate 7 abuts against the aluminum foil tape, in this process, since the rack 11 is in a fixed state, the gear 9 moving with the rotating rod 8 will rotate, the rotating rod 8 drives the rotating cylinder 12 to rotate through the belt pulley assembly 14, at this time, one end of the sliding rod 28 is located in the threaded groove 34, and the moving rod 10 is connected to the isolation plate 7 in a sliding manner under the limiting action of the telescopic rod 13, and the threaded groove 34 is divided into two sections, and the threaded directions of the two sections are opposite, therefore, the rotating rotating cylinder 12 drives the moving rod 10 to move towards the isolation plate 7, i.e. Figure 6From the perspective of the moving rod 10, the upper moving rod 10 moves downward, and the lower moving rod 10 moves upward. Since the moving rod 10 also moves with the moving plate 6 during this process, the upper moving rod 10 moves downward and to the right as a whole, and the lower moving rod 10 moves upward and to the right as a whole, until the moving rod 10 is inserted into the cable bundle, the moving rod 10 abuts against the aluminum foil tape, and the aluminum foil tape is pressed, the cable bundle and the aluminum foil tape are clamped and fixed, and the moving rod 10 and the aluminum foil tape are fixed in cooperation, which not only prevents the cable from moving due to the external force of the shell 1, but also prevents the cable from moving due to the internal force of the shell 1 during operation (for example, when the compressor is working, different pressures may cause the transportation pipeline to move, the transportation pipeline abuts against the cable, and the cable moves), that is, the cable moves too far, which affects the normal operation of the circuit.

[0015] The automatic disconnecting assembly is installed outside the moving rod 10, the automatic disconnecting assembly comprises a control block 22 slidably installed in the through slot 23, a control spring 31 fixedly connected between the control block 22 and the through slot 23, a control shaft 33 fixedly connected to the lower side of the control block 22 through a right-angle rod 32, two control plates 38 rotatably connected to the outer upper and lower sides of the control shaft 33, a torsion spring 39 fixedly connected between the two control plates 38 and the control shaft 33, a torque sensor fixedly connected between the two control plates 38, a clamping rod 41 fixedly connected to the outer sides of the two control plates 38, an electro-hydraulic servo cylinder 40 fixedly connected in the through slot 23, the control rod 27 and the output end of the electro-hydraulic servo cylinder 40 are fixedly connected, the control rod 27 is fixedly connected with the square rod 16, the moving plate 6 is fixedly connected with the fixed frame 15, two sliding grooves 24 are opened in the inner side wall of the through slot 23, two sliding blocks 29 are slidably connected in the two sliding grooves 24, a reset spring 30 is fixedly connected between the sliding block 29 and the sliding groove 24, the sliding block 29 and the control rod 27 are fixedly connected, and the movement track of the control rod 27 is determined and limited; Firstly, the torque sensor, also commonly known as a moment sensor, is a precision instrument for measuring various torques (rotational forces). Its core function is to convert the physical quantity of torque into a high-precision electrical signal output, thereby achieving accurate detection, monitoring and control of torque. The electro-hydraulic servo cylinder 40 is a kind of hydraulic actuator that realizes linear motion with high precision and high response speed by using an electro-hydraulic servo valve as the core control component and internally installing a position / speed / force sensor to form a closed-loop feedback. When the electro-hydraulic servo cylinder 40 is started, it moves the object connected to its output end by a certain distance. In this scheme, the two torque sensors and the controller controlling the electro-hydraulic servo cylinder 40 are electrically connected. The controller will only activate the electro-hydraulic servo cylinder 40 when the electrical signals emitted by the two torque sensors are not significantly different, thereby moving the control rod 27 a certain distance. During the movement of the moving rod 10, the control block 22, control shaft 33, and clamp rod 41 move together with the moving rod 10. Before the moving rod 10 comes into contact with the cable bundle, the clamp rod 41 has already come into contact with the cable bundle. At this time, the cable bundle will hinder the clamp rod 41 from moving with the moving rod 10. Under the obstruction of the cable bundle, not only will the control block 22, control shaft 33, and clamp rod 41 move to the left relative to the moving rod 10, but the clamp rod 41 will also open further. At this time, under the action of the cable bundle, when the clamp rod 41 just comes into contact with the cable bundle, the cable bundle, which is not bound by the aluminum foil tape, will be in a flower-like shape. (Refer to Appendix) Figure 7 As shown, when the clamping rod 41 abuts against the cable bundle, the upper and lower clamping rods 41 on the same control shaft 33 rotate at different angles. When the clamping rod 41 moves downward with the moving rod 10, when both the upper and lower clamping rods 41 abut against the aluminum foil tape, this area can be approximated as cylindrical. Therefore, the difference in rotation angle between the two clamping rods 41 on the upper and lower sides of the same control shaft 33 is not significant, that is, the difference in electrical signals emitted by the upper and lower torque sensors is not significant. At this time, the electro-hydraulic servo cylinder 40 is activated, which in turn drives the control rod 27 to move to the left a certain distance. At this time, the slide rod 28 moves out of the threaded groove 34, and the square rod 16 just enters the fixed frame 15 and is then stuck by the fixed frame 15. At this time, the moving rod 10 stops moving in the vertical direction until the isolation plate 7 abuts against the aluminum foil tape. At this time, the moving rod 10 is inserted into the cable bundle, and the moving rod 10 abuts against the aluminum foil tape.

[0016] A clamping assembly is installed on the outside of the movable plate 6. The clamping assembly includes a connecting block 26 fixedly installed on the upper side of the control rod 27. A round rod 21 is fixedly connected to the upper side of the connecting block 26. Two rotating shafts 17 are symmetrically rotatably connected to the outside of the movable rod 10. A rotating plate 18 is fixedly connected to the outside of the rotating shaft 17. An eccentric rod 19 is fixedly connected to the outside of the rotating plate 18. A telescopic plate 20 is rotatably connected to the outside of the eccentric rod 19. The telescopic plate 20 and the round rod 21 are rotatably connected. First, a buffer spring is fixedly installed inside the telescopic plate 20. During the movement of the control rod 27 relative to the moving rod 10, because the eccentric rod 19 and the rotating shaft 17 are in an eccentric state, the control rod 27 drives the round rod 21 to move via the connecting block 26. Under the restraining effect of the telescopic plate 20, this causes the rotating plate 18 to rotate around the rotating shaft 17, i.e., around... Figure 8From the perspective of the rotating plate 18, the upper rotating plate 18 rotates clockwise, and the lower rotating plate 18 rotates counterclockwise, that is, the two rotating plates 18 move towards each other, the two rotating plates 18 and the cable are in contact, and further clamping and fixing effect of the cable is formed, and the stability of the cable can be further improved.

[0017] In the present application, when the device is in use, the aluminum foil tape is wound outside the cable to ensure that the cable is firmly fixed, and then the aluminum foil tape region passes through the isolation plate 7, the hydraulic device 5 is started, the moving plate 6 and the isolation plate 7 are driven by the hydraulic device 5 to move towards each other until the isolation plate 7 and the aluminum foil tape are in contact. In the process, under the action of the rack 11, the gear 9 moving with the rotating rod 8 rotates, the rotating rod 8 rotates through the belt pulley assembly 14 to drive the rotating cylinder 12 to rotate, and the rotating cylinder 12 drives the moving rod 10 to move towards the isolation plate 7, that is, the upper moving rod 10 moves downward, and the lower moving rod 10 moves upward until the moving rod 10 is inserted into the cable bundle, and the moving rod 10 and the aluminum foil tape are in contact, which forms extrusion of the aluminum foil tape and clamping and fixing of the cable bundle and the aluminum foil tape, and the moving rod 10 and the aluminum foil tape are fixed by cooperation, which can not only prevent the cable from moving by stretching the outer shell 1, but also prevent the cable from moving too much due to the work of the inner shell 1, which affects the normal work of the circuit. During the movement of the moving rod 10, the control block 22, the control shaft 33 and the clamp rod 41 always move with the moving rod 10, and before the moving rod 10 and the cable bundle are in contact, the clamp rod 41 has been in contact with the cable bundle. At this time, under the hindering action of the cable bundle, not only will the clamp rod 41 be hindered from moving with the moving rod 10, but also the clamp rod 41 will be further opened. At this time, under the action of the cable bundle, when the clamp rod 41 just contacts the cable bundle, the upper and lower clamp rods 41 on the same control shaft 33 have different rotation angles. When the upper and lower clamp rods 41 are in contact with the aluminum foil tape, the difference between the rotation angles of the upper and lower clamp rods 41 on the same control shaft 33 is small, that is, the difference between the electric signals emitted by the upper and lower torque sensors is small. At this time, the electro-hydraulic servo cylinder 40 is started, and then drives the control rod 27 to move a distance to the left. At this time, the slide rod 28 moves out of the threaded groove 34, and the square rod 16 just enters the fixed frame 15 and is clamped by the fixed frame 15. At this time, the movement of the moving rod 10 in the vertical direction is stopped until the isolation plate 7 and the aluminum foil tape are in contact. At this time, the moving rod 10 is inserted into the cable bundle, and the moving rod 10 and the aluminum foil tape are in contact. In the process of moving the control rod 27 relative to the moving rod 10, the control rod 27 drives the round rod 21 to move through the connecting block 26, and under the restriction of the telescopic plate 20, the upper rotating plate 18 rotates clockwise and the lower rotating plate 18 rotates counterclockwise, that is, the two rotating plates 18 move towards each other, the two rotating plates 18 and the cable are in contact, and further clamping and fixing effect of the cable is formed, which can further improve the stability of the cable.
