[0030] First, the device in use, the compressor and transformer into the shell 1, and the compressor and transformer are fixed, can be fixed by tightening the bolt, then in the shell 1 respectively for the compressor and transformer installation protection device, such as: fuse, temperature sensor, safety cut-off valve, etc., can be real-time monitoring and protection of the compressor and transformer, to ensure that the transformer is running under safe electrical parameters, any "border" behavior will be timely to stop, to ensure that the compressor its mechanical system in the best state of operation, to avoid overheating, spark and even explosion due to mechanical failure, then the compressor pipe through the pipe connection port 4, with the compressor and transformer connected cable through the cable connection port 2, through the threaded hole and nut 37 on the locking screw 35, complete the installation and fixation operation of the sealing cover 3;

[0031] The cable connection port 2 is provided with a sealing assembly, the sealing assembly 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, a plurality of isolation plates 7 are fixedly installed on the side wall of the moving plate 6, the plurality of isolation plates 7 are arranged in a staggered manner, a rotating cylinder 12 is rotatably penetrated 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, the telescopic rod 13 is 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, the control rod 27 is fixedly connected with a sliding rod 28 on the outer side, a threaded groove 34 is formed in the rotating cylinder 12, the sliding rod 28 is slidably connected with the threaded groove 34, as shown in Figure 8 、 Figure 9 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 extends into the threaded groove 34 and is slidably connected with the threaded groove 34, a power assembly for rotating 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 rotating rod 8 is fixedly connected with a gear 9 on the side away from the moving plate 6, a rack 11 is fixedly installed in the cable connection port 2, the rack 11 is engaged with the gear 9.

[0032] During the electrical connection process, aluminum foil tape is wrapped around the outside of the cable (here, "cable" refers not to a single cable, but to all cables passing through cable connection port 2, i.e., the cable bundle) to ensure the cable is firmly fixed. Then, when clamping and fixing the cable, the aluminum foil tape area is passed through the isolation plate 7, and the hydraulic device 5 is activated. The hydraulic device 5 drives the moving plate 6 and the isolation plate 7 to move closer to each other until the isolation plate 7 and the aluminum foil tape come into contact. During this process, since the rack 11 is in a fixed state, the gear 9 that moves with the rotating rod 8 will rotate. The gear 9 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the rotating cylinder 12 to rotate through the 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 in a sliding connection with the moving plate 6 under the restriction of the telescopic rod 13. At the same time, the threaded groove 34 is divided into two sections, and the thread directions of the two sections of the threaded groove 34 are set in opposite directions. Therefore, the rotating cylinder 12 will drive the moving rod 10 to move closer to the isolation plate 7, i.e. Figure 6 From the perspective of the upper moving rod 10, the lower moving rod 10 moves downward and upward. During this process, the moving rod 10 also moves with the moving plate 6. That is, from the overall perspective, the upper moving rod 10 moves downward and to the right at the same time, and the lower moving rod 10 moves upward and to the right at the same time, until the moving rod 10 is inserted into the cable bundle. The moving rod 10 and the aluminum foil tape come into contact, which will squeeze the aluminum foil tape and form a clamping and fixing of the cable bundle and the aluminum foil tape. The fixing is achieved by the cooperation of the moving rod 10 and the aluminum foil tape. This not only prevents the cable from moving due to the strong stretching of the outer shell 1, but also prevents the cable from moving severely due to the operation of the outer shell 1 (for example, when the compressor is working, different pressures may cause the transport pipe to shift, and the transport pipe and the cable may come into contact, thus causing the cable to move). That is, the cable moving too far will affect the normal operation of the circuit.

[0033] The outer side of the moving rod 10 is provided with an automatic disconnecting assembly, the automatic disconnecting assembly comprises a control block 22 slidingly installed in a through groove 23, a control spring 31 is fixedly connected between the control block 22 and the through groove 23, the lower side of the control block 22 is fixedly connected with a control shaft 33 through a right-angle rod 32, two control plates 38 are rotatably connected to the outer upper and lower sides of the control shaft 33, a torsion spring 39 is fixedly connected between the two control plates 38 and the control shaft 33, a torque sensor is fixedly connected between the two control plates 38, clamping rods 41 are fixedly connected to the outer sides of the two control plates 38, an electro-hydraulic servo cylinder 40 is fixedly connected in the through groove 23, the control rod 27 is fixedly connected with the output end of the electro-hydraulic servo cylinder 40, the control rod 27 is fixedly connected with a square rod 16, the moving plate 6 is fixedly connected with a fixed frame 15, two sliding grooves 24 are opened in the inner side wall of the through groove 23, sliding blocks 29 are slidingly connected in the two sliding grooves 24, reset springs 30 are fixedly connected between the sliding blocks 29 and the sliding grooves 24, the sliding blocks 29 are fixedly connected with the control rod 27, and the movement track of the control rod 27 is determined and limited;

[0034] Firstly, the torque sensor, also commonly known as a moment sensor, is a kind of precision instrument for measuring various torques (rotational forces), and its core function is to convert the physical quantity of torque into a high-precision electrical signal output, so as to realize accurate detection, monitoring and control of torque,

[0035] The electro-hydraulic servo cylinder 40 is a kind of hydraulic actuator which realizes high-precision and high-response-speed linear motion by taking an electro-hydraulic servo valve as a core control element and internally arranging a position / speed / force sensor to form a closed-loop feedback, and when the electro-hydraulic servo cylinder 40 is started, the electro-hydraulic servo cylinder 40 will move the object connected with the output end of the electro-hydraulic servo cylinder 40 by a certain distance,

[0036] In the scheme, the two torque sensors and the controller for controlling the electro-hydraulic servo cylinder 40 are in an electrically connected state, and only when the difference between the electrical signals of the two torque sensors is small, the controller will start the electro-hydraulic servo cylinder 40, thereby driving the control rod 27 to move by a certain distance. During the movement of the moving rod 10, the control block 22, the control shaft 33 and the clamping rod 41 always move together with the moving rod 10. Before the moving rod 10 and the cable bundle abut against each other, the clamping rod 41 has abutted against the cable bundle. At this time, under the hindering action of the cable bundle, the clamping rod 41 will be hindered from moving together with the moving rod 10. At this time, under the hindering action of the cable bundle, not only will the control block 22, the control shaft 33 and the clamping rod 41 as a whole move to the left relative to the moving rod 10, but also the clamping rod 41 will be further opened. At this time, under the action of the cable bundle, when the clamping rod 41 just abuts against the cable bundle, the cable bundle which is not bound by the aluminum foil tape is in a flower-like shape. Referring to the drawings, Figure 7As shown, therefore, when the clamping rods 41 abut against the cable bundle, the two clamping rods 41 on the same control shaft 33 have different rotation angles, and when the clamping rods 41 move downward along with the moving rod 10, the area where the two clamping rods 41 abut against the aluminum foil tape is approximately cylindrical, and the difference in the rotation angles of the two clamping rods 41 on the same control shaft 33 is small, that is, the difference in the electrical signals emitted by the two torque sensors is small, at which time the electro-hydraulic servo cylinder 40 is activated, thereby driving the control rod 27 to move to the left by a distance, at which time the slide rod 28 moves out of the threaded groove 34, and the square rod 16 just enters the fixed frame 15, thereby being clamped by the fixed frame 15, at which time the movement of the moving rod 10 in the vertical direction is stopped until the isolation plate 7 abuts against the aluminum foil tape, at which time the moving rod 10 is inserted into the cable bundle, and the moving rod 10 abuts against the aluminum foil tape.

[0037] The moving plate 6 is provided with a clamping assembly, which comprises a connecting block 26 fixedly installed on the upper side of the control rod 27, a circular rod 21 fixedly connected to the upper side of the connecting block 26, two rotating shafts 17 symmetrically and rotatably connected to the outer side of the moving rod 10, rotating plates 18 fixedly connected to the outer side of the rotating shafts 17, eccentric rods 19 fixedly connected to the outer side of the rotating plates 18, and telescopic plates 20 rotatably connected to the outer side of the eccentric rods 19.

[0038] First, the telescopic plate 20 is provided with a buffer spring fixedly installed therein. During the movement of the control rod 27 relative to the moving rod 10, since the eccentric rod 19 and the rotating shaft 17 are in an eccentric state, during the movement of the control rod 27, the control rod 27 drives the circular rod 21 to move through the connecting block 26, and under the limiting action of the telescopic plate 20, drives the rotating plate 18 to rotate around the rotating shaft 17, that is, the rotating plate 18 rotates in a clockwise direction, and the rotating plate 18 rotates in a counterclockwise direction, that is, the two rotating plates 18 move towards each other, and abut against the cable, thereby further clamping and fixing the cable, and further improving the stability of the cable. Figure 8

[0039] ​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 area is passed through the isolation plate 7, the hydraulic equipment 5 is started, the hydraulic equipment 5 drives the moving plate 6 and the isolation plate 7 to move towards each other until the isolation plate 7 and the aluminum foil tape abut, in the process, under the action of the rack 11, the gear 9 moving with the rotating rod 8 will rotate, the gear 9 drives the rotating rod 8 to rotate, the rotating rod 8 drives the rotating cylinder 12 to rotate through the belt pulley assembly 14, the rotating 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, the moving rod 10 and the aluminum foil tape abut, and the extrusion of the aluminum foil tape is formed, and the clamping and fixing of the cable bundle and the aluminum foil tape are formed, and the fixing is realized by the cooperation of the moving rod 10 and the aluminum foil tape, 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 will affect the normal work of the circuit;

[0040] 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, before the moving rod 10 abuts against the cable bundle, the clamp rod 41 has abutted against 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 will the clamp rod 41 be further opened, and at this time, under the action of the cable bundle, when the clamp rod 41 just abuts against the cable bundle, the upper and lower clamp rods 41 on the same control shaft 33 have different rotation angles, when the clamp rod 41 moves downward with the moving rod 10, when the upper and lower clamp rods 41 abut against 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 not large, that is, the difference between the electrical signals emitted by the upper and lower torque sensors is not large, 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 abut, at this time, the moving rod 10 is inserted into the cable bundle, and the moving rod 10 abuts against the aluminum foil tape;

[0041] During the movement of 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, under the limiting action 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 abut against the cable, and further clamping and fixing effect of the cable is formed, which can further improve the stability of the cable.
