[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] Please refer to 1-8, a special low-temperature and corrosion-resistant cable for ships, comprising a cable 1 and two fixing rings 2, the two fixing rings 2 being respectively arranged on both sides of the wall, a plurality of heat-conducting tubes 21 being slidably arranged on the two fixing rings 2, the plurality of heat-conducting tubes 21 being in contact with the cable 1, and the heat-conducting tubes 21 on the two fixing rings 2 being in cooperative contact, and a cooling liquid being arranged in the plurality of heat-conducting tubes 21; and a locking assembly is also included, which is used to clamp and seal between the fixing ring 2 and the cable 1, and at the same time make the heat-conducting tube 21 slide and fit with the cable 1, after the cable 1 is laid, the heat-conducting tubes 21 on the fixing rings 2 on both sides are in contact with each other, and at the same time the heat-conducting tube 21 and the cable 1 are in contact, and when the temperature difference between the two sides of the wall is large, the cooling liquid in the heat-conducting tube 21 is used to The temperature on both sides of the fixing point of the cable 1 is adjusted, and the area covered by the heat pipe 21 on the cable 1 is formed as a transition area, so as to avoid a large temperature difference on both sides of the wall, directly act on the cable 1, and reduce the stress on the cable 1 under the temperature difference, so as to avoid the phenomenon of excessive aging at the connection between the cable 1 and the wall, and improve the service life of the cable 1; and by making the heat pipes 21 on the two fixing rings 2 contact, the temperature from both sides of the wall can be better neutralized, thereby improving the efficiency of regulating the temperature of the fixing point of the cable 1 and the wall; the coolant has a smaller specific heat capacity than water, and can absorb the temperature on both sides of the wall to which the cable 1 is subjected more quickly, and neutralize it, thereby reducing the temperature difference on both sides of the wall to which the cable 1 is subjected.

[0034] Specifically, a tensioning block 22 is fixedly provided on the heat conducting tube 21, a threaded ring 3 is fixedly provided on the fixed ring 2, a sliding frame 32 is slidably provided on the threaded ring 3, a cross bar 33 is fixedly provided on the sliding frame 32, an inclined groove 23 is provided on the tensioning block 22, and the cross bar 33 is slidably provided in the inclined groove 23. The tensioning block 22 is made of copper. When the sliding frame 32 slides, the tensioning block 22 slides with the heat conducting tube 21 through the mutual cooperation between the cross bar 33 and the inclined groove 23, so that the heat conducting tube 21 is fitted with the cable 1. After the fixing rings 2 on both sides are installed, the cable 1 can be slid to adjust the fixed position of the cable 1, and then the heat pipe 21 can be fitted with the cable 1, so that the cable 1 is more portable when laying; and copper has good thermal conductivity. Under the thermal conductivity of the tensioning block 22, the tensioning blocks 22 on both sides of the wall guide the temperature of both sides of the wall to the heat pipe 21 and the coolant, and neutralize it with the coolant, so as to better adjust the temperature difference of the cable 1 in the area where the heat pipe 21 is fitted.

[0035] In an embodiment further provided by the present invention, the locking assembly includes an abutment ring 31 threadedly connected to the threaded ring 3, the abutment ring 31 abuts against the sliding frame 32, and when the abutment ring 31 rotates, under the action of the threaded ring 3, it translates, abuts against the sliding frame 32, and pushes the sliding frame 32 to slide, so that the tensioning block 22 slides with the heat pipe 21, and the heat pipe 21 is in contact with the cable 1, thereby adjusting the temperature difference of the cable 1 in the contact area.

[0036] Furthermore, an arc block 4 is slidably provided on the sliding frame 32, and a sealing gasket is fixedly provided on the arc block 4, and the cable 1 is clamped and sealed by the sealing gasket. When the sliding frame 32 slides to make the heat pipe 21 fit the cable 1, the arc block 4 slides to clamp and fix the cable 1, and the clamping position is sealed by the sealing gasket on the arc block 4 to prevent water vapor from entering the hole on the wall for laying the cable 1, causing the fixing point of the cable 1 and the wall to be in a wet state for a long time, causing corrosion.

[0037] Furthermore, a first spring 41 is provided between the arc block 4 and the sliding frame 32, and both ends of the first spring 41 are fixedly connected to the arc block 4 and the sliding frame 32 respectively. During the sliding of the sliding frame 32, the arc block 4 slides to stretch the first spring 41 and clamp the cable 1. When the sliding frame 32 has not yet slid, under the action of the first spring 41, the arc block 4 does not clamp the cable 1, so that after the fixing ring 2 is fixed, the cable 1 can be slid to adjust the fixed position of the cable 1, which facilitates the installation of the fixing ring 2 and the laying of the cable 1.

[0038] In an embodiment further provided by the present invention, a rotating tube 5 is rotatably provided on one of the fixing rings 2, a fixing rod 6 is fixedly provided on the other fixing ring 2, an arc groove 53 is provided on the rotating tube 5, and a protrusion 61 is fixedly provided on the fixing rod 6. The protrusion 61 is slidably matched with the arc groove 53. When the fixing rings 2 on both sides of the wall are inserted into the reserved holes on both sides of the wall, the fixing rod 6 is inserted into the rotating tube 5, and the protrusion 61 is inserted into the arc groove 53. When the two fixing rings 2 are close to each other, under the action of the protrusion 61 and the arc groove 53, the rotating tube 5 rotates to make the fixing ring 2 fit with the reserved hole in the wall, thereby improving the efficiency and portability of the installation of the fixing ring 2, and is suitable for walls of various thicknesses.

[0039] In the embodiment provided by the present invention, a friction plate 51 is slidably provided on the rotating tube 5, and the friction plate 51 is in frictional contact with the abutment ring 31. After the fixed ring 2 is fitted with the hole reserved in the wall, the abutment ring 31 rotates and translates. After the abutment ring 31 is in frictional contact with the friction plate 51, the rotation of the rotating tube 5 is restricted. The two fixed rings 2 can be fixed by the fixing rod 6 and the protrusion 61 and the inclined groove 23 on the rotating tube 5, so that the fixed ring 2 is in abutment with the hole reserved in the wall, thereby avoiding the need to drill a hole in the wall when fixing the fixed ring 2, thereby greatly improving the efficiency of laying the cable 1.

[0040] Specifically, a second spring 52 is provided between the friction plate 51 and the rotating tube 5, and two ends of the second spring 52 are fixedly connected to the friction plate 51 and the rotating tube 5 respectively. After the abutment ring 31 abuts against the friction plate 51, the abutment ring 31 continues to be rotated to compress the second spring 52, thereby ensuring the abutment between the abutment ring 31 and the friction plate 51. After the friction plate 51 is used for a long time, it will be worn. The second spring 52 can compensate for the friction plate 51, so that the friction plate 51 can still abut against the abutment ring 31, thereby ensuring the fixing effect on the sliding tube.

[0041] In the solution further provided by the present invention, inclined surfaces are provided on the fixing ring 2 and the arc block 4. The fixing ring 2 abuts against the reserved hole in the wall through the inclined surface, thereby improving the sealing between the fixing ring 2 and the wall and preventing water vapor from entering the reserved hole on the wall from between the fixing ring 2 and the wall. The inclined surface on the arc block 4 can not only increase the sealing between the arc block 4 and the cable 1, but also improve the clamping effect of the arc block 4 on the cable 1.

[0042] When laying the cable 1, the fixing ring 2 is inserted into the reserved holes on both sides of the wall, and the fixing rod 6 is inserted into the rotating tube 5, and the protrusion 61 is inserted into the arc groove 53, and then the inclined surface of the fixing ring 2 is abutted against the wall. During the abutting process, under the action of the protrusion 61 and the arc groove 53, the rotating tube 5 is rotated. After the fixing ring 2 abuts against the wall, the cable 1 is slid to adjust the fixed position of the cable 1, and then the abutting ring 31 on the fixing rings 2 on both sides is rotated. During the rotation process, the abutting ring 31 is threadedly connected with the threaded ring 3 and moves horizontally, abuts against the sliding frame 32, and pushes the sliding frame 32 to slide. During the sliding process of the sliding frame 32, under the action of the cross bar 33 and the inclined groove 23, the tensioning block 22 Slide into the fixing ring 2, and make the heat-conducting tube 21 slide and fit with the cable 1. After the heat-conducting tube 21 fits with the cable 1, the heat-conducting tubes 21 on the fixing rings 2 on both sides also contact each other, and in the sliding process, the inclined surface of the arc block 4 abuts against the fixing ring 2, and under the abutment action, the first spring 41 is stretched, and the cable 1 is clamped by sliding, and the sealing gasket on the arc block 4 fits with the cable 1 to seal the cable 1 and the fixing ring 2, and the abutment ring 31 abuts against the friction plate 51, and the second spring 52 is compressed to make the friction plate 51 unable to rotate, thereby locking the rotating tube 5 with the fixing rod 6, thereby fixing the fixing rings 2 on both sides of the wall, and the laying of the cable 1 is completed.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
