[0002] For some cables, such as power cables, operating in a humid environment or even in an environment of short-term immersion or long-term soaking in water is very likely to cause the weakening of the insulation layer function, resulting in the breakdown of the cable insulation layer, or the oxidation of the cable after being affected by moisture to generate impurities (such as copper oxide or copper green), leading to an increase in resistance, poor electrical conductivity, and even heating and ignition, seriously affecting the safe operation of the line. From the perspective of engineering practical applications, in some projects, after the cable is laid, it is not filled in time, and the outdoor cable may be damaged by external forces, resulting in the damage or even breakage of the insulation layer, and it is easy to cause the cable to be soaked in water due to reasons such as rainwater or groundwater deposition.

[0003] When the cable is soaked in water, it is necessary to carry out dehumidification treatment in time. In related technologies, there is a way to dehumidify the cable by using an air pump to extract the water vapor inside the cable.

[0037] As Figure 1 shown, a cable dehumidification device provided by an embodiment of the present utility model includes a cable docking mechanism 100, a dehumidification mechanism 200, and a pipeline 300. Among them, the cable docking mechanism 100 is used to connect the cable 10 to be dehumidified, the pipeline 300 is used to connect the cable docking mechanism 100 and the dehumidification mechanism 200, and the dehumidification mechanism 200 can pump air, so as to suck the water vapor in the cable 10 to be dehumidified, achieving the purpose of dehumidification.

[0038] As Figures 2 to 4 shown, the cable docking mechanism 100 includes a housing 110, a fixing plate 120, a sealing member 130, and a movable plate 140.

[0039] As Figure 4 shown, the housing 110 is provided with an installation cavity 111, an opening 112 communicating with the installation cavity 111, and an air extraction port 113 communicating with the installation cavity 111.

[0042] Among them, the outer housing 110 is made of rigid materials such as steel, iron, ceramics, etc.

[0043] Combined Figure 1 with Figure 3 , furthermore, the outer end of the air extraction port 113 is connected with a connector 1131, and this connector 1131 is used to connect the pipeline 300.

[0044] As Figure 4 shown, the fixing plate 120 is arranged in the installation cavity 111, and the fixing plate 120 is provided with a first avoidance hole 121 communicating with the air extraction port 113.

[0045] Specifically, the fixing plate 120 is fixed to the cavity wall of the installation cavity 111, and the fixing plate 120 surrounds to form a first avoidance hole 121. The first avoidance hole 121 is arranged opposite to the cover plate 115 and communicates with the air extraction port 113.

[0046] More specifically, the fixing plate 120 is of an annular structure. The outer side of the fixing plate 120 is fixed to the cavity wall of the installation cavity 111, and the central hole of the fixing plate 120 is the first avoidance hole 121.

[0047] Among them, the fixing plate 120 is made of rigid materials such as steel, iron, ceramics, etc.

[0048] Combined Figure 2 with Figure 4 , the sealing member 130 is made of an elastic material. The sealing member 130 is arranged in the installation cavity 111 and is located on the side of the fixing plate 120 close to the opening 112. One end of the elastic sealing member 130 abuts against the fixing plate 120, and the elastic sealing member 130 surrounds to form an installation channel 131 communicating with the first avoidance hole 121.

[0049] Specifically, the sealing member 130 is made of an elastic material such as elastic rubber. The sealing member 130 surrounds to form an installation channel 131. One end of the sealing member 130 abuts against the side of the fixing plate 120 close to the opening 112, and makes the installation channel 131 communicate with the first avoidance hole 121, so that the installation channel 131 communicates with the air extraction port 113.

[0050] In some other embodiments, the sealing member 130 is made of a flexible material such as flexible rubber materials or fiber materials.

[0051] Combined Figure 2 with Figure 4, the movable plate 140 is disposed in the installation cavity 111 in a position - adjustable manner and is located on the side of the elastic seal 130 away from the fixed plate 120. The movable plate 140 is provided with a second avoidance hole 141 communicating with the installation passage 131.

[0052] Specifically, the movable plate 140 is disposed in the installation cavity 111, is spaced and oppositely disposed with respect to the fixed plate 120. The movable plate 140 is located on the side of the fixed plate 120 away from the air extraction port 113, and the movable plate 140 is located on the side of the elastic seal 130 away from the fixed plate 120. Moreover, the movable plate 140 is surrounded to form a second avoidance hole 141 communicating with one end of the installation passage 131 away from the first avoidance hole 121.

[0053] More specifically, the movable plate 140 is of an annular structure, and the central hole of the movable plate 140 is the second avoidance hole 141.

[0054] Among them, the movable plate 140 is made of a rigid material, such as steel, iron, ceramic, etc.

[0055] In the cable docking mechanism 100 of the present utility model, the air extraction port 113 on the outer housing 110 can be communicated with the intake end of the air extraction pump 210 of the dehumidification mechanism 200 through a pipeline 300. The end of the cable to be dehumidified 10, that is, the end infiltrated with water vapor, can pass through the second avoidance hole 141 and be disposed in the installation passage 131. The movable plate 140 can be operated to move towards the fixed plate 120 to squeeze the seal 130, so that the seal 130 is compressed and fills between the outer side wall of the cable to be dehumidified 10 and the cavity wall of the installation cavity 111, so that the seal 130 abuts against the cavity wall of the installation cavity 111 and the outer side wall of the cable to be dehumidified 10 respectively, thereby realizing sealing. In this way, when the air extraction pump 210 performs air extraction, the suction force provided by the air extraction pump 210 will act concentratedly on the water vapor inside the cable to be dehumidified 10, improving the efficiency of the water vapor being extracted, and thus improving the dehumidification efficiency. In addition, the cable docking mechanism 100 of the present utility model can realize the docking of cables with different outer diameters.

[0056] Combined Figure 2 with Figure 3 , in some embodiments, the cable docking mechanism 100 further includes an adjusting rod 151 and an adjusting member 152. The movable plate 140 is provided with a through - hole. One end of the adjusting rod 151 is connected to the fixed plate 120, the other end of the adjusting rod 151 passes through the through - hole, and the adjusting member 152 is movably connected to the adjusting rod 151 and abuts against the side of the movable plate 140 away from the fixed plate 120. The adjusting member 152 can be operably moved along the axial direction of the adjusting rod 151.

[0057] It can be understood that when the adjusting member 152 is operated to move axially along the adjusting rod 151 and approach the fixed plate 120, the adjusting member 152 will squeeze the movable plate 140, causing the movable plate 140 to move toward the fixed plate 120 and squeeze the seal 130.

[0058] Specifically, the adjusting rod 151 is provided with a threaded section that passes through the through hole, and the adjusting member 152 is provided with a threaded hole, and the threaded section passes through the threaded hole. In this way, by rotating the adjusting member 152, the adjusting member 152 can be moved axially along the adjusting rod 151, thereby driving the movable plate 140 to move toward the fixed plate 120 and squeeze the seal 130.

[0059] It can be understood that when the adjusting member 152 is rotated away from the fixed plate 120, the movable plate 140 will also loosen, so that the seal 130 is restored to facilitate the subsequent extraction of the cable.

[0060] Combined Figure 2 with Figure 4 , further, the fixed plate 120 is provided with a connection hole 122, the seal 130 is provided with a through hole corresponding to the connection hole 122, and the through hole on the movable plate 140 corresponds to the through hole; the adjusting rod 151 is fixedly passed through the connection hole 122, and the adjusting rod 151 passes through the through hole and the through hole to extend out, and the adjusting member 152 is sleeved outside the adjusting rod 151 and abuts against the side of the movable plate 140 away from the fixed plate 120.

[0061] Among them, the connection hole 122 is a threaded hole, and the threaded section passes through the connection hole 122.

[0062] It should be noted that the number of the adjusting components composed of the adjusting rod 151 and the adjusting member 152 is multiple groups, and the multiple groups of adjusting components are arranged at intervals along the circumferential direction of the installation channel 131.

[0063] As Figure 2 shown, in some embodiments, the cable docking mechanism 100 further includes a cable fixing component, and the cable fixing component is arranged on the outer housing 110, and the cable fixing component is used for clamping or loosening the cable to be dehumidified 10.

[0064] Specifically, the cable fixing component includes multiple groups of cable fixing units 160, and the multiple groups of cable fixing units 160 are arranged around the opening 112; the cable fixing unit 160 includes a connection block 161 fixed on the outer housing 110 and a resisting member 162 passing through the connection block 161, and the resisting ends of the resisting members 162 of the multiple groups of cable fixing units 160 can be operably gathered or dispersed.

[0065] It can be understood that when the abutting ends of the abutting members 162 of multiple groups of cable fixing units 160 gather together, the cable 10 to be dehumidified can be clamped, and when the abutting ends of the abutting members 162 of multiple groups of cable fixing units 160 spread apart, the cable 10 to be dehumidified can be released. It can be understood that the cable fixing assembly can further fix the cable 10 to be dehumidified and reduce the risk of loosening of the cable 10 to be dehumidified.

[0066] In some embodiments, the abutting end of the abutting member 162 is a flexible part. In this way, the risk of the cable 10 to be dehumidified being damaged by pressure can be reduced. Among them, the abutting end of the abutting member 162 is made of rubber material.

[0067] Combined with Figure 3 and Figure 4 , in some embodiments, at one end of the outer housing 110 far away from the opening 112, that is, on the cover plate 115, there is also an exhaust port 114, and a valve 1141 is connected at the exhaust port 114.

[0068] It can be understood that before the cable 10 to be dehumidified is inserted into the cable docking mechanism 100, the valve 1141 is opened. In this way, it can be ensured that during the insertion of the cable 10 to be dehumidified, the gas in the outer housing 110 can be discharged in time, facilitating the insertion of the cable 10 to be dehumidified. After the cable 10 to be dehumidified is inserted, the valve 1141 is closed again.

[0069] It should be noted that a first sensor 170 and a second sensor 180 are also provided on the outer housing 110. Among them, the first sensor 170 integrates temperature and humidity detection functions and is used to detect the temperature and humidity inside the outer housing 110; the second sensor 180 is a pressure sensor and is used to detect the air pressure inside the outer housing 110.

[0070] As Figure 2 shown, it should be noted that in order to facilitate the transportation of the cable docking mechanism 100, a handle 190 is also provided on the outer housing 110.

[0071] Combined with Figure 1 and Figure 5 , the dehumidification mechanism 200 includes an air extraction pump 210. One end of the pipeline 300 is connected to the air extraction port 113, and the other end is connected to the intake end of the air extraction pump 210. When the air extraction pump 210 extracts air, the suction provided by the air extraction pump 210 will act concentratedly on the water vapor inside the cable 10 to be dehumidified, so as to suck out the water vapor inside the cable 10 to be dehumidified, thereby achieving the purpose of cable dehumidification.

[0072] Furthermore, the dehumidification mechanism 200 further includes a dehumidifying member 220. The dehumidifying member 220 is connected to the intake end of the air extraction pump 210, and the end of the pipeline 300 far away from the cable docking mechanism 100 is connected to the dehumidifying member 220.

[0073] Specifically, the dehumidifying member 220 is a tank body internally filled with a desiccant, a water absorbent or a condensation module. The inlet of the tank body is communicated with one end of the pipeline 300 far away from the cable docking mechanism 100, and the outlet of the tank body is communicated with the air inlet end of the air extraction pump 210. When the air extraction pump 210 sucks the water vapor in the cable, the water vapor will be separated by the dehumidifying member 220.

[0074] Further, the dehumidifying mechanism 200 further includes an air tank 230. The air tank 230 is communicated with the exhaust end of the air extraction pump 210. The air extraction pump 210 can discharge the gas into the air pipe so as to balance the air pressure in the air extraction pump 210.

[0075] Further, the air extraction pump 210 is arranged on the air tank 230, and the bottom of the air tank 230 is provided with traveling wheels 240. In this way, the movement of the entire dehumidifying mechanism 200 can be facilitated.

[0076] Further, a handrail 250 is arranged on the air tank 230 or the air extraction pump 210.

[0077] Combined with Figures 1 to 5 , the specific working process of the cable dehumidifying device of the present utility model is as follows:

[0078] First, open the valve 1141 to ensure that the gas in the outer housing 110 can be discharged in time during the process of loading the cable, facilitating the insertion of the cable; then, pass the cable through the second avoidance hole 141 of the movable plate 140 and insert it into the installation channel 131 of the seal 130; then, adjust the position of the adjusting member 152 so that the adjusting member 152 pushes the movable plate 140 to move towards the fixed plate 120 and presses the seal 130, so that the seal 130 is compressed and fills between the outer side wall of the cable to be dehumidified 10 and the wall of the installation cavity 111, thereby realizing sealing; then, use the cable fixing unit 160 to further clamp and fix the cable to reduce the risk of the cable sliding off; after that, use the pipeline 300 to connect the cable docking mechanism 100 and the dehumidifying mechanism 200; then, close the valve 1141 to ensure that the dehumidifying work is carried out in a sealed space; after that, start the dehumidifying work. At this time, the air extraction pump 210 starts to work, pumping the moist air generated in the cable due to soaking water through the pipeline 300 into the dehumidifying member 220, and the separated air enters the air tank 230.

[0079] In the cable dehumidification device of the present utility model, at the end of the cable 10 to be dehumidified, that is, the end where water vapor seeps in, can pass through the second avoidance hole 141 and be disposed in the installation channel 131. The movable plate 140 can be operated to move towards the fixed plate 120 to squeeze the seal 130, so that the seal 130 is compressed and fills between the outer wall of the cable 10 to be dehumidified and the wall of the installation cavity 111, thereby enabling the seal 130 to abut against the wall of the installation cavity 111 and the outer wall of the cable 10 to be dehumidified respectively, thus achieving sealing. In this way, when the air pump 210 pumps air, the suction force provided by the air pump 210 will act concentratedly on the water vapor inside the cable 10 to be dehumidified, improving the efficiency of extracting the water vapor, and thus improving the dehumidification efficiency. In addition, the cable docking mechanism 100 of the present utility model can achieve docking of cables with different outer diameters.
