Description

Technical Field

[0001] This utility model relates to the field of waterproof cable joint technology, and in particular to an integrated waterproof protective cover for cable joints used in power construction. Background Technology

[0002] In the field of power construction, waterproofing of cable joints is a key aspect of ensuring the safety of power transmission. In existing technologies, waterproofing of cable joints is achieved through physical sealing using heat shrink tubing, tape wrapping, or rigid sealing covers. These structures can form a seal through heating and shrinking or extrusion during initial installation, but their sealing performance is highly dependent on the operational precision of the construction personnel, and heat shrink materials are prone to cracking due to ultraviolet aging or mechanical stress, leading to waterproofing failure.

[0003] Therefore, existing waterproof protection for cable joints suffers from problems such as rigid sealing structures that cannot dynamically adapt to cable outer diameter deviations, gaps easily appearing at the sealing interface when the cable undergoes slight deformation due to thermal expansion and contraction, and creeping of traditional sealing materials under long-term cable tension, leading to a decrease in sealing pressure. To address these issues, an integrated waterproof protective cover for cable joints in power construction is proposed. This cover employs an airbag inflation and expansion filling method, using gas pressure to adapt to the cable outer diameter, forming a gapless seal that effectively prevents liquid intrusion. The annular airbag structure and drainage micropores work synergistically to both expel internal moisture and prevent external liquid backflow through air pressure balance, thus providing waterproof protection for the cable joint. Utility Model Content

[0004] In order to overcome the problems that traditional cable joints have in daily use, such as rigid sealing structures that cannot dynamically adapt to cable outer diameter deviations, gaps easily appearing at the sealing interface when the cable undergoes slight deformation due to thermal expansion and contraction, and traditional sealing materials prone to creep under long-term cable tension, leading to a decrease in sealing pressure.

One side of the moving block 108 is provided with a locking block 109. One side of the locking block 109 is provided with a rubber ring 110. The rubber ring 110 connects multiple sets of locking blocks 109.

[0023] Please see Figure 4 and Figure 5 In this embodiment, the locking assembly includes a worm gear 201 and a connecting plate 202. The worm gear 201 is provided on the inner side of the fixed base 107 and is rotatably connected to the cover 1. The connecting plate 202 is provided on one side of the worm gear 201. The locking assembly also includes a sliding groove 203 and a slider 204. The sliding groove 203 is provided on one side of the connecting plate 202. Multiple sets of sliding grooves 203 are provided. The slider 204 is provided on the inner side of the sliding groove 203 and is slidably connected to the sliding groove 203. The locking assembly also includes a connecting rod 205. The connecting rod 205 is provided on one side of the slider 204 and is rotatably connected to the moving block 108. In use, the worm gear 201 rotates to drive the connecting plate 202 to rotate. The rotation of the connecting plate 202 is used to fix the position of the fixed base 107, so that the slider 204 slides along the inner side of the sliding groove 203, thereby driving the moving block 108 to move linearly.

[0024] The drive assembly includes a connecting seat 301 and a worm gear 302. The connecting seat 301 is disposed on the outer side of the fixed seat 107, and the worm gear 302 is disposed on the inner side of the connecting seat 301. The worm gear 302 is meshed with a worm wheel 201. The drive assembly also includes a first bevel gear 303 and a second bevel gear 304. The first bevel gear 303 is disposed on the outer side of the worm gear 302 and is keyway connected to the worm gear 302. The second bevel gear 304 is disposed on the outer side of the connecting seat 301, and the first bevel gear 303 and the second bevel gear 304 are meshed with each other. The drive assembly also includes a rotating shaft. 305 and handle 306, the inner side of the second bevel gear 304 is provided with a rotating shaft 305, the rotating shaft 305 and the second bevel gear 304 are connected by a keyway, and one end of the rotating shaft 305 is provided with a handle 306. In use, rotating the handle 306 drives the rotating shaft 305 to rotate, the rotating shaft 305 drives the second bevel gear 304 to rotate, the second bevel gear 304 drives the first bevel gear 303 to rotate, the first bevel gear 303 drives the worm gear 302 to rotate, and the worm gear 302 drives the worm wheel 201 to rotate.

[0025] During operation, the cover 1 is first placed over the end of the cable 2 to be protected, allowing the cable 2 to pass through the annular tube 101 and airbag 105 inside the cover 1. The operator rotates the handle 306 of the drive assembly, causing the rotating shaft 305 and the second bevel gear 304 to rotate synchronously. The second bevel gear 304 meshes with and drives the first bevel gear 303, which in turn drives the worm gear 302 to rotate. The worm gear 302 meshes with the worm wheel 201 of the locking assembly, driving the worm wheel 201 to rotate within the fixed base 107. The worm gear 201 drives the connecting plate 202 to rotate synchronously. When the connecting plate 202 rotates, the multiple sets of sliding grooves 203 on its surface drive the slider 204 to move radially through sliding engagement. The slider 204 pulls the moving block 108 to slide linearly in the fixed seat 107 through the connecting rod 205. The multiple sets of moving blocks 108 synchronously push the locking block 109 to converge towards the center, squeezing the rubber ring 110 to produce radial deformation, thereby tightly fixing the cover 1 to the surface of the cable 2 with different outer diameters, realizing adaptive locking.

[0026] After the fixing is completed, the operator opens the pipe cover 103 and injects compressed gas into the annular pipe 101 through the air nozzle 102. The gas is introduced into the airbag 105 through the connecting pipe 104, causing the annular airbag 105 to expand and fill the gap between the cover 1 and the cable 2. The annular structure of the airbag 105 dynamically fits the outer contour of the cable 2 to form a gapless sealing layer, effectively preventing external liquid from entering. At the same time, multiple sets of drainage micro-holes 106 opened on the side of the cover 1 continuously discharge the condensed moisture inside through capillary action to prevent water vapor from accumulating. When external liquid attempts to backflow through the drainage micro-holes 106, the air pressure inside the airbag 105 and the capillary pressure of the drainage micro-holes 106 are balanced to prevent liquid from entering and ensure that the cable joint is in a dry ring.

[0027] If the locking component becomes loose due to thermal expansion and contraction of the cable during long-term use, the handle 306 can be rotated in the opposite direction to drive the worm gear 302 to reverse the worm wheel 201, causing the moving block 108 to slide outward, and the locking block 109 to release the rubber ring 110, thus readjusting the fixed position.

[0028] Through the above steps, multiple sets of moving blocks 108 linearly move to drive multiple sets of locking blocks 109 linearly move. The locking blocks 109 linearly move and squeeze the rubber ring 110, fixing the waterproof protective cover to the end of the cable 2. It can adapt to cables of different sizes. The tube cap 103 is used to close and open the air nozzle 102. Gas is injected into the annular tube 101 through the air nozzle 102. The gas is introduced into the airbag 105 through the annular tube 101 along the connecting tube 104. The airbag 105 is filled with gas and expands. The airbag 105 expands and fills the gap between the cable 2 and the cover 1, preventing liquid from reaching the cable end. The drainage micro-holes 106 are used to drain the moisture and water inside the cover 1, thereby waterproofing the cable end.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
