Description

Technical Field

[0001] This invention relates to the field of cable branch box technology, specifically a fiberglass power cable branch box. Background Technology

[0002] A cable distribution box is an outdoor or indoor electrical device used in power distribution networks. Its main function is to branch the main cable into multiple branch cables to achieve power distribution and transfer. It is usually composed of a shell, insulating sleeve, cable joint, grounding protection device, and internal connecting busbars. It features a compact structure and convenient installation. Distribution boxes are widely used in urban residential areas, industrial parks, commercial complexes, and temporary power supply scenarios. They can effectively reduce cable usage and construction costs, and improve power supply reliability. They can be equipped with load switches, fuses, and other protective components. Some models also support ring network power supply, so as to quickly isolate and restore power supply to non-faulty sections in the event of a fault. They are an indispensable node device in modern power distribution networks.

[0003] Currently, existing cable distribution boxes have poor heat dissipation performance due to their enclosed interior and dense wiring, which may lead to heat accumulation inside.

Simultaneously, as the push plate moves, it drives the second piston rod to move inside the L-shaped air cylinder, causing the first piston rod to drive the second rack to move. This allows the second rack to rotate via the fifth gear, enabling the first rack to drive the first frame to move. The first and second frames can then move up and down alternately, cleaning the inner and outer surfaces of the filter screen and completing the synchronous cleaning of the cable branch box and the inside of the filter screen.

The push plate 38 is slidably inserted into the top of the guide base plate 37, and the fourth rack 36 is symmetrically fixedly installed at the bottom of the push plate 38. When the push plate 38 is displaced, it can remove impurities accumulated in the heat dissipation holes inside the cable branch box 3.

[0034] like Figure 8 The linkage device 23 includes a splash-proof cavity 39, a first piston rod 40, a fifth gear 41, a protective cavity 42, an L-shaped air cylinder 43, and a second piston rod 44. The splash-proof cavity 39 is fixedly installed at the top of the protective cavity 42. The L-shaped air cylinder 43 is fixedly installed inside the splash-proof cavity 39 and the protective cavity 42. The second piston rod 44 is slidably inserted into the top of the L-shaped air cylinder 43. The first piston rod 40 is slidably inserted into the bottom of the L-shaped air cylinder 43. The fifth gear 41 is rotatably installed at the bottom of the inner part of the protective cavity 42. The protective cavity 42 wraps around the outer ring of the first rack 15 and the second rack 20, so that the first rack 15, the second rack 20, and the fifth gear 41 can be protected.

[0035] The feed chamber 18 is fixedly installed on both sides of the bottom of the cable branch box 3. The semiconductor condenser 14 is fixedly installed inside the feed chamber 18 away from the second frame 19. The first rack 15 and the second rack 20 respectively mesh with the fifth gear 41. The second piston rod 44 is connected to the end of the push plate 38 away from the fourth rack 36. The guide base plate 37 is symmetrically fixedly installed on both sides inside the cable branch box 3, and the guide base plate 37 is located above the feed chamber 18. The fourth gear 28 meshes with the third rack 35. The bottom end of the connecting rope 34 is connected to the outer ring of the winding shaft 5. The worm gear 9 meshes with the worm 12. The second gear 7 is vertically aligned with the first gear 4. The positioning side plate 27 is symmetrically fixedly installed inside the bottom of the cable branch box 3. The splash-proof cavity... The body 39 is fixedly installed on both sides of the top of the cable branch box 3. The teeth on the second gear 7 are distributed at an angle of 180°. The first sprocket 6 at the top of the transmission chain 8 is connected to the second gear 7. The first sprocket 6 at the bottom of the transmission chain 8 is connected to the spiral blade 10. Nylon brushes are fixedly installed at equal intervals on the sides of the first frame 16 and the second frame 19 near the filter screen 17. The bottom of the push plate 38 is symmetrically fixedly installed with key clips. The top of the guide base plate 37 has a slot. The L-shaped air cylinder 43 is hollow inside. A sealed cavity is formed between the second piston rod 44, the L-shaped air cylinder 43 and the first piston rod 40. Heat dissipation grooves are equidistantly opened on both sides of the inside of the cable branch box 3. The push plate 38 is horizontally aligned with the heat dissipation grooves.

[0036] The working principle is as follows: During use, the semiconductor condenser 14 can be operated. Through the semiconductor condenser 14, outside air can be delivered to the inside of the cable branch box 3. Simultaneously, the semiconductor condenser 14 can process the air, adsorbing and condensing the moisture in the air. At this time, the drain hole at the bottom of the semiconductor condenser 14 is interconnected with the guide cavity 11, allowing the condensed water to be discharged outwards through the guide cavity 11. Furthermore, the air entering the cable branch box 3 can cool the electronic components and circuits inside the cable branch box 3. Heat dissipation holes are provided on both sides of the inside of the cable branch box 3, allowing heat to be discharged outwards, thus completing the cooling and dehumidification work inside the cable branch box 3. Simultaneously, the worm gear 12 and the semiconductor... The fan blades inside the condenser 14 are connected so that, during operation, the semiconductor condenser 14 can drive the worm gear 12 to rotate. When the worm gear 12 rotates, it drives the worm wheel 9 to rotate. When the worm wheel 9 rotates, it drives the first sprocket 6 and the second gear 7 to rotate. When the first sprocket 6 at the top of the transmission chain 8 rotates, it drives the first sprocket 6 at the bottom of the transmission chain 8 to rotate, allowing the spiral blades 10 to rotate inside the guide cavity 11. This removes scale from the guide cavity 11, preventing the condensate from being trapped inside the semiconductor condenser 14. At the same time, when the first sprocket 6 at the top of the transmission chain 8 rotates, it drives the second gear 7 to rotate. When the second gear 7 rotates to mesh with the first gear 4... The first gear 4 can rotate, and when the first gear 4 rotates, it can drive the winding shaft 5 to rotate, so that the winding shaft 5 can pull the connecting rope 34 to drive the connecting plate 33 and the third rack 35 to move downward. At this time, when the third rack 35 moves downward, it can move along the surface of the fourth gear 28, and thus drive the fourth gear 28 to rotate. When the fourth gear 28 rotates, it can drive the third gear 25 to rotate, and the third gear 25 meshes with the fourth rack 36. Therefore, the third gear 25 can drive the fourth rack 36 to move closer to one end of the cable branch box 3, so that the push plate 38 can be inserted into the heat dissipation hole inside the cable branch box 3, which can push out the flocculent impurities accumulated inside the heat dissipation hole. And, through the sliding penetration of the second piston rod 44, The heat dissipation hole is connected to the end of the push plate 38 opposite to the fourth rack 36, so that when the push plate 38 is displaced, it can drive the second piston rod 44 to move inside the L-shaped air cylinder 43. When the second piston rod 44 moves inside the L-shaped air cylinder 43, it can drive the first piston rod 40 to move up and down synchronously inside the L-shaped air cylinder 43. Thus, the first piston rod 40 can drive the second rack 20 to move along the surface of the fifth gear 41, causing the fifth gear 41 to drive the first rack 15 to move in the opposite direction. The first frame 16 and the second frame 19 are connected to the first rack 15 and the second rack 20 respectively, and the first frame 16 and the second frame 19 are staggered vertically, so that when the first frame 16 rises, the second frame 19 can move downward.Nylon brushes are fixedly mounted at equal intervals on the opposite sides of the first frame 16 and the second frame 19. When the first frame 16 and the second frame 19 move up and down, the nylon brushes move along the inner and outer surfaces of the filter screen 17, removing impurities adhering to the filter screen 17 and improving the smoothness of airflow through the filter screen 17. When the toothed area of ​​the second gear 7 rotates past the first gear 4, the first gear 4 loses its meshing force. The elasticity of the return spring 32 causes the connecting plate 33 and the third rack 35 to move and reset, allowing the third rack 35 to move in the opposite direction along the surface of the fourth gear 28. This causes the third gear 25 to rotate in the opposite direction, thus allowing the third gear 25 to move the fourth rack 36 away from the cable branch box 3, pushing the plate 3... 8 can be pulled out from the heat dissipation holes inside the cable branch box 3, facilitating normal air exhaust. The push plate 38 slides along a slot at the top of the guide plate 37 via a key at its bottom, allowing it to move linearly and improving the alignment accuracy between the push plate 38 and the heat dissipation holes. When the push plate 38 resets, it drives the second piston rod 44 to move synchronously, which in turn moves the first piston rod 40 and the second rack 20 back to their original positions. This allows the first frame 16 and the second frame 19 to move up and down again, cleaning the filter screen 17 again. When the first frame 16 and the second frame 19 are in their normal state, the internal nylon brushes are misaligned, preventing blockage of the filter screen 17 and allowing air to pass through the filter screen 17 into the semiconductor condenser 14, completing the operation.
