A digitally integrated energy-saving cable branch box

Abstract

This invention relates to the field of cable branch boxes and discloses a digitally integrated energy-saving cable branch box. It effectively solves the problem that current cable branch boxes with numerous heat dissipation holes on the outer wall are prone to rainwater entering the box and damaging internal electrical components. The invention includes a movable box with a waterproof cover at the top. Inside the movable box is a cable branch box with heat dissipation holes evenly distributed on both sides. The invention utilizes a screw threaded connection between a screw rod and a screw barrel. When the screw rod rotates, it moves upward relative to the screw barrel, pushing a support block upward. This causes two rotating support rods to rotate upward, pushing a support plate and the cable branch box at the top of the support plate upward. This moves the cable branch box above the heat dissipation groove, preventing rainwater from entering the cable branch box through the heat dissipation holes and protecting the internal electrical components.

Description

Technical Field

[0001] This invention belongs to the field of cable branch boxes, specifically a digitally integrated energy-saving cable branch box. Background Technology

[0002] With the continuous development of cable-based power distribution networks, when small-capacity independent loads are concentrated, cable branch boxes can be used to connect multiple cable branches. Because branch boxes cannot directly operate on each branch, but only serve as cable branches, their main function is to split or transfer cables. Cable branch boxes are generally divided into power cable branch boxes, lighting cable branch boxes, and metering boxes. They are the final-level equipment in a power distribution system. Cable branch boxes are generally used outdoors and are typically enclosures. To dissipate heat from the internal electrical components, ventilation holes are provided on the outer wall of the enclosure. However, the following drawbacks still exist:

[0003] Because the enclosure is fixed in place and has many ventilation holes on its outer wall, rainwater can easily enter the cable branch box, which can damage the electrical components inside. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a digitally integrated energy-saving cable branch box, which effectively solves the problem that the current box has many heat dissipation holes on the outer wall, which makes it easy for rainwater to enter the inside of the cable branch box, thereby affecting the electrical components inside the cable branch box and causing damage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a digitally integrated energy-saving cable branch box, comprising a mobile box, a waterproof cover installed on the top of the mobile box, a cable branch box inside the mobile box, heat dissipation holes evenly opened on both sides of the cable branch box, heat dissipation grooves symmetrically opened on both sides of the mobile box, the heat dissipation grooves being adapted to the heat dissipation holes, a waterproof adjustment component provided below the cable branch box, a heat dissipation groove opening and closing component installed on the side of the heat dissipation groove away from the cable branch box, and a fire extinguishing component installed inside the waterproof cover;

[0006] The waterproof adjustment assembly includes a support plate located below the cable branch box. The bottom end of the support plate has symmetrical grooves. A slider is slidably connected inside the groove. The bottom end of the slider is rotatably connected to a rotating support rod. The bottom end of the rotating support rod is rotatably connected to the inner bottom wall of the movable box. The two rotating support rods are arranged in an X shape, and an adjustment unit is installed between the two rotating support rods.

[0007] Preferably, the adjustment unit includes a support block disposed between two rotating support rods. Rotating shafts are symmetrically installed at both ends of the support block and are rotatably connected to the rotating support rods. Screws are symmetrically provided at the bottom end of the support block, and a screw cylinder is provided on the outside of the screw. The screw cylinder is threadedly connected to the screw and is fixedly installed on the inner bottom wall of the movable box.

[0008] Preferably, the bottom end of the support block is symmetrically provided with a first rotating groove, and the top end of the screw is provided with a first rotating block, which is rotatably connected to the first rotating groove.

[0009] Preferably, a sprocket is installed on the outer side of the screw, and a chain is meshed between the outer sides of the two sprockets. A handle is installed on one side of the chain, and the sprocket is located between the support block and the screw barrel.

[0010] Preferably, the heat dissipation groove opening and closing assembly includes a second rotating groove symmetrically opened on the inner wall of the heat dissipation groove, an unwinding roller is provided inside the heat dissipation groove, a second rotating block is symmetrically installed at both ends of the unwinding roller, the second rotating block is rotatably connected to the second rotating groove, a gear is symmetrically installed on the outer side of the unwinding roller, a rack is meshed on the side of the gear near the inside of the moving box, and the rack is symmetrically installed on both sides of the support plate.

[0011] Preferably, a waterproof plate is provided on the side of each of the two heat dissipation slots that is far apart from each other. The top of the waterproof plate is rotatably connected to the outer wall of the mobile box. A pulling unit is installed on the top of the waterproof plate, and a traction rope is installed on the bottom of the waterproof plate. The other end of the traction rope is fixedly connected to the unwinding roller.

[0012] Preferably, the pulling unit includes a sleeve disposed above the waterproof membrane, a movable block slidably connected inside the sleeve, a connecting rod installed on the side of the movable block away from the moving box, a spring installed on the other side of the movable block, one end of the spring being fixedly connected to the inner wall of the sleeve, the sleeve being rotatably connected to the moving box, and the connecting rod being rotatably connected to the waterproof membrane.

[0013] Preferably, the fire extinguishing assembly includes a storage tank inside the waterproof cover, the storage tank extending to the inner top wall of the mobile box, a sliding groove inside the storage tank extending to the front of the mobile box, a baffle slidably connected inside the sliding groove, a handle installed on the front of the baffle, and the storage tank being filled with ammonium phosphate.

[0014] Preferably, a packing tube is installed at the top of the mobile box, the packing tube is connected to the inside of the storage tank, and a top sleeve is threaded to the top of the packing tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In this invention, the screw is threadedly connected to the screw barrel. After the screw rotates, the screw moves upward relative to the screw barrel, thereby pushing the support block to move upward. This causes both rotating support rods to rotate upward, pushing the support plate and the cable branch box at the top of the support plate to move upward, so that the cable branch box moves above the heat dissipation groove, thereby preventing rainwater from entering the inside of the cable branch box through the heat dissipation holes, thus protecting the electrical components inside the cable branch box.

[0017] (2) After the support plate moves upward, the unwinding roller is driven to rotate by the gear, which causes the traction rope to wrap around the outside of the unwinding roller, increasing the tension at the bottom of the waterproof plate, thereby pulling the waterproof plate downward and causing the waterproof plate to cover the heat dissipation groove, thereby reducing rainwater from entering the mobile box from the heat dissipation groove and improving the waterproof effect.

[0018] (3) The invention moves the screw back, which drives the support plate and cable branch box back. At this time, the unwinding roller rotates, which loosens the traction rope. At this time, the tension on the waterproof plate decreases, which causes the connecting rod to move back under the elastic force of the spring, and then drives the waterproof plate to rotate upward, thereby opening the heat dissipation groove for heat dissipation.

[0019] (4) When a fire occurs in the cable branch box, the baffle is pulled out from the sliding groove. The storage groove is filled with ammonium phosphate. After the baffle is pulled out, the ammonium phosphate falls onto the cable branch box, thereby extinguishing the fire, improving the fire extinguishing speed, and facilitating the protection of the cable branch box.

[0033] In Example 3, based on Example 1, the fire extinguishing component 8 includes a storage tank 801 inside the waterproof cover 2, the storage tank 801 extending to the inner top wall of the mobile box 1, a sliding groove 802 inside the storage tank 801 extending to the front of the mobile box 1, a baffle 803 slidably connected inside the sliding groove 802, a handle 804 installed on the front of the baffle 803, the storage tank 801 is filled with ammonium phosphate, a packing tube 805 is installed at the top of the mobile box 1, the packing tube 805 is connected to the inside of the storage tank 801, and a top sleeve 806 is threadedly connected to the top of the packing tube 805.

[0034] Working principle: When there is heavy rain, the cable branch box 4 needs to be waterproofed. The staff pulls the chain 6058 with the handle 6059. The chain 6058 meshes with two sprockets 6057. After the chain 6058 moves, it drives the two sprockets 6057 to rotate. The screw 6055 at the bottom of the sprocket 6057 is threadedly connected to the screw barrel 6056. After the screw 6055 rotates, it moves upward relative to the screw barrel 6056, thereby pushing the support block 6051 to move upward. This causes the two rotating support rods 604 to rotate upward, thereby pushing the support plate 601 and the cable branch box 4 at the top of the support plate 601 to move upward. This moves the cable branch box 4 above the heat dissipation groove 3, thus preventing rainwater from entering the inside of the cable branch box 4 through the heat dissipation hole 5, thereby protecting the electrical components inside the cable branch box 4.

[0035] When the support plate 601 moves upward, the rack 701 on the support plate 601 meshes with the gear 705. As the support plate 601 moves upward, the gear 705 drives the unwinding roller 703 to rotate, which in turn causes the traction rope 706 to wrap around the outside of the unwinding roller 703. This pulls the waterproof plate 707 to rotate downward, so that the waterproof plate 707 covers the heat dissipation groove 3, thereby reducing rainwater from entering the interior of the mobile box 1 from the heat dissipation groove 3 and improving the waterproof effect.

[0036] When the rain stops, the chain 6058 is pushed in the opposite direction to move, which in turn drives the screw 6055 to move back, thereby driving the support plate 601 and the cable branch box 4 to move back. At this time, the unwinding roller 703 rotates, causing the traction rope 706 to loosen. The downward pulling force on the waterproof plate 707 is reduced, which causes the connecting rod 7083 to move back under the elastic force of the spring 7084, thereby driving the waterproof plate 707 to rotate upward, thereby opening the heat dissipation groove 3 to facilitate heat dissipation.

[0037] When a fire occurs in cable branch box 4, the baffle 803 is pulled out from the sliding groove 802. The storage tank 801 is filled with ammonium phosphate. After the baffle 803 is pulled out, the ammonium phosphate falls onto the cable branch box 4, thus extinguishing the fire. After use, the baffle 803 is pushed back, the top sleeve 806 is unscrewed, and ammonium phosphate is refilled into the storage tank 801 through the filling tube 805.
