Description

Technical Field

[0001] The utility model belongs to the technical field of low-voltage distribution boxes, and particularly relates to an automatic low-voltage distribution box. Background Technique

[0002] An automatic low-voltage distribution box is a power distribution device integrated with an automatic control system, mainly used for power distribution and control in industrial and civil applications.

[0003] Most of the existing automatic low-voltage distribution boxes are installed outdoors, and the heat dissipation openings are usually opened on the side of the distribution cabinet. When encountering rainy or snowy days, etc., rainwater easily enters the interior of the distribution box through the heat dissipation openings, and after the rainwater enters the distribution box, it easily splashes onto the internal electrical components, thereby causing the electrical components to have poor contact or damage, resulting in certain economic losses. Therefore, we propose an automatic low-voltage distribution box. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic low-voltage distribution box. By setting a protection component, specifically, when the protective cover is pressed downwards, the convex block on the protective cover leaves the elastic clamping block, then the protective cover rotates downwards on the fixed shaft to block the heat dissipation opening, thereby preventing rain and snow from entering the interior of the distribution box through the heat dissipation opening. Since the bottom of the protective cover is open after it rotates downwards, the heat inside the distribution box can be discharged smoothly, and it can play a protective role without affecting the heat dissipation of the distribution box, solving the problem that rainwater easily enters the interior of the distribution box through the heat dissipation opening, and after the rainwater enters the distribution box, it easily splashes onto the internal electrical components, thereby causing the electrical components to have poor contact or damage, resulting in certain economic losses.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an automatic low-voltage distribution box, including a distribution box, a shielding component is arranged above the distribution box, both the left side and the right side of the distribution box are fixedly connected with protection components, the two protection components are symmetrically arranged with the distribution box as the center, and the parts included in the two protection components are the same. The protection component includes a protective cover, and fixed blocks are arranged on both the front and the back of the protective cover;

[0007] Both the left and right sides of the distribution box are provided with heat dissipation openings. A shielding leaf is arranged below the protective cover. One side of the two corresponding fixing blocks is fixedly connected with a fixing shaft. A convex block is fixedly connected to the top of the protective cover. An elastic clamping block is arranged above the protective cover. By setting the protection component, specifically, when the protective cover is pressed downward, the convex block on the protective cover leaves the elastic clamping block, and then the protective cover rotates downward on the fixing shaft to block the heat dissipation opening, thereby preventing rain and snow from entering the interior of the distribution box through the heat dissipation opening. Since the bottom of the protective cover is open after it rotates downward, the heat inside the distribution box can be smoothly discharged, and it can play a protective role without affecting the heat dissipation of the distribution box.

[0008] Furthermore, one side of the shielding leaf close to the distribution box is fixedly connected to the surface of the distribution box. The fixing shaft penetrates through the protective cover and extends to the outside. The outer surface of the fixing shaft is rotatably connected to the protective cover. One side of the elastic clamping block close to the distribution box is fixedly connected to the surface of the distribution box. The top of the convex block contacts the bottom of the elastic clamping block. Pull the protective cover upward to move the convex block to the elastic clamping block. When the elastic clamping block is pushed, the convex block smoothly moves into the elastic clamping block. Subsequently, the elastic clamping block resets under the action of its own elasticity and supports the protective cover through cooperation with the convex block.

[0009] Furthermore, the shielding component includes a shed. A fixing seat is fixedly connected to the top of the distribution box. The interior of the fixing seat is a cavity. A support block is fixedly connected to the bottom of the inner wall of the fixing seat. A motor is fixedly connected to the right side of the support block. The left output end of the motor is fixedly connected with an elliptical roller. By setting the shielding component, specifically, the shed can play a role in blocking rain and snow, can reduce the rainwater remaining on the top of the distribution box, reduce corrosion, and improve the service life of the distribution box housing. Start the motor to drive the elliptical roller to rotate, and the connecting plate will drive the shed to move up and down reciprocally through the lifting rod, thereby shaking off the attached snow and avoiding the problem that excessive attachment of snow increases the weight and affects the distribution box.

[0010] Furthermore, two heating seats are fixedly connected to the bottom of the shed. The two heating seats are symmetrically arranged. The parts connected to the two heating seats are the same. Two vertical rods are fixedly connected to the bottom of the heating seat. Springs are sleeved on the outer sides of the two vertical rods. Limiting frames are slidably connected to the outer surfaces of the two vertical rods. A heating wire is arranged inside the heating seat. By heating the heating wire, the shed is in a state of relatively high temperature, which can reduce the snow remaining on the shed.

[0011] Further, two lifting rods are fixedly connected to the center of the bottom of the shed. The bottoms of the two lifting rods penetrate through the fixed seat and extend into the interior. A connecting plate is fixedly connected to the bottoms of the two lifting rods. When the elliptical roller rotates, the protruding position will push the connecting plate upward, and the lifting rods will drive the shed to move together. When the elliptical roller rotates to a lower position, the connecting plate will drive the shed to reset downward through the lifting rods.

[0012] Further, the bottom of the limiting frame is fixedly connected to the top of the distribution box. The top of the spring is fixedly connected to the bottom of the heating seat. The bottom of the spring is fixedly connected to the top of the limiting frame. The bottom of the connecting plate is in contact with the outer surface of the elliptical roller. The bottom of the spring penetrates through the limiting frame and extends to the outside. A limiting block is fixedly connected to the bottom of the spring. When the shed moves upward, it will drive the vertical rod to slide in the limiting frame and stretch the spring. It can assist the shed to reset downward under the elastic action of the spring, and the vertical rod slides on the limiting frame, which can improve the stability.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting the protection component in the utility model, specifically, when the protective cover is pressed downward, the convex block on the protective cover leaves the elastic clamping block, and then the protective cover flips downward on the fixed shaft to block the heat dissipation port, thus preventing rain and snow from entering the interior of the distribution box through the heat dissipation port. Since the bottom of the protective cover is open after it flips downward, the heat inside the distribution box can be smoothly discharged, which can provide protection without affecting the heat dissipation of the distribution box.

[0015] 2. By setting the shielding component in the utility model, specifically, the shed can play a role in blocking rain and snow, reducing the rainwater remaining on the top of the distribution box, reducing corrosion, and improving the service life of the distribution box housing. Starting the motor to drive the elliptical roller to rotate, the connecting plate will drive the shed to move up and down reciprocally through the lifting rods, thereby shaking off the attached snow and avoiding the problem that too much attached snow increases the weight and affects the distribution box.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figures 1-5As shown in the figure, the utility model relates to an automatic low-voltage distribution box, which includes a distribution box 1. A shielding component 11 is arranged above the distribution box 1. Protective components 12 are fixedly connected to both the left and right sides of the distribution box 1. The two protective components 12 are symmetrically arranged with the distribution box 1 as the center. The parts included in the two protective components 12 are the same. The protective component 12 includes a protective cover 121. Fixed blocks 122 are arranged on both the front and back of the protective cover 121. Heat dissipation openings 13 are opened on both the left and right sides of the distribution box 1. A shielding leaf 123 is arranged below the protective cover 121. Fixed shafts 124 are fixedly connected to the opposite sides of the two fixed blocks 122. A convex block 125 is fixedly connected to the top of the protective cover 121. An elastic clamping block 126 is arranged above the protective cover 121. By setting the protective component 12, specifically, when the protective cover 121 is pressed downwards, the convex block 125 on the protective cover 121 leaves the elastic clamping block 126, and then the protective cover 121 rotates downwards on the fixed shaft 124 to block the heat dissipation opening 13, thereby preventing rain and snow from entering the interior of the distribution box 1 through the heat dissipation opening 13. Since the bottom of the protective cover 121 is open after it rotates downwards, the heat inside the distribution box 1 can be discharged smoothly. It can play a protective role without affecting the heat dissipation of the distribution box 1. One side of the shielding leaf 123 close to the distribution box 1 is fixedly connected to the surface of the distribution box 1. The fixed shaft 124 penetrates through the protective cover 121 and extends to the outside. The outer surface of the fixed shaft 124 is rotationally connected to the protective cover 121. One side of the elastic clamping block 126 close to the distribution box 1 is fixedly connected to the surface of the distribution box 1. The top of the convex block 125 contacts the bottom of the elastic clamping block 126. When the protective cover 121 is pulled upwards, the convex block 125 moves to the elastic clamping block 126, and the elastic clamping block 126 is pushed to enable the convex block 125 to move smoothly into the elastic clamping block 126. Subsequently, the elastic clamping block 126 resets under the action of its own elasticity. By cooperating with the convex block 125, the protective cover 121 will be supported. The shielding component 11 includes a shed 111. A fixed seat 112 is fixedly connected to the top of the distribution box 1. The interior of the fixed seat 112 is a cavity. A support block 21 is fixedly connected to the bottom of the inner wall of the fixed seat 112. A motor 22 is fixedly connected to the right side of the support block 21. An elliptical roller 23 is fixedly connected to the left output end of the motor 22. By setting the shielding component 11, specifically, the shed 111 can play a role in shielding rain and snow, can reduce the rainwater remaining on the top of the distribution box 1, reduce corrosion, and improve the service life of the housing of the distribution box 1. When the motor 22 is started to drive the elliptical roller 23 to rotate, the connecting plate 115 will drive the shed 111 to move up and down reciprocally through the lifting rod 114, thereby shaking off the attached snow and avoiding the problem that excessive attached snow increases the weight and affects the distribution box 1. Two heating seats 113 are fixedly connected to the bottom of the shed 111. The two heating seats 113 are symmetrically arranged. The parts connected to the two heating seats 113 are the same. Two vertical rods 31 are fixedly connected to the bottom of the heating seat 113. Springs 32 are sleeved on the outer sides of the two vertical rods 31. Limiting frames 33 are slidably connected to the outer surfaces of the two vertical rods 31.A heating wire 34 is provided inside the heating seat 113. By heating the heating wire 34, the shed 111 is in a state of relatively high temperature, which can reduce the snow remaining on the shed 111. Two lifting rods 114 are fixedly connected to the center of the bottom of the shed 111. The bottoms of the two lifting rods 114 penetrate through the fixed seat 112 and extend into the interior. A connecting plate 115 is fixedly connected to the bottoms of the two lifting rods 114. When the elliptical roller 23 rotates, the protruding position will push the connecting plate 115 upward, and the lifting rod 114 will drive the shed 111 to move together. When the elliptical roller 23 rotates to the lower position, it will cause the connecting plate 115 to drive the shed 111 to reset downward through the lifting rod 114. The bottom of the limiting frame 33 is fixedly connected to the top of the distribution box 1. The top of the spring 32 is fixedly connected to the bottom of the heating seat 113. The bottom of the spring 32 is fixedly connected to the top of the limiting frame 33. The bottom of the connecting plate 115 is in contact with the outer surface of the elliptical roller 23. The bottom of the spring 32 penetrates through the limiting frame 33 and extends to the outside. A limiting block is fixedly connected to the bottom of the spring 32. When the shed 111 moves upward, it will drive the vertical rod 31 to slide in the limiting frame 33 and stretch the spring 32. The elastic action of the spring 32 can assist the shed 111 to reset downward, and the vertical rod 31 sliding on the limiting frame 33 can improve the stability.

[0027] A specific application of this embodiment is:

[0028] In use, when encountering rainy or snowy weather, press the protective cover 121 downward. Then, the bump 125 on the protective cover 121 will push the elastic latch 126, so that it can smoothly separate from the elastic latch 126, releasing the fixation of the protective cover 121. Then, the protective cover 121 rotates on the fixed shaft 124 and flips downward to block the heat dissipation opening 13, thus preventing rain and snow from entering the distribution box 1 through the heat dissipation opening 13. The shielding blade 123 can play a shielding role again, improving the protection effect. Since the bottom of the protective cover 121 is open after it flips downward, the heat inside the distribution box 1 can be smoothly discharged. It can provide protection without affecting the heat dissipation of the distribution box 1. The awning 111 can play the role of blocking rain and snow, reducing the rainwater remaining on the top of the distribution box 1, reducing corrosion, and increasing the service life of the housing of the distribution box 1. By heating the heating wire 34, the awning 111 is in a state of relatively high temperature, which can reduce the snow remaining on the awning 111. When there is a lot of snow remaining on the awning 111, start the motor 22 to drive the elliptical roller 23 to rotate. Then, the elliptical roller 23 will push the connecting plate 115 upward, and the lifting rod 114 will drive the awning 111 to move together. At the same time, the vertical rod 31 will slide in the limit frame 33 and stretch the spring 32. Subsequently, under the elastic action of the spring 32, it will reset downward, and the awning 111 will reset downward. The lifting rod 114 drives the connecting plate 115 to move downward together, and the elliptical roller 23 will push the connecting plate 115 upward again. Repeating like this can make the awning 111 continuously move up and down, thus shaking off the attached snow and avoiding the problem that excessive attached snow increases the weight and affects the distribution box 1. When it is not rainy or snowy weather, pull the protective cover 121 upward, move the bump 125 to the elastic latch 126, and when the elastic latch 126 is pushed, the bump 125 smoothly moves into the elastic latch 126. Subsequently, the elastic latch 126 resets under its own elastic action and supports the protective cover 121 in cooperation with the bump 125, so that the heat dissipation opening 13 is more exposed, improving the heat dissipation effect.
