Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box with an insulation function. Background Art

[0002] The distribution box is a device responsible for completing power control, protection, conversion and distribution at the end of the urban rail transit power supply system. It is mainly composed of wires, components (including disconnectors, circuit breakers, etc.) and boxes. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. Due to the complex structure of the traction power supply control system, it has high requirements for temperature, humidity, and corrosion resistance. A high-stability and high-reliability distribution box with a reasonable structure is required. Once the electrical components in the distribution box leak, it will be dangerous. In order to prevent electrical components from leaking, the existing device will use an insulating structure to block the current in the distribution box. In order to ensure insulation without dead ends, a fully enclosed distribution box will be used. However, this insulation and leakage prevention method cannot dissipate the heat generated by the electrical components under normal use, which is more likely to cause overheating, short circuit or leakage of the electrical components. Once leakage occurs, the charge in the distribution box cannot be released, which will cause the components to burn or explode.

[0003] Patent No. CN201821428667.1 discloses an insulated distribution box. The electrical components of the patent are installed on the mounting plate. Since the mounting plate is made of wood, there is no need to worry about cross-current between the lines. The electrical lines between the electrical components are installed in the line protection cover. The main channel and branch channel arranged on the line protection cover make the electrical lines more organized and uncluttered. After the electrical components are installed, the upper cover of the distribution box is covered on the distribution box body, and the screws are tightened after the fasteners are fixed. When maintenance is required, the hand handle is opened to open the distribution box door, and the internal lines can be maintained. The structure is simple and convenient. The structure is simple, convenient and practical, the internal connection lines can be organized in an orderly manner, and the insulation is strong, so it will not cause electric shock injuries to the human body, and it has good waterproof performance. Although this patent solves the above problems, it still adopts a fully enclosed insulation method, and it is impossible to insulate according to the leakage situation of the electrical components, which makes it difficult for the heat of the electrical components to dissipate out of the distribution box when they are in use, and it is more likely to cause the electrical components to overheat and short-circuit, resulting in leakage. Therefore, it is very necessary to design a distribution box with insulation function that can take insulation measures according to the leakage situation of the electrical components themselves without affecting the normal heat dissipation of the distribution box. Summary of the invention

[0004] The purpose of the present invention is to provide a distribution box with insulation function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a distribution box with insulation function, comprising a box body, the outer surface of the box body is fixedly connected with a driving device, the inner surface of the driving device is transmission-connected with a bidirectional lead screw, the outer surface of the bidirectional lead screw is movably connected with a push block, the rear side surface of the inner wall of the box body is fixedly connected with a sensor, the two sides of the inner wall of the box body are fixedly connected with slide rails, the inner surface of the slide rails is slidably connected with an insulating plate 1 and an insulating plate 2, the bottom surfaces of the insulating plate 1 and the insulating plate 2 are fixedly connected with a protrusion, the rear side surface of the insulating plate 1 is fixedly connected with a card, the inner surface of the insulating plate 2 is slidably connected with a sliding shaft, the bottom of the box body is provided with a drying device for absorbing moisture to prevent moisture from conducting after leakage and causing current to spread in the box body, the rear side of the box body is provided with a conductive device for quickly conducting current to the ground for dissipation after leakage of electrical components, and the bidirectional lead screw is transmission-connected with a push block, the inner surface of the bidirectional lead screw is movably connected ... The two-way screw rod rotates and passes through the rear side of the box body, and the two-way screw rod is rotatably connected to the front side of the inner wall of the box body. Heat dissipation grooves are provided on both sides of the box body, a spring is arranged between the sliding shaft and the second insulating plate, and a through hole is provided on the inner side of the card plate. When the sensor senses that the electrical component in the box body is leaking, it sends an electrical signal to the driving device. After receiving the signal, the driving device starts and drives the two-way screw rod to rotate. When the two-way screw rod rotates, it drives the two push blocks to approach each other, and the two push blocks push the two protrusions to get closer. The two protrusions then drive the insulating plate 1 and the insulating plate 2 to merge. When the insulating plate 1 and the insulating plate 2 are merged, the card plate on the insulating plate 1 is inserted into the inside of the insulating plate 2, and the card plate pushes the sliding shaft to slide downward. When the through hole on the card plate is aligned with the sliding shaft, the spring under the sliding shaft makes the sliding shaft bounce up and insert into the through hole to limit the card plate, separate the insulating plate 1 and the insulating plate 2, so that the heat generated when the electrical component works again can be dissipated from the heat dissipation groove.

[0006] According to the above technical solution, the drying device includes a limit frame, a drying box, and a screen plate. The limit frame is fixedly connected to the bottom of the box body, the drying box is arranged inside the limit frame, and the screen plate is hinged to the side of the drying box. The drying device also includes a connecting rod, a clamping claw, a push plate, and a limit convex plate. The connecting rod is fixedly connected to the inner surface of the push block, the clamping claw is fixedly connected to the bottom end of the connecting rod, the push plate is clamped on the inner surface of the clamping claw, and the limit convex plate is fixedly connected to the inner wall of the drying box. A slide groove is provided on the top of the drying box, and the connecting rod is slidably connected to the inner surface of the slide groove, the push plate is slidably connected to the inner surface of the drying box, and the push plate is slidably connected to the outer surface of the limit convex plate. The screen plate is opened to put the solid desiccant into the drying box, and then Insert the drying box into the limit frame. When the distribution box is running, the solid desiccant in the drying box can absorb moisture in the air inside the box. When the reciprocating screw rotates, it drives the push block to move back and forth, and the push block drives the connecting rod to move back and forth. The connecting rod then drives the push plate to slide back and forth inside the drying box and on the surface of the limit convex plate through the clamping claw. The push plate slides on the limit convex plate to reduce the friction during sliding, and will not be affected by the friction to deflect and overturn. When the push plate slides back and forth, it pushes the solid desiccant inside the drying box to turn over. When the desiccant reaches a certain usage time, the screws at the connection between the push block and the connecting rod can be unscrewed, and then the connecting rod and the push plate can be separated, so that the drying box can be taken out of the box again, which is convenient for replacing the solid desiccant inside it.

[0007] According to the above technical solution, the conductive device includes a mounting frame, a conductive sheet, and a conductive metal wire. The mounting frame is fixedly connected to the rear side of the inner wall of the box body, the conductive sheet is fixedly connected to both sides of the mounting frame, and the conductive metal wire is fixedly connected to the rear side of the connecting rod. The conductive device also includes an insulating sleeve, an insulating box, a conductive plate, a grounding nail, and an insulating foot pad. The insulating sleeve is fixedly connected to the inner surface of the rear side of the box body, the insulating box is fixedly connected to the rear side of the box body, the conductive plate is fixedly connected to the bottom of the insulating box, the grounding nail is fixedly connected to the bottom surface of the conductive plate, and the insulating foot pad is fixedly connected to the bottom surface of the box body. The conductive metal wire is slidably connected to the inner surface of the conductive sheet, the conductive metal wire is slidably connected to the inner surface of the insulating sleeve, and the grounding nail is fixedly connected to the bottom surface of the conductive plate. The nails penetrate the bottom of the insulating box. When the electrical component leaks electricity, the current will first flow to the mounting frame, and then be introduced into the conductive sheet through the mounting frame. At this time, the connecting rod moves back and forth and drives the metal conductive wire to slide in the conductive sheet. Friction is generated when the metal conductive wire slides with the conductive sheet, so that the metal conductive wire can quickly absorb the current, and then the current is conducted out of the box through the metal conductive wire. In the process of the conductive metal wire conducting the current out of the box, the insulating sleeve can prevent the current from directly contacting the box and preventing the current from being absorbed by the box. At the same time, the insulating box can prevent the conductive metal wire from contacting foreign objects. After the conductive metal wire conducts the current to the conductive plate, the conductive plate then conducts the current into the ground through the grounding nail for dissipation, and the insulating foot pad can block the current contact between the box and the ground.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0009] The present invention is provided with an insulating plate 1, an insulating plate 2, a convex block, a push block, a card plate, and a sliding shaft. The insulating plate 1 and the insulating plate 2 are combined to block the heat dissipation slot, so that the box body is sealed, and dust in the box body is prevented from absorbing electric charges and then drifting outside the box body. The dust absorbing electric charges is easy to generate static electricity after accumulation, which will cause safety hazards if there are inflammable and explosive items around. The sliding shaft is popped up and inserted into the through hole to limit the card plate, so that the insulating plate 1 and the insulating plate 2 are more firmly attached, the sealing is improved, and then the anti-leakage effect is improved;

[0010] The present invention is provided with a connecting rod, a clamping claw, a push plate, and a limiting convex plate, so that the solid desiccant in the drying box can absorb moisture in the air in the box. After the moisture is reduced, it can prevent the current generated by the leakage of the electrical components from being quickly conducted to the box through the moisture, thereby reducing the risk of leakage. When the push plate slides back and forth, it pushes the solid desiccant in the drying box to flip, thereby improving the contact efficiency between the micropores on the surface of the fixed desiccant and the air, thereby improving the moisture adsorption efficiency of the fixed desiccant.

[0011] The present invention is provided with an insulating sleeve, an insulating box, a conductive plate, a grounding nail and an insulating foot pad. The metal conductive wire can quickly absorb the current, and then the current is led out of the box body through the metal conductive wire, so as to prevent the electrical components from burning or exploding due to the charge overload in the box body when the electrical components are not repaired in time and continue to leak. The insulating sleeve can prevent the current from directly contacting the box body and preventing the current from being absorbed by the box body. The insulating box can prevent the conductive metal wire from contacting foreign objects. The grounding nail can lead the current into the ground for dissipation. The insulating foot pad can block the current contact between the box body and the ground, so as to make the conductive process safer and improve the protection effect.

The bottom of the box body 1 is provided with a drying device 7 for absorbing moisture to prevent moisture from conducting after leakage and causing current to spread in the box body 1. The rear side of the box body 1 is provided with a conductive device 8 for quickly conducting current to the ground and dissipating it after leakage of electrical components. The two-way screw rod 3 rotates and penetrates the rear side of the box body 1. The two-way screw rod 3 is rotatably connected to the front side of the inner wall of the box body 1. Heat dissipation grooves are provided on both sides of the box body 1. A spring is provided between the sliding shaft 65 and the insulating plate 2 61. A through hole is provided on the inner side of the card plate 64. The sliding shaft 65 pops up and is inserted into the through hole to limit the card plate 64, so that the insulating plate 1 6 and the insulating plate 2 61 fit more firmly, thereby improving the sealing and thus improving the anti-leakage effect.

[0025] Working principle: When the sensor 4 senses that the electrical components in the box body 1 are leaking, it sends an electrical signal to the driving device 2. After receiving the signal, the driving device 2 starts and drives the bidirectional screw 3 to rotate. When the bidirectional screw 3 rotates, it drives the two push blocks 63 to move closer to each other. The two push blocks 63 push the two protrusions 62 to move closer. The two protrusions 62 then drive the insulating plate 1 6 and the insulating plate 2 61 to merge, blocking the heat dissipation slot, making the box body 1 sealed, and preventing the dust in the box body 1 from absorbing the charge and then drifting to the outside of the box body 1. The dust that absorbs the charge is easy to generate static electricity after accumulation, which will have safety hazards if there are flammable and explosive items around. When the insulating plate 1 6 and the insulating plate 2 61 are combined, the card plate 64 on the insulating plate 1 6 is inserted into the inside of the insulating plate 2 61, and the card plate 64 pushes the sliding shaft 65 to slide downward. When the through hole on the card plate 64 is aligned with the sliding shaft 65, the spring under the sliding shaft 65 makes the sliding shaft 65 bounce up and insert into the through hole to limit the card plate 64, so that the insulating plate 1 6 and the insulating plate 2 61 fit more firmly, improve the sealing, and then improve the anti-leakage effect. When the leakage problem of the electrical component is solved, the insulating plate 1 6 and the insulating plate 2 61 are separated, so that the heat generated when the electrical component works again can be dissipated from the heat sink.

[0026] See also Figure 1-8On the basis of the above embodiment, another embodiment of the present invention includes a drying device 7, which includes a limiting frame 71, a drying box 72, and a mesh plate 73. The limiting frame 71 is fixedly connected to the bottom of the box body 1, and the drying box 72 is arranged inside the limiting frame 71. The mesh plate 73 is hinged on the side of the drying box 72. The solid desiccant in the drying box 72 can absorb moisture in the air in the box body 1. After the moisture is reduced, it can prevent the current generated by the leakage of the electrical components from being quickly conducted to the box body 1 through the moisture, thereby reducing the risk of leakage. The drying device 7 also includes a connecting rod 74, a clamping claw 75, a push plate 76, a limiting convex Plate 77, connecting rod 74 is fixedly connected to the inner surface of push block 63, clamping claw 75 is fixedly connected to the bottom end of connecting rod 74, push plate 76 is clamped on the inner surface of clamping claw 75, and limiting convex plate 77 is fixedly connected to the inner wall of drying box 72.

When push plate 76 slides back and forth, it pushes the solid desiccant inside the drying box 72 to flip, thereby improving the contact efficiency between the micropores on the surface of the fixed desiccant and the air, thereby improving the efficiency of the fixed desiccant in absorbing moisture.

[0027] Working principle: open the mesh plate 73 and put the solid desiccant into the drying box 72, and then insert the drying box 72 into the limit frame 71. When the distribution box is running, the solid desiccant in the drying box 72 can absorb the moisture in the air in the box body 1. After the moisture is reduced, it can prevent the current generated by the leakage of electrical components from being quickly transmitted to the box body 1 through the moisture, thereby reducing the risk of leakage. When the reciprocating screw rotates, it drives the push block 63 to move back and forth, and the push block 63 drives the connecting rod 74 to move back and forth. The connecting rod 74 then drives the push plate 76 to slide back and forth inside the drying box 72 and on the surface of the limit convex plate 77 through the clamping claw 75. When the push plate 76 slides back and forth, it pushes the solid desiccant inside the drying box 72 to turn over, thereby improving the contact efficiency between the micropores on the surface of the fixed desiccant and the air, thereby improving the efficiency of the fixed desiccant in absorbing moisture. When the desiccant has been used for a certain period of time, the screws at the connection between the push block 63 and the connecting rod 74 can be unscrewed, and then the connecting rod 74 can be separated from the push plate 76, so that the drying box 72 can be taken out of the box body 1 again, so as to facilitate the replacement of the solid desiccant inside it.

[0028] See also Figure 1-8On the basis of the above embodiment, another embodiment of the present invention includes a conductive device 8, the conductive device 8 includes a mounting frame 81, a conductive sheet 82, and a conductive metal wire 83. The mounting frame 81 is fixedly connected to the rear side of the inner wall of the box body 1, the conductive sheet 82 is fixedly connected to both sides of the mounting frame 81, and the conductive metal wire 83 is fixedly connected to the rear side of the connecting rod 74. The metal conductive wire can quickly absorb the current, and then the current is led out of the box body 1 through the metal conductive wire to prevent the electrical components from being burned or exploded due to the overload of the charge in the box body 1 when the electrical components are not repaired in time and continue to leak electricity. The conductive device 8 also includes an insulating sleeve 84, an insulating box 85, a conductive plate 86, a grounding nail 87, and an insulating foot pad 88. The insulating sleeve 84 is fixedly connected On the inner surface of the rear side of the box body 1, the insulating box 85 is fixedly connected to the rear side surface of the box body 1, the conductive plate 86 is fixedly connected to the bottom of the insulating box 85, the grounding nail 87 is fixedly connected to the bottom surface of the conductive plate 86, and the insulating foot pad 88 is fixedly connected to the bottom surface of the box body 1.

The insulating foot pad 88 can block the current contact between the box body 1 and the ground, making the conductive process safer and improving the protection effect.

[0029] Working principle: When an electrical component leaks electricity, the current will first flow to the mounting frame 81, and then be introduced into the conductive sheet 82 through the mounting frame 81. At this time, the connecting rod 74 moves back and forth and drives the metal conductive wire to slide in the conductive sheet 82. When the metal conductive wire slides with the conductive sheet 82, friction is generated, so that the metal conductive wire can quickly absorb the current, and then the current is led out of the box body 1 through the metal conductive wire to prevent the electrical component from being burned or exploded due to the overload of the charge in the box body 1 when the electrical component is not repaired in time and continues to leak electricity. In the process of the conductive metal wire leading the current out of the box body 1, the insulating sleeve 84 can prevent the current from directly contacting the box body 1 and preventing the current from being absorbed by the box body 1. At the same time, the insulating box 85 can prevent the conductive metal wire 83 from contacting foreign objects.
