Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, and specifically to a heat-insulating and noise-reducing low-voltage distribution box. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, stable and reliable operation, and high space utilization. If the distribution box is used in a high temperature environment (such as sunlight, etc.) for a long time, the working environment temperature of the components inside the box will increase. When the temperature is too high, it will affect the operation of the components and even cause damage. In addition, the components will also generate certain noise when working. For this reason, the distribution box in the prior art needs to be insulated and noise reduced. In response to the emergence of the above problems, the prior art has not solved them well, which has brought troubles to the normal operation of work in this field. Therefore, there is an urgent need for a low-voltage distribution box with heat insulation and noise reduction to solve the above problems. Utility Model Content

[0003] The utility model provides a heat-insulating and noise-reducing low-voltage distribution box, which solves the problem in the related art that the operation of components will be affected by the excessively high application environment temperature of the distribution box.

[0004] The technical solution of the utility model is as follows: an insulated and noise-reducing low-voltage distribution box, comprising a box body, a transmission roller, a transmission belt, an insulating cotton layer and a fan, the box body comprising a plurality of side panels connected end to end, the side panels having a plurality of ventilation holes, the transmission roller being rotatably disposed in the box body, the transmission roller being two, respectively located on both sides of the side panels, the transmission belt being sleeved on the two transmission rollers, the insulating cotton layer being detachably disposed on the transmission belt, the insulating cotton layer being attached to the side panels to seal the ventilation holes, and the fan being rotatably disposed in the box body.

[0005] Optionally, it also includes a motor, bevel gear 1 and bevel gear 2, the motor is arranged in the housing, the bevel gear 1 and the bevel gear 2 are both rotatably arranged in the housing, the bevel gear 1 is coaxially arranged with the transmission roller, the bevel gear 2 is connected to the fan drive, the bevel gear 1 is meshed with the bevel gear 2, and the bevel gear 1 is connected to the motor drive.

[0006] Optionally, a brush is further included, and the brush is arranged in the box body. After the transmission roller rotates, the heat insulating cotton layer passes through the brush to clean the heat insulating cotton layer.

[0007] Optionally, it also includes a clamping plate 1 and a clamping plate 2, wherein the clamping plate 1 is arranged on the transmission belt and has a slot, and the clamping plate 2 is swingably arranged on the clamping plate 1 and has a clamping block, and after the clamping plate 2 swings, the clamping block is engaged with or unengaged with the slot to fix the thermal insulation cotton layer.

[0008] Optionally, a temperature probe is further included, which is arranged in the box and is used to monitor the temperature in the box.

[0009] Optionally, a mounting frame is also included, and the mounting frame is arranged on the top of the box.

[0011] Optionally, it also includes a foot and a screw, wherein the screw is threadedly connected to the bottom of the box body, and the foot is arranged on the screw.

[0012] The working principle and beneficial effects of the utility model are:

[0013] There are multiple ventilation holes on the side panel. Under normal conditions, the heat insulation cotton layer is attached to the side panel to block the ventilation holes. The heat insulation cotton layer is made of heat insulation material. While blocking, it also has the function of reducing noise, thereby isolating and blocking the sunlight, but it cannot block it 100%. For this reason, when the temperature in the box reaches the preset value, the driving member installed in the box drives the transmission roller to rotate. The transmission roller can drive the heat insulation cotton layer to move, pull the heat insulation cotton layer apart, gradually separate from the side panel, and no longer block the ventilation holes. In the process, the fan is driven to rotate, and the fans on the two side panels on the opposite sides cooperate to generate convection in the box. The gas passes through the ventilation holes on the side panels, thereby accelerating the gas flow in the box, taking away the heat on the components inside the box, and thus reducing the temperature in the box. It should be emphasized that in the process of the heat insulation cotton layer separating from the side panel, multiple ventilation holes are gradually opened, and the heat insulation cotton layer will always block a part of the ventilation holes. Through the movement of the heat insulation cotton layer, all ventilation holes can be connected to the outside world one after another. Then, as the transmission roller rotates, the transmission belt rotates with the heat-insulating cotton layer for several cycles, and then returns to the receiving gap, restoring the closed state, continuing to maintain the temperature inside the box and blocking the external high temperature.

[0028] Reference Figure 1 to Figure 8 , which is the first embodiment of the utility model, proposes a heat-insulating and noise-reducing low-voltage distribution box, including a box body 1, a transmission roller 2, a transmission belt 3, a heat-insulating cotton layer 4 and a fan 5. The box body 1 includes a plurality of side panels 6 connected end to end, and the side panels 6 have a plurality of ventilation holes 8. The transmission roller 2 is rotatably arranged in the box body 1. There are two transmission rollers 2, which are respectively located on both sides of the side panels 6. The transmission belt 3 is sleeved on the two transmission rollers 2. The heat-insulating cotton layer 4 is detachably arranged on the transmission belt 3. The heat-insulating cotton layer 4 is attached to the side panels 6 to block the ventilation holes 8. The fan 5 is rotatably arranged in the box body 1.

[0029] In this embodiment, the side plate 6 has a plurality of ventilation holes 8. Under normal conditions, the heat insulating cotton layer 4 is attached to the side plate 6 to block the ventilation holes 8. The heat insulating cotton layer 4 is made of heat insulating material, and while blocking, it also has the function of reducing noise, thereby isolating and blocking the sunlight, but it cannot block it 100%. To this end, when the temperature in the box body 1 reaches a preset value, the driving member installed in the box body 1 drives the transmission roller 2 to rotate, and the transmission roller 2 drives the transmission belt 3, thereby driving the heat insulating cotton layer 4 to move, pull the heat insulating cotton layer 4 apart, gradually separate from the side plate 6, and no longer block the ventilation holes 8. During the process, the fan 5 is driven to rotate, and the fans 5 on the two side plates 6 on the opposite sides cooperate with each other to generate convection in the box body 1. The gas passes through the ventilation holes 8 on the side plates 6, thereby accelerating the gas flow in the box body 1, taking away the heat on the components inside the box body 1, and thus reducing the temperature in the box body 1. It should be emphasized that, during the process of the heat insulating cotton layer 4 being separated from the side plate 6, the multiple ventilation holes 8 are gradually opened, and the heat insulating cotton layer 4 will always block a part of the ventilation holes 8, and all ventilation holes 8 can be connected with the outside world in succession through the movement of the heat insulating cotton layer 4. Then, as the transmission roller 2 rotates, the transmission belt 3 rotates with the heat insulating cotton layer 4 for several cycles, and then returns to the receiving gap 7 to restore the closed state, continue to maintain the temperature inside the box 1, and block the external high temperature.

[0030] Reference Figure 4~Figure 8 , also includes a motor 9, a bevel gear 10 and a bevel gear 2 11, the motor 9 is arranged in the box body 1, the bevel gear 10 and the bevel gear 2 11 are both rotatably arranged in the box body 1, the bevel gear 10 is coaxially arranged with the transmission roller 2, the bevel gear 2 11 is drivingly connected to the fan 5, the bevel gear 10 and the bevel gear 2 11 are meshed, and the bevel gear 10 is drivingly connected to the motor 9.

[0031] In this embodiment, in order to realize the linkage between the movement of the heat insulating cotton layer 4 and the rotation of the fan 5, a motor 9, a bevel gear 1 10 and a bevel gear 2 11 are provided. When the temperature in the box body 1 reaches a preset value, the motor 9 starts, drives the bevel gear 1 10 to rotate, thereby driving the transmission roller 2 to rotate. In addition, because the bevel gear 1 10 is meshed with the bevel gear 2 11, the bevel gear 2 11 is synchronously driven to rotate, thereby driving the fan 5 to rotate. Thus, when the heat insulating cotton layer 4 is pulled out of the accommodation gap 7, the fan 5 automatically rotates. After the heat insulating cotton layer 4 moves one circle and then resets, the heat in the box body 1 can be discharged.

[0032] Reference Figure 5~Figure 8 , and also includes a brush 12, which is arranged in the box body 1. After the driving roller 2 rotates, the thermal insulation cotton layer 4 passes through the brush 12 to clean the thermal insulation cotton layer 4.

[0033] In this embodiment, because the ventilation holes 8 on the side panel 6 are open, dust will accumulate on the heat insulating cotton layer 4 after long-term use. For this reason, a brush 12 is provided. When the transmission roller 2 drives the heat insulating cotton layer 4 to move, it will pass through and contact the brush 12. The brush 12 scratches the surface of the heat insulating cotton layer 4, thereby cleaning the accumulated dust.

When installing, the clamping plate 2 14 is opened, and the edge of the heat insulating cotton layer 4 is placed between the clamping plate 13 and the clamping plate 2 14, and then the clamping plate 2 14 is swung to make the clamping block 16 engage with the clamping groove 15, thereby clamping the heat insulating cotton layer 4. The clamping plate 13 and the clamping plate 2 14 are arranged in four groups, respectively clamping the four corners of the heat insulating cotton layer 4, thereby fixing the heat insulating cotton layer 4 on the transmission belt 3, and convenient for replacement.
