Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a visual intelligent heat dissipation opening and closing device. Background Art

[0002] The distribution cabinet is equipped with wires, leakage protectors, busbars, disconnectors and other equipment. When the power load is large, it will generate heat. The distribution cabinet is installed outdoors and is in a closed state. During long-term operation, the equipment cannot dissipate heat normally, and the accumulated heat causes the equipment temperature to rise, which can easily cause equipment burnout, power outages in the substation area, and reduce the reliability of the power supply of the power grid.

[0003] When the temperature is high, some distribution cabinets in some areas will open their doors to dissipate heat during peak hours. If they run in this state for a long time, rain, snow, moisture, dust, and some organisms that enter the distribution cabinet will corrode the surface of the distribution equipment, causing equipment aging, reduced insulation performance, and reduced power supply reliability. At the same time, there are safety hazards and fire accidents.

[0004] At present, most distribution cabinets adopt natural air cooling, which mainly uses fluid convection to dissipate heat, has low heat dissipation efficiency, and it is difficult to grasp the temperature state of the distribution cabinet under operating conditions.

[0005] Based on the retrieval of the above information, it can be seen that the heat dissipation method of the existing distribution cabinet is relatively single, and it is impossible to flexibly adjust according to environmental changes to ensure the normal operation of the distribution cabinet. For this reason, a visual intelligent heat dissipation opening and closing device is proposed, which can close the air circulation channel between the distribution cabinet and the outside world in rainy and snowy weather, and ensure the effective heat dissipation of the distribution cabinet by air convection in non-rainy and snowy weather.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-6 , the embodiment of the present invention provides the following technical solutions: Embodiment 1: A visual intelligent heat dissipation opening and closing device comprises a power distribution cabinet 1, two cabinet doors 102 are hinged on the front of the power distribution cabinet 1, and a plurality of heat dissipation holes 101 are provided on both sides of the power distribution cabinet 1. In order to reduce the influence of direct sunlight on the internal temperature of the power distribution cabinet 1, a heat insulation box 3 is fixedly installed on the top of the power distribution cabinet 1.

[0023] As a preferred solution, in order to achieve the opening and closing management of the heat dissipation hole 101, heat dissipation opening and closing components 2 are provided on both sides of the inner cavity of the distribution cabinet 1. Specifically, the heat dissipation opening and closing components 2 include a sealing plate 201, and a guide hole 202 used in conjunction with the heat dissipation hole 101 is provided on the surface of the sealing plate 201. One side of the sealing plate 201 is in sliding contact with one side of the inner cavity of the distribution cabinet 1, and a heat dissipation fan 203 is fixedly installed on the other side of the sealing plate 201 through a bracket, and an L-shaped plate 204 is fixedly installed on the top of the sealing plate 201. At this time, the opening and closing control of the heat dissipation hole 101 can be achieved by controlling the lifting and lowering of the sealing plate 201.

[0024] Furthermore, in order to realize convenient lifting and lowering control of the sealing plate 201, a lifting and lowering adjustment component 4 is fixed at the bottom of the inner cavity of the heat insulation box 3, and the lifting and lowering adjustment component 4 includes an electric telescopic rod 401, and the electric telescopic rod 401 is fixedly installed at the bottom of the inner cavity of the heat insulation box 3. A push plate 402 is fixedly installed at the telescopic end of the electric telescopic rod 401, and plug plates 403 are fixedly installed on both sides of the bottom of the push plate 402. The bottom of the plug plate 403 passes through the heat insulation box 3 and is fixedly connected to the top of the L-shaped plate 204. In this way, by controlling the extension and retraction of the electric telescopic rod 401, the opening and closing control of the heat dissipation hole 101 can be realized.

[0025] As a detailed description, in rainy and snowy weather, the electric telescopic rod 401 can be controlled to retract to block the heat dissipation hole 101, thereby preventing humid air from directly entering the distribution cabinet 1 in rainy and snowy weather and affecting the normal use of components.

[0026] Embodiment 2. This embodiment is an improvement of the previous embodiment, a visual intelligent heat dissipation opening and closing device, and also includes a heat dissipation fin 5 and an acceleration traction component 6, wherein the heat dissipation fin 5 includes a plurality of fins 501, and the fins 501 are made of aluminum material. Rubber waterproof strips 502 are fixedly installed on both sides of the heat insulation box 3. The rubber waterproof strips 502 can be used to wipe the fins 501 received in the heat insulation box 3 to prevent the fins 501 from bringing water into the heat insulation box 3. One side of the plurality of fins 501 passes through the heat insulation box 3 and the rubber waterproof strips 502 in sequence. Two baffles 301 are fixedly installed on both sides of the bottom of the inner cavity of the heat insulation box 3, and the tops of the two baffles 301 are in sliding contact with the bottom of the fins 501, and the other sides of the plurality of fins 501 are commonly fixedly connected with a connecting plate 503, and one side of the connecting plate 503 is also fixedly installed with two first tooth plates 504.

[0027] As a preferred solution, in order to ensure the heat dissipation of the distribution cabinet 1 after the heat dissipation holes 101 are closed and blocked, a ventilation groove 302 is opened at the bottom of the inner cavity of the heat insulation box 3 and between the two baffles 301 arranged in the middle, and the acceleration traction component 6 includes two docking plates 601 and two second tooth plates 602. The two docking plates 601 are fixedly installed on one side of the top of the heat insulation box 3, and the two second tooth plates 602 are respectively fixedly installed on the front and rear sides of the push plate 402. A large tooth roller 603 and a small gear 604 are installed on the opposite side of the two docking plates 601 in sequence from top to bottom. The large tooth roller 603 is meshed with the small gear 604, and the two second tooth plates 602 are respectively meshed with the two large tooth rollers 603, and the small gear 604 is meshed with the first tooth plate 504.

[0028] In this way, when the electric telescopic rod 401 contracts and the sealing plate 201 closes and seals the heat dissipation hole 101, the heat dissipation fins 5 can be driven to extend to the outside of the heat insulation box 3 by accelerating the traction component 6, so that the fins 501 can accelerate the heat dissipation speed inside the distribution cabinet 1.

[0029] The advantage of the second embodiment over the first embodiment is that after the heat dissipation holes 101 are closed, effective heat dissipation of the power distribution cabinet 1 can be ensured.

[0030] As an optional embodiment, a first temperature sensor 7 is fixedly installed on the top of the push plate 402, a visual control panel 8 is inlaid and fixed on the surface of a cabinet door 102, and a rain and snow sensor 9 and a second temperature sensor 10 are fixedly installed on both sides of the top of the heat insulation box 3. The visual control panel 8 is used in conjunction with the first temperature sensor 7, the rain and snow sensor 9, the second temperature sensor 10, the cooling fan 203 and the electric telescopic rod 401, respectively. The rain and snow sensor 9 uses an RS485 rain and snow sensor, and the first temperature sensor 7 and the second temperature sensor 10 use a MAX31865 temperature sensor.

[0031] The method of using the above device includes: S1. When the rain and snow sensor 9 detects rain and snow around the distribution cabinet 1, it continuously sends rain and snow weather instructions to the visual control panel 8. After receiving the rain and snow weather instructions, the visual control panel 8 controls the cooling fan 203 to be turned off, and at the same time controls the electric telescopic rod 401 to shrink the set distance. The electric telescopic rod 401 pulls the push plate 402 to make the plug plate 403 drop, and the plug plate 403 pushes the L-shaped plate 204 to make the blocking plate 201 drop. During the process, the guide hole 202 is separated from the heat dissipation hole 101 until the blocking plate 201 completes the blocking of the heat dissipation hole 101.

[0032] During the descending process of the push plate 402, the second tooth plate 602 is driven to descend, and the second tooth plate 602 drives the large tooth roller 603 to rotate, and the large tooth roller 603 drives the small gear 604 to accelerate the rotation, and the small gear 604 pushes the first tooth plate 504 to move, and the first tooth plate 504 pushes the connecting plate 503 to move several fins 501 to the outside of the heat insulation box 3. When the electric telescopic rod 401 stops contracting, part of the fins 501 are located outside the heat insulation box 3, and part of the fins 501 are located inside the heat insulation box 3. The hot air generated inside the distribution cabinet 1 rises, passes through the air vents 302 and enters the heat insulation box 3, and the fins 501 are used for heat dissipation.

[0033] S2. After the visual control panel 8 does not obtain the rainy or snowy weather instruction within the set time, the set time is preferably 1 hour, the cooling fan 203 is turned on, and the electric telescopic rod 401 is controlled to extend the set distance at the same time. The electric telescopic rod 401 squeezes the push plate 402 to make the plug plate 403 rise, and the plug plate 403 pulls the L-shaped plate 204 to make the blocking plate 201 rise until the guide hole 202 is completely connected with the heat dissipation hole 101.

[0034] During the rising process of the push plate 402, the second tooth plate 602 is driven to rise, and the second tooth plate 602 drives the large tooth roller 603 to rotate, and the large tooth roller 603 drives the small gear 604 to accelerate the rotation, and the small gear 604 pushes the first tooth plate 504 to move, and the first tooth plate 504 pushes the connecting plate 503 to move several fins 501 into the insulation box 3. During the process, the rubber water-proof strip 502 wipes the fins 501 on the outside of the insulation box 3. When the electric telescopic rod 401 stops extending, the fins 501 are completely immersed in the rubber water-proof strip 502.
