TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment, and particularly relates to an electrical cabinet convenient to maintain. BACKGROUND

[0002] The electrical cabinet is a cabinet body made of steel for protecting electrical elements to work normally. The electrical cabinet adopts a heat dissipation mode, that is, air holes are arranged at the side wall of the cabinet body, and hot air is forced to be discharged from the cabinet body to the outside to achieve the purpose of heat dissipation. However, when the electrical cabinet is applied outdoors, there is a risk of being flooded. When the lower part of the electrical cabinet is flooded, water will enter the cabinet body from the air holes in the side wall of the electrical cabinet, thereby affecting the normal use of the electrical cabinet.

[0003] Meanwhile, water vapor in the air is easy to make the electrical elements damp, so that a drying bag is usually arranged inside the cabinet body for absorbing water in the air. When the drying agent is used for a long time, the water absorption is full, and the drying capacity is reduced. In order to ensure the subsequent drying effect, the drying agent needs to be replaced regularly, which is very troublesome. In addition, the filter screen for filtering dust in the air also needs to be cleaned frequently by manual operation, which is inconvenient to maintain. SUMMARY

[0009] More preferably, it further includes condensation plate and second guide plate;Two condensation plates are fixedly connected to the upper side of the inside of the vent cover and inclined to the side of the connecting frame;A second guide plate is fixedly connected to the upper side of each connecting frame, and the second guide plate is spaced apart from the condensation plate;An inlet groove is formed in the upper side of each connecting frame.

[0010] More preferably, it further includes water guide plate;A water guide plate is connected to each connecting frame, and the water guide plate is inclined downward.

[0011] More preferably, sealing strip is arranged on the through groove.

[0012] More preferably, a temperature and humidity sensor is arranged on the cabinet door.

[0013] More preferably, the top of the ventilation cover is conical, and a rain baffle is arranged on the upper side of the ventilation opening.

[0014] More preferably, the cabinet further comprises a storage box, a fire extinguishing tank and a powder spraying cylinder; a smoke sensor is arranged in the cabinet; the cabinet is fixedly connected with the storage box; the storage box is provided with the fire extinguishing tank; the cabinet is fixedly connected with the powder spraying cylinder on the upper side; the powder spraying cylinder is provided with a plurality of powder spraying openings on the lower side; and the fire extinguishing tank is communicated with the powder spraying cylinder through a pipeline.

[0015] The beneficial effects are: when the cabinet is applied outdoors and flooded, the sealing strip at the edge of the cabinet door ensures the sealing between the cabinet and the cabinet door, and the cabinet side wall is not provided with a ventilation hole, so that the cabinet and the cabinet door can block the water, ensuring the normal operation of the electrical elements in the cabinet, and distinguishing from the prior art, the present application can also normally perform heat dissipation work while preventing water from entering the cabinet;

[0016] Through the baffle structure formed by the plurality of staggered support plates, and each support plate is located between the two first ventilation holes distributed vertically, the airflow in the ventilation plate will first contact the support plate and then blow from the first ventilation hole to the electrical elements, so that the water-absorbing fiber plate fully absorbs the water in the air to avoid the water vapor in the air entering the cabinet, causing the electrical elements in the cabinet to be damp;

[0018] When the water-absorbing fiber plate containing water is dried by the outside air and the hot air emitted by the electrical elements running, the support plates arranged in a staggered and downward inclined manner can cause a certain blockage disturbance to the upward flowing hot air, so that the hot air can fully contact the water-absorbing fiber plate, to enhance the drying effect of the hot air on the water-absorbing fiber plate;

[0019] When the water-absorbing fiber plate is dried by the outside air and the hot air emitted by the electrical elements running, the gas carrying water vapor contacts the condensing plate in a normal temperature state, part of the water vapor condenses on the surface of the condensing plate to form liquid drops, when the liquid drops accumulate a certain amount, under the action of gravity, flow to the upper side of the connecting frame along the inclined condensing plate and drop downward, then guided by the second guide plate, pass through the water inlet groove, and wash the surface of the filter screen, so as to further ensure the cleaning effect of the filter screen in cooperation with the exhaust gas flow.

[0038] A temperature and humidity sensor is arranged on the cabinet door 1001.

[0039] The top of the ventilation cover 2 is conical, and a rain shield is arranged on the upper side of the ventilation port 2002, so as to guide the rainwater when it rains and avoid the rainwater entering the ventilation cover 2 from the ventilation port 2002.

[0040] The following description takes Figure 1 as the perspective reference, wherein the side where the cabinet door 1001 is located is the front side;

[0041] In the use of the present application, the cabinet door 1001 is in a closed state, and the sealing strip at the edge of the cabinet door 1001 ensures the sealing between the cabinet body 1 and the cabinet door 1001, at this time each through slot 1002 is communicated with the communication port 4001 of the corresponding air panel 4, the second air hole 4003 on the initial left air panel 4 is blocked by the baffle 8, the first air hole 4002 is aligned with the vertical slot 8001, and the first air hole 4002 on the right air panel 4 is blocked by the baffle 8, the second air hole 4003 is aligned with the vertical slot 8001, when the heat dissipation work is needed, the fan 3001 on the left connecting plate 3 is rotated to make the outside air enter the left chamber of the air cover 2 from the air inlet 2002, then pass through the connecting plate 3, the through slot 1002, the communication port 4001, the first air hole 4002 and the vertical slot 8001 in turn, and blow to the electrical elements in the cabinet body 1 for heat dissipation, at the same time, the right fan 3001 is rotated to drive the outside air entering the cabinet body 1 and the heat generated by the electrical elements to enter the second air hole 4003 of the right air panel 4, then pass through the communication port 4001, the through slot 1002, the connecting plate 3 and the air inlet 2002 in turn, and then discharge out of the cabinet body 1, thereby forming an air circulation loop in the cabinet body 1 to dissipate heat in the cabinet body 1, in this way, when the present application is applied to outdoor waterlogging, the sealing strip at the edge of the cabinet door 1001 ensures the sealing between the cabinet body 1 and the cabinet door 1001, and the side wall of the cabinet body 1 is not provided with a breathable hole, so that the cabinet body 1 and the cabinet door 1001 can block water to ensure the normal operation of the electrical elements in the cabinet body 1, and the present application can also normally perform heat dissipation work while preventing water from entering the cabinet body 1.

[0042] It should be noted that when the outside air enters the air panel 4, it will first contact the water-absorbing fiber plate 5, and then blow out from the first air hole 4002, and the air flow in the air panel 4 will first contact the baffle plate 5001, and then blow to the electrical elements from the first air hole 4002, so that the water in the air is fully adsorbed by the water-absorbing fiber plate 5 to avoid the water in the air entering the cabinet body 1, causing the electrical elements in the cabinet body 1 to be damp.

[0043] It should be noted that the inner diameter of the first air hole 4002 increases from top to bottom, so that the air flow flows downward in the air panel 4, and the difficulty of blowing out from the first air hole 4002 gradually decreases from top to bottom when the air flow blows out from the first air hole 4002, so that the air flow can flow downward to blow out from the first air hole 4002 at the lower side, so that the air flow can flow through all the first air holes 4002 and fully contact the water-absorbing fiber plate 5.

[0044] It should be noted that when dissipating heat, since the right air baffle 4 does not blow air to the area directly opposite to it, in order to ensure the heat dissipation effect of the electrical components in this area, when the inside of the cabinet 1 is blown and dissipated by the first air holes 4002 of the left air baffle 4, the air flow blown out by part of the first air holes 4002 can be guided to the right by the first guide plate 8002, so that part of the air flow can be blown to the right, so that the air flow blown out by the first air holes 4002 can cover all areas inside the cabinet 1, which is beneficial to ensure the heat dissipation effect of the electrical components.

[0045] It should be noted that when the outside air enters the air cover 2 from the air inlet 2002, the air is filtered by the filter screen 9001 to prevent dust and other impurities in the air from entering the cabinet 1.

[0046] Further, after the present application is used for a period of time, when the temperature and humidity sensor on the cabinet door 1001 detects that the humidity inside the cabinet 1 rises, it can be known that the water-absorbing fiber plate 5 in the left air baffle 4 has a decreased water-absorbing capacity due to the absorption of a large amount of water. At this time, the electric sliding block 7 can be controlled to drive the corresponding baffle 8 to translate along the sliding rail 6, so that the first air hole 4002 on the left air baffle 4 is blocked by the baffle 8, the second air hole 4003 is aligned with the vertical groove 8001, and the second air hole 4003 on the right air baffle 4 is blocked by the baffle 8, the first air hole 4002 is aligned with the vertical groove 8001. At the same time, the two fans 3001 are controlled to reverse, so that the left fan 3001 performs exhaust work and the right fan 3001 performs air suction work. At this time, the air flow is blown out through the first air hole 4002 on the right air baffle 4, the outside air and the hot air generated by the operation of the electrical components flow into the second air hole 4003 on the left air baffle 4, and are discharged outward. At this time, the water-absorbing fiber plate 5 in the right air baffle 4 can absorb water, and the water-absorbing fiber plate 5 in the left air baffle 4 can be dried by the hot air generated by the operation of the electrical components and the air blown outward, and the dust attached to the left filter screen 9001 can be blown away by the air blown to the left filter screen 9001. Thus, the drying and self-cleaning of the water-absorbing fiber plate 5 and the filter screen 9001 are realized at the same time, without the need for manual replacement or cleaning operation, which effectively facilitates maintenance.

[0047] Further, when the outside air and the heat emitted from the operation of the electrical elements flow upward from the second air hole 4003 to the communication port 4001, the heat flowing upward can be disturbed by the branch plates 5001 arranged in a staggered and downward inclined manner, so that the heat can fully contact the water-absorbing fiber plate 5, thereby enhancing the air-drying effect of the water-absorbing fiber plate 5 by the outside air and the heat emitted from the operation of the electrical elements. When the water-absorbing fiber plate 5 is air-dried by the outside air and the heat emitted from the operation of the electrical elements, the gas carrying water vapor contacts the condensing plate 101 in a normal temperature state, and part of the water vapor condenses on the surface of the condensing plate 101 to form liquid drops. When the liquid drops accumulate to a certain amount, they will flow to the upper side of the connecting frame 9 along the inclined condensing plate 101 under the action of gravity and then drip downward. Then, under the guidance of the second guide plate 102, the dirty water passes through the water inlet groove 9002 to clean the surface of the filter screen 9001, thereby further ensuring the cleaning effect of the filter screen 9001 in cooperation with the exhaust air flow.

[0048] In order to avoid the dirty water for cleaning the surface of the filter screen 9001 from accumulating on the upper side of the cabinet 1, the water guide plate 103 arranged in a downward inclined manner is used to guide the dirty water, so that the dirty water flows out to the outside under the guidance of the water guide plate 103.

[0049] Embodiment 2

[0050] Based on the embodiment 1, as shown in Figure 7 The cabinet 1 is provided with a smoke sensor, and the cabinet 1 is fixedly connected with a storage box 201. The storage box 201 is provided with a fire extinguishing tank 202. The cabinet 1 is fixedly connected with a powder spraying cylinder 203 on the upper side, and the powder spraying cylinder 203 is provided with a plurality of powder spraying ports on the lower side. The fire extinguishing tank 202 is communicated with the powder spraying cylinder 203 through a pipeline, and an electromagnetic valve is arranged on the pipeline. The electromagnetic valve is electrically connected with the smoke sensor.

[0051] In the present application, the fan 3001 and the electric sliding block 7 are powered by independent power sources.

[0052] When the smoke sensor in the cabinet 1 detects that there is smoke, that is, the electrical elements in the cabinet 1 are short-circuited and on fire, the electromagnetic valve on the pipeline of the fire extinguishing tank 202 is opened, so that the fire extinguishing dry powder in the fire extinguishing tank 202 flows to the powder spraying cylinder 203, and then the fire extinguishing dry powder is sprayed downward from the powder spraying cylinder 203 to extinguish the electrical elements in the cabinet 1, so as to simultaneously control the electric sliding block 7 to drive the corresponding baffle 8 to translate until the baffle 8 blocks the first air holes 4002 on the two air holes 4, and the second air holes 4003 are aligned with the vertical grooves 8001, then control the two fans 3001 to work to exhaust the air in the cabinet 1 to the outside of the cabinet 1, and at the same time, when the electrical elements in the cabinet 1 are relatively dense, the downward falling of the fire extinguishing dry powder sprayed by the powder spraying cylinder 203 will be blocked to a certain extent, at this time, the downward flowing air current generated in the cabinet 1 through the second air holes 4003 suction promotes the downward falling of the fire extinguishing dry powder, so that the fire extinguishing dry powder can cover all areas in the cabinet 1 as soon as possible, effectively ensuring the speed of extinguishing fire.

Any equivalent replacement within the principles of the present application shall be included in the protection scope of the present application. The contents not described in detail in the present application belong to the prior art known by the technical personnel in the field.
