Description

Traditional distribution methods are difficult to meet the needs of modern power systems, and outdoor distribution cabinets have come into being. Distribution cabinets are a general term for motor control centers and are the final equipment in the distribution system. They are suitable for outdoor occasions with relatively dispersed loads and fewer circuits.

[0004] During the long-term use of outdoor distribution cabinets, dust in the air will also enter the distribution cabinet through the air inlet. Usually, a filter will be set at the air inlet for filtering. However, when the air is relatively humid, the humid air will wet the dust adhering to the filter. After the air dries, the dust will solidify on the surface of the filter, which can easily cause the filter to be blocked and reduce the heat dissipation effect in the distribution cabinet.

[0017] Compared with the prior art, the present invention provides an outdoor power distribution cabinet, which has the following beneficial effects:

[0018] 1. The outdoor power distribution cabinet can spray liquid in the opposite direction toward the air outlet surface of the filter by cleaning the liquid spray end of the liquid spray mechanism, which can effectively wash away the wet dust that has adhered to the surface of the filter and reduce the possibility of dust solidification, so as to ensure smooth air circulation of the filter and avoid the decrease of ventilation efficiency due to blockage, so that it can better filter impurities in the air and reduce the replacement frequency due to blockage, thereby extending the service life of the filter;

[0019] 2. The outdoor power distribution cabinet can scrape off the residues that may not be washed on the surface by fitting the tip of the scraper with the air inlet surface of the filter, thereby reducing the amount of impurities accumulated on the air inlet surface of the filter;

[0020] 3. The outdoor power distribution cabinet drives the dehumidification box to move from the dehumidification chamber to the outside through the electric telescopic rod, and abuts against the inner wall of the filter box. During this process, the gas from the outside entering the cabinet will pass through the circulation hole of the dehumidification box. The dehumidification raw material filled in the dehumidification box can be activated carbon. After the external moist gas passes through the activated carbon, it will absorb most of the water vapor in the air, thereby reducing the amount of water vapor in the air entering the cabinet and improving the dryness of the circulating gas.

[0021] 4. The outdoor power distribution cabinet seals the open end of the heat dissipation box. After sealing, the heat dissipation gas in the cabinet is transported to the second ventilation plate through the pipeline, and the electric telescopic rod drives the dehumidification box to move from the outside to the dehumidification chamber. The through hole opened on the second ventilation plate blows air toward the flow hole, so that the hot gas passes through the dehumidification box and contacts the activated carbon inside the dehumidification box. The hot gas evaporates the adsorbed water on the activated carbon for reuse;

[0022] 5. The outdoor distribution cabinet uses the jet holes on the jet plate to blow toward the surface of the top plate to clean the dust or impurities on the top plate. On the one hand, it can prevent dust or impurities from accumulating on the surface of the top plate and causing accumulation. On the other hand, it can prevent dust from mixing with rainwater on rainy days, maintain the cleanliness of rainwater, and improve the quality of the water source stored in the subsequent liquid storage tank. Then, the water source is used to backwash the air outlet surface of the filter, reduce the amount of dust in the water, and reduce the impact of backwashing on the filter.

[0023] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The present invention can perform reverse spraying toward the air outlet surface of the filter, which can effectively wash away the wet dust that has adhered to the surface of the filter and reduce the possibility of dust solidification, so as to ensure smooth air circulation of the filter and avoid the decrease in ventilation efficiency due to blockage, so that it can better filter impurities in the air and reduce the replacement frequency due to blockage, thereby extending the service life of the filter.

[0036] Example:

[0037] Reference Figure 1-Figure 9, an outdoor power distribution cabinet, comprising a cabinet 1, and also comprising: a filter box 2, fixedly connected to the side wall of the cabinet 1, wherein a filter screen 3 is fixedly connected to the filter box 2, and a partition plate 24 is fixedly connected in the cabinet 1, the partition plate 24 and the inner wall of the cabinet 1 form a diversion cavity, and the filter box 2 is connected to the diversion cavity; a cleaning spray mechanism is arranged in the filter box 2, and the spray end of the cleaning spray mechanism faces the air outlet surface of the filter screen 3; a first ventilation plate 12 and a second ventilation plate 13 are respectively fixedly connected to the inner wall of the filter box 2, and a dehumidification cavity is formed between the first ventilation plate 12 and the second ventilation plate 13, and a dehumidification interception mechanism is arranged in the dehumidification cavity; a top plate 26 is obliquely arranged at the top of the cabinet 1, and the top plate 26 and the cabinet 1 form a storage tank, wherein a placement cavity is formed between the top plate 26 and the cabinet 1, a liquid storage mechanism is arranged in the placement cavity, and the liquid storage mechanism is connected to the storage tank, and the spray end of the cleaning spray mechanism is connected to the liquid storage mechanism through a pipeline.

[0038] The cabinet 1 may be provided with electrical components such as circuit breakers, fuses, contactors, leakage protectors, and a monitoring system for realizing remote monitoring, data collection and analysis. It may also be provided with cables for connecting in and out to form a power distribution cabinet. A door is hingedly provided on the cabinet 1, and the door can close the cabinet 1 to make it in a sealed state to prevent outdoor impurities from entering the cabinet 1.

[0039] The filter 3 arranged in the filter box 2 can intercept impurities in the air entering the filter box 2. When the filter box 2 is in long-term use, dust in the air will also enter the cabinet 1 through the air inlet of the filter box 2, and the filter 3 can filter the dust in the air. However, when the air is relatively humid, especially on rainy days, the humid air will wet the dust adhering to the filter 3. After the air is dry, the dust will solidify on the surface of the filter 3, which can easily cause the filter 3 to be blocked.

[0040] By cleaning the liquid spray end of the liquid spray mechanism, liquid can be sprayed in the reverse direction toward the air outlet surface of the filter 3, which can effectively wash away the wet dust that has adhered to the surface of the filter 3 and reduce the possibility of dust solidification, so as to ensure smooth air circulation of the filter 3 and avoid the decrease in ventilation efficiency due to blockage, so that it can better filter impurities in the air and reduce the replacement frequency due to blockage, thereby extending the service life of the filter 3.

[0041] Furthermore, the above-mentioned cleaning spray mechanism includes a spray plate 5, a mounting box 7 is fixedly connected to the top of the filter box 2, a first screw rod 8 and a second screw rod 9 are rotatably connected in the mounting box 7, a first movable block 10 is threadedly connected to the first screw rod 8, a scraper 4 is fixedly connected to the bottom of the first movable block 10, and the tip of the scraper 4 is in contact with the air inlet surface of the filter 3, a second movable block 11 is threadedly connected to the second screw rod 9, the spray plate 5 is fixedly connected to the bottom of the second movable block 11, and the spray end of the spray plate 5 faces the air outlet surface of the filter 3.

[0042] Reference Figure 6-Figure 7 By rotating the first screw rod 8 and the second screw rod 9 in the installation box 7, the first movable block 10 and the second movable block 11 can be driven to move back and forth in the installation box 7, and the first movable block 10 and the second movable block 11 will move along the inner wall of the installation box 7, and the positions of the first movable block 10 and the second movable block 11 are not arranged correspondingly, so that the scraper 4 and the spray plate 5 can be staggered, and a diverter cavity is also provided in the spray plate 5, and a spray hole 6 is also provided on the side of the spray plate 5 facing the filter 3. The liquid in the diverter cavity can be sprayed to the outside through the spray hole 6, and when the spray plate 5 is working, the tip of the scraper 4 fits against the air inlet surface of the filter 3, and the residue that may not be washed on the surface is scraped off, thereby reducing the amount of impurities accumulated on the air inlet surface of the filter 3.

[0043] In order to facilitate the provision of liquid to the spray plate 5, the above-mentioned liquid storage mechanism further includes a liquid storage tank 28 fixedly connected to the placement cavity, and a water pump 29 is fixedly connected to the placement cavity. The input end of the water pump 29 is connected to the liquid storage tank 28 through a water inlet pipe, and the output end of the water pump 29 is connected to the spray plate 5 through a water outlet pipe.

[0044] The top plate 26 is tilted and arranged on the top of the cabinet 1. Figure 1 and Figure 2 As shown in the figure, when it rains, the inclined top plate 26 can protect the top of the cabinet 1 on the one hand to prevent rainwater from directly hitting the top of the cabinet 1, and on the other hand, it can also utilize the rainwater generated on rainy days. When rainwater falls on the top of the top plate 26, it will flow into the storage tank along the inclined top plate 26, and an interception net 30 is provided in the storage tank, and the interception net 30 and the storage tank form a filter tank. An inlet pipe 38 is provided on the liquid storage tank 28, and the input end of the inlet pipe 38 extends into the filter tank to cooperate with the interception net 30, and a one-way valve is provided on the inlet pipe 38. Large particles of impurities in the rainwater will be initially filtered by the interception net 30, and then the excess rainwater will be transported to the liquid storage tank 28 by the inlet pipe 38, thereby providing a water source for the spray plate 5.

[0045] In addition, the input end of the water pump 29 is connected to the liquid storage tank 28 through the water inlet pipe, and the output end of the water pump 29 is connected to the spray plate 5 through the water outlet pipe. After starting the water pump 29, the water source in the liquid storage tank 28 will be pressurized and transported to the spray plate 5.

[0046] In order to facilitate the rotation of the screw rod, a working box is fixedly connected to the outer wall of the filter box 2, and the ends of the first screw rod 8 and the second screw rod 9 extend to the working box respectively, and a first pulley 33 and a second pulley 34 are provided. The first pulley 33 and the second pulley 34 are connected by belt drive, and a booster disc 35 is fixedly connected to the working box, and a rotating shaft 36 is fixedly connected to the first pulley 33. The rotating shaft 36 extends to the booster disc 35 and is fixedly connected to a turbine blade 37. One side of the booster disc 35 is connected to the water outlet pipe through a telescopic tube, and the other side of the booster disc 35 is connected to the spray plate 5 through a telescopic tube.

[0047] When the water pump 29 is started, the water source in the liquid storage tank 28 will be pressurized and transported to one side of the booster disc 35. During this process, the turbine blades 37 in the booster disc 35 will be affected by the water flow and drive the rotating shaft 36 to rotate, thereby causing the rotating shaft 36 to drive the first pulley 33 to rotate synchronously, and the first pulley 33 will drive the second pulley 34 to rotate through the belt. At this time, the first screw rod 8 and the second screw rod 9 will rotate synchronously, and the other side of the booster disc 35 will transport the water source to the spray plate 5 through the telescopic tube, and the water source will enter the diversion chamber and then be sprayed out from the spray hole 6.

[0048] Furthermore, the above-mentioned dehumidification interception mechanism includes a dehumidification box 14, which is provided with a flow hole 15, and the dehumidification box 14 is filled with dehumidification raw materials. An electric telescopic rod 16 is fixedly connected to the side wall of the filter box 2, and the output end of the electric telescopic rod 16 extends to the dehumidification chamber where a connecting rod is provided. The dehumidification box 14 is fixedly connected to the connecting rod, and both sides of the dehumidification box 14 can be fitted with the outer walls of the first ventilation plate 12 and the second ventilation plate 13.

[0049] In addition, in order to reduce the impact of humid water vapor on the internal equipment of the cabinet 1, a humidity detector is also installed inside the filter box 2 to detect the air humidity inside the filter box 2. When the outside air is relatively humid, the electric telescopic rod 16 will drive the dehumidification box 14 to move from the dehumidification chamber to the outside and press against the inner wall of the filter box 2. During this process, the gas from the outside entering the cabinet 1 will pass through the circulation hole 15 of the dehumidification box 14, and the dehumidification raw material filled in the dehumidification box 14 can be activated carbon. After the external humid gas passes through the activated carbon, it will adsorb most of the water vapor in the air, thereby reducing the amount of water vapor in the air entering the interior of the cabinet 1 and improving the dryness of the circulating gas.

[0050] A negative pressure pump 27 is fixedly connected in the placement cavity, and the input end of the negative pressure pump 27 is connected with the filter box 2 through an air inlet pipe, and the air inlet pipe is arranged on one side of the air outlet surface of the filter 3, and is arranged on one side of the air outlet surface of the dehumidification box 14, while the output end of the negative pressure pump 27 is connected with the diversion cavity through the air outlet pipe, and an air hole 25 is also opened at the bottom of the partition plate 24. When the negative pressure pump 27 is started, the gas in the filter box 2 will be transported to the diversion cavity, and then the air hole 25 will transport the gas to the inside of the cabinet 1 to dissipate heat for the equipment inside the cabinet 1.

[0051] In order to facilitate the drying of the activated carbon, a heat dissipation box 19 is fixedly connected to the side wall of the cabinet 1, and a sealing plate 21 is lifted and lowered inside the heat dissipation box 19. The heat dissipation box 19 is connected to the second ventilation plate 13 through a pipeline. A jet plate 31 is fixedly connected to the top plate 26, and a jet hole 32 is opened on the jet plate 31. The first ventilation plate 12 is connected to the jet plate 31 through a pipeline.

[0052] When the sealing plate 21 moves toward the bottom of the heat dissipation box 19 , the air outlet of the heat dissipation box 19 will be closed. At this time, the gas after the heat dissipation in the cabinet 1 will be transported to the second ventilation plate 13 through the pipeline.

[0053] It needs to be explained that a boost cylinder 17 is fixedly connected to the filter box 2, a boost rod 18 is slidably connected to the boost cylinder 17, a piston is provided at one end of the boost rod 18, and the piston fits against the inner wall of the boost cylinder 17, the other end of the boost rod 18 is fixedly connected to the dehumidification box 14, a fixed box 20 is fixedly connected to the heat dissipation box 19, a guide cylinder 23 is fixedly connected to the top of the fixed box 20, a guide rod 22 is slidably connected to the guide cylinder 23, a piston is provided at one end of the guide rod 22, and the piston fits against the inner wall of the guide cylinder 23, the other end of the guide rod 22 is fixedly connected to the sealing plate 21, and the boost cylinder 17 is connected to the guide cylinder 23 through a telescopic tube.

[0054] When the electric telescopic rod 16 drives the dehumidification box 14 to move from the dehumidification chamber to the outside, the booster rod 18 will move synchronously, thereby driving the piston to move in contact with the position of the guide cylinder 23, so that negative pressure is generated in the booster cylinder 17, and the gas in the guide cylinder 23 is transported to the booster cylinder 17 through the pipeline. At this time, the piston on the guide rod 22 will move in contact with the inner wall of the guide cylinder 23, and the guide rod 22 drives the sealing plate 21 at the bottom to move synchronously, so that the heat dissipation box 19 is in a circulation state, and the high-temperature gas in the cabinet 1 is discharged to the outside, and a dustproof net is also provided in the heat dissipation box 19 to prevent external impurities from entering the cabinet 1.

[0055] When the humidity detector detects that the air entering the filter box 2 is relatively dry, the electric telescopic rod 16 will drive the dehumidification box 14 to enter the dehumidification chamber from the outside, and the two sides of the dehumidification box 14 will fit the outer walls of the first ventilation plate 12 and the second ventilation plate 13 respectively. During this process, the boost rod 18 will move synchronously, so that the piston on the boost rod 18 will move in contact with the position of the guide cylinder 23, and the gas in the boost cylinder 17 will be transported to the guide cylinder 23. At this time, the piston on the guide rod 22 will move in contact with the inner wall of the guide cylinder 23, so that the sealing plate 21 moves toward the inner wall of the heat dissipation box 19, and the open end of the heat dissipation box 19 is blocked. After blocking, the heat dissipation gas in the cabinet 1 will be transported to the second ventilation plate 13 through the pipeline.

[0056] In addition, through holes are respectively provided on the first ventilation plate 12 and the second ventilation plate 13, and both groups of through holes are oriented toward the circulation hole 15. The through holes provided on the second ventilation plate 13 will blow air toward the circulation hole 15, so that the hot gas passes through the dehumidification box 14 and contacts the activated carbon inside the dehumidification box 14. The hot gas will evaporate the adsorbed water on the activated carbon for reuse, and then be transported to the first ventilation plate 12. The evaporated gas in the first ventilation plate 12 is then transported to the jet plate 31 through a pipeline, and then the jet holes 32 on the jet plate 31 are used to blow toward the surface of the top plate 26, thereby cleaning the dust or impurities on the top plate 26. On the one hand, it can prevent dust or impurities from accumulating on the surface of the top plate 26 and causing accumulation. On the other hand, it can also prevent dust from mixing with rainwater on rainy days, maintain the cleanliness of rainwater, and improve the quality of the water source stored in the subsequent liquid storage tank 28, and then use the water source to backwash the air outlet surface of the filter 3, reduce the amount of dust in the water, and reduce the impact of backwashing on the filter 3.
