Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage switch cabinets, and particularly to an outdoor high-voltage switch cabinet suitable for plateau areas. Background Art

[0002] A high-voltage switch cabinet is a set of power transmission and distribution electrical equipment installed in a metal or non-metal insulated cabinet body or made into a prefabricated sectionalized ring network power supply unit. It is used in a ring distribution network to improve power supply reliability. When a line fails, power can be continued to be supplied to users from another line through the switch of the switch cabinet. Moreover, it generally adopts a combination of a load switch and a fuse, which can effectively avoid huge damage to equipment caused by faults such as short circuits.

[0003] When a traditional outdoor high-voltage switch cabinet is used in a plateau area, due to the large amount of sand and dust in the plateau area, dust is likely to accumulate on the surface of the switch cabinet. And due to the special plateau environment, the temperature difference between day and night in the plateau area is large, the sunlight radiation is strong during the day, the heat generated by the operation of the switch cabinet plus the external high temperature easily makes the equipment temperature too high. Moreover, personnel operations are easily affected by altitude sickness, increasing the risk and cost of cleaning work.

[0004] Therefore, it is necessary to provide an outdoor high-voltage switch cabinet suitable for plateau areas to solve the above technical problems. Summary of the Invention

[0016] Compared with the related art, the outdoor high-voltage switchgear applicable to the plateau area provided by the present invention has the following beneficial effects:

[0017] The present invention provides an outdoor high-voltage switchgear applicable to the plateau area. Through the cooperation of the first servo motor, the water diversion plate, the first screw rod, the first guide rod, the lifting support frame, the first water pump, the first pipeline and the first water suction pipe, since heat is generated during the operation of the high-voltage switchgear, especially in summer or during high-load operation periods, when the lifting support frame rises and falls, heat can be effectively removed by spraying water, so that the equipment is maintained within a suitable working temperature range, ensuring the stability of its electrical performance and reducing the risk of failures that may be caused by overheating. Secondly, the switchgear is outdoors, and dust, dirt and other impurities are likely to accumulate on the surface. Spraying water can regularly wash the switchgear to keep the surface of the equipment clean and prevent dust and other pollutants from affecting the heat dissipation and insulation performance of the equipment; through the cooperation of the cleaning rubber roller, the first rotating rod, the second rotating rod, the roller, the first gear, the third gear and the guide groove, the cleaning rubber roller can closely fit the outer wall of the high-voltage switchgear during the lifting process. For some stubborn stains or dirt that is firmly adhered, through the wiping and squeezing of the cleaning rubber roller, it can be more effectively removed in cooperation with the first pipeline. The two steps of spraying water for cleaning and wiping and cleaning are completed simultaneously during one lifting process without being carried out separately, thereby reducing the time and workload of the cleaning equipment and making the cleaning work more efficient;

[0018] Through the cooperation of the second filter screen, the movable frame, the support plate, the pressure sensor, the spring, the connecting plate, the lifting plate, the second servo motor, the second screw rod, the third guide rod and the sliding groove, the second filter screen can effectively intercept dust and prevent it from entering the water collecting tank in large quantities. When the dust on the second filter screen reaches a certain weight, it can be automatically tilted and poured out, so as to ensure that the filter screen can continuously and effectively play a filtering role and avoid excessive accumulation of dust. Secondly, by automatically pouring out the impurities, the number of times of manual regular cleaning and the required labor cost can be greatly reduced; through the cooperation of the rack, the first bevel gear, the second bevel gear, the third screw rod, the connecting rod, the scraper, the second gear and the second guide rod, when the second filter screen tilts and pours out dust and impurities, the scraper can further remove the dirt remaining on the filter screen. Since some dust will adhere to the mesh holes or the surface of the filter screen, the scraper can effectively scrape off these stubborn stains, making the filter screen cleaner and preventing dust from accumulating in the mesh holes of the filter screen and causing blockage, thereby affecting the collection and flow of rainwater;

[0019] Through the cooperation of the second water pump, the filter box, the second water suction pipe, the fan, the activated carbon fiber net, the drainage hole, the second dustproof net, the second pipe, the second water inlet hole and the first water inlet hole, the activated carbon fiber net has a strong adsorption capacity and can effectively adsorb harmful gases and impurities in the air. The water mist sprayed from the second pipe can wash away the dust and impurities adsorbed on the activated carbon fiber net, so that the filter maintains good adsorption performance and avoids the filter being clogged by dust and other impurities, affecting its adsorption efficiency. Secondly, the continuous water spraying can take away some heat, which helps to reduce the air temperature around the switch cabinet, and can also maintain the temperature and humidity inside the switch cabinet body. Keeping the air moist can reduce the risk of fire around the switch cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0043] The present invention will be further described below in conjunction with the accompanying drawings and the implementation mode.

[0044] First embodiment:

[0045] Please refer to Figures 1 - 5, in the first embodiment of the present invention, an outdoor high-voltage switchgear applicable to plateau areas includes: a waterproof top plate 1, a switchgear body 10, and a first dust-proof net 6. The waterproof top plate 1 is fixedly installed on the top of the switchgear body 10. Ventilation openings are provided on both sides of the switchgear body 10, and the first dust-proof net 6 is fixedly installed in the ventilation openings. Two water collecting troughs 7 and two water guiding troughs 52 are fixedly installed at the bottom of the switchgear body 10. Both ends of the water guiding trough 52 are respectively communicated with the two water collecting troughs 7. Two first screw rods 5 are rotatably installed on the top of the water collecting trough 7. A first servo motor 14 is fixedly installed on the waterproof top plate 1. The output shaft of the first servo motor 14 extends to the bottom of the waterproof top plate 1 and is fixedly connected to the top end of the first screw rod 5. The same lifting support frame 15 is threadedly connected to the outer sides of the two first screw rods 5. The first rotating rod 19 and two second rotating rods 20 are rotatably installed on the inner walls of three sides of the lifting support frame 15. A cleaning rubber roller 17 is fixedly installed on the outer side of the first rotating rod 19. When the cleaning rubber roller 17 rolls on the outer wall of the switchgear body 10, the outer wall of the switchgear body 10 can be evenly cleaned and cooled by the water sprayed by multiple sprinkler nozzles. Two rollers 21 are fixedly installed on the outer sides of the two second rotating rods 20. Two third gears 51 are fixedly installed on the outer side of the first rotating rod 19. A first gear 22 is fixedly installed on the outer side of the second rotating rod 20. The first gear 22 meshes with the third gear 51. Three first pipes 3 are fixedly installed on the outer walls of three sides of the lifting support frame 15. When the lifting support frame 15 moves up and down, it can be regularly cleaned through the first pipe 3, so that the appearance of the switchgear body 10 remains clean and tidy, avoiding stains and dust containing corrosive components from adhering to the outer wall for a long time and corroding the shell material of the switchgear body 10. Multiple sprinkler nozzles are fixedly installed on the first pipe 3. Three first water pumps 2 are also fixedly installed on the lifting support frame 15. The water inlet end of the first water pump 2 is fixedly installed with a first water suction pipe 4. The other end of the first water suction pipe 4 extends into the water collecting trough 7. One end of the first pipe 3 is fixedly connected to the water outlet end of the first water pump 2. The bottom ends of the two first pipes 3 located on the left and rear sides of the switchgear body 10 extend into the left water collecting trough 7, and the bottom end of the first pipe 3 located on the right side of the switchgear body 10 extends into the right water collecting trough 7.

[0046] Two first guide rods 9 are fixedly installed on the top of the water collecting trough 7, and both ends of the lifting support frame 15 are respectively slidably installed on the two first guide rods 9.

[0047] Multiple guide grooves 23 are provided on the outer wall of the switchgear body 10, and the outer wall of the roller 21 is in contact with the guide groove 23.

[0048] Two water diversion plates 12 are fixedly installed in the water collecting tank 7. Through the water diversion plates 12, rainwater can be diverted to both sides of the switch cabinet body 10, making it more convenient for the water collecting tank 7 to store rainwater. The water diversion plates 12 are provided with two inclined surfaces. A first filter screen 13 is also fixedly installed on the water collecting tank 7. The first filter screen 13 can initially filter the rainwater to prevent a large amount of impurities from entering the water collecting tank 7. When the impurities accumulate too much, they can be cleaned manually.

[0049] The working principle of the outdoor high-voltage switch cabinet applicable to the plateau area provided by the present invention is as follows:

[0050] In rainy days, the water collecting tank 7 can collect a large amount of rainwater. Through the water diversion plates 12 and the water diversion tank 52, the rainwater can be further introduced and concentrated in the two water collecting tanks 7. When dust and impurities adhere to the outer wall of the switch cabinet body 10, two first servo motors 14 are started. The two first servo motors 14 drive two first screws 5 through the output shafts to make the lifting support frame 15 lift and lower. Then, the first water pump 2 is started. The first water pump 2 pumps the rainwater collected in the water collecting tank 7 through the first water suction pipe 4 and conveys it into the first pipeline 3. At this time, a plurality of sprinkler nozzles on one side of the first pipeline 3 spray water to wash the outer wall of the switch cabinet body 10, and can also effectively take away heat.

[0051] When the lifting support frame 15 lifts and lowers, the rollers 21 roll in the guide grooves 23 and are engaged by two first gears 22 to drive the cleaning rubber roller 17 to rotate. The cleaning rubber roller 17 is attached to the outer wall of the switch cabinet body 10 and wipes and extrudes the outer wall during rotation, cooperating with the first pipeline 3 to more effectively remove dirt. In one lifting process, the two steps of spraying and cleaning and wiping and cleaning are completed simultaneously without the need to be carried out separately.

[0052] Compared with the related technology, the outdoor high-voltage switch cabinet applicable to the plateau area provided by the present invention has the following beneficial effects:

[0053] Cooperated with the first servo motor 14, the water diversion plate 12, the first screw rod 5, the first guide rod 9, the lifting support frame 15, the first water pump 2, the first pipeline 3 and the first water suction pipe 4, since the high-voltage switchgear generates heat during operation, especially in summer or during high-load operation periods, when the lifting support frame 15 rises and falls, heat can be effectively removed by spraying water, so that the equipment is maintained within a suitable working temperature range, ensuring the stability of its electrical performance and reducing the risk of failures that may be caused by overheating. Secondly, the switchgear is outdoors, and dust, dirt and other impurities are likely to accumulate on its surface. Spraying water can regularly wash the switchgear to keep the surface of the equipment clean and prevent dust and other pollutants from affecting the heat dissipation and insulation performance of the equipment; Cooperated with the cleaning rubber roller 17, the first rotating rod 19, the second rotating rod 20, the roller 21, the first gear 22, the third gear 51 and the guide groove 23, the cleaning rubber roller 17 can closely fit the outer wall of the high-voltage switchgear during the lifting process. For some stubborn stains or dirt that adheres firmly, through the wiping and squeezing of the cleaning rubber roller 17, it can cooperate with the first pipeline 3 to more effectively remove them. The two steps of spraying and cleaning and wiping and cleaning are completed simultaneously during one lifting process without the need to be carried out separately, thus reducing the time and workload of the cleaning equipment and making the cleaning work more efficient.

[0054] Second Embodiment:

[0055] Based on the outdoor high-voltage switchgear applicable to plateau areas provided in the first embodiment of the present application, the second embodiment of the present application proposes another outdoor high-voltage switchgear applicable to plateau areas. The second embodiment is merely a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0056] The following further describes the second embodiment of the present invention in conjunction with the drawings and the embodiments.

[0057] Please refer to Figures 6 - 17, the outdoor high-voltage switchgear applicable to plateau areas further includes two waterproof grooves integrally formed on the tops of the two water collecting grooves 7. Two movable frames 27 are hinged on each of the water collecting grooves 7. A second filter screen 24 is slidably installed in the movable frame 27. A support plate 29 is fixedly installed in the movable frame 27. A pressure sensor 31 and a spring 30 are fixedly installed on the top of the support plate 29. When dust and impurities accumulate on the two second filter screens 24 to a certain amount and cause the two second filter screens 24 to descend, the two pressure sensors 31 come into contact. The pressure sensor 31 transmits a trigger signal to the corresponding control device, and the control device then drives the second servo motor 35 to operate. At this time, one end of the movable frame 27 is lifted upward by the second screw rod 36, and then the movable frame 27 is in an inclined state to pour out the dust and impurities above, realizing the self-cleaning function. The other end of the spring 30 contacts the second filter screen 24. Two sliding grooves 46 are provided in the movable frame 27. A rack 45 and a third guide rod 44 are respectively provided in the two sliding grooves 46. The rack 45 and the third guide rod 44 are fixedly installed with the same connecting plate 33 at the ends close to the switchgear body 10. Two second screw rods 36 are rotatably installed on the top of the water collecting groove 7. The outer sides of the two second screw rods 36 are threadedly connected with the same lifting plate 34. The connecting plate 33 and the lifting plate 34 are hinged. Two second servo motors 35 are fixedly installed in the waterproof groove. The top end of the second screw rod 36 is fixedly connected with the output shaft of the second servo motor 35. Dust-proof covers 37 are fixedly installed on the tops of the movable frames 27. A connecting rod 41 is rotatably installed in the dust-proof cover 37. A second gear 43 and a first bevel gear 38 are respectively fixedly installed on the outer sides of the two ends of the connecting rod 41. The second gear 43 meshes with the rack 45. A third screw rod 40 is rotatably installed in the dust-proof cover 37. A second bevel gear 39 is fixedly installed at the end of the third screw rod 40 close to the connecting rod 41. The second bevel gear 39 meshes with the first bevel gear 38. One end of a scraping plate 32 is threadedly connected to the outer side of the third screw rod 40. The bottom of the scraping plate �2 contacts the second filter screen 24. When the rack 45 moves in the movable frame 27, the second gear 43 rotates and drives the first bevel gear 38 to rotate through the connecting rod 41. The first bevel gear 38 drives the third screw rod 40 to rotate through meshing with the second bevel gear 39, and the scraping plate 32 starts to move to scrape off the impurities on the second filter screen 24.

[0058] A dust-proof plate 26 is slidably installed in the waterproof groove. The bottom of the dust-proof plate 26 contacts the top of the dust-proof cover 37. When one end of the movable frame 27 close to the switchgear body 10 is lifted upward, the dust-proof plate 26 can be lifted upward through the dust-proof cover 37, thereby preventing water from entering the waterproof groove.

[0059] A second guide rod 42 is fixedly installed inside the dust cover 37. The direction of movement of the scraping plate 32 can be controlled by the second guide rod 42, and the other end of the scraping plate 32 is slidably installed outside the second guide rod 42.

[0060] When rainwater is discharged into the water collecting tank 7 through the two movable frames 27, impurities in the rainwater will be intercepted on the two second filter meshes 24. When a certain amount of impurities accumulates on the two second filter meshes 24, the second filter meshes 24 will descend due to the weight of the accumulated dust and come into contact with the two pressure sensors 31. At this time, the two second servo motors 35 are started. The output shaft of the second servo motor 35 drives the second screw rod 36 to rotate, raising the lifting plate 34, causing the connecting plate 33 to rise with the lifting plate 34 and pulling out the rack 45 and the third guide rod 44. At this time, one end of the second filter mesh 24 close to the switch cabinet body 10 rises, and the dust and impurities are poured out. When the rack 45 moves within the movable frame 27, the second gear 43 rotates, and drives the first bevel gear 38 to rotate through the connecting rod 41. The first bevel gear 38 meshes with the second bevel gear 39, causing the third screw rod 40 to rotate, and the scraping plate 32 starts to move and scrape the impurities on the second filter mesh 24. Through the arrangement of the above components, the present invention can effectively intercept dust and prevent it from entering the water collecting tank 7 in large quantities. When the dust on the second filter mesh 24 reaches a certain weight, it can be automatically tilted and poured out, thus ensuring that the filter mesh can continuously and effectively play a filtering role and avoiding excessive accumulation of dust. Secondly, by automatically pouring out the impurities, the number of times of regular manual cleaning and the required labor cost can be greatly reduced. When the second filter mesh 24 is tilted to pour out dust and impurities, the scraping plate 32 can further remove the dirt remaining on the filter mesh. Since some dust will adhere to the mesh holes or the surface of the filter mesh, the scraping plate 32 can effectively scrape off these stubborn stains, making the filter mesh cleaner and preventing dust from accumulating in the mesh holes of the filter mesh and causing blockage, thereby affecting the collection and flow of rainwater.

[0061] Third Embodiment:

[0062] Based on the outdoor high-voltage switch cabinet applicable to plateau areas provided in the second embodiment of the present application, the third embodiment of the present application proposes another two outdoor high-voltage switch cabinets applicable to plateau areas. The third embodiment is merely a preferred manner of the third embodiment, and the implementation of the third embodiment will not affect the separate implementation of the third embodiment.

[0063] The following further describes the third embodiment of the present invention in conjunction with the drawings and the embodiments.

Two filter boxes 47 are fixedly installed in the switchgear body 10. Two activated carbon fiber meshes 11 and a second pipe 8 are fixedly installed in the filter box 47. A plurality of atomizing nozzles are provided at the bottom of the second pipe 8. The atomizing nozzles can form a water curtain by continuously spraying water, taking away part of the heat of the air, which helps to reduce the air temperature around the switchgear. Moreover, it can also maintain the temperature and humidity inside the switchgear body 10. Keeping the air moist can reduce the risk of fire around the switchgear. The activated carbon fiber mesh 11 can effectively adsorb harmful gases and impurity dust in the air, and the water mist sprayed by the atomizing nozzles can wash the dust and impurities adsorbed on the activated carbon fiber mesh 11, preventing the filter screen from being blocked by dust and other impurities. A second water pump 48 is fixedly installed on one side of each of the two filter boxes 47. The water inlet end of the second water pump 48 is fixedly installed with a second water suction pipe 49. The other end of the second water suction pipe 49 extends into the water collecting tank 7. One ends of the two second pipes 8 are respectively fixedly installed on the water outlet ends of the two second water pumps 48. A plurality of second water diversion holes 28 and first water diversion holes 25 are provided on the switchgear body 10.

A communication port is provided on the side of the filter box 47 away from the second pipe 8. A second dust-proof net 50 is fixedly installed in the communication port.

[0065] A plurality of drain holes 18 are provided on the filter box 47. The drain holes 18 are communicated with the second water diversion holes 28.

[0066] A plurality of the drain holes 18 are all located between the two activated carbon fiber meshes 11. When too much water adheres to the two activated carbon fiber meshes 11, the excess water can be discharged through the drain holes 18.

[0067] When it is necessary to reduce the temperature inside the switchgear body 10, first turn on the second water pump 48. The second water pump 48 pumps the water in the water collecting tank 7 through the second water suction pipe 49, and then conveys it into the second pipe 8. The atomizing nozzles at the top of the second pipe 8 spray the water onto the activated carbon fiber mesh 11 near the second pipe 8, making the activated carbon fiber mesh 11 near the second pipe 8 damp. Then start the fan 16. The fan 16 extracts the air outside the switchgear body 10. When the air enters the filter box 47, the two activated carbon fiber meshes 11 adsorb the dust, and the filtered air enters the switchgear body 10 through the second dust-proof net 50. In this way, not only can the dust in the air be filtered, but also the temperature of the air can be reduced. Subsequently, the water is discharged into the first water guiding hole 25 through the drain hole 18 and the second water guiding hole 28, and finally enters the water collecting tank 7 again. Through the arrangement of the above components, the present invention can effectively adsorb harmful gases and impurity dust in the air. The water mist sprayed by the second pipe 8 can wash the dust and impurities adsorbed on the activated carbon fiber mesh 11, keeping the filter screen in good adsorption performance and preventing the filter screen from being blocked by dust and other impurities, which affects its adsorption efficiency. Secondly, by continuously spraying water, part of the heat can be taken away, which helps to reduce the air temperature around the switchgear, and can also maintain the temperature and humidity inside the switchgear body 10. Keeping the air moist can reduce the risk of fire around the switchgear.

[0068] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
