Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and particularly to an automatic dust removal component for a box-type substation. Background Art

[0002] A box-type substation is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device, which are factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. Although the box-type substation usually adopts a fully enclosed design, to solve the problem of heat dissipation of its internal power transformation equipment, air inlets and air outlets are usually provided on the side walls of the box to perform ventilation and heat dissipation, and a filter screen is provided at the air inlet to reduce the entry of dust, thereby playing a role in dust removal and dust prevention for its internal power transformation equipment.

[0003] The patent with publication number CN219745604U discloses an automatic dust removal device for a substation terminal box. Through the setting of a dust removal component, it can achieve regular automatic dust removal, saving a certain amount of manpower while improving the efficiency of cleaning and dust removal. This application removes dust from power transformation equipment by scraping. Although it can achieve a certain dust removal effect, during the scraping process, dust will be squeezed, causing the dust to enter the power transformation equipment through the ventilation opening, reducing the dust removal effect.

[0004] The patent with publication number CN109621581B discloses a roll-net type easy-to-clean dust removal device. By rotating a roll-net roller, the dust-covered filter net is rolled downwards. At the same time, as the roll-net roller winds up the filter net, the dust-sweeping block sweeps the dust adhered to the filter net to achieve cleaning. This application winds up and unfolds a flexible filter net and cleans the flexible filter net during this process to improve the dust removal effect.

[0005] Based on the existing technologies, the following problems exist:

[0006] The above application documents only remove dust by scraping, or when cleaning the dust adhered to the surface of the flexible filter net, although it can be automatically cleaned without manual cleaning, during the cleaning process, dust splashes everywhere and is easily adhered to the surface of the flexible filter net again, resulting in a poor effect. Moreover, some box-type substations are installed outdoors, and the problem of rain protection for the box-type substation needs to be considered while removing dust;

[0007] During the process of winding up and unfolding the flexible filter net, the flexible filter net moves, resulting in a gap between the flexible filter net and the ventilation opening of the power transformation equipment, thereby reducing the dust removal effect, and there are certain deficiencies. To solve the above problems, an automatic dust removal component for a box-type substation is proposed. Summary of the Invention

[0008] To overcome the deficiencies of the above-mentioned prior art, the present invention provides an automatic dust removal assembly for a box-type substation, which transfers the filter screen that blocks dust to a position away from the air inlet of the box-type substation and then cleans it, thereby reducing the re-adhesion of dust, improving the cleaning effect, and having the function of rain protection.

[0037] The present invention provides an automatic dust removal assembly for a box-type substation. Compared with the prior art, it has the following beneficial effects:

[0038] 1. In the present invention, the flexible rain cloth and the flexible filter screen are spliced, so as to block the dust in the gas entering the box-type substation through the flexible filter screen, waterproof through the flexible rain cloth, and arrange the flexible filter screen to the outside of the air inlet of the box-type substation through the third roller body and the fourth roller body, and a cleaning assembly is arranged at this position, so that the cleaning assembly cleans the dust adhered to the surface of the flexible filter screen outside the air inlet of the box-type substation, reduces the dust adhered to the surface of the flexible filter screen again, improves the cleaning effect, and there is a certain distance between the folded flexible rain cloth and the flexible filter screen through the third roller body and the fourth roller body, so as to facilitate the gas to enter the box-type substation between the flexible filter screen and the flexible filter screen, without affecting the air intake while preventing rain, and the first sealing assembly and the second sealing assembly cooperate to seal between the flexible filter screen and the air guide plate, avoiding dust from entering the box-type substation between the flexible filter screen and the air guide plate.

[0039] 2. In the present invention, the position of the flexible rain cloth and the flexible filter screen is limited by the adjusting assembly.

[0040] 3. The present invention reduces the dust adhering to the surface of the flexible filter screen again by cleaning the dust adhering to the surface of the flexible filter screen outside the air inlet of the box-type substation with the cleaning component, and makes the two brush barrels clean both sides of the flexible filter screen to improve the cleaning effect. The cleaned dust is blocked in the shell, and the dust adhering to the surface of the flexible filter screen is cleaned in the shell, and then discharged after being filtered, so as to avoid the cleaned dust adhering to the surface of the flexible filter screen again and further improve the cleaning effect.

[0041] 4. The present invention seals between the flexible filter screen and the air guide plate from the top and bottom by moving the flexible filter screen and the sealing strip in the sealing groove, and seals between the flexible filter screen and the air guide plate from both sides by magnetically attracting and fixing the strip-shaped magnet to the magnetic metal strip, so as to prevent dust from entering the box-type substation between the flexible filter screen and the air guide plate, and makes the strip-shaped magnet and the magnetic metal strip fit stably by bending the flexible rain cloth inward through the fourth roller body.

[0069] A second roller 212, with a flexible rain cloth 214 wound around the side wall of the second roller 212, and one side of the flexible rain cloth 214 is fixedly connected to the side wall of the second roller 212. The other side of the flexible rain cloth 214 is fixedly connected to the side of the flexible filter screen 215 away from the first roller 213. On the side of the flexible filter screen 215 and the flexible rain cloth 214 close to each other and away from the first roller 213, a third roller 217 and a fourth roller 216 are provided to guide the arrangement of the flexible rain cloth 214 and the flexible filter screen 215, so that the flexible rain cloth 214 and the flexible filter screen 215 are folded and arranged and extend to the outside of the air inlet of the box-type substation 1. A cleaning component 24 for cleaning dust is provided between the third roller 217 and the fourth roller 216;

[0070] The first roller 213 and the second roller 212 are linked, so that when the second roller 212 winds up the flexible rain cloth 214, the first roller 213 unfolds the flexible filter screen 215, or when the second roller 212 unfolds the flexible rain cloth 214, the first roller 213 winds up the flexible filter screen 215;

[0071] A second servo motor 211 is fixedly provided on the side wall of the second mounting plate 231, and the output shaft of the second servo motor 211 is fixedly connected to the second roller 212 through a coupling. Both the first roller 213 and the second roller 212 are rotatably connected to the second mounting plate 231.

[0072] The third roller body 217 is located on the side of the fourth roller body 216 away from the air guide plate 233, and the fourth roller body 216 is located inside the convex part of the air guide plate 233, so that when the fourth roller body 216 guides the flexible filter screen 215, the flexible filter screen 215 is bent inward. The flexible filter screen 215 and the flexible rain cloth 214 are arranged on the outer sides of the third roller body 217 and the fourth roller body 216, and both the third roller body 217 and the fourth roller body 216 are rotatably connected to the outer wall of the housing 241.

[0073] In specific implementation, the flexible rain cloth 214 and the flexible filter screen 215 are spliced to block the dust in the gas entering the box-type substation 1 through the flexible filter screen 215, waterproof through the flexible rain cloth 214, and arrange the flexible filter screen 215 to the outside of the air inlet of the box-type substation 1 through the third roller body 217 and the fourth roller body 216, and a cleaning component 24 is arranged at this position, so that the cleaning component 24 cleans the dust adhered to the surface of the flexible filter screen 215 outside the air inlet of the box-type substation 1, reduces the dust adhering to the surface of the flexible filter screen 215 again, improves the cleaning effect, and there is a certain distance between the folded flexible rain cloth 214 and the flexible filter screen 215 through the third roller body 217 and the fourth roller body 216, so that the gas can enter the box-type substation 1 between the flexible filter screen 215 and the flexible filter screen 215, preventing rain without affecting air intake.

[0074] By adjusting the positions of the flexible rain cloth 214 and the flexible filter screen 215, dust removal and rain prevention are carried out on the air inlet of the box-type substation 1. When the flexible rain cloth 214 is completely wound around the side wall of the first roller body 213 or the flexible rain cloth 214 is far away from the air inlet of the box-type substation 1, a folded flexible filter screen 215 is formed outside the air inlet of the box-type substation 1. At this time, the flexible filter screen 215 can reduce the dust entering the box-type substation 1 along the air inlet of the box-type substation 1, playing the role of dust removal and dust prevention.

[0075] When the flexible rain cloth 214 is unfolded, the flexible rain cloth 214 and the flexible filter screen 215 are arranged in a folded manner. At this time, the gas enters the box-type substation 1 between the flexible rain cloth 214 and the flexible filter screen 215. While ensuring normal ventilation, the flexible rain cloth 214 and the baffle 22 cooperate to block the rainwater, playing the role of waterproof while removing dust.

[0076] When specifically adjusting the flexible rain cloth 214 and the flexible filter screen 215, start the second servo motor 211. The output shaft of the second servo motor 211 drives the first roller 213 and the second roller 212 to rotate synchronously. By setting the winding direction of the flexible rain cloth 214 on the side wall of the second roller 212 and the winding direction of the flexible filter screen 215 on the side wall of the first roller 213, when the flexible rain cloth 214 is unfolded, the flexible filter screen 215 is wound up, or when the flexible rain cloth 214 is wound up, the flexible filter screen 215 is unfolded, so as to facilitate synchronous adjustment and use;

[0077] Fixed sleeves are provided at the tops of the side walls of the first roller 213 and the second roller 212, and the gears are connected by a chain drive, so that the first roller 213 and the second roller 212 are linked.

[0078] Please refer to Figure 3 、 Figure 4 and Figure 5 , the cleaning assembly 24 includes:

[0079] A housing 241 is fixedly provided on the outside of the first mounting plate 234 and is located between the third roller 217 and the fourth roller 216. A through groove is provided on the side wall of the housing 241, so that the housing 241 is sleeved on the outside of the flexible filter screen 215 through the through groove, thereby blocking the dust to be cleaned inside the housing 241. Brush barrels 248 are rotatably provided on both sides of the flexible filter screen 215 on the inner wall of the housing 241, and the tops of the brush barrels 248 extend to the top of the housing 241. The two brush barrels 248 are linked;

[0080] A first servo motor 247 is fixedly provided on the outside of the first mounting plate 234. The output shaft of the first servo motor 247 is fixedly connected to one of the brush barrels 248 through a coupling to drive the brush barrel 248 to rotate, thereby cleaning the flexible filter screen 215.

[0081] The cleaning assembly 24 further includes:

[0082] A pump body 245 is fixedly provided on the side wall of the first mounting plate 234. The air inlet end of the pump body 245 is fixedly provided with a first conduit 246 extending into the housing 241, and the air outlet end of the pump body 245 is fixedly provided with a second conduit 244;

[0083] A water storage tank 243 is fixedly provided on the outside of the box-type substation 1. The exhaust end of the second conduit 244 extends into the water storage tank 243 and is located below the liquid level of the water in the water storage tank 243. A third conduit 242 extending into the water storage tank 243 is fixedly provided on the side wall of the water storage tank 243 and is located above the liquid level of the water in the water storage tank 243. Both the first conduit 246 and the second conduit 244 are designed as hoses, and the second conduit 244 has a length reserved for moving with the first mounting plate 234.

[0084] In specific implementation, the first servo motor 247 is started, and the first servo motor 247 drives the two brush barrels 248 to rotate synchronously, so as to clean both sides of the flexible filter screen 215, improve the cleaning effect, and the dust generated during cleaning is blocked inside the housing 241. Then, the pump body 245 is started. The pump body 245 sucks the gas and dust inside the housing 241 into the pump body 245 through the first conduit 246, and discharges them into the water storage tank 243 along the exhaust end of the pump body 245 and the second conduit 244. The dust in the gas is filtered by the water in the water storage tank 243, and the filtered gas is discharged through the third conduit 242. By cleaning the dust adhering to the surface of the flexible filter screen 215 inside the housing 241 and then filtering and discharging the dust, it is avoided that the cleaned dust adheres to the surface of the flexible filter screen 215 again, thus improving the cleaning effect;

[0085] At one end of the side wall at the top of the housing 241 where the brush barrels 248 are located, gears are fixedly sleeved, and the gears are connected by a chain drive to link the two brush barrels 248 together.

[0086] Please refer to Figure 6 、 Figure 7 and Figure 8 As shown in, the adjusting assembly 25 includes:

[0087] The fifth roller body 253 is movably arranged outside the flexible rain cloth 214 to limit the flexible rain cloth 214 and the flexible filter screen 215, so that the folded flexible filter screen 215 and the flexible rain cloth 214 approach or move away from each other.

[0088] The adjusting assembly 25 further includes:

[0089] The bracket 251 is fixedly arranged on the front surfaces of the first mounting plate 234 and the second mounting plate 231. A connecting plate 256 is fixedly arranged on the back surface of the bracket 251, and a first electromagnet 254 is fixedly arranged on the back surface of the connecting plate 256;

[0090] The connecting frame 255 is rotatably arranged at both ends of the side wall of the fifth roller body 253. A second electromagnet 252 is fixedly arranged on the front surface of the connecting frame 255, and the sides of the second electromagnet 252 and the first electromagnet 254 that are close to each other are of the same pole.

[0091] In specific implementation, the position of the flexible rain cloth 214 and the flexible filter screen 215 is limited by the fifth roller body 253. When limiting the flexible filter screen 215, the fifth roller body 253 squeezes the flexible filter screen 215, making the folded flexible filter screens 215 approach and press against each other, thereby improving the dust prevention effect. And by adjusting the position of the folded flexible filter screens 215, the position of the filter holes of the flexible filter screen 215 is adjusted, which not only blocks dust but also facilitates the adjustment of the air intake volume. When limiting the flexible rain cloth 214, the flexible rain cloth 214 is made to approach the flexible filter screen 215, thereby reducing the distance between the flexible rain cloth 214 and the flexible filter screen 215, and preventing rainwater from entering the box-type substation 1 along the flexible filter screen 215 when the rain is too heavy. It can be adjusted according to the actual situation to improve the actual use effect;

[0092] In specific adjustment, the repulsion force generated between the first electromagnet 254 and the second electromagnet 252 drives the second electromagnet 252, the connecting frame 255 and the fifth roller body 253 to move, thereby adjusting the limiting position of the fifth roller body 253 on the flexible rain cloth 214 and the flexible filter screen 215.

[0093] The bracket 251 is designed in a U shape, and the inner side of the bracket 251 is located outside the flexible rain cloth 214 and the flexible filter screen 215, so as not to affect the winding of the flexible rain cloth 214 and the flexible filter screen 215;

[0094] On the back of the connecting frame 255 and at the top and bottom of the second electromagnet 252, second guide rods are fixedly provided. Second guide holes adapted to the second guide rods are opened on the side wall of the connecting plate 256, and the second guide rods are sleeved in the second guide holes to limit the movement of the connecting frame 255 and the fifth roller body 253, so as to ensure the stability of the movement of the fifth roller body 253;

[0095] On the side wall of the box-type substation 1 and at the top of the air guide plate 233, a baffle 22 is fixedly provided, and the side of the baffle 22 away from the box-type substation 1 is located outside the flexible rain cloth 214. The baffle 22 blocks the top position between the flexible rain cloth 214 and the flexible filter screen 215 to ensure the rainproof effect.

[0096] Embodiment Two: Please refer to Figure 10 and Figure 12 , the different technical solutions of this embodiment compared with Embodiment One are that the first sealing assembly 27 includes:

[0097] Sealing seats 271 are fixedly provided at the upper front end and the lower front end of the air guide plate 233. Sealing grooves 272 are opened on the sides of the sealing seats 271 close to each other, and the sealing grooves 272 are designed in a T shape;

[0098] The sealing strip 273 is fixedly arranged at the upper front end and the upper back end of the flexible filter screen 215, and is symmetrically designed with the center point of the flexible filter screen 215. Both the sealing strip 273 and the flexible filter screen 215 are sleeved in the sealing groove 272.

[0099] In specific implementation, the flexible filter screen 215 and the sealing strip 273 move in the sealing groove 272, so as to seal between the flexible filter screen 215 and the air guide plate 233 from the top and bottom through the sealing groove 272, the sealing seat 271 and the sealing strip 273, and prevent dust from entering the box-type substation 1 between the flexible filter screen 215 and the air guide plate 233.

[0100] Please refer to Figure 11 and Figure 13 , the second sealing assembly 26 includes:

[0101] The mounting seat 264 is fixedly arranged on both sides of the front of the air guide plate 233 and is perpendicular to the sealing seat 271. The top and bottom of the mounting seat 264 are attached to the inner side of the sealing seat 271. A strip magnet 265 is fixedly arranged on the front of the mounting seat 264;

[0102] The first clamping plate 263 is arranged on the front of the flexible filter screen 215, and the second clamping plate 262 is arranged on the back of the flexible filter screen 215. The first clamping plate 263 and the second clamping plate 262 are designed in parallel to arrange the flexible filter screen 215 between the first clamping plate 263 and the second clamping plate 262, and the first clamping plate 263 and the second clamping plate 262 are fixedly connected. A magnetic metal strip 261 is fixedly arranged on the side of the second clamping plate 262 away from the first clamping plate 263, so that the strip magnet 265 magnetically attracts and fixes the magnetic metal strip 261. The first clamping plate 263, the second clamping plate 262 and the magnetic metal strip 261 are all arranged at intervals, and the interval distance corresponds to the position of the strip magnet 265.

[0103] In specific implementation, by making the strip magnet 265 magnetically attract and fix the magnetic metal strip 261, the sealing between the flexible filter screen 215 and the air guide plate 233 is further improved from both sides, and the flexible rain cloth 214 is bent inward by the fourth roller 216, so as to improve the stability of the fitting between the strip magnet 265 and the magnetic metal strip 261.

[0104] Please refer to Figure 14 , the dust removal mechanism 2 further includes a mounting assembly 23, and the mounting assembly 23 includes:

[0105] The air guide plate 233 is fixedly arranged at the air inlet of the box-type substation 1 through bolts. The first mounting plate 234 and the second mounting plate 231 are movably arranged on both sides of the air guide plate 233 respectively. And the side of the air guide plate 233 away from the box-type substation 1 is designed to protrude outward relative to the first mounting plate 234 and the second mounting plate 231. A threaded rod 232 is rotatably arranged inside the air guide plate 233. One end of the threaded rod 232 extends into the first mounting plate 234 and is threadedly connected with the first mounting plate 234. The other end of the threaded rod 232 penetrates through the second mounting plate 231 and extends outside the second mounting plate 231 and is threadedly connected with the second mounting plate 231. The thread directions at both ends of the side wall of the threaded rod 232 are opposite, so that the first mounting plate 234 and the second mounting plate 231 approach or move away from each other. On the side where the first mounting plate 234 and the second mounting plate 231 approach each other and at the top and bottom of the threaded rod 232, first guide rods are fixedly arranged. First guide holes adapted to the first guide rods are formed on both sides of the air guide plate 233. The first guide rods are sleeved in the first guide holes to limit the movement of the first mounting plate 234 and the second mounting plate 231. A first sealing assembly 27 and a second sealing assembly 26 for sealing between the air guide plate 233 and the flexible filter screen 215 are arranged on the front surface of the air guide plate 233.

[0106] During specific implementation, when installing the dust removal mechanism 2 in front of the air inlet of the box-type substation 1, rotate the threaded rod 232. Since the thread directions at both ends of the side wall of the threaded rod 232 are opposite, it is convenient to drive the first mounting plate 234 and the second mounting plate 231 to approach or move away from each other, so as to adjust the arrangement of the flexible rain cloth 214 and the flexible filter screen 215 without affecting the installation shell 241, etc. At the same time, it is necessary to adjust the unfolding lengths of the flexible filter screen 215 and the flexible rain cloth 214 to avoid affecting the adjustment of the installation assembly 23. And the flexible filter screen 215 and the flexible rain cloth 214 usually have a certain elasticity for actual use.

[0107] The electronic devices such as the first servo motor 247 of the present invention are all connected to an external power supply and a controller through wires for actual control and use. The above are all prior arts and will not be elaborated here.

[0108] When the present invention is implemented, the flexible rain cloth 214 and the flexible filter screen 215 are spliced, so as to block the dust in the gas entering the box-type substation 1 through the flexible filter screen 215, waterproof through the flexible rain cloth 214, and arrange the flexible filter screen 215 outside the air inlet of the box-type substation 1 through the third roller 217 and the fourth roller 216, and a cleaning component 24 is arranged at this position, so that the cleaning component 24 cleans the dust adhered to the surface of the flexible filter screen 215 outside the air inlet of the box-type substation 1, reduces the dust adhered to the surface of the flexible filter screen 215 again, improves the cleaning effect, and there is a certain distance between the folded flexible rain cloth 214 and the flexible filter screen 215 through the third roller 217 and the fourth roller 216, so as to facilitate the gas to enter the box-type substation 1 between the flexible filter screen 215 and the flexible filter screen 215, preventing rain without affecting air intake. When the flexible rain cloth 214 is completely wound onto the side wall of the first roller 213, or when the flexible rain cloth 214 is far away from the air inlet of the box-type substation 1, a folded flexible filter screen 215 is formed outside the air inlet of the box-type substation 1 as Figure 15 shown. At this time, the flexible filter screen 215 can reduce the dust entering the box-type substation 1 along the air inlet of the box-type substation 1, playing the role of dust removal and dust prevention. When the flexible rain cloth 214 is unfolded, the flexible rain cloth 214 and the flexible filter screen 215 are arranged in a folded manner as Figure 16 . At this time, the gas enters the box-type substation 1 between the flexible rain cloth 214 and the flexible filter screen 215. While ensuring normal ventilation, the flexible rain cloth 214 and the baffle 22 cooperate to block the rainwater, playing the role of waterproof while removing dust;

[0109] During the process of adjusting the flexible filter screen 215, the first sealing component 27 and the second sealing component 26 seal between the flexible filter screen 215 and the air guide plate 233, preventing dust from entering the box-type substation 1 between the air guide plate 233 and the flexible filter screen 215, improving the dust removal effect, and adjusting the positions of the folded flexible rain cloth 214 and the flexible filter screen 215 located outside through the adjusting component 25 to assist in dust removal and rain prevention, improving the dust removal and rain prevention effects.
