Description

Technical Field

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

[0002] A box-type substation is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. Although box-type substations usually adopt a fully enclosed design, in order to meet the heat dissipation problem of its internal substation equipment, air inlets and exhaust ports are usually set on the side walls of the box for ventilation and heat dissipation, and filters are set at the air inlets to reduce dust entry, thereby playing a role in dust removal and dust prevention for its internal substation equipment.

[0003] Publication number CN219745604U discloses an automatic dust removal device for a substation terminal box, which can realize regular automatic dust removal through the setting of dust removal components, saving a certain amount of manpower while improving the efficiency of cleaning and dust removal. This application removes dust from the substation equipment by scraping, which can achieve a certain dust removal effect. However, during the scraping process, dust will be squeezed, so that the dust enters the substation equipment through the vents, reducing the dust removal effect.

[0004] Publication number CN109621581B discloses a roll-up dust removal device that is easy to clean. The device rolls up the dust-covered filter screen by rotating the roll-up roller. At the same time, as the roll-up roller rolls up the filter screen, the dust sweeping block sweeps off the dust adhered to the filter screen to achieve cleaning. This application improves the dust removal effect by rolling up and unfolding the flexible filter screen and cleaning the flexible filter screen in the process.

[0005] Based on the existing technology, there are the following problems: The above application documents only remove dust by scraping, or when cleaning the dust adhering to the surface of the flexible filter, although no manual cleaning is required and automatic cleaning can be achieved, the dust splashes during cleaning and is easy to adhere to the surface of the flexible filter again, resulting in poor effect. In addition, some box-type substations are installed outdoors, and the problem of rain protection of the box-type substations needs to be considered while removing dust; In the process of rolling and unfolding the flexible filter, the flexible filter moves, resulting in a gap between the flexible filter and the ventilation port of the substation equipment, thereby reducing the dust removal effect. There are certain shortcomings. In order to solve the above problems, an automatic dust removal component for a box-type substation is proposed. Summary of the invention

[0037] In a specific implementation, the strip magnet 265 is used to magnetically fix the magnetic metal strip 261, thereby sealing the flexible filter 215 and the air guide plate 233 from both sides to further improve the sealing effect, and the flexible rain cloth 214 is bent inward by the fourth roller 216, thereby ensuring the stability of the fit between the strip magnet 265 and the magnetic metal strip 261.

[0038] See also Fig.14 The dust removal mechanism 2 also includes a mounting assembly 23, and the mounting assembly 23 includes: The air guide plate 233 is fixed at the air inlet of the box-type substation 1 by bolts. The first mounting plate 234 and the second mounting plate 231 are movably arranged on both sides of the air guide plate 233, 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. The air guide plate 233 is internally rotatably provided with a threaded rod 232, one end of the threaded rod 232 extends into the first mounting plate 234 and is threadedly connected to the first mounting plate 234, and the other end of the threaded rod 232 passes through the second mounting plate 231 and extends to the outside of the second mounting plate 231, and is threadedly connected to the second mounting plate 231. The threads at both ends of the side wall of the threaded rod 232 are in opposite directions so that the first mounting plate 234 and the second mounting plate 231 are close to or away from each other. A first guide rod is fixedly provided on the side where the first mounting plate 234 and the second mounting plate 231 are close to each other and at the top and bottom of the threaded rod 232.

[0039] In a specific implementation, when the dust removal mechanism 2 is installed in front of the air inlet of the box-type substation 1, the threaded rod 232 is rotated. 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 move closer to or away from each other, so as to adjust the arrangement of the flexible tarpaulin 214 and the flexible filter screen 215 without affecting the installation shell 241, etc. At the same time, it is necessary to adjust the unfolded length of the flexible filter screen 215 and the flexible tarpaulin 214 to avoid affecting the adjustment of the installation component 23, and the flexible filter screen 215 and the flexible tarpaulin 214 usually have a certain elasticity to facilitate practical use.

[0040] The first servo motor 247 and other electronic components of the present invention are connected to an external power supply and a controller through wires for practical control and use. The above are all prior arts and will not be elaborated here.

[0041] When the present invention is implemented, 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, and the flexible rain cloth 214 is used for waterproofing, and the flexible filter screen 215 is arranged 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 set at this position, so that the cleaning component 24 cleans the dust adhering to the surface of the flexible filter screen 215 on the outside of the air inlet of the box-type substation 1, thereby reducing the dust adhering to the flexible filter screen again. The dust on the surface of 215 is improved, and the cleaning effect is improved, and the third roller body 217 and the fourth roller body 216 make a certain distance between the folded flexible rain cloth 214 and the flexible filter screen 215, so that the gas can enter the box-type substation 1 from between the flexible filter screens 215 and the flexible filter screens 215, and the rainproof does not affect the air intake. When the flexible rain cloth 214 is completely rolled up to the side wall of the first roller body 213, or the flexible rain cloth 214 is away from the air inlet of the box-type substation 1, the outer side of the air inlet of the box-type substation 1 forms a folded flexible filter screen 215. Fig.15 As shown, at this time, the flexible filter 215 can reduce the dust from entering the box-type substation 1 along the air inlet of the box-type substation 1, which plays a role in dust removal and dust prevention. When the flexible rain cloth 214 is unfolded, the flexible rain cloth 214 and the flexible filter 215 are folded and arranged as shown in FIG. Fig.16 At this time, the gas enters the box-type substation 1 from between the flexible rain cloth 214 and the flexible filter screen 215, ensuring normal ventilation while the flexible rain cloth 214 and the baffle 22 can block rainwater, remove dust and play a waterproof role; During the process of adjusting the flexible filter 215, the first sealing component 27 and the second sealing component 26 are used to seal the flexible filter 215 and the air guide plate 233 to prevent dust from entering the box-type substation 1 from between the air guide plate 233 and the flexible filter 215, thereby improving the dust removal effect. The positions of the flexible tarpaulin 214 and the flexible filter 215, which are folded in half and located on the outside, are adjusted by the adjustment component 25 to assist in dust removal and rain protection, thereby improving the dust removal and rain protection effects.
