Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, specifically a dust removal mechanism for substation operation and maintenance. Background Technology

[0002] The normal operation of a substation requires the simultaneous operation of multiple electrical devices. Dust accumulation on the surface of these devices can lead to a decrease in insulation performance and increase the risk of short circuits. Therefore, it is necessary to clean the dust to facilitate the maintenance of the electrical equipment.

[0003] In the prior art, the main dust removal methods include brushes, vacuum cleaners, or a combination of both. Brushes can effectively remove dust from the surface of electrical equipment; however, this method may cause dust to float in the air during operation. Although vacuum cleaners can effectively pick up some dust, their size limits their coverage area on the surface of electrical equipment, thus they cannot fully extract dust from the air. This causes dust to float in the air for a long time, which not only affects the health of workers but also increases the potential risk of short circuits in the equipment. Therefore, this application provides a dust removal mechanism for substation operation and maintenance. Utility Model Content

[0004] To address the shortcomings of the existing technology, the present invention aims to provide a dust removal mechanism for substation operation and maintenance. This mechanism uses a deformable sponge pad to cover the surface of electrical equipment in the substation, allowing dust to be adsorbed into the pores within the sponge pad, preventing dust from floating in the air, and increasing dust removal efficiency and operational safety.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A dust removal mechanism for substation operation and maintenance is provided, including a dust removal body, a sponge pad, and a dust collection body. A plate is slidably installed inside the dust removal body, and a sponge pad is fixedly installed at the bottom of the plate. The dust collection body can be connected to the dust removal body to accommodate the sponge pad. Multiple air inlet pipes and exhaust pipes are fixedly connected and connected at both ends of the dust collection body. A filter cartridge is installed on the exhaust pipe, and the other end of the air inlet pipe is connected to the air supply equipment through a pipe.

[0007] Furthermore, the air supply equipment may use an air pump or a booster fan.

[0008] Furthermore, a first linear electric cylinder is installed inside the dust removal body. A connecting rod is rotatably mounted on the movable end of the first linear electric cylinder, and the other end of the connecting rod is rotatably connected to a hinge seat on the top of the plate.

[0009] Furthermore, the outer side of the sponge pad has an outwardly protruding arc surface in the middle.

[0010] Furthermore, the sponge pad is equipped with a plurality of through columns that penetrate the sponge pad, and the dust removal body and the ash collection body are respectively provided with a first limiting groove and a second limiting groove for accommodating and limiting the through columns.

[0011] Furthermore, a slide rail is provided at the bottom of the ash collection body, and a slider is slidably installed on the slide rail. The slider is installed at the bottom of the ash scraper, and the top of the ash scraper abuts against the outer side of the sponge pad. A second linear electric cylinder for driving the slider to move is installed inside the ash collection body.

[0012] Furthermore, a handle is rotatably mounted on the dust removal body, and a damping sleeve is mounted on the outer side of the rotating shaft at the end of the handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The dust removal mechanism for substation operation and maintenance of this utility model involves bringing the outer side of a sponge pad into contact with the surface of electrical equipment in the substation and moving it back and forth in a small amplitude. This allows dust to detach from the surface of the electrical equipment and enter the pores inside the sponge pad, preventing dust from floating in the air and increasing the dust removal effect and operational safety.

[0015] 2. In the dust removal mechanism for substation operation and maintenance of this utility model, the sponge pad can retract into the dust removal body, so that the sponge pad will not come into contact with the area before the equipment is moved to the designated area that needs to be cleaned, thus avoiding dust flying due to accidental scratches.

[0016] 3. The dust removal mechanism for substation operation and maintenance of this utility model, after the dust removal body and the ash collection body are connected, the control board moves back and forth vertically within the dust removal body to vibrate the sponge pad. Combined with the airflow generated by the air supply equipment, the surface of the sponge pad is blown, so that the dust in the air pores of the sponge pad enters the ash collection body and is finally collected in the filter cartridge, so that the sponge pad can perform the next cycle of dust removal operation on the electrical equipment of the substation, thereby improving the operation efficiency.

[0017] 4. In the dust removal mechanism for substation operation and maintenance of this utility model, the top of the dust scraper abuts against the outer side of the sponge pad and scrapes the outer side of the sponge pad so that dust can be removed from the surface of the sponge pad.

[0018] 5. The dust removal mechanism for substation operation and maintenance of this utility model has a sponge pad that can deform freely. Compared with traditional brushes, it can adapt to various product surfaces and has a better performance. Attached Figure Description

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Furthermore, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0032] Example 1:

[0033] like Figure 1-3 As shown, this embodiment provides a dust removal mechanism for substation operation and maintenance, including a dust removal body 11, a sponge pad 14 and a dust collection body 31. A plate 13 is slidably installed inside the dust removal body 11, and a sponge pad 14 is fixedly installed at the bottom of the plate 13. The sponge pad 14 can be freely deformed and can adapt to various product surfaces compared to traditional brushes.

[0034] A handle 12 is rotatably mounted on the dust removal body 11. A damping sleeve is installed on the outer side of the rotating shaft at the end of the handle 12. The damping sleeve is used to limit the relative angular position between the handle 12 and the dust removal body 11, so that the device can be inserted into a narrow gap for dust removal.

[0035] The two ends of the ash collection body 31 are respectively fixedly connected and connected to multiple air inlet pipes 32 and exhaust pipes 33. The exhaust pipe 33 is equipped with a filter cartridge 34. The other end of the air inlet pipe 32 is connected to the air supply equipment through a pipe. The air supply equipment can be an air pump or a booster pipe fan.

[0036] like Figure 1As shown, the dust collection body 31 can be connected to the dust removal body 11 to accommodate the sponge pad 14. The control board 13 moves vertically back and forth within the dust removal body 11 to vibrate the sponge pad 14. Combined with the airflow generated by the air supply equipment, the surface of the sponge pad 14 is blown, causing the dust in the pores of the sponge pad 14 to enter the dust collection body 31 and finally be collected in the filter cartridge 34. This allows the sponge pad 14 to perform the next cycle of dust removal operation on the electrical equipment of the substation, improving the operation efficiency.

[0037] like Figure 3 As shown, a first linear electric cylinder 22 is installed inside the dust removal body 11. A connecting rod 23 is rotatably installed on the movable end of the first linear electric cylinder 22. The other end of the connecting rod 23 is rotatably connected to the hinge seat 21 on the top of the plate 13. When the first linear electric cylinder 22 is started, the plate 13 is driven to reciprocate vertically within the dust removal body 11.

[0038] The specific method for using the dust removal mechanism for substation operation and maintenance of this application to remove dust from electrical equipment in a substation is as follows: Hold the handle 12 and move the dust removal body 11 to the designated area to be cleaned. Start the first linear electric cylinder 22 to control the sponge pad 14 to extend outward inside the dust removal body 11, so that the outer side of the sponge pad 14 can come into contact with the surface of the electrical equipment. Move the dust removal body 11 back and forth in a small range so that the dust is removed from the surface of the electrical equipment and enters the air pores inside the sponge pad 14, preventing the dust from floating in the air and increasing the dust removal effect and operational safety.

[0039] Because the sponge pad 14 can retract into the dust removal body 11, the sponge pad 14 will not come into contact with the area before the equipment moves to the designated area that needs to be cleaned, thus avoiding dust flying due to accidental scratches.

[0040] To improve the dust removal effect of the equipment on electrical equipment, such as Figure 2 As shown, an outwardly protruding arc surface is provided in the middle of the outer side of the sponge pad 14. During the reciprocating movement of the sponge pad 14 relative to the electrical equipment driven by the dust removal body 11, the contact force between the arc surface area and the surface of the electrical equipment is greater. The dust in the area where the surface of the electrical equipment contacts the arc surface is pre-detached from the surface of the electrical equipment, and the area on both sides of the arc surface gathers this part of the dust to prevent the dust from floating in the air.

[0041] To enhance the gathering effect of the curved sponge pad 14 on the bottom center side, such as Figure 3As shown, multiple through-posts 15 are installed inside the sponge pad 14, and multiple first limiting grooves 111 are set on the dust removal body 11. The distance between the multiple through-posts 15 on the outer side of the sponge pad 14 is the same. The first linear electric cylinder 22 is activated, which drives the multiple through-posts 15 to retract into their respective first limiting grooves 111, so that the arc surface in the middle of the outer side of the sponge pad 14 is transformed into a plane, thereby increasing the shrinking effect of the sponge pad 14 with the arc surface set on the bottom middle side.

[0042] Example 2:

[0043] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 4 As shown, in this embodiment, the bottom of the dust collection body 31 is provided with a slide rail 41, and a slider 42 is slidably installed on the slide rail 41. The slider 42 is installed at the bottom of the dust scraper 43, and the top of the dust scraper 43 abuts against the outer side of the sponge pad 14. A second linear electric cylinder 44 for driving the slider 42 to move is installed inside the dust collection body 31, and a plurality of second limiting grooves 311 are provided on the dust collection body 31.

[0044] Start the first linear electric cylinder 22, which drives multiple through-posts 15 to extend to the bottom of their respective second limiting grooves 311, so that the arc surface in the middle of the outer side of the sponge pad 14 becomes a flat surface. Then start the second linear electric cylinder 44, which drives the slider 42 to slide back and forth on the slide rail 41, scraping the outer side of the sponge pad 14 and causing dust to fall off the surface of the sponge pad 14.

[0045] like Figure 5 As shown, the multiple scraping ridges on the scraper frame 43 have inverted trapezoidal cross sections. As the slider 42 slides back and forth in the slide rail 41, it drives the scraper frame 43 to efficiently scrape the outer side of the sponge pad 14, thereby accelerating the efficiency of removing dust from the pores of the sponge pad 14.

[0046] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.

[0047] Apart from the technical features described in the specification, the other technical features are known to those skilled in the art. To highlight the innovative features of this utility model, the other technical features will not be described in detail here.
