Description

Technical Field

[0001] This application relates to the field of dust removal technology, and more specifically, to a dust removal component and a dust removal device for electrical equipment. Background Technology

[0002] Electrical components inside high and low voltage switchgear, such as circuit breakers and contactors, generate static electricity during operation, attracting dust. Excessive dust accumulation can impair heat dissipation, leading to overheating, affecting the normal operation of electrical components, and even causing short circuits. Therefore, dust removal is necessary. Common dust removal equipment includes compressed air spray guns and vacuum cleaners. Currently, compressed air spray guns and vacuum cleaners are usually used separately when cleaning switchgear. Using a compressed air spray gun to blow air through the cabinet causes dust to fly around, polluting the surrounding air and potentially causing dust to re-settle in already cleaned areas or hard-to-reach corners. Using a vacuum cleaner alone is insufficient to completely clean dust from hard-to-reach areas, resulting in unsatisfactory cleaning. Therefore, a device that can simultaneously perform blowing and vacuuming functions is needed to solve these problems. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] refer to Figure 1This application provides a dust removal assembly 100 for use in a dust removal device, including: an air blowing pipe 110, an air suction pipe 120, and a dust collection hood 130. The air blowing pipe 110 is used for blowing air. The air suction pipe 120 is sleeved on the air blowing pipe 110 and is used for suction. The dust collection hood 130 is sleeved on the air suction pipe 120 and is used for capturing dust and guiding dust into the air suction pipe 120. In practical use, the dust collection hood 130 can cover the area to be cleaned. When the air blowing pipe 110 blows air onto the area to be cleaned, the dust accumulated on the surface of the area to be cleaned is thrown up to form dust-laden gas, which is captured inside the dust collection hood 130. Subsequently, the dust collection hood 130 can guide the dust-laden gas so that it is sucked away by the air suction pipe 120.

[0041] In some embodiments, the dust collection hood 130 has a flared structure, with a first opening and a second opening along its axial direction. The first opening is used to fit over the suction pipe 120, and the size of the second opening is adjustable. That is, during dust removal operations, the opening size of the dust collection hood 130 can be adjusted according to the size of the area to be cleaned, making it suitable for different dust removal environments.

[0042] In some embodiments, the dust collection hood 130 may include a plurality of ribs 131 and a plurality of dustproof cloths 132. The plurality of ribs 131 and the plurality of dustproof cloths 132 are alternately distributed along the circumference of the suction pipe 120, and adjacent ribs 131 are connected by dustproof cloths 132. In a specific configuration, the end of the rib 131 near the suction pipe 120 may be hinged to the suction pipe 120, and under the action of external force, the end of the rib 131 away from the suction pipe 120 may expand or contract outward to adjust the opening size of the dust collection hood 130.

[0043] Furthermore, the dust cover 132 can be made of elastic fabric. This design allows the dust cover 132 to stretch and adjust to changes in the opening of the dust collection hood 130. In particular, when the opening of the dust collection hood 130 is reduced, it prevents the dust cover 132 from folding inward, which would cause dust to accumulate in the dust cover 132 and not be sucked away, thus helping to ensure the cleaning effect.

[0044] In some embodiments, the dust removal assembly 100 further includes a sliding sleeve 140 and a plurality of connecting rods 150. The sliding sleeve 140 is fitted onto the suction pipe 120 and is slidable along the axial direction of the suction pipe 120. The first ends of the plurality of connecting rods 150 are respectively hinged to the sliding sleeve 140, and the second ends of the plurality of connecting rods 150 are respectively hinged to the plurality of stiffening plates 131. That is, before performing the dust removal operation, by sliding the sliding sleeve 140, the connecting rods 150 can apply a pulling force or a pushing force to the stiffening plates 131, so that the distal ends of the stiffening plates 131 open outward or retract inward, thereby adjusting the opening size of the dust collection hood 130.

[0045] In some embodiments, the sliding sleeve 140 may include two first arc-shaped plates 141 and two second arc-shaped plates 142. The two first arc-shaped plates 141 and the two second arc-shaped plates 142 are alternately distributed along the circumference of the suction pipe 120. The two first arc-shaped plates 141 and the two second arc-shaped plates 142 are respectively hinged to corresponding connecting rods 150, and the two first arc-shaped plates 141 are respectively hinged to two oppositely arranged connecting rods 150. For example, the connecting rod 150 includes a first connecting rod 150 and a second connecting rod 150. There are two first connecting rods 150, located on opposite sides of the suction pipe 120, and each hinged to one of the two first arc-shaped plates 141. There are eight second connecting rods 150, located on opposite sides of the two first connecting rods 150, and each hinged to one of the two second arc-shaped plates 142. That is, each second arc-shaped plate 142 is hinged to four second connecting rods 150. In practical use, the first arc-shaped plates 141 and the second arc-shaped plates 142 can slide synchronously or independently. For example, when the two second arc-shaped plates 142 slide independently, the second opening of the dust collection hood 130 becomes a flattened oval shape.

[0046] In some embodiments, a connecting mechanism is provided between adjacent first arc-shaped plates 141 and second arc-shaped plates 142. The connecting mechanism is configured to connect or disconnect adjacent first arc-shaped plates 141 and second arc-shaped plates 142. When connected, adjacent first arc-shaped plates 141 and second arc-shaped plates 142 can slide synchronously along the axial direction of the suction pipe 120. When disconnected, adjacent first arc-shaped plates 141 and second arc-shaped plates 142 can slide separately along the axial direction of the suction pipe 120. This configuration facilitates the synchronous or independent sliding of the first arc-shaped plates 141 and second arc-shaped plates 142.

[0047] In some embodiments, the connecting mechanism is located inside the first arcuate plate 141 and the second arcuate plate 142, and includes a first connecting body 143 and a second connecting body 144. The first connecting body 143 is disposed on the first arcuate plate 141 and has a plug 143a. The second connecting body 144 is disposed on the second arcuate plate 142 and has a slot 144a. The plug 143a is axially movable relative to the first connecting body 143 (along the circumferential direction of the suction pipe 120) and has a first position and a second position relative to the first connecting body 143. In the first position, the plug 143a is inserted into the slot 144a to connect adjacent first arcuate plates 141 and second arcuate plates 142. In the second position, the plug 143a is withdrawn from the slot 144a to disconnect adjacent first arcuate plates 141 and second arcuate plates 142. This configuration enables the connecting mechanism to connect or disconnect the first arcuate plates 141 and second arcuate plates 142.

[0048] In this embodiment, the first connecting body 143 can be a box. In a specific setting, the insertion rod 143a is set inside the box, and the insertion rod 143a can extend out from the through hole on the side of the box to be inserted into the slot 144a.

[0049] In some embodiments, the connecting mechanism further includes a movable plate 143b, a first spring 143c, a force-bearing block 143d, a fixed plate 143e, a support block 143f, a rotating column 143g, a threaded tube 143h, and a push block 143i. The movable plate 143b is connected to one end of the insertion rod 143a away from the slot 144a. The first spring 143c is sleeved on the insertion rod 143a and located between the movable plate 143b and the first connecting body 143. When no external force is applied, the first spring 143c pushes the movable plate 143b to keep the insertion rod 143a in the second position. The force-bearing block 143d is disposed on the side of the movable part away from the insertion rod 143a. The force-bearing block 143d can be compressed to drive the insertion rod 143a to move towards the first position. The fixed plate 143e is disposed on the outer wall of the suction pipe 120, and support blocks 143f are disposed at both ends of the fixed plate 143e. A rotating column 143g is disposed along the sliding direction of the sliding sleeve 140 and passes through the first connecting body 143, and is rotatably disposed between the support blocks 143f. The rotating column 143g has a groove 143g-1 along its axial direction. A threaded tube 143h is slidably sleeved on the rotating column 143g, and the threaded tube 143h has a locking block that embeds into the groove 143g-1. The threaded sleeve 145 can rotate synchronously when the rotating column 143g rotates circumferentially. A push block 143i is threadedly connected to the threaded tube 143h. The push block 143i can move along the first direction of the threaded tube 143h's axial direction when the threaded tube 143h rotates circumferentially, thereby pressing the force-bearing block 143d to drive the insertion rod 143a to the first position. That is, in the initial position, the insertion rod 143a remains in the second position, thus disconnecting the connection between the first arc-shaped plate 141 and the second arc-shaped plate 142. At this time, due to the sliding fit between the threaded tube 143h and the rotating column 143g, the first arc plate 141 can slide independently along the axial direction of the rotating column 143g (i.e., the sliding direction of the sliding sleeve 140). When the rotating column 143g is driven to rotate circumferentially by the built-in motor, due to the limiting fit between the rotating column 143g and the threaded tube 143h (the slot 143g-1 and the locking block engage), the threaded tube 143h can rotate synchronously with the rotating column 143g. At the same time, the threaded tube 143h can be threadedly engaged with the push block 143i, so that the push block 143i can move along the first direction of the axial direction of the threaded tube 143h. When the push block 143i moves in the first direction, it can squeeze the force block 143d, so that the force block 143d can drive the insertion rod 143a to move to the first position through the movable plate 143b. Of course, when the rotating column 143g rotates in the opposite direction, the push block 143i can move in the second direction along the axial direction of the threaded tube 143h. In this way, the pressure of the push block 143i disappears, the force block 143d can be reset under the action of the first spring 143c, and drive the insertion rod 143a back to the second position.

[0050] In this embodiment, since the insertion rod 143a needs to move circumferentially along the suction pipe 120 to switch positions, the push block 143i can exert lateral pressure on the force-receiving block 143d during movement. For example, the side of the push block 143i is an inclined surface. When the push block 143i moves in the first direction, the force-receiving block 143d can move along the inclined surface and, under the pressure of the inclined surface, drive the insertion rod 143a to move to the first position, thereby achieving the connection between the first arc plate 141 and the second arc plate 142.

[0051] In this embodiment, the movable plate 143b, the first spring 143c, the force-bearing block 143d, the threaded tube 143h, and the push block 143i can be located inside the first connecting body 143.

[0052] In some embodiments, the fixed plate 143e is provided with a plurality of limiting grooves 143e-1 along the moving direction of the push block 143i. The connecting mechanism also includes a limiting rod 143j, which is movably disposed on the first connecting body 143 and has a third position and a fourth position that can move axially relative to the first connecting body 143. In the third position, the limiting rod 143j is inserted into the limiting groove 143e-1, and in the fourth position, the limiting rod 143j is removed from the limiting groove 143e-1. In practical use, inserting the limiting block into the limiting groove 143e-1 can restrict the sliding of the first arc plate 141 along the axial direction of the suction pipe 120. In this way, the first arc plate 141 can be limited to avoid the first arc plate 141 changing position when the second arc plate 142 slides alone, which would cause the opening of the dust collection hood 130 to deform. Of course, since there are multiple limiting grooves 143e-1 and they are set along the moving direction of the push block 143i, the limiting rod 143j can cooperate with different limiting grooves 143e-1 to restrict the first arc plate 141 to different positions relative to the fixed plate 143e.

[0053] In some embodiments, the connecting mechanism further includes a stabilizing block 143k and a stabilizing column 143l. The stabilizing block 143k is disposed at one end of the limiting rod 143j opposite to the limiting groove 143e-1. The stabilizing column 143l is disposed on the first connecting body 143, and the stabilizing column 143l slides in cooperation with the stabilizing block 143k to guide the limiting rod 143j. This arrangement can guide the limiting rod 143j, prevent the limiting rod 143j from deviating during movement, and help ensure the reliability of the structure.

[0054] In some embodiments, the connecting mechanism further includes a second spring 143m and a pressing rod 143n. The second spring 143m is sleeved on the stabilizing post 143l and connected between the stabilizing block 143k and the first connecting body 143. When no external force is applied, the second spring 143m pulls the stabilizing block 143k to keep the limiting rod 143j in the third position. The pressing rod 143n is connected to the push block 143i. When the push block 143i presses the force-bearing block 143d, the pressing rod 143n acts on the limiting rod 143j to make it exit the limiting groove 143e-1. That is, when the first arc plate 141 and the second arc plate 142 are disconnected, the limiting rod 143j can be inserted into the limiting groove 143e-1 under the action of the second spring 143m to limit the sliding of the first arc plate 141 relative to the suction pipe 120. When the push block 143i moves in the first direction to press the force block 143d, the insert rod 143a is inserted into the slot 144a, so that the first arc plate 141 and the second arc plate 142 are connected. At the same time, the pressing rod 143n connected to the push block 143i can act on the limiting rod 143j to make it exit the limiting groove 143e-1. At this time, the first arc plate 141 is released from the limit and can slide synchronously with the second arc plate 142.

[0055] Furthermore, in order to release the restriction on the first arc-shaped plate 141, the limiting rod 143j may have a force-receiving groove 143j-1 extending along the moving direction of the push block 143i, and the pressing rod 143n may have an inclined surface. During use, when the push block 143i presses the force-receiving block 143d, the pressing rod 143n may be inserted into the force-receiving groove 143j-1, and during the process of the pressing rod 143n being inserted into the force-receiving groove 143j-1, the limiting rod 143j may move along the inclined surface of the pressing rod 143n to exit the limiting groove 143e-1, thereby releasing the restriction on the first arc-shaped plate 141.

[0056] In some embodiments, the sliding sleeve 140 further includes a threaded sleeve 145, which is sleeved on the sliding sleeve 140 and threadedly connected to the second arc-shaped plate 142. The threaded sleeve 145 can drive the second arc-shaped plate 142 to move axially along the suction pipe 120 when it rotates circumferentially relative to the suction pipe 120. Specifically, the threaded sleeve 145 is threadedly engaged with the second arc-shaped plate 142. When the threaded sleeve 145 rotates circumferentially, the second arc-shaped plate 142 can be moved axially along the threaded sleeve 145. Therefore, in practical use, the second arc-shaped plate 142 can be driven to slide axially along the suction pipe 120 by rotating the threaded sleeve 145, thereby changing the opening size or shape of the dust collection hood 130.

[0057] In this embodiment, a slide rail is provided on the outer wall of the suction pipe 120. The slide rail passes through the second connecting body 144 and slides in cooperation with the second connecting body 144. This arrangement ensures that the second arc-shaped plate 142 slides independently, while also restricting the sliding direction of the second arc-shaped plate 142. This prevents the second arc-shaped plate 142 from rotating relative to the suction pipe 120 when rotating the threaded sleeve 145, thus affecting the driving effect of the threaded sleeve 145.

[0058] In this embodiment, a groove 133 is provided on the outer wall of the stiffening plate 131 along its length, and a slider 134 is provided in the groove 133. The slider 134 is hinged to the second end of the connecting rod 150. During use, when the connecting rod 150 drives the stiffening plate 131 to open outward, the slider 134 can slide in the groove 133. Compared with the direct hinge of the connecting rod 150 to the stiffening plate 131, this reduces the rotation angle of the connecting rod 150 while keeping the opening angle of the stiffening plate 131 the same, thereby avoiding interference between the connecting rod 150 and the threaded sleeve 145.

[0059] The dust removal assembly 100 of this application embodiment has a dust collection hood 130 that can cover the area to be cleaned, so that the dust-laden gas generated by the blowing pipe 110 can be captured inside the dust collection hood 130. Subsequently, the dust-laden gas can be sucked away by the suction pipe 120 under the guidance of the dust collection hood 130, thereby realizing the functions of blowing and suction simultaneously, which helps to improve the problem of unsatisfactory cleaning effect of existing cleaning equipment. In addition, since the size of the second opening of the dust collection hood 130 is adjustable, the user can adjust the size of the opening of the dust collection hood 130 according to the situation of the area to be cleaned, so that it can be adapted to dust removal environments of different sizes.

[0060] refer to Figure 9 This application also provides an electrical equipment dust removal device, including a dust removal assembly 100. The dust removal assembly 100 includes a blowing pipe 110, a suction pipe 120, and a dust collection hood 130. During dust removal, the dust collection hood 130 can cover the area to be cleaned, allowing the dust-laden gas generated by the blowing pipe 110 to be captured within the dust collection hood 130. Subsequently, the dust-laden gas can be drawn away by the suction pipe 120 under the guidance of the dust collection hood 130, thus simultaneously achieving blowing and suction functions, which helps to improve the problem of unsatisfactory cleaning effects of existing cleaning equipment. Furthermore, since the size of the second opening of the dust collection hood 130 is adjustable, the user can adjust the opening size of the dust collection hood 130 according to the conditions of the area to be cleaned, making it suitable for dust removal environments of different sizes.

[0061] In some embodiments, the electrical equipment dust removal device further includes an air supply assembly 200 for connecting the air blowing pipe 110 and the air suction pipe 120 of the dust removal assembly 100, so that the air blowing pipe 110 blows air and the air suction pipe 120 sucks air, thereby simultaneously realizing the functions of blowing and dust removal.

[0062] In some embodiments, the air supply assembly 200 includes a fan 210, an air outlet pipe 220, and an air inlet pipe 230. The air outlet pipe 220 is connected between the air outlet of the fan 210 and the air inlet of the blowing pipe 110, and the air inlet pipe 230 is connected between the air inlet of the fan 210 and the air outlet of the suction pipe 120. In practical use, the fan 210 can send air to the blowing pipe 110 through the air outlet pipe 220, so that the blowing pipe 110 blows air towards the area to be cleaned. At the same time, the fan 210 can create a negative pressure in the air inlet pipe 230 and the suction pipe 120, so that the suction pipe 120 draws in air, and sends the dust-laden air into the fan 210 through the air inlet pipe 230, thereby realizing the blowing and vacuuming of the area to be cleaned.

[0063] In some embodiments, a filter screen is provided inside the air intake pipe 230. In actual use, the filter screen can filter dust in the dust-laden gas to prevent dust from entering the fan 210 and affecting the operation of the fan 210.

[0064] In some embodiments, the air supply assembly 200 further includes a dust exhaust pipe 240, which is connected to the bottom of the air intake pipe 230 and located on the side of the filter near the intake pipe 120. In actual use, the dust exhaust pipe 240 can discharge the dust filtered by the filter to prevent dust from accumulating in the air intake pipe 230 and affecting the air intake effect.
