[0002] Electrical components such as circuit breakers and contactors inside high and low voltage distribution cabinets will generate static electricity and absorb dust during operation. If too much dust accumulates, it may affect the heat dissipation of the equipment, causing the temperature to rise, affecting the normal operation of the electrical components, and even causing faults such as short circuits, which requires dust removal inside the distribution cabinet. Common dust removal equipment includes compressed air spray guns and vacuum cleaners. At present, when cleaning the distribution cabinet, compressed air spray guns and vacuum cleaners are usually used separately.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] refer to Figure 1, an embodiment of the present application provides a dust removal component 100 that can be used for a dust removal device, including: an air blowing pipe 110, an air suction pipe 120 and a dust collecting 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 suctioning air. The dust collecting hood 130 is sleeved on the air suction pipe 120 and is used to capture dust and guide dust into the air suction pipe 120. During specific use, the dust collecting hood 130 can cover the outside of the area to be cleaned. When the air blowing pipe 110 blows air toward the position to be cleaned, the dust accumulated on the surface of the position to be cleaned flies up to form dust-containing gas, and the dust-containing gas is captured in the dust collecting hood 130. Then the dust collecting hood 130 can guide the dust-containing gas to be sucked away by the air suction pipe 120.

[0041] In some embodiments, the dust hood 130 is a flared structure, and has a first opening and a second opening along its axial direction, the first opening is used to be sleeved on the air intake pipe 120, and the size of the second opening is adjustable. That is, during the dust removal operation, the size of the opening of the dust hood 130 can be adjusted according to the size of the location to be cleaned, so that it can be suitable for different dust removal environments.

[0042] In some embodiments, the dust 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 air intake pipe 120, and two adjacent ribs 131 are connected by the dustproof cloths 132. In a specific configuration, one end of the rib 131 close to the air intake pipe 120 may be hinged to the air intake pipe 120, and under the action of an external force, one end of the rib 131 away from the air intake pipe 120 may expand or contract outward to achieve adjustment of the opening size of the dust hood 130.

[0043] Furthermore, the dustproof cloth 132 can be made of elastic cloth. This arrangement allows the dustproof cloth 132 to be retractable to adapt to the change in the opening of the dust hood 130, especially when the opening of the dust hood 130 is reduced, the dustproof cloth 132 can be prevented from folding inwards, causing dust to accumulate in the dustproof cloth 132 and unable to be sucked away, which is conducive to ensuring 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 sleeved on the air intake pipe 120 and can slide along the axial direction of the air intake 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 ribs 131. That is to say, 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 ribs 131, so that the distal end of the ribs 131 opens outward or retracts inward, thereby realizing the adjustment of the opening size of the dust hood 130.

[0045] In some embodiments, the sliding sleeve 140 may include two first curved plates 141 and two second curved plates 142. The two first curved plates 141 and the two second curved plates 142 are alternately distributed along the circumference of the air intake pipe 120, and the two first curved plates 141 and the two second curved plates 142 are respectively hinged to the corresponding connecting rods 150, and the two first curved 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, the number of the first connecting rod 150 is two, the two first connecting rods 150 are respectively located on opposite sides of the suction pipe 120, and the two first connecting rods 150 are respectively hinged to the two first curved plates 141, the number of the second connecting rods 150 is eight, the eight second connecting rods 150 are respectively located on both sides of the two first connecting rods 150, and the eight second connecting rods 150 are respectively hinged to the two second curved plates 142, that is, each second curved plate 142 is hinged to four second connecting rods 150. In specific use, the first curved plate 141 and the second curved plate 142 can slide synchronously or separately. For example, when the two second curved plates 142 slide alone, the second opening of the dust hood 130 will become oblate.

[0046] In some embodiments, a connecting mechanism is provided between adjacent first curved plates 141 and second curved plates 142. The connecting mechanism is configured to connect or disconnect adjacent first curved plates 141 and second curved plates 142. When connected, adjacent first curved plates 141 and second curved plates 142 can slide synchronously along the axial direction of the air intake pipe 120. When disconnected, adjacent first curved plates 141 and second curved plates 142 can slide separately along the axial direction of the air intake pipe 120. This configuration can facilitate the first curved plates 141 and second curved plates 142 to slide synchronously or independently.

[0047] In some embodiments, the connecting mechanism is located on the inner side of the first curved plate 141 and the second curved plate 142, and the connecting mechanism includes a first connecting body 143 and a second connecting body 144. The first connecting body 143 is arranged on the first curved plate 141 and has an insert rod 143a. The second connecting body 144 is arranged on the second curved plate 142 and has a slot 144a. Among them, the insert rod 143a can move axially (along the circumference of the suction pipe 120) relative to the first connecting body 143, and has a first position and a second position relative to the first connecting body 143. In the first position, the insert rod 143a is inserted into the slot 144a to connect the adjacent first curved plate 141 and the second curved plate 142. In the second position, the insert rod 143a withdraws from the slot 144a to disconnect the adjacent first curved plate 141 and the second curved plate 142. With this arrangement, the connecting mechanism can connect or disconnect the first curved plate 141 and the second curved plate 142.

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

[0049] In some embodiments, the connection mechanism further includes a movable plate 143b, a first spring 143c, a force 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 the end of the insertion rod 143a away from the slot 144a. The first spring 143c is sleeved on the insertion rod 143a and is located between the movable plate 143b and the first connecting body 143. The first spring 143c pushes the movable plate 143b to keep the insertion rod 143a in the second position when no external force is applied. The force block 143d is arranged on the side of the movable part away from the insertion rod 143a, and the force block 143d can be compressed to drive the insertion rod 143a to move to the first position. The fixed plate 143e is arranged on the outer wall of the suction pipe 120, and support blocks 143f are arranged at both ends of the fixed plate 143e. The rotating column 143g is arranged along the sliding direction of the sliding sleeve 140 and penetrates the first connecting body 143, and can be rotatably arranged between the supporting blocks 143f. The rotating column 143g is provided with a card slot 143g-1 along its axial direction. The threaded tube 143h is slidably sleeved on the rotating column 143g. The threaded tube 143h is provided with a card block embedded in the card slot 143g-1. The threaded sleeve 145 can rotate synchronously when the rotating column 143g rotates circumferentially. The push block 143i is threadedly connected to the threaded tube 143h. The push block 143i can move along the first direction of the axial direction of the threaded tube 143h when the threaded tube 143h rotates circumferentially, so as to squeeze the force block 143d to drive the insertion rod 143a to move to the first position. That is to say, in the initial position, the insertion rod 143a is maintained in the second position, so that the connection between the first arc plate 141 and the second arc plate 142 is disconnected. 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 engagement between the clamping groove 143g-1 and the clamping block), the threaded tube 143h can rotate synchronously with the rotating column 143g. At the same time, the threaded tube 143h can be threadedly matched with the push block 143i, so that the push block 143i moves 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 axial direction of the threaded tube 143h, so that 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 along the circumferential direction of the air intake pipe 120 to switch positions, the push block 143i can press the force block 143d by the side when moving. For example, the side of the push block 143i is an inclined surface, and when the push block 143i moves in the first direction, the force block 143d can move along the inclined surface, and drive the insertion rod 143a to move to the first position under the action of the squeezing force of the inclined surface, so as to realize the connection between the first arc plate 141 and the second arc plate 142.

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

[0052] In some embodiments, the fixing plate 143e is provided with a plurality of limit grooves 143e-1 along the moving direction of the push block 143i. The connection mechanism also includes a limit rod 143j, which is movably provided on the first connection body 143 and has a third position and a fourth position for axial movement relative to the first connection body 143. In the third position, the limit rod 143j is inserted into the limit groove 143e-1, and in the fourth position, the limit rod 143j exits the limit groove 143e-1. In specific use, inserting the limit block into the limit groove 143e-1 can limit the axial sliding of the first arc plate 141 along the suction pipe 120, so that the first arc plate 141 can be limited to avoid the position change of the first arc plate 141 when the second arc plate 142 slides alone, resulting in deformation of the opening of the dust cover 130. Of course, since there are multiple limiting grooves 143e-1 and they are arranged along the moving direction of the push block 143i, the limiting rod 143j can cooperate with different limiting grooves 143e-1 to limit the first arc plate 141 to different positions relative to the fixed plate 143e.

[0053] In some embodiments, the connection 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 that is away from the limiting groove 143e-1. The stabilizing column 143l is disposed on the first connection body 143, and the stabilizing column 143l and the stabilizing block 143k are slidably matched to guide the limiting rod 143j. This arrangement can guide the limiting rod 143j, prevent the limiting rod 143j from deflecting during movement, and is conducive to ensuring the reliability of the structure.

[0054] In some embodiments, the connection mechanism further includes a second spring 143m and a squeeze rod 143n. The second spring 143m is sleeved on the stabilizing column 143l and connected between the stabilizing block 143k and the first connecting body 143. The second spring 143m pulls the stabilizing block 143k when not acted upon by an external force to keep the limiting rod 143j in the third position. The squeeze rod 143n is connected to the push block 143i. The squeeze rod 143n can act on the limiting rod 143j to make it withdraw from the limiting groove 143e-1 when the push block 143i squeezes the force-bearing block 143d. That is to say, when the first curved plate 141 and the second curved 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 first curved plate 141 from sliding relative to the air intake pipe 120. When the push block 143i moves in the first direction to squeeze the force block 143d, the insertion 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 squeezing rod 143n connected to the push block 143i can act on the limiting rod 143j to make it withdraw from 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] Further, in order to release the limitation of the first curved plate 141, the limiting rod 143j may have a force groove 143j-1 extending along the moving direction of the push block 143i, and the extrusion rod 143n may have an inclined surface. During use, when the push block 143i squeezes the force block 143d, the extrusion rod 143n may be inserted into the force groove 143j-1, and, during the process of the extrusion rod 143n being inserted into the force groove 143j-1, the limiting rod 143j may move along the inclined surface of the extrusion rod 143n to exit the limiting groove 143e-1, thereby releasing the limitation of the first curved 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 curved plate 142. The threaded sleeve 145 can drive the second curved plate 142 to move axially along the suction pipe 120 when the threaded sleeve 145 rotates circumferentially relative to the suction pipe 120. Specifically, the threaded sleeve 145 is threadedly matched with the second curved plate 142, and when the threaded sleeve 145 rotates circumferentially, the second curved plate 142 can be moved axially along the threaded sleeve 145. Therefore, in specific use, the second curved 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 hood 130.

[0057] In this embodiment, a slide rail is provided on the outer wall of the air intake pipe 120, and the slide rail is passed through the second connecting body 144 and slidably cooperates with the second connecting body 144. This arrangement can ensure that the second arc plate 142 slides independently on the one hand, and can limit the sliding direction of the second arc plate 142 on the other hand, so as to prevent the second arc plate 142 from rotating relative to the air intake pipe 120 when the threaded sleeve 145 is rotated, thereby affecting the driving effect of the threaded sleeve 145.

[0058] In this embodiment, the outer wall of the rib plate 131 is provided with a slide groove 133 along its length direction, and a slider 134 is provided in the slide groove 133, and the slider 134 is hinged to the second end of the connecting rod 150. During use, when the connecting rod 150 drives the rib plate 131 to open outward, the slider 134 can slide in the slide groove 133. Compared with the way that the connecting rod 150 is directly hinged to the rib plate 131, this can reduce the rotation angle of the connecting rod 150 when the opening angle of the rib plate 131 is the same, thereby avoiding interference between the connecting rod 150 and the threaded sleeve 145.

[0059] The dust collecting hood 130 of the dust removal assembly 100 of the embodiment of the present application can cover the outside of the area to be cleaned, so that the dust-containing gas generated by the blowing pipe 110 can be captured in the dust collecting hood 130, and then the dust-containing gas can be sucked away by the suction pipe 120 under the guidance of the dust collecting hood 130, so that the blowing and dust suction functions can be achieved at the same time, which is conducive to improving the problem of unsatisfactory cleaning effect of existing cleaning equipment. In addition, since the second opening size of the dust collecting hood 130 is adjustable, the user can adjust the opening size of the dust collecting hood 130 according to the situation of the location to be cleaned, so that it can be suitable for dust removal environments with different space sizes.

The dust removal component 100 includes an air blowing pipe 110, an air suction pipe 120 and a dust collecting hood 130. When performing dust removal operations, the dust collecting hood 130 can be covered outside the area to be cleaned, so that the dust-containing gas generated by the air blowing pipe 110 can be captured in the dust collecting hood 130, and then the dust-containing gas can be sucked away by the air suction pipe 120 under the guidance of the dust collecting hood 130, so that the blowing and dust collection functions can be achieved at the same time, which is conducive to improving the problem of unsatisfactory cleaning effect of existing cleaning equipment. In addition, since the size of the second opening of the dust collecting hood 130 is adjustable, the user can adjust the opening size of the dust collecting hood 130 according to the situation of the position to be cleaned, so that it can be suitable for dust removal environments with different space sizes.

[0061] In some embodiments, the electrical equipment dust removal device also includes an air supply component 200, which is used to connect the blowing pipe 110 and the suction pipe 120 of the dust removal component 100, so that the blowing pipe 110 can blow air and the suction pipe 120 can suck air, thereby realizing the blowing and dust suction functions at the same time.

[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 air 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 air suction pipe 120. In specific use, the fan 210 can send air to the air blowing pipe 110 through the air outlet pipe 220, so that the air blowing pipe 110 blows air toward the position to be cleaned. At the same time, the fan 210 can form a negative pressure in the air inlet pipe 230 and the air suction pipe 120, so that the air suction pipe 120 sucks air, and sends the dust-containing air into the fan 210 through the air inlet pipe 230, thereby achieving the blowing and dust collection of the area to be cleaned.

[0063] In some embodiments, a filter is disposed in the air inlet pipe 230. When in use, the filter can filter dust in the dust-laden gas to prevent dust from entering the inside of 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 inlet pipe 230 and is located on the side of the filter screen close to the air intake pipe 120. In specific use, the dust exhaust pipe 240 can discharge the dust filtered out by the filter screen to prevent dust from accumulating in the air inlet pipe 230 and affecting the air intake effect.
