Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to an anti-static dust removal device for electrical control cabinets. Background Technology

[0002] Electrical control cabinets are widely used in industrial automation, power systems, and other fields. The interior of these cabinets contains a dense concentration of electronic components, which easily attract dust and particles from the air during long-term operation. Dust accumulation not only affects heat dissipation, reducing equipment lifespan and reliability, but can also lead to serious malfunctions such as short circuits, signal interference, and poor contact, threatening the safe and stable operation of the equipment.

[0003] Existing technology, such as CN219421133U, provides an anti-static dust removal device for an electrical control cabinet, relating to the field of control cabinet dust removal technology. The inner wall of the cabinet is fixedly connected to an anti-static PC board, and an ion generator and an electrostatic eliminator are installed inside the cabinet. This invention, because the horizontal tube is positioned above and below the anti-static PC board, and the conical nozzle evenly disperses the ions around the anti-static PC board, ensures that a large number of positive and negative ions are not blocked by electrical components. This allows a large number of positive and negative ions to be quickly and evenly blown onto the surface of the working components to neutralize static electricity, achieving both static removal and dust removal, thereby improving dust removal performance.

[0004] The jet nozzles are fixed in specific positions inside the cabinet, forming a "fixed-point" jet. This fixed structure results in a very limited jet coverage area, making it impossible to dynamically adjust according to the actual distribution of components inside the cabinet. With fixed jet points and a small coverage area, areas far from the jet points, densely populated areas of components, or complex structures inside the cabinet are prone to becoming dust removal blind spots. The limited dust removal area makes it difficult to effectively remove dust, thus weakening the dust removal effect. Utility Model Content

[0005] In view of the problem that the existing jet holes are fixed in a specific position inside the cabinet and the jet coverage is very limited, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an anti-static dust removal device for electrical control cabinets, the purpose of which is to: vertically raise and lower the air jet hole inside the cabinet to expand the coverage area of ​​the air jet hole.

[0007] To solve the above technical problems, this utility model provides the following technical solution: an anti-static dust removal device for an electrical control cabinet, including a U-shaped tube and a vertically sliding linkage lifting assembly. An ion fan and an air compressor are respectively installed on both sides of the movable end of the linkage lifting assembly. A T-shaped tube connects the air outlet ends of the ion fan and the air compressor. A connecting pipe is fixedly connected between the air inlet end of the U-shaped tube and the air outlet end of the T-shaped tube. Multiple air jet holes are opened on the inner wall surface of the U-shaped tube.

[0008] A dust collection assembly, comprising a dust removal fan, wherein a filter bag is detachably installed at the dust outlet end of the dust removal fan.

[0009] As an improved technical solution, it also includes two limiting wheels, through which the connecting pipe is guided and bent into an inverted "U" shape.

[0010] As an improved technical solution, pipe connecting blocks are welded to both ends of the U-shaped tube. A first slider is fixed to the end of the pipe connecting block away from the U-shaped tube. A first vertical guide rail is provided in the sliding cavity of the first slider, and the U-shaped tube slides vertically between the four first vertical guide rails.

[0011] As an improved technical solution, the linkage lifting assembly includes two second vertical guide rails, an L-shaped lifting plate is vertically slidably installed between the two second vertical guide rails, a transmission block is welded to one side of the vertical end of the L-shaped lifting plate, a lead screw is threadedly installed on the transmission block through a threaded hole, and the top of the lead screw is fixedly connected to the drive end of a servo motor.

[0012] As an improved technical solution, a second slider is installed on both sides of the vertical end of the L-shaped lifting plate, and the second slider slides on the second vertical guide rail.

[0013] As an improved technical solution, the dust collection assembly further includes a perforated block, and the dust removal fan is fixed on the outer side of the perforated block. At the same time, the dust inlet end of the dust removal fan and the inner hole on the perforated block are coaxially arranged.

The air jet coverage is more comprehensive, and the expansion of the coverage area and elimination of dead corners directly improves the comprehensiveness and thoroughness of dust removal.

[0016] 2. In this utility model, the dust removal fan generates increased negative pressure suction to absorb the dust inside the U-shaped tube, and sends it into the filter bag for collection through the L-shaped connecting pipe.

The U-shaped tube 1 naturally covers the two side wall areas inside the cabinet and the area connecting the two sides, forming a three-dimensional jet structure that is similar to a "door frame". Compared with single-point or single-line fixed jet, the U-shaped tube 1 can spray anti-static airflow in multiple directions at the same time, which greatly expands the effective range of a single jet tube. It also includes a vertically sliding linkage lifting component 6, which is set on one side of the electrical control cabinet. An ion fan 7 and an air compressor 8 are respectively installed on both sides of the movable end of the linkage lifting component 6. A T-shaped tube 9 connects the air outlet ends of the ion fan 7 and the air compressor 8. A connecting pipe 2 is fixedly connected between the air inlet end of the U-shaped tube 1 and the air outlet end of the T-shaped tube 9. Multiple jet holes 10 are opened on the inner wall surface of the U-shaped tube 1.

[0027] The dust collection assembly 4 includes a dust removal fan 42, and a filter bag 44 is detachably installed at the dust outlet end of the dust removal fan 42.

[0028] By using the linkage lifting assembly 6 to drive the U-shaped tube 1 to continue vertically lifting and lowering inside the electrical control cabinet, the air jet coverage of the U-shaped tube 1 is no longer limited to a fixed height level, but can dynamically sweep the entire vertical space inside the cabinet from bottom to top. The air jet coverage is more comprehensive, and the expansion of the coverage area and elimination of dead corners directly improve the comprehensiveness and thoroughness of dust removal.

[0029] It also includes two limit wheels 5, which are fixed to the top of the electrical control cabinet. The connecting pipe 2 is guided and bent into an inverted "U" shape by the two limit wheels 5.

[0030] Both ends of the U-shaped tube 1 are welded with tube connecting blocks 11. The end of the tube connecting block 11 away from the U-shaped tube 1 is fixed with a first slider 12. The sliding cavity of the first slider 12 is provided with a first vertical guide rail 3. The U-shaped tube 1 slides vertically between four first vertical guide rails 3. The first slider 12 slides along the direction of the first vertical guide rail 3. The first vertical guide rail 3 is fixed inside the electronic controller cabinet.

[0031] The linkage lifting assembly 6 includes two second vertical guide rails 62, which are fixed to the side of the U-shaped tube 1. An L-shaped lifting plate 61 is vertically slidably installed between the two second vertical guide rails 62. The ion fan 7 and the air compressor 8 are fixed to the top of the horizontal end of the L-shaped lifting plate 61. A transmission block 64 is welded to one side of the vertical end of the L-shaped lifting plate 61. A lead screw 63 is threadedly installed on the transmission block 64 through a threaded hole. The top of the lead screw 63 is fixedly connected to the drive end of a servo motor 65. The servo motor 65 is fixed to the side of the electrical control cabinet by a bracket.

[0032] The L-shaped lifting plate 61 has a second slider installed on both sides of its vertical end, and the second slider slides on the second vertical guide rail 62.

[0033] The dust collection assembly 4 also includes a perforated block 41, and a dust removal fan 42 is fixed on the outer side of the perforated block 41. The dust inlet end of the dust removal fan 42 is coaxially arranged with the inner hole on the perforated block 41. The perforated block 41 is fixed on the other side of the electrical control cabinet. The electrical control cabinet has a through hole that communicates with the dust removal fan 42. An L-shaped connecting pipe 43 is fixedly installed on the dust removal end of the dust removal fan 42, and a filter bag 44 is installed on the dust outlet end of the L-shaped connecting pipe 43. The dust removal fan 42 generates a stronger negative pressure suction force to absorb the dust inside the U-shaped pipe 1 and send it into the filter bag 44 through the L-shaped connecting pipe 43 for collection. The dust inside the electrical control cabinet is collected and stored in the filter bag 44 to prevent secondary pollution of the electronic components inside the electrical control cabinet by the dust.

[0034] The working principle of this utility model is as follows: by sliding 13 on the first vertical guide rail 3, the U-shaped tube 1 is slidably installed between the four first vertical guide rails 3, and the U-shaped tube 1 can be vertically raised and lowered along the guide of the first vertical guide rail 3;

[0035] After the air compressor 8 compresses the air, it is sent into the interior of the connecting pipe 2 through the T-shaped pipe 9. At the same time, the ion fan 7 generates charged ions and sends them into the interior of the connecting pipe 2 through the T-shaped pipe 9. That is, the charged ions and compressed air mix inside the connecting pipe 2 and finally enter the interior of the U-shaped pipe 1 and are sprayed into the interior of the electrical control cabinet through the jet hole 10. A large number of positive and negative ions are evenly blown onto the surface of the working components to neutralize static electricity, realize static electricity removal, and the compressed air also lifts up the surface dust to remove dust.

[0036] While the U-shaped tube 1 is spraying air, the servo motor 65 drives the lead screw 63 to rotate. Under the threaded transmission action of the lead screw 63 and the threaded hole on the transmission block 64, the L-shaped lifting plate 61 is driven to move downward through the transmission block 64. Under the pulling action of the connecting pipe 2, the U-shaped tube 1 is pulled upward inside the electrical control cabinet. Conversely, the L-shaped lifting plate 61 moves upward, and under the gravity of the U-shaped tube 1, the U-shaped tube 1 moves downward inside the electrical control cabinet.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
