Description

Technical Field

[0002] In industrial production and automation control, the stable operation of electrical automation equipment is directly related to production efficiency, product quality, and system safety. However, in real-world operating environments, equipment is constantly exposed to complex conditions such as dust, oil, and humidity, leading to the continuous accumulation of dust in key areas such as circuit boards, heat sinks, and mechanical structures. This dust accumulation can pose multiple risks: First, dust coverage can reduce heat dissipation efficiency, exacerbate thermal degradation of electronic components, and even trigger overheating protection shutdowns. Second, conductive dust can easily cause circuit shorts and signal interference, while corrosive dust in humid environments can accelerate corrosion of metal components and insulation degradation. Control cabinets, as core components in electrical automation systems, house key electrical components such as PLCs, inverters, and relays. Their operating status directly impacts the stability and reliability of the entire equipment. However, due to the complex industrial environment, dust, oil, and other contaminants are highly susceptible to accumulation inside control cabinets. Long-term dust accumulation not only hinders heat dissipation, leading to component overheating and failure, but can also cause hazards such as short circuits and poor electrical connections. Therefore, regular, effective dust removal and maintenance of control cabinets is crucial to ensuring the long-term stable operation of automation equipment.

Figure 4 A schematic structural diagram of a first linear moving component provided in an embodiment of the present invention, Figure 5 A schematic diagram of the connection between the brush and the connecting rod provided in an embodiment of the present invention.

[0038] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a dust removal device for electrical automation equipment, including: a clamping part 2, a dust removing part 3, a first linear moving part 4 and a second linear moving part 5, the clamping part 2 is connected to the moving end of the first linear moving part 4, the first linear moving part 4 is vertically arranged and detachably connected to the side wall of the control cabinet 1, and the clamping part 2 clamps the side wall of the control cabinet 1; the clamping part 2 includes: a first clamping plate 21, a second clamping plate 22, a connecting plate 23 and an adjusting screw 24, the clamping sides of the first clamping plate 21 and the second clamping plate 22 are rotatably connected with a plurality of wheels 25, the first clamping plate 21 is fixedly connected to the first side of the connecting plate 23, the second clamping plate 22 is slidingly connected to the first side of the connecting plate 23, and the adjusting screw 24 passes through the first clamping plate 21 and the second clamping plate 22 in sequence for adjusting the distance between the first clamping plate 21 and the second clamping plate 22; the second linear moving part 5 is horizontally arranged, the second side of the connecting plate 23 is connected to the fixed end of the second linear moving part 5, and the dust removing part 3 is connected to the moving end of the second linear moving part 5.

[0039] Specifically, the first linear moving component 4 drives the clamping plate to move up and down, thereby driving the connecting plate 23 to move up and down. The connecting plate 23 then drives the second linear moving component 5 to move up and down as a whole, and the dust removal component 3 also moves up and down with the second linear moving component 5. The first clamping plate 21 and the second clamping plate 22 are located on both sides of the side wall of the control cabinet 1 and are parallel to the side wall of the control cabinet 1. The first clamping plate 21 and the second clamping plate 22 are perpendicular to each other. The wheel 25 is connected between the first clamping plate 21, the second clamping plate 22 and the side wall of the control cabinet 1. The adjusting screw 24 passes through the first clamping plate 21 and the second clamping plate 22. The distance between the two clamping plates is adjusted by screwing in and out. The wheel 25 is installed on the bearing on the clamping side of the two clamping plates and can rotate freely to reduce friction with the side wall of the control cabinet 1. Rotating the adjusting screw 24 pushes the second clamping plate 22 to slide and cooperate with the first clamping plate 21 to clamp the side wall of the control cabinet 1. After clamping, the first linear moving component 4 is started, driving the entire clamping component 2 and the dust removal component 3 to move up and down, and the wheel 25 reduces friction.

[0040] The present invention discloses a dust removal device for electrical automation equipment, comprising a clamping component 2, a dust removal component 3, a first linear motion component 4, and a second linear motion component 5. The clamping component 2 drives a first clamping plate 21 and a second clamping plate 22 via an adjusting screw 24 to achieve adjustable spacing. A wheel assembly provided on the clamping side ensures a close fit between the device and the cabinet while also enabling smooth sliding. The first linear motion component 4 is vertically arranged and detachably connected, driving the entire device to move up and down along the sidewall of a control cabinet 1. The second linear motion component 5 is horizontally arranged and drives the dust removal component 3 to perform lateral cleaning, forming a three-dimensional cleaning network. Through a unique dual-axis coordinated motion mechanism and adaptive clamping design, the device achieves efficient dust removal without blind spots in the control cabinet 1. It boasts the advantages of easy installation, stable operation, and a wide range of applicability, making it particularly suitable for automated cleaning and maintenance of various electrical control cabinets 1. Its modular design also supports rapid switching between multiple operating modes, such as vacuuming and purging, and can be expanded with integrated intelligent sensors to achieve closed-loop control, significantly improving the efficiency and safety of dust removal operations for electrical equipment.

[0041] The embodiment of the present invention has two working modes. In mode 1, the first linear motion component 4 drives the clamping component 2 and the dust removal component 3 to continuously move up and down along the side wall of the control cabinet 1. At the same time, the second linear motion component 5 drives the dust removal component 3 to perform horizontal reciprocating cleaning, realizing the synchronous coordination of vertical and horizontal movements to form a continuous three-dimensional cleaning path.

[0042] Mode 2: The first linear moving component 4 is first fixed at a certain height. After the dust removal component 3 completes lateral cleaning at the current height, the first linear moving component 4 is unlocked and adjusted to the next target height. The dust removal component 3 performs lateral cleaning again, and this cycle continues until the entire counter surface is covered. Mode 1 is suitable for quick and comprehensive cleaning with higher efficiency. Mode 2 is suitable for deep cleaning of key areas and can increase the number of cleanings for heavily polluted areas. By switching modes, the embodiment of the present invention can flexibly adapt to different dust removal needs, taking into account both efficiency and precision.

[0043] Optional, reference Figure 3 and Figure 4 The first linear moving component 4 includes: a first guide rail 41, a first slider 42 and a plurality of permanent magnets 43. The first guide rail 41 is adsorbed on the side wall of the control cabinet 1 through the embedded permanent magnet 43. The first slider 42 is slidably connected to the first guide rail 41, and the first slider 42 is fixedly connected to the first clamping plate 21.

[0044] Specifically, the permanent magnet 43 is embedded in the side wall where the first guide rail 41 and the control cabinet 1 are in contact, and the first slider 42 is made of ceramic composite material.

[0045] In the embodiment of the present invention, the first linear moving component 4 adopts a permanent magnet 43 adsorption guide rail design. The first guide rail 41 is firmly adsorbed on the side wall of the control cabinet 1 by the high-performance NdFeB permanent magnets arranged in an array. The single-point adsorption force can reach more than 50N, which not only ensures the rapid installation of the device, but also achieves stable and reliable vertical fixation. The slider and the guide rail adopt a self-lubricating copper sleeve with a T-slot structural design, so that the device can move smoothly along the height direction of the cabinet during the dust removal process. Abandoning the traditional bolt fixing method, non-destructive installation is achieved through magnetic attraction. It is suitable for iron control cabinets 1 with smooth surfaces. While ensuring the load-bearing capacity, it avoids damage to the cabinet structure caused by drilling operations, and no traces are left after disassembly. The nickel-plated surface of the permanent magnet 43 and the magnetic steel plate optimize the magnetic circuit distribution, so that the magnetic force is concentrated on the side wall of the cabinet, effectively reducing the impact of magnetic leakage on peripheral equipment.

[0046] In the above-mentioned embodiment of the invention, the first guide rail 41 is fixed to the side wall of the control cabinet 1 by magnetic attraction. However, during the specific fixing process, there is a risk that the guide rail may tilt due to an uneven adsorption surface or installation deviation. This tilt will directly affect the vertical movement accuracy of the device, thereby reducing the dust removal effect. Therefore, the embodiment of the present invention provides an improved method.

[0047] Optional, reference Figure 3 The upper end of the first guide rail 41 is fixedly connected to a horizontal fixing plate 44 , and the fixing plate 44 is in contact with the upper wall of the control cabinet 1 .

[0048] The design of the additional horizontal fixing plate 44 at the upper end of the first guide rail 41 improves the overall stability of the device. The fixing plate 44 is rigidly connected to the first guide rail 41. The upper horizontal fixing plate 44 forms a right angle with the guide rail, which fits in with the corner of the top of the control cabinet 1. The lower part is initially fixed by a magnetic component, and the upper part is closely fitted with the horizontal fixing plate 44 and the upper wall of the cabinet to provide a reference correction. The two work together to ensure the vertical installation accuracy of the first guide rail 41. This improvement effectively eliminates the deflection problem caused by unilateral fixation, allowing the first linear moving component 4 to maintain a precise vertical motion trajectory, thereby ensuring that the dust removal component 3 completes the cleaning operation according to the predetermined path, significantly improving the dust removal effect and operation reliability. This dual positioning mechanism improves the device's ability to maintain position during long-term use, and is particularly suitable for stable dust removal operations in large control cabinets 1.

[0049] Optional, reference Figure 2 and Figure 3 The second linear moving component 5 includes: a second guide rail 51 and an annular slide 52. The first end of the second guide rail 51 is fixedly connected to the connecting plate 23, and the second end extends to the other side of the control cabinet 1. The second guide rail 51 is provided with a slide groove 511 on the upper and lower sides. The upper and lower inner walls of the annular slide 52 are fixedly connected with a second slider 521 matching the slide groove 511, and the slide groove 511 is connected to the second sliding.

[0050] The second linear motion component 5 utilizes an innovative annular slide 52 structure to achieve all-round horizontal cleaning coverage. This component comprises a second guide rail 51 and an annular slide 52. One end of the second guide rail 51 is fixedly connected to the connecting plate 23 of the clamping component 2, while the other end extends across the control cabinet 1 to the opposite side, forming a stable support structure. Precision slides 511 on the upper and lower sides of the guide rail form a double sliding pair with the sliders on the inner wall of the annular slide 52, ensuring smooth and wobbly operation. When the first linear motion component 4 drives the device to move vertically along the cabinet, the annular slide 52 can perform horizontal reciprocating motion along the second guide rail 51, driving the dust removal component 3 to complete the lateral cleaning action, and together with the vertical motion, form a three-dimensional cleaning network. Compared to traditional single-sided slider designs, the load capacity is increased while effectively preventing dust from entering the sliding surface. This structure adapts to the clamping component 2 and, while ensuring the device is firmly fixed, achieves continuous, no-dead-angle dust removal across the entire front area of ​​the control cabinet 1. It is particularly suitable for standard control cabinets 1, significantly improving cleaning efficiency and ease of operation.

[0051] Optional, reference Figure 3 The dust removal assembly includes a brush 31 and an air nozzle 32. The air nozzle 32 is fixedly connected to the annular slide 52, and the air nozzle 32 faces the inside of the control cabinet 1. The brush 31 is connected to the annular slide 52 through a connecting rod 33, and the brush 31 faces the inside of the control cabinet 1.

[0052] Specifically, the air nozzle 32 is connected to the high-pressure dust collection device through a hose to absorb the dust inside the control cabinet 1.

[0053] The air nozzle 32 is fixed to the annular slide 52 and faces the interior of the control cabinet 1, forming a "sweep first, then suck" operation mode with the brush 31: when the device is running, the brush 31 moves horizontally with the annular slide 52 via the connecting rod 33, sweeping away the dust attached to the surface of the components in the cabinet; at the same time, the air nozzle 32 immediately sucks the raised dust into the dust removal system to avoid secondary contamination. The dual functions of the brush 31 and the air nozzle 32 ensure that there is no dead angle cleaning in three-dimensional space. In particular, the brush 31 is made of anti-static nylon material, which can effectively remove stubborn dust without generating static electricity; the air nozzle 32 is connected to a high-pressure dust collection system with adjustable suction force, which can be flexibly adjusted according to the type of dust and the degree of accumulation. Compared with single vacuuming or blowing methods, this combined dust removal solution improves cleaning efficiency and is particularly suitable for the thorough removal of various types of dust in precision electrical equipment.

[0054] Optional, reference Figure 5 An elastic element 331 is connected between the brush 31 and the connecting rod 33 .

[0055] Specifically, the elastic element 331 is a stainless steel coil spring with an elastic coefficient of 50 N / mm.

[0056] The elastic element 331 can provide a constant contact pressure of 10-30N, allowing the brush 31 to effectively remove stubborn dirt without damaging delicate components. When encountering raised terminals or heat sinks inside the cabinet, the elastic contraction function ensures that the brush 31 can smoothly pass over the obstacle, avoiding jamming or component damage. This allows the brush 31 to adapt to minor unevenness on the cabinet surface, ensuring uniform cleaning across the entire work surface. When the brush 31 sweeps away dust, the elastic pressure ensures optimal cleaning contact force, while the air nozzle 32 efficiently absorbs dust within the optimal distance. This design improves dust removal efficiency and reduces equipment damage rates. It is particularly suitable for complex control cabinet environments with component height differences, such as mixed relays and terminal blocks, and also extends the service life of the brush 31.

[0057] Optional, reference Figure 5 , the connecting rod 33 is a telescopic rod.

[0058] Specifically, the connecting rod 33 is marked with scale.

[0059] The connecting rod 33 utilizes a telescopic design, significantly enhancing the flexibility and safety of dust removal operations through an innovative adaptive length mechanism. Made of anodized aluminum alloy, the telescopic rod features a quick-release locking mechanism. Using graduated markings on the rod, the operator can quickly and precisely adjust the depth of the brush 31 within the cabinet to prevent interference with internal components. In the event of unexpected resistance, such as an accidental collision with cables, the telescopic structure passively retracts to cushion the impact, effectively protecting the equipment. Together with the elastic element 331, this creates a dual protection system combining macro-length adjustment with micro-pressure adaptation. As the first linear motion component 4 drives the device vertically along the cabinet, the operator can adjust the length of the telescopic rod in real time based on the distribution of components at different heights, ensuring that the brush 31 always maintains its optimal working position. Simultaneously, as the second linear motion component 5 drives the annular slide 52 horizontally, the rigid locking mechanism of the telescopic rod ensures a stable trajectory for the brush 31. This design expands the scope of dust removal operations and reduces the risk of accidental equipment collisions. Furthermore, by optimizing the working distance of the brush 31, the dust collection efficiency of the air nozzle 32 is significantly improved.

[0060] Optional, reference Figure 1 There are two adjusting screws 24, which are arranged vertically and in parallel, and one end of the adjusting screw 24 has an adjusting handle.

[0061] Specifically, there are anti-slip textures on the adjustment handle.

[0062] The adjustment mechanism of the clamping component 2 utilizes a twin-screw synchronous drive design, with two vertically parallel adjustment screws 24. Each screw is equipped with an adjustment handle with anti-slip ridges at the top. The twin-screw structure distributes the clamping force more evenly, effectively preventing cabinet deformation caused by unilateral clamping. The anti-slip handle design ensures sufficient operating torque even in wet or oily environments.

[0063] A dust removal method for a dust removal device of an electrical automation equipment comprises the following steps:

[0064] S1: Slidingly connect the clamping component 2 to the side wall of the control cabinet 1 through the adjusting screw 24 of the clamping component 2;

[0065] S2: Start the first linear moving component 4 to drive the clamping component 2 and the dust removal component 3 to move up and down at a constant speed along the side wall of the control cabinet 1;

[0066] S3: Synchronously start the second linear moving component 5 to drive the dust removal component 3 to perform horizontal reciprocating cleaning motion;

[0067] S4: until the dust removal component 3 cleans and covers the entire cabinet surface.

[0068] Optionally, the following alternative implementations are also included:

[0069] S21: Locking the first linear moving component 4 at an initial height position;

[0070] S22: Start the second linear moving component 5 to enable the dust removal component 3 to complete the horizontal cleaning of the current height layer;

[0071] S23: The first linear moving component 4 is unlocked, adjusted to the next target height, and then re-fixed;

[0072] S24: Repeat steps S22-S23 until the entire counter surface is cleaned in layers;

[0073] S25: For key pollution areas, increase the cleaning frequency at this height.

[0074] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
