[0042] A dust removal device for power system automation equipment, comprising:

[0043] A transparent dust collecting cover 1 is provided with a magnetic attraction ring 11 at the edge thereof, which has the same shape as the opening of the cover and is used for adsorption fixation;

[0044] A circulating air pressure mechanism 2 is arranged at the back of the transparent dust collecting cover 1 and is used for extracting the air inside the cover and performing circulating pressurization; and

[0045] A high-pressure dust blowing mechanism 3 is arranged at both sides of the transparent dust collecting cover 1 and is connected with the high-pressure gas output end of the circulating air pressure mechanism 2 in a through manner;

[0046] The circulating air pressure mechanism 2 is used for performing high-pressure gas blowing and dust removal on the inside of the power equipment by extracting the air inside the transparent dust collecting cover 1 in a circulating manner, pressurizing and then delivering to the high-pressure dust blowing mechanism 3;

[0047] In actual installation, it is necessary to pay attention to the fact that the opening shape of the transparent dust collecting cover 1 must be completely matched with the profile of the area to be dusted of the power equipment, so as to ensure that the magnetic attraction ring 11 can be closely attached to the surface of the equipment. If the surface of the equipment is a curved surface or a special-shaped structure, the magnetic attraction ring 11 should be made of flexible material and be internally provided with multiple independent magnetic blocks, so as to adapt to different radii. Before installation, the surface of the equipment should be cleaned to avoid that oil stains or rust marks affect the magnetic attraction effect. During operation, the edge of the dust collecting cover should be pressed by hand first to preliminarily attract, and then gradually compacted along the periphery to ensure that there is no air leakage gap. For large equipment, it is recommended that two persons cooperate to operate to avoid that the dust collecting cover is sagged due to gravity and causes the sealing to be not tight. The transparency of the dust collecting cover should be kept above 90% to facilitate the observation of the internal dust removal condition, and the material is recommended to be selected as anti-static PC plastic with a thickness not less than 3 mm to prevent deformation caused by high-pressure airflow impact.

[0048] Further, the circulating air pressure mechanism 2 comprises:

[0049] A gas circulating assembly 21 comprises an air pressure bin 211 arranged at the back of the transparent dust collecting cover 1, an air extraction port 212 for extracting gas which is opened at one side inside the cover 1, and a high-pressure gas outlet pipe 213 which is arranged outside the cover 1 and is connected with the air pressure bin 211 in a through manner along the tangent line of the bin 211;

[0050] a driving assembly 22, which comprises a driving motor 221 arranged outside the air compression chamber 211 and a turbine 222 mounted on the power output end of the driving motor 221 and arranged inside the air compression chamber 211;

[0051] The driving motor 221 drives the turbine 222 to rotate inside the air compression chamber 211, so that the air inside the transparent dust collecting cover 1 can be extracted through the air suction port 212 and then pressurized and delivered into the high-pressure air outlet pipe 213;

[0052] The driving motor 221 of the circulating air compression mechanism 2 is preferably a brushless direct current motor with a power of not less than 200W, so as to ensure that the turbine 222 can maintain a rotation speed of more than 3000r / min. The inner wall of the air compression chamber 211 needs to be polished to reduce air flow friction loss. The ratio of the diameter of the air suction port 212 to the cross-sectional area of the high-pressure air outlet pipe 213 should be controlled at 1:1.5 to avoid dust deposition caused by sudden drop of air flow speed. In actual operation, the driving motor 221 should be started to idle for 30 seconds first, and then the transparent dust collecting cover 1 is buckled onto the equipment after the turbine 222 reaches the rated speed. It should be particularly noted that the tangent connection angle of the high-pressure air outlet pipe 213 should be accurately 45°, which can utilize the Coanda effect to increase the air flow speed by more than 15%. The turbine 222 blades should be checked regularly for dust agglomeration, and it is recommended to be cleaned once a month by an ultrasonic cleaner to prevent dynamic balance failure.

[0053] Further, the high-pressure dust blowing mechanism 3 comprises:

[0054] a universal dust blowing assembly 31, which comprises a gas conveying hose 311 connected with the high-pressure air outlet pipe 213, a high-pressure dust blowing gun 312 arranged at the other end of the gas conveying hose 311 for handheld dust blowing, and a sealing rubber sleeve 313 fixedly installed on both sides of the transparent dust collecting cover 1 for fixing the high-pressure dust blowing gun 312;

[0055] The sealing rubber sleeve 313 is used to seal between the transparent dust collecting cover 1 and the high-pressure dust blowing gun 312 and keep the high-pressure dust blowing gun 312 rotating in all directions;

[0056] The gas delivery hose 311 of the high-pressure dust blowing mechanism 3 should adopt a four-layer steel wire braided structure, and the pressure resistance value should reach more than 1 MPa. The nozzle aperture of the high-pressure dust blowing gun 312 should be set to 2 mm, and a copper anti-static sleeve should be installed at the front end to avoid sparks generated by high-pressure airflow. The Shore hardness of the sealing rubber sleeve 313 should be controlled at 60±5 degrees. If it is too soft, the gun body will shake and leak, and if it is too hard, it will affect the flexibility of the universal adjustment. When operating, the operator should use both hands: one hand holds the base of the gun body, and the other hand adjusts the nozzle angle. The dust blowing time at each place should not exceed 5 seconds to prevent local overheating. The dust blowing sequence should follow the principle of "from inside to outside, from top to bottom". For precision components, a safety distance of more than 30 cm should be maintained. The connection between the sealing rubber sleeve 313 and the transparent dust collector 1 should be coated with silicone every quarter to prevent rubber aging and cracking.

[0057] Further, the mounting mechanism 4 includes a mounting rack 41 adapted to the shape of the transparent dust collector 1 and a fixing assembly 42 arranged at the top and bottom of the mounting rack 41.

[0058] The transparent dust collector 1 is fixed by the magnetic attraction ring 11 on one side of the mounting rack 41, and the mounting rack 41 is fixed and installed on the power equipment by the fixing assembly 42.

[0059] Further, the fixing assembly 42 includes:

[0060] The elastic support unit 421 includes a clamping rod 4211 movably inserted into the top and bottom of the mounting rack 41, a resistance spring 4212 arranged between the two clamping rods 4211 for pushing them outward, and a pad 4213 arranged at the other end of the clamping rod 4211 for increasing the friction between the clamping rod 4211 and the inner wall of the power equipment;

[0061] The manual reset unit 422 includes a sliding groove 4221 opened at the top and bottom of the mounting rack 41, and a handle 4222 connected above the clamping rod 4211 and capable of sliding the clamping rod 4211 in the sliding groove 4221;

[0062] The clamping rod 4211 of the mounting mechanism 4 is preferably made of 304 stainless steel and has an anti-slip knurling treatment on the surface. The extension stroke should be no less than 50 mm to adapt to different equipment thicknesses. The elastic coefficient of the resistance spring 4212 needs to be calculated according to the weight of the equipment. Generally, 0.5 N / mm of spring is used for every kilogram. During installation, first push the handle 4222 inward to the limit position, so that the pad 4213 is completely retracted. After the mounting frame 41 is placed into the equipment frame, slowly release the handle 4222. At this time, the spring force will press the pad 4213 tightly against the inner wall of the equipment. For environments with strong vibration, damping grease should be added to the sliding groove 4221 to prevent the clamping rod 4211 from moving spontaneously. The polyurethane wear-resistant layer of the pad 4213 should be checked regularly. When the wear exceeds 2 mm, it should be replaced immediately to avoid a decrease in the fixing force.

[0063] Further, it further comprises:

[0064] The sealing mechanism 5 comprises a plastic film 51 connected to the outer wall of the transparent dust cover 1 for sealing and a magnetic strip 52 arranged at the edge of the plastic film 51 for being attracted and fixed to the power equipment by magnetic force.

[0065] The magnetic strip 52 is used to block the gap between the transparent dust cover 1 and the power equipment by attracting the edge of the plastic film 51 to the power equipment.

[0066] The plastic film 51 of the sealing mechanism 5 should be made of a 0.15 mm thick PET composite film with an elongation greater than 300% to adapt to different gap widths. The magnetic flux of the magnetic strip 52 should not be less than 3000 Gauss, and a magnetic pole unit should be arranged every 10 cm. In actual operation, the plastic film 51 should be unfolded to cover the gap, and then the magnetic strip 52 should be gradually attracted and fixed from one end. Special attention should be paid to cutting a triangular gap in the film in advance at the corner to prevent wrinkles and air leakage. For gaps wider than 5 mm, a laminated sealing method should be used: first stick a layer of film, then stack a second layer in parallel, and the magnetic strips 52 of the two layers are arranged in staggered positions. The plastic film 51 should be stored with alcohol after use to avoid dust attachment affecting the sealing effect next time.

[0067] Further, it further comprises:

[0068] The filtering mechanism 6 comprises a filtering housing 61 screw-connected between the high-pressure gas outlet pipe 213 and the gas conveying hose 311 and a conical filter screen 62 arranged inside the filtering housing 61 for filtering the gas extracted from the transparent dust cover 1.

[0069] The cone-shaped filter screen 62 of the filter mechanism 6 is recommended to be made of pleated non-woven fabric with a filtration accuracy of 20μm and a cone angle of 60° to increase the effective filtration area. A copper gasket should be installed at the threaded connection of the filter housing 61 to ensure a tight seal. When the differential pressure gauge shows an inlet / outlet pressure difference exceeding 0.05MPa, the machine must be stopped immediately and the filter screen replaced. When cleaning the filter screen, a reverse pulse airflow should be used for blowing; water rinsing is prohibited to prevent clogging of the mesh. For oily and dusty environments, a layer of activated carbon fiber felt with a basis weight of not less than 200g / m² should be pre-laid inside the filter housing 61. Special attention should be paid to ensuring that the filter mechanism 6 is installed on the straight section of the air supply hose 311 to avoid turbulence at bends that could cause secondary dust generation.

[0070] In summary, the dust removal device for power system automation equipment provided by this utility model, during operation, firstly, aligns the mounting bracket 41 with the area of ​​the power equipment to be dusted, and pushes the lever 4211 inward with the handle 4222 to compress the resistance spring 4212. After the mounting bracket 41 is placed in the equipment frame, slowly release the handle 4222, so that the pad 4213 is firmly fixed against the inner wall of the equipment under the action of the spring force. After the mounting bracket 41 is fixed, align the magnetic adsorption ring 11 of the transparent dust collection cover 1 with the edge of the mounting bracket 41, and press it with your hand to adsorb and fix it, ensuring that the dust collection cover is tightly attached to the surface of the equipment without gaps. For larger gaps at the edge of the equipment, unfold the plastic film 51 to cover the gap area, and use the magnetic strip 52 to gradually adsorb and fix it from one end. Triangular notches are pre-cut at the corners to prevent wrinkles. If the gap width exceeds 5mm, a layered sealing method is used to stack two layers of film in parallel, and the magnetic strips 52 are arranged in a staggered manner to enhance the sealing effect.

[0071] Then, start the drive motor 221 and let it idle for ten seconds. After the turbine 222 reaches its rated speed, the operator holds the high-pressure dust guns 312 on both sides of the transparent dust collection hood 1. The air supply hose 311 is sealed by the sealing rubber sleeve 313. When blowing dust, hold the base of the gun body and adjust the nozzle angle by rotating the base of the gun body. Blow the inside of the equipment in the order from the inside to the outside and from top to bottom. The blowing time for each part should be controlled within 5 seconds, and a distance of more than 30cm should be maintained from the precision components.

[0072] The circulating air compressor 2 draws dust-laden air from the transparent dust collection hood 1 through the air intake port 212. The turbine 222 rotates and pressurizes the air within the air compressor chamber 211, and the airflow enters the high-pressure outlet pipe 213 tangentially. The high-pressure gas is filtered by the conical filter screen 62 inside the filter housing 61 and then re-delivered to the high-pressure dust blower 312 through the air delivery hose 311, forming a circulating airflow. The filter mechanism 6 intercepts dust particles; when the pressure difference exceeds 0.05 MPa, the machine must be stopped and the filter screen replaced.
