Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a dust removal device for electromechanical equipment. Background Technology

[0002] In modern industrial production, electromechanical equipment is widely used in various fields, such as manufacturing, mining, and the power industry. However, these devices inevitably face the problem of dust pollution during operation. Dust not only affects the normal operation of electromechanical equipment and reduces its efficiency, but may also lead to equipment failure, shorten its service life, and increase maintenance costs.

[0003] For example, when using dust removal equipment to remove dust from transformer cabinets in electromechanical equipment, the operator usually needs to insert the vacuum cleaner nozzle into the inside of the transformer cabinet. With the powerful suction of the vacuum cleaner, most of the dust accumulated on the inner surface of the transformer cabinet is removed. However, for some stubborn dust attached to the gaps and corners of transformer cabinet components, it is often difficult to completely remove it by vacuum cleaner alone. At this time, it is necessary to use a brush for further cleaning to achieve a comprehensive and thorough dust removal effect. However, manual dust removal will result in a slower dust removal speed and poor dust removal effect.

[0004] Furthermore, staff cannot automatically adjust the cleaning intensity based on the actual amount of dust in the transformer cabinet. This is because the dust particles inside the transformer cabinet vary in size, ranging from tiny inhalable particles to larger dust particles. As a result, there will be dust that is difficult for workers to observe, making it difficult to automatically control the cleaning intensity according to the actual situation. Therefore, if there is a lot of dust inside the transformer cabinet and the cleaning intensity is not increased accordingly, some dust will not be completely removed. Conversely, if there is a small amount of dust in the transformer cabinet, but a large cleaning intensity is still applied, it may cause unnecessary wear and tear on the sensitive components inside the transformer cabinet. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a dust removal device for electromechanical equipment. This device effectively solves the problem of the cumbersome process of manually cleaning the inside of transformer cabinets using vacuum cleaners and brushes, which requires deep inside the cabinet. Furthermore, due to the diverse particle sizes of dust inside the transformer cabinet and the difficulty in observing some particles, it is difficult for staff to automatically adjust the cleaning intensity based on the actual amount of dust, which can easily lead to insufficient cleaning or excessive wear on parts.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] 1. The amount of dust in the transformer cabinet is detected by a metal oxide semiconductor chip and a current detector in the dust detection mechanism. Dust particles adhering to the surface of the metal oxide semiconductor chip will reduce the carrier mobility and the current. The current detector transmits the detected current to the PLC controller through an electrical signal. The PLC controller determines the amount of dust based on the electrical signal and then adaptively adjusts the cleaning process. It can automatically adjust the cleaning intensity and other operations according to the actual amount of dust in the transformer cabinet, so as to avoid the equipment being affected by improper cleaning intensity.

[0021] 2. This device includes a dust collector for dust extraction, a sweeping roller for dust removal, and a wiping sponge for wiping. A powerful fan blows dust off the transformer, the sweeping roller cleans dust adhering to the inner wall of the transformer cabinet, the dust collector collects the swept dust, and the wiping sponge further cleans the areas where dust has been extracted. In addition, water spraying from the spray nozzle and scraping from the inclined scraper can assist in cleaning the wiping sponge, ensuring its cleaning effect. This achieves comprehensive cleaning of the transformer cabinet. By comprehensively utilizing multiple cleaning methods, it can effectively remove dust from all locations inside the transformer cabinet, including stubborn dust, resulting in a more thorough and cleaner cleaning compared to traditional methods.

[0022] 3. By coordinating the operation of the first, second, third, and fourth motors, as well as the electric telescopic rod, within the adjustment mechanism, the position and angle of the dust removal mechanism are automatically controlled, enabling it to penetrate deep into various locations inside the transformer cabinet for cleaning. For example, the fourth motor drives the electric telescopic rod to rotate and extend into the transformer cabinet, while the first motor drives the first threaded rod to rotate, causing the dust removal mechanism to move up and down. When the ultrasonic distance detector detects a distance of 5 centimeters from the inner wall of the transformer cabinet, the motor is automatically stopped, achieving precise positioning. This eliminates the need for manual cleaning with hand tools, automatically completing the dust removal operation inside the transformer cabinet, significantly improving dust removal efficiency and reducing labor costs and intensity.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Example: Refer to Figures 1 to 8 A dust removal device for electromechanical equipment, comprising:

[0036] The support plate 1 is fixedly connected to the top of the support plate 1. The outer wall of the support plate 2 is fixedly connected to the baffle 3. The baffle 3 is fixedly connected to the bottom of the baffle 3. After the blower 4 blows fresh air to the bottom of the transformer cabinet, the air at the bottom will rise as the air volume increases. The cabinet door is usually located on the side or top of the transformer cabinet, which is a relatively easy channel for air to flow out. After the air rises to a certain height inside the transformer cabinet, it will naturally flow towards the cabinet door, and then carry the dust out from the cabinet door.

[0037] The dust detection mechanism 5 includes a metal oxide semiconductor chip 51 fixedly connected to the top of the baffle 3. The metal oxide semiconductor chip 51 is electrically connected to a current detector 52 to form a detection circuit. The current detector 52 is electrically connected to a PLC controller.

[0038] Dust particles adhering to the surface of the metal oxide semiconductor wafer 51 roughen its surface, disrupting its smoothness and periodicity. When charge carriers move within the wafer 51, they are scattered by these dust particles and the surface irregularities caused by the dust, increasing the scattering probability and reducing carrier mobility. According to semiconductor conductivity theory, current is directly proportional to carrier mobility; a decrease in mobility results in a decrease in current. Therefore, the more dust present, the lower the current flowing through the metal oxide semiconductor wafer 51. Multiple experimental tests showed that when the amount of dust adhering to the surface of the metal oxide semiconductor wafer 51 reached 0.1 mg / cm³, the current was significantly reduced. 2 At that time, its current decreased by 10% compared to the initial state; when the dust content reached 0.3 mg / cm³ 2 When the current drops by 30%, the PLC controller determines the degree of dust contamination in the transformer cabinet based on the pre-set correspondence between the current drop ratio and the amount of dust. For example, a current drop of 10-20% indicates light contamination, 20-40% indicates moderate contamination, and more than 40% indicates heavy contamination. The controller then adaptively adjusts the cleaning process accordingly.

[0039] The dust removal mechanism 6 includes a dust collector 61 for dust extraction, a cleaning roller 62 for dust sweeping, and a wiping sponge 63 for wiping.

The rotation speed of the cleaning roller 62 is set to 150 revolutions per minute, which can ensure efficient cleaning of the dust on the inner wall of the transformer cabinet. The wiping sponge 63 is a high-density absorbent sponge, which can absorb 3 times its own weight in water when saturated, ensuring a good cleaning effect during wiping.

[0040] The dust removal mechanism 6 includes a connecting plate 69 fixedly connected to the outer wall of the telescopic end of the electric telescopic rod 712.

The ultrasonic distance detector 610, the first motor 72, the second motor 76 are electrically connected to the PLC controller to form a processing circuit. The distance between the ultrasonic distance detector 610 and the wiping sponge 63 can be determined through pre-testing (assumed to be 5 cm).

[0041] The cleaning assembly 68 includes a water pump 681 and a drain pump 682 fixedly connected to the outer wall of the cleaning hood 65 on the side away from the exhaust hood 64. A water spray head 683 is fixedly connected to the inner wall of the cleaning hood 65. The outlet end of the drain pump 682 is connected to the water spray head 683.

[0044] A water tank 623 is fixedly connected to the top of the support plate 1. A water filter is installed inside the water tank 623. The water tank 623 is filled with clean water. A first water pump 624 and a second water pump 625 are fixedly connected to the top of the regulating shell 75.

The cleaning roller 62 and the wiping sponge 63 are at the same level, so both of them are in contact with the inner wall of the transformer cabinet at the same time.

[0047] The support plate 1 is equipped with a pusher, and a movable structure (existing technology) that can be fixed and moved is provided below the support plate 1. When it is necessary to move the device, it can be switched to the movable mode, and after moving to the designated position, it can be switched to the fixed mode.

[0048] The working principle of this utility model is as follows:

[0049] First, open the transformer cabinet door. Then, move the device to the transformer cabinet that needs cleaning, blocking the cabinet opening with the baffle 3. Next, start the blower 4 to blow fresh air into the bottom of the transformer cabinet, causing the dust inside to float. The airflow causes the dust to drift outwards from the cabinet opening. As it reaches the opening, it contacts the metal oxide semiconductor chip 51, altering the current in the chip. The current detector 52 detects the current passing through the metal oxide semiconductor chip 51 and transmits the current signal to the PLC controller. For example, a higher current through the metal oxide semiconductor chip 51 indicates more dust inside the transformer cabinet. Therefore, the cleaning process can be adaptively adjusted based on the actual detection results. The specific cleaning process is as follows:

[0050] First, the fourth motor 711 is started, driving the electric telescopic rod 712 to rotate 90 degrees, allowing it to extend into the transformer cabinet. Then, the first motor 72 is started, driving the first threaded rod 73 to rotate. Due to the limiting effect of the sliding groove 71 on the threaded block 74, the threaded block 74 moves up and down, thereby moving the dust removal mechanism 6. The dust removal mechanism 6 is first moved to the bottom or side wall of the transformer cabinet. Then, the PLC controller automatically stops either the first motor 72 or the second motor 76 (the driving method of the second motor 76 is the same as that of the first motor 72, and will not be described in detail here). The specific steps are as follows:

[0051] When the ultrasonic distance detector 610 detects a distance of 5 cm from the inner wall of the transformer cabinet, it immediately sends an electrical signal to the PLC controller, which then controls the first motor 72 or the second motor 76 to stop.

[0052] Then start the multi-stage electric telescopic rod 712, water pump 681, drainage pump 682, dual-port exhaust pump 613, air pump 630, first water pump 624, second water pump 625, powerful fan 627, fifth motor 629, and dust collector 61.

[0053] The dust removal mechanism 6 is moved forward by the multi-stage electric telescopic rod 712, and the airflow is blown out to the transformer inside the transformer cabinet by the powerful fan 627, thereby blowing off the dust on the transformer. The cleaning roller 62 is driven to rotate by the fifth motor 629, and the cleaning roller 62 cleans the dust attached to the inner wall of the transformer cabinet. At the same time, the dust collector 61 collects the cleaned dust.

[0054] The collected dust is discharged into the drive housing 66, and then the wind blows the impeller 67 to rotate. The impeller 67 drives the rotating rod and the wiping sponge 63 to rotate. The rotation of the wiping sponge 63 can further clean the area where the dust was extracted. Then the extracted dust is extracted by the dual-port exhaust pump 613 and discharged into the air connection ring 616. The dust is then transferred to the air connection ring 616 and then the exhaust pump 630 extracts the dust from the air connection ring 616 and discharges it into the impurity collection box 617.

[0055] During the rotation of the wiping sponge 63, the first water pump 624 draws clean water from the water tank 623 and discharges it into the water inlet chamber 619. Then, the drain pump 682 draws clean water from the water inlet chamber 619 and discharges it into the spray head 683. The spray head 683 sprays clean water onto the wiping sponge 63, and then the inclined scraper 684 on the lower side scrapes the wiping sponge 63, thereby scraping off the impurities on the wiping sponge 63. Then, the water pump 681 draws out the mixture of scraped impurities and sewage and discharges it into the water outlet chamber 620. Then, the second water pump 625 draws out the sewage from the water outlet chamber 620 and discharges it into the water filter in the water tank 623 for filtration, thereby achieving water recycling. The water that is not cleaned off on the wiping sponge 63 can be used to assist the wiping sponge 63 in cleaning the inner wall of the transformer cabinet.

[0056] Each time the transformer is moved from one end to the other, a powerful blower 627 is used to clean the innermost wall of the transformer. Although the air cleaning is not as thorough as the cleaning described above, the cleaning effect will still be as expected. There may be wire harnesses inside the transformer cabinet. When encountering wire harnesses, manual control is required to bypass the wire harness connection and use air cleaning to prevent damage to the wire harnesses. Alternatively, a test can be performed in advance and the data can be input into the PLC controller for automatic control (manual control is still the best option).

[0057] After one side of the inner wall is treated, the wiping sponge 63 and the cleaning roller 62 need to be separated from the inner wall of the transformer cabinet. Then, the third motor 79 is started (the third motor 79 is pre-set to drive at a 90-degree angle each time). The third motor 79 drives the adjusting frame 710 to rotate, which in turn drives the electric telescopic rod 712 to rotate 90 degrees, so that the dust removal mechanism 6 faces the inner wall of the transformer on the other side, thereby cleaning the inner wall there.
