Description

Technical Field

[0001] The invention relates to the technical field of power supply equipment, in particular to a dual-power supply power supply equipment for a coal mill oil station. Background Art

[0002] During the operation of the coal mill oil station, power distribution boxes and other power supply equipment are required to provide a stable power supply to ensure the normal operation of the coal mill. Since the working environment of the coal mill oil station is usually more complex and the demand for electricity is high, a single power supply often cannot meet the requirements of stability and reliability. Therefore, the existing power supply equipment will use dual power supplies. Through the automatic converter, when the main power supply fails and cannot supply power normally, it will automatically switch to the auxiliary power supply to ensure the continuous and stable operation of the coal mill oil station and prevent production losses and equipment damage caused by power outages.

[0003] For example, in the prior art, the invention patent with the authorization announcement number CN117317848B discloses a dual power supply equipment box, which specifically relates to the field of power supply equipment, including a power box, a power module 1 and a power module 2 arranged in the power box, and a fixing mechanism for installing the power module 1 and the power module 2; the fixing mechanism includes a base body arranged in the power box, two sets of fixing claws arranged in the base body, two pressure seats arranged in the base body and connected to a set of fixing claws on the sides, a sliding gear rod arranged at the bottom of each pressure seat, a compression spring sleeved on the top of each sliding gear rod, and a rotating clamp arranged on both sides of the base body for driving the sliding gear rod. The above device can realize the convenient assembly, maintenance and replacement of the power module 1 and the power module 2 through the design of the fixing mechanism, without the need to configure an additional maintenance frame, which can conveniently meet the maintenance and use of maintenance personnel and improve maintenance efficiency; at the same time, when there is an abnormality, an alarm can be issued in time so that the inspection personnel can take timely solutions, thereby ensuring the working reliability of the equipment box.

[0004] Although the dual power supply equipment box in the above patent can facilitate maintenance and provide alarms, the existing dual power supply equipment has certain defects when used; during long-term use, the existing dual power supply equipment needs to use perfluorohexanone and other cleaning agents to clean the components in the power supply equipment under power on condition to remove external dust and ensure the normal electrical performance of the equipment. However, during the cleaning process, since the coal mill oil station needs to keep running at all times to reduce the downtime of the equipment and the impact on production, the staff needs to clean the inside of the power supply equipment during its operation. This practice poses a great safety hazard to the staff. During the cleaning process, the staff is directly exposed to the high voltage environment, and electric shock accidents may occur if they are not careful, posing a serious threat to the personal safety of the staff.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figures 1 to 12 A power supply device for a coal mill oil station with dual power supply comprises a power supply box 1 and a box door 2 connected to the power supply box 1. A threaded rod 3 and a sliding rod 4 are rotatably connected inside the box door 2. The threaded rod 3 and the sliding rod 4 are symmetrically located. A rotating assembly is connected to the bottom of the inner side of the box door 2. A moving rod 5 is threadedly connected to the outer wall of the threaded rod 3. The other end of the moving rod 5 is slidably connected to the sliding rod 4. An installation groove 12 is provided on the side of the moving rod 5 close to the power supply box 1. A connecting rod 13 is fixedly connected in the installation groove 12. A connecting rod 13 is provided in the connecting rod 13. There is a liquid guide groove 14, and a plurality of nozzles 15 connected to the liquid guide groove 14 are provided on one side of the connecting rod 13 close to the power supply box 1. A liquid guide tube 16 is connected to one end of the connecting rod 13. A booster pump 17 and a liquid storage box 18 are fixedly connected to the bottom surface of the power supply box 1. The booster pump 17 and the liquid storage box 18 are connected through a liquid outlet pipe 19. The liquid guide tube 16 is connected to the booster pump 17. A winding assembly is connected to the inner wall of the power supply box 1, a dust collecting assembly is connected to the bottom surface of the power supply box 1, and a sealing cover 20 is threadedly connected to the surface of the liquid storage box 18.

[0036] In the dual-power supply power supply equipment for coal mill oil station of the present invention, the liquid storage box 18 is filled with cleaning agents such as perfluorohexanone; after the power supply box 1 has been running for a period of time, dust will adhere to the surfaces of the components in the power supply box 1. At this time, the booster pump 17 is started to extract the cleaning agent such as perfluorohexanone from the liquid storage box 18, and then transport it to the liquid guide groove 14 through the liquid guide tube 16, and spray it out from the nozzle 15. At this time, the rotating component will drive the threaded rod 3 to rotate. Since the moving rod 5 is threadedly connected to the threaded rod 3 and the other end is slidably connected to the sliding rod 4, the moving rod 5 will move up and down along the axial direction of the threaded rod 3, so that the connecting rod 13 and the nozzle 15 thereon can cover different areas inside the power supply box 1, so as to completely clean the inside of the power supply box 1; at the same time, when encountering special circumstances such as internal fire, the booster pump 17 and the rotating component can be automatically started through the sensor inside the power supply box 1, so as to realize rapid processing of the fire area and prevent excessive losses; through the threaded rod 3 and the moving rod 5, etc. An automated cleaning method is presented, which avoids the risk of workers directly performing cleaning operations in a high-voltage electrical environment, greatly improving the personal safety of workers. The design of the rotating component enables the cleaning agent to quickly cover all components inside the power supply box 1, improving the cleaning efficiency and quality. At the same time, since the cleaning process can be carried out during the operation of the power supply equipment, there is no need to shut down or interrupt production, thereby reducing the downtime of the equipment and the impact on production. Regular cleaning can remove dust and dirt inside the power supply equipment and maintain the normal operation of its electrical performance, thereby extending the service life of the equipment and improving the reliability of the equipment; on the other hand, when encountering special circumstances such as internal fires, the sprayed cleaning agent can also quickly deal with the fire to avoid losses caused by the expansion of the fire. The cleaning and fire handling processes can be carried out or completed automatically during the operation of the power supply equipment, reducing the downtime of the equipment and the impact on production, and effectively reducing the safety risks of workers in emergency situations such as cleaning and fire.

[0037] As a preferred technical solution of the present invention, the rotating assembly includes a fixed block 6, a motor 9, a main gear 10 and a slave gear 11. The fixed block 6 is fixedly connected to the bottom of the box door 2. A power chamber 7 is provided in the fixed block 6. The motor 9 is fixedly connected to the power chamber 7. The output end of the motor 9 is fixedly connected to the main gear 10. A driving groove 8 corresponding to the position of the main gear 10 is provided in the fixed block 6. One end of the threaded rod 3 penetrates into the driving groove 8 and is fixedly connected to the slave gear 11. The main gear 10 is meshed with the slave gear 11.

[0038] Specifically, when the motor 9 is started, it drives the main gear 10 to rotate. Since the main gear 10 is meshed with the slave gear 11, the slave gear 11 will also rotate. The rotation of the slave gear 11 drives the rotation of the threaded rod 3. Since the moving rod 5 is threadedly connected to the threaded rod 3 and the other end is slidably connected to the sliding rod 4, the moving rod 5 will move up and down along the axial direction of the threaded rod 3. This movement process drives the connecting rod 13 and the nozzle 15 to move up and down, thereby achieving a comprehensive cleaning of the inside of the power supply box 1.

[0039] As a preferred technical solution of the present invention, the winding assembly includes a fixed plate 21, a winding shaft 22 and a coil spring 24. Two fixed plates 21 are fixedly connected to the inner wall of the power supply box 1, and the winding shaft 22 is rotatably connected between the two fixed plates 21. The middle part of the liquid guide tube 16 is wound around the outer wall of the winding shaft 22. A winding groove 23 is opened in a fixed plate 21, and a coil spring 24 is fixedly connected in the winding groove 23. The middle part of the coil spring 24 is fixedly connected to the winding shaft 22.

[0040] Specifically, as the threaded rod 3 drives the moving rod 5 to rise and fall, the winding shaft 22 and the coil spring 24 can ensure that the upper end of the liquid guide tube 16 is stretched straight, and the end of the liquid guide tube 16 connected to the booster pump 17 will fall on the bottom surface of the power supply box, thereby preventing the liquid guide tube 16 from contacting other electrical components or buttons in the power supply box 1 when the moving rod 5 stretches the liquid guide tube 16, thereby affecting the normal operation of the power supply box 1; at the same time, the liquid guide tube 16 can be automatically wound up or released as the moving rod 5 moves up and down, thereby preventing the liquid guide tube 16 from bending in the middle and affecting the circulation of the cleaning agent.

[0041] As a preferred technical solution of the present invention, the dust collecting component includes a dust box 29, a rotating shaft 30, a conveyor belt 31 and a dust scraping brush 35. The dust box 29 is fixedly connected to the bottom surface of the power supply box 1, and both ends of the dust box 29 are rotatably connected to the rotating shaft 30. The outer walls of the two rotating shafts 30 are sleeved with conveyor belts 31. A dust collecting cavity 34 is opened at the end of the dust box 29 away from the winding shaft 22, and a dust scraping brush 35 is fixedly connected in the dust collecting cavity 34. The dust scraping brush 35 is in contact with the bottom surface of the conveyor belt 31. One end of the dust box 29 is connected to a driving component, and the other end is connected to a sealing component.

[0042] Specifically, when cleaning agents such as perfluorohexanone are used to clean the power supply box 1, the cleaning agent will be effectively sprayed to every corner, washing away dust, dirt and other impurities from electrical components and the box wall, and falling on the conveyor belt 31. At this time, the drive assembly starts to work, providing power to the rotating shaft 30 to rotate. As the rotating shaft 30 rotates, the conveyor belt 31 also starts to move, transporting the dust and dirt that fall on it toward the dust collecting chamber 34. When the conveyor belt 31 transports the dust and dirt to the vicinity of the dust collecting chamber 34, the dust scraping brush 35 starts to work. The dust scraping brush 35 fits tightly with the bottom surface of the conveyor belt 31, and can effectively scrape off the dust and dirt remaining on the conveyor belt 31. The scraped dust and dirt then fall into the dust collecting chamber 34, realizing the collection of dust and avoiding dust and dirt staying in the power supply box 1 to cause secondary pollution.

[0043] As a preferred technical solution of the present invention, the driving assembly includes a driven wheel 32, a transmission belt 33 and a driving wheel 42. The driving wheel 42 is fixedly connected to one end of the winding shaft 22, and the driven wheel 32 is fixedly connected to one end of the rotating shaft 30 close to the winding shaft 22. A transmission belt 33 is connected between the driving wheel 42 and the driven wheel 32.

[0044] Specifically, when the threaded rod 3 drives the moving rod 5 to rise, it will pull the liquid guide tube 16, and the winding shaft 22 will rotate at this time, thereby driving the driving wheel 42 to rotate, and then driving the driven wheel 32 and the rotating shaft 30 to rotate through the transmission belt 33, realizing the operation of the conveyor belt 31, and transporting dust and dirt to the dust collecting chamber 34.

[0045] As a preferred technical solution of the present invention, the sealing component includes a sealing plate 36, a push wheel 37, an insertion rod 38 and a spring 40. The surface of the end of the dust box 29 away from the winding shaft 22 is slidably connected with the sealing plate 36, and the bottom end of the sealing plate 36 is in contact with the surface of the conveyor belt 31. The end of the rotating shaft 30 away from the winding shaft 22 is fixedly connected with a push wheel 37, and the outer wall of the push wheel 37 is in contact with the bottom surface of the sealing plate 36. Two insertion rods 38 are fixedly connected to the surface of the dust box 29. A slot 39 corresponding to the position of the insertion rod 38 is provided on the surface of the sealing plate 36. A spring 40 is fixedly connected between the top surface of the sealing plate 36 and the dust box 29.

[0046] Specifically, during the rotation of the conveyor belt 31, the two rotating shafts 30 will rotate synchronously, and the push wheel 37 will rotate accordingly. Under the action of friction, the sealing plate 36 will be driven to slide upward, thereby separating from the surface of the conveyor belt 31, so that the dust and dirt on the conveyor belt 31 can smoothly enter the dust collecting chamber 34; after dust collection is completed, under the action of the spring 40 and gravity, the sealing plate 36 slides down to fit with the conveyor belt 31, and the sealing plate 36 will seal the dust collecting chamber 34 to prevent dust and dirt from leaking out of the dust collecting chamber 34.

[0047] As a preferred technical solution of the present invention, two clamping blocks 25 are fixedly connected to one side of the power supply box 1, a strong magnetic plate 26 is fixedly connected between the two clamping blocks 25, and a soft magnetic strip 27 is fixedly connected to the tube wall of the liquid guide tube 16 on one side close to the strong magnetic plate 26.

[0048] Specifically, as the liquid guide tube 16 is pulled upward, the soft magnetic strip 27 will be adsorbed onto the strong magnetic plate 26, so that the liquid guide tube 16 is adsorbed onto the inner wall of the power supply box 1, thereby further improving the stability of the liquid guide tube 16, preventing the liquid guide tube 16 from affecting the normal operation of the power supply box 1, and avoiding safety hazards caused by the shaking of the liquid guide tube 16 during the cleaning process.

[0049] As a preferred technical solution of the present invention, a resistance sleeve 41 is fixedly connected to the outer wall of the push wheel 37 , and the resistance sleeve 41 is in contact with the bottom surface of the sealing plate 36 .

[0050] Specifically, the resistance sleeve 41 can increase the friction between the push wheel 37 and the bottom surface of the sealing plate 36, so that the sliding process of the sealing plate 36 is smoother, and the jamming or shaking caused by insufficient friction is reduced.

[0051] As a preferred technical solution of the present invention, a plurality of heat dissipation holes 28 communicating with the power chamber 7 are provided on the outer wall of the fixing block 6, and the heat dissipation holes 28 are opened obliquely downward.

[0052] Specifically, the heat dissipation holes 28 that open obliquely downward can more effectively utilize the effect of gravity to guide the hot air in the power chamber 7 to flow out and promote the inflow of external cold air. This convection effect helps to improve the heat dissipation efficiency and reduce the temperature of the power chamber 7. At the same time, it can also prevent liquid from flowing into the power chamber 7 along the heat dissipation holes 28.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
