Description

Technical Field

[0001] This invention relates to the field of transformer switchgear technology, specifically a transformer switchgear. Background Technology

[0002] Switchgear is responsible for controlling and protecting the opening and closing of circuits, similar to a "gatekeeper" in a power system. Its main task is to ensure the safe operation of the circuit. It is commonly used for the control and management of power systems, ensuring the safe operation of circuits, and is suitable for locations requiring frequent switching operations.

[0003] During use, a large amount of dust often accumulates in the ventilation mesh. This dust affects the heat dissipation efficiency of the switchgear, causing the temperature inside the switchgear to become too high and increasing the probability of safety accidents. Nowadays, when cleaning dust in the ventilation mesh, brushes are usually used. During cleaning, the dust will float in the air and does not settle easily. Furthermore, the dust can easily enter the electrical equipment inside the switchgear, causing the electrical equipment to malfunction or even short-circuit, resulting in a fire and affecting the life, health and property safety of the staff.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1. This invention cleans dust from the ventilation screen by not contacting it during the upward movement of the brush cylinder and not performing any cleaning operation on the ventilation screen, but by contacting the ventilation screen and performing a cleaning operation on the ventilation screen when the brush cylinder moves downward. Compared with the traditional up-and-down cleaning method, this cleaning method can better reduce the amount of dust that is dispersed into the air during the cleaning process, thereby reducing the possibility of it entering electrical equipment.

[0037] 2. This invention, by simultaneously stretching the elastic cloth upwards during the upward movement of the fixed rod, isolates the ventilation mesh from the inside of the frame box, thereby reducing the possibility of dust spreading inside the frame box. Furthermore, the unidirectional cleaning effect of the elastic cloth and the cleaning component ensures that dust remains between the ventilation mesh and the elastic cloth during cleaning, further enhancing the blocking effect of the elastic cloth. Additionally, by pulling the elastic cloth as the fixed rod moves upwards, it unfolds, shaking off the dust, thus automatically cleaning the surface of the elastic cloth. The cleaned dust slides through the inclined plate to the drain channel and then out of the frame box, allowing for automatic discharge of dust. This further facilitates the handling and collection of dust cleaned from the ventilation mesh by staff.

[0038] 3. This invention, through the swing of the crank rod three, in conjunction with the up-and-down movement of the brush cylinder, further achieves the effect of not spraying water when the brush cylinder moves upward, and spraying water when the brush cylinder moves to the top and then downward. At this time, combined with the blocking effect of the elastic cloth, it further achieves the effect of using liquid to wet the brush cylinder, improving the cleaning effect of the ventilation net, while also reducing the dispersion of atomized liquid in the air.

[0039] 4. This invention improves the cleaning effect of the ventilation mesh by tapping its surface during the cleaning process, causing vibration. Combined with the atomizing water spray component, the blocking component, and the cleaning component working together, it achieves the following additional effects: First, the vibration-releasing component only operates when the cleaning component is running, causing the elastic cloth in the blocking component to rise, further preventing dust from scattering in the air when tapping the ventilation mesh surface. Second, the tapping plate, together with the elastic cloth, creates an insulating effect, better isolating the atomized water between the tapping plate and the elastic cloth during the operation of the atomizing water spray component, further preventing the atomized water from scattering inside the frame box. Third, the plate-shaped tapping plate generates airflow during tapping, blowing any remaining dust out of the ventilation mesh and onto the outside of the frame box, further improving the cleaning effect of the ventilation mesh.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1, please refer to Figures 1 to 14 This embodiment provides a technical solution: a transformer switchgear, including a frame box 1, a cleaning box 5 fixedly connected to the outer surface of the frame box 1, and a ventilation assembly inside the frame box 1, the ventilation assembly including:

[0057] The ventilation net 8 and the frame box 1 have slots on their outer surfaces that extend into the interior. The walls of the slots are connected to the sides of the ventilation net 8. The frame box 1 also has a trough 9 on its side, which is located below the ventilation net 8.

[0058] More specifically, in this embodiment: electrical equipment such as transformers are installed in the switch cabinet, and then the door 3 is closed. Next, the transformer and electrical equipment work in the frame box 1. The heat generated by the transformer and electrical equipment when they are powered on will be dissipated from the frame box 1 through the ventilation net 8, thereby achieving the purpose of heat dissipation.

[0059] The ventilation assembly utilizes the ventilation net 8 to dissipate the heat generated by the transformer and electrical equipment inside the frame box 1, thereby reducing the probability of damage to the transformer and electrical equipment inside the frame box 1 due to high temperature.

[0060] It is worth noting that this embodiment also includes: an external component disposed inside the frame box 1, the external component including:

[0061] The raised block 2, door 3 and handle 4, the surface of the frame box 1 has a through groove, the groove wall is hinged to the surface of door 3, the surface of door 3 is connected to the surface of handle 4, the upper surface of raised block 2 is connected to the lower surface of frame box 1, and the surface of door 3 is also fixedly connected to display screen 7.

[0062] More specifically, in this embodiment: the setting of the shim block 2 allows space to be created between the bottom of the switch cabinet and the ground when using the switch cabinet, further preventing the possibility of short circuits in the transformer and electrical equipment inside the switch cabinet on a damp ground. Furthermore, the setting of the door 3, handle 4, and display screen 7 further facilitates the use of the electrical equipment, thereby improving the practicality of the switch cabinet.

[0063] Example 2, based on the above examples:

[0064] Please see Figures 1 to 14 In this embodiment, the cleaning box 5 is equipped with a cleaning component, which includes:

[0065] The system consists of a fixed plate 24, a handle 6, and a rotating shaft 14. The end face of the handle 6 is connected to the surface of the rotating shaft 14, which rotates through the surface of the cleaning box 5. A fixed block 22 is connected to the end face of the fixed plate 24, and the end face of the fixed block 22 is connected to the inner wall of the cleaning box 5. One end of the fixed plate 24 has a through hole, and the groove wall of the through hole is rotatably connected to the surface of the rotating shaft 14. A crank rod 23 is fixedly connected to the end surface of the rotating shaft 14 away from the handle 6. A crank rod 20 is hinged to the end face of the crank rod 23 away from the rotating shaft 14. A crank rod 37 is hinged to the center end face of the crank rod 20. The end of the crank rod 37 away from the crank rod 20 is rotatably connected to the surface of the fixed plate 24. A through slot is opened at the end of the crank rod 20 away from the crank rod 37. A fixed rod 42 is fixedly connected to the surface of the through slot, and a brush cylinder 31 is rotatably connected to the surface of the fixed rod 42.

[0066] More specifically, in this embodiment: when the frame box 1 is cooled by the ventilation net 8 for a long time, a large amount of dust will accumulate on the surface of the ventilation net 8. This dust will affect the heat dissipation effect of the ventilation net 8, so it is necessary to clean the ventilation net 8. During cleaning, the transformer and electrical equipment inside the frame box 1 are de-energized. Then, the handle 26 is turned to drive the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 will further drive the crank rod 23 to rotate. The rotation of the crank rod 23 will drive the crank rod 20 to move. And through the restriction of the crank rod 3 17, the crank rod 3 17 is further driven to swing, while the crank rod 20 also swings, thereby causing the fixed rod 42 to have the following two motion states:

[0067] Firstly, when the fixed rod 42 moves the brush cylinder 31 upward, the curved rod 20 will move the fixed rod 42 in a semi-circular curve, so that the brush cylinder 31 does not contact the ventilation screen 8 during the upward movement.

[0068] Secondly, when the fixed rod 42 moves the brush cylinder 31 downward, the curved rod 20 will move the fixed rod 42 downward in a straight line, which will further cause the brush cylinder 31 to roll on the surface of the ventilation mesh 8, thereby brushing off the dust on the ventilation mesh 8.

[0069] The brush cylinder 31 does not contact the ventilation screen 8 during its upward movement and does not perform a cleaning operation on the ventilation screen 8. When the brush cylinder 31 moves downward, it contacts the ventilation screen 8 and performs a cleaning operation on the ventilation screen 8, thus achieving a one-way cleaning effect.

[0070] This cleaning assembly is designed to clean dust from the ventilation screen 8 by not contacting it during the upward movement of the brush cylinder 31, and only contacting it during the downward movement of the brush cylinder 31. Compared to traditional up-and-down cleaning methods, this cleaning method can better reduce the amount of dust dispersed into the air during the cleaning process, thereby reducing the possibility of it entering electrical equipment.

[0071] Example 3, based on the above examples:

[0072] Please see Figures 1 to 14 In this embodiment, a blocking component is provided inside the frame box 1, and the blocking component includes:

[0073] The system includes a fixed plate 40, an elastic cloth 32, and an inclined plate 33. The lower end face of the elastic cloth 32 is connected to the upper end face of the inclined plate 33. The lower end face of the inclined plate 33 is connected to the inner wall of the frame box 1, and the side of the elastic cloth 32 is slidably connected to the inner wall of the frame box 1. The surface of the inclined plate 33 corresponds to the groove 9. The end face of the fixed plate 40 has a through groove. The groove wall is rotatably connected to the surface of the fixed rod 42. The fixed plate 40 is connected to the upper end face of the elastic cloth 32. The surface of the fixed plate 40 is also fixedly connected to a connecting block 48. The surface of the connecting block 48 abuts against the surface of the ventilation net 8.

[0074] More specifically, in this embodiment: during the upward movement of the first fixed rod 42, the second fixed plate 40 pulls the elastic cloth 32 upward. Since the path of the first fixed rod 42 is arc-shaped during the upward movement, it can further pull the elastic cloth 32, so that the elastic cloth 32 can be better unfolded, thereby better shaking off the dust on the elastic cloth 32.

[0075] This blocking component is designed to separate the ventilation mesh 8 from the inside of the frame box 1 by simultaneously stretching the elastic cloth 32 as the fixed rod 42 moves upward, thereby reducing the possibility of dust spreading inside the frame box 1. Furthermore, the elastic cloth 32, in conjunction with the unidirectional cleaning effect of the cleaning component, ensures that dust remains between the ventilation mesh 8 and the elastic cloth 32 during cleaning, further enhancing the blocking effect of the elastic cloth 32. Additionally, as the fixed rod 42 moves upward, it pulls the elastic cloth 32, causing it to unfold and shaking off the dust, thus automatically cleaning the surface of the elastic cloth 32. The cleaned dust then slides through the inclined plate 33 to the drain 9 and out of the frame box 1, allowing for automatic discharge of dust from the frame box 1. This further facilitates the handling and collection of dust cleaned from the ventilation mesh 8 by staff.

[0076] Example 4, based on the above examples:

[0077] Please see Figures 1 to 14 In this embodiment, the cleaning box 5 is further provided with an atomizing water spraying assembly, which includes:

[0078] One-way valve 27, one-way valve 26, fixed column 21, water tank 12, water inlet pipe 13, and fixed bracket 11 are provided. The outer surface of water tank 12 is connected to the inner wall of cleaning box 5. The upper surface of water tank 12 is fixedly connected to one end of water inlet pipe 13. A through-hole is provided on the upper surface of cleaning box 5, and the surface of the through-hole is connected to the surface of water inlet pipe 13. The surface of fixed bracket 11 is connected to the inner wall of cleaning box 5. An arc-shaped piston cylinder 10 is fixedly connected to the inner wall of fixed bracket 11. The surface of fixed column 21 is connected to the end face of fixed plate 24. An arc-shaped sliding bracket 15 is also fixedly connected to the end face of fixed column 21. A sliding column 16 is slidably connected to the inner wall of arc-shaped sliding bracket 15. A through mounting groove is provided on the end face of crank rod 3 17. The groove wall is connected to the end surface of sliding column 16. A sleeve 28 is fixedly connected to the surface of sliding column 16. An arc-shaped piston cylinder 10 is fixedly connected to the surface of sleeve 28. Piston 18, the rod end surface of the arc-shaped piston 18 slides through the inner wall of the arc-shaped sliding frame 15, and the plate end surface of the arc-shaped piston 18 is slidably connected to the inner wall of the arc-shaped piston cylinder 10. The inlet end of the one-way valve 26 is fixedly connected to the end surface of the arc-shaped piston cylinder 10. The outlet end of the one-way valve 26 is fixedly connected to the hose 19. The end of the hose 19 away from the one-way valve 26 is connected to the surface of the connecting block 48. The connecting block 48 has a cavity inside. The end surface of the hose 19 is fixedly connected to the cavity. The surface of the cavity inside the connecting block 48 is also fixedly connected to the atomizing nozzle rod 47. The atomizing nozzle rod 47 is located below the brush cylinder 31. The outlet end of the one-way valve 27 is fixedly connected to the end surface of the arc-shaped piston cylinder 10. The inlet end of the one-way valve 27 is fixedly connected to the fixed pipe 25. The end of the fixed pipe 25 away from the one-way valve 27 is fixedly connected to the interior of the water tank 12.

[0079] More specifically, in this embodiment: rotating the handle 26 drives the rotating shaft 14 to rotate, and further, the crank rod 13 and the crank rod 20 drive the crank rod 317 to swing around the connection between the fixed plate 14 and the crank rod 317, thereby causing the sliding column 16 on the crank rod 317 to slide within the arc-shaped sliding frame 15, and then the arc-shaped piston 18 to slide within the arc-shaped piston cylinder 10 through the sleeve 28. This further enables the cleaning assembly to achieve the following two motion states:

[0080] Firstly, when the brush cylinder 31 moves upward, the sliding column 16 slides to the left inside the arc-shaped sliding frame 15, which further drives the arc-shaped piston 18 to move away from the bottom of the arc-shaped piston cylinder 10 inside the arc-shaped piston cylinder 10, thereby cooperating with the one-way valve 26 and the one-way valve 27 to inject water into the arc-shaped piston cylinder 10.

[0081] Secondly, when the brush cylinder 31 moves to the top, it contacts the surface of the ventilation mesh 8. At this time, the sliding column 16 slides to the right in the arc-shaped sliding frame 15, further driving the arc-shaped piston 18 to move towards the bottom of the arc-shaped piston cylinder 10. With the unidirectional flow of the one-way valve 26 and the one-way valve 27, the liquid in the arc-shaped piston cylinder 10 is sprayed out from the atomizing nozzle rod 47 through the hose 19.

[0082] The atomizing water spray assembly is designed so that the swing of the crank rod 317, in conjunction with the up-and-down movement of the brush cylinder 31, further achieves the effect of not spraying water when the brush cylinder 31 moves upward, and spraying water when the brush cylinder 31 moves to the top and then moves downward. At this time, the elastic cloth 32 acts as a barrier, which further achieves the effect of using liquid to wet the brush cylinder 31, improving the cleaning effect on the ventilation net 8, while also reducing the dispersion of the atomized liquid in the air.

The back tooth surface of straight tooth row 29 is fixedly connected to the inner wall of frame box 1. The tooth surface of straight tooth row 29 meshes with the tooth surface of toothed ring 41. The inner wall of toothed ring 41 is rotatably connected to the surface of fixed rod 42. A through rotating groove is opened on the end face of triangular piece 43. The groove wall is rotatably connected to the surface of fixed rod 42. The end face of triangular piece 43 is connected to the end face of toothed ring 41.

The surface of block 51 abuts against the end surface of sliding post 36. A spring 50 is fixedly connected to the surface of block 51 away from sliding post 36. The end of spring 50 away from block 51 is connected to the wall of sliding groove 49. The wall of sliding frame 37 is slidably connected to the surface of sliding post 36. The outer surface of sliding frame 37 is connected to the surface of fixed plate 45. A connecting plate 34 is connected to the end face of sliding post 36 away from actuation frame 35. A straight tooth row 38 is fixedly connected to the surface of connecting plate 34. The tooth surface of straight tooth row 38... A toothed ring 39 is engaged with the inner wall of the toothed ring 39, which is rotatably connected to the surface of the fixed rod 44. A striking plate 30 is connected to the end face of the toothed ring 39, and a through rotating opening is provided on the end face of the striking plate 30. The groove wall of the rotating opening is rotatably connected to the surface of the fixed rod 44. A limiting groove is provided in the groove wall of the sliding frame 37. A square block is fixedly connected to the surface of the sliding column 36 that is slidably connected to the sliding frame 37. The surface of the square block is slidably connected to the groove wall of the limiting groove, so that the sliding column 36 can only slide on the groove wall of the sliding frame 37 and cannot rotate.

[0086] More specifically, in this embodiment: when the crank rod 20 drives the fixed rod 42 to perform an arc-shaped motion when rising and a linear motion when falling, the following two motion states are achieved:

[0087] Firstly, when the fixed rod 42 moves upward, due to the curved motion, the toothed ring 41 and the straight tooth row 29 do not mesh, and the striking plate 30 does not strike the ventilation screen 8.

[0088] Secondly, when the fixed rod 42 moves upward to the top and then downward, the toothed ring 41 meshes with the tooth surface of the straight tooth row 29. The downward movement of the fixed rod 42 further drives the toothed ring 41 to roll on the surface of the straight tooth row 29, thus causing the toothed ring 41 to rotate. This further drives the triangular piece 43 to rotate clockwise, thereby continuously pushing the actuating frame 35 to swing around the fixed rod 44. This achieves the following: when the end of the actuating frame 35 near the triangular piece 43 moves upward, under the restriction of the sliding frame 37, the sliding column 36 in the sliding groove 49 will move towards the fixed rod 44, further squeezing the sliding block 51 and thus squeezing it. Spring 50 simultaneously drives sliding column 36 to slide within sliding frame 37, further driving straight tooth row 38 to move, thereby causing toothed ring 39 to rotate, driving the tapping plate 30 to rotate around fixed rod 44. When triangular piece 43 disengages from one end of toggle frame 35, spring 50 releases pressure, further driving sliding column 36 and toggle frame 35 to return to their original positions, and further driving sliding column 36 to return to its original position within sliding frame 37. Then, through the movement of straight tooth row 38, toothed ring 39 rotates in the opposite direction, thereby causing tapping plate 30 to tap the surface of ventilation mesh 8, causing the surface of ventilation mesh 8 to vibrate and loosen the dust on the surface of ventilation mesh 8.

[0089] The vibration loosening component is designed to improve the cleaning effect by tapping the surface of the ventilation mesh 8 during the cleaning process. This vibration further enhances the cleaning efficiency of the ventilation mesh 8. Combined with the atomizing water spray component, the blocking component, and the cleaning component working together, it provides the following additional effects: First, the vibration loosening component only operates when the cleaning component is in use. At this time, the elastic cloth 32 in the blocking component also rises, further preventing dust from scattering into the air when tapping the surface of the ventilation mesh 8. Second, the tapping... The plate 30, together with the elastic cloth 32, can form an isolation effect, better isolating the atomized water between the plate 30 and the elastic cloth 32 during the operation of the atomizing water spray component, thereby further preventing the atomized water from drifting in the frame box 1. Thirdly, because the plate 30 is plate-shaped, by fanning the plate 30, airflow is generated during the beating process, blowing the dust that has not been cleaned out of the ventilation net 8 and falling outside the frame box 1, further improving the cleaning effect of the ventilation net 8.

[0090] Working principle: When using this type of transformer switchgear, the following steps are performed:

[0091] During cleaning, the transformer and electrical equipment inside frame box 1 are de-energized. Then, handle 26 is turned to drive rotating shaft 14 to rotate. The rotation of rotating shaft 14 will further drive crank rod 23 to rotate. The rotation of crank rod 23 will drive crank rod 20 to move. And through the restriction of crank rod 317, crank rod 317 will be further driven to swing. At the same time, crank rod 20 will also swing, thereby causing fixed rod 42 to have the following two motion states:

[0092] Firstly, when the fixed rod 42 moves the brush cylinder 31 upward, the curved rod 20 will move the fixed rod 42 in a semi-circular curve, so that the brush cylinder 31 does not contact the ventilation screen 8 during the upward movement. During the upward movement of the fixed rod 42, the elastic cloth 32 will be pulled upward by the fixed plate 2 40, and the elastic cloth 32 will be unfolded. At the same time, the sliding column 16 slides to the left in the arc-shaped sliding frame 15, which further drives the arc-shaped piston 18 to move away from the bottom of the arc-shaped piston cylinder 10 in the arc-shaped piston cylinder 10. This, in turn, cooperates with the one-way valve 26 and the one-way valve 27 to inject water into the arc-shaped piston cylinder 10, and makes the toothed ring 41 and the straight tooth row 29 not mesh, further preventing the beater plate 30 from beating the ventilation screen 8.

[0093] Secondly, when the fixed rod 42 moves the brush cylinder 31 downwards, the curved rod 20 will cause the fixed rod 42 to move downwards in a straight line, further causing the brush cylinder 31 to roll on the surface of the ventilation mesh 8, thereby brushing off the dust on the ventilation mesh 8. At this time, the descent of the fixed rod 42 causes the elastic cloth 32 to gradually contract, and when the brush cylinder 31 moves to the top, it contacts the surface of the ventilation mesh 8. At this time, the sliding column 16 slides to the right in the arc-shaped sliding frame 15, further driving the arc-shaped piston 18 to move in the arc-shaped piston cylinder 10. The bottom movement, combined with the one-way flow of one-way valve 26 and one-way valve 27, allows the liquid in the arc-shaped piston cylinder 10 to be sprayed out from the atomizing nozzle rod 47 through the hose 19. Simultaneously, the toothed ring 41 meshes with the toothed surface of the straight toothed row 29. The downward movement of the fixed rod 42 further drives the toothed ring 41 to roll on the surface of the straight toothed row 29, causing the toothed ring 41 to rotate. This further drives the triangular piece 43 to rotate clockwise, continuously pushing the actuating frame 35 to swing around the fixed rod 24. This achieves the effect that when the end of the actuating frame 35 near the triangular piece 43 moves upward, under the constraint of the sliding frame 37, the sliding column 36 in the sliding groove 49 will move towards the fixed rod 24. The movement further compresses the sliding block 51, thereby compressing the spring 50. Simultaneously, it drives the sliding column 36 to slide within the sliding frame 37, further driving the straight tooth row 38 to move, thus causing the toothed ring 39 to rotate. This causes the striking plate 30 to rotate around the fixed rod 44. When the triangular piece 43 disengages from one end of the toggle frame 35, the spring 50 releases pressure, further driving the sliding column 36 and the toggle frame 35 to return to their original positions. It also further drives the sliding column 36 to return to its original position within the sliding frame 37. Then, the movement of the straight tooth row 38 causes the toothed ring 39 to rotate in the opposite direction, thereby causing the striking plate 30 to strike the surface of the ventilation mesh 8, causing the surface of the ventilation mesh 8 to vibrate and loosen the dust on the surface of the ventilation mesh 8.
