Description

Technical Field

[0001] This utility model relates to the field of transformer cabinet technology, and in particular to a dustproof structure for transformer cabinets. Background Technology

[0002] With the development of society, the use of high and low voltage substations is becoming more and more widespread. High and low voltage substations are mainly used in power supply systems to distribute and control electrical energy in an appropriate manner. Existing high and low voltage substations are integrated devices that combine protective devices such as wires into one unit. Therefore, it can be seen that existing high and low voltage substations basically meet people's needs.

[0003] For example, Chinese utility model patent application number 202221289084.1 discloses a dustproof structure for an intelligent substation cabinet, including a substation cabinet body. A threaded groove is formed on the inner side of the substation cabinet body. A motor is fixedly connected inside the threaded groove. The output end of the motor is fixedly connected to a threaded rod via a coupling. The end of the threaded rod away from the motor is fixedly connected to the threaded groove via a bearing. A threaded block is threadedly connected to the surface of the threaded rod. A connecting block is fixedly connected to the side of the threaded block. A connecting rod is fixedly connected to the side of the connecting block. An electric push rod is fixedly connected to the surface of the connecting rod. A rectangular plate is fixedly connected to the end of the electric push rod away from the connecting rod. This utility model, through the cooperation of the threaded rod, threaded block, connecting block, connecting rod, and brush, can conveniently and automatically clean dust from the internal components of the substation cabinet, preventing dust from mixing with moisture in the air and corroding the components, thereby effectively preventing leakage.

[0004] Although the device in the aforementioned patent can clean dust from the internal components of the substation cabinet by moving the brush, in actual use, the brush in the device can only move in a single up and down direction under the drive of the drive structure, resulting in poor cleaning effect. At the same time, the lack of a collection mechanism means that the dust cleaned by the brush still floats inside the substation cabinet and easily re-adheres to the internal components, further reducing the cleaning effect.

[0033] Reference Figure 1-5This utility model provides a dustproof structure for a transformer cabinet: It includes a transformer cabinet body 1. Guide grooves 2 are provided on both sides of the inner wall of the transformer cabinet body 1. Device blocks 3 are slidably connected inside each of the two guide grooves 2. Sliding grooves 4 are provided on opposite sides of each of the two device blocks 3. Two springs 21 are fixedly connected inside the sliding grooves 4.

A filter plate 16 is provided inside the collection box 7. An exhaust port 8 is provided on the bellows 6. A drive shaft 9 is rotatably connected inside the bellows 6. One end of the drive shaft 9 rotatably passes through the bellows 6 and the support plate 5 and extends to the outside. A driven shaft 11 is rotatably connected to the back of the support plate 5. Pulleys 17 are fixedly fitted on the outer surfaces of both the drive shaft 9 and the driven shaft 11. A belt 1 is provided between the outer surfaces of the drive shaft 9 and the driven shaft 11. 2. A belt 12 is fitted onto the outer surface of two pulleys 17. A ring of brushes 13 is provided on the outer surface of the belt 12. A dust collection box 14 is fixedly connected to the back of the support plate 5. Several dust collection nozzles 15 are provided on the dust collection box 14. The collection box 7 is connected to the dust collection box 14. The main body of the substation cabinet 1 is provided with a drive assembly, a lifting assembly, and a pressing assembly. After the start motor 18 drives the drive shaft 9 and the fan plate 10 to rotate, the brushes 13 can be rotated under the combined action of the driven shaft 11, pulleys 17, belt 12, fan box 6, and dust collection box 14, which causes the dust collection nozzles 15 to generate suction. After the brushes 13 rotate, they can perform horizontal cleaning work at the same time during the up-and-down cleaning process, which improves the cleaning effect of the brushes 13. After the dust collection nozzles 15 generate suction, they can suck up and collect the dust cleaned by the brushes 13, preventing the dust from floating inside the main body of the substation cabinet 1 and adhering to the internal components of the cabinet again, which further improves the cleaning effect.

[0034] The drive assembly includes a motor 18 and several air vanes 10. The motor 18 is fixedly installed on the front of the air box 6. The output end of the motor 18 is fixedly connected to one end of the drive shaft 9. The several air vanes 10 are all fixedly connected to the outer surface of the drive shaft 9. The several air vanes 10 are arranged in a rectangular array and are all located inside the air box 6. Through the arrangement of the drive assembly, the air vanes 10 can be driven to rotate, the belt 12 can be driven to rotate, and the brush 13 can be driven to rotate to perform left and right cleaning of the components.

[0035] The lifting assembly includes a second motor 19 and a threaded rod 20. The second motor 19 is fixedly installed on the top of the main body 1 of the transformer cabinet, and the threaded rod 20 is rotatably connected between the top and bottom of the inner wall of the main body 1 of the transformer cabinet. The output end of the second motor 19 is fixedly connected to the top end of the threaded rod 20. Through the setting of the lifting assembly, the device block 3, the support plate 5 and the brush 13 can be driven to move up and down, and then the brush 13 can perform the up and down cleaning work of the components.

[0036] The extrusion assembly includes two fixed plates 22 and two extrusion rods 23. The two fixed plates 22 are fixedly connected to the inside of the main body 1 of the transformer cabinet. Several annular grooves 24 are opened on the fixed plates 22. Metal rings 25 are fixedly embedded in the annular grooves 24. Permanent magnets 26 are magnetically connected to the inside of two metal rings 25. Extrusion blocks 27 are fixedly connected to the front of the two permanent magnets 26. The two extrusion rods 23 are fixedly connected to the back of the support plate 5. Through the cooperation of the extrusion assembly and other structures, the extrusion blocks 27 can be easily installed on the fixed plates 22 and placed at the same level as some protruding components. This makes it easy for the support plate 5 and the brush 13 to push the extrusion blocks 27 away from the fixed plates 22 when they are used, preventing them from colliding with the protruding components and causing damage to the device or components, thereby improving the safety of the device during use.

[0037] Working principle: When the device is needed to remove dust from the components inside the main body 1 of the transformer cabinet, firstly, according to the size of the components, take out multiple extrusion blocks 27 and install them on two fixed plates 22 respectively, and make them at the same level as some of the more protruding components. That is, the permanent magnet 26 on the extrusion block 27 is inserted into the metal ring 25 at the appropriate position. After the permanent magnet 26 and the metal ring 25 are magnetically connected, the installation of the extrusion block 27 is completed. Then, start the motor 19 to drive the threaded rod 20 to rotate. Under the cooperation of the guide groove 2 and the support plate 5, the two device blocks 3 drive the support plate 5, the air box 6, the motor 18, the dust collection box 14 and the brush 13 to move up and down synchronously.

[0038] Then, the motor 18 is started, which drives the drive shaft 9, several fan blades 10 and one of the pulleys 17 to rotate synchronously. With the cooperation of the driven shaft 11 and the other pulley 17, the belt 12 drives the brush 13 to rotate, so that the brush 13 moves horizontally in sync with the up and down movement, which can clean the components horizontally and left and right, improving the cleaning effect of the components. When the several fan blades 10 rotate, with the cooperation of the air box 6, the gas inside the collection box 7 is drawn out to create a negative pressure, which draws in the gas inside the dust collection box 14, thereby causing the several dust nozzles 15 to generate suction, which can draw in the dust cleaned by the rotating brush 13 and transport it into the collection box 7. After being intercepted by the filter plate 16, it is collected in the collection box 7 to prevent it from spreading randomly and re-adhering to the outer surface of the components.

[0039] When the support plate 5 moves up and down and the rotating brush 13 performs cleaning work, when it encounters some protruding components, the pressing blocks 27 installed on both sides of the component cooperate to guide and press the pressing rod 23, which can compress the spring 21 and push the support plate 5 to drive the bellows 6, brush 13 and other structures to move away from the fixed plate 22, so as to prevent the drive shaft 9, driven shaft 11 and belt 12 and other structures from colliding with the protruding components.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
