Description

Technical Field

[0001] This utility model belongs to the field of substation technology, and in particular relates to a ventilation and dust prevention device for use in substations. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electrical energy generated by generators before feeding it into the high-voltage power grid. During the operation of a substation, dust prevention is crucial. If dust directly enters the substation, it will cover the surfaces of the electrical equipment, affecting heat dissipation efficiency, causing overheating, and consequently reducing equipment performance and lifespan. Simultaneously, dust may degrade the insulation performance of electrical equipment, increasing the risk of short circuits and electric shocks, thus potentially leading to safety accidents.

[0003] Existing dust control devices generally use dust screens to block outside air from directly entering the substation. This traditional method has low dust control efficiency, and the fixed structure of the dust screen makes it impossible to clean it in time when the mesh is blocked, resulting in reduced heat dissipation efficiency of the substation. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation and dust prevention device for substations. Through the action of a filter tube, this device can filter the air entering the substation, preventing dust from entering the transformer cabinets and avoiding dust accumulation that could lead to decreased insulation performance, increased equipment failure rate, or even short circuits or fires. The filter tube effectively reduces dust damage to electrical equipment, improving operational reliability. Furthermore, the filter tube is designed to be easily disassembled and cleaned by staff, solving the problems of low dust prevention efficiency in existing methods and the inability to clean clogged dust screens in a timely manner, which reduces the substation's heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0023] The present invention is further configured such that: a support plate is fixed at the bottom of the ventilation duct body, and one end of the support plate is in contact with the bottom of the filter tube.

[0041] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7 This utility model is a ventilation and dust prevention device applied to a substation, including a ventilation duct body 1, with a filter device 2 fixed to one end of the ventilation duct body 1; the filter device 2 includes a filter shell 3, with a ventilation opening 4 on the surface of the filter shell 3, a connecting frame 5 fixed to the outside of the ventilation opening 4, and a positioning rod 6 fixed to one side of the connecting frame 5; a connecting rod 7 fixed to one end of the positioning rod 6, and an adjusting block 8 fixed to one end of the connecting rod 7; a movable block 9 movably connected to the outer ring of the connecting rod 7; a positioning strip 10 fixed to the outside of the filter shell 3; an installation frame 11 sleeved on the outside of the positioning strip 10, with a filter tube 12 fixed to one side of the installation frame 11; an adjusting tube 13 fixed to one side of the installation frame 11, with an installation plate 14 fixed to one end of the adjusting tube 13; an adjusting groove 15 opened on the inner wall of the installation plate 14, with a first spring 16 fixed inside the adjusting groove 15; a locking block 17 fixed to one end of the first spring 16, and an adjusting rod 18 fixed to one end of the locking block 17.

[0042] Specifically, one end of the locking block 17 has a triangular structure; the movable block 9 has a disc-shaped structure; and one end of the adjusting block 8 has a hemispherical structure fixed.

[0043] Furthermore, a second spring 19 is fixed to the outer ring of the connecting frame 5, and a fastening plate 20 is fixed to one end of the second spring 19; a sealing strip 21 is fixed to one side of the fastening plate 20, and the sealing strip 21 contacts one end of the mounting frame 11.

[0044] The operation process of this embodiment is as follows: During use, the end of the filter tube 12 away from the ventilation duct body 1 is connected to the substation. After connection, the motor 23 can be turned on. The output shaft of the motor 23 drives the fan blade 24 at one end to rotate, which blows air into the filter tube 12. After the filter tube 12 filters the air, it blows it into the substation. When the filter tube 12 needs to be cleaned after a period of use, the filter plate 26 can be pulled out from the filter tube 12, and then the filter tube 12 is pushed to move towards the ventilation duct body 1. When the filter tube 12 moves towards the ventilation duct body 1, the locking block 17 moves towards the ventilation duct body 1, that is, it slides from between the adjusting block 8 and the movable block 9 to the side of the movable block 9 away from the movable block 9. At this time, the filter tube is pulled. 12. Slide the locking block 17 away from the ventilation duct body 1. At this time, the locking block 17 drives the movable block 9 to move towards the adjusting block 8, and the movable block 9 touches the adjusting block 8. Due to the disc-shaped arc surface of the movable block 9, the locking block 17 slides across the surfaces of the movable block 9 and the adjusting block 8, and the adjusting tube 13 can be removed from the outer ring of the positioning rod 6. This device can filter the air entering the substation to prevent dust from entering the transformer cabinet, avoid dust accumulation leading to decreased insulation performance, increased equipment failure rate, or even short circuit or fire. Through the filter tube 12, the damage of dust to electrical equipment can be effectively reduced, and the operational reliability of the equipment can be improved. The filter tube 12 is designed to be flexibly disassembled, which is convenient for staff to disassemble and clean in a timely manner.

[0045] For a specific embodiment two, please refer to Figure 5-6 Based on the first specific embodiment, a bracket 22 is fixed inside the ventilation duct body 1; a motor 23 is fixed at one end of the bracket 22, and a fan blade 24 is fixed on the output shaft of the motor 23.

[0046] Specifically, the upper surface of the filter tube 12 has several placement grooves 25, and the filter plate 26 is movably connected inside the placement grooves 25; the bottom of the inner wall of the filter tube 12 is fixed with a limiting strip 27, and the bottom of the filter plate 26 is stuck between two adjacent limiting strips 27.

[0047] Furthermore, a support plate 28 is fixed at the bottom of the ventilation duct body 1, and one end of the support plate 28 is in contact with the bottom of the filter pipe 12.

[0048] The operation process of this embodiment is as follows: When in use, the filter plate 26 installed in the filter tube 12 is an activated carbon plate. When it is necessary to clean or replace the filter plate 26, the filter plate 26 can be pulled upward to remove it from the placement groove 25. When it is necessary to install the filter plate 26 back into the filter tube 12, one side of the filter plate 26 can be aligned with the placement groove 25 and the filter plate 26 can be inserted into the filter tube 12. At the same time, the bottom of the filter plate 26 is locked between the two limiting strips 27 to ensure the stability of the filter plate 26 during use and to prevent the airflow generated when the air passes through the filter tube 12 from causing the filter plate 26 to shake, and to prevent dust from passing through the gap between the inner wall of the filter tube 12 and the filter plate 26.
