Description

Technical Field

[0001] This utility model relates to the field of high and low voltage power distribution equipment technology, and in particular to a high and low voltage power distribution cabinet maintenance device. Background Technology

[0002] In modern society, electricity has become an indispensable resource for people's lives and work. High and low voltage switchgear, as a crucial component of the power system, plays a vital role in distributing, controlling, and protecting electrical energy. High and low voltage switchgear refers to equipment used in power systems for power generation, transmission, distribution, energy conversion, and consumption, performing functions such as switching, control, and protection. However, due to long-term use and environmental impacts, switchgear is prone to malfunctions, posing potential risks to power safety. Therefore, regular maintenance and upkeep are essential to ensure the normal operation of switchgear and extend its service life. While seemingly insignificant, the dust in switchgear can cause serious hazards, even threatening personal safety. Therefore, in enterprise operations, it is crucial to pay close attention to the cleanliness of the switchgear environment, strengthen maintenance management, and ensure the safe and stable operation of the equipment.

[0003] Currently, distribution cabinets require regular cleaning. Due to prolonged operation, static electricity accumulates on the electrical components inside the cabinet, attracting a large amount of dust. This dust can enter the equipment, reducing its operational stability and potentially causing tripping, burnout, and other problems, impacting production and operations. This is especially true in high-reliability environments such as hospitals and laboratories. Traditional distribution cabinets lack maintenance devices, requiring maintenance personnel to clean the entire cabinet regularly. Cleaning the cabinet necessitates disassembling the internal electrical components for cleaning and drying, or using a vacuum cleaner to remove dust from the surface. This process is inefficient, and delayed cleaning can lead to frequent electrical malfunctions. Furthermore, the internal electrical components are prone to overheating, causing excessively high overall temperatures and damaging the components. Utility Model Content

[0004] This utility model provides a high and low voltage distribution cabinet maintenance device, which solves the problems of traditional distribution cabinets that cannot be maintained in a timely manner, which easily leads to dust accumulation and failure of internal electrical components over a long period of time, and low heat dissipation efficiency of electrical components, which easily leads to high temperature failure.

[0005] This utility model provides a high and low voltage switchgear maintenance device, including a cabinet and a cabinet door installed on the cabinet. An air inlet is provided on one side wall of the cabinet, and an air outlet is provided on the other side wall. One end of the air inlet is connected to a first air duct installed on the inner side wall of the cabinet, and the other end is connected to a first air box installed on the outer side wall of the cabinet. A vertically placed first filter tube is installed inside the first air box. The upper end of the first filter tube is sealed to the top plate of the first air box, and the lower end of the first filter tube extends through the bottom plate of the first air box to the bottom of the first air box. One end of the air outlet is connected to a second air duct installed on the inner side wall of the cabinet. One end is connected to the other end, which is connected to a second air box installed on the outer side wall of the cabinet. A vertically placed second filter tube is installed inside the second air box. The upper end of the second filter tube is sealed to the top plate of the second air box, and the lower end of the second filter tube extends through the bottom plate of the second air box to the bottom of the second air box. A first sealing cover is installed at the lower end of the first filter tube, and a second sealing cover is installed at the lower end of the second filter tube. A cold air fan is installed on the rear side wall of the cabinet. The air supply port of the cold air fan is connected to the lower side wall of the second filter tube through an air supply pipe, and the air exhaust port of the cold air fan is connected to the lower side wall of the first filter tube through an exhaust pipe.

[0006] In the above technical solution, two swing plates are further provided on both sides of the cabinet body, and air holes are provided on the opposite surfaces of the two swing plates. Each swing plate has a cavity inside, and the cavity is connected to the air hole. The cavity of one swing plate is connected to the first air duct, and the cavity of the other swing plate is connected to the second air duct.

[0007] In the above technical solution, each swing plate is further provided with two rotating shafts on its upper and lower end faces, and the two rotating shafts are respectively inserted into the top side wall and bottom side wall of the cabinet for rotatable connection.

[0008] In the above technical solution, each swing plate is further provided with an electric telescopic rod at its upper end for driving it to rotate horizontally along the pivot axis.

[0011] As can be seen from the above technical solutions, this utility model provides a high and low voltage distribution cabinet maintenance device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Air from inside the distribution cabinet is drawn into the first air box through the first air duct and air inlet by a cooler. Dust in the air is filtered into the first air box by the first filter tube. The filtered clean air then enters the second filter tube and is introduced into the air supply duct. From there, it enters the second air box and is delivered into the distribution cabinet through the air outlet and the second air duct. This continuous air circulation purifies and removes dust within the distribution cabinet. The cool air generated by the cooler also cools the electrical components inside the distribution cabinet, preventing them from overheating and malfunctioning. This allows for timely maintenance, dust removal, and cooling of the distribution cabinet, increasing the lifespan of the electrical components and reducing the failure rate of the distribution cabinet.

[0014] 2. The electric telescopic rod drives two swing plates to horizontally blow and suck up dust from the surface of electrical components, preventing dust from settling downwards and facilitating the rapid cleaning and collection of the blown dust. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1:

[0032] See Figure 1-5A high and low voltage switchgear maintenance device includes a cabinet 1 with a door at the front. An air inlet 11 is located on one side wall of the cabinet 1, and an air outlet 12 is located on the other side wall. The inner end of the air inlet 11 is sealed and connected to a first air duct 13 located on the inner side wall of the cabinet 1. A first air box 2 is fixedly installed on the outer side wall of the cabinet 1. The outer end of the air inlet 11 communicates with the inner cavity of the first air box 2 through a through hole in the side wall of the first air box 2. A vertically arranged first filter pipe 3 is installed inside the first air box 2. The upper end of the first filter pipe 3 is sealed and fixedly connected to the top plate of the first air box 2, and the lower end of the first filter pipe 3 penetrates the bottom of the first air box 2. The plate extends below the first air box 2. The inner end of the air outlet 12 is connected to the second air duct 14 provided on the inner side wall of the cabinet 1. The second air box 4 is fixedly installed on the outer side wall of the cabinet 1. The outer end of the air outlet 12 is connected to the inner cavity of the second air box 4 through a through hole provided on the side wall of the second air box 4. A vertically placed second filter pipe 5 is provided inside the second air box 4. The upper end of the second filter pipe 5 is sealed to the top plate of the second air box 4. The lower end of the second filter pipe 5 extends through the bottom plate of the second air box 4 to the bottom of the second air box 4. A first sealing cover 31 is provided at the lower end of the first filter pipe 3, and a second sealing cover 51 is provided at the lower end of the second filter pipe 5. A cooler 6 is installed on the rear wall of cabinet 1. The cooler 6 is a commercially available device. The air supply port of the cooler 6 is connected to the lower side wall of the second filter pipe 5 through the air supply pipe 61, and the air exhaust port of the cooler 6 is connected to the lower side wall of the first filter pipe 3 through the exhaust pipe 62. The air circulation of the cooler 6 causes the air inside the distribution cabinet to enter the first air box 2 through the first air pipe 13 and the air inlet 11. The first filter pipe 3 filters the dust in the air into the first air box 2. The filtered clean air enters the second filter pipe 5 and is introduced into the air supply pipe 61, then enters the second air box 4 and exits through the air outlet 12. The second air duct 14 delivers air into the distribution cabinet, allowing the air inside the cabinet to circulate continuously for purification. The air cooler 6 increases the airflow to blow away dust from the electrical components inside the distribution cabinet and cools them with cold air to prevent them from overheating and malfunctioning. The cleaned dust is quickly drawn into the first air box 2 and filtered through the first filter pipe 3, trapping the dust inside the first air box 2. This allows for timely maintenance, dust removal, and cooling of the distribution cabinet, increasing the lifespan of the electrical components inside and reducing the failure rate of the distribution cabinet.

[0033] In this embodiment, see Figure 3 , 45. Two swing plates 7 are installed on both sides inside the cabinet 1. Air holes 71 are provided on the opposite surfaces of the two swing plates 7. Each swing plate 7 has a cavity inside, which is connected to the air hole 71. The cavity of one swing plate 7 is connected to the first air duct 13, and the cavity of the other swing plate 7 is connected to the second air duct 14. The air inside the cabinet 1 is exhausted from the swing plate 7 on the left side of the cabinet 1 by the action of the air cooler 6. It enters its cavity through the air hole 71 on the swing plate 7 on the left side of the cabinet 1, and then is introduced into the first air box 2 for filtration through the first air duct 13. The swing plate 7 on the right side of the cabinet 1 is used for air supply. It regularly blows away the dust on the surface of the electrical components inside the cabinet 1 as well as the dust in the air, so that the blown dust is quickly absorbed and collected, preventing dust from accumulating on the surface of the electrical components.

[0034] In this embodiment, see Figure 5 Each swing plate 7 has two rotating shafts 72 on its upper and lower end faces. The two rotating shafts 72 are respectively inserted into the pivot holes set on the top and bottom side walls of the cabinet 1 for positioning and rotational connection.

[0035] In this embodiment, see Figure 5 Each swing plate 7 is equipped with an electric telescopic rod 73 at its upper end for driving it to rotate horizontally along the pivot 72. One end of the electric telescopic rod 73 is hinged to the first hinge seat on the top plate of the cabinet 1, and the other end is hinged to the second hinge seat on the side wall of the swing plate 7. By extending and retracting the electric telescopic rod 73, the angle of the swing plate 7 can be adjusted, and the blowing direction of the power distribution components can be adjusted to achieve multi-angle dust blowing and cooling of the power components.

[0036] In this embodiment, see Figure 2 A heat dissipation vent is provided on the rear wall of the cabinet 1 and connected to a heat dissipation pipe 15. The heat generated by the electrical appliances inside the cabinet 1 is allowed to dissipate freely through the heat dissipation vent 15. An air valve is installed on the heat dissipation pipe 15 to control the airflow between the heat dissipation pipe 15 and the inside of the cabinet 1, so that dust can be effectively collected during the dust removal process of electrical components.

[0037] In this embodiment, see Figure 4 The first filter pipe 3 is located on the side wall inside the first air box 2 and the second filter pipe 5 is located on the side wall inside the second air box 4, both of which are covered with through-hole ventilation holes. The outer wall of the first filter pipe 3 inside the first air box 2 and the outer wall of the second filter pipe 5 inside the second filter pipe 5 are both covered with filter cloth 8. The dust passing through the filter cloth 8 is filtered through the filter cloth 8 to prevent excessive dust from accumulating on the electrical components inside the cabinet 1 and causing damage to the electrical components.

[0038] In this embodiment, see Figure 1 , 2A first inspection door 21 is provided on the outer wall of the first air box 2, and a second inspection door 41 is provided on the outer wall of the second air box 4. The first inspection door 21 and the second inspection door 41 facilitate opening the first air box 2 and the second air box 4 to clean the dust accumulated inside the first air box 2 and the second air box 4.

[0039] In this embodiment, see Figure 5 Both the first duct 13 and the second duct 14 are retractable corrugated pipes, so that the oscillating plate 7 can extend or retract its length during rotation, thus preventing interference between the oscillating plate 7 and the first duct 13 and the second duct 14 during rotation.

[0040] In this embodiment, the air cooler 6 and the electric telescopic rod 73 are electrically connected and controlled by the controller. The air cooler 6 is a commercially available device, including a compressor, evaporator, condenser expansion valve and fan. A temperature sensor is installed in the distribution cabinet. When the temperature sensor detects that the temperature inside the distribution cabinet is too high, it transmits the temperature information to the controller. The controller then controls the air cooler 6 to cool the electrical components inside the distribution cabinet. This not only cools the electrical components but also removes dust and purifies the air inside the distribution cabinet.

[0041] As can be seen from the above technical solution, when dust removal is required inside the distribution cabinet, the controller controls the air cooler 6 to circulate air, causing the air inside the distribution cabinet to enter the first air box 2 through the first air duct 13 and air inlet 11. The filter cloth 8 on the first filter tube 3 filters the dust from the air into the first air box 2. The filtered clean air enters the second filter tube 5 and is then introduced into the air supply duct 61, and then into the second air box 4. It is then sent into the distribution cabinet through the air outlet 12 and the second air duct 14, allowing the air inside the distribution cabinet to circulate continuously for purification. The cleaned dust is then... Dust is quickly drawn into the first air box 2 and filtered through the first filter pipe 3, trapping it inside. The air cooler 6 increases airflow to clean the electrical components inside the distribution cabinet. Additionally, when the temperature of the components inside the cabinet is too high, the air cooler 6 switches to cooling mode, circulating cold air to lower the temperature of the components, preventing them from overheating and malfunctioning. This allows for timely maintenance, dust removal, and cooling of the distribution cabinet, increasing the lifespan of the components and reducing the failure rate.
