Technical Field
[0001] This utility model relates to the field of power supply equipment technology, specifically a dual-circuit high-voltage power supply switching device for mines. Background Technology
[0002] The core production equipment in a mine, such as the main ventilation fan, hoist, underground water pump, and crushing station, all rely on high-voltage power to drive. Once such equipment loses power, it will cause serious consequences. The dual-circuit high-voltage power switching equipment for mines is an important electrical device used in the mine power supply system to ensure that the main power supply can be quickly switched to the backup power supply when the main power supply fails, so as to ensure the continuous operation of the mine equipment.
[0003] However, the environment in mines is harsh, and the dual-circuit high-voltage power switching equipment in mines generates a lot of heat during operation. The heat dissipation efficiency of existing dual-circuit high-voltage power switching equipment in mines is relatively low, and high temperatures can easily damage the components of the dual-circuit high-voltage power switching equipment in mines, posing certain safety hazards.
[0004] In view of this, we propose a dual-circuit high-voltage power supply switching device for mines. Utility Model Content
[0005] The purpose of this utility model is to provide a dual-circuit high-voltage power supply switching device for mines to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A dual-circuit high-voltage power switching equipment for mining includes a box, an internal parts compartment, an exhaust pipe on the side wall of the box, a cooling fan fixedly installed inside the exhaust pipe, a baffle fixedly connected to the inner wall of the parts compartment, multiple exhaust holes on the inner wall of the baffle, an air inlet on the side wall of the parts compartment, a filter device on one side of the air inlet, and a support base fixedly connected to the bottom of the box.
[0008] When the equipment inside the parts compartment is running, the cooling fan can be activated to extract the heat generated by the equipment. The combination of the baffle and the exhaust vent prevents the generation of localized strong airflow when the cooling fan extracts heat from the parts compartment, thus avoiding heat accumulation. The exhaust vent on the baffle can evenly distribute the airflow path, guiding hot air from different areas of the parts compartment to the cooling fan more evenly, reducing the generation of localized high-temperature dead zones. Meanwhile, cool air from outside will enter the interior of the parts compartment through the air inlet, forming an airflow circulation and improving heat dissipation efficiency.
[0009] Preferably, the filtration device includes a filter chamber on the side wall of the parts compartment, and the filter chamber is located on one side of the air inlet. A support frame is slidably connected to the inner wall of the filter chamber, and a filter screen is fixedly connected to the inner wall of the support frame.
[0010] When cold air from the outside enters the parts compartment through the air inlet, it is filtered by the filter screen on the support frame inside the filter compartment to remove dust and impurities from the cold air. This prevents the dust and impurities from entering the parts compartment, covering the equipment components, affecting their heat dissipation, and improving safety during use.
[0011] Preferably, a fixed magnetic strip is fixedly connected to the inner wall of the filter chamber, and the fixed magnetic strip is magnetically connected to the support frame;
[0012] When the support frame slides into the filter chamber, the fixing magnetic strip will magnetically attract the support frame, fixing it inside the filter chamber and improving safety during use.
[0013] Preferably, the side walls of the support frame are fixedly connected with absorbent sponges;
[0014] By installing a water-absorbing sponge, when cold outside air passes through the air inlet and the filter, it will pass through the water-absorbing sponge located between the filter and the air inlet. At this time, the water-absorbing sponge will absorb the moisture in the cold air, preventing moisture from entering the parts compartment and reducing safety hazards.
[0015] Preferably, the side wall of the support frame is fixedly connected to two handles;
[0016] By setting a handle, pulling the handle can help slide the support frame out of the filter chamber, making it easy to remove the support frame and clean the dust and dirt on it, thus improving the convenience of use.
[0017] Preferably, a dustproof net is fixedly connected to the side wall of the exhaust duct;
[0018] By installing a dust filter, external dust and impurities are filtered out, preventing them from entering the parts compartment through the exhaust duct and improving safety during use.
[0019] Preferably, the air inlet and exhaust vents are arranged symmetrically;
[0020] The symmetrically arranged air inlets and outlets allow airflow to pass directly through the outlets of the baffle, forming a directional airflow that prevents airflow from meandering or stagnating inside the parts compartment. This airflow then flows directly through the equipment components inside the parts compartment, absorbs heat, and is quickly drawn out by the cooling fan through the symmetrical outlets of the baffle, improving heat dissipation efficiency.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This dual-circuit high-voltage power supply switching device for mining allows for the activation of cooling fans to extract heat generated during equipment operation within the parts compartment. The combination of baffles and exhaust vents prevents localized strong airflow and heat accumulation during heat extraction. Furthermore, the exhaust vents on the baffles evenly distribute airflow, guiding hot air from different areas within the parts compartment to the cooling fans more uniformly, reducing localized high-temperature dead zones. Meanwhile, cool air from outside enters the parts compartment through the air inlets, creating airflow circulation and improving heat dissipation efficiency.
[0023] 2. This dual-circuit high-voltage power supply switching equipment for mining allows external cold air to enter the parts compartment through the air inlet. The filter screen on the support frame in the filter compartment filters out dust and impurities in the cold air, preventing these dust and impurities from entering the parts compartment and covering the equipment components, thus affecting the heat dissipation of the equipment components and improving the safety of use.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0030] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:
[0031] A dual-circuit high-voltage power switching device for mining includes a housing 1. The housing 1 has a parts compartment 2 inside, and an exhaust pipe 3 is provided on the side wall of the housing 1. A cooling fan 4 is fixedly installed inside the exhaust pipe 3. A baffle 5 is fixedly connected to the inner wall of the parts compartment 2, and multiple exhaust holes 6 are provided on the inner wall of the baffle 5. An air inlet 7 is provided on the side wall of the parts compartment 2, and a filter device is provided on one side of the air inlet 7. A support base 15 is fixedly connected to the bottom surface of the housing 1. When the equipment inside the parts compartment 2 is in operation, a cooling system can be activated. The fan 4 extracts the heat generated by the internal equipment of the parts compartment 2 during operation. The baffle 5 and the exhaust vent 6 work together to prevent the generation of local strong airflow when the cooling fan 4 extracts heat from the parts compartment 2, thus avoiding heat accumulation. The exhaust vent 6 on the baffle 5 can evenly distribute the airflow path, guiding the hot air in different areas of the parts compartment 2 to flow more evenly to the cooling fan 4 through the exhaust vent 6, reducing the generation of local high-temperature dead zones. Meanwhile, the cool air from the outside will enter the interior of the parts compartment 2 through the air inlet vent 7, forming an airflow circulation and improving heat dissipation efficiency.
[0032] In this embodiment, the filtration device includes a filter chamber 8 on the side wall of the parts compartment 2, and the filter chamber 8 is located on one side of the air inlet 7. A support frame 9 is slidably connected to the inner wall of the filter chamber 8, and a filter screen 10 is fixedly connected to the inner wall of the support frame 9. When cold air from the outside enters the interior of the parts compartment 2 through the air inlet 7, the filter screen 10 on the support frame 9 in the filter chamber 8 will filter the dust and impurities in the cold air, preventing these dust and impurities from entering the interior of the parts compartment 2 and covering the equipment components, affecting the heat dissipation of the equipment components, and improving the safety of use.
[0033] In this embodiment, a fixing magnetic strip 11 is fixedly connected to the inner wall of the filter chamber 8, and the fixing magnetic strip 11 is magnetically connected to the support frame 9. When the support frame 9 slides into the filter chamber 8, the fixing magnetic strip 11 will magnetically attract the support frame 9, fixing the support frame 9 inside the filter chamber 8, thereby improving the safety of use.
[0034] In this embodiment, a water-absorbing sponge 12 is fixedly connected to the side wall of the support frame 9. By setting the water-absorbing sponge 12, when the outside cold air passes through the air inlet 7 and the filter screen 10, it will pass through the water-absorbing sponge 12 located between the filter screen 10 and the air inlet 7. At this time, the water-absorbing sponge 12 will absorb the moisture in the cold air, preventing the moisture from entering the parts compartment 2 and reducing safety hazards.
[0035] In this embodiment, two handles 13 are fixedly connected to the side wall of the support frame 9. By setting the handles 13, pulling the handles 13 can help drive the support frame 9 to slide out of the filter chamber 8, making it convenient to take out the support frame 9 to clean the dust and dirt on it, thus improving the ease of use.
[0036] In this embodiment, a dustproof net 14 is fixedly connected to the side wall of the exhaust pipe 3; by setting the dustproof net 14, the dustproof net 14 will filter the dust and impurities from the outside, preventing these dust and impurities from entering the parts compartment 2 from the exhaust pipe 3, thereby improving the safety of use.
[0037] In this embodiment, the air inlet 7 and the exhaust vent 6 are symmetrically arranged. The airflow through the air inlet 7 will directly pass through the exhaust vent 6 of the baffle 5 to form a directional airflow, avoiding the airflow from meandering and stagnating inside the parts compartment 2. After absorbing heat, the airflow will be quickly drawn out by the cooling fan 4 through the symmetrical exhaust vent 6 of the baffle 5, thus improving the heat dissipation efficiency.
[0038] In this embodiment, a dual-circuit high-voltage power supply switching device for mining is used such that, during the operation of the equipment inside the parts compartment 2, the cooling fan 4 can be activated to extract the heat generated by the equipment during operation. Through the cooperation of the baffle 5 and the exhaust hole 6, the generation of local strong airflow when the cooling fan 4 extracts heat from the parts compartment 2 is avoided, which would lead to heat accumulation. In addition, the exhaust hole 6 on the baffle 5 can evenly distribute the airflow path, guiding the hot air in different areas of the parts compartment 2 to flow more evenly to the cooling fan 4 through the exhaust hole 6, reducing the generation of local high-temperature dead zones. Meanwhile, the cold air from the outside will enter the interior of the parts compartment 2 through the air inlet 7, forming an airflow circulation and improving the heat dissipation efficiency.
[0039] When cold air from the outside enters the interior of the parts compartment 2 through the air inlet 7, it will be filtered by the filter screen 10 on the support frame 9 in the filter compartment 8 to remove dust and impurities from the cold air. This prevents the dust and impurities from entering the interior of the parts compartment 2, covering the equipment components, affecting the heat dissipation of the equipment components, and improving the safety of use.
