Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a mining-grade encapsulated and intrinsically safe DC regulated power supply. Background Technology

[0002] The intrinsically safe and encapsulated DC regulated power supply for mining is a power supply device specifically designed for special environments such as mines. It features encapsulation and intrinsic safety, ensuring safe and reliable operation in flammable and explosive environments. However, DC regulated power supplies used inside mines are typically designed to be relatively enclosed to prevent coal dust, particulate matter, and methane from entering the power supply and causing an explosion. However, existing mining DC regulated power supplies often lack external heat dissipation components, leading to insufficient heat dissipation during operation. This can cause overload and short circuits, and the power supply is susceptible to vibration from explosions, affecting its stable operation. Therefore, we propose the intrinsically safe and encapsulated DC regulated power supply for mining to address these issues. Utility Model Content

[0003] (a) Technical problems to be solved

The input port and two output ports of the power supply body slide through the housing and extend to its exterior. Two sets of protective components for protecting the output ports of the power supply body are provided on one side wall of the housing. Two connecting plates are fixed to the bottom of the heat sink, and two buffer rods are rotatably connected to the bottom of each connecting plate via pins. Two damping buffers are fixed to the inner walls of both sides of the housing. The other ends of the buffer rods are respectively connected to pins...

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of this utility model discloses a mine-use encapsulation and intrinsically safe DC regulated power supply, including a housing 1. A heat sink 2 slides inside the housing 1. Guide rails 17 are fixed to both inner walls of the housing 1. Guide plates 18, adapted to the guide rails 17, are fixed to both inner walls of the heat sink 2, providing guidance and support for the heat sink 2 to ensure stability during buffered movement. A power supply body 3 is fixed inside the heat sink 2. The input port and two output ports of the power supply body 3 slide through the housing 1 and extend to its exterior. Two sets of power supply input ports are provided on one side wall of the housing 1 for the power supply body 3. The protective component 4 protects the outlet port. Two connecting plates 5 are fixed to the bottom of the heat sink 2. Each connecting plate 5 has two buffer rods 6 rotatably connected to its bottom via pins. Two damping buffers 7 are fixed to the inner walls of both sides of the housing 1. The other ends of the buffer rods 6 are rotatably connected to the corresponding damping buffers 7 via pins. A water tank 8 is fixed to the bottom of the housing 1. A water inlet pipe 20 is fixed to one side wall of the water tank 8. A pipe cap is threaded to the top of the water inlet pipe 20, making it easier to add cooling water to the water tank 8 later. Heat dissipation blocks 9 are fixed inside the openings on both sides of the water tank 8. Semiconductor cooling chips 10 are fixed to one side wall of the heat sink 9. A pump body 11 is fixed to the top of the housing 1. A water supply pipe 12 is fixed to the water inlet end of the pump body 11. Both ends of the water supply pipe 12 are fixed to the water tank 8. A U-shaped pipe 13 is fixed to the water outlet end of the pump body 11. Both ends of the U-shaped pipe 13 extend through the housing 1 and into its interior, and are fixed to the two water inlet hoses of the heat sink 2. The two water outlet hoses of the heat sink 2 are fixed to the top of the water tank 8. When using this mining-grade encapsulation and intrinsically safe DC regulated power supply, the semiconductor cooling chips 10 can be used to cool the water inside the water tank 8. Continuous cooling is achieved by starting pump 11, which delivers cooling water from inside water tank 8 to heat sink 2 via water pipe 12. As the cooling water flows within heat sink 2, it carries away the heat generated by the power supply unit 3 during operation. The used cooling water then flows back to water tank 8 for reuse. If the housing 1 is subjected to the impact of a mine blast after being fixed, the connecting plate 5, buffer rod 6, and damping buffer 7 will provide cushioning protection for the power supply unit 3. Three through holes are provided on the housing 1 to allow space for the input and output ports of the power supply unit 3. Figure 1It can be seen that an elastic protective mesh is installed inside the through hole, which can prevent external dust from entering the interior of the housing 1 through the through hole, and at the same time, it can avoid interference to the power supply body 3 when it moves due to buffering.

[0026] like Figure 2 and Figure 6 As shown, in some embodiments, the protective component 4 includes an annular seat 401 fixed to one side wall of the housing 1. One end of the annular seat 401 is inserted into a protective cover 402. A cathode magnetic ring 403 is fixed on the annular seat 401, and an anode magnetic ring 404 is fixed on the protective cover 402. The anode magnetic ring 404 and the cathode magnetic ring 403 are attracted to each other. A connecting strap 405 is fixed to the surface of the annular seat 401. The other end of the connecting strap 405 is fixedly connected to one side wall of the protective cover 402. In use, the cooperation between the annular seat 401 and the protective cover 402 can seal and protect the output port of the power supply body 3 when not in use. The two are connected and fixed by magnetic attraction, which makes it easier to install and disassemble them. Furthermore, the connecting strap 405 allows the two to be connected, so that the protective cover 402 will not separate from the annular seat 401 after disassembly, thus preventing the protective cover 402 from being lost.

[0027] like Figure 3 As shown, in some embodiments, two agitator paddles 14 are rotatably connected inside the water tank 8 via bearings. Each agitator paddle 14 has a synchronous wheel 15 fixed on its surface. The two synchronous wheels 15 are connected by a synchronous belt 16. In use, with the cooperation of the synchronous wheels 15 and the synchronous belt 16, the two agitator paddles 14 can be driven to rotate after a dustproof motor is started. After the agitator paddles 14 rotate, they can stir the cooling water inside the water tank 8 so as to mix the cooling water inside it evenly.

[0028] like Figure 4 As shown, in some embodiments, two sets of inclined plates 19 are fixed inside the heat sink 2 to extend the flow time of cooling water. The inclined plates 19 can extend the flow time of cooling water inside the heat sink 2, thereby more comprehensively removing the heat generated by the power supply body 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
