Description

Technical Field

[0001] This utility model relates to the technical field of DC power supply devices, and in particular to a distributed DC power supply device. Background Technology

[0002] Distributed DC power systems are small, modular, environmentally compatible, independent power sources, typically ranging in power from several kilowatts to 50 MW. These systems are owned by power companies, electricity users, or third parties and are designed to meet specific requirements of the power system and users, such as peak shaving, supplying power to remote users or commercial and residential areas, saving on transmission and transformation investment, and improving power supply reliability.

[0003] Existing DC power supply devices, such as the prior art with application number CN202121234901.9, include a fixed mounting box, a connecting seat, a power interface, an adjustment component, a movable block, a fixed mounting limit rod, a movable plate, a limit circular rod, an adjustment disc, a connecting rod, and a dustproof plate. The limit circular rod and the adjustment disc are connected by an engagement mechanism, which allows the movable block to move back and forth when the motor is turned on and the adjustment disc is rotated. This moves the connecting seat, which is slidably connected to the fixed mounting box, and together with the dustproof plate, forms a rotating structure on the fixed mounting box. This allows the connecting seat to move forward and push open the dustproof plate, and then the power interface is used to connect to the socket.

[0004] However, existing technologies are cumbersome in terms of dust prevention at the interface and usage, which reduces convenience, and the cooling efficiency of existing technologies is also low. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a distributed DC power supply device that facilitates dustproof treatment of the connectors, improves convenience, and enhances the efficiency and quality of heat dissipation.

[0006] This utility model discloses a distributed DC power supply device, comprising a main body structure; it also includes a dustproof mechanism, a cooling mechanism, an air-cooling mechanism, a filtration mechanism, and an installation mechanism. The dustproof mechanism, cooling mechanism, air-cooling mechanism, and filtration mechanism are all mounted on the main body structure. The installation mechanism is mounted on the filtration mechanism. The dustproof mechanism protects the main body structure from dust, the air-cooling mechanism provides air cooling for the main body structure, the cooling mechanism facilitates cooling the air used for air cooling, the filtration mechanism filters the air used for air cooling, and the installation mechanism facilitates the installation and replacement of the filtration mechanism. The dustproof mechanism prevents dust from affecting the use and operation of the main body structure, the air-cooling mechanism provides air cooling for the main body structure, the cooling mechanism facilitates cooling the air used for air cooling, improving the efficiency and quality of heat dissipation, the filtration mechanism filters the air used for air cooling, and the installation mechanism facilitates the installation and replacement of the filtration mechanism, improving convenience.

[0007] Preferably, the main structure includes a DC power supply body and a connector, with the connector mounted on the DC power supply body; the connector facilitates connection to the outside world.

[0008] Preferably, the dustproof mechanism includes a dustproof plate, a sliding plate, a guide rod, a sliding block, two springs, a fixing hook, and a locking rod. A dustproof groove is provided at the connector on the DC power supply body. The dustproof plate is rotatably mounted in the dustproof groove of the connector via a rotating shaft. A sliding groove is provided on the dustproof plate, and the sliding plate is slidably mounted on the dustproof plate. The guide rod is installed in the sliding groove of the dustproof plate, and the sliding block is slidably mounted on the guide rod. The sliding block is also slidably mounted in the sliding groove of the dustproof plate and is connected to the sliding plate. One end of each of the two springs is installed at both ends of the inner wall of the sliding groove of the dustproof plate, and the other ends of the two springs are installed at both ends of the sliding block. The fixing hook is installed... On the sliding block, the side of the fixed hook that is close to the DC power supply body is inclined, and the locking rod is installed on the DC power supply body. When dust prevention of the connector is required, by rotating the dustproof plate, the inclined surface of the fixed hook contacts and presses against the locking rod, which then causes the sliding block to slide on the guide rod. When the locking rod slides to the hook of the fixed hook, the elasticity of the spring pulls the sliding block to slide back to its original position on the guide rod, thereby locking the locking rod into the fixed hook, thus completing the dust prevention treatment of the connector. When the connector is to be used, by sliding the sliding plate, the sliding block slides on the guide rod, and the locking rod contacts and fixes itself on the fixed hook, thus opening the dustproof plate.

[0009] Preferably, the cooling mechanism includes a heat exchange box, heat exchange tubes, a cooling box, a semiconductor heat sink, and a water pump. The heat exchange box is mounted on the DC power supply body, the heat exchange tubes are coiled inside the heat exchange box, the cooling box is mounted on the outer wall of the DC power supply body, the semiconductor heat sink is mounted on the cooling box, and the water pump is mounted on the outer wall of the cooling box. The water pump is equipped with a first connecting pipe that connects to one end of the heat exchange tube, and the other end of the heat exchange tube is connected to the cooling box through a second connecting pipe. First, water is added to the cooling box, and then the water in the cooling box is cooled by the semiconductor heat sink. The water pump is turned on to add water to the heat exchange tube through the first connecting pipe, and then the water is cooled by the air cooled by the air-cooling mechanism through the heat exchange tube, thereby improving the efficiency and quality of heat dissipation. After heat exchange, the water flows back to the cooling box through the second connecting pipe for further cooling.

[0010] Preferably, the air-cooling mechanism includes a fan duct, a bracket, fan blades, and a cooling motor.

The output end of the cooling motor is connected to the rotating shaft of the fan blades. By turning on the cooling motor, the fan blades are driven to rotate, thereby performing air cooling on the DC power supply body through the rotation of the fan blades.

[0011] Preferably, the filtration mechanism includes a filter mounting bracket and a filter plate. The filter mounting bracket is installed on the inner wall of the air duct, and the filter plate is installed on the filter mounting bracket through the mounting mechanism.

[0012] Preferably, the installation mechanism includes a through slot and a locking plate. The filter plate is provided with a through slot, and the locking plate is rotatably mounted on the filter mounting frame.

The dustproof mechanism 02 is installed on the main body 01, the cooling mechanism 03 is installed on the main body 01, the air-cooling mechanism 04 is installed on the cooling mechanism 03, the filtering mechanism 05 is installed on the air-cooling mechanism 04, and the installation mechanism 06 is installed on the filtering mechanism 05.

[0025] The dustproof mechanism 02 protects the main body 01 from dust, the air-cooling mechanism 04 provides air cooling for the main body 01, the cooling mechanism 03 facilitates cooling the air cooled by the air-cooling mechanism 04, the filtration mechanism 05 filters the air cooled by the air-cooling mechanism 04, and the installation mechanism 06 facilitates the installation and replacement of the filtration mechanism 05.

[0026] The main body 01 includes a DC power supply body 11 and a connector 12, with the connector 12 mounted on the DC power supply body 11;

[0027] The dustproof mechanism 02 includes a dustproof plate 21, a sliding plate 22, a guide rod 23, a sliding block 24, two springs 25, a fixing hook 26, and a locking rod 27.

[0028] When dust protection is required for connector 12, the inclined surface of the fixed hook 26 contacts and presses against the locking rod 27 by rotating the dustproof plate 21. Then, the sliding block 24 slides on the guide rod 23. When the locking rod 27 slides to the hook of the fixed hook 26, the elasticity of the spring 25 pulls the sliding block 24 to slide back to its original position on the guide rod 23, thereby locking the locking rod 27 into the fixed hook 26, thus completing the dust protection treatment of connector 12. When connector 12 is to be used, the sliding plate 22 is slid to make the sliding block 24 slide on the guide rod 23, locking the locking rod 27 from the fixed hook 26 and then opening the dustproof plate 21.

[0033] The cooling mechanism 03 includes a heat exchange box 31, a heat exchange tube 32, a cooling box 33, a semiconductor heat sink 34, and a water pump 35. The heat exchange box 31 is mounted on the DC power supply body 11. The heat exchange tube 32 is coiled inside the heat exchange box 31. The cooling box 33 is mounted on the outer wall of the DC power supply body 11. The semiconductor heat sink 34 is mounted on the cooling box 33. The water pump 35 is mounted on the outer wall of the cooling box 33. The water pump 35 is provided with a first connecting pipe that is connected to one end of the heat exchange tube 32. The other end of the heat exchange tube 32 is connected to the cooling box 33 through a second connecting pipe.

The fan duct 41 is mounted on the heat exchange box 31, the bracket 42 is mounted inside the fan duct 41, the fan blade 43 is rotatably mounted on the bracket 42 via a rotating shaft, and the cooling motor 44 is mounted on the bracket 42. The output end of the cooling motor 44 is connected to the rotating shaft of the fan blade 43.

[0035] The filtration mechanism 05 includes a filter mounting bracket 51 and a filter plate 52. The filter mounting bracket 51 is installed on the inner wall of the air duct 41, and the filter plate 52 is installed on the filter mounting bracket 51 through the mounting mechanism 06.

[0036] The mounting mechanism 06 includes a through groove 61 and a locking plate 62. The filter plate 52 is provided with a through groove 61, and the locking plate 62 is rotatably mounted on the filter mounting bracket 51.

[0037] First, water is added to the cooling box 33. Then, the water in the cooling box 33 is cooled by the semiconductor heat sink 34. The water pump 35 is turned on and the water is added to the heat exchange tube 32 through the first connecting pipe. The water is cooled by the air cooled by the air cooling mechanism 04 through the heat exchange tube 32, which improves the efficiency and quality of heat dissipation. The water after heat exchange flows back to the cooling box 33 through the second connecting pipe for further cooling. The cooling motor 44 is turned on to drive the fan blade 43 to rotate, and the fan blade 43 rotates to cool the DC power supply body 11.

[0038] like Figures 1 to 7As shown, this utility model discloses a distributed DC power supply device. During operation, when dust protection is required for connector 12, rotating the dustproof plate 21 causes the inclined surface of the fixing hook 26 to contact and press against the locking rod 27. This causes the sliding block 24 to slide on the guide rod 23. When the locking rod 27 slides to the hook of the fixing hook 26, the elastic spring 25 pulls the sliding block 24 back to its original position on the guide rod 23, thus locking the locking rod 27 onto the fixing hook 26, completing the dust protection process for connector 12. When connector 12 is to be used, sliding the sliding plate 22 causes the sliding block 24 to slide on the guide rod 23, locking the locking rod 27 from the fixing hook 26. The dustproof plate 21 can then be opened. Water is first added to the cooling box 33, and then the cooling box 33 is cooled by the semiconductor heat sink 34. The water inside is cooled by turning on the water pump 35 to add water into the heat exchange tube 32 through the first connecting pipe. The water is cooled by the air cooled by the air cooling mechanism 04 through the heat exchange tube 32, which improves the efficiency and quality of heat dissipation. The water after heat exchange flows back to the cooling box 33 through the second connecting pipe for further cooling. The cooling motor 44 is turned on to drive the fan blade 43 to rotate, and the fan blade 43 rotates to cool the DC power supply body 11. The air cooled by the air cooling mechanism 04 is filtered by the filter plate 52 to prevent dust from entering and affecting the practicality and heat dissipation of the DC power supply body 11. When the filter plate 52 needs to be replaced and reinstalled, the locking plate 62 is aligned with the through groove 61 of the filter plate 52, and then the filter plate 52 is placed on the filter mounting bracket 51. The locking plate 62 is rotated to fix the locking plate 62 to the through groove 61, which improves convenience.
