Technical Field
[0001] This utility model belongs to the field of DC power supply technology, specifically a distributed DC power supply device. Background Technology
[0002] A DC power supply is a device that maintains a constant voltage and current in a circuit. It has two electrodes, positive and negative. When the two electrodes are connected to the circuit, they can maintain a constant potential difference between the two ends of the circuit, thereby forming a current from the positive to the negative electrode in the external circuit. There are many ways to assemble it, among which distributed DC power supply devices are particularly important.
[0003] A search revealed that patent CN221597084U discloses a distributed DC power supply device, comprising a main body, a fan on top of a motor, nozzles on the side of an air duct, a vacuum cleaner on the side of the main body, a suction pipe on the side of a dust collection box, and a suction port on top of the suction pipe. When the distributed DC power supply device is operating, the main body generates significant heat, leading to high internal heat. When this heat is generated, the motor drives the fan, which delivers airflow into the air duct, which is then blown out by the nozzles. This combined action of the fan, air duct, and nozzles effectively cools the main body of the power supply. Furthermore, the multiple nozzles ensure comprehensive heat dissipation for the entire main body.
[0004] Analysis of the above technical solutions reveals that, because the suction port is located at the bottom of the dust filter, the upper part of the filter is difficult to clean. Furthermore, lint and other impurities easily float in the outside air and adhere to the surface of the dust filter, making it difficult to clean using only the suction component, thus reducing the cleaning effect. Therefore, we provide a distributed DC power supply device to solve these problems. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides a distributed DC power supply device.

[0025] 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.
[0026] like Figure 1-9As shown, this embodiment proposes a distributed DC power supply device, including a cabinet 1. Dustproof nets 7 and positioning slots 12 are provided on both sides of the cabinet 1. The positioning slots 12 are located below the dustproof nets 7, and the length of the positioning slots 12 is greater than the width of the dustproof nets 7. Two U-shaped frames 6 are fitted onto the surface of the cabinet 1, and the U-shaped frames 6 are slidably disposed on both sides of the cabinet 1. Two fixing frames 10 are provided outside each positioning slot 12, and the fixing frames 10 are slidably disposed on the side of the cabinet 1. The two fixing frames 10 are respectively located on both sides of the positioning slot 12. The bottom ends of the two U-shaped frames 6 are respectively fixed to the corresponding fixing frames. On frame 10, when the two U-shaped frames 6 are pulled upwards, they can pull each fixed frame 10 upwards together. Side plates 13 are movably connected to both fixed frames 10, allowing the side plates 13 to move on the fixed frames 10. A lint roller 15 and a dust cover 9 are detachably connected between the two side plates 13. The dust cover 9 is fitted over the surface of the lint roller 15 and contacts the surface of the cabinet 1. The dust cover 9 provides dust protection for the lint roller 15, ensuring normal subsequent use. Furthermore, both the lint roller 15 and the dust cover 9 are easily detachable between the two side plates 13, which is beneficial for future use. Continue replacing or removing used adhesive paper from the lint roller 15. Insert the lint roller 15 into the corresponding positioning slot 12. When the lint roller 15 is not in use, ensure it is inserted into the positioning slot 12 to prevent dust and lint from adhering to its surface. A dust extraction mechanism is installed at the top of the cabinet 1. With the above structure, personnel can perform regular cleaning using the dustproof net 7 without the need for additional electrical equipment. In operation, simply pull the two U-shaped frames 6 upwards to simultaneously raise the two lint rollers 15, causing them to separate from the positioning slots 12. The lint roller 15 can respectively adhere to the dust and lint on the surfaces of the two dustproof nets 7. After the lint roller 15 has finished cleaning the dustproof nets 7, the personnel remove the dust cover 9 from between the two side plates 13, then peel off the adhesive paper used on the lint roller 15, and then fix the dust cover 9 back between the two side plates 13. Finally, push down the two U-shaped frames 6 to move the lint roller 15 into the corresponding positioning groove 12 for subsequent use. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0027] like Figure 3 , Figure 4 , Figures 6 to 9As shown, a movable block 20 is slidably disposed on the inner wall of the fixed frame 10. A second guide rod 22 is fixedly connected to the surface of the movable block 20. One end of the second guide rod 22 extends through to one side of the fixed frame 10. A second spring 19 is sleeved on the surface of the second guide rod 22, and both ends of the second spring 19 are fixedly connected to the surface of the movable block 20 and the inner wall of the fixed frame 10, respectively. An mounting sleeve 17 is fixedly connected to the middle of the side plate 13, and both ends of the lint roller 15 are respectively inserted into the corresponding mounting sleeve 17. A first guide rod 16 is fixedly connected to the middle of the mounting sleeve 17, and one end of the first guide rod 16 extends through the middle of the movable block 20. A first spring 18 is sleeved on the surface of the first guide rod 16, and both ends of the first spring 18 are fixedly connected to the side plate 10 and the inner wall of the fixed frame 10, respectively. The lint roller 15 is fixed to the surface of the movable block 20 and the surface of the mounting sleeve 17, respectively. With the above structure, when the lint roller 15 is used up and is in the positioning groove 12, the second spring 19 will push the movable block 20 and move the side plate 13 together, so that the protruding side of the lint roller 15 can be inserted into the positioning groove 12, thus ensuring the cleaning effect of the lint roller 15. When the lint roller 15 moves upward, the two side plates 13 will drive the two first guide rods 16 to move outward, thereby pushing the two movable blocks 20 to move, so that the lint roller 15 can squeeze and adhere lint and dust on the surface of the dustproof net 7, improving the cleaning effect of the dustproof net 7.
[0028] like Figures 4 to 6 , Figure 8 and Figure 9 As shown, each side plate 13 has two opposing blocks 21 fixedly connected to its surface, and each dust cover 9 has two opposing elastic clamping plates 14 fixedly connected to both ends. The dust cover 9 is snapped onto the corresponding two side plates 13 by the elastic clamping plates 14, and the elastic clamping plates 14 are in contact with the blocks 21. With the above structure, the dust cover 9 can be easily snapped between the two side plates 13, thereby achieving a dustproof effect on the lint roller 15 and preventing external dust and lint from adhering to the surface of the lint roller 15 and affecting subsequent use. When it is necessary to remove the dust cover 9, simply pull the dust cover 9 outward. It can be removed from between the two side plates 13 so that personnel can remove the lint roller 15 from its surface. When it is necessary to fix the dust cover 9, simply put the dust cover 9 on the surface of the corresponding side plate 13 through the elastic clamp 14. Since the elastic clamp 14 is elastic, it prevents the dust cover 9 from easily falling between the two side plates 13. When the subsequent fixing frame 10 rises, the lint roller 15 will press against the surface of the dust net 7, so the dust cover 9 and the side plate 13 will move outward. During this process, the dust cover 9 can be firmly fixed between the two side plates 13 without falling off.
[0029] like Figure 1 and Figure 3As shown, the vacuuming mechanism includes a dust collection box 2 and a vacuum cleaner 3. Both the dust collection box 2 and the vacuum cleaner 3 are installed on the upper surface of the cabinet 1, and the dust discharge end of the vacuum cleaner 3 is connected to the dust collection box 2. The dust suction end of the vacuum cleaner 3 is connected to two opposing vacuum suction hoses 4. Two vacuum suction frames 8 are fixed between two U-shaped frames 6, and the two vacuum suction frames 8 are respectively located above two dust covers 9. The bottom ends of the two vacuum suction hoses 4 are respectively connected to the two vacuum suction frames 8. With the above structure, when cleaning the dust cover 7 begins, the vacuuming is activated. The operation of device 3 causes the suction hose 4 and suction frame 8 to start suctioning. When the person pulls the U-shaped frame 6 upward, the suction frame 8 will rise together and extract the lint and dust deep inside the dustproof net 7, and transport it to the dust collection box 2 for unified collection and processing. In conjunction with the lint roller 15, it can stick the lint and dust on the surface of the dustproof net 7, making the dustproof net 7 more thoroughly cleaned. In addition, when the suction frame 8 rises, the suction hose 4 will also swing upward, which will not affect the suction of the dustproof net 7 by the suction frame 8.
[0030] like Figure 1 As shown, a handle 5 is provided at the top of the cabinet 1. The two ends of the handle 5 are fixed to the top of the two U-shaped frames 6 respectively, and the handle 5 is located above the dust collection box 2. With the handle 5, it is easy for personnel to control the synchronous lifting and lowering of the two lint rollers 15. When the handle 5 is pulled upward, it will pull the two U-shaped frames 6 to rise together, which can simultaneously drive each fixed frame 10 to rise. Finally, it can drive the two lint rollers 15 to rise synchronously, and achieve the effect of cleaning the two dust screens 7 at the same time, which improves the cleaning efficiency of the dust screens 7. Moreover, no additional drive equipment is required to drive them, thus saving costs.
[0031] like Figure 2 As shown, two guide grooves 11 are provided on both sides of the cabinet 1. One end of each fixed frame 10 is slidably set in the corresponding guide groove 11 by a slider. The setting of the guide groove 11 can ensure the stability of the fixed frame 10 when sliding on the side of the cabinet 1, and prevent the fixed frame 10 from tilting at will. This ensures the stability of the lint roller 15 during use and prevents the lint roller 15 from tilting at will. In addition, since the U-shaped frame 6 is U-shaped, the U-shaped frame 6 will not move left or right or back and forth, but can only move up and down.
[0032] The working principle and usage process of this utility model: When personnel perform positioning maintenance and inspection on cabinet 1, they can clean the dustproof nets 7 according to their usage. When it is necessary to clean the two dustproof nets 7, first pull the handle 5 upward to move the two U-shaped frames 6 upward, which will cause the two lint rollers 15 to separate from the two positioning grooves 12 and rise synchronously, so that the two lint rollers 15 can respectively adhere to the dust and lint on the surface of the two dustproof nets 7. At the same time, the vacuum cleaner 3 is used to start the vacuum hose 4 and the vacuum frame 8 to start the suction. The vacuum frame 8 The system extracts lint and dust deep inside the dustproof net 7 and transports them to the dust collection box 2 for unified collection and treatment, thereby improving the cleaning effect of the dustproof net 7 and making the cleaning method more comprehensive. After the lint roller 15 finishes cleaning the dustproof net 7, the personnel remove the dust cover 9 from between the two side plates 13, then remove the adhesive paper used on the lint roller 15, and then fix the dust cover 9 back between the two side plates 13. Finally, push the handle 5 down to move the lint roller 15 into the corresponding positioning groove 12 for subsequent use.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
