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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A shielded DC power supply panel, such as Figure 1 As shown, the DC power supply panel includes a base 2, on which a housing 1 is mounted. A door 11 is fixedly mounted on one side of the housing 1. One door 11 has an operating area, and the other door 11 has a through window 12. Shielding glass is installed inside the through window 12. The shielding glass, in addition to the electromagnetic wave reflection performance of the conductive film, also has the interference effect of the electrolyte film. Under the condition that the visible light transmittance is 50% and the frequency is 1GHz, its shielding performance is 35-60dB. The housing 1 has multiple storage compartments 13 for storing electronic components.

[0027] like Figures 2-5 As shown, the bottom of the box 1 is fixedly installed on the base 2. The base 2 has an air groove 21 that communicates with the inside of the box 1. The base 2 has symmetrically distributed slots, in which filter screens 4 are inserted. The base 2 has a pressure plate 20 fixedly installed on it, which presses the two installed filter screens 4 to prevent them from coming loose.

[0028] The base 2 has a hollow structure. An air outlet is provided on the back side of the base 2. A fan 6 is fixedly installed on the outside of the air outlet. The fan 6 has a V-shaped structure on both sides. The V-shaped structure includes two symmetrically arranged guide plates 3. The guide plates 3 are horizontally inserted into the base 2. Bolts 5 are provided on the back side of the base 2. Mounting plates 24 are fixedly installed on both sides of the fan 6. The bolts 5 pass through the ends of the two guide plates 3 on the V-shaped structure and are fixedly connected to the mounting plates 24.

[0029] A support frame 23 is fixedly installed inside the base 2 and on one side of the V-shaped structure. The support frame 23 provides auxiliary support for the inner sides of the two guide plates 3 of the V-shaped structure. One end of one guide plate 3 inside the V-shaped structure is attached to the top of the base 2, and the other end of the guide plate 3 is attached to the bottom of the base 2, forming a guide groove between the V-shaped structures. The guide plate 3 is attached to a filter screen 4, and the gas that is guided out flows through the filter screen 4. The gas with heat is located between the two filter screens 4. The fan 6 is located between the two filter screens 4. When the fan 6 is turned on, the gas between the two filter screens 4 is discharged to achieve cooling and heat dissipation.

[0030] A symmetrically distributed cover 22 is fixedly installed inside the base 2. A through groove 25 is provided inside the cover 22. A vertically arranged foot 26 is slidably installed inside the through groove 25. A horizontal groove 27 is fixedly installed at the upper end of the foot 26. A spring 29 is fitted on the foot 26. One end of the spring 29 is fixedly installed inside the through groove 25, and the other end is fixedly connected to the foot 26 to support the foot 26. A limiting rod 28 is horizontally installed inside the horizontal groove 27. The limiting rod 28 is horizontally installed inside the through groove 25.

[0031] One end of the through groove 25 is provided with an array of limiting grooves 7. The limiting grooves 7 are connected to one end of the limiting rod 28. When the limiting rod 28 slides horizontally into the limiting groove 7, it can support and limit the two feet 26. Then, the limiting rod 28 is fixed by using bolts to pass through the end of the limiting rod 28 and connect it to the outer wall of the base 2.

[0032] The components installed inside the DC power supply panel form a sealed space, and a shielding glass is installed to form a shielded DC power supply panel. This will cause the internal components to heat up when they are working, thus requiring heat dissipation.

[0033] When the fan 6 is started, it drives the airflow inside the base 2. The gas flows downward from inside the housing 1 through the air groove 21 into the base 2, and then flows through the V-shaped structure, that is, between the two guide plates 3. After passing through the filter screen 4, it is discharged from the fan 6. During this process, the gas flows from top to bottom, which can improve the heat dissipation of the gas inside the entire housing 1. Moreover, the filter screen 4 can filter the gas and prevent dusty gas below the base 2 from entering the housing 1. At the same time, the height of the base 2 can be changed by changing the engagement of the limit rod 28 with the limit groove 7 of different heights, thereby controlling the height of the DC power supply screen above the ground after installation.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
