Description

Technical Field

[0001] The utility model relates to the technical field of network engineering equipment, in particular to a protection device for a low-voltage power supply used in network engineering. Background Technique

[0002] There are two ways to divide high and low voltage power supplies. One is based on the safety of people, that is, voltages below 36V are low voltages, and voltages above 36V are high voltages; and a more commonly used way of dividing is that voltages below 1kV (AC) are called low voltages, and voltages above 1kV are called high voltages; low-voltage power supplies are mainly used for demonstration experiments and laboratories to obtain low-voltage AC, DC, and regulated power supplies.

[0003] In the prior art, such as a protection device for a low-voltage power supply used in network engineering in Chinese Patent CN211508332U, it includes a protector body, an installation groove, a connecting column, a connecting hole, a connecting sleeve, a movable cavity, a heat dissipation box, an inclined plate, a wing bolt, a filter screen plate, a cross plate, a water absorption pad, a side groove, a threaded hole, an ear plate, a through hole, a limiting plate, a spring, and a limiting hole. The heat dissipation box can be directly clamped inside the side groove, and the heat dissipation box can be fixed to the protector body through the wing bolt. The installation and disassembly are relatively simple. At the same time, a cross plate is provided inside the heat dissipation box, and a water absorption pad is fixedly connected to the side of the cross plate. The water absorption pad can absorb the water stains entering the heat dissipation box from the outside; the device is fixed by passing a screw through the connecting hole. When subjected to external vibration, relative sliding will occur between the connecting column and the connecting sleeve. Under the action of the limiting plate, the spring on the surface of the connecting column can be compressed to buffer the protector body and play a protective role for the installation structure of the protector body.

[0004] In the above patent, although the heat dissipation box can be fixed to the protector body through the wing bolt, and the installation and disassembly are relatively simple, however, the high temperature generated by the low-voltage power supply is naturally discharged outward through a plurality of heat dissipation holes. During long-term use, it is easy for more heat to gather inside the protective shell and cannot be quickly discharged, which is likely to affect the service life of the low-voltage power supply. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the high temperature generated by the low-voltage power supply is naturally discharged outward through a plurality of heat dissipation holes.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A protection device for a low-voltage power supply used in a network project, comprising: a protective shell, on both outer surfaces of which a plurality of heat dissipation holes are evenly formed; a heat dissipation component, which is provided in two groups, and the two groups of heat dissipation components are symmetrically arranged on the front surface of the protective shell. The heat dissipation component includes a fixed frame, a support frame is fixedly connected to the inner surface of the fixed frame, a motor is fixedly connected to the rear surface of the support frame, a rotating rod is fixedly connected to the output end of the motor, and a plurality of fan blades are equidistantly arranged on the outer surface of the rotating rod; an installation component, which is provided in two groups, and the two groups of installation components are respectively arranged on the front surfaces of the two fixed frames. The installation component includes a fixing plate.

[0007] Preferably, square grooves are symmetrically formed on the front surface of the protective shell, and the two fixed frames are respectively located inside the two square grooves.

[0008] Preferably, butterfly bolts are arranged at the positions near the four corners on the front surface of the fixing plate. The outer surfaces of the plurality of butterfly bolts sequentially pass through the outer surfaces of the fixing plate and the fixed frame and extend into the protective shell. The outer surface of the butterfly bolt is in threaded rotation connection with the inner wall of the protective shell.

[0009] Preferably, a circular groove is formed on the front surface of the fixing plate, and a filter screen is provided in a matching manner inside the circular groove.

[0010] Preferably, stoppers are symmetrically arranged on the front surface of the fixing plate, and the stoppers are provided in a matching manner with the filter screen.

[0011] Preferably, a connecting rod is fixedly connected to the rear surface of the stopper, and the outer surface of the connecting rod is rotatably connected to the inner wall of the fixing plate.

Under the action of the high-speed airflow, the high temperature gathered inside the protective shell is quickly discharged from the multiple heat dissipation holes on both sides, which effectively avoids the heat accumulation inside the protective shell, improves the heat dissipation effect inside the protective shell, and solves the problem in the background technology that a lot of heat is easily gathered inside the protective shell and cannot be quickly discharged, thereby affecting the service life of the low-voltage power supply.

[0015] 2. In the utility model, when in use, multiple blocks are moved in sequence, and the connecting rods and circular blocks fixedly connected thereto will rotate within a limited position in the inner wall of the fixed plate, so that when the blocks are rotated to the other side or are parallel to both sides of the fixed plate, the filter screen that needs to be cleaned can be conveniently taken out of the circular groove for cleaning or replacement, which is highly practical.

[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1 - 5 shown, the present utility model provides a protection device for a low-voltage power supply used in network engineering, including: a protection shell 1, and a plurality of heat dissipation holes 4 are uniformly opened on the outer surfaces of both sides of the protection shell 1; a heat dissipation component 2, and the heat dissipation component 2 is provided in two groups, and the two groups of heat dissipation components 2 are symmetrically arranged on the front surface of the protection shell 1. The heat dissipation component 2 includes a fixed frame 201, a support frame 202 is fixedly connected to the inner surface of the fixed frame 201, a motor 203 is fixedly connected to the rear surface of the support frame 202, a rotating rod 204 is fixedly connected to the output end of the motor 203, and a plurality of fan blades 205 are equidistantly arranged on the outer surface of the rotating rod 204; an installation component 3, and the installation component 3 is provided in two groups, and the two groups of installation components 3 are respectively arranged on the front surfaces of the two fixed frames 201. The installation component 3 includes a fixing plate 301, square grooves 5 are symmetrically opened on the front surface of the protection shell 1, and the two fixed frames 201 are respectively located inside the two square grooves 5. Butterfly bolts 302 are arranged at the positions near the four corners on the front surface of the fixing plate 301. The outer surfaces of the plurality of butterfly bolts 302 sequentially pass through the outer surfaces of the fixing plate 301 and the fixed frame 201 and extend into the interior of the protection shell 1. The outer surface of the butterfly bolt 302 is threadedly rotatably connected to the inner wall of the protection shell 1. A circular groove 303 is opened on the front surface of the fixing plate 301, and a filter screen 304 is provided in a matching manner inside the circular groove 303.

[0025] The effect achieved by the entire Embodiment 1 is that when the protection device for the low-voltage power supply in network engineering is in use, the low-voltage power supply is fixedly arranged at the inner bottom of the protection shell 1. Then, the two fixing frames 201 are respectively placed into the two square grooves 5 in the correct direction in sequence. Next, the two fixing plates 301 are respectively attached to the front surfaces of the two fixing frames 201. A plurality of matching wing bolts 302 are sequentially inserted through the fixing plates 301 and the fixing frames 201, and the wing bolts 302 are manually rotated, so that during the rotation, they are threadedly connected to the protection shell 1, thereby driving the fixing plates 301 to squeeze the fixing frames 201, and making them fixed to the front side of the protection shell 1. Synchronously start the two motors 203 fixed to the rear sides of the support frames 202. When the output ends of the motors 203 drive the rotating rods 204 to rotate, the plurality of fan blades 205 fixedly arranged on their surfaces rotate synchronously. Under the high-speed rotation of the two groups of a plurality of fan blades 205, external air will be pumped into the protection shell 1. When the external air penetrates the filter screen 304, the dust and impurities in the air will be filtered and then enter the protection shell 1, and blow on the surface of the low-voltage power supply. Under the action of the high-speed air flow, the high-temperature gas in the protection shell 1 will quickly discharge from the plurality of heat dissipation holes 4, effectively avoiding the accumulation of heat inside the protection shell 1, improving the heat dissipation effect inside the protection shell 1, and solving the problem in the background technology that it is easy to accumulate more heat inside the protection shell and cannot be quickly discharged, thereby affecting the service life of the low-voltage power supply.

[0026] Embodiment 2: As Figures 1 - 5 shown, stoppers 305 are symmetrically arranged on the front surface of the fixing plate 301. The stoppers 305 are arranged in a matching manner with the filter screen 304. A connecting rod 306 is fixedly connected to the rear surface of the stopper 305. The outer surface of the connecting rod 306 is rotatably connected to the inner wall of the fixing plate 301. A circular block 307 is fixedly connected to the rear surface of the stopper 305. The outer surface of the circular block 307 is rotatably connected to the inner wall of the fixing plate 301.

[0027] The effect achieved by the entire Embodiment 2 is that when replacing the filter screen 304, the plurality of stoppers 305 are sequentially toggled. The connecting rods 306 and the circular blocks 307 fixedly connected thereto will be rotationally limited in the inner wall of the fixing plate 301, so that when the stoppers 305 rotate to the other side or are parallel to both sides of the fixing plate 301, it is convenient to take out the filter screen 304 to be cleaned or replaced from the circular groove 303, and the practicability is high.

[0028] Working principle: When the protection device of the low-voltage power supply for network engineering is in use, the low-voltage power supply is fixedly arranged at the inner bottom of the protection shell 1. Then, the two fixing frames 201 are respectively placed into the two square grooves 5 in the correct direction in sequence. Next, the two fixing plates 301 are respectively attached to the front surfaces of the two fixing frames 201. A plurality of matching wing bolts 302 are sequentially inserted through the fixing plates 301 and the fixing frames 201, and the wing bolts 302 are manually rotated so that they are threadedly connected to the protection shell 1 during the rotation process, thereby driving the fixing plates 301 to press the fixing frames 201 and fixing them to the front side of the protection shell 1. Synchronously start the two motors 203 fixed to the rear sides of the support frames 202. When the output ends of the motors 203 drive the rotating rods 204 to rotate, the plurality of fan blades 205 fixedly arranged on their surfaces rotate synchronously. Under the high-speed rotation of the two groups of a plurality of fan blades 205, external air will be pumped into the protection shell 1. When the external air penetrates the filter screen 304, the dust and impurities in the air will be filtered and then enter the protection shell 1 and blow the surface of the low-voltage power supply. Under the action of the high-speed air flow, the high-temperature gas in the protection shell 1 will quickly discharge from the plurality of heat dissipation holes 4, effectively avoiding the heat accumulation inside the protection shell 1 and improving the heat dissipation effect inside the protection shell 1. When replacing the filter screen 304, a plurality of stoppers 305 are sequentially toggled, and the connecting rod 306 and the circular block 307 fixedly connected to them will be rotationally limited in the inner wall of the fixing plate 301, so that when the stopper 305 rotates to the other side or is parallel to both sides of the fixing plate 301, it is convenient to take out the filter screen 304 to be cleaned or replaced from the circular groove 303, and the practicability is high.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
