Description

Technical Field

[0001] This utility model relates to the field of power electronics technology, and in particular to a high-reliability commutation power supply device. Background Technology

[0002] A high-reliability commutation power supply unit is a device focused on ensuring stable power switching and efficient supply. Through a precisely designed circuit structure and intelligent control module, it can quickly and accurately switch between different power modes or power supply circuits, avoiding disruptions to equipment operation due to power outages or surges during power switching. The unit employs multiple redundancy backups and fault detection mechanisms, enabling real-time monitoring of the power supply status. When the main power supply experiences anomalies, such as voltage fluctuations, short circuits, or overloads, it quickly and reliably switches to the backup power supply, ensuring a continuous and stable power supply to the load.

[0003] When the device is in use, the internal power supply will generate high temperatures, so heat dissipation is required. If the humidity in the air is high during heat dissipation, the moisture in the air will enter the device along with the air, which may cause a short circuit in the internal circuit of the device. Utility Model Content

[0004] The purpose of this invention is to provide a highly reliable commutation power supply device to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-reliability commutation power supply device, including a power supply box, and further comprising:

[0006] A dehumidification mechanism is provided on the power supply box. The dehumidification mechanism includes a cylinder on the power supply box. The dehumidification mechanism is used to remove moisture from the air during the heat dissipation process of the device to prevent moisture from entering the device and causing a short circuit.

[0007] A pressure relief mechanism is provided inside the power supply box. The pressure relief mechanism includes a rectangular box mounted on the power supply box. The pressure relief mechanism is used to effectively expel air when the device is dissipating heat, and at the same time, to relieve the air pressure inside the device.

[0008] Preferably, the dehumidification mechanism includes a cylinder fixedly installed inside the power supply box, a reciprocating threaded rod rotatably installed through the cylinder, a drive motor fixedly installed on the left side of the cylinder, the output shaft of the drive motor being fixedly connected to the reciprocating threaded rod, and a plurality of cooling fan blades fixedly installed on the reciprocating threaded rod.

[0009] Preferably, the reciprocating threaded rod is threaded with an internal threaded plate, and two limiting slide rods are fixedly installed on the outer wall of the internal threaded plate. Two limiting slide grooves are opened inside the cylinder, and the ends of the two limiting slide rods that are far apart from each other extend into the two limiting slide grooves and are slidably connected to the two limiting slide grooves respectively.

[0010] Preferably, two C-shaped plates are fixedly installed on the left side of the internal thread plate, and two extrusion rollers are rotatably installed inside the two C-shaped plates respectively.

[0011] Preferably, a filter plate is fixedly installed on the reciprocating threaded rod, an absorbent sponge is fixedly installed on the right side of the filter plate, a collection tube is fixedly installed inside the cylinder, the bottom end of the collection tube extends to the outside of the power supply box, and a rectangular plug is provided at the bottom of the collection tube.

[0012] Preferably, the pressure relief mechanism includes a rectangular box fixedly installed on the left side of the power supply box, the left end of the rectangular box extending outside the power supply box, and a plurality of circular holes opened on the right side of the rectangular box.

[0013] Preferably, a T-shaped hollow block is slidably installed inside the rectangular box, a limit spring is fixedly installed on the left inner wall of the T-shaped hollow block, the right end of the limit spring is fixedly connected to the right inner wall of the rectangular box, and rectangular grooves are fixedly installed on the front and back of the T-shaped hollow block respectively.

[0014] Preferably, a circular dust cover is fixedly installed on the right side of the power supply box, the right end of the reciprocating threaded rod rotates through the circular dust cover, a cleaning block is fixedly installed on the reciprocating threaded rod, and the left side of the cleaning block contacts the circular dust cover.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model:

[0017] 1. When in use, start the drive motor. The drive motor drives the reciprocating screw rod to rotate, which in turn drives several cooling fan blades to rotate. The cooling fan blades generate suction force, which draws outside air into the cylinder through the circular dust cover. The rotation of the reciprocating screw rod also drives the cleaning block to rotate, cleaning dust from the surface of the circular dust cover to prevent dust from clogging the holes and affecting the normal suction effect. As the air passes through the absorbent sponge, it filters out moisture. The filtered air then passes through the filter plate into the power supply box. The rotation of the reciprocating screw rod... The reciprocating internal thread plate drives the C-shaped plate to move. As the C-shaped plate moves closer to the absorbent sponge, it drives the squeezing roller to move. Since the reciprocating threaded rod drives the filter plate and the absorbent sponge to rotate synchronously, when the squeezing roller contacts the absorbent sponge, the rotation of the absorbent sponge will cause the squeezing roller to rotate and squeeze the absorbent sponge, expelling the filtered water from the absorbent sponge. This allows the absorbent sponge to continuously absorb water and maintain the dehumidification effect. The squeezed-out water will enter the collection pipe along the inner wall of the power supply box and be collected. When there is too much water, the rectangular plug can be opened to drain the water.

[0018] 2. As more and more air enters the power supply box, the air pressure inside the power supply box will gradually increase. The gas will enter the rectangular box through the round hole, and the gas will push the T-shaped hollow block to move away from the power supply box. The corresponding limit spring will be stretched and deformed. When the T-shaped hollow block drives the rectangular slot away from the rectangular box, the air inside the rectangular box will be discharged from the rectangular slot, thereby relieving the pressure of the power supply box. As the gas inside the power supply box is discharged, the heat inside the power supply box will also be discharged with the air, thereby achieving the effect of heat dissipation.

[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] This utility model provides, for example Figure 1-5 The high-reliability commutation power supply device shown includes a power supply box 1 and further includes: a dehumidification mechanism, which is mounted on the power supply box 1 and includes a cylinder 101 mounted on the power supply box 1. The dehumidification mechanism is used to remove moisture from the air during the heat dissipation process of the device, preventing moisture from entering the device and causing a short circuit; and a pressure relief mechanism, which is mounted inside the power supply box 1 and includes a rectangular box 2 mounted on the power supply box 1. The pressure relief mechanism is used to effectively expel air during the heat dissipation process of the device and simultaneously relieve the air pressure inside the device. The dehumidification mechanism includes a cylinder 101 fixedly installed inside the power supply box 1. A reciprocating threaded rod 102 is rotatably mounted through the cylinder 101. A drive motor 103 is fixedly mounted on the left side of the cylinder 101. The output shaft of the drive motor 103 is fixedly connected to the reciprocating threaded rod 102. Several cooling fan blades 104 are fixedly mounted on the reciprocating threaded rod 102. A reciprocating threaded rod 102 is threaded with an internal threaded plate 105. Two limiting slide rods 106 are fixedly installed on the outer wall of the internal threaded plate 105. Two limiting slide grooves 107 are opened inside the cylinder 101. The ends of the two limiting slide rods 106 that are far apart from each other extend into the two limiting slide grooves 107 and are slidably connected to the two limiting slide grooves 107 respectively. Two C-shaped plates 108 are fixedly installed on the left side of the internal threaded plate 105. Two extrusion rollers 109 are rotatably installed in the two C-shaped plates 108 respectively. A filter plate 110 is fixedly installed on the reciprocating threaded rod 102. A water-absorbing sponge 111 is fixedly installed on the right side of the filter plate 110. A collection pipe 112 is fixedly installed inside the cylinder 101. The bottom end of the collection pipe 112 extends to the outside of the power supply box 1. A rectangular plug 113 is provided at the bottom of the collection pipe 112.

[0027] When in use, the drive motor 103 is started, which drives the reciprocating threaded rod 102 to rotate. The reciprocating threaded rod 102 drives several cooling fan blades 104 to rotate, generating suction force. The suction force draws outside air into the cylinder 101 through the circular dust cover 205. When the reciprocating threaded rod 102 rotates, it also drives the cleaning block 206 to rotate, which cleans the dust on the surface of the circular dust cover 205, preventing dust from clogging the holes on the circular dust cover 205 and affecting the normal suction effect. When the air passes through the water-absorbing sponge 111, it filters out the moisture in the air. The filtered air then enters the power supply box 1 through the filter plate 110. When the reciprocating threaded rod 102 rotates, it drives the internal thread... The reciprocating movement of plate 105 causes the internally threaded plate 105 to drive the C-shaped plate 108 to move. As the C-shaped plate 108 moves closer to the absorbent sponge 111, it drives the squeezing roller 109 to move. Since the reciprocating threaded rod 102 drives the filter plate 110 and the absorbent sponge 111 to rotate synchronously, when the squeezing roller 109 contacts the absorbent sponge 111, the rotation of the absorbent sponge 111 will cause the squeezing roller 109 to rotate and squeeze the absorbent sponge 111 comprehensively, thus expelling the water filtered inside the absorbent sponge 111. This allows the absorbent sponge 111 to continuously absorb water and maintain the dehumidification effect. The water squeezed out will enter the collection pipe 112 along the inner wall of the power supply box 1 and be collected. When there is too much water, the rectangular plug 113 can be opened to drain the water.

[0028] The pressure relief mechanism includes a rectangular box 2 fixedly installed on the left side of the power supply box 1. The left end of the rectangular box 2 extends outside the power supply box 1, and several circular holes 201 are opened on the right side of the rectangular box 2. A T-shaped hollow block 202 is slidably installed inside the rectangular box 2. A limit spring 203 is fixedly installed on the left inner wall of the T-shaped hollow block 202, and the right end of the limit spring 203 is fixedly connected to the right inner wall of the rectangular box 2. Rectangular grooves 204 are fixedly installed on the front and back of the T-shaped hollow block 202, respectively. A circular dust cover 205 is fixedly installed on the right side of the power supply box 1. The right end of the reciprocating threaded rod 102 rotates through the circular dust cover 205. A cleaning block 206 is fixedly installed on the reciprocating threaded rod 102, and the left side of the cleaning block 206 contacts the circular dust cover 205.

[0029] As more and more air enters the power supply box 1, the air pressure inside the power supply box 1 gradually increases. The gas enters the rectangular box 2 through the round hole 201. The gas pushes the T-shaped hollow block 202 to move away from the power supply box 1. The corresponding limiting spring 203 will be stretched and deformed. When the T-shaped hollow block 202 drives the rectangular groove 204 away from the rectangular box 2, the air inside the rectangular box 2 will be discharged from the rectangular groove 204, thereby relieving the pressure in the power supply box 1. As the gas in the power supply box 1 is discharged, the heat inside the power supply box 1 will also be discharged with the air, thereby achieving the effect of heat dissipation.

[0030] The working principle of the high-reliability commutation power supply device provided by this utility model is as follows:

[0031] When in use, the drive motor 103 is started, which drives the reciprocating threaded rod 102 to rotate. The reciprocating threaded rod 102 drives several cooling fan blades 104 to rotate, generating suction force. The suction force draws outside air into the cylinder 101 through the circular dust cover 205. When the reciprocating threaded rod 102 rotates, it also drives the cleaning block 206 to rotate, which cleans the dust on the surface of the circular dust cover 205, preventing dust from clogging the holes on the circular dust cover 205 and affecting the normal suction effect. When the air passes through the water-absorbing sponge 111, it filters out the moisture in the air. The filtered air then enters the power supply box 1 through the filter plate 110. When the reciprocating threaded rod 102 rotates, it drives the internal thread... The reciprocating movement of plate 105 causes the internal thread plate 105 to drive the C-shaped plate 108 to move. When the C-shaped plate 108 moves closer to the absorbent sponge 111, it drives the squeezing roller 109 to move. Since the reciprocating threaded rod 102 drives the filter plate 110 and the absorbent sponge 111 to rotate synchronously, when the squeezing roller 109 contacts the absorbent sponge 111, the rotation of the absorbent sponge 111 will cause the squeezing roller 109 to rotate and squeeze the absorbent sponge 111 in a comprehensive manner, thus expelling the water filtered inside the absorbent sponge 111. This allows the absorbent sponge 111 to continuously absorb water and maintain the dehumidification effect. The water squeezed out will enter the collection pipe 112 along the inner wall of the power supply box 1 and be collected. When there is too much water, the rectangular plug 113 can be opened to drain the water.

[0032] As more and more air enters the power supply box 1, the air pressure inside the power supply box 1 gradually increases. The gas enters the rectangular box 2 through the round hole 201. The gas pushes the T-shaped hollow block 202 to move away from the power supply box 1. The corresponding limiting spring 203 will be stretched and deformed. When the T-shaped hollow block 202 drives the rectangular groove 204 away from the rectangular box 2, the air inside the rectangular box 2 will be discharged from the rectangular groove 204, thereby relieving the pressure in the power supply box 1. As the gas in the power supply box 1 is discharged, the heat inside the power supply box 1 will also be discharged with the air, thereby achieving the effect of heat dissipation.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
