Description

Technical Field

[0001] The utility model relates to the technical field of safe power supplies, in particular to an overload-proof safe power supply for industrial control computers. Background Art

[0002] An overload-protected power supply for industrial computers is a power supply specifically designed for industrial control computers. It features overload protection. However, existing overload-protected power supplies for industrial computers suffer from several significant drawbacks. First, their temperature monitoring mechanisms are insensitive. When the power supply's temperature exceeds the safe range, they fail to issue timely alarms and initiate effective measures. This increases the risk of equipment damage from overheating, posing a potential threat to the stable operation of industrial control systems. Second, their overload protection features are relatively limited and slow to respond. Traditional fuses or circuit breakers, as the primary overload protection, operate slowly, and once blown or disconnected, they require manual replacement or resetting. This not only impacts continuous operation but also increases maintenance costs and workload. Furthermore, poor heat dissipation and dustproofing are also major drawbacks of older equipment. Due to the lack of efficient heat dissipation mechanisms and dustproofing, dust easily accumulates over long-term operation, resulting in reduced heat dissipation and, in turn, overheating and performance degradation. This not only shortens the equipment's lifespan but can also negatively impact the overall performance of industrial control systems.

[0003] For this reason, we propose an overload-proof safety power supply for industrial computers. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figures 1-4 A safety power supply with an overload protection for industrial computers includes a power supply body 1, with a connector 2 and an external cable 19 installed at both ends of the power supply body 1, a rotating motor 5 is installed inside the power supply body 1, and a first screw rod 6 is installed at the output end of the rotating motor 5. A limited straight shaft 8 is fixedly connected to the inside of the power supply body 1, and a sliding circular plate 9 is movably sleeved on the first screw rod 6 and the limited straight shaft 8. Two symmetrically arranged push rods 10 are fixedly connected to one side of the sliding circular plate 9.

[0021] A worm 7 is fixedly sleeved on the outer periphery of the first screw rod 6, and a follower shaft 11 is rotatably installed inside the power supply body 1. A worm gear 12 is fixedly sleeved on the outer periphery of the follower shaft 11, and the worm 7 is engaged with the worm gear 12. A bidirectional screw rod 13 is provided on the follower shaft 11. A limiting straight rod 15 is fixedly connected to the inside of the power supply body 1, and four symmetrically arranged limiting sliding blocks 14 are movably sleeved on the bidirectional screw rod 13 and the limiting straight shaft 8. One end of the two limiting sliding blocks 14 on the same side are fixedly connected to a closing shell 16.

[0022] Two symmetrically arranged axial flow fans 17 are installed inside the power supply body 1 , and two symmetrically arranged filters 18 are fixedly connected to both ends of the power supply body 1 .

[0023] A backup power supply 3 , a temperature sensor 4 and a warning light 20 are installed on one side of the power supply body 1 .

[0024] A through slot is formed inside the connector 2 , and the push rod 10 passes through the through slot.

[0025] One side of the closed shell 16 is provided with two symmetrically arranged semicircular grooves, which fit with the top rod 10 , and the other side of the closed shell 16 is provided with a semicircular card groove, which fits with the external cable 19 .

[0026] Working principle: During the use of the device, when the temperature sensor 4 detects that the temperature of the power supply body 1 (the safe temperature of the power supply body 1 is 0℃-50℃, and here it is higher than 50 degrees) is abnormal, the built-in controller of the power supply body 1 will flash the warning light 20, and the motor 5 will be turned on. The turning on of the motor 5 causes the first screw 6 to rotate, and the rotation of the first screw 6 simultaneously drives the worm 7 to rotate and the sliding circular plate 9 to slide. During the sliding of the sliding circular plate 9, there is a push rod 10 to limit its sliding. The sliding circular plate 9 continues to slide, so that the push rod 10 on the sliding circular plate 9 will push out the external connector connected to the connector 2, so that the power supply body 1 is disconnected from the external The connector is separated, and when the worm 7 rotates, it drives the worm wheel 12 to rotate by meshing with the worm wheel 12. The rotation of the worm wheel 12 causes the bidirectional screw 13 to rotate. The rotation of the bidirectional screw 13 drives the two limiting sliding blocks 14 thereon to move toward the power supply body 1. During the movement of the sliding limiting blocks toward the power supply body 1, the two closing shells 16 are driven to close the outer wall of the power supply body 1. In the process of closing the power supply body 1, the closing shell 16 is closed by two other limiting sliding blocks 14 and a limiting straight rod 15 for sliding limit. By separating from the external connector and protecting the power supply body 1, the safety of the power supply body 1 can be improved.

[0027] Furthermore, during the use of the device, the two sides of the power supply body 1 can be cooled by the rotation of the two axial flow fans 17. While cooling, the filter 18 intercepts external dust. After the power supply body 1 is disconnected from the external connector and the temperature drops to a safe temperature, the rotating motor 5 is turned on and reversed, so that the enclosed shell 16 leaves the power supply body 1. At this time, the power supply used by the device is the backup power supply 3.
