Description

Technical Field

[0001] The utility model relates to the technical field of UPS, and specifically relates to a high-reliability UPS module. Background Technique

[0002] The UPS module is an important part of the UPS power supply. It is an electronic device used to provide reliable power supply during power interruption or voltage fluctuation. The UPS module usually consists of one or more inverters, and each inverter can carry one or more loads.

[0003] The existing UPS modules have the following problems in the power supply connection of the power plant UPS DC power supply in the market: when the cable is connected to the UPS DC power supply, the joint connection is prone to looseness under stress, resulting in poor contact and potential safety hazards, which is not conducive to the safe use of users. In the prior art, the patent number is CN217956662U, and its name is a device for improving the power supply reliability of the power plant UPS DC power supply. By using a limiting module to limit the cable, when the external cable is connected to the UPS, the cable is fixed by the cooperation of the limiting module and the adjustable positioning module, ensuring that the connection between the cable and the UPS will not loosen during the pulling process, solving the problem that the joint connection of the existing cable and the UPS is prone to looseness under stress, resulting in poor contact and potential safety hazards, thus solving the above problems.

[0004] However, when using such a UPS module, since a large amount of heat is generated during the operation of the UPS module itself, each UPS module is provided with heat dissipation through holes and a heat dissipation module. In order to prevent dust from entering the interior of the device, which may cause the device to short-circuit itself, a dust filter plate is required to isolate the heat dissipation through holes to adsorb dust in the air and prevent it from entering the interior of the device. As the usage time increases, more and more dust is adsorbed on the filter plate, which will affect the heat dissipation efficiency of the device itself. Therefore, it is necessary to regularly remove the filter plate from the interior of the device and clean the dust, which is a rather cumbersome operation; therefore, it does not meet the existing requirements, and for this reason, we propose a high-reliability UPS module. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a highly reliable UPS module to solve the problems proposed in the above background technology. When using such a UPS module, a large amount of heat is generated during the operation of the UPS module itself. Therefore, each UPS module is provided with heat dissipation through holes and a heat dissipation module. In order to prevent dust from entering the interior of the device, which may cause the device to short-circuit itself, a dust filter plate is required to isolate the heat dissipation through holes to adsorb dust in the air and prevent it from entering the interior of the device.

Therefore, the filter plate needs to be regularly removed from the interior of the device and cleaned of its dust, and this operation is rather cumbersome, etc.

[0006] To achieve the above object, the present utility model provides the following technical solution: a highly reliable UPS module, including a UPS module, on both sides of the outer surface of the UPS module, a metal shell is fixedly provided, and on the outer surface of the metal shell, a plurality of heat dissipation through holes are provided which all penetrate the metal shell and communicate with the interior of the UPS module;

[0014] 1. By means of the timing stepper motor, the present utility model can automatically move the filter screen out of the interior of the metal shell to the outside of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] The UPS module 1 (model number MDR20 - 200K), timing stepper motor 7 (model number 200V) and circular cleaning head 17 (model number ER11 - KI3) mentioned in the present utility model can all be obtained by purchasing from the market or customizing privately.

[0021] Please refer to Figures 1 to 3, An embodiment provided by the present utility model: A highly reliable UPS module, including a UPS module 1, two metal shells 2 are fixedly provided on both sides of the outer surface of the UPS module 1, and a plurality of heat dissipation through holes are provided on the outer surface of the metal shell 2, which penetrate through the metal shell 2 and communicate with the inside of the UPS module 1;

[0022] A filter screen 3 is provided inside the metal shell 2, and the upper end surface of the filter screen 3 is connected to an automatic cleaning mechanism installed inside the metal shell 2.

[0023] The automatic cleaning mechanism includes a timing stepper motor 7. The output shaft of the timing stepper motor 7 is connected to a transmission rotating shaft 6 through a coupling. One end of the transmission rotating shaft 6 is connected to a threaded rod 4. The outer surface of the threaded rod 4 is sleeved with an internal thread sleeve 5 fixed to the filter screen 3; When it is necessary to clean the filter screen 3, start the timing stepper motor 7, and the threaded rod 4 connected to it through the transmission rotating shaft 6 can be driven to rotate. Since the internal thread sleeve 5 sleeved on the outer surface of the threaded rod 4 is fixed to the filter screen 3, the internal thread sleeve 5 itself cannot rotate. When the threaded rod 4 rotates, through the transmission of the thread structure, the internal thread sleeve 5 will move back and forth on the outer surface of the threaded rod 4, and the filter screen 3 fixed to it will also move accordingly during the movement of the internal thread sleeve 5.

[0024] A guide rod fixed inside the metal shell 2 is provided below the filter screen 3, and a guide sleeve fixed to the filter screen 3 is movably sleeved on one side of the outer surface of the guide rod; The smoothness of the movement of the filter screen 3 can be ensured through the guide sleeve.

[0025] A synchronous sprocket A8 is fixedly sleeved on the outer surface of the transmission rotating shaft 6. There is a synchronous sprocket B9 on both sides of the synchronous sprocket A8. The two synchronous sprockets B9 and a synchronous sprocket A8 are connected in series through a synchronous chain 10, and the axis of the synchronous sprocket B9 is connected to a short rotating shaft; When the transmission rotating shaft 6 rotates, the synchronous sprocket A8 fixedly sleeved on the outer surface of the transmission rotating shaft 6 and the two synchronous sprockets B9 connected in series with the synchronous sprocket A8 through the synchronous chain 10 will rotate synchronously. When the synchronous sprocket B9 rotates, the short rotating shaft connected to its axis will also rotate.

[0026] One side of the outer surface of the short rotating shaft is fixedly sleeved with the bevel gear A11. The bevel gear A11 meshes with the bevel gear B12. The axis of the bevel gear B12 is connected with a long rotating shaft 13. The outer surface of the long rotating shaft 13 is fixedly sleeved with a plurality of bevel gears C14 from top to bottom in sequence. The bevel gear C14 meshes with the bevel gear D15. The axis of the bevel gear D15 is connected with a rotating shaft 16. The surface of the rotating shaft 16 facing the filter net 3 is fixedly connected with a circular cleaning head 17. When the short rotating shaft rotates, the bevel gear A11 fixedly sleeved on the outer surface of the short rotating shaft and the bevel gear B12 meshing with the bevel gear A11 will also rotate accordingly. When the bevel gear B12 rotates, the long rotating shaft 13 connected to the axis of the bevel gear B12 and the bevel gear C14 fixedly sleeved on the outer surface of the long rotating shaft 13 will also rotate accordingly. When the bevel gear C14 rotates, the bevel gear D15 meshing with it and the rotating shaft 16 connected to the axis of the bevel gear D15 will also rotate accordingly. When the rotating shaft 16 rotates, the circular cleaning head 17 fixedly connected to it will also rotate accordingly. The filter net 3 leaving the inside of the metal shell 2 will contact the rotating circular cleaning head 17. Through the rotating circular cleaning head 17, the outer surface of the filter net 3 can be automatically cleaned. And by setting the timing stepper motor 7, it can be started regularly to automatically clean the filter net 3. Through the above technical solution, it is no longer necessary to clean the filter net manually regularly, which can prevent the situation that the temperature of the equipment itself becomes higher and higher due to the blockage of the filter net and the failure to clean the filter net in time, resulting in its own failure, and improves the reliability of the equipment during long-term operation;

[0027] After the cleaning is completed, the stepper motor 7 drives the transmission rotating shaft 6 connected to it to rotate in the reverse direction to re-collect the filter net 3 into the inside of the metal shell 2.

[0028] Above the transmission rotating shaft 6, there is a strip-shaped cover plate on the outer surface of the metal shell 2, and the metal shell 2 and the strip-shaped cover plate are fixed by screws; through the strip-shaped cover plate, the internal structure of the metal shell 2 can be protected.
