Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an uninterruptible power supply system for a main ventilation fan in a mine area. Background Art

[0002] An uninterruptible power supply system usually consists of multiple UPS cabinets. A UPS cabinet, or uninterruptible power supply, is a power protection device that contains an energy storage device, uses an inverter as the main component, and has a stable voltage and frequency output. It is mainly used to provide uninterruptible power supply to a single computer, computer network system, or other power electronic equipment.

[0003] Generally, a UPS cabinet is connected to a device that needs power supply through a power supply line to supply power to it. Under normal circumstances, in order to ensure the stability of the power supply process and prevent the power supply line from loosening or falling off from the power socket of the UPS cabinet, the power supply line is usually connected to the power socket by screw connection to ensure stability. However, the main ventilation fan in the applicant's production mine has a large power, and the diameter and weight of the power supply line used are greater than conventional power supply lines. The power supply line will age due to long-term use or improper connection, which will cause it to loosen or fall off from the power socket of the UPS cabinet due to its own gravity, which will cause the equipment to lose power and affect the production process. In order to ensure the stability of its connection, a technical solution such as Reference 1 has appeared in the prior art.

[0005] Reference 1: A UPS uninterruptible power supply system is disclosed, including an electric control mechanism and a branch mechanism. The branch mechanism is fixed on the electric control mechanism. The power line connecting the UPS power supply box and the power user is inserted into the power supply interface to achieve the connection between the UPS power supply box and the power user. When the height difference between the power interface and the power user is large, the outer frame is pushed by manpower to move the outer frame up and down inside the movable groove to a suitable position. The wire rack plate supports the power line, effectively preventing the power line from loosening or the interface from being damaged due to the height difference, and ensuring the continuous effectiveness and stability of the power supply process. The wire rack plate of the device supports the power line by setting a card-mounted wire rack plate with a card slot. The card slot specifications on the card-mounted wire rack plate cannot be changed, and can only support fixed-specification power lines. If the power line does not meet the specifications of the wire rack plate, it is easy to fall off the wire rack plate. Utility Model Content

[0020] The following will be combined with the attached embodiment of the utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0021] Example 1

[0022] like Figure 1-2 As shown, the utility model provides an uninterruptible power supply system for the main ventilation fan in the mine area, including multiple UPS cabinets, and the multiple UPS cabinets are connected in parallel by adopting the existing UPS parallel redundancy technology to ensure the power supply to the main ventilation fan in the mine area. In order to ensure the stability of the power supply, the UPS cabinet in this embodiment can support the connection end where the power supply line is connected to the power supply interface 3 of the UPS cabinet to avoid loosening and falling off, thereby ensuring the power supply to the main ventilation fan in the mine area. The UPS cabinet is similar to the prior art in that both include a cabinet 1 and an electric control mechanism arranged inside the cabinet 1, and the outer wall of the cabinet 1 is provided with multiple power supply interfaces 3 electrically connected to the electric control mechanism. The main ventilation fan in the mine area is electrically connected to the power supply interface 3 through the power supply line so that the main ventilation fan in the mine area can be powered.

[0023] The difference between the present invention and the prior art is that a buffer mechanism is provided above the power supply interface 3, which can lift the end of the power supply line connected to the power supply interface 3 to raise it to a horizontal position higher than the power supply interface 3. The buffer mechanism is responsible for bearing the gravity of the falling power line, and the buffer mechanism reduces the downward pressure of the power line due to its own gravity, thereby preventing the power line from loosening or falling off from the power supply interface 3 of the UPS cabinet due to its own gravity.

[0024] In this embodiment, the buffer mechanism includes a hanging rope 4 made of soft plastic material and a hook 5 fixedly arranged on the outer wall of the cabinet 1. The hook 5 is a common hanging hook in the prior art. The hook 5 is fixedly welded on the outer wall of the cabinet 1 located above the corresponding power supply interface 3. The hanging rope 4 includes a rope body 401, a hanging portion 402 arranged at one end of the rope body 401, and a ring portion 403 arranged at the other end of the rope body 401. The ring portion 403 is a common hanging ring that can be hung on the hook 5. In normal use, the hanging portion 402 can carry part of the rope body 401 through the ring portion 403 and hang on the hook 5. After the hanging portion 402 passes through the ring portion 403, a fixed space that can be used to tighten the power line can be formed between the ring portion 403 and the rope body 401. When the power line is inserted in the fixed space, the hanging rope 4 and the hook 5 cooperate to support the power line to prevent the power line from falling off the hanging rope 4, and the power line is always supported. At the same time, the fixed space can automatically change according to the thickness of the power supply line, so as to support power supply lines of different specifications.

[0025] The above is a basic implementation method of the utility model, and further improvements, optimizations and limitations can be made on the above basis to obtain the following embodiments:

In this embodiment, the hook portion 402 is hooked with the hook portion 501, and because the thickness of the power line is different, after the power lines of different specifications are tightened, the length of the hanging rope 4 also changes. By hanging with the hook portions 501 of different heights, the length change of the hanging rope 4 is adapted to avoid the situation that the hanging rope 4 corresponding to the specifications is required to support the power lines of different specifications.

[0028] In this embodiment, in order to fix the fixing part 502, a fixing stud is welded on the outer wall of the cabinet 1, and a through hole for the fixing stud to pass through is provided on the fixing part 502. The fixing stud passes through the through hole and is screwed to the nut.
