Detailed implementation manners

[0020] The following further describes the present application in detail with reference to the accompanying drawings.

[0021] The embodiment of the present application discloses a modular UPS emergency power supply.

[0022] Referring to Figure 1 and Figure 2 , the modular UPS emergency power supply includes a cabinet 1 and a plurality of battery boxes 2 installed in the cabinet 1. A mounting frame 3 is fixedly installed on the inner side wall of the cabinet 1. Each battery box 2 is arranged at intervals in sequence along the height direction of the mounting frame 3, and the battery box 2 is slidably arranged on the mounting frame 3 in the horizontal direction. One side of the battery box 2 close to the cabinet door of the cabinet 1 is fixedly fastened to the mounting frame 3 by bolts. Two grips 20 facing the cabinet door are fixedly installed on the outer side wall of the battery box 2, and through the grips 20, it is convenient for maintenance personnel to remove the battery box 2 from the mounting frame 3.

[0023] As shown in Figure 2 and Figure 3 , a sliding frame 4 is further arranged in the cabinet 1. The sliding frame 4 is movably arranged in the cabinet 1 along the sliding direction of the battery box 2 on the mounting frame 3. The sliding frame 4 includes a plurality of placing plates 40 arranged at intervals in sequence along the height direction of the cabinet 1. Each placing plate 40 is parallel to each other, and the upper part of the placing plate 40 is used to carry the corresponding battery box 2. The placing plate 40 is slidably arranged between two adjacent battery boxes 2 in the horizontal direction. One side of the sliding frame 4 away from the cabinet door is limited in the cabinet 1, and two lifting rods 41 are arranged to lift and lower in the vertical direction on one side of the sliding frame 4 facing the cabinet door. The lifting rods 41 are symmetrically arranged on the left and right sides of the sliding frame 4, and the installation positions of the lifting rods 41 are close to the bottom of the sliding frame 4.

[0024] As shown in Figure 2 and Figure 3As shown, the lifting rod 41 is used to support one side of the sliding frame 4 that has been moved out of the cabinet body 1. A fastener 42 for screwing and fixing the lifting rod 41 onto the sliding frame 4 is threadedly connected to the sliding frame 4. In this embodiment, the fastener 42 is a bolt. The screwing direction of the fastener 42 is perpendicular to the lifting direction of the lifting rod 41.

[0025] As Figure 2 , Figure 3 shown, a first support wheel 43 is also rotatably provided at the bottom of the lifting rod 41. After the sliding frame 4 is moved out of the cabinet body 1, by adjusting the height of the first support wheel 43 to contact the ground, at this time, the first support wheel 43 can support one side of the sliding frame 4 that has been moved out of the cabinet body 1. In addition, the sliding frame 4 can be conveniently slid through the first support wheel 43.

[0026] As Figure 2 , Figure 3 shown, a return spring 45 is sleeved outside the lifting rod 41, and the return spring 45 expands and contracts along the lifting direction of the lifting rod 41. One end of the return spring 45 abuts against the sliding frame 4, and the other end of the return spring 45 is used to push the first support wheel 43 away from the sliding frame 4. After the lifting rod 41 is moved out of the cabinet body 1, by releasing the locking of the lifting rod 41 by the fastener 42, at this time, the first support wheel 43 will quickly contact the ground under the combined action of the elastic force of the return spring 45 and its own gravity. Finally, the lifting rod 41 is locked again by the fastener 42, and at this time, the lifting rod 41 can support the sliding frame 4.

[0027] As Figure 2 , Figure 3 shown, a lifting rod 6 is fixedly installed on the lifting rod 41. The lifting rod 6 is located on the side of the first support wheel 43 facing the cabinet door. Through the lifting rod 6, it is convenient for maintenance personnel to lift the lifting rod 41 upward. As the height of the lifting rod 41 continuously rises, at this time, the return spring 45 will be gradually compressed and store energy.

[0028] As Figure 2 , Figure 3 shown, a limiting plate 46 is fixedly installed on the outer side wall of the top of the lifting rod 41 away from the first support wheel 43. The width of the limiting plate 46 is greater than the diameter of the lifting rod 41. The limiting plate 46 is polygonal, and one side of the limiting plate 46 is attached to the outer side wall of the sliding frame 4. When the lifting rod 41 moves downward, the limiting plate 46 can limit the maximum descending height of the lifting rod 41, thereby effectively preventing the situation that the lifting rod 41 detaches from the sliding frame 4. In addition, under the guidance of the limiting plate 46, it is possible to prevent the lifting rod 41 from rotating on the sliding frame 4, thereby ensuring that the first support wheel 43 moves along a specified path.

[0029] As Figure 2 , Figure 3As shown in the figure, two second support wheels 44 located inside the cabinet 1 are also rotatably arranged on the sliding frame 4. The second support wheels 44 are symmetrically arranged on the left and right sides of the sliding frame 4, and the first support wheel 43 and the second support wheel 44 are respectively located on the front and rear sides of the sliding frame 4. The second support wheel 44 is placed on the inner bottom wall of the cabinet 1. The second support wheel 44 can not only support the sliding frame 4, but also ensure that the sliding frame 4 slides more smoothly in the cabinet 1.

[0030] As Figure 2 , Figure 3 shown in the figure, two groups of slide bars 5 are fixedly installed on the sliding frame 4. The two groups of slide bars 5 are symmetrically arranged on the left and right sides of the sliding frame 4. Each slide bar 5 in the same group is arranged at intervals in the height direction of the sliding frame 4. Each slide bar 5 is parallel to each other, and the length of the slide bar 5 extends along the sliding direction of the sliding frame 4 in the cabinet 1. A plurality of limiting tubes 10 corresponding to the slide bars 5 one by one are fixedly installed on the inner side wall of the cabinet 1. The slide bars 5 are respectively movably inserted into their corresponding limiting tubes 10.

[0031] Through the mutual cooperation of the slide bar 5 and the limiting tube 10, on the one hand, it can ensure that the sliding frame 4 moves along the specified path, improving the stability of the sliding frame 4 during sliding. On the other hand, when the sliding frame 4 is removed from the cabinet 1, under the limitation of the limiting tube 10, it can prevent the other side of the sliding frame 4 from completely detaching from the cabinet 1, achieving the purpose of limiting the sliding frame 4.

[0032] The implementation principle is as follows: When the circuit or battery pack of the battery box 2 needs to be maintained, first move one side of the sliding frame 4 out of the cabinet 1, and then release the locking of the lifting rod 41 by the fastener 42. At this time, the lifting rod 41 will push the first support wheel 43 to support on the ground under the elastic force of the return spring 45. Then lock the lifting rod 41 again through the fastener 42. At this time, the battery box 2 to be maintained on the mounting frame 3 can be moved to the placement plate 40 at the specified height. By moving the battery box 2 out of the cabinet 1, the inconvenience brought by the narrow space in the cabinet 1 to the maintenance work is greatly reduced, ensuring the smooth progress of the maintenance work; improving the maintenance efficiency, shortening the maintenance cycle, and facilitating the maintenance of the battery box 2.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
