[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an easily adjustable SVG reactive power compensation device for computer rooms, comprising:

[0026] Several machine bodies 1 with cabinet doors are arranged side by side in the computer room. Each machine body 1 has a mobile maintenance mechanism 2 at its bottom to facilitate movement of the machine body 1. A side door 3 is provided on one side of the machine body 1. A cable support mechanism 4 is provided on the back of the machine body 1 to assist in supporting the reserved cable.

[0027] The mobile maintenance mechanism 2 includes a track frame 21, a support track 22, a mounting plate 23, a slide rail groove 24, and a support wheel set 25. The track frame 21 is installed on the ground by bolts. The support track 22 is fixedly installed on both sides of the top of the track frame 21. The tops of the two mounting plates 23 are fixedly installed on the bottom of the body 1 by bolts. The support wheel set 25 at the bottom of the mounting plate 23 is set in the slide rail groove 24 at the top of the support track 22.

[0028] Specifically, by pushing the body 1 to move, the two support wheel sets 25 at the bottom of the body 1 slide in the slide rail grooves 24 at the top of the two support rails 22, making it easy to pull out the body 1 and thus making it easy to fully open the side. Since the equipment inside the body 1 is arranged compactly, it is difficult to install and maintain the accessories designed on the inside side of the body 1 by opening only through the front cabinet door. Pulling out the body 1 increases the operating space and makes the maintenance of the body 1 more convenient.

[0029] The cabinet door and side door 3 have a dual-channel design that meets the needs of front operation and side maintenance. The mobile maintenance mechanism 2 enables the smooth movement of the equipment. The track frame 21 is fixed to the ground with bolts and serves as the basic support for the entire mobile mechanism. The support track 22 is installed on both sides of the top of the track frame 21 and provides slide rail grooves 24 to guide the movement of the machine body 1.

[0030] A guide groove 5 is provided on one side of the support rail 22 for sliding of the bottom protrusion of the mounting plate 23;

[0031] Specifically, the movement of the machine body 1 will cause the bottom mounting plate to move. The bottom protrusion of the mounting plate 23 is located in the guide groove 5 on one side of the support rail 22, which provides guidance for the movement of the machine body 1. The guide groove 5 has a wrapping design for the protrusion, which suppresses the swaying of the equipment during movement. In addition, the protrusion and the guide groove 5 do not make load-bearing contact when the support wheel set 25 is not damaged.

[0032] It also includes a fixing component 6 for limiting the body 1. The fixing component 6 includes a frame 61, a limiting screw 62 and a fixing plate 63. The frame 61 is fixedly installed at the bottom of the body 1. The limiting screw 62 is threadedly installed in the frame 61. Two fixing plates 63 are provided at the top of the track frame 21. The surface of the limiting screw 62 is threadedly installed with the inner hole of the fixing plate 63. Both fixing plates 63 are welded to one side of the supporting track 22.

[0033] It is worth noting that on one side of one of the supporting guide rails, two fixing plates 63 with holes are welded. The distribution of the two fixing plates 63 is used to fix the machine body 1 in two positions, one for placement and the other for maintenance, realizing the switching between two workstations. The machine body 1 is fixed by the limit screw 62 inside the frame 61 being threaded into the hole of the fixing plate 63. Since the ground in the machine room is flat and the machine body 1 is placed flat, the pressure on the limit screw 62 is small, and it only needs to limit the machine body 1 and resist the sliding inertia force of the equipment. The screw is made of Q235 steel. Visual cues: the fixing plate 63 can be painted with colors to distinguish the hole positions (green = placement position, red = maintenance position), and the screw surface is galvanized or coated with MoS2 lubricant.

[0034] Each support rail 22 is provided with a discharge chute 7 that communicates with the slide rail groove 24. The top of the discharge chute 7 is funnel-shaped.

[0035] The discharge trough 7 is connected to the slide rail trough 24. When some debris falls into the slide rail trough 24, the debris can be discharged through the funnel-shaped discharge trough 7. The discharge trough 7 is divided into an upper funnel shape and a lower inclined trough.

[0036] The cable support mechanism 4 includes a floating plate 41, a cable support roller 42, a plate body 43, a threaded rod 44, and a transmission component 45. Both plates 43 are fixed to the surface of the machine body 1. The threaded rod 44 is rotatably installed between the two plates 43, and the inner sleeve of the floating plate 41 is threadedly installed with the threaded rod 44. The cable support roller 42 for cable support is rotatably installed on one side of the floating plate 41, and the transmission component 45 is used for the rotation of the threaded rod 44.

[0037] Furthermore, the cable extending from the machine body 1 is placed above the cable release roller, thereby raising the cable and reserving a range for cable movement adjustment to prevent damage to the cable caused by the movement of the machine body 1. Through the design of reserving the cable raising, the movement of the machine body 1 will not cause cable damage. The floating plate 41 is moved by the rotation of the threaded rod 44, and the floating plate 41 drives the height adjustment of the cable support roller 42 to achieve the raising and lowering of the cable. Through the transmission component 45, the height adjustment of the cable support roller 42 is coordinated with the movement of the machine body 1, and the ratio of the movement distance to the lifting height is 1:0.15 (that is, when the machine body is pulled out 1100mm, the cable is lowered 15mm).

[0038] The transmission component 45 includes a gear 451 and a toothed plate 452. The toothed plate 452 is fixedly installed on the surface of the track frame 21, and the lower end of the threaded rod 44 is provided with a gear 451 that meshes with the toothed plate 452.

[0039] It is worth noting that as the body 1 moves, it will drive the gear 451 to move. The gear 451 meshes with the toothed plate 452. The movement of the body 1 will drive the rotation adjustment of the threaded rod 44, thereby controlling the height adjustment of the plate 43, avoiding damage caused by pulling the cable, and also achieving the effect of lifting and resetting the cable.

[0040] The surface of the body 1 is provided with guide strips 8 for guiding the sliding of the plate 43;

[0041] Among them, the floating plate 41, with the cable support roller 42, moves in a straight line with an offset of ≤0.5mm to avoid lateral twisting of the cable. It is made of hard anodized aluminum to extend its service life.

[0042] The body 1 has a rectangular groove 9 for cable installation, and a fan 10 is embedded in one side of the body 1.

[0043] A rectangular groove 9 is provided for cables to extend from the unit 1, while a fan 10 is used to accelerate air circulation inside the unit 1. A ventilation mesh is provided at the cabinet door. The unit 1 is located in an air-conditioning room and is used to cool the room when necessary.

[0044] This device moves the machine body 1, causing the two support wheel sets 25 at the bottom of the machine body 1 to slide within the slide rail grooves 24 at the top of the two support rails 22, facilitating the easy pulling out of the machine body 1 and enabling full opening to the sides. The movement of the machine body 1 also moves the bottom mounting plate, and the protruding part at the bottom of the mounting plate 23 is located in the guide groove 5 on one side of the support rail 22, providing guidance for the movement of the machine body 1. The distribution of the two fixing plates 63 is used to fix the machine body 1 in two positions: one for placement and the other for maintenance, realizing dual-position switching. The limiting screw 62 inside the frame 61 is used to achieve this. The cable is threaded into the inner hole of the fixing plate 63 to fix the machine body 1. The cable extending from the machine body 1 is placed above the cable removal roller to raise the cable. The cable movement adjustment range is reserved to avoid damage to the cable caused by the movement of the machine body 1. Through the design of reserving the cable raising, the cable will not be damaged as the machine body 1 moves. The floating plate 41 is moved by the rotation of the threaded rod 44. The floating plate 41 drives the height adjustment of the cable support roller 42 to raise and lower the cable. The transmission component 45 is set to make the height adjustment of the cable support roller 42 work in conjunction with the movement of the machine body 1.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
