Description

Technical Field

[0001] The present invention relates to the technical field of dust-proof sheds, and in particular to a mobile dust-proof shed for assembled outdoor 220 kV GIS equipment. Background Art

[0002] GIS electrical equipment is also known as gas-insulated metal-enclosed switchgear. The advantages of GIS are that it has a compact structure, small floor area, high reliability, flexible configuration, convenient installation, strong safety, strong environmental adaptability, and very little maintenance work. During the installation process of outdoor 220 kV GIS equipment, in accordance with construction specifications, State Grid, and relevant requirements of the manufacturer, an outdoor dust-proof room needs to be set up during installation.

[0003] Existing outdoor 220 kV GIS equipment generally uses fixed or integral dust-proof sheds. The dust-proof shed is mostly composed of a support frame and a dust-proof cloth installed on the outside of the support frame. Some ventilation equipment or monitoring equipment for temperature, humidity, cleanliness, etc. are also simply installed later inside the dust-proof shed; for the fixed or integral dust-proof shed surface, when hoisting the equipment during construction, the entire dust-proof shed needs to be lifted, which is not convenient to quickly move the dust-proof shed directly to the side for equipment hoisting, time-consuming and laborious. Although there is also a method in the prior art of laying placement rails in advance at the bottom for movement, the integral or fixed dust-proof shed is also not convenient for on-site rapid assembly construction and subsequent transportation; generally speaking, it has the following disadvantages;

[0004] 1. It has the disadvantage of being inconvenient for rapid on-site assembly, and the on-site construction period is long;

[0005] 2. It has the disadvantages of being inconvenient for automatically telescoping and adjusting the dust-proof shielding length and synchronously rolling up and releasing the top dust-proof cloth, and cannot be adjusted according to the installation length of different on-site equipment, resulting in a relatively limited application range of the existing integral dust-proof shed. Moreover, the dust-proof cloth at the top is different from the side dust-proof cloth. The side dust-proof cloth is more convenient for personnel to install, while the top dust-proof cloth requires personnel to climb to the top for adjustment, which is extremely inconvenient;

[0006] 3. It has the disadvantage of being inconvenient for flexible movement alone on-site. Even with the method of setting rails, it can only move and avoid simply along the direction of the rails. When it needs to be transferred in other directions, a hoisting machine still needs to be used separately for hoisting and transferring, with low flexibility.

[0007] In order to solve the problems of inconvenient rapid on-site assembly, automatically telescoping and adjusting the dust-proof shielding length and synchronously rolling up and releasing the top dust-proof cloth, and flexible movement alone on-site, we have therefore proposed a mobile dust-proof shed for assembled outdoor 220 kV GIS equipment.

[0043] In this embodiment, the four universal wheels 5 are provided to facilitate the simple and flexible movement of the device on site by personnel. Before assembly, the personnel first respectively snap the tops of the two side plates 3 into the corresponding card slots 2, and the side plates 3 drive the corresponding rectangular card sleeves 301 to insert upward into the rectangular holes 28. At this time, the personnel use an external remote control to reverse-start the drive motor 13, so that it drives the fourth bevel gear 14 to rotate. The fourth bevel gear 14 drives the first screw rod 9 on the left front side to rotate through the third bevel gear 15. The first screw rod 9 on the left front side drives the front sprocket 11 to rotate. The front sprocket 11 drives the rear sprocket 11 to rotate through the chain 12. The sprocket 11 drives the corresponding two first screw rods 9 to rotate. At this time, the four first screw rods 9 rotate synchronously. Since the thread helix directions of the two first screw rods 9 that are opposite to each other left and right are opposite, the rotation of the two first screw rods 9 that are opposite to each other left and right can drive the corresponding two sliders 10 that are opposite to each other left and right to move in the direction away from each other. The four sliders 10 drive the two U-shaped top frames 1 to move in the direction away from each other. The U-shaped top frame 1 drives the universal wheel 5 to move through the corresponding side plate 3. As the U-shaped top frame 1 moves, the U-shaped top frame 1 gradually drives the corresponding support base 31 to slide on the rectangular guide rod 32 in the direction away from the rectangular box 8, and relaxes the compression force on the compression spring 34. At this time, the outwardly moving side plate 3 drives the corresponding rectangular card sleeve 301 to gradually sleeved on the clamping rod 30. At this time, the clamping rod 30 restricts the side plate 3 through the corresponding rectangular card sleeve 301, realizing the clamping and fixing of the side plate 3, and completing the assembly and locking of the two side plates 3 and the two U-shaped top frames 1, so that it is convenient to quickly and automatically assemble and lock the two side plates 3 and the two U-shaped top frames 1;

[0044] When it is necessary to further adjust the shielding length, continue to reversely start the driving motor 13. Similarly, the movement direction is exactly the same as that of reversely starting the driving motor 13 above. At this time, the two U-shaped top frames 1 continue to move away from each other, and drive the two side plates 3 to move away from each other. At this time, the overall length changes, achieving the effect of adjusting the shielding length according to actual needs. At the same time, when the two U-shaped top frames 1 move away from each other, they will respectively pull the two dust-proof top cloths 19 away from each other. When the above-mentioned third bevel gear 15 rotates, it will also drive the fifth bevel gear 23 to rotate. The fifth bevel gear 23 drives the second bevel gear 24 to rotate through the rotating shaft 22. The second bevel gear 24 drives the left circular shaft 18 through the first bevel gear 25. The left circular shaft 18 drives the two winding shafts 17 on the left to rotate. The winding shaft 17 on the left front side drives the first gear 27 on the left to rotate. The first gear 27 on the left drives the first gear 27 on the right to rotate relatively. The first gear 27 on the right drives the two winding shafts 17 on the right to rotate relatively with the winding shafts 17 on the left. At this time, the winding shafts 17 release the corresponding dust-proof top cloths 19 by rotating. Under the action of releasing the dust-proof top cloth 19 and the pulling of the U-shaped top frame 1, the effect of automatically releasing and laying the dust-proof top cloth 19 while adjusting the shielding and dust-proof length is achieved. After the shielding and dust-proof length is adjusted appropriately, stop the driving motor 13;

[0045] The personnel pre-lay two T-shaped guide rails 100 on the on-site ground according to the occlusion length. When the device needs to be installed on the two T-shaped guide rails 100, the device is moved to the front side of the two T-shaped guide rails 100, and the T-shaped chute 40 is aligned with the corresponding T-shaped guide rail 100. When there is an up-and-down error, the personnel can rotate the T-shaped screw rod 38 to rotate it in the corresponding first threaded hole and move up or down. The T-shaped screw rod 38 drives the corresponding rectangular seat 37 to slide up or down in the box-shaped seat 36, and the rectangular seat 37 drives the corresponding two universal wheels 5 to move up or down. By adjusting the relative distance between the universal wheel 5 and the corresponding box-shaped seat 36, the up-and-down height of the device can be finely adjusted, and then the up-and-down height of the T-shaped chute 40 can be adjusted. After adjustment, the device is continuously pushed backward, so that the two T-shaped chutes 40 are respectively sleeved backward on the corresponding T-shaped guide rails 100. At this time, the device can be stably moved back and forth on the two T-shaped guide rails 100. Through the transformable moving mode of the universal wheel 5 and the T-shaped guide rail 100, it is convenient to move stably on the site and can also be flexibly moved individually according to actual needs. After installation, the personnel can respectively bond multiple first dust-proof cloths 101 to the first male magic tapes 102 on the front and back sides through the corresponding first female magic tapes to form dust-proof occlusion of the front and back sides. When hoisting equipment on the site, the first dust-proof cloths 101 on the front and back sides can be lifted or removed, and then the device is moved back and forth on the two T-shaped guide rails 100 to avoid the equipment placement position. Then, after the equipment hoisting is completed, the device is moved back to its original position. In addition, when the device is fixedly used on the site for a long time, the personnel can fix the four corners of the device to the four external steel wire ropes on the external ground through the fixed steel wire ropes on the external ground to temporarily limit and fix the device at the construction site;

[0046] After subsequent use, when disassembly is required, first slide the device forward from the two T-shaped guide rails 100, and then start the driving motor 13 in the forward direction. Similarly, the movement direction is exactly opposite to that when the driving motor 13 is started in the reverse direction. At this time, the two U-shaped top frames 1 change to retract in the direction of approaching each other, reducing the volume. The two U-shaped top frames 1 drive the two side plates 3 to move back in the direction of approaching each other. The two U-shaped top frames 1 drive the two pressing plates 33 to move in the direction of approaching each other through the two support seats 31 and a plurality of compression springs 34 in sequence. When the pressing plate 33 moves to contact the corresponding rectangular box 7, it will be blocked and restricted from moving further. The pressing plate 33 restricts the latch 30 from moving through the corresponding rectangular guide rod 32 and rectangular slider 29. At this time, continue to move the support seat 31 to compress the corresponding compression spring 34. At this time, the continuously moving side plate 3 drives the corresponding rectangular socket 301 to separate from the latch 30 in the direction of approaching the rectangular box 8, releasing the clamped and locked state. At this time, the two winding shafts 17 opposite to each other left and right change to repulsive rotation, and synchronously and automatically wind up the two dust-proof top cloths 19. At this time, the operator can lift the two U-shaped top frames 1 upward to separate them from the two side plates 3, completing the disassembly, which facilitates the functions of single-drive for rapid assembly and locking, automatic telescopic adjustment of the dust-proof shielding length, and synchronous winding and releasing of the top dust-proof top cloth 19, saving time and effort and improving the on-site assembly and disassembly efficiency.
