DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4In this embodiment, a special steel structure enclosure includes a support frame 1 and multiple enclosure panels 2. The multiple enclosure panels 2 are each provided with a rotating shaft 8 rotatably connected to the support frame 1. An equipment room 4 and a transmission room 6 are provided inside the support frame 1. A transmission shaft 7 is provided in the transmission room 6. The transmission shaft 7 is connected to the rotating shaft 8 through a transmission mechanism. A power mechanism connected to the transmission shaft 7 is provided in the equipment room 4.

[0022] A bottom groove 11 is provided on the bottom wall of the support frame 1, a double-headed screw 12 is rotatably provided in the bottom groove 11, two racks 13 are threadedly sleeved on the double-headed screw 12, a rotating frame 14 is rotatably provided in the bottom groove 11, the rotating frame 14 is connected to the rack 13 through a meshing mechanism, a moving wheel 16 is installed on the rotating frame 14, and a support seat 3 is installed on the bottom wall of the support frame 1.

[0023] The transmission mechanism includes a driving gear 9 arranged on the transmission shaft 7, and a transmission gear 10 is installed at the end of the rotating shaft 8. The driving gear 9 is meshed with the transmission gear 10. Power transmission can be achieved with the help of the driving gear 9 and the transmission gear 10. When the transmission shaft 7 rotates, the synchronous rotation of multiple rotating shafts 8 can be achieved.

[0024] The power mechanism includes a drive motor 5 disposed in the equipment room 4. The output shaft of the drive motor 5 is fixedly connected to the end of the transmission shaft 7. The drive motor 5 is a power device of the transmission shaft 7 and can drive the transmission shaft 7 to rotate after being started.

[0025] The meshing mechanism includes a meshing gear 15 mounted on a rotating frame 14, which meshes with a rack 13. As shown in the figure, the rack 13 is L-shaped. When it moves on the double-headed screw 12, it can drive the rotating frame 14 to rotate in the bottom groove 11 with the help of the meshing gear 15.

[0026] A limit rod 17 is provided in the bottom groove 11 , and the limit rod 17 is parallel to the double-headed screw 12 . The limit rod 17 slides through the rack 13 . The limit rod 17 has a limiting function, which can limit the rack 13 to prevent it from rotating with the double-headed screw 12 .

[0027] The moving wheel 16 is a universal wheel, and a plurality of insertion rods are installed on the support seat 3. When the moving wheel 16 is in a folded storage state, the support frame 1 and other components are supported by the support seat 3, and the insertion rods on the bottom wall of the support seat 3 are inserted into the ground to ensure the stability of the device when it is placed.

[0028] When the utility model is used, Figure 1 As shown, the device as a whole forms a fence, which can separate the construction site from the outside world. In this state, the device as a whole is supported by the support seat 3, and the moving wheel 16 is stored in the bottom groove 11.

[0029] When the entire device needs to be moved, the power device (motor) located in the bottom groove 11 and connected to one end of the double-headed screw 12 is started. The power device drives the double-headed screw 12 to rotate. When the double-headed screw 12 rotates, the rack 13 threadedly mounted thereon will move. Therefore, it drives the rotating frame 14 to rotate in the bottom groove 11 with the help of the meshing gear 15, and changes from a horizontal state to a vertical state. Then the entire device will be lifted up and supported by the moving wheels 16. At this time, the entire device is supported by the moving wheels 16, which has the advantage of convenient movement.

[0030] During the use of the device, the multiple panels 2 are in a vertical state. In this state, the enclosure is airtight. If the drive motor 5 is started at this time, the drive motor 5 can drive the transmission shaft 7 to rotate. The transmission shaft 7 cooperates with the active gear 9 and the transmission gear 10 to drive the rotating shaft 8 to rotate, thereby driving the panels 2 to rotate. It can be changed from a vertical state to an inclined state or a horizontal state, and then it has a ventilation effect. It can be specially used in scenes where ventilation or airtightness needs to be adjusted at any time.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
