Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of negative pressure isolation transfer cabins, and particularly to a negative pressure isolation transfer cabin for ships that can be automatically deployed and recovered quickly. Background Art
[0002] A negative pressure isolation transfer cabin is a special device for transporting infectious patients. Its main purpose is to isolate patients during transportation to prevent the spread of pathogens, thereby protecting medical staff and the surrounding environment from infection. The working principle of the negative pressure isolation transfer cabin is to make the air pressure inside the cabin lower than the external environment through a negative pressure exhaust purification device, so that air can only flow in from the outside and cannot flow out from the inside, ensuring that the air inside the cabin will not leak out.
[0003] During the process of transporting patients in a negative pressure isolation transfer cabin, it is necessary to ensure that there is enough accommodation space inside, which leads to a large volume of the cabin body. When the equipment is in an idle state, it wastes the floor space of the ship. To solve this problem, there are two types of cabin bodies: assembled and inflatable. The assembled transfer cabin will result in a high learning cost for personnel and a long time-consuming process, thus increasing the risk of infection. The air ducts of the inflatable transfer cabin are prone to leakage, resulting in the equipment being unable to be used normally. Based on this, the present invention designs a mechanically and electrically controlled combined folding negative pressure cabin that can be automatically deployed and recovered quickly and improves space utilization. Summary of the Invention

One end of the first-stage rope 311 is fixedly connected to the flange 303, and the other end is fixedly connected to the left end of the second-stage telescopic pipe 312.

[0035] In this embodiment, in the initial state, the left ends of the nut 307, the second-stage telescopic tube 312, the third-stage telescopic tube 316, and the fixed tube 304 are flush.
[0036] The motor 302 is controlled by an external controller. The controller is used to control the motor 302 to start rotating forward when receiving a rightward automatic rapid deployment instruction, drive the lead screw 306 to rotate forward, the nut 307 moves rightward on the lead screw 306, drives the first-stage telescopic tube 308 and the first-stage movable pulley 309 inside it to move rightward in linkage. The first-stage movable pulley 309 rotates forward simultaneously, drives the second-stage telescopic tube 312 and the second-stage movable pulley 313 inside it to move rightward by twice the distance under the action of the first-stage rope 311. The second-stage movable pulley 313 rotates forward simultaneously, drives the third-stage telescopic tube 316 to move rightward by twice the distance under the action of the second-stage rope 315, and further drives the third telescopic rod 205 to move rightward by four times the distance. When the left end of the third telescopic rod 205 moves to the rightmost end of the second telescopic rod 204, it drives the second telescopic rod 204 to move. When the left end of the second telescopic rod 204 moves to the rightmost end of the first telescopic rod 203, it drives the first telescopic rod 203 to move, thereby realizing the automatic rapid rightward deployment of the third telescopic rod 205, the second telescopic rod 204, and the first telescopic rod 203 under the action of the automatic telescopic mechanism 300.
[0037] The controller is used to control the motor 302 to start reverse when receiving the automatic fast recovery instruction to the left, so as to drive the lead screw 306 to rotate in the opposite direction, and the nut 307 moves to the left on the lead screw 306, driving the primary telescopic tube 308 and the primary movable pulley 309 therein to move in a left linkage manner, and the primary movable pulley 309 rotates in the opposite direction at the same time, and the secondary telescopic tube 312 and the secondary movable pulley 313 therein move twice to the left under the action of the primary rope 311, and the secondary movable pulley 313 rotates in the opposite direction at the same time, and under the action of the secondary rope 315 The third telescopic tube 316 is driven to move twice to the left, thereby driving the third telescopic rod 205 to move four times to the left. When the right end of the third telescopic rod 205 moves to the right end of the second telescopic rod 204, it drives the second telescopic rod 204 to move. When the right end of the second telescopic rod 204 moves to the right end of the first telescopic rod 203, it drives the first telescopic rod 203 to move, thereby realizing automatic and rapid retraction of the third telescopic rod 205, the second telescopic rod 204 and the first telescopic rod 203 to the left under the action of the automatic telescopic mechanism 300.
[0038] In this embodiment, the motor 302 starts to rotate forward, and the primary telescopic tube 308 is pushed to translate axially to the right through the screw nut mechanism. The primary telescopic tube 308 simultaneously drives the primary movable pulley 309 to translate axially to the right, thereby causing the secondary telescopic tube 312 to translate axially to the right. The displacement relationship between the two is that the secondary telescopic tube 312 is twice that of the primary telescopic tube 308. At the same time, the primary tension spring 319 is stretched by the extension of the secondary telescopic tube 312. The secondary telescopic tube 312 simultaneously drives the secondary movable pulley 313 to translate axially to the right, thereby causing the tertiary telescopic tube 316 to translate axially to the right. The displacement relationship between the two is that the tertiary telescopic tube 316 is twice that of the secondary telescopic tube 312. At the same time, the secondary tension spring 322 is stretched by the extension of the tertiary telescopic tube 316. At this point, the automatic telescopic mechanism 300 is fully opened.
