[0034] Figure 5 is Figure 4 a reference diagram of a use state of the quick separation device shown. Detailed Embodiments

[0035] Figure 1 is a schematic structural diagram of a quick separation device according to an embodiment of the present invention; as Figure 1 shown and referring to Figures 2 to 5 , an embodiment of the present invention provides a quick separation device for a collective defense space. The collective defense system generally includes a collective defense space, an air purification system for delivering clean air into the collective defense space, and a pressure relief valve for discharging the gas in the collective defense space. The air purification system inputs clean air into the collective defense space, and the pressure relief valve discharges clean air into the external space, so as to keep a positive pressure environment in the collective defense space and prevent harmful gases from the outside from automatically penetrating into the collective defense space. The harmful gas can be a toxic gas, etc. The quick separation device is arranged in the collective defense space to partition at least one temporary space in the collective defense space, so that the collective defense space has a temporary space and a conventional space outside the temporary space. A seal is provided between the temporary space and the conventional space.

[0036] Specifically, the quick partitioning device includes three-sided walls 51, a partition cloth 52, and a turntable 53. Each wall 51 is a telescopic fence that can be telescoped in the up-and-down direction. The partition cloth 52 is installed on the three telescopic fences. The turntable 53 is rotatably installed on the top wall of the collective defense space, and the upper end of each telescopic fence is installed on the turntable 53. The turntable 53 drives the walls 51 to rotate so that the side walls of the temporary space are closed by the side walls of the collective defense space. A strip of iron is provided at the bottom end of the partition cloth 52, and a bendable soft magnetic strip extending in the vertical direction is provided between two vertically spaced edges of the partition cloth 52. Electromagnets are provided on the bottom wall and the side walls of the collective defense space so that the soft magnetic strip is adsorbed on the side walls and the strip of iron is adsorbed on the bottom wall. It can achieve a quick opening of the temporary space and ensure the sealing performance.

[0037] In the quick partitioning device for the collective defense space according to the embodiment of the present invention, it can quickly make the collective defense space a large space as needed, or make the collective defense space include multiple spaces, that is, form a temporary space, so as to facilitate the use of the collective defense space. That is to say, the quick partitioning device makes the temporary space not occupy space when not in use, can be quickly opened when in use, and has relatively high sealing performance.

[0038] In some preferred embodiments of the present invention, the quick partitioning device further includes a size adjustment device configured to adjust the size of the horizontal cross-section of the temporary space during the rotation of the turntable 53. The size of the temporary space can also be simply adjusted, and the size adjustment and the rotation and closing are carried out simultaneously, improving the construction efficiency of the temporary space.

[0039] For example, in some embodiments of the present invention, the upper end of each wall 51 is movably mounted on the turntable 53 along the radial direction of the turntable 53. The size adjustment device includes an adjustment disk 54, an adjustment ring 55, two fixed claws 57, and a motor drive device. The adjustment disk 54 is coaxially arranged with the turntable 53 and is rotatably arranged relative to the turntable 53. Three guide grooves are evenly distributed on the adjustment disk 54. The distances from the two ends of each guide groove to the center of the adjustment disk 54 are not equal, and the connecting lines between the two ends of each guide groove and the center of the adjustment disk 54 are cross - arranged. A slide rod 56 extending along the radial direction of the adjustment disk 54 is arranged on the adjustment disk 54, and the slide rod 56 is movably arranged along its length direction. The adjustment ring 55 is mounted on the top wall of the collection and prevention space, is coaxially arranged with the adjustment disk 54, and is located outside the adjustment disk 54. The two fixed claws are respectively mounted at both ends of the slide rod. When the slide rod moves inward, the inner fixed claw grips the turntable, so that the adjustment disk and the turntable rotate synchronously. When the slide rod moves outward, the outer fixed claw grips the adjustment ring, and the inner fixed claw disengages from the turntable. For example, the fixed claw 57 includes an upper fixing plate, a lower fixing plate, a bracket, and a clamping spring. The bracket is mounted on the slide rod 56. One of the upper fixing plate and the lower fixing plate is movably mounted on the bracket in the up - and - down direction, and the other is fixed to the bracket to form a clip with an opening facing the turntable 53. The clamping spring is arranged between the upper fixing plate and the lower fixing plate to urge the upper fixing plate and the lower fixing plate to clamp the turntable 53.

[0040] The motor drive device is a linear motor. The linear motor is mounted on the adjustment disk and is configured to drive the slide rod to move. During use, the linear motor drives the slide rod 56 to move outward. The outer fixed claw grips the adjustment ring, and the turntable 53 rotates to drive the wall 51 to rotate. The adjustment disk 54 does not move, and the guide grooves on the adjustment disk 54 cause the three walls 51 to expand outward, and the internal space of the temporary space becomes larger. When the internal volume of the temporary space becomes larger and meets the preset requirements, the motor drive device drives the slide rod 56 to retract, and the fixed claw 57 makes the turntable 53 and the adjustment disk 54 rotate synchronously.

[0041] The slide rod 56, the two fixed claws 57, and the motor drive device can form a fixing device. The fixing device is configured to controllably fixedly connect the adjustment disk 54 and the turntable 53, so that the adjustment disk 54 and the turntable 53 rotate synchronously, or fixedly connect the adjustment disk 54 and the adjustment ring 55, so that the adjustment disk 54 and the turntable 53 can rotate relative to each other. In some other embodiments, the fixing device can also adopt other structures.

[0042] In some embodiments of the present invention, the telescopic fence includes a first cross bar 58, a second cross bar, an upper telescopic rod, a lower telescopic rod, and a plurality of cross bar units. The first cross bar 58 is connected to the turntable, and the second cross bar is disposed below the first cross bar 58. The plurality of cross bar units are arranged in sequence in the vertical direction, and each cross bar unit includes a first inclined bar and a second inclined bar whose middles are hinged to each other. The lower end of the first inclined bar of the upper cross bar unit is hinged to the upper end of the second inclined bar of the upper cross bar unit, and the lower end of the second inclined bar of the upper cross bar unit is hinged to the upper end of the first inclined bar of the upper cross bar unit. The upper ends of the first inclined bar and the second inclined bar of the uppermost cross bar unit are both slidably mounted on the first cross bar 58, and the lower ends of the first inclined bar and the second inclined bar of the lowermost cross bar unit are both slidably mounted on the second cross bar. The upper end of the upper telescopic rod is fixed to the first cross bar 58, and the lower end is hinged to the middles of the first inclined bar and the second inclined bar of the uppermost cross bar unit. The lower end of the lower telescopic rod is fixed to the second cross bar, and the upper end is hinged to the middles of the first inclined bar and the second inclined bar of the lowermost cross bar unit.

[0043] Further, a handle is provided on the second cross bar, and a gear switch is provided on the handle. The gear switch includes a pressure switch and a size adjustment switch. When a person pulls the handle downward, when the pressure switch senses a certain pressure, the turntable is rotated by the controller driven by the motor. The size adjustment switch is a mechanical push switch for controlling the linear motor and adjusting according to needs.

[0044] In order to prevent the side wall of the anti-concentration space from interfering with the rotation of the wall, the side wall corresponding to the quick separation device can be a groove structure recessed outward from the anti-concentration space. In some preferred embodiments of the present invention, as Figure 4 and Figure 5 shown, the first cross bar 58 and the second cross bar in the two relatively arranged telescopic fences are both telescopic rods, and the corresponding plurality of cross bar units are mounted on the fixed parts of the first cross bar 58 and the second cross bar. The telescopic parts of the first cross bar 58 and the second cross bar are used to extend out towards the side wall of the anti-concentration space. A spring for shortening the first cross bar 58 is provided between the telescopic part and the fixed part of the first cross bar 58, and a spring for shortening the second cross bar is provided between the telescopic part and the fixed part of the second cross bar. The structure that the first cross bar 58 and the second cross bar in the two relatively arranged telescopic fences are both telescopic rods enables the wall not to interfere with the side wall of the anti-concentration space during rotation. After the electromagnet is turned on, the first cross bar 58 and the second cross bar are stretched to close the temporary space. Of course, in this embodiment, the side wall corresponding to the quick separation device can be a groove structure recessed outward from the anti-concentration space.

[0045] To improve the firmness, as Figure 4 and Figure 5As shown, a first telescopic rod 59 is provided between two adjacent first cross bars 58, and two ends of the first telescopic rod 59 are hinged to ends of the corresponding two first cross bars 58. A second telescopic rod is provided between two adjacent second cross bars, and two ends of the second telescopic rod are hinged to ends of the corresponding two second cross bars.
