DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] The underground fire isolation device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the underground fire isolation device of the embodiment of the present invention includes: a fireproof body 1, a fireproof door 2 and a driving member 3.

[0033] The fireproof body 1 is arranged along the contour of the lane, and the fireproof body 1 can be a separately manufactured frame structure, or the peripheral wall of the lane is used as the main structure. The fireproof body 1 has isolation grooves on both sides of its width direction, that is, isolation grooves are respectively opened on the peripheral walls on both sides of the lane.

[0034] The fire door 2 includes two folding doors, which are respectively arranged in two isolation grooves, and any folding door is provided with a man-passing door body 23. The fire door 2 has an open mode and a closed mode. In the open mode, the two folding doors are folded and located in the isolation grooves corresponding thereto, and in the closed mode, the two folding doors are unfolded and butted together to block the lane.

[0035] It is understandable that if Figure 1 As shown, when a fire occurs, the fire door 2 is in the closed mode, and the two folding doors are connected to each other, thereby closing the lane and blocking the spread of fire smoke. By providing a pass-through door 23, when the folding fire door 2 is closed, people can pass through the fire door 2 smoothly. Figure 2 As shown, when no fire occurs, the fire door 2 is in the open mode, and the folding door is hidden in the isolation groove to achieve full-area opening of the alley, without affecting the normal alley space, and facilitating the passage of pedestrians and vehicles.

[0036] In addition, the driving member 3 is connected to the fire door 2, and the driving member 3 is used to drive the fire door 2 to switch between an open mode and a closed mode to achieve intelligent management.

[0037] In some embodiments, Figure 1 As shown, the folding door includes a plurality of door panels connected in sequence, and two adjacent door panels can rotate relative to each other, and a sealing isolation strip 24 is provided on the peripheral wall of the door panel.

[0038] It can be understood that a limited hinge structure is used between the door panels to enable adjacent door panels to rotate and fold along a fixed direction.

[0039] Optionally, the sealing isolation strip 24 is a heat-insulating and flame-retardant material, which is filled between the gaps in the folding door structure, or between the main frame of the fire door 2 and the lane, so as to isolate and slow down the diffusion of harmful gases.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, for the convenience of description, the folding door with the door body 23 is defined as the first folding door 21, and the isolation groove corresponding to the first folding door 21 is defined as the first isolation groove 11. Another folding door is defined as the second folding door 22, and the isolation groove corresponding to the second folding door 22 is defined as the second isolation groove 12.

[0041] Among them, the cross-sectional shape of the first isolation groove 11 is L-shaped. When the fire door 2 is in the open mode, the first folding door 21 is arranged in the first isolation groove 11 along the direction of the first isolation groove 11, that is, the first folding door 21 is L-shaped after folding.

[0042] Optionally, the first folding door 21 is composed of two door panels, one of which is provided with a man-passing door body 23, and the size of the door panel is larger than the size of the other door panel. When the first folding door 21 is folded, due to the presence of the man-passing door body 23, the first folding door 21 turns and folds in the first isolation groove 11, thereby realizing reasonable storage of the first folding door 21. In addition, the turning point of the first isolation groove 11 has a cut corner 111, so as to facilitate the folding of the first folding door 21.

[0043] The cross-section of the second isolation groove 12 is square, and when the fire door 2 is in the open mode, the second folding door 22 is stacked in the second isolation groove 12 along its thickness direction. Since there is no passage for people on the second folding door 22, it is only necessary to consider how to fold the second folding door 22 to save space.

[0044] In some embodiments, Figure 1 As shown, the driving member 3 includes an explosion-proof motor, a steel wire rope 31 and two rotating wheels 32. The two rotating wheels 32 are respectively arranged on the fireproof body 1 above the two isolation grooves. The steel wire rope 31 surrounds the two rotating wheels 32, and part of the steel wire rope 31 is movably fitted in the guide groove of the rotating wheel 32. A first connecting body 311 connected to the first folding door 21 is provided on the upper half of the steel wire rope 31, and a second connecting body 312 connected to the second folding door 22 is provided on the lower half of the steel wire rope 31. The explosion-proof motor is connected to any rotating wheel 32 to drive the folding door to fold.

[0045] It can be understood that when the explosion-proof motor drives the rotating wheel 32 to rotate, the upper and lower halves of the steel wire rope 31 move in opposite directions, thereby being able to simultaneously drive the first folding door 21 and the second folding door 22 to move closer to or away from each other.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, the upper part of the fireproof body 1 is provided with a guide rail 13, and the first connecting body 311 and the second connecting body 312 can be slidably matched on the guide rail 13. In addition, the lower part of the fireproof body 1 is provided with a slide groove 14, and the lower end of the folding door is provided with a pulley matched in the slide groove 14.

[0047] Thus, the design of the guide rail 13 and the slide groove 14 ensures the stability of the folding door during the opening and closing process, helps prevent the folding door from derailing during the opening and closing process, and thus enhances the safety during use. The pulley slides in the slide groove 14, which can reduce friction, making the opening and closing of the folding door easier, and can ensure that the folding door can be quickly and effectively closed in an emergency, thereby improving the fire prevention efficiency.

[0048] The fire isolation system according to an embodiment of the present invention is described below.

[0049] The fire isolation system of the embodiment of the present invention comprises: a fire arrester, a sensor group and a control module. The fire arrester is an underground fire isolation device of any one of the above embodiments. The sensor group is used to collect underground wind flow composition and state information, and mainly includes a smoke sensor and a temperature sensor. The control module is connected to the fire arrester and the sensor group, and the control module is used to adjust the state of the fire arrester according to the information collected by the sensor group.

[0050] It can be understood that the downhole sensor group collects and monitors the downhole wind flow composition and status information, and transmits the collected information to the uphole analysis host computer (control module) through the downhole ring network substation. The host computer summarizes and analyzes the information transmitted from each substation and makes corresponding decisions. If a fire is found underground, the fire isolation device is controlled to be opened and deployed through the corresponding downhole substation.

[0051] Therefore, the fire isolation system of the embodiment of the present invention links the fire prevention and fire warning measures, and monitors the composition and status of the tunnel air volume in real time. If an abnormality is found, the system can give timely feedback to control the fire door 2 of the fire spread tunnel to close in time, suppress the diffusion of smoke, buy time for personnel evacuation, and improve underground fire safety.

[0052] In summary, underground fire isolation devices are one of the ways to realize the intelligent construction of tunnel safety systems, which makes the underground equipment transfer management more accurate, controllable and real-time. Its control form can also adapt to various tunnel forms and can be promoted in various mine tunnels. At the same time, as an intelligent system management model, it also has great promotion and application value.
