Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a mine fire isolation device, comprising: a fixed frame composed of two supporting vertical frames 8, a supporting top frame 7 and a supporting bottom frame 21 and an isolation airbag 4. The supporting top frame 7 is provided with a transmission assembly 12. The transmission assembly 12 is connected to two fixed side columns 6 through two transmission connecting plates 15. A connecting slider 23 is provided between the bottom of the fixed side column 6 and the supporting bottom frame 21. A guide slider 22 is provided between the connecting slider 23 and the inner wall of the supporting bottom frame 21. A plurality of folding door panels 5 are provided between the fixed side columns 6 and the supporting vertical frames 8. Rotating blocks 3 are provided between the folding door panels 5, between the folding door panels 5 and the fixed side columns 6, and between the folding door panels 5 and the supporting vertical frames 8. An electromagnetic connector is provided between the two facing sides of the two fixed side columns 6.
[0023] The top support frame 7 and the bottom support frame 21 are symmetrically equipped with two sets of telescopic columns 17 on their interior sides. A synchronization plate 18 is provided between the bottoms of each set of telescopic columns 17. Several blocking columns 2 are arranged on the synchronization plate 18. Two push airbags 16 are symmetrically installed on the synchronization plate 18. A connecting air pipe 19 is provided between adjacent push airbags 16. A connecting air pipe 20 is provided between different sets of push airbags 16. An inflation assembly 10 is provided on the top support frame 7 and the bottom support frame 21. A drive assembly 9 is provided on one side of the top support frame 7.
[0024] Further improvements include a fixed frame with a square structure, a top support 7 fixed at the top between the vertical support frames 8, a bottom support 21 fixed at the bottom between the vertical support frames 8, an air-blocking airbag 4 installed on one side of the folding door panel 5, and an inflation component 1 connected to the air-blocking airbag 4 through the folding door panel 5. Specifically, the fire monitoring equipment and the control equipment for the air-blocking airbag 4, the transmission component 12, and the inflation component 10 used in this technical solution all employ technical means commonly used in the relevant technical fields, which will not be described in detail here.
[0025] Further improvements include a transmission assembly 12 comprising two transmission pulleys and a transmission belt. The two transmission pulleys are symmetrically distributed at both ends of the inner wall of the supporting top frame 7, and the transmission belt is installed between the transmission pulleys. Transmission connecting plates 15 at different positions are connected to the transmission belt at different heights, specifically, as shown below. Figure 2As shown, the transmission connecting plates 15 at different positions are fixedly connected to the top and bottom parts of the transmission belt, respectively. In use, they can drive the two fixed side columns 6 to move relative to each other, thereby realizing the folding and closing blocking state of the folding door panel 5.
[0026] Further improvements include connecting the drive end of the drive assembly 9 to the transmission assembly 12, with the cross-section of the connecting slider 23 having a "T" shape, the bottom end of the connecting slider 23 being located on the guide slide rod 22 and slidably connected to it, and the folding door panels 5 having a gap between them. The rotating block 3 is rotatably connected to the folding door panel 5 and is fixedly connected to the supporting top frame 7 and the fixed side column 6. Specifically, the rotating block 3 is used for the rotation and folding of the folding door panel 5. When there is no obstruction, the folding door panel 5 is in a folded state, and the fixed side column 6 is far away, which does not affect the use of the mine.
[0027] Further improvements include an electromagnetic connector comprising an electromagnetic chuck 13 and an adsorption plate 14, which are respectively fixed to fixed side posts 6 at different positions. The adsorption plate 14 is embedded in the fixed side post 6. Each set of telescopic posts 17 consists of two units, and springs are installed inside the telescopic posts 17. Specifically, as shown... Figure 3 As shown, the spring is used to automatically retract the telescopic column 17, ensuring that the blocking column 2 is in the internal position of the supporting top frame 7 and the supporting bottom frame 21 when the pushing airbag 16 is not inflated.
[0028] In a further improvement, the blocking column 2 is movably connected to the top support frame 7 and the bottom support frame 21, pushing one side of the airbag 16 to fit against the inner wall of the top support frame 7 and the bottom support frame 21, and the inflation assembly 10 is connected to the connecting air pipe 20.
[0029] In use: This utility model first assembles the fixed frame into a square frame structure and fixes it in the mine. The gap between the fixed frame and the mine is filled and sealed with a filling material. When not in use, the two fixed side columns 6 are far apart, and the folding door panel 5 is in a folded state. The airbag 4 is stored on the inward-folding side of the folding door panel 5, which does not affect the normal entry and exit of the mine. In the event of a fire, the drive component 9 drives the transmission component 12 to rotate, further driving the two fixed side columns 6 to move relative to each other and gradually move to a contact state. At this time, the folding door panel 5 is closed. When the door panel 5 unfolds, the fixed frame is closed as a whole. Simultaneously, the electromagnetic suction plate 13 is energized and magnetically connected to the adsorption plate 14, thus fixing the side column 6 and fixing the folding door panel 5. Then, the inflation component 10 inflates the pushing airbag 16 and pushes the synchronous plate 18 to move, further pushing the blocking column 2 out from the supporting top frame 7 and supporting bottom frame 21, blocking the movement and folding of the folding door panel 5, and achieving the overall support function. When the blocking airbag 4 is inflated by the inflation component 21, the mine is sealed and blocked, ensuring the overall blocking effect.
[0030] The present invention comprises an inflatable component 2-1, a blocking column 2, a rotating block 3, a barrier airbag 4, a folding door panel 5, a fixed side column 6, a supporting top frame 7, a supporting vertical frame 8, a driving component 9, an inflatable component 1-10, a transmission component 12, an electromagnetic suction plate 13, an adsorption plate 14, a transmission connecting plate 15, a pushing airbag 16, a telescopic column 17, a synchronization plate 18, a connecting air pipe 1-19, a connecting air pipe 2-20, a supporting base frame 21, a guide slide rod 22, and a connecting slider 23. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is the use of barrier airbags... In most areas, the lack of supporting structures makes the barrier airbag prone to deformation under pressure during mine fires. Incomplete edge blocking further hinders the effectiveness of fire containment. This invention addresses this problem by combining the aforementioned components, including the electromagnetic connector, barrier columns, and pushing airbag, to effectively support the folding door panel. The magnetic connection between the electric suction plate and the adsorption plate in the electromagnetic connector maintains the stability of the connection between the two fixed side columns. The barrier columns extend to support the folding door panel, preventing it from moving during use. This avoids deformation under stress during containment and ensures effective edge blocking, guaranteeing the overall containment effect.
