[0031] In the process of underground mining, water disaster or fire disaster often occurs due to various reasons, therefore, when water disaster or fire disaster occurs in the process of underground mining, the disaster is often limited in a limited range by setting fireproof doors between each area for partition isolation protection, to prevent the disaster from further evolving, therefore, there is an urgent need for a fireproof water-blocking door to segmentally and stepwise block the fire and water disaster in the underground mine, to effectively control the spread of fire and water, and improve the safety of the underground mine.
[0032] In order to solve the technical problem of how to segmentally and stepwise block the fire and water disaster in the underground mine by a fireproof water-blocking door, to effectively control the spread of fire and water, and improve the safety of the underground mine, the present application provides a fireproof water-blocking door, which is arranged at the junction of the main roadway and the branch roadway of the mine, and the opening and closing degree of the first door plate 2 and the drainage door and window 3 is controlled by the first driving device 4 and the second driving device 5, thereby segmentally and stepwise blocking the fire and water disaster in the underground mine, to effectively control the spread of fire and water, and improve the safety of the underground mine.
[0033] In the first aspect, please refer to Figure 2 , Figure 2A structural schematic diagram of a fireproof water-blocking door provided by the embodiment of the present application, the fireproof water-blocking door comprising a door frame 1, a first door plate 2, a drainage door window 3, a first driving device 4 and a second driving device 5, wherein the door frame 1 is arranged at the junction of a main lane and a section lane of a mine, the first door plate 2 is arranged in the door frame 1 and is hinged to any side frame of the door frame 1; the driving end of the first driving device 4 is connected with the first door plate 2, the first door plate 2 can be driven to unfold and close by the first driving device 4, the first door plate 2 is provided with a first window 6, the drainage door window 3 is arranged in the first window 6 and is hinged to the first door plate 2; the driving end of the second driving device 5 is connected with the drainage door window 3 and is used for driving the drainage door window 3 to unfold, and the unfolding direction of the drainage door window 3 is opposite to the unfolding direction of the first door plate 2.
[0034] Specifically, refer to Figure 3 During the mining operation in the underground mine, water disaster or fire disaster often occurs due to various reasons, when the fire disaster occurs in the mine, the first driving device 4 and the second driving device 5 are remotely controlled to control the first door plate 2 and the drainage door window 3 to close, so as to separate the section lane where the fire disaster occurs from the main lane or other section lanes, thereby preventing the flame and smoke from spreading to the main lane or other section lanes, and the safety of the underground mine is improved.
[0035] When the water disaster occurs in the hole, the first driving device 4 and the second driving device 5 are remotely controlled to control the first door plate 2 and the drainage door window 3 to close, so as to separate the section lane where the water disaster occurs from the main lane or other section lanes, thereby blocking the water in the section lane where the water disaster occurs. However, after the water leakage point in the section lane where the water disaster occurs is repaired, the accumulated water in the section lane needs to be discharged, and when the accumulated water is in the direction of the unfolded side of the fireproof water-blocking door, the resistance of the accumulated water will affect the opening of the door plate. In the embodiment, the fireproof water-blocking door is provided with two first door plates 2 and drainage door leaves which are opened in opposite directions. When the accumulated water occurs on either side of the fireproof water-blocking door, the first door plate 2 or the drainage door leaf which is opened in the opposite direction can be opened, so that the accumulated water in the section lane can be easily discharged.
[0036] Further, in the embodiment, the fireproof water-blocking door further comprises a second door plate 7, a sliding rail 8 is arranged on the vertical frame of the door frame 1, the sliding rail 8 is arranged along the transverse direction of the door frame 1 and is arranged towards the center part of the door frame 1, one end of the second door plate 7 is hinged to the first door plate 2, the other end of the second door plate 7 is provided with a sliding block, and the sliding block is slidingly arranged in the sliding rail 8. In the use process, the first door plate 2 drives the second door plate 7 to slide during the unfolding process of the first door plate 2 driven by the first driving device 4, thereby realizing the folding of the first door plate 2 and the second door plate 7 and reducing the floor area occupied by the first door plate 2 and the second door plate 7 when they are folded.
[0037] Further, in the embodiment, the sliding rails 8 are arranged on the upper and lower vertical frames of the door frame 1, and the second door plate 7 is fixed by the sliding rails 8 arranged on the upper and lower vertical frames of the door frame 1, so that the stability of the first door plate 2 and the second door plate 7 during use is further increased.
[0038] Further, in the embodiment, the first abutting frame 9 is further arranged on the inner wall of the door frame 1 on the side facing the center, and when the first door plate 2 is closed, the side surface of the first door plate 2 is attached to the surface of the first abutting frame 9, so that the sealing property of the first door plate 2 is further improved, and the stability of the first door plate 2 during use is further increased.
[0039] Further, in the embodiment, the second abutting frame 10 is further arranged in the window, and when the drainage door and window 3 is closed, the side surface of the drainage door and window 3 is attached to the surface of the second abutting frame 10, and the side surface of the drainage door and window 3 attached to the second abutting frame 10 is opposite to the side surface of the first door plate 2 attached to the first abutting frame 9, so that the sealing property of the drainage door and window 3 is further improved, and the stability of the drainage door and window 3 during use is further increased.
[0040] Further, in the embodiment, the sealing rubber strips are arranged on the side of the first abutting frame 9 and the second abutting frame 10 in contact with the first door plate 2 or the drainage door and window 3, so that the sealing property of the fireproof and waterproof door is increased, and the penetration of water or smoke through the fireproof and waterproof door is effectively prevented.
[0041] Further, in the embodiment, the sealing rubber strips are made of thermal expansion foaming materials, such as ethylene propylene diene rubber, and a proper amount of flame retardant is added to achieve the effect of difficult combustion. When a fire occurs, the sealing rubber strips will expand due to heat, forming a sticky carbon foam. The foam will not be lost or fall off due to ash, and the burning speed is slow. The expansion area can be expanded to 15-20 times of the original area, and can be expanded in all directions or mainly in one direction, so as to completely fill the surrounding gaps and form an effective heat insulation layer and fire and smoke prevention barrier, thereby preventing the penetration of fire and smoke through the fireproof and waterproof door.
[0042] Further, in the embodiment, the fixed lock tongue is further arranged on the vertical frame of the door frame 1 in a telescopic manner, and is used to fix the first door plate 2 in the door frame 1, so that the stability of the first door plate 2 during use is further increased.
[0043] Note that the present application is not limited to the above-described embodiments. The above-described embodiments are merely examples, and embodiments having substantially the same configuration, function, and effect as the technical idea of the present application are included in the technical scope of the present application. Furthermore, other modes constructed by applying various modifications to the embodiments, or by combining part of the configurations of the embodiments, which can be conceived by those skilled in the art, without departing from the spirit of the present application, are also included in the scope of the present application.
