Description

Technical Field

[0001] The invention relates to a sinking type mine fire door sealing device, in particular to a sinking type mine fire door which can be effectively sealed in the presence of a belt conveyor in a mine tunnel. Background Art

[0002] In the current field of fire door design, there has always been a serious problem: fixed-mounted belt conveyors pose a huge obstacle to the airtightness of fire doors, seriously reducing the airtightness of fire doors. In traditional fire door designs, belt conveyors are usually installed in a fixed position. This installation method results in the fire door not being able to be completely sealed when closed, thereby reducing its fire protection effect in the event of a fire.

[0003] The existence of this problem makes the existing fire door design unable to provide sufficient safety and effectiveness when facing fire risks. In the event of a fire, the airtightness of the fire door is crucial. It should be able to effectively isolate the spread of fire, reduce the spread of smoke, and buy precious time for personnel evacuation. However, due to the presence of a fixed-mounted belt conveyor, the fire door cannot be completely sealed, which seriously weakens its role in fire scenarios.

[0004] In order to solve this problem, this patent proposes an innovative fire door design, which aims to overcome the influence of fixed belt conveyors on the airtightness of fire doors, improve the airtightness of fire doors, and thus enhance their protective performance in the event of fire. Through the design proposed in this patent, we can effectively improve the defects of existing fire doors in practical applications, protect the lives and property of personnel, and improve the overall fire safety level of buildings. Summary of the invention

[0005] The problem to be solved by the present invention is the problem of complete sealing of the belt conveyor in the case of a mine. To solve the above problem, the present invention is implemented through the following technical scheme: a sunken mine fire door sealing device, including a belt conveyor frame, a belt conveyor belt, a belt conveyor roller, a sealer, a sealing gate, a sealing road, a resistance reduction roller, a locking pin, a first rope, a second rope, coal, a hydraulic pipeline, a closed air door, an adjustment window, a pulley, a liquid storage container, liquid, an energy storage counterweight, and a gate valve; the adjustable sealing window is arranged above the closed air door, and the closed air door and the outer side of the adjustable sealing window are fixed around the mine to form a closed space; the cross section of the belt conveyor frame is smaller than the cross section of the sealer, And passes through the sealer; the sealer passes through the sealed air door, and the outer wall of the sealer is fully sealed and welded to the inner wall of the sealed air door; the belt conveyor rollers are provided in plurality and independently fixed to the ground; the top and bottom of the sealing gate are respectively provided with resistance reduction rollers and locking pins, and are movably placed in the middle of the sealing channel; the two ends of the first rope are respectively connected to the resistance reduction rollers and the bottom of the liquid storage container; the second rope is wound around the pulley and the two ends are respectively connected to the top of the liquid storage container and the top of the energy storage counterweight; the two ends of the hydraulic pipeline are respectively connected to the bottom of the liquid storage container and the inside of the sealer, and a gate valve is installed in the middle.

[0006] Furthermore, the height of the sealing path is higher than the coal on the belt of the belt conveyor during normal operation.

[0007] The advantage of adopting the above further scheme is that the sealing path is higher than the coal on the belt conveyor belt during normal operation, so that after the liquid is injected into the sealer through the hydraulic pipeline, the final liquid height is higher than the coal on the belt conveyor belt, achieving the effect of liquid sealing.

[0008] Furthermore, the sealing gate, sealing road, resistance reduction roller, locking pin, liquid storage container, pulley and energy storage counterweight are each provided in two groups, the sealing road is in the shape of a groove, and the sealing gate, sealing road, resistance reduction roller and locking pin are arranged on the left and right sides of the inner wall of the sealer, and the liquid storage container, pulley and energy storage counterweight are arranged on the left and right sides above the sealer.

[0009] The advantage of adopting the above further solution is that: the liquid storage container, the pulley and the energy storage counterweight are provided with two groups and are placed symmetrically on the left and right, making it easier to pull the sealing gate upward.

[0010] Furthermore, the length of the resistance reducing roller is greater than the length of the sealing gate.

[0011] The advantage of adopting the above further solution is: the resistance-reducing roller plays a role in reducing friction, thereby reducing the resistance of the sealing gate to lift.

[0012] Furthermore, the liquid storage container stores liquid, and when it is full of liquid, the resistance-reducing roller sinks below the belt of the belt conveyor.

[0013] The advantage of adopting the above further solution is that when the liquid is full, the drag-reducing roller can sink below the belt of the belt conveyor, so that the drag-reducing roller does not affect the normal operation of the belt conveyor.

[0014] Furthermore, the middle of the top of the sealer is concave downward, and the lowest position of the groove is not higher than the sealing channel.

[0015] The advantage of adopting the above further solution is that the liquid can fill both sides of the groove. Since the height of the sealing channel is higher than the lowest position of the groove, the liquid level can be higher than the lowest position of the sealer, forming a complete liquid-sealed state.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific examples.

[0020] Combination Figures 1 to 6 A sunken mine fire door sealing device, the structure of which includes a belt conveyor frame 1, a belt conveyor belt 2, a belt conveyor roller 3, a sealer 4, a sealing gate 5, a sealing road 6, a resistance reduction roller 7, a locking pin 8, a first rope 9, a second rope 10, coal 11, a hydraulic pipeline 12, a closed air door 13, an adjustment window 14, a pulley 15, a liquid storage container 16, a liquid 17, an energy storage counterweight 18, and a gate valve 19; the adjustment window 14 is arranged above the closed air door 13, and the closed air door 13 and the outer side of the adjustment window 14 are fixed to the surrounding of the mine to form a closed space, so that the outer circle of the entire fire door sealing device is sealed by welding and other methods; the cross section of the belt conveyor frame 1 is designed to be smaller than the cross section of the sealer 4, and passes through the sealer 4, and the sealing problem of the belt conveyor frame 1 in the presence of the internal structure design of the sealer 4 is achieved.

[0021] At the same time, the sealer 4 is designed to pass through the sealed air door 13, and the outer wall of the sealer 4 is fully sealed and welded to the inner wall of the sealed air door 13; there are a number of belt conveyor rollers 3, and they are all independently fixed to the ground, and no other supporting connecting rods are designed between the belt conveyor rollers 3, so that the belt can be lifted by the resistance reduction rollers 7; the top and bottom of the sealing gate 5 are respectively provided with resistance reduction rollers 7 and locking pins 8, and are movably placed in the middle of the sealing path 6. When the resistance reduction rollers 7 are pulled upward, the sealing gate 5 can slide upward along the sealing path 6 until it reaches the top of the inner part of the sealer 4.

[0022] The two ends of the first rope 9 are respectively connected to the resistance reduction roller 7 and the bottom of the liquid storage container 16; the second rope 10 is wound around the pulley 15 and the two ends are respectively connected to the top of the liquid storage container 16 and the top of the energy storage counterweight 18; the two ends of the hydraulic pipeline 12 are respectively connected to the bottom of the liquid storage container (16) and the inside of the seal 4, with a gate valve 19 installed in the middle. Initially, the weight of the liquid storage container 16 when fully loaded is set to be slightly greater than the energy storage counterweight 18, so that the sealing gate 5 can sink to the bottom of the belt under the action of gravity. After the gate valve 19 is opened, the liquid 17 in the liquid storage container 16 is gradually discharged, and finally when the weight of the energy storage counterweight 18 is greater than the sum of the weights of the liquid storage container 16 and the sealing gate 5, the energy storage counterweight 18 will pull the sealing gate 5 upward through the action of the first rope 9, the second rope 10 and the pulley 15. At this time, due to its own softness, the belt will also be lifted and pulled upward by the resistance reduction roller 7 until it reaches the top of the seal 4, achieving a sealing effect without cutting the belt.

[0023] Since the function of the sealing path 6 is to limit the movement trajectory of the sealing gate 5, the height of the sealing path 6 is designed to be higher than the coal 11 on the belt conveyor 2 during normal operation, thereby ensuring that the sealing gate 5 can be lifted upward to the top of the interior of the sealer 4 relatively smoothly.

[0024] The sealing gate 5, sealing channel 6, resistance reducing roller 7, locking pin 8, liquid storage container 16, pulley 15 and energy storage counterweight 18 are designed as two groups, and the sealing gate 5, sealing channel 6, resistance reducing roller 7 and locking pin 8 are arranged on the left and right sides of the inner wall of the closed container 4, and the liquid storage container 16, pulley 15 and energy storage counterweight 18 are arranged on the left and right sides above the closed container 4, so that the lifting of the two groups of sealing gates 5 has independent power systems respectively, and lifting is easier.

[0025] The sealing path 6 is designed to be in a groove shape and is located on both sides of the sealer 4 to provide a moving track for the sealing gate 5 when it moves upward. At the same time, the resistance reducing roller 7 is used to reduce the friction resistance during the sliding process. The resistance reducing roller 7 slides frictionally in the sealing path 6. Therefore, the length of the resistance reducing roller 7 is designed to be greater than the length of the sealing gate 5, and the sealing gate 5 does not need to be in direct contact with the sealing path 6.

[0026] The liquid storage container 16 is designed to store liquid 17. When the liquid storage container 16 is filled with liquid 17, the resistance reducing roller 7 sinks below the belt 2 of the belt conveyor, thereby not affecting the normal coal transportation of the belt conveyor 2.

[0027] In order to achieve a complete sealing effect of liquid 17, it is necessary to ensure that after the liquid 17 is injected into the sealer 4, the liquid level is higher than the lowest position inside the sealer 4, that is, in the longitudinal direction, at least one position is completely blocked by the liquid 17. In this way, a complete sealing effect of liquid 17 can be achieved. Therefore, the middle of the top of the sealer 4 is set to be concave downward, and the lowest position of the groove is not higher than the sealing channel.

[0028] When the sealing device operates normally, the liquid storage container 16 is filled with liquid 17, and the sealing gate 5 sinks below the belt conveyor belt 2. The belt conveyor belt 2 can normally transport the coal 11 through the sealer 4, thereby passing through the entire sunken mine fire door sealing device.

[0029] When the sealing device needs to enter a sealed state, the gate valve 19 is opened. At this time, the liquid 17 in the liquid storage container 16 will be gradually discharged into the seal 4. As the liquid 17 in the liquid storage container 16 decreases, the energy storage weight 18 will drop, and the liquid storage container 16 will be driven up through the second rope 10, and then the sealing gate 5 will be driven up along the groove of the sealing channel 6 through the first rope 9 until it reaches the top of the seal 4. Finally, as the height of the liquid 17 is higher than the groove set in the middle of the top of the seal 4, the sealing device achieves a complete sealing effect.

[0030] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
