[0027] Embodiment 1

[0028] As Figures 1-6 shown

[0029] A rapid water-blocking wall for emergency rescue during sudden flood in underground mines includes a lower baffle 1 and an upper baffle 2. The upper baffle 2 and the lower baffle 1 are connected by insertion, and the upper baffle 2 can move up and down along the lower baffle 1.

[0030] Specifically, a receiving groove is provided inside the lower baffle 1. The upper baffle 2 is inserted into the receiving groove inside the lower baffle 1, and both ends of the upper baffle 2 are inserted into the lower baffle 1 and can slide up and down.

[0031] A concave sealing rubber plate 3 is fixed on one side of the lower baffle 1, and a convex sealing rubber plate 10 is fixed on the other side of the lower baffle 1. During use, adjacent lower baffles 1 can be spliced through the concave sealing rubber plate 3 and the convex sealing rubber plate 10 to form a seal.

[0032] An inserting bottom plate 13 is fixed at the bottom of the lower baffle 1, and the bottom of the inserting bottom plate 13 is sharp. During use, the inserting bottom plate 13 can be inserted into the roadway floor to prevent a large amount of water from gushing out from the bottom.

[0033] A receiving groove 14 is provided at the top end of the upper baffle 2. A tension spring 9 and a magnetic sealing strip 4 are provided in the receiving groove 14. The magnetic sealing strip 4 is a polyurethane strip with magnet blocks embedded inside, and magnet blocks 6 are embedded inside the magnetic sealing strip 4. One end of the tension spring 9 is fixed in the receiving groove 14.

[0034] The other end of the magnetic sealing strip 4 is arranged along the side wall of the upper baffle 2. Magnets 5 are fixedly installed on one side edge of both ends of the upper baffle 2. Therefore, the magnetic sealing strip 4 can be adsorbed on the side wall of the upper baffle 2. The lower end of the magnetic sealing strip 4 is fixed on the lower baffle 1, and the upper end of the magnetic sealing strip 4 is connected to the tension spring 9.

[0035] When the upper baffle 2 extends out from the inside of the lower baffle 1, the magnetic embedded sealing strip 4 drives the tension spring 9 and slides out from the sealing strip storage groove 14. The magnetic embedded sealing strip 4 is adsorbed on the magnet 5 under the action of magnetic force. During use, the two magnetic embedded sealing strips 4 on the side walls of two adjacent upper baffles 2 are attracted to each other under the action of magnetic force, forming a seal between the upper baffle 2 and the upper baffle 2.

[0036] On the top of the upper baffle 2, there are also several roof-contact springs 7. The lower ends of the roof-contact springs 7 are fixed to the top of the accommodation groove 14, and a separate thin steel plate is fixed to the upper end of each roof-contact spring 7. There is a gap between each thin steel plate and the thin steel plate.

[0037] On the inner side of the top of the upper baffle 2, there is a waterproof flexible cloth 15, and the waterproof flexible cloth 15 is arranged on the inner side of the roof-contact spring 7. The upper end of the waterproof flexible cloth 15 is fixed to the thin steel plate at the top of the roof-contact spring 7, and the lower end of the waterproof flexible cloth 15 is fixed to the storage groove 14. After the upper baffle 2 rises in place, the thin steel plate at the top of the roof-contact spring 7 can be in flexible contact with the uneven roadway roof, forming a basic seal to prevent a large amount of water from gushing out from the upper end.

[0038] When a sudden flood accident occurs in the mine shaft, workers quickly set up the emergency water retaining wall device of the present utility model, and multiple groups of water retaining walls are combined with each other to quickly form a complete plugging retaining wall that contacts the roof, the bottom, and the sides in the roadway, realizing the basic plugging and blocking of a large amount of mine water flowing into the roadway, preventing the further expansion and spread of the water inrush accident, and winning precious time for mine emergency rescue and disaster relief.

[0039] In this embodiment, the lifting of the upper baffle 2 relative to the lower baffle 1 is controlled by a pneumatic cylinder 11. Specifically, the bottom of the pneumatic cylinder 11 is fixed to the reinforcing plate 12 fixed on the lower baffle 1, and the top of the telescopic rod of the pneumatic cylinder 11 is fixedly connected to the top of the upper baffle 2. The pneumatic cylinder 11 can drive the upper baffle 2 to rise or fall relative to the lower baffle 1. During use, the pneumatic cylinder 11 drives the upper baffle 2 to extend out along the U-shaped groove inside the lower baffle 1, so that the roof-contact spring 7 at the top of the upper baffle 2 abuts against the roadway roof, thereby basically plugging and blocking a large amount of mine water flowing into the roadway through the retaining wall structure composed of the upper baffle 2 and the lower baffle 1.

[0040] A sealing plate 16 is fixed to the upper end of the back surface of the lower baffle 1. The sealing plate 16 has an L-shaped structure. The bottom of the sealing plate 16 is fixed to the lower baffle 1, and a protruding part is provided on the upper part of the sealing plate 16. The protruding part is in contact connection with the upper baffle 2, and the gap between the lower baffle 1 and the upper baffle 2 can be sealed through the sealing plate 16.

[0041] In the middle of the storage groove 14 on the upper part of the upper baffle 2, there are two fixing pins for fixing the tension spring 9. At both ends of the storage groove 14, a guide wheel 8 is installed respectively, through which the magnetic seal strip 4 can be conveniently bypassed. After the upper baffle 2 retracts, the magnetic seal strips 4 on both sides of the upper baffle 2 are pulled back into the storage groove 14 under the action of the tension of the tension spring 9, breaking away from the attraction of the magnet 5.

[0042] In this embodiment, the driving force of the hydraulic mechanism is high-pressure air. According to the provisions of the "Coal Mine Safety Regulations", the screw air compressor must be installed on the ground, and the high-pressure air is transported to all places such as the roadways, heading faces, coal mining faces, and electrical chambers in the whole coal mine through pipelines. When a sudden flood accident occurs underground, due to the outburst of harmful gases such as gas or the leakage and grounding of equipment, local or all tripping and power outages will occur underground. Coupled with the emergency evacuation of the operating personnel, the hydraulic pump cannot be used, and there is no time to install other power equipment. Therefore, only pneumatic or manual tools can be used, so pneumatic cylinders and pneumatic single props are adopted.

[0043] When this device is in use, the device is also provided with a pneumatic single prop 17, and the pneumatic single prop 17 is connected to the back of the lower baffle 1 through a connecting slip ring 18.

[0044] In this embodiment, on the water side of the emergency quick water stop wall in the roadway, due to the large lateral pressure of the water inrush, in order to ensure that the entire emergency quick water stop wall device will not be damaged due to the large lateral pressure of the water inrush, the lower baffle 1, the upper baffle 2, etc. must be made of high-strength materials such as steel, aluminum alloy, and carbon fiber. Its height can be determined according to the roadway height, and its width can be determined after dividing the roadway width equally.

[0045] When the device of the present utility model is in use, multiple quick water stop walls are arranged adjacent to each other, and the mutual sealing of the device is realized by a sealing plate and a sealing strip, forming a good sealing structure to prevent a large amount of water inrush blocked from bursting out, and can win precious time for disaster relief and rescue.

[0046] In this embodiment, the structures such as the sealing plate and the sealing strip adopted can be made of high-flexibility, high tensile strength, and soft sealing materials, such as flame-retardant rubber, polyurethane, etc.

[0047] The application scenario in this embodiment: According to the design of the mine water disaster prevention, at the location where the emergency quick water stop wall is set, 2 to 3 emergency quick water stop walls are set. There is a chamber for storing the emergency quick water stop wall device at the location where the emergency quick water stop wall is set, and it is usually placed in the chamber for standby; when the emergency quick water stop wall device is needed at a location other than the design, the emergency quick water stop wall device can be quickly transported from the nearby storage chamber to the location where it is needed.

[0048] The present utility model can also be used for concrete pouring forms and filling forms in coal mines underground.

[0049] The utility model discloses a quick water retaining wall for emergency rescue in case of sudden flood in underground mines. When in use, the installation work cycle includes the following steps:

[0050] The first step is to move the emergency rapid retaining wall to the set position (by flatbed mining truck, forklift, etc.), with the first piece close to the tunnel wall and perpendicular to the tunnel roof and floor;

[0051] The second step is to inject high-pressure air into the two pneumatic single columns 17 respectively, so that the pneumatic single columns 17 extend upward until they support the top plate of the tunnel, and continue to inject high-pressure air so that the single pneumatic single column 17 supports the top and bottom plates of the tunnel;

[0052] The third step is to inject high-pressure air into the pneumatic cylinder 11, and the piston of the pneumatic cylinder 11 extends upward to drive the upper baffle 2 to extend from the lower baffle 1 until the thin steel plate on the top of the top spring 7 is in close contact with the tunnel roof, thereby playing the role of sealing the tunnel roof.

[0053] Because the lower baffle 1 is slidably connected to the pneumatic single column 17, the pneumatic cylinder 11 drives the lower baffle 1 to move downward due to the reaction force of the piston extending upward. Under the action of downward pressure, the inserting bottom plate 13 of the lower baffle 1 is inserted into the bottom plate of the tunnel to play a blocking role.

[0054] At the same time, the embedded magnetic sealing strip 4 slides out from the receiving groove 14 , and the embedded magnetic sealing strip 4 is attracted to each other by the embedded magnet block 6 and the magnet 5 , thereby achieving a sealing effect.

[0055] Through the above three steps, the installation of an emergency rapid water retaining wall is completed. By analogy, N emergency rapid water retaining walls are installed side by side to block the entire width of the tunnel. Adjacent emergency rapid water retaining wall devices are sealed with sealing plates and sealing strips to complete the blocking work of a water retaining wall.

[0056] By analogy, the second or third retaining wall blocking work is completed one by one according to the above method and steps.

[0057] The utility model is simple and easy to operate, has a simple system, and plays a role in rapid emergency blocking. The water retaining wall is quickly erected in a short time, which can solve the problem of large-scale water bursting, prevent the further expansion of the water inrush accident, and buy precious time for the evacuation of personnel and emergency rescue in the mine. At the same time, a large number of operators are not required at the blocking operation site. In the event of danger, the further expansion of secondary disasters can be avoided, and the casualties of operators and huge economic losses of the mine can be avoided.

[0058] The utility model solves the problem of quickly erecting a water retaining wall device in case of sudden flood accidents in underground mines, realizing the rapid blocking of a large amount of water gushing into the mine. Due to the water retaining effect of the emergency rapid water retaining wall device, the problem of a large amount of water gushing out of the mine in a short time can be quickly solved, winning precious time for the evacuation of personnel underground in the mine. At the same time, at the plugging operation site, a large number of operators are not required. In case of danger, the further expansion of secondary disasters can be avoided, and the casualties of operators can be avoided;

[0059] The utility model realizes simple and easy operation, with a simple system, playing an emergency and rapid plugging and blocking role. After quickly erecting the water retaining wall device and realizing the rapid plugging and blocking of a large amount of water gushing into the mine, the further expansion and spread of water inrush disasters can be prevented. At the same time, a large number of mechanical equipment and plugging materials are not required at the operation site; after the utility model prevents the further expansion and spread of water inrush disaster accidents, precious time is gained for the mine managers and professional and technical personnel in formulating the emergency rescue plan measures and making decisions on the implementation of the plan, which is conducive to the timely promotion and deployment of the implementation of the emergency rescue plan measures for the whole underground mine, can avoid the flooding of the whole underground mine's electrical chambers, mechanical equipment, etc., and can avoid huge economic losses of the mine.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
