[0012] As a further limitation of this technical solution, the symmetrical warning plates are respectively fixedly connected to a set of evenly distributed warning lights.

[0013] A method for using a waterproof support structure in a coal mine, characterized by comprising the following steps:

[0014] S1: Place this device in a low-lying area of ​​the roadway and adjust the low-lying area to match the bottom plate. Fix the water pipe to connect to the mine drainage pipe so that the bottom plate contacts the adjusted flat area. Under the action of the first spring, the upper support plate is flush with the road surface.

[0015] S2: Rotate the vertical threaded cylinder so that the vertical top block contacts the top of the roadway, thereby fixing the device;

[0016] S3: When there is little water accumulation in the low-lying area of ​​the tunnel, the buoyancy plate rises after the water level rises, and the warning plate stands up when it floats up, thus achieving the warning function at this time. When it does not float up, it will not affect the progress. The squeezing rod moves downward to squeeze the horizontal plate, causing the second spring to be compressed. The plug moves away from the plug hole, and the cylinder enters the plug hole. Water flows from the drainage half-cylinder groove through the round hole and the plug hole into the water pipe and is discharged.

[0017] S4: When there is a lot of water in the low-lying area of ​​the tunnel, the buoyancy plate rises after the water level rises, the support contacts the bottom plate, the water flow drives the water wheel to rotate, and the lever swings. The lever pushes the slag and stones to the periphery to prevent the drainage trough from being blocked.

[0018] S5: When the water pipe is full of water, the buoyancy block rises under the action of water pressure, so that the plug is completely inserted into the plug hole, preventing water from overflowing from the water pipe.

[0019] As a further limitation of this technical solution, when the buoyancy plate rises, it causes the upper support plate to move upward along the column. The upper support plate causes the upper connecting rod to swing. The upper connecting rod causes the horizontal plate to move along the guide rod. The horizontal plate stretches the first spring. The horizontal plate causes the lower connecting rod to swing. The lower connecting rod causes the lower support plate to move downward along the column. The lower support plate causes the squeezing rod to move. The connecting rod, in conjunction with the first spring, achieves a buffering effect, maintaining a balanced state before and after water intake. The buoyancy plate can also buffer pressure.

[0020] As a further limitation of this technical solution, when the water wheel rotates, it drives the central shaft to rotate, the central shaft drives the L-plate to rotate, the L-plate drives the paddle, the mounting base, the circular plate and the L-rod to revolve, the L-rod drives the ball to move along the inclined groove, the ball drives the L-rod to swing, the L-rod drives the circular plate to rotate, and the circular plate drives the mounting base and the paddle to swing.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] 1. This device utilizes a first spring to keep the two support plates close to the main frame. When water accumulates, the buoyancy plate rises, causing the upper support plate to move upwards along the column. The warning plate stands upright when floating, providing a warning at that moment. When not floating, it does not hinder forward movement. The lower support plate moves downwards along the column, and the compression rod moves downwards to compress the horizontal plate. The cylinder enters the plug hole, and water flows from the lower half-column groove through the round hole and plug hole into the water pipe for discharge. As the water volume decreases, the buoyancy plate moves downwards, buffering the pressure. The connecting rod, combined with the first spring, achieves the buffering effect, maintaining a balanced state before and after water intake.

[0023] 2. When the water volume is large, the slag and stones will flow with the water, requiring slag removal. When the water volume is small, there is less slag, and no power-free slag removal is needed. When the water volume is large, the squeezing rod moves to its maximum range, causing the support to contact the base plate. The water flow drives the water wheel to rotate, causing the paddle to swing. The paddle pushes the slag and stones to the perimeter, preventing them from clogging the drain tank and thus preventing blockage.

[0024] 3. This device uses a buoyancy block. When the water pipe is full, the buoyancy block rises under water pressure, causing the plug to fully enter the plug hole, preventing water from overflowing from the water pipe and avoiding water from entering the tunnel. Attached Figure Description

[0052] S2: Rotate the vertical threaded cylinder 22 so that the vertical top block 21 contacts the top of the roadway, thereby fixing the device.

[0053] S3: When there is little water accumulation in the low-lying area of ​​the tunnel, the buoyancy plate 45 rises after the water level rises, and the warning plate 46 stands up when it floats, thus achieving the warning function at this time. When it does not float, it will not affect the progress. The squeezing rod 48 moves downward to squeeze the horizontal plate 51, causing the second spring 57 to be compressed. The plug 55 moves away from the plug hole 310, and the cylinder 54 enters the plug hole 310. Water flows from the drainage half-cylinder groove 53 through the round hole 37 and the plug hole 310 into the water pipe 38 and is discharged.

[0054] S4: When there is a lot of water accumulation in the low-lying area of ​​the tunnel, after the water level rises, the buoyancy plate 45 rises, the bracket 52 contacts the bottom plate 32, the water flow drives the water wheel 59 to rotate, and the lever 513 swings.

[0055] S5: When the water pipe 38 is full of water, the buoyancy block 56 rises under the action of water pressure, so that the plug 55 completely enters the plug hole 310, preventing water from overflowing from the water pipe 38.

[0056] When the buoyancy plate 45 rises, it causes the upper support plate 44 to move upward along the column 36. The upper support plate 44 causes the upper connecting rod 43 to swing. The upper connecting rod 43 causes the horizontal plate 42 to move along the guide rod 33. The horizontal plate 42 stretches the first spring 41. The horizontal plate 42 causes the lower connecting rod 43 to swing. The lower connecting rod 43 causes the lower support plate 44 to move downward along the column 36.

Fix the water pipe 38 to connect to the mine drainage pipe so that the bottom plate 32 contacts the adjusted flat area. Under the action of the first spring 41, the upper support plate 44 is flush with the road surface.

[0061] S2: Rotate the vertical threaded cylinder 22 so that the vertical top block 21 contacts the top of the roadway, and rotate the horizontal threaded cylinder 12 so that the horizontal top block 11 contacts the side wall of the roadway to fix the device.

[0062] S3: When there is little water accumulation in the low-lying area of ​​the tunnel, the buoyancy plate 45 rises after the water level rises, and the warning plate 46 stands up when it floats, thus achieving the warning function at this time. When it does not float, it will not affect the progress. The squeezing rod 48 moves downward to squeeze the horizontal plate 51, causing the second spring 57 to be compressed. The plug 55 moves away from the plug hole 310, and the cylinder 54 enters the plug hole 310. Water flows from the drainage half-cylinder groove 53 through the round hole 37 and the plug hole 310 into the water pipe 38 and is discharged.

[0063] S4: When there is a lot of water accumulation in the low-lying area of ​​the tunnel, after the water level rises, the buoyancy plate 45 rises, the bracket 52 contacts the bottom plate 32, the water flow drives the water wheel 59 to rotate, and the lever 513 swings. The lever 513 pushes the slag and stones to the periphery to prevent the drainage trough 520 from being blocked.

[0064] S5: When the water pipe 38 is full of water, the buoyancy block 56 rises under the action of water pressure, so that the plug 55 completely enters the plug hole 310, preventing water from overflowing from the water pipe 38.

[0065] When the buoyancy plate 45 rises, it causes the upper support plate 44 to move upward along the column 36. The upper support plate 44 causes the upper connecting rod 43 to swing. The upper connecting rod 43 causes the horizontal plate 42 to move along the guide rod 33. The horizontal plate 42 stretches the first spring 41. The horizontal plate 42 causes the lower connecting rod 43 to swing. The lower connecting rod 43 causes the lower support plate 44 to move downward along the column 36. The lower support plate 44 causes the compression rod 48 to move. The connecting rod 43, in conjunction with the first spring 41, achieves a buffering effect, maintaining a balanced state before and after water intake. The buoyancy plate 45 can also buffer pressure.

The ball 518 drives the L-rod 517 to swing. The L-rod 517 drives the circular plate 516 to rotate. The circular plate 516 drives the mounting base 515 and the lever 513 to swing.

[0067] This device uses a first spring 41 to keep the two support plates 44 close to the main frame 31. When water accumulates, the buoyancy plate 45 rises, allowing the upper support plate 44 to move upward along the column 36. The warning plate 46 stands upright when floating, providing a warning function. When not floating, it does not affect forward movement. The lower support plate 44 moves downward along the column 36, and the compression rod 48 moves downward to compress the horizontal plate 51. The cylinder 54 enters the plug hole 310, and water flows from the lower half-column groove 53 through the round hole 37 and the plug hole 310 into the water pipe 38 for discharge. As the water volume decreases, the buoyancy plate 45 moves downward, buffering the pressure. The connecting rod 43, combined with the first spring 41, achieves a buffering effect, maintaining a balanced state before and after water intake.

[0068] When the water volume is large, the slag and stones will flow with the water, requiring slag removal. When the water volume is small, there is less slag, and no power-free slag removal is needed. When the water volume is large, the squeezing rod 48 moves to its maximum range, causing the support 52 to contact the base plate 32. The water flow drives the water wheel 59 to rotate, causing the lever 513 to swing. The lever 513 pushes the slag and stones to the periphery, preventing the slag and stones from clogging the drain trough 520, thus playing an anti-clogging role.

[0069] This device uses a buoyancy block 56. When the water pipe 38 is full of water, the buoyancy block 56 rises under water pressure, causing the plug 55 to fully enter the plug hole 310, preventing water from overflowing from the water pipe 38 and avoiding water from entering the tunnel.

[0070] The above-disclosed embodiments are merely specific examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
