DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0022] A coal mine underground drainage early warning device, such as Figure 1-5 As shown, it includes an inclined bucket 1, a guardrail 2, a middle frame 3, a drainage pipe 4, a closed bin 5, a discharge mechanism 6 and an early warning mechanism 7. The middle part of the inclined bucket 1 is detachably installed with a guardrail 2, which is made of cast iron and has high compressive strength. The lower middle side of the inclined bucket 1 is connected to the middle frame 3, and the left and right sides of the interior of the middle frame 3 are inclined inward. The guardrail 2 is located on the upper part of the middle frame 3, and the lower left side of the middle frame 3 is connected to three drainage pipes 4. The lower right side of the middle frame 3 is connected to the closed bin 5. A discharge mechanism 6 for automatic dredging and discharge is provided between the drainage pipe 4 and the closed bin 5. An early warning mechanism 7 for detecting and warning of blockage is provided on the middle frame 3.

[0023] The unloading mechanism 6 includes a motor 61, a thick shaft 62, a transmission belt 63, a thin shaft 64 and a paddle 65. The motor 61 is connected to the right side of the middle of the closed bin 5, and the thick shaft 62 is connected to the output shaft of the motor 61. The drain pipe 4 is equipped with a rotating thin shaft 64. The thin shaft 64 in the middle drain pipe 4 is connected to the thick shaft 62. A transmission belt 63 is connected between the thick shaft 62 and the thin shafts 64 in the front and rear drain pipes 4 through a pulley. The pulley on the thick shaft 62 is larger than the pulley on the thin shaft 64. The angle between the pulley on the thick shaft 62 and the transmission belt 63 is less than 120 degrees. The outer side of the left part of the thin shaft 64 is connected to the paddle 65, and the paddle 65 is located inside the corresponding drain pipe 4 respectively.

[0024] The early warning mechanism 7 includes a guide rail 71, a buoyancy airbag 72, a detection point 73 and a displacement sensor 74. The guide rail 71 is connected to the upper rear inner wall of the middle frame 3. The lower part of the guide rail 71 is slidably connected to the buoyancy airbag 72. The left and right sides of the buoyancy airbag 72 are connected to the detection point 73. The upper rear inner wall of the middle frame 3 is connected to the left and right displacement sensors 74. The displacement sensor 74 is electrically connected to the motor 61.

[0025] The accumulated water in the mine will be gathered to the middle through the inclined bucket 1 and then discharged into the middle frame 3. The impurities in the accumulated water will be blocked by the fence 2 to prevent the pipe from being blocked. After being discharged into the middle frame 3, it will be diverted and discharged through the drain pipe 4 respectively, thereby avoiding the problem of drainage caused by the blockage of one of the drain pipes 4. During the drainage process, if the drain pipe 4 is blocked, it will cause the accumulated water to accumulate, thereby causing the water level in the middle frame 3 to rise, which will cause the buoyancy airbag 72 to float up due to the rising water level, and then cause the detection point 73 to move. The displacement sensor 74 can detect the movement of the detection point 73 and send a signal. The collected data is transmitted to the ground control center in real time to issue an early warning. At the same time, the motor 61 will be started, which can drive the thick shaft 62 to rotate, and then the thin shaft 64 is rotated through the pulley and transmission belt 63, which in turn drives the paddle 65 to rotate, so that the impurities in the drain pipe 4 are squeezed out, thereby reducing the trouble of the staff to dredge. When the water level drops to a certain level, the motor 61 will be turned off.

[0026] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
