[0023] Embodiment three As shown in Figure 2 , Figure 4 and Figure 8 , the application provides a water disaster and rock burst coupling monitoring and early warning device, a knocking assembly 8 is fixedly installed at the bottom end of a shell 1, the knocking assembly 8 comprises a bottom pipe 81, the bottom pipe 81 is fixedly installed at the rear end of the inner cavity of the shell 1, a knocking rod 82 is slidably connected in the inner cavity of the bottom pipe 81, a spring 83 is sleeved on the outer side of the knocking rod 82, a guide block 84 is fixedly installed at the front end of the spring 83, a pressing rod 85 is fixedly installed at the bottom end of the lifting plate 42, the pressing rod 85 is in contact with the guide block 84, the front end of the guide block 84 is a slope, and the front and rear ends of the spring 83 are fixedly connected with the knocking rod 82 and the shell 1 respectively.

[0024] The working principle and beneficial effects of the above technical scheme are as follows: When the push rod 41 drives the lifting plate 42 to move upward, the lifting plate 42 drives the pressing rod 85 to move upward, when the pressing rod 85 is separated from the guide block 84, the spring 83 in the compressed state drives the knocking rod 82 and the guide block 84 to move forward under the elastic action; When the lifting plate 42 is lowered, the lifting plate 42 drives the pressing rod 85 to move downwards, the pressing rod 85 is in contact with the guide block 84, the guide block 84 is pushed backwards, the spring two 83 is compressed, and the spring two 83 knocks on the roadway, thereby simulating vibration, when all the microseismic sensors 91 completely detect the vibration, it indicates that the device is in normal use, and when some microseismic sensors 91 do not detect the vibration, it indicates that the device is damaged and needs to be replaced.

[0025] The working principle and use process of the present application are as follows: During installation, first, the shell 1 is installed in the roadway, and the shell 1 is fixed, which can be installed in a bolt connection mode or a direct installation mode; After installation, first, the power line 93 and the water level sensor 92 are screwed on the power interface 94 and the water level connection port 95 respectively, and the other end of the water level connection port 95 is inserted into the position where the water level needs to be detected; Then, the push rod 41 is pushed upwards, the push rod 41 drives the rack one 71 and the lifting plate 42 to move upwards, the upward movement of the rack one 71 drives the gear shaft 72 to rotate, thereby driving the driven gear 73 to rotate, the driven gear 73 drives the blocking strip 63 to move backwards through the meshing with the rack two 74, thereby driving the blocking strip 63 to move away from the left end of the iron sheet 61; The upward movement of the lifting plate 42 compresses the spring one 43, and the air in the fixed box 31 is squeezed into the side pipe 35 through the three-way pipe 32, when the air enters the side pipe 35, the moving shaft 55 is pushed to move, the moving shaft 55 drives the microseismic connection port 53 to move away from the center of the shell 1 through the connecting frame 54 and the moving iron plate 52, and inserts into the sealing ring, and pushes the iron sheet 61 to rotate, opens the sealing ring, and as the push rod 41 continuously moves upwards, the microseismic connection port 53 continuously extends out; When the moving shaft 55 moves to the side of the air outlet pipe 36 away from the fixed box 31, the gas in the side pipe 35 enters the shell 1 through the air outlet pipe 36, when the moving iron plate 52 contacts with the side wall of the shell 1, the microseismic connection port 53 does not extend out, at this time, the indicating line on the push rod 41 has not completely entered the shell 1, continue to move the push rod 41 upwards, if the shell 1 does not appear deformation and damage caused by sealing failure, the gas squeezed out of the air outlet pipe 36 enters the shell 1, increases the pressure in the shell 1, and continues to move the push rod 41 upwards, which will produce obvious resistance, and the indicating line cannot enter the shell 1; When the shell 1 appears deformation and damage caused by sealing failure, the gas in the shell 1 from the air outlet pipe 36 will directly flow out from the leakage point, at this time, the upward movement of the push rod 41 will not be resisted, the indicating line on the push rod 41 will smoothly enter the shell 1, and the push rod 41 can completely penetrate into the shell 1; At this time, the microseismic sensor 91 is screwed on the microseismic connector 53, and when some of the microseismic connectors 53 are not installed with the microseismic sensor 91, the microseismic connector 53 screwed with the microseismic sensor 91 is affected by the outside of the microseismic sensor 91 and is clamped on the outer wall of the shell 1, and the microseismic connector 53 without the microseismic sensor 91 is not affected by the microseismic sensor 91 and is screwed into the shell 1; After the push rod 41 is sent open, the spring 43 in the compressed state is pushed down by the lifting plate 42 under the action of the elastic force, the driven gear 73 is reversed, and the fixed box 31 retracts the gas in the shell 1 and the side pipe 35 into the fixed box 31 through the one-way air inlet pipe 34, at this time the moving shaft 55 is pulled back to the reset position in the reverse direction, and then drives the microseismic connector 53 to move in the reverse direction, the microseismic connector 53 screwed with the microseismic sensor 91 is affected by the microseismic sensor 91 and cannot enter the shell 1, and the microseismic connector 53 without the microseismic sensor 91 is pulled back into the shell 1 under the magnetic attraction between the microseismic connector 53 and the moving iron plate 52, and the microseismic connector 53 drives the iron sheet 61 to reverse by the magnetic attraction with the iron sheet 61, and the driven gear 73 drives the iron sheet 61 to reset, and the stop bar 63 is fixed on the rear end of the iron sheet 61, and in the process of the lifting plate 42 moving down, the pressure rod 85 moves down, when the pressure rod 85 contacts with the guide block 84, the knocking rod 82 is pushed to move back, and then knocks on the last vibration of the roadway, when the microseismic sensor 91 does not detect the vibration, it means that the microseismic sensor 91 is damaged.
