[0040] As shown in Figures 1 to 5 , Figure 7As shown, the bottom end of the box 2 is fixed with a chassis 6; the inner wall of the chassis 6 is fixed with a spade 61, and the spade 61 is located on one side of the overflow port 21; the middle bottom end of the chassis 6 is fixed with a nail 62, and the nail 62 is provided with three groups; when the box 2 is inserted into the deep hole, in order to reduce the falling of the surface soil of the deep hole, so as to block the multiple groups of overflow ports 21 and affect the detection of the water level, therefore, the chassis 6 is fixed at the bottom end of the box 2, during the process of inserting the box 2 into the deep hole, the spade 61 fixed on the inner wall of both sides of the chassis 6 will shovel the soil on the surface of the deep hole, so that the surface of the deep hole is in a smooth state, thereby reducing the situation that the soil falling blocks the multiple groups of overflow ports 21, in addition, the three groups of nails 62 at the bottom end of the chassis 6 are inserted into the soil at the bottom end of the deep hole, thereby enhancing the stability of the buried box 2.

[0041] As shown in Figures 1 to 5 , Figure 8 , the inner wall of the box 2 is slidingly connected with an extrusion rod 7; the surface of the extrusion rod 7 is fixed with a third elastic member 71 at one end, and the other end of the third elastic member 71 is fixed to the inner wall of the box 2; a first inductor 72 is installed in the box 2, and the first inductor 72 is located at the corresponding position of the extrusion rod 7; a warning light 73 is installed at the top end of the liquid level rod 13, and the warning light 73 is signal connected with the first inductor 72; when the water overflows in the measuring box 1, with the rising of the underground water level of the tunnel, the first float 12 drives the second float 14 on the liquid level rod 13 to slide, when the inner wall of the measuring box 1 slides to the extrusion rod 7 on the second float 14, the second float 14 extrudes the extrusion rod 7, the extrusion rod 7 is extruded into the inner wall of the measuring box 1, the third elastic member 71 is contracted under stress, the extrusion rod 7 is subsequently extruded to trigger the first inductor 72, the first inductor 72 is a pressure sensor, after being extruded, the first inductor 72 sends a signal to the warning light 73, the warning light 73 issues an alarm in real time, the alarm is issued every two to three limit blocks 3 minutes, and the yellow light flashes, until the staff turns off the alarm, thereby playing a role of warning the staff of the water level warning.

[0042] As shown in Figures 1 to 5 , Figure 9As shown, the inner wall of the measuring box 1 is fixed with a fixed block 8; the inner wall of the fixed block 8 is slidingly connected with a sliding ring 81; the inside of the fixed block 8 is installed with a second inductor 82, and the second inductor 82 is signal connected with the warning light 73; when the water level of the tunnel underground continues to rise, the water level has passed the position of the extrusion rod 7, and as the water level continues to rise, the second floating block 14 is floated to the position of the fixed block 8, the second floating block 14 will slide the sliding ring 81 to the inside of the fixed block 8, the sliding ring 81 will extrude the second inductor 82, the second inductor 82 is also a kind of pressure sensor, the second inductor 82 sends a signal to the warning light 73 after being extruded, and the warning light 73 issues an alarm again, at this time, the warning light 73 is not stopped and flashes red light, which plays a role of warning the water level of the tunnel is too high.

[0043] The overflow port 21 is arc-shaped; one end of the overflow port 21 is large, and the other end of the overflow port 21 is small; when the box 2 is buried in the tunnel deep hole, the mixed foreign matter flows to the overflow port 21, and part of the foreign matter is filtered by the arc-shaped inner wall of the overflow port 21, and when the water flow passes through the overflow port 21, the situation of being blocked by foreign matter is reduced through the large end of the overflow port 21, and the water is slowly overflowed into the measuring box 1 through the small end of the overflow port 21 to realize water level monitoring.

[0044] Example two

[0045] As shown in Figure 11 Comparative example one, another embodiment of the present application is: the surface of the shovel 61 is hinged with a guide plate 9; the surface of the shovel 61 is fixed with an elastic block 91, and the elastic block 91 is fixed to the surface of the guide plate 9; when the box 2 is inserted into the tunnel deep hole, the shovel 61 continuously removes the soil on the inner wall of the deep hole, in order to reduce the adhesion of the soil on the shovel 61, the guide plate 9 is hinged on the inner wall of the shovel 61, and the elastic block 91 is fixed between the guide plate 9 and the shovel 61 to support, in the process of shoveling the soil by the shovel 61, the guide plate 9 is inclined, so that the soil is shovelled by the shovel 61 and slides on the surface of the guide plate 9, and finally is extruded by the elastic block 91 to form an inclined turning point and falls, thereby reducing the adhesion of the soil on the shovel 61.

[0046] In the working process, when the water level in the tunnel is monitored, a group of deep holes similar in size to the water level monitoring equipment is first punched in the tunnel to be monitored. The anti-blocking assembly is first inserted into the deep hole, and then the measuring box 1 is slidably inserted into the inside of the anti-blocking assembly until the measuring box 1 is inserted into the deep end of the anti-blocking assembly. The water under the tunnel enters the anti-blocking assembly during monitoring, and then enters the inside of the measuring box 1 from the multiple overflow holes of the measuring box 1. As the water level in the measuring box 1 rises, the first floating block 12 on the baffle 11 slides on the inner wall of the measuring box 1, and the liquid level rod 13 at the top of the first floating block 12 slides with the second floating block 14. The liquid level rod 13 is provided with a scale line, which can facilitate the staff to check the water level under the tunnel. The water level in the tunnel is monitored, and the multiple overflow holes of the measuring box 1 effectively reduce the situation that the overflow holes are blocked by foreign matter. The anti-blocking assembly enhances the effect of preventing the overflow holes from being blocked. At the same time, the two baffles 11 are fixed on the inner wall of the measuring box 1 and located at the bottom end of the first floating block 12. There is a gap between the two baffles 11. When the water overflows into the inside of the measuring box 1, the first floating block 12 can float up conveniently. When the tunnel water level monitoring equipment is buried, the sleeve box 2 is first inserted into the corresponding deep hole punched. The measuring box 1 is slidably inserted into the inner wall of the sleeve box 2 until the bottom end of the inner wall of the sleeve box 2. The water under the tunnel slowly overflows into the inside of the sleeve box 2 from the multiple overflow openings 21. There is a space between the sleeve box 2 and the measuring box 1. The water will remain in the space between the sleeve box 2 and the measuring box 1. The small foreign matter mixed with the water entering the sleeve box 2 will also accumulate between the sleeve box 2 and the measuring box 1, reducing the situation that the overflow holes are blocked by foreign matter. At the same time, if the water level continues to rise, it will slowly enter the inside of the measuring box 1 from the overflow holes of the measuring box 1, driving the first floating block 12 to float on the inner wall of the measuring box 1. If the water level recedes after rising, the water in the sleeve box 2 will flow out from the two leakage openings 22 and the multiple overflow openings 21 opened at the bottom end of the sleeve box 2, playing a role in monitoring the water level under the tunnel. Part of the foreign matter is filtered by the arc-shaped inner wall of the overflow opening 21. When the water flows over the overflow opening 21, the large end of the overflow opening 21 is lowered to reduce the situation that the overflow opening is blocked by foreign matter. The small end of the overflow opening 21 slowly overflows into the inside of the measuring box 1 to realize water level monitoring. When the measuring box 1 is inserted into the bottom end of the sleeve box 2, the measuring box 1 will extrude the limiting slide rod 31 in the inside of the limiting block 3. The limiting slide rod 31 slides in the inner wall of the limiting block 3 and extrudes the first elastic member 32. After the bottom end of the measuring box 1 is correspondingly clamped between the two limiting blocks 3, the first elastic member 32 is elastically reset, extruding the front end of the limiting slide rod 31 out of the inside of the limiting block 3 and inserting it into the corresponding clamping groove of the measuring box 1, playing a role in stably assembling the measuring box 1. The two mudguards 4 slide on the inner wall of the sleeve box 2. When the sleeve box 2 is inserted into the deep hole, the four second elastic members 43 cooperate with the sliding insertion rod 42 to slide the inner wall of the sleeve box 2. The two mudguards 4 at the bottom end of the fixed frame 41 are misaligned with the multiple overflow openings 21 opened in the sleeve box 2, realizing the blocking of the multiple overflow openings 21.So in the case of the set box 2 slide deep hole, sundries are blocked in the outer wall of the set box 2, and when the set box 2 is inserted into the bottom end of the deep hole, the measuring box 1 is inserted into the inner wall of the set box 2, and the two groups of pressing blocks 44 fixed on the measuring box 1 are pressed on the fixed frame 41. When the set box 2 is clamped by the limiting block 3, the two groups of pressing blocks 44 press the two groups of fender plates 4 at the bottom end of the fixed frame 41, and the two groups of fender plates 4 slide down the inner wall of the set box 2 at the same time, so as to realize the penetration of the multiple overflow ports 21, and the water slowly overflows into the inside of the measuring box 1, which plays a role in controlling and blocking the multiple overflow ports 21. The multiple rotating rods 5 are connected to the inner wall of the set box 2 by the torsional spring, and the blocking plate 51 fixed on the surface of the rotating rod 5 blocks the overflow port 21. When the water level is too high, the water pressure will open the blocking plate 51, so that the water overflows into the inside of the set box 2 to realize monitoring. If a small amount of foreign matter extrudes the blocking plate 51, it will be blocked by the torsional force of the torsional spring and the blocking plate 51, so as to reduce the foreign matter into the inside of the set box 2. The bottom frame 6 is fixed at the bottom end of the set box 2. During the process of inserting the set box 2 into the deep hole, the spade 61 fixed on the inner wall of the bottom frame 6 will shovel the soil on the surface of the deep hole, so that the surface of the deep hole is smooth, thereby reducing the situation that the soil falls and blocks the multiple overflow ports 21. The guide plate 9 is hinged to the inner wall of the spade 61, and the elastic block 91 is fixed between the guide plate 9 and the spade 61 to support. During the process of shoveling the soil by the spade 61, the guide plate 9 is inclined, so that the soil shovelled by the spade 61 slides along the surface of the guide plate 9, and is finally extruded by the elastic block 91 to form an inclined inflection point and fall, thereby reducing the adhesion of the soil at the spade 61. In addition, the three groups of nails 62 at the bottom end of the bottom frame 6 are used to penetrate into the soil at the bottom end of the deep hole, so as to enhance the stability of the set box 2 buried in the soil. With the rising of the underground water level of the tunnel, the first floating block 12 drives the second floating block 14 on the liquid level rod 13 to slide. When the second floating block 14 slides to the extrusion rod 7 on the inner wall of the measuring box 1, the second floating block 14 extrudes the extrusion rod 7, the extrusion rod 7 is extruded into the inner wall of the measuring box 1, and the third elastic member 71 is contracted under stress. The extrusion rod 7 then extrudes and triggers the first inductor 72. The first inductor 72 is a kind of pressure sensor. After being extruded, the first inductor 72 sends a signal to the warning light 73. The warning light 73 issues an alarm in real time, and the alarm is issued once every two limiting blocks 3 minutes, and the yellow light flashes until the staff turn off the alarm. The warning light 73 plays a role in warning the staff of the water level warning. With the continuous rising of the water level, the second floating block 14 floats to the position of the fixed block 8, the second floating block 14 pushes the sliding ring 81 to the inside of the fixed block 8, and the sliding ring 81 extrudes the second inductor 82. The second inductor 82 is also a kind of pressure sensor. After being extruded, the second inductor 82 sends a signal to the warning light 73, and the warning light 73 issues an alarm again. At this time, the warning light 73 issues an alarm without stopping, and the red light flashes, which plays a role in warning that the water level of the tunnel is too high.
