A water pump and an explosion-proof switch are installed in the cavity of the main body 10. A water suction pipe 11 and a liquid level gauge 12 are fixedly installed at the bottom of the main body 10. The water suction pipe 11 is connected to the water inlet of the water pump. The liquid level gauge 12 and the water pump are both electrically connected to the explosion-proof switch signal. Specifically, a control panel should also be installed in the cavity of the main body 10, and the explosion-proof switch is electrically connected to the control panel signal. The liquid level gauge 12 can be a contact single-flange static pressure transmitter or an ultrasonic liquid level transmitter. The specific models and specifications are not restricted too much here. The liquid level threshold is set by the control panel to control the start and stop of the water pump. Another pipe is fixedly installed at the output port of the water pump for discharge. The water level is controlled by discharging the water at the monitoring position to the specified position. This is an existing well-known technology and will not be elaborated here.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, two groups of support rod assemblies for supporting the main body 10 are symmetrically arranged on the outside of the main body 10, and the support rod assembly includes a support plate 20, a first adjusting screw 21, a cushion block 22 and a second adjusting screw 23. The support plate 20 is movably connected to the main body 10 through the second adjusting screw 23 and the height is adjusted. Two cushion blocks 22 are symmetrically arranged at the bottom of the support plate 20. The wall surface of the support plate 20 is threadedly connected to the two first adjusting screws 21. The two first adjusting screws 21 are rotatably connected to the corresponding cushion blocks 22 and the positions of the cushion blocks 22 are adjusted. The support plate 20 forms a rectangular plate structure. A threaded hole is opened on the top surface of the support plate 20 near the two ends. The first adjusting screw 21 is connected to the corresponding threaded hole. A bearing is installed on the top surface of the cushion block 22. An adjusting screw 21 is fixedly connected to the inner ring of the bearing. The support plate 20 is set to rotate the second adjusting screw 23 to push the support plate 20 down. The support plates 20 on both sides of the main body 10 are individually adjustable, so that the left and right inclination angles of the main body 10 can be adjusted. The first adjusting screw 21 is rotated to adjust the pads 22 at both ends of the same support plate 20, so that the front and rear inclination angles of the support plate 20 can be adjusted. The two sets of support rod assemblies on both sides of the main body 10 enable the main body 10 to adjust the installation height, that is, the height at which the main body 10 is placed at the detection position, or the main body 10 is placed in water, to ensure the vertical installation of the main body 10, and can adapt to the unevenness of the ground within a certain range, with stable support and strong adaptability, thereby ensuring the accuracy of the liquid level measurement by the liquid level meter 12.

[0027] like Figure 3As shown, the support rod assembly also includes a limit rod 24 and an ear plate 25. Two ear plates 25 are arranged on the same side wall of the main body 10. The support plate 20 is movably connected to one of the ear plates 25 through the limit rod 24. The second adjusting screw 23 is threadedly connected to the other ear plate 25. Another identical bearing is fixedly installed on the top surface of the support plate 20. The second adjusting screw 23 is fixedly connected to the inner ring of the bearing. A limit hole adapted to the limit rod 24 is penetrated through the top surface of the ear plate 25. The limit rod 24 is slidably connected to the limit hole. The lower end surface of the limit rod 24 is fixedly connected to the top of the support plate 20. The wall surface of the other ear plate 25 is provided with a The inner threaded hole, the second adjusting screw 23 is connected to the inner threaded hole, the second adjusting screw 23 and the limit rod 24 are symmetrically distributed on the center line of the support plate 20. Specifically, the ear plate 25 is a rectangular plate, and the ear plate 25 can be fixed to the main body 10 by welding. The limit rod 24 is limited by the ear plate 25, and the other ear plate 25 is used to limit the second adjusting screw 23 to ensure that when the second adjusting screw 23 is rotated, the second adjusting screw 23 can push the support plate 20 to slide vertically, and the support plate 20 will also drive the limit rod 24 to slide along the limit hole on the wall of the other ear plate 25, thereby ensuring the stability of the movement and thus ensuring the support effect on the main body 10.

[0028] like Figure 5 As shown, a plurality of anti-skid spikes 30 are fixedly connected to the bottom surface of the pad 22, and the lower end surfaces of the anti-skid spikes 30 are chamfered to form a tapered end. By providing the anti-skid spikes 30, the pressure of the pad 22 on the bottom surface is increased by utilizing the anti-skid spikes 30, thereby increasing the anti-skid effect of the pad 22, providing stronger support stability for the main body 10 and preventing it from sliding.

[0029] The length of the support plate 20 is greater than the width of the main body 10. The second adjusting screw 23 and the limit rod 24 are respectively located on both sides of the support plate 20. The design that the length of the support plate 20 is greater than the width of the main body 10 can ensure that the two pads 22 are respectively located on the front and rear sides of the main body 10, which provides better support stability for the main body 10 and prevents the main body 10 from tipping over. This is more beneficial for mines with a lot of mechanical vibrations.

[0030] The working principle of the utility model is as follows: when the second adjusting screw 23 is rotated, the second adjusting screw 23 can push the support plate 20 to slide vertically, and the support plate 20 will also drive the limiting rod 24 to slide along the limiting hole on the wall of the other ear plate 25 to adjust the height of the support plate 20. The support plates 20 on both sides of the main body 10 are adjustable separately, so that the left and right inclination angles of the main body 10 can be adjusted. The first adjusting screw 21 is rotated to adjust the pads 22 at both ends of the same support plate 20, so that the front and rear inclination angles of the support plate 20 can be adjusted. The two sets of support rod assemblies on both sides of the main body 10 enable the main body 10 to adjust the installation height to ensure that the main body 10 is in a vertical position.
