The groundwater level is the most direct data reflecting the state of groundwater. It is a very critical data in groundwater level monitoring, groundwater resource assessment and calculation. When using the monitoring device in the prior art, the probe is first placed in the water level monitoring well, and then the construction personnel need to manually lay out the line and slowly move the probe downward. When the contact of the probe touches the water surface, the sounder of the receiving system will emit a buzzer, and the depth size on the steel ruler can be read at this time; However, since most groundwater is in a flowing state, it is difficult to continuously and accurately monitor the water level of the crests and troughs of the waves generated by the flowing groundwater when simply using a steel ruler and a water level sensor to touch the water level and emit a buzzing sound to monitor the water level.

[0012] Compared with the prior art, the present invention has the following significant advantages: First, when the present invention needs to monitor the water level of groundwater caused by waves, the trapezoidal block can be pressed to make its fixed plate drive the plug rod under the action of spring 2 to move the plug rod in the direction of the reel, so that the plug rod is inserted into the slot. After the plug rod is inserted into the slot, when the flow rate is fast and waves are generated, under the action of the buoyancy plate, the buoyancy plate will drive the water level sensor to float up with the surge. At this time, the steel ruler on the reel will be loose. When the reel is not subjected to gravity, the rack will recover its deformation downward through the action of spring 1 and drive the gear ring to rotate. The rotation of the gear ring drives the rotating rod to rotate. The rotation of the rotating rod can make the plug rod drive the reel to rotate, thereby tightening the steel ruler on the reel, so that the water level at the wave peak can be measured more accurately, and the accuracy of groundwater level monitoring can be improved.

When the baffle plate 2 rotates, the convex block arranged on the inner wall of the protective shell can be used to squeeze the spherical rod. Under the action of the reset spring, the spherical rod can reciprocate and vibrate the protective shell. When the rotating shaft rotates, the vertical rod is driven to rotate by the bevel gear. The vertical rod drives the rotating filter cylinder to rotate through the action of the pulley and the belt. The rotating rotating filter cylinder cooperates with the action of the bristles to improve the protection effect of the water level sensor, thereby improving the accuracy of water level monitoring. Third: When the present invention is protecting the water level sensor, the adapter block arranged inside the sand discharge pipe will drop inside the hollow convex ring when the weight of the residual sand inside the protective shell is greater than the elastic force of the tension spring. After dropping, a certain gap will be generated between the surface of the adapter block and the inner wall of the hollow convex ring, and the sand will be discharged along the sand discharge pipe, which can prevent the internal sand from being lifted up and clogging the detection hole of the water level sensor, thereby improving the accuracy of groundwater level monitoring.
[0013] The invention solves the problem that the existing method of simply using a steel ruler and a water level sensor to contact the water level and emit a buzzing sound to monitor the water level is difficult to continuously and accurately monitor the peaks and troughs of the flowing groundwater level, and that impurities such as sand particles may be washed away by the water flow, which may easily clog the detection hole of the sensor and affect the accuracy of the measurement result.

A fixing frame 903 is fixedly connected to the inner wall of the sand discharge pipe 901, and a through hole is opened on the upper surface of the fixing frame 903. A movable rod 904 is slidably connected to the inner wall of the through hole, and a check plate 908 is fixedly connected to the order of the movable rod 904.

[0024] like Figure 1 and 2 As shown, a controller 11 is fixedly installed on the upper surface of the substrate 3, a fixing ring 12 is fixedly connected to the inner wall of the substrate 3, and a steel ruler 7 is arranged inside the fixing ring 12. The fixing ring 12 can limit the steel ruler 7 to avoid shaking of the bottom protective mechanism and the water level sensor 13.
[0025] The specific working method is: when using, firstly, the device is erected above the monitoring channel 1 through the installation rod 2, and the direction is adjusted according to the flow direction of the groundwater. At this time, the handle driving rod 501 is turned to drive the reel 6 to rotate, and the steel ruler 7 is released. The steel ruler 7 drives the water level sensor 13 inside the protection component 8 to enter the monitoring channel 1 to monitor the internal groundwater level. When the water level sensor 13 contacts the groundwater, the controller 11 displays the water level depth. At this time, the buoyancy board 10 floats on the water surface, and the position of the buoyancy board 10 is flush with the detection hole of the water level sensor 13; When it is necessary to adaptively monitor the crest of groundwater, the trapezoidal block 513 can be pressed to make the fixed plate 504 drive the rod 505 to move in the direction of the reel 6 under the action of the spring 2 510, so that the rod 505 is inserted into the slot 503. After the rod 505 is inserted into the slot 503, when the flow rate is fast and waves are generated, under the action of the buoyancy plate 10, the buoyancy plate 10 will drive the water level sensor 13 to float up with the surge. At this time, the steel ruler 7 on the reel 6 will become loose, and the reel 6 will be free from gravity, and the rack 509 will pass through the reel 6. The spring 508 recovers the deformation downward and drives the gear ring 506 to rotate. The rotation of the gear ring 506 drives the rotating rod 502 to rotate. The rotation of the rotating rod 502 can make the plug rod 505 drive the reel 6 to rotate, thereby tightening the steel ruler 7 on the reel 6, which can more accurately measure the water level at the peak and improve the accuracy of groundwater level monitoring. When a trough occurs, the working principle is similar. The buoyancy plate 10 drives the protection mechanism and the water level sensor 13 to descend, so that the reel 6 rotates, the gear ring 506 rotates, drives the rack 509 to rise, and the spring 508 is stretched. During continuous monitoring, the water level sensor 13 needs to be placed in the groundwater. The protective shell 801 and the rotating funnel 807 can protect the water level sensor 13 to avoid being blocked by mud and sand. The baffle plate 1 814, baffle plate 2 817, guide plate 1 815 and guide plate 2 818 provided on the rotating shaft 812 can rotate the baffle plate 1 814 and baffle plate 2 817 under the action of water flow through the flow hole 802 provided on the protective shell 801 during the flow of groundwater, thereby driving the bristles 816 on the baffle plate 1 814 to achieve the protection of the protective shell 801 and the rotating funnel 807. The reciprocating brushing of the rotary filter cylinder 807 can cooperate with the protrusion 803 set on the inner wall of the protective shell 801 to squeeze the spherical rod 819 when the baffle plate 817 rotates. The spherical rod 819 can reciprocate and vibrate the protective shell 801 under the action of the reset spring 820. When the rotating shaft 812 rotates, the vertical rod 810 is driven to rotate through the bevel gear 811. The vertical rod 810 drives the rotation of the rotary filter cylinder 807 through the action of the pulley 808 and the belt 809. The rotating rotary filter cylinder 807 cooperates with the action of the brush 816 to improve the protection effect of the water level sensor 13, thereby improving the accuracy of water level monitoring; When protecting the water level sensor 13, the residual sand inside the protective shell 801 will settle to the top of the adapter block 910 due to gravity. When the weight of the residual amount is greater than the elastic force of the tension spring 905, the adapter block 910 will descend inside the hollow convex ring 902. After descending, a certain gap will be created between the surface of the adapter block 910 and the inner wall of the hollow convex ring 902, and the sand will be discharged along the sand discharge pipe 901, thereby preventing the internal sand from being lifted up and clogging the detection hole of the water level sensor 13. When the adapter block 910 descends, the movable rod 904 will drive the check plate 908 to descend at the same time, sealing the top of the sand discharge pipe 901 to prevent external sand and water from flowing back into the protective shell 801, thereby improving the protection effect.
