Technical Field
[0001] The utility model provides a survey borehole water level measuring instrument, belonging to the technical field of water level measuring instruments. Background Art
[0002] A water level meter is an instrument for measuring water level and depth. It is suitable for narrow environments such as deep wells or pits. Drilling is required during geotechnical engineering surveys. In some areas with abundant groundwater resources, water will seep out of the holes. Workers can obtain the water level height through the water level meter and infer the more specific situation of the surrounding groundwater in turn.
[0003] The document with the prior art publication number CN217421148U provides a geotechnical engineering survey borehole water level measuring instrument. The device is equipped with a winding motor, which can be started when paying out or winding up the line. The winding motor can drive the winding shaft sleeve to rotate, and can effectively wind up or pay out the probe line, thereby improving the convenience of using the water level measuring instrument; by installing a front guide wheel and a rear guide wheel, when the probe line and the measuring head are placed in the hole and the line is paid out, the front guide wheel and the rear guide wheel can be fixed at the hole mouth, which can effectively guide and protect the probe line, avoid the probe line from continuously scratching the hole mouth and causing wear of the probe line, and improve the service life of the water level measuring instrument.
[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the front guide wheel and the rear guide wheel are fixed at the borehole mouth by inserting into the ground, which is difficult to perform plug-in operation in a construction environment with hard geology. In view of this, we propose a survey borehole water level measuring instrument. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an exploration borehole water level measuring instrument, which solves the technical problem of poor guidance effect of the probe line in the prior art and achieves the technical effect of rapid and stable descent of the probe line and the probe.

At the same time, the risk of contact between the measuring component and the hole wall is also reduced, and the measurement accuracy is improved. The setting of the limit component is fixed to the measuring component by magnetic attraction, which effectively ensures the stability of the measuring component.
[0012] Furthermore, the winding assembly includes a motor, which is mounted on the trolley. The output shaft of the motor is connected to a winding roller, and the winding roller is rotatably connected to the trolley.
[0013] Furthermore, the measuring component includes a connecting wire, one end of which is fixed on the winding roller, and the other end of which is electrically connected to a probe. A limit block is provided on the probe, and the connecting wire passes through the limit block and is connected to the probe.
[0014] By adopting the above technical solution, the motor drives the winding roller to rotate, thereby winding or releasing the connecting line, effectively controlling the height of the probe in the borehole.
[0015] Furthermore, the first adjustment component includes a screw rod, which is rotatably connected to the trolley, a slider is threaded on the screw rod, the slider is slidably connected to the trolley, a limit hole is provided on the slider, the limit block is slidably engaged with the limit hole, and a first positioning hole and a second positioning hole are provided on the slider.
[0016] By adopting the above technical solution, the slider is driven to move by rotating the lead screw, thereby effectively adjusting the longitudinal displacement of the measuring component.
[0017] Furthermore, the second adjustment component includes a sliding frame, which is slidably connected to the slider, and a guide hole is provided on the sliding frame. The connecting line passes through the guide hole, and the guide hole is used for guiding the lifting and lowering of the connecting line. The sliding frame is provided with a sliding rod, and a splint is provided on the sliding rod. The sliding rod is provided with a first elastic member, and one end of the first elastic member is fixedly connected to the sliding frame, and the other end is fixedly connected to the splint.
[0018] By adopting the above technical solution, the first elastic member drives the clamping plate to clamp the slider, thereby fixing the sliding frame. The setting of the guide hole makes the connecting line descend quickly and stably, ensuring that the probe descends quickly and smoothly.
[0019] Furthermore, a motorized roller and a driven roller are arranged on the sliding frame, and the motorized roller and the driven roller are distributed on both sides of the guide hole.
[0020] By adopting the above technical solution, the motorized roller and the driven roller effectively drive the connecting line to descend rapidly, while avoiding the problem of folding of the connecting line between the winding roller and the guide hole.
[0021] Furthermore, the limit assembly includes a sliding plate, which is slidably connected to the slider, a magnetic block is arranged on the sliding plate, a second elastic member is arranged on the sliding plate, one end of the second elastic member is fixedly connected to the slider, and the other end is fixedly connected to the sliding plate, and a limit pin is slidably arranged on the sliding plate.

The second elastic part is compressed, the limit pin is inserted into the second positioning hole, and the magnetic block is separated from the limit block, and the downward operation can be carried out.
