Description

Technical Field

[0001] This utility model belongs to the field of groundwater level measurement technology, and in particular relates to a groundwater level measurement device. Background Technology

[0002] Groundwater level measurement devices are crucial tools for monitoring groundwater dynamics. Their core function is to acquire real-time and accurate water level data to support water resource management and environmental protection. They are widely used in urban water supply scheduling, agricultural irrigation management, geological disaster early warning, and mine safety monitoring. They play an irreplaceable role in protecting water resources, maintaining the ecological environment, and promoting sustainable development. Furthermore, by continuously tracking groundwater level changes, they provide a scientific basis for optimizing water resource allocation and preventing over-exploitation, and play a key role in geothermal wells and deep well projects. With continuous technological advancements and the expansion of application areas, the performance and functions of groundwater level measurement devices will continue to improve and be perfected.

[0003] Compared with Chinese Patent CN222505552U, a groundwater level measuring device is disclosed, including a mounting base. Support legs are mounted on both sides of the mounting base via telescopic frames, and casters are mounted on the bottom of the support legs. A winding reel is mounted on the mounting base via a mounting frame, and a measuring cable is wound on the winding reel. A counterweight is mounted at the bottom of the measuring cable, and conductive plates are symmetrically arranged on both sides of the bottom of the counterweight. A first connecting wire and a second connecting wire are respectively connected to the conductive plates inside the measuring cable. A battery is installed between the first and second connecting wires. An ammeter and a first alarm are installed on the first connecting wire. A pressure gauge is installed in the middle of the bottom of the counterweight. A third connecting wire connects the pressure gauge to the battery. An instrument panel is installed on the third connecting wire in conjunction with the pressure gauge, and a second alarm is installed in conjunction with the instrument panel. This allows for flexible adjustment during installation and enables simultaneous measurement of water level and depth.

[0004] However, the aforementioned patent requires measurement to be performed across the top of the wellhead, which reduces the flexibility and applicability of its use. Furthermore, its limited storage size and large space occupation significantly impact transportation and storage. Therefore, a new device needs to be designed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 A groundwater level measuring device includes a lifting assembly for suspending and lifting to measure groundwater level, and a chassis assembly for supporting movement and power supply. One end of the chassis assembly is provided with a support assembly for rotating outward and adjusting the suspension height vertically. The lifting assembly is installed on the top of the support assembly.

[0026] In this embodiment: the chassis assembly includes a moving mechanism, on which a battery 102 is mounted, and a push rod frame 105 is provided at one end of the moving mechanism; the moving mechanism includes a base plate 101, and four universal wheels 103 are evenly installed at the four corners of the bottom of the base plate 101, and a brake plate 104 is provided on the universal wheels 103; an anti-slip sleeve 106 is attached to the push rod frame 105, and the push rod frame 105 and the base plate 101 are riveted together; by holding the push rod frame 105, the base plate 101 is pushed to move under the support of the universal wheels 103, and the brake plate 104 is stepped on to fix it, and the battery 102 provides power to the servo motor 302 and the meter counter 306.

[0027] In this embodiment: the support assembly includes a fixed frame 201, a column 202 is slidably mounted on the top of the fixed frame 201, a locking pin 203 is mounted on the fixed frame 201, and a support mechanism is provided at the top of the column 202; the support mechanism includes a support beam 204, a support seat 205 is provided at one end of the support beam 204 near the column 202, and an outer suspension 206 is provided at the other end of the support beam 204 away from the column 202, with a support wheel 207 rotatably mounted in the middle of the outer suspension 206; the fixed frame 201 is made of hollow round tube material, and the column 202 is slidably mounted on the fixed frame 201. The column 202 is cylindrical and is welded together with the crossbeam 204. Under the support of the fixing frame 201, the column 202 is pulled upward to adjust the support height and rotate the column 202 so that the counterweight 304 is as close as possible to the center of the wellhead. Then the locking nail 203 is tightened to fix it. The support seat 205 supports the servo motor 302 to drive the winding wheel 301 to rotate and receive the cable 303. The crossbeam 204 supports the meter counter 306 and changes the direction of movement of the cable 303 through the support wheel 207 on the outer suspension 206.

[0028] In this embodiment: the lifting assembly includes a winding wheel 301, a servo motor 302 is provided on one side of the winding wheel 301, a cable 303 is wound on the winding wheel 301, the cable 303 passes through the meter counter 306, and a detection mechanism is provided at the end of the cable 303; the detection mechanism includes a counterweight 304, and two conductive plates 305 are symmetrically installed on the bottom of the counterweight 304; the servo motor 302 drives the winding wheel 301 to rotate and release the cable 303. Under the gravity pull of the counterweight 304, the cable 303 moves along the supporting beam 204, passes through the meter counter 306, and is guided by the support wheel 207 on the outer suspension 206, changing from horizontal movement to vertical descent. When the conductive plate 305 at the bottom of the counterweight 304 comes into contact with the water, the servo motor 302 stops, and the value displayed by the meter counter 306 at this time is the groundwater level.

[0029] Working principle: First, hold the push rod frame 105 and push the base plate 101 to the well edge with the support of the casters 103. Then, step on the brake plate 104 to fix it. Next, with the support of the fixing frame 201, pull the column 202 upward to adjust the support height and rotate the column 202 to bring the counterweight 304 as close as possible to the center of the well opening. Then, tighten the locking nail 203 to fix it. The battery 102 provides power, and the support base 205 supports the servo motor 302 to drive the winding wheel 301 to rotate and release the cable 303. 03 Under the pull of the counterweight 304, it moves along the supporting beam 204, passes through the meter counter 306, and is guided by the support wheel 207 on the outer suspension 206, changing from horizontal movement to vertical descent. When the conductive plate 305 at the bottom of the counterweight 304 comes into contact with the water, the servo motor 302 stops. At this time, the value displayed by the meter counter 306 is the groundwater level. When moving and storing, the above steps are reversed to rotate the supporting beam 204 above the base plate 101, which can reduce the space occupied.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
