Technical Field

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

[0002] Groundwater level measurement devices are important tools for monitoring groundwater resources and play a significant role in protecting them. Groundwater is an important resource on Earth, and as the main source of drinking water in arid regions, it is the only reliable source. Therefore, the protection of groundwater is of great importance.

[0003] Groundwater level detection devices are a type of water level detection device. Currently, most water level detection devices on the market use traditional measurement methods, which involve manually lowering a measuring rope into the ground and recording the water level mark on the rope. This method has problems such as large errors and inaccurate measurement. At the same time, traditional water level detection devices cannot detect water quality issues and cannot determine whether groundwater is polluted, requiring secondary sampling and adding to the operational steps.

[0004] Therefore, there is an urgent need to provide a groundwater level measurement device to solve the above problems. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing groundwater level detection devices use traditional measurement methods, which have large errors and are inaccurate; at the same time, they cannot determine whether groundwater is polluted, requiring secondary sampling, which is cumbersome.

[0008] The above technical solution allows the device to be moved to a suitable position and transferred in any direction using omnidirectional wheels.

[0009] The present invention is further configured such that: the driving device includes a motor fixedly connected to the housing, the output shaft of the motor is fixedly connected to a worm gear, the lower end of the worm gear is threadedly connected to a turbine, and a rotating shaft is fixedly connected inside the turbine.

[0010] Through the above technical solution, the motor starts and drives the worm gear to rotate, the worm gear and the turbine gear drive each other, and the rotating shaft rotates to drive the measuring device to perform measurement.

[0011] The present invention is further configured such that: the measuring device includes a circular plate fixedly connected to a rotating shaft; a connecting column is fixedly connected to the side of the circular plate away from the driving device; the side of the connecting column away from the circular plate is rotatably connected to a housing; a nylon rope is slidably connected to the connecting column; a cylinder is fixedly connected to the lower end of the nylon rope; a cavity is opened inside the cylinder; a float is provided at the lower end of the cylinder; a connecting shaft is fixedly connected to the upper end of the float; a connecting piece is fixedly connected inside the cavity; the connecting shaft and the connecting piece are slidably connected through each other; and an electrode plate is fixedly connected to the top end of the connecting shaft.

[0012] With the above technical solution, the circular plate is fixedly connected to the rotating shaft. When the rotating shaft rotates, the circular plate rotates simultaneously, and the connecting column fixedly connected to the circular plate rotates. The nylon rope on the connecting column is lowered or wound up. When the float at the lower end of the nylon rope does not enter the water, the electrode plate at the upper end of the connecting shaft is connected to the connecting plate inside the cylindrical cavity under the influence of gravity. The motor in the drive device rotates, continuously lowering the float. When the float enters the water, the float is affected by buoyancy, and the electrode plate at the upper end of the connecting shaft disengages from the connecting plate.

[0016] With the above technical solution, after the device is moved to the position, the rotating plate is rotated to a suitable angle, the pneumatic slide bar is moved to a suitable position in the pneumatic slide groove, and then the ground nail is driven into the ground to maintain stability.

[0017] The present invention is further configured such that: the stabilizing device includes a support plate fixedly connected to the outer surface of the cylindrical tube, a spring fixedly connected to the upper end of the support plate near the locking block, baffles provided on both sides of the spring, an inclined block fixedly connected to the upper end of the spring, a slot opened on the surface of the baffle, a handle fixedly connected to the side of the inclined block near the slot, and the handle and the slot being slidably connected through.

[0018] With the above technical solution, after the measurement and sampling are completed, the pneumatic slide bar is retracted into the pneumatic slide groove, and the locking block at the rear end of the rotating plate is locked into the inclined block. The inclined block moves down under the action of the spring, locking the locking block. When it is necessary to remove it, grip the handle fixed on the inclined block, move the handle down along the groove, and remove the rotating plate.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model, through the design of a simple driving device and measuring device, allows the float at the lower end of the nylon rope to connect with the electrode plate at the upper end of the connecting shaft to the connecting plate inside the cylindrical cavity under the influence of gravity when the float is not in the water. At this time, the motor in the driving device rotates, and the float continues to descend. When the float enters the water, the electrode plate at the upper end of the connecting shaft separates from the connecting plate under the influence of buoyancy. At this time, the motor is de-energized, and the connecting column stops rotating, ensuring the accuracy of the measurement and minimizing the error.

[0021] 2. This utility model designs a water quality testing device. When a conical weight enters the water, groundwater enters through a circular through-hole. The small cylinder telescopic shaft retracts, and the rack fixedly connected to the telescopic shaft rises. The rack and gear engage, and the detection plate, which is away from the rack, moves downward. The detection plate contacts the groundwater to test the water quality, avoiding secondary sampling and making operation convenient. Attached Figure Description
