[0013] 1. The utility model is convenient for evenly storing the ruler by installing a U-shaped frame. First, the ruler is placed in the U-shaped frame, and the user then uses a rocker to rotate the wire wheel to retract the released ruler, and then the wireless remote control starts the motor to drive the screw rod to move. At the same time, the screw rod drives the ruler on the U-shaped frame to move left and right through the nut. The retracted ruler will be evenly distributed on the wire wheel driven by the moving U-shaped frame, avoiding chaotic cross-entanglement of the ruler on the wire wheel, which makes it impossible to pull the ruler smoothly when it is used next time.

First, the user pulls the clamp through the handle, and the clamp will compress the spring to shrink to both sides. Then the ruler is placed in the cotton brush, and the handle is released to release the pressure on the spring, so that the spring pushes the clamp to quickly reset and clamp the ruler. Then the retracted ruler will be cleaned of water stains and dirt by the cotton brush and then wound around the wire wheel, so as to prevent water stains and dirt from being attached to the ruler pile for a long time and corroding the surface of the ruler, thereby protecting the ruler from corrosion and damage and improving the service life of the pit foundation detection device.

In the pit foundation engineering, the change of the groundwater level will have an important impact on the stability and safety of the engineering. By detecting the change of the groundwater level through the groundwater level detector, measures can be taken in time to adjust the engineering design and construction plan. The wire wheel 2 is rotated by the rocker 19, so that the ruler 3 drives the detection head 4 down into the underground pit. When the detection head 4 contacts the water level, The internal sensor will be triggered to emit a prompt sound. The user can observe the scale on the ruler 3 to obtain the water level drop. However, when the ruler 3 is retracted, the ruler 3 is usually chaotically cross-entangled on the reel 2, which is not conducive to the next use of the groundwater level meter.

First, the ruler 3 is placed in the U-shaped frame 9, and the user then uses the rocker 19 to rotate the reel 2 to retract the released ruler 3, and then the wireless remote control starts the motor 6 to drive the screw rod 7 to move. At the same time, the screw rod 7 will drive the ruler 3 on the U-shaped frame 9 to move left and right through the nut 8. The retracted ruler 3 will be evenly distributed on the reel 2 driven by the moving U-shaped frame 9, avoiding the ruler 3 being chaotically cross-entangled on the reel 2, resulting in the ruler 3 being unable to be pulled smoothly when used next time, keeping the ruler 3 tidy and running smoothly, and improving the working efficiency of the pit foundation measuring device.
