Description

Technical Field

[0001] The utility model relates to the technical field of surveying, in particular to a rock and soil survey water level measuring device. Background Art

[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site according to the requirements of the construction project. During the investigation process, surveyors often need to measure the groundwater level in the rock and soil. Currently, water level measuring devices are mostly used for this purpose. In actual use, they have the advantages of simple operation, stable structure and accurate measurement.

[0003] The prior art discloses a water level measuring device for geotechnical investigation with announcement number CN217637558U, which includes a base plate, a wire rope retracting and releasing device, a wire rope positioning assembly, a mounting frame, a steel casing, a wire rope body, a measuring head assembly, a guide rail, a sliding hole, a slider, a connecting block, a limit hole, a threaded hole, a knob, a screw, a lead weight, a tension sensor, a connecting rod, a buoyancy ball and a connecting ring. When in use, the wire rope retracting and releasing device is operated to drive the wire rope body to release the wire, and the wire rope body is driven to descend. The lead weight provided mainly plays a traction role during descent. When the lead weight descends to the lower part of the water surface, the buoyancy ball generates an upward force due to the buoyancy of the water. The buoyancy ball acts on the tension sensor through the connecting rod, causing a pulling force to be generated. The value of the tension sensor changes, and it should be noted that the tension sensor is connected to the external controller through a wire, and the wire is placed in the steel casing together when the rope body descends. When the value of the tension sensor changes, it means that the measuring head assembly has reached the water surface position, and then the rope body is observed. The outer wall of the rope body is provided with a scale line, and the value of the position parallel to the outer surface of the upper end of the substrate is read, and then the thickness of the substrate is cut off with the read value; a rope positioning assembly is set, and the rope body passes through the limit hole. The limit hole is set to facilitate the vertical drop of the rope body to avoid the deviation of the rope body from contacting the inner wall of the steel casing, thereby increasing the accuracy of the measurement, and the position of the limit hole can be adjusted by the slider set.

[0004] In the above-mentioned utility model, the height adjustment of the lead sinker can be completed by reeling in and out the winding rope body. During the unwinding process of the rope body, it can enter the inside of the well body. The surface of the rope body is easily contaminated with impurities. At this time, reeling in the rope body may cause the impurities to crush the reeled rope body, which brings hidden dangers to the protection of the rope of this utility model. At the same time, the buoyancy ball is placed outside the air. When there are holes on the surface of the buoyancy ball, groundwater can enter the interior of the buoyancy ball through the holes, which will affect the floating use of the buoyancy ball and reduce the practicality of this utility model.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0018] (1) The utility model adopts an installation pipe and a water storage tank. When the geotechnical survey water level measuring device is actually used, the controller is used to make the output end of the forward and reverse motor drive the winding roller to rotate, the winding roller can unwind the rope, and the lead pendant can move downward. When the buoyancy ball contacts the water surface, the tension sensor can be stretched through the connecting rod, and the tension sensor can send a signal to the controller.

During this process, the piston and the positioning plate can squeeze the telescopic spring. When the piston moves to the appropriate position, the upper set of opening and closing valves is closed. When the piston is reset, it indicates that there are holes on the surface of the buoyancy ball. When the piston does not move, it indicates that there are no holes on the surface of the buoyancy ball.

When the buoyancy ball 7 contacts the water surface, the tension sensor can be stretched through the connecting rod 6. The tension sensor can send a signal to the controller. The controller then makes the output end of the forward and reverse motor 10 drive the winding roller 3 to rotate in the opposite direction to rewind the rope 4. At the same time, the water level can be known through the scale mark on the surface of the rope 4. The controller also makes the electric heater 19 , the driving motor 20, the fan 21 and the pump 25 start working, the pump 25 can spray the water in the water tank 17 through the water spray pipe 26, and the sprayed water can flush the rope 4. The output end of the driving motor 20 drives the gear 22 to rotate. Since the gear 22 and the outer gear ring 24 are meshed with each other, the rotating gear 22 can push the outer gear ring 24 to rotate, and the rotating outer gear ring 24 can drive the rotating tube 23 to rotate. The rotating rotating tube 23 can scratch the surface of the rope 4 through the brush. The fan 21 can blow the hot air near the electric heater 19 to the rope 4, which can The surface of the rope 4 is dried, and the water can enter the interior of the water tank 17 through the water inlet pipe 27. Through the provided installation pipe 16 and the water tank 17, the impurities on the surface of the rope 4 can be cleaned during the winding process, which provides a guarantee for the protection of the rope 4 of the geotechnical survey water level measuring device. At the same time, before the actual use of the geotechnical survey water level measuring device, the interior of the buoyancy ball 7 can be inflated through the air inlet pipe 8. The gas can enter the interior of the transparent cylinder 30 through the air guide pipe 9. The gas can push the piston 33, and the piston 33 can drive the T-shaped rod 32 to move right. This process In the figure, the piston 33 and the positioning plate 31 can squeeze the telescopic spring 34. When the piston 33 moves to the appropriate position, the upper set of on-off valves 29 is closed. When the piston 33 is reset, it indicates that there are holes on the surface of the buoyancy ball 7. When the piston 33 does not move, it indicates that there are no holes on the surface of the buoyancy ball 7. The scale markings on the surface of the transparent tube 30 can be used to know the specific position of the piston 33.
