Abstract
Description
Technical Field
[0001] This utility model relates to the field of geotechnical engineering technology, specifically to a geotechnical engineering exploration water level measuring device. Background Technology
[0002] Geotechnical engineering is a new technical system established in the 1960s in civil engineering practice in Europe and America. Geotechnical engineering takes solving problems of rock and soil engineering, including foundations, slopes, and underground engineering, as its research object. The geotechnical engineering water level measuring device is a technical device used to accurately measure the groundwater level, mainly used in geotechnical engineering investigation.
[0003] The prior art, CN220602660U, discloses a geotechnical engineering exploration water level measuring device, belonging to the field of geotechnical engineering technology. It includes a mobile vehicle with a support frame fixedly connected to its upper surface. A rope is installed on the inner side of the support frame via a winding assembly. One end of the rope is fixedly connected to a connecting block. A float is located below the connecting block, and a second through hole is opened inside the float. A counterweight rod is installed inside the second through hole, and the upper end of the counterweight rod is fixedly connected to the lower part of the connecting block. Symmetrical grooves are formed on the upper surface of the float, and a support mechanism is slidably connected inside the grooves. This device can prevent the rope from swaying and stacking when measuring groundwater levels, thus avoiding the detection result being greater than the actual result, reducing detection errors, and improving the measurement accuracy of the device.
[0004] With the above configuration, the existing measuring device, through the interaction of the float below the connecting block, the counterweight rod inside the second through hole, the support mechanism inside the groove on the upper surface of the float, and the hinged rods on both sides of the connecting block, can prevent the rope from swaying and stacking when measuring groundwater level. This avoids the detection result being greater than the actual result, thereby reducing detection error and improving the measurement accuracy of the device. However, the existing measuring device has the following drawbacks during operation:
[0005] When the measuring device described in the prior art is in use, its float contacts the water surface, causing the counterweight rod to descend and be supported by the support plate. Since the well is deep, the workers cannot see the inside of the well. Because the rope is soft, the connection between the rope and the connecting block will bend, causing the rope to stack. This will make the detection results inaccurate and increase the measurement error. Utility Model Content
[0006] This utility model aims to provide a water level measuring device for geotechnical engineering investigation, mainly to solve the technical problem that in the existing technology, after the float comes into contact with water, the connection between the rope and the connecting block bends, which easily leads to inaccurate measurement results.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A geotechnical engineering exploration water level measuring device includes a mobile vehicle, a support frame, and a winding roller. The support frame is fixed to the upper surface of the mobile vehicle, and the winding roller is rotatably connected between the support frames. A rope is wound around the surface of the winding roller. A drive motor is fixed to one side of the support frame, and the output shaft of the drive motor passes through the support frame and is fixed to the winding roller. A float is fixed to one end of the rope, and an electrode sensor is fixed to the upper surface of the float. The detection end of the electrode sensor passes through the float and is slidably connected to it. A guide mechanism is fixed between the support frames.
[0009] The working principle and beneficial effects of this utility model:
[0010] 1. Working Principle: When it is necessary to measure the exploratory well, first push the mobile vehicle to push it directly above the exploratory well so that the floating roof is aligned with the exploratory well. Then adjust the limiting component so that the sleeve is disengaged from the limiting cylinder. Then start the controller so that the drive motor drives the winding roller to rotate, so that the rope is lowered and the floating roof moves into the interior of the exploratory well. When the electrode sensor on the floating roof comes into contact with the water surface, a reaction occurs inside and the signal is transmitted to the controller. The controller automatically controls the start and stop of the drive motor, and then the distance can be observed to complete the measurement.
[0011] 2. Beneficial effects:
[0012] Existing technology, through the interaction of a floating plate below the connecting block, a counterweight rod inside the second through hole, a support mechanism inside the groove on the upper surface of the floating plate, and hinged rods on both sides of the connecting block, can prevent the rope from swaying and stacking when measuring groundwater levels. This avoids the detection result being greater than the actual result, thus reducing detection errors and improving the measurement accuracy of the measuring device. However, in the existing measuring device, when the floating plate contacts the water surface, the counterweight rod descends and is supported by a support plate. Because the well is deep and workers cannot see inside, and because the rope is flexible, bending can occur at the connection point between the rope and the connecting block, leading to rope slippage. The current stacking phenomenon leads to inaccurate detection results and increases measurement errors. This solution addresses this by setting up a controller, drive motor, electrode sensor, guide mechanism, and limit components. The controller controls the start and stop of the drive motor, and the electrode sensor contacts the water surface and transmits its signal to the controller to control the start and stop of the drive motor. This allows for rapid stopping of the cable even when the inside of the exploration well is not visible, preventing the cable from bending due to excessive lowering and thus avoiding inaccurate measurement results. At the same time, the guide mechanism guides and protects the cable, and the limit mechanism prevents the floating table from shaking when the mobile vehicle is moved, avoiding technical problems such as damage to the floating table and electrode sensor.
[0013] Preferably, the guiding mechanism includes a support plate with a threading hole on its surface. A connecting sleeve is fixedly attached to the surface of the support plate, communicating with the threading hole. The rope passes through the threading hole and is slidably connected to the connecting sleeve. A limiting cylinder is fixedly attached to the lower surface of the connecting sleeve, communicating with the connecting sleeve. The rope passes through the limiting cylinder. A fixing cylinder is fixedly attached to the upper surface of the float, and the rope passes through the fixing cylinder and is fixedly connected to the float. A sleeve is slidably connected to the outer wall of the fixing cylinder, and the sleeve is slidably connected to the limiting cylinder. The inner wall of the limiting cylinder has symmetrical movable grooves, and a limiting component is installed inside the movable grooves. By setting up the guiding mechanism, the rope can be guided and protected, preventing lateral movement and swaying after the float is lowered into the exploration well.
[0014] Preferably, the limiting component includes a limiting rod slidably connected to a movable groove. A spring is fixedly connected to the inner wall of the movable groove, and the other end of the spring is fixedly connected to the limiting rod. A symmetrical limiting groove is formed on the inner wall of the sleeve, and a sliding plate is slidably connected to the inner wall of the limiting groove. The limiting rod is inserted into the limiting groove and abuts against the sliding plate. A push rod is fixedly connected to the side of the sliding plate away from the limiting rod, and the push rod passes through the sleeve and is slidably connected to it. By setting the limiting component, the floating plate can be fixed when the moving vehicle is pushed, preventing the floating plate from shaking.
[0015] Preferably, the outer wall of the fixed cylinder has symmetrical slide rails, and the inner wall of the slide rails is slidably connected to a slider, which is fixedly connected to the inner wall of the sleeve. By setting the slide rails and sliders, the sleeve can be guided and limited, preventing the sleeve from detaching from the fixed cylinder.
[0016] Preferably, a controller is fixedly connected to one side of the support frame, and the controller is electrically connected to both the drive motor and the electrode sensor. By setting the controller, the start and stop of the motor and the electrode sensor can be controlled.
[0017] Preferably, a push plate is fixedly connected to the end of the push rod away from the slide plate, and an anti-slip pad is fixedly connected to the surface of the push plate. The push plate can prevent the push rod from entering the limiting groove.
[0018] Preferably, both sides of the threading hole are rounded. This prevents the edges of the threading hole from cutting the thread and protects the thread. Attached Figure Description
