Description

Technical Field

[0001] This application relates to the field of geotechnical engineering technology, and more specifically, to a geotechnical engineering exploration water level measuring device. Background Technology

[0002] Geotechnical engineering is a new technical system established in civil engineering practice. It focuses on solving problems related to rock and soil masses, including foundations, slopes, and underground engineering. While civil engineering encompasses all types of engineering projects above ground, underground, and underwater, geotechnical engineering specifically refers to the portion of civil engineering involving rock, soil, underground, and water. When determining the groundwater level in rock and soil, a water level meter is required. Existing geotechnical engineering water level meters typically involve extending a cable wound around a reel for measurement. However, this method has limitations, such as when the water level meter is not used, or when the cable does not need to be wound, causing the cable to slip during reel rotation. Utility Model Content

[0003] The purpose of this application is to provide a geotechnical engineering water level measuring device to alleviate the technical problem of cable slippage caused by accidental rotation of the drum in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0005] The geotechnical engineering investigation water level measuring device provided by this utility model includes a base, a cable, a rotating mechanism, and a limiting mechanism;

[0006] The base has a through hole, and the rotating mechanism is mounted on the base;

[0007] The limiting mechanism includes a fixing frame and a limiting component. The fixing frame is installed on the base and has a through hole communicating with the through hole. One end of the cable is wound around the rotating mechanism, and the other end passes through the through hole and the through hole.

[0008] The limiting component is mounted on the side wall of the fixing frame and can move toward the center of the through hole to clamp the cable, or move away from the center of the through hole to release the cable.

[0009] Furthermore, the limiting component includes a sliding rod, and the side wall of the fixing frame is provided with a mounting hole, the axis of which is perpendicular to the axis of the through hole;

[0010] The slide bar is installed in the mounting hole and can move axially along the mounting hole.

[0011] Furthermore, a compression ball is installed at one end of the slide bar near the center of the through hole.

[0012] Furthermore, the limiting component also includes an extrusion plate, which is sleeved on the outer periphery of the fixing frame and slidably engaged with the fixing frame;

[0013] The slide bar has an inclined surface at one end away from the extrusion plate. The extrusion plate abuts against the inclined surface to drive the slide bar to move along the axial direction of the mounting hole toward the center of the through hole.

[0014] Furthermore, the limiting assembly also includes a limiting rod and a first elastic element. The limiting rod is connected to the protruding structure of the fixing frame, and its axis is parallel to and spaced apart from the axis of the through hole. The first elastic element is sleeved on the limiting rod.

[0015] One end of the first elastic element is connected to the protruding structure, and the other end is connected to the extrusion plate.

[0016] Furthermore, the inclined surface gradually slopes towards the protruding structure from the end furthest from the extrusion ball to the end closest to the extrusion ball.

[0017] Furthermore, the limiting component also includes a second elastic element, which is sleeved on the slide rod, with one end connected to the extrusion ball and the other end connected to the side wall of the mounting hole.

[0018] Furthermore, there are two mounting holes, two sliding rods, and two second elastic elements. The two mounting holes are symmetrically arranged, the two sliding rods are respectively installed in the two mounting holes, and the two second elastic elements are respectively sleeved on the two sliding rods.

[0019] Furthermore, the rotating mechanism includes a support plate, a handwheel, a rotating roller, and a take-up roller;

[0020] The support plate is installed on the base, one end of the rotating rod passes through the support plate and is connected to the handwheel, and the other end is equipped with a fixing block, and the rotating rod is rotatably connected to the support plate;

[0021] The take-up roller is sleeved on the rotating roller and is located between the support plate and the fixing block;

[0022] The cable is wound around the take-up roller.

[0023] Furthermore, the support plate and the rotating roller are rotatably connected by bearings.

[0024] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0025] The geotechnical engineering exploration water level measuring device provided by this utility model includes a base, a cable, a rotating mechanism, and a limiting mechanism; the base has a through hole, and the rotating mechanism is installed on the base; the limiting mechanism includes a fixing frame and a limiting component, the fixing frame is installed on the base and has a through hole communicating with the through hole; one end of the cable is wound around the rotating mechanism, and the other end passes through the through hole and the through hole; the limiting component is installed on the side wall of the fixing frame and can move towards the center of the through hole to clamp the cable, or move away from the center of the through hole to release the cable.

[0026] When the rotating mechanism rotates, it can reel in or unleash the cable to enable water level measurement. The limiting component can move towards the center of the through hole to clamp the cable, or move away from the center of the through hole to release the cable. This allows the cable to be clamped when the geotechnical engineering water level measurement device is not used, or when the cable does not need to be reeled in or unleashed, thus preventing the cable from slipping due to accidental rotation of the rotating mechanism.

[0038] Geotechnical engineering is a new technical system established in civil engineering practice. It focuses on solving problems related to rock and soil masses, including foundations, slopes, and underground engineering. While civil engineering encompasses all types of engineering projects above ground, underground, and underwater, geotechnical engineering specifically refers to the portion of civil engineering involving rock, soil, underground, and water. When determining the groundwater level in rock and soil, a water level meter is required. Existing geotechnical engineering water level meters typically involve extending a cable wound around a reel for measurement. However, this method has limitations, such as when the water level meter is not used, or when the cable does not need to be wound, causing the cable to slip during reel rotation.

[0039] In view of this, the geotechnical engineering exploration water level measuring device provided in this embodiment of the utility model includes a base 2, a cable 10, a rotating mechanism, and a limiting mechanism; the base 2 is provided with a through hole, and the rotating mechanism is installed on the base 2; the limiting mechanism includes a fixing frame 11 and a limiting component, the fixing frame 11 is installed on the base 2 and is provided with a through hole communicating with the through hole; one end of the cable 10 is wound around the rotating mechanism, and the other end passes through the through hole and the through hole; the limiting component is installed on the side wall of the fixing frame 11 and can move towards the center of the through hole to clamp the cable 10, or move away from the center of the through hole to release the cable 10.

[0040] When the rotating mechanism rotates, it can reel in or unleash the cable 10 to enable water level measurement. The limiting component can move towards the center of the through hole to clamp the cable 10, or move away from the center of the through hole to release the cable 10. This solves the technical problem of preventing the cable 10 from slipping due to accidental rotation of the rotating mechanism when the geotechnical engineering water level measurement device is not used or when the cable 10 does not need to be reeled in or unleashed.

[0041] The structure of base 2 is described in detail below:

[0042] In the optional solution provided in this embodiment of the utility model, the base 2 is fixedly connected to the caster wheel 3.

[0043] Specifically, four casters 3 are fixedly connected to the bottom of the base 2. Of course, the number of casters 3 can vary, such as having two, and should also be within the protection scope of this utility model embodiment.

[0044] The base 2 is equipped with casters 3 for easy movement.

[0045] The structure of the rotating mechanism is described in detail below:

[0046] In the optional embodiment of this utility model, the rotating mechanism includes a support plate 5, a handwheel 4, a rotating roller 6, and a take-up roller 8; the support plate 5 is installed on the base 2, one end of the rotating roller 6 passes through the support plate 5 and is connected to the handwheel 4, and the other end is installed with a fixing block 7, and the rotating roller 6 is rotatably connected to the support plate 5; the take-up roller 8 is sleeved on the rotating roller 6 and is located between the support plate 5 and the fixing block 7; the cable 10 is wound around the take-up roller 8.

[0047] Specifically, the support plate 5 is connected to the upper surface of the base 2, and the support plate 5 is perpendicular to the base 2. Furthermore, the support plate 5 is fixedly connected to the base 2, for example, by welding or bonding. A handwheel 4 is provided on one side of the support plate 5, a rotating roller 6 is fixedly connected to the outer surface of the handwheel 4, a positioning block 61 is fixedly connected to the outer surface of the rotating roller 6, a take-up roller 8 is sleeved on the outer surface of the rotating roller 6, a fixing block 7 is sleeved at one end of the rotating roller 6, and a cable 10 is provided on the outer surface of the take-up roller 8.

[0048] The base 2 provides a good installation environment for other components, ensuring the normal operation of the measurement work. The casters 3 facilitate the movement of the measurement device by the staff. The support plate 5 supports the rotating roller 6. The handwheel 4 drives the rotating roller 6 to rotate. Since the positioning block 61 is engaged with the winding roller 8, the winding roller 8 rotates at the same time as the rotating roller 6, thereby realizing the unloading and winding of the cable 10. The fixing block 7 is threadedly connected to the rotating roller 6 to limit the winding roller 8 and ensure that the winding roller 8 will not be displaced.

[0049] In the optional embodiment of this utility model, the support plate 5 and the rotating roller 6 are rotatably connected by a bearing 9.

[0050] Specifically, a bearing 9 is fixedly connected to the outer surface of the rotating roller 6.

[0051] The handwheel 4 drives the rotating roller 6 to rotate inside the bearing 9, thus enabling the roller 6 to rotate. The rotation of the roller 6 by the handwheel 4 drives the take-up roller 8 to rotate. The rotation of the take-up roller 8 enables the take-up or unwinding of the cable 10, ensuring the normal operation of the measurement work. The support plate 5 provides a fixed position for the roller 6, and the fixing block 7 is threadedly connected to the roller 6 to ensure that the take-up roller 8 will not fall off. The positioning block 61 ensures that the roller 6 can normally drive the take-up roller 8 to rotate.

[0052] The following is a detailed description of the structure of the limit mechanism:

[0053] In the optional solution provided by this utility model embodiment, the limiting component includes a slide rod 15, and the side wall of the fixing frame 11 is provided with a mounting hole, the axis of the mounting hole being perpendicular to the axis of the through hole; the slide rod 15 is installed in the mounting hole and can move along the axial direction of the mounting hole.

[0054] Specifically, in this embodiment, the axis of the mounting hole is perpendicular to the axis of the through hole.

[0055] The slide bar 15 is installed in the mounting hole and can move along the axial direction of the mounting hole. When the slide bar 15 extends into the through hole, it can clamp the cable 10. When the slide bar 15 extends out of the through hole, it can release the cable 10.

[0056] In the optional embodiment of this utility model, a compression ball 18 is installed at one end of the slide bar 15 near the center of the through hole.

[0057] Specifically, the surface of the extruded ball 18 is spherical.

[0058] The compression ball 18 increases the contact area between the slide bar 15 and the cable 10, thereby enhancing the clamping force.

[0059] In the optional solution provided by this utility model embodiment, the limiting component further includes a pressing plate 14, which is sleeved on the outer periphery of the fixing frame 11 and slides in cooperation with the fixing frame 11; the end of the slide rod 15 away from the pressing plate 14 is provided with an inclined surface 16, and the pressing plate 14 abuts against the inclined surface 16 to drive the slide rod 15 to move along the axial direction of the mounting hole toward the center of the through hole.

[0060] Specifically, the extrusion plate 14 is slidably engaged with the fixing frame 11 and can move along the axial direction of the through hole; when the extrusion plate 14 moves along the axial direction of the through hole and contacts the inclined surface 16, the inclined surface 16 slowly drives the slide rod 15 to move inward.

[0061] The pressing plate 14 is used to drive the slide bar 15 to move in the direction of extending into the through hole, so that the slide bar 15 can clamp the cable 10.

[0062] In the optional solution provided by this utility model embodiment, the limiting component further includes a limiting rod 12 and a first elastic member 13. The limiting rod 12 is connected to the protruding structure of the fixing frame 11, and its axis is parallel to and spaced apart from the axis of the through hole. The first elastic member 13 is sleeved on the limiting rod 12. One end of the first elastic member 13 is connected to the protruding structure, and the other end is connected to the extrusion plate 14.

[0063] Specifically, the first elastic element 13 is configured as a spring, and the first elastic element 13 is located above the extrusion plate 14. Furthermore, the inclined surface 16 gradually slopes towards the protruding structure from the end away from the extrusion ball 18 to the end closer to the extrusion ball 18.

[0064] The outer surface of the base 2 is provided with a fixing frame 11. A limiting rod 12 is fixedly connected to the outer surface of the fixing frame 11. A first elastic element 13 is sleeved on the outer surface of the limiting rod 12. A pressing plate 14 is fixedly connected to one end of the first elastic element 13. A sliding rod 15 is sleeved on the inner wall of the fixing frame 11. An inclined surface 16 is provided on the outer surface of the sliding rod 15. A pressing ball 18 is fixedly connected to one end of the sliding rod 15. The fixing frame 11 clamps and fixes the cable 10 to ensure that the cable 10 will not slip during measurement. The limiting rod 12 ensures that the first elastic element 13 will not be twisted or deformed. The first elastic element 13 drives the pressing plate 14 to slide along the limiting rod 12, thereby pressing the inclined surface 16, which in turn drives the sliding rod 15 to move. The movement of the sliding rod 15 drives the pressing ball 18 to move, thereby clamping and fixing the cable 10.

[0065] In the optional solution provided by this utility model embodiment, the limiting component further includes a second elastic member 17, which is sleeved on the slide rod 15, with one end connected to the extrusion ball 18 and the other end connected to the side wall of the mounting hole.

[0066] Specifically, the second elastic element 17 is configured as a spring, and the mounting hole is configured as a stepped hole, with the second elastic element 17 abutting against the stepped position.

[0067] While the compression ball 18 moves, the second elastic element 17 is stretched to ensure that the second elastic element 17 can drive the slide bar 15 to reset normally, thereby releasing the clamping of the cable 10.

[0068] In the optional solution provided by the embodiment of this utility model, there are two mounting holes, two slide rods 15 and two elastic elements 17. The two mounting holes are symmetrically arranged, the two slide rods 15 are respectively installed in the two mounting holes, and the two elastic elements 17 are respectively sleeved on the two slide rods 15.

[0069] Specifically, the number of mounting holes, slide rod 15, and second elastic element 17 remains the same.

[0070] The two slide bars 15 are symmetrically arranged so that the two slide bars 15 work together to clamp the cable 10, thereby improving the clamping effect on the cable 10.

[0071] The working principle of the water level measuring device for geotechnical engineering investigation is explained in detail below:

[0072] See Figures 1 to 5 As shown, when the staff uses the measuring device to perform the measurement work, the staff first moves the base 2 by using the universal wheel 3, and then drives the rotating roller 6 to rotate inside the bearing 9 by turning the handwheel 4. Since the positioning block 61 is engaged with the take-up roller 8, the take-up roller 8 is driven to rotate at the same time as the rotating roller 6 rotates, thereby realizing the work of unloading and rewinding the cable 10. By setting the fixing block 7 to be threadedly connected to the rotating roller 6, the take-up roller 8 is limited to ensure that the take-up roller 8 will not be displaced.

[0073] The sliding rod 15 clamps the cable 10 after the cable is unloaded, preventing it from stretching due to water flow. The first elastic element 13 moves the compression plate 14, which in turn compresses the inclined surface 16 of the sliding rod 15, causing it to move inward. Simultaneously, the sliding rod 15 stretches the second elastic element 17, thus clamping and securing the cable 10. To release the clamp, the compression plate 14 is slid upwards, compressing the first elastic element 13. This movement of the compression plate 14 releases the restriction on the sliding rod 15. The rebound of the second elastic element 17 then resets the sliding rod 15, releasing the clamp on the cable 10. In other words, when the cable 10 is laid out, the squeezing plate 14 is lifted manually to release the squeezing pressure of the squeezing plate 14 on the slide bar 15, and the squeezing plate 14 squeezes the first elastic element 13 to deform; after the cable 10 is laid out, the squeezing plate 14 is released manually, the first elastic element 13 returns to its original shape and drives the squeezing plate 14 downward, and the squeezing plate 14 squeezes the slide bar 15 to move inward to clamp the cable 10.

[0074] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
