Technical Field

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

[0002] When using a water level measuring device for survey and construction, first drill a hole in the proposed site to reach the level where the groundwater is located. In order to be able to measure the height of the groundwater level, the probe part of the water level measuring device is placed in the drill hole, and the water level measuring probe is lowered to a position where it contacts the groundwater.

[0003] In survey and construction projects, accurate measurement of water levels is crucial, which not only affects the design and planning of the project, but also plays a decisive role in ensuring the safety and efficiency of the construction process. Changes in water levels can reflect the influence of many natural and human factors, including rainfall, groundwater flow, and changes in the surrounding environment. Therefore, the development of reliable water level measurement devices has become an important task in the field of engineering technology.

[0004] For example, Chinese patent 202221850622.X discloses a water level measuring device for geotechnical investigation and construction, which includes a winding roller, a cable is wound around the surface of the winding roller, a protective cover is fixedly connected to the bottom of the cable, and a measuring probe extending to the outside of the protective cover is movably connected inside the protective cover to protect the measuring probe. However, the above device still has the following shortcomings: no reference point is set before the measuring probe is lowered, and the starting position of the measuring probe needs to be manually adjusted before each water level measurement, which not only increases the complexity and time required for the operation, but also increases the possibility of human error during the measurement process.

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

[0006] In view of the problems in the related technology, the utility model proposes a water level measuring device for survey and construction to overcome the above technical problems existing in the existing related technology.

[0007] To this end, the specific technical solutions adopted by the utility model are as follows:

[0008] A water level measuring device for survey and construction comprises a bracket, a mounting frame is arranged on the top of the bracket, a winding roller is arranged in the middle of the mounting frame, a cable with a scale is sleeved on the outer side of the winding roller, and a crank is arranged at one end of the winding roller; a reference plate fixing mechanism is arranged at one end of the bottom of the mounting frame, the cable with a scale is inserted in the reference plate fixing mechanism, and a protective component is arranged at the bottom end of the cable with a scale, and a water level measuring probe is arranged in the protective component.

[0024] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] According to an embodiment of the utility model, a water level measuring device for use in survey and construction is provided.

[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-5 As shown, according to the embodiment of the utility model, the water level measuring device for investigation and construction includes a bracket 1, a mounting frame 2 is arranged on the top of the bracket 1, a winding roller 3 is arranged in the middle of the mounting frame 2, a cable 4 with a scale is sleeved on the outer side of the winding roller 3, a crank 5 is arranged at one end of the winding roller 3, and a handle is arranged at the top of the mounting frame 2. When in use, the staff can drive the device to move by grasping the handle, and the crank 5 at one end of the winding roller 3 can be replaced by a driving mechanism such as a motor to realize automatic lifting of the cable 4 with a scale; a reference plate fixing mechanism 6 is arranged at one end of the bottom of the mounting frame 2, the cable 4 with a scale is inserted in the reference plate fixing mechanism 6, and a protective component 7 is arranged at the bottom end of the cable 4 with a scale, and a water level measuring probe 8 is arranged in the protective component 7.

[0027] In addition, the water level measuring device for survey and construction is placed at the predetermined survey and construction site. The bracket 1 provides a stable foundation. Through the reference plate fixing mechanism 6, the user can quickly adjust the scaled cable 4 to a predetermined starting position. The operator turns the crank 5 to make the winding roller 3 release or retract the scaled cable 4 until the water level measuring probe 8 reaches the required water level measurement point. By observing the scale on the cable, the water level height can be directly read.

[0028] Among them, the water level measuring probe 8 is a conductivity sensor that uses the conductivity of water to detect the water level. When part of the water level measuring probe 8 is immersed in water, the conductive property of water allows current to flow from one part of the water level measuring probe 8 to another part. That is, due to the conductivity of water, the current can be conducted through water, so that the water level measuring probe 8 can detect the change of water level. The water level measuring probe 8 detects the amount of current flowing through, and determines whether the liquid surface position is reached based on the change of current. When the water level measuring probe 8 detects that the water level change (i.e., the change of current) reaches a predetermined condition, an electronic signal is generated. This signal is transmitted to the control unit wirelessly, triggering a visual or audible alarm, such as the lighting of an LED light or the sound of a buzzer, prompting the operator to stop lowering the scale cable 4.

[0029] With the aid of the above solution, the utility model can adjust the starting position of the scaled cable 4 to a fixed point before measuring the water level, thereby reducing the error caused by human operation and improving the accuracy and repeatability of the measurement.

[0030] In one embodiment, for the above-mentioned reference plate fixing mechanism 6, the reference plate fixing mechanism 6 includes a fixing block 601 arranged at one end of the bottom of the mounting frame 2, the fixing block 601 is connected to the mounting frame 2 through a connecting plate 602, a reference plate 603 is arranged at one end of the fixing block 601 close to the scaled cable 4, a circular hole 604 is arranged in the vertical direction in the reference plate 603, and the scaled cable 4 is inserted in the circular hole 604; a clamping block 605 is slidably arranged at one end of the circular hole 604 close to the fixing block 601, and the clamping block 605 is close to one end of the fixing block 601. A receiving hole 606 is provided in the reference plate 603, a baffle 607 is provided at one end of the clamping block 605 located at the receiving hole 606, a spring 608 is provided between the baffle 607 and the inner wall of the receiving hole 606, and the spring 608 is a compression spring; a bolt 609 is connected to the inner thread of the fixing block 601, and one end of the bolt 609 extends to the side wall of the baffle 607, so that the scaled cable 4 can be adjusted to a predetermined starting position before each measurement, which not only reduces the need to manually set the reference point, but also improves the repeatability and accuracy of the measurement. Through the coordinated use of the clamping block 605, the spring 608 and the bolt 609, the scaled cable 4 can be clamped when the water level measuring probe 8 is recovered and not in use, so that the scaled cable 4 can be prevented from shaking, thereby avoiding the protective component 7 and the water level measuring probe 8 from shaking significantly, which is conducive to preventing the protective component 7 from colliding with other objects.

[0031] The working principle of the reference plate fixing mechanism 6 is as follows: the fixing block 601 is combined with the mounting frame 2 through the connecting plate 602, providing a stable foundation for the structure. The scaled cable 4 passes through the circular hole 604 in the reference plate 603. Before measuring the water level, the top of the protective component 7 is brought into contact with the bottom of the reference plate 603 to determine the starting position. If it is necessary to clamp the scaled cable 4, the scaled cable 4 is clamped by rotating the bolt 609 and pushing the baffle 607, the clamping block 605, etc. forward, and the clamping block 605 squeezes the scaled cable 4, and the force of the spring 608 makes the bolt 609 not easy to loosen. After the bolt 609 rotates in the opposite direction, under the action of the spring 608, the clamping block 605 leaves the scaled cable 4, thereby loosening the scaled cable 4.

[0032] In one embodiment, for the above-mentioned protective component 7, the protective component 7 includes a protective shell 701 arranged on the outside of the water level measuring probe 8, and a positioning plate 702 is arranged at the top of the protective shell 701 and at the bottom end of the scaled cable 4; a protective plate 703 is arranged at the bottom end of the protective shell 701, and the protective plate 703 is arranged as a hollow structure, thereby providing solid protection for the water level measuring probe 8, reducing damage caused by external impact or other physical factors, and extending the service life of the water level measuring probe 8. The hollow design of the protective plate 703 ensures that water and other measuring media can flow freely around the water level measuring probe 8; the positioning plate 702 is in contact with the reference plate 603, so that the starting position is determined before each water level measurement.

[0033] The working principle of the protection assembly 7 is as follows: the protection shell 701 protects the water level measuring probe 8 from external physical impact. The positioning plate 702 enables the starting position of the water level measuring probe 8 to be quickly determined before each water level measurement.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] In actual application, the operator controls the winding roller 3 through the crank 5 to release or retract the scaled cable 4, and the bottom end of the scaled cable 4 carries the water level measuring probe 8 to the required measuring point. Before each measurement, the reference plate fixing mechanism 6 automatically adjusts the scaled cable 4, the water level measuring probe 8, etc. to the preset starting position to ensure the consistency and accuracy of the measurement. The water level measuring probe 8 performs water level measurement under the protection of the protective component 7. Through the scaled cable 4, the operator can directly read the water level data.

[0036] In summary, the utility model can adjust the starting position of the scaled cable 4 to a fixed point before measuring the water level, reducing the error caused by human operation and improving the accuracy and repeatability of the measurement. By setting the reference plate fixing mechanism 6, the scaled cable 4 can be adjusted to a predetermined starting position before each measurement, which not only reduces the need to manually set the reference point, but also improves the repeatability and accuracy of the measurement. When the water level measuring probe 8 is recovered and not in use, the scaled cable 4 can be clamped, which can prevent the scaled cable 4 from shaking, thereby avoiding the protective component 7 and the water level measuring probe 8 from shaking significantly, which is conducive to preventing the protective component 7 from colliding with other objects. By setting the protective component 7, a solid protection is provided for the water level measuring probe 8, reducing the damage caused by external impact or other physical factors, and extending the service life of the water level measuring probe 8. The hollow design of the protective plate 703 ensures that water and other measuring media can flow freely around the water level measuring probe 8; the positioning plate 702 contacts the reference plate 603, so that the starting position is determined before each water level measurement.
