[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0033] Example 1:

[0034] like Figures 1 to 6 As shown, a geotechnical engineering investigation water level measuring device includes a workbench 101 and a hydraulic cylinder 201 mounted on the workbench 101. The workbench 101 includes an upper water level prediction unit 300 and a lower water level prediction unit 400. The hydraulic cylinder 201 is connected to the upper water level prediction unit 300 and the lower water level prediction unit 400. When detecting the water level, the hydraulic cylinder 201 drives the upper water level prediction unit 300 and the lower water level prediction unit 400 to move downwards synchronously. The upper water level prediction unit 300 detects and warns of excessively high water level, and the lower water level prediction unit 400 detects and warns of excessively low water level. If the upper water level prediction unit 300 issues an alarm first, it indicates that the water level is high; if the lower water level prediction unit 400 issues an alarm first, it indicates that the water level is low.

[0035] When this solution is in use, the water level is detected by the synchronously descending upper water level prediction unit 300 and lower water level prediction unit 400. If the upper water level prediction unit 300 contacts the water surface first during the descent, an alarm is triggered. If the upper water level prediction unit 300 does not contact the water surface after descending a certain distance, the lower water level prediction unit 400 triggers an alarm.

[0036] This scheme provides a completely new method for measuring or determining whether the water level is high or low in geotechnical engineering investigations.

[0037] like Figure 5 and Figure 6 As shown, the output end of the hydraulic cylinder 201 is connected to a circular fixed plate 2011; the upper water level prediction unit 300 includes a first mounting column 2012, one end of which is fixed to the circular fixed plate 2011, and the other end away from the circular fixed plate 2011 is connected to a circular limiting plate 2013 and a first float 2014. A circular mounting cylinder 202 is movably connected between the first float 2014 and the circular limiting plate 2013. A movable rod is provided inside the circular mounting cylinder 202, one end of which is fixed to the circular limiting plate 2013, and the other end is movably disposed inside the circular mounting cylinder 202; a displacement measuring device 203 is also provided on the first float 2014.

[0038] In the process of lowering, the circular mounting cylinder 202 and the movable rod are provided with a limiting structure to avoid the first floating plate 2014 from directly falling under the action of gravity. When the first floating plate 2014 contacts the water surface, the first floating plate 2014 floats on the water surface under the action of buoyancy, and continues to descend. The circular limiting plate 2013 drives the movable rod to enter the inside of the circular mounting cylinder 202 for distance contraction. After moving to a certain distance, the movement stops. The displacement measurer 203 detects the distance and transmits the data to the ground end. The controller of the ground end receives the signal to make the voice alarm alarm.

[0039] In the process of water fluctuation, the wave will go down. At this time, the first floating plate 2014 suspended will follow the wave downward, indicating that the water level is detected at a high position.

[0040] When the wave will go up, the wave pushes the first floating plate 2014 to follow up, indicating that the water level is detected at a low position.

[0041] As shown in Figure 4 and Figure 5 , the lower water level prediction unit 400 includes a second mounting column 2016, one end of which is fixed on the circular fixed plate 2011, and the other end away from the circular fixed plate 2011 is movably connected with a second floating plate 2017; the second floating plate 2017 is fixedly installed with a placing floating plate 401, which is slidably arranged on the second mounting column 2016. The placing floating plate 401 is fixedly connected with an L-shaped positioning plate 4011 at one end. The second floating plate 2017 is movably installed with a swing arm 402 at one end. The swing arm 402 is movably connected with a second turnover plate 4021 at the other end. The second turnover plate 4021 is fixedly installed with a rotating rod, and the rotating rod is provided with bearings at both ends. The lower water level prediction unit 400 includes a special-shaped block 4013 installed on the inner wall of the workbench 101. The special-shaped block 4013 is provided with a fourth sliding rail 4014, and the fourth sliding rail 4014 is fixedly installed with a telescopic lock rod 4012. The telescopic lock rod 4012 is slidably provided with an L-shaped positioning plate 4011, and one end of the telescopic lock rod 4012 is inserted into the second mounting column 2016.

[0042] If it continues to go down, neither the first floating plate 2014 nor the second floating plate 2017 contacts the water surface, indicating that the overall water level is too low.

[0043] As shown in Figure 1 , the workbench 101 is fixedly installed with support legs 1011 around the top. Four support legs 1011 are installed with a top plate 1012 above. A rectangular notch 1014 is formed in the workbench 101. Two cavities are arranged in the workbench 101. A placing plate 1013 is arranged above the workbench 101.

[0044] The implementation principle of a geotechnical engineering investigation water level measuring device according to the embodiment is as follows:

[0045] Firstly, the workbench 101 is placed at the geotechnical engineering water level that needs to be investigated, when the placement is completed, the staff controls the hydraulic cylinder 201 or other lifting mechanism to operate, when the hydraulic cylinder 201 operates, the circular fixed plate 2011 can be driven to move vertically downward, when the circular fixed plate 2011 moves vertically downward, the first mounting column 2012 and the second mounting column 2016 can be driven to move vertically downward, when the first mounting column 2012 and the second mounting column 2016 move vertically downward, the first floating plate 2014 and the second floating plate 2017 can be driven to move vertically downward;

[0046] If the first floating plate 2014 contacts the water surface, at this time, the first floating plate 2014 is suspended on the water surface under the action of the buoyancy, continues to move downward by a distance, keeps stable, the displacement measuring device 203 detects the distance change to generate a signal to alarm, at this time, it is indicated that the overall water level is at a high position;

[0047] At this time, if the water surface is fluctuant and has a large fluctuation, the suspended first floating plate 2014 will move up and down on the first mounting column 2012 following the fluctuation of the wave, and the displacement measuring device 203 is used to detect and record the displacement distance;

[0048] During the descending process, if it is not contacted with the water surface all the time, the lower water level prediction unit 400 will move to a certain distance and then mechanical alarm occurs;

[0049] If the water surface is gentle or in the water level rising period, during the descending process, the distance between the first floating plate 2014 and the circular limiting plate 2013 will only continuously decrease, generally, there is no elongation or invariable condition;

[0050] If the elongation or invariable condition occurs, it is indicated that the water level is at a high position at this time;

[0051] Because the second mounting column 2016 is provided with the second floating plate 2017 and the placement floating plate 401 vertically downwardly moves because the placement floating plate 401 is fixedly installed with the L-shaped positioning plate 4011, and the L-shaped positioning plate 4011 is slidably provided with the telescopic locking rod 4012 which is inserted on the second mounting column 2016, so that the second floating plate 2017 and the placement floating plate 401 can vertically downwardly move, and when the second floating plate 2017 and the placement floating plate 401 move to a certain position, the telescopic locking rod 4012 can be slid to the fourth sliding rail 4014 provided on the special-shaped block 4013, so that the telescopic locking rod 4012 can be ensured to be away from the second floating plate 2017, thereby achieving unlocking, and when the water level is located below the placement floating plate 401 after unlocking, the placement floating plate 401 can be knocked in the inner cavity of the workbench 101 by the second turnover plate 4021 under the gravity of the second turnover plate 4021 through the swing arm 402, thereby generating an alarm and warning that the water level is too low.

[0052] If there is no water below, the second floating plate 2017 will descend and knock, and if there is water below, the second floating plate 2017 will be held by the buoyancy of the water surface, avoiding the second floating plate 2017 from descending and knocking.

[0053] Therefore, when knocking occurs, it means that the water level is at a low position, i.e., the water level is lowered to knock, and the water level is raised to hold the second floating plate 2017 and cannot knock.

[0054] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0055] Although the embodiments of the present application have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application.
