During the implementation of geotechnical exploration operations, it is often necessary to measure the water level depth in the explored area.

[0003] Depth gauges are commonly used to measure water levels. Their working principle is primarily based on the propagation characteristics of sound waves in water. When testing target waters, personnel must maneuver the vessel to relocate the depth gauge to achieve full coverage of the target waters. However, geotechnical exploration waters are complex, making it difficult for personnel to maneuver the vessel. Furthermore, launching the vessel presents significant risks, making it difficult to conduct comprehensive exploration operations using a depth gauge. The complex environment of the target waters also affects the accuracy of the depth gauge's water level measurements, leading to unsatisfactory exploration results. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example: Reference Figure 1-6The device for measuring water levels for geotechnical exploration shown in FIG. 1 includes a first float 1, a measuring tube 2, and a hook rod 3. A hook 4 is fixed to one end of the hook rod 3. A fixing block 5 is fixed to the middle of the first float 1. A chute 6 is defined in the middle of the fixing block 5, through which the measuring tube 2 passes. A rubber balloon 7 is fixedly connected to the bottom end of the measuring tube 2. A carrying rod 8 is fixed to the bottom of the rubber balloon 7. A counterweight assembly is provided at the bottom of the carrying rod 8 for pulling the measuring tube 2 downward in the water. A charging and discharging assembly is provided at the top end of the measuring tube 2 for inflating and deflating the rubber balloon 7. Multiple reinforcement assemblies are provided on the fixing block 5 for enhancing the stability of the first float 1 in the water.

[0025] The hook rod 3 can be used to move the first float 1, so that the measuring tube 2 inserted in the middle of the first float 1 can move with the first float 1 and change its position. As the water level increases, the measuring tube 2 can be pulled downward by the counterweight assembly. The change in the water level of the target water area can be obtained by referring to the scale provided on the measuring tube 2 and recorded accordingly. If the measuring tube 2 encounters an underwater obstacle and cannot move, the rubber balloon 7 can be inflated by the charging and discharging assembly. When the rubber balloon 7 expands, it drives the measuring tube 2 to float upward, thus facilitating the continued transfer of the measuring tube 2 and the removal of the device from the water.

[0026] Among them, a plurality of reserved grooves 9 are opened at the edge of the slide 6, and the plurality of reserved grooves 9 are distributed in a circular array, and a group of auxiliary wheels 10 are rotatably connected between the relative inner walls of the reserved grooves 9 through bearings. The measuring tube 2 is slidably inserted into the slide 6 opened on the fixed block 5. A plurality of reserved grooves 9 are opened at the edge of the slide 6, and a group of auxiliary wheels 10 are arranged inside the reserved grooves 9. With the support of multiple groups of auxiliary wheels 10, the measuring tube 2 will move up and down inside the slide 6 more smoothly.

[0027] The counterweight assembly includes a counterweight cone 11, a counterweight plate 12 is fixed to the bottom of the counterweight cone 11, a stud 13 is fixed to the top of the counterweight cone 11, and the stud 13 is threadedly connected to the carrier rod 8;

[0028] The stud 13 is fixed to the bottom end of the carrier rod 8 by means of a threaded connection, so that the counterweight assembly can be assembled and disassembled as needed, thereby facilitating the use and transportation of the device.

[0029] Among them, the charging and discharging assembly includes an air pump 14, the air outlet of the air pump 14 is fixedly connected to an air supply pipe 15, the air supply pipe 15 is fixedly connected to an exhaust pipe 16, the exhaust pipe 16 is provided with an exhaust valve, the outside of the air supply pipe 15 is fixedly sleeved with a sealing plate 17, the sealing plate 17 is fixedly installed on the top of the measuring tube 2, the air supply pipe 15 is connected to the measuring tube 2, the air inlet of the air pump 14 is fixedly connected to an air intake pipe 18, and the other end of the air intake pipe 18 is provided with a filter 19;

[0030] The air pump 14 is used to send the air filtered by the filter 19 into the measuring tube 2 along the air supply pipe 15, so that the air is transported along the measuring tube 2 to the inside of the rubber balloon 7, helping the rubber balloon 7 to expand and bulge, so that the internal air pressure of the rubber balloon 7 increases, the buoyancy increases, and the measuring tube 2 can be pulled upward. The exhaust valve on the exhaust pipe 16 is opened to discharge the air in the rubber balloon 7, so that the rubber balloon 7 can complete the inflation and deflation operations as needed.

[0031] The reinforcement assembly includes a fixing rod 20, one end of which is fixed with a connecting plate 21, on which two bolts 22 are provided, and the two bolts 22 are used to fix the connecting plate 21 to the fixing block 5. The other end of the fixing rod 20 is fixed with a carrier block 24, on which a second floating ring 23 is fixed. A fixing ring 25 for the hook 4 to be hooked is fixed to the fixing rod 20;

[0032] The counterweight cone 11 is fixed to the fixed block 5 by two bolts 22, so that the first float ring 1 is connected to the second float ring 23. The second float ring 23 can improve the stability of the first float ring 1 on the water surface, making the measurement tube 2 more stable when moving its position and measuring the water level.

[0033] Working principle of this utility model:

[0034] During transportation, the first float 1, rubber balloon 7, and second float 23 are all deflated. At this point, they are relatively small, making them easier to transport and move. Upon reaching the target waters, air is pumped into the first and second floats 1, 23. The bolts 22 are tightened with a wrench to secure the connecting plate 21 to the fixing block 5. This completes the connection between the first and second floats 1, 23. The measuring tube 2 is inserted into the chute 6 and tightly fitted with the plurality of auxiliary wheels 10. The counterweight assembly is removed, and the stud 13 is screwed into the bottom end of the carrier rod 8, securing the counterweight assembly to the bottom end of the carrier rod 8 via a threaded connection. The first and second floats 1, 23 are then pushed into the target waters, allowing them to float on the water. The hook rod 3 is removed, and the hook 4 is hooked onto any of the fixing rings 25. The first float 1 is then moved, causing it to pull the measuring tube 2 from shallow water to deep water.

[0035] As the measuring tube 2 moves toward the deep water area, it continuously moves downward. By referring to the scale provided on the measuring tube 2, the water level change can be determined and recorded accordingly. If the movement of the measuring tube 2 is blocked and attempts to move it further fail, the air pump 14 can be activated to inflate the measuring tube 2, causing the rubber balloon 7 to expand. As the rubber balloon 7 continues to grow in size, its buoyancy increases, which can drive the counterweight assembly upward. Subsequently, the position of the first float 1 is moved by means of the hook rod 3, and the exhaust valve on the exhaust pipe 16 is opened to exhaust the air in the rubber balloon 7, reducing its buoyancy. The counterweight assembly drives the measuring tube 2 downward again. After repeatedly adjusting the position of the first float 1, the approximate water level of the exploration area can be determined. After recording, the device can be removed from the target waters.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
