Description

Technical Field

[0001] This utility model relates to the field of pore water pressure monitoring technology, specifically a pore water pressure monitoring device. Background Technology

[0002] Pore ​​water pressure monitoring is a key safety monitoring technology in geotechnical engineering and hydraulic engineering. It is mainly used to measure changes in pore water pressure inside soil, rock, or concrete structures. Pore water pressure monitoring often uses vibrating wire manometers, which are instruments that sense pressure by measuring changes in the vibration frequency of a metal wire. Due to their excellent long-term stability and anti-interference capabilities, they play a vital role in civil engineering, geological monitoring, and other fields.

[0003] The published patent document CN221280530U discloses an easy-to-operate steel wire pore water pressure gauge. This patent document utilizes a coordinated design between a first sliding rod, a damping spring, and an arc-shaped anti-collision plate. During use, when the pressure gauge body collides with something, the arc-shaped anti-collision plate is subjected to pressure, causing the damping spring to contract, sliding the first sliding rod into the first sliding tube. The damping spring then rebounds, reducing the impact force on the pressure gauge body and improving stability. This minimizes the risk of the steel wire pore water pressure gauge colliding with the borehole sidewall, which could lead to malfunctions and inaccurate testing. However, the aforementioned patent document does not allow for adjustment and control of the winding position when winding the cable, resulting in uneven winding and potential cable tangling, which could affect subsequent use.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-3 This utility model provides a pore water pressure monitoring device, including a U-shaped frame 1 and a vibrating wire pressure gauge 2. A wire roller 3 is rotatably mounted inside the U-shaped frame 1, and a vertical hole 5 is provided on one side of the U-shaped frame 1. A cable 4 is mounted on the wire roller 3, and one end of the cable 4 is connected to the vibrating wire pressure gauge 2. A slider 12 and a reciprocating screw 18 are slidably connected and rotatably mounted inside the vertical hole 5. The reciprocating screw 18 passes through the slider 12, and the slider 12 is threadedly connected to the reciprocating screw 18. A wire hole 19 is provided on the slider 12. Cable 4 passes through wire hole 19. Rotary shaft 6, rotating shaft 7 and rotating shaft 8 are rotatably installed on the top of U-shaped frame 1. The lower end of rotating shaft 6 is fixedly installed with the top of wire roller 3, and gear 9 is sleeved and fixedly installed on rotating shaft 6. Gear 10 is sleeved and fixedly installed on rotating shaft 7. The lower end of rotating shaft 8 is fixedly installed with the upper end of reciprocating screw 18, and gear 11 is sleeved and fixedly installed on rotating shaft 8. Gear 10 meshes with gear 9 and gear 11.

[0023] In this technical solution, rotating the first shaft 6 drives the wire roller 3 to rotate, thereby winding the cable 4. At the same time, the first shaft 6 drives the third shaft 8 to rotate through the first gear 9, the second gear 10, the second shaft 7, and the third gear 11. The third shaft 8 drives the reciprocating screw 18 to rotate, and the reciprocating screw 18 drives the slider 12 to move vertically back and forth along the vertical hole 5, so that the position of the wire hole 19 moves vertically back and forth. Thus, while winding the cable 4, the winding position is controlled, and the neatness of the cable 4 after winding is increased.

[0024] In some technical solutions, such as Figure 1 , Figure 4 and Figure 5 As shown, a cleaning fluid cylinder 13 matching the vibrating wire pressure gauge 2 is provided on the front side of the U-shaped frame 1. The U-shaped frame 1 is filled with cleaning fluid. A vertical ring 24 is provided inside the cleaning fluid cylinder 13. Four positioning rods 26 are fixedly connected to the inner wall of the cleaning fluid cylinder 13. An annular sponge 25 is fixedly connected to the inner wall of the vertical ring 24. Four positioning holes 27 matching the positioning rods 26 are opened on the outer wall of the vertical ring 24. The positioning rods 26 are located inside the positioning holes 27.

[0025] In use, the vertical ring 24 is placed inside the cleaning fluid cylinder 13, allowing each positioning rod 26 to enter the corresponding positioning hole 27. Then, the unused vibrating wire pressure gauge 2 is inserted into the vertical ring 24. The vibrating wire pressure gauge 2 comes into contact with and rubs against the annular sponge 25, which serves both as a temporary storage and placement of the vibrating wire pressure gauge 2 and as a way to clean the surface of the idle vibrating wire pressure gauge 2, thus not affecting the next use of the vibrating wire pressure gauge 2.

[0026] In some technical solutions, such as Figure 3 As shown, several ball bearings 20 are rotatably mounted on the inner wall of the wire hole 19.

[0027] During use, multiple ball bearings 20 prevent the cable 4 from contacting and abrading the inner wall of the wire hole 19, thus protecting the cable 4.

[0028] In some technical solutions, such as Figure 1-2 As shown, a turntable 14 is fixedly installed on the upper end of the rotating shaft 6, and a handle 15 is rotatably installed on one side of the top of the turntable 14.

[0029] When in use, the rotating shaft 6 can be easily rotated by the handle 15 on one side of the top of the turntable 14.

[0030] In some technical solutions, such as Figure 4 As shown, two mounting rings 23 are fitted and fixedly connected to the cleaning liquid cylinder 13, and a drain pipe 21 is connected to the bottom of the cleaning liquid cylinder 13. The rear side of the mounting rings 23 is fixedly installed to the front side of the U-shaped frame 1, and a gate valve 22 is provided on the drain pipe 21.

[0031] In use, the gate valve 22 facilitates the drain pipe 21, thereby making it easy to discharge the cleaning fluid in the cleaning fluid cylinder 13.

[0032] In some technical solutions, such as Figure 1-2 As shown, a base frame 16 is fixedly connected to the bottom of the U-shaped frame 1, and support legs 17 are fixedly installed at the four corners of the bottom of the base frame 16.

[0033] When in use, the stability of the device is increased by the support feet 17 at the four corners of the bottom of the base frame 16.

[0034] Working principle: During use, rotating the first shaft 6 by using the handle 15 on the turntable 14 will drive the wire roller 3 to rotate, thereby winding or unwinding the cable 4, thus adjusting the height of the vibrating wire pressure gauge 2 to be suitable for monitoring pore water pressure at different depths. When winding the cable 4, the first shaft 6 drives the third shaft 8 to rotate through gears 9, 10, 7, and 11. The third shaft 8 drives the reciprocating screw 18 to rotate, and the reciprocating screw 18 drives the slider 12 to reciprocate vertically along the vertical hole 5. The vertical ring 24 is moved so that the position of the wire hole 19 moves vertically back and forth, thereby controlling the winding position while winding the cable 4, increasing the neatness of the cable 4 after winding. The vertical ring 24 is placed in the cleaning liquid cylinder 13, so that each positioning rod 26 enters the interior of the corresponding positioning hole 27. Then, the unused vibrating wire pressure gauge 2 is inserted into the vertical ring 24. The vibrating wire pressure gauge 2 contacts and rubs against the annular sponge 25, which can not only temporarily store the vibrating wire pressure gauge 2, but also clean the surface of the idle vibrating wire pressure gauge 2.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
