Description

Technical Field

[0001] This utility model relates to the field of piezometers, specifically a piezometer for use in complex environments. Background Technology

[0002] In fields such as geotechnical engineering and water conservancy and hydropower engineering, piezometers are important instruments for monitoring changes in groundwater level and pore water pressure. Their operational stability directly affects the accuracy of engineering safety assessment and disaster early warning. However, in complex environments such as near potential sliding surfaces, groundwater seepage sites, and the bottom and sidewalls of foundation pits, traditional piezometers face many challenges.

[0003] Traditional piezometers lack effective protection for their end cables. In areas where groundwater seeps out, the cables are constantly immersed in corrosive media, which can easily lead to insulation aging and damage, resulting in signal transmission interruption. During construction at the bottom and side walls of foundation pits, the cables are often damaged by mechanical compression, friction, or soil deformation, causing data acquisition failure. Therefore, it is necessary to design a piezometer for complex environments to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a piezometer for use in complex environments to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a piezometer for complex environments, comprising a piezometer body, a shielded cable connected to one side of the piezometer body, a protective sleeve fitted over the shielded cable, and multiple elastic support strips adhered to the outside of the protective sleeve;

[0006] A cover is fixedly installed on the outside of the protective sleeve, and multiple vertical plates are fixedly installed on the outside of the piezometer body. A rotating plate is rotatably installed on one side of the vertical plate, and a pressure block for pressing down the cover is fixedly installed at one end of the rotating plate. A perforation is opened on the surface of the rotating plate, and an abutting component for abutting the rotating plate is installed on the surface of the vertical plate.

[0007] Preferably, the abutment assembly includes a threaded rod and a guide rod, the threaded rod and the guide rod passing through the through hole (9), the threaded rod being rotatably mounted on one side of the vertical plate, the guide rod being fixedly mounted on one side of the vertical plate, and an abutment block being movably installed on the outer side of the guide rod, the threaded rod threaded through the abutment block.

[0008] Preferably, the major diameter of the threaded rod matches the outer diameter of the guide rod, the outer diameter of the guide rod is smaller than the width of the through hole, and the diameter of the abutment is larger than the width of the through hole.

[0009] Preferably, the pressing block is cylindrical, and the pressing block and the rotating plate are integrally formed.

[0010] Preferably, a sealing gasket is provided between the cover and the piezometer body, and the sealing gasket is made of rubber.

[0011] Preferably, the elastic support strips are distributed in a ring at equal intervals on the outside of the protective sleeve, and the elastic support strips are made of polyurethane rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This piezometer for complex environments uses a cover and sealing gasket to seal the piezometer body. The protective cover is then sealed to the outside of the shielded cable using sealant. The protective cover fits over the connection between the shielded cable and the piezometer body, providing a seal. High-elasticity support strips increase the strength and torsional resistance of the protective cover, protecting the cable connection and ensuring stable piezometer data acquisition.

[0014] 2. This piezometer for complex environments uses a rotating threaded rod to move a stop block outside the guide rod. The stop block does not contact the rotating plate, allowing the rotating plate to easily rotate and detach the pressure block from the cover surface. After cleaning off any residual adhesive, the protective sleeve and elastic support strip can be removed as a whole, separating the cover and sealing gasket from the piezometer body. After replacing the protective sleeve, the sealing gasket is kept against the surface of the piezometer body. By rotating the threaded rod, the stop block approaches and contacts the rotating plate, causing it to rotate. The rotating plate then presses the pressure block against the cover, ensuring the sealing gasket is tightly against the side of the piezometer body. This completes the replacement of the protective sleeve. The operation is relatively convenient, and the protective effect is ensured by replacing the protective sleeve. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a piezometer for complex environments, including a piezometer body 1, a shielded cable 2 connected to one side of the piezometer body 1, a protective sleeve 3 sleeved on the outside of the shielded cable 2, and multiple elastic support strips 4 glued to the outside of the protective sleeve 3.

[0022] A cover 5 is fixedly installed on the outside of the protective sleeve 3. Multiple vertical plates 7 are fixedly installed on the outside of the piezometer body 1. A rotating plate 8 is rotatably installed on one side of the vertical plate 7. A pressure block 13 for pressing down the cover 5 is fixedly installed at one end of the rotating plate 8. A perforation 9 is opened on the surface of the rotating plate 8. A contact component for contacting the rotating plate 8 is installed on the surface of the vertical plate 7.

[0023] Specifically, the protective sleeve 3 and elastic support strip 4 seal and protect the cable connection, and improve the strength of the cable connection, so that the piezometer can ensure the stability of data transmission in complex environments.

[0024] The contact assembly includes a threaded rod 10 and a guide rod 11, which pass through the through hole 9. The threaded rod 10 is rotatably mounted on one side of the vertical plate 7, and the guide rod 11 is fixedly mounted on one side of the vertical plate 7. A stop block 12 is movably installed on the outside of the guide rod 11. The threaded rod 10 threads through the stop block 12. The major diameter of the threaded rod 10 matches the outer diameter of the guide rod 11. The outer diameter of the guide rod 11 is smaller than the width of the through hole 9, and the diameter of the stop block 12 is larger than the width of the through hole 9. By rotating the threaded rod 10, the stop block 12 moves outside the guide rod 11. The stop block 12 does not abut against the rotating plate 8, thus facilitating the rotation of the rotating plate 8 to drive the pressure block 13 away from the surface of the cover sleeve 5, making it easy to remove the protective sleeve 3. By rotating the threaded rod 10, the stop block 12 approaches and abuts against the rotating plate 8, causing the rotating plate 8 to drive the pressure block 13 to press against the cover sleeve 5, so that the sealing gasket 6 is tightly attached to the side of the piezometer body 1, facilitating the installation of the protective sleeve 3.

[0025] Wherein: the pressure block 13 is cylindrical and is integrally formed with the rotating plate 8. A sealing gasket 6 is provided between the cover 5 and the piezometer body 1. The sealing gasket 6 is made of rubber. The pressure block 13 can press down the cover 5 so that the sealing gasket 6 is tightly attached to the surface of the piezometer body 1.

[0026] Among them, the elastic support strips 4 are distributed in a ring at equal intervals on the outside of the protective sleeve 3. The elastic support strips 4 are made of polyurethane rubber. The highly elastic support strips 4 are used to increase the strength of the protective sleeve 3, improve the torsional resistance of the protective sleeve 3, protect the cable connection, and ensure the stability of the piezometer data acquisition.

[0027] Working principle: This utility model is a piezometer for complex environments. In use, the cover 5 and sealing gasket 6 are placed on the surface of the piezometer body 1 to seal the protective cover 3 with the piezometer body 1. The end of the protective cover 3 away from the piezometer body 1 is sealed with the outside of the shielded cable 2 by the sealant. The protective cover 3 is placed at the connection position between the shielded cable 2 and the piezometer body 1 to play a sealing role. The highly elastic support strip 4 is used to increase the strength of the protective cover 3 and improve its torsional resistance, protect the cable connection, and ensure stable data acquisition of the piezometer.

[0028] If the protective sleeve 3 and the elastic support strip 4 age after prolonged use, the threaded rod 10 can be rotated to move the abutment 12 outside the guide rod 11. The abutment 12 will not contact the rotating plate 8, thus facilitating the rotation of the rotating plate 8 to move the pressure block 13 away from the surface of the cover sleeve 5. After cleaning the residual adhesive, the protective sleeve 3 and the elastic support strip 4 can be removed as a whole, and the cover sleeve 5 and the sealing gasket 6 can be separated from the piezometer body 1. After replacing the protective sleeve 3, the sealing gasket 6 is kept close to the surface of the piezometer body 1. By rotating the threaded rod 10, the abutment 12 is moved close to and contacts the rotating plate 8 to rotate. The rotating plate 8 drives the pressure block 13 to press the cover sleeve 5, so that the sealing gasket 6 is tightly attached to the side of the piezometer body 1. This completes the replacement of the protective sleeve 3. The operation is relatively convenient, and the protective effect is ensured by replacing the protective sleeve 3.
