Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering, and more specifically, to a water conservancy engineering uplift pressure measuring pipe. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and valuable resource for human production and life, but its natural state does not fully meet human needs. In water conservancy projects, it is often necessary to measure the uplift pressure, and the tools required are mainly uplift pressure measuring tubes.

[0003] In the process of using the existing uplift pressure gauge pipe, because it is necessary to ensure stable and accurate pressure measurement, a filter device is often used to filter the water before measuring the pressure. Impurities in the water can easily cause pipes or meshes to be clogged, and the filter device is often fixedly connected to the pressure gauge pipe, making it difficult to remove it to clean the clogged pipes and meshes, which may cause the pressure gauge pipe to malfunction and inaccurate measurement data to occur.

[0004] After searching, a Chinese patent with announcement number CN214407868U discloses a hydraulic engineering pressure gauge. The utility model is provided with a positioning plate and a fixing block. The elastic rubber pad is squeezed by pressing the mounting plate downward, and then the positioning plate is rotated so that the positioning hole on the positioning plate is separated from the fixing block, thereby completing the separation of the mounting plate and the outer cylinder, realizing the disassembly of the inner cylinder, facilitating the removal of the filter cylinder and cleaning the blocked pipes and meshes, ensuring the cleanliness of the filter cylinder, and thus avoiding the phenomenon of malfunction of the pressure gauge and inaccurate measurement data.

[0005] However, when the above-mentioned pressure measuring tube is actually used, during the installation process of the pressure measuring tube, the pressure measuring tube may collide with an object, causing the position of the filter cylinder and the outer cylinder to shift, thereby affecting the deviation of the lift pressure detection. Utility Model Content

[0008] The top of the fixing plate is connected with thesaurus and the bottom of the fixing plate is connected with the fixing plate, and the fixing plate is connected with the fixing ball on the top of the fixing plate.

[0009] By adopting the above technical solution: multiple arc-shaped limit rods can support the chuck at multiple points, so that the chuck can maintain a good fit with the sealing gasket, and the vibration of the pressure gauge tube during installation and positioning can be avoided to affect the sealing of the connection between the outer tube and the insert.

[0010] As a further description of the above technical solution: a guide mechanism is arranged inside the cannula, and the guide mechanism includes a line tube, the outer side of the line tube is fixedly connected to the top of the cannula, the bottom of the line tube is fixedly connected to a pressure detector, the top of the pressure detector is fixedly connected to a connecting ring, a support spring is installed on the outer side of the connecting ring, and the outer side of the connecting ring is rotatably connected to a support frame.

[0011] By adopting the above technical solution: a plurality of support frames can assist in supporting the position of the pressure detector inside the cannula, thereby preventing the pressure detector from colliding with the inner wall of the cannula.

[0012] As a further description of the above technical solution: two blocks are fixedly connected to the outside of the insert tube, a clamping ring is rotatably connected to the outside of the insert tube, a sliding groove is opened on the inner wall of the clamping ring, two retaining beads are installed inside the clamping ring, and a filter cartridge is fixedly connected to the bottom of the clamping ring.

[0013] By adopting the above technical solution: the filter cartridge can be quickly and conveniently fixed and connected, which speeds up the efficiency of installation and cleaning.

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting a stable positioning mechanism, compared with the prior art, multiple arc-shaped limit rods support and position the chuck at multiple points, so that the chuck can maintain a stable fit with the sealing gasket, so that the pressure measuring tube of the lifting pressure can maintain good sealing during the installation process, and avoid the adverse effect of vibration on the sealing of the pressure measuring tube;

[0016] 2. By setting up a guide mechanism, compared with the prior art, it is possible to avoid the pressure detector from colliding with the cannula during the installation and positioning process, so that the pressure detector can maintain a better use effect and maintain the pressure detector's detection effect on the lifting pressure.
