Problems solved by technology

The piezometer is mainly composed of a pressure introduction component, a vibrating wire sensing component, a casing and a cable. And the electromagnetic coil, if the poor sealing of the shell causes water to enter the inner cavity, the vibrating wire and the electromagnetic coil will stop working, which will have a significant impact on the observation results of the vibrating wire induction component. The existing piezometer has a technical problem of poor sealing

Embodiment 1

[0027] Please refer to figure 1 , this embodiment provides a piezometer, including a pressure introduction component 100, a vibrating wire sensing component 200, a housing 300, a cable 400 and a cable sealing component 500; the vibrating wire sensing component 200 is fixedly arranged in the inner cavity of the housing 300, The vibrating wire induction assembly 200 includes a vibrating wire 210 and an electromagnetic coil 220 , the vibrating wire 210 is disposed along the axial direction of the housing 300 , and the electromagnetic coil 220 is disposed between the vibrating wire 210 and the housing 300 . If the electromagnetic coil 220 adopts double coils, the damage of one of the coils will lead to failure of the whole piezometer. In this embodiment, the electromagnetic coil 220 adopts a single coil to improve the stability of the piezometer and prolong the service life.

[0028] The pressure introduction assembly 100 includes a water-permeable component 110 and an elastic mem...

Abstract

The invention relates to the field of engineering safety monitoring instruments and discloses an osmometer. The osmometer comprises a pressure introduction assembly, a vibration wire induction assembly, a shell, a cable and a cable sealing component, wherein the vibration wire induction assembly is fixedly arranged in an inner cavity of the shell, a vibration wire is arranged along the axial direction of the shell, the pressure introduction assembly comprises a water-permeable part and an elastic film plate, the elastic film plate is arranged to cover an opening in one end of the shell, and the water-permeable part is arranged on one side, far from the shell, of the elastic film plate; two ends of the vibration wire are respectively connected to a first clamping seat and a second clampingseat, and the first clamping seat is arranged close to the elastic film plate and is fixedly connected with the elastic film plate; the cable sealing component is arranged to cover an opening in the other end of the shell, and the cable penetrates into the cable sealing component; and a middle sealing component is further arranged in the inner cavity of the shell and is located between the secondclamping seat and the cable sealing component, and the space between the middle sealing component and the cable sealing component is filled with a sealing material. The osmometer has the beneficial effects of good sealing property, long service life and accurate testing result.

Description

technical field [0001] The invention relates to the field of engineering safety monitoring instruments, in particular to a piezometer. Background technique [0002] The piezometer is buried in hydraulic structures or other concrete structures and soil for a long time to measure the seepage (pore) water pressure inside the structure or soil. The piezometer is mainly composed of a pressure introduction component, a vibrating wire sensing component, a casing and a cable. And the electromagnetic coil, if the poor sealing of the housing causes water to enter the inner cavity, the vibrating wire and the electromagnetic coil will stop working, which will have a significant impact on the observation results of the vibrating wire induction component. The existing piezometer has a technical problem of poor sealing. Contents of the invention [0003] The object of the present invention is to provide a piezometer with good sealing performance, long service life and accurate test resu...
