The installation is also cumbersome and inconvenient for subsequent maintenance. A piezometer installation device for the piezometer tube is proposed, which is convenient for installing the piezometer into the piezometer tube and can make the data measured by the piezometer accurate.

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] A piezometer mounting device for a piezometer tube, such as Figure 1-Figure 4As shown, it includes a sleeve 1 and a flip cover 2 rotatably connected to the sleeve 1, the sleeve 1 is provided with a plurality of water-permeable holes 11, the flip cover 2 and the sleeve 1 are fixed by a fixing assembly, the flip cover 2 is provided with a through hole 21, a support plate 5 is arranged in the sleeve 1, a piezometer 6 is placed on the support plate 5, a data line 7 is arranged on the piezometer 6, the data line 7 is led out through the through hole 21, the piezometer 6 installation device also includes a line fixing mechanism 8 for fixing the data line 7, the line fixing mechanism 8 includes a plurality of sliding sleeves 82 arranged on the flip cover 2, a sliding frame 83 is slidably arranged on the sliding sleeve 82, a clamp 85 is arranged on the sliding frame 83, a first spring 84 is connected between the sliding sleeve 82 and the adjacent sliding frame 83, a plurality of extrusion members 81 are arranged on the sleeve 1, and the extrusion member 81 cooperates with the adjacent sliding frame 83.

[0028] First, the operator can place the osmometer 6 on the support plate 5, and then lead the data line 7 of the osmometer 6 out of the through hole 21 of the flip cover 2. Then the operator can rotate the flip cover 2 to make the flip cover 2 contact with the sleeve 1. When the flip cover 2 is rotated, the flip cover 2 will drive the sliding sleeve 82, the sliding frame 83, the first spring 84 and the clamp 85 to rotate together. When the sliding frame 83 rotates to contact with the extrusion member 81, the extrusion member 81 will push the sliding frame 83 to move in the direction close to the data line 7, the first spring 84 is compressed, and the sliding frame 83 moves close to the data line 7. The movement in the direction of the clamp 85 will drive the clamp 85 to move toward the direction close to the data line 7, thereby making the clamp 85 contact with the data line 7, and thus clamping the data line 7 through the clamp 85 to prevent the data line 7 from loosening when the osmometer 6 installation device is placed in the pressure measuring tube, resulting in poor contact between the data line 7 and the osmometer 6. After the clamp 85 clamps the data line 7, the operator can fix the flip cover 2 on the sleeve 1 by operating the fixing component. After fixing the flip cover 2, the operator can place the osmometer 6 installation device into the pressure measuring tube to make the bottom of the sleeve 1 contact with the bottom of the pressure measuring tube. Since the bottom of the casing 1 is separated from the support plate 5 by a distance, the piezometer 6 is also separated from the bottom of the piezometer tube by a distance, so the silt at the bottom of the piezometer tube will not be immersed in the piezometer 6 to affect the piezometer 6. When the piezometer 6 needs to be taken out, the operator can first take out the piezometer 6 installation device from the piezometer tube, then operate the fixing assembly to make the flip cover 2 no longer fixed on the casing 1, and then rotate the flip cover 2 to make the flip cover 2 away from the casing 1. When the flip cover 2 is rotated, the flip cover 2 will drive the sliding sleeve 82, the sliding frame 83, and the first spring 84 to move. 84 and the clamp 85 will rotate together. When the sliding frame 83 rotates to the point where it is no longer in contact with the extrusion member 81, the first spring 84 is reset. The reset of the first spring 84 will drive the extrusion member 81 to move away from the data line 7. The movement of the extrusion member 81 away from the data line 7 will drive the clamp 85 to move away from the data line 7, thereby making the clamp 85 no longer in contact with the data line 7. After the clamp 85 no longer in contact with the data line 7, the operator can pass the data line 7 through the through hole 21. After the data line 7 is passed through, the operator can remove the piezometer 6 from the support plate 5.

[0029] To sum up, the piezometer 6 installation device can separate the piezometer 6 from the bottom of the pressure measuring tube by setting the casing 1 and the support plate 5, so that the piezometer 6 can be separated by a distance from the bottom of the pressure measuring tube, so that the silt at the bottom of the pressure measuring tube will not be immersed in the piezometer 6 and affect the piezometer 6, and the height of the piezometer 6 and the bottom of the casing 1 is set to form a fixed height, that is, when the piezometer 6 installation device is placed in the pressure measuring tube, the bottom of the casing 1 contacts the bottom of the pressure measuring tube, and the height of the piezometer 6 and the bottom of the pressure measuring tube also forms a fixed height. Therefore, when the piezometer 6 is measured in the pressure measuring tube for a long time, the depth data of the piezometer 6 will not change, thereby improving the stability of the measurement data of the piezometer 6, and then through the setting of the line fixing mechanism 8, the data line 7 can be clamped and loosened by rotating the flip cover 2, thereby achieving the convenient operation of fixing the data line 7 and effectively preventing the connection between the data line 7 and the piezometer 6 from loosening, further improving the stability of the measurement data of the piezometer 6.

[0030] The fixing assembly includes a threaded sleeve 3 and a bolt 4 . The threaded sleeve 3 is arranged on the sleeve 1 , and the flip cover 2 is connected to the threaded sleeve 3 via the bolt 4 .

[0031] When the operator operates the fixing assembly, when it is necessary to fix the flip cover 2 on the sleeve 1, the operator first rotates the bolt 4 to make the bolt 4 pass into the threaded sleeve 3, thereby fixing the flip cover 2 on the sleeve 1. When it is no longer necessary to fix the flip cover 2 on the sleeve 1, the operator only needs to rotate the bolt 4 away from the threaded sleeve 3 so that the bolt 4 no longer contacts the threaded sleeve 3, thereby the flip cover 2 will no longer be fixed on the sleeve 1.

[0032] The sliding frame 83 is provided with a ball bearing 86 .

[0033] Wherein, by disposing the ball bearing 86, when the flip cover 2 rotates, the ball bearing 86 will contact with the extrusion member 81, and the friction force can be reduced by disposing the ball bearing 86.

[0034] The clamping member 85 is arc-shaped.

[0035] Among them, by arranging the clamp 85 in an arc shape, the clamp 85 can be adapted to the data line 7, so that the clamp 85 can clamp the data line 7 more firmly.

[0036] like Figure 5-Figure 6 As shown, the piezometer 6 mounting device also includes a fixing mechanism 9, which includes a baffle 94 arranged on the flip cover 2 and an air cylinder 91 arranged on the sleeve 1, an extrusion rod 92 is slidably arranged in the air cylinder 91, and the extrusion rod 92 is extruded and matched with the baffle 94, a second spring 93 is connected between the air cylinder 91 and the extrusion rod 92, and an expansion bag 95 is arranged in the sleeve 1, and the expansion bag 95 is connected to the air cylinder 91.

[0037] Furthermore, when the flip cover 2 rotates in the direction approaching the sleeve 1, it will drive the baffle 94 to rotate. When the baffle 94 rotates, it will contact the extrusion rod 92 to squeeze the extrusion rod 92, the second spring 93 will be compressed, the extrusion rod 92 will move downward, the extrusion rod 92 moves downward to squeeze the air in the air cylinder 91 into the expansion bag 95, the expansion bag 95 will expand and contact the osmometer 6 in the sleeve 1, thereby fixing the osmometer 6 to prevent the osmometer 6 from moving during long-term measurement, thereby causing inaccurate measured data. When the flip cover 2 rotates in the direction away from the sleeve 1, the baffle 94 will also rotate with it, the baffle 94 will no longer contact the extrusion rod 92, the second spring 93 will reset, and the resetting of the second spring 93 will drive the extrusion rod 92 to reset, the gas in the expansion bag 95 will return to the air cylinder 91, the expansion bag 95 will no longer expand, and the expansion bag 95 will no longer contact the osmometer 6.

[0038] like Figure 7 As shown, the piezometer 6 installation device also includes an adjusting mechanism 10, which includes a sliding sleeve 103 slidably arranged on the casing 1 and a driving component for driving the sliding sleeve 103 to move, and the driving component includes a threaded seat 101 arranged on the casing 1 and a screw 102 threadedly connected to the threaded seat 101, and the screw 102 is rotatably connected to the sliding sleeve 103.

[0039] When the operator needs to adjust the height between the bottom of the piezometer 6 and the piezometer 6, the operator can first rotate the screw 102 in the forward direction. The rotation of the screw 102 will drive the sliding sleeve 103 to move downward, and then the piezometer 6 installation device is placed in the piezometer so that the bottom of the sliding sleeve 103 contacts the bottom of the piezometer. Thus, the distance between the piezometer 6 and the bottom of the piezometer will be longer. When the distance between the piezometer 6 and the bottom of the piezometer needs to be shortened, the operator only needs to rotate the screw 102 in the reverse direction. The reverse rotation of the screw 102 will drive the sliding sleeve 103 to move upward, and then the piezometer 6 installation device is placed in the piezometer so that the bottom of the sliding sleeve 103 contacts the bottom of the piezometer. Thus, the distance between the piezometer 6 and the bottom of the piezometer is shortened.
