Description

Technical Field

[0001] This utility model belongs to the field of seepage pressure measuring device technology, specifically, it relates to a seepage pressure measuring device for hydraulic dams. Background Technology

[0002] A piezometer, also known as a pore water pressure gauge, is a sensor used to measure the pore water pressure or seepage pressure inside a structure. Piezometers have a wide range of applications, including measuring seepage pressure in dam bodies, phreatic lines, seepage pressure around dams, uplift pressure at dam foundations, piezometer water levels and dry borehole depths in tailings ponds, and measurements of slopes, canals, and riverbanks. However, the inventors have discovered the following problems with its use in existing technologies:

[0003] Existing technology discloses a seepage monitoring device (202222271216.4), including a pressure sensor. The pressure sensor is mounted on an extender, and a connecting rod is installed on the top of the extender. A top cap is installed on the top of the connecting rod. The extender extends movably into an inner tube with a top opening. An interconnection port corresponding to the position of the pressure sensor is opened on the bottom side wall of the inner tube. A base plate is installed inside the inner tube below the interconnection port. By using an inner tube in conjunction with the pressure sensor, the existing technology can effectively solve the problems of the sensor signal line being too soft and the obstruction of mud and water affecting the sensor's positioning when it is inserted into the pressure measuring tube. By using a barbed rod with hooks, when silt accumulates in the pressure measuring tube, it can rely on the compression formed by the inner tube when it is inserted, and then rely on the barbed rod to fix it. When the inner tube is pulled out, a large amount of silt can be removed, thereby further reducing the occurrence of insufficient elevation due to silt.

[0004] A piezometer typically has a pressure sensor installed at the end furthest from the transmission cable for measurement and electrical signal transmission. Before use, the piezometer needs to be submerged in water to saturate the pressure sensor. The piezometer estimates the water level by measuring the pressure of the groundwater. To ensure accurate measurement of groundwater pressure, the piezometer needs to be fully saturated in water so that its internal components can fully adapt to changes in water pressure and temperature. However, prior to current technology, piezometers were not submerged for immediate use, making them unavailable to staff and presenting certain drawbacks.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0030] like Figure 1 and Figure 2 As shown, a seepage pressure gauge for a hydraulic dam includes:

[0031] A pressure measuring tube 10 is provided, and a pressure sensor 11 is fixedly installed on the bottom wall of the pressure measuring tube 10. A limiting groove 12 is provided on the upper side wall of the pressure measuring tube 10.

[0032] A wetting device is provided on the side wall of the pressure measuring tube 10 to wet the pressure sensor 11. The wetting device includes a wetting tube 13, and the top wall of the wetting tube 13 is hollow.

[0033] A limiting device is provided on the top wall of the immersion tube 13 to limit the pressure sensor 11 within the cavity of the immersion tube 13. The limiting device includes two limiting plates 15.

[0034] It is worth noting that the pressure measuring tube 10, the seepage pressure sensor 11, and the limiting groove 12 have all been disclosed in a seepage monitoring device (202222271216.4), and will not be described in detail here.

[0035] In practical use, before using the pressure measuring tube 10, it is necessary to ensure that the pressure sensor 11 is completely wetted with water. This ensures that the pressure measuring tube 10 can correctly respond to changes in liquid pressure. The immersion device can wet the pressure sensor 11 with water, making it convenient for staff to use at any time. The limiting device can limit the pressure measuring tube 10, making it convenient for the immersion device to wet the pressure sensor 11.

[0036] In summary, by setting up an immersion device and a limiting device, the pressure sensor 11 can be immersed in the immersion device for easy use by the staff at any time, and the pressure measuring tube 10 can be limited by the limiting device to facilitate the immersion of the pressure sensor 11. Compared with the existing technology, it has the characteristics of being easy to use and having a simple structure.

[0037] like Figure 3 As shown, a rubber ring 26 is fixedly installed at the upper position inside the cavity of the immersion tube 13, and the inner sidewall of the rubber ring 26 has the same radius as the sidewall of the pressure measuring tube 10.

[0038] In practical use, when the pressure measuring tube 10 is inserted into the cavity of the immersion tube 13 through the rubber ring 26, the inner wall of the rubber ring 26 will fit tightly against the side wall of the pressure measuring tube 10 to achieve a sealing effect. The pressure sensor 11 is then immersed in water by injecting water into the cavity of the immersion tube 13, making it convenient for staff to use.

[0039] In summary, by setting up the immersion tube 13, rubber ring 26, pressure sensor 11 and pressure measuring tube 10, the tight fit between the rubber ring 26 and the pressure measuring tube 10 can achieve a sealing effect. By injecting water into the cavity of the immersion tube 13 to immerse the pressure sensor 11, the staff can use the pressure sensor 11 at any time. It is convenient to use and has a simple structure.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, two first fixing plates 14 are fixedly installed on the top wall of the immersion tube 13. The left and right side walls of the two first fixing plates 14 are hollowed out. A second fixing plate 27 is installed on the upper wall of the side of the two first fixing plates 14 that are close to each other. The side wall of the two second fixing plates 27 that are close to each other is arc-shaped and fits against the side wall of the pressure measuring tube 10. The bottom wall of the two L-shaped plates 17 is hollowed out.

[0041] The two limiting plates 15 are respectively disposed above the cavities of the two first fixed plates 14. A movable plate 16 is fixedly installed on the side wall of the two limiting plates 15 that are far apart from each other. Two L-shaped plates 17 are fixedly installed on the side wall of the two movable plates 16 that are far apart from each other. A first displacement hole 24 is opened on the front and rear side walls above the first fixed plate 14. The ends of the two L-shaped plates 17 that are far apart from each other are movably installed in the cavities of the corresponding first displacement holes 24.

[0042] The side walls of the two movable plates 16 that are far apart from each other are hollowed out. A lever 18 is provided below the movable plate 16. A torsion spring 19 is fixedly installed on the front and rear side walls of the lever 18 and the front and rear side walls of the cavity of the first fixed plate 14, respectively.

[0043] A connecting rod 23 is fixedly installed on the front and rear side walls above the lever 18, penetrating the front and rear side walls inside the cavity of the movable plate 16. The connecting rod 23 is movably connected to the movable plate 16 at the penetration point.

[0044] A through hole 22 is provided on the lower front and rear side walls of the lever 18. A movable rod 20 is movably installed in the cavity of the through hole 22. A second displacement hole 25 is provided on the lower front and rear side walls of the first fixed plate 14. The movable rod 20 passes through the second displacement hole 25. A handle 21 is fixedly installed at the front and rear ends of the movable rod 20. The two handles 21 are located at the front and rear sides of the first fixed plate 14, respectively.

[0045] In practical use, when the operator pulls the two sets of handles 21 on the left and right sides towards each other, it will move the two moving rods 20 towards each other. The movement of the two moving rods 20 will cause the lever 18 to rotate around the torsion spring 19. The second displacement hole 25 allows the moving rods 20 to move parallel, and the through hole 22 ensures that the movement of the moving rods 20 does not affect the rotation of the lever 18. When 28 rotates, it will cause the two moving plates 16 to move away from each other. The L-shaped plate 17 can pass through the first... The moving hole 24 moves in parallel, and the parallel movement of the L-shaped plate 17 can drive the moving plate 16 to move in translation, which in turn drives the limiting plate 15 to move in translation. Then, the operator can insert the pressure sensor 11 into the cavity of the immersion tube 13. After the operator releases the handle 21, the lever 18 can be rotated and reset by the force of the torsion spring 19, so that the two limiting plates 15 are brought closer to each other and inserted into the cavity of the limiting groove 12, thereby limiting the pressure measuring tube 10. The second fixing plate 27 and the first fixing plate 14 can both guide the movement of the moving plate 16.

[0046] In summary, by setting up a limiting groove 12, a first fixing plate 14, a limiting plate 15, a moving plate 16, an L-shaped plate 17, a lever 18, a torsion spring 19, a moving rod 20, a handle 21, a through hole 22, a connecting rod 23, a first displacement hole 24, a second displacement hole 25, a rubber ring 26, and a second fixing plate 27, the operator can pull the two handles 21 closer together and the two limiting plates 15 further apart, and then the pressure measuring tube 10 can be inserted into the cavity of the immersion tube 13. The two limiting plates 15 are connected to the limiting groove 12 to limit the pressure measuring tube 10, so that the pressure measuring tube 10 will not detach from the immersion tube 13. It is convenient to use and has a simple structure.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
