Description

A groundwater level monitoring instrument

Technical Field

The utility model relates to the technical field of water level monitoring instruments, in particular to an underground water level monitoring instrument.

Background Art

Groundwater level monitoring refers to the use of modern scientific and technological means to monitor and analyze groundwater levels in order to better understand the distribution, flow and changes of groundwater. Groundwater level monitoring can help us better understand the utilization of water resources and changes in the hydrogeological environment, and plays an important role in water conservancy projects, urban planning and environmental protection.

The main body of the existing groundwater level monitor is usually placed in a waterproof and dustproof casing to protect the device from interference and damage from the external environment. This casing is usually composed of two detachable parts, and a sealing gasket is set at the connection to ensure the sealing of the entire casing. At the connection between the two casings, the sealing effect is achieved by pressing the two casings together, and the sealing is provided with the help of the sealing gasket material. Over time, the sealing gasket material may age, resulting in a gradual deterioration of the sealing effect. However, the existing casing connection structure does not provide a design structure for fastening the sealing gasket, which will seriously shorten the service life of the sealing gasket because it is not conducive to the long-term and stable use of the sealing gasket.

Therefore, it is necessary to provide a groundwater level monitor to solve the above technical problems.

A push rod 17 is fixedly installed between the limit blocks 15, and the push rod 17 is slidably connected to the inner wall of the fixed cylinder 13. A spring 14 is fixedly connected between one end of the push rod 17 located inside the fixed cylinder 13 and the top of the inner wall of the fixed cylinder 13. An annular push plate 16 is fixedly installed at the bottom end of the push rod 17, and the annular push plate 16 is slidably connected to the inner wall of the annular fastening groove 7.

A threaded barrel 10 is fixedly mounted on the top of the first connecting member 8 , a threaded column 18 is threadedly connected to the threaded barrel 10 , a protective cover 11 is fixedly mounted on one end of the threaded column 18 , and a sealing ring 19 is bonded to one side of the protective cover 11 .

In one embodiment, a groove adapted to the threaded barrel 10 is opened on the top of the second connecting member 9, so that the threaded barrel 10 can fit perfectly at the connection between the second connecting member 9 and the second connecting member 8 without hindering the closure of the second connecting member 9 and the second connecting member 8.

In one of the preferred embodiments, the first connecting member 8 and the second shell 2 are an integrally formed structure, and the first shell 1 and the second connecting member 9 are an integrally formed structure, which improves the structural strength of the first connecting member 8 and the second connecting member 9, simplifies the manufacturing and installation process, and has high practicality.

In one embodiment, the second housing 2 and the annular groove 5 are integrally formed, and the first housing 1 and the annular fastening groove 7 are integrally formed.

In one of the preferred embodiments, the thickness of the sealing gasket 6 is greater than the depth of the annular groove 5, ensuring that the sealing gasket 6 can be inserted into the annular fastening groove 7 to achieve a good sealing effect.

The working principle of the utility model is as follows: the contents not described in detail in this specification belong to the prior art known to those skilled in the art. When installing the first monitoring instrument body 3 and the second monitoring instrument body 4, first unfold the first shell 1 and the second shell 2 and lay them flat on the platform, fix the first monitoring instrument body 3 to the inside of the first shell 1 by bolts, and fix the second monitoring instrument body 4 to the inside of the second shell 2 by bolts. After the first monitoring instrument body 3 and the second monitoring instrument body 4 are fixed, the corresponding wires are connected. After everything is ready, the first shell 1 is covered on the top of the second shell 2. At this time, the second connecting piece 9 on the first shell 1 corresponds to the first connecting piece 8 on the second shell 2. In the process of closing the first shell 1 and the second shell 2, the sealing gasket 6 will enter the inside of the annular fastening groove 7 and produce an extrusion effect on the annular push plate 16, so that the annular push plate 16 drives the push rod 17 to slide to the inside of the fixing tube 13 and squeeze the spring 14. The first connecting piece 8 and the second connecting piece 9 are subsequently fixed by bolts. During the use of the water level monitor, the sealing gasket 6 at the connection between the first shell 1 and the second shell 2 will be firmly fitted at the connection between the first shell 1 and the second shell 2 under the elastic action of the spring 14. Even after long-term use, as the sealing gasket 6 ages, the elastic action of the spring 14 will continue to exert pressure on the sealing gasket 6, and the design of the annular push plate 16 will increase the elastic squeezing effect on the sealing gasket 6, which enables the sealing gasket 6 to always maintain a high degree of fit with the first shell 1 and the second shell 2. This fastening design plays an important role in the sealing gasket 6 and greatly extends the service life of the sealing gasket 6. It ensures that the sealing gasket 6 can work stably for a long time. During the use of the water level monitor, this fastening design improves the durability and sealing performance of the sealing gasket 6, and effectively protects the equipment from interference and damage from the external environment.

After the first shell 1 and the second shell 2 are fixed, the protective cover 11 is directly sleeved on the connection between the second connecting member 9 and the first connecting member 8, and the protective cover 11 is rotated to screw the threaded column 18 inside the protective cover 11 into the inside of the threaded barrel 10. As the threaded column 18 is screwed into the inside of the threaded barrel 10, the protective cover 11 can be fixed to the outside of the connection between the first connecting member 8 and the second connecting member 9, and at the same time, the sealing ring 19 on one side of the protective cover 11 is tightly against the outer surface of the connection between the first shell 1 and the second shell 2, and the first connecting member 8 and the second connecting member 9 are sealed inside the protective cover 11 to avoid leakage of the first connecting member 8 and the second connecting member 9. At the same time, the disassembly and assembly method of the protective cover 11 is simple, easy to operate, and convenient for people to use. The sealing protection of the first connecting member 8 and the second connecting member 9 and the fixing bolts thereon reduces the speed of oxidation and aging. When the water level monitor is overhauled and the first shell 1 and the second shell 2 are disassembled, the first shell 1 and the second shell 2 can be easily disassembled without worrying about the problems caused by rusting of the connecting bolts.
