Description

Adjustable Groundwater Level Monitoring Device

technical field

The utility model relates to the field of water level monitoring, in particular to an adjustable underground water level monitoring device.

Background technique

At present, the instrument used to observe the groundwater level of foundation pits is a steel ruler water level gauge. When measuring the water level, it is necessary to extend the end of the steel ruler with the probe into the pre-buried water level observation pipe of the foundation pit. When the probe touches the water, the steel ruler water level gauge will emit a prompt sound, and then record the reading of the steel ruler to measure the water level value. In actual use of this water level observation method, the steel ruler needs to be retracted and retracted for each measurement, which is inconvenient to operate, and the rotating shaft surrounded by the steel ruler is also easily damaged. In addition, due to the mud and sand mixed in the water level observation pipe of the foundation pit, the probe of the steel ruler water level gauge often contacts the mud and sand, and is also easily damaged. At present, the steel ruler water level gauge commonly used in engineering is 30 meters in size, which is heavy and inconvenient to carry and carry.

The marks of each part in the accompanying drawings are as follows: 1. water level pipe, 2. floater, 3. metal snap ring, 4. fixed frame, 41. frame, 42. bottom plate, 5. level bubble.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1, an adjustable groundwater level monitoring device, including a water level pipe 1 buried in the ground, the water level pipe 1 is provided with reflective floating objects 2, the upper end of the water level pipe 1 is covered with a metal snap ring 3, the metal snap ring A fixed frame 4 for placing the rangefinder is installed vertically on the ring 3. The fixed frame 4 includes a frame 41 and a bottom plate 42 vertically arranged with the frame 41. The bottom plate 42 is magnetic and is attached to the metal snap ring 3, and the metal snap ring 3. Move left and right to adjust the position of the rangefinder. It is suitable for large-aperture water level observation wells, which can avoid foreign objects in the well and improve data accuracy through multiple measurements.

In addition, the bottom plate 42 is perpendicular to the upper surface of the metal snap ring 3 , and a leveling angle screw can also be added on the metal snap ring to adjust the height to achieve measurement at different heights.

In addition, the frame 41 is a rectangular parallelepiped frame structure.

In addition, the upper surface of the frame 41 is provided with a leveling bubble 5 .

In addition, the surface of the floating object 2 is coated with fluorescent substances, and the floating object can also be other objects with a smooth surface that can float on the water surface, such as reflective film, reflective plastic board and the like.

The specific work of the adjustable groundwater level monitoring device of the utility model is as follows: set the metal snap ring 3 on the upper end of the water level pipe 1, then place the fixed frame 4 on the metal snap ring 3, and move the fixed frame 4 to adjust the level of the distance meter The position can be measured multiple times, which is suitable for large-aperture water level observation wells, which can avoid foreign objects in the well, and multiple measurements can improve data accuracy. The key point is that before the water level pipe is buried, test whether the nozzle of the top water level pipe is flat, and the water level pipe should not be deformed greatly when it is buried.

Different from the prior art, the adjustable underground water level monitoring device of the utility model can simplify the structure, measure at multiple positions, be convenient to use, and have high detection accuracy.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the content of the specification of the utility model, or directly or indirectly used in other related technologies Fields are all included in the scope of patent protection of the utility model in the same way.
