Abstract

The utility model discloses a water level measuring instrument for a dewatering well, which comprises a foam board and a steel needle. The outer wall of the well pipe of the dewatering well is provided with a water level reading, the foam board floats on the water surface of the dewatering well, and one end of the steel needle is connected with the foam board. The other end of the steel needle points to the water level reading on the outer wall of the well pipe of the precipitation well. The utility model has a reasonable design structure and can effectively solve the inaccurate and time-consuming situation of traditional measurement. Using the buoyancy of water, it only needs to take a reading every two hours. The surveyor does not need to throw the float into the precipitation well and lift it up again and again, which achieves the purpose of humanized management.

Description

A kind of precipitation well water level measuring instrument

technical field

The utility model relates to the field of precipitation well measurement, in particular to a water level measuring instrument for a precipitation well with a small precipitation depth.

Background technique

The main way to measure the current precipitation well is to carry out manually. The float (including foam board, plastic bottle) is tied with hemp rope and thrown into the precipitation well. The water level can be judged by the feeling of reaching the water surface. The length measures the height of the water level. This kind of measurement method is extremely inaccurate, it all depends on the hand feeling, and the measurement is time-consuming and laborious, which is not economical and applicable.

Utility model content

The purpose of the utility model is to provide a precipitation well water level measuring instrument which can accurately measure the water level.

The technical scheme adopted in the utility model is:

A water level measuring instrument for a precipitation well, which includes a foam board and a steel needle with water level readings engraved on the outer wall of the well pipe of the precipitation well, the foam board floats on the water surface of the precipitation well, one end of the steel needle is connected with the foam board, and the other end of the steel needle The water level reading on the outer wall of the well pipe of the precipitation well.

In the above solution, the steel needle includes a connecting section and an indicating section perpendicular to each other, the connecting section is connected with the foam board, and the indicating section points to the water level reading on the outer wall of the well pipe of the precipitation well.

In the above solution, the connecting section of the steel needle is connected to the middle of the foam board.

The principle of the utility model is: between the buoyancy of the water, the foam board floats up and down, and the steel needle also floats thereupon, so that a group of readings can be obtained, which can be converted into a high water level of the precipitation well.

Beneficial effects of the utility model: the utility model has a reasonable design and structure, and can effectively solve the inaccurate and time-consuming situation of traditional measurement. Using the buoyancy of water, it only needs to take a reading every two hours. The surveyor does not need to throw the float into the precipitation well and lift it up again and again, which achieves the purpose of humanized management.

Description of drawings

Fig. 1 is a schematic structural diagram of a water level measuring instrument for a precipitation well provided by an embodiment of the present invention.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, it is the dewatering well water level measuring instrument that the utility model embodiment provides, and it comprises foam board 2 and steel needle 3, and water level reading 4 is engraved on the dewatering well pipe outer wall 1, and foam board 2 floats on the precipitation On the well water surface 5, one end of the steel needle 3 is connected with the foam board 2, and the other end of the steel needle 3 points to the water level reading 4 of the outer wall of the well pipe of the dewatering well.

In this embodiment, the steel needle 3 includes a connecting section perpendicular to each other and an indicating section, the connecting section is connected with the foam board 2, and the indicating section points to the water level reading on the outer wall of the well pipe of the dewatering well. In this embodiment, the connecting section of the steel needle 3 is connected to the middle of the foam board 2 . Foam board 2 is a semicircular foam board with a smooth center. The steel needle 3 itself has excellent rigidity and light weight, and the length of the connecting section is between 5-8 meters.

The steel needle 3 can float up and down with the foam board 2, so the steel needle 3 can float up and down with the water, thereby reading the water level of the dewatering well.

It should be noted that those of ordinary skill in the art should understand that the technical solution of the utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solution of the utility model, which should be covered by the rights of the utility model. within the required range.
