Water taking device and using method thereof

Abstract

The invention provides a water taking device and a using method thereof. The water taking device comprises a barrel, an extension pipe, a first connecting rod, a water inlet plug and a balancing weight. Wherein one end of the extension pipe is connected with the first water inlet part of the barrel, and the other end of the extension pipe is provided with a second water inlet part; the first connecting rod penetrates through a connecting rod mounting hole in the top of the barrel, the bottom end of the first connecting rod extends out of the bottom of the barrel, a water inlet plug is mounted at the bottom end of the first connecting rod and used for sealing the first water inlet part or the second water inlet part, and a balancing weight is hung at the bottom of the water inlet plug. During use, the water inlet plug moves downwards under the gravity action of the first connecting rod and the balancing weight and is separated from the hollow cylinder and the extension pipe to form a water inlet channel; after water taking is completed, the pull rope is tightened, the connecting rod is lifted, and then the water inlet plug can be driven to seal the water inlet channel. The device can be used for sampling a water sample deeper below the liquid level, does not need an additional power source, and is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of liquid sampling, and in particular relates to a water taking device and a using method thereof. Background technique [0002] In the process of environmental monitoring, water quality sampling operations are often involved, that is, sampling water bodies in rivers, rivers, lakes, wells, etc. At present, common water intake devices on the market include telescopic rod type water intake rods, electric water pumps, and simple water intake bottles. Among them, the use of the telescopic rod type water intake rod is easily limited by the water intake distance. When the water intake point cannot be approached, there is difficulty in water intake. In addition, the overall structure of the telescopic water intake rod is also relatively heavy, which will increase the work intensity of the water intake personnel. The electric water pumping device can quickly pump water with a longer suction distance. Although it ca...

Problems solved by technology

Among them, the use of the telescopic rod type water intake rod is easily limited by the distance of water intake. When the water intake point cannot be approached, it is difficult to obtain water. In addition, the overall structure of the telescopic water intake rod is also heavy, which will increase the work intensity of the water intake personnel.

The electric water pumping device can quickly pump water with a longer suction distance. Although it can reduce the burden on the water fetching personnel, it is inconvenient to carry and use because the device needs an additional power source.

There are also some water-taking devices with simple structures. Usually, the water-taking bottle is tied to a rope or a pole, and the water is thrown into the water with the opening upward to get water. Although the device is simple in structure and easy to operate, it is affected by the buoyancy and the gravity of the water-taking bottle. , it is difficult to keep the mouth of the bottle level, the effect of taking water is often not ideal, and it is also difficult to take water samples deeper below the liquid surface

[0003] To sum up, the existing water intake device with a simple structure is not easy to control the water intake process, and cannot realize the collection of water samples at deeper positions below the liquid surface; while the electric water pumping device has a complex structure, is not easy to carry, and is not flexible enough to meet some special scenarios. water demand for
