Abstract

The invention discloses a water intake device. The water intake device comprises a casing, a water storage chamber, a lower valve and an upper valve, wherein a water inlet is formed in the bottom of the casing, and a water outlet is formed in the top; the water storage chamber is located between the water inlet and the water outlet, and comprises an upper partition and a lower partition which arein sealed connection with the inner wall of the casing respectively, a water inlet channel is formed in the lower partition, and a water outlet channel is formed in the upper partition; the lower valve is located at an outlet of the water inlet channel, the upper valve is located at an outlet of the water outlet channel, and the bottom of the upper valve is fixedly connected with the top of the lower valve through a connecting piece. When the water intake device is put downwards, water in non-sampling depth flushes open the lower valve through the water inlet and flows into the water storage chamber, then flushes open the upper valve and is discharged from the water outlet, and only water samples in the current depth are retained in the water storage chamber. When the water intake device is lifted up, the lower valve covers the water inlet channel, the upper valve covers the water outlet channel, and water in the non-sampling depth cannot flow into the water intake device in the lifting process. The water intake device is simple in structure and convenient to operate, and can ensure quality of the water samples.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a water fetcher. Background technique [0002] Water conservancy work often needs to take samples of groundwater systems at a certain depth. At present, there are various methods for sampling groundwater in survey holes, such as pumping water samples, fixing water bottles on wooden sticks for sampling, and using weights under the water bottles and then lowering samples through ropes. These are low-cost sampling methods. The device cannot guarantee that it will not pour water at a non-sampling depth before reaching the predetermined depth, resulting in the sample taken out not from the water body at the predetermined depth, or a mixed water sample at other depths and sampling depths. However, other advanced precision sampling equipment with complex structure has the problems of complex structure, high cost, difficult operation and high energy consumption, which greatly increases t...
