Description

Beller tube for deepwater sampling

Technical Field

The utility model belongs to the technical field of the technique of bailer tube and specifically relates to a bailer tube for deep water sample is related to.

Background

Groundwater, is water stored in the voids of the formation, including rock pores, fractures and vugs, below the gas-filled zone. Groundwater is an important component of water resources, however, in recent years, under the action of various pollution sources, shallow groundwater in China is seriously polluted and the pollution speed is high. Groundwater pollution mainly refers to the phenomenon that quality of groundwater is reduced due to changes in chemical components, physical properties and biological characteristics of groundwater caused by human activities. Because the stratum under the surface of the earth is complex and the groundwater flows very slowly, the groundwater pollution has the characteristics of slow process, difficult discovery and difficult treatment. Once the ground water is polluted, even if the pollution source is completely eliminated, the water quality can be recovered for more than ten years or even several decades.

the prior chinese patent with granted publication No. CN207336126U discloses an improved beller tube, which is mainly used for measuring water level in wells, drill holes and water level tubes, and is particularly suitable for environment detection, environment investigation and observation of underground water level in hydropower engineering or manual inspection of dam body infiltration lines of earth and stone dams. The bailer tube comprises a main body, a lifting rope and a check ball, wherein the main body of the bailer tube is formed by sequentially connecting one or more hollow tubes, the lifting rope is connected in the hollow tubes through a lifting rope connecting piece, a valve seat matched with the check ball is arranged in the lower end of each hollow tube, a through hole is formed in the valve seat, the check ball is movably connected to the through hole on the valve seat, and an ejection rod is further arranged on the lifting rope connecting piece.

The above prior art solutions have the following drawbacks: the water inlet is seted up to current bailer pipe including the body, body top seal, body bottom, and the water inlet department in the body sets up the check ball, and when the bailer pipe got into the water, the check ball just begins to intake in will being jack-up the bailer pipe, leads to the unable water sample of getting the deep water in underground of bailer pipe, and this problem is waited for to solve urgently.

SUMMERY OF THE UTILITY MODEL
