Problems solved by technology

[0003] However, the existing sampling and pumping devices are inconvenient to set the distance from the bottom to the upper water layer to sample different water layers, resulting in single sampling water and large data errors. When sampling at multiple points, different locations are one by one Sampling requires repeated operations each time, which is cumbersome to operate and takes a long time to sample

Embodiment approach

[0050] Another technical solution proposed by the present invention: providing a method for implementing a sampling and pumping device with a water stop structure for hydrogeological drilling, comprising the following steps:

[0051] Step 1: by rotating the counterweight 432, determine the distance from the bottom of the counterweight 432 to the lower end surface of the connecting member 42 by rotating the number of turns of the screw thread, and this distance is the distance between the pumping and sampling component 5 and the water bottom;

[0052] Step 2: Put the extracting counterweight part 4 and the water sampling part 5 into the sampled water. When the connecting lead 42 sinks under the gravity of the counterweight 432 as a whole, the water sampling part 5 is sampling Under the action of the buoyancy of the storehouse, the extension pipe 511 is driven to rotate, and then the three pumping and sampling components 5 are unfolded, so that three underwater points can be samp...

Abstract

The invention discloses a sampling and water pumping device with a water stop structure for hydrogeological drilling and a method, relates to the technical field of hydrogeological equipment, and aims to solve the technical problems that the sampling and water pumping device is inconvenient to set the distance from the bottom to an upper water layer to sample different water layers and sample different positions one by one, the operation is troublesome, and the sampling time is long. The lower end of an upper connecting flange is provided with an extraction balance weight component, the lower end of the extraction balance weight component is provided with three water pumping and sampling components, the number of the water pumping and sampling components is three, the lower end of the middle of a connecting conduction piece is provided with a height adjusting assembly in a threaded mode, and the upper end of the height adjusting assembly is in threaded connection with the inner side of an extraction connecting assembly; the water pumping and sampling assembly is arranged at the lower end of the extending and folding assembly, the height can be limited, the water pumping and sampling assembly serves as a balance weight, the water bottom can be sampled, three points underwater can be sampled at the same time, and one-time operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of hydrogeological equipment, in particular to a sampling and pumping device with a water stop structure and a method for hydrogeological drilling. Background technique [0002] Hydrogeology, a branch of geology, refers to the various changes and movements of groundwater in nature. Hydrogeology is the science that studies groundwater. It mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational use, and the adverse effects of groundwater on engineering construction and mining and its prevention and control. With the development of science and the needs of production and construction, hydrogeology is divided into sub-disciplines such as regional hydrogeology, groundwater dynamics, hydrogeochemistry, water supply hydrogeology, ore deposit hydrogeology, and soil improvement hydrogeology. In recent yea...
