Embodiment 1

[0070] The use method of the above-mentioned polyvinyl alcohol-based sponge water sampling device of the present invention will be described in detail below.

[0071] Step 1: After the well cleaning is completed, open the air hole sealing covers on the sealing head 1 and sealing head 2, and fix the sling on the connecting part;

[0072] In the second step, place one end of the sealing head one downwards and one end of the sealing head two upwards, and pull the polyvinyl alcohol-based sponge water sampling device slowly into the groundwater monitoring well by pulling it with a sling;

[0073] The third step is to lower one end of the sealing head to the target water surface as a mark, wait for a certain period of time, and after the water body is completely filled with the polyvinyl alcohol-based sponge, take a water sample from the polyvinyl alcohol-based sponge with a traction rope Lift the device to the surface, and immediately install the first sealing head and the second s...

Embodiment 2

[0077] Such as Figure 4 As shown, the above-mentioned polyvinyl alcohol-based sponge water sampling device of the present invention is used in conjunction with the water pressure piston 13 and the water sample collection bottle 12. Preferably, the water pressure piston 13 is made of PE, PVC material or wood, and the length is greater than or equal to the length of the protective shell 2 of the device. When compressed, the diameter of the end that contacts the polyvinyl alcohol-based sponge is equal to or slightly smaller than the inner diameter of the protective shell.

[0078] Step 1: After the well cleaning is completed, open the air hole sealing covers on the sealing head 1 and sealing head 2, and fix the sling on the connecting part;

[0079] In the second step, place one end of the sealing head one downwards and one end of the sealing head two upwards, and pull the polyvinyl alcohol-based sponge water sampling device slowly into the groundwater monitoring well by pulling...

Embodiment 3

[0084] The above-mentioned polyvinyl alcohol-based sponge water sampling device is used in conjunction with a drone, and the start and stop of the electric miniature winch 11 is controlled by the remote control to control the lifting, landing and hovering of the device when taking water samples.

[0085] The first step is to open the air hole seal covers on the sealing head 1 and sealing head 2, fix the sling, and then fix the other end of the sling to the electric mini hoist connected to the drone;

[0086] The second step is to fly the drone to the predetermined location where water samples need to be taken, then lower the position of the drone, start the electric miniature winch remotely through the remote control of the drone, and slowly release the sling to make the polyethylene The alcohol-based sponge water sampling device slowly approaches the water surface of the destination;

[0087]The third step is to control the electric miniature winch, so that the polyvinyl alco...

Abstract

The invention discloses a polyvinyl alcohol-based sponge water sampling device, a use method of the device and an application thereof, and relates to the field of water sampling in hydrogeological survey and site environment survey. The device comprises a water taking component, a protective shell and a first sealing head. The protective shell is a hollow pipe body, the two ends of the hollow pipebody are open, and the first sealing head is fixed to one end of the hollow pipe body; the water taking component comprises a second sealing head and a polyvinyl alcohol-based sponge body fixedly connected to the second sealing head, the polyvinyl alcohol-based sponge body is located in the hollow pipe body, and the second sealing head is fixed to the other end of the hollow pipe body; and the second sealing head is provided with a vent hole capable of penetrating through the hollow pipe body and the outside, the vent hole extends outwards to form a section of hollow pipe, the end of the hollow pipe is provided with a sealing cover for sealing the hollow pipe, and the second sealing head is further provided with a connecting part. The device provided by the invention solves a technical problem of limited usage scenarios of a water sampling mode in the prior art, can realize remote water sampling, and saves manpower and material resources.

Description

technical field [0001] The present invention relates to the field of water sampling in hydrogeological survey and site environment investigation, in particular to a polyvinyl alcohol-based (PVA) sponge water sampling device, a method for using the device and its application, which can be used for sampling groundwater monitoring wells, and also It can be used for remote control of water sampling by drones on the surface of rivers, lakes and seas that humans cannot directly reach. Background technique [0002] At present, the country is paying more and more attention to environmental protection. Environmental investigation is the main means to understand the current situation of the environment. In environmental investigation work, water sampling from groundwater monitoring wells and sampling of natural water bodies are indispensable work links. At present, the Baylor tube is the most commonly used device for groundwater sampling. It mainly has the following limitations: [0...
