Problems solved by technology

[0004] The existing field sampling devices designed for flowing water bodies such as springs and underground rivers are expensive, and do not consider the fluidity of water bodies and the convenience of sampling devices, so they are not suitable for popularization and promotion; at the same time, the time of groundwater runoff is not considered in the sampling process

Embodiment 1

[0058] Embodiment 1: Karst underground river water sample sampling device

[0059] Such as figure 1 As shown, the karst underground river water sample sampling device of the present invention includes a water reservoir 16 and a support rod 17, wherein:

[0060] The water storage 16 is in the shape of a cylinder as a whole, and includes a water inlet bin 2 and a water storage bin 6 arranged up and down and communicated with each other. The water inlet bin 2 has a water inlet for water flow, and the water inlet has two vertical On the inner wall of the water inlet bin 2, a longitudinal slot 11 is respectively provided near the two vertical sides of the water inlet, and the two longitudinal slots 11 are provided with adjustable controls for controlling whether the water flow can enter the water inlet bin 2. The water inlet baffle 10 is provided with a scale 9 on the adjustable water inlet baffle 10, and the water inlet is also provided with a protective net 12 for intercepting l...

Embodiment 2

[0063] Embodiment 2: the method for collecting karst underground river water sample by adopting karst underground river water sample sampling device

[0064] use figure 1 The method for collecting karst underground river water samples by the device comprises the following steps:

[0065] 1) Determine the tracer delivery point, receiving point and tracer delivery type:

[0066] After selecting the underground river to be sampled, determine the tracer delivery point and receiving point according to the hydrogeological conditions of the underground river and sampling purpose; then determine the type of tracer delivery based on the social and environmental conditions along the underground river;

[0067] 2) Calculate the amount of tracer delivery:

[0068] 2.1) Use a flow meter to measure the flow velocity V at the trace receiving point farthest from the delivery point f and flow q f , to estimate the expected arrival time T of the tracer in the longest tracer segment f , acc...

Abstract

The invention discloses a karst underground river water sample sampling device and a sampling method. The sampling device includes a water storage device and a supporting rod; the water storage device includes a water inlet cabin and a water storage cabin which are in up and down arrangement and mutual communication; the water inlet cabin has a water inlet, and the water inlet is provided with adjustable water inlet baffle plates and a protective screening; the positions, close to the two vertical sides of the water inlet, on the inner wall of the water inlet cabin are respectively provided with longitudinal inserting grooves; the adjustable water inlet baffle plates are interspersed in the two longitudinal inserting grooves; the top of the water inlet cabin is provided with a protective cover; the water storage cabin has a drainage outlet, and the outer circumferential wall of the water storage device is provided with fixing sleeves; the supporting rod consists of a connecting rod and a rod head; the connecting rod is provided with more than one through holes passing through the lateral width of the connecting rod; and the relative fixing of the supporting rod and the water storage device can be realized through a screw thread pair when the supporting rod is inserted into the fixing sleeves on the outer circumferential wall of the water storage device. The device is low in cost and has various functions of convenient carrying, current limiting, depth keeping and multiple measurement.

Description

technical field [0001] The invention relates to a water sample collection device and a sampling method, in particular to a karst underground river water sample sampling device and a sampling method. Background technique [0002] Water sample collection is continuous or intermittent sampling of boreholes, wells, springs, underground rivers, surface rivers and other water bodies through specific instruments and methods. At present, there are fixed-depth and real-time sampling devices and sampling methods for water sample collection of water point types such as boreholes and civilian wells. In addition to fixed-depth and real-time sampling devices and methods for surface water sample collection, multi-directional , Mixed sampling technique. Existing sampling devices and methods satisfy the sample collection of relatively static water bodies such as boreholes and civilian wells to a certain extent, and also meet the sample collection of flowing water bodies such as springs, und...
