Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic sampling device and sampling method for river and lake bottom mud, so as to solve the problem in the prior art that the traditional method for taking samples from the lake is not only time-consuming and laborious, but also has certain dangers in places where the water is deep and far away from the shore. In addition, there are still technical problems such as inaccurate sampling depth and mixing of sediment at different depths.

Embodiment 1

[0031] like Figure 1-4 As shown in a automatic sampling device sediment rivers, the hull includes a controller 1, is provided on the hull 2, a first water pump 3, a second pump, hydraulic platform 15 and sample 7, the first pump out 3 communicates with the outlet of the tee first interface communicates with the inlet of the second interface of the second tee of the pump, the second pump outlet in communication with the drain pipe 5, and the third interface tee inlet 6 the upper end of the communication, a hose inlet pipe, which satisfies the length of the sampler 7 drop height.

[0032] The sampler 7 in the vertical direction by a plurality of sampling tube splicing composition, such as figure 2 , Each sample is provided with a cylinder liner 10, a lower portion of the side wall of the liner defines a sampling opening 12, the upper end of each liner is provided with a communicating tube 9, the lower end of all of the communication pipe communicating with the inlet pipe.

Embodiment 2

[0041] Based on the above-mentioned rivers sediment sampling automatic sampling device, comprising the steps of:

[0042] Step 1, starting ship hull to move to the sampling area selected sampling cylinder liner according to the amount corresponding to the desired sample volume, and assembled into the selected sampling tube sampler, and connected to the hydraulic platform on the hull;

[0043] Step 2, the input information required by the sampling operation of the man-machine interface of the operation screen;

[0044] Step 3, opening hydraulic platform, hydraulic platform is moved downward along the drive rail sampler; simultaneously open the first water pump, water is fed through the inlet pipe liner then removed from the sampling port, to prevent sludge sampler during descent from affect the sampling results of the sampling port into the interior; when the controller detects a first pressure when the data collected by the sensor increases abruptly, and thereafter the data unchan...

Abstract

The invention discloses an automatic sampling device and sampling method for river and lake bottom mud, which comprises a hull, a controller arranged on the hull, a first water pump, a second water pump, a hydraulic platform and a sampler. The sampler consists of a plurality of sampling cylinders along a vertical Direction splicing composition, each sampling cylinder is provided with a liner, the lower part of the side wall of the liner is provided with a sampling port, the upper end of each liner is provided with a connecting pipe, and all the connecting pipes are connected with the lower end of the water inlet pipe; the hull On the upper installation track, the upper end of the sampler is connected to the hydraulic platform; the bottom of the sampler is provided with a first pressure sensor; the first water pump, the second water pump, the hydraulic platform, the first pressure sensor, the first flowmeter and the second flowmeter are all It is electrically connected with the controller, and the controller is connected with a man-machine operation screen. The device can automatically collect sediment samples from rivers and lakes, and the sampling volume and depth can be precisely controlled. The sampling time and location can be recorded synchronously, with simple operation, labor saving and cost saving.

Description

Technical field [0001] The present invention belongs to the technical field of environmental engineering RESOURCES sampling device, more particularly to an automatic sampling device and rivers sediment sampling methods. Background technique [0002] In order to understand the hydrological conditions, as well as some environmental assessment or scientific purposes, it is necessary to sample the different local rivers and lakes. Wherein for deeper water, sediment sampling difficult place away from the shore. Sampling the lake by a conventional method not only time consuming, but also has a certain degree of risk. But there is a problem imprecise sampling depth, sediment and mixing different depths. Inventive content [0003] Object of the present invention is to provide an apparatus and sampling methods rivers sediment autosampler, to solve the prior art deep water, away from the shore where the conventional method of sampling the lake not only time consuming, but also has a certa...
