Problems solved by technology

At present, the tidal flat bottom is mainly sampled manually by hand. Not only is it inconvenient to ship, but also it is difficult to pour out the water in the sample, which is time-consuming and laborious. The influence of human factors is relatively large, and it is also dangerous; the current water sample collection device is more suitable. For the collection of water samples from rivers and lakes, the water inlet of the device is generally located at the bottom, and in the tidal flat environment, the process of lowering the water collection device will mix in disturbances such as sediment, animals and plants, which reduces the efficiency of water sample collection

Embodiment Construction

[0055] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0056] like Figure 1-3 As shown in the figure, the present invention provides a marine tidal flat environment collection system, including a sediment collection system and a water sample collection system. On the mud separator 1, after the mud separator 1 is inserted into the mudflat substrate to the required depth, lift the mud separator 1 slightly to leave a tight space for the opening of the mud bag 2. At this time, pull the mud bag 2 twice. End the mud bag with the drawstring 6 to complete the bagging and sealing of the mud sample, then lift the mud bag 2 out of the mud separator 1, and then put it into the water sample collection system. The water sa...

Abstract

The invention relates to an ocean mud flat environment sampling system and method, the system comprises a substrate collection system and a water sample collection system, the substrate collection system comprises a mud separation barrel and a mud collection bag, the mud collection bag is arranged in the mud separation barrel, the bottom of the mud collection bag is open, the top of the mud collection bag is closed, and the bottom opening of the mud collection bag is turned over outwards to wrap the outer side of the periphery of the bottom of the mud separation barrel; the water sample collection system comprises a mud separation barrel and a water collector, the water collector is arranged in the mud separation barrel and comprises a water collection barrel, more than one circle of water inlet holes are formed in the position, close to the bottom, of the side wall of the water collection barrel, the water collection barrel is sleeved with a closed ring, and the closed ring is located above the water inlet holes and can move downwards to block the water inlet holes. The method comprises the following steps: simultaneously placing a mud collection bag and a water collector in a mud separation barrel, and simultaneously collecting a substrate and a water sample by the water collector positioned above the mud collection bag, or independently placing the mud collection bag and the water collector in the mud separation barrel, and respectively collecting the substrate and the water sample. The device is ingenious and flexible in structural design, and a substrate and water sample collecting device controllable by a single person is achieved.

Description

technical field [0001] The invention relates to a marine tidal flat environment sampling system and method, belonging to the technical field of marine tidal flat sampling. Background technique [0002] Marine tidal flats are called "intertidal zones" in geomorphology. The ecology of marine tidal flats has important economic and environmental benefits. In recent years, tidal flat agriculture and fishery have brought environmental problems to the marine tidal flat areas that cannot be underestimated, resulting in a certain degree of pollution. The monitoring of microorganisms and various pollutants is the basis for studying the ecology of marine tidal flats, and the sampling of the tidal flat environment is a necessary link in the study of microbial communities and various pollutants in the tidal flat environment. [0003] The tidal flat environmental sampling is quite different from the conventional inland river and lake sampling. The sediment in the river and lake environmen...
