Embodiment 1

[0046] figure 1 It is a schematic structural diagram of the portable surface sediment sampling device in Example 1. The portable surface sediment sampling device includes: a base plate 1 , a left plate 2 , a right plate 3 , a push rod 4 , a positioning plate 5 , and a back plate 6 . Wherein, the left side plate 2 is fixedly connected with the left side of the base plate 1, the right side plate 3 is fixedly connected with the right side of the base plate 1, and the push rod 4 is hinged with the outer side of the base plate 1; The rear end of the back plate is fixedly connected, the left side of the back plate 6 is connected with the left side plate 2, and the right side of the back plate 6 is connected with the right side plate 3; the left side plate 2 and the right side plate 3 have N pairs of The installation groove 7, N is an integer greater than or equal to 1, the intervals between adjacent installation grooves on the left side plate 2 and the right side plate 3 are the sa...

Embodiment 2

[0057] Figure 7 It is a structural schematic diagram of the portable surface sediment sampling device in the second embodiment. In order to prevent the problem of inaccurate collection caused by the position change of the push rod relative to the bottom plate 1 when the portable surface sediment sampling device is used for collection, the outer sides of the ends of the left side plate 2 and the right side plate 3 connected to the back plate 6 are respectively symmetrical It is provided with at least one push rod clamping device 9 . The intervals between adjacent push rod clamping devices 9 are the same.

[0058] The front end of the bottom plate 1 is a wedge-shaped structure, and the angle of the wedge-shaped structure is θ. In order to make the acquisition angle better during acquisition, the left push rod 42 is fixed on the lowest position of the push rod clamping device 9 on the left side plate 2. The angle between the push rod 42 and the base plate 1 is also θ, and the ...

Embodiment 3

[0060] In order to prevent the part of the sampling device that does not need to collect surface sediment from entering too much sediment during the collection process, a shielding device is added in the third embodiment. Figure 8 It is a structural schematic diagram of the portable surface sediment sampling device in the third embodiment. The portable surface sediment sampling device also includes a shielding plate 10, the inner side of the side that is not connected to the bottom plate 1 and the back plate 6 on the left side plate 2 has a chute, and the right side plate 3 has no connection to the bottom plate 1 and the back plate 6. The inner side of the connected side has a chute, and the two sides of the shielding plate 10 are respectively arranged in the chute of the left side plate 2 and the chute of the right side plate 3 .

[0061] In each of the above-mentioned embodiments, the following features can also be included:

[0062] In order to make the sampling device wh...

Abstract

The invention discloses a portable surficial sediment sampling device with controllable sampling thickness and a sampling method thereof. The sampling device comprises a bottom plate (1), a left side plate (2), a right side plate (3), a push rod (4), locating plates (5) and a back plate (6), wherein the push rod (4) is articulated with the outer edge side of the bottom plate (1); the left side plate (2) and the right side plate (3) are provided with N pairs of mounting grooves each pair of which has equal distance with the bottom plate; intervals of the adjacent mounting grooves (7) of the left side plate(2) and the right side plate (3) are same; the locating plates (5) are arranged in the mounting grooves (7) in a manner of being parallel to the bottom plate (5). The left side plate and right side plate of the sampling device are provided with the mounting grooves different in position, and the sampling thickness is adjusted through setting the distances between the locating plates and the bottom plate, so that the sampling device is capable of sampling sediment different in thickness. The sampling device is adjustable in sampling thickness, accurate in sampling, convenient to operate, light in weight, detachable and convenient to carry.

Description

technical field [0001] The invention relates to a sample collection device, in particular to a portable surface sediment sampling device and a sampling method with controllable sampling thickness. Background technique [0002] Sediment is an important part of waters such as rivers, lakes, reservoirs, and oceans. It can exchange materials with the overlying water body through various channels. The migration and transformation of heavy metals, organic chlorine and other pollutants in sediments have great impact on aquatic organisms and The living environment of benthic animals plays an important role. The "health" of sediments is undoubtedly related to the health of aquatic ecosystems, and then affects humans through the food chain. Therefore, it is of great significance to collect and monitor sediment samples . [0003] At present, there are many types of sediment sampling devices developed at home and abroad, mainly including gravity samplers, piston samplers, connecting ro...
