Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the present invention is further described:

[0014] like figure 1 and figure 2 As shown, the main body of the device includes four parts: a base 1 , a support system, a system of sampling tubes 4 and tube racks 5 , and a built-in fixing matrix 6 .

[0015] The base 1 is a cylinder with an open upper end, and a convex ring 8 is welded inside the middle height of the base 1 to carry the pipe frame 5; it is recommended that the base 1 be made of metal, and its recommended size is: the inner diameter of the base 1 is 50cm and a height of 23cm.

[0016] The support system is outside the base 1 and is composed of three vertical main rods 3 and a horizontal ring 2 welded together. The three vertical main rods 3 are distributed in an equilateral triangle and inserted into the water body soil to fix the base 1. Function, there are four screws 7 on the horizontal ring sleeve 2, which are used to adjust the relative position bet...

Abstract

The invention provides an in-situ time-phased sediment trap which is suitable for lakes, rivers and other non-turbulent flow water bodies and can realize long-term monitoring and in-situ time-phased trapping of sediments to prevent a microenvironment of the sediments at the bottom of water from being damaged. The device comprises four parts, namely a base, a support system, a sampling pipe, a pipe frame system and a built-in fixed matrix. The base is of a cylinder with an opening at the upper end, and a convex ring is arranged in the base for carrying the sampling pipe and the pipe frame system; the support system is formed by welding three vertical main rods and a transverse ring sleeve together, the three main rods are distributed like an equilateral triangle and are used for being inserted into soil at the bottom of the water for playing roles in fixing and supporting the base, and four screws are arranged on the ring sleeve and are used for regulating the relative positions between the base and the ring sleeve, so that the height of the base is further regulated; the sampling pipe is detachably matched with the pipe frame system, and the number and the size specification can be customized according to requirements; and the built-in fixed matrix of the sampling pipe can fix the sediments which flow into the pipe in the pipe to avoid re-suspension.

Description

technical field [0001] The invention belongs to the field of environmental ecology, and relates to an in-situ time-segmented sediment collection device, which is suitable for in-situ time-segmented sediment collection or long-term sediment deposition in non-turbulent water bodies such as lakes, streams, and rivers. observe. Background technique [0002] Different types of sediments are often formed in different areas of the same lake or river. Most of the deposits in the nearshore zone are coarse-grained pebbles, boulders and sandy soils, while those deposited in the farshore zone are fine-grained sandy soils and clayey soils. Lakes can become swamps if they become silted up, forming swampy deposits, including silt and plant humus. The study of the sedimentation rate and physical and chemical properties of sediments is an important means to reveal the geomorphology and nutrient cycle of lakes and rivers, and has been widely used in previous studies. When studying the phys...
