A quantitative sampling device for intertidal zone benthic animals

Abstract

This invention belongs to the field of benthic animal sampling devices, specifically a quantitative sampling device for intertidal benthic animals, comprising a sampling frame body and a sampling shovel. The sampling shovel is slidably connected to the sampling frame body via a slide rail. The sampling frame body includes a semi-circular handle, a frame, and a baffle. The sampling frame body can quantitatively determine the sampling range and depth. The sampling shovel, through the slide rail, cuts the bottom sediment at a fixed depth from the bottom of the sampling frame body, preventing sediment spillage and completing the quantitative collection of benthic animals from the sediment. This invention has a simple structure, prevents sample spillage during sampling, and can efficiently and quantitatively collect benthic animals from intertidal sediment.

Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a quantitative sampling device for intertidal benthic animals. Background Technology

[0002] Intertidal benthic animals refer to the various organisms that live among the mud, sand, and rocks in the intertidal zone, adapted to the constantly changing intertidal habitat with the ebb and flow of the tides. These organisms include various small crabs, shellfish, and other inconspicuous creatures, collectively known as "benthic organisms." They not only provide abundant food for birds that roam this area but also play a vital role in the complex marine-terrestrial ecosystem of the intertidal zone. Physical processes such as water depth, salinity, near-bottom current velocity, waves, suspended sediment concentration, sediment erosion, transport, and deposition all influence the distribution of benthic organisms and the structure of the intertidal community.

[0003] Traditional benthic animal sampling devices typically consist of a sampling frame and a flat-headed shovel. While the sampling frame can define the sampling range, it cannot effectively collect samples at a fixed depth. The flat-headed shovel, on the other hand, cannot effectively define the sampling range, and samples are scattered when digging for benthic animals in the sediment. Neither method can effectively and quantitatively collect fixed sediment and benthic animal samples, resulting in inaccurate benthic animal sampling. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative sampling device for intertidal benthic animals, which can meet the requirements for quantitative collection of benthic animals in intertidal mud and sand, solve the problem of quantitative sampling, and prevent the spillage of bottom samples during the sampling process.

[0005] The aforementioned quantitative sampling device for intertidal benthic animals includes a sampling frame body and a sampling shovel; the sampling shovel is connected to the sampling frame body via a slide rail; the sampling frame body consists of a semi-circular handle, a frame, and a baffle; the semi-circular handle is welded to the top of the frame; the sides and rear of the frame are wrapped by baffles; and a pressing plate is provided on the top of the sampling shovel.

[0006] Preferably, the semi-circular handles are provided in pairs and are respectively welded to the top of both sides of the frame for pressing down and lifting the sampling frame body.

[0007] Preferably, the semi-circular handle is made of stainless steel and covered with a rubber sleeve.

[0008] Preferably, the upper part of the frame is square with a side length of 25cm.

[0009] Preferably, the two corners at the bottom of the baffle are rounded arcs, which facilitates the sampling shovel cutting into the bottom of the sampling frame body from the side.

[0010] Preferably, the sampling shovel is rectangular, with a width of 25cm and a length of 55cm.

[0011] Preferably, the sampling shovel is divided into a pressing plate, a rigid stainless steel plate, and a flexible stainless steel plate from top to bottom. The bottom of the sampling shovel is made of flexible stainless steel, which is beneficial for the sampling shovel to cut into the bottom of the sampling frame body from the side to collect samples.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a sampling framework, sampling of intertidal benthic animals within a defined range can be achieved.

[0014] The sampling shovel is connected to the main body of the sampling frame via a slide, allowing the shovel to cut into the main body of the sampling frame from the side and extract the bottom mud at a fixed depth, preventing the mud from spilling and completing the quantitative collection of benthic animals in the mud.

[0015] By making the bottom of the sampling shovel flexible stainless steel and combining it with two smooth arc corners under the baffle, the sampling shovel can cut into the bottom of the sampling frame from the side to collect samples, thus fulfilling the requirement of quantitative sampling.
