Embodiment
[0025] like figure 1 , figure 2 , image 3 and Figure 4 The shown indoor artificial wetland water sample and substrate sample collector of the present invention is composed of a sampling tube main body 100, a baffle plate 200 and a sample hooking device 300;
[0026] The main body of the sampling tube is composed of an upper part 110 and a lower part 120 connected by threads 130. The upper part is a tube body with transparent ends, and a handle 111 is arranged on the outside, and the lower part is a tube body with an open upper end. A sampling hole 121 is arranged on the body, and a rubber slot 1211 is arranged on the inner surface of the sampling hole;
[0027] The baffle plate 200 is composed of an inserting plate 210, a handle 220 and a connecting rod 230, and the inserting plate is used to be inserted into the rubber slot;
[0028] The sample filler hooking device 300 is composed of a handle 310 and a sampling hook 320 .
[0029] A scale (not shown in the figure) is...

Abstract
The invention discloses an indoor subsurface-flow constructed wetland water sample and matrix sample collector which consists of a sampling tube main body, a baffle and a sample hooking device. A sampling hole is formed in the sampling tube main body; a rubber slot is formed in the inner surface of the sampling hole; the baffle consists of an insertion plate, a grab handle and a connecting rod; the insertion plate is used for being inserted into the rubber slot; a sample filler hooking device consists of the grab handle and a sampling hook. A sampling tube is conveniently inserted into a wetland for sampling, and drop and loss of the sample are effectively avoided; scales are marked on the wall of the sampling tube, so that the sampling depth is conveniently and accurately mastered; the handle is arranged at the upper end of the sampling tube, so that an operator conveniently applies force; the baffle and the slot are arranged, and a rubber sealing device is arranged in the slot, so that the interior and exterior of the sampling tube are completely isolated when the baffle is inserted, and when the baffle is pulled out, the sample can enter the tube through the sampling hole; outside filler can be shifted into the sampling tube by inserting the sampling hook from the sampling tube into the sampling hole, so that sampling is facilitated; the sampler is convenient to use and easy to operate and is completely suitable for an indoor constructed wetland sampling environment.
Description
technical field [0001] The invention relates to an indoor artificial subsurface flow wetland water sample and substrate sample collector. Background technique [0002] As an efficient water purification facility, artificial subsurface wetlands can effectively control the deterioration of aquaculture water quality. The recirculating aquaculture system based on artificial subsurface wetlands is a new trend in the development of aquaculture models in the future. Therefore, it is an important topic in the field of ecological aquaculture to study the water purification mechanism of constructed wetlands and further study its strengthening technology. [0003] In the research, the indoor artificial subsurface wetland is usually constructed as the research object to increase the stability and convenience of the system, and the collection of indoor artificial wetland water samples and matrix samples is an essential link in the research. However, because the constructed indoor compos...
