Description

Technical Field

[0001] The utility model relates to the field of benthic organism sampling, in particular to a benthic organism sampler. Background Art

[0002] Benthic organisms mainly refer to animals and plants that live on the bottom of rivers, lakes and seas. The biggest feature of benthic organisms is that they live on the mud bottom. Therefore, when sampling them, it is generally necessary to place a triangular trawl on the bottom of rivers, lakes and seas, and then tow it through the suspended hull to sample the mud and benthic organisms on the bottom of the river, lake and sea.

[0003] The Chinese public patent number is: CN220422825U, a water ecological sediment sampling tool. This patent is provided with a counterweight block to prevent the net mouth from tilting up during towing, so as to better collect benthic animals in the sediment and improve the efficiency and accuracy of collecting benthic animals. However, although the device can fix the net, the tail end of the net cannot be fixed. Therefore, when the hull is towing, the net fixed by the device is likely to shift during the towing process, and the folded net will prevent the soil from entering the interior of the net well, resulting in insufficient sampling and general sampling efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a benthic organism sampler to solve the above-mentioned shortcomings in the technology.

[0005] In order to achieve the above object, the utility model provides the following technical solution: a benthic organism sampler, comprising:

[0006] A triangular shovel block, wherein the three ends of the triangular shovel block penetrate and are fixedly connected with a grid body, the top of the grid body is fixedly connected with a first fixing ring, the inner wall of the first fixing ring is fixedly connected with a tail sealing threaded tube, the top of the tail sealing threaded tube is threadedly connected with a sealer, the top of the sealer is fixedly connected with a hook, the bottom of the grid body is fixedly connected with a second fixing ring, the interior of the second fixing ring is movably sleeved with a fixing steel rope, and the end of the fixing steel rope away from the second fixing ring is movably sleeved with a suspension ring;

[0007] A net garment, wherein the side of the net garment is fixedly connected with a binding belt, and the net garment is movably bound to the inside of the net frame body through the binding belt.

[0008] Preferably, fixing holes are provided on the side surface of the bottom end of the tail sealing threaded tube and the side surface of the top end of the triangular shovel block.

[0009] Preferably, handles are fixedly connected to both sides of the triangular shovel block.

[0010] Preferably, both ends of the fixed steel rope are fixedly sleeved with protective rubber sleeves.

[0011] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0012] By providing a tail sealing threaded tube, the weight of the tail is increased to maintain the stability of the entire device, and it is also beneficial to fix the net, thereby preventing the net from deviating during sampling operations and causing the net to fold, greatly improving the sampling efficiency of benthic organisms. In addition, since the triangular shovel block is thinner on both sides and thicker on the third side, the thicker side has a heavier weight, so when the triangular shovel block is dragged, it can prevent the device from warping and rolling during the dragging process, further improving the stability during sampling.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The utility model provides Figure 1-Figure 4 A benthic organism sampler is shown, comprising:

[0022] A triangular shovel block 7, the three ends of which penetrate and are fixedly connected with a grid body 5, the top of the grid body 5 is fixedly connected with a first fixing ring 4, the inner wall of the first fixing ring 4 is fixedly connected with a tail sealing threaded tube 13, the top of the tail sealing threaded tube 13 is threadedly connected with a sealer 3, the top of the sealer 3 is fixedly connected with a hook 2, the bottom of the grid body 5 is fixedly connected with a second fixing ring 9, the inside of the second fixing ring 9 is movably sleeved with a fixing steel rope 10, and the end of the fixing steel rope 10 away from the second fixing ring 9 is movably sleeved with a suspension ring 12;

[0023] The net 1 has a side fixedly connected with a strap 6, and the net 1 is movably tied to the inside of the grid body 5 through the strap 6, so that the net 1 can be better fixed, thereby greatly improving the sampling efficiency.

[0024] Furthermore, fixing holes 14 are provided on the side surface of the bottom end of the tail sealing threaded tube 13 and the side surface of the top end of the triangular shovel block 7, so as to further increase the stability of the net 1 during sampling.

[0025] Furthermore, handles 8 are fixedly connected to both sides of the triangular shovel block 7 to facilitate the lifting operation of the device.

[0026] Furthermore, both ends of the fixed steel rope 10 are fixedly sleeved with protective rubber sleeves 11, which can fix the steel wire and prevent the steel wire from getting caught on the hands.

[0027] Through the above technical solution:

[0028] When in use, the net 1 is first bound to the inside of the grid body 5 by the binding strap 6, and then the tail end of the net 1 is extended into the inside of the tail sealing threaded tube 13. At this time, the tail end and the opening of the net 1 can be fixed to the inner wall of the tail sealing threaded tube 13 and the inner wall of the triangular shovel block 7 respectively by a rope passing through the fixing hole 14, so as to increase the stability of the net 1 during collection, and then the sealer 3 is rotated and fixed to the top of the tail sealing threaded tube 13 by the hook 2, and the triangular shovel block 7 is designed to be thinner on both sides and thicker on the third side. The thicker side has a heavier weight, so that when the triangular shovel block 7 is dragged, it can prevent the phenomenon of upward warping and rolling during the dragging process. The thinner two sides are fixedly connected with handles 8, which is convenient for carrying the device. When the net 1 is assembled, the hull can be suspended by the hanging ring 12 to carry out benthic biological sampling operations. When the sampling is completed, the samples at the deeper end of the net 1 can be directly exported through the tail sealing threaded tube 13 by rotating to open the sealer 3.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
