Description

Technical Field

[0001] The utility model relates to the technical field of biological collection, in particular to a benthic animal collector. Background Art

[0002] A benthic zoopheresis collector is a specialized device used to obtain samples of organisms at the bottom of water bodies (such as insects, crustaceans, mollusks, etc.). It is widely used in ecology, environmental monitoring, biodiversity assessment and other fields. This can be traced back to the increasing demand for research on aquatic ecosystems, especially in water resource management, pollution monitoring and biological protection. With the increasing attention paid to water pollution issues and the development of ecological health assessment methods, benthic zoopheresis has become a research focus due to its importance in aquatic ecosystems. Benthic zoopheresis is usually at a lower level in the food chain, and their sensitivity to environmental changes makes their population structure and biodiversity an indicator of water health. In order to accurately assess the species and quantity of benthic zoopheresis, scientists have developed a variety of collection techniques. Early collection methods mainly relied on manual sampling, which was inefficient and prone to sample loss.

[0003] A soper net is a common net used to capture benthic organisms. It can effectively capture animals on the bottom of the water, such as insects, crabs and other organisms. In actual use, this net shows good efficiency in capturing underwater organisms. However, when some organisms hide or burrow into the mud, the soper net's capture efficiency decreases. Due to the limitations of its mesh and structure, the soper net cannot penetrate deep enough into the mud to extract those organisms hiding in the sediment, which will reduce the capture rate of benthic organisms, thereby affecting researchers' comprehensive assessment of the biodiversity and ecological status of the water body.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 The utility model provides a technical solution: a benthic animal collector, including a Soper net 1, a support frame 2 is provided at the end of the Soper net 1, both sides of the support frame 2 are rotatably connected with triangular folding plates 3, the bottoms of the two triangular folding plates 3 are rotatably connected with support plates 4, the ends of the two support plates 4 are detachably connected, the bottom of the support frame 2 is fixedly connected with a connecting rod 5, a shovel plate 6 is provided at the bottom of the Soper net 1, the shovel plate 6 is detachably connected to the connecting rod 5, an operating rod 7 is provided on the shovel plate 6, and the top of the support frame 2 is fixedly connected with a fixing plate 8 for easy removal.

[0025] When in use, first unfold the two triangular folding plates 3, then unfold the support plate 4, and connect the ends of the two support plates 4 together, and then connect the shovel plate 6 to the end of the connecting rod 5. When collecting benthic organisms, hold the fixed plate 8 to place the collector in a suitable position, then hold the operating lever 7 to operate and rotate, drive the shovel plate 6 to rotate and scoop up the soil and the benthic organisms in the soil. At the same time, the support plate 4 can cut off the excess soil on the shovel plate 6, and then pour the soil on the shovel plate 6 into the Sober net 1, thereby completing the sampling of benthic organisms in the soil. After the collection is completed, remove the shovel plate 6 from the end of the connecting rod 5, and then fold the support plate 4 and the triangular folding plate 3, which is easy to carry and can be quickly unfolded when in use, so as to more efficiently collect benthic organisms in the soil.

[0026] Furthermore, both ends of the connecting rod 5 are fixedly connected with screw rods 9 , and the external threads of the screw rods 9 are connected with fixing nuts 10 .

[0027] See also Figure 4 、 Figure 5The connection method of the screw rod 9 and the fixing nut 10 can ensure that the connecting rod 5 remains firm during use, reducing loosening caused by operation or water flow, thereby improving the overall stability of the collector. This threaded connection design makes it easier to disassemble and replace the connecting rod 5 and the shovel plate 6.

[0028] Furthermore, a plurality of filter holes 11 are evenly arranged on the shovel plate 6 .

[0029] See also Figure 2 The filter hole 11 can be set to discharge water during the collection process, reduce the resistance of the shovel plate 6 when moving, and enable the shovel plate 6 to work and collect more efficiently. At the same time, it can also effectively discharge excess soil and sediment, avoiding excessive debris from affecting the purity of the sample.

[0030] Furthermore, a movable plate 12 is slidably connected to the interior of the shovel plate 6 , and holes are formed on the movable plate 12 at positions corresponding to the filter holes 11 .

[0031] See also Figure 2 、 Figure 6 When in use, the position of the movable plate 12 can be moved. When the filter hole 11 coincides with the hole position on the movable plate 12, the shovel plate 6 can filter the water. When the filter hole 11 and the hole position on the movable plate 12 are staggered, the shovel plate 6 can shovel up some small benthic organisms. It can be selected according to actual conditions.

[0032] Furthermore, a fixing screw 13 is threadedly connected to the movable plate 12 , and the end of the fixing screw 13 abuts against the outer wall of the shovel plate 6 .

[0033] See also Figure 2 、 Figure 6 After moving the movable plate 12 to a suitable position, tighten the fixing screw 13 to fix the movable plate 12 at a certain position of the shovel plate 6.

[0034] Furthermore, the shovel plate 6 is made of metal.

[0035] See also Figure 2 The metal surface is usually smooth, easy to clean and maintain, can effectively remove attached dirt and biological residues, has high strength and wear resistance, can withstand greater pressure and impact, and extend the service life of the shovel plate 6.

[0036] Furthermore, the end of the shovel plate 6 is fixedly connected to an extension rod 14, and the end of the extension rod 14 is slidably connected to the inside of the operating rod 7. The operating rod 7 is threadedly connected to a fixing screw 2 15, and the end of the fixing screw 2 15 abuts against the outer wall of the extension rod 14.

[0037] See also Figure 2 、 Figure 3When in use, the operating rod 7 slides outside the extension rod 14. After adjusting to the appropriate length, tighten the fixing screw 15 to fix the length of the operating rod 7 and the extension rod 14. This makes adjustment more convenient and also makes it easier for personnel to hold the operating rod 7 for operation.

[0038] Furthermore, a handle bar 16 is detachably connected to the top of the support frame 2 .

[0039] See also Figure 1 The setting of the handheld rod 16 allows the operator to easily control and manipulate the collector, improves the flexibility and comfort of operation, and can enhance the stability of the collector during use, ensuring that it is not easy to tilt or move during underwater operation.

[0040] Working principle: When using the benthic animal collector, first unfold the two triangular folding plates 3, then unfold the support plate 4, and connect the ends of the two support plates 4 together, then align the holes on both sides of the shovel plate 6 with the ends of the screw rod 9 and snap them in, then tighten the fixing nut 10, connect the shovel plate 6 to the connecting rod 5, then connect the hand-held rod 16 to the top of the support frame 2, and then slide the operating rod 7 outside the extension rod 14. After adjusting to the appropriate length, tighten the fixing screw 2 15 to fix the length of the operating rod 7 and the extension rod 14, so that the operating rod 7 is in a convenient position. The filter 11 is placed in a hand-held position, and the position of the movable plate 12 is moved so that the filter hole 11 coincides with or intersects with the hole position on the movable plate 12. After completion, tighten the fixing screw 13 to fix the movable plate 12 at a certain position of the shovel plate 6. Then the Sober net 1 and the shovel plate 6 are placed in the water to collect benthic organisms. The end of the hand-held operating lever 7 is operated and rotated to drive the shovel plate 6 to rotate and shovel up the soil and the benthic organisms in the soil. At the same time, the support plate 4 can cut off the excess soil on the shovel plate 6, and then pour the soil on the shovel plate 6 into the Sober net 1, thereby completing the sampling of benthic organisms in the soil.
