Description

Technical Field

[0001] The utility model belongs to the technical field of sampling tools, and in particular relates to a benthic animal collection device. Background Art

[0002] Benthic animals refer to aquatic animals that spend all or most of their life cycle at the bottom of a body of water. These animals, mostly invertebrates, form a vast and complex ecological group, encompassing species and lifestyles far more complex than those of zooplankton. Most benthic animals inhabit the bottom mud for extended periods, exhibiting strong regional distribution and limited migration. Therefore, accurate collection of benthic animals is crucial in benthic research.

[0003] At present, when collecting benthic animals, sampling tools such as mud samplers, scoop nets, kick nets, and so on are mainly used. There are also some benthic animal collection devices on the current market. For example, the invention application with publication number CN 117958223 A discloses a convenient collection and screening mangrove benthic animal sampler, including a sampling bucket, at least one movable cover, at least one handle and at least one connecting piece; the at least one movable cover is configured to be detachably connected to the sampling bucket; at least one screening hole is provided on the at least one movable cover; the at least one handle is configured to be detachably connected to the sampling bucket through the at least one connecting piece; the sampling bucket is arranged in an arc shape, and the sampling bucket is provided with at least one arc-shaped blade claw; the convenient collection and screening mangrove benthic animal sampler combines benthic animal collection with a primary screening and washing device, which is conducive to reducing the complexity of the tool and improving the efficiency of tool use. It adopts a detachable structure, and any damaged parts can be replaced with spare parts to avoid the situation where the entire device cannot be used due to damage to some parts. It is easy to carry and easy to operate. However, this collection device still has certain disadvantages: First, the sampling bucket structure is relatively simple, and the overall structure has limited applicable scenarios; second, the arc-shaped blade claw structure cannot fit different sampling scenarios; third, pushing or pulling the sampling bucket to squeeze the sediment will cause a large number of benthic animals to escape due to the open sampling bucket mouth; fourth, the overall structure is relatively bulky, which increases the risk of operation.

The platform plate is connected to the ball head through the ball rod. A second threaded column is provided at the top of the platform plate, and a second threaded hole corresponding to the second threaded column is provided at the tail end of the first short rod 2, so that the first short rod 2 and the universal joint 5 can be detachably connected by a threaded connection.

[0029] like Figure 1 、 Figure 3 and Figure 4 As shown, the network port assembly 3 is connected to the first short rod 2. The network port assembly 3 includes a network port ring 31, an intermediate rod 32, and a spring 33. The network port ring 31 is made of a coiled steel wire rope. The ends of the intermediate rod 32 are connected to the network port ring 31. The tail end of the intermediate rod 32 is provided with a third threaded column, and the top end of the first short rod 2 is provided with a third threaded hole corresponding to the third threaded column, so that the intermediate rod 32 and the first short rod 2 are detachably connected via a threaded connection. Two springs 33 are symmetrically arranged on either side of the intermediate rod 32.
