Description

Technical Field

[0001] This utility model relates to the field of sampling technology for benthic animals in lakes, and in particular to a sampling device for detecting benthic animals in lakes. Background Technology

[0002] Sampling methods for detecting benthic animals in lakes mainly include tools such as the Peterson sampler, Sober net, trawl, and sieve. The Peterson sampler is suitable for collecting samples from soft bottom substrates such as mud and silt, with a sampling area of ​​1 / 16 square meter or 1 / 40 square meter per sample. It is suitable for both qualitative and quantitative sampling. The selection of sampling points and sampling frequency is also very important. Sampling points are usually set up in different areas of the lake, such as nearshore areas and deep water areas, with multiple sampling points in each area. The sampling frequency depends on the needs of the monitoring plan, generally once or multiple times a year. Benthic animals mainly include annelids, mollusks, and arthropods. These animals play an important role in the lake ecosystem, participating in material cycling and energy flow, and are very sensitive to environmental changes. Therefore, monitoring their species and abundance can assess the ecological environment of the lake.

[0003] An existing sampling device for detecting benthic animals in lakes is not convenient for staff to coordinate with the device for easy sampling of benthic animals during actual operation. Utility Model Content

[0005] This utility model is achieved by the following technical solution: a sampling device for detecting benthic animals in lakes, including a fixed base plate, a vertical plate fixedly connected to the top of the fixed base plate, an installation crossbar threadedly connected to the inside of the vertical plate, a wire harness winding drum rotatably connected to the surface of the installation crossbar, a locking ring threadedly connected to the surface of the installation crossbar, a connecting wire harness fixedly connected to the surface of the wire harness winding drum, and a wire support slidably connected to the surface of the connecting wire harness.

[0006] A sampling housing is fixedly connected to the bottom of the connecting harness. An underwater camera is fixedly connected to the front of the sampling housing. A push rod is fixedly connected to the top of the inner wall of the sampling housing. A rotating seat is fixedly connected to the output end of the push rod. A sampling bracket is rotatably connected inside the rotating seat. A rotating seat is rotatably connected inside the sampling bracket. A sampling bucket is fixedly connected to the surface of the rotating seat.

[0007] With the above technical solution, the two upright plates are symmetrically distributed on the left and right sides with the fixed base plate as the center and connected to the fixed base plate. This symmetrical structure enhances the overall stability of the device. During the sampling of benthic animals in lakes, the stable structure can ensure that the sampling device maintains a fixed position in the water, reduce shaking caused by factors such as water flow, and thus improve the accuracy of sampling.

[0008] As a further improvement to the above solution, the wire support is fixedly connected to the top of the fixed base plate, and the number of the upright plates is set to two, with the two upright plates symmetrically distributed on the left and right sides with the fixed base plate as the center.

[0009] As a further improvement to the above solution, the wire harness winding drum is located on top of the fixed base plate, and the surface of the locking ring is in contact with the surface of the upright plate.

[0010] With the above technical solution, the two upright plates are symmetrically distributed on the left and right sides with the fixed base plate as the center and connected to the fixed base plate. This symmetrical structure enhances the overall stability of the device. During the sampling of benthic animals in lakes, the stable structure can ensure that the sampling device maintains a fixed position in the water, reduce shaking caused by factors such as water flow, and thus improve the accuracy of sampling.

[0011] As a further improvement to the above solution, the number of locking rings is set to two, and the two locking rings are symmetrically distributed on the left and right sides with the mounting crossbar as the center, and the locking rings are located on the top of the fixed base plate.

[0012] As a further improvement to the above scheme, the rotating seat is located inside the sampling shell, the sampling bracket is located inside the fixed base plate, and the number of rotating seats is set to two, with the two rotating seats symmetrically distributed around the sampling shell.

[0013] As a further improvement to the above scheme, the sampling hopper is located at the bottom of the sampling shell, and the number of the sampling hopper is set to two, which are symmetrically distributed on the left and right sides with the sampling shell as the center.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features a mechanism where, once the sampling shell reaches the appropriate position, a push rod is activated. The output end of the push rod drives a rotating seat, which in turn rotates the sampling bracket. Since the sampling bracket is internally connected to the rotating seat, the sampling bucket on the rotating seat adjusts its angle as the sampling bracket rotates, allowing the sampling bucket to better contact the lake bottom. During the sampling process, an underwater camera continuously monitors the sampling situation to ensure that the sampling bucket accurately collects the target benthic animals.

[0016] This invention involves setting up a reverse-starting push rod after sampling is completed, which returns the sampling bucket to its initial position. The connecting wire harness is then retracted by rotating the wire harness reel, lifting the sampling shell and the collected benthic animal samples to the water surface, thus completing the entire sampling process. By setting up the wire harness reel, an appropriate amount of connecting wire harness is released. Since the wire harness reel is rotatably connected to the mounting crossbar and fixed between the upright plates by locking rings, it can remain stable during rotation. Attached Figure Description

A sampling bucket 14 is fixedly connected to the surface of the rotating seat 13. When the sampling housing 8 reaches the appropriate position, the push rod 10 is activated. The output end of the push rod 10 pushes the rotating seat 11, which drives the sampling bracket 12 to rotate. Since the sampling bracket 12 is rotatably connected to the rotating seat 13, the sampling bucket 14 on the rotating seat 13 will adjust its angle as the sampling bracket 12 rotates, so that the sampling bucket 14 can better contact the lake bottom. During the sampling process, the underwater camera 9 continuously monitors the sampling situation to ensure that the sampling bucket 14 accurately collects the target benthic animals.

[0028] Two upright plates 2 are symmetrically distributed around the fixed base plate 1 and connected to the fixed base plate 1. This symmetrical structure enhances the overall stability of the device. During the sampling of benthic animals in lakes, the stable structure can ensure that the sampling device remains in a fixed position in the water, reducing the shaking caused by factors such as water flow, thereby improving the accuracy of sampling.

The connecting wire harness 6 is retracted by rotating the wire harness reel 4, which lifts the sampling shell 8 and the collected benthic animal samples to the water surface, completing the entire sampling process. By setting the wire harness reel 4, an appropriate amount of connecting wire harness 6 is released. Since the wire harness reel 4 is rotatably connected to the mounting crossbar 3 and fixed between the upright plates 2 by the locking ring 5, it can remain stable during rotation.

During the sampling process, the underwater camera 9 continuously monitors the sampling situation to ensure that the sampling bucket 14 accurately collects the target benthic animals. After the sampling is completed, the push rod 10 is activated in reverse to restore the sampling bucket 14 to its initial position.
