Embodiment 1

[0028] refer to Figure 1-3 , a sampling device based on river ecological detection, comprising a bottom plate 1, the top outer wall of the bottom plate 1 is connected with a bearing seat 19 by bolts, and the bottom inner wall of the bearing seat 19 is rotatably connected with a fixed column 20, and the top outer wall of the fixed column 20 is connected by bolts The driven gear plate is connected, the top outer wall of the bottom plate 1 is connected with the third motor 2 by bolts, and the outer wall of the output shaft of the third motor 2 is fixedly connected with the driving gear plate 3, and the outer wall of the driving gear plate 3 is connected with the driven gear plate. The gear plates mesh with each other, and the top outer wall of the driven gear plate is connected with a fixed sleeve 5 by bolts, and the top outer wall of the fixed sleeve 5 is inserted with a slide bar 7, and the top outer wall of the slide bar 7 is connected with a top plate 8 by bolts, And the bot...

Embodiment 2

[0032] refer to Figure 4 , a sampling device based on river channel ecological detection. Compared with Embodiment 1, the outer wall of the bottom of the sampling cylinder 25 is connected with a support plate 34 by bolts, and the outer wall of one side of the support plate 34 is connected to the filter screen 29 through a hinge. connect.

[0033] Working principle: At the same time, the filter screen 29 is connected to the support plate 34 through hinges, so it will not affect the sampling work of the sampling cylinder 25 .

Embodiment 3

[0035] refer to Figure 5 , a sampling device based on river ecological detection. Compared with Embodiment 1, this embodiment has a threaded hole on the top outer wall of the bottom plate 1, and a fixed screw 35 is threaded inside the threaded hole.

[0036] Working principle: when people need to perform sampling work, they can rotate the fixed screw rod 35 to drill the fixed screw rod 35 into the soil, thereby ensuring the stability of the device during operation.

Abstract

The invention provides a sampling device based on river channel ecological detection. The device comprises a bottom plate, a bearing seat is arranged on the outer wall of the top of the bottom plate,a fixing column is rotatably connected with the inner wall of the bottom of the bearing seat, a driven gear disc is arranged on the outer wall of the top of the fixing column, and a third motor is arranged on the outer wall of the top of the bottom plate. When people need to sample and detect sludge in a river channel, a sliding rod can be pulled to adjust the height of the device firstly, then the third motor and a first motor are started separately, the third motor drives a driving gear disc to rotate, and a sampling cylinder can be rotated to the position above the river through meshing between the driving gear disc and the driven gear disc; then the first motor drives a threaded lead screw to rotate, the sampling cylinder can be transversely adjusted, sludge in different position areasof the river can be sampled, the sampling diversity is improved, and the sampling requirements of people are met.

Description

technical field [0001] The invention relates to the technical field of river channel sampling, in particular to a sampling device based on river channel ecological detection. Background technique [0002] Ecological monitoring refers to the use of physical, chemical, biochemical, ecological and other technical means to monitor and test the various elements in the ecological environment, the relationship between organisms and the environment, and the structure and function of the ecosystem. [0003] After searching, the Chinese patent application number is CN109060431B, which discloses a kind of automatic sampling device for river pollution detection bottom silt, including a workbench, the top of the workbench is fixedly connected with a support frame, and auxiliary Frame, the top of the workbench is located inside the support frame and is fixedly connected with a rotating motor, the rotating motor is connected to the first pulley through the output shaft, the first pulley pa...
