Description

Technical Field

[0001] The invention relates to the technical field of watershed biological monitoring and sampling, in particular to a watershed biological diversity monitoring and sampling device. Background Art

[0002] A river basin is a river catchment area surrounded by a watershed. Plankton refers to drifting organisms that live in water but lack the ability to move effectively. They are divided into phytoplankton and zooplankton. Some plankton have the ability to swim, but their swimming speed is often slower than the speed of the ocean current in which they are located, so they cannot swim flexibly and effectively in the water. Plankton, among the organisms in water bodies such as oceans, lakes and rivers, has no ability to move at all, or its ability is very weak, so it cannot move against the current, but floats on the water surface. This type of organism is collectively called plankton. Plankton occupies an important position in the food chain of aquatic ecosystems. Plankton is an economic aquatic animal. In addition to affecting fisheries, plankton also has the following practical significance. It can be used as an indicator species of ocean currents and is helpful in exploring the direction of ocean currents. Therefore, in the process of investigating the river basin, plankton is often collected for various tests to infer the ecological environment of the river basin. Therefore, it is necessary to use sampling devices to collect seawater samples at various depths, and multiple sampling is required to obtain seawater samples at various depths.

[0003] A plankton sampling device with the Chinese authorization announcement number CN207540804U is provided. A supporting side plate is welded on the supporting side plate, and a fixing plate is welded on the fixing plate. The sieve silk can be fixed on the fixing plate by the cooperation of an adjusting handle and an adjusting rod. The sieve silk can be adjusted in the horizontal direction by the adjusting handle, and the stretching degree of the sieve silk can be adjusted to adapt to the impact of seawater in different situations. At the same time, it can be fixed by a locking device, which is convenient for replacing the sieve silk and collecting organisms therein.

[0004] However, this patent still has certain shortcomings when in use. The existing plankton collection device can only collect one sample at a time during the collection process. The sampling device collects seawater samples after reaching the specified depth. It needs to be operated multiple times to obtain seawater samples at various water depths, which makes sample collection extremely cumbersome, time-consuming and labor-intensive. In addition, the existing sampling device cannot realize automatic sampling, requires manual operation and cannot roughly separate the collected water samples, which is very inconvenient to operate. Summary of the invention

When the sampling bottle needs to be installed, the sampling bottle is first clamped into the clamping block, and then the two sliders at the bottom of the second fixed plate are pushed in the opposite direction. At this time, the spring is squeezed, and then the sampling bottle is moved downward along the clamping block, so that the fixed block is aligned with the limit groove for placement, and then the two sliders are released. Under the action of the spring rebound, the two sliders move toward the middle, and the sides of the two sliders are abutted against the clamping groove, so that the sampling bottle is fixed and installed, making it convenient to install and replace the collection bottle, convenient for the operator to take samples, avoiding the reduction in accuracy caused by repeated use of the sampling bottle, and making the monitoring results more accurate.

When it is necessary to sample the watershed organisms, the traction rope is first bound, and then the sampling device is placed in the watershed to be monitored. The device moves downward under the action of the counterweight block, and the controller is controlled to control the electric telescopic rod to extend and retract. When sampling is required, the controller controls the electric telescopic rod to retract, and the bottle stopper and the sampling bottle are separated. The water sample enters from the top of the sampling bottle. After the sampling is completed, the controller controls the electric telescopic rod to extend so that the bottle stopper and the sampling bottle are engaged to seal the sampling bottle. When sampling is required in another river basin, the remaining collection components can be repeated. The position of the sampling device can be located by the position of the float during the sampling process. After the sampling is completed, the traction rope is pulled to move the sampling device upward. When the sample needs to be roughly separated, the filter is hooked out of the sampling bottle. The filter contains plankton and the sampling bottle contains the collected water sample, so the sample can be roughly separated. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting slot 18 is provided at the top of the second fixing plate 8, and a sliding slot 14 is provided at the bottom of the second fixing plate 8. A spring 16 is provided in the sliding slot 14. One end of the spring 16 is fixedly connected to the side wall of the sliding slot 14, and the other end of the spring 16 is elastically connected to a slider 15. A damping rod 17 is provided inside the spring 16. The slider 15 is slidably connected to the second fixing plate 8, and the side of the slider 15 abuts against the slot 607.

[0027] Among them, by setting up multiple collecting components 6, the problem that the collection device cannot collect multiple samples during the collection process is solved, and multiple groups of data are collected at one time, and the sampling bottle 601 can be easily installed. When the sampling bottle 601 needs to be installed, the sampling bottle 601 is first clamped into the clamping block 12, and then the two sliders 15 at the bottom of the second fixed plate 8 are pushed in the opposite direction. At this time, the spring 16 is squeezed, and then the sampling bottle 601 is moved downward along the clamping block 12, so that the fixed block 606 is aligned with the limit groove 18 for placement, and then the two sliders 15 are released. Under the action of the spring 16 rebound, the two sliders 15 move toward the middle, and the sides of the two sliders 15 are abutted against the clamping groove 607, thereby realizing the fixation and installation of the sampling bottle 601, which is convenient for the operator to take samples, avoids the reduction in accuracy caused by repeated use of the sampling bottle 601, and makes the monitoring results more accurate.

[0028] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the first fixed plate 1 is fixedly connected to an electric telescopic rod 10, and the electric telescopic rod 10 is electrically connected to the controller 4. The bottom of the electric telescopic rod 10 is fixedly connected to a bottle stopper 11, and the diameter of the bottle stopper 11 is equal to the diameter of the bottle mouth of the sampling bottle 601, and the material of the bottle stopper 11 is rubber.

[0029] Among them, by setting up the controller 4, the collecting component 6, the electric telescopic rod 10 and the bottle stopper 11, the problem that the existing sampling device cannot realize automatic sampling, needs manual operation and cannot separate the collected water samples is solved. When it is necessary to sample the watershed organisms, the traction rope 2 is first bound, and then the sampling device is placed in the watershed that needs to be monitored. The device moves downward under the action of the counterweight 5, and the controller 4 is controlled to control the electric telescopic rod 10 to extend and retract. When sampling is required, the controller 4 controls the electric telescopic rod 10 to retract, and the bottle stopper 11 and the sampling bottle 601 are separated, and the water sample in the watershed is separated from the sampling bottle 601. The top of the sampling bottle 601 is entered. After the sampling is completed, the controller 4 controls the electric telescopic rod 10 to extend, so that the bottle stopper 11 and the sampling bottle 601 are engaged to seal the sampling bottle 601. When it is necessary to sample in another watershed, the remaining collecting components 6 can be repeated. The position of the sampling device can be located by the position of the float 3 during the sampling process. After the sampling is completed, the traction rope 2 is pulled to move the sampling device upward. When it is necessary to roughly separate the sample, the filter element 605 is hooked out of the sampling bottle 601. The filter element 605 contains plankton, and the sampling bottle 601 contains the collected water sample, so the sample can be roughly separated.

[0030] The working process of the present invention is as follows: when a watershed biodiversity monitoring sampling device designed by the present invention is in operation, when sampling of watershed organisms is required, the traction rope 2 is first bound, and then the sampling device is placed in the watershed to be monitored. The device moves downward under the action of the counterweight 5, and the controller 4 is controlled so that the controller 4 controls the extension and retraction of the electric telescopic rod 10. When sampling is required, the controller 4 controls the electric telescopic rod 10 to retract, and the bottle stopper 11 and the sampling bottle 601 are separated, and the water sample in the watershed enters from the top of the sampling bottle 601. After the sampling is completed, the controller 4 controls the electric telescopic rod 10 to extend, so that the bottle stopper 11 and the sampling bottle 601 are engaged to seal the sampling bottle 601. When sampling is required in another watershed, the remaining collecting components 6 can be repeated. The position of the float 3 can be used to adjust the sampling rate during the sampling process. The sampling device is positioned. After sampling is completed, the traction rope 2 is pulled to move the sampling device upward. When it is necessary to roughly separate the sample, the filter element 605 is hooked out from the sampling bottle 601. The filter element 605 contains plankton, and the sampling bottle 601 contains the collected water sample. The sample can be roughly separated. When it is necessary to install the sampling bottle 601, the sampling bottle 601 is first clamped into the clamping block 12, and then the two sliders 15 at the bottom of the second fixed plate 8 are pushed in the opposite direction. At this time, the spring 16 is squeezed, and then the sampling bottle 601 is moved downward along the clamping block 12, so that the fixed block 606 is aligned with the limiting groove 18 for placement, and then the two sliders 15 are released. Under the action of the spring 16 rebounding, the two sliders 15 move toward the middle, and the sides of the two sliders 15 are abutted against the card groove 607, thereby realizing the fixation and installation of the sampling bottle 601.
