Abstract
Description
Technical Field
[0001] This utility model relates to the field of ecological environment monitoring technology, specifically to a water plankton sampling device. Background Technology
[0002] Ecological and environmental monitoring refers to the systematic monitoring and analysis of various elements in the ecological environment using modern scientific and technological methods. This aims to assess the quality, health status, and trends of the ecological environment, providing a scientific basis for ecological protection, pollution control, and ecological restoration. Monitoring includes the structure and function of ecosystems, such as vegetation cover, biodiversity (e.g., the types and quantities of plants, animals, and microorganisms), and ecosystem service functions (e.g., water conservation, soil retention, carbon sequestration). Ecological monitoring reflects the health status and stability of ecosystems, providing scientific support for ecological protection and restoration.
[0003] Water environment testing includes testing of surface water (such as rivers, lakes, and reservoirs), groundwater, drinking water sources, and seawater. Testing indicators cover physicochemical indicators (such as pH, dissolved oxygen, chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen, and heavy metals), biological indicators (such as plankton and benthic organisms), and microbiological indicators (such as E. coli). Through these tests, it can be determined whether the water body is polluted and whether it is suitable for drinking, irrigation, or ecological use.
[0004] As organisms in aquatic bodies, plankton co-create aquatic ecosystems with other organisms. However, current environmental pollution is quite serious, leading to a decrease in plankton in the water, which in turn reduces the oxygen supply in the water and affects the ecosystem. Therefore, it is often necessary to collect and test plankton.
[0005] Authorization announcement number CN217738736U discloses a water plankton sampling device. This patented technology collects plankton from the water through the cooperation of a threaded ring, a second mounting tube, a second fan blade, a second mounting frame, a second waterproof motor, and a filter screen. The installation block is submerged through the cooperation of a water pump and a water-holding chamber, causing the left side of the second mounting tube to submerge underwater, thereby collecting the plankton. The installation block is moved through the cooperation of a first mounting tube, a first fan blade, and a first waterproof motor. However, this plankton sampling device has many shortcomings, such as difficulty in accurately controlling the sampling depth, low sampling efficiency, and significant damage to plankton, which seriously affects the accuracy and efficiency of the research. Therefore, there is a need for an improved water plankton sampling device to address these issues. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] For examples, please refer to Figures 1-4 This utility model provides a technical solution:
[0028] A planktonic sampling device includes a main body 1, a sampling drive component 2 is installed inside the main body 1, and a control collection component 3 is fixedly connected inside the main body 1.
[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sampling drive assembly 2 includes a bracket 201, a motor 202 mounted on the top of the bracket 201, a tube wheel 203 fixedly connected to the output end of the motor 202, a sinking tube 205 fixedly connected to the bottom of the tube wheel 203, a sampling cylinder 207 fixedly connected to the bottom of the sinking tube 205, a depth sensor 208 fixedly connected to the sampling cylinder 207, and a connecting pipe 209 fixedly connected to the side of the tube wheel 203. The control collection assembly 3 includes a support plate 301, a circuit board 305 fixedly connected to the top of the support plate 301, a power supply 306, a microprocessor 307, and a positioning module 308 fixedly connected to the top of the circuit board 305. The depth sensor 208 can accurately control the sampling depth. To meet different research needs, the motor 202 drives the tube wheel 203 to wind up the sinking tube 205. This automated control drive mechanism can quickly complete sampling and can also drive the sampling cylinder 207 to move up and down in the water to achieve sampling at different depths, greatly improving sampling efficiency.
[0030] The sinking tube 205 has a weight-increasing device 206 fixedly connected to its bottom. Two supports 201 are provided, and a bearing 204 is fixedly connected to the top of the support 201. The tube wheel 203 extends into the bearing 204. The power supply 306, microprocessor 307, and positioning module 308 are electrically connected. A pump body 302 is installed on the top of the support plate 301, and a connecting pipe 209 extends into the pump body 302. A sample collection container 304 is fixedly connected to the top of the support plate 301. An output pipe 303 is fixedly connected to the side of the pump body 302 and extends into the sample collection container 304. The microprocessor 307 controls the operation of the depth control mechanism and the drive mechanism to achieve automated sampling. The inner wall of the sampling tube 207 is smooth to avoid the attachment and damage of plankton during the sampling process. Automated sampling is achieved through the control unit. The operation is simple and easy to use. The sample collection container 304 can be used to store the plankton samples after sampling to avoid sample contamination.
[0031] In this embodiment, as Figure 1 As shown, the main body 1 includes a float 101, which is made of lightweight foam material. A lamp body 102 is fixedly connected to the top of the float 101, and a sign 103 is fixedly connected to the side of the float 101.

The microprocessor 307 adjusts the sampling depth of the sampling tube 207 according to the preset depth value through the depth control mechanism. The drive mechanism drives the sampling tube 207 to move up and down in the water to complete sampling at different depths. After sampling, the plankton samples flow into the sample collection container 304 through the pipe. After sampling is completed, the device automatically returns to the water surface, which facilitates sample collection and subsequent processing. The float 101 is made of lightweight foam material and has good buoyancy performance. The sampling tube 207 is made of transparent plastic. The depth control mechanism includes a high-precision depth sensor 208, and the drive mechanism is driven by a micro motor 202.
