Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a flow velocity adaptive synchronous stratified sampler for algae at different water depths. Background Technology

[0002] Projects such as water source condition monitoring and algae research all require sampling of water and the algae within it. However, current sampling devices typically collect a certain volume of water, then extract it to analyze the types and density of algae. Examples include a lake algae ecological sampling device disclosed in utility model patent 2020200925963. However, these traditional water sampling bottles, once opened at a certain depth, are often immediately filled with water and then retrieved to obtain a water sample at that depth for algae analysis. If the river current is fast at a certain depth, algae changes may occur very rapidly. With this method, to obtain dynamic changes in algae, it is necessary to collect samples one after another using different sampling bottles, which is time-consuming and labor-intensive. Furthermore, in waters with sparse algae, the volume of water sample obtained is limited, making it difficult to continuously obtain sufficient algae.

[0003] Secondly, in areas with fast-flowing river water, the current causes algae to change very rapidly. This sampling method cannot be used for continuous sampling, thus failing to obtain dynamic data on algae changes, and therefore requires improvement. Utility Model Content

[0004] To address the aforementioned technical problems, this invention proposes a flow velocity-adaptive synchronous stratified sampler for algae at different water depths.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A flow rate adaptive simultaneous stratified algae sampler for different water depths includes a vortex compressor module, which comprises a lower housing and an upper housing. The upper housing includes a top plate with a filter plate fixed to its outer periphery and a stationary vortex disk fixed to its bottom surface. An outlet is formed at the center of the top plate, and a continuous sampling structure is installed in conjunction with the outlet. A first waterproof motor is fixed inside the lower housing, and the first waterproof motor is connected to a moving disk. A moving vortex disk that cooperates with the stationary vortex disk is fixed to the top surface of the moving disk. Both the stationary and moving vortex disks are made of filter plates. An inlet is formed on the upper housing, and solenoid valves are installed on both the inlet and outlet. A flow meter is also installed at the inlet. A connecting ring is fixed to the outer periphery of the filter plate and is detachably fixed to the lower housing by bolts.

[0007] A further improvement is that the diameter of the filter holes on the filter plate is no greater than 0.064 mm.

[0008] In a further improvement, the continuous sampling structure includes a fixed frame fixedly connected to the lower housing, a second waterproof motor installed on the lower housing, a turntable fixedly connected to the second waterproof motor, and multiple rotating arms evenly fixed along the circumference of the turntable, with sampling bottle insertion holes formed on the rotating arms.

[0009] In a further improvement, a sampling bottle is inserted into the sampling bottle insertion hole. The sampling bottle includes a bottle body, and the bottle body is connected to a bottle mouth through a bottle neck. An annular groove corresponding to the bottle mouth is formed on the top surface of the upper shell. The cross-section of the annular groove is T-shaped. The water outlet is connected to the annular groove. An exhaust valve is installed on the bottle body.

[0010] In a further improvement, a circular insertion port is formed on the annular groove, and cover plates are placed on both sides of the circular insertion port to maintain the integrity of the annular groove. The cover plates are detachably fixed to the upper housing.

[0011] In a further improvement, the cover plate has a protruding connecting part, which is detachably fixed to the upper housing by bolts.

[0012] As a further improvement, a rubber sealing gasket is laid inside the annular groove.

[0013] As a further improvement, the lower housing is connected to a telescopic rod.

[0014] As a further improvement, a miniature water pump is installed at the water outlet.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention can concentrate algae, thereby enabling continuous large-scale algae sampling of water samples. This overcomes the shortcomings of existing sampling devices, which are limited by container volume, resulting in small sample volumes and the inability to continuously sample and obtain dynamic change data.

[0024] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples.

[0025] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0026] Example 1: A flow rate adaptive algae synchronous stratification sampler for different water depths includes a vortex compressor module 10, a lower housing 1, a first waterproof motor 11, a moving disc 12, a moving vortex disc 13, an upper housing 2, a top plate 21, a filter plate 22, a stationary vortex disc 23, an outlet 24, an inlet 25, a solenoid valve 26, a flow meter 27, a connecting ring 28, a continuous sampling structure 3, a fixing frame 31, a turntable 32, a rotating arm 33, a sampling bottle insertion hole 34, a bottle body 341, a bottle neck 342, a bottle mouth 343, an exhaust valve 344, an annular groove 345, a circular insertion port 36, a cover plate 37, a connecting part 38, a bolt 39, a rubber sealing gasket 310, and a telescopic rod 4.

[0027] The lower housing 1 and the upper housing 2 are interlocked, allowing the stationary scroll 23 and the moving scroll 13 to cooperate and form a scroll compressor structure. The moving scroll 13 is connected to the first waterproof motor 11 via the moving plate 12. Since water is incompressible, unlike gas, both the stationary scroll 23 and the moving scroll 13 are made of filter plates, and a filter plate 22 is fixed to the outer periphery of the top plate 21. Thus, when the stationary scroll 23 and the moving scroll 13 move relative to each other, excess water is filtered out and flows to the outside through the filter plate 22.

[0028] An inlet 25 is formed on the upper housing 2. Solenoid valves 26 are installed on both the inlet 25 and the outlet 24. A flow meter 27 is also installed at the inlet 25. A sampling bottle is installed at the outlet 24, and an exhaust valve 344 is installed on the sampling bottle.

[0029] Its usage method is as follows:

[0030] The device is flipped into the water so that the inlet 25 faces the direction of water flow, allowing water to enter the upper housing 2 and be measured by the flow meter 27. Algae in the water are retained inside the upper housing 2 by the filter plate. Then, the first waterproof motor 11 drives the rotating vortex disk 13 to rotate. If it is a gaseous medium, the relative movement of the rotating vortex disk 13 and the stationary vortex disk 23 will compress the gas. In this invention, the rotating vortex disk 13 and the stationary vortex disk 23 also compress the water, but excess water flows out through the filter holes on the filter plate, exiting the compressed space formed by the rotating vortex disk 13 and the stationary vortex disk 23, while the algae are retained, thus achieving further concentration of the algae. After reaching the preset concentration volume, the valve at the outlet 24 opens, allowing the concentrated algae solution to enter the sampling bottle, thereby achieving large-scale algae sampling of water samples and simultaneous sampling of water from corresponding water layers. Since the flow meter 27 records the volume of water containing algae entering, the types and quantities of algae can be detected to investigate algae species and density.

[0031] At the same time, the components of various pollutants in the water are detected to obtain the correlation between water quality and algae.

[0032] Furthermore, a water velocity sensor can be installed on the lower housing 1 or the upper housing 2 to detect the water flow velocity at the location where the device is placed, and the amount of water entering each time can be controlled based on the detected flow velocity.

[0033] Furthermore, to obtain dynamic change data of algae, a continuous sampling structure 3 is set up. The continuous sampling structure 3 includes a fixing frame 31 fixedly connected to the lower shell 1. A second waterproof motor 35 is installed on the lower shell 1. The second waterproof motor 35 is fixedly connected to a turntable 32. Multiple rotating arms 33 are evenly fixed along the circumference of the turntable 32. Sampling bottle insertion holes 34 are formed on the rotating arms 33. A sampling bottle is inserted into the sampling bottle insertion hole 34. The sampling bottle includes a bottle body 341, and the bottle body 341 is connected to a bottle mouth 343 through a bottle neck 342. An annular groove 345 corresponding to the bottle mouth 343 is formed on the top surface of the upper shell 2. The cross-section of the annular groove 345 is T-shaped. The outlet 24 is connected to the annular groove 345. An exhaust valve 344 is installed on the bottle body 341.

[0034] In this way, after each sampling, the second waterproof motor 35 drives the turntable 32 to rotate at a certain angle, so that the other sampling bottle is aligned with the water outlet 24. This enables continuous sampling, allowing for continuous sampling at the same water layer or obtaining samples at different water depths.

[0035] To facilitate the insertion of the sampling bottle into the annular groove 345, a circular insertion port 36 is formed on the annular groove 345. The circular insertion port 36 is covered with cover plates 37 on both sides to maintain the integrity of the annular groove 345. The cover plates 37 are detachably fixed to the upper housing 2. The cover plates 37 have a protruding connecting part 38, which is detachably fixed to the upper housing 2 by bolts 39.

[0036] When inserting the sampling bottle, remove the cover plate 37, align the sampling bottle insertion hole 34 with the circular insertion port 36 one by one, and then insert the sampling bottle. After all the bottles are inserted, install the cover plate 37 to prevent the sampling bottle from falling out of the circular insertion port 36.

[0037] The diameter of the filter holes on the filter plate is no greater than 0.064 mm to prevent algae from passing through.

[0038] The filter plate 22 is fixed with a connecting ring 28 that is detachably and fixedly connected to the lower housing 1 by bolts.

[0039] The annular groove 345 is lined with a rubber sealing gasket 310, which has achieved a seal on the bottle opening.

[0040] The lower housing 1 is connected to a telescopic rod 4, which allows the operator to insert the scroll compressor module into the water flow.

[0041] A miniature water pump is installed at the 24 outlets. When it is necessary to send the concentrated water sample into the sampling bottle, the miniature water pump is turned on to help the concentrated water sample enter the sampling bottle smoothly.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
