Description

Technical Field

[0001] The invention belongs to the technical field of ecological environment monitoring, and in particular relates to an automatic collection and processing device for algae. Background Art

[0002] Attached algae refers to algae that grow on various natural and artificial substrates such as stones, aquatic higher plants, concrete structures, wooden piles, hulls or soil surfaces. Attached algae are important primary producers in aquatic ecosystems and can synthesize and convert inorganic nutrients into organisms. Attached algae live in a fixed state, have a large biofilm area, participate in the material exchange and energy cycle of water bodies, and are commonly used indicator organisms to indicate the health status of river ecosystems. At present, there are two types of technologies for collecting attached algae in water bodies. One is to lay artificial substrates in the water body and collect attached algae after a period of time. This method is affected by many natural factors. For example, it ignores the natural factor of water level changes in natural water bodies, which causes certain errors in the study of the biomass and community structure characteristics of attached algae in water bodies; the other is to collect natural aquatic plants, wooden piles, stones, etc. in the water body, scrape the attached algae with a knife or brush, and then transfer them with pure water, fix them with formaldehyde or Lugo reagent, and bring them back to the laboratory for analysis. The above two methods of collecting attached algae are both artificial techniques.

[0003] The prior art discloses a rapid algae sampling device, including an electric brush, a catheter, and a filter container. However, the electric brush of the invention is a traditional rotating brush, and lacks subsequent separation devices such as filtration, and does not have an automatic dosing and constant volume device, which is particularly unsuitable for collecting algae in water bodies with high sediment content. When this method is used to collect substrates such as wooden piles or stones at the interface of shore soil and cement, the collected algae water samples will contain a large amount of impurities such as sediment, debris, and floating objects, which seriously affects the subsequent observation and identification under a microscope and photography.

[0004] The prior art also discloses two height-adjustable algae collection devices, both of which can adjust the height manually according to the water level requirements and the environment of the sampling site, but both are manual collection methods and lack automatic processing systems such as filtering, flushing, standing and adding drugs.

The main function of the exhaust part is to release the excess air in the medicine adding bottle 13 to ensure the accuracy of the medicine amount in the medicine adding bottle 13 each time; the main function of the stopper part is to isolate the external environment on the one hand, so as not to affect the quality of the medicine, and on the other hand, to prevent the piston rod from entering the external air when the medicine is inhaled by negative pressure, thereby affecting the accuracy of the medicine amount.

The aperture of the air hose 18 is 1mm. The rotation of the dosing piston 16 can drive the adjustment block 26 to rotate synchronously. When the circular hole on the adjustment block 26 corresponds to the air channel 25, the air channel 25 and the air hose 18 can be connected. When the adjustment block 26 blocks the air channel 25, the air channel 25 and the air hose 18 are disconnected; the driving part moves slowly, and can adjust the air near the sealing block 24, so that this part of the air enters the medicine storage box 19 from the air channel 25, the circular hole and the air hose 18 in turn.

When the dosing tube plug 33 is inserted into the second dosing channel 28 , the dosing tube plug 33 pushes open the stop block 27 , and the spring 32 is compressed. At this time, the first dosing channel 29 is connected with the dosing tube plug 33 , pushing the dosing piston 16 , and the medicine flows from around the stop block 27 into the second dosing channel 28 and the dosing tube plug 33 .

[0060] By moving the dosing piston 16 away from the medicine outlet of the dosing bottle 13, negative pressure is formed in the dosing bottle 13, and the one-way valve 31 opens under the action of the negative pressure, and the medicine in the medicine storage box 19 flows into the dosing bottle 13 through the one-way valve 31. While the medicine flows in, the air inside the dosing bottle 13 floats above the medicine. When the medicine reaches a specified amount, the dosing piston 16 stops moving; the dosing piston 16 is rotated at a certain angle so that the round hole on the adjustment block 26 corresponds to the air guide channel 25, that is, the air guide channel 25 is connected to the air guide hose 18; then the fixed shaft 21 is rotated so that The adjusting screw 22 is meshed with the rack 20, the boss is in contact with the outer wall of the dosing bottle 13, the rack 20 is in the rack limiting channel 36, and the adjusting screw 22 is rotated to move the dosing piston 16 and the sealing block 24 toward the drug outlet of the dosing bottle 13 through the rack 20. The sealing block 24 compresses the medicine, so that the air above the medicine is squeezed and enters the medicine storage box 19 from the air guide channel 25, the circular hole and the air guide hose 18 in turn, thereby completing the air release; the fixed shaft 21 is restored to its initial state, the adjusting block 26 blocks the air guide channel 25, and the air guide channel 25 is not connected to the air guide hose 18.

[0061] After the preparation of the medicine in the dosing bottle 13 is completed, the dosing tube plug 33 is inserted into the second dosing channel 28, the limiting groove 35 is matched with the protrusion at one end of the stop block 27, the conical head opens the stop block 27, and the inner side of the dosing bottle 13 is connected with the inner cavity of the dosing tube plug 33. Press the dosing piston 16 in the dosing bottle 13 to inject the corresponding volume of Lugo reagent. The sample in the dosing container is taken back to the laboratory for analysis and identification.

[0062] The advantages of the present invention are:

[0063] 1. It realizes the rapid and automated sampling, pretreatment and dosing process of algae, saving time and labor costs.

[0064] 2. Through multiple bristle brushes 5. Multiple runs of automatic flushing solve the problem of biomass loss caused by the residue and destruction of attached algae caused by manual sampling. The acoustic level vibration realizes automatic sampling and improves the accuracy of quantification of attached algae.

[0065] 3. Through the two-stage filtration and sedimentation process, the purification of the algae samples is achieved, and the non-biological interferences such as mud, dead branches and leaves, and organic matter attached to the surface of stones, plant leaves, cement boards, etc. are reduced. The efficiency of traditional river and lake algae sampling is greatly improved, the purity of the algae samples and the accuracy of sample collection are improved, and the interferences such as mud, dead branches, etc. in the samples are reduced, which provides a guarantee for the accurate identification of subsequent algae samples.

[0066] 4. For the first time, the integrated design of collection, pretreatment and dosing of algae samples was realized, avoiding the errors caused by subjective manual operation. The main part of the device is made of materials such as plexiglass, polypropylene and polyester fiber. It is light in design and easy to operate, which brings great convenience to field work.

[0067] 5. The use of a drug syringe with adjustable capacity and exhaust can accurately control the amount of drug added, reduce the error in the amount of drug added, and avoid the problem of excessive or insufficient drug affecting the preservation of algae.
