Description
Technical Field
The utility model relates to an alga collection system technical field especially relates to an attached alga collection system of flat matrix under water.
Background
The periphyton algae has good application prospect as one of important indexes for evaluating whether the ecological environment of the water area is good or not. The method can accurately reflect the change of the water area condition of the periphyton algae in the river with relatively large flow velocity, is beneficial to the protection and sustainable development of the water area environment through quantitative research on the algae in the water body, and can provide scientific guidance for fishery resource development.
The algae is characterized in that the individual is small, the algae usually exists in a unicellular or colony state, and the algae floats in the nutrient or lives in the epiphytic environment and is widely distributed in water bodies such as lakes, rivers, marshes and the like. Algae are important targets for biological and ecological research. In phytoplankton research, phytoplankton is generally used to catch algae living in plankton, and many specimens can be obtained in a short time.
However, the epiphytic algae often adhere to walls, the surface of stones in water, the stems of aquatic higher plants, the surface of leaves falling into water, and the like. Therefore, when collecting periphyton specimens, it is common to scrape off specimens on the surface of stones or cut off stems of aquatic higher plants to obtain specimens.
A portable periphyton algae sampler (patent number: CN201810898374) disclosed by Chinese patent realizes the collection of attached algae in two ways, wherein the first way is as follows: when the sampler collects the sample of the substrate-pickable periphytic algae, the water storage bottle is filled with distilled water or ultrapure water and screwed on the shell. The representative attached substrate of the attached algae is randomly selected and picked up, the substrate is vertically held by hands, and the convenient sampler of the attached algae is vertical to the attached surface of the substrate during operation. The flexible sealing cover is tightly buckled on the substrate, the surface of the substrate is tightly attached, a power switch is turned on, the motor drives the brush to start operating through the transmission shaft, meanwhile, the distilled water or ultrapure water in the water storage bottle is pumped to the operating surface through the first water pump guide pipe by the micro water pump, the brush cleans down the algae on the substrate, and the algae sample flows into the guide pipe through the sample collecting port and finally enters the sample collecting bottle. The second way is: when a sampler collects samples of attached algae of a non-pickable substrate, representative attached algae substrates are randomly selected, a sleeve and the front section of the sleeve stretch into the water during operation, a flexible sealing cover is tightly buckled on the substrate to enable the surface of the substrate to be tightly attached, a power switch is turned on, a motor drives a brush to start operation through a transmission shaft, natural water enters a brush cavity after being filtered through a water inlet, the brush scrubs the attached algae on the substrate, a micro water pump conveys the attached algae samples obtained by scrubbing to a second water pump conduit through a first water pump conduit and enters a sample collecting bottle through the conduit. The sampler can collect samples of the attached algae on the surface of the pickup and non-pickup substrates through different structural forms, and has good applicability. However, when the sampler works, the brush is continuously driven to rotate by the motor, so that the algae on the surface of the substrate are brushed down, the brush is washed by the first water pump guide pipe under the action of the micro water pump, the washed algae fall into the sleeve and finally flow into the sample collecting port to enter the sample collecting bottle, or flow through the second water pump guide pipe to enter the sample collecting bottle to finish collection, and the collection quantity of the algae is uncontrollable during collection. The acquisition time of the collector is long, the time for single acquisition is 3-5min, and the rapid acquisition can be realized.
The traditional method is to use tweezers, a knife or scissors for scraping and collecting. Carry and alternate the more collection instrument of use when gathering in the field, all very inconvenient. Therefore, the utility model provides an underwater flat-bottom substrate attached algae collecting device, which is specially used for algae sampling of flat-bottom substrates, and has the advantages of small volume, easy carrying and convenient use; this device adopts the mode of scraping to take the algae sampling, is convenient for control the biomass, carries out quantitative collection.
