Problems solved by technology

This method is simple and direct, but there are some disadvantages, because in the actual field monitoring process, these substrates are not easy to find, and there are abundant epiphytic algae growing on steep banks, barges, ships or buoys in the water, which is bound to It has become the target of collecting algae, but the staff in these places cannot collect it with the above methods, and even spend a lot of effort on the ground to get it. Not only the samples collected are limited, but also the safety is particularly poor. People are in danger of falling into the water if they are not careful

Embodiment 1

[0026] Such as Figure 1~2 As shown, a collection device suitable for growing algae includes a collection mechanism 1, a net pocket 2, and a sample collector 4 arranged sequentially from top to bottom, the collection mechanism 1 is provided with an upper opening and a lower opening, and the net pocket 2 is arranged in an inverted bell shape, and it is provided with an upper opening and a lower opening. The net pocket 2 is made of silk yarn, so that it can be dragged and cleaned in water after the sample is collected. The mesh number of described net bag 2 can be changed according to the size of sample. The upper opening of the collection mechanism 1 is provided with an arc-shaped protruding collection end 1041, and the thickness of the collection end 1041 decreases sequentially from bottom to top. This setting makes the edge of the collection end 1041 relatively sharp, which is conducive to scraping algae samples . The lower opening of the collection mechanism 1 is detachabl...

Embodiment 2

[0037] Such as Figure 5 As shown, a collection device suitable for growing algae includes a collection mechanism 1, a net pocket 2, and a sample collector 4 arranged sequentially from top to bottom, the collection mechanism 1 is provided with an upper opening and a lower opening, and the net pocket 2 is arranged in an inverted bell shape, and it is provided with an upper opening and a lower opening. The net pocket 2 is made of silk yarn, so that it can be dragged and cleaned in water after the sample is collected. The mesh number of described net bag 2 can be changed according to the size of sample. The upper opening of the collection mechanism 1 is provided with an arc-shaped protruding collection end 1041, and the thickness of the collection end 1041 decreases sequentially from bottom to top. This setting makes the edge of the collection end 1041 relatively sharp, which is conducive to scraping algae samples . The lower opening of the collection mechanism 1 is detachably ...

Abstract

The invention relates to a collecting device suitable for periphytic algae. The collecting device comprises a collecting device, a string bag and a sample collector which are sequentially arranged from top to bottom and is characterized in that the collecting mechanism is provided with an upper opening and a lower opening, the string bag is arranged in an inverted bell shape and provided with an upper opening and lower opening, the upper opening of the collecting mechanism is provided with an arc-shaped protruding collecting end, the lower opening of the collecting mechanism is detachably hermitically connected with the upper opening of the string bag, and the lower opening of the string bag is hermitically connected with the upper portion of the sample collector; the collecting mechanism is further provided with a rotating mechanism and a telescopic rod, and the telescopic rod is hinged to the collecting mechanism through the rotating mechanism. The collecting device which is a sampling tool suitable for wild aquatic organism monitoring is simple in structure, convenient to operate, simple in sample cleaning, capable of being detached and folded, portable and capable of satisfying outdoor periphytic alga sampling requirements.

Description

technical field [0001] The invention relates to the technical field of ecological environment monitoring, in particular to a collection device suitable for growing algae. Background technique [0002] As the main primary producer of aquatic ecosystems, epiphytic algae are also an important link in the food chain. They can transfer inorganic nutrients to higher-level organic life forms, and are responsible for the important tasks of material circulation and energy flow. They are mainly attached to stones. , Aquatic plants, sediments, sand grains, aquatic animals and other substrates are highly sensitive to external disturbances and can reflect the water quality to some extent. Algae growth is one of the important indicators to evaluate whether the ecological environment of a water area is good. [0003] At present, the collection of epiphytic algae is mainly to brush the algae living on substrates such as stones, wood or plants into sample bottles with tools such as toothbrus...
