Periphytic algae sampling device

Abstract

The invention provides a periphytic algae sampling device. The periphytic algae sampling device comprises a handle, a hollow connecting rod, a cable, a cable driving component and a sampling barrel, the periphytic algae sampling device is characterized by: the cable driving component is arranged on the handle, the handle is connected with the upper end of the hollow connecting rod, and the lower end of the hollow connecting rod is connected with the sampling cylinder; a separator is arranged in the sampling barrel, a through hole is arranged on the separator, a movable plug is arranged on thetop surface of the separator, and the movable plug can cover the through hole; a first rotating shaft is arranged on the bottom surface of the separator, a rotating disc is arranged on the first rotating shaft, and a brush body is arranged on the bottom surface of the rotating disc; a torsion spring is arranged between the rotating disc and the separator, and a cable arrange groove is arranged onthe side surface of the rotating disc; the cable passes through the hollow connecting rod, the upper end of the cable is connected with the cable driving component, and the lower end of the cable is fixedly connected with the cable arrange groove on the side surface of the rotating disc. According to the periphytic algae sampling device, periphytic algae and in situ water can be collected at the same time, the periphytic algae sampling device is convenient to use and can greatly improve the sampling efficiency.

Description

technical field

[0001] The invention relates to the technical field of aquatic biological sample collection devices, in particular to a device for collecting algae and in-situ water. Background technique

[0002] Freshwater algae have a short life cycle and strong fixation. They are located at the bottom of the food chain and are the main primary producers in the environment. They are very suitable indicator organisms for water quality. Algae refers to the presence of various substrates (such as stones, aquatic higher plants, sand and mud, wooden piles sunk in water, ship hulls, and glass slides, plastic plates or films placed in water for the purpose of collecting algae, etc.) ) attached algae.

[0003] During the sample collection experiment process against algae, the substrate at the position of the sampling point (usually 20-50 cm below the water surface) is usually selected to collect the algae on the substrate; at the same time, the water at the sampling point (in-sit...

Embodiment Construction

[0022] Below in conjunction with preferred embodiment and appended Figure 1~6 The present invention will be further described in detail, and more details are set forth in the following description so as to fully understand the present invention. However, the content of this specific embodiment should not limit the protection scope of the present invention. It should be noted that the drawings are only examples, not drawn according to the same scale, and should not be taken as limitations on the actual scope of protection of the present invention.

[0023] Such as Figure 1~6 As shown, an epiphyte sampling device of the present invention includes a handle 1 , a hollow connecting rod 2 , a cable 3 , a cable driving part 4 and a sampling cylinder 5 .

[0024] Wherein, the sampling cylinder 5 is a cylindrical cylinder body, and a partition plate 6 is provided at the lower part inside. The partition plate 6 separates the cylinder body into upper and lower parts, and the partitio...
