specific Embodiment approach 1

[0014] Specific implementation mode one: combine Figure 1 to Figure 7 Describe this embodiment. This embodiment includes an upper casing 1, a lower casing 3, a rubber pad 4, an intermediate connecting pipe 5, an upper connecting pipe 6, a cover plate 7, a cross bar 8, at least one substrate frame 2, and at least two guide components 9 and two L-shaped handles 10, the upper end of the lower casing 3 is open and the lower end is closed, the upper end of the lower casing 3 is threaded with the middle connecting pipe 5, and the upper end of the middle connecting pipe 5 is connected to the upper casing 1 is fixedly connected, the cover plate 7 is set on the upper end surface of the upper casing 1, the upper connecting pipe 6 is arranged on the upper end of the upper casing 1 and is fixedly connected with the upper casing 1, and two L-shaped handles 10 are symmetrically arranged on the upper connecting pipe 6 and the L-shaped handle 10 is fixedly connected with the upper connecting...

specific Embodiment approach 2

[0015] Specific implementation mode two: combination figure 2 and image 3 The present embodiment will be described. The material of the matrix frame 2 of the present embodiment is stainless steel. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation mode three: combination figure 1 The present embodiment will be described. The length of the lower casing 3 of the present embodiment is 0.9 m to 1.2 m. Generally, the sampling depth is about 1.5m, and the length of the lower casing 3 meets the sampling depth within the above range, which is beneficial to the collection of algae. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

A device and a method for collecting underice periphytic algae relate to a device and a method for collecting periphytic algae to solve the problem that the periphytic algae collection cannot be completed through glass slides and polyester films during icebound seasons in northern China. The device is characterized in that an upper sleeve pipe is connected with a lower sleeve pipe through a middle sleeve pipe, and a cover plate is arranged on the upper end surface of the upper sleeve pipe; two L-shaped handles are connected with the upper sleeve pipe through an upper connection pipe, and a transverse rod is arranged inside transverse holes of the L-shaped handles; an internal swallow-tailed sheet is slidingly connected with an external swallow-tailed sheet, and a lock snap is arranged inside the internal swallow-tailed sheet and the external swallow-tailed sheet; a groove is arranged inside a substrate frame; and the upper end of the external swallow-tailed sheet on a guide part is fixed on the lower end surface of the lower sleeve pipe, and the lower end of the internal swallow-tailed sheet on the guide part is fixed on the upper end surface of a vertical plate. The method comprises: firstly, mounting a substrate glass slide; secondly, fixing the substrate frame; thirdly, placing the collection device into water; fourthly, putting heating bags in; and fifthly, taking out the collection device to complete the periphytic algae collection. The device and the method for collecting the underice periphytic algae are used for collecting the underice periphytic algae.

Description

technical field [0001] The invention relates to a collection device and method for living algae, in particular to a collection device and method for living algae under ice. Background technique [0002] At present, the collection methods of epiphytic algae include aquatic plant method, glass slide method and polyester film method. The aquatic weed method is to collect algae attached to large aquatic plants in survey waters, and no special collection tools are required. The sampling tools of the glass slide method and the polyester film method are connected by a rope. One end of the rope is connected to the float and the other end is connected to the slide frame or polyester film to attach the algae. After the experiment days are over, take out the slide from the water or film for the collection of algae. The northern part of my country is located in the temperate humid-semi-humid monsoon climate zone, with long winters, and natural water bodies are frozen for nearly 6 mont...
