Problems solved by technology

[0004] At present, there are not many devices used to measure the migration rate of algae, and they are generally large-scale devices used in laboratories. Although the test results are accurate, for technicians who have been working in the field for a long time, large-scale devices are obviously not portable
In addition, for algae-type water samples in the field, direct on-site measurement cannot be carried out quickly, and the water samples need to be properly preserved and brought back to the laboratory for measurement. changes, its migration rate will also be affected, and it is impossible to truly restore the migration characteristics of algae in situ

Embodiment 1

[0021] Embodiment 1: as figure 1 , 2 A kind of portable water body phytoplankton migration rate measuring device shown in , 3 and 4, described measuring device is cylinder body 1, and the upper and lower ends of cylinder body 1 are connecting port 2, and described cylinder body The communication port 2 at the upper end of 1 is provided with a sealing upper cover 3, the communication port 2 at the lower end of the cylinder body 1 is provided with a sealing base 4, the middle part of the cylinder body 1 is provided with a layered assembly, and the layered assembly is composed of a circle Ring-shaped spring sheet 7, circular elastic film 13 and positioning rod 6 are formed, the outer edge of the elastic film 13 is fixedly connected to the inner side of the spring sheet 7, and the diameter of the spring sheet 7 is the same as the inner diameter of the cylinder 1 , the spring piece 7 is composed of a fixed section 7-1 and a movable section 7-2, the fixed section 7-1 is fixedly con...

Embodiment 2

[0022] Embodiment 2: as figure 1 , 2 , 3 and 4, the length of the fixed section 7-1 of the spring leaf 7 is the same as the length of the movable section 7-2, and the inner wall of the cylinder 1 and the contact position of the spring leaf 7 movable section 7-2 are provided with An arc-shaped sealing layer 11; under the action of the positioning rod 6, the spring leaf 7 can be bent forward or reversely in the cylinder 1. In order to ensure the sealing of the spring leaf when it is bent forward, when it is bent backward Adhesion with the inner surface of the cylinder 1, the length of the fixed section 7-1 is the same as that of the movable section 7-2; at the same time, an arc-shaped sealing layer 11 on the inner wall of the cylinder 1 is the same as the inner diameter of the cylinder 1 , to facilitate the close contact between the spring sheet 7 and the inner wall of the cylinder body 1, and ensure the sealing effect of the layering device during layering.

Embodiment 3

[0023] Embodiment 3: as figure 1 , 2 , 3 and 4, the inner surface of the cylinder 1 is provided with an inwardly recessed arc groove 12, and the fixed section 7-1 of the spring leaf 7 is fixedly installed on the bottom of the arc groove 12; since the equipment is carrying out algae When migrating, the inside of the cylinder body 1 needs to be penetrated up and down in the early stage. When the movable section 7-2 of the spring piece 7 is bent in the opposite direction, since the elastic film 13 and the spring piece 7 itself occupy a certain space, in order to ensure that the inside of the cylinder body 1 There is no obstacle, so the movable section 7-2 of the spring leaf 7 and the elastic film 13 need to be accommodated in the arc-shaped groove 12, so as to ensure the implementation effect of the device.

Abstract

The invention discloses a portable water body phytoplankton migration rate measurement device, which is a cylindrical barrel, wherein the upper and lower ends of the barrel are both vent ports, a layering component is arranged at the middle part of the barrel; the layering component is composed of a toroidal spring leaf, a round elastic film and a locating lever; the outer side of the elastic film is fixedly connected with the inner side of the spring leaf, the diameter of the spring leaf is the same as the inner diameter of the barrel, the spring leaf is composed of a fixed section and a movable section, the fixed section is fixedly connected on the inner surface of the barrel, a through hole is formed in the middle point of the fixed section of the spring leaf, the transversely-installed locating lever is arranged inside the through hole, one end of the locating lever is fixedly connected to the inner side of the spring leaf, and the other end of the locating lever is connected to the outer side of the barrel. The device disclosed by the invention has a smart structure, and is convenient to be carried by researchers; during migration operation, the device is through in the vertical direction; and after the migration operation, accurate layering is realized through the layering device, the sealing effect is good, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the detection field of the migration rate of algae-type water mixed algae and indoor purely cultured algae, in particular to a portable water body phytoplankton migration rate measurement device. Background technique [0002] Eutrophication is the main problem facing lakes in China. Frequent outbreaks of cyanobacterial blooms are an important natural sign of the gradual increase in eutrophication, and it is also one of the main environmental problems in China. Cyanobacteria can adjust their own buoyancy because of their structures such as pseudovacuates. The rupture and regeneration of pseudovacidia can change the turgor pressure inside the algae cells, thereby adjusting their vertical distribution in the water body, migrating day and night, seeking a suitable water environment, and proliferating rapidly. , forming a cyanobacterial bloom. In addition, under adversity, the activity of cyanobacteria decreases and tends to sink, ...
