Abstract

The invention discloses a support device for a plankton net. The support device comprises a plurality of support rods, wherein hangers are arranged on the support rods and are provided with connection parts connected with the support rods; the connection parts are connected with hanger heads by connection sheets; connection pins which are arranged in pair are arranged on the support rods; the connection hinges are hinged with a connection cross rod; a mounting hole which extends along an axis of the connection cross rod is formed at the hinged position which is away from the connection pins on the connection cross rod; the adjacent support rods pass through the connection cross rod, a bolt for passing through the mounting hole in the connection cross rod and a fastening nut for fastening the bolt; the fastening nut comprises a tightening part with threads and a wing part fixedly connected with the tightening part; a run-through incoming line groove is formed on the wing part; and a plurality of line clamping grooves are communicated with the incoming line groove. By the support device, the plankton acquisition net is fixed relatively integrally, so compared with the conventional mode of being hung at one position singly, the plankton acquisition net is more stable, and the plankton acquisition operation can be completed by one person.

Description

technical field [0001] The invention relates to a support device, in particular to a support device for fixing plankton nets. Background technique [0002] In the investigation and research of aquatic biological resources, the collection of plankton is an indispensable work. Generally, two people need to work together to collect plankton. One person collects water with a water collector, and the other is responsible for filtering with a plankton net. , its structure includes a collection circle and a net cover fixed on the collection circle. Plankton enters the collection net through the mouth of the collection circle. The existing collection net still has problems such as relatively large swings when the wind and waves are slightly large, which cannot meet the requirements. Requirements. Moreover, when there are insufficient personnel, or only one person can perform the sampling work, the sampling work is difficult to complete. The collection of plankton often needs to go...
