Wind- and wave-preventing alga seedling culture device

Abstract

The invention discloses a wind- and wave-preventing alga seedling culture device and aims to overcome the defect that alga seedling survival rate is lowered due to the fact that alga seedlings are easily impacted by sea waves during culture. The wind- and wave-preventing alga seedling culture device comprises a transparent and vertically-through protecting cylinder, a transparent and vertically-through rotary cylinder and a positioning weight block and is characterized in that a support is connected into the protecting cylinder, an alga culture medium is connected onto the support, the rotarycylinder is rotatably mounted in the protecting cylinder, protecting cylinder and the rotary cylinder are provided with light-permeable notches facing the alga culture medium, the two light-permeablenotches are correspondingly arranged and are staggered through the rotation of the rotary cylinder, a swing rod is connected between the support and the positioning weight block, the protecting cylinder is suspended in water, a plurality of slide rods which can slide radially are evenly distributed below the support on the inner wall of the protecting cylinder and provided with racks, pinions coordinated with the racks are mounted in the protecting cylinder, inner toothed rings driven by the pinions to rotate are arranged on the inner wall of the rotary cylinder, the ends, close to the swing rod, of the slide rods are connected with arc-shaped push blocks, the swing rod is arranged among the arc-shaped push blocks, and reset springs are mounted between the other ends of the slide rods andthe protecting cylinder.

Description

technical field [0001] The invention relates to algae cultivation technology, more specifically, it relates to a device for cultivating young algae against wind and waves. Background technique [0002] Seaweeds are algae that grow in the sea and are cryptogamous plants in the plant kingdom. Algae include several different types of organisms that generate energy through photosynthesis. They are generally considered to be simple plants, and the main features are: no vascular tissue, no real differentiation of roots, stems, and leaves; no flowering, no fruits and seeds; no specialized protective tissues for reproductive organs, often directly formed by a single The cells produce spores or gametes. At present, seaweed needs to be artificially cultivated in many cases. When seaweed is cultivated in seawater, it is easily destroyed when encountering large waves. Since the root system of seaweed seedlings is not fully formed, the impact of sea waves will greatly reduce the surviva...

AI Technical Summary

Problems solved by technology

[0003] The invention overcomes the shortcoming that the young algae are easily impacted by sea waves and reduces the survival rate during the cultivation process, and provides a wind and wave proof young algae cultivation device, which has a good protection effect on the young algae, and the impact damage of the young algae by sea waves The force is greatly reduced, which is beneficial to improve the survival rate of young algae
