Description

A seagrass transplanting device for divers

technical field

The invention relates to a seaweed transplanting device, in particular to a seaweed transplanting device for divers, which is suitable for divers to carry and is convenient for taking and placing seaweed and nails for seaweed transplantation.

Background technique

Seagrass is the only higher plant in the ocean. It can not only directly provide high primary productivity, but also serve as the attachment base for other epiphytic algae and other marine animals to lay eggs, which is of great significance to the ecological environment of coastal marine fisheries. . Eelgrass seagrass is the dominant species of seagrass in the northern hemisphere, and it is also the most important and widely distributed seagrass species in northern my country. The eelgrass seagrass farm used to be one of the most important ecosystems in northern my country, especially the Shandong Peninsula, and it was the spawning ground, feeding ground and nursery ground for many important economic fishes. However, with the continuous development of my country's coastal zone, many seagrass farms in coastal waters have been reclamated or polluted, resulting in the disappearance of a large number of seagrass farms, which not only further deteriorates the coastal water environment, but also seriously declines fishery resources. Therefore, it is of great significance to restore the ecological environment of seagrass farms that have been destroyed, to restore the ecological environment of my country's coastal fishery and to restore the sustainable utilization of my country's fishery resources.

The decline of seagrass land is a problem faced by many countries in the world. At present, some developed marine countries in the world have carried out research work on seagrass restoration very early, and have achieved good results. In recent years, my country has also begun to pay attention to the restoration of the ecological environment of coastal fishery waters. Among them, the National Natural Science Foundation of China, the Oceanic Public Welfare Project of the State Oceanic Administration, and the Ministry of Agriculture's public welfare projects all include the restoration of seagrass farms. At present, the method of using seeds for propagation is still in the experimental stage, and the restoration of sea grasslands in the world mainly adopts transplantation. The most important method of transplanting eelgrass seaweed is to use manual operation by divers, and the key problem facing manual transplantation is to reduce costs and improve transplantation efficiency. The most commonly used method of transplanting eelgrass seaweed is the nail method, by using the fixing effect of the nails, each seaweed is fixed on the seabed. Thereby the diver needs to hold a nail in one hand and the seaweed plant in the other to operate during the operation. Seaweed is often placed in a net bag carried by a diver, and the net bag generally floats above the diver's body because the seaweed therein is lighter. And in order to prevent the loss of seaweed, it is necessary to tie the mouth of the net tightly with a rope and fix it on the diver. Every time a plant of seaweed is transplanted, it must be taken from the net bag once. This process includes pulling down the net bag from the top of the body, and then opening the tightened net Take seaweed and plant it. This action is relatively easy on land, but for divers in water, it often takes a certain amount of time. And because the rope of net bag may be wound on diving equipment, has reduced the efficiency of diver's transplanting seaweed, may even have influence on diver's personal safety. Therefore develop a kind of seagrass transplanting device that divers use, for shortening the time that divers pick and place seaweed, improve the efficiency of seagrass transplantation very key.

Put seaweed.

When divers transplant seaweed on the seabed, in order to avoid disturbing the sediment on the seabed and causing the water to become turbid, they need to keep their bodies close to the seabed but not in contact with the seabed. When traditional net bags are used to store seaweed, the ropes of the net bags may become entangled with the trachea and instruments of the diver's diving equipment, which not only affects the work efficiency, but even turns the body to untangle the entanglement, which will stir the water body and cause the seabed Suspended sediment reduces visibility. Moreover, the buoyancy of the seaweed will tighten the mouth of the net bag, and each time the seaweed needs to be opened with both hands, it takes a lot of time. When using the present invention to plant seaweed, the nails can be removed from the elastic rope 6 first, and then the seaweed plants can be extracted. Only one hand can complete the operation of removing the nails and seaweed, which greatly improves the efficiency of seaweed transplantation.
