Ecological culture net cage capable of automatically sinking and floating to keep balance

Abstract

The invention relates to an ecological culture net cage capable of automatically sinking and floating to keep balance and relates to a culture net cage in the field of seawater culture equipment. The ecological culture net cage comprises a net cage frame which consists of buoyancy vertical pipes, top connecting pipes, bottom upper connecting pipes, bottom lower connecting pipes, internal tie bar pipes and ground anchors; a net cage sinking and floating system which consists of communicated air pipes, a head air pipe, air inlets / outlets and water inlets / outlets; and a net which consists of a top net, a bottom net, side nets and net ribs. The sinking and floating system is an automatic-balanced net cage sinking and floating system consisting of the buoyancy vertical pipes and air inlet / outlet valves and water inlet / outlet valves in the buoyancy vertical pipes, can realize the automatic-balanced sinking and floating of the net cage, is stable to be lifted up and lowered down and can prevent the net cage from getting turned upside down during sinking and floating. Since sea cucumber anti-wind and anti-wave adhering bases are arranged in the net, when heavy-wind and heavy-wave ocean currents are encountered, sea cucumbers can enter the adhering bases for inhabitation. Since a dual-layer net with a black inner layer and a light green outer layer is arranged and the internal part of the net is dark green, the net is particularly suitable for the growth habit of the sea cucumbers. The net cage has the advantages that the cultured sea cucumbers grow vigorously, the yield is high, the economic income of fishermen is good and the social benefit is remarkable.

Description

Technical field: [0001] The invention relates to seawater aquaculture equipment, and mainly relates to aquaculture net cages. Background technique: [0002] At present, my country's sea cucumber cage culture has gradually developed to 20-30 meters deeper sea waters, and has been successful, and has initially successfully developed sinkable sea cucumber culture cages suitable for use in deeper sea waters, but , the existing sunk-floating sea cucumber culture net cage does not possess the self-balancing ups and downs function, and it is relatively difficult to manually operate in its ups and downs process, and improper operation also easily causes the net cage to tip over. Moreover, the nets of the existing culture net cages have insufficient overall structural strength and short service life; the net cages lack shelters for sea cucumbers to shelter from wind and waves, and there is no need to establish a shelter for sea cucumbers in the deep open sea environment of large winds...

[0002] At present, my country's sea cucumber cage culture has gradually developed to 20-30 meters deeper waters, and has been successful, and has initially successfully developed a sinkable sea cucumber culture cage suitable for use in deeper waters, but , the existing sinkable sea cucumber culture net cages do not have the function of self-balancing sinking and floating, and it is difficult to rely on manual operation in the sinking and floating process, and improper operation may easily cause the cage to tip over

Moreover, the nets of the existing culture net cages have insufficient overall structural strength and short service life; the net cages lack shelters for sea cucumbers to shelter from wind and waves, and there is no need to establish a shelter for sea cucumbers in the deep open sea environment of large winds, waves and sea currents.
