Problems solved by technology

However, the larger the net cage, the more difficult it is to replace the net clothing. The existing net clothing is a single-layer net structure, the mesh reinforcement is not properly set, the overall structural strength of the net clothing is not strong enough, and the service life is short, which is not conducive to the safety of breeding.

Embodiment 1

[0030] Such as Figure 1-9As shown, the fan-shaped breeding net clothing includes the net clothing 7 connected to the cage frame 1, the cage frame 1 axis is provided with a floating column 5, and the upper and lower ends of the floating column 5 are evenly distributed with sliding rings 6, and the sliding ring 6 The floating bridge 2 is connected with the net cage frame 1 through the floating bridge 2, the floating bridge 2 at the upper and lower ends is connected through the balance connecting rod 3, the inner and outer sides and the bottom of the net cage frame 1 are connected with net clothes 7, and the corresponding floating bridge 2 sides at the upper and lower ends are connected with net clothes 7. The inner wall of the net cage frame 1 is provided with a chute corresponding to the pontoon 2, and the surface of the chute is provided with fixing holes, and both sides of the contact end of the pontoon 2 and the chute are provided with a movable fixed curved plate 201, and t...

Embodiment 2

[0036] Such as Figure 1-9 As shown, the cultivators can fix the fixed curved plate 201 after rotating the pontoon 2, and then divide the internal space of the cultivating cage of the present invention according to the cultivating requirements, and cultivate fish with different space requirements in different separated spaces without much effort. And the flexibility is high, by rationally distributing the culture space, it is beneficial to improve the culture yield of fish, and the survival rate of juvenile fish can be improved by separating the large and small fish, and the net opening closing mechanism 4 can be arranged on the side of the net clothes connected up and down on the pontoon bridge 2, and Corresponding network ports are set to realize the cultivation of fish of different specifications in different breeding areas in the cages. The breeding cages can be connected through cylindrical cages to realize the combination of breeding areas, and 4 pairs of network port clo...

Embodiment 3

[0038] Select 10 folding culture net cages of the present invention (experimental group) and 10 markets to buy the culture net cages (control group) of the same capacity, carry out culture experiment in a certain farm in Dinghai District, Zhoushan, when 3~4 months, above-mentioned 20 cages were put into use, and 800 female broodstock (more than 600 g / tail) and 400 male broodstock (more than 400 g / tail) were put into the experimental group and the control group respectively. The above-mentioned fish species were large yellow croakers, which were cultivated in spring When the water temperature of broodstock is below 14°C, feed the feed once every 1-2 days, and the feeding rate is 1-2%. 3~6%, culture one year, in the breeding process again, the experimental group divides the net cage culture space by the mode of embodiment 2, and the control group is cultured by the conventional culture mode, and in the one year culture process, the maintenance of the net cage is all by routine ma...

Abstract

The invention discloses a fan-shaped culture netting, belonging to the technical field of culture equipment. The fan-shaped culture netting comprises nettings connected on a net cage frame, wherein afloating column is arranged at the axial center of the net cage frame, sliding rings are uniformly distributed at the upper end and the lower end of the floating column, the sliding rings are connected with the net cage frame through floating bridges, the floating bridges at the upper end and the lower end are connected with each other through a balance connecting rod, the nettings are connected with the inner side, the outer side and the bottom of the net cage frame, and the two side surfaces of the floating bridges corresponding to the upper end and the lower end are connected with nettings.The netting provided by the invention is woven with composite ropes which have high toughness, strength and corrosion resistance, pollutants are not easy to adhere, and a net cage provided with the netting has strong wind wave resistance, and is good in anti-fouling effect and high in breeding yield.

Description

technical field [0001] The invention belongs to the technical field of breeding equipment, in particular to a fan-shaped breeding net. Background technique [0002] Breeding net clothing is an indispensable and important material for seawater fish seine or cage culture, and its performance is directly related to the success or failure of seawater fish culture. Fiber is one of the main materials for the production of aquaculture nets in the field of seawater fish farming technology. It is directly related to the performance of aquaculture nets, the consumption of raw materials for aquaculture nets, and the safety of seawater fish aquaculture facilities. The fiber is processed with a single high-density polyethylene resin as raw material by hot water drawing process. Due to improper control of the drawing process, the nodule strength is relatively low, which will further affect the performance of breeding nets, the consumption of raw materials for breeding nets and seawater. ...
