Embodiment 1

[0052] Embodiment 1: see Figure 1-Figure 4 , a lifting type net cage, the lifting type net cage includes: at least one floating tube 1 as the floating body of the lifting type net cage, 3 floating tubes are provided in this embodiment, namely the middle floating tube, the inner floating tube and the outer side Floating tubes, three floating tubes are arranged in parallel to surround a circular breeding space. According to the needs, it can also be set as two floating tubes, one floating tube or even multiple floating tubes, and can also be surrounded by triangle, square or octagonal breeding. space.

[0053] There are multiple floating pipe connectors on the floating pipe, in order to fix the floating pipe into one;

[0054] A plurality of handrail frames 4 are placed on the top of the floating pipe connector and placed inwardly;

[0055] at least one handrail tube mounted on the handrail frame, bent into a circle;

[0056] At least one set of net 3 is installed on the han...

Embodiment 2

[0073] Example 2: see Figure 11 , the hub in this technical solution is set as a cylindrical hub 6, the top and bottom of the cylindrical structure are provided with valves, when initially set, the buoyancy of the sinker 7 is greater than the buoyancy of the hub, and the hub set as this structure can be faster Realize the rise and fall of the net cage. The floating pipe in this technical solution is provided with one, two or three. When it is set to one, the rise and fall of the entire net cage is controlled by the valve on the hub. When three floating pipes are used, the hub and the valves on the floating pipes can be adjusted simultaneously, the rising and falling speed of the whole net cage is faster, and the adjustment is more convenient. All the other structures and advantages are exactly the same as those in Embodiment 1.

[0074] The main design principles of this technical solution are as follows:

[0075] When floating, the buoyancy of (outer tube + middle tube + in...

Embodiment 3

[0080] Embodiment 3: see Figure 7 , the valve includes a control valve, a spool and a valve base 1.2, wherein the spool includes a spool body and a spool base 7.2 arranged at the bottom of the spool body, the spool body is provided with a spool thread 7.1, and the upper end is set There is a spool port 7.3, and the valve is formed by wrapping the spool base with liquid plastic. The spool port is used for air in and out, and water in and out. There are threads on each spool to install the valve control valve and control the opening and closing of the valve. The bottom of the spool is the spool base. When the liquid plastic passes through the valve When the mold is poured, it can be connected into a whole, and it will be very firm after cooling. Figure 8A It is the plan view of the valve mold. From the picture, we can see that the valve mold is composed of upper and lower parts. The middle part is a circle, which can put the floating tube in. In the upper part of the valve mo...

Abstract

The present invention discloses a lifting net cage comprising: at least one floating tube as a floating body of the lifting net cage, a plurality of floating tube connecting members to fixedly integrate the floating tubes into one body; a plurality of armrest frames arranged over the floating tube connecting members and placed inwards; at least one armrest tube mounted on the armrest frame and bent into a circle; at least one sleeve net mounted on the armrest tubes, the armrest frames or the floating tube connecting members and defining a breeding space; at least one net underframe under the lifting net cages a the base of the net; a plurality of chains or ropes for connecting the floating tube connecting members to the net underframe, the net underframe to a hub, the hub to a sinker, and the sinker to an anchor; at least one sinker under the net underframe as effective pull force of the lifting net cage; at least one anchor at the seabed to keep the net cage not following the flow of water; the floating tube is provided with an adjusting assembly used to adjust the sinking and floating of the net cage.

Description

technical field [0001] The invention relates to a lift-type net cage, which is mainly used for raising fish in water and belongs to the field of plastic lift-type net cages. Background technique [0002] China is a country prone to typhoons. There are more than 30 typhoons entering the country every year. Every time a typhoon passes through the border, it has caused great losses to the farmers. The cages are broken and the fish are dead. Whether it is for offshore farming Fish rafts or deep-water cages that have become increasingly popular in recent years are all facing the threat of typhoons. Although domestic cage manufacturers have continuously improved the cages to greatly improve their anti-wind and wave capabilities, they still cannot reach the state where typhoons pass through without damage. Moreover, the strong winds, waves and short-term heavy rainfall brought by typhoons will make the fish unbearable, so farmers urgently need a product that can solve the problem o...
