Problems solved by technology

[0003] The culture net cage is mainly composed of the floating frame of the net cage and the net clothes suspended on the frame. It is convenient to catch, or the nets need to be put away when repairing, cleaning, or changing the nets. This process often requires manual operation. To gradually lift the heavy nets out of the water and tie them up requires the cooperation of at least two people. And when faced with large deep-water cages, the nets sink into the water to a depth of up to 30 meters, requiring the cooperation of multiple people to put the nets away, and it takes a lot of time

Embodiment 1

[0040] Such as figure 1 with figure 2 As shown, the portable net-cage netting device of the present invention is a mechanical device specially used to lift the net-cloth hanging into the water to the surface of the water.

[0041] In use, the netting device gradually rolls up the netting to the surface of the water, and then is tied up by the operator to gradually retract the front netting.

[0042] And this kind of netting netting device is a portable design, which can be carried, installed, and manipulated by one person. Part of the net cage netting or the entire net cage netting can be stowed according to actual needs. It can also be operated by multiple people without one. Netting a net cage.

[0043] The portable net-cage netting device includes: a winding unit, including a roller 3 for winding the net-cage net, and a driving unit for driving the roller 3 of the winding unit to rotate. The netting device also includes: a barb unit 4 arranged on the roller shaft 3 for hooking t...

Embodiment 2

[0068] For a large net cage to carry out the overall net lifting work, according to the size of the net cage, in a week, at a certain interval, hang multiple netting netting devices to simultaneously raise the net. Take a net cage with a diameter of 20 meters as an example, its circumference is 62.8 meters, and 6 netting devices can be hung.

[0069] Hang the netting device at a predetermined position, and connect its waterproof low-speed motor 5 to the 28V electric frequency on the work boat. Put the netting near the water surface on the roller 3, supply power to the netting device, start the netting device, the roller 3 will rotate upwards, and start to lift the netting hooked on the roller 3 upwards. During the lifting process, When the net clothing is blocked by the anti-overwinding steel chain at the upper end of the roller shaft 3, it will be separated from the roller shaft 3, and the overall net clothing will be continuously raised and gathered at the lower frame. The net...

Abstract

The invention relates to a portable net hauling device of a net cage and netting, and belongs to the technical field of mechanical devices for wringing nets on board. The device solves the problems that the existing net wringing device is not beneficial to carry and the efficiency is low. The device comprises a furl unit, a drive unit and an anti-roll unit, wherein the anti-roll unit is used for preventing the netting from passing by the top end of a roll shaft during the lifting process of the netting. A hook unit is arranged on the roll shaft and used for hooking the netting, and the hook unit arranged on the roll shaft rotates upwardly to drive the netting ascend upwardly. The device further comprises a frame main body, wherein the frame main body comprises a hanging unit, a cross tube unit, and a pendent unit, wherein the hanging unit is arranged on the upper portion of the frame main body and bending back downward; the cross tube unit is arranged on the middle portion of the frame main body and welded horizontally to the lower portion of the hanging unit; and the pendent unit is arranged on the lower portion of the frame main body. The portable net hauling device of the net cage and the netting has the advantages of being compact and novel in structure, low in processing cost, convenient to carry, easy to popularize, and being capable of greatly improving the net hauling efficiency of the net cage, and also having the unexpected excellent effect in net hauling of the net cage in the deep water area.

Description

Technical field [0001] The invention relates to a portable net box netting device for netting, belonging to the technical field of mechanical devices for twisting nets on ships. Background technique [0002] In recent years, sea cage aquaculture has developed rapidly. A large number of large-scale deep-water cage aquaculture projects have emerged in coastal areas. In some large domestic reservoirs, such as Liujiaxia Reservoir and Longyangxia Reservoir, there are also large-scale cage aquaculture projects. During the process of cage culture, the size of individual cages gradually increased, and large-scale wind and wave-resistant deep-water net cages with a diameter of up to 50 meters have appeared. The traditional maintenance of human resources has become the era of operating cages. At the same time, the technical equipment for supporting cage aquaculture has developed rapidly, especially for the equipment required for the maintenance and operation of large-scale cages. [0003] T...
