Embodiment Construction

[0014] Such as Figure 1 to Figure 5 Shown, a kind of cage fishing device that can be lifted freely comprises net bag 8, outer frame 9, inner bracket 10, lifting device and opening and closing device; 9 plays the role of fixing and connecting each component and maintaining stability. The internal bracket 10 is used to support the net bag 8 and the opening and closing device. The opening and closing device is used to control the opening and closing of the net bag 8. The net bag 8 is linked with the opening and closing device For catching fish, the lifting device installed on the outer frame 9 is used to pull the lifting of the inner bracket 10 to complete the fishing action. The net bag 8 is closed when fishing, and is separated in other periods.

[0015] Described inner bracket 10 is made up of annular buoyancy tube two 5 and the cross steel frame 6 that is fixed in annular buoyancy tube two 5. Provide structural strength for net bag 8 and opening and closing device.

Abstract

The invention discloses a net cage fishing device capable of freely lifting, and belongs to the technical field of aquaculture net cage fishing devices. According to the culture equipment, cultured fishes in a net cage can be catched through opening, closing and lifting. The net cage fishing device is characterized in that an inner bracket is arranged in an outer frame in a spaced mode, the outerframe plays a role in fixing and connecting all the components and keeping the components stable, a lifting device installed on the outer frame is used for pulling the inner bracket to ascend and descend so as to complete the fishing action, the inner bracket is used for supporting a net bag and an opening and closing device, the opening and closing device is used for controlling opening and closing of the net bag, the net bag is linked with the opening and closing device for catching fish schools, and the net bag is closed during fishing and is separated in other time periods. According to the net cage fishing device, through cooperation of the opening and closing device and the lifting device, the automatic fishing function and the free lifting function are achieved, the functions are diverse, the using effect is good, the net cage fishing device can be additionally arranged on the basis of the net cage, and the fishing work of different fishes is met; and through lifting opening andclosing of the mechanism, continuous operation can be conducted, and other functions of the net cage are not affected.

Description

technical field [0001] The invention belongs to the technical field of net cage fishing devices for aquaculture, and in particular relates to a freely lifting net cage fishing device. Background technique [0002] Cages are widely used as a new type of high-efficiency aquaculture equipment. However, general cages have a single structure and simple functions, and do not have the function of self-fishing. Contents of the invention [0003] The object of the present invention is to provide a culture equipment that can catch cultured fish in a net cage by opening, closing and lifting. [0004] The technical solution adopted by the present invention is: a freely lifting net cage fishing device, including a net bag, an external frame, an internal bracket, a lifting device and an opening and closing device; the gap between the internal brackets is arranged in the external frame, and the external The frame plays the role of fixing, connecting each component and maintaining stabil...
