[0002] Marine economy generally includes the production activities for developing marine resources and relying on marine space, and the related industrial activities of directly or indirectly developing marine resources and space, and the economic collection formed by such industrial activities is regarded as the scope of modern marine economy. The mariculture industry occupies an important proportion; the mariculture net cage refers to the mariculture net cage that can be used in relatively deep sea (usually the depth of sea area is greater than 20m).

[0003] However, in the process of net cage fishing, the traditional way is to manually pull the net, and then place the net containing fish on the transport ship. In this way, a large number of manual labor is required in the process of pulling the net, which is time-consuming and laborious, and there is a risk of falling into the water for the breeding personnel.

[0004] The existing patent (publication number: CN210064980U) discloses a kind of offshore hoisting device, which replaces the traditional manual net pulling mode, thereby reducing a large amount of manual labor, making the process of hoisting fishing net cage more quickly, and saving a lot of labor, so that the process of hoisting fishing net cage is no longer time-consuming and laborious. By manually controlling the operation of the offshore hoisting device, the process of manually pulling the net is saved, so that the manual work is away from the hoisting site, avoiding the risk of falling into the water during the process of manually pulling the net, and ensuring personal safety.

[0005] However, the above technical solution still has certain defects. The above device hoists the fishing net cage to transport the fish to the ship, at which time multiple workers are required to remove the hoisting fishing net cage from the hoisting device, then pour the fish in the hoisting fishing net cage onto the ship, and then hang the hoisting fishing net cage on the hoisting device again. This is a large amount of work with complicated steps, requires more manual labor, and is time-consuming and laborious. Therefore, a hoisting assembly for mariculture net cage is proposed.

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. The embodiments described below by referring to the drawings are exemplary and are only used for explaining the utility model, and cannot be understood as limiting the utility model.

[0025] The embodiments of the utility model will be described below according to the whole structure of the utility model.

[0026] A marine culture net cage hoisting assembly, as shown in the figure, comprises a base body 100, a side frame 110 fixedly installed on the upper end of the base body 100, a fishing net 120 installed in the side frame 110, and a moving assembly 200 arranged inside the base body 100; the moving assembly 200 comprises a movable chamber 210 formed in the base body 100, first and second moving plates 220 and 230 respectively slidably connected to the two sides of the movable chamber 210, L-shaped connecting plates 240 fixedly connected to one end of each of the first and second moving plates 220 and 230, a first rack 250 fixedly connected to the first moving plate 220 through the L-shaped connecting plate 240, a second rack 260 fixedly connected to the second moving plate 230 through the L-shaped connecting plate 240, the first and second racks 250 and 260 arranged in an upper-lower relationship, and a gear 270 engaged between the first and second racks 250 and 260; a drive motor 280 is fixedly installed at one end of the movable chamber 210, and the output end of the drive motor 280 is fixedly connected to the center of one side of the gear 270.

[0027] When the staff hoist the fishing net cage to the upper side of the ship body through the hoisting machine, the drive motor 280 is started in forward rotation through the controller, the output end of the drive motor 280 drives the gear 270 to start rotating, thereby driving the first and second racks 250 and 260 engaged with the gear 270 to move relatively, and further driving the first and second moving plates 220 and 230 fixedly connected through the L-shaped connecting plates 240 to slide relatively, so as to open the lower side of the base body 100; at this time, the remaining seawater in the fishing net cage and the fish fished up fall through the lower through slot to the ship, and when the fish in the fishing net cage are cleaned, the drive motor 280 is started in reverse rotation, thereby driving the first and second moving plates 220 and 230 to move relatively close to each other until closed, which greatly improves the fish cleaning efficiency of the staff, and the device has simple structure and simple operation steps, and the staff do not need to take down and hang up the fishing net cage, thereby improving the overall fishing efficiency.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4 , the upper and lower ends of the movable chamber 210 are fixedly installed with slide rails 290, the first and second racks 250 and 260 are slidably connected to the corresponding slide rails 290, a sliding groove 2920 is formed at one end of the movable chamber 210 away from the drive motor 280, a plurality of groups of equidistantly distributed rollers 2910 are installed on the upper and lower sides of the other end of each of the first and second moving plates 220 and 230 away from the drive motor 280, and the plurality of groups of rollers 2910 are slidably connected to the sliding groove 2920.

[0029] By setting the slide rail 290, the first rack 250 and the second rack 260 and the first moving plate 220 and the second moving plate 230 are more stable, and the smaller first moving plate 220 and the second moving plate 230 are connected with the base body 100 through a plurality of groups of equidistantly distributed rollers 2910 and slide grooves 2920, and the friction between the first moving plate 220 and the second moving plate 230 and the base body 100 is further improved.

[0031] The four steel balls 130 are made of stainless steel, so the weight is relatively large, when the fishing net cage enters the seawater, the weight of the four steel balls 130 assists the sinking of the whole device, and the hanging ring 140 fixedly installed at the four corners of the top of the side frame 110 makes the fishing net cage be lifted relatively uniformly and not easy to shake.

[0032] Please refer to Figure 1 As shown, the side frame 110 is arranged in a structure of wide at the top and narrow at the bottom.

[0033] By arranging the side frame 110 in a structure of wide at the top and narrow at the bottom, the device can salvage more fish at one time, thereby improving the fishing efficiency of the operator.

[0034] In use, the controller starts the driving motor 280 to rotate forward, the output end of the driving motor 280 drives the gear 270 to start rotating, thereby driving the first rack 250 and the second rack 260 engaged with the gear 270 to move relatively, and further driving the first moving plate 220 and the second moving plate 230 fixedly connected through the L-shaped connecting plate 240 to slide relatively, opening the bottom of the base body 100, at this time, the remaining seawater in the fishing net cage and the fish salvaged from the bottom through the slot fall onto the ship, when the fish in the fishing net cage is cleaned, the driving motor 280 is started to reverse, thereby driving the first moving plate 220 and the second moving plate 230 to move relatively close, until closed, greatly improving the efficiency of the operator to empty the fish, and the device is simple in structure and simple in operation steps, without the need for the operator to take down the fishing net cage and hang it up, improving the overall fishing efficiency, the parts not involved in the device are the same as or can be realized by the existing technology.

[0035] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, and the person skilled in the art can make the modification, replacement and change of the embodiments without the creative contribution after reading the specification without departing from the principles and the purpose of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
