Description

Technical Field

[0001] The utility model belongs to the field of aquaculture equipment, in particular to an aquaculture net cage with adjustable size. Background Art

[0002] Cage culture is a method of aquaculture in which cages are placed in certain waters, such as lakes, rivers, reservoirs, and other waters with flowing water, fresh water quality, and high dissolved oxygen content. Cage culture can be carried out in high-density intensive breeding and is easy to catch. Cage culture is also beneficial for preventing other carnivorous fish and birds from harming aquatic products, which is conducive to large-scale breeding. Existing cages are usually fixed. As the farmed fish grow, the cages are often too crowded, which will affect the growth of the fish. Therefore, during the breeding process, cages with larger space will be replaced, increasing the burden on farmers. Although there are cages that can adjust the size, most of them are longitudinally adjusted. Such cages are not suitable for breeding in shallow waters. At the same time, most cages that can adjust the size use fixed motors, which are prone to leakage and trigger dangers, and are not suitable. Therefore, it is necessary to develop cages that can be adjusted horizontally and are not suitable for fixed electrical equipment to solve the above problems. Utility Model Content

[0003] In view of the above technical problems, the utility model provides an aquaculture cage with adjustable size.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an aquaculture net cage with adjustable size, comprising a main net cage, a net cage door is rotatably connected on the top surface of the main net cage, auxiliary net cages are slidably connected on both sides of the main net cage, a gear box is connected on the long edge of the top of the main net cage, an active bevel gear is rotatably connected to the gear box, and driven bevel gears are rotatably connected on both sides, the active bevel gear is meshed with the driven bevel gear, the gear box is also rotatably connected with a rotating rod and a screw rod, the active bevel gear is fixedly connected to the rotating rod, the driven bevel gear is fixedly connected to the screw rod, a first fixed block is connected to the top corner of the auxiliary net cage, a wire sleeve is connected to the first fixed block, sliding plates are fixedly connected to the top corners on both sides of the main net cage, and the wire sleeve passes through the sliding plate and is sleeved on the screw rod.

[0005] Furthermore, a sliding tube is fixedly connected to the long edge of the main net box, a second fixed plate is connected to the top corner of the auxiliary net box, a sliding rod is fixedly connected to the second fixed plate, and the sliding rod is slidably connected to the sliding tube.

[0009] Furthermore, a vertical fixing pipe is fixedly connected to the main net box, and a fixing rod is slidably connected inside the fixing pipe.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The utility model can extend auxiliary cages to both sides of the main cage, and can adjust the size of the cage as the fish grow, so that the fish will not be overcrowded. At the same time, the design of extending to both sides is suitable for shallower waters in the north.

DETAILED DESCRIPTION

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 31. An aquaculture cage with adjustable size, comprising a main cage 1, a cage door 3 is rotatably connected to the top surface of the main cage 1, auxiliary cages 2 are slidably connected on both sides of the main cage 1, a gear box 4 is connected to the long edge on the top of the main cage 1, an active bevel gear 19 is rotatably connected to the gear box 4, and driven bevel gears 20 are rotatably connected to both sides, the active bevel gear 19 is meshingly connected with the driven bevel gear 20, the gear box 4 is also rotatably connected to a rotating rod 17 and a screw rod 6, the active bevel gear 19 is fixedly connected to the rotating rod 17, the driven bevel gear 20 is fixedly connected to the screw rod 6, a first fixed block 8a is connected to the top corner of the auxiliary cage 2, a silk sleeve 8 is connected to the first fixed block 8a, sliding plates 7 are fixedly connected to the top corners on both sides of the main cage 1, the silk sleeve 8 passes through the sliding plate 7 and is sleeved on the screw rod 6.

[0019] In order to make the two auxiliary net boxes 2 extend to both sides, the thread directions of the two screw rods 6 and the thread sleeves 8 matched therewith are opposite.

[0020] In order to ensure the stability of the auxiliary net box 2 after being extended, a sliding pipe 13 is fixedly connected to the long edge of the main net box 1, a second fixed plate 10 is connected to the top corner of the auxiliary net box 2, a sliding rod 12 is fixedly connected to the second fixed plate 10, and the sliding rod 12 is slidably connected to the sliding pipe 13.

[0021] In order to prevent the auxiliary net box 2 from being damaged due to excessive extension, a slide groove 13a is provided on the slide tube 13, and the end of the slide rod 12 is connected to a limiting block 12a, and the limiting block 12a slides in the slide groove 13a.

[0022] In order to protect the rotating rod 17 , a protective tube 5 is provided on the outer cover of the rotating rod 17 . The protective tube 5 is fixedly connected to the gear box 4 . A rotating block 18 is connected to the top of the rotating rod 17 .

[0023] In order to facilitate extension, the side panels 14 of the main net box 1 and the top panel 9 of the auxiliary net box 2 are both hard mesh panels, and the side panels 11 of the auxiliary net box 2 are soft mesh cloth.

[0024] In order to facilitate fixing of the net box, a vertical fixing pipe 15 is fixedly connected to the main net box 1, and a fixing rod 16 is slidably connected inside the fixing pipe 15.

[0025] It should be noted that the length of the fixing rod 16 depends on the actual situation and can be much longer than the length of the fixing tube 15 .

[0026] The specific working process of the utility model is as follows:

[0027] During breeding, the address of cage breeding is selected, the fixing rod 16 is nailed down, and the fixing pipe 15 is sleeved thereon, the cage door 3 is opened, the fish are placed in the main cage 1, and the cage door 3 is closed and locked.

[0028] When the size of the net box needs to be adjusted, use a tool in conjunction with the clamping block 18 to rotate the rotating rod 17, so that the active bevel gear 19 in the gear box 4 rotates, driving the two driven bevel gears 20 to rotate, thereby driving the screw rod 6 to rotate, driving the wire sleeve 8 fixedly connected to the auxiliary net box 2 to move to both sides, and driving the auxiliary net box 2 to extend. During this process, the sliding plate 7 maintains the stability of the wire sleeve 8, and the sliding tube 13 and the sliding rod 12 slide in cooperation to play a supporting role, thereby maintaining the stability of the auxiliary net box 2 relative to the main net box 1; when rotated to the maximum, the limit block 12a is located at the end of the slide groove 13a to prevent the auxiliary net box 2 from falling.

[0029] During salvaging, the rotating rod 17 is rotated in the opposite direction, and the auxiliary net cage 2 is contracted through the above working process to reduce the volume of the net cage, which is convenient for salvaging.

[0030] Among them, the side panels 14 of the main net box 1 and the top panel 9 of the auxiliary net box 2 are hard mesh panels with strong impact resistance, and the side panels of the auxiliary net box 2 are soft mesh cloth to avoid unnecessary friction and damage during the extension process.

[0031] It should be noted that the salvaging process is relatively short and there is no need to consider the fish's activity space, so reducing the size of the cage will not have a bad impact.

[0032] It should be noted that the protection tube 5 is fixedly connected to prevent the water flow from impacting the rotating rod 17, and a slide groove 13a is provided on the slide tube 13 to prevent pressure from being generated to prevent the slide rod 12 from moving, while the end of the wire sleeve 8 is open.
