A sinking and floating balancing device for aquaculture net cages

Abstract

This utility model relates to the field of aquaculture cage technology, and in particular to a sinking and balancing device for aquaculture cages. The device includes a cage body, which comprises a support ring, a support rod, and a cage mesh. A rotating shaft is rotatably mounted on the outer wall of the support rod, and a hanging rod is fixedly connected to the outer wall of the rotating shaft. A settling component is installed at the lower end of the hanging rod. When it is necessary to replace the settling blocks to maintain the balance of the aquaculture cage, the device uses a float to pull the traction rope, causing the hanging rod to rotate upwards and become vertical. This rotates the cage containing the settling blocks above the water surface, allowing personnel to replace the settling blocks without entering the water, making adjustments more convenient and faster. Simultaneously, a locking plate, in conjunction with a locking plate, positions the traction rope, keeping the rotating and inverted hanging rod vertical. This eliminates the need for manual intervention, further facilitating the replacement of the settling blocks.

Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, and in particular to a sinking and buoyancy balancing device for aquaculture cages. Background Technology

[0002] The existing aquaculture cages have overly simple structures, often using simple foam ball structures or hard plastic ball structures. This simple structure makes it difficult to maintain the balance of the device during its sinking and floating, and poor balance can easily lead to the aquaculture cages tipping over.

[0003] A current patent, CN213369411U, discloses a floating and balancing device for aquaculture net cages. The device includes a net cage body and a floating and balancing system structure. The net cage body consists of upper and lower support rings, support longitudinal rods, and netting. The support longitudinal rods and the upper and lower support rings are all lined with and fixed with netting. The floating and balancing system structure consists of a clamping head, a horizontal column, a longitudinal suspension rod, a floating and balancing hemisphere, a bottom cover, and a sinking block. The horizontal column and the longitudinal suspension rod are rotatably connected. A floating and balancing hemisphere is located at the bottom of the longitudinal suspension rod. A bottom cover is installed at the bottom of the floating and balancing hemisphere, and the bottom cover has an annular protrusion wall. A fixing protrusion is provided on the bottom cover, and a sinking block is engaged with the fixing protrusion. The bottom of the floating and balancing hemisphere has a detachable bottom cover, and a sinking block with adjustable weight is installed inside the floating and balancing hemisphere.

[0004] The aforementioned device allows for adjustment of the type of settling blocks as needed, and can be disassembled and replaced when problems arise in the hemispherical system, enabling better adjustment of the aquaculture cage's balance. However, since the hemispherical system is submerged below the cage during adaptation, it is not convenient to adjust the type of settling blocks within the hemispherical system on the water surface. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of adjusting the size of the settling blocks on the water surface, and to propose a buoyancy balancing device for aquaculture net cages.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a floating and balancing device for aquaculture cages, including a cage body, the cage body including a support ring, a support rod and a cage net, a rotating shaft rotatably mounted on the outer wall of the support rod, a hanging rod fixedly connected to the outer wall of the rotating shaft, and a sinking component installed at the lower end of the hanging rod; A drive plate is slidably mounted on the outer wall of the support rod. The outer wall of the drive plate is connected to a rotating shaft through a transmission assembly. A traction assembly is mounted on the upper end of the drive plate.

[0007] Furthermore, a guide groove is provided on the side of the drive plate, and a guide rail is slidably installed inside the guide groove. A support rod is fixedly connected to the side of the guide rail.

[0008] Furthermore, the settling assembly includes a box body fixedly installed at the lower end of the boom, the interior of the box body is used to place the settling block, and the lower end of the box body is fixedly connected to a sealing cover by fasteners.

[0009] Furthermore, the transmission assembly includes a gear fixedly mounted on one end of the rotating shaft, and a rack located outside the gear is fixedly mounted on the side of the drive plate, the rack meshing with the gear.

[0010] Furthermore, the traction assembly includes a traction rope fixedly installed on the upper end of the drive plate, a plurality of clamping plates fixedly installed on the outer wall of the traction rope, a positioning ring sleeved on the outer wall of the traction rope, and an upper support ring fixedly connected to the bottom of the positioning ring. The positioning ring has a pair of slots on its inner wall, and a snap-fit ​​plate is slidably installed inside the slots via a pop-out component.

[0011] Furthermore, the pop-out component includes a groove formed on the top of the positioning ring, a toggle plate is slidably installed inside the groove, a spring piece is fixedly connected to the outside of the toggle plate, and the end of the spring piece away from the toggle plate abuts against the inner wall of the groove.

[0012] The present invention proposes a floating and balancing device for aquaculture net cages, which has the following advantages: When it is necessary to replace the settling blocks to maintain the balance of the aquaculture net cage, the device can rotate the boom upwards and vertically by pulling the traction rope with the float, thereby rotating the box used to hold the settling blocks above the water surface so that personnel can replace the settling blocks on the water surface without entering the water, making the adjustment more convenient and quick. At the same time, the traction rope is positioned by the locking plate, so that the rotating and inverted boom remains vertical, and the boom can be fixed without manual intervention, further facilitating the replacement of the settling blocks.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 As an embodiment of this utility model, a sinking and floating balancing device for aquaculture net cages is disclosed, including a cage body 1. The cage body 1 includes a support ring 11, a support rod 12 and a cage net 13. A rotating shaft 3 is rotatably installed on the outer wall of the support rod 12. A hanging rod 4 is fixedly connected to the outer wall of the rotating shaft 3. A sinking component 5 is installed at the lower end of the hanging rod 4. Settling blocks are installed inside settling assembly 5, and settling assembly 5 is connected to box 1 as a whole by means of hanging rod 4, increasing the weight of the entire aquaculture net cage. The balance of the aquaculture net cage is adjusted by adjusting the model of the settling blocks in each settling assembly 5. Among them, a drive plate 6 is slidably installed on the outer wall of the support rod 12, the outer wall of the drive plate 6 is connected to the rotating shaft 3 through the transmission assembly 7, and a traction assembly 8 is installed on the upper end of the drive plate 6; By pulling the drive plate 6 upward by the traction component 8, the upward-moving drive plate 6 drives the rotating shaft 3 to rotate through the transmission component 7, and drives the lifting rod 4 to rotate upward, so that the settling component 5 rotates above the upper support ring 11, thereby facilitating the disassembly and assembly of the settling component 5 located above the water surface to replace its internal settling block.

[0017] In some embodiments, a guide groove 61 is provided on the side of the drive plate 6, and a guide rail 62 is slidably installed inside the guide groove 61. A support rod 12 is fixedly connected to the side of the guide rail 62. The drive plate 6 is guided by the guide rail 62 and the guide groove 61 so that it can only slide up and down on the side of the support rod 12.

[0018] For example, the settling assembly 5 includes a box 51 fixedly installed at the lower end of the boom 4. The inside of the box 51 is used to place the settling block. The lower end of the box 51 is fixedly connected to a sealing cover 52 by a fastener. Preferably, the fastener is a screw, and the lower end of the screw passes through the sealing cover 52 and is threaded to the box 51. When the boom 4 is rotated upwards and inverted, causing the settling assembly 5 to rise above the water surface, the box 51 is inverted, thereby unscrewing the screws to remove the sealing cover 52, removing the old settling block inside the box 51, replacing it with a different model of settling block, and then tightening the screws on the sealing cover 52.

[0019] It should be noted that the transmission assembly 7 includes a gear 71 fixedly installed on one end of the rotating shaft 3, and a rack 72 located outside the gear 71 is fixedly installed on the side of the drive plate 6, and the rack 72 meshes with the gear 71. When the drive plate 6 rises, it drives the rack 72 to move upward and drives the gear 71 and the rotating shaft 3 to rotate, thereby causing the rotating shaft 3 to drive the boom 4 to rotate upward.

[0020] Furthermore, the traction assembly 8 includes a traction rope 81 fixedly installed on the upper end of the drive plate 6. Several clamping plates 82 are fixedly installed on the outer wall of the traction rope 81. A positioning ring 83 is sleeved on the outer wall of the traction rope 81. The bottom of the positioning ring 83 is fixedly connected to the upper support ring 11. Preferably, a float is fixedly connected to the upper end of the traction rope 81. The positioning ring 83 has a pair of slots 84 on its inner wall. A snap-fit ​​plate 85 is slidably installed inside the slots 84 through the pop-out component 9. The bottom of the snap-fit ​​plate 85 has a chamfer located inside the positioning ring 83. The float pulls the traction rope 81, causing the drive plate 6 to move upward. At the same time, several clamping plates 82 rise and enter the positioning ring 83. The clamping plates 82, upon entering the positioning ring 83, first squeeze the chamfer at the bottom of the clamping plate 85, causing the clamping plate 85 to retract into the slot 84. After the clamping plates 82 rise above the slot 84, the two clamping plates 85 are ejected by the ejection component 9 and clamp the traction rope 81, locking between the two adjacent clamping plates 82, thus locking the upper clamping plate 82 and preventing it from descending.

[0021] Furthermore, the pop-out component 9 includes a groove 91 formed on the top of the positioning ring 83. A toggle plate 92 is slidably installed inside the groove 91. A spring piece 93 is fixedly connected to the outside of the toggle plate 92. The end of the spring piece 93 away from the toggle plate 92 abuts against the inner wall of the groove 91. The spring plate 93 pushes the actuating plate 92 to move within the slide groove 91, causing a pair of snap-fit ​​plates 85 to approach and pop out of the slot 84 to insert into the positioning ring 83. The actuating plate 92 pushes the snap-fit ​​plates 85 outward to retract them into the slot 84, thereby releasing the snap-fit ​​on the snap-fit ​​plates 82 and allowing the traction rope 81 to descend.

[0022] Working method: When it is necessary to replace the settling block to adjust the balance of the aquaculture net cage, the traction rope 81 is pulled up by the float, which drives the drive plate 6 to move upward. When the drive plate 6 rises, it drives the rack 72 to move upward and drives the gear 71 and the rotating shaft 3 to rotate, which in turn drives the hanging rod 4 to rotate upward. When the boom 4 is rotated upward and inverted, causing the box 51 to rise above the water surface and invert, the spring 93 pushes a pair of snap-fit ​​plates 85 to insert into the positioning ring 83, so that the pair of snap-fit ​​plates 85 are inserted between two adjacent snap-fit ​​plates 82, thereby locking the upper snap-fit ​​plate 82 and preventing it from descending. This prevents the drive plate 6 from moving down, and the boom 4 cannot rotate outward and is blocked by the support rod 12 from rotating inward, thus remaining vertical. Unscrew the screws to remove the sealing cover 52, remove the old settling block inside the box 51, replace it with a different model of orange block, and then put the sealing cover 52 back on and tighten the screws. By moving a pair of actuating plates 92 outward, a pair of locking plates 85 are moved outward, thereby releasing the restriction on the locking plate 82 above the locking plate 85, allowing the traction rope 81 and drive plate 6 to rise and fall freely, releasing the restriction on the rotating shaft 3, and causing the boom 4 to rotate outward and downward under the action of weight, so that the box 51 is submerged underwater again.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
