Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture, and more specifically, to a multifunctional aquaculture cage. Background Technology

[0002] Cage aquaculture is a production model that utilizes a box-shaped net structure to enclose a certain volume in natural waters (oceans, lakes, reservoirs, rivers, etc.) for intensive fish farming. Its basic principle is to take advantage of the superior natural conditions of large bodies of water, allowing for continuous water exchange through the mesh of the net, creating a suitable living water environment for fish growth while effectively preventing fish from escaping.

[0003] Currently, in the process of cage aquaculture operations:

[0004] Traditional net cages have a fixed structure, making it difficult to adjust the cage depth. This results in poor adaptability to the aquaculture environment. Furthermore, most net cages are not equipped with nighttime warning functions, making them susceptible to collisions with boats at night or in low visibility conditions, causing equipment damage or aquaculture losses.

[0005] Therefore, in view of this, we have studied and improved the existing structure to provide a multifunctional aquaculture cage, in order to achieve a more practical value. Utility Model Content

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A multifunctional aquaculture cage includes a steel structure cage with a double door hinged at the top.

[0011] A set of diagonally opposite sides of the steel structure cage is fixedly installed with a traction steel rope. A waterproof box is set at the end of the traction steel rope away from the steel structure cage. A stepper motor is fixedly installed inside the waterproof box. The output shaft of the stepper motor is connected to a winding wheel through a coupling. One end of the traction steel rope is wound around the side of the winding wheel.

[0012] A float is fixedly installed at the top of the waterproof tank, a fluorescent lamp is fixedly installed at the top of the float, a vent valve is fixedly installed at the bottom of the float, an electric telescopic rod is fixedly installed inside the float, and a piston plate is fixedly installed at the output end of the electric telescopic rod, the piston plate sliding inside the float.

[0013] Furthermore, the side length of the square mesh of the steel structure cage ranges from 1.5 to 2.5 cm.

[0014] Furthermore, the free side of the double doors is fixed by bolts after they are closed.

[0015] Furthermore, the waterproof box is a sealed box with a copper structure, and the exterior of the waterproof box is coated with anti-corrosion paint.

[0016] Furthermore, batteries are concealed and fixed inside the top of the float and inside the waterproof tank.

[0017] Furthermore, both the stepper motor and the electric telescopic rod are equipped with wireless signal units.

[0018] Furthermore, the vent valve is a waterproof valve, allowing gas to flow only from the inside and outside of the float.

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] ① This solution uses a stepper motor to drive a winding wheel to release and retract the traction steel rope, which allows for remote control of the suspension depth of the steel structure cage in the water. Users can flexibly adjust the water layer where the cage is located according to the season, water temperature, light, or the needs of the fish growth stage, thereby providing a more suitable growth environment for the cultured organisms and improving the survival rate and product quality.

[0022] ②This solution uses fluorescent lights installed on the top of the floats to automatically illuminate at night or in low visibility weather conditions, effectively warning passing vessels, significantly reducing the risk of the net cages being damaged by collisions, and ensuring the safety of aquaculture facilities and the continuity of the aquaculture process;

[0023] ③ In this design, the piston plate is driven by an electric telescopic rod to move within the float, changing the air volume inside the float and thus actively adjusting the buoyancy of the entire device. This not only allows the cage to adapt to natural fluctuations in water level but also enhances system stability and reduces the risk of capsizing by increasing the draft during windy and wavy weather.

[0033] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] Please see Figure 1 - Figure 4 A multifunctional aquaculture cage includes a steel structure cage 1, with a double door 101 hinged to the top of the steel structure cage 1.

[0036] A set of diagonally opposite sides of the steel structure cage 1 are fixedly installed with traction steel ropes 2. A waterproof box 3 is set at the end of the traction steel ropes 2 away from the steel structure cage 1. A stepper motor 301 is fixedly installed inside the waterproof box 3. The output shaft of the stepper motor 301 is connected to a winding wheel 302 through a coupling. One end of the traction steel rope 2 is wound around the side of the winding wheel 302.

[0037] A float 4 is fixedly installed at the top of the waterproof tank 3. A fluorescent lamp 401 is fixedly installed at the top of the float 4. A vent valve 402 is fixedly installed at the bottom of the float 4. An electric telescopic rod 403 is fixedly installed inside the float 4. A piston plate 404 is fixedly installed at the output end of the electric telescopic rod 403. The piston plate 404 slides inside the float 4.

[0038] See Figure 1 , Figure 2 Specifically, the side length of the square mesh of the steel structure cage 1 ranges from 1.5 to 2.5 cm.

[0039] Controlling the side length range of the square mesh of the steel structure cage 1 can prevent farmed fish from escaping from the inside of the steel structure cage 1, and can also prevent predators of the farmed fish from entering the steel structure cage 1.

[0040] Specifically, the free side of the double door 101 is fixed by bolts after it is closed.

[0041] This creates a sealed structure to handle fish, and opening the double doors 101 makes it easy to capture the farmed fish in the steel structure net cage 1.

[0042] See Figure 1 , Figure 3 Specifically, the waterproof box 3 is a sealed box with a copper structure, and the exterior of the waterproof box 3 is coated with anti-corrosion paint.

[0043] The good thermal conductivity of the copper structure facilitates the outward conduction of heat from the stepper motor 301 during operation, which is then dissipated by the water flow.

[0044] See Figure 1 , Figure 4 Specifically, the inner top of the float 4 and the interior of the waterproof box 3 both conceal and fix the storage battery 405.

[0045] The stepper motor 301 and the electric telescopic rod 403 are powered by a storage battery 405, and the storage battery 405 can be easily charged.

[0046] See Figure 1 , Figure 3 , Figure 4 Specifically, both the stepper motor 301 and the electric telescopic rod 403 are equipped with wireless signal units.

[0047] The stepper motor 301 and the electric telescopic rod 403 can be easily controlled remotely via a wireless signal unit.

[0048] Specifically, the vent valve 402 is a waterproof valve that only allows gas to flow from inside and outside the float 4.

[0049] A waterproof valve is installed so that when the float 4 is above the water surface, it can automatically replenish gas when the electric telescopic rod 403 retracts, maintaining the buoyancy of the float 4 and preventing water backflow.

[0050] Working principle:

[0051] When deploying the cage system, the main buoyancy is initially provided by the float 4 at the top of the waterproof tank 3, suspending the entire device in the water. Initially, the electric telescopic rod 403 can be remotely controlled to move the piston plate 404 within the float 4. When the piston plate 404 retracts, the internal volume of the float 4 increases, the internal air pressure decreases, and external air is drawn in through the waterproof vent valve 402 at the bottom, thereby increasing buoyancy and causing the steel cage 1 to float. Conversely, when the piston plate 404 extends, compressed air is discharged from the vent valve 402, buoyancy decreases, and the steel cage 1 sinks. This mechanism allows for fine-tuning of the overall buoyancy of the steel cage 1.

[0052] The depth of the steel structure cage 1 is primarily adjusted by winding and unwinding the traction steel rope 2. The user sends a command via wireless signal, activating the stepper motor 301 inside the waterproof tank 3, which drives the winding wheel 302 to rotate, thereby tightening or releasing the traction steel rope 2. Since the traction steel rope 2 is fixed to the diagonal side of the steel structure cage 1, its winding and unwinding directly changes the position of the steel structure cage 1 relative to the waterproof tank 3 and the float 4, thus achieving precise and stable control of the depth of the steel structure cage 1 in the water.

[0053] At night, the fluorescent light 401 at the top of the float 4 is powered by the battery 405 to serve as a warning. The entire system is powered by the concealed battery 405 and receives control signals through a wireless signal unit, enabling remote and intelligent operation of all functions.

[0054] In summary, this device, through the combination of mechatronics and buoyancy control technology, intelligently solves the problems of traditional net cages, such as fixed depth, lack of warning functions, and poor resistance to environmental changes, providing a safe, efficient, and intelligent new type of aquaculture equipment.

[0055] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
