Description

Technical Field

[0001] This utility model relates to the field of abalone farming technology, and in particular to an escape-proof abalone farming cage. Background Technology

[0002] Abalone, a high-value-added seafood delicacy, has seen its aquaculture industry become an important part of my country's marine aquaculture sector. With the continuous growth of consumer market demand, abalone farming methods are gradually shifting from traditional intertidal reef and pond farming to intensive and large-scale methods such as deep-sea cage farming and floating cage farming. Among these, cage farming has become one of the mainstream methods for large-scale abalone farming due to its advantages such as relatively low cost, convenient management, ability to simulate natural marine environments, and ease of controlling farming conditions. It is widely used in nearshore shallow seas, harbors, and semi-enclosed sea areas.

[0003] However, most abalone farming cages have the following disadvantages:

[0004] (1) Manually opening and closing the cover takes a certain amount of time. During high-frequency operations such as feeding and inspection, if the staff forgets to close the cover in time after it is opened, or if it is not completely closed when it is closed, the abalone (especially the small and active juvenile abalone) will escape quickly through the opening, causing aquaculture losses.

[0005] (2) Net cages are difficult to clean. If net cages are not cleaned for a long time, a series of chain problems will be triggered, which will seriously affect the aquaculture benefits. First, the water quality will deteriorate severely. After the mesh of the net is blocked, the water exchange efficiency will drop significantly. The abalone's excrement and uneaten feed cannot be discharged in time and will accumulate and ferment in the net cage. This will lead to an increase in the concentration of harmful substances such as ammonia nitrogen and nitrite, and a decrease in dissolved oxygen content. The abalone will experience problems such as hypoxia and loss of appetite, and their growth rate will slow down significantly. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The technical problem solved by this utility model is to provide a highly practical abalone farming cage that is simple to operate and has a relatively simple structure, thus solving the problems of abalone easily escaping and the cage being difficult to clean mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: an escape-proof abalone farming cage, comprising an outer frame, a top plate fixedly connected to one side of the top of the outer frame, and suspension columns fixedly connected to both sides of the bottom wall of the top plate. A spring is sleeved on the surface of the suspension column, and a top cover is fixedly connected to one end of the spring. A bracket is slidably connected to the top edge of the outer frame, and a brush plate is fixedly connected to one side of the bracket. A cleaning brush block is fixedly connected to the surface of the bracket.

[0010] Optionally, a ball bearing is provided on the surface of one end of the bracket, a throttle is fixedly connected to the top of the bracket, a bearing is fixedly connected to the surface of the other end of the bracket, and a disc is fixedly connected to the surface of the bearing.

[0011] Optionally, four support rods are evenly fixedly connected to one side of the outer frame, and wire mesh is provided inside both the outer frame and the support rods.

[0012] Optionally, a circular hole is provided in the center of the surface of the top plate, the diameter of the top cover is larger than the diameter of the circular hole, and pull rings are provided on both sides of the upper surface of the top plate.

[0013] Optionally, a chassis is fixedly connected to one side of the bottom of the outer frame, and the bottom of the chassis is fixedly connected to the top of the disc.

[0014] Optionally, a cross is fixedly connected to the upper surface of the chassis, and the surface of the cross is uniformly provided with round holes.

[0015] (III) Beneficial Effects

[0016] This utility model provides an escape-proof abalone farming cage, which has the following beneficial effects:

[0017] 1. This escape-proof abalone farming cage features a unique design. When feeding, checking abalone growth, or performing other operations, workers can press down on the top cover. This compresses the spring along the suspension column, opening the round hole on the top plate. After the operation is complete, the worker releases the top cover, and the compressed spring automatically rebounds, resetting the top cover and completely covering the round hole again. This process minimizes the time the top of the cage is open and prevents farmers from forgetting to close the feeding inlet, thus preventing abalone escape.

[0018] 2. This escape-proof abalone farming cage, through the setting of brush plates and cleaning blocks, firstly ensures efficient water circulation, allowing fresh seawater to smoothly enter the cage and remove pollutants such as feces and uneaten feed produced by abalone metabolism, providing sufficient dissolved oxygen for abalone; secondly, it maintains a stable farming environment, reduces water quality deterioration caused by the decay of attached materials, and lowers the risk of abalone disease; thirdly, it extends the service life of the cage, avoids corrosion of wire mesh, support rods and other components by attached materials, and reduces equipment replacement costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: an escape-proof abalone farming cage, including an outer frame 1, a top plate 2 fixedly connected to one side of the top of the outer frame 1, and suspension columns 3 fixedly connected to both sides of the bottom wall of the top plate 2. A spring 4 is sleeved on the surface of the suspension column 3, and a top cover 5 is fixedly connected to one end of the spring 4. A bracket 6 is slidably connected to the top edge of the outer frame 1, a brush plate 7 is fixedly connected to one side of the bracket 6, and a cleaning brush block 8 is fixedly connected to the surface of the bracket 6.

[0026] The surface of one end of the bracket 6 is provided with ball bearings 9 to reduce the sliding friction between the bracket 6 and the top edge of the outer frame 1, making the bracket 6 move more smoothly and reducing the resistance of the cleaning operation. The top of the bracket 6 is fixedly connected to a handle 10, which provides a point of leverage for the operator. The surface of the other end of the bracket 6 is fixedly connected to a bearing 11, and the surface of the bearing 11 is fixedly connected to a disc 12.

[0027] Four support rods 13 are evenly fixed to one side of the outer frame 1. They are evenly fixed to the side of the outer frame 1 to help the outer frame 1 enhance the structural strength of the net cage and prevent the net cage from deforming due to water flow impact. The outer frame 1 and the support rods 13 are both equipped with wire mesh 14. The wire mesh 14 is the growth carrier of abalone and also plays a protective role, preventing abalone from escaping from the side of the net cage and enabling water exchange.

[0028] A circular hole is provided in the center of the surface of the top plate 2. The diameter of the top cover 5 is larger than the diameter of the circular hole. Pull rings 15 are provided on both sides of the upper surface of the top plate 2. The pull rings 15 are mainly used to connect ropes, anchors and other fasteners.

[0029] A chassis 16 is fixedly connected to one side of the bottom of the outer frame 1, and the bottom of the chassis 16 is fixedly connected to the top of the disc 12.

[0030] A cross 17 is fixedly connected to the upper surface of the base 16. The surface of the cross 17 is evenly provided with round holes and is fixed to the upper surface of the base 16. The round holes on the surface can enhance the water flow at the bottom, while dispersing the weight of abalone and attached organisms, and also ensuring the stability of the bottom structure of the cage.

[0031] In this invention, the working steps of the device are as follows:

[0032] Step 1: Place the outer frame 1 into the aquaculture area. Secure the net cage to the designated water area using the pull ring 15 on the nail plate 2 in conjunction with ropes or anchors, ensuring the outer frame 1 remains stable and preventing it from tipping over due to water flow. Simultaneously check the connection between the base plate 16 and the disc 12 for secureness, and the stability of the cross 17 to provide stable bottom support for abalone growth. Press down on the top cover 5 to compress the spring 4, opening the round hole on the nail plate 2. Place the abalone seedlings into the net cage through the round hole. After placement, release the top cover 5; the spring 4 will automatically return, resetting the top cover 5 and closing the round hole to prevent abalone escape.

[0033] Step 2: Each time you feed the abalone or check its growth, repeat the steps of "pressing the top cover 5 - opening the round hole - completing the operation - releasing and resetting". With the help of the automatic rebound function of the spring 4, the opening time can be reduced. During the inspection, you can observe whether the wire mesh 14 is damaged.

[0034] Third step: When obvious deposits are found on the surface of the wire mesh 14, turn the handle 10 at the top of the bracket 6. With the sliding action of the ball bearing 9 and the rotation of the bearing 11, the bracket 6 is moved along the top edge of the outer frame 1, so that the brush plate 7 is in contact with the surface of the wire mesh 14 to brush away the deposits, and the cleaning block 8 scrapes away stubborn stains to achieve a thorough cleaning. After cleaning, turn the bracket 6 back to the initial position.
