[0002] Feeding is a crucial aspect of aquaculture production. The methods of feeding vary depending on the farming model, the type of aquatic product, and the climate and season.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 12 As shown, the pneumatic and hydraulic automatic feeding system of the present invention includes a control module, a storage module, a pneumatic conveying module, and a hydraulic conveying module;

[0040] The control module is a control cabinet module used to control the operating status of the storage module, pneumatic conveying module and hydraulic conveying module.

[0041] The storage module is used to store feed; the storage module includes a hopper 1 and a set of rotary feeders 2; the hopper 1 is provided with a feeding port 3;

[0042] The silo 1 is preferably equipped with a vent valve, a temperature and humidity sensor, a level gauge, and a weight gauge;

[0043] The pneumatic conveying module is used for pneumatic conveying and feeding of feed; the pneumatic conveying module includes a blower 4, a feed distributor 5, and a set of surface feeders 6; the blower 4 is preferably a Roots blower 4; the feed distributor 5 is connected to a pneumatic conveying pipe 7; the pneumatic conveying pipe 7 is connected to a rotary feeder 2 through a pipeline; the pneumatic conveying pipe 7 is connected to the blower 4 through a pipeline; the feed distributor 5 and the surface feeders 6 are connected by a pneumatic feeding pipe 8; each surface feeder 6 corresponds to one feeding port;

[0044] The hydraulic conveying module is used for hydraulic conveying and feeding of feed; the hydraulic conveying module includes a set of hydraulic conveying units; the hydraulic conveying unit includes a mixing tank 9, a seawater pump 10, a jet pump 11, and a set of underwater feeders 12; the mixing tank 9 is connected to the rotary feeder 2 via a pipeline; the mixing tank 9 is connected to the jet pump 11 via a pipeline; the seawater pump 10 and the jet pump 11 are connected via a hydraulic conveying pipe 13; the jet pump 11 and the underwater feeders 12 are connected via a hydraulic feeding pipe 14; each underwater feeder 12 corresponds to one feeding port;

[0045] The mixing tank 9 is preferably equipped with a level gauge and a vent pipe; the pneumatic conveying pipe 7, the pneumatic feeding pipe 8, the hydraulic conveying pipe 13 and the hydraulic feeding pipe 14 are preferably equipped with pressure sensors and flow meters;

[0046] An electric slide gate valve is installed between the hopper 1 and the rotary feeder 2; an electric remote control valve is installed on the pneumatic conveying pipe 7, the pneumatic feeding pipe 8, the hydraulic conveying pipe 13 and the hydraulic feeding pipe 14.

[0047] The pipeline is equipped with necessary monitoring instruments and accessories. Through a control module, it can automatically feed fish at set times and in measured quantities. The feeding rate can be adjusted according to feeding needs, and the opening and closing of some feeding ports can be automatically controlled based on water flow direction and velocity to prevent feed from flowing out of the rearing cages and being wasted when the flow rate is high. The feeding system has a communication data exchange interface with a system for recognizing uneaten feed and fish feeding characteristics, and can automatically adjust the feeding rate based on feedback.

[0048] The inner wall and joints of the feeding pipe should be smooth and corrosion-resistant. Stainless steel or PE pipes should be used. The bending radius of the pipe should not be less than 6D and there should be as few welded joints as possible. If welded joints are unavoidable, the back excess height should not exceed 2mm and there should be no obvious barbs or protrusions to ensure the smooth inner wall.

[0049] For details of the connection structure and working process of this invention, please refer to [link / reference]. Figures 1 to 4Primarily used in multi-condition aquaculture, this system can meet the feeding needs of semi-submersible and fully submersible bottom-feeding aquaculture. In semi-submersible conditions, pneumatic feeding is used, while in bottom-feeding conditions, underwater hydraulic feeding is employed. The feeding mode can be switched according to different aquaculture conditions, reducing the workload of feeding personnel. The pneumatic feeding system is equipped with a pre-activated Roots blower 4 to purge the feeding pipeline and a delayed shutdown to prevent residual feed from accumulating in the pipeline. The hydraulic feeding system is equipped with a pre-activated seawater pump 10 to flush the feeding pipeline and a delayed shutdown to flush the pipeline, preventing residual feed and marine organisms from accumulating in the pipeline.

[0050] In a preferred embodiment of the present invention, both the pneumatic feeding pipe 8 and the hydraulic feeding pipe 14 are provided with inspection ports 15; an installation box 16 is fixedly connected to the surface of the hydraulic feeding pipe 14; an inspection window 17 is opened on the surface of the hydraulic feeding pipe 14 inside the installation box 16; an electric telescopic rod 18 is fixedly connected inside the installation box 16; the extension of the electric telescopic rod 18 faces the inspection window 17 and is fixedly connected to a lifting block 19; cameras 20 are fixedly connected to both ends of the lifting block 19; a light is provided at the bottom of the camera 20; and an opening and closing assembly is provided inside the inspection window 17.

[0051] The opening and closing assembly includes a slide groove; the slide groove is opened inside the side wall of the hydraulic feeding pipe 14 at the position corresponding to the inspection window 17; a pair of arc-shaped plates 21 are slidably connected inside the slide groove; a set of springs 22 are fixedly connected between the arc-shaped plates 21 and the slide groove; a steel wire rope 23 is fixedly connected to the end of the arc-shaped plates 21 away from the inspection window 17; the steel wire rope 23 extends into the mounting box 16 and passes around a set of guide wheels before being fixedly connected to the top of the lifting block 19;

[0052] The inspection port 15 is used for inspecting the feeding pipe. When the pneumatic feeding pipe 8 located on the water surface experiences blockages, damage, or other malfunctions, its inspection port 15 can be opened directly to observe its internal condition, determine the cause of the malfunction, and carry out corresponding repairs. However, the hydraulic feeding pipe 14 located underwater is usually located in deep seawater, making it difficult to inspect. When it malfunctions, personnel typically need to wear professional diving equipment to descend into the deep seawater to inspect it and determine the cause of the malfunction, which is a cumbersome process and poses safety risks. In this invention, when it is necessary to inspect the underwater hydraulic feeding pipe 14, it is only necessary to remotely control the electric telescopic rod 18 to extend downwards, driving the lifting block 19 downwards. The movement causes the lifting block 19 to pull a pair of arc-shaped plates 21 to both sides via the steel wire rope 23, causing the arc-shaped plates 21 to retract into the chute and open the inspection window 17. Then, the lifting block 19 enters the hydraulic feeding pipe 14 through the inspection window 17, allowing the internal condition of the hydraulic feeding pipe 14 to be observed through a pair of cameras 20. This enables remote inspection of the hydraulic feeding pipe 14, facilitating the identification of fault causes and improving the maintenance efficiency of the feeding pipeline. Afterward, the electric telescopic rod 18 is controlled to retract and drive the lifting block 19 back to the installation box 16. The spring 22 pushes the pair of arc-shaped plates 21 together and closes the inspection window 17, preventing a large amount of feed from the hydraulic feeding pipe 14 from flowing into the installation box 16.

[0053] Once the camera 20 identifies the cause of the malfunction in the hydraulic feeding pipe 14, if the problem is minor, such as a blockage, the staff may choose not to go into the water. They can simply use the seawater pump 10 to pressurize the water flow and clear the blockage. Only when a more serious malfunction occurs will the staff need to go into the water to repair the hydraulic feeding pipe 14 through the inspection port 15, thereby reducing the frequency of staff going into the water and minimizing safety risks.

[0054] In a preferred embodiment of the present invention, an inverted "U"-shaped bracket 24 is fixedly connected to the fixed rod surface of the electric telescopic rod 18; a protective pad 25 is fixedly connected to both bottom sides of the bracket 24 near the camera 20, and the protective pad 25 is in close contact with the camera 20; the protective pad 25 is made of an elastic porous material, such as sponge or foam; after the camera 20 enters the hydraulic feeding pipe 14, it is easy to come into contact with residual feed and other debris in the pipe. Therefore, when the lifting block 19 returns to its original position between the brackets 24, the electric telescopic rod 18 is controlled to contract and extend slightly, so that the protective pad 25 wipes the lens surface of the camera 20, thereby removing the feed and other debris adhering to the surface of the camera 20, improving the observation effect of the camera 20. The porous protective pad 25 allows the removed feed and other impurities to enter the interior of the protective pad 25, preventing the impurities from constantly rubbing between the protective pad 25 and the camera 20, which would cause the lens to be scratched. Afterwards, since the protective pad 25 covers the surface of the camera 20, it can also prevent aquatic organisms from parasitizing the lens surface.

[0055] A sewage pump 26 is fixedly connected to the bottom of one side of the installation box 16, and the sewage pump 26 is connected to the inside of the installation box 16; a water inlet 27 is opened on the other side of the installation box 16; a filter screen 28 is fixedly connected inside the water inlet 27; since feed inside the hydraulic feeding pipe 14 can easily enter the installation box 16 when the inspection window 17 is open (especially when the hydraulic feeding pipe 14 is blocked), causing pollution to the water quality inside the installation box 16, after the lifting block 19 is reset to the inside of the installation box 16, the water mixed with feed inside the installation box 16 is first discharged out through the sewage pump 26, and the seawater from the outside enters the installation box 16 through the water inlet 27 to balance the pressure, thereby purifying the internal environment of the installation box 16. Then, the camera 20 is cleaned using the protective pad 25, which can improve its cleaning effect and prevent feed and other impurities from contaminating the camera 20 again after cleaning.

[0056] In a preferred embodiment of the present invention, a mesh cover 29 is fixedly connected to the inner wall of the mounting box 16 at the position corresponding to the inlet 27; a spherical block 30 is provided inside the mesh cover 29; an elastic pressure block 31 is fixedly connected between the spherical block 30 and the mesh cover 29; when the sewage pump 26 is turned on, a negative pressure is generated inside the mounting box 16, thereby separating the spherical block 30 from the inlet 27 and compressing the elastic pressure block 31, at which time seawater from the outside can enter the mounting box 16 through the inlet 27; when the sewage pump 26 is turned off... After closing, the elastic block 31 presses the spherical block 30 back onto the surface of the inlet 27 and seals it, preventing the feed inside the hydraulic feeding pipe 14 from leaking out in large quantities through the installation box 16 and the inlet 27 when the inspection window 17 is opened, thus preventing waste. In addition, as the elastic block 31 pushes the spherical block 30 toward the inlet 27, the spherical block 30 pushes the seawater in front of it toward the filter screen 28, backwashing the filter screen 28 and removing the debris adhering to the outside of the filter screen 28, thereby improving the water passage efficiency of the filter screen 28.

[0057] A flexible ring 32 is fixedly connected to the inlet 27 at the corresponding position of the spherical block 30; a connecting hole 33 is opened inside the spherical block 30; a connecting rod 34 is fixedly connected to the side of the filter screen 28 near the spherical block 30, and the connecting rod 34 is slidably connected inside the connecting hole 33; by setting the flexible ring 32, the fitting effect between the spherical block 30 and the inlet 27 can be improved. During the movement of the spherical block 30, the connecting rod 34 slides inside the connecting hole 33, thereby limiting the movement direction of the spherical block 30, so that the spherical block 30 is always aligned with the inlet 27, ensuring its sealing efficiency.

[0058] The elastic pressure block 31 is designed as a hollow structure; the bracket 24 is fixedly connected to the nozzle 35 at the corresponding position of the pad 25, and the nozzle 35 faces the top of the pad 25; the nozzle 35 and the interior of the elastic pressure block 31 are connected by a conduit 36; when the spherical block 30 separates from the water inlet 27 and compresses the elastic pressure block 31, the water inside the elastic pressure block 31 is sprayed into the interior of the pad 25 through the conduit 36 ​​and the nozzle 35, flushing out the impurities remaining inside the pad 25 downwards, thereby ensuring the cleanliness of the pad 25 itself and further improving the cleaning efficiency of the pad 25 for the camera 20. When the elastic pressure block 31 is reset, water is reabsorbed through the nozzle 35 and the conduit 36.

[0059] In a preferred embodiment of the present invention, the arc-shaped plate 21 has a groove on the side facing the inside of the hydraulic feeding pipe 14; an elastic pad 37 is fixedly connected inside the groove; a set of elastic elements 38 are evenly distributed between the elastic pad 37 and the groove; the side of the elastic pad 37 near the spring 22 is chamfered; when a pair of arc-shaped plates 21 are closed together, under the action of the elastic elements 38, the lower side of the elastic pad 37 protrudes from the surface of the arc-shaped plate 21, thereby filling the recess of the arc-shaped plate 21, reducing the stepped structure between the arc-shaped plate 21 and the inside of the hydraulic feeding pipe 14, and thus reducing the resistance of the stepped structure to the feed when the hydraulic feeding pipe 14 is conveying feed. When the arc-shaped plate 21 is retracted into the chute, the side wall of the inspection window 17 squeezes the chamfer of the elastic pad 37, thereby facilitating the retraction of the elastic pad 37 into the groove.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
