Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture bottom-sitting technology, specifically to a bottom-sitting automatic feeding device for deep-sea sea cucumber aquaculture. Background Technology

[0002] A deep-sea aquaculture cage is a tool used for deep-sea aquaculture. It mainly consists of a frame system, net cage, fixing system and supporting facilities. It utilizes the interaction of the fixed platform and the characteristics of the cage itself to lower the cage to a limited depth underwater.

[0003] Existing sea cucumber farming techniques typically involve placing sea cucumbers in enclosed farming cages and releasing them into the deep sea. Feeding is then done periodically, usually by retrieval of the farming cages, opening them to feed the sea cucumbers, closing them again, and releasing them back into the deep sea. Because the retrieval process needs to be done slowly, as rushing could break the ropes, it is quite time-consuming. Therefore, a bottom-mounted automatic feeding device for deep-sea sea cucumber farming has been disclosed. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a bottom-mounted automatic feeding device for deep-sea sea cucumber farming.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] An automatic bottom-feeding device for deep-sea sea cucumber farming includes a feeding component, a feeding pipe, and a water pumping component. One end of the feeding pipe is connected to the top of one side of an existing aquaculture cage. The feeding component feeds the fish into the feeding pipe, and the water pumping component pumps water from the bottom of the existing aquaculture cage.

[0007] As a further embodiment of this utility model: the feeding assembly includes a feed conveyor, which is a screw conveyor. The base of the feed conveyor is fixed on the platform of the existing floating platform, and the discharge port of the feed conveyor is set downward.

[0008] As a further embodiment of this utility model: the feeding assembly also includes an intermediate pipe, an intermediate hopper, and an impeller pump. The mounting base of the impeller pump is fixedly installed on the platform of the existing floating platform. The two ends of the intermediate pipe are respectively connected to the hopper opening of the intermediate hopper and the discharge port of the feed conveyor. The intermediate hopper is completely submerged in the sea and the hopper opening is close to the existing floating platform. A connecting pipe is fixed to the outside of the intermediate hopper and connected to it. A connecting hose is fixed between the pumping end of the impeller pump and the discharge port of the intermediate hopper to connect the two. The outlet end of the impeller pump is connected to the other end of the feeding pipe.

[0009] As a further improvement of this utility model: a perforated plate is fixed at one end of the connecting pipe located on the outside of the middle hopper.

[0010] As a further embodiment of this utility model: the water pumping assembly includes a water pump and a water pumping hose. The mounting base of the water pump is fixedly installed on the platform of the existing floating platform. One end of the water pumping hose is connected to the bottom side of the existing aquaculture cage, and the other end of the water pumping hose is connected to the water pumping end.

[0011] As a further improvement of this utility model, the feeding pipe, the water pumping hose, and the connecting hose are all made of neoprene rubber.

[0012] As a further improvement of this utility model: the inner wall of the feeding tube is fixed with a plurality of rings coaxially arranged therewith, and the inner ring of the rings is inclined downward.

[0013] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0014] Firstly, this utility model is equipped with a feeding pipe that is connected to the top of the net cage. Feed is put into the feeding pipe and water is supplied to the feeding pipe. The feed is carried into the inside of the aquaculture net cage by the water flow, thus eliminating the need to scoop up the feed for feeding.

[0015] Secondly, the feed pipe has an inner ring that slopes downwards. This ring acts as an obstruction, preventing feed from being unable to enter the aquaculture cage smoothly due to the backflow of some water (the backflowing feed comes into contact with the ring, reducing the feed speed and causing the feed to sink; the ring acts like a settling plate in existing technology).

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 In this embodiment of the utility model, a bottom-mounted automatic feeding device for deep-sea sea cucumber farming includes a feeding component, a feeding pipe 4, and a water pumping component. One end of the feeding pipe 4 is connected to the top of one side of an existing aquaculture cage. The feeding component feeds the feed into the feeding pipe 4, and the water pumping component pumps water from the bottom of the existing aquaculture cage.

[0023] Specifically, in conjunction with the appendix Figure 1 As shown, the feeding assembly includes a feed conveyor 1, which is a screw conveyor. The base of the feed conveyor 1 is fixed on the platform of the existing floating platform. The discharge port of the feed conveyor 1 is set downwards. The screw conveyor is existing technology, and its specific structure and working principle will not be described in detail here. The screw conveyor is used to transport granular feed.

[0024] Specifically, in conjunction with the appendix Figure 1 - Appendix Figure 3 As shown, the feeding assembly also includes an intermediate pipe 6, an intermediate hopper 5, and an impeller pump 2. The mounting base of the impeller pump 2 is fixedly installed on the platform of the existing floating platform. The two ends of the intermediate pipe 6 are respectively connected to the hopper opening of the intermediate hopper 5 and the discharge port of the feed conveyor 1. The intermediate hopper 5 is completely submerged in the sea, and the hopper opening of the intermediate hopper 5 is close to the existing floating platform. A connecting pipe 7 is fixed to the outside of the intermediate hopper 5 and is connected to it. A connecting hose 9 is fixed between the water pump end of the impeller pump 2 and the discharge port of the intermediate hopper 5 to connect the two. The outlet of pump 2 is connected to the other end of the feeding pipe 4; the impeller pump 2 is existing technology and its specific structure and working principle will not be described in detail here. The impeller pump 2 can transport seawater containing particulate matter; the feed conveyor 1 sends the feed into the intermediate pipe 6, and the feed falls into the intermediate hopper 5 through the intermediate pipe 6. The impeller pump 2 starts and pumps water into the intermediate hopper 5. The impeller pump 2 sends the seawater containing particulate matter into the feeding pipe 4. The feed in the feeding pipe 4 flows into the aquaculture cage with the help of the flowing water.

[0025] Specifically, in conjunction with the appendix Figure 3 As shown, a mesh plate 10 is fixed at one end of the connecting pipe 7 located outside the middle hopper 5. The mesh plate 10 is designed to prevent feed from flowing out of the connecting pipe 7.

[0026] Specifically, in conjunction with the appendix Figure 2As shown, the water pumping assembly includes a water pump 3 and a water pump hose 8. The mounting base of the water pump 3 is fixedly installed on the platform of the existing floating platform. One end of the water pump hose 8 is connected to the bottom side of the existing aquaculture cage, and the other end of the water pump hose 8 is connected to the water pump end of the water pump 3. Further explanation of the water pump 3 is provided here. The water pump 3 uses a low-power design to prevent the sea cucumbers inside the aquaculture cage from being sucked away during pumping. The water pump 3 pumps water from the bottom of the cage through the water pump hose 8, accelerating the flow of seawater inside the aquaculture cage and carrying away some sea cucumber metabolites. The flowing seawater can disperse the sea cucumber metabolites, which then flow out of the aquaculture cage.

[0027] Specifically, in conjunction with the appendix Figure 1 As shown, the feed pipe 4, the pumping hose 8, and the connecting hose 9 are all made of neoprene rubber. Neoprene rubber is one of the commonly used materials for deep-sea hoses. Neoprene rubber has advantages such as high wear resistance and corrosion resistance.

[0028] Specifically, in conjunction with the appendix Figure 4 As shown, the inner wall of the feeding pipe 4 is fixed with a plurality of rings 11 arranged coaxially therewith, and the inner ring of the rings 11 is inclined downward.

[0029] The feed pipe 4 is equipped with a downward-sloping inner ring 11. This ring 11 can act as an obstruction to prevent feed from being unable to enter the aquaculture cage smoothly due to the backflow of some water (the backflowing feed comes into contact with the ring 11, which reduces the feed speed and causes the feed to sink, so the ring 11 acts as a settling plate as in the prior art).

[0030] To supplement the above: The entire device is equipped with an external controller, and all the aforementioned electrical components are electrically connected to the controller. The controller can have a built-in timer, and it can control the periodic opening and closing of each electrical component.

[0031] Working principle:

[0032] The first step is to start the water pump 3. The water pump 3 pumps water to the bottom of the net cage through the water pumping hose 8, which accelerates the flow of seawater inside the aquaculture net cage and carries away some of the sea cucumber metabolites. The flowing seawater can disperse the sea cucumber metabolites and the dispersed sea cucumber metabolites flow out of the aquaculture net cage.

[0033] The second step is to stop the water pump 3 after it has been working for a period of time. Then the controller shuts down the water pump 3, and the feed conveyor and impeller pump 2 start at the same time. The feed conveyor 1 sends the feed into the intermediate pipe 6. The feed falls into the intermediate hopper 5 through the intermediate pipe 6. The impeller pump 2 starts and pumps water into the intermediate hopper 5. The impeller pump 2 sends seawater containing particles into the feeding pipe 4. The feed in the feeding pipe 4 flows into the aquaculture cage with the help of the flowing water.

[0034] Third, after the feed conveyor and impeller pump 2 have been working for a period of time, the controller first shuts down the feed conveyor, allowing the impeller pump 2 to continue working for a period of time (to ensure that the feed can be completely delivered into the aquaculture cage), and then shuts down the impeller pump 2.

[0035] Fourth step: Set the start time, and repeat steps one through three until the next feeding time.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
