Description

Technical Field

[0001] This utility model relates to a pond aquaculture feeding device, specifically a submersible pump-driven pond aquaculture flowing water feeding device, belonging to the field of aquaculture technology. Background Technology

[0002] Feeding is one of the core aspects of aquaculture that directly affects the profitability of the farming process. A proper feeding method can significantly improve feed utilization, promote the growth rate of farmed organisms, and reduce feed waste, uneaten feed pollution, and farming costs. Traditional feeding equipment, such as mechanical spreading devices or pneumatic conveying systems, while successfully achieving mechanized feeding, also brings the following problems:

[0003] First, the high-speed movement and collision of feed can easily lead to increased breakage; second, it is impossible to feed evenly, which can easily lead to local accumulation or sparse distribution of uneaten feed, affecting the water environment of the aquaculture pond and the feeding efficiency of aquaculture organisms; and third, it consumes a lot of energy.

[0004] Therefore, existing technologies also have related designs for underwater feeding. For example, Chinese patent document with publication date of April 28, 2023 and publication number CN116019044A discloses an aquaculture mixed feed feeding device and feeding method, which proposes the concept of underwater feeding. However, it still has shortcomings in terms of the fullness and uniformity of the mixing of feed and water, as well as the control of the distribution of feed. Utility Model Content

[0005] This invention proposes a submersible pump-driven water-feeding device. The device achieves initial mixing of feed and water through a feed-water mixing mechanism, followed by thorough and uniform mixing through a mixing bin in the mixing and feeding unit. A submersible pump in the mixing and feeding unit provides negative pressure, pumping the feed upwards to a combined feeding pipe above the water surface. Finally, positive pressure from distributed distribution pipes on the combined feeding pipe delivers the feed to the feeding point, forming an underwater distributed feeding system. This system effectively and evenly feeds the feed, achieving a large amount of water and a small amount of feed during the feeding process. It avoids pressure buildup and potential blockages caused by feed accumulation at bends during underwater feeding.

[0006] The present invention adopts the following technical solution:

[0007] A submersible pump-driven pond aquaculture feeding device includes a feed-water mixing and feeding machine 1, a mixing and feeding unit 2, and a combined feeding pipe 3. The feed-water mixing and feeding machine 1 is used to store feed and initially mix the feed with flowing water and then convey it. The mixing and feeding unit 2 is located below the water surface and includes, from bottom to top, a mixing bin 202, a submersible pump 201, and a float 203. The mixing bin 202 is connected to the conveying pipeline of the feed-water mixing and feeding machine 1 and has pores that communicate with the surrounding water. The submersible pump 201 is connected to the upper part of the mixing bin 202 and pumps the further mixed feed and flowing water in the mixing bin 202 upward to the combined feeding pipe 3 through negative pressure. The combined feeding pipe 3 includes a main conveying pipe 301, which extends horizontally above the water surface and has multiple branch conveying pipes 303 extending downward to below the water surface.

[0008] Preferably, the mixing hopper 202 has an outlet 202-2 at the center of its upper part that is connected to the submersible pump 201, and an inlet 202-1 is located on the side of the outlet 202-2 that is connected to the conveying pipeline of the material mixing and feeding mechanism 1.

[0009] Preferably, the inner bottom of the mixing bin 202 has a spherical structure.

[0010] Preferably, the mixing bin 202 has pores that communicate with the surrounding water body, specifically configured as having a grid-shaped water inlet trough on the side of the bin body, the width of the water inlet trough being smaller than the outer diameter of the smallest unit of feed.

[0011] Preferably, each of the conveying pipes 303 is provided with a feeding valve 302, which is also located above the water surface.

[0012] Furthermore, the main conveying pipe 301 is a rigid pipe, and the branch conveying pipe 303 is a flexible pipe used to convey feed to the feeding location; the feeding valve 302 is used to control the conveying sequence of the branch conveying pipe 303.

[0013] Furthermore, the main feed pipe 301, the branch feed pipe 303, and the feed valve 302 are modularly designed and can be added, removed, or extended according to the actual aquaculture conditions.

[0014] Preferably, the main feed pipe 301 is installed on one side wall or bank of the pond by means of a bracket or by direct fixing.

[0015] Furthermore, the discharge holes on the feed distribution pipe 303 are located on the same side of the feed distribution pipe 303; when the feed distribution pipe 303 discharges under positive pressure, the discharge direction is as downward as possible or inclined downward, the feed distribution pipe 303 is in a floating or suspended state, and its end points to the other side wall of the pond. The length of the feed distribution pipe 303 is selected according to the range of the pond to be covered.

[0016] Furthermore, the end of the feed distribution pipe 303 has an openable and closable structure for cleaning up residual feed.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1) Because the feed sinks slowly during the initial mixing, local blockages at pipe bends are likely to occur during underwater feeding due to low uniformity of feed-water mixing. This invention adopts a two-stage feed mixing process. In particular, the second stage, in the mixing and feeding unit 2, utilizes open water (mixing with external water through gaps) to enhance the uniformity of feed-water mixing. This achieves a large amount of water + a small amount of feed during feeding, improving feeding efficiency and utilization while avoiding pressure buildup or even blockages caused by feed accumulation at bends during underwater feeding.

[0019] 2) A single submersible pump is used as the power source to transport the water-material mixture to the feeding point through a pipeline. The power source is simple and reliable.

[0020] 3) Through the distributed pipeline layout and the floating or suspended state of the feed distribution pipes caused by the reaction force of water flow, it is possible to achieve full pond coverage for feed feeding. The pipeline can also be arranged according to the living habits of the farmed organisms, making feeding more precise.

[0021] 4) Feed can be delivered through pipes, which not only allows for precise and targeted feeding but also promotes the flow and circulation of aquaculture water.

[0022] 5) By cleverly utilizing the submersible pump to lift a small section upwards, the entire combined feed pipe is positioned above the water surface, facilitating maintenance and valve control;

[0023] 6) Modular conveying pipes are mainly composed of standardized components and pipes, which facilitates expansion or node selection as needed, and also makes maintenance easier. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] See Figure 1 A submersible pump-driven pond aquaculture feeding device includes: a feed-water mixing mechanism 1, four pillars installed at the four corners of the base plate of the feed-water mixing mechanism 1 as the main support, a plastic shell covering the outer shell of the box, an extension of the feed hopper installed with the pillars inside the box, a feed hole at the bottom, a short groove limiting door installed below the feed hole, a feed plate installed at an angle below the door, a funnel with an annular water outlet pipe at the larger end, a flexible feed pipe with one end inserted into the water outlet below the funnel, and a feed pump and controller installed inside the box and fixed to the base plate. The function required of the feed-water mixing mechanism 1 is the preliminary mixing of feed and water, which is not the focus of this utility model, and it is understood that it is achievable.

[0033] Figure 2 The external structure of the mixing and feeding unit 2 is shown. The inlet of the mixing bin 202 is inserted into one end of the feeding pipe of the material-water mixing mechanism 1 and secured with a clamp. The outlet is installed with screws and nuts to the water inlet of the submersible pump 201. The mixing bin 202 has a grid-like water inlet groove on its side. The top of the bin has an inlet and an outlet. The lower half of the mixing bin 202 is hemispherical. The mixing bin 202 is divided into upper and lower structures, which are installed by an interference fit with a pin. The upper part includes an inlet, an outlet, and a water inlet groove, while the lower part is a hemispherical bottom. The outlet of the submersible pump 201 is provided with a threaded nut. The outlet of the submersible pump 201 is inserted into the center of the float 203 and the nut is tightened for installation.

[0034] Figure 3The external structure of the combined feeding pipe 3 is shown. The submersible pump outlet is fastened to the main feeding pipe 301 by threads. The other end is extended by installing the main feeding pipe 301 according to actual needs. The two sections of the main feeding pipe 301 are connected by a water pipe connector. The end of the combined feeding pipe 3 is a funnel-shaped pipe connected to and equipped with a feeding valve 302 and a distribution feeding pipe 303. The distribution feeding pipe 303 has evenly distributed discharge holes on one side. The feeding valve 302 is a solenoid valve. All electrical wires along the main feeding pipe are waterproofed. When the entire device is working, the distribution feeding pipe 303 is suspended in the water or floats on the water surface. The feeding direction is as downward as possible. Since the distribution feeding pipe 303 is a flexible tube, it may also be in a constantly twisting state.

[0035] like Figure 2 and 5 As shown, the mixing and feeding unit 2 needs to be placed in water and floats by means of the float 203; the main conveying pipe 301 can be installed on the shore or erected on the water surface as shown in the figure; when installing the sub-conveying pipe 303, the discharge hole needs to be set in the direction towards the bottom of the water.

[0036] Working principle:

[0037] See Figure 5 As shown, the feed-water mixing mechanism is installed on the bank of the target water area. After the device is started, the feed-water mixing mechanism 1 draws water from the working water area and mixes the drawn water with the feed stored in the feed-water mixing mechanism 1. After the feed is initially mixed, it is transported to the mixing and feeding unit 2 through the feeding pipe. Under the action of gravity, the feed finally accumulates at the hemispherical bottom of the mixing bin 202. After a period of time, the submersible pump works and sends the feed in the mixing bin 202 to the combined feeding pipe 3 by the submersible pump 201. At this time, the feed and water are finally mixed. The feed passes through the main feeding pipe under the action of the submersible pump 201. The feeding valve 302 installed on the main feeding pipe 301 is opened as needed according to the control. The feed enters the branch feeding pipe 303 under the action of water flow and is finally discharged from the discharge hole on the branch feeding pipe 303, completing the feeding. The device stops feeding feed as a whole and continues to pump water to flush the pipe to clear the residual feed in the pipe.

[0038] This invention features a two-stage feed mixing system. Existing technologies use a single-stage mixing process, resulting in slow feed sinking. This leads to potential blockages at pipe bends during underwater feeding due to uneven mixing of feed and water. This invention employs a two-stage mixing system. In particular, the second stage, in the mixing and feeding unit 2, utilizes open water (mixing with external water through gaps) to enhance the uniformity of feed-water mixing. This achieves a large volume of water plus a small amount of feed during feeding, improving efficiency and utilization while preventing pressure buildup and blockages caused by feed accumulation at bends during underwater feeding. A single submersible pump is used as the feed mixing unit. The power source transports the water-feed mixture to the feeding point through pipelines, and the power source is simple and reliable. Through the distributed pipeline layout and the floating or suspended state of the distribution pipes caused by the reaction force of the water flow, it is possible to achieve full pond coverage for feeding. The pipeline can also be arranged according to the living habits of the farmed organisms, making feeding more precise. The feed is transported through pipeline water flow, which not only enables precise and targeted feeding, but also promotes the flow and circulation of the aquaculture water. The clever use of a submersible pump to lift the feed pipe slightly upwards allows the entire combined feeding pipe to be located above the water surface, which is convenient for maintenance and valve control. The combined feeding pipe is mainly composed of standardized components and pipes, which is conducive to expansion or node selection as needed, and is also easy to maintain.

[0039] The above are preferred embodiments of the present utility model. Those skilled in the art can make various changes or improvements based on this. Without departing from the overall concept of the present utility model, these changes or improvements should all fall within the scope of protection claimed by the present utility model.
