Technical Field
[0001] This utility model relates to the field of aquaponics technology, and in particular to a combined aquaponics separator net for aquaponics. Background Technology
[0002] Aquaponics is a new type of integrated farming system that combines two completely different agricultural techniques, aquaculture and hydroponics, through ingenious ecological design to achieve scientific synergy and symbiosis. This results in fish farming without water changes and water quality concerns, and vegetables growing normally without fertilizer.
[0003] A search revealed Chinese Patent CN213784899U, which discloses an aquaponics device for collecting rainwater. The device includes an aquaponics pool, a pump box fixedly installed on one side of the pool, a rainwater inlet pipe connected to one end of the pump box, a crossbar fixedly installed on the inner side of the pool, a cultivation board with cultivation holes placed on the inner side of the pool, and a fixing ring fixedly installed on the inner wall of the pool. The crossbar is designed to prevent the cultivation board from tipping over or sinking when plants grow on it, as the plants may alter the board's weight. A filter screen is installed at the bottom of the cultivation board to prevent fish fry from consuming the plant roots and stems, thus improving the device's practicality.
[0004] In the aforementioned existing technical solutions, a filter screen is installed at the bottom of the cultivation board. The filter screen can act as a separator to prevent fish fry from eating the roots and stems of the plants and affecting their growth. However, in actual use, fish excrement settles at the bottom of the symbiotic pond, while the filter screen blocks the roots and stems of the seedlings at the top, preventing the roots and stems from extending downwards to fully absorb the fish excrement. This results in the water quality not being effectively purified, which in turn affects the normal growth of both the fish fry and the seedlings. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model proposes a combined aquaponics separator net. A return pump pumps water and fish excrement from the aquaponics tank upwards through a return pipe and adjusting screw, feeding them into a collection plate. The collection plate collects the water and fish waste, which settles at the bottom due to gravity. A filter screen then filters the downward-flowing water, ensuring its cleanliness. Located at the bottom of the cultivation plate, the roots of the seedlings extend downwards through the cultivation holes, absorbing nutrients from the fish waste within the collection plate, thus promoting the growth of both the fish and seedlings.
[0006] The technical solution to achieve the purpose of this utility model is: a combined aquaponics separating net, including a symbiotic pool, a cultivation board is snapped into the inside of the symbiotic pool, a plurality of cultivation holes are opened on the top wall of the cultivation board, and a separating component is provided inside the symbiotic pool, the separating component including;
[0007] A collection plate is disposed inside the symbiotic pool. The collection plate is arc-shaped, and a filter screen is fixedly installed on the bottom wall of the collection plate.
[0008] An adjusting screw is rotatably mounted on the side wall of the cultivation plate, and the bottom thread of the adjusting screw passes through the collecting plate and the filter screen.
[0009] A reflux pump is fixedly installed on the bottom wall of the symbiotic tank. A reflux pipe is fixedly installed at the output end of the reflux pump, and the end of the reflux pipe away from the reflux pump is rotatably installed at the bottom of the adjusting screw.
[0010] There are multiple reflux holes, which are equidistantly spaced on the side wall of the adjusting screw.
[0011] In some embodiments, a sliding groove is provided on the inner bottom wall of the reflux hole, and a baffle plate is slidably installed inside the sliding groove.
[0012] In some embodiments, a fixing block is fixedly installed on the side wall of the baffle plate, and the fixing block is fixedly installed on the side wall of the collection plate.
[0013] In some embodiments, the filter screen is slidably mounted inside the symbiotic pool, with the sidewalls of the filter screen abutting against the inner sidewalls of the symbiotic pool.
[0014] In some embodiments, a rotating disk is fixedly mounted on the top wall of the adjusting screw.
[0015] In some embodiments, a guide plate is fixedly installed on the inner bottom wall of the symbiotic pool, the top wall of the guide plate is inclined, and the reflux pump is located at the lowest point of the guide plate.
[0016] Compared with the prior art, the significant advantages of this utility model are:
[0017] Firstly, this invention uses a reflux pump to pump water and fish excrement from the symbiotic pond upwards through a reflux pipe and adjusting screw, sending them into the collection plate. Because the collection plate is arc-shaped, it collects the water and fish waste. The fish waste settles at the bottom of the collection plate under gravity, while excess water overflows through it. The downward-flowing water is filtered through a filter screen to ensure cleanliness. Since the collection plate is located at the bottom of the cultivation plate, the roots of the seedlings inside the cultivation holes extend downwards to absorb nutrients from the fish waste inside the collection plate, which is beneficial to the growth of both the fish and seedlings. This solves the problem that the growth of both fish and seedlings is affected in existing symbiotic ponds.
[0018] Secondly, this utility model uses a baffle plate to block the space at the bottom of the return hole, so that the space on the return hole that is connected to the outside is aligned with the collecting plate, thus preventing the return pump from being unable to send water and fish waste into the collecting plate.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0026] This utility model provides an improved combined aquaponics separating net for aquaponics. The technical solution of this utility model is as follows:
[0027] like Figures 1-3As shown, a combined aquaponics separator net for aquaponics includes an aquaponics pool 1, a cultivation plate 2 snapped into the inside of the pool 1, and multiple cultivation holes 14 formed on the top wall of the cultivation plate 2. A separator assembly is installed inside the pool 1, including a collecting plate 3, an adjusting screw 7, a reflux pump 5, and reflux holes 8. The collecting plate 3 is located inside the pool 1 and is arc-shaped. A filter screen 4 is fixedly installed on the bottom wall of the collecting plate 3, and the filter screen 4 is slidably installed inside the pool 1, with its sidewalls fitting against the inner wall of the pool 1. The adjusting screw 7 is rotatably mounted on the sidewall of the cultivation plate 2, and its bottom thread passes through the collecting plate 3 and the filter screen 4. The reflux pump 5 is fixedly installed on the bottom wall of the pool 1, and a reflux pipe 6 is fixedly installed at its output end. The end of the return pipe 6 away from the return pump 5 is rotatably installed at the bottom of the adjusting screw 7; there are multiple return holes 8, which are equidistantly arranged on the side wall of the adjusting screw 7; the water and fish excrement inside the symbiotic tank 1 are transported upward through the return pipe 6 and the adjusting screw 7 by the return pump 5 and sent into the interior of the collecting plate 3. Since the collecting plate 3 is arc-shaped, it collects water and fish excrement. Under the influence of gravity, the fish excrement will settle at the bottom of the collecting plate 3, and the excess water will overflow through the collecting plate 3. The downward flowing water is filtered by the filter screen 4 to ensure the cleanliness of the water. The collecting plate 3 is located at the bottom of the cultivation plate 2. The roots of the seedlings inside the cultivation holes 14 will extend downward to absorb nutrients from the fish excrement inside the collecting plate 3, which is beneficial to the growth of the fish and seedlings.
[0028] like Figures 1-3 As shown, in this embodiment, a sliding groove 12 is provided on the inner bottom wall of the return hole 8. A baffle plate 9 is slidably installed inside the sliding groove 12. A fixing block 10 is fixedly installed on the side wall of the baffle plate 9, and the fixing block 10 is fixedly installed on the side wall of the collecting plate 3. The baffle plate 9 blocks the space at the bottom of the return hole 8, so that the space communicating with the outside of the return hole 8 is aligned with the collecting plate 3, thus preventing the return pump 5 from being unable to send water and fish waste into the collecting plate 3. A rotating disk 13 is fixedly installed on the top wall of the adjusting screw 7. The rotating disk 13 facilitates the rotation adjustment. The adjusting screw 7 is used, while the collecting plate 3 and the filter screen 4 are threaded onto the side wall of the adjusting screw 7, which allows the height of the collecting plate 3 and the filter screen 4 to be adjusted in real time according to the seedlings, so as to facilitate the growth of the seedlings; a guide plate 11 is fixedly installed on the inner bottom wall of the symbiotic pool 1. The top wall of the guide plate 11 is inclined, and the return pump 5 is located at the lowest point on the guide plate 11; the fish feces settled inside the symbiotic pool 1 are guided to the return pump 5 through the guide plate 11, so that the return pump 5 can transport the fish feces to the inside of the collecting plate 3, and at the same time further improve the cleanliness of the water source inside the symbiotic pool 1.
[0029] The specific working method is as follows: the water and fish excrement inside the symbiotic tank 1 are transported upward through the return pipe 6 and the regulating screw 7 by the return pump 5 and sent into the interior of the collecting plate 3. Since the collecting plate 3 is arc-shaped, it will collect water and fish excrement. Under the influence of gravity, the fish excrement will settle at the bottom of the collecting plate 3. Excess water will overflow through the collecting plate 3 and be filtered by the filter screen 4 to ensure the cleanliness of the water. The collecting plate 3 is located at the bottom of the cultivation plate 2. The roots of the seedlings inside the cultivation holes 14 will extend downward to absorb nutrients from the fish excrement inside the collecting plate 3, which is beneficial to the growth of the seedlings.
