Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a fish-vegetable symbiotic circulating water purification device. Background Art

[0002] Aquaponics is a novel, compound farming system that combines two fundamentally different agricultural techniques, aquaculture and hydroponics, through ingenious ecological design to achieve a scientific, synergistic symbiosis. This allows fish to be raised without water quality changes and vegetables to grow normally without fertilizer. The aquaponics system consists of two subsystems: aquaculture and vegetable cultivation. In the aquaculture subsystem, fish waste is converted into nutrients beneficial to plants. In the vegetable cultivation subsystem, plants absorb these nutrients through their roots, simultaneously purifying the water.

[0003] Although plants can purify water through their roots, their purification effect is limited. Therefore, existing fish-vegetable symbiotic equipment must also be equipped with purification equipment, which can be used to purify water. However, when the existing purification equipment is in use, it mainly relies on the filter material installed inside to purify the water. The filter material has a certain service life and needs to be replaced regularly. However, the existing purification equipment has the problem of being inconvenient to replace the filter material. In view of this, we propose a fish-vegetable symbiotic circulating water purification device. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] This embodiment provides a technical solution:

[0030] See also Figures 1-6As shown, a fish-vegetable symbiotic circulating water purification device comprises a fish pond 1 with an opening at the top, a tray 2 is provided above the fish pond 1, a fixing frame 20 is fixed to the top opening of the tray 2, a plurality of grooves 201 for growing vegetables are provided on the top of the fixing frame 20, and a water leakage hole 202 is provided inside the groove 201; a purification unit 3 is installed above the front end of the fish pond 1, and the purification unit 3 comprises a box body 30 with an opening at the front end face, an input pipe 301 and an output pipe 302 are respectively provided at the upper and lower ends of the box body 30, and the input pipe 301 and the output pipe 302 are respectively connected to the tray 2 and the fish pond 1; a cross bar 31 is fixed to the bottom of the front end face of the box body 30, a sliding cavity 311 is provided at both ends of the cross bar 31, and a notch penetrating the cross bar 31 is provided between the two sliding cavities 311; a notch between the two sliding cavities 311 The top of the box body 35 is provided with a drainage groove 351, and a hollow support net 352 is fixed in the drainage groove 351; a plurality of filter layers 36 are provided in the top opening of the box body 35 from top to bottom; a connecting plate 38 is fixed to the front end of the box body 35, and a through groove 381 is provided at the bottom end of the connecting plate 38. The cross bar 31 passes through the through groove 381, and the limit block 34 is pressed against the front end surface of the connecting plate 38.

[0031] Furthermore, a water pump 11 is installed at the inner bottom of the fish pond 1. A connecting pipe 12 is installed at the water outlet of the water pump 11. The connecting pipe 12 passes through the outer wall of the fish pond 1. A horizontal pipe 22 is provided above the tray 2 and is connected to the connecting pipe 12. A plurality of nozzles 23 are installed at the bottom of the horizontal pipe 22. The water source in the fish pond 1 is transported to the horizontal pipe 22 through the water pump 11 and the connecting pipe 12, and the vegetables planted in the groove 201 are watered through the nozzles 23.

[0032] In this embodiment, the top of the tray 2 is fixed with side panels 21 at both the front and rear ends, and the cross tube 22 is fixedly connected to the side panels 21 by bolts. The side panels 21 support and fix the cross tube 22, ensuring the installation stability of the cross tube 22.

[0033] In this embodiment, the front end surface of the connecting plate 38 is fixedly connected to two handles 37 by bolts, and the overall shape of the handle 37 is U-shaped. The setting of the handle 37 is convenient for gripping, thereby facilitating the disassembly and assembly of the connecting plate 38 and the box body 35.

[0034] In this embodiment, support plates 13 are installed at both ends of the fish pond 1 and the tray 2, and the support plates 13 are fixedly connected to the fish pond 1 and the tray 2 by bolts. The support plates 13 play a role in stably connecting and fixing the fish pond 1 and the tray 2.

[0035] In this embodiment, a protective cover 10 is bolted to the inner bottom of the fish pond 1 outside the water pump 11. A connection groove is formed on the front surface of the protective cover 10, and a filter 101 is fixed to the connection groove. The provision of the filter 101 can prevent large foreign matter from entering the connecting pipe 12, thereby preventing the connecting pipe 12 from being blocked.

[0036] In this embodiment, the plurality of grooves 201 are arranged in a matrix, and the cross-section of the grooves 201 is funnel-shaped. The matrix-shaped design improves space utilization, while the funnel-shaped cross-section design facilitates the concentration and penetration of water and fertilizer, promoting the absorption and growth of plant roots.

[0037] In this embodiment, the center of the double-ended screw 33 is coaxially keyed to the adjustment column 32, and the outer wall of the adjustment column 32 is provided with multiple anti-slip grooves. The anti-slip grooves can increase the friction between the hand and the adjustment column 32, thereby facilitating the rotation of the double-ended screw 33 by rotating the adjustment column 32.

[0038] It can be understood that the multiple filter layers 36 in this embodiment are sand, medical stone, bio balls, filter cotton and activated carbon from top to bottom. Sand, medical stone, bio balls, filter cotton and activated carbon all have a better filtering effect on the water source. The use of multiple materials can improve the filtering effect of the filter layer 36 on the water source.

[0039] It should be added that the ends of the double-ended screw 33 are coaxially fixed with limit blocks 34, and the thread winding directions of the two ends of the double-ended screw 33 are opposite; when the double-ended screw 33 rotates, the limit blocks 34 on both sides can move synchronously relative to each other, thereby facilitating the limiting of the connecting plate 38 by the limit blocks 34; and the setting of the limit blocks 34 can prevent the double-ended screw 33 from detaching from the limit blocks 34.

[0040] When the filter layer 36 needs to be replaced, the user first rotates the adjusting column 32, and the adjusting column 32 drives the double-headed screw 33 to rotate. As the double-headed screw 33 rotates, the limit blocks 34 on both sides move synchronously inward relative to each other, and the limit blocks 34 slide along the sliding cavity 311. When the limit blocks 34 retract into the sliding cavity 311, the rotation of the adjusting column 32 is stopped. The user then holds the handle 37 and pulls it forward. The handle 37 drives the connecting plate 38 and the box body 35 to detach from the box body 30. Finally, the user pours out multiple filter layers 36 and replaces them.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
