Description

Technical Field

[0001] This utility model belongs to the field of water conservation and unconventional water resource utilization technology, specifically relating to a crop irrigation device based on an aquaculture pond. Background Technology

[0002] Aquaculture ponds are specific aquatic facilities used for the artificial cultivation of aquatic organisms such as fish, shrimp, and shellfish. They typically achieve efficient aquaculture by artificially controlling environmental conditions such as water quality, water temperature, and dissolved oxygen levels.

[0003] The use of crop irrigation devices in aquaculture ponds is primarily aimed at addressing water quality, dissolved oxygen, and environmental stability issues by leveraging their water control advantages. Ultimately, this achieves cost reduction, efficiency improvement, and ecological protection. First, uniform water injection dilutes feces and uneaten feed, reducing harmful substances in the water and optimizing water quality. Second, the injection of water introduces air and breaks up water stratification, improving dissolved oxygen uniformity and meeting the respiration needs of the organisms. Third, precise water volume adjustment according to the aquaculture stage avoids fluctuations and ensures a stable growth environment.

[0004] Using crop irrigation devices in aquaculture ponds can reduce mortality and labor costs for farmers, and increase yield and efficiency. For the ecology, it can control pollutant concentrations, reduce the impact of wastewater on surrounding waters, and contribute to sustainable aquaculture.

[0005] The existing aquaculture ponds contain wastewater containing impurities such as nitrogen and phosphorus from fish and shrimp feces and the decomposition of uneaten feed. Direct discharge of this wastewater can easily pollute the surrounding water bodies, leading to agricultural non-point source pollution. Furthermore, unfiltered solid residues adhere to the roots of crops, affecting soil permeability. They may also generate localized high temperatures or harmful gases during decomposition, causing root hypoxia and rot, thus affecting crop growth. Utility Model Content

The other side of the pipe 8 is connected to the surface of the irrigation tank 9. The fine filter box 10 is fitted into the inner wall of the irrigation tank 9. The surface of the fine filter box 10 near the water inlet pipe 8 is bonded with a rubber tube 11. The inner wall of the fine filter box 10 is welded with a limiting bracket 12. The surface of the limiting bracket 12 is fitted with a sealing strip 13. The surface of the sealing strip 13 is bonded to the surface of the coarse filter 14. The surface of the coarse filter 14 is inserted into the surface of the limiting bracket 12. The surface of the limiting bracket 12 is inserted into the middle filter 15. The surface of the middle filter 15 is bonded with the sealing strip 13.

[0027] Preferably, the inner wall surface of the protective net 5 has a threaded groove, the shape and size of which are adapted to the threaded structure on the surface of the connecting pipe 4.

[0028] In practical use, the connecting pipe 4 connected to the bottom of the aquaculture pond body 1 is threaded with a protective net 5 on the inlet end side of the inner wall of the aquaculture pond body 1 to intercept the fish and shrimp in the aquaculture pond body 1. Therefore, when using it, the protective net 5 with an appropriate mesh size can be selected according to the size of the fish and shrimp raised in the aquaculture pond body 1.

[0029] Preferably, the limiting bracket 12 is a U-shaped integrated structure, with two sets of limiting brackets 12 symmetrically distributed on the inner wall surface of the fine filter box 10. The rectangular cavity shape and size of the limiting bracket 12 surface are adapted to the coarse filter 14 and the medium filter 15.

[0030] In actual use, two sets of limiting brackets 12 welded inside the irrigation tank 9 are connected in sequence with coarse filter screen 14 and coarse filter screen 14.

[0031] Preferably, the top surface of the sealing strip 13 abuts against the sealing gasket 16, the top surface of the sealing gasket 16 is bonded to the bottom of the box cover 17, the box cover 17 is fitted and connected to the top opening end of the irrigation box 9, and the front surface of the box cover 17 is welded with the insert block 18.

[0032] In practical use, the sealing gasket 16, which is attached to the bottom of the cover 17, abuts against the top of the sealing strip 13, the coarse filter 14 and the medium filter 15, thereby filling the gaps where the three meet the fine filter box 10.

[0033] Preferably, a slot 19 is formed on the surface of the insert block 18, a plug rod 20 is inserted into the surface of the slot 19, a threaded head 21 is threadedly connected to the threaded end surface of the plug rod 20, and the surface of the threaded head 21 abuts against the surface of the base 22.

[0034] In practical use, the insert rod 20, which is threaded onto the threaded head 21, is periodically unscrewed to pull out the insert rod 20 that is inserted between the insert block 18 and the base 22.

[0035] Preferably, the inner wall surface of the base 22 is fitted with the insert block 18, the surface of the base 22 is welded to the front end of the irrigation tank 9, the back surface of the tank cover 17 is welded with the side block 23, and the surface of the side block 23 is rotatably connected to the fixing block 25 by means of the rotating shaft 24.

[0036] In practical use, the lid 17 is rotated upwards using the pivot 24 connected to the other side of the lid 17 to expose the covered fine filter box 10, coarse filter 14 and medium filter 15.

[0037] Preferably, the fixing block 25 is welded to the surface of the irrigation tank 9, the lower end surface of the irrigation tank 9 is connected to the drain pipe 26, and the surface of the drain pipe 26 is threadedly connected to the third ball valve 27.

[0038] In practical use, the irrigation tank 9 is connected to an external irrigation nozzle via a drain pipe 26 and a third ball valve 27 on the other side, thereby irrigating the crops.

[0039] Working principle: When using the aquaculture pond 1 for fish and shrimp farming, an external water source is connected through the inlet pipe 2 and the first ball valve 3 to control the water supply and exchange within the aquaculture pond 1. Simultaneously, a protective net 5 is threaded onto the inlet side of the connecting pipe 4 at the bottom of the aquaculture pond 1, which intercepts the fish and shrimp within the pond. Therefore, the size of the protective net 5 can be selected according to the size of the fish and shrimp being farmed in the pond. During aquaculture in the pond, the liquid flow meter 6 is connected to the controller, which in turn is connected to the actuators of the first ball valve 3 and the second ball valve 7. A target flow rate is set. When the liquid flow meter 6 detects that the wastewater flow rate discharged from the aquaculture pond 1 exceeds the target flow rate, the controller sends a signal to the actuator of the second ball valve 7 to reduce the opening of the second ball valve 7. When the flow rate is lower than the target flow rate, the opening of the second ball valve 7 is increased, thus achieving stable drainage.

[0040] Through the above method, wastewater from the bottom of the aquaculture pond 1 is discharged into the irrigation tank 9. Simultaneously, a fine filter box 10 with a mesh structure is fitted into the inner wall of the irrigation tank 9. Its outlet near the inlet pipe 8 abuts against the inlet of the rubber hose 11, allowing wastewater from the aquaculture pond 1 to be discharged into the irrigation tank 9. Two sets of limiting brackets 12 welded inside the irrigation tank 9 are sequentially fitted with coarse filters 14. At the same time, an "L"-shaped silicone rubber sealing gasket 16 is fitted over the gaps where the coarse and medium filters 14 intersect with the limiting brackets 12, thus filling the gaps between the limiting brackets 12 and the coarse and medium filters 14. Based on the particle size of solid impurities in the aquaculture pond 1, fine filter boxes 10, coarse filters 14, and medium filters 15 with appropriate mesh sizes are selected, with the coarse filter 14 having a mesh size of 1. The coarse filter 14 has a mesh size of 0.0-2.0mm, which prioritizes filtering larger solid impurities in the wastewater, reducing the filtration pressure on the subsequent medium filter 15 and fine filter box 10, preventing large impurities from directly clogging the fine pores, and extending the overall filter cleaning cycle. The medium filter 15 has a mesh size of 0.2-0.5mm, which filters out small uneaten food debris, dispersed fish and shrimp feces particles (0.1-0.5mm in diameter) and suspended flocculent impurities in the water that were not intercepted by the coarse filter 14, preventing medium-sized impurities from entering the fine filter box 10 and preventing the fine filter box 10 from affecting the water flow speed due to excessive accumulation of impurities. The fine filter box 10 has a mesh size of 0.05-0.1mm, which filters out small particles (such as feces fragments and small uneaten food residue) remaining in the medium filter 15, ensuring that the wastewater finally entering the irrigation system is free of obvious solid impurities and preventing clogging of precision irrigation components such as drip irrigation tape and sprinklers.

[0041] Then, the irrigation tank 9 is connected to the external irrigation nozzles via the drain pipe 26 and the third ball valve 27 on the other side, thereby irrigating the crops. The insert 20, which is threaded onto the threaded head 21, can be unscrewed periodically to pull out the insert 20 inserted between the insert block 18 and the base 22. Then, the tank cover 17 is rotated upwards using the pivot 24 connected to the other side of the cover 17 to expose the covered fine filter box 10, coarse filter 14, and medium filter 15. By lifting the fine filter box 10 as a whole, the solid impurities such as fish and shrimp feces and uneaten feed intercepted inside are mixed with auxiliary materials such as straw and dead branches. After composting and fermentation (controlled temperature and humidity, about 1-2 months), harmful substances are decomposed to form organic fertilizer, which is then used to benefit the crops and save some of the cost of purchasing chemical fertilizers.

[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
