Description

Technical Field

[0001] This utility model belongs to the field of rice-fish farming technology, specifically relating to an oxygen-enriched rice-fish farming ditch structure. Background Technology

[0002] Rice cultivation is an indispensable part of life in southern regions, as people cannot live without rice. The rice-fish farming model involves raising fish fry in rice paddies where rice seedlings have been planted. The rice paddy's ecosystem provides the means for the growth of small fish and shrimp, creating a micro-ecological cycle. This not only achieves a sustainable rice-fish farming system but also generates a considerable profit through the sale of the fish. The fish raised in the rice paddies can feed on insects and weeds, and their excrement also provides fertilizer for the rice, thus aiding its growth.

[0003] Currently, existing rice-fish farming methods typically involve digging fish ditches to meet the low water levels in the rice paddies. However, these ditches are usually only about half a meter deep. In summer, the water temperature rises due to intense sunlight, making it unsuitable for fish survival. Furthermore, the hot and humid weather and low air pressure in summer lead to low oxygen levels in the water, causing fish to constantly rise to the surface to suffocate and eventually die from oxygen deprivation. A current patent (CN219305758U) describes a rice-fish farming structure consisting of multiple rice paddies, embankments, and fish ditches. The embankments are rectangular and surround the outer edges of the rice paddies. The fish ditches are arranged in a cross shape inside the rice paddies, with deep water pits connected to both ends. Two symmetrically arranged pillars are fixedly connected to the embankments near the deep water pits, and fixed plates are fixedly connected to the tops of the pillars. The surfaces of the fixed plates have grooves for sliding... The trough is equipped with convex sliders, with a shade net fixedly connected to the top of the sliders and a pull rope fixedly connected to the bottom of the sliders. The shade net is placed above the deep water pit, and oxygen pumps are installed at both ends of the paddy field embankment. A controller is installed near the oxygen pumps on the embankment, and an oxygen content detector is installed in the controller. This reduces the impact of high temperatures on fish, protects the fish's growth environment, and prevents fish from dying from lack of oxygen. However, in actual use, there are still the following shortcomings: From a practical point of view, this patent lacks a comprehensive oxygen supply operation in the fish farming ditch, and the oxygen supply pipe is located in the fish farming ditch, which can easily affect the water quality in the ditch, which is not conducive to rice planting and aquaculture. At the same time, during the aquaculture process, it is impossible to provide shade protection for the upper part of the fish farming ditch. Since the water in the rice paddy is shallow, the water temperature can easily rise rapidly under sunlight, which is not conducive to fish farming.

[0004] Therefore, an oxygen-enriched rice-fish farming ditch structure is needed to solve the problems of inconvenience in providing comprehensive oxygenation and lack of shading and protection for the fish farming ditch in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide an oxygen-enriched rice-fish farming ditch structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oxygen-enriched paddy field fish farming ditch structure, comprising a paddy field embankment, an inlet channel, a drainage channel, and a fish farming ditch. The inlet channel and the drainage channel are respectively located on both sides of the paddy field embankment. Paddy fields are arranged within the paddy field embankment, and the fish farming ditch is located between the paddy fields. An oxygen supply mechanism is provided on the fish farming ditch, and a sunshade and protection mechanism is correspondingly provided above the fish farming ditch.

[0007] The sunshade and protection mechanism includes a connecting component and a protective component. The connecting component is located at the upper part of the fish farming ditch, and the protective component is located above the fish farming ditch via the connecting component.

[0008] It should be noted in the solution that the oxygen supply mechanism includes an aeration device, which is fixedly installed at the upper part of the fish farming ditch. A connecting pipe is connected to the aeration device, which is located at the bottom of the fish farming ditch. A branch pipe is connected to the connecting pipe, and an aeration disc is fixedly connected to the end of the branch pipe. The aeration disc is located in the fish farming ditch.

[0009] It is worth noting that multiple branch pipes are evenly spaced on the connecting pipe.

[0010] Furthermore, it should be noted that the connecting assembly includes a support frame, which is fixedly connected to the upper part of the fish farming ditch. A guide frame is fixedly connected to the support frame, and an installation platform is fixedly connected to the guide frame. A motor is fixedly installed on the top of the installation platform, and a drive gear is fixedly connected to the bottom of the motor. A driven gear is meshed on the outer side of the drive gear, and a rotating shaft is fixedly connected to the driven gear. A take-up roller is fixedly connected to the rotating shaft, and the take-up roller is located below the driven gear.

[0011] In a preferred embodiment, the support frame is arranged in a cross structure and is matched with the fish farming ditch.

[0012] In a preferred embodiment, four driven gears are disposed outside the driving gear, and the four driven gears are evenly distributed.

[0013] In a preferred embodiment, the protective assembly includes a sunshade net, a connecting rod, a slider, a cable, and a reset shaft. The reset shaft is rotatably connected to a support frame. The sunshade net is wound around the reset shaft. The outer side of the sunshade net is fixedly connected to the connecting rod. The slider is fixedly connected to both ends of the connecting rod and is slidably disposed on a guide frame. Both ends of the cable are connected to the connecting rod and the take-up roller, respectively.

[0014] Compared with the prior art, the oxygenated paddy field fish farming ditch structure provided by this utility model has at least the following beneficial effects:

[0015] (1) Through the oxygen supply mechanism, which is connected to the fish farming ditch and has multiple sets of branch pipes, it can provide oxygen to the water in the fish farming ditch in a more comprehensive way, thereby ensuring that the water is rich in oxygen, which is convenient for aquaculture, and at the same time, it avoids the pipes from rusting in the water and affecting the water quality.

[0016] (2) By setting up a shading and protection mechanism, the upper part of the fish farming ditch can be shaded and protected according to the weather during the breeding process, thereby effectively preventing the water temperature in the paddy field from being too high, making it easier for the fish to survive and improving the breeding efficiency.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides an oxygen-enriched paddy field fish farming ditch structure, including a paddy field ridge 1, an inlet ditch 2, a drainage ditch 3, and a fish farming ditch 4. The inlet ditch 2 and the drainage ditch 3 are respectively located on both sides of the paddy field ridge 1. A paddy field 101 is set inside the paddy field ridge 1. The fish farming ditch 4 is located between the paddy fields 101. An oxygen supply mechanism 5 is set on the fish farming ditch 4. A sunshade and protection mechanism 6 is set on the top of the fish farming ditch 4.

[0025] The sunshade and protection mechanism 6 includes a connecting component 61 and a protective component 62. The connecting component 61 is located on the upper part of the fish farming ditch 4, and the protective component 62 is located above the fish farming ditch 4 through the connecting component 61.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that the oxygen supply mechanism 5 includes an aeration device 501, which is fixedly installed on the upper part of the fish farming ditch 4. A connecting pipe 502 is connected to the aeration device 501. The connecting pipe 502 is located at the bottom of the fish farming ditch 4. A branch pipe 503 is connected to the connecting pipe 502. An aeration disc 504 is fixedly connected to the end of the branch pipe 503. The aeration disc 504 is located in the fish farming ditch 4. Multiple branch pipes 503 are evenly spaced on the connecting pipe 502.

[0027] When in use, the aeration device 501 is operated, and oxygen is aerated at the aeration disc 504 through the connecting pipe 502 and the branch pipe 503, so as to supply oxygen to the water body, which facilitates fish farming. The branch pipe 503 can improve the oxygen supply efficiency. At the same time, the connecting pipe 502 is buried at the bottom of the fish farming ditch 4 to avoid rusting after long-term use, thus ensuring the aquatic farming environment.

[0028] Specifically, the aeration device 501 uses a waterproof vortex aerator fan with a rated power of 800-1200W and an air output of ≥0.5m³. 3 / min, fixed inside the rainproof cover on the side wall of the field ridge 1, and connected to an external power supply or solar power system via a waterproof cable; the connecting pipe 502 and the branch pipe 503 are made of 304 stainless steel, with an epoxy resin anti-corrosion coating on the surface, and buried 10-15cm from the bottom of the fish farming ditch 4 to prevent fish from biting them.

[0029] As can be seen from the above working process, the oxygen supply mechanism 5, through the connecting pipes in the fish farming ditch 4 and the multiple sets of branch pipes 503, can provide a relatively comprehensive oxygen supply to the water in the fish farming ditch 4, thereby ensuring that the water is rich in oxygen, which is conducive to aquaculture, and at the same time, preventing the pipes from rusting in the water and affecting the water quality.

[0030] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the connecting component 61 includes a support frame 611, which is arranged in a cross structure and matches the fish farming ditch 4. The support frame 611 is fixedly connected to the upper part of the fish farming ditch 4. A guide frame 612 is fixedly connected to the support frame 611, and an installation platform 613 is fixedly connected to the guide frame 612. A motor 614 is fixedly installed on the top of the installation platform 613. A drive gear 615 is fixedly connected to the bottom of the motor 614. A driven gear 616 is meshed on the outside of the drive gear 615. A rotating shaft 617 is fixedly connected to the driven gear 616, and a take-up roller 618 is fixedly connected to the rotating shaft 617. The take-up roller 618 is located below the driven gear 616. Four driven gears 616 are arranged outside the drive gear 615, and the four driven gears 616 are evenly distributed.

[0031] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the protective component 62 includes a sunshade net 621, a connecting rod 622, a slider 623, a cable 624, and a reset shaft 625. The reset shaft 625 is rotatably connected to the support frame 611. The sunshade net 621 is wound around the reset shaft 625. The outer side of the sunshade net 621 is fixedly connected to the connecting rod 622. The slider 623 is fixedly connected to both ends of the connecting rod 622 and slides on the guide frame 612. The two ends of the cable 624 are connected to the connecting rod 622 and the take-up roller 618, respectively.

[0032] In use, the motor 614 operates, causing the drive gear 615 to rotate, which in turn drives the four driven gears 616 to rotate synchronously. This causes the take-up roller 618 to rotate and take in the cable 624. As the cable 624 winds around the take-up roller 618, it pulls the connecting rod 622 to slide within the guide frame 612 via the slider 623. This causes the shade net 621 to unwind on the reset shaft 625, forming a shade structure on the upper part of the fish farming ditch 4. This effectively prevents direct sunlight from causing the water temperature to become too high, thus facilitating fish survival and aquaculture. Furthermore, the reset shaft 625 allows for convenient winding of the shade net 621, improving the practicality of the device.

[0033] Specifically, cable 624 is made of nylon-coated stainless steel wire.

[0034] This scheme has the following working process: When this device is used, water is injected into the paddy field ridge 1 for rice planting and fish farming. The water is then stored in the fish farming ditch 4, where fish are raised. The aeration device 501 operates, providing oxygen to the aeration disc 504 through the connecting pipe 502 and branch pipe 503, thus facilitating fish farming. The branch pipe 503 further improves oxygen supply efficiency. Simultaneously, the connecting pipe 502 is buried at the bottom of the fish farming ditch 4 to prevent long-term corrosion, ensuring a safe aquatic environment. During the farming process, the motor 6... Operation 14 causes the drive gear 615 to rotate, which in turn drives the four driven gears 616 to rotate synchronously. This causes the take-up roller 618 to rotate and take in the cable 624. As the cable 624 winds around the take-up roller 618, it pulls the connecting rod 622 to slide within the guide frame 612 via the slider 623. This causes the shade net 621 to unwind on the reset shaft 625, forming a shade structure on the upper part of the fish farming ditch 4. This effectively prevents direct sunlight from causing the water temperature to become too high, thus facilitating fish survival and aquaculture. Furthermore, the reset shaft 625 allows for convenient winding of the shade net 621, improving the practicality of the device.

[0035] In summary: The oxygen supply mechanism 5, through the connecting pipes located within the fish farming ditch 4 and in conjunction with multiple sets of branch pipes 503, can provide comprehensive oxygenation to the water within the fish farming ditch 4, ensuring sufficient oxygen in the water for aquaculture and preventing corrosion of the pipes that could affect water quality. The shading and protection mechanism 6 can provide shading and protection to the upper part of the fish farming ditch 4 according to the weather during the aquaculture process, effectively preventing excessively high water temperatures in the paddy field 101, facilitating fish survival, and improving aquaculture efficiency.
