Technical Field

[0001] The utility model relates to the technical field of planting beds, in particular to a drainage structure for a fish-vegetable co-cultivation planting bed. Background Art

[0002] Fish-vegetable co-cultivation, also known as fish-vegetable symbiosis, is a new type of composite farming system. It combines two completely different technologies, aquaculture and hydroponics, through ingenious ecological design to achieve scientific symbiotic coexistence. This technology adopts the concept of "solving ecological problems ecologically", combines the biochemical system and the planting system, and utilizes the characteristics of nutrient regulation, degradation, and slow release of minerals to optimize the self-regulating function of the system, so that the system maintains nutrient balance and truly realizes "raising fish without changing water and growing vegetables without fertilizing".

[0003] Traditional planting beds mostly adopt the hydroponic or ceramsite cultivation mode, and the water outlet mode adopts the overflow mode. The main problems are poor microbial film formation effect, ineffective interception of water body nutrients, and the planting bed cannot effectively utilize the nutrients in the water body. At the same time, sewage reflux will also cause the ammonia nitrogen and nitrite in the aquaculture pond to generally exceed the standard, thus affecting the normal growth of aquaculture.

[0004] Therefore, it is necessary to develop a drainage structure for a fish-vegetable co-cultivation planting bed to address the above defects. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a drainage structure for a fish-vegetable co-cultivation planting bed, so that the planting bed can effectively intercept water body nutrients and particulate matter, and at the same time, the return of clean water improves the quality of aquaculture.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The drainage structure of the fish-vegetable co-cultivation planting bed of the utility model is applied to the drainage of the planting bin, and includes a drainage guard, a return water pipe, a central pipe, and a drain pipe; the drain pipe for returning water to the fish pond is horizontally arranged below the planting bin, and the bottom end of the vertically arranged central pipe is connected to the top end of the drain pipe and extends into the planting bin; the drainage guard is arranged in the planting bin and vertically coaxially covers the outside of the central pipe, the return water pipe is horizontally laid at the bottom of the planting bin, one end of the return water pipe is closed and the other end is connected to the bottom of the drainage guard; a plurality of water permeable holes are uniformly arranged on the side walls of the return water pipe and the drainage guard.

[0008] Further, coarse filler and fine filler are arranged in the planting bin; the coarse filler is arranged on one side and the bottom of the fine filler, and the coarse filler is filled outside the return water pipe and the drainage guard; the particle diameter of the coarse filler is larger than the diameter of the water permeable holes.

[0009] Further, it further includes a siphon protection tube, the siphon protection tube coaxially covers between the central tube and the drainage protection cover, and the top opening of the siphon protection tube is higher than the top end of the central tube and lower than the top opening of the drainage protection cover.

[0010] Further, the top opening of the drainage protection cover is threadedly connected with a top cover.

[0011] Further, it further includes a cleaning component, the cleaning component is arranged on the return water pipe and can clean the inner wall of the return water pipe.

[0012] Further, the cleaning component includes a cleaning ball and a pulling rope. The distal end of the return water pipe seals and extends out of the side wall of the planting bin and is provided with a detachable end cover; the cleaning ball is arranged in the drainage protection cover, the cleaning ball is connected to a rope loop at the inner end of the end cover through the pulling rope, and the cleaning ball is made of an extrudable flexible material.

[0013] Further, both ends of the cleaning ball are provided with rope buckles, and the rope buckle at the other end away from the pulling rope is used for tying a spare rope.

[0014] Further, the return water pipe is specifically made of a corrugated pipe.

[0015] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0016] In the drainage structure of the fish-vegetable co-cultivation planting bed of the present utility model, by setting the return water pipe and the drainage protection cover as water-permeable components, only the water passing through the water-permeable holes can be collected into the central pipe and the drainage pipe and discharged, the water body is filtered, and the particulate matters and nutrients are intercepted in the planting bin and absorbed and utilized in the vegetable production process. Through the horizontally arranged return water pipe, a recovery channel can be set at the entire bottom of the planting bin, avoiding the over-concentration of the filtration interception in a local area.

[0017] In addition, through the reasonable distribution of the coarse filler and the fine filler, the water body can be filtered and intercepted by the filler. At the same time, the coarse filler contacts the outer wall of the return pipe and the drainage shield, avoiding the blockage of the water permeable holes and ensuring smooth drainage. The return pipe made of corrugated pipe is buried in the coarse filler, which has good holding force, is not easy to loosen and come out, and has good flexibility, facilitating arbitrary rotation and bending along the direction of the planting bin. Through the setting of the siphon protection pipe, a full water state can be formed at the top of the central pipe, and drainage can be carried out using the siphon effect.

After removal, the internal situation can be observed, which is convenient for maintenance. By setting a cleaning component to clean the inner wall of the return pipe, the conjunctiva and sundries on the inner side of the pipe wall can be removed, avoiding pipeline blockage and making the return water smooth. By leaving an outer port of the return pipe outside the side wall of the planting bin, it is convenient for the dirt to be directly discharged outside the planting bin during cleaning and is also convenient for operation. By using the method that the cleaning ball passes through the inner cavity of the return pipe throughout the process, the whole process can be cleaned without dead corners. By respectively setting rope tying buckles at both ends of the cleaning ball, before cleaning, the spare rope is tied to the rope tying buckle at the other end far from the pulling rope. When pulling out the cleaning ball from the end cover to complete the cleaning process, the spare rope is also reinserted into the return pipe, and the removed cleaning ball is tied well again inside the drainage shield to prepare for the next cleaning.

[0025] Embodiment 1

[0026] As Figure 1 and Figure 2 shown, the drainage structure of the fish-vegetable co-cultivation planting bed of the present utility model is applied to the drainage of the planting bin 11, and includes a drainage shield 1, a return water pipe 2, a central pipe 4, and a drain pipe 5. The drain pipe 5 for returning water to the fish pond is horizontally arranged below the planting bin 11, and the drain pipe 5 is not provided with a drainage slope. The bottom end of the vertically arranged central pipe 4 is connected to the drain pipe 5, and the top end of the central pipe 4 extends into the planting bin 11. The drainage shield 1 is arranged in the planting bin 11 and vertically coaxially covers the outside of the central pipe 4. The return water pipe 2 is horizontally laid at the bottom of the planting bin 11, and one end of the return water pipe 2 is closed and the other end is connected to the bottom of the drainage shield 1. A plurality of water permeable holes are evenly arranged on the side walls of the return water pipe 2 and the drainage shield 1.

[0027] By setting the return water pipe 2 and the drainage shield 1 as water permeable components, only the water passing through the water permeable holes can be collected and discharged through the central pipe 4 and the drain pipe 5, the water body is filtered, and the particulate matter and nutrients are intercepted in the planting bin 11 and absorbed and utilized in the vegetable production process. Through the horizontally arranged return water pipe 2, a recovery channel can be set at the entire bottom of the planting bin 11 to avoid excessive concentration of the filtration interception in a local area.

[0028] In a specific implementation manner of this embodiment, as Figure 1 and Figure 2 shown, a coarse filler 9 and a fine filler 10 are arranged in the planting bin 11. The coarse filler 9 and the fine filler 10 are ceramsites with different particle sizes. The coarse filler 9 is arranged on one side and the bottom of the fine filler 10. The coarse filler 9 is filled outside the return water pipe 2 and the drainage shield 1, and vegetables are planted in the area of the fine filler 10. The particle diameter of the coarse filler 9 is larger than the diameter of the water permeable holes.

[0029] Specifically, asFigure 1 As shown, the return water pipe 2 is specifically made of corrugated pipe.

[0030] Through the reasonable distribution of the coarse filler 9 and the fine filler 10, the water body can be filtered and intercepted by the filler. At the same time, the coarse filler 9 contacts the outer walls of the return water pipe 2 and the drainage protection cover 1, avoiding clogging of the water permeable holes and ensuring smooth drainage. The return water pipe 2 made of corrugated pipe is buried in the coarse filler 9, having good holding force, not easy to loosen and come out, and having good flexibility, which is convenient for arbitrary rotation and bending along the direction of the planting bin 11.

[0031] In a specific embodiment of this embodiment, as Figure 2 shown, the drainage structure of the fish-vegetable co-cultivation planting bed of the present utility model further includes a siphon protection pipe 3. The siphon protection pipe 3 coaxially covers between the central pipe 4 and the drainage protection cover 1, and the top opening of the siphon protection pipe 3 is higher than the top end of the central pipe 4 and lower than the top opening of the drainage protection cover 1.

[0032] Through the setting of the siphon protection pipe 3, a full water state can be formed at the top end of the central pipe 4, and drainage can be carried out by using the siphon effect. Drainage with pressure can improve the drainage flow rate and reduce the situation of pipeline blockage.

[0033] In a specific embodiment of this embodiment, as Figure 1 and Figure 2 described, the top opening of the drainage protection cover 1 is threadedly connected with a top cover 101, that is, the connection between the top cover 101 and the drainage protection cover 1 is detachable.

[0034] By providing a detachable top cover 101 at the top of the drainage protection cover 1, it can usually block the top opening to prevent the filler from rolling in, and after being taken out, the internal situation can be observed, which is convenient for maintenance.

[0035] In the drainage process of this embodiment, the water entering the planting bin 11 is the water body flowing out of the fish pond. It passes through the fine filler 10 and the coarse filler 9 from top to bottom. The nutrients and particulate matters in the water body can be completely adsorbed by the filler, and then decomposed and transformed by microorganisms to form nitrates that can be absorbed by plants. The filtered water body enters the inner cavity of the return water pipe 2 through the water permeable holes of the return water pipe 2 and further flows back into the drainage protection cover 1. When the water level in the drainage protection cover 1 rises and exceeds the siphon protection pipe 3, the siphon protection pipe 3 is filled. When drainage is required, the water valve at the end of the drain pipe 5 is opened. At this time, the central pipe 4 and the drain pipe 5 are in a full water state. Due to the siphon drainage effect, a relatively large drainage pressure can be obtained, and it is not easy to block the central pipe 4 and the drain pipe 5.

[0036] Embodiment 2

[0037] As Figure 2As shown, after long-term operation, it is easy for the inner wall of the return pipe 2 to form a film and become blocked, affecting the normal return water. To solve the above problems, the applicant made improvements on the basis of Embodiment 1 to form this embodiment. The drainage structure of the fish-vegetable co-cultivation planting bed of the present utility model further includes a cleaning component, and the cleaning component is arranged on the return pipe 2 and can clean the inner wall of the return pipe 2.

[0038] Specifically, as Figure 2 shown, the cleaning component includes a cleaning ball 8 and a pull rope 7. The distal end of the return pipe 2 extends out of the side wall of the planting bin 11 in a sealed manner and is provided with a detachable end cap 6. The end cap 6 can be sealed on the distal end port of the return pipe 2 by means of threaded connection. The cleaning ball 8 is arranged in the drainage shield 1. The cleaning ball 8 is connected to the rope loop 601 at the inner end of the end cap 6 through the pull rope 7. The rope loop 601 is made of a plastic rope that is not easily corroded and passes through the entire return pipe 2. The cleaning ball 8 is made of an extrudable flexible material, such as an airbag structure with hairs, and the outer diameter of the airbag is larger than the inner diameter of the return pipe 2 under normal conditions.

[0039] By arranging the cleaning component to clean the inner wall of the return pipe 2, the film and sundries on the inner side of the pipe wall can be removed, avoiding pipe blockage and making the return water smooth. By leaving the outer port of the return pipe 2 outside the side wall of the planting bin 11, it is convenient for the dirt to be directly discharged outside the planting bin 11 during cleaning and also convenient for operation. By using the method that the cleaning ball 8 passes through the inner cavity of the return pipe 2 throughout the process, the whole process can be cleaned without dead corners.

[0040] In a specific implementation manner of this embodiment, as Figure 2 shown, rope buckles are arranged at both ends of the cleaning ball 8, and the rope buckle at the other end far from the pull rope 7 is used for tying the spare rope.

[0041] By arranging rope buckles at both ends of the cleaning ball 8 respectively, before cleaning, the spare rope is tied to the rope buckle at the other end far from the pull rope 7. When pulling out the cleaning ball 8 from the end cap 6 during the cleaning process, the spare rope is also reinserted into the return pipe 2, and the removed cleaning ball 8 is tied well in the drainage shield 1 again to prepare for the next cleaning.

[0042] Working process of this embodiment: When it is found that the drainage in the drainage shield 1 is not smooth and the drainage cycle is long, the return pipe 2 needs to be cleaned. Stop the water inlet of the planting bin 11. Before cleaning, open the top cover 101 and tie one end of the spare rope to the rope tying buckle far away from the other end of the pulling rope 7. Before removing the end cover 6, place a sewage collection bucket under the end cover 6, unscrew the end cover 6, untie the end of the pulling rope 7 from the rope tying ring 601, and pull the end of the pulling rope 7. The cleaning ball 8 is pulled by the pulling rope 7 and enters the inner port of the return pipe 2 from the bottom of the drainage shield 1. Continuously pull the pulling rope 7, and the cleaning ball 8 scrapes and walks the whole journey in the return pipe 2, continuously hanging off the conjunctiva and sundries on the pipe wall and pushing them towards the outer port. The sewage flows out from the outer port and enters the sewage collection bucket. Untie the cleaning ball 8 from the spare rope, tie the outer end of the spare rope to the rope tying ring 601 again, and screw the end cover 6 back on tightly. After the cleaning ball 8 is cleaned separately, reconnect it to one end of the spare rope located inside the drainage shield 1 for future use. Open the water inlet of the planting bin 11 and observe whether the drainage situation has improved.

[0043] In summary, for the drainage structure of the practical fish-vegetable co-cultivation planting bed, by setting the return pipe 2 and the drainage shield 1 as permeable components, only the water passing through the permeable holes can be collected into the central pipe 4 and the drain pipe 5 for drainage. The water body is filtered, and the particulate matter and nutrients are intercepted in the planting bin 11 and absorbed and utilized during the vegetable production process. Through the horizontally arranged return pipe 2, a recycling channel can be set at the entire bottom of the planting bin 11 to avoid excessive concentration of the filtered interception in a local area. In addition, through the reasonable distribution of the coarse filler 9 and the fine filler 10, the water body can be filtered and intercepted by the filler. At the same time, the coarse filler 9 is in contact with the outer walls of the return pipe 2 and the drainage shield 1, avoiding blockage of the permeable holes and ensuring smooth drainage. The return pipe 2 made of corrugated pipe is buried in the coarse filler 9, has good holding force, is not easy to loosen and come out, and has good flexibility, facilitating arbitrary rotation and bending along with the direction of the planting bin 11. Through the setting of the siphon protection pipe 3, a full water state can be formed at the top end of the central pipe 4, and drainage can be carried out by using the siphon effect. The pressurized drainage can improve the drainage flow rate and reduce the pipeline blockage situation. By setting a detachable top cover 101 at the top of the drainage shield 1, the top opening can be blocked usually to prevent the filler from rolling in, and the internal situation can be observed after it is taken out, which is convenient for maintenance. By setting a cleaning component to clean the inner wall of the return pipe 2, the conjunctiva and sundries on the inner side of the pipe wall can be removed, avoiding pipeline blockage and making the return water smooth. By leaving an outer port of the return pipe 2 outside the side wall of the planting bin 11, it is convenient for the dirt to be directly discharged outside the planting bin 11 during cleaning and also convenient for operation. By using the method that the cleaning ball 8 passes through the inner cavity of the return pipe 2 throughout the whole process, the whole process can be cleaned without dead corners. By respectively setting rope tying buckles at both ends of the cleaning ball 8, before cleaning, tie the spare rope to the rope tying buckle far away from the other end of the pulling rope 7. When pulling out the cleaning ball 8 from the end cover 6 during the cleaning process, the spare rope is also reinserted into the return pipe 2, and the removed cleaning ball 8 is tied well inside the drainage shield 1 again to prepare for the next cleaning.
