Abstract
Description
Technical Field
[0001] The invention relates to the technical field of regulating the concentration of nitrogen and phosphorus nutrient solution in farmland water, in particular to a device for regulating the nitrogen and phosphorus concentration of farmland water in a farmland wetland. Background Art
[0002] Farmland wetlands consist of multiple separate planting areas, each of which usually has aquatic crops planted in it, meaning that the roots of these crops are immersed in farmland water. To ensure the normal growth of aquatic crops, farmers put nitrogen and phosphorus fertilizers into farmland water, which are dissolved into nitrogen and phosphorus nutrient solutions by farmland water, and the nitrogen and phosphorus nutrient solutions promote the growth of aquatic crops.
[0003] However, farmers cannot control the amount of nitrogen and phosphorus fertilizers they apply. When too much nitrogen and phosphorus fertilizers are applied, the concentration of the corresponding nitrogen and phosphorus nutrient solution also increases. However, nitrogen and phosphorus nutrient solution with excessive concentration will affect the normal growth of aquatic crops.
[0004] To this end, farmers will place a Figure 1~Figure 3 The nitrogen-phosphorus concentration regulating device shown is used to regulate the concentration of the nitrogen-phosphorus nutrient solution, and the nitrogen-phosphorus concentration regulating device comprises a rectangular shell 1 with an opening on the top, a net basket 4 placed in the inner cavity of the rectangular shell 1 and supported on the bottom surface of the rectangular shell 1, a plurality of support frames 13 are fixedly arranged on the bottom surface of the rectangular shell 1, a plurality of liquid holes 2 connected with the inner cavity of the rectangular shell 1 are opened on the outer wall of the rectangular shell 1, the top of the net basket 4 is provided with an opening, the bottom of the net basket 4 is closed, and a layer of microbial particles is contained in the net basket 4.
[0005] The method of the nitrogen and phosphorus concentration regulating device for regulating the concentration of nitrogen and phosphorus nutrient solution in farmland water is: S1. The farmer supports the support frame 13 of the nitrogen and phosphorus concentration regulating device on the soil layer of the planting area. At this time, the farmland water in the planting area sequentially passes through the liquid holes 2 of the rectangular shell 1 and the mesh holes of the net basket 4, and finally immerses the microbial particles; S2. Farmers put nitrogen and phosphorus fertilizers into farmland water, and farmland water dissolves nitrogen and phosphorus fertilizers into nitrogen and phosphorus nutrient solution, which promotes the growth of aquatic crops; When too much nitrogen and phosphorus fertilizers are applied, the concentration of the corresponding nitrogen and phosphorus nutrient solution also increases. At this time, the microbial particles absorb part of the nitrogen and phosphorus nutrient solution on them, thereby reducing the concentration of the nitrogen and phosphorus nutrient solution and making the concentration of the nitrogen and phosphorus nutrient solution reach a normal level; when the concentration of the nitrogen and phosphorus nutrient solution in the farmland water is lower than the normal level, the microbial particles will release the nitrogen and phosphorus nutrient solution adsorbed on them into the farmland water to make the concentration of the nitrogen and phosphorus nutrient solution reach a normal level again, thereby achieving the regulation of the concentration of the nitrogen and phosphorus nutrient solution in the farmland water, and then promoting the normal growth of aquatic crops.
[0006] After the nitrogen and phosphorus concentration regulating device has been used for a period of time, a large amount of sludge will also adhere to the microbial particles [because the sludge will come into contact with the microbial particles along with the farmland water], and the sludge will affect the normal work of the microbial particles. For this reason, farmers need to clean the microbial particles regularly. The method for farmers to clean the microbial particles is: S3, the farmer takes out the net basket 4 containing the microbial particles from the rectangular shell 1, and then the farmer moves the net basket 4 to the outer slope of the planting area; S4. Farmers use the clean water sprayed from the nozzle to wash the microbial particles. After a period of time, the sludge attached to the microbial particles can be washed away; S5. After the cleaning of the microbial particles is completed, the farmer puts the net basket 4 back into the rectangular shell 1, so that the microbial particles continue to work.
[0007] However, although this nitrogen and phosphorus concentration regulating device can regulate the concentration of nitrogen and phosphorus nutrient solution in farmland water, it still has the following technical defects in actual use: I. In steps S4-S5, when the microbial particles need to be cleaned regularly, the net basket 4 needs to be manually taken out of the rectangular shell 1, and then the net basket 4 is moved to the outer slope of the planting area before the microbial particles can be rinsed through the nozzle; after cleaning, the net basket 4 needs to be manually moved from the outer slope to the location of the rectangular shell 1, and then the net basket 4 is placed into the rectangular shell 1; and the distance from the rectangular shell 1 to the outer slope of the planting area is relatively long, and the long-distance manual back and forth transportation of the net basket 4 delays the cleaning of the microbial particles, thereby reducing the cleaning efficiency of the microbial particles.
[0008] II. In step S4, the nozzle needs to be manually operated to wash the microbial particles, which undoubtedly increases the workload of washing the microbial particles.
[0009] Therefore, there is an urgent need for a farmland water nitrogen and phosphorus concentration regulating device that can reduce the workload of cleaning microbial particles and greatly improve the cleaning efficiency of microbial particles. Summary of the invention
[0010] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a device for regulating nitrogen and phosphorus concentrations in farmland water of farmland wetlands, which reduces the workload of cleaning microbial particles and greatly improves the cleaning efficiency of microbial particles.

DETAILED DESCRIPTION
[0020] The present invention is further described below in conjunction with the accompanying drawings, and the protection scope of the present invention is not limited to the following: like Figure 5~Figure 9 As shown, a device for regulating nitrogen and phosphorus concentrations in farmland water of a farmland wetland comprises a rectangular shell 1 with an opening on the top, a plurality of liquid holes 2 connected with the inner cavity of the rectangular shell 1 are opened on the outer wall of the rectangular shell 1, a lifting plate 3 supported on the bottom wall of the rectangular shell 1 is placed in the inner cavity of the rectangular shell 1, a net basket 4 with an opening on the top is placed on the top surface of the lifting plate 3; a plurality of support frames 13 are fixedly arranged on the bottom surface of the rectangular shell 1.
[0021] Vertical plates are welded on the left and right outer walls of the rectangular shell 1, and a connecting plate 5 is welded between the two vertical plates. Vertical screw nut pairs 6 are arranged on the connecting plate 5 and on the left and right sides thereof. The two vertical screw nut pairs 6 are arranged symmetrically on the left and right sides. A rod 7 is welded on the bottom surface of the nut 15 of the two vertical screw nut pairs 6. The rod 7 passes through the inner cavity of the rectangular shell 1 and the inner cavity of the net basket 4 in sequence downward, and is finally welded on the top surface of the lifting plate 3. The net basket 4 contains a layer of microbial particles, and the size of the microbial particles is larger than the size of the mesh of the net basket 4. Therefore, the microbial particles will not fall from the mesh of the net basket 4. The vertical screw nut pair 6 on the left side includes a screw 14 rotatably mounted on the connecting plate 5, a nut 15 threadedly connected to the screw 14, and a light rod welded on the bottom surface of the connecting plate 5. A through hole is opened in the nut 15, and the nut 15 is sleeved on the light rod through the through hole. A hand wheel 16 is connected to the top of the screw 14.
[0022] A water pump 8 and a main pipe 9 are installed on the top surface of the connecting plate 5. The water inlet of the water pump 8 is connected to the clean water tank via a hose 10, and the water outlet of the water pump 8 is connected to the main pipe 9. The front and rear ports of the main pipe 9 are both closed. A plurality of cleaning pipes 11 are connected to the bottom surface of the main pipe 9 at intervals along its length direction. The spacing between each two adjacent cleaning pipes 11 is equal. The cleaning pipe 11 passes through the connecting plate 5 downward and extends directly above the net basket 4. A plurality of water outlet holes 12 are opened on the bottom surface of the extended end of the cleaning pipe 11, and the water outlet holes 12 are evenly distributed on the cleaning pipe 11. The main pipe 9 is arranged longitudinally, and a support plate 17 is welded on the outer wall of the extended end of the cleaning pipe 11. The support plate 17 is welded to the bottom surface of the connecting plate 5 to fix the cleaning pipe 11 to the connecting plate 5.
[0023] The method of the nitrogen and phosphorus concentration regulating device for regulating the concentration of nitrogen and phosphorus nutrient solution in farmland water is: S1. The farmer supports the support frame 13 of the nitrogen and phosphorus concentration regulating device on the soil layer of the planting area. At this time, the farmland water in the planting area sequentially passes through the liquid holes 2 of the rectangular shell 1 and the mesh holes of the net basket 4, and finally immerses the microbial particles; S2. Farmers put nitrogen and phosphorus fertilizers into farmland water, and farmland water dissolves nitrogen and phosphorus fertilizers into nitrogen and phosphorus nutrient solution, which promotes the growth of aquatic crops; When too much nitrogen and phosphorus fertilizers are applied, the concentration of the corresponding nitrogen and phosphorus nutrient solution also increases. At this time, the microbial particles absorb part of the nitrogen and phosphorus nutrient solution on them, thereby reducing the concentration of the nitrogen and phosphorus nutrient solution and making the concentration of the nitrogen and phosphorus nutrient solution reach a normal level; when the concentration of the nitrogen and phosphorus nutrient solution in the farmland water is lower than the normal level, the microbial particles will release the nitrogen and phosphorus nutrient solution adsorbed on them into the farmland water to make the concentration of the nitrogen and phosphorus nutrient solution reach a normal level again, thereby achieving the regulation of the concentration of the nitrogen and phosphorus nutrient solution in the farmland water, and then promoting the normal growth of aquatic crops.
[0024] After the nitrogen and phosphorus concentration regulating device has been used for a period of time, a large amount of sludge will also adhere to the microbial particles. At this time, the method for farmers to clean the microbial particles is: S3. The farmer rotates the handwheel 16 of the left vertical screw nut pair 6 with his left hand, and at the same time, rotates the handwheel 16 of the right vertical screw nut pair 6 with his right hand. The handwheel 16 drives the screw 14 to rotate, and the nut 15 moves upward along the screw 14. The nut 15 drives the rod 7 to move upward, and the rod 7 drives the lifting plate 3 to move upward. The lifting plate 3 drives the net basket 4 and the microbial particles in the net basket 4 to move upward synchronously. When the net basket 4 moves out of the rectangular shell 1, as shown in FIG. Fig.10 As shown, the farmer stops rotating the hand wheel 16, at which time, the microbial particles in the net basket 4 are no longer immersed in the farmland water, and at the same time, the microbial particles in the net basket 4 are just below the cleaning pipe 11; S4. The farmer turns on the water pump 8, and the water pump 8 pumps the clean water out of the clean water tank. Under the pump pressure, the clean water passes through the hose 10, the water pump 8, the main pipeline 9, the cleaning pipe 11 in sequence, and finally sprays downward from the water outlet 12 of the cleaning pipe 11. The spraying direction is as follows: Fig.11 As shown by the middle arrow, the sprayed clean water washes the microbial particles, and after a period of washing, the sludge attached to the microbial particles can be washed away; S5. After the microbial particles are cleaned, the farmer turns off the water pump 8, and then uses his left and right hands to rotate the handwheel 16 in opposite directions at the same time, and the nut 15 moves downward along the screw rod 14, and the nut 15 drives the rod 7 to move downward, and the rod 7 drives the lifting plate 3 to move downward, and the lifting plate 3 drives the net basket 4 to move downward, so that the net basket 4 re-enters the rectangular shell 1, and the cleaned microbial particles continue to work.
[0025] Among them, it can be seen from steps S3 to S5 that the farmer only needs to rotate the hand wheel 16 to lift the net basket 4 to the outside of the rectangular shell 1, and make the microbial particles contained in the net basket 4 enter the cleaning station of the cleaning pipe 11, so as to quickly clean the microbial particles; after cleaning, only need to rotate the hand wheel 16 in the opposite direction to put the net basket 4 back into the rectangular shell 1, so that the microbial particles continue to work. It can be seen that the nitrogen and phosphorus concentration regulating device of the farmland water is compared with the above Figure 1~Figure 4 The nitrogen and phosphorus concentration regulating device shown does not require farmers to carry the net basket 4 to the outer slope of the planting area to clean the microbial particles, nor does it require farmers to carry the net basket 4 from the outer slope to the location of the rectangular shell 1 to place the net basket 4 into the rectangular shell 1, thereby greatly saving the cleaning time of the microbial particles and greatly improving the cleaning efficiency of the microbial particles.
[0026] In addition, in step S4, the farmer only needs to turn on the water pump 8. Under the pump pressure, the clean water passes through the hose 10, the water pump 8, the main pipeline 9, the cleaning pipe 11 in sequence, and finally sprays downward from the water outlet 12 of the cleaning pipe 11. The sprayed clean water can wash the microbial particles. Figure 1~Figure 4 The nitrogen and phosphorus concentration regulating device shown does not require farmers to manually operate the nozzle to clean the microbial particles, but instead realizes automatic cleaning of the microbial particles, thereby greatly reducing the workload of cleaning the microbial particles.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
