Description

Technical Field

[0001] This utility model relates to the field of algae cultivation technology, specifically an algae cultivation nutrient solution dispensing device. Background Technology

[0002] Algae cultivation refers to the process of cultivating and propagating algae (such as microalgae and macroalgae) in an artificially controlled environment. It is widely used in food, medicine, bioenergy, environmental remediation, and many other fields. Algae growth requires sufficient nutrients, necessitating the addition of nutrient solutions to supplement key elements such as nitrogen, phosphorus, and potassium, as well as trace elements, to promote photosynthesis and metabolism, thereby increasing yield and quality.

[0003] Currently, the main methods for adding nutrient solutions in algae cultivation include manual sprinkling and fixed-pipe drip irrigation. Manual sprinkling relies on manual operation, which is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniform distribution of nutrient solutions in the aquaculture water. While fixed-pipe drip irrigation can achieve a certain degree of automation, the fixed pipe positions mean that it can only be applied to specific areas. For scenarios such as large circular aquaculture ponds, it cannot cover the entire aquaculture area, which can easily lead to uneven algae growth. Furthermore, it has shortcomings in adjusting the application depth, as it cannot accurately adjust the application depth according to the algae growth stage (such as the distribution of algae at different depths), resulting in the nutrient solution being concentrated on the surface or deep layers, leading to low utilization. Utility Model Content

[0004] The purpose of this invention is to provide a device for dispensing nutrient solution for algae cultivation, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] Please see Figures 1-5 In this embodiment of the invention, an algae cultivation nutrient solution dispensing device includes:

[0037] A circular aquaculture pond 1 has an annular groove 3 on its top surface and an axial flow submersible pump installed at the bottom of the circular aquaculture pond 1.

[0038] The isolation column 2 is fixedly installed at the center of the circular aquaculture pond 1 to form a ring track. The top surface of the circular aquaculture pond 1 is provided with an installation groove 28.

[0039] And the agencies that distribute the products, including:

[0040] The drive mechanism 7 is fixedly installed on the isolation column 2 via the mounting slot 28;

[0041] The mounting strip 5 is fixedly connected to the drive mechanism 7. A support component 6 is provided between the end of the mounting strip 5 away from the drive mechanism 7 and the annular groove 3. A through groove 18 is provided on the top surface of the mounting strip 5.

[0042] A lifting mechanism 8 that is slidably mounted on the mounting plate 5;

[0043] The delivery mechanism 9 is installed at the bottom of the lifting mechanism 8;

[0044] And a liquid supply mechanism 4 fixedly installed on the drive mechanism 7, the liquid supply mechanism 4 being used to supply nutrient solution to the dispensing mechanism 9.

[0045] An axial flow submersible pump causes the water in the circular aquaculture pond 1 to flow along the annular track, forming a circulating water flow; the drive mechanism 7 drives the mounting plate 5 to rotate around the isolation column 2, enabling the dispensing mechanism 9 to move within the annular aquaculture area; the liquid supply mechanism 4 delivers nutrient solution to the dispensing mechanism 9, which then dispenses the nutrient solution into the water; the lifting mechanism 8 can adjust the depth of the dispensing mechanism 9 to adapt to different dispensing needs.

[0046] By driving the dispensing mechanism to rotate, the nutrient solution is dynamically dispensed within the circular aquaculture area, which can more evenly cover the entire aquaculture pond compared to dispensing at a fixed location.

[0047] The lifting mechanism allows for flexible adjustment of the dispensing depth, improving the contact efficiency between the nutrient solution and algae.

[0048] Example 2:

[0049] Please see Figures 1-3 and Figure 5 Based on embodiment 1, the drive mechanism 7 includes a motor 10 fixedly installed in the mounting groove 28. The output shaft of the motor 10 extends to the top of the isolation column 2 and is fixedly installed with a coaxially arranged turntable 29. A liquid supply mechanism 4 is fixedly installed on the top surface of the turntable 29, and a mounting strip 5 is fixedly connected to the periphery of the turntable 29.

[0050] A thrust bearing 11 is provided between the bottom surface of the turntable 29 and the top surface of the isolation column 2.

[0051] After the motor 10 starts, its output shaft drives the turntable 29 to rotate, and the turntable 29 in turn drives the mounting plate 5 and the liquid supply mechanism 4 to rotate synchronously; the thrust bearing 11 plays a supporting role between the turntable 29 and the isolation column 2, reducing the frictional resistance when the turntable rotates.

[0052] Among them, the motor drive enables the automated rotation of the dispensing mechanism without manual intervention, thus improving dispensing efficiency; the thrust bearing reduces frictional loss during turntable rotation, extends the service life of the equipment, and ensures the smoothness of the rotation process.

[0053] Example 3:

[0054] Please see Figures 1-3 Based on embodiment 2, the lifting mechanism 8 includes bolts 24 and a limiting plate 21 set above the mounting strip 5. A lifting rod 20 is fixedly connected to the middle position of the bottom surface of the limiting plate 21, and limiting rods 19 are fixedly connected to both ends. The bottom ends of the lifting rod 20 and the limiting rods 19 slide through the mounting strip 5 to the bottom of the mounting strip 5. A mounting plate 25 for mounting the delivery mechanism 9 is fixedly connected between the bottom end of the lifting rod 20 and the bottom ends of the two limiting rods 19.

[0055] The lifting rod 20 has an abutment groove 23 on its outer periphery and is also provided with a scale 22;

[0056] Bolt 24 is threaded through and installed on the side of mounting plate 5 near the contact groove 23, with the front end of bolt 24 extending into the contact groove 23.

[0057] When adjusting the dispensing depth, loosen bolt 24, and the lifting rod 20 and the limiting rod 19 will slide up and down through the limiting plate 21. The height of the mounting plate 25 and the dispensing mechanism 9 can be precisely controlled according to the scale 22 on the lifting rod 20. After the adjustment is completed, tighten bolt 24 so that the front end of the bolt is pressed into contact with the abutment groove 23 to fix the position of the lifting rod 20.

[0058] In this embodiment, the depth of the dispensing mechanism can be precisely adjusted by the scale, allowing for targeted dispensing based on the distribution depth of algae at different growth stages, thereby improving the utilization rate of the nutrient solution.

[0059] The limit bar ensures the stability of the lifting process and prevents the dispensing mechanism from shaking.

[0060] The fit between the bolts and the contact groove securely fixes the lifting position, ensuring a stable and reliable delivery process.

[0061] Example 4:

[0062] Please see Figure 2 Based on embodiment 3, the dispensing mechanism 9 includes a dispensing pipe 26 fixedly installed on the bottom surface of the mounting plate 25. Multiple arrayed diversion pipes 27 are fixedly installed through the periphery of the dispensing pipe 26. A flexible telescopic conduit 17 is fixedly connected through the end of the dispensing pipe 26 near the isolation column 2. The end of the flexible telescopic conduit 17 away from the dispensing pipe 26 passes through the through groove 18 and is connected to the liquid outlet end of the liquid supply mechanism 4.

[0063] The nutrient solution delivered by the supply mechanism 4 enters the delivery pipe 26 through the flexible telescopic conduit 17, and is then evenly discharged into the aquaculture water body through multiple arrayed diversion pipes 27; the flexible telescopic conduit 17 can extend and retract with the movement of the lifting mechanism 8, without affecting the adjustment of the delivery depth.

[0064] The installation of multiple branch pipes allows nutrient solution to be dispensed simultaneously from multiple points, improving the uniformity of nutrient solution distribution in local areas.

[0065] Example 5:

[0066] Please see Figure 2 Based on embodiment 4, the liquid supply mechanism 4 includes a liquid storage tank 15 fixedly installed on the top surface of the turntable 29, and a liquid pump 16 fixedly installed on the top surface of the mounting plate 5. The liquid inlet end of the liquid pump 16 extends into the liquid storage tank 15, and the liquid outlet end of the liquid pump 16 is fixedly connected to the end of the flexible telescopic conduit 17 away from the delivery pipe 26.

[0067] After the liquid pump 16 is started, the nutrient solution in the storage tank 15 is extracted and transported to the dispensing mechanism 9 through the flexible telescopic conduit 17. By controlling the running speed of the liquid pump 16, the amount and speed of nutrient solution dispensing can be adjusted to meet the nutritional needs of algae at different growth stages and avoid waste or insufficiency of nutrient solution.

[0068] Example 6:

[0069] Please see Figures 1-4Based on embodiment 1, the support assembly 6 includes a sliding column 13 slidably installed in the annular groove 3. The bottom surface of the sliding column 13 is embedded with a ball bearing 14 that rolls in contact with the bottom surface of the annular groove 3. A support column 12 is fixedly installed on the top surface of the sliding column 13. The top end of the support column 12 is rotatably connected to the bottom surface of the mounting strip 5.

[0070] When the mounting plate 5 rotates, the support column 12 drives the sliding column 13 to slide in the annular groove 3. The ball bearings 14 on the bottom surface of the sliding column 13 roll in contact with the bottom surface of the annular groove 3, reducing sliding friction. The top of the support column 12 is rotatably connected to the bottom surface of the mounting plate 5, so that the sliding column 13 can rotate with the annular groove 3, further reducing friction.

[0071] The support component 6 provided in this embodiment effectively supports the end of the mounting strip 5 away from the drive mechanism, enhancing the stability of the overall structure and preventing the mounting strip 5 from bending and deforming due to one end being suspended.

[0072] The ball bearing 14 significantly reduces the frictional resistance between the slide column 13 and the annular groove 3, making the mounting plate 5 rotate more smoothly and reducing energy consumption and component wear.

[0073] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
