Description

Technical Field

[0001] This utility model relates to the field of cultivation device technology, specifically a solar-powered aeroponic device suitable for vegetable cultivation. Background Technology

[0002] Aeroponics, or aeroponics for short, is a novel soilless cultivation method that uses atomized nutrient solution to meet the water and fertilizer needs of plant roots. Its basic principle is to suspend the plant roots in a closed, light-blocked environment. The nutrient solution is sprayed intermittently onto the plant roots through special equipment under the control of an automatic system, providing the water and nutrients needed for plant growth. A search revealed Chinese patent publication number CN220823796U, which discloses an aeroponics spray water supply device for vegetable cultivation: a water supply device, an irrigation device, and a motor; a guide channel is provided on the cover between the cultivation holes; the bottom of the guide channel has several holes that communicate with the interior of the container; a water supply device is located at one corner of the container; the bottom of the water supply device is connected to the container, and its head is positioned above the cover.

[0003] While the above-mentioned technical solution can irrigate the roots of vegetables and replenish water at the top, with excess water flowing back into the box through the holes for reuse, greatly improving utilization, the irrigation device only has a single set of spray nozzles in the center of the box. Due to the attenuation of the atomization distance, it cannot spray the vegetable roots comprehensively. Furthermore, the box cover uses a simple hinged structure, which can only open and close, and cannot adjust the spacing according to the growth height of the vegetables, which can restrict vegetable growth and is difficult to adapt to the different growth stages and the requirements of the nozzle distance.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example:

[0021] like Figures 1 to 3 As shown, a solar-powered aeroponic device suitable for vegetable cultivation includes a base 1, a support 2 fixedly connected to the upper surface of the base 1, a bottom frame 3 fixedly connected to the top of the support 2, the bottom of the bottom frame 3 being semi-circular, a top frame 4 slidably connected inside the bottom frame 3, a cover plate 5 installed on the top of the top frame 4, and multiple vegetable cultivation holes 6 sequentially opened on the top of the cover plate 5. A hydraulic cylinder 7 is fixedly installed on one side of the upper surface of the base 1, and the movable end of the hydraulic cylinder 7 is fixedly connected to one side of the top frame 4.

[0022] When in use, the operation of hydraulic cylinder 7 can drive the top frame 4 to rise and fall, thereby making it easy to adjust the height of the device according to the condition of the vegetable roots, and avoiding bending of the vegetable roots to affect nutrient absorption.

[0023] like Figures 1 to 4As shown, a first atomizing mechanism is installed through the interior of the base frame 3. The first atomizing mechanism includes a first connecting pipe 8 that is symmetrically and rotatably connected to both sides of the interior of the base frame 3. Multiple first atomizing nozzles 9 are sequentially fixedly installed on the outer surface of the first connecting pipe 8.

[0024] The rotation of the first connecting pipes 8 on both sides drives the first atomizing nozzle 9 to rotate, which can evenly atomize and spray nutrient solution onto the roots of vegetables, allowing the roots to fully absorb the nutrient solution.

[0025] A second atomizing mechanism is installed on one side of the upper surface of the base 1. The second atomizing mechanism includes a support cylinder 10 fixedly installed on the upper surface of the base 1. A support rod 11 is slidably connected inside the support cylinder 10. A locking bolt for fixing the support rod 11 is threaded through one side of the support cylinder 10. A support frame 12 is fixedly connected to the top of the support rod 11. A bidirectional screw is rotatably connected through the inside of the support frame 12. Two mounting blocks 13 are symmetrically threaded on the outer surface of the bidirectional screw. A second connecting pipe 14 is rotatably connected through the outer surface of the mounting blocks 13. Multiple second atomizing nozzles 15 are sequentially fixedly installed on the outer surface of the second connecting pipe 14.

[0026] The rotation of the two second connecting pipes 14 can drive the rotation of the second atomizing nozzle 15, which can spray nutrient solution onto the vegetable leaves. Before spraying, the height of the support rod 11 can be adjusted to change the height of the second atomizing nozzle 15, which is convenient to adapt to vegetables of different heights. The rotation of the bidirectional screw can drive the two second connecting pipes 14 and the second atomizing nozzle 15 on both sides to move relative to each other, which is convenient to adapt to vegetables of different diameters.

[0027] It should be noted that a rotary joint 16 is installed at one end of both the first connecting pipe 8 and the second connecting pipe 14. The rotary joint 16 allows for normal liquid supply when the first connecting pipe 8 and the second connecting pipe 14 are rotated.

[0028] Both the first connecting pipe 8 and the second connecting pipe 14 are driven by an external motor. The external motor facilitates the rotation of the first connecting pipe 8 and the second connecting pipe 14. In this technical solution, gears can be installed on the outer surfaces of the first connecting pipe 8 and the second connecting pipe 14, and then the external motors can be installed at corresponding positions on the outer surfaces of the bottom frame 3 and the mounting block 13. The output shaft of the external motor is also equipped with gears. Therefore, the rotation of the external motor can drive the corresponding first connecting pipe 8 and the second connecting pipe 14 to rotate. This is a driving method commonly used by those skilled in the art and belongs to the prior art.

[0029] The upper surface of the base 1 is equipped with a drive mechanism that cooperates with the first aeroponic mechanism and the second aeroponic mechanism. The drive mechanism includes a liquid storage tank 17 and a water pump 18 fixedly installed on the base 1. The water outlet of the water pump 18 is connected to the corresponding rotary joint 16 through a pipe.

[0030] The operation of the water pump 18 can transport the nutrient solution in the storage tank 17 to the corresponding first connecting pipe 8 and second connecting pipe 14, and then spray it out through the corresponding first atomizing nozzle 9 or second atomizing nozzle 15.

[0031] A mounting bracket 19 and a power cabinet 20 are installed on the base 1. A solar panel 21 connected to the power cabinet 20 is installed on the top of the mounting bracket 19.

[0032] The solar panel 21 can generate electricity using solar energy, and then the energy is collected by the power cabinet 20 to power the water pump. This is a common technical method used by those skilled in the art.

[0033] A first return water pipe 22 is connected between one side of the bottom frame 3 and the storage tank 17. A baffle 23 is fixedly connected to the upper surface of the cover plate 5. Two collection tanks 24 are symmetrically opened on the upper surface of the cover plate 5. A second return water pipe 25 is connected between the collection tanks 24 and the storage tank 17. Excess nutrient solution can be recycled.

[0034] Working principle: The solar power panel 21 collects and stores the electrical energy converted from solar energy through the power cabinet 20, which powers the water pump 18 and external motor, etc. When the water pump 18 is running, it delivers the nutrient solution in the storage tank 17 to the first connecting pipe 8 and the second connecting pipe 14 through the pipe and the rotary joint 16. The external motor drives the two connecting pipes to rotate, which drives the first atomizing nozzle 9 to spray the vegetable roots and the second atomizing nozzle 15 to spray the vegetable leaves evenly. The hydraulic cylinder 7 can drive the top frame 4 to rise and fall to adapt to the growth of the vegetable roots. The support rod 11 can be adjusted in height by locking bolts. The bidirectional screw can drive the mounting block 13 and the second connecting pipe 14 to move, thereby adapting to vegetables of different heights and diameters. Excess nutrient solution flows back to the storage tank 17 through the first return water pipe 22 on one side of the bottom frame 3 and the collection groove 24 on the cover plate 5 in conjunction with the second return water pipe 25 to achieve recycling.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
