Description

Technical Field

[0001] This utility model relates to the field of plant cultivation, and in particular to a tidal planting device with periodic water level changes. Background Technology

[0002] Tidal cultivation is an innovative cultivation technique that simulates ocean tides. It provides water and nutrients to plants by periodically raising and lowering the nutrient solution. When the tide rises, water comes into contact with the plant roots, and the plants absorb water and nutrients through capillary action. After the tide recedes, the nutrient solution is collected, filtered, disinfected, and recycled. It offers advantages such as water and fertilizer conservation, promotion of root development, and reduced labor costs. Current tidal cultivation methods utilize a siphon principle to further reduce energy consumption. This siphon principle pumps water from a storage tank to the plant culture dish, where it is then siphoned... The suction hood and drain pipe sequentially transport water back to the storage tank. However, during operation, the water pump works at a constant instantaneous flow rate. As the siphon process progresses, the liquid level difference between the plant culture dish and the storage tank gradually decreases, causing the instantaneous siphon flow rate to decrease synchronously. Consequently, at a certain moment, the two instantaneous flow rates may reach equilibrium, making it impossible to raise the water level and achieve the maximum discharge volume, thus failing to form a constant siphon effect rather than a tidal siphon effect with water level changes. Furthermore, the siphon cannot be stably disconnected, making it difficult to ensure that the plant roots can periodically emerge from the water surface to contact the air, resulting in poor planting results. Utility Model Content

[0003] The purpose of this invention is to provide a tidal planting device with periodically changing water levels. This invention can achieve tidal planting with reciprocating water level changes under a constant instantaneous flow rate of a water pump, thus improving the practicality and reliability of tidal planting.

[0004] The technical solution of this utility model is as follows: A tidal planting device with periodic water level changes includes a planting box, a water storage tank inside the planting box, a cultivation box above the water storage tank, a planting basket on the top of the cultivation box, and a siphon mechanism inside the cultivation box. The siphon mechanism includes an inlet pipe, a drain pipe, and a water storage cup disposed inside the cultivation box. The inlet pipe is connected to the inside of the water storage tank via a water pump. The cultivation box is equipped with a siphon cover that encloses the drain pipe. A siphon tube is disposed on the siphon cover. The siphon inlet end of the siphon tube is located inside the water storage cup and has a gap with the bottom of the water storage cup. The height of the inlet of the drain pipe is lower than the height of the outlet of the inlet pipe but higher than the height of the mouth of the water storage cup.

[0005] In the aforementioned tidal planting device with periodic water level changes, the siphon tube is L-shaped, with its top horizontal and its siphon outlet end connected to the top of the siphon hood.

[0006] In the aforementioned tidal planting device with periodic water level changes, the inner diameter of the drain pipe is larger than the inner diameter of the siphon pipe.

[0007] In the aforementioned tidal planting device with periodic water level changes, the siphon inlet of the siphon tube has an oblique opening structure.

[0008] In the aforementioned tidal planting device with periodic water level changes, the bottom of the planting basket is lower than the mouth of the water storage cup.

[0009] In the aforementioned tidal planting device with periodic water level changes, the cultivation box is equipped with a root-blocking fence that separates the siphon mechanism and the planting basket.

[0010] In the aforementioned tidal planting device with periodic water level changes, the top of the planting box is provided with a mounting plate that spans across the top of the cultivation box, and the mounting plate is provided with a cultivation port for connecting the planting basket; the mounting plate is provided with symmetrically arranged mounting sockets, and the mounting sockets are provided with climbing trellises located above the cultivation ports.

[0011] In the aforementioned tidal planting device with periodic water level changes, the climbing frame includes multiple longitudinally connected C-shaped supports. The top two sides of the C-shaped supports are provided with connection ports, and the bottom of the C-shaped supports is inserted into the mounting socket or connection port.

[0012] Compared with existing technologies, this invention involves placing plants in planting baskets before use. A constant instantaneous flow of nutrient solution is pumped from a water tank into an empty incubator via a water pump and inlet pipe. As the liquid level rises to a high level, the nutrient solution enters a siphon hood through a siphon pipe. The liquid level in the siphon hood simultaneously reaches a high level until the nutrient solution begins to drain from the drain pipe into the water tank. The liquid level difference initiates the siphon, at which point the liquid level difference is at its maximum, and the instantaneous flow rate of the siphon is at its maximum and greater than the constant instantaneous flow rate of the water pump, causing the water level in the incubator to drop. When the water level drops to the mouth of the storage cup, there is still a liquid level difference sufficient to generate a sufficient instantaneous flow rate for the siphon. At this point, the siphon principle quickly removes the remaining nutrient solution in the storage cup and draws in air. Due to the limitation of the constant flow rate of the water pump, liquid outside the storage cup cannot be replenished in time, and the siphon stops. Subsequently, it is necessary to wait for the liquid level to rise to a high level again so that the nutrient solution can be drained from the drain pipe again, and the siphon restarts. This process is repeated, achieving cyclical changes in the water level in the incubator without needing to control the instantaneous flow rate of the water pump. Therefore, this invention raises the lowest water level in the incubator by using a water storage cup to create a sufficient liquid level difference to generate a siphon instantaneous flow rate greater than that of a water pump. It is highly convenient to use and balances the contact time between plant roots and nutrient solution and oxygen. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example: A tidal planting device with periodically changing water levels, as shown in the attached document. Figure 1 As shown, the system includes a planting box 1, inside which is a water storage tank 2. The bottom of the water storage tank has a drain for draining and replacing the nutrient solution. A cultivation box 3 is placed directly on top of the water storage tank 2. A planting basket 4 is fitted on top of the cultivation box 3. A siphon mechanism 5 is installed inside the cultivation box 3. Figure 2 and attached Figure 3As shown, the siphon mechanism 5 includes an inlet pipe 6, a drain pipe 7, and a water storage cup 8 fixed inside the incubator 3. The inlet pipe 6 is connected to the inside of the water storage tank 2 via a water pump. A siphon cover 9, which encloses the drain pipe 7, is fixed inside the incubator 3. A siphon tube 10 is integrally formed on the siphon cover 9. The siphon inlet end of the siphon tube 10 is located inside the water storage cup 8 and has a gap with the bottom of the water storage cup 8. The height of the inlet of the drain pipe 7 is lower than the height of the outlet of the inlet pipe 6 but higher than the height of the mouth of the water storage cup 8. The height of the inlet of the drain pipe is the highest water level in the incubator, and the height of the mouth of the water storage cup is the lowest water level in the incubator. The siphon tube 10 is L-shaped. The top of the siphon tube 10 is horizontal, and its siphon outlet is connected to the top of the siphon cover 9, ensuring stable and smooth flow of nutrient solution within the siphon tube. The inner diameter of the drain pipe 7 is larger than that of the siphon tube 10 to avoid bottlenecks and ensure rapid formation of the siphon principle and stable instantaneous flow. The siphon inlet of the siphon tube 10 is machined into an oblique structure, providing a larger inlet area, and the resulting height difference facilitates air communication, making it more sensitive to changes in water level in the storage cup and enabling rapid termination of the siphon and timely raising of the water level. The bottom of the planting basket 4 is lower than the mouth of the storage cup 8, ensuring that the plant roots are always partially in contact with the nutrient solution. The culture box 3 uses a suction... The siphon mechanism 5 and the planting basket 4 are fixed by a plate adsorption method, which prevents the plant roots from entering the siphon structure and causing blockage. A mounting plate 12 is fixed to the top of the planting box 1, spanning above the culture box 3. The mounting plate 12 is equipped with a culture port 13 for connecting the planting basket 4. Symmetrically arranged mounting slots 14 are opened on the mounting plate 12, and a climbing frame 15 is fixed to each mounting slot 14 above the culture port 13, suitable for climbing plants and expanding its applicability. The climbing frame 15 includes multiple longitudinally connected C-shaped supports 16. Connection ports 17 are opened on both sides of the top of the C-shaped supports 16, and the bottom of the C-shaped supports 16 connects to... The installation port 14 or connector 17 can be plugged in to flexibly set the number of C-shaped supports to adjust the height of the climbing frame, which is suitable for climbing plants of various lengths. An IoT remote control box is installed on the side wall of the planting box. The cultivation box is equipped with a nutrient solution EC value sensor, liquid level sensor and temperature sensor connected to the control box. After receiving the sensor signals, they are transmitted through a wireless network. This is a technical means that is well known and mastered by those skilled in the art, and will not be described in detail here. The top of the planting box is equipped with a hinged cover that opens and closes in opposite directions. The cover has a slot that is compatible with the planting basket and the bottom C-shaped support. When the cover is closed, it can seal the top of the planting box, thereby reducing the entry of impurities.

[0021] Working principle: After the water pump 18 starts, the nutrient solution in the water storage tank 2 is injected into the incubator 3 at a constant flow rate through the inlet pipe 6. As the liquid level gradually rises, the nutrient solution enters the water storage cup 8 through the inlet end of the siphon pipe 10, gradually filling the water storage cup 8; as shown in the attached... Figure 4As shown, when the liquid level rises to the height of the inlet of the drain pipe 7 (the highest water level in the incubator 3), the liquid level inside the siphon hood 9 simultaneously reaches a high level. At this time, the siphon effect is triggered, and the nutrient solution begins to flow rapidly into the siphon hood 9 through the siphon pipe 10 and is discharged back into the storage tank 2 through the drain pipe 7. Since the height of the inlet of the drain pipe 7 is lower than the height of the outlet of the inlet pipe 6, the liquid level difference is the largest in the initial stage, and the instantaneous flow rate generated by the siphon significantly exceeds the constant flow rate of the water pump. At this time, the liquid level in the incubator 3 drops rapidly, and the nutrient solution flows back to the storage tank 2 in large quantities through the drain pipe 7. Figure 5 As shown, during this process, the height of the rim of the water storage cup 8 (the lowest water level in the incubator 3) ensures that a certain amount of nutrient solution is retained even when the liquid level drops, preventing the plant roots from completely detaching from the liquid environment. When the liquid level drops to the rim of the water storage cup 8, the remaining nutrient solution in the water storage cup 8 is quickly drawn in by the siphon tube 10. Air enters through the gap between the inlet of the siphon tube 10 and the bottom of the water storage cup 8, causing the siphon effect to be interrupted. At this time, the water pump continues to inject nutrient solution into the incubator 3, but because the siphon stops, the liquid level begins to rise again. When the liquid level reaches the height of the inlet of the drain pipe 7 again, the siphon effect is retried, and the next cycle begins. Through the above cycle, this invention achieves the periodic rise and fall of the water level in the incubator 3 without adjusting the instantaneous flow rate of the water pump, simulating the natural tidal environment, optimizing the balance of water, nutrients and oxygen absorption by the plant roots, and significantly improving planting efficiency and convenience.
