[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 2 , an embodiment provided by the present utility model: A tidal cultivation device includes a cultivation rack 1, a cultivation tank 2 is fixedly connected inside the cultivation rack 1, a cultivation trough cover 3 is fixedly connected inside the cultivation tank 2. When a plant is placed above the cultivation trough cover 3, the root system of the plant can enter the cultivation tank 2 for tidal cultivation. A partition board 4 is arranged inside the cultivation tank 2, and the partition board 4 can divide the internal space of the cultivation tank 2. A moving unit is arranged outside the partition board 4. The moving unit includes a lead screw 41. The lead screw 41 is rotatably connected to the inner bottom surface of the cultivation tank 2. The upper end of the lead screw 41 penetrates through the partition board 4 and the cultivation trough cover 3. The thread on the outside of the lead screw 41 is an internal thread, and the lead screw 41 is threadedly connected to the partition board 4. When the lead screw 41 rotates, it can drive the partition board 4 to move synchronously. The lead screw 41 is inserted into the cultivation trough cover 3 to prevent the cultivation trough cover 3 from hindering the rotation of the lead screw 41. The upper end of the lead screw 41 is fixedly connected with a handle 42, and the user can drive the lead screw 41 to rotate through the handle 42. The left and right ends of the bottom surface of the partition board 4 are fixedly connected with telescopic rods 43, and the bottom ends of the telescopic rods 43 are fixedly connected to the inner bottom surface of the cultivation tank 2. The arranged telescopic rods 43 can guide and limit the movement of the partition board 4, so that the partition board 4 can only move in a straight line in the up and down direction. When the user rotates the handle 42, the partition board 4 can be driven to move in a straight line in the up and down direction under the cooperation of the lead screw 41 and the telescopic rods 43. When the partition board 4 moves in a straight line up and down inside the cultivation tank 2, the internal space of the cultivation tank 2 can be changed.

[0033] Refer toFigure 2 - Figure 3 , an annular groove 5 is formed on the outer wall surface of the partition plate 4, and an annular airbag 6 is fixedly connected to the inner top surface of the annular groove 5. When the annular airbag 6 expands, it can seal the gap between the partition plate 4 and the inner wall of the cultivation tank 2. After the user adjusts the position of the partition plate 4 according to the root length of the plant, air can be inflated into the annular airbag 6 to make the annular airbag 6 expand and seal the gap between the partition plate 4 and the inner wall of the cultivation tank 2, avoiding water leakage from the gap. At this time, the size of the space above the partition plate 4 is adapted to the root length of the plant, which can reduce the usage amount of the culture solution during cultivation and avoid filling the inside of the cultivation tank 2 every time for cultivation, resulting in waste of some culture solution.

[0034] An air pump 7 is arranged at the rear side of the cultivation rack 1, and an inflation unit is arranged on the outer side of the annular airbag 6. The inflation unit includes a telescopic hose 61, the telescopic hose 61 is fixedly connected to the bottom surface of the annular airbag 6, the bottom end of the telescopic hose 61 penetrates through the partition plate 4, the bottom end of the telescopic hose 61 is fixedly connected with a side air pipe 62, and the end of the side air pipe 62 far away from the telescopic hose 61 penetrates through the cultivation tank 2. The side air pipe 62 is fixedly connected with the cultivation tank 2. When the partition plate 4 moves in a straight line up and down, it can drive the telescopic hose 61 to expand and contract synchronously, avoiding hindering the movement of the partition plate 4. The end of the side air pipe 62 far away from the telescopic hose 61 is fixedly connected with a main air pipe 63. The inside of the main air pipe 63 is communicated with the inside of the annular airbag 6 through the side air pipe 62 and the telescopic hose 61. The bottom end of the main air pipe 63 is fixedly connected with the front output end of the air pump 7. When it is necessary to seal the gap between the partition plate 4 and the inner wall of the cultivation tank 2, the air pump 7 can be started to inflate the annular airbag 6 to make the annular airbag 6 expand and seal.

[0035] Refer to Figure 3 and Figure 5, this practical case also provides a tidal liquid discharger for a tidal cultivation device, including a nutrient solution pool 8, which is arranged on the front side of the cultivation rack 1. A liquid return pipe 9 is fixedly connected to the right side surface of the nutrient solution pool 8. An electromagnetic valve is fixedly connected to the outer side of the liquid return pipe 9. One end of the liquid return pipe 9 away from the nutrient solution pool 8 penetrates through the cultivation rack 1 and is fixedly connected to the bottom surface of the cultivation tank 2. The used culture solution in the cultivation tank 2 can return to the nutrient solution pool 8 through the liquid return pipe 9. An overflow pipe 10 is fixedly connected to the back surface of the nutrient solution pool 8. One end of the overflow pipe 10 away from the nutrient solution pool 8 is fixedly connected to the upper side of the front side surface of the cultivation tank 2. As the nutrient solution continuously enters the cultivation tank 2, the liquid level will continuously rise. A liquid inlet pipe 11 is fixedly connected to the left side surface of the nutrient solution pool 8. One end of the liquid inlet pipe 11 away from the nutrient solution pool 8 penetrates through the cultivation rack 1 and the cultivation tank cover 3. A water pump is fixedly connected to the outer side of the liquid inlet pipe 11. A filter box 12 is fixedly connected to the inside of the liquid inlet pipe 11. A filtering unit is arranged inside the filter box 12, and the filtering unit can filter the nutrient solution passing through the inside of the filter box 12.

[0036] Turn on the water pump, send the nutrient solution and water in the nutrient solution pool 8 into the liquid inlet pipe 11 through the water pump, filter out the impurities through the filtering unit, and introduce them into the cultivation tank 2. As time goes by, the liquid level in the cultivation tank 2 rises to the overflow pipe 10. During this process, the plants will continuously absorb water or nutrient solution until they are saturated. When water overflows in the cultivation tank 2, the water pump can be turned off. After the plants absorb until they are saturated, start the air pump 7 to pump air into the annular airbag 6, and open the gap between the partition plate 4 and the cultivation tank 2, so that the liquid above the partition plate 4 at this time can flow to the inner bottom end of the cultivation tank 2. At this time, open the electromagnetic valve, and the liquid in the cultivation tank 2 will flow back to the nutrient solution pool 8 through the liquid return pipe 9. After the plants finish absorbing, stop the water supply until the next liquid supply.

[0037] Refer to Figure 6, the filtering unit includes a filter plate 121. The filter plate 121 is arranged inside the filtering box 12. The filter plate 121 can filter the nutrient solution entering the inside of the filtering box 12 to avoid blockage inside the cultivation device and the liquid discharge device caused by the liquid. A collection box 122 is fixedly connected to the front surface of the filter plate 121. The outer walls of the filter plate 121 and the collection box 122 are both in close contact with the inner wall of the filtering box 12. The collection box 122 can completely collect the impurities entering the inside of the filtering box 12. A counterweight 123 is fixedly connected to the bottom surface of the collection box 122. The counterweight 123 can enhance the stability of the filtering unit. A baffle 124 is fixedly connected to the top end of the filter plate 121. The baffle 124 penetrates through the filtering box 12 and is inserted between the baffle 124 and the inner wall of the filtering box 12. When the baffle 124 moves upward, it can drive the filter plate 121 and the collection box 122 out of the filtering box 12 for cleaning, which is quick and simple, and can avoid the situation where impurities still accumulate inside the filtering box 12 after the filter plate 121 is disassembled. A handle 125 is fixedly connected to the upper surface of the baffle 124. The staff can drive the baffle 124 to move through the handle 125, which is convenient for operation. A support rod 126 is fixedly connected to the bottom surface of the baffle 124. The bottom end of the baffle 124 is fixedly connected to the inner bottom surface of the collection box 122. The support rod 126 can limit and support the baffle 124 to avoid the baffle 124 being bent and stuck in the collection box 122 and unable to move.

[0038] Working principle: When hydroponically cultivating plants, the user can rotate the grip 42 according to the length of the plant rhizome to drive the partition plate 4 to move up and down to adjust the space above the partition plate 4, so that the amount of nutrient solution entering the inside of the cultivation tank 2 can be adapted to the length of the plant rhizome, reducing waste. After the adjustment is completed, the air pump 7 can be started to inflate the annular airbag 6 through the inflation unit, so that the annular airbag 6 expands to seal the gap between the partition plate 4 and the inner wall of the cultivation tank 2. Subsequently, the water pump can be started to pump the nutrient solution through the liquid inlet pipe 11 into the cultivation tank 2, and the filtering unit can filter the nutrient solution entering the inside of the cultivation tank 2, so that the plants can absorb water and the required nutrients. When the water overflows in the cultivation tank 2, the water pump is turned off. After waiting for the plants to absorb completely, the air pump 7 is started to pump air into the annular airbag 6, and the gap between the partition plate 4 and the cultivation tank 2 is opened, so that the liquid above the partition plate 4 at this time can flow to the inner bottom end of the cultivation tank 2. Then, the solenoid valve is opened, and the liquid in the cultivation tank 2 will flow back to the nutrient solution pool 8 through the liquid return pipe 9, and then wait for the next liquid supply.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
