Description

Technical Field

[0001] This utility model belongs to the field of hydroponic technology, specifically a hydroponic device with controllable water depth. Background Technology

[0002] Hydroponics is a soilless cultivation technique that promotes plant growth and development by providing nutrients in water. Compared to traditional soil cultivation, hydroponics offers higher space utilization and production efficiency. Common hydroponic systems include deep-water culture, nutrient film technology, and aeroponics. Hydroponics not only reduces pests and diseases but also effectively conserves water resources, making it suitable for urban agriculture and indoor planting. Due to its high controllability, hydroponics allows for year-round production without seasonal limitations and is widely used in the cultivation of vegetables, fruits, and flowers. Traditional hydroponic systems have a planting board fixed to the top of the nutrient solution tank. During hydroponics, the liquid inside the tank is absorbed by the plants and evaporates, causing the tank to become submerged and lower. This exposes the plant roots to air, affecting plant growth. Therefore, manual replenishment of liquid is necessary to ensure the plant roots are submerged. This type of hydroponic system has inherent limitations and requires improvement.

[0005] 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. Figures 1 to 3The present invention includes a liquid storage tank 1 and a planting plate 2. The planting plate 2 is located inside the liquid storage tank 1 and can be raised and lowered. Planting holes 3 for planting plants are opened at equal intervals on the surface of the planting plate 2. Connecting plates 4 are fixedly installed at both ends of the planting plate 2. Sleeves 5 are fixedly installed in the middle of one side of each of the two connecting plates 4. Rotating columns 6 located inside the two sleeves 5 are rotatably installed at both ends of the bottom of the liquid storage tank 1. A dual-shaft motor 7 for adjusting the rotating columns 6 is installed at the bottom of the liquid storage tank 1. Threaded grooves 8 are opened on the surface of each of the two rotating columns 6. A lever pin 9 located inside the threaded groove 8 is fixedly installed inside each of the two sleeves 5. The bottoms of both rotating columns 6 extend to the bottom of the liquid storage tank 1 and are fixedly installed with bevel gears A10. The two output ends of the dual-output shaft motor 7 are connected to adjusting shafts 11. The ends of the two adjusting shafts 11 away from the dual-output shaft motor 7 are fixedly installed with bevel gears B12 that mesh with bevel gears A10, thus enabling effective adjustment. The starting of the dual-output shaft motor 7 drives the two adjusting shafts 11 to rotate. The rotation of the two adjusting shafts 11 drives the two bevel gears B12 to rotate, which in turn drives the two bevel gears A10 to rotate. The rotation of the two bevel gears A10 drives the two rotating columns 6 to rotate. The rotation of the two rotating columns 6 drives the actuating pins 9 to move downward through the threaded grooves 8 on their surfaces. The downward movement of the actuating pins 9 drives the sleeves 5 to move downward on the surface of the rotating columns 6. The downward movement of the two sleeves 5 drives the planting plate 2 to move downward inside the liquid storage tank 1 through the two connecting plates 4, so that the plant roots on the planting plate 2 can always be submerged in the liquid inside the liquid storage tank 1. A maximum water level sensor A13 and a minimum water level sensor B14 are installed on the upper and lower parts of one end of the liquid storage tank 1. A microcontroller 15 is installed in the middle of one end of the liquid storage tank 1. Water level sensors 16 are installed at both ends of the bottom of the planting plate 2. The dual-output shaft motor 7, the maximum water level sensor A13, the minimum water level sensor B14, and the water level sensor 16 are all connected to the microcontroller 15 via wires, thereby enabling effective automatic control. When the water level sensor 16 at the bottom of the planting plate 2 does not detect liquid, the water level sensor 16 will send an electrical signal to the microcontroller 15. At this time, the microcontroller 15 controls the dual output shaft. Motor 7 rotates several times; simultaneously, the highest water level sensor A13 and the lowest water level sensor B14 maintain a reliable water depth in the storage tank 1; when the highest water level sensor A13 detects water, it sends an electrical signal to the microcontroller 15, causing the microcontroller 15 to stop the external water pump from adding liquid to the storage tank 1; and when the lowest water level sensor B14 does not detect water, it sends an electrical signal to the microcontroller 15, causing the microcontroller 15 to turn on the external water pump to add liquid to the storage tank 1, while simultaneously controlling the dual-output shaft motor 7 to rotate in the opposite direction, thereby controlling the adjusting planting plate 2 to move up to the highest position inside the storage tank 1.Both connecting plates 4 have rectangular inner grooves 17 in the middle. Square baffles 18 are fixedly installed inside the rectangular inner grooves 17 at both ends of the bottom of the liquid storage tank 1, so that the planting plate 2 can move upward stably and effectively prevent plant roots from getting tangled on the surface of the rotating column 6. Three liquid inlets 19 are evenly spaced on the upper part of one side of the liquid storage tank 1. An infusion pipe connected to the three liquid inlets 19 is installed on the upper part of the outer side of the liquid storage tank 1. One end of the infusion pipe is connected to an external water pump. The external water pump is connected to the microcontroller 15 through a wire. Two water-gathering grooves 20 are opened at the bottom of the liquid storage tank 1. Drain valves 21 are installed at the bottom of the two water-gathering grooves 20. Drain pipes 22 are connected to the bottom of the drain valves 21, so as to effectively add and drain liquid. This hydroponic device with controllable water depth effectively ensures that the roots of hydroponic plants are always submerged in liquid, thus guaranteeing the quality of hydroponic growth. Furthermore, the use of a water level sensor ensures stable adjustment, allowing for water depth control without manual watering. The device also features a simple design, convenient operation, and stable and reliable control and adjustment, meeting the performance requirements for hydroponic plant cultivation.
