Technical Field
[0001] This utility model belongs to the field of agricultural engineering technology, and more specifically, it relates to an automatic water distributor for precision drip irrigation suitable for greenhouses. Background Technology
[0002] An automatic water distributor for precision drip irrigation in greenhouses is a device used in greenhouse irrigation systems. It can precisely distribute water according to the needs of crops and environmental conditions, achieving efficient and water-saving irrigation. Based on preset programs or information from sensors, such as soil moisture and crop growth stage, it can precisely control the water output and irrigation time of each drip irrigation head to ensure that crops receive adequate water and avoid over-irrigation or under-irrigation. However, currently used automatic water distributors are easily affected by terrain and lack the ability to cope with the complex terrain in greenhouses. They are difficult to bend and adapt to, and excessive pipe bending can lead to poor water flow or even blockage, affecting the uniformity and effectiveness of drip irrigation. Therefore, there is a need for a new type of automatic water distributor for precision drip irrigation in greenhouses. Utility Model Content

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Example:
[0024] As attached Figure 1 To be continued Figure 5 As shown:
[0025] This utility model provides an automatic water distributor for precision drip irrigation suitable for greenhouses, including an insulated outer shell 1, a filter tank 6, and a connecting pipe A13;
[0026] A sealing cover 2 is movably connected to the inner side of the upper end of the heat insulation shell 1, and a water inlet pipe 5 is connected to the right side of the heat insulation shell 1. A waterproof shell 3 is connected to the left side of the heat insulation shell 1. A controller is installed inside the waterproof shell 3. A fixing bracket 4 is provided at the lower end of the heat insulation shell 1. A filter tank 6 is placed at the lower end of the heat insulation shell 1, and a drain pipe 10 is connected to the upper end of the filter tank 6. The upper end of the drain pipe 10 passes into the interior of the heat insulation shell 1. A water pump 9 is installed inside the heat insulation shell 1. The water pump 9 is connected to the drain pipe 10. The water pump 9 is electrically connected to the controller inside the waterproof shell 3. A sealing interface 14 is installed on the front side of the connecting pipe A13, and two sets of connecting pipes B16 are connected to the left and right sides of the connecting pipe A13 respectively.
[0027] Among them, such as Figure 2As shown, a heating plate 8 is installed inside the insulation shell 1, and a temperature sensor is also installed inside the insulation shell 1. The heating plate 8 and the temperature sensor are electrically connected to the controller inside the waterproof shell 3. The temperature sensor can monitor the temperature inside the insulation shell 1 in real time. When the temperature is lower or higher than the set value, it can promptly send a signal back to the controller. The controller can precisely control the working state of the heating plate 8 based on the received signal, such as turning it on, off, or adjusting the heating power, so that the temperature of the water inside the insulation shell is maintained within the suitable range required for crop growth, which is beneficial to the growth and development of crops.
[0028] Among them, such as Figure 3 As shown, the filter tank 6 has two sets of filter screens 11 installed inside, and an activated carbon layer 12 is provided between the two sets of filter screens 11. A hose 7 is connected to the front of the filter tank 6, and a sealing interface 14 is installed on the hose 7. The water can be filtered in stages through the two sets of filter screens 11. The first set of filter screens 11 intercepts larger particles of impurities, and the second set of filter screens 11 filters smaller particles of impurities. The activated carbon layer 12 can focus on adsorbing small particles and harmful substances such as organic matter, odors, and pigments in the water, thereby improving the filtration effect of the entire filter tank 6 and providing a cleaner water source for subsequent drip irrigation.
[0029] Among them, such as Figure 4 and Figure 5 As shown, the rear side of connecting pipe A13 is movably connected to the sealing interface 14 on the hose 7. A set of corrugated pipes 17 are connected to the outer side of each of the four sets of connecting pipes B16 on connecting pipe A13, and connecting pipes C18 are connected to the corrugated pipes 17. A set of electrically controlled valves 19 are installed on each of the four sets of connecting pipes C18. The electrically controlled valves 19 are electrically connected to the controller inside the waterproof housing 3. A set of T-shaped pipes 22 are connected to each of the four sets of connecting pipes C18. A drip irrigation nozzle 23 is installed on the lower side of each of the four sets of connecting pipes C18. A set of fixing rods 20 are installed on the lower side of each of the four sets of connecting pipes C18, and a humidity sensor 21 is installed on the fixing rod 20. The humidity sensor 21 is electrically connected to the controller inside the waterproof housing 3. Water is controlled through the four sets of connecting pipes B16. The multi-branch irrigation system can simultaneously irrigate different areas or crop types within a greenhouse, making it particularly suitable for the differentiated planting needs in greenhouses. It avoids the resource waste of traditional flood irrigation. The electrically controlled valve 19 is linked with the controller and can dynamically adjust the flow rate of each branch based on real-time data from the humidity sensor 21. When the soil moisture in a certain area is below the threshold, the controller automatically opens the corresponding electrically controlled valve 19, and vice versa, achieving on-demand water supply. Precise adjustment improves water-saving efficiency and avoids root diseases caused by over-irrigation. The corrugated pipe 17 is conducive to adapting to complex terrains within the greenhouse, such as high and low ridges and obstacles, avoiding pressure loss or blockage caused by pipe bends. Furthermore, the UV resistance and aging resistance of the corrugated pipe 17 extend its service life and reduce replacement costs.
[0030] Among them, such as Figure 5 As shown, each of the four sets of T-shaped pipes 22 has a set of electrically controlled valves 24 installed on its upper side. The upper end of the T-shaped pipes 22 is connected to an atomizing nozzle 25. The electrically controlled valves 24 are electrically connected to the controller inside the waterproof housing 3. The atomizing nozzles 25 can provide atomized spraying mode. In conjunction with the drip irrigation nozzles 23, it can meet the water requirements of different crops at different growth stages. For example, for some crops that require high humidity or in dry seasons, the atomizing nozzles 25 can increase air humidity to create a suitable growing environment for the crops. In other cases, drip irrigation mode can be used to directly deliver water to the roots of the crops, improving the utilization rate of water resources.
[0031] The specific usage and function of this embodiment are as follows:
[0032] like Figures 1 to 5 As shown, in this invention, the temperature inside the insulation shell 1 can be monitored in real time by a temperature sensor. When the temperature is lower or higher than the set value, the sensor can promptly send a signal to the controller. The controller then precisely controls the working state of the heating plate 8 based on the received signal, such as turning it on, off, or adjusting the heating power. This keeps the water temperature inside the insulation shell within a suitable range required for crop growth, which is beneficial for crop growth and development. The atomizing nozzle 25 provides an atomizing spray mode, which, in conjunction with the drip irrigation nozzle 23, can meet the water requirements of different crops at different growth stages. For example, for some crops that require high humidity or in dry seasons, the atomizing nozzle 25 can increase air humidity to create a suitable growing environment for the crops. In other cases, drip irrigation can be used to directly deliver water to the crop roots, improving water resource utilization.
