Description

Technical Field

[0001] This utility model relates to the field of drip irrigation equipment technology, specifically to an automatic water-saving drip irrigation device for crops. Background Technology

[0002] Automatic water-saving drip irrigation systems for crops are a modern irrigation system that precisely controls water distribution, delivering water directly to the soil near the roots of crops to achieve water conservation and improve irrigation efficiency. However, existing automatic water-saving drip irrigation systems for crops are complex in structure and typically used on large farms; they are not suitable for small-area applications.

[0003] Today, people are increasingly concerned about food safety and quality. Some agricultural products purchased in the market may have pesticide residues and preservatives, so more and more people are starting to grow their own crops indoors, allowing them to control the entire growing process. However, the fast pace of modern life and the significant pressure of work and life make it difficult to tend to indoor crops in a timely manner. Furthermore, the limited indoor space makes existing water-saving drip irrigation systems unusable, and manual watering cannot guarantee sufficient water supply.

[0004] Therefore, it is necessary to invent an automatic water-saving drip irrigation device for crops to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic water-saving drip irrigation device for crops to address the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic water-saving drip irrigation device for crops, including a water tank, a conduit provided on the lower front of the water tank, a control mechanism provided on the front of the water tank, an inlet pipe fixedly installed on the upper end of one end of the water tank, a second solenoid valve fixedly installed at the front end of the inlet pipe, and an outlet pipe fixedly installed on the lower front of the water tank.

[0007] The control mechanism includes:

[0008] The controller is located on one side of the front of the water tank;

[0009] The No. 1 solenoid valve is fixedly installed at the front end of the outlet pipe, and the connecting end of the conduit is fixedly connected to the other end of the No. 1 solenoid valve.

[0010] A humidity detector is installed at one end of the front of the conduit, and the controller is electrically connected to the first solenoid valve and the humidity detector respectively via wires.

[0011] As a preferred embodiment of this utility model, a water level detector is fixedly installed at one end of the top of the water tank, and the probe of the water level detector is inserted through the inside of the water tank. The other end of the second solenoid valve is connected to an external water supply connector. The second solenoid valve and the water level detector are electrically connected to the controller through wires.

[0012] As a preferred embodiment of this utility model, the conduit has a T-shaped structure, and a number of equally spaced diversion joints are fixedly installed on the front side of the conduit. Each diversion joint is equipped with a valve at its top, and at least one diversion joint is equipped with a drip irrigation hose at its front end.

[0013] As a preferred embodiment of this utility model, several drip irrigation heads are fixedly installed on both sides of the drip irrigation hose at equal intervals. The drip irrigation heads have an L-shaped structure, with the water outlet of the drip irrigation head facing upwards. The drip irrigation heads are made of rigid plastic tubing.

[0014] As a preferred embodiment of this utility model, the humidity detector is inserted into the soil, the controller is connected to an external power source via a wire, the water tank is made of transparent plastic, and a lid is installed over the top opening of the water tank.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The control mechanism enables precise control of water distribution, allowing water to be directly delivered to the soil near the roots of crops. The humidity detector can monitor soil moisture in real time and feed the signal back to the controller. The controller controls the opening and closing of the No. 1 solenoid valve according to the set humidity threshold. When the soil moisture reaches a suitable level, the water supply is stopped, avoiding water waste caused by over-watering. Compared with the traditional flood irrigation method, it can greatly save water consumption, which is in line with the concept of water-saving irrigation. It is especially suitable for indoor planting and other scenarios where water resources need to be used more rationally. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The automatic water-saving drip irrigation device for crops shown includes a water tank 1. The water tank 1 serves as the water storage container for the entire drip irrigation device, providing a water source guarantee for irrigation. It has a certain capacity and can store an appropriate amount of water to meet the irrigation needs of crops within a certain period of time. It ensures that even if artificial watering cannot be done in time, there is enough water to maintain the normal operation of irrigation work, providing a basic support for the continuous and stable growth of indoor crops. A conduit 3 is set on the lower front of the water tank 1. The T-shaped structure design of the conduit 3 allows water to be evenly distributed to each diversion joint, ensuring the uniformity of irrigation. The even distribution of the diversion joints 31 ensures that each part of the crops can receive an appropriate amount of water. A control mechanism 2 is set on the front of the water tank 1. An inlet pipe 11 is fixedly installed on the upper end of one end of the water tank 1. A second solenoid valve 23 is fixedly installed at the front end of the inlet pipe 11. An outlet pipe 12 is fixedly installed on the lower front of the water tank 1.

[0027] Control mechanism 2 includes:

[0028] The controller 21 is located on one side of the front of the water tank 1. As the brain of the system, the controller 21 can intelligently adjust the opening and closing of the first solenoid valve 22 according to the data of the humidity detector 24, thereby automatically controlling irrigation.

[0029] The precise control of the solenoid valves can ensure the accurate distribution of water volume. Solenoid valve 22 controls the water outlet, and solenoid valve 23 controls the water source inlet. Solenoid valve 22 is fixedly installed at the front end of the water outlet pipe 12, and the connecting end of the conduit 3 is fixedly connected to the other end of solenoid valve 22.

[0030] Humidity detector 24 is located at one end of the front of conduit 3. Controller 21 is electrically connected to solenoid valve 22 and humidity detector 24 respectively via wires. Humidity detector 24 is directly inserted into the soil and can accurately monitor soil moisture, providing data support to controller 21 and ensuring that plants receive adequate water.

[0031] Furthermore, in the above technical solution, a water level detector 13 is fixedly installed at one end of the top of the water tank 1. The probe of the water level detector 13 is inserted through the inside of the water tank 1. The water level detector 13 can monitor the water level in the water tank 1 in real time. When the water level is lower than the set value, it can promptly notify the user to add water or automatically add water through the second solenoid valve 23. The other end of the second solenoid valve 23 is connected to the external water supply connector. The second solenoid valve 23 and the water level detector 13 are electrically connected to the controller 21 through wires.

[0032] Furthermore, in the above technical solution, the conduit 3 has a T-shaped structure, and several equally spaced diversion joints 31 are fixedly installed on the front of the conduit 3. Each diversion joint 31 is equipped with a valve 32 at its top. The valve 32 at the top of each diversion joint 31 can be controlled independently to adjust the water distribution in different areas to meet the needs of different plants, and to control the opening and closing of each diversion joint 31 individually. At least one diversion joint 31 has a drip irrigation hose 4 installed at its front end. The drip irrigation hose 4 delivers water to the roots of the crops, and the design of the drip irrigation head 41 ensures that the water can be evenly distributed around the plants, reducing water evaporation and loss.

[0033] Furthermore, in the above technical solution, several equally spaced drip irrigation heads 41 are fixedly installed on both sides of the drip irrigation hose 4. The drip irrigation heads 41 have an L-shaped structure with their outlets facing upwards. This unique structural design allows the water dripping from the drip irrigation heads 41 to fall precisely into the soil area above the crop roots. The water can penetrate along the soil to the area around the roots, maximizing the direct effect of water on the crop roots, improving the accuracy of drip irrigation, and preventing water from splashing onto other unnecessary places. The drip irrigation heads 41 are made of rigid plastic tubing. Compared with some softer materials that are easily deformed or damaged, rigid plastic tubing can maintain its shape and stable water output performance for a long time. It is not prone to clogging or cracking due to long-term water flow impact or minor external collisions, ensuring the long-term stable operation of the drip irrigation device, reducing the trouble of frequent repairs or replacements due to drip irrigation head failures, lowering usage and maintenance costs, extending the service life of the entire drip irrigation device, and improving the practicality and reliability of the device.

[0034] Furthermore, in the above technical solution, the humidity detector 24 is inserted into the soil, the controller 21 is connected to an external power source via a wire, the water tank 1 is made of transparent plastic, and the top opening of the water tank 1 is covered with a lid. The water tank 1 allows users to add water as needed, avoiding waste of water resources. The transparent plastic water tank allows users to see the water storage status in the tank intuitively, making it easy to replenish water in time. The design of the top opening and the lid makes it convenient for users to add water and clean the water tank. The lid can prevent dust and other impurities from entering.

[0035] The automatic water-saving drip irrigation device for crops provided by this utility model operates as follows:

[0036] First, based on the layout of the crops planted indoors, select a suitable and relatively stable location to place the drip irrigation device. Ensure that the device is placed stably, and at the same time, make it easy for components such as the conduit 3 and drip irrigation hose 4 to extend to each crop planting area, and facilitate connection to external water supply connectors (if available) and power supply (to power the controller 21).

[0037] Using the corresponding operation buttons or interface on controller 21 (depending on the controller type), appropriate soil moisture threshold parameters can be set according to the type of crop being grown, its growth stage, and the indoor growing environment. For example, when growing leafy vegetables such as lettuce, a relatively high soil moisture level may be set during the seedling stage, while the humidity threshold can be appropriately lowered during the maturity stage to meet their water requirements at different stages. Simultaneously, based on the capacity of water tank 1 and daily usage experience, an alarm value for low water level (if this function is supported) or an automatic water replenishment threshold can be set to ensure that water tank 1 can be replenished in a timely manner without overflowing.

[0038] During normal use, the device will operate automatically according to the set program. Users only need to periodically observe the working status of each component of the device and check the water level in the water tank 1. The water level can be visually judged through the transparent plastic water tank 1 to see if it is within the normal range. If the water level is too low and close to the water replenishment threshold, check whether the device has started the water replenishment mechanism normally (through the second solenoid valve 23). If water is not replenished normally, check whether the relevant components (such as the water level detector 13, controller 21, second solenoid valve 23, and connecting lines) are faulty. At the same time, observe whether there is any leakage in the drip irrigation hose 4 and whether the drip irrigation head 41 is dripping normally to ensure that the irrigation system is working properly.

[0039] As crops grow, their water requirements may change. For example, as they transition from the vegetative growth stage to the reproductive growth stage, the water needs of some crops will change. At this time, the soil moisture threshold parameter can be appropriately adjusted through the controller 21 to make irrigation more suitable for the current growth needs of the crops. In addition, if it is found that the growth status of crops in certain areas is not good (such as signs of water shortage and yellowing or waterlogging and root rot), the opening of the valve 32 on the corresponding diversion connector 31 can be manually adjusted to finely adjust the water distribution in that area, ensuring that each crop receives an appropriate water supply.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
