Description

TECHNICAL FIELD

[0001] The utility model belongs to solar power supply and daily tracking control technical field, specifically related to a kind of solar power supply and daily function's sprinkling irrigation mechanism. BACKGROUND

[0002] With the continuous development of daily tracking system and solar sprinkling irrigation field, the existing technical solutions have been widely applied.However, these products still have some problems in actual use.For example, the existing daily tracking system usually adopts a complex sensor network to realize accurate tracking of the position of the sun, which not only increases the cost of the system, but also may cause low tracking efficiency due to the accuracy and stability problems of the sensor.The solar sprinkling irrigation system can utilize solar energy resources, but its performance will significantly decrease in rainy weather or insufficient sunlight, affecting the irrigation effect.

[0003] To solve these problems, there have been some attempts, such as using a dual-voltage integrated comparator combined with a photoresistor to simplify the tracking system, and using a main and backup power supply automatic switching and auxiliary power supply to improve the stability and tracking ability of the system in adverse weather conditions.Although these methods have improved related aspects to some extent, they still have limitations, such as decreased tracking accuracy in extreme weather conditions and excessive dependence on backup power supply.

[0004] Specifically, according to the search, a daily solar photovoltaic support system with publication number CN216599506U was disclosed on May 24, 2022.The design uses two photoresistors and a dual-voltage integrated comparator to detect and track light intensity, and uses main and backup power supply automatic switching and auxiliary power supply to improve system stability.Although it can achieve basic daily tracking function, due to the limited response speed and accuracy of the photoresistor to light intensity changes, the tracking accuracy may decrease under rapidly changing light conditions.In addition, the design has high dependence on backup power supply, which may face the problem of backup power supply depletion in continuous rainy weather.

[0005] According to the search, a daily power generation system with publication number CN220067328U was disclosed on November 21, 2023.The product uses an azimuth-elevation type turntable structure, and rotates the solar cell panel 340° through a stepping motor driven worm gear.Although it has the function of automatically adjusting the orientation of the solar cell panel according to the direction of sunlight, its power generation efficiency will significantly decrease in rainy weather or insufficient sunlight, affecting the normal operation of the sprinkling irrigation system.In addition, the design has high structural complexity, which may increase maintenance cost and failure rate.

[0006] The above problems show that the daily tracking system and the solar energy sprinkling irrigation system in the market are difficult to effectively deal with complex weather conditions and new requirements for stable power supply and efficient tracking. Therefore, the utility model provides a sprinkling irrigation mechanism with daily function and solar power supply to overcome these shortcomings and provide a new solution which is more intelligent, efficient and adaptable to changing environment.

[0029] The working principle is as follows:

[0030] 1. Daily tracking of the solar cell panel: The solar cell panel 1 is installed on the main support 2 through the rotating shaft 3. The driving motor 4 drives the rotating shaft 3 to rotate through the gear 28. The photosensitive sensor 5 detects the direction of sunlight and sends a signal to the main control unit 6, which controls the rotation of the driving motor 4 according to the signal of the photosensitive sensor 5, so that the solar cell panel 1 always faces the sunlight. The balance arm 12 and the counterweight 13 are used to keep the balance of the solar cell panel 1, and the angle sensor 14 and the encoder 15 are used to detect the rotation angle of the rotating shaft 3 and the rotation state of the driving motor 4, and the main control unit 6 adjusts the rotation speed and direction of the driving motor 4 according to the detection data.

[0031] 2. Operation of the sprinkler system: The sprinkler system includes fixed nozzles 7 and rotating nozzles 8, the fixed nozzles 7 are used for irrigation in fixed areas, and the rotating nozzles 8 are used for irrigation in a large area. The stepping motor 11 drives the rotation of the rotating nozzles 8, and the main control unit 6 adjusts the operating parameters of the sprinkler system, such as the water spraying amount and frequency of the nozzles, according to the data of the environmental monitoring module. The water pump 9 draws water from the water storage tank 10 and delivers it to the nozzles through the pipeline 30.

[0032] 3. Backup power supply and charge management: When the solar cell panel 1 cannot provide power, the energy storage battery 19 provides backup power, and the charge management module 20 manages the charging and discharging process of the energy storage battery 19 to ensure that the system can still operate normally in the absence of sunlight.

[0033] 4. Environmental monitoring and fault detection: Temperature sensor 21, humidity sensor 22, and light sensor 23 detect environmental parameters and send signals to the main control unit 6, which adjusts the operating parameters of the sprinkler system according to the environmental parameters. Fault detection module 24 detects the operating state of the system and sends a fault alarm signal to the main control unit 6, which is connected to external control devices through communication module 18, realizing remote monitoring and control.

[0034] Specific application scenarios:

[0035] Suppose in a modern agricultural park, efficient irrigation of large farmland is needed. The sprinkler mechanism is installed in the center of the farmland, and the main support 2 is fixed on the ground. During the day, the light sensor 5 detects the direction of sunlight and controls the rotation of the drive motor 4 through the main control unit 6, so that the solar panel 1 always faces the sunlight, maximizing the power generation efficiency of the solar panel 1. The sprinkler system automatically adjusts the water spray volume and frequency of the sprinkler according to the data of the environmental monitoring module, ensuring uniform irrigation of the farmland under different weather conditions. When the solar panel 1 cannot provide power at night or on cloudy days, the energy storage battery 19 and the charging management module 20 ensure the continuous operation of the sprinkler system. The fault detection module 24 monitors the operating state of the system in real time, and sends an alarm signal as soon as a fault is found, so that the park management personnel can timely repair and ensure the stable operation of the system.
