[0030] This disclosure provides a photovoltaic sprinkler device, see [link]. Figures 1-4As a basic embodiment of the photovoltaic sprinkler device disclosed herein, it includes a light sensor 8, a water supply module, a sprinkler module, a power generation module, and a control module. The light sensor 8 is a photoresistor, which provides feedback on the intensity of external sunlight by changing its resistance with light intensity. The water supply module includes a water storage tank 3, a first water pump 4, and a first flow switch 5. The outlet of the water storage tank 3 is connected to the inlet of the first water pump 4 via the first flow switch 5. A level sensor 10 is installed inside the water storage tank 3. The sprinkler module includes a sprinkler 6 and a second flow switch 7. The sprinkler 6 is connected to the outlet of the first water pump 4 via a second flow switch 7. The power generation module includes a photovoltaic module 1 and a power supply unit 2. The photovoltaic module 1 is connected to the power supply unit 2 to charge it. The power supply unit 2 is connected to a light sensor 8, a liquid level sensor 10, and the first water pump 4 to provide power. The control module 9 can be a PLC controller, which is electrically connected to the light sensor 8, liquid level sensor 10, photovoltaic module 1, power supply unit 2, sprinkler 6, and first water pump 4 to receive and receive signals from the aforementioned devices and control them. It should be noted that the sprinkler 6 is existing technology, and its specific structure is not limited. For example, the sprinkler 6 consists of several nozzles and a moving mechanism. The moving mechanism is a trolley, and the nozzles are adjustablely mounted on the trolley. The control module 9 can control the trolley to move the nozzles. The spray angle of the nozzles is adjustable to control the spray angle, range, water volume, etc. Furthermore, for ease of understanding... Figure 1 The dashed lines in the diagram indicate electrical connections and / or signal connections. Figure 1 The solid line in the middle represents a pipeline connection.

[0031] Based on the above basic embodiments, the photovoltaic sprinkler device disclosed herein detects the intensity of sunlight through a light sensor. When the detected light intensity meets the charging requirements, the signal can be transmitted to the control module 9. The control module 9 feeds back the signal to the power supply unit 2 and verifies whether the stored energy of the power supply unit 2 needs to be charged. If charging is required, the photovoltaic module 1 is controlled to charge and store the energy in the power supply unit 2, thereby enabling power supply to various electrical devices without the need to connect to the city's power system or for complex and cumbersome power layout, facilitating construction and subsequent maintenance. When sprinkler operation is required, the control module 9 can control the operation of the power supply unit 2, the sprinkler 6, and the first water pump 4 according to the settings to achieve automatic operation of the sprinkler operation. The entire sprinkler operation does not require manual intervention, saving manpower and improving the efficiency of the sprinkler operation. The sprinkler operation settings of the control module 9 can be set to perform timed sprinkler operation, or the light intensity can be detected by the light sensor 8. When the sunlight intensity is too high and the duration of the sunlight exceeds the set time, the control module 9 controls the sprinkler operation.

[0032] In some embodiments, see Figures 1-3The photovoltaic module 1 includes a photovoltaic panel 101, a mounting base 102, a first connecting rod 103, and a second connecting rod 104. The photovoltaic panel 101 may be composed of high-efficiency crystalline silicon solar cells, ultra-white textured tempered glass, EVA (ethylene-vinyl acetate copolymer) plastic, a transparent TPT (polyvinyl fluoride composite film) backsheet, and an aluminum alloy frame. The back of the photovoltaic panel 101 is provided with a matching slide rail 105 and a slider 106. One end of the first connecting rod 103 is fixedly connected to the mounting base 102, and the other end is hinged to the photovoltaic panel 101. One end of the second connecting rod 104 is fixedly connected to the mounting base 102, and the other end is hinged to the slider. 106, and the second connecting rod 104 is a telescopic rod, suitable for controlling the angle between the photovoltaic panel 101 and the mounting base 102 by adjusting the length of the second connecting rod 104. The mounting base 102 is rotatably mounted on the rotating platform 107. By adjusting the telescopic extension of the second connecting rod 104 and the rotation of the rotating platform 107, the position of the photovoltaic panel 101 can be adjusted so that sunlight can shine on the photovoltaic panel 101 at a vertical angle, improving the power generation effect of the photovoltaic panel 101. The size of the photovoltaic panel 101 is selected according to actual needs. For example, a 100mm*100mm photovoltaic panel 101 can be used, which can generate 160W of power per day. See also... Figure 2 and Figure 3 The second connecting rod 104 is inclined, so that the thrust generated by the second connecting rod 104 during the extension and retraction process is never perpendicular to the photovoltaic panel 101, thus forming a component force that pushes the slider 106 to slide on the slide rail 105, preventing the mechanism from jamming. Furthermore, a first limiting block 108 and a second limiting block 109 are respectively provided at both ends of the slide rail 105 to limit the sliding of the slider 106.

[0033] In some embodiments, see Figure 1 The bottom of the water storage tank 3 is funnel-shaped, and its drain outlet is located at the lowest point of the bottom to facilitate drainage. The liquid level sensor 10 includes a first liquid level sensor 1001 and a second liquid level sensor 1002 arranged vertically. When the first liquid level sensor 1001 detects a liquid level signal, it means that the water storage tank 3 has reached the highest liquid level, and there is no need to add water or stop the water adding operation. When the second liquid level sensor 1002 does not detect a liquid level signal, even if the water in the water storage tank 3 is insufficient, a water adding operation is required.

[0034] In some embodiments, the water storage tank 3 is connected to a water supply pipe 18, which is equipped with a fourth flow switch 19 to replenish the water in the water storage tank 3 when the water level is insufficient. The water supply pipe 18 can be connected to a tap water pipe, and / or an additional rainwater collection tank (not shown in the figure) can be provided to collect rainwater on rainy days and replenish the water storage tank 3 after filtration.

[0035] In some embodiments, see Figure 1 The water supply module also includes a second water pump 11. The first water pump 4 and the second water pump 11 have the same structure, both consisting of a pump casing, pump shaft, impeller, suction pipe, discharge pipe, foot valve, control valve, priming funnel, and pump base. The second water pump 11 is arranged in parallel with the first water pump 4, and the outlet ends of the second water pump 11 and the first water pump 4 are respectively equipped with a first check valve 12 and a second check valve 13. The second water pump 11 is electrically connected to the control module 9. The second water pump 11 can be used as a backup water pump. When the first water pump 4 fails, the second water pump 11 can be activated to increase the reliability of the device; or, when the water supply pressure is insufficient, the first water pump 4 and the second water pump 11 can be activated simultaneously to increase the watering efficiency.

[0036] In some embodiments, an overflow valve 14 is also included. The inlet end of the overflow valve 14 is connected to the pipeline between the second flow switch 7 and the first water pump 4, and the outlet end is connected to the water storage tank 3. This allows the overflow valve 14 to release pressure when the pressure in the pipeline exceeds the safe pressure, ensuring the safe use of the device.

[0037] In some embodiments, see Figure 1 A filter 15 is installed between the first flow switch 5 and the first water pump 4 to filter the water discharged from the water storage tank 3, preventing impurities from damaging the first water pump 4 and the sprinkler 6, and ensuring the reliability of the device. The filter 15 is mainly composed of a shell, a multi-element filter element, a backwashing mechanism and a differential pressure controller. The interior of the shell is divided into upper and lower parts by a partition. The upper part is equipped with multiple filter elements, which effectively utilizes space and reduces the volume of the filter. The lower part is equipped with a backwashing suction cup to ensure its efficient operation.

[0038] In some embodiments, see Figure 1 A flow meter 16 and a third flow switch 17 are sequentially installed between the second flow switch 7 and the sprinkler 6. The flow meter 16 is electrically connected to the control module 9. The flow meter 16 measures the amount of water supplied to the sprinkler 6 to achieve accurate water volume and avoid water waste. When the sprinkler operation stops, both the second flow switch 7 and the third flow switch 17 are turned off, so that the pipeline of the flow meter 16 is in a completely zero-flow state, avoiding zero-point offset caused by pressure changes, and also playing a shut-off role to improve measurement accuracy.

[0039] In some embodiments, the first flow switch 5, the second flow switch 7, the third flow switch 17, and the fourth flow switch 19 are all solenoid valves, and each solenoid valve is electrically connected to the control module 9, thereby enabling precise control of each switch through the control module 9.

[0040] In some embodiments, see Figure 1 and Figure 4The power supply unit 2 includes a battery 201, a charge / discharge controller 202, and a transformer mechanism. The photovoltaic module 1 is connected to the battery 201 through the charge / discharge controller 202 to control the charging and discharging of the battery 201. The transformer mechanism is connected to the battery 201 and includes a DC / DC converter 203 and an inverter 204. The DC / DC converter 203 can boost and / or transform the DC voltage to adapt it to the DC operating voltage of some components. For example, the DC / DC converter 203 is connected to the electromagnetic control terminals of the light sensor 8, the first liquid level sensor 1001, the second liquid level sensor 1002, and the first flow switch 5, the second flow switch 7, the third flow switch 17, and the fourth flow switch 19. The inverter 204... 4. The DC voltage is converted into a stable AC voltage to adapt it to the AC operating voltage of some components. For example, the inverter 204 is connected to the sprinkler 6, the first water pump 4, and the second water pump 11. In addition, the battery 201 is equipped with a power detection module. In order to ensure the realization of the most basic function of the sensor of the photovoltaic sprinkler device of this disclosure, when the power of the battery 201 is detected to be less than the set value, the control module 9 will not perform the relevant sprinkler operation until the photovoltaic module 1 generates solar power to charge the battery 201. The sprinkler operation will resume only when the power is detected to reach the set value that allows the sprinkler operation to be performed. This avoids the complete paralysis of the photovoltaic sprinkler device of this disclosure due to the low power of the battery 201, and ensures the reliability of the device.

[0041] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
