[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-3As shown, one embodiment of this utility model provides a rainwater harvesting and pasture irrigation system for photovoltaic power generation panels in desert areas, including a photovoltaic support, a solar power panel 4, a water collection tank 7, a water storage tank 8, and an irrigation component; the solar power panel 4 is installed at an angle on the photovoltaic support; the water collection tank 7 is installed on the photovoltaic support and is lower than the bottom of the solar power panel 4, for collecting rainwater that slides off the solar power panel 4; the water storage tank 8 is lower than the water collection tank 7, and the water storage tank 8 and the water collection tank 7 are connected by a water delivery pipe 10; the irrigation component includes a water delivery mechanism and a drip irrigation mechanism, the drip irrigation mechanism is laid in the pasture area, and the water delivery mechanism is used to draw water from the water storage tank 8 and deliver it to the drip irrigation mechanism.

[0025] In this embodiment, when it rains in the pastoral area, rainwater drips onto the solar panel 4. The rainwater dripping onto the solar panel 4 flows into the water collection tank 7, and then the rainwater in the water collection tank 7 flows into the water storage tank 8 through the water supply pipe 10, thus completing the collection of rainwater. Because the solar panel 4 has a large surface area, it can collect a lot of rainwater on rainy days.

[0026] When irrigation of the pasture is needed, the water delivery mechanism is activated, which draws water from the water storage tank 8 and delivers it to the drip irrigation system to irrigate the pasture.

[0027] As can be seen, in this embodiment, solar panels 4 are used to quickly collect rainwater, which is then stored in a water tank 8. A water delivery mechanism then pumps the water from the water tank 8 and delivers it to the drip irrigation system for irrigating pasture. The electricity generated by the solar panels 4 also powers the water pump 9 in the water delivery system. This method of collecting solar energy and converting it into electricity to power the water delivery system eliminates reliance on traditional fossil fuels, reduces environmental pollution, and achieves self-sufficiency in clean energy. Furthermore, the large surface area of ​​the solar panels 4 allows for rapid rainwater collection, maximizing the use of scarce rainfall. Combined with drip irrigation technology, this addresses the difficulty of irrigating pasture in desert areas, improves water resource utilization efficiency, and provides an efficient and sustainable solution for pasture irrigation in desertified pastoral areas.

[0028] In this embodiment, the water delivery mechanism includes a water pump 9, an inlet pipe 11, and an outlet pipe 12. The water pump 9 is installed on the top of the water storage tank 8. One end of the inlet pipe 11 is connected to the inlet of the water pump 9, and the other end extends into the interior of the water storage tank 8 and is close to the inner bottom wall of the water storage tank 8. One end of the outlet pipe 12 is connected to the outlet of the water pump 9, and the other end is connected to the drip irrigation mechanism for supplying water to the drip irrigation mechanism.

[0029] It is important to understand that the bottom of the water inlet pipe 11 is close to the inner bottom wall of the water storage tank 8. This is to maximize the extraction of water from the water storage tank 8 so that the water in the tank can be fully utilized.

[0030] It should be noted that the water storage tank 8 can typically be buried in the land of the pasture to be irrigated, while the water collection tank 7 is installed on the photovoltaic support, making the water collection tank 7 higher than the water storage tank 8. The bottom of the water collection tank 7 has an outlet, and the first end of the water supply pipe 10 is connected to the outlet at the bottom of the water collection tank 7, while the second end is connected to the water storage tank 8. The first end of the water supply pipe 10 is higher than the second end. In this way, rainwater in the water collection tank 7 flows naturally into the water storage tank 8 under gravity through the water supply pipe 10, eliminating the need for a water pump and saving on electricity costs.

[0031] Of course, a water pump can also be used to complete the hydraulic transport between the water collection tank 7 and the water storage tank 8, and a photovoltaic system can be used to power the water pump.

[0032] In this embodiment, the drip irrigation mechanism includes a water collection pipe 14 and multiple drip irrigation tapes 13. The water collection pipe 14 is laid on the ground of the pasture area to be irrigated. The end of the water outlet pipe 12 away from the water pump 9 is connected to the water collection pipe 14. Multiple valves are installed on the water collection pipe 14 along its axial direction. The outlet of each valve is connected to a drip irrigation tape 13. The drip irrigation tape 13 is also laid on the ground of the pasture area to be irrigated.

[0033] The water pump 9 draws rainwater from inside the water collection tank 7 and pumps it into the water collection pipe 14. Then, the valve on the water collection pipe 14 is opened, and the rainwater flows further into the drip irrigation tape 13, thereby providing precise irrigation for the pasture.

[0034] In this embodiment, as Figure 3 As shown, the water collection tank 7 is elongated and narrower at the bottom than at the top, so as to drain the water inside the water collection tank 7 to the maximum extent, making it easier for rainwater in the water collection tank 7 to flow into the water supply pipe 10.

[0035] Furthermore, the top of the water collection tank 7 is open, and the lowest end of the solar panel 4 is higher than and close to the top opening of the water collection tank 7.

[0036] In some embodiments, such as Figure 3 As shown, a dustproof plate 701 is installed on the water collection tank 7 to cover the opening at the top of the water collection tank 7. The dustproof plate 701 is an arc-shaped plate, with its first side connected to the side of the top of the water collection tank 7 away from the solar panel 4, and its second side close to the solar panel 4. The second side of the dustproof plate 701 is higher than its first side. That is, the dustproof plate 701 is curved towards the side where the solar panel 4 is located. In this way, the dustproof plate 701 can effectively prevent dust from entering the water collection tank 7, reducing the probability of sand and dust being blown into it.

[0037] In some embodiments, a filter screen for filtering impurities is installed inside the outlet at the bottom of the water collection tank 7, and one end of the water supply pipe 10 is connected to the outlet at the bottom of the water collection tank 7. The filter screen effectively filters out sand and other impurities in the rainwater, preventing sand and impurities from entering the water storage tank 8, thereby avoiding clogging of the drip irrigation tape 13.

[0038] In some embodiments, a filter device, such as a disc filter or a mesh filter, is installed at the outlet at the bottom of the water collection tank 7. Disc filters or mesh filters are small in size, compact in structure, flexible in installation, and can effectively remove impurities and particulate matter from the water.

[0039] In this embodiment, the photovoltaic support includes a support base 1, a vertical frame 2, and a support frame 3. The vertical frame 2 is vertically installed on the support base 1, and the support frame 3 is inclinedly installed between the support base 1 and the vertical frame 2. The solar power panel 4 is installed on the support frame 3.

[0040] It should be noted that a photovoltaic power generation system typically includes a charge controller 5, a battery 6, and an inverter. In this embodiment, as... Figure 1 As shown, the charging controller 5 is mounted on the back of the solar panel 4, and the battery 6 is placed on the support base 1. The positive and negative terminals of the solar panel 4 are connected to the positive and negative terminals of the charging controller 5, respectively, and the positive and negative terminals of the charging controller 5 are then connected to the positive and negative terminals of the battery 6, respectively. The positive output terminal of the charging controller 5 is connected to the positive input terminal of the inverter, and the negative output terminal is connected to the negative input terminal of the inverter.

[0041] The function of the solar panel 4 is to convert solar radiation energy into electrical energy. The charge controller 5 is responsible for controlling the operating status of the entire power supply system and provides overcharge and over-discharge protection for the battery 6. The charge controller 5 can adjust the voltage and current output of the solar panel to match the charging requirements of the battery 6, preventing damage to the battery 6 due to overcharging or over-discharging, thereby extending the battery 6's lifespan. When the electrical energy generated by the solar panel 4 exceeds the immediate needs of the equipment, the excess electrical energy is guided by the charge controller 5 to the battery 6 for storage. The inverter converts the DC power generated by the solar panel 4 into AC power.

[0042] In this embodiment, the water pump 9 can be either an AC pump or a DC pump. When using an AC pump, the DC power needs to be converted into AC power by an inverter first.

[0043] It should be noted that in this embodiment, there is no specific limit to the number of water supply pipes 10 and water pumps 9. The specific number should be reasonably selected according to the actual situation.

[0044] In some embodiments, a control box is installed on the support base 1. The control box includes a main control board, and a relay module inside the water pump 9 is signal-connected to the main control board. The main control board is responsible for receiving remote commands and sending signals to control the opening and closing of the relays, thereby controlling the water pump. The relay module is used to control the power supply to the water pump 9.

[0045] Alternatively, common control boards include Raspberry Pi and Arduino. These control boards can be programmed to control the relay module, thereby enabling remote control of the water pump 9.

[0046] The communication module is used to enable data transmission between the main control board and remote devices (such as mobile phones and computers). Common communication modules include NB-IoT modules, which are suitable for remote areas with poor network coverage.

[0047] Remote control terminals can be mobile apps, web interfaces, etc. Users can send control commands through these terminals to remotely control the water pump.

[0048] In this way, users can send commands to turn water pump 9 on or off via a mobile app or web interface. Upon receiving the remote command, the communication module transmits it to the main control board. The main control board then controls the relay module to open and close based on the received command. The relay module controls the power supply to the water pump, thus turning it on or off. This allows users to remotely control water pump 9 to achieve automated irrigation based on actual weather conditions.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components.
