Description

Technical Field

[0001] The utility model relates to the technical field of solar power generation, in particular to a solar off-grid water pump device. Background Art

[0002] The solar off-grid water pumping device is a system that uses solar energy to pump water. It does not require traditional electricity or other energy sources, but relies entirely on solar energy to work. The application of this system is very important for areas where the power supply is unstable or lacks power resources.

[0003] The existing Chinese patent literature, the patent with the authorized patent number CN209228559U, discloses a solar off-grid water pump device, including a ground, a solar panel and a pool, the surface of the ground is installed with a pillar, the top of the pillar is installed with a solar panel, the right side of the pillar is installed with a box, the inner cavity of the box is installed with an MPPT controller, the right side of the MPPT controller is installed with a single-chip microcomputer, the right side of the single-chip microcomputer is installed with a battery, the left and right side walls of the inner cavity of the box are respectively installed with an inverter and a time relay, the top of the inner cavity of the box is installed with a wireless module, the right side of the box is placed with a pool, and the inner cavity of the pool is installed with a water pump.

[0004] Although the existing solar off-grid water pump device uses solar panels to absorb sunlight and convert it into electrical energy to power the water pump to form a fountain, it is both energy-saving and practical and suitable for wide promotion. However, in actual use, due to the influence of the outdoor environment, dust and impurities are easily accumulated on the surface of the solar panel, resulting in a decrease in the light energy conversion rate. Solar energy is the main source of power for the entire off-grid water pump device. If its conversion rate decreases, the power that the device can receive and use will be reduced, resulting in the water pump being unable to operate normally or even unable to start. Insufficient power supply will also cause the water pump to operate unstably, with intermittent pauses or uneven operating speeds, which will affect the effect and stability of the fountain. Although regular manual cleaning is effective, the operation is cumbersome and inconvenient. Therefore, this device needs further improvement.

[0005] Therefore, it is necessary to provide a new solar off-grid water pump device to solve the above-mentioned technical problems. Utility Model Content

[0026] The water supply and flushing mechanism includes a three-way pipe 13, a filter cartridge 14, a connecting pipe 15, a telescopic pipe 16 and a nozzle 17. The three-way pipe 13 is fixedly connected to the water outlet end of the water pump 4, the filter cartridge 14 is fixedly installed on one side of the protective shell 12, the connecting pipe 15 is fixedly connected to one of the water outlet ends of the three-way pipe 13, the water outlet end of the connecting pipe 15 extends into the filter cartridge 14, the telescopic pipe 16 is fixedly connected to the filter cartridge 14, the water outlet end of the telescopic pipe 16 penetrates into the protective shell 12, the nozzle 17 is fixedly connected to the water outlet end of the telescopic pipe 16, and the water spraying end of the nozzle 17 faces the solar cell panel 5.

[0032] It is worth noting that the circuits, electronic components and modules involved in the utility model are all prior arts, which can be fully implemented by those skilled in the art.

Among them, the model of the time relay is jsz6-2, the model of the single-chip controller is MPC5554, the model of the water level meter is CKTC-601, the wireless module is a 4G communication module, and the model of the inverter is SP-GTI.

[0033] The working principle of the solar off-grid water pump device provided by the utility model is as follows:

[0034] When in use, first, the solar panel 5 cooperates with the MPPT controller 6 and the inverter to maximize the conversion of solar energy into electrical energy, and the electrical energy is stored in the battery 8 to power the electrical components. The time relay can be used to cooperate with the single-chip controller 7 to control the start and stop of the variable frequency water pump 4. The water pump 4 can pump water in the pool 2 into the water tray and spray it to achieve the effect of a fountain. When the time setting range is exceeded, the single-chip controller 7 will automatically turn off the water pump 4. When the water level in the pool 2 is low, when the water level data detected by the water level meter is less than the preset value, the data will be fed back to the single-chip controller 7. The single-chip controller 7 will feed back the signal to the external equipment through the wireless module to remind the staff to replenish the water source in time. The device has a simple structure, saves energy, and is highly practical.

[0035] When cleaning the solar panel 5, the time relay cooperates with the single-chip controller 7 to control the solenoid valve 20, the water pump 4 and the swing-type motor 10 to start running. When the transport water pump 4 pumps water out, part of the water will enter the connecting pipe 15 along the other water outlet end of the three-way pipe 13, and the water will be transported to the filter cartridge 14 through the connecting pipe 15. Impurities in the water will be filtered out by the filter bag 18, and the filtered water will flow out along the telescopic tube 16. Then the water will be sprayed out from the nozzle 17 to wash away the dust and impurities attached to the surface of the solar panel 5. At the same time, the output shaft of the swing-type motor 10 will drive the assembly frame 11 and the brush plate 9 to swing back and forth to clean the solar panel 5. In this way, the cleaning of the solar panel 5 is realized, and the cleaning is more labor-saving and convenient, and the accumulation of dust and impurities is avoided to cause a decrease in the light energy conversion rate. When not cleaning, the brush plate 9 is located on the left or right side of the solar panel 5 to avoid blocking the solar panel 5.

[0036] Compared with the related art, the solar off-grid water pump device provided by the utility model has the following beneficial effects:

[0037] The utility model provides a solar off-grid water pump device. Through the arranged pillars 1, pool 2, box body 3, water pump 4, solar panel 5, MPPT controller 6, single chip controller 7, battery 8, brush plate 9, motor 10, time relay, wireless module and the like, a novel solar off-grid water pump device can be formed. The solar panel 5 can be easily cleaned to avoid the accumulation of dust and impurities which may lead to a decrease in light energy conversion rate, which is beneficial to the normal operation of the device. The solar panel 5 can be cleaned and rinsed by the arranged water supply and flushing mechanism, so as to improve the cleaning effect. The arranged filter bag 18 can filter impurities in the flushing water to avoid clogging of the nozzle 17. The arranged barrel cover 19 can be opened later to clean or replace the filter bag 18. The arranged collection box 22 can be used to receive sewage flowing downward when the solar panel 5 is cleaned to avoid sewage flowing everywhere.
