Embodiment Construction

[0015] combine figure 1 , 2 , the present invention mainly includes photothermal power generation system 1, frequency conversion controller 2, AC motor 3, water pump 4, water tank 5, low water level sensor 15, middle water level sensor 16 and high water level sensor 17, wherein the photothermal power generation system 1 includes a butterfly reflector 6, a secondary lens 7, a disc radiator 8, a filter layer 9, a thermal infrared photovoltaic cell 10, a reflector 11, a combustion chamber 12, and a heat dissipation device 13. When the water level of the water tank is lower than the low water level sensor 15, the solenoid valve 14 is opened, gas is passed to the combustion chamber 12, and the heating disk radiator 8 is ignited, so that the output power of the photovoltaic power generation system 1 is increased, thereby increasing the water pumping of the photovoltaic water pump system If it is still lower than the lower water level sensor 15, increase the opening of the solenoid ...

Abstract

The invention discloses a day-and-night photovoltaic pump system with no storage battery and belongs to the technical field of solar photovoltaic and fuel chemical energy usage. The system mainly comprises a solar-thermal power generation system, a variable frequency controller, an alternating current motor, a water pump, a water tank, a low water level sensor, a medium water level sensor and a high water level sensor, wherein the solar-thermal power generation system comprises a butterfly type reflector, a secondary lens, a disk radiator, a filter layer, a thermal infrared light battery, a reflector, a combustion chamber and a cooling device. The efficiency of the solar-thermal power generation system is higher than that of an ordinary solar photovoltaic power generation system, and same output power needs few photovoltaic batteries, and accordingly, the cost of the whole system is reduced. The photovoltaic pump system with no storage battery is environment friendly and can operate day and night, and the defect that the photovoltaic pump system with no storage battery cannot pump water in rainy days or at nights is overcome. Simultaneously, the photoelectric conversion efficiency of the photovoltaic batteries in prior photovoltaic pump systems with no storage battery is improved and the size of the water tank is reduced.

Description

technical field [0001] The invention relates to a battery-free thermal photovoltaic water pump system, which belongs to the technical field of utilization of solar photovoltaic and fuel chemical energy. Background technique [0002] In rural and remote areas without electricity supply, electricity supply is required for irrigation. The emergence of photovoltaic water pumping system has solved the problem of drinking water and agricultural water in these areas to a certain extent. [0003] At present, photovoltaic water pump systems are divided into two types: those with batteries and those without batteries. Although the photovoltaic water pump system equipped with batteries can operate when there is no sunlight (cloudy or at night), the batteries have a short service life and require regular maintenance and replacement, resulting in high costs; lead-acid batteries are not environmentally friendly and are difficult to degrade and environmentally friendly after use; Chargin...
