[0002] With the rapid development of the global economy, the demand for energy in various countries is also growing. Many energy sources are non-renewable resources, such as coal and oil. Therefore, some countries have even gone to war because of the competition for energy. In addition, the continuous demand for energy will also seriously damage the environment. For example, the combustion of coal and oil will produce carbon monoxide, sulfur dioxide, carbon dioxide and other gases. Therefore, many countries have begun to develop some clean energy, which on the one hand guarantees the demand for energy and on the other hand avoids environmental pollution problems. Nowadays, the use of water potential energy, wind energy and solar energy to generate electricity and use solar energy for heating has been widely used by people.

[0045] It can be known that the focusing lens 230 and the heat exchange tube 100 can be one, two or more than three, and the specific number can be set according to actual needs.

[0046] It is worth noting that the heat exchange tube 100 can be connected to the heating shell 220 in a detachable manner through a fixing part, such as a stainless steel sheet. The stainless steel sheet can be connected to the heating shell 220 by screws or threads. At the same time, corresponding fixing slots are provided on the stainless steel sheet. The heat exchange tube 100 can be inserted into the corresponding fixing slots to achieve a fixed connection. In addition, other fixing parts or welding methods can be used to achieve a fixed connection. The specific fixing method belongs to the conventional technical means of those skilled in the art and will not be described in detail here.

[0047] Working principle: The liquid to be heated enters the heating shell 220 from the first input end. When exposed to sunlight, the focusing mirror 230 can focus the light and concentrate it on the corresponding heat absorption surface 121. The heat exchange tube 100 will transfer the heat from the heat absorption part 120 to the heat transfer tube and the heat release part 110 in sequence. The heat release part 110 will release the heat to the liquid to be tested. When the liquid to be tested reaches the evaporation temperature after being heated, it will turn into steam and be output from the first output end.

[0048] It can be known that in some embodiments of the present disclosure, the liquid to be heated is seawater, and the seawater enters the heating shell 220 from the first input end. When exposed to sunlight, the focusing mirror 230 can focus the light and concentrate it on the corresponding heat absorption surface 121. The heat exchange tube 100 will transfer the heat from the heat absorption part 120 to the heat transfer tube and the heat release part 110 in sequence. The heat release part 110 will release the heat to the liquid to be tested. When the seawater reaches the evaporation temperature after being heated, it will turn into water vapor and be output from the first output end. At the same time, the salt in the seawater will remain at the bottom of the heating shell 220. When it accumulates to a certain amount, it can be discharged from the solid discharge end.

[0049] It can be known that valves can be set at the solid discharge end, the first output end and the first input end to control the opening and closing of the corresponding ports, thereby controlling the input of seawater, the discharge of salt and the discharge of water vapor.

In accordance with the aforementioned structure, the angle between the extension direction of the first pipe 131 and the heat absorbing surface 121 is acute, the extension direction of the second pipe 132 is perpendicular to the heat absorbing surface 121, and the angle between the extension direction of the third pipe 133 and the heat absorbing surface 121 is acute. The first pipe 131, the second pipe 132, and the third pipe 133 are located in the same plane, and the first pipe 131 and the third pipe 133 are located on the same side of the second pipe 132. The first pipe 131 extends obliquely upward from the first end of the second pipe 132, and the third pipe 133 extends obliquely downward from the second end of the second pipe 132.

In combination with the dual-axis drive assembly 250, the focusing mirror can be adjusted as the position of the sun changes, thereby ensuring that the focusing mirror 230 is always facing the sun, that is, the sunlight can always be directed perpendicular to the plane of the focusing mirror 230.

[0056] Reference Figure 4 and Figure 5 In some embodiments of the present disclosure, a solar position sensor 260 is further included around the focusing mirror 230. The solar position sensor 260 can be used to automatically detect the sun's position in real time, thereby controlling the dual-axis drive assembly 250 and swinging the fixed portion 240 so that the focusing mirror 230 always faces the sun.

[0057] It can be known that in some embodiments of the present disclosure, a conventional control module is also included, and the control module is electrically connected to the dual-axis drive component 250 and the solar position sensor 260 respectively.

[0062] Working principle: Seawater enters the collector 200 from the first input port. When exposed to sunlight, the collector 200 collects solar energy and heats the seawater. When the seawater reaches its evaporation temperature, it turns into water vapor and is output from the first output port. At the same time, the salt in the seawater remains in the collector 200.

The third output end is connected to the second input end, and the third input end is connected to the first output end.

[0084] It can be seen that the third output terminal and the second input terminal, as well as the third input terminal and the first output terminal, are connected via pipes and valves. The valves can control the corresponding pipes to connect or disconnect them. The first tank 500 can be used to store water vapor. When a preset amount is reached, the water vapor in the first tank 500 can be input into the steam engine 300, thereby improving the efficiency of converting steam energy into mechanical energy and also improving power generation efficiency. When multiple collectors 200 are used, the amount of water vapor output by each collector 200 is limited. If it is directly input into the steam engine 300, it may not meet the high-power power generation demand. Therefore, the first tank 500 can be provided for storage to increase the capacity of the instantaneous water vapor input to the steam engine 300, thereby improving power generation efficiency. It should be noted that when the first tank 500 is not used, power generation can still be achieved, but the generated power is smaller and can only meet small power generation needs, such as the electricity needs of a single residential building.

[0085] It can be known that in order to reduce the amount of water vapor condensation, the first tank body 500 can be provided with corresponding insulation materials, which can extend or reduce the speed of water vapor heat release to ensure that a stable amount of water vapor can be output, thereby improving the stability and reliability of power generation.

The second tank body 600 can be used to store water vapor that has passed through the steam engine 300. After the water vapor passes through the steam engine 300, it may not be directly cooled into liquid and flow out, and part of it is still output as water vapor. Using the second tank body 600, water vapor or water can be stored, and then when fresh water is needed, the fresh water can be output from the fourth output end.

[0091] In some embodiments of the present disclosure, the steam engine 300 is a Stirling engine or a steam turbine. Depending on the needs, the Stirling engine or steam turbine can be selected. When the power generation demand is large, a Stirling engine can be used, while when the power generation demand is small, a steam turbine can be used. For example, when the electricity demand of residential buildings in an area needs to be met, a Stirling engine can be used. Meanwhile, the generator 400 directly outputs current to the grid. When the electricity demand of only one residential building needs to be met, a steam turbine can be used, and the generator 400 can directly transmit electricity to the residents' homes.

[0092] According to the embodiment of the present disclosure, the solar power generation device that integrates power generation and fresh water production can achieve at least the following effects through such configuration: the solar energy can be effectively collected by the collector 200, and the solar energy can be used to heat seawater, so that the seawater is converted into water vapor and input into the steam engine 300. The steam engine 300 can convert the energy of the water vapor into mechanical energy, and then the steam engine 300 is used to drive the generator 400 to generate electricity, effectively improving the photoelectric conversion rate; and the water vapor can be cooled after passing through the steam engine 300 and converted into fresh water for use. In combination with the collector 200, the steam engine 300 and the generator 400, it can not only be promoted and applied on a large scale, but also can simultaneously achieve the purposes of power generation and fresh water production, effectively reducing the cost of solar power generation.

[0094] The fifth output end and the second output end, the seventh input end and the sixth output end, the eighth input end and the seventh output end, the eighth output end and the sixth input end, and the ninth output end and the second input end are all connected through pipelines. The eighth input end and the eighth output end are connected to the same first cavity, and the ninth input end and the ninth output end are connected to the same second cavity, that is, the heated heat transfer oil is input into the first cavity, and the liquid to be heated enters the second cavity. In conjunction with the heat exchange element in the heat exchanger 800, the heat of the heat transfer oil can be transferred to the liquid to be heated, so that the liquid to be heated evaporates and becomes steam, and then is transported to the steam engine 300 through the pipeline, so that the energy of the steam is converted into mechanical energy to drive the generator 400 to generate electricity.

[0095] Working principle: When there is sunlight, the liquid to be heated can enter the first heat collector 270 from the fifth input end. When the sunlight is irradiated, the first heat collector 270 can collect solar energy and heat the seawater. When the seawater reaches the evaporation temperature after being heated, it will become steam and be output from the fifth output end. The steam is input into the steam engine 300. The steam engine 300 can convert the energy of the steam into mechanical energy. Then the steam engine 300 is used to drive the generator 400 to generate electricity. The steam after passing through the steam engine 300 will be output through the second output end. At the same time, when the first heat collector 270 collects solar energy, the second heat collector 280 will also collect solar energy to heat the thermal oil to store heat energy. After passing through the second heat collector 280 The heated heat transfer oil will be input into the third tank body 700 for storage. When there is no sunlight, such as at night or on cloudy days, the heat transfer oil in the third tank body 700 will be input into the heat exchanger 800. At the same time, the liquid to be heated will also be input into the heat exchanger 800 at the same time. Through the heat exchanger 800, the liquid to be heated will evaporate into steam, and then be transported to the steam engine 300 through a pipeline to realize the conversion of steam energy into mechanical energy to drive the generator 400 to generate electricity. The steam after passing through the steam engine 300 will be output through the second output end.

[0096] It is worth noting that, referring to Figure 11 The liquid to be tested can be seawater. After being heated and evaporated by the first heat collector 270 and the heat exchanger 800, salt will be generated. Therefore, a solid discharge end can be set at the bottom of the first heat collector 270 and the heat exchanger 800. By setting a valve and utilizing gravity, salt discharge can be achieved. At the same time, seawater will become fresh water after evaporation. Therefore, the steam output by the steam engine 300 can be collected and condensed in conjunction with the condenser. The fresh water can be stored and used as domestic water. The purpose of generating electricity and making fresh water can be achieved simultaneously, effectively reducing the cost of solar power generation.

[0097] In addition, the liquid to be tested may also be other liquids, such as ordinary neutral water.

After the steam passes through the steam engine 300, it may not be directly cooled into liquid and flow out, and part of it is still output as steam. Using the second tank body 600, steam or liquid can be stored.

[0124] In some embodiments of the present disclosure, the steam engine 300 is a Stirling engine or a steam turbine. Depending on the needs, the Stirling engine or steam turbine can be selected. When the power generation demand is large, a Stirling engine can be used, while when the power generation demand is small, a steam turbine can be used. For example, when the electricity demand of residential buildings in an area needs to be met, a Stirling engine can be used. Meanwhile, the generator 400 directly outputs current to the grid. When the electricity demand of only one residential building needs to be met, a steam turbine can be used, and the generator 400 can directly transmit electricity to the residents' homes.

[0125] According to the embodiment of the present disclosure, the solar thermal power generation system that can generate electricity continuously can achieve at least the following effects by being set up in this way: the first collector 270 can effectively collect solar energy, and can use solar energy to heat the liquid to be heated, so that the liquid to be heated becomes steam and is input into the steam engine 300, and the steam engine 300 can convert the energy of the steam into mechanical energy, and then use the steam engine 300 to drive the generator 400, so as to realize power generation, and effectively improve the photoelectric conversion rate; in addition, in conjunction with the second collector 280 and the third tank body 700, solar energy can be used to heat and store the thermal oil in advance. When there is no sun, the heat exchanger 800 can be used to heat the liquid to be heated with the heat energy of the heated thermal oil, so that the liquid to be heated becomes steam and is input into the steam engine 300, thereby achieving the purpose of being able to generate electricity continuously for 24 hours, and effectively improving the reliability of power generation.

[0126] The above description is merely a preferred embodiment of the present disclosure. The present disclosure is not limited to the aforementioned embodiments. As long as the technical effects of the present disclosure are achieved by the same means, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure. Various modifications and variations of the technical solutions and / or implementation methods may be made within the scope of protection of the present disclosure.
