DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 to Figure 4 As shown, a solar thermal energy storage device comprises a base 1, a concentrating platform 2 is fixedly connected to the top of the base 1, a group of fixing rods 3 are fixedly connected to the outer circumference of the base 1, a heating box 4 is fixedly connected to the top of the fixing rods 3, and a heat storage mechanism 5 is provided on the top of the base 1;

[0025] The heat storage mechanism 5 includes a water tank 50 disposed on the top of the heating box 4. A temperature sensor 12 is fixedly connected to the bottom of the water tank 50, and the temperature sensor 12 is electrically connected to the controller 13. The temperature sensor 12 detects the temperature inside the water tank 50 in real time. When the temperature reaches the temperature that can open the solenoid valve 39, the controller 13 controls the solenoid valve 39 to open. A group of support rods 14 are fixedly connected to the top of the heating box 4, and the tops of the support rods 14 are fixedly connected to the water tank 50 to strengthen the support of the water tank 50. A group of connecting pipes 51 are fixedly connected to the bottom of the water tank 50 in a circumferential direction, and the bottom ends of the connecting pipes 51 are connected to the heating box 4. A water cylinder 52 is fixedly connected to the bottom of the water tank 50, and the bottom end of the water cylinder 52 extends to the bottom of the heating box 4. The inside of the water cylinder 52 is fixedly connected with a solenoid valve 7, and the top of the base 1 is fixedly connected with a controller 13. When the drain pipe 54 discharges the hot water inside the water storage tank 50, the solenoid valve 7 is closed, and water is added to the heating box 4 through the water inlet pipe 53. Clean water flows into the water storage tank 50 until it is filled. At this time, cold water can be prevented from entering the water cylinder 52, ensuring that the cold water inside the water storage tank 50 and the heating box 4 can be heated during heat storage, and preventing cold water from directly entering the water cylinder 52, resulting in the cold water at the bottom of the water cylinder 52 not being heated. The water inlet pipe 53 is fixedly connected to one side of the bottom end of the heating box 4, and the drain pipe 54 is fixedly connected to the bottom end of the water cylinder 52. The end of the water inlet pipe 53 away from the heating box 4 is installed with a solenoid valve 2 8, and the end of the drain pipe 54 away from the water cylinder 52 is installed with a solenoid valve 3 9. When storing heat, the solenoid valve 2 8 and the solenoid valve 3 9 are closed. When draining, the solenoid valve 3 9 is automatically opened, and when water is in, the solenoid valve 2 8 is automatically opened. A reflector 55 is fixedly connected to the inner side of the focusing table 2, and the diameter of the top of the reflector 55 is larger than the diameter of the bottom. A heating surface 56 is provided on the outer side of the heating box 4. The heating surface 56 is wavy, and the diameter of the top of the heating surface 56 is larger than the diameter of the bottom. A water level sensor 10 is fixedly connected to the top of the water tank 50, and a water level sensor 2 11 is fixedly connected to the bottom of the water tank 50. The water level sensor 2 11 detects the drainage. When there is no water in the water tank 50, the solenoid valve 2 8 automatically opens to add water. The water level sensor 10 detects the water level when adding water. When the water tank 50 is full of water, the solenoid valve 2 8 automatically closes.

[0026] During operation, the design of the shape features of the reflector 55 and the heating surface 56 enables the reflector 55 to reflect more sunlight on the heating surface 56, and the wavy design of the heating surface 56 increases the lighting area of ​​the heating surface 56, which is beneficial for the heating surface 56 to receive more sunlight, thereby greatly improving the heating capacity and efficiency. The heating box 4 and the water storage tank 50 are filled with clean water through the water inlet pipe 53, and the clean water inside the heating box 4 is heated by sunlight. Due to the increase in water temperature and low density, the hot water will flow upward through the connecting pipe 51 to the water storage tank 50, and the clean water with low temperature in the water storage tank 50 will flow downward into the heating box 4 due to its high density, thereby continuously heating the clean water inside the heating box 4, thereby improving the heat storage effect. Furthermore, this structure enables more sunlight to be reflected on the heating surface 56, and by increasing the lighting area of ​​the heating surface 56, the waste of reflected sunlight is reduced, thereby greatly improving the heat storage speed, and facilitating faster heat storage work.

[0027] A dust removal mechanism 6 is provided on the top of the base 1, and an inner cavity 61 is opened inside the dust removal mechanism 6. A motor 62 is fixedly connected to the bottom end of the inner cavity 61, and a rotating shaft 63 is fixedly connected to the output end of the motor 62. The top of the rotating shaft 63 extends to the top of the base 1. L-shaped rods 64 are fixedly connected to both sides of the top of the rotating shaft 63. Dust removal brushes 65 are fixedly connected to the ends of the L-shaped rods 64. The bristles of the dust removal brush 65 are in contact with the reflector 55. The dust removal brush 65 sweeps the dust on the surface of the reflector 55.

[0028] During operation, when a large amount of dust and other debris adheres to the surface of the reflector 55, the power of the motor 62 is turned on, and the output end of the motor 62 drives the rotating shaft 63 to rotate, the rotating shaft 63 drives the L-shaped rod 64 to rotate, and the L-shaped rod 64 drives the dust removal brush 65 to rotate. The dust removal brush 65 cleans the dust on the surface of the reflector 55 to avoid excessive dust affecting the reflector 55's reflection of sunlight, thereby reducing the heat storage effect.

[0029] Working principle: The design of the shape characteristics of the reflector 55 and the heating surface 56 enables the reflector 55 to reflect more sunlight on the heating surface 56, and the wavy design of the heating surface 56 increases the lighting area of ​​the heating surface 56, which is beneficial for the heating surface 56 to receive more sunlight, greatly improving the heating capacity and efficiency, and the heating box 4 and the water storage tank 50 are filled with clean water through the water inlet pipe 53, and the clean water inside the heating box 4 is heated by sunlight. Due to the increase in water temperature and low density, the hot water will flow upward through the connecting pipe 51 to the water storage tank 50, and the clean water with low temperature in the water storage tank 50 will flow downward into the heating box 4 due to its high density, thereby continuously heating the clean water inside the heating box 4, thereby improving the heat storage effect, and then this structure enables more sunlight to be reflected on the heating surface 56, and by increasing the lighting area of ​​the heating surface 56, the waste of reflected sunlight is reduced, greatly improving the heat storage speed, and facilitating faster heat storage work.

[0030] When a large amount of dust and other debris adheres to the surface of the reflector 55, the power of the motor 62 is turned on, and the output end of the motor 62 drives the rotating shaft 63 to rotate, the rotating shaft 63 drives the L-shaped rod 64 to rotate, and the L-shaped rod 64 drives the dust removal brush 65 to rotate. The dust removal brush 65 cleans the dust on the surface of the reflector 55 to avoid excessive dust affecting the reflector 55's reflection of sunlight, thereby reducing the heat storage effect.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
