Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic power generation, and specifically refers to a high-efficiency energy-saving device for low-energy consumption buildings. Background Art

[0002] Low-energy buildings refer to buildings that do not use or use as little primary energy as possible, and use renewable energy. Low-energy buildings often use photovoltaic power generation to supplement the power of the building. Usually, single-family buildings will place photovoltaic panels on the roof with better lighting. However, for buildings with more residents, the roof area is limited and cannot meet the needs of all residents. In this case, photovoltaic panels will be hung on the south-facing wall. The direction of the sun will change continuously throughout the day, and the power generation efficiency is highest when sunlight directly shines on the photovoltaic panels. Therefore, in order to improve the power generation efficiency, there are some photovoltaic power generation devices with tracking functions on the market, which control the photovoltaic panels to track the light angle throughout the day to improve the power generation efficiency. However, these devices are usually designed for use on flat ground and are not suitable for hanging on the side walls of buildings.

[0031] like Figure 4 and Figure 5 As shown, the pressure mechanism 4 includes a cylinder 401, a heating module 402, an extension plate 403, a secondary photovoltaic panel 404 and a cooling module 405.

When the secondary photovoltaic panel 404 is exposed to stronger light, the heating power of the heating module 402 is greater, and the compressed gas pressure in the cylinder 401 is greater. Preferably, the height of the secondary photovoltaic panel 404 is less than the height of the side wall of the cylinder 401.

[0032] When used specifically, take the use in the northern hemisphere as an example for explanation. The present invention is hung on the south exterior wall of the building or placed on the roof facing south through external equipment, so that when the main photovoltaic panel 101 is in the middle, the light-receiving surface faces south. In the early morning of a day, the sun rises and the cooling module 405 is started. The cooling module 405 cools down the cylinder 401 respectively. The sunlight starts to shine from the southeast direction. The secondary photovoltaic panel 404 of the pressure mechanism 4 on the east side is illuminated by the sunlight. The secondary photovoltaic panel 404 of the pressure mechanism 4 on the opposite side of the sun's deflection direction is blocked by the cylinder 401 and the main photovoltaic panel 101 and receives less sunlight. The secondary photovoltaic panel 404 of the pressure mechanism 4 on the west side 4 is exposed to a small amount of sunlight, and the heating power of the heating module 402 on the east side is greater than that of the heating module 402 on the west side. With the cooling of the cooling module 405, the pressure in the cylinder 401 on the east side is much greater than that in the cylinder 401 on the west side. The gas in the cylinder 401 on the east side pushes the piston 302 on the east side to push the arc rod 301 to the sliding limit, and the extension rod 303 drives the active gear 304 to rotate, and the active gear 304 drives the passive gear 105 to rotate in the opposite direction, turning the main photovoltaic panel 101 to the direction of direct sunlight. During the sliding process of the arc rod 301, the positioning buckle 306 is inserted into the slot 213, so that the main photovoltaic panel 101 The rotation remains stable, and the pressure in the two cylinders 401 needs to reach a certain difference before the arc rod 301 moves. When the pressure difference between the two cylinders 401 is sufficient to push the piston 302 to push the positioning buckle 306 out of the current slot 213, the arc rod 301 slides toward the cylinder 401 with lower pressure in the cylinder, and inserts the positioning buckle 306 into the next slot 213. At this time, the sealing area on the east side of the arc rod 301 becomes larger, and the air pressure in the cylinder 401 on the east side becomes smaller, and the sealing area on the west side of the arc rod 301 becomes smaller, and the air pressure in the cylinder 401 on the west side becomes larger. The pressure difference between the two cylinders 401 is temporarily small, and the positioning buckle 306 and the slot 213 are matched. The main photovoltaic panel 101 is temporarily fixed at the current angle; as time goes by, the secondary photovoltaic panel 404 on the west side gradually begins to be exposed to sunlight, the heating module 402 on the west side starts to work, the pressure difference between the cylinders 401 on the east and west sides gradually decreases, the gas in the cylinder 401 on the west side pushes the arc rod 301 in the opposite direction, and the main photovoltaic panel 101 rotates in the opposite direction; at noon, both secondary photovoltaic panels 404 are directly exposed to the sun, and the two secondary photovoltaic panels 404 are exposed to the same amount of sunlight, and the temperature in the cylinder 401 is gradually balanced with the cooling module 405, the pressure in the two cylinders 401 is close to the same, and the main photovoltaic panel 101 faces the middle;In the afternoon and evening, the secondary photovoltaic panel 404 on the west side gradually receives more sunlight, and the heating power of the heating module 402 on the west side gradually exceeds the heating power of the heating module 402 on the east side. With the cooling of the cooling module 405, the pressure in the cylinder 401 on the west side exceeds the pressure in the cylinder 401 on the east side. As time goes by, the pressure changes with the angle of sunlight, and the pressure difference gradually increases. The main photovoltaic panel 101 rotates with the sun gradually setting in the west; after sunset, the cooling module 405 can be turned off, and the pressure of the gas in the cylinder 401 is balanced after natural cooling overnight, and the above principle continues to work in the early morning of the next day. ;
