The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example
[0018] Reference Figure 1-8A pile foundation support and tilt correction device for a frame structure building comprises a wall support 1, an insulation wall panel 3 is arranged on the inner side of the wall support 1, and an insulation cavity 4 is arranged inside the wall support 1, a plurality of electrically controlled upper vent valves 12 and a lower vent valve 2 are arranged between the inner side of the wall support 1 and the insulation cavity 4, a plurality of mounting grooves 5 are arranged on the outer side of the wall support 1, and a plurality of photovoltaic support frames 13 are installed inside the mounting grooves, a movable seat 15 is rotatably installed inside the photovoltaic support frame 13, and an adjustment motor 14 is installed inside the movable seat 15, an angle adjustment rod 9 is installed at the bottom end of the output shaft of the adjustment motor 14, a movable support ring 17 is rotatably installed outside the angle adjustment rod 9, a main electric push rod 10 for adjusting the angle is hinged between the movable support ring 17 and the photovoltaic support frame 13, a mounting frame 18 is installed on one side of the angle adjustment rod 9, and a solar cell panel 16 is installed on the outer surface of the mounting frame 18, the solar cell panel 16 is preferably a copper indium gallium selenide thin film solar cell, and an isolation ring 25 is arranged at the outer edge of the photovoltaic support frame 13.
[0019] In the present invention, a heat preservation cavity 4 and an installation groove 5 are arranged in the wall unit of the sun-facing side of the assembled building, a heat-conducting thin wall is arranged between the heat preservation cavity 4 and the installation groove 5, a solar panel 16 is installed inside the installation groove 5, and a composite photovoltaic wall is formed on the sun-facing side of the building by relying on the solar panel 16. The main electric push rod 10 pushes the solar panel 16 out, and the regulating motor 14 drives the solar panel 16 to rotate to follow the direction of the sun to extend the illumination time and increase the illumination coverage area. The temperature of the solar panel 16 rises significantly after the photothermal conversion under the action of solar radiation, and then part of the heat is transferred to the photovoltaic support frame 13, and then the photovoltaic support frame 13 is installed. The area of the groove 5 forms a warm area, and the heat is transferred to the insulation cavity 4 through the thin wall. The air inside the insulation cavity 4 forms an upward flow due to the heating. When the temperature inside the insulation cavity 4 is higher than the indoor temperature, the upper ventilation valve 12 and the lower ventilation valve 2 are opened, and the temperature difference in the air forms a chimney effect inside the insulation cavity 4, so that the air inside the insulation cavity 4 and the indoor air form a circulation, and then in winter without relying on other heat sources, the indoor temperature is maintained to meet the heating needs, thereby reducing the heating energy consumption of the building. At night, the solar cell panel 16 is retracted to seal the opening of the photovoltaic support frame 13, forming a multi-layer cavity isolation structure on the outside of the wall to enhance the thermal insulation effect of the wall.
[0020] As a further solution in the present invention, at least two water tanks 20 made of insulation material are arranged at the bottom of the wall bracket 1, the water tanks 20 are buried under the ground, and a solar water heating component is arranged inside the photovoltaic support frame 13, and the solar water heating component and the water tank 20 are connected by a pipeline. In the present invention, a water tank 20 and a solar water heating component are also arranged. Under the action of solar radiation, the sunny side of the wall heats the water and stores it in the water tank 20 and the solar water heating component. In summer, the water tank 20 is connected to the domestic water in the building, and the hot water consumed in daily life can be used, and the hot water in the solar water heating component can be gradually replaced by cold water, thereby generating The utilized water is concentrated at night. At this time, the solar water heating component contains cold water, which can cool the wall surface. In winter, the water in the water tank 20 and the solar water heating component circulates. At this time, the water in the water tank 20 and the solar water heating component contains warm water. At night, the solar panel 16 is retracted into the wall to form a closed structure. The warm water in the solar water heating component slowly dissipates heat, continuously heats the inside of the insulation chamber 4, and flows in the self-circulation formed by the water tank 20 and the solar water heating component. The cold water drops and the hot water rises, and then the indoor temperature is continuously maintained by the water temperature at night. When the water temperature in the solar water heating component drops, the heating energy consumption of the building at night is effectively saved.
[0021] As a further solution in the present invention, the solar water heating component includes a water storage chamber 8 arranged inside the photovoltaic support frame 13, and a vacuum solar collector tube 19 arranged in the middle of the mounting frame 18. An insulating hose 21 is installed between the water storage chamber 8 and the two ends of the vacuum solar collector tube 19. A water supply pipe 22 and a drainage solenoid valve 23 are also arranged around the water storage chamber 8. The drainage solenoid valve 23 is connected to multiple water tanks 20 through a three-way valve. In the present invention, an internal circulation is formed between the multiple water storage chambers 8 and the water tank 20. The vacuum solar collector tube 19 receives solar radiation and continuously heats the water in the water storage chamber 8. The hot water is stored in the water tank 20 through the connection with the water tank 20. In winter, the warm water stored in the internal circulation provides a heat source for the building at night, and in summer, it provides domestic hot water for the building, further reducing the energy consumption in the building.
[0022] As a further solution in the present invention, the outer surface of the mounting frame 18 is provided with a U-shaped cavity whose inner wall is a reflective mirror, and the vacuum solar collector tube 19 is installed inside the U-shaped cavity, and an insulating glass 26 is installed on the outer side of the U-shaped cavity. The insulating glass 26 is flush with the surface of the solar panel 16 to maintain the flatness of the outer wall surface of the wall, and at the same time, the isolation effect of the outer surface of the wall is enhanced, and heat loss is avoided when the mounting frame 18 and the solar panel 16 close the photovoltaic support frame 13 at night.
[0023] As a further solution in the present invention, a vertically arranged heat-conducting partition 6 is installed inside the insulation chamber 4, and a plurality of connecting rods 7 are installed on one side of the heat-conducting partition 6. The connecting rods 7 penetrate the wall between the insulation chamber 4 and the installation groove 5. Through the arrangement of the heat-conducting partition 6 and the connecting rods 7, the heat transfer between the insulation chamber 4 and the installation groove 5 is effectively enhanced, the heat convection between the indoor air and the air inside the insulation chamber 4 is accelerated, and the indoor temperature is maintained stable.
[0024] As a further solution in the present invention, a multi-layer surrounding flowing water coil 11 is arranged at the top of the inner part of the insulation chamber 4, and the top of the heat-conducting baffle 6 is arranged inside the flowing water coil 11. In the present invention, at night in winter, the flowing water coil 11 is connected to the water tank 20, and the circulating warm water is used at night to further enhance the heating and insulation effect of the room and save heating energy. In summer, one of the water tanks 20 is disconnected from the solar water heating component and connected to the flowing water coil 11. Circulating cold water is passed into the flowing water coil 11, and then a cold air mass is formed at the upper end of the heat-conducting baffle 6. The cold air mass settles inside the insulation chamber 4, stirring the heat convection between the insulation chamber 4 and the indoor air, thereby cooling the room. Example
[0025] Reference Figure 1-9 , a frame structure building pile foundation support tilt correction device, the heat conduction partition 6 includes a fixed partition 601 located at the top and bottom of the insulation chamber 4, and a movable partition 602 located in the middle of the insulation chamber 4, and auxiliary electric push rods 606 are installed between the four corners of the movable partition 602 and the wall bracket 1, and a plurality of one-way valves 605 are also arranged between the insulation chamber 4 and the installation groove 5. The flow direction of the one-way valve 605 is from the installation groove 5 to the insulation chamber 4. In this embodiment, when the wall surface is in a solar radiation environment, the auxiliary electric push rod 606 drives the movable partition 602 to move in the insulation chamber 4. The temperature chamber 4 reciprocates inside, and when the movable partition 602 moves toward the indoor direction, the one-way valve 605 is in a circulation state, and the outdoor air is sucked in through the gap between the installation groove 5 and the photovoltaic support frame 13. At this time, the photovoltaic support frame 13 and the photovoltaic components on its surface are under solar radiation, and the inhaled air is heated. When the movable partition 602 moves in the opposite direction, the inhaled hot air is pressed into the room through the upper ventilation valve 12 and the lower ventilation valve 2. Through the forced flow of indoor and outdoor air, the room is heated and the temperature around the solar cell panel 16 is reduced.
[0026] A second water storage chamber 603 is provided on one side of the movable partition 602 close to the installation groove 5, and a plurality of second thermal insulation hoses 604 are installed on one side of the second water storage chamber 603. A liquid replenishing solenoid valve 24 is provided between the outer side of the water storage chamber 8 and the thermal insulation hose 604. Through the second thermal insulation hose 604 and the liquid replenishing solenoid valve 24, the movable partition 602 is incorporated into the internal circulation formed between the water storage chamber 8 and the water tank 20. In the winter lighting environment, the hot water in the movable partition 602 forms a large-area heat radiator, which increases the temperature inside the thermal insulation chamber 4 and the indoor temperature. At night, the photovoltaic support frame 13 is closed, causing the installation groove 5 to be in a closed environment, and the movable partition 602 is in a stationary state. The movable partition 602 continuously and stably dissipates heat, increases the heat exchange area, further reduces the heating energy consumption of the building, and achieves near-zero energy consumption for heating in winter.
[0027] When in use, the sun-facing side of the building relies on the solar panel 16 to form a composite photovoltaic wall, the main electric push rod 10 pushes the solar panel 16 out, and the adjustment motor 14 drives the solar panel 16 to rotate and follow the direction of the sun to extend the illumination time and increase the illumination coverage area, and the temperature of the solar panel 16 rises significantly after the photothermal conversion under the action of solar radiation, and then part of the heat is transferred to the photovoltaic support frame 13, thereby forming a warm area in the area of the installation groove 5, and the heat is transferred to the insulation cavity 4 through the thin wall. The air inside the insulation cavity 4 forms an upflow due to being heated. When the temperature inside the insulation cavity 4 is higher than the indoor temperature, the upper ventilation valve 12 and the lower ventilation valve 2 are opened, and the temperature difference in the air forms a chimney effect inside the insulation cavity 4, so that the air inside the insulation cavity 4 and the indoor air form a circulation, and then in winter without relying on other heat sources, the indoor temperature is maintained to meet the heating demand, reducing the heating energy consumption of the building, and at night, the solar panel 16 is retracted to seal the opening of the photovoltaic support frame 13, forming a multi-layer cavity isolation structure on the outside of the wall, and enhancing the thermal insulation effect of the wall.
