Description

Technical Field

[0001] This application relates to the field of photovoltaic energy storage, and more specifically, to a building-integrated photovoltaic energy storage device. Background Technology

[0002] Building-integrated photovoltaics (BIPV) is a technology that combines solar power generation with buildings. It converts solar energy into electricity by installing photovoltaic panels on buildings, enabling buildings to be self-sufficient or reducing reliance on the traditional power grid. BIPV technology not only helps reduce energy consumption and carbon emissions but also provides buildings with green, renewable energy. This system can store electricity generated by photovoltaic panels when it exceeds the building's immediate consumption and release it when needed. The application of this system not only solves the energy storage and dispatching problems of BIPV technology but also improves the energy efficiency and stability of photovoltaic buildings. BIPV energy storage devices, as a novel technology, can effectively solve the energy storage and dispatching problems of BIPV technology, improving energy efficiency and stability.

[0003] Patent document CN117914240B discloses a building-integrated photovoltaic (BIPV) energy storage device. This invention discloses a building-integrated photovoltaic energy storage device in the field of photovoltaic energy storage technology, including a regulating component, a negative pressure component, a building body, two sets of photovoltaic modules, and a temperature monitoring component. The building body includes an inverted V-shaped roof, and each photovoltaic module includes a support frame and a solar panel. The temperature monitoring component monitors the temperature at the solar panels. When the temperature reaches a first preset value, the two solar panels form a V-shape, which drives the negative pressure component to generate negative pressure, and transmits it to one side of the roof through an air amplifier, increasing the air circulation speed on the roof.

[0004] The aforementioned application document uses a negative pressure component and an air amplifier to increase the air circulation speed on the roof. However, the triggering of the negative pressure component after the two solar panels form a V-shape is a one-time event. When the temperature continues to rise, it is not convenient to continuously increase the air circulation speed on the roof by triggering the negative pressure component multiple times, thus failing to achieve a better cooling effect.

[0019] (3) This application removes dust from the photovoltaic panel body by setting up a cleaning component. The lowering of the photovoltaic panel body after it is raised can drive the cleaning component to sweep on the photovoltaic panel body, which facilitates the removal of dust from the photovoltaic panel body.

[0036] Example 1, see Figures 1-8This embodiment provides a building-integrated photovoltaic (BIPV) energy storage device, including a building roof 1. A support frame 2 is fixedly installed on the roof 1. The support frame 2 specifically includes a mounting plate and two T-shaped brackets. The mounting plate is bolted to the roof 1. A photovoltaic panel body 3 is rotatably connected to the inner surface of the support frame 2. There are two photovoltaic panel bodies 3. Two electric push rods 4 are hinged to the bottom of the photovoltaic panel bodies 3. The electric push rods 4 are hinged to the bottom of the inner surface of the support frame 2. A partition plate 401 is fixedly connected to the back of the support frame 2. Trigger elements 5 are provided on the left and right sides of the partition plate 401. The trigger element 5 includes a chamber 501. The chamber 501 includes a spherical cavity and a cylindrical channel. 01 is fixedly connected to the partition 401. There are two chambers 501, which are respectively set on the left and right sides of the partition 401. A first piston rod 502 is slidably connected to the inner surface of the chamber 501. The piston in the first piston rod 502 is set in the cylindrical channel in the chamber 501. An expansion fluid is provided on the inner surface of the chamber 501 and is set in the spherical cavity in the chamber 501. Mounting plates 503 are fixedly connected to the left and right sides of the partition 401. A pressure sensor 504 is fixedly connected below the mounting plate 503. There are two mounting plates 503 and pressure sensors 504. The pressure sensor 504 is electrically connected to the electric push rod 4. The pressure sensor 504 can convert the pressure signal into an electrical signal to control the pressure. The extension and retraction of the electric push rod 4 is controlled by two pressure sensors 504 in an interleaved manner. Specifically, the pressure sensor 504 on the right controls the electric push rod 4 located below the photovoltaic panel body 3 on the left. Two vent pipes 402 are fixedly connected to the top of the photovoltaic panel body 3. These two vent pipes are connected by a pipeline and a flexible hose, and are interconnected. An air amplifier 403 is fixedly installed above each vent pipe 402. A pressure component 6 is located on the front of each vent pipe 402. Both photovoltaic panel bodies 3 are equipped with pressure components 6, arranged symmetrically on the left and right sides. Each pressure component 6 includes an air chamber 601. The air in the air chamber 601 of a single pressure component 6... The body can enter two ventilation pipes 402. The air chamber 601 is fixedly connected to the front of the photovoltaic panel body 3. The air chamber 601 and the ventilation pipe 402 are fixedly connected and interconnected. A second piston rod 602 is slidably connected to the inner surface of the air chamber 601. A top block 603 is fixedly connected to the left end of the second piston rod 602. The top block 603 is shaped like a frustum. A first spring 604 is elastically connected between the top block 603 and the air chamber 601. The first spring 604 is used to reset the top block 603 and the second piston rod 602. The pneumatic component 6 also includes an arc plate 605. The arc plate 605 is fixedly connected to the outer surface of the support frame 2. A protrusion 606 is fixedly connected to the outer surface of the arc plate 605. The protrusion 606 is semi-circular in shape and there are four of them.Spraying components 7 for cooling the photovoltaic panel body 3 are installed on both the left and right sides of the photovoltaic panel body 3. Two sets of spraying components 7 are symmetrically arranged on the two photovoltaic panel bodies 3. A cleaning component 8 for cleaning the photovoltaic panel body 3 is installed on top of the photovoltaic panel body 3. Two sets of cleaning components 8 are symmetrically arranged on the two photovoltaic panel bodies 3.

[0037] In practical use, the aforementioned device absorbs solar energy through the photovoltaic panel body 3. When the sun rises in the east, it shines on the right-side chamber 501, causing the chamber 501 to heat up and its internal expansion fluid to expand. This expansion fluid in turn pushes the first piston rod 502 upward within the chamber 501. The rise of the first piston rod 502 actuates the pressure sensor 504, pressurizing it. The pressure sensor 504 converts the pressure signal into an electrical signal, controlling the extension and retraction of the electric push rod 4. At this time, the pressure sensor 504 on the right side controls the electric push rod 4 below the left-side photovoltaic panel body 3 to extend. The extension of the electric push rod 4 causes the left-side photovoltaic panel body 3 to rise. At this time, both photovoltaic panel bodies 3 will tilt to the right to face the sun. In the afternoon, the partition 401 will block the right-side chamber 501, causing the chamber 501 to cool down. This causes the left-side photovoltaic panel body 3 to lower down. At this time, the left-side chamber 501 is heated by sunlight, causing the right-side photovoltaic panel body 3 to rise, thus always facing the sun. When the photovoltaic panel body 3 is raised, the top block 603 slides upward on the outer surface of the arc plate 605. When the top block 603 moves to the protrusion 606, the protrusion 606 pushes the top block 603 away from the arc plate 605. At this time, the protrusion 606 presses the first spring 604 and pushes the second piston rod 602 into the air chamber 601, thereby pushing the gas in the air chamber 601 into the ventilation pipe 402 and then ejecting it from the air amplifier 403, thereby increasing the airflow above the photovoltaic panel body 3. It plays a role in cooling. As the temperature continues to rise, the expansion liquid inside the chamber 501 will expand more and more, thereby driving the first piston rod 502 to apply greater pressure to the pressure sensor 504, making the electric push rod 4 extend longer, and the photovoltaic panel body 3 will also be raised higher. During the process of the photovoltaic panel body 3 being raised, the top block 603 will continuously pass over multiple protrusions 606, thereby allowing the gas in the air chamber 601 to enter the vent pipe 402 and then be sprayed out from the air amplifier 403 multiple times, playing a role in cooling multiple times.

[0038] Example 2, see Figures 1-7The spray assembly 7 includes two shaft supports 701, each consisting of an arc-shaped connecting plate and an annular bushing. The shaft supports 701 are fixedly connected to the left side of the photovoltaic panel body 3. A spray pipe 702 is rotatably connected to the inner surface of the shaft supports 701. The rotation between the shaft supports 701 and the spray pipe 702 involves friction. A pipe rotary joint 703 is fixedly connected to the front of the spray pipe 702, used to connect a water pipe to an external water source. A first... The first nozzle 704 is fixedly connected to the left side of the photovoltaic panel body 3, and a support plate 705 is fixedly connected to the top of the support plate 705. A sponge pad 706 is fixedly connected above the support plate 705. Under normal conditions, the first nozzle 704 faces the sponge pad 706, and the sponge pad 706 is in contact with the first nozzle 704. A cooling component 9 is provided behind the spray pipe 702. The spray assembly 7 also includes an arc-shaped rack 707, with teeth on both its inner and outer rings. The arc-shaped rack 707 is fixedly connected to the outer surface of the support frame 2, and a first gear 708 is provided on the outer surface of the arc-shaped rack 707. The first gear 708 is adapted to the arc-shaped rack 707. When the photovoltaic panel body 3 is raised, the first gear 708 can mesh with the arc-shaped rack 707. The first gear 708 has a first rotating shaft 709 that is fixedly connected through its front. The first rotating shaft 709 is rotatably connected to the rear of the photovoltaic panel body 3. A chain 710 is connected between the first rotating shaft 709 and the spray pipe 702. Sprockets for the chain 710 to drive the photovoltaic panel body 3 are provided on the first rotating shaft 709 and the spray pipe 702. The cooling component 9 includes an annular tube 901. The annular pipe 901 is fixedly connected to the outer surface of the silo body 501. A connecting rod is provided between the annular pipe 901 and the silo body 501 for connection. The annular pipe 901 is connected to the spray pipe 702 by pipeline. The annular pipe 901 and the spray pipe 702 are connected by flexible hose. The connection between the annular pipe 901 and the spray pipe 702 is a cross connection, that is, the spray pipe 702 on the right side of the silo body 501 is connected to the spray pipe 702 on the left side of the photovoltaic panel body 3. A second nozzle 902 is fixedly connected below the annular pipe 901.

[0039] In practical use, when the temperature of the chamber 501 rises too high, causing the photovoltaic panel body 3 to rise to its highest point, the rise of the photovoltaic panel body 3 will cause the first gear 708 on the first rotating shaft 709 to contact the arc-shaped rack 707 and roll above it. At this time, the first gear 708 will drive the first rotating shaft 709 to rotate. The rotation of the first rotating shaft 709 will drive the chain 710 to rotate the spray pipe 702 within the shaft support 701. The rotation of the spray pipe 702 will drive the first spray head 704 to move from the sponge pad. 706 moves upward and rotates towards the photovoltaic panel body 3. At this time, by connecting the water pipe to the external water source through the pipe rotary joint 703, the first nozzle 704 can spray water onto the photovoltaic panel body 3 to facilitate cooling. At the same time, the water flow will enter the annular pipe 901 through the hose and then spray out from the second nozzle 902, thereby cooling the chamber 501. This causes the first piston rod 502 inside the chamber 501 to contract, thereby reducing the pressure on the pressure sensor 504, causing the electric push rod 4 to drive the photovoltaic panel body 3 to lower slightly.

[0040] Example 3, see Figures 2-8The cleaning component 8 includes a sliding frame 801, which is U-shaped and fixedly connected to the top of the photovoltaic panel body 3. Two sliding frames 801 are mounted on a single photovoltaic panel body 3. A first brush 802 and a second brush 803 are slidably connected above the sliding frame 801. A reset member 10 is provided on the left side of the first brush 802. A steel wire rope 804 connects the first brush 802 and the second brush 803. A pulley component 805 is provided on the inner surface of the steel wire rope 804. The pulley component 805 includes a U-shaped pulley seat and a pulley body. The pulley component 805 is connected to the photovoltaic panel body 3. The photovoltaic panel body 3 is fixedly connected to the top of the photovoltaic panel body 3. The second brush 803 is closer to the pulley 805. The cleaning assembly 8 also includes a second rotating shaft 806, which is rotatably connected to the rear of the photovoltaic panel body 3. A second gear 807 is provided on the outer surface of the second rotating shaft 806. The second gear 807 is adapted to the arc-shaped rack 707. When the photovoltaic panel body 3 reaches the bottom, the second gear 807 will disengage from the arc-shaped rack 707. A one-way bearing is fixedly connected between the second rotating shaft 806 and the second gear 807. The one-way bearing is used to limit the rotation of the second gear 807 on the second rotating shaft 806. In terms of direction of movement, when the photovoltaic panel body 3 is raised, the second gear 807 rolls on the arc-shaped rack 707, and at this time, the second gear 807 rotates on the second rotating shaft 806. When the photovoltaic panel body 3 is lowered, the second gear 807 rolls on the arc-shaped rack 707, and at this time, the rotation of the second gear 807 will drive the second rotating shaft 806 to rotate. A third gear 808 is fixedly connected to the outer surface of the second rotating shaft 806, and a straight rack 809 meshes above the third gear 808. A slide rail 810 is fixedly connected above the photovoltaic panel body 3. The slide rail 810 has a trapezoidal cross-sectional shape, and the slide rail 810 slides upwards. A sliding seat 811 is connected, and a first connecting rod 812 is fixedly connected between the sliding seat 811 and the rack 809. The first connecting rod 812 is L-shaped. A second connecting rod 813 is fixedly connected between the sliding seat 811 and the second brush 803. The second connecting rod 813 is L-shaped. The reset component 10 includes a support seat 101. The support seat 101 is L-shaped and fixedly connected to the outer surface of the photovoltaic panel body 3. A second spring 102 is elastically connected between the support seat 101 and the first brush 802. The second spring 102 is used for the reset of the first brush 802.

[0041] In practical use, when the photovoltaic panel body 3 is raised, the second gear 807 on the second rotating shaft 806 rolls on the arc-shaped rack 707. At this time, the second gear 807 rotates on the second rotating shaft 806 under the action of the one-way bearing. When the temperature of the chamber 501 decreases and the photovoltaic panel body 3 is lowered, the rolling of the second gear 807 on the arc-shaped rack 707 will drive the second rotating shaft 806 to rotate together. At this time, the rotation of the second rotating shaft 806 will drive the third gear 808 to rotate. The rotation of the third gear 808 will drive the spur rack 809, which in turn will drive the first connecting rod 812 to make the sliding seat 811 slide on the slide rail 810. The sliding seat 811 drives the second connecting rod 813 to make the second brush 803 slide on the sliding frame 801 toward the middle position of the photovoltaic panel body 3. At this time, the second brush 803 will pull the steel wire rope 804 to drive the first brush 802 to slide toward the middle position of the photovoltaic panel body 3 under the action of the pulley 805, thereby cleaning the photovoltaic panel body 3. The sliding of the first brush 802 will stretch the second spring 102. When the photovoltaic panel body 3 is lowered to the bottom, the second gear 807 will disengage from the arc rack 707. At this time, the second spring 102 will pull the first brush 802 to reset, and the first brush 802 will also pull the steel wire rope 804 to reset the second brush 803.
