Description

Technical Field

[0001] This application relates to the field of building roofing technology, and in particular to an energy-saving building roofing structure and construction method. Background Technology

[0002] Currently, solar panels are often installed on the top of building rooftops to store electricity and supply it for daily use, thereby achieving effective utilization of solar energy and energy conservation and emission reduction in buildings.

[0003] In some windy, sandy, and hazy areas, rainwater often carries dust, sand, and other impurities from the air. When rainwater falls onto the surface of solar panels, these impurities tend to remain and accumulate on the surface of the solar panels. This accumulation of impurities significantly reduces the solar radiation received by the solar panels, thus affecting their solar energy conversion. Summary of the Invention

[0004] In order to prevent impurities carried by rainwater from accumulating on the surface of solar panels, this application provides an energy-saving building roof structure and construction method.

[0005] In the first aspect, this application provides an energy-saving building roof structure, which adopts the following technical solution:

[0006] An energy-saving building roof structure includes a floor slab, solar panels inclinedly mounted on the floor slab, a flexible protective plate disposed between the floor slab and the solar panels, one end of the flexible protective plate being bent and extending above the inclined upper end of the solar panels, a scraper being fixedly disposed at the end of the flexible protective plate above the solar panels, the scraper being slidably attached to the upper surface of the solar panels, and the floor slab being provided with:

[0007] Two drive components are symmetrically arranged on the two inclined sides of the solar panel. Both drive components are used to drive the scraper to slide in a direction close to or away from the inclined lower end of the solar panel.

[0008] The lower reservoir is used to collect and filter rainwater;

[0009] The cleaning system is used to draw filtered water from the reservoir and rinse the surface of the solar panels.

[0010] By adopting the above technical solution, in rainy weather, staff activate the drive assembly and cleaning mechanism. The scraper slides along the inclined lower end of the solar panel, removing dust from the panel as it moves. Meanwhile, the cleaning mechanism draws filtered water to rinse the surface of the solar panel, ensuring its cleanliness. During the scraper's movement, a flexible protective plate covers the solar panel, preventing rainwater from falling onto its upper surface and making it difficult for impurities to adhere. In smoggy or dusty weather, staff can adjust the scraper by adjusting the drive assembly to allow the flexible protective plate to cover the solar panel, reducing the accumulation of dust and other impurities on its surface. In sunny weather, the flexible protective plate is laid between the solar panel and the floor slab, providing insulation and effectively reducing indoor temperature.

[0011] Optionally, the drive assembly includes two rotating wheels rotatably mounted on the floor slab and a drive component for driving one of the rotating wheels to rotate. A drive chain is wound between the two drive wheels. The transmission direction of the upper end of the drive chain is consistent with the tilt direction of the solar panel. A mounting plate is fixed on the drive chain and the mounting plate is connected to the scraper.

[0012] By adopting the above technical solution, the driving component drives a transmission wheel to rotate, the rotating transmission wheel drives the transmission chain to rotate, and the rotating transmission chain drives the mounting plate to slide synchronously. Then the sliding mounting plate drives the scraper to move, thereby realizing the scraper to slide along the direction close to or away from the inclined lower end of the solar panel.

[0013] Optionally, the cleaning mechanism includes:

[0014] The nozzle is fixed on the mounting plate with the water outlet facing the solar panel;

[0015] A water supply assembly is used to draw filtered water from the lower water storage tank and supply water to the inlet end of the nozzle.

[0016] A lower adjustment component is used to adjust the nozzle to the side of the scraper away from the inclined lower end of the solar panel;

[0017] An upper adjustment component is used to adjust the nozzle to the side of the scraper near the lower inclined end of the solar panel.

[0018] By adopting the above technical solution, when the drive component drives the scraper to slide along the inclined lower end of the solar panel, the upper adjustment component adjusts the nozzle to the side of the scraper close to the inclined lower end of the solar panel. This allows the scraper to move downwards and remove dust from the solar panel surface, while the nozzle sprays water to pre-wet the solar panel surface, ensuring the dust adheres and is soaked in the water. This facilitates the scraping operation and avoids scratches on the solar panel surface and the scraper surface caused by dry scraping. When the drive component drives the scraper to move away from the lower end of the solar panel, the lower adjustment component adjusts the nozzle to the side of the scraper away from the inclined lower end of the solar panel. This allows the scraper to move upwards and remove dust from the solar panel surface, while the nozzle sprays water to rinse the solar panel surface and wash away the dust scraped off the scraper, ensuring the scraper's dust removal performance on the solar panel surface.

[0019] Optionally, the water supply assembly includes a water pump and an outlet hose. The water pump is installed in the lower water storage tank and is used to draw filtered water from the lower water storage tank. One end of the outlet hose is connected to the outlet end of the water pump, and the other end is connected to the inlet end of the nozzle.

[0020] By adopting the above technical solution, the staff started the water pump, which drew the filtered water from the water storage tank. Then, the water pump drew the filtered water to the nozzle through the water outlet hose, so that the nozzle sprayed the filtered water to clean the surface of the solar panel.

[0021] Optionally, the mounting plate has a groove on the side facing the scraper, and a slider adapted to slide along the groove is fixed at one end of the scraper. The sliding direction of the slider is consistent with the tilt direction of the solar panel. The mounting plate has a mounting groove communicating with the groove. An adjusting plate is slidably installed in the mounting groove along the direction close to or away from the scraper. A telescopic spring is connected between the end of the adjusting plate away from the scraper and the inner wall of the mounting groove. A protrusion is fixed at the end of the adjusting plate close to the scraper, and an insertion hole is opened on the side of the slider away from the scraper.

[0022] The down-adjustment component includes:

[0023] The lower insertion rod is fixed to the adjustment plate and located on the side of the nozzle that is tilted towards the lower end of the solar panel. The lower insertion rod is adapted to be inserted into the insertion hole.

[0024] The lower positioning plate is fixed to the floor slab and located on the side of the inclined lower end of the solar panel away from the inclined upper end of the solar panel;

[0025] A sliding plate is located on the side of the protrusion facing the scraper and is slidably installed in the mounting groove along the extension direction of the sliding groove. One end of the sliding plate facing the lower inclined end of the solar panel extends through the mounting plate and abuts against the lower positioning plate in a separable manner. The sliding plate slides against the side of the protrusion facing the scraper, and the distance between the two sides of the sliding plate that are close to or far from the protrusion gradually increases along the direction from the upper inclined end to the lower inclined end of the solar panel.

[0026] An adjusting spring is installed in the mounting groove, with one end fixedly connected to the inner wall of the mounting plate and the other end fixedly connected to the upper inclined end of the sliding plate facing the solar panel.

[0027] By adopting the above technical solution, the driving component drives the mounting plate to move towards the inclined lower end of the solar panel. When the mounting plate moves to the side of the inclined lower end of the solar panel away from the inclined upper end of the solar panel and the sliding plate presses down the positioning plate, the distance between the two sides of the sliding plate that are close to or away from the protrusion gradually increases along the direction from the inclined upper end to the inclined lower end of the solar panel. This causes the sliding plate to press down on the protrusion and move the protrusion away from the solar panel. Then, the pressed protrusion drives the lower insertion rod to move synchronously through the adjusting plate, so that the lower insertion rod moves away from the scraper. Then, the driving component stops driving the mounting plate, and the scraper continues to slide downwards under the action of gravity, so that the scraper slides to the lower insertion rod. At this time, the scraper completes the scraping of the upper surface of the solar panel and the flexible protective plate covers the upper surface of the solar panel. When the flexible protective plate is not needed to cover the solar panel, the drive assembly moves the mounting plate towards the tilted upper end of the solar panel. The mounting plate then separates from the positioning plate, and returns to its original position under the elastic force of the adjusting spring, preventing it from pressing against the protrusion. The adjusting plate then returns to its original position under the restoring force of the telescopic spring, causing the lower insert rod on the adjusting plate to insert into the slot of the slider. This adjusts the nozzle to the side where the scraper is away from the tilted lower end of the solar panel. The adjustment of the relative position between the nozzle and the scraper is achieved through gravity, effectively reducing the use of electric equipment and energy consumption, thus achieving energy conservation and emission reduction.

[0028] Optionally, the upper adjustment component includes:

[0029] A positioning pressure plate is fixed on the adjustment plate, and its lower end penetrates through the mounting plate. The bottom surface of the positioning pressure plate is inclined downward along the direction from the pressure plate to the mounting plate.

[0030] The upper positioning plate is movably mounted on the floor slab and located on the side of the lower inclined end of the solar panel away from the upper inclined end of the solar panel;

[0031] A linear locator is installed on the floor slab and is used to drive the upper locating plate to press or release the bottom surface of the locating pressure plate;

[0032] An upper insertion rod is fixed to the adjustment plate and located on the side of the nozzle that is inclined downward away from the solar panel. The upper insertion rod is adapted to be inserted into the insertion hole.

[0033] By adopting the above technical solution, when the driving component drives the mounting plate to move to the inclined upper end of the solar panel and the positioning plate is above the upper positioning plate, the linear positioner drives the upper positioning plate to press the bottom surface of the positioning plate. Since the bottom plate of the positioning plate is inclined downward along the direction from the pressure plate to the mounting plate, the pressed positioning plate moves away from the scraper, thereby separating the lower insertion rod from the insertion hole on the slider. Then the driving component stops working. At this time, the lower end of the flexible protective plate pulls the upper end of the flexible protective plate, causing the flexible protective plate to drive the pressure plate to move along the inclined lower end of the solar panel, thereby causing the pressure plate to slide to the upper insertion rod. At this time, the nozzle is located on the side of the scraper close to the inclined lower end of the solar panel.

[0034] Optionally, the lower water storage tank is located on the side of the solar panel that is away from the inclined upper end of the solar panel at the lower end of the solar panel. The upper end of the lower water storage tank has an opening, and the inclined lower end of the solar panel is connected to a conveying plate that extends to the opening.

[0035] By adopting the above technical solution, when the drive component drives the scraper to move along the inclined upper end to the inclined lower end of the solar panel, the clean water sprayed from the nozzle and the rainwater scraped off the solar panel by the scraper slide down the inclined surface of the solar panel and the surface of the conveyor plate into the lower water storage tank, so as to realize the recycling of rainwater and washing water.

[0036] Optionally, an upper water storage tank is provided on the side of the floor slab located at the lower end of the inclined solar panel away from the upper end of the inclined solar panel. The upper water storage tank has a water outlet on the side facing the solar panel. A guide plate is provided on the outer wall of the upper water storage tank for guiding clean water to the upper surface of the solar panel. The inner wall of the upper water storage tank is adjustablely provided with a sealing plate for closing or opening the water outlet.

[0037] By adopting the above technical solution, when the driving component drives the pressure plate to move to the upper end of the solar panel, the sealing plate on the upper water tank is adjusted so that the outlet is in the open state. At this time, the clean water in the upper water tank flows along the outlet to the guide plate, and then the clean water flows along the guide plate to the surface of the flexible protective plate to clean the surface of the flexible protective plate.

[0038] Optionally, a push rod is fixed to the side of the flexible protective plate away from the scraper, corresponding to the sealing plate. One end of the sealing plate is hinged to the inner wall of the upper water storage tank, and the push rod can press the sealing plate separately.

[0039] By adopting the above technical solution, when the driving component drives the pressure plate to move to the upper end of the solar panel, the push plate on the flexible protective plate presses the sealing plate, causing the pressed sealing plate to open the water outlet, so that the clear water in the upper water storage tank can flow out smoothly along the water outlet.

[0040] Secondly, this application provides a construction method for an energy-saving building roof structure, employing the following technical solution:

[0041] A construction method for an energy-efficient building roof structure includes the following steps:

[0042] Step 1: Pour the floor slab on the building's roof;

[0043] Step 2: Install flexible protective panels on the floor slab;

[0044] Step 3: Install solar panels on the floor slab;

[0045] Step 4: Install the drive assembly on the floor slab, adjust one end of the flexible protective plate to extend above the solar panel, fix the scraper on the flexible protective plate, and then install the slider on the scraper into the inner cavity of the groove of the mounting plate.

[0046] Step 5: Install a water storage tank on the upper inclined end of the solar panels on the floor slab, and install a lower water storage tank on the lower inclined end of the solar panels on the floor slab.

[0047] Step 6: Fix the nozzles to the mounting plate and install the water supply components on the floor slab at the lower water tank to enable the lower water tank to supply water to the nozzles;

[0048] Step 7: Insert the upper rod on the mounting plate into the slot of the slider, and adjust the drive assembly and cleaning mechanism to make the scraper slide back and forth three times on the surface of the solar panel. By adopting the above technical solution, the floor slab, solar panel, and flexible protective plate are installed in sequence, so that the building roof has multiple layers of protection. The drive assembly and cleaning mechanism are adjusted in sequence so that when the flexible protective plate drives the scraper and the nozzle to move synchronously, the scraper removes dust from the surface of the solar panel, while the nozzle sprays clean water to clean the surface of the solar panel.

[0049] In summary, this application includes at least one of the following beneficial technical effects:

[0050] 1. The scraper removes dust from the solar panel during its movement. Then, the moving scraper drives a flexible protective plate to cover the solar panel, preventing rainwater from falling onto the top surface of the solar panel and making it difficult for impurities in the rainwater to adhere to the top surface of the solar panel.

[0051] 2. When the drive component drives the scraper to move along the lower end of the solar panel, the lower adjustment component adjusts the nozzle to the side of the scraper away from the tilted lower end of the solar panel, so that when the scraper moves upward and scrapes off the dust on the surface of the solar panel, the clean water sprayed from the nozzle washes the surface of the solar panel and washes off the dust that has fallen onto the surface of the scraper.

[0052] 3. When the drive unit drives the scraper to move along the inclined upper end to the inclined lower end of the solar panel, the clean water sprayed from the nozzle and the rainwater scraped off the solar panel by the scraper slide down the inclined surface of the solar panel and the surface of the conveyor plate into the lower water storage tank, so as to realize the recycling of rainwater and washing water.

[0061] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0062] This application discloses an energy-saving building roof structure. (Refer to...) Figure 1 and Figure 2 An energy-saving building roof structure includes a floor slab 1 laid at an angle on the roof. A protective edge 11 is integrally formed on the upper surface of the floor slab 1 along its perimeter. A rainwater pipe 12, connecting to the bottom of the floor slab 1, is vertically installed on the floor slab 1. Solar panels 2, used to supply power to indoor electrical equipment, are mounted at an angle on the floor slab 1 via mounting brackets. A flexible protective plate 3 is laid between the floor slab 1 and the solar panels 2 along the laying direction of the solar panels 2. The upper end of the flexible protective plate 3 is bent and extends above the inclined upper end of the solar panels 2. A scraper 4 is fixedly installed at the end of the flexible protective plate 3 above the solar panels 2, and the lower surface of the scraper 4 slides in contact with the upper surface of the solar panels 2.

[0063] The floor slab 1 is equipped with a drive assembly, a lower water storage tank 5, and a cleaning mechanism. Two drive assemblies are symmetrically arranged on the two inclined sides of the solar panel 2. Both drive assemblies are used to drive the scraper 4 to slide along the direction close to or away from the inclined lower end of the solar panel 2. The lower water storage tank 5 is used to collect and filter rainwater. The cleaning mechanism is used to extract the filtered water in the lower water storage tank 5 and rinse the surface of the solar panel 2. A control module for controlling the operation of the drive assembly is also installed inside the building.

[0064] During rainy weather, to prevent impurities mixed in rainwater from adhering to the upper surface of the solar panel 2, the control module is adjusted to operate the drive components and cleaning mechanism. The scraper 4 slides along the inclined lower end of the solar panel 2, scraping away dust as it moves. Meanwhile, the cleaning mechanism draws filtered water to rinse the upper surface of the solar panel 2, ensuring its cleanliness. As the scraper 4 moves, it also pulls a flexible protective plate 3 to cover the solar panel 2, preventing rainwater from falling onto its upper surface and thus preventing impurities from adhering.

[0065] Reference Figure 1 and Figure 2 In this embodiment, the solar panel 2 is rectangular and is arranged parallel to the floor slab 1. The driving assembly includes two rotating wheels 61 rotatably mounted on the floor slab 1 and a driving component 62 for driving one of the rotating wheels 61 to rotate. The driving component 62 is a drive motor, which is electrically connected to the control module and to the output terminal of the solar panel 2 via a power transmission line. The two rotating wheels 61 are spaced apart along the tilt direction of the solar panel 2, and a transmission chain 63 is wound between the two rotating wheels 61. The transmission direction of the upper end of the transmission chain 63 is consistent with the tilt direction of the solar panel 2. A mounting plate 7 is fixedly connected to the transmission chain 63, and the mounting plate 7 is connected to the scraper 4. To improve the sliding stability of the flexible protective plate 3, a guide strip 13 is fixedly installed on the floor slab 1 between the floor slab 1 and the solar panel 2. The guide strip 13 is set parallel to the solar panel 2. A counterweight sliding block (not shown in the figure) is fixed at the lower end of the flexible protective plate 3. The sliding block is slidably installed on the guide strip 13, and the sliding direction is parallel to the tilt direction of the solar panel 2.

[0066] In use, the drive unit 62 drives a rotating wheel 61 to rotate, and the rotating wheel 61 drives the transmission chain 63 to rotate, thereby driving the mounting plate 7 to slide synchronously through the rotating transmission chain 63; then the sliding mounting plate 7 drives the scraper 4 to move, thereby realizing the scraper 4 to slide along the direction close to or away from the inclined lower end of the solar panel 2.

[0067] Reference Figure 2 , Figure 3 and Figure 4In order to effectively clean the surface of the solar panel 2 during the process of scraping dust off the surface of the solar panel 2 by the movement of the scraper 4, the cleaning mechanism includes a nozzle 81, a water supply assembly 82, a lower adjustment assembly 83, and an upper adjustment assembly 84. The nozzle 81 is fixedly installed in the middle of the mounting plate 7 by a support base, with the water outlet of the nozzle 81 facing the solar panel 2. The water supply assembly 82 is used to draw filtered water from the lower water tank 5 and supply water to the water inlet of the nozzle 81. The lower adjustment assembly 83 is used to adjust the nozzle 81 to the side of the scraper 4 away from the lower inclined end of the solar panel 2. The upper adjustment assembly 84 is used to adjust the nozzle 81 to the side of the scraper 4 close to the lower inclined end of the solar panel 2.

[0068] Before the drive assembly moves the scraper 4 along the inclined upper end to the inclined lower end of the solar panel 2, the upper adjustment assembly 84 first adjusts the nozzle 81 to the side of the scraper 4 closer to the inclined lower end of the solar panel 2, so that the nozzle 81 sprays filtered water onto the surface of the solar panel 2 to wash away the dirt scraped off by the scraper 4 through the water flow. Before the drive assembly moves the scraper 4 along the inclined lower end to the inclined upper end of the solar panel 2, the lower adjustment assembly 83 adjusts the nozzle 81 to the side of the scraper 4 away from the inclined lower end of the solar panel 2, so that when the drive assembly moves the scraper 4 towards the inclined upper end of the solar panel 2, the filtered water sprayed by the nozzle 81 can wash away the dirt scraped off the upper surface of the scraper 4.

[0069] Reference Figure 1 and Figure 2 The water supply assembly 82 includes a water pump and a water outlet hose 821. The water pump is installed in the lower water storage tank 5 and is used to draw filtered water from the lower water storage tank 5. The water pump is a submersible pump and is electrically connected to the power supply terminal of the solar panel 2 and to the control module. The water outlet hose 821 is installed on the floor slab 1. One end of the water outlet hose 821 penetrates the inner wall of the lower water storage tank 5 and is connected to the water outlet terminal of the water pump. The other end of the water outlet hose 821 is connected to the water inlet terminal of the nozzle 81.

[0070] To facilitate water storage operations in the lower reservoir 5, refer to Figure 1 The lower water storage tank 5 is located on the side of the inclined lower end of the solar panel 2 away from the inclined upper end of the solar panel 2. The upper end of the lower water storage tank 5 has an opening, and a filter screen is laid flat inside the lower water storage tank 5. A water purifier for purifying the stored water is installed inside the lower water storage tank 5. A conveyor plate extending to the opening is laid flat and connected to the inclined lower end of the solar panel 2.

[0071] Reference Figure 3 and Figure 4In this embodiment, a sliding groove 71 is provided on the side of the mounting plate 7 facing the scraper 4. The sliding groove 71 is a T-shaped groove. A slider 41 is integrally formed on one end of the scraper 4 along the length direction, which is adapted to slide in the sliding groove 71. The sliding direction of the slider 41 is consistent with the tilt direction of the solar panel 2. A mounting groove 72 is provided on the mounting plate 7, which is connected to the sliding groove 71. An adjusting plate 73 is slidably installed in the mounting groove 72 along the direction close to or away from the scraper 4. A telescopic spring 74 is connected between the end of the adjusting plate 73 away from the scraper 4 and the inner wall of the mounting groove 72. A protrusion 731 is glued to the end of the adjusting plate 73 close to the scraper 4. An insertion hole is provided on the side of the slider 41 away from the scraper 4.

[0072] Reference Figure 4 and Figure 5 The lower adjustment assembly 83 includes a lower insertion rod 831, a lower positioning plate 832, a sliding plate 833, and an adjustment spring 834. The lower insertion rod 831 is welded to the adjustment plate 73 and is located on the side of the nozzle 81 facing the lower inclined end of the solar panel 2. The end of the lower insertion rod 831 away from the adjustment plate 73 is inserted into the socket. The lower positioning plate 832 is mounted on the floor slab 1 by expansion bolts and is located on the side of the lower inclined end of the solar panel 2 away from the upper inclined end of the solar panel 2. The sliding plate 833 is located on the side of the protrusion 731 facing the scraper 4 and is slidably installed in the mounting groove 72 along the extension direction of the sliding groove 71. The end of the sliding plate 833 facing the lower inclined end of the solar panel 2 extends through the mounting plate 7 and the through end of the sliding plate 833 is detachably abutted against the lower positioning plate 832. The distance between the two sides of the sliding plate 833 near or away from the protrusion 731 increases along the direction from the upper inclined end to the lower inclined end of the solar panel 2. The side of the sliding plate 833 near the protrusion 731 slides and fits against the side of the protrusion 731 facing the scraper 4. The adjusting spring 834 is disposed in the mounting groove 72, and one end of the adjusting spring 834 is fixedly connected to the inner wall of the mounting plate 7, and the other end is fixedly connected to the end of the sliding plate 833 facing the upper inclined end of the solar panel 2.

[0073] In use, the drive assembly drives the mounting plate 7 to move towards the inclined lower end of the solar panel 2. When the mounting plate 7 moves to the side of the inclined lower end of the solar panel 2 away from the inclined upper end of the solar panel 2 and the sliding plate 833 presses down the positioning plate 832, the sliding plate 833 presses down the protrusion 731 and moves the protrusion 731 away from the solar panel 2. The pressed protrusion 731 drives the lower insertion rod 831 to move synchronously through the adjusting plate 73, so that the lower insertion rod 831 moves away from the scraper 4. Then the drive assembly stops driving the mounting plate 7. Since the flexible protective plate 3 covers most of the upper surface of the solar panel 2, the scraper 4 continues to slide downward under the push of the flexible protective plate 3 and its own gravity, so that the scraper 4 slides to the inner bottom wall of the groove 71 and the insertion hole on the scraper 4 is directly opposite the lower insertion rod 831. At this time, the scraper 4 completes the scraping of the upper surface of the solar panel 2 and the flexible protective plate 3 covers the upper surface of the solar panel 2. When the flexible protective plate 3 is no longer needed to cover the solar panel 2, the drive assembly drives the mounting plate 7 to move towards the inclined upper end of the solar panel 2. Then, the mounting plate 7 separates from the lower positioning plate 832. The mounting plate 7 then returns to its original position under the elastic force of the adjusting spring 834, so that the mounting plate 7 no longer presses the protrusion 731. Then, the adjusting plate 73 returns to its original position under the restoring force of the telescopic spring 74, so that the lower insertion rod 831 on the adjusting plate 73 is inserted into the insertion hole of the slider 41. This adjusts the nozzle 81 to the side of the scraper 4 away from the inclined lower end of the solar panel 2, so that when the scraper 4 moves from the inclined lower end of the solar panel 2 to the inclined upper end of the solar panel, the filtered water sprayed by the nozzle 81 can wash away the dirt scraped off the upper surface of the scraper 4.

[0074] Reference Figure 1 and Figure 2 Furthermore, as the scraper 4 moves along the inclined lower end of the solar panel 2 to the inclined upper end of the solar cell, in order to enable the scraper 4 to efficiently clean the surface of the solar panel 2, a cleaning agent storage tank 9 is also installed on the floor slab 1. The cleaning agent storage tank 9 is equipped with a micro supply pump, which is electrically connected to the power supply terminal of the solar panel 2 and to the control module. The water supply terminal of the micro supply pump is connected to a cleaning nozzle 92 through a supply hose 91. The cleaning nozzle 92 is fixed to the side of the nozzle 81 near the inclined upper end of the solar panel 2 by a mounting base. As the scraper 4 moves along the inclined lower end to the inclined upper end of the solar panel 2, the control module also controls the micro supply pump to work, so as to spray the cleaning agent in the cleaning agent storage tank 9 onto the surface of the solar panel 2 through the supply hose 91 and the cleaning nozzle 92, so that the cleaning agent mixes with the clean water sprayed from the nozzle 81 to form cleaning water, which is used to remove dirt from the surface of the solar panel 2. Then the wastewater is scraped off by the scraper 4 onto the surface of the floor slab 1 on both sides of the solar panel 2 and discharged through the rainwater pipe 12.

[0075] Furthermore, refer to Figure 5 and Figure 6 When the scraper 4 moves to the upper inclined end of the solar panel 2, in order to facilitate the scraper 4 moving from the upper inclined end of the solar panel 2 to the lower inclined end of the solar panel 2, the nozzle 81 can spray clean water onto the surface of the solar panel 2 on the side facing downwards. The upper adjustment assembly 84 includes a positioning pressure plate 841, an upper positioning plate 842, a linear positioner 843, and an upper insertion rod 844. The positioning pressure plate 841 is bonded to the adjustment plate 73 and its lower end extends through the lower end of the mounting plate 7. The bottom surface of the positioning pressure plate 841 is inclined and tilted downwards along the direction from the pressure plate to the mounting plate 7. The linear positioner 843 is an electric push rod, which is fixedly installed on the floor slab 1 and the extension direction of its telescopic rod is perpendicular to the sliding direction of the scraper 4. The electric push rod is located on the side of the lower inclined end of the solar panel 2 away from the upper inclined end of the solar panel 2.

[0076] The upper positioning plate 842 is fixed on the piston rod of the electric push rod 33. The length direction of the upper positioning plate 842 is parallel to the sliding direction of the scraper 4. The upper end face of the upper positioning plate 842 is inclined and tilted upward along the direction from the scraper 4 to the mounting plate 7. The upper end face of the upper positioning plate 842 presses or releases the lower inclined surface of the positioning pressure plate 841 under the drive of the electric push rod. The upper insertion rod 844 is welded to the adjustment plate 73 and is located on the side of the nozzle 81 away from the inclined lower end of the solar panel 2. The upper insertion rod 844 is inserted and adapted to the insertion hole.

[0077] When the drive assembly moves the mounting plate 7 to the inclined upper end of the solar panel 2 and the positioning plate 841 is above the upper positioning plate 842, the linear positioner 843 drives the upper positioning plate 842 to press the bottom surface of the positioning plate 841. The pressed positioning plate 841 moves away from the scraper 4, thereby separating the lower insertion rod 831 from the insertion hole on the slider 41. Then the drive assembly stops working. Since the flexible protective plate 3 is mostly located between the floor slab 1 and the solar panel 2 at this time, the lower end of the flexible protective plate 3 located below the solar panel 2 pulls the upper end of the flexible protective plate 3, causing the flexible protective plate 3 to drive the scraper 4 to move along the inclined lower end to the inclined upper end of the solar panel 2, thereby causing the scraper 4 to slide to the top wall of the chute 71. At this time, the insertion hole on the scraper 4 is directly opposite the upper insertion rod 844, and the nozzle 81 is located on the side of the scraper 4 near the inclined lower end of the solar panel 2.

[0078] Reference Figure 1 and Figure 7Because the flexible protective panel 3 will accumulate a large amount of impurities from the environment on its upper surface after being used to cover the solar panel 2, an upper water storage tank 14 is installed on the floor slab 1 on the side of the solar panel 2 away from its inclined upper end for cleaning the flexible protective panel 3. The upper end of the upper water storage tank 14 is open, and a filter screen 141 is laid flat inside the upper water storage tank 14. A water outlet is opened on the side of the upper water storage tank 14 facing the solar panel 2, and a sealing plate 142 is installed on the inner wall of the upper water storage tank 14 at the water outlet. The upper end of the sealing plate 142 is hinged to the inner wall of the upper water storage tank 14, and the lower end of the sealing plate 142 covers the water outlet. A guide plate 143 is fixedly connected to the outer wall of the upper water storage tank 14 below the water outlet. The end of the guide plate 143 away from the upper water storage tank 14 is inclined downward and slides relative to the upper surface of the flexible protective plate 3, so that the end of the guide plate 143 scrapes off the stains adhering to the flexible protective plate 3 during the movement of the flexible protective plate 3.

[0079] Reference Figure 2 and Figure 7 The upper surface of the guide plate 143 has integrally formed flanges on both sides in its width direction. The flexible protective plate 3 is located at one end of the upper part of the solar panel 2, and a surrounding plate 31 is bonded to the periphery of the flexible protective plate 3. The surrounding plate 31 and the upper surface of the flexible protective plate 3 form a dirt storage space. A drain pipe 32 is horizontally inserted through the surrounding plate 31, with one end of the drain pipe 32 extending into the inside of the surrounding plate 31 and the other end facing the surface of the floor slab 1. A push rod 33 is fixed to the side of the flexible protective plate 3 away from the scraper 4 corresponding to the sealing plate 142. When the flexible protective plate 3 moves the pressure plate along the direction from the lower end to the upper end of the inclined solar panel 2, and the scraper 4 slides to the upper insertion rod 844, the enclosure 31 abuts against the flap on the guide plate 143, the push rod 33 on the flexible protective plate 3 is inserted into the outlet and pushes open the sealing plate 142, so that the outlet is in the open state. Then the filtered water in the upper water storage tank 14 flows out along the outlet and washes into the stain pre-storage space. Then the filtered water carries the stains along the drain pipe 32 to the surface of the floor slab 1, and then along the rainwater pipe 12 on the floor slab 1 to the ground.

[0080] The implementation principle of an energy-saving building roof structure according to an embodiment of this application is as follows: In rainy weather, the staff adjusts the control module so that the drive component drives the scraper 4 to slide at the inclined upper end of the solar panel 2 in the direction of the inclined lower end of the solar panel 2; during this process, the water sprayed from the nozzle 81 pre-wets the surface of the solar panel 2 so that the dust is pre-adhered and soaked in the water, and the scraper 4 moves downward and scrapes off the dust on the surface of the solar panel 2 so that the scraper 4 can perform the dust removal operation, so that the moving scraper 4 drives the flexible protective plate 3 to cover the solar panel 2.

[0081] After the rainfall ends, the staff adjusts the control module, causing the scraper 4 to move upward and scrape away the dust on the surface of the solar panel 2. The nozzle 81 sprays clean water, and the cleaning nozzle 92 sprays cleaning agent, thus rinsing the surface of the solar panel 2 with the cleaning water mixed with cleaning agent and washing away the dust on the scraper 4, ensuring the scraper 4's ability to remove dust from the surface of the solar panel 2. Then, the moving scraper 4 drives the flexible protective plate 3 back to its original position. When the scraper 4 moves to the upper end of the solar panel 2, the push rod 33 on the flexible protective plate 3 inserts into the outlet of the upper water storage tank 14 and pushes open the sealing plate 142, thus opening the outlet. The filtered water in the upper water storage tank 14 flows out along the outlet and washes into the stain pre-storage space. Then, the filtered water carries the stains along the drain pipe 32 to the surface of the floor slab 1, thus cleaning the stains on the flexible protective plate 3.

[0082] This application also discloses a construction method for an energy-saving building roof structure. The construction method for the energy-saving building roof structure includes the following steps:

[0083] Step 1: Pour floor slab 1 on the building roof;

[0084] Step 2: Install flexible protective panel 3 on floor slab 1;

[0085] Step 3: Install solar panels 2 on floor slab 1;

[0086] Step 4: Install the drive assembly on the floor slab 1, adjust one end of the flexible protective plate 3 to extend above the solar panel 2, fix the scraper 4 on the flexible protective plate 3, and then install the slider 41 on the scraper 4 into the inner cavity of the groove 71 of the mounting plate 7.

[0087] Step 5: Install a water storage tank 14 on the upper inclined end of the solar panel 2 on the floor slab 1, and install a lower water storage tank 5 on the lower inclined end of the solar panel 2 on the floor slab 1.

[0088] Step 6: Fix the nozzle 81 on the mounting plate 7, and install the water supply component 82 on the floor slab 1 at the lower water storage tank 5 to realize the water supply from the lower water storage tank 5 to the nozzle 81.

[0089] Step 7: Insert the upper insertion rod 844 on the mounting plate 7 into the insertion hole of the slider 41, and adjust the drive assembly and cleaning mechanism so that the scraper 4 completes no less than three reciprocating slides on the surface of the solar panel 2.

[0090] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
