Description

Technical Field

[0001] The present application relates to the technical field of solar photovoltaic panels, and more specifically to an intelligent solar building roof. Background Art

[0002] Solar photovoltaic power generation system is a new type of power generation system that directly converts solar energy into electrical energy through the photovoltaic effect of solar cell semiconductor materials under sunlight radiation. Solar photovoltaic power generation system has two modes: independent operation and grid-connected operation. Independent photovoltaic power generation system requires batteries as energy storage devices, and is mainly used in remote areas without power grids and areas with dispersed populations; in areas with public power grids, photovoltaic power generation systems are connected to the power grid and run in parallel, which has higher power generation efficiency and better environmental performance.

[0003] The existing solar photovoltaic panels used in buildings are generally installed on the roof of the building to absorb more solar radiation and obtain power supply. However, solar photovoltaic panels installed on the roof have problems such as maintenance and dust accumulation during long-term use. When maintaining the photovoltaic panels, maintenance personnel need to climb to the roof to inspect and remove dust one by one; and in severe weather such as heavy rain, snow or strong wind, the surface of the photovoltaic panels will be worn, resulting in a reduction in the service life of the photovoltaic panels, making it difficult for them to play their due role.

[0004] In view of this, the inventors designed an intelligent solar building roof to address the above-mentioned problems, and this case was thus created. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent solar building roof, which has the advantages of intelligent positioning and alarming for maintenance, automatic adjustment to clean dust on photovoltaic panels, and the effect of extending the service life of photovoltaic panels.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent solar building roof, comprising: a support frame, a photovoltaic system, a connector, and a master controller.

[0007] The support frame is arranged on the roof and is composed of a plurality of vertical frames and a plurality of horizontal frames. The horizontal frames are provided with installation slots for installing the photovoltaic system, the connector and the master controller;

[0008] The photovoltaic system is installed on the horizontal frame, used for photoelectric conversion, and has the functions of automatic cleaning and protection; the connector is installed on the horizontal frame, composed of a connector and a connecting wire, and is useful for connecting several photovoltaic systems together;

[0009] The master controller is installed on the support frame, used to summarize and control the operating conditions of several photovoltaic systems and is connected to the house power grid. It has an Internet of Things module that is connected to the control terminal signal.

[0010] By adopting the above technical solution, before using the solar building roof, the support frame can be first fixed on the roof of the house, so that several vertical frames are used to support several horizontal frames, and then the photovoltaic system is installed on the horizontal frame and arranged closely along the horizontal frame, and then several photovoltaic systems are connected to the main controller through the connector; when using solar power generation, the photovoltaic system can convert solar energy into electrical energy and summarize it to the main controller through the connector, and each photovoltaic system transmits its related work operation information to the main controller; when any photovoltaic system has a reduced power generation capacity due to dust accumulation, its corresponding internal monitoring will start the dust cleaning device on the photovoltaic system to clean the photovoltaic system; when encountering thunder In rainy or snowy days, the control terminal and local weather monitoring equipment collect information and transmit the information to the main controller through the Internet of Things module, so that the main controller transmits the command to each photovoltaic system through the connector. After receiving the command, the photovoltaic system starts the protection measures to protect the photovoltaic system. When any photovoltaic system is damaged and the photoelectric conversion power is lower than the average value for a long time, the photovoltaic system will be optimized through its own dust removal process. If there is still no improvement after the dust removal process is optimized, the corresponding photovoltaic system will send its location to the main controller, and the main controller will transmit the relevant location information of the damaged photovoltaic system to the control terminal through the Internet of Things module.

[0011] In summary, the photovoltaic system, the connector and the main controller are controlled by the support frame, and then the photovoltaic system performs photoelectric conversion and performs dust removal through self-monitoring. The main controller monitors the weather through the control terminal and issues instructions to the photovoltaic system for self-protection, thereby achieving intelligent positioning, point warning and maintenance, automatic adjustment to clean dust on the photovoltaic panels, and extending the service life of the photovoltaic panels.

[0012] The present invention is preferably: the photovoltaic system includes a shell arranged on a horizontal frame, a photovoltaic panel arranged in the shell and used to receive solar energy, two rotating rollers arranged in the shell and respectively located at the corresponding two ends of the photovoltaic panel, a rotating belt arranged on the two rotating rollers and tightened between the two, a plurality of dust removal strips arranged on the side of the rotating belt facing the photovoltaic panel and used to clean dust on the photovoltaic panel, a driving motor arranged in the shell and the rotating shaft is connected to any rotating roller, a sub-controller arranged in the shell and electrically connected to the photovoltaic panel, a battery arranged in the shell and electrically connected to the sub-controller, and a connecting seat arranged on the shell and electrically connected to the sub-controller, the shell and the rotating belt are both provided with a light-transmitting port for irradiating sunlight onto the photovoltaic panel, the shell is provided with a dust discharge port on one side away from the light-transmitting port and close to any rotating roller, the two ends of the rotating belt in the rotation direction are in contact with the light-transmitting port, and the outer surface of the rotating belt located at the light-transmitting port is in contact with the outer surface of the shell, the plurality of dust removal strips are arranged along the movement direction of the rotating belt and can be tightly pressed against the battery panel of the photovoltaic panel, and the connecting seat is used to be electrically connected to the connecting head.

[0013] By adopting the above technical solution, when using the photovoltaic system, the shell is first installed on the horizontal frame and the dust outlet of the shell is located at the inclined lower end of the shell, and then the minimum value of the photoelectric conversion power is set according to the installation situation of the photovoltaic system; when the photoelectric conversion power of the photovoltaic system is lower than the minimum set value, the sub-controller can monitor the photoelectric conversion power of the photovoltaic panel, and then issue a command to the drive motor so that the drive motor drives the corresponding rotating roller to rotate, and the rotating belt operates under the action of the two rotating shaft rollers. The dust removal strip on the rotating belt rotates with it and scrapes the dust off the battery panel on the photovoltaic panel. Under the action of gravity, the dust falls to the bottom of the shell through the light-transmitting port on the rotating belt, and the dust slides downward along the inclined plate of the shell and falls out of the shell through the dust outlet, thereby completing the cleaning of the photovoltaic panel; when encountering thunderstorms or snowfall, the main controller issues a command to the sub-controller, and the sub-controller The driving motor is controlled to operate so that the driving motor drives the corresponding rotating roller to rotate, and the rotating belt runs under the action of the two rotating shaft rollers. The dust removal strip on the rotating belt rotates with it, and stops moving after the rotating belt completely blocks the photovoltaic panel. At this time, the rotating belt seals the light-transmitting port on the shell, and the dust removal strip on the rotating belt is supported on the photovoltaic panel, which can block foreign objects. When foreign objects accumulate on the rotating belt, the rotating belt and the dust removal strip effectively block the foreign objects outside the light-transmitting port, thereby effectively protecting the photovoltaic panel; when the photovoltaic panel is damaged, the photoelectric conversion power of the photovoltaic panel is reduced, and the sub-controller controls the driving motor to drive the rotating belt and the dust removal strip to rotate, and performs a dust removal process on the photovoltaic panel. If there is still no improvement after multiple dust removal processes, the sub-controller transmits the corresponding photovoltaic system information to the main controller, and the main controller transmits the information to the control terminal and issues a warning.

[0014] Preferably, the sub-controller comprises a main control chip, a power detection module electrically connected to the main control chip and used for detecting the power of the photovoltaic panel, and a motor controller electrically connected to the main control chip and used for controlling the operation of the drive motor.

[0015] By adopting the above technical solution, when the photovoltaic panel transmits electric energy to the sub-controller, the power detection module can monitor the photoelectric conversion power of the photovoltaic panel, and then the power detection module transmits the monitored information to the main control chip, which will determine whether to issue instructions to the motor controller after processing; when it is necessary to start the dust removal process of the photovoltaic system, the main control chip issues instructions to the motor controller, and the electronic controller issues instructions to the drive motor to operate; when the power detection module monitors the photovoltaic panel's photoelectric conversion power for a long time and the photovoltaic system has not improved after performing the dust removal process for many times, the main control chip transmits the relevant information to the main controller, and the main controller transmits the corresponding photovoltaic system information to the control terminal.

[0016] Preferably, the housing is provided with a warning light electrically connected to the sub-controller.

[0017] By adopting the above technical solution, when the power detection module monitors the photovoltaic panel photoelectric conversion power for a long time and the photovoltaic system has not improved after performing the dust removal process for many times, the main control chip sends a command to the warning light, so that the corresponding photovoltaic system will sound an alarm through the warning light, which effectively enables maintenance personnel to quickly and accurately find the photovoltaic system that needs maintenance when repairing the photovoltaic system.

[0018] Preferably, the photovoltaic system is provided with a plurality of locking structures for fixing the photovoltaic system on the horizontal frame, the locking structures include a rotating rod slidably arranged on the photovoltaic system, a force block arranged at the end of the rotating rod away from the horizontal frame, a clamping block arranged at the end of the rotating rod close to the horizontal frame, and a reset spring which is sleeved on the rotating rod and always applies a force to the rotating rod toward one end of the force block, the clamping block is a clamping plate with a triangular cross-section, and one of the tips of the clamping block is away from the rotating rod, and the two ends of the reset spring are respectively pressed against the force block and the photovoltaic system.

[0019] By adopting the above technical solution, when installing the photovoltaic system, align the locking structure on the photovoltaic system with the installation slot on the cross frame, and then rotate the force block, which drives the clamping block to rotate through the rotating rod. When the clamping block is rotated to be inserted into the installation slot, the force block is pressed to pass the rotating rod and the clamping block through the installation slot. At this time, the reset spring is further compressed. After the clamping block passes through the installation slot, rotate and release the force block again. Under the action of the reset spring, the clamping block is pressed against the cross frame together with the clamping block, thereby fixing the photovoltaic system on the cross frame.

[0020] Preferably, in the present invention, a surface of the clamping block that contacts the horizontal frame is frosted.

[0021] By adopting the above technical solution, the side of the clamping block that fits the cross frame is frosted, which can enhance the friction between the clamping block and the cross frame and prevent the clamping block and the cross frame from rotating.

[0022] Preferably, the master controller includes a casing, a main control board arranged in the casing, an inverter arranged on the main control board and connected to the house power grid, and an Internet of Things module arranged on the main control board.

[0023] By adopting the above technical solution, the photovoltaic system is electrically connected to the main control board through a connector, and the inverter is connected to the house power grid.

[0025] By adopting the above technical solution, when the terminal time and space are controlled, the photovoltaic system can be shut down through the emergency automatic switch.

[0026] In summary, the present invention has the following advantages:

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] An intelligent solar building roof, such as Figure 1 , 2 As shown, it includes: a support frame, a photovoltaic system, a connector 3, and a master controller 4. The support frame is installed on the roof and consists of a plurality of vertical frames 1 and a plurality of horizontal frames 2. The horizontal frames 2 are provided with installation grooves for installing the photovoltaic system, the connector 3 and the master controller 4; the photovoltaic system is installed on the horizontal frames 2, is used for photoelectric conversion, and has the functions of automatic cleaning and protection; the connector is installed on the horizontal frames 2, consists of a connector 3 and a connecting line, and is useful for connecting a plurality of photovoltaic systems together; the master controller 4 is installed on the support frame, is used for summarizing and controlling the operating conditions of a plurality of photovoltaic systems and is connected to the house power grid, and has an Internet of Things module connected to the control terminal signal.

[0038] Among them, Figure 2 , 3As shown, the photovoltaic system includes a housing 5 installed on the horizontal frame 2, a photovoltaic panel 6 installed in the housing 5 and used to receive solar energy, two rotating rollers 7 installed in the housing 5 and respectively located at the corresponding ends of the photovoltaic panel 6, a rotating belt 8 installed on the two rotating rollers 7 and tightened between the two rotating rollers 7, a plurality of dust removal strips 9 installed on the side of the rotating belt 8 facing the photovoltaic panel 6 and used to clean dust on the photovoltaic panel 6, a driving motor 10 installed in the housing 5 and the rotating shaft is connected to the rotating roller 7 at the inclined lower end, a sub-controller 11 installed in the housing 5 and electrically connected to the photovoltaic panel 6, a storage battery 12 installed in the housing 5 and electrically connected to the sub-controller 11, and a power supply 12 installed on the housing 5. A connecting seat 13 is electrically connected to the sub-controller 11, and a light-transmitting port 14 for sunlight to irradiate the photovoltaic panel 6 is installed on the shell 5 and the rotating belt 8. A dust discharge port 15 is provided on the shell 5 away from the light-transmitting port 14 and close to any rotating roller 7. Both ends of the rotating belt 8 in the rotation direction are in contact with the light-transmitting port 14 and the outer surface of the rotating belt 8 at the light-transmitting port 14 is in contact with the outer surface of the shell 5. A plurality of dust removal strips 9 are arranged along the movement direction of the rotating belt 8 and can be tightly pressed against the battery panel of the photovoltaic panel 6, and the extension direction of the dust removal strips 9 is perpendicular to the movement direction of the rotating belt 8. The driving motor 10 is a stepping motor, and the connecting seat 13 is used to be electrically connected to the connector 3.

[0039] When using the photovoltaic system, the shell 5 is first installed on the horizontal frame 2 and the dust outlet 15 of the shell 5 is located at the inclined lower end of the shell 5, and then the minimum value of the photoelectric conversion power is set according to the installation situation of the photovoltaic system; when the photoelectric conversion power of the photovoltaic system is lower than the minimum set value, the sub-controller 11 can monitor the photoelectric conversion power of the photovoltaic panel 6, and then issue a command to the drive motor 10, so that the drive motor 10 drives the corresponding rotating roller 7 to rotate, and the rotating belt 8 is operated under the action of the two rotating shaft rollers. The dust removal strip 9 on the rotating belt 8 follows its rotation and scrapes the dust off the battery panel on the photovoltaic panel 6. Under the action of gravity, the dust falls to the bottom of the shell 5 through the light-transmitting port 14 on the rotating belt 8, and the dust slides downward along the inclined plate of the shell 5 and falls out of the shell 5 through the dust outlet 15, and the cleaning of the photovoltaic panel 6 is completed; when encountering thunderstorms or snowy days, the main controller 4 issues a command to the sub-controller 11, and the sub-controller 11 controls the drive motor 10. The control operation makes the driving motor 10 drive the corresponding rotating roller 7 to rotate, and the rotating belt 8 runs under the action of the two rotating shaft rollers. The dust removal strip 9 on the rotating belt 8 rotates with it, and stops moving after the rotating belt 8 completely blocks the photovoltaic panel 6. At this time, the rotating belt 8 seals the light-transmitting opening 14 on the shell 5, and the dust removal strip 9 on the rotating belt 8 is supported on the photovoltaic panel 6, which can block foreign objects. When foreign objects accumulate on the rotating belt 8, the rotating belt 8 and the dust removal strip 9 effectively block the foreign objects outside the light-transmitting opening 14, thereby effectively protecting the photovoltaic panel 6; when the photovoltaic panel 6 is damaged, the photoelectric conversion power of the photovoltaic panel 6 is reduced, and the sub-controller 11 controls the driving motor 10 to drive the rotating belt 8 and the dust removal strip 9 to rotate, and performs a dust removal process on the photovoltaic panel 6. After multiple dust removal processes, there is still no improvement. At this moment, the sub-controller 11 transmits the corresponding photovoltaic system information to the main controller 4, and the main controller 4 transmits the information to the control terminal and issues a warning.

[0040] like Figure 4 As shown, the sub-controller 11 includes a main control chip, a power detection module electrically connected to the main control chip and used to detect the power of the photovoltaic panel 6, and a motor controller electrically connected to the main control chip and used to control the operation of the drive motor 10, and the motor controller is a stepper motor controller. When the photovoltaic panel 6 transmits electric energy to the sub-controller 11, the power detection module can monitor the photoelectric conversion power of the photovoltaic panel 6, and then the power detection module transmits the monitored information to the main control chip, which will determine whether to issue instructions to the motor controller after processing; when it is necessary to start the dust removal process of the photovoltaic system, the main control chip issues instructions to the motor controller, and the electronic controller issues instructions to the drive motor 10 to operate; when the power detection module monitors the low photoelectric conversion power of the photovoltaic panel 6 for a long time and the photovoltaic system performs the dust removal process for many times and still has no improvement, the main control chip transmits the relevant information to the main controller 4, and the main controller 4 transmits the corresponding photovoltaic system information to the control terminal.

[0041] Further, such as Figure 1 As shown, a warning light 16 electrically connected to the sub-controller 11 is installed on the outer surface of the housing 5. When the power detection module monitors that the photoelectric conversion power of the photovoltaic panel 6 is low for a long time and the photovoltaic system performs the dust removal process for many times without improvement, the main control chip sends a command to the warning light 16, so that the corresponding photovoltaic system sends an alarm through the warning light 16, which effectively enables maintenance personnel to quickly and accurately find the photovoltaic system that needs maintenance when repairing the photovoltaic system.

[0042] like Figure 2 , 3 As shown, the photovoltaic system is equipped with a number of locking structures for fixing the photovoltaic system on the horizontal frame 2, the locking structures include a rotating rod 17 slidably installed on the photovoltaic system, a force block 18 installed at the end of the rotating rod 17 away from the horizontal frame 2, a clamping block 19 installed at the end of the rotating rod 17 close to the horizontal frame 2, and a return spring which is sleeved on the rotating rod 17 and always applies a force to the rotating rod 17 toward one end of the force block 18, the clamping block 19 is a clamping plate with a triangular cross-section, and one of the tips of the clamping block 19 is away from the rotating rod 17, and the two ends of the return spring are respectively pressed against the force block 18 and the photovoltaic system.

[0043] When installing the photovoltaic system, align the locking structure on the photovoltaic system with the installation groove on the cross frame 2, and then rotate the force block 18. The force block 18 drives the clamping block 19 to rotate through the rotating rod 17. When the clamping block 19 is rotated to be inserted into the installation groove, the force block 18 is pressed to pass the rotating rod 17 and the clamping block 19 through the installation groove. At this time, the reset spring is further compressed. When the clamping block 19 passes through the installation groove, the force block 18 is rotated again and released. The clamping block 19 is pressed against the cross frame 2 under the action of the reset spring, thereby fixing the photovoltaic system on the cross frame 2.

[0044] Furthermore, the surface of the clamping block 19 that contacts the cross frame 2 is frosted, which can enhance the friction between the clamping block 19 and the cross frame 2 and prevent the clamping block 19 and the cross frame 2 from rotating.

[0045] like Figure 5 As shown, the master controller 4 includes a housing, a main control board installed in the housing, an inverter installed on the main control board and connected to the house power grid, and an Internet of Things module installed on the main control board. The photovoltaic system is electrically connected to the main control board through a connector, and the inverter is connected to the house power grid. When the photovoltaic system converts photoelectricity and transmits it to the main control board, the main control board converts direct current through the inverter and transmits it to the house power grid; when the photovoltaic system needs to be monitored, the Internet of Things module on the main control board and the external control terminal collect information and issue instructions.

[0046] It is worth mentioning that the main control panel is equipped with an emergency brake switch that is electrically connected to it and extends into the house. When the control terminal is in time and space, the photovoltaic system can be shut down through the emergency automatic switch.

[0047] The working process and beneficial effects of the present invention are as follows: before using the solar building roof, the support frame can be first fixed on the roof of the house, so that a number of vertical frames 1 are used to support a number of horizontal frames 2, and then the photovoltaic system is installed on the horizontal frame 2 and closely arranged along the horizontal frame 2, and then the photovoltaic systems are connected to the main controller 4 through the connector 3; when using solar power generation, the photovoltaic system can convert solar energy into electrical energy and summarize it to the main controller 4 through the connector 3, and each photovoltaic system transmits its related work operation information to the main controller 4; when any photovoltaic system has a reduced power generation power due to dust accumulation, its corresponding internal monitoring and start the dust cleaning device on the photovoltaic system to clean the photovoltaic system; When encountering thunderstorms or snowfall, the control terminal and the local weather monitoring equipment collect information and transmit the information to the main controller 4 through the Internet of Things module, so that the main controller 4 transmits the instruction to each photovoltaic system through the connector 3. After receiving the instruction, the photovoltaic system starts the protective measures to protect the photovoltaic system; when any photovoltaic system is damaged and the photoelectric conversion power is lower than the average value for a long time, the photovoltaic system will be optimized through its own dust removal process, and if there is still no improvement after the dust removal process is optimized, the corresponding photovoltaic system will send its position to the main controller 4, and then the main controller 4 will transmit the relevant position information of the damaged photovoltaic system to the control terminal through the Internet of Things module.

[0048] In summary, the photovoltaic system, the connector 3 and the main controller 4 are controlled by the support frame, and then the photovoltaic system performs photoelectric conversion and performs dust removal through self-monitoring. The main controller 4 monitors the weather through the control terminal and issues instructions to the photovoltaic system to protect itself, thereby achieving intelligent positioning, point warning, and maintenance, automatic adjustment to clean the dust on the photovoltaic panel 6, and having the effect of extending the service life of the photovoltaic panel 6.

[0049] 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 design concept of the present invention should be included in the protection scope of the present invention.
