Description

Technical Field

[0001] This invention belongs to the field of energy-saving device technology, specifically a wind-solar hybrid energy-saving device for buildings and its working method. Background Technology

[0002] A wind-solar hybrid energy-saving device is a power generation system that combines two renewable energy sources, wind and solar energy, and aims to optimize energy supply and improve energy efficiency through complementarity.

[0003] A search revealed a patent, CN215759312U, for an intelligent building structure energy-saving device. This device includes a roof and walls. An annular base is mounted on the upper surface of the roof. A tower is fixedly connected to the inner wall of the annular base. One end of the tower is fixedly connected to a connecting shaft, and one end of the connecting shaft is fixedly connected to a nacelle. A wind turbine is rotatably connected to one end of the nacelle. A bracket is fixedly connected to one side of the upper surface of the roof, and a solar panel is fixedly connected to the top of the bracket. This intelligent building structure energy-saving device, through the arrangement of the wind turbine and solar panels, allows the solar panels to absorb solar energy and convert it into electricity on sunny days. On cloudy or rainy days, the wind turbine's rotation converts kinetic energy into electricity, avoiding the problem of a single energy-absorbing device being unable to provide power under special circumstances. The generated electricity meets the power needs of each module.

[0004] Current energy-saving devices are generally installed on the top surface of buildings, directly exposed to the external environment. They inevitably come into contact with various tiny particles in the air. Over time, these particles, including dust, resin, and other airborne droplets, gradually accumulate on the surface of the solar panels, causing a significant decrease in the ability of the panels to reflect and absorb sunlight, affecting power generation efficiency, and consequently affecting the energy conversion of the entire energy-saving system. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving device for building wind-solar hybrid systems and its operating method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving device for building wind-solar hybrid systems, comprising a roof, a wind turbine generator and a mounting base installed at the top of the roof, a maintenance plate provided at the top of the mounting base, solar panels installed on both sides of the mounting base, a cleaning component provided at the top of each of the two solar panels, and a wind-solar hybrid controller and a battery installed at the bottom of the roof.

[0007] The cleaning assembly includes a cleaning plate disposed at the top of the solar panel, an auxiliary cleaning component disposed inside the cleaning plate, a second cleaning cloth mounted at the top of the cleaning plate, a first cleaning cloth mounted at the bottom of the cleaning plate, a movable block connected to one end of the cleaning plate via a rotating component, the movable block being slidably mounted inside the mounting base, a threaded rod being threadedly connected inside the movable block, a motor being mounted at one end of the threaded rod, and the motor being disposed inside the mounting base.

[0008] As a further technical solution of the present invention, the auxiliary cleaning component includes water outlet holes opened inside the cleaning plate, the water outlet holes are evenly arranged, one end of the cleaning plate is connected to a water pipe, the water pipe is embedded inside the movable block, the water pipe passes through the inside of the movable block and extends to the inner wall of the mounting base, and a water pump is installed on the outer wall of the water pipe.

[0009] As a further technical solution of the present invention, the inner wall of the inspection plate is provided with filter holes, and the filter holes are evenly distributed.

[0010] As a further technical solution of the present invention, the inspection plate is installed on the top of the mounting base by bolts.

[0011] As a further technical solution of the present invention, a filter screen is installed inside the mounting base, and the filter screen is located below the inspection plate.

[0012] As a further technical solution of the present invention, the rotating assembly includes a first rotating shaft fixedly installed at one end of the cleaning plate. The first rotating shaft is rotatably installed inside the moving block. A gear is fixedly connected to the outer wall of the first rotating shaft. A toothed block is meshed at the bottom end of the gear. The toothed block is evenly arranged at the top of the fixed plate. The fixed plate is fixedly installed on one side of the mounting base.

[0013] As a further technical solution of the present invention, a second rotating shaft is fixedly installed on both sides of the tooth block, and the second rotating shaft is rotatably installed inside the fixed plate.

[0014] As a further technical solution of the present invention, a torsion spring is installed on the outer wall of the second rotating shaft, and the torsion spring is disposed on the inner wall of the fixed plate.

[0015] As a further technical solution of the present invention, side baffles are installed at the bottom ends of both sides of the inspection plate, and the side baffles are set at the top of the solar panel.

[0016] A method for operating a wind-solar hybrid energy-saving device for buildings includes the following steps:

[0017] S1: When it is necessary to clean the surface of the solar panel, the motor is started by controlling the PLC. The start of the motor drives the screw rod to rotate, the rotation of the screw rod drives the moving block to move, the movement of the moving block drives the cleaning plate to move, and the movement of the cleaning plate drives the first cleaning cloth to move back and forth on the surface of the solar panel to clean the surface of the solar panel.

[0018] S2: Simultaneously start the water pump to draw water from inside the mounting base to the inside of the cleaning plate through the water pipe, and finally discharge it from the water outlet. The water is then absorbed by the first cleaning cloth and used to clean the surface of the solar panel.

[0019] S3: When the moving block moves outside the fixed plate, the gear moves and meshes with the gear block to rotate. The rotation of the gear drives the rotation of the first rotating shaft. The rotation of the first rotating shaft causes the cleaning plate to rotate 180 degrees, so that the second cleaning cloth rotates to the bottom and contacts the surface of the solar panel, wiping the water stains on the surface of the solar panel. Finally, it is retracted to one side of the side baffle to complete the cleaning.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention, through the configuration of a cleaning component, activates a motor controlled by a PLC when cleaning of the solar panel surface is required. The motor's activation drives the rotation of a threaded rod, which in turn moves a moving block. This movement of the moving block, in turn, moves a cleaning plate. The cleaning plate then causes a first cleaning cloth to reciprocate across the surface of the solar panel, cleaning its surface. This prevents dust from gradually accumulating on the solar panel surface, which would significantly reduce its ability to reflect and absorb sunlight, thus affecting power generation efficiency and consequently impacting the energy conversion of the entire energy-saving system. Cleaning the solar panel improves its power generation efficiency and extends its lifespan.

[0022] This invention improves the cleaning effect by setting up an auxiliary cleaning component. When cleaning the surface of the solar panel, a water pump is activated to draw water from inside the mounting base through a water pipe to the inside of the cleaning panel, and finally discharges it from the water outlet. The water is then absorbed by the first cleaning cloth before cleaning the surface of the solar panel.

[0023] This invention, through the setting of a rotating component, when the moving block moves outside the fixed plate, the gear moves and meshes with the gear block to rotate. The rotation of the gear drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft causes the cleaning plate to rotate 180 degrees, so that the second cleaning cloth rotates to the bottom and contacts the surface of the solar panel, wiping the water stains on the surface of the solar panel, ensuring that the surface of the solar panel is clean and transparent, and improving the light transmittance and photoelectric conversion efficiency.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown in the embodiment of the present invention, an energy-saving device for building wind-solar hybrid power generation includes a roof 1, a wind turbine generator 2 and a mounting base 3 installed at the top of the roof 1, a maintenance plate 7 provided at the top of the mounting base 3, solar panels 4 installed on both sides of the mounting base 3, a cleaning component provided at the top of each of the two solar panels 4, and a wind-solar hybrid controller 5 and a battery 6 installed at the bottom of the roof 1.

[0033] The cleaning component includes a cleaning plate 11 disposed at the top of the solar panel 4. An auxiliary cleaning component is disposed inside the cleaning plate 11. A second cleaning cloth 19 is installed at the top of the cleaning plate 11, and a first cleaning cloth 12 is installed at the bottom of the cleaning plate 11. A moving block 13 is connected to one end of the cleaning plate 11 through a rotating component. The moving block 13 is slidably installed inside the mounting base 3. A threaded rod 15 is threadedly connected inside the moving block 13. A motor 14 is installed at one end of the threaded rod 15. The motor 14 is disposed inside the mounting base 3.

[0034] The existing patent CN215759312U discloses an intelligent building structure energy-saving device. This patent discloses the roof 1, wind turbine generator 2, solar panel 4, wind-solar hybrid controller 5 and battery 6 proposed in this application. The technical means are not described in detail here.

[0035] When the surface of the solar panel 4 needs to be cleaned, the motor 14 is started by the PLC control. The start of the motor 14 drives the rotation of the threaded rod 15, which in turn drives the moving block 13 to move. The movement of the moving block 13 drives the cleaning plate 11 to move, and the movement of the cleaning plate 11 drives the first cleaning cloth 12 to move back and forth on the surface of the solar panel 4 to clean the surface of the solar panel 4. This prevents dust in the air from gradually accumulating on the surface of the solar panel 4, which would significantly reduce the ability of the solar panel 4 to reflect and absorb sunlight, affecting the power generation efficiency and thus affecting the energy conversion of the entire energy-saving system. Cleaning the solar panel 4 can improve its power generation efficiency and extend its service life.

[0036] like Figures 1 to 5 As shown, the auxiliary cleaning component includes water outlet holes 18 opened inside the cleaning plate 11. The water outlet holes 18 are evenly arranged. One end of the cleaning plate 11 is connected to a water pipe 17. The water pipe 17 is embedded inside the movable block 13. The water pipe 17 passes through the interior of the movable block 13 and extends to the inner wall of the mounting base 3. A water pump 16 is installed on the outer wall of the water pipe 17.

[0037] The first cleaning cloth 12 and the second cleaning cloth 19 are made of soft cloth or sponge and have a certain degree of water absorption.

[0038] When cleaning the surface of the solar panel 4, the water pump 16 is started, and water is drawn from the inside of the mounting base 3 through the water pipe 17 into the inside of the cleaning plate 11. Finally, the water is discharged from the water outlet 18 and absorbed by the first cleaning cloth 12 before cleaning the surface of the solar panel 4, thereby improving the cleaning effect.

[0039] It is recommended to clean the solar panels on a sunny day or when the sunlight intensity is not high to minimize the impact on the solar panels.

[0040] like Figures 1 to 3As shown, the inner wall of the inspection plate 7 is provided with filter holes 26, which are evenly distributed.

[0041] With the installation of the inspection plate 7, rainwater is filtered through the inspection plate 7 and collected into the mounting base 3 for storage during rainy days, thus saving water resources.

[0042] like Figures 1 to 3 As shown, the inspection plate 7 is mounted on the top of the mounting base 3 by bolts 8.

[0043] Remove the inspection plate 7 using bolt 8 for easy maintenance.

[0044] like Figure 3 As shown, a filter screen 10 is installed inside the mounting base 3, and the filter screen 10 is located below the inspection plate 7.

[0045] The collected rainwater is filtered again to improve its cleanliness.

[0046] like Figures 1 to 6 As shown, the rotating assembly includes a first rotating shaft 20 fixedly installed at one end of the cleaning plate 11. The first rotating shaft 20 is rotatably installed inside the moving block 13. A gear 21 is fixedly connected to the outer wall of the first rotating shaft 20. A toothed block 23 is meshed at the bottom end of the gear 21. The toothed blocks 23 are evenly arranged at the top of the fixed plate 22. The fixed plate 22 is fixedly installed on one side of the mounting base 3.

[0047] When the moving block 13 moves outside the fixed plate 22, the gear 21 moves and meshes with the toothed block 23 to rotate. The rotation of the gear 21 drives the rotation of the first rotating shaft 20. The rotation of the first rotating shaft 20 causes the cleaning plate 11 to rotate 180 degrees, so that the second cleaning cloth 19 rotates to the bottom and contacts the surface of the solar panel 4, wiping the water stains on the surface of the solar panel 4, ensuring that the surface of the solar panel 4 is clean and transparent, and improving the light transmittance and photoelectric conversion efficiency.

[0048] like Figure 6 As shown, a second rotating shaft 24 is fixedly installed on both sides of the toothed block 23, and the second rotating shaft 24 is rotatably installed inside the fixed plate 22.

[0049] The toothed block 23 is tilted on one side;

[0050] The inside of the fixing plate 22 is provided with a groove for the toothed block 23 to slide into;

[0051] When the moving block 13 moves to one side of the mounting base 3, the movement of the moving block 13 drives the movement of the gear 21. The movement of the gear 21 contacts the tooth block 23, forcing the tooth block 23 to rotate around the second rotating shaft 24. The tooth block 23 rotates into the groove inside the fixed plate 22, so that the gear 21 does not rotate, thus making the cleaning plate 11 rotate only once for each reciprocating movement.

[0052] like Figure 6 As shown, a torsion spring 25 is installed on the outer wall of the second rotating shaft 24, and the torsion spring 25 is disposed on the inner wall of the fixed plate 22.

[0053] When the toothed block 23 rotates, the second rotating shaft 24 rotates, causing the torsion spring 25 to deform and store elastic potential energy, and then releases the elastic potential energy to reset.

[0054] like Figure 3 As shown, side baffles 9 are installed at the bottom of both sides of the inspection plate 7, and the side baffles 9 are located at the top of the solar panel 4.

[0055] The side baffle 9 is located on one side of the cleaning plate 11. When the device is not in use, the side baffle 9 covers the cleaning plate 11 to prevent dust.

[0056] The side baffle 9 is made of rubber sheet. When the cleaning plate 11 is moved back to the inside of the inspection plate 7, the side baffle 9 deforms and resets to protect the cleaning plate 11.

[0057] A method for operating a wind-solar hybrid energy-saving device for buildings includes the following steps:

[0058] S1: When it is necessary to clean the surface of the solar panel 4, the motor 14 is started by controlling the PLC. The start of the motor 14 drives the rotation of the threaded rod 15. The rotation of the threaded rod 15 drives the moving block 13 to move. The movement of the moving block 13 drives the cleaning plate 11 to move. The movement of the cleaning plate 11 drives the first cleaning cloth 12 to move back and forth on the surface of the solar panel 4 to clean the surface of the solar panel 4.

[0059] S2: Simultaneously start the water pump 16, draw water from the inside of the mounting base 3 through the water pipe 17 to the inside of the cleaning plate 11, and finally discharge it from the water outlet 18. After being absorbed by the first cleaning cloth 12, the surface of the solar panel 4 is cleaned.

[0060] S3: When the moving block 13 moves outside the fixed plate 22, the gear 21 moves and meshes with the tooth block 23 to rotate. The rotation of the gear 21 drives the rotation of the first rotating shaft 20. The rotation of the first rotating shaft 20 drives the cleaning plate 11 to rotate 180 degrees, so that the second cleaning cloth 19 rotates to the bottom and contacts the surface of the solar panel 4, wiping the water stains on the surface of the solar panel 4, and finally retracting to one side of the side baffle 9 to complete the cleaning.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
