Description

Technical Field

[0001] The present invention relates to the field of photovoltaic modules, and in particular to an energy storage device and electrical equipment. Background Art

[0002] The working principle of solar panels is mainly based on the photoelectric effect (also known as the photovoltaic effect), which reveals the conversion mechanism between light energy and electrical energy. When light (especially sunlight) shines on the surface of certain materials (such as semiconductors such as silicon), photons (particles of light) interact with atoms or electrons in the material. If the energy of the photons is large enough, it can excite the electrons in the atoms to form free electrons, which in turn generates an electric current in the material. In this process, light energy is converted into electrical energy. Therefore, solar panels have become one of the main energy storage devices.

The energy storage device has limited energy collection positions and a single module. When it is necessary to determine the optimal tilt angle based on comprehensive consideration of multiple factors such as geographical location, season, weather, and installation environment, it is impossible to make targeted adjustments to a certain solar photovoltaic panel, which in turn affects the solar light absorption rate and power generation efficiency.

[0029] Embodiment 1

[0030] like Figure 1-Figure 2 As shown, an energy storage device proposed in the present invention includes an installation frame, which is a frame body composed of installation boxes 1 on left and right sides and crossbeams 2 on upper and lower sides; multiple groups of photovoltaic modules are movably arranged on the installation frame, and the spacing and working angles are adjustable; solar energy control equipment and electric energy storage and conversion equipment are arranged on the installation box 1 to assist the operation of each photovoltaic module.

[0031] A light sensor 7 is disposed on the crossbeam 2 to sense light intensity and angle.

[0032] The photovoltaic module includes a mounting frame 1 3 which can move horizontally and rotate along the beam 2; a mounting frame 2 5 is flipped and arranged at the front side of the mounting frame 1 3; and the solar panel 4 and the cleaning component 6 are both installed at the front end of the mounting frame 2 5.

[0033] The cleaning assembly 6 includes a pushing member 601 located above the solar panel 4, a resetting member 602 located below the solar panel 4, and a cleaning member 603 located between the pushing member 601 and the resetting member 602; the cleaning member 603 reciprocates under the jet of the pushing member 601 and the adsorption of the resetting member 602 to clean the end surface of the solar panel 4.

[0034] like Figure 1-Figure 5 As shown, a plurality of light sensors 7 and tracks are arranged on the crossbeam 2 along the length direction; a driving member for driving the mounting frame 3 to move horizontally and rotate is arranged in the track.

[0035] Multiple groups of light sensors 7 can detect the light intensity and angle at different positions, so as to adjust the solar panels 4 in a targeted manner to obtain a maximized energy storage source;

[0036] It should be further explained that the driving member includes a lead screw 9 driven by a motor 1 and rotating on the track; the moving block 8 is threadedly connected to the lead screw 9 to achieve horizontal movement along the track; the rotating shaft 11 is driven by a motor 2, one end of which rotates on the moving block 8 and the other end is connected to a mounting frame 3; the movement and rotation of the mounting frame 3 can drive the solar panel 4 to move synchronously and adjust its position and angle to match the detection result of the light sensor 7.

[0037] It should be further explained that the mounting frame 1 3 is a cover structure with an opening at the front end, and the upper and lower ends are respectively connected to the corresponding rotating shafts 11. The mounting frame 2 5 is a plate body with a slot set at the front end, driven by the motor 3 10, the upper end is rotated to connect to the top of the cover of the mounting frame 1 3, and the lower end is suspended; the solar cell panel 4 is embedded in the slot of the mounting frame 2 5.

[0038] By rotating the mounting frame 2 5 on the mounting frame 1 3, the solar panel 4 is turned outward to adjust the angle of the solar panel 4. The angle between the solar panel and the light, that is, the tilt angle of the solar panel, will directly affect its power generation efficiency. In order to maximize the absorption of sunlight and improve the power generation efficiency, it is necessary to comprehensively consider multiple factors such as geographical location, season, weather and installation environment to determine the optimal tilt angle. In the present invention, the solar panel 4 is arranged to move and rotate to adapt to the changes in the solar altitude angle under different seasons and weather conditions, so as to obtain the maximum solar energy irradiation effect.

[0039] like Figure 6 As shown, a vent 501 and a mounting groove 502 are provided on the mounting frame 2 5; a support rod 13 is provided between the mounting frame 2 5 and the mounting frame 1 3; the lower end of the support rod 13 is rotatably connected to a slider, and the upper end is rotatably connected to a fixing block. The slider is slidably connected to the groove wall of the mounting groove 502; and the fixing block is located on the mounting frame 1 3.

[0040] When the second mounting frame 5 is flipped, the support rod 13 slides and rotates synchronously to provide support for the second mounting frame 5 to maintain the stability of the solar cell panel 4.

[0041] like Figure 3 , Figure 4 and Figure 7 As shown, the pusher 601 includes an air pump box 60101; the air pump box 60101 is arranged through the top of the mounting frame 5, and has a built-in air pump group and a pressurizing device that cooperate with each other; the air nozzle 60102 is arranged at the front end of the air pump box 60101, and is connected to the air outlet end of the air pump group to spray air downward; the air inlet nozzle 60103 is arranged at the rear end of the air pump box 60101, and is connected to the air inlet end of the air pump group to take in air downward.

[0042] As the solar panel 4 works, the ventilation behind the mounting frame 2 5 is poor, and heat is not easy to dissipate. Through the cooperation of the air pump group and the pressurizing device, on the one hand, the air inlet nozzle 60103 sucks the air behind the mounting frame 2 5 to accelerate the heat dissipation, and on the other hand, the air nozzle 60102 provides a driving force by jetting downward to drive the cleaning member 603 to move.

[0043] The reset member 602 is a horizontally arranged bar-shaped electromagnet; the electromagnet can generate an adsorption force when powered on to attract the cleaning member 603 .

[0044] Hollow guide strips 604 are arranged on both sides of the corresponding slots on the mounting frame 2 5; two groups of guide strips 604 are arranged in parallel on both sides of the solar cell panel 4, and guide openings 60401 are arranged on the opposite ends along the length direction; the cleaning member 603 includes a cleaning frame 60301 arranged between the two groups of guide strips 604; a rotatable cleaning roller brush 60303 is arranged on the cleaning frame 60301; rotating rods that rotate and penetrate the guide openings 60401 are arranged at both ends of the cleaning roller brush 60303; an elastic torsion spring sheet 60304 is sleeved on the rotating rod, the inner end of which is connected to the side wall of the rotating rod, and the outer end is connected to the top of the guide strip 604.

[0045] It should be further explained that the cleaning frame 60301 is a semi-columnar structure, with the cleaning frames 60301 on both sides being slidably connected. The flat side opening is for the installation of the cleaning roller brush 60303. The upper end of the convex side is provided with a windward surface that cooperates with the air nozzle 60102, and the lower end of the convex side is provided with a metal strip 60302 that cooperates with the electromagnet.

[0046] When the air nozzle 60102 sprays gas downward to the windward side of the cleaning frame 60301, it not only generates a downward thrust, but also has the effect of air supply and cleaning. The cleaning roller brush 60303 moves downward and rolls to clean the solar panel 4. During the descent of the cleaning frame 60301, the elastic torsion spring sheet 60304 is stretched. The electromagnet is energized to adsorb the metal strip 60302, which helps the cleaning frame 60301 to descend. The cleaning frame 60301 stops at the electromagnet, and the elastic torsion spring sheet 60304 is stretched to the limit. The stillness at this time has the effect of accumulating power. The electromagnet is powered off, the air nozzle 60102 stops spraying, and the elastic torsion spring sheet 60304 rebounds, driving the cleaning frame 60301 to move up and reset. The reciprocating movement of the cleaning roller brush 60303 up and down for cleaning is achieved through the repeated cooperation of the air nozzle 60102 and the electromagnet.

[0047] like Figure 8-Figure 9 As shown, a circle of inflatable and deflable sealed airbags 12 are arranged along the cover opening of the mounting frame 3; the air pump group is connected to the air injection nozzle 60102 and the air inlet nozzle 60103, and at the same time, is connected to the sealed airbag 12.

[0048] When lightning occurs, two adjacent groups of mounting frames 3 rotate until the solar panels 4 are opposite and close to each other, and then the two groups of sealing airbags 12 are inflated until they fit together, forming a sealed environment to protect the solar panels 4 and reduce damage to the solar panels 4 caused by severe weather.

[0049] It should be further explained that a lightning sensor is provided on the crossbeam 2 to assist the device in making judgments on severe weather conditions.

[0050] Embodiment 2

[0051] This embodiment is based on the energy storage device in the first embodiment and proposes a working method of the energy storage device. Taking two groups of photovoltaic modules as an example, the working steps are as follows:

[0052] S1, light sensor 7 and lightning sensor monitor the working environment;

[0053] S2.

[0054] S3, when thunderstorm weather is detected, two adjacent groups of mounting frames 3 are rotated until the solar panels 4 are opposite and close to each other, and then two groups of sealing airbags 12 are inflated until they fit together, forming a sealed environment to protect the solar panels 4;

[0055] S4, regularly start the air pump group and the pressurizing device, the air inlet nozzle 60103 sucks the air behind the mounting frame 2 5 to accelerate the heat removal, and the air nozzle 60102 provides a driving force by spraying air downward to drive the cleaning member 603 to move;

[0056] S5, when the air nozzle 60102 sprays gas downward to the windward side of the cleaning frame 60301, the cleaning roller brush 60303 moves downward and rolls to clean the solar cell panel 4;

[0057] S6, while the cleaning rack 60301 descends, the elastic torsion spring 60304 is stretched; the electromagnet attracts the metal strip 60302 to assist the cleaning rack 60301 in descending;

[0058] S7, the cleaning frame 60301 stops at the electromagnet, and the elastic torsion spring 60304 is stretched to the limit;

[0059] S8, the electromagnet is powered off, the air nozzle 60102 stops air jetting, the elastic torsion spring 60304 rebounds, and drives the cleaning frame 60301 to move upward and reset;

[0060] S9, the cleaning roller brush 60303 moves back and forth up and down for cleaning.
