Description

Technical Field

[0001] This invention relates to the field of photovoltaic modules, and more particularly to an energy storage device and electrical equipment. Background Technology

[0002] Solar panels operate primarily based on the photoelectric effect (also known as the photovoltaic effect), which reveals the mechanism of converting light energy into electrical energy. When light (especially sunlight) shines on the surface of certain materials (such as semiconductors like silicon), photons (particles of light) interact with atoms or electrons in the material. If the photons have sufficient energy, they can excite electrons in the atoms, creating free electrons and generating an electric current within the material. In this process, light energy is converted into electrical energy. Therefore, solar panels have become one of the main energy storage devices.

[0003] Chinese patent CN219535975U discloses an energy storage device for solar photovoltaic, including a support platform and a solar photovoltaic panel. A baffle is fixedly connected to the top of the connecting frame, and a felt brush and a nozzle are fixedly installed on the bottom surface of the baffle.

[0004] The aforementioned energy storage device has the following shortcomings: Because it rotates as a whole to drive the synchronous rotation of all solar photovoltaic panels, it can only synchronously adjust all panels through overall circular motion. Furthermore, the energy collection locations are limited, and the modules are singular. When determining the optimal tilt angle based on multiple factors such as geographical location, season, weather, and installation environment, it cannot make targeted adjustments to individual solar photovoltaic panels, thus affecting solar absorption rate and power generation efficiency. Summary of the Invention

[0005] To address the problems existing in the background technology, an energy storage device and electrical equipment are proposed. The photovoltaic module moves and rotates independently based on monitoring data to adjust the position of the corresponding solar panel. A pushing and resetting component drives a cleaning component to move back and forth across the end face of the solar panel for cleaning. The pushing component also draws in air from behind the mounting bracket, accelerating heat dissipation. Ultimately, through the combined structure, efficient energy storage and energy conservation are achieved.

[0006] This invention proposes an energy storage device, including a mounting frame, which is a frame body composed of mounting boxes on the left and right sides and crossbeams on the top and bottom sides; multiple sets of photovoltaic modules are movably mounted on the mounting frame, and the spacing and working angle are adjustable.

[0007] The mounting box is equipped with solar control equipment and energy storage and conversion equipment to assist the operation of each photovoltaic module. A light sensor is installed on the crossbeam to detect the intensity and angle of light.

[0008] The photovoltaic module includes a mounting frame 1 that can move horizontally and rotate along a crossbeam; a mounting frame 2 is flipped and positioned in front of the mounting frame 1; the solar panel and the cleaning component are both mounted on the front end of the mounting frame 2; the cleaning component includes a pusher located above the solar panel, a resetter located below the solar panel, and a cleaning component located between the pusher and the resetter; the cleaning component reciprocates under the air jet from the pusher and the suction of the resetter to clean the end face of the solar panel.

[0009] Preferably, multiple light sensors and tracks are arranged along the length of the crossbeam; a drive mounting frame is installed inside the track to drive the horizontal movement and rotation.

[0010] Preferably, mounting frame one is a cover structure with an open front end, and the upper and lower ends are respectively connected to corresponding driving components; mounting frame two is a plate with a slot at the front end, the upper end is rotatably connected to the top of the cover opening of mounting frame one, and the lower end is suspended; the solar panel is embedded in the slot of mounting frame two.

[0011] Preferably, the second mounting bracket is provided with a ventilation opening and a mounting groove; a support rod is provided between the second mounting bracket and the first mounting bracket; the lower end of the support rod 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; the fixing block is located on the first mounting bracket.

[0012] Preferably, the pushing component includes an air pump box; the air pump box is disposed through the top of the mounting frame 2, and contains a mutually cooperating air pump group and pressurization equipment; the air nozzle is disposed at the front end of the air pump box, and sprays air downwards through the air outlet end of the air pump group; the air inlet is disposed at the rear end of the air pump box, and intakes air downwards through the air inlet end of the air pump group.

[0013] Preferably, the reset element is a horizontally arranged strip electromagnet.

[0014] Preferably, hollow guide strips are provided on both sides of the slot on the second mounting bracket; two sets of guide strips are arranged parallel to each other on both sides of the solar panel, and guide openings are provided on the opposite ends along the length direction; the cleaning component includes a cleaning frame disposed between the two sets of guide strips; a rotatable cleaning roller brush is provided on the cleaning frame; rotating rods are provided at both ends of the cleaning roller brush and rotatably pass through the guide openings; an elastic torsion spring is sleeved on the rotating rod, with the inner end connected to the side wall of the rotating rod and the outer end connected to the top of the guide strip; the cleaning frame is a semi-cylindrical structure, slidably connecting the cleaning frames on both sides, with an opening on the flat side for mounting the cleaning roller brush, a wind-facing surface that cooperates with the air nozzle on the upper end of the convex side, and a metal strip that cooperates with the electromagnet on the lower end of the convex side.

[0015] Preferably, a ring of inflatable and deflated sealed airbags is provided along the upper edge of the cover opening of the mounting bracket; the air pump unit is connected to the air nozzle and the air inlet, and is also connected to the sealed airbags.

[0016] Preferably, a lightning sensor is installed on the crossbeam.

[0017] The present invention also proposes an electrical device that uses the energy storage device described in any of the preceding claims for power supply.

[0018] Compared with existing technologies, this invention has the following beneficial technical effects: By movably setting multiple sets of photovoltaic modules on the mounting frame, each photovoltaic module can move and rotate independently according to monitoring data to adjust the position of the corresponding solar panel, maximizing sunlight absorption and improving power generation efficiency at different positions. A cleaning component is incorporated, using a pusher to spray air and a reset component to absorb it. The cleaning component moves up and down in conjunction with the pusher and reset components, while elastic torsion springs extend and retract synchronously, enabling back-and-forth movement and cleaning on the end face of the solar panel. Removing coverings maintains the working performance of the solar panel. The pusher also draws in air from behind the mounting frame, accelerating heat dissipation and maintaining the working performance of the solar panel. In case of extreme weather, adjacent mounting frames rotate until the solar panels are facing each other and close together. Then, two sets of sealing airbags inflate to form a sealed environment to protect the solar panel and reduce damage to the device. Ultimately, through the above structural combination, efficient energy storage and energy conservation are achieved. Attached Figure Description

[0029] Example 1

[0030] like Figure 1-Figure 2 As shown, the present invention proposes an energy storage device, including a mounting frame, which is a frame composed of mounting boxes 1 on the left and right sides and crossbeams 2 on the upper and lower sides; multiple sets of photovoltaic modules are movably mounted on the mounting frame, and the spacing and working angle are adjustable; solar energy control equipment and power storage and conversion equipment are installed on the mounting boxes 1 to assist the operation of each photovoltaic module.

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

[0032] The photovoltaic module includes a mounting frame 3 that can move horizontally and rotate along the crossbeam 2; a second mounting frame 5 is flipped and positioned on the front side of the mounting frame 3; the solar panel 4 and the cleaning component 6 are both mounted on the front end of the second mounting frame 5.

[0033] The cleaning component 6 includes a pusher 601 located above the solar panel 4, a resetter 602 located below the solar panel 4, and a cleaning component 603 located between the pusher 601 and the resetter 602. The cleaning component 603 moves back and forth under the jet of the pusher 601 and the suction of the resetter 602 to clean the end face of the solar panel 4.

[0034] like Figure 1-Figure 5 As shown, multiple light sensors 7 and tracks are arranged along the length of the crossbeam 2; the track is equipped with a drive unit for horizontal movement and rotation of the drive mounting frame 3.

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

[0036] It should be further explained that the driving components include a lead screw 9 driven by a motor and rotating on the track; a moving block 8 is connected to the lead screw 9 by a thread to move horizontally along the track; a rotating shaft 11 is driven by a motor, with one end rotating on the moving block 8 and the other end connected to the mounting bracket 3; the movement and rotation of the mounting bracket 3 can drive the solar panel 4 to move synchronously, adjusting its position and angle to match the detection results of the light sensor 7.

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

[0038] The solar panel 4 is rotated on mounting bracket 3 by mounting bracket 2 5, causing it to flip outwards and adjusting its angle. The angle between the solar panel and the sunlight, i.e., the tilt angle of the solar panel, directly affects its power generation efficiency. To maximize sunlight absorption and improve power generation efficiency, multiple factors such as geographical location, season, weather, and installation environment need to be considered to determine the optimal tilt angle. In this invention, the solar panel 4 is moved and rotated to adapt to changes in the solar altitude angle under different seasons and weather conditions, thereby obtaining the maximum solar irradiation effect.

[0039] like Figure 6 As shown, mounting bracket 2 5 is provided with a ventilation opening 501 and a mounting groove 502; a support rod 13 is provided between mounting bracket 2 5 and mounting bracket 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; the fixing block is located on mounting bracket 1 3.

[0040] When the mounting bracket 25 is flipped, the support rod 13 slides and rotates synchronously, providing support for the mounting bracket 25 to maintain the stability of the solar 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 disposed through the top of the mounting bracket 2 5, and contains a mutually cooperating air pump group and pressurization equipment; the jet nozzle 60102 is disposed at the front end of the air pump box 60101, and sprays air downwards through the air outlet end of the air pump group; the air inlet 60103 is disposed at the rear end of the air pump box 60101, and intakes air downwards through the air inlet end of the air pump group.

[0042] Because the solar panel 4 is working, the ventilation behind the mounting bracket 2 5 is poor, and heat is not easily dissipated. By using an air pump group and pressurization equipment, on the one hand, the air inlet 60103 draws in air from behind the mounting bracket 2 5, which can accelerate heat dissipation; on the other hand, the jet nozzle 60102 provides propulsion by jetting downwards, which drives the cleaning component 603 to move.

[0043] The reset component 602 is a horizontally arranged strip electromagnet; the electromagnet can generate an attractive force when energized, attracting the cleaning component 603.

[0044] Hollow guide bars 604 are provided on both sides of the slot on the mounting bracket 2 5; two sets of guide bars 604 are arranged parallel to each other on both sides of the solar panel 4, and guide openings 60401 are provided on the opposite ends along the length direction; the cleaning component 603 includes a cleaning frame 60301 disposed between the two sets of guide bars 604; a rotatable cleaning roller brush 60303 is provided on the cleaning frame 60301; a rotating rod is provided at both ends of the cleaning roller brush 60303, which rotates through the guide openings 60401; an elastic torsion spring 60304 is sleeved on the rotating rod, with the inner end connected to the side wall of the rotating rod and the outer end connected to the top of the guide bar 604.

[0045] It should be further explained that the cleaning rack 60301 has a semi-column structure, with the two sides of the cleaning rack 60301 slidably connected. The flat side has an opening for the cleaning roller brush 60303 to be installed, the upper end of the convex side is provided with a wind-facing 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 nozzle 60102 sprays air downwards onto the windward side of the cleaning frame 60301, it not only generates a downward thrust but also provides a cleaning effect through airflow. The cleaning roller brush 60303 moves downwards and rolls to clean the solar panel 4. During the descent of the cleaning frame 60301, the elastic torsion spring 60304 is stretched. The electromagnet is energized, attracting the metal strip 60302, which assists the descent of the cleaning frame 60301. When the cleaning frame 60301 stops at the electromagnet, the elastic torsion spring 60304 is stretched to its limit; this stillness has a power-saving effect. When the electromagnet is de-energized, the nozzle 60102 stops spraying air, and the elastic torsion spring 60304 rebounds, causing the cleaning frame 60301 to move upwards and return to its original position. The repeated interaction between the nozzle 60102 and the electromagnet achieves the up-and-down reciprocating cleaning motion of the cleaning roller brush 60303.

[0047] like Figures 8-9 As shown, a ring of inflatable and deflated sealed airbags 12 is provided along the opening of the cover on the mounting bracket 3; the air pump unit is connected to the air nozzle 60102 and the air inlet 60103, and is also connected to the sealed airbags 12.

[0048] When lightning strikes, the two adjacent mounting brackets 3 rotate until the solar panels 4 are facing each other and close together. Then, the two sets of sealing airbags 12 are inflated to 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 installed on beam 2 to assist the device in judging severe weather.

[0050] Example 2

[0051] This embodiment, based on the energy storage device in Embodiment 1, proposes a working method for the energy storage device. Taking two sets 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. Based on the monitoring data, the mounting brackets 3 on the two sets of photovoltaic modules move and rotate respectively, driving the two sets of solar panels 4 to move, and adjusting the position and angle of the two sets of solar panels 4 in a targeted manner; the mounting bracket 5 rotates on the mounting bracket 3, causing the solar panels 4 to flip outward, further adjusting the angle of the solar panels 4 so that their position matches the angle and position of the light; the two sets of solar panels 4 can be on the same side or on both sides, and the trajectory of rotation and movement can be the same or different;

[0054] S3. When thunderstorms are detected, the two adjacent sets of mounting brackets 3 are rotated until the solar panels 4 are facing each other and close to each other. Then, the two sets of sealing airbags 12 are inflated until they fit together, forming a sealed environment to protect the solar panels 4.

[0055] S4. Periodically start the air pump group and pressurization equipment. The air inlet 60103 draws in the air behind the mounting bracket 25, which can accelerate heat dissipation. The jet nozzle 60102 provides propulsion by jetting downwards, which drives the cleaning part 603 to move.

[0056] S5. When the jet nozzle 60102 sprays gas downwards to the windward side of the cleaning rack 60301, the cleaning roller brush 60303 moves down and rolls to clean the solar panel 4.

[0057] S6. As the cleaning rack 60301 descends, the elastic torsion spring 60304 is stretched; the electromagnet attracts the metal strip 60302, which assists in the descent of the cleaning rack 60301.

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

[0059] S8. When the electromagnet is de-energized, the jet nozzle 60102 stops jetting, the elastic torsion spring 60304 rebounds, and the cleaning rack 60301 moves upward to reset.

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