Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic power generation charging pile. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels, controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. Charging piles function similarly to gas pumps in gas stations. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels and can also be equipped with lighting, media broadcasting, and other functions.

[0003] Most existing charging stations use solar photovoltaic panels for charging. They require strong light sources to charge the internal batteries, so the angle at which the photovoltaic panels receive the light needs to be adjusted. In open-air locations, dust accumulates on the surface of the photovoltaic modules, reducing the amount of solar radiation reaching the battery surface and altering the heat transfer pattern. At the same time, the dust absorbs solar radiation and converts it into its own heat, blocking the heat dissipation of the photovoltaic module's cover glass. Therefore, it is necessary to clean the surface of the photovoltaic panels regularly.

[0004] However, the angle adjustment of existing photovoltaic charging piles on the market is inconvenient, requires manual operation, has low adjustment efficiency, and the auxiliary cleaning structure is prone to jamming after dust accumulation, making it unable to effectively clean the photovoltaic panels.

[0036] 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.

[0037] See Figure 1 A photovoltaic power generation charging pile includes a charging pile body 1, a photovoltaic panel 2 disposed outside the charging pile body 1, and a control system disposed inside the charging pile body 1, and also includes an angle adjustment mechanism 3 and a cleaning mechanism 4.

[0038] The angle adjustment mechanism 3 is disposed on the top of the charging pile body 1 and electrically connected to the control system, and is used to adjust the angle of the photovoltaic panel 2 disposed above the angle adjustment mechanism 3;

[0039] The cleaning mechanism 4 is disposed on the surface of the photovoltaic panel 2 and is connected in cooperation with the angle adjustment mechanism 3 for cleaning the photovoltaic panel 2.

[0040] Preferred, see Figure 2 and Figure 4 , Figure 2 for Figure 1 A partially enlarged schematic diagram at point A shows that the angle adjustment mechanism 3 includes an active structure, a driven structure, and a connecting structure that are mechanically connected in sequence.

[0041] The active structure includes an active rod 305, a first worm gear 306, a first conical friction wheel 312, and a motor 313. The first worm gear 306 is disposed on the active rod 305, the first conical friction wheel 312 is disposed at both ends of the active rod 305, and the motor 313 is used to drive the first worm gear 306 to rotate.

[0042] The driven structure includes a driven rod 301, a second worm 302, and a rack 304. The second worm 302 is disposed on the driven rod 301. The first worm 306 is used to drive the second worm 302 to rotate in the forward and reverse directions. The rack 304 moves horizontally by the drive of the second worm 302.

[0043] The connection structure includes a mounting frame 311, a connecting shaft 307, a connecting rod 309, and a gear 308. The mounting frame 311 is vertically fixed to the top of the charging pile body 1. The connecting shaft 307 is located at the top of the mounting frame 311 and is rotatably connected to the mounting frame 311. One end of the connecting rod 309 is connected to the connecting shaft 307, and the other end of the connecting rod 309 is connected to the bottom middle of the photovoltaic panel 2. The gear 308 meshes with the rack 304 and is fixedly connected to the connecting shaft 307.

[0044] In one embodiment of the above scheme, the photovoltaic panel 2 is located on top of the charging pile body 1 to generate photovoltaic power. The power generated by the photovoltaic panel 2 enters the storage battery and is supplied to the charging pile body 1 and the angle adjustment mechanism 3 respectively. The control system is set inside the charging pile body 1 to control the power distribution of the entire charging pile and the angle adjustment of the photovoltaic panel 2.

[0045] Specifically, the angle adjustment mechanism 3 includes an active structure, a driven structure, and a connecting structure mechanically connected in sequence. The active structure includes an active rod 305, a first worm gear 306, a first conical friction wheel 312, and a motor 313. The driven structure includes a 301, a second worm gear 302, and a rack 304. The first worm gear 306 and the second worm gear 302 cooperate with each other. The rotation of the first worm gear 306 drives the second worm gear 302 to move horizontally along the support plate 310, which in turn drives the rack 304 to move. The rack 304 meshes with the gear 308 of the connecting structure, thereby driving the gear 308. The gear 308 drives the connecting shaft 307 to rotate. The connecting shaft 307 is rotatably connected to the mounting bracket 311 and is connected to the photovoltaic panel 2 through the connecting rod 309. Therefore, when the connecting shaft 307 rotates, it will drive the photovoltaic panel 2 to rotate, thereby completing the angle adjustment.

[0046] It is understandable that the rotation of the drive rod 305 is achieved through the cooperation of the motor 313 and the gear assembly 407. When the motor 313 rotates, it distributes power to the drive rod 305 and the first worm gear 306 via the gear assembly 407. The rotation of the first worm gear 306 drives the second worm gear 302 to move, which in turn drives the gear 308 to rotate. Therefore, by controlling the speed of the motor 313 through the control system, the angle of the photovoltaic panel 2 can be precisely adjusted.

[0047] Preferred, see Figure 2 The angle adjustment mechanism 3 also includes a support plate 310 and a first spring 303;

[0048] The two support plates 310 are vertically arranged on the top of the charging pile body 1 and are rotatably connected to the active rod 305 and keyed to both ends of the second worm gear 302;

[0049] The first spring 303 is located at both ends of the second worm 302 and is fixedly connected to the support plate 310.

[0050] In one embodiment of the above scheme, first springs 303 are sleeved at both ends of the second worm 302. When the second worm 302 is driven to move by the first worm 306, it will compress one side of the spring until the second worm 302 disengages from the first worm 306. At this time, the driven rod 301 no longer moves, the rack 304 and the gear 308 are locked, and the photovoltaic panel 2 is adjusted to the maximum tilt angle. At the same time, the first worm 306 continues to rotate to complete the subsequent cleaning of the photovoltaic panel 2 without affecting the angle of the photovoltaic panel 2. When the first worm 306 rotates in the opposite direction, the second worm 302 is reset under the action of the first spring 303, maintaining its engagement with the first worm 306. This facilitates the second worm 302 to move in the opposite direction after the first worm 306 rotates in the opposite direction, thereby completing the angle reset and adjustment of the photovoltaic panel 2.

[0051] Preferred, see Figure 3 , Figure 4 and Figure 5 The cleaning mechanism 4 includes two lead screws 401, a rotating shaft 403, a gear assembly 407, at least two sliders 402, a sweeping rod 406, and a second conical friction wheel 405;

[0052] The two lead screws 401 are respectively located above the two sides of the photovoltaic panel 2. The lead screws 401 are connected to the rotating shaft 403 through the gear assembly 407. Each lead screw 401 is provided with a slider 402, and the two sliders 402 are positioned correspondingly.

[0053] The cleaning rod 406 is located between the two sliders 402, and a brush is provided at the bottom of the cleaning rod 406 for cleaning the photovoltaic panel 2.

[0054] The second conical friction wheel 405 is fixedly disposed in the middle of the rotating shaft 403 and is used to cooperate with the first conical friction wheel 312.

[0055] In one embodiment of the above scheme, when the drive rod 305 and the first worm gear 306 continue to rotate, the photovoltaic panel 2 is adjusted to the maximum tilt angle in one direction along with the gear 308 and the rack 304. At this time, the second conical friction wheel 405 below the photovoltaic panel 2 will abut against the first conical friction wheel 312 on the drive rod 305. Since the continuous rotation of the drive rod 305 will drive the integrated first conical friction wheel 312 to rotate continuously, the second conical friction wheel 405 will rotate accordingly after the first conical friction wheel 312 abuts against the second conical friction wheel 405.

[0056] Furthermore, the rotation of the second conical friction wheel 405 will drive the rotating shaft 403 to rotate, which in turn drives the lead screw 401 to rotate through the gear assembly 407, thereby driving the slider 402 that cooperates with the lead screw to move. The slider 402 drives the cleaning rod 406 to clean the surface of the photovoltaic panel 2. Since the cleaning process occurs when the tilt angle of the photovoltaic panel 2 is at its maximum, the dust after cleaning can slide smoothly down the slope and will not accumulate on the photovoltaic panel 2.

[0057] It is understandable that when the photovoltaic panel 2 adjusts its angle according to the sunlight, it will reach its maximum angle twice a day. Therefore, the photovoltaic panel 2 can be cleaned twice a day, which increases the cleaning frequency. At the same time, the cleaning mechanism 4 and the angle adjustment mechanism 3 share a motor 313, which reduces energy consumption.

[0058] Preferred, see Figure 4 The cleaning mechanism 4 also includes a support frame 404;

[0059] The lead screw 401 is connected to the photovoltaic panel 2 via the support frame 404, and the rotating shaft 403 is located below the lead screw 401 and is rotatably connected to the support frame 404.

[0060] Preferably, the lead of the second worm 302 is less than the lead of the first worm 306.

[0061] Preferred, see Figure 6 The angle adjustment mechanism 3 also includes a second spring 314;

[0062] One end of the second spring 314 is connected to the first conical friction wheel 312, and the other end of the second spring 314 is connected to the active rod 305.

[0063] In one embodiment of the above scheme, the angle adjustment mechanism 3 further includes a second spring 314. The first conical friction wheel 312 is connected to the drive rod 305 via a spline and the second spring 314. When the drive rod 305 and the first worm gear 306 rotate, they synchronously drive the first conical friction wheel 312 to rotate. The first conical friction wheel 312 is also connected to the drive rod 305 via the second spring 314, so that the first conical friction wheel 312 can move and retract axially. During the contact process between the second conical friction wheel 405 and the first conical friction wheel 312, the second spring 314 can provide buffering to ensure that the first conical friction wheel 312 and the second conical friction wheel 405 are tightly abutted, thus avoiding slippage.

[0064] Preferably, the photovoltaic panel 2 is equipped with an MPPT controller, which is electrically connected to the control system.

[0065] In one embodiment of the above scheme, the photovoltaic panel 2 is equipped with an MPPT controller, namely maximum power point tracking. When the sunlight conditions change, the load curve that can provide the maximum power transmission efficiency also changes accordingly. If the load can be adjusted to match the load curve with the highest power transmission efficiency, the system will have the best efficiency. With the help of the light sensor, the angle of the photovoltaic panel 2 can be intelligently adjusted to effectively utilize solar energy and improve power generation efficiency.

[0066] Preferably, the charging pile further includes a storage battery, which is electrically connected to the photovoltaic panel 2, the charging pile body 1, and the motor 313.

[0067] In summary, the photovoltaic power generation charging pile provided by this invention can automatically adjust the angle of the photovoltaic panel and integrate the angle adjustment and surface cleaning of the photovoltaic panel into a single mechanism. Two sets of actions are achieved through a single power source, which improves the angle adjustment and cleaning effects. Part of the electricity generated by the photovoltaic power generation is allocated to the motor for angle adjustment and cleaning, and the other part is supplied to the charging pile for charging, which greatly improves the energy utilization efficiency.

It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of the present invention, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of the present invention.
