Description

Technical Field

[0001] The present invention relates to the field of photovoltaic charging technology, and in particular to a household photovoltaic storage and charging integrated power station. Background Art

[0002] A household photovoltaic charging station is a modern energy system that combines photovoltaic power generation, energy storage systems and charging facilities. This power station is designed for use in homes or small commercial locations to provide sustainable, efficient and reliable energy solutions.

[0003] Since the power generation efficiency of solar energy storage panels is affected by light intensity and light angle, and household solar energy storage charging stations differ greatly from large charging stations in scale and intelligence, solar energy storage panels are mostly used at fixed angles, while the sun's altitude angle and azimuth angle are always changing, and fixed-angle solar energy storage panels have lower power generation efficiency.

[0004] For example, a Chinese patent with publication number CN216033877U discloses a photovoltaic energy storage charging pile with self-adjusting photovoltaic panel angle. The photovoltaic energy storage charging pile with self-adjusting photovoltaic panel angle can sense light by using a photosensitive sensor installed on the upper part of the photovoltaic panel body, and can control the servo motor to drive the rotating rod to rotate by using a single-chip microcomputer to receive and transmit signals, thereby adjusting the angle of the photovoltaic panel body and collecting light energy over a large area.

[0005] The above patent uses a photosensitive sensor for sensing and a servo motor for angle adjustment. However, when in use, if the area of ​​the photovoltaic panel on the top is too small, the power generation power will be too low. If the area of ​​the photovoltaic panel on the top is too large and there is a lack of a locking mechanism, the angle will be unstable under the influence of external factors such as wind force and will affect the service life of the servo motor.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to solve the technical problem that the solar energy storage panels with fixed angles have low power generation efficiency because the solar altitude and azimuth angles are always changing, such as Figure 1-Figure 10 As shown, the following preferred technical solutions are provided:

[0033] A household photovoltaic storage and charging integrated power station comprises a fixed plate 1 and a solar panel assembly 2 movably arranged on the fixed plate 1, and also comprises an adjustment mechanism 3 arranged between the fixed plate 1 and the solar panel assembly 2, wherein the solar panel assembly 2 comprises a main frame 21 and an outer frame 22 obliquely distributed around the main frame 21, wherein a main solar panel 211 is mounted on the surface of the main frame 21, and an outer solar panel 221 is mounted on the surface of the outer frame 22, the main solar panel 211 is used to collect electric energy, and the relatively distributed outer solar panels 221 are used to compare power to determine whether the angle of the solar panel assembly 2 is facing directly toward the sun, and the solar panel assembly 2 also comprises a current and voltage sensor 23 fixedly mounted on the inner side of the outer frame 22, and the current and voltage sensor 23 is provided with four groups for detecting the electric energy power generated by the outer solar panel 221 respectively;

[0034] The adjusting mechanism 3 includes a motor 31 fixedly mounted on the top of the fixed plate 1, and a rotating disk 32 rotatably arranged inside the fixed plate 1, the output end of the motor 31 is fixedly connected to the rotating disk 32, the outer edge of the rotating disk 32 is installed with a guide plate 321, and the guide plate 321 is inclined, the adjusting mechanism 3 also includes an adjusting rod 33 slidably arranged on the fixed plate 1, the top of the adjusting rod 33 is movably installed with the solar panel assembly 2, wherein the adjusting rod 33 is provided with four groups, a push-pull electromagnet 35 is fixedly mounted inside the fixed plate 1, the push-pull electromagnet 35 is provided with four groups, and the output ends of the push-pull electromagnet 35 are fixedly connected with a locking block 36, the locking block 36 is used to lock the adjusting rod 33, the inner side of the adjusting rod 33 is evenly distributed with guide rods 37, the guide rods 37 correspond to the guide plate 321 on the outer edge of the rotating disk 32, and the spacing between two adjacent groups of guide rods 37 corresponds to the thickness of the rotating disk 32;

[0035] A circuit board 5 is installed at the bottom of the fixed plate 1. The outer solar panel 221, the current and voltage sensor 23, the push-pull electromagnet 35 and the circuit board 5 are electrically connected. A power calculation module, a threshold setting module and a threshold judgment module are arranged in the circuit board 5. The circuit board 5 is used to calculate the difference between the solar panel assembly 2 and the direct sunlight angle according to the power of the outer solar panel 221, and drive the motor 31 and the push-pull electromagnet 35, and then adjust the angle of the solar panel assembly 2 through the adjustment rod 33; because the outer frame 22 is tilted and distributed around the main frame 21, when the two groups are relatively arranged When the external solar panels 221 are exposed to sunlight, if one group of the external solar panels 221 is exposed to sunlight at a better angle, while the other group of the external solar panels 221 is exposed to sunlight at a worse angle, it means that the main solar panel 211 is not directly exposed to sunlight, and the angle needs to be adjusted. At this time, the power generated by the external solar panels 221 exposed to better sunlight is greater than the power of the other group of external solar panels 221. This is used as a judgment to control the motor 31 and the push-pull electromagnet 35, and finally the purpose of controlling the adjustment rod 33 to adjust the angle of the main solar panel 211 is achieved.

[0036] A fixed shaft 11 is fixedly installed on the top of the fixed plate 1, and a rotating ball 12 is fixedly installed on the top of the fixed shaft 11. A ball seat 13 corresponding to the rotating ball 12 is fixedly connected to the middle of the bottom of the main frame 21, wherein the rotating ball 12 is movably arranged at the bottom of the ball seat 13. The fixed shaft 11, the rotating ball 12 and the ball seat 13 form a movable mechanism placed under the fixed plate 1 and the rotating ball 12, so that the fixed plate 1 and the solar panel assembly 2 form a movable connection.

[0037] A slide groove 14 corresponding to the adjustment rod 33 is provided on the fixed plate 1, and a corrugated hose 15 is installed between the top of the fixed plate 1 and the solar panel assembly 2. The corrugated hose 15 is used to prevent dust from entering the area between the fixed plate 1 and the solar panel assembly 2, thereby reducing the failure rate of the structure in this area.

[0038] The current and voltage sensor 23 is used to record the current and voltage of the external solar panels 221 in real time. The power calculation module can calculate the power of each group of external solar panels 221 according to the formula "W=U*I". The threshold setting module is used to set the power difference allowed between two groups of external solar panels 221. The threshold judgment module is used to judge whether the power difference generated between the external solar panels 221 that are relatively set is greater than the set threshold. For example, the threshold is set to 6W. When the power generated by the first group of external solar panels 221 is 12W, and the power generated by the third group of external solar panels 221, i.e., the external solar panels 221 that are relatively set to the first group, is 21W, 21W-12W>6W, which means that angle adjustment is required.

[0039] A battery 4 and an inverter 6 are also provided below the fixed plate 1. The battery 4, the circuit board 5 and the inverter 6 are electrically connected. The battery 4 is used to store the electric energy generated by the main solar panel 211 and the external solar panel 221. The inverter 6 is used to convert the electric energy stored in the battery 4 into alternating current for use.

[0040] A movable rod 331 is provided at the top of the adjusting rod 33, and a fixed frame 34 is provided at the bottom of the main frame 21, and the fixed frame 34 is provided with four groups. A guide groove 341 is provided on the fixed frame 34, and the movable rod 331 is movably provided in the guide groove 341. When one group of adjusting rods 33 descends, the other group of adjusting rods 33 opposite to the adjusting rod 33 will move upward in a state of active connection.

[0041] The adjusting rod 33 is also provided with a locking groove 332, which corresponds to the locking block 36. The locking block 36 is a component made of iron. The cross-section of the locking block 36 and the locking groove 332 is a right-angled trapezoid with the tip facing downward. When the locking block 36 and the locking groove 332 cooperate, the adjusting rod 33 can be prevented from being lowered by external force, forming a self-locking structure. The push-pull electromagnet 35 is in an extended state when the power is off. When the locking block 36 of one group does not lock the adjusting rod 33 and the adjusting rod 33 is descending, the adjusting rod 33 of the other group is in a raised state. The trapezoidal structure formed between the locking block 36 and the adjusting rod 33 will cause the inclined surface of the locking groove 332 to squeeze the inclined surface of the locking block 36, and finally cause the push-pull electromagnet 35 and the locking block 36 to retract, thereby not affecting the raising of the adjusting rod 33 by external force.

[0042] The adjusting rod 33 is also provided with a sliding groove 333, a mounting groove 334 and a movable groove 335, wherein the movable groove 335 is connected to the outside from the inner side of the adjusting rod 33, the guide rod 37 is slidably connected in the movable groove 335, and one end of the guide rod 37 located inside the adjusting rod 33 is fixedly connected with a permanent magnet 371, and a reset spring 372 is fixedly connected between the inner side of the permanent magnet 371 and the inner wall of the mounting groove 334. When the push-pull electromagnet 35 is in the power-off extended state, the locking block 36 is located in the locking groove 332, and a magnetic field is generated between the locking block 36 and the permanent magnet 371. In this state, the other end of the guide rod 37 is located in the adjusting rod 33. At this time, when the motor 31 drives the rotating disk 32 to rotate clockwise, the guide plate 321 does not contact the guide rod 37, and the adjusting rod 33 does not move; when the push-pull electromagnet 35 is energized and retracted, the locking block 36 retracts, and the guide rod 37 is reset by the reset spring 372. The other end of the guide rod 37 extends from the movable groove 335 to the outside of the adjusting rod 33. When the motor 31 drives the rotating disk 32 to rotate clockwise, the guide plate 321 rotates and presses down the guide rod 37, so that the adjusting rod 33 can be lowered.

[0043] A mounting mechanism 7 is installed below the fixed plate 1, and the mounting mechanism 7 is used to install the entire device. The mounting mechanism 7 includes a shell 71 fixedly connected to the bottom of the fixed plate 1, and the shell 71 is used to protect the battery 4, circuit board 5 and inverter 6 below the fixed plate 1. A rotating seat 72 is fixedly installed at the bottom of the shell 71, and a rotating plate 73 is rotatably connected to the bottom of the rotating seat 72, and a fixed seat 74 is rotatably connected to the bottom of the rotating plate 73. The rotating seat 72 is rotatably connected to the rotating plate 73, and the rotating plate 73 is rotatably connected to the fixed seat 74, so that the angle can be pre-adjusted during installation.

[0044] Specifically, when the angle of sunlight changes, since the four groups of outer solar panels 221 are installed at an angle, the power difference between the relatively arranged outer solar panels 221 gradually increases. When the power difference is greater than the set threshold, the outer solar panel 221 receiving better irradiation should be adjusted downward by the adjusting rod 33. At this time, the corresponding push-pull electromagnet 35 is energized and retracted, and the guide rod 37 at this location is reset by the reset spring 372, and the other end of the guide rod 37 extends from the inner side of the adjusting rod 33, while the guide rods 37 of the other three groups on the same horizontal plane are still in the adjustment position. Inside the rod 33, when the motor 31 drives the rotating disk 32 to rotate clockwise, the guide plate 321 squeezes the guide rod 37 to make the adjusting rod 33 move downward, and another group of adjusting rods 33 that are relatively distributed move upward under the principle of lever. After the adjusting rod 33 moves upward, the push-pull electromagnet 35 at this location will make the locking block 36 insert into the locking groove 332, and the guide rod 37 at this location is still inside the adjusting rod 33. The push-pull electromagnet 35 and the locking block 36 can not only play a locking role, but also control whether the guide rod 37 is in contact with the guide plate 321. The operation is simple and the structure is stable.
