[0026] 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.

[0027] like Figure 1-7 As shown, the present invention provides a distributed photovoltaic energy efficiency improvement power optimization device, including a shell 1, the shell 1 is divided into an upper shell 11 and a lower shell 12, the upper shell 11 and the lower shell 12 are symmetrically arranged, an optimization body 13 is arranged between the upper shell 11 and the lower shell 12, vertically arranged baffles 14 are fixedly arranged at both ends of the inner wall side of the upper shell 11 and the lower shell 12, a plurality of through holes 15 are opened on the baffle 14 and are evenly spaced, an end of the outer wall of the lower surface away from the upper shell 11 is fixedly installed with a mounting cover 2, both end hoops of the mounting cover 2 are provided with partitions 21, an air outlet assembly is arranged in the middle of the two partitions 21 in the mounting cover 2, and a temperature sensor 16 is installed at one end of the upper shell 11 and the lower shell 12.

[0028] The air outlet assembly includes a piston tube 3, and the piston tube 3 is provided with a plurality of piston tubes 3 provided with equal spacing and inserted on the partition 21. A movable plate 22 is fixedly provided at the middle end inside the mounting cover 2, and connecting plates 27 are fixedly provided at both ends of the movable plate 22. A piston rod 33 is fixedly provided at one end of the connecting plate 27 away from the movable plate 22, and one end of the piston rod 33 away from the connecting plate 27 is inserted in the corresponding piston tube 3. The piston rod 33 is provided with a piston head 34 in the piston tube 3, and an air inlet pipe 31 is connected to the lower part of the piston tube 3, and a one-way valve is installed on the air inlet pipe 31. The one-way valve can only ensure that the gas enters the piston tube 3 from the intake pipe 31. At the same time, when the piston head 34 squeezes and pushes the gas, the gas will not be discharged from the intake pipe 31. A rectangular groove 23 is opened through the middle end of the movable plate 22, and an arc groove 24 is opened at the diagonal of the rectangular groove 23. A vertically arranged rotating rod 25 is provided at the middle end of the rectangular groove 23. A Y-shaped pushing block 26 is fixed on the top of the rotating rod 25. The end of the pushing plate 4 can be against the side wall of the rectangular groove 23, and the output pipe 32 is passed between the two sides of the outer wall of the mounting cover 2 and the lower shell 12.

[0029] A heat sink 35 is fixedly installed in the installation cover 2 between the partition 21 and the inner wall thereof. The heat sink 35 is arranged in a plurality and distributed in a rectangular shape. When the piston tube 3 is driven so that gas is input near the heat sink 35, the heat sink 35 will cool the contacted gas. At the same time, the heat sink 35 is distributed at intervals, which can increase the contact with the gas while preventing the movement of the gas from being blocked, thereby ensuring that the subsequent gas can be smoothly transported to the shell 1 through the output pipe 32.

[0030] A drive motor 28 is fixedly provided on the outer wall of the mounting cover 2 near the rotating rod 25. The output end of the drive motor 28 is coaxially fixedly provided on the rotating rod 25. The drive motor 28 is electrically connected to the temperature sensor 16. The drive motor 28 can directly and conveniently drive the rotating rod 25 to rotate. When the temperature sensor 16 receives the result that the temperature inside the shell 1 is high, the rotating rod 25 can be directly controlled to work to cool down and dissipate heat inside. A power block 29 is installed on the outer wall of the mounting cover 2 near the drive motor 28. The power block 29 can power the drive motor 28. A mounting sleeve is fixedly provided at the bottom of the intake pipe 31. 36, a dust filter is fixedly provided at the air inlet at the bottom of the installation sleeve 36. The dust filter arranged in the installation sleeve 36 can prevent dust and impurities from entering the gas through the air inlet pipe 31 into the shell 1, which may cause internal impurities to accumulate and cause subsequent power optimization device failure; the interior of the lower shell 12 is located on the inner side of the baffle plate 14 and is fixedly provided with a vertically arranged push plate 4, and the top of the push plate 4 extends to the interior of the upper shell 11. The set push plate 4 can push the gas to move toward the inside of the shell 1 when it is driven to move later, so that the cold air entering the shell 1 is concentrated into the shell 1 to achieve the purpose of rapid cooling.

[0031] A U-shaped synchronization rod 42 is fixedly disposed on the lower surface of the middle end of the connecting plate 27, and an insertion rod 41 is fixedly disposed at one end of the synchronization rod 42 away from the connecting plate 27. The insertion rod 41 penetrates the lower shell 12 and is fixedly connected to the push plate 4. The movement of the connecting plate 27 and the adjacent push plate 4 are synchronized by the synchronization rod 42 and the insertion rod 41, thereby improving the linkage and integrity of the operation of the device and making it faster after operation; a card plate 43 is fixedly disposed at one end of the synchronization rod 42 close to the connecting plate 27, and the card plate 43 can be movably inserted into the interior of the mounting cover 2. The card plate 43 is inserted into the mounting cover 2, thereby preventing external impurities from directly entering the mounting cover 2 and affecting the internal structure when the synchronization rod 42 moves.

[0032] The upper shell 11 is provided with rectangularly distributed heat dissipation holes 111, and the heat dissipation holes 111 are opened in the middle position of the upper shell 11. The heat dissipation holes 111 are mainly used to discharge the internal hot air. At the same time, the heat dissipation holes 111 are set in the middle position to ensure that after the hot air generated from the installation cover 2 is discharged into the shell 1, the gas can be discharged from one end to the middle end, so that the cooling sweep can be guaranteed to optimize the main body 13, thereby ensuring that it can be cooled, avoiding excessive temperature that affects normal operation, and improving the comprehensiveness of heat dissipation.

[0033] A distributed photovoltaic energy efficiency improvement power optimization system includes a photovoltaic component, an optimization component and a photovoltaic inverter component. The photovoltaic component is specifically a photovoltaic panel, and the optimization component is specifically a photovoltaic power optimizer. The optimization component is connected in series with the photovoltaic component to ensure stable transmission of current and voltage. The photovoltaic power optimizer adopts a unique software algorithm and can track the maximum power point of a single component in real time. Users can choose different types of power optimizers according to the actual operating conditions of the photovoltaic system to solve the problem of reduced power generation of the photovoltaic system caused by shadow obstruction, component orientation differences or inconsistent component attenuation, achieve maximum power output and online monitoring of a single component, and improve system efficiency. The photovoltaic inverter component is electrically connected to the optimization component.

[0034] Working principle: When in use, when the temperature inside the housing 1 detected by the temperature sensor 16 is high, the driving motor 28 directly controls the rotating rod 25 to rotate. At this time, the rotating rotating rod 25 will directly drive the pushing block 26 fixed on the top to rotate. First, one end of the pushing block 26 will abut against the side wall of the rectangular groove 23. At this time, the movable plate 22 will be pushed by the end of the pushing block 26 and will move toward one end. At this time, the connecting plate 27 fixed at the end of the movable plate 22 will push the air in the piston tube 3 to move through the piston rod 33 and the piston head 34 on the top. As the end of the pushing block 26 moves into the arc groove 24, the other end of the pushing block 26 will The other side of the rectangular groove 23 is contacted to push the movable plate 22 to move in the opposite direction to the previous direction. As the driving motor 28 drives the pushing block 26 to rotate continuously, the movable plate 22 can be moved back and forth repeatedly. At this time, the connecting plates 27 fixed at both ends of the movable plate 22 will continuously drive the piston rod 33 to work back and forth, so that the gas can directly move out through the end of the piston tube 3 to the position of the heat dissipation strip 35. The heat dissipation strip 35 will cool the contacted gas. At the same time, the heat dissipation strips 35 are spaced apart to increase the contact with the gas while preventing the movement of the gas from being blocked, so as to ensure that the subsequent gas can be smoothly transported to the shell 1 through the output pipe 32;

[0035] At this time, the gas cooled by the heat dissipation strip 35 will be input into the shell 1 through the output pipe 32. At this time, when the connecting plate 27 is repeatedly moved back and forth by the above-mentioned movable plate 22, the synchronous rod 42 fixedly arranged under the connecting plate 27 will drive the plug-in driving push plate 4 to move repeatedly. At this time, the push plate 4 can push the gas to move toward the inside of the shell 1 when being driven to move, so that the cold air entering the shell 1 is concentrated into the shell 1 to achieve the purpose of rapid cooling. As the cooled cold air moves to the middle position of the shell 1, the internal hot air will be mainly discharged through the heat dissipation holes 111. At the same time, the position of the heat dissipation holes 111 is set in the middle position, which can ensure that after the hot air generated in the installation cover 2 is discharged into the shell 1, the gas can be discharged from one end to the middle end, so that the cooling can sweep the optimization body 13, thereby ensuring that it is cooled, avoiding excessive temperature affecting normal operation, and improving the comprehensiveness of heat dissipation.
