Description

Technical Field

[0001] The present invention relates to the technical field of inverters, and particularly to an intelligent multi-functional photovoltaic inverter structure. Background Art

[0002] A photovoltaic inverter is a key device whose function is to efficiently convert the variable DC voltage output by photovoltaic solar panels into alternating current that conforms to the mains frequency, and then to feed back to the commercial power transmission system or supply power to an off-grid power grid. Given that the photovoltaic inverter generates a relatively high internal temperature during operation, it is necessary to be equipped with an effective heat dissipation device and a carefully designed heat dissipation structure to ensure its stable operation. Usually, a combination of a cooling fan and cooling holes is a common heat dissipation solution. However, for a photovoltaic inverter installed outdoors, there is a potential problem with this design: while the cooling holes promote air circulation, they may also become a channel for dust to enter the interior of the inverter. Especially in strong wind weather, the dust content in outdoor air surges, accelerating the accumulation of dust inside the inverter, thereby increasing the risk of equipment failure.

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1: Please refer to Figures 1-4 , the present invention provides a technical solution: an intelligent multi-functional photovoltaic inverter structure, including an inverter main body 1, and further including:

[0042] A plurality of main air inlets 2 are provided on one side of the inverter main body 1, and a plurality of secondary air inlets 3 are provided on the other side of the inverter main body 1;

[0043] An air extraction component 4 is provided inside the inverter main body 1 and is in communication with the main air inlet 2 and the secondary air inlet 3;

[0044] A plurality of air outlets 5 are provided on one side of the inverter main body 1 and surround the secondary air inlet 3, and are used to form an air curtain around the secondary air inlet 3 when air is discharged to prevent dust from entering the secondary air inlet 3;

[0045] An air inlet adjustment component 6 is provided inside the inverter main body 1 and is used to adjust the sizes of the main air inlet 2 and the secondary air inlet 3;

[0046] An air velocity monitoring component 7 is provided on the inverter main body 1 and is connected to the air inlet adjustment component 6, and is used to gradually close the main air inlet 2 and gradually open the secondary air inlet 3 by using the air inlet adjustment component 6 when the air velocity gradually increases;

[0047] Specifically, by designing the secondary air inlet 3 and a plurality of air outlets 5 with smaller diameters distributed around it, when the air outlets 5 supply air, the air velocity is relatively fast and an air curtain can be formed at the secondary air inlet 3, thereby greatly avoiding the inhalation of dust. At the same time, during the process of increasing air velocity, the driving member 56 is used to gradually increase the secondary air inlet 3 while decreasing the main air inlet 2, so that the device can distribute the air intake according to the air velocity. Therefore, when there is no wind in the environment where the device is located, air can enter through the main air inlet 2 for heat dissipation normally to avoid the problem of higher air inlet temperature at the secondary air inlet 3.

[0048] The air extraction component 4 includes a communication pipe 41 conductively connected to one side of the inverter main body 1, and a heat dissipation fan 42 is installed inside the communication pipe 41. Starting the heat dissipation fan 42 sucks external air into the inverter main body 1;

[0049] And a first rectangular box 43 is fixedly connected to one side of the inverter main body 1. Main air inlets 2 are evenly arranged at equal intervals on the first rectangular box 43, and the first rectangular box 43 is conductively connected to the connecting pipe 41. The other side of the inverter main body 1 is conductively connected to a second rectangular box 44. Auxiliary air inlets 3 are evenly arranged at equal intervals on the second rectangular box 44. An air inlet pipe 45 is fixedly connected inside the auxiliary air inlets 3, and one end of the air inlet pipe 45 is conductively connected to a third rectangular box 46. The third rectangular box 46 is located inside the second rectangular box 44. A ventilation pipe 47 is conductively connected between the third rectangular box 46 and the first rectangular box 43. Specifically, the air entering from the auxiliary air inlets 3 will sequentially pass through the air inlet pipe 45, the third rectangular box 46, the ventilation pipe 47 and enter the first rectangular box 43;

[0050] An air outlet 5 is opened on the second rectangular box 44.

[0051] The air outlet 5 is designed with a diameter smaller than that of the auxiliary air inlets 3. This design will make the gas flow rate discharged from the air outlet 5 relatively large, thereby forming an air curtain around the auxiliary air inlets 3. At this time, the dust in the air will be isolated and taken away by it, thus greatly reducing the dust content inhaled by the auxiliary air inlets 3.

[0052] The air inlet adjusting assembly 6 includes a fixed circular plate 48 fixedly connected to the end of the main air inlet 2. A plurality of fan-shaped slots 49 are evenly arranged at equal intervals on the fixed circular plate 48. A first shaft 51 is rotatably connected to the fixed circular plate 48 through a bearing. A rotating circular plate 52 is fixedly connected to the first shaft 51. Fan-shaped slots 49 are also opened on the rotating circular plate 52. Rotate the rotating circular plate 52 to block the main air inlet 2;

[0053] And a swing plate 53 is fixedly connected to one end of the first shaft 51. A second shaft 54 is fixedly connected to one end of the swing plate 53. A first connecting rod 55 is rotatably connected between a plurality of second shafts 54. Move the first connecting rod 55 to drive a plurality of swing plates 53 to deflect, and further drive a plurality of rotating circular plates 52 to rotate;

[0054] A fixed circular plate 48 is also fixedly connected to the end of the air inlet pipe 45. A plurality of fan-shaped slots 49 are also evenly arranged at equal intervals on the fixed circular plate 48. A first shaft 51 is also rotatably connected to the fixed circular plate 48. A rotating circular plate 52 is also fixedly connected to the first shaft 51. Fan-shaped slots 49 are also opened on the rotating circular plate 52. Rotate the rotating circular plate 52 to block the main air inlet 2;

[0055] And a swing plate 53 is also fixedly connected to one end of the first shaft 51. A second shaft 54 is also fixedly connected to one end of the swing plate 53. A first connecting rod 55 is also rotatably connected between a plurality of second shafts 54. Move the first connecting rod 55 to drive a plurality of rotating circular plates 52 to rotate. And a driving member 56 is arranged inside the inverter main body 1 for driving the first connecting rod 55 to move.

[0056] The driving member 56 includes an electric push rod 57 fixedly connected inside the first rectangular box 43. A second connecting rod 83 is rotatably connected between the extending end of the electric push rod 57 and the first connecting rod 55 inside the first rectangular box 43 through a rotating shaft.

[0057] An electric push rod 57 is also fixedly connected inside the third rectangular box 46. A second connecting rod 83 is rotatably connected between the extending end of the electric push rod 57 and the first connecting rod 55 inside the third rectangular box 46 through a rotating shaft.

[0058] The wind speed monitoring component 7 includes a wind speed sensor 58 installed on the inverter main body 1, and the wind speed sensor 58 is electrically connected to the controller of the electric push rod 57.

[0059] Specifically, when there is no wind or the wind is very small in the external environment of the device, the dust particles in the environment are also relatively stable, so that the dust content in the air is relatively low. At this time, the wind speed sensor 58 does not rotate, and the main air inlet 2 of the device is in a fully open state, while the auxiliary air inlet 3 is in a fully sealed state, enabling the device main body to perform normal heat dissipation operations and not inhaling much dust. On the contrary, when the wind is strong, the dust content in the air is also high. At this time, the wind speed sensor 58 rotates, and then the electric push rod 57 is controlled to work through a program to gradually close the main air inlet 2 while gradually opening the auxiliary air inlet 3, so as to effectively avoid dust inhalation by using the air curtain effect of the air outlet 5. The design of distributing the air intake according to the wind speed is to minimize the air entering the device main body from the auxiliary air inlet 3, because the auxiliary air inlet 3 is relatively close to the air outlet 5, and the gas inhaled from the auxiliary air inlet 3 may be heated by the gas flowing out from the air outlet 5, thus affecting the heat dissipation efficiency of the device.

[0060] Embodiment 2: Please refer to Figures 1-10 , the present invention provides a technical solution: Embodiment 2 is another specific implementation manner of the driving member 56 and the wind speed monitoring component 7 in Embodiment 1;

[0061] The wind speed monitoring component 7 includes a U-shaped frame 59 fixedly connected to the inverter main body 1. A third shaft 61 is rotatably connected to the U-shaped frame 59 through a bearing. One end of the third shaft 61 is fixedly connected with a plurality of wind cups 62 at equal intervals and evenly. When the wind blows towards the wind cups 62, it will drive the third shaft 61 to rotate. The greater the wind, the faster the third shaft 61 rotates.

[0062] The driving member 56 includes a guide rod 63 fixedly connected to the first connecting rod 55. A slider 64 is slidably connected to the guide rod 63. One end of the slider 64 is fixedly connected with a push rod 65. The push rod 65 is slidably connected to the first rectangular box 43, the second rectangular box 44, and the third rectangular box 46. A transmission member 66 is provided between the push rod 65 and the third shaft 61. When the rotation speed of the third shaft 61 changes, the transmission member 66 is used to drive the push rod 65 to move.

[0063] The transmission member 66 includes a lever 67 rotatably connected to the inverter body 1 through a rotating shaft. Both ends of the lever 67 are provided with sliding grooves 68. One end of the push rod 65 is fixedly connected with a sliding column 69 with one end located in the sliding groove 68, and the sliding column 69 is slidably connected with the inner wall of the sliding groove 68;

[0064] And a hollow shaft four 71 is rotatably connected to the U-shaped frame 59 through a bearing. One end of the hollow shaft four 71 is fixedly connected with a first gear disk 72. One end of the shaft three 61 is fixedly connected with a second gear disk 73 meshing with the first gear disk 72. Two swing rods 74 are symmetrically rotatably connected to the hollow shaft four 71 through a rotating shaft. One end of each of the two swing rods 74 is fixedly connected with a counterweight 75. And a cylinder 76 is slidably connected in the hollow shaft four 71. Both sides of the cylinder 76 are fixedly connected with mounting plates 77. The hollow shaft four 71 is provided with a guiding groove 78, and one end of the mounting plate 77 slidably passes through the guiding groove 78;

[0065] A third connecting rod 79 is rotatably connected between the mounting plate 77 and the swing rod 74 through a rotating shaft. And a shaft five 81 is rotatably connected to the cylinder 76. One end of the shaft five 81 passes through the hollow shaft four 71 and is fixedly connected with a rectangular plate 82. One end of the rectangular plate 82 is also fixedly connected with a sliding column 69. One end of the sliding column 69 is located in the sliding groove 68 and is slidably connected with its inner wall;

[0066] Specifically, when the wind speed is relatively high, it will blow the wind cup 62 to rotate rapidly, thereby driving the shaft three 61 and the second gear disk 73 to rotate, thus driving the first gear disk 72, the hollow shaft four 71, and the swing rod 74 to rotate. Then, the centrifugal force received by the counterweight 75 is used to drive the third connecting rod 79 to move, thereby driving the sliding column 69, the shaft five 81, and the rectangular plate 82 to move, thus driving the lever 67 to deflect, and further driving the push rod 65 and the first connecting rod 55 to move, and then driving the swing plate 53 to deflect, thereby driving the rotating circular plate 52 to rotate, so as to block the main air inlet 2 and open the secondary air inlet 3 at the same time.

[0067] The first gear disk 72 is designed with a diameter smaller than that of the second gear disk 73. Thus, when the shaft three 61 rotates, it can drive the shaft four to rotate at a speed greater than that of the shaft three 61, thereby improving the reaction speed of the device.
