[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides an outdoor power-saving inverter, which reasonably utilizes the internal space of the box by adjusting the position of the inverter body, avoiding the waste of space caused by the rear side space of the inverter body being too large. At the same time, by adjusting the position of the inverter body to be close to the front side of the box, the wiring operation can be performed at a close distance at the bottom of the inverter body, which is convenient for operators to work;

[0017] 2. The present invention provides an outdoor power-saving inverter. When it rains during outdoor use, the second trough collects rainwater, which is discharged from the water leakage hole and impacts the water baffle. The water baffle drives the driving rod to rotate, and the driving rod drives the eccentric wheel to rotate. When the eccentric wheel rotates, it drives a plurality of swing plates to swing up and down. When the exhaust fan is working, the airflow passes through the first filter screen and enters the interior of the box body, and is discharged from the exhaust fan. The airflow can take out the heat inside the box body. At the same time, the swinging swing plate allows the airflow to swing up and down when entering the interior of the box body, thereby making the airflow more fluid, so that the airflow acting on the inverter body can take away more heat, that is, the heat dissipation effect is better;

[0018] 3. The present invention provides an outdoor power-saving inverter. The first tank body can also collect rainwater, so that the rainwater flows from the water leakage tank to the inside of the second tank body, thereby improving the efficiency of collecting rainwater, thereby ensuring the working efficiency of the swing plate and improving the heat dissipation effect. The first floor and the second bottom plate can be arranged so that the rainwater collected by the first tank body and the second tank body can quickly flow to the water leakage tank and the water leakage hole;

[0019] 4. The present invention provides an outdoor power-saving inverter. When it rains during outdoor use, the right side wall of the second frame is inclined, and the vertical plate at the bottom of the second frame can prevent rainwater from entering the second frame. At the same time, the third frame can block the water flow when the second trough is flooded, preventing the water flow from flowing to the right opening of the second frame.

[0020] 5. The present invention provides an outdoor power-saving inverter. When the operator opens the movable door, the movable door drives the horizontal plate to flip away from the buffer head. At this time, the movable plate is no longer pressed by the horizontal plate. The movable plate moves forward under the action of the spring. The movable plate drives the scraper to move through the connecting rod. The scraper moves to scrape the impurities on the top of the second filter screen to the front side of the inner cavity of the second tank body. After that, the operator only needs to clean the impurities on the front side of the inner cavity of the second tank body without removing the impurities from the second filter screen. This makes the operation of cleaning the second filter screen more convenient and is bound to the operation of opening the movable door, thus killing two birds with one stone.

[0021] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.

[0046] When disassembling the inverter body 12, the operator uses an external tool to screw the two nuts 23 on the front side, and the nuts 23 drive the threaded tube 20 to rotate in the inner cavity of the first bearing 22. The threaded rod 19 drives the adjacent clamping plate 17 to move away from the mounting plate 15 relative to the threaded tube 20 under the action of the thread.

The clamping plate 17 moves away from the slot 18, stops rotating the nuts 23, and then moves forward sideways. The inverter body 12 is moved, and the inverter body 12 drives the two mounting plates 15 to move on the top of the support plate 16, and the mounting plates 15 are moved to the clamping plate 17 away from the rear side, thereby releasing the fixing of the mounting plates 15, and then the inverter body 12 is moved upward, so that the mounting plates 15 move to the top away from the clamping plate 17, and then the inverter body 12 is moved to the front side until the inverter body 12 moves away from the box body 1, thereby completing the disassembly operation of the inverter body 12, and the operation of installing the inverter body 12 is opposite to the above;

[0047] When it is necessary to adjust the front and rear position of the inverter body 12 in the horizontal direction and adjust the position of the inverter body 12 to be close to the front side of the box body 1, the operator first screws the two nuts 23 on the front side with an external tool to move the two clamping plates 17 on the front side away from the mounting plate 15, and then screws the two nuts 23 on the rear side with an external tool to move the two clamping plates 17 on the rear side to the front side, and the clamping plate 17 drives the mounting plate 15 to move, and the mounting plate 15 moves on the top of the support plate 16, and the mounting plate 15 drives the inverter body 12 to move forward until the mounting plate 15 moves to the front side of the clamping plate 17 and is clamped in the adjacent inner cavity of the clamping slot 18, thereby mounting the inverter body 12.

When the movable door 2 is closed, the cross plate 48 of the movable door 2 is first connected to the second filter screen 42. The buffer head 47 contacts, and then as the movable door 2 continues to flip, the cross plate 48 drives the buffer head 47 to move backward, and the buffer head 47 drives the movable plate 45 to move backward to the original position through the cross bar 46, thereby making the scraper 43 move to the original position, and the spring 52 continues to be in a compressed state, and then the insertion rod 8 is moved, and the insertion rod 8 is passed through the first ring 5 and the second ring 6 to fix the movable door 2. After that, the operator can concentrate on cleaning the impurities on the front side of the inner cavity of the second trough body 40 without removing the impurities from the second filter screen 42, thereby making the operation of cleaning the second filter screen 42 more convenient and bound to the operation of opening the movable door 2, killing two birds with one stone.

[0056] Working principle: When the movable door 2 needs to be turned over, the operator moves the first frame 7 upwards, and the first frame 7 drives the insertion rod 8 to move upwards, and the insertion rod 8 moves upwards away from the first ring 5 and the second ring 6, so as to unfasten the first ring 5 and the second ring 6, and then unfasten the movable door 2, and then pull the fixing rod 4 to drive the movable door 2 to rotate around the hinge 3, so as to facilitate the operation of the inverter body 12 inside the box 1;

[0057] When disassembling the inverter body 12, the operator uses an external tool to screw the two nuts 23 on the front side, and the nuts 23 drive the threaded tube 20 to rotate in the inner cavity of the first bearing 22. The threaded rod 19 drives the adjacent clamping plate 17 to move away from the mounting plate 15 relative to the threaded tube 20 under the action of the thread. Because the bottom of the clamping plate 17 and the top of the support plate 16 fit each other, the clamping plate 17 will not rotate with the threaded tube 20. The clamping plate 17 moves away from the slot 18, stops rotating the nuts 23, and then moves forward sideways. The inverter body 12 is moved, and the inverter body 12 drives the two mounting plates 15 to move on the top of the support plate 16, and the mounting plates 15 are moved to the clamping plate 17 away from the rear side, thereby releasing the fixing of the mounting plates 15, and then the inverter body 12 is moved upward, so that the mounting plates 15 move to the top away from the clamping plate 17, and then the inverter body 12 is moved to the front side until the inverter body 12 moves away from the box body 1, thereby completing the disassembly operation of the inverter body 12, and the operation of installing the inverter body 12 is opposite to the above;

[0058] When it is necessary to adjust the front and rear position of the inverter body 12 in the horizontal direction and adjust the position of the inverter body 12 to be close to the front side of the box body 1, the operator first screws the two nuts 23 on the front side with an external tool to move the two clamping plates 17 on the front side away from the mounting plate 15, and then screws the two nuts 23 on the rear side with an external tool to move the two clamping plates 17 on the rear side to the front side, and the clamping plate 17 drives the mounting plate 15 to move, and the mounting plate 15 moves on the top of the support plate 16, and the mounting plate 15 drives the inverter body 12 to move forward until the mounting plate 15 moves to the front side of the clamping plate 17 and is clamped in the adjacent inner cavity of the clamping slot 18, thereby mounting the inverter body 12. The plate 15 is fixed, and then the inverter body 12 is fixed, so as to adjust the front and rear position of the inverter body 12 in the horizontal direction, and adjust the position of the inverter body 12 to be close to the front side of the box body 1. When the position of the inverter body 12 needs to be adjusted to be close to the rear side wall of the box body 1, the operation is opposite to the above. By adjusting the position of the inverter body 12, the internal space of the box body 1 is reasonably utilized to avoid the rear space of the inverter body 12 being too large and causing space waste. At the same time, by adjusting the position of the inverter body 12 to be close to the front side of the box body 1, the wiring operation can also be performed at a close distance at the bottom of the inverter body 12, which is convenient for operators to work;

[0059] When it rains during outdoor use, the second trough 40 collects rainwater, which is discharged from the leaking hole 53, passes through the drain pipe 38, and impacts the water baffle 39, which drives the driving rod 35 to rotate, and the driving rod 35 rotates in the inner cavity of the second bearing 36, and the driving rod 35 drives the eccentric wheel 33 to rotate, and the eccentric wheel 33 drives the second connecting plate 32 to move up and down through the third rotating rod 34, and at the same time, the two ends of the second connecting plate 32 rotate around the third rotating rod 34 and the adjacent second rotating rod 31 as the center, and the second connecting plate 32 drives the top swing plate 28 to swing up and down around the first rotating rod 29 as the center, and the top swing plate 28 is driven by the third rotating rod 34. The first connecting plate 30 drives the plurality of swinging plates 28 below to swing up and down, and the two ends of the first connecting plate 30 rotate respectively with the adjacent second rotating rod 31 as the center, that is, the eccentric wheel 33 rotates to drive the plurality of swinging plates 28 to swing up and down. When the exhaust fan 54 is working, the airflow passes through the first filter screen 26 and enters the interior of the box body 1, and is discharged from the exhaust fan 54. The airflow can take out the heat inside the box body 1. At the same time, the swinging swinging plate 28 allows the airflow to swing up and down when entering the interior of the box body 1, thereby making the airflow more fluid, so that the airflow acting on the inverter body 12 can take away more heat, that is, the heat dissipation effect is better;

[0060] When it rains during outdoor use, the right side wall of the second frame 24 is inclined, and the vertical plate 27 at the bottom of the second frame 24 can prevent rainwater from entering the second frame 24. At the same time, the third frame 25 can prevent the second trough 40 from being flooded, and the third frame 25 can block the water flow to prevent the water flow from flowing to the right opening of the second frame 24.

[0061] The first trough 9 can also collect rainwater, so that the rainwater flows from the water leakage trough 11 to the inside of the second trough 40, thereby improving the efficiency of collecting rainwater, thereby ensuring the working efficiency of the swing plate 28 and improving the heat dissipation effect. The first floor 10 and the second bottom plate 41 can make the rainwater collected by the first trough 9 and the second trough 40 flow quickly and concentratedly to the water leakage trough 11 and the water leakage hole 53;

[0062] The second filter screen 42 can filter out impurities to prevent impurities from clogging the drain pipe 38. When the operator opens the movable door 2, the movable door 2 drives the cross plate 48 to flip away from the buffer head 47. At this time, the movable plate 45 is no longer under the pressure of the cross plate 48. The movable plate 45 moves forward under the action of the spring 52. The movable plate 45 moves on the outer edge of the limit rod 50. The movable plate 45 drives the buffer head 47 to move forward through the cross bar 46. The movable plate 45 drives the scraper 43 to move through the connecting rod 44. The scraper 43 moves to scrape the impurities on the top of the second filter screen 42 to the front side of the inner cavity of the second trough 40. When the movable door 2 is closed, the cross plate 48 of the movable door 2 is first connected to the second filter screen 42. The buffer head 47 contacts, and then as the movable door 2 continues to flip, the cross plate 48 drives the buffer head 47 to move backward, and the buffer head 47 drives the movable plate 45 to move backward to the original position through the cross bar 46, thereby making the scraper 43 move to the original position, and the spring 52 continues to be in a compressed state, and then the insertion rod 8 is moved, and the insertion rod 8 is passed through the first ring 5 and the second ring 6 to fix the movable door 2. After that, the operator can concentrate on cleaning the impurities on the front side of the inner cavity of the second trough body 40 without removing the impurities from the second filter screen 42, thereby making the operation of cleaning the second filter screen 42 more convenient and bound to the operation of opening the movable door 2, killing two birds with one stone.
