Description

Technical Field

[0002] An inverter is a converter that converts DC power into constant frequency and voltage or frequency and voltage regulated AC power. Existing inverters have a variety of trigger mechanisms, including fixed angle control, lead triggering and lagging triggering. The combination of multiple triggering mechanisms leads to an increase in the number of electronic components in the inverter, and the inverter generates a lot of heat during operation. Excessive heat can cause damage to the inverter and reduce safety.

[0003] Chinese patent announcement number CN218587509U discloses a safe and reliable photovoltaic inverter box and photovoltaic inverter, including a photovoltaic inverter box body, the inner surface of which is mounted with the photovoltaic inverter body, the side wall of which is provided with heat dissipation holes, the side wall of which is provided with a heat dissipation device, the heat dissipation device including a fan, the fan being slidably connected to the side wall of the photovoltaic inverter box body, the arc surface of the fan being fixedly connected with two support rods, the ends of the two support rods being fixedly connected with photovoltaic panels away from the fans, the photovoltaic panels being electrically connected with connecting wires on the side close to the supporting rods, and the ends of the connecting wires being electrically connected with the fans away from the photovoltaic panels.

[0004] The above scheme improves the heat dissipation effect of the inverter, but installing a fan in the inverter and arranging a photovoltaic panel on the upper part of the inverter to power the fan has limitations. In order to ensure the heat dissipation effect, the fan needs to run continuously. On rainy days, the power conversion efficiency of the photovoltaic panel is low and the fan cannot be powered continuously. In the southern region, it rains a lot in summer, and it is hot and humid. The fan runs intermittently, which will inevitably lead to the heat in the inverter cannot be discharged in time. The open inverter structure will also cause the humidity in the inverter to be high, and the electronic components in the inverter are easily damaged. Summary of the invention

By arranging a water cooling unit and a sealing unit, the water cooling unit and the air cooling unit can be operated alternately on rainy days and non-rainy days.

When it starts to rain outside, the air cooling unit stops running, and the sealing unit is closed at the same time. The air cooling unit no longer blows out the air in the shell. At the same time, the water pump is started, and the water stored in the collection shell flows into the water cooling pipe through the input end of the water cooling pipe. The water cooling pipe is used to cool the electronic components in the shell, and the outside air is no longer discharged into the shell. At the same time, the inside of the shell is isolated from the outside through the sealing unit, so that the connection between the inside of the shell and the outside is avoided, and the influence of the high humidity outside air on the electronic components in the shell is avoided, thereby reducing the connection time between the inside of the inverter shell and the outside.

[0010] Preferably, an extension groove is provided on the side of the bracket along the width direction of the bracket, an extension rod is slidably arranged in the extension groove along the extension direction of the extension groove, and the end of the extension rod located outside the extension groove is hinged to the upper part of the lifting rod.

[0011] Preferably, a driving unit for driving the solar panel to rotate is provided on the bracket, and the solar panel located on the bracket has a power generation mode and a water collection mode. In the power generation mode, the upper end surface of the solar panel is coplanar with the upper end surface of the bracket, and in the water collection mode, there is an angle between the upper end surface of the solar panel and the upper end surface of the bracket.

[0012] Preferably, a trigger button is provided above the float, and the trigger button is fixedly provided on the lifting shell.

[0015] Preferably, the air cooling unit includes a plurality of fans arranged along the width direction of the shell, and the fans are divided into two parts, one part of the fans blows outside air into the shell, and the other part of the fans draws air out of the shell.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a water-cooling unit and a sealing unit so that the water-cooling unit and the air-cooling unit can operate alternately on rainy days and non-rainy days. When in use, if it does not rain outside, the air-cooling unit is in operation and the water-cooling unit is in shutdown.

The water stored in the collection shell flows into the water-cooling pipe through the input end of the water-cooling pipe. The water-cooling pipe is used to cool the internal space of the shell, and the outside air is no longer discharged into the shell. At the same time, the interior of the shell is isolated from the outside through the sealing unit, so that the connection between the interior of the shell and the outside is avoided, and the influence of the high humidity outside air on the electronic components in the shell is avoided. In this way, the connection time between the inside of the inverter shell and the outside is reduced, the service life of the inverter is extended, and the safety of the inverter during use is guaranteed.

[0017] 2. By setting a lifting unit, when it rains outside, the lifting unit will first collect rainwater, and the water gathered in the lifting shell will lift the float up, and the float will push the bracket to rotate through the lifting rod and the connecting assembly. When the float has not risen to the highest position, the solar panel on the bracket will not rotate at all. In this way, when rain from the outside falls on the solar panel, the rainwater can fall along the inclined end surface formed on the upper part of the solar panel. In this way, before the solar panel flips over, the dust on the upper part of the solar panel will be washed away by the rainwater. As the float continues to rise, when the float triggers the trigger button, the driving unit drives the solar panel to rotate, and the solar panel no longer blocks the opening of the collecting shell, and the rainwater from the outside can flow into the collecting shell smoothly, avoiding the dust on the solar panel being brought into the collecting shell when the rainwater falls into the collecting shell.

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1 and Figure 2, which is a schematic diagram of the structure of the safety inverter based on multiple trigger mechanisms in this embodiment. The safety inverter in this embodiment includes a shell 1 and an air cooling unit 2 arranged on one side of the shell 1; a water cooling unit 3 is also arranged on the shell 1, and the water cooling unit 3 includes a collecting shell 31 arranged above the shell 1, and an opening is arranged on the upper part of the collecting shell 31, and rainwater from the outside enters the collecting shell 31 through the opening. A water cooling pipe 32 is arranged on one side of the collecting shell 31, and the input end and the output end of the water cooling pipe 32 are both arranged on the side wall of the collecting shell 31 and are connected to the collecting shell 31. It is worth noting that the water cooling pipe 32 extends into the shell 1 and divides the shell 1 in the vertical direction. There are two cavities, the end of the water-cooling pipe 32 passes through the shell 1 and is connected to the collecting shell 31. The cavity is used to place electronic components. A water pump 33 is arranged on the water-cooling pipe 32. The water pump 33 draws water in the collecting shell 31 into the water-cooling pipe 32, and the water is discharged back to the collecting shell 31 after circulation through the water-cooling pipe 32. The water-cooling pipe 32 absorbs the heat generated by the electronic components in the cavity to reduce the temperature of the electronic components. In this embodiment, a sealing unit 4 is arranged in the shell 1. The sealing unit 4 separates the water-cooling unit 3 and the air-cooling unit 2. When air cooling is required, the sealing unit 4 is opened and the air-cooling unit 2 is started alone. When water cooling is required, the sealing unit 4 is closed and the water-cooling unit 3 is started alone.

[0033] When the inverter is used daily, some inverters are outdoors for a long time. The high temperature generated by the inverter during operation needs to be removed in time. Most inverters are provided with an air cooling unit 2 to improve the heat dissipation effect. Compared with the heat dissipation method of only opening heat dissipation holes, the heat dissipation effect of the inverter can be improved by using the air cooling unit 2, but the energy consumption is relatively high. Therefore, a solar module 5 is also provided on the upper part of some inverters to provide electric energy for the air cooling unit 2. However, depending on the use environment, the air cooling unit 2 also has certain disadvantages. When the air cooling unit 2 cools down the inverter, the inside of the inverter housing 1 is connected to the outside world, so that the air cooling unit 2 can take out the heat in the inverter housing 1. If the humidity in the outside air is high, although the air cooling unit 2 can dissipate the heat for the air in the inverter housing 1, it will also cause the humidity in the inverter housing 1 to increase. Excessive humidity will inevitably affect the electronic components in the housing 1, resulting in a reduction in the service life of the electronic components, and then cause the inverter to short-circuit when in use, and the safety is poor.

[0034] In order to avoid the above situation, a water cooling unit 3 is added to the housing 1 in this embodiment, and since the water cooling unit 3 also requires electric energy to drive, in order to reduce energy consumption, the water cooling unit 3 and the air cooling unit 2 will not operate at the same time. The specific structure and working process of this inverter are as follows: When in use, if it is not raining outside, the air cooling unit 2 is in operation, the water cooling unit 3 is in shutdown, the sealing unit 4 is opened, the inside of the shell 1 is connected with the outside, and the air cooling unit 2 blows out the heat in the shell 1, thereby achieving a heat dissipation effect. When it starts to rain outside, the air cooling unit 2 stops running, and the sealing unit 4 is closed. The air cooling unit 2 no longer blows out the air in the shell 1, and the outside air is no longer discharged into the shell 1. At the same time, the inside of the shell 1 is isolated from the outside through the sealing unit 4, which prevents the inside of the shell 1 from being connected with the outside, and also prevents the high humidity outside air from affecting the electronic components in the shell 1. In order to reduce the impact caused, after the air cooling unit 2 stops running, the water pump 33 is started, and the water stored in the collecting shell 31 flows into the water cooling pipe 32 through the input end of the water cooling pipe 32, so that the water flowing in the water cooling pipe 32 can take away the heat in the shell 1, thereby achieving cooling. Moreover, since an opening is provided above the collecting shell 31 for collecting rainwater, when it stops raining outside, the sealing unit 4 is opened again, the water cooling unit 3 stops running, and the air cooling unit 2 is restarted, thereby reducing the connection time between the inside of the inverter shell 1 and the outside world, extending the service life of the inverter, and ensuring the safety of the inverter during use.

[0035] Reference Figure 6 and Figure 7 : A solar energy assembly 5 is arranged above the collecting shell 31. The solar energy assembly 5 includes a bracket 51 arranged above the collecting shell 31. The bracket 51 is made of a lightweight material. A plurality of solar panels 52 are arranged on the bracket 51. The electric energy collected by the solar panels 52 is used to power the air cooling unit 2 and the water cooling unit 3.

[0036] Reference Figure 6 and Figure 7 A lifting unit 53 is provided on one side of the shell 1, and one end of the bracket 51 is hinged to the upper part of the collecting shell 31. The lifting unit 53 includes a lifting shell 531 provided on one side of the shell 1, and a float 532 is provided in the lifting shell 531 for movement in the vertical direction. An inlet is vertically penetrated through the float 532, and a lifting rod 533 is vertically fixed on the upper part of the float 532. The lifting rod 533 is made of lightweight material, and a connecting assembly is provided on the bracket 51. When the lifting rod 533 is lifted or lowered in the vertical direction, the bracket 51 is pushed to rotate around the hinge between the bracket 51 and the collecting shell 31 through the connecting assembly.

[0037] Reference Figure 5 An extension groove is provided on the side of the bracket 51 along the width direction of the bracket 51, and an extension rod 534 is slidably arranged in the extension groove along the extension direction of the extension groove. The end of the extension rod 534 located outside the extension groove is hinged to the upper part of the lifting rod 533.

[0038] Reference Figure 2 and Figure 3: A driving unit 54 for driving the solar panel 52 to rotate is arranged on the bracket 51. The solar panel 52 located on the bracket 51 has a power generation mode and a water collection mode. In the power generation mode, the upper end surface of the solar panel 52 is coplanar with the upper end surface of the bracket 51. In the water collection mode, there is an angle between the upper end surface of the solar panel 52 and the upper end surface of the bracket 51, and the solar panel 52 is tilted downward toward the hinge between the bracket 51 and the collecting shell 31.

[0039] The driving unit 54 includes a rotary driver 541 and a synchronous component. A plurality of solar panels 52 are arranged on the bracket 51. A synchronous component is arranged between adjacent solar panels 52. A rotary driver 541 for driving the solar panel 52 to rotate is arranged at the end of one of the solar panels 52. The synchronous component includes a synchronous wheel 542 and a synchronous belt 543. The synchronous wheel 542 is arranged at the end of the solar panel 52. The synchronous wheels 542 at the ends of adjacent solar panels 52 are connected through transmission by the synchronous belt 543. The synchronous wheels 542 are respectively arranged at the ends of two adjacent solar panels 52. The synchronous belt 543 is sleeved on the two synchronous wheels 542. The synchronous belt 543 cooperates with the synchronous wheel 542 in transmission. The extension rod 534 is also made of lightweight material. At the same time, the lifting rod 533, the extension rod 534 and the bracket 51 are all made of lightweight material, which ensures that the rainwater in the lifting shell can lift the float 532, so that the bracket 51 can rotate around the hinge between the bracket 51 and the collecting shell 31.

[0040] Reference Figure 8 : A trigger button 55 is arranged above the float 532, and the trigger button 55 is fixedly arranged on the lifting shell 531. When the float 532 moves to the highest point in the vertical direction, the trigger button 55 is triggered, the driving unit 54 is activated and started, and the solar panel 52 switches from the power generation mode to the water collection mode.

[0041] When it is not raining outside, the water cooling unit 3 is not started, the air cooling unit 2 is started, the sealing unit 4 is in an open state, the bracket 51 is in a horizontal state, the bracket 51 is horizontally arranged above the collecting shell 31, and the solar panel 52 located on the bracket 51 is also in a horizontal state, and the solar panel 52 can generate electricity normally. When it starts to rain, the rainwater from the outside first falls into the lifting shell 531, and the upper part of the collecting shell 31 cannot receive the rainwater from the outside temporarily due to the shielding of the solar panel 52. As the rainwater in the lifting shell 531 continues to gather, the float 532 drives the lifting rod 533 to rise, and the lifting rod 533 drives the extension rod 534 to rise, thereby causing the bracket 51 to rotate, so that the bracket 51 gradually begins to tilt. When the rainwater from the outside falls on the bracket 51, the solar panel 52 located on the bracket 51 forms a The inclined end surface allows rainwater to slide down under the guidance of the inclined end surface formed by the solar panel 52, and the sliding rainwater can clean the solar panel 52. As the float 532 rises, the sealing unit 4 is gradually closed, and the air cooling unit 2 is immediately closed after the sealing unit 4 is completely closed. When the float 532 rises to the highest position, the float 532 triggers the trigger button 55, and the sealing unit 4 is completely closed. The driving unit 54 drives the solar panel 52 to rotate and tilt, and the solar panel 52 cannot cover the opening of the collection shell 31. Rainwater from the outside can smoothly enter the collection shell 31. When the trigger button 55 is triggered, the water pump 33 and the driving unit 54 are started at the same time. The water pump 33 pumps the water collected in the collection shell 31 into the water cooling pipe 32, and the water cooling pipe 32 located in the shell 1 cools the electronic components.

[0042] Reference Figure 1 , Fig.11 and Fig.12 The sealing unit 4 includes a vent 41 and a sealing plate 42. The vent 41 is opened on the side wall of the shell 1, and the sealing plate 42 is arranged at the front end of the vent 41 to move in the vertical direction. The float 532 rises and the sealing plate 42 drops; the float 532 drops and the sealing plate 42 rises. When the float 532 triggers the trigger button 55, the sealing plate 42 covers the vent 41.

[0043] Reference Fig.11 A rack 44 is vertically fixed on the float 532, a gear 43 is rotatably arranged between the rack 44 and the sealing plate 42, and meshing teeth are vertically opened on one side of the sealing plate 42 facing the gear 43, and the gear 43 meshes with the meshing teeth on the sealing plate 42 and the rack 44 respectively.

[0044] When the float 532 rises, the float 532 drives the rack 44 to rise synchronously, and the rack 44 drives the sealing plate 42 to fall through the gear 43. Similarly, when the float 532 falls, the float 532 drives the rack 44 to fall synchronously, and the rack 44 drives the sealing plate 42 to rise through the gear 43. When the rainfall outside stops, the water in the lifting shell 531 is discharged, the water level in the lifting shell 531 continues to decrease, and the float 532 drops synchronously with the water level. When all the water in the lifting shell 531 is discharged, the sealing plate 42 is fully opened, the air cooling unit 2 is started, and the water cooling unit 3 stops running. At this time, the bracket 51 rotates to a horizontal state, and the driving unit 54 drives the solar panel 52 on the bracket 51 to rotate to a horizontal state.

[0045] Reference Figure 4 The air cooling unit 2 includes a plurality of fans 21 arranged along the width direction of the shell 1. The fans 21 are divided into two parts, one part of the fans 21 blows outside air into the shell 1, and the other part of the fans 21 draws air out of the shell 1.

[0046] By arranging the fan 21 on the side wall of the housing 1, the air in the housing 1 can be discharged in time, thereby ensuring the heat dissipation effect of the inverter when it is not raining outside.

[0047] Working principle: when it is not raining outside, the water cooling unit 3 is not started, the air cooling unit 2 is started, the sealing unit 4 is in the open state, the bracket 51 is in a horizontal state, the bracket 51 is horizontally arranged above the collecting shell 31, and the solar panel 52 located on the bracket 51 is also in a horizontal state, and the solar panel 52 can generate electricity normally. When it starts to rain, the rain from the outside first falls into the lifting shell 531, and the upper part of the collecting shell 31 cannot receive the rain from the outside temporarily due to the shielding of the solar panel 52. As the rainwater in the lifting shell 531 continues to gather, the float 532 drives the lifting rod 533 to rise, and the lifting rod 533 drives the extension rod 534 to rise, thereby causing the bracket 51 to rotate, so that the bracket 51 gradually begins to tilt, and when the rainwater from the outside falls on the bracket 51, the solar panel 52 located on the bracket 51 The solar panel 52 forms an inclined end surface, and rainwater slides down under the guidance of the inclined end surface formed by the solar panel 52. The sliding rainwater can clean the solar panel 52. As the float 532 rises, the sealing unit 4 is gradually closed. The air cooling unit 2 is immediately closed after the sealing unit 4 is completely closed. When the float 532 rises to the highest position, the float 532 triggers the trigger button 55, and the sealing unit 4 is completely closed. The driving unit 54 drives the solar panel 52 to rotate and tilt. The solar panel 52 cannot cover the opening of the collection shell 31, and the rainwater from the outside can smoothly enter the collection shell 31. When the trigger button 55 is triggered, the water pump 33 and the driving unit 54 are started at the same time, and the water pump 33 pumps the water collected in the collection shell 31 into the water cooling pipe 32 to cool the shell 1.

[0048] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
