Description
Technical Field
[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to an outdoor photovoltaic inverter structure. Background Art
[0002] Photovoltaic power generation, as an important form of renewable energy, is particularly common in places with strong sunlight and hot weather. As a key device in the photovoltaic power generation system, the photovoltaic inverter plays a vital role. It can convert the direct current generated by the photovoltaic panels into alternating current that can be used by homes, enterprises or power grids. It is an important bridge connecting photovoltaic power generation and the power grid. In a hot and windy environment, the photovoltaic inverter faces severe heat dissipation challenges. An effective heat dissipation design can not only ensure the stable operation of the inverter at high temperatures, but also extend its service life and improve the efficiency and reliability of the entire photovoltaic power generation system. However, such an environment is often accompanied by dryness and strong winds and sand, which poses a considerable challenge to the heat dissipation of the photovoltaic inverter. When the wind speed increases, the sand and dust on the ground are more likely to be carried by the strong airflow and invade the heat dissipation chamber of the inverter through the heat dissipation window. The sand and dust that enter will gradually accumulate in the heat dissipation chamber, which not only weakens the efficiency of the heat dissipation system, but may also adhere tightly to the heat sink, seriously hindering the effective transfer of heat. In the long run, under the continuous high temperature environment and the continuous invasion of wind and sand, the temperature inside the inverter will rise significantly, which will pose a serious threat to its electrical performance and operational stability.
[0003] To solve this problem, Patent 202010992230.6 discloses a heat dissipation and dust prevention device for a photovoltaic inverter. It cleans the dust inside the photovoltaic inverter by setting a heat dissipation and dust prevention box. However, during the operation of the photovoltaic inverter, the external environment is constantly changing. When the wind speed increases, the sand and dust on the ground are more easily carried away by the strong airflow and invade the heat dissipation compartment of the inverter through the heat dissipation window. Manual cleaning alone cannot guarantee the heat dissipation effect of the inverter. For this reason, we propose an outdoor photovoltaic inverter structure. Summary of the invention

[0016] The present invention has at least the following beneficial effects:
[0017] 1. Protect the inverter: When the wind speed is too high, the direct wind force will drive the sand and gravel, which may damage the cooling system of the inverter or even the entire equipment. Sealing the heat dissipation compartment with a sealing plate can effectively isolate the direct impact of high-speed wind flow and sand and gravel, and protect the electronic components inside the inverter from damage.
[0018] 2 Intelligent heat dissipation: While sealing the heat dissipation chamber, connect the heat dissipation chamber with the air guide chamber, and use the Bernoulli effect, that is, the pressure is low where the flow rate is high, to enhance the heat dissipation effect. When high-speed airflow passes through the air guide chamber, a low-pressure area will be formed at the opening of the heat dissipation chamber, thereby attracting the hot air in the heat dissipation chamber to be discharged, achieving efficient heat dissipation.
[0019] 3. Improve heat dissipation efficiency: Traditional heat dissipation methods may rely on natural convection or fixed fans, and their heat dissipation efficiency is limited by environmental conditions. This design can dynamically adjust the heat dissipation strategy according to changes in wind speed, and use high-speed wind flow in the environment to enhance the heat dissipation effect, thereby improving heat dissipation efficiency.
[0020] 4 Energy saving and consumption reduction: Since this design utilizes the natural wind resources in the environment to assist in heat dissipation, it can reduce the energy consumption of the inverter's own cooling system. When the wind speed is sufficient, it may even rely entirely on natural wind power for heat dissipation, thereby achieving the goal of energy saving and consumption reduction.

DETAILED DESCRIPTION
[0033] 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.
[0034] Example 1: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: an outdoor photovoltaic inverter structure, including an inverter body 1 and a heat dissipation bin 2, and also including an air guide bin 3, the air guide bin 3 is arranged on the heat dissipation bin 2, and the air guide bin 3 penetrates the heat dissipation bin 2; a sealing plate 4, the sealing plate 4 is installed in the heat dissipation bin 2, and the sealing plate 4 is provided with multiple; an anemometer 78, the anemometer 78 is arranged on the heat dissipation bin 2.
[0035] A protective heat dissipation unit 5 is provided in the heat dissipation bin 2, and the sealing plate 4 is connected to the protective heat dissipation unit 5. The heat in the heat dissipation bin 2 is discharged through the protective heat dissipation unit 5, and when the wind and sand in the external environment become stronger, the sealing plate 4 is driven to move by the protective heat dissipation unit 5 to seal the heat dissipation window on the heat dissipation bin 2. An anemometer 78 is provided on the heat dissipation bin 2, and the anemometer 78 has a built-in sensor.
[0036] The advantage of setting up the protective heat dissipation unit 5 is that the sealing plate 4 can be used to seal the heat dissipation window on the heat dissipation chamber 2 of the inverter when strong winds cause strong sandstorms outside. When the wind speed is too high, the direct wind force may drive the sand and gravel to cause damage to the heat dissipation system of the inverter or even the entire equipment. The heat dissipation chamber 2 is sealed by the sealing plate 4, which can effectively isolate the direct impact of high-speed wind flow and sand and gravel, and protect the electronic components inside the inverter from damage. At the same time, the design of the sealing plate 4 can effectively block the wind and sand from entering the heat dissipation window of the inverter, avoiding the erosion and damage of the electronic components inside the inverter by the wind and sand, and extending the service life of the inverter. In addition, the intrusion of wind and sand may cause the internal temperature of the inverter to rise abnormally, thereby affecting its electrical performance and operating stability. The design of the sealing plate 4 helps to maintain the stability of the internal environment of the inverter, ensuring that the equipment can still operate stably under severe weather conditions.
[0037] The heat dissipation compensation unit 9 is arranged on the air guide bin 3 at any time. After the sealing plate 4 seals the heat dissipation window on the heat dissipation bin 2, the heat in the heat dissipation bin 2 is discharged through the heat dissipation compensation unit 9.
[0038] The benefit of the heat dissipation compensation unit 9 is that when the heat dissipation window of the heat dissipation bin 2 is sealed, the air guide bin 3 can be connected to the heat dissipation bin 2 so that the air guide bin 3 can be used for heat dissipation. The Bernoulli effect points out that in a fluid such as air, the pressure is low where the flow rate is large, and the pressure is high where the flow rate is small. This design introduces airflow through the air guide bin 3 to form a high-speed airflow area in the air guide bin 3. The low pressure characteristics of this area are utilized to effectively take away the heat in the heat dissipation bin 2 connected to the air guide bin 3. The design of the air guide bin 3 can guide the airflow to flow through the heat dissipation bin 2 more efficiently, ensuring that the heat can be quickly taken away by the airflow and dissipated into the environment, which helps to reduce the temperature in the heat dissipation bin 2 and improve the heat dissipation efficiency. In the case of sealing the heat dissipation window, using the Bernoulli effect for heat dissipation can ensure that the inverter will not fail or shut down due to overheating in harsh environments, which helps to improve the stability and reliability of the equipment, reduce the downtime and maintenance costs caused by heat dissipation problems, and enable the inverter to better adapt to various complex environments, such as areas with strong winds and sand, high temperature and humid environments, etc. In these environments, the inverter can still maintain stable heat dissipation performance to ensure the normal operation of the equipment.
[0039] The protective heat dissipation unit 5 includes a heat dissipation element 6 arranged in the heat dissipation bin 2, and the heat dissipation element 6 is used to discharge the heat in the heat dissipation bin 2. A driving element 7 is arranged on the heat dissipation element 6, and the driving element 7 is used to drive the sealing plate 4 to seal the heat dissipation window on the heat dissipation bin 2. A power element 8 is arranged in the heat dissipation bin 2, and the power element 8 is used to provide power for the heat dissipation element 6 and the driving element 7 to work.

[0041] The driving member 7 includes a sliding groove 71 opened on the fixed plate 61, and the sliding groove 71 is slidably connected to the sealing plate 4. A sliding block 72 is slidably arranged in the sliding groove 71, and an extension rod 73 is arranged on the sliding block 72. One end of the extension rod 73 is connected to the sealing plate 4. A plurality of driving screw rods 74 are arranged in the heat dissipation bin 2, and the driving screw rods 74 pass through a plurality of sliding blocks 72, and the sliding block 72 is threadedly connected to the driving screw rod 74. A positioning shaft 75 is rotatably arranged in the heat dissipation bin 2, and a driving pulley 76 is arranged on the positioning shaft 75 and the driving screw rod 74, and a driving belt 77 is arranged on the driving pulley 76.
[0042] The advantage of the drive member 7 is that the sealing plate 4 can be used to seal the heat dissipation window on the heat dissipation compartment 2 of the inverter when strong winds cause heavy sandstorms. When the wind speed is too high, the direct wind force may drive the sand and gravel to cause damage to the heat dissipation system of the inverter or even the entire device. By sealing the heat dissipation compartment 2 with the sealing plate 4, the direct impact of high-speed wind flow and sand and gravel can be effectively isolated, thereby protecting the electronic components inside the inverter from damage.
[0043] The power part 8 includes a moving groove 81 arranged in the heat dissipation bin 2, a moving plate 82 is slidably arranged in the moving groove 81, an electric push rod 83 is arranged in the moving groove 81, one end of the electric push rod 83 is connected to the moving plate 82, a motor 84 is arranged on the moving plate 82, a driving shaft 85 is rotatably arranged on the moving plate 82, a driving gear 1 86 is arranged on the driving shaft 66, and a driving gear 2 87 engaged with the driving gear 1 86 is arranged on the driving shaft 85.
[0044] When the wind speed detected in the external environment exceeds the standard value, the sensor in the anemometer 78 sends a signal, and the motor 84 is controlled to stop working through the program and the controller, and the electric push rod 83 is synchronously driven to drive the moving plate 82, the motor 84 and the drive shaft 85 connected to the motor 84 and the drive gear 2 87 to disengage from the drive gear 1 86 located on the active shaft 66. The shutdown of the motor 84 and the operation of the electric push rod 83 are both controlled by the program, which is the prior art.
[0045] When the movable plate 82 moves, the pushing plate 88 connected thereto is driven to move synchronously. During the movement of the pushing plate 88, the pushing latch 89 arranged thereon is driven to move synchronously. When the pushing latch 89 moves, the pushing gear 810 engaged therewith is driven to rotate synchronously. The rotation of the pushing gear 810 drives the positioning shaft 75 connected thereto to rotate synchronously. The rotation of the positioning shaft 75 drives the driving pulley 76 arranged thereon to rotate. The rotation of the driving pulley 76 drives the driving pulley 76 on the driving screw 74 to rotate synchronously through the driving belt 77, thereby driving the driving screw 74 connected to the driving pulley 76 to rotate. The rotation of the driving screw 74 drives the moving block threadedly connected thereto to move in the sliding groove 71. The movement of the moving block synchronously drives the sealing plate 4 to move through the extension rod 73 until the sealing plate 4 completes the sealing of the heat dissipation window.
[0046] The heat dissipation compensation unit 9 includes a flow guide member 10 arranged on the air guide bin 3, and the flow guide member 10 is used to guide the airflow through the air guide bin 3. A switching member 11 is arranged on the air guide bin 3, and the switching member 11 is used to change the connection state between the air guide bin 3 and the heat dissipation bin 2. A spoiler 12 is arranged in the heat dissipation bin 2, and the spoiler 12 is used to disturb the airflow in the heat dissipation bin 2.
[0047] The guide member 10 includes a discharge bin 101 arranged on the air guide bin 3, filter plates 102 are arranged at both ends of the air guide bin 3, the filter plates 102 are inclined, and a discharge groove 103 is opened on one side of the filter plate 102 of the air guide bin 3, and the discharge groove 103 is connected to the discharge bin 101.
[0048] The advantage of setting up the guide member 10 is that it can discharge the sand and gravel intercepted by the filter plate 102 out of the air guide bin 3, and the inclined design of the filter plate 102 makes it easier for the sand and gravel intercepted by it to enter the discharge bin 101, and then the sand and gravel are taken out of the discharge bin 101 by the high-speed airflow in the discharge bin 101.
[0049] The switching member 11 includes through grooves 111 arranged on both sides of the air guide bin 3, and closing plates 112 are arranged on both sides of the air guide bin 3 at the positions of the through grooves 111, and conducting plates 113 are arranged on the closing plates 112, and a lifting plate 115 is arranged on the driving screw rod 74, and the lifting plate 115 is threadedly connected to the driving screw rod 74, and the lifting plate 115 is connected to multiple closing plates 112.
[0050] The advantage of setting the switching component 11 is that the air guide compartment 3 can be connected with the heat dissipation compartment 2 after the heat dissipation window of the heat dissipation compartment 2 is sealed, and then the air flow is introduced through the air guide compartment 3 to form a high-speed airflow area in the air guide compartment 3. The low-pressure characteristics of this area can be used to effectively take away the heat in the heat dissipation compartment 2 connected with the air guide compartment 3.
[0051] When the driving screw 74 rotates, the lifting rod is driven to rise synchronously, and the rising of the lifting rod drives the closing plate 112 to rise synchronously. At this time, the through groove 111 opened on the air guide bin 3 is separated from the closing plate 112 and connected with the conducting plate 113, so that the air guide bin 3 is connected with the heat dissipation bin 2. When the air guide bin 3 introduces airflow, a high-speed airflow area is formed in the air guide bin 3. By utilizing the low-pressure characteristics of this area, the heat in the heat dissipation bin 2 connected with the air guide bin 3 is effectively taken away through the through groove 111.
[0052] At the same time, when the airflow enters the air guide bin 3, the sand and gravel carried in the airflow will be intercepted by the filter plate 102 and fall into the discharge bin 101 through the discharge slot 103, and the sand and gravel will be taken out by the airflow in the discharge bin 101. During the continuous circulation of the airflow, the power blades 123 are driven to rotate, and the rotation of the power blades 123 drives the rotation of the rotating shaft 122. The rotation of the rotating shaft 122 drives the transmission gear 1 124 arranged thereon to rotate, and the rotation of the transmission gear 1 124 drives the transmission gear 2 126 arranged on the transmission shaft 125 to rotate, and the rotation of the transmission gear 2 126 drives the transmission shaft 125 to rotate. When the transmission shaft 125 rotates clockwise, When the transmission shaft 125 rotates counterclockwise, it drives the switch gear plate 128 to rotate clockwise, and drives the switch shaft 129 to rotate through the ratchet 1213 on the switch gear plate 128, thereby driving the driving shaft 66 to rotate; when the transmission shaft 125 rotates counterclockwise, it drives the switch gear plate 128 to rotate counterclockwise, and the switch gear plate 128 rotates counterclockwise to drive the reversing gear 1215 to rotate, and the reversing gear 1215 rotates to drive the switch gear plate 2 1210 to rotate, and the switch gear plate 2 1210 rotates to drive the ratchet 1213 set thereon to rotate, thereby driving the ratchet wheel 1211 to rotate, and then drives the switch shaft 129 to rotate, and further drives the driving shaft 66 to rotate.
[0053] The driving shaft 66 rotates to drive the power gear 1 67 disposed thereon to rotate, and the power gear 1 67 rotates to drive the power gear 2 68 disposed on the rotating shaft 64 to rotate, thereby driving the rotating shaft 64 to rotate, and the rotation of the rotating shaft 64 drives the heat dissipation blades 65 to rotate, thereby disturbing the airflow in the heat dissipation bin 2.
[0054] During use, when the wind speed detected in the external environment exceeds the standard value, the sensor in the anemometer 78 sends a signal, and the motor 84 is controlled to stop working through the program and the controller, and the electric push rod 83 is synchronously driven to drive the moving plate 82, the motor 84 and the drive shaft 85 connected to the motor 84 and the drive gear 2 87 to disengage from the drive gear 1 86 located on the active shaft 66. The shutdown of the motor 84 and the operation of the electric push rod 83 are both controlled by the program, which is the prior art.
[0055] When the movable plate 82 moves, the pushing plate 88 connected thereto is driven to move synchronously. During the movement of the pushing plate 88, the pushing latch 89 arranged thereon is driven to move synchronously. When the pushing latch 89 moves, the pushing gear 810 engaged therewith is driven to rotate synchronously. The rotation of the pushing gear 810 drives the positioning shaft 75 connected thereto to rotate synchronously. The rotation of the positioning shaft 75 drives the driving pulley 76 arranged thereon to rotate. The rotation of the driving pulley 76 drives the driving pulley 76 on the driving screw 74 to rotate synchronously through the driving belt 77, thereby driving the driving screw 74 connected to the driving pulley 76 to rotate. The rotation of the driving screw 74 drives the moving block threadedly connected thereto to move in the sliding groove 71. The movement of the moving block synchronously drives the sealing plate 4 to move through the extension rod 73 until the sealing plate 4 completes the sealing of the heat dissipation window.
[0056] When the driving screw 74 rotates, the lifting rod is driven to rise synchronously, and the rising of the lifting rod drives the closing plate 112 to rise synchronously. At this time, the through groove 111 opened on the air guide bin 3 is separated from the closing plate 112 and connected with the conducting plate 113, so that the air guide bin 3 is connected with the heat dissipation bin 2. When the air guide bin 3 introduces airflow, a high-speed airflow area is formed in the air guide bin 3. By utilizing the low-pressure characteristics of this area, the heat in the heat dissipation bin 2 connected with the air guide bin 3 is effectively taken away through the through groove 111.

The switching shaft 129 is connected to the driving shaft 66. The switching shaft 129 is rotatably connected to the switching toothed disc 128. The switching shaft 129 is located in the switching chamber 127 and has a switching toothed disc 2 1210 at one end. The switching shaft 129 is located in the switching chamber 127 and has a plurality of ratchet wheels 1211 at one end. The ratchet wheels 1211 are respectively connected to the switching toothed disc 1. 128 and the switching gear plate 1210 are fitted together, and the switching gear plate 128 and the switching gear plate 1210 are both provided with a deflection shaft 1212, and a ratchet 1213 is rotatably provided on the deflection shaft 1212, and the ratchet 1213 is connected to the deflection shaft 1212 through a torsion spring, and a reversing shaft 1214 is rotatably provided in the switching chamber 127, and a reversing gear 1215 is provided on the reversing shaft 1214, and the reversing gear 1215 is meshed with the switching gear plate 128 and the switching gear plate 1210.
[0059] The advantage of the spoiler 12 is that it can change the flow path of the airflow, making it more complex and changeable. This helps the airflow to contact each area in the heat dissipation chamber 2 more fully, thereby taking away more heat. When the airflow is evenly distributed, each area can obtain the same airflow speed and temperature, which helps to achieve more efficient heat exchange. The spoiler 12 disturbs the airflow so that the heat is more evenly distributed in the heat dissipation chamber 2, further improving the heat exchange efficiency. At the same time, the spoiler 12 can break the laminar state of the airflow in the heat dissipation chamber 2, forming turbulence, thereby enhancing the mixing and diffusion of the airflow. This helps to quickly transfer heat from high-temperature areas to low-temperature areas and prevent the occurrence of local overheating.
[0060] When the airflow enters the air guide bin 3, the sand and gravel carried in the airflow will be intercepted by the filter plate 102 and fall into the discharge bin 101 through the discharge slot 103, and the sand and gravel will be taken out by the airflow in the discharge bin 101. During the continuous circulation of the airflow, the power blades 123 are driven to rotate, and the rotation of the power blades 123 drives the rotation of the rotating shaft 122. The rotation of the rotating shaft 122 drives the transmission gear 1 124 arranged thereon to rotate, and the rotation of the transmission gear 1 124 drives the transmission gear 2 126 arranged on the transmission shaft 125 to rotate, and the rotation of the transmission gear 2 126 drives the transmission shaft 125 to rotate. When the transmission shaft 125 rotates clockwise, The switching gear plate 128 is driven to rotate clockwise, and the switching shaft 129 is driven to rotate through the ratchet 1213 on the switching gear plate 128, thereby the driving shaft 66 is rotated. When the transmission shaft 125 rotates counterclockwise, it drives the switching gear plate 128 to rotate counterclockwise. The switching gear plate 128 rotates counterclockwise and drives the reversing gear 1215 to rotate. The reversing gear 1215 rotates and drives the switching gear plate 2 1210 to rotate. The switching gear plate 2 1210 rotates and drives the ratchet 1213 set thereon to rotate, thereby driving the ratchet wheel 1211 to rotate, and then drives the switching shaft 129 to rotate, and further drives the driving shaft 66 to rotate.
[0061] The driving shaft 66 rotates to drive the power gear 1 67 disposed thereon to rotate, and the power gear 1 67 rotates to drive the power gear 2 68 disposed on the rotating shaft 64 to rotate, thereby driving the rotating shaft 64 to rotate, and the rotation of the rotating shaft 64 drives the heat dissipation blades 65 to rotate, thereby disturbing the airflow in the heat dissipation bin 2.
