Description

Technical Field

[0001] The present invention relates to the technical field of inverter support frames, and specifically to a support frame with high heat dissipation performance for large-scale installation of inverters. Background Art

[0002] In modern society where environmental protection is increasingly emphasized, photovoltaic power generation has gradually begun to replace thermal power generation and entered people's lives. By laying photovoltaic power generation equipment over a large area, solar energy is converted into electrical energy, and pollutants emitted during the power generation process are reduced, thereby achieving the purpose of environmental protection. Photovoltaic power generation equipment needs to cooperate with an inverter to convert current between direct current and alternating current for easy storage and transmission of the current. To facilitate the installation of the inverters used in photovoltaic power generation equipment, the prior art mainly uses inverter installation support frames.

[0003] However, the prior art still has the following defects during use: 1. The integration degree of the inverter support frames in the prior art is relatively low. A single support frame can only install one inverter. As the inverter is exposed to the outdoor high-temperature environment for a long time along with the photovoltaic power generation equipment and needs to be equipped with an active heat dissipation device, after installing one inverter with a traditional support frame, a separate heat dissipation device needs to be configured for the inverter. Thus, when installing photovoltaic power generation equipment on a large scale, the installation cost of the inverter heat dissipation device is increased. 2. The inverter support frames in the prior art do not have a lightning protection function for inverters used in outdoor environments, and the practicability is not ideal. In thunderstorm weather, an inverter made of metal material and in an energized state is extremely vulnerable to lightning strikes. Lightning strikes can not only damage the outer shell of the inverter but also easily damage the circuits and electronic components inside for converting current, thus unable to ensure the safety of the photovoltaic power generation equipment and the inverter during operation.

[0004] In view of this, we propose a support frame with high heat dissipation performance for large-scale installation of inverters to solve the existing problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a support frame with high heat dissipation performance for large-scale installation of inverters to solve the technical problems existing in the prior art pointed out in the background art. The present invention provides the following technical solutions to achieve the above purpose: A support frame with high heat dissipation performance for large-scale installation of inverters includes a triangular frame, a cross beam, and a flow guide cover; a lightning protection frame is welded to the top of the triangular frame, and three support columns are fixedly installed at the bottom; a cross beam is installed between adjacent two support columns through bolts, and an installation frame is installed on the outer side of the cross beam; a flow guide cover is fixedly installed inside the triangular frame, and a blower is fixedly installed on the top of the flow guide cover.

[0006] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, it is characterized in that: a rain shield is fixedly installed on the top of the installation frame.

[0007] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, a connecting frame is fixedly installed between two adjacent installation frames.

[0008] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, a central shaft is fixedly installed inside the air deflector, a grounding cover is fixedly installed at the bottom of the central shaft, openings are formed on the front and back of the grounding cover, and the inside of the grounding cover is filled with counterweight particles.

[0009] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, the air deflector is a hollow funnel-shaped structure, and the diameters of both ends of the air deflector in the vertical direction are larger than the diameter of the middle part; the lower half of the central shaft is a conical structure, and the upper half of the central shaft is a cylindrical structure; a gap is provided between the lower half of the air deflector and the lower half of the central shaft.

[0010] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, a plurality of connecting pieces are fixedly installed between the air deflector and the central shaft.

[0011] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, the support column is arranged in a regular hexagonal column shape, and two groups of threaded holes are formed on each side surface; a support pad is fixedly installed at the bottom of the support column.

[0012] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, protective beams are fixedly installed on both sides of the installation frame, and a plurality of installation holes are formed on the surface of the installation frame.

[0013] In the high heat dissipation performance support frame for large-scale installation of the aforementioned inverter, an air inlet is formed on the side surface of the blower, and an air outlet is formed at the bottom of the blower.

[0014] Compared with the prior art, a high heat dissipation performance support frame for large-scale installation of an inverter provided by the present invention has the following beneficial effects: 1. By adopting a triangular array installation structure composed of tripods, the present invention can simultaneously provide installation positions for three groups of inverters, and the distances reserved between the inverters are the same. After installing the inverters, the air flow blown by one blower can be used to dissipate heat from the three groups of inverters at the same time, so as to save the installation cost and power consumption cost; the air flow blows obliquely downward through the gap between the air deflector and the central shaft, driving the air flow around the inverter, so as to dissipate heat from the inverter. Moreover, when the air flow blows out from the inside of the air deflector, it is directed downward of the inverter, avoiding the air flow blowing directly and accelerating the collision of impurities and particulate matters in the air against the inverter, and ensuring the integrity of the inverter while ensuring good heat dissipation of the inverter.

[0015] 2. The present invention installs a grounding cover at the bottom of the central axis. The grounding cover with a conical structure contacts the ground. By using the principle of point discharge, the charges inside the device are promoted to transfer to the ground. Thus, the probability that the support frame for installing the inverter is struck by lightning during thunderstorm weather can be reduced. And when struck by lightning, the current can be quickly transferred to the ground through the grounding cover, avoiding damage to the inverter caused by the current. By filling the grounding cover with weight particles, the overall center of gravity of the device can also be lowered, enabling the device to maintain good stability even in strong wind weather.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0018] Embodiment, a support frame with high heat dissipation performance for large-scale installation of an inverter, the structure refers to Figures 1-4 as shown, including a tripod 1, a cross beam 2 and a flow guide cover 3. A lightning protection rack 101 is welded to the top of the tripod 1. Three support columns 102 are fixedly installed at the bottom of the tripod 1. The tripod 1 can provide an installation position for the surrounding components and ensure the overall structural stability of the support frame. The lightning protection rack 101 can form a protection for the components at the bottom of the blower 4. On the one hand, it can prevent the blower 4 and the components at its bottom from being impacted. On the other hand, it can actively attract lightning strikes, and then transfer the current to the ground through the tripod 1 and the grounding cover 301, avoiding the current from being transferred to the ground through the inverter on the blower 4 and the mounting rack 202, thereby preventing the inverter from being damaged by lightning strikes. The support columns 102 can support the tripod 1 and can also provide an installation position for the cross beam 2; On one side of the support column 102, a cross beam 2 is installed by bolts. An installation frame 202 is installed on the outside of the cross beam 2, and a connecting frame 203 is fixedly installed between two adjacent installation frames 202. The cross beam 2 can provide an installation position for the surrounding components and connect two adjacent support columns 102 to ensure the overall stability of the support frame; the installation frame 202 is of an L-shaped structure and can provide an installation position for the inverter; the connecting frame 203 can fixedly connect two adjacent installation frames 202, so that the structures of the three installation frames 202 are stable with each other; A rain shield 201 is fixedly installed on the top of the installation frame 202. The rain shield 201 can protect the top of the inverter, thereby preventing the inverter from being eroded by rain and sun for a long time and shortening its service life; A flow guide cover 3 is fixedly installed inside the tripod 1. The flow guide cover 3 can provide an installation position for the surrounding components and guide the air flow to flow inside, thereby driving the air around the inverter to flow quickly to facilitate air cooling and heat dissipation of the inverter; A blower 4 is fixedly installed on the top of the flow guide cover 3. The blower 4 is of the FX-3 type. After being powered on, the blower 4 can blow air into the inside of the flow guide cover 3, thereby driving the surrounding air to flow.

[0019] Furthermore, a central shaft 303 is fixedly installed inside the flow guide cover 3. A grounding cover 301 is fixedly installed at the bottom of the central shaft 303. Openings are provided on the front and back of the grounding cover 301, and the inside of the grounding cover 301 is filled with counterweight particles 302. The flow guide cover 3 is of a hollow funnel-shaped structure, and the diameters of both ends of the flow guide cover 3 in the vertical direction are larger than the diameter of the middle part. The lower half of the central shaft 303 is of a conical structure, and the upper half of the central shaft 303 is of a cylindrical structure. A gap of 5 to 10 centimeters is provided between the lower half of the flow guide cover 3 and the lower half of the central shaft 303, and several connecting pieces are fixedly installed between the inside of the flow guide cover 3 and the central shaft 303. The central shaft 303 can provide an installation position for the grounding cover 301 and support the inner wall of the flow guide cover 3 to ensure the structural stability of the flow guide cover 3. The grounding cover 301 can use the principle of point discharge to quickly guide the current inside the support frame to the ground for release. Thus, when the device is struck by lightning, the current can be quickly conducted to the ground to prevent the lightning from passing through the inverter and damaging the inverter. The counterweight particles 302 can increase the weight of the grounding cover 301, thereby reducing the overall center of gravity height of the device to improve the stability of the device.

[0020] Furthermore, the support column 102 is a regular hexagonal column. Two sets of threaded holes are provided on the side surfaces of the support column 102, and a support pad 103 is fixedly installed at the bottom of the support column 102. The support column 102 can support the tripod 1 and can be connected to the cross beam 2 through bolts, facilitating the installation of the cross beam 2. By connecting to threaded holes at different heights, the installation height of the cross beam 2 can also be adjusted. The support pad 103 can be fixedly connected to the ground through bolts to ensure the installation stability of the support column 102.

[0021] Furthermore, protective beams are fixedly installed on both sides of the mounting frame 202, and a number of mounting holes are provided on the surface of the mounting frame 202. The protective beams can limit the inverter installed on the top of the mounting frame 202 in the horizontal direction to ensure the installation stability of the inverter.

[0022] Furthermore, four air inlets are provided on the side surface of the blower 4, and an air outlet is provided at the bottom of the blower 4. The blower 4 can suck air from the side and then blow the air vertically downward into the inside of the flow guide cover 3. Then, the air flow is guided by the flow guide cover 3, enabling the air flow to drive the air around the inverter and promoting the heat dissipation of the inverter.

[0023] Working principle: After the above-mentioned support frame is installed and checked to be correct, the inverter is supported by the mounting frame 202 and fixed to the mounting frame 202 through bolts. The blower 4 is powered on to rotate and blow air into the inside of the flow guide cover 3. The air is discharged obliquely downward after being guided by the flow guide cover 3 and the central shaft 303. The air flows at a high speed inside the mounting frame 202, driving the air inside and at the bottom of the mounting frame 202 to flow quickly, thereby achieving heat dissipation for the inverter. When being struck by lightning during a thunderstorm, the current is attracted by the lightning protection frame 101 and enters the device. The lightning is guided by the tripod and transmitted to the flow guide cover 3. Then, the current is transmitted to the grounding cover 301 through the central shaft 303 and released to the ground, avoiding the inverter during the current transmission process and ensuring the stability and safety of the inverter.
