The inverter main body is installed at the front end of the mounting plate. The top and bottom ends of both sides of the mounting plate are fixedly connected with support rods. Heat dissipation frames are arranged on both sides of the mounting plate. A rain shelter is arranged at the top of the mounting plate. The bottom end of the rain shelter is fixedly connected with a support frame. A reserved slot is arranged inside the mounting plate. An electric push rod is installed inside the reserved slot. A humidity sensor is fixedly connected to the bottom end of the left side of the mounting plate. A mounting card slot is fixedly connected to the front end of the mounting plate. A mounting card block is fixedly connected to the rear end of the inverter main body. A limit slider is fixedly connected to the bottom end of the support frame.

[0007] Preferably, the output end of the electric push rod is fixedly connected to the bottom end of the limit slider, and the limit slider is embedded in the mounting plate and is slidably connected.

[0008] Preferably, the humidity sensor is electrically connected to the electric push rod, and four groups of bolts are arranged on the mounting plate.

[0009] Preferably, dust-proof mesh plates are installed on both sides of the heat dissipation frame, and heat dissipation fans are installed inside the heat dissipation frame.

[0015] (1) By providing a rain shelter, a support frame, a humidity sensor, a limiting slider, a reserved slot and an electric push rod, the rain shelter can protect the inverter body from rain. When the air humidity is low on a sunny day and the humidity sensor detects the humidity value of the sunny weather, the electric push rod pushes the rain shelter upward, and the rain shelter moves away from the top of the inverter body to improve its heat dissipation effect. When the air humidity is high on a rainy day and the humidity sensor detects a large humidity value, the electric push rod drives the rain shelter to move downward to be close to the top of the inverter body to achieve rain protection. This structure realizes the function of facilitating the enhancement of the rain protection effect;

[0016] (2) By providing a heat dissipation frame, a mounting sleeve, a support rod and a locking bolt, the heat dissipation frame can dissipate heat from both sides of the inverter body. The heat dissipation fan inside the heat dissipation frame can accelerate the air flow rate near the inverter body to take away heat. The heat dissipation frame does not contact the surface of the inverter body and does not affect its own heat dissipation. The heat dissipation frames distributed on both sides of the inverter body can also provide anti-collision protection for its two sides. This structure realizes the function of facilitating heat dissipation and protection;

[0017] (3) By providing a mounting plate, a limiting plate, a mounting slot, a positioning buckle and a positioning slot, before installing the inverter body, the mounting plate needs to be installed and fixed in a specified area first.

An electric push rod 17 is installed inside the reserved slot 16. A humidity sensor 9 is fixedly connected to the bottom end of the left side of the mounting plate 8. A mounting card slot 11 is fixedly connected to the front end of the mounting plate 8. A mounting card block 14 is fixedly connected to the rear end of the inverter main body 1. A limiting slider 15 is fixedly connected to the bottom end of the support frame 5;

[0025] The output end of the electric push rod 17 is fixedly connected to the bottom end of the limiting slider 15. The limiting slider 15 is embedded in the mounting plate 8 and is slidably connected. The humidity sensor 9 is electrically connected to the electric push rod 17. Four groups of bolts are arranged on the mounting plate 8;

[0026] Specifically, as Figure 1 and Figure 4As shown, on sunny days, the air humidity is relatively low. When the humidity sensor 9 detects the humidity value of sunny weather, the electric push rod 17 pushes the rainproof shed 4 upward, and the rainproof shed 4 moves away from the top of the inverter main body 1 to improve its heat dissipation effect. When the air humidity is high on rainy days and the humidity sensor 9 detects a large humidity value, the electric push rod 17 drives the rainproof shed 4 to move downward to be close to the top of the inverter main body 1 to achieve rain protection.

[0027] Embodiment 2: Dust-proof net plates are installed on both sides of the heat dissipation frame 2, a heat dissipation fan is installed inside the heat dissipation frame 2, mounting sleeves 3 are fixedly connected to the top end and the bottom end of the heat dissipation frame 2, a locking bolt 7 is arranged at the front end of the mounting sleeve 3, and the mounting sleeve 3 is sleeved outside the support rod 6;

[0028] Specifically, as Figure 1 and Figure 2 shown, the heat dissipation fan inside the heat dissipation frame 2 can accelerate the air flow rate near the inverter main body 1 to take away heat. The heat dissipation frame 2 does not contact the surface of the inverter main body 1 and does not affect its own heat dissipation. The heat dissipation frames 2 distributed on both sides of the inverter main body 1 can also provide anti-collision protection for its two sides.

[0029] Embodiment 3: The installation block 14 is in an "I" shape, the installation block 14 is embedded inside the installation slot 11, a limiting plate 10 is movably hinged to the left side of the top end of the installation slot 11, a positioning buckle 12 is movably hinged to the right side of the limiting plate 10, a positioning slot 13 is fixedly connected to the top end of the right side of the installation slot 11, the limiting plate 10 covers the top end of the installation slot 11, and the positioning buckle 12 is embedded inside the positioning slot 13;

[0030] Specifically, as Figure 1 and Figure 3 shown, during installation, the installation block 14 on the inverter main body 1 is inserted into the installation slot 11, then the limiting plate 10 is covered on the top of the installation slot 11, and the positioning buckle 12 on the limiting plate 10 is buckled inside the positioning slot 13 for limitation. When disassembling, only need to open the positioning buckle 12 and remove the inverter main body 1.

[0031] Working principle: When the utility model is in use, the device is first installed on the mounting plate 8.

On sunny days, the air humidity is relatively low. When the humidity sensor 9 detects the humidity value of sunny weather, the electric push rod 17 pushes the rainproof shed 4 upwards, and the rainproof shed 4 moves away from the top of the inverter main body 1 to improve its heat dissipation effect. On rainy days, the air humidity is relatively high. When the humidity sensor 9 detects a relatively high humidity value, the electric push rod 17 drives the rainproof shed 4 to move downwards and close to the top of the inverter main body 1 to achieve rain protection. The heat dissipation frame 2 can dissipate heat from both sides of the inverter main body 1. The heat dissipation fan inside the heat dissipation frame 2 can accelerate the air flow rate near the inverter main body 1 to take away heat. The heat dissipation frame 2 does not contact the surface of the inverter main body 1 and does not affect its own heat dissipation. The heat dissipation frames 2 distributed on both sides of the inverter main body 1 can also provide anti-collision protection for both sides. This structure realizes the function of facilitating heat dissipation and protection.
