[0012] Beneficial effects
[0013] This utility model provides a smart inverter with a protective device. It offers the following advantages: The smart inverter with the protective device, through the cooperation of a protective unit, a protective shell, and a fixing strip, inserts the buckle at the bottom of the fixing strip into the interior of the fixing shell. Under the action of the protrusions on the outer wall of the buckle, it is fixed inside the fixing shell, thus securing the protective shell to the top of the mounting shell. This prevents rainwater from directly hitting the top of the mounting shell, thus avoiding damage to the internal electronic components of the inverter.

[0014] By using honeycomb panels, mounting frames, and limiting plates, the honeycomb panels block external wind and rain, preventing sand and rainwater from entering the inverter's interior. At the same time, the honeycomb panels can be replaced periodically to ensure effective protection. This solves the problem of insufficient protection in existing inverters, which leads to a reduced lifespan for the inverter. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In actual use, since inverters mostly operate outdoors, they are easily corroded by rain and sand, which can damage their internal electronic components and shorten their lifespan.
[0022] In view of this, the present invention provides an intelligent inverter with a protective device, which solves the problem that in actual use, since the inverter's working environment is mostly outdoors, it is easily affected by rain and sand erosion, which can damage the internal electronic components and shorten the inverter's service life.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0024] Example 1: By Figure 1-4 It is known that a smart inverter with a protective device includes a mounting shell 1, a fixing block 3 is fixedly connected to the lower part of the outer wall of the mounting shell 1, and a base plate 2 is fixedly connected to the outer wall of the fixing block 3 by bolts. The smart inverter with the protective device also includes a protective unit 4 and a protective structure 5. The protective unit 4 is installed on the top of the mounting shell 1; the protective structure 5 is installed on the outer wall of the mounting shell 1. The protective unit 4 protects the mounting shell 1, and the protective structure 5 protects the sides of the mounting shell 1.
[0025] In the specific implementation process, it is worth noting that the electronic components required for the inverter are installed inside the base plate 2 and the mounting shell 1. This technology is well known in the field of heat source technology, so it will not be described in detail here. Moreover, the protection unit 4 can protect the mounting shell 1 and prevent rainwater from dripping onto the outer wall of the mounting shell 1. Furthermore, the protection structure 5 will protect the inverter's heat dissipation device and prevent external particles and rainwater from entering the inverter through the heat dissipation device, thereby protecting the inverter.
[0026] Furthermore, the protective unit 4 includes a protective shell 41, a fixing strip 42, a buckle 43, and a fixing shell 44. The protective shell 41 is disposed above the mounting shell 1; the fixing strip 42 is fixedly connected to the bottom of the protective shell 41; the buckle 43 is fixedly connected to the bottom of the fixing strip 42; the fixing shell 44 is sleeved on the outer wall of the buckle 43, and its bottom is fixedly connected to the top of the mounting shell 1; wherein, through the cooperation of the buckle 43 and the fixing shell 44, the fixing strip 42 fixes the protective shell 41 to the top of the mounting shell 1.
[0027] In the specific implementation process, it is worth noting that there are two buckles 43, which are fixed on the bottom sides of the fixing strip 42 respectively. The buckles 43 themselves have a certain elasticity. When installing the protective shell 41, the buckles 43 at the bottom of the protective shell 41 are inserted into the inside of the fixing shell 44, and the protective shell 41 is fixed to the top of the mounting shell 1. This can protect the main body of the inverter. Moreover, the protective shell 41 is made of aluminum alloy with a thickness of 3-5mm and the surface is anodized, which makes it more resistant to corrosion from the external environment.
[0028] Furthermore, a slot 7 is provided on the top of the base plate 2, and a sealing strip 8 is fixedly connected to the bottom of the inner wall of the slot 7. The slot 7 is fitted onto the outer wall of the mounting shell 1, and the bottom is pressed against the top of the sealing strip 8. A sealing plate 6 is pressed against the top of the base plate 2, and the inner wall of the sealing plate 6 is fixedly connected to the bottom of the outer wall of the mounting shell 1.
[0029] In the specific implementation process, it is worth noting that the shape of the slot 7 matches the shape of the mounting shell 1. After the mounting shell 1 is inserted into the slot 7, it will press against the top of the sealing strip 8 inside the slot 7. Then, the fixing block 3 is fixed to the top of the base plate 2 by bolts, thereby increasing the pressure of the mounting shell 1 on the sealing strip 8. At the same time, the sealing strip 8 will seal the gap between the mounting shell 1 and the base plate 2 to prevent impurities from entering. Moreover, the sealing plate 6 will seal the gap between the slot 7 and the mounting shell 1, performing a secondary seal to ensure a better sealing effect.
[0030] Example 2: From Figure 1-4It is known that the protective structure 5 includes a honeycomb panel 51, a mounting frame 52, a limiting plate 53, a trapezoidal block 54, and a fixing structure 55. The honeycomb panel 51 is disposed on one side of the outer wall of the mounting shell 1; the mounting frame 52 is fixedly connected to the outer wall of the honeycomb panel 51; the limiting plate 53 is disposed above the mounting frame 52 and fixedly connected to the outer wall of the mounting shell 1; the trapezoidal block 54 is fixedly connected to the top of the mounting frame 52 and slidably engaged with the bottom of the limiting plate 53; the fixing structure 55 is installed on the outer wall of the mounting frame 52; wherein, through the cooperation of the mounting frame 52 and the limiting plate 53, the trapezoidal block 54 installs the honeycomb panel 51 at the bottom of the limiting plate 53, and the fixing structure 55 fixes the mounting frame 52.
[0031] In the specific implementation process, it is worth noting that the honeycomb panel 51 can be made of activated carbon. Utilizing its own pores, it can filter moisture and impurities, preventing impurities from entering the inverter. At the same time, the honeycomb panel 51 is installed on the outside of the inverter heat sink, thereby preventing impurities from entering the inverter through the heat sink. When installing the honeycomb panel 51, the trapezoidal block 54 at the top of the mounting frame 52 is inserted into the bottom of the limiting plate 53, and the mounting frame 52 and the honeycomb panel 51 are fixed to the outer wall of the mounting shell 1 with the help of the fixing structure 55.
[0032] Furthermore, the fixing structure 55 includes a locking block 551, a limiting rod 552, and a sliding groove 553. The locking block 551 is movably connected to the outer wall of the mounting shell 1, and the outer wall is in contact with the outer wall of the mounting frame 52. The limiting rod 552 is fixedly connected to the outer wall of the mounting frame 52 and inserted into the inner wall of the locking block 551. The sliding groove 553 is slidably engaged with the outer wall of the locking block 551 and is formed in the outer wall of the mounting shell 1. The locking block 551 fixes the mounting frame 52 through the cooperation of the sliding groove 553 and the limiting rod 552.
[0033] In the specific implementation process, it is worth noting that after the mounting frame 52 is attached to the outer wall of the mounting shell 1, the locking block 551 is slid down so that the locking block 551 is locked on the outer wall of the limiting rod 552. This can fix the mounting frame 52 between the mounting shell 1 stably and avoid instability during long-term use.
[0034] Furthermore, a copper foil layer 9 is attached to the inner wall of the mounting housing 1;
[0035] In the specific implementation process, it is worth noting that the copper foil layer 9 is equipped with shielded twisted pair wires, and one end is grounded. This can reduce signal interference and ensure that the inverter is not affected by external signals during use.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
