Description

Technical Field

[0001] This utility model relates to the field of inverter cover technology, specifically a waterproof cover for inverters. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) power into alternating current (AC) power with fixed frequency and voltage or adjustable frequency and voltage. It consists of an inverter bridge, control logic, and filter circuits. To protect the internal structure and improve safety, inverters are usually equipped with a housing. To facilitate the installation of internal components, the front or rear side of the housing is designed with an open structure. After the components are installed, the opening of the housing is closed with a cover plate. Currently, there are two main methods for mounting the cover plate and the housing. One method is to fasten the cover plate and the housing with screws; the second method is to connect one side of the cover plate to the housing via a hinge. After the cover plate is fastened to the housing, the movable end of the cover plate is locked by a buckle. Since only screws are used for fastening, the first method requires a large number of screws, making the disassembly of the cover plate quite cumbersome. The hinge connection method requires an additional hinge mechanism, so the installation cost of the cover plate and housing is higher in the second method. Among them, the mounting structure of the inverter housing and cover plate and the inverter with patent application "CN201921093438.3" significantly reduces the number of threaded fasteners, making both the disassembly and installation of the cover plate simpler. Since no additional accessories are required, the production cost of the housing and cover plate mounting structure can also be reduced. However, the sealing effect of this cover plate structure is poor, allowing rainwater to easily enter the interior of the housing through the cover plate, damaging the internal components and affecting the normal operation of the inverter. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof cover for inverters, so as to solve the problem that the cover structure mentioned in the background art has poor sealing effect, which makes it easy for rainwater to enter the interior of the housing through the cover, causing damage to the internal components and thus affecting the normal use of the inverter.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof cover for an inverter, comprising a cover, a waterproof component, and a reinforcing component;

[0005] Wherein: the inner wall of the cover plate is provided with a receiving cavity, and decorative parts are connected to both sides of the top of the cover plate;

[0006] The waterproof component includes mounting grooves formed around the perimeter of the receiving cavity, an adhesive ring provided on the inner wall of the cover plate, an mounting strip connected to the bottom edge of the adhesive ring, the mounting strip being embedded in the mounting groove, an L-shaped connecting part installed on the top of the adhesive ring, and a waterproof ring connected to one side of the L-shaped connecting part.

[0007] The reinforcing component includes several transverse reinforcing ribs connected to the inner wall of the receiving cavity, and several longitudinal reinforcing ribs connected to the inner wall of the receiving cavity, wherein the transverse reinforcing ribs and the longitudinal reinforcing ribs are connected in a cross shape.

[0008] As a preferred embodiment of this utility model: the L-shaped connecting part and the waterproof ring form a flow channel, and the two ends of the surface of the cover plate are provided with drainage holes, which penetrate the receiving cavity and correspond to the flow channel.

[0009] As a preferred embodiment of this utility model: the inner wall of the receiving cavity is further provided with a roughening part between the cavity separated by the cross intersection of the transverse reinforcing ribs and the longitudinal reinforcing ribs.

[0010] As a preferred embodiment of this utility model: a number of heat dissipation strips are also fixedly connected to the top of the cover plate, and the heat dissipation strips are made of aluminum.

[0011] As a preferred embodiment of this utility model: a clearance groove is provided at both sides of the cover plate, and a mounting hole is provided through the interior of the clearance groove, and a mounting bolt is inserted and connected inside the mounting hole.

[0012] As a preferred embodiment of this utility model, both ends of the cover plate are provided with recessed handles.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) An installation groove is provided around the edge of the cavity. The rubber ring is embedded in the installation groove through the installation strip connected to the bottom edge. The top of the rubber ring is connected to an L-shaped connecting part. The L-shaped connecting part is cut to the inner wall of the cavity and extends to the inner wall edge of the cover plate. A waterproof ring is connected to one side of the L-shaped connecting part. The waterproof ring is set at the connection between the cover plate and the inverter housing to play a waterproof role. The connection between the L-shaped connecting part and the waterproof ring forms a flow channel. Drainage holes that penetrate the installation groove are provided on both sides of the surface of the cover plate. When rainwater seeps through the waterproof ring, it enters the flow channel and is discharged through the drainage holes, effectively preventing rainwater from entering the housing and playing a waterproof role.

[0015] (2) Through the provided reinforcing components, the inner wall of the cavity is connected with several transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs and longitudinal reinforcing ribs are connected in a cross shape, which improves the structural strength of the cover plate and can provide certain force support when the cover plate is subjected to external pressure.
