Description

Technical Field

[0001] The utility model relates to an inverter shell, in particular to a photovoltaic inverter shell, and belongs to the technical field of photovoltaic inverters. Background Art

[0002] Photovoltaic inverters are inverters that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverters are one of the important system balancers in photovoltaic array systems and can be used with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding protection.

[0003] However, when operators inspect and repair the internal components of the photovoltaic inverter, they need to remove the inverter casing from the equipment. The existing inverter casing is generally fixed to the equipment by multiple bolts. During installation and removal, tools are needed to remove the casing. In addition, the bolts are small in size, which makes them inconvenient to store and easy to lose during the installation process, which is not conducive to improving the efficiency of casing disassembly and assembly. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic inverter housing in order to solve the above-mentioned problem. The pull block is lifted and rotated so that the abutment plate drives the card block to slide and separate from the protective mechanism, thereby facilitating the operator to quickly disassemble and assemble the inverter housing, thereby helping to reduce the cumbersome steps of fixing the housing with bolts.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: a photovoltaic inverter housing, including an inverter body, a protective mechanism, a limiting mechanism and a connecting mechanism are installed on the inverter body, the connecting mechanism is cooperated with a mounting mechanism, the limiting mechanism and the protective mechanism are cooperated and connected, the limiting mechanism includes a connecting block, two groups of connecting blocks are symmetrically fixedly installed on the inverter body, a connecting rod is slidably connected to the connecting block, a compression spring is sleeved on the connecting rod, and the connecting rod is fixedly connected to a back plate, a pulling block and a clamping block are fixedly connected to the back plate, and the clamping block is cooperated with the protective mechanism.

[0006] Preferably, the connecting rod is connected to the connecting block through a compression spring, and the abutment plate abuts against the connecting block.

[0007] Preferably, the protection mechanism comprises a cover plate, the abutment plate abuts against the cover plate, and the cover plate is snap-connected with the inverter body.

[0008] Preferably, the protection mechanism further comprises limiting grooves, and two groups of limiting grooves are symmetrically arranged on the cover plate, and the limiting grooves are provided with abutment plates for sliding cooperation.

[0009] Preferably, the protection mechanism further comprises a card slot, and two groups of card slots are symmetrically arranged on the cover plate, and a card block is engaged with the card slot.

[0010] Preferably, the connection mechanism comprises a fixing plate, the fixing plate is fixedly mounted on the inverter body, and a slot is provided on the fixing plate.

[0011] Preferably, the installation mechanism comprises an inserting plate, the slot portion is engaged with an inserting plate, the top end of the inserting plate is arranged in an inclined surface, two groups of the inserting plates are fixedly connected to the bottom plate, and the bottom plate is in contact with the fixed plate.

[0012] Preferably, the mounting mechanism further comprises a gasket, the plug plate is bonded with the gasket, and the gasket is in contact with the fixing plate.

[0014] Preferably, the mounting mechanism further comprises a fixing frame, two sets of fixing frames are symmetrically fixedly connected to the bottom plate, and the bottom plate is provided with a heat dissipation groove.

[0015] The beneficial effect of the utility model is that when it is necessary to inspect the inside of the inverter body, the operator can use the hand to pull the pulling block, which is fixedly connected to the back plate. When the pulling block drives the back plate to slide, a connecting rod is fixed on the back plate. When the connecting rod slides with the back plate, the compression spring sleeved on the connecting rod is squeezed. When the compression spring is in a compressed state, the card block fixed on the back plate can slide out of the protective mechanism. Then the pulling block is rotated, and the back plate drives the card block to rotate with the rotation of the pulling block, thereby rotating the back plate and the card block to the side away from the protective mechanism. This makes it convenient for the operator to disassemble and assemble the inverter housing while also helping to reduce the tedious steps of fixing the inverter housing with bolts.
