[0002] Photovoltaic power generation is a technology that converts solar energy into electrical energy using the photovoltaic effect, also known as solar power generation. It is one of the most common and mature new energy power generation technologies at present. Photovoltaic power generation converts light energy into direct current electrical energy and then converts it into alternating current electrical energy through an inverter for power supply or injection into the power grid.

[0003] In the prior art, the installation methods of the inverter and the step-up transformer both adopt bolt connection. And because the inverter and the step-up transformer are usually large in volume, external lifting equipment is needed to lift the inverter and the step-up transformer into the inner part of the shell respectively, and then they are connected by multiple groups of bolts respectively. This process requires manual entry into the inner part of the shell for bolt installation. Due to the limited space inside the shell, the installation speed of the inverter and the step-up transformer is slow. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a photovoltaic inverter step-up integrated machine is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a photovoltaic inverter step-up integrated machine, including a shell. A motor slot is opened at the bottom of the inner wall of the shell. A motor is installed at the bottom of the inner wall of the motor slot. Both output ends of the motor are fixedly connected with screw rods. A moving block is threadedly connected to the outer wall of the screw rod. A linkage column is fixedly connected to the top of the moving block. An installation plate is arranged inside the shell. Pulley groups are movably connected to the outer walls on both sides of the installation plate, and the number of pulleys in each group is multiple. Sliding grooves are opened on both sides of the inner wall of the shell, and the pulleys are located inside the sliding grooves. Linkage grooves are opened at the bottom of the installation plate, and the number of the linkage grooves is two. The linkage columns are located inside the linkage grooves. An inverter is connected to the top of the installation plate by bolts, and a step-up transformer is connected to the top of the installation plate by bolts. A support plate is fixedly connected to the front outer wall of the shell.

[0006] As a further description of the above technical solution:

[0007] Heat dissipation grooves are opened on both outer walls of the shell, and the number of the heat dissipation grooves is multiple.

[0008] As a further description of the above technical solution:

[0009] Filter meshes are fixedly connected to the inner walls of the multiple heat dissipation grooves. Waterproof plates are fixedly connected to both outer walls of the shell, and the number of the waterproof plates is multiple.

[0010] As a further description of the above technical solution:

[0011] The positions of the multiple waterproof plates respectively correspond to the positions of the multiple heat dissipation grooves, and the multiple waterproof plates are respectively located at the edges of the multiple heat dissipation grooves.

[0012] As a further description of the above technical solution:

[0013] A cabinet door is movably connected to the front outer wall of the housing through a hinge, and the number of cabinet doors is two.

[0014] As a further description of the above technical solution:

[0015] Observation ports are respectively opened at the upper ends of the two cabinet doors, and fixed support feet are fixedly connected to the outer walls on both sides of the housing, and the number of fixed support feet is two respectively.

[0016] The utility model has the following beneficial effects:

[0017] 1. Before installing the inverter and the booster, the motor runs to drive the lead screws connected to both ends to rotate, so that the two moving blocks and the linkage columns connected to their tops move away from each other. While the two linkage columns move away from each other, they respectively move along the two linkage grooves opened at the bottom of the mounting plate, so that the mounting plate moves towards the outside of the housing. When the mounting plate moves outwards, the multiple pulleys movably connected to the outer walls on both sides thereof move along the sliding grooves, making the process of the mounting plate moving outwards more convenient. After the front end of the mounting plate extends out of the housing, there is a support plate as a support at the same time. The inverter and the booster are installed on the mounting plate through multiple groups of bolts. Subsequently, the motor runs in the reverse direction, and for the same principle, the mounting plate returns to the inside of the housing to be in place. The operator can install the inverter and the booster without entering the inside of the housing. The installation process is not restricted by space, and the installation efficiency is high and the speed is fast. In the prior art, the installation methods of the inverter and the booster both adopt bolt connection, and since the inverter and the booster are usually large in volume, the inverter and the booster need to be hoisted into the housing respectively by an external lifting device, and then connected through multiple groups of bolts. This process requires manual entry into the housing to install the bolts. Due to the limited space inside the housing, the installation speed of the inverter and the booster is slow. With this device, the operator can install the inverter and the booster without entering the inside of the housing. The installation process is not restricted by space, and the installation efficiency is high and the speed is fast;

[0018] 2. A plurality of heat dissipation grooves are respectively opened on both sides of the housing. The heat generated when the inverter and the booster work can be discharged through the plurality of heat dissipation grooves. Filters are respectively connected inside the plurality of heat dissipation grooves, which can prevent dust from entering the inside of the housing. At the same time, a plurality of waterproof plates are respectively connected to the outer walls on both sides of the housing, which can prevent water from entering the inside of the housing through the heat dissipation grooves.
