Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary tools for testing flat photovoltaic modules, and in particular relates to an auxiliary tool for testing flat photovoltaic modules. Background Art

[0002] Faced with the current severe climate change and energy crisis, my country is accelerating the process of energy revolution, continuously expanding the proportion of clean energy installed capacity, accelerating the construction progress of photovoltaic power generation projects, and achieving initial results in energy transformation. For photovoltaic modules installed flat, the light intensity must be stable and reach 700W / ㎡ or above to meet the test environment requirements. In winter, the solar radiation intensity is weak, and the radiation intensity on the plane where the photovoltaic modules are installed flat is difficult to meet the standard (or the time is very short). Therefore, the current common operation method is to shorten the working time of photovoltaic module power testing during the day in winter and manually remove and adjust the tilt angle. However, there are the following defects: (1) Testing is only carried out at noon when the sunlight is the strongest, which greatly reduces the efficiency of testing work. There is a serious phenomenon of idle work on site. When the radiation intensity is insufficient, the photovoltaic modules are removed and the modules are manually fixed at a tilt angle (reaching 700W / ㎡ or above) before on-site testing is carried out. After the removal of a single module, the fixed tilt angle can be completed by temporarily finding a support, but for grouped photovoltaic strings (multiple photovoltaic modules), the angles are required to be completely consistent, which is difficult to achieve, time-consuming and labor-intensive, and makes the test efficiency low. For this reason, we propose an auxiliary tool for testing flat photovoltaic modules. Summary of the invention

[0003] The purpose of the present invention is to provide an auxiliary tool for testing flat-laid photovoltaic modules to solve the problem of low testing efficiency caused by short testing time and time-consuming and labor-intensive testing of flat-laid photovoltaic modules in winter as mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an auxiliary tool for testing flat-laid photovoltaic modules, comprising a frame, two second hinges are fixed to the bottom of one end of the frame, and each second hinge is connected to a leg, and two sliding assemblies are symmetrically fixed to the bottom of the other end of the frame, a first hinge is installed on the sliding assembly, a lifting assembly is connected to the first hinge, a rotating assembly is connected to the bottom of the lifting assembly, a bottom plate is fixed to the bottom of the rotating assembly, a motor is fixed to the bottom plate, a main gear is fixed to the output end of the motor, a sub-gear is mounted on the outer wall of the lifting assembly, and the sub-gear and the main gear are connected by meshing.

[0005] Preferably, the sliding assembly consists of a slide rail and a slider, the slide rail is fixed on the bottom surface of the carriage, and the slider is connected to the slide rail by sliding.

[0006] Preferably, the cross section of the slide rail is a rectangular structure, and the longitudinal section of the slide rail is a T-shaped structure.

[0007] Preferably, the lifting assembly consists of a stud and a screw barrel, and the stud and the screw barrel are connected by threads.

[0008] Preferably, the rotating assembly consists of a rotating column and a rotating sleeve, and the rotating sleeve is installed on the outer wall of the rotating column by sleeve arrangement.

[0009] Preferably, the cross-sections of the rotating column and the rotating sleeve are both circular structures, and the longitudinal section of the rotating column is a convex structure.

[0010] Preferably, a spherical groove is formed on the bottom surface of the rotating column, and a ball is embedded in the spherical groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) Through the designed laying frame, first hinge, second hinge, sliding assembly, lifting assembly, rotating assembly, motor, main gear, sub-gear and legs, the legs and bottom plate at the bottom of the laying frame are fixed at the paving position of the photovoltaic modules, and then the photovoltaic modules in groups are installed on the laying frame together. When testing the light intensity of the photovoltaic modules laid flat in winter, the motor is started to rotate, and the main gear and sub-gear on the motor are meshed and driven to drive the screw barrel of the lifting assembly to rotate, and the screw barrel and the stud are screwed to lift one end of the laying frame. At the same time, the slider on the sliding assembly slides on the slide rail to achieve displacement, thereby ensuring that the photovoltaic modules equipped with the support column rotate from the paving state with the second hinge as the center of the circle, ensuring that the photovoltaic modules in the same group are stably fixed at the same inclination angle, and realizing that the photovoltaic module test can be carried out normally for more than 24 hours every day on sunny days in winter, which greatly improves the work efficiency. Through the designed ball bearings, the ball bearings play a lubricating role, reducing the wear and friction resistance between the rotating column and the bottom plate when rotating.

While lifting, the slider 17 on the sliding component 3 slides on the slide rail 16 to achieve displacement, thereby ensuring that the photovoltaic component equipped with the support column rotates from the flat state with the second hinge 13 as the center of the circle, ensuring that the photovoltaic components of the same group are stably fixed at the same inclination angle, and realizing that the photovoltaic component testing work can be carried out normally for more than 6 hours a day on sunny days in winter, which greatly improves the work efficiency. The moving component 3 is composed of a slide rail 16 and a slider 17. The slide rail 16 is fixed on the bottom surface of the paving frame 1.
