Description

Technical Field

[0001] This utility model relates to the field of power testing instrument technology, specifically a power testing instrument for double-glass modules in photovoltaic power plants. Background Technology

[0002] Double-glass photovoltaic (PV) modules refer to PV modules composed of two tempered glass panes, EVA film, and silicon solar cells laminated at high temperatures using a laminator. The cells are connected in series and parallel by wires to the lead ends, forming a complete PV module. Power testing instruments play a crucial role in the application of double-glass PV modules. They not only evaluate module performance and ensure product quality but also perform fault diagnosis and location, promoting technological innovation and improving economic efficiency. A power testing instrument is an electronic measuring instrument used to measure and analyze electrical power. Its main function is to measure the source impedance and load impedance of the device under test (DUT) to determine its maximum gain. However, current power testing instruments still have the following shortcomings:

[0003] For example, patent document CN219611726U discloses a portable photovoltaic module power detection device. During use, this portable photovoltaic module power detection device uses a solar simulation lamp that generates a large amount of light and heat energy. The heat is transferred through the detection board to the junction box and power detector. Excessive temperature can damage electronic components and shorten the device's lifespan. However, it can only detect the front of the photovoltaic module, requiring the back to be covered with a black cloth during testing, resulting in low testing efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a power testing instrument for double-glass modules in photovoltaic power plants. Utility Model Content

[0005] The purpose of this invention is to provide a power testing instrument for double-glass modules in photovoltaic power plants to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power testing instrument for double-glass modules in a photovoltaic power station, comprising a power tester and a movable component. The power tester is an integrated structure, and a protective shell is snapped onto the outside of the power tester. The movable component is disposed outside the protective shell and includes a limiting frame, a limiting groove, a return spring, a connecting rod, a limiting plate, a fixing column, a fixing plate, and a limiting disc. The limiting frame is disposed outside the protective shell, and a limiting groove is formed on the inner side of the right end of the limiting frame. Two sets of limiting grooves are symmetrically arranged, and a return spring is disposed on the left end inside the limiting groove. A connecting rod is installed on the right end of the return spring, and the connecting rod is slidably connected to the inner side of the limiting groove.

[0007] Furthermore, a limiting plate is installed on the right side of the connecting slide rod, and the limiting plate and the connecting slide rod are an integrated structure.

[0008] Furthermore, a fixing post is installed on the left surface of the limiting frame, and a fixing plate is rotatably connected to the outside of the fixing post.

[0009] Furthermore, a limiting disk is rotatably connected inside the fixing plate, and the right surface of the limiting disk is connected to the left surface of the fixing column.

[0010] Furthermore, the fixing plate is an integrated plastic structure, and the surface of the fixing plate is provided with mounting components for installation.

[0011] Furthermore, the mounting assembly includes a mounting frame, an anti-slip pad, and a threaded movable rod, with the mounting frame disposed on the left surface of the fixing plate.

[0012] Furthermore, the inner surface of the mounting frame is provided with an anti-slip pad, and the upper and lower sides of the mounting frame are threaded with movable rods.

[0013] Furthermore, the mounting assembly also includes a mounting plate and an auxiliary handle, with the mounting plate installed at the inner end of the threaded movable rod and the auxiliary handle provided at the outer end of the threaded movable rod.

[0014] This utility model provides a power testing instrument for double-glass modules in photovoltaic power plants, which has the following beneficial effects:

[0015] 1. This utility model incorporates a movable component, including a limiting frame, a limiting groove, a return spring, a connecting rod, a limiting plate, a fixing post, a fixing plate, and a limiting disc. In use, pulling the fixing plate outward causes the connecting rod to slide outward along the inner side of the limiting groove, which in turn causes the return spring to extend outward, locking the protective shell into the inner side of the limiting frame. Releasing the fixing plate causes the return spring to lose its force and, due to its elasticity, rebound and contract, causing the connecting rod to slide inward and reset, further resetting the fixing plate. The power tester is fixed by the fixing plate and the limiting frame. During use, the power tester can be rotated back and forth by the rotational connection between the fixing post and the inner side of the limiting plate. The limiting disc limits the fixing post, enabling the device to quickly fix the power tester. Furthermore, it can be angled and rotated back and forth as needed, allowing for monitoring of the front and back irradiance of the double-sided component, thus improving testing efficiency.

[0016] 2. This utility model features an installation assembly, which includes an installation frame, an anti-slip pad, and a threaded movable rod. The assembly also includes an installation plate and an auxiliary handle. In use, the installation frame is snapped onto the side of the photovoltaic module. By rotating the threaded movable rod through the auxiliary handle, the rod moves inward along the upper and lower surfaces of the installation frame, thereby moving the installation plate inward and securing the connection between the installation frame and the photovoltaic module. The anti-slip pad effectively prevents the installation frame from sliding and loosening, allowing the device to be quickly and stably installed on the photovoltaic module.

Detailed Implementation

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 3As shown, a power testing instrument for double-glass modules in a photovoltaic power station includes a power tester 1 and a movable component 3. The power tester 1 is an integrated structure, and a protective shell 2 is snapped onto the outside of the power tester 1. The movable component 3 is located outside the protective shell 2 and includes a limiting frame 301, a limiting groove 302, a return spring 303, a connecting rod 304, a limiting plate 305, a fixing column 306, a fixing plate 307, and a limiting disc 308. The limiting frame 301 is located outside the protective shell 2, and a limiting groove 302 is provided on the inner side of the right end of the limiting frame 301. Two sets of limiting grooves 302 are symmetrically arranged, and a return spring 303 is provided on the left end of the limiting groove 302. A connecting rod 304 is installed on the right end of the return spring 303, and the connecting rod 304 is slidably connected to the inner side of the limiting groove 302.

[0023] The specific operation is as follows: When in use, insert the device into the protective shell 2, pull the fixing plate 307 outward, so that the fixing plate 307 drives the connecting slide rod 304 to slide outward along the inner side of the limiting slide groove 302, thereby driving the return spring 303 to extend outward, insert the protective shell 2 into the inner side of the limiting frame 301, and release the fixing plate 307. At this time, the force on the return spring 303 disappears. Due to the elasticity of the return spring 303, the return spring 303 rebounds and contracts, thereby driving the connecting slide rod 304 to slide inward and reset, further driving the fixing plate 307 to reset. The power tester 1 is fixed by the fixing plate 307 and the limiting frame 301. During use, the power tester 1 can be flipped back and forth by the rotational connection between the fixing post 306 and the inner side of the limiting plate 305. The fixing post 306 is limited by the limiting plate 308.

[0024] Please refer to Figure 3 A limiting plate 305 is installed on the right side of the connecting slide rod 304, and the limiting plate 305 and the connecting slide rod 304 are an integral structure. A fixing post 306 is installed on the left surface of the limiting frame 301, and a fixing plate 307 is rotatably connected to the outside of the fixing post 306. A limiting disk 308 is rotatably connected inside the fixing plate 307, and the right surface of the limiting disk 308 is connected to the left surface of the fixing post 306. The fixing plate 307 is an integral plastic structure, and the surface of the fixing plate 307 is provided with mounting components 4 for installation. The mounting assembly 4 includes a mounting frame 401, an anti-slip pad 402, and a threaded movable rod 403. The mounting frame 401 is located on the left surface of the fixing plate 307. The anti-slip pad 402 is provided on the inner surface of the mounting frame 401. The threaded movable rod 403 is threadedly connected to the upper and lower sides of the mounting frame 401. The mounting assembly 4 also includes a mounting plate 404 and an auxiliary handle 405. The mounting plate 404 is installed on the inner end of the threaded movable rod 403, and the auxiliary handle 405 is provided on the outer end of the threaded movable rod 403.

[0025] The specific operation is as follows: When in use, the mounting frame 401 is snapped onto the side of the photovoltaic module. The threaded movable rod 403 is rotated by the auxiliary handle 405, so that the threaded movable rod 403 moves inward along the upper and lower surfaces of the mounting frame 401, thereby driving the mounting plate 404 to move inward, and tightening the connection between the mounting frame 401 and the photovoltaic module. The anti-slip soft pad 402 can play an effective anti-slip role and prevent the mounting frame 401 from sliding and loosening.

[0026] In summary, as Figures 1 to 3 As shown, the power testing instrument for the double-glass modules of this photovoltaic power station is used as follows: First, the fixed plate 307 is pulled outward from the protective housing 2, causing it to slide outward along the inner side of the limiting groove 302, which in turn causes the return spring 303 to extend outward. The protective housing 2 is then inserted into the inner side of the limiting frame 301. The fixed plate 307 is then released, and the return spring 303, now free of force, rebounds due to its elasticity, causing the connecting rod 304 to slide inward and reset, further resetting the fixed plate 307. The power is measured by the interaction between the fixed plate 307 and the limiting frame 301. The power tester 1 is fixed in place. During use, the power tester 1 can be rotated back and forth by the rotational connection between the fixed column 306 and the inner side of the limiting plate 305. The fixed column 306 is limited by the limiting plate 308. Then, the mounting frame 401 is snapped onto the side of the photovoltaic module. The threaded movable rod 403 is rotated by the auxiliary handle 405, so that the threaded movable rod 403 moves inward along the upper and lower surfaces of the mounting frame 401, thereby driving the mounting plate 404 to move inward, and tightening the connection between the mounting frame 401 and the photovoltaic module. The anti-slip soft pad 402 can play an effective anti-slip role and prevent the mounting frame 401 from sliding and loosening.
