A quality detection device for a photovoltaic module

Abstract

This utility model belongs to the field of photovoltaic module equipment technology and discloses a quality inspection device for photovoltaic modules. It includes a desktop with a connecting plate fixedly installed at the rear. A long groove is formed in the middle of the connecting plate, and a limiting block is movably connected to the top of the groove. The left end of the limiting block passes through the groove and extends to the outside of the left end of the groove, where a circular block is fixedly connected. This utility model, by setting up a circular block, a first motor, a rotating shaft, and a hollow block, allows the operator to start the first motor, causing the rotating shaft and hollow block to rotate. This causes the inner surface of the hollow block to press and push the outer surface of the circular block, which in turn causes the circular block to drive the limiting block, the moving block, and the mounting box to move downwards as a whole. This allows the operator to simulate impact on the photovoltaic modules from different heights, providing convenience for the operator.

Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module equipment technology, specifically a quality testing device for photovoltaic modules. Background Technology

[0002] Photovoltaic modules, also known as solar panels, are the core components of solar power generation systems. They are assembled from multiple photovoltaic cells using encapsulation materials and can directly convert sunlight into direct current electricity.

[0003] Currently, operators frequently use quality inspection devices when testing photovoltaic modules. However, while existing quality inspection devices have basic fixing functions, they lack height adjustment capabilities in their simulated stone impact test. Consequently, when operators need to simulate the impact of stones on the outer surface of photovoltaic modules at different heights, the device cannot meet their operational needs and therefore requires improvement. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a quality testing device for photovoltaic modules, which has the advantage of high adjustability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quality inspection device for photovoltaic modules, including a desktop, a connecting plate fixedly installed behind the desktop, an elongated groove in the middle of the connecting plate, a limiting block movably connected to the top of the elongated groove, the left end of the limiting block passing through the elongated groove and extending to the outside of the left end of the elongated groove and fixedly connected to a circular block, a first motor fixedly installed at the bottom of the left end of the connecting plate, a rotating shaft fixedly sleeved at the other end of the output shaft of the first motor, a hollow block fixedly connected to the right end of the rotating shaft, the interior of the hollow block movably sleeved with the outer surface of the circular block, and a moving block fixedly connected to the right side of the limiting block.

[0006] As a preferred embodiment of this invention, a movable block is movably installed inside the moving block, and a mounting box is fixedly connected to the right end of the movable block.

[0007] As a preferred embodiment of the present invention, a second motor is fixedly installed at the top of the mounting box, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the second motor. The bottom end of the rotating shaft passes through the mounting box and extends into the interior of the mounting box, and a fan blade is fixedly connected to its outer surface.

[0008] As a preferred embodiment of this utility model, a feed inlet is fixedly installed inside the right end of the mounting box, the other end of the feed inlet passes through the mounting box and extends to the outside of the mounting box, and a toothed plate is fixedly connected to the back of the mounting box.

[0009] As a preferred embodiment of this invention, a third motor is fixedly installed on the left side of the top of the moving block, and a round shaft is fixedly sleeved on the other end of the output shaft of the third motor.

[0010] In a preferred embodiment of this invention, a gear is fixedly sleeved on the outer surface of the circular shaft, and the outer surface of the gear meshes with the outer surface of the gear plate.

[0011] As a preferred embodiment of this utility model, pneumatic cylinders are fixedly installed on both the left and right sides of the top of the desktop, and a clamping plate is fixedly connected to the other end of the pneumatic cylinder.

[0012] As a preferred embodiment of this utility model, table legs are fixedly installed at the four corners of the bottom of the tabletop, and the number of table legs is four, with the four table legs having the same size.

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

[0014] 1. This utility model, by setting up a circular block, a first motor, a rotating shaft, and a hollow block, allows the operator to start the first motor, which will cause the rotating shaft and the hollow block to rotate. This causes the inner surface of the hollow block to press and push the outer surface of the circular block, which in turn causes the circular block to drive the limiting block, the moving block, and the mounting box to move downwards as a whole. This allows the operator to simulate the impact of stones on the photovoltaic module from different heights, bringing convenience to the operator.

[0015] 2. This utility model, by setting up a toothed plate, a third motor, a round shaft, and gears, allows the operator to start the third motor, which will cause the round shaft and gears to rotate, thereby causing the outer surface of the gear to mesh with the outer surface of the toothed plate. This, in turn, causes the toothed plate to drive the entire mounting box to move to the left. Due to the leftward movement of the mounting box, the operator can perform quality inspections on various positions on the top of the photovoltaic module during subsequent testing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, this utility model provides a quality inspection device for photovoltaic modules, including a desktop 1, a connecting plate 2 fixedly installed behind the desktop 1, an elongated groove 3 in the middle of the connecting plate 2, a limiting block 4 movably connected to the top of the elongated groove 3, the left end of the limiting block 4 passing through the elongated groove 3 and extending to the outside of the left end of the elongated groove 3 and fixedly connected to a round block 5, a first motor 6 fixedly installed at the bottom of the left end of the connecting plate 2, a rotating shaft 7 fixedly sleeved at the other end of the output shaft of the first motor 6, a hollow block 8 fixedly connected to the right end of the rotating shaft 7, the interior of the hollow block 8 movably sleeved with the outer surface of the round block 5, and a moving block 9 fixedly connected to the right side of the limiting block 4.

[0025] When the operator starts the first motor 6, the rotating shaft 7 and the hollow block 8 will rotate, causing the inner surface of the hollow block 8 to press and push the outer surface of the circular block 5. This causes the circular block 5 to drive the limiting block 4 and the moving block 9 to move downwards as a whole. This allows the operator to simulate the impact of stones of different heights on the surface of the photovoltaic module during subsequent stone impact testing.

[0026] The moving block 9 has a movable block 10 installed inside it, and the right end of the movable block 10 is fixedly connected to the mounting box 11.

[0027] Due to the design of the movable block 10, the movement of the mounting box 11 is effectively limited.

[0028] The top of the mounting box 11 is fixedly mounted with a second motor 12, and the other end of the output shaft of the second motor 12 is fixedly sleeved with a rotating shaft 13. The bottom end of the rotating shaft 13 passes through the mounting box 11 and extends into the interior of the mounting box 11, and a fan blade 14 is fixedly connected to its outer surface.

[0029] When the operator starts the second motor 12, the rotating shaft 13 will drive the fan blades 14 to rotate, thus simulating the situation where stones are accelerated by strong winds and hit the photovoltaic modules.

[0030] The mounting box 11 has a feed inlet 15 fixedly installed inside the right end, and the other end of the feed inlet 15 passes through the mounting box 11 and extends to the outside of the mounting box 11. The back of the mounting box 11 is fixedly connected to a toothed plate 16.

[0031] The design of the feed inlet 15 allows operators to put stones into the feed inlet 15.

[0032] Among them, a third motor 17 is fixedly installed on the left side of the top of the moving block 9, and a round shaft 18 is fixedly sleeved on the other end of the output shaft of the third motor 17.

[0033] When the operator starts the third motor 17, the circular shaft 18 will rotate.

[0034] Among them, a gear 19 is fixedly sleeved on the outer surface of the round shaft 18, and the outer surface of the gear 19 meshes with the outer surface of the gear plate 16.

[0035] When the round shaft 18 drives the gear 19 to rotate, the outer surface of the gear 19 will mesh with the outer surface of the toothed plate 16, thereby causing the toothed plate 16 to drive the entire mounting box 11 to move to the left.

[0036] Among them, pneumatic cylinders 20 are fixedly installed on both the left and right sides of the top of the desktop 1, and the other end of the pneumatic cylinder 20 is fixedly connected to a clamping plate 21.

[0037] When the operator operates the two pneumatic cylinders 20, the two clamping plates 21 will move in opposite directions.

[0038] Table legs 22 are fixedly installed at the four corners of the bottom of the tabletop 1. There are four table legs 22, and the four table legs 22 are the same size.

[0039] The design of the four table legs 22 provides excellent support for the tabletop 1.

[0040] Working principle and usage process of this utility model:

[0041] First, the operator places the photovoltaic module between two clamping plates 21. Then, the two pneumatic cylinders 20 are activated, causing the two clamping plates 21 to move in opposite directions, thus clamping and fixing the photovoltaic module. Next, the operator starts the second motor 12 and puts stones into the feed inlet 15. The operation of the second motor 12 causes the rotating shaft 13 and the fan blade 14 to rotate, and the stones will fall along the inside of the feed inlet 15 into the inside of the mounting box 11. Finally, they fall from the bottom of the mounting box 11 onto the top of the photovoltaic module, thus simulating the situation of stones falling onto the top of the photovoltaic module in a windy weather. Then, the operator starts the third motor 17, causing the round shaft 18 and the gear 19 to rotate, so that the outer surface of the gear 19 meshes with the outer surface of the toothed plate 16. This causes the toothed plate 16 to drive the mounting box 11 to move to the left, thus realizing the stone impact detection at various positions on the top of the photovoltaic module.

[0042] Finally, when the operator needs to perform stone impact testing at different heights, the operator starts the first motor 6, which will cause the rotating shaft 7 and the hollow block 8 to rotate. This causes the inner surface of the hollow block 8 to press and push the outer surface of the round block 5, which in turn causes the round block 5 to drive the limiting block 4, the moving block 9 and the mounting box 11 to move downwards as a whole. This allows the operator to perform stone impact testing on the outer surface of the photovoltaic module at different heights.
