Description

TECHNICAL FIELD

[0001] The utility model relates to the field of impact test equipment, and specifically relates to a solar film impact test device. BACKGROUND

[0002] The photovoltaic solar film is usually a photovoltaic film made of polymer material, which usually protects, prevents dust, prevents water, insulates heat and increases solar light absorption for solar cell modules, ensures that the solar panel can work normally and prolongs the service life under various harsh environments, and at the same time increases the absorption efficiency of solar cell modules to sunlight and improves the performance of solar cell modules.

[0003] The existing solar film impact test device usually fixes the solar film and the photovoltaic glass or backboard glass pressed into a module at the bottom of the test frame, and the impact ball is placed vertically through the hole slot at the top of the test frame, so as to impact the solar film to detect the protection ability of the solar film to the solar cell module.

[0004] However, the size of the test frame and the impact ball of the existing solar film impact test device is usually fixed, and the anti-impact ability of the solar film under different impact forces cannot be flexibly tested, therefore, a solar film impact test device is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] In order to make up for the deficiency of the prior art, in view of the problems existing in the prior art, the utility model provides a solar film impact test device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a solar film impact resistance testing device, comprising: a base plate, with third support plates fixed on both sides of the top rear end of the base plate, two second sliding grooves extending through each of the two third support plates on opposite sides, clamping blocks slidably disposed in each of the four second sliding grooves, and bolts threaded into one side of each of the four clamping blocks, a second support plate fixed on one side of the top of the base plate, a first support plate fixed on the other side of the top of the base plate, a first connecting rod fixed between the first support plate and the second support plate, a sleeve shaft sleeved in the middle of the first connecting rod, a second connecting rod fixed on the lower end shaft of the sleeve shaft, an impact ball fixed at the bottom of the second connecting rod, and an impact ball fixed on the upper end shaft of the impact ball. A water inlet plug is embedded on one side, and a drain plug is embedded in the bottom shaft of the impact ball. A third connecting rod is fixed on the shaft of the second connecting rod near the first support plate. A roller is sleeved on one side of the third connecting rod. An arc groove is formed through the first support plate, and the roller is slidably disposed in the arc groove. First sliding grooves are formed on both sides of the lower end of the first support plate, and a connecting plate is slidably disposed in the first sliding groove. Limiting plates are evenly fixed on the top of the connecting plate. The solar film is fixed to the third support plate with bolts. Pulling the connecting plate causes the limiting plate to slide out of the arc groove. At the same time, pulling the third connecting rod causes the roller to slide in the arc groove. The height of the roller is limited by the limiting plate, which flexibly tests the impact resistance of the solar film under different impact intensities.

[0007] Preferably, the height of the five limiting plates decreases sharply in proportion to the arc groove, the arc groove is in a downward throwing shape, and the limiting plates decrease sharply in proportion, so that the top of the limiting plate can always slide out of the arc groove.

[0008] Preferably, each of the four clamping blocks has a nut threaded onto its rear end, which allows for flexible adjustment of the height of the clamping blocks and facilitates clamping of solar films of different test sizes.

[0009] Preferably, springs are fixed on both sides of the top of the connecting plate, so that the connecting plate can rebound, which facilitates the limiting plate to limit the position.

[0010] Preferably, the limiting plate is slidably disposed within the first support plate, and the top of the limiting plate is slidably disposed within the arc groove. By the top of the limiting plate being slidably disposed within the arc groove, a barrier plate shape is formed within the arc groove, which facilitates the limiting of the roller.

[0011] Preferably, the first support plate has a scale at the lower end of the arc groove, which facilitates quick adjustment of the impact force.

[0012] The advantages of this utility model are as follows: the solar film is fixed to the third support plate with bolts, the connecting plate is pulled to make the limiting plate slide out of the arc groove, and at the same time the third connecting rod is pulled to drive the roller to slide in the arc groove to adjust the height of the roller and the impact ball. The roller height is adjusted according to the scale to adjust the impact force. The connecting plate is pulled again to make the limiting plate slide out of the arc groove. The impact ball swings down due to gravity to conduct an impact test on the solar film. The limiting plate restricts the position of the roller, and the impact resistance of the solar film under different impact forces can be flexibly tested. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-5 As shown, a solar film impact resistance testing device includes: a base plate 1, with third support plates 15 fixed on both sides of the top rear end of the base plate 1; two second sliding grooves 16 are opened through each of the two third support plates 15 on opposite sides; clamping blocks 17 are slidably arranged in each of the four second sliding grooves 16; bolts 18 are threaded into one side of each of the four clamping blocks 17; a second support plate 4 is fixed on one side of the top of the base plate 1; a first support plate 2 is fixed on the other side of the top of the base plate 1; a first connecting rod 5 is fixed between the first support plate 2 and the second support plate 4; a sleeve shaft 6 is sleeved in the middle of the first connecting rod 5; and a shaft body is fixed at the lower end of the sleeve shaft 6. There is a second connecting rod 7, and an impact ball 8 is fixed at the bottom of the second connecting rod 7. A water inlet plug 20 is embedded in one side of the upper shaft of the impact ball 8, and a drain plug 21 is embedded in the lower shaft of the impact ball 8. A third connecting rod 9 is fixed on the shaft of the second connecting rod 7 near the first support plate 2. A roller 3 is sleeved on one side of the third connecting rod 9. An arc groove 10 is opened through the first support plate 2. The roller 3 is slidably disposed in the arc groove 10. A first sliding groove 11 is opened on both sides of the lower end of the first support plate 2. A connecting plate 12 is slidably disposed in the first sliding groove 11. A limit plate 13 is evenly fixed on the top of the connecting plate 12.

[0023] During the impact resistance test of the solar film, the solar film is fixed to the two third support plates 15 by screwing the nut 19 to the threaded post at the rear end of the clamping block 17 and adjusting the height of the clamping block 17. The connecting plate 12 is pulled so that the proportionally reduced limiting plate 13 no longer penetrates the arc groove 10. The third connecting rod 9 is pulled to raise the roller 3 and the impact ball 8 to one side. The connecting plate 12 is then quickly released by observing the scale. Under the action of the spring 14, the limiting plate 13 rebounds to limit the position of the roller 3, thus fixing it. When the height of the impact ball 8 is adjusted, the connecting plate 12 is pulled again, causing the limiting plate 13 to disengage from the arc groove 10. The impact ball 8 then swings downwards due to gravity, impacting the solar film. The weight of the impact ball 8 can be flexibly adjusted through the inlet plug 20 and the drain plug 21 to enhance the impact force. The limiting space formed by the arc groove 10 and the limiting plate 13 restricts the roller 3, thereby limiting the impact ball 8 at different heights and with different impact forces, making it convenient to flexibly test the impact resistance of the solar film under different impact forces.

[0024] The height of the five limiting plates 13 decreases sharply in proportion to the arc groove 10. The arc groove 10 has a downward-projecting shape with a certain curvature. The proportional decrease in the height of the limiting plates 13 ensures that the top part of the limiting plates 13 can always slide out of the arc groove 10, thereby limiting the roller 3 at different heights. Nuts 19 are threaded onto the rear ends of the four clamping blocks 17, and are screwed to the threaded post at the rear end of the clamping blocks 17 via the nuts 19, facilitating flexible adjustment of the height of the clamping blocks 17 and facilitating the clamping of solar films of different test sizes. Springs 14 are fixed on both sides of the top of the connecting plate 12. The spring 14 fixes the connecting plate 12 on one hand and allows the connecting plate 12 to rebound on the other hand, which facilitates the back-and-forth sliding of the limiting plate 13. The limiting plate 13 is slidably disposed in the first support plate 2, and the top of the limiting plate 13 is slidably disposed in the arc groove 10. By the top of the limiting plate 13 being slidably disposed in the arc groove 10, a barrier plate is formed in the arc groove 10, which facilitates the restriction of the height of the roller 3 to limit the swing height of the impact ball 8. The first support plate 2 is provided with a scale at the lower end of the arc groove 10, which facilitates quick observation and adjustment of the impact force.

[0025] Working principle: When conducting an impact resistance test on the solar film, the solar film is fixed to the two third support plates 15 by screwing the nut 19 to the threaded post at the rear end of the clamping block 17, adjusting the height of the clamping block 17, and pulling the connecting plate 12 so that the proportionally reduced limiting plate 13 no longer penetrates the arc groove 10. Pulling the third connecting rod 9 causes the roller 3 and impact ball 8 to rise to one side. Quickly observe the scale and then release the connecting plate 12. Under the action of the spring 14, the limiting plate 13 rebounds and restricts the position of the roller 3. With the height of the impact ball 8 fixed, the connecting plate 12 is pulled again, causing the limiting plate 13 to disengage from the arc groove 10 again. The impact ball 8 swings downward due to gravity, impacting the solar film. The weight of the impact ball 8 can be flexibly adjusted through the water inlet plug 20 and the drain plug 21 to enhance the impact force. The limiting space formed by the arc groove 10 and the limiting plate 13 restricts the roller 3, thereby limiting the impact ball 8 at different heights and with different impact forces, making it convenient to flexibly test the impact resistance of the solar film under different impact forces.
