Description

Technical Field

[0001] This utility model relates to the field of glass impact testing technology, specifically to an impact testing device for high-strength impact-resistant photovoltaic enamel glass. Background Technology

[0002] High-strength, impact-resistant photovoltaic glazed glass, as a key protective layer for photovoltaic modules, must simultaneously meet the requirements of light transmittance, weather resistance, and impact resistance. Its impact testing device is the core equipment for verifying product performance and ensuring the long-term stable operation of photovoltaic systems.

[0003] In existing impact testing devices, the impact ball is slightly deflected by the friction of the baffle at the moment of fall. If no subsequent intervention is taken, the final landing point of the impact ball will deviate significantly from the expected landing point during long-distance falls, thus affecting the test results. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an impact testing device for high-strength, impact-resistant photovoltaic coated glass, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution: This utility model relates to an impact testing device for high-strength, impact-resistant photovoltaic coated glass, comprising: An impact testing assembly includes a metal stage, a first hydraulic cylinder, a rectangular plate, baffles, and an impact ball. The bottom end of the first hydraulic cylinder is fixedly connected to the side of the metal stage, the top end of the first hydraulic cylinder is fixedly connected to the rectangular plate, the front end of the rectangular plate is movably connected to the baffle, and the impact ball is movably connected between the baffles. An anti-deviation assembly includes a cylindrical bending rod, a horn-shaped tube, and a ceramic guide sleeve. One end of the cylindrical bending rod is fixedly connected to the side of the first hydraulic cylinder, the other end of the cylindrical bending rod is fixedly connected to the ceramic guide sleeve, and the horn-shaped tube is fixedly connected to the top of the ceramic guide sleeve.

[0005] Furthermore, the horn tube has an overall structure that is wider at the top and narrower at the bottom.

[0006] Furthermore, the impact testing assembly also includes a semi-circular groove, an L-shaped rod, and a second hydraulic cylinder. The side of the baffle has a semi-circular groove, and an impact ball is movably connected between the semi-circular grooves. One end of the L-shaped rod is fixedly connected to both sides of the rectangular plate, and the other end of the L-shaped rod is fixedly connected to one end of the second hydraulic cylinder. The other end of the second hydraulic cylinder is fixedly connected to the baffle.

[0007] Furthermore, the combined diameter of the semi-circular grooves is smaller than the diameter of the impact ball.

[0008] Furthermore, the impact testing assembly also includes a vertical plate, a third hydraulic cylinder, and a rubber plate. The vertical plate is fixedly connected to both sides of the metal platform, one end of the third hydraulic cylinder is fixedly connected to the side of the vertical plate, and the other end of the third hydraulic cylinder is fixedly connected to the rubber plate.

[0009] Furthermore, it also includes a lubrication assembly, which includes a circular groove, an L-shaped oil supply pipe, and an oil storage tank. The circular groove is formed through the ceramic guide sleeve, and there are a total of four circular grooves. One end of the L-shaped oil supply pipe is fixedly connected to the circular groove, and the other end of the L-shaped oil supply pipe is fixedly inserted into the oil storage tank.

[0010] Furthermore, the lubrication assembly also includes a valve, which is installed on the L-shaped oil delivery pipe.

[0011] This utility model has the following beneficial effects: In this invention, the horn tube in the anti-deviation component adopts a structure that is wider at the top and narrower at the bottom. Even if the impact ball deviates slightly due to friction when it separates from the baffle, it can still be guided to the central area by the inclined inner wall of the horn tube during its fall, and smoothly enter the ceramic guide sleeve. The ceramic guide sleeve, through its inner wall limitation, can forcibly correct the trajectory of the impact ball, ensuring that the impact ball accurately hits the preset impact point of the glass after leaving the ceramic guide sleeve. This completely avoids the problem of "large deviation in landing point due to long-distance fall", significantly improves the accuracy of impact test results, and provides reliable data support for the accurate determination of the impact resistance performance of photovoltaic glazed glass.

[0015] 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.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-6 As shown, this utility model is an impact testing device for high-strength, impact-resistant photovoltaic coated glass, comprising: The impact testing assembly includes a metal stage 101, a first hydraulic cylinder 103, a rectangular plate 104, a baffle 105, and an impact ball 106. The metal stage 101 is fixedly connected to the bottom end of the first hydraulic cylinder 103 on its side, the first hydraulic cylinder 103 is fixedly connected to the top end of the rectangular plate 104, the front end of the rectangular plate 104 is movably connected to the baffle 105, and the impact ball 106 is movably connected between the baffles 105. The anti-deviation component includes a cylindrical bending rod 201, a horn tube 202, and a ceramic guide sleeve 203. One end of the cylindrical bending rod 201 is fixedly connected to the side of the first hydraulic cylinder 103, and the other end of the cylindrical bending rod 201 is fixedly connected to the ceramic guide sleeve 203. The top of the ceramic guide sleeve 203 is fixedly connected to the horn tube 202. The horn tube 202 has an overall structure that is wider at the top and narrower at the bottom. The top of the metal platform 101 is used to place the photovoltaic enamel glass to be impact tested. The first hydraulic cylinder 103 is used to drive the rectangular plate 104 to move up and down, and at the same time, it can drive the baffle 105 to move up and down synchronously, thereby realizing the adjustment of different test heights. The baffle 105 is used to place the impact ball 106. The cylindrical bending rod 201 is used to connect the ceramic guide sleeve 203. The horn tube 202 with a structure that is wider at the top and narrower at the bottom is set above the ceramic guide sleeve 203, which provides a guarantee for the offset impact ball 106 to smoothly enter the ceramic guide sleeve 203. The ceramic guide sleeve 203 can limit and correct the falling path of the impact ball 106, ensuring that the impact ball 106 accurately hits the expected landing point after leaving the ceramic guide sleeve 203.

[0018] The impact testing assembly also includes a semi-circular groove 107, an L-shaped rod 108, and a second hydraulic cylinder 109. The side of the baffle 105 has a semi-circular groove 107, and the semi-circular grooves 107 are movably connected to the impact ball 106. The two sides of the rectangular plate 104 are fixedly connected to one end of the L-shaped rod 108, and the other end of the L-shaped rod 108 is fixedly connected to one end of the second hydraulic cylinder 109. The other end of the second hydraulic cylinder 109 is fixedly connected to the baffle 105. The diameter of the semi-circular grooves 107 after combination is smaller than the diameter of the impact ball 106. L-shaped rod 108 is used to connect rectangular plate 104 and second hydraulic cylinder 109. The second hydraulic cylinder 109 is initially in an extended state, at which time the two baffles 105 are in contact with each other. The size of the two semi-circular grooves 107 is set to prevent the impact ball 106 from falling in this state. When the second hydraulic cylinder 109 is opened, the second hydraulic cylinder 109 retracts and separates from the baffles 105, so that the impact ball 106 can fall smoothly from the two semi-circular grooves 107.

[0019] The impact testing assembly also includes a vertical plate 1010, a third hydraulic cylinder 1011, and a rubber plate 1012. The vertical plate 1010 is fixedly connected to both sides of the metal platform 101, one end of the third hydraulic cylinder 1011 is fixedly connected to the side of the vertical plate 1010, and the other end of the third hydraulic cylinder 1011 is fixedly connected to the rubber plate 1012. The vertical plate 1010 provides a guarantee for the installation of the third hydraulic cylinder 1011, which is used to drive the rubber plate 1012 to move up and down, thereby achieving a firm installation of the glass to be tested.

[0020] Working principle: The high-strength, impact-resistant photovoltaic enamel glass to be tested is placed stably on the top testing area of ​​the metal platform 101. The third hydraulic cylinder 1011 on the side of the vertical plate 1010 is activated, controlling the extension of the third hydraulic cylinder 1011 to push the rubber plate 1012 towards the glass until the rubber plate 1012 is tightly attached to both sides of the glass, thus firmly fixing the glass. The second hydraulic cylinder 109 is then controlled to be in the extended state, so that the two baffles 105 approach and contact each other. At this time, the semi-circular grooves 107 on the side of the baffles 105 combine to form a temporary placement structure. The impact ball 106 is placed in the combined area of ​​the semi-circular grooves 107. According to the testing requirements (such as the height corresponding to different impact energies), the first hydraulic cylinder 103 is activated, controlling the extension or retraction of the first hydraulic cylinder 103, which drives the rectangular plate 104, baffles 105, and... The impact ball 106 moves up and down synchronously until it reaches the preset test height. Then, the first hydraulic cylinder 103 is closed and locked in place, and the second hydraulic cylinder 109 is activated. The second hydraulic cylinder 109 is controlled to retract, causing the two baffles 105 to separate to both sides. The combined structure of the semi-circular groove 107 disintegrates, and the impact ball 106 loses support and begins to fall freely. If the impact ball 106 deviates slightly due to the friction of the baffles 105 in the early stage of its fall, it will first contact the horn tube 202 (the upper wide and lower narrow structure can guide the impact ball 106 to converge towards the center) during the fall. Then, it enters the ceramic guide sleeve 203. The ceramic guide sleeve 203 corrects the falling path of the impact ball 106 through the inner wall limit, ensuring that after the impact ball 106 leaves the ceramic guide sleeve 203, it accurately hits the preset impact point of the glass, completing one impact test.

[0021] Please see Figure 1-6 As shown, this embodiment, based on the above embodiment, further includes: The lubrication assembly includes a circular groove 301, an L-shaped oil delivery pipe 302, and an oil reservoir 303. The circular groove 301 is formed through the ceramic guide sleeve 203, and there are a total of four circular grooves 301. One end of the L-shaped oil delivery pipe 302 is fixedly connected to the circular groove 301, and the other end of the L-shaped oil delivery pipe 302 is fixedly inserted into the oil reservoir 303. The lubrication assembly also includes a valve 304, which is installed on the L-shaped oil delivery pipe 302. The circular groove 301 provides a guarantee for the installation of the L-shaped oil pipe 302. The oil tank 303 is used to store lubricating oil, and the valve 304 is used to control the flow and blockage of lubricating oil in the L-shaped oil pipe 302. The lubricating oil flowing out of the four L-shaped oil pipes 302 can evenly coat the inner wall of the ceramic guide sleeve 203 with lubricating oil, thereby ensuring the rapid fall of the impact ball 106 and avoiding the loss of kinetic energy of the impact ball 106 due to excessive friction.

[0022] Working principle: When valve 304 is opened, the lubricating oil in the oil tank 303 flows into the circular groove 301 of the ceramic guide sleeve 203 through the L-shaped oil supply pipe 302. Because the four L-shaped oil supply pipes 302 are evenly distributed, the lubricating oil can spread evenly along the inner wall of the ceramic guide sleeve 203 to form a thin lubricating film. After observing that the inner wall of the ceramic guide sleeve 203 is evenly coated with oil, valve 304 is closed to stop the oil supply. The second hydraulic cylinder 109 is started to separate the baffle 105, and the impact ball 106 falls. After being guided into the ceramic guide sleeve 203 through the horn 202, the friction between the impact ball 106 and the ceramic guide sleeve 203 is greatly reduced due to the effect of the inner wall lubricating film. It can pass through the ceramic guide sleeve 203 quickly and without kinetic energy loss, accurately hitting the preset impact point of the glass, reducing the impact energy loss caused by friction, and improving the accuracy of the test data.
