A photovoltaic panel impact resistance testing device

Abstract

This invention belongs to the technical field of photovoltaic panel testing equipment, specifically a photovoltaic panel impact resistance testing device, including multiple testing frames. Each testing frame has an internal flipping mechanism and a displacement mechanism. A top cover is provided on the top of each testing frame, and an operating box is installed between the outer walls of the testing frames. A puck storage box is installed on the outer wall of the top cover, and a limiting component is provided on the inner wall of the testing frame. By changing the rotational speed of the longitudinal gear, the movement trajectory of the puck launcher is altered. The teeth of the second gear mesh with those of the first gear, and their circumferences differ significantly. Therefore, the rotational speeds of the first and second gears are different. When the first gear rotates one revolution, the second gear has already rotated many revolutions. When the puck launcher is controlled to move, the lateral and longitudinal movement speeds differ, and its movement trajectory changes accordingly, thus increasing the randomness of the puck launch position.

Description

Technical Field

[0001] This invention belongs to the technical field of photovoltaic panel testing equipment, specifically a photovoltaic panel impact resistance testing device. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of solid-state photovoltaic cells made almost entirely of semiconductor materials. Because it has no moving parts, it can operate for extended periods without any wear and tear. Simple PV cells can power watches and computers, while more complex PV systems can provide lighting for homes and supply electricity to the grid. PV panel modules can be made in various shapes, and these modules can be connected to generate even more power.

[0003] In existing technologies, the impact resistance testing of photovoltaic panels almost always involves placing the photovoltaic panel in a static state. Although a static photovoltaic panel can be more firmly fixed when subjected to an impact from an ice hockey puck, and this fixing device can also be used for actual installation of photovoltaic panels, it is impossible to detect the angle at which the photovoltaic panel is tilted to minimize the impact force and damage, resulting in insufficient collection of test data.

[0004] Therefore, the present invention provides a photovoltaic panel impact resistance testing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the photovoltaic panel impact resistance testing equipment of the present invention includes multiple testing frames, and the testing frames are provided with a flipping mechanism and a displacement mechanism inside;

[0007] The top of the testing frame is provided with a top cover, an operation box is installed between the outer walls of the testing frame, an ice hockey storage box is provided on the outer wall of the top cover, a limiting component is provided on the inner wall of the testing frame, and a sliding opening is provided on the inner wall of the limiting component.

[0008] Multiple testing racks are used to support the equipment for impact testing of photovoltaic panels. The flipping mechanism is used to control the photovoltaic panel to deflect within a certain angle during testing, so that the photovoltaic panel is in a dynamic state during testing. The displacement mechanism is used to control the position of the ice hockey puck launch, controlling the random launch of ice hockey pucks, and trying to closely match the random impact of ice hockey pucks on the photovoltaic panel in nature. The top cover is used to install the ice hockey puck storage box and install the displacement mechanism inside it. Through the above mechanisms, the system can simulate the state of nature as closely as possible, thus achieving better detection of the impact state of the photovoltaic panel.

[0009] Preferably, the flipping mechanism includes a support plate, a reversing column fixedly disposed between the outer walls of the support plate, flipping gears rotatably connected to both ends of the reversing column, a sector gear disposed on the outer wall of the support plate, a fixing member disposed on the outer wall of the sector gear, a fixing disk disposed on the outer wall of the fixing member, a fixing block disposed on the outer wall of the fixing disk, and a photovoltaic panel disposed between the outer walls of the two fixing blocks. The support plate is rectangular at the bottom, and each end of the rectangular prism has a triangular object. When the photovoltaic panel is controlled by the fixing block and the fixing disk, the simulation state is activated. At this time, one of the flipping gears is controlled to start rotating, driving the other flipping gear to rotate through the reversing column. The flipping gears at both ends simultaneously mesh with the sector gears, controlling the sector gears to rotate around a point on the support plate as the center. The sector gears at both ends control the two ends of the photovoltaic panel to dynamically flip. Through the operation of the flipping mechanism, the photovoltaic panel is controlled to rotate within a certain angle.

[0010] Preferably, the outer wall of the support plate is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a slider, the outer wall of the slider is fixedly connected to a moving part, the teeth of the moving part mesh with the teeth of the flip gear, the teeth of the flip gear mesh with the teeth of the sector gear, when the flip gear rotates, the teeth of the flip gear mesh with the teeth of the moving part, so the flip gear controls the moving part to move back and forth, the slider at the bottom of the moving part is located in the sliding groove to control the movement of the moving part, and the rotation of the flip gear achieves the effect of controlling the displacement of the moving part.

[0011] Preferably, the inner wall of the moving part is threaded with a moving column, the middle section of the moving column is threaded, the two ends of the moving column are fixedly connected with limiting rings, the outer wall of the limiting rings is fixedly connected with a fixed column, the outer wall of the fixed column is rotatably connected with a limiting plate, and the other end of the limiting plate is provided with a sliding column. The sliding column controls the limiting plate to reciprocate linearly in the sliding opening inside the limiting part. The fixed column controls the other end of the limiting plate to rotate the moving column through the limiting rings. When the moving column rotates, because the moving part and the threaded section of the moving column are threadedly connected, when the moving column rotates, the moving part will move on the threaded section of the moving column. Through the cooperation of the limiting plate and the limiting rings, the effect of controlling the moving part to reciprocate linearly in a designated section is achieved.

[0012] Preferably, the inner wall of the limiting member is rotatably connected to a main control column. The inner wall of the limiting member is provided with a first eccentric column and a second eccentric column. The outer wall of the main control column is provided with a main control wheel. The outer walls of the first eccentric column and the second eccentric column are respectively provided with a first eccentric wheel and a second eccentric wheel. The first eccentric wheel is located to the left of the main control wheel, and the second eccentric wheel is located to the right of the main control wheel. There are three eccentric wheels inside the sliding opening. The teeth of the main control wheel mesh with the teeth of the first eccentric wheel and the second eccentric wheel respectively. Therefore, the main control wheel is a power wheel. When the main control wheel rotates, the first eccentric wheel and the second eccentric wheel rotate with it, achieving the effect of controlling the rotation of the first eccentric wheel and the second eccentric wheel through the control wheel.

[0013] Preferably, the teeth of the master control wheel mesh with the teeth of the first eccentric wheel, and the teeth of the master control wheel mesh with the teeth of the second eccentric wheel. A movable plate is fixedly connected to the outer wall of the master control wheel, the first eccentric wheel, and the second eccentric wheel. The outer wall of the movable plate is fixedly connected to the sliding column. When the master control wheel drives the first eccentric wheel and the second eccentric wheel to rotate, the movable plate located on the surface of these three gears will be controlled to move back and forth inside the sliding opening. Subsequently, the movable plate will control the limiting plate to move reciprocally in a straight line. Through the meshing of the gears, the movement of the limiting plate is controlled by the movable plate.

[0014] Preferably, the displacement mechanism includes a lateral displacement plate, one end of which is threadedly connected to a fast-moving column. A following column is provided inside the top cover. Displacement blocks are provided on the outer walls of both the fast-moving column and the following column. A second speed-changing gear is fixedly connected to one end of the following column. The displacement mechanism is used to control the position of the ice hockey puck launch. The lateral displacement plate is controlled by the displacement disk to perform reciprocating linear motion. When the lateral displacement plate moves, the fast-moving column rotates due to the movement of the lateral displacement plate. Then, through the control of the displacement blocks, the following column and the fast-moving column together control the displacement rod to move. Through the cooperation of the following column and the fast-moving column, the effect of the displacement block controlling the following column and the fast-moving column to move at the same frequency is achieved.

[0015] Preferably, a displacement disk is fixedly connected to the other end of the lateral displacement plate. The outer wall of the displacement disk is fixedly connected to the outer wall of the limiting plate. A displacement rod is fixedly connected between the outer walls of the displacement blocks. A displacement connector is slidably connected to the outer wall of the displacement rod. An ice hockey launcher is fixedly connected to the outer wall of the displacement connector. The limiting plate controls the displacement disk to move with it. The displacement plate controls the lateral displacement plate to move. The connector moves laterally under the control of the displacement blocks. The ice hockey launcher is driven by the connector to perform irregular trajectory movement. The ice hockey launcher also randomly launches ice hockeys at the photovoltaic panel.

[0016] Preferably, a rotary cylinder is fixedly installed on the outer wall of the detection frame. The output shaft of the rotary cylinder is fixedly connected to one end of the main control column. When the rotary cylinder is started, the output shaft of the rotary cylinder controls the rotation of the main control column, and the main control column controls the rotation of the main control wheel, providing power for subsequent reciprocating linear operation.

[0017] Preferably, a transverse gear is fixedly connected to the outer wall of the following column, and a second variable speed gear is fixedly connected to the other end of the following column. The teeth of the first variable speed gear and the second variable speed gear mesh with each other. A longitudinal displacement plate is provided on the outer wall of the displacement connector. A longitudinal displacement column is threadedly connected to the outer wall of the longitudinal displacement plate. A longitudinal gear is fixedly connected to one end of the longitudinal displacement column. The teeth of the longitudinal gear mesh with the teeth of the transverse gear. When the longitudinal gear controls the transverse gear to rotate, the transverse gear then controls the second variable speed gear to rotate. The teeth of the second variable speed gear mesh with the teeth of the first variable speed gear, and the circumferences of the two gears differ relatively greatly. Therefore, the rotational speeds of the first variable speed gear and the second variable speed gear are different. When the first variable speed gear rotates once, the second variable speed gear has already rotated many times. Therefore, when the hockey launcher is controlled to move, the transverse and longitudinal movement speeds are different, and its trajectory also changes accordingly. Therefore, the trajectory of the hockey launcher can be changed by changing the rotational speed of the longitudinal gear, thus increasing the randomness of the hockey launch position.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The photovoltaic panel impact resistance testing device of the present invention achieves the effect of changing the motion trajectory of the hockey launcher by changing the rotation speed of the longitudinal gear. When the longitudinal gear controls the rotation of the transverse gear, the transverse gear then controls the rotation of the second gear. The teeth of the second gear mesh with the teeth of the first gear, and the circumferences of the two gears are relatively different. Therefore, the rotation speeds of the first gear and the second gear are different. When the first gear rotates once, the second gear has already rotated many times. Therefore, when the hockey launcher is controlled to move, the transverse and longitudinal movement speeds are different, and its motion trajectory also changes accordingly, thus increasing the randomness of the hockey launch position.

[0020] 2. The photovoltaic panel impact resistance testing equipment of the present invention, through the cooperation of the following column and the fast-moving column, achieves the effect of controlling the moving block to move the following column and the fast-moving column together at the same frequency. The displacement mechanism is used to control the position of the ice hockey puck launch. The lateral displacement plate is controlled by the displacement disk to perform reciprocating linear motion. When the lateral displacement plate moves, the fast-moving column will rotate due to the movement of the lateral displacement plate. Then, through the control of the displacement block, the following column and the fast-moving column are controlled to move together to control the displacement rod. Attached Figure Description

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figure 1 and Figure 6 As shown, an impact testing device for a photovoltaic panel 208 according to an embodiment of the present invention includes multiple testing frames 100, and the testing frame 100 is provided with a flipping mechanism 200 and a displacement mechanism 300 inside;

[0035] The top of the testing rack 100 is provided with a top cover 101, and an operation box 102 is installed between the outer walls of the testing rack 100. An ice hockey storage box 103 is provided on the outer wall of the top cover 101. A limiting member 104 is provided on the inner wall of the testing rack 100, and a sliding opening 105 is provided on the inner wall of the limiting member 104.

[0036] During operation, multiple testing frames 100 are used to support the equipment for impact testing of photovoltaic panels 208. The flipping mechanism 200 is used to control the photovoltaic panels 208 to deflect within a certain angle during testing, so that the photovoltaic panels 208 are in a dynamic state during testing. The displacement mechanism 300 is used to control the position of the ice hockey puck launch, controlling the random launch of ice hockey pucks, and trying to closely simulate the random impact of ice hockey pucks on the photovoltaic panels 208 in nature. The top cover 101 is used to install the ice hockey puck storage box 103 and install the displacement mechanism 300 inside it. Through the above mechanisms, the state of the photovoltaic panels 208 is simulated as closely as possible to simulate the state of nature, which plays a better role in detecting the impact state of the photovoltaic panels 208.

[0037] like Figures 2 to 3 As shown, the flipping mechanism 200 includes a support plate 201, a reversing column 202 fixedly disposed between the outer walls of the support plate 201, a flipping gear 203 rotatably connected to both ends of the reversing column 202, a sector gear 204 disposed on the outer wall of the support plate 201, a fixing member 205 disposed on the outer wall of the sector gear 204, a fixing disk 206 disposed on the outer wall of the fixing member 205, a fixing block 207 disposed on the outer wall of the fixing disk 206, and a photovoltaic panel 208 disposed between the outer walls of the two fixing blocks 207.

[0038] During operation, the support plate 201 has a rectangular bottom and two triangular objects at both ends. When the photovoltaic panel 208 is controlled by the fixing block 207 and the fixing plate 206, the simulation state is activated. At this time, one of the flip gears 203 is controlled to start rotating, which drives the other flip gear 203 to rotate through the reversing column 202. The flip gears 203 at both ends mesh with the sector gears 204 and control the sector gears 204 to rotate around a point on the support plate 201. The sector gears 204 at both ends control the two ends of the photovoltaic panel 208 to dynamically flip. Through the operation of the flipping mechanism 200, the photovoltaic panel 208 is controlled to rotate within a certain angle.

[0039] like Figures 3 to 5 As shown, the outer wall of the support plate 201 is provided with a sliding groove 209, the inner wall of the sliding groove 209 is slidably connected to a slider 210, the outer wall of the slider 210 is fixedly connected to a moving part 211, the teeth of the moving part 211 mesh with the teeth of the flip gear 203, and the teeth of the flip gear 203 mesh with the teeth of the sector gear 204.

[0040] When the reversing gear 203 rotates, its teeth mesh with the teeth of the moving part 211. Therefore, the reversing gear 203 controls the moving part 211 to move back and forth. The slider 210 at the bottom of the moving part 211 is located in the slide groove 209 to control the movement of the moving part 211. The rotation of the reversing gear 203 achieves the effect of controlling the displacement of the moving part 211.

[0041] like Figure 3 and Figure 5 As shown, the inner wall of the movable part 211 is threaded with a movable column 212, the middle section of the movable column 212 is threaded, the two ends of the movable column 212 are fixedly connected with a limiting ring 213, the outer wall of the limiting ring 213 is fixedly connected with a fixed column 214, the outer wall of the fixed column 214 is rotatably connected with a limiting plate 215, and the other end of the limiting plate 215 is provided with a sliding column 216.

[0042] During operation, the sliding column 216 controls the limiting plate 215 to reciprocate linearly within the sliding opening 105 inside the limiting member. The fixed column 214 controls the other end of the limiting plate 215 to rotate the moving column 212 via the limiting ring 213. When the moving column 212 rotates, because the moving part 211 is threaded to the threaded end of the moving column 212, the moving part 211 will move along the threaded section of the moving column 212 when the moving column 212 rotates. Through the cooperation of the limiting plate 215 and the limiting ring 213, the moving part 211 is controlled to reciprocate linearly within the specified section.

[0043] like Figure 6 and Figure 7 As shown, the inner wall of the limiting member 104 is rotatably connected to the main control column 106. The inner wall of the limiting member 104 is provided with a first eccentric column 107 and a second eccentric column 108. The outer wall of the main control column 106 is provided with a main control wheel 109. The outer walls of the first eccentric column 107 and the second eccentric column 108 are respectively provided with a first eccentric wheel 110 and a second eccentric wheel 111. The first eccentric wheel 110 is located to the left of the main control wheel 109, and the second eccentric wheel 111 is located to the right of the main control wheel 109.

[0044] During operation, the sliding port 105 has three eccentric wheels inside. The teeth of the master control wheel 109 mesh with the teeth of the first eccentric wheel 110 and the second eccentric wheel 111, respectively. Therefore, the master control wheel 109 is a power wheel. When the master control wheel 109 rotates, the first eccentric wheel 110 and the second eccentric wheel 111 also rotate with it, achieving the effect of controlling the rotation of the first eccentric wheel 110 and the second eccentric wheel 111 through the control wheel.

[0045] like Figure 7 As shown, the teeth of the main control wheel 109 mesh with the teeth of the first eccentric wheel 110, and the teeth of the main control wheel 109 mesh with the teeth of the second eccentric wheel 111. A movable plate 112 is fixedly connected to the outer wall of the main control wheel 109, the first eccentric wheel 110 and the second eccentric wheel 111. The outer wall of the movable plate 112 is fixedly connected to the sliding column 216.

[0046] During operation, when the main control wheel 109 drives the first eccentric wheel 110 and the second eccentric wheel 111 to rotate, the movable plate 112 located on the surface of these three gears will be controlled to move back and forth inside the sliding port 105. Subsequently, the movable plate 112 will control the limiting plate 215 to move back and forth in a straight line. Through the meshing of the gears, the movable plate 112 controls the movement of the limiting plate 215.

[0047] like Figures 8 to 9As shown, the displacement mechanism 300 includes a transverse displacement plate 301, one end of which is threadedly connected to a fast-moving column 303, and a following column 305 is provided inside the top cover 101. Both the fast-moving column 303 and the following column 305 are provided with displacement blocks 306 on their outer walls, and one end of the following column 305 is fixedly connected to a second speed-changing gear 316.

[0048] During operation, the displacement mechanism 300 is used to control the position of the ice hockey puck launch. The lateral displacement plate 301 is controlled by the displacement disk 307 to perform reciprocating linear motion. When the lateral displacement plate 301 moves, the fast-moving column 303 will rotate due to the movement of the lateral displacement plate 301. Then, under the control of the displacement block 306, it moves together with the moving column 305 and the fast-moving column 303 to control the displacement rod 308 to move. Through the cooperation of the moving column 305 and the fast-moving column 303, the displacement block 306 achieves the effect of controlling the moving column 305 and the fast-moving column 303 to move at the same frequency.

[0049] like Figure 6 and Figure 9 As shown, a displacement disk 307 is fixedly connected to the other end of the transverse displacement plate 301. The outer wall of the displacement disk 307 is fixedly connected to the outer wall of the limiting plate 215. A displacement rod 308 is fixedly connected between the outer walls of the displacement blocks 306. A displacement connector 309 is slidably connected to the outer wall of the displacement rod 308. An ice hockey launcher 310 is fixedly connected to the outer wall of the displacement connector 309.

[0050] During operation, the limiting plate 215 controls the displacement disk 307 to move accordingly, the displacement plate controls the lateral moving plate 112 to move, the connecting piece is controlled by the displacement block 306 to move laterally, the ice hockey launcher 310 is driven by the connecting piece to perform regular trajectories, and the ice hockey launcher 310 also randomly launches ice hockey balls towards the photovoltaic panel 208.

[0051] like Figure 8 As shown, a rotary cylinder 311 is fixedly installed on the outer wall of the testing frame 100, and the output shaft of the rotary cylinder 311 is fixedly connected to one end of the main control column 106;

[0052] During operation, the rotary cylinder 311 is activated, and the output shaft of the rotary cylinder 311 controls the rotation of the main control column 106, which in turn controls the rotation of the main control wheel 109, providing power for subsequent reciprocating linear motion.

[0053] like Figures 9 to 10As shown, a transverse gear 312 is fixedly connected to the outer wall of the shift column 305, and a second gear 316 is fixedly connected to the other end of the shift column 305. The teeth of the first gear 317 and the second gear 316 mesh with each other. A longitudinal displacement plate 313 is provided on the outer wall of the displacement connector 309. A longitudinal displacement column 314 is threadedly connected to the outer wall of the longitudinal displacement plate 313. A longitudinal gear 315 is fixedly connected to one end of the longitudinal displacement column 314. The teeth of the longitudinal gear 315 mesh with the teeth of the transverse gear 312.

[0054] During operation, when the longitudinal gear 315 controls the rotation of the transverse gear 312, the transverse gear 312 subsequently controls the rotation of the second gear 316. The teeth of the second gear 316 mesh with the teeth of the first gear 317, and the circumferences of the two gears differ relatively greatly. Therefore, the rotational speeds of the first gear 317 and the second gear 316 are different. When the first gear 317 rotates one revolution, the second gear 316 has already rotated many revolutions. As a result, when the hockey launcher 310 is controlled to move, the transverse and longitudinal movement speeds are different, and its trajectory changes accordingly. Therefore, the trajectory of the hockey launcher 310 can be changed by varying the rotational speed of the longitudinal gear 315, thereby increasing the randomness of the hockey launch position.

[0055] Working principle: Multiple testing frames 100 support the equipment for impact testing of photovoltaic panels 208. A flipping mechanism 200 controls the photovoltaic panel 208 to deflect within a certain angle during testing, keeping it in a dynamic state. A displacement mechanism 300 controls the position of the ice hockey puck launch, controlling the random launch of the puck to closely simulate the impact of the puck on the photovoltaic panel 208 in nature. A top cover 101 houses the ice hockey puck storage box 103 and internally installs the displacement mechanism 300. These mechanisms closely simulate natural conditions, effectively detecting the impact state of the photovoltaic panel 208. A rotary cylinder 311 is activated, and its output shaft controls the rotation of the main control column 106. The main control column 106 controls the rotation of the main control wheel 109, providing power for subsequent reciprocating linear motion. The sliding port 105 contains three eccentric wheels. The teeth of the main control wheel 109 mesh with the teeth of the first eccentric wheel 110 and the second eccentric wheel 111, making the main control wheel 109 the power wheel. When the main control wheel 109 rotates, the first eccentric wheel 110 and the second eccentric wheel 111 rotate accordingly, achieving the effect of controlling the rotation of the first eccentric wheel 110 and the second eccentric wheel 111 through the control wheel. When the main control wheel 109 drives the first eccentric wheel 110 and the second eccentric wheel 111 to rotate, the moving plate 112 located on the surface of these three gears is controlled to move back and forth inside the sliding port 105. Subsequently, the moving plate 112 controls... The limiting plate 215 reciprocates linearly. Through gear meshing, the moving plate 112 controls the movement of the limiting plate 215. The sliding column 216 controls the limiting plate 215 to reciprocate linearly within the sliding opening 105 inside the limiting member. The fixed column 214 controls the other end of the limiting plate 215 to rotate the moving column 212 via the limiting ring 213. When the moving column 212 rotates, because the moving member 211 is threaded to the threaded end of the moving column 212, the moving member 211 moves along the threaded section of the moving column 212. Through the cooperation of the limiting plate 215 and the limiting ring 213, the moving member 211 is controlled to reciprocate linearly within a designated section. The linear motion effect is achieved by using a support plate 201 with a cuboid bottom and triangular-shaped objects at both ends. When the photovoltaic panel 208 is controlled by the fixing block 207 and the fixing disk 206, the simulation state is activated. At this time, one of the rotating gears 203 is controlled to rotate. When the rotating gear 203 rotates, its teeth mesh with the teeth of the moving part 211, thus controlling the moving part 211 to move back and forth. The slider 210 at the bottom of the moving part 211 is located in the slide groove 209, controlling the movement of the moving part 211. The rotation of the rotating gear 203 achieves the effect of controlling the displacement of the moving part 211. The reverse column 202 drives the other rotating gear 203 to rotate.The flipping gears 203 at both ends mesh with the sector gears 204 simultaneously, controlling the sector gears 204 to rotate around a point on the support plate 201. The sector gears 204 at both ends control the two ends of the photovoltaic panel 208 to dynamically flip. Through the operation of the flipping mechanism 200, the photovoltaic panel 208 is controlled to rotate within a certain angle. The limiting plate 215 controls the displacement disk 307 to move with it. The displacement plate controls the lateral moving plate 112 to move. The connecting piece is controlled by the displacement block 306 to move laterally. The hockey launcher 310 is driven by the connecting piece to move in an irregular trajectory. The hockey launcher 310 also randomly launches hockey balls at the photovoltaic panel 208. The displacement mechanism 300 is used to control the position of the hockey ball launch. The lateral displacement plate 301 is controlled by the displacement disk 307 to move in a reciprocating linear motion. When the lateral displacement plate 301 moves, the speed-shifting column 303 will rotate due to the movement of the lateral displacement plate 301, and then rotates with it under the control of the displacement block 306. The follower column 305 and the high-speed shift column 303 together control the movement of the displacement rod 308. Through the cooperation of the follower column 305 and the high-speed shift column 303, the displacement block 306 achieves the effect of controlling the follower column 305 and the high-speed shift column 303 to move at the same frequency. When the longitudinal gear 315 controls the rotation of the transverse gear 312, the transverse gear 312 subsequently controls the rotation of the second gear 316. The teeth of the second gear 316 mesh with the teeth of the first gear 317, and the difference in their circumferences is relatively large. Therefore, the rotational speeds of the first gear 317 and the second gear 316 are different. When the first gear 317 rotates one revolution, the second gear 316 has already rotated many revolutions. Therefore, when the hockey launcher 310 is controlled to move, the transverse and longitudinal movement speeds are different, and its trajectory changes accordingly. Thus, the trajectory of the hockey launcher 310 can be changed by varying the rotational speed of the longitudinal gear 315, thereby increasing the randomness of the hockey launch position.
