Description

Technical Field

[0001] The present invention relates to the technical field of quantum information, and in particular, to a pantograph-catenary arc simulation test device based on CNN. Background Art

[0002] The pantograph-catenary system is an important system for railway electric locomotives to obtain electrical energy through sliding friction. A good pantograph-catenary relationship is the basic premise to ensure the stable and reliable current collection of electric locomotives. However, due to the carbon skateboard of the pantograph installed on the roof of the railway electric locomotive, when it moves at high speed through the relatively stationary catenary, the pantograph-catenary system will generate vibrations of a specific form. When the vibration is severe, it will cause the pantograph skateboard to disengage from the contact wire, forming an off-line situation, generating arcs and sparks, accelerating the insulation damage of the pantograph-catenary system equipment and other electrical equipment, generating electromagnetic interference to communication, and more seriously, directly affecting the current collection, and even causing an instantaneous power supply interruption, making the electric locomotive lose traction and braking force. These complex environmental factors make the characteristics of the pantograph-catenary arc extremely complex, which leads to difficulties for researchers to deeply analyze the generation mechanism, development process of the pantograph-catenary arc under different working conditions and its impact on the entire power supply system. Therefore, there is a particular need for a pantograph-catenary arc simulation test device based on CNN.

[0003] However, traditional research methods are difficult to comprehensively and accurately simulate and analyze it. Without a test device, directly testing the device on a railway electric locomotive is difficult to precisely control and simulate various working conditions as in a test device. For example, for harsh weather conditions or bumpy road conditions, accurate test data under all key working conditions may not be obtained, resulting in an incomplete and inaccurate performance evaluation of the pantograph-catenary arc simulation test device based on CNN, and unable to fully verify its effectiveness and reliability under various actual operating conditions.

[0028] The bump simulation mechanism 5 includes a protective housing 501, a bump motor 502, a driving rotating shaft 503, a belt 504, a driven rotating shaft 505, a bump block 506, a bump plate 507, a vibration equalizing spring 508, and a connecting plate 509. The upper surface of the lower base 2 is fixedly connected with the protective housing 501. The inner surface of the protective housing 501 is fixedly connected with the bump motor 502. One side surface of the bump motor 502 is fixedly connected with the driving rotating shaft 503. One side surface of the driving rotating shaft 503 is attached to the belt 504. One side surface of the belt 504 is attached to the driven rotating shaft 505. One side surface of the driven rotating shaft 505 is fixedly connected with the bump block 506. The upper surface of the bump block 506 is movably connected with the bump plate 507. The upper surface of the bump plate 507 is fixedly connected with the vibration equalizing spring 508. The upper surface of the vibration equalizing spring 508 is fixedly connected with the connecting plate 509. Through the settings of the protective housing 501, the bump motor 502, the driving rotating shaft 503, the belt 504, the driven rotating shaft 505, the bump block 506, the bump plate 507, the vibration equalizing spring 508, and the connecting plate 509, during use, the bump motor 502 drives the rotation of the driving rotating shaft 503, and the driving rotating shaft 503 drives the other six driven rotating shafts 505 to rotate through the belt 504.

And the three groups of bump blocks 506 arranged on the outer surfaces of the driving rotating shaft 503 and each group of driven rotating shafts 505 can cooperate with the vibration damping springs 508 to better simulate the bumps in reality and improve the accuracy of data collection.

[0031] Further, one group of vibration damping springs 508 is arranged at each of the four corners of the bump plate 507, and eight springs in each group are symmetrically arranged at equal intervals. The connecting plate 509 is fixedly connected to the inner surface of the first-layer guard plate 4. Through the arrangement of the vibration damping springs 508, during use, this layout can make the spring forces received by each part of the bump plate 507 more uniform when the bump plate 507 is subjected to external impacts or vibrations, and cooperate with the three groups of bump blocks 506 to better simulate the bumps in reality and improve the accuracy of data collection.

[0032] Further, the motion simulation mechanism 9 includes an unwinding roller 901, a wire 902, an unwinding motor 903, a main wire offset groove 904, a rotating threaded column 905, a wire offset motor 906, a first limiting groove 907, a connecting column 908, a driven wire offset groove 909, a sliding rod 910, a second limiting groove 911, a winding roller 912 and a winding motor 913. The upper surface of the lower base 2 is fixedly connected with the unwinding roller 901. The wire 902 is wound around the outer surface of the unwinding roller 901. One side surface of the unwinding roller 901 is fixedly connected with the unwinding motor 903. One side surface of the wire 902 is slidably connected with the main wire offset groove 904. One side surface of the main wire offset groove 904 is slidably connected with the rotating threaded column 905. One side surface of the rotating threaded column 905 is fixedly connected with the wire offset motor 906. One side surface of the main wire offset groove 904 is slidably connected with the first limiting groove 907. One side surface of the first limiting groove 907 is fixedly connected with the connecting column 908. One side surface of the wire 902 is slidably connected with the driven wire offset groove 909.

At this time, the wire offset motor 906 drives the rotating threaded column 905 to move the main wire offset groove 904 left and right, driving the wire 902 to slide left and right while being unwound, simulating the "zigzag" swing of the wire 902 in reality. And the winding motor 913 drives the winding roller 912 to wind the wire 902. The movement is flexible and accurate, covering a variety of motion scenarios, reflecting the relative position changes during actual operation, and improving the accuracy of data during testing.

[0033] Further, the active wire offset groove 904 is slidably connected to the first limiting groove 907 through the setting of the rotating threaded column 905. A set of connecting columns 908 are symmetrically arranged on both side surfaces of the first limiting groove 907 and the second limiting groove 911. Through the settings of the active wire offset groove 904, the rotating threaded column 905 and the first limiting groove 907, during use, with the cooperation of the rotating threaded column 905 and the sliding connection, the position of the active wire offset groove 904 in the first limiting groove 907 can be precisely controlled by rotating the threaded column, achieving precise displacement adjustment, meeting the requirements for position accuracy in different working scenarios. Moreover, the threaded connection itself has good self-locking performance, enabling the active wire offset groove 904 to remain stable after being adjusted to the appropriate position, and not being easily displaced randomly due to factors such as vibration and external forces, ensuring the stability of the entire structure during the working process.

[0034] Further, the driven wire offset groove 909 is slidably connected left and right in the second limiting groove 911 through the settings of the active wire offset groove 904 and the wire 902. The outer dimensions of the unwinding roller 901 and the winding roller 912 are in line with each other. Through the settings of the unwinding roller 901 and the winding roller 912, during use, since the outer dimensions of the unwinding roller 901 and the winding roller 912 are in line with each other, it can keep the wire under uniform tension and have a stable running track during the winding and unwinding process, avoiding situations such as the wire running off track, overlapping or becoming loose on the rollers, ensuring the neat and orderly winding and unwinding of the wire, which is beneficial to improving production quality and efficiency.

[0035] Further, the environment simulation mechanism 10 includes a second-layer guard plate 1001, a circular slide rail 1002, a sunlight simulation lamp 1003, a water volume adjustment disc 1004, and a rain simulation nozzle 1005.

Through the settings of the second-layer guard plate 1001, the circular slide rail 1002, the sunlight simulation lamp 1003, the water volume adjustment disc 1004, and the rain simulation nozzle 1005, during use, the sunlight simulation lamp 1003 can move to a suitable position on the circular slide rail 1002 for irradiation according to requirements, and the water volume adjustment disc 1004 adjusts the rain simulation nozzle 1005 to simulate rainfall in reality, which is more comprehensive and accurate, making it verify its effectiveness and reliability under various actual operating conditions.

[0036] Further, a set of two - layer guard plates 1001 is provided on the upper surface of each set of one - layer guard plates 4. The sunlight simulation lamp 1003 can swing vertically when rotating above the circular slide rail 1002. Through the settings of the circular slide rail 1002 and the sunlight simulation lamp 1003, during use, it can swing vertically at different angles and positions, and can more realistically simulate the changes in the illumination angle and intensity of the sun at different times and seasons, providing more accurate lighting conditions for experiments, research, or application scenarios that require simulating natural light, such as plant cultivation experiments, solar product testing, etc.

[0037] Further, multiple groups of rain - water simulation nozzles 1005 are symmetrically arranged at equal intervals on the lower surface of the water volume adjustment disk 1004. The two - layer guard plate 1001 is fixedly connected to the water volume adjustment disk 1004 through four columns. Through the setting of the rain - water simulation nozzles 1005, during use, the equal - interval symmetrical arrangement can ensure a relatively uniform precipitation simulation effect within the coverage area of the rain - water simulation nozzles 1005 when spraying water, avoiding situations where the local water volume is too much or too little, enabling the object or area to be tested to be evenly washed, which is beneficial to improving the accuracy and reliability of rain - water simulation and can more realistically reflect the actual situation.

[0038] Working principle: This pantograph-catenary arc simulation test device based on CNN, through the setting of the bump simulation mechanism 5, the bump motor 502 drives the rotation of the active rotating shaft 503. The active rotating shaft 503 drives the rotation of the other six driven rotating shafts 505 through the belt 504. This will cause the bump block 506 to drive the bump plate 507 to vibrate slightly. At the same time, since the uniform vibration spring 508 is fixedly connected to the upper surface of the bump plate 507, its vibration more simulates the actual vibration feeling, generating a complex bump effect, which can consider the influence of mechanical vibration on the pantograph-catenary arc, making the pantograph feel a more real working condition. Through the setting of the motion simulation mechanism 9, the unwinding motor 903 drives the unwinding roller 901 to unwind the wire 902. At this time, the wire offset motor 906 drives the rotating threaded column 905 to move the active wire offset groove 904 left and right, driving the wire 902 to slide left and right while being unwound, simulating the "zigzag" swing of the wire 902 in reality. The winding motor 913 drives the winding roller 912 to wind the wire 902. The movement is flexible and accurate, covering a variety of motion scenarios, reflecting the relative position changes in actual operation, and improving the accuracy of data during testing. Through the setting of the environment simulation mechanism 10, the sunlight simulation lamp 1003 can move and irradiate at a suitable position on the circular slide rail 1002 according to requirements, and the water volume adjustment disk 1004 adjusts the rain simulation nozzle 1005 to simulate rainfall in reality, which is more comprehensive and accurate, making it verify its effectiveness and reliability under various actual operating conditions.
