The gas gun is usually placed at the end of the airport runway. It will emit a huge sound regularly to scare away birds, and the gas gun usually uses a gas supply pipeline to supply gas.

[0003] In the prior art, the gas supply pipeline of the gas gun mainly uses a solenoid valve to regulate the gas flow rate during gas transportation. However, during the process of transporting gas through the gas supply pipeline of the gas gun, impurities in the gas are likely to adhere to the inner wall of the pipeline. When too many impurities adhere to the inner wall of the pipeline near the solenoid valve, it will affect the sealing performance of the solenoid valve, resulting in difficult precise regulation of the gas flow rate. Therefore, in view of the above problems, we propose a novel gas supply pipeline structure of a gas gun solenoid valve. Summary of the Utility Model

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, this utility model provides a gas supply pipeline structure for a solenoid valve of a gas cannon, including a solenoid valve body 1. An inlet pipe 12 is provided on the left side of the solenoid valve body 1. A connection pipe 31 is provided on the left side of the inlet pipe 12. An external gas supply pipeline 24 is provided on the left side of the connection pipe 31. A second bearing 33 is fixedly connected to the outer surface of the external gas supply pipeline 24 near the right end. A first bearing 32 is fixedly connected to the outer surface of the connection pipe 31 near the left end. A gear sleeve 42 is fixedly connected between the outer surfaces of the second bearing 33 and the first bearing 32. A connection ring 43 is fixedly connected to the inner wall of the gear sleeve 42. Scrapers 44 are fixedly connected to the inner wall of the connection ring 43 at equal intervals. A connection shell 3 is fixedly connected between the outer surfaces of the connection pipe 31 and the external gas supply pipeline 24. A motor base 25 is fixedly connected to the outer surface of the external gas supply pipeline 24 near the lower side. A driving motor 4 is installed at the bottom of the motor base 25. The output end of the driving motor 4 is fixedly connected to a gear column 41. The outer surface of the gear column 41 is meshed with the outer surface of the gear sleeve 42. The inner walls of the external gas supply pipeline 24, the connection pipe 31 and the inlet pipe 12 are all in contact with the outer surface of the scraper 44.

[0023] The effect achieved by the entire Embodiment 1 is that when gas is transported to the gas gun through the external gas supply pipeline 24 for use, impurities in the gas will adhere to the inner wall of the entire pipeline structure. The driving motor 4 is regularly started to drive the gear column 41 to rotate. Since the inner wall of the gear sleeve 42 is connected to the outside of the external gas supply pipeline 24 and the connecting pipeline 31 through the first bearing 32 and the second bearing 33, it can rotate flexibly. The surface of the gear sleeve 42 meshes with the surface of the gear column 41. Therefore, when the gear column 41 rotates, it will drive the gear sleeve 42 to rotate. During the rotation of the gear sleeve 42, the connecting ring 43 on its inner wall will drive the scraper 44 to rotate inside the intake pipe 12, the connecting pipeline 31 and the external gas supply pipeline 24 close to the solenoid valve body 1, thereby scraping off the impurities on the inner wall of the pipeline close to the solenoid valve body 1, preventing them from adhering to the pipe wall in large quantities, and thus avoiding affecting the sealing performance of the solenoid valve body 1 and ensuring the adjustment accuracy of the gas flow. After the adhered impurities are scraped off, they will be transported to the gas gun through the outlet pipe 11 of the solenoid valve body 1 along with the gas for use, and can be filtered and discharged through the filtering mechanism in the gas gun during the process. The connecting shell 3 is mainly used to connect the connecting pipeline 31 and the external gas supply pipeline 24 and maintain the sealing between the two. The motor base 25 is mainly used to install the driving motor 4.

[0024] Embodiment 2 is as Figures 1-4 shown. A second sealing ring 22 is adhesively connected to the right end of the connecting pipeline 31, and a first sealing ring 2 is adhesively connected to the left end of the intake pipe 12. The left surface of the first sealing ring 2 is provided with first meshing teeth 21, and the right surface of the second sealing ring 22 is provided with second meshing teeth 23. The first meshing teeth 21 and the second meshing teeth 23 are arranged in an interleaved and fitting manner. The right side of the solenoid valve body 1 is provided with a supporting outlet pipe 11.

[0025] The effect achieved by the entire Embodiment 2 is that when the connecting pipeline 31 and the outlet pipe 11 of the solenoid valve body 1 are connected through a flange, the first sealing ring 2 and the second sealing ring 22 are provided to improve the sealing performance, and the first meshing teeth 21 and the second meshing teeth 23 that are interleaved and meshed on the surfaces of the first sealing ring 2 and the second sealing ring 22 can further improve the sealing performance between the first sealing ring 2 and the second sealing ring 22, thereby effectively avoiding gas leakage and potential safety hazards.

[0026] Working principle: When gas is transported to the gas cannon through the external gas supply pipeline 24 for use, impurities in the gas will adhere to the inner wall of the entire pipeline structure. The driving motor 4 is regularly started to drive the gear column 41 to rotate. When the gear column 41 rotates, it will drive the gear sleeve 42 to rotate. During the rotation of the gear sleeve 42, the connecting ring 43 on its inner wall will drive the scraper 44 to rotate inside the intake pipe 12, connecting pipe 31 and external gas supply pipeline 24 near the solenoid valve body 1, thereby scraping off the impurities on the inner wall of the pipeline near the solenoid valve body 1, preventing them from adhering to the pipe wall in large quantities, thus avoiding affecting the sealing performance of the solenoid valve body 1 and ensuring the adjustment accuracy of the gas flow. When the connecting pipe 31 and the outlet pipe 11 of the solenoid valve body 1 are connected through a flange, the first sealing ring 2 and the second sealing ring 22 are provided to improve the sealing performance. Moreover, the first engaging teeth 21 and the second engaging teeth 23 that are staggered and engaged on the surfaces of the first sealing ring 2 and the second sealing ring 22 can further improve the sealing performance between the first sealing ring 2 and the second sealing ring 22, thereby effectively avoiding gas leakage and potential safety hazards.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
