[0002] The medium and short wave transmitters in radio and television stations are responsible for converting audio information such as voices and music into radio signals for transmission. Medium wave transmitters are mainly used for domestic and regional broadcasts, and the signals can penetrate buildings and terrain obstacles well, covering a large number of listeners; short wave transmitters are good at international broadcasts and long-distance communications, and the signals can cross national boundaries to achieve long-distance information transmission.

[0003] The function of the medium and short wave transmitter is to send the program content produced by the radio station to the radios of listeners in the form of radio waves, so that people can listen to radio programs anytime and anywhere. When using the medium and short wave transmitter, it is necessary to connect the transmitter interface. When the interface of the transmitter is not used for a long time, dust and impurities in the air will adhere to the surface of the core wire of the transmitter.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figures 1 - 15 , the present invention provides a technical solution: a short-wave transmitter fault warning device in a radio and television station, including a transmitter main body 1, the transmitter main body 1 is provided with a transmission interface 11, a core wire 12 is arranged inside the transmission interface 11, and the transmission interface 11 is connected to a transmission joint 13;

[0042] A dust-proof mechanism 2, the dust-proof mechanism 2 is located at the end of the transmission interface 11, and the dust-proof mechanism 2 prevents dust from entering the inside of the transmission interface 11;

[0043] A cleaning mechanism 3, the cleaning mechanism 3 is located inside the transmission interface 11, and the cleaning mechanism 3 can clean the core wire 12 when the transmission joint 13 is inserted into the inside of the transmission interface 11;

[0044] When the present invention is in use, when the transmitter main body 1 is not in use, the dust-proof mechanism 2 can be used to prevent dust from the transmission interface 11, avoiding dust and impurities from adhering to the inside of the transmission interface 11. When accessing the transmission interface 11, the cleaning mechanism 3 can clean the oxides and rust on the surface of the core wire 12, avoiding the increase of the contact resistance of the core wire 12 caused by rust, oxides, etc.

[0045] The dust-proof mechanism 2 includes two springs 21 fixedly connected to the outer wall of the transmitter main body 1. The two springs 21 are respectively located on both sides of the transmission interface 11. One end of the spring 21 away from the transmitter main body 1 is fixedly connected to a sliding plate 22. A sliding hole 23 is opened in the center of the sliding plate 22. The transmission interface 11 is located in the sliding hole 23 and is slidably connected to the sliding hole 23. One end of the sliding plate 22 away from the transmitter main body 1 is provided with a dust-proof member 4 that can prevent dust from entering the inside of the transmission interface 11.

[0046] The dust-proof member 4 includes multiple groups of dust-proof components 41 arranged on the surface of the sliding plate 22. Each dust-proof component 41 includes two support plates 42 fixedly connected to the outer wall of the sliding plate 22. A dust-proof rod 43 is fixedly connected between the two support plates 42. The dust-proof rod 43 is located at one end of the sliding plate 22 away from the transmitter main body 1. A torsion spring 44 is fixedly connected to the outer wall of the dust-proof rod 43. A dust-proof plate 45 is fixedly connected to the outer wall of the torsion spring 44. The dust-proof plate 45 is located around the dust-proof rod 43 and is rotatably connected to the dust-proof rod 43. A dust-proof cloth 46 is fixedly connected to the outer wall of the dust-proof plate 45.

[0047] Before the transmitting connector 13 is connected to the transmitting interface 11, the dust-proof plate 45 is located at the transmitting interface 11. The dust-proof plate 45 and the dust-proof cloth 46 can effectively prevent dust in the air from entering the interior of the transmitting interface 11 and avoid dust in the air from adhering to the surface of the core wire 12 inside the transmitting interface 11.

[0048] When connecting the transmitting connector 13, the transmitting connector 13 first abuts against the surface of the sliding plate 22. When the transmitting connector 13 pushes the sliding plate 22, the sliding plate 22 squeezes the spring 21, and the transmitting interface 11 slides within the sliding hole 23 opened in the sliding plate 22. When the sliding plate 22 slides to the bottom of the transmitting interface 11, the transmitting connector 13 is connected to the transmitting interface 11. At the same time, when the sliding plate 22 slides, the dust-proof plate 45 abuts against the transmitting interface 11 and rotates around the dust-proof rod 43. At this time, the torsion spring 44 stores energy until the dust-proof rod 43 exposes the core wire 12, so that the core wire 12 contacts the transmitting connector 13. When pulling out the transmitting connector 13, the spring 21 resets, and the spring 21 pushes the sliding plate 22 back. At this time, the torsion spring 44 drives the dust-proof plate 45 to rotate around the dust-proof rod 43 until the dust-proof plate 45 covers the transmitting interface 11, effectively avoiding the accumulation of dust and dirt around the core wire 12 and affecting the contact quality of the core wire 12.

[0049] The cleaning mechanism 3 includes a through groove 31 opened on the outer wall of the transmitting interface 11. Two connecting plates 32 are fixedly connected to one end of the sliding plate 22 close to the transmitter main body 1. The two connecting plates 32 are respectively located on both sides of the transmitting interface 11. The two connecting plates 32 are fixedly connected by a cleaning plate 33. The cleaning plate 33 penetrates through the through groove 31. A cleaning ring 34 is fixedly connected to the center of the cleaning plate 33. The cleaning ring 34 is located outside the core wire 12 and is slidably connected to the core wire 12.

[0050] A rotating groove 35 is opened at one end of the cleaning ring 34 close to the transmitter main body 1. A rotating ring 36 is rotatably connected inside the rotating groove 35. A plurality of cleaning teeth 37 are fixedly connected to one end of the rotating ring 36 close to the transmitter main body 1. A rope 38 is fixedly connected to the outer wall of the rotating ring 36. The rope 38 is wound around the outer periphery of the rotating ring 36. A rope groove 39 is opened on the cleaning plate 33, and the rope 38 penetrates through the rope groove 39.

[0051] When the sliding plate 22 slides outside the transmitting interface 11, the sliding plate 22 drives the cleaning plate 33 to slide through the connecting plates 32. At this time, the cleaning ring 34 at the center of the cleaning plate 33 slides outside the core wire 12. The cleaning teeth 37 inside the cleaning ring 34 can scrape the surface of the core wire 12 when the cleaning ring 34 slides, removing the oxides generated on the surface of the core wire 12 due to long-term non-use and exposure to the air, as well as the corrosion generated on the surface of the core wire 12 due to the influence of moisture, dust and other impurities in the environment, and avoiding poor contact or open circuit between the transmitting connector 13 and the core wire 12.

[0052] A fixed rod 310 is fixedly connected to the outer wall of the transmitter main body 1. A shrapnel 311 is fixedly connected to the outer wall of the fixed rod 310. One end of the shrapnel 311 away from the fixed rod 310 is fixedly connected to a winch 312. The winch 312 is located around the fixed rod 310 and is rotatably connected to the fixed rod 310. One end of the rope 38 away from the rotating ring 36 is fixedly connected to the winch 312. The rope 38 is wound around the periphery of the winch 312.

[0053] When the cleaning plate 33 slides in the direction towards the winch 312, the winch 312 rotates around the fixed rod 310 through the shrapnel 311. At this time, the winch 312 winds the rope 38. The other end of the rope 38 slides in the rope groove 39. At the same time, the rope 38 pulls the rotating ring 36 to rotate in the rotating groove 35. When the rotating ring 36 rotates, it can drive the cleaning teeth 37 to rotate. Since the cleaning teeth 37 are serrated, multiple cleaning teeth 37 are located around the core wire 12 and are arranged in a ring shape. The rotating cleaning teeth 37 can clean the oxides or rust on the surface of the core wire 12, ensuring smooth connection between the transmitting joint 13 and the transmitting interface 11.

[0054] Embodiment 2

[0055] Please refer to Figures 16 - 17 , a detecting member 5 capable of detecting the core wire 12 is provided at one end of the cleaning plate 33 close to the transmitter main body 1. The detecting member 5 includes two conductive rods 51 fixedly connected to one end of the cleaning plate 33 close to the transmitter main body 1. The two conductive rods 51 are respectively located on both sides of the core wire 12 and are in close contact with the core wire 12. A detecting rod 52 is fixedly connected to the lower end of the cleaning plate 33. A sliding groove 53 is fixedly connected to the outer wall of the transmitter main body 1. The end of the detecting rod 52 is located inside the sliding groove 53. A conductive sheet 54 is fixedly connected to the inner wall of the sliding groove 53. A power supply 55 is provided on one side of the transmitting interface 11. An indicator light 56 is provided on the outer wall of the transmitter main body 1. The conductive rods 51, the detecting rod 52, the conductive sheet 54, and the indicator light 56 are respectively connected in series with the power supply 55.

[0056] When the transmitting joint 13 is inserted into and pulled out from the transmitting interface 11, the cleaning plate 33 will slide around the transmitting interface 11. When the cleaning plate 33 drives the detecting rod 52 below to slide, the detecting rod 52 slides in the sliding groove 53. Every time the detecting rod 52 passes by the conductive sheet 54, since the conductive rods 51, the detecting rod 52, the conductive sheet 54, and the indicator light 56 are respectively connected in series with the power supply 55, and the two conductive rods 51 are in close contact with the core wire 12, the indicator light 56 will light up. If impurities such as oxides or rust generated on the surface of the core wire 12 block the contact between the conductive rods 51 and the core wire 12, the indicator light 56 will not light up. By observing the state of the indicator light 56, it can be determined whether there are impurities on the surface of the core wire 12, thereby warning of the failure of the transmitter main body 1.
