[0032] The auxiliary sliding mechanism 15 includes an auxiliary slider 16, a soft iron rod 17 and a scraper plate 18. The auxiliary slider 16 is symmetrically arranged on the upper wall of the arc-shaped slide rail 21 on both sides of the active slider 4. The auxiliary slider 16 is slidably arranged on the outside of the arc-shaped slide rail 21. The soft iron rod 17 penetrates the active slider 4 and is arranged between the auxiliary sliders 16.

[0033] The anti-vibration locking mechanism 27 includes a fixing frame 28 , a fixing seat 29 and a locking opening 20 . The fixing frame 28 is arranged on the upper wall of the active slider 4 , the fixing seat 29 is arranged on the upper wall of the fixing frame 28 , and a plurality of locking openings 20 are arranged on the inner wall of the fixing seat 29 .

[0034] The model of the proximity switch 25 is LP-18N8C.

[0035] When in use, the arc base 1 is installed inside the shooting area of ​​news dissemination, the news dissemination lens is placed on the upper wall of the fixing seat 29, and the news dissemination lens is fixed by passing the bolt through the locking port 20;

[0036] Since the distance of the arc-shaped slide rail 21 is relatively long, the probability of dust and impurities adhering to the arc-shaped slide rail 21 is relatively large. The dust, dirt and other impurities on the arc-shaped slide rail 21 will increase the friction coefficient between the arc-shaped slide rail 21 and the active slider 4, causing the active slider 4 to slide unsmoothly on the arc-shaped slide rail 21, and even produce a jamming phenomenon, which seriously affects the operation smoothness and accuracy of the equipment. In the initial state, the active slider 4 is located in the middle of the soft iron rod 17, and the soft iron rods 17 on both sides of the active slider 4 are the same length. The driving electromagnet 26 is energized to generate magnetism, and the driving electromagnet 26 magnetizes the soft iron rod 17. After magnetization, the soft iron rod 17 has magnetism, and the soft iron rod 17 magnetically adsorbs the fixed iron sleeve 23;

[0037] The driving motor 6 is started, and the driving motor 6 drives the active gear 7 to rotate through the power end, and the active gear 7 is meshed with the arc rack 8, and the active gear 7 rolls along the arc rack 8. The active gear 7 drives the active slider 4 to slide along the upper wall of the arc slide rail 21 through the motor box 5, and the active slider 4 slides along the arc slide rail 21 to change the shooting position and angle, and the cleaning channel 13 is set on the side wall of the arc base 1 between the teeth of the arc rack 8. The blowing pump 11 is started, and the blowing pump 11 blows gas into the arc tube 10 through the exhaust end. The gas in the arc tube 10 enters the diversion channel 12 and then sprays to the area between the teeth of the arc rack 8 through the cleaning channel 13, which can remove impurities that fall between the teeth of the arc rack 8, so as to avoid the active gear 7 from contacting with impurities during the rolling process and affecting the moving stability of the active slider 4, thereby ensuring the shooting efficiency of news dissemination;

[0038] When the active slider 4 slides along the arc slide rail 21, the soft iron rod 17 is driven to move by the fixed iron sleeve 23. There is a certain gap between the side wall of the soft iron rod 17 and the inner wall of the fixed iron sleeve 23, and the two do not contact each other. When the auxiliary slider 16 slides along the arc slide rail 21, the scraper plate 18 is used to remove impurities on its upper wall. The soft iron rod 17 drives the auxiliary slider 16 to move along the upper wall of the arc slide rail 21 following the active slider 4. When the driving electromagnet 26 magnetizes the soft iron rod 17, the magnetic field strength of the end of the soft iron rod 17 away from the driving electromagnet 26 is weak, and the magnetic field strength of the end of the soft iron rod 17 close to the driving electromagnet 26 is strong, so that the active slider 4 uses the strong magnetic field between the fixed iron sleeve 23 and the soft iron rod 17 to push the auxiliary slider 16. The auxiliary slider 16 removes impurities on the arc slide rail 21 through the scraper plate 18, reducing the probability of the active slider 4 contacting with impurities on the upper wall of the arc slide rail 21, and ensuring the smooth movement of the active slider 4.

[0039] When the impurities on the upper wall of the arc-shaped slide rail 21 adhere strongly, the auxiliary slide block 16 stops sliding due to the obstruction of the impurities, and the active slide block 4 continues to slide along the upper wall of the arc-shaped slide rail 21 under the rolling of the active gear 7. At this time, the lengths of the soft iron rods 17 on both sides of the active slide block 4 are different, and the length of the soft iron rod 17 in the moving direction of the active slide block 4 is shorter;

[0040] The proximity switch 25 is started, and the proximity switch 25 senses the auxiliary slider 16. The limit electromagnet 22 and the driving electromagnet 26 are arranged opposite to each other. The limit electromagnet 22 is energized to generate magnetism. The limit electromagnet 22 and the driving electromagnet 26 are arranged with the same pole. The driving electromagnet 26 is fixed on the active slider 4 and pushes the limit electromagnet 22 by repulsion. Under the combined action of the suction force of the fixed iron sleeve 23 on the soft iron rod 17 and the repulsion of the driving electromagnet 26 on the limit electromagnet 22, on the one hand, the collision between the active slider 4 and the auxiliary slider 16 is avoided. On the other hand, the stubborn impurities on the upper wall of the arc-shaped slide rail 21 can be removed, thereby improving the support efficiency of the news communication shooting equipment. The above operation can be repeated when it is used next time.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0042] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
