Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] see Figure 1-6 , the present invention provides a technical solution: a three-port combined antenna for high-speed rail, including an antenna body 1, the bottom surface of the antenna body 1 is fixedly connected with a fixing seat 2, and a fixing mechanism 3 is installed inside the fixing seat 2, and on the fixing seat 2 Anti-collision mechanisms 4 are installed on the left and right sides of the surface, and a stabilizing mechanism 5 is installed on t...

The invention discloses a three-port combined antenna for high-speed rails, and relates to the technical field of high-speed rail antennas. The antenna includes an antenna body; the bottom of the antenna body is fixedly connected to a fixing seat; a fixing mechanism is installed at the internal of the fixing seat; anti-collision mechanisms are installed on the left and right sides on the upper surface of fixing seat; and a stable mechanism is installed at the bottom of the fixing seat. Through the arrangement of buffering plates, flying birds or birds can be prevented from bumping against theantenna body; as a high-speed rail cannot help bumping against the birds during moving with high speed, the reduction sensitivity and transmission speed of the antenna body can be caused if the birdsbump against the antenna body, and the buffering plates can prevent the birds from bumping against the antenna body; and through the arrangement of the stable mechanism, stability can be increased when the fixing seat is placed, the adaptation of the weight of the antenna can be realized so that the fixing seat cannot shake, and influences on the antenna body cannot be caused through the wind flowgenerated during the high-speed moving of the high-speed rail.
Description
technical field [0001] The invention relates to the technical field of high-speed rail antennas, in particular to a three-port combined antenna for high-speed rail. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, more and more types of rail transit have emerged, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. [0003] At present, the high-speed rail needs to use a three-port combination antenna during driving. The combination antenna is a terminal for positioning or navigation by receiving satellite signals, and the antenna must be used to receive signals. The existing high-speed rail uses a three-port combination antenna, often in Wh...
