Description

Technical Field

[0002] In the field of high - speed rail communication, a reliable and efficient communication system is crucial for ensuring the safe operation of trains and enhancing the passenger experience. The traditional high - speed rail communication method is to set up communication base stations on one side of the high - speed rail track and use omnidirectional antennas for information transmission.

[0003] However, omnidirectional antennas have many drawbacks. Their signal quality is poor, and in the complex high - speed rail operating environment, they are easily interfered with and attenuated, resulting in poor communication stability. At the same time, the propagation distance of omnidirectional antennas is short. In order to ensure good communication coverage throughout the high - speed rail line, a large number of base stations need to be densely set up along the track, which undoubtedly increases the construction cost and maintenance difficulty.

[0004] While directional antennas perform well in terms of signal quality, their fixed propagation direction makes the signal concentrated and has a high gain. However, due to their small coverage area, in the long - distance linear communication scenario of high - speed rail, many additional base stations are also required to meet the communication requirements, which also brings problems of resource waste and cost increase.

[0005] Therefore, there are urgent problems to be solved in the existing high - speed rail communication technology in terms of base station setting and antenna selection, and a new communication solution is urgently needed. Summary of the Invention

Detailed implementation manners

[0034] In order to make the objectives, solutions and advantages of the technical solutions of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present application. Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0035] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0036] As described above, in the use of traditional high-speed rail communication base stations, the signal transmission distance of traditional omnidirectional antennas is short and the signal transmission quality is poor, while the coverage area of directional antennas is small, thus affecting the signal transmission quality and equipment cost of high-speed rail communication base stations.

[0037] To at least partially solve one or more of the above problems and other potential problems, the exemplary embodiments of the present application provide an adjustable antenna bracket for a communication base station tower in high-speed rail construction. The adjustable antenna bracket includes: a cylindrical tower 1 disposed on one side of the railway track, and the distance between the bottom end of the cylindrical tower 1 and the railway track is greater than the height of the cylindrical tower 1; an installation pipe 2 is sleeved on the outer wall of the cylindrical tower 1, and the installation pipe 2 slides along the outer wall of the cylindrical tower 1; a hoisting assembly is provided at the top of the cylindrical tower 1, and the hoisting assembly is connected to the top end of the installation pipe 2; a directional antenna 3 is installed on the outer wall of the installation pipe 2; a rotation driving assembly 4 is provided between the installation pipe 2 and the directional antenna 3, and the installation end of the rotation driving assembly 4 is disposed on the outer wall of the installation pipe 2, and the swinging end installs the directional antenna 3.

[0038] In the above embodiment, the hoisting assembly is composed of a hoisting rope, a pulley block, and an electric wire rewinder. The hoisting rope is towed by the electric wire rewinder, so that the installation pipe 2 is installed by the hoisting rope passing through the pulley block at the top of the cylindrical tower 1. When the directional antenna 3 needs to be repaired, the electric wire rewinder located at the bottom of the cylindrical tower 1 can be controlled to make the installation pipe 2 drive the directional antenna 3 and the rotation driving assembly 4 to slide on the surface of the cylindrical tower 1, and then the inspection can be carried out at the bottom of the tower, improving the maintenance efficiency;

[0039] When the high-speed rail passes by one side of the cylindrical tower 1, the directional antenna 3 is first located on the side where the high-speed rail is approaching. When the high-speed rail drives away from one side of the directional antenna 3, the rotation driving assembly 4 drives the directional antenna 3 to swing around the axis of the cylindrical tower 1, so that when the high-speed rail passes by the cylindrical tower 1, the directional antenna 3 can always face the high-speed rail, thereby improving the signal transmission quality of the high-speed rail communication base station. Since the signal transmission distance of the directional antenna 3 is relatively long, and coupled with the tracking function of the directional antenna 3, the signal transmission distance of the high-speed rail communication base station and the like is further improved, so that the number of high-speed rail communication base stations can be reduced, and the problems of low signal transmission quality, short transmission distance, and unstable signal caused by the use of forward antennas in traditional high-speed rail communication base stations can also be improved.

[0040] Please refer to Figures 1-9 , in some embodiments, a wind power generation assembly 5 is provided at the top of the cylindrical tower 1, and the wind power generation assembly 5 is electrically connected to the rotation driving assembly 4; the wind power generation assembly 5 includes a generator 6 provided at the top of the cylindrical tower 1; further includes a wind wheel 7, and a plurality of the wind wheels 7 are annularly arrayed on the outer wall of the rotor of the generator 6.

[0041] In the above embodiment, a wind power generation assembly 5 is provided at the top of the cylindrical tower 1. Since the height of the cylindrical tower 1 is relatively high, when the wind wheel 7 is driven, the rotation of the wind wheel 7 drives the output shaft of the generator 6 to rotate, so that the generator 6 generates electricity, and then the electricity generated by the generator 6 can be provided to various electrical appliances of the communication base station. Compared with the traditional photovoltaic power generation panel, the wind power generator 6 group can provide stable power, reduce the area required for installation, and reduce the impact of high-altitude wind on the communication base station.

[0042] Please refer to Figures 1-9 , in some embodiments, the rotation driving assembly 4 includes: a swing driving part 8 and an auxiliary driving part 9; there are two groups of the swing driving parts 8, and the two groups of the swing driving parts 8 are vertically spaced and arranged on the outer wall of the installation pipe 2; the swing driving part 8 includes a first toothed ring 10, the first toothed ring 10 is sleeved on the outer wall of the installation pipe 2, the first toothed ring 10 meshes with a first gear 11, the first gear 11 is installed on the output shaft of the driving motor 12, and the driving motor 12 is installed on the outer wall of the installation pipe 2; the driving motor 12 is electrically connected to the generator 6; a swing rod 13 is provided at one end of the first toothed ring 10 away from the driving motor 12; the directional antenna 3 is installed between the swing rods 13 of the two groups of swing driving parts 8, and both ends of the directional antenna 3 are respectively connected to the two swing rods 13.

[0043] In the above embodiment, the rotation driving assembly 4 is composed of the swing driving part 8 and the auxiliary driving part 9, and there are two groups of the driving parts, which are respectively arranged at both ends of the directional antenna 3. When the driving motor 12 of the swing driving part 8 drives the first gear 11 to rotate, the first gear 11 rotates to drive the first toothed ring 10 meshing with it to rotate around the cylindrical tower 1. Since a swing rod 13 is provided on the side of the first toothed ring 10 away from the first gear 11, when the first gear 11 rotates, the swing rod 13 swings around the axis of the cylindrical tower 1, so that the end of the swing rod 13 away from the first toothed ring 10 can drive the directional antenna 3 to swing, thus realizing the purpose of the directional antenna 3 tracking the running high-speed train.

[0044] Please refer to Figures 1-9, in some embodiments, the swing driving part 8 located at the upper part further includes an electric telescopic assembly 14, and the electric telescopic assembly 14 is arranged between the swing rod 13 and the directional antenna 3; one end of the electric telescopic assembly 14 is connected to the end of the swing rod 13 far from the first toothed ring 10, and the telescopic end of the electric telescopic assembly 14 is connected to the directional antenna 3.

[0045] In the above embodiments, the swing driving part 8 further includes an electric telescopic assembly 14. By telescoping the electric telescopic assembly 14, the distance between the top end of the directional antenna 3 and the cylindrical tower 1 can be adjusted, and then the pitching angle of the directional antenna 3 can be changed.

[0046] Please refer to Figures 1-9 , in some embodiments, the auxiliary driving part 9 includes: a first electric telescopic rod 15, the first electric telescopic rod 15 is electrically connected to the generator 6, one end of the first electric telescopic rod 15 is connected to the installation pipe 2, and the other end is connected with a slider 16; the slider 16 is slidably arranged in a first slide rail 17, and one end of the first slide rail 17 is installed on the outer wall of the circumferential surface of the installation pipe 2; a second slide rail 18 is arranged on the surface of the slider 16, the second slide rail 18 is fixedly connected with the slider 16, and the second slide rail 18 is perpendicular to the first slide rail 17; a guide rod 19 is arranged in the second slide rail 18, and the guide rod 19 is slidably arranged in the second slide rail 18; a second gear 20 is rotatably arranged at the end of the guide rod 19 far from the slider 16, the second gear 20 meshes with a second toothed ring 21, and the second toothed ring 21 is concentric with the installation pipe 2; the top end of the guide rod 19 passes through the second gear 20 and is rotatably connected with the swing rod 13.

[0047] In the above embodiments, when the rotation driving part works, the auxiliary driving part 9 is started, the first electric telescopic rod 15 extends and retracts, driving the slider 16 to slide in the first slide rail 17. When the slider 16 slides, since the top surface of the slider 16 is connected to the second slide rail 18, the second slide rail 18 slides along with the slider 16 towards the installation pipe 2. Thus, when the second slide rail 18 moves, the guide rod 19 in the second slide rail 18 is driven to move. When the guide rod 19 moves, the second gear 20 is driven to move. Since the second gear 20 is rotatably connected with the swing rod 13 and the distance between the second gear 20 and the axis of the installation pipe 2 remains unchanged, when the second slide rail 18 moves, the second gear 20 moves along the inner wall of the second toothed ring 21. Through the cooperation of the swing driving part 8 and the auxiliary driving part 9, when one of the swing driving part 8 or the auxiliary driving part 9 fails, driving can still be carried out, and the jitter problem of the directional antenna 3 when swinging around the cylindrical tower 1 can also be reduced.

[0049] In the above embodiment, the radome 22 is used to protect the antenna body 23, avoiding the problems of the exposed antenna body 23 being exposed to the sun and aging, and the attachment of birds, which may cause the service life of the directional antenna 3 to be shortened. The bottom surface of the radome 22 is hinged to the swing rod 13, so that when the first electric telescopic rod 15 expands and contracts, the bottom surface of the radome 22 swings around the swing rod 13, and then the purpose of adjusting the pitch angle of the radome 22 and the antenna body 23 can be achieved.

[0050] Please refer to Figures 1-9 , in some embodiments, two elastic air bags 24 are spaced in the second slide rail 18, and the two elastic air bags 24 are respectively disposed on the inner walls at both ends of the second slide rail 18; the air outlets of the two elastic air bags 24 are both connected to a first air pipe 25; one end of the first air pipe 25 away from the elastic air bag 24 is installed inside the radome 22.

[0051] In the above embodiment, during the swinging process of the directional antenna 3, it needs to reciprocate in the second slide rail 18. When the guide rod 19 moves to one end of the second slide rail 18, the guide rod 19 pushes the elastic air bag 24, so that the elastic air bag 24 is squeezed, and the gas in the elastic air bag 24 is squeezed into the first air pipe 25, so that the exhaust of the elastic air bag 24 can be driven by the reciprocating movement of the directional antenna 3.

[0052] Please refer to Figures 1-9 , in some embodiments, a plurality of arc-shaped conduits 26 are spaced along the length direction inside the radome 22, and both ends of each arc-shaped conduit 26 are respectively communicated with the two first air pipes 25; a plurality of exhaust holes are spaced on one side of the arc-shaped conduit 26 close to the radiation surface of the radome 22.

[0053] In the above embodiment, the air in the first air pipe 25 enters the arc-shaped conduit 26, and then blows towards the radome 22 through the exhaust holes on the surface of the arc-shaped conduit 26, so that the radome 22 can be cleaned of dust by blowing, avoiding the dust on the surface of the radome 22 from clogging the air holes of the radome 22, which may cause the antenna body 23 to be unable to dissipate heat during operation.

[0054] Please refer to Figures 1-9, in some embodiments, the radome 22 includes: a mounting side plate 27, an arc-shaped ventilation plate 28, a bottom plate 29, and a top plate 30; the arc-shaped ventilation plate 28 is disposed on one side of the mounting side plate 27, and the bending direction of the arc-shaped ventilation plate 28 faces the mounting side plate 27. The bottom plate 29 and the top plate 30 are respectively disposed at the lower and upper parts of the mounting side plate 27 and the arc-shaped ventilation plate 28. The mounting side plate 27, the arc-shaped ventilation plate 28, the bottom plate 29, and the top plate 30 form a D-shaped cavity; the arc-shaped conduit 26 is disposed close to the arc-shaped ventilation plate 28, and both ends of each arc-shaped conduit 26 pass through the mounting side plate 27 and are connected to the first air pipe 25; a plurality of drainage grooves 31 are provided on the surface of the bottom plate 29, the drainage grooves 31 penetrate through the bottom plate 29, and a drain pipe 32 is provided below the bottom plate 29.

[0055] In the above embodiments, in winter freezing rain weather, water vapor will enter the radome 22, causing the antenna body 23 to freeze and affecting the normal use of the antenna body 23. Moreover, the water vapor will cause corrosion of the antenna body 23.
