Description

Technical Field

[0001] This utility model relates to the field of microwave transmission technology, and in particular to a non-line-of-sight microwave transmission device. Background Technology

[0002] Non-line-of-sight (NLS) microwave transmission is a wireless communication technology that allows microwave signals to be transmitted even when there are obstacles between the transmitter and receiver. Unlike line-of-sight (LAS) transmission, which requires a straight-line propagation between two points without obstructions, NLS uses mechanisms such as reflection, diffraction, and scattering to allow signals to bypass obstacles and reach their destination. This transmission method is particularly suitable for urban environments or areas with complex terrain, where direct line-of-sight paths may be blocked by buildings, mountains, or other natural obstacles. NLS equipment is typically lightweight and easy to deploy quickly, playing a vital role in emergency communications, temporary support, and communications in remote areas. The application of this technology expands the use cases of microwave communications and improves the flexibility and robustness of communication networks.

[0003] Among them, the non-line-of-sight digital microwave wireless transmission equipment used to complete non-line-of-sight microwave transmission operates in the 2.4G anti-interference frequency band, with a maximum transmission rate exceeding 150Mbp and a transmission power of 28dBm. It features high receiving sensitivity, wireless low-frequency microwave, and extremely strong diffraction and penetration performance.

[0004] For example, a novel non-line-of-sight microwave device with application number CN202321971030.8 has the following technical features: it includes a fixed plate, a groove is provided on the right surface of the fixed plate, a bidirectional threaded rod is rotatably connected to the inner wall of the fixed plate, and a quick installation device is provided inside the fixed plate. The quick installation device includes a slider, which is threaded onto the outer surface of the bidirectional threaded rod, and a semi-circular ring is fixedly connected to the front surface of the slider.

[0005] The above solution allows the microwave device to be installed on a utility pole using a quick installation device. The microwave device is a microwave signal transmitter. In reality, the antenna and the microwave signal transmitter need to be connected via a cable. To ensure the spacing between the antenna and the microwave signal transmitter, the cable usually needs to be quite long. However, if the spacing between the antenna and the microwave signal transmitter is too small, the cable will become too long and droop. This can lead to the cable becoming stuck in the air and touching or detaching itself.

[0006] Therefore, a non-line-of-sight microwave transmission device is proposed to solve or alleviate the above problems. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-line-of-sight microwave transmission device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A non-line-of-sight microwave transmission device includes a column, an upper beamline assembly mounted on the column, and a lower beamline assembly located below it. The upper and lower beamline assemblies are adjustable in orientation along the length of the column. Each of the upper and lower beamline assemblies has several horizontally arranged support columns, and the support columns on the upper or lower beamline assembly are movable horizontally around the outer ring of the support columns.

[0010] Preferably, both the upper and lower wire harness assemblies include an annular frame that can be fitted onto the outer ring of the column and whose inner diameter can be adjusted, and a plurality of sliding rings that are slidably connected to the annular frame, wherein the support column is fixedly connected to the outer end face of the sliding rings.

[0011] Preferably, the outer ring of the support column is uniformly fitted with a plurality of rubber rings.

[0012] Preferably, the end of the support column furthest from the slip ring is configured as a ball head.

[0013] Preferably, the annular frame is arc-shaped, and connecting plates are fixedly connected to both ends of the annular frame. A through hole is provided on the connecting plate, and a tightening bolt is inserted into the through hole. The tightening bolt is threaded with a nut that clamps the two connecting plates, and two force-applying plates are fixedly connected to the outer ring of the screw head of the tightening bolt.

[0014] Preferably, the system also includes a base, and a connecting panel is fixedly connected to the lower end of the column. Several reinforcing plates are fixedly connected between the connecting panel and the lower outer ring of the column, and the connecting panel is fixedly connected to the top surface of the base.

[0015] Preferably, it also includes an antenna, which is fixedly connected to the upper end of the column.

[0016] Preferably, it also includes a microwave signal transmitting host, which is coupled to the antenna via a cable. A hose clamp is fitted around the outer ring of the column, and a connecting seat is fixedly connected to the hose clamp. A vertical hinge seat is fixedly connected to the end of the connecting seat away from the column. A horizontal hinge seat is hinged inside the vertical hinge seat. A mounting seat is detachably connected to the back of the microwave signal transmitting host, and the mounting seat is rotatably connected to the horizontal hinge seat.

[0017] This utility model has the following beneficial effects:

[0018] In actual installation, the antenna is mounted on the upper part of the column, then the hose clamp is fitted onto the outer ring of the column, and then the microwave signal transmitter is mounted on the mounting base. This allows the microwave signal transmitter to complete the installation. The microwave signal transmitter can swing left and right via the mounting base and the horizontal hinge. If up and down swing is required, it is achieved through the connection between the horizontal and vertical hinges. The antenna and the microwave signal transmitter are then connected via a cable. If the distance between the antenna and the microwave signal transmitter is too small, resulting in an excessively long cable, this will cause the problem. If this situation occurs, then before connecting the cable to the antenna and the microwave signal transmitter, the cable needs to be passed sequentially through the support posts in the upper and lower cable assemblies, and wound back and forth. When the cable contacts the support posts in the upper and lower cable assemblies, it should be made to contact them through the rubber ring, thus preventing the cable from easily detaching from the upper and lower cable assemblies. Finally, ensure that the cable is slightly longer than the distance to the microwave signal transmitter when it leaves the upper and lower cable assemblies. This way, the cable length can be appropriately shortened, avoiding the problem of the cable being too long and getting touched and detached in mid-air. Attached Figure Description

[0030] A non-line-of-sight microwave transmission device, such as Figure 1 and Figure 2As shown, it includes a column, an upper wire assembly 12 mounted on the column, a lower wire assembly 13 located below it, a base 1, an antenna 5, and a microwave signal transmitting host 11.

[0031] like Figure 1 and Figure 2 As shown, a connecting panel 3 is fixedly connected to the lower end of the column 2. Several reinforcing plates 4 are fixedly connected between the connecting panel 3 and the lower outer ring of the column 2. The connecting panel 3 is fixedly connected to the top surface of the base 1. The antenna 5 is fixedly connected to the upper end of the column 2. The microwave signal transmitter 11 and the antenna 5 are coupled by a cable. A hose clamp 6 is fitted around the outer ring of the column 2. A connecting seat 7 is fixedly connected to the hose clamp 6. A vertical hinge seat 8 is fixedly connected to the end of the connecting seat 7 away from the column 2. A horizontal hinge seat 9 is hinged inside the vertical hinge seat 8. A mounting seat 10 is detachably connected to the back of the microwave signal transmitter 11. The mounting seat 10 is rotatably connected inside the horizontal hinge seat 9.

[0032] like Figure 3 As shown, the upper wire harness assembly 12 and the lower wire harness assembly 13 can be adjusted in position along the length of the column. Both the upper wire harness assembly 12 and the lower wire harness assembly 13 have several horizontally arranged support columns 19, and the support columns 19 on either the upper or lower wire harness assembly 12 can be displaced horizontally around their outer rings. Specifically, both the upper wire harness assembly 12 and the lower wire harness assembly 13 include an annular frame 14 that can be fitted onto the outer ring of the column 2 and has an adjustable inner diameter, and several slip rings 18 that are slidably connected to the annular frame 14. The support column 19 is fixedly connected to the outer end face of the slip ring 18. Several rubber rings 21 are evenly fitted on the outer ring of the support column 19. The end of the support column 19 away from the slip ring 18 is set as a ball head 20. The annular frame 14 is arc-shaped, and the two ends of the annular frame 14 are fixedly connected to connecting pieces 15. The connecting pieces 15 have through holes, and tightening bolts 16 are inserted in the through holes. The tightening bolts 16 are threaded with nuts that clamp the two connecting pieces 15. The outer ring of the screw head of the tightening bolts 16 is fixedly connected to two centrally symmetrical force-applying pieces 17.

[0033] This invention simplifies the installation process of the microwave signal transmitter 11. In actual operation, the antenna 5 is first fixed to the top of the column to ensure its stable position. Then, the outer perimeter of the column is fixed using a hose clamp 6 to increase the stability of the overall structure. Next, the microwave signal transmitter 11 is securely placed on the specially designed mounting base 10. This step is the key to completing the entire installation. In order to enable the microwave signal transmitter 11 to flexibly adjust its direction, this invention includes a horizontal hinge base 9, which allows the microwave signal transmitter 11 to rotate left and right to adapt to different signal transmission requirements. If vertical adjustment is required, it is achieved through the ingenious connection between the horizontal hinge base 9 and the vertical hinge base 8.

[0034] When connecting antenna 5 to microwave signal transmitting host 11, a cable is used as the transmission medium. However, if the distance between antenna 5 and host is too close, the cable may be too long, affecting aesthetics and safety. To solve this problem, before connection, the cable needs to be passed through the support post 19 in the upper cable tie assembly 12 and lower cable tie assembly 13 and properly wound. This design not only helps manage the cable, but also enhances the cable's stability through the contact between the rubber ring 21 and the support post 19, preventing the cable from accidentally falling off.

[0035] Finally, ensure that the cable is slightly longer than the distance directly connected to the microwave signal transmitter 11 when it leaves the cable bundle assembly. This is to prevent the cable from being too long and dangling, reducing the risk of it coming loose due to contact. In this way, the present invention not only improves the ease of installation, but also enhances the stability and reliability of the system, enabling it to maintain good working condition in various environments.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
