Description

Technical Field

[0001] This utility model relates to the field of communication signal enhancement technology, and more specifically, to a tunnel wall-mounted signal reflection enhancement device. Background Technology

[0002] Base stations inside tunnels are typically installed at the entrance or every few hundred meters. When a signal travels in a straight line along the tunnel, it will rapidly attenuate due to distance and absorption by the walls. By using signal reflection enhancement equipment, weak signals from the direction of the base station can be reflected into the depths of the tunnel, thus filling blind spots. This eliminates the need for densely installing base stations inside the tunnel, thereby significantly reducing construction costs.

[0003] A search revealed that Chinese patent CN223039131U discloses a communication signal enhancement reflector based on open-source hardware. The reflector uses a column to drive a rotating shaft to support the back of the reflector. The rotation of the shaft allows the reflector to adjust its pitch angle. An auxiliary electric push rod can move an auxiliary shaft, which in turn moves an auxiliary plate. The pitch angle of the reflector is adjusted by the rotation of the column and the rotating shaft.

[0004] When in use, the aforementioned signal enhancement reflector can directionally converge and disperse signals and increase reflection intensity through the parabolic surface of the reflector, thereby filling the signal blind spots in the tunnel. The base plate is fixed by multiple bolts to achieve vertical ground support for the reflector. However, it is inconvenient to install the reflector at a high place inside the tunnel, such as two or three meters above the tunnel side wall. When the reflector is installed too low, the reflected signal will be blocked by objects such as streetlights, fire hydrants, and drainage pipes, and cannot be effectively transmitted to the terminal, thus limiting its applicability. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tunnel wall-mounted signal reflection enhancement device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel wall-mounted signal reflection enhancement device, comprising a protective frame and a reflector body, wherein the reflector body is located inside the protective frame, and an installation frame is fixedly connected to the rear side of the protective frame. A column is movably arranged inside the installation frame, and a fixing component is provided on the installation frame. The fixing component includes a positive and negative lead screw, two limiting rods, two moving plates, two pressing plates, multiple insert rods, a washer, a handle, and a fixing bolt. Both ends of the positive and negative lead screws are movably connected to the installation frame through bearings. Both ends of the two limiting rods are fixedly connected to the installation frame, and both limiting rods and the positive and negative lead screws pass through the two moving plates. The rear sides of the two moving plates are respectively fixedly connected to the two pressing plates, and one end of each of the multiple insert rods is respectively fixedly connected to the two pressing plates.

[0007] Furthermore, the opposite sides of the two gaskets are respectively fixedly connected to the two insert rods, and the opposite sides of the two gaskets are in contact with the column.

[0008] As can be seen, in the above technical solution, the gasket can improve the stability between the extrusion plate and the column.

[0009] Furthermore, one end of the handle is fixedly connected to the positive and negative lead screws, and the handle is fixed to the mounting frame by fixing bolts.

[0010] As can be seen, in the above technical solution, the handle is fixed to the mounting frame by fixing bolts, thereby preventing the positive and negative lead screws from rotating on their own.

[0011] Furthermore, the column is provided with multiple insertion holes, and the other end of the multiple insertion rods extends into the multiple insertion holes at corresponding positions.

[0012] It can be seen that the above technical solution facilitates the fixing of the column and the mounting frame.

[0013] Furthermore, the reflector body is provided with an adjustment assembly, which includes a side plate, a rotating shaft, a self-locking motor, a U-shaped plate, a hydraulic cylinder, a sliding plate, and a sliding rod. The front side of the side plate is fixedly connected to the reflector body, and the side plate is fixedly sleeved on the rotating shaft.

[0014] Furthermore, the top and bottom ends of the rotating shaft are movably connected to the U-shaped plate via bearings, the self-locking motor is fixedly installed at the bottom end of the U-shaped plate, and the output shaft end of the self-locking motor is fixedly connected to the rotating shaft. The front and rear ends of the hydraulic cylinder are respectively fixedly connected to the protective frame and the U-shaped plate.

[0015] Furthermore, the bottom end of the slide plate is fixedly connected to the U-shaped plate, and the slide plate is movably fitted onto the slide rod, the rear end of the slide rod being fixedly connected to the protective frame.

[0016] As can be seen, in the above technical solution, the U-shaped plate drives the slide plate to slide on the slide bar, restricting the lateral displacement of the U-shaped plate and ensuring that the main body of the reflector always moves in the horizontal direction.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses multiple bolts to directly install the mounting frame on the side wall of the tunnel. When the side wall of the tunnel is uneven, the mounting frame is fitted onto the column. Turning the handle can drive the two extrusion plates and multiple insert rods to move horizontally, and make the multiple insert rods insert into the insertion holes on the column, thereby fixing the column and the mounting frame together. It is simple to operate, convenient to install the reflector body, and has a wide range of applications.

[0019] 2. This utility model uses a self-locking motor to drive the rotating shaft and side plate to rotate, thereby driving the main body of the reflector to rotate. The position of the main body of the reflector can be adjusted according to needs. The main body of the reflector can directionally converge and disperse signals and improve the reflection intensity. The piston rod on the hydraulic cylinder retracts, driving the U-shaped plate and the main body of the reflector to move backward, so that the main body of the reflector is located inside the protective frame. The protective frame protects the main body of the reflector. The structure is simple and easy to use. Attached Figure Description

[0028] Refer to the instruction manual appendix Figure 1-5 The tunnel wall-mounted signal reflection enhancement device of this embodiment includes a protective frame 1 and a reflector body 2, with the reflector body 2 located inside the protective frame 1. A mounting frame 5 is fixedly connected to the rear side of the protective frame 1. A column 4 is movably arranged inside the mounting frame 5. A fixing component 6 is provided on the mounting frame 5. The fixing component 6 includes a positive and negative screw rod 601, two limit rods 602, two moving plates 603, two pressing plates 604, multiple insert rods 605, a gasket 606, a handle 607, and a fixing bolt 608. Both ends of the positive and negative screw rod 601 are movably connected to the mounting frame 5 through bearings. Both ends of the two limit rods 602 are fixedly connected to the mounting frame 5. Both limit rods 602 and the positive and negative screw rod 601 pass through the two moving plates 603. The rear sides of the two moving plates 603 are fixedly connected to the two pressing plates 604 respectively. One end of the multiple insert rods 605 is fixedly connected to the two pressing plates 604 respectively.

[0029] Furthermore, the opposite sides of the two washers 606 are fixedly connected to the two insert rods 605 respectively, and the opposite sides of the two washers 606 are in contact with the column 4. One end of the handle 607 is fixedly connected to the positive and negative threaded rods 601, and the handle 607 is fixed to the mounting frame 5 by fixing bolts 608. The column 4 has multiple insertion holes, and the other ends of the multiple insert rods 605 extend into the multiple insertion holes at the corresponding positions.

[0030] Furthermore, the reflector body 2 is provided with an adjustment assembly 3, which includes a side plate 301, a rotating shaft 302, a self-locking motor 303, a U-shaped plate 304, a hydraulic cylinder 305, a sliding plate 306, and a sliding rod 307. The front side of the side plate 301 is fixedly connected to the reflector body 2, and the side plate 301 is fixedly sleeved on the rotating shaft 302. The top and bottom ends of the rotating shaft 302 are movably connected to the U-shaped plate 304 through bearings. The self-locking motor 303 is fixedly installed at the bottom end of the U-shaped plate 304, and the output shaft end of the self-locking motor 303 is fixedly connected to the rotating shaft 302. The front and rear ends of the hydraulic cylinder 305 are fixedly connected to the protective frame 1 and the U-shaped plate 304, respectively. The bottom end of the sliding plate 306 is fixedly connected to the U-shaped plate 304, and the sliding plate 306 is movably sleeved on the sliding rod 307. The rear end of the sliding rod 307 is fixedly connected to the protective frame 1.

[0031] The system involves activating a self-locking motor 303, which drives the rotating shaft 302 and side plate 301 to rotate, thereby rotating the reflector body 2. The position of the reflector body 2 can be adjusted as needed. The reflector body 2 can directionally converge and disperse signals, and enhance the reflection intensity. When the enhanced reflection signal is not needed, the hydraulic cylinder 305 is activated. The piston rod on the hydraulic cylinder 305 retracts, causing the U-shaped plate 304 and the reflector body 2 to move backward, placing the reflector body 2 within the protective frame 1. Similarly, the self-locking motor 303 rotates the reflector body 2 ninety degrees, and the protective frame 1 protects the reflector body 2. The structure is simple and easy to use. At the same time, the U-shaped plate 304 drives the sliding plate 306 to slide on the sliding rod 307, limiting the lateral displacement of the U-shaped plate 304 and ensuring that the reflector body 2 always moves in the horizontal direction.

[0032] The usage method of this embodiment is as follows:

[0033] When in use, if the tunnel sidewall is flat, a wall-mounted installation can be used. The mounting frame 5 is directly installed on the tunnel sidewall using multiple bolts, allowing the reflector body 2 to be precisely positioned 2-3 meters inside the tunnel. If the tunnel sidewall is uneven, a vertical support installation can be used. The column 4 is installed on the tunnel floor using multiple bolts, and then the mounting frame 5 is fitted onto the column 4. Turning the handle 607 rotates the positive and negative threaded rods 601. Since both moving plates 603 are threadedly connected to the positive and negative threaded rods 601, the two limiting rods 602 restrict the two moving plates. When 603 rotates, the positive and negative lead screws 601 can drive the two moving plates 603 to move towards each other, thereby driving the two pressing plates 604 and multiple insert rods 605 to move horizontally, and causing the multiple insert rods 605 to be inserted into the insertion holes on the column 4, thus fixing the column 4 and the mounting frame 5 together. The gasket 606 can improve the stability between the pressing plate 604 and the column 4. The operation is simple and convenient for installing the reflector body 2, and has a wide range of applications. Finally, the handle 607 is fixed to the mounting frame 5 by the fixing bolts 608, thereby preventing the positive and negative lead screws 601 from rotating.
