Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to an assembled microwave reflection device and a microwave radar testing device. Background Art

[0002] Microwave radar technology primarily utilizes the properties of electromagnetic waves, emitting microwaves and receiving their reflected waves to measure parameters such as the distance, speed, and position of target objects. This technology has demonstrated its unique value in numerous applications, such as monitoring the health of bridge structures and high-rise buildings. A detailed introduction is as follows:

[0003] Basic Principle: Microwave radar transmits microwave signals and receives their reflected signals, analyzing the time delay and frequency variations of these reflected signals to acquire target information. Microwave radar has the ability to penetrate clouds and fog, allowing it to operate normally in adverse weather conditions.

[0004] Application scenarios: In bridge or high-rise building projects, microwave radar is used to monitor the deformation and vibration of objects to ensure the safety and stability of bridges or high-rise buildings.

[0005] To achieve high-precision multi-target ranging, corner reflectors require the placement of specific reflective targets on the structures being monitored to enhance the strength of the reflected signal. Corner reflectors are a type of radar reflector that reflects radar signals in the same direction as the incident direction, resulting in extremely high reflectivity.

[0006] To achieve high-precision multi-target ranging, it is necessary to place specific reflective targets on the structures to be monitored to enhance the strength of the reflected signal. Corner reflectors are a type of radar reflector that can reflect radar signals in the same direction as the incident direction, and they have extremely high reflectivity.

[0007] The existing corner reflectors are large in size and very inconvenient to transport and install, which brings certain troubles to the test. Utility Model Content

[0009] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an assembled microwave reflection device, comprising:

[0010] The mounting base can be detachably connected to the structure to be monitored; and

[0011] The reflector has a tower-like structure, comprising a plurality of reflective layers, wherein the plurality of reflective layers are stacked sequentially from bottom to top, gradually reduced in size, and disassembled to form the tower-like reflector. Each reflective layer comprises three reflective plates, which are circumferentially arranged and sequentially connected to form the reflective layer. The inner surface of each reflective plate is a reflective surface, and the three reflective surfaces of a single reflective layer are perpendicular to each other.

[0012] The connecting piece is arranged on the outer surface of the reflecting plate and is used to connect two adjacent reflecting plates.

[0013] Furthermore, each of the reflective surfaces is covered with a protective film.

[0014] Furthermore, the connecting member includes a mounting plate, a connecting plate fixed on the mounting plate and a bolt assembly. The mounting plate is fixed on the outer surface of the reflective plate, and the connecting plates of two adjacent reflective plates are connected by the bolt assembly.

[0015] Furthermore, a rubber gasket is provided between two upper and lower adjacent connecting plates.

[0016] Furthermore, the mounting seat is a universal connection seat.

[0017] A microwave radar testing device comprises a radar and the above-mentioned assembled microwave reflecting device, wherein the reflector can absorb the microwave signal emitted by the radar and reflect it back to the radar.

[0018] Furthermore, the radar is connected to the structure to be monitored via the mounting base.

[0019] Beneficial effects of the utility model:

[0020] The above-mentioned assembled microwave reflector and microwave radar test device include an assembled microwave reflector and a microwave radar test device. The assembled microwave reflector includes a mounting base, a reflector, and a reflector. The mounting base can be detachably connected to the structure to be monitored.

[0034] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0035] See Figures 1 to 5 The utility model provides an assembled microwave reflection device, including a mounting seat 100 and a reflector 200.

[0036] See Figures 1 to 4 Specifically, the mounting base 100 can be detachably connected to the structure to be monitored. Here, the structure to be monitored is typically a bridge, an aircraft, or the like. When in use, the mounting base 100 is simply mounted on the surface of the monitored structure. The mounting base 100 can be a universal joint as known in the art.

[0037] Reflector 200 has a tower-like structure and includes multiple reflective layers 210. These layers 210 are stacked sequentially from bottom to top, gradually decreasing in size and disassembled to form a tower-like reflector 200. Each reflective layer 210 includes three reflective plates 211. The three reflective plates 211 are arranged circumferentially and joined together to form the reflective layer 210. The inner surfaces of the reflective plates 211 are reflective surfaces, and the three reflective surfaces of a single reflective layer 210 are perpendicular to each other.

[0038] When in use, multiple reflection layers 210 are stacked in sequence from bottom to top and connected through the connecting piece 300. Since the three reflection surfaces of a single reflection layer 210 are perpendicular to each other, three equal and mutually perpendicular isosceles triangle large reflection surfaces can be formed. The three perpendicular large reflection surfaces form a double mirror principle, which can reflect the radar 400 signal incident at any angle back to the radar 400 according to the incident path.

[0039] The connecting member 300 is disposed on the outer surface of the reflecting plate 211 and is used to connect two upper and lower adjacent reflecting plates 211 to form a tower-shaped reflector 200 .

[0040] By using the assembled microwave radar 400 corner reflector, the entire reflective device is assembled, and each reflective layer 210 is small in size. The connected reflective layers 210 can be disassembled and packaged for transportation or storage, which is convenient for storage and transportation.

[0041] In practice, the length a of the three edges of reflector 200 can be set to 15cm-50cm. The specific operation method is to select the specifications and dimensions of the corner reflector based on the test distance to ensure that the echo signal energy meets the test accuracy requirements. The following table can be used to select the recommended values for the length a of the three edges of reflector 200 and the measurement distance:

[0042] Serial number Test distance R(m) Corner reflector size a(cm) 1 R≤10 15 2 10<R≤20 20 3 20<R≤50 25 4 50＜R≤100 35 5 100＜R≤200 50

[0043] In this embodiment, the connector 300 includes a mounting plate 310, a connecting plate 320 fixed to the mounting plate 310, and a bolt assembly. The mounting plate 310 is fixed to the outer surface of the reflective plate 211. The connecting plates 320 of two adjacent reflective plates 211 are connected by the bolt assembly, thereby connecting the separated reflective layers 210 together to form the reflector 200.

[0044] In a specific implementation, a rubber gasket may be provided between two upper and lower adjacent connecting plates 320 to further improve the connection firmness of the two connecting members 300 .

[0045] In addition, during specific implementation, each reflecting surface can be covered with a detachable protective film. When not being tested, the protective film covers the reflecting surface and can be removed when in use.

[0046] Please refer to the figure. The present invention also provides a microwave radar testing device. The microwave radar testing device includes a radar 400 and the above-mentioned assembled microwave reflecting device. The reflector 200 can absorb the microwave signal emitted by the radar 400 and reflect it back to the radar 400.

[0047] Furthermore, the radar 400 can be connected to the structure to be monitored using the mounting base 100 .

[0048] The microwave radar test device is configured to be spliced together, making it easy to carry and store, thereby greatly improving ease of use.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
