[0034] Please refer to Figures 1 to 4 , the present invention provides a portable microwave reflection device, including a universal joint seat 100, a reflector 200 and a connecting piece 300.

[0035] Specifically, the universal joint seat 100 can be detachably connected to the building structure to be monitored. Here, the building structure to be monitored is generally a bridge or a high-rise building. During use, the universal joint seat 100 can be installed on the surface of the monitored building structure.

[0036] Please refer to Figure 2 , the reflector 200 includes three reflecting plates 210. One of the reflecting plates 210 is connected to the universal joint seat 100; the reflecting plate 210 has a reflecting surface. The three reflecting plates 210 can be detachably spliced together to form the reflector 200, and the three reflecting surfaces are arranged facing each other and perpendicular to each other. Connecting pieces 300 are fixed on the outer walls of the three reflecting plates 200, and the three reflecting plates 200 are spliced together through the connecting pieces 300. The connection between the reflecting plates 200 can be a bolt connection or a snap connection.

[0037] Please refer to Figure 4 , during use, the three perpendicular reflecting surfaces are spliced together. The three perpendicular reflecting surfaces form the principle of a corner cube, and can reflect the radar 400 signal incident at any angle back to the radar 400 along the incident route.

[0038] With the above-mentioned portable microwave radar 400 corner reflector, the whole reflector is small in volume, convenient for storage and transportation. At the same time, since the three reflecting plates 210 are connected in a spliced manner, when transporting or storing, the connected reflecting plates 210 can be disassembled and packaged for transportation or storage, which is further convenient for transportation and can prevent sharp corners from hurting people. After arriving at the site, by connecting the connecting pieces 300 to each other, the splicing of the reflector 200 can be completed.

[0039] Please refer to Figure 2, As a preferred embodiment, the reflector 210 is an isosceles right triangle, and the two right sides of three isosceles right triangles are spliced with each other. This shape can reduce the number of sharp corners of the entire reflector, and at the same time, the reflection effect can be the best.

[0040] In specific implementation, the length of the straight side of the isosceles right triangle can be 15 cm - 50 cm.

[0041] As a preferred embodiment, the connector 300 is spherical petal-shaped. In specific implementation, the spherical petal-shaped connector 300 can be arranged near the edges and sharp corners of the reflector 100, which can not only play a connecting role but also prevent the sharp corners from hurting people.

[0042] Please refer to Figure 3 , In this embodiment, the universal joint base 100 includes a first mounting plate 110, a second mounting plate 120, a third mounting plate 130, and a connecting ear 140.

The second mounting plate 120 is located between the first mounting plate 110 and the third mounting plate 130. Four pairwise opposite connecting ears 140 are provided on the third mounting plate 130. Two of the connecting ears 140 are respectively hinged to the two connecting ears 140 on the first mounting plate 110 through the connecting hole 150, and the remaining two connecting ears 140 are respectively hinged to the two connecting ears 140 on the third mounting plate 130 through the connecting hole 150, and the reflector 210 is connected to the first mounting plate 110.

[0043] During use, first install the third mounting plate 130 on the monitored building structure, then install the reflector 200 on the first mounting plate 110, then loosen the connection between the connecting ears 140, and then adjust the angles of the first mounting plate 110 and the second mounting plate 120 according to the position of the radar 400 so that one of the reflecting surfaces can receive the signal emitted by the radar 400.

[0044] In this embodiment, the connecting hole 150 includes a first circular through hole 151 and a first arc-shaped through slot 152, and the central axis of the first arc-shaped through slot 152 is collinear with the central axis of the first circular through hole 151.

[0045] Adopting this method, when two connecting ears 140 are connected, the two connecting ears 140 are arranged staggeredly, that is: the first circular through hole 151 on one connecting ear 140 is aligned with the first arc-shaped through slot 152 on the other connecting ear 140, and a connecting bolt is inserted in the middle. After adjusting the angle, the bolt can be locked.

[0046] As another preferred embodiment, the first mounting plate 110 is provided with a second circular through hole and a second arc-shaped through slot, and the reflector 210 is connected to the first mounting plate 110 through the second circular through hole and the second arc-shaped through slot. In this way, it is further convenient to connect the reflector 210 to the first mounting plate 110.

[0047] In addition, during specific implementation, a detachable protective film can be covered on each reflecting surface. When not in detection, the protective film covers the reflecting surface, and when in use, it can be removed.

[0048] Please refer to Figure 5 , the present invention also provides a microwave radar testing device. This microwave radar 400 testing device includes a radar 400 and the above-mentioned portable microwave reflection device. The reflector 200 can absorb the microwave signal emitted by the radar 400 and reflect it back to the radar 400.

[0049] Furthermore, the radar 400 can be connected to the structure to be monitored by using the above-mentioned universal joint 100.

[0050] By using the above-mentioned microwave radar testing device, the whole device is convenient to carry and store, greatly improving the convenience of use.
