Description

Technical Field

[0001] This utility model relates to the field of radar protection structure technology, and more specifically, to a passive radar protection device. Background Technology

[0002] Slope monitoring systems can provide continuous, 24 / 7 monitoring of slopes and are often used at sites of large-scale geological disasters. Using satellites as the transmitter and passive radar as the receiver, and based on high-precision radar technology, the system collects direct wave signals from the satellite and reflected signals from the monitored area. After direct wave synchronization, imaging algorithms are used to acquire scene images, enabling high-precision 3D deformation information inversion and measurement. The passive radar, directly installed within the monitored area, plays a crucial role in the entire monitoring system.

[0003] When installing passive radar, a radar base must first be laid on the ground, then a radar mounting rod is placed on the base, and finally the passive radar is installed on the mounting rod. During long-term use, falling rocks or mudslides from slopes can easily collide with the mounting rod or accumulate at its base, causing the rod to shift or even collapse, affecting the normal operation of the passive radar. Utility Model Content

[0004] The purpose of this utility model is to provide a passive radar protection device, which can conveniently protect the radar mounting pole and prevent it from shifting or collapsing due to the impact of rolling stones or the accumulation of mudslides.

[0005] This utility model is achieved through the following technical solution: a passive radar protection device, comprising:

[0006] A conical protective frame is located outside the radar mounting rod. The conical protective frame includes two semi-conical frame bodies, one end of which is hinged to each other and the other end is detachably connected by a connector.

[0007] A conical protective sleeve, wherein the conical protective sleeve is provided on the outside of the conical protective frame and is detachably connected to the conical protective frame;

[0008] The clamping component includes two clamping seats that are covered on the radar base. Each of the two clamping seats has a semi-circular notch and is located on both sides of the two semi-conical frames. A tensioning component is provided between the two clamping seats.

[0009] The bottom of the semi-conical frame is provided with a semi-annular protrusion, and the bottom surface of the pressing seat is provided with a pressing step for pressing the semi-annular protrusion.

[0010] Furthermore, the connector includes two connecting seats, which are respectively fixed on two semi-conical frames. One of the connecting seats is provided with multiple connecting bolts, and the other connecting seat is provided with threaded holes for the connecting bolts to be inserted.

[0011] Furthermore, the tensioning component includes two tensioning seats, and a double-ended screw is provided between the two tensioning seats, with tensioning nuts provided at both ends of the double-ended screw.

[0012] Furthermore, the conical protective sleeve includes an elastic steel sheet, which covers the conical protective frame. Both ends of the elastic steel sheet are provided with clamping bands, which are clamped between two connecting seats.

[0013] Furthermore, multiple clamping bands are provided at both ends of the elastic steel sheet, and the multiple clamping bands and multiple connecting bolts are distributed sequentially at intervals.

[0014] Furthermore, the bottom outer edge of the clamping seat is provided with a bottom edge for abutting against the side wall of the radar base. The bottom edge includes two side edges and one end edge, and the side edges and the end edge are integrally formed with the clamping seat.

[0015] Furthermore, flexible anti-slip pads are provided on the sides of the two end edges that are directly opposite each other.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The following is for reference Figures 1-4As shown in the figure, and further explained with reference to specific embodiments, this embodiment provides a passive radar protection device. The passive radar protection device includes a conical protective frame 1, a conical protective cylinder 2, and a clamping member 3. The conical protective frame 1 is located outside the radar mounting rod 4. The conical protective frame 1 includes two semi-conical frame bodies 11. One end of the two semi-conical frame bodies 11 is hinged to each other, and the other end is detachably connected through a connector 12. After connection, the bottom of the conical protective frame 1 is placed on the radar base 5, and there is a gap between the top and the radar mounting rod 4. The conical protective sleeve 2 is installed on the outside of the conical protective frame 1 and is detachably connected to the conical protective frame 1; the clamping component 3 includes two clamping seats 31 covered on the radar base 5, each clamping seat 31 having a semi-circular notch 311 and located on both sides of the two semi-conical frames 11 respectively, and a tensioning component 32 is provided between the two clamping seats 31; wherein, the bottom of the semi-conical frame 11 is provided with a semi-annular protrusion 111, and the bottom surface of the clamping seat 31 is provided with a clamping step 312 for clamping the semi-annular protrusion 111.

[0028] The conical protective frame 1 serves as the supporting skeleton of the overall structure, and the conical protective cylinder 2 serves as the outer protective surface, which can block rolling stones and mudslides, thereby preventing the bottom of the radar mounting rod 4 from being impacted or subjected to lateral pressure for a long time; the clamping component 3 can clamp the conical protective frame 1, improve the stability of the conical protective frame 1, and prevent the conical protective frame 1 from pressing against the radar mounting rod 4.

[0029] Reference Figure 1 , Figure 2 As shown, the connector 12 includes two connecting seats 121, which are respectively fixed on two semi-conical frames 11. One connecting seat 121 has multiple connecting bolts 122, and the other connecting seat 121 has threaded holes for the connecting bolts 122 to be inserted. The two semi-conical frames 11 are rotated away from each other to facilitate fitting onto the outside of the radar mounting rod 4. After fitting, the two semi-conical frames 11 are rotated towards each other and connected together by the connecting bolts 122, giving the overall structure high stability.

[0030] Reference Figure 2 , Figure 3As shown, the conical protective sleeve 2 includes an elastic steel sheet 21, which covers the conical protective frame 1. Multiple clamping bands 22 are provided at both ends of the elastic steel sheet 21, and these bands 22 are clamped between two connecting seats 121. The multiple clamping bands 22 and multiple connecting bolts 122 are distributed sequentially at intervals. Before tightening with the connecting bolts 122, the elastic steel sheet 21 is first covered on the outside of the conical protective frame 1, and the multiple clamping bands 22 at both ends of the elastic steel sheet 21 are clamped between the two connecting seats 121. Then, the connecting bolts 122 are tightened. The connecting bolts 122 connect the two semi-conical frames 11 into one unit while simultaneously clamping the clamping bands 22, thereby ensuring the conical protective sleeve 2 is stably installed on the outside of the conical protective frame 1.

[0031] Reference Figure 1 , Figure 4 As shown, both clamping seats 31 have bottom outer edges with bottom edges 313 for abutting against the side walls of the radar base 5, thereby improving the stability of the clamping seats 31 on the radar base 5. The bottom edge 313 includes two side edges 3131 and one end edge 3132, both of which are integrally formed with the clamping seat 31. (Refer to...) Figure 5 As shown, flexible anti-slip pads 314 are provided on the opposite sides of the two end edges 3132. The flexible anti-slip pads 314 can play an anti-slip role to prevent the clamping seat 31 from becoming loose with the radar base 5 after installation. On the other hand, they can play a buffer role to prevent the clamping seat 31 from being damaged by rigid impact with the radar base 5 during installation.

[0032] Reference Figure 4 , Figure 5 As shown, the tensioning component 32 includes two tensioning seats 321, with a double-ended screw 322 positioned between them. Each end of the double-ended screw 322 has a tensioning nut 323. After both clamping seats 31 are placed on the radar base 5, tightening the tensioning nuts 323 at both ends of the double-ended screw 322 causes the two tensioning seats 321 to move closer together, thus ensuring the clamping seats 31 are stably installed on the radar base 5 without shaking or lateral displacement.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
