Description

Technical Field

[0001] The utility model relates to the field of monitoring devices, in particular to a landslide ground deformation monitoring device using the InSAR technology. Background Art

[0002] The reasons for the rapid development of InSAR technology can be attributed to two aspects: one is the need for regional surface deformation disaster monitoring and forecasting; the other is a continuous and reliable data source. Global topographic mapping, earthquakes, ground subsidence, landslides, volcanic movement, glacial activity and other surface deformation monitoring are common application areas of InSAR technology, especially geological disaster monitoring.

[0003] The prior art discloses a publication number of CN211826499U, which discloses a landslide monitoring device based on InSAR, including a drive box, an interferometric radar, a support seat, a moving mechanism and a support block. The top of the drive box is connected to the bottom of the interferometric radar, the bottom of the drive box is fixedly connected to the top of the support seat, the support seat is connected to the moving mechanism, and the side of the bottom of the support seat is welded to the top of the support block. When there is no need to move, the roller can be raised and separated from the ground to prevent damage to the roller caused by long-term support. It has the advantage of being able to move the interferometric radar without the help of tools. However, the prior art is only placed on the ground by support blocks and anti-slip pads. The equipment is not fixed firmly enough and is prone to displacement, which is not conducive to use. Utility Model Content

In addition, the setting of the lifting device facilitates the adjustment of the height of the monitoring device body and the micro antenna.

[0016] 2. The utility model rotates the electric shaft through the motor, the driving gear will rotate with the shaft, and the driven gear will rotate under the driving wheel; and because the top of the lead screw a is rigidly connected to the base, and the base is restricted by the auxiliary telescopic rod and cannot rotate, the lead screw a can move up and down under the action of the driven gear, thereby adjusting the height of the monitoring device body and the micro antenna;

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] What needs to be explained in detail in the present embodiment is that the fixing device includes a fixing plate 13 located on the lower side of the support plate 8, and two screw sleeves 11 symmetrically distributed on the left and right are installed on the upper end of the fixing plate 13, and a screw b10 connected to the bottom of the support plate 8 at the top is installed inside the screw sleeve 11, and a ground plug 14 is provided at the bottom of the fixing plate 13; by rotating the screw b10, the length of the screw b10 inserted into the screw sleeve 11 can be realized, thereby adjusting the height of the ground plug 14 from the ground.

[0032] It should be noted that the utility model is a landslide ground deformation monitoring device using InSAR technology, and the monitoring device body 3, micro-antenna 4, solar panel 5, motor and primary spur gear reducer and other components are all universal standard parts or components known to those skilled in the art, and the structure and principle thereof can be known to those skilled in the art through technical manuals or conventional experimental methods;

[0033] Please refer to Figure 2-3 Based on the landslide ground deformation monitoring device using InSAR technology provided in the first embodiment of the present application, the second embodiment of the present application proposes another landslide ground deformation monitoring device using InSAR technology. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0034] Specifically, the difference of the landslide ground deformation monitoring device using InSAR technology provided in the second embodiment of the present application is that the base 1 includes an upper shell 101 and a lower shell 102; the upper shell 101 is slidingly connected to the lower shell 102, and a shock absorbing mechanism 2 is provided between the upper shell 101 and the lower shell 102.

The sealing strip 205 can seal the gap between the plug sleeve 201 and the plug rod 202 to prevent the damping grease 204 from leaking from the plug sleeve 201.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
