Description

Technical Field

[0001] The present application relates to the technical field of mountain landslide monitoring, and in particular to a deformation monitoring device for geological disasters in mountainous areas. Background Art

[0002] INSAR (Interferometric Synthetic Aperture Radar) is a space-based earth observation technology that combines traditional SAR (Synthetic Aperture Radar) remote sensing technology with radio astronomy interferometry. INSAR obtains SAR complex image pairs of the same target area by emitting microwaves to the target area and receiving the echo reflected by the target. When there is a coherence condition between the complex image pairs, the interference pattern can be obtained by conjugate multiplication of the SAR complex image pairs. According to the phase value of the interference pattern, the path difference of the microwaves in the two images can be calculated, thereby obtaining the topography, landforms and slight changes on the surface of the target area. Therefore, INSAR can be applied to geological disasters and early warning of geological disasters in complex mountainous areas.

[0003] During the installation process, it is necessary to ensure that the pitch angle of the INSAR corner reflector meets the satellite's orbital shooting parameter requirements, and the pitch angle needs to be determined based on the specific satellite orbit parameters and the design specifications of the corner reflector. The satellite's orbital parameters may vary depending on factors such as satellite type, mission requirements, and earth gravity. However, most traditional INSAR reflectors are fixed to the ground with cement blocks, which makes it difficult to make corresponding adjustments during the installation process to meet the pitch angle design requirements. Utility Model Content

[0005] The present application provides a deformation monitoring device for geological disasters in mountainous areas, which adopts the following technical solutions:

[0006] A deformation monitoring device for geological disasters in mountainous areas includes a corner reflector, a base, a main support rod with a lower end fixedly connected to the base, a support plate rotatably connected to the main support rod, and at least three auxiliary support rods, each of the auxiliary support rods is circumferentially evenly distributed on the main support rod, and the lower end of the auxiliary support rod is slidably connected to the middle end of the main support rod, and the upper end is rotatably connected to the support plate, the lower end of the auxiliary support rod is threadedly connected to a limit nut abutting against the main support rod, and the corner reflector is fixedly connected to the support plate.

[0007] By adopting the above technical solution, during installation, the limit nut can be unscrewed to make the lower ends of different auxiliary support rods slide with different strokes relative to the main support rod, thereby driving the support plate and the corner reflector to undergo adaptive angle changes, thereby improving the problem of difficulty in adjusting the installation angle of existing corner reflectors during installation.

[0008] In summary, this application includes the following beneficial technical effects:

[0009] The corner reflector is supported by setting a main support rod and a support plate, so that the corner reflector is supported at a certain height, and under the auxiliary support of at least three auxiliary support rods uniformly distributed on the main support rod in the circumferential direction, the corner reflector is ensured to be stably supported, and the upper ends of the main support rod and the auxiliary support rod are both rotatably connected to the support plate, and the lower end of the auxiliary support rod is slidably connected to the main support rod and threadedly connected with a limiting nut, so that under the action of twisting the limiting nut, the auxiliary support rod can slide relative to the main support rod, thereby changing the supported angle of the corner reflector, so as to improve the problem that the existing corner reflector is difficult to adjust the installation angle during the installation process;

[0010] The U-shaped clip can rotate relative to the fixed rod, and the shaft rod can rotate relative to the U-shaped clip at the same time, and the two rotation axes are perpendicular to each other, so that the horizontal position and opening direction of the sliding hole on the shaft rod for the auxiliary support rod can be changed to adaptively adjust the supporting angle of the extension rod to the auxiliary support rod;

[0019] The following is combined with Figure 1-6 This application is described in further detail.

[0020] The embodiment of the present application discloses a device for monitoring deformation of geological disasters in mountainous areas.

[0021] Reference Figures 1 to 5 A deformation monitoring device for geological disasters in mountainous areas includes a corner reflector 1, a base 2, a main support rod 3 with a lower end fixedly connected to the base 2, a support plate 4 rotatably connected to the main support rod 3, and at least three auxiliary support rods 5. Each auxiliary support rod 5 is evenly distributed on the main support rod 3 in the circumferential direction, and the lower end of the auxiliary support rod 5 is slidably connected to the middle end of the main support rod 3, and the upper end is rotatably connected to the support plate 4. The lower end of the auxiliary support rod 5 is threadedly connected to a limiting nut 51 abutting against the main support rod 3, and the corner reflector 1 is fixedly connected to the support plate 4.

[0022] During installation, the limit nut 51 can be unscrewed to allow the lower ends of different auxiliary support rods 5 to slide with different strokes relative to the main support rod 3, thereby driving the support plate 4 and the corner reflector 1 to undergo adaptive angle changes, thereby improving the problem of difficulty in adjusting the installation angle of the existing corner reflector 1 during installation.

[0023] Among them, the base 2 can be made by pouring a concrete base on site, and the lower end of the main support rod 3 is prefabricated in the base 2; the base 2 can also be a steel frame structure welded by steel bars, steel plates, etc.

[0024] The number of auxiliary support rods 5 can be three, four, five or six, etc. In the figure, only three of the multiple auxiliary support rods 5 are shown.

[0025] In the embodiment of the present application, the main support rod 3 is supported on the vertical line of the center of gravity of the corner reflector 1 through the support plate 4 to relatively maintain the stability of the corner reflector 1 when being supported.

[0026] The horizontal distance between the upper end of the auxiliary support rod 5 connected to the support plate 4 and the main support rod 3 is greater than the horizontal distance between the lower end and the main support rod 3, so that multiple triangular support structures are formed through multiple auxiliary support rods 5 to ensure that the corner reflector 1 is stably supported.

[0027] Reference Figures 2 to 6 The middle end of the main support rod 3 is fixedly connected to a plurality of extension rods 6, the number of the plurality of extension rods 6 is equal to the number of the auxiliary support rods 5, and they are arranged one by one, and the lower end of the auxiliary support rod 5 is slidably connected to the end of the extension rod 6 away from the main support rod 3. At this time, the limit nut 51 abuts against the cantilever end of the extension rod 6.

[0028] By setting the extension rod 6, the horizontal distance from the lower end of the auxiliary support rod 5 to the main support rod 3 is extended, so that the auxiliary support rod 5 is staggered from the main support rod 3, ensuring the stability of the support and facilitating the adjustment of the support length of the auxiliary support rod 5.

[0029] In an embodiment of the present application, the extension rod 6 includes a fixed rod 61 having one end fixedly connected to the main support rod 3 and a support seat 62 coaxially rotatably connected to the other end of the fixed rod 61. The support seat 62 extends horizontally relative to the rotation axis of the fixed rod 61, and the auxiliary support rod 5 is slidably connected to the support seat 62.

[0030] During the installation process, the support seat 62 can be rotated relative to the fixed rod 61 to change the direction of the sliding hole 6221 on the support seat 62 for the auxiliary support rod 5 to slide, thereby achieving a smooth sliding connection between the auxiliary support rod 5 and the support seat 62.

[0031] Based on the above embodiment, the support seat 62 includes a U-shaped clamp 621 whose closed end is rotatably connected to the other end of the fixed rod 61 and an axle rod 622 whose two ends are rotatably connected to the open end of the U-shaped clamp 621. A sliding hole 6221 is provided at the middle end of the axle rod 622, and the auxiliary support rod 5 passes through the sliding hole 6221, and the auxiliary support rod 5 is slidably connected to the sliding hole 6221 of the axle rod 622.

[0032] In the process of sliding each auxiliary support rod 5 to adjust the angle of the corner reflector 1, the sliding hole 6221 is used to realize the sliding connection between the shaft rod 622 and the auxiliary support rod 5, and when sliding the auxiliary support rod 5 to adjust the support angle of the corner reflector 1, the shaft rod 622 is used to adaptively rotate relative to the U-shaped clamp 621.

[0033] The two ends of the shaft rod 622 can be rotatably connected to the two arms of the open end of the U-shaped clip 621 through bearings (not shown in the figure).

[0034] Reference Figure 6 On the basis of the above embodiment, a stepped hole 6211 is provided at the closed end of the U-shaped clip 621, and the other end of the fixing rod 61 is in a "T" shape and is rotatably connected to the stepped hole 6211 to achieve a state of mutual engagement between the two, thereby preventing the U-shaped clip 621 from detaching from the fixing rod 61.

[0035] The depth of the stepped hole 6211 is greater than the length of the “T”-shaped end of the fixing rod 61 , so as to enable the U-shaped clip 621 to slide in the length direction of the fixing rod 61 and adjust the horizontal distance of the sliding hole 6221 relative to the main support rod 3 .

[0036] Reference Figures 3 to 5 On the basis of the above embodiment, both upper and lower sides of the shaft rod 622 are provided with limit nuts 51 threadedly connected to the auxiliary support rod 5, and the limit nuts 51 are specifically abutted against the upper and lower sides of the shaft rod 622. The sliding limit of the auxiliary support rod 5 is realized by a plurality of limit nuts 51.

[0037] When adjusting and installing the corner reflector 1, the multiple limit nuts 51 can be unscrewed first to move them away from the shaft rod 622, so that the auxiliary support rod 5 can slide relative to the shaft rod 622, and during the sliding of the auxiliary support rod 5, the shaft rod 622 can rotate relative to the U-shaped clamp 621. At the same time, the U-shaped clamp 621 rotates and slides relative to the fixed rod 61 to adaptively adjust the opening direction of the sliding hole 6221.

[0038] A washer 52 is provided between the shaft rod 622 and each limiting nut 51 . The washer 52 is sleeved on the auxiliary support rod 5 , so as to form a buffering and isolating effect through the washer 52 , thereby reducing the probability of the limiting nut 51 becoming loose.

[0039] Reference Figures 2 to 5 The upper ends of the main support rod 3 and each auxiliary support rod 5 are provided with a hinge 7, and the hinge 7 includes a hinge seat 71 fixedly connected to the support plate 4 and a steel ball 72 rotatably connected to the hinge seat 71. The upper end of the main support rod 3 is fixedly connected to one of the steel balls 72, and the upper ends of each auxiliary support rod 5 are fixedly connected to the other steel balls 72 one by one.

[0040] The hinge seat 71 includes a fixed plate 711 fixedly connected to the support plate 4, two hinge plates 712 arranged opposite to each other, and a fastener 713 fixing the two hinge plates 712, wherein one hinge plate 712 is fixedly connected to the fixed plate 711, and the other hinge plate 712 is slidably connected to the fixed plate 711, and the two hinge plates 712 have rotating grooves 714 facing each other at one end away from the fixed plate 711, and the steel balls 72 are adapted and rotatably connected to the two rotating grooves 714.

[0041] During the process of adjusting the angle of the corner reflector 1, the auxiliary support rod 5 and the steel ball 72 simultaneously rotate relative to the hinge seat 71. Specifically, the steel ball 72 rotates in two rotating grooves 714 that are open toward each other.

[0042] The fastener 713 may be a bolt.

[0043] A slot 7111 is provided on the fixed plate 711, and the slot 7111 runs through one side of the fixed plate 711. One end of the other hinged plate 712 is adapted and slidably connected to the slot 7111, so that the other hinged plate 712 can be limited and slid by the slot 7111, so that the two opposing rotating grooves 714 can be separated by sliding the other hinged plate 712, thereby removing the steel ball 72.

[0044] The locking groove 7111 may be a stepped groove or a dovetail groove to prevent the hinge plate 712 from being separated from the fixing plate 711 along the thickness direction of the fixing plate 711 .

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
