[0005] In order to improve the technical problem that the horizontal monitoring state of the main body of geological disaster warning equipment in the prior art cannot be maintained in a horizontal state during long-term monitoring, the present application provides a disaster warning device.

[0006] This application provides a disaster warning device, which adopts the following technical solution:

[0007] A disaster warning device comprises a disaster warning device body, and also includes a base, a center rod fixedly connected to the base at the lower end, a storage plate rotatably connected to the upper end of the center rod at the lower side, a lower support ring rotatably connected to the base, an upper support ring rotatably connected to the lower side of the storage plate, a side rod threadedly connected to the lower support ring at the lower end, and two oblique rods rotatably connected to the upper ends of the side rods at the lower ends.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] By setting a central rod to directly support the storage plate and the main body of the disaster warning device, by vertically setting a side rod threadedly connected to the lower support ring, and rotating the two ends of the inclined rod connected to the storage plate at the upper end of the side rod, together with the central rod, a three-point support for the storage plate is formed to ensure stable support for the main body of the disaster warning device. In the process of installation and adjustment, the support height of the inclined rod can be changed by rotating the side rod, and the indirect support position of the inclined rod to the storage plate can be adjusted by simultaneously rotating the side rod, the upper support ring and the lower support ring, so as to adjust the inclination angle of the storage plate, thereby improving the technical problem that the main body of the geological disaster warning device in the prior art cannot maintain a horizontal state during long-term monitoring.

[0018] The following is combined with Figure 1-5 This application is described in further detail.

[0019] The embodiment of the present application discloses a disaster warning device.

[0020] Reference Figures 1 to 3 A disaster warning device includes a disaster warning device body 1, a base 2, a center rod 3 fixedly connected to the base 2 at the lower end, a storage plate 4 rotatably connected to the upper end of the center rod 3 at the lower side, a lower support ring 5 rotatably connected to the base 2, an upper support ring 6 rotatably connected to the lower side of the storage plate 4, a side rod 7 threadedly connected to the lower support ring 5 at the lower end, and two oblique rods 8 rotatably connected to the upper ends of the side rods 7 at the lower ends. The disaster warning device body 1 is fixed on the storage plate 4 and is located directly above the center rod 3. The lower support ring 5 and the upper support ring 6 are both rotatably installed with the center rod 3 as the central axis. The two oblique rods 8 are both inclined and the upper ends are both rotatably connected to the upper support ring 6.

[0021] When adjusting and making the disaster warning device body 1 maintain a horizontal installation state, the support height of the two oblique rods 8 to the upper support ring 6 can be changed by rotating the side rod 7, so that the end of the storage plate 4 is tilted with the center rod 3 as the center. At the same time, the storage plate 4 can be fixed by hand to keep the storage plate 4 and the disaster warning device body 1 still, and the lower support ring 5, the upper support ring 6, the side rod 7 and the two oblique rods 8 can be rotated at the same time to change the support point position of the two oblique rods 8 indirectly to the storage plate 4 through the upper support ring 6, thereby forming a horizontal support effect on the disaster warning device body 1, thereby improving the technical problem in the prior art that the horizontal monitoring state of the geological disaster warning device body 1 cannot be maintained in a horizontal state during long-term monitoring.

[0022] Through the above-mentioned installation method, during the installation process, it is not necessary to completely ensure the vertical installation of the base 2. The horizontal installation of the disaster warning device body 1 can be achieved by the vertical movement of the side rod 7 and the rotation of the diagonal rod 8.

[0023] When the landslide moves for secondary monitoring, there is no need to remove and reinstall the base 2. The main body 1 of the disaster warning device can be horizontally installed again by vertically moving the side rod 7 and rotating the inclined rod 8, which is convenient to use.

[0024] The disaster warning device body 1 can be a slope stability detection radar, GNSS surface displacement, inclination accelerometer, multi-parameter crack meter, rain gauge, soil moisture meter, mud level meter, warning horn, etc. When it is installed horizontally, the center of gravity is located on the vertical axis of the center rod 3. The disaster warning device body 1 can be installed with the storage plate 4 through a protective cover or other methods (such as bolts).

[0025] The base 2 includes a bottom plate 21 and a plurality of conical positioning tubes 22 fixedly connected to the bottom plate 21, so as to be fixed to the ground through the conical positioning tubes 22 to ensure the installation stability of the base 2. The lower end of the central rod 3 is fixedly connected to the bottom plate 21 of the base 2.

[0026] A lower annular groove 211 is formed on the bottom plate 21 with the center rod 3 as the center axis.

[0027] Reference Figures 2 to 5 An upper ring groove 41 is provided on the lower side of the storage plate 4 , and the upper ring groove 41 is a card groove. The upper support ring 6 is adapted and rotatably connected to the upper ring groove 41 , so that the upper support ring 6 can be rotatably installed through the upper ring groove 41 .

[0028] The upper annular groove 41 is arranged with the central rod 3 as the central axis, and its cross section may be dovetail-shaped or stepped to ensure that the upper supporting ring 6 will not separate from the storage plate 4 .

[0029] Reference Figure 1 , Figure 2The lower support ring 5 includes a lower ring plate 51 and a plurality of support rods 52 evenly distributed and fixedly connected to the lower ring plate 51 at the upper ends. The lower ends of the support rods 52 are rotatably connected to the base 2, and the lower ends of the side rods 7 are threadedly connected to the lower ring plate 51. The lower ring plate 51 supports the side rods 7, and the support rods 52 can be rotated during the process of adjusting the circumferential position of the side rods 7.

[0030] The plurality of support rods 52 may be two, three, four, five, six, etc., and the lower ends thereof are adapted and rotatably connected to the lower annular groove 211, so as to realize the rotatable installation of the support rod 52 through the lower annular groove 211. In the embodiment of the present application, the cross section of the lower annular groove 211 is dovetail-shaped or stepped to prevent the support rod 52 from falling out of the lower annular groove 211 during the rotation process.

[0031] Reference Figures 2 to 5 The side rod 7 includes a threaded rod 71 whose lower end is threadedly connected to the lower support ring 5 and a mounting rod 72 whose lower end is rotatably connected to the upper end of the threaded rod 71 . The lower ends of the two oblique rods 8 are both rotatably connected to the mounting rod 72 .

[0032] By rotating the threaded rod 71 , the inclined rod 8 can be moved vertically. During this process, the threaded rod 71 rotates relative to the mounting rod 72 .

[0033] As a specific rotation method, the threaded rod 71 and the mounting rod 72 are coaxially connected for rotation, and a rotation block 711 is formed at the upper end of the threaded rod 71, and a rotation groove adapted for rotation of the rotation block 711 is opened at the lower end of the mounting rod 72. The vertical section of the rotation block 711 is an inverted isosceles trapezoid to prevent the rotation block 711 from falling out of the rotation groove, thereby ensuring the rotation connection state of the threaded rod 71 and the mounting rod 72.

[0034] The threaded rod 71 of the side rod 7 is away from the central rod 3 relative to each support rod 52, so that the outer side of each support rod 52 forms a space for the side rod 7 to move circumferentially, which is convenient for applying force to the side rod 7 and causing it to rotate.

[0035] The oblique rod 8 includes a rod sleeve 81 and two connecting rods 82. The two oblique rods 8 have external threads with opposite rotation directions and are respectively threadedly connected to the two ends of the rod sleeve 81. The other end of one oblique rod 8 is rotatably connected to the mounting rod 72 of the side rod 7, and the other end of the other oblique rod 8 is rotatably connected to the upper support ring 6.

[0036] During the adjustment process, the length of the inclined rod 8 can be adjusted by rotating the rod sleeve 81, so that the lengths of the two inclined rods 8 can adapt to the change, so as to maintain the horizontal state of the disaster warning device body 1 under the joint action of the center rod 3.

[0037] The internal threaded hole of the rod sleeve 81 is a stepped hole, and the inner diameter of the openings at both ends is smaller than the inner diameter of the middle end. The ends of the two connecting rods 82 threadedly connected to the rod sleeve 81 are both in a "T" shape, and a limit is formed by abutting against the shoulders to prevent the rod sleeve 81 and the connecting rod 82 from detaching during the process of rotating the rod sleeve 81 to extend the inclined rod 8.

[0038] Reference Figures 1 to 4 The upper end of the central rod 3 and the upper ends of the two oblique rods 8 are both provided with hinged parts 9, and the hinged parts 9 include hinged seats 91 and steel balls 92 rotatably connected to the hinged seats 91, one of the hinged seats 91 is fixed to the storage plate 4, and the upper end of the central rod 3 is fixedly connected to one of the steel balls 92, the other hinged seats 91 are all fixed to the upper support ring 6, and the upper ends of the oblique rods 8 are respectively fixedly connected to the other two steel balls 92.

[0039] There are two other hinged seats 91 to respectively connect with the two inclined rods 8 .

[0040] During use, the central rod 3 and the oblique rod 8 can indirectly rotate relative to the storage plate 4 through the rotation of the steel ball 92 relative to the hinge seat 91 .

[0041] Through the connection of three hinges 9, the central rod 3 and the two oblique rods 8 form a three-point support for the placement board 4 to ensure the horizontal and stable installation of the placement board 4 and the disaster warning device body 1 fixed on the placement board 4.

[0042] During the adjustment process, the storage plate 4 and the disaster warning device body 1 fixed on the storage plate 4 rotate relative to the steel ball 92 fixed to the center rod 3 at the same time, and the inclined rod 8 can rotate relative to the storage plate 4 through the steel ball 92 during the extension and retraction process, so that the angle between the two inclined rods 8 changes, causing the storage plate 4 to tilt.

[0043] It should be noted that, in the process of rotating the rod sleeve 81 of the inclined rod 8, the connecting rod 82 fixed to the steel ball 92 can be fixed, and then the rod sleeve 81 can be rotated.

[0044] The hinge seat 91 includes a fixed plate fixedly connected to the storage plate 4 or the upper support ring 6, two hinge plates arranged opposite to each other, and fasteners for fixing the two hinge plates, wherein one hinge plate is fixedly connected to the fixed plate, and the other hinge plate is slidably connected to the fixed plate, and the two hinge plates have rotation grooves facing each other at one end away from the fixed plate, and the steel ball 92 is adapted and rotationally connected to the two rotation grooves. Specifically, the steel ball 92 rotates in the two rotation grooves 714 that are opened opposite to each other.

[0045] Among them, the fasteners can be bolts.

[0046] A card slot is provided on the fixed plate, and the card slot runs through one side of the fixed plate. One end of the other hinged plate is adapted and slidably connected to the card slot, so that the other hinged plate can be limited and slid through the card slot, so that the two facing rotating grooves can be separated by sliding the other hinged plate, thereby removing the steel ball.

[0047] The clamping groove may be a stepped groove or a dovetail groove to prevent the hinged plate from being separated from the fixed plate along the thickness direction of the fixed plate.

[0048] The lower ends of the two oblique rods 8 are rotatably connected to a rotating seat 73 fixedly connected to the side rod 7, and the lower end of the connecting rod 82 below is rotatably connected to the rotating seat 73. The rotating seat 73 includes two clamping plates, both ends of which are rotatably connected to the rotating shafts of the two clamping plates, and the connecting rod 82 is rotatably connected to the rotating shaft, so that the oblique rod 8 can be rotatably installed relative to the side rod 7 through the rotating seat 73.

[0049] 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.
