Description

Technical Field

[0001] This utility model belongs to the technical field of geological disaster early warning equipment, and in particular relates to a geological disaster early warning device. Background Technology

[0002] In the field of geological disaster monitoring and early warning (such as landslides, debris flows, and collapses), monitoring poles are core components that support critical sensors such as GNSS receivers, inclinometers, and rain gauges. The accuracy of monitoring data is highly dependent on the long-term stability of the poles after installation.

[0003] Currently, the common installation method is to directly cast the base of the column into a concrete foundation, or to connect it to pre-embedded parts embedded in the ground through exposed flanges, bolts, and other connecting components. Since the connecting structures (such as bolts and nuts) between the column and the pre-embedded parts are mostly completely exposed to the external environment, they are not only prone to corrosion, but also susceptible to seizing in harsh environments such as mudslides and sandstorms, increasing the difficulty of later disassembly and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a geological disaster early warning device that protects the connecting structure to facilitate later disassembly and maintenance.

[0005] The geological disaster early warning device includes a tubular column with a pre-embedded component embedded in the ground at the lower end. The column and the pre-embedded component are detachably connected by a connecting assembly. A geological monitoring and early warning system is installed on the column. The pre-embedded component is a pre-embedded cylinder. The connecting assembly includes a connecting column, a first fixing sleeve passing through the column, and a connecting column independently passing through the first fixing sleeve. The upper end of the connecting column passes through the first fixing sleeve and is connected to a rotating seat. The rotating seat is in contact with the upper end of the first fixing sleeve. A driving assembly for driving the rotating seat to rotate is installed inside the column. A second fixing sleeve passes through the pre-embedded cylinder. The lower end of the connecting column independently passes through the second fixing sleeve and has an external thread. A threaded collar that is threadedly engaged with the external thread is fitted onto the lower end of the connecting column. The threaded collar abuts against the lower end of the second fixing sleeve. A limiting component is provided between the threaded collar and the inner wall of the pre-embedded cylinder to restrict the rotation of the threaded collar. The upper end of the column has a closed structure.

[0006] The rotating seat is driven by the drive assembly, which in turn drives the connecting column to rotate. The lower end of the connecting column is threadedly engaged with the threaded collar. The rotation of the connecting column causes the threaded collar to move upward and finally abut against the lower end of the second fixed sleeve. The upper end of the connecting column is restricted by the rotating seat to the upper end of the first fixed sleeve, thus completing the connection between the embedded cylinder and the column. The components of the connecting assembly are placed inside the column and the embedded cylinder to provide protection against corrosion and damage from the external environment, facilitating disassembly and maintenance later.

[0007] Furthermore, the drive assembly includes a driven bevel gear, which is mounted on a rotating seat. The centerline of the driven bevel gear is on the same straight line as the centerline of the connecting column. An active bevel gear that meshes with the driven bevel gear is provided on the inner side wall of the column. An internally and externally communicating mounting hole is provided on the side wall of the column. A connector is independently installed in the mounting hole, and one end of the connector is fixed to the active bevel gear.

[0008] The connector is a four-corner or hex-corner connector, which can be used to drive the rotation of a hex or four-corner wrench, thereby driving the drive bevel gear to rotate. The mechanical meshing between the drive bevel gear and the driven bevel gear drives the driven bevel gear to rotate, which in turn drives the rotating seat to rotate.

[0009] Furthermore, a blocking element is fixed inside the column to restrict the upward movement of the driven bevel gear.

[0010] The blocking component includes a fixed plate, which is fixed to the inner wall of the column. A limit bar is fixed to the bottom of the fixed plate, and the lower end of the limit bar abuts against the center of the driven bevel gear, thereby restricting the upward movement of the driven bevel gear and causing it to disengage from the driving bevel gear.

[0011] Furthermore, a spring is installed between the threaded collar and the inner bottom of the embedded cylinder to push the threaded collar upward.

[0012] The spring pushes the threaded collar upward, causing the threaded collar to actively approach the lower end of the connecting post. Then, the rotation of the connecting post causes the external thread to engage with the internal thread inside the threaded collar.

[0013] Furthermore, the limiting component includes two limiting blocks, which are symmetrically distributed on the outer side wall of the threaded collar, and the inner side wall of the embedded cylinder is provided with a sliding groove for the limiting blocks to slide up and down.

[0014] The limiting block and the sliding groove work together to allow the threaded collar to move up and down but not rotate, preventing the threaded collar from rotating under the action of friction when the connecting column rotates, thus failing to achieve the purpose of connection.

[0015] Furthermore, an anchor plate is fixed to the bottom of the pre-embedded cylinder.

[0016] Anchor plates increase the stability of the pre-embedded cylinder when it is embedded underground.

[0017] Furthermore, the upper end of the pre-embedded cylinder is fitted with a top plate, and the lower end of the column is fitted with a bottom plate, with the bottom plate and the top plate fitting together.

[0018] The top plate fits snugly against the bottom plate, increasing the contact area between the column and the embedded cylinder, thus improving the stability of the column when standing vertically.

[0019] Furthermore, the top of the top plate is fixed with several positioning posts distributed along its circumference, and the bottom of the base plate is provided with positioning holes for the positioning posts to pass through.

[0020] The positioning post is inserted into the positioning hole to constrain the rotation of the column.

[0021] Furthermore, the upper end of the column is sealed with a cap.

[0022] The cap seals the top of the column to prevent rainwater, insects, and other debris from entering.

[0023] Compared with the prior art, the present invention has the following beneficial effects: This utility model avoids damage or jamming caused by harsh external environments by placing connecting components, such as connecting columns, threaded collars, and rotating seats, inside the column and embedded cylinder, thus facilitating later disassembly and maintenance.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0026] Example This embodiment describes a geological disaster early warning device, such as... Figures 1 to 3 As shown, it includes a tubular column 1 with a closed upper end, which is sealed by a cap 20 to prevent rainwater and debris from entering.

[0027] The lower end of column 1 is equipped with an embedded part, namely an embedded cylinder 8, which is pre-embedded vertically in the underground foundation pit during construction and then filled with concrete. Anchor plates 9 are fixed to the bottom of the embedded cylinder 8 to enhance its pull-out resistance and stability in the concrete. A top plate 12 is fitted onto the upper end of the embedded cylinder 8, and a base plate 13 is fitted onto the lower end of column 1. The base plate 13 and the top plate 12 are fitted together. The base plate 13 and the top plate 12 are welded to the embedded cylinder 8 and the column 1, respectively. The fit between the top plates 12 and the embedded cylinder 8 increases the contact surface between the column 1 and the embedded cylinder 8, which can effectively improve the stability of the column 1 when it is vertically fixed.

[0028] The top of the top plate 12 is fixed with several positioning posts 6 distributed along its circumference, and the bottom of the base plate 13 is provided with positioning holes for the positioning posts 6 to pass through. In this embodiment, there are four positioning posts 6, which are inserted into the four positioning holes respectively to restrict the rotation of the column 1.

[0029] The column 1 and the embedded parts are detachably connected via a connecting assembly. A geological monitoring and early warning system is installed on the column 1. The system includes a protective box 17, which is mounted on the column 1. A bracket 18 is fixed on the column 1, and a photovoltaic panel 19, a GNSS displacement monitoring module, an inclination sensor, and a rain gauge are installed on the bracket 18 for real-time collection of geological deformation and environmental data. A battery is installed inside the protective box 17, and the photovoltaic panel 19 provides power to the battery, which provides continuous energy to the system. The protective box 17 also integrates a communication and control unit, including a main controller and a wireless communication module, which is responsible for data processing and data interaction with a remote monitoring center.

[0030] The connecting assembly includes a connecting post 5, a first fixing sleeve 14 is installed inside the post 1, the connecting post 5 is independently installed inside the first fixing sleeve 14, the upper end of the connecting post 5 passes through the first fixing sleeve 14 and is connected to a rotating seat 4, the rotating seat 4 is in contact with the upper end of the first fixing sleeve 14, and a driving assembly for driving the rotating seat 4 to rotate is provided inside the post 1; a second fixing sleeve 11 is installed inside the embedded cylinder 8, the lower end of the connecting post 5 independently passes through the second fixing sleeve 11 and has an external thread, and a threaded collar 7 that is threadedly engaged with the external thread is fitted onto the lower end of the connecting post 5, the threaded collar 7 abuts against the lower end of the second fixing sleeve 11; a limiting member is provided between the threaded collar 7 and the inner wall of the embedded cylinder 8 to restrict the rotation of the threaded collar 7.

[0031] The second fixing sleeve 11 is welded and fixed inside the embedded cylinder 8, and the first fixing sleeve 14 is welded and fixed inside the column 1.

[0032] Since the rotating seat 4 will rub against the first fixed sleeve 14 when it rotates, the first fixed sleeve 14 is made of a friction-resistant material. Alternatively, a friction-resistant washer can be provided between the first fixed sleeve 14 and the rotating seat 4.

[0033] The drive assembly includes a driven bevel gear 3, which is mounted on a rotating seat 4. The center line of the driven bevel gear 3 is on the same straight line as the center line of the connecting column 5. An active bevel gear 16 that meshes with the driven bevel gear 3 is provided on the inner side wall of the column 1. An internal and external communicating mounting hole is provided on the side wall of the column 1. A connector 15 is independently installed in the mounting hole, and one end of the connector 15 is fixed to the active bevel gear 16.

[0034] The driven bevel gear 3 is fixed above the rotating seat 4, and its center line coincides with the center line of the connecting column 5. The driving bevel gear 16 is rotatably mounted on the inner wall of the column 1 through the connector 15. The connector 15 is inserted into the mounting hole and can rotate freely. The outer end of the connector 15 has an internal hexagon blind hole. The end of the internal hexagon wrench is inserted into the internal hexagon blind hole to drive the connector 15 to rotate, thereby driving the driving bevel gear 16 to rotate.

[0035] In addition, the drive component can also be a motor, with the motor installed inside the column 1 to drive the rotating seat 4 to rotate. However, since the motor is easily damaged, it also increases the weight of the column 1 and increases the production cost. Therefore, the above solution is preferred.

[0036] A blocking member 2 is fixed inside the column 1 to restrict the upward movement of the driven bevel gear 3. The blocking member 2 includes a fixed plate, which is fixed to the inner side wall of the column 1. A limit bar is fixed to the bottom of the fixed plate. The limit bar abuts against the center of the driven bevel gear 3, effectively preventing it from moving upward axially and ensuring the stability of the meshing.

[0037] The limiting component includes two limiting blocks, which are symmetrically distributed on the outer side wall of the threaded collar 7. The inner side wall of the embedded cylinder 8 is provided with a sliding groove for the limiting blocks to slide up and down. The limiting blocks are embedded in the sliding groove, so that the threaded collar 7 can only slide up and down along the axial direction of the embedded cylinder 8, and cannot rotate.

[0038] A spring 10 is installed between the threaded collar 7 and the inner bottom of the embedded cylinder 8 to push the threaded collar 7 upward. The spring 10 provides a continuous upward thrust to the threaded collar 7, causing it to move upward and actively approach the connecting post 5 that enters the embedded cylinder 8. When the connecting post 5 rotates, the external thread and the internal thread of the threaded collar 7 engage with each other, and after connection, the threaded collar 7 moves upward until it abuts against the lower end of the second fixed sleeve 11. During installation, an anti-loosening washer can be installed between the threaded collar 7 and the lower end of the second fixed sleeve 11 to prevent the threaded collar 7 from loosening.

[0039] In actual use: First, the pre-embedded cylinder 8, with the anchor plate 9 and the second fixing sleeve 11 assembled, is placed vertically in the excavated foundation pit, and then concrete is poured to form a stable foundation. Then, the lower end of the connecting column 5 is inserted into the second fixing sleeve 11, and under the push of the spring 10, the internal thread of the threaded collar 7 initially contacts the external thread of the lower end of the connecting column 5; then, the position of the column 1 is rotated and adjusted so that all the positioning columns 6 enter the positioning holes.

[0040] Finally, insert a standard Allen wrench (or other equivalent tool) into the blind hexagonal hole of the connector 15 and rotate the wrench. The connector 15 drives the driving bevel gear 16 to rotate, which in turn drives the driven bevel gear 3 to rotate. The rotation of the driven bevel gear 3 is transmitted to the connecting column 5 through the rotating seat 4, causing the connecting column 5 to begin rotating. Since the threaded collar 7 is restricted from rotating by the limiting block and the sliding groove, when the connecting column 5 rotates, under the action of the threaded pair, the threaded collar 7 is forced to move upward and finally presses tightly against the lower end face of the second fixed sleeve 11. At the same time, the rotating seat 4 at the upper end of the connecting column 5 is firmly pressed against the upper end face of the first fixed sleeve 14. Through the "upward pressure and downward pull" mechanism, the column 1 and the embedded cylinder 8 are tightly connected as a whole.

[0041] During disassembly and maintenance, simply use a wrench to rotate the connector 15 in the opposite direction to reverse the locking process. The threaded collar 7 is driven downward by the thread of the connecting column 5, and the spring 10 is compressed until the connecting column 5 is completely disengaged from the threaded collar 7, releasing the lock. Then, pull the connecting column 5 out of the second fixing sleeve 11 to complete the disassembly of the column 1 and the embedded cylinder 8.

[0042] In summary, by embedding all the connecting and transmission structures within the column 1 and the pre-embedded cylinder 8, the erosion from wind, rain, and sand, as well as physical collisions, are effectively avoided, and the problems of exposed connecting parts being prone to rust and jamming are solved, thus facilitating subsequent disassembly and maintenance.
