Description

Technical Field

[0001] This invention belongs to the field of slope protection brick technology, specifically a self-recovering benchmark. Background Technology

[0002] Traditional signposts often employ a fixed structure, which is prone to permanent bending or breakage under external forces, leading to malfunction of the warning function and high replacement costs. Existing elastic reset structures often rely on a single spring or hinge, resulting in low reset accuracy and uneven stress that can cause bolts to loosen. Furthermore, nighttime warnings depend on passive reflective materials, lacking active light sources to indicate the risk of tipping over. In addition, electronic monitoring modules are typically externally mounted, with complex wiring that is susceptible to water and soil erosion, and are difficult to integrate with mechanical reset mechanisms. Therefore, a novel self-resetting signpost is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: Insufficient stability of the reset structure: Traditional elastic components are prone to skew and wear, exposed bolts are prone to corrosion, and the reset trajectory is uncontrollable; Lack of tilt monitoring and warning: There is a lack of real-time detection of the tilting state of the sign post, and the passive reflective sleeve cannot actively alarm at night.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a self-recovering benchmark, including a base assembly, the base assembly including a rubber buffer pad and a mounting plate, wherein the mounting plate is provided on the upper side of the rubber buffer pad;

[0006] The recovery structure includes a second mounting plate and elastic elements. The second mounting plate is connected to the first mounting plate through four elastic elements.

[0011] The second mounting plate has several movable grooves. The inner diameter of the movable grooves is larger than the diameter of the long connecting bolt but smaller than the maximum diameter of the long connecting bolt, so that the second mounting plate can swing and move.

[0012] As a preferred technical solution for the self-recovering marker, the recovery marker assembly further includes LED lights, support strips, and protruding holes.

[0035] The mounting plate 201 has several movable grooves.

[0038] It also includes a collapsing mechanism 400, which includes an electrical control box 401, located above the first mounting plate 102 and below the second mounting plate 201.

[0039] The overturning mechanism 400 also includes an assembly plate 402, a proximity switch 403, a connecting post 404, a loading plate 405, a circuit board 406, and a lithium battery 407. The inside of the control box 401 has a receiving cavity. Four connecting posts 404 are provided at the top of the receiving cavity. The loading plate 405 is connected to the connecting posts 404 by bolts. The circuit board 406 and the lithium battery 407 are provided on the loading plate 405. Four proximity switches 403 are provided on the control box 401. An assembly plate 402 is provided at each of the four corners of the top of the receiving cavity.

[0040] The circuit board 406 is equipped with a power module, a control module, and a detection module;

[0041] The power module includes a lithium battery 407, a battery management chip, a voltage regulator, a filter capacitor, and a battery connector. The lithium battery 407 is an 18650 lithium-ion battery. The battery management chip is a TP4056, which manages the charging of the lithium battery 407, preventing overcharging, over-discharging, and short circuits. It charges via a Micro-USB or Type-C interface and outputs 3.7V. The voltage regulator is an AMS1117-3.3LDO regulator, which converts the 3.7V from the lithium battery 407 to a stable 3.3V to power the circuit board 406.

[0042] It can also be paired with the LM2596, i.e., DC-DC step-down module; protection diode, model: 1N4007, function: to prevent reverse battery connection and protect the circuit;

[0043] The filter capacitor is a 100μF electrolytic capacitor. Its function is to stabilize the power output and reduce voltage fluctuations.

[0044] The battery connector is a JST PH 2.0mm 2-pin connector, used to connect the lithium battery 407 to the circuit board 406 for easy disassembly. The control module includes a microcontroller, an Arduino Nano ATmega328P, which reads the signal from the proximity switch 403 and controls the LED 304 to light up. It operates at 3.3V / 5V, has digital I / O pins, and is easy to program. A pull-up resistor, a 10kΩ resistor in a 0805 package, is used to ensure stable signal pin levels for the proximity switch 403. The detection module includes the proximity switch 403 (model LJ12A3-4-Z / BX), and the LED 304 is electrically connected to the circuit board 406 using a long wire.

[0045] The specific implementation method is as follows: When the sign post 302 is impacted and tilts or falls, the mounting plate 201 also tilts. The movement of the mounting plate 201 is detected by the proximity switch 403 and indicated by the illumination of the alarm light. There are 4 proximity switches 403 to accommodate the sign post 302 tilting in any direction. When any one of the proximity switches 403 senses the sign post 302 tilting, it immediately sends a signal to indicate that the sign post 302 has tilted and indicates this by the illumination of the light on the sign post 302. The indicator light of the sign post 302 is also connected to the control box through the wiring hole at the top of the control box 401. After the compression of the sign post 302 ends, the spring 203 compresses the mounting plate 201 from four directions, so that the mounting plate 201 returns to its original balanced state and remains horizontal, thereby causing the sign post 302 to return to a vertical posture.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
