Description

Technical Field

[0001] This utility model relates to a highway slope displacement monitoring and early warning device, belonging to the field of slope safety monitoring technology. Background Technology

[0002] Highway slope landslides are a common geological hazard in mountainous areas. Landslides often occur suddenly, and if vehicles fail to avoid them in time, they can easily cause serious casualties and property damage. Current highway slope monitoring technologies mostly rely on sensors (such as tilt sensors and displacement sensors) combined with data acquisition and analysis systems. However, these systems suffer from high equipment costs, complex installation, and susceptibility to environmental interference (such as wind, rain, and electromagnetic signals), leading to false alarms or missed alarms. Especially in the early stages of a landslide when the displacement is small, existing systems struggle to respond quickly and implement effective road closures, failing to meet the immediate needs of highway safety protection. Therefore, there is an urgent need for a highway slope displacement monitoring and early warning system that is simple in structure, low in cost, fast in response, and highly reliable.

The road closure execution mechanism is connected to the stress circuit breaker mechanism through a circuit breaker detection circuit. The road closure execution mechanism is used to realize road closure and early warning functions.

[0005] Furthermore, the stress-breaking mechanism includes a housing, with multiple wire openings evenly distributed circumferentially on the outer side of the housing. Each wire opening contains a stress-breaking PCB, and a pad island is provided in the middle of the stress-breaking PCB. The pad island is connected to each stress-breaking PCB bridge to make the interior of each wire opening electrically conductive. At least two of the wire openings contain copper wires soldered to the pad islands, and the copper wires pass through the housing and connect to the circuit breaking detection circuit.

[0006] Furthermore, the wire openings are at least four circumferentially distributed on the outside of the housing, and the stress-breaking PCBs are correspondingly arranged in each wire opening. Each stress-breaking PCB is connected to the pad island bridge arranged in the middle, so that the inside of each wire opening is electrically conductive.

[0007] Furthermore, the copper conductor is a 2.5 square millimeter single-core copper conductor.

[0008] Furthermore, the bridge width and bridge length of the stress-breaking PCB are adjusted so that the stress value of the broken PCB bridge is adjusted to 20-25 kg.

[0009] Furthermore, the stress breaking mechanism consists of multiple units connected in series. The arrangement route of the multiple series-connected stress breaking mechanisms is perpendicular to the landslide direction. The multiple series-connected stress breaking mechanisms are laid in the landslide area, and the copper wires at the beginning and end of the multiple series-connected stress breaking mechanisms are connected to the circuit breaking detection circuit, while the middle section is fixed on the slope surface where there is no landslide.

[0010] Furthermore, multiple interconnected stress circuit breaking mechanisms are connected to each other via their respective copper wires to achieve electrical conduction. The multiple interconnected stress circuit breaking mechanisms are positioned at potential sliding surfaces, and the copper wires at the beginning and end are connected to the circuit breaking detection circuit. The middle section is fixed on the stable slopes on both sides of the potential sliding surface, forming a "Z"-shaped monitoring network.

One end of the normally closed contact of the relay is connected to the positive terminal of the power supply, and the other end is connected to one end of the road closure execution mechanism and the other end is connected to the negative terminal of the power supply.

[0012] Furthermore, the road closure execution mechanism includes a barrier gate, and the gate arm includes a support frame and a gate arm. The support frame is set on the side of the road, and the lower end of the gate arm is rotatably connected to the support frame through a rotating seat and is installed at a certain angle relative to the side of the road.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] like Figures 1-4 As shown, the first embodiment of this utility model provides a highway slope displacement monitoring and early warning device, comprising: Stress circuit breaker 1 is fixed on the slope surface of the slope to be monitored and is used for landslide displacement detection. The road closure execution mechanism 2 is set on the highway side at the toe of the slope to be monitored. The road closure execution mechanism 2 is connected to the stress circuit breaker mechanism 1 through the circuit breaker detection circuit 3. The road closure execution mechanism 1 is used to realize the functions of road closure and early warning.

[0020] The stress-breaking mechanism 1 includes a housing 101, with multiple wire openings evenly distributed circumferentially on the outer side of the housing 101. Each wire opening contains a stress-breaking PCB 102, and a pad island 103 is located in the middle of the stress-breaking PCB 102. The pad island 103 is bridged with each stress-breaking PCB 102 to enable electrical conduction within each wire opening. At least two of the wire openings contain copper wires 104 soldered to the pad island 103, and the copper wires 104 extend out of the housing and connect to the circuit breaking detection circuit 3. The copper wires 104 extending out of the wire openings can be flexibly arranged according to the monitoring area, such as extending from two vertically opposite wire openings in the housing or from two horizontally opposite wire openings in the housing, thus improving adaptability.

[0021] The casing 101 is a round or square box. The round or square box is made of ABS plastic.

[0022] At least four wire openings are provided. For a circular box, four wire openings are evenly distributed around the outer circumference of the box. For a square box, wire openings are provided on all four sides of the box. The stress-breaking PCB 102 is correspondingly installed in each wire opening, and each stress-breaking PCB 102 is connected to the pad island 103 bridge located in the middle, so that the internal electrical conduction of each wire opening is achieved.

[0023] Copper wire 104 is a 2.5 square millimeter single-core copper wire.

[0024] In the design of the stress-breaking PCB102, the stress level of the PCB bridge can be adjusted by changing the width and length of the bridge. In this embodiment, the bridge width of the stress-breaking PCB102 is designed to be 1.2-1.5mm, and the bridge length is designed to be 5-8mm, so that the stress value of the PCB bridge is adjusted to 20-25kg. That is, when a 2.5 square millimeter conductor is subjected to a 20kg outward horizontal pulling force, the pad island 103 will break four bridges under the external force, causing the 2.5 square millimeter conductor to lose its electrical connection with the other three openings.

[0025] The on-site arrangement of the stress-breaking mechanism 1 is as follows: multiple stress-breaking mechanisms 1 are connected in series, and the arrangement route of the multiple series-connected stress-breaking mechanisms 1 is perpendicular to the landslide direction. The multiple series-connected stress-breaking mechanisms 1 are laid in the landslide area, and the copper wires at the beginning and end of the multiple series-connected stress-breaking mechanisms 1 are connected to the circuit breaker detection circuit 3, while the middle section is fixed on the slope surface where there is no landslide. Under normal working conditions, the stress-breaking PCB 102 remains connected to the copper wire 104, and the circuit breaker detection circuit 3 is not energized; when the slope shifts, the stress-breaking PCB 104 is disconnected from the copper wire 104, energizing the circuit breaker detection circuit 3.

[0026] Specifically, multiple interconnected stress-breaking mechanisms 1 are electrically connected via their respective copper wires 104. These interconnected stress-breaking mechanisms 1 are positioned at potential sliding surfaces, with their ends connected to the circuit breaker detection circuit 3. The middle sections are fixed to the stable slopes on both sides of the potential sliding surface, forming a "Z"-shaped monitoring network. During deployment, the multiple interconnected stress-breaking mechanisms 1 are positioned at potential sliding surface locations, and each stress-breaking mechanism 1 is fixed by steel piles driven 30-35cm into the ground. Adjacent stress-breaking mechanisms 1 are repeatedly laid along the landslide body from top to bottom at intervals of 5-8m. The middle sections of the multiple interconnected stress-breaking mechanisms 1 are fixed to the stable slopes on both sides of the potential sliding surface by anchor bolts, forming a "Z"-shaped monitoring network.

[0027] A control box is installed on the roadside at the toe of the slope to be monitored, near the road closure actuator 2. The circuit breaker detection circuit 3 includes a normally closed relay and a power supply housed in the control box. One leg of the relay coil is connected to the positive terminal of the power supply, and the other leg is connected to the first end of the stress-breaking mechanism 1. The tail end of the stress-breaking mechanism 1 is connected to the negative terminal of the power supply. One end of the normally closed contact of the relay is connected to the positive terminal of the power supply, and the other end is connected to one end of the road closure actuator 2 and the other end is connected to the negative terminal of the power supply. Specifically, a 12V DC power supply is used in the control box, and the normally closed relay model is HH52P. When a landslide occurs, the circuit of the stress-breaking mechanism 1 is broken, the relay coil is de-energized, the normally closed contact returns to the closed state, thereby connecting the road closure actuator 2 to the power supply, realizing the circuit breaker detection and early warning triggering functions.

[0028] The road closure execution mechanism 2 includes a barrier gate, which adopts an existing ordinary gravity barrier gate arm. The ordinary gravity barrier gate arm includes a support frame 201 and a gate arm 202. The support frame 201 is set on the side of the highway. The lower end of the gate arm 202 is rotatably connected to the support frame 201 through a rotating seat 203, and is installed at a certain angle relative to the side of the highway. Preferably, the vertical angle between the gate arm 202 and the support frame 201 is 10-15 degrees. The tail of the gate arm 202 is connected to a release device through a steel wire 204. The unhooking device is an existing electric unhooking device. Specifically, the electric unhooking device includes a mounting box 205 fixed to the support frame 201 and located near the lower end of the gate arm 202. A mounting groove is provided on the side of the mounting box 205 near the gate arm 202, and a locking tongue 206 is movably connected within the mounting groove. An electromagnet is located inside the mounting box 205, opposite to the locking tongue 206. The electromagnet is connected to the circuit breaker detection circuit 3. A steel wire 204 is suspended on the locking tongue 206, with the end of the steel wire 204 away from the locking tongue 206 connected to the tail of the gate arm 202. Specifically, the unhooking device is a DC 12V electromagnetic unhooking device.

[0029] Under normal operating conditions, one end of the steel wire 204 is fixed to the tail of the gate arm 202, and the other end is connected to the locking tongue 206 of the unhooking device. The gate arm 202 is in the raised state, the unhooking device is not energized, and the gate arm 202 is bound by the steel wire 202 and cannot be lowered. The steel wire 202 is in a taut state. When the unhooking device is energized, the locking tongue 206 is retracted under the magnetic attraction of the electromagnet, which in turn causes the steel wire 204 connected to the gate arm 202 to be released from restraint. The gate arm 202 moves downward naturally under the action of gravity and completes its lowering within 5 seconds, finally blocking the road and achieving the purpose of road closure.

[0030] Alternatively, the road closure execution mechanism 2 includes a barrier gate, warning lights, and a buzzer. The tail of the barrier gate arm 202 is connected to a release device via a steel wire 204. The release device, warning lights, and buzzer are connected in parallel and are also connected to the circuit breaker detection circuit 3. Under normal operating conditions, the barrier gate arm 202 is in the raised state, the release device is not energized, and the arm 202 is bound by the steel wire 204 and cannot be lowered. When the release device is energized, the locking tongue 206 of the release device retracts, causing the steel wire 204 connecting the arm 202 to be released from its constraint. The arm 202 then moves downward naturally under the action of gravity, ultimately blocking the road and achieving the purpose of road closure. At the same time, the warning lights begin to flash and the buzzer sounds a warning sound to remind passing vehicles that passage is prohibited.

[0031] The working principle and process of this device: (1) On-site setup: In the landslide risk area of ​​the highway slope, multiple stress circuit breaking mechanisms 1 are connected in series and laid vertically along the landslide direction. Multiple interconnected stress circuit breaking mechanisms 1 are placed at the potential sliding surface. Each stress circuit breaking mechanism 1 is fixed by driving steel piles into the ground 30cm deep. Adjacent stress circuit breaking mechanisms 1 are laid repeatedly along the landslide body from top to bottom at 5-meter intervals. The copper wires at the beginning and end of multiple interconnected stress circuit breaking mechanisms 1 are connected to the circuit breaking detection circuit 3. The middle section is fixed on the stable slope on both sides of the potential sliding surface to form a “Z”-shaped monitoring network for real-time monitoring of the slope. (2) When a landslide occurs on the highway slope, the landslide body will slide down and drive the stress circuit breaker 1 to slide down synchronously. Since the middle of the line of the stress circuit breaker 1 is fixed on the slope surface that will not slide down, it will not slide down with the landslide surface. When the tensile force on any stress circuit breaker 1 reaches the limit value of 20kg, the four bridges of its internal stress circuit breaker PCB will be destroyed, and the copper wire will be disconnected from the electrical connection with other openings, resulting in the circuit of the stress circuit breaker 1 being broken. After the circuit detection circuit 3 detects the circuit being broken, the normally closed contact of the relay closes, and the gate release device, warning light, and buzzer are energized. The release device releases the steel wire 204, and the gate arm 202 falls down to block the road under the action of gravity. At the same time, the warning light flashes and the buzzer sounds, realizing timely early warning and road closure in the early stage of landslide.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
