Description

Technical Field

[0001] The utility model relates to the technical field of early warning systems, and more specifically to an early warning system for sudden accidents on highway bridges. Background Art

[0002] At present, highway bridges are unable to provide early warning when they are hit by sudden accidents, such as bridge pier collisions, sudden collapse of some bridge spans, or when they encounter natural disasters such as mountain torrents, mudslides, collapses, and landslides that cause damage to highway bridges and affect driving safety. They are unable to provide early warning to passing pedestrians and vehicles, resulting in huge losses of life and property. Utility Model Content

[0003] The purpose of the present invention is to provide a highway bridge accident early warning system in order to solve the above technical problems.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A highway bridge accident early warning system includes a controller, an early warning broadcaster and a data acquisition system, wherein the early warning broadcaster and the data acquisition system are both electrically connected to the controller;

[0006] The data acquisition system consists of a vibration sensor, a gyroscope sensor, an inclination sensor and an infrared radiation sensor. Each bridge pier is equipped with one of the vibration sensors.

[0007] The early warning system also includes fixed brackets, one for each guardrail on either side of the bridge, and symmetrically arranged. These brackets are used to mount gyroscope sensors, tilt sensors, and infrared sensors. The vibration sensors installed on the bridge piers are gyroscope sensors.

[0008] The fixing bracket includes a connecting rod, a mounting plate is provided at the bottom of the connecting rod, and the infrared radiation sensor is installed on the mounting plate; an outer splint is provided at the top of the connecting rod, the outer splint is provided on the outside of the guardrail, and the inner splint is provided on the inside of the guardrail, and the four corners of the outer splint and the inner splint are connected and fixed by screws and nuts;

[0009] The inner plate is provided with a mounting groove on one side away from the outer plate, and mounting steps are provided around the mounting groove. A cover plate is provided on the mounting step, and the cover plate is screwed to the mounting step.

[0010] The gyroscope sensor and inclinometer are fixed to the bottom of the mounting slot. It's important to note that the mounting brackets on both sides are symmetrically arranged, so they can be considered paired and evenly spaced. The infrared sensor includes an infrared transmitter and an infrared receiver. Within a pair of mounting brackets, the mounting plate in one bracket is used to mount the infrared transmitter, while the mounting plate in the other bracket is used to mount the infrared receiver.

[0011] The mounting step is provided with an annular sealing strip with a T-shaped cross section, the bottom of which is embedded in the mounting step. Dust and rain are common on bridges, and these can easily enter the mounting grooves and damage the gyroscope and inclination sensors. The annular sealing strip prevents dust and rain from entering, providing protection. The T-shaped cross section of the annular sealing strip improves sealing performance.

[0012] The gyro sensor and tilt sensor are covered with a silicone protective layer bonded to the bottom of the mounting slot. This layer provides secondary protection for the gyro sensor and tilt sensor, ensuring continued waterproof and dustproof protection even if the annular sealing strip is damaged, extending their service life.

[0013] The side wall of the inner clamping plate is provided with a wire groove which is communicated with the mounting groove and is used for passing electric wires.

[0014] The screw rod is provided around the outer splint, and through holes are provided around the inner splint. The screw rod and the outer splint are integrally formed, and the screw rod passes through the guardrail and the through holes in sequence and is connected with the nut.

[0015] The connecting rod, the mounting plate and the outer clamping plate are integrally formed or fixed by welding.

[0016] The outer and inner plates are both provided with a rubber friction layer on the side where they are close to each other, and a plurality of evenly arranged convex strips are provided on the rubber friction layer. The rubber friction layer can fill the gap between the outer and inner plates and the guardrail, thereby increasing friction and improving stability.

[0017] The early warning broadcaster is a high-gain penetrating broadcaster. The high-gain penetrating broadcaster is installed at both ends of the bridge to warn passing vehicles and personnel.

[0018] Vibration sensors, gyroscope sensors, tilt sensors and infrared sensors are used to collect real-time road condition data and transmit the data to the controller, which transmits the data to the monitoring center;

[0019] Vibration sensors are installed on bridge piers to detect abnormal vibrations, such as those caused by ship collisions, car collisions, or natural disasters. Once the threshold is exceeded, high-gain penetrating broadcasts are used to notify passing vehicles and pedestrians of the abnormal bridge ahead and transmit the abnormal data to the monitoring center.

[0020] By installing gyroscope sensors and tilt sensors on the guardrails, when an emergency occurs on the bridge, such as a car hitting the guardrail, or a ship or car collision or natural disaster causes the guardrail to vibrate or tilt abnormally, once the set threshold is exceeded, high-gain penetrating broadcast will be used to notify passing vehicles and pedestrians of the abnormal event ahead of the bridge, and the abnormal data will be transmitted to the monitoring center at the same time.

[0021] By installing infrared counter-radiation sensors on the outside of the guardrail, when an emergency occurs on the bridge, such as a ship collision, a car collision, or a natural disaster, which causes the beams and slabs to fall or collapse, resulting in the interruption of the infrared signal received by the infrared counter-radiation sensor receiving end, high-gain penetrating broadcast will be used to inform passing vehicles and pedestrians of the abnormal event on the bridge ahead in advance, and at the same time transmit the abnormal data to the monitoring center.

[0022] The beneficial effects of the utility model are as follows:

[0023] By setting up vibration sensors, gyroscope sensors, tilt sensors and infrared radiation sensors, all-round data collection is carried out on the bridge, which improves the comprehensiveness of early warning, timely reminds passing vehicles, and improves the driving safety of the bridge; the design of annular sealing strips can prevent dust or rainwater from entering, playing a protective role. The cross-section of the annular sealing strip is a T-shaped structure, which improves the sealing performance; by setting up a rubber friction layer, the gap between the outer and inner plywood and the guardrail can be filled, thereby increasing friction and improving stability.
