Description

Technical Field

[0001] This invention relates to the field of railway disaster alarm devices, and in particular to a railway guardrail monitoring and alarm device and method. Background Technology

[0002] Landslides, mudslides, and other geological hazards along railway lines pose a significant threat to train operations. Therefore, their investigation, prediction, protection, and monitoring are crucial for the safe operation of railway transportation. By employing retaining walls, anchor bolts, steel mesh, drainage systems, and lattice structures in areas prone to landslides, mudslides, and rockfalls, protective measures have played a significant role in preventing geological disasters. However, protective measures alone are far from sufficient to ensure safe railway operation; therefore, various types of railway disaster prevention and safety monitoring systems are used along railway lines.

[0003] 1. A system for monitoring disasters such as wind, snow, and rain: The impact of natural disasters such as wind, snow, and rain on railway operations, especially in mountainous railway sections, varies depending on the specific terrain and railway protection measures. Therefore, monitoring of meteorological conditions such as wind, snow, and rain that reach disaster levels requires comprehensive processing of various data, including measured data, historical data, meteorological forecast data, and empirical data, to provide alarms and warnings.

[0004] 2. Slope Monitoring System: By continuously and in real-time monitoring slope surface displacement, soil internal displacement, rainfall, soil moisture content, water level changes, etc., the system can assess the overall stability before a disaster occurs and quickly issue early warning reports of disasters.

[0005] 3. Foreign Object Intrusion Detection System: This system uses technologies such as lasers and image analysis to detect foreign objects intruding into the railway.

[0006] Considering the cost and engineering difficulty, all of the above-mentioned monitoring systems are unlikely to achieve full-section monitoring along the railway line. Due to uncontrollable factors such as wind and snow, human activities, and earthquakes, it is inevitable that previously safe areas will become unsafe, which increases the difficulty of the layout and deployment of monitoring equipment. Therefore, even if disaster prevention monitoring equipment is installed along the high-speed railway line, traffic accidents caused by geological disasters still occur from time to time. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology, where even if disaster prevention and monitoring equipment is installed along high-speed railways, traffic accidents caused by geological disasters still occur from time to time. This invention provides a railway guardrail monitoring and alarm device and method.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0009] A railway guardrail monitoring and alarm device includes: multiple guardrail units, each guardrail unit including: two posts, a protective net and a base, the posts being disposed above the base, the protective net being fixedly connected to the two posts, the guardrail unit further including: several tilting circuit breakers and several circuit breaker detection lines, the circuit breaker detection lines being disposed between the two posts and fixedly installed on the two posts, and several tilting circuit breakers being connected in series on each circuit breaker detection line;

[0010] The guardrail monitoring and alarm device also includes a detection device, which is electrically connected to the circuit breaker detection line.

[0011] The above technical solution uses a detection line and a tilting circuit breaker connected in series to detect the status of the guardrail. When a geological disaster causes the detection line to break or the guardrail to tilt, the electrical connection of the line is broken, the handshake signal of the detection equipment is abnormal, and an alarm signal is issued. The principle is simple, the cost is low, and the installation is convenient. It provides a new monitoring method for geological disaster detection along the entire high-speed railway, preventing traffic accidents caused by geological disasters.

[0012] As a preferred embodiment of the present invention, the tilting circuit breaker includes a housing, a cable cage, and a falling object. The cable cage is disposed in the housing, and a first column extending into the cable cage is disposed in the housing. The first column supports the falling object. The cable cage includes a plurality of cables connected in series. The falling object can cut any one or more of the cables when it falls from the first column.

[0013] As a preferred embodiment of the present invention, the cable cage includes a cage wall, and the cage wall includes a plurality of cables arranged in a row, wherein the distance between adjacent cables is less than the diameter of the falling object.

[0014] As a preferred embodiment of the present invention, each of the guardrail units is equipped with at least two circuit breaker detection lines.

[0015] On the other hand, a railway guardrail monitoring and alarm method is disclosed, which uses any of the guardrail monitoring and alarm devices described above, including: the guardrail tilts, the falling object in the tilt circuit breaker causes the tilt circuit breaker to break the circuit, the detection device fails to handle the handshake, and an alarm signal is issued;

[0016] The detection line was broken, the detection device failed to handle the problem, and issued an alarm signal.

[0017] Using the above technical solution, when a geological disaster causes the detection line to break or the guardrail to tilt, the electrical connection of the line is broken, the handshake signal of the detection equipment is abnormal, and an alarm signal is issued. The principle is simple, the cost is low, and the installation is convenient.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: by connecting the detection line and the tilting circuit breaker in series, the status of the guardrail is detected. When the detection line breaks or the guardrail tilts due to geological disasters, the electrical connection of the line is broken, the handshake signal of the detection equipment is abnormal, and an alarm signal is issued. The principle is simple, the cost is low, and the installation is convenient. It provides a new monitoring method for geological disaster detection along the entire high-speed railway, and prevents traffic accidents caused by geological disasters. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0025] Example 1

[0026] A railway guardrail monitoring and alarm device, such as Figure 1 and 2 As shown, it includes: multiple guardrail units, each guardrail unit including: two posts 1, a protective net 2 and a base, the posts 1 being disposed above the base, the protective net 2 being fixedly connected to the two posts 1, the guardrail unit also including: several inclined circuit breaker devices 4 and several circuit breaker detection lines 3, the circuit breaker detection lines 4 being disposed between the two posts 1 and fixedly installed on the two posts 1, and several inclined circuit breaker devices being connected in series on each circuit breaker detection line 3;

[0027] The guardrail monitoring and alarm device also includes a detection device, which is electrically connected to the circuit breaker detection line 3.

[0028] Specifically, the tilting circuit breaker is a normally closed tilting circuit breaker that does not require a power supply. It is connected in series with the circuit breaker detection line 3 to form a fracture tilt detection system. Once the column 2 tilts, the circuit will be immediately broken, and subsequent straightening will not allow the circuit breaker detection line 3 to be connected. This prevents the tilting circuit breaker from being abnormally straightened due to the impact of mudslides after a collapse, thus preventing the system from missing the alarm.

[0029] Specifically, when the circuit breaker detection line 4 is intact and the column 2 is not tilted, the electrical connection of the circuit breaker detection line is intact, and the handshake signal of the detection equipment at both ends is normal. Once the circuit breaker detection line 4 is broken or the column 2 is tilted, the electrical connection of the line is broken, the handshake signal of the detection equipment at both ends is abnormal, and an alarm is triggered.

[0030] Each of the guardrail units is equipped with at least two of the circuit breaker detection lines.

[0031] The above technical solution uses a detection line and a tilting circuit breaker connected in series to detect the status of the guardrail. When a geological disaster causes the detection line to break or the guardrail to tilt, the electrical connection of the line is broken, the handshake signal of the detection equipment is abnormal, and an alarm signal is issued. The principle is simple, the cost is low, and the installation is convenient. It provides a new monitoring method for geological disaster detection along the entire high-speed railway, preventing traffic accidents caused by geological disasters.

[0032] Example 2

[0033] like Figure 3 As shown, the tilting circuit breaker includes a housing 5, a cable cage 6, and a falling object 7. The cable cage 6 is disposed inside the housing 5. A first column 8 extends into the cable cage 6 inside the housing 5. The first column 8 supports the falling object 7. The cable cage 6 includes several cables connected in series. The falling object 7 can cut any one or more of the cables when it falls from the first column 8.

[0034] Specifically, the inclined circuit breaker has a columnar structure, and the cable cage 6 is detachably connected to the box 5.

[0035] Specifically, the cable cage 6 is made of enameled copper wire with a diameter of 0.02mm and has a columnar structure.

[0036] Specifically, the cable cage 6 includes a cage wall, and the cage wall includes a plurality of cables arranged in a row, with the spacing between adjacent cables being smaller than the diameter of the falling object 7.

[0037] Specifically, the cable cage 6 has a through hole at the bottom, the box body 5 has a box bottom 9, the box bottom 9 has the column 4, and the first column 8 is adapted to the through hole.

[0038] Specifically, the housing 5 is equipped with a top limiting member 12 and a bottom limiting member 13. The top limiting member 12 is detachably connected to the cable cage 6, and the bottom limiting member 13 is detachably connected to the cable cage 6. The limiting members ensure a secure connection between the housing 5 and the cable cage 6 and provide support for the cable cage 6.

[0039] Specifically, the falling object 7 is a magnetized ball bearing. The magnetized ball bearing has micromagnetism, which causes the first column 8 to have a slight attraction force on the magnetized ball bearing, ensuring that the magnetized ball bearing will not fall out of the groove 10 under small-angle tilt and micro-vibration environment.

[0040] Specifically, the top of the first column 8 is provided with a groove 10, which is a V-shaped groove, and a ball bearing buffer pad is provided inside the groove 10, which plays a role in vibration resistance.

[0041] Specifically, such as Figure 4 As shown, the housing 5 is detachably connected to a locking pin 11, which penetrates the side wall of the housing 5 and extends into the cable cage 6 to restrain the falling object 7 within the column 4. The locking pin 11 prevents the cable cage 6 from breaking due to accidental tilting during transportation or other environmental conditions when the tilt circuit breaker is not in use.

[0042] The tilting circuit breaker does not rely on ball bearings for electrical connection; the ball bearings only participate in electrical circuit breaking. When in use, it must first be set vertically, and then the locking pin 11 is slowly removed. When the tilting circuit breaker tilts to a certain angle, the magnetized ball bearings in the groove 10 fall and strike the cable cage 6. When the tilt occurs slowly, the ball bearings strike the bottom of the cable cage 6 by gravity; when the tilt occurs rapidly, the ball bearings strike the wall of the cable cage 6. In either case, the cable cage 6 is damaged, forming an electrical circuit break; thus ensuring the reliability of railway disaster monitoring.

[0043] Example 3

[0044] A railway guardrail monitoring and alarm method, using the guardrail monitoring and alarm device described in Example 1, includes: the guardrail tilts, the falling object in the tilt circuit breaker causes the tilt circuit breaker to open, the detection device fails to handle the handshake, and an alarm signal is issued;

[0045] The detection line was broken, the detection device failed to handle the problem, and issued an alarm signal.

[0046] Using the above technical solution, when a geological disaster causes the detection line to break or the guardrail to tilt, the electrical connection of the line is broken, the handshake signal of the detection equipment is abnormal, and an alarm signal is issued. The principle is simple, the cost is low, and the installation is convenient.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
