Description

Technical Field

[0001] The utility model relates to the technical field of collapse alarm, in particular to a collapse alarm device. Background Art

[0002] Human development is inseparable from roads, railways, river embankments, etc. Sometimes, under the influence of natural or human forces, the collapse of rock and soil will inevitably occur. This phenomenon cannot be predicted in advance. When it occurs, it will cause property losses such as buildings and vehicles, and even endanger personal safety. Sometimes it is not possible to let people around know in time after it happens. For example, when the road surface or embankment collapses at night, pedestrians and vehicles cannot detect the danger in time in the dark or at a high speed, which will cause irreparable losses. Utility Model Content

[0003] The utility model aims to provide a collapse alarm device which can monitor the collapse of road surface and give an alarm when collapse occurs.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A collapse alarm device comprises a two-core optical cable, wherein two ends of one optical cable are respectively connected to an optical fiber transmitter and an optical fiber receiver, the optical fiber receiver is connected to a main controller, and the main controller is connected to a plurality of alarm lights and an alarm.

[0006] Another optical cable is connected to an optical fiber breakpoint tester, and the optical fiber breakpoint tester is connected to the main controller.

[0007] The two-core optical cables are pre-buried under the roadbed.

[0008] The warning lights are arranged along the road.

[0009] The alarm is an audible and visual alarm.

[0010] The main controller and the alarm are arranged in the duty room.

[0011] The alarm light is powered by UPS, wind-solar hybrid power generation or photovoltaic panel power generation.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model pre-buries the optical cable in the roadbed. When the road collapses or breaks, the optical fiber receiver cannot receive the signal, thereby triggering the alarm mechanism. The alarm lights arranged along the road can prompt passers-by or high-speed vehicles, and the alarm can also be used to prompt the on-duty personnel. In this way, the problem of road collapse can be solved efficiently and timely, ensuring that people, vehicles and property are not subject to greater losses, and the safety of roads or embankments can be guaranteed around the clock.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 As shown, a technical solution provided by the utility model:

[0018] A collapse alarm device comprises a two-core optical cable 2, wherein two ends of one optical cable are respectively connected to an optical fiber transmitter and an optical fiber receiver, the optical fiber receiver is connected to a main controller, and the main controller is connected to a plurality of alarm lights 3 and an alarm.

[0019] Another optical cable is connected to an optical fiber breakpoint tester, and the optical fiber breakpoint tester is connected to the main controller.

[0020] The two-core optical cable is pre-buried under the roadbed 1 of the road. When used in the river bank, it is pre-buried under the bank and buried with backfill material.

[0021] As shown in the figure, the warning lights 3 are set every 50 meters or 100 meters along the road, and are set on one side or both sides of the road. The warning lights can be LED dot matrix lights, which can be controlled by the main controller to display different warnings, and can be flashing style prompts or no-passing style prompts. The warning lights are powered by UPS, wind-solar hybrid power generation, or photovoltaic panel power generation, and are powered independently, and will not be affected by ground collapse or fracture.

[0022] The alarm is an audible and visual alarm that can broadcast a prompt of road collapse and simultaneously indicate the distance to the collapsed area.

[0023] The main controller and the alarm are arranged in the duty room.

[0024] Assume that a unit manages a 100-kilometer road section and lays a 100-kilometer two-core optical cable 2 in the middle of the lane and pre-buries it under the roadbed 1.

[0025] At the beginning of the road, one of the optical fibers is installed with a fiber breakpoint tester with an accuracy of meter level, the other optical fiber is installed with a fiber optic receiver, and the end is installed with a fiber optic transmitter.

[0026] When there is a collapse 4 or a break on the road, the two-core optical cable 2 is disconnected, and the optical fiber breakpoint tester detects the breakpoint distance and sends it to the main controller. At the same time, the optical fiber receiver sends a signal to the main controller because it cannot receive the signal. The main controller sends two signals, one of which is provided to the alarm, which sends an audible and visual alarm, broadcasts the prompt of road collapse, and prompts the distance of the collapse, reminding the on-duty personnel to deal with it in time, and the other is provided to the alarm light 3, which emits a red light or displays a sign prohibiting passage, reminding the driver or pedestrian to slow down and stop, and stop moving forward. The staff can report the precise location provided by the optical fiber breakpoint tester, go to deal with it quickly, and wait for the road management to complete the processing before passing.

[0027] The optical cable will break if its tensile strength exceeds one centimeter. Therefore, as long as the road surface breaks and causes the optical cable to break or twist too much, it will trigger the alarm and warning light. This plays an important role in road surface fracture detection and can ensure the safety of passers-by and vehicles to the greatest extent.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
