Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to an underground space information monitoring system based on disaster analysis. Background Art

[0002] During underground construction, such as mining, tunneling, and subway construction, the relatively enclosed underground space and poor air circulation can easily lead to the accumulation of harmful gases such as methane and carbon dioxide. This can also cause temperature anomalies, fire hazards, oxygen level fluctuations, unstable temperature and humidity, rising water levels, and increased vibration. Monitoring equipment has become an indispensable tool for ensuring underground construction safety.

[0003] At present, during underground construction, mining may release flammable gases such as methane. Tunnel excavation or subway construction may also leak flammable gases when encountering oil and gas strata. These gases are easy to accumulate in closed underground spaces and may cause fires when encountering sparks from construction equipment, electrical short circuits and arcs. The high temperature generated by the fire will melt the casing, lines and internal components of the monitoring equipment, causing it to stop working. It may also burn the power supply cable or cause a short circuit in the line, resulting in a power outage in the monitoring equipment. Once the power is cut off, the monitoring equipment stops working, making it impossible for ground rescue personnel to obtain real-time information from the underground, which hinders the rescue operation. Therefore, this application provides an underground space information monitoring system based on disaster analysis to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an underground space information monitoring system based on disaster analysis to solve the problem that the existing monitoring equipment is prone to cable damage, power supply line short circuit, etc. when a disaster occurs, thereby causing power outages in the monitoring equipment.

[0008] The buffer assembly includes: a base, which is arranged on the bottom plate, and the camera is slidably arranged with the base; and a plurality of connecting members, one end of which is arranged in the base and the other end is connected to the camera.

[0009] It also includes: a slide rod, which is arranged in the base; two sliders, which are arranged on the slide rod and are symmetrically arranged; and a connecting rod, one end of which is movably arranged on the slider and the other end is connected to the camera.

[0010] It also includes: a tension spring, which is arranged between the two sliders and is used to provide a restoring elastic force for the two sliders.

[0011] The camera includes: a monitoring sensing module, including a temperature sensor, a fire detector, a toxic and harmful gas sensor, an oxygen monitor, a temperature and humidity sensor, a water level sensor and a vibration sensor, which are used for real-time monitoring of the underground space.

DETAILED DESCRIPTION

[0029] The following describes in detail the underground space information monitoring system based on disaster analysis provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are optimal and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0030] like Figure 1 - Figure 6 As shown, an embodiment of the present invention provides an underground space information monitoring system based on disaster analysis, including: a base plate 1; a buffer component 2, arranged on the base plate 1; a camera 4, arranged on the buffer component 2, and a backup power supply is provided in the camera 4; a first protective shell 5, arranged on the base plate 1, and the first protective shell 5 is semicircular; a second protective shell 3, slidably arranged in the first protective shell 5, and is semicircular; a protection mechanism 6, arranged on the base plate 1, for driving the second protective shell 3 to rotate.

[0031] By providing the second protective shell 3 and the first protective shell 5, the camera 4 can be fully wrapped and protected to prevent objects from directly hitting the camera 4, avoiding the camera 4 from having its outer shell broken or its internal components damaged. At the same time, the second protective shell 3 and the first protective shell 5 can have the advantages of high strength and high toughness, high temperature resistance and corrosion resistance.

[0032] The protective mechanism 6 includes a slide 61 disposed on the base plate 1; a rotary mechanism 62 slidably disposed within the slide 61 for movement along the slide 61; and one end of the second protective shell 3 connected to the rotary mechanism 62. The rotary mechanism 62, upon receiving a start signal, moves along the slide 61, providing a power source for the movement of the second protective shell 3, allowing the two semicircular protective shells to quickly transition from an initially open state to a closed state.

[0033] The buffer assembly 2 includes a base 21 mounted on the base plate 1, with the camera 4 slidingly mounted thereon; and a plurality of connectors 22, one end of which is disposed within the base 21 and the other end of which is connected to the camera 4. The connectors 22 include a telescopic rod with a stop plate mounted thereon, and a spring body connected at one end to the stop plate and at the other end to the inner cavity of the base 21. When the camera 4 slides along the base 21, the telescopic rod contracts, compressing the spring body and providing elastic force for the subsequent reset of the camera 4.

[0034] It also includes: a slide bar 24 arranged in the base 21; two sliders 23 arranged on the slide bar 24 and symmetrically arranged; a connecting rod 25, one end of which is movably arranged on the slider 23 and the other end is connected to the camera 4.

[0035] The system also includes a tension spring 26 disposed between the two sliders 23 to provide a restoring force for the two sliders 23. The sliders 23 are pushed by the connecting rod 25 to move, thereby squeezing the tension spring 26. The elastic deformation of the tension spring 26 and the reciprocating motion of the slider 23 on the slide rod 24 gradually dissipate vibration energy, ensuring that the camera 4 remains relatively stable in complex vibration environments. This allows the monitoring sensor module 41 to continuously and accurately acquire environmental information about the underground space, preventing issues such as image blur and data acquisition errors caused by vibration interference.

[0036] The camera 4 includes: a monitoring sensing module 41, including a temperature sensor, a fire detector, a toxic and harmful gas sensor, an oxygen monitor, a temperature and humidity sensor, a water level sensor and a vibration sensor, which is used for real-time monitoring of the underground space.

[0037] By setting up a monitoring sensing module 41, including a monitor and a sensor, the monitor monitors the underground space, and the sensor monitors the underground space; for example, the temperature sensor monitors the temperature in the underground space, and once the temperature rises abnormally, a light flashing alarm will be issued to remind personnel; the fire monitor includes a smoke sensor and a flame sensor. When there is smoke in the underground space, the light emitted by the light source is scattered or absorbed by the smoke particles, causing the light signal received by the receiver to change, and then a sound alarm is issued; or when the ultraviolet light emitted by the flame is detected, an electrical signal output will be generated, which can quickly respond to the generation of flames, thereby issuing a sound alarm; the toxic and harmful gas sensor includes monitoring of carbon monoxide, hydrogen sulfide and volatile organic compounds, and once detected, an sound and light alarm will be triggered; the oxygen monitor can accurately measure the oxygen content in the underground space, and once Once the oxygen content in the underground space is lower than the set safety lower limit, a low oxygen alarm is triggered; the temperature and humidity sensor uses the characteristic that the capacitance of the humidity-sensitive capacitor changes with the humidity, and combines it with temperature sensitive elements to measure temperature and humidity. It can provide temperature and humidity data in real time. Once the humidity is detected to be higher than the set upper limit, a continuous beeping sound or an intermittent sharp sound alarm is triggered; the water level sensor can emit ultrasonic pulses and then receive the echo reflected from the water surface. The water level height is calculated based on the ultrasonic round-trip time. Once the monitored water level changes, a voice alarm is triggered; the vibration sensor uses the piezoelectric effect of piezoelectric materials. When the sensor is subjected to vibration acceleration, the piezoelectric material will generate an electric charge. The size of the charge is proportional to the acceleration, which can accurately measure the vibration conditions of the underground space. Once detected, a voice, light and sound alarm will be triggered.

[0038] The system also includes an emergency protection module 43, electrically connected to the monitoring and sensing module 41, for activating the protection mechanism 6 upon detecting an abnormality. By providing the emergency protection module 43, the system receives real-time environmental information from the monitoring and sensing module 41. When the monitoring and sensing module 41 detects an abnormality in the underground space environment, the emergency protection module 43 quickly identifies these abnormal signals and, based on the abnormality, activates protective measures to protect the camera 4.

[0039] The system also includes a restart module 42, electrically connected to the emergency protection module 43, for automatically restarting the monitoring equipment when the environment returns to normal. By providing restart module 42, when the emergency protection module 43 determines that the underground space environment has returned to normal, the restart module 42 receives a corresponding signal, thereby automatically switching the monitoring system from a protection state to a normal operating state. The backup power supply provides power to the camera 4, providing rescue personnel with continuous underground space information, helping them to adjust rescue strategies according to the latest situation and ensure the continuity and scientific nature of rescue operations.

[0040] The radius of the first protective shell 5 and the radius of the second protective shell 3 are both larger than the radius of the buffer assembly 2. This ensures that the buffer assembly 2 can be completely accommodated in the protective space formed by the two protective shells. The camera 4 is arranged on the buffer assembly 2, so it is indirectly more fully protected.

[0041] The maximum diameter of the second protective shell 3 matches the inner diameter of the first protective shell 5. This ensures that when the protection mechanism 6 drives the second protective shell 3 to rotate and close, the two protective shells can fit tightly together, effectively preventing foreign matter such as dirt and gravel from entering the protective shells and avoiding damage to the camera 4 and the buffer assembly 2.

[0042] The technical solution provided by the present invention is that when the monitoring sensing module 41 detects an abnormal situation in the underground space environment, the emergency protection module 43 immediately starts the protection mechanism 6 after receiving the abnormal signal, and the rotating machine 62 moves along the slide 61, so that the second protective shell 3 moves synchronously until it gradually closes with the first protective shell 5 to form a relatively closed protection space, thereby protecting the camera 4 and disconnecting the camera 4 from the external power supply. At the same time, if an external force impacts the camera 4, the camera 4 slides along the base 21 and pushes the slider 23 to move through the connecting rod 25 to absorb and disperse its impact force; when a disaster occurs, the rotating machine 62 moves, driving the second protective shell 3 to move synchronously, so that the second protective shell 3 is reset, the camera 4 is exposed, and the camera 4 is restarted to work normally through the backup power supply.

[0043] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
