[0043] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, without paying creative labor, other drawings obtained based on these drawings still belong to the scope of the present invention.

[0044] Figure 1 A schematic structural diagram of an embodiment of a cable trench fire monitoring and processing system provided by the present invention;

[0045] Figure 2 A schematic diagram of the main process of an embodiment of a cable trench fire monitoring and processing method provided by the present invention. DETAILED DESCRIPTION

[0046] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] like Figure 1 FIG. 1 is a schematic diagram of a structure of an embodiment of a cable trench fire monitoring and processing system provided by the present invention; in this embodiment, the cable trench fire monitoring and processing system at least includes:

[0048] Fire extinguishing balls 1 are arranged at intervals in the cable trench and are used to trigger self-explosion and spray dry powder fire extinguishing agent when a fire is sensed;

[0049] In a specific example, the shell of the fire extinguishing ball 1 is a segmented plastic splicing structure, the interior is a foam sealing layer filled with dry powder fire extinguishing agent, and a fuse is provided in the fire extinguishing ball 1. When a fire is sensed, the fuse is triggered to cause the fire extinguishing ball 1 to heat up, expand and explode, and spray dry powder fire extinguishing agent;

[0050] The shell material of the fire extinguishing ball 1 has waterproof and flood-resistant properties, reaching IP68 level. Specifically, the fire extinguishing ball 1 adopts an integrated design, with high product integration, overall IP68 waterproof and flood-resistant, long product life and not affected by the external environment;

[0051] In the embodiment of the present invention, when a fire is sensed, the internal fuse is triggered and ignited, and the temperature in the fire extinguishing ball 1 rises and expands, breaking through the foam shell and exploding to extinguish the fire. At the same time, the explosion generates a shock wave, pushing away the air near the fire source, and at the same time spraying dry powder fire extinguishing agent to cover the fire source to complete the fire extinguishing and buzzing alarm. The outer shell is a segmented plastic splicing structure, and the interior is a foam sealing structure filled with dry powder fire extinguishing agent. After the explosion, the outer shell explodes in sections, and no plastic debris is formed.

[0052] In one example, the fire extinguishing ball 1 may have the following specifications:

[0053] Weight: 1KG

[0054] Product specifications: 85mm*231mm

[0055] Fire extinguishing agent: dry powder (non-toxic)

[0056] Fire extinguishing area: 4-6m 2

[0057] Response time: ≤3s

[0058] Validity period: 5 years (no maintenance required)

[0059] Alarm loudness: 120db

[0060] Ambient temperature: -10℃~85℃.

[0061] The sensing module 2 is integrated in or near the fire extinguishing ball system and is used to monitor the environmental parameters, gas concentration and fire situation in the cable trench in real time, send out an alarm signal according to the preset alarm threshold, and trigger the lead in the fire extinguishing ball system after sensing the occurrence of a fire;

[0062] In a specific example, the environmental parameters and gas concentrations monitored in real time by the sensing sensor module 2 include but are not limited to ambient temperature, humidity, methane concentration, hydrogen sulfide concentration, and oxygen concentration, wherein the preset alarm threshold can be set and adjusted according to site requirements; specifically, the sensing sensor module 2 may include a gas quantity monitoring sensor, an environmental quantity monitoring sensor, etc.;

[0063] The sensing module 2 also includes a sensor with a flood monitoring function, which is used to detect flooding in the cable trench;

[0064] The sensing module can trigger an alarm when any of the following conditions is detected:

[0065] The ambient temperature exceeds 60°C;

[0066] Humidity exceeds 99.9%;

[0067] Methane content exceeds 3% VOL;

[0068] Hydrogen sulfide content exceeds 20ppm;

[0069] The oxygen level is less than 18%.

[0070] Specifically, the sensing module 2 has fire monitoring + overflow monitoring + environmental quantity + real-time monitoring of various gas quantities and data over-limit alarm, and the alarm threshold can be set according to site requirements. Under normal circumstances, if the ambient temperature in the cable trench exceeds 60°C and the humidity exceeds 99.9%, an alarm condition is constituted; when the amount of various gases exceeds the safety requirement value, an alarm condition is constituted. For example, methane gas is a flammable and explosive gas. When the methane content in the air is greater than 3% VOL, an alarm is issued because it will harm the cable trench; hydrogen sulfide is a toxic and harmful gas. When the content in the cable trench is greater than 20ppm, it will affect the personal safety of the operation and maintenance personnel when they enter the trench for construction; oxygen is a lower limit alarm. When the oxygen content in the trench is lower than 18%, it will endanger personal safety.

[0071] The communication module 3 is connected to the sensing module and is used to wirelessly transmit the monitoring data and alarm signals to the remote system platform or mobile phone APP 4. When the sensing module 2 detects abnormal gas or fire, other relevant information such as whether the internal environment of the cable trench is normal is pushed to the system platform for data operation and maintenance statistics and data application through the communication module 3, and is pushed to the mobile phones of relevant personnel in real time, which greatly reduces the workload of the operation and maintenance personnel, improves the operation and maintenance efficiency, and improves the operation quality of the cable trench.

[0072] In a specific example, the communication module 3 uses an LTE communication management platform to collect and manage data, and provide data support for subsequent services and customers, such as gas monitoring data analysis. LTE communication technology uses the base station of the mobile operator, so the communication distance is up to tens of kilometers.

[0073] More specifically, the system of the present invention further comprises:

[0074] The system platform or mobile phone APP4 is used to receive, process, and display monitoring data and alarm signals, and provide data recording, analysis, and alarm functions. Specifically, the mobile phone APP and the IoT operation and maintenance platform, as system application components, can record, analyze, display, and alarm data. Through real-time monitoring of the on-site use environment and real-time supervision of the cable operation status, advanced applications can be realized, with cable trench fire warning, alarm, and fire extinguishing functions.

[0075] In some examples, the system of the present invention further comprises:

[0076] Buzzer: When the fire extinguishing ball 1 is triggered, the buzzer starts at the same time, emitting an alarm sound of at least 120dB.

[0077] It is understood that the implementation of the present invention has the following advantages:

[0078] Integrated design: The present invention improves the response speed and processing efficiency to cable trench fires by integrating monitoring, early warning and fire extinguishing functions into one system.

[0081] Strong environmental adaptability: The fire extinguishing ball shell has IP68 waterproof and anti-flooding performance, suitable for various harsh environments.

[0082] High safety: The dry powder fire extinguishing agent filled inside the fire extinguishing ball is non-toxic, reducing the harm to the environment and personnel.

[0083] Easy maintenance: The fire extinguishing ball is effective for at least 5 years and requires no maintenance, which reduces long-term operating costs.

[0084] Remote monitoring and alarm: Through the communication module and system platform, remote monitoring and alarm can be realized, which improves the operation and maintenance efficiency.

[0085] Data recording and analysis: The system platform can record and analyze monitoring data, provide long-term monitoring and trend prediction, and help prevent fires.

[0086] User-friendly interface: The mobile app and IoT operation and maintenance platform provide a user interface for operation and maintenance personnel to set alarm thresholds and view historical data.

[0087] Long-term stability: The system is designed with long-term stable operation in mind, including regular inspection and maintenance of modules.
