[0026] Example

[0027] Please refer to Figures 1-4 This embodiment provides a tunnel inspection platform, including multiple inspection mechanisms installed in the tunnel. The multiple inspection mechanisms are electrically connected. Each inspection mechanism includes a housing 1, a control module 2, and a detection element for obtaining the concentration of pollutants in the tunnel. The detection element and the control module 2 are both disposed in the housing 1 and are electrically connected. An air inlet is provided on the housing 1, and the input end of the detection element is aligned with the air inlet. The control module 2 is connected to the control element of the fan in the tunnel by wired and / or wireless means.

[0028] In this embodiment, the aforementioned detection mechanism monitors the concentration of harmful gases in the tunnel in real time through built-in sensors. It can not only collect harmful gas concentration data, but also perform preliminary analysis and processing on this data, which facilitates risk management of the tunnel.

[0029] Specifically, the aforementioned housing 1 is used to install and protect the control module 2 and the detection element, preventing them from being exposed inside the tunnel. The aforementioned air inlet allows air to enter the tunnel. The detection element analyzes the composition of the gas entering the housing 1, and then the control element drives the fan to operate, effectively reducing the concentration of harmful gases inside the tunnel and improving tunnel safety. It should be noted that the detection mechanism monitors the concentration of harmful gases inside the tunnel in real time using built-in sensors and feeds the data back to the control module 2 in real time. Based on the harmful gas concentration data provided by the detection mechanism, the control module 2 can intelligently control the operation of the fan inside the tunnel. When the concentration of harmful gases exceeds a preset safety threshold, the control module 2 can automatically start or adjust the fan's operating mode to accelerate the discharge of harmful gases and the introduction of fresh air.

[0030] It should be noted that the control module 2 mentioned above is connected to the control element of the ventilation fan in the tunnel via wired and / or wireless means. Different communication connection methods are selected according to specific usage requirements, so that the control module can obtain the concentration data of harmful gases and directly control the operation of the ventilation fan in the tunnel.

[0031] Please refer to Figures 1-4In some embodiments of this example, the above-mentioned detection mechanism is provided with an installation component, which includes a base 4 and a limiting platform 5. The base 4 is used to connect with the tunnel, and the limiting platform 5 is disposed on the housing 1. The limiting platform 5 has a receiving groove 6, and the base 4 can extend into the receiving groove 6.

[0032] In this embodiment, the aforementioned installation assembly is used to fix the detection mechanism to the top of the tunnel. By installing multiple detection mechanisms in parallel, gas concentration data at different locations within the tunnel can be obtained, facilitating adjustments to the operation of the fan based on the data and improving the safety of tunnel use. Specifically, the aforementioned base 4 is used to connect to the inner wall of the tunnel. By fixing the base 4 to the inner wall of the tunnel, and then fixing the limiting platform 5 to the base 4, the entire detection mechanism can be easily disassembled and installed.

[0033] Please refer to Figure 1 and Figure 4 In some embodiments of this example, a baffle 7 is provided at one end of any side of the base 4, and the limiting platform 5 can abut against the baffle 7. A locking plate 8 is provided at the end of the limiting platform 5 away from the baffle 7, and the baffle 7 and the locking plate 8 are connected by bolts 9.

[0034] In this embodiment, the baffle 7 is used to limit the positioning platform 5. The positioning platform 5 is pushed into the receiving groove 6 by hand. When the positioning platform 5 abuts against the baffle 7, it indicates that the base 4 has completely entered the receiving groove 6. Finally, the locking plate 8 and the baffle 7 are fixed by bolts 9, thereby realizing the fixation of the entire detection mechanism.

[0035] Please refer to Figure 3 In some embodiments of this example, the detection element includes an electrochemical sensor 3, which is connected to the control module 2.

[0036] In this embodiment, the electrochemical sensor 3 operates by reacting with the analyte and generating an electrical signal proportional to the concentration of the analyte. This electrical signal can be current, voltage, or resistance, etc. When the analyte reacts with the sensitive electrode within the sensor, an electrochemical reaction occurs, leading to a change in the electrical signal. By measuring these changes in electrical signals, quantitative or qualitative analysis of the analyte can be achieved. The electrochemical sensor 3 can effectively acquire data on harmful gases within the tunnel, facilitating data-driven adjustment of the ventilation fan's operation, improving the intelligence of the ventilation fan's operation within the tunnel, and promoting energy conservation and environmental protection.

[0037] Please refer to Figure 3 In some embodiments of this example, a guide fan 10 is provided at the air inlet.

[0038] In this embodiment, the aforementioned airflow guide fan 10 is used to rapidly draw gas from outside the housing 1 into the housing 1. The airflow guide fan 10 generates airflow, accelerating the entry of harmful gases from the tunnel into the housing 1, thereby improving gas collection efficiency. By accelerating gas flow, harmful gases can come into contact with the sensors inside the housing 1 more quickly, thus improving detection sensitivity and ensuring that harmful gases can be detected promptly and accurately. In addition, the use of the airflow guide fan 10 can shorten detection time, enabling the tunnel detection platform to acquire harmful gas information more quickly, providing timely data support for tunnel safety management.

[0039] Please refer to Figure 2 and Figure 4 In some embodiments of this example, the air inlet is covered with a filter screen plate 11, a cleaning brush 12 is provided on the filter screen plate 11, and a drive component 13 for driving the cleaning brush 12 to swing is provided inside the housing 1. The drive component 13 is connected to the control module 2.

[0040] In this embodiment, the filter screen 11 is used to block large particles such as dust and suspended matter from entering the detection platform, protecting the internal sensors from contamination and damage. As a barrier, the filter screen 11 reduces the corrosive effects of the harsh tunnel environment on the internal equipment of the detection platform, extending its service life. The cleaning brush 12 automatically oscillates during filter screen 11 operation, brushing away dust, particles, and other impurities adhering to its surface, keeping the filter screen 11 clean and unobstructed. Through continuous cleaning, the cleaning brush 12 effectively prevents clogging of the filter screen 11 due to impurity accumulation, ensuring the detection platform can continuously and efficiently acquire harmful gases from the tunnel.

[0041] Please refer to Figure 3 In some embodiments of this example, a warning light 14 is provided on the housing 1, and the warning light 14 is connected to the control module 2.

[0042] In this embodiment, when the concentration of harmful gases in the tunnel exceeds a preset safety threshold, the warning light 14 will immediately illuminate, providing a clear visual alarm to the operators. The immediate alarm function of the warning light 14 can quickly attract the attention of the operators, enabling them to take immediate action, such as activating the ventilation system or evacuating personnel, thereby effectively shortening the emergency response time.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
