[0049] Please see Figures 1 to 5 This embodiment provides a patrol vehicle for detecting harmful gas leaks, including: a chassis, a detection device, an air intake guide device, a navigation device, and a control system;

[0050] Furthermore, the chassis includes a frame 11, a battery, a drive motor 12, and tires 13. The battery is mounted on the frame 11, and the tires 13 are connected to the frame 11 via the drive motor 12. To ensure the vehicle has sufficient power to adapt to different environments and working conditions, this embodiment selects a 4-motor drive. Since most modern factories use integrated assembly lines, and the production environment is flat, the requirements for the patrol vehicle's steering and off-road capabilities are relatively low. Considering reducing equipment costs, lowering equipment failure rates, and improving hardware stability, the servo motor and independent suspension structure can be omitted, and the patrol vehicle controls its steering through differential rotation.

[0051] The detection device includes a chamber 21, a fan 22, a partition 23, and a sensor assembly. The chamber 21 is rectangular with an internal cavity, an air inlet at the front end, and an air outlet at the rear end. The chamber 21 is mounted on a chassis. The partition 23 is connected to the air outlet at the rear end of the chamber 21 and has air vents. The fan 22 is connected to the air inlet at the front end of the chamber 21. The sensor assembly is installed inside the chamber 21. The large air inlet and the fan 22 enable a wide range of air collection, which greatly increases the detection range. The collected air enters the cavity and is detected by the sensor assembly inside the cavity. The gas is blocked by the partition 23, which increases the residence time of the gas in the cavity, allowing the gas to be fully detected.

[0052] The sensor assembly includes a smoke sensor 24, a combustible gas detection sensor 26, and a toxic gas detection sensor 27. The smoke sensor 24, temperature sensor 25, combustible gas detection sensor 26, and toxic gas detection sensor 27 are connected to the inside of the cabin 21. These sensors are communicatively connected to the control system. The smoke sensor 24 uses an MQ135 gas sensor, and the temperature sensor 25 uses a DHT11 smoke sensor.

[0053] The control system is mounted on top of the chamber 21. The control system includes a controller 50, with a heat dissipation vent for the controller 50 located on the top of the chamber 21. The controller 50 is mounted at the heat dissipation vent. The control system also includes a housing for the controller 50, which is connected to the heat dissipation vent on the outside of the chamber 21. The control system also includes a display, which is connected to the controller 50. The controller 50 uses an STM32 microcontroller as its core microprocessor and implements gas concentration detection and monitoring, with automatic alarm for excessively high concentrations, through external hardware.

[0054] The air intake guide device is installed at the air intake, located at the front end of the fan 22. The air intake guide device includes a guide assembly, which includes a guide frame 31 and a guide plate 32. There are two or more guide plates 32, which are inclinedly connected inside the guide frame 31 and are parallel to each other. While the large air intake and the large fan 22 increase the air intake, other impurities may be sucked in. The air intake guide device can prevent garbage (such as plastic bags) and large dust particles from being sucked into the wall, thereby improving the reliability and stability of the equipment and enhancing its environmental adaptability.

[0055] The airflow guiding assembly also includes a power cylinder. The airflow guide plate 32 of the airflow guiding device is rotatably connected inside the airflow guide frame 31. One end of the power cylinder is connected to the airflow guide plate 32, and the other end is connected to the cabin 21. The power cylinder is communicatively connected to the control system. The opening and closing of the airflow guide plate 32 is controlled by the power cylinder, which can control the air intake angle and air intake volume. In harsh air environments (with a large amount of dust and debris), the angle of the airflow guide plate 32 can be increased to reduce the amount of debris entering the cabin 21, contaminating the sensors, and causing sensor misjudgments. When the patrol vehicle is not in use, the airflow guide plate 32 can be closed to protect the internal sensors from dust contamination.

[0056] The patrol vehicle for detecting hazardous gas leaks also includes an exhaust deflector, which is installed at the inlet and outlet, at the rear end of the partition 23. The exhaust deflector includes a deflector assembly, which controls the direction of the exhaust airflow to prevent the airflow from blowing towards the ground and causing dust. When the patrol vehicle is not in use, the deflector 32 can be closed to protect the internal sensors from dust contamination.

[0057] The navigation device is mounted at the front of the chassis. The navigation device includes a TCRT5000 infrared reflection sensor module 40, which is connected to the control system. The TCRT5000 infrared reflection sensor is a digital sensor whose infrared emitting diode continuously emits infrared light. When the emitted infrared light is not reflected back (or reflected back but with low intensity), the phototransistor remains off, and the indicator LED is off. At this time, the module outputs a high level. When the emitted infrared light is reflected back with sufficient intensity, the phototransistor reaches saturation, the indicator LED is charged, and the module outputs a low level.

[0058] The patrol vehicle sent to detect hazardous gas leaks also includes an alarm light 60 and a buzzer 70, which are respectively installed on the cabin 21. The alarm light 60 and the buzzer 70 are connected to the control system.

[0059] The patrol vehicle, equipped with a chassis, navigation device, and control system, enables automatic inspection of hazardous gas leaks. A large air intake and fan 22 facilitate wide-range air collection, significantly increasing the detection range. The collected air enters the cavity and is detected by sensor components within the cavity. The gas's residence time within the wall is increased by the baffle 23, ensuring thorough detection. The inclined design of the guide plate 32, combined with the increased air intake, prevents debris (such as plastic bags) and large dust particles from being sucked into the wall, improving the equipment's reliability, stability, and environmental adaptability.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
