Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, and in particular to an environmental monitoring device. Background Technology

[0002] Existing mobile environmental monitoring devices face the following technical bottlenecks in complex terrain and multi-parameter collaborative monitoring scenarios:

[0003] (1) The detection parameters are limited. Existing mobile environmental detection devices are limited by the split sensor architecture design. They usually only have built-in basic environmental parameter acquisition modules, such as temperature, humidity and particulate matter sensors. The detection of polluting gases such as CO2 and SO2 requires external detection terminals, which leads to the problem of poor spatiotemporal consistency of multi-source data due to the sequential contact of each detection device with the detection environment.

[0004] (2) There is interference between various sensors and battery modules, and there is a lack of effective physical isolation and electromagnetic shielding design;

[0005] (3) Terrain adaptability restricts detection accuracy. When wheeled equipment travels on bumpy terrain, the vibration is transmitted to the sensor module, causing distortion of the data collected by the noise sensor and turbulence of the gas sampling airflow of the gas sensor.

[0040] It should be noted that in this embodiment, "adaptation" means that the size and shape of the shielding layer 3 are the same as or slightly larger than the top opening of the base 21, so as to avoid a large gap between the shielding layer 3 and the top of the base 21 after the shielding layer 3 is installed on the top of the base 21.

The first driven wheel 13 and the second driven wheel 14 are rotatably mounted on the side wall of the battery compartment 2. The second driven wheel 14 is rotatably connected to the support frame 17. The third driven wheel 15 is fixedly connected to the support frame 17. The track 16 is circumferentially wound around the drive wheel 12, the first driven wheel 13, the second driven wheel 14, and the third driven wheel 15. The other end of the shock-absorbing spring 5 is fixedly connected to the third driven wheel 15.

[0051] The advantages of adopting the above preferred scheme are: the drive motor is conducive to driving the drive wheel to rotate, and the first driven wheel, the second driven wheel and the third driven wheel are conducive to transmitting the power of the drive wheel to the track, thereby driving the track to move on the ground.

[0052] Preferably, the first driven wheel 13 is rotatably sleeved on one end of the first rotating shaft, and the other end of the first rotating shaft is fixedly installed on the side wall of the battery compartment 2.

[0053] The advantage of adopting the above preferred scheme is that the first rotating shaft helps to provide support for the rotation of the first driven wheel.

[0054] Preferred, such as Figure 1 As shown, the second driven wheel 14 is rotatably sleeved on one end of the second rotating shaft 141, the third driven wheel 15 is rotatably sleeved on one end of the third rotating shaft 151, the support frame 17 is rotatably sleeved on the other end of the second rotating shaft 141, the second rotating shaft 141 is fixedly connected to the other side wall of the battery compartment 2, the support frame 17 is fixedly sleeved on the other end of the third rotating shaft 151, and the other end of the shock-absorbing spring 5 is fixedly connected to the side wall of the third rotating shaft 151.

[0056] The advantages of adopting the above preferred solution are: the support frame is rotatably sleeved on the other end of the second rotating shaft, and the support frame is fixedly sleeved on the other end of the third rotating shaft, which is beneficial to allow the support frame and the third rotating shaft to rotate around the second rotating shaft when subjected to external impact, thereby compressing the shock absorber spring and reducing the vibration amplitude and impact force generated when driving on bumpy terrain.

[0057] Preferably, the outer circumferential surface of the track 16 is provided with anti-slip texture, and the track 16 is made of rubber.

[0058] The advantages of adopting the above-mentioned preferred solution are: the anti-slip texture helps to enhance the friction of the track when it is moving; the rubber material not only helps to enhance the friction of the track when it is moving, but also helps to reduce shock and buffer; together with the shock-absorbing spring, it reduces the vibration and impact generated when driving on bumpy terrain, and avoids the distortion of collected data and the disturbance of sampling airflow.

[0059] The working process of this embodiment is described below:

[0060] like Figures 1 to 4 As shown, the user remotely starts the drive motor 11 through the controller, so that the tracked walking mechanism 1 carries the battery compartment 2, shielding layer 3, detection compartment 4 and shock absorber spring 5 to the environment to be detected. In this process, the shock absorber spring 5 works with the tracked walking mechanism 1 to reduce the vibration generated when traveling on bumpy terrain, and avoids the distortion of collected data, turbulence of sampling airflow and other situations.

The shielding layer 3 is located between the detection chamber 4 and the battery chamber 2, which helps to prevent mutual interference between the various sensors in the detection chamber 4 and the battery pack 22 in the battery chamber 2 during the detection process, thus improving detection accuracy and reliability.
