Embodiment 1

[0029] Embodiment 1, the fast-moving air quality detection non-power pumping air chamber, including the air chamber box body 1, the thickness of the air chamber box body 1 matches the distance between the trunk bracket on the car and the upper end of the car body, it is characterized in that the The upper end of the air chamber box body 1 is respectively provided with air inlets 2 symmetrically left and right. The air inlet ports 2 are relatively large. Chamber 3, the trapezoidal air inlet chamber 3 is installed in a right-angled trapezoidal shape, the front and rear are transparent, the trapezoidal air inlet 2 at the upper end is large, and the air outlet at the lower end is small, the small opening of the trapezoidal air inlet chamber 3 communicates with the corresponding air inlet 2, The box body 1 and two sets of trapezoidal air inlet chambers 3 form a U-shaped structure that matches the luggage rack bracket of the vehicle body, so that it can be stuck on the bracket of the...

Embodiment 2

[0032] Embodiment two, on the basis of embodiment one, because on the car bracket, the car runs faster, therefore, this device is only clamped on the car bracket by the first spring 5, and the slope of the trapezoidal air inlet chamber 3 The side faces the two sides of the air chamber box body 1, and the facing side is oppositely arranged. The trapezoidal air inlet chamber 3 is provided with a rectangular receiving groove 11 on the facing side wall, and a horizontally arranged trigger lever is vertically slidably connected in the receiving groove 11. 12. A tank structure is provided on the two front and rear side walls of the receiving tank 11, so that the trigger lever 12 is vertically slidably connected therein, and the trigger lever 12 is placed between two sets of trapezoidal air inlet chambers 3. The trigger lever 12 are respectively vertically connected with a rack 13 and a ratchet 14 placed in the receiving groove 11, the longitudinal interval between the rack 13 and the...

Embodiment 3

[0035] Embodiment 3, on the basis of Embodiment 1 or 2, two sets of solar auxiliary power supply devices are respectively installed on the side walls of the gas chamber box 1, and the solar auxiliary power supply devices include The solar panel 30 in the wall, the panel 30 is rotatably installed in the hidden groove opened in the side wall, the rotating shaft of the panel 30 is evenly distributed along the circumference and connected with four groups of frames 31 arranged in the radial direction, and also includes a fixed connection The fixed ring 32 on the side wall of the air chamber box body 1, a trigger pin 33 is slidably connected in the radial direction in the frame body 31, and a third spring 34 is connected between the trigger pin 33 and the inner bottom surface of the rectangular frame 6 , the fixed ring 32 is provided with four sets of limiting grooves 35 evenly distributed along the circumference, the limiting grooves 35 cooperate with the trigger pin 33 to realize t...

Abstract

The invention relates to a quick-moving unpowered air suction chamber for air quality detection, which adopts an air chamber structure detachably mounted on a luggage rack of a vehicle body, so that air is quickly conveyed into an air chamber box body through a Venturi effect along with the movement of the vehicle body, and then the concentration of each air is detected by a detection chip in the air chamber. The gas renewal speed is high, in the process of moving along with a vehicle body, the limiting rod is matched with the luggage rack through cooperation of the pawl and the ratchets, the device is reliably locked on the luggage rack, meanwhile, the device is further provided with a solar cell panel auxiliary power supply system, more energy is saved, the device is more environmentally friendly, and the device can be conveniently installed on the luggage rack of the vehicle body; and the measuring precision is high, the measured data quantity becomes large and dense, so that a large and dense detection network is formed, precise monitoring of the atmospheric concentration is achieved, the gas updating speed is high, redundant gas power is not needed, and the device can be reliably installed on a luggage rack, does not occupy space, is convenient to disassemble and install and is ingenious in structure.

Description

technical field [0001] The invention belongs to the technical field of gas detection equipment, and in particular relates to a fast-moving air quality detection non-power exhaust air chamber. Background technique [0002] With the rapid development of China's economy, the contradiction between economic development and environmental protection has become increasingly prominent. At present, the country has realized the importance of strengthening environmental supervision and ensuring environmental safety. Emergency monitoring is the technical support for environmental emergency response, and fast and accurate emergency monitoring data is helpful to help management departments respond to environmental emergencies scientifically. [0003] Therefore, following the requirements of sustainable development in the country, real-time monitoring of the environment is required. The detection technology of the existing technology adopts station-based detection methods, just like commun...
