[0002] With the acceleration of the industrialization and urbanization processes, the problem of environmental gas pollution has become increasingly prominent, and the demand for real-time monitoring of toxic and harmful gases (such as CO, SO2, NO x , VOCs, etc.) has increased significantly. Traditional environmental gas detection devices are usually realized through fixed sensors or portable devices, but there are still many technical bottlenecks in actual applications: Existing fixed gas detection devices mostly adopt wall-mounted or pole-mounted installation methods, which require professional personnel for wiring, fixing, and debugging. Deploying in complex environments (such as high altitudes, narrow spaces, or temporary monitoring points) is time-consuming and laborious. In addition, traditional devices have high requirements for the flatness of the installation base, and additional brackets or auxiliary structures need to be configured in non-standard scenarios, further increasing the installation cost and difficulty: At the same time, different detection probes are required for detecting different harmful and toxic gases.

The guide strip drives the gas to rotate and generate centrifugal force, causing the dust to move to the inner wall of the intake pipe and separating the dust and gas through the air distribution strip, so that the filtered air contacts the detection probes to detect harmful gases inside them.

[0021] Referring to the attached Figures 1-7 , an easily installed ambient gas detection device, comprising a base structure 1, an installation chamber structure 2 is arranged on the outer wall of the base structure 1, a gas guiding structure 3 is arranged on the outer wall of the installation chamber structure 2, a dust removal structure 4 is rotatably connected inside the gas guiding structure 3, a driving gear 5 is arranged on one side of the base structure 1, the number of the gas guiding structures 3 is set to be multiple, a filtering structure 6 is rotatably connected to the outer walls of the multiple gas guiding structures 3, the filtering structure 6 meshes with the driving gear 5, and a detection probe 7 is arranged inside the gas guiding structure 3; The base structure 1 includes a base body 101, guiding grooves 106 are formed on both sides of the base body 101, sliders 107 are slidably connected inside the guiding grooves 106, a return spring 108 is arranged between the guiding grooves 106 and the sliders 107, a limiting block 109 is arranged at the top of the return spring 108, a first installation groove 102 and a second installation groove 103 are formed inside the base structure 1, conductive columns 104 are arranged on the inner walls of the first installation groove 102 and the second installation groove 103, positioning tubes 105 are arranged at the bottoms of the conductive columns 104, and the bottoms of the positioning tubes 105 are threadedly connected to the guiding grooves 106. When it is necessary to install the ambient gas detection device inside the factory building, the base body 101 is contacted with the wall of the factory building and fixed by bolts, then the circuit is connected to the positioning tube 105 at the bottom of the base body 101 and the bolts are rotated to connect the bolts with one end of the wire. At the same time, a storage battery and a miniaturized integrated chip are also arranged inside the base body 101, and the two are electrically connected. The storage battery is used for temporary power supply. The miniaturized integrated chip integrates a sensor, a processor, a communication module, and a multi-mode wireless transmission module into a single chip through MEMS microelectromechanical system technology. The multi-mode wireless transmission module can be selected according to the specific environment of the factory building; short distance: LoRa, ZigBee with low power consumption, suitable for networking inside the factory area; Wide area network: NB-IoT, 4G / 5G with wide coverage range, supporting remote monitoring; Satellite communication: suitable for emergency monitoring in remote areas without base station coverage; After that, the installation bin structure 2 is installed on the outer wall of the base structure 1.

[0022] Furthermore, for the installation bin structure 2, it includes an installation base 201 disposed on the inner wall of the base body 101. A conductive groove 202 is opened at the bottom of the installation base 201, and the conductive groove 202 is in contact with the conductive column 104. A detection housing 203 is provided at the top of the installation base 201. An air outlet bin 204 is opened in the middle of the detection housing 203. A separation plate 205 is arranged inside the detection housing 203. The number of the separation plates 205 is set to be multiple, and the multiple separation plates 205 are annularly arrayed inside the detection housing 203. A cavity is formed between two separation plates 205. Air guide bins 207 are opened on both sides of the inner wall of the detection housing 203. The air guide bin 207 inside the detection housing 203 is connected to the air outlet bin 204. A threaded pipe 206 is opened at the top of the detection housing 203. Different detection probes 7 can be installed inside the detection housing 203 according to the environment of the factory building, and the detection probe 7 is threadedly connected to the threaded pipe 206. The threaded pipe 206 is electrically connected to the air outlet bin 204. After the detection probe 7 is installed, the installation base 201 and the detection housing 203 are connected, and then the installation base 201 is placed inside the base body 101, so that the return spring 108 pushes the limit block 109 to slide on the inner wall of the guiding groove 106, and then the bottom of the limit block 109 is in contact with the top of the installation base 201 to fix the position of the installation base 201.

[0023] Furthermore, for the air guiding structure 3, it includes an air inlet pipe 301. One end of the air inlet pipe 301 is connected to the air guide bin 207 outside the detection housing 203. A gas distribution strip 302 is arranged inside the air inlet pipe 301. Blocking strips 303 are arranged at the top and bottom of the gas distribution strip 302. The blocking strip 303 at the top of the gas distribution strip 302 is connected to the air inlet pipe 301. A diversion hole 304 is opened in the middle of the blocking strip 303 at the bottom of the gas distribution strip 302. An ash discharge pipe 305 is arranged at the bottom of the air inlet pipe 301. The air is driven by the guiding strip 404 to generate a centrifugal force, so that the dust inside the air moves to the outside, reducing the dust content in the air near the rotating barrel 403. After that, the air passes through the gas distribution strip 302, and the gas distribution strip 302 shunts the inner and outer layer of air. The inner layer of air enters the inside of the detection housing 203 through the blocking strip 303, and the outer layer of air is discharged through the ash discharge pipe 305, thus solving the problem of dust accumulation in the sampling pipeline, reducing the gas flow efficiency, and even completely blocking the sampling, resulting in distorted detection values or equipment failures. At the same time, it can also avoid that some components in the dust, such as metal oxides and organic substances, may react non-specifically with the target gas to generate false signals. For example: Iron-containing particles react with NO x to generate interfering compounds; VOCs are adsorbed on the surface of dust, resulting in the detected concentration being lower than the actual value.

[0024] Further, the dust removal structure 4 includes a rotating shaft 401. The rotating shaft 401 is rotatably connected to the inside of the intake pipe 301. One end of the rotating shaft 401 is provided with a driving fan blade 402, and the other end of the rotating shaft 401 is provided with a rotating barrel 403. The outer wall of the rotating barrel 403 is provided with guide strips 404. The number of the guide strips 404 is set to be multiple, and the multiple guide strips 404 are annularly arrayed on the outer wall of the rotating barrel 403. The guide strips 404 are spiral. One end of the rotating barrel 403 is provided with a guide cone 405, and the guide cone 405 is conical. When the driving fan blade 402 is started, the driving fan blade 402 rotates to draw external air into the inside of the intake pipe 301. At the same time, the driving fan blade 402 drives the rotating shaft 401 to rotate. The driving fan blade 402 drives the rotating barrel 403 to rotate inside the intake pipe 301. The rotating barrel 403 drives the guide strips 404 on the outer wall to rotate, and the guide strips 404 drive the aligned air inside the intake pipe 301 to rotate, causing the gas to generate centrifugal force. Then the gas enters the cavity inside the detection housing 203 through the diversion holes 304 and is detected by the detection probe 7. The gas after detection enters the inside of the air outlet chamber 204 through the air guide chamber 207 and is discharged.

[0025] Further, the filtering structure 6 includes a filtering baffle 602 provided on the outer wall of a rotating ring 601. Meshing tooth rings 603 are provided at the top and bottom of the rotating ring 601. The meshing tooth rings 603 are engaged with a driving gear 5. One end of the driving gear 5 is provided with a motor, and the motor is connected to the base body 101. When the motor is started, the motor drives the driving gear 5 to rotate. The driving gear 5 drives the rotating ring 601 to rotate on the outer wall of the intake pipe 301 through the meshing tooth rings 603. Then the intake pipe 301 is aligned with the filtering baffle 602, so that the air inside the factory building can enter the inside of the air guiding structure 3 through the filtering baffle 602 for preliminary filtering and then enter the inside of the installation chamber structure 2, pass through the detection probe 7 and be discharged.

[0026] In this application, the provided filtering baffle 602 can effectively intercept particles above PM10 in the air, and at the same time seal the intake pipe 301 when the rotating ring 601 is aligned with the intake pipe 301; When the provided air guiding structure 3 and dust removal structure 4 cooperate with each other to introduce air, the dust-containing gas enters from the intake pipe 301 at high speed, forms a vortex along the intake pipe 301 by rotation. The particulate matter is thrown towards the intake pipe 301 under the action of centrifugal force and is discharged through the ash discharge pipe 305 along the intake pipe 301. The purified gas is discharged from the diversion holes 304.

[0027] Applicable scenarios: Applicable to particles with a separation particle size > 5 μm.

[0028] The above-described embodiments merely represent certain implementation manners of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
