[0029] The utility model provides Figure 1 The multiple chemical gas detection instrument shown includes an instrument body 1 and also includes:
[0030] The regulating mechanism 2 is arranged at one end of the interior of the instrument body 1 and is used to store and extend the air intake part and the air exhaust part of the instrument body 1;
[0031] The detection mechanism 3 is disposed inside the instrument body 1 and is used to detect the chemical gas entering into the instrument body 1 .
[0032] In order to conveniently store the intake pipe 206 and the exhaust pipe 208, Figure 2 and Figure 4 As shown, the adjustment mechanism 2 includes a rotating shaft 201, which is arranged on the inner wall of one end of the instrument body 1, and a servo motor 202 is arranged at one end of the rotating shaft 201. A rotating plate 203 is fixedly sleeved on the outer side of the other end of the rotating shaft 201, and traction plates 204 are rotatably installed on both sides of the outer wall of the end of the rotating plate 203 away from the rotating shaft 201. Fixed sleeve plates 205 are rotatably installed on the ends of the two traction plates 204 away from the rotating plate 203. An air inlet pipe 206 is fixedly inserted into the inner wall of the top fixed sleeve plate 205, and a collecting bucket 207 is fixedly installed on the top of the air inlet pipe 206. An exhaust pipe 208 is fixedly inserted into the inner wall of the bottom fixed sleeve plate 205. The servo motor 202 rotates the rotating shaft 201 when it works, and then the rotating plate 203 rotates. Under the traction of the traction plate 204, the distance between the two fixed sleeve plates 205 can be adjusted, so that the air inlet pipe 206 and the exhaust pipe 208 can be conveniently extended or stored.
[0033] In order to conveniently detect chemical gases, Figure 2 and Figure 5 As shown, the detection mechanism 3 includes a gas cylinder 301, which is arranged inside the instrument body 1, and a telescopic hose 302 is fixedly installed on the top and bottom inner walls of one end of the gas cylinder 301, the top telescopic hose 302 is fixedly connected to the bottom of the intake pipe 206, and the bottom telescopic hose 302 is fixedly connected to the top of the exhaust pipe 208, and a mounting plate 303 is arranged on the top of the other end of the gas cylinder 301, an electric cylinder 304 is arranged on the top of the mounting plate 303, and a plurality of infrared detection probes 305 extending into the gas cylinder 301 are fixedly installed on the bottom of the mounting plate 303, and the chemical gas enters the gas cylinder 301, and the composition and concentration of the chemical gas can be detected by the infrared detection probe 305.
[0034] In order to prevent external dust from entering the air inlet pipe 206 and the exhaust pipe 208, Figure 2 and Figure 3 As shown, the instrument body 1 includes a fixed shell 101, an operation panel 102 is fixedly installed on one side of the fixed shell 101, and traction belts 103 are fixedly installed on the top and bottom of the outer wall of one end of the fixed shell 101, and sealing plates 104 are fixedly installed on the ends of the two traction belts 103 away from the outer wall of the fixed shell 101, the top sealing plate 104 is arranged on the top of the collecting bucket 207, and the bottom sealing plate 104 is arranged on the bottom of the exhaust pipe 208. The operation of the adjustment mechanism 2 and the detection mechanism 3 can be controlled by the operation panel 102, and the air inlet end of the air inlet pipe 206 and the air outlet end of the exhaust pipe 208 can be closed by the sealing plate 104 to prevent dust from entering.
[0035] In order to provide power for the extension or retraction of the intake pipe 206 and the exhaust pipe 208, as Figure 2 As shown, the inner wall of one end of the fixed shell 101 is rotatably connected to the rotating shaft 201, and the outer wall of one end of the fixed shell 101 is fixedly connected to the servo motor 202. The servo motor 202 and the rotating shaft 201 are connected through an output shaft transmission. The fixed shell 101 can install the rotating shaft 201 and the servo motor 202. The servo motor 202 works to make the rotating shaft 201 rotate, and then under the traction action of the rotating plate 203 and the traction plate 204, the intake pipe 206 and the exhaust pipe 208 can be driven to extend or retract.
[0036] In order to facilitate the installation and removal of the infrared detection probe 305, Figure 2 and Figure 5 As shown, one end of the top inner side of the fixed shell 101 is fixedly connected to the electric cylinder 304, and the output end of the electric cylinder 304 is fixedly connected to the top of the mounting plate 303. The fixed shell 101 can install and fix the electric cylinder 304. The operation of the electric cylinder 304 causes the mounting plate 303 to move upward, thereby allowing the infrared detection probe 305 to be taken out from the inside of the gas cylinder 301, which can facilitate the staff to install and replace the infrared detection probe 305.
[0037] In order to keep the gas cylinder 301 stable inside the fixed housing 101, Figure 2 and Figure 5 As shown, the inner wall of the fixed shell 101 is fixedly connected to the outer walls of both ends of the gas cylinder 301 , the outer diameter of the gas cylinder 301 is the same as the inner wall width of the fixed shell 101 , and the fixed shell 101 can install and fix the gas cylinder 301 .
[0038] The specific implementation method is as follows: when detecting chemical gases, the servo motor 202 is controlled by the operation panel 102 to work, so that the rotating shaft 201 rotates, which can drive the rotating plate 203 to rotate, and then under the traction of the two traction plates 204, the two fixed sleeve plates 205 can be driven to move toward the top and the bottom, so that the air intake pipe 206 can be driven to extend upward, and at the same time, the exhaust pipe 208 can be extended toward the bottom of the fixed shell 101, and the two sealing plates 104 can be pushed to move away from the fixed shell 101 through the extension of the collecting bucket 207 and the exhaust pipe 208, so that the air intake pipe 206 and the exhaust pipe 208 can be extended out, and the chemical gas can be sucked into the gas storage cylinder 301 through the collecting bucket 207 and the air intake pipe 206, and then detected by the infrared detection probe. 305 can detect the composition and concentration of the chemical gas inside the gas cylinder 301, and can be displayed on the display screen on the surface of the operation panel 102. When the detection is completed, the exhaust pipe 208 can work to fully discharge the chemical gas inside the gas cylinder 301, and then the servo motor 202 works in reverse, so that the air inlet pipe 206 and the exhaust pipe 208 can be stored in the fixed shell 101. By rotating the sealing plate 104, the air inlet end of the air inlet pipe 206 and the air outlet end of the exhaust pipe 208 can be sealed, which can prevent external dust from entering the inner wall of the air inlet pipe 206 and the exhaust pipe 208, thereby ensuring the cleanliness of the instrument and the accuracy of the detection results. This embodiment specifically solves the problem that the air inlet and air outlet ports of the detection instrument in the prior art are easily contaminated by the outside air, which will affect the accuracy of the detection results.
[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
