Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a toxic gas detection device with an anti-adhesion structure. Background Technology

[0002] A toxic gas detection device is a device used to monitor and identify the presence of toxic gases in the environment. Its core function is to detect the concentration of toxic gases in the air within a specific area in real time or periodically, and to issue an alarm or take other safety measures when the concentration exceeds a safety threshold.

[0003] Existing toxic gas detection devices typically lack automated cleaning mechanisms and require regular manual cleaning. This can lead to untimely or incomplete cleaning, making it easy for foreign matter and dust to accumulate inside the detection device, thus affecting detection accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a toxic gas detection device with an anti-adhesion structure. This device prevents a large amount of foreign matter and dust from adhering inside the detection device, thus solving the problem of foreign matter and dust easily adhering inside the detection device in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A toxic gas detection device with an anti-adhesion structure includes a housing, a protrusion fixedly connected to the side wall of the housing by bolts, an installation tube fixedly connected to the side wall of the protrusion, a detection head disposed inside the housing, the detection head being fixedly connected to the end of the installation tube, and an air inlet pipe being fixedly connected through the lower end of the housing; a rotating base rotatably disposed on the inner wall of the upper end of the housing, two electric actuators fixedly connected to the upper end of the rotating base, a ring plate slidably connected inside the lower end of the rotating base, the output end of the electric actuators being fixedly connected to the upper end of the ring plate, a chamber disposed inside the ring plate, multiple holes disposed on the outer wall of the ring plate, and multiple slots disposed on the inner wall of the ring plate, all of which communicate with the chamber.

[0007] Preferably, the detector body is fixedly connected to the side wall of the housing, and a connecting line is fixedly connected between the connecting end of the detector body and the connecting end of the detection head, the connecting line being located inside the mounting tube.

[0008] Preferably, a motor is fixedly connected to the upper end of the housing, and a gear is rotatably connected inside the side wall of the housing, with the upper end of the gear fixedly connected to the output end of the motor.

An air pump is fixedly connected to the upper end of the rotating base, and the output end of the air pump is connected to the inside of the cavity.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A toxic gas detection device with an anti-adhesion structure includes a housing 001. A protrusion 102 is bolted to the side wall of the housing 001, and an installation tube 103 is fixedly connected to the side wall of the protrusion 102. A detection head 104 is disposed inside the housing 001 and fixedly connected to the end of the installation tube 103. An air inlet pipe 105 is fixedly connected to the lower end of the housing 001. A rotating base 002 is rotatably mounted on the upper inner wall of the housing 001. Two electric actuators 202 are fixedly connected to the upper end of the rotating base 002, and a ring plate 203 is slidably connected to the lower inner end of the rotating base 002. The output ends of the electric actuators 202 are connected to the ring plate 202. 3. The upper end is fixedly connected. A chamber 204 is provided inside the ring plate 203. Multiple holes 205 are provided on the outer wall of the ring plate 203, and multiple slots 206 are provided on the inner wall of the ring plate 203. Both the slots 206 and the holes 205 are connected to the chamber 204. The holes 205 are inclined downwards, and the slots 206 are inclined upwards. The naturally flowing gas enters the interior of the housing 001 through the air inlet pipe 105, and then flows out through the central hole of the rotary seat 002. During this process, the detection head 104 detects toxic substances in the gas. After the gas flow and detection by the detection head 104 inside the housing 001 for a long time, As the rotary base 002 rotates, the output end of the electric actuator 202 pushes the ring plate 203 downwards. Cleaning fluid is supplied to the chamber 204 and sprayed out through multiple holes 205 and multiple slots 206. As the ring plate 203 gradually slides down and rotates, the cleaning fluid sprayed from the downward-sloping holes 205 flushes and cleans the inner wall of the housing 001. Simultaneously, the upward-sloping slots 206 flush and clean the side walls of the mounting tube 103 and the surface of the detection head 104 located inside the housing 001, preventing excessive residue from adhering to the surface of the detection head 104, the side walls of the mounting tube 103, and the inner wall of the housing 001. Foreign dust and debris can affect the detection results of the detection head 104. The cleaning solution is discharged through the air inlet pipe 105. After the surface of the detection head 104, the side wall of the mounting tube 103 and the inner wall of the housing 001 are rinsed, airflow is delivered into the chamber 204. The airflow is sprayed out through multiple holes 205 and multiple slots 206 to blow away the surface of the detection head 104, the side wall of the mounting tube 103 and the housing 001, so as to avoid excessive water stains adhering to the surface of the detection head 104, the side wall of the mounting tube 103 and the inside of the housing 001. At the same time, some of the airflow flows downward into the air inlet pipe 105 to blow out the water stains remaining inside the air inlet pipe 105.

[0023] The detector body 101 is fixedly connected to the side wall of the housing 001. A connecting wire is fixedly connected between the connecting end of the detector body 101 and the connecting end of the detection head 104. The connecting wire is located inside the mounting tube 103. The accurate transmission and processing of the detection signal is ensured through the connecting wire between the detector body 101 and the detection head 104, thereby realizing the effective detection of toxic gases. The detector body 101 adopts a Honeywell Sperian GD1 infrared (NDIR) gas detector. The detection end of this model of detector adopts a waterproof design. The detection head 104 corresponds to the detection end of this model of detector, thereby preventing water from entering the detection head 104 during the rinsing process.

[0024] A motor 106 is fixedly connected to the upper end of the housing 001, and a gear 107 is rotatably connected inside the side wall of the housing 001. The upper end of the gear 107 is fixedly connected to the output end of the motor 106, and the gear 107 is driven to rotate through the output end of the motor 106.

[0025] Multiple toothed blocks 201 are fixedly connected in a ring array on the side wall of the rotary seat 002. The toothed blocks 201 mesh with the gear 107. When the gear 107 rotates, the rotary seat 002 rotates through the cooperation between the gear 107 and the toothed blocks 201.

[0026] The upper end of the rotary seat 002 is fixedly connected to the housing 207. The lower end of the housing 207 is provided with a cavity 208. A connecting pipe 209 is provided between the cavity 208 and the chamber 204. Cleaning fluid or airflow is transported inside the cavity 208. The cleaning fluid or airflow inside the cavity 208 flows to the chamber 204 through the connecting pipe 209. The connecting pipe 209 is a telescopic pipe. One end of the connecting pipe 209 is fixedly connected to the lower end of the housing 207, and the other end of the connecting pipe 209 is fixedly connected to the upper end of the ring plate 203. The connecting pipe 209 and the rotary seat 002 are slidably connected through each other.

[0027] A water pump 210 is fixedly connected inside the housing 207. The output end of the water pump 210 is connected to the inside of the cavity 208. An air pump 211 is fixedly connected to the upper end of the rotary seat 002. The output end of the air pump 211 is connected to the inside of the cavity 208. The cleaning fluid inside the housing 207 is drawn through the input end of the water pump 210, and then the cleaning fluid is delivered to the inside of the cavity 208 through the output end of the water pump 210. A filter screen is provided at the input end of the air pump 211. The external airflow is drawn through the input end of the air pump 211, and the external airflow is filtered and purified through the filter screen. Then the air pump 211 delivers the external airflow to the inside of the cavity 208.

[0028] In this invention, naturally flowing gas enters the housing 001 through the air inlet pipe 105 and then flows out through the central hole of the rotary seat 002. During this process, the detection head 104 uses infrared (NDIR) detection technology to analyze the collected gas sample and detect whether it contains toxic gas components. During the detection process, the detection head 104 monitors the gas concentration in real time and converts the detection result into an electrical signal. The detection head 104 transmits the converted electrical signal back to the detector body 101 through the connecting line.

[0029] When the gas inside the housing 001 and the detection head 104 are guided to flow and detect for an extended period, the output of the motor 106 drives the gear 107 to rotate. The engagement between the gear 107 and the gear block 201 causes the rotary seat 002 to rotate. Simultaneously, the output of the electric push rod 202 pushes the ring plate 203 downwards, drawing the cleaning fluid from the housing 207 through the input of the water pump 210. The cleaning fluid is then delivered to the cavity 208 through the output of the water pump 210. Subsequently, the cleaning fluid flows through the connecting pipe 209 into the chamber 204 for cleaning. The cleaning fluid is sprayed out through multiple holes 205 and multiple slots 206. As the ring plate 203 gradually slides down and rotates, the cleaning fluid sprayed out by the downwardly inclined holes 205 flushes and cleans the inner wall of the housing 001. At the same time, the upwardly inclined slots 206 flush and clean the side wall of the mounting tube 103 and the surface of the detection head 104 located inside the housing 001, so as to avoid a lot of foreign matter and dust adhering to the surface of the detection head 104, the side wall of the mounting tube 103, and the inner wall of the housing 001. The cleaning fluid after cleaning is discharged through the air inlet pipe 105.

[0030] After the surface of the detection head 104, the side wall of the mounting tube 103, and the inner wall of the housing 001 are rinsed, the external airflow is drawn in through the input end of the air pump 211, and the external airflow is filtered and purified through the filter screen. Then the air pump 211 delivers the external airflow into the cavity 208. The airflow then flows into the cavity 204 through the connecting tube 209. The airflow is ejected through multiple holes 205 and multiple slots 206 to blow away the surface of the detection head 104, the side wall of the mounting tube 103, and the housing 001, so as to avoid excessive water stains adhering to the surface of the detection head 104, the side wall of the mounting tube 103, and the inside of the housing 001. At the same time, some of the airflow flows downward into the air inlet pipe 105 to blow out the water stains remaining inside the air inlet pipe 105.

[0031] After the surface of the detection head 104, the side wall of the mounting tube 103 and the inner wall of the housing 001 are flushed and purged, the ring plate 203 slides upward to the lower end of the rotating seat 002.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
