Description
Technical Field
[0001] This utility model relates to the field of detection device technology, specifically to an external gas source pollution detection device. Background Technology
[0002] Ozone, as a highly efficient oxidant, is widely used in water treatment, air purification, food processing, and medical sterilization. For example, in drinking water treatment, ozone can effectively degrade organic matter and inactivate bacteria and viruses; in food processing plants, ozone is used for space sterilization to meet hygiene standards. However, the quality of the gas source for an ozone generator directly affects its ozone generation efficiency and equipment stability.
[0003] Currently, in existing technologies, some detection devices lack filtration of the gas source when it enters the detection device. Impurities can easily damage the detection probe, increasing the maintenance cost of the device. At the same time, the lack of sealing of the air inlet when the gas source enters the detection device can lead to gas leakage during the detection process, allowing external gas to re-enter and affecting the accuracy of the detection results. Therefore, an external gas source pollution detection device is proposed. Utility Model Content
[0004] The main objective of this invention is to provide an external gas source pollution detection device that can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention proposes an external gas source pollution detection device, comprising a housing, a fixing plate fixedly connected to the top of the housing, an air inlet on the top of the fixing plate, an opening and closing assembly for detecting gas entering the housing on the outer wall of the fixing plate, a sealing assembly for sealing after gas enters the air inlet on the inner side of the air inlet, a gas source detector mounted on the outer wall of the housing, and a detection probe at one end of the gas source detector located inside the housing. The opening and closing assembly includes:
[0006] A circular groove is formed on the outer wall of the fixed plate, and a straight groove is formed on the inner wall of the circular groove;
[0007] A knob is movably fitted to the top of a fixed plate. A rotating shaft is fixedly connected to the inner wall of the knob, and the rotating shaft movably passes through the fixed plate and extends downward.
[0008] A turntable is fixedly connected to the extension end of a rotating shaft. A curved groove is formed on the outer wall of the turntable, and a connecting rod is slidably connected to the inner wall of the curved groove. A sealing plate is fixedly connected to the end of the connecting rod away from the curved groove.
[0009] Preferably, the connecting rod is slidably connected to the inner wall of the straight groove, and one end of the connecting rod is slidably connected to the inner wall of the curved groove.
[0010] Preferably, the sealing assembly includes an air chamber, which is fixedly connected to the inner wall of the air inlet. A piston rod is movably connected to the inner wall of the air chamber. One end of the piston rod movably passes through one side of the air chamber and extends outward. A push block is fixedly connected to the extended end of the piston rod. A piston block is fixedly connected to the end of the piston rod away from the push block. The piston block is elastically connected to the inner wall of the air chamber by a spring. An air pipe is connected to the side of the air chamber away from the push block. A sealing ring is connected to one end of the air pipe.
[0011] Preferably, the sealing ring is installed on the inner wall of the housing, and the sealing ring and the sealing plate are located on the same horizontal plane.
[0012] Preferably, an alarm is installed on the outer wall of the gas source detector. When the alarm detects that the gas pollution level exceeds a set threshold, it will sound an alarm to remind relevant personnel to pay attention.
[0013] Preferably, the number of gas source detectors is three, and the three gas source detectors are arranged in a circumferential array around the center of the housing.
[0014] Preferably, a filter plate is fixedly connected to the inner wall of the housing. The filter plate is honeycomb-shaped and can perform preliminary filtration of the incoming gas to remove larger impurity particles, thereby preventing impurities from damaging the detection probe or affecting the accuracy of the detection results.
[0015] This utility model provides a device for detecting pollution in an externally supplied gas source. It has the following beneficial effects:
[0016] (1) The external gas source pollution detection device realizes the control of the gas source entry through the opening and closing component. When the knob is turned to open the air inlet, the gas enters the housing. The larger impurity particles in the gas are filtered through the filter plate first, and then the pollutant parameters are monitored in real time through the multi-directional detection probe. When the gas pollution level exceeds the threshold, the alarm will sound an alarm in time, so that relevant personnel can respond and handle it quickly.
[0017] (2) When the external gas source pollution detection device closes the air inlet by rotating the knob, the connecting rod will push the push block to drive the piston block to compress the gas in the gas chamber, so that the sealing ring expands to fill the gap between the sealing plate and the inner wall of the shell, effectively preventing the gas leaking and making the detection results more stable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-6This utility model proposes an external gas source pollution detection device, including a housing 1, a fixing plate 2 fixedly connected to the top of the housing 1, an air inlet 3 on the top of the fixing plate 2, the number of air inlets 3 is six, the six air inlets 3 are arranged in a circular array around the center of the fixing plate 2, the outer wall of the fixing plate 2 is provided with an opening and closing component 4 for detecting the gas source entering the housing 1, the inner side of the air inlet 3 is provided with a sealing component 5 for sealing after the gas source enters, and a gas source detector 6 is installed on the outer wall of the housing 1.
[0030] In an embodiment of this utility model, for the purpose of detecting the external gas supply source, the opening and closing component 4 specifically includes a circular groove 41, a knob 43, and a turntable 45. The circular groove 41 is formed on the outer wall of the fixed plate 2, and a straight groove 42 is formed on the inner wall of the circular groove 41. The knob 43 is movably attached to the top of the fixed plate 2, and a rotating shaft 44 is fixedly connected to the inner wall of the knob 43. The rotating shaft 44 movably passes through the fixed plate 2 and extends downward. The turntable 45 is fixedly connected to the extension end of the rotating shaft 44. A curved groove 46 is formed on the outer wall of the turntable 45, and a connecting rod 47 is slidably connected to the inner wall of the straight groove 42. One end of the connecting rod 47 is slidably connected to the inner wall of the curved groove 46, and a sealing plate 48 is fixedly connected to the end of the connecting rod 47 away from the curved groove 46.
[0031] Furthermore, the sealing assembly 5 includes an air chamber 51, which is fixedly connected to the inner wall of the air inlet 3. A piston rod 52 is movably connected to the inner wall of the air chamber 51. One end of the piston rod 52 movably passes through one side of the air chamber 51 and extends outward. A push block 53 is fixedly connected to the extended end of the piston rod 52. A piston block 54 is fixedly connected to the end of the piston rod 52 away from the push block 53. The piston block 54 is elastically connected to the inner wall of the air chamber 51 by a spring. An air pipe 55 is connected to the side of the air chamber 51 away from the push block 53. A sealing ring 56 is connected to one end of the air pipe 55. The sealing ring 56 is installed on the inner wall of the housing 1. The sealing ring 56 and the sealing plate 48 are located on the same horizontal plane. The sealing assembly 5 has a structure of three sets, and the three sets of sealing assemblies 5 are located in the three air inlets 3.
[0032] Furthermore, a detection probe 7 is provided at one end of the gas source detector 6 located inside the housing 1. An alarm 8 is installed on the outer wall of the gas source detector 6. When the gas pollution level is detected by the alarm 8 to exceed the set threshold, an alarm will be sounded to remind relevant personnel to pay attention. There are three gas source detectors 6, which are arranged in a circular array with the center point of the housing 1 as the center. A filter plate 9 is fixedly connected to the inner wall of the housing 1. The filter plate 9 is honeycomb-shaped and can perform preliminary filtration on the incoming gas to remove larger impurity particles and avoid impurities from damaging the detection probe 7 or affecting the accuracy of the detection results.
[0033] In this invention, when the gas source needs to be tested, the operator rotates knob 43. Rotation of knob 43 causes shaft 44 to rotate synchronously, causing turntable 45 to rotate around the central axis of fixed plate 2. As turntable 45 rotates, the trajectory of curved groove 46 guides connecting rod 47 to slide within straight groove 42. This movement of connecting rod 47 causes sealing plate 48 to move synchronously, opening air inlet 3. At this time, air inlet 3 on fixed plate 2 is simultaneously opened, allowing external gas to enter the housing 1 through air inlet 3. After the gas has entered, knob 43 is rotated in the opposite direction, causing connecting rod 47 to abut against push block 53. This causes piston block 54 to push the gas in gas chamber 51. The gas is transmitted through gas pipe 55 to sealing ring 56. Sealing ring 56 expands and fills the gap between sealing plate 48 and the inner wall of housing 1, thus completing the gas seal and making the testing structure more efficient. Accurately, as the gas inside the housing 1 flows towards the detection area, it first passes through the filter plate 9 for preliminary filtration, removing larger impurity particles to prevent damage to the detection probe 7 or affecting the accuracy of the detection results. The filtered gas then enters the detection area inside the housing 1 and comes into full contact with the gas through the gas source detector 6 located inside the housing 1 and the detection probe 7. The detection probe 7 monitors and analyzes parameters such as the composition and concentration of pollutants in the gas in real time. When the gas source detector 6 determines that the degree of gas pollution exceeds the preset threshold, it will control the alarm 8 to sound an alarm to remind relevant personnel to take timely measures to treat the polluted gas source.
[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
