Description
Technical Field
[0001] The utility model relates to the field of air quality detection, in particular to a multi-angle air quality detector. Background Art
[0002] Air quality testing refers to testing the quality of air. The quality of air reflects the concentration of pollutants in the air. Before working in semi-enclosed limited spaces such as underground pipelines and wells, it is necessary to ventilate first, and then use air quality detectors to test the composition and concentration of internal air pollutants. Workers can only go down to work after the internal air quality is lower than the warning value.
[0003] However, the structure of traditional air quality detectors still has certain shortcomings: currently, when conducting gas detection inside spaces such as underground wells and underground pipelines, workers usually extend a hose and draw the internal air into the detector for detection through a pump. This has two defects: first, the length of the pipeline cannot be seen clearly from the outside. If there is sewage at the bottom of the pipeline, the pump will easily draw the sewage into the hose. At the same time, the position of the hose cannot be controlled. When the hose is extended into the pipeline, if the pipe mouth is attached to the pipe wall, impurities attached to it will be sucked in, causing the instrument to malfunction. Secondly, the bottom of the manhole is connected to other underground pipelines, and a hose is inserted for detection. Since the angle cannot be adjusted for multi-directional detection, the detection accuracy is not high.
[0004] Therefore, it is necessary to provide a new multi-angle air quality detector to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem solved by the utility model is to provide a multi-angle air quality detector capable of performing multi-angle gas detection in semi-enclosed limited spaces such as underground pipelines and wells.
[0006] In order to solve the above technical problems, the utility model provides a multi-angle air quality detector comprising: a support seat, a small pulley is rotatably connected to the top side of the support seat, a fixing ring is fixedly connected to the surface of the support seat away from the small pulley, the top of the fixing ring is rotatably connected to the large pulley, a mounting frame is connected to the upper surface of the large pulley by bolts, a first motor is installed on the upper surface of the mounting frame, a gear is installed on the output end of the first motor, a vertical rod is slidably connected to the inside of the large pulley, a rack is fixedly connected to the surface of the vertical rod, the rack is vertically arranged and meshes with the gear, and the bottom of the vertical rod extends A fixing plate is fixedly connected to the bottom surface of the vertical rod and extends to the lower side of the fixing ring, a rotating plate is rotatably connected to the surface of the fixing plate, a telescopic cylinder is rotatably connected between the top of the rotating plate and the surface of the fixed plate, an air quality detection module is connected to the front wall surface of the rotating plate by bolts, a camera is installed on the rear wall surface of the rotating plate, a mounting plate is provided at the upper side of the support seat, a display screen is installed on one side wall surface of the mounting plate, a control module is installed on the upper surface of the support seat located on one side of the large pulley, and the first motor, telescopic cylinder, display screen, air quality detection module and camera are all electrically connected to the control module.
[0007] As a further solution of the utility model, a lighting lamp is installed on the surface of the rotating plate located on the upper side of the camera through a connecting block, and the lighting lamp is electrically connected to the control module.
[0008] Through the above technical scheme, when conducting gas detection inside spaces such as underground wells and underground pipelines, workers usually extend a hose and use a pump to draw the internal air into the detector for detection. This has defects. Since the length of the pipeline cannot be seen from the outside, if there is sewage at the bottom of the pipeline, the pump body will easily draw the sewage into the hose. At the same time, the position of the hose cannot be controlled. When the hose is extended into the pipeline, if the pipe mouth is attached to the pipe wall, impurities attached to it will be sucked in, causing the instrument to malfunction. The device installs the air quality detection module at the end of the rotating plate. The user can move the support seat above the manhole, and then extend the vertical rod into the manhole through the cooperation of the gear and rack, and turn on the camera and the light at the same time. The staff can view the situation inside the manhole through the display screen, which is convenient for adjusting the position of the air quality detection module at any time to detect the air composition in the underground limited space.
[0009] As a further solution of the utility model, a limiting groove is provided on the surface of the large pulley, the rack is located inside the limiting groove, and the top of the vertical rod is fixedly connected to a limiting plate.
[0010] Through the above technical solution, the position of the rack is limited by the limit groove to prevent the rack position from shifting and affecting the normal lifting of the structure. The limit plate installed on the top of the vertical rod can prevent the vertical rod from escaping from the inside of the large pulley.
[0011] As a further solution of the utility model, a belt is connected between the large pulley and the small pulley, a second motor is installed at the bottom of the small pulley, and the second motor is electrically connected to the control module.
[0012] Through the above technical solution, the bottom of the manhole is connected to other underground spaces. In the traditional structure, detection is carried out by inserting a hose. Since the angle cannot be adjusted for multi-directional detection, the detection accuracy is not high. In this device, when the air quality detection module reaches a suitable position, the telescopic cylinder is started to drive the rotating plate to adjust the angle, so that the end of the rotating plate moves to other underground spaces connected to the manhole, and then the small pulley is driven by the second motor. The small pulley transfers the kinetic energy to the large pulley through the belt, so that the rotating plate starts to rotate with the vertical rod as the axis, and the gas in the limited space underground is fully detected from multiple angles, the detection effect is good, and the detection result is more accurate.

[0016] Through the above technical solution, the air inside the manhole is turbid and contains many pollutants and bacteria. When the structure is used up, the disinfectant water in the disinfectant tank can be drawn through the atomizing nozzle to disinfect and sterilize the surface of the structure.
[0017] As a further solution of the utility model, a hose is connected between the atomizing nozzle and the disinfectant tank, a water pump is installed on the surface of the hose, and the water pump is electrically connected to the control module.
[0018] Through the above technical solution, the disinfectant in the disinfectant tank can be pumped into the atomizing nozzle by a water pump to clean and disinfect the structural components that have completed the detection.
[0019] Compared with the related art, the multi-angle air quality detector provided by the utility model has the following beneficial effects:
[0020] 1. In the present utility model, when gas detection is currently performed inside a space such as a well or an underground pipeline, a worker usually extends a hose and draws the internal air into the detector for detection through a pump body. This has defects. Since the length of the pipeline cannot be seen clearly from the outside, if there is sewage at the bottom of the pipeline, the pump body is likely to draw the sewage into the hose. At the same time, the position of the hose cannot be controlled. When the hose is extended into the pipeline, if the pipe mouth is attached to the pipe wall, impurities attached to it will be sucked in, causing the instrument to malfunction. The device installs the air quality detection module at the end of the rotating plate. The user can move the support seat above the manhole, and then extend the vertical rod into the manhole through the cooperation of the gear and the rack. At the same time, turn on the camera and the lighting lamp. The staff can view the situation inside the manhole through the display screen, which is convenient for adjusting the position of the air quality detection module at any time to detect the air composition in the underground limited space.
[0021] 2. In the utility model, the bottom of the manhole is connected to other underground spaces. In the traditional structure, detection is performed by inserting a hose. Since the angle cannot be adjusted for multi-directional detection, the detection accuracy is not high. In the device, when the air quality detection module reaches a suitable position, the telescopic cylinder is started to drive the rotating plate to adjust the angle, so that the end of the rotating plate moves to other underground spaces connected to the manhole, and then the small pulley is driven by the second motor. The small pulley transfers kinetic energy to the large pulley through the belt, so that the rotating plate starts to rotate with the vertical rod as the axis, and the gas in the limited space underground is fully detected from multiple angles, the detection effect is good, and the detection result is more accurate.

[0032] At present, when conducting gas detection inside spaces such as underground wells and underground pipelines, workers usually extend a hose and pump the internal air into the detector for detection through a pump body.

[0043] The working principle of a multi-angle air quality detector provided by the utility model is as follows:
[0044] Step 1: At present, when performing gas detection inside spaces such as underground wells and underground pipelines, workers usually extend a hose and pump the internal air into the detector for detection through a pump body. This has defects. Since the length of the pipeline cannot be seen from the outside, if there is sewage at the bottom of the pipeline, the pump body will easily pump the sewage into the hose. At the same time, the position of the hose cannot be controlled. When the hose is extended into the pipeline, if the pipe mouth is attached to the pipe wall, impurities attached to it will be sucked in, causing the instrument to malfunction.

[0045] The second step: the bottom of the manhole is connected to other underground spaces. In the traditional structure, detection is performed by inserting a hose. Since the angle cannot be adjusted for multi-directional detection, the detection accuracy is not high. In this device, when the air quality detection module 22 reaches a suitable position, the telescopic cylinder 10 is started to drive the rotating plate 9 to adjust the angle, so that the end of the rotating plate 9 moves to other underground spaces connected to the manhole, and then the small pulley 4 is driven by the second motor 11. The small pulley 4 transfers kinetic energy to the large pulley 12 through the belt 20, so that the rotating plate 9 starts to rotate with the vertical rod 5 as the axis, and the gas in the limited space underground is fully detected from multiple angles, the detection effect is good, and the detection result is more accurate.
