[0001] The present invention relates to the technical field of air detection, and in particular to a mobile urban road air detection device which is easy to adjust. Background Art

[0002] As people pay more and more attention to their living environment, they often conduct corresponding air detection in life scenes, especially in some construction areas, which often cause relatively serious air pollution. The detection device uses its own sensor mechanism to perform corresponding air quality detection.

[0003] The patent with publication number CN202321477844.6 in the prior art is provided with an air detection mechanism, and the moving block on the air detection mechanism is installed on the rotating shaft A, and the driven gear on the rotating shaft A is matched with the driving gear on the rotating shaft B, so that the motor drives the rotating shaft B to rotate, and the rotating shaft A also rotates synchronously, thereby achieving the height adjustment of the moving block, and trying to avoid the situation where the air pollution detection value is affected by errors or inaccuracies due to a high air detection. By utilizing the air quality detector and display screen on the moving block and connecting the data between them by a cable line, the air quality detector performs air detection and the display screen performs air data display and processing, which is convenient for users to observe the air detection values, effectively improving the use effect and experience of the mobile urban road air detection device, and at the same time effectively enhancing the accuracy of the mobile urban road air detection device, so as to solve the problem that the mobile urban road air detection device cannot be effectively adjusted and affects its accuracy proposed in the above background technology.

[0004] The above patent provides an air detection device that can easily adjust the detection height. However, since the air detection device contacts the air through the exposed detection sensor part, and then performs corresponding detection work on the air quality, the sensor part is in contact with the air for a long time, which will cause the sensor surface to be covered with excess dust and other impurities, seriously affecting the detection sensitivity of the sensor, and causing large errors in the detection data results at different detection heights, seriously affecting the analysis results of the air quality.

Sensor heads 5 are symmetrically arranged on both sides of the interior of the detection box 4, and two connecting frames 6 are symmetrically slidably connected on both sides of the interior of the detection box 4. A cleaning sleeve 7 is fixedly connected to one side of the connecting frame 6, and the cleaning sleeve 7 is slidably connected to the sensor head 5. A cleaning mechanism 8 is arranged inside the cleaning sleeve 7, and the cleaning mechanism 8 includes two jet drying rings 801, a brush ring 802 and a wiping ring 803. The two jet drying rings 801 are symmetrically embedded in the cleaning sleeve 7 , the brush ring 802 and the wiping ring 803 are both embedded in the cleaning sleeve 7, and the brush ring 802 and the wiping ring 803 are both located between the two jet drying rings 801. The wiping ring 803 can use alcohol to wet and wipe the sensor head 5 after being brushed by the brush ring 802. One side of the surface of the connecting frame 6 is symmetrically provided with two grooves 16, and the interiors of the two grooves 16 are hinged with pressure plates 17. The interiors of the grooves 16 are fixedly connected with two air bags 18, and the two ends of the pressure plate 17 alternately squeeze the two air bags 18. The two air bags 18 are respectively connected to the two jet drying rings 801. Buffer columns 24 are provided at the four corners of the bottom of the mobile base 1. The bottom of the buffer column 24 is rotatably connected to a universal wheel 25, and one side of the top of the mobile base 1 is fixedly connected to a moving handle 26.

[0020] Among them, the detection box 4 is driven to slide upward along the guide rod 3 by the telescopic cylinder 2, and at the same time, the two connecting frames 6 are forced to slide from the two sides inside the detection box 4 in the direction of approaching each other. In the process of the cleaning sleeve 7 sliding along the sensor head 5, the brush ring 802 will clean the dust and other impurities accumulated on the surface of the sensor head 5, and then the sensor head 5 is wet wiped and cleaned by the wiping ring 803 to further ensure the cleaning effect of the dust on the surface of the sensor head 5, and in the process of the sliding of the connecting frame 6, one end of the pressure plate 17 will squeeze the air bag 18 on one side, forcing one of the jet drying rings 801 to quickly jet dry the wiped sensor head 5, ensuring the cleaning effect while drying the sensor head 5 to ensure the normal operation of the sensor head 5.

[0021] The surfaces of the opposite sides of the two guide rods 3 are fixedly connected with teeth 9, and the two sides of the surface of the detection box 4 are symmetrically rotatably connected with two wheels 10, one side of the wheel 10 is engaged with the teeth 9, and the inside of the wheel 10 is unidirectionally meshed with a rotating tooth 11 through a ratchet, and the side of the rotating tooth 11 away from the wheel 10 is fixedly connected with a screw 12, and the screw 12 is connected to the internal thread of the connecting frame 6. An annular groove 13 is provided inside the wheel 10, and a coil spring 14 is fixedly connected to the inside of the annular groove 13, and the other end of the coil spring 14 is fixedly connected to a slider 15, which is slidably connected to the inside of the annular groove 13, and one end of the slider 15 passes through the outside of the annular groove 13 and is fixedly connected to the rotating tooth 11.

[0022] Among them, in the process of the detection box 4 sliding upward along the guide rod 3, the teeth 9 engage and rotate with the sleeve wheel 10. At this time, the rotation of the sleeve wheel 10 will drive the rotating teeth 11 to rotate through the ratchet, thereby driving the screw 12 to rotate. The effect of the threaded connection can force the two connecting frames 6 to slide in the direction of approaching each other, and at this time, the rotating teeth 11 will squeeze the coil spring 14 inside the annular groove 13 through the slider 15. When the detection box 4 stops sliding upward, the rotating teeth 11 are driven to rotate in the opposite direction by the restoring effect of the coil spring 14. At this time, the sleeve wheel 10 cannot be unidirectionally engaged with the rotating teeth 11, and can drive the connecting frame 6 to automatically reset, making it convenient to work again.

[0023] Two rings 19 are symmetrically fixedly connected to both sides of the detection box 4, and a connecting block 20 is fixedly connected to one side of the inner wall of the ring 19. The other end of the connecting block 20 is fixedly connected to the telescopic end of the telescopic cylinder 2. The surfaces of the two guide rods 3 on the opposite sides are provided with slots 21. The connecting block 20 is slidably connected to the guide rod 3 through the slots 21. A display screen 22 is embedded in one side of the surface of the detection box 4. A through hole 23 is opened through the side of the two rings 19 close to the detection box 4, and the teeth 9 are slidably connected to the ring 19 through the through hole 23.

[0024] Among them, through the connection effect between the telescopic end of the telescopic cylinder 2 and the connecting block 20, the two rings 19 can be smoothly driven to slide up and down along the guide rod 3, and the notch 21 can ensure that the sliding of the connecting block 20 will not be restricted, and when the ring 19 contacts the teeth 9, the through hole 23 can ensure that the sliding effect of the ring 19 will not be hindered by the teeth 9, thereby ensuring the smooth operation of the device.

[0025] The specific working principle and method of use of the present invention are explained in detail below: When in use, the first step is to drive the detection box 4 to slide upward along the guide rod 3 through the telescopic cylinder 2. At the same time, the two connecting frames 6 are forced to slide from the two sides of the inside of the detection box 4 in the direction of approaching each other. In the process of the cleaning sleeve 7 sliding along the sensor head 5, the brush ring 802 will clean the dust and other impurities accumulated on the surface of the sensor head 5, and then the sensor head 5 will be wet-wiped and cleaned by the wiping ring 803 to further ensure the cleaning effect of the dust on the surface of the sensor head 5. In the process of the sliding of the connecting frame 6, one end of the pressure plate 17 will squeeze the air bag 18 on one side, forcing one of the jet drying rings 801 to quickly jet dry the wiped sensor head 5, ensuring the cleaning effect while drying the sensor head 5; In the second step, when the detection box 4 slides upward along the guide rod 3, the teeth 9 engage and rotate with the sleeve 10. At this time, the rotation of the sleeve 10 will drive the rotating teeth 11 to rotate through the ratchet, thereby driving the screw 12 to rotate. The effect of the threaded connection can force the two connecting frames 6 to slide in the direction of approaching each other, and at this time, the rotating teeth 11 will squeeze the coil spring 14 inside the annular groove 13 through the slider 15. When the detection box 4 stops sliding upward, the rotating teeth 11 are driven to rotate in the opposite direction by the restoring effect of the coil spring 14. At this time, the sleeve 10 cannot be unidirectionally engaged with the rotating teeth 11, and can drive the connecting frame 6 to automatically reset.

[0026] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
