However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-Figure 7 A coal mine dust monitoring device shown includes a monitor 1 and a detection probe 101, a sound and light alarm 2 is arranged on the surface of the monitor 1, the detection probe 101 is arranged at the bottom of the monitor 1, a mounting assembly 4 is arranged on one side of the monitor 1, and an auxiliary structure 3 is arranged at the bottom of the monitor 1; The auxiliary structure 3 includes a dustproof component 31 disposed at the bottom of the monitor 1, and a detachable collection component 32 is disposed at the bottom of the dustproof component 31; Among them, the dustproof component 31 includes a shell 3101 arranged at the bottom of the monitor 1, and the surface of the shell 3101 is provided with evenly distributed through grooves 3103. The inner bottom wall of the shell 3101 is fixedly connected with a mounting block 3102. A detection cavity is formed between the top of the mounting block 3102 and the interior of the shell 3101, and the detection probe 101 extends into the interior of the detection cavity.

[0021] External dust can enter the detection chamber through the through slot 3103 along with the air flow for detection by the detection probe 101. The monitor 1, the detection probe 101 and the sound and light alarm 2 are all relatively mature components in the existing technology application and will not be described in detail here.

[0022] like Figure 1-Figure 7As shown, an installation cavity 3105 is provided inside the installation block 3102, a motor 3109 is arranged inside the installation cavity 3105, an output shaft of the motor 3109 is fixedly connected to a connecting shaft 3107, a fan blade 3108 is fixedly connected to the surface of the connecting shaft 3107, ventilation holes 3104 which are evenly distributed and connected to the installation cavity 3105 are provided on the top of the installation block 3102, and an installation hole is provided on the bottom of the installation block 3102.

[0023] The upper end of the connecting shaft 3107 passes through the mounting block 3102 and is fixedly connected to a connecting plate 3110. The top of the connecting plate 3110 is fixedly connected to a first cleaning rod 3111, and the surface of the first cleaning rod 3111 is in contact with the surface of the detection probe 101. The top of the connecting plate 3110 is also fixedly connected to a second cleaning rod 3112, and the surface of the second cleaning rod 3112 is in contact with the inner wall of the outer shell 3101.

[0024] A cavity 3113 is defined inside the second cleaning rod 3112, a notch 3115 communicating with the cavity 3113 is defined on the surface of the second cleaning rod 3112, a guide groove 3114 communicating with the cavity 3113 is defined at the bottom of the connecting plate 3110, and the cavity 3113 is communicated with the ventilation hole 3104 via the guide groove 3114.

[0025] By starting the motor 3109, the connecting shaft 3107 connected thereto can be driven to rotate, thereby driving the fan blades 3108 to rotate and guide the external airflow to pass through the through slot 3103 into the interior of the detection chamber, and guide the airflow to pass through the ventilation hole 3104 and the installation cavity 3105 and be discharged through the installation hole, thereby reducing the dust staying inside the detection chamber. During the rotation of the connecting shaft 3107, the connecting plate 3110 can be driven to rotate synchronously, and the first cleaning rod 3111 is used to clean the surface of the detection probe 101 to reduce the situation where dust sticks to the surface of the detection probe 101 and affects the subsequent monitoring effect. At the same time, the second cleaning rod 3112 can be driven to clean the inner wall of the outer shell 3101 to reduce the dust sticking to the interior of the outer shell 3101. When the subsequent airflow enters, some dust is blown up to affect the monitoring effect. As a result, during the movement of the second cleaning rod 3112, the notch 3115 allows the adhered dust to enter the interior of the cavity 3113, and as the second cleaning rod 3112 rotates, the position where the second cleaning rod 3112 contacts the outer shell 3101 is used to scrape and clean the dust, and the scraped dust can be trapped in the cavity 3113, thereby reducing the situation where the airflow drives this part of the dust to be detected by the detection probe 101. Due to the setting of the guide groove 3114, part of the airflow enters the interior of the cavity 3113 through the notch 3115, and drives the dust inside the cavity 3113 to enter the interior of the guide groove 3114, and finally is introduced into the interior of the installation cavity 3105 through the ventilation hole 3104, so that the cleaned dust will not flow back to the interior of the detection cavity, thereby improving the monitoring effect.

[0026] like Figure 1-Figure 7 As shown, a skirt 3106 is fixedly connected to the bottom of the housing 3101 , and an internal thread is provided on the inner side of the skirt 3106 . The skirt 3106 is used for installing the collecting assembly 32 .

[0027] The collecting assembly 32 includes a mounting shell 3201 arranged on the inner side of the skirt 3106 , the surface of the mounting shell 3201 is fixedly connected to the edge 3202 , the surface of the edge 3202 is provided with external threads, and the surface of the mounting shell 3201 is provided with exhaust holes 3206 evenly distributed and located below the edge 3202 .

[0028] A connecting pipe 3204 is provided inside the mounting shell 3201, the upper end of the connecting pipe 3204 is connected to the mounting hole, the surface of the connecting pipe 3204 is provided with evenly distributed through holes 3203, the surface of the connecting pipe 3204 is fixedly connected with evenly distributed mounting plates 3205, the other end of the mounting plate 3205 is fixedly connected to the inner wall of the mounting shell 3201, and the interior of the mounting shell 3201 is filled with dust reduction water.

[0029] The external thread on the surface of the edge 3202 and the internal thread on the inner side of the skirt 3106 can realize the quick installation and disassembly of the mounting shell 3201, and the dust introduced into the interior of the mounting cavity 3105 can be introduced into the interior of the connecting pipe 3204 and discharged through the through hole 3203. The specific liquid level of the dust reduction water is higher than the opening height of the through hole 3203, so that the airflow and dust discharged through the through hole 3203 can enter the interior of the dust reduction water, realize the dust reduction collection and treatment of the dust, and reduce the dust content in the subsequent airflow discharged through the exhaust hole 3206.

[0030] like Figure 1-Figure 5 As shown, the mounting assembly 4 includes two connecting blocks 407 fixedly connected to the surface of the monitor 1, a connecting rod 401 is arranged between the two connecting blocks 407, two clamping strips 402 are fixedly connected to the surface of the connecting rod 401, both ends of the connecting rod 401 are fixedly connected to a rotating shaft 408, the other end of the rotating shaft 408 is rotatably connected to the inner wall of the connecting block 407, a spring 406 is fixedly connected to the surface of the rotating shaft 408, and the other end of the spring 406 is fixedly connected to the inner wall of the connecting block 407.

[0031] The mounting assembly 4 also includes a gasket 405 fixedly connected to the surface of the monitor 1 . The surface of the clamp 402 contacts the surface of the gasket 405 . The surface of the clamp 402 is provided with a threaded hole 403 . The internal thread of the threaded hole 403 is connected with a mounting bolt 404 .

[0032] By pulling the clamp 402, the connecting rod 401 and the rotating shaft 408 can be used to rotate around the rotating shaft 408. In this process, the spring 406 can be tightened and the clamp 402 can be reset under the action of the spring 406 after it is loosened. The clamp 402 can be used to clamp the device on the workers' clothes without the need for the workers to hold it. Especially during the coal mining work, the workers can clamp the device on their clothes without affecting their normal work. At the same time, they can monitor the surrounding dust concentration at all times, avoiding the situation where it is inconvenient to change the monitoring position after the traditional monitoring equipment is installed. At the same time, the dustproof component 31 can reduce the dust content around the workers during monitoring and optimize the working environment.

[0033] The setting of the gasket 405 can strengthen the clamping effect between the clamp strip 402, increase the friction with the clothes, and reduce the possibility of falling off. The set threaded holes 403 and mounting bolts 404 can clamp the device on the mounting part through the clamp strip 402 and the gasket 405 when it is needed to fix the device on the mounting part, and further limit the position of the device by installing the mounting bolts 404.

[0034] Working principle: By starting the motor 3109, the connecting shaft 3107 connected thereto can be driven to rotate, thereby driving the fan blades 3108 to rotate and guide the external airflow to pass through the through slot 3103 into the interior of the detection chamber, and guide the airflow to pass through the ventilation hole 3104 and the installation cavity 3105 and be discharged through the installation hole, thereby reducing the dust staying inside the detection chamber. During the rotation of the connecting shaft 3107, the connecting plate 3110 can be driven to rotate synchronously, and the first cleaning rod 3111 is used to clean the surface of the detection probe 101 to reduce the situation where dust sticks to the surface of the detection probe 101 and affects the subsequent monitoring effect. The second cleaning rod 3112 is used to clean the inner wall of the outer shell 3101 to reduce the situation where dust sticks to the interior of the outer shell 3101 and some dust is blown up when the subsequent airflow enters and affects the monitoring result, thereby improving the monitoring effect. The setting of the installation component 4 can make the use scenario of the device more flexible.
