DETAILED DESCRIPTION

[0025] See also Figure 1-4 ,

[0026] Embodiment 1: A production safety monitoring device includes a monitor 1, a power line 2 is provided on the side of the monitor 1, an alarm 3 is installed on the other side of the monitor 1, a dust sensor 4 is connected to the bottom end of the monitor 1, and a sensor cleaning component 5 for cleaning dust is provided on the dust sensor 4.

[0027] The sensor cleaning assembly 5 includes a protective sleeve 501 that is sleeved on the outside of the dust sensor 4. Several side openings 502 are evenly opened on the protective sleeve 501. Two fixing screw grooves 503 are symmetrically opened at the bottom ends of both sides of the protective sleeve 501. The bottom end of the protective sleeve 501 is sleeved with a connecting base 504. A bottom jack 506 is opened in the middle of the bottom end of the connecting base 504. Two dust discharge ports 505 are symmetrically opened on both sides of the bottom jack 506. A servo motor 507 is provided at the bottom end of the connecting base 504, and the output shaft of the servo motor 507 is connected to a transmission rod 508.

[0028] The top end of the transmission rod 508 rotates and passes through the bottom socket 506. A driving disc 509 is arranged above the bottom socket 506. The top end of the transmission rod 508 is fixedly connected to the middle part of the bottom end of the driving disc 509. Two fixed sockets 510 are symmetrically provided on both sides of the connecting base 504. Fixed screws 511 are inserted in the fixed sockets 510. The ends of the fixed screws 511 pass through the fixed sockets 510 and extend into the fixed screw grooves 503. Two dust cleaning connecting plates 512 are symmetrically provided at the top end of the driving disc 509. The sides of the dust cleaning connecting plates 512 are provided with side slots 513.

[0029] A cleaning scraper 514 is provided in the side groove 513, and three mounting holes 515 are evenly provided on the inner wall of the side groove 513. A connecting rod 516 is inserted into the mounting hole 515, and the end of the connecting rod 516 is connected to the side of the cleaning scraper 514. A resistance spring 517 is sleeved on the connecting rod 516, and one end of the resistance spring 517 is connected to the rod body of the connecting rod 516, and the other end of the resistance spring 517 is connected to the side of the cleaning connecting plate 512.

[0030] Embodiment 2: The difference between this embodiment and embodiment 1 is that the servo motor 507 is connected to the bottom end of the connecting base 504 through a fixed frame.

[0031] This makes it more stable when the servo motor 507 drives the driving disc 509 through the transmission rod 508.

[0032] Embodiment 3: The difference between this embodiment and embodiment 1 is that a connecting plate is provided at the end of the connecting rod 516 .

[0033] This makes it more stable for the resisting spring 517 to be sleeved on the connecting rod 516 .

[0034] Embodiment 4: The difference between this embodiment and embodiment 1 is that the inner side wall of the cleaning scraper 514 is in an arc shape to facilitate fitting against the outer side of the dust sensor 4 , and the side surface of the cleaning scraper 514 fits against the outer side of the dust sensor 4 .

[0035] This enables the cleaning scraper 514 to better scrape off the dust adhering to the surface of the dust sensor 4.

[0036] In this embodiment, since the existing dust monitor used in cement production plants is actually used, there is a lot of dust mixed in the air, and the flying dust can easily accumulate on the sensor on the dust monitor, thereby affecting the monitoring sensitivity of the sensor and making it difficult to ensure its long-term safe operation.

[0037] In summary, in specific implementation, when the monitor 1 installed in the cement plant has been used for a long time, a certain amount of dust will definitely adhere to the surface of the dust sensor 4 installed at the bottom of the monitor 1, thereby affecting the dust concentration monitoring accuracy of the dust sensor 4. By arranging a sensor cleaning component 5 on the outside of the dust sensor 4, wherein the protective sleeve 501 in the sensor cleaning component 5 is sleeved on the outside of the dust sensor 4, it can play a certain protective role for the dust sensor 4, and the side openings 502 evenly opened on the protective sleeve 501 can allow the dust in the air to normally enter the outside of the dust sensor 4, thereby facilitating the monitoring use of the dust sensor 4.

[0038] When a lot of dust adheres to the surface of the dust sensor 4, the user can start the servo motor 507, which drives the driving disc 509 to rotate through the transmission rod 508. Two cleaning connecting plates 512 are symmetrically provided on the driving disc 509. The sides of the cleaning connecting plates 512 are provided with cleaning scrapers 514. The cleaning scrapers 514 are connected by connecting rods 516. The connecting rods 516 are provided with resistance springs 517. Under the action of the rebound force of the resistance springs 517, the cleaning scrapers 514 can be more closely fitted to the surface of the dust sensor 4. Thereby, the cleaning scraper 514 arranged on the outside of the dust sensor 4 can better scrape the dust adhered to the surface of the dust sensor 4, and the scraped dust can be discharged through the dust discharge port 505, thereby avoiding the accumulation of dust in the protective sleeve 501 and affecting the dust sensor 4. A fixing screw groove 503 is provided on the side of the protective sleeve 501, and a fixing socket 510 is provided on the side of the connecting base 504, which makes it more convenient for users to disassemble and assemble the protective sleeve 501, ensuring that the dust sensor 4 can maintain a relatively sensitive monitoring function for a long time.
