[0016] The present invention will be further described below in conjunction with the accompanying drawings: See attached Figure 1-9 In the present embodiment, an atmospheric environment monitoring device includes an anemometer 1, a top platform 2, a middle tube 3 and a base 5. A bearing sleeve 12 is fixedly connected at the middle position of the top platform 2, and a bearing 42 is installed inside the bearing sleeve 12. The anemometer 1 is rotatably connected to the bearing 42. The anemometer 1 is rotated by the wind, so that the magnitude of the wind force in the atmospheric environment can be measured. The lower end of the top platform 2 is fixedly connected to the middle tube 3. A waterproof ring 11 and a filter screen 25 are fixedly connected to the driving shaft of the anemometer 1, and the filter screen 25 is arranged below the waterproof ring 11. The arrangement of the waterproof ring 11 and the filter screen 25 can prevent dust, water and other impurities from entering the gap between the driving shaft of the anemometer 1 and the bearing sleeve 12, thereby causing the rotation of the anemometer 1 to be hindered, resulting in a large error in the wind speed measured by the anemometer 1.

[0017] The lower end of the top platform 2 is also fixedly connected with an oil cylinder 14 and an air cylinder 23. An oil pipe 40 is provided between the oil cylinder 14 and the bearing 42. One end of the oil pipe 40 is connected with the oil cylinder 14 and the other end extends to the top of the chamfer of the inner ring of the bearing 42. Because the inner ring rotates with the anemometer 1, when the bearing 42 is filled with oil for maintenance, the lubricating oil transported in the oil cylinder 14 can drip on the rotating inner ring, so that the lubricating oil can be more evenly distributed in the bearing 42, thereby improving the lubrication and maintenance effect of the bearing 42, making the anemometer 1 rotate more smoothly, and reducing the monitoring error. The oil cylinder 14 is provided with an oil guide mechanism, and the upper surface of the bearing sleeve 12 is provided with an air jet groove 43, the cross section of the air jet groove 43 is conical, and the conical air jet groove 43 can more effectively cover the entire filter screen 25 when jetting, so that the impurities on the filter screen 25 can be cleaned more cleanly, and a connected air storage groove 44 is provided below the air jet groove 43, and the air storage groove 44 is also annular. The annular air storage groove 44 is for allowing gas to be ejected from the entire annular air jet groove 43, so that the ejected gas can more effectively cover the entire filter screen 25 when jetting, and an air bag 32 is installed inside the air cylinder 23, and an air pipe 41 is provided between the air bag 32 and the air storage groove 44, and an air jet mechanism is provided on the air cylinder 23.

[0018] The oil guide mechanism includes a second fan blade 19, a second gear 22, a reciprocating screw 16 and a piston plate 13. A cover 10 is installed on the upper end of the oil cylinder 14. The reciprocating screw 16 is fixedly connected to the lower end of the cover 10 and the other end of the reciprocating screw 16 passes through the oil cylinder 14 and extends to the outside. The inner wall of the oil cylinder 14 is slidably connected to the piston plate 13. Lubricating oil is filled between the cover 10 and the piston plate 13. The oil cylinder 14 is arranged below the top platform 2 to avoid the oil cylinder 1 If it is set on the upper surface of the top platform 2, it will hinder the wind from blowing towards the anemometer 1, resulting in a large error in the monitoring result of the anemometer 1. The piston plate 13 is threadedly connected with the reciprocating screw 16, and the lower end of the piston plate 13 is fixedly connected with a guide rod 15 and a slide rod 24. The lower ends of the guide rod 15 and the slide rod 24 slide through the oil cylinder 14. The bottom of the oil cylinder 14 is provided with a slide groove 34. The slide rod 24 is slidably connected with the slide groove 34. The lower end of the reciprocating screw 16 is fixedly connected with a gear 17. The middle cylinder 3 is fixedly connected with a connecting plate 21, and the inner wall bottom of the middle cylinder 3 is rotatably connected with a second rotating shaft 20 via a one-way bearing. The one-way bearing ensures that the second rotating shaft 20 can only rotate in one direction, so as to avoid the second rotating shaft 20 rotating forward and reversely when the wind direction is different, resulting in the piston plate 13 being unable to rise stably, thereby failing to ensure the stability of the oil injection amount. The upper end of the second rotating shaft 20 passes through the connecting plate 21 and is fixedly connected with a second gear 22, which is meshed and connected with the first gear 17. The outer wall of the second rotating shaft 20 is fixedly connected with a second fan blade 19. A plurality of air guide boxes 4 are arranged on the inner wall of the middle cylinder 3. A filter screen 8 is inserted into the opening of the air guide box 4 away from the middle cylinder 3. A socket 9 is arranged on the upper end of the filter screen 8. When the anemometer 1 monitors the wind speed, the wind will also enter the middle cylinder 3 through the air guide box 4, thereby blowing the second fan blade 19 to rotate. When the second fan blade 19 rotates, it drives the second rotating shaft 20 to rotate. The second rotating shaft 20 synchronously drives the second gear 22 to rotate, the second gear 22 drives the first gear 17 to rotate, the first gear 17 drives the reciprocating screw 16 to rotate, and the rotation of the reciprocating screw 16 drives the piston plate 13 to move upward, thereby transporting the lubricating oil to the inside of the bearing 42 through the oil pipe 40, and the bearing 42 is oiled and maintained.

[0019] The lower end of the oil cylinder 14 is fixedly connected with an electric cylinder 18, a support block 35 and a pressure sensor 37. The output end of the electric cylinder 18 is installed with a stop block 26, which is made of rubber material. A driving tooth 2 46 is fixedly connected to the side wall of the slide bar 24. A push rod 36 is slidably connected to the support block 35. A driving tooth 1 45 is fixedly connected to one end of the push rod 36 close to the driving tooth 2 46. The driving tooth 1 45 is movably abutted against the driving tooth 2 46, and a spring 2 47 is sleeved on the outer wall of the push rod 36. The spring 2 47 is fixedly connected between the support block 35 and the driving tooth 1 45. When the piston plate 13 moves upward, The piston plate 13 will drive the slide bar 24 to move upward, and the driving tooth 2 46 on the slide bar 24 will also move upward. When each driving tooth 2 46 moves to the position of the driving tooth 1 45, the driving tooth 2 46 will squeeze the driving tooth 1 45, and the driving tooth 1 45 will push the push rod 36 to the right until one end of the push rod 36 squeezes the pressure sensor 37. The pressure sensor 37 will automatically control the output end of the electric cylinder 18 to extend through the control center, thereby driving the stop block 26 to abut against the surface of the gear 17, preventing the gear 17 from continuing to rotate, thereby realizing quantitative oiling maintenance of the inside of the bearing 42.

[0020] The jet mechanism includes an upper ring 33, a lower ring 31, a baffle 291 and an extrusion rod 28. The upper ring 33 is fixedly connected to the upper part of the air cylinder 23, and the lower end of the upper ring 33 is fixedly connected to the airbag 32. The lower end of the air pipe 41 passes through the upper ring 33 and is connected to the airbag 32. The other end of the air pipe 41 passes through the bearing sleeve 12 and is connected to the air storage tank 44. The width of the opening connecting the upper end of the air storage tank 44 with the jet groove 43 becomes smaller as it is closer to the air pipe 41. In this way, when the air pipe 41 is inflated into the air storage tank 44, the closer the inside of the air storage tank 44 is to the air pipe 41, the slower the speed at which the air is discharged from the air storage tank 44, so that the air can completely fill the air storage tank 44 and then be ejected from the air storage tank 44 into the jet groove 43 in a circular shape.

[0021] A guide block 38 is fixedly connected to the outer wall of the lower ring 31, a guide groove is provided on the air cylinder 23, the guide block 38 is slidably connected to the guide groove, and the upper end of the lower ring 31 is fixedly connected to the air bag 32, a one-way valve is installed on the air bag 32, a connecting rod 29 is fixedly connected to the lower end of the lower ring 31, and a baffle 291 is fixedly connected to the other end of the connecting rod 29, and the cross section of the baffle 291 is an arc shape. A limit block 39 is also fixedly connected to the inner wall of the bottom of the air cylinder 23, and a spring 30 is fixedly connected between the limit block 39 and the lower ring 31. A base 5 is fixedly connected to the lower part of the middle tube 3, a rotating shaft 6 is rotatably connected to the middle position of the base 5, a fan blade 7 is fixedly connected to the outer wall of the rotating shaft 6, a rotating shaft 20 is hollow inside, the rotating shaft 20 is sleeved on the outside of the rotating shaft 1 6 and the upper end of the rotating shaft 1 6 extends to the outside of the rotating shaft 20, a rotating head 27 is fixedly connected to the upper end of the rotating shaft 1 6, and a plurality of extrusion rods 28 are fixedly connected to the outer wall of the rotating head 27.

[0022] When the anemometer 1 monitors the wind speed, the wind will directly drive the fan blade 7 to rotate, the rotation of the fan blade 7 drives the rotation shaft 6, the rotation shaft 6 drives the rotating head 27 to rotate, and the rotating head 27 drives the squeezing rod 28 to rotate. When the squeezing rod 28 rotates, it will slide in contact with the baffle 291. At the same time, the squeezing rod 28 causes the baffle 291 to move downward. The baffle 291 drives the lower ring 31 to slide downward on the inner wall of the air cylinder 23 through the connecting rod 29 to squeeze the spring 30, and the lower ring 31 pulls the air bag 32 to expand and inflate. When the squeezing rod 28 rotates and staggers with the baffle 291, the squeezing rod 28 releases the squeezing of the baffle 291, and the spring 30 resets to drive the lower ring 31 to quickly squeeze the air bag 32. The air bag 32 sprays air from the air pipe 41 to the air storage tank 44, and subsequently blows off the impurities attached to the filter screen 25 to ensure the filtering effect of the filter screen 25.

[0023] How it works When the atmospheric environment monitoring device monitors the wind speed, the wind drives the anemometer 1 to rotate, and the wind also enters the middle tube 3 through the wind guide box 4, thereby driving the fan blade 2 19 to rotate, and then the reciprocating screw 16 is driven to rotate through the gear 2 22 and the gear 1 17. The rotation of the reciprocating screw 16 drives the piston plate 13 to move upward, so that the lubricating oil is transported to the inside of the bearing 42 through the oil pipe 40, and the bearing 42 is oiled and maintained to ensure the smooth and stable rotation of the anemometer 1 and the accuracy of the monitoring results. At the same time, the wind also drives the fan blade 7 to rotate, and then the extrusion rod 28 is rotated to slide in contact with the baffle 291, and the extrusion rod 28 causes the baffle 291 to move downward. , the baffle 291 drives the lower ring 31 to pull the airbag 32 to expand and inflate through the connecting rod 29. When the extrusion rod 28 rotates and staggers with the baffle 291, the extrusion rod 28 releases the extrusion of the baffle 291, and the spring 1 30 resets to drive the lower ring 31 to quickly squeeze the airbag 32. The airbag 32 sprays air from the air pipe 41 to the air storage tank 44, and then blows out the impurities attached to the filter screen 25 from the inside to the outside, so that the impurities are separated from the filter screen 25, ensuring the filtering effect of the filter screen 25, and preventing impurities from entering the gap between the drive shaft and the bearing sleeve 12 and entering dust, water and other impurities, thereby hindering the rotation of the anemometer 1, resulting in a large error in the wind speed measured by the anemometer 1.
