[0002] The air and pulverized coal monitoring device can adjust the supply amount of pulverized coal by monitoring the wind speed in real time, ensuring the stability and efficiency of combustion. This is crucial for optimizing the combustion process of pulverized coal. In addition, accurately controlling the wind speed is of great significance for extending the service life of pipelines and reducing maintenance costs.

[0003] According to a disclosed full-section air and pulverized coal online monitoring device (publication number: CN206974996U), the rubber pad in the above application can play a good buffering role, thus well protecting the monitoring device body from damage.

[0024] As Figures 1-5 shown, the present utility model provides a technical solution: a monitoring device, including a protective housing 1, a heat dissipation pipe 2 is fixedly installed on the right side of the protective housing 1, which can dissipate heat from the inside of the protective housing 1, an air inlet pipe 3 is fixedly installed at the bottom of the protective housing 1, a monitoring device body 4 is arranged inside the protective housing 1, and a clamping mechanism 5 is arranged inside the protective housing 1, which can fixedly install monitoring device bodies 4 of different sizes.

[0025] Specifically, the clamping mechanism 5 includes: an up-and-down telescopic rod 51, a placement seat 52, a connecting rod 53, a left-and-right telescopic rod 54, a clamping spring 55, a clamping plate 56, a rotating shaft 57, a turntable 58, a compression spring 59, a rotating rod 510, a threaded rod 511, an idle groove 512, a nut 513, a fixed rod 514, a moving groove 515, a return spring 516, a moving block 517, an inclined block 518, an up-and-down rod 519, a pressing rod 520, a connecting rod 521, a sliding rod 522, and a cylinder 523. The bottom of the up-and-down telescopic rod 51 is fixedly installed at the inner bottom of the protective housing 1 to facilitate the installation of the placement seat 52. One end of the up-and-down telescopic rod 51 away from the protective housing 1 is fixedly installed with the placement seat 52 to facilitate the placement of the monitoring device body 4. A connecting rod 53 is hinged to the side of the placement seat 52, which can drive the left-and-right telescopic rod 54 to move towards the middle when the placement seat 52 moves downward. One end of the connecting rod 53 away from the placement seat 52 is hinged to the left-and-right telescopic rod 54 to facilitate the installation of the clamping spring 55. The left side of the left-and-right telescopic rod 54 is fixedly installed on the left side inside the protective housing 1. The clamping spring 55 can facilitate the installation of the clamping plate 56. The left side of the clamping spring 55 is fixedly installed on the right side of the left-and-right telescopic rod 54. One end of the clamping spring 55 away from the left-and-right telescopic rod 54 is fixedly installed with the clamping plate 56, which can clamp the monitoring device body 4. The left-and-right telescopic rod 54, the clamping spring 55, and the clamping plate 56 are provided in two groups and are symmetrically distributed about the central axis of the side surface of the protective housing 1 on the left and right sides of the protective housing 1.It can clamp the left and right sides of the monitoring device body 4, enabling better fixation of the monitoring device body 4. The back of the clamping plate 56 is slidably installed on the inner wall of the protective housing 1 for guiding. A threaded rod 511 is rotatably installed at the through hole at the bottom of the protective housing 1 to facilitate the installation of the nut 513. There is a rotating shaft 57, and the outer wall of the rotating shaft 57 is rotatably installed at the through hole at the bottom of the threaded rod 511, which can drive the rotating rod 510 to rotate. A turntable 58 is fixedly installed on the outer wall of the rotating shaft 57 and can be manually rotated to make the rotating shaft 57 rotate. A compression spring 59 is fixedly installed in the top groove of the rotating shaft 57, which can reset the rotating rod 510 after being squeezed. One end of the compression spring 59 away from the rotating shaft 57 is fixedly installed with the rotating rod 510, which can drive the threaded rod 511 to rotate when not being squeezed. The outer wall of the rotating rod 510 is slidably installed in the groove of the rotating shaft 57. An idle running groove 512 is opened inside the threaded rod 511, so that when the rotating rod 510 is squeezed, the convex block on it rotates in the idle running groove 512, and in this way, the rotating rod 510 cannot drive the threaded rod 511 to rotate. The outer wall of the threaded rod 511 is threadedly connected with the nut 513, which can drive the fixed rod 514 to move. The outer wall of the nut 513 is fixedly installed with the fixed rod 514, which can drive the placement seat 52 to move up and down. One end of the fixed rod 514 away from the nut 513 is fixedly installed on the left side of the placement seat 52. A moving groove 515 is opened on the front of the left and right telescopic rods 54 to facilitate the installation of the return spring 516 and the moving block 517. The return spring 516 is fixedly installed on the right side of the moving groove 515. One end of the return spring 516 away from the moving groove 515 is fixedly installed with the moving block 517. The outer wall of the moving block 517 is slidably installed inside the moving groove 515 for guiding. The bottom of the moving block 517 is fixedly installed with an inclined plane block 518, which can squeeze the upper and lower rod 519 to move downward when the moving block 517 is squeezed by the clamping plate 56. The upper and lower rod 519 is slidably installed inside the moving groove 515 for guiding. An extrusion rod 520 is fixedly installed on the front of the upper and lower rod 519, which can squeeze the connecting rod 521 and the sliding rod 522. The bottom of the extrusion rod 520 is in contact with the connecting rod 521 to facilitate the installation of the cylinder 523. The right side of the connecting rod 521 is slidably installed on the right side of the protective housing 1, which can facilitate downward sliding during extrusion. The sliding rod 522 is slidably installed in the groove of the connecting rod 521, so that when the left and right telescopic rods 54 move, the extrusion rod 520 can squeeze the connecting rod 521. The left side of the sliding rod 522 is slidably installed on the right side of the clamping plate 56. The bottom of the connecting rod 521 is fixedly installed with a cylinder 523, which can squeeze the rotating rod 510 to move downward. The bottom of the cylinder 523 is in contact with the bottom of the rotating rod 510.

[0026] Working principle: When the main body 4 of the monitoring device is placed on the placement seat 52 inside the protective housing 1, by rotating the turntable 58, the rotating shaft 57 rotates and drives the rotating rod 510 to rotate at the same time. When the rotating rod 510 rotates, it drives the threaded rod 511 to rotate. In this way, the nut 513 can move up and down on the threaded rod 511. The up and down movement of the nut 513 can drive the fixed rod 514 to move up and down, so that the placement seat 52 also moves up and down, and the up and down telescopic rod 51 expands and contracts, so that the connecting rod 53 drives the left and right telescopic rods 54 to move. When the left and right telescopic rods 54 drive the clamping spring 55 to move, the clamping plate 56 moves, and the clamping plate 56 slides inside the protective housing 1, which can fix the main body 4 of the monitoring device. In this way, the main body 4 of the monitoring device with different sizes can be fixedly installed, increasing the versatility of the protective housing 1.

[0027] If, when rotating the turntable 58, the rotation is excessive and the main body 4 of the monitoring device is pinched, after the clamping plate 56 is clamped, the clamping spring 55 can be squeezed, and then the moving block 517 is squeezed, so that the moving block 517 slides in the moving groove 515, and the return spring 516 is compressed. When the moving block 517 moves, it can drive the inclined plane block 518 to squeeze the inclined plane of the up and down rod 519, so that it moves downward, driving the extrusion rod 520 to move downward. At the same time, the connecting rod 521 is squeezed. When the clamping plate 56 is clamped, the sliding rod 522 will be pulled out of the connecting rod 521, so that the extrusion rod 520 moves on the surfaces of the sliding rod 522 and the connecting rod 521. When the extrusion rod 520 moves downward, the connecting rod 521 and the sliding rod 522 move downward, and slide at the connection between the protective housing 1 and the clamping plate 56. The downward movement of the connecting rod 521 drives the cylinder 523 to move downward, which can make the cylinder 523 squeeze the rotating rod 510, so that the rotating rod 510 slides into the inside of the rotating shaft 57, and the extrusion spring 59 is compressed. At the same time, the protruding part at the top of the rotating rod 510 presses against the idle rotation groove 512. In this way, when rotating the turntable 58, the threaded rod 511 cannot be driven to rotate, and the main body 4 of the monitoring device can be prevented from being pinched.

However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements that do not depart from the spirit of the present invention are all within the protection scope of the present invention.
