Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof gas spectral imagers, in particular to an explosion-proof gas spectral imager with a rotating mechanism. Background Technique

[0002] A gas spectral imager is an advanced instrument for gas analysis and detection. The gas spectral imager uses hyperspectral imaging technology to scan the gas in the atmosphere. According to the spectral reflection and absorption conditions of different wavelengths, qualitative and quantitative analysis of the gas is carried out. It identifies and quantifies the presence of gas based on the absorption or reflection characteristics of specific wavelengths of light by different gases.

[0003] When an explosion-proof gas spectral imager is in use, it usually needs to scan the atmosphere from multiple angles. Therefore, a rotating mechanism needs to be set to drive the explosion-proof gas spectral imager to rotate to meet the scanning work of the atmosphere. However, when the existing rotating mechanism is in use, it only has a single horizontal rotation adjustment function, which will result in only being able to perform horizontal rotation scanning of the atmosphere at a fixed angle. It is difficult to achieve when it is necessary to scan the atmosphere in the space obliquely above or above the explosion-proof gas spectral imager, and the functionality is insufficient. Therefore, we propose an explosion-proof gas spectral imager with a rotating mechanism. Summary of the Utility Model

When the existing rotating mechanism is in use, it only has a single horizontal rotation adjustment function, which will result in only being able to perform horizontal rotation scanning of the atmosphere at a fixed angle.

The lifting structure can drive the angle adjustment mechanism to perform up and down adjustment to drive the explosion-proof gas spectral imager body to perform pitching angle adjustment.

[0007] Preferably, the rotating structure includes a driving motor. The top of the driving motor is connected with an output shaft. The driving motor can drive the output shaft to rotate.

[0026] Embodiment 1

[0027] As Figures 1-5 shown, the present utility model provides a technical solution: an explosion-proof gas spectral imager with a rotating mechanism, which includes a fixed base 1. A rotating structure 2 is provided inside the fixed base 1. An auxiliary limiting structure 3 is sleeved on the connection part of the rotating structure 2. An angle adjusting mechanism 5 is provided at the connection part of the auxiliary limiting structure 3. A lifting structure 4 is connected to the outside of the angle adjusting mechanism 5. The top of the angle adjusting mechanism 5 is fixedly connected to an explosion-proof gas spectral imager body 6. The lifting structure 4 can drive the angle adjusting mechanism 5 to perform up and down adjustment, so as to drive the explosion-proof gas spectral imager body 6 to perform pitching angle adjustment. The rotating structure 2 can drive the explosion-proof gas spectral imager body 6 to perform 360° non-dead-angle rotation to meet the multi-angle detection requirements of the explosion-proof gas spectral imager body 6. Moreover, the lifting structure 4 can drive the angle adjusting mechanism 5 to move up and down on the auxiliary limiting mechanism, so that the angle adjusting mechanism 5 can perform up and down pitching angle adjustment. When used in cooperation with the rotating structure 2, it can form a rotation adjustment while performing pitching angle adjustment, thereby realizing non-dead-angle adjustment.

[0028] Embodiment 2

[0029] As Figures 1-5 shown, the present utility model provides a technical solution: The rotating structure 2 includes a driving motor 21. The top of the driving motor 21 is connected with an output shaft 22. The driving motor 21 can drive the output shaft 22 to rotate.

[0030] The auxiliary limiting structure 3 includes a fixed seat 31. Sliding grooves 32 are respectively opened on the peripheral walls of the fixed seat 31. Sliding blocks 33 are respectively slidably connected inside the four sliding grooves 32. The fixed seat 31 is fixedly connected with the fixed base 1. The inside of the fixed seat 31 does not contact the output shaft 22. The sliding block 33 can slide in the sliding groove 32. Since the inside of the fixed seat 31 does not contact the output shaft 22, the fixed seat 31 will not be driven to rotate when the output shaft 22 rotates.

[0031] The lifting structure 4 includes two pneumatic rods 41. Fixed shells 42 are provided at the connection parts of the two pneumatic rods 41. Connecting pieces 43 are provided at the output ends of the two pneumatic rods 41. A fixed ring 44 is provided between the two connecting pieces 43. The extension of the pneumatic rod 41 will drive the connecting piece 43 and the fixed ring 44 to move. The fixed ring 44 is fixedly installed on the adjusting seat 51, so as to drive the adjusting seat 51 to slide on the sliding block 33, thereby realizing the up and down movement of the adjusting seat 51.

[0032] The angle adjustment mechanism 5 includes an adjusting seat 51. A sliding ring 52 is provided above the adjusting seat 51. A sliding cavity 53 is formed on the inner side wall of the sliding ring 52. Limit rings 54 are provided at both the top and bottom inside the sliding cavity 53. A plurality of connecting rods 55 are provided between the sliding ring 52 and the adjusting seat 51.

[0033] The angle adjustment mechanism 5 further includes a mounting seat 56. A rotating rod 57 is provided inside the mounting seat 56. The rotating rod 57 can rotate inside the mounting seat 56. A connecting plate 58 is fixedly connected to the connection part on the right side wall of the rotating rod 57. A connecting column 59 is fixedly connected to the top of the connecting plate 58. A sleeve 510 is fixedly connected to the left side wall of the rotating rod 57. A sliding sphere 511 is fixedly connected to the back side wall of the sleeve 510. The sliding sphere 511 is connected to the inside of the sliding cavity 53. Since the up and down movement of the adjusting seat 51 will drive the sliding ring 52 and the sliding cavity 53 to move up and down synchronously, and since the position of the sliding cavity 53 changes, at this time, the sliding sphere 511 inside the sliding cavity 53 will, after receiving the upward force of the sliding cavity 53, drive the sleeve 510 at the connection part of the sliding sphere 511 to synchronously drive the rotating rod 57 to rotate inside the mounting seat 56. Since the rotation of the rotating rod 57 will drive the connecting plate 58 and the connecting column 59 to rotate, and since the explosion-proof gas spectral imager body 6 is fixedly installed on the connecting column 59, it will drive the explosion-proof gas spectral imager body 6 to adjust the pitching angle.

[0034] The fixed ring 44 is fixedly connected to the adjusting seat 51. The peripheral walls inside the adjusting seat 51 are connected to the four sliding blocks 33.

[0035] The top of the driving motor 21 is fixedly connected to the mounting seat 56. The driving motor 21 can drive the mounting seat 56 to rotate, so as to drive the sliding sphere 511 to slide inside the sliding ring 52.

[0036] Workflow of the utility model: Step 1, when rotation is required, the drive motor 21 directly drives the output shaft 22 to rotate. Since the output shaft 22 is not connected to the fixed seat 31, as the output shaft 22 rotates, it drives the mounting seat 56 and the components located on the mounting seat 56 to rotate synchronously. During the rotation, the sliding sphere 511 slides inside the sliding cavity 53, thereby forming a limit and driving the explosion-proof gas spectral imager body 6 to perform horizontal rotation adjustment.

[0037] Step 2, when it is necessary to achieve pitch angle adjustment while performing horizontal rotation adjustment, the extension of the air rod 41 drives the connecting piece 43 and the fixed ring 44 to move. Since the fixed ring 44 is fixedly installed on the adjusting seat 51, it can drive the adjusting seat 51 to slide on the sliding block 33, realizing the up and down movement of the adjusting seat 51. Since the up and down movement of the adjusting seat 51 drives the sliding ring 52 and the sliding cavity 53 to move up and down synchronously, and the position of the sliding cavity 53 changes, at this time, after the sliding sphere 511 inside the sliding cavity 53 receives the upward force of the sliding cavity 53, the sleeve 510 at the connection of the sliding sphere 511 drives the rotating rod 57 to rotate inside the mounting seat 56 synchronously. Since the rotation of the rotating rod 57 drives the connecting plate 58 and the connecting column 59 to rotate, and since the explosion-proof gas spectral imager body 6 is fixedly installed on the connecting column 59, it will drive the explosion-proof gas spectral imager body 6 to perform pitch angle adjustment. It should be noted that the mounting seat 56 is directly fixed on the output shaft 22. Therefore, the rotating structure 2 can drive the explosion-proof gas spectral imager body 6 to rotate alone, and the drive of the lifting structure 4 will drive the angle adjustment mechanism 5 to rotate alone, so as to realize the simultaneous adjustment of rotation and angle.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
