Description

Technical Field

[0001] The present invention relates to the field of temperature detection devices, and more specifically, to a temperature detection device for a high-speed rotating plate vibrating under the action of a fluid. Background Art

[0002] A high-speed rotating plate is an important industrial and scientific research device, widely used in aero-engines, large mechanical equipment, and various rotating machinery. During operation, the temperature of the high-speed rotating plate will change due to factors such as rotational speed, friction, ambient temperature, and material properties. Therefore, advanced temperature measurement technologies and monitoring systems are required to accurately measure and control the temperature of the high-speed rotating plate; In the prior art, methods such as thermocouple temperature measurement method, infrared radiation temperature measurement method, and fiber Bragg grating sensor temperature measurement method are usually used to measure the temperature of the rotating plate. For example, a Chinese patent with the publication number CN207923298U discloses a thermocouple temperature measurement device, which makes the test object and the temperature measurement chamber more fixed by setting a fixed groove, thereby reducing the probability of the test object shifting during the test process and improving the stability of the temperature detection process; Although the thermocouple temperature measurement method in the prior art can conveniently measure the temperature of the test object, when measuring the temperature of a high-speed rotating plate, the high-speed rotating plate needs to rotate at different speeds. During the high-speed rotation of the rotating plate, non-linear vibration will occur, and the vibration will be transmitted to the thermocouple, causing the thermocouple to vibrate. The vibration of the thermocouple will not only cause a large error in the distance between the thermocouple and the rotating plate, affecting the stable detection accuracy, but also increase the risk of the thermocouple loosening and falling off over a long time, which will further affect the operation stability of the detection device.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 9 , a temperature detection device for a high-speed rotating plate vibrating under the action of a fluid, including a detection cylinder 12, a fixed seat 21 and a driving rod 15. An upper part of the outer surface of the driving rod 15 is fixedly connected with a supporting plate 26. A rotating plate 23 is sleeved on the outer surface of the driving rod 15. The lower outer surface of the rotating plate 23 is in close contact with the upper end of the supporting plate 26. An upper part of the inner surface of the detection cylinder 12 is fixedly connected with a retaining ring 22. A detection component is arranged inside the detection cylinder 12. The detection component includes a fixing frame 24 fixedly connected to the outer surface of the retaining ring 22. A notch 49 is formed through the outer surface of the fixing frame 24. An active block 34 is slidably connected to the inner surface of the notch 49. A guiding groove 50 is formed on the outer surface of the fixing frame 24 near the rotating plate 23. A sliding rod 35 is fixedly connected to the outer surface of the active block 34. The sliding rod 35 passes through to the outside of the fixing frame 24 through the guiding groove 50. A sliding sleeve 36 is threadedly connected to the outer surface of the sliding rod 35. One end of the outer surface of the sliding sleeve 36 away from the active block 34 is fixedly connected with a temperature sensor 38. The number of the fixing frames 24 is several groups and is distributed in a circular array.

[0020] A sliding groove 52 is formed inside the sliding sleeve 36. A traction strip 37 is fixedly connected to the inner surface of the sliding groove 52 near the temperature sensor 38. One end of the traction strip 37 away from the temperature sensor 38 is fixedly connected with the sliding rod 35.

[0021] By adopting the above technical solution, the rotating plate 23 will vibrate under the action of centrifugal force and aerodynamic force during high-speed movement, and the vibration will cause dynamic changes in the temperature of the rotating plate 23. In order to quickly detect the temperature of the rotating plate 23, a detection component is provided. During operation, the rotating plate 23 is sleeved outside the driving rod 15, and the rotating plate 23 is supported by the supporting plate 26. After the rotating plate 23 is stably clamped, the driving rod 15 drives the rotating plate 23 to rotate at high speed. The detection cylinder 12 fixedly supports the fixing frame 24 through the retaining ring 22. The notch 49 on the surface of the fixing frame 24 is used for sliding and guiding the movable block 34. The movable block 34 tractionally supports the sliding rod 35. The sliding rod 35 is threadedly connected to the sliding sleeve 36 through the sliding groove 52. By rotating the sliding sleeve 36, the distance between the sliding sleeve 36 and the fixing frame 24 can be adjusted, so that the distance between the temperature sensor 38 and the rotating plate 23 can be adjusted, so that the distance between the temperature sensor 38 and the rotating plate 23 is maintained within an appropriate range. The temperature sensor 38 detects the temperature on the surface of the rotating plate 23 to monitor the temperature change during the high-speed movement of the rotating plate 23. Several groups of temperature sensors 38 are evenly distributed around the rotating plate 23, so that multiple groups of detection results can be obtained, so as to reduce the detection error and improve the temperature measurement accuracy of the rotating plate 23. The traction strip 37 inside the sliding sleeve 36 can apply a certain elastic force between the sliding rod 35 and the sliding sleeve 36. The traction strip 37 will be twisted during the rotation of the sliding sleeve 36. The elastic force of the traction strip 37 can keep the sliding sleeve 36 and the sliding rod 35 stable, reducing the probability of the sliding sleeve 36 loosening due to equipment vibration, and then being able to keep the position of the temperature sensor 38 stable, and then effectively improving the reliability of the detection equipment.

[0022] As Figure 3 shown in Figure 9 Figure, a clamping component is arranged outside the driving rod 15. The clamping component includes a pressing seat 25 that is in screw transmission connection with the driving rod 15. The lower outer surface of the pressing seat 25 is in fit contact with the upper end of the rotating plate 23. An installation groove 27 is formed on the upper outer surface of the supporting plate 26. A contact block 20 is fixedly connected to the lower inner surface of the installation groove 27. The contact block 20 is made of an elastic wear-resistant material. The upper outer surface of the contact block 20 is in fit contact with the lower surface of the rotating plate 23. Both the installation groove 27 and the contact block 20 are circular rings.

[0023] By adopting the above technical solution, after the rotating plate 23 is sleeved outside the driving rod 15, the pressing seat 25 is rotated along the surface of the driving rod 15. Since the pressing seat 25 is in screw drive connection with the driving rod 15, it will move downward synchronously during the rotation. During the movement of the pressing seat 25, its lower surface will be in fitting contact with the upper end of the rotating plate 23. By cooperating with the supporting plate 26, the pressing seat 25 can squeeze and clamp the rotating plate 23, so that the rotating plate 23 can be kept stable. The mounting groove 27 formed on the surface of the supporting plate 26 is used to place the contact block 20. Under the action of the extrusion force, the contact block 20 will be in close fit with the surface of the rotating plate 23, so that the friction between the supporting plate 26 and the rotating plate 23 can be increased, and further the clamping stability of the rotating plate 23 can be effectively improved, which helps to further reduce the detection error.

[0024] As Figure 5 , Figure 6 , Figure 8 and Figure 9 shown, an adjusting assembly is arranged outside the fixing frame 24. The adjusting assembly includes an adjusting rod 33 rotatably connected to the outside of the fixing frame 24. A retaining wheel 32 is fixedly connected to the upper end of the adjusting rod 33. A connecting frame 14 is snap-fitted to the outer surface of the upper end of the detection cylinder 12. The connecting frame 14 has an L-shaped structure. A rotating sleeve 28 is fixedly connected to the end of the connecting frame 14 away from the detection cylinder 12.

[0025] The outer surface of the rotating sleeve 28 is rotatably connected with a movable plate 29. Both the rotating sleeve 28 and the movable plate 29 are annular. A retaining block 31 is fixedly connected to the outer surface of the upper end of the movable plate 29. The number of the retaining blocks 31 is several groups and they are distributed in an annular array. The outer surface of the retaining wheel 32 is in snap-fitting contact with the retaining blocks 31. The number of the connecting frames 14 is several groups and they are staggered with the fixing frame 24. A limiting rod 30 is slidably connected to the outer surface of the upper end of the movable plate 29. The lower end of the limiting rod 30 penetrates to the lower side of the movable plate 29 and is in snap-fitting contact with the rotating sleeve 28.

[0026] By adopting the above technical solution, during the testing process, in order to detect the temperatures at different positions of the rotating plate 23, an adjusting component is provided. A plurality of sets of connecting frames 14 are snap-connected to the upper end of the detection cylinder 12, so as to facilitate the flexible disassembly of the connecting frames 14 when the rotating plate 23 is installed. The connecting frames 14 support and lift the rotating sleeve 28. When adjusting the position of the temperature sensor 38, the operator rotates the movable plate 29 on the surface of the rotating sleeve 28. The movable plate 29 is in damping rotational connection with the rotating sleeve 28 and will remain stationary without external force. The movable plate 29 drives the stopper 31 on its surface to perform a circular motion. During the movement of the stopper 31, it will engage and contact the stopper wheel 32. The stopper 31 drives the stopper wheel 32 to rotate. During the rotation of the stopper wheel 32, it will drive the adjusting rod 33 to rotate synchronously. The movable block 34 is in screw drive connection with the adjusting rod 33. As the adjusting rod 33 rotates, it will drive the movable block 34 to move synchronously, so that the position of the temperature sensor 38 can be adjusted by the movable block 34, and thus the temperatures at different positions of the rotating plate 23 can be detected and analyzed, so as to better test and analyze the temperature characteristics of the rotating plate 23.

[0027] As Figure 5 shown in Figure 7 As shown, the fixed seat 21 is located outside the driving rod 15, and a guiding component is arranged outside the fixed seat 21. The guiding component includes a connecting seat 39 fixedly connected to the outer surface of the fixed seat 21. A receiving groove 51 is formed on the outer surface of the connecting seat 39 away from the fixed seat 21. An activity frame 40 is slidably connected to the inner surface of the receiving groove 51. The number of the activity frames 40 is two groups, and the number of the connecting seats 39 is several groups and is distributed in a circular array.

[0028] A limiting plate 41 is fixedly connected to the lower part of the inner surface of the activity frame 40. A core shaft 42 is fixedly connected to the outer surface of the limiting plate 41. A ball 43 is rotatably connected to the outer surface of the core shaft 42. The ball 43 is in rolling contact with the lower outer surface of the rotating plate 23. A cavity 44 is embedded and formed inside the connecting seat 39. One end of the activity frame 40 away from the limiting plate 41 penetrates into the cavity 44.

[0029] By adopting the above technical solution, the fixed seat 21 is used to fixedly support the connecting seat 39. The receiving groove 51 on the surface of the connecting seat 39 is used to slidably support the activity frame 40. The activity frame 40 fixedly supports the core shaft 42 through the limiting plate 41, so as to rotatably support the ball 43 through the core shaft 42. During the rotation of the rotating plate 23, its inner surface will be in rotational contact with the surface of the ball 43. The rotating plate 23 can be rotationally guided through the ball 43, so that the movement of the rotating plate 23 is more stable, so that the vibration amplitude of the rotating plate 23 is maintained within an appropriate range, and the distance between the rotating plate 23 and the temperature sensor 38 can also be kept stable, thereby further improving the temperature detection accuracy of the rotating plate 23.

[0030] As shown in Figure 7 the figure, a control component is arranged inside the cavity 44. The control component includes a piston plate 45 slidably connected to the inner surface of the cavity 44. One end of the movable frame 40 away from the ball 43 is fixedly connected to the piston plate 45. A middle part of the inner surface of the cavity 44 is fixedly connected with an elastic membrane 46. A lower end of the inner surface of the cavity 44 is fixedly connected with a pressure sensor 47. One end of the inner surface of the cavity 44 away from the movable frame 40 is fixedly connected with a displacement sensor 48. The ball 43 is made of a thermal expansion material.

[0031] By adopting the above technical solution, the ball 43 is made of a thermal expansion material. During the rolling contact between the ball 43 and the rotating plate 23, when the temperature of the rotating plate 23 changes, the temperature of the ball 43 also changes accordingly. At this time, the volume of the ball 43 will also change with the temperature. When the rotating plate 23 steadily rises, the temperature of the ball 43 rises accordingly, causing its volume to increase. At this time, the distance between the core shaft 42 and the rotating plate 23 will also increase. The movable frame 40 is pushed into the cavity 44 by the core shaft 42 and the limiting plate 41. During the movement of the movable frame 40, the piston plate 45 will be pushed. During the movement of the piston plate 45 towards the fixed seat 21, the gas inside the cavity 44 will be squeezed, so that the elastic membrane 46 is elastically deformed towards the side away from the piston plate 45 by the gas. At this time, the distance between the elastic membrane 46 and the displacement sensor 48 will change accordingly, so as to detect the displacement amount of the elastic membrane 46 according to the displacement sensor 48. At the same time, the pressure on the other side of the elastic membrane 46 inside the cavity 44 will increase, and the air pressure inside the cavity 44 is detected and fed back by the pressure sensor 47. Then, the deformation amount of the elastic membrane 46 and the air pressure change value are input into the calculation model to measure the temperature change of the rotating plate 23. By detecting the temperature of the rotating plate 23 in different ways, it is convenient to conduct a better control experiment, so that the detection error can be further reduced in combination with the temperature sensor 38, and the operation stability of the detection device can be improved while effectively improving the temperature detection accuracy.

[0032] As shown in Figure 3 and Figure 4 the figure, a placing seat 11 is fixedly connected to the lower end of the detection cylinder 12. The lower end of the placing seat 11 is in an open shape. A connecting plate 18 is fixedly connected to the inner surface of the detection cylinder 12. One side of the connecting plate 18 away from the detection cylinder 12 is fixedly connected with a fixing plate 16. An electric motor 17 is fixedly connected to the outer surface of the lower end of the fixing plate 16. The upper end of the output shaft of the electric motor 17 is fixedly connected with a driving rod 15.

[0033] The outer surface of the upper end of the fixing plate 16 is fixedly connected with a support plate 19. The upper outer surface of the support plate 19 is fixedly connected with the lower end of the fixed seat 21. The support plate 19 is arc-shaped. The number of the support plates 19 is several groups and they are distributed in a circular array outside the driving rod 15. The outer surface of the detection cylinder 12 is provided with air guide grooves 13. The number of the air guide grooves 13 is several groups and they are distributed in a circular array.

[0034] The temperature sensor 38, the air pressure sensor 47 and the displacement sensor 48 are all electrically connected to the temperature detection equipment control system.

[0035] By adopting the above technical solution, the placement seat 11 is used to support the detection cylinder 12. The air guide grooves 13 on the surface of the detection cylinder 12 can ensure the circulation of the gas inside and outside the detection cylinder 12, so that the gas resistance received during the rotation of the rotating plate 23 can be kept stable. The detection cylinder 12 fixedly supports the fixing plate 16 through the connecting plate 18, so as to fixedly support the motor 17 through the fixing plate 16. The driving rod 15 is driven to rotate at a high speed by the output shaft of the motor 17. The fixing plate 16 supports the fixed seat 21 through the support plate 19, so that the fixed seat 21 can be kept stable during the detection process, which helps to improve the stability of the detection equipment.

[0036] Usage method: When detecting the temperature of the rotating plate 23, first, the rotating plate 23 is sleeved outside the driving rod 15. The rotating plate 23 can be squeezed and clamped through the cooperation of the pressing seat 25 and the supporting plate 26. The output shaft of the motor 17 drives the driving rod 15 to rotate at high speed, thereby driving the rotating plate 23 to rotate at high speed. The detection cylinder 12 fixedly supports the fixing frame 24 through the retaining ring 22, traction-supports the sliding rod 35 through the movable block 34, and detects the temperature on the surface of the rotating plate 23 through the temperature sensor 38 to monitor the temperature change during the high-speed movement of the rotating plate 23. As the adjusting rod 33 rotates, it will drive the movable block 34 to move synchronously, so that the temperature sensor 38 can be driven by the movable block 34 to adjust its position, and thus the temperature at different positions of the rotating plate 23 can be detected and analyzed. During the rotation of the rotating plate 23, its inner surface will be in rotational contact with the surface of the ball 43, which can guide the rotation of the rotating plate 23 and make the movement of the rotating plate 23 more stable. When the temperature of the rotating plate 23 rises steadily, the temperature of the ball 43 rises accordingly, causing its volume to increase. The core shaft 42 and the limiting plate 41 drive the movable frame 40 to be pushed into the cavity 44. During the movement of the piston plate 45 towards the fixed seat 21, the gas inside the cavity 44 will be squeezed, so that the elastic membrane 46 is elastically deformed towards the side away from the piston plate 45 by the gas. The displacement sensor 48 detects the displacement of the elastic membrane 46. At the same time, the pressure on the other side of the elastic membrane 46 inside the cavity 44 will increase, and the air pressure sensor 47 detects and feeds back the air pressure inside the cavity 44. While improving the operation stability of the detection device, the temperature detection accuracy can also be effectively improved.
