Description

Technical Field

[0001] The present invention relates to the field of temperature detection equipment, and more particularly to a temperature detection equipment when a high-speed rotating plate vibrates under the action of a fluid. Background Art

[0002] High-speed rotating plates are important industrial and scientific research equipment, widely used in aircraft engines, large-scale mechanical equipment, and various types of rotating machinery. During operation, high-speed rotating plates are affected by factors such as rotation speed, friction, ambient temperature, and material properties, causing their temperature to change accordingly. Therefore, advanced temperature measurement technology and monitoring systems are required to accurately measure and control the temperature of high-speed rotating plates.

[0003] In the prior art, the temperature of the rotating plate is usually measured using methods such as thermocouple temperature measurement, infrared radiation temperature measurement, and fiber Bragg grating sensor temperature measurement. For example, Chinese patent publication No. CN207923298U discloses a thermocouple temperature measurement device that provides a fixed groove to further secure the test object and the temperature measurement chamber, thereby reducing the probability of the test object shifting during the test process and improving the stability of the temperature detection process.

[0004] Although the thermocouple temperature measurement method in the existing technology can conveniently measure the temperature of the test object, when measuring the temperature of the high-speed rotating plate, it is necessary to rotate the high-speed rotating plate at different speeds. The rotating plate will produce nonlinear vibrations during high-speed rotation, and the vibration will be transmitted to the thermocouple, causing the thermocouple to vibrate to a certain extent. 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 long-term vibration will increase the risk of the thermocouple loosening and falling, thereby affecting the operational stability of the detection equipment.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 A temperature detection device for a high-speed rotating plate vibrating under the action of a fluid comprises a detection cylinder 12, a fixing seat 21, and a driving rod 15. The upper portion of the outer surface of the driving rod 15 is fixedly connected to a supporting plate 26. The outer surface of the driving rod 15 is sleeved with a rotating plate 23. The outer surface of the lower end of the rotating plate 23 is in contact with the upper end of the supporting plate 26. The upper portion of the inner surface of the detection cylinder 12 is fixedly connected to a retaining ring 22. A detection component is provided inside the detection cylinder 12.

[0037] By adopting the above technical solution, the rotating plate 23 will vibrate due to the centrifugal force and aerodynamic force under high-speed movement, and the vibration will cause the temperature of the rotating plate 23 to change dynamically. In order to quickly detect the temperature of the rotating plate 23, a detection component is set. During operation, the rotating plate 23 is sleeved on the outside of the driving rod 15, and the rotating plate 23 is lifted and supported by the supporting plate 26. After the rotating plate 23 is clamped and stabilized, the rotating plate 23 is driven to rotate at high speed by the driving rod 15. The detection cylinder 12 fixes and supports the fixed frame 24 through the retaining ring 22. The groove 49 on the surface of the fixed frame 24 is used to slide and guide the movable block 34. The sliding rod 35 is pulled and supported by the movable block 34. 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 fixed frame 24 can be adjusted, so that the temperature sensor 38 and the rotating plate are adjusted by the sliding sleeve 36. 23 is 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 is used to detect the temperature of 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 bar 37 inside the sleeve 36 can apply a certain elastic force between the slide rod 35 and the sleeve 36. The traction bar 37 will twist during the rotation of the sleeve 36. The elastic force of the traction bar 37 can keep the sleeve 36 and the slide rod 35 stable, reducing the chance of the sleeve 36 loosening due to equipment vibration, thereby keeping the position of the temperature sensor 38 stable, and effectively improving the reliability of the detection equipment.

[0038] like Figure 3 and Figure 9 As shown, a clamping assembly is provided on the outside of the driving rod 15, and the clamping assembly includes a pressure seat 25 which is spirally connected to the driving rod 15. The outer surface of the lower end of the pressure seat 25 is in contact with the upper end of the rotating plate 23. A mounting groove 27 is provided on the outer surface of the upper end of the support plate 26. The lower end of the inner surface of the mounting groove 27 is fixedly connected to a contact block 20. The contact block 20 is made of elastic and wear-resistant material. The outer surface of the upper end of the contact block 20 is in contact with the lower surface of the rotating plate 23. The mounting groove 27 and the contact block 20 are both annular.

[0039] By adopting the above technical solution, after the rotating plate 23 is sleeved on the outside of the driving rod 15, the pressure seat 25 is rotated along the surface of the driving rod 15. The pressure seat 25 is connected to the driving rod 15 through a spiral transmission and will move downward synchronously during the rotation process. During the movement, the lower surface of the pressure seat 25 will be in contact with the upper end of the rotating plate 23. The pressure seat 25 cooperates with the support plate 26 to squeeze and clamp the rotating plate 23, so that the rotating plate 23 can remain stable. The mounting groove 27 opened on the surface of the support plate 26 is used to place the contact block 20. Under the action of the extrusion force, the contact block 20 will remain in close contact with the surface of the rotating plate 23, thereby increasing the friction between the support plate 26 and the rotating plate 23, and then effectively improving the clamping stability of the rotating plate 23, which helps to further reduce the detection error.

[0040] like Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, an adjustment component is provided on the outside of the fixing frame 24, and the adjustment component includes an adjustment rod 33 rotatably connected to the outside of the fixing frame 24, and the upper end of the adjustment rod 33 is fixedly connected to the blocking wheel 32, and the outer surface of the upper end of the detection cylinder 12 is engaged with the connecting frame 14, and the connecting frame 14 is an L-shaped structure. The end of the connecting frame 14 away from the detection cylinder 12 is fixedly connected to the rotating sleeve 28.

[0041] The outer surface of the rotating sleeve 28 is rotatably connected to a movable plate 29, and the rotating sleeve 28 and the movable plate 29 are both annular. A stopper 31 is fixedly connected to the outer surface of the upper end of the movable plate 29. The stoppers 31 are in several groups and distributed in a ring array. The outer surfaces of the stop wheels 32 are engaged with the stoppers 31. The number of the connecting frames 14 is in several groups and is staggered with the fixed frame 24. The outer surface of the upper end of the movable plate 29 is slidably connected to a limiting rod 30, and the lower end of the limiting rod 30 passes through the lower side of the movable plate 29 and is engaged with the rotating sleeve 28.

[0042] By adopting the above technical solution, in order to detect the temperature at different positions of the rotating plate 23 during the test, an adjustment component is set, and several groups of connecting frames 14 are snap-connected to the upper end of the detection cylinder 12, so that the connecting frame 14 can be flexibly disassembled when the rotating plate 23 is installed. The connecting frame 14 supports 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 and the rotating sleeve 28 are connected by a damping rotation. When there is no external force, it will remain stationary and be driven by the movable plate 29. The stopper 31 on the surface makes a circular motion. The stopper 31 will engage with the stop wheel 32 during the movement, and the stopper 31 drives the stop wheel 32 to rotate. The stop wheel 32 drives the adjusting rod 33 to rotate synchronously during the rotation. The movable block 34 is connected to the adjusting rod 33 through a spiral transmission. As the adjusting rod 33 rotates, the movable block 34 will be driven to move synchronously, so that the temperature sensor 38 can be driven by the movable block 34 to adjust the position, so that the temperature 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.

[0043] like Figure 5 and Figure 7 As shown, the fixed seat 21 is located on the outside of the driving rod 15, and a guide assembly is provided on the outside of the fixed seat 21. The guide assembly includes a connecting seat 39 fixedly connected to the outer surface of the fixed seat 21, and a receiving groove 51 is provided on the outer surface of the connecting seat 39 away from the fixed seat 21. The inner surface of the receiving groove 51 is slidably connected to a movable frame 40. The number of the movable frames 40 is two groups, and the number of the connecting seats 39 is several groups and distributed in a ring array.

[0044] The lower part of the inner surface of the movable frame 40 is fixedly connected to the limiting plate 41, the outer surface of the upper end of the limiting plate 41 is fixedly connected to the core shaft 42, the outer surface of the core shaft 42 is rotatably connected to the ball 43, and the ball 43 is in rolling contact with the outer surface of the lower end of the rotating plate 23. A cavity 44 is embedded in the inner side of the connecting seat 39, and the end of the movable frame 40 away from the limiting plate 41 passes through the interior of the cavity 44.

[0045] By adopting the above technical solution, the fixed seat 21 is used to fix the connecting seat 39, and the storage groove 51 on the surface of the connecting seat 39 is used to slide and support the movable frame 40. The movable frame 40 fixes and supports the core shaft 42 through the limit plate 41, thereby supporting the ball 43 in rotation through the core shaft 42. During the rotation process, the inner surface of the rotating plate 23 will be in rotational contact with the surface of the ball 43. The ball 43 can guide the rotation of the rotating plate 23, making the movement of the rotating plate 23 more stable, thereby maintaining the vibration amplitude of the rotating plate 23 within an appropriate range, and also keeping the distance between the rotating plate 23 and the temperature sensor 38 stable, thereby further improving the temperature detection accuracy of the rotating plate 23.

[0046] like Figure 7 As shown, a control component is provided inside the cavity 44, and the control component includes a piston plate 45 slidably connected to the inner surface of the cavity 44, and the movable frame 40 is fixedly connected to the piston plate 45 at one end away from the ball 43. An elastic membrane 46 is fixedly connected to the middle of the inner surface of the cavity 44, and an air pressure sensor 47 is fixedly connected to the lower end of the inner surface of the cavity 44. A displacement sensor 48 is fixedly connected to the end of the inner surface of the cavity 44 away from the movable frame 40, and the ball 43 is made of thermal expansion material.

[0047] By adopting the above technical solution, the ball 43 is made of 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. At this time, the volume of the ball 43 also changes with the temperature change. When the rotating plate 23 rises steadily, the temperature of the ball 43 rises accordingly, thereby increasing its volume. At this time, the distance between the core shaft 42 and the rotating plate 23 also increases. The core shaft 42 and the limit plate 41 drive the movable frame 40 to push into the cavity 44. The movable frame 40 pushes the piston plate 45 during the movement. The piston plate 45 squeezes the gas inside the cavity 44 during the movement toward the side of the fixed seat 21, thereby pushing the elastic membrane 4 through the gas. 6 elastically deforms toward the side away from the piston plate 45. At this time, the distance between the elastic membrane 46 and the displacement sensor 48 will change accordingly, so that the displacement of the elastic membrane 46 is detected according to the displacement sensor 48. At the same time, the pressure inside the cavity 44 on the other side of the elastic membrane 46 will increase, and the air pressure inside the cavity 44 is detected and fed back by the air 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 calculate the temperature change of the rotating plate 23. By adopting different methods to detect the temperature of the rotating plate 23, 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, the operating stability of the detection equipment can be improved, and the temperature detection accuracy can also be effectively improved.

[0048] like Figure 3 and Figure 4 As shown, the lower end of the detection cylinder 12 is fixedly connected to the placement seat 11, the lower end of the placement seat 11 is open, the inner surface of the detection cylinder 12 is fixedly connected to the connecting plate 18, the side of the connecting plate 18 away from the detection cylinder 12 is fixedly connected to the fixing plate 16, the outer surface of the lower end of the fixing plate 16 is fixedly connected to the motor 17, and the upper end of the output shaft of the motor 17 is fixedly connected to the driving rod 15.

[0049] The outer surface of the upper end of the fixing plate 16 is fixedly connected to a support plate 19, and the outer surface of the upper end of the support plate 19 is fixedly connected to the lower end of the fixing seat 21. The support plate 19 is arc-shaped, and the number of the support plates 19 is several groups and distributed in a ring array outside the driving rod 15. The outer surface of the detection cylinder 12 is provided with an air guide groove 13, and the number of the air guide grooves 13 is several groups and distributed in a ring array.

[0050] 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.

[0051] By adopting the above technical solution, the placement seat 11 is used to lift and support the detection cylinder 12. The air guide groove 13 on the surface of the detection cylinder 12 can ensure the circulation of gas inside and outside the detection cylinder 12, so that the gas resistance encountered by the rotating plate 23 during the rotation can remain stable. The detection cylinder 12 fixes and supports the fixed plate 16 through the connecting plate 18, and thus fixes and supports the motor 17 through the fixed plate 16. The output shaft of the motor 17 drives the drive rod 15 to rotate at high speed. The fixed plate 16 lifts and supports the fixed seat 21 through the support plate 19, so that the fixed seat 21 remains stable during the detection process, which helps to improve the stability of the detection equipment.

[0052] Instructions for use: When detecting the temperature of the rotating plate 23, first, the rotating plate 23 is sleeved on the outside of the driving rod 15, and the rotating plate 23 can be squeezed and clamped by cooperating with the pressure seat 25 and the supporting plate 26. The driving rod 15 is driven to rotate at high speed by the output shaft of the motor 17, thereby driving the rotating plate 23 to rotate at high speed. The detection cylinder 12 fixes and supports the fixing frame 24 through the retaining ring 22, and pulls and supports the sliding rod 35 through the movable block 34. The temperature of the surface of the rotating plate 23 is detected by 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, the movable block 34 will be driven to move synchronously, so that the temperature sensor 38 can be driven by the movable block 34 to adjust the position, so that the temperature at different positions of the rotating plate 23 can be detected and analyzed. During the rotation of the rotating plate 23, the temperature inside the rotating plate 23 is adjusted. The surface will be in rotational contact with the surface of the ball 43, and the rotation of the rotating plate 23 can be guided to make the movement of the rotating plate 23 more stable. When the rotating plate 23 rises steadily, the temperature of the ball 43 rises accordingly, thereby increasing its volume. The movable frame 40 is driven to push into the cavity 44 through the core shaft 42 and the limit plate 41. During the movement of the piston plate 45 toward the side of the fixed seat 21, the gas inside the cavity 44 will be squeezed, thereby pushing the elastic membrane 46 to the side away from the piston plate 45 through the gas to undergo elastic deformation. The displacement sensor 48 detects the displacement of the elastic membrane 46. At the same time, the pressure inside the cavity 44 on the other side of the elastic membrane 46 will increase. The air pressure inside the cavity 44 is detected and fed back through the air pressure sensor 47, which can improve the operating stability of the detection equipment while also effectively improving the temperature detection accuracy.
