Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0042] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0043] like Figure 1 and Figure 9 As shown, the measuring device is used to measure thermal insulation materials, and the ablation amount measuring device includes:
[0044] Laser measurement component 1, rotating component 2 and positioning component 3, the laser measurement component 1 is fixed on the rotating component 2, the rotating component 2 rotates around the first rotating axis, the positioning component 3 includes a rotation sensor 31 and an optical displacement sensor 32, the rotation sensor 31 is installed on the rotating component 2, and the optical displacement sensor 32 is installed on the laser measurement component 1.
[0045] The supporting platform 4 is arranged on one side of the laser measurement component 1 in the first direction and is located in the irradiation direction of the laser measurement component 1, wherein the first direction intersects the direction of the plane where the supporting platform 4 is located, and the first direction coincides with the extension direction of the first rotation axis.
[0046] The housing assembly 5 includes an assembly cavity, and the laser measurement assembly 1, the rotation assembly 2 and the supporting platform 4 are all installed in the assembly cavity.
[0047] As can be seen from the above embodiment, in the embodiment of the present utility model, since the laser measurement component 1 is fixed to the rotating component 2, the rotating component 2 rotates about the first rotation axis, and the positioning component 3 includes a rotation sensor 31 and an optical displacement sensor 32, with the rotation sensor 31 mounted on the rotating component 2 and the optical displacement sensor 32 mounted on the laser measurement component 1, the laser measurement component 1 can rotate synchronously with the rotating component 2 about the first rotation axis, thereby enabling the laser measurement component 1 to rotate in different directions, thereby enabling the laser measurement component 1 to have measurement angles in different directions and at different positions. In addition, the positioning component 3 includes the rotation sensor 31 and the optical displacement sensor 32, with the rotation sensor 31 mounted on the rotating component 2 and the optical displacement sensor 32 mounted on the laser measurement component 1, thereby ensuring that the rotation of the laser measurement component 1 and the rotation of the rotating component 2 are accurately controllable. Since the supporting platform 4 is arranged on one side of the laser measurement component 1 in the first direction and is located in the irradiation direction of the laser measurement component 1, the first direction and the direction of intersection of the plane where the supporting platform 4 are located, and the first direction and the extension direction of the first rotation axis coincide with each other, the thermal insulation material arranged on the supporting platform 4 can be measured with high precision by the laser measurement component 1 and the precise control of the rotating component 2, thereby realizing the high-precision measurement requirements of the thermal insulation material. In summary, the ablation amount measuring device provided by the embodiment of the present invention can utilize the laser measurement component 1 to irradiate the surface of the thermal insulation material, and the ablation condition of the thermal insulation material can be inferred by the reflection or scattering characteristics of the measurement laser beam of the laser measurement component 1. The laser measurement component 1 can measure the thickness change of the thermal insulation material in a non-contact manner, and the laser beam of the laser measurement component 1 has extremely high accuracy, and can achieve micron-level or even nanometer-level measurement without contacting the thermal insulation material being measured, thereby avoiding damage or contamination to the thermal insulation material being measured. At the same time, the rotating component 2 can enable the laser measurement component 1 to have measurement angles in different directions and positions, that is, the measurement range of the laser measurement component 1 can be unrestricted, which can further improve the measurement accuracy of the ablation amount measuring device. Moreover, since the structure of the ablation amount measuring device provided by the embodiment of the present invention is relatively simple, the production and preparation cost of the ablation amount measuring device is reduced.
[0048] In the above embodiment, the rotating assembly 2 can be any structure capable of achieving rotational motion, such as a motor shaft structure, a motor gear structure, or a motor screw structure, and the present invention is not limited thereto. The laser measurement assembly 1 includes a laser transmitter and a laser receiver. The laser transmitter is a laser product capable of generating and emitting a stable laser beam, and the receiver is used to capture the laser signal reflected from the object being measured. To ensure the quality of the received signal, the receiver uses a highly sensitive photoelectric conversion device that can effectively convert the received optical signal into an electrical signal for subsequent analysis and processing by a signal processor.
[0049] Rotation sensor 31 can be any of a mechanical sensor, an optical rotation sensor, a magnetic rotation sensor 1, or a magnetic induction rotation sensor. It can detect the rotation of rotating assembly 2 in real time, facilitating real-time detection and control of the measurement range of laser measurement assembly 1. Optical displacement sensor 32, a sensor based on the photoelectric effect and position transformation principles, can accurately measure changes in the position between laser measurement assembly 1 and the insulating material, thereby ensuring the accuracy of their relative position during measurement.
[0050] The support platform 4 can be a cylindrical, conical, or truncated cone-shaped structure having at least one circular surface, and this is not limited to this embodiment of the present invention. The circular surface of the support platform 4 can be a placement surface for the thermal insulation material. During installation, the support platform 4 needs to be positioned to one side of the laser measurement assembly 1 in the first direction and in the irradiation direction of the laser measurement assembly 1. That is, the support platform 4 can be used to position the thermal insulation material directly opposite the laser measurement assembly 1.
[0051] The housing assembly 5 may be a housing structure having an assembly cavity. The housing assembly 5 may be cylindrical, square, or have other shapes, which are not limited in the present embodiment. The laser measurement assembly 1, the rotation assembly 2, and the support platform 4 may be mounted in the assembly housing by welding, threading, or hole-shaft fitting.
[0052] The following embodiment will specifically introduce the structure of the ablation amount measuring device provided by the embodiment of the utility model, as follows:
[0053] In some embodiments, the shell assembly 5 includes an inner shell 51 and an outer shell 52; the outer shell 52 is a closed shell structure, the inner shell 51 is detachably connected to the outer shell 52, and the laser measurement assembly 1, the rotation assembly 2 and the support platform 4 are all installed in the cavity of the inner shell 51.
[0054] In this embodiment, since the outer shell 52 is a sealed shell structure, the inner shell 51 is detachably connected to the outer shell 52, and the laser measurement component 1, the rotating component 2, and the supporting platform 4 are all installed in the cavity of the inner shell 51, the outer shell 52 can form a relatively closed space, and the outer shell 52 can play a certain buffering role against changes in the external environment, and at the same time, the outer shell 52 can shield the light in the external environment. In this way, changes in external temperature, humidity, and other environmental factors such as light will not affect the measurement accuracy of the laser measurement component 1. At the same time, if the ablation measurement device is used in a harsh working environment, such as when the ablation measurement device is used in a working environment with dust or other pollutants, the outer shell 52 can prevent these harmful substances from directly contacting the measurement device, thereby extending the service life of the device. It should be noted that the outer shell 52 and the inner shell 51 can be connected by a detachable connection method such as threaded connection, plug-in connection, riveting, etc., which is not limited in this embodiment of the utility model.
[0055] Regarding the connection between the outer shell 52 and the inner shell 51, in some embodiments, a first connecting tube 521 is provided on the inner wall of the outer shell 52, and a second connecting tube 511 is provided on the outer surface of the inner shell 51; the axis of the first connecting tube 521 and the axis of the second connecting tube 511 intersect, and the first connecting tube 521 is inserted into the second connecting tube 511.
[0056] In this embodiment, since the inner wall of the outer shell 52 is provided with a first connecting tube 521 and the outer surface of the inner shell 51 is provided with a second connecting tube 511, the axis of the first connecting tube 521 and the axis of the second connecting tube 511 intersect, and the first connecting tube 521 is inserted into the second connecting tube 511, the outer shell 52 and the inner shell 51 can be detachably connected by the insertion of the first connecting tube 521 and the second connecting tube 511. By prefabricating the first connecting tube 521 and the second connecting tube 511, the connection between the outer shell 52 and the inner shell 51 can be conveniently achieved, reducing the complexity and difficulty of installation, and reducing the installation cost of the shell assembly 5. While the outer shell 52 and the inner shell 51 are assembled, the load can be transferred and dispersed through the first connecting tube 521 and the second connecting tube 511, thereby enhancing the overall stability and strength of the entire shell assembly 5.
[0057] In some embodiments, the inner shell 51 includes a cylinder 512 and a cover 513; the cylinder 512 has openings at both ends, the cover 513 covers the opening at one end of the cylinder 512, and the supporting platform 4 is located at the opening at the other end of the cylinder 512. A closed cavity is formed between the cover 513 and the supporting platform 4, and the laser measurement component 1, the rotating component 2 and the supporting platform 4 are all installed in the closed cavity.
[0058] In this embodiment, since the supporting platform 4 is located at the opening at the other end of the cylinder 512, a closed cavity is formed between the cover 513 and the supporting platform 4, and the laser measurement component 1, the rotating component 2 and the supporting platform 4 are all installed in the closed cavity. Therefore, a second shielding structure can be formed through the inner shell 51, and then the second shielding structure can further shield the changes in external temperature, humidity and environmental factors such as light, thereby further improving the accuracy of the measurement.
[0059] Furthermore, in some embodiments, the cylinder 512 is a cylindrical cylinder 512, the outer edge of the supporting platform 4 is circular, the outer edge of the supporting platform 4 contacts the inner wall of the cylinder 512, and the supporting platform 4 and the cylinder 512 are clearance-matched; the ablation amount measuring device includes a fine-tuning component 43, and the fine-tuning component 43 is connected to the supporting platform 4 to drive the supporting platform 4 to rotate along the first rotation axis or move along the first direction.
[0060] In this embodiment, since the outer edge of the carrier 4 is circular, the outer edge of the carrier 4 contacts the inner wall of the cylinder 512, and the carrier 4 and the cylinder 512 are in clearance fit, the carrier 4 can be rotated relative to the cylinder 512. In addition, since the ablation amount measuring device includes a fine-tuning component 43, the fine-tuning component 43 is connected to the carrier 4 to drive the carrier 4 to rotate along the first rotation axis or move along the first direction, the carrier 4 can be driven by the fine-tuning component 43 to rotate along the first rotation axis or move along the first direction, thereby achieving control of the relative position of the carrier 4 to achieve the accuracy of the placement position of the thermal insulation material. In one possible implementation method, the fine-tuning component 43 can include a rotating drive member, and the selected drive member can be any structure that can achieve rotational motion, such as a motor shaft structure, a motor gear structure, a motor screw structure, etc., and the embodiment of the utility model does not limit this. Furthermore, it should be noted that, in one possible implementation, the fine-tuning assembly 43 may include an axial drive member, which is drivably connected to the carrier 4. The axial drive member can change the axial distance between the carrier 4 and the laser measurement assembly 1. Thus, while the relative position of the laser measurement assembly 1 remains unchanged, the relative axial distance between the thermal insulation material and the laser measurement assembly 1 can be adjusted, thereby facilitating precise control of the thermal insulation material. The axial drive member can be any structure capable of achieving linear motion, such as a motor screw structure, a motor push rod structure, or a cylinder push rod structure, and this is not limited in the present embodiment.
[0061] Furthermore, an annular retaining ring structure 41 is provided on the outer edge of the surface of the support platform 4 facing the laser measurement assembly 1. Multiple positioning sensors 42 are provided on the inner wall of the annular retaining ring structure 41. These sensors 42 are used to detect the position of the thermal insulation material. The spacing between adjacent sensors 42 is equal.
[0062] In this embodiment, an annular retaining ring structure 41 is provided on the outer edge of the surface of the support platform 4 facing the laser measurement assembly 1; and multiple positioning sensors 42 are provided on the inner wall of the annular retaining ring structure 41. The positioning sensors 42 are used to detect the position of the thermal insulation material. Therefore, the placement position of the thermal insulation material can be detected in real time by the positioning sensors 42, that is, the relative position of the thermal insulation material and the support platform can be detected, thereby ensuring the accuracy of the placement position of the thermal insulation material and further improving the accuracy of the detection of the ablation measurement device. In addition, because the spacing between each adjacent two positioning sensors 42 is equal, the multiple positioning sensors 42 can be evenly distributed, further ensuring the accuracy of the relative position of the thermal insulation material support platform 4.
[0063] In some embodiments, the rotating assembly 2 includes a rotating base 21, a bracket 22, an angle rotation shaft 23 and a rotating drive motor 24, and the positioning assembly 3 also includes an angle sensor 33; the rotating base 21 is arranged on the surface of the cover body 513 facing the supporting platform 4, and a mounting hole is opened at the center of the rotating base 21, and the bracket 22 is installed in the mounting hole. The angle rotation shaft 23 is installed on the bracket 22, and the angle rotation shaft 23 is connected to the drive shaft of the rotating drive motor 24, the laser measurement assembly 1 is installed on the angle rotation shaft 23, and the angle sensor 33 is installed on the angle rotation shaft 23.
[0064] In this embodiment, the rotating base 21 can be a boss structure provided on the surface of the cover 513 facing the support platform 4. The bracket 22 is mounted on a mounting hole at the center of the rotating base 21, and the mounting hole can be used to limit the installation of the bracket 22. The bracket 22 can be a cross-shaped bracket 22 structure to facilitate the arrangement of other components on the bracket 22. Subsequently, the angle rotation shaft 23 can be mounted on the bracket 22. The angle rotation shaft 23 is connected to the drive shaft of the rotary drive motor 24, so that the angle rotation shaft 23 can rotate synchronously with the drive shaft of the rotary drive motor 24. In this way, the rotation of the rotary drive motor 24 can drive the rotation of the angle rotation shaft 23, and the laser measurement assembly 1 can rotate with the rotation of the angle rotation shaft 23. Since the angle sensor 33 is mounted on the angle rotation shaft 23, the angle sensor 33 can detect the rotation angle of the angle rotation shaft 23, thereby indirectly feeding back the rotation angle of the laser measurement assembly 1, thereby controlling the rotation angle of the laser measurement assembly 1 by controlling the rotation of the rotary drive motor 24. Thus, in this embodiment, the laser measurement component 1 can be rotated in any direction by controlling the driving motor to rotate clockwise or counterclockwise, thereby achieving the change of different rotation angles of the laser measurement component 1.
[0065] In other embodiments, a rotating shaft may be provided on the rotating base 21, and a first drive motor may be provided on the rotating shaft, so that the rotation of the first drive motor drives the rotating base 21 to rotate in a first rotation direction. The rotating base 21 is provided on the surface of the cover 513 facing the support platform 4. A mounting hole is provided at the center of the rotating base 21, and a bracket 22 is mounted in the mounting hole. An angular rotation shaft 23 is mounted on the bracket 22, and the angular rotation shaft 23 is connected to the drive shaft of the second drive motor. The laser measurement assembly 1 is mounted on the angular rotation shaft 23, so that the rotation of the second drive motor drives the angular rotation shaft 23 to rotate in a second rotation direction, wherein the first rotation direction and the second rotation direction are opposite rotation directions. In this way, the laser measurement assembly 1 can be indirectly driven to rotate in the first rotation direction by controlling the first drive motor to rotate in the first rotation direction through the rotation of the rotating base 21. The laser measurement assembly 1 can be driven to rotate in the second rotation direction by controlling the second drive motor to rotate in the second rotation direction through the rotation interval of the angular rotation shaft 23. Furthermore, rotation in different rotation directions can be achieved by controlling the rotation of the first drive motor or the second drive motor.
[0066] In some embodiments, the ablation amount measuring device also includes a control system 6, and a signal controller 7 and a signal adapter card 8 are provided on the surface of the bottom of the inner shell 51 facing the supporting platform 4; the signal controller 7 and the signal adapter card 8 are electrically connected to the control system 6 respectively, and the laser measurement component 1 is electrically connected to the signal controller 7.
[0067] It should be noted that the control system 6 may include a control mainboard, an image processing module, and a data processing module. The control mainboard may be a component that provides control signals. The control mainboard can provide control signals to the signal controller 7 and signal adapter card 8 to achieve signal control of the laser measurement component 1, the rotation component 2, and the positioning component 3. The control mainboard may also include a signal processor, which allows the control system 6 to automatically adjust the emission angle, frequency, and other parameters of the laser measurement component 1 based on measurement requirements to achieve optimal measurement results. The image processing module and the data processing module can amplify, filter, and digitize the received electrical signals to extract useful measurement information. The image processing module and the data processing module can quickly analyze key parameters such as the position and shape of the measured object, providing accurate data support for the control mainboard. Thus, since the signal controller 7 and signal adapter card 8 are respectively electrically connected to the control system 6, and the laser measurement component 1 is electrically connected to the signal controller 7, the control system 6 can simultaneously control the laser measurement component 1, the rotation component 2, and the positioning component 3, while also allowing communication with a computer or other external device via the signal adapter card 8 to achieve remote control, data transmission, and command issuance. In an exemplary embodiment, the signal adapter card 8 may include a GPIB-USB adapter card and an RS-485 bus signal adapter card 8. The GPIB-USB adapter card is used to communicate with a computer or other external device, and the RS-485 bus signal adapter card 8 is used to drive and connect with the positioning component 3, the rotation drive motor 24 and the fine-tuning component 43 to achieve automatic control and precise control between the positioning component 3, the rotation drive motor 24 and the fine-tuning component 43.
[0068] In some embodiments, both the outer shell 52 and the inner shell 51 are provided with a wiring tube 53, and the wiring between the control system 6 and the signal controller 7, the wiring between the control system 6 and the signal adapter card 8, and the wiring between the laser measurement component 1 and the signal controller 7 are all routed through the wiring tube 53.
[0069] In this embodiment, the wiring conduit 53 may include a transverse wiring conduit and a longitudinal wiring conduit, wherein the longitudinal wiring conduit extends along a first direction and the transverse wiring conduit extends along a second direction, with the first and second directions intersecting. Thus, since the wiring between the control system 6 and the signal controller 7, the wiring between the control system 6 and the signal adapter card 8, and the wiring between the laser measurement assembly 1 and the signal controller 7 are all routed through the wiring conduit 53, all wiring within the ablation measurement device can be routed within the wiring conduit 53. This not only facilitates wiring guidance, but also prevents short circuits caused by wiring confusion, thereby ensuring normal measurement by the ablation measurement device.
[0070] In some embodiments, the ablation measurement device further includes an illumination assembly; an illumination conduit is connected to the housing assembly 5, through which light emitted by the illumination assembly is emitted into the inner cavity of the housing assembly 5. Thus, if the illumination conditions within the inner cavity of the housing assembly 5 do not meet the requirements for laser testing, the illumination assembly can be used to assist in testing, thereby ensuring the accuracy of the ablation measurement device.
[0071] As can be seen from the above embodiment, in the embodiment of the present utility model, since the laser measurement component 1 is fixed to the rotating component 2, the rotating component 2 rotates about the first rotation axis, and the positioning component 3 includes a rotation sensor 31 and an optical displacement sensor 32, with the rotation sensor 31 mounted on the rotating component 2 and the optical displacement sensor 32 mounted on the laser measurement component 1, the laser measurement component 1 can rotate synchronously with the rotating component 2 about the first rotation axis, thereby enabling the laser measurement component 1 to rotate in different directions, thereby enabling the laser measurement component 1 to have measurement angles in different directions and at different positions. In addition, the positioning component 3 includes the rotation sensor 31 and the optical displacement sensor 32, with the rotation sensor 31 mounted on the rotating component 2 and the optical displacement sensor 32 mounted on the laser measurement component 1, thereby ensuring that the rotation of the laser measurement component 1 and the rotation of the rotating component 2 are accurately controllable. Since the supporting platform 4 is arranged on one side of the laser measurement component 1 in the first direction and is located in the irradiation direction of the laser measurement component 1, the first direction and the direction of intersection of the plane where the supporting platform 4 are located, and the first direction and the extension direction of the first rotation axis coincide with each other, the thermal insulation material arranged on the supporting platform 4 can be measured with high precision by the laser measurement component 1 and the precise control of the rotating component 2, thereby realizing the high-precision measurement requirements of the thermal insulation material. In summary, the ablation amount measuring device provided by the embodiment of the present invention can utilize the laser measurement component 1 to irradiate the surface of the thermal insulation material, and the ablation condition of the thermal insulation material can be inferred by the reflection or scattering characteristics of the measurement laser beam of the laser measurement component 1. The laser measurement component 1 can measure the thickness change of the thermal insulation material in a non-contact manner, and the laser beam of the laser measurement component 1 has extremely high accuracy, and can achieve micron-level or even nanometer-level measurement without contacting the thermal insulation material being measured, thereby avoiding damage or contamination to the thermal insulation material being measured. At the same time, the rotating component 2 can enable the laser measurement component 1 to have measurement angles in different directions and positions, that is, the measurement range of the laser measurement component 1 can be unrestricted, which can further improve the measurement accuracy of the ablation amount measuring device. Moreover, since the structure of the ablation amount measuring device provided by the embodiment of the present invention is relatively simple, the production and preparation cost of the ablation amount measuring device is reduced.
