Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0049] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to practice the invention. In other embodiments, well-known structures, circuits, materials, or methods have not been specifically described in order to avoid obscuring the invention.

Therefore, the phrases "an embodiment," "an example," "an example," or "an example" appearing in various places throughout the specification do not necessarily refer to the same embodiment or example.

Moreover, those skilled in the art will understand that the illustrations provided herein are for illustrative purposes and are not necessarily drawn to scale.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0052] like Figures 1-4 As shown, this embodiment of the invention provides a model tunnel sensor deployment and retrieval device, which includes a first fixing component 1, a second fixing component 2, a first cable fixing component 3, a second cable fixing component 4, a first guide component 5, and a second guide component 6. The first fixing component 1 is used to connect to a first end face along the length of the model tunnel 16; the second fixing component 2 is used to connect to a second end face along the length of the model tunnel 16; the first cable fixing component 3 is connected to the first fixing component 1; the second cable fixing component 4 is connected to the second fixing component 2; the first guide component 5 is connected to the first fixing component 1; and the second guide component 6 is connected to the second fixing component 2. The cable 10 of the first cable fixing component 3 passes through the first guide component 5 and the second guide component 6 in sequence and then connects to the second cable fixing component 4. Several sensor hangers 7 are detachably connected to the cable 10.

[0053] In this embodiment, both the first fixing component 1 and the second fixing component 2 can be made of thin steel plates. The shape of the first fixing component 1 is the same as the end face shape of one end of the model tunnel 16, and the shape of the second fixing component 2 is the same as the end face shape of the other end of the model tunnel 16. Thus, the installation of the first fixing component 1 and the second fixing component 2 has little impact on the installation of other components of the model tunnel 16. The plate surface of the first fixing component 1 is bonded to the end face of one end of the model tunnel 16, and the plate surface of the second fixing component 2 is bonded to the end face of one end of the model tunnel 16. Thus, it will not affect the main structure of the model tunnel 16. At the same time, after adopting the bonding method, the first fixing component 1 and the second fixing component 2 have a certain elastic sliding space relative to the tunnel, which has little impact on the mechanical properties of the model tunnel 16 itself.

[0054] In this embodiment, when the first fixing component 1 and the second fixing component 2 are configured with the aforementioned thin steel plate, the first fixing component 1 can be connected to the highest point of the arch of the first fixing component 1. That is, after the first fixing component 1 is connected to the model tunnel 16, the first cable fixing component 3 is located at the top position on the cross-section of the model tunnel 16. Correspondingly, the second fixing component 2 can also be connected to the highest point of the arch of the second fixing component 2. The position of the first guide component 5 is located in the space enclosed by the first fixing component 1, and the position of the second guide component 6 is located in the space enclosed by the second fixing component 2. In this way, after the cable 10 on the first cable fixing component 3 passes around the first guide component 5 and the second guide component 6 in sequence, the cable 10 is suspended in the tunnel. Depending on the testing requirements, after the first fixing component 1 and the second fixing component 2 are connected to the model tunnel 16, the positions of the first guide component 5 and the second guide component 6 along the length of the model tunnel 16 may or may not coincide. For example, if data needs to be collected at different heights of the model tunnel 16, the first guide component 5 is located above or below the second guide component 6 along the length of the model tunnel 16. If data needs to be collected at different positions in the lateral direction of the model tunnel 16, the first guide component 5 is located to the left or right of the second guide component 6 along the length of the model tunnel 16. If average data needs to be collected within the model tunnel 16, the positions of the first guide component 5 and the second guide component 6 coincide along the length of the model tunnel 16. Of course, the relative positions of the first guide component 5 and the second guide component 6 can be adjusted as needed.

[0055] In practical implementation, to reduce manufacturing difficulty and facilitate assembly, the first cable fixing assembly 3 may include a first stud 31 and a first locking nut 32; the first stud 31 is perpendicularly connected to the first fixing assembly 1; the first locking nut 32 mates with the first stud 31. The first stud 31 can be vertically welded to the plate surface of the first fixing assembly 1. After the first locking nut 32 mates with the first stud 31, the space between the first locking nut 32 and the first fixing assembly 1 can be used to wind the cable 10. Of course, a boss can be welded to the end of the first stud 31 away from the first fixing assembly 1 to prevent the first locking nut 32 from accidentally falling off. The second cable fixing assembly 4 can be constructed with the same structure as the first cable fixing assembly 3, that is, the second cable fixing assembly 4 may include a second stud 31 and a second locking nut 32; the second stud 31 is perpendicularly connected to the second fixing assembly 2; the second locking nut 32 mates with the second stud 31.

[0056] Since the first cable fixing component 3 and the first fixing component 1, and the second cable fixing component 4 and the second fixing component 2 do not require frequent disassembly and reassembly, and considering ease of operation, the first cable fixing component 3 and the second cable fixing component 4 can be replaced with a first winding motor and a second winding motor. Specifically, the first winding motor may include a first winding disc and a first stepper motor, with the output shaft of the first winding disc cooperating with the output shaft of the first stepper motor, and one end of the cable 10 fixedly connected to the first winding disc. The second winding motor may include a second winding disc and a second stepper motor, with the output shafts of the second winding disc and the second stepper motor cooperating, and the other end of the cable 10 fixedly connected to the second winding disc. In this way, when disassembling and assembling the sensor 15, the position of the cable 10 inside the model tunnel 16 can be changed by simultaneously controlling the rotation of the first stepper motor and the second stepper motor. During this process, the cable 10 can always be kept taut, making it more convenient to disassemble and assemble the sensor 15.

[0057] It is understandable that the fixed connections between the cable body 10 and the first winding disc and the second winding disc support are all detachable connections, which can meet the usage requirements of different model tunnels 16.

[0058] It should be noted that, due to the small cross-section and long length of the model tunnel 16, both the first and second stepper motors can be communication-enabled stepper motors, thus avoiding the hassle of laying signal cables. Both the first and second stepper motors can be controlled by the touchscreen. Based on the spacing of the sensors 15, operators can set corresponding step values ​​on the touchscreen to simultaneously notify the first and second stepper motors of the number of revolutions for each movement, thereby controlling the positional change of the cable 10 within the model tunnel 16.

[0059] In order to simplify the design and reduce the manufacturing cost, the first guide component 5 and the second guide component 6 in the embodiments of this application can both use existing devices.

[0060] For example, in some optional embodiments, the first guide component 5 can be configured as a first fixed pulley, with both ends of the first rotating shaft of the first fixed pulley connected to the first fixing component 1 via first connecting rods 11; wherein, both ends of the first rotating shaft are detachably connected to the first connecting rods 11; the first connecting rods 11 are rotatably connected to the first fixing component 1. The rotatable connection between the first connecting rods 11 and the first fixing component 1 can adjust the position of the first guide component 5. In specific operation, the first rotating shaft is detached from the first connecting rods 11 at both ends, and then the two first connecting rods 11 are rotated in opposite directions by the same angle, so that the first connecting rods 11 are relatively fixed to the first fixing component. After rotation, the distance between the two first connecting rods 11 changes. At this time, the original rotating shaft is replaced with a first rotating shaft of the corresponding length, and then the newly replaced first rotating shaft is connected to the two first connecting rods 11. At this time, the height of the first guide component 5 is changed on the transverse section of the model tunnel 16, and the cable body 10 part in the model tunnel 16 can be in an inclined state.

[0061] In some optional embodiments, the axial ends of the first fixed pulley can be coaxially connected to the first guide cone 13, the small diameter end of the first guide cone 13 being equal to the maximum diameter of the first fixed pulley, and the end face of the small diameter end fitting against the axial end face of the first fixed pulley. The first guide cone 13 is provided with a first clearance hole 131 for the first rotating shaft to pass through. The first guide cone 13 prevents the cable 10 from sliding off the first fixed pulley in an untensioned state.

[0062] In some optional embodiments, the second guide component 6 may also be configured as a second fixed pulley, with both ends of the second rotating shaft of the second fixed pulley connected to the second fixing component 2 via the second connecting rod 12; wherein, both ends of the second rotating shaft are detachably connected to the second connecting rod 12; and the second connecting rod 12 is rotatably connected to the second fixing component 2.

[0063] The second connecting rod 12 can be set up and connected in the same way as the first connecting rod 11. By adjusting the first connecting rod 11 and the second connecting rod 12 at the same time, the height of the first guide component 5 and the second guide component 6 can be adjusted simultaneously. That is, the cable 10 in the model tunnel 16 remains parallel to the length direction of the model tunnel 16, but the position of the cable 10 in the model tunnel 16 changes.

[0064] In some optional embodiments, a second guide cone 14 is coaxially connected to both ends of the second fixed pulley. The small diameter end of the second guide cone 14 is equal to the maximum diameter of the second fixed pulley, and the end face of the small diameter end is in contact with the axial end face of the second fixed pulley. A second clearance hole 141 is provided on the second guide cone 14 for the second rotating shaft to pass through. By providing the second guide cone 14, in conjunction with the first guide cone 13, it is possible to further prevent the cable 10 from sliding off the first fixed pulley and / or the second fixed pulley when it is not tensioned and loaded.

[0065] In some embodiments, both the first connecting rod 11 and the second connecting rod 12 can be configured as telescopic rods, with the first connecting rod 11 rotatably connected to the first rotating shaft and the second connecting rod 12 rotatably connected to the second rotating shaft. This eliminates the need to disassemble or replace the first or second rotating shaft when adjusting the position of the first guide assembly 5 or the second guide assembly 6, further improving operational convenience.

[0066] In some optional embodiments, the model tunnel sensor deployment and retrieval device may further include a third guide component 8 and a fourth guide component 9; the third guide component 8 is connected to the first fixing component 1; the fourth guide component 9 is connected to the second fixing component 2; the cable 10 of the first cable fixing component 3 passes through the fourth guide component 9, the third guide component 8, the first guide component 5 and the second guide component 6 in sequence and then connects to the second cable fixing component 4.

[0067] The third guide component 8 and the fourth guide component 9 are provided to allow the cable body 10 to be wound at multiple points, thus ensuring the tension of the cable body 10.

[0068] In some optional embodiments, the fourth guide component 9 is configured as a fourth fixed pulley, with both ends of the fourth rotating shaft of the fourth fixed pulley connected to the second fixing component via a fourth connecting rod; wherein, both ends of the fourth rotating shaft are detachably connected to the fourth connecting rod; and the fourth connecting rod is rotatably connected to the second fixing component. Thus, the position of the fourth fixed pulley is adjustable. After the cable 10 is tensioned, the position of the fourth fixed pulley can be adjusted to further tension the cable 10, improving the relative stability of the sensor 15 on the cable 10.

[0069] It is understood that the third guide component 8 can also be configured as a third fixed pulley, with both ends of the third rotating shaft of the third fixed pulley connected to the third fixed component via a third connecting rod; wherein, both ends of the third rotating shaft are detachably connected to the third connecting rod; and the third connecting rod is rotatably connected to the third fixed component. In this way, the positions of the third guide component 8 and the fourth guide component 9 can be adjusted synchronously, and the cable segment 10 between the third guide component 8 and the fourth guide component 9 can also be used to install the sensor 15.

[0070] In some optional embodiments, the sensor mounting component 7 is clamped and connected to the cable body 10. In specific implementations, the sensor mounting component 7 may include a clamping component and a hanging ring. The clamping component can be any existing clamp, and the hanging ring is fixedly connected to the clamp and is used to hang the sensor 15.

[0071] In use, release the first cable fixing component 3 and the second cable fixing component 4 from fixing the cable 10, and simultaneously tension the cable 10 manually. Clamp the first sensor 15 onto the cable 10 at the end of the model tunnel 16, and then pull the cable 10 at the other end of the model tunnel 16 to allow the first sensor 15 to enter the model tunnel 16. When the pulling amount reaches the preset sensor 15 spacing value, clamp the second sensor 15, and repeat the cycle. After the last sensor 15 is installed, fix the cable 10 with the first cable fixing component 3 and the second cable fixing component 4. The excess cable 10 at both ends can be stored by winding. If sensor 15 needs to be removed, contact the first cable fixing component 3 and the second cable fixing component 4 to fix the cable 10. At the same time, tension the cable 10 by manpower and pull the cable 10. When the first sensor 15 is located at the end of the model tunnel 16, remove the first sensor 15. Then continue to pull the cable 10 to remove the second sensor 15. Repeat this process until the last sensor 15 is removed. Then fix the cable 10 with the first cable fixing component 3 and the second cable fixing component 4.

[0072] If the first cable fixing component 3 and the second cable fixing component 4 are replaced by the first winding motor and the second winding motor respectively, then it is only necessary to control the start and stop of the first stepper motor and the second stepper motor simultaneously.

[0073] The method of using the model tunnel sensor deployment and retrieval device, based on any of the model tunnel sensor deployment and retrieval devices described in the above embodiments, includes the following steps:

[0074] The first fixing component 1 and the second fixing component 2 are respectively connected to the first end face and the second end face at both ends of the length direction of the model tunnel 16;

[0075] The first cable fixing component 3 and the first guide component 5 are installed on the first fixing component 1, and the second cable fixing component 4 and the second guide component 6 are installed on the second fixing component 2;

[0076] One end of the cable body 10 passes sequentially around the first guide component 5 and the second guide component 6;

[0077] Marking points are made on the cable body 10 at preset intervals. When one end of the cable body 10 is pulled, when the marked point enters the tunnel model 16, the sensor hanger 7 is detachably connected to the cable body 10 corresponding to the marked point and the sensor 15 is hung there.

[0078] When the number of sensors 15 meets the preset requirements, the two ends of the cable body 10 are connected to the first cable body fixing component 3 and the second cable body fixing component 4 respectively.

[0079] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
