Description

Technical Field

[0001] The present invention belongs to the technical field of pressure scanners, and more specifically, particularly relates to a pressure scanner for aerospace test environments. Background Art

[0002] In aerospace tests, the technical background of pressure scanners for aerospace experiments is closely linked to the development of aerospace engineering. Their research and development and applications stem from the special requirements of aerospace experiments for pressure measurement, as well as the need to address numerous challenges faced by traditional pressure measurement technologies in the aerospace field.

[0003] Currently, the following technical problems at least exist in pressure scanners:

[0004] First, in wind tunnel tests, in order to study the aerodynamic characteristics of a model in different postures, it is necessary to frequently adjust the posture of the model. The change in the posture of the model may cause the positions of the pressure measurement points installed on the model to change, thereby causing the pipelines connected to these measurement points to be pulled or squeezed, resulting in the pipelines being bent or falling off, which affects the accuracy of experimental measurements.

[0005] Second, there are numerous devices at the aerospace experiment site, with a compact layout and intense experimental tasks. The pressure scanner needs to be frequently installed, disassembled, and maintained to adapt to different experimental scenarios and equipment combinations. Traditional installation methods are complex, time-consuming, and difficult to maintain, making it difficult to meet the requirements of efficient operation of aerospace experiments. There is an urgent need for a pressure scanner that can be installed quickly and conveniently. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a pressure scanner for aerospace test environments to solve the above problems.

[0007] A pressure scanner for aerospace test environments includes a scanner main body. A pressure measurement channel for connecting a pressure transmission pipeline is installed at the front end of the scanner main body. An installation base is provided below the scanner main body. Two groups of fixing mechanisms are provided between the scanner main body and the installation base. The fixing mechanism includes a locking foot shell and a locking switch shell. A first fixing pin is provided inside the locking foot shell, and a second fixing pin is provided inside the locking switch shell. The first fixing pin and the second fixing pin are clamped. A flipping mechanism is provided above the installation base. The flipping mechanism is used to automatically protect the scanner main body when the protective shell is installed and can also assist in the disassembly of the fixing mechanism. A protective shell is provided on the scanner main body. A pipeline support mechanism is installed at the upper end of the protective shell. An arc-shaped fixing pipe for fixing the pressure transmission pipeline is provided at the front end of the protective shell. An anti-slip pad is provided on the inner wall of the arc-shaped fixing pipe for fixing the pressure transmission pipeline connected to the pressure measurement channel.

[0008] Preferably, two L-shaped grooves are formed in the mounting base, and both of the fixing mechanisms are arranged in the L-shaped grooves formed in the mounting base. A torsion spring shaft and a limiting post for limiting are fixedly installed inside the locking switch housing.

[0009] Preferably, the flipping mechanism includes a first fixing plate, a rack is fixedly installed on the first fixing plate, a first gear is meshed with the lower end of the rack, a first gear shaft is rotatably installed through the first gear, a second fixing plate is fixedly installed at the lower end of the scanner body, and the first gear shaft is fixedly connected with the second fixing plate. A first gear belt is meshed with the circumferential surface of the first gear, a second gear is meshed with the inner wall of the first gear belt, a second gear shaft is rotatably installed through the second gear, a third fixing plate is fixedly installed at the lower end of the scanner body, and the second gear shaft is fixedly installed on the third fixing plate. A second gear belt is meshed with the circumferential surface of the second gear, a ratchet gear is meshed with the inner side wall of the second gear belt, a rotating shaft is fixedly installed through the ratchet gear, fixing blocks are fixedly installed on both the left and right sides of the rotating shaft, and the fixing blocks are fixed to the scanner body.

[0010] Preferably, the pipeline support mechanism includes a chute panel, the chute panel is installed in the installation groove provided at the upper end of the protective housing. Two V-shaped chutes are formed in the chute panel. Two sliding blocks for fixing and sliding are arranged in each V-shaped chute. Magnets are arranged on the opposite surfaces of each group of sliding blocks. A connecting plate is fixedly installed on each group of sliding blocks. A fixing rod is fixedly installed through every two connecting plates. The fixing rod is fixedly installed with a clamping plate. The clamping plate and the arc-shaped fixing pipe are fixedly installed. A guiding column is slidably installed through the upper end of each clamping plate. Two groups of telescopic rods are arranged on both sides of the guiding column. Two groups of L-shaped pressing plates are fixedly installed at the rear end of the protective housing. A roller is arranged at the bottom of the L-shaped pressing plate. A workbench is fixedly installed at the bottom of the mounting base through bolts. Two L-shaped supporting feet for limiting the scanner body are fixedly installed at the lower end of the scanner body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, a pipeline support mechanism including a slide groove panel, a V-shaped slide groove, a slider, a connecting plate, a fixing rod, a clamping plate, an arc-shaped fixing tube, a guide column, a telescopic rod and other components is arranged at the upper end of the protective shell. When the pressure transmission pipeline of the pressure measuring channel is connected, the front end of the protective shell is pulled open, and the components immediately work together. The clamping plate drives the guide column and the telescopic rod to extend, and the slider slides in the V-shaped slide groove, causing the two groups of clamping plates to move relative to each other. When reaching the lower end, the built-in magnets of the slider are adsorbed and fixed to each other. Each arc-shaped fixing tube is slightly bent downward and has a built-in anti-slip pad, which fixes the pressure transmission pipeline in the arc-shaped fixing tube, effectively preventing the pipeline from bending and falling off. This structure creates a stable measurement environment for the pressure sensor built into the pressure measuring channel, ensures that the pressure measurement data is accurate and correct, and provides a reliable data basis for aerospace testing.

[0013] In the present invention, a flipping mechanism consisting of a first fixed plate, a rack, a first gear, a first gear transmission belt, a second gear, a second gear transmission belt, a ratchet gear, etc. is arranged above the mounting base. During the installation of the scanner body, the first gear is meshed with the rack to start a series of precise transmission processes. As the transmission continues, the protective shell automatically rotates and presses down to cover the scanner body to complete the automated protection. To release the protection, it is only necessary to lift the external handle of the protective shell, and the ratchet gear triggers the built-in spring of the ratchet to avoid driving other components, thereby ensuring that the protection action is efficient and smooth and will not interfere with other parts of the equipment. This greatly enhances the protection performance and operational safety of the equipment, allowing the equipment to operate stably in a complex aerospace test environment.

[0014] In the present invention, a fixing mechanism including a series of components such as a locking foot housing, a first fixing pin, a locking switch housing, a torsion spring shaft, and a second fixing pin is arranged in the L-shaped groove of the mounting base. When the scanner body is installed, the L-shaped supporting foot slides smoothly along the L-shaped groove. When the locking foot housing contacts the locking switch housing, the torsion spring on the torsion spring shaft exerts force instantly, pushing the second fixing pin to quickly engage with the first fixing pin, thereby achieving fast and stable installation. This design greatly improves the installation efficiency.

[0015] In the present invention, two groups of L-shaped pressure plates with rollers on the bottom are fixedly installed at the rear end of the protective shell. When the protective shell is closed, the L-shaped pressure plates assist in fixing the protective shell to enhance the protection stability. When the protective shell is opened after the experiment, the rollers are flipped down with the L-shaped pressure plates, triggering the fixing mechanism to unlock, making it convenient for the staff to quickly remove the scanner from the mounting base, thereby improving the convenience of equipment use, optimizing the operating experience, and improving the efficiency of aerospace testing.

Detailed implementation manners

[0028] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] Please refer toFigure 1 - Figure 11 , the present invention provides a pressure scanner for aerospace test environment, which includes an installation base 12. L-shaped grooves 16 are opened at both the left and right ends of the installation base 12, and a workbench 13 is fixedly installed at the bottom of the installation base 12 through bolts.

[0030] Above the installation base 12, there is a scanner main body 14. A pressure measurement channel 18 for connecting a pressure transmission pipeline is installed at the front end of the scanner main body 14. Two L-shaped support feet 19 for limiting the scanner main body 14 are fixedly installed at the lower end of the scanner main body 14. The L-shaped support feet 19 are slidably installed inside the L-shaped grooves 16 opened in the installation base 12 and are adapted to each other.

[0031] A protective housing 11 for protection is arranged outside the scanner main body 14. The material of the protective housing 11 is a shielding material, which can prevent the scanner main body 14 from being interfered by external electromagnetic fields.

[0032] Fixing mechanisms are arranged inside the L-shaped grooves 16 opened in the installation base 12. Both groups of fixing mechanisms are used for the fixing and installation of the scanner main body 14, and at the same time, the quick disassembly of the scanner main body 14 on the installation base 12 can be completed. A flipping mechanism is arranged above the installation base 12. The flipping mechanism is used for automatically protecting the scanner main body 14 when the protective housing 11 is installed, and at the same time, it can assist in the disassembly of the fixing mechanism. A pipeline support mechanism is installed at the upper end of the protective housing 11, which is used for the fixing of the pressure transmission pipeline connecting the pressure measurement channel 18 and for preventing inaccurate measurement caused by the bending of the pipeline.

[0033] In this embodiment, as Figure 1 , Figure 2 , and Figure 9As shown in the figure, the fixing mechanism includes a locking support leg housing 42. The adjacent ends of the locking support leg housing 42 and the locking switch housing 43 are both designed to be open. A first fixing pin 44 for locking is fixedly installed inside the locking support leg housing 42. Two L-shaped grooves 16 opened in the mounting base 12 are both fixedly installed with locking switch housings 43. A second fixing pin 47 is arranged inside the locking switch housing 43. The first fixing pin 44 can be locked with the second fixing pin 47. A torsion spring shaft 46 and a limiting post 45 for limiting are fixedly installed inside the locking switch housing 43. The torsion spring shaft 46 is connected to the second fixing pin 47 through a torsion spring. A switch plate is installed at the side end of the second fixing pin 47. The second fixing pin 47 is kept at a fixed angle by the torsion spring arranged on the torsion spring shaft 46 and the limiting of the limiting post 45. When installing the scanner, the L-shaped support leg 19 and the locking support leg housing 42 can slide in the L-shaped groove 16 opened in the mounting base 12. During the process of the locking support leg housing 42 contacting the locking switch housing 43, the front end of the second fixing pin 47 inside the locking switch housing 43 moves along the inclined surface of the rear end of the first fixing pin 44. Through the action of the torsion spring on the torsion spring shaft 46, the front end of the second fixing pin 47 can be clamped with the rear end of the first fixing pin 44, completing the rapid installation of the scanner during the test process.

[0034] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown in the figure, the flipping mechanism includes a first fixing plate 21, a rack 22 is fixedly installed on the first fixing plate 21, a first gear 25 is meshed with the lower end of the rack 22, a first gear shaft 24 is rotatably installed through the first gear 25, a second fixing plate 23 is fixedly installed at the lower end of the scanner body 14, the first gear shaft 24 is fixedly connected with the second fixing plate 23, a first gear transmission belt 26 is meshed with the circumferential surface of the first gear 25, a second gear 29 is meshed with the inner wall of the first gear transmission belt 26, a second gear shaft 28 is rotatably installed through the second gear 29, a third fixing plate 27 is fixedly installed at the lower end of the scanner body 14, the second gear shaft 28 is fixedly installed on the third fixing plate 27, a second gear transmission belt 32 is meshed with the circumferential surface of the second gear 29, a ratchet gear 31 is meshed with the inner side wall of the second gear transmission belt 32, the ratchet gear 31 is fixedly installed through the rotating shaft 33, fixing blocks 34 are fixedly installed on both the left and right sides of the rotating shaft 33, a ratchet mechanism is arranged inside the ratchet gear 31 (the ratchet mechanism is a prior art, and its working principle is that when the driving gear rotates, it drives the shaft connected thereto to rotate through gear meshing, and the ratchet installed on the shaft can only rotate in one direction under the action of the ratchet pawl), the fixing blocks 34 are fixed to the scanner body 14. When installing the scanner, the first gear 25 at the lower end of the scanner body 14 will first disengage from the rack 22 and mesh with it. Under the action of the tooth grooves of the rack 22, the first gear 25 will rotate counterclockwise around the center of the first gear shaft 24, driving the first gear transmission belt 26 to drive. Through the meshing between the first gear transmission belt 26 and the first gear 25 and the second gear 29, the second gear 29 on the inner side wall of the first gear transmission belt 26 starts to rotate, further driving the second gear transmission belt 32 meshed with the circumferential surface of the second gear 29 to rotate, driving the ratchet gear 31 to rotate clockwise. When the ratchet gear 31 rotates clockwise, it drives the rotating shaft 33 and the protective housing 11 to rotate around the center of the rotating shaft 33. Through the fixing blocks 34 fixed to the scanner body 14, the protective housing 11 rotates clockwise and presses down around the center of the rotating shaft 33 to protect the scanner body 14. When the experiment needs to be completed and the protection needs to be removed, the staff can directly lift the handle outside the protective housing 11, driving the rotating shaft 33 to rotate counterclockwise. When the rotating shaft 33 rotates counterclockwise, the ratchet gear 31 triggers the spring inside the ratchet, making the ratchet gear 31 unable to drive the second gear transmission belt 32 to drive, and not affecting other components.

[0035] In this embodiment, as Figure 1 、 Figure 7 、 Figure 8 、 Figure 10As shown in the figure and the protective housing 11, the pipeline support mechanism includes a chute panel 65. Each group of chute panels 65 is installed in the installation groove provided at the upper end of the protective housing 11. Each group of chute panels 65 is provided with two V-shaped chutes 66. Each V-shaped chute 66 is internally provided with two sliders 71 for fixing and sliding. Magnets are provided on the opposite surfaces of each group of sliders 71. Each group of sliders 71 is fixedly installed with a connecting plate 69. Each two connecting plates 69 are fixedly installed through a fixing rod 72. A clamping plate 61 is fixedly installed on each group of fixing rods 72. An arc-shaped fixing plate 62 is installed on the clamping plate 61. The arc-shaped fixing tubes 62 are all slightly bent downward. An anti-slip pad is provided inside each arc-shaped fixing tube 62. A guide post 63 is slidably installed through the upper end of each clamping plate 61. Two groups of telescopic rods 64 are provided on both sides of the guide post 63. When the scanner is installed and the pressure measurement channels 18 are all connected to the pressure transmission pipelines, the experimenter pulls the front end of the protective housing 11 outward. The clamping plate 61 drives the guide post 63 and the telescopic rods 64 to extend outward. At the same time, each group of sliders 71 moves along the V-shaped chute 66 provided on the chute panel 65. The two groups of fixing rods 72 move relatively at this time and drive the two groups of clamping plates 61 to move relatively. When the sliders 71 reach the bottom of the V-shaped chute 66, they are adsorbed and fixed to each other under the action of the magnets built in the sliders 71. The arc-shaped fixing tubes 62 on the two groups of clamping plates 61 are relatively fitted. While driving each group of clamping plates 61 to pull outward, they slide inward along the guide post 63. Then, the pressure pipelines connected to the pressure measurement channels 18 are straightened and clamped in the groove between the two groups of arc-shaped fixing tubes 62. Since each arc-shaped fixing tube 62 is slightly bent downward and is internally provided with an anti-slip pad, it can effectively prevent the pressure transmission pipeline from falling off or being bent when perpendicular to the ground, providing a better measurement environment for the pressure sensors built in the pressure measurement channels 18 and preventing the problem of the laboratory pressure transmission pipeline falling off.

[0036] In this embodiment, as Figure 2 、 Figure 6 and Figure 9 shown, two groups of L-shaped pressing plates 49 are fixedly installed at the rear end of the protective housing 11. Rollers are provided at the bottom of the L-shaped pressing plates 49. When the experiment is completed and the staff turns the protective housing 11 upward, the two L-shaped pressing plates 49 will flip along with the movement of the protective housing 11. The rollers at the bottom of the L-shaped pressing plates 49 press downward, driving the switch plates at the side ends of the two second fixing pins 47 to move downward. At the same time, the heads of the second fixing pins 47 are lifted accordingly, releasing the interlock with the first fixing pin 44. At this time, the locking of the locking mechanism is released, and the staff can easily disassemble the scanner from the installation base 12.

[0037] Working principle:

[0038] First step, fix the mounting base 12 to the workbench 13 with bolts, and check the L-shaped groove 16 and the components of the fixing mechanism. Prepare the scanner main body 14, and check the pressure measurement channel 18 and the L-shaped support feet 19; prepare the protective housing 11, and check the material and the pipe support mechanism.

[0039] Second step, slide the L-shaped support feet 19 of the scanner main body 14 into the L-shaped groove 16 of the mounting base 12, lock the support foot housing 42 to contact the locking switch housing 43, and the second fixing pin 47 is clamped to the first fixing pin 44 to complete the fixation.

[0040] Third step, when installing the main body, the first gear 25 meshes with the rack 22 and rotates, driving the transmission belt and the ratchet gear 31 to rotate, so that the protective housing 11 presses down to automatically protect the main body.

[0041] Fourth step, after the installation is completed, pull the front end of the protective housing 11, the slider 71 moves along the V-shaped chute 66, and the two groups of clamping plates 61 move relative to each other. Place the pressure pipeline on the arc-shaped fixing pipe 62, and the clamping plate 61 slides to smooth the pipeline.

[0042] Fifth step, start the pressure scanner, and collect and process the pressure data through the pressure measurement channel 18.

[0043] Sixth step, after the experiment is completed, open the protective housing 11, the L-shaped pressing plate 49 presses down the switch plate to release the lock, and remove the main body for storage and maintenance.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
