[0040] See also Figure 1 The bridge inspection and collection device for unmanned aerial vehicles provided by the embodiment of the utility model includes: a support component 1, a drive component 2, an image collection component 3 and a first reflection component 4. Among them, the support component 1 is used to be fixedly connected to the bottom of the unmanned aerial vehicle; the drive component 2 is connected to the support component 1; the image collection component 3 is connected to the driving end of the drive component 2, and the drive component 2 is used to drive the image collection component 3; the first reflection component 4 includes a first connecting rod 41 and a first reflector 42, one end of the first connecting rod 41 is connected to the support component 1, and the other end is connected to the first reflector 42, the mirror surface of the first reflector 42 is set relative to the image collection component 3, and is inclined in the direction close to the image collection component 3 from top to bottom, and the first reflector 42 is used to reflect the upper light into the lens of the image collection component 3.

[0041] During the specific implementation: the support component 1 is connected to the drone, so that the bridge inspection and acquisition device is installed on the drone. The drone is operated to carry the bridge inspection and acquisition device to enter under the bridge to be inspected. Since the image acquisition component 3 is connected to the driving end of the driving component 21, the driving component 21 can be controlled to adjust the direction of the lens of the image acquisition component 3. When the lens of the image acquisition component 3 rotates in the horizontal plane to be offset from the first reflection component 4, the drone can be operated to carry the bridge inspection and acquisition device to complete the image acquisition of the side of the bridge. If the lens of the image acquisition component 3 is directed to the first reflection component 4, since the mirror surface of the first reflection component 4 is set relative to the lens of the image acquisition component 3, and its inclination direction is inclined in the direction close to the image acquisition component 3 from top to bottom, the light from above is reflected into the lens of the image acquisition component 3 through the principle of mirror reflection of light, so as to achieve a convenient safety inspection of the bottom of the bridge.

[0042] As a possible implementation, Figure 3As shown, in this embodiment, the bridge inspection and collection device further includes a second reflection component 5, the second reflection component 5 includes a second connecting rod 51 and a second reflector 52, one end of the second connecting rod 51 is fixedly connected to the support component 1, the second reflector 52 is fixedly arranged at the other end of the second connecting rod 51, the mirror surface of the reflector is arranged relative to the image collection component 3, the second reflector 52 is inclined in the direction away from the image collection component 3 from top to bottom, and the second reflector 52 is used to reflect the light below into the lens of the image collection component 3. In this way, when it is necessary to inspect the bridge deck, the unmanned aerial vehicle carrying the bridge inspection and collection device can be operated to be located above the bridge deck to be observed. Since the driving component 2 is connected to the image collection component 3, the lens of the image collection component 3 can be aimed at the second reflector 52 by controlling the driving component 2. Since the mirror surface of the second reflector 52 is facing downward, the light below is reflected by the second reflector 52 and enters the lens. In this way, the image collection component 3 obtains the scene below the unmanned aerial vehicle, and the inspection of the bridge deck is completed.

[0043] Furthermore, when collecting images of the bridge deck below the drone collection device, the mirror surface of the second reflector 52 can be set to be inclined at 45° to the horizontal plane. In this way, the scene directly below the drone collection device can be reflected into the image collection component 3, so that the positioning is accurate when operating the drone, and the drone only needs to be adjusted to be directly above the position to be observed.

[0044] It should be noted that the mirror surface of the second reflector 52 is set to be inclined at 30°, 40°, 50° or 60° to the horizontal plane. As long as the scene below can be reflected into the lens of the image acquisition component 3 through the principle of mirror reflection of light, the inclination angle of the mirror surface of the second reflector 52 is not limited.

[0045] Furthermore, the mirror surface of the first reflector 42 is set to be inclined at 30°, 40°, 50° or 60° to the horizontal plane. As long as the scene below can be reflected into the lens of the image acquisition component 3 through the principle of mirror reflection of light, the inclination angle of the mirror surface of the first reflector 42 is not limited.

[0046] Furthermore, when capturing images of the bridge deck below the drone collection device, the center of the mirror surface of the second reflector 52 is set at the horizontal extension of the lens of the image collection component 3. Such a setting can ensure that the scene directly below the bridge inspection and collection device is fully reflected into the lens of the image collection component 3, so that a clear, high-quality image can be obtained.

[0047] Furthermore, when capturing images of the bottom of the bridge located above the drone collection device, the center of the mirror surface of the first reflector 42 is set at the horizontal extension of the lens of the image collection component 3. Such a setting can ensure that the scene directly above the bridge inspection and collection device is fully reflected into the lens of the image collection component 3, so that a clear, high-quality image can be obtained.

[0048] As a possible implementation, the support assembly 1 includes a connection base 11 and a frame 12, the connection base 11 is used to be fixedly connected to the drone, the drive assembly 2 is fixed to the connection base 11, the frame 12 is arranged outside the drive assembly 2 and is fixedly connected to the connection base 11, and the first connecting rod 41 and the second connecting rod 51 are fixed to the outer wall of the frame 12. When installing the bridge inspection and collection device, the connection base 11 is connected to the drone. The purpose of such a setting is to provide a fulcrum platform for the support assembly 1. When operating the drone to realize the safety inspection of the bridge, the frame 12 can be connected to the lower end surface of the connection base 11, so that the drone can maintain its stability and is not easy to tilt.

[0049] It is worth mentioning that the structure of the frame 12 can be a frame structure or a cylindrical structure. The frame 12 is arranged outside the driving assembly 2 to support the driving assembly 2 and ensure its stability during driving. At the same time, since the frame 12 is arranged outside the driving assembly 2, it can provide necessary protection for it. While supporting the rotation of the driving assembly 2, the driving assembly 2 can rotate smoothly around its axis, ensuring that the bridge drone collection device can operate normally.

[0050] It should be noted that the connecting base 11 is used to be fixedly connected to the UAV so as to fix the bridge inspection and data collection device on the UAV. No other specific limitations are imposed on the connection method between the connecting base 11 and the UAV. It only needs to be able to fix the bridge inspection and data collection device to the UAV, so that the UAV can be controlled to carry the bridge inspection and data collection device to perform safety inspections on the bridge.

[0051] As a possible implementation, Figure 1As shown, in this embodiment, the frame 12 includes a shell 121 and a U-shaped plate 122, the shell 121 is fixedly connected to the connecting base 11, the second connecting rod 51 is fixedly connected to the shell 121, a through hole is opened at the bottom of the shell 121, the through hole is used to pass the driving end of the driving component 2, the U-shaped plate 122 is fixedly connected to the outer wall of the shell 121, the two oppositely arranged side plates of the U-shaped plate 122 are arranged parallel to the horizontal plane, and there is a accommodating space between the two side plates of the U-shaped plate 122, and the accommodating space is used to place the image acquisition component 3. In this embodiment, the U-shaped plate 122 is divided into a first plate and a second plate, one end surface of the first plate and one end surface of the second plate are fixed to a fixed plate to form a U-shaped plate 122 structure, wherein the length of the first plate of the U-shaped plate 122 extending out of the fixed plate is less than the length of the second plate extending out of the fixed plate, the other end surface of the first plate of the U-shaped plate 122 is fixedly connected to the housing 121, and the second plate of the U-shaped plate 122 is located below the first plate of the U-shaped plate 122 and is arranged parallel to the first plate of the U-shaped plate 122. In this way, the through hole opened at the bottom of the housing 121 is used to pass the driving component 2, and the image acquisition component 3 is positioned on the second plate of the U-shaped plate 122 at a position opposite to the through hole through the driving component 2. Due to the structure of the U-shaped plate 122, a space is left inside the U-shaped plate 122 close to the fixed plate, providing sufficient space for the horizontal rotation of the image acquisition component 3. In addition, due to the structure that one end of the U-shaped plate 122 is open and the two sides are transparent, the light can enter the lens of the image acquisition component 3 after being reflected by the mirror. In this way, the image acquisition component 3 is placed on the second plate of the U-shaped plate 122 , so that the image acquisition component 3 is sufficiently supported and is conducive to the horizontal rotation of the image acquisition component 3 .

[0052] As a possible implementation, in this embodiment, a groove is provided on the upper surface of the plate below the U-shaped plate 122 in the accommodation space, and the bottom of the image acquisition component 3 has a protruding structure 7 that matches the groove, and the groove is used to limit and fix the image acquisition component 3. In this way, when the driving component 2 drives the image acquisition component 3 to rotate, when it rotates to a position where the lens of the image acquisition component 3 is aligned with the mirror surface of the first reflector 42 or the second reflector 52, the rotation is stopped so that the protruding structure 7 at the bottom of the image acquisition component 3 is embedded in the groove matched with the structure, thereby fixing the angle of the lens of the image acquisition component 3 in the horizontal plane, ensuring the stable alignment of the lens and the reflector, or ensuring the stable alignment of the lens and the side of the bridge.

[0053] It should be noted that the groove is used to limit and fix the image acquisition component 3. The shape of the groove determines the shape of the protruding structure 7 at the bottom of the image acquisition component 3 that needs to be matched therewith, and further determines the lens alignment direction when the image acquisition component 3 is fixed. Since it is necessary to reflect the light at the bottom or top of the bridge into the lens of the image acquisition device through mirror reflection, so as to achieve observation of the bottom or top of the bridge, the shape of the groove further determines the setting position of the first reflector 42 or the second reflector 52, that is, the mirror surface of the first reflector 42 or the second reflector 52 needs to be aligned with the lens alignment direction when the image acquisition component 3 is fixed by the groove. Therefore, the shape of the groove can be various, and different groove shapes determine different setting positions of the reflector component.

[0054] As a possible implementation, Figure 5 As shown, in this embodiment, the groove is a cross groove 6. At this time, the bottom protrusion structure 7 of the image acquisition component 3 matched with the cross groove 6 is a long strip protrusion, and the long strip protrusion can contact and cooperate with each of the two grooves of the cross groove 6 to achieve the fixation of the image acquisition component 3. Such a setting determines that the angle of the lens of the image acquisition component 3 after rotation in the horizontal plane is 0°, 90° and 180°, which respectively match the three directions of the cross groove 6. At the same time, the direction in which the lens of the image acquisition component 3 is aligned and the mirror alignment direction of the first reflector 42 or the second reflector 52 are on the same straight line, so that the light can enter the lens of the image acquisition component 3 through mirror reflection to observe the bottom or the bridge surface, or, when the lens of the image acquisition component 3 is offset from the first reflector 42 or the second reflector 52, the side of the bridge can also be observed.

[0055] As a possible implementation, in this embodiment, the first connecting rod 41 and the second connecting rod 51 are arranged at different side positions on the outer side wall of the support assembly 1. Specifically, the angle is evenly divided into four parts around the support assembly 1 in a horizontal plane, and each part is regarded as a same side position. The angle between the first connecting rod 41 and the second connecting rod 51 projected on the same horizontal plane is greater than 90°. As an optimization, the angle can be 90°, 135°, 180°, etc. The purpose of such arrangement is that since the reflective assembly connected to the outer side wall of the support assembly 1 has its own weight, when operating the drone to use the bridge inspection collection device to perform a bridge safety inspection, if the setting position of the reflective assembly is located on the same side of the support assembly 1, it will cause uneven force on the drone, so that the drone has a force to deflect to the side with excessive weight, which hinders the realization of its function. Therefore, in this embodiment, the positions where the first connecting rod 41 and the second connecting rod 51 are connected on the support assembly 1 are located at different side positions on the outer side wall of the support assembly 1.

[0056] Furthermore, if Figure 3 As shown, in this embodiment, the other end of the first connecting rod 41 is fixedly connected to the bottom surface of the U-shaped plate 122. Specifically, one end of the first connecting rod 41 is vertically arranged at the bottom of the U-shaped plate 122, and the first connecting rod 41 has two bends in sequence. At the first bend, the first connecting rod 41 perpendicular to the bottom of the U-shaped plate 122 is bent to be parallel to the horizontal plane, and at the second bend, the first connecting rod 41 is bent upward along the perpendicular to the horizontal plane, and the other end of the first connecting rod 41 is connected to the first reflector 42. The working principle is: when conducting a safety inspection of the bottom of the bridge, the drone carrying the bridge inspection and collection device is operated to enter the bottom of the bridge. At this time, the first reflector 42 reflects the scene of the bottom of the bridge into the lens of the image acquisition component 3 through the inclined mirror surface of the first reflector 42, and the image of the bottom of the bridge can be surveyed. The purpose of such arrangement is to lead the first connecting rod 41 out from the bottom of the U-shaped plate 122, and the first reflector 42 is arranged to be inclined from top to bottom toward the image acquisition component 3, which will not cause obstruction of the light path, so that the bottom of the bridge located above the drone acquisition device can be clearly and completely observed.

[0057] It should be noted that, when considering the setting position of the first connecting rod 41 and the second connecting rod 51 on the support assembly 1, it is necessary to consider whether the first connecting rod 41 or the second connecting rod 51 blocks the light path, that is, the spatial position of the first connecting rod 41 connected to the first reflector 42 with a mirror surface tilted upward cannot be above the mirror surface, which will cause the light path above the first reflector 42 to be blocked, thereby preventing a comprehensive observation of the scene above. Similarly, the spatial position of the second connecting rod 51 connected to the second reflector 52 with a mirror surface tilted downward cannot be below the mirror surface, which will also cause the light path below the second reflector 52 to be blocked, thereby preventing a comprehensive observation of the scene below.

[0058] As a possible implementation, Figure 1As shown, in this embodiment, the driving component 2 includes a driving part 21 and a rotating rod 22. The driving component 21 is fixedly arranged on the supporting component 1. The driving component 21 includes a driving displacement component and a driving rotation component. One end of the rotating rod 22 is connected to the driving component 2, and the other end is fixedly connected to the image acquisition component 3. The driving rotation component is used to drive the rotating rod 22 to rotate around the axis, and the driving displacement component is used to drive the rotating rod 22 to move up and down. Specifically, the driving component 21 includes a driving displacement component and a driving rotation component. The driving displacement component is fixedly connected to the connecting base 11, and the driving end of the driving displacement component is fixedly connected to the driving rotation component. The rotating rod 22 is connected below the driving rotation component. During specific implementation, the driving displacement component fixedly connected to the connecting base 11 controls the driving end to pull the driving rotating component and the rotating rod 22 upward, so that the raised structure 7 at the bottom of the image acquisition component 3 connected below the rotating rod 22 is disengaged from the cross groove 6 upward, and then the driving rotating component drives the rotating rod 22 to drive the lens of the image acquisition component 3 to rotate to the desired position, and then the driving end of the driving displacement component drives the driving rotating component to move downward, so that the raised structure 7 at the bottom of the image acquisition component 3 is stuck in the cross groove 6 to complete the fixation.

[0059] As a possible implementation, the direction of the mirror surface of the first reflector 42 and the second reflector 52 is staggered with the sealing end of the U-shaped plate 122. That is, the direction of the mirror surface of the first reflector 42 and the second reflector 52 cannot be set in the opposite direction of the opening direction of the U-shaped plate 122. If the direction of the mirror surface of the first reflector 42 or the second reflector 52 is set toward the sealing end of the U-shaped plate 122, when the image acquisition component 3 rotates on the horizontal plane in the U-shaped plate 122, the reflection of the bottom surface or the top surface of the bridge by the first reflector 42 or the second reflector 52 cannot be captured by the lens of the image acquisition component 3. When the direction of the mirror surface of the first reflector 42 and the second reflector 52 is staggered with the sealing end of the U-shaped plate 122, it is only necessary to adjust the rotation of the image acquisition component 3 to align the lens of the image acquisition component 3 with the mirror surface of the first reflector 42 or the second reflector 52, thereby realizing the observation of the bottom surface or the top surface of the bridge by the principle of mirror reflection of light.

[0060] It is worth mentioning that the image acquisition component 3 is a high-definition acquisition camera. The image acquisition component 3 is a key component for acquiring bridge images. This embodiment uses a high-definition acquisition camera to ensure that clear and high-quality images are obtained.

[0061] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
