Description

Technical Field

[0001] The present invention relates to the technical field of engineering surveying and mapping, and particularly to a new type of unmanned aerial vehicle (UAV)-borne engineering surveying and mapping imaging device. Background Technique

[0002] A UAV-borne engineering surveying and mapping imaging device refers to an imaging device mounted on a UAV platform for use in the field of engineering surveying and mapping. Through the flight and hovering functions of the UAV platform, these devices can conduct surveying and mapping work at low altitude or high altitude, obtain high-resolution image data, and thus provide accurate and reliable data support for engineering surveying and mapping.

[0003] After retrieval, a Chinese patent with the publication number CN218086064U discloses an aerial photography device for surveying and mapping.

Although it has the advantages of facilitating users to take pictures with different functions according to needs, reducing the limitations of the device, and improving the practicality of the device, there are still the following problems:

[0004] 1. When the thermal imaging camera is in use, it cannot rotate independently, so that it can image and irradiate different ranges and positions, reducing the imaging range;

[0005] 2. The pitch of the thermal imaging camera cannot be adjusted independently, increasing the limitations of the UAV in the range of shooting and surveying and mapping imaging;

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The serial numbers assigned to components in this document itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "coupling" as used in this invention, unless otherwise specifically stated, both include direct and indirect connection (coupling). In the description of this invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention.

[0036] In this invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0037] Refer to Figures 1-7 , a new type of unmanned aerial vehicle (UAV) - borne engineering surveying and mapping imaging device, which includes a UAV body 1. A support leg 4 is fixedly connected to the bottom of the UAV body 1. There are two support legs 4. A connecting column 2 is fixedly connected to the bottom of the UAV body 1. One end of the connecting column 2 is fixedly connected to a bottom plate 3. An elevation mechanism 6 and a rotation mechanism 5 are arranged on the top of the bottom plate 3. Both the elevation mechanism 6 and the rotation mechanism 5 are arranged between the bottom plate 3 and the UAV body 1.

[0038] Specifically, the UAV body 1 can play a role in installing and fixing the bottom plate 3 through the connecting column 2. The support legs 4 connected to the bottom of the UAV body 1 can make the UAV body 1 stable enough when landing on the ground, and reduce the possibility of damage to the bottom plate 3 due to long - term collision with the ground. The elevation mechanism 6 and the rotation mechanism 5 can cooperate with each other to achieve multi - angle thermal imaging surveying and mapping.

[0039] Further, the rotation mechanism 5 includes a mounting rod 501. The bottom of the mounting rod 501 is fixedly connected to the top of the bottom plate 3. One end of the mounting rod 501 is fixedly connected to a connecting collar 502. A fixing column 503 is fixedly connected to the inner cavity of the connecting collar 502. A servo motor 504 is fixedly connected to the top of the bottom plate 3. The output end of the servo motor 504 is fixedly connected to a rotating rod 505. The surface of the rotating rod 505 is rotatably connected to the inner cavity of the fixing column 503. One end of the rotating rod 505 is fixedly connected to a connecting ring block 506. A connecting rod 507 is rotatably connected to the inner cavity of the connecting ring block 506. One end of the connecting rod 507 is fixedly connected to a mounting block 508. A mounting base 509 is fixedly connected to the top of the mounting block 508. A thermal imaging camera body 510 is fixedly connected to the top of the mounting base 509.

[0040] Specifically, the mounting rod 501 can play a role in installing and connecting the fixing column 503 through the connecting collar 502. At the same time, when the servo motor 504 operates, it can smoothly drive the rotating rod 505 to rotate inside the fixing column 503. Since the rotating rod 505 is fixedly connected to the connecting ring block 506 and the connecting rod 507 is rotatably connected inside the connecting ring block 506, the servo motor 504 can smoothly drive the connecting rod 507 to rotate through its own operation. While the connecting rod 507 rotates, it can utilize the connection between the mounting block 508 and the mounting base 509 to smoothly drive the thermal imaging camera body 510 on the top of the mounting base 509 to rotate, thereby realizing the adjustment of the angle of the thermal imaging camera body 510. At the same time, the thermal imaging camera body 510 can perform thermal imaging mapping and imaging during operation.

[0041] Further, the pitching mechanism 6 includes a cylinder 601. The bottom of the cylinder 601 is fixedly connected to the top of the bottom plate 3. The output end of the cylinder 601 is fixedly connected to a hollow ring sleeve 602. A fixing ring block 603 is fixedly connected to the surface of the connecting rod 507. A fixing rod 604 is fixedly connected to the surface of the fixing ring block 603. One end of the fixing rod 604 is fixedly connected to a sliding sphere 605. The surface of the sliding sphere 605 is slidably connected to the inner cavity of the hollow ring sleeve 602.

[0042] Specifically, the cylinder 601 can install and fix the hollow ring sleeve 602. At the same time, the connecting rod 507 can connect the fixed rod 604 through the fixed ring block 603, and the fixed rod 604 is mainly used to connect and fix the sliding sphere 605. The surface of the sliding sphere 605 is slidably connected to the inner cavity of the hollow ring sleeve 602. When the hollow ring sleeve 602 moves up and down due to the operation of the cylinder 601, it can smoothly drive the fixed ring block 603 and the connecting rod 507 to rotate inside the connecting ring block 506 through the sliding sphere 605, thereby driving the mounting block 508 and the thermal imaging camera body 510 to perform pitching rotation. While realizing the horizontal rotation of the thermal imaging camera body 510, its pitching adjustment is carried out, increasing the range that the thermal imaging camera body 510 can survey and image during use. At the same time, the cylinder 601, the thermal imaging camera body 510, and the servo motor 504 are all electrically connected to the UAV body 1. The staff can control the operations of the cylinder 601, the thermal imaging camera body 510, and the servo motor 504 through the UAV body 1. The cylinder 601, the thermal imaging camera body 510, and the servo motor 504 are all prior arts in this field and will not be elaborated here.

[0043] Further, a hollow groove 16 is formed on the surface of the fixed column 503, and a reinforcing sleeve ring 17 is fixedly connected to the inner cavity of the connecting sleeve ring 502. The surface of the reinforcing sleeve ring 17 is fixedly connected to the inner cavity of the hollow groove 16.

[0044] Specifically, the fixed column 503 can install and fix the reinforcing sleeve ring 17 through the hollow groove 16, and through the connection between the reinforcing sleeve ring 17 and the hollow groove 16, the firmness of the connection between the connecting sleeve ring 502 and the fixed column 503 is increased, so that the fixed column 503 and the connecting sleeve ring 502 can be sufficiently stable during use and are not prone to shaking, slipping, etc. during use.

[0045] Further, a connecting block 13 is fixedly connected to the bottom of the mounting block 508. Threaded holes 14 are formed on one side of both the connecting block 13 and the mounting base 509, and a reinforcing bolt 15 is threadedly connected to the inner cavity of the threaded hole 14.

[0046] Specifically, the formation of the threaded holes 14 enables the reinforcing bolts 15 to be smoothly connected to the inside of the connecting block 13 and the mounting base 509, and the setting of the reinforcing bolts 15 can increase the stability of the connection between the mounting block 508 and the mounting base 509, thereby increasing the stability of the mounting block 508 when driving the mounting base 509 to rotate and pitch.

[0047] Further, a spring 10 is fixedly connected to the top of the mounting base 509. One end of the spring 10 is fixedly connected to a reinforcing pressure plate 11, and a rubber layer 18 is adhesively bonded to the bottom of the bottom plate 3.

[0048] Specifically, the mounting base 509 can mount and fix the reinforcement pressing plate 11 through the spring 10, and the reinforcement pressing plate 11 can further press the thermal imaging camera body 510 through the elasticity of the spring 10, thereby improving the stability of the thermal imaging camera body 510 when adjusting the angle following the mounting base 509. The rubber layer 18 can reduce the collision between the bottom plate 3 and the ground when the UAV body 1 lands on the ground, which can not only play a certain buffering role but also reduce the wear generated when the bottom plate 3 contacts the ground.

[0049] Furthermore, a reinforcement inclined block 9 is fixedly connected to one side of the mounting block 508, and one side of the reinforcement inclined block 9 is fixedly connected to the mounting base 509.

[0050] Specifically, the reinforcement inclined block 9 can further increase the connection stability between the mounting block 508 and the mounting base 509 through its connection with the mounting block 508 and the mounting base 509, thereby reducing the possibility that the mounting base 509 shakes during angle adjustment due to the unstable connection between the mounting block 508 and the mounting base 509.

[0051] Furthermore, a limiting block 8 is fixedly connected to the surface of the hollow ring sleeve 602. The inner cavity of the limiting block 8 is slidably connected to the surface of the connecting column 2. A reinforcement ring block 12 is fixedly connected to the bottom of the UAV body 1. The inner cavity of the reinforcement ring block 12 is fixedly connected to the surface of the connecting column 2. A telescopic rod 7 is fixedly connected to the top of the bottom plate 3, and one end of the telescopic rod 7 is fixedly connected to the bottom of the hollow ring sleeve 602.

[0052] Specifically, the limiting block 8 can play a certain limiting role in the up and down movement of the hollow ring sleeve 602 through the connecting column 2, thereby improving the stability of the hollow ring sleeve 602 during movement. The telescopic rod 7 can also play a limiting and auxiliary role in the hollow ring sleeve 602 through its own telescopic action, further increasing the stability of the hollow ring sleeve 602 during up and down movement. And the reinforcement ring block 12 can increase the firmness of the connection between the UAV body 1 and the connecting column 2, making the connecting column 2 and the bottom plate 3 not easily shake, break, or fall off due to the blowing of the wind when following the UAV body 1 during use.

[0053] The present invention is used in the following steps:

[0054] S1: The staff can connect the thermal imaging camera body 510 to the mounting base 509 through tools and connect it to the top of the mounting base 509. Then, start the UAV body 1 to make the UAV body 1 fly in the air. During the flight of the UAV body 1, use the imaging camera of the UAV body 1 itself and the thermal imaging camera body 510 to image the engineering area that needs to be surveyed and imaged.

[0055] S2: Control the servo motor 504 to operate. Through the operation of the servo motor 504, smoothly drive the rotating rod 505 to rotate. Utilize the connection between the rotating rod 505 and the connecting ring block 506, so that the connecting ring block 506 drives the mounting block 508, the mounting base 509, and the thermal imaging camera body 510 on the top of the mounting base 509 to rotate through the connecting rod 507, realizing the adjustment of the horizontal angle during the surveying and imaging of the thermal imaging camera body 510.

[0056] S3: Control the cylinder 601 to operate, so that the cylinder 601 drives the hollow ring sleeve 602 to move up and down through the output end. When the hollow ring sleeve 602 moves up and down, it can drive the fixed rod 604 and the fixed ring block 603 to rotate together through the sliding sphere 605 sliding inside itself. Furthermore, enable the connecting rod 507 to smoothly drive the mounting block 508, the mounting base 509, and the thermal imaging camera body 510 to perform pitching rotation, further increasing the surveying and imaging range of the thermal imaging camera body 510.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope recorded in this specification.

[0058] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
