Description

Technical Field

[0001] This utility model relates to the technical field of drone inspection and survey mounting devices, and in particular to a mounting device for drone inspection and engineering survey equipment. Background Technology

[0002] With the rapid development of drone technology, its application in engineering surveying and infrastructure inspection (such as power lines, bridges, dams, wind turbine blades, etc.) is becoming increasingly widespread. Due to its flexible mobility, efficient operation capabilities, and ability to reach dangerous or complex areas that are difficult for humans to access, drones have become an important supplement and even a replacement for traditional manual inspection methods.

[0003] In UAV inspection and surveying operations, the core tasks rely on various specialized equipment carried by the UAV, such as high-resolution visible light cameras, infrared thermal imagers, multispectral sensors, lidar (LiDAR), ultraviolet imagers, and gas detectors. The performance of these devices directly determines the quality of data acquisition, which in turn affects the accuracy of subsequent analysis and the reliability of engineering decisions. Currently, the common method for integrating these devices onto UAVs is through mounting devices (also known as gimbals or mounts).

[0004] However, existing mounting devices use simple screw locking or snap-fit ​​structures to fix the equipment. Most mounting devices on the market are designed for "one machine, one use", and their mounting base and bayonet size are usually fixed, which can only perfectly fit a certain model or size range of equipment. When different equipment needs to be mounted, it is often necessary to replace the entire gimbal or bracket, which is costly and cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mounting device for unmanned aerial vehicle (UAV) inspection engineering survey equipment. It has the advantages of strong versatility, stable clamping, and convenient operation, and solves the problems of poor equipment compatibility, easy loosening and vibration, and cumbersome switching caused by the simple structure of existing mounting devices.

[0006] The technical solution of this utility model is as follows: a mounting device for unmanned aerial vehicle (UAV) inspection engineering survey equipment, including a mounting frame, a mounting connecting frame fixedly connected to the lower end face of the mounting frame, and retractable telescopic adjustment mechanisms provided at the front and rear ends of the left and right sides of the mounting connecting frame. A fixing block is fixedly connected to the free end of each of the four telescopic adjustment mechanisms, and the four fixing blocks are respectively located at the front and rear ends of the mounting connecting frame. A clamping and fixing mechanism for holding the survey equipment is provided on one side of each of the four fixing blocks, and the clamping and fixing mechanism is connected to a transmission mechanism for driving its synchronous displacement adjustment.

[0007] By adopting the above technical solution, multi-point coordinated clamping of surveying equipment in the horizontal and vertical directions is achieved. The structure layout is reasonable and can adapt to the installation requirements of equipment of different sizes, significantly improving the versatility and adaptability of the mounting device.

[0008] Furthermore, each of the four end feet of the mounting bracket has mounting screw holes inside, and the inner side of the mounting bracket is symmetrically provided with a mounting plate for placing the surveying equipment. The surface of the mounting plate has multiple evenly distributed mounting holes.

[0009] By adopting the above technical solution, a stable connection with the UAV fuselage can be achieved through the mounting screw holes, and an auxiliary mounting position can be provided for equipment that requires platform support through the mounting plate with mounting holes, taking into account both clamp-type and platform-type mounting modes, thus enhancing the functional versatility of the device.

[0010] Furthermore, the telescopic adjustment mechanism includes a telescopic frame fixedly connected to one end of the mounting frame, and the telescopic frame has a movable groove inside, and an adjustment frame is telescopically connected inside the movable groove.

[0011] By adopting the above technical solution, the position of the fixed block can be steplessly adjusted along the movable groove according to the width of the equipment, which initially expands the size adaptability range of the mounting device and lays the foundation for subsequent precise clamping.

[0012] Furthermore, the upper end face of the telescopic frame is provided with multiple through holes, and the inside of the adjusting frame is provided with limiting holes corresponding to the through holes. A spring is provided inside the limiting hole, one end of the spring abuts against the inner wall of the limiting hole, and the other end abuts against a fixing rod that is inserted into the through hole.

[0013] By adopting the above technical solution, the spring force drives the fixing rod to automatically insert into the through hole, realizing the rapid locking and release of the extension length of the adjustment frame. The operation is simple, the positioning is reliable, and it effectively prevents the structure from loosening due to vibration during flight.

[0014] Furthermore, the transmission mechanism includes two double-ended lead screws symmetrically arranged between the left and right fixed blocks. The two ends of the double-ended lead screws are rotatably connected to the corresponding fixed blocks. Threaded blocks are threaded on the outer sides of the left and right sides of the two double-ended lead screws, and the threaded blocks are fixedly connected to the clamping and fixing mechanism.

[0015] By adopting the above technical solution, the positive and negative thread characteristics of the double-ended lead screw are utilized to make the threaded blocks on both sides move synchronously towards or away from each other when the lead screw rotates, thereby driving the clamping and fixing mechanism to achieve centering clamping or loosening, ensuring that the clamping process is stable and symmetrical, and avoiding the equipment being subjected to force deviation.

[0016] Furthermore, each of the two double-ended lead screws is connected to a rotating shaft on one side, and each of the two rotating shafts is fitted with a pulley. The two pulleys are connected to each other by a belt drive, and each of the two rotating shafts is fixedly connected to a rotating handle at its outer end.

[0017] By adopting the above technical solution, only a single rotating handle needs to be operated to drive the double-headed lead screws on both sides to operate in conjunction through the synchronous transmission of the pulley and belt, which simplifies the operation steps, improves clamping efficiency, and ensures a high degree of consistency in the left and right clamping actions.

[0018] Furthermore, the clamping and fixing mechanism includes a clamping block fixedly connected to one end of the threaded block, the clamping block having a storage groove inside, and the inner wall of the storage groove having an internal thread groove.

[0019] By adopting the above technical solution, a stable installation and guiding space is provided for the adjusting screw, enabling the clamping block to have secondary fine-tuning capability, which can be finely adapted to the local contour of the equipment and improve the clamping fit.

[0020] Furthermore, the clamping block is threadedly connected to an adjusting screw via an internal thread groove. A clamping plate is fixedly connected to the end of the adjusting screw facing the surveying equipment, and an auxiliary handle for manual rotation is fixedly connected to the end of the adjusting screw away from the clamping plate.

[0021] By adopting the above technical solution, operators can manually screw in or out the adjusting screw using the auxiliary handle to achieve precise control over the position of the clamping plate, meeting the personalized clamping needs of high-precision installation or irregularly shaped equipment, and enhancing the practicality of the device.

[0022] Furthermore, the clamp is made of an elastic material, and its surface is fixedly connected with multiple anti-slip protrusions.

[0023] By adopting the above technical solutions, the elastic material can buffer the vibration and impact during the flight of the drone, while the anti-slip protrusions increase the friction with the equipment shell, effectively preventing the equipment from slipping or falling off during operation, and ensuring the stability and safety of data acquisition.

[0024] Furthermore, the two mounting plates are detachably installed between the mounting brackets, and the mounting plates are made of lightweight aluminum alloy or carbon fiber composite material.

[0025] By adopting the above technical solution, it is not only convenient to quickly replace or remove the mounting plate according to mission requirements, but also the application of lightweight and high-strength materials significantly reduces the overall load weight, which meets the UAV's requirements for low weight and high rigidity, and is conducive to extending the flight time and improving flight stability.

[0026] The beneficial effects of this utility model are:

[0027] 1. This mounting device for unmanned aerial vehicle (UAV) inspection engineering survey equipment, by setting up a telescopic adjustment mechanism and a synchronous transmission mechanism composed of a double-ended lead screw and threaded block, combined with a manually adjustable clamping and fixing mechanism, achieves rapid adaptation to survey equipment of different sizes and shapes (such as cameras, infrared instruments, lidar, etc.), effectively solving the problem of poor compatibility of the traditional "one machine, one use" mounting method, avoiding frequent replacement of the entire gimbal, and reducing usage costs.

[0028] 2. This is a mounting device for unmanned aerial vehicle (UAV) inspection engineering survey equipment. The clamping plate is made of elastic material and has anti-slip protrusions. While clamping the equipment, it can absorb high-frequency vibrations during flight, prevent the equipment from loosening or shifting, and ensure the continuity and accuracy of data acquisition. The synchronous transmission design ensures that the clamping force on the left and right sides is balanced, avoiding the equipment tilting or damage due to force on one side.

[0029] 3. This is a mounting device for UAV inspection engineering survey equipment. The telescopic adjustment mechanism adopts a quick-lock structure with a spring and a fixed rod and a through hole to achieve stepless length adjustment and rapid positioning. The transmission mechanism can drive the synchronous movement of the two clamping blocks by rotating the handle, simplifying the operation process. The detachable design of the mounting plate further improves the flexibility and deployment efficiency of the device in different mission scenarios. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-4 This embodiment provides a mounting device for unmanned aerial vehicle (UAV) inspection engineering survey equipment, including a mounting frame 1. A mounting connecting frame 2 is fixedly connected to the lower end face of the mounting frame 1. The front and rear ends of the left and right sides of the mounting connecting frame 2 are provided with telescopic adjustment mechanisms 5. The free ends of the four telescopic adjustment mechanisms 5 are fixedly connected with fixing blocks 4. The four fixing blocks 4 are located at the front and rear ends of the mounting connecting frame 2, respectively. One side of each of the four fixing blocks 4 is provided with a clamping and fixing mechanism 9 for clamping the survey equipment. The clamping and fixing mechanism 9 is connected to a transmission mechanism 8 for driving its synchronous displacement adjustment. The four end feet of the mounting frame 1 are provided with mounting screw holes 3. The inner side of the mounting connecting frame 2 is symmetrically provided with a placement plate 6 for placing the survey equipment. The surface of the placement plate 6 is provided with multiple evenly distributed mounting holes 7. Two placement plates 6 are detachably installed between the mounting connecting frame 2. The material of the placement plate 6 is lightweight aluminum alloy or carbon fiber composite material.

[0037] In this embodiment, the mounting bracket 1 can be securely connected to the bottom of the UAV through the mounting screw holes 3, while the detachable lightweight mounting plate 6 provides an auxiliary mounting surface for some surveying equipment that requires platform support (such as small gas detectors or multispectral sensors). At the same time, the four clamping and fixing mechanisms 9, together with the telescopic adjustment mechanism 5 and the transmission mechanism 8, form a multi-dimensional adaptive clamping system, which enables the mounting device to clamp equipment without a base, as well as to carry equipment with a base in conjunction with the mounting plate 6, significantly improving the compatibility of the operation scenario and the flexibility of the task.

[0038] Please see Figures 1-2 In this embodiment, the telescopic adjustment mechanism 5 includes a telescopic frame 51 fixedly connected to one end of the mounting frame 2. The telescopic frame 51 has a movable groove 55 inside, and an adjustment frame 56 is telescopically connected inside the movable groove 55. The upper end face of the telescopic frame 51 has multiple through holes 54. The adjustment frame 56 has a limiting hole corresponding to the through hole 54 inside. A spring 53 is provided inside the limiting hole. One end of the spring 53 abuts against the inner wall of the limiting hole, and the other end abuts against a fixing rod 52 that is inserted into the through hole 54.

[0039] It should be noted that when the clamping width needs to be adjusted, the operator can manually press the fixing rod 52 to disengage it from the through hole 54, and then pull or push the adjusting frame 56 to the appropriate position. After releasing, the spring 53 automatically pushes the fixing rod 52 into the corresponding through hole 54 to achieve quick positioning and locking. This structure can complete the coarse adjustment without tools, is easy to operate, and has reliable locking, effectively preventing the structure from shrinking or loosening due to vibration during flight.

[0040] Please see Figure 1 The transmission mechanism 8 includes two double-ended lead screws 84 symmetrically arranged between the left and right fixed blocks 4. The two ends of the double-ended lead screws 84 are rotatably connected to the corresponding fixed blocks 4. Threaded blocks 85 are threaded on the outer sides of both double-ended lead screws 84. The threaded blocks 85 are fixedly connected to the clamping and fixing mechanism 9. A rotating shaft 81 is connected to one side of each double-ended lead screw 84. A pulley 82 is fitted on the outer side of each rotating shaft 81. The two pulleys 82 are connected to each other by a belt 83. A rotating handle is fixedly connected to the outer end of each rotating shaft 81.

[0041] It should be noted that rotating any of the rotating handles will drive the corresponding pulley 82 to rotate via the rotating shaft 81, and simultaneously drive the other pulley 82 and the double-ended lead screw 84 to rotate via the belt 83. Since the threads at both ends of the double-ended lead screw 84 rotate in opposite directions, the threaded blocks 85 on both sides will move synchronously towards each other, thereby driving the clamping and fixing mechanism 9 to center and clamp the surveying equipment, ensuring that the force is balanced and the equipment is centered during the clamping process, and avoiding image jitter or data distortion caused by off-center loading.

[0042] Please see Figures 3-4 In this embodiment, the clamping and fixing mechanism 9 includes a clamping block 91 fixedly connected to one end of the threaded block 85. The clamping block 91 has a storage groove 92 inside, and the inner wall of the storage groove 92 has an internal thread groove. The clamping block 91 is threadedly connected to an adjusting screw 93 through the internal thread groove. The end of the adjusting screw 93 facing the surveying equipment is fixedly connected to a clamping plate 94. The end of the adjusting screw 93 away from the clamping plate 94 is fixedly connected to an auxiliary handle for manual rotation. The clamping plate 94 is made of elastic material, and its surface is fixedly connected with multiple anti-slip protrusions.

[0043] It should be noted that after the transmission mechanism 8 completes the initial clamping, if it is necessary to further conform to the contour of the equipment or increase the clamping force, the operator can rotate the adjusting screw 93 through the auxiliary handle to move it forward or backward in the storage slot 92, thereby fine-tuning the position of the clamping plate 94. The clamping plate 94, made of elastic material, combined with anti-slip protrusions, can absorb flight vibrations and increase friction to prevent slippage. It is especially suitable for precision surveying equipment with smooth surfaces or curved shells, ensuring stability and safety during long-term operation.

[0044] The working principle of the above embodiments is as follows:

[0045] In use, the adjusting bracket 56 is manually pulled to slide along the movable groove 55 inside the telescopic bracket 51. When the appropriate width is reached, the fixing rod 52 automatically inserts into the corresponding through hole 54 under the elastic force of the spring 53, thereby locking the length of the telescopic adjusting mechanism 5 and initially adjusting the overall layout range of the four clamping and fixing mechanisms 9. The rotating handle in the rotary transmission mechanism 8 drives the rotating shaft 81 to rotate. Through the synchronous transmission of the pulley 82 and the belt 83, the double-headed screws 84 on the left and right sides rotate synchronously. Since the thread directions at both ends of the double-headed screws 84 are opposite... Conversely, the two threaded blocks 85 on it will move towards or away from each other along the lead screw, thereby driving the clamping block 91 connected to it to move closer or further away synchronously, realizing the lateral clamping or loosening of the surveying equipment; rotating the auxiliary handle on the adjusting screw 93 makes the adjusting screw 93 screw in or out in the internal thread groove of the clamping block 91, thereby pushing the clamping plate 94 to press or release the side wall of the surveying equipment. The clamping plate 94 is made of elastic material and has anti-slip protrusions on the surface, which can effectively buffer the vibration and impact during flight and prevent the equipment from slipping, ensuring the stability and safety of data acquisition.

[0046] It should be noted that the transmission and clamping actions of this utility model are all achieved by manual operation, without the need for electric drive or electronic control system; its structural design is entirely based on the principle of mechanical transmission, and the specific operation method is intuitive and easy to implement for those skilled in the art, so the operation details will not be described in detail.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
