Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a quick assembly and disassembly structure for a wide-area receiver used in UAVs. Background Technology

[0002] Semi-airborne wide-area electromagnetic detection is a geophysical exploration technology that combines high-power ground transmission with airborne mobile reception. During operation, a wide-area receiver needs to be installed on the bottom of the UAV through a fixed structure, and collect the electromagnetic response signals fed back by the underground medium as the UAV cruises.

[0003] In field operations, wide-area receivers require frequent installation, disassembly, battery replacement, equipment maintenance, relocation, and model adaptation switching. Current methods for fixing the drone to the wide-area receiver primarily use bolts to secure it to the drone's bottom or mounting plate. In field operations, this necessitates frequent installation, disassembly, relocation, maintenance, and experimental preparation. Traditional bolted fixing structures require repeated tightening and loosening with tools, leading to issues such as loose or lost fasteners, compromising the convenience and efficiency of field operations. Utility Model Content

[0004] In view of this, the present invention provides a quick assembly and disassembly structure for a wide-area receiver for unmanned aerial vehicles (UAVs), which enables the quick assembly and disassembly of the wide-area receiver and improves the convenience and continuity of semi-aerial electromagnetic exploration field operations.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A quick-assembly and fixing structure for a wide-area receiver for unmanned aerial vehicles (UAVs) includes a UAV and a wide-area receiver mounted on the underside of the UAV. The key feature is that a fixed base is fixed to the underside of the UAV, and two sets of parallel slide rails are fixed on the fixed base. Each set of slide rails has a groove extending along its length on one side facing each other. One end of each groove is open, and the other end is closed. A connecting plate is fixed to the top of the wide-area receiver, and both ends of the connecting plate are slidably inserted into the two sets of slide rails.

[0007] The slide rail is threaded with a locking pin. When the connecting plate is inserted into the slide groove and abuts against the closed end, the locking pin is screwed inward to fix and restrict the connecting plate in the slide groove.

[0008] With the above structure, this sliding plug-in installation method, combined with the locking pin screw tightening, can easily and quickly complete the installation and disassembly of the wide-area receiver, greatly shortening the disassembly and assembly time in the field and improving the efficiency of field relocation and equipment maintenance.

[0009] As a preferred embodiment, each set of slide rails shall be provided with at least two locking pins;

[0010] And / or, the slide rail is provided with a transverse through hole, and a nut is fixed at the outer end of the through hole. The locking pin is threaded onto the nut, and by turning the locking pin, its inner end can extend into the slide groove. The above structure ensures the stability and safety of the wide-area receiver mounting and fixing.

[0011] Preferably, each set of slide rails is provided with two locking pins, which are spaced apart along the extension direction of the slide rail. One locking pin is used to lock the connecting plate, and the other locking pin is used to stop the connecting plate at its outer end. With the above structure, the two locking pins can form a double lock, which can both lock the connecting plate in the installation position and prevent the connecting plate from sliding outward.

[0012] Preferably, the connecting plate has a locking notch on one side corresponding to the slide rail. When the connecting plate is inserted along the slide groove until it abuts against the closed end, the locking pin is aligned with the locking notch and can be screwed into it. This structure further ensures the stability of the equipment mounting.

[0013] Preferably, a support frame is fixed to the underside of the UAV, and the bottom of the support frame has a hollow structure to provide operating space for the installation and removal of the wide-area receiver. This structure facilitates the installation and removal operations for personnel and also provides support for the UAV fuselage when it lands, preventing the fuselage from directly interfering with the wide-area receiver upon landing.

[0014] Preferably, the support frame is provided in two sets, symmetrically arranged, with both sets extending outwards at an angle. This structure improves the stability of the UAV landing support, resulting in a more balanced stress distribution on the fuselage.

[0015] Preferably, the mounting base includes a mounting frame fixed to the underside of the UAV, a base plate is fixedly mounted on the mounting frame, and two sets of slide rails are symmetrically arranged at both ends of the underside of the base plate.

[0016] And / or the connecting plate is suspended on top of the wide-area receiver via four sets of positioning posts. Using the above structure, the mounting base adopts a split structure of the mounting frame and the base plate, combined with a thin design, resulting in a lightweight and compact overall structure that is easy to carry and transport in the field. At the same time, the split structure also facilitates manufacturing and subsequent maintenance. The symmetrical arrangement of slide rails at both ends of the base plate further enhances the reliability of the overall structure, making the sliding contact of the connecting plate smoother and the force distribution more even.

[0017] Preferably, the UAV has circumferentially distributed outriggers, with at least three suspension ropes suspended from the lower outer ends of the outriggers. The lower ends of each suspension rope are connected to a magnetic sensor, which is electrically connected to the wide-area receiver. A stabilizing frame is provided between the suspension ropes, extending radially outward to support each rope, forming a multi-directional stable tension structure. This structure effectively suppresses the rotation and lateral sway of the magnetic sensor during flight, improving its attitude stability and ensuring the consistency and accuracy of electromagnetic data acquisition. Furthermore, by suspending the magnetic sensor away from the UAV body via the ropes, electromagnetic interference from the UAV body is reduced, ensuring signal reception range and quality.

[0018] Preferably, the stabilizer includes a central connecting seat, on which support rods, the same number as the suspension ropes, are detachably mounted circumferentially. The outer ends of each support rod correspond one-to-one with each suspension rope, and the outer ends of the support rods are detachably connected to the suspension ropes. With this structure, the stabilizer uses a central connecting seat and multiple support rods that can be detachably assembled, allowing for rapid assembly during field operations and disassembly to reduce its size for easy transport and storage.

[0019] Preferably, the support rod has a connecting component at one end away from the central connecting seat. The connecting component has a connecting through hole with an opening on one side. The suspension rope is inserted into the connecting through hole. The connecting component has a limiting pin, the end of which can extend into the connecting through hole. The limiting pin prevents the suspension rope from slipping out of the opening of the connecting through hole. This structure allows for convenient assembly and disassembly, meeting the needs of rapid field operations.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The quick-assembly and fixing structure for the wide-area receiver for UAVs provided by this utility model, through the sliding plug-in installation method and the locking pin screw tightening, can conveniently and quickly complete the installation and disassembly of the wide-area receiver, greatly shortening the disassembly and assembly time in the field and improving the convenience and continuity of semi-aerial electromagnetic exploration field operations.

[0022] 2. The quick assembly and disassembly structure for the wide-area receiver for UAVs provided by this utility model has an open end at one end of the slide to facilitate the sliding of the connecting plate, and a closed end at the other end to limit the sliding stroke of the connecting plate and ensure accurate installation position.

[0023] 3. The mounting base adopts a split structure of mounting frame and base plate, combined with a thin design, making it lightweight and compact, which is convenient for carrying and transporting in the field. At the same time, the split structure also facilitates processing, manufacturing and later maintenance.

[0024] 4. The hollow design at the bottom of the support frame not only provides ample operating space for the installation and removal of the wide-area receiver, making it convenient for operators to complete the installation and removal operations, but also provides support for the fuselage when the UAV lands, preventing the fuselage from directly interfering with the wide-area receiver when it lands directly.

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figure 1 The diagram illustrates a quick-assembly and disassembly structure for a wide-area receiver used in unmanned aerial vehicles (UAVs). It includes a UAV 1 and a wide-area receiver 2, with the receiver 2 detachably mounted on the underside of the UAV 1. Combined with... Figures 2 to 4As shown, a mounting base 3 is fixedly installed on the lower side of the UAV 1. Two sets of parallel slide rails 4 are fixedly mounted on the lower side of the mounting base 3. Each set of slide rails 4 has a groove 4a extending along its length on one side facing each other. One end of the groove 4a is an open end 4a1, and the other end is a closed end 4a2. A connecting plate 5 is fixedly installed on the top of the wide-area receiver 2. Both ends of the connecting plate 5 are slidably inserted into the two sets of slide rails 4a. Locking pins 6 are threaded onto the side of the slide rails 4. When the connecting plate 5 is inserted along the groove 4a until it abuts against the closed end 4a2, the locking pins 6 are screwed inward to fix and restrict the connecting plate 5 within the groove 4a.

[0035] Based on the above structural design, the installation and disassembly process of the wide-area receiver 2 is as follows: (Refer to...) Figure 4 and Figure 5 First, insert the connecting plate 5 into the slide groove 4a. The connecting plate 5 is inserted from the open end 4a1 of the slide groove 4a until it abuts against the closed end 4a2, reaching the predetermined installation position. Then, screw the locking pin 6 inward, and the locking pin 6 will press against the side of the connecting plate 5, locking the connecting plate 5 into the slide groove 4a. For disassembly, rotate the locking pin 6 outward, moving it away from the side of the connecting plate 5, allowing the connecting plate 5 to slide out along the slide groove 4a, completing the disassembly of the wide-area receiver 2. This sliding insertion installation method, combined with the screw-tightening locking pin 6, allows for convenient and quick installation and disassembly of the wide-area receiver 2, significantly reducing the time spent on disassembly and assembly in the field and improving the efficiency of field relocation and equipment maintenance. The open end 4a1 at one end of the slide groove 4a facilitates the insertion of the connecting plate 5, while the closed end 4a2 at the other end limits the sliding stroke of the connecting plate 5, ensuring accurate installation.

[0036] Combination Figure 3 and Figure 5 As shown, in this embodiment, the connecting plate 5 is suspended on the top of the wide-area receiver 2 by four sets of positioning posts b, which can reserve a gap for insertion operation at both ends of the connecting plate 5 so that both ends of the connecting plate 5 can be inserted into the slide groove 4a.

[0037] Furthermore, by Figure 3 As can be seen, the mounting base 3 includes a mounting frame 3a fixed to the lower side of the UAV 1, with a base plate 3b fixedly mounted at the lower end of the mounting frame 3a. Two sets of slide rails 4 are symmetrically arranged at both ends of the lower side of the base plate 3b. In this embodiment, both the base plate 3b and the connecting plate 5 are thin plates. With this design, the mounting base 3 adopts a split structure of the mounting frame 3a and the base plate 3b, and combined with the thin design, the overall weight is light and the size is small, making it convenient for carrying and transporting in the field. At the same time, the split structure also facilitates processing, manufacturing, and later maintenance. The symmetrical arrangement of the slide rails 4 at both ends of the base plate 3b can further improve the reliability of the overall structure, making the sliding fit of the connecting plate 5 more stable and the force distribution more uniform.

[0038] To ensure the stability and safety of the mounting and fixing of the wide-area receiver 2, each set of slide rails 4 is equipped with at least two locking pins 6.

[0039] Installation structure reference for locking pin 6 Figure 4 The slide rail 4 has a transverse through hole 4b, and a nut 4c is fixed to the outer end of the through hole 4b. The locking pin 6 is threaded onto the nut 4c. By turning the locking pin 6, the inner end of the locking pin 6 can extend into the slide groove 4a. This design makes the operation simple and smooth, and the locking force stable and controllable, making it suitable for the needs of field operations.

[0040] Please refer to Figure 4 In this embodiment, each set of slide rails 4 is provided with two locking pins 6. The two locking pins 6 are arranged at intervals along the extension direction of the slide rail 4. One of the locking pins 6 is used to lock the connecting plate 5, and the other locking pin 6 is used to stop at the outer end of the connecting plate 5. The two locking pins 6 can form a double lock, which can lock the connecting plate 5 in the installation position and prevent the connecting plate 5 from sliding outward, further improving the safety of the equipment during high-altitude flight operations.

[0041] For details, please refer to the following: Figure 4 The connecting plate 5 has a locking notch 5a on one side corresponding to the slide rail 4. When the connecting plate 5 is inserted along the slide groove 4a until it abuts against the closed end 4a2, the locking pin 6 used to lock the connecting plate 5 is aligned with the locking notch 5a and can be screwed into the locking notch 5a. With this design, the locking pin 6 has higher locking positioning accuracy and the equipment is more securely fixed.

[0042] like Figure 1 and 2 As shown, a support frame 1a is fixed on the lower side of the UAV 1. The bottom of the support frame 1a has a hollow structure, which can not only reserve sufficient operating space for the wide area receiver 2 during disassembly and assembly, making it convenient for operators to complete the disassembly and assembly operations, but also provide support for the fuselage when the UAV 1 lands, preventing the fuselage from directly landing and interfering with the wide area receiver 2.

[0043] See again Figure 1 and 2 In this embodiment, there are two sets of support frames 1a, which are symmetrically arranged and extend outward at an angle. This design improves the stability of the UAV 1 landing support, makes the force on the fuselage more balanced, and further expands the operating space of the bottom hollow area, making it easier to assemble and disassemble the wide-area receiver 2.

[0044] To improve the signal reception range of the device, a magnetic sensor 8 is also installed below the drone 1. The magnetic sensor 8 is electrically connected to the wide-area receiver 2 and is suspended below the drone 1 by a suspension rope 7. For specific installation methods, please refer to [reference needed]. Figure 6The UAV 1 has multiple circumferentially distributed extended arms 1b, with suspension ropes 7 suspended from the lower outer ends of each arm 1b. There are at least three suspension ropes 7, evenly distributed around the lower circumference of the UAV 1. A magnetic sensor 8 is connected to the lower end of each suspension rope 7. A stabilizing frame 9 is provided between the suspension ropes 7, extending radially outward to support each suspension rope 7, forming a multi-directional stable tension structure. This structural design effectively suppresses the rotation and lateral sway of the magnetic sensor 8 during flight, improving its attitude stability and ensuring the consistency and accuracy of electromagnetic data acquisition. Furthermore, by suspending the magnetic sensor 8 away from the UAV 1 body via ropes, electromagnetic interference from the UAV 1 is reduced, ensuring signal reception range and quality.

[0045] In this embodiment, the number of suspension ropes 7 is four.

[0046] like Figure 6 and 8 As shown, the stabilizing frame 9 includes a central connecting seat 9a, on which four support rods 9b are detachably mounted, the number of which is the same as the number of suspension ropes 7. The outer end of each support rod 9b corresponds one-to-one with each suspension rope 7, and the outer ends of the support rods 9b are detachably connected to the suspension ropes 7. The stabilizing frame 9 employs a detachable assembly structure of the central connecting seat 9a and multiple support rods 9b, allowing for quick assembly during field operations and easy disassembly for storage and transport. The one-to-one connection between the support rods 9b and the suspension ropes 7 ensures uniform support force across the ropes, resulting in reliable rope stabilization.

[0047] In practical applications, the central connecting seat 9a and the support rod 9b can be assembled using commonly used detachable connection methods in the field, such as plug-in connection, threaded connection, and elastic snap-fit ​​connection. The specific connection structures are all conventional technical means in the field and will not be described in detail here.

[0048] Please refer to Figure 7 and 8 The support rod 9b has a connecting component 9c at its end furthest from the central connecting seat 9a. This connecting component 9c is used to connect the suspension rope 7. The connecting component 9c has a connecting through hole 9c1, and an opening a is provided on one side of the connecting through hole 9c1, through which the suspension rope 7 can be inserted. Furthermore, the connecting component 9c has a limiting pin 9c2, the end of which can extend into the connecting through hole 9c1. Tightening the limiting pin 9c2 inward can lock the suspension rope 7, preventing it from coming out of the opening of the connecting through hole 9c1. During disassembly, loosening the limiting pin 9c2 allows the suspension rope 7 to be removed from the opening a.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
