Description

Technical Field

[0001] This utility model relates to the field of aeromagnetic detection technology, and in particular to an aeromagnetic detection device for a multi-rotor unmanned aerial vehicle. Background Technology

[0002] Airborne magnetic surveying, also known as airborne magnetic measurement or airborne magnetic exploration, is the earliest, most mature and most widely used magnetic surveying method in airborne geophysical exploration. It is a geophysical method that involves mounting an airborne magnetometer and its supporting auxiliary equipment on an aircraft to measure the intensity or gradient of the geomagnetic field over the measurement area according to a pre-set survey line and altitude.

[0003] Traditional long-pole aeromagnetic detection devices are generally installed directly under the belly of multi-rotor UAVs. The detection poles on these devices are typically connected and secured using straps, which is inefficient and carries the risk of loosening. Furthermore, there is a lack of protection for the bottom of the long-pole aeromagnetic detection device. Since the device is mounted on the bottom, it is at risk of accidental damage when the multi-rotor UAV lands on uneven ground. In light of these factors, this application proposes an aeromagnetic detection device for multi-rotor UAVs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-rotor unmanned aerial vehicle (UAV) aeromagnetic detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-rotor unmanned aerial vehicle (UAV) aeromagnetic detection device includes an aeromagnetic detection device body installed on the bottom of the UAV. The aeromagnetic detection device body includes a detection box and a detection rod electrically connected to the detection box. The UAV includes a mounting bracket. Buffer pads are glued and fixed to both sides of the bottom of the mounting bracket. The elasticity of the buffer pads can buffer and dissipate the hard impact force when the UAV lands. Two detachable mounting mechanisms for connecting to the mounting bracket are sleeved on the detection rod. Two mounting blocks are fixedly connected to the inner side of the mounting bracket, and the mounting blocks are sleeved on the corresponding detachable mounting mechanisms. Multiple anti-collision buffer mechanisms for collision prevention are fixedly connected to the bottom of the detection rod.

[0007] Preferably, the detachable mounting mechanism includes two semicircular rings sleeved on the probe rod. Anti-slip pads are glued to the inner side of the semicircular rings, and the inner side of the anti-slip pads is in close contact with the outer side of the probe rod. The friction between the anti-slip pads and the probe rod, combined with the clamping force between the two semicircular rings, enables the connection between the semicircular rings and the probe rod. Two sets of fixing components are fixedly connected to the front of the two semicircular rings on the same detachable mounting mechanism. A retaining sleeve is fixedly connected to the bottom of the lower semicircular ring, and a mounting block is sleeved on the corresponding retaining sleeve. The side of the two retaining sleeves that is close to each other is open. An elastic retaining component is movably fitted inside the retaining sleeve. The lower semicircular ring is sleeved on the corresponding elastic retaining component, which is used to connect the semicircular ring and the mounting block.

[0008] Preferably, the elastic clamping assembly includes an L-shaped clamping rod that is movably clamped in a sleeve, a mounting block that is movably sleeved on the corresponding L-shaped clamping rod, the L-shaped clamping rod restricting the corresponding sleeve, a rectangular hole being provided on one side of the lower semi-circular ring, a positioning rod being movably sleeved in the rectangular hole, the ends of the two positioning rods that are close to each other being fixedly connected to the inner side of the corresponding L-shaped clamping rod, the positioning rods providing a lateral guiding effect for the corresponding L-shaped clamping rod, a fixing block being fixedly installed in the rectangular hole, and a first spring being fixedly connected between the ends of the two positioning rods that are far from each other and the corresponding fixing block, when the first spring is in a stretched state and the tension is released, the corresponding L-shaped clamping rod can be driven to reset through the positioning rod.

[0009] Preferably, the anti-collision buffer mechanism includes an elastic U-shaped rubber ring bonded and fixed to the bottom of the probe rod, a protective plate bonded and fixed to the bottom of the elastic U-shaped rubber ring, and multiple buffer springs fixedly connected between the top inner wall and the bottom inner wall of the elastic U-shaped rubber ring. The bottom position of the protective plate is 5-10cm lower than the bottom position of the probe rod, so that when the bottom of the protective plate contacts the ground, the bottom of the probe rod will not contact the ground.

[0010] Preferably, the fixing component includes two threaded sleeves, which are fixedly connected to the front side of the corresponding semicircular rings. The two threaded sleeves, which are opposite each other, are threaded with the same fixing bolt. By cooperating with the fixing bolt and the threaded sleeves, the fixed connection between the two opposite semicircular rings can be achieved.

[0011] Preferably, a male hook and loop fastener is glued to the bottom of the probe rod, and a female hook and loop fastener is glued to the bottom of the male hook and loop fastener. The bottom of the female hook and loop fastener is glued to the top of the corresponding elastic ring. The probe rod and the elastic ring can be fixedly connected by the cooperation of the male and female hook and loop fasteners.

[0012] Preferably, the rear sides of the two opposing semicircular rings are fixedly connected to the same hinge, and the two opposing semicircular rings are rotated and installed through the corresponding hinges.

[0013] Compared with existing technologies, the beneficial effects of this utility model are:

[0014] 1. With the cooperation of the detachable installation mechanism and the installation block, the probe rod and the mounting bracket can be disassembled and assembled by simple push and pull, without the need for binding with fixing straps. Compared with the binding method in the existing technology, its installation and fixing efficiency is significantly improved.

[0015] 2. By setting up an anti-collision buffer mechanism, when the multi-rotor UAV carries the aeromagnetic detection device to land on a raised ground, it can buffer and unload the bottom of the detection rod, which can reduce the phenomenon of direct collision damage between the detection rod and the ground. At the same time, in conjunction with the elastic buffering and unloading of the buffer pad, it can effectively reduce the risk of large hard shock impact force being transmitted to the detection rod and causing damage to it, thus improving the safety of the detection rod during use.

[0016] This invention, through a series of structural designs, enables quick assembly and disassembly of the probe rod and mounting bracket via a simple push-pull method, improving installation and fixing efficiency. It also effectively avoids the risk of separation due to loose binding and provides effective buffering and stress relief protection for the probe rod when the multi-rotor UAV carries the aeromagnetic detection device to a raised ground, thus reducing the risk of damage due to accidental collision or hard vibration impact and improving the safety of the probe rod during use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A multi-rotor unmanned aerial vehicle (UAV) aeromagnetic detection device includes an aeromagnetic detection device body 1 mounted on the bottom of the UAV 100. The aeromagnetic detection device body 1 includes a detection box 102 and a detection rod 101 electrically connected to the detection box 102. The UAV 100 includes a mounting bracket 103. Buffer pads 2 are glued and fixed to both sides of the bottom of the mounting bracket 103. The elasticity of the buffer pads 2 can buffer and dissipate the hard impact force during landing of the UAV 100. Two detachable mounting mechanisms 4 are sleeved on the detection rod 101 for connection to the mounting bracket 103. Two mounting blocks 403 are fixedly connected to the inner side of the mounting bracket 103. The mounting blocks 403 are sleeved on the corresponding detachable mounting mechanisms 4. The detachable mounting mechanism 4 includes two semi-circular rings 401 sleeved on the detection rod 101. Anti-slip rubber pads 402 are glued and fixed to the inner side of the semi-circular rings 401. The inner side of the anti-slip pad 402 is in close contact with the outer side of the probe rod 101. The friction between the anti-slip pad 402 and the probe rod 101, combined with the clamping force between the two semi-circular rings 401, enables the connection between the semi-circular rings 401 and the probe rod 101. The front sides of the two semi-circular rings 401 located on the same set of detachable mounting mechanisms 4 are fixedly connected to two sets of fixing components. The fixing components include two threaded sleeves 410. The threaded sleeves 410 are fixedly connected to the front sides of the corresponding semi-circular rings 401. The two upper and lower opposite threaded sleeves 410 are threaded with the same fixing bolt 411. The fixing bolt 411 and the threaded sleeve 410 cooperate to achieve the fixed connection between the upper and lower opposite semi-circular rings 401. The rear sides of the two upper and lower opposite semi-circular rings 401 are fixedly connected to the same hinge. The two upper and lower opposite semi-circular rings 401 are rotated and installed through the corresponding hinge.

[0024] A retaining sleeve 404 is fixedly connected to the bottom of the lower semicircular ring 401. A mounting block 403 is fitted onto the corresponding retaining sleeve 404. The top of the mounting block 403 has a slot, the inner wall of which is in movable contact with the outer side of the corresponding retaining sleeve 404. The sides of the two retaining sleeves 404 that are close to each other are open. An elastic locking assembly is movably fitted inside the retaining sleeve 404. The lower semicircular ring 401 is fitted onto the corresponding elastic locking assembly. The elastic locking assembly includes an L-shaped locking rod 405 that is movably fitted inside the retaining sleeve 404. The mounting block 403 is movably fitted onto the corresponding L-shaped locking rod 405. Rectangular through holes are formed on the inner walls of the sides of the two slots that are close to each other. The inner walls of the rectangular through holes are in slidable contact with the outer side of the corresponding L-shaped locking rod 405. The L-shaped locking rod 405 is used to pass through the corresponding L-shaped locking rod 405, which restricts the corresponding locking sleeve 404. A rectangular hole 407 is opened on one side of the lower semi-circular ring 401. A positioning rod 406 is movably fitted in the rectangular hole 407. The ends of the two positioning rods 406 that are close to each other are fixedly connected to the inner side of the corresponding L-shaped locking rod 405. The positioning rod 406 plays a lateral guiding role for the corresponding L-shaped locking rod 405. A fixing block 408 is fixedly installed in the rectangular hole 407. A first spring 409 is fixedly connected between the ends of the two positioning rods 406 that are far from each other and the corresponding fixing block 408. When the first spring 409 is in a stretched state and the tension is released, the corresponding L-shaped locking rod 405 can be driven to reset through the positioning rod 406.

[0025] Multiple anti-collision buffer mechanisms 3 are fixedly connected to the bottom of the probe 101. Each anti-collision buffer mechanism 3 includes an elastic loop rubber ring 302 adhesively fixed to the bottom of the probe 101. A male Velcro 304 is adhesively fixed to the bottom of the probe 101, and a female Velcro 304 is adhesively fixed to the bottom of the male Velcro 304. The bottom of the female Velcro 304 is adhesively fixed to the top of the corresponding elastic loop rubber ring 302. The cooperation of the male and female Velcro 304 achieves a fixed connection between the probe 101 and the elastic loop rubber ring 302. A protective plate 301 is adhesively fixed to the bottom of the elastic loop rubber ring 302. Multiple buffer springs 303 are fixedly connected between the inner top and inner bottom walls of the elastic loop rubber ring 302. The elastic loop rubber ring 302 and the buffer springs 303... The elasticity of the protective plate 301 can buffer and dissipate the impact force of hard vibration during landing. The bottom position of the protective plate 301 is 5-10cm lower than the bottom position of the detection rod 101, so that when the bottom of the protective plate 301 contacts the ground, the bottom of the detection rod 101 will not contact the ground. Through a series of structural settings, this utility model can quickly complete the assembly and disassembly of the detection rod 101 and the mounting bracket 103 by simple push and pull, improving the installation and fixing efficiency, and effectively avoiding the risk of separation due to loose binding. It can also effectively buffer and dissipate the force of the detection rod 101 when the multi-rotor UAV 100 carries the aeromagnetic detection device body 1 to land on a raised ground, effectively reducing the risk of damage due to accidental collision or hard vibration impact, and improving the safety of the detection rod 101 during use.

[0026] Working principle: Before fixing, after fixing the detection box 102, when connecting and fixing the detection rod 101, the detachable mounting mechanism 4 is connected to the detection rod 101. First, pull the L-shaped locking rod 405 towards each other. The L-shaped locking rod 405 drives the corresponding positioning rod 406 to slide in the rectangular hole 407. While the positioning rod 406 slides, it stretches the corresponding first spring 409. At the same time, the L-shaped locking rod 405 separates from the corresponding sleeve 404. At this time, the detection rod 101 can be moved downward. The detection rod 101 drives the two detachable mounting mechanisms 4 to move downward. The sleeve 404 on the detachable mounting mechanism 4 moves downward into the slot on the mounting block 403. At this time, the lower semi-circular ring 401 contacts the top of the corresponding mounting block 403. Then, release the tension on the L-shaped locking rod 405. At this time, the elastic force of the first spring 409 in the stretched state drives the corresponding positioning rod 406 to move laterally. The positioning rod 406 drives the corresponding L-shaped locking rod 405 to engage in the slot. Inside sleeve 404, L-shaped locking rod 405 engages with corresponding sleeve 404. At this time, L-shaped locking rod 405 vertically restricts corresponding sleeve 404, and the slot on mounting block 403 horizontally restricts sleeve 404, thereby achieving connection between probe rod 101 and two mounting blocks 403 on mounting bracket 103. When disassembling later, the two L-shaped locking rods 405 can be pulled closer to each other again, so that L-shaped locking rods 405 move out of corresponding sleeve 404 and separate from mounting block 403, thus releasing the fixation of probe rod 101. Moving probe rod 101 upward drives detachable mounting mechanism 4 upward, and sleeve 404 on detachable mounting mechanism 4 separates from corresponding mounting block 403, thereby removing probe rod 101. The probe rod 101 can be quickly connected to mounting bracket 103 by simple push-pull locking, which facilitates personnel operation, improves installation and fixing efficiency, and effectively avoids the risk of separation due to loose binding.

[0027] After installation, the multi-rotor UAV 100 can lift up and drive the aeromagnetic detection device 1 to work. When the multi-rotor UAV 100 drives the aeromagnetic detection device 1 to land on the raised ground, since the bottom of the protective plate 301 is lower than the bottom of the detection rod 101, the protective plate 301 will first contact the ground and impact. Under the impact force, the protective plate 301 compresses the corresponding elastic ring 302, which in turn compresses the corresponding buffer spring 303. In addition, the mounting bracket 103 is squeezed when it lands. Under the elastic force of the elastic ring 302, the buffer spring 303 and the buffer pad 2, the impact force during landing can be effectively buffered and unloaded, reducing the risk of damage to the detection rod 101 caused by the large impact force of hard vibration. At the same time, it can reduce the phenomenon of direct collision between the detection rod 101 and the ground, and improve the safety of the detection rod 101 during use.

[0028] Furthermore, the semicircular ring 401 is fixedly connected to the probe rod 101 through a corresponding fixing component and an anti-slip pad 402. In the future, the fixing bolt 411 on the fixing component can be rotated to separate it from the threaded sleeve 410, thereby releasing the fixing of the semicircular ring 401. Then, the semicircular ring 401 can be rotated to separate the corresponding anti-slip pad 402 from the probe rod 101, and the detachable mounting mechanism 4 can be removed from the probe rod 101. The removed detachable mounting mechanism 4 can be reused on other probe rods 101, improving the flexibility of use.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
