Description

Technical Field

[0001] This application relates to the field of aeromagnetic detection equipment, and more specifically to aeromagnetic detection devices based on unmanned aerial vehicles (UAVs). Background Technology

[0002] Airborne magnetic surveying is a geophysical exploration method that uses aircraft equipped with magnetometer systems to measure the strength and gradient of the Earth's magnetic field. Also known as airborne magnetic surveying, this method utilizes fixed-wing aircraft, helicopters, and other platforms carrying equipment such as optically pumped magnetometers and nuclear precession magnetometers to probe deep geological structures. It is widely used in regional structural mapping, mineral exploration, and oil and gas exploration. Its measurement accuracy can reach within 2 nanoteslas, it is not limited by the surface environment, and it can mitigate the influence of surface magnetic inhomogeneities.

[0003] With the development of rotary-wing UAVs, their flexibility and ease of use make them very suitable for integration with aeromagnetic detection equipment, making aeromagnetic detection simpler and more convenient.

[0004] However, existing UAV-based aeromagnetic detection devices have the following problems:

[0005] (1) The equipment is designed as an integrated unit, which makes the overall loading and unloading process more complicated. The overall weight is also large, which makes it difficult to fix and lacks stability, thus posing a safety hazard.

[0006] (2) The telescopic carbon fiber probe and processing module of the equipment are integrated into one device. When storing, the length is too long, and an additional independent long box is required for loading and transportation, which is extremely inconvenient for transportation and on-site deployment.

[0007] (3) The equipment and the drone share a power supply. Since the drone needs to replace its battery every 30-60 minutes, the processing module needs to be restarted frequently. This not only makes it easy to lose data and cause the equipment to run unstablely, but also affects the service life of the processing module.

[0008] (4) It is difficult to conveniently adjust the position of the magnetometer, which makes it unable to collect data normally when it is parallel to the magnetic field;

[0009] (5) The lack of heat preservation structure makes it difficult for the magnetometer to preheat in low temperature environment, which in turn affects its normal operation in low temperature environment. In addition, the lack of heat dissipation structure leads to poor heat dissipation of the magnetometer, which is prone to stop working or even burn out due to high temperature in high temperature environment.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] Example 1

[0051] like Figure 1 , Figure 2 As shown, the drone-based aeromagnetic detection device includes a drone 100 consisting of a drone body 101 and a drone landing gear 102, a mobile power supply 200 fixed to the lower side of the drone body 101, a processing module 300 hanging on the lower front side of the drone body 101, a foldable probe 400 horizontally fixed to the drone landing gear 102, and magnetometer rotation adjustment devices 500 set at both ends of the foldable probe 400.

[0052] Before and after installing and removing the aeromagnetic detection device, the center of gravity of the UAV is located in the middle of the belly of the UAV body. This method can effectively improve the stability of the UAV during operation and avoid flight attitude deformation caused by deviation of the center of gravity.

[0053] like Figure 2 As shown, the power bank 200 consists of a power supply body 201 and two elastic fixing chains 202 for fixing the power supply body 201 to the lower side of the drone body 101. The two elastic fixing chains 202 are arranged horizontally on the lower side of the power supply body 201, and the two ends of the elastic fixing chains 202 are respectively fixed to the left and right sides of the drone body 101. Two locking hooks 103 that cooperate with the elastic fixing chains 202 are respectively provided on both sides of the drone body 101.

[0054] The portable power bank is positioned on the underside or slightly rear of the drone's main body, providing a stable power supply. A single portable battery can power the device for over 24 hours, effectively preventing power outages during battery replacements. The elastic fixing chain can be made of rubber. When its ends are hooked onto the locking hooks, it stretches and deforms. The resulting restoring force allows it to adhere tightly to the outside of the power bank, firmly pressing it against the drone's underside. Furthermore, the weight of the power bank is crucial for adjusting the overall center of gravity. Generally, a power bank of appropriate weight can be selected based on the actual weight distribution. When necessary, additional weights can be added to the power bank for more precise center of gravity adjustment.

[0055] like Figure 2 , Figure 3 As shown, the processing module 300 consists of a processing module body 301, a card plate 302 disposed on the processing module body 301, two sliding groove structures 303 with symmetrically arranged slots and the spacing between the bottoms of the slots matching the width of the card plate 302, and a locking screw 304 disposed on the outer wall of the sliding groove structure 303 and capable of being screwed into the sliding groove structure 303 through the outer wall; the processing module body 301 is electrically connected to the power supply body 201; a fixed gimbal 104 for fixing the two sliding groove structures 303 is disposed on the front side of the UAV body 101.

[0056] The fixed gimbal is a standard accessory for drones, commonly used to support external devices. Those skilled in the art can set it up and use it without any creative effort, so it will not be described in detail here. The processing module is based on existing technology and is mainly used to collect, organize, and transmit data acquired by the three-dimensional fluxgate magnetometer and the full-field atomic magnetometer. Its usage is well-known to those skilled in the art, therefore, they can set it up and use it without any creative effort.

[0057] When using it, first insert the left and right sides of the card plate into the two sliding groove structures respectively. After the card plate slides to the desired position, tighten the locking screws until the locking screws firmly press the card plate against the groove wall of the sliding groove structure. This completes the setting of the main body of the processing module. The reverse operation can complete the disassembly of the main body of the processing module.

[0058] like Figure 4 , Figure 5As shown, the collapsible probe 400 is composed of two middle probes 401 connected by a middle folding member 406 at the inner end, two end probes 402 respectively connected to the outer ends of the two middle probes 401 through end folding members 407, three-dimensional fluxgate magnetometers 403 and full-field atomic magnetometers 404 respectively arranged in the two end probes 402, and a connecting line 405 which is electrically connected to both the three-dimensional fluxgate magnetometer 403 and the full-field atomic magnetometer 404 and whose end passes through the side wall of any one of the middle probes 401 and is electrically connected to the processing module main body 301.

[0059] The folding directions of the two end folding members 407 are the same, and the folding direction of the end folding member 407 is perpendicular to that of the middle folding member 406.

[0060] Both the three-dimensional fluxgate magnetometer and the full-field atomic magnetometer are prior arts in the field. They will be affected to a certain extent due to the metal structure during use. The middle probes and the end probes are both made of non-metallic materials and are carbon fiber rods with high strength. At the same time, the three-dimensional fluxgate magnetometer and the full-field atomic magnetometer are arranged at the ends of the carbon fiber rods to make them as far away from the drone as possible, effectively reducing the influence of the metal materials on the drone on the two magnetometers. In addition, compensation parameters need to be introduced when calculating the collected data to further improve the accuracy of the data.

[0061] In the prior art, the probe generally uses two sets of telescopic carbon fiber rods, and the two sets of telescopic carbon fiber rods are respectively fixed on the left and right sides of the processing module main body. When storing, the two sets of carbon fiber rods need to be shortened to the shortest respectively, but the overall length of the product is still the sum of the lengths of the two carbon fiber rods and the width of the processing module main body. This total length is much greater than the length of the drone storage box, so a storage box with a longer length needs to be selected again to complete the storage of the product. Compared with the prior art, the collapsible probe in this embodiment can finally be folded into a "field" structure during storage, and the length is only the length of one folded probe. On the premise of ensuring its normal use, it can effectively reduce its length during storage, and can also be better stored with the drone in a shorter storage box during storage, greatly reducing the difficulty of carrying and transporting the product.

[0062] Both the middle folding member and the end folding member are prior arts, and structures such as carbon tube folding members, hinges, folding hinges, etc. that can be fixed after folding can be selected. Those skilled in the art can complete their setting and use according to the above description, so no further elaboration will be made here.

[0063] The three-dimensional fluxgate magnetometer 403 and the full-field atomic magnetometer 404 are respectively disposed in two auxiliary probe rods 408, and the heads of the three-dimensional fluxgate magnetometer 403 and the full-field atomic magnetometer 404 extend out of the two auxiliary probe rods 408 respectively; a heat-insulating and vibration-damping layer 409 is filled between the auxiliary probe rods 408 and the end probe rods 402.

[0064] The thermal insulation and vibration damping layer can be made of elastic structures with thermal insulation capabilities, such as sponge pads / sleeves or rubber pads / sleeves. This ensures that the magnetometer will not shift its position due to bumps during product use, and also ensures that the preheating heat of the magnetometer is not easily lost in low-temperature environments, effectively guaranteeing the stability of the product's start-up and operation in low-temperature and ultra-low-temperature environments.

[0065] like Figure 7 , Figure 8 As shown, the magnetometer rotation adjustment device 500 consists of a fixed sleeve 501 fixed to the outer wall of the end probe 402 by screws, and a rotating head 502 that is cylindrical in shape, cooperates with the fixed sleeve 501, and can rotate within the fixed sleeve 501; the cylindrical body of the rotating head 502 is inserted into the fixed sleeve 502, and the bottom of the cylinder is located outside the fixed sleeve; the auxiliary probe 408 is inserted into and fixed in the cylindrical body of the rotating head 502 by interference fit, and the heads of the three-dimensional fluxgate magnetometer 403 and the full-field atomic magnetometer 404 are respectively located in the cylindrical bodies of the two rotating heads 502.

[0066] The fixed sleeve and the rotating head are secured and connected by an elastic retaining spring. The inner and outer sides of the elastic retaining spring are respectively engaged in the annular grooves on the opposing surfaces of the fixed sleeve and the rotating head, ensuring that the rotating head can rotate circumferentially without detaching from the fixed sleeve axially. By rotating the rotating head, the magnetic force detection direction of the magnetometer can be quickly and effectively adjusted, effectively avoiding the situation where the magnetometer cannot accurately collect magnetic force information when the bottom magnetic field is parallel to the magnetometer.

[0067] The bottom of the rotating head 502 is provided with a groove, and a rotating disk 503 is rotatably disposed in the groove; a rotating handle 504 is provided on the outer side of the rotating disk 503 along the diameter direction, and a ventilation hole array 505 penetrating the rotating disk 503 is provided on the outer side of the rotating disk 503, and the overall area of ​​the ventilation hole array 505 is less than 1 / 2 of the area of ​​the outer side of the rotating disk 503; a hole array matching the ventilation hole array 505 is provided on the bottom of the rotating head 502.

[0068] The rotating disc controls the ventilation and heat dissipation function of the product. When the ventilation hole array on the disc aligns with the hole array on the bottom of the rotating head cylinder, the ventilation and heat dissipation function is activated. External airflow enters one end probe through the holes, passes through all the end probes and the middle probe, and then exits through the holes of the other end probe, thus achieving a cooling effect. This prevents the product from malfunctioning due to overheating in high-temperature environments. Conversely, when heat dissipation is not required, simply offset the ventilation hole array on the disc from the hole array on the bottom of the rotating head cylinder. Alternatively, the hole array on the bottom of the rotating head cylinder can be replaced by a fan-shaped through hole. Using a through hole effectively reduces the difficulty of aligning the ventilation hole array and simplifying ventilation adjustment.

[0069] like Figure 6 As shown, the front of the drone tripod 201 is provided with a probe clamp 105 that can horizontally clamp the central probe 401, and a T-shaped platform 106 is provided on the back of the drone tripod 201 opposite to the probe clamp 105; an elastic silicone chain 107 is fitted on the T-shaped platform 106, and the other end of the elastic silicone chain 107 is penetrated by the central probe 401.

[0070] The probe clamp, a current technology, serves to hold the central probe and keep it horizontal on the drone. The elastic silicone chain not only further enhances the stability of the fixation but also provides initial support and restraint before the probe is secured into the clamp, further reducing the difficulty of installation.

[0071] Example 2

[0072] The difference between this embodiment and embodiment 1 is that the card plate 302 has a positioning port on each of its left and right sides that cooperates with the locking screw 304.

[0073] This allows the locking screw to penetrate the positioning port vertically or insert horizontally after tightening, further improving the accuracy and stability of the positioning and better ensuring that the main body of the processing module will not fall off during use.

[0074] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0075] Furthermore, the specific embodiments described above are exemplary.
