Description

Technical Field

[0001] The invention belongs to the technical field of probe brackets, in particular to a probe bracket based on aeromagnetic gradient measurement of a flying platform. Background Art

[0002] Platform aeromagnetic gradient measurement, as an advanced technology used in the field of geophysical exploration, mainly relies on manned or unmanned aerial vehicles to operate in the air. This technology uses professional probes equipped with platform aeromagnetic gradient measurement systems to accurately measure subtle changes in the earth's magnetic field. These probes are firmly installed on the left and right wingtips through a bracket structure.

[0003] However, the above technology often has the following defects: when the current probe bracket is in use, the probe needs to be first firmly installed on the bracket, and then the entire bracket is accurately assembled to the wing position. However, in actual operation, if the installation position of the bracket deviates, causing the probe rod connected to the probe to exceed the preset position of the wing, the air resistance borne by the probe rod will be significantly increased during the operation of the aircraft. This additional resistance may not only induce violent vibration of the probe rod, but also has the potential risk of causing damage to the probe rod structure or even breakage. In view of the complexity and tediousness of adjusting the position of the installed bracket, the present invention provides a probe bracket based on aeromagnetic gradient measurement of a flight platform.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Embodiment 1: Figures 1 to 6 As shown, a probe bracket based on aeromagnetic gradient measurement of a flight platform described in an embodiment of the present invention comprises a pair of connecting frames 1, which can be installed on a wing by bolts; a limiting sleeve 2 is fixedly connected to the bottom surface of the connecting frame 1, a probe rod 3 is arranged in the limiting sleeve 2, and an end of the probe rod 3 away from the limiting sleeve 2 is fixedly connected to a mounting sleeve 4, and a probe body 5 is arranged in the mounting sleeve 4; a connecting rod 9 is sealingly and slidably connected to the end of the limiting sleeve 2 away from the probe rod 3, and a fixing rod 8 is fixedly connected between the connecting rod 9 and the probe rod 3; a connecting sleeve 7 is fixedly connected in the limiting sleeve 2, and a push plate 10 that is sealingly and slidably connected to the side wall of the connecting rod 9 is fixedly connected to the inner wall of the limiting sleeve 2, and a driving mechanism for driving the push plate 10 to move is arranged on the connecting frame 1;

[0028] In the present application, the connecting frame 1 is installed on the wing by bolts. After installation, the probe rod 3 needs to be extended out of the wing. If the extended length of the probe rod 3 does not reach the preset distance, the push plate 10 can be driven to move by the driving mechanism. At this time, the push plate 10 will drive the connecting rod 9 to move, so that the connecting rod 9 drives the fixing rod 8 to push the probe rod 3 to adjust the position of the probe rod 3. After the probe rod 3 is adjusted to a suitable position, the push plate 10 is stopped from moving, thereby achieving the effect of adjusting the installation position of the probe rod 3. When the aircraft is flying, because the probe rod 3 is limited by the limit sleeve 2, the vibration of the probe rod 3 during flight can be greatly reduced.

[0029] The driving mechanism includes a hollow groove 11 provided in a connecting frame 1, a slider 12 is sealingly and slidably connected to the top surface of the hollow groove 11, a connecting pipe 13 is connected in the hollow groove 11, and the bottom end of the connecting pipe 13 extends into the connecting sleeve 7, a first spring is fixedly connected between the bottom surface of the slider 12 and the hollow inner wall, a second spring is fixedly connected between the end of the probe rod 3 close to the fixed rod 8 and the inner wall of the limit sleeve 2, and an electric telescopic rod 6 is provided on the connecting frame 1 provided with the hollow groove 11, and the output end of the electric telescopic rod 6 is used to push the slider 12;

[0030] When the probe rod 3 needs to be driven to move, the output end of the electric telescopic rod 6 can be used to push the slider 12, so that the slider 12 pushes the gas in the hollow groove 11 from the connecting pipe 13 into the connecting sleeve 7. At this time, the gas will push the push plate 10, so that the push plate 10 drives the connecting rod 9 to move, and then the fixed rod 8 pushes the probe rod 3 to move. When the probe rod 3 needs to move to the side close to the fixed rod 8, the output end of the electric telescopic rod 6 can be moved upward, so that the first spring pushes it to move upward, so that the push plate 10 can move to the side away from the probe rod 3. At this time, the second spring will also pull the probe rod 3, so that the probe rod 3 moves to the side close to the connecting rod 9, thereby achieving the effect of horizontal movement adjustment of the probe rod 3.

[0031] The connecting rod 9 is provided with a group of card slots 14, the limiting sleeve 2 is provided with an "L"-shaped slide slot 16, the vertical end of the slide slot 16 is slidably connected with a card block 15 engaged with the card slot 14, a third spring is fixedly connected between the top surface of the card block 15 and the inner wall of the slide slot 16, the horizontal end of the slide slot 16 is slidably connected with a magnetic block 18, a connecting line 17 is fixedly connected between the top surface of the card block 15 and the magnetic block 18, and a driving component for driving the magnetic block 18 to move is arranged in the connecting tube 13; when the probe rod 3 needs to be moved, the present application can be driven by the driving component. The driving assembly drives the magnetic block 18 to move, and the magnetic block 18 will pull the connecting wire 17, so that the connecting wire 17 drives the card block 15 to disengage from the card slot 14, and then the slider 12 moves downward to drive the probe rod 3 to move, and the probe rod 3 will drive the connecting rod 9 to move together. After the probe rod 3 moves to the appropriate position, the driving assembly is used to reset the magnetic block 18. At this time, the card block 15 will be engaged with the card slot 14 under the push of the third spring, thereby fixing the connecting rod 9, so as to further fix the probe rod 3 in the limit sleeve 2, thereby improving the fixing effect of the probe rod 3.

[0032] The driving assembly includes an elastic disk 20 that is sealed and slidably connected to the inner wall of the connecting tube 13, and a plurality of shrinkage holes are provided on the elastic disk 20. A group of elastic ropes 19 are fixedly connected to the top surface of the elastic disk 20, and the other end of the elastic rope 19 is fixedly connected to the inner wall of the connecting tube 13. A first magnetic sheet 21 that is magnetically attracted to the magnetic block 18 is fixedly connected to the elastic disk 20. When the slider 12 in the present application moves downward, the slider 12 will push the gas in the hollow groove 11 into the connecting tube 13. At this time, the gas will push the elastic disk 20. However, due to the resistance of the elastic rope 19 to the pulling of the elastic disk 20, the elastic disk 20 cannot continue to move after moving to a certain position. At this time, the shrinkage holes on the elastic disk 20 will be pushed into The first magnetic sheet 21 will be separated from the magnetic block 18, so that the third spring pushes the block 15 to engage with the slot 14, thereby achieving the effect of automatically driving the block 15 to engage with and disengage from the slot 14.

[0033] The probe body 5 is rotatably connected to the inner wall of the mounting sleeve 4, and one end of the mounting sleeve 4 is fixedly connected to a cleaning sleeve 32, and the inner wall of the cleaning sleeve 32 is fixedly connected to a group of bristles in contact with the probe body 5; after the probe body 5 in the present application is used for a long time, dust will inevitably accumulate on the end at which the probe body 5 transmits signals, which will affect the effect of signal transmission. The present application can rotate the probe body 5 so that the bristles on the inner wall of the mounting sleeve 4 clean the end at which the probe body 5 transmits signals, thereby improving the stability of the signal transmitted by the probe body 5.

[0034] The probe rod 3 is provided with a pair of air inlet holes 22 connected with the mounting sleeve 4, the side wall of the probe body 5 is provided with a group of driving grooves 26, and the probe rod 3 is provided with a sealing assembly; in the present application, when the probe body 5 needs to be cleaned, the sealing assembly can be used to make the probe rod 3 and the limiting sleeve 2 sealed, and then the slider 12 can be moved upward, and the second spring will pull the probe rod 3 at this time, so that the gas in the limiting sleeve 2 can be pushed by the probe rod 3, so that the gas enters the air inlet holes 22, and the driving groove 26 will be aligned with one of the air inlet holes 22. At this time, the gas will first be discharged from the air inlet hole 22 aligned with the driving groove 26, thereby pushing the driving groove 26 to drive the probe body 5 to rotate, so that the bristles can clean the probe body 5. During the rotation process, a driving groove 26 will pass through another driving groove 26, so that the probe body 5 can be driven to rotate continuously.

[0035] A hollow elastic ring 23 is fixedly connected to the side wall of the sealing assembly, a second magnetic plate 24 is fixedly connected to the inner wall of the elastic ring 23, and a magnetic ring 25 that is magnetically attracted to the second magnetic plate 24 is fixedly connected to the inner wall of the limiting sleeve 2. When gas needs to enter the air inlet 22, the elastic ring 23 on the probe rod 3 can be moved to the magnetic ring 25. At this time, the magnetic ring 25 will repel the second magnetic plate 24, so that the elastic ring 23 expands and fits the inner wall of the limiting sleeve 2. At this time, the probe rod 3 can be controlled to move to the side close to the fixed rod 8, so that the gas in the limiting sleeve 2 can enter the air inlet 22.

[0036] Embodiment 2: Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the outer wall of the limiting sleeve 2 is fixedly connected with an elastic hollow plate 27, a moving groove 28 is provided in the limiting sleeve 2, a round hole is provided between the hollow plate 27 and the moving groove 28, and a moving block 29 is sealed and slidably connected to the inner wall of the moving groove 28, and a starting mechanism for starting the electric telescopic rod 6 and moving the output end of the electric telescopic rod 6 upward is provided in the moving groove 28; when the probe rod 3 in the present application is flying in the air, if it encounters a strong airflow or the speed of the aircraft is too fast, the pressure on the probe rod 3 will increase, thereby causing The above mechanism of the probe rod 3 can make the hollow plate 27 first withstand the air pressure deformation, and let the gas in the hollow plate 27 enter the movable groove 28 from the round hole, thereby pushing the movable block 29 to move. If the hollow plate 27 is deformed to a certain extent, it means that the gas resistance is very large at this time, and the gas will push the movable block 29 to trigger the starting mechanism, so that the output end of the electric telescopic rod 6 moves upward. At this time, the slider 12 will move upward, so that the probe rod 3 moves into the limit sleeve 2, reducing the exposed part of the probe rod 3, thereby reducing the resistance and improving the safety of the probe rod 3 when in use.

[0037] The starting mechanism includes a second contact 31 fixedly connected to the inner wall of the moving groove 28, and the second contact 31 is fixedly connected to the side of the slider 12 close to the first contact 30. When the first contact 30 contacts the second contact 31, the electric telescopic rod 6 can be started to make the output end of the electric telescopic rod 6 move upward, and a fourth spring is fixedly connected between the side of the slider 12 away from the first contact 30 and the inner wall of the moving groove 28; when the hollow plate 27 in the present application is deformed to a certain extent, the gas in the hollow plate 27 will enter the moving groove 28 from the circular hole, and then push the moving groove 28, so that the first contact 30 contacts the second contact 31, thereby starting the electric telescopic rod 6, and making the output end of the electric telescopic rod 6 move upward, and at this time the slider 12 will move upward to allow the probe rod 3 to be received in the limit sleeve 2, so that the probe rod 3 can be automatically retracted into the limit sleeve 2 when encountering a large air resistance.

[0038] Working principle: In the present application, the connecting frame 1 is installed on the wing by bolts. After installation, the probe rod 3 needs to be extended out of the wing. If the extended length of the probe rod 3 does not reach the preset distance, the driving mechanism can be used to drive the push plate 10 to move. At this time, the push plate 10 will drive the connecting rod 9 to move, so that the connecting rod 9 drives the fixing rod 8 to push the probe rod 3 to adjust the position of the probe rod 3. After the probe rod 3 is adjusted to a suitable position, the push plate 10 is stopped from moving further, thereby achieving the effect of adjusting the installation position of the probe rod 3. When the aircraft is flying, because the probe rod 3 is limited by the limit sleeve 2, the vibration of the probe rod 3 during flight can be greatly reduced. In the present application, when it is necessary to drive the probe When the rod 3 moves, the slider 12 can be pushed by the output end of the electric telescopic rod 6, so that the slider 12 pushes the gas in the hollow groove 11 from the connecting pipe 13 into the connecting sleeve 7. At this time, the gas will push the push plate 10, so that the push plate 10 drives the connecting rod 9 to move, and then the fixed rod 8 pushes the probe rod 3 to move. When the probe rod 3 needs to move to the side close to the fixed rod 8, the output end of the electric telescopic rod 6 can be moved upward, so that the first spring pushes it to move upward, so that the push plate 10 can move to the side away from the probe rod 3. At this time, the second spring will also pull the probe rod 3, so that the probe rod 3 moves to the side close to the connecting rod 9, thereby achieving the effect of adjusting the horizontal movement of the probe rod 3;

[0039] When the probe rod 3 needs to move, the driving assembly can be used to drive the magnetic block 18 to move. At this time, the magnetic block 18 will pull the connecting line 17, so that the connecting line 17 drives the card block 15 to disengage from the card slot 14, and then the slider 12 is moved downward to drive the probe rod 3 to move. The probe rod 3 will drive the connecting rod 9 to move together. After the probe rod 3 moves to the appropriate position, the driving assembly is used to reset the magnetic block 18. At this time, the card block 15 will be engaged with the card slot 14 under the push of the third spring, thereby fixing the connecting rod 9, so as to further fix the probe rod 3 in the limit sleeve 2, thereby improving the fixing effect of the probe rod 3; when the slider 12 in the present application moves downward, the slider 12 will push the gas in the hollow groove 11 into the connecting pipe 13, and the gas will push the elastic disk 20 at this time, but because the elastic rope 19 has a resistance to the pulling of the elastic disk 20 The force is applied, and after the elastic disk 20 moves to a certain position, it cannot move further. At this time, the shrinkage hole on the elastic disk 20 will be opened under the push of the gas, so that the gas enters the limit sleeve 2 and pushes the push disk 10, so that the push disk 10 drives the probe rod 3 to move. When the elastic disk 20 is in a position where it cannot move, the first magnetic sheet 21 will move to the magnetic block 18, thereby attracting the magnetic block 18 to pull the card block 15 out of the card slot 14, so that the probe rod 3 can move normally. When the slider 12 stops moving downward, the elastic rope 19 will pull the elastic disk 20 to reset. During the resetting process, the shrinkage hole group is in a state of being stretched open by the gas. During the resetting process, the first magnetic sheet 21 will be separated from the magnetic block 18, so that the third spring pushes the card block 15 to engage with the card slot 14. The above mechanism achieves the effect of automatically driving the card block 15 to engage and disengage with the card slot 14.

[0040] After the probe body 5 in the present application is used for a long time, dust will inevitably accumulate on the end of the probe body 5 that transmits the signal, which will affect the effect of the signal transmission. The present application can rotate the probe body 5 so that the bristles on the inner wall of the mounting sleeve 4 can clean the end of the probe body 5 that transmits the signal, thereby improving the stability of the signal transmitted by the probe body 5; in the present application, when it is necessary to clean the probe body 5, the sealing component can be used to make the probe rod 3 and the limit sleeve 2 sealed, and then the slider 12 can be moved upward at this time. At this time, the second spring will pull the probe rod 3, so that the gas in the limit sleeve 2 can be pushed by the probe rod 3, so that the gas enters the air inlet 22, and the driving groove 26 will move to one of the air inlet holes. 22 is aligned, at this time, the gas will first be discharged from the air inlet 22 aligned with the driving groove 26, thereby pushing the driving groove 26 to drive the probe body 5 to rotate, so that the bristles can clean the probe body 5. During the rotation process, one driving groove 26 will pass through another driving groove 26, so that the probe body 5 can be driven to rotate continuously; when the gas needs to enter the air inlet 22, the application can move the elastic ring 23 on the probe rod 3 to the magnetic ring 25, at this time the magnetic ring 25 will repel the second magnetic sheet 24, so that the elastic ring 23 expands and fits the inner wall of the limiting sleeve 2, and the probe rod 3 can be controlled to move to the side close to the fixed rod 8, so that the gas in the limiting sleeve 2 can enter the air inlet 22.
