[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-3As shown, a fixing device for an aerial geophysical magnetometer includes a protective box 1, the bottom end of the protective box 1 is symmetrically rotatably connected with a door panel 4, the bottom of the inner side of the protective box 1 is provided with a switch door structure 3 for opening and closing the two door panels 4, the top of the protective box 1 is provided with a lifting platform 2 for driving the switch door structure 3 to rise and fall, the lifting platform 2 includes a screw rod 21 and a carrier plate 22, the screw rod 21 is rotatably connected to the screw rod 21 at the top of the protective box 1, and moving blocks 23 are symmetrically arranged on the screw rod 21, both ends of the moving blocks 23 are fixedly connected with an extension plate 24, one end of the extension plate 24 is rotatably connected with a first connecting rod 25, the four first connecting rods 25 are respectively rotatably connected to the four corners of the carrier plate 22, the middle part of the carrier plate 22 is fixedly connected with a mounting column 26, and the switch door structure 3 is arranged on the mounting column 26.

[0020] According to the above structure, the aeromagnetometer is installed at the bottom end of the mounting column 26 during use. The screw rod 21 is rotated clockwise during use to make the two moving blocks 23 approach each other, thereby causing the carrier plate 22 to descend. The carrier plate 22 descends, driving the switch door structure 3 to descend, causing the two door panels 4 to be pushed open, and the mounting column 26 descends and extends from the opened bottom end of the protective box 1 for detection.

[0021] like Figure 1 and 3 As shown, the side wall of the screw 21 is symmetrically provided with threaded portions with opposite spiral directions, and the two moving blocks 23 are respectively threadedly connected to the two threaded portions. The top of the protection box 1 is fixedly connected with a forward and reverse motor 27, and the output shaft of the forward and reverse motor 27 is fixedly connected to one end of the screw 21.

[0022] According to the above structure, when the screw 21 is driven to rotate, the forward and reverse motor 27 drives the screw 21 to rotate. When the screw 21 rotates clockwise, the two moving blocks 23 approach each other. When the screw 21 rotates counterclockwise, the two moving blocks 23 move away from each other, and the carrier plate 22 rises.

[0023] like Figure 2 and 3 As shown, the switch door structure 3 includes a slide cylinder 31 slidably connected to the side wall of the mounting column 26, the top end of the slide cylinder 31 is fixedly connected to a driving plate 33, the side wall of the mounting column 26 is fixedly connected to a supporting ring 32, the side wall of the mounting column 26 is sleeved with a top spring 34, the top spring 34 is squeezed and arranged between the carrier plate 22 and the driving plate 33, the two ends of the top spring 34 are respectively fixedly connected to the top end of the driving plate 33 and the bottom end of the carrier plate 22, the slide cylinder 31 and the driving plate 33 are an integrated structure, the four corners of the driving plate 33 are rotatably connected to the second connecting rod 35, and one end of the second connecting rod 35 is rotatably connected to the middle part of the top end of the corresponding door panel 4.

[0024] According to the above structure, when the carrier plate 22 descends, the mounting column 26 descends, and the top spring 34 presses the driving plate 33 downward, so that the four second connecting rods 35 push the two door panels 4 to open. After the mounting column 26 descends, the aeronautical magnetometer installed at the bottom of the mounting column 26 extends out. When the door panel 4 rotates to a vertical state, the mounting column 26 continues to descend. At this time, the top spring 34 is compressed, and the aeronautical magnetometer continues to descend one end distance to avoid being blocked. When retracting, the screw 21 is driven to rotate counterclockwise by the forward and reverse motors 27, so that The two moving blocks 23 are moved away from each other, so that the carrier plate 22 rises, and the aeronautical magnetometer at the bottom of the mounting column 26 rises immediately. Under the push of the top spring 34, the driving plate 33 stops at one end distance first. At this time, the door panel 4 is in an open state. When the support ring 32 contacts the bottom end of the slide cylinder 31, the slide cylinder 31 is pulled upward. At this time, the door panel 4 is closed upward to prevent the door panel 4 from closing too early and causing the aeronautical magnetometer to be unable to retract. After the aeronautical magnetometer retracts, it is protected by the protection box 1 to prevent the aeronautical magnetometer from being damaged during take-off and landing.

[0025] The working principle of the utility model is as follows: when in use, the aeromagnetic meter is installed at the bottom end of the mounting column 26, and the forward and reverse motors 27 drive the screw rod 21 to rotate clockwise, so that the two moving blocks 23 are close to each other, so that the carrier plate 22 is lowered, and when the carrier plate 22 is lowered, the mounting column 26 is lowered, and the top spring 34 presses the driving plate 33 to lower, so that the four second connecting rods 35 push the two door panels 4 to open, and after the mounting column 26 is lowered, the aeromagnetic meter installed at the bottom end of the mounting column 26 extends out, and when the door panel 4 rotates to a vertical state, the mounting column 26 continues to descend, and at this time the top spring 34 is compressed, and the aeromagnetic meter continues to descend a distance to avoid When the aeronautical magnetometer is blocked and folded, the forward and reverse motors 27 drive the screw 21 to rotate counterclockwise, so that the two moving blocks 23 move away from each other, the carrier plate 22 rises, and the aeronautical magnetometer at the bottom of the mounting column 26 rises immediately. Under the push of the top spring 34, the driving plate 33 stops at one end distance first. At this time, the door panel 4 is in an open state. When the support ring 32 contacts the bottom end of the slide cylinder 31, the slide cylinder 31 is pulled upward. At this time, the door panel 4 is closed upward to prevent the door panel 4 from closing too early and causing the aeronautical magnetometer to be unable to retract. After the aeronautical magnetometer retracts, it is protected by the protection box 1 to prevent the aeronautical magnetometer from being damaged during take-off and landing.

[0026] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
