[0028] In the embodiment of the present invention, when in use, the base 1 is glued to the inspection drone with glue, the locator 3 is placed on the base 1, the vertical guide groove 6 on the sealing cover 2 is inserted into the vertical guide protrusion 5, and the pressure plate 7 presses the locator 3 through the elastic force of the compression spring 8. When the inspection drone crashes accidentally, the compression spring 8 acts as a buffer for the locator 3, and the side wall limit mechanism limits the locator 3 from shaking in the sealing cover 2. Then the sealing cover 2 is rotated, and the sealing cover 2 drives the rotating seat 4 to rotate through the vertical guide groove 6 and the guide protrusion 5. When the sealing cover 2 is rotated, the locking mechanism fixes the sealing cover 2 on the base 1, thereby completing the installation of the locator 3, and then quickly installing the locator 3.

[0029] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, a supplementary ring 11 is slidably connected to the rotating seat 4, a guide notch 13 is provided on the inner wall of the supplementary ring 11, the guide notch 13 is slidably connected to the vertical guide protrusion 5, a compression spring 12 is fixed to the lower end of the supplementary ring 11, and the end of the compression spring 12 is fixed to the rotating seat 4.

[0030] In the embodiment of the present invention, when the sealing cover 2 and the positioner 3 are not installed, the compression spring 12 pushes the supplementary ring 11 upward so that the upper end of the supplementary ring 11 is flush with the upper end of the base 1, thereby making the surface of the base 1 smooth and reducing wind resistance.

[0031] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the locking mechanism includes a horizontal slide groove 14 arranged in the base 1, a horizontal slider 15 is slidably connected in the horizontal slide groove 14, and a magnet 29 is fixed to the upper end of the horizontal slider 15; an insertion rod 16 is fixed to one end of the horizontal slider 15 close to the sealing cover 2, and a socket 17 cooperating with the insertion rod 16 is arranged on the side wall of the sealing cover 2, and a transmission component is arranged on the base 1, and when the rotating seat 4 rotates, the transmission component drives the insertion rod 16 to be inserted into the socket 17; the transmission component one includes a wire groove 18 arranged in the base 1, and an elastic connecting rope 19 is arranged in the wire groove 18, and a compression spring three 20 is fixed to the other end of the horizontal slider 15, and the compression spring three 20 is arranged in the horizontal slide groove 14; an avoidance groove 28 is arranged at the lower end of the horizontal slider 15, one end of the elastic connecting rope 19 is fixed in the avoidance groove 28, and the other end of the elastic connecting rope 19 is fixed on the side wall of the rotating seat 4.

As the sealing cover 2 rotates, when the insertion rod 16 coincides with the insertion hole 17, the insertion rod 16 is inserted into the insertion hole 17, thereby fixing the base 1 and the sealing cover 2 in a fixed connection, thereby limiting the rotation of the sealing cover 2 and sealing. The cover 2 rotates in the opposite direction, and the elastic force of the elastic connecting rope 19 is not released. When the positioner 3 needs to be replaced, the magnet 29 is attracted by an electromagnet or a permanent magnet and driven to move.

A vertical wedge block 22 is slidably connected in the movable groove 21; one end of the horizontal guide block 10 is provided with a slope 23 that cooperates with the vertical wedge block 22, and the other end of the horizontal guide block 10 is connected with a compression spring four 24, and the compression spring four 24 is arranged in the horizontal guide groove 9; a contraction slide groove 25 is provided on the horizontal guide block 10, and a clamping block 26 is slidably connected in the contraction slide groove 25, and a compression spring five 27 is fixedly connected to one side of the clamping block 26, and the end of the compression spring five 27 is fixed in the contraction slide groove 25.

[0034] In the embodiment of the present invention, when the sealing cover 2 is buckled on the base 1, the vertical wedge 22 first contacts the upper end of the base 1, and as the sealing cover 2 moves downward, the vertical wedge 22 moves upward relative to the sealing cover 2, and the vertical wedge 22 pushes the horizontal guide block 10 through the inclined surface 23, thereby enabling the horizontal guide block 10 to overcome the elastic force of the compression spring four 24 and drive it to move toward the sealing cover 2, and the horizontal guide block 10 drives the clamping block 26 to press against the side wall of the sealing cover 2, thereby limiting the shaking of the positioner 3 in the sealing cover 2. At the same time, when the patrol drone accidentally crashes, the compression spring five 27 can play a buffering role for the positioner 3.

When the patrol drone crashes accidentally, the compression spring 8 plays a buffering role for the locator 3. When the sealing cover 2 is buckled on the base 1, the vertical wedge 22 first contacts the upper end of the base 1, and as the sealing cover 2 is buckled on the base 1, the vertical wedge 22 contacts the upper end of the base 1. The sealing cover 2 moves downward, and the vertical wedge block 22 moves upward relative to the sealing cover 2. The vertical wedge block 22 pushes the horizontal guide block 10 through the inclined surface 23, so that the horizontal guide block 10 overcomes the elastic force of the compression spring 24 and drives it to move toward the sealing cover 2. The horizontal guide block 10 drives the clamping block 26 to press against the side wall of the sealing cover 2, thereby limiting the locator 3 from shaking in the sealing cover 2. At the same time, when the patrol drone crashes accidentally, the compression spring 5 27 can buffer the locator 3, and the sealing cover 2 passes through the vertical guide groove 6. The guide protrusion 5 drives the rotating seat 4 to rotate, and the rotating rotating seat 4 pulls the elastic connecting rope 19, the elastic connecting rope 19 is stretched, and the elastic connecting rope 19 overcomes the elastic force of the compression spring 3 20 and pulls the horizontal slider 15, and the horizontal slider 15 drives the insertion rod 16 to abut against the side wall of the sealing cover 2. As the sealing cover 2 rotates, when the insertion rod 16 coincides with the insertion hole 17, the insertion rod 16 is inserted into the insertion hole 17, thereby fixing the base 1 and the sealing cover 2 to be connected, thereby limiting the rotation of the sealing cover 2. When the positioner 3 needs to be replaced When the sealing cover 2 is removed, the electromagnet or permanent magnet attracts the magnet 29 and drives the magnet 29 to move. The magnet 29 overcomes the elastic force of the elastic connecting rope 19 and drives the horizontal slider 15 away from the sealing cover 2. The horizontal slider 15 drives the insertion rod 16 away from the sealing cover 2, so that the insertion rod 16 is separated from the insertion hole 17. The rotation restriction of the sealing cover 2 is released, and the elastic connecting rope 19 pulls the rotating seat 4 to flip and reset. At this time, the sealing cover 2 can be removed, and the compression spring 12 can also push the supplementary ring 11 upward, and the supplementary ring 11 drives the sealing cover 2 to move upward.
