It should be further explained that, in the process of the flight of the unmanned aerial vehicle body 1, the lower surface of the extension plate 1101 is mutually attached to the lower surface of the linkage plate 10, and then when the unmanned aerial vehicle body 1 lands, because the linkage plate 10, the jacking rod 7011 and the second buffer rod 701 move synchronously, after the second buffer rod 701 rises for a certain distance, the linkage plate 10 is blocked by the extension plate 1101 and cannot continue to rise, so that the second buffer rod 701 and the jacking rod 7011 also stop rising, but the first buffer rod 7 still continues rising at this moment, so that the unmanned aerial vehicle body 1 can be skewed at this moment, but the skew degree is smaller, can be ignored, the center of gravity of the unmanned aerial vehicle body 1 cannot be deviated, and the unmanned aerial vehicle body 1 can still stably land.
According to the structure, when the linkage cover plate 3 rotates, the extrusion block 303 rotates along with the linkage cover plate 3, the cambered end of the driven plate 11 is extruded in the rotation process of the extrusion block 303, the cambered end of the driven plate 11 is stressed and then moves transversely towards the inside of the U-shaped groove 1021, the whole driven plate 11 moves transversely towards the inside of the U-shaped groove 1021, the return spring 1022 is extruded in the transverse moving process of the driven plate 11, the return spring 1022 contracts and stores power, the driven plate 11 drives the extension plate 1101 to move transversely along the inside of the sliding groove 1023, the extension plate 1101 is initially positioned on the upper surface of the linkage plate 10, so that the extension plate 1101 slides along the upper surface of the linkage plate 10, finally, after the linkage cover plate 3 and the surveying instrument body 2 are parallel to each other, the extrusion block 303 just contacts the lowest part of the cambered end of the driven plate 11, the driven plate 11 does not move transversely any more at the moment, and the extension plate 1101 just moves away from the upper part of the linkage plate 10 at the moment, and then the external restriction of linkage board 10 is just relieved, and second buffer pole 701 and jacking rod 7011 alright continue to rise this moment, and linkage board 10 rises under the effect of jacking rod 7011, and then the synchronous rising of connecting rod 1001, and connecting rod 1001 drives sealed piece 1002 and rises, and sealed piece 1002 block is gone up to the breach of linkage apron 3 finally to this makes surveying and mapping probe 201 sealed totally.
As shown in fig. 7, two fixed frames 6 are symmetrically and fixedly connected to the upper surface of the supporting plate 102, one side of each of the two fixed frames 6 opposite to the other side of the surveying instrument body 2 is fixedly connected to both sides of the surveying instrument body 2, a cavity 601 is formed inside each of the two fixed frames 6, the cavity 601 is arranged outside the transmission mechanism, the cavity 601 is used for protecting the transmission mechanism, and the transmission mechanism can be protected from being influenced by external factors during operation through the protection of the cavity 601.
As shown in fig. 7 and 8, each of the transmission mechanisms includes a transmission rack 702, a linkage gear 603, and a linkage rotating rod 602, the transmission rack 702 is fixedly connected to the top end of the first buffer rod 7, the linkage gear 603 is disposed above the support plate 102, the linkage gear 603 is engaged with the transmission rack 702, the linkage rotating rod 602 is fixedly sleeved at the axis of the linkage gear 603, the transmission rack 702 penetrates through the fixed frame 6, and the top end and the middle portion of the transmission rack 702 are both fixedly sleeved with a stopper 7021, therefore, the stroke of the transmission rack 702 is limited, the rotation angle of the linkage gear 603 is limited, one end of the linkage rotating rod 602 is rotatably connected with the inner wall of the cavity 601 through a bearing, the other end of the linkage rotating rod 602 is fixedly connected with one side of the connecting plate 302, the linkage rotating rod 602 rotates under the transmission action of the transmission rack 702 and the linkage gear 603, and the linkage rotating rod 602 drives the connecting plate 302 to rotate to realize the rotation of the sealing mechanism.
According to above-mentioned structure, when unmanned aerial vehicle body 1 descends, first buffer lever 7 contact ground rises, first buffer lever 7 drives transmission rack 702 and rises, meshing linkage gear 603 when transmission rack 702 rises, linkage gear 603 drives linkage bull stick 602 rotatory, linkage bull stick 602 drives connecting plate 302 and rotates, connecting plate 302 drives linkage apron 3 rotation through extrusion movable rod 301 to this makes linkage apron 3 can rotate gradually to surveying instrument body 2's front.
A surveying and mapping method of a surveying and mapping device based on an unmanned aerial vehicle comprises the following steps:
step 1: the unmanned aerial vehicle body 1 carries the surveying instrument body 2 to rise synchronously, and then the balancing weight 8 descends gradually under the action of self gravity, so that the damping mechanism is driven to descend under stress;
step 2: the damping mechanism descends and simultaneously drives the transmission rack 702 to descend, the transmission rack 702 drives the transmission mechanism to operate, the transmission mechanism drives the sealing mechanism to rotate, and finally the linkage cover plate 3 is rotated away from the front side of the surveying instrument body 2;
and step 3: unmanned aerial vehicle body 1 rises to and tends to balanced behind the required height, then surveying and mapping appearance body 2 alright survey and drawing its region that openly faces.
The working process and the beneficial effects of the invention are as follows: after 1 work of unmanned aerial vehicle body is accomplished and the in-process that falls to the ground, unmanned aerial vehicle body 1 at first can accept damper's cushioning effect, make unmanned aerial vehicle body 1 bear the reaction force that comes from ground and reduce, make unmanned aerial vehicle body 1 can not excessively vibrate, damper's absorbing while can provide power for drive mechanism again, make this drive mechanism operation and drive sealing mechanism rotatory, and then sealing mechanism gets up unmanned aerial vehicle body 1's front protection.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the design concept of the present invention should be included in the scope of the present invention.
