Usually, maps and traffic and tourism maps we see are completed on the basis of surveying and mapping, with the shape, size and gravity field of the earth and other planets as the research objects. The objects of research and mapping are very extensive, mainly including various landforms and landforms on the surface and underground geological structures, hydrology, mineral deposits, etc., such as mountains, rivers, houses, roads, vegetation, etc. Since surveying and mapping work often needs to be carried out in complex terrain, such as swamps and other terrains, and existing surveying and mapping equipment is usually supported by a tripod, and the bottom legs of the tripod are usually sharp, and the sharp legs cannot be retracted when the device is not in use. Therefore, when the surveying and mapping equipment is supported by a tripod to perform surveying and mapping operations in swamps with soft geology, it is not convenient to stably support the surveying and mapping equipment for surveying and mapping operations in complex swamps, and it is also impossible to avoid sharp legs from hurting people when the device is carried. Therefore, in view of the above problems, a surveying and mapping equipment suitable for complex terrain surveying and mapping is proposed. Utility Model Content

When the positioning pin 5 is corroded and damaged, the positioning pin 5 is disconnected from the slider 4 by rotating, which facilitates the replacement of the positioning pin 5 when it is corroded and damaged.

[0022] Example 3

[0023] like Figure 1-2As shown, in order to solve the problem that it is inconvenient to control the fixed plate 9 to drive the airbag 11 to rotate downward, the top end of the outer side of the threaded shaft 3 is fixedly connected to a worm wheel 6, and the outer side of the worm wheel 6 is meshed with a worm 7, and the worm 7 runs through the support rod 2. The worm 7 is rotatably connected to the support rod 2, and the worm 7 is engaged with the worm wheel 6 by rotating the worm 7 to further control the spiral connection between the threaded shaft 3 and the slider 4, which facilitates the airbag 11 on the outer side of the fixed plate 9 to rotate downward by rotating the rod 8.

[0024] Example 4

[0025] like Figure 1-2 As shown, in order to solve the problem that it is inconvenient to fold up the airbag 11 when the device is finished using, one end of the fixed plate 9 is rotatably connected to the fixed rod 10 through a rotating shaft, and the fixed rod 10 is fixedly connected to the support rod 2. The fixed plate 9 and the airbag 11 rotate at one time at an angle of 90°. When the device is finished using, the fixed plate 9 is controlled by reversing the worm gear 7 to drive the airbag 11 to rotate upward 90°, which facilitates the folding of the airbag 11 when the device is finished using.

[0026] Example 5

[0027] like Figure 1-2 As shown, in order to solve the problem that it is inconvenient to replace the airbag 11 when it is damaged, a fixing block 12 is fixedly connected to the top of the airbag 11, and the fixing block 12 is slidably connected to the fixing plate 9, a clamping rod 13 is slidably connected to the inner side of the fixing block 12, and the clamping rod 13 passes through the fixing block 12 and the fixing plate 9, the clamping rod 13 is slidably connected to the fixing plate 9, a slide plate 14 is fixedly connected to one end of the outer side of the clamping rod 13, and the slide plate 14 is slidably connected to the fixing plate 9, a spring 15 is provided at the other end of the outer side of the clamping rod 13, and the spring 15 is fixedly connected to the slide plate 14 and the fixing plate 9, the clamping rod 13 is pulled to compress the spring 15, and at the same time the clamping rod 13 is out of contact with the fixing block 12 at the top of the airbag 11, which facilitates the replacement of the airbag 11 when it is damaged.

At this time, the worm wheel 6 drives the threaded shaft 3 to be spirally connected with the slider 4. The slider 4 drives the positioning nail 5 to slide downward from the support rod 2. At the same time, the slider 4 also drives the fixing plate 9 to drive the airbag 11 to turn downward through the rotating rod 8. After completing the above operations, the positioning nail 5 is inserted into the swamp to make the airbag 11 contact with the ground. At this time, the airbag 11 has a certain buoyancy and the airbag 11 has a large contact area with the ground. The characteristics of the ground can be used to stably pass through the support rod 2. The support surveying and mapping equipment 1 performs surveying and mapping operations in a swamp with soft geology. When the device is not in use, the positioning pin 5 is reset to the support rod 2 by reversing the worm gear 7, so as to avoid the positioning pin 5 from injuring people during the carrying of the device. During the carrying and use of the device, when the airbag 11 is damaged during the carrying and use of the device, the slide plate 14 is pulled to compress the spring 15, and at the same time, the positioning pin 13 is disengaged from the fixing block 12 on the top of the airbag 11, and the damaged airbag 11 can be removed for replacement, thereby ensuring the normal use of the device in complex swamp terrain.
