The auxiliary device 2 is used to increase the contact area between the roller of the roller ruler body 1 and the ground and reduce the depth of the sinking;

[0030] The auxiliary device 2 includes a connecting flange plate 201, which is fixedly connected to the side of the roller hub of the roller ruler body 1, and the side of the connecting flange plate 201 is fixedly connected with a supporting surface 204, the bottom of the supporting surface 204 is horizontal with the bottom of the roller of the roller ruler body 1, and the width of the supporting surface 204 is greater than the width of the roller of the roller ruler body 1;

[0031] The connecting flange plate 201 and the roller hub of the roller ruler body 1 are installed in a detachable manner;

[0032] The support surface 204 is in a circular ring or cylindrical shape to increase the contact area. The support surface 204 is made of a thin rigid material, which can reduce the weight of the device and avoid deformation.

[0033] Through the above technical solution, a connecting flange plate 201 is installed on the side of the roller hub of the roller ruler body 1, and a supporting surface 204 is extended through the edge of the connecting flange plate 201, so that the width of the roller of the roller ruler body 1 is increased through the supporting surface 204, and the contact area with the ground is improved, so that it can float on the ground in silt and soft terrain and will not sink easily, thereby achieving the effect of being able to carry out surveying and mapping in silt and soft terrain.

[0034] Specifically, a limiting hole 101 and a threaded hole 102 are provided on the side of the roller hub of the roller ruler body 1, and a limiting column 202 is fixedly connected to the side of the connecting flange plate 201 and a through hole 203 is provided. The limiting column 202 is inserted into the inside of the limiting hole 101, and the position of the limiting column 202 is adapted to the position of the threaded hole 102 and is fixed by a bolt 3.

[0035] Through the above technical solution, a limiting hole 101 and a threaded hole 102 are opened on the side of the roller hub of the roller ruler body 1, and a limiting column 202 and a through hole 203 are set on the side of the connecting flange plate 201. The limiting column 202 and the limiting hole 101 cooperate to limit the connecting flange plate 201, and the bolt 3 passes through the through hole 203 and is threadedly connected to the threaded hole 102 to fix the connecting flange plate 201, thereby achieving the effect of convenient disassembly and assembly of the connecting flange plate 201, so that the roller ruler body 1 can conveniently replace the auxiliary device 2 that adapts to the terrain according to the requirements of the terrain.

[0036] Specifically, the number of the limiting holes 101 is two or more, and the number of the threaded hole 102 is one.

[0037] Through the above technical solution, providing two or more limiting holes 101 can improve the constraint ability on the connecting flange plate 201, and providing one threaded hole 102 can improve the convenience of installation.

[0039] Through the above technical solution, the purpose of setting the inner convex ring 2041 and the cavity 2042 is to enhance the buoyancy of the support surface 204. When the inner wall of the support surface 204 sinks slightly into the mud or soft soil, the buoyancy provided by the cavity 2042 can prevent the support surface 204 from sinking urgently. Specific implementation method 2

[0041] A land surveying and mapping improvement device adapted to multiple terrains under this specific implementation method, such as Figure 5 As shown, it includes a roller ruler body 1, and an auxiliary device 2 is installed on the side of the roller hub of the roller ruler body 1. The auxiliary device 2 is used to increase the contact area between the roller of the roller ruler body 1 and the ground and reduce the depth of the sinking;

[0042] The auxiliary device 2 includes a connecting flange plate 201, which is fixedly connected to the side of the roller hub of the roller ruler body 1, and the side of the connecting flange plate 201 is fixedly connected with a supporting surface 204, the bottom of the supporting surface 204 is horizontal with the bottom of the roller of the roller ruler body 1, and the width of the supporting surface 204 is greater than the width of the roller of the roller ruler body 1;

[0043] The connecting flange plate 201 and the roller hub of the roller ruler body 1 are installed in a detachable manner;

[0044] The supporting surface 204 is a metal sheet, and the supporting surface 204 is obliquely arranged on the side of the connecting flange plate 201 .

[0045] Through the above technical solution, the supporting surface 204 is set to an inclined metal sheet, so that when surveying the water area, the roller ruler body 1 is driven to move on the water area by using a water surface carrier. When the supporting surface 204 contacts the water surface, the thrust generated during the movement will push the supporting surface 204 to rotate the roller of the roller ruler body 1, thereby achieving the effect of surveying the water area.

[0046] Specifically, a limiting hole 101 and a threaded hole 102 are provided on the side of the roller hub of the roller ruler body 1, and a limiting column 202 is fixedly connected to the side of the connecting flange plate 201 and a through hole 203 is provided. The limiting column 202 is inserted into the inside of the limiting hole 101, and the position of the limiting column 202 is adapted to the position of the threaded hole 102 and is fixed by a bolt 3.

[0047] Through the above technical solution, a limiting hole 101 and a threaded hole 102 are opened on the side of the roller hub of the roller ruler body 1, and a limiting column 202 and a through hole 203 are set on the side of the connecting flange plate 201. The limiting column 202 and the limiting hole 101 cooperate to limit the connecting flange plate 201, and the bolt 3 passes through the through hole 203 and is threadedly connected to the threaded hole 102 to fix the connecting flange plate 201, thereby achieving the effect of convenient disassembly and assembly of the connecting flange plate 201, so that the roller ruler body 1 can conveniently replace the auxiliary device 2 that adapts to the terrain according to the requirements of the terrain.

[0048] Specifically, the number of the limiting holes 101 is two or more, and the number of the threaded hole 102 is one.

[0049] Through the above technical solution, providing two or more limiting holes 101 can improve the constraint ability on the connecting flange plate 201, and providing one threaded hole 102 can improve the convenience of installation.

[0050] Specifically, the support surface 204 is arc-shaped, and the support surfaces 204 are distributed in an equidistant circular array.

[0051] Through the above technical solution, the support surface 204 is arranged in an arc shape, so as to increase the pushing ability of the water flow on the support surface 204, and the purpose of providing multiple support surfaces 204 is to enable the support surface 204 to be evenly pushed by the water flow.

[0052] When in use, a connecting flange plate 201 is installed on the side of the roller hub of the roller ruler body 1, and a supporting surface 204 is extended through the edge of the connecting flange plate 201, so that the width of the roller of the roller ruler body 1 is increased through the supporting surface 204, and the contact area with the ground is increased, so that it can float on the ground in silt and soft terrain and will not sink easily, achieving the effect of being able to carry out mapping in silt and soft terrain;

[0053] By setting the support surface 204 as an inclined metal sheet, when surveying water areas, the roller ruler body 1 can be driven to move on the water area by using a water surface carrier. When the support surface 204 contacts the water surface, the thrust generated during the movement will push the support surface 204 to rotate the roller of the roller ruler body 1, thereby achieving the effect of surveying the water area.
