[0029] Example 1

[0030] like Figure 1-4 As shown, a surveying device for building planning includes an upper support plate 1 for placing surveying instruments, a middle support plate 4 is arranged below the upper support plate 1, a plurality of connecting rods 2 are arranged between the edge of the upper support plate 1 and the edge of the middle support plate 4, the upper ends of the connecting rods 2 are fixedly connected to the upper support plate 1, and the lower ends of the connecting rods 2 are fixedly connected to the middle support plate 4, and a balance adjustment mechanism is installed on the middle support plate 4.

Threaded holes can be provided on the surveying instrument and the upper support plate 1 , and the surveying instrument and the upper support plate 1 are connected by screws, thereby fixing the surveying instrument on the upper support plate 1 .

[0032] Example 2

[0033] like Figure 1-4 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that the balance adjustment mechanism includes a spherical and transparent shell 3, the bottom of the shell 3 is detachably connected to the top surface of the middle support plate 4, a float 9 is arranged in the shell 3, and the shell 3 is filled with water.

[0034] The balance adjustment mechanism also includes a plurality of guide grooves 17, which are provided on the middle support plate 4 and are arranged in a circular array around the center of the middle support plate 4. The balance adjustment mechanism also includes a guide column 16, which is located in the guide groove 17, and a fixed elastic band 18 is provided on the guide column 16, and the edge of the elastic band 18 is fixedly connected to the inner wall of the guide groove 17, and two limit rings 19 are provided on the guide column 16, and the limit rings 19 are fixedly connected to the guide column 16, and the two limit rings 19 are respectively located on the upper and lower sides of the middle support plate 4, and a first adjustment rod 13 is provided through the guide column 16, and the first adjustment rod 13 is slidably connected to the guide column 16, and a limit block 14 is provided above the guide column 16, and the limit block 14 is fixedly connected to the first adjustment rod 13, and a buffer spring 15 is provided between the limit block 14 and the guide column 16, and the buffer spring 15 is sleeved on the first adjustment rod 13, and the upper end of the buffer spring 15 is fixedly connected to the limit block 14, and the lower end of the buffer spring 15 is fixedly connected to the guide column 16. The balance adjustment mechanism also includes a mounting seat 11, a mounting seat 11 is arranged above the first adjustment rod 13, the top of the first adjustment rod 13 is fixedly connected to the mounting seat 11, a ball 10 is movably embedded in the top of the mounting seat 11, and the ball 10 is against the inner wall of the shell 3. The balance adjustment mechanism also includes a plurality of second adjustment rods 20, which are arranged in a circular array around the center of the middle support plate 4, the lower end of the first adjustment rod 13 extends to the bottom of the middle support plate 4, the lower end of the first adjustment rod 13 is fixedly connected to one end of the second adjustment rod 20, and the other end of the second adjustment rod 20 is fixedly connected to the support column 22, a silicone sheet 21 is fixedly arranged on the top of the support column 22, and the silicone sheet 21 is against the bottom surface of the middle support plate 4, and a plurality of water seepage holes 12 are opened on the middle support plate 4, and the water seepage holes 12 are located above the silicone sheet 21. The balance adjustment mechanism also includes a plurality of water storage barrels 6, the water storage barrels 6 are located below the support column 22, and the top of the water storage barrels 6 is fixedly connected to the middle support plate 4 through the bracket 23. A lower support plate 7 is provided below the water storage barrel 6, and the bottom of the water storage barrel 6 is fixedly connected to the lower support plate 7. A plurality of support rods 5 are provided below the lower support plate 7, and the tops of the support rods 5 are connected to the lower support plate 7 through hinges 24.

[0035] When surveying muddy ground or wetland, rotate the support rod 5 to adjust the upper support plate 1 and the middle support plate 4 to a roughly horizontal position. At this time, the upper support plate 1 and the middle support plate 4 are still slightly tilted. Taking the clockwise tilt of the upper support plate 1 and the middle support plate 4 as an example, since there is water in the outer shell 3, the float 9 will move to the left side of the upper support plate 1 and the middle support plate 4 under the action of buoyancy. When the float 9 moves to the left side of the upper support plate 1 and the middle support plate 4, it will push the first adjustment rod 13 on the left side to move left. When the first adjustment rod 13 moves to the left, it drives the guide column 16 to move synchronously along the guide groove 17. At the same time, the ball 10 on the top of the first adjustment rod 13 slides to the left along the spherical inner wall of the outer shell 3, causing the first adjustment rod 13 to move down and compress the buffer spring 15.

[0036] During the downward movement of the first adjusting rod 13, the second adjusting rod 20 and the supporting column 22 drive the silicone sheet 21 to move downward synchronously, so that the silicone sheet 21 no longer blocks the water seepage hole 12 on the left, and the water in the outer shell 3 slowly seeps into the water storage barrel 6 on the left through the water seepage hole 12 on the left, thereby increasing the amount of water in the water storage barrel 6 on the left and making it heavier, so that the water storage barrel 6 on the left drives the device to tilt counterclockwise, and the upper support plate 1 and the middle support plate 4 that were originally tilted clockwise slowly return to the normal position.

[0037] When the upper support plate 1 and the middle support plate 4 are horizontal, the float 9 returns to the center of the middle support plate 4 and no longer pushes any first adjusting rod 13. Under the elastic force of the buffer spring 15, the ball 10 moves to the right along the inner wall of the shell 3 and resets, and the first adjusting rod 13 moves to the right and resets synchronously. When the first adjusting rod 13 moves to the right, it moves upward synchronously. The first adjusting rod 13 drives the silicone sheet 21 to move upward synchronously through the second adjusting rod 20 and the support column 22, so that the silicone sheet 21 blocks the water seepage hole 12 again, so that the water in the shell 3 no longer flows out through the water seepage hole 12.

[0038] By observing whether water flows out of the seepage hole 12, it can be determined whether the upper support plate 1 and the middle support plate 4 are level, thereby determining whether the surveying and mapping instrument on the upper support plate 1 is level. When water flows out of the seepage hole 12, the surveying and mapping is stopped.

[0039] During the surveying process, if the ground is muddy and the support rod 5 sinks, causing the device to tilt, the above process is repeated and the device can automatically adjust to a horizontal state.

[0040] Example 3

[0041] like Figure 1-4 As shown, when other parts are the same as those of embodiment 2, the difference between this embodiment and embodiment 2 is that a pointed head 8 is fixedly provided at the lower end of the support rod 5. By providing the pointed head 8, the support rod 5 can be more stably erected on the ground.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
