[0029] First embodiment

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , where Figure 1 is a schematic structural diagram of the first embodiment of a topographic surveying device for the construction land of a bridge dam in a water conservancy project provided by the present invention; Figure 2 is Figure 1 an enlarged schematic diagram of part A shown in; Figure 3 is Figure 1 a three - dimensional structural schematic diagram of the topographic surveying device shown in. A topographic surveying device for the construction land of a bridge dam in a water conservancy project includes:

[0031] A surveying instrument main body 1, and a bracket 2 is connected to the bottom of the surveying instrument main body 1;

[0032] A moving component 3, and the moving component 3 is arranged on the surface of the bracket 2;

[0033] A stepping component 4, and the stepping component 4 is arranged below the moving component 3. The stepping component 4 includes a circular stepping block 41 and two L - shaped fixing rods 42. The two L - shaped fixing rods 42 are symmetrically connected to the left and right sides of the surface of the circular stepping block 41.

[0034] The moving component 3 includes a fixing frame 31, two fixing rods 32, two moving sleeves 33, two springs 34 and two stoppers 35. The fixing frame 31 is sleeved on the surface of the bracket 2, and the two fixing rods 32 are symmetrically connected to the left and right sides of the bottom of the fixing frame 31.

[0035] The two moving sleeves 33 are sleeved on the surfaces of the two fixing rods 32, and the two L - shaped fixing rods 42 are respectively connected to one side of the two moving sleeves 33.

[0036] The use of the stopper 35 can prevent the spring 34 and the moving sleeve 33 from falling off, and the size of the stopper 35 is larger than the size of the spring 34.

[0037] The two springs 34 are sleeved on the surfaces of the two fixing rods 32 and are located below the two moving sleeves 33.

[0038] The use of the spring 34 allows the circular pressing block 41 to return to its original position after loosening. The circular pressing block 41 is sleeved on the surface of the bracket 2 and moves up and down. The use of the fixed rod 32 and the movable sleeve 33 can drive the circular pressing block 41 to move.

[0039] The two stoppers 35 are respectively connected to the bottom ends of the two fixed rods 32.

[0040] A placement rack 5 is installed on the surface of the bracket 2.

[0041] The working principle of a topographic surveying device for the construction land of bridges and dams in water conservancy projects provided by the present invention is as follows:

[0042] During use, after adjusting the position of the tester main body 1, the operator moves the circular pressing block 41 downward towards the ground by stepping on it with the foot. When the circular pressing block 41 moves downward towards the ground, it drives the movable sleeve 33 to move downward on the surface of the fixed rod 32 through the L-shaped fixed rod 42. When the movable sleeve 33 moves downward on the surface of the fixed rod 32, it squeezes the spring 34 on the surface until the circular pressing block 41 moves to contact the ground and continues to be stepped on for use. At this time, the operator can operate the surveying instrument main body 1 and other operating instruments.

[0043] Compared with the related technology, a topographic surveying device for the construction land of bridges and dams in water conservancy projects provided by the present invention has the following beneficial effects:
