[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the surveying equipment for assisting land surveys according to this utility model includes a support plate 1, a bracket 2, and a sleeve 3. The lower outer wall of the support plate 1 is screwed with a circular array of clamping sleeves 12. The bracket 2 is rotatably installed inside the clamping sleeves 12. The upper side of the inner wall of the bracket 2 is screwed with a sleeve 3. A piston rod 31 is movably installed inside the sleeve 3. A baffle 32 is installed on one end of the outer wall of the sleeve 3 through the piston rod 31. Ventilation slots 21 are symmetrically opened inside the bracket 2. Exhaust pipes 22 in a rectangular array are inserted and installed on both sides of the inner wall of the bracket 2. A pressure relief valve 38 is inserted and installed on one side of the outer wall of the sleeve 3. When the support leg 33 moves with the piston rod 31 to the position relative to the exhaust pipe 22, the gas inside the sleeve 3 is compressed into compressed gas. The pressure threshold of the pressure relief valve 38 is set to be lower than the gas value at this time, so that when the support leg 33 moves into the position relative to the exhaust pipe 22, the gas inside the sleeve 3 can be discharged through the pressure relief valve 38.

[0031] During use, the clamp 12 ensures that the bracket 2 can be flexibly adjusted to adapt to different terrain requirements. When conducting land surveying on uneven ground, each bracket 2 can be adjusted to a suitable angle according to the actual terrain, ensuring that the support plate 1 is in a relatively horizontal state, thereby providing a stable support foundation for the surveying instrument 11. When the operator pushes the baffle 32 to move using the foot pedal 34, the piston rod 31 will move out of the sleeve 3, and outside air will enter the sleeve 3 through the air inlet pipe 36. The air filling the sleeve 3 supports the piston rod 31, ensuring the stability of the piston rod 31 and the extended support leg 33. This real-time support allows for position adjustment of the support leg 33, improving the convenience of position adjustment. To improve the installation efficiency of the surveying instrument 11, when the staff manually pushes the support leg 33 and piston rod 31 to move upward and reset, the gas inside the sleeve 3 can be compressed through the piston rod 31. When the support leg 33 moves to the position relative to the exhaust pipe 22, the pressure of the compressed gas inside the sleeve 3 is greater than the set pressure of the pressure relief valve 38. Thus, the compressed gas inside the sleeve 3 can flow into the ventilation groove 21 through the pressure relief valve 38 and the connecting pipe 35. Finally, the gas inside the ventilation groove 21 is discharged at multiple points through the exhaust pipe 22 and the nozzle 23. The sprayed gas impacts the outer wall of the support leg 33, which can clean the dirt on the outer wall of the support leg 33, ensuring the cleanliness of the surface of the support leg 33, avoiding manual cleaning by the staff, and ensuring the cleaning efficiency of the equipment.

[0032] For the purpose of mapping, exemplarily, such as Figure 1 As shown, a surveying instrument 11 is installed on the outer wall of the upper end of the support plate 1.

[0033] When in use, the support plate 1 provides a stable installation platform for the surveying instrument 11, ensuring that the surveying instrument 11 remains stable during the measurement process, thereby ensuring the accuracy and reliability of the surveying, and the surveying instrument 11 is able to perform land surveying.

[0034] For ease of adjusting the extension length, for example, such as Figure 2 As shown, a foot pedal 34 is installed on one side of the outer wall of the baffle 32. The foot pedal 34 is located outside the bracket 2. A support leg 33 is installed on the lower outer wall of the baffle 32. The support leg 33 adopts a conical shape design.

[0035] During use, the operator drives the piston rod 31 to move within the sleeve 3 by stepping on the foot pedal 34, ensuring that the baffle 32 can be moved easily, and the tapered support foot 33 can be easily inserted into the ground, which can enhance the support stability of the equipment on the convex surface.

[0036] To clean the support leg 33, for example, such as Figure 4 As shown, the outer wall of the exhaust pipe 22 is designed with a curved shape, and a nozzle 23 is inserted and installed on the outer wall of one end of the exhaust pipe 22. The nozzle 23 is connected to the inside of the ventilation groove 21 through the exhaust pipe 22.

[0037] When in use, the gas inside the ventilation groove 21 can be ejected through the nozzle 23, and the gas discharged from the nozzle 23 can be ejected obliquely downward according to the bending angle of the exhaust pipe 22, so that the gas can impact the surface of the support leg 33 and help the fallen soil fall downward, avoiding the soil from contaminating the support leg 33.

[0038] For air intake, for example, such as Figure 3 As shown, an air inlet pipe 36 is inserted and installed on the outer wall of the sleeve 3 on the side away from the pressure relief valve 38, and a one-way valve 37 is inserted and installed on the outer wall of the air inlet pipe 36.

[0039] When in use, the one-way valve 37 allows air to enter the sleeve 3 while preventing air from flowing back into the sleeve 3. When the piston rod 31 moves outward, a negative pressure is formed inside the sleeve 3, and air enters the sleeve 3 through the air inlet pipe 36 and the one-way valve 37, and the gas is stored inside the sleeve 3.

[0040] For the purpose of venting, for example, such as Figure 3 As shown, connecting pipes 35 are inserted and installed on both outer walls of the pressure relief valve 38. The connecting pipes 35 are inserted and installed inside the venting groove 21, and the sleeve 3 is connected to the inside of the venting groove 21 through the pressure relief valve 38 and the connecting pipes 35.

[0041] During use, the air inside the sleeve 3 can be discharged into the venting groove 21 under pressure through the pressure relief valve 38, and then discharged into the venting groove 21 through the exhaust pipe 22.

[0042] To control the extension length, for example, such as Figure 2 As shown, the length of piston rod 31 is less than the length of sleeve 3, and piston rod 31 adopts a rectangular shape design.

[0043] When in use, the piston rod 31 can move inside the sleeve 3, and its rectangular shape ensures that the movement direction of the piston rod 31 is stable, preventing the piston rod 31 from rotating inside the sleeve 3.

[0044] In use, the operator rotates the bracket 2 using the clamp 12 to adjust each bracket 2 to a suitable angle. The operator then steps on the foot pedal 34 located on the outside of the bracket 2. The foot pedal 34 pushes the baffle 32 to move, thereby causing the piston rod 31 connected to the baffle 32 to move out of the sleeve 3. At this time, a negative pressure is formed inside the sleeve 3, and outside air enters the sleeve 3 through the air inlet pipe 36 and the one-way valve 37. As the gas continuously fills the sleeve 3, it supports the piston rod 31 and allows the support feet 33 to be inserted into the ground, further enhancing the stability of the equipment on the ground. By adjusting the extension length of the support feet 33, the levelness of the support plate 1 can be adjusted to ensure that the surveying instrument 11 is in a stable state. After that, the operator can use the surveying instrument 11 to carry out land surveying work.

[0045] After the surveying work is completed, the staff manually pushes the support leg 33 and piston rod 31 to move upward and reset. During this process, the piston rod 31 compresses the gas inside the sleeve 3.

[0046] When the support leg 33 moves to the position opposite to the exhaust pipe 22, the pressure of the compressed gas inside the sleeve 3 is greater than the set pressure of the pressure relief valve 38, and the pressure relief valve 38 opens. At this time, the compressed gas inside the sleeve 3 flows into the ventilation groove 21 through the pressure relief valve 38 and the connecting pipe 35. Since the outer wall of the exhaust pipe 22 is designed with a curved shape, the gas inside the ventilation groove 21 is discharged from multiple points at an angle downward through the exhaust pipe 22 and the nozzle 23. The sprayed gas impacts the outer wall of the support leg 33, cleaning the dirt off the outer wall of the support leg 33 and ensuring the cleanliness of the surface of the support leg 33.
