Hydraulic engineering surveying equipment mainly includes levels, theodolites, total stations, and GPS, which play a crucial role in the surveying and design of hydraulic engineering projects.

[0003] Currently, most existing surveying equipment is equipped with a level bubble, but the level bubble is easily damaged by weather and external impacts, requiring the surveying equipment to be replaced before work can proceed, which affects efficiency. Utility Model Content

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a surveying device for water conservancy projects, comprising multiple support rods 1, with inner rods 2 slidably disposed within the support rods 1, and an adjustment mechanism for adjusting the sliding position of the support rods 1 on the inner rods 2. A connecting block 4 is fixed to the top of the inner rod 2, and the same rotating frame 5 is hinged between the multiple connecting blocks 4. The rotating frame 5 is provided with a drive mechanism for synchronously driving the multiple inner rods 2 to open and close. A support frame 6 is fixed to the upper surface of the rotating frame 5, and a surveying instrument 7 is rotatably mounted between the support frames 6 via a rotating component. A turntable 8 is fixed to the end of the rotating component, and a level bubble 10 is detachably disposed on the turntable 8.

[0025] By setting up a drive mechanism, support rod 1, inner rod 2, and adjustment mechanism, the drive mechanism can quickly drive multiple inner rods 2 and support rods 1 to be deployed or folded for dismantling. At the same time, the adjustment mechanism facilitates the adjustment of the position of individual support rod 1. The position of support rod 1 can be adjusted by sliding it up and down, which is convenient for use on slopes and improves the stability of support rod 1 and inner rod 2, preventing support rod 1 from tilting and collapsing. By setting up a level bubble 10, turntable 8, and surveying instrument 7, adjusting the angle of surveying instrument 7 drives turntable 8 to rotate synchronously. Turntable 8 drives level bubble 10 to rotate synchronously. The level bubble 10 can be used to determine whether surveying instrument 7 is in a horizontal position, ensuring the accuracy of the survey.

[0026] Reference Figure 3The driving mechanism includes a threaded rod 14 rotatably mounted at the bottom of the rotating frame 5. A rotating plate is fixed to the end of the threaded rod 14, and a movable plate 15 is threadedly mounted on the outer surface of the threaded rod 14. Multiple connecting rods 16 are rotatably mounted on the movable plate 15, and a connecting sleeve 20 is rotatably mounted on the other end of the connecting rod 16. The connecting sleeve 20 is mounted on adjacent inner rods 2. By setting up the threaded rod 14, the movable plate 15, and the connecting rods 16, rotating the rotating plate drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 drives the movable plate 15 to move up and down. The movement of the movable plate 15 drives the connecting rods 16 to follow the movement. At the same time, the rotation of the connecting rods 16 drives the inner rods 2 to move away from or closer to each other, realizing the synchronous opening and folding of multiple inner rods 2 without the need for repeated unfolding and fixing, thus improving the convenience of operation.

[0027] Reference Figure 4 and Figure 5 The adjustment mechanism includes a rod 12 that is slidably disposed on the outer surface of the support rod 1, and a pull plate 11 is fixed to the end of the rod 12. The inner rod 2 has several insertion holes for the rod 12 to be inserted. By setting the pull plate 11 and the rod 12, pulling the pull plate 11 can disengage the rod 12 from the insertion hole, thereby quickly releasing the fixation of the inner rod 2. Inserting the rod 12 into the insertion hole can effectively limit the inner rod 2 and prevent the inner rod 2 from sliding up and down. The structure is simple and easy to operate.

[0028] Reference Figure 5 A spring 13 is fixed to the outer surface of the insertion rod 12. The two ends of the spring 13 are fixedly installed on the pull plate 11 and the support rod 1, respectively. By setting the spring 13, the elasticity of the spring 13 drives the insertion rod 12 to automatically insert into the insertion hole, effectively avoiding the problem of the insertion rod 12 coming off during use.

[0029] Reference Figure 2 The turntable 8 has a groove, and a mounting bracket 9 is fixed inside the groove. The level bubble 10 is set on the mounting bracket 9. On both sides of the level bubble 10, there are fixing plates 19 provided by elastic elements. The fixing plates 19 have grooves for placing the level bubble 10. By setting the elastic elements and fixing plates 19, the elastic elements drive the fixing plates 19 on both sides to move closer to each other, so as to realize the installation of the level bubble 10. Pushing the fixing plates 19 away from the level bubble 10, the level bubble 10 can be disassembled, which facilitates the quick replacement of the level bubble 10 without changing the equipment and affecting work efficiency.

[0030] Reference Figure 2 The elastic element includes a second spring 17 mounted on two fixed plates 19. The other end of the second spring 17 is fixedly mounted on the inner wall of the mounting bracket 9. By setting the second spring 17, the elasticity of the second spring 17 can drive the two fixed plates 19 to move closer together and quickly reset, automatically fixing the bubble level 10. The operation is simple and convenient.

[0031] Reference Figure 2 The second spring 17 is equipped with a telescopic rod 18. The two ends of the telescopic rod 18 are fixedly installed on the inner wall of the mounting bracket 9 and the fixing plate 19, respectively. By setting the telescopic rod 18, the telescopic rod 18 plays a supporting and guiding role for the second spring 17, avoiding the problem of displacement and skew during the movement of the fixing plate 19 and the second spring 17, and improving stability.

[0032] Reference Figure 1 Multiple support rods 1 are rotatably mounted with ground nails 3 at their bottom ends. By setting the ground nails 3 and inserting them into the ground, the support rods 1 are fixed, preventing slippage and displacement, and further improving the stability of the support rods 1.

[0033] Working principle: Rotating the rotating plate drives the threaded rod 14 to rotate, which in turn drives the moving plate 15 to move up and down. The movement of the moving plate 15 drives the connecting rod 16 to follow suit. At the same time, the rotation of the connecting rod 16 causes the inner rods 2 to move away from each other, so that multiple inner rods 2 open synchronously, allowing the ground nails 3 to be inserted into the ground to complete the erection work. If the ground is uneven, pull the pull plate 11 to disengage the insertion rod 12 from the insertion hole, releasing the fixation of the inner rod 2. Adjust the position of the support rod 1 according to the slope of the ground. After adjusting the position, release the pull plate 11, and the insertion rod 12 will be inserted into the insertion hole under the action of the spring 13, thus fixing the support rod 1. Then, adjust the angle of the surveying instrument 7 and determine the levelness of the surveying instrument 7 by using the bubble level 10 on the through turntable 8. After the adjustment is completed, the test can be performed.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
