[0002] In the construction and maintenance of water conservancy projects, the accuracy and stability of surveying instruments play a crucial role in the quality of the project. Currently, the commonly available fixed bases for water conservancy engineering surveying instruments have relatively simple structural designs, and their main function is limited to supporting and fixing the surveying instruments. The installation of the instruments is achieved through conventional methods such as bolt connections and slot positioning.

[0003] However, in actual water conservancy engineering surveying operations, due to the complex and ever-changing environment of water conservancy projects, which often involve harsh scenarios such as water bodies, wetlands, and the field, instruments are always exposed to the outside. On the one hand, instruments exposed to the natural environment for a long time are susceptible to corrosion from harsh weather conditions such as wind, rain, sandstorms, and scorching sun, which accelerates the aging and damage of instrument components and shortens the service life of the instruments. On the other hand, during field operations, there may also be unexpected situations such as human collisions and animal damage, which increases the risk of instrument damage. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Refer to Figures 1 to 3 A fixed base for a water conservancy engineering surveying instrument includes a surveying instrument body 5 and a support base 1. Multiple support legs 2 are fixed in a ring array at the lower end of the support base 1, providing a stable support foundation for the entire base. It is suitable for complex terrains such as water areas and wetlands in water conservancy projects.

[0023] The support base 1 is slidably connected to a lifting ring 3, and the lifting ring 3 is slidably connected to the support base 1. The upper end of the lifting ring 3 is fixedly connected to a placement plate 4 for supporting the main body 5 of the surveying instrument. The placement plate 4 is used to support the main body 5 of the surveying instrument, so as to realize the horizontal installation and positioning of the instrument.

[0024] A protective shell 6 is fixedly installed on the upper end of the support base 1 on the outside of the main body 5 of the surveying instrument. Two protective covers 7 are symmetrically rotatably connected to the upper end of the protective shell 6. Two telescopic cranks 8 are symmetrically arranged on the inner side wall of the protective shell 6. The other ends of the two telescopic cranks 8 are connected to the protective covers 7. Multiple springs 9 are fixedly connected between the protective covers 7 and the inner side wall of the protective shell 6. When the instrument needs to be used, the protective covers 7 can be rotated upward to open, and the thin rod 82 of the telescopic crank 8 slides and extends in the thick rod 81, and the springs 9 are stretched and stored. When not in use, the protective covers 7 automatically close under the elastic force of the springs 9, forming a closed space with the protective shell 6 to prevent damage to the instrument from wind, rain, sand, dust, animal collisions, etc.

[0025] Multiple springs 9 are arranged one-to-one on the outside of the telescopic crank 8 to ensure that the springs 9 are not prone to elastic deformation.

[0026] The telescopic curved rod 8 includes a thick rod 81 fixedly connected to the inner wall of the protective shell 6. The thick rod 81 has a sliding cavity, and a thin rod 82 is slidably connected to the sliding cavity. The thin rod 82 is connected to the protective cover 7. When the main body of the surveying instrument 5 moves upward, it can push the two protective covers 7 to flip upward, so that the main body of the surveying instrument 5 can be extended for surveying operations.

[0027] The lower end of the support base 1 is provided with a drive assembly for driving the lifting and lowering of the shelf 4. Specifically, the drive assembly includes a rotary motor 10 fixedly installed at the lower end of the support base 1. A threaded rod 11 is fixedly connected to the output end of the rotary motor 10. A lifting plate 12 is threadedly sleeved on the outer side of the threaded rod 11. A guide rod 14 is fixedly connected to the lower end of the support base 1, and the guide rod 14 is slidably connected to the lifting plate 12. The guide rod 14 ensures the stability of the lifting plate 12 during the lifting process.

[0028] Two lifting rods 13 are symmetrically fixedly connected to the upper end of the lifting plate 12. The upper ends of the two lifting rods 13 are fixedly connected to the placement plate 4. The rotary motor 10 drives the threaded rod 11 to rotate, which drives the lifting plate 12 to move up and down along the guide rod 14. The height of the placement plate 4 is adjusted synchronously through the lifting rods 13 to realize the lifting function of the main body of the surveying instrument 5 and meet the different working height requirements.

[0029] The lower end of the guide rod 14 is fixedly connected to the limit block 15, and the upper end of the limit block 15 is equipped with a proximity sensor. The proximity sensor signal is connected to the controller, which is electrically connected to the rotary motor 10. When the lifting plate 12 descends to the appropriate position, that is, the main body 5 of the surveying instrument is housed in the protective shell 6 and the two protective covers 7 are closed, the proximity sensor detects that the lifting plate 12 is close to the limit block 15. The controller automatically cuts off the power to the rotary motor 10 to prevent the threaded rod 11 from rotating excessively and causing structural damage, thereby improving the safety and reliability of the equipment operation and realizing the automatic shutdown of the rotary motor 10.

[0030] The working principle of this utility model is as follows:

[0031] When in use, the rotary motor 10 starts, and the threaded rod 11 drives the lifting plate 12 to rise. The lifting rod 13 pushes the placement plate 4 and the main body of the surveying instrument 5 to rise above the protective shell 6. At this time, the main body of the surveying instrument 5 lifts the protective cover 7, the two protective covers 7 flip up and open, the spring 9 is stretched, the telescopic rod 8 is extended, and the main body of the surveying instrument 5 extends and enters the working state.

[0032] After the operation is completed, when the lifting plate 12 is lowered to the appropriate position, the main body of the surveying instrument 5 is stored in the protective shell 6. The proximity sensor detects that the lifting plate 12 is close to the limit block 15, and the controller automatically cuts off the power to the rotary motor 10. The protective cover 7 automatically closes under the elastic force of the spring 9, thus completing the storage and protection of the instrument.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
