[0002] In the process of geodetic surveying, leveling instruments are often used for measurement, and leveling operations are required for the leveling instruments.

[0003] Existing levels typically use multiple adjustment knobs for leveling. However, this method is cumbersome, slow, and inefficient.

[0004] During measurement, if the support base of the bracket shakes, the level will also shake, causing it to tilt. If this is not detected and readjusted in time, the measurement results will be inaccurate.

[0005] The present invention is proposed to alleviate or solve at least one aspect or point of the above-mentioned problems. Summary of the Invention

The water tank is filled with water, and the first float plate can float in the water. The first float plate includes a top surface, which floats above the water surface and has a regular polygonal structure. The inner wall of the water storage tank is equipped with a slide rail, which together with the inner wall of the water storage tank defines a floating space, within which the second float can float. A spring is provided between the first float and the second float. The second float is made of the same material as the first float and is a polygonal column structure. The top surface of the first floating plate is symmetrically provided with two sets of identical rotating components, power components and transmission components. The power components can drive the rotating components to rotate through the transmission components. The top surface of the first floating plate is also equipped with a level correction device and a level measuring device. The level measuring device includes a level ring and multiple level columns. The level ring is connected to the multiple level columns, and the multiple level columns are marked. The center of the horizontal ring and the center of the top surface are set at the same center, and multiple horizontal columns are evenly distributed along the horizontal ring; The horizontal correction device includes multiple identical sliding grooves evenly distributed on the top surface, with the multiple sliding grooves symmetrically and evenly distributed along the center of the top surface; The leveling device also includes multiple adjusting plates that cooperate with multiple slides, and the multiple adjusting plates are identical in size, material and structure.

[0009] Preferably, one end of the spring is fixed to the center of the first float and the other end is fixed to the center of the second float, and the first float and the second float float float synchronously with the water.

[0010] Preferably, the specific method of "the inner wall of the water storage tank is provided with a slide rail, and the slide rail and the inner wall of the water storage tank together define a floating space, and the second float can float in the above-mentioned floating space" is as follows: the slide rail includes a first limiting plate and a second limiting plate, the first limiting plate restricts the movement of the second float in a first direction, and the second limiting plate restricts the movement of the second float in a second direction; a first preset gap is provided between the first limiting plate and the second float, and a second preset gap is provided between the second limiting plate and the second float.

[0011] Preferably, the rotating assembly includes a first turntable, a second turntable, a first rotating support structure, and a second rotating support structure; the first turntable has a first mating groove, and the second turntable has a second mating groove.

[0012] Preferably, it also includes a first measuring instrument and a second measuring instrument, wherein a first mating post and a second mating post are formed on the first measuring instrument and the second measuring instrument.

However, these embodiments are merely examples for those skilled in the art, and the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this invention.

[0034] According to an exemplary embodiment of the present invention: Figure 1-7 As shown, a rapid leveling instrument for geodetic surveying includes a telescopic rod 10, a support base 11, a water tank 13, a first float 20, a second float 21, and a spring. Figure 1-3 As shown, the telescopic rod 10 has a multi-section structure, with one end being a pointed tip for easy insertion into the ground, and the other end hinged to the support base 11 via a hinge structure 12. The telescopic rod 10 serves as a support leg, and its existing structure can be used. The support base 11 has a circular structure, and a water storage tank 13 is fixedly connected to the middle of the support base 11, wherein the water storage tank 13 is fixedly connected to the support base 11 or integrally formed therein. Optionally, an opening is formed in the middle of the support base 11, and the water storage tank 13 is fixedly installed in the opening.

[0035] like Figure 1-7 As shown, the exemplary water storage tank 13 of the present invention has a cuboid structure with a square cross-section.

[0036] The first float 20 is made of a uniform material plate, and it is a regular polygonal column structure or a cylindrical structure. Optionally, it is a square structure. By having the above-mentioned centrally symmetrical structure, when equipment is placed on its top surface, it can still maintain a horizontal state in the water by placing the equipment in a centrally symmetrical manner.

[0037] The first float 20 has a circular or regular polygonal cross-section. The water tank 13 can be used to hold water, and the first float 20 can float in the water. The first float 20 includes a top surface that floats above the water surface. The top surface has a regular polygonal or circular structure. Since the first float 20 is made of a uniformly shaped plate, when it floats on a horizontal surface, its top surface automatically remains on the same horizontal plane when the water is still.

[0038] Illustration of the present invention Figure 1-7In the middle, the cross-section of the first floating plate 20 is a square structure, and the cross-section formed by the inner wall of the water storage tank 13 is also a square structure.

[0039] To ensure relative stability of the first float 20, the present invention also includes a second float 21. A slide rail 14 is provided on the inner wall of the water tank 13, and the second float 21 can slide along the slide rail 14. A spring is provided between the first float 20 and the second float 21. The second float 21 is made of the same material as the first float 20 and is a polygonal column structure. Therefore, the second float 21 can float in the same manner as the first float 20.

[0040] The second float 21 is at the same height as the first float 20. One end of the spring is fixed to the center of the first float 20, and the other end is fixed to the center of the second float 21. The first float 20 and the second float 21 float synchronously with the water.

[0041] The inner wall of the water storage tank 13 is provided with a slide rail 14, which together with the inner wall of the water storage tank 13 defines a floating space within which the second float 21 can float. Specifically, the slide rail 14 includes a first limiting plate 16 and a second limiting plate 17. The first limiting plate 16 restricts the movement of the second float 21 in a first direction, and the second limiting plate 17 restricts the movement of the second float 21 in a second direction. A first preset gap is provided between the first limiting plate 16 and the second float 21, and a second preset gap is provided between the second limiting plate 17 and the second float 21. Through the above arrangement, on the one hand, the first float 20 can be kept relatively stable, and on the other hand, it is not affected by the second float 21.

[0042] like Figure 2 As shown, there are four second float plates 21, which are evenly distributed on the inner wall of the water storage tank 13.

[0043] The top surface of the first float 20 is a regular polygonal or circular structure, thus forming a symmetrical center line. Two identical turntables, namely the first turntable 33 and the second turntable 43, are symmetrically arranged on the top surface of the first float 20. The first turntable 33 and the second turntable 43 are centrally symmetrically arranged, so that after the first turntable 33 and the second turntable 43 are placed, the top surface of the first float 20 remains in a roughly horizontal position in the water.

[0044] The first float plate 20 is also provided with a first rotary support structure 35 and a second rotary support structure 45, which respectively cooperate with the first turntable 33 and the second turntable 43. The first rotary support structure 35 is used to provide rotary support for the first turntable 33, and the second rotary support structure 45 is used to provide rotary support for the second turntable 43. Optionally, the first rotary support structure 35 and the second rotary support structure 45 can be thrust bearings.

[0045] Two identical power components and transmission components are symmetrically arranged along the center line of symmetry on the first floating plate 20. The power components can be stepper motors, and the transmission components can be gear assemblies. As shown in the figure, the power components include a first power device 30 and a second power device 40; the transmission components include a first gear 31, a second gear 32, a third gear 41, and a fourth gear 42. Of course, other transmission methods, such as belt drives, can also be used, all of which are within the protection scope of this invention.

[0046] The top surface of the first float 20 is also equipped with a leveling device and a leveling measuring device. The leveling measuring device includes a leveling ring 24 and a leveling column 25, with the leveling ring 24 and the leveling column 25 connected. The leveling column 25 has markings. The markings indicate whether it is level. The leveling ring 24 is filled with water, and due to the principle of communicating vessels, the water in the leveling column 25 is at the same level. Optionally, the outer circumference of the leveling column 25 has graduations. By observing whether the water in the leveling column 25 is at the same graduation, it can be determined whether the leveling ring 24 is at the same level, and thus whether the first float 20 is in a level position.

[0047] The horizontal correction device includes multiple identical sliding grooves 22 evenly distributed on the top surface, and multiple adjusting plates 23 that cooperate with the multiple sliding grooves 22. The multiple adjusting plates 23 are identical in size, material and structure.

[0048] The horizontal ring 24 is circular, and its center coincides with the center of the regular polygon on the top surface. The horizontal columns 25 are evenly distributed along the horizontal ring 24. The number of multiple grooves 22 is the same as the number of horizontal columns 25, and the groove direction of the grooves 22 is set directly opposite to the direction of the horizontal columns 25.

[0049] The rotating assembly includes a turntable and a rotating support structure. One side of the turntable is connected to a second rotating shaft, and the other side has a mating groove. The turntable includes a first turntable 33 and a second turntable 43. A first mating groove 34 is formed on the first turntable 33, and a second mating groove 44 is formed on the second turntable 43.

[0050] The present invention also includes a first measuring instrument 50 and a second measuring instrument 51. A first mating post 52 is formed on the first measuring instrument 50, and a second mating post 53 is formed on the second measuring instrument 51. The first mating post 52 and the second mating post 53 are used to mate with the first mating groove 34 and the second mating groove 44, respectively. like Figure 1-7 As shown, it also includes fixing posts 15. By rotating the fixing posts 15, they can be abutted against the outer periphery of the first floating plate 20 to achieve fixation. Two fixing posts 15 are provided on each side, symmetrically arranged. Threads are formed on the fixing posts 15.

[0051] like Figure 1-7As shown, the present invention also provides a method for using a rapid leveling instrument for geodetic surveying, which includes the following steps when precise leveling is not required: Select the measurement location; Insert the support legs, or telescopic rods, into the ground; The first measuring instrument is installed on the first turntable 33, and the second measuring instrument is placed on the second turntable 43, wherein the first measuring instrument and the second measuring instrument are placed opposite each other along the center line of symmetry.

[0052] Take a measurement once the water in the storage tank 13 stops sloshing. During the measurement, rotate the first power unit 30 and the second power unit at the same angle. Take the measurement once the water stops sloshing.

[0053] Alternatively, a fixing step can be added to the above steps. After the support leg is inserted into the ground and the water level is stable, the first floating plate 20 can be fixed relative to the ground by fixing column 15.

[0054] When precise measurements are required, the following steps can be taken: Select the measurement location; Insert the support legs into the ground; The first measuring instrument is installed on the first turntable 33, and the second measuring instrument is placed on the second turntable 43, wherein the first measuring instrument and the second measuring instrument are placed opposite each other along the center line of symmetry.

[0055] Take a measurement once the water in the storage tank 13 stops sloshing. During the measurement, rotate the first power unit 30 and the second power unit at the same angle. Take the measurement once the water stops sloshing.

[0056] Observe whether the water level line on the horizontal column 25 is at the same water level. If it is not at the same water level, adjust the adjusting block to make it horizontal.

[0057] Alternatively, a fixing step can be added after the above steps. After the water level stabilizes, the first floating plate 20 can be fixed relatively by the fixing column 15, which is beneficial for subsequent observation.

[0058] This invention relates to a rapid leveling instrument for geodetic surveying and its usage method. Through the setting of a water tank 13, utilizing the principle of levelness, a first float 20 made of uniform material ensures its top surface remains horizontal, eliminating the need for leveling. The addition of a second float 21 further increases the stability of the first float 20, preventing it from swaying due to water flow and increasing its vibration resistance. Simultaneously, the second float 21 is made of the same material as the first float 20, placing them on the same floating surface to avoid affecting the levelness of the first float 20. The equipment on the first float 20 is arranged symmetrically around its center, ensuring that the first float 20 remains automatically horizontal when floating in water. During use, relative rotation is employed to maintain its balance, thus automatically achieving equilibrium. This invention significantly improves the speed of leveling and simplifies the adjustment process.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations and combinations of elements may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
