The leveling instrument designed in this embodiment is operated by first carrying the base 1 and the leveling instrument body to a construction site by an operator, then taking out the base 1 and adjusting the height of the lifting plate 14 by adjusting the push rod 16, so that the supporting devices 7 are opened to the outside of the base 1, then manually adjusting the extension length of the middle rod 704 and the included angle between the bottom rotating rod 706 and the middle rod 704 on each supporting device 7, so that the base 1 is placed on the ground by three supporting devices 7, when the ground is softer and easy to loosen when the leveling instrument is used later, the pushing handle 603 can be pinched to insert the limiting rod 601 into the corresponding positioning hole 31, so that the inserting fixing column 604 is rotated to a proper working angle from the bottom rotating rod 706 and inserted into the ground to fix the base 1, after the base 1 is initially supported and fixed, the second level bubble 11 and the horizontal calibration device 5 can be used for calibration, wherein the second level bubble 11 is used for initial calibration, when the air bubble in the second level bubble 11 basically reaches the horizontal indication position through adjusting the supporting device 7 and the fixing device 6, the horizontal calibration device 5 can be replaced for more accurate adjustment, when the horizontal calibration device 5 is used, an operator firstly opens the light-emitting lamp beads 506 through the calibration switch 504, then combines the deflection directions of the air bubble in the second level bubble 11, and fine-adjusts the position of the base 1 through the supporting device 7 and the fixing device 6, so that the light emitted by the light-emitting lamp beads 506 can pass through the second light guide tube 507 and the third light guide tube 508 and irradiate on the calibration center mirror 509, and finally the light is stabilized on the calibration center mirror 509, compared with the mode of visually observing bubbles, the mode of adopting the light positioning is more accurate, the error caused by different observation angles of operators can be effectively eliminated, the base 1 is ensured to be more horizontal, and the phenomenon that the level body cannot be adjusted to the horizontal position due to too large error caused by the base 1 when the level body is adjusted later is avoided. After the position of the base 1 is adjusted, the level body can be placed on the base 1, then the tail end of the limit push rod 10 is driven by the controller 22 to be fixedly connected with the butt joint seat 13 in an inserting way, so that the level body and the base 1 can be firmly fixed, then an operator can give an automatic leveling instruction to the level body through the controller 22, at the moment, the clamping push rod 307 is retracted to a non-working position, then the electromagnet 19 is electrified, the magnetic cone 304 in the inclination detection device 3 is rapidly stopped and rocked under the adsorption of the electromagnet 19, then the electromagnet 19 is closed, the magnetic cone 304 is rapidly returned to a vertical position and is static under the action of gravity, meanwhile, the heater 18 also heats the interior of the inclination detection device 3 to enable the temperature of each part in the first closed cylinder 302 to reach a preset working temperature, so that the deformation influence caused by different temperatures is eliminated, when the temperature reaches the preset value, the controller 22 electrifies the magnetic cone 304, if the level body is in a non-horizontal state, the magnetic cone 304 contacts with the conductive detection sheet 305 at the corresponding angle position to form a detection loop, the controller 22 can rotate the corresponding second angle screw 28 through the corresponding driving motor 8 according to the position of the conductive detection sheet 305 contacted at the moment, thereby fine-tuning the position of the rotating seat 20, and further, whether the magnetic cone 304 and the conductive detection sheet 305 at other positions form a loop needs to be continuously detected in the fine-tuning process until the magnetic cone 304 is not contacted with any conductive detection sheet 305, the rotating seat 20 is considered to be in a horizontal state, the automatic leveling process is finished, the clamping push rod 307 drives the clamping ring 303 to clamp the magnetic cone 304 again, the situation that deformation of the magnetic cone 304 is caused by shaking and collision in the subsequent use process to influence future detection precision is avoided, it is required to say that the inclination detection device 3 internally adopts a plurality of conductive detection pieces 305 which are arranged on the matching seat 306 in a ring-shaped array to detect the inclination direction of the magnetic cone 304, each conductive detection piece 305 is individually numbered and represents a corresponding inclination angle, so that the subsequent accurate detection of the inclination angle of the magnetic cone 304 is facilitated, when the number of the conductive detection pieces 305 used on the matching seat 306 is larger, the detected inclination precision of the magnetic cone 304 is higher, so that fewer detection rounds are required for leveling in automatic adjustment, but the gap between the adjacent conductive detection pieces 305 does not have a detection function because insulation isolation is required between the conductive detection pieces 305, and at the moment, if the magnetic cone 304 is in contact with the gap, the controller 22 cannot distinguish whether the rotating seat 20 is in a horizontal position at the moment, so that two feasible solutions are provided: the first solution is to arrange two circles of conductive detection pieces 305 at different heights of the same matching seat 306, so that the direction of a gap between the conductive detection pieces 305 positioned at the upper circle is complemented by the conductive detection pieces 305 positioned at the lower circle for detection, thereby realizing full-angle coverage detection; the second solution is that at least two tilt detecting devices 3 are installed at different positions of the rotating base 20, the tilt detecting devices 3 are subjected to angle adjustment, so that the direction of a gap between conductive detecting pieces 305 on one tilt detecting device 3 can be covered by the conductive detecting pieces 305 installed on the other tilt detecting devices 3, thereby realizing full-angle coverage detection by utilizing a plurality of tilt detecting devices 3, and redundant tilt detecting devices 3 can be further arranged to realize checking on the basis of meeting the full-angle coverage detection, thereby rapidly identifying the problem of error caused by damage occurring in a single tilt detecting device 3 when the detection results are inconsistent between the tilt detecting devices 3 for checking and the tilt detecting devices 3 for detecting, and avoiding continuous use of the level, thereby being capable of timely maintaining the level and avoiding possible bad results. In order to avoid errors after the instrument is used for a long time and whether errors are caused by rotation between the rotating base 20 and the top connecting base 26, the leveling instrument body needs to be checked for levelness after the automatic process is finished, an operator can observe the position of the bubble in the third bubble 21 positioned on the rotating base 20 to perform preliminary checking, then the controller 22 turns on the illuminating lamp 402, at this time, the light generated by the illuminating lamp 402 irradiates the first bubble 404 under the guidance of the first light pipe 403, the bubble positioned in the first bubble 404 projects an amplified image onto the detecting dial 406 under the irradiation of the light, at this time, the operator can determine whether the center of the bubble is positioned at a preset position by observing the corresponding scale where the edge of the bubble projected on the detecting dial 406 is positioned through the observation mirror 401, thereby determining whether the rotating base 20 is positioned in a horizontal state, when the leveling instrument is not in a horizontal state, the automatic leveling function can be suspected to be faulty, if the leveling instrument is to be used continuously, the first angle screw 27 is needed to be used manually to be matched with the horizontal detection device 4 for continuous leveling, if the detection error between the leveling instrument and the automatic leveling instrument is large after the leveling instrument is used for working by a person, the leveling instrument is not recommended to be used continuously, if the automatic leveling function is confirmed to be free of problems through the horizontal detection device 4, the rotating seat 20 is needed to be rotated manually to other angles, the leveling instrument is needed to be used continuously by the horizontal detection device 4 after the rotating is finished, if the rotating seat 20 is rotated to all positions and has no deviation in levelness or the deviation is within a reasonable range, the rotating connection between the rotating seat 20 and the top connection seat 26 can be confirmed to be free of problems, at the moment, the leveling instrument can be used normally, if the rotating seat 20 is at different angles, when larger errors are detected through the level detection device 4, the rotation of the rotating seat 20 can be confirmed to introduce working errors, an automatic leveling function or manual direct leveling is needed after each rotation of the rotating seat 20 to a new observation angle in the subsequent use process, and the leveling instrument body is re-leveled through the calibration of the level detection device 4, so that the measuring accuracy of the device is ensured, and the leveling instrument is also needed to be selected to be abandoned according to whether the errors are in a reasonable range or not to avoid influencing the measurement. When the leveling instrument is confirmed to be leveled and can be used normally, an operator can perform normal measurement operation through the telescope 9, and after measurement is finished or the position of the leveling instrument needs to be transferred, the operator can disengage the tail end of the limiting push rod 10 from the matching with the butt joint seat 13 through the controller 22, then transport the leveling instrument body and the base to the corresponding position after being detached, and then assemble the leveling instrument body again, in the transporting process, the leveling instrument body should be carried by special carrying equipment so as to avoid damage, in the transporting process, the fixing device 6 can be folded upwards, the middle rod 704 can be retracted into the top rod 703, and then the lifting plate 14 is pushed upwards by the adjusting push rod 16 so that the supporting device 7 is stored to the bottom center position of the base 1 as much as possible, so that the leveling instrument is convenient to carry. The leveling instrument designed by the invention can fold the supporting device 7 in a portable manner so as to be convenient to carry, can be fixed on a soft ground by utilizing the fixing device 6, can perform quick horizontal calibration on the base 1 by utilizing the horizontal calibration device 5, can perform automatic leveling by utilizing the auxiliary of the inclination detection device 3, and can also utilize the error in the leveling instrument at the calibration position in time by utilizing the horizontal detection device 4 so as to avoid inappropriate measurement by adopting the leveling instrument with the error, thereby effectively ensuring the precision of construction measurement and having high practical value.
