Description

Technical Field

[0001] The invention relates to the technical field of geological surveying and mapping support components, in particular to a geographic information surveying and mapping instrument for geological surveying. Background Art

[0002] Geological survey refers to the process of systematic, scientific investigation and research on the earth's surface and its internal structure in order to obtain relevant information about the geological distribution, structure and underground resources of rock and soil. During the geological survey, it is necessary to select a suitable geographic information surveying instrument according to the actual situation. A total station is a type of surveying instrument that integrates the functions of angle measurement and distance measurement, and can automatically calculate and display the three-dimensional coordinates of the target point.

[0003] Before using a total station for field measurement, workers need to clear a relatively flat surface and tamp it down, then place the bracket at the bottom of the total station in the designated position and fix it. If the total station is not in a horizontal state during measurement, the measured angle will contain errors caused by the tilt, resulting in inaccurate measurement results. Therefore, the total station needs to be adjusted to a horizontal state before measurement to ensure the accuracy of the measurement results. The existing adjustment method is mostly manual adjustment by workers, which cannot effectively ensure that the total station is in a completely horizontal state, and will have a certain degree of impact on the measurement results. In view of the above problems, there are good solutions in the prior art, such as the total station for geological survey and point mapping with patent number: CN114216022B, which automatically adjusts the mounting plate to a horizontal state by the deadweight of the counterweight box and the cone, and then releases the release switch to energize the excitation coil, and the magnetic powder forms a magnetic powder chain under the action of the magnetic force line, thereby firmly holding the inner and outer rotating shafts and preventing displacement, and installing the fuselage on the mounting plate that has been pre-adjusted to a horizontal state, which greatly simplifies the horizontal adjustment of the fuselage, thereby ensuring work efficiency. However, there are still the following defects: since the total station is leveled by the gravity of the counterweight box, and the wind factor in the field is unstable, when the airflow blows to the surface of the counterweight box exposed in the environment, it will cause the counterweight box to shake, thereby extending the leveling time of the total station, which will still affect work efficiency.

[0004] Therefore, in order to solve the above problems, a geographic information surveying instrument for geological survey is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a geographic information surveying instrument for geological survey, which solves the problem that when the airflow blows to the surface of the counterweight box during the leveling of the total station in the field, the counterweight box will shake, which prolongs the leveling time of the total station and reduces the work efficiency. By setting the main protective cover and the auxiliary protective cover, it is possible to prevent the balance ball and the counterweight ball from shaking due to the influence of wind when the total station is leveled, and it is also possible to limit the balance ball and the counterweight ball when not in use, so as to avoid the balance ball and the counterweight ball from being bumped and worn, thereby ensuring the work efficiency and the accuracy of the measurement results.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A geographic information surveying instrument for geological survey, comprising a total station, a mounting seat, a balancing ball and a counterweight ball connected in sequence, and also comprising a bracket, a main protective sleeve, an electric push rod, an adjustment component and a limit ring, wherein the bracket is arranged below the balancing ball and is sleeved with the counterweight ball, the main protective sleeve is sleeved with the total station, the balancing ball and the counterweight ball, the electric push rod is arranged inside the main protective sleeve, the adjustment component is arranged at the output end of the electric push rod, the limit ring is arranged above the balancing ball and is connected to the adjustment component, when the output end of the electric push rod moves downward, the adjustment component drives the main protective sleeve to be dislocated with the total station and lowers the center of gravity of the bracket, when the electric push rod is at the maximum output length, the adjustment component drives the limit ring to limit the balancing ball, and when the output end of the electric push rod is reset, the adjustment component drives the limit ring to separate from the balancing ball and limit the counterweight ball.

[0008] Preferably, the adjustment assembly includes a fixed frame, a mounting frame, an annular plate, an elastic telescopic rod, a connecting rod 1, a secondary protective sleeve and a connecting rod 2. The fixed frame is arranged on the bracket, the balancing ball is arranged inside the fixed frame, the mounting frame is arranged on the fixed frame, the electric push rod is arranged on the mounting frame and the output end passes through the mounting frame and is connected to the annular plate, the annular plate is sleeved with the fixed frame, the elastic telescopic rod is arranged at the bottom of the annular plate, the lower end of the elastic telescopic rod is arranged in an "L" shape and is connected to the inner wall of the main protective sleeve, the connecting rod 1 is arranged on the annular plate and is connected to the limit ring, the secondary protective sleeve is coaxially arranged below the main protective sleeve, the two ends of the connecting rod 2 are respectively connected to the main protective sleeve and the secondary protective sleeve, the secondary protective sleeve is arranged in a sleeve shape and has a greater gravity than the main protective sleeve.

[0009] It can be seen that there are many ways to fix the counterweight ball, including but not limited to fixing it through an excitation coil. Since the excitation coil needs to be powered on to generate magnetism, during long-term measurements, the excitation coil needs to remain powered on for a long time. Long-term overheating will accelerate the aging of the coil insulation material, reduce its insulation performance, and even burn the coil due to severe heat generation, thereby affecting the fixing effect of the horizontal state of the total station. Therefore, this solution is adopted. After the counterweight ball adjusts the horizontal state of the total station due to its own weight, the balance ball can be fixed by a limit ring to avoid changes in the horizontal state of the total station due to slight vibrations during the measurement process. At the same time, the center of gravity of the entire device can be lowered through the main protective cover and the auxiliary protective cover, making the entire device more stable during the measurement process, effectively ensuring the accuracy of the measurement results.

[0010] Preferably, the bracket includes a support plate, a leg, a screw, an internal threaded ring, a circular ring and a hinged rod, the fixing frame is arranged on the support plate, the leg is hingedly arranged at the bottom of the support plate, a through hole is opened at the bottom of the secondary protective cover, the screw is coaxially arranged with the through hole, the internal threaded ring is threadedly sleeved on the screw, the circular ring is rotatably sleeved on the screw, the two ends of the hinged rod are respectively arranged on the leg and the circular ring, when the total station is working, the bottom of the secondary protective cover is fitted with the top of the internal threaded ring, and the length of the screw is smaller than the length of the secondary protective cover.

[0011] It can be seen that the support height of the existing total station bracket is usually manually adjusted by the staff. However, different support heights of the bracket will lead to different positions of the center of gravity of the bracket, which will also lead to different stability of the bracket during the measurement process. Therefore, this solution is adopted. During each measurement, the legs can be opened at the same angle, so that the distance between the support plate and the bottom of the legs remains constant, thereby ensuring that the center of gravity of the entire device is stable at the same height position during each measurement, and the counterweight ball can be separated from the auxiliary protective cover before the balance ball is limited, so that the total station can be freely adjusted to a horizontal state, thereby avoiding errors in the measurement results due to differences in the stability of the equipment.

[0012] Preferably, the fixing frame includes an annular frame, a U-shaped rod, a fixing rod 1 and a fixing rod 2, two annular frames are provided and connected by the U-shaped rod, balls are provided inside the annular frames, the balancing balls are provided inside the two annular frames and in sliding contact with the balls, the fixing rod 1 and the fixing rod 2 are respectively provided outside the annular frames, the upper end of the fixing rod 1 is connected to the mounting frame, and the lower end of the fixing rod 2 is connected to the internal threaded ring.

[0013] By adopting the above scheme, the distance between the internal thread ring and the support plate can be kept fixed. When the main protective cover moves down to the state before the limit ring contacts the balancing ball and after the auxiliary protective cover is separated from the counterweight ball, the balancing ball can rotate freely under the gravity of the counterweight ball through the friction with the ball bearing, and drive the total station to move during the free rotation. When the counterweight ball is stationary under the action of its own gravity, the total station is in a horizontal state, realizing automatic leveling of the total station. In the process of contacting the protective state of the main protective cover to the total station, the balancing ball and the counterweight ball are both in a protected state, avoiding the deformation of the balancing ball and the counterweight ball due to collision, and effectively ensuring the accuracy of the measurement results after the total station is leveled.

[0014] Preferably, a rubber ring is provided below the limiting ring, the inner wall of the lower end of the rubber ring is concave and matches the outer surface of the balancing ball, and a rubber sleeve is provided inside the secondary protective sleeve, and the rubber sleeve matches the outer surface of the counterweight ball.

[0015] By adopting the above scheme, under the action of the rubber ring and the rubber sleeve, flexible limiting protection for the balancing ball and the counterweight ball can be achieved respectively, avoiding the change of the center of gravity position due to stress friction between the limiting ring and the balancing ball and between the auxiliary protective sleeve and the counterweight ball, thereby ensuring the accurate leveling of the total station and avoiding errors in the measurement results of the total station due to improper equipment calibration.

[0016] Preferably, a plurality of slots are provided at the bottom of the main protective sleeve, and when the upper ends of the slots are in contact with the corresponding legs, the rubber ring fits with the balancing ball.

[0017] By adopting the above scheme, during the measurement process, the main protective cover can limit the position of the support leg through the clamping connection between the clamping slot and the support leg under the action of the electric push rod, avoiding the relative rotation of the screw rod and the internal thread ring. In addition, the protective effect of the secondary protective cover on the counterweight ball can be released (that is, the secondary protective cover is separated from the counterweight ball) during the process of the clamping slot moving down to the clamping connection with the support leg, so that the counterweight ball can adjust the rotation of the balance ball through its own weight, thereby realizing automatic leveling of the total station. As the main protective cover continues to move down, the rubber ring fits with the balance ball to limit the position of the balance ball, ensuring the balance state of the total station, thereby ensuring the measurement results of the total station.

[0018] Preferably, the radial cross-section of the main protective sleeve is arranged to be annular, and when the main protective sleeve is located at the bottom, the weighted ball is located inside the main protective sleeve.

[0019] By adopting the above scheme, the curved surface of the main protective cover can reduce the wind resistance of the entire device when the air flows, thereby ensuring the stability of the entire device and covering the counterweight ball, avoiding the shaking of the counterweight ball caused by air flow during the leveling process, and speeding up the leveling process while ensuring the stability of the total station during use, that is, ensuring work efficiency while also ensuring the accuracy of the total station's measurement results.

[0020] Preferably, the radial cross-section of the secondary protective sleeve is arranged in a ring shape and is coaxially arranged with the main protective sleeve, and the gravity of the secondary protective sleeve is greater than that of the main protective sleeve.

[0021] By adopting the above solution, the influence of wind resistance on the secondary protective cover can be reduced, and the center of gravity height of the entire device can be further lowered after the secondary protective cover is moved down, making the entire device more stable, so that the measurement results do not need to be verified, and the work efficiency is further guaranteed.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. By providing the main protective cover, electric push rod, limit ring and auxiliary protective cover, when in use, after the electric push rod drives the main protective cover to move down to the specified position (the specified position is the state when the card slot opened at the bottom of the main protective cover contacts the corresponding support leg), the counterweight ball can be wrapped around, and in the process of the counterweight ball leveling the total station by its own weight, it can avoid being disturbed by the air flow in the environment, so that the total station can quickly tend to a horizontal state, thereby ensuring work efficiency; and as the output end of the electric push rod continues to move downward, the limit ring can approach the balancing ball along one of the ball center lines of the balancing ball until the rubber ring at the bottom of the limit ring fits with the surface of the balancing ball, thereby fixing the horizontal state of the total station, making the total station in a stable horizontal state, and further ensuring work efficiency.

[0024] 2. By setting up the main protective cover and the auxiliary protective cover, the total station and the balancing ball can be stored inside the main protective cover when not in use, and the counterweight ball can be stored inside the auxiliary protective cover, which avoids the shaking of the counterweight ball and also limits the position of the balancing ball, thereby preventing the balancing ball and the counterweight ball from being bumped and worn due to shaking during the transportation or carrying of the entire device, thereby avoiding the change of the center of gravity of the balancing ball and the counterweight ball, further avoiding the impact on the leveling time of the total station, and ensuring work efficiency.

[0025] 3. By setting up the main protective cover and the auxiliary protective cover, when in use, the main protective cover and the auxiliary protective cover are both at the lowest position, which can lower the center of gravity of the entire device and make the bracket more stable after placement. When the airflow in the environment flows to the outer surface of the main protective cover and the auxiliary protective cover, the arc-shaped surface design of the main protective cover and the auxiliary protective cover can be used to reduce the interference of wind factors on the entire device, avoid shaking of the entire device, ensure the accuracy of the measurement results, and do not need to perform multiple measurements, which also ensures work efficiency.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 8 The present invention provides a geographic information mapping instrument for geological survey, and the technical scheme is as follows:

[0037] For details, please refer to Figure 1 , Figure 2 and Figure 8 A geographic information surveying and mapping instrument for geological survey, comprising a total station 1, a mounting seat 2, a balancing ball 3 and a counterweight ball 4 connected in sequence, and also comprising a bracket 5, a main protective sleeve 6, an electric push rod 7, an adjustment component 8 and a limit ring 9. The bracket 5 is arranged below the balancing ball 3 and is sleeved with the counterweight ball 4. The main protective sleeve 6 is sleeved with the total station 1, the balancing ball 3 and the counterweight ball 4. The electric push rod 7 is arranged inside the main protective sleeve 6. The adjustment component 8 is arranged at the output end of the electric push rod 7. The limit ring 9 is arranged above the balancing ball 3 and is connected to the adjustment component 8. When the output end of the electric push rod 7 moves downward, the adjustment component 8 drives the main protective sleeve 6 to be misaligned with the total station 1 and lowers the center of gravity of the bracket 5. When the electric push rod 7 is at the maximum output length, the adjustment component 8 drives the limit ring 9 to limit the balancing ball 3. When the output end of the electric push rod 7 is reset, the adjustment component 8 drives the limit ring 9 to separate from the balancing ball 3 and limit the counterweight ball 4.

[0038] Under the above setting conditions, when the surveying instrument is not in use, the main protective cover 6 and the adjustment component 8 can protect the total station 1, the balancing ball 3 and the counterweight ball 4 to prevent the total station 1, the balancing ball 3 and the counterweight ball 4 from being bumped during the process of carrying the surveying instrument. When in use, the main protective cover 6 moves downward until the total station 1 is completely exposed, and the balancing ball 3 and the counterweight ball 4 are both inside the main protective cover 6, and the balancing ball 3 can be kept fixed under the limiting effect of the limit ring 9 to avoid shaking. While preventing the balancing ball 3 and the counterweight ball 4 from being exposed, the horizontal angle of the total station 1 can be fixed, which effectively ensures the accuracy of the measurement result.

[0039] As an embodiment of the present invention, refer to Figure 2The adjustment component 8 includes a fixing frame 81, a mounting frame 82, an annular plate 83, an elastic telescopic rod 84, a connecting rod 1 85, a secondary protective sleeve 86 and a connecting rod 2 87. The fixing frame 81 is arranged on the bracket 5, the balancing ball 3 is arranged inside the fixing frame 81, the mounting frame 82 is arranged on the fixing frame 81, the electric push rod 7 is arranged on the mounting frame 82 and the output end passes through the mounting frame 82 and is connected to the annular plate 83, the annular plate 83 is sleeved with the fixing frame 81, the elastic telescopic rod 84 is arranged at the bottom of the annular plate 83, the lower end of the elastic telescopic rod 84 is arranged in an "L" shape and is connected to the inner wall of the main protective sleeve 6, the connecting rod 1 85 is arranged on the annular plate 83 and is connected to the limit ring 9, the secondary protective sleeve 86 is coaxially arranged below the main protective sleeve 6, and the two ends of the connecting rod 2 87 are respectively connected to the main protective sleeve 6 and the secondary protective sleeve 86, and the secondary protective sleeve 86 is arranged in a sleeve shape and has a greater gravity than the main protective sleeve 6.

[0040] Under the above setting conditions, when in use, the electric push rod 7 is started, and the output end of the electric push rod 7 drives the annular plate 83 to move downward. Since the annular plate 83 is connected to the main protective sleeve 6 by the elastic telescopic rod 84, the main protective sleeve 6 can move downward with the annular plate 83. Since the secondary protective sleeve 86 is connected to the main protective sleeve 6 by the connecting rod 2 87, the secondary protective sleeve 86 can be driven to move downward synchronously during the downward movement of the main protective sleeve 6. When the secondary protective sleeve 86 is separated from the counterweight ball 4 and the limit ring 9 has not yet contacted the balancing ball 3, the counterweight ball 4 can freely adjust the angle of the balancing ball 3 under the action of its own gravity, and the total station 1 is connected to the balancing ball 3. During the rotation of the balancing ball 3, the total station 1 can be driven to rotate. The counterweight ball 4 can be assisted manually to quickly reach a stationary state. When the counterweight ball 4 reaches a stationary state, the total station 1 reaches a horizontal state through the action of the balancing ball 3, and continues to start. The electric push rod 7 drives the annular plate 83 to move downward. Since the limit ring 9 is connected to the annular plate 83 by a connecting rod 85, the limit ring 9 can move downward synchronously with the annular plate 83. Since the limit ring 9 is coaxially arranged with the fixing frame 81 and the annular plate 83, and one of the center lines of the balancing ball 3 is colinear with the central axis of the fixing frame 81, the extension line of the central axis of the limit ring 9 passes through the center of the balancing ball 3. When the bottom of the limit ring 9 contacts and squeezes the balancing ball 3, the angle of the balancing ball 3 can be fixed without causing the balancing ball 3 to deflect, that is, the horizontal state of the total station 1 is fixed, thereby effectively ensuring the accuracy of the measurement result of the total station 1, and in the measurement process, due to the downward movement of the main protective cover 6 and the auxiliary protective cover 86, the center of gravity of the entire device can be effectively lowered, thereby effectively ensuring the stability of the entire device, further ensuring the accuracy of the measurement result.

[0041] As an embodiment of the present invention, refer to Figure 3 and Figure 4The bracket 5 includes a support plate 51, a leg 52, a screw 53, an internal threaded ring 54, a ring 55 and a hinged rod 56. The fixing frame 81 is arranged on the support plate 51. The leg 52 is hingedly arranged at the bottom of the support plate 51. A through hole 861 is opened at the bottom of the secondary protective cover 86. The screw 53 is coaxially arranged with the through hole 861. The internal threaded ring 54 is threadedly sleeved on the screw 53. The ring 55 is rotatably sleeved on the screw 53. The two ends of the hinged rod 56 are respectively arranged on the leg 52 and the ring 55. When the total station 1 is working, the bottom of the secondary protective cover 86 is in contact with the top of the internal threaded ring 54. The screw 5 3 is less than the length of the secondary protective sleeve 86. The fixing frame 81 includes an annular frame 811, a U-shaped rod 812, a fixing rod 1 813 and a fixing rod 2 814. Two annular frames 811 are provided and connected by the U-shaped rod 812. Balls 815 are provided inside the annular frames 811. The balancing ball 3 is provided inside the two annular frames 811 and is in sliding contact with the ball 815. The fixing rod 1 813 and the fixing rod 2 814 are respectively provided outside the annular frame 811. The upper end of the fixing rod 1 813 is connected to the mounting frame 82, and the lower end of the fixing rod 2 814 is connected to the internal threaded ring 54.

[0042] Under the above setting conditions, the distance between the internal thread ring 54 and the support plate 51 remains constant. In the process of rotating the screw rod 53, the screw rod 53 and the internal thread ring 54 can be used to move upward. Since the circular ring 55 provided on the screw rod 53 is hinged to the support leg 52 through the hinge rod 56, the support leg 52 can be opened by the circular ring 55 and the hinge rod 56 during the movement on the screw rod 53, and the opening angle of the support leg 52 is limited by the length of the screw rod 53, so that the bracket 5 can be supported in the same stable state during each measurement process. When the top of the circular ring 55 contacts the bottom of the internal thread ring 54, the support leg 52 is opened. 2 is opened to the maximum opening angle. During the synchronous downward movement of the main protective cover 6 and the auxiliary protective cover 86, the balancing ball 3 can rotate freely under the condition of sliding contact with the ball 815 by the gravity of the counterweight ball 4, thereby realizing the automatic adjustment of the horizontal state of the total station 1. At this time, the balancing ball 3 and the counterweight ball 4 are both located inside the main protective cover 6, avoiding the balancing ball 3 and the counterweight ball 4 from being exposed, that is, avoiding the balancing ball 3 and the counterweight ball 4 from being bumped during the measurement process and causing the center of gravity to change, effectively ensuring the accuracy of the leveling result of the balancing ball 3 and the counterweight ball 4 for the total station 1, and further ensuring the accuracy of the measurement result of the total station 1.

[0043] As an embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7A rubber ring 91 is arranged below the limiting ring 9, and the inner wall of the lower end of the rubber ring 91 is concave and matches the outer surface of the balancing ball 3. A rubber sleeve 862 is arranged inside the auxiliary protective sleeve 86, and the rubber sleeve 862 matches the outer surface of the counterweight ball 4.

[0044] Under the above-mentioned setting conditions, when measuring, the secondary protective cover 86 is separated from the counterweight ball 4, and the limiting ring 9 contacts the balancing ball 3 through the rubber ring 91 arranged at the bottom, thereby realizing flexible clamping of the balancing ball 3. In the daily carrying process, the limiting ring 9 is separated from the balancing ball 3, and the secondary protective cover 86 is flexibly connected to the counterweight ball 4 through the internal rubber cover 862, thereby avoiding the wear of the surface of the balancing ball 3 by the limiting ring 9 and the surface of the counterweight ball 4 by the secondary protective cover 86 due to stress, thereby further avoiding the change of the center of gravity position of the balancing ball 3 and the counterweight ball 4, effectively ensuring the accurate leveling of the total station 1 by the balancing ball 3 and the counterweight ball 4, and further ensuring the accuracy of the measurement results of the total station 1.

[0045] As an embodiment of the present invention, refer to Figure 6 and Figure 7 A plurality of slots 61 are provided at the bottom of the main protective sleeve 6. When the upper ends of the slots 61 are in contact with the corresponding legs 52, the rubber ring 91 fits with the balancing ball 3. The radial cross-section of the main protective sleeve 6 is set to be annular. When the main protective sleeve 6 is at the bottom, the counterweight ball 4 is located inside the main protective sleeve 6. The radial cross-section of the secondary protective sleeve 86 is set to be annular and is coaxially arranged with the main protective sleeve 6. The gravity of the secondary protective sleeve 86 is greater than that of the main protective sleeve 6.

[0046] Under the above-mentioned setting conditions, when long-term measurement operations are carried out in the field, the airflow in the environment, after flowing to the surface of the main protective cover 6, can use the arc surface of the main protective cover 6 and the auxiliary protective cover 86 to reduce the wind resistance of the main protective cover 6 and the auxiliary protective cover 86, and under the gravity of the main protective cover 6 and the auxiliary protective cover 86, the center of gravity height of the entire device can be further reduced, thereby increasing the stability of the entire device. At the same time, when the main protective cover 6 moves down to the upper end of the slot 61 and contacts the support leg 52, the counterweight ball 4 is stored inside the main protective cover 6, thereby preventing the air in the environment from blowing toward the counterweight ball 4, effectively shortening the time for the counterweight ball 4 to level the balance ball 3 and the total station 1, thereby ensuring the efficiency of the measurement operation.

[0047] Working principle: In order to make the total station 1 reach a horizontal state as quickly as possible when leveling the total station 1, refer to Figure 1By setting the main protective cover 6, the balancing ball 3 can be wrapped around when the main protective cover 6 moves to the lowest position, so as to avoid the shaking of the counterweight ball 4 caused by the airflow in the environment, shorten the leveling time of the counterweight ball 4 for the total station 1, thereby ensuring the work efficiency; in order to avoid the total station 1, the balancing ball 3 and the counterweight ball 4 from being bumped during the carrying process, refer to Figure 1 , Figure 2 and Figure 8 The main protective cover 6 and the auxiliary protective cover 86 are provided to protect the total station 1, the balancing ball 3 and the counterweight ball 4, so as to prevent the total station 1 from being damaged by collisions, and to prevent the surfaces of the balancing ball 3 and the counterweight ball 4 from being deformed due to collisions, thereby preventing the center of gravity of the balancing ball 3 and the counterweight ball 4 from changing, and ensuring that the total station 1 can be automatically leveled by the balancing ball 3 and the counterweight ball 4 each time it is used, thereby ensuring work efficiency and accuracy of measurement results; in order to ensure the stability of the surveying instrument during measurement operations, reference is made to Figure 1 and Figure 2 Before the measurement operation, the center of gravity of the entire device can be lowered by moving down the main protective cover 6 and the auxiliary protective cover 86, which ensures the stability of the surveying instrument during a single long-term measurement operation in the field. There is no need to verify the measurement results, which further ensures work efficiency.

[0048] Specifically: The present invention includes a used state and an unused state.

[0049] Usage status: Place the whole device at a relatively flat position on the ground, rotate the screw rod 53, and the screw rod 53 moves upward inside the internal threaded ring 54 during the rotation process. The screw rod 53 opens the support leg 52 through the action of the circular ring 55 and the hinged rod 56 during the upward movement, thereby achieving stable placement of the whole device, start the electric push rod 7, and the output end of the electric push rod 7 drives the main protective sleeve 6 to move downward through the annular plate 83 and the elastic telescopic rod 84 until the slot 61 opened at the bottom of the main protective sleeve 6 contacts the support leg 52. At this time, the limit ring 9 and the balancing ball 3, as well as the auxiliary protective sleeve 86 and the counterweight ball 4 are all in a separated state. In this state, the counterweight ball 4 drives the balancing ball 3 to rotate through its own weight, and realizes automatic leveling of the total station 1 under the action of the mounting seat 2 (the leveling process can be manually assisted by the counterweight ball 4 to quickly reach a stationary state). In this process, the balancing ball 3 and the counterweight ball 4 are both inside the main protective sleeve 6, and the outer ring of the main protective sleeve 6 The airflow in the environment will not affect the balancing ball 3 and the counterweight ball 4 when flowing, so that the counterweight ball 4 can complete the leveling of the total station 1 only under the action of its own gravity, which effectively ensures the working efficiency. Due to the retractability of the elastic telescopic rod 84, when the output end of the electric push rod 7 continues to move downward, the annular plate 83 will drive the limit ring 9 to move downward through the connecting rod 1 85, so that the rubber ring 91 at the bottom of the limit ring 9 fits with the balancing ball 3 to limit the balancing ball 3, thereby fixing the horizontal state of the total station 1. At this time, the main protective cover 6 and the auxiliary protective cover 86 are both at the lowest position, which reduces the center of gravity height of the entire device and ensures the stability of the surveying instrument during long-term measurement operations. In addition, when airflow flows in the environment, the main protective cover 6 and the auxiliary protective cover 86 can be designed with arc surfaces to reduce the wind resistance of the main protective cover 6 and the auxiliary protective cover 86, further ensuring the stability of the entire device, without the need to check the measurement results, and further ensuring the working efficiency.

[0050] Unused state: In this state, the secondary protective cover 86 is wrapped around the outside of the counterweight ball 4 to limit the position of the counterweight ball 4, and the total station 1 and the balancing ball 3 are stored inside the main protective cover 6, preventing the total station 1, the balancing ball 3 and the counterweight ball 4 from being bumped during carrying, thereby preventing the total station 1, the balancing ball 3 and the counterweight ball 4 from being damaged (because the horizontal state of the total station 1 depends entirely on the deadweight of the balancing ball 3 and the counterweight ball 4, when the balancing ball 3 and the counterweight ball 4 are scratched or dented on the surface due to bumps, their own center of gravity position will shift, thereby affecting the leveling result of the total station 1), and the diameter of the entire device in the stored state is slightly larger than the diameter of the main protective cover 6, which is convenient for carrying the entire device through the connecting rod 2 87.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
