Description

Technical Field

[0001] This invention relates to the field of surveying and mapping technology, and in particular to a multifunctional surveying and mapping device suitable for complex terrain. Background Technology

[0002] Surveying equipment is an indispensable core device in many fields, including meteorological services, earthquake services, marine meteorological services, surveying services other than satellite application services, other surveying and geographic information services, and mineral geological exploration services using high technology. It is mainly used to collect, process and output the data required by each field. It usually consists of a fixed support and a surveying instrument body. The fixed support undertakes the installation and fixation of the surveying instrument body, which is the foundation for ensuring the stable operation of the above-mentioned service-related measurement work and the accurate acquisition of data.

[0003] The actual surveying and mapping operations related to the aforementioned meteorological services, earthquake services, marine meteorological services, various surveying and mapping services, and mineral geological exploration services are mostly carried out in complex environments such as the field, mountains, sea areas, or construction sites. In order to adapt to complex terrain and ensure the smooth operation of surveying and mapping operations for meteorological services, earthquake services, and other related services, targeted surveying instrument fixing bracket designs have emerged in related technical fields. For example, Chinese Patent No. CN218914419U discloses an anti-tilt surveying instrument fixing bracket for complex terrain. The bracket includes a base plate, and a fixed-length support leg and two adjustable-length variable support legs are fixedly installed on the lower surface of the base plate. The lower ends of the fixed-length support leg and the variable support legs are inclined and extended away from the base plate.

[0004] However, the fixed connection between the two variable legs of the aforementioned fixed bracket and the base plate makes it impossible to adjust the installation angle of the two variable legs, making it difficult to adapt to the diverse and complex terrains that may be encountered in the various service operations. The aforementioned structural defects make it difficult for the fixed bracket to adapt to operation scenarios with large inclination and more complex terrain conditions, resulting in a narrow range of applications and poor flexibility. It cannot meet the surveying and mapping fixed requirements of various services such as meteorological services, earthquake services, and marine meteorological services under diverse and complex terrains. At the same time, considering the problem that dust in the field and construction site environments can easily contaminate the lens and affect the surveying and mapping accuracy, it is necessary to improve the design. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional surveying and mapping device suitable for complex terrain, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a multifunctional surveying device suitable for complex terrain, comprising a ring-shaped frame, telescopic supports arranged in a ring at equal intervals on the outer side of the ring-shaped frame, a limiting mechanism fixedly installed on one side of the ring-shaped frame, and a spherical shell rotatably connected to the inner side of the ring-shaped frame. The inner wall of the ring-shaped frame is in the shape of a concave arc adapted to the outer surface of the spherical shell, and a mounting groove is provided in the middle of the spherical shell. A surveying mechanism is fixedly installed at the bottom of the mounting groove.

[0007] The surveying mechanism includes a lifting module, which is fixedly installed inside the mounting slot. A mounting screw seat is fixedly installed on the top of the lifting module. A surveying instrument is mounted on the top of the lifting module through the mounting screw seat. A transmission module is provided on one side of the front of the surveying instrument. A surveying end cleaning module is rotatably connected to the lower front of the surveying instrument. The surveying end cleaning module includes a turntable, which is rotatably connected to the lower front end of the surveying instrument. A magnetic linkage component is provided on the top of the turntable, and a cleaning plate is fixedly installed on the outer end of the magnetic linkage component. The cleaning end face of the cleaning plate is magnetically attracted and attached to the surface of the surveying end of the surveying instrument.

[0008] Furthermore, the telescopic bracket includes a hinge groove, which is arranged in a ring at equal intervals on the outside of the ring-shaped frame. A hinge wheel is rotatably connected inside the hinge groove, and a telescopic leg is fixedly connected to the outside of the hinge wheel.

[0009] Furthermore, the telescopic bracket includes a main support frame, the outer surface of which is fitted with a support slide tube, the outer end of which is rotatably connected to a hinge ball, the outer end of which is hinged to a support foot plate via the hinge ball, the upper outer end of which is threadedly connected to a limit screw, the head of which is provided with a force-applying shank or knurled pattern, and the end of which penetrates the support slide tube.

[0010] Furthermore, the limiting mechanism includes a side recessed frame, which is fixedly connected to one side of the annular frame. An electric push rod is fixedly installed on the middle of the outer side of the side recessed frame. An anti-slip rubber plate is fixedly installed through the side recessed frame at the output end of the electric push rod. When the electric push rod is extended, the anti-slip rubber plate is in contact with the spherical shell.

[0011] Furthermore, the lifting module includes a mounting sleeve, which is fixedly installed in the middle of the inner side of the mounting groove. A drive motor is fixedly installed at the bottom of the mounting sleeve. A lead screw is rotatably connected inside the mounting sleeve. A slider is threadedly connected to the outer surface of the lead screw. The output end of the drive motor is connected to the bottom end of the lead screw through a coupling. The slider is slidably connected inside the mounting sleeve. A hollow support tube is fixedly installed at the top of the slider. The top of the hollow support tube is connected to the bottom of the mounting screw seat.

[0012] Furthermore, a support frame is fixedly installed on the bottom outer side of the mounting sleeve, and a horizontal load-bearing sphere is fixedly installed on the bottom of the support frame. The horizontal load-bearing sphere is used to provide gravity to make the spherical shell rotate quickly and balance, so as to achieve the efficiency of the surveying instrument to quickly level.

[0013] Furthermore, the cleaning plate can be configured as a cleaning brush or scraper, and the side of the support foot plate away from the hinge ball is fixedly connected with anti-slip conical teeth at equal intervals.

[0014] Furthermore, the transmission module includes a vertical plate and a drive gear. The vertical plate is fixedly installed in one side of the mounting groove. A side bracket is rotatably connected to the rear side of the drive gear. The rear side of the side bracket is fixedly connected to the bottom of the surveying instrument. A rack is fixedly connected to the side of the vertical plate near the drive gear. The rack and the drive gear are meshed together. The drive gear is connected to the magnetic linkage assembly.

[0015] Furthermore, the magnetic linkage assembly includes a rotating shaft, which is fixedly connected to the side of the turntable away from the surveying instrument. A driven gear is fixedly installed on the side of the rotating shaft away from the surveying instrument. The driven gear and the drive gear are meshed together. A hinge is fixedly installed on the top of the rotating shaft. A magnetic suction plate is hinged to the outside of the hinge. The dust removal plate is installed on the top of the magnetic suction plate by screws.

[0016] Furthermore, the magnetic linkage assembly also includes a ring electromagnet and a weighted ball. The weighted ball is fixedly connected to the outer end of the dust removal plate, and the ring electromagnet is fixedly installed on the lower end of the surveying instrument near the drive gear. After the ring electromagnet is energized and generates magnetism, it is magnetically connected to the magnetic plate. A ball bearing is rotatably connected to the rear side of the magnetic plate, and the ball bearing on the magnetic plate is in rolling connection with the ring electromagnet. During use, when the drive motor is running, the ring electromagnet is also energized. At this time, the ring electromagnet generates magnetism, and the magnetic bearing and magnetic plate are attracted. Before this, during the lifting process driven by the drive motor, the shaft will rotate when driven by the rack, drive gear, and transmission gear. At this time, the dust removal plate unfolds... When the annular electromagnet becomes magnetic, it attracts the magnetic plate. The magnetic plate rolls on the annular electromagnet via ball bearings. At this time, the cleaning plate can stably adhere to the surveying end of the surveying instrument for rotation and cleaning. After the height is adjusted, the power to the drive motor and the annular electromagnet is cut off. The annular electromagnet loses power and gravity is provided by the weight ball, which causes the magnetic plate on the cleaning plate to rotate outward at the hinge and open automatically. This prevents the cleaning plate from obstructing the surveying end and affecting the surveying effect. This device has height adjustment and automatic leveling. It can also clean automatically while adjusting the height. After cleaning, it can automatically unfold. The whole device can better adapt to surveying in complex environments.

[0017] Compared with the prior art, the beneficial effects of the present invention are: Firstly, by setting up a telescopic support with multi-dimensional adjustment, the device can adapt to the tilt and unevenness of different complex terrains during use, thus achieving stable installation and improving terrain adaptability and expanding the scope of application. This solves the problem of poor terrain adaptability of fixed supports in the prior art. At the same time, by setting up a horizontal load-bearing sphere and a limiting mechanism, the surveying instrument can be quickly leveled and fixed without cumbersome manual adjustment, thus ensuring the stability of surveying data and solving the problem of inconvenient level adjustment of surveying instruments in complex terrains in the prior art. Secondly, this invention, by setting up a linked lifting module, transmission module, and surveying end cleaning module, allows for automatic cleaning of the surveying end while adjusting the height of the surveying instrument. After cleaning, the dust removal plate automatically opens to avoid obstructing the view, thereby improving the cleanliness of the surveying end and the clarity of the surveyed image, solving the problem of dust adhesion affecting surveying accuracy in existing technologies. Simultaneously, the coordinated operation of these structures simplifies the device setup and debugging process, thereby shortening preparation time and improving overall surveying efficiency.

The head of the limit screw 235 has a force-applying handle or knurled pattern, and the end of the limit screw 235 passes through the support slide tube 232. The combination of the groove 21 and the hinge wheel 22 enables flexible rotation and adjustment of the telescopic tripod 23, adapting to the support angle requirements of different terrains. The combination of the main support frame 231 and the support slide tube 232 allows for free adjustment of the length of the telescopic tripod 23, further improving its adaptability to different terrains. The combination of the hinge ball 233 and the support foot plate 234 allows the support foot plate 234 to conform to ground with different inclinations, enhancing support stability.

Overall, it possesses the core advantages of flexible adjustment, strong adaptability, stable support, and convenient operation, effectively meeting the erection needs of complex terrains.

[0021] Please see Figures 1-5The limiting mechanism 3 includes a side recessed frame 31, which is fixedly connected to one side of the annular frame 1. An electric push rod 32 is fixedly installed on the middle of the outer side of the side recessed frame 31. An anti-slip rubber plate 33 is fixedly installed through the side recessed frame 31 at the output end of the electric push rod 32. When the electric push rod 32 is extended, the anti-slip rubber plate 33 is in contact with the spherical shell 4. By setting the cooperation between the side recessed frame 31 and the electric push rod 32, a stable installation support and power drive can be provided for the limiting and fixing, so as to realize the precise movement of the anti-slip rubber plate 33. By using the cooperation between the electric push rod 32 and the anti-slip rubber plate 33, the anti-slip rubber plate 33 can be tightly attached to the spherical shell 4 when the electric push rod 32 is extended, effectively limiting the rotation of the spherical shell 4 and achieving the effect of firmly locking the horizontal state of the surveying mechanism 6. The whole has the core advantages of reliable locking, convenient operation and accurate positioning, which can ensure the stability of the mechanism posture during the surveying process and avoid the impact of shaking on the surveying accuracy.

[0022] Please see Figures 4-7The lifting module 61 includes a mounting sleeve 611, which is fixedly installed in the middle of the inner side of the mounting groove 5. A drive motor 612 is fixedly installed at the bottom of the mounting sleeve 611. A lead screw 613 is rotatably connected inside the mounting sleeve 611.

A horizontal load-bearing ball 617 is fixedly installed on the bottom of the support frame 616. The horizontal load-bearing ball 617 is used to provide gravity to make the spherical shell 4 rotate quickly and balance, so as to improve the efficiency of the surveying instrument 63 in rapid horizontal measurement. The dust removal plate 653 can be set as a dust removal brush or scraper. Anti-slip conical teeth 236 are fixedly connected at equal intervals on the side of the support foot plate 234 away from the hinge ball 233. The mounting sleeve 611, in conjunction with the drive motor 612 and the lead screw 613, provides a stable mounting base and precise power transmission for lifting and adjusting, enabling the smooth sliding of the slider 614. The lead screw 613, in conjunction with the slider 614, converts the rotational motion of the drive motor 612 into linear motion, causing the hollow support tube 615 and the mounting screw seat 62 to rise and fall synchronously, achieving precise height adjustment of the surveying instrument 63. Furthermore, the support frame 616, in conjunction with the horizontally loaded sphere 617, utilizes gravity to propel the spherical shell... 4. Rapid rotation and balancing enable quick leveling of the surveying instrument 63, improving leveling efficiency; the cleaning plate 653, available in two forms—a brush or a scraper—can adapt to different cleaning needs under varying levels of contamination, ensuring effective cleaning; the combination of support feet 234 and anti-slip conical teeth 236 enhances the adhesion between the support feet 234 and the ground, improving the stability of the device; the overall design possesses core advantages such as precise height adjustment, efficient leveling, strong cleaning adaptability, and stable support, ensuring the accuracy and stability of surveying operations.

[0023] Please see Figures 4-8The transmission module 64 includes a vertical plate 641 and a drive gear 642. The vertical plate 641 is fixedly installed in one side of the mounting groove 5. A side bracket is rotatably connected to the rear side of the drive gear 642. The rear side of the side bracket is fixedly connected to the bottom of the surveying instrument 63. A rack 643 is fixedly connected to the side of the vertical plate 641 near the drive gear 642. The rack 643 and the drive gear 642 are meshed. The drive gear 642 is connected to the magnetic linkage assembly 652. The magnetic linkage assembly 652 includes a rotating shaft 6521. The rotating shaft 6521 is fixedly connected to the side of the turntable 651 away from the surveying instrument 63. A driven gear 6522 is fixedly installed on one side, and the driven gear 6522 meshes with the drive gear 642. A hinge 6523 is fixedly installed on the top of the rotating shaft 6521, and a magnetic suction plate 6524 is hinged to the outside of the hinge 6523. The dust removal plate 653 is installed on the top of the magnetic suction plate 6524 by screws. The magnetic linkage assembly 652 also includes a ring electromagnet 6525 and a weight ball 6526. The weight ball 6526 is fixedly connected to the outer end of the dust removal plate 653. The ring electromagnet 6525 is fixedly installed on the lower end of the surveying instrument 63 near the drive gear 642. After the ring electromagnet 6525 is energized and generates magnetism, it connects with the magnetic field. The magnetic suction plate 6524 is magnetically connected, and a ball bearing is rotatably connected to the rear side of the magnetic suction plate 6524. The ball bearing on the magnetic suction plate 6524 is rollingly connected to the annular electromagnet 6525. By setting the vertical plate 641 in cooperation with the rack 643 and the drive gear 642, the lifting motion of the surveying instrument 63 can be converted into the rotational power of the drive gear 642, providing stable transmission for the cleaning action. The cooperation between the drive gear 642 and the driven gear 6522 can achieve precise power transmission, driving the rotating shaft 6521 to rotate stably. With the cooperation of the rotating shaft 6521, the hinge 6523, and the magnetic suction plate 6524, the cleaning plate 653 can be driven. The device flexibly adjusts its posture to adapt to cleaning needs. Through the cooperation of the annular electromagnet 6525 and the magnetic plate 6524, the cleaning plate 653 can achieve a tight fit with the surveying end when energized, ensuring cleaning effectiveness. The combination of the magnetic plate 6524 and the ball bearing reduces friction during movement, improving the smoothness of the cleaning action. The weighted ball 6526 assists in adjusting the posture of the cleaning plate 653, ensuring smooth avoidance of the surveying field of view after cleaning. Overall, it possesses the core advantages of precise transmission, stable cleaning, smooth action, and flexible posture adjustment, effectively ensuring the cleaning effect of the surveying end and preventing impurities from affecting surveying accuracy.

[0024] The working principle of this invention is as follows: During application, the telescopic bracket 2 achieves initial fixation of the device in complex terrain. The hinge groove 21 provides a rotational basis for the hinge wheel 22, allowing the hinge wheel 22 to drive the telescopic legs 23 to rotate around the annular frame 1, thereby adjusting the angle between each telescopic leg 23 and the annular frame 1. After the angle adjustment is completed, the limiting screw 235 on the outside of the support slide tube 232 is loosened, pushing the support slide tube 232 to slide along the main support frame 231 to adjust the overall length of the telescopic legs 23. After the angle is adjusted to the correct position, tighten the limiting screw 235 in the reverse direction, so that the end of the limiting screw 235 abuts against the main support frame 231, thereby achieving relative fixation between the supporting slide tube 232 and the main support frame 231; by setting the hinge ball 233 to hinge the outer end of the supporting slide tube 232 to the supporting foot plate 234, the supporting foot plate 234 can adapt to the tilt angle of the terrain surface, ensuring that the supporting foot plate 234 is stably attached to the ground. At the same time, the anti-slip conical teeth 236 on the supporting foot plate 234 can embed into the ground, enhancing the friction between the device and the ground; Through the angle and length adjustments of each telescopic tripod 23 and the adaptive fit of the support feet 234, this device can be stably erected on complex terrains with uneven surfaces. After the initial erection of the device, it enters the leveling stage. The surveying instrument 63 is quickly leveled by the cooperation of the spherical shell 4 and the horizontal load-bearing sphere 617. The overall cross-section of the ring frame 1 is arc-shaped, which can provide guidance and limit for the rotation of the spherical shell 4. The outer support frame 616 is used to fix the horizontal load-bearing sphere 617. The horizontal load-bearing sphere 617 utilizes its own... The spherical shell 4 rotates around the inner side of the ring frame 1 due to its own weight, causing the spherical shell 4 to quickly reach a balanced state, thereby driving the surveying mechanism 6 in the mounting groove 5 to achieve horizontal calibration simultaneously. After the horizontal calibration is completed, the electric push rod 32 in the limiting mechanism 3 is activated. The output end of the electric push rod 32 pushes the anti-slip rubber plate 33 to move until the anti-slip rubber plate 33 is tightly attached to the surface of the spherical shell 4. The friction between the anti-slip rubber plate 33 and the spherical shell 4 restricts the rotation of the spherical shell 4, thereby fixing the surveying mechanism 6 in a horizontal state.

[0025] After the horizontal position is fixed, the height adjustment and surveying end cleaning stage begins. The height of the surveying instrument 63 is adjusted via the lifting module 61 according to surveying requirements, while simultaneously completing the automatic cleaning of the surveying end. The mounting sleeve 611 provides a mounting carrier for the drive motor 612, lead screw 613, and slider 614. The support frame 616 provides auxiliary fixation for the mounting sleeve 611. After starting the drive motor 612, its output drives the lead screw 613 to rotate inside the mounting sleeve 611 via a coupling. Because the lead screw 613 is threadedly connected to the slider 614 and the slider 614 is slidably connected to the mounting sleeve 611, therefore… When the lead screw 613 rotates, it drives the slider 614 to slide up and down along the inner wall of the mounting sleeve 611. The hollow support tube 615 at the top of the slider 614 simultaneously drives the mounting screw seat 62 and the surveying instrument 63 to move up and down, thereby adjusting the height of the surveying instrument 63. While the drive motor 612 is running, the annular electromagnet 6525 is energized and generates magnetism. The upright plate 641 is fixed to one side of the mounting groove 5. The rack 643 on the upright plate 641 meshes with the drive gear 642 on the front of the surveying instrument 63. When the surveying instrument 63 moves up and down with the lifting module 61, the drive gear 642 rolls relative to the rack 643, thereby driving the magnet. The driven gear 6522 in the suction linkage assembly 652 rotates. The driven gear 6522 is fixedly connected to the rotating shaft 6521. Therefore, when the driven gear 6522 rotates, it will drive the rotating shaft 6521 to rotate synchronously. The hinge 6523 at the top of the rotating shaft 6521 drives the magnetic suction plate 6524 and the dust removal plate 653 to rotate. The weight ball 6526 at the outer end of the dust removal plate 653 causes the dust removal plate 653 to unfold under the action of gravity. After the annular electromagnet 6525 is energized, it is magnetically connected to the magnetic suction plate 6524, and the ball on the rear side of the magnetic suction plate 6524 is rollingly connected to the annular electromagnet 6525, so that the magnetic suction plate 6524 can move along the annular... The electromagnet 6525 slides stably on its surface, thereby causing the cleaning plate 653 to rotate and scrape against the surface of the surveying end of the measuring instrument 63, achieving automatic cleaning of the surveying end. The cleaning plate 653 can be set as a cleaning brush or a scraper, and the appropriate one can be selected according to the degree of contamination of the surveying end to ensure the cleaning effect. The annular electromagnet 6525 is arranged in a ring shape, so when the magnetic plate 6524 rotates to the bottom, it can be attracted to the annular electromagnet 6525, thus ensuring its adhesion and cleaning performance during the lifting and lowering process. After the power is turned off, the weight ball 6526 provides gravity, which can cause the cleaning plate 653 to automatically separate.

[0026] Finally, the surveying operation phase begins. After the surveying instrument 63 has been height-adjusted and the surveying end has been cleaned, the power to the drive motor 612 and the annular electromagnet 6525 is cut off. Once the annular electromagnet 6525 loses its magnetism, the weighted ball 6526, under the influence of gravity, drives the magnetic plate 6524 to rotate outward around the hinge 6523, moving the cleaning plate 653 away from the surveying end of the surveying instrument 63 to avoid obstructing the surveying view. The surveying instrument 63 is then activated, completing surveying data collection for meteorological services, earthquake services, marine meteorological services, surveying services other than satellite applications, other surveying and geographic information services, and mineral geological exploration services using advanced technology. This technical solution, through the multi-dimensional adjustment structure of the telescopic support 2, significantly improves the adaptability to complex terrain, expands the scope of application, and solves the problem of poor terrain adaptability of fixed supports in existing technologies. The horizontal weighted ball 617 allows the device to quickly level the surveying instrument 63 without tedious manual adjustments. The high precision of the measuring instrument 63, combined with the rapid fixing function of the limiting mechanism 3, ensures that the instrument remains horizontal in complex terrain, guaranteeing the stability of the surveying data. Through the coordinated operation of the surveying end cleaning module 65, transmission module 64, and lifting module 61, automatic cleaning is completed while adjusting the height of the measuring instrument 63, eliminating the need for manual cleaning or additional cleaning steps. This effectively solves the problem of dust accumulation affecting surveying accuracy, ensuring the cleanliness of the surveying end, improving the clarity of the surveyed image, and thus guaranteeing the accuracy of the surveying data. The automatic opening design of the dust removal plate 653 further ensures the integrity of the surveying field of view, ensuring the smooth progress of surveying work. This technical solution simplifies the setup and debugging process of the device through the coordinated cooperation of various structures, shortens the preparation time, and improves the overall efficiency of surveying operations. Furthermore, with its stable structural design and precise surveying data acquisition capabilities, it can meet the surveying needs of multiple fields, ensuring the smooth conduct of surveying operations in various fields and improving the accuracy of service assessments in each field.
