Description

Technical Field

[0001] This invention belongs to the field of total station support technology, specifically relating to a multi-terrain, multi-functional total station support. Background Technology

[0002] A total station, also known as a total station electronic tachometer, is an instrument that, once observed at a station, automatically displays necessary observation data such as slope distance, zenith distance, and horizontal angle. It also provides horizontal distance, elevation difference, and point coordinates almost simultaneously. By connecting the data terminal of the total station's field data collection to a computer or plotter via a transmission interface, and using data processing and plotting software, automated mapping can be achieved. Total stations are widely used in precision engineering surveying or deformation monitoring fields such as large-scale above-ground construction and underground tunnel construction. To ensure stability and accuracy, they are typically supported by a tripod. A total station tripod mainly consists of three extendable legs, each equipped with an adjustment knob. Height and level are adjusted manually by rotating these knobs.

[0003] Existing total station tripods typically use a fixed pointed or rounded design at the bottom, which requires tools to remove bolts or clips, making the operation cumbersome and time-consuming. This makes it difficult to quickly adapt to different terrains. Since total stations are directly exposed to the outside, they can only stop monitoring when in environments such as rain, snow, sandstorms, fog, or strong winds, relying on the instrument lens's own dustproof and waterproof technology for protection, thus affecting continuous operation.

[0004] Therefore, there is an urgent need to provide a multi-terrain, multi-functional support for total stations to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-terrain and multi-functional support for total station.

[0006] The technical solution adopted to solve the above technical problems is: a multi-terrain and multi-functional support for a total station, including a support mounting base, a protective cover mounting base attached to the top of the support mounting base, and a total station body attached to the top of the protective cover mounting base. The bottom end of the total station body is fixed with a mounting base threaded cylinder that extends through and into the inside of the bracket mounting base. A fixing bolt that extends through and into the inside of the mounting base threaded cylinder is installed in the internal thread of the bracket mounting base. The bottom of the bracket mounting base is provided with an adjustment mechanism for adjusting the height of the bracket, and the interior of the adjustment mechanism is provided with a switching mechanism that can change the ground contact mode according to the survey site. The top of the protective cover mounting base is equipped with a protective mechanism to enhance the production capacity of the total station in harsh environments. The interior of the protective mechanism is equipped with an opening and closing mechanism to realize the opening and closing of the protective mechanism. The top of the opening and closing mechanism is equipped with a sunshade mechanism that can effectively block direct sunlight, and the outside of the protective mechanism is equipped with a locking mechanism for locking the current working state of the opening and closing mechanism.

[0007] Using the above technical solution, the protective cover mounting seat is first placed on the mounting seat threaded cylinder at the bottom of the total station body. Then, the mounting seat threaded cylinder is fitted into the slot of the bracket mounting seat. The fixing bolt is rotated by hand to fix the fixing bolt to the mounting seat threaded cylinder, thereby assembling the bracket mounting seat, the protective cover mounting seat, and the total station body together.

[0008] Furthermore, the adjustment mechanism includes three mounting slide rods rotatably mounted on the bottom of the bracket mounting base. One end of each of the three mounting slide rods is fixed with a slide rod limiting seat, and a positioning sleeve is slidably mounted on the outside of each of the three mounting slide rods.

[0009] With the above technical solution, the three mounting slide rods are arranged in a triangle, and their angles can be adjusted via the bracket mounting seat, thereby achieving multi-directional adjustment of the equipment installation position. The positioning slide sleeve can move stably on the mounting slide rods so as to adjust the position of the equipment according to actual needs. The slide rod limit seat is used to limit the movement range of the positioning slide sleeve, prevent it from detaching from the mounting slide rods, and ensure the safety and reliability of the entire adjustment process.

[0010] Furthermore, one end of the positioning sleeve is fixed with a sleeve telescopic plate that penetrates and extends to the outside of the slide rod limiting seat, a rubber plate is fixed on one side of the sleeve telescopic plate, and a hand-tightening bolt is installed in the internal thread of the slide rod limiting seat.

[0011] Through the above technical solution, the sliding sleeve telescopic plate is length-adjusted by positioning the sliding sleeve, which increases the adaptability and flexibility of the equipment support. The adjusted sliding sleeve telescopic plate is fixed by rotating the hand-tightening bolt. The sliding sleeve telescopic plate increases the friction between the hand-tightening bolt and the sliding sleeve telescopic plate, improving the firmness of the fixation and ensuring that the equipment will not be displaced by external forces during use.

[0012] Furthermore, the switching mechanism includes a rotating seat rotatably mounted on one end of the sliding sleeve telescopic plate. One end of the rotating seat is fixed with a bracket tip, and the other end of the rotating seat is fixed with a bracket round head. A bracket pedal is fixed to one side of both the bracket tip and the bracket round head.

[0013] Through the above technical solution, the rotating seat can be flipped by the sliding sleeve telescopic plate, thereby switching between the pointed head and the round head of the bracket. The bracket pedals of the pointed head and the round head of the bracket are convenient for the operator to step on.

[0014] Furthermore, a cylindrical spring is fixed inside the sliding sleeve telescopic plate, a spring extension rod is fixed to one end of the cylindrical spring, and a pedal fixing cylinder is fixed to one end of the spring extension rod and slidably connected to the sliding sleeve telescopic plate. The inside of the pedal fixing cylinder is fitted and connected to the outside of the bracket pedal.

[0015] With the above technical solution, when the bracket tip is needed, the pedal fixing cylinder is manually pushed up, causing the rotating seat to rotate around the sliding sleeve telescopic plate until the bracket tip is in the required working position. The pedal fixing cylinder is then released, and the cylindrical spring drives the spring extension rod and the pedal fixing cylinder to extend, so that the pedal fixing cylinder fits over the outside of the bracket pedal, limiting and fixing the bracket pedal. This allows for the selective fixing of the bracket tip and the bracket round head of the rotating seat. Similarly, when the bracket round head is needed, the pedal fixing cylinder is manually pushed up, causing the rotating seat to rotate around the sliding sleeve telescopic plate until the bracket tip is in the required working position. The pedal fixing cylinder is then released, and the cylindrical spring drives the spring extension rod and the pedal fixing cylinder to extend, so that the pedal fixing cylinder fits over the outside of the bracket pedal, limiting and fixing the bracket pedal. This allows for the selective fixing of the bracket tip and the bracket round head of the rotating seat.

[0016] Furthermore, the protective mechanism includes a protective shell that is slidably mounted on the top of the protective cover mounting base. A first guide rail ring is fixed to the outside of the protective cover mounting base. The inside of the first guide rail ring is rotatably connected to the bottom end of the protective shell. An installation cylinder is fixed to the middle of the inner top wall of the protective shell. A total station handle connecting frame is fitted into the bottom end of the installation cylinder. A connecting frame bolt with one end penetrating through and extending into the inside of the total station handle connecting frame is threaded onto one side of the installation cylinder.

[0017] Through the above technical solution, the total station handle connecting frame is aligned with the bottom end of the mounting cylinder and fitted into place. Then, it is tightened and fixed using the connecting frame bolts. The protective shell is rotated and adjusted via the first guide rail ring. The protective shell is connected to the handle at the top of the total station body via the mounting cylinder and the total station handle connecting frame, allowing the protective shell to rotate in sync with the angle adjustment of the total station body. Throughout the measurement process, as the total station body continuously adjusts its angle to measure data in different directions, the protective shell will rotate synchronously by the corresponding angle under the constraint of the first guide rail ring, always covering the critical parts of the total station to provide protection.

[0018] Furthermore, the opening and closing mechanism includes a first opening and closing rotating cylinder rotatably installed inside the protective shell, a second opening and closing rotating cylinder rotatably installed on one side of the first opening and closing rotating cylinder, a second guide rail ring fixed at the top of the protective cover mounting base, and the interior of the second guide rail ring slidably connected to the bottom ends of the first opening and closing rotating cylinder and the second opening and closing rotating cylinder.

[0019] Through the above technical solution, the first and second opening and closing rotating drums can rotate stably via the second guide ring.

[0020] Furthermore, a cylindrical sleeve shaft is fixed to the top of the first opening and closing rotating cylinder and is rotatably connected to the mounting cylinder. A first bevel gear is fixed to the top of the cylindrical sleeve shaft, and a second bevel gear is fixed to the top of the second opening and closing rotating cylinder. A connecting bevel gear is rotatably installed on one side of the inner top wall of the protective shell. The outer side of the connecting bevel gear meshes with the first bevel gear and the second bevel gear respectively.

[0021] With the above technical solution, when opening and closing the opening of the protective shell, the first opening and closing drum is manually rotated. The first opening and closing drum drives the cylindrical sleeve shaft and the first bevel gear to rotate accordingly. The first bevel gear drives the second bevel gear to rotate in the opposite direction through the connecting bevel gear. The second bevel gear drives the second opening and closing drum to rotate accordingly, so that the first opening and closing drum and the second opening and closing drum cooperate to open and close the opening of the protective shell.

[0022] Furthermore, the sunshade mechanism includes two sunshade telescopic plates slidably installed between the two side walls of the inner cavity of the protective shell. The bottom ends of the two sunshade telescopic plates are fixed with telescopic racks. A mounting pinion is rotatably installed on the other side of the inner top wall of the protective shell. The outer surface of the mounting pinion meshes with the two telescopic racks respectively. A mounting large gear is fixed to the top of the first bevel gear, and the mounting large gear meshes with the mounting pinion.

[0023] Through the above technical solution, the first bevel gear will drive the large mounting gear to rotate, the large mounting gear will drive the small mounting gear to rotate, and the small mounting gear will drive the two telescopic racks to move to opposite sides. The two telescopic racks will drive the two sunshade telescopic plates to move to the outside of the protective shell, covering the top of the opening of the protective shell and preventing sunlight from shining directly on the equipment below.

[0024] Furthermore, the locking mechanism includes four spring mounting cylinders fixed to the outside of the protective shell. Each of the four spring mounting cylinders has a telescopic spring fixed inside. Each of the four telescopic springs has a spring telescopic rod fixed to one end. The bottom end of each of the four spring telescopic rods is fixed with a limiting ring. One side of the first opening and closing rotating cylinder and the second opening and closing rotating cylinder are both fixed with a limiting block. The bottom end of the limiting ring is provided with a limiting groove that matches the limiting block.

[0025] With the above technical solution, the limiting ring is manually pulled upward, allowing the first and second opening and closing rotating cylinders to rotate freely. When the first and second opening and closing rotating cylinders open and close the opening of the protective shell, the telescopic spring drives the limiting ring downward through the spring telescopic rod, so that the limiting ring effectively locks the limiting blocks of the first and second opening and closing rotating cylinders through the limiting slot.

[0026] The beneficial effects of this invention are as follows: (1) By providing a protective mechanism and an opening and closing mechanism, the present invention can form a relatively closed space, effectively blocking moisture, dust and other particulate matter in the external environment from continuously disturbing the instrument, reducing the damage to the total station in environments such as rain, snow, sand, fog and strong wind, significantly improving the protection capability of the total station in harsh environments, and extending the service life of the instrument. The opening and closing mechanism adopts a rotating sliding design, and users can easily open and close the protective mechanism through simple push and pull actions. When observation is needed, the opening and closing mechanism is opened, and when not in use, the opening and closing mechanism is closed to provide protection. The protective mechanism and the opening and closing mechanism can rotate together when the total station rotates, ensuring the continuity and accuracy of the measurement operation and avoiding affecting the normal operation of the total station. (2) By providing an adjustment mechanism and a switching mechanism, the present invention can determine the ground contact mode to be used according to the general terrain of the surveying site. If there is a lot of hard ground, the pointed head mode is preferred. If the ground is mainly soft, the round head mode is considered. No additional tools or cumbersome operations are required, which effectively saves time and improves work efficiency. If the height of the support needs to be adjusted, loosen the locking bolt, then hold the knob and rotate it clockwise or counterclockwise, observe the height change of each leg until it reaches the appropriate position, and then tighten the locking bolt to fix the height. This allows the support to easily cope with various terrain undulations. Whether it is a hillside or a depression, it can ensure that the surveying equipment is in a horizontal state, which improves the reliability of the measurement data. (3) The present invention is provided with an opening and closing mechanism, a sunshade mechanism and a locking mechanism. The sunshade mechanism is connected to the opening and closing mechanism. When the opening and closing mechanism is opened, the sunshade mechanism extends and unfolds accordingly. When closed, it retracts to the initial position. The sunshade mechanism can effectively block direct sunlight and reduce heat absorption. The locking mechanism is used to lock the current open or closed working state of the opening and closing mechanism. It can be quickly switched through simple operation and ensures that it will not easily loosen during use. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figures 1-11As shown, this embodiment of a multi-terrain, multi-functional total station support includes a support mounting base 1, a protective cover mounting base 2 attached to the top of the support mounting base 1, and a total station body 3 attached to the top of the protective cover mounting base 2. A mounting base threaded cylinder 4, with one end penetrating and extending into the support mounting base 1, is fixed to the bottom end of the total station body 3. A fixing bolt 5, with one end penetrating and extending into the mounting base threaded cylinder 4, is threaded into the internal part of the support mounting base 1. An adjustment mechanism 6 for adjusting the height of the support is provided at the bottom end of the support mounting base 1. The adjustment mechanism 6 includes components rotatably mounted on the support mounting base 1. Three mounting slide rod brackets 601 are located at the bottom. Each of the three mounting slide rod brackets 601 has a slide rod limiting seat 602 fixed to one end. A positioning sleeve 603 is slidably mounted on the outside of each of the three mounting slide rod brackets 601. A sleeve telescopic plate 604, penetrating and extending to the outside of the slide rod limiting seat 602, is fixed to one end of the sleeve telescopic plate 604. A rubber plate 605 is fixed to one side of the sleeve telescopic plate 604. A hand-tightening bolt 606 is installed in the internal thread of the slide rod limiting seat 602. First, the protective cover mounting seat 2 is fitted onto the mounting seat threaded cylinder 4 at the bottom of the total station body 3. Then, the mounting seat thread... The cylinder 4 is fitted into the slot of the bracket mounting base 1. The fixing bolt 5 is rotated by hand to secure it to the threaded cylinder 4 of the mounting base. This assembles the bracket mounting base 1, the protective cover mounting base 2, and the total station body 3 together. The three mounting slide rod brackets 601 at the bottom of the bracket mounting base 1 are arranged in a triangle, allowing for angle adjustment via the bracket mounting base 1, thus enabling multi-directional adjustment of the equipment's installation position. The positioning slide sleeve 603 can move stably on the mounting slide rod bracket 601 to adjust the equipment's position according to actual needs. The slide rod limit seat 602 is used for... To limit the movement range of the positioning sleeve 603 and prevent it from detaching from the mounting slide bracket 601, ensuring the safety and reliability of the entire adjustment process, the sliding sleeve telescopic plate 604 is length-adjusted via the positioning sleeve 603, increasing the adaptability and flexibility of the equipment support. The hand-tightening bolt 606 is rotated by hand to fix the adjusted sliding sleeve telescopic plate 604. The sliding sleeve telescopic plate 604 increases the friction between the hand-tightening bolt 606 and the sliding sleeve telescopic plate 604, improving the firmness of the fixation and ensuring that the equipment will not be displaced by external forces during use.

[0031] like Figure 4 and Figure 5As shown, the adjustment mechanism 6 is internally equipped with a switching mechanism 7 that can change the ground contact mode according to the survey site. The switching mechanism 7 includes a rotating seat 701 rotatably mounted on one end of the sliding sleeve telescopic plate 604. One end of the rotating seat 701 is fixed with a bracket tip 702, and the other end of the rotating seat 701 is fixed with a bracket round head 703. A bracket pedal 704 is fixed to one side of both the bracket tip 702 and the bracket round head 703. A cylindrical spring 705 is fixed inside the sliding sleeve telescopic plate 604. One end of the cylindrical spring 705 is fixed with a spring extension rod 706, and one end of the spring extension rod 706 is fixed with a pedal fixing cylinder 707 that is slidably connected to the sliding sleeve telescopic plate 604. The inside of the pedal fixing cylinder 707 is fitted and connected to the outside of the bracket pedal 704. When the bracket tip 702 needs to be used, the pedal fixing cylinder 707 is manually pushed up, causing the rotating seat 701 to rotate around the sliding sleeve telescopic plate 604 to the bracket tip 702. 2. When the pedal fixing cylinder 707 is in the desired working position, the cylindrical spring 705 drives the spring extension rod 706 and the pedal fixing cylinder 707 to extend, so that the pedal fixing cylinder 707 is fitted over the support pedal 704, limiting and fixing the support pedal 704. This allows for the selection and fixing of the support tip 702 and the support round head 703 of the rotating seat 701. Similarly, when the support round head 703 needs to be used, the pedal fixing cylinder 707 is manually pushed up, causing the rotating seat 701 to rotate around the sliding sleeve telescopic plate 604 until the support tip 702 is in the desired working position. The pedal fixing cylinder 707 is then released, and the cylindrical spring 705 drives the spring extension rod 706 and the pedal fixing cylinder 707 to extend, so that the pedal fixing cylinder 707 is fitted over the support pedal 704, limiting and fixing the support pedal 704. This allows for the selection and fixing of the support tip 702 and the support round head 703 of the rotating seat 701.

[0032] like Figures 6-8As shown, the top of the protective cover mounting base 2 is equipped with a protective mechanism 8 to enhance the production capacity of the total station in harsh environments. The protective mechanism 8 includes a protective shell 801 slidably mounted on the top of the protective cover mounting base 2. A first guide rail ring 802 is fixed to the outside of the protective cover mounting base 2. The inside of the first guide rail ring 802 is rotatably connected to the bottom end of the protective shell 801. A mounting cylinder 803 is fixed to the middle of the inner top wall of the protective shell 801. A total station grip connecting frame 804 is fitted into the bottom end of the mounting cylinder 803. A connecting frame bolt 805 is threaded on one side of the mounting cylinder 803, with one end penetrating and extending into the total station grip connecting frame 804. The total station grip connecting frame 804... The bottom end of the mounting cylinder 803 is fitted and installed, and then it is tightened and fixed using the connecting bracket bolt 805. The protective shell 801 is rotated and adjusted by the first guide rail ring 802. The protective shell 801 is connected to the handle at the top of the total station body 3 through the mounting cylinder 803 and the total station handle connecting bracket 804, so that the protective shell 801 can rotate with the angle adjustment of the total station body 3. During the entire measurement process, as the total station body 3 continuously adjusts its angle to measure data in different directions, the protective shell 801 will rotate synchronously with the corresponding angle under the constraint of the first guide rail ring 802, always covering the key parts of the total station to play a protective role.

[0033] like Figures 6-10 As shown, the protective mechanism 8 is internally equipped with an opening and closing mechanism 9 for opening and closing the protective mechanism 8. The opening and closing mechanism 9 includes a first opening and closing rotary cylinder 901 rotatably mounted inside the protective shell 801, a second opening and closing rotary cylinder 902 rotatably mounted on one side of the first opening and closing rotary cylinder 901, a second guide rail ring 903 fixed to the top of the protective cover mounting base 2, the interior of the second guide rail ring 903 being slidably connected to the bottom ends of the first opening and closing rotary cylinder 901 and the second opening and closing rotary cylinder 902, a cylindrical sleeve shaft 904 rotatably connected to the mounting cylinder 803 fixed to the top of the first opening and closing rotary cylinder 901, a first bevel gear 905 fixed to the top of the cylindrical sleeve shaft 904, a second bevel gear 906 fixed to the top of the second opening and closing rotary cylinder 902, and a rotating part of the inner top wall of the protective shell 801. A connecting bevel gear 907 is installed, and the outside of the connecting bevel gear 907 meshes with the first bevel gear 905 and the second bevel gear 906 respectively. The first opening and closing rotating drum 901 and the second opening and closing rotating drum 902 can rotate stably through the second guide ring 903. When opening and closing the opening of the protective shell 801, the first opening and closing rotating drum 901 is manually rotated. The first opening and closing rotating drum 901 drives the cylindrical sleeve shaft 904 and the first bevel gear 905 to rotate accordingly. The first bevel gear 905 drives the second bevel gear 906 to rotate in the opposite direction through the connecting bevel gear 907. The second bevel gear 906 drives the second opening and closing rotating drum 902 to rotate accordingly, so that the first opening and closing rotating drum 901 and the second opening and closing rotating drum 902 cooperate to open and close the opening of the protective shell 801.

[0034] like Figure 7 and Figure 10 As shown, the top of the opening and closing mechanism 9 is provided with a sunshade mechanism 10 that can effectively block direct sunlight. The sunshade mechanism 10 includes two sunshade telescopic plates 1001 that are slidably installed between the two side walls of the inner cavity of the protective shell 801. The bottom ends of the two sunshade telescopic plates 1001 are fixed with telescopic racks 1002. A mounting pinion 1003 is rotatably installed on the other side of the inner top wall of the protective shell 801. The outer surface of the mounting pinion 1003 meshes with the two telescopic racks 1002 respectively. The top of the first bevel gear 905 is fixed with a mounting large gear 10. 04. When the large gear 1004 and the small gear 1003 mesh, the first bevel gear 905 will drive the large gear 1004 to rotate. The large gear 1004 will drive the small gear 1003 to rotate. The small gear 1003 will drive the two telescopic racks 1002 to move to opposite sides. The two telescopic racks 1002 will drive the two sunshade telescopic plates 1001 to move to the outside of the protective shell 801, covering the top of the opening of the protective shell 801 to prevent sunlight from shining directly on the equipment below.

[0035] like Figure 6 and Figure 11 As shown, the protective mechanism 8 is externally provided with a locking mechanism 11 for locking the current working state of the opening and closing mechanism 9. The locking mechanism 11 includes four spring mounting cylinders 1101 fixed to the outside of the protective shell 801. Each of the four spring mounting cylinders 1101 has a telescopic spring 1102 fixed inside. Each of the four telescopic springs 1102 has a spring telescopic rod 1103 fixed to one end. The bottom end of each of the four spring telescopic rods 1103 is fixed with a limit ring 1104. A limit block 1105 is fixed to one side of both the first opening and closing rotating cylinder 901 and the second opening and closing rotating cylinder 902. The limit ring 1104 The bottom end is provided with a limiting groove that matches the limiting block 1105. The limiting ring 1104 is manually pulled upward, so that the first opening and closing rotating cylinder 901 and the second opening and closing rotating cylinder 902 can rotate freely. When the first opening and closing rotating cylinder 901 and the second opening and closing rotating cylinder 902 open and close the opening of the protective shell 801, the telescopic spring 1102 drives the limiting ring 1104 to move downward through the spring telescopic rod 1103, so that the limiting ring 1104 effectively locks the limiting block 1105 of the first opening and closing rotating cylinder 901 and the second opening and closing rotating cylinder 902 through the limiting groove.

[0036] The working principle of this embodiment is as follows: When using the total station body 3 for surveying, first, the protective cover mounting base 2 is placed on the mounting base threaded cylinder 4 at the bottom of the total station body 3. Then, the mounting base threaded cylinder 4 is fitted into the slot of the bracket mounting base 1. The fixing bolt 5 is rotated by hand to make the fixing bolt 5 threadedly fixed with the mounting base threaded cylinder 4, thereby assembling the bracket mounting base 1, the protective cover mounting base 2, and the total station body 3 together. When the bracket tip 702 needs to be used, the pedal fixing cylinder 707 is manually pushed up, causing the rotating base 701 to rotate around the sliding sleeve telescopic plate 604 until the bracket tip 702 is in the required working position. The pedal fixing cylinder 707 is released, and the cylindrical spring 705 drives the spring extension rod 706 and the pedal fixing cylinder 707. The pedal fixing cylinder 707 is extended so that it fits over the support pedal 704, limiting and fixing the support pedal 704. This, in turn, allows for selective fixing of the support tip 702 and support round head 703 of the rotating seat 701. Similarly, when the support round head 703 is needed, the pedal fixing cylinder 707 is manually pushed up, causing the rotating seat 701 to rotate around the sliding sleeve telescopic plate 604 until the support tip 702 is in the desired working position. Releasing the pedal fixing cylinder 707 causes the cylindrical spring 705 to drive the spring extension rod 706 and the pedal fixing cylinder 707 to extend, so that the pedal fixing cylinder 707 fits over the support pedal 704, limiting and fixing the support pedal 704. This, in turn, allows for selective fixing of the support tip 702 and support round head 703 of the rotating seat 701. 3. The three mounting slide rod brackets 601 at the bottom of the bracket mounting base 1 are arranged in a triangle, allowing for angle adjustment via the bracket mounting base 1. This enables multi-directional adjustment of the equipment installation position. The positioning slide sleeve 603 can move stably on the mounting slide rod bracket 601 to adjust the equipment position according to actual needs. The slide rod limit seat 602 limits the movement range of the positioning slide sleeve 603, preventing it from detaching from the mounting slide rod bracket 601 and ensuring the safety and reliability of the entire adjustment process. The slide sleeve telescopic plate 604 is length-adjusted via the positioning slide sleeve 603, increasing the adaptability and flexibility of the equipment bracket. The hand-tightening bolt 606 is used to fix the adjusted slide sleeve telescopic plate 604. The telescopic plate 604 increases the friction between the hand-tightened bolt 606 and the sliding telescopic plate 604, improving the stability of the fixation and ensuring that the equipment will not shift due to external forces during use. The total station handle connecting frame 804 is aligned with the bottom end of the mounting cylinder 803 and fitted in place, then tightened and fixed using the connecting frame bolt 805. The protective shell 801 is rotated and adjusted via the first guide ring 802. The protective shell 801 is connected to the handle at the top of the total station body 3 via the mounting cylinder 803 and the total station handle connecting frame 804, allowing the protective shell 801 to rotate with the angle adjustment of the total station body 3. Throughout the measurement process, as the total station body 3 continuously adjusts its angle to measure data in different directions, the protective shell 801 can rotate accordingly.The protective shell 801 rotates synchronously by a corresponding angle under the constraint of the first guide ring 802, always covering the key parts of the total station for protection. In the event of rain, snow, sandstorms, heavy fog, or strong winds, the limiting ring 1104 can be manually pulled upwards, allowing the first and second opening and closing cylinders 901 and 902 to rotate freely. Manually rotating the first opening and closing cylinder 901 drives the cylindrical sleeve shaft 904 and the first bevel gear 905 to rotate accordingly. The first bevel gear 905, through the connecting bevel gear 907, drives the second bevel gear 906 to rotate in the opposite direction. The second bevel gear 906 then drives the second opening and closing cylinder 902 to rotate accordingly, so that the first and second opening and closing cylinders 901 and 902 cooperate to close the opening of the protective shell 801. When the device closes, the first bevel gear 905 drives the large mounting gear 1004 to rotate, which in turn drives the small mounting gear 1003 to rotate. The small mounting gear 1003 then moves the two telescopic racks 1002 to opposite sides, causing the two telescopic sunshade panels 1001 to retract into the protective shell 801. Once the first and second opening / closing cylinders 901 and 902 close the opening of the protective shell 801, the telescopic spring 1102 drives the limiting ring 1104 downwards via the spring telescopic rod 1103. This allows the limiting ring 1104 to effectively lock the limiting blocks 1105 of the first and second opening / closing cylinders 901 and 902 through the limiting slots, preventing continuous damage from moisture and dust to the total station.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
