Description

Technical Field

[0001] This invention relates to the field of surveying and mapping engineering technology, specifically to a protective surveying and mapping device for surveying and mapping engineering that is adaptable to multiple environments. Background Technology

[0002] In surveying engineering, the stability of the surveying instrument is controlled by the combination of the set support device and the surveying instrument. In order to improve the safety of the surveying instrument during operation, a protective mechanism is used to control the safety of the surveying device and effectively improve the all-round protection capability. However, during use, it is inconvenient to control the safety when the instrument is placed, which can easily lead to the surveying instrument tipping over and being damaged.

[0003] To overcome the aforementioned shortcomings, the existing technology (Chinese patent application CN202121997338.0, filed on August 18, 2021) provides a surveying engineering auxiliary surveying device. Through a structural design comprising a main board, baffle, spring, limiting sleeve, clamping block, panel, surveying instrument body, mounting block, wrist strap, opening, strap, Velcro, and adhesive tape, it achieves a convenient wrist-worn design, solving the problem of difficulty in gripping. The wrist-worn design of the surveying device is more portable, provides better stability, and avoids damage to the surveying process due to the operator's inability to grip securely. The probability of the instrument slipping and breaking is reduced, meeting people's needs and bringing convenience to their work; there is also existing technology (Chinese patent application No. CN202420450694.8, application date March 8, 2024) of a surveying engineering auxiliary surveying device, which, through the setting of an automatic sunshade, rotating rod, positioning rod and first spring, when performing engineering surveying operations with an RTK surveying instrument, the handle of the automatic sunshade is screwed to one end of the rotating rod in advance. When encountering hot or rainy weather during the surveying process, the positioning rod is first pushed by the push rod to compress the first spring. A spring simultaneously disengages the positioning rod from the rotating rod, causing the rotating rod to rotate upwards, which in turn drives the automatic sunshade to rotate upwards. After the automatic sunshade opens, it can provide auxiliary sun and rain protection for surveyors during engineering surveying. This minimizes the risk of heatstroke or illness from rain exposure for surveyors working in such environments for extended periods. This also relates to existing technology (Chinese patent application CN202020429317.8, filed March 29, 2020) for an auxiliary surveying device for engineering surveying. The new device has a simple structure and reasonable design. It can adjust the height and angle of the surveying device body. The sunshade structure can avoid observation errors caused by sunlight and can also protect the staff from rain on cloudy or rainy days, making it highly practical. Although existing technologies can provide support and protection, they are prone to damage to fragile parts when the surveying instrument is tilted, and it is difficult to control the safety during use. Furthermore, the waterproof mechanism can easily affect normal surveying work, is prone to obstruction, and affects the easy operation in non-rainy weather. In addition, it is difficult to adapt to other environments if it only serves as a waterproof mechanism.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing protective surveying devices used in surveying engineering. Summary of the Invention

[0009] Preferably, the protective component and the rotating ring form a rotating structure, and the rotating ring forms an elastic rotating structure with the protective component through the lug and the compression spring 1. The rotating ring forms a linkage compression structure with the clamp 1 through the lug and the compression rod. At the same time, the clamp 1 forms an elastic locking structure with the protective component through the compression spring 2. The protective component forms a limiting engagement structure with the surveying instrument body through the clamp 1.

[0010] Preferably, the symmetrical nesting mechanism further includes a locking block one that is elastically sliding and adjustable on the inner surface of the nesting component, and a cover plate is rotatably connected to the inner surface of the nesting component. A locking block two is elastically sliding and connected to the inner surface of the cover plate, and the locking block two is engaged with the inner surface of the nesting component. At the same time, a compression tank is nested and connected to the inner surface of the nesting component, and a connecting pipe is assembled on the lower surface of the compression tank through a valve body. A compression air bag is assembled at the other end of the connecting pipe.

[0011] Preferably, the nested component forms a limiting engagement structure with the surveyor body through a first locking block, and the nested component forms a limiting structure with the cover plate through a second locking block. The nested component also forms an embedded structure with the compression tank, while the compression tank forms a ventilation expansion protection structure with the compression airbag through a connecting pipe.

[0012] Preferably, the built-in nesting mechanism further includes an assembly that is connected through the outer surface of the handle, and a turntable is rotatably connected to the inner surface of the assembly. The turntable is rotatably connected to a connecting rod via an off-axis. At the same time, a second locking piece is rotatably connected to the other end of the outer surface of the connecting rod, and the second locking piece is limited and slidably placed on the inner surface of the assembly. The second locking piece is also limited and locked to the lower side of the inner surface of the handle. A guide post is installed on the outer surface of the second locking piece, and a return spring is elastically connected between the guide post and the assembly.

[0013] Preferably, the handle and the assembly form a nested structure, and the assembly forms a crank-connecting rod mechanism with the second locking piece through the turntable and connecting rod. The second locking piece forms an elastic sliding structure with the assembly through the guide post and the return spring.

[0014] Preferably, the inner surface of the waterproof and sun-protective component is rotatably connected to a bidirectional lead screw, and the outer surface of the bidirectional lead screw is threadedly connected to a slider. The outer surface of the slider is rotatably connected to a cross rod, and the outer surface of the cross rod is rotatably connected to a shrink plate.

At the same time, the outer surface of the waterproof and sun protection component has a corrugated structure.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This protective surveying device for surveying engineering, adaptable to multiple environments, is equipped with protective components that are easy to nest and assemble. Together with a compressed airbag and a compressed tank, it controls the protective stability of fragile lenses. Heat dissipation is achieved through heat sinks assembled on the side of the surveying instrument body, improving the heat dissipation effect. Through nested assembly accessories, the waterproof and sun-proof components with adjustable telescopic movement are controlled to perform waterproof and sun-proof work.

[0017] 2. This protective surveying device for surveying engineering, adaptable to multiple environments, is equipped with a locking and limiting mechanism. This mechanism allows for effective control of the clamping rod of the hanging lug assembly via the rotating ring of the protective component assembly. Adjusting the position of the locking component allows the protective component to be stably locked onto the surveying instrument body via the sliding of the locking component, improving the stability of the locking assembly. Furthermore, the use of a positioning pin prevents the compressed air bladder inside the protective component from being installed backwards, enhancing safety and stability during operation. Additionally, a symmetrical nesting mechanism facilitates the limiting and locking assembly of the nested components, controlling the stability of the compressed tank assembly. The connecting pipe of the compressed pipe assembly also controls the stability between the compressed pipe and the compressed air bladder.

[0018] 3. This protective surveying device for surveying engineering, adaptable to various environments, is equipped with a built-in nesting mechanism. This mechanism, via a crank-connecting rod, effectively and stably engages the components with the handle, improving the stability of the assembled waterproof and sun-protective components and enhancing the stability of the surveying instrument itself. This also prevents disruption to portability during normal operation. Furthermore, the small motor built into the waterproof and sun-protective components effectively controls the position of the bidirectional lead screw adjusting slider and the unfolding of the crossbar, adjusting the stability of the shrink plate. The sliding adjustment between the shrink plate and the end of the crossbar further enhances the operational stability of the waterproof and sun-protective components. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-10 The present invention provides a technical solution: a protective surveying device for surveying engineering that is adaptable to multiple environments, which is provided with a base 1 and a lifting component 2 assembled on the upper surface of the base 1.

[0023] Example 1: As Figures 1-10 The present invention provides the following technical solution: a protective surveying device for surveying engineering that is adaptable to multiple environments, comprising: a surveying instrument body 3, assembled on the upper surface end of a lifting component 2, with a lens 4 installed on the left side of the outer surface of the surveying instrument body 3, and heat sinks 5 attached to the front and rear sides of the outer surface of the surveying instrument body 3, a handle 6 installed on the upper surface of the surveying instrument body 3, and a protective component 8 connected to the inner surface of the surveying instrument body 3 through a locking and limiting mechanism, and a nesting component 17 connected to the surveying instrument body 3 through a symmetrical nesting mechanism, and an accessory 23 connected to the outer surface of the handle 6 through a built-in nesting mechanism, and a waterproof and sun-proof component 29 installed on the upper surface of the accessory 23.

[0024] In use, a heat sink 5 is assembled on the outer surface of the surveying instrument body 3. The thin metal heat dissipation material can effectively protect against falls while dissipating heat. The protective component 8 assembled on the surveying instrument body 3 is nested with the lens 4 to protect the lens 4. The compression airbag 10 and compression tank 21 assembled on the protective component 8 are used to improve the stability of the protective component 8 and improve the safety of the lens 4. The use of the accessory 23 assembled on the handle 6 and the waterproof and sun protection component 29 can improve the sun protection and waterproof performance of the surveying instrument body 3 by building an extension-type waterproof and sun protection part 34 in the waterproof and sun protection component 29. This improves the waterproof and sun protection effect, avoids the large protective volume affecting the surveying instrument body 3, and reduces the portability of the surveying instrument body 3 during normal operation.

[0025] Example 2: Figures 1-8 The technical solution shown, based on Embodiment 1, further discloses the protective effect on fragile parts, improves the stability of the protective assembly, and allows for rapid assembly and replacement of the protective parts after startup, thus improving the stability of the safety protection device. It solves the problem that fragile parts are easily damaged when the surveying instrument tilts, and that safety during use is difficult to control. Specifically, the locking and limiting mechanism includes a positioning pin 7 nested on the inner surface of the surveying instrument body 3, and a protective component 8 is installed on the outer surface of the positioning pin 7. A nested ring 9 is nested on the inner surface of the protective component 8, and a compression airbag 10 is installed on the outer surface of the nested ring 9. The surveying instrument body 3 forms a limiting nested structure with the protective component 8 via the positioning pin 7, and the protective component 8 forms an embedded structure with the compression airbag 10 via the nested ring 9. Figure 4 , Figure 5 and Figure 6 As shown, a rotating ring 11 is rotatably connected to the inner surface of the protective component 8, and a hanging lug 12 is installed at equal angles on the outer surface of the rotating ring 11. A compression spring 13 is elastically connected between the hanging lug 12 and the protective component 8. A compression rod 14 is rotatably connected to the outer surface of the hanging lug 12, and a locking piece 15 is rotatably connected to the inner surface of the compression rod 14, limiting and sliding the locking piece 15 on the inner surface of the protective component 8. A compression spring 16 is elastically connected between the locking piece 15 and the protective component 8, thus locking the locking piece 15 onto the inner surface of the surveying instrument body 3. Figure 4 , Figure 5 and Figure 6 As shown, the protective component 8 and the rotating ring 11 form a rotating structure, and the rotating ring 11 forms an elastic rotating structure with the protective component 8 through the hook 12 and the compression spring 13. Furthermore, the rotating ring 11 forms a linkage compression structure with the clamp 15 through the hook 12 and the compression rod 14. Simultaneously, the clamp 15 forms an elastic locking structure with the protective component 8 through the compression spring 16, and the protective component 8 forms a limiting engagement structure with the surveying instrument body 3 through the clamp 15. Figure 7and Figure 8 As shown, the symmetrical nested mechanism also includes a locking block 18 that is elastically adjustable on the inner surface of the nested component 17, and a cover plate 19 is rotatably connected to the inner surface of the nested component 17. A locking block 20 is elastically slidably connected to the inner surface of the cover plate 19, engaging the locking block 20 onto the inner surface of the nested component 17. Simultaneously, a compression tank 21 is nested and connected to the inner surface of the nested component 17, and a connecting pipe 22 is assembled to the lower surface of the compression tank 21 via a valve body. A compression airbag 10 is assembled to the other end of the connecting pipe 22. Figure 7 and Figure 8 As shown, the nested component 17 forms a limiting engagement structure with the surveyor body 3 through the first card block 18, and the nested component 17 forms a limiting structure with the cover plate 19 through the second card block 20. The nested component 17 also forms an embedded structure with the compression tank 21. Meanwhile, the compression tank 21 forms a ventilation expansion protection structure with the compression airbag 10 through the connecting pipe 22.

[0026] In use, a protective component 8 is nested and assembled on the side of the lens 4 assembled on the main body 3 of the surveying instrument. During the assembly process, the positioning pin 7 of the protective component 8 is used for positioning to prevent reverse assembly. During assembly, the rotating ring 11 inside the protective component 8 is manually controlled to rotate, thereby driving the hanging ear 12 to rotate simultaneously. The clamping spring 13 between the hanging ear 12 and the protective component 8 is compressed and contracted. The rotation of the hanging ear 12 drives the clamping rod 14 to drive the locking piece 15 to slide internally, thereby controlling the contraction of the locking piece 15. The locking piece 15 compresses and contracts the clamping spring 16, thus cooperating with the positioning pin 7 installed on the protective component 8 and the locking piece 15 assembled on the protective component 8 to assemble on the inner surface of the main body 3 of the surveying instrument. Loosening the rotating ring 11 allows the elasticity of the clamping spring 13 and the clamping spring 16 to extend and contract. The expansion allows for control of the stability of the protective assembly 8. The compressed airbag 10, assembled with the nesting ring 9, is stably nested within the protective assembly 8, improving the stability of the compressed airbag 10 assembly. This facilitates assembly between the compressed airbag 10 and the connecting pipe 22. A nested assembly 17 is then installed within the surveyor body 3, controlling the locking block 18 and improving the stability of the nested assembly 17. The connecting pipe 22 is then installed on the underside of the nested assembly 17, allowing the cover plate 19, which is rotatably connected to the nested assembly 17, to be opened. This effectively assembles the compression tank 21 and connects it to the connecting pipe 22, improving the stability of the compression inflation assembly connection. This is used for inflation protection in case the surveyor body 3 is dropped. Furthermore, the cover plate 19, rotatably connected to the nested assembly 17, along with the locking block 20 inside the cover plate 19, effectively improves the stability of the compression tank 21 assembly, preventing it from falling off.

[0027] Example 3: Figure 9 and Figure 10The technical solution shown, based on Embodiment 2, also discloses a lightweight design that adapts to different environments, improves ease of use, and avoids affecting normal work. It solves the problems of waterproof mechanisms easily interfering with normal surveying work, causing obstruction, and hindering work in non-rainy weather. Furthermore, it addresses the issue of waterproof mechanisms being unsuitable for use in other environments. Specifically, the built-in nested mechanism includes a component 23 that penetrates the outer surface of the handle 6. A turntable 24 is rotatably connected to the inner surface of the component 23, and a connecting rod 25 is rotatably connected to the turntable 24 via an off-axis. A second locking piece 26 is rotatably connected to the other end of the outer surface of the connecting rod 25, limiting and sliding the second locking piece 26 on the inner surface of the component 23. The second locking piece 26 is also locked onto the lower side of the inner surface of the handle 6. A guide post 27 is installed on the outer surface of the second locking piece 26, and a return spring 28 is elastically connected between the guide post 27 and the component 23. Figure 9 and Figure 10 As shown, the handle 6 and the assembly 23 form a nested structure, and the assembly 23, through the turntable 24 and the connecting rod 25, forms a crank-connecting rod mechanism with the second locking piece 26. The second locking piece 26, through the guide post 27 and the return spring 28, forms an elastic sliding structure with the assembly 23. Simultaneously, the assembly 23, through the second locking piece 26, forms a limiting engagement structure with the handle 6. Figure 9 and Figure 10 As shown, a bidirectional lead screw 30 is rotatably connected to the inner surface of the waterproof and sun-protective component 29, and a slider 31 is threadedly connected to the outer surface of the bidirectional lead screw 30. A cross rod 32 is rotatably connected to the outer surface of the slider 31, and a shrink plate 33 is rotatably connected to the outer surface of the cross rod 32. The waterproof and sun-protective component 29 is installed between the shrink plate 33 and the waterproof and sun-protective component 34. Figure 9 and Figure 10 As shown, the waterproof and sun protection component 29 forms a threaded sliding structure with the slider 31 via the bidirectional lead screw 30, and the slider 31 forms a compression and extension structure with the shrink plate 33 via the cross rod 32. The shrink plate 33, the waterproof and sun protection component 34, and the waterproof and sun protection component 29 form an integrated structure. Meanwhile, the outer surface of the waterproof and sun protection component 34 has a corrugated structure.

[0028] In rainy or sunny conditions, the waterproof and sun-protective components 29 are assembled into accessory 23, which is stably nested into the handle 6. This controls the rotation of the turntable 24 assembled into accessory 23. The off-axis of the turntable 24 drives the connecting rod 25 to adjust the second locking piece 26 within accessory 23, thus controlling the stability of the second locking piece 26's movement. This slightly lifts accessory 23 and nests the second locking piece 26 assembled into accessory 23 into the inner surface of the handle 6. When in operation, the second locking piece 26 will be secured by its outer assembly. The guide post 27 is connected to the reset spring 28, which controls the stability of the second locking piece 26 during use and improves the stability of the assembly between the mounting part 23 and the handle 6, preventing it from falling off. This allows the motor built into the waterproof and sun-protective component 29 to be activated, controlling the bidirectional lead screw 30 to drive the slider 31 for centering adjustment, and driving the other end of the assembled cross rod 32 to slide and rotate the shrink plate 33 to unfold. This allows the waterproof and sun-protective component 34 between the shrink plate 33 and the waterproof and sun-protective component 29 to unfold, thereby protecting the surveying instrument body 3.
