Description
Technical Field
[0001] This utility model relates to an instrument and device for field surveying, and in particular to a protective device for field surveying instruments, belonging to the technical field of surveying instruments. Background Technology
[0002] Field surveying, as a crucial step in acquiring geospatial data, plays an indispensable role in numerous fields such as infrastructure construction, resource exploration, urban planning, and the updating and improvement of Geographic Information Systems (GIS). However, the complexity and uncertainty of the field surveying environment present many severe challenges to surveying instruments, significantly impacting their accuracy, reliability, and lifespan. In the field, rugged terrain is a common obstacle. Whether it's mountains, jungles, deserts, swamps, or other complex landforms, surveyors must carry their instruments through these environments.
[0003] In mountainous areas, the rugged roads cause severe bumps and vibrations when vehicles travel on them; hiking through jungles, with its undulating terrain, also subjectes instruments to constant vibration. These continuous and irregular vibrations can cause displacement, loosening, or even damage to the precision components inside the instruments. For example, instruments such as levels and total stations require extremely high positional accuracy for their internal optical and electronic components; even minute displacements can lead to significant deviations in measurement results, thus affecting the accuracy of the entire surveying project.
[0004] Therefore, there is an urgent need to improve a protective device for field surveying instruments in order to solve the aforementioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a protective device for field surveying instruments. The outer shell provides a physical protective barrier for the internal components, while the buffer components absorb and disperse impact forces, reducing their influence on the internal protective chamber. The honeycomb aluminum plate provides further structural support and cushioning protection, and the memory foam layer fits tightly to the instrument, adapting to its shape and providing comprehensive, enveloping protection. It has excellent cushioning performance, further absorbing and buffering minor vibrations and impacts transmitted from the honeycomb aluminum plate, ensuring the instrument remains stable within the internal protective chamber. Through the coordinated use of multiple protective methods, field surveying instruments can be comprehensively and effectively protected during transportation in harsh environments and when relocating work sites.

Detailed Implementation
[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0024] like Figure 1 - Figure 4As shown in the figure, this embodiment provides a protective device for field surveying instruments, including an outer shell 1, a buffer assembly 2, and an inner protective chamber assembly 3. The inner protective chamber assembly 3 is located inside the outer shell 1. The outer shell 1, as the outermost structure of the entire protective device, provides the primary physical protective barrier for the inner components. The buffer assembly 2 is located between the outer shell 1 and the inner protective chamber assembly 3. The buffer assembly 2 plays a crucial role in shock absorption and cushioning. When the outer shell 1 is impacted, the buffer assembly 2 absorbs and disperses the impact force, reducing the impact on the inner protective chamber assembly 3. The inner protective chamber assembly 3 includes a honeycomb aluminum plate 4 and a memory foam layer 5. The honeycomb aluminum plate 4 is located outside the inner protective chamber assembly 3, and the inner wall of the honeycomb aluminum plate 4 is fixedly connected to the memory foam layer 5. The instrument is located inside the memory foam layer 5. Plate 4, as the outer structure of the internal protective chamber component 3, provides further structural support and cushioning protection for the instrument. Its unique sandwich structure has a high strength-to-weight ratio, which can effectively disperse and withstand the impact force transmitted from the cushioning component 2 while reducing the overall weight, preventing the impact force from acting directly on the instrument. In addition, the honeycomb aluminum plate 4 also has a certain heat insulation performance, which can reduce the impact of external temperature changes on the instrument. The memory foam layer 5 fits tightly to the instrument and can adapt to the shape of the instrument to provide all-round wrap-around protection. It has good cushioning performance, which can further absorb and buffer the small vibrations and impact forces transmitted from the honeycomb aluminum plate 4, ensuring that the instrument remains stable within the internal protective chamber component 3, avoiding hard collisions between the instrument and other components, and playing a fine protective role for the instrument.
[0025] Among them, such as Figure 1 - Figure 4 As shown, the honeycomb aluminum panel 4 includes a face panel 21, a honeycomb core 22, and a back panel 23. The back panel 23 abuts against the memory foam layer 5, and the face panel 21 corresponds to the outer shell 1. As the part of the honeycomb aluminum panel 4 that is in direct contact with the outside, the face panel 21 bears the various forces from the outside. The honeycomb core 22 is located between the face panel 21 and the back panel 23 and is fixedly connected to the face panel 21 and the back panel 23. The honeycomb core 22 has a regular honeycomb structure and is the core supporting component of the honeycomb aluminum panel 4. It provides high strength and rigidity with a small mass, so that the honeycomb aluminum panel 4 can maintain good flatness and shape stability when subjected to external forces, and prevent the face panel 21 and the back panel 23 from being excessively deformed due to force. The back panel 23 and the face panel 21 together hold the honeycomb core 22 to form a stable sandwich structure, which enhances the overall structural strength of the honeycomb aluminum panel 4.
[0026] Among them, such as Figure 1 - Figure 4As shown, the buffer assembly 2 includes multiple hydraulic telescopic rods 31 and multiple universal joint rods 32. An abutment box 33 is located near the panel 21 on the outer housing 1. The multiple universal joint rods 32 are fixedly connected to the abutment box 33 and the opposite side of the outer housing 1, respectively. One end of each pair of opposite universal joint rods 32 corresponds to one end of the hydraulic telescopic rod 31. The hydraulic telescopic rod 31 is a key shock-absorbing component of the buffer assembly 2. It is filled with liquid. When subjected to external force, the liquid flows within the hydraulic telescopic rod 31, generating resistance and converting mechanical energy into heat energy, thereby consuming impact energy and effectively reducing vibration amplitude. When the instrument protection device is impacted, it can quickly suppress the vibration caused by external impact. To prevent the instrument from being damaged by excessive vibration due to violent shaking, one side of the universal joint rod 32 is fixed to the contact box 33 and the outer housing 1, while the other end of the universal joint rod 32 is allowed to rotate in multiple directions, so that the buffer assembly 2 can adapt to impact forces from different directions. The contact box 33 is located near the panel 21 of the outer housing 1, serving as a concentrated force point for the connection between the buffer assembly 2 and the outer housing 1. When the outer housing 1 is impacted, the contact box 33 can concentrate the impact force and distribute it evenly to the entire buffer assembly 2 through the multiple universal joint rods 32 connected to it, avoiding excessive local concentration of impact force that could damage a part of the buffer assembly 2.
[0027] Furthermore, such as Figure 1 - Figure 4 As shown, both ends of the hydraulic telescopic rod 31 are fixedly connected to U-shaped plates 41, and a rotating rod 42 is fixedly connected between the two sides of the U-shaped plates 41. The rotating rod 42 passes through the universal joint connecting rod 32 and is rotatably connected to the universal joint connecting rod 32. The U-shaped plates 41 are fixed at both ends of the hydraulic telescopic rod 31 and play a key role in connecting the hydraulic telescopic rod 31 and the universal joint connecting rod 32. It provides an installation position for the rotating rod 42, ensuring that the rotating rod 42 is stably connected to the hydraulic telescopic rod 31, thereby enabling the hydraulic telescopic rod 31 to establish a rotatable connection with the universal joint connecting rod 32 through the rotating rod 42, combining its own buffering function with the multi-angle rotation characteristics of the universal joint connecting rod 32.
[0028] Furthermore, such as Figure 1 - Figure 4 As shown, the U-shaped plates 41 at both ends of the universal joint link 32 are perpendicular, allowing the universal joint link 32 to rotate in both the longitudinal and lateral directions. The U-shaped plates 41 arranged perpendicularly at both ends provide a support structure for the universal joint link 32 to rotate in both the longitudinal and lateral directions, enabling the universal joint link 32 to rotate freely in two mutually perpendicular planes, thereby achieving a multi-directional buffering function.
[0029] Furthermore, such as Figure 1 - Figure 4As shown, a return spring 61 is sleeved on the outer wall of the universal joint connecting rod 32. The two ends of the return spring 61 are connected to the U-shaped plates 41 at both ends of the universal joint connecting rod 32. The return spring 61 works in conjunction with the hydraulic telescopic rod 31 to further optimize the buffering effect and help the hydraulic telescopic rod 31 return to its original position.
[0030] Among them, such as Figure 1 - Figure 4 As shown, the opening and closing side of the outer housing 1 is provided with a buckle 71. The main function of the buckle 71 is to firmly fix the opening and closing sides of the outer housing 1 together, ensuring that the entire protective device forms a relatively closed space.
[0031] like Figure 1 - Figure 4 As shown, the principle of the field surveying instrument protection device provided in this embodiment is as follows: During field surveying, when the outer shell 1 is subjected to impact forces from various directions, the impact first acts on the outer shell 1. Multiple universal joints 32 and hydraulic telescopic rods 31 adjust their angles according to the impact direction to adapt to impact forces from different directions. The hydraulic telescopic rods 31 convert the impact energy into heat energy, consume the impact energy, and effectively reduce the vibration amplitude. When the hydraulic telescopic rods 31 are working, they cooperate with the return spring 61 to further optimize the buffering effect. After the impact ends, the return spring 61 releases elastic potential energy to help the hydraulic telescopic rods 31 return to their original position. The impact force after initial buffering by the buffer component 2 is transmitted to the honeycomb aluminum plate 4 of the inner protective chamber component 3. The panel 21 of the honeycomb aluminum plate 4 first bears the force transmitted from the buffer component 2, and then the force is dispersed by the honeycomb core 22 with its regular honeycomb structure. Finally, the memory foam layer 5 further absorbs and buffers the small vibrations and impact forces transmitted from the honeycomb aluminum plate 4, ensuring that the instrument remains stable in the inner protective chamber component 3.
