Description

Technical Field

[0001] This application relates to the field of engineering surveying technology, specifically a benchmark for engineering surveying. Background Technology

[0002] In engineering surveying, the benchmark is an important tool for marking measuring points and assisting in readings. Its stability and the clarity of scale / marking observations directly affect the surveying efficiency and accuracy.

[0003] Chinese utility model patent CN222865939U discloses a surveying pole for engineering surveying. Its stability is improved by extending a limiting rod into the soil via a limiting component, effectively reducing the likelihood of the pole tilting or falling over. However, while the limiting component enhances stability, surveying operations are often conducted outdoors, making the pole susceptible to lighting conditions. In strong sunlight, direct sunlight on the pole's markings or scales can cause glare, making it difficult for surveyors to read clearly and increasing reading errors. Similarly, in low-light conditions such as cloudy days, evenings, nights, or tunnels, insufficient natural light leads to blurred readings and difficulty in identification, often requiring repeated observation and confirmation by surveyors. This not only reduces work efficiency but can also affect the quality of the final survey results due to inaccurate readings.

[0004] Therefore, this application provides a benchmark for engineering surveying to solve the above problems. Utility Model Content

[0005] This application provides a benchmark for engineering surveying, aiming to solve the problems mentioned in the background art. Although existing benchmarks for engineering surveying can improve standing stability through limiting components, their surface scales or markings are easily affected by strong light reflection and dim light during outdoor operations, resulting in unclear readings and increased errors, which not only reduces work efficiency but may also affect the quality of surveying results.

[0006] To achieve the above objectives, this application provides the following technical solution: a surveying pole, comprising a pole body and scales / markers disposed on the pole body, wherein the surveying pole further comprises an observation assistance structure disposed on the pole body for providing observation assistance for the scales / markers on the pole body;

[0007] The observation auxiliary structure includes a detachable assembly mounted on the pole, a sunshade component on one side of the detachable assembly to block sunlight and prevent glare from the scale / markings on the pole, and an illumination component fixed inside the sunshade component to provide illumination for the scale / markings on the pole in low-light conditions. By combining the sunshade component and the illumination component, the sunshade component can prevent glare from the scale / markings in strong light, while the illumination component provides illumination in low light. This adapts to varying lighting conditions, improving the clarity of the scale / markings on the pole and reducing the number of repeated observations. This improves surveying efficiency and ensures the accuracy of the surveying results. Furthermore, the detachable assembly can be flexibly fixed at different positions on the pole, ensuring that the sunshade component and the illumination component accurately correspond to the scale / marking areas to be observed, adapting to the scale / marking reading needs of different surveying scenarios.

[0008] Preferably, in order to achieve convenient assembly, disassembly, and flexible positioning of the observation auxiliary structure on the pole, and to meet the needs of scale / marking observation positions in different surveying scenarios, the assembly / disassembly assembly includes a sleeve block fitted on the pole, a connecting plate symmetrically fixed on the sleeve block, locking screws screwed onto the connecting plate for abutting against the pole, and a knob fixed on the end of the locking screw away from the pole. By rotating the knob, the locking screw can be driven to move along the screw hole of the connecting plate, and the sleeve block can be fixed to the pole by friction. Reverse rotation can loosen and slide the sleeve block to adjust its position, thereby making the installation and disassembly of the observation auxiliary structure quick and easy, adapting to different measurement heights and position requirements, and improving work efficiency and flexibility of use.

[0009] Preferably, in order to enhance the connection stability between the locking screw and the rod body, and to protect the surface of the rod body from scratches, a rubber pad for contacting the rod body is fixedly provided at the end of the locking screw away from the knob. The rubber pad has a high coefficient of friction, which increases the friction force when in contact with the rod body, making the connection more stable. At the same time, the soft texture of the rubber pad can buffer the pressure of the locking screw on the rod body, preventing the surface of the rod body from being scratched by the hard screw. This ensures the firmness of the observation auxiliary structure installed on the rod body, extends the service life of the rod body, and reduces the maintenance cost of the equipment.

[0010] Preferably, in order to achieve sunshade and improve the clarity of observation of the scale / marking in strong light environment, the sunshade is an arc-shaped cover or a fan-shaped cover; the arc-shaped cover or fan-shaped cover has a large light-blocking area and a suitable curvature, so that when sunlight shines on the arc-shaped cover or fan-shaped cover, it will be blocked by the cover and cannot directly shine on the scale / marking surface. Thus, in strong light environment, it can significantly reduce the reflectivity of the scale / marking surface, so that surveyors can clearly see the scale / marking, reduce reading errors, and improve the accuracy and efficiency of surveying.

[0011] Preferably, to provide illumination and make the scale / marking clearly visible, the illumination element is a light strip or LED beads, which are distributed along the inner wall of the sunshade. The light strip or LED beads can emit light, and when the light from the light strip or LED beads shines on the surface of the scale / marking, according to the principle of light reflection, the scale / marking will reflect the light into the eyes of the surveyor. Thus, in low-light environments such as cloudy days, evenings, nights, or tunnels, it can effectively solve the problem of difficulty in identifying scale / marking due to insufficient light, improve the accuracy and speed of surveyor readings, and thus improve the efficiency and quality of the entire surveying work.

[0012] Preferably, in order to improve the shading and lighting effects, the observation auxiliary structure further includes an angle adjustment component disposed on the sleeve block for adjusting the angle of the shading component or the lighting component; the design of the angle adjustment component can facilitate the real-time adjustment of the shading and lighting direction according to the angle of sunlight or the position of the observer, further improving the shading effect and lighting accuracy in different scenarios.

[0013] Preferably, to achieve flexible adjustment of the angle of the sunshade or lighting component, the angle adjustment assembly includes a connecting seat fixedly installed on one side of the sleeve block, a rotating shaft fixedly connected to the side of the sunshade near the sleeve block and rotatably connected to the connecting seat, a worm gear disposed in the connecting seat and fixedly sleeved at one end of the rotating shaft, a worm passing through the connecting seat and rotatably connected to the connecting seat, and a second knob disposed on the outside of the connecting seat and fixedly connected to one end of the worm. The worm meshes with one side of the worm wheel. By rotating the worm by the second knob, and then using the meshing transmission between the worm and the worm wheel, the rotating shaft and the connected sunshade and the lighting component on the sunshade can be driven to rotate around the connecting seat. Since the worm gear transmission has self-locking properties, when the second knob is stopped, the sunshade or lighting component can be stably maintained at the adjusted angle. Thus, surveyors can adjust the sunshade or lighting component to the optimal angle to adapt to different lighting conditions at different times and in different environments, improving the applicability and effectiveness of the equipment, and further ensuring the accuracy and efficiency of surveying work.

[0014] The surveying poles used in this project are designed with a combination of sunshades and lighting components. In strong light conditions, the sunshades prevent glare from the scales / markers, while the lighting components provide illumination in low light conditions. This ensures that the clarity of the scales / markers on the poles is maintained under different lighting conditions, reducing the number of repeated observations. This improves the efficiency of surveying operations and ensures the accuracy of the surveying results.

[0015] The surveying poles used in this project are designed with detachable components, which can be flexibly fixed at different positions on the pole body to ensure that the sunshade and lighting components can accurately correspond to the scale / marking area to be observed, and adapt to the scale / marking reading needs in different surveying scenarios.

[0016] The surveying and mapping poles used in this project are designed with angle adjustment components, which allow for real-time adjustment of the direction of the shading or lighting components according to the angle of sunlight or the observer's position. This improves the applicability and effectiveness of the equipment and further ensures the accuracy and efficiency of the surveying and mapping work. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Example 1

[0026] This embodiment provides a benchmark for engineering surveying, such as... Figures 1-4 As shown, the engineering surveying pole includes a pole body 1 and scales / markers set on the pole body 1. The engineering surveying pole also includes an observation auxiliary structure 2 set on the pole body 1 to provide observation assistance for the scales / markers on the pole body 1. The observation auxiliary structure 2 includes a disassembly and assembly assembly 21 set on the pole body 1, a sunshade 22 set on one side of the disassembly and assembly assembly 21 to block sunlight to prevent reflection of the scales / markers on the pole body 1, and an illumination component 23 fixedly set inside the sunshade 22 to provide illumination for the scales / markers on the pole body 1 in low light environment.

[0027] When in use, during engineering surveying work, the assembly and disassembly components 21 of the observation auxiliary structure 2 are first mounted on the pole 1. By fixing the assembly and disassembly components 21, the observation auxiliary structure 2 can be installed in a suitable position on the pole 1. In a strong light environment, the sunshade 22 can block sunlight from directly shining on the scale / marking on the pole 1, reducing the reflection on the scale / marking surface, so that the surveyors can observe clearly. In a low light environment, the lighting component 23 is turned on. Then, the light from the lighting component 23 can shine on the scale / marking. According to the principle of light reflection, the scale / marking reflects the light into the eyes of the surveyors, so as to ensure that the surveyors can accurately read the scale / marking.

[0028] Specifically, the disassembly and assembly assembly 21 includes a sleeve block 211 sleeved on the rod body 1, a connecting plate 212 symmetrically fixed on the sleeve block 211, a locking screw 213 screwed onto the connecting plate 212 for abutting against the rod body 1, and a knob 214 fixedly disposed on the end of the locking screw 213 away from the rod body 1.

[0029] When using the assembly / disassembly assembly 21 to install the observation auxiliary structure 2 onto the rod body 1, first, fit the sleeve block 211 onto the rod body 1 to a suitable height. At this time, since the connecting plate 212 is symmetrically fixed on the sleeve block 211, forming an integral structure with the sleeve block 211, then rotate the knob 214. Since the knob 214 is fixed at the end of the locking screw 213 away from the rod body 1, rotating the knob 214 will drive the locking screw 213 to rotate. The locking screw 213 is screwed onto the connecting plate 212. According to the principle of thread transmission, the locking screw 213 will rotate along... Move the screw through the threaded hole on the connecting plate 212 toward the rod body 1. Then, continuously rotate the knob 214 until the locking screw 213 is tightly pressed against the rod body 1. Using the friction between the locking screw 213 and the rod body 1, the sleeve 211 and the entire observation auxiliary structure 2 can be fixed to the rod body 1. Conversely, when it is necessary to disassemble or adjust the position, rotate the knob 214 in the opposite direction to move the locking screw 213 away from the rod body 1, reducing the friction between it and the rod body 1. At this time, the sleeve 211 can slide on the rod body 1, so that the position of the observation auxiliary structure 2 can be easily adjusted or it can be disassembled.

[0030] Furthermore, a rubber pad 215 for contacting the rod body 1 is fixedly provided at the end of the locking screw 213 away from the knob 214;

[0031] As the rotating knob 214 moves the locking screw 213 toward the rod 1, a rubber pad 215 is fixedly installed at the end of the locking screw 213 away from the knob 214. As the locking screw 213 approaches the rod 1, the rubber pad 215 will first contact the surface of the rod 1. Because the rubber pad 215 has good flexibility and elasticity, it will deform to a certain extent after contacting the rod 1. This deformation can increase the contact area between the rubber pad 215 and the rod 1. At the same time, because the rubber has a high coefficient of friction, it can generate friction to prevent the sleeve 211 from sliding relative to the rod 1. The rubber pad 215 can also play a buffering role to prevent the locking screw 213 from making direct hard contact with the rod 1 and to prevent scratching the surface of the rod 1, so as to ensure the integrity and aesthetics of the rod 1. Then, the observation auxiliary structure 2 can be fixed on the rod 1.

[0032] In order to achieve sunshade and improve the clarity of observation of the scale / marking in strong light environment, the sunshade 22 is an arc-shaped or fan-shaped cover. The arc-shaped or fan-shaped cover has a large light-blocking area and a suitable curvature, so that when sunlight shines on the arc-shaped or fan-shaped cover, it will be blocked by the cover and cannot directly shine on the scale / marking surface. Thus, in strong light environment, it can significantly reduce the reflectivity of the scale / marking surface, so that surveyors can clearly see the scale / marking, reduce reading errors, and improve the accuracy and efficiency of surveying.

[0033] In addition, to provide illumination and make the scale / marks clearly visible, the illumination element 23 is a light strip or LED, which is distributed along the inner wall of the sunshade 22. The light strip or LED can emit light, and when the light from the light strip or LED shines on the surface of the scale / mark, according to the principle of light reflection, the scale / mark will reflect the light into the eyes of the surveyor. Thus, in low-light environments such as cloudy days, evenings, nights, or tunnels, it can effectively solve the problem of difficulty in identifying scales / marks due to insufficient light, improve the accuracy and speed of surveyor readings, and thus improve the efficiency and quality of the entire surveying work.

[0034] It should be noted that the sleeve 211 is fixedly equipped with a button for turning the lighting element 23 on and off, and a rechargeable battery for powering the lighting element 23. The button is electrically connected to the rechargeable battery and the lighting element 23 through a wire to form a closed circuit. When the button is pressed, the circuit is opened, and the current of the rechargeable battery is transmitted to the lighting element 23 through the wire to make it light up. Pressing the button again will open the circuit and turn off the lighting element 23. Furthermore, when the rechargeable battery is connected to an external charging power source, it can convert electrical energy into chemical energy for storage. When powering loads such as the lighting element 23, the stored chemical energy is converted into electrical energy for output through a forward chemical reaction.

[0035] Example 2

[0036] Unlike Example 1, as Figure 2 . Figure 3 and Figure 4 As shown, in order to improve the shading and lighting effects, the observation auxiliary structure 2 also includes an angle adjustment component 24 set on the sleeve block 211 for adjusting the angle of the shading component 22 or the lighting component 23. The angle adjustment component 24 includes a connecting seat 241 fixedly installed on one side of the sleeve block 211, a rotating shaft 242 fixedly connected to the side of the shading component 22 near the sleeve block 211 and rotatably connected to the connecting seat 241, a worm gear 243 set in the connecting seat 241 and fixedly sleeved to one end of the rotating shaft 242, a worm 244 passing through the connecting seat 241 and rotatably connected to the connecting seat 241, and a knob 245 set on the outside of the connecting seat 241 and fixedly connected to one end of the worm 244. The worm 244 meshes with one side of the worm gear 243.

[0037] When the angle of the shading element 22 or the lighting element 23 in the observation auxiliary structure 2 needs to be adjusted, the knob 245 is turned. Since the knob 245 is fixedly connected to one end of the worm 244, turning the knob 245 will synchronously drive the worm 244 to rotate within the connecting seat 241. Since the worm 244 meshes with one side of the worm wheel 243, according to the transmission principle of the worm wheel 244 and worm 243, the rotation of the worm 244 will drive the worm wheel 243 to rotate. The rotation of the worm wheel 243 will then drive the rotating shaft 242 to rotate within the fixedly mounted sleeve 211. The rotating shaft 242 is fixedly connected to the side of the sunshade 22 near the sleeve block 211. Therefore, the rotation of the shaft 242 will drive the sunshade 22 to rotate. By rotating the knob 245 by different numbers of turns or angles, the angle of the sunshade 22 or the lighting element 23 can be adjusted to meet the observation needs under different lighting conditions. Furthermore, since the worm gear 244 and worm 243 transmission has self-locking properties, when the knob 245 is stopped, the sunshade 22 or the lighting element 23 can be stably maintained at the adjusted angle.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
