Description

Technical Field

[0001] This utility model belongs to the field of third and fourth order leveling, specifically relating to a third and fourth order leveling rod for nighttime illumination measurement. Background Technology

[0002] In the field of surveying and mapping engineering, fourth-order leveling is widely used in urban municipal construction, road construction, and small building surveying, requiring the use of a leveling rod and a level instrument to complete elevation data acquisition. Existing 2-meter third and fourth-order leveling rods are mostly made of aluminum alloy or fiberglass, with only standard graduations printed on the rod body and no dedicated nighttime auxiliary structure. This presents significant limitations when working at night or in low-light environments (such as tunnel construction or nighttime emergency surveying): First, relying on external flashlights, headlamps, and other lighting tools can easily cause glare from direct light hitting the level instrument lens, or create shadows on the graduations due to improper illumination angles, leading to increased reading errors and making it difficult to meet the accuracy requirement of ±5 mm / km for fourth-order leveling; Second, visually aligning the center of the leveling rod with the line of sight of the level instrument at night is difficult, requiring repeated adjustments to the rod position, significantly reducing work efficiency; Third, some temporary lighting solutions lack protective designs and are prone to failure in the event of dew or light rain at night, exhibiting poor adaptability. Although there are a few measuring tools with simple lighting, most of them are independent external types. After installation, they are prone to shaking, which affects the straightness of the scale. They also lack anti-glare and quick alignment functions, and cannot fundamentally solve the problems of accuracy and efficiency in third and fourth order leveling at night. Utility Model Content

[0003] In order to optimize and upgrade the existing technology, this utility model provides a third- or fourth-order leveling rod for nighttime illumination measurement.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a third or fourth order leveling rod for nighttime illumination measurement, characterized in that it includes a black-faced rod body (1) and a red-faced rod body (2), and infrared alignment components are symmetrically provided on the front surfaces of the black-faced rod body (1) and the red-faced rod body (2); Integrated lighting modules are symmetrically provided on both sides of the black-faced ruler body (1) and the red-faced ruler body (2); The black-faced ruler body (1) is marked with uniform black scale lines, and the red-faced ruler body (2) is marked with uniform red scale lines. The integrated lighting module includes an embedded wire groove (3), which includes a lampshade support layer (8) and a triangular baffle (9). The triangular baffle (9) fixes the lampshade and is located on one side of the opening of the embedded wire groove (3). The embedded wire groove (3) is fixed to both sides of the black-faced ruler body (1) and the red-faced ruler body (2). An infrared receiver is installed next to the objective lens of the leveling instrument at the observation end to receive infrared signals from the leveling rod end.

[0005] Furthermore, the integrated lighting module also includes a lighting device, which includes a flexible rechargeable LED light strip (4) and an anti-glare diffuse reflection lampshade (7); the flexible rechargeable LED light strip (4) is fixed on the lampshade support layer (8), and a control switch (6) is connected to the upper end of the LED light strip (4). The control switch (6) is connected to a USB charging cable (5), which is specifically used to charge the flexible LED light strip (4); the anti-glare diffuse reflection lampshade (7) is embedded in the lampshade support layer (8).

[0006] Furthermore, the embedded wire groove (3), the lampshade support layer (8), and the triangular baffle (9) are all made of aluminum alloy.

[0007] Furthermore, the infrared alignment component includes an infrared emitter (10), which has a built-in rechargeable lithium battery and is designed to be IP65 waterproof.

[0008] Furthermore, the infrared emitter (10) is fixed at both ends of the leveling rod.

[0009] Furthermore, the infrared transmitter (10) is fixed to both ends of the leveling rod by the infrared transmitter clip (11).

[0010] Furthermore, the infrared emitter (10) is installed at the middle position of the lower end of the black-faced ruler body (1) and the red-faced ruler body (2).

[0011] When the line of sight of the level instrument is aligned with the center line of the leveling rod, the receiving device can accurately capture the infrared light emitted by the infrared transmitter and indicate "alignment complete" through a buzzer. The beneficial effects of this utility model are: 1. This utility model effectively overcomes the shortcomings of existing nighttime measuring tools. Existing tools with simple lighting are mostly independent external devices, which are prone to shaking after installation, affecting the straightness of the ruler, and lack anti-glare and quick alignment functions. This utility model integrates lighting through embedded LED light strips and diffused light covers, eliminating the risk of shaking and achieving glare-free and uniform illumination.

[0012] 2. The main body of the ruler, both black and red, is made of wood and is marked with uniform graduations. The black side of the ruler has black graduations spaced 1 cm apart, ranging from 00 to 20; the red side of the ruler has red graduations spaced 1 cm apart, ranging from 48 to 68. Reading from both sides facilitates the checking of numerical errors.

[0013] 3. The integrated lighting module includes an embedded cable tray made of aluminum alloy, with an aluminum alloy lampshade support layer in the middle of the embedded cable tray. Triangular baffles made of aluminum alloy are designed on both inner sides. The function of the triangular baffles is to fix the lampshade and prevent it from sliding out of the embedded cable tray. A low-power flexible rechargeable LED light strip is fixed on the lampshade support layer. A control switch is connected to the upper end of the LED light strip, and the control switch is connected to a USB charging cable. An open rectangular anti-glare diffuse reflection lampshade is embedded in the lampshade support layer.

[0014] 4. The infrared alignment assembly includes a cylindrical infrared emitter with a built-in rechargeable lithium battery. The infrared emitter is secured to the body of the emitter and extends towards the edge of the leveling rod, finally locking both ends of the leveling rod. Additionally, an infrared receiver is installed next to the objective lens of the leveling instrument at the observation end, specifically for receiving infrared signals from the leveling rod end.

[0015] 5. Equipped with an infrared alignment component, the infrared transmitter links with the level instrument receiver to achieve rapid and accurate alignment. This design significantly improves the stability of the leveling rod, the accuracy of readings, and the alignment efficiency of third and fourth-order leveling at night, effectively ensuring the precision and reliability of nighttime measurements.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, this utility model provides a third- or fourth-order leveling rod for nighttime illumination measurement, including a black-faced rod body 1, a red-faced rod body 2, an integrated lighting module, and an infrared alignment component.

[0020] The black-faced ruler body 1 is marked with uniform black graduation lines (00 to 20). The first 5 cm is shaped like an "E", and the next 5 cm consists of two equal-length black squares, arranged in an alternating black and white square pattern. The red-faced ruler body 2 is marked with uniform red graduation lines (48 to 68). The first 5 cm is shaped like an "E", and the next 5 cm consists of two equal-length red squares, arranged in an alternating red and white square pattern. The black and red-faced ruler bodies are primarily used for reading from both sides and for measurement verification. They effectively detect and correct gross errors caused by ruler movement, misreading, or other factors, ensuring accurate and precise readings. Regardless of whether the black or red face is used for measurement, both sides of the ruler provide uniform illumination, and the infrared transmitter ensures alignment with the level instrument from both sides. This symmetrical design avoids the hassle of repeatedly searching for or adjusting the ruler's orientation in dimly lit environments at night, achieving "usability from any side" and significantly improving the efficiency of continuous nighttime measurements.

[0021] The integrated lighting module includes an embedded wire groove 3 made of aluminum alloy. An aluminum alloy lampshade support layer 8 is designed in the middle of the embedded wire groove 3. Triangular baffles 9 made of aluminum alloy are designed on both sides inside the embedded wire groove 3. The triangular baffles 9 are fixed to the opening side of the embedded wire groove 3. The function of the triangular baffles 9 is to fix the lampshade and prevent the lampshade from sliding out of the embedded wire groove. A low-power, flexible, rechargeable LED strip 4 is fixed to the lampshade support layer 8. The LED strip 4 can provide illumination for approximately 6 hours. A control switch 6 is connected to the upper end of the LED strip 4, and the control switch 6 is connected to a USB charging cable 5, which is specifically used to charge the LED strip 4. An open rectangular anti-glare diffuse reflection lampshade 7 is embedded in the lampshade support layer 8. The open rectangular anti-glare diffuse reflection lampshade 7 is made of frosted PC (polycarbonate) material, which is highly impact-resistant, not easily broken by impact, and has a wide temperature resistance range (-40℃ to 120℃), capable of handling low-temperature nighttime environments. It has moderate light transmittance (60%-80%) and uniform diffuse reflection, preventing glare caused by excessive brightness in certain areas. The contact portion between the open rectangular anti-glare diffuse reflection lampshade 7 and the aluminum alloy lampshade support layer 8 is designed with a right-angle corner, ensuring a secure fixation of the lampshade to the lampshade support layer 8.

[0022] The infrared alignment assembly includes a cylindrical infrared emitter 10 and an infrared sensor 12. The infrared emitter 10 has a built-in rechargeable lithium battery with a replaceable battery life of ≥8 hours. It features an IP65 waterproof design, suitable for nighttime dew or light rain. An infrared emitter clip 11 secures the infrared emitter 10 to the body and extends towards the edge of the leveling rod until it is locked at both ends. The two cylindrical infrared emitters 10 are positioned at the lower center of the black-faced rod body 1 and the red-faced rod body 2. An infrared receiver is installed next to the objective lens of the leveling instrument at the observation end, specifically for receiving infrared signals from the leveling rod end. When the line of sight of the leveling instrument (the center line aimed by the lens) is aligned with the center line of the leveling rod, the receiver accurately captures the infrared light emitted by the infrared emitter and alerts the user with a buzzer indicating "alignment complete."

[0023] Finally, it should be noted that the above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. For those skilled in the art, various variations can be made based on the above description. Any modifications, substitutions, or improvements made within the spirit and principles of this utility model are within the protection scope of this utility model.
