Description

Technical Field

[0001] This utility model belongs to the field of construction surveying technology, and in particular relates to a surveying beacon. Background Technology

[0002] In the field of modern engineering construction, the requirements for measurement accuracy for long-distance linear projects, including underwater, underground, and above-ground projects, are constantly increasing, especially the standards for controlling axis deviation are becoming increasingly stringent. Compared with above-ground and underwater projects, underground linear projects are subject to multiple constraints such as confined spaces, complex geological conditions, and special operating environments, making it difficult to accurately control the axis deviation during the measurement process, which poses a severe challenge to ensuring project quality.

[0003] Therefore, designing a measuring beacon that can easily measure axis deviation is of great significance for long-distance alignment engineering. Utility Model Content

[0004] To address the shortcomings of related technologies, this utility model provides a measuring beacon. By placing the measuring beacon and a total station at two different traverse control points of the project, the total station measures the axial deviation of the project through the measuring beacon, ensuring that the axial deviation is within the allowable range and thus guaranteeing the construction quality of the project.

[0005] This utility model provides a measuring beacon, and a total station uses the measuring beacon to measure the axial deviation of an engineering project; the measuring beacon and the total station are located at two different traverse control points of the project; the measuring beacon includes:

[0006] A metal casing, wherein the metal casing has an opening provided along its length;

[0007] A glass shell is located at the opening of the metal shell; the glass shell and the metal shell together define a receiving cavity;

[0008] The LED bead is located inside the housing cavity and is mounted on a metal casing, with the light-emitting side of the LED bead facing the glass casing.

[0009] In this technical solution, the metal and glass housings together form a cavity, providing a stable and protective installation environment for the LED chips, enabling them to operate stably even in harsh environments (such as underground or underwater). The robust and durable metal housing can withstand external impacts, friction, and some harsh environmental factors, ensuring the LED chips function normally in complex engineering environments and extending the overall lifespan of the measuring beacon. The LED chips emit light towards the glass housing, allowing the total station to be clearly aimed, thereby improving the accuracy and reliability of measuring engineering axis deviations.

[0010] In some embodiments, the glass housing is arc-shaped, and the center of the arc of the glass housing is located within the receiving cavity.

[0011] In the technical solution, the glass shell is designed as an arc-shaped structure protruding outwards from the housing cavity. This allows the glass shell to converge and guide the light emitted by the LED beads. Compared to a flat glass shell, the arc-shaped glass allows the light to be directed more concentratedly in a specific direction, enhancing the visibility of the measuring beacon. This enables the total station to aim at the measuring beacon more clearly and accurately even at greater distances or in complex environments, thereby improving the measurement accuracy of engineering axis deviation.

[0012] In some embodiments, the LEDs are arranged along the length of the metal casing.

[0013] In the technical solution, the LED beads are arranged along the length of the metal shell, forming a continuous light-emitting line. This facilitates aiming and tracking by the total station, enabling the total station's crosshairs to be more accurately aligned with the optical axis center. This improves the alignment efficiency and reliability of the measurement results during the measurement process, and reduces measurement errors caused by unclear targets.

[0014] In some of these embodiments, the LEDs are located on the axis of the metal housing.

[0015] In some embodiments, the LED is connected to a cable, the other end of which is connected to a power source; a power interface is provided on the metal casing for the cable to pass through.

[0016] In the technical solution, by connecting the LED beads to the power supply via cables and setting a power interface for the cables to pass through the metal casing, it is not only convenient to connect the LED beads to an external power supply, ensuring that the LED beads emit light continuously and stably to meet the needs of long-term, continuous measurement work, but also the power supply of the LED beads can be flexibly changed in different engineering scenarios to ensure the smooth progress of the measurement work.

[0017] In some of these embodiments, the brightness of the LEDs is adjustable.

[0018] In this technical solution, the brightness of the LED beads is adjustable, allowing the measuring beacon to adapt to different measurement environments and distances. In dimly lit environments, the brightness can be increased to enhance visibility; in bright light or at close range, the brightness can be decreased to avoid interference with the total station measurement. By flexibly adjusting the LED beacon brightness, it is ensured that the measuring beacon can be optimally aimed by the total station under various conditions, improving the accuracy and reliability of measurements and expanding the applicability of the measuring beacon.

[0019] In some embodiments, the measuring beacon is mounted on a prism base on a tripod, and a prism is also mounted below the tripod. The prism is coaxially arranged with the metal housing and is used to check the verticality of the measuring beacon. The prism is located below the measuring beacon.

[0020] In this technical solution, the tripod provides stable support for the measuring beacon, ensuring its position remains fixed during measurement. The total station can check the verticality of the measuring beacon using a prism, preventing large deviations in the beacon's axis from affecting the accuracy of the project's axis deviation measurement. This allows the total station to more accurately determine the project's axis deviation. Furthermore, the total station can measure the project's axis deviation using a prism, and compare the axis deviation obtained through the prism with that obtained through measuring the beacon to improve measurement accuracy and precision.

[0021] In some embodiments, the prism base has a protrusion, and one end of the metal housing in the length direction has a mounting hole for inserting the protrusion so that the measuring beacon is mounted on the prism base.

[0022] In some embodiments, the mounting holes are located on the axis of the metal housing and are arranged along the axial direction of the metal housing.

[0023] In the technical solution, when the measuring beacon is installed, the central axis of the measuring beacon can be better aligned with the support axis of the control point, reducing the tilting or offset of the beacon caused by installation, providing a more accurate measurement target for the total station, and helping to improve the measurement accuracy of the engineering axis deviation.

[0024] In some embodiments, the metal casing has an insertion hole on the side opposite to the glass casing, and the insertion hole communicates with the mounting hole; a connector is provided in the insertion hole so that the connector is inserted into the mounting hole to lock the protrusion.

[0025] In the technical solution, an insertion hole communicating with the mounting hole is provided on the side of the metal shell away from the glass shell. The connector is inserted into the mounting hole through the insertion hole to lock the protrusion, thereby increasing the firmness of the connection between the measuring light and the tripod and preventing the measuring light from falling off the tripod due to accidental collision or vibration during the measurement process.

[0026] Based on the above technical solution, the measuring beacon in this embodiment of the utility model not only facilitates the measurement of the axis of the project using a total station, but also has a simple overall structure and is easy to set up. By placing the measuring beacon and the total station at two different traverse control points of the project, the total station measures the axis of the project through the measuring beacon, ensuring that the deviation of the axis of the project is within the allowable range, thereby ensuring the construction quality of the project.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] As attached Figure 1 As shown in an illustrative embodiment of the measuring beacon 1 of this utility model, the measuring beacon 1 is used in conjunction with a total station 4 to measure the axial deviation of the project. Specifically, the measuring beacon 1 is set at one traverse control point of the project, and the total station 4 is set at another traverse control point of the project, so that the total station 4 measures the axial deviation of the project by measuring the measuring beacon 1.

[0040] Since the measuring light 1 emits light, the total station 4 can clearly aim at the measuring light 1 during the measurement process to ensure the measurement accuracy and reliability of the engineering axis deviation, thus facilitating the measurement of the engineering axis deviation in underground engineering.

[0041] like Figure 2 and Figure 3 As shown, the measuring light 1 includes a metal housing 11, a glass housing 12, and an LED 13; the metal housing 11 has an opening along its length; the glass housing 12 is located at the opening of the metal housing 11; the glass housing 12 and the metal housing 11 together define a receiving cavity; the LED 13 is located in the receiving cavity, the LED 13 is mounted on the metal housing 11, and the light-emitting side of the LED 13 faces the glass housing 12.

[0042] In the aforementioned measuring beacon 1, the metal casing 11 and the glass casing 12 together form a receiving cavity, and the LED 13 is installed inside the receiving cavity. This provides a stable and protective installation environment for the LED 13, enabling it to work stably even in harsh environments (such as underground or underwater). The metal casing 11 is robust and durable, resisting external impacts, friction, and some harsh environmental factors, ensuring that the LED 13 works normally in complex engineering environments and extending the overall service life of the measuring beacon 1. The LED 13 emits light towards the glass casing 12, allowing the total station 4 to be clearly aimed, thereby improving the measurement accuracy and reliability of the engineering axis deviation.

[0043] like Figure 2As shown, the glass housing 12 is arc-shaped, and the center of the arc of the glass housing 12 is located inside the receiving cavity, so that the glass housing 12 can play a certain role in converging and guiding the light emitted by the lamp bead 13. Compared with the flat glass housing 12, the arc-shaped glass can make the light more concentrated and directed in a specific direction, enhancing the visibility of the measuring light 1, so that the total station 4 can aim at the measuring light 1 more clearly and accurately at a greater distance or in complex environments, thereby improving the measurement accuracy of the engineering axis deviation.

[0044] like Figure 2 As shown, the LED 13 is arranged along the length of the metal casing 11 so that the LED 13 forms a continuous light-emitting line, which facilitates the total station 4 to aim and track, and enables the crosshairs of the total station 4 to be more accurately aligned with the center of the optical axis, thereby improving the alignment efficiency and reliability of the measurement results during the measurement process and reducing measurement errors caused by unclear targets.

[0045] In some embodiments, the lamp bead 13 is an LED lamp bead, preferably with a diameter of 6mm, a rated power of 10W, and a rated voltage of 12V.

[0046] The LED bead 13 is connected to a cable. One end of the cable is connected to the LED bead 13, and the other end is connected to the power supply, so that the power supply can supply power to the LED bead 13 through the cable, thereby enabling the LED bead 13 to emit light continuously and stably, meeting the needs of long-term, continuous measurement work.

[0047] like Figure 3 As shown, a power interface 102 is provided on the metal casing 11. The power interface 102 is used for cables to pass through, which not only facilitates the connection of the LED bead 13 to an external power source, but also allows for flexible replacement of the power source of the LED bead 13 in different engineering scenarios, ensuring the smooth progress of the measurement work.

[0048] It should be noted that when the rated voltage of LED 13 is 12V, a power adapter can be installed on the connection circuit between LED 13 and the power supply to ensure that the voltage meets the requirements of LED 13.

[0049] In some embodiments, the LED 13 is soldered onto the metal housing 11.

[0050] The brightness of LED 13 is adjustable to allow the measuring beacon 1 to adapt to different measurement environments and distances. In dimly lit environments, the brightness of LED 13 can be appropriately increased to enhance visibility; in bright light or at close range, the brightness of LED 13 can be decreased to avoid excessive brightness interfering with the total station 4 measurement. By flexibly adjusting the brightness of LED 13, it can be ensured that the measuring beacon 1 can be optimally aimed by the total station 4 under various conditions, improving the accuracy and reliability of the measurement and expanding the applicability of the measuring beacon 1.

[0051] The LED 13 is located on the axis of the metal housing 11 so that the reflective lines generated by the LED 13 are arranged along the axis of the metal housing 11. It should be noted that the axis of the metal housing 11 is also the axis of the measuring light 1.

[0052] In practical applications, there will inevitably be an error between the setting position of the LED 13 on the metal housing 11 and the axis of the metal housing 11. The deviation should be controlled within 1mm to avoid reducing the measurement accuracy of the engineering axis deviation due to excessive deviation.

[0053] Since the axis of the metal casing 11 is set in the vertical direction, in order to prevent the axis of the measuring beacon 1 from deviating too much and affecting the measurement effect of the engineering axis deviation, this application sets a prism 3 on the tripod 2 and uses the prism 3 to check the verticality of the measuring beacon 1.

[0054] Specifically, the prism 3 is coaxially arranged with the metal housing 11, and the prism 3 is located below the measuring light 1, wherein the measuring light 1 is located above the tripod 2, and the prism 3 is located below the tripod 2.

[0055] The calibration method for measuring beacon 1 is as follows:

[0056] (1) Two cross-shaped measuring nails are laid on the ground to form two measuring points on the ground, and the distance between the two measuring points is greater than or equal to 100 meters.

[0057] (2) Based on the principle of optical alignment, tripods 2 are set up at the two measurement points respectively, and the total station 4 and the measuring light 1 are installed on the two tripods 2 respectively.

[0058] (3) Set up the prism 3 on the crosshair nail below the measuring light 1. Aim the center of the crosshair of the total station 4 at the center of the prism 3. Adjust the vertical fine adjustment screw of the total station 4 until the measuring light 1 is reached. Measure the axial deviation of the measuring light 1 according to the position of the vertical crosshair of the measuring light 1. It is strictly forbidden to adjust the horizontal fine adjustment screw of the total station 4.

[0059] It should be noted that since the prism 3 and the metal casing 11 are coaxially arranged in the vertical direction, the total station 4 can also measure the axis deviation of the project through the prism 3. By comparing and analyzing the axis deviation measured through the prism 3 with the axis deviation measured through the measuring beacon 1, the accuracy and precision of the measurement can be improved.

[0060] The measuring light 1 is mounted on the prism base of the tripod 2 so that the tripod 2 provides stable support for the measuring light 1, ensuring that the position of the measuring light 1 is fixed during the measurement process, while also ensuring that the measuring light 1 and the prism 3 are coaxially set. It should be noted that when the measuring light 1 is mounted on the tripod 2, the axis of the metal housing 11 is set in the vertical direction.

[0061] It should also be noted that the prism base has optical alignment, which allows the measuring beacon and the ground point to be set coaxially in the vertical direction.

[0062] like Figure 3 As shown, the metal casing 11 has a mounting hole 101 at one end along its length, and the prism base on the tripod 2 has a protrusion. The mounting hole 101 is used for inserting the protrusion so that the measuring light 1 and the tripod 2 are connected as a whole.

[0063] In some embodiments, the protrusion is provided with external threads, and the mounting hole 101 is provided with internal threads. The protrusion and the mounting hole 101 are connected by threads to increase the firmness of the measuring beacon 1 on the tripod 2.

[0064] Mounting hole 101 is located on the axis of metal housing 11 and is set along the axial direction of metal housing 11 so that when measuring light beacon 1 is installed, the central axis of measuring light beacon 1 can be better aligned with the support axis of tripod 2, reducing the tilting or offset of light beacon caused by installation, providing a more accurate measurement target for total station 4, and helping to improve the measurement accuracy of engineering axis deviation.

[0065] It should be noted that in practical applications, the position of the mounting hole 101 on the metal housing 11 will inevitably deviate from the axis of the metal housing 11. The deviation should be controlled within 1mm to avoid affecting the measurement accuracy of the axis deviation of the project due to excessive deviation.

[0066] In some embodiments, the metal housing 11 has an insertion hole on the side opposite to the glass housing 12, and the insertion hole communicates with the mounting hole 101; a connector 14 is provided in the insertion hole so that the connector 14 is inserted into the mounting hole 101 to lock the protrusion.

[0067] By providing an insertion hole on the side of the metal housing 11 away from the glass housing 12 that communicates with the mounting hole 101, the connector 14 extends into the mounting hole 101 through the insertion hole to lock the protrusion, thereby increasing the firmness of the connection between the measuring light 1 and the tripod 2 and preventing the measuring light 1 from falling off the tripod 2 due to accidental collision or vibration during the measurement process.

[0068] The method for measuring the deviation of the engineering axis is as follows:

[0069] (1) Set up the total station 4 and the measuring light 1 on two different traverse control points and adjust the level bubble to be centered;

[0070] (2) Adjust the brightness of measuring lamp 1 according to the sight distance of total station 4 to make the image clear;

[0071] (3) Adjust the horizontal fine-motion screw of the total station 4 until the measuring light 1 is reached, so that the vertical crosshair of the total station 4 coincides with the measuring light 1. Read the horizontal angle of the total station 4 and perform multiple observations in accordance with the requirements of the "Engineering Surveying Standard" (GB50026-2020).

[0072] It should be noted that the control points for traverse lines are common knowledge in this field and will not be elaborated upon further.

[0073] The aforementioned measuring beacon 1 not only facilitates the measurement of the project's axis by the total station 4, but also features a simple overall structure and is easy to set up. By placing the measuring beacon 1 and the total station 4 at two different traverse control points of the project, the total station 4 measures the project's axis using the measuring beacon 1, ensuring that the axis deviation is within the allowable range and thus guaranteeing the construction quality of the project.

[0074] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0075] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
