Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a building surveying instrument with a multi-angle adjustment function. Background Art

[0002] Building measurement instruments are widely used in the fields of construction, engineering, topographic survey, etc., mainly used to measure parameters such as the height, distance, angle and inclination of buildings. There are many types of measuring instruments on the market, including total stations, laser rangefinders and electronic theodolites. However, traditional measuring instruments have problems such as single function, complex operation and limited measurement accuracy, which cannot meet the needs of modern construction projects for efficient, multi-functional and high-precision measurement. An existing angle-adjustable building measurement instrument (publication number: CN211291480U) has the following disadvantages and needs further improvement.

[0003] Traditional equipment can provide basic angle measurement, but lacks flexibility in multi-angle adjustment. The angle needs to be adjusted manually, and the measurement position is maintained by a fixed locking device. This method leads to angle errors in actual operation. Traditional theodolites require manual adjustment of horizontal and vertical angles, which depends on the operator's experience and skills. It is not only time-consuming, but also prone to human errors. In addition, the mechanical structure of the fixed locking device is prone to wear during frequent use, resulting in unstable locking, which further affects the accuracy of the measurement. Therefore, there is an urgent need for a building measuring instrument with multi-angle adjustment function. Traditional equipment relies on physical contact for measurement, which is cumbersome to operate and susceptible to environmental influences. When measuring the height of a building or crossing obstacles, common equipment such as steel rulers and measuring chains are not competent. Although traditional optical rangefinders do not require physical contact, their measurement range and accuracy are limited, and are greatly affected by factors such as light intensity and weather conditions. Optical rangefinders require operators to accurately aim within the line of sight, and long-term operation can easily lead to fatigue and reduce work efficiency. Moreover, since traditional distance measurement tools cannot display measurement data in real time, operators need to record and calculate repeatedly, which is not only time-consuming, but also increases the risk of errors. Therefore, there is an urgent need for a building measuring instrument with laser distance measurement function. Traditional equipment relies on bubble levels or simple mechanical sensors, which have low measurement accuracy and are greatly affected by human factors. These devices cannot record and store measurement data. Operators need to manually record the inclination value and then calculate the result. The process is not only cumbersome but also prone to errors. When measuring complex structures or a wide range of inclination angles, traditional levels cannot meet the needs of modern building measurement for high precision and versatility. Modern building construction and inspection require multi-point and multi-directional inclination measurements of structures to ensure the stability and safety of the structure. The limitations of traditional equipment in this regard make it difficult to meet the requirements of high precision and high efficiency. Therefore, there is an urgent need for a building measuring instrument with inclination test function. Utility Model Content

[0012] The utility model improves the multi-angle adjustment capability of the building measuring instrument by adding. The angle locking device ensures that the measuring position can be stably maintained after the angle is adjusted, which is crucial to improving the measurement accuracy. The angle locking device can adopt wear-resistant materials and mechanical design to ensure that the angle can be reliably fixed after long-term use. In addition, the introduction of the angle sliding wheel makes the angle adjustment of the measuring instrument in the horizontal and vertical directions smoother and more accurate. The angle sliding wheel is combined with a precise gear transmission system to ensure the flexibility and accuracy of the adjustment process, greatly reducing the workload and error possibility of the operator. The utility model can improve the distance measurement capability and operation convenience of the building measuring instrument by adding. The core components of the laser rangefinder include a laser transmitter and a receiver, which accurately measures the distance by emitting a laser beam to the target object and receiving the reflected signal. This non-contact measurement method overcomes many limitations of traditional physical contact measurement tools, is easier to operate and is not affected by environmental factors. When measuring the height of a building or crossing an obstacle, the laser rangefinder can easily complete the measurement task without the need for complicated operations such as a steel ruler or a measuring chain. Laser transmitters usually use semiconductor lasers, which can provide high-intensity and stable laser output to ensure the accuracy and reliability of measurement. The receiver uses a photoelectric detector, which can accurately capture the reflected signal and perform distance calculations, further improving the measurement accuracy. The introduction of the display screen allows the measurement data to be displayed in real time, and the operator no longer needs to record and calculate repeatedly, greatly improving work efficiency and accuracy. The utility model can enhance the inclination test capability and data management capability of the building measuring instrument by adding. The electronic level uses advanced MEMS sensors, which can provide high-precision horizontal and vertical inclination measurements. The introduction of the data recording unit allows the measurement data to be recorded and stored in real time, and the operator does not need to manually record the inclination value, simplifying the operation process and data management. Through the USB or Bluetooth interface, the data can be easily exported to an external device for further analysis and archiving, improving the utilization rate and work efficiency of the measurement data. The introduction of the display screen allows the inclination test results to be displayed intuitively, and the operator can view the measurement data and make adjustments in real time, further improving work efficiency and measurement accuracy.

[0051] The following is the specific technical logic implementation method of the innovative point of this utility model:

[0052] 1. Technical realization of multi-angle adjustment function

The overall design ensures that the system can work stably in various environments, whether it is measuring the height of a building or measuring tasks across obstacles, it can be easily handled.

[0056] 3. Technical implementation of the inclination test function

[0057] The utility model realizes high-precision inclination measurement and efficient data management by integrating an electronic level and a data recording unit in the inclination test function. The electronic level adopts advanced MEMS sensors, which can accurately measure the inclination in the horizontal and vertical directions.
