Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping data acquisition technology, specifically a multispectral data acquisition instrument for surveying historical buildings. Background Technology

[0002] The multispectral data acquisition instrument is a distributed network automated data acquisition system used in conjunction with independently developed monitoring cloud software. It is designed for real-time automatic data acquisition, storage, transmission, calculation, reporting, and early warning of sensor signals in various geotechnical engineering and building structure safety monitoring projects. It provides engineering construction and operation managers with data support and judgment criteria related to the project's current status and safety. It works by acquiring the intensity of light signals at different locations and then performing a series of analyses and applications.

[0003] The prior art, disclosed in CN220453202U, provides a surveying data acquisition instrument, relating to the field of surveying data acquisition technology. It includes an operating table with three evenly distributed hinge seats fixed at its bottom. Each of the three hinge seats has a rotatable support cone. A rotating assembly is located at the top of the operating table, facilitating adjustment of the data acquisition angle according to user needs. The rotating assembly includes a horizontal acquisition component, further facilitating adjustment of the data acquisition instrument's horizontal angle and improving data acquisition accuracy. This invention utilizes two cranks to raise or lower nylon ropes inside two connecting cylinders. Due to the gravity of the data acquisition instrument, the instrument at the top of the base tends to be horizontal, preventing horizontal surveying positions from affecting data acquisition accuracy. Simultaneously, rotating the shaft rotates the data acquisition instrument at the top of the placement plate, allowing for easy adjustment of the data acquisition angle according to user needs and expanding its applicability.

[0004] The aforementioned patent primarily relies on the gravity of the data acquisition device, along with two nylon ropes, to maintain its horizontal position. However, this method of leveling the data acquisition device lacks subsequent securing mechanisms. The device is supported solely by the nylon ropes, making it prone to swaying under even slight external forces. This hinders user convenience for surveying operations and reduces the practicality of the surveying data acquisition device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multispectral data acquisition instrument for historical building surveying, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multispectral data acquisition instrument for historical building surveying, comprising a support assembly, a limiting assembly fixedly installed on the top of the support assembly, and an acquisition assembly disposed within the limiting assembly. The acquisition assembly includes a placement body located on top of the support assembly, a semicircular groove formed at the center of the top of the placement body, a semicircular block movably installed within the semicircular groove, a multispectral data acquisition device for surveying fixedly installed on the top of the semicircular block, strips fixedly installed on both sides of the multispectral data acquisition device, an electric actuator fixedly installed downwards on one side of the strip of the multispectral data acquisition device, and a multi-directional suction cup fixedly installed at the bottom of the electric actuator for fixing the semicircular block after rotation. The multi-directional suction cup fixedly installed at the bottom of the electric actuator for fixing the semicircular block after rotation ensures that the semicircular block can be firmly fixed to the placement body by the multi-directional suction cup after rotation, thereby improving the stability of the internal structure of the multispectral data acquisition instrument for historical building surveying during operation.

[0007] Furthermore, a microcontroller is fixedly installed on the strip of the semicircular block near the electric actuator, and the microcontroller is electrically connected to the electric actuator. This electrical connection allows the microcontroller to directly control the extension and retraction of the electric actuator, enhancing the intelligence of the multispectral data acquisition instrument used for historical building surveying.

[0008] Furthermore, a counterweight is fixedly installed on the strip on the side of the semicircular block away from the electric actuator to keep the semicircular block balanced.

[0009] Furthermore, the limiting component includes a mounting chassis fixedly mounted on the support component, a mounting shaft fixedly mounted on the top of the mounting chassis, and a limiting top plate fixedly mounted on the end of the mounting shaft away from the mounting chassis. The limiting top plate is used to limit the vertical movement of the multispectral data acquisition device.

[0010] Furthermore, the support assembly includes a mounting plate, a connecting strip is fixedly mounted on the lower end of the mounting plate, and a lower plate is fixedly mounted on the end of the connecting strip away from the mounting plate. The support assembly also includes multiple adjustment components, which are movably located between the mounting plate and the lower plate.

[0011] Furthermore, the adjustment assembly includes a rotatable sleeve shaft located within the lower plate, with a limit plate fixedly installed at the upper end of the sleeve shaft, the limit plate being used to limit the vertical movement of the sleeve shaft.

[0012] Furthermore, the sleeve is U-shaped, with a through shaft fixedly mounted on it. A support rod is rotatably mounted on the through shaft, and the support rod is located within the inner groove of the U-shaped sleeve. This placement of the support rod within the inner groove allows the user to adjust its movement according to specific usage conditions, enhancing the ease of use of the multispectral data acquisition instrument for historical building surveying. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention places the multispectral data acquisition device on the top of a semicircular block, which can rotate smoothly within a semicircular groove. This allows the multispectral data acquisition device to be rotated to a horizontal position at all times during use. When the multispectral data acquisition device is rotated to a horizontal position, the user can use an electric push rod to move the multi-directional suction cup downwards to fix the horizontal multispectral data acquisition device, thereby improving the practicality of the multispectral data acquisition instrument for historical building surveying.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below. A multispectral data acquisition instrument for surveying historical buildings includes a support assembly 1. A limiting assembly 3 is fixedly installed on the top of the support assembly 1. A data acquisition assembly 2 is disposed within the limiting assembly 3. The data acquisition assembly 2 includes a placement body 22 located on top of the support assembly 1. A semicircular groove 21 is formed at the center of the top of the placement body 22. A semicircular block 23 is movably installed in the semicircular groove 21. A multispectral data acquisition device 25 for surveying is fixedly installed on the top of the semicircular block 23. Strips are fixedly installed on both sides of the multispectral data acquisition device 25. An electric actuator 27 is fixedly installed downward on one side of the strip of the multispectral data acquisition device 25. A multi-directional suction cup 28 for fixing the semicircular block 23 after rotation is fixedly installed at the bottom of the electric actuator 27. A microcontroller 26 is fixedly installed on the strip of the semicircular block 23 near the electric actuator 27. The microcontroller 26 is electrically connected to the electric actuator 27. A counterweight 24 for keeping the semicircular block 23 balanced is fixedly installed on the strip of the semicircular block 23 away from the electric actuator 27. The limiting assembly 3 includes... The support assembly 1 includes a mounting base 33 fixedly mounted on the support assembly 1. A mounting shaft 32 is fixedly mounted on the top of the mounting base 33. A limiting top plate 31 is fixedly mounted on the end of the mounting shaft 32 away from the mounting base 33. The limiting top plate 31 is used to limit the vertical movement of the multispectral data acquisition unit 25. The support assembly 1 includes a mounting plate 12. A connecting strip 11 is fixedly mounted on the lower end of the mounting plate 12. A lower plate 14 is fixedly mounted on the end of the connecting strip 11 away from the mounting plate 12. The support assembly 1 also includes multiple adjustment components. 13. The adjusting component 13 is movably located between the mounting plate 12 and the lower plate 14. The adjusting component 13 includes a rotatable sleeve shaft 131 located in the lower plate 14. A limit plate 134 is fixedly installed on the upper end of the sleeve shaft 131. The limit plate 134 is used to limit the up and down movement of the sleeve shaft 131. The sleeve shaft 131 is U-shaped. A through shaft 133 is fixedly installed on the sleeve shaft 131. A support rod 132 is rotatably installed on the through shaft 133. The support rod 132 is located in the inner groove of the U-shaped sleeve shaft 131.

[0025] The multispectral data acquisition unit 25 works by separating and capturing light of different wavelengths through different filters and sensors. These filters can be arranged in a matrix or rotated to change the bands. Thus, the acquisition unit records the information of each band and generates multiple images. Then, these independent images are combined together through image fusion technology to form the final multispectral image.

[0026] Since the semicircular block 23 is located within the semicircular groove 21 and the weights of the counterweight 24 and the electric push rod 27 are the same, when the entire multispectral data acquisition instrument for historical building surveying tilts during use, the semicircular block 23 will rotate within the semicircular groove 21 due to its own gravity and the balancing weights of the electric push rod 27 and the counterweight 24, eventually reaching a horizontal state. This also helps to level the multispectral data acquisition unit 25. Furthermore, the limiting effect of the limiting top plate 31 ensures that the semicircular block 23 moving within the semicircular groove 21 will not leave the semicircular block 23, thus improving the practicality of the multispectral data acquisition instrument for historical building surveying.

[0027] The working principle of the microcontroller 26 can be divided into four basic steps: input, processing, output, and feedback. First, the microcontroller 26 receives input signals from external devices or users, such as button presses or sensor detection information. Next, the microcontroller 26 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of external devices. Therefore, the microcontroller 26 can directly control the operation of the electric actuator 27. Since the multi-directional suction cup 28 is a suction cup that can be attracted in multiple directions, when the electric actuator 27 moves downward with the multi-directional suction cup 28, it can fix the rotated semi-circular block 23, thus improving the safety of the multispectral data acquisition instrument for historical building surveying.

[0028] Since the sleeve shaft 131 can be rotated at the upper limit on the lower plate 14 by the limiting plate 134, and the support rod 132 can be rotated by the through shaft 133, the user can adjust the entire adjustment assembly 13 according to the specific usage situation, which improves the practicality of the multispectral data acquisition instrument for historical building surveying.

[0029] It should be noted that the electrical components and control components in this application are all connected to an external controller and are all existing technologies. This application has not improved them and does not affect the integrity of this application. Furthermore, the parts not involved or not disclosed in detail are the same as or implemented using existing technologies.

[0030] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the multispectral data acquisition instrument for historical building surveying are fixed by threads. To allow for a more intuitive observation of the technical features, the bolt connections are appropriately concealed in the diagram. When using the multispectral data acquisition instrument for historical building surveying, the user places it at the location where the historical building is being surveyed. If this location is not horizontal, the entire instrument will tilt. However, the semicircular block 23 will rotate within the semicircular groove 21 according to its own gravity and the relationship between the counterweights on both sides, eventually leveling the area. At this point, the user uses the microcontroller 26 to extend the electric push rod 27 downwards, and in conjunction with the multi-directional suction cup 28, fix the multispectral data acquisition device 25. This ensures that the multispectral data acquisition device can be fixed horizontally during use. When subjected to slight external force, the multispectral data acquisition device 25 will not rotate or shift, improving the practicality of the instrument.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
