Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a convenient and sustainable detection and observation device for the overall tilt of a building. Background Technology

[0002] Building tilt refers to the structural leaning of a building. If not addressed promptly, it can severely compromise the building's safety and stability. Therefore, timely measurement and monitoring of building tilt during or after construction is crucial. Commonly used methods for measuring building tilt include:

[0003] 1. Level Method: This method involves installing a level to measure the tilt angle of a building. The level is placed at different locations on the building, and the levelness values ​​at each location are recorded. These values ​​are then compared and calculated to determine the direction and angle of the building's tilt.

[0004] 2. Inclinometer Method: This method involves installing an inclinometer to measure the building's tilt angle and direction. The inclinometer is placed at different locations on the building, and the measurements at each location are recorded. These measurements are then compared and calculated to determine the building's tilt.

[0005] 3. Total Station Method: By using a total station, various parameters of a building, such as its tilt angle, tilt direction, and height, can be measured. A total station can quickly acquire the three-dimensional coordinate data of a building and process the data to produce a detailed analysis report on the building's tilt.

[0006] 4. Laser Scanning Method: By using a laser scanning instrument, high-precision three-dimensional measurements of buildings can be performed. The laser scanner can scan the point cloud data of the building surface, process the data, and generate a detailed analysis report on the building's tilt.

[0007] Before conducting measurements using the methods described above, thorough preparation is required, along with the selection of appropriate instruments and tools. The operation is relatively complex and must be performed and analyzed by professionals to ensure the accuracy and reliability of the measurement results. Consequently, commonly used methods may require the cooperation of various equipment and professional technicians. The complex operation methods can only be carried out by professional technicians periodically or in planned sessions, making it impossible to conduct continuous and convenient tilt observations of buildings.

[0008] In the prior art, Chinese patent application number CN2020219035395 discloses a building tilt detector, including an instrument body, a tilt detection mechanism, a support component, and a support cylinder. The support component is fixedly connected to the bottom periphery of the instrument body, and the support cylinder is fixedly connected to the top periphery of the support component. A top fixing ring is fixedly connected to the top middle part of the support component, and a bottom fixing ring is fixedly connected to the bottom middle part of the support component. The tilt detection mechanism is fixedly connected to the top middle part of the instrument body. The tilt detection mechanism can detect the tilt angle of a building. By setting a cone block and an infrared laser pointer, it uses the principle that gravity is always vertically downward to check the tilt of the building. In addition, the cavity is set to store water, which reduces the influence of external shaking on the cone block and the infrared laser pointer, thereby improving the accuracy of building tilt detection. While the aforementioned technical features can obtain relatively accurate building tilt detection values, the structure employed has shortcomings. First, the laser pointer shines downwards, and the reading is difficult to obtain from the bottom. Second, while the internal cavity filled with water is intended to reduce the impact of external shaking on the infrared laser pointer, the light still refracts in the water, leading to inaccurate readings. Furthermore, the wired power supply and manual intervention for reading can affect the position of the top spherical block, also causing inaccurate values. Therefore, the above technical solutions cannot effectively obtain accurate building tilt values ​​and cannot meet the requirements for high-precision measurement.

[0009] Therefore, the current building tilt detectors are inaccurate, difficult to read, and not perfect enough to meet the industry's high-precision requirements. Thus, designing a device for building tilt detection that can accurately measure the tilt of multiple sides of a building without the need for professional personnel, can monitor for a long time, and can reduce human resources and energy consumption is an urgent issue that is of great significance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The following description, with reference to the accompanying drawings, further illustrates a convenient, sustainable detection and observation device for overall building tilt according to this utility model:

[0035] like Figure 1-9 The device shown is a convenient building tilt detection and observation device, including a main box 1, which is a quasi-cylindrical box with a hollow interior. The bottom of the main box 1 is evenly provided with four sets of adjustable feet 11, which can adjust the level of the box. A transparent hemispherical cover assembly 2, a measuring assembly 3, and an electrical control assembly 4 installed on the outside of the main box 1 are also installed on the main box 1. The measuring assembly 3 is located at the upper inside of the main box 1. The measuring assembly 3 includes a cross-shaped bracket 31 and a suspended ball 32 installed on the cross-shaped bracket 31. The cross-shaped bracket is horizontally fixed on the inner wall of the main box or can be placed inside the main box through a stop (not shown). The cross-shaped bracket is detachable and can be designed with different installation methods according to needs. The cross-shaped bracket is perpendicular to the central axis of the main box. A hemispherical arc groove 33 adapted to the suspended ball 32 is provided at the center of the cross-shaped bracket 31. At the same time, a servo motor 311 is also provided on the cross-shaped bracket 31 near the transparent hemispherical cover assembly.

[0036] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the suspended ball 32 is installed inside the hemispherical arc groove 33. The structure inside the hemispherical arc groove 33 is adapted to half of the spherical part of the suspended ball 32, allowing the suspended ball to move within the hemispherical arc groove 33. The materials of the suspended ball and the hemispherical arc groove are made of a low-friction material to reduce movement resistance. A suspended ball retaining ring 332 is provided on the upper part of the hemispherical arc groove 33 to prevent the suspended ball from falling off. A laser pointer mounting post 36 is vertically mounted on the upper part of the suspended ball 32 and located on the central axis of the suspended ball 32. A vertical swing center rod 37, symmetrical to the laser pointer mounting post 36, is provided at the bottom of the suspended ball 32. The swing center rod 37 is connected to the suspended ball 32 via the center rod screw post 5, which facilitates disassembly and assembly. A laser pointer 361 is housed within the laser pointer mounting post 36. Under the action of the vertical swing center rod 37, the suspended ball 32 remains perpendicular to the central axis containing the laser pointer and the vertical swing center rod. To provide power to the laser pointer on the suspended ball, symmetrical positive and negative electrode plates 34 and 35 are provided on the inner wall of the hemispherical arc groove 33, separated by an insulator (not shown). The positive electrode plate is connected to the electronic control component 4 via a positive cable 6, and the negative electrode plate is connected via... The negative cable 7 is connected to the electronic control component 4; a positive electrode contact plate 321 corresponding to the positive electrode contact plate 34 and a negative electrode contact plate 322 corresponding to the negative electrode contact plate 35 are provided on the surface of the suspended ball 32 located in the hemispherical arc groove 33. The part of the suspended ball with positive and negative electrodes can contact the positive and negative electrode contact plates in the hemispherical arc groove 33 to achieve uninterrupted power supply. In order to ensure that the positive electrode contact plate 321 and the negative electrode contact plate 322 can always effectively contact the positive electrode contact plate 34 and the negative electrode contact plate 35 when the suspended ball rotates along the inner wall of the hemispherical arc groove, the positive electrode contact plate 321 and the negative electrode contact plate 322 rotate along the inner wall of the hemispherical arc groove. The surface of the suspended sphere is circularly laid out; the laser pointer 361 is electrically connected to the positive electrode power take-off piece 321 and the negative electrode power take-off piece 322. When the suspended sphere is stationary, the positive electrode power take-off piece 321 is electrically connected to the positive electrode piece 34 by contact, and the negative electrode power take-off piece 322 is electrically connected to the negative electrode piece 35 by contact, providing power to the laser pointer. Using electrode contact power supply can avoid the problem of the pulling force of the wire affecting the accuracy when using wired power supply; the bottom of the hemispherical arc groove 33 is provided with an opening 331 through which the vertical swing center rod 37 can pass. After the vertical swing center rod passes through the opening, it is located on the central axis of the main box.

[0037] like Figure 2 , Figure 10As shown, in actual use, the standard placement is as follows: the central axis of the hemispherical transparent cover 22, the center point of the cross-shaped bracket 31, the central axis of the suspended ball 32, the central axis of the hemispherical arc groove 33, the central axis of the laser pointer mounting column 36, the central axis of the laser pointer 361, and the central axis of the vertical swing center rod 37 are all on the central axis of the main housing 1. During use, the suspended ball 32 remains vertical and does not tilt because the hemispherical arc groove 33 is connected to the main housing 1 via the cross-shaped bracket 31. When the building tilts, the main housing 1 placed on it will tilt simultaneously. The hemispherical arc groove 33 is located at the center of the cross-shaped bracket 31, and the cross-shaped bracket 31 is horizontally installed on the main housing 1, with its center located on the central axis of the main housing. Therefore, when the main housing tilts, its central axis will also tilt, and the hemispherical arc groove 33 will tilt by the same angle. While the hemispherical arc groove 33 tilts, the suspended ball 32 will not tilt but will remain along... The ball rotates within the hemispherical arc groove 33. Because the coefficient of friction between the suspended ball 32 and the hemispherical arc groove 33 is low, and a vertical swing center rod 37 with a counterweight function is installed at the lower part of the suspended ball, the suspended ball will not tilt as the hemispherical arc groove tilts. Due to the limiting effect of the hemispherical arc groove, when the hemispherical arc groove tilts and swings, the suspended ball will remain vertical or, after the tilting process of the building slows down or stops completely, the suspended ball will return to the vertical position under the action of the vertical swing center rod. At this time, the laser pointer is powered on and emits a red laser vertically upward to irradiate the hemispherical transparent cover 22.

[0038] In this embodiment, as Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the transparent hemispherical cover assembly 2 includes a circular fixed edge 21 and a hemispherical transparent cover 22 mounted on the circular fixed edge 21 with numerical scales 221 on its arc surface. A rotating component 23 is provided between the hemispherical transparent cover 22 and the circular fixed edge 21. The rotating component 23 is fixedly installed along the bottom edge of the hemispherical transparent cover 22, and its diameter is consistent with the bottom diameter of the hemispherical transparent cover 22. A limiting groove 211 is provided on the circular fixed edge 21 corresponding to the rotating component 23, and the lower part of the rotating component 23 is provided with a groove 211 installed in the limiting groove 211. The limiting action mechanism 231 is fitted with a ceramic bushing 232 made of silicon nitride ceramic material with self-lubricating properties at its lower part; the rotating component 23 is provided with an action gear 233 corresponding to the servo motor 311 inside the rotating component 23. The servo motor can drive the rotating component to rotate on the circular fixed edge 21. The circular fixed edge 21 is detachably installed on the top of the main housing 1. The outer edge of the circular fixed edge 21 extends and is adapted to the bottom outer diameter of the hemispherical transparent cover 22. The diameter of the circular fixed edge 21 relative to the main housing 1 is larger than the diameter of the main housing.

[0039] In this embodiment, as Figure 2 , Figure 8 As shown, the center point of the hemispherical transparent cover 22, the center point of the cross-shaped bracket 31, and the central axis of the suspended ball 32 are all located on the central axis of the main box 1. All the device structures are located on the same axis, which can better obtain accurate measurement values.

[0040] In this embodiment, the electronic control component 4 includes a controller 41, a solar charging panel 42, and a battery 43 connected to the solar charging panel 42. The battery 43 is electrically connected to the positive electrode 34, the negative electrode 35, and the servo motor 311. The battery 43 is placed at the bottom of the main housing 1 to provide stability to the center of gravity of the housing. The controller 41 is externally mounted and is connected by a flexible cable. It will not affect the main housing during use. The controller can control the power supply and the rotation of the servo motor, thereby realizing the automatic rotation of the hemispherical transparent cover.

[0041] Operating Principle: For initial use, traditional equipment and instruments are used to measure the entire building to obtain initial data. The center point of the building is then located, and the device is placed near this center point. The power is turned on via the operator, and the suspended ball is placed into the hemispherical arc groove. Its positive and negative electrodes then contact the corresponding electrodes. The laser pointer draws power through these electrodes, emitting a red laser beam. The four adjustable feet at the bottom of the main unit are then adjusted. By observing the position of the laser beam projected onto the hemispherical transparent cover, the feet are adjusted to level the main unit. When the laser beam reaches the center point of the hemispherical transparent cover, the overall leveling of the unit is complete. Under the influence of the vertical swing center rod and gravity, the suspended ball remains vertical within the hemispherical arc groove. The laser pointer can rotate along the inner wall of the hemispherical groove. When the building tilts, the main box located at the center of the building tilts simultaneously. However, the suspended ball inside the main box remains vertically downward under the influence of the vertical swing center rod and gravity, while the laser pointer remains vertically upward. The servo motor, controlled by the controller, drives the hemispherical transparent cover to rotate. When the laser point emitted by the laser pointer coincides with the scale on the hemispherical transparent cover, the laser pointer stops, the scale is checked, and the tilt and angle values ​​of the building can be obtained. During the construction phase of the building, the laser pointer and servo motor can be powered by solar charging panels to ensure that the laser pointer always has a power supply for continuous observation during the construction phase. During the indoor construction phase inside the completed building structure, the built-in battery can provide continuous power, and the solar charging panel can charge the battery, enabling long-term continuous observation of the building's tilt.

[0042] This utility model discloses a convenient and sustainable monitoring and observation device for the overall tilt of a building. It includes a main housing, a transparent hemispherical dome assembly mounted on the main housing, a measuring assembly, and an electrical control assembly mounted on the outside of the main housing. Its structure is symmetrical and simple, its operation is intuitive and easy, and it can be operated by non-professionals. It is flexible in application, portable, and can be operated by a single person. Utilizing a vertically swinging central rod to achieve pendulum principle, and in conjunction with a laser pointer and the hemispherical transparent dome, the device is placed inside a building to achieve sustainable observation of the overall center point balance of large buildings and structures. It provides a convenient and sustainable observation method for judging the tilt degree and collapse risk of large buildings and structures. Through a combination of solar power and battery power, it can be placed inside buildings for long-term monitoring. The automatic rotation reduces the problem of inaccurate readings caused by manual touch during reading.
