The L-shaped connecting rod 101 adopts a vertically bent steel pipe. The mounting plate 102 is fixed to the left end of the horizontal section of the L-shaped connecting rod 101 by welding. The mounting plate 102 is fixed to the wall of the building 9 by screws or anchor rods. The vertical section of the L-shaped connecting rod 101 extends vertically downward.

[0035] Further, combined with Figure 1 and Figure 2 As shown, the detection assembly 2 includes three parts: a conical cylinder 201, a cylindrical cylinder 202, and a translation detection base 203. The conical cylinder 201 is thin at the top and thick at the bottom, the lower end of the cylindrical cylinder 202 is fixedly connected to the upper end of the conical cylinder 201, and the interiors of the cylindrical cylinder 202 and the conical cylinder 201 are connected.

[0036] Combination Figure 1 and Figure 2As shown, the translation detection base 203 is a flat plate, and the conical cylinder 201 is placed on the top of the translation detection base 203. The conical cylinder 201 can move on the top surface of the translation detection base 203 under the driving of external force.

[0037] In some implementations of this embodiment, in order to detect the settlement of the building 9, a universal ball 3 is installed in the cylindrical body 202, the diameter of the universal ball 3 is the same as the inner diameter of the cylindrical body 202, the top center of the universal ball 3 is fixedly connected to the lower end of the vertical section of the L-shaped connecting rod 101, and the light beam generator 301 is embedded and installed in the bottom center of the universal ball 3, and the light emitted by the light beam generator 301 is on the same axis as the center of the vertical section of the L-shaped connecting rod 101.

[0038] Furthermore, a base plate 4 is installed at the bottom of the conical cylinder 201, combined with Figure 2 and Figure 4 As shown, the substrate 4 is a circular plate, and a plurality of photosensitive sensors 401 are installed on the top surface of the substrate 4 to detect the irradiation of light. A plane coordinate system is established with the center of the substrate 4 as the origin, and the coordinates of each photosensitive sensor 401 are stored in the processor and the server.

[0039] Combination Figure 2 As shown, the center of the substrate 4 is vertically aligned with the center of the universal ball 3, and a distance measuring head 10 is installed at the center of the substrate 4. The distance measuring head 10 adopts an infrared distance measuring probe in the prior art, and the distance measuring head 10 can emit a vertical upward distance measuring light.

[0040] In some implementations of this embodiment, combined with Figure 1 , Figure 3 and Figure 5 As shown, a circular substrate 25 is mounted on the top surface of the translation detection base 203, a plurality of photosensitive sensors 2501 are mounted on the top surface of the substrate 25, a light beam generator 204 is mounted on the bottom of the conical cylinder 201, the light beam generator 204 emits light vertically, and the photosensitive sensors 2501 can detect the light beam generator 204. Similarly, a plane coordinate system is established with the center of the substrate 25 as the origin, and the coordinates of each photosensitive sensor 2501 are stored in the processor and the server.

[0041] A solar energy mechanism 8 is installed on the wall of the building 9. The solar energy mechanism 8 includes a series of components such as photovoltaic panels and batteries. The photovoltaic panels convert solar energy into electrical energy and store it in the batteries. The batteries provide electrical energy for the beam generator 1 301, the photosensitive sensor 1 401, the distance measuring head 10, the beam generator 2 204, and the photosensitive sensor 2 501, so that the system can operate for a long time under independent power supply and realize all-weather detection of settlement.

[0042] It should be noted that the light beam generator 1 301, the light sensor 1 401, the light beam generator 204, the light sensor 2 501 and the distance measuring head 10 are all connected to the controller through wires, and the controller is connected to a GPRS communication module. The GPRS communication transmits data to the cloud server, so that the cloud server can analyze and process the data. In other embodiments, the central processing unit of the controller can also be used to analyze and process the data.

[0043] In some implementations of this embodiment, in order to reduce the friction resistance between the translation detection base 203 and the conical cylinder 201, a universal ball 205 is installed at the bottom of the conical cylinder 201 to convert the sliding friction into rolling friction. In addition, the translation detection base 203 is provided with a slide groove 2032 surrounding the groove 2031, and the ball 205 rolls on the bottom of the slide groove 2032. The translation of the building 9 can be measured more accurately.

[0044] In order to extend the service life of the ball 205, the ball 205 is subjected to a blueing treatment, and lubricating oil is applied to the surface of the ball 205 to further reduce friction.

[0045] In some implementations of this embodiment, in order to support the translation detection base 203, a fixed pile 6 is installed at the bottom of the translation detection base 203, and the fixed pile 6 is welded and fixed to the bottom of the translation detection base 203. During installation, the top surface of the translation detection base 203 is leveled by a level meter. The fixed pile 6 is provided with a steel pipe inserted into the ground, and concrete is poured in the steel pipe to provide fixed stability and reduce the possibility of settlement of the fixed pile 6.

[0046] Furthermore, in order to protect the building settlement detection device, combined with Figure 1 As shown, a box-shaped housing 7 is installed on the wall of a building 9, and the housing 7 covers the installation component 1, the detection component 2, etc. A through hole 701 is opened at the bottom of the housing 7, and the fixing pile 6 passes through the through hole 701. The diameter of the through hole 701 is larger than the diameter of the fixing pile 6, so as to prevent the housing 7 from causing the fixing pile 6 to tilt due to the tilt of the building 9.

[0047] In order to prevent mosquitoes from entering and affecting the measurement, a rope net 702 is installed in the through hole 701. The outer circle of the rope net 702 is fixedly connected to the hole wall of the through hole 701, and the inner circle of the rope net 702 is fixedly connected to the outer wall of the fixed pile 6. The rope net 702 can be stretched, so it does not affect the verticality of the fixed pile 6.

[0048] Embodiment 2: This embodiment provides a detection method, which uses the building settlement detection device of embodiment 1 and also includes the following method: installing the building settlement detection device on the wall of the building 9 that needs to be detected.

[0049] When the building 9 sinks, there are three main types of sinking, including vertical descent, horizontal displacement and tilt. When the building 9 sinks vertically, the universal ball 3 also sinks vertically in the cylindrical body 202. When the building 9 sinks horizontally, the conical body 201 also moves horizontally in the translation detection base 203. When the building 9 sinks, the universal ball 3 also rotates to a corresponding tilt angle. The light beam generator 1 301, the light sensor 1 401, the light beam generator 2 204, the light sensor 2 501 and the distance measuring head 10 can be set to measure once every half an hour or one hour.

[0050] For example, combining Figure 6 As shown in the figure, it is a schematic diagram after the settlement occurs. The vertical arrow indicates the ranging direction of the ranging head 10. The value of the distance of the universal ball 3 measured by the ranging head 10 last time is K1, and the vertical value of the distance of the universal ball 3 measured this time is K2. Therefore, the cloud server calculates the vertical descent distance according to the formula K3=K2-K1.

[0051] The beam generator 301 emits a beam of infrared light ( Figure 6 The cloud server detects the coordinates of the photosensitive sensor 401 from the memory, and combines the coordinates of the photosensitive sensor 401 recorded in the last detection, and uses the distance formula between two points and the trigonometric function formula to calculate the distance K4 to the center and the azimuth θ1 (for example, 10° west of due north), and then the cloud server calculates the distance K4 to the center according to the formula The angle of the inclination angle θ2 is calculated.

[0052] Combination Figure 3 As shown, the second beam generator 204 emits a beam of infrared light, and a second photosensitive sensor 501 detects the irradiation of the infrared light. The cloud server detects the coordinates of the second photosensitive sensor 501 from the memory, and combines the coordinates of the second photosensitive sensor 501 recorded in the last detection, and uses the distance formula between two points and the trigonometric function formula to calculate the distance K5 to the center and the azimuth θ3 (for example, 15° west of due north).

[0053] Finally, the monitoring system (computer) in the control room downloads the vertical descent distance K3, tilt angle θ2 and tilt direction (e.g. 10° west of due north), horizontal displacement distance K5 and displacement direction (e.g. 15° west of due north) obtained from the cloud server. If the monitoring system (computer) detects that the threshold is exceeded, a risk warning will be issued.
