Description

Technical Field

[0001] The invention relates to the technical field of building structure detection, and in particular to an automatic detection instrument for building structures. Background Art

[0003] Buildings and structures have a certain service life. During the use of buildings and structures, they need to be inspected regularly to understand the health of the buildings and prevent property losses and harm to people’s lives due to poor local quality or damage.

[0004] When inspecting buildings, the main focus is on checking whether there are cracks, whether there are cracks, deformation or other damage in the main load-bearing components, such as beams, columns, slabs, walls, etc., and evaluating the performance of various materials that make up the building, including the aging, corrosion or degradation of concrete, steel, masonry, wood, etc., and checking whether there are leakage, water accumulation or moisture problems, which may cause structural damage or mildew, as well as hollowing. At present, the inspection of buildings is mainly carried out by drone appearance camera inspection, or inspection personnel climb on the buildings to conduct inspections using various instruments. When using drone appearance camera inspection, the inspection of hollowing, material performance, etc. is not thorough. When using inspection personnel to climb on the building for inspection, the inspection accuracy is high, but the inspection efficiency is too low. When a large number of buildings need to be inspected, it is difficult to complete the inspection quickly and effectively.

[0005] Therefore, those skilled in the art are committed to developing an automated building detection instrument that can not only improve the detection accuracy of buildings, but also improve the detection efficiency of buildings. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide an automatic building detection instrument, which can not only improve the detection accuracy of buildings, but also improve the detection efficiency of buildings. The technical solution of the present invention to solve the above technical problems is as follows: An automatic detector for building structures, comprising UAV components; A mounting frame, the mounting frame is located at the lower side of the drone assembly, a camera assembly and an infrared assembly are mounted on the mounting frame, and a pressure gauge and a sampling assembly are also mounted in the mounting frame; A first suction cup assembly, the first suction cup assembly on both sides being mounted on both sides of the mounting frame; A second suction cup assembly, wherein two of the second suction cup assemblies are located on both sides of the mounting frame, and a lifting assembly is installed between the second suction cup assembly and the mounting frame; A control component, wherein the control component has a storage module, and the control component is electrically connected to the camera component, the infrared component, the pressure gauge, the sampling component, the first suction cup component, the second suction cup component and the lifting component.

[0008] The beneficial effects of adopting the above scheme are: during the flight of the installation frame driven by the drone component, the camera component and the infrared component detect the appearance and infrared information of the building, and transmit the detection information to the storage module; After reaching the set position, the control component controls the first suction cup component and the second suction cup component to extend and adsorb on the structure, so that the pressure gauge can detect the structure, and the sampling component can also take samples from the surface of the structure for further analysis; At corners or places that are inconvenient for drone components to reach, the cooperation of the first suction cup assembly, the second suction cup assembly and the lifting assembly allows the installation frame to crawl and move on the surface of the building, thereby facilitating the detection of various positions of the building and improving the detection accuracy and efficiency.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the adsorption ends of the first suction cup assembly and the second suction cup assembly are both connected to a vacuum assembly, and the vacuum assembly is electrically connected to the control assembly.

[0011] The beneficial effect of adopting the above further scheme is that the vacuum assembly is connected to the adsorption ends of the first suction cup assembly and the second suction cup assembly, so that the suction cup assembly has sufficient adsorption force to keep the drone assembly and the mounting frame stable.

[0012] Furthermore, the sampling assembly includes a sampling drill bit, a support block, a thrust assembly and a power assembly. The sampling drill bit has a sampling cavity, and the end of the sampling drill bit has drill teeth. The sampling drill bit is installed on the support block through a mounting bearing. The sampling drill bit is also connected to the thrust assembly and the power assembly.

[0013] The beneficial effect of adopting the above further scheme is that the rotation of the power component drives the sampling drill bit to rotate, and the thrust component pushes the drill bit to move, so that the drill teeth drill samples on the surface of the building and temporarily store them in the sampling cavity.

[0014] Further, the thrust assembly includes a first electromagnet, a second electromagnet and a return spring, the first electromagnet is installed on the support block, the second electromagnet is installed on the sampling drill bit, the return spring is sleeved on the outer layer of the sampling drill bit and the two ends of the return spring are respectively abutted against the first electromagnet and the second electromagnet, and the first electromagnet and the second electromagnet are electrically connected to the control assembly.

[0015] The beneficial effect of adopting the above further scheme is that when the control component controls the power component to rotate, it simultaneously controls the first electromagnet and the second electromagnet to be energized, so that the first electromagnet and the second electromagnet attract each other and compress the reset spring, thereby pushing the drill bit to move along the axial direction of the mounting bearing to drill samples on the surface of the building.

[0016] Furthermore, a transmission groove is provided on the outer wall of the sampling drill bit and on a side opposite to the drill teeth, a rotating shaft is installed at the output end of the power component, a transmission pin is provided on the rotating shaft, and the transmission pin is located in the transmission groove.

[0017] The beneficial effect of adopting the above further solution is that the rotation of the power assembly drives the rotation shaft and the transmission pin to rotate, thereby driving the sampling drill bit to rotate, ensuring that the power assembly and the sampling drill bit rotate synchronously when the sampling drill bit moves horizontally.

[0018] Further, the first suction cup assembly includes a first suction cup, the first suction cup is installed at the output end of the first telescopic assembly, and the first telescopic assembly is connected to the control assembly; The second suction cup assembly includes a second suction cup, the second suction cup is installed at the output end of the second telescopic assembly, and the second telescopic assembly is connected to the control assembly.

[0019] The beneficial effect of adopting the above further solution is that the telescopic component drives the suction cup component to move, which is conducive to the suction cup component being adsorbed on the surface of the building, and is conducive to subsequent sampling or pressure gauge detection.

[0020] Furthermore, the first suction cup and the second suction cup each have a through hole, and the through hole is connected to the suction end of the vacuum assembly.

[0021] The beneficial effect of adopting the above further solution is that the vacuum pumping component continuously draws a vacuum so that the suction cup component always has a suitable vacuum degree, which helps the suction cup to be adsorbed on the building to avoid falling off.

[0022] Further, the lifting assembly includes a lifting screw, a lifting motor, a lifting plate and a guide block, the lifting screw is installed in the installation frame through a screw mounting seat, one end of the lifting screw is connected to the lifting motor, the lifting motor drives the lifting screw to rotate, the lifting screw outer sleeve is provided with the lifting plate, the lifting plate has a threaded hole matched with the lifting screw, and the lifting plate is connected to the second suction cup assembly; The guide blocks are also installed at both ends of the lifting plate, and the inner side wall of the installation frame is also provided with a guide groove that cooperates with the guide blocks.

[0023] The beneficial effect of adopting the above further solution is that the control component controls the lifting motor to rotate so that the second suction cup component moves up and down, which is beneficial for the installation frame to crawl and move on the surface of the building.

[0024] Furthermore, the camera component includes a high-speed camera, the infrared component includes an infrared detector, and the high-speed camera and the infrared detector are both electrically connected to the control component.

[0025] The beneficial effect of adopting the above further scheme is: the high-speed camera collects the surface information of the building, the infrared detector collects the infrared information of the building, and transmits the various information to the storage module for storage, which is conducive to further analysis and detection later.

[0026] Furthermore, the pressure gauge is a concrete pressure gauge, and the concrete pressure gauge is electrically connected to the control component.

[0027] The beneficial effect of adopting the above further solution is that the concrete pressure gauge is used to detect the internal pressure of the building structure. BRIEF DESCRIPTION OF THE DRAWINGS
