Description

Technical Field

[0001] The invention relates to infrared detection equipment for building hollowing, belonging to the technical field of building construction. Background Art

[0002] Building hollowing detection is an important part of ensuring the quality of the house. Hollowing refers to the hollowing phenomenon between the floor, wall, and ceiling decoration layer (plastering or pasting tiles) and the structural layer (concrete or brick wall) of the house due to loose pasting and bonding. The occurrence of hollowing is usually related to uneven proportions of cement mortar during construction, non-standard construction, and the influence of environmental factors. For hollowing problems found, they should be recorded in time and the relevant responsible parties should be notified for repair. Repair methods usually include removing the hollow part, re-plastering or pasting, etc. During the construction process, operations should be strictly carried out in accordance with construction specifications to ensure that the proportion of cement mortar is uniform and the construction standards are met to reduce the occurrence of hollowing. By selecting appropriate detection methods and strictly implementing acceptance standards, the safety hazards caused by hollowing problems can be effectively avoided to ensure the quality and service life of the house.

[0003] Building hollow detection is an important part of ensuring housing quality. Commonly used methods include tapping, visual inspection and instrument detection. Instrument detection includes ultrasonic detection and infrared thermal imaging. The infrared thermal imaging method identifies hollows by detecting the temperature distribution on the wall surface, but is greatly affected by the temperature of the construction site, resulting in a small temperature difference between the wall and the internal air. In particular, the wall temperature rises during the day, which conflicts with daytime construction, resulting in the judgment accuracy being affected by the detection time and environment, which in turn leads to reduced clarity after identification and unclear distribution, reducing the performance of the monitoring equipment.

[0024] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0025] like Figure 1-6 As shown, the building hollowing infrared detection device comprises: A bottom plate 1, the top of the bottom plate 1 is fixedly connected to the top plate 3 through a bracket 2, a telescopic member 7 is rotatably connected to the bottom of the bracket 2, and the telescopic member 7 is rotatably connected to the heating mechanism, the telescopic member 7 is connected to the bottom of one side of the top plate 3 through an electric push rod 13, a driving mechanism is fixedly installed on the surface of the bottom plate 1, and the driving mechanism is communicated with the inside of the telescopic member 7; The sleeve 17 has two ends fixedly connected to the bottom plate 1 and the top plate 3 respectively, a threaded rod 19 is movably sleeved inside the sleeve 17, a supporting mechanism is fixedly installed on the top of the threaded rod 19, and a transmission mechanism is rotatably connected to the top of the sleeve 17.

[0026] The bottom of the base plate 1 is rotatably connected to the walking wheel 5 and the roller 6 respectively, and a power box 4 is fixedly installed on the top surface of the base plate 1. The power box 4 is located between the four brackets 2, and the side walls of two of the brackets 2 are connected to the telescopic member 7; the telescopic member 7 is composed of a plurality of tube bodies that are mutually socketed, and adjacent tube bodies are sealed and slid with each other. The tube body located in the center is rotatably connected to the heating mechanism, and the top end of the tube body located on the outside is rotatably connected to the electric push rod 13; the heating mechanism is composed of a movable plate 8, and an infrared heat source plate 9 is fixedly installed on the surface of the movable plate 8, and the bottom of the movable plate 8 is fixedly connected to the cross bar 10 through a support rod.

[0027] In this technical solution, the movement of the equipment can be achieved through the walking wheels 5 and the rollers 6, and the wall can be heated by moving it to the position to be tested through the heating mechanism. The different temperature transfer rates between the wall and the air inside the wall are used to determine the thermal imaging pattern, thereby more clearly determining the hollow position.

[0028] A side plate 11 is fixedly connected to one side of the bottom of the base plate 1, and the side wall of the side plate 11 and the surface of the base plate 1 are fixedly connected to the hook 12, and a handrail 29 is fixedly connected to the other side of the top of the base plate 1; the bottom of the top plate 3 is rotatably connected to the inclined electric push rod 13, and two sleeves 17 are provided on one side of the top plate 3, and the two sleeves 17 are symmetrically distributed on both sides of the driving mechanism; the driving mechanism consists of an oil tank 14 and an oil pump 15, the oil tank 14 is fixedly installed on the surface of the base plate 1, the oil pump 15 is fixedly connected to the top of the oil tank 14, and the oil pump 15 is connected to the inside of the two telescopic parts 7 through a hose 16.

[0029] In the present technical solution, after the handrail 29 is used to move the device to one side of the wall, the hydraulic oil pump 15 in the oil tank 14 is sent to the telescopic member 7, and the pressure generated forces the telescopic member 7 to extend, and the electric push rod 13 controls its extension direction, so that it drives the movable plate 8 and the infrared heat source plate 9 to move and adjust the height. At this time, the infrared heat source plate 9 is kept vertical and close to the wall by its own weight. When the use is completed, the cross bar 10 at the bottom of the movable plate 8 is controlled to move to the hook 12 on the bottom plate 1, and the cross bar 10 is hung on the hook 12. The telescopic member 7 continues to shorten, and the electric push rod 13 continues to extend to make the movable plate 8 rotate around the hook 12 to fit the surface of the bottom plate 1 for storage, which is convenient for subsequent use; when performing ground detection, keep the movable plate 8 in a vertical state and move the cross bar 10 to the hook 12 on the side plate 11. When the movable plate 8 is moved forward horizontally, the movable plate 8 rotates around the hook 12 on the side plate 11, thereby driving the infrared heat source plate 9 to approach the ground, thereby facilitating local heating of the ground for identification by the thermal imager 28 on the cross plate 27.

[0030] The support mechanism is composed of a support plate 20 and a cross plate 27. The support plate 20 is fixedly connected to the top of the threaded rod 19, the cross plate 27 is fixedly connected to the top of the power box 4, and the tops of the support plate 20 and the cross plate 27 are fixedly connected to the thermal imager 28; the transmission mechanism is composed of a limit plate 23 and a pulley 24. The limit plate 23 is an L-shaped structure and is fixedly connected to the surface of the top plate 3. A pulley 24 is provided between the limit plate 23 and the top plate 3. The inner ring of the pulley 24 is threadedly sleeved with the surface of the threaded rod 19. The surface of the threaded rod 19 is provided with a convex rib 18 Matching grooves, and the convex rib 18 is fixedly connected to the inner wall of the sleeve 17, a motor 26 is fixedly installed at the bottom of the top plate 3, the output end of the motor 26 is fixedly connected to one of the pulleys 24, and the pulleys 24 are connected by a belt 25; the top of the threaded rod 19 is connected to the support plate 20 through a reinforcing rib, and two guide sleeves 21 are fixedly installed on one side of the support plate 20, and the guide sleeve 21 is composed of two rod bodies that are socketed with each other, the bottom end of the rod body located inside is fixedly connected to the limiting block 22, and the rod body located outside is inserted through the top plate 3.

[0031] In this technical solution, the motor 26 is started and the pulley 24 is driven to rotate at the limit plate 23 through the transmission of the pulley 24 and the belt 25. When the pulley 24 rotates, the thread of the inner ring is adapted to the threaded rod 19, and the groove on the surface of the threaded rod 19 and the rib 18 in the sleeve 17 restrict it to move vertically, thereby making the threaded rod 19 move vertically inside the sleeve 17 and drive the support plate 20 to rise and fall, thereby adjusting the height of the thermal imager 28 to adapt to the height of the heating area.

[0032] Specifically, an infrared thermal imager is used to observe the building to be inspected. Based on the characteristic that the air content at the hollow location is higher than that at the non-hollow location, which leads to differences in heat transfer rate and distribution, the location, shape and size of the hollow in the building can be intuitively observed through infrared thermal imaging, and marked efficiently and accurately.

[0033] Furthermore, an infrared thermal imager is used to collect infrared imaging data at the building structure to be tested, and the data is saved. When collecting data, the area with obvious color inconsistency that is prominent in the infrared imaging field of view of the target can be marked as a possible hollow area one; the collected infrared thermal imaging data is further analyzed and processed, and the relatively hidden hollow area and the normal area are divided using sharpness enhancement algorithm, contrast adjustment algorithm and other schemes, and the hollow area two is marked; the target area is irradiated for a fixed time when the target area is thicker or the heat transfer is slower using infrared heat source plate 9, and after removing the infrared heat source plate 9, the changes in the target area in the infrared field of view are observed, and the area with incoherence or color changes is marked as a hollow area three; the target area is irradiated from the back of the target area when the target area is thinner or the heat transfer is faster using infrared heat source plate 9, and after removing the infrared heat source plate 9, the changes in the target area in the infrared field of view are observed, and the area with incoherence or color changes is marked as a hollow area three; the hollow area one is merged with the hollow area two and the hollow area three, and the final on-site confirmation and repair of the hollow area are carried out.

The protection scope of the present invention is defined by the attached claims.
