Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation performance detection, in particular to a thermal insulation performance detection device for construction engineering. Background Art

[0002] Construction engineering refers to the construction and installation of buildings and their ancillary facilities, including planning, investigation, design, construction and other technical work. Usually, the thermal insulation performance of the wall is tested in construction engineering. Traditional construction engineering thermal insulation performance testing uses a heating fan and an infrared thermal imager to heat the two sides of the wall with a fan and then use an infrared thermal imager to observe and test. The test requires multiple people to operate, which is inconvenient to use.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN216920448U proposes a thermal insulation performance detection device for construction engineering. The device presses the second card block down to the inside of the groove, and the two springs are in a compressed state, and then the second card block is located inside the second through-hole and moves downward. At this time, the second base is pulled so that the second card block is limited by the limit block. The second card block is trapezoidal in shape and the limit block is triangular in shape, thereby limiting the second card block. When the second base is pulled, the second card block is limited by the limit block and gradually moves downward, so that the second card block is pulled out through the first through-hole, thereby separating the first base and the second base. The device is self-fixed, easy to adjust, and more convenient to use.

[0004] However, although the above-mentioned thermal insulation performance detection device for construction projects can simultaneously hold the first card block and the second card block in the first perforation and the second perforation respectively to realize the positioning of the first base and the second base, and then adjust the height of the infrared thermal imager and the fan, thereby improving the convenience of detecting the thermal insulation performance of the wall, the thermal insulation performance detection device for construction projects needs to fix the first base and the second base and place the fan and the infrared thermal imager on both sides of the wall respectively to realize the detection of the thermal insulation performance of the wall. Since the distance between the first base and the second base is fixed, the detection device cannot accurately detect walls of different thicknesses, thereby causing the problem of reduced applicability of the device. Therefore, the utility model provides a thermal insulation performance detection device for construction projects to meet the needs. Utility Model Content

[0034] like Figures 1 to 6 As shown, an embodiment of the utility model provides a thermal insulation performance detection device for construction engineering, including a fixed block 1, two groups of moving components 3 are relatively movable on both sides of the fixed block 1, and the two groups of moving components 3 are respectively connected to a fan 10 and an infrared thermal imager 12 through two groups of lifting mechanisms 7. A universal wheel is provided at the bottom of the moving component 3, and a driving component 4 for driving the two groups of moving components 3 to move is provided in the fixed block 1.

The driving component 4 includes a rotating shaft 44, which is rotatably arranged in the fixed block 1, and the rotating shaft 44 is driven by a motor 41. A gear 42 and two racks 43 are sleeved on the rotating shaft 44, which are symmetrically slidably arranged in the fixed block 1 along the gear 42, and the two racks 43 are meshed with the gear 42. A slide groove 45 for the rack 43 to slide is provided in the fixed block 1, and the two racks 43 are respectively connected to the two groups of moving components 3.

[0035] Specifically, according to the thickness of the wall, the control mechanism 5 is used to drive the motor 41 to drive the rotating shaft 44 to rotate, and the rotation drives the gear 42 to rotate, and the gear 42 drives the two racks 43 to slide relatively along the slide groove 45, so that the two groups of moving components 3 are relatively moved away from each other through the universal wheel. When the two groups of moving components 3 are the same thickness as the wall, the two groups of moving mechanisms can be pushed to move to both sides of the wall, and then the thermal insulation performance of the wall is tested by the fan 10 and the infrared thermal imager 12. The overall device has a simple structure and can be adjusted according to the thickness of the wall, thereby ensuring the accuracy of the test results, improving the application range of the device, and solving the problem that the existing thermal insulation performance testing device cannot accurately detect walls of different thicknesses due to the fixed distance between the first base and the second base, thereby reducing the applicability of the device.

[0036] It should be noted that the infrared thermal imager 12 and the fan 10 are signal-connected to the control mechanism 5, and the line connection between them is a prior art and will not be described here. Furthermore, the motor 41 can be a three-phase motor 41, a reduction motor 41, etc.

[0037] like Figure 3 and Figure 5 As shown, in this embodiment, two support rods 14 are relatively hinged at the bottom of the fixed block 1, and a limit plate 16 for limiting the two support rods 14 is fixedly connected to the fixed block 1, and a magnet 15 attracted to the support rod 14 is fixedly connected to the fixed block 1 between the two support rods 14. The magnet 15 and the limit plate 16 are relatively arranged along the support rod 14. The support rod 14 is made of iron. Specifically, when it is necessary to move the two groups of movable components 3, the two support rods 14 are adjusted to support the ground, and the limit plate 16 is used for limiting, so that the fixed block 1 can be more stable, which is convenient for the driving component 4 to move the two groups of movable components 3. At the same time, the magnet 15 is used to facilitate the storage of the support rod 14; it should be noted that when the support rod 14 conflicts with the limit plate 16, the two groups of support rods 14 are in an outwardly expanded state.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, the two sets of lifting mechanisms 7 are respectively fixedly connected with support plate mechanisms 8 for supporting the fan 10 and the infrared thermal imager 12, the support plate mechanism 8 is fixedly connected with a distance sensor 9, the moving assembly 3 is fixedly connected with a vertical plate 2, the vertical plate 2 is fixedly connected with a sensing mechanism 13 facing the distance sensor 9, the sensing mechanism 13 and the distance sensor 9 are connected with the control mechanism 5 by signal, the moving assembly 3 includes a moving plate 31 and a telescopic plate 32, the moving plate 31 is movably connected to the fixed block 1 through a rack 43, the telescopic plate 32 is movably arranged in the moving plate 31, and the moving plate 31 is provided with a second movable groove 17 for the telescopic plate 32 to move. Specifically, when the telescopic plate 32 moves along the moving plate 31, When moving, through the cooperation of the distance sensor 9 and the sensing mechanism 13, it is convenient for the user to control the moving distance of the telescopic plates 32 of the two groups of moving components 3, so that the infrared thermal imager 12 and the fan 10 can be symmetrically arranged along the wall, thereby improving the accuracy of the detection of the thermal insulation performance of the wall; it should be noted that the sensing mechanism 13 will forward the signal sent by the distance sensor 9 to the control mechanism 5, and display it through the display screen on the control mechanism 5, so that the user can monitor the distance between the two groups of support plate mechanisms 8 in real time. The signal connection between the sensing mechanism 13 and the distance sensor 9 is a prior art and will not be described here. At the same time, the support plate mechanism 8 is suitable for supporting the fan 10 and the infrared thermal imager 12.

[0039] like Figure 3 and Figure 6As shown, in the present embodiment, the lifting mechanism 7 includes a fixing rod 74, which is fixedly arranged on the telescopic plate 32, a lifting rod 71, which is movably arranged inside the fixing rod 74, and a first movable groove 11 for the lifting rod 71 to move is provided in the fixing rod 74, and a positioning pin 72 is used to limit the lifting rod 71 and the fixing rod 74. The lifting rod 71 and the fixing rod 74 are penetrated by positioning holes 73 for the positioning pin 72 to position. Specifically, the position of the lifting rod 71 on the fixing rod 74 is controlled, and then positioned by the positioning pin 72, so as to adjust the height of the fan 10 and the infrared thermal imager 12, so as to improve the application range of the device.

[0040] Working principle:

[0041] First, the device is moved to the wall, and then the device is connected to an external power supply. According to the thickness of the wall, the motor 41 drives the rotating shaft 44 to rotate through the control mechanism 5, and the rotation drives the gear 42 to rotate, and the gear 42 drives the two racks 43 to slide relatively along the slide groove 45, so that the two groups of moving components 3 are relatively moved away from each other through the universal wheel. When the thickness of the two groups of moving components 3 is the same as that of the wall, the two groups of moving mechanisms can be pushed to move to both sides of the wall, and the position of the telescopic plate 32 can be adjusted. At the same time, the position of the lifting rod 71 on the fixed rod 74 is controlled, and then the positioning is performed by the positioning pin 72. At this time, the thermal insulation performance of the wall is tested by the fan 10 and the infrared thermal imager 12. The overall device has a simple structure and can be adjusted according to the thickness of the wall, thereby ensuring the accuracy of the test results, improving the scope of application of the device, and solving the problem that the existing thermal insulation performance testing device cannot accurately detect walls of different thicknesses due to the fixed distance between the first base and the second base, thereby reducing the applicability of the device.
