[0005] The purpose of this application is to provide a building energy efficiency testing device that has the advantages of strong applicability and solves the problem of not being able to test curved insulation panels.

[0006] The building energy efficiency testing device provided in this application adopts the following technical solution: it includes a base plate, a heating box, and a testing box. The top of the inner wall of the heating box and the testing box are both located on the top of the base plate. The top of the inner wall of the heating box and the bottom of the inner wall of the testing box are both provided with grooves. A lead screw is provided in each of the two sets of grooves through a rotating shaft. A threaded block is threadedly connected to the surface of each of the two sets of lead screws. An adjustment mechanism is provided on the top of each of the two sets of threaded blocks. A heating mechanism and a testing mechanism are respectively provided in each of the two sets of adjustment mechanisms. A second drive motor is provided on one side of each of the heating box and the testing box. The other end of the output shaft of each of the two sets of second drive motors is fixedly connected to the other end of each of the two sets of lead screws through a rotating shaft. By adopting the above technical solution, the heating mechanism and the detection mechanism can be adjusted and moved through the base plate, heating box, detection box and screw drive structure. This allows the device to adapt to the shape characteristics of curved heat insulation panels, breaking through the limitation of traditional devices that are only suitable for planar detection. It can detect curved heat insulation panels and improve the equipment's versatility for heat insulation materials of different shapes.

[0007] Preferably, the adjusting mechanism includes a connecting rod, a spring is provided at the bottom end of the connecting rod, a universal wheel is fixedly connected to the other end of the spring, and the heating mechanism is provided on the surface of the universal wheel.

[0008] By adopting the above technical solution, the adjustment mechanism, through the cooperation of connecting rods, springs and casters, utilizes the elastic buffer of the springs and the multi-angle adaptive capability of the casters. When the casters slide on the surface of the curved heat insulation plate, the gap change between the heating mechanism, the detection mechanism and the curved surface is small, effectively reducing the gap fluctuation caused by the curvature of the curved surface, ensuring the uniformity of heating and detection, and enhancing the equipment's adaptation accuracy to the curved surface.

[0009] Preferably, the heating mechanism has multiple sets of air ducts at the top, a first drive motor at the top of the air ducts, a blower at the other end of the output shaft of the first drive motor, and two sets of connecting frames at the bottom of the heating mechanism, with heating rods inside the two sets of connecting frames.

[0010] By adopting the above technical solution, the heating mechanism, with the help of a fan, a drive motor, a blower and a heating rod, can provide a stable heat source through the heating rod and blow hot air straight onto the surface of the heat insulation board with the help of the blower and the fan, thus heating the curved heat insulation board.

[0011] Preferably, the detection mechanism includes a mounting plate, and a plurality of temperature sensors are disposed on the top of the mounting plate.

[0012] By adopting the above technical solution, the testing agency can simultaneously collect the temperature of the curved heat insulation board by mounting multiple temperature sensors on the mounting plate, reflecting the heat conduction characteristics of the heat insulation board.

[0013] Preferably, the inner walls of both the heating box and the detection box are provided with multiple adaptive clamping structures, and each set of adaptive clamping structures is provided with an adaptive clamping rod. The adaptive clamping rod and the adaptive clamping structure are provided with fluid steel column particles.

[0014] By adopting the above technical solution, the adaptive clamp structure utilizes the fluidity of the fluid steel column particles and the deformation capability of the adaptive clamping rod to automatically adjust the clamping shape according to the shape of the curved heat insulation plate, thereby achieving stable fixation of the curved material, preventing the heat insulation plate from shifting during the testing process, and ensuring the stability of the testing process.

[0015] Preferably, each of the two sets of grooves is provided with a sliding groove, and a slider is slidably connected in the sliding groove, the slider being fixedly connected to one side of the threaded block.

[0016] By adopting the above technical solution, the groove in the groove cooperates with the slider to limit the movement direction of the threaded block, so as to avoid the threaded block from deviating or jamming when the screw is driven, and to ensure that the heating mechanism and the detection mechanism move smoothly.

[0017] Preferably, the top of the heating box is provided with a heat-insulating main board, and the top of the heat-insulating main board is provided with two sets of handles, and the surface of both sets of handles is provided with anti-slip sleeves.

[0018] By adopting the above technical solutions, the heat-insulating main board on the top of the heating box can reduce heat diffusion to the outside and reduce energy loss. The combination of the handle and the anti-slip sleeve facilitates equipment handling, enhances grip stability during operation, and improves the practicality and operational safety of the equipment.

[0019] Preferably, soft pads are fixedly connected to the bottom of the base plate near the four corners, and observation windows are opened on the surface of both the heating box and the detection box.

[0020] By adopting the above technical solution, the soft pad at the bottom of the base plate can buffer the vibration when the equipment is placed, while increasing the friction with the contact surface to prevent the equipment from sliding, and the observation window facilitates real-time observation of the internal detection status.

[0021] Preferably, the top of the detection box has a slot, the heating box is snapped into the slot, and a sealing strip is provided in the slot.

[0022] By adopting the above technical solution, the slot of the detection box and the sealing strip work together to enhance the sealing of the connection between the heating box and the detection box, reduce heat leakage during the heating process, avoid the impact of temperature fluctuations on the accuracy of the detection data, and ensure the stability of the detection environment.

[0023] Preferably, elastic retaining rings are fixedly connected to both sides of the detection box, and retaining plates are fixedly connected to both sides of the heating box, with the two sets of retaining plates respectively engaging within the two sets of elastic retaining rings.

[0024] By adopting the above technical solution, the snap-fit ​​structure between the elastic retaining ring and the retaining plate not only ensures the firmness of the connection between the heating box and the detection box, but also facilitates quick disassembly and assembly, simplifying the equipment assembly and maintenance process and improving the efficiency of equipment use.

[0025] In summary, this application includes at least one of the following beneficial technical effects: This building energy efficiency testing device, through a base plate, heating box, testing box, and screw drive structure, enables adjustable movement of the heating and testing mechanisms. It can adapt to the shape characteristics of curved insulation panels, overcoming the limitations of traditional devices that are only suitable for flat surface testing. This allows for testing of curved insulation panels, improving the device's versatility for insulation materials of different shapes. The mechanism, through the cooperation of connecting rods, springs, and casters, utilizes the elastic buffering of the springs and the multi-angle adaptive capability of the casters. When the casters slide on the surface of the curved insulation panel, the gap change between the heating and testing mechanisms and the curved surface is small, effectively reducing gap fluctuations caused by the curvature of the curved surface, ensuring uniform heating and testing, and enhancing the device's adaptation accuracy to curved surfaces.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0029] Example 1: A building energy efficiency testing device, referring to Figure 1 , Figure 3 and Figure 4 The device includes a base plate 1, a heating box 3, and a detection box 2. The top of the inner wall of the heating box 3 and the detection box 2 are both located on the top of the base plate 1. The top of the inner wall of the heating box 3 and the bottom of the inner wall of the detection box 2 are both provided with grooves 8. Each of the two sets of grooves 8 is equipped with a lead screw 9 through a rotating shaft. The surfaces of the two sets of lead screws 9 are threaded with threaded blocks 10. The top of each set of threaded blocks 10 is provided with an adjustment mechanism 5. The two sets of adjustment mechanisms 5 are respectively provided with a heating mechanism 7 and a detection mechanism 6. Each of the heating box 3 and the detection box 2 is provided with a second drive motor 19 on one side. The other end of the output shaft of the two sets of second drive motors 19 is fixedly connected to the other end of the two sets of lead screws 9 through a rotating shaft. Through the drive structure of the base plate 1, the heating box 3, the detection box 2, and the lead screw 9, the adjustable movement of the heating mechanism 7 and the detection mechanism 6 is realized, which can adapt to the shape characteristics of curved heat insulation panels. It breaks through the limitation of traditional devices that can only be used for flat surface detection, and can detect curved heat insulation panels, thus improving the versatility of the equipment for heat insulation materials of different shapes.

[0030] Example 2: A building energy efficiency testing device, referring to... Figure 3 , Figure 4 and Figure 5The adjusting mechanism 5 includes a connecting rod 501, with a spring 502 at the bottom end of the connecting rod 501. A caster wheel 503 is fixedly connected to the other end of the spring 502. A heating mechanism 7 is disposed on the surface of the caster wheel 503. Multiple sets of air ducts 703 are disposed on the top of the heating mechanism 7. A first drive motor 701 is disposed on the top of each air duct 703. A blower fan 702 is disposed at the other end of the output shaft of the first drive motor 701. Two sets of connecting brackets 704 are disposed at the bottom of the heating mechanism 7. The inner... A heating rod 705 is provided. The detection mechanism 6 includes a mounting plate 601. Multiple temperature sensors 602 are installed on the top of the mounting plate 601. Multiple adaptive clamping structures 4 are provided on the inner walls of both the heating box 3 and the detection box 2. Each set of adaptive clamping structures 4 is equipped with an adaptive clamping rod 401. Flowable steel column particles are installed inside the adaptive clamping rods 401 and the adaptive clamping structures 4. The adjustment mechanism 5 utilizes the elasticity of the spring 502 to buffer the load through the cooperation of the connecting rod 501, the spring 502, and the universal wheel 503. With the multi-angle adaptive capability of the caster wheel 503, the gap change between the heating mechanism 7, the detection mechanism 6 and the curved surface is small when the caster wheel 503 slides on the curved heat insulation plate surface. This effectively reduces gap fluctuations caused by the curvature of the curved surface, ensuring heating and detection uniformity and enhancing the equipment's adaptation accuracy to the curved surface. The heating mechanism 7, with the help of the air duct 703, drive motor, blower 702 and heating rod 705, can provide a stable heat source through the heating rod 705 and dissipate heat through the blower 702 and air duct 703. The air blowing directly onto the surface of the curved insulation board can heat the curved insulation board. The testing mechanism 6, equipped with multiple temperature sensors 602 on the mounting plate 601, can simultaneously collect the temperature of the curved insulation board, reflecting its thermal conductivity characteristics. The adaptive clamping structure 4 utilizes the fluidity of the flowing steel column particles and the deformation capability of the adaptive clamping rod 401 to automatically adjust the clamping shape according to the shape of the curved insulation board, achieving stable fixation of the curved material, preventing the insulation board from shifting during the testing process, and ensuring the stability of the testing process.

[0031] Example 3: A building energy efficiency testing device, referring to Figure 1 , Figure 6Both sets of grooves 8 have sliding grooves 12, and sliders 11 are slidably connected in the sliding grooves 12. The sliders 11 are fixedly connected to one side of the threaded block 10. The top of the heating box 3 is provided with a heat-insulating main plate 16, and the top of the heat-insulating main plate 16 is provided with two sets of handles 18. The surfaces of the two sets of handles 18 are provided with anti-slip sleeves 17. Soft pads 15 are fixedly connected to the bottom of the base plate 1 near the four corners. The surfaces of the heating box 3 and the detection box 2 are provided with observation windows 22. The top of the detection box 2 is provided with a slot 13, and the heating box 3 is snapped into the slot 13. A sealing strip 14 is provided in the slot 13. Elastic retaining rings 21 are fixedly connected to both sides of the detection box 2, and retaining plates 20 are fixedly connected to both sides of the heating box 3. The two sets of retaining plates 20 are respectively snapped into the two sets of elastic retaining rings 21. The sliding grooves 12 in the grooves 8 cooperate with the sliders 11 to limit the movement direction of the threaded block 10, so as to prevent the threaded block 10 from deviating or jamming when driven by the screw 9. The heating mechanism 7 and the detection mechanism 6 move smoothly. The heat-insulating main plate 16 on the top of the heating box 3 reduces heat diffusion to the outside and lowers energy loss. The combination of the handle 18 and the anti-slip sleeve 17 facilitates equipment handling, enhances grip stability during operation, and improves the practicality and operational safety of the equipment. The soft pad 15 at the bottom of the base plate 1 can cushion vibrations when the equipment is placed, while increasing friction with the contact surface to prevent the equipment from sliding. The observation window 22 facilitates real-time observation of the internal detection status. The slot 13 of the detection box 2 cooperates with the sealing strip 14 to enhance the sealing at the joint between the heating box 3 and the detection box 2, reduce heat leakage during the heating process, avoid the impact of temperature fluctuations on the accuracy of the detection data, and ensure the stability of the detection environment. The snap-fit ​​structure of the elastic retaining ring 21 and the retaining plate 20 not only ensures the firmness of the connection between the heating box 3 and the detection box 2, but also facilitates quick disassembly and assembly, simplifying the equipment assembly and maintenance process and improving the efficiency of equipment use.

[0032] The implementation principle of this application embodiment is as follows: When using the building energy-saving testing device, first place the device on a stable workbench. The soft pad 15 at the bottom of the base plate 1 can enhance stability and prevent slippage. Open the heating box 3 and the testing box 2. Then, place the curved heat insulation plate to be tested between the heating box 3 and the testing box 2. The adaptive clamping structure 4 on the inner wall of the heating box 3 and the testing box 2 will automatically adjust the clamping shape through the fluidity of the fluid steel column particles and the deformation of the adaptive clamping rod 401, stabilize and fix the curved heat insulation plate, and prevent displacement during the testing process. Then, the elastic retaining rings 21 on both sides of the testing box 2 cooperate with the retaining plate 20 of the heating box 3 to initially connect the two, ensuring that the heating box 3 is clamped in the retaining groove 13 at the top of the testing box 2. The sealing strip 14 in the retaining groove 13 can enhance the sealing performance and reduce heat leakage. After starting the device, the second drive motor 19 starts to work, driving the lead screw 9 in the groove 8 to rotate. The threaded block 10 moves on the surface of the lead screw 9, and at the same time, the slider 11 slides in the slide groove 12 to ensure that the threaded block 10 moves smoothly. The system is stable, which in turn drives the adjustment mechanism 5 and the heating mechanism 7 and detection mechanism 6 above it to move synchronously. The universal wheel 503 in the adjustment mechanism 5 slides on the surface of the curved heat insulation plate. The elastic buffer of the spring 502 and the multi-angle adaptive capability of the universal wheel 503 ensure that the heating mechanism 7 and detection mechanism 6 always maintain a small gap fluctuation with the curved surface, ensuring a tight fit. When the heating mechanism 7 is started, the heating rod 705 in the connecting frame 704 generates heat. The first drive motor 701 drives the fan 702 to rotate, and the air duct 703 blows the heat evenly onto the surface of the curved heat insulation plate to achieve stable heating. At the same time, multiple temperature sensors 602 on the mounting plate 601 of the detection mechanism 6 synchronously collect temperature data of different areas of the curved surface, reflecting the heat conduction characteristics of the heat insulation plate. After the test is completed, the equipment is turned off, the elastic retaining ring 21 is released from the retaining plate 20, the curved heat insulation plate is taken out, and the test is completed. Throughout the process, the handle 18 and the anti-slip sleeve 17 facilitate the handling of the equipment, improve the convenience of operation, and ensure efficient and accurate testing of the curved heat insulation plate.
