[0057] Embodiment 1:

[0058] As shown in the drawings, the present embodiment provides a building external wallboard insulation performance detection device, comprising: Figures 1-3 a bottom plate 1;

[0059] a support plate 2 arranged around the top of the bottom plate 1;

[0060] a top plate 3 arranged between the four support plates 2;

[0061] an outer shell 4 arranged on the top plate 3, the outer shell 4 covering the top plate 3 and other components inside the top plate 3;

[0062] a protective door 41 arranged on the front side of the outer shell 4 through a movable connection assembly, used to open or close the outer shell 4 to realize the taking and placing of the wallboard inside the outer shell 4;

[0063] a heating unit 8 arranged on the top plate 3, used to heat the wallboard;

[0064] a detection assembly 9 arranged inside the outer shell 4, used to detect the insulation performance of the wallboard;

[0065] a clamping plate assembly 5 arranged on the bottom plate 1, used to clamp the wallboard on the heating unit 8;

[0066] The clamping plate assembly 5 comprises:

[0067] a guide rod 51 arranged between two support plates 2 on the same side;

[0068] a sliding sleeve 52 slidingly arranged at both ends of the guide rod 51;

[0069] a connecting plate 53 arranged between the top of the two sliding sleeves 52 in the transverse direction;

[0070]

[0071] ​Supporting rods 54 are arranged on the left and right sides of the connecting plate 53.

[0072] Positioning plates 55 are arranged between the two supporting rods 54 on the same side.

[0073] A power unit 56 is used to provide power to drive the two connecting plates 53 to move closer to or away from each other, so as to realize the clamping or loosening of the positioning plates 55 on the wallboard.

[0074] In the technical solution, the bottom plate 1 serves as the basis of the entire device, providing a stable support platform for other components, and ensuring that the device does not shift or sway during operation. The supporting plate 2 is arranged around the top of the bottom plate 1, and together with the bottom plate 1 forms a frame structure of the device, bearing the weight of the top plate 3 and other components, and ensuring the overall stability of the device. The top plate 3 provides a mounting position for the heating unit 8, the detection assembly 9, etc. The shell 4 covers the top plate 3 and other components inside the top plate 3, protecting the internal components from external environmental interference, and also helping to maintain the stability of the detection environment. The protective door 41 is arranged on the front side of the shell 4 through a movable connection assembly, facilitating the opening or closing of the shell 4 by the operator. When it is necessary to put in the wallboard to be detected or take out the wallboard that has been detected, the protective door 41 can be opened to facilitate the operation of the space inside the shell 4. The heating unit 8 is arranged on the top plate 3, and its main function is to simulate the heat transfer condition of the outer wall of a building in actual use, and to create necessary temperature conditions for detecting the thermal insulation performance of the wallboard by heating the wallboard. The detection assembly 9 is arranged inside the shell 4, and can accurately measure and analyze the temperature change and heat transfer of the wallboard during the heating process. Through these data, the thermal insulation performance of the wallboard, such as the heat transfer coefficient, thermal resistance, and other key indicators, can be accurately evaluated. The clamping plate assembly 5 is used to clamp the wallboard on the heating unit 8, ensuring that the wallboard remains stable during the detection process and does not sway or shift to affect the accuracy of the detection results. Specifically, the guide rod 51 is arranged between the two supporting plates 2 on the same side, providing a guide function for the sliding of the sliding sleeve 52, and ensuring the straightness of the sliding sleeve 52 during movement. The connecting plate 53 connects the top of the two sliding sleeves 52 in the transverse direction, and transmits the movement of the sliding sleeves 52 to the supporting rods 54 and the positioning plates 55. The supporting rods 54 are arranged on the left and right sides of the connecting plate 53, and are used to support the positioning plates 55 and convert the movement of the connecting plate 53 into the movement of the positioning plates 55 in the vertical direction. The positioning plates 55 are arranged between the two supporting rods 54 on the same side, and directly contact the wallboard. By moving the two positioning plates 55 closer to or away from each other, the wallboard can be clamped or loosened. The power unit 56 provides power for the movement of the two connecting plates 53 closer to or away from each other. Through a transmission mechanism (such as a screw nut mechanism or a chain transmission mechanism), the power is transmitted to the connecting plate 53, realizing the precise clamping and loosening of the wallboard by the positioning plates 55.

[0075] Workflow: Open the protective door 41, place the building exterior wall panel to be detected on the heating unit 8, ensure that the position of the wall panel is accurate and in full contact with the heating unit 8. Start the power part 56 of the clamping plate assembly 5, drive the two connecting plates 53 on both sides to approach each other through the power part 56, and drive the positioning plate 55 to gradually move towards the wall panel. When the positioning plate 55 is in close contact with the wall panel, continue to apply a certain clamping force to ensure that the wall panel does not shift during the detection process; then close the protective door 41 to ensure that a relatively closed detection environment is formed inside the shell 4. Then start the heating unit 8 and heat the wall panel according to the preset heating program. During the heating process, the detection assembly 9 monitors the temperature changes on the surface and inside the wall panel, as well as the heat transfer situation. For example, the temperature sensor 93 can measure the temperature at different positions of the wall panel, and the heat meter 94 can measure the heat flow through the wall panel. The detection assembly 9 transmits the measured data to the data processing system (which can be integrated inside the device or connected to an external computer). The data processing system analyzes and calculates the data according to the preset algorithm to obtain the thermal performance parameters of the wall panel, such as the heat transfer coefficient and thermal resistance. After the detection is completed, the heating unit 8 stops heating, and after the wall panel cools down to a safe temperature, the protective door 41 is opened, the power part 56 of the clamping plate assembly 5 is started, and the two connecting plates 53 on both sides are driven to move away from each other, so that the positioning plate 55 releases the wall panel. Take out the detected wall panel, clean the heating unit 8 and the debris inside the device, and prepare for the next detection. Organize and save the data obtained from this detection to generate a detection report, which provides a basis for performance evaluation and improvement of building exterior wall panels. This way, the thermal performance of different types of exterior wall panels can be detected, which can help building material production enterprises optimize product design and provide reliable material selection basis for building construction parties, thereby improving the overall energy-saving effect and living quality of buildings.

[0076] As shown in Figure 2 and Figure 3 In this embodiment, the optimized power part 56 includes:

[0077] The rack 561 is arranged on the front and rear sides of the top plate 3.

[0078] The motor 562 is arranged on the rack 561.

[0079] The synchronous wheel 563 is arranged on the output shaft of the motor 562.

[0080] The synchronous belt 564 is sleeved between the two synchronous wheels 563.

[0081] The action plate 565 has two, which are arranged on the right end of the front side and the left end of the rear side of the synchronous belt 564, and the action plate 565 is connected with the connecting plate 53.

[0082] In the technical solution, when the building external wall panel to be detected is placed on the heating unit 8, the motor 562 is started, the output shaft of the motor 562 drives the synchronous wheel 563 installed thereon to rotate, the rotation of the synchronous wheel 563 drives the synchronous belt 564 to start moving, since the synchronous belt 564 is closely engaged with the synchronous wheels 563 on both sides, the synchronous wheel 563 on the other side also rotates synchronously, the movement of the synchronous belt 564 makes the action plates 565 arranged at the right front side and the left rear side of the synchronous belt 564 start moving inward, the movement of the action plates 565 pushes the connecting plates 53 connected thereto to slide on the guide rods 51, the connecting plates 53 drive the supporting rods 54 and the positioning plates 55 to move close to the wall panel. As the positioning plates 55 gradually contact the wall panel, the positioning plates 55 exert a certain clamping force on the wall panel. When the preset clamping force is reached, the motor 562 stops running, at this time, the wall panel is stably clamped on the heating unit 8, ready for the heat preservation performance detection. When the heat preservation performance detection is completed, the heating unit 8 stops heating, at this time, the motor 562 is started, the motor 562 runs in the reverse direction according to the preset reverse direction, the output shaft drives the synchronous wheel 563 to rotate reversely, the reverse rotation of the synchronous wheel 563 makes the synchronous belt 564 move reversely, the action plates 565 move outward, driving the connecting plates 53, the supporting rods 54 and the positioning plates 55 to move away from the wall panel, when the positioning plates 55 completely release the wall panel, the motor 562 stops running. The operator can open the protective door 41 to take out the detected wall panel, completing the entire detection process. The power unit 56 provides stable and controllable power for the clamping plate assembly 5 to realize precise clamping and releasing operation of the building external wall panel. During the building external wall panel heat preservation performance detection process, the stable clamping force can ensure that the wall panel is fixed in position during detection, avoiding the interference of shaking or displacement with the accuracy of the detection result.

[0083] As shown in the drawings, Figure 2 In the embodiment, the top plate 3 is provided with a sliding groove 6 for the supporting rod 54 to slide.

[0084] In the technical solution, the sliding groove 6 provides a specific sliding track for the supporting rod 54. When the power unit 56 drives the connecting plate 53 to move, the supporting rod 54 connected thereto slides in the sliding groove 6 along the preset direction, which can effectively limit the freedom of the supporting rod 54 in the horizontal direction, so that it can only move in the straight line direction defined by the sliding groove 6. This ensures that the positioning plate 55 always maintains a posture perpendicular to the surface of the wall panel during the process of moving close to or away from the wall panel, thereby uniformly applying the clamping force and preventing the wall panel from tilting due to stress and affecting the detection accuracy.

[0085] The clamping assembly further comprises a non-slip pad 7 arranged on the surface of the positioning plate 55 in contact with the wall panel.

[0086] In the technical solution, the anti-slip pad 7 is arranged on the surface of the positioning plate 55 in contact with the wallboard, and the core purpose is to enhance the friction between the positioning plate 55 and the wallboard, prevent the wallboard from sliding due to various external forces (such as vibration, slight displacement generated by the operation of the detection equipment, etc.) during the detection process, and ensure that the wallboard always maintains a stable position in the detection device, thereby improving the accuracy and reliability of the thermal insulation performance detection result. At the same time, the arrangement of the anti-slip pad 7 can also protect the surface of the wallboard to a certain extent, avoiding scratching or damage caused by the direct contact of the positioning plate 55 with the wallboard. The anti-slip pad 7 has special surface texture or material properties, which can greatly increase the friction with the surface of the wallboard. When the positioning plate 55 exerts a clamping force on the wallboard, the anti-slip pad 7 tightly adheres to the wallboard, effectively preventing the wallboard from moving in the horizontal or vertical direction by utilizing its high friction. Even if there is a slight shaking during the operation of the detection device or due to other operations, the anti-slip pad 7 can ensure that the wallboard is stably positioned for detection, so that the detection process is not disturbed by the displacement of the wallboard, and the authenticity and effectiveness of the detection data are guaranteed. The anti-slip pad 7 usually has a certain elasticity and softness, and plays a buffering role between the positioning plate 55 and the wallboard. When the positioning plate 55 clamps the wallboard, the anti-slip pad 7 can uniformly distribute the clamping force, avoiding local stress concentration on the surface of the wallboard caused by the positioning plate 55, thereby preventing the surface of the wallboard from being scratched, worn or deformed. This is particularly important for some external wallboards with relatively fragile surfaces or high requirements for appearance quality, which can not only ensure smooth detection, but also protect the integrity of the wallboard, facilitating subsequent use or evaluation.

[0087] Embodiment 2:

[0088] The embodiment provides a building external wallboard thermal insulation performance detection device, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0089] As shown in Figure 2 and Figure 4 , in this embodiment, the optimized heating unit 8 includes:

[0090] The shell 81 is arranged on the top plate 3;

[0091] The heating chamber 82 is opened in the shell 81, and the heating chamber 82 is made of stainless steel;

[0092] The heating element 83 is arranged inside the heating chamber 82;

[0093] The air outlet shell 84 is arranged at the top of the shell 81, and the air outlet shell 84 is in communication with the heating chamber 82, for transmitting heat to the wallboard;

[0094] The support block 85 is arranged on the left and right sides of the top plate 3, and the support block 85 has two, which are respectively located on the two sides of the shell 81, and the support block 85 is used for supporting the wallboard.

[0095] In this technical solution, when the wallboard needs to be tested for thermal insulation performance, first place the wallboard on the support block 85 so that it is above the air outlet shell 84, then start the heating unit 8, and the heating element 83 starts to work, converting electrical energy into heat energy, gradually increasing the temperature inside the heating chamber 82. As the temperature rises, heat is evenly conducted through the stainless steel walls of the heating chamber 82 to the entire chamber interior, and is transmitted to the wallboard through the air outlet shell 84, allowing it to reach the preset detection temperature and remain for a period of time to ensure that the temperature distribution inside the wallboard reaches a stable state. In this process, the detection assembly 9 simultaneously monitors and records the temperature changes and other parameters of the wallboard, providing data support for subsequent thermal insulation performance analysis. During the detection process, if the heating of the wallboard is not ideal, such as localized high or low temperatures, or the temperature rise rate of the wallboard does not meet expectations, the operator can adjust the heating unit 8. For example, if a part of the wallboard is found to be too hot, the power of the corresponding heating element 83 in that area can be reduced, or the air flow direction of the air outlet shell 84 can be adjusted to make the heat distribution more uniform. When the thermal insulation performance detection is complete, stop the heating unit 8 and the heating element 83 stops heating, thus heating the wallboard to accurately detect its thermal insulation and heat insulation capacity. Specifically, the heating element 83 generates heat, which is effectively transferred to the wallboard through a specific structural design, while ensuring the uniformity and stability of the heating process, providing a basis for the detection assembly 9 to obtain accurate thermal insulation performance data, and assisting in evaluating the actual thermal insulation effect of the external wallboard in different building scenarios.

[0096] Example 3:

[0097] This embodiment provides a building external wallboard thermal insulation performance detection device, in addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features.

[0098] As shown in Figure 2 and Figure 5 In this embodiment, the optimized detection assembly 9 includes;

[0099] The electric push rod 91 is arranged on the housing 4;

[0100] The push plate 92 is arranged on the piston rod of the electric push rod 91;

[0101] The temperature sensor 93 is arranged at the bottom of the push plate 92 and above the support block 85, used to monitor the temperature changes of the wall in real time and feed back the data to the data processing unit 95;

[0102] The heat meter 94 is used to measure the heat flow through the wallboard;

[0103] The data processing unit 95 compares the collected temperature values with the preset value information according to the feedback temperature information of the temperature sensor 93 and the heat meter 94, so as to detect the heat preservation performance of the wallboard.

[0104] The display module 96 is electrically connected with the communication module and is used for displaying the detected data.

[0105] In the technical solution, when the heating unit 8 heats the wallboard to a preset time or temperature, the electric push rod 91 starts to work, the piston rod pushes the push plate 92 to slowly move downward until the temperature sensor 93 is close to the surface of the wallboard. The temperature sensor 93 monitors the temperature change of the wall in real time and feeds back the measured data to the data processing unit 95 in real time. At the same time, the heat meter 94 continuously measures the heat flow through the wallboard and synchronously transmits the data to the data processing unit 95. The data processing unit 95 continuously receives these real-time data and preliminarily sorts and stores the data according to the preset algorithm. The data processing unit 95 compares and analyzes the collected temperature values with the preset value information. According to the temperature change curve and the heat flow data, the heat transfer coefficient, the thermal resistance and other key heat preservation performance indexes of the wallboard are calculated. For example, by analyzing the rising or falling amplitude of the temperature within a certain time, combining the heat flow measured by the heat meter 94, and using the heat conduction formula to calculate the heat transfer coefficient, the heat preservation and insulation capacity of the wallboard is evaluated. The data processing unit 95 transmits the calculated heat preservation performance data and the original measurement data of the temperature sensor 93 and the heat meter 94 to the display module 96. The display module 96 presents the detected data in the form of intuitive charts, numbers and the like, such as real-time temperature curve, heat flow value, heat preservation performance index and the like. The operator can clearly view the detection results through the display module 96 to judge whether the heat preservation performance of the external wallboard meets the standard.

[0106] When the detection is completed, the electric push rod 91 retracts the push plate 92 to the initial position. The data processing unit 95 sorts and stores the data of this detection, generates a detection report containing detailed information such as detection time, detection parameters, and insulation performance evaluation results. The operator can evaluate and analyze the performance of the external wall panel according to the detection report. Then, check and maintain each part of the detection assembly 9, such as checking whether the temperature sensor 93 is damaged and whether the measurement accuracy of the calorimeter 94 changes, etc., to prepare for the next detection. In this way, the temperature change and heat transfer data of the building external wall panel during the heating process are obtained comprehensively and accurately, and the insulation performance of the external wall panel is accurately evaluated through scientific data processing and analysis. The temperature sensor 93 monitors the temperature change of the wall in real time, and the calorimeter 94 measures the heat flow through the wall panel. The data of the two are fed back to the data processing unit 95, and the quantitative results of the insulation performance of the external wall panel are obtained by comparing with the preset value. The display module 96 visually presents these key data to provide clear detection information for the operator, helping them to judge whether the external wall panel meets the insulation performance standard, and providing a strong basis for quality evaluation and improvement of building external wall panels.

[0107] Embodiment 4:

[0108] The embodiment provides a building external wall panel insulation performance detection device, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0109] As shown in Figure 1 In this embodiment, the optimized protective door 41 is provided with an observation window 10.

[0110] In this technical solution, the observation window 10 is arranged on the protective door 41, the main purpose of which is to provide an operator with a direct way to observe the internal situation of the detection device. During the detection of the insulation performance of the building external wall panel, the operator needs to know the state of the wall panel, the working condition of the heating unit 8, and the running condition of the detection assembly 9, etc. in real time. The existence of the observation window 10 enables the operator to directly observe the internal situation without affecting the stability of the detection environment, without the need to frequently open the protective door 41. This helps to timely discover possible abnormalities, such as whether the wall panel has been displaced, whether the heating unit 8 is heating normally, whether the detection assembly 9 is working normally, etc., thereby ensuring the smooth progress of the detection work, improving the detection efficiency and accuracy, and also reducing energy waste and safety risks caused by frequent opening of the door.
