Description

Technical Field

[0001] The present invention relates to the technical field of heat transfer testing for integrated thermal insulation and decoration boards, and specifically to an external thermal insulation heat transfer testing device for integrated thermal insulation and decoration boards. Background Art

[0002] As an important building material, the thermal insulation and heat transfer performance of the integrated thermal insulation and decoration board is one of the key indicators for evaluating its quality. The thermal insulation and heat transfer test aims to evaluate the thermal insulation performance of the integrated thermal insulation and decoration board, that is, its ability to prevent heat transfer. Through testing, the heat transfer coefficient of the board can be understood, so as to judge whether it meets the requirements of building design and relevant standard regulations.

[0003] Referring to a thermal conductivity testing device for rock wool thermal insulation boards disclosed in the patent application with the publication number CN217007088U, a heat source component is set to heat the air in the heating cavity, and the temperature change in the heat transfer cavity is observed to test the thermal conductivity of the rock wool thermal insulation board. This thermal conductivity testing device for rock wool thermal insulation boards has a high degree of integration and a small floor area, which can greatly facilitate the testing of rock wool thermal insulation boards and is convenient for evaluating the quality of rock wool thermal insulation boards.

[0004] The above-mentioned inoculation device in the prior art has the following defects in actual use:

[0005] 1. Only two temperature sensors are set in the test box to test the heat conduction effect of the board. However, different positions inside the board are extremely likely to have different heat transfer capabilities due to production defects. A single temperature sensor can only measure the overall temperature in the space on one side of the board, and cannot measure the temperature at different spatial positions on the same side of the board, making it difficult to obtain accurate data on the heat transfer performance of the board.

[0006] 2. In actual use, multiple boards need to be spliced together. The method of setting temperature sensors at fixed positions cannot obtain the temperature of the joint area of the board, so the heat transfer test data of the joint position in the actual use environment of the board cannot be obtained, resulting in the inability to comprehensively analyze the heat transfer performance of the board.

[0007] Therefore, the present invention proposes an external thermal insulation heat transfer testing device for integrated thermal insulation and decoration boards to solve the above problems. Summary of the Invention

[0008] In view of the deficiencies of the prior art, the present invention provides an external thermal insulation heat transfer test device for an integrated thermal insulation and decoration board, which solves the problem that in the current test box, only two temperature sensors are set to test the thermal conductivity of the board. However, due to production defects, different positions inside the board are extremely likely to have different heat transfer capabilities. A single temperature sensor can only measure the overall temperature in one side space of the board, and cannot measure the temperature at different spatial positions on the same side of the board, making it difficult to obtain accurate data on the heat transfer performance of the board. Moreover, in the actual use process of the board, multiple boards need to be spliced together, and the method of setting temperature sensors at fixed positions cannot obtain the temperature of the joint area of the board, resulting in the inability to obtain the heat transfer test data of the joint position in the actual use environment of the board, and thus unable to comprehensively analyze the heat transfer performance of the board.

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions: An external thermal insulation heat transfer test device for an integrated thermal insulation and decoration board includes a detection box and an operation window opened on the front surface of the detection box. A sealing plate for sealing it is rotatably arranged in the operation window, and further includes:

[0010] A board clamping mechanism is arranged at the middle position inside the detection box, which is used to clamp and fix the positions of integrated thermal insulation and decoration boards with different sizes, and simultaneously seal the positions in contact with the integrated thermal insulation and decoration boards.

[0011] A heat source assembly is arranged on the left side inside the detection box, which is used to convey hot air with a preset temperature to the surface of the integrated thermal insulation and decoration board to be tested according to the heat transfer test requirements.

[0012] A first temperature detection mechanism is arranged in the space between the board clamping mechanism and the heat source assembly, which is used to obtain the temperatures of different regions of the integrated thermal insulation and decoration board in this space at different time periods during the test.

[0013] A second temperature detection mechanism is arranged in the space on the right side of the board clamping mechanism, which is used to obtain the temperatures of different regions on the outer wall of the integrated thermal insulation and decoration board away from the heat source assembly at different time periods during the test. By comparing the temperature differences on both sides of the integrated thermal insulation and decoration board, the quality of the heat transfer performance of the integrated thermal insulation and decoration board can be judged.

[0014] Furthermore, the board clamping mechanism includes a first clamping arm assembly and a second clamping arm assembly, and a gap filling plate for blocking the remaining clamping space after clamping the integrated thermal insulation and decoration board is also arranged between the first clamping arm assembly and the second clamping arm assembly.

[0015] Further, the first clamping arm assembly and the second clamping arm assembly have the same structure. The first clamping arm assembly includes a clamping seat fixedly arranged at the top inside the detection box and a lifting groove opened at the bottom of the clamping seat. A lifting plate is slidably arranged inside the lifting groove, and the lifting plate and the clamping seat are locked by a fastening bolt. A limiting groove for limiting the position of the thermal insulation decorative integrated board is opened at the bottom of the lifting plate, and a rubber sealing pad for enhancing the sealing performance between the lifting plate and the thermal insulation decorative integrated board is fixedly arranged on the inner wall of the limiting groove.

[0016] Further, scale wire grooves for measuring the upward or downward height of the lifting plate are uniformly opened on the front surface of the lifting plate, and pointers for indicating the positions of the scale wire grooves are fixedly arranged on both sides of the front side wall of the clamping seat.

[0017] Further, the heat source assembly includes a hot air box fixedly arranged inside the detection box. A plurality of electric heating tubes are uniformly fixedly arranged inside the hot air box. An installation through hole is opened on the side wall of the hot air box close to the plate clamping mechanism, and a blower for conveying heat towards the plate clamping mechanism is rotatably arranged inside the installation through hole.

[0018] Further, the second temperature detection mechanism has the same structure as the first temperature detection mechanism. The second temperature detection mechanism includes a longitudinal position control component one and a longitudinal position adjustment component two arranged on the inner wall of the detection box. A temperature measurement component one and a temperature measurement component two for measuring the temperature near the outer wall of the thermal insulation decorative integrated board are respectively arranged inside the longitudinal position control component one and the longitudinal position adjustment component two. A temperature measurement component three for measuring the temperature in the middle position area of the thermal insulation decorative integrated board is further arranged between the temperature measurement component one and the temperature measurement component two. A transverse position adjustment component for adjusting the temperature measurement positions of the temperature measurement component one and the temperature measurement component two in the transverse direction is further arranged on the outer wall of the detection box. When the temperature measurement positions of the temperature measurement component one and the temperature measurement component two change in the transverse direction, they are driven by the longitudinal position control component one and the longitudinal position adjustment component two at the corresponding positions, and the temperature measurement positions in the longitudinal direction are synchronously adjusted.

[0019] Further, the longitudinal position control component one and the longitudinal position adjustment component two have the same structure. The longitudinal position control component one includes a bracket fixedly arranged on the side wall of the detection box. Inclined grooves are symmetrically opened at the upper and lower positions on the outer wall of the bracket. Cleaning ring frames are fixedly arranged on the side wall of the bracket and at positions corresponding to each inclined groove.

[0020] Further, the second temperature measuring component has the same structure as the first temperature measuring component. The first temperature measuring component includes a vertical plate and a first sliding sleeve fixedly arranged on one side of the outer wall of the vertical plate. A driving rod is also fixedly arranged on the side wall of the first sliding sleeve away from the vertical plate. The upper and lower sides of the outer wall of the vertical plate are respectively slidably sleeved with a second temperature measuring unit and a first temperature measuring unit for simultaneously measuring the temperatures of different areas on the side wall of the thermal insulation decorative integrated board.

[0021] The second temperature measuring unit and the first temperature measuring unit have the same structure. The first temperature measuring unit includes a second sliding sleeve slidably sleeved on the outer wall of the vertical plate. A support rod is fixedly arranged on the side wall of the second sliding sleeve facing away from the first sliding sleeve. And a temperature sensor is fixedly arranged at one end of the support rod away from the second sliding sleeve.

[0022] Further, the lateral position adjusting component includes a transmission shaft rotatably arranged on the inner wall of the detection box and a servo motor fixedly arranged on the outer wall of the detection box. The output shaft of the servo motor rotates through the detection box and is connected to one end of the transmission shaft through a coupling. Annular grooves and two spiral driving grooves are respectively formed on the outer wall of the transmission shaft. The two spiral driving grooves are symmetrically arranged on both sides of the annular groove. And a guide plate is fixedly arranged on the inner wall of the detection box and on one side of the transmission shaft.

[0023] The present invention also discloses a method for testing the external thermal insulation heat transfer of a thermal insulation decorative integrated board, which is used for a device for testing the external thermal insulation heat transfer of a thermal insulation decorative integrated board. The method includes the following steps:

[0024] Step 1: Place the thermal insulation decorative integrated board into the plate clamping mechanism for clamping. After closing the sealing plate, a relatively independent sealed state is formed in the spaces where the first temperature detection mechanism and the second temperature detection mechanism are located.

[0025] Step 2: Turn on the heat source component to convey hot air at a preset temperature towards the thermal insulation decorative integrated board. After the temperature in the space where the first temperature detection mechanism is located is in a relatively stable state, record the temperature data in the spaces on both sides of the plate clamping mechanism respectively.

[0026] Step 3: Observe the change situation of the temperature value in the space where the second temperature detection mechanism is located. If the temperature difference in the space where the second temperature detection mechanism is located is relatively large compared with the initial temperature, the heat insulation performance of the thermal insulation decorative integrated board is poor. On the contrary, the heat insulation performance of the thermal insulation decorative integrated board is excellent.

[0027] The present invention provides a device for testing the external thermal insulation heat transfer of a thermal insulation decorative integrated board. Compared with the prior art, it has the following beneficial effects:

[0028] An external thermal insulation heat transfer test device for an integrated thermal insulation and decoration board can measure the temperatures of the relatively enclosed spaces on both sides of the integrated thermal insulation and decoration board by setting a first temperature detection mechanism and a second temperature detection mechanism. By comparing the temperature changes on both sides of the integrated thermal insulation and decoration board, the quality of the heat transfer performance of the integrated thermal insulation and decoration board can be reflected. A longitudinal position adjustment component and a transverse position adjustment component are set in the second temperature detection mechanism, and the two can cooperate with each other to adjust the positions of the first temperature measurement unit and the second temperature measurement unit at the same time. That is, when the transverse position adjustment component adjusts the transverse positions of the first temperature measurement component and the second temperature measurement component, the longitudinal position adjustment component simultaneously adjusts the longitudinal positions of the first temperature measurement unit and the second temperature measurement unit in the first temperature measurement component and the second temperature measurement component, so that the first temperature measurement unit and the second temperature measurement unit can be respectively located at multiple temperature measurement points during the test period, and then the temperature values in different areas of the outer wall of the integrated thermal insulation and decoration board can be obtained. According to multiple measured temperature values, not only the overall heat transfer performance of the integrated thermal insulation and decoration board can be analyzed, but also the local heat transfer performance of the integrated thermal insulation and decoration board can be understood, which is beneficial to comprehensively analyze the heat transfer performance of the integrated thermal insulation and decoration board.

[0029] An external thermal insulation heat transfer test device for an integrated thermal insulation and decoration board can obtain the temperature values in different areas of the joint position of two integrated thermal insulation and decoration boards in a spliced state by changing the detection positions of the first temperature measurement unit and the second temperature measurement unit during the heat transfer detection, so as to simulate the heat transfer performance of the joint position of the integrated thermal insulation and decoration board in the actual installation state, making the test data highly reliable.

[0030] 3. An external thermal insulation heat transfer test device for an integrated thermal insulation and decoration board can use the mutual cooperation of the first clamping arm assembly, the second clamping arm assembly and the gap filling plate through the setting of the plate clamping mechanism, so that the two lifting plates can clamp integrated thermal insulation and decoration boards of various sizes, improving its application range. Moreover, when the integrated thermal insulation and decoration board is smaller than the length of the lifting plate, the gap filling plate used in conjunction with the integrated thermal insulation and decoration board of this size can block the remaining clamping space after the first clamping arm assembly and the second clamping arm assembly clamp the integrated thermal insulation and decoration board, so that the gap filling plate and the integrated thermal insulation and decoration board jointly form a structure with the same length as the lifting plate, laying a foundation for forming relatively independent enclosed spaces on both sides of the plate clamping mechanism, making the size requirements for the integrated thermal insulation and decoration boards that the plate clamping mechanism can clamp more extensive and having high practicability.

[0031] 4. An external thermal insulation heat transfer test device for an integrated thermal insulation and decoration board can clean the detection end of the temperature sensor by using the cleaning brush hairs on its inner wall when the first temperature measurement unit or the second temperature measurement unit passes through the cleaning ring frame arranged on the bracket, preventing the situation of reduced temperature measurement sensitivity due to dust adhesion and ensuring the accuracy of temperature measurement.

By comparing the temperature differences on both sides of the thermal insulation decorative integrated board, the pros and cons of the heat transfer performance of the thermal insulation decorative integrated board can be judged.

[0053] As Figures 4 - 5 shows the second embodiment. The difference from the first embodiment is that: the plate clamping mechanism 3 includes a first clamping arm assembly and a second clamping arm assembly 39.

[0054] AsFigures 7 - 13The third implementation manner is shown. The difference from the second implementation manner is that the structures of the second temperature detection mechanism 6 and the first temperature detection mechanism 5 are the same. The second temperature detection mechanism 6 includes a first longitudinal position control component 61 and a second longitudinal position adjustment component 62 provided on the inner wall of the detection box 1. Inside the first longitudinal position control component 61 and the second longitudinal position adjustment component 62, a first temperature measurement component 63 and a second temperature measurement component 64 for measuring the temperature near the outer wall of the thermal insulation decorative integrated board are respectively provided. Between the first temperature measurement component 63 and the second temperature measurement component 64, a third temperature measurement component 65 for measuring the temperature in the middle position area of the thermal insulation decorative integrated board is also provided. On the outer wall of the detection box 1, a lateral position adjustment component 66 for adjusting the temperature measurement positions of the first temperature measurement component 63 and the second temperature measurement component 64 in the lateral direction is further provided. And when the first temperature measurement component 63 and the second temperature measurement component 64 change their temperature measurement positions in the lateral direction, they are driven by the first longitudinal position control component 61 and the second longitudinal position adjustment component 62 at the corresponding positions to synchronously adjust their temperature measurement positions in the longitudinal direction. The distance between the temperature measurement ends of the first temperature measurement component 63 and the second temperature measurement component 64 and the outer wall of the lifting plate 33 is one centimeter. The structures of the first longitudinal position control component 61 and the second longitudinal position adjustment component 62 are the same. The first longitudinal position control component 61 includes a bracket 611 fixedly provided on the side wall of the detection box 1. Inclined grooves 612 are symmetrically formed in the upper and lower positions on the outer wall of the bracket 611.

On the side wall of the first sliding sleeve 632 away from the vertical plate 631, a driving rod 633 is further fixedly provided. On the upper and lower sides of the outer wall of the vertical plate 631, a second temperature measurement unit 635 and a first temperature measurement unit 634 for simultaneously measuring the temperatures of different areas on the side wall of the thermal insulation decorative integrated board are respectively slidably sleeved. The structures of the second temperature measurement unit 635 and the first temperature measurement unit 634 are the same. The first temperature measurement unit 634 includes a second sliding sleeve 6341 slidably sleeved on the outer wall of the vertical plate 631. On the side wall of the second sliding sleeve 6341 away from the first sliding sleeve 632, a support rod 6342 is fixedly provided. And at the end of the support rod 6342 away from the second sliding sleeve 6341, a temperature sensor 6343 is fixedly provided.

And the driving rod 633 is slidably arranged in the corresponding annular groove 663 or spiral driving groove 664. The support rod 6342 slidably penetrates through the corresponding inclined groove 612 and extends to the outside. The cleaning ring frame 613 has an arched structure. The inlet and outlet of the cleaning ring frame 613 are perpendicularly arranged with the corresponding inclined groove 612. And the internal height and width of the cleaning ring frame 613 are much larger than the size of the temperature sensor 6343. A plurality of bristles are uniformly fixedly provided on the inner wall of the cleaning ring frame 613 for cleaning the outer wall of the passing temperature sensor 6343;The temperature sensor 6343 is connected to an external terminal device through wireless communication, and can transmit the temperature data obtained in real time into the terminal device; the lateral position adjustment assembly 66 includes a transmission shaft 661 rotatably arranged on the inner wall of the detection box 1 and a servo motor 662 fixedly arranged on the outer wall of the detection box 1. The output shaft of the servo motor 662 rotates through the detection box 1 and is connected to one end of the transmission shaft 661 through a coupling.

The two spiral drive grooves 664 are symmetrically arranged on both sides of the annular groove 663, and a guide plate 665 is fixedly arranged on the inner wall of the detection box 1 and on one side of the transmission shaft 661.;

[0055] An embodiment of the present invention also provides a method for testing the external heat transfer of an integrated thermal insulation and decoration board, which is used for an external heat transfer test device of an integrated thermal insulation and decoration board. The method includes the following steps:

[0056] Step 1: Place the integrated thermal insulation and decoration board into the plate clamping mechanism 3 for clamping. After closing the sealing plate 2, a relatively independent closed state is formed in the spaces where the first temperature detection mechanism 5 and the second temperature detection mechanism 6 are located; the specific process is as follows: The present invention can be used to clamp and measure the temperature of a variety of known sizes and specifications of integrated thermal insulation and decoration boards. The initial distance between the opposite ends of the lifting plates 33 in the first clamping arm assembly and the second clamping arm assembly is a preset value. For integrated thermal insulation and decoration boards of different specifications and sizes, there are corresponding size gap filling plates 38 for clamping. When the integrated thermal insulation and decoration board is clamped between the two lifting plates 33, in the case where the integrated thermal insulation and decoration board is shorter than the length of the lifting plate 33, the corresponding size gap filling plate 38 can be installed between the two lifting plates 33, so that the gap filling plate 38 and the integrated thermal insulation and decoration board together form a structure with the same length as the lifting plate 33. If the integrated thermal insulation and decoration board to be tested has the same length as the lifting plate 33, there is no need to use the gap filling plate 38 accessory here;

[0057] Therefore, when placing the insulation and decoration integrated board to be tested into the board clamping mechanism 3, adjust the positions of the lifting plates 33 in the first clamping arm assembly and the second clamping arm assembly according to the size of the insulation and decoration integrated board to be tested. When adjusting the position of the lifting plate 33, refer to the position of the scale groove 36 on the front surface of the lifting plate 33 relative to the pointer 37 in the initial position, and then loosen the fastening bolt 34 to move the lifting plate 33 upward or downward so that the distance between the inner walls of the two limiting grooves 35 in the first clamping arm assembly and the second clamping arm assembly is adapted to the height of the insulation and decoration integrated board. Then, tighten the fastening bolt 34 to lock the position of the lifting plate 33. Next, push one end of the insulation and decoration integrated board to be tested along the inner walls of the upper and lower limiting grooves 35 towards the inside of the detection box 1 until one end of the insulation and decoration integrated board abuts against the inner wall of the detection box 1. When the insulation and decoration integrated board is shorter than the length of the lifting plate 33, take the gap filling plate 38 used in cooperation with this type of insulation and decoration integrated board and continue to insert it between the two lifting plates 33 so that the gap filling plate 38 and the insulation and decoration integrated board jointly form a structure with the same length as the lifting plate 33. Then, close the sealing plate 2. During this process, the inner wall of the sealing plate 2 is closely attached to one end of the first clamping arm assembly and the second clamping arm assembly 39, so that the spaces where the first temperature detection mechanism 5 and the second temperature detection mechanism 6 are located respectively form relatively enclosed spaces;

[0058] Regulate the heating power of the heat source assembly 4 with the aid of the control box. The blower 44 extracts the hot air inside the hot air box 41 and conveys it towards the board clamping mechanism 3. Observe the temperature of the space where the first temperature detection mechanism 5 is located through the terminal device. When the temperature in this space reaches a relatively stable value, the terminal device starts to record the temperatures of the spaces where the first temperature detection mechanism 5 and the second temperature detection mechanism 6 are located. During the temperature measurement process, start the servo motor 662 to drive the transmission shaft 661 to rotate a certain angle according to the preset instruction. The driving rods 633 in the first temperature measurement component 63 and the second temperature measurement component 64 slide along the spiral driving grooves 664 at the corresponding positions, so that the first temperature measurement component 63 and the second temperature measurement component 64 move away from each other or approach each other synchronously. At the same time, the support rods 6342 in the second temperature measurement unit 635 and the first temperature measurement unit 634 slide along the inclined grooves 612 at the corresponding positions. Since the inclined grooves 612 at the upper and lower positions are symmetrically designed, while the first temperature measurement component 63 and the second temperature measurement component 64 move horizontally, the two second temperature measurement units 635 at the upper and lower positions approach each other or move away from each other synchronously, so that the positions of the first temperature measurement unit 634 or the second temperature measurement unit 635 in the horizontal and vertical directions are both adjusted, realizing the temperature measurement of different regions on the side wall of the insulation and decoration integrated board. And when testing the heat transfer performance of the splicing state of two insulation and decoration integrated boards, the position of the first temperature measurement unit 634 or the second temperature measurement unit 635 can be adjusted to the joint position to realize the temperature measurement operation of the joint area;

[0059] After the temperature measurement operation is completed, analyze the temperature change in the space where the first temperature detection mechanism 5 and the second temperature detection mechanism 6 are located in the terminal device. If the temperature change in the space where the second temperature detection mechanism 6 is located is relatively small compared to the initial value, it indicates that the heat insulation performance of the surface thermal insulation and decoration integrated board is excellent.

[0060] Step 2: Turn on the heat source component 4 to convey hot air at a preset temperature towards the thermal insulation and decoration integrated board. After the temperature in the space where the first temperature detection mechanism 5 is located is in a relatively stable state, record the temperature data in the spaces on both sides of the plate clamping mechanism 3 respectively.

[0061] Step 3: Observe the change in the temperature value in the space where the second temperature detection mechanism 6 is located. If the temperature in the space where the second temperature detection mechanism 6 is located is relatively different from the initial temperature, it indicates that the heat insulation performance of the thermal insulation and decoration integrated board is poor. On the contrary, the heat insulation performance of the thermal insulation and decoration integrated board is excellent.
