Description

Technical Field

[0001] The utility model belongs to the technical field of energy-saving building materials, and in particular relates to a device for detecting the thermal insulation performance of energy-saving building materials. Background Art

Therefore, energy-saving building materials need to be tested for thermal insulation performance after production to determine the thermal insulation performance of the energy-saving building materials and facilitate improving the thermal insulation effect of houses built with energy-saving building materials.

[0003] In the prior art, the application number is CN202222509708.2, and the name is a thermal insulation performance testing device for thermal insulation materials for construction projects. It discloses a thermal insulation performance testing device for thermal insulation materials for construction projects, including a testing platform and a computer processor. The top of the testing platform is provided with a groove, and a heat conduction plate is installed on the top of the groove. A heating chamber is provided inside the testing platform, and an electric heating tube is installed in the heating chamber. Support frames are installed on both sides of the top center axis of the testing platform, and a screw rod is rotatably connected between the two support frames. One end of the screw rod is connected to a servo motor, and a nut seat is installed on the screw rod. An electric push rod is installed at the bottom of the nut seat, and a lower pressure plate is installed on the bottom output shaft of the electric push rod.

[0004] The above patent heats one side of the insulation board through an electric heating tube, and uses a temperature sensor to detect the temperature on the other side of the insulation board, thereby detecting the insulation efficiency of the insulation board. However, the detection of different parts of the insulation board in the device is achieved by a motor and a screw to drive the temperature sensor to move, and it is not completed at the same time. The temperature of the surface of the insulation board may change with time, which may lead to inaccurate detection results. In view of this, the present utility model is specially proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for detecting the thermal insulation performance of energy-saving building materials that can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a thermal insulation performance testing device for energy-saving building materials, including a testing platform, an electric heating tube is fixedly installed in the testing platform, a thermometer is installed on one side of the testing platform, and the detection end of the thermometer extends into the testing platform, and also includes: a placement frame bar, fixedly connected to a position inside the testing platform near the upper end opening; a lifting plate, which is arranged above the testing platform through a lifting assembly, and the lifting plate is a transparent plate; an installation groove is opened on the lower surface of the lifting plate; a temperature-sensitive color-changing plate is installed in the installation groove of the lifting plate, and the lower surface of the temperature-sensitive color-changing plate is flush with the lower surface of the lifting plate.

[0007] Furthermore, two first electric telescopic rods are symmetrically fixedly connected in the detection table, and an ejection plate is provided between the two first electric telescopic rods. The two sides of the ejection plate are fixedly connected to the telescopic ends of the two first electric telescopic rods, and the first electric telescopic rods are high-temperature resistant electric telescopic rods.

[0008] Furthermore, the lifting assembly includes an L-shaped support plate and a second electric telescopic rod. The L-shaped support plate is symmetrically fixedly connected to both sides of the detection platform. The second electric telescopic rod is fixedly connected to the L-shaped support plate. The telescopic end of the second electric telescopic rod is fixedly connected to the lifting plate.

[0009] In order to ensure the uniformity of the pressure applied by the thermochromic plate to the thermal insulation board, a limiting notch is further provided on the lifting plate near the L-shaped support plate, and the lifting plate slides against the L-shaped support plate through the limiting notch.

[0010] In order to ensure the sealing between the thermal insulation board and the placement frame strip, a circle of sealing gasket is fixedly connected to the placement frame strip.

[0011] In order to facilitate the control of the pressure value on the insulation board and avoid damaging the insulation board, the sealing gasket is further configured as an airbag ring, and a pressure gauge is fixedly connected to one side of the test platform, and the detection end of the pressure gauge is connected to the inside of the airbag ring.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the present invention uses the detection platform, lifting assembly, transparent lifting plate and temperature-sensitive color-changing plate and other components in combination. Compared with the prior art method of using temperature sensors for detection, when the energy-saving building materials are fixedly installed on the detection platform for detection, the staff can observe the color change of each area of ​​the temperature-sensitive color-changing plate through the transparent lifting plate, so that the thermal insulation effect of the energy-saving building materials can be detected more intuitively, and various parts of the energy-saving building materials can be detected simultaneously, which effectively improves the comprehensiveness and accuracy of the detection of the thermal insulation performance of the energy-saving building materials.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1:

[0021] Reference Figure 1-Figure 3 A device for testing the thermal insulation performance of energy-saving building materials includes a testing platform 1, an electric heating tube 101 is fixedly installed in the testing platform 1, a thermometer 102 is installed on one side of the testing platform 1, and the detection end of the thermometer 102 extends into the testing platform 1, and also includes: a placement frame strip 105, fixedly connected to a position near the upper end opening inside the testing platform 1; a lifting plate 202, which is arranged above the testing platform 1 through a lifting component, and the lifting plate 202 is a transparent plate; an installation groove is opened on the lower surface of the lifting plate 202; a temperature-sensitive color-changing plate 203, which is installed in the installation groove of the lifting plate 202, and the lower surface of the temperature-sensitive color-changing plate 203 is flush with the lower surface of the lifting plate 202.

[0022] Two first electric telescopic rods 103 are symmetrically fixedly connected in the testing platform 1, and an ejection plate 104 is arranged between the two first electric telescopic rods 103. The two sides of the ejection plate 104 are fixedly connected to the telescopic ends of the two first electric telescopic rods 103. The first electric telescopic rods 103 are high-temperature resistant electric telescopic rods.

[0023] The lifting assembly includes an L-shaped support plate 2 and a second electric telescopic rod 201. The L-shaped support plate 2 is symmetrically fixedly connected to both sides of the testing platform 1. The second electric telescopic rod 201 is fixedly connected to the L-shaped support plate 2. The telescopic end of the second electric telescopic rod 201 is fixedly connected to the lifting plate 202.

[0024] Instructions are required. The temperature-sensitive color-changing plate 203 in the device adopts a thermochromic liquid crystal color-changing film, and other common temperature-sensitive color-changing materials on the market can also be used.

[0025] After the energy-saving building materials are produced, when it is necessary to test their thermal insulation performance, the staff will first cut the energy-saving building materials, such as thermal insulation boards, into the specified size, and then control the lifting plate 202 to move up through the second electric telescopic rod 201, thereby opening the testing platform 1, and then the energy-saving building materials can be placed flat on the placement frame 105 in the testing platform 1, and then the lifting plate 202 can be controlled to move down so that the temperature-sensitive color-changing plate 203 on the lower side of the lifting plate 202 fits with the upper surface of the energy-saving building materials, and then the staff can test the electric heating. The heat pipe 101 supplies power to heat the inside of the test platform 1. When the thermometer 102 detects that the temperature inside the test platform 1 has risen to the specified temperature, the heating of the test platform 1 can be stopped. The staff can then observe the color change of each area of ​​the temperature-sensitive color-changing plate 203 through the transparent lifting plate 202, and can intuitively detect the thermal insulation effect of the energy-saving building materials. In addition, the energy-saving building materials can be tested simultaneously in various places, which effectively improves the comprehensiveness and accuracy of the thermal insulation performance test of the energy-saving building materials.

[0026] After the inspection is completed, the first electric telescopic rod 103 can be started, and the first electric telescopic rod 103 can control the energy-saving building material to move upward through the ejection plate 104, so that the energy-saving building material can be ejected from the inspection platform 1.

[0027] Example 2:

[0028] Reference Figure 1-Figure 3 , a thermal insulation performance testing device for energy-saving building materials, is basically the same as Example 1, and further: a limiting notch is opened at the position of the lifting plate 202 near the L-shaped support plate 2, and the lifting plate 202 slides against the L-shaped support plate 2 through the limiting notch.

[0029] By setting the limiting notch, the lifting plate 202 can be clamped on the L-shaped support plate 2, so as to facilitate the limiting and guiding role of the lifting plate 202, ensuring that the lifting plate 202 drives the temperature-sensitive color-changing plate 203 to fit tightly with the insulation board, and the temperature-sensitive color-changing plate 203 applies pressure to the insulation board uniformly, thereby effectively improving the accuracy of the insulation performance detection of the insulation board.

[0030] Example 3:

[0031] Reference Figure 1-Figure 3 , a device for detecting the thermal insulation performance of energy-saving building materials, which is basically the same as Example 2, and further: a circle of sealing gasket 106 is fixedly connected to the placement frame strip 105. By arranging a circle of sealing gasket 106 on the placement frame strip 105, when the insulation board is tightly fitted with the placement frame strip 105 under the downward pressure of the lifting plate 202, the sealing between the insulation board and the placement frame strip 105 can be ensured, thereby avoiding heat loss and affecting the detection accuracy.

[0032] The sealing gasket 106 is an airbag ring, and a pressure gauge 107 is fixedly connected to one side of the test platform 1. The detection end of the pressure gauge 107 is connected to the inside of the airbag ring. By designing the sealing gasket 106 as an airbag ring and arranging a pressure gauge 107 connected to the airbag ring on one side of the test platform 1, when the lifting plate 202 presses down the insulation board, it can not only ensure the sealing between the insulation board and the placement frame strip 105 and avoid temperature loss, but also check the pressure degree of the insulation board according to the air pressure value displayed on the pressure gauge 107, so as to facilitate controlling the pressure value on the insulation board while ensuring the sealing, and avoid damaging the insulation board and affecting the test results.

[0033] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
