[0001] This application relates to the technical field of door and window detection, and particularly to a device for detecting the heat insulation performance of energy-saving doors and windows. Background Art
[0002] The heat insulation performance of doors and windows is one of the important indicators for measuring the quality of doors and windows. This performance directly affects the heat insulation effect in summer and the warmth retention effect in winter of a building. In order to accurately evaluate this performance of doors and windows, a device for detecting the heat insulation performance of doors and windows has become a commonly used test tool.
[0003] For an existing device for detecting the heat insulation performance of doors and windows, in order to ensure the comprehensiveness of test results, it is often necessary to separately test the isolation effects of doors and windows on heat radiation and heat transfer. In the heat transfer test, a scenario of insulating a closed space is often simulated. A door and window model is installed on one side wall of the closed space, and the temperature inside the closed space is increased by a heat source such as an electric heating wire. Then, the heat source is turned off, and the temperature reduction situation inside the closed space is tested. In the heat radiation test, a scenario of sunlight irradiation needs to be simulated. A door and window model is installed on one side wall of the closed space, and the door and window is irradiated with a heat lamp outside the closed space to detect the temperature increase situation inside the closed space.
[0004] In the process of implementing this application, it is found that there are at least the following problems in this technology: During the two tests, two heat sources need to be used separately for heating, which consumes a large amount of energy and is not conducive to energy conservation and environmental protection. Summary of the Utility Model

[0006] The device for detecting the heat insulation performance of energy-saving doors and windows provided by this application adopts the following technical solutions:
[0007] A device for detecting the heat insulation performance of energy-saving doors and windows includes a detection box and a vacuum transparent plate. An insertion opening is provided at the top of the detection box, and the insertion opening can be used for inserting the vacuum transparent plate and the door and window model to be tested simultaneously. The inside of the detection box on one side of the insertion opening is set as an irradiation chamber, and the inside of the detection box on the other side of the slot is set as a temperature measurement chamber. A fixing frame is fixedly arranged near the insertion opening in the temperature measurement chamber. A fixing component is also arranged on the detection box, and the fixing component is used to fix the door and window model on the fixing frame. A heat lamp is fixedly arranged in the irradiation chamber. A group of ventilation openings are provided on both side walls of the irradiation chamber, and a baffle for closing the ventilation openings is arranged on the ventilation openings. A temperature sensor is installed in the temperature measurement chamber.
[0008] By adopting the above technical solution, a thermal radiation barrier test is carried out: the barrier plate closes the vent, the door and window model and the vacuum transparent plate are inserted into the test box from the socket at the same time, and then the door and window model and the vacuum transparent plate are fixed on the fixing frame through the fixing assembly. At this time, the temperature measuring chamber forms a closed space, and then the heat lamp is turned on to irradiate the door and window model. The light passes through the vacuum transparent plate and the door and window model, and is converted into heat in the temperature measuring chamber. The temperature sensor detects the temperature, and the temperature rise change is observed. The heat accompanied by the heat lamp and the infrared light reflected by the door and window model are retained in the irradiation chamber, and the vacuum transparent plate blocks these heat. The amount of heat is brought into contact with the door and window model through heat transfer; then the heat transfer barrier test is immediately carried out: first, the door and window model is loosened through the fixing assembly, and the door and window model and the vacuum transparent plate are pulled up (not completely separated) to allow the heat in the irradiation chamber to enter the temperature measuring chamber, then the door and window model is put down and the vacuum transparent plate is completely pulled out, and the door and window model is re-fixed on the fixing frame through the fixing assembly, and then the heat lamp is turned off and the barrier plate is opened to allow the heat in the irradiation chamber to overflow, and finally, the temperature reduction change detected by the temperature sensor is observed; in this process, only one heat source, the heat lamp, is used, which reduces the waste of heat energy during the test.

[0010] By adopting the above technical solution, the heat absorbing plate quickly absorbs light and converts it into heat, thereby preventing the light entering the temperature measuring chamber from being reflected again by the inner wall of the temperature measuring chamber, thereby improving the sensitivity of the temperature sensor to light and heat.
[0011] Preferably, a sealing strip is fixedly arranged around the side wall of the fixing frame, and the sealing strip can be abutted against the door and window model.
[0012] By adopting the above technical solution, when the door and window model is fixed on the fixing frame, the sealing strip and the door and window model are abutted against each other, thereby improving the sealing of the temperature measuring chamber, thereby improving the accuracy of the measurement result.

The rotating wheel is rotatably arranged on the inner wall of the irradiation chamber, and the knob is rotatably arranged on the outer wall of the irradiation chamber. The knob passes through the irradiation chamber and is coaxially fixed with the rotating wheel. The protrusion is fixed on the peripheral wall of the rotating wheel, and the protrusion can be pressed against the side of the door and window model facing away from the fixing frame.
[0014] By adopting the above technical solution, when the door and window model needs to be fixed on the fixing frame, the knob is turned, the knob drives the wheel to rotate, the protrusion presses against the side of the door and window model away from the fixing frame, and the door and window model is firmly clamped between the fixing frame and the protrusion.
[0015] Preferably, the bump is made of rubber material.
[0016] By adopting the above technical solution, the rubber bump has elasticity, so that whether a vacuum transparent plate is inserted into the socket or not, it can play a fixing role for the door and window model.
[0017] Preferably, the partition plate is vertically slidably arranged in the ventilation opening, the top of the partition plate extends out from the top end of the ventilation opening, a synchronous plate is fixedly connected to the tops of the two partition plates, and a lifting spring is arranged between the bottom surface of the synchronous plate and the top of the detection box, and the lifting spring drives the synchronous plate away from the top of the detection box.
[0018] By adopting the above technical solution, when the ventilation opening is opened, the lifting spring drives the synchronous plate away from the top of the detection box, and the synchronous plate drives the partition plates on both sides to lift at the same time and keeps the lifted state.
[0019] Preferably, a lock catch is horizontally slidably arranged on the top of the detection box, a lock hole is formed in the inner side wall of the partition plate, and the lock catch can be inserted into the lock hole and abutted against the inner wall of the lock hole.
[0020] By adopting the above technical solution, when closing the partition plate, slide the lock catch and insert it into the lock hole, and the lock catch abuts against the inner wall of the lock hole to prevent the partition plate from lifting, realizing the quick closing and locking of the partition plate.
[0021] Preferably, a control screen is installed on the detection box, and the control screen is communicatively connected with the thermal lamp and the temperature sensor.

Detailed implementation manners
[0030] The following will further elaborate on the present application in conjunction with the Figure 1-2 accompanying drawings.
[0031] An embodiment of the present application discloses a device for detecting the heat insulation performance of energy-saving doors and windows. Refer to Figure 1 and Figure 2 , which includes a detection box 1 and a vacuum transparent plate 2 for transmitting light and isolating heat. A socket 11 is opened at the top of the detection box 1. When performing the heat radiation barrier test, the vacuum transparent plate 2 and the door and window model to be tested are inserted into the detection box 1 together from the socket 11. The inside of the detection box 1 on one side of the socket 11 is set as an irradiation chamber 12, and the other side is set as a temperature measurement chamber 13. A fixing frame 131 is fixedly arranged near the socket 11 in the temperature measurement chamber 13. A sealing strip 1311 is fixedly arranged on the side wall of the fixing frame 131(131), and the sealing strip 1311 abuts against the door and window model, so as to form a sealed space between the door and window model and the temperature measurement chamber 13. A fixing component 3 is arranged on the detection box 1, and the fixing component 3 is used to fix the door and window model on the fixing frame 131 to improve the stability of the sealed space. A black heat absorption plate 132 and a temperature sensor 133 are fixed in the temperature measurement chamber 13, and the temperature sensor 133 is designed on the heat absorption plate 132. A heat lamp 121 is fixedly arranged in the irradiation chamber 12. A control panel 14 is installed on the detection box 1, and the control panel 14 is communicatively connected with the heat lamp 121 and the temperature sensor 133 to display the detection data of the temperature sensor 133 in real time. The heat lamp 121 is controlled by the control panel 14 to irradiate the door and window model. The light passes through the vacuum transparent plate 2 and the door and window model and is converted into heat on the heat absorption plate 132. The change in the temperature rise of the heat absorption plate 132 is captured and detected by the temperature sensor 133, and the temperature change situation is displayed on the control panel 14, so as to perform the heat radiation barrier test.
[0032] Refer to Figure 1With Figure 2 , immediately conduct a heat transfer barrier test. Loosen the door and window model by the fixing component 3, and pull up the door and window model and the vacuum transparent plate 2 (without completely pulling out). The heat in the irradiation chamber 12 enters the temperature measurement chamber 13. Then put down the door and window model, and completely extract the vacuum transparent plate 2. The fixing component 3 fixes the door and window model again. A set of ventilation openings 122 are provided on both side walls of the irradiation chamber 12, and a baffle 1221 for closing the ventilation openings 122 is provided on the ventilation openings 122. Turn off the heat lamp 121 and open the baffle 1221, so that the heat in the irradiation chamber 12 dissipates from the ventilation openings 122, and the temperature sensor 133 detects the temperature drop in the temperature measurement chamber 13.
[0033] In order to fix the door and window model on the fixing frame 131, refer to Figure 1 With Figure 2 , the fixing component 3 includes a knob 31, a runner 32, and a convex block 33. The runner 32 is rotatably arranged on the inner wall of the irradiation chamber 12, the knob 31 is rotatably arranged on the outer wall of the irradiation chamber 12, the knob 31 penetrates through the irradiation chamber 12 and is coaxially fixed with the runner 32, and the convex block 33 is fixedly arranged on the circumferential wall of the runner 32. The convex block 33 is made of rubber material, which has elasticity and can produce large deformation. The convex block 33 can abut against the door and window model or the vacuum transparent plate 2. Rotate the knob 31 to drive the runner 32 to deflect, and the convex block 33 abuts against the door and window model or the transparent vacuum template, and the door and window model is firmly clamped and fixed.
[0034] In order to facilitate the control of the opening and closing of the ventilation openings 122, refer to Figure 1 , a latch 1224 is horizontally slidably arranged on the top of the detection box 1. A lock hole 1225 is opened on the inner side wall of the baffle 1221, and the latch 1224 can be inserted into the lock hole 1225 and abut against the inner wall of the lock hole 1225. When closing the baffle 1221, slide the latch 1224 and insert it into the lock hole 1225. The latch 1224 abuts against the inner wall of the lock hole 1225, preventing the baffle 1221 from being lifted. The baffle 1221 is vertically slidably arranged in the ventilation opening 122. The top of the baffle 1221 extends out from the top end of the ventilation opening 122. A synchronous plate 1222 is fixedly arranged on the tops of the two baffles 1221. A lifting spring 1223 is arranged between the bottom surface of the synchronous plate 1222 and the top of the detection box 1, and the lifting spring 1223 drives the synchronous plate 1222 away from the top of the detection box 1. When opening the ventilation opening 122, slide the latch 1224 out of the lock hole 1225. The lifting spring 1223 drives the synchronous plate 1222 away from the top of the detection box 1. The synchronous plate 1222 simultaneously drives the two baffles 1221 on both sides to lift and maintain the lifted state.
[0035] The implementation principle of an energy-saving door and window heat insulation performance detection device according to an embodiment of the present application is as follows: First, perform a thermal radiation test. Close the ventilation opening 122, and insert the door and window model and the vacuum transparent plate 2 into the detection box 1 at the same time. Rotate the knob 31 to tightly fix the door and window model and the vacuum transparent plate 2 on the fixing frame 131. At this time, the temperature measurement chamber 13 forms a sealed space. Turn on the heat lamp 121 to irradiate the door and window model. The light passes through the vacuum transparent plate 2 and the door and window model and is converted into heat on the heat absorption plate 132. The temperature detected by the temperature sensor 133 is reflected on the control screen 14. The heat generated by the heat lamp 121 during lighting and the infrared light reflected by the door and window model are retained in the irradiation chamber 12, and the vacuum transparent plate 2 blocks the heat from contacting the door and window model through heat transfer.
[0036] Then, immediately perform a heat transfer blocking test. Loosen the door and window model, and pull up the door and window model and the vacuum transparent plate 2 upward so that the heat in the irradiation chamber 12 enters the temperature measurement chamber 13. Put down the door and window model and completely remove the vacuum transparent plate 2, refix the door and window model on the fixing frame 131, then turn off the heat lamp 121 and open the baffle 1221 to let the heat in the irradiation chamber 12 dissipate. Observe the change in the temperature reduction of the temperature measurement chamber 13 detected by the temperature sensor 133. It is convenient to detect the heat transfer and thermal radiation isolation effects of the door and window, reduce the use of heat sources, and save energy consumption during testing.
[0037] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
