[0002] The detection of the dew point of insulating glass is one of the main contents of building energy-saving detection and evaluation. In recent years, with the increasing shortage of fossil energy, the country has attached great importance to building energy conservation. The heat transfer energy consumption of exterior window glass accounts for about 30% of the total energy consumption of buildings in my country, especially in winter heating in the north, which consumes a large proportion of energy each year. The main factor affecting building energy consumption is the thermal insulation performance of the building itself. The national standards "Code for Acceptance of Construction Quality of Energy-Saving Engineering for Buildings" (GB50411-2019) and "Insulating Glass" GBT 11944-2012 promulgated by my country clearly require the detection of the dew point of insulating glass in doors and windows.

[0003] At present, there are many instruments for testing the dew point of insulating glass, but few of them can actually test the insulating glass of doors and windows that have been installed in the construction project. Most of them are to remove the whole window and place it horizontally for testing. Although the test can be carried out, the operation is difficult and does not conform to the actual situation.

[0023] In order to make the purpose, technical scheme and beneficial effects of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments.

[0024] Example 1: Figure 1-2 As shown, the technical solution and technical description of the on-site dew point detector for building insulating glass are as follows:

[0025] 1. The probe 2 and the cylinder 13 are connected to form a closed L-shaped whole, and the outside is provided with a heat-insulating sheath 12. A temperature probe 1 is inserted into the probe 2 to monitor the temperature.

[0026] The top opening of the cylinder 13 is used to fill the cooling medium to adjust or maintain the required temperature. Optionally, the top opening of the cylinder is covered with a sealing cover. The bottom of the cylinder is sealed and connected to the probe to ensure the sealing of the internal environment.

[0027] 2. The clamping block 11 is used to fix the cylinder, and is fixed to the bottom of the cylinder 13 and on the clamp bracket 3 through the clamping screw 9 and the first butterfly nut 10.

[0028] Specifically, a special clamping block 11 is arranged on the clamp bracket 3 for fixing the cylinder. The clamping block is composed of an upper and lower halves, which are connected by a clamping screw and locked by a first butterfly nut 10 to ensure that the cylinder is stable and immovable.

[0029] 3. The fixture bracket 3 is a right angle, with a through hole for inserting the probe 2 on one side, and fixed with the clamping screw 9 and the clamping block 11. The other side of the fixture bracket 3 is fixed to the suction cup connecting rod 5 through the second butterfly nut 7 and the locking screw 8.

[0030] Specifically, the clamp bracket adopts a right-angle structure, which is divided into a vertical part and a horizontal part, providing a stable support for the entire device. Among them, the vertical part is provided with a through hole for the probe to pass through, and the horizontal part is fixed by a locking screw 8, a second butterfly nut and a suction cup connecting rod. In addition, a strip hole is opened on the clamp bracket 3, and the bottom of the locking screw 8 is fixed on the suction cup connecting rod after passing through the strip hole. The top of the locking screw 8 is exposed outside the strip hole and is locked and positioned with the second butterfly nut 7. Among them, the strip hole design of the horizontal part allows the locking screw to be adjusted along its length. In other words, loosen the second butterfly nut 7, and based on the setting of the strip hole, the clamp bracket can move forward and backward along the locking screw 8, and after moving to a suitable position, it is locked and positioned with the second butterfly nut 7.

[0031] 4. The glass suction cup 4 is fixed on the suction cup connecting rod 5 through the suction cup seat 6 and the pin 14.

[0032] 5. The probe 2 is made of copper with a φ50 cylindrical surface, and the cylinder 13 is made of low-temperature resistant engineering plastics.

[0033] 6. The probe 2 and the cylinder together form a closed L-shaped whole, and the outside is equipped with a thermal insulation jacket, which optimizes heat management and reduces the impact of the external environment on the measurement results.

[0034] Example 2: Use of the on-site dew point detector for building insulating glass:

[0035] Step 1: Place the glass suction cup 4 against the insulating glass 16 of the window, move the suction cup handle 15, and the glass suction cup 4 is firmly attached to the glass. Loosen the second butterfly nut 7, move the fixture bracket along the strip hole toward the insulating glass 16, and tighten the second butterfly nut 7 after the probe is in close contact with the glass surface.

[0036] Step 2: Finally, inject ethanol to a depth of about 25 mm into the cylinder 13, and then add dry ice to cool the cylinder 13 to a temperature equal to or lower than -60°C and maintain the temperature during the test. Thus, the field dew point test of the insulating glass of a window is completed according to the standard requirements.

[0037] Embodiment 3: A digital temperature recorder is used to collect the temperature of the probe through a temperature probe, thereby obtaining the actual on-site test temperature. When the temperature reaches the required test temperature, the time is manually counted according to the test standard, thereby completing an on-site dew point detection test.

[0038] The dew point meter of the utility model adopts an L-shaped cylinder structure, and is fixed on the window glass with a large suction glass suction cup on site, which is highly practical. It avoids the many troubles caused by the horizontal test of the entire window that can only be disassembled. The test conforms to the actual situation on site and is simple to operate. It is particularly suitable for on-site dew point detection of insulating glass and is worthy of promotion in the insulating glass detection industry.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. Therefore, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope defined by the claims of the present invention.
