Description

Technical Field

[0001] This invention belongs to the field of building simulation technology, specifically relating to an extreme cold and arid environment simulation chamber. Background Technology

[0002] Glass curtain walls offer advantages such as aesthetics, heat insulation, and sound insulation, and are widely used in modern architecture. However, in Northwest my country, the external weather is cold and arid, while indoor spaces often utilize air conditioning and humidifiers for heating and humidification. This creates a temperature and humidity difference between the inside and outside of the glass curtain wall, making it prone to cracking due to thermal expansion and contraction, posing a safety hazard. Therefore, an environmental simulation chamber is needed to simulate the safety performance of glass curtain walls under the extreme cold and arid conditions of Northwest China, where temperature and humidity differ between the two sides. Summary of the Invention

[0003] In view of this, the present invention discloses an extreme cold and arid environment simulation chamber, the purpose of which is to simulate the extreme cold and arid environment in the Northwest to test the safety performance of glass curtain walls.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An extreme cold and arid environment simulation chamber includes a hollow chamber with a through groove on one side of the middle section and a sliding groove at the bottom of the chamber communicating with the through groove. A mounting frame for installing a glass curtain wall is slidably connected within the sliding groove. The mounting frame is equipped with a power structure for driving its movement, and a rubber layer is provided around its periphery to seal the sliding groove and through groove. Hinged doors are located at both ends of the chamber, each with an air inlet duct communicating with the outside. A fan is installed at the port of the air inlet duct facing the middle of the chamber, and a humidity control box for controlling gas humidity is installed at the other end of the air inlet duct. A heater and a cooler are installed between the fan and the humidity control box. A detector for inspecting the glass curtain wall is mounted on the mounting frame.

[0005] In this test, the glass curtain wall is mounted on a mounting frame, which is then driven by a power structure to slide into the enclosure. Fans in the air intake ducts simultaneously blow air onto the glass curtain wall; concurrently, a humidity control box on one side of the air intake duct reduces the humidity of the airflow and lowers its temperature via a corresponding cooler, while a humidity control box on the other side increases the humidity and lowers the airflow temperature via a corresponding heater. This simulates the operating environment of the glass curtain wall, exposing one side to cold, dry airflow and the other side to warm, humid airflow, thus testing its safety performance. Furthermore, the temperature and humidity of the environment on both sides of the glass curtain wall can be adjusted according to seasonal changes for a more comprehensive assessment of its performance.

[0006] Furthermore, the mounting frame is provided with an adjustment groove, and a support frame is provided in the adjustment groove. Both ends of the support frame are rotatably connected to the adjustment groove with a rotating shaft. An adjustable baffle is provided on the support frame.

[0007] In this solution, by changing the angle of the adjustable baffle, the airflow on both sides of the glass curtain wall converges, thereby simulating the situation of the airflow inside and outside converging when the window is open. This makes the solution more closely resemble the actual usage environment and allows for a more comprehensive test of the glass curtain wall's performance. In addition, by rotating the support frame, the vertical orientation of the window can be simulated, and by changing different angles of the adjustable baffle, different opening angles of the window can be simulated, thus making the simulation data more comprehensive.

[0008] Furthermore, a support block is horizontally arranged within the support frame, and an airbag is provided between one end of the support block and the support frame. Guide rods with telescopic structures are provided on both sides of the airbag, and the two ends of the guide rods are respectively connected to the support frame and the support block. A horizontally arranged support shaft is rotatably connected to the other end of the support block, and a rotating structure for driving the support shaft to rotate is provided on the support block. The adjusting baffle includes a fixed plate body fixed to the support shaft, and an adjusting groove is opened at the end of the fixed plate body. Adjusting plates are slidably connected in the adjusting groove, and a push rod is provided between the adjusting plate body and the fixed plate body.

[0009] In this solution, when it is necessary to isolate the airflow on both sides, the adjusting plate is kept against the supporting frame, and the airbag is inflated. The airbag, fixed plate, and adjusting plate are used to seal the supporting frame, thereby isolating the airflow on both sides of the glass curtain wall. When it is necessary to simulate window opening, the extension and retraction of the guide rod causes the push rod to slide relative to the fixed plate, ensuring that the adjusting plate is against the supporting frame. The airbag always keeps the area between the supporting block and the supporting frame closed, thus simulating windows of different lengths. Then, the rotating structure drives the supporting shaft to rotate, which in turn causes the adjusting baffle to deflect at different angles, thus simulating different window opening situations and making the detection range more comprehensive.

[0010] Furthermore, a connecting ball is fixedly mounted on the air inlet duct, the connecting ball is rotatably mounted on the corresponding movable door, a fixed rod is connected to the connecting ball by a ball hinge, a movable rod is slidably mounted on the end of the fixed rod, and a locking pin is provided between the fixed rod and the movable rod.

[0011] In this solution, removing the locking pin allows the movable rod to slide relative to the fixed rod. At this point, deflecting the connecting ball can adjust the orientation of the air inlet duct, thereby changing the wind direction and simulating the effects of different wind directions on the glass curtain wall. When it is necessary to fix the air inlet duct, simply reset the locking pin to restrict the movable rod from sliding relative to the fixed rod. The operation is simple and quick.

[0012] Furthermore, the humidity control box has a connecting pipe at the end furthest from the air inlet pipe that is connected to the outside, and the connecting pipe is coaxial with the air inlet pipe; a T-shaped bracket is hinged to the side wall of the humidity control box, and humidity pipes parallel to the connecting pipe are fixed at both ends of the bracket; a filter frame is detachably connected to one of the humidity pipes, and a desiccant is placed in the filter frame; a humidifier is installed in the other humidity pipe; a telescopic push rod for pushing the support rod to deflect is provided on the side wall of the humidity control box.

[0013] In this solution, two humidity lines are equipped with filter frames containing desiccant and humidifiers for humidification. When humidification or dehumidification is required, the bracket is deflected by pushing the telescopic push rod so that the corresponding humidity line is located between the air inlet line and the connecting line. The whole operation process is simple and quick.

[0014] Furthermore, annular blocks are slidably fitted at both ends of the humidity pipeline, and bidirectional telescopic rods are provided on the side walls of the humidity pipeline, with the ends of the bidirectional telescopic rods fixedly connected to the corresponding annular blocks.

[0015] Furthermore, a rubber layer is provided on the inner wall of each annular block.

[0016] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0019] like Figures 1-4 As shown: An extreme cold and arid environment simulation chamber includes a hollow chamber 1. A through groove is formed on one side of the middle of the chamber 1, and a sliding groove communicating with the through groove is formed at the bottom of the chamber 1. An installation frame 2 for installing a glass curtain wall is slidably connected in the sliding groove. The installation frame 2 is equipped with a power structure for driving its movement (using an electric motor, which is a conventional technical means and therefore not described in detail). A rubber layer for sealing the sliding groove and through groove is provided around the periphery of the installation frame 2. Both ends of the chamber 1 are hinged with movable doors 3. Each movable door 3 is equipped with an air inlet pipe 4 communicating with the outside. A fan 5 is provided at the port of the air inlet pipe 4 facing the middle of the chamber 1. A humidity control box 8 for controlling the humidity of the gas is provided at the other end of the air inlet pipe 4. A heater 6 and a cooler 7 are provided between the fan 5 and the humidity control box. A detector for testing the glass curtain wall is provided on the installation frame 2.

[0020] In this scheme, the glass curtain wall to be tested is installed on the mounting frame 2, and then the mounting frame 2 is driven by a power structure to slide the mounting frame 2 and the glass curtain wall into the housing 1. Fans 5 in the air inlet duct 4 simultaneously blow air onto the glass curtain wall; at the same time, the humidity control box 8 corresponding to one side of the air inlet duct 4 reduces the humidity of the airflow and lowers the airflow temperature through a corresponding cooler 7, while the humidity control box 8 corresponding to the other side of the air inlet duct 4 increases the humidity of the airflow and lowers the airflow temperature through a corresponding heater 6. This simulates the usage environment of the glass curtain wall, allowing for the testing of its safety performance. Furthermore, the temperature and humidity of the environment on both sides of the glass curtain wall can be adjusted according to seasonal changes for a more comprehensive assessment of the glass curtain wall's performance.

[0021] In this embodiment, the mounting frame 2 is provided with an adjustment groove, and a support frame 9 is provided in the adjustment groove. Both ends of the support frame 9 are rotatably connected to the adjustment groove with a rotating shaft. An adjustable baffle is provided on the support frame 9.

[0022] In this solution, by changing the angle of the adjusting baffle, the airflow on both sides of the glass curtain wall converges, thereby simulating the situation of the airflow inside and outside converging when the window is open. This makes the solution more closely resemble the actual usage environment and allows for a more comprehensive test of the glass curtain wall's performance. In addition, by rotating the support frame 9, the up and down orientation of the window can be simulated, and by changing the different angles of the adjusting baffle, different opening angles of the window can be simulated, thus making the simulation data more comprehensive.

[0023] In this embodiment, a support block 10 is horizontally arranged inside the support frame 9. An airbag 11 is arranged between one end of the support block 10 and the support frame 9. Guide rods 12 with telescopic structures are arranged on both sides of the airbag 11 (electric telescopic rods are used, which is a conventional technical means and therefore not described in detail). The two ends of the guide rods 12 are respectively connected to the support frame 9 and the support block 10. The other end of the support block 10 is rotatably connected to a horizontally arranged support shaft 13. A rotating structure for driving the support shaft 13 to rotate is arranged on the support block 10 (a motor is used, which is a conventional technical means and therefore not described in detail). The adjusting baffle includes a fixed plate 14 fixed to the support shaft 13. An adjusting groove is opened at the end of the fixed plate 14. Adjusting plates 15 are slidably connected in the adjusting groove. A push rod 16 (electric telescopic rods are used, which is a conventional technical means and therefore not described in detail) is arranged between the adjusting plate 15 and the fixed plate 14.

[0024] In this scheme, when it is necessary to isolate the airflow on both sides, the adjusting plate 15 is kept in contact with the supporting frame 9, and the airbag 11 is inflated. The airbag 11, the fixed plate 14, and the adjusting plate 15 are used to seal the supporting frame 9, thereby isolating the airflow on both sides of the glass curtain wall. When it is necessary to simulate window opening, the guide rod 12 extends and retracts, and the push rod 16 drives the adjusting plate 15 to slide relative to the fixed plate 14, ensuring that the adjusting plate 15 is in contact with the supporting frame 9. The airbag 11 always keeps the area between the supporting block 10 and the supporting frame 9 closed, thereby simulating windows of different lengths. Then, the rotating structure drives the supporting shaft 13 to rotate, and the supporting shaft 13 drives the adjusting baffle to deflect at different angles, thus simulating different window opening situations and making the detection range more comprehensive.

[0025] In this embodiment, a connecting ball 17 is fixedly sleeved on the air inlet pipe 4. The connecting ball 17 is rotatably mounted on the corresponding movable door 3. A fixed rod 18 is connected to the connecting ball 17 by a ball hinge. A movable rod 19 is slidably mounted on the end of the fixed rod 18. A locking pin is provided between the fixed rod 18 and the movable rod 19 (which is a conventional technical means and therefore not shown in the figure).

[0026] In this solution, the locking pin is removed, allowing the movable rod 19 to slide relative to the fixed rod 18. At this time, the deflection connecting ball 17 can adjust the orientation of the air inlet duct 4, thereby changing the wind direction and simulating the effect of different wind directions on the glass curtain wall. When it is necessary to fix the air inlet duct 4, simply reset the locking pin to restrict the movable rod 19 from sliding relative to the fixed rod 18. The operation is simple and quick.

[0027] In this embodiment, the end of the humidity control box 8 away from the air inlet duct 4 is connected to the outside via a connecting pipe 20, which is coaxial with the air inlet duct 4. A T-shaped bracket 27 is hinged to the side wall of the humidity control box 8, and humidity pipes 21 parallel to the connecting pipe 20 are fixed at both ends of the bracket 27. A filter frame 26 is detachably connected to one of the humidity pipes 21, and a desiccant is placed inside the filter frame 26. A humidifier 22 is installed in the other humidity pipe 21 (this is a conventional technical means and therefore not described in detail). A telescopic push rod 23 for pushing the support rod to deflect is provided on the side wall of the humidity control box 8 (an electric telescopic rod is used, which is a conventional technical means and therefore not described in detail).

[0028] In this solution, a filter frame 26 with desiccant and a humidifier 22 for humidification are respectively installed in the two humidity pipes 21. When humidification or dehumidification is required, the bracket 27 is deflected by the telescopic push rod 23 so that the corresponding humidity pipe 21 is located between the air inlet pipe 4 and the connecting pipe 20. The whole operation process is simple and quick.

[0029] In this embodiment, both ends of the humidity pipe 21 are slidably fitted with annular blocks 24, and the sidewalls of the humidity pipe 21 are provided with bidirectional telescopic rods 25 (electric telescopic rods are used, which is a conventional technical means, so they are not described in detail). The ends of the bidirectional telescopic rods 25 are fixedly connected to the corresponding annular blocks 24.

[0030] The bidirectional telescopic rod 25 drives the annular block 24 to move to the connection point of the humidity pipe 21, the air inlet pipe 4, and the connecting pipe 20, thereby reducing the entry of outside air and affecting the temperature and humidity of the airflow.

[0031] In this embodiment, a rubber layer is provided on the inner wall of the annular block 24.

[0032] The sealing performance of the annular block 24 is enhanced by adding a rubber layer.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
