Description

Technical Field

[0001] The invention belongs to the technical field of building simulation, and in particular relates to an extreme cold and drought environment simulation box. Background Art

[0002] Glass curtain walls have the advantages of beauty, heat insulation, and sound insulation, and are widely used in modern buildings. In the northwest of my country, the weather outside is cold and dry, and air conditioners, humidifiers and other equipment are often used indoors for heating and humidification, which makes the temperature and humidity inside and outside the glass curtain wall different. The two sides of the glass curtain wall are easily cracked due to the influence of thermal expansion and contraction, which poses certain safety hazards. Therefore, an environmental simulation box is needed to simulate the safety performance of the glass curtain wall when the temperature and humidity on both sides are different in the extremely cold and dry environment of the northwest. Summary of the invention

[0003] In view of this, the present invention discloses an extreme cold and drought environment simulation box, which aims to simulate the extreme cold and drought environment in the northwest to detect the safety performance of glass curtain walls.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A simulation box for an extremely cold and arid environment comprises a hollow box body, a through slot is provided on one side of the middle part of the box body, a slide slot connected to the through slot is provided on the bottom of the box body, a mounting frame for mounting a glass curtain wall is slidably connected in the slide slot, a power structure for driving the mounting frame to move is provided on the mounting frame, and a rubber layer for blocking the slide slot and the through slot is provided on the surrounding side of the mounting frame; movable doors are hinged at both ends of the box body, an air inlet duct connected to the outside is provided on the movable doors, a fan is provided at the port of the air inlet duct facing the middle part of the box body, a humidity control box for controlling the humidity of the gas is provided at the other end of the air inlet duct, a heater and a cooler are provided between the fan and the humidity control box; a detector for detecting the glass curtain wall is provided on the mounting frame.

[0006] In this solution, the glass curtain wall to be tested is installed on the installation frame, and then the installation frame is driven by the power structure to slide the installation frame and the glass curtain wall into the box. The fan in the air inlet duct blows air to the glass curtain wall at the same time; at the same time, the humidity control box corresponding to the air inlet duct on one side reduces the humidity of the air flow, and reduces the air flow temperature through the corresponding cooler, while the humidity control box corresponding to the air inlet duct on the other side increases the humidity of the air flow, and reduces the air flow temperature through the corresponding heater, so that one side of the glass curtain wall is subjected to cold and dry air flow, and the other side of the glass curtain wall is subjected to warm and humid air flow, thereby simulating the use environment of the glass curtain wall to test the safety performance of the glass curtain wall. In addition, the temperature and humidity of the environment on both sides of the glass curtain wall can be adjusted according to seasonal changes, so as to more comprehensively test the performance of the glass curtain wall.

[0007] Furthermore, an adjustment slot is provided on the mounting frame, a support frame is arranged in the adjustment slot, and a rotating shaft is rotatably connected between both ends of the support frame and the adjustment slot; an adjustment baffle with adjustable angle is arranged on the support frame.

[0008] In this solution, by changing the angle of the adjusting baffle, the airflows on both sides of the glass curtain wall are made to converge, thereby simulating the situation where the internal and external airflows converge when the window is opened, which is more in line with the actual use environment and can more comprehensively test the performance of the glass curtain wall. In addition, by rotating the support frame, the up and down orientation of the window can be simulated, and changing the different angles of the adjusting baffle can simulate different opening angles of the window, making the simulated data more comprehensive.

[0009] Furthermore, a horizontally arranged support block is provided in the support frame, an airbag is provided between one end of the support block and the support frame, guide rods with a telescopic structure are provided on both sides of the airbag, and both ends of the guide rods are respectively connected to the support frame and the support block; the other end of the support block is rotatably connected to a horizontally arranged support shaft, and a rotating structure for driving the support shaft to rotate is provided on the support block; the adjustment baffle includes a fixed plate body fixed on the support shaft, an adjustment groove is provided at the end of the fixed plate body, an adjustment plate body is slidably connected in the adjustment groove, and a push rod is provided between the adjustment plate body and the fixed plate body.

[0010] In this solution, when it is necessary to isolate the airflow on both sides, the adjustment plate is kept against the support frame, and the airbag is inflated. The airbag, fixed plate, and adjustment plate are used to close the support frame, thereby isolating the airflow on both sides of the glass curtain wall. When it is necessary to simulate window opening, the push rod drives the adjustment plate to slide relative to the fixed plate through the extension and contraction of the guide rod, ensuring that the adjustment plate and the support frame are against each other, while the airbag always keeps the area between the closed support block and the support frame, so as to simulate windows of different lengths; then the support shaft is driven to rotate by the rotating structure, and the support shaft drives the adjustment baffle to deflect at different angles, so as to simulate different window opening conditions, making the detection range more comprehensive.

[0011] Furthermore, a connecting ball is fixedly mounted on the air inlet duct, and the connecting ball is rotatably arranged on the corresponding movable door. A fixed rod is connected to the spherical hinge on the rotating ball, and a movable rod is coaxially slidably arranged on the end of the fixed rod, and a locking pin is arranged between the fixed rod and the movable rod.

[0012] In this solution, the locking pin is removed to allow the movable rod to slide relative to the fixed rod. At this time, by deflecting the connecting ball, the direction of the air inlet duct can be adjusted, thereby changing the wind direction, thereby simulating the impact of glass curtain walls with different wind directions. When the air inlet duct needs to be fixed, it is only necessary to reset the locking pin to limit the sliding of the movable rod relative to the fixed rod. The operation is simple and quick.

[0013] Furthermore, a connecting pipe is provided at one end of the humidity control box away from the air inlet pipe and connected to the outside, and the connecting pipe is coaxial with the air inlet pipe; a T-shaped bracket is hinged on the side wall of the humidity control box, and humidity pipes parallel to the connecting pipe are fixed at both ends of the bracket, one of the humidity pipes is detachably connected to a filter frame, a desiccant is placed in the filter frame, and a humidifier is provided 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.

[0014] In this solution, a filter frame with a desiccant and a humidifier for humidification are respectively provided in the two humidity pipelines. When humidification or dehumidification is required, the bracket is pushed to deflect by the telescopic push rod so that the corresponding humidity pipeline is located between the air inlet pipeline and the connecting pipeline. The whole operation process is simple and quick.

[0015] Furthermore, annular blocks are slidably sleeved at both ends of the humidity pipeline, and bidirectional telescopic rods are arranged on the side walls of the humidity pipeline, and the ends of the bidirectional telescopic rods are fixedly connected to the corresponding annular blocks.

[0016] Furthermore, a rubber layer is provided on the inner wall of each annular block.

[0017] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] like Figures 1 to 4 As shown:

[0025] A simulation box for an extremely cold and arid environment comprises a hollow box body 1, a through groove is provided on one side of the middle part of the box body 1, a slide groove connected to the through groove is provided on the bottom of the box body 1, a mounting frame 2 for mounting a glass curtain wall is slidably connected in the slide groove, a power structure for driving its movement is provided on the mounting frame 2 (driven by a motor, which belongs to conventional technical means, so it is not elaborated in detail), and a rubber layer for blocking the slide groove and the through groove is provided on the surrounding side of the mounting frame 2; movable doors 3 are hinged at both ends of the box body 1, and an air inlet duct 4 connected to the outside is provided on the movable door 3, a fan 5 is provided at the port of the air inlet duct 4 facing the middle part of the box body 1, a humidity control box 8 for controlling the humidity of the gas is provided at the other end of the air inlet duct 4, and a heater 6 and a cooler 7 are provided between the fan 5 and the humidity control frame; a detector for detecting the glass curtain wall is provided on the mounting frame 2.

[0026] In this solution, the glass curtain wall to be tested is installed on the installation frame 2, and then the installation frame 2 is driven by the power structure, so that the installation frame 2 and the glass curtain wall slide into the box 1. The fan 5 in the air inlet duct 4 blows air to the glass curtain wall at the same time; at the same time, the humidity control box 8 corresponding to the air inlet duct 4 on one side reduces the humidity of the airflow, and reduces the airflow temperature through the corresponding cooler 7, and the humidity control box 8 corresponding to the air inlet duct 4 on the other side increases the humidity of the airflow, and reduces the airflow temperature through the corresponding heater 6, so that one side of the glass curtain wall is subjected to cold and dry airflow, and the other side of the glass curtain wall is subjected to warm and humid airflow, thereby simulating the use environment of the glass curtain wall, so as to detect the safety performance of the glass curtain wall. In addition, the temperature and humidity of the environment on both sides of the glass curtain wall can be adjusted according to seasonal changes, so as to more comprehensively detect the performance of the glass curtain wall.

[0027] In this embodiment, an adjustment slot is provided on the mounting frame 2, a support frame 9 is provided in the adjustment slot, and a rotating shaft is rotatably connected between both ends of the support frame 9 and the adjustment slot; an angle-adjustable adjustment baffle is provided on the support frame 9.

[0028] In this solution, by changing the angle of the adjusting baffle, the airflows on both sides of the glass curtain wall are converged, thereby simulating the situation where the internal and external airflows converge when the window is opened, which is more in line with the actual use environment and can more comprehensively test the performance of the glass curtain wall; in addition, by rotating the support frame 9, the up and down orientation of the window can be simulated, and changing the different angles of the adjusting baffle can simulate different opening angles of the window, thereby making the simulated data more comprehensive.

[0029] In this embodiment, a support block 10 is horizontally arranged in the support frame 9, an airbag 11 is arranged between one end of the support block 10 and the support frame 9, and guide rods 12 of a telescopic structure are arranged on both sides of the airbag 11 (electric telescopic rods are adopted, which are conventional technical means, so they are not elaborated in detail), and 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, and a rotating structure for driving the support shaft 13 to rotate is arranged on the support block 10 (a motor is adopted, which is a conventional technical means, so it is not elaborated in detail); the adjusting baffle includes a fixed plate body 14 fixed on the support shaft 13, an adjusting groove is opened at the end of the fixed plate body 14, and an adjusting plate body 15 is slidably connected in the adjusting groove, and a push rod 16 is arranged between the adjusting plate body 15 and the fixed plate body 14 (an electric telescopic rod is adopted, which is a conventional technical means, so it is not elaborated in detail).

[0030] In this solution, when it is necessary to isolate the airflow on both sides, the adjusting plate 15 is kept against the support frame 9, and the airbag 11 is inflated, and the support frame 9 is closed by the airbag 11, the fixed plate 14, and the adjusting plate 15, thereby isolating the airflow on both sides of the glass curtain wall. When it is necessary to simulate window opening, the push rod 16 drives the adjusting plate 15 to slide correspondingly relative to the fixed plate 14 through the extension and contraction of the guide rod 12, ensuring that the adjusting plate 15 is against the support frame 9, and the airbag 11 always keeps the area between the closed support block 10 and the support frame 9, so as to simulate windows of different lengths; then the support shaft 13 is driven to rotate by the rotating structure, and the support shaft 13 drives the adjusting baffle to deflect at different angles, so as to simulate different window opening conditions, making the detection range more comprehensive.

[0031] In this embodiment, a connecting ball 17 is fixedly mounted on the air inlet duct 4, and the connecting ball 17 is rotatably arranged on the corresponding movable door 3. A fixed rod 18 is connected to the ball hinge on the rotating ball, and a movable rod 19 is coaxially slidably arranged at the end of the fixed rod 18. A locking pin is arranged between the fixed rod 18 and the movable rod 19 (which is a conventional technical means and is not drawn in the figure).

[0032] In this solution, the locking pin is removed to allow the movable rod 19 to slide relative to the fixed rod 18. At this time, by deflecting the connecting ball 17, the direction of the air inlet duct 4 can be adjusted, thereby changing the wind direction, thereby simulating the influence of glass curtain walls with different wind directions; when the air inlet duct 4 needs to be fixed, it is only necessary to reset the locking pin to limit the sliding of the movable rod 19 relative to the fixed rod 18. The operation is simple and quick.

[0033] In the present embodiment, a connecting pipe 20 is provided at one end of the humidity control box 8 away from the air inlet pipe 4 and connected to the outside, and the connecting pipe 20 is coaxial with the air inlet pipe 4; a T-shaped bracket 27 is hinged on 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, one of the humidity pipes 21 is detachably connected to a filter frame 26, a desiccant is placed in the filter frame 26, and a humidifier 22 is provided in the other humidity pipe 21 (it is a conventional technical means, so it is not elaborated 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, so it is not elaborated in detail).

[0034] In this solution, a filter frame 26 with a desiccant and a humidifier 22 for humidification are respectively provided in the two humidity pipelines 21. When humidification or dehumidification is required, the bracket 27 is pushed to deflect by the telescopic push rod 23 so that the corresponding humidity pipeline 21 is located between the air inlet pipeline 4 and the connecting pipeline 20. The whole operation process is simple and quick.

[0035] In this embodiment, annular blocks 24 are slidably sleeved at both ends of the humidity pipeline 21, and bidirectional telescopic rods 25 are provided on the side walls of the humidity pipeline 21 (electric telescopic rods are used, which are conventional technical means and are not elaborated in detail), and the ends of the bidirectional telescopic rods 25 are fixedly connected to the corresponding annular blocks 24.

[0036] The annular block 24 is driven to move by the bidirectional telescopic rod 25 to move to the connection between the humidity pipeline 21, the air inlet pipeline 4 and the connecting pipeline 20, thereby reducing the entry of outside air, thereby affecting the temperature and humidity of the airflow.

[0037] In this embodiment, a rubber layer is provided on the inner wall of the annular block 24 .

[0038] By providing the rubber layer, the sealing performance of the annular block 24 is enhanced.
