[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0033] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", "fourth", "fifth", and "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figures 1 to 3As shown in the figure, an anti-wind pressure detection device for a glass curtain wall proposed by the present invention includes a detection box 1. A glass curtain wall 2 is arranged in the detection box 1. The glass curtain wall 2 includes an installation frame 21, and six groups of glass plates 22 are installed on the installation frame 21 to simulate the actual use environment. One side of the detection box 1 is open, and an air inlet pipe 11 is installed on the side of the detection box 1 away from the opening, facilitating blowing high-speed gas into the detection box 1 through the air inlet pipe 11 to conduct anti-wind pressure detection on the glass curtain wall 2.

[0037] Specifically, the above detection device includes a positioning mechanism 3 installed in the detection box 1. The positioning mechanism 3 is used for clamping and positioning the glass curtain wall 2. The positioning mechanism 3 includes a fixed block 31 fixedly connected to the inner wall of the detection box 1, and the position of the fixed block 31 is fixed. A moving block 32 is arranged above the fixed block 31. The glass curtain wall 2 is installed between the fixed block 31 and the moving block 32. The fixed block 31 and the moving block 32 are symmetrically arranged on both sides of the glass curtain wall 2. The cross-sections of the fixed block 31 and the moving block 32 are both "U"-shaped structures. The moving block 32 is used to cooperate with the fixed block 31 to clamp the glass curtain wall 2 to achieve rapid fixation of the glass curtain wall 2. A bottom block 33 is fixedly connected to the bottom of the fixed block 31, and multiple groups of pulleys 34 are rotatably connected to the top of the bottom block 33. The pulleys 34 are in contact with the bottom of the glass curtain wall 2, so that after the glass curtain wall 2 is placed on the fixed block 31, it is convenient to move the glass curtain wall 2 and move the glass curtain wall 2 to the middle position. A push rod motor 35 is installed on the top of the detection box 1. The output end of the push rod motor 35 penetrates the detection box 1 and is fixedly connected to the moving block 32. After the push rod motor 35 is started, it drives the moving block 32 to move. The moving block 32 squeezes the glass curtain wall 2 to achieve fixation of the glass curtain wall 2. At the same time, anti-slip strips are installed on the inner wall of the moving block 32 to increase the firmness of the glass curtain wall 2 after fixation. Two groups of limiting rods 36 are fixedly connected to the top of the moving block 32, and the limiting rods 36 move synchronously with the moving block 32. A limiting sleeve 37 is slidably connected to the limiting rod 36. The limiting sleeve 37 is installed on the top of the detection box 1. The moving block 32 moves smoothly under the limiting action of the limiting rod 36 and the limiting sleeve 37.

[0038] Furthermore, the above-mentioned detection device also includes a fixed plate 4 arranged on the side of the glass curtain wall 2 away from the air inlet duct 11, the fixed plate 4 is fixedly connected to the inner wall of the detection box 1, and the position of the fixed plate 4 is fixed. Three groups of movable plates 41 are arranged above the fixed plate 4, and a top plate 42 is arranged above the movable plate 41. The fixed plate 4, the movable plate 41 and the top plate 42 are arranged equidistantly, and four groups of mounting blocks 43 are slidably connected to the three groups of movable plates 41, and the four groups of mounting blocks 43 are arranged equidistantly. The displacement meter 5 is installed on the side of the mounting block 43 close to the glass curtain wall 2, so that the multiple groups of displacement meters 5 are equidistantly arranged in the horizontal and vertical directions, which is convenient for synchronous adjustment, so as to align with the mounting frames 21 of different sizes. The measuring end of the displacement meter 5 can adjust the position with the glass curtain wall 2, so as to sense the deformation amount when the glass curtain wall 2 is deformed. This is a prior art and will not be described in detail here. The displacement meter 5 contacts the mounting frame 21 to sense the deformation of the glass curtain wall 2 to detect wind pressure resistance. When the glass curtain wall 2 is deformed, the displacement meter 5 senses the displacement distance, thereby determining the degree of bending of the glass curtain wall 2, thereby achieving the purpose of detecting the ability to resist wind pressure.

[0039] It is worth mentioning that Figure 4 and Figure 5 As shown, the above-mentioned detection device includes a lateral synchronous adjustment mechanism 6 arranged in the detection box 1, and the lateral synchronous adjustment mechanism 6 is used to synchronously adjust the lateral spacing between multiple groups of displacement meters 5. The lateral synchronous adjustment mechanism 6 includes three groups of first connecting frames, and the first connecting frame includes a first connecting plate 61, a second connecting plate 62, a third connecting plate 63 and a fourth connecting plate 64. The first connecting plate 61, the second connecting plate 62, the third connecting plate 63 and the fourth connecting plate 64 are respectively provided with two groups. One end of the two groups of first connecting plates 61 are rotatably connected to the two groups of second connecting plates 62 respectively, one end of the two groups of second connecting plates 62 away from the first connecting plate 61 are rotatably connected to the two groups of third connecting plates 63 respectively, one end of the two groups of third connecting plates 63 away from the second connecting plate 62 are rotatably connected to the two groups of fourth connecting plates 64 respectively, the first connecting plate 61, the second connecting plate 62, the third connecting plate 63 and the fourth connecting plate 64 are rotatably connected in sequence to the side of the four groups of mounting blocks 43 away from the displacement meter 5, so that the mounting blocks 43 move synchronously under the action of the first connecting frame, and the spacing between the four groups of mounting blocks 43 on the same group of moving plates 41 remains equal. The second connecting plate 62 and the third connecting plate 63 are rotatably connected with a sliding column 65, and a vertically arranged positioning plate 66 is installed on the inner wall of the detection box 1. The four groups of mounting blocks 43 are symmetrically arranged with the center of the positioning plate 66. The sliding column 65 is slidably connected in the positioning plate 66, so that one end of the two groups of second connecting plates 62 and the two groups of third connecting plates 63 can only move up and down, thereby ensuring that the middle position of the four groups of displacement meters 5 is determined, so that the displacement meters 5 correspond to the positions of the glass curtain wall 2 after the glass curtain wall 2 is positioned in the middle position.

[0040] For further information, see Figure 6The above detection device includes a longitudinal synchronous adjustment mechanism 7 arranged in the detection box 1, and the longitudinal synchronous adjustment mechanism 7 is used to synchronously adjust the longitudinal spacing between multiple groups of displacement meters 5. The longitudinal synchronous adjustment mechanism 7 includes two groups of second connecting frames, and the second connecting frame includes five groups of fifth connecting plates 71 arranged in parallel. The five groups of fifth connecting plates 71 are respectively rotatably connected to the sides of the fixed plate 4, the movable plate 41 and the top plate 42, and the rotating shaft of the fifth connecting plate 71 is also rotatably connected to the sixth connecting plate 72. Multiple groups of sixth connecting plates 72 are arranged in parallel, and the fifth connecting plates 71 and the sixth connecting plates 72 are arranged crosswise. The adjacent fifth connecting plates 71 and the sixth connecting plates 72 are rotatably connected, so that the fixed plate 4, the movable plate 41 and the top plate 42 move synchronously, and the effective spacing of the second connecting frame is always kept equal. Multiple groups of driving plates 73 are installed on the side of the moving block 32, and the driving plates 73 are fixedly connected to the top plate 42, and are used to drive the top plate 42 to move through the driving plates 73 when the moving block 32 moves, so as to synchronously adjust the positions of the multiple groups of movable plates 41, so as to achieve the consistency of the upper and lower spacing of the multiple groups of displacement meters 5.

[0041] Also, see Figure 3 , Figure 5 and Figure 7The detection device also includes a synchronization component 8 for adjusting the lateral synchronization adjustment mechanism 6 to adapt it to the width of the glass curtain wall 2. The synchronization component 8 includes two sets of first slide rails 801 fixedly connected to the fixed block 31 on the side close to the displacement meter 5. The first slide rail 801 is slidably connected with a first slider 802, and the first slider 802 moves smoothly. The first slider 802 is fixedly connected with a first sleeve 803, and the first sleeve 803 moves smoothly under the limiting action of the first slide rail 801 and the first slider 802. The first sleeve 803 is slidably connected with a first slide plate 804, and the first slide plate 804 has edges and corners and can slide smoothly in the first slide rail 801. The top of the first slide plate 804 is fixedly connected with a second slide block 805, and the second slide rail 806 is slidably connected in the second slide block 805. The second slide rail 806 is fixedly connected to the side of the moving block 32. The first slide plate 804 moves smoothly under the limiting action of the second slide block 805 and the second slide rail 806. At the same time, even if the moving block 32 moves to the position farthest from the fixed block 31, the first slide plate 804 is still inserted in the first sleeve 803. A clamping plate 807 is installed on the side of the first sleeve 803 close to the glass curtain wall 2. The clamping plate 807 is set in an L shape. Two sets of clamping plates 807 are clamped on both sides of the glass curtain wall 2 to achieve positioning. The synchronization assembly 8 also includes two groups of slide bars 808 arranged on the side of the first sleeve 803 away from the glass curtain wall 2. The two groups of slide bars 808 are respectively fixedly connected to the outer sides of the upper and lower groups of mounting blocks 43. A sliding sleeve 809 is slidably connected between the two groups of slide bars 808. A fixed rod 810 is fixedly connected to one side of the sliding sleeve 809. The fixed rod 810 is fixedly connected to the first sleeve 803 and is used to drive the first sleeve 803 to move synchronously when the mounting block 43 moves. A second sleeve 811 is also installed on the top of the upper group of mounting blocks 43 of the fixed slide bar 808. A second slide plate 812 is slidably connected in the second sleeve 811. The top of the second slide plate 812 is fixedly connected to the uppermost group of mounting blocks 43, so that the upper two groups of mounting blocks 43 can move synchronously horizontally without hindering their synchronous longitudinal movement.

[0042] Finally, both sides of the test box 1 are hinged with air outlet doors 12, and two groups of air outlet doors 12 are symmetrically arranged on both sides of the glass curtain wall 2. Two groups of support rods 9 are connected between the air outlet doors 12 and the two ends of the second connecting frame, and the two ends of the support rods 9 are universally connected to the air outlet doors 12 and the second connecting frame respectively. Therefore, when the fifth connecting plate 71 and the sixth connecting plate 72 are deflected, the air outlet doors 12 are driven to deflect through the support rods 9, and the larger the size of the glass curtain wall 2, the larger the opening angle of the air outlet doors 12, which is convenient for increasing the air outlet volume and ensuring that the glass curtain wall 2 is subjected to the specified wind pressure. At the same time, when the air flows through the inner side of the air outlet door 12, the wind speed inside the air outlet door 12 is greater than the wind speed outside the air outlet door 12, and the resulting pressure difference will close the air outlet door 12 inward, but because the air outlet door 12 is connected to the second connecting frame through the support rods 9, the second connecting frame needs to drive the moving block 32 to move when deformed. Since the position of the moving block 32 is fixed, the second connecting frame will not be deformed, so that the support rod 9 effectively supports the air outlet door 12 and prevents the air outlet door 12 from closing under the pressure difference caused by the flow rate, thereby ensuring the size of the air outlet and ensuring that the wind pressure on the glass curtain wall 2 is controllable.

[0043] In this embodiment, when installing, the push rod motor 35 is started to contract and drive the moving block 32 to move upward, the glass curtain wall 2 is placed on the fixed block 31, and the card plate 807 is pushed to make it close to the glass curtain wall 2 and push the glass curtain wall 2 to move in the fixed block 31. At this time, through the setting of the horizontal synchronous adjustment mechanism 6, the two groups of card plates 807 will move synchronously to the middle position until the two groups of card plates 807 are in contact with the side of the glass curtain wall 2, and the horizontal synchronous adjustment mechanism 6 will also synchronously adjust the vertical spacing of the multiple groups of displacement meters 5. At this time, the push rod motor 35 is started to drive the moving block 32 to press on the top of the glass curtain wall 2 to fix the position of the glass curtain wall 2. At the same time, when the moving block 32 moves, the top plate 42 is driven to move through the driving plate 73, and at the same time, under the action of the longitudinal synchronous adjustment mechanism 7, the upper and lower spacings of the multiple groups of displacement meters 5 are equal. Therefore, after the glass curtain wall 2 is installed, the multiple groups of displacement meters 5 can accurately point to the installation frame 21, so that after high-speed gas is introduced into the air inlet pipe 11, the gas directly blows the glass curtain wall 2, causing the glass curtain wall 2 to bend. At the same time, the displacement meters 5 sense the displacement of different positions of the glass curtain wall 2, thereby knowing the degree of bending of the glass curtain wall 2, which is convenient for testing the wind pressure resistance of the glass curtain wall 2.

[0044] When installing a larger glass curtain wall 2, air passes through the edge of the glass curtain wall 2. Since the glass curtain wall 2 is larger, the gap between the glass curtain wall 2 and the detection box 1 is relatively small, which will increase the wind pressure on the glass curtain wall 2, making it difficult to control the wind pressure. By setting the support rod 9, when the position of the displacement meter 5 is adjusted, the air outlet door 12 is simultaneously driven to open, increasing the gap for air flow and ensuring the controllability of the wind pressure.

[0045] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
