[0028] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, this embodiment provides an inclined insertion and embedded adjustable air outlet device, which includes an arc-shaped air valve plate 8, a rotating shaft 2, a frame body 6, side wing plates 7 and an air outlet panel 4. The frame body 6 is arranged at the air outlet opening 3 of the supply / return air main pipe 1. Specifically, the frame body 6 is fixedly riveted to the short side of the supply / return air main pipe 1 through a flange, and the air inlet / outlet of this inclined insertion and embedded adjustable air outlet device is designed at this air outlet opening 3. Specifically, the air inlet / outlet here is a standard series air outlet riveted to the air outlet panel 4; the air outlet panel 4 is fixedly riveted to the frame body 6, and a scale hole 5 is opened on the air outlet panel 4; the arc-shaped air valve plate 8 is inclined and inserted into the supply / return air main pipe 1, and the projection of the arc-shaped air valve plate 8 on the wall of the supply / return air main pipe 1 covers the air outlet opening 3 of the supply / return air main pipe 1. One end of the arc-shaped air valve plate 8 is hinged to the frame body 6 through a rotating shaft 2, and a driving component for driving the arc-shaped air valve plate 8 to rotate around the rotating shaft 2 is connected to the other end of the arc-shaped air valve plate 8. The driving component penetrates through the scale hole 5. There are two side wing plates 7, which are located in the supply / return air main pipe 1 and are fixed to the frame body 6 through bolts. The two side wing plates 7 are respectively located on both sides of the arc-shaped air valve plate 8 and enclose with the arc-shaped air valve plate 8. The opening direction between the arc-shaped air valve plate 8 and the supply / return air main pipe 1 is arranged towards the air flow direction in the supply / return air main pipe 1. In this embodiment, the arc-shaped air valve plate 8 is driven to rotate around the rotating shaft 2 through the driving component, so as to adjust the area of the opening between the arc-shaped air valve plate 8 and the supply / return air main pipe 1. Corresponding to the air inlet / outlet of this inclined insertion and embedded adjustable air outlet device at the air outlet opening 3, the opening between the arc-shaped air valve plate 8 and the supply / return air main pipe 1 serves as the air outlet / inlet of this inclined insertion and embedded adjustable air outlet device, so as to realize the adjustment of the air volume of the supply / return air outlet of the inclined insertion and embedded adjustable air outlet device; at the same time, during the supply / return air process of this inclined insertion and embedded adjustable air outlet device, due to the guiding effect of the arc-shaped air valve plate 8 on the air flow direction at its air outlet / inlet, the air flow direction at the air inlet / outlet of the air outlet device is basically the same as the air flow direction in the supply / return air main pipe 1, avoiding the impact of the air flow at the air inlet / outlet of the air outlet device on the air flow in the supply / return air main pipe 1, reducing the resistance of the supply / return air system, and reducing the system operation energy consumption. This inclined insertion and embedded adjustable air outlet device provided by this embodiment can be directly installed by opening a hole and embedding it on the supply / return air main pipe 1, which is convenient for construction. Especially for finished composite air ducts, the air outlet can be pre-installed in the factory or directly installed by opening a hole on site, which is convenient and fast.

[0029] Among them, the specification size of this inclined insertion and embedded adjustable air outlet device is consistent with the standard series size of the air outlet.

[0030] In a detailed implementation, the arc-shaped air valve plate 8 includes a straight plate section and an arc-shaped section, and can be made of a rectangular plate by arc-bending. The end of the straight plate section is hinged to the frame 6 through the rotating shaft 2, and the end of the arc-shaped section is connected to the driving component. Optimally, the maximum angle between the arc-shaped air valve plate 8 and the air supply / exhaust main pipe 1 is 45°, that is, when the obliquely inserted embedded adjustable air outlet device is in a fully open state, the straight plate section of the arc-shaped air valve plate 8 and the short side of the air supply / exhaust main pipe 1 form an angle of 45°.

[0031] Furthermore, a gap is left between the side wing plate 7 and the arc-shaped air valve plate 8, and the gap does not exceed 2 mm, so as to minimize the air leakage through the gap while ensuring the smooth rotation of the arc-shaped air valve plate 8.

[0032] For a specific implementation of the side wing plate 7 structure, in conjunction with the structural design of the arc-shaped air valve plate 8, the side wing plate 7 includes an inclined section and a horizontal section, the inclination angle of the inclined section is the same as the maximum angle formed by the arc-shaped air valve plate 8 and the supply / exhaust air pipe 1, that is, the inclination angle of the inclined section is designed to be 45°, and the distance between the horizontal section and the wall of the supply / exhaust air pipe 1 is not less than the distance between the top of the arc-shaped air valve plate 8 and the wall of the supply / exhaust air pipe 1, to ensure that the arc-shaped air valve plate 8 can be enclosed by the side wing plates 7 on both sides during rotation.

[0033] Optimally, a connecting plate 9 is connected between the tops of the side wing plates 7 on both sides of the arc-shaped air valve plate 8, so as to strengthen the structural stability of the side wing plates 7 fixed on both sides of the arc-shaped air valve plate 8. At the same time, it is designed that when the obliquely inserted and embedded adjustable air outlet device is in a fully open state, the lower surface of the connecting plate 9 can fit with the top of the arc-shaped air valve plate 8.

[0034] Furthermore, the materials of the arc-shaped air valve plate 8, the side wing plate 7 and the air outlet panel 4 can be adjusted according to actual needs, and galvanized steel plates, stainless steel plates (304, the thickness is determined according to the component size) and other materials that meet the fire resistance requirements of the subway can be used.

[0035] In this embodiment, a specific implementation of the driving component is as follows: Figure 1As shown, the driving component includes an adjusting scale 11 and a fixed side ear 10 welded to the arc-shaped air valve plate 8. One end of the adjusting scale 11 is hinged to the fixed side ear 10, and the other end of the adjusting scale 11 passes through the scale hole 5 and extends outside the supply / ventilation main pipe 1. The adjusting scale 11 realizes a pushing and pulling movement inward or outward along the scale hole 5 on the air outlet panel 4. At the same time, the end of the adjusting scale 11 can be hinged and rotated at any angle through the fixed side ear 10 on the arc-shaped air valve plate 8, so as to drive the arc-shaped air valve plate 8 to rotate around the rotating shaft 2. Further, the adjusting scale 11 is provided with adjusting scales, which can accurately adjust the rotation angle of the arc-shaped air valve plate 8, and further realize the accurate adjustment of the air volume of the supply / ventilation opening, effectively solving the problems of uniform air supply / ventilation (smoke exhaust) over a long longitudinal distance and multiple air outlets in the prior art.

[0036] Optimally, as Figure 2 and Figure 4 shown, the adjusting scale 11 is further provided with an adjusting chute 12. At the same time, a positioning hole 14 for corresponding fixation with the adjusting chute 12 is welded on the air outlet panel 4. When the adjusting scale 11 pushes and pulls the arc-shaped air valve plate 8 to rotate and the air passing area of its air inlet / outlet is adjusted in place, the adjusting scale 11 is locked on the positioning hole 14 on the air outlet panel 4 through the adjusting chute 12 by a bolt 13, so as to fix the arc-shaped air valve plate 8. Specifically, the adjusting scale 11 is made of stainless steel plate material to enhance its rigidity, and the thickness of the adjusting scale 11 is 1.5 - 2 mm, which is specifically determined according to the component size.

[0037] In summary, the oblique insertion and installation type adjustable air outlet device provided by the present invention controls the air passing area of the air inlet / outlet of the supply / ventilation main pipe through the adjustment of the arc-shaped air valve plate, realizes the adjustment of the air volume of the supply / ventilation opening, is convenient and adjustable. At the same time, due to the guiding action of the arc-shaped air valve plate on the air flow direction at the air inlet / outlet of the oblique insertion and installation type adjustable air outlet device, the air flow direction at the air inlet / outlet is basically the same as the air flow direction in the supply / ventilation main pipe, avoiding the impact of the air flow at the air inlet / outlet of the air outlet device on the air flow in the supply / ventilation main pipe, reducing the resistance of the supply / ventilation system, and reducing the system operation energy consumption.

[0038] The above examples are only illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. Any design identical or similar to the present invention falls within the protection scope of the present invention.
