DETAILED DESCRIPTION

[0036] The following non-limiting examples are intended to illustrate the present application.

[0037] Example 1

[0038] Reference Figures 1-7 As shown in the figure, a roof exhaust device includes a roof structure 1, a riser pipe 2, a rainproof cap 3, a rotating shaft assembly 4, a support assembly 5, and an exhaust assembly 6.

[0039] The riser pipe 2 is arranged on the roof structure 1, the support assembly 5 is fixed in the riser pipe 2, the rotating shaft assembly 4 is arranged on the support assembly 5 and rotates, the upper end of the rotating shaft assembly 4 is connected with the rainproof cap 3, the rainproof cap 3 is arranged above the riser pipe 2, the lower end of the rotating shaft assembly 4 is connected with the exhaust assembly 6, and the exhaust assembly 6 is arranged in the riser pipe 2.

[0040] Under the action of external wind, the rainproof cap 3 rotates along the designed rotation direction, driving the rotating shaft assembly 4 to rotate on the support assembly 5, and driving the exhaust assembly 6 to rotate, so that the exhaust assembly 6 generates upward lift in the riser pipe 2, causing the gas at the lower end of the riser pipe 2 to rise and be discharged from the upper end.

[0041] The roof structure 1 includes a protective layer 101, a waterproof layer 102, a leveling layer 103, an insulation layer 104, a slope layer 105, and a structural layer 106 arranged layer by layer from top to bottom, the upper end of the riser pipe 2 extends out of the protective layer 101, and the lower end of the riser pipe 2 extends into the insulation layer 104, so that the water vapor in the insulation layer 104 is discharged to the outside, ensuring the dryness and air pressure balance inside the roof.

[0042] The riser pipe 2 is preferably a PVC round pipe, which has corrosion resistance and weather resistance. The rainproof cap 3 is a shell-shaped structure with a hemispherical profile, which covers the upper end of the riser pipe 2, and the rainproof cap 3 is provided with air holes on the side, which can rotate under the action of external wind. The designed rotation direction of the rainproof cap 3 is the direction in which the rainproof cap 3 rotates along the specified direction (clockwise or counterclockwise) under the action of wind, and the specified direction rotation can be achieved by the pressure difference generated by the arc-shaped fan blades of the cap itself.

[0043] The rotating shaft assembly 4 comprises a rotating shaft 401, an end cap 402, a clamping key section 403, a rotating ring 404, a key groove 405 and a connecting section 406. The upper end of the rotating shaft 401 is connected with the rainproof air cap 3, and specifically, the upper end of the rotating shaft 401 is connected with the rainproof air cap 3 through the end cap 402, the end cap 402 is welded or clamped on the rainproof air cap 3, and the rotating shaft 401 is welded or clamped on the end cap 402, so that the rainproof air cap 3 and the rotating shaft 401 are synchronously rotated.

[0044] The middle section of the rotating shaft 401 is the clamping key section 403, the clamping key section 403 is clamped and matched with the key groove 405 of the rotating ring 404, the clamping key section 403 and the key groove 405 are cross-shaped structures matched with each other, so that the clamping key section 403 and the key groove 405 are clamped and driven. The rotating shaft 401 is rotatably arranged on the support assembly 5 through the rotating ring 404, and the rotating ring 404 can be an integral whole rotatably arranged on the support assembly 5 or a bearing, so that the rotating shaft 401 can rotate on the support assembly 5.

[0045] The lower end of the rotating shaft 401 is connected with the exhaust assembly 6, and specifically, the lower section of the rotating shaft 401 is the connecting section 406, the connecting section 406 is connected with the exhaust assembly 6, and the connection mode is welding or tight connection, so that the rotating shaft 401 drives the exhaust assembly 6 to synchronously rotate.

[0046] The support assembly 5 comprises a sleeve 501, a support upper disc 502, a support lower disc 503, an upper support leg 504, a lower support leg 505, a pad 506 and a spring 507. The rotating rings 404 at the upper and lower ends of the rotating shaft 401 are rotatably arranged at the upper and lower ends of the sleeve 501, so that the rotating shaft 401 can rotate along the axis but cannot move along the axis.

[0047] The sleeve 501 is sleeved with the support upper disc 502 and the support lower disc 503 which can move up and down, the support upper disc 502 and the support lower disc 503 can be adjusted in position relative to the sleeve 501, and the disc body needs to be fixed after adjustment. Specifically, the upper section of the outer side of the sleeve 501 is a normal thread matched with the inner thread of the support upper disc 502, the lower section of the outer side of the sleeve 501 is a reverse thread matched with the inner thread of the support lower disc 503, so that when the sleeve 501 rotates in the normal direction, the two support discs move close to each other, and when the sleeve 501 rotates in the reverse direction, the two support discs move away from each other.

[0048] A plurality of upper support legs 504 and lower support legs 505 are uniformly arranged between the support upper disc 502 and the support lower disc 503 in the circumferential direction, the support upper disc 502 is hinged to the upper end of the upper support leg 504, the lower end of the upper support leg 504 is hinged to the upper end of the lower support leg 505 through the pad 506 (the hinging form can be that the two support legs are respectively hinged to two nodes of the pad, or the two support legs are hinged to one node of the pad), the lower end of the lower support leg 505 is hinged to the support lower disc 503, and the pad 506 is supported on the inner wall of the stand pipe 2.

[0049] Two support discs are close to each other to realize the outward support of the backing plate, so that the backing plate 506 is close to the inner wall of the stand pipe 2, because the friction force ensures that the support assembly 5 is fixed in the stand pipe 2 and does not fall. Two support discs are away from each other to realize the inward retraction of the backing plate, so that the backing plate 506 is relaxed relative to the stand pipe 2, and then the overall device can be disassembled. A spring 507 is arranged between the upper support leg 504 and the lower support leg 505, which provides a pre-tightening force for the support leg, tries to maintain the outward support state of the backing plate 506, and improves the overall stability.

[0050] Due to the adjustable support of the support disc and the support leg, the support assembly 5 can meet different forms and specifications of the stand pipe 2, and improve the versatility of the device.

[0051] The design rotation direction of the rainproof hat 3 is the same as the outward support rotation direction of the sleeve 501, that is, the positive rotation direction, so that the two support discs are close to each other to outwardly support the backing plate. When the rainproof hat 3 rotates along the design rotation direction, the sleeve 501 also has a synchronous rotation trend through the rotating shaft 401, so that the backing plate 506 also has a continuous outward support trend under the action of the sleeve 501, thereby ensuring the stability of the support.

[0052] The exhaust assembly 6 includes a center cylinder 601, exhaust vanes 602 and spiral vanes 603. The center cylinder 601 is fixedly connected with the connecting section 406 of the rotating shaft assembly 4. The upper and lower ends of the center cylinder 601 are provided with exhaust vanes 602, and the middle section of the center cylinder 601 is provided with spiral vanes 603. The exhaust vanes 602 and the spiral vanes 603 can generate lift on the gas in the stand pipe 2, realizing the effect of exhaust and moisture-proof.

[0055] Second, install the rotating shaft assembly 4 on the support assembly 5 to ensure that the rotating shaft assembly 4 rotates relative to the support assembly 5. First, install the rotating ring 404 on both ends of the sleeve 501, and then pass the rotating shaft 401 through the rotating ring 404 and connect and fix the two.

[0056] Third, connect the rotating shaft assembly 4 with the exhaust assembly 6. Insert and fix the connecting section 406 of the rotating shaft 401 into the center cylinder 601.

[0057] Fourthly, the support assembly 5 is fixed in the riser 2. The rotating sleeve 501 realizes the outward support of the backing plate 506, and the backing plate 506 is tightly supported on the inner wall of the riser 2, so as to realize the fixation of the device in the riser 2.
