Description

Technical Field

[0001] The present application belongs to the technical field of exhaust and moisture-proofing of building structures, and specifically relates to a roof exhaust device and an installation method thereof. Background Art

[0002] The roof exhaust system is a form of moisture-proof exhaust for the roof. It sets exhaust channels that run vertically and horizontally in the insulation layer of the roof structure. The exhaust channels are connected to exhaust risers that extend out of the roof, so that the gas in the insulation layer can be discharged in time, effectively preventing the roof from cracking and damage due to water freezing and gas pressure, and extending the service life of the roof.

[0003] At present, exhaust risers come in a variety of forms and specifications. In order to adapt to the specific needs, exhaust devices need to be adaptively adjusted or designed for each exhaust riser. That is, the versatility of current exhaust devices is poor and they cannot be universally used in a variety of forms and specifications, which invisibly increases the cost of design and production and is not conducive to the promotion and application of roof exhaust systems. Summary of the Invention

[0004] The purpose of this application is to provide a roof exhaust device and an installation method thereof, which solves the problem of poor versatility of existing exhaust devices.

[0005] The purpose of this application is achieved through the following technical solutions:

[0007] Furthermore, under the action of external wind, the rainproof hood rotates along the designed rotation direction, driving the rotating shaft assembly to rotate on the supporting assembly, and the rotating shaft assembly drives the exhaust assembly to rotate. The rotation of the exhaust assembly generates an upward lift in the vertical pipe, causing the air at the lower end of the vertical pipe to rise and be discharged from the upper end.

[0008] Furthermore, the upper end of the vertical pipe extends out of the roof structure, the lower end of the vertical pipe extends into the insulation layer of the roof structure, and the side of the rainproof wind cap is provided with wind holes.

[0010] Furthermore, the rotating shaft assembly includes a rotating shaft and a rotating ring, the upper end of the rotating shaft is connected to the rainproof wind cap, the lower end of the rotating shaft is connected to the exhaust assembly, and the rotating shaft is rotatably arranged on the supporting assembly through the rotating ring.

[0011] Furthermore, the upper end of the rotating shaft is connected to the rainproof wind cap through the end cap, the middle section of the rotating shaft is the key section, the key section is engaged with the key slot of the rotating ring, and the lower section of the rotating shaft is the connecting section, which is connected to the exhaust assembly.

[0012] Furthermore, the support assembly includes a sleeve, a support upper plate, a support lower plate, an upper support leg, a lower support leg and a pad. The rotating shaft assembly is rotatably arranged on the sleeve. The sleeve is provided with a support upper plate and a support lower plate that can move up and down. The support upper plate is hinged to the upper end of the upper support leg, the lower end of the upper support leg is hinged to the upper end of the lower support leg through the pad, the lower end of the lower support leg is hinged to the support lower plate, and the pad is supported on the inner wall of the riser.

[0013] Furthermore, the upper section of the positive thread on the outer side of the sleeve cooperates with the internal thread supporting the upper plate, and the lower section of the reverse thread on the outer side of the sleeve cooperates with the internal thread supporting the lower plate.

[0014] Furthermore, the design rotation direction of the rainproof hood is the same as the outer support rotation direction of the sleeve.

[0015] Furthermore, a spring is provided between the upper support leg and the lower support leg.

[0016] Furthermore, the exhaust assembly includes a central tube, exhaust fan blades and spiral blades. The central tube is connected to the rotating shaft assembly. The upper and lower ends of the central tube are provided with exhaust fan blades, and the middle section of the central tube is provided with spiral blades.

[0017] A method for installing a roof exhaust device, for the above-mentioned roof exhaust device, comprises the following steps:

[0018] The first step is to install the riser to the roof structure;

[0019] The second step is to install the shaft assembly onto the support assembly to ensure that the shaft assembly rotates relative to the support assembly;

[0020] The third step is to connect the shaft assembly to the exhaust assembly;

[0025] (2) Keep the designed rotation direction of the rainproof hood the same as the outer support rotation direction of the sleeve. Then, driven by the rotation of the rainproof hood, the sleeve of the support assembly has a tendency to be tightened outward, thereby ensuring good stability of the support assembly.

[0026] (3) An exhaust assembly is arranged at the lower end of the riser to provide upward lift for the air in the riser, optimize the circulation effect inside the riser, and improve the exhaust moisture-proof effect.

DETAILED DESCRIPTION

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

[0037] Example 1

[0038] refer to Figures 1 to 7 As shown, a roof exhaust device includes a roof structure 1, a vertical pipe 2, a rainproof wind cap 3, a rotating shaft assembly 4, a support assembly 5 and an exhaust assembly 6.

[0039] The riser 2 is arranged on the roof structure 1, and a support assembly 5 is fixed inside the riser 2. A rotating shaft assembly 4 is provided on the support assembly 5. The upper end of the shaft assembly 4 is connected to the rainproof wind cap 3, and the rainproof wind cap 3 is arranged above the riser 2. The lower end of the shaft assembly 4 is connected to the exhaust assembly 6, and the exhaust assembly 6 is located inside the riser 2.

[0040] Under the action of external wind, the rainproof hood 3 rotates along the designed rotation direction, driving the rotating shaft assembly 4 to rotate on the supporting assembly 5, and the rotating shaft assembly 4 drives the exhaust assembly 6 to rotate. The rotation of the exhaust assembly 6 generates an upward lift in the riser 2, causing the gas at the lower end of the riser 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 insulating 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 2 extends out of the protective layer 101, and the lower end of the riser 2 extends into the insulating layer 104, thereby discharging the water vapor inside the insulating layer 104 to the outside, ensuring the dryness and air pressure balance inside the roof.

[0042] The vertical pipe 2 is preferably a circular tube made of PVC material, which is corrosion-resistant and weather-resistant. The rainproof hood 3 is a shell-like structure with a hemispherical profile, which blocks the upper end of the vertical pipe 2. The side of the rainproof hood 3 is provided with air holes, which can rotate under the influence of external wind. The designed rotation direction of the rainproof hood 3 is the direction in which the rainproof hood 3 rotates in a specified direction (clockwise or counterclockwise) under the influence of wind. The rotation in the specified direction can be achieved by generating a pressure difference through the pressure difference generated by the several curved blades of the hood itself.

[0043] The rotating shaft assembly 4 includes a rotating shaft 401, an end cap 402, a key segment 403, a rotating ring 404, a keyway 405, and a connecting segment 406. The upper end of the rotating shaft 401 is connected to the rainproof wind cap 3. Specifically, the upper end of the rotating shaft 401 is connected to the rainproof wind cap 3 via the end cap 402. The end cap 402 is welded or clamped to the rainproof wind cap 3. The rotating shaft 401 is welded or clamped to the end cap 402, achieving synchronous rotation of the rainproof wind cap 3 and the rotating shaft 401.

[0044] The middle section of the rotating shaft 401 is a keyed section 403, which engages with a keyway 405 of the rotating ring 404. The keyed section 403 and keyway 405 form a cross-shaped structure that cooperates with each other, enabling the locking transmission of the rotating shaft 401 and the rotating ring 404. The rotating shaft 401 is rotatably mounted on the support assembly 5 via the rotating ring 404. The rotating ring 404 can be a unit that rotatably engages the support assembly 5, or it can be a bearing that enables the rotating motion of the rotating shaft 401 on the support assembly 5.

[0045] The lower end of the rotating shaft 401 is connected to the exhaust component 6. Specifically, the lower section of the rotating shaft 401 is the connecting section 406. The connecting section 406 is connected to the exhaust component 6 by welding or tightening, so that the rotating shaft 401 drives the exhaust component 6 to rotate synchronously.

[0046] The support assembly 5 includes a sleeve 501, an upper support plate 502, a lower support plate 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 mounted on the upper and lower ends of the sleeve 501 to ensure that the rotating shaft 401 can rotate along the axis but cannot move along the axis.

[0047] The sleeve 501 is provided with an upper support plate 502 and a lower support plate 503 that can be moved vertically. The upper support plate 502 and the lower support plate 503 can be adjusted relative to the sleeve 501. After the adjustment is completed, the plates must be fixed. Specifically, the upper outer portion of the sleeve 501 has a positive thread that mates with the inner thread of the upper support plate 502, and the lower outer portion of the sleeve 501 has a reverse thread that mates with the inner thread of the lower support plate 503. When the sleeve 501 rotates in the forward direction, the two support plates move closer to each other, while when the sleeve 501 rotates in the reverse direction, the two support plates move away from each other.

[0048] A plurality of upper support legs 504 and lower support legs 505 are evenly arranged along the circumferential direction between the support upper plate 502 and the support lower plate 503. The support upper plate 502 is hinged to the upper end of the upper support leg 504, and the lower end of the upper support leg 504 is hinged to the upper end of the lower support leg 505 through a pad 506 (the hinged 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 plate 503, and the pad 506 is supported on the inner wall of the riser 2.

[0049] The two support plates move closer together to support the pad outward, forcing pad 506 against the inner wall of riser 2. Friction ensures that support assembly 5 is secured within riser 2 and prevents it from falling. The two support plates move farther apart, retracting the pad inward, loosening pad 506 relative to riser 2, allowing assembly and disassembly of the entire assembly. A spring 507 is installed between the upper support leg 504 and the lower support leg 505. This spring 507 provides preload force to the legs, maintaining pad 506 in an outward-facing position and improving overall stability.

[0050] Due to the adjustable support function of the support plate and the support legs, the support assembly 5 can meet the needs of risers 2 of different forms and specifications, thereby improving the versatility of the device.

[0051] The designed rotation direction of the rainproof hood 3 is the same as the outward support rotation direction of the sleeve 501. The outward support rotation direction of the sleeve 501 is forward rotation, which causes the two support plates to move closer together and support the backing plate outward. When the rainproof hood 3 rotates in the designed rotation direction, the sleeve 501 can also rotate synchronously via the rotating shaft 401. Under the action of the sleeve 501, the backing plate 506 also tends to continuously support outward, thereby ensuring stable support.

[0052] The exhaust assembly 6 includes a central tube 601, exhaust blades 602 and spiral blades 603. The central tube 601 is fixedly connected to the connecting section 406 of the rotating shaft assembly 4. Exhaust blades 602 are provided at the upper and lower ends of the central tube 601, and spiral blades 603 are provided in the middle section of the central tube 601. The exhaust blades 602 and the spiral blades 603 can both generate lift for the gas in the riser 2, thereby achieving the effect of exhaust and moisture-proofing.

[0053] Example 2

[0054] refer to Figures 1 to 7 As shown, a method for installing a roof exhaust device, for the roof exhaust device of Example 1, includes the following steps: First, install the riser 2 on the roof structure 1, the upper end of the riser 2 extends out of the protective layer 101, and the lower end of the riser 2 extends into the insulation layer 104.

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

[0056] The third step is to connect the rotating shaft assembly 4 to the exhaust assembly 6. Insert and fix the connecting section 406 of the rotating shaft 401 into the central tube 601.

[0057] The fourth step is to fix the support assembly 5 in the standpipe 2. The sleeve 501 is rotated to support the backing plate 506, and the backing plate 506 is tightened against the inner wall of the standpipe 2 to fix the device in the standpipe 2.

[0058] The fifth step is to connect the shaft assembly 4 to the rainproof wind cap 3. The upper end of the rotating shaft 401 is fixedly connected to the rainproof wind cap 3 through the end cap 402.
