Description

Technical Field

[0001] This utility model relates to the field of roof drainage technology, specifically a siphon device for roof drainage. Background Technology

[0002] Commercial and industrial buildings are typically constructed with flat or nearly flat roofs. Flat roofs require drainage systems to prevent excessive accumulation of water from rain and snowmelt, thus avoiding structural loads that could cause the roof to collapse. Building standards generally require flat roofs to include roof drains positioned to facilitate the drainage of most water through the plumbing system. The openings of the roof drains are typically covered by some form of grille or filter to prevent large objects from being sucked into the plumbing system. In a typical roof drain construction, the filter or grille takes the form of a hemispherical filter to prevent or minimize clogging of the roof drains caused by the accumulation of leaves and other debris that may accumulate on the roof.

[0003] Existing roof drainage systems often suffer from water accumulation in pipes that can easily mix with air, leading to poor drainage and reduced efficiency. Therefore, this system does not meet current requirements. To address this issue, we propose a siphon device for roof drainage. Utility Model Content

[0004] The purpose of this utility model is to provide a siphon device for roof drainage, so as to solve the problem mentioned in the background art that when existing roof drainage is carried out, air can easily mix into the water in the pipe, which can easily cause the water to be discharged poorly and affect the drainage effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a siphon device for roof drainage, comprising a drainage siphon mechanism, wherein the drainage siphon mechanism includes a guide sleeve, an installation ring is installed at the upper end of the guide sleeve, a retaining ring is installed above the installation ring, a plurality of first partition plates and second partition plates are installed between the installation ring and the retaining ring, a central sealing plate is installed on the inner side of the plurality of first partition plates and second partition plates, and a drainage gap is provided between the installation ring and the retaining ring and the central sealing plate.

[0006] Preferably, a drainage riser is installed below the flow guide sleeve, and an adaptive full-flow mechanism is installed between the flow guide sleeve and the drainage riser. The adaptive full-flow mechanism includes a connecting pipe, a second limiting ring is installed on the inner side of the connecting pipe, a support spring is provided on the upper end face of the second limiting ring, a conical flow divider is installed on the upper end of the support spring, an elastic plate is installed between the conical flow divider and the support spring, a plurality of swirling fins are fixedly provided on the surface of the conical flow divider, a first limiting ring is installed in the middle of the upper end face of the conical flow divider, a central connecting rod is installed on the inner side of the first limiting ring, and a double-cone flow guide seat is installed above the conical flow divider.

[0007] Preferably, the upper end of the guide sleeve is fixedly connected to the mounting ring, and the mounting ring, retaining ring and central sealing plate are fixedly connected by a plurality of first partition pieces and second partition pieces, which are arranged in an alternating circular pattern relative to the center of the central sealing plate.

[0008] Preferably, the bottom end of the central connecting rod passes through the central sealing plate, the first limiting ring, the conical diverter seat, the elastic plate and the support spring in sequence, and is connected to the second limiting ring by a thread. The upper end of the central connecting rod is connected to the central sealing plate by a thread.

[0009] Preferably, the elastic plate is connected to the second limiting ring by a support spring, the first limiting ring is connected to the central connecting rod by a thread, the elastic plate is fixedly connected to the conical diverter seat, the first limiting ring is in close contact with the upper end face of the conical diverter seat, the conical diverter seat and multiple swirl fins are integrally die-cast, and the multiple swirl fins are arranged circumferentially relative to the axis of the central connecting rod.

[0010] Preferably, the double-cone flow guide seat is fixedly connected to the flow guide sleeve, the flow guide sleeve is fixedly connected to the drainage riser through a connecting pipe, and the mounting ring, the double-cone flow guide seat and the conical flow divider are coaxial.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses multiple first dividing plates arranged in a circle to initially divide the accumulated water and guide it through the drainage gap between the retaining ring and the central sealing plate. At the same time, multiple second dividing plates arranged in a circle further divide the accumulated water and guide it to the inner side of the guide sleeve through the drainage gap between the mounting ring and the central sealing plate. The drainage gap can reduce the drainage depth, and the space inside the guide sleeve is larger than the drainage gap, so that the accumulated water can generate a siphon effect when passing through the drainage gap and the guide sleeve in sequence, thereby improving the drainage efficiency of the accumulated water.

[0013] 2. This utility model uses a double-cone guide seat to change the diameter of the inner side of the bottom end of the guide sleeve and generates swirling flow through the guiding effect of multiple swirling fins. At the same time, the conical diverter seat can adjust its height according to different flow rates of water under the elastic support of the support spring via an elastic plate. When the flow rate inside the guide sleeve increases, the conical diverter seat is impacted by the water and the elastic plate drives the support spring to elastically contract, thereby increasing the distance between the conical diverter seat and the double-cone guide seat. This satisfies the discharge of water at different flow rates and keeps the water in a full flow state when passing between the conical diverter seat and the double-cone guide seat, further improving the siphon effect of the drainage siphon mechanism. The first limiting ring facilitates the limiting of the conical diverter seat, maintaining the minimum distance between the conical diverter seat and the double-cone guide seat and avoiding blockage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1 and Figure 2This utility model provides an embodiment of a roof drainage siphon device, including a drainage siphon mechanism 1. The drainage siphon mechanism 1 includes a guide sleeve 106, an installation ring 101 installed at the upper end of the guide sleeve 106, and the upper end of the guide sleeve 106 is fixedly connected to the installation ring 101. A retaining ring 102 is installed above the installation ring 101. A plurality of first partition plates 103 and second partition plates 104 are installed between the installation ring 101 and the retaining ring 102. A central sealing plate 105 is installed on the inner side of the plurality of first partition plates 103 and second partition plates 104. The separator 103 and the second separator 104 are arranged alternately in a circle relative to the center of the central sealing plate 105. The mounting ring 101, the retaining ring 102 and the central sealing plate 105 are fixedly connected by multiple first separators 103 and second separators 104. Drainage gaps are provided between the mounting ring 101 and the retaining ring 102 and the central sealing plate 105. The drainage depth can be reduced through the drainage gaps, and the space inside the guide sleeve 106 is larger than the drainage gaps, so that when the accumulated water passes through the drainage gaps and the guide sleeve 106 in sequence, a siphon effect can be generated, thereby improving the drainage efficiency of the accumulated water.

[0020] Please see Figure 2 and Figure 3 A drainage riser 3 is installed below the flow guide sleeve 106. An adaptive full-flow mechanism 2 is installed between the flow guide sleeve 106 and the drainage riser 3. The adaptive full-flow mechanism 2 includes a connecting pipe 208. The flow guide sleeve 106 and the drainage riser 3 are fixedly connected through the connecting pipe 208. A second limiting ring 207 is installed on the inner side of the connecting pipe 208. A support spring 206 is provided on the upper end face of the second limiting ring 207. A conical flow divider 203 is installed on the upper end of the support spring 206. A double-cone flow guide 20 is installed above the conical flow divider 203. 2. The mounting ring 101, the double-cone guide seat 202, and the conical diverter seat 203 are coaxial. The double-cone guide seat 202 is fixedly connected to the guide sleeve 106. An elastic plate 204 is installed between the conical diverter seat 203 and the support spring 206. The elastic plate 204 is fixedly connected to the conical diverter seat 203. The elastic plate 204 is connected to the second limiting ring 207 through the support spring 206. The conical diverter seat 203 can adjust its height according to the different flow rates of water under the elastic support of the support spring 206 through the elastic plate 204.

[0021] Multiple swirl fins 209 are fixedly provided on the surface of the conical flow divider 203. The conical flow divider 203 and the multiple swirl fins 209 are integrally die-cast. The multiple swirl fins 209 are arranged circumferentially relative to the axis of the central connecting rod 201. A first limiting ring 205 is installed in the middle of the upper end face of the conical flow divider 203. The first limiting ring 205 is in close contact with the upper end face of the conical flow divider 203. The first limiting ring 205 is threadedly connected to the central connecting rod 201. The inner surface of the first limiting ring 205... A central connecting rod 201 is installed on the side. The upper end of the central connecting rod 201 is threadedly connected to the central sealing plate 105. The bottom end of the central connecting rod 201 passes through the central sealing plate 105, the first limiting ring 205, the conical diverter seat 203, the elastic plate 204 and the support spring 206 in sequence, and is threadedly connected to the second limiting ring 207. This can keep the water in a full flow state when passing between the conical diverter seat 203 and the double conical guide seat 202, and further improve the siphon effect of the drainage siphon mechanism 1.

[0022] When in use, during roof drainage operations, the guide sleeve 106 is inserted into the inner side of the roof drain and fixedly installed on the roof. At this time, the lower end face of the mounting ring 101 is in close contact with the roof. The bottom end of the guide sleeve 106 is connected to the plastic drainage riser 3 through the connecting pipe 208. When there is water accumulation on the roof, there are drainage gaps between the mounting ring 101 and the retaining ring 102 and the central sealing plate 105, so that the multiple first partition plates 103 arranged in a circle can initially divide the water accumulation and guide it through the drainage gap between the retaining ring 102 and the central sealing plate 105.

[0023] Meanwhile, the accumulated water is further divided by multiple second dividing plates 104 arranged in a circle and guided to the inside of the guide sleeve 106 through the drainage gap between the mounting ring 101 and the central sealing plate 105. The drainage gap can reduce the drainage depth, and the space inside the guide sleeve 106 is larger than the drainage gap, so that the accumulated water can generate a siphon effect when passing through the drainage gap and the guide sleeve 106 in sequence, thereby improving the drainage efficiency of the accumulated water.

[0024] A retaining ring 102 is fixedly installed on the inner side of the flow guide sleeve 106, and multiple swirl fins 209 are provided between the conical flow divider 203 and the double conical flow guide 202, so that the inner side of the bottom end of the flow guide sleeve 106 can be changed through the double conical flow guide 202 and swirl can be generated through the guiding effect of multiple swirl fins 209. At the same time, the conical flow divider 203 can be height adjusted according to the different flow rates of water accumulation through the elastic plate 204 under the elastic support of the support spring 206.

[0025] Specifically, when the flow rate inside the guide sleeve 106 increases, the conical diverter seat 203 is impacted by the accumulated water. Through the elastic plate 204, the support spring 206 is elastically contracted, thereby increasing the distance between the conical diverter seat 203 and the double-conical guide seat 202. This satisfies the discharge of accumulated water at different flow rates and keeps the accumulated water in a full flow state when passing between the conical diverter seat 203 and the double-conical guide seat 202, further improving the siphon effect of the drainage siphon mechanism 1. The first limiting ring 205 facilitates the limiting of the conical diverter seat 203, maintaining the minimum distance between the conical diverter seat 203 and the double-conical guide seat 202, and avoiding blockage.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
