Anti-overflow transition device for gutters

Abstract

The present invention discloses an anti-overflow transition device for gutters. The device adopts a three-section inner plate. After being installed at the downspout end of the gutter, when the outdoor fluid (rainwater) of the gutter is discharged in bad weather, the device performs physical treatments on the rainwater in sequence, such as turbulent flow deceleration, water flow control energy dissipation, and water flow diffusion, thereby significantly reducing the energy in the rainwater. While reducing the occurrence of overflow and ensuring that the water flows smoothly into the downspout, it can also reduce the occurrence of cavitation, extend the service life of the downspout system materials, and minimize the impact of overflow and cavitation on the rainwater downspout system of the house, thus providing a guarantee for the sound operation of the water supply and drainage equipment of the construction project. The present invention solves the problem that the outdoor water in the existing roof gutter directly flows into the downspout, which easily causes the fixing anchor bolts of the downspout and downpipe to loosen, and the cavitation generated by the outdoor water reduces the service life of the downpipe and downspout.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an anti-overflow transition device for a gutter. Background Art

[0002] Currently, there are almost no protective measures for gutter overflow prevention on the market. The kinetic potential energy of the fluid in the gutter is not converted in advance, resulting in dispersion. This can loosen the anchor bolts securing the downpipes and hoppers, posing a safety hazard. Furthermore, cavitation erosion caused by outdoor water can affect the lifespan of gutters, hoppers, and downpipes to varying degrees.

[0003] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0004] In order to overcome the defects of the existing technology, an anti-overflow transition device for gutters is now provided to solve the problem that the outdoor water in the existing roof gutters directly flows into the downspout, which easily causes the fixing anchor bolts of the downspout and downpipe to loosen, and the cavitation erosion phenomenon generated by the outdoor water reduces the service life of the downpipe and downspout.

[0005] To achieve the above object, an anti-overflow transition device for a gutter is provided, comprising:

[0006] An inner plate is laid at the bottom of the gutter, with opposite sides of the inner plate being turned up to form retaining wall flanges that fit the side walls of the gutter, and a reduced diameter plate formed in the middle sections of the two retaining wall flanges. The reduced diameter plate has opposite ends in the longitudinal direction of the gutter, and the thickness of the reduced diameter plate gradually decreases from the middle of the reduced diameter plate to the opposite ends of the reduced diameter plate;

[0007] Multiple rows of deceleration protrusions are arranged along the length direction of the gutter, each row of deceleration protrusions includes multiple unit blocks formed on the water-facing front section of the inner attached plate, a flow discharge gap is formed between two adjacent unit blocks, and the flow discharge gaps of two adjacent rows of deceleration protrusions are staggered;

[0008] An energy dissipation top sill is formed in the middle section of the inner plate, with both sides of the energy dissipation top sill connected between the middle portions of the two reduced diameter plates, and the thickness of the energy dissipation top sill is greater than the thickness of the unit block;

[0009] Two tooth ridges are arranged at intervals along the length direction of the gutter, and the tooth ridges are formed on the backwater rear section of the inner plate. The height of the tooth ridges is less than or equal to the thickness of the energy dissipation top ridge on the side close to the tooth ridges. The two tooth ridges extend in opposite directions to form a transition portion, and the side of the transition portion away from the tooth ridges forms a slope surface, and the upper end of the slope surface is connected to the top of the tooth ridge.

[0010] Furthermore, the front side of the unit block away from the energy dissipation top sill is arc-shaped.

[0011] Furthermore, the thickness of the unit block gradually decreases from the front side of the unit block to the rear side of the unit block.

[0012] Furthermore, the thickness of the energy dissipation top sill decreases from one end of the energy dissipation top sill close to the deceleration protrusion to the other end of the energy dissipation top sill away from the deceleration protrusion.

[0013] Furthermore, the top surface of the energy dissipation top sill is a curved surface, and the curved surface is S-shaped.

[0014] Furthermore, the thickness of the highest point of the top surface of the energy dissipation sill is 1 / 6 to 1 / 4 of the depth of the gutter.

[0015] Furthermore, the length of the energy dissipation top sill is 2.5 to 10 times the depth of the gutter.

[0016] Furthermore, the end surface of the energy dissipation top sill is arc-shaped.

[0017] The beneficial effect of the present invention is that the anti-overflow transition device for the gutter of the present invention adopts a three-section inner plate. After being installed at the downspout end of the gutter, when the outdoor fluid (rainwater) of the gutter is discharged in bad weather, the rainwater is treated by physical means of turbulence deceleration, water flow control energy dissipation, and water flow diffusion in sequence, thereby greatly reducing the energy in the rainwater. While reducing the occurrence of overflow and ensuring that the water flows smoothly into the downspout, it can also reduce the occurrence of cavitation, extend the service life of the downspout system materials, minimize the impact of overflow and cavitation on the rainwater downspout system of the house, and provide a guarantee for the sound operation of the water supply and drainage equipment of the construction project.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0030] Reference Figures 1 to 7 As shown, the present invention provides an anti-overflow transition device for a gutter, comprising: an inner plate 1, multiple rows of deceleration protrusions 2, an energy dissipation top sill 3, and two tooth sills 4.

[0031] The anti-overflow transition device for the gutter of the present invention is installed at the water collection point of the gutter 5 near the downspout 6. The gutter 5 is installed on the upper part of the structural layer 8. The gutter 5 is connected to the downspout 6. The downspout is connected to the water receiving pipe 7.

[0032] The anti-overflow transition device for a gutter of the present invention is installed in the gutter groove. Specifically, an inner panel 1 is laid on the bottom 51 of the gutter 5. Opposite sides of the inner panel 1 are turned up to form retaining wall flanges 11. These retaining wall flanges 11 adhere to the sidewalls 52 of the gutter 5. The inner panel and retaining wall flanges together form a groove member. The shape and dimensions of the groove member are adapted to the shape and dimensions of the gutter's inner cavity.

[0033] A tapering plate 12 is formed in the middle of the two guardrail flanges 11. The tapering plate 12 has two opposing ends along the length of the gutter 5. The thickness of the tapering plate 12 gradually decreases from the middle portion toward the opposing ends. The tapering plates on the two guardrail flanges reduce the inner diameter of the channel in the middle portion of the groove member.

[0034] The inner plate includes the front section facing the water, the middle section and the front section facing the water. The two ends of the middle section connect the front section facing the water and the front section facing the water. The inner plate is set along the length of the gutter. Figure 5 As shown, the front section facing the water is set towards the direction of the water flow; the rear section facing away from the water is set towards the north direction of the water flow.

[0035] Multiple rows of deceleration protrusions 2 are arranged along the length direction of the gutter 5. Each row of deceleration protrusions 2 includes multiple unit blocks 21. Multiple unit blocks 21 are formed on the upper part of the front section of the inner plate 1 facing the water. Figure 3 A discharge gap 20 is formed between two adjacent unit blocks 21. The discharge gaps 20 of two adjacent rows of deceleration protrusions 2 are staggered.

[0036] For details, see Figures 2 to 4 The front side of the unit block 21 away from the energy dissipation top sill 3 is arc-shaped. The thickness of the unit block 21 gradually decreases from the front side of the unit block 21 to the rear side of the unit block 21.

[0037] In this embodiment, the multiple rows of deceleration protrusions are arranged in a fish scale pattern and are reversely arranged. The reversely arranged fish scale-shaped deceleration protrusions are used to form fluid turbulence in the outdoor water body in the gutter to perform preliminary deceleration of the fluid.

[0038] The energy dissipation top sill 3 is formed at the upper portion of the middle section of the inner attachment plate 1. Both sides of the energy dissipation top sill 3 are connected between the middle portions of the two diameter-reducing plates 12. The thickness of the energy dissipation top sill 3 is greater than the thickness of the unit block 21.

[0039] In the embodiment, in order to be suitable for gutters with short distances and large slopes, the thickness of the energy dissipation top sill 3 decreases from one end of the energy dissipation top sill 3 close to the deceleration protrusion 2 to the other end of the energy dissipation top sill 3 away from the deceleration protrusion 2.

[0040] In this embodiment, the top surface of the energy dissipation top sill 3 is a curved surface, and the curved surface is S-shaped.

[0041] The thickness d at the highest point of the top surface of the energy dissipation sill is 1 / 6 to 1 / 4 of the depth c of the gutter 5 .

[0042] See Figure 1 The top surface of the energy dissipation sill is generally lower on the left and higher on the right, forming a smooth curved surface. Figure 2 The space where the energy dissipation sill is located forms a dumbbell-shaped flow channel (fluid passage) between the reduced diameter plates on the inner side of the retaining wall flange. The smooth curved surface of the sill and the dumbbell-shaped flow channel in the middle section of the inner plate further reduce the fluid velocity.

[0043] The dumbbell-shaped flow channel is designed based on the overflow calculation principle of the WES (Water Experiment Station) standard profile curve and the Kriegel-Offitseroff curve (abbreviated as Kriegel-Offitseroff curve), which can effectively offset the kinetic energy of the fluid.

[0044] In this embodiment, the flow coefficient of the outdoor fluid in the gutter is large, and the required overflow front edge is shorter, which can reduce costs compared with a longer top sill. It is suitable for gutter projects with larger slopes and shorter gutter lengths.

[0045] Behind the energy dissipation top sill, two rows of toothed sills 4 are spaced apart along the length of the gutter 5. Each row of toothed sills extends along the width of the gutter. The toothed sills 4 are formed on the rearward end of the inner plate 1, facing away from the water. The height of the toothed sills 4 is equal to or less than the thickness of the energy dissipation top sill 3 on the side closest to the toothed sill 4. The two toothed sills 4 extend in opposite directions to form a transition portion 41. A sloped surface 410 is formed on the side of the transition portion 41 facing away from the toothed sill 4. The upper end of the sloped surface connects to the top of the toothed sill 4.

[0046] The cross-section of the toothed sill (including the transition section) is an overall right-angled trapezoid. The two spaced toothed sills can reduce the number of air bubbles in the outdoor fluid after the kinetic and potential energy has been dissipated by the energy dissipation sill. This prevents a large number of air bubbles from entering the downspout and downpipe, minimizing cavitation damage to the downspout system (downspout and downpipe), extending the downspout system's service life, and reducing the chance of loosening the anchor bolts securing the downpipe and downspout, thereby improving safety.

[0047] The anti-overflow transition device for the gutter of the present invention adopts a three-section inner attached plate. After being installed at the downspout end of the gutter, when the outdoor fluid (rainwater) of the gutter is discharged in severe weather, the energy in the rainwater is greatly reduced by performing physical means such as turbulence deceleration, water flow control energy dissipation, and water flow diffusion in sequence. While reducing the occurrence of overflow and ensuring that the water flows smoothly into the downspout, it can also reduce the occurrence of cavitation, extend the service life of the downspout system materials, minimize the impact of overflow and cavitation on the rainwater downspout system of the house, and provide a guarantee for the sound operation of the water supply and drainage equipment of the construction project. Example

[0048] Reference Figure 8 and Figure 9 As shown, the present invention provides an anti-overflow transition device for a gutter, comprising: an inner plate 1, multiple rows of deceleration protrusions 2, an energy dissipation top sill 3, and two tooth sills 4.

[0049] The difference between the anti-overflow transition device for the gutter in this embodiment and the anti-overflow transition device for the gutter in the first embodiment is the structure of the energy dissipation top sill.

[0050] Specifically, the energy dissipation top sill in the first embodiment is shorter and has a non-uniform thickness. In this embodiment, the energy dissipation top sill is longer and has a uniform thickness.

[0051] The anti-overflow transition device for the gutter in this embodiment is mostly used in gutter projects with small flow or small slope and long gutter length. The length e of the energy dissipation top sill 3 is 2.5 to 10 times the depth c of the gutter 5.

[0052] Specifically, the energy dissipation top sill has a water-facing end facing the water flow direction and a water-receiving end facing away from the water flow direction. The end face of the energy dissipation top sill 3 is arc-shaped to avoid the generation of turbulence and the introduction of cavitation.

[0053] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
