Description

Technical Field

[0001] The utility model relates to the technical field of eaves gutters, in particular to a filtering type eaves gutter. Background Art

[0002] The gutter is a water collection ditch on the side of the eaves. When it rains, the rainwater on the eaves flows into the gutter and then is led to the ground through the riser. In general, in order to prevent leaves or other debris from entering the riser and causing the riser to be blocked, a leaf screen is usually set at the rainwater inlet of the gutter to prevent leaves or other debris from entering the riser. However, when it rains, leaves or other debris that fall into the gutter will accumulate on the leaf screen under the dual effects of gravity and water flow. If they are not cleaned up in time, they will block the leaf screen and affect the normal discharge of rainwater in the gutter. Especially during heavy rain, when the leaf screen is blocked, the rainwater in the gutter cannot be discharged in time, and the gutter is in a full flow state for a long time. After full flow, the excess rainwater in the gutter will overflow through the top of the gutter, causing erosion to the wall of the building adjacent to the gutter.

[0003] Traditional plastic gutters have the advantages of being lightweight, easy to install and low in cost. They are often used to collect and discharge rainwater from roofs in buildings. However, as buildings using gutters are generally not very tall, leaves, branches and other foreign objects often fall from roofs and balconies. These foreign objects will flow into the gutters with rainwater. Over time, these foreign objects will accumulate in the gutters, hindering drainage. In addition, because the gutters are installed under the eaves at a relatively high height, daily cleaning and maintenance are inconvenient, and even worse, professional cleaning is required. Utility Model Content

[0004] The utility model provides a filtering type eaves ditch which has a simple structure and is convenient for cleaning foreign objects dropped on the eaves ditch.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A filter type eaves gutter, comprising an eaves gutter body and a filter assembly co-extruded with the eaves gutter body, wherein the cross section of the eaves gutter body is a semicircular structure with a hollow interior;

[0007] The two ends of the gutter body along the semicircular arc surface are respectively provided with a first extension portion and a second extension portion, and the length of the second extension portion is greater than that of the first extension portion;

[0008] The ends of the first extension part and the second extension part away from the gutter body are both provided with parallel grooves with a certain slope, and the filter components are embedded in the grooves.

[0009] As a preferred technical solution of the utility model, the lengths of both ends of the filter assembly are adapted to the length of the gutter body extending along the gutter direction.

[0010] As a preferred technical solution of the present utility model, the first elongated portion, the second elongated portion and the gutter body are integrally formed.

[0011] As a preferred technical solution of the present utility model, the filter component is a leaf barrier net.

[0012] As a preferred technical solution of the present utility model, the leaf separator net is a flat plate.

[0013] As a preferred technical solution of the utility model, the thickness of the barrier leaf net is 0.3-1 mm.

[0014] As a preferred technical solution of the utility model, a plurality of laterally arranged filter mesh holes are provided in the middle of the leaf barrier net.

[0015] As a preferred technical solution of the present invention, a plurality of parallel through holes are provided on both sides of the filter assembly.

[0016] As a preferred technical solution of the utility model, the gutter body is made of polyvinyl chloride material or rigid polyvinyl chloride material.

[0017] As a preferred technical solution of the present utility model, the filter assembly is made of metal.

[0018] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0019] 1. Low cost, simpler construction and installation. Although the existing gutter can be equipped with a filter assembly, the added filter assembly needs to be fixed with screws, and drilling holes is required to damage the surface of the gutter. The gutter is prone to breakage during drilling, which is a test of the construction personnel's skills. In addition, the installation generates additional labor costs, which is costly. The gutter of the utility model embeds the filter assembly inside the gutter through an integrated co-extrusion molding method, without the need for additional fixed installation, thereby simplifying the construction process and saving construction costs.

[0020] 2. The structure is simple, which is convenient for cleaning foreign objects falling on the gutter. The gutter body is provided with a first extension part and a second extension part at both ends along the semicircular arc surface, and the length of the second extension part is greater than that of the first extension part; so that the filter assembly after the filter-type gutter is installed is inclined, and foreign objects are not easily accumulated on the filter assembly.

[0030] Example 1

[0031] For easier understanding, see Figure 1 The utility model provides an embodiment of a filter-type eaves gutter, comprising an eaves gutter body 1, and a filter assembly 2 co-extruded with the eaves gutter body 1, wherein the cross section of the eaves gutter body 1 is a semicircular structure with a hollow interior;

[0032] The gutter body 1 is provided with a first extension portion 11 and a second extension portion 12 at both ends along the semicircular arc surface, and the length of the second extension portion 12 is greater than that of the first extension portion 11;

[0033] The ends of the first extension portion 11 and the second extension portion 12 away from the gutter body 1 are both provided with parallel grooves 13 with a certain slope, and the filter assembly 2 is embedded in the grooves 13 .

[0034] The displacement of the filter assembly 2 is limited, and the filter assembly 2 with an inclination is arranged obliquely, so that foreign matter can be more easily removed from the top of the gutter. After the filter assembly 2 is co-extruded on the gutter body 1, the gutter body 1 is installed forwardly, and the filter assembly 2 is inclined.

[0035] The bottom of the gutter has a semicircular cross-section. Compared with the traditional rectangular structure, the semicircular cross-section helps to have a higher water level under the same rainwater flow, avoiding the phenomenon that foreign objects entering the gutter are stranded at the bottom of the gutter and cannot be discharged.

[0036] The use of the eaves gutter of the utility model is similar to that of the eaves gutter on the market. The eaves gutter is fixed under the eaves of the building through the eaves gutter bracket. After fixing, the filter assembly will be tilted at a certain angle. The product structure is simple, the process is mature, and the feasibility is high. Compared with the mainstream metal and plastic eaves gutters on the market, the utility model has a higher cost performance.

[0037] Example 2

[0038] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0039] like Figures 1 to 3As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the lengths of both ends of the filter assembly 2 are adapted to the length of the gutter body 1 extending along the gutter direction, so that the overall structure is beautiful.

[0040] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above method, further, the first extension portion 11, the second extension portion 12 and the gutter body 1 are integrally formed.

[0041] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the filter component 2 is a leaf barrier net.

[0042] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the leaf barrier net is a flat plate, which is easy to be made into a roll, thereby facilitating the co-extrusion molding of the gutter body 1 and the filter assembly 2.

[0043] like Figures 1 to 3 As shown, as a preferred implementation, based on the above-mentioned method, further, the thickness of the barrier leaf net is 0.3 to 1 mm, and the moderate thickness can save materials.

[0044] Furthermore, the groove 13 can be set as an arc-shaped groove, and the edge of the leaf separator net can be set as an arc-shaped convexity, and the width of the arc-shaped groove is greater than the thickness of the arc-shaped convexity, so that the arc-shaped groove can slide on the arc-shaped convexity.

[0045] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above-mentioned embodiment, further, a plurality of laterally arranged filter mesh holes 22 are provided in the middle of the leaf screen.

[0046] Preferably, the length of the filter assembly 2 is preferably in the range of 7 cm to 30 mm. The filter mesh holes 22 can be long strip holes, the length direction of which is the vertical direction, the hole spacing between two adjacent filter mesh holes 22 is t1, and the value range of t1 is preferably 3 mm to 10 mm.

[0047] Alternatively, in each group of filter mesh holes 22, the arrangement of the filter mesh holes 22 may also be in the shape of other regular polygons, and the center of the regular polygon is also arranged with a filter mesh hole 22.

[0048] like Figures 1 to 3As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a plurality of parallel through holes 21 are provided on both sides of the filter component 2, and the gutter body 1 and the filter component 2 are manufactured by co-extrusion molding. When the gutter is co-extruded, molten glue is set at the groove 13 of the gutter body 1, and the molten glue passes through the through holes 21 of the filter component 2, and is embedded in the through holes 21 of the filter component 2 through the gutter body 1. When the gutter body 1 is cooled and formed, the filter component 2 is compounded with the gutter body 1.

[0049] It should be noted that the molten glue on the outside of the groove 13 of the gutter body 1 is squeezed by the filter assembly 2, so that the gutter body 1 and the filter assembly 2 achieve a sealing effect, and there is no need to install other auxiliary parts to squeeze the molten glue, and the installation is simple and reliable.

[0050] Preferably, the through hole 21 is a circular hole, and the diameter is preferably in the range of 1 mm to 3 mm. On the same side of the filter assembly 2, the spacing between two adjacent groups of through holes 21 is t2, and the value range of t2 is preferably 2 mm to 6 mm. Alternatively, the through hole 21 can also be a hexagonal hole with a side length of 1.5 mm to 3 mm, or a rectangular hole with a size of 1.5 mm to 3 mm*1.5 mm to 3 mm.

[0051] like Figures 1 to 3 As shown, as a preferred embodiment, based on the above method, the filter assembly 2 further includes a multi-layer leaf mesh, and the multi-layer leaf mesh is stacked along the thickness direction of the leaf mesh. In this way, the multi-layer leaf mesh of the filter assembly 2 can achieve multiple coarse filtration of foreign matter entering the gutter body 1, thereby better intercepting and improving the filtering effect of the filter assembly 2.

[0052] Specifically, the filter assembly 2 can be formed by stacking multiple layers of leaf mesh. The leaf mesh can be made of reusable materials. For example, the filter assembly 2 can be composed of multiple layers of stainless steel wire mesh, the apertures of the multiple layers of stainless steel wire mesh can be different, and the multiple layers of stainless steel wire mesh can be reused after being rinsed with water.

[0053] When in use: When the device is needed, the eaves gutter can be fixed on the roof by manpower. The cross section of the prior art eaves gutter is semi-open, and the cross section is not closed, which makes the strength and rigidity of the eaves gutter relatively weak. It is easily deformed, aged, and even cracked due to the long-term influence of rain erosion and temperature changes. The eaves gutter of the utility model adopts a steel-plastic composite method, and by taking advantage of the strength and high rigidity of metal materials, the strength and rigidity of the eaves gutter cross section are guaranteed to the greatest extent.

[0054] Example 3

[0055] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0056] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the gutter body 1 is made of polyvinyl chloride material or rigid polyvinyl chloride material.

[0057] Polyvinyl chloride has the advantages of strong plasticity, high safety, good flexibility and low price. The eaves gutter disclosed in the embodiment of the utility model is safe and reliable, avoiding the problem of rainwater flowing into the room, and the source of the manufacturing material is wide, and the manufacturing technology is feasible.

[0058] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the filter assembly 2 is made of metal material, that is, stainless steel, aluminum alloy, galvanized sheet, copper or other metal materials, which can be set according to the actual connection requirements. Since stainless steel, galvanized sheet and copper are relatively hard, the stability of the use of the filter assembly 2 can be improved. The density of aluminum material is lower than that of copper material, and the cost of aluminum material is lower than that of copper material. Therefore, when the filter assembly 2 made of aluminum material is used as the partition net material of the gutter body 1, the weight can be reduced and the cost can be reduced.

[0059] In the prior art, since the cross section of the eaves gutter is semi-open and the cross section is not closed, the strength and rigidity of the eaves gutter are relatively weak. It is easily deformed, aged, and even cracked due to the long-term influence of rainwater erosion and temperature changes. The utility model is an integrated co-extruded steel-plastic composite filter eaves gutter, which effectively increases the structural strength and rigidity by combining steel and plastic and closing the cross section. In addition, by adding a filter structure on the surface of the eaves gutter, it can effectively intercept leaves, branches and other debris to prevent them from entering the eaves gutter and causing blockage, which helps to keep the eaves gutter unobstructed, ensure that rainwater can be discharged smoothly, and reduce maintenance costs and workload.

[0060] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
