Abstract
Description
Technical Field
[0001] The invention relates to a roof gutter, which can filter debris such as leaves on the basis of solving the problem of rainwater overflow to prevent the drainage pipeline of the roof gutter from being blocked; and can realize self-cleaning of debris such as leaves, so as to effectively maintain good drainage performance for a long time. Background Art
[0002] The top of traditional roof gutters is mostly designed to be open. In the process of draining rainwater, leaves and other garbage often fall into the gutter. Long-term accumulation can easily lead to blockage of the drainage pipe of the roof gutter, thus affecting the normal use of the roof gutter. Therefore, the opening of the existing roof gutter is generally provided with a corresponding filter mesh to filter the leaves and other garbage. However, the setting of the filter mesh also has an obvious defect: when the amount of rainwater is large, some rainwater often does not have time to pass through the holes of the filter mesh to enter the gutter and overflows along the edge of the filter mesh, thereby causing the wall of the building to be wet.
[0003] To solve this problem, some current methods are to lower the installation height of the filter mesh so that rainwater that cannot pass through the filter mesh in time can gather on the upper part of the filter mesh. However, the amount of rainwater collected on the upper part of the filter mesh is still greater than its filtering flow rate, so the problem of rainwater overflow will eventually occur, at least the time of rainwater overflow is delayed. In addition, this will also cause leaves and other garbage that enter the roof gutter to gather on the upper part of the filter mesh, eventually blocking the holes of the filter mesh in a large area, which is very troublesome.
[0004] Therefore, the purpose of the present invention is to design a roof gutter that can effectively filter out debris such as leaves on the basis of solving the problem of rainwater overflow to prevent the drainage pipes of the roof gutter from being blocked; and can achieve self-cleaning of debris such as leaves, thereby effectively maintaining good drainage performance for a long time. Summary of the invention
[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a roof gutter which can effectively solve the problems existing in the above-mentioned prior art.
[0006] The technical solution of the present invention is:
[0007] A roof gutter, comprising
[0008] The gutter body comprises a drainage groove and a filter cover plate fixed on the top of the drainage groove, wherein a plurality of corresponding first filter holes are evenly distributed on the filter cover plate, a corresponding drainage pipe is downwardly connected to the bottom of one side of the drainage groove, and a sewage discharge notch is arranged on the filter cover plate on one side close to the drainage pipe;
[0009] The movable cover plate has a gap with the sewage discharge notch of the filter cover plate, the movable cover plate can be opened and closed at the sewage discharge notch of the filter cover plate, and a plurality of corresponding second filter holes are evenly distributed on the movable cover plate;
[0010] The cover driving device comprises a water baffle, wherein the end of the water baffle away from the drain pipe is tilted downward, and the end of the water baffle away from the drain pipe is spaced apart from the bottom surface of the drain ditch, the movable cover is fixedly connected to the water baffle by corresponding connecting rods, and at least one corresponding elastic member is fixed between the bottom of the water baffle and the bottom surface of the drain ditch.
[0011] The end of the water baffle away from the drain pipe is tilted downward by at least 30 degrees. The elastic member is a coil spring, and the number of the elastic member is one. The elastic member is arranged on the side of the water baffle close to the drain pipe, and the elastic member is vertically arranged between the water baffle.
[0012] When the water level flowing through the drainage ditch continuously exceeds the height of the end of the water baffle away from the drain pipe, the end of the water baffle away from the drain pipe swings downward under the water flow pressure, the elastic member is compressed, and the water baffle is driven by the water flow pressure until the end of the water baffle away from the drain pipe abuts against the bottom surface of the drainage ditch.
[0013] A corresponding drainage filtering device is arranged at the connection point between the drainage pipe and the drainage groove.
[0014] The drainage filter device includes a hemispherical filter cover, on which a plurality of corresponding filter holes are arranged at intervals, and the widths of the filter holes are arranged in increasing order from top to bottom; a plurality of limiting rods distributed in a ring shape are vertically arranged downward from the bottom of the hemispherical filter cover, and the spacing between two adjacent limiting rods is greater than the maximum width of the filter holes; the lower side of the drain pipe is downwardly connected to a limiting mounting tube through an annular connecting plate, and a fixing device at the connection between the hemispherical filter cover and the limiting rod is provided with an annular float, the bottom of the annular float abuts against the annular connecting plate, and the limiting rods are respectively inserted into the limiting mounting tube.
[0015] A gap is provided between the outer end of the limiting rod and the inner side wall of the limiting mounting tube.
[0016] The hemispherical filter cover comprises an annular metal rod, a corresponding metal sheet is arranged on the upper side of the center of the annular metal rod, and a plurality of arc-shaped metal rods are fixedly welded in an annular array between the annular metal rod and the metal sheet.
[0017] The top ends of the limiting rods are respectively fixedly welded to the bottom sides of the annular metal rods.
[0018] The cross sections of the filter cover plate and the movable cover plate are both V-shaped and concave.
[0019] The bottom ends of the filter cover plate and the movable cover plate are both arranged in an arc shape, and the first filter hole and the second filter hole are not arranged at the bottom ends of the filter cover plate and the movable cover plate respectively.
[0020] Advantages of the present invention:
[0021] 1) During use, the present invention is installed on the roof of a corresponding building, and the corresponding drainage pipeline is connected to the drainage pipe of the present invention to drain the water in the drainage ditch in time.
[0022] On sunny days, the filter cover and the movable cover can effectively filter out debris such as leaves to prevent them from directly entering the drainage ditch, thereby effectively preventing the drainage pipe from being directly blocked;
[0023] When it rains lightly, rainwater can directly enter the drainage ditch through the filter cover plate and the first and second filter holes of the movable cover plate. At this time, the water level flowing through the drainage ditch does not exceed the height of the end of the water retaining plate away from the drainage pipe. The rainwater flows between the water retaining plate and the bottom of the drainage ditch and is then discharged along the drainage pipe. At this time, leaves and other debris cannot enter the drainage ditch, so as to ensure that leaves and other debris will not enter the drainage pipe with a smaller rainwater flow, thereby preventing leaves and other debris from gathering at the bends of the drainage pipe, so as to prevent leaves and other debris from accumulating and clogging in the drainage pipe connected to the drainage pipe while the rainwater is discharged smoothly.
[0024] When it rains heavily, a large amount of rainwater flows into the drainage groove along the filter cover plate and the first and second filter holes of the movable cover plate, so that the water level flowing through the drainage groove exceeds the height of the end of the water retaining plate away from the drainage pipe. At this time, the water flow can form pressure on the end of the water retaining plate away from the drainage pipe, and the end of the water retaining plate away from the drainage pipe is forced to swing downward, and the elastic member is compressed until the water retaining plate is pushed as a whole to the end of the water retaining plate away from the drainage pipe to abut against the bottom surface of the drainage groove; the rainwater flows on the upper side of the water retaining plate, so that under the action of the water flow pressure The installation height of the water retaining plate is effectively lowered, and then the installation height of the movable cover plate is lowered as the water retaining plate goes down, so that the movable cover plate and the filter cover plate are arranged in a spaced state; in this way, part of the rainwater can enter the drainage ditch through the first filter hole of the filter cover plate, and the rainwater that does not have time to enter the drainage ditch through the first filter hole can be directly discharged into the drainage ditch along the connection gap between the filter cover plate and the movable cover plate, thereby effectively solving the overflow problem caused by the rainwater not having time to enter the drainage ditch through the filter cover plate in heavy rain weather.
[0025] 2) Due to the design of the movable cover plate and the cover plate driving device of the present invention, the movable cover plate and the filter cover plate can be arranged in a spaced state during heavy rain weather. This can not only greatly improve the drainage effect to solve the overflow problem caused by the rainwater not having enough time to enter the drainage ditch through the filter cover plate during heavy rain weather; but also can flush the leaves and other debris originally filtered on the filter cover plate and the movable cover plate into the drainage ditch, and then under the flushing of large flow of rainwater (large water flow pressure), the leaves and other debris are directly flushed out of the drainage pipeline, thereby realizing the self-cleaning of leaves and other debris, so as to effectively maintain the good drainage performance of the present invention for a long time.
[0026] 3) Although the filter cover or movable cover can filter leaves and other debris on sunny days or light rainy days, as the service life increases, the first filter hole and the second filter hole on the filter cover or movable cover will inevitably have a small area of damage, or due to other reasons, a small amount of leaves and other debris will enter the drainage groove, resulting in the drainage pipeline connected to the drainage pipe being blocked. For this reason, the present invention further provides a corresponding drainage filter device at the junction of the drainage pipe and the drainage groove, and the drainage filter device includes a hemispherical filter cover, and a plurality of limit rods distributed in an annular shape are vertically arranged downward at the bottom of the hemispherical filter cover, and the spacing between two adjacent limit rods is greater than the maximum width of the filter hole.
[0027] When the water level flowing through the drainage ditch is relatively low, the buoyancy height of the annular float is relatively low. At this time, the rainwater flowing through the drainage pipe and the limit installation pipe is mainly filtered through the hemispherical filter cover. At this time, even if a small amount of debris such as leaves enters the drainage ditch with the rainwater, it will be isolated outside the drainage pipe by the hemispherical filter cover, thereby further preventing debris such as leaves from entering the drainage ditch from accumulating at the bends of the drainage pipe and eventually causing blockage points.
[0028] When the water level flowing through the drainage ditch is relatively high, that is, in heavy rain, under the action of the annular float, the drainage filter device of the present invention floats as a whole. At this time, the rainwater filtering surface is replaced by the original hemispherical filter cover with a ring-shaped distributed limiting rod, so that the water flow entering the drainage pipe can be quickly increased to adapt to the discharge of large-flow rainwater, and the filtering interval can be effectively increased, so that debris such as leaves can enter the drainage pipe and the limiting installation pipe through between two adjacent limiting rods. Since the water flow / water flow pressure is large at this time, debris such as leaves can be effectively flushed out of the drainage pipe, so as to further realize the self-cleaning of debris such as leaves and prevent the drainage pipe from being blocked.
[0029] 4) The lower side of the drainage pipe of the present invention is downwardly connected to the limiting installation pipe through an annular connecting plate. During use, the drainage pipeline can be effectively connected through the limiting installation pipe, and the limiting rod can be installed through the limiting installation pipe. The annular connecting plate can be used to abut and fix the annular float of the drainage filter device, so as to ensure that the drainage filter device of the present invention can be limited and movable between the drainage pipe and the drainage ditch, thereby ensuring the practical effect of the present invention.
[0030] 5) The cross-sections of the filter cover and the movable cover of the present invention are both V-shaped and concave, and the bottom ends of the filter cover and the movable cover are both curved. The most important thing is that the bottom ends of the filter cover and the movable cover are not provided with the first filter hole and the second filter hole. When the rainfall is small, part of the rainwater enters the drainage ditch through the first filter hole and the second filter hole, while part of the rainwater flows along the bottom ends of the filter cover and the movable cover, and is discharged into the gutter body along the gap between the filter cover and the movable cover; when the rainfall is heavy, the rainwater that does not have time to enter the drainage ditch through the first filter hole of the filter cover and the gap between the filter cover and the movable cover will flow into the movable cover after the position is lowered along the position where the first filter hole is not provided on the filter cover. Firstly, it can effectively increase the downward pressure on the movable cover to ensure that a more stable spacing can be formed between the movable cover and the filter cover; secondly, it can effectively form a water flow to flush leaves and other debris attached to the filter cover to the gap between the filter cover and the movable cover, thereby flushing leaves and other debris into the drainage ditch, to further ensure the self-cleaning of leaves and other debris under a large flow of rainwater.

[0040] When the water level flowing through the drainage ditch 101 continuously exceeds the height of the end of the water baffle 401 away from the drain pipe 2, the end of the water baffle 401 away from the drain pipe 2 swings downward under the water flow pressure, the elastic member 403 is compressed, and the water baffle 401 is driven by the water flow pressure until the end thereof away from the drain pipe 2 abuts against the bottom surface of the drainage ditch 101.
[0041] A corresponding drainage filter device 5 is provided at the connection point between the drainage pipe 2 and the drainage groove 101 .
[0042] The drainage filter device 5 includes a hemispherical filter cover 501, on which a plurality of corresponding filter holes 8 are arranged at intervals, and the width of the filter holes 8 is arranged in an increasing manner from top to bottom; a plurality of limiting rods 502 distributed in a ring shape are vertically arranged downward from the bottom of the hemispherical filter cover 501, and the spacing between two adjacent limiting rods 502 is greater than the maximum width of the filter holes 8; the lower side of the drain pipe 2 is downwardly connected to the limiting mounting tube 7 through the annular connecting plate 6, and the connection fixing device between the hemispherical filter cover 501 and the limiting rod 502 has an annular float 503, the bottom of the annular float 503 abuts against the annular connecting plate 6, and the limiting rods 502 are respectively inserted into the limiting mounting tube 7.
[0043] There is a gap between the outer end of the limiting rod 502 and the inner side wall of the limiting mounting tube 7 .
[0044] The hemispherical filter cover 501 comprises an annular metal rod 5011 , a corresponding metal sheet 5012 is arranged on the upper side of the center of the annular metal rod 5011 , and a plurality of arc-shaped metal rods 5013 are fixedly welded in an annular array between the annular metal rod 5011 and the metal sheet 5012 .
[0045] The top end of the limiting rod 502 is fixedly welded to the bottom side of the annular metal rod 5011 .
[0046] The annular float 503 in this embodiment is made of a hollow annular plastic part, but is not limited to a hollow annular plastic part. The annular float 503 can also be made of a foam part with obvious buoyancy, etc. The annular float 503 is fixed to the connection between the hemispherical filter cover 501 and the limiting rod 502 by tightening with wire.
[0047] The cross sections of the filter cover plate 102 and the movable cover plate 3 are both V-shaped and concave. The bottom ends of the filter cover plate 102 and the movable cover plate 3 are both curved, and the first filter hole 1021 and the second filter hole 301 are not provided at the bottom ends of the filter cover plate 102 and the movable cover plate, respectively.
[0048] The roof gutter fixing device described above is mounted on the roof of a corresponding building, and the corresponding drainage pipeline is connected to the drainage pipe of the present invention to drain the water in the drainage ditch in time.
[0049] The specific usage process is as follows:
[0050] 1) On sunny days, leaves and other debris are filtered and blocked outside the drainage ditch 101 by the filtering cover 102 and the movable cover 3;
[0051] 2) On rainy days, rainwater enters the drainage ditch 101 through the filter cover 102 and the first filter hole 1021 and the second filter hole 301 of the movable cover 3, flows along one end of the drainage ditch 101 where the drainage pipe 2 is provided, and is then discharged along the drainage pipe 2;
[0052] 2.1) When the water level flowing through the drainage ditch 101 does not exceed the height of the end of the water retaining plate 401 away from the drainage pipe 2, the rainwater flows along the water retaining plate 401 and the bottom of the drainage ditch 101. At this time, debris such as leaves will not enter the drainage ditch 101;
[0053] A small amount of debris such as leaves that enter the drainage groove 101 is effectively filtered by the hemispherical filter cover 501 of the drainage filter device 5, so as to prevent debris such as leaves from entering the drainage pipeline when the water flow rate / water flow pressure is insufficient, thereby eventually causing the pipeline to be blocked;
[0054] 2.2) When the water level flowing through the drainage groove 101 exceeds the height of the end of the water retaining plate 401 away from the drainage pipe 2, the water flow forms pressure on the end of the water retaining plate 401 away from the drainage pipe 2, and the end of the water retaining plate 401 away from the drainage pipe 2 is forced to swing downward, and the elastic member 403 is compressed until the water retaining plate 401 is pushed as a whole until the end away from the drainage pipe 2 abuts against the bottom surface of the drainage groove 101. At this time, rainwater flows along the upper side of the water retaining plate 401;
[0055] 2.3) The installation height of the movable cover plate 3 decreases as the water retaining plate 401 moves downward, so that the movable cover plate 3 and the filter cover plate 102 are spaced apart. At this time, part of the rainwater enters the drainage ditch 101 through the first filter hole 1021 of the filter cover plate 102, while part of the rainwater flows directly through the bottom of the filter cover plate 102 to the space between the filter cover plate 102 and the movable cover plate 3 and directly enters the drainage ditch 101;
[0056] At this time, under the action of the annular float 503, the drainage filter device 5 floats as a whole, thereby effectively and significantly increasing the filtering area, so as to quickly increase the water flow entering the drain pipe 2, and effectively increase the filtering interval, so that leaves and other debris can enter the drain pipe 2 between two adjacent limiting rods 502. Since the water flow / water flow pressure is large at this time, leaves and other debris can be effectively flushed out of the drainage pipe to prevent the drainage pipe from being blocked.
[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
