Description

High-speed diversion and drainage device with sedimentation function

The present invention belongs to the technical field of outdoor drainage. Specifically, it is a high-speed diversion drainage device with a sedimentation function, which can prevent sediment from accumulating in the drainage pipe and prevent garbage, fallen leaves and other debris from falling into the drainage pipe, and can have the effects of anti-clogging and rapid diversion.

According to the regulations, in order to avoid water accumulation after rain or watering, drainage pipes are usually planned on the roofs of buildings or outdoor places such as gardens, and multiple drainage devices (also known as downspouts) connected to the drainage pipes are installed on the floor or ground to reduce the invasion of foreign objects into the drainage pipes and affect drainage. Most of the aforementioned places have debris such as mud, gravel, fallen leaves, dead branches or garbage. When encountering abnormal rainfall such as heavy rain, torrential rain, or extremely heavy rain, a large amount of water flow will carry debris such as fallen leaves, dead branches or garbage, and quickly block the drainage devices, causing them to be unable to discharge the accumulated water smoothly;

Therefore, some drainage devices are equipped with high-legged cages protruding from the ground and with holes on all sides to prevent debris in the large water flow from covering and clogging the drainage device and affecting the drainage function. However, although the aforementioned drainage device can block larger debris such as fallen leaves, dead branches or garbage, it cannot block mud or gravel that is much smaller than the holes, regardless of the size of the water flow. Therefore, mud and sand will flow into the drainage pipe with the water flow, and these mud and sand will accumulate in the drainage pipe, causing the drainage pipe to be blocked.

Therefore, the existing drainage devices used to connect drainage pipes in outdoor places are still not perfect in design, and cannot effectively produce the barrier and purification effects, and at the same time have the effect of rapid diversion. Therefore, the existing drainage devices do need to be further improved, which is also the topic that this invention intends to explore.

Due to the above shortcomings and needs, the inventor has used his many years of experience in related technologies and product design and manufacturing to study the above shortcomings and needs, and actively seek solutions. After continuous efforts in research and trial production, he finally successfully developed a high-speed diversion and drainage device with a sedimentation effect to overcome the troubles caused by the exposed brake group and the inconvenience of grip adjustment in the existing hydraulic brake system.

Therefore, the main purpose of the present invention is to provide a high-speed diversion drainage device with a sedimentation function, which can be installed on roofs and outdoor places such as gardens, and can effectively precipitate fine mud and sand during drainage, and purify impurities in the water flow. At the same time, it is easy to clean, so as to reduce the clogging of drainage pipes and make drainage smoother.

In addition, the second main purpose of the present invention is to provide a high-speed diversion drainage device with a sedimentation function, which can effectively prevent garbage, fallen leaves and other debris from falling into the drainage pipe in heavy rain and other large water flow conditions to avoid blockage, and can accelerate the drainage speed, effectively improving its practicality.

Based on this, the present invention mainly realizes the aforementioned purpose and its effect through the following technical means, and is provided for connecting a drainage pipe, which includes:

A base, which has a discharge pipe connected to the drainage pipe at the bottom, a sand collecting space is formed between the base and the lower section of the discharge pipe, and the discharge pipe has a plurality of overflow holes formed above the sand collecting space, and the upper section of the base has an annular baffle wall, and the annular baffle wall has a plurality of water permeable holes, and the inner edge of the annular baffle wall has a vertical sleeve, the sleeve has a convex baffle portion higher than the annular baffle wall, and the bottom end of the sleeve has a bearing portion lower than the discharge pipe;

A high-legged cage is provided with a plurality of fast flow grooves formed on its periphery, and the bottom of the high-legged cage has a carrier plate extending outward horizontally, and the carrier plate is provided with a plurality of water seepage holes, so that the high-legged cage can be stacked on the lining sleeve of the base using the carrier plate, and a stone-filling space is formed between the high-legged cage and the lining sleeve for filling with gravel.

Thus, the high-speed diversion drainage device with sedimentation function of the present invention can utilize the sand collection space at the bottom of the base, and cooperate with the loading plate of the high-legged cage to form a stone filling space, so that low-flow or medium-flow water can first be precipitated in the sand collection space before being discharged, which can produce the effect of blocking mud and sand to reduce the phenomenon of siltation in the drainage pipe. At the same time, when encountering high flow, it can be directly discharged from the fast flow groove on the high-legged cage to reduce the phenomenon of water accumulation on the roof or garden, so that it can have the effects of sedimentation, purification and rapid diversion, and can easily clean the mud and sand deposited in the sand collection space to ensure its mud and sand blocking effect, greatly improve its practicality, and realize its economic benefits.

The present invention also utilizes the following technical means to further achieve the aforementioned purposes and effects; such as:

Preferably, the bottom surface of the base has a connecting pipe connected to the drain pipe, and the connecting pipe has an inner joint surface and an outer joint surface, which can be used to connect to drainage pipes of different diameters.

Preferably, the base has a ring abutment formed at the top of the inner edge of the corresponding pipe for the connected drainage pipe to abut against.

Preferably, the inner edge of the sand collecting space of the base forms a tapered edge that converges downward to enhance the sand collecting effect.

Preferably, the annular retaining wall of the base has a vertical section protruding upward and a horizontal section protruding inward, and the water-permeable holes are formed in at least one of the vertical section and the horizontal section.

Preferably, the carrier plate of the high-legged cage has a baffle that can abut against the inner edge of the aforementioned base liner, so that the gravel in the stone-filling space can be easily removed.

Preferably, the inner edge of the high-legged grille has a series of convex rings corresponding to the top of the discharge pipe, so that the high-legged grille can be stably stacked on the base using the carrier.

Preferably, both or one of the discharge pipe and the annular baffle of the base can be a modular structure to facilitate model manufacturing of parts.

Preferably, when the base and the annular retaining wall are separate assembled structures, the top edge of the base has a first engaging portion, and the bottom edge of the annular retaining wall has an opposite second engaging portion, so that the base and the annular retaining wall can be connected by the first and second engaging portions facing each other.

Preferably, the base and the high-legged cage may have a circular outline.

In order to enable the review committee to further understand the structure, features and other purposes of the present invention, the following are some preferred embodiments of the present invention, and are described in detail with the help of drawings, so that those familiar with the technical field can implement them in detail.

The present invention is a high-speed diversion and drainage device with a sedimentation function. In the specific embodiments of the present invention and its components illustrated in the attached drawings, all references to front and back, left and right, top and bottom, upper and lower, and horizontal and vertical are only used for the convenience of description and do not limit the present invention or its components to any position or spatial direction. The dimensions specified in the drawings and the specification can be changed according to the design and requirements of the present invention without departing from the scope of the patent application of the present invention.

As shown in the first, second and third figures, the high-speed diversion and drainage device with a sedimentation function of the present invention is applied to an outdoor place such as a roof or a garden, and has a base (10) and a high-legged cage (20) installed on the base (10);

The base (10) is provided with a discharge pipe (11) in the center. The discharge pipe (11) is provided with a plurality of overflow holes (12) penetrating inside and outside above the middle section. The overflow holes (12) can be circular holes or strip holes, so that a sand-catching section (110) is formed at the lower section of the discharge pipe (11). The discharge pipe (11) has a connecting pipe (13) protruding from the bottom surface of the base (10), wherein the connecting pipe (13) has an inner joint surface (131) and an outer joint surface (132) can be used to connect to drainage pipes (50) of different diameters (as shown in the third figure). For example, the base (10) can use the inner joint surface (131) of the connecting pipe (13) to connect to the outer edge of an existing 2-inch pipe, or can use the outer joint surface (132) of the connecting pipe (13) to connect to the inner edge of an existing 3-inch pipe, and the discharge pipe (11) has a ring abutment (135) formed on the inner edge of the top end of the corresponding connecting pipe (13) for the connected drainage pipe (50) to abut against;

The lower section of the base (10) has a sand collecting space (14) corresponding to the sand holding section (110) of the discharge pipe (11). The sand collecting space (14) can form a tapered edge (140) that converges downward to improve the sand collecting effect. The upper section of the base (10) has an annular retaining wall (15), and the annular retaining wall (15) has a vertical section (16) protruding upward and a horizontal section (17) protruding inward. A plurality of water-permeable holes (150) are formed, and the water-permeable holes (150) can be circular holes or strip holes. Furthermore, the inner edge of the horizontal section (17) of the annular baffle wall (15) has a vertical lining (18), and the lining (18) has a convex stopper (181) higher than the surface of the horizontal section (17), and the bottom of the lining (18) has a bearing portion (182) slightly lower than the discharge pipe (11) for the aforementioned high-legged cage ( 20) is provided; and the high-legged grille (20) is formed with a plurality of fast flow grooves (21) for quickly diverting rainwater, and the bottom of the high-legged grille (20) is provided with a carrier plate (25) extending horizontally outward, and the carrier plate (25) is provided with a plurality of water seepage holes (26), and the carrier plate (25) of the high-legged grille (20) is provided with a baffle (27) that can abut against the inner edge of the lining (18) of the aforementioned base (10), and the high-legged grille (20) The inner edge has a series of convex ring pieces (22) corresponding to the top of the discharge pipe (11), so that the high-legged cage (20) can be stably stacked on the supporting part (182) of the lining (18) of the base (10) by using the carrier plate (25), and a stone filling space (28) is formed between the high-legged cage (20) and the lining (18) of the base (10) for filling with gravel (30) during installation (as shown in the fourth figure) to block leaves and purify water flow.

Thus, the annular retaining wall (15) with the water-permeable hole (150) on the base (10) and the carrier plate (25) with the water-permeable hole (26) on the carrier plate (25) can produce a barrier and purification effect, while the fast flow groove (21) of the high-legged cage (20) also has a rapid diversion effect, thereby forming a high-speed diversion and drainage device with a sedimentation effect.

As for the actual use of the high-speed diversion and drainage device with a sedimentation function of the present invention, as shown in the third and fourth figures, in terms of operation, the base (10) is buried in the roof floor or garden lawn, so that the floor or lawn surface is equal to or slightly lower than the horizontal section (17) of the annular retaining wall (15) of the base (10), and at the same time, the connecting pipe (13) at the bottom of the base (10) is connected to the corresponding drainage pipe (50), and the high-legged cage (20) is placed on the supporting part (182) of the lining (18) of the base (10) with a carrier (25), and the crushed stone (30) is laid in the stone filling space (28) between the high-legged cage (20) and the lining (18);

Thus, when a small flow of water such as watering or light rain is encountered, as shown in the fourth figure, the water can slowly flow from the water permeable holes (150) on the annular retaining wall (15) of the base (10) into the sand collecting space (14) of the base (10), so that the mud and sand contained in the water can be precipitated in the sand collecting space (14), and when the water flow height in the sand collecting space (14) exceeds the sand retaining section (110) of the discharge pipe (11) in the base (10), the water can flow from the overflow hole (12) on the discharge pipe (11) to the drainage pipe (50) connected to the bottom of the base (10), so that the mud and sand can be blocked to reduce the clogging of the drainage pipe. When it is necessary to clean the mud and sand deposited in the sand collecting space (14) of the base (10), it is only necessary to slightly clean the gravel (30) on the carrier (25) of the high-legged cage (20) and take the high-legged cage (20) upwards, so that the mud and sand deposited in the sand collecting space (14) can be directly excavated to ensure its effectiveness in blocking mud and sand.

When encountering a medium flow of water during a heavy rain, as shown in FIG. 5 , the water will not only flow from the water permeable holes (150) on the annular retaining wall (15) of the base (10) into the sand collecting space (14) of the base (10), so that the mud and sand contained in the water flow can be precipitated in the sand collecting space (14), but also when the water flow height exceeds the convex stop (181) of the liner (18) of the base (10) and enters the gravel (30) area of the stone filling space (28), the gravel (30) can be used for purification. The water can be used to block leaves, etc., and the purified water can flow into the sand collecting space (14) from the seepage holes (26) on the carrier plate (25) of the high-legged cage (20). Once the water flow height in the sand collecting space (14) exceeds the sand-blocking section (110) of the discharge pipe (11) in the base (10), the water can quickly flow from the overflow hole (12) of the discharge pipe (11) to the drainage pipe (50) connected below, thereby producing the effect of blocking mud and sand and purifying, thereby reducing the phenomenon of silting in the drainage pipe.

Furthermore, when encountering a high flow of water at the level of heavy rain, as shown in FIG. 6, at this time, the principle of rapid diversion is adopted. In addition to flowing into the sand collecting space (14) through the water permeable holes (150) on the annular retaining wall (15) of the base (10) and the water seepage holes (26) on the carrier plate (25) of the high-legged cage (20), the water flow is quickly discharged into the drainage system through the overflow hole (12) of the discharge pipe (11). In addition to the pipe (50), it will further be directly flushed into the inside of the discharge pipe (11) of the base (10) through the fast flow groove (21) on the high-legged fence (20), and quickly discharged from the drainage pipe (50) to reduce the phenomenon of water accumulation on the roof or garden. At the same time, the high-legged fence (20) can effectively prevent debris such as leaves and garbage from falling into the drainage pipe in the water flow to avoid blockage, thereby ensuring the speed of drainage.

The present invention also has different embodiments. As shown in FIG. 7 , the discharge pipe (11) and the annular baffle (15) of the base (10) or one of them may be a modular structure to facilitate model manufacturing of parts. If the annular baffle (15) and the base (10) are a separate modular structure, the top edge of the base (10) has a first engaging portion (100), and the bottom edge of the annular baffle (15) has an opposite second engaging portion (155), so that the base (10) and the annular baffle (15) can be connected by the first and second engaging portions (100, 150) being oppositely covered. As shown in Figure 8, the base (10) and the high-legged cage (20) may have a circular outline or a rectangular outline to match different locations and environments of the roof or garden.

Through the above-mentioned design and description, the high-speed diversion and drainage device with a sedimentation function applied to outdoor places of the present invention can utilize the sand collecting space (14) at the bottom of the base (10), and cooperate with the carrier plate (25) of the high-legged cage (20) to form a stone filling space (28), so that low-flow or medium-flow water can flow from the water-permeable holes (150) of the annular retaining wall (15) of the base (10) or the water-permeable holes (26) of the carrier plate (25) of the high-legged cage (20) into the sand collecting space (14) for sedimentation and then discharge. This can block mud and sand to reduce the clogging of the drainage pipe. At the same time, when there is a high flow rate, the fast flow groove (21) on the high-legged cage (20) can directly flush into the discharge pipe (11) of the base (10) and be quickly discharged from the drainage pipe (50) to reduce the phenomenon of water accumulation on the roof or garden. At the same time, the high-legged cage (20) can effectively prevent leaves and garbage from falling into the drainage pipe to avoid clogging, so that it can have the effects of sedimentation, purification and rapid diversion;

At the same time, when it is necessary to clean the mud and sand deposited in the sand collecting space (14) of the base (10), it is only necessary to slightly clean the gravel (30) on the carrier (25) of the high-legged cage (20) and take the high-legged cage (20) upwards. In this way, the mud and sand deposited in the sand collecting space (14) can be directly excavated to ensure its effectiveness in blocking mud and sand, and it is convenient to clean, greatly improving its practicality.

From this, we can understand that this invention is a very creative creation. In addition to effectively solving the problems faced by practitioners, it also greatly improves the efficacy. In the same technical field, there is no same or similar product creation or public use. At the same time, it has improved efficacy. Therefore, this invention has met the requirements of invention patents regarding "novelty" and "progressiveness", and an invention patent application is filed in accordance with the law.
