[0001] The utility model relates to the technical field of house drainage, in particular to a gravity overflow rainwater bucket. Background Art

[0002] The rain gutter is mainly composed of an inlet, an outlet and connecting parts. The inlet part is used to receive rainwater from the roof, and the outlet part guides the rainwater to the underground drainage pipe. The connecting parts usually include flanges and bolts, which are used to fix the rain gutter on the roof. When rainwater falls on the roof, it flows into the rain gutter along the slope of the roof. The design of the rain gutter allows the water to flow smoothly from the inlet to the outlet and finally into the underground drainage pipe. In this process, the rain gutter plays the role of collecting and guiding rainwater.

[0003] In the roof drainage system of a building, rainwater needs to be effectively collected and discharged to avoid water accumulation causing damage to the building or leakage. Traditional rain gutters can usually only handle a certain amount of rainwater. When the rainfall exceeds its capacity, it may cause water to overflow and affect the normal use of the building. Currently, construction is often done by setting a circle of cofferdams outside the rain gutters. When set inside the gutter, it often affects the collection of rainwater.

[0004] In the related art, when a large amount of rainwater pours into the rain gutter, the technical problem that the traditional rain gutter cannot discharge the rainwater has not yet been effectively solved. Utility Model Content

[0030] Example

[0031] Reference Figure 1-Figure 3 , is a gravity overflow rainwater bucket disclosed by the utility model, which includes: a guide component and a water pipe 6, the guide component is internally connected to the inside of the water pipe 6, and the guide component is clamped with the water pipe 6; the guide component includes a guide cover 1, an overflow plate 3 and a positioning column 5, a pressure plate 2 is arranged between the guide cover 1 and the overflow plate 3, the guide cover 1 is fixedly connected to the upper part of the pressure plate 2, and the overflow plate 3 is fixedly connected to the lower part of the pressure plate 2.

[0032] The flow guide assembly is embedded in the water pipe 6, the water pipe 6 is sleeved on the positioning column 5 of the flow guide assembly, an overflow plate 3 is sleeved on the outside of the positioning column 5, a pressure plate 2 is fixedly connected to the top of the overflow plate 3, a flow guide cover 1 is fixedly connected to the top of the pressure plate 2, and the flow guide cover 1 is also sleeved on the outside of the positioning column 5. The water pipe 6 is made of stainless steel, galvanized steel or other corrosion-resistant materials.

[0033] Specifically, when the roof needs to be drained, rainwater will flow into the rain gutter and enter the water pipe 6 for discharge. When the rain is too heavy, the rainwater will flow back along the water pipe 6 and overflow from the rainwater inlet of the rain gutter. However, when there is too much rain, the traditional rain gutter will be submerged and the rainwater cannot be discharged in reverse flow. Therefore, in the traditional technology, the height of the rain gutter is increased by additionally installing a cofferdam so that the rainwater can overflow in reverse flow when it is too heavy. The utility model increases the height of the guide cover 1 by the overflow plate 3, so that it itself has the same function as the cofferdam, and there is no need to spend manpower to install an additional cofferdam, which provides convenience for workers and increases installation efficiency.

[0034] The utility model can be installed on the top of any building, especially on a roof with a rain gutter, and will not affect the convergence of rainwater. When there is too much rain, the traditional rain gutter will be submerged, but the utility model effectively prevents the rain gutter from being submerged and causing the rainwater on the roof to be unable to be discharged by increasing the height of the deflector 1. Through effective drainage, it is possible to prevent excessive water accumulation on the roof and damage to the roof structure. The use of a water pipe 6 made of corrosion-resistant material can increase the service life of the rain gutter.

[0035] In an optional embodiment, the outer diameter of the positioning column 5 is the same as the inner diameter of the water pipe 6, and the water pipe 6 is sleeved on the outer side of the positioning column 5. Since the positioning column 5 and the water pipe 6 are tightly sleeved, a more stable structure can be provided, reducing the possibility of displacement or deformation. The outer diameter of the positioning column 5 is the same as the inner diameter of the water pipe 6, making the installation process simpler and faster. This design can ensure that the water pipe 6 and other components can be connected to each other and have interchangeability. This structure can better protect the pipeline and avoid damage caused by external force or improper installation.

[0036] In an optional embodiment, the deflector 1 includes at least two grilles, which are fixedly connected to the pressure plate 2, and the gap between the two grilles allows rainwater to flow in or out. The deflector 1 is sleeved on the outside of the positioning column 5, and the side of the grille close to the axis of the water pipe 6 abuts against the outside of the positioning column 5. Generally, multiple grilles are provided, but the distance between the grilles should be ensured not to affect drainage.

[0037] Specifically, since the deflector 1 and the positioning column 5 are tightly connected, a more stable structure can be provided, reducing the possibility of displacement or deformation. This design makes the installation process simpler and faster, and also facilitates subsequent maintenance and repair. The design of the grille can effectively reduce the impact of rainwater on the pipe and improve drainage efficiency. With this design, there is no need to use additional seals, thereby saving material costs. This structure can adapt to various environments and working conditions, and has strong versatility and portability.

[0038] In an optional embodiment, the overflow plate 3 is a cylinder, the diameter of the through hole at the bottom of the overflow plate 3 is the same as the outer diameter of the positioning column 5, and the diameter of the through hole at the top of the overflow plate 3 is the same as the diameter of the air deflector 1. The overflow plate 3 is sleeved on the outside of the positioning column 5, and the through hole at the bottom of the overflow plate 3 is sleeved on the positioning column 5. The overflow plate 3 serves to increase the height of the air deflector 1.

[0039] Specifically, by sleeve-connecting the overflow plate 3 on the outside of the positioning column 5, the height of the deflector 1 can be effectively increased, so as to better deal with the problem of excessive rainwater flow. When the amount of rainwater is too much, the overflow plate 3 can discharge the excess rainwater from a higher position to avoid overloading or excessive pressure on the system. The overflow plate 3 can prevent pressure fluctuations or water hammer caused by unstable water flow. Since the design of the overflow plate 3 takes into account the direction and speed of the water flow, it also helps to reduce the impact force of the water flow on the pipes and equipment, thereby protecting these key components from damage. This can not only extend the service life of the equipment, but also reduce maintenance costs. The design of the overflow plate 3 is simple and clear, making installation and maintenance relatively easy. At the same time, it has high elasticity and a low operating lower limit, so that it can maintain good performance under different working conditions. The design of the overflow plate 3 not only improves the efficiency and stability of the drainage system, but also enhances the safety and durability of the equipment.

[0040] In an optional embodiment, the fixing bolt 4 connects the air deflector 1, the pressure plate 2 and the overflow plate 3, and the fixing bolt 4 is perpendicular to the pressure plate 2. The top of the air deflector 1 is fixedly connected with a protective net 7, the protective net 7 is fixedly connected with the pressure plate 2, and the protective net 7 covers the air deflector 1. The outer side of the water pipe 6 is sleeved with a baffle 8. The diameter of the pressure plate 2 is larger than the diameter of the air deflector 1; the diameter of the top of the baffle 8 is larger than the diameter of the air deflector 1.

[0041] Specifically, through the vertical connection of the fixing bolts 4, the tightness between the air deflector 1, the pressure plate 2 and the overflow plate 3 can be enhanced, thereby improving the stability of the system. At the same time, since the diameter of the pressure plate 2 is larger than the diameter of the air deflector 1, and the top diameter of the baffle 8 is larger than the diameter of the air deflector 1, this design can further improve the stability of the drainage system. The fixing bolts 4 have a simple structure and are easy to operate, and installation and maintenance work can be completed without too many tools. In addition, when a component needs to be replaced, the bolts can also be easily removed for replacement. The connection of the fixing bolts 4 can effectively prevent the components from falling off due to vibration or impact, thereby protecting the equipment from damage. At the same time, the setting of the baffle 8 can prevent the impact of water flow on the side wall of the equipment and extend the service life of the equipment. By fixing the protective net 7 on the top of the air deflector 1, foreign matter can be prevented from entering the system to ensure the normal operation of the equipment.

[0042] The utility model raises the deflector 1 by installing the overflow plate 3, so that the height of the deflector 1 is increased, and the height of the water inlet of the rainwater bucket is increased. When the rainwater is too heavy, the rainwater bucket of the utility model can still discharge the rainwater in reverse flow. In addition, the utility model is suitable for installation on any roof form, especially on roofs with rainwater ditches, and will not affect the convergence of rainwater. There is no need to install additional cofferdams during installation, making the installation easier, reducing manpower and improving the installation efficiency. A protective net 7 is installed on the top to prevent foreign objects from falling into the water pipe 6 and causing the water pipe 6 to be blocked.

[0043] The working principle and beneficial effects of the utility model are:

[0044] The gravity overflow rainwater bucket of the utility model is suitable for installation on any roof form, whether it is a flat roof, a pitched roof or other special shaped roofs, it can be easily installed and used. Especially for roofs with rainwater gutters, the gravity overflow rainwater bucket of the utility model will not affect the normal convergence of rainwater, ensuring the normal operation of the drainage system.

Even in the case of heavy rain or strong wind, it can maintain a stable drainage effect, avoiding drainage system failure caused by water flow impact. The gravity overflow rainwater bucket of the utility model is equipped with a protective net 7, which can effectively filter out the debris and particulate matter flowing into the bucket body, and improve the cleanliness of the bucket body. This can not only reduce the possibility of blockage of the bucket body, but also extend the service life of the bucket body, reducing the maintenance and cleaning work. The gravity overflow rainwater bucket of the utility model has obvious advantages in installation applicability, stability and reliability, and cleanliness. It can not only meet the installation requirements of different roof forms, but also ensure the stability and reliability of the system, while improving the cleanliness of the bucket body, providing users with a more convenient, efficient and reliable drainage solution. In general, the utility model realizes the function of overflow rainwater bucket by increasing the height of the deflector 1, without the need to install additional cofferdams, improving construction efficiency, and saving manpower and material costs.
