Detailed Description

The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings and specific embodiments for further understanding the objects, aspects and functions of the present invention, but not for limiting the scope of the appended claims.

As shown in fig. 1 and fig. 2, fig. 1 is the structural schematic diagram of an embodiment of the switching well in the roof rainwater, fig. 2 is the structural schematic diagram of the switching well in the roof rainwater and the relation of the building connection position. The utility model discloses a well 10 is connect in disconnected in roofing rainwater sets up in the ground 30 in the building 20 outside. The ground 30 may be, for example, a green space, a brick space, or the like outside the building 20.

As shown, the building 20 includes a roof gutter 21, the roof gutter 21 extending all the way to the ground through a pipe. The roof rainwater transfer well 10 comprises a main body well wall 100 and a water inlet 200, wherein the main body well wall 100 is vertically arranged, and can be a hollow cylinder with a circular or square cross section and arranged vertically. The main well wall 100 is partially located above the ground 30 and partially embedded below the ground 30, and in detail, the main well wall 100 includes a side wall 110, and the side wall 110 includes an underground wall 111 embedded below the ground 30 and an underground wall 112 located above the ground 30, that is, the underground wall 111 of the side wall 110 is located underground, and the underground wall 112 of the side wall 110 is exposed above the ground. The water inlet 200 is connected to the underground wall 111 of the sidewall 110, wherein the water inlet 200 of the switching well 10 for roof rainwater of the present invention is communicated with the roof rainwater hopper 21 of the building 20. It can be seen that roof rainwater from the building 20 is directed to the ground through the roof rainwater hopper 21 and discharged into the trunk 10 through the water inlet 200. Through the utility model discloses make 20 roof rainwater on building not directly enter the rainwater drain pipe network system that 20 outer buries of building, but pass through the utility model discloses a 10 infiltration overflows and gets into ground 30 or rainwater drain pipe network system after the disconnection in the roofing rainwater, can increase the flow time of rainwater on ground, reduce the rainwater runoff peak value, realize the delay of rainwater, reduce the possibility that urban waterlogging appears.

As shown in fig. 1, the main well wall 100 further includes a well lid 130, the well lid 130 being movably connected to the top of the upper ground wall 112 of the side wall 110. The well lid 130 is in a closed state during daily use, and can be opened as required when the well body needs to be overhauled or the water discharge is too large.

Wherein, the vertical distance between the highest position of well lid 130 to the lowest position of the well head wall 111 of lateral wall 110 is 100 to 200mm, promptly the utility model discloses a total overground part's of well 10 is disconnected in roofing rainwater height is suitable at 100 to 200 mm.

The utility model discloses an embodiment, the main body wall of a well 100 still includes at least one overflow mouth 140, and overflow mouth 140 sets up in the outside of ground upper wall 112 to well lid 130 is higher than overflow mouth 140, and overflow mouth 140 for example is a plurality of along the even setting in the outside of ground upper wall 112.

The roof rainwater of the building 20 enters the shaft through the underground water inlet 200 for temporary storage and transfer, and when the rainfall is small, the rainwater temporarily stored in the shaft cannot overflow and slowly seeps into the underground. As the amount of rain increases, the height of the rainwater gradually rises above the ground, and at this time, the rainwater overflows to the ground 30 through the plurality of overflow ports 140 provided on the outer side of the ground upper wall 112. The utility model discloses a roofing rainwater is derived to the mode of overflow, does not produce to erode and splash ground 30, can not influence the pedestrian current because of the downspout meets absolutely.

The above-ground wall 112 has a communication hole 112a for communicating the overflow port 140, and when the roof rainwater in the well rises to a certain height, the rainwater flows to the overflow port 140 through the communication hole 112a to overflow. The overflow port 140 includes a first outflow port 141, and the first outflow port 141 is a horizontal outlet, so that roof rainwater does not generate scouring force on the ground 30 when overflowing from the first outflow port 141. Further, in other embodiments, the overflow port 140 further includes a second outlet 142, and the second outlet 142 is a vertical outlet or an inclined outlet, which can further increase the overflow flow. In practical implementation, the second outflow port 142 may be controlled, for example, the second outflow port 142 is opened by resistance, and the second outflow port is opened when the water flow is too large and exceeds a certain pressure, so that unnecessary washing of the ground 30 by the water flow is avoided, and it is ensured that a large flow is generated during heavy rain and the second outflow port can still be used normally.

Preferably, the overflow port 140 is provided with a filtering device 143 for filtering out impurities such as leaves, etc., and the impurities such as leaves staying in the well can be manually opened to clean the well lid 130 at regular time, so as to prevent the impurities from blocking the overflow port 140.

The utility model discloses a well 10 is connect absolutely in roofing rainwater still including setting up in the purifier 300 of the bottom of the main part wall of a well 100 to purifier 300 is located the position that sets up below the water inlet 200 on lateral wall 110, avoids purifier 300 to influence the speed of the ascending overflow of rainwater in the well.

Wherein, purifier 300 is full of the bottom of main part wall of a well 100, and the interior rainwater permeates downwards after passing through purifier 300 filtration, as the replenishment of groundwater.

The water purifying device 300 is, for example, a bag type water purifying device, and may adopt a structure of a ceramsite type filtering layer and a dirt absorbing sponge ball filtering layer which are stacked, the movable water purifying device 300 is convenient for cleaning, management and maintenance, and has excellent water purifying effect. Of course, in the area with clean air, the roof cleanliness is high, the initial rainwater pollutants are few, and the arrangement can be omitted.

As shown in fig. 2, the centerline of the main well wall 100 has a shortest horizontal distance with the outer wall of the building 20, and the shortest horizontal distance is greater than or equal to 5 m.

The utility model discloses a roofing rainwater transit make-up well 10 has infiltration, overflow and make-up function absolutely, and the bottom that the rainwater passes through roofing rainwater make-up well 10 absolutely effectively to secret infiltration, for the groundwater moisturizing, and has the function of effect detach pollutant. And secondly, the redundant initial rainwater enters the ground 30 through overflow and has the function of preventing the rainwater from directly washing the ground.

The utility model discloses a roof rainwater transfer disconnected well 10 can effectively increase the time of converging on ground of roof rainwater, delays the time of arriving at the rainwater peak value, and the effective volume of rainwater infiltration overflow disconnected well is being 1m ³ To 2.5m ³ Can collect 5mm initial rainwater on the roof and meet the requirement of 200m service area of a rainwater hopper ² To 500m ² When the drainage area of the rain hopper is large, the effective volume of the rain hopper can be properly increased.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
