Description

Technical Field

[0001] The utility model relates to the field of building drainage design, in particular to a building rainwater riser disconnection and connection energy dissipation device. Background Art

[0002] Disconnecting building rainwater risers is an important and common technology in sponge city construction. When setting up source emission reduction facilities in green areas around buildings, building rainwater risers are usually disconnected. After energy dissipation treatment, they are connected to source emission reduction facilities to store and treat rainwater and then discharge it as overflow.

[0003] Due to the increasingly high requirements for building facade landscape, residential and public buildings gradually install rainwater risers on the inside of the wall, which makes it much more difficult to disconnect than rainwater risers installed outside the wall. In addition, due to the high floors, in order to prevent the excessive flow rate of water in the riser from eroding the plants and soil in the source reduction facilities, special facilities are required to dissipate energy to reduce the flow rate of rainwater. At present, the disconnection and dissipation of rainwater risers in high-rise buildings generally have defects such as complex process, high cost and poor effect. Utility Model Content

[0022] Reference Figures 1 to 3 A building rainwater riser disconnect energy dissipation device includes a trough body 10 and an energy dissipation plate 20. The trough body 10 includes a mounting plate 11, a bottom plate 12, a side plate 13 and a vertical panel 14. The mounting plate 11 is fixedly arranged on the outer wall of the building. The rainwater riser is inserted in the mounting plate 11. The water outlet of the rainwater riser is connected to the trough body 10. The lower end of the vertical panel 14 is close to the rainwater riser, and the upper end is away from the rainwater riser. The energy dissipation plate 20 is arranged in the trough body 10. The energy dissipation plate 20 is in contact with a side of the vertical panel 14 close to the rainwater riser.

[0023] It can be understood that the lower end of the vertical panel 14 is close to the rainwater riser, and the upper end is far away from the rainwater riser. When the water in the rainwater riser is discharged into the trough body 10, it first hits the energy dissipation plate 20 attached to the inclined vertical panel 14. The equally inclined energy dissipation plate 20 can guide the rainwater upward and then bounce back to the side of the mounting plate 11, thereby reducing the rainwater flow rate and achieving rainwater energy dissipation.

[0024] It is worth noting that, in some embodiments of the present invention, at least two drainage holes 121 are formed on the bottom plate 12 .

[0025] It is worth noting that, in some embodiments of the present invention, at least two drainage holes 121 are formed on the bottom plate 12 , and the two drainage holes 121 are respectively formed near the two side plates 13 .

[0026] It is worth noting that when the rain is not heavy, drainage can be achieved through the drainage hole 121.

[0027] Reference Figure 3 The energy dissipation plate 20 includes a straight plate section 21 and a curved plate section 22. The straight plate section 21 is in contact with the vertical panel 14. The curved direction of the curved plate section 22 is close to the rainwater riser.

[0028] It can be understood that the arc plate segment 22 can further guide the rainwater to flow back to one side of the mounting plate 11 to counteract and dissipate energy with the water flow just discharged from the rainwater riser.

[0029] Reference Figure 3 and Figure 4 , and also includes a guide plate 30. The guide plate 30 is covered on the trough body 10. The rainwater riser is located below the guide plate 30, and a plurality of guide holes 31 are opened on the guide plate 30.

[0030] It is worth noting that when the rain is too heavy, the guide plate 30 can prevent the rain from splashing, so that the water level in the trough body 10 rises slowly, then seeps upward through the guide holes 31 and flows out from the side plate 13.

[0031] Reference Figure 3 and Figure 4 The guide plate 30 is also provided with a drainage end 32. The drainage end 32 is arranged on the side of the guide plate 30 away from the rainwater riser. The drainage end 32 is higher than the two sides of the guide plate 30 close to the two groups of side plates 13. Rainwater flows out preferentially from the two sides of the guide plate 30 close to the two groups of side plates 13.

[0032] It is understandable that in order to prevent the rainwater from falling too far away from the building after being discharged from the facade panel 14 , the drainage end 32 is used to prevent the rainwater from flowing toward the facade panel 14 and then flowing out from the two sets of side panels 13 .

[0033] It should be noted that the utility model of a building rainwater riser disconnection and energy dissipation device has the following working conditions:

[0034] Operation condition 1: Normal rainfall operation condition. Under normal rainfall, rainwater from the building rainwater riser enters the trough 10. After the flow rate is reduced by the energy dissipation plate 20, the water level in the trough 10 slowly rises, passes through the guide hole 31 on the guide plate 30 to the top of the trough 10, and then is led to the two side plates 13 through the drainage end 32 for uniform distribution. After the rainfall ends, the accumulated rainwater in the trough 10 is continuously drained through the drainage hole 121 on the bottom plate 12, thereby realizing the normal operation of the energy dissipation facility.

[0035] Operation condition 2: Extreme rainstorm operation condition. When the rainfall exceeds the standard and the rainfall is too heavy, exceeding the load of the energy dissipation facility, the guide plate 30 can be opened to increase the water flow rate, thereby achieving the normal operation of the energy dissipation facility.

[0036] Operation condition three: light rain operation condition. In light rain, the rainfall is too small, and the water level in the trough body 10 cannot reach the trough top. At this time, the flow rate of rainwater is also low, and it can be discharged through the drainage holes 121 of the bottom plate 12, and the energy dissipation facility can operate normally.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
