Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
The rainwater drainage system is mainly arranged in a road rainwater pipe network, and particularly as shown in figure 1, a rainwater drainage pipeline 12 is arranged on a boundary structure of a rainwater well 11 and is connected with a municipal rainwater pipe network, the rainwater well 11 is in a well body structure formed by surrounding masonry bodies, a top cover plate and side beams, and a rectangular water inlet is formed in the top. The rainwater inlet is generally parallel to the road surface, and the rainwater grate 2 at the inlet is placed on the well seat and is made of metal such as iron.
In the embodiment, as shown in fig. 2, two horizontal slideways 3 made of concrete are symmetrically installed at a horizontal position 5 cm-8 cm below the rainwater wellhead. The motor 32 is arranged at the tail end of the horizontal slideway 3, the fixed seat 33 is arranged near the middle position of the horizontal slideway 3, the transmission shaft 31 is arranged between the motor 32 and the fixed seat 33, the inner side sliding rod 41 of the outer filtering structure 4 and the outer side sliding rod 41 of the inner filtering structure 44 are penetrated by the transmission shaft 31, and can synchronously move on the horizontal slideway 3 under the driving of the motor 32. The outer filtering structure 4 and the inner filtering structure 44 are composed of a sliding rod 41, a flexible wire 42 and an expansion joint 43.
The single horizontal slideway 3 is provided with a combination of two pairs of motors 32, a transmission shaft 31 and a fixed seat 33, and the outer filtering structure 4 moves in the well through a sliding rod 41; the flexible wire netting 42 in the structural frame is used for filtering rain and dirt and intercepting sundries; the expansion joint 43 at the bottom of the structure can adjust the volume of the structure when the structure is closed. An infrared sensing device 5 is arranged on the inner wall of the middle height of the unfolded outer filtering structure 4 or the inner filtering structure 44 below the horizontal slide 3, and whether the filtering structure needs to be cleaned or not and whether the filtering structure needs to be rotated or not are judged according to the accumulation amount of sundries in the flexible wire netting 42 in the folded state of the outer filtering structure 4 or the inner filtering structure 44.
In the initial working state of this embodiment, specifically, as shown in fig. 2, the outer filter structure 4 is unfolded, and the inclination angle θ =50 ° between the flexible wire 42 of the outer filter structure 4 and the horizontal sliding way 3; the inner filtering structure 44 is in a closed state and is positioned in the center of the horizontal slideway 3; the infrared sensing device 5 is in an open state, and normally receives an electric signal which is not blocked in the outer filtering structure 4; the motor 32 fixes the outer filter construction 4 and the inner filter construction 44 in the position shown by way of the drive shaft 31.
As shown in fig. 2-4, in operation, when rainwater enters the rainwater well 1 from the rainwater grate 2, impurities entrained in the rainwater are trapped by the flexible wire netting 42 on the deployed outer filtering structure 4. When foreign objects accumulate in the outer filter structure 4 in excess of 2/3 of the volume of the outer filter structure 4, the infrared signal of the infrared sensor device 5 is completely blocked. Upon receiving the relevant electric signal, the motor 32 starts to rotate the transmission shaft 31, pulling the inner slide bar 41 of the outer filter structure 4 and the outer slide bar 41 of the inner filter structure 44, so that the outer filter structure 4 is contracted and closed, and the inner filter structure 44 is expanded, thereby forming the working state shown in fig. 4. Meanwhile, the motor 32 transmits related electric signals to a municipal pipe network command position to prompt the specific position of the rainwater well needing to be cleaned, and timely arranges cleaning personnel to clean up the sundries of the external filtering structure 4.
When the motor 32 has operated the drive shaft 31, the outer filter structure 4 is closed and fixed close to the inner wall of the well. At this time, the inner filter structure 44 pulled by the transmission shaft 31 has no impurities inside, so that the infrared sensor 5 normally receives the infrared signal and continues to perform a new round of rain and sewage filtering and sewage intercepting. Before the cleaning personnel do not clear up external filtration 4, because interior filtration 44 also can filter, cut dirty work, very big reduction because the pipe network that the untimely leads to of decontaminating blocks up the risk.
