technical field

The invention relates to a municipal drainage system, in particular to an intelligent flat-grate rainwater well based on a V-shaped filtering structure, belonging to the technical field of municipal drainage.

Background technique

Reducing the risk of blockage of urban rainwater wells is an important part of building a sponge city. The rainwater well is the first entrance of the surface runoff into the municipal rainwater pipe network, and the rainwater well is connected with the rainwater pipe network. When it rains, the rain will bring the leaves, garbage, sand and other sundries on the road into the rainwater well through the rainwater inlet. Over time, rainwater wells and rainwater pipe networks are easily blocked by debris. Once the rainwater wells are not cleaned in time and the rainwater wells are blocked by debris, it will easily lead to urban waterlogging when it rains, resulting in extremely bad environmental impacts. In the existing rainwater pipe network, sanitation workers need to clean the rainwater wells in a timely manner, the cleaning frequency is high, and the rainwater wells that need to be cleaned immediately cannot be determined.

In the existing flat-grate rainwater well design, the common ones are: (1) A large filter bag is placed under the water inlet of the rainwater well to intercept and pack the sundries. However, due to the accumulation of debris in a space, the overflow of the inlet of the rainwater well is reduced, and there is still a high risk of clogging, and the sanitation personnel cannot accurately determine the rainwater well that needs to be cleaned. (2) Expand the underground volume of rainwater wells and set up multi-layer filter wellhead structures such as permeation filter wells. This method is expensive, difficult to maintain, and not easy to be widely promoted.

3. The present invention reduces the negative impact of the accumulation of debris in the filter structure on the overflow of rainwater by timely replacing the surface of the filter screen and placing the filter screen obliquely. When the debris in the outer V-shaped structure accumulates to a certain value, the outer V-shaped structure shrinks and closes, and the inner V-shaped structure starts to work. The V-shaped filter structure unfolded on the inside can pass rainwater at full flow, and the obliquely placed barbed wire in the V-shaped filter structure has a certain cascade filtering and interception effect on rainwater, which reduces the influence of debris accumulation on the rainwater overflow and reduces the The risk of urban waterlogging due to the small overflow of rainwater.

Detailed ways

In order to have a clearer understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

The present invention is mainly arranged in the road rainwater pipe network. Specifically, as shown in Figure 1, the boundary structure of the rainwater well 11 has a rainwater drainage pipeline 12, which is connected with the municipal rainwater pipe network. The rainwater well 11 is surrounded by masonry, top cover and side beams. Well body structure, the top is provided with a rectangular water inlet. The rainwater inlet is usually parallel to the road surface, and the rainwater grating 2 at the inlet is placed on the well seat and is made of metal such as iron.

In this embodiment, as specifically shown in FIG. 2 , two horizontal slideways 3 made of concrete are symmetrically installed at a horizontal position of 5 cm to 8 cm below the rainwater wellhead. The motor 32 is placed at the end of the horizontal slideway 3, the fixed seat 33 is placed at the middle of the horizontal slideway 3, the transmission shaft 31 is between the motor 32 and the fixed seat 33, the inner slide bar 41 of the outer filter structure 4 and the inner filter structure 44 The outer sliding rod 41 is penetrated by the transmission shaft 31 and can move on the horizontal slideway 3 synchronously under the driving of the motor 32 . The outer filter structure 4 and the inner filter structure 44 are composed of a sliding rod 41 , a flexible wire mesh 42 and an expansion joint 43 .

A single horizontal slideway 3 has a combination of two pairs of motors 32, a transmission shaft 31 and a fixed seat 33. The outer filter structure 4 realizes the movement in the well through the sliding rod 41; the flexible wire mesh 42 in the structure frame is used to filter rain, dirt, Retain debris; 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 below the horizontal slideway 3 and at the inner wall of the middle elevation of the unfolded outer filter structure 4 or inner filter structure 44. Accumulation amount, determine whether it needs to be cleaned and whether it is necessary to rotate the filter structure.

In the initial working state of this embodiment, the outer filter structure 4 is unfolded as shown in FIG. 2, and the inclination angle θ=50° between the flexible wire mesh 42 of the outer filter structure 4 and the horizontal slideway 3; the inner filter structure 44 is in a closed state, located at The center position of the horizontal slideway 3; the infrared sensing device 5 is in an open state, and the electrical signal is normally received without being blocked in the outer filter structure 4; the motor 32 fixes the outer filter structure 4 and the inner filter structure 44 through the transmission shaft 31. Icon location.

As shown in Figures 2-4, when the rainwater enters the rainwater well 1 from the rainwater grating 2, the sundries entrained in the rainwater are intercepted by the flexible wire mesh 42 on the unfolded outer filter structure 4. When debris accumulates in the outer filter structure 4 and exceeds 2/3 of the volume of the outer filter structure 4 , the infrared signal of the infrared sensor device 5 is completely blocked. The motor 32 receives the relevant electrical signal, the transmission shaft 31 starts to rotate, and pulls 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 unfolded. The working state shown in Figure 4. At the same time, the motor 32 transmits relevant electrical signals to the municipal pipe network command office, indicating the specific location of the rainwater well that needs to be cleaned, and arranges cleaning personnel to clean up the sundries in the external filter structure 4 in time.

After the motor 32 drives the transmission shaft 31 to work, the outer filter structure 4 is closed and fixed near the inner wall of the well. At this time, there is no debris inside the inner filter structure 44 pulled by the transmission shaft 31, so that the infrared sensor device 5 can normally receive infrared signals, and continue to perform a new round of rain and pollution filtering and pollution interception. Before the cleaning personnel clean the outer filter structure 4, the inner filter structure 44 can also perform filtering and pollution interception work, which greatly reduces the risk of pipe network blockage caused by untimely cleaning.

The specific embodiments described above further describe the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above descriptions are only specific embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
