Detailed Description
The invention is described in detail below with reference to the figures and examples.
In an embodiment, a municipal pipeline based on rainwater pressure sensing is shown in fig. 1 and comprises a rainwater pipeline 1, a sewage pipeline 2, a diversion pipeline 3 and a communication pipeline 4. Sewage pipe 2 parallel arrangement is in rainwater pipeline 1 below, and diversion pipeline 3 is fixed to be set up in the upper end of sewage pipe 2 inner wall. The communicating pipe 4 is arranged between the rainwater pipeline 1 and the sewage pipeline 2, the upper end of the communicating pipe 4 is communicated with the rainwater pipeline 1, and the lower end of the communicating pipe 4 is communicated with one end of the diversion pipeline 3. The other end of the diversion pipeline 3 is communicated with the sewage pipeline 2. Therefore, one end of the diversion pipeline 3 connected with the communicating pipe forms an inflow end for rainwater to flow in, and the other end of the diversion pipeline 3 forms an outflow end for rainwater to flow out.
Specifically, the communicating pipe 4 includes an upper vertical section 5, a horizontal section 6 and a lower vertical section 7, the upper vertical section 5 and the lower vertical section 7 are vertically arranged, the horizontal section 6 is horizontally arranged, the inner diameter of the pipe of the horizontal section 6 is larger than the inner diameter of the pipe of the upper vertical section 5 and the lower vertical section 7, and the inner diameter of the pipe of the upper vertical section 5 and the lower vertical section 7 is equal. The upper end of the upper vertical section 5 is communicated with a rainwater pipeline 1, and the lower end is connected with one end of the horizontal section 6; the other end of the horizontal section 6 is connected with the upper end of the lower vertical pipeline, and the lower end of the lower vertical pipeline is connected with the inflow end of the diversion pipeline 3. A division plate 8 is fixed in the vertical middle of the diversion pipeline 3 along the horizontal axial direction, and the division plate 8 divides the diversion pipeline 3 into a fast flow channel 9 arranged on the upper side and a slow flow channel 10 arranged on the lower side.
Be provided with the one-level water pressure sensor 11 that is used for detecting the interior water level of rainwater pipeline 1 in rainwater pipeline 1, the upper end of going up vertical section 5 is provided with the one-level stop valve 12 that opens when the water level reaches the 11 threshold values of one-level water pressure sensor in rainwater pipeline 1, be provided with the second grade water pressure sensor 13 that is used for detecting the water level in horizontal segment 6, the inflow end of torrent passageway 9 is provided with the second grade stop valve 14 that opens when the water level reaches second grade water pressure sensor 13 threshold values in horizontal segment 6. And a plurality of one-way slow flow pieces 15 are axially arranged in the slow flow passage 10.
When the rainfall amount of the rainwater is increased, the water level in the rainwater pipeline 1 rises, and after the rainwater reaches the threshold value of the primary water pressure sensor 11, the primary water pressure sensor 11 is triggered to open the primary stop valve 12, and part of the rainwater in the rainwater pipeline 1 enters the slow flow channel 10 of the flow guide pipeline 3 through the communication pipeline 4 and flows into the sewage pipeline 2 from the slow flow channel 10. And because the one-way slow flow sheet 15 is arranged in the slow flow channel 10, the one-way slow flow sheet 15 can deform only when rainwater flows in the slow flow channel 10, and the rainwater flows through gaps generated in the slow flow channel 10. When the rainwater pipeline 1 is filled with more accumulated water and cannot be completely discharged through the slow flow channel 10, the inflow speed of the rainwater at the horizontal section 6 is higher than the outflow speed, so that the water level in the horizontal section 6 rises. After the level section 6 reaches the threshold value of the secondary water pressure sensor 13, the secondary water pressure sensor 13 is triggered, so that the secondary stop valve 14 is opened. Rainwater can flow out from the rapid flow channel 9 at the same time, so that the rainwater is accelerated to be discharged into the sewage pipeline 2, and the diversion pipeline 3 is filled with rainwater in the discharging process, so that the condition that gas in the sewage pipeline 2 cannot enter is ensured.

The magnetically sensitive float 17 is formed of a member capable of changing a magnetic field, such as a magnet, fixed inside the float. The hall switch 18 can be fixed above a position near the float after it floats. When the magnetic floating ball 17 approaches the Hall switch 18, the intensity of the magnetic field received by the Hall switch 18 changes. When the magnetic field intensity changes to the set threshold value, the Hall switch 18 outputs an electric signal for controlling the opening, and the first-stage stop valve 12 is opened. The threshold value of the primary water pressure sensor 11 is set at 1/2 to 2/3 of the water level of the rainwater pipe 1. Preferably 2/3.
Further, as shown in fig. 1, the primary cut-off valve 12 is an electric cut-off valve, and is controlled to open and close by an electric signal output by the primary water pressure sensor 11. The rainwater pipeline 1 is provided with a protective mesh enclosure 19 covering the outer side of the primary stop valve 12 at the inflow end of the water pressure sensor. The protective mesh 19 has a protective function, and prevents sundries from entering the communicating pipeline 4 through the first-stage stop valve 12.
As shown in fig. 1, check valves 20 for preventing the diversion pipeline 3 from flowing to the rainwater pipeline 1 are arranged in the upper vertical section 5 and the lower vertical section 7. The check valve 20 is one-way open and can function to prevent air from flowing from the sewage conduit 2 to the storm water conduit 1.
As shown in fig. 1, the structure of the secondary water pressure sensor 13 is similar to that of the primary water pressure sensor 11, and also includes a swing rod 16 hinged to the inner wall of the upper side of the upper horizontal section 6, a magnetic floating ball 17 fixedly connected to the lower end of the swing rod 16, and a hall switch 18 arranged on the outer wall of the horizontal section 6. The threshold value of the secondary water pressure sensor 13 may be 2/3-3/4, in the embodiment 3/4, when the water level reaches the height of the horizontal section 6. After the water level in the communication water pipe rises to 3/4, the secondary water pressure sensor 13 quickly responds to open the secondary cut-off valve 14.
As shown in fig. 1 and 3, the lower end surface of the partition plate 8 is in a downwardly convex arc shape. In the slow flow passage 10, the one-way slow flow pieces 15 are evenly distributed in the axial direction, and a fixing groove 21 for fixing the one-way slow flow piece 15 is opened on the lower side of the partition plate 8. The cross-sectional shape of the one-way baffle 15 is the same as that of the buffer channel 10, and is made of rubber. The upper side of the one-way slow flow sheet 15 is integrally connected with a clamping convex rib 22 with the thickness thicker than that of the one-way slow flow sheet 15. The clamping convex rib 22 is clamped in the fixing groove 21, so that the fixed connection between the one-way slow flow sheet 15 and the slow flow channel 10 is realized. The lower side of the one-way slow flow sheet 15 abuts against the lower side wall of the slow flow channel 10, and a thickened edge 23 extends from the lower end of the one-way slow flow sheet 15 to the outflow end. The thickened edge 23 makes the one-way slow-flow sheet 15 not easy to turn over toward the side of the inflow end. And further, the lower side of the slow flow channel 10 is convexly provided with a convex edge 25 at the side close to the inflow end of the one-way slow flow sheet 15, the convex edge 25 is attached to the one-way slow flow sheet 15 when the one-way slow flow sheet 15 is in a closed state, and the one-way slow flow sheet 15 is further limited to turn over towards the inflow end. In order to reduce the obstruction of the water flow by the convex edge 25, the side wall of the convex edge 25 towards the inflow end is provided with an inclined surface.
As shown in fig. 4, the section of the rapid flow channel 9 is circular, the second stage stop valve 14 is also an electrically controlled stop valve, and is fixed at the inflow end of the rapid flow channel 9, the outflow end of the rapid flow channel 9 is provided with a blocking net 26, the edge of the upper side of the blocking net 26 is welded with a net cage 27, and the net cage 27 is filled with absorbent cotton 28. The blocking net 26 is used for blocking sundries in the sewage pipeline 2 from entering the torrent channel 9, and the absorption cotton 28 can play a role of blocking air in a period of time after water absorption, so that waste gas is further prevented from entering the torrent channel 9.
The working process and the beneficial effects of the invention are as follows: when the water level in the rainwater pipeline 1 rises to 2/3 of the whole water level, the Hall switch 18 in the primary water pressure sensor 11 is triggered to open the primary stop valve 12, so that the rainwater pipeline 1 firstly enters the communicating pipeline 4 and then enters the slow flow channel 10 of the flow guide pipeline 3. The one-way slow flow pieces 15 in the slow flow channel 10 are opened under the impact of rainwater, so that the rainwater flows through a gap generated between the slow flow channel 10 and the one-way slow flow pieces 15. When the water cannot be completely discharged through the slow flow passage 10, the water level in the horizontal section 6 rises. After the water level section 6 reaches 2/3 of the water level, the secondary water pressure sensor 13 is triggered, so that the secondary stop valve 14 is opened. Rainwater can flow out of the rapid flow channel 9 at the same time, so that the speed of draining rainwater into the sewage pipeline 2 is increased. In the two discharging processes, the gap in the slow flow channel 10 is generated by the pushing of water flow, so that the gap can be kept closed when no water flow exists, and the polluted gas in the sewage pipeline 2 can not enter the communicating channel through the slow flow channel 10; and the torrent channel 9 is opened only after water is accumulated in the horizontal section 6, and the torrent channel 9 is filled with the accumulated water, so that a gap for the polluted gas to enter does not exist in the torrent channel 9. Therefore, the sewage pipeline has the advantage of preventing the polluted gas in the sewage pipeline 2 from entering the rainwater pipeline 1.
