The first embodiment:
referring to fig. 1 and fig. 2 to 6, the present application provides a novel rainwater energy dissipation device, which includes a ground manhole cover 1, a concrete casing 2, at least one water inlet pipe 3, at least one water outlet pipe 4, at least one flow distribution plate 5, and at least two drainage plates 6; wherein, the concrete shell needs to meet the requirements of structural strength, sealing performance and erosion resistance; the ground manhole covers 1 can be two and are arranged on the top surface of the concrete shell 2 at intervals, under the normal condition, the ground manhole covers 1 are arranged on the top of the concrete shell 2, and in order to prevent external rainwater from entering the energy dissipation well, the elevation of the energy dissipation manhole cover is usually set to be slightly higher than the elevation of the ground; meanwhile, the water inlet pipeline 3 is arranged on one side of the upstream of the concrete shell 2 and is used for discharging rainwater of a siphon system or a non-siphon system which needs energy dissipation into the concrete shell 2; the water outlet pipeline 4 is arranged on one side of the downstream of the concrete shell 2 and used for discharging rainwater in the concrete shell 2, the water outlet pipeline 4 is generally set to be a single pipe with a larger diameter for discharging, and the bottom of the water outlet pipeline 4 is suggested to be flush with the bottom of the concrete shell 2, so that residual accumulated water is reduced, and peculiar smell is reduced; the flow distribution plate 5 is integrally arranged on the bottom surface of the inner cavity of the concrete shell 2 along the height direction of the concrete shell 2 and is positioned at a position close to the water inlet pipeline 3, the flow distribution plate 5 and two opposite inner walls of the concrete shell 2 are arranged at intervals, the flow distribution plate 5 is arranged behind the drainage plate 6 and has various arrangement forms, and the part directly impacted by the water body of the water inlet pipe needs to be subjected to anti-scouring treatment; the two drainage plates 6 are respectively arranged on the bottom surface of the inner cavity of the concrete shell 2 at intervals along the height direction of the concrete shell 2, are respectively integrally formed with two opposite inner walls of the concrete shell 2, and are positioned at the positions close to the water outlet pipeline 4; the inner cavity of the concrete shell 2 is sequentially divided into a flow distribution area 7, an energy dissipation area 8 and an outflow area 9 from a position close to the water inlet pipeline 3 to a position close to the water outlet pipeline 4 by the flow distribution plate 5 and the drainage plate 6, the flow distribution area 7 is positioned between the water inlet pipeline 3 and the flow distribution plate 5, the energy dissipation area 8 is positioned between the flow distribution plate 5 and the drainage plate 6, and the outflow area 9 is positioned between the drainage plate 6 and the water outlet pipeline 4. The shunt plate 5 and the drainage plate 6 are simultaneously poured when the concrete shell 2 is poured in construction, so that the integral stress structure is more reliable; and, the surface of the flow distribution plate 5 directly impacted is processed into a rough surface to increase the surface roughness and increase the turbulent dissipation. The high-speed water body which is mixed with bubbles and gas clusters and flows in from the water inlet pipeline 3 is divided into two parts with small flow difference through the splitter plate 5. If there are a plurality of inlet channels 3 then symmetrical arrangement, will design the flow big as far as possible to the centre arrangement, to the gravity outflow water pipeline 4 with it toward outside setting. The area between the flow distribution plate 5 and the drainage plate 6 is an energy dissipation area 8, and the two water bodies are collected in the energy dissipation area 8 through the drainage of the side wall of the concrete shell 2 and the drainage plate 6, so that the kinetic energy is counteracted with each other, and the water body with low flow velocity flows out of the water outlet pipeline 4. The inlet pipe 3 is the end of the siphon rainwater pipe, and can be arranged in a single pipe or in a plurality of pipes. The rainwater flow rate of the non-siphon rainwater pipe is small, the non-siphon rainwater pipe can be arranged close to the edge, the elevation of the water inlet pipeline 3 is higher than that of the water outlet pipeline 4, and rainwater backflow is prevented.
The working principle and the energy dissipation method are as follows: the flow distribution plate 5 divides the high-speed fluid flowing in from the water inlet pipeline 3 into two flows with small flow difference, the two flows are adjusted by the drainage plate 6 to flow backwards, the two flows of water with high speed mutually rush to dissipate energy, and then the water with low flow speed flows out through the water outlet pipeline 4. Therefore, the designed construction measures of the flow distribution plate 5 and the drainage plate 6 can enable two water bodies of flow distribution to attack each other, and the turbulence dissipation characteristic of the fluid is utilized to dissipate energy, so that long-term scouring of the concrete wall surface is reduced. Meanwhile, the flow distribution plate 5 and the drainage plate 6 are directly connected with the concrete shell 2, so that a template can be conveniently erected on site and the construction can be rapidly carried out. The device can dissipate kinetic energy carried by outlet water flow of the siphon pressure flow rainwater outlet pipeline 4 in a small space and a short distance, so that the flow velocity of downstream water flow is reduced, destructive effects such as cavitation erosion, pulsation, vibration, abrasion and scouring caused by the water flow are weakened, and the safe and stable work of a drainage inspection well and a drainage pipeline is ensured. The siphon energy dissipation device has the characteristics of simple construction, reliable structure, good energy dissipation effect and the like, and is used for solving the problems of lifting of a well cover, too high flow velocity of a discharged water body and the like in a common siphon rainwater energy dissipation well.
It should be noted that, in this embodiment, for the water inlet pipe 3 with a small design flow, the flow distribution plate 5 may be designed as one, and may be a plate-shaped structure with a rectangular cross section, which may be arranged along the width direction of the concrete casing 2; meanwhile, the distances between the two ends of the flow distribution plate 5 and the two opposite inner walls of the concrete shell 2 are equal. In other embodiments, the diversion plates 5 may be arranged along the direction intersecting the width direction of the concrete shell 2, and the number and size thereof may be designed according to the actual use situation.
It should be noted that, in this embodiment, the two drainage plates 6 are located on the same straight line, and both are disposed along the width direction of the concrete casing 2 and extend upward along the height direction of the concrete casing 2; meanwhile, the cross section of the drainage plate 6 is of a rectangular plate-shaped structure and is vertically connected with the inner wall of the concrete shell 2. In other embodiments, the drainage plate 6 may also be a plate-shaped structure with a rectangular cross section, and extend in a direction away from the flow distribution plate 5 and form an acute angle with the inner wall of the concrete casing 2.
In this embodiment, the concrete casing 2 may be made of reinforced concrete or masonry.
The inner cavity of the concrete shell 2 is divided into three areas by the flow distribution plate 5 and the drainage plate 6: (1) a flow distribution area 7 between the water inlet pipeline 3 and the flow distribution plate 5, (2) an energy dissipation area 8 between the flow distribution plate 5 and the drainage plate 6, and (3) an outflow area 9 between the drainage plate 6 and the water outlet pipeline 4.
Figure 1 shows a schematic diagram of the opposed-current energy dissipation, showing the flow path from the entry to the exit of the energy dissipating well. As shown in figure 1, siphon rainwater enters a well chamber of the energy dissipation inspection well through a water inlet pipe, is divided into two parts of water with equivalent flow after being divided by a flow dividing plate 5, and the water is impacted on the wall surface of the well chamber and then is gathered to an energy dissipation area 8 through a drainage plate 6. Two high-speed fluids with equal flow speed, equal flow and opposite directions are converged to form a turbulent flow phenomenon with extremely high Reynolds number in the energy dissipation zone 8. After the energy dissipation area 8 finishes energy dissipation, the water body is adjusted to flow backwards through the outflow area 9 to form a low-flow-rate and non-full-pipe water body discharge siphon rainwater energy dissipation device. Wherein the water inlet pipe 3 and the water outlet pipe 4 are designed according to the requirement. The ground well cover 1 of the siphon energy dissipation inspection well can adopt a common nodular cast iron well cover or other anti-corrosion materials, and needs to have certain weight.
In conclusion, the novel rainwater energy dissipation device can simply, safely and effectively eliminate kinetic energy carried by water flow at the tail end of a siphon pressure flow rainwater drainage pipeline, and safely dissipate energy carried by water flow at the outlet of the siphon pressure flow rainwater drainage pipeline in a smaller space and a shorter distance, so that upstream and downstream water flows are properly connected to avoid overflow; meanwhile, the water flow control device can weaken the destructive effects of cavitation erosion, pulsation, vibration, abrasion, scouring and the like caused by water flow, and ensures the safe and stable work of the drainage inspection well and the drainage pipeline.
