Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the invention, fall within the scope of protection of the invention.

As shown in fig. 1-3, according to an embodiment of the present invention, a siphon-type rainwater grate drainage system includes a rainwater grate disposed at an upper portion of a shaft 7, the rainwater grate includes a fixed frame 1, a plurality of head ends of vortex-preventing deflectors 2 are fixedly connected to the fixed frame 1, tail ends of the vortex-preventing deflectors 2 extend backward, top surfaces of the vortex-preventing deflectors 2 gradually rise upward from the tail ends to the head ends, a plurality of top surfaces of the vortex-preventing deflectors 2 are fixedly connected with one ends of an air baffle 3 disposed horizontally between the tail ends and the head ends, the other ends of the air baffle 3 extend backward and correspond to the size of the shaft 7, a buried cross pipe 6 is connected to the bottom of the shaft 7, a buried vertical pipe 9 is connected to the buried vertical pipe 6, the buried vertical pipe 9 is connected to a rainwater drainage well 10, and the buried cross pipe 6 and the buried vertical pipe 9 form a negative pressure region together through a height difference with the rainwater grate.

In a specific embodiment of the present invention, a well wall 8 is disposed at the outer side of the well bore 7, an opening matched with the fixed frame 1 is formed on the well wall 8, and a well ring 4 and a well lid 5 are disposed at the top of the well wall 8.

In one embodiment of the present invention, the part of the buried stand pipe 9 communicating with the rainwater drainage well 10 is a positive pressure area.

In one embodiment of the present invention, the fixing frame 1 is located on the curb stone 12 on top of the road surface 11.

In one embodiment of the invention, the rain drain well 10 is in communication with the atmosphere.

In order to facilitate understanding of the above technical solutions of the present invention, the following describes the above technical solutions of the present invention in detail by a specific usage manner.

The fixed connection mode can be replaced by conventional technical means such as bolt connection, clamping connection and the like.

The system utilizes the energy generated by the height difference between the road surface and the municipal rainwater pipeline, and adjusts the configuration of the pipeline through accurate calculation, so as to balance the head loss, the water pressure and the flow velocity of the system pipe network. Under the design state, the pipeline reaches a full pipe flow state, so that a road system for rapidly sucking and discharging the rainwater on the road surface is realized.

The main working process of the system is roughly divided into the following steps: in the early stage of rainfall, when the rainwater height at the road surface 11 does not exceed the water collection depth of the air partition plate 3, the working condition of the whole drainage system is the same as that of the gravity drainage system. Along with the duration of rainfall, when the rainwater height of road surface 11 department reaches air separator 3 catchment degree of depth, owing to adopted vortex-proof flow guide plate 2, through vortex-proof flow guide plate 2 steerable rainwater flow and adjustment flow state avoid the vortex, can prevent the air entrained when rainwater gets into the system through air separator 3 simultaneously, make each pipeline in the system be full flow state, when the water flow increase water level increases and when the height of air separator 3 is walked, the below of air separator 3 is full flow state, the flowing water can not form the vortex simultaneously, can prevent to take the air through steady rivers, thereby the separation air gets into in this system.

By utilizing the potential energy of the height of the road surface 11 and the height of the rainwater grate, when rainwater continuously flows through the buried transverse pipe 6 and is transferred into the buried vertical pipe 9 to fall, a siphon action is formed, a negative pressure area is formed, the maximum negative pressure is formed in the pipe where the buried transverse pipe 6 is transferred into the buried vertical pipe 9, and the rainwater at the road surface 11 is discharged to the rainwater drainage well 10 communicated with the atmosphere at a higher flow rate under the suction action of the negative pressure in the pipeline.

The fixing frame 1 and the vortex-preventing guide plate 2 can prevent road surface garbage, fallen leaves and the like from entering the drainage system in the drainage process, so that the drainage system is prevented from being blocked by garbage. After a certain time, the well cover 5 can be opened to clean the garbage in the rainwater grate, so that the smoothness of the drainage system is kept.

In summary, by means of the technical scheme of the invention, the siphon effect can be utilized to realize the functions of rapidly sucking and discharging the rainwater on the road surface.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
