Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a vertical grate type rainwater outlet used in cities. Background Art

[0002] The rainwater inlet is a part of road drainage. The purpose of designing the rainwater inlet is to collect the rainwater that cannot penetrate the road surface into the road drainage system to prevent the road surface from being damaged by long-term soaking of rainwater. At present, urban road rainwater inlets mainly include vertical grate type, flat grate type and composite type. The vertical grate type is a rainwater inlet perpendicular to the road surface and set at the curb. The flat grate type is a rainwater inlet parallel to the road surface and set at the edges of both sides of the lane. The composite type is a composite rainwater inlet that is compatible with the vertical grate type and the flat grate type.

[0003] The drainage of existing vertical grate rainwater outlets is mainly connected to the drainage irrigation canal through pipes. In addition to the direct surface rainwater infiltration during rainfall, the water use of road green belts also requires artificial watering. However, due to the obstruction of green belt plants and surface runoff, the actual infiltration volume at the green belt location is less than the rainfall. In the absence of long-term rainfall, the green belt cannot be fully supplemented by natural rainwater, which leads to an increase in artificial watering and an increase in urban water consumption.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a vertical grate type rainwater outlet for use in cities, which has the following beneficial effects:

[0016] 1. The vertical grate rainwater outlet is equipped with two sets of drainage pipes, one set is connected to the existing drainage irrigation channel for external discharge, and the other set is directly connected to the soil layer in the green belt.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-5 A vertical grate rainwater inlet for use in a city, comprising a rainwater well 1, the rainwater well 1 is built in a green belt 20 and close to a motor vehicle lane 19, a plurality of rainwater wells 1 are built along the road at intervals of 30m, the outer wall of the rainwater well 1 facing the motor vehicle lane 19 is flush with the surface of the curb 21, the top of the rainwater well 1 is open, a well cover 2 is installed at the opening position, a water inlet 18 is reserved on the front side of the rainwater well 1 above the motor vehicle lane 19, and a vertical rainwater grate 7 is installed on the rainwater well 1 at the water inlet 18;

[0028] A main drainage outlet 5 is reserved at the lower middle position of the rear side of the rainwater well 1. A main drainage pipe 3 is buried in the green belt 20 on the rear side of the rainwater well 1 at a height corresponding to the main drainage outlet 5. A plurality of secondary drainage outlets 6 are reserved at the bottom position of the rear side of the rainwater well 1. The diameter of the secondary drainage outlets 6 is one third of the diameter of the main drainage outlet 5. A secondary drainage pipe 4 is buried in the green belt 20 on the rear side of the rainwater well 1 at a height corresponding to the secondary drainage outlet 6. The diameter of the secondary drainage pipe 4 is also one third of the diameter of the main drainage pipe 3.

[0029] The outlet of the main drainage pipe 3 is connected to the existing drainage irrigation channel, and the outlet of the auxiliary drainage pipe 4 is extended and arranged in the green belt 20. When it rains, rainwater is collected through the surface of the motor vehicle lane 19, and then enters the rainwater well 1 through the vertical rainwater grate 7 for accumulation. When the water level reaches the height of the main drainage outlet 5, the rainwater is directly discharged to the irrigation channel through the main drainage pipe 3 for unified drainage. When the rainwater enters the auxiliary drainage pipe 4, it flows directly to the green belt 20 for infiltration and drainage, forming a double-row effect with external drainage as the main and infiltration of the green belt 20 as the auxiliary. While the surface of the green belt 20 is raining and infiltrating, additional rainwater is added. In the case of short-term rainfall, the green belt 20 can obtain more rainwater replenishment.

[0030] In the present embodiment, a gate plate 11 is provided at a position corresponding to the auxiliary drainage outlet 6 in the rainwater well 1, and the gate plate 11 is close to the inner wall of the rainwater well 1 at the position of the auxiliary drainage outlet 6. Limiting angle brackets 12 with an L-shaped cross-section are installed on the inner walls of the rainwater well 1 on the left and right sides of the gate plate 11. The two side edges of the gate plate 11 abut against the limiting angle brackets 12 at the corresponding positions to form an upward and downward movable front and rear limit. A bent pipe 14 is provided in the rainwater well 1 above the gate plate 11, and a pipe seat 15 is welded and installed on the bent pipe 14. The pipe seat 15 is fixed by being pre-buried in the rainwater well 1, and a connecting rope 13 is passed through the bent pipe 14. One end of the connecting rope 13 is fixed to the top surface of the gate plate 11, and the other end is fixed to the counterweight block 16. A floating block 17 is installed on the bottom surface of the counterweight block 16. The weight of the counterweight block 16 is 1.5 times the weight of the gate plate 11, and the buoyancy of the floating block 17 is 3 times the weight of the counterweight block 16.

[0031] When there is no rain or there is no water in the rainwater well 1, the floating block 17 lacks water as buoyancy support. The deadweight of the counterweight 16 will pull the gate plate 11 up through the connecting rope 13, so that the secondary drain outlet 6 is opened. When rainwater enters the rainwater well 1 and the water level continues to rise to the height of the floating block 17, the floating block 17 uses water as buoyancy support to drive the counterweight 16 to lift up, and the gate plate 11 then drops and blocks the secondary drain outlet 6. This indicates that the rainfall is large, and the rainwater in the rainwater well 1 is drained through the main drain pipe 3. When the rainfall stops and the water level continues to drop, the counterweight 16 drops again and pulls the gate plate 11 up, thereby opening the secondary drain outlet 6, so that the remaining rainwater in the rainwater well 1 is drained through the main drain pipe 3 and the secondary drain pipe 4 at the same time. When the water level is lower than the main drain outlet 5, it can only be drained to the green belt 20 through the secondary drain pipe 4. When the rainfall is limited, rainwater can be supplied to the green belt 20 as much as possible for green plants to absorb.

[0032] In this embodiment, a plurality of openings 8 and openings 9 are provided on the vertical rain grate 7, both of which are square openings, and the length and width of opening 1 8 are greater than the length and width of opening 2 9. The four sides of the front side of the vertical rain grate 7 corresponding to the openings 8 are chamfered inwards, and a plurality of protrusions 10 are integrally formed and installed between adjacent openings 8 on the front side of the vertical rain grate 7.

[0033] Compared with the existing long strip drainage, the square drainage opening has a better blocking effect on long and flat debris such as leaves and branches, and can prevent branches and leaves whose sizes are larger than the length and width of the opening from entering the rainwater well 1. The four sides of the opening 8 are chamfered to increase the entrance surface, and the setting of the protrusion 10 makes the front side of the vertical rainwater grate 7 uneven and concave-convex. For larger leaves or other debris such as paper with a large surface area and a certain degree of flatness, the concave-convex structure can prevent them from clinging to the surface of the vertical rainwater grate 7 under the action of water flow pressure and water viscosity, and blocking the opening for a long time. The concave-convex structure can create a gap between it and the vertical rainwater grate 7, so that when rainwater rushes into the gap, the debris can be pushed away.
