The top rod plate 16 is arranged below the water filtering plate 15, the top rod plate 16 is of a grid structure so as to facilitate water drainage, vertical top rods 17 with different lengths are fixedly arranged on the top rod plate 16, and the top rods 17 penetrate through filtering holes of the water filtering plate 15. When sheet objects such as leaves and paper sheets enter the water filtering plate 15, the filtering holes are easily blocked, so that the water drainage effect is influenced, the sheet objects can be jacked to a certain height under the action of the jacking rods 17, and the jacking rods 17 with different lengths can jack the sheet objects to different heights, so that enough gaps can be reserved between the sheet objects and the jacking rods 17, and water flow can pass through the gaps quickly. A series of water filtering holes 10 are arranged on the upper shell 7 above the water filtering plate 15 to accelerate the water filtering speed.

The lower shell 8 is of a shell structure with an opening at the upper part, the lower shell 8 is arranged below the upper shell 7, and a split structure or an integrated structure, namely a part, can be arranged between the lower shell 8 and the upper shell 7. The lower part of the upper case 7 is inserted into the lower case 8, and a gap between the lower end of the upper case 7 and the upper end of the lower case 8 forms an overflow. Lower casing 8 one side be the drainage side, the opposite side be the retaining side, escape canal 2 be located the below of lower casing 8 drainage side, retaining ditch 3 be located the below of lower casing 8 retaining side. The rainwater enters the urban drainage system from the drainage side of the lower shell 8, and the rainwater enters the urban water storage system 4 through the water storage side. In the drawings, the left end is a drain side and the right end is a water storage side. The upper edge of the lower shell 8 is inclined, the drainage side is high, and the water storage side is low. The upper side wall of the lower shell 8 is provided with a drain hole 9 and a water storage hole 18 respectively, the drain hole 9 is positioned on the side wall of the drainage side, the lower edge of the drain hole 9 is higher than the lower wall of the lower shell 8, and the position in the lower shell 8 below the drain hole 9 is used for storing silt. The water storage hole 18 is positioned on the side wall of the water storage side, wherein the height of the water storage hole 18 is higher than that of the drain hole 9, a cover body 19 structure is arranged at the position of the water storage hole 18, and the water storage hole 18 is completely covered by the cover body 19. The cover 19 is located inside the lower casing 8, the upper edge and the two side edges of the cover 19 are respectively fixed and tightly attached to the side wall of the lower casing 8, and an opening is formed between the lower edge of the cover 19 and the side wall of the casing.

The operating principle of the grate component 1 is as follows: when raining, the rainwater on the road surface enters the upper shell 7 through the rainwater grate 5, and the rainwater is filtered through the water filtering plates 15 and the water filtering holes 10 in the upper shell 7, so that the rainwater pipe net is prevented from being blocked due to accumulation of sundries, and then the rainwater enters the lower shell 8. Since the drain hole 9 is located at a low position, rainwater is first drained from the drain hole 9, and after a lapse of time, the amount of water increases and the water level rises, so that the rainwater is drained through the drain hole 9 and the water storage hole 18 at the same time. At the beginning, rainwater is dirty after the rainwater scours the road surface, so that dirty water is firstly drained from the drain holes 9, the road surface is scoured clean after a period of time, the rainwater is relatively clean, and clean rainwater is drained into the water storage system 4 from the water storage holes 18 to store water.

After the water is filtered, partial impurities still exist in the rainwater, and the impurities comprise sediment such as silt, fine floating objects and oil stains. Sediment such as silt is precipitated in the lower shell 8 and stays at the bottom of the lower shell 8; the floaters and the oil stains float on the water surface, when the water amount in the lower shell 8 is small, the floaters and the oil stains can be discharged into a city drainage system from the drainage hole 9, and the impurities can be removed by the city sewage treatment system or a natural decomposition mode; when the water level rises, as shown in fig. 5, rainwater enters the water storage hole 18 from the lower part of the cover body 19 through the action of the cover body 19, and floaters on the water surface are isolated outside the cover body 19, so that oil stains and floaters are prevented from entering the water storage system 4.

When heavy rain falls, the drainage holes and the water storage holes 18 cannot meet the drainage requirement of the lower shell 8, the water level in the lower shell 8 rises rapidly, and rainwater overflows from the upper edge of the lower shell 8, as shown in fig. 6, the drainage side of the upper edge of the lower shell 8 is higher than the water storage side, so that rainwater is preferentially drained from the water storage side and enters the water storage system 4 when heavy rain falls, and the requirement of water storage can be met even in short-time heavy rain.

Since the lower part of the upper housing 7 is inserted into the lower housing 8, when rainwater overflows in the lower housing 8, as shown in fig. 6, the rainwater enters the lower housing 8 from the lower part of the upper housing 7 through the action of the upper housing 7, and the water surface floaters are isolated inside the upper housing 7, thereby preventing oil stains and floaters from entering the water storage system 4.

As shown in fig. 6, when raining, the lower case 8 is filled with rainwater, and the weight of the lower case increases, so that the tail end of the lever 12 is pressed down, and the head end of the lever 12 is lifted up to jack up the rainwater grate 5. The rainwater grate 5 can accelerate the water inlet speed of the rainwater port after being jacked up, so that drainage can be accelerated in heavy rain weather, and urban waterlogging caused by surface water is avoided. When the rainwater grate 5 is jacked up and pedestrians or vehicles walk from the rainwater grate 5, the rainwater grate 5 can be pressed down, and when the vehicles or the pedestrians leave, the rainwater grate 5 is naturally lifted. Therefore, the rainwater grate 5 can accelerate the pavement drainage after being lifted, and the influence on pedestrians and vehicles walking on the pavement can be avoided.

When silt is more in lower casing 8, because silt weight is great, through can with rainwater grate 5 jack-up, consequently when the rainwater grate 5 jack-up back in the heavy rain weather of non-, can remind the staff to lower the casing 8 in silt more, need clear up. When impurities in the grate component 1 need to be cleaned, the grate component 1 can be taken out, and hoisting equipment can be installed on a working vehicle during actual use, so that the grate component 1 can be conveniently taken out and cleaned. Clear up the rainwater pipe network and need the staff to get into the well usually and clear up at present, through the mode of taking out the clearance with grate subassembly 1, do not need to go into the well, consequently it is more high-efficient convenient.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
