Problems solved by technology
[0002] The simplest and most environmentally friendly technology to eliminate urban mosquitoes is to use a water grate that allows rainwater to pass through smoothly but mosquitoes cannot pass through. The applicant applied for it on November 19, 2003, and the patent number is: ZL200310110986X The name is urban sewer mosquito-killing water grate, and the application on December 30, 2005, the application number is 2005100224588, and the two technical solutions named urban sewer mosquito-killing water grate are all on the round hole type water grate skeleton plate Put on the isolation cover made of elastic thin strips, the disadvantage of this kind of water grate is that the water grate has a large footprint, and at the same time, in order to withstand the weight of the vehicle, it must have a thickness of more than 2cm, which causes the water grate. There are many sub-consumables and the cost is high. Second, the number of isolation covers is large and the manufacturing process is more complicated, which will also increase the cost

Embodiment Construction
[0015] Open length 30cm, wide 20cm rectangular hole on the side wall of urban road both sides and sidewalk or the intersection of green belt, hole communicates with sewer, adorn in the rectangular hole a water grate frame (1 ), the plane where the water grate frame (1) is installed has an included angle of 15 degrees with the vertical downward direction, and the lower edge of the water grate frame (1) is level with the road surface at the place, on the left side of the frame, Open five holes with a diameter of 1.5 cm at equal intervals on the right inner wall. The holes on the same side are on the same straight line. The center of the exposed end face of this thimble (2) is drilled with a conical pit, the taper of the pit is 120 °, and the depth is 5mm, between the thimbles of the same height on both sides, a movable baffle (3) is installed, and the movable baffle ( 3) It is a rectangular sheet with a thickness of 2mm. The extension body on the upper edge of the movable baffle...

The present invention provides a kind of lateral mosquito killing water grate for city sewer, and changes traditional horizontal water grate in the road into vertical water grate in the curbstone. The vertical water grate is provided with loose leaf board to break the passage of mosquito while ensure the rain water draining. Cutting off the life chain can kill mosquito radically. In addition, the present invention has also less material consumption and low cost.
Description
1. Technical field [0001] The present invention relates to the technology of killing mosquitoes in cities, in particular to a water grate with loose-leaf self-sealing boards installed on sidewalks on both sides of the road or on the side walls of green belts, so as to block the passage of mosquitoes in and out of the sewer, and finally cut off the life chain of mosquitoes A kind of water grate. 2. Background technology [0002] The simplest and most environmentally friendly technology to eliminate urban mosquitoes is to use a water grate that allows rainwater to pass through smoothly but mosquitoes cannot pass through. The applicant applied for it on November 19, 2003, and the patent number is: ZL200310110986X The name is urban sewer mosquito-killing water grate, and the application on December 30, 2005, the application number is 2005100224588, and the two technical solutions named urban sewer mosquito-killing water grate are all on the round hole type water grate skeleton p...
