Abstract
The utility model relates to an improved drain grid device which is arranged at the water inlets of sewers at both sides of a road for draining rain water. The utility model is characterized in that a cast iron grid is connected with a concrete frame through a shaft, the cast iron grid on the drain grid device is effectively protected against being taken off and being stolen, and the cast iron grid is upwards lifted without influencing desilting operation and desludging operation.
Description
The utility model is a kind of improved, uses the comb water device at the sewer water inlet place of draining rainwater on both sides of the street.
Drain the comb water device of the sewer water inlet place use of rainwater at present on the road, its concrete frame separates with the cast iron double-edged fine-toothed comb.The cast iron double-edged fine-toothed comb is taken off by the people easily and steals, thereby influences the safety of pedestrian's driving.
The purpose of this utility model is that a kind of improved comb water device will be provided, and its can effectively prevent to comb cast iron double-edged fine-toothed comb on the water device is removed and steals, thereby guarantees the safety of pedestrian's driving.
The purpose of this utility model is achieved in that an end of the concrete frame on comb water device stays upper shaft hole, end on the cast iron double-edged fine-toothed comb is cast upper shaft hole again, cast iron double-edged fine-toothed comb and concrete frame are connected together by axis hole with a metal shaft, constitute an integral body, place the sewer water inlet place of draining rainwater on the road.
Because by adding axle, the cast iron double-edged fine-toothed comb has been connected in concrete frame, the cast iron double-edged fine-toothed comb both had been difficult for being removed stealing like this, can on axially, start again, do not influence the carrying out of desilting scrubbing work, and axle is big slightly with the gap of axis hole cooperation place on the cast iron double-edged fine-toothed comb, can become rusty extremely to influence and lift.
Below in conjunction with accompanying drawing structure of the present utility model is further described:
Fig. 1 is a stereogram of the present utility model.
Fig. 2 is an assembling drawing of the present utility model.
Referring to Fig. 1, this device has the concrete frame (1) of axis hole by one one end, a cast iron double-edged fine-toothed comb (2) that has axis hole, and a metal shaft (3) constitutes.By metal shaft cast iron double-edged fine-toothed comb and concrete frame are connected together.When this device was placed sewer water inlet place, its cast iron double-edged fine-toothed comb can upwards start and be difficult for being removed.
Claims (3)
1, a kind of improved, use the comb water device at the sewer water inlet place of draining rainwater on both sides of the street.This device has a concrete frame (1) that has axis hole, a cast iron double-edged fine-toothed comb (2) and a metal shaft (3) that has axis hole.It is characterized in that cast iron double-edged fine-toothed comb (2) and concrete frame (1) being connected together by metal shaft (3).
2, device according to claim 1 is characterized in that the cast iron double-edged fine-toothed comb (2) that has axis hole can start on axially.
3, device according to claim 1 is characterized in that having axis hole on the concrete frame (1).
