Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1 and Figure 2, a kind of embodiment of the invention includes horizontally disposed cover board body 1, in the present embodiment,
The cross section of the cover board body 1 is rectangle, and the cover board body 1 is equipped with multiple be arranged in parallel and through the cover board body
The width direction of the bar shaped drainage hole 2 of 1 upper and lower end face, the length direction of the bar shaped drainage hole 2 and the cover board body 1 is flat
Row, the bottom end of the cover board body 1 are equipped with the shaft 3 perpendicular to 2 length direction of bar shaped drainage hole, the shaft 3
Both ends are fixed on the bottom end of cover board body 1 by fixing seat, and the shaft 3 is close to one end of the bar shaped drainage hole 2；Institute
State be rotatably connected in shaft 3 it is multiple be set side by side and with the length direction of the bar shaped drainage hole 2 blocked sewage bar disposed in parallel
4, multiple blocked sewage bars 4 be arranged in a one-to-one correspondence the bar shaped drainage hole 2 vertically below, multiple blocked sewage bars 4 away from
It is fixedly connected from the closer one end of the shaft 3 by connecting rod 5, multiple blocked sewage bars 4 are remote when rotating in the shaft 3
One end from the connecting rod 5, which is flipped up, stretches out the bar shaped drainage hole 2, one end by blocked sewage bar 4 far from connecting rod 5
It is promoted, leaf, the polybag etc. on 2 upper end of bar shaped drainage hole can be jacked up, avoid resulting in blockage to bar shaped drainage hole 2；It is described
Connecting rod 5 is equipped with chaining 6, and the chaining 6 is located at the middle part of the connecting rod 5, and the top of chaining 6 and the rotation of connecting rod 5 connect
It connects, the water receiver 7 that top can be injected for rainwater is linked on the chaining 6, the bottom end of the water receiver 7 is equipped with discharge outlet 8.
As shown in figure 3, the preferred embodiment of the invention includes: the bottom of the one end of the blocked sewage bar 4 far from the connecting rod 5
Portion is equipped with blocked sewage secondary bar 9, and one end of the blocked sewage secondary bar 9 is fixedly connected with the bottom of the blocked sewage bar 4, the blocked sewage bar 4
When one end far from the connecting rod 5 is flipped up the stretching bar shaped drainage hole 2, the blocked sewage secondary bar 9 is far from the blocked sewage
One end of bar 4 is located in one end of the bar shaped drainage hole 2.After blocked sewage bar 4 is promoted far from one end of connecting rod 5, infusion, modeling
The sundries such as material bag may or drop on one end after blocked sewage bar 4 is promoted and the bar shaped drainage hole 2 between cover board body 1, pass through
Blocked sewage secondary bar 9 is set, leaf, polybag, paper scrap etc. is avoided to block the bar shaped drainage hole 2 below the end, improves anti-clogging effect；
Preferably, blocked sewage secondary bar 9 is arranged close to the end of the described one end of blocked sewage bar 4 far from connecting rod 5, and in blocked sewage bar 4 far from even
After one end of extension bar 5 promotes certain altitude, the blocked sewage secondary bar 9 is pressed on the end of bar shaped drainage hole 2 far from one end of blocked sewage bar 4
Portion bottom is realized and realizes restriction to the hoisting depth of blocked sewage bar 4.
As shown in figure 3, preferred embodiment are as follows: be located at two blocked sewage bars 4 of two sides in multiple blocked sewage bars 4
Bottom is equipped with side block dirt bar 10, and the side block dirt bar 10 is located between the shaft 3 and the blocked sewage secondary bar 9, the side block
One end of dirty bar 10 is fixedly connected with the bottom of the blocked sewage bar 4.The setting of side block dirt bar 10 can be in blocked sewage bar 4 far from connecting rod
After 5 one end is promoted, the two sides for the blocked sewage bar 4 being set side by side are stopped, avoid leaf, polybag, paper scrap etc. from two sides
The top for entering bar shaped drainage hole 2 blocks it.The side block dirt bar 10 is vertically arranged with the blocked sewage bar 4 or institute
The one end of side block dirt bar 10 far from the blocked sewage bar 4 is stated to be obliquely installed to the direction of the blocked sewage secondary bar 9.Side block dirt bar 10 is vertical
It is arranged or is obliquely installed to the direction for being biased to blocked sewage secondary bar 9, it is ensured that the effect of blocking.
It is further preferred that being equipped with the regulating valve 11 for adjusting drainage speed at the discharge outlet 8.Regulating valve 11 is set
The speed that can adjust the draining of water receiver 7 as needed is set, realizes that blocked sewage bar 4 can be elevated in different rainfall, improves suitable
The property used.As shown in figure 4, the top of the water receiver 7 is equipped with water receiving opening 12, it is equipped with filter screen 13 at the water receiving opening 12,
The middle part of the filter screen 13 is fixed with hook 14, and the hook 14 is hung on the chaining 6, by the way that filter screen is arranged
13, the spot entered in water receiver 7 is reduced, the weight of water receiver 7 is that the weight of water receiver 7 is added from 12 entrance of water receiving opening
Amount of rainfall subtract the water drained from discharge outlet 8, when water receiving amount is greater than displacement, the weight of water receiver 7 just be will increase, logical
Regulating valve 11 is overregulated, to realize adjusting drainage speed.
Further preferred embodiment are as follows: the upper surface of the blocked sewage bar 4 is equipped with for showing the blocked sewage bar 4 upwards
Stretch out the warning strip 15 of the overhang of the bar shaped drainage hole 2.The setting of warning strip 15 can be intuitive after blocked sewage bar 4 is elevated
Amount of rainfall is judged on ground, and can realize and warn to passerby after being elevated in blocked sewage bar 4.In an embodiment of the present invention, institute
State warning strip 15 can be using luminous patch or being illustrated, such as from one end of close shaft 3 to separate by different colors
Green, yellow and red paint are successively brushed in one end of shaft 3, realize the function of warning.
Working principle: when not having rainwater or rainwater is less, 4 longer sections of blocked sewage bar is supported because self weight lets droop by connecting rod 5
It is pressed in the bottom end of cover board body 1, it is parallel with bar shaped drainage hole 2；When encountering torrential rain, rainwater flows into water receiver 7, and (inflow is big
In 8 displacement of discharge outlet), when water receiver 7 be filled with water weight be more than the one end of blocked sewage bar 4 far from connecting rod 5 weight when, blocked sewage bar
4 are just erected by drawing automatically, and can effectively block water flow by the setting of blocked sewage secondary bar 9 and side block dirt bar 10 and break through
Polybag, paper, the leaf etc. come；When rainfall reduces or stops, the water in water receiver 7 is lost through bottom discharge mouth 8, blocked sewage
The weight of the one end of bar 4 far from connecting rod 5 is more than the weight of water receiver 7, connecting rod 5 and blowdown bar close to one end of connecting rod 5
Amount, blowdown bar just restores automatically and 8 parastate of discharge outlet, is not required to artificially go to handle.
The beneficial effects of the present invention are: the present invention utilizes the gravity of rainwater, when rainy, rainwater is fallen into water receiver 7, is connect
7 gravity of water box increases to decline, drives blocked sewage bar 4 to be lifted up far from one end of connecting rod 5, by the tree on bar shaped drainage hole 2
Leaf, polybag, paper scrap, mudstone etc. jack up, and avoid resulting in blockage to bar shaped drainage hole 2, solve blockage problem, solve because of discharge outlet
8 block caused urban waterlogging, and at low cost, effect is preferable.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
