Detailed Description
The present invention will be further described with reference to the accompanying drawings and embodiments.
Referring to fig. 1-3, in an embodiment of the present invention, a sewage shaft structure for municipal works includes: the sewage draining well 1 is of a rectangular structure; the collecting tank 2 is arranged on one side of the sewage well 1, and the collecting tank 2 is fixedly connected with the sewage well 1; the first filter screen 3 is arranged in the sewage well 1, and the first filter screen 3 is connected with the sewage well 1 in a sliding manner; the sundries collecting box 4 is arranged in the collecting tank 2 and is in sliding connection with the collecting tank 2; the impurity outlet 5 is arranged at one side of the sewage well 1; prevent the mechanism that flows backwards, prevent that the mechanism that flows backwards locates in the blowoff well 1, prevent that the mechanism that flows backwards includes four mount pads 6, four 6 fixed mounting of mount pad is in the blowoff well 1, four mount pad 6 is the rectangular array and distributes, four equal fixed mounting has spring 7 on the mount pad 6, 1 internal seal of blowoff well has closing plate 8, closing plate 8 with 1 sealing sliding connection of blowoff well, four the top of spring 7 all with closing plate 8 fixed connection.
Through setting up debris collecting box 4, realized concentrating the debris of crossing and accomodate, set up anti-backflow mechanism for also can not flow backwards and get into ground when the sewage in the blowdown well 1 flows backwards, influence pedestrian and vehicle past.
And the periphery of the inner wall of the sewage well 1 is provided with sewage discharge grooves 9.
Through setting up blowdown groove 9 for after closing plate 8 descends to certain degree, sewage flows to the below of closing plate 8 through blowdown groove 9.
The sundries collecting box 4 is provided with a sundries inlet 10, and the sundries outlet 5 is communicated with the sundries inlet 10.
The sewage draining well 1 is provided with a sewage draining hole 11, and the sewage draining hole 11 is in through connection with the sewage draining well 1 and the collecting tank 2.
The bottom of the sundries collecting box 4 is provided with a second filter screen 12, and the top of the sundries collecting box 4 is fixedly provided with two first handles 13.
Through setting up second filter screen 12, realized filtering the sewage and the debris that flow into in debris collecting box 4, set up two first in command 13 for clear up debris collecting box 4 convenient and fast more.
Two second handles 14 are fixedly arranged on the first filter screen 3.
By arranging two second handles 14, the first filter screen 3 can be cleaned and replaced more conveniently and quickly.
The bottom of the first filter screen 3 is provided with four supporting blocks 15, the four supporting blocks 15 are fixedly connected with the sewage well 1, and the four supporting blocks 15 are distributed in a rectangular array and are matched with the filter screen 3.
The four supporting blocks 15 play a role of fixing and supporting the first filter screen 3.
The utility model provides a theory of operation of blowoff well structure for municipal works as follows:
firstly, when sewage flows into the sewage well 1, the sewage is filtered by the first filter screen 3, the filtered sewage enters the sewage well 1, impurities filtered out at the moment can enter the impurity collecting box 4 through the impurity outlet 5 and the impurity inlet 10, a small amount of sewage is carried when the impurities enter the impurity collecting box 4, and the small amount of sewage flows into the sewage well 1 from the sewage discharge hole 11 through the second filter screen 12;
when sewage flows into bilge well 1 through first filter screen 3 in, sewage can concentrate on closing plate 8, when sewage on closing plate 8 reaches a certain amount, sewage can drive closing plate 8 compression spring 7 downstream by the effect of gravity, when closing plate 8 downstream arrives blowdown groove 9, sewage can flow into the lower part of blowoff well 1 through blowdown groove 9, when sewage on closing plate 8 flows into 1 lower part of blowoff well, spring 7 release elasticity promotes closing plate 8 upward movement, make closing plate 8 seal up blowoff well 1, at this moment, even sewage is too much below the blowoff well 1, can not make sewage flow backwards to the road surface yet.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
