Town road drainage seat
Technical field
The utility model relates to a kind of town road drainage seat.
Background technology
In town road, can arrange the lower section of the drainage seat discharge for rainwater, particularly physical features, the drainage seat quantity of setting is more.But these drainage seats in use, its openings of sizes is fixed often, and displacement is also fixing, therefore when running into different discharge values, also need corresponding change for displacement, when running into flood weather, the drainage seat of these fixed displacements can not meet drainage requirement at all.
Summary of the invention
Technical problem to be solved in the utility model is to provide simple, the adjustable displacement size of a kind of structure, there will not be the town road drainage seat of blocking.
The utility model is achieved through the following technical solutions: a kind of town road drainage seat, comprise the drainage seat being installed on sewer mouth, the bottom of sewer mouth arranges drainage pipe, described drainage seat comprises a main water inlet tube, described main water inlet tube communicates with drainage pipe inner chamber through drainage pipe upper end, the both sides of main water inlet tube respectively arrange an auxiliary water inlet pipe, auxiliary water inlet pipe buckles into and is arranged in cement layer, the cross section of auxiliary water inlet pipe is a square structure, the upper surface of auxiliary water inlet pipe arranges a web plate, the lower end of web plate arranges a sealing plate, web plate is by the inlet opening on sealing plate sealing web plate, be positioned at auxiliary water inlet pipe and one piston rod is set, piston rod is inner to cement layer through auxiliary water inlet pipe, the outboard end being positioned at piston rod arranges a foam-rubber cushion, the end of foam-rubber cushion and piston rod offsets, the other end of described piston rod arranges a baffle plate, the whole auxiliary water inlet pipe inner chamber of baffle plate transverse sealing, be positioned on sealing plate and a buckle is set, buckle and baffle plate side offset, communicate between main water inlet tube with auxiliary water inlet pipe.
As preferably, the lower end of described auxiliary water inlet pipe is provided with more than one intubate, and intubate communicates with drainage pipe inside through drainage pipe.
As preferably, the upper end of described drainage seat arranges a protective cover, and described protective cover is positioned at the upper end of main water inlet tube and auxiliary water inlet pipe, the rounded shape of whole protective cover, and protective cover one circle is provided with more than one water inlet.
As preferably, described sealing plate is made up of hard plastics.
The beneficial effects of the utility model are: the utility model is when running into flood situation, owing to filling water in main water pipeline, therefore the water filled is owing to having little time to discharge the auxiliary water inlet pipe just washing left and right sides open, sealing plate on auxiliary water inlet pipe is opened, and then increase the openings of sizes of whole drainage seat, increase displacement.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Coding in figure is respectively: 1 is foam-rubber cushion, and 2 is auxiliary water inlet pipe, and 3 is piston rod, and 4 is protective cover, and 5 is sealing plate, and 6 is web plate, and 7 is baffle plate, and 8 is main water inlet tube, and 9 is buckle, and 11 is drainage pipe, and 12 is intubate.
Detailed description of the invention
As shown in Figure 1, this town road drainage seat, comprise the drainage seat being installed on sewer mouth, the bottom of sewer mouth arranges drainage pipe 11, described drainage seat comprises a main water inlet tube 8, described main water inlet tube 8 communicates with drainage pipe 11 inner chamber through drainage pipe 11 upper end, the both sides of main water inlet tube 8 respectively arrange an auxiliary water inlet pipe, auxiliary water inlet pipe 2 is arranged in cement layer, the cross section of auxiliary water inlet pipe 2 is a square structure, the upper surface of auxiliary water inlet pipe 2 arranges a web plate 6, the lower end of web plate 6 arranges a sealing plate 5, web plate 6 seals the inlet opening on web plate 6 by sealing plate 5, be positioned at auxiliary water inlet pipe 2 and a piston rod 3 is set, piston rod 3 is inner through auxiliary water inlet pipe 2 to cement layer, the outboard end being positioned at piston rod 3 arranges a foam-rubber cushion 1, foam-rubber cushion 1 offsets with the end of piston rod 3, the other end of described piston rod 3 arranges a baffle plate 7, whole auxiliary water inlet pipe 2 inner chamber of baffle plate 7 transverse sealing, be positioned on sealing plate 5 and a buckle 9 is set, buckle 9 and baffle plate 7 side offset, communicate between main water inlet tube 8 with auxiliary water inlet pipe 2.
Wherein, the lower end of auxiliary water inlet pipe 2 is provided with more than one intubate 12, and intubate 12 communicates with drainage pipe 11 inside through drainage pipe 11, and the water in auxiliary water inlet pipe 2 flows in drainage pipe 11 by intubate 12, increases discharge value.
Wherein, the upper end of drainage seat arranges a protective cover 4, and described protective cover 4 is positioned at the upper end of main water inlet tube 8 and auxiliary water inlet pipe 2, the rounded shape of whole protective cover 4; protective cover 4 one circle is provided with more than one water inlet, and the Main Function of protective cover 4 is exactly the blocking in order to prevent water inlet.
Wherein, sealing plate 5 is made up of hard plastics, when there is the situation of small displacement at ordinary times, sealing plate 5 is sealing web plate 6 all the time, when main water inlet tube 8 internal drainage amount is excessive, current enter auxiliary water inlet pipe 2, are extruded by baffle plate 7 toward outside, piston rod 3 is moved laterally, foam-rubber cushion 1 compresses, and baffle plate 7 drives the outside side of whole sealing plate 5 to move by buckle 9, and whole web plate 6 is opened, increase upper end open, and then increase displacement.
The beneficial effects of the utility model are: the utility model is when running into flood situation, owing to filling water in main water pipeline, therefore the water filled is owing to having little time to discharge the auxiliary water inlet pipe just rushing at left and right sides, sealing plate on auxiliary water inlet pipe is opened, and then increase the openings of sizes of whole drainage seat, increase displacement.
