Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, it is a preferred embodiment of the present invention. This drainage device suitable for road drainage can be used to municipal administration ground road and elevated highway section road, and the elevated highway section road is taken as the example to expand the explanation in this embodiment:

specifically, this drainage device includes the drainage chamber 1 that sets up along road extending direction, and 1 inside wall of drainage chamber has annular interior step, and drainage chamber 1 is close road surface department and has water inlet 11, and water inlet 11 is higher than road surface department setting with the help of first wall 13 above this step, and the vertical setting in first wall 13 relative road surface avoids debris to arouse water inlet 11 to block up, avoids debris to get into in the drainage chamber 1 from the source and leads to blockking up. The bottom of the drainage chamber 1 is provided with a drainage port 12 communicated with a rainwater pipe, and a switch part 3 capable of opening or closing the drainage port 12 is arranged in the drainage chamber 1, so that the drainage chamber can be opened to quickly drain water when the rainfall is overlarge, and road ponding is avoided. In addition, the part between the top and the bottom of switch member 3 is well kenozooecium 33, and the setting of this well kenozooecium 33 can reduce the density of switch member 3, makes its density be less than water to when having ponding, buoyancy and the second magnetic member that produce at ponding produce float under the effect to the ascending magnetic attraction of switch member 3 to open outlet 12, promote the discharge of ponding.

In order to quickly drain water when the rainfall is too large, the concept of "one-block-prevention two-drainage" is integrated for this embodiment, and from the viewpoint of skillful structural realization, the switch piece 3 is arranged on the second wall surface 14 below the step in a magnetic attraction manner, the second wall surface 14 is horizontally arranged relative to the road surface, and the drainage port 12 is closed in a state where the switch piece 3 is arranged on the second wall surface 14. When the rainfall is too large, in order to enable the switch member 3 to open the water outlet 12, from the perspective of simple structure, the second wall surface 14 of the embodiment is provided with the first magnet 4, correspondingly, the bottom of the switch member 3 is provided with the first iron sheet 31 which is attracted with the first magnet 4, so that the switch member 3 can be closed by being attracted with the second wall surface 14 of the annular inner step, the first iron sheet 31 also has a second function, the weight of the switch member 3 can be increased, and the switch member 3 can be assisted to fall back to the second wall surface 13 of the annular inner step again under the state that accumulated water in the drainage chamber 1 is drained, so that the function of locking is realized. The arrangement of the annular inner step in the drainage chamber 1 enables the first wall surface 13, which is higher than a road surface, of the annular inner step to be used for arranging the water inlet 11, so that the water inlet 11 is naturally higher than the road surface to achieve the effect of preventing sundries from blocking, the second wall surface 14 of the annular inner step also achieves the effect of achieving 'one object and two purposes', namely the effect of supporting the switch piece 3, the drainage port 12 is closed in the state that the switch piece 3 is arranged on the second wall surface 14, and when the rainfall is too large, the switch piece 3 can open the drainage port 12 to achieve the effect of rapidly draining water into a rainwater pipe so as to achieve the effect of accelerating the 'two drainage' of the rainwater.

Correspondingly, the top of the drainage chamber 1 of the embodiment also needs to be capable of keeping the switch 3 on an acting element arranged thereon, the switch 3 is magnetically attracted by the first iron sheet 31 and the first magnet 4 of the second wall surface 14 to close the drainage port 12, the top of the drainage chamber 1 also adopts a magnetic attraction manner to attract the switch 3 to be in a state of opening the drainage port 12, specifically, the switch 3 is also arranged on the top of the drainage chamber 1 through a magnetic attraction manner, and the drainage port 12 is opened in a state of attracting the switch 3 on the top of the drainage chamber 1. In order to realize that the top of the drainage chamber 1 can magnetically attract the switch component 3, and from the structural simplicity, the top of the drainage chamber 1 is provided with the second magnet 2, and correspondingly, the top of the switch component 3 is provided with the second iron sheet 32 attracted with the second magnet 2.

In summary, the working process of the road drainage system is as follows:

A. when no water is accumulated in the drainage chamber 1, the water outlet 12 cannot be opened because the magnet attraction force generated at the top of the drainage chamber 1 is less than the weight of the upper and lower iron sheets (namely the first iron sheet 31 and the second iron sheet 31) of the switch part 3, so that the phenomenon that earth, gravel and the like enter the drainage chamber 1 to cause blockage by a sweeper and the like can be avoided.

B. When water is accumulated (the height of the accumulated water is more than or equal to 3 cm), the water enters the drainage chamber 1 and generates buoyancy, the magnetic attraction on the top of the drainage chamber 1 is assisted to clamp the switch piece, the accumulated water is discharged through the water outlet 12, and the applicant needs to emphasize that when the switch piece 3 is in a state of being magnetically attracted by the top of the drainage chamber 1, the accumulated water always exists in the whole drainage chamber 1 (the water inlet speed of the accumulated water is higher than the water outlet speed of the water outlet 12), namely the switch piece 3 is always soaked in the accumulated water, and at the moment, the buoyancy force borne by the switch piece 3 plus the magnetic attraction force of the top of the drainage chamber 1 to the switch piece = the gravity of the switch piece 3;

C. when the accumulated water is gradually discharged from the water outlet 12, the accumulated water amount of the water discharging chamber 1 is reduced, the switch piece 3 is soaked in the accumulated water, at the moment, the buoyancy force applied to the switch piece 3 is eliminated, at the moment, the magnetic attraction force generated at the top of the water discharging chamber 1 is less than the weight of the upper iron sheet and the lower iron sheet (namely the first iron sheet 31 and the second iron sheet 31) of the switch piece 3, therefore, the switch piece 3 can fall back to the second wall surface 14 again, the 'drop lock' is generated, and the water outlet 12 is closed again.
