Detailed Description

A bridge floor drainage mechanism is shown in figure 1 and comprises a drainage opening 1 vertically formed in the upper surface of a bridge floor, a drainage pipe 2 fixedly connected with a lower port of the drainage opening 1, an annular containing object 3 detachably connected in the drainage opening 1, and a drainage sieve 4 arranged at the upper port of the drainage opening 1.

As shown in fig. 1 and 2, the drain opening 1 is a circular hole. A bearing ring 11 for bearing a ring 11-shaped object containing piece is arranged in the water outlet 1, the bearing ring 11 is horizontally arranged, and the outer peripheral surface of the bearing ring 11 is fixedly connected with the inner peripheral surface of the water outlet 1. The annular holding member 3 comprises a support tube 31 with a vertical axis, and an annular supporting plate 32 fixed at the lower end opening of the support tube 31. The diameter of the outer peripheral surface of the support pipe 31 is equal to the diameter of the drain opening 1; the annular supporting plate 32 is arranged in the supporting pipe 31, the annular supporting plate 32 extends to the middle direction of the upper port of the supporting pipe 31 away from the port connected with the supporting pipe 31, so that an annular groove 33 is formed between the supporting pipe 31 and the annular supporting plate 32, and the position of the upper port of the annular supporting plate 32 is lower than that of the upper port of the supporting pipe 31, so that rainwater is accumulated to be overfull and can flow out from the upper port of the annular supporting plate 32. When the annular container 3 is installed in the drain opening 1, the support tube 31 is inserted into the drain opening 1 from the upper end opening of the drain opening 1, and the lower end opening of the support tube 31 is supported on the upper surface of the support ring 11.

As shown in fig. 2 and 3, the upper port of the annular supporting plate 32 is provided with a filter screen 5, the filter screen 5 is uniformly provided with a plurality of meshes 51, the filter screen 5 is tapered, the tip of the filter screen 5 is arranged upward, the port of the filter screen 5 is fixedly connected with an annular limiting ring 52, and the upper port of the annular supporting plate 32 is provided with a limiting groove 321 which is matched with the limiting ring 52, so that the filter screen 5 can be stably covered on the annular supporting plate 32. When the filter screen 5 and the annular supporting plate 32 are matched with each other, the filter screen 5 and the annular supporting plate 32 form a cone with an upward pointed end.

As shown in fig. 1 and 2, when rainwater flows into the drain opening 1 from the edge of the drain opening 1, large floating objects in the rainwater are blocked by the drainage screen 4 and isolated on the bridge floor, and the rainwater and other impurity garbage flow into the annular groove 33 along the inner wall of the drain opening 1, so that the heavy soil and impurities are accumulated at the bottom of the annular groove 33; and the impurity that the quality is lighter can be along with the rainwater in annular groove 33 pile up and slowly come up, when the rainwater reachd the height of filter screen 5, the rainwater can flow out from the mesh 51 of filter screen 5, and the diameter is greater than the impurity rubbish of filter screen 5 mesh 51, can pile up in annular groove 33 under the filter action of filter screen 5 to the convenience carries out centralized processing to the rubbish in the annular groove 33. The situation that the drain pipe 2 is blocked due to the fact that the impurity garbage flows into the drain pipe 2 is also avoided.

As shown in fig. 1 and 4, an installation groove 12 for accommodating the drainage sieve 4 is formed at the edge of the drainage opening 1. After the drainage sieve 4 is placed in the mounting groove 12, the upper surface of the drainage sieve 4 is kept flush with the bridge floor, and the smoothness of the bridge floor is guaranteed. A plurality of water holes 41 are evenly formed in the upper surface of the drainage sieve 4, so that the rainwater can normally pass through the drainage sieve, and meanwhile, the separation effect on massive impurity garbage can be achieved. A water collecting hole 42 has been seted up with the position that filter screen 5 pointed end corresponds in the middle part of drainage sieve 4, and the rainwater falls in filter screen 5's pointed end department through water collecting hole 42, because filter screen 5's pointed end up, so the rainwater can be along filter screen 5 global think annular groove 33 in erode to reduced piling up of filter screen 5 surface impurity, ensured filter screen 5 mesh 51 unobstructed, and the impurity of dashing away can be collected in annular groove 33, the centralized processing of being convenient for. The lower surface of drainage sieve 4 is fixedly connected with annular water diversion plate 6, the port of water diversion plate 6 is fixedly connected at the edge of water collecting hole 42, the diameter of the lower port of water diversion plate 6 is smaller than the diameter of water collecting hole 42, and the lower port of water diversion plate 6 points to the tip of filter screen 5. When rainwater flows into the water collecting holes 42, the aperture of the lower end opening of the water diversion plate 6 is smaller than that of the water collecting holes 42, so that the rainwater flows out from the water diversion plate 6 more intensively, and the effect of the rainwater on the surface scouring of the filter screen 5 is more obvious.

As shown in fig. 2, a plurality of needle pillars 7 are disposed on the circumferential surface of the annular supporting plate 32 facing the supporting tube 31, the needle pillars 7 are disposed at positions close to the upper end of the annular supporting plate 32 and are uniformly distributed along the annular direction of the annular supporting plate 32, one end of each needle pillar 7 is fixedly connected to the annular supporting plate 32, and the other end of each needle pillar 7 is set to be a tip. Impurity when the rainwater in flows into annular groove 33 back along the inner wall of outlet 1, along with the rainwater is ascending at the horizontal plane in annular groove 33, the rubbish that the quality is lighter also can follow the rising of the surface of water and rise, the subassembly that blocks that the setting of needle post 7 played the rubbish that the quality is lighter, the rubbish that the quality is lighter is reduced and is blocked the filtration pore, if there are flexible rubbish such as some disposal bags, the disposal bag can twine on needle post 7 at the in-process that the surface of water flows, thereby the condition that flexible rubbish blocks filter screen 5 has been reduced takes place, and also be convenient for the staff carries out centralized processing to rubbish.

As shown in fig. 2, two holding rods 8 are fixedly connected to the inner circumferential surface of the supporting tube 31, and when a worker intensively treats the garbage in the drain opening 1, the holding rods 8 are arranged so that the worker can conveniently take out the annular container 3 from the drain opening 1 for centralized treatment by lifting the holding rods 8.

The working process is as follows: the staff firstly puts into outlet 1 from the last port of outlet 1 annular flourishing thing 3 to make the stay tube 31 support on bearing ring 11, then puts drainage screen 4 in mounting groove 12, if in rainy season, the rainwater can enter into outlet 1 through the border of outlet 1, be greater than the rubbish of drainage screen 4 water-through hole 41 in the rainwater can be filtered on the bridge floor, remaining rubbish can enter into outlet 1, rainwater and remaining rubbish can flow into annular groove 33 along the inner wall of outlet 1, along with the piling up of rainwater in annular groove 33, the rainwater can flow out from the mesh 51 of filter screen 5, and the impurity of heavier weight can deposit the bottom in annular groove 33, and the rubbish of lighter weight can receive the hindrance of styletable 7 to collect in annular groove 33, be convenient for the staff to carry out centralized processing to rubbish.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
