The draining device can prevent sundries as hairs and the like from blocking the filter cover to slow down water drainage, the water seal portion can achieve the purpose of primary deodorization, the second seal portion can achieve the purpose of secondary deodorization when accumulated water in the water seal portion is evaporated to fail in water sealing and deodorization after long-term absence of sewage drainage, and thereby the draining device is more complete in deodorization functions.

Description

Underground waterpipe dewatering installation

Technical field

The utility model relates to a kind of dewatering installation, particularly a kind of underground waterpipe dewatering installation.

Background technology

At present public floor drain adopts the filtering cover that has radial bar shaped filter bores usually, and this filtering cover covers on floor drain sealing shell, and filtering cover central authorities have the outfall of device-specific such as washing machine, and this outfall covers with removable cover when not using; The outfall and the sewer pipe of floor drain sealing outer casing bottom are tightly connected; Equipment draining pipe special is positioned in the floor drain sealing shell, and sewer pipe is inserted in its underpart; The upper end of equipment draining pipe special has the cover plate that is connected with its elasticity.There is following shortcoming in this floor drain: when draining, foreign material such as the hair in the sewage easily are piled up in filtering cover surface and the current drainage that slows down or block the surface water; Foreign material are only once filtered, and sewer pipe stops up easily; There is not deodorant function.

Summary of the invention

The technical problems to be solved in the utility model provides a kind ofly can be avoided filtering cover to stop up and slow down or block the big underground waterpipe dewatering installation of current drainage, filter area of the surface water.

In order to solve the problems of the technologies described above, underground waterpipe of the present utility model comprises filtering cover with dewatering installation, floor drain sealing shell; Described filtering cover covers on floor drain sealing shell, and the outfall and the sewer pipe of floor drain sealing outer casing bottom are tightly connected; Have a plurality of stripe-shaped filter bores that are parallel to each other and a plurality of groove vertical on the described filtering cover with the stripe-shaped filter bores.

During draining, sewage is discharged in the floor drain sealing shell by the stripe-shaped filter bores, and the outfall through floor drain sealing outer casing bottom enters sewer pipe again.In the drainage procedure, foreign material such as the hair in the sewage can be piled up in the groove place, can avoid filtering cover to stop up and the current drainage that slows down or block the surface water; And owing to have a plurality of grooves on the filtering cover, increased filter area, drainage speed is fast.

Underground waterpipe of the present utility model also comprise with dewatering installation have vertical bar shape filter bores, the bottom is the built-in filter of vertebra shape; Described built-in filter is positioned at the inside of floor drain sealing shell, and the edge of its upper end is stuck in the card of floor drain sealing shell upper inner surface along last, and the upper inside surface of built-in filter has projection.

Because built-in filter has vertical bar shape filter bores, the bottom is a vertebra shape, and filter area is big, the rate of filtration is fast; And the upper inside surface of built-in filter has projection, utilizes this projection easily built-in filter to be taken out, thus the foreign material that cleaning filters out.

The utility model utilizes filtering cover and built-in filter that foreign material are carried out double filtration, can reach the purpose of thorough filtration foreign material, thereby has guaranteed that further the sewer pipe current are unobstructed.

Underground waterpipe of the present utility model also comprises the taper manhole cover with dewatering installation, the once sealing gutter; Fixedly connected with the taper manhole cover in the bottom of built-in filter; The bottom of floor drain sealing shell is fixed with the once sealing gutter; The top of once sealing gutter is positioned at floor drain sealing shell, and sewer pipe is inserted in the bottom; The taper manhole cover covers on the once sealing gutter; Form water sealed tank between the sidewall of the bottom of the top of once sealing gutter and floor drain sealing shell and floor drain sealing shell.

The top of taper manhole cover, once sealing gutter and water sealed tank constitute water-sealing part jointly, and the ponding in the water sealed tank can prevent that foul smell returns more than the ground by the once sealing gutter in the sewer pipe, thereby reaches the deodorization purpose.

The bottom of described once sealing gutter has the secondary seal gutter, forms annular water tank between the bottom of secondary seal gutter and once sealing gutter, the secondary seal gutter supporting sephere secondary sealer that floats.

When water from the once sealing gutter when dirty, the water level in the ring-shaped groove rises gradually, and the spheroid secondary sealer is floated, current flow into sewer pipe by the secondary seal gutter.When sewage effluent not, the spheroid secondary sealer covers the upper end at the secondary seal gutter all the time.When causing the interior ponding of water sealed tank to be evaporated to the water-sealing stinking-proof disabler owing to long-time not sewage effluent, the spheroid secondary sealer can prevent that the foul smell in the sewer pipe from returning on the ground, thereby deodorant function is more perfect.

Be connected with the equipment draining pipe special that extends to ground on the sidewall of described floor drain sealing shell, the sealing screw lid is tightened in the top of equipment draining pipe special.

When not using indoor equipment such as washing machine, the sealing screw lid can be tightened in the top of equipment draining pipe special, seal this special-purpose outfall, and when finishing, it is embedded in lavatory ground line bottom.

Can be connected with cover plate in the sealing screw lid, cover plate adopts the link that has spring to be connected with the sealing screw lid.When not using equipment such as washing machine, cover plate covers on the outfall of equipment draining pipe special.During equipment such as use washing machine, cover plate can rotate, and the gutter of equipment inserts equipment draining pipe special.
