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.
The specific embodiment
As shown in Figure 1, 2, underground waterpipe of the present utility model comprises filtering cover 1 with dewatering installation, floor drain sealing shell 2, built-in filter 3, taper manhole cover 4, once sealing gutter 5, spheroid secondary sealer 6, secondary seal gutter 7, equipment draining pipe special 9.Described filtering cover 1 covers on floor drain sealing shell 2; Built-in filter 3 is positioned at the inside of floor drain sealing shell 2, and the edge 31 of its upper end is stuck in the card of floor drain sealing shell 2 upper inside surface along on 21, and the upper inside surface of built-in filter 3 has projection 32; Fixedly connected with taper manhole cover 4 in the bottom of built-in filter 3.The bottom and the once sealing gutter 5 of floor drain sealing shell 2 are structure as a whole, form water sealed tank 45 between the sidewall of the bottom of the top of once sealing gutter 5, floor drain sealing shell 2 and floor drain sealing shell 2, the top of taper manhole cover 4, once sealing gutter 5 and water sealed tank 45 common formation water-sealing parts.The bottom of floor drain sealing shell 2 has annular protrusion 22, forms ring-shaped groove between the bottom of once sealing gutter 5 and the annular protrusion 22, and insert in this groove the upper end of sewer pipe 8, and this groove is built-in with sealing ring 58.The bottom of once sealing gutter 5 has secondary seal gutter 7, forms annular water tank 57 between the bottom of secondary seal gutter 7 and once sealing gutter 5; Secondary seal gutter 7 unsteady supporting sephere secondary sealers 6.Be connected with the equipment draining pipe special 9 that extends to ground on the sidewall of described floor drain sealing shell 2, sealing screw lid 91 is tightened in the top of equipment draining pipe special 9.
Can be connected with cover plate 92 in the sealing screw lid 91, cover plate 92 adopts the link that has spring to be connected with sealing screw lid 91.
Have a plurality of stripe-shaped filter bores 11 that are parallel to each other and a plurality of groove 12 perpendicular to the stripe-shaped filter bores on the described filtering cover 1, the shape in groove 12 cross sections can be V-arrangement, trapezoidal or any reclinate shape of falling.
Described built-in filter 3 has the filter bores of vertical bar, finedraw, and its bottom is a vertebra shape.
The utility model is multiple functional, and filtration, draining and odor-resistant result are good, and be durable in use.Can select plastics is product processing raw material, and cost is low, can avoid using the metals such as copper of energy scarcity.
