Abstract

The utility model discloses a dredger used for removing foreign matters which clog a sewage main pipe. The utility model is arranged in the water inlet of a container (such as a toilet bowl). The dredger is composed of a water retaining ring (3), a bulkhead (2) and a sealing ring (4). The bulkhead (2) is spirally connected with the inner wall of the water retaining ring. The sealing ring is appressed to a step (9) and is sheathed on the outer wall of the water retaining ring. The sealing ring is clamped between the inner wall of a container (12) and the outer wall of the water retaining ring. The space at the upper part of the sealing ring is filled with cement mortar. When a sewage main pipe is clogged, water which is accumulated at the upper part of foreign matters which clog the sewage main pipe gradually rises, which forms a water level difference. The foreign matters which clog the sewage main pipe are crushed by water column pressure, and the sewage main pipe is dredged.

Description

The automatic dredging device of multifunctional pipe

The utility model relates to the utensil of getting rid of the sewer pipe obstruction, is the automatic dredging device of a kind of multifunctional pipe.

In the high residential building building, the shared same following water trunk line of some resident families, if article such as the discarded object of the chicken and duck flesh of fish, cotton yarn, clothing fall into the lavatory pan water inlet of washroom, they may stay down water trunk line bottom or corner, cause down the water trunk line to stop up, in this way, the sewage in the pipeline will flow backwards from the washroom lavatory pan of building bottom resident family and enter the room, and this just need employ dredging machine and get rid of obstruction.Dredging machine commonly used is a kind of machine that has the spring flexible axle, and the spring flexible axle is inserted in the pipeline, makes its rotation stir loose obstruction, can reach the mediation purpose.But the dredging machine of this structure often needs the professional to operate owing to use trouble, and the mediation process wastes time and energy influences resident family's domestic hygiene, and function singleness, the price of this dredging machine are more expensive simultaneously.

The purpose of this utility model is to provide a kind of simple to operate, automatic dredging device of multifunctional pipe that clean hygiene can in time be got rid of obstruction.

The automatic dredging device of the multifunctional pipe that the utility model provides is installed in the container water inlet.This dredging device is made up of retaining ring, plug and sealing ring.Retaining ring is one section short tube, and its longitudinal section shape is: inwall is rectangle, outer wall is trapezoid, inwall is provided with screw thread, outer wall is provided with groove, the bottom is provided with step.Sealing ring is close to the step upper surface and is entangled the retaining ring outer wall, is stuck between container inner wall and the retaining ring outer wall.The plug that has handle is screwed onto on the inwall of retaining ring.This dredging device utilizes hydraulic coupling eliminating obstruction to reach the mediation purpose.When water trunk line bottom or corner are blocked instantly, building bottom resident family can screw in plug the retaining ring inwall, sewage will accumulate at the obstruction upper space, water level rises and forms water-head, accumulate water and will produce a suitable active force to obstruction, this active force makes local the becoming flexible of obstruction be brought into municipal sewage system until whole obstructions by current.

According to above-mentioned dredging device, its retaining ring bottom is provided with axle bed, and the earrings of torsion spring and watertight shutter is enclosed within on the axle, and this is fixed in the hole of described axle bed, forms a device that stops to spatter on the effluent sewerage.

The utility model utilizes hydraulic coupling mediation sewer pipe, do not need electric power, without flexible axle, simple in structure, easy to operate, mediation is timely, cheap, clean hygiene, precautions averts perils.Can adapt to the family life demand, and have the effect stifled smelly, that waterproof is spattered.

Below in conjunction with the drawings and specific embodiments the utility model is described in further details:

Fig. 1 is the elevational cross-sectional view of the utility model dredging device specific embodiment.

Fig. 2 is the upward view of dredging device shown in Figure 1.

Fig. 1 has provided a kind of concrete structure of dredging device.This dredging device has the retaining ring 3 of a short tube type, and the longitudinal section shape of this retaining ring is: inwall is rectangle, outer wall is trapezoid, the top of outer wall 14 is provided with groove 11, the bottom is provided with step 9.The upper surface that the whippy sealing ring of making of rubber 4 is close to step 9 entangles the outer wall of retaining ring 3.The external diameter of sealing circle makes firm being stuck between container inner wall and the retaining ring outer wall of sealing ring greater than container 12 internal diameters 2 millimeter.The sealing ring upper space fills up cement mortar 13, owing to be provided with groove 11, trapezoidal outer wall has certain tapering, and mortar, retaining ring and container inner wall are solidified as integrally formed self-locking, have increased longitudinal frictional force, has improved stability is installed.

As shown in Figure 1, the retaining ring inwall is provided with screw thread 10 and is screwed onto on the retaining ring inwall for plugs 2 and seals current, utilizes the side screw that handle 1 is fixed on the plug middle part, is convenient to the plug advance and retreat.

Referring to Fig. 2, be provided with axle bed 8 on two in the bottom of retaining ring 3, the earrings of torsion spring 6 and watertight shutter 5 is enclosed within on the axle 7, and axle 7 is fixed in the hole of axle bed 8.Have spilling water groove 15 on the side of watertight shutter 5, a small amount of sewage can flow into sewer through groove 15.Watertight shutter 5 can stop on the effluent sewerage and spatters.

Be example now, its using method and mediation principle are described in the building bottom resident family washroom lavatory pan water inlet dredging device to be housed.

Plug is not installed during normal the use, and sewage flows into sewer through retaining ring inwall and spilling water groove 15, and when discharge was big, watertight shutter 5 was washed open, and current are unblocked.

Once stop up, be that obstruction rests on down water trunk line bottom or corner, resident family can screw in plug the retaining ring inwall, the sewage of following water trunk line can not overflow to the washroom, and must accumulate in the upper space of obstruction, when accumulating water column and reaching 3 meters left and right sides, under the water column pressure effect, obstruction is scattered by pressure than vulnerable area, and subsequently, whole obstruction is washed away the inflow municipal sewage system.

Be applied to the size of the active force on the obstruction, be decided by water-column, can the obstruction that crush also relevant with the friction of the density of obstruction and it and tube wall.But if second floor, the 3rd buildings even each floor resident family all use this dredging device, then water-column successively strengthens, in the ordinary course of things, and the water column pressure obstruction that can crush.

The retaining ring of this dredging device, plug, handle and watertight shutter are preferably selected plastic products for use.
