Abstract

The utility model relates to a piston type sewer dredging device, comprising a cylinder in which a piston is positioned. A piston rod passes through the top cover of the cylinder. The end of the piston rod is provided with a pedal or a pressing plate. The bottom of the cylinder is provided with two interfaces. One of the interfaces is connected with a connecting nipple with a one-way valve and the connecting nipple is also connected with a water supply hose. The water supply hose is connected with the joint of a running water tap in a sealing way. The other interface is connected with a water outlet connecting nipple which is connected with a delivery hose. The delivery hose is connected with a hollow handle connected with a connecting base. The head of the connecting base is provided with a sealing device which is matched with the mould cavity at the port of the sewer in a sealing way. The utility model can be widely used for places which need dredging sewers, such as a family, public service and municipal projects.

Description

The piston type unbloking device for sewer

The utility model belongs to the mediation equipment of sewer pipe.

When sewer pipe blocked, things such as iron wire commonly used or bamboo chip were dredged, but sewer pipe has bend more, poor effect.Adopt rubber sucker, though cheap, easy to use, it is limited to remove effect, is not suitable for the non-planar pipeline opening especially, can not be effective as flush toilet etc.Adopt professional mediation equipment, though effect is good, cost an arm and a leg, incompatible general family purchases.Pipe-dredging liquid and for example must be with sewage emptying in the pond before using, and change money is also many.

The purpose of this utility model is the shortcoming at prior art, provides a kind of simple in structure, easy to manufacture, cheap, easy to use, dredges respond well unbloking device for sewer.

For achieving the above object by the following technical solutions:

The cylinder body that an inner wall smooth is arranged has a piston in the cylinder body, piston rod passes the cylinder body top cover, and there are a pedal or pressing board in the piston rod end.Cylinder base has two interfaces.Interface is chewed and is tightly connected with having connecing of one way valve, and this connects to chew with water supply hose and is tightly connected, water supply hose again with the joint sealing connection that is connected water tap; Another sealing joint connection water outlet connects chews, water outlet connects to chew with delivery hose and is tightly connected, the delivery hose other end hollow handle that is tightly connected, and the hollow handle endoporus is communicated with the delivery hose endoporus, handle is tightly connected with joint chair again, and joint chair head seal device and sewer mouth match.

Describe technical scheme and embodiment thereof in detail with reference to accompanying drawing:

Fig. 1 is the utility model overall structure schematic diagram.

A, b, c are three kinds of structural representations of the head seal device of joint chair 6 among Fig. 2.

As shown in Figure 1, piston 9 is housed in the cylinder body 10, piston rod 11 passes the cylinder body top cover, and there are pedal or pressing board (12) in the piston rod upper end.There is sealing 8 piston and inboard wall of cylinder block contact position.Two interfaces are arranged at cylinder body 10 bottoms.A sealing joint installation has connecing of one way valve and chews 3, and the spring force of this one way valve should be slightly less than common tap water pressure.Connect and chew 3 and be tightly connected with water supply hose 2, available pipe clamp is fastening, and water supply hose 2 other ends are tightly connected with the joint 1 that is connected water tap.Another sealing joint is installed to connect and is chewed 4, connects to chew 4 and be tightly connected with delivery hose 2 ', and same available pipe clamp is fastening.Delivery hose 2 ' other end and hollow handle 5 are tightly connected, and handle 5 is tightly connected with joint chair 6.The head of joint chair 6 is installed sealing device 7, and its size shape depends on the size shape of sewer mouth die cavity, as shown in the figure.Guarantee that joint chair and sewer mouth are sealed and matched.

The utility model is manipulated process:

Earlier joint 1 is connected on the water tap, joint chair 6 is pressed at sewer mouth with handle 5.Then, open water tap, hydraulic pressure is opened one way valve, and tap water is chewed 3 bottoms that enter cylinder body 10 from connecing, and general tap water is pressed in 1～3 kilogram/centimeter ², just can dredge for slight obstruction.When blocking comparatively seriously, answer pull-up piston 9, make cylinder body 10 retainings, firmly push down on the pedal again or pressing board 12, make to produce big pressure in the cylinder body, one way valve is promptly closed automatically, chews the water that 4 jets go out high hydraulic pressure from water outlet, immediately sewer pipe internal congestion thing can be washed away.For increasing hydraulic pressure, available pin impacts pedal 12, and effect is better.

The utility model advantage:

1, simple in structure, cheap, easy to use.

2, the dredging sewer pipe is respond well, is widely used, and is applicable to family, restaurant, factory and city's political and ideological work The fields such as journey.
