Dredging device special for downcomer

Abstract

The invention relates to a downcomer dredging structure, in particular to a dredging device special for a downcomer. The dredging device comprises a dredging metal hose and a taper positioning plug sleeves the dredging metal hose; two ends of the dredging metal hose are fixedly provided with a two-way pipe connector and a T-pipe connector respectively; one end of the two-way pipe connector and thetail end of the dredging metal hose are fixed into a whole, and the other end of the two-way pipe connector is fixedly provided with a plugging positioning mechanism; the dredging metal hose is internally provided with an air supply hose and a conductive cable; one end of the conductive cable passes through a third end opening of the T-pipe connector and then is fixed with a connection-peg into awhole, the other end of the conductive cable passes through the plugging positioning mechanism and then is electrically connected with an electric heater, and the electric heater is located in an airgenerator. The dredging device special for the downcomer has the advantages of shortening dredging time, operating simply, avoiding damage to a pipe wall, reducing dredging cost and improving life quality.

Description

technical field [0001] The invention relates to a dredging structure for a sewer pipe, in particular to a special dredger for a sewer pipe which shortens the dredging time, is easy to operate, does not damage the pipe wall, reduces the dredging cost and improves the quality of life. Background technique [0002] In daily life, sewer pipes are widely used in drainage areas such as kitchens and toilets for drainage. With the passage of time when the sewer pipes are in use, people will inevitably have the problem of sewer pipe blockage in their lives. Once the sewer pipe is blocked, it will bring great inconvenience to people's life. When it is seriously blocked, the sewage will overflow the floor drain, pollute the kitchen or toilet, and affect people's daily life and work. This is especially true where public toilets are required. [0003] In order to solve the problem of sewer blockage, people have designed various dredging tools, one is the machine dredger, which has a go...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of sewer blockage, people have designed various dredging tools, one is the machine dredger, which has a good dredging effect, but it is expensive to use and inconvenient to operate, and is generally not used for household use except in special circumstances; the other is the household dredger , such as "one-bomb dredge", "skin bowl dredge" or "spring manual mechanical dredge", etc., are easy to use, but the effect is not very satisfactory

[0004] To be specific: "One Cannon Dredge" adopts air pressure to dredge. In order to prevent backflow and seal water, the sewer pipe generally adopts the structure of water storage bay, and the diameter of the pipe is different. "One Cannon Dredge" is used in specific When the blocking point is close to the water inlet, the effect can only be good. When the blocking point is far away from the water inlet, the blocking and dredging effect is poor or cannot be blocked and dredged.

The "skin bowl dredge" can only be effective when the blocking point is close to the water inlet. When the blocking point is far away from the water inlet, the effect of unblocking and unblocking is poor or cannot be unblocked.

The "spring manual mechanical dredger" is easy to damage the pipe wall during use, and it is easy to cause leakage of the sewer pipe after repeated use. Once the floor leaks, you have to renovate your own floor and compensate the neighbors downstairs. The gain outweighs the loss, and the cost of dredging is high.
