Through-Type Drain Pump Pipe Insertion Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During maintenance work on fluid pipes, such as replacing old pipes or connecting branch pipes, the remaining chemically-treated hot water inside the pipes is not effectively drained, leading to environmental pollution when leaks occur, as existing technologies fail to efficiently manage fluid discharge during these processes.
Innovation Solution
A through-type drain pump with a hollow cylindrical housing, a rotary shaft driven by a motor, an impeller for fluid movement, and a mounter for easy insertion and lifting, allowing for efficient drainage of fluids from pipes during maintenance, enabling unskilled personnel to perform the task effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pump is used for draining fluid during pipe maintenance, then the pump can remove fluid from the pipe, but the installation and separation process becomes complex and time-consuming
Solution Approach 1:
The pump body is divided into separable sections with connection portions that can be easily connected and disconnected. The housing includes a first housing and a second housing that can be separated, allowing the pump to be installed and removed in segments rather than as a single complex unit.
Solution Approach 2:
The connection portion is designed with a universal structure that can connect to different pipe types and configurations. The connection portion includes a connection body that can interface with various pipe openings, making the same pump design applicable to multiple maintenance scenarios without requiring complex custom installations.
2Productivity
If maintenance work is performed on pipes with fluid inside, then the pipe can be repaired without replacement, but the remaining fluid causes environmental pollution when leaked
Solution Approach 1:
The pump is installed in the pipe before maintenance work begins, and fluid drainage is initiated immediately. The connection portion is pre-configured to seal against the pipe interior surface, creating an effective drainage system before any maintenance activities that might cause leakage occur.
Solution Approach 2:
The connection portion utilizes the internal pressure and flow of the fluid itself to assist in sealing and securing the pump in place. The fluid flow that would otherwise be a hazard is converted into a force that helps maintain the seal and keeps the pump positioned during operation.
3Reliability
If a complex mounting system is used to secure the pump to the pipe, then the pump remains stable during operation, but the installation and separation process becomes difficult for unskilled personnel
Solution Approach 1:
The connection portion is designed to be self-aligning and self-sealing. When the pump is inserted into the pipe, the connection body automatically positions itself and creates a seal without requiring precise alignment or complex fastening procedures by the installer.
Solution Approach 2:
The connection system includes flexible sealing elements and movable connection components that adapt to variations in pipe dimensions and conditions. The seal portion can deform or adjust its position to maintain a reliable seal even when there are minor variations in pipe geometry or installation alignment.

Function Achieved in This Case
The through-type drain pump facilitates easy installation, insertion, and separation, ensuring that fluids are efficiently drained from pipes, reducing the risk of environmental pollution and making maintenance work more accessible and safer by preventing fluid leaks during pipe repairs and replacements.
Implementation Method 1
an impeller formed at a lower end of the rotary shaft, the impeller being configured to move the fluid introduced through the fluid inlet port to the fluid outlet port through the fluid movement path when the impeller is rotated

AI summary
Proposed is a through type drain pump for a fluid draining apparatus of a fluid pipe. The drain pump includes: a housing formed in a hollow cylindrical shape, the housing being configured such that a fluid inlet port and a fluid outlet port are in communication with each other via a fluid movement path; a rotary shaft having a driving motor, the rotary shaft being rotatably coupled to an output shaft of the driving motor via a coupler; an impeller formed at a lower end of the rotary shaft and configured to be rotated so that the fluid is moved to the fluid outlet port through the fluid movement path; and a mounter mounted at a lower outer side surface of the housing and configured to mount the drain pump on any pipe such that the drain pump is capable of being lifted and inserted into the pipe.
