Description

Pipe leakage prevention device

The present invention relates to an anti-leakage device, and more particularly to an anti-leakage device for a pipe body for airflow exchange.

The conventional airflow exchange device can be installed on a wall of a building, and the airflow exchange device comprises a pipe body, a partition plate, a waterproof ring and two fans. The two ends of the tube are respectively located in an outdoor space and an indoor space on the two sides of the outer wall, and the partition is disposed inside the tube to divide the first guiding space and the second guiding space. The waterproof ring is sleeved on the outer peripheral wall of the tube and adjacent to the outdoor space, the waterproof ring is for preventing moisture from penetrating into the inner space, and the two fans are respectively coupled to the first guiding space and the second guiding space. Thereby, the airflow switching device can use the fan of the first air guiding space to introduce the airflow of the outdoor space into the indoor space, and use the fan of the second guiding space to export the airflow of the indoor space to the outdoor space to provide Circulating ventilation and ventilation function. An embodiment similar to the conventional airflow switching device has been disclosed in the Patent Office of the Republic of China Announcement No. I571604 "Airflow Exchange Device and Its Barrier".

However, in order to achieve a good waterproof effect, the outer diameter of the waterproof ring is mostly larger than the outer diameter of the pipe body, and the outer diameter of the pipe body is smaller than the diameter of the mounting hole of one of the outer walls, and therefore, the outdoor space must be The airflow exchange device is installed on one side of the space, but if the building does not have a balcony for construction work, the construction personnel must cooperate with a large suspension device and stand in a cage for high-altitude operation, making construction difficult. Degree and risk increase.

In view of this, the conventional airflow exchange device does have a need for improvement.

In order to solve the above problems, the present invention provides an anti-leakage device for a pipe body which can be installed from one side of an indoor space to improve work efficiency and increase construction safety.
