Problems solved by technology
[0003] In order to have a good operating environment inside the pipe gallery, it is necessary to set up a ventilation shaft connected to the outside of the pipe gallery to ventilate the air inside the pipe gallery. However, because the pipe gallery is usually deep, it is difficult for the air far away from the ventilation shaft to communicate with the outside world. Exchange, which makes the ventilation inside the pipe gallery more difficult

The present invention belongs to the technical field of comprehensive pipe gallery, especially a kind of ventilation system of urban underground comprehensive pipe gallery. In view of the problems existing in the prior art, the following scheme is proposed, including the pipe gallery arranged on the ground, and the upper part of the pipe gallery is set There are intermittently distributed air inlet modules and air outlet modules. The air inlet module includes a vertical cylinder fixedly installed on the ground, and the top outer wall of the vertical cylinder is rotatably connected with a rotating drum, and the side outer wall of the rotating drum is fixedly connected with a circular uniform distribution The top of the side outer wall of the drum is rotatably connected with a top shell. The invention divides the entire pipe gallery into several ventilation needs, and then can fully ventilate the pipe gallery; at the same time, it is ventilated through the driving of external vehicles and the power generated by the external wind force, which saves energy and reduces the air entering the pipe gallery. Temperature, so as to prevent the temperature in the pipe gallery from being too high, prevent dust accumulation on the filter, and keep the ventilation of the filter smooth.
Description
technical field [0001] The invention relates to the technical field of comprehensive pipe gallery, in particular to a ventilation system for urban underground comprehensive pipe gallery. Background technique [0002] The urban underground comprehensive pipeline gallery is an underground urban pipeline comprehensive corridor, that is, a tunnel space is built underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting The port and monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city, which is usually located between the ground and underground rails. [0003] In order to have a good operating environment inside the pipe gallery, it is necessary to set up a ventilation shaft connected to the outside of the pipe gallery to v...
