Problems solved by technology

[0002] In the prior art, the air stagnation in the inner cavity of the tunnel body will seriously affect the air quality, which is unfavorable to the health of passers-by. less gas exchange between the air and the atmosphere outside the tunnel body, resulting in poorer air quality in the inner cavity of the tunnel body
[0003] In order to solve the above problems, various ventilation devices have been proposed in the prior art. However, most of the existing ventilation devices rely on external electric power to drive fans to ventilate the tunnel body. The cost of traffic operation is poor, and the economy is poor; there are also some ventilation devices without external drive, and their ventilation capacity is very weak, which cannot meet the ventilation requirements of the tunnel body

Embodiment 1

[0042] see image 3 The tunnel provided in this embodiment includes a tunnel body 6 and the aforementioned non-powered ventilation device, the ventilation duct 1 is arranged along the extension direction of the tunnel body 6, the blower assembly 2 is located outside the tunnel body 6, and the second tuyere 102 is located in the tunnel body 6 , the unpowered wind balloon 202 is located in the tunnel body 6 , and the rotation axis of the unpowered wind balloon 202 is perpendicular to the extending direction of the tunnel body 6 .

[0043] Because the tunnel body 6 is generally a long and narrow space, the closer to the exit of the tunnel body 6 in the long and narrow space of the tunnel body 6, the more the gas exchanges with the gas outside the tunnel body 6, and the farther away from the position of the exit of the tunnel body 6, the more The less the gas exchanges with the gas outside the tunnel body 6; the worse the gas quality is at the position farther away from the outlet...

Embodiment 2

[0049] see image 3 The tunnel provided by this embodiment includes a tunnel body 6 and the aforementioned unpowered ventilation device, each ventilation duct 1 is arranged along the extension direction of the tunnel body 6, and each ventilation duct 1 communicates with the inner cavity of the tunnel body 6 main body and the tunnel body 6 The external environment of the main body; each unpowered wind ball 202 is located in the tunnel body 6, and the rotation axis of each unpowered wind ball 202 is perpendicular to the extension direction of the tunnel body 6; Fan the wind in the direction of the tunnel body 6; in another part of the non-powered ventilation device, the rotating fan 201 fans the wind from the inside of the tunnel body 6 to the direction outside the tunnel body 6. Due to the use of the aforementioned unpowered ventilation device, under the action of the unpowered wind ball 202, the blower assembly 2 can transfer the kinetic energy of the airflow blowing on it alo...

Abstract

The invention relates to the technical field of mine or tunnel ventilation, and provides an unpowered ventilation device and a tunnel. The unpowered ventilation device comprises a ventilation pipelineand an air blowing assembly, and a first air opening and a second air opening are formed in the ventilation pipeline; the air blowing assembly comprises a rotating fan and an unpowered wind ball, theunpowered wind ball comprises a rotating impeller, a rotating fan is installed in an inner cavity of the ventilation pipeline, the fan direction of the rotating fan extends towards the ventilation pipeline, the unpowered wind ball is installed outside the ventilation pipeline, the rotating impeller is installed in an air flue of the unpowered wind ball, and the rotating fan is in transmission connection with the rotating impeller; the rotating shell of the unpowered wind ball can converts airflow blown in each direction into vortex airflow in the same direction inside the unpowered wind ball,then, the rotating fan is driven to flap gas inside the ventilation pipeline to continue to flow in the same direction on the condition that no man applies power, and the ventilation efficiency of the ventilation pipeline is enhanced.

Description

technical field [0001] The invention relates to the technical field of ventilation in mines or tunnels, in particular to a non-powered ventilation device and a tunnel. Background technique [0002] In the prior art, the air stagnation in the inner cavity of the tunnel body will seriously affect the air quality, which is unfavorable to the health of passers-by. The less gas exchange there is between the air and the atmosphere outside the tunnel body, resulting in poorer air quality in the inner cavity of the tunnel body. [0003] In order to solve the above problems, various ventilation devices have been proposed in the prior art. However, most of the existing ventilation devices rely on external electric power to drive fans to ventilate the tunnel body. The cost of transportation operation is poor, and the economy is poor; there are also some ventilation devices without external drive, and their ventilation capacity is very weak, which cannot meet the ventilation requiremen...
