Problems solved by technology

[0003] During the construction of the tunnel, in order to ensure the safety of the construction personnel, it is necessary to perform ventilation operations in the tunnel, and a large amount of smoke and dust will be generated during the construction of the tunnel, which will cause harm to the personnel in the tunnel and interfere with the line of sight. , and because a large amount of dust is produced to reduce the moisture content in the air, the comfort level will be reduced in this environment for a long time. The kinetic energy of the wind will gradually decrease due to the increase of the ventilation distance. Therefore, when the tunnel is too long, the existing ventilation device often cannot pass the wind to the depth of the tunnel, which reduces the ventilation efficiency.

Embodiment 1

[0029] see figure 2 , an internal and external ventilation device when excavating a tunnel, including a fan 1, the interior of the fan 1 contains a ventilation mechanism 2, the interior of the ventilation mechanism 2 is provided with a driving gear 21, and the external meshing connection of the driving gear 21 is connected with a driven gear The gear 22, the driven gear 22 is provided with a drive shaft 23 inside, the outside of the drive shaft 23 is movably connected with a ventilation fan 24, the outside of the ventilation fan 24 is sleeved with a ventilation cavity 25, and the outside of the ventilation cavity 25 is movably connected with a thin Flow tube 26 .

[0030] The motor drives the driving gear 21 to rotate, so that it drives the driven gear 22 meshing with it to start to rotate, so the transmission shaft 23 drives the ventilation fan 24 to start to rotate, and a ventilation cavity 25 is sleeved outside the ventilation fan 24. , and a thin flow tube 26 is connecte...

Embodiment 2

[0032] see Image 6 , an internal and external ventilation device during excavation of a tunnel, comprising a ventilator 1, the interior of the ventilator 1 also includes a vibrating screen drop mechanism 3, the inside of the vibrating screen drop mechanism 3 is provided with a knocking rod 31, and the outside of the knocking rod 31 is A positioning clip 32 is sleeved, a vibration plate 33 is arranged at the lower end of the knock bar 31 , a sliding rod 34 is arranged at the lower end of the vibration plate 33 , and a windshield blade 35 is movably connected to the lower end of the vibration plate 33 .

[0033] When used for a long time, the dust will block the inside of the filter cotton, so that the air cannot pass through it, and the air overflows and flows to both sides, so that the air drives the windshield blade 35 to move the vibrating screen drop mechanism 3 to the right, so that the The inner vibrating plate 33 is in contact with the abutting rod 45, so that the abutt...

Embodiment 3

[0035] see Figure 4, an internal and external ventilation device when excavating a tunnel, including a fan 1, the interior of the fan 1 also includes a static electricity generating mechanism 4, the interior of the static electricity generating mechanism 4 is provided with a first filter cotton 41, and the positive side of the first filter cotton 41 is A second filter cotton 42 is arranged below, a support plate 43 is movably connected to the outside of the second filter cotton 42, an abutment block 44 is movably connected to the outside of the support plate 43, and an abutment rod 45 is arranged outside the abutment block 44 to abut A turntable 46 is movably connected to the outside of the post 45 .

[0036] After the air enters the suction pipe 5 through the ventilation cavity 25 and the thin flow pipe 26, it enters the interior of the processing cavity 7 from the air inlet 6, and the turntable 46 is driven to rotate by the motor, so that the abutment rod 45 outside the tur...

Abstract

The present invention relates to the technical field of tunnel ventilation, and discloses an internal and external ventilation device for tunnel excavation, including a ventilator. The ventilator includes a ventilating mechanism inside, and a driving gear is arranged inside the ventilating mechanism. The outside of the transmission shaft is movably connected with a ventilation fan, and the outside of the ventilation fan is sleeved with a ventilation cavity, and the outside of the ventilation cavity is movably connected with a fine flow tube, and the inside of the ventilation fan also includes a vibrating screen The falling mechanism of the vibrating sieve is equipped with a knocking rod inside, the outside of the knocking rod is sleeved with a positioning clamp, the lower end of the knocking rod is provided with a vibrating plate, and the lower end of the vibrating plate is set There is a slide bar, and the lower end of the vibrating plate is movably connected with windshield vanes. The device has the advantages of simultaneously inhaling and exchanging air, reducing the use of ventilation ducts, reducing material costs, accelerating and humidifying the air, increasing the transmission distance and increasing comfort.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation, in particular to an internal and external ventilation device during tunnel excavation. Background technique [0002] Tunnels are buildings built underground or underwater or in mountains, laying railways or building roads for motor vehicles to pass through. In order to shorten the distance and avoid large slopes, they are called mountain tunnels to cross under mountains or hills; for crossing rivers Underwater tunnels are called underwater tunnels that pass under the river or under the sea through straits or straits; urban tunnels are called urban tunnels that pass under the city in order to meet the needs of railways passing through big cities. [0003] During the construction of the tunnel, in order to ensure the safety of the construction workers, it is necessary to carry out ventilation and ventilation operations in the tunnel. During the construction of the tunnel, a large amount ...
