Embodiment Construction
[0023] In order to easily understand the technical means, creative features, goals and effects of the present invention, the present invention will be further described below in conjunction with specific illustrations.
[0024] Such as Figure 1-Figure 3 As shown, a jet fan for a spiral tunnel includes a jet fan and a curved sound-absorbing guide tube;
[0025] The jet fan is composed of a fan cylinder 1, a motor 2, a motor bracket 3, and fan blades 4. The motor 2 and the fan cylinder 1 are arranged on the same axis. The motor 2 is fixed in the fan cylinder 1 through the motor bracket 3. The shaft of the motor 2 Fan blade 4 is fixed on it;
[0026] The curved noise-absorbing guide cylinder is composed of a curved curved cylinder body 5, a direction adjustment screw 6, and a sound-absorbing material 7. The two ends of the fan cylinder body 1 are respectively provided with a connecting ring 11 tightly inserted into one end of the curved cylinder body 5. The ring 11 is equidist...

The invention discloses a jet fan for a spiral tunnel, and belongs to the field of tunnel ventilation equipment. The jet fan comprises a jet fan body and curvilinear silencing and flow guiding cylinders, wherein the jet fan body is composed of a fan cylinder body, a motor, a motor support and fan blades, the motor is arranged coaxial with the fan cylinder body, the motor is fixed in the fan cylinder body through the motor support, the fan blades are fixed on a rotating shaft of the motor, and each curvilinear silencing and flow guiding cylinder is composed of a curved curvilinear cylinder body, direction adjusting screws and a sound absorbing material. The curvilinear silencing and flow guiding cylinders are installed at the two ends of the jet fan body so that the noise can be greatly reduced, the equipment is kept to run quietly, moreover, the curved curvilinear cylinder bodies can keep the air inlet and outlet direction of the jet fan body consistent with the driving direction of the spiral tunnel, the curvilinear silencing and flow guiding cylinders combine silencing structures and curve flow guiding structures, so that the weight and the volume are reduced.
Description
technical field [0001] The invention relates to a jet fan for a spiral tunnel, belonging to the technical field of tunnel ventilation equipment. Background technique [0002] The spiral tunnel realizes the function of driving in the mountain through the construction of a spiral ascending or descending driving tunnel in the mountain. The spiral tunnel structure includes a curved structure and a structure with a vertical slope change up and down. The line spirals continuously in a clockwise or counterclockwise direction, and the length is exchanged for height. The spiral tunnel is an ideal solution to reduce the slope of tunnel driving, avoid tunnel faults, reduce the drop between tunnel entrance and tunnel exit, and ensure the safety of climbing routes. [0003] The main structure of the spiral tunnel is a curve. Vehicles always drive along the tunnel curve in the tunnel, and the road surface always has a slope change. For the uphill tunnel, the exhaust emission of the car i...
