Description

Technical Field

[0001] The utility model relates to the technical field related to tunnel ventilation and cooling, in particular to tunnel ventilation and cooling equipment. Background Art

[0002] The structure of the existing commonly used tunnel ventilator is composed of a ventilator and a ventilation hose. The ventilator is arranged outside the tunnel, and the ventilation hose is connected to the end of the ventilator and extends to the air supply position. As the excavation depth increases, the ventilator is farther away from the excavation surface. Under the condition of high ground temperature, construction workers generally feel that the wind blown into the tunnel by the ventilator is too hot. The air temperature in the tunnel operation range is high. Working for a long time in such a harsh working environment is very detrimental to the health of the workers, and is not conducive to the strength of the lining concrete and the development of cracks.

[0003] The utility model patent with announcement number CN218882277U discloses a tunnel ventilation and cooling equipment, which belongs to the technical field related to tunnel ventilation and cooling, and aims to solve the problem that the current ventilation and cooling equipment in the prior art basically has no ability to adjust the height and has great application limitations in construction and excavation. The utility model patent includes: an equipment box, an axial flow fan, the axial flow fan can be installed above the equipment box in a liftable manner, a refrigerator is provided on one side of the equipment box, the pipe mouth of the air inlet pipe of the refrigerator is located at the lower part of the equipment box, an air outlet pipe is provided on the upper part of the refrigerator, and the air outlet pipe is connected to the front part of the axial flow fan; an atomizer is provided on the other side of the equipment box, a water tank is provided below the atomizer, a water pump is provided between the atomizer and the water tank, the water pump sends water in the water tank into the atomizer, a mist outlet pipe is provided above the atomizer, and the mist outlet pipe is connected to the rear part of the axial flow fan. The ventilation and cooling equipment is equipped with a refrigeration device and an atomizer. The axial flow fan supplies air to the inside of the tunnel. The refrigeration device can provide cold air to cool the tunnel. The atomizer can cool and reduce dust. In addition, the cold air and water mist will first be input into the axial flow fan, and then diffused by the axial flow fan, so that its effective area is larger.

[0004] However, the above patent still has shortcomings: the patent cools down and reduces dust inside the tunnel by setting an atomizer, but since the interior of the tunnel is in a dark and humid state for a long time, the air inside the tunnel is humidified by the atomizer, which causes the air humidity inside the tunnel to increase significantly.

At the same time, the power mechanism 6 controls the first rotating shaft 4 to rotate. The first rotating shaft 4 rotates while driving the heat dissipation blades 5. The heat dissipation blades 5 rotate to blow out the cooled air inside the device, thereby achieving the purpose of cooling the inside of the tunnel. The device achieves the purpose of improving the cooling effect of the device by cooling the air entering the device and increasing the air flow rate. This solves the problem that the air inside the tunnel is humidified by the atomizer, which causes the air humidity inside the tunnel to increase significantly. The workers are prone to diseases when working in a humid environment for a long time.

[0027] like Figure 2 and Figure 3As shown, the power mechanism 6 includes: one end of the first rotating shaft 4 away from the heat dissipation blade 5 is fixedly connected to the first bevel gear 9, the side of the first bevel gear 9 away from the first rotating shaft 4 is meshed with the second bevel gear 10, and the center of the second bevel gear 10 is fixedly connected to the second rotating shaft 11; the top end of the second rotating shaft 11 passes through the cooling box 1 and extends to the motor 12, the motor 12 is fixedly connected to the cooling box 1, and the second rotating shaft 11 is fixedly connected to the output end of the motor 12; a linkage mechanism 13 for controlling the synchronous rotation of the two first rotating shafts 4 is arranged between the first bevel gear 9 and the circular plate 3, the motor 12 is started, the output end of the motor 12 drives the second rotating shaft 11, the second rotating shaft 11 drives the second bevel gear 10, the second bevel gear 10 drives the first bevel gear 9, the first bevel gear 9 drives the first rotating shaft 4, the first rotating shaft 4 is synchronously rotated through the cooperation of the linkage mechanism 13, and the first rotating shaft 4 drives the heat dissipation blades 5 to rotate rapidly while rotating.
