Abstract

The invention relates to a tunnel cooling vehicle which is convenient for intelligent adjustment of the jet flow direction, which comprises a vehicle jet fan, a cooling grid, a liquid outlet pipe, a liquid return pipe, a circulating pump, a heat exchanger and a closed refrigerator; the front end of the jet fan is fixed with a The infrared temperature detector used to detect the temperature distribution in front of the cooling vehicle, the control device receives the temperature detection data of the infrared temperature detector, the control device controls the hydraulic cylinder to adjust the jet flow direction of the jet fan, and the control device controls the The drive motor is used to adjust the left and right jet direction of the jet fan; the circulation pump drives the heat exchange fluid to continuously circulate in one direction along the heat exchanger, circulation pump, cooling grid, liquid return pipe and heat exchanger. The configuration of the supporting structure of the jet fan enables the jet fan to be operated conveniently, and the jet direction in the left and right directions can be adjusted to a large extent in the control range, so that it can perform targeted jet cooling operation on the inside of the tunnel, so that the local cooling efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of tunnel cooling equipment, in particular to a tunnel cooling and ventilation device with low humidity air supply. Background technique [0002] During the construction of railways and expressways, tunnel construction projects are often encountered. In the construction of tunnels, high rock temperature is often encountered, which leads to high construction environment temperature (Sangzhuling Tunnel of Sichuan-Tibet Railway, which has the highest rock temperature currently encountered. The rock temperature is 81.9 ℃). When the construction temperature is higher than the temperature inside the tunnel 28 ℃ stipulated in the "Code for Construction of Railway Tunnels" TB10120-2002, the high ground temperature and heat disaster in the tunnel will reduce the labor capacity of construction workers, have a great impact on health, greatly increase the incidence of altitude sickness, and cause mechanical equipment failure. Th...
