Abstract

The invention relates to a tunnel cooling vehicle facilitating intelligent regulation of a jet direction. The tunnel cooling vehicle facilitating the intelligent regulation of the jet direction comprises a carrying vehicle, a jet fan, a cooling grid, a liquid outlet pipe, a liquid return pipe, a circulating pump, a heat exchanger and a closed refrigerator; an infrared temperature detector which isused for detecting the temperature distribution in front of a cooling vehicle is fixedly arranged at the front end of the jet fan; a control device receives temperature detection data of the infraredtemperature detector; the control device controls a hydraulic oil cylinder to regulate the up-down jet direction of the jet fan; the control device controls a driving motor to regulate the left-rightjet direction of the jet fan; and the circulating pump drives a heat exchange liquid to perform continuous one-way circular flow along the heat exchanger, the circulating pump, the cooling grid, theliquid return pipe and the heat exchanger. Through the configuration of a supporting structure of the jet fan, the jet fan can be convenient to operate and can adjust the jet direction in left-right direction in within a large range, so that the jet fan can perform a targeted jet cooling operation on the interior of a tunnel; and therefore, 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 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 (the Sangzhuling Tunnel of Sichuan-Tibet Railway with the highest rock temperature currently encountered The rock temperature is 81.9°C). When the construction temperature is higher than the temperature in the tunnel of 28°C stipulated in the "Railway Tunnel Construction Code" TB10120-2002, the high ground temperature and heat disaster in the tunnel will reduce the labor capacity of the construction workers, have a great impact on health, and the incidence of altitude sickness will increase significantly, and mechanical equipment will fail. The...
