Problems solved by technology

At present, the general situation of tunnel ventilation in my country is that medium and long tunnels use jet ventilation, and long tunnels use shafts with jet ventilation. Although the ventilation effect is good, the annual power consumption is very large, because the fans in the tunnel need to It runs all day long, and the wind energy generated by the tunnel fan is not fully utilized. Therefore, there is no optimal energy-saving ventilation method. How to improve the current ventilation system and reduce energy consumption and operating costs is an economically significant issue at present.

Embodiment 1

[0035] The length of a highway tunnel is 1km, the design driving speed is 80km / h, and the ventilation method is designed as jet mechanical ventilation. see Figure 1 to Figure 4 , an example is given.

[0036] Step 1: Calculate the number of generating units according to the length of the tunnel and the installation distance, and prepare the required 200 sets of road vibration generating units in advance. Conductors lead out for standby, forming a road power generation system 5;

[0037] Step 2: After the tunnel construction is completed, install the jet fan 2. The required number and installation distance of the jet fan 2 are determined according to the length of the tunnel and the traffic flow. ready to use;

[0038] Step: 3: Determine the quantity of required wind generators 3 according to the length of the tunnel 1 and the number of jet fans, install the wind generators 3 symmetrically at the left and right side walls of the tunnel 1, and arrange the leads for standby; ...

Embodiment 2

[0044] The length of a highway tunnel is 6km, and the design driving speed is 80km / h. The ventilation method is a vertical shaft equipped with jet-type longitudinal ventilation, and a vertical shaft is set in the middle of the tunnel. see figure 1 , figure 2 and Figure 5 , giving another example.

[0045] Step 1: Calculate the number of generating units according to the length of the tunnel and the installation distance, and prepare the required 1200 sets of road vibration generating units in advance. Conductors lead out for standby, forming a road power generation system 5;

[0046] Step 2: After the tunnel construction is completed, install the jet fans 2. The required number and installation spacing of the jet fans 2 are determined according to the length of the tunnel, the traffic volume and the height of the shaft. The jet fans 2 are installed in groups of two on the tunnel vault and the shaft. , the power line and control line are ready for use;

Abstract

The invention discloses a tunnel energy-saving ventilation linkage comprehensive control system and a mounting method thereof. The tunnel energy-saving ventilation linkage comprehensive control systemcomprises a power supply system and a camera arranged at an inlet of a tunnel, a plurality of CO detectors and a plurality of dust detectors are arranged in the tunnel, and a plurality of jet flow draught fans are arranged at the top in the tunnel. The camera, the CO detectors and the dust detectors are connected with a control system, the control system is connected with the jet flow draught fans, and the power supply system is connected with the jet flow draught fans, the camera, the CO detectors, the dust detectors and the control system. According to the tunnel energy-saving ventilation linkage comprehensive control system and the mounting method thereof, through the camera, the CO detectors and the dust detectors, the vehicle flow, CO and dust are monitored in real time, data are fedback to the control system in real time, the operation condition of the jet flow draught fans is controlled in real time by the control system according to the collected monitoring information, and intelligent energy-saving control of the system is achieved; and all modules are clear in function, environmentally friendly and capable of saving energy, the operation cost of the tunnel in the laterperiod can be effectively lowered, and good application value is achieved.

Description

technical field [0001] The invention belongs to the field of traffic operation energy saving, and in particular relates to a tunnel energy saving ventilation linkage integrated control system and an installation method. Background technique [0002] my country's highways have basically been built into a network, and a large number of road tunnels have been built at present. According to statistics, the number of road tunnels currently in operation has reached thousands. With the improvement of construction technology, the length of a single tunnel has become longer and longer. For example, the Qinling Zhongnanshan Highway Tunnel in Shaanxi is 18.02 kilometers long. The road tunnel operation specification stipulates that the mechanical ventilation method is comprehensively determined according to the road grade, tunnel length, tunnel section size, traffic flow, etc. Generally, the tunnel length exceeds a certain value and starts to be equipped with mechanical ventilation. At ...
