Description
技术领域 technical field
本实用新型属于隧道通风技术领域，特别涉及一种公路用隧道通风结构。 The utility model belongs to the technical field of tunnel ventilation, in particular to a tunnel ventilation structure for highways.
背景技术 Background technique
交通隧道内良好的空气状态是行车安全的必要条件，通风是为了把隧道内的有害气体或污染物质的浓度降低，保证汽车行驶的安全性和舒适性。 A good air condition in the traffic tunnel is a necessary condition for driving safety. Ventilation is to reduce the concentration of harmful gases or pollutants in the tunnel and ensure the safety and comfort of driving.
现有隧道常见的通风方式有以下几种： Common ventilation methods for existing tunnels are as follows:
自然通风：所谓自然通风是指通过隧道内经过的汽车的活塞作用与自然风的作用，将有害气体和烟尘从隧道内排除。采用自然通风模式受限于隧道内车流量的大小，并且自然风的不稳定性和复杂性会大大影响隧道内的气流交换。 Natural ventilation: The so-called natural ventilation refers to the removal of harmful gases and smoke from the tunnel through the piston action of cars passing through the tunnel and the natural wind. The use of natural ventilation mode is limited by the traffic flow in the tunnel, and the instability and complexity of natural wind will greatly affect the airflow exchange in the tunnel.
纵向式通风：所谓纵向式通风是从一个洞口引进新鲜空气，通过另一个洞口排除污染空气的方式。这种方式，空气污染程度由入口向出口方向呈线性增加，入口处污染浓度最小，出口内测污染浓度大。遇火灾情形会导致出口洞口处浓度高，排烟不便。现有纵向式通风采用的送风机功率比较大，造价比较高且噪音污染严重，不够经济环保。 Longitudinal ventilation: The so-called longitudinal ventilation is a way to introduce fresh air from one opening and remove polluted air through another opening. In this way, the degree of air pollution increases linearly from the inlet to the outlet, the pollution concentration at the inlet is the smallest, and the pollution concentration in the outlet is the largest. In case of fire, the concentration at the exit hole will be high and the smoke exhaust will be inconvenient. The power blower used in the existing longitudinal ventilation is relatively large, the cost is relatively high, and the noise pollution is serious, which is not economical and environmentally friendly.
现有技术中的通风装置不能根据天气及其他特殊情况而随时改变每个通风装置的开启和关闭，会容易造成资源浪费和通风效率低的问题。 The ventilation devices in the prior art cannot change the opening and closing of each ventilation device at any time according to the weather and other special conditions, which will easily cause the problems of waste of resources and low ventilation efficiency.

There are several exhaust devices 3, and the exhaust device 3 is connected with the air outlet channel 2 through the connecting pipe 16, the connecting pipe 16 is provided with a smoke detector 9, the connecting pipe 16 is provided with a cover body 12, and the bottom of the cover body 12 is provided with The bottom plate 13 is provided with several ventilation holes 15, the cover body 12 is provided with an exhaust fan 10; the ground 4 is provided with a drainage groove 6, and several drainage outlets 5 are arranged on the drainage groove 6. The inner wall of the tunnel 1 A water level alarm 7 is provided at a position half a meter away from the ground.
进一步的，所述出风通道2末端设置有通风控制器8。 Further, a ventilation controller 8 is provided at the end of the air outlet channel 2 .
进一步的，所述底板13一端设置有限制底板向下运动的锁紧装置14。 Further, one end of the bottom plate 13 is provided with a locking device 14 that restricts the bottom plate from moving downward.
进一步的，所述排气风机10上设置有数个叶片11。 Further, the exhaust fan 10 is provided with several blades 11 .
进一步的，所述出风通道2上设置有不少于五个排风装置3。 Further, no less than five exhaust devices 3 are arranged on the air outlet channel 2 .

进一步的，所述出风通道2截面为正方形。 Further, the section of the air outlet channel 2 is square.
平时出风通道2上只开一致两个排风装置3，当烟感探测器9检测到大量烟雾时，开启通风控制器8，将其余所有排风装置3都开启，同时打开锁紧装置使得底板13脱离罩体12让大量烟雾能够直接通过出风通道2排出，增大了排烟效率。当设置不少于五个排风装置3时排烟效率最高。同时出风通道2截面为方形时也有利于排烟，正方形时排烟效率最高。地面4上设置排水槽6方便积水排出，同时隧道内壁1上设置水位报警器7，当水到达水位报警器7时，水位报警器7接触到水会发生警报，及时通知相关部门进行救援和疏通车辆，避免造成不必要的损失和人员伤亡。 Usually, only two exhaust devices 3 are opened on the air outlet channel 2.
