Description

一种隧道通风机健康度评估方法及其系统A method and system for evaluating the health of tunnel ventilators

技术领域technical field

本发明涉及隧道通风机技术领域,尤其涉及一种隧道通风机健康度评估方法及其系统。The invention relates to the technical field of tunnel ventilators, in particular to a method and system for evaluating the health of tunnel ventilators.

背景技术Background technique

隧道作为山体的快捷穿过方式,已成为城市公路的主要组成部分。随着国民经济的快速发展,我国地下隧道建设数量以及隧道长度的不断增加。这些隧道在解决通行的同时,也存在很多隐患:汽车在行驶过程中,往往需要消耗大量的氧气,同时排放大量的废气,如CO2、CO、氮氧化合物等,而隧道作为相对密封的空间,如果无法即时将这些气体排出,将对人体产生不良的影响;不仅如此,车辆排放的废气中往往含有一些固体颗粒,当隧道内的固体颗粒的浓度较高时,将导致能见度降低,进而影响驾驶员的行车安全性;同时隧道作为相对密封的空间,仅依赖自然风进行氧气的补充、废气的处理往往达不到预期效果;另外隧道的特点是空间狭长,一旦在隧道内发生火灾,产生的大量烟气威胁人员逃生、影响火灾扑救路线、阻碍救援人员到达和对伤员的救助。因此,在隧道中设计风机来辅助隧道通风显得十分重要。通风系统主要是完成隧道内部通风换气,实现隧道内部空气质管控和温度管控,确保交通运行安全。所以,对通风风机的安全性提出了很高的要求,必须保证风机的工作状态。As a quick way to pass through mountains, tunnels have become a major part of urban highways. With the rapid development of the national economy, the number of underground tunnels in my country and the length of the tunnels are increasing. While these tunnels solve traffic problems, there are also many hidden dangers: cars often need to consume a lot of oxygen and emit a lot of waste gas, such as CO 2 , CO, nitrogen oxides, etc., during driving, and tunnels are relatively sealed spaces. , if these gases cannot be discharged immediately, it will have adverse effects on the human body; not only that, the exhaust gas emitted by vehicles often contains some solid particles, when the concentration of solid particles in the tunnel is high, it will lead to reduced visibility, which will affect Driving safety of the driver; at the same time, as a relatively sealed space, the tunnel only relies on natural wind for oxygen supplementation and exhaust gas treatment often fails to achieve the expected results; in addition, the tunnel is characterized by a long and narrow space. Once a fire occurs in the tunnel, the A large amount of smoke threatens the escape of personnel, affects the fire fighting route, and hinders the arrival of rescuers and the rescue of the wounded. Therefore, it is very important to design fans in the tunnel to assist tunnel ventilation. The ventilation system is mainly to complete the ventilation inside the tunnel, realize the air quality control and temperature control inside the tunnel, and ensure the safety of traffic operation. Therefore, high requirements are put forward for the safety of the ventilation fan, and the working condition of the fan must be guaranteed.

现有技术方案中,关于隧道安全通风集中于以下方面:In the prior art scheme, the safety ventilation of the tunnel focuses on the following aspects:

1)隧道内部安装有安全监测系统来检测隧道内部的整体情况来保证隧道的运行安全。1) A safety monitoring system is installed inside the tunnel to detect the overall situation inside the tunnel to ensure the safe operation of the tunnel.

例如申请号为CN202210033733.X专利提出的一种智慧城市隧道安全监测系统;申请号为202011369455.2专利提出的一种可视化地铁隧道安全综合监测及智能应急系统。For example, a smart city tunnel safety monitoring system proposed by patent application number CN202210033733.X; a visualized subway tunnel safety comprehensive monitoring and intelligent emergency system proposed by patent application number 202011369455.2.

2)安全节能通风系统的控制。2) Control of safe and energy-saving ventilation system.

例如申请号为CN202010196482.8专利提出的一种高速公路隧道安全节能通风系统的控制方法,对风机进行调解控制。申请号为CN202210717741.6专利提出的一种隧道火灾灭火系统和排烟系统的控制方法,涉及一种隧道灭火和排烟的控制系统。申请号为CN202110747356.1提出的一种安全疏散通道的加压送风系统。For example, the patent application number CN202010196482.8 proposes a control method for a safe and energy-saving ventilation system in expressway tunnels, which mediates and controls the fans. The application number is CN202210717741.6, which proposes a control method for a tunnel fire extinguishing system and a smoke exhaust system, and relates to a tunnel fire extinguishing and smoke exhaust control system. The application number is CN202110747356.1, which proposes a pressurized air supply system for safe evacuation passages.

3)隧道安全预警与监测。3) Tunnel safety early warning and monitoring.

例如申请号为CN202220742244.7专利提出的一种高速公路隧道安全预警系统。申请号为CN202123035209.6专利提出的一种用于建筑内粉尘含量的隧道安全检测装置。For example, the application number is CN202220742244.7, which proposes a highway tunnel safety warning system. The application number is CN202123035209.6, which proposes a tunnel safety detection device for dust content in buildings.

这些研究为隧道的多种类灾害的快速、精确定位、有效诊断,从而使得调度等相关作业人员能够对灾害进行及时处置,为隧道运营安全提供保障。但以上的研究都建立在隧道通风系统状况良好的基础上,也就是说通风机(排烟风机)能够正常运行调节的基础上,对通风系统进行调控,监控和预警。在安全监测系统发生险情时,发出警报和定位等被动式服务。如何有针对性的对通风机(排烟风机)进行健康度评估和预警,起到实现通风机(排烟风机)的维护和更换的主动式提醒和安排,就成为一个迫切需要解决的工程问题。These studies are for the rapid, accurate positioning and effective diagnosis of various disasters in tunnels, so that relevant operators such as dispatchers can deal with disasters in a timely manner, and provide guarantee for tunnel operation safety. However, the above studies are all based on the good condition of the tunnel ventilation system, that is to say, on the basis of the normal operation and adjustment of the ventilator (exhaust fan), and the regulation, monitoring and early warning of the ventilation system. When a dangerous situation occurs in the safety monitoring system, passive services such as alarm and positioning are issued. How to carry out targeted health assessment and early warning of ventilators (exhaust fans), and achieve active reminders and arrangements for the maintenance and replacement of ventilators (exhaust fans), has become an urgent engineering problem to be solved .

经过工程调研,隧道风机出现问题绝大部分集中于电机的烧毁,造成烧毁的主要原因有以下三点:风机轴承振动、电机缺相以及风机抱死,致使电机过热。轴承振动涉及叶轮积尘不平衡造成的振动以及安装螺栓松动引起的振动;电机缺相包括:起动时缺相,电动机不能起动其绕组电流为额定电流的5~7倍。发热量为正常温升的15~50倍,因其迅速超过允许温升而使电动机烧毁;当满载时缺相,电动机处于过流状态即电流超过额定电流,电动机会从疲转变为堵转,未断相的线电流增加更多,引起电动机迅速烧毁;轻载运行电动机断相时,未断相的绕组电流迅速增加,使这相绕组由于温升过高而被烧毁;风机抱死是因为润滑油油质不好或者是没有润滑导致干摩擦温度急剧上升使滚珠膨胀量大于轴承间隙而抱死。另外,这些系统故障具有多发性、重复性和复杂性特点。如何通过一些必要硬件设施和科学的计算评估方法实现通风机的健康度评估,实现通风机(排烟风机)的维护和更换的主动式提醒。为此,本发明提出一种隧道通风机健康度评估方法及其系统。After engineering research, most of the problems with the tunnel fan are concentrated in the burning of the motor. The main reasons for the burning are the following three points: the vibration of the fan bearing, the lack of phase of the motor, and the locking of the fan, resulting in overheating of the motor. Bearing vibration involves the vibration caused by the unbalanced dust accumulation of the impeller and the vibration caused by the looseness of the mounting bolts; the phase loss of the motor includes: the phase loss during starting, the motor cannot start, and the winding current is 5 to 7 times the rated current. The calorific value is 15 to 50 times the normal temperature rise, and the motor will burn out because it exceeds the allowable temperature rise rapidly; when the phase is missing at full load, the motor is in an overcurrent state, that is, the current exceeds the rated current, and the motor will change from fatigue to stalled. The line current of the unbroken phase increases more, causing the motor to burn out rapidly; when the motor is running under light load, the winding current of the unbroken phase increases rapidly, causing the winding of this phase to be burned due to excessive temperature rise; the fan is locked because The quality of lubricating oil is not good or there is no lubrication, which leads to a sharp rise in dry friction temperature, which makes the ball expand more than the bearing clearance and lock up. In addition, these system faults have the characteristics of multiple, repetitive and complex. How to realize the health evaluation of the ventilator through some necessary hardware facilities and scientific calculation and evaluation methods, and realize the active reminder of the maintenance and replacement of the ventilator (exhaust fan). For this reason, the present invention proposes a method and system for evaluating the health of a tunnel ventilator.
