Description

用于多功能除雪车吹雪矢量风口的结构 技术领域
本发明属于道路养护车辆领域，尤其涉及到一种用于多功能除雪车吹雪矢量风口的结构。
背景技术
冬季降雪对道路交通往往产生直接和显著的影响。因降雪导致的公路交通中断、铁路停运、机场关闭、城市交通堵塞甚至瘫痪的事件屡屡发生，对工农业生产和人民生活产生严重影响，往往造成严重的经济和社会损失。
路面积雪结冰的危害十分严重。结冰路面的摩擦系数降低,车辆刹车距离增大,我国冬季有30％左右的交通事故是由路面结冰引起的。路面积雪结冰不仅容易引发交通事故,严重时还会造成公路交通中断、铁路停运、机场关闭,严重影响人民生活和工农业生产,给国家经济造成严重损失。
有效清除冬季道路的积雪，保障交通安全，保护环境，道路冰雪清除设备是非常必要的，用于清除路面冰雪,保障车辆、飞机和行人安全的冬季路面养护设备具有十分重要的意义。
冷吹扫的实现方法是用大功率柴油机通过传动装置带动鼓风机工作，来提供冷吹扫动力，这样可消除喷气式除雪车高温气流的不利因素，实现节省燃油，降低燥音，减少污染，减少对机场设施的破坏目的。
吹扫作为一种清扫方式，就是利用强大的气流来清除高等级公路或机场上的杂物或积雪。大型吹扫机械分为三大类：1)利用大功率发动机带动鼓风机旋转来产生吹扫力；2)利用飞机发动机的尾气产生吹扫力；3)多功能除雪机械具有吹扫功能，利用液压马达通过传动装置带动鼓风机旋转，进行吹扫作业。
每种吹扫方式有不同的特点，利用大功率发动机带动鼓风机吹扫时，其吹扫力由所配备的发动机功率、鼓风机功率、及二者之间的匹配性决定，可根据使用要求进行选择；利用飞机发动机尾气进行吹扫作业时，其风力一般都能满足要求，但是由于尾气产生几百度的高温，还有很高的噪音和很大的污染。
申请号为CN201120060730.2的专利中描述了一种可调整位置的吹雪装置，还可提供一种可调整出风口大小的吹雪装置。它包括吹雪口箱体总成，其特征是在吹雪口箱体总成与车架之间铰接有等长且等距的两根连杆总成，两根连杆总成与吹雪口箱体总成和车架组成四连杆机构；还设置有连接吹雪口箱体总成和车架的伸缩油缸。但该结构仅可以调节风口开度，不可以实现风口方向的任意调节。
申请号为CN200820027701.4的专利中描述了一种用于清除除雪车下的局部积雪的活动吹雪装置，设有汽车底盘和送风机构，送风机构包括送风管和吹风管，其主要特征在于汽车底盘前端分别设有升降机构和送风分配管，升降机构设有固定杆、活动杆、连接杆和液压油缸，固定杆固定在汽车底盘上，活动杆经连接杆与固定杆相连接，液压油缸的一端与固定杆相铰接，另一端与连接杆相铰接，送风管一端与活动杆相铰接，另一端经铰链式接头与送风分配管相连接，送风分配管上设有多个吹风管。但该结构仅可以调节风口高度。
针对上述存在的问题，本发明采用合理的出口排气结构设计，出风喷口采用方形结构、调节风道采用喉结结构设计，能在吹雪风口在水平面转动±20°，垂直平面内转动±20°，解决吹管路向前、对地角度及离地高度调节的难题；调节风道喉结卡环结构采用渐缩圆转方结构，减少风道的局部压力损失，提高了送风系统的效率。
发明内容

所述外喉结(5)的出风口为扁平口结构形式。
所述内喉结(3)和外喉结(5)之间设置有对应的用于安装所述密封环(6)的安装槽。
本发明的优点是：本发明提供一种用于多功能除雪车吹雪矢量风口的结构，出口为扁平口，提高单位时间内吹雪量。在高速气流作用下，作跃移运动的雪粒速度不断增加，雪粒的动能增大，通过不断与积雪表面的其他雪粒发生碰撞，将带动更多的、新的雪粒脱离积雪表面随着气流运动。气流作为雪粒前进的动力，不断与雪粒发生能量交换，本身的动量逐渐减少，而吹雪量不断增加。

下面对本发明做出进一步说明，以更好了解本发明：除雪车吹雪作业的特征是利用吹雪风口的打击力、吹雪风口单位面积打击能量和气流的方向这三个重要参数实现除雪车吹雪作业能力。除雪车吹雪系统通过控制气流压力实现吹雪打击力和单位面积打击能量，通过吹雪矢量风口控制气流的方向。
在除雪车吹雪作业时，由吹雪风口的高速气流，是以剧烈的湍流运动作用在积雪表面，射流流场的压力分布、速度分布、湍动能分布都影响着吹雪车的吹雪效率。
高速气流经过吹雪风口，以射流的形式作用在积雪表面上，不同形状的吹雪风口可以形成不同的吹雪风口射流流场，吹雪风口中心的风速度也有明显的不同，这就导致了吹雪效果的不同。
影响吹雪风口吹雪性能的参数主要有：吹雪风口流量、吹雪风口角度、吹雪风口力度和出口压力等。
吹雪风口的设计要能使吹雪风口出口处气流获得最大的有效动量。吹雪风口对流体有增速和减压的作用，本专利实现要点：除雪车吹雪作业时，受作业环境、场地风力的影响，吹雪风口在水平面转动±20°，垂直平面内转动±20°。
