Description

灯柱框架式路面风力挡雪屏
所属技术领域
一种能够使局部地面的不遭积雪覆盖的灯柱框架式路面风力挡雪屏。该装置主体部分是由不同规格的风管在所保护路面上方搭建的棚架,框架的立柱可以兼做路灯的灯柱;由空气压缩机(下文简称风泵)泵出的高压风输送到搭建棚架的风管,高压风从管路上喷头喷出形成密集的风束屏障,阻挡框架外缘漂落的雪花不能进入所保护的路面,故名灯柱框架式路面风力挡雪屏。其作用是让被保护的界面不遭受积雪覆盖,同时不影响各种移动物体在框架内正常通过,尤其适用于保护高速铁路、高速公路的路面不被积雪所覆盖。
背景技术
目前,公知的公路、铁路遭受大雪覆盖后,既有的技术是耗费大量的人力、物力,用除雪机械、撒融雪剂或使用便携式吹风机来清理路面上的积雪。不论哪一种方法,都存在积雪清理不及时,积雪被压实难以清理,封锁路段影响车辆正常通行的弊端。
发明内容
为了解决这些问题,本技术方案提供一种灯柱框架式路面风力挡雪屏,该挡雪屏能够通过高压风力将天空漂浮的雪花吹出公路、铁路以及所有被保护的界面之外,使之不遭受大雪的覆盖,保证车辆在大雪天正常通行。
本发明案例解决其技术问题所采用的技术方案是:在公路、铁路以及其他被保护界面外缘和上方,用风管搭建起由多个单元组成的与道路等长的框架式管路棚。框架立柱安装在道路两侧,同时可以兼做路灯的灯杆,也可利用既有的灯杆进行改造,主风管在路基两侧,延路基边缘与道路平行铺设,顶棚管路通过人字梁风管架在空中,侧墙风管垂直立于主风管之上,人字梁风管两端与立柱顶端相联,与顶棚风管垂直相联贯通,每个框架管路棚为一个单元,根据被保护路面的长度,将N个单元框架式管路棚相互连接组合在一起,形成一个与被保护道路等长防雪屏障。通过风泵产生高压风源,将高压风送入储风缸,在通过管路输送到用风管搭建起的框架棚。侧墙风管、顶棚风管上都设有喷头安装座,喷头采用快捷、密封的连接方式,固定在管路上,随时可以更换。高压风进入侧墙风管,顶棚风管后通过风管喷头上的多个排风孔,按设定的方向吹向空中,形成强力的风束墙,阻挡框架侧面即道路两侧飘落的雪花不能进入框架保护界面内,顶棚风管把框架上空的飘落的雪花分层次,一级一级吹到保护界面外。
本技术方案的有益效果是:保证路面上不被积雪覆盖,减少交通不便,保证交通安全,节省大量的人力、物力和机械清雪的成本。

具体实施方式
在图1中,从第一单元体入口2至快速接头8为一个单元体,在一段路面上,根据道路的长短,由N个单元体连接,组合成一个与道路等长的挡雪屏。每X个单元体设置一套风泵13,风缸截止阀14,风缸15,主管截止阀16,风压调节器17。X的具体数根据风泵的供风能力和每个单元体的长短试验而定。选择功率大的风泵,供应X的数量多些,选择功率小的风泵,供应X的数量少些,风泵的选择根据现场需要设计。风泵的启动采取微机集中控制,总控室根据监控到的下雪情况,随时可以开通任何路段上的任意一个风泵。
下雪前,通过风泵控制器11,启动风泵13,开通风缸截止阀14,将风缸15注满高压风,将风压调节器17调至规定压力。在下雪时,再次及时启动风泵13,使之连续工作直至下雪停止,开通单元截止阀16,向各个单元体内充风,压力风通过主风管10→侧墙风管20→前立管22→人字梁风管3→后灯柱立管1→顶棚风管9最后充满各个单元体。
充满压力风的侧墙风管20,通过侧墙喷头19上的排风孔24向外吹风,形成侧墙风力屏障,侧墙高压风束18将道路两侧的飘落的雪花向外前方吹出,使道路两侧飘落的雪花被阻隔在道路外侧。
充满压力风的顶棚风管9,通过顶棚喷头5上的排风孔24向外吹风,形成顶棚风力屏障,顶棚高压风束7将道路上空的飘落的雪花不停地、分层次地、一级一级吹向道路两侧。排风的角度可通过风管转角调节器4来调整,通过调整排风角度可以更加可靠的将飘落的雪吹出保护界面。
顶棚风管9的相互之间的间距是根据道路的宽窄而定的,道路越宽,风管的根数越多,具体间距通过通风试验来确定,高一层风管的压力风一定要将飘落的雪吹到低一层的风管前,再由低一层的风管继续向外吹,直至吹出路面。
侧墙风管20相互之间的间距也是根据试验而定,两根侧墙风管相对,向外前方吹出压力风,必须形成交叉重叠,所形成的风束屏,其压力要远远大于自然风的风力,才能阻断飘落雪花不会进入路面。
图2重点反映顶棚喷头5与锁紧安装座6的联接关系。锁紧安装座6一端拧入顶棚喷头,然后通过前锁紧螺母25锁紧,另一端固定在顶棚风管9的安装座27上,通过后锁紧螺母26锁紧。侧墙喷头19与侧墙风管20采取同样的安装方式。
在图2中,排风孔24的孔径¢的大小根据试验确定,两孔之间的距离(H)也是根据试验确定的。
