Description

输电线路山火高压灭火水枪 技术领域
本发明涉及灭火装置领域，尤其是一种输电线路山火高压灭火水枪。
背景技术
受春节、春耕、清明、秋收等工农业生产生活用火习俗的影响，当遭遇持续干燥的天气时，输电线路走廊易爆发大面积山火，引起线路山火跳闸；然而，长期以来，电力部门因长期缺乏安全有效的灭火装备，为了确保人身安全，即使发现了输电线路山火，也一般不采取灭火措施；这种处理方式，使得部分山火在发现后进一步蔓延、扩大，最终引发输电线路跳闸。
现有的森林防火部门灭火装备，如消防车、灭火直升机等，均体积庞大，价格高昂，一方面由于运输困难难以较快到达输电线路山火发生地点，另一方面由于装备复杂，需要专业的消防员进行操作，较难适应数量众多的输电线路小范围山火灭火要求。
目前，市面上有一些林火细水雾扑灭装备，但其雾化通道为直线型，水滴相互碰撞少，雾化效果不理想；另一方面，现有林火扑灭装备细水雾切换机构复杂，长期使用后容易生锈冻结，使得切换机构坏死。这种装备对输电线路山火分布广泛、地形复杂、火场面积小、火场缺少水源的特点同样不适合。
因此如何快速有效地扑灭输电线路引起的山火，提高输电线路山火应急处置能力，以防止输电线路跳闸、减少损失是目前亟待解决的问题。
发明内容
本发明旨在提供一种输电线路山火高压灭火水枪，以快速有效地扑灭输电线路引起的山火，防止输电线路跳闸。
本发明提供的这种输电线路山火高压灭火水枪包括汽油发动机、减速器、水袋、高压水泵和细水雾枪头，所述汽油发动机通过减速器与高压水泵连接， 高压水泵与水袋连接，向细水雾枪头送水；所述细水雾枪头包括入水槽、枪体、细水雾转换阀、直射水槽、细水雾螺旋水槽，所述细水雾转换阀安装在枪体中能在外力作用下作工位移动，该细水雾转换阀上有一个转换水槽，该转换水槽能随所述细水雾转换阀的工位移动一端与入水槽连通，另一端与直射水槽或者与细水雾螺旋水槽连通；细水雾螺旋水槽至少一个，并且每个细水雾螺旋水槽都有细水雾喷孔。
为了进一步提高灭火效果，所述汽油发动机(1)采用两冲程三菱TB50发动机，排量为50cc。在同一条细水雾螺旋水槽上设置两个所述细水雾喷孔。所述直射水槽的直射喷孔直径大于细水雾喷孔的直径。所述直射喷孔(5.8)直径为1.4mm，所述细水雾喷孔(5.8)的直径为0.7mm。所述细水雾枪头(5)整体材质采用不锈钢，所述细水雾转换阀(5.3)为圆柱形。
本发明由于有直射和螺旋雾化喷射两种模式，雾化喷射采用的是螺旋喷射，当细水雾转换阀切换到雾化喷射状态时，水流在细水雾螺旋水槽中做加速运动，使得水流相互碰撞，破坏水的凝聚力，在高压作用下水流通过细水雾喷孔喷出去，形成包络面积宽并且雾化浓度大的细水雾，细水雾平均直径可达到500μm以下，雾化效果较好，相比现有技术用水相对较节约，并且本发明两种模式的转换非常简单而快捷，在灭火的时候可以迅速切换模式，因此本发明尤其适用于山火分布广泛、地形复杂、火场面积小、火场缺少水源的情况，有效防止因山火的蔓延、扩大引发的输电线路跳闸现象。为输电线路山火提供了快捷实用的灭火装备。

具体实施方式
实施方式一：从图1可以看出本发明具有汽油发动机1、减速器2、水袋3、高压水泵4和细水雾枪头5，汽油发动机1的转轴与减速器2连接，减速器2与高压水泵4的转轴连接，高压水泵4的入水口通过水管与水袋3连接，高压水泵4出水口与细水雾枪头5通过水管连接；在本实施方式中汽油发动机1采用两冲程三菱TB50发动机，排量为50cc，使得整机输出功率大、水压高、射程远达8.12米。
图2和图3反映了细水雾枪头5的结构，从图2可以看出细水雾枪头5主要由入水口5.1、枪体5.2、细水雾转换阀5.3、转换水槽5.4、直射水槽5.5、细水雾螺旋水槽5.6、直射喷孔5.7、细水雾喷孔5.8组成。细水雾转换阀5.3为圆柱形不锈钢柱，安装在枪体5.2中，转换水槽5.4设在细水雾转换阀5.3上，入水口5.1、直射水槽5.5、细水雾螺旋水槽5.6、直射喷孔5.7、细水雾喷孔5.8均设在枪体5.2上，细水雾转换阀5.3一端与入水口5.1连通，另一端与直射水槽5.5或细水雾螺旋水槽5.6连通。细水雾转换阀5.3可以在外力作用下上下移动，比如直接用手指上顶或者下按该转换阀，使转换水槽5.4与直射水槽5.5或细水雾螺旋水槽5.6连通，对射水模式进行直喷或者螺旋雾喷的模式转化，当转换水槽5.4与直射水槽5.5连通时，枪头工作在直射喷水模式，水柱从直射喷孔5.5喷出；当转换水槽5.4与细水雾螺旋水槽5.6连通时，枪头工作在细水雾喷水模式，水流通过螺旋式水槽做加速运动，使得水流相互碰撞，破坏水的凝聚力，在高压作用下，做离心运动从细水雾喷孔5.8喷出，在本实施方式中细水雾喷孔5.8采用了两个，直径均设为0.7mm，直射喷孔的直径设为1.4mm。细水雾枪头5整体材质采用316 不锈钢以防生锈。经检测本实施方式的形成的细水雾效果较好，细水雾平均直径可达到500μm以下。
实施方式二：对于本发明而言，细水雾螺旋水槽5.6不限于一条，也可以是两条，此时转换水槽5.4的孔径相对实施方式一可以更大些，以使枪头工作在细水雾喷水模式转换水槽5.4能与两条细水雾螺旋水槽5.6同时连通。
