压力开关151是指采用高精度、高稳定性能的压力传感器和变送电路，再经专用CPU模块化信号处理技术，实现对介质压力信号的检测、显示、报警和控制信号输出。压力开关151可以安装在进风管道上，也可以安装在柴油机增压器中，在此并不做具体限定。可选的，压力开关151可以电动控制，也可以是手动控制。
压力开关151与第一电磁阀141电连接，当进风口滤网300被杨柳絮、灰尘等附着物发生堵塞时，进风管道中的进气量减少，柴油机增压器进气口的压力会显著增加，当压力增加至影响柴油机的正常运行时，柴油机增压器空气进口压力传感器200会将压力信号传递给压力开关151，压力开关151控制第一电磁阀141开启，以使气缸110与吹扫管组之间的管路导通，使得气缸110中的高压气体经第一电磁阀141、连接管道111进入吹扫管组，待吹扫管组沿滑道向上运动至导向杆的上端，第一电磁阀141关闭，吹扫管组在自身重力作用下回落至导向杆的下端，手动控制压力开关151控制第一电磁阀141开启第一电磁阀141，吹扫管组重复上述动作，当进风口滤网300上的杨柳絮、灰尘等附着物被清除至不堵塞进风口滤网300时，进风管道中正常进气，柴油机增压器进气口的压力恢复正常，安装在柴油机增压器上的柴油机增压器空气进口压力传感器200将压力信号传递给压力开关151，压力开关151控制第一电磁阀141关闭，以使气缸110与吹扫管组之间的管路断开，使得气缸110中的高压气体无法流入吹扫管组，对进风口滤网300的吹扫过程结束。
本实施例提供的进风口清理装置100，通过在气缸110与吹扫管组之间设置第一电磁阀141，通过设置压力开关151，并通过压力开关151与第一电磁阀141电连接，使得压力开关151通过柴油机增压器空气进口压力传感器 200的压力变化控制第一电磁阀141的开启与关闭，进而实现气缸110与吹扫管组之间的通断，使得驾驶员能够掌握进风口滤网300的堵塞情况，且提高了进风口清理装置100的工作效率。
进一步地，控制阀门还包括：第二电磁阀142；导向杆的一端设置有第一触点电磁开关161，导向杆的另一端设置有第二触点电磁开关162，第一触点电磁开关161位于第二触点电磁开关162上方，第一触点电磁开关161及第二触点电磁开关162都与第二电磁阀142电连接；其中，吹扫管组在滑道中运动至上极限位置时推抵第一触点电磁开关161，以使第一触点电磁开关161控制第二电磁阀142断开吹扫管组与气缸110之间的通路；吹扫管组在滑道中运动至下极限位置时推抵第二触点电磁开关162，以使第二触点电磁开关162控制第二电磁阀142导通吹扫管组与气缸110之间的通路。
示例性地，第二电磁阀142可以安装在第一电磁阀141与吹扫管组相连的管道上。
可选的，第一导向杆131的上端可以设置有第一触点电磁开关161，第一导向杆的下端可以设置有第二触点电磁开关162，其中，第一触点电磁开关161固定在第一导向杆131的上端，比如，第一触点电磁开关161上设有安装孔，第一导向杆131的上端设有螺纹孔，螺栓穿过第一触点电磁开关161的安装孔后插设在第一导向杆131的螺纹孔中，以使第一导向杆131与第一触点电磁开关161紧固连接。
第一触点电磁开关161上设有触点，可选的，第一导向杆131的上端设有导向杆安装孔，上支架133的对应位置设有上支架安装孔，第一触点电磁开关161上的触点可以通过导向杆安装孔、上支架安装孔伸出至第一滑道的上端，并与第一滑道连通。
第二触点电磁开关162固定在第一导向杆131的下端，比如，第二触点电磁开关162上设有安装孔，第一导向杆131的下端设有螺纹孔，第一下支架134的对应位置设有安装孔，螺栓穿过第二触点电磁开关162的安装孔、第一下支架134的安装孔后插设在第一导向杆131的螺纹孔中，以使第一导向杆131与第二触点电磁开关162紧固连接。第二触点电磁开关162上设有触点，可选的，第一导向杆131上的第一滑道贯穿第一导向杆131的下端，第一下支架134上设有下支架安装孔，第二触点电磁开关162上的触点通过 下支架安装孔伸出至第一滑道的下端，并与第一滑道连通。

可选的，第一触点电磁开关161及第二触点电磁开关162都与第二电磁阀142电连接，以便于第一触点电磁开关161、第二触点电磁开关162控制第二电磁阀142的打开与闭合，以使吹扫管组与气缸110在导通与断开之间切换。其中，第二电磁阀142的初始状态为导通吹扫管组与气缸110之间的通路。
当压力开关151控制第一电磁阀141开启后，由于第二电磁阀142处于初始状态，因此，气缸110与吹扫管组之间的通路导通，气缸110为吹扫管组提供高压气体，吹扫管组受到高压气体的推力，使得吹扫管组在滑道中运动至上极限位置，与吹扫管组相连的滚动轴承136与第一触点电磁开关161的触点接触并推抵第一触点电磁开关161，使得第一触点电磁开关161控制第二电磁阀142断开吹扫管组与气缸110之间的通路，气缸110不再为吹扫管组供气；吹扫管组在自身重力作用下沿滑道回落，使得吹扫管组在滑道中运动至下极限位置，与吹扫管组相连的滚动轴承136与第二触点电磁开关162的触点接触并推抵第二触点电磁开关162，使得第二触点电磁开关162控制第二电磁阀142导通吹扫管组与气缸110之间的通路，气缸110为吹扫管组提供高压气体，吹扫管组重复上述操作，直至柴油机增压器空气进口压力传感器200所传输的压力信号正常，压力开关控制第一电磁阀141关闭，气缸110不再为吹扫管组供气，对进风口滤网300清理完毕。
值得注意的，此处的上极限位置指的是吹扫管组沿滑道运动至导向杆的上端，并且滚动轴承136与第一触点电磁开关161的触点接触并能够推抵第一触点电磁开关161时的位置；此处的下极限位置指的是吹扫管组沿滑道运动至导向杆的下端，并且滚动轴承136与第二触点电磁开关162的触点接触并能够推抵第二触点电磁开关162时的位置。
本实施例提供的进风口清理装置100，通过在第一电磁阀141与吹扫管组之间设置第二电磁阀142，通过在导向杆的上端设置第一触点电磁开关161，在导向杆的下端设置第二触点电磁开关162，通过将第一触点电磁开关161及第二触点电磁开关162分别设置为与第二电磁阀142电连接，通过吹 扫管组在滑道中的上下运动，以使第一触点电磁开关161和第二触点电磁开关162分别控制第二电磁阀142，使得第二电磁阀142控制气缸110与吹扫管组之间的通断，实现对进风口滤网300的自动清理，提高了工作效率。
进一步地，导向杆的上端安装有第一弹性件171，第一弹性件171的上端与第一触点电磁开关161相抵，吹扫管组运动至上极限位置时与第一弹性件171共同推抵第一触点电磁开关161。

当吹扫管组运动至上极限位置时，与吹扫管组相连的滚动轴承136推抵挡板向上移动，以使与挡板相连的第一弹性件171向上运动并推抵第一触点电磁开关161的触点，使得第一触点电磁开关161控制第一电磁阀141动作。
本实施例提供的进风口清理装置100，通过在导向杆的上端安装第一弹性件171，通过将第一弹性件171的上端与第一触点电磁开关161相抵，一方面能够防止吹扫管组撞击到上支架而损坏，另一方面，第一弹性件171能够与吹扫管组共同推抵第一触点电磁开关161，便于对第一触点电磁开关161进行精确控制。

当吹扫管组运动至下极限位置时，与吹扫管组相连的滚动轴承136推抵挡板或第二弹性件172向下移动，以使第二弹性件172向下运动并推抵第二触点电磁开关162的触点，使得第二触点电磁开关162控制第一电磁阀141动作。
本实施例提供的进风口清理装置100，通过在导向杆的下端安装第二弹性件172，通过将第二弹性件172的下端与第二触点电磁开关162相抵，一方面能够防止吹扫管组撞击到下支架而损坏，另一方面，第二弹性件172能够与吹扫管组共同推抵第二触点电磁开关162，便于对第二触点电磁开关162进行精确控制。
进一步地，安装支架包括：两个平行设置的安装杆，多个吹扫管组间隔固定在两个安装杆之间。

采用本实施例提供的进风口清理装置100，当吹扫管组通过滑道向上运动时，固定在吹扫管组上的毛刷先对进风口滤网300进行刷扫，然后吹扫管组对进风口滤网300进行喷气；当吹扫管组通过滑道向下运动时，固定在吹扫管组上的毛刷会继续对进风口滤网300进行刷扫。
本实施例提供的进风口清理装置100，通过在吹扫管组上固定毛刷180，通过将毛刷180的头部设置为朝向进风口滤网300，使得毛刷180随着吹扫管组的上下运动均能对进风口滤网300进行刷扫，提高了清理进风口滤网300的效率。
