Description

一种独立式发电机组减震消音器冷却结构 技术领域
本发明涉及消音冷却技术领域，具体为一种独立式发电机组减震消音器冷却结构。
背景技术
排气噪声是发动机最主要的噪声源之一，为降低发动机工作过程中的噪声，发动机上通常设置有消音器，传统的消音器直接固定在发电机上，在发电机组工作时容易产生震动，从而引起消音器的震动损坏；另外，消音器在对燃油机缸头进行减震消音时，会导致消音器整体温度升高，因此需要对消音器设置冷却机构；现有的消音器冷却系统通常与发电机组的冷却系统配合使用，通过发电机的散热气流的流动对消音器进行冷却，此种结构虽然能实现消音器的冷却，但是由于消音器的整体温度远高于发电机组排出的散热气流的温度，消音器的高温会反馈至发电机组的散热通道内，引起发电机组散热通道环境温度的增加，反而会引起发电机散热不良。
发明内容
针对上述情况，为弥补上述现有缺陷，本发明提供了一种与发电机的散热冷却系统呈分体式结构设置，且具有优良减震功能、冷却性能优良的独立式发电机组减震消音器冷却结构。
本发明提供如下的技术方案：本发明提出的一种独立式发电机组减震消音器冷却结构，包括底座、隔音罩、隔板、发电机冷却风道体、发动机、发电机本体、缸头排气管冷却风道、消音器、减震波纹管和缸头排气管，所述隔音罩设于底座的一端，所述隔板设于隔音罩内，所述隔板将隔音罩分隔为发电机冷却排热腔和消音器冷却排热腔，所述发电机冷却风道体固定设于底座上，所述发动机设于底座上，所述发动机位于发电机冷却风道体的一侧，所述发电机冷却风道体靠近发动机的一侧为非封闭式结构，所述发动机的输出轴延伸至发电机冷却风道体内，所述发动机远离发电机冷却风道体的一侧设有发动机启动拉盘，所述发动机启动拉盘上设有进风口，所述底座上设有进风槽，所述进风槽位于发动机的下方，所述发电机本体包括发电机转子和发电机定子，所述发电机转子与发动机的输出轴相连，所述发电机转子上设有反吸式风扇，所述缸头排气管冷却风道设于发电机冷却风道体一侧，所述缸头排气管冷却风道和发动机启动拉盘相连通，所述缸头排气管设于燃油机缸头上，所述缸头排气管位于缸头排气管冷却风道内，所述缸头排气管冷却风道与隔音罩相连，所述缸头排气管延伸至隔音罩的消音器冷却排热腔内，所述消音器设于消音器冷却排热腔内，所述消音器底壁上设 有排气管，所述底座上设有排气槽，所述排气管延伸至排气槽内，所述消音器上设有进气管，所述减震波纹管设于缸头排气管和消音器的进气管之间，在减震波纹管的作用下可以进行一级减震降噪，在反吸式风扇的作用下，一方面外界低温气体经过发动机启动拉盘的进风口进入缸头排气管冷却风道和发电机冷却风道体内，缸头排气管冷却风道和发电机冷却风道体分别形成了气体导向通道，保证低温气流沿着气体导向通道流动，少部分低温气体进入发电机冷却风道体内形成低温气流对发电机本体进行冷却，大部分低温气体进入缸头排气管冷却风道内形成低温气流吹向缸头、缸头排气管和消音器，从而对缸头、缸头排气管和消音器进行冷却，最后经过排气槽排出；另一方面外界低温气体经过底座的进风槽进入发电机冷却风道体内，对经过发动机启动拉盘的进风口进入的低温气体进行补充，进一步提高对发动机和发电机本体的冷却效果。
作为优选地，所述底座上设有四组减震橡胶墩，四组所述减震橡胶墩分别设于消音器下方四角位置处。
作为优选地，所述隔板为隔热板，避免消音器冷却排热腔内的高温对发电机冷却排热腔内温度造成影响。
采用上述结构本发明取得的有益效果如下：本发明提出的一种独立式发电机组减震消音器冷却结构，通过隔音罩以及其内的隔板的设置，将发电机的散热冷却区域与消音器的散热冷却区域分隔开来，避免消音器的高温对发电机进行反向影响；并通过消音器冷却排热腔的设置，为消音器提供独立式的放置区间，解决了消音器直接设置在发电机上引起震动损坏的问题，并通过减震波纹管和减震橡胶墩的配合，配合消音器实现了减震消音的功能，同时，通过发动机启动拉盘的进风口与底座进风槽的设置，在反吸式风扇的转动产生的负压的作用下，将低温气体从发动机启动拉盘的进风口和底座的进风槽引入缸头排气管冷却风道与发电机冷却风道体内，分别对缸头排气管、消音器和发电机本体进行高效冷却，提高了整体的冷却效率。

如图2、图3、图4和图5所示，本发明采取的技术方案如下：一种独立式发电机组减震消音器冷却结构，包括底座1、隔音罩2、隔板3、发电机冷却风道体4、发动机5、发电机本体、缸头排气管冷却风道6、消音器7、减震波纹管8和缸头排气管9，隔音罩2设于底座1的一端，隔板3设于隔音罩2内，隔板3将隔音罩2分隔为发电机冷却排热腔10和消音器冷却排热腔11，发电机冷却风道体4固定设于底座1上，发动机5设于底座1上，发动机5位于发电机冷却风道体4的一侧，发电机冷却风道体4靠近发动机5的一侧为非封闭式结构，发动机5的输出轴延伸至发电机冷却风道体4内，发动机5远离发电机冷却风道体4的一侧设有发动机启动拉盘12，发动机启动拉盘12上设有进风口13，底座1上设有进风槽14，进风槽14位于发动机5的下方，发电机本体包括发电机转子和发电机定子，发电机转子与发动机5的输出轴相连，发电机转子上设有反吸式风扇15，缸头排气管冷却风道6设于发电机冷却风道体4一侧，缸头排气管冷却风道6和发动机启动拉盘12相连通，缸头排气管9设于燃油机缸头上，缸头排气管9位于缸头排气管冷却风道6内，缸头排气管冷却风道6与隔音罩2相连，缸头排气管9延伸至隔音罩2的消音器冷却排热腔11内，消音器7设于消音器冷却排热腔11内，消音器7底壁上设有排气管16，底座1上设有排气槽17，排气管16延伸至排 气槽17内，消音器7上设有进气管18，减震波纹管8设于缸头排气管9和消音器7的进气管18之间。
其中，底座1上设有四组减震橡胶墩19，四组减震橡胶墩19分别设于消音器7下方四角位置处。隔板3为隔热板，避免消音器冷却排热腔11内的高温对发电机冷却排热腔10内温度造成影响。
具体使用时，本发明提出的一种独立式发电机组减震消音器冷却结构，通过隔音罩2以及其内的隔板3的设置，将发电机的散热冷却区域与消音器7的散热冷却区域分隔开来，避免消音器7的高温对发电机进行反向影响；并通过消音器冷却排热腔11的设置，为消音器7提供独立式的放置区间，解决了消音直接设置在发电机上引起震动损坏的问题，并通过减震波纹管8和减震橡胶墩19的配合，配合消音器7实现了减震消音的功能；同时，在反吸式风扇15的作用下，一方面外界低温气体经过发动机启动拉盘12的进风口13进入发电机冷却风道体4和缸头排气管冷却风道6内，发电机冷却风道体4和缸头排气管冷却风道6分别形成了气体导向通道，保证低温气流沿着气体导向通道流动，少部分低温气体进入发电机冷却风道体4内形成低温气流对发电机本体5进行冷却，大部分低温气体进入缸头排气管冷却风道6内形成低温气流吹向缸头、缸头排气管9和消音器7，从而对缸头、缸头排气管9和消音器7进行冷却，最后经过排气槽17排出；另一方面外界低温气体经过底座1的进风槽14进入发电机冷却风道体4内，对经过发动机启动拉盘12的进风口13进入的低温气体进行补充，进一步提高对发动机和发电机本体5的冷却效果。
要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物料或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物料或者设备所固有的要素。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
