[0002] With the continuous upgrading of products, the performance monitoring requirements for marine engines have become more stringent. In addition to the temperature monitoring of the main system pipelines of marine engines, shipyards have also begun to require the measurement of the crosshead temperature of each cylinder of the marine engine, so it is necessary to install a temperature sensor on the engine crosshead.
[0003] Because the engine crosshead will generate high temperature when in use, and when the temperature of the engine crosshead is too high, it will cause burns and damage to the internal circuit boards and lines of the engine, and then damage the engine. Therefore, it is very necessary to use a temperature detection device to detect and monitor the real-time temperature of the engine crosshead. It can serve as a warning when the temperature of the engine crosshead is too high. For this reason, we will install the temperature sensor on the engine crosshead; however, when the engine is working, the crosshead connected to it will also generate high temperature, and the high temperature will also cause damage to the temperature sensor directly placed on the engine crosshead. Therefore, we propose a mounting bracket for the crosshead temperature sensor of a marine engine. Utility Model Content
