Recently, another invention patent of Li Changwei, a fire fighter of Shiyan City, Hubei Province, was authorized by the State Intellectual Property Office.
The invention patent is “a multi-functional amphibious work shipâ€. It combines the working principle and equipment knowledge of fire trucks. After long-term repeated design and multi-person assistance, it develops inventions by itself, and is granted the utility model patent by the National Patent Office. .
"A multifunctional amphibious workboat" can be transformed into military equipment or converted into civilian equipment. The main working principle is: the engine is connected to the driving wheel, the water jet propulsion device and the digging device or the fishing and flooding device via the transmission mechanism and the operating mechanism, and the water pumping propulsion device can be advanced in the deep water or the shallow water in the marshland. Or the silt can be propelled by the telescopic blades on the drive wheels and can travel through the drive wheels on land. In addition, there is still a lot of space in the hull, which can be used to sit or load fire-fighting equipment, and other modifications can be made.
China is a country with a vast territory. The climate, landforms and other natural conditions are diverse. In recent years, natural disasters have occurred frequently. Many fire-fighting equipment failed to fully play its role due to road reasons. This patent can be transformed into an amphibious rescue fireboat or an amphibious rescue fire truck for the current shortage of fire-fighting equipment, so that it can be used not only on land but also in shallow or deep water, maximizing the operation. Reduce the dependence on the road, and quickly send fire officers and soldiers to the scene of secondary disasters such as fires caused by natural disasters and chemical dangerous goods leaks in a flexible and maneuverable way.
In terms of civilian use, this equipment also has great practical value, which can overcome the drawbacks of traditional fishing and digging ships that can only be used in deep water.
So far, many companies have hoped to have the right to use this patent.
