Description

Wall penetrating hole sealing structure of amphibious vehicle Technical Field The utility model belongs to the technical field of amphibious vehicles, and particularly relates to a wall penetrating hole sealing structure of an amphibious vehicle. Background When the amphibious vehicle is arranged in a pipeline and part of components (parts) are installed, a plurality of wall penetrating holes are arranged on the vehicle body, and the wall penetrating holes are used for passing through the pipeline and fasteners. When the amphibious vehicle is assembled, sealing measures are needed to be taken for gaps between the wall penetrating holes and the passing components, otherwise, leakage can be generated at the positions when the wall penetrating holes are immersed below a waterline, and sealing performance and amphibious vehicle navigation safety are affected. The sealing scheme of the matching position of the existing wall penetrating hole, the pipeline joint and the bolt is to smear sealant, and waterproof sealing is realized by means of the sealant gathered at the clearance and the cohesiveness of the sealant. The clearance between the wall penetrating hole and the matched position of the outer diameter of the pipe joint and the bolt is smaller, so that sufficient sealant is difficult to fill, and the diameter of the steps of the end faces of the pipe joint and the bolt beyond the wall penetrating hole is also smaller, so that sufficient sealant is difficult to fill. In order to realize sealing, a certain amount of sealing colloid is smeared at the positions of the circumferences of the wall penetrating holes beyond the steps of the end faces of the pipe joint and the bolt, so that a phenomenon that the sealing colloid overflows in a large amount is generated. The sealant is easy to loosen and peel off when in vibration and external force impact, is directly exposed and can be accelerated to age after being subjected to illumination and water bubbles, so that the adhesiveness is affected, and the tightness of a vehicle body is affected. The prior art has the technology of being named as an amphibious armored vehicle floating assisting device and the technology with the public (bulletin) number of CN108928196A, and relates to a floating assisting device, in particular to a floating assisting device matched with the amphibious armored vehicle on water, which is mainly used for solving the technical problem that the amphibious armored vehicle is lack of self-rescue means when the vehicle body is in water distress in the use state on water. The floating-assisting device comprises an even-number group floating-assisting assembly and a centralized control system, wherein the single-number group floating-assisting assembly consists of a floating body system, a gas generating device, an air charging pipeline, a frame and mounting accessories, the floating body system is arranged in the frame and is connected with the gas generating device through the air charging pipeline, and the frame is fixedly arranged on two sides of a vehicle body through the mounting accessories. The control system can adopt a plurality of control modes such as pure pneumatic control, wired electric control, wireless remote control and the like, is characterized in that the control system is mainly installed in a vehicle, can start the system by one key under the condition of not taking out of a cabin, provides buoyancy for the vehicle, has the characteristics of convenient operation, quick unfolding, easy maintenance, safety, reliability and reusability, and can be widely applied to amphibious armored vehicles of various models.
