Flat pressing assembly, display ship with automatic charging function and charging port

Abstract

The invention discloses a flat pressing assembly, a display ship with an automatic charging function and a charging port. A flat pressing mechanism comprises a piston and an inner box, wherein the piston is sealed with the outer side of an adjusting inner barrel and can be axially assembled in a sliding mode. A first limiting partition plate is sequentially fixed to the adjusting inner barrel fromtop to bottom in a sealed mode. An adjusting barrel is located between a second limiting partition plate and a supporting partition plate. A penetrating barrel wall communicating hole is formed in the portion, loaded into the inner cavity, of the adjusting inner barrel and can allow the adjusting barrel to communicate with the inner cavity. One end of an air passing cylinder is assembled and fixed to a piston, and the other end of the air passing cylinder penetrates through the first limiting partition plate and the second limiting partition plate and then is assembled and fixed with the adjusting air bag. The adjusting air bag is located between a limiting air passing ring and the first limiting partition plate. An adjusting cavity is formed in the adjusting air bag and communicated withone end of an air passing inner barrel arranged on the air passing barrel, the other end of the air passing inner barrel penetrates through the piston and then is communicated with the portion, located between the piston and the supporting partition plate, of the adjusting inner barrel, and the adjusting inner barrel of the portion is further communicated with an inner tank of the air tank through a connecting air pipe.

Description

technical field [0001] The invention relates to water surface floating equipment, in particular to a flat pressing assembly and a display boat with automatic charging function and a charging port. Background technique [0002] In places with large lakes, reservoirs, etc., it is generally difficult to set up advertisements or display devices on the water surface. At present, the main method is to spray or paste advertisement patterns on the boat, and then obtain the display effect by manually sailing the boat. Obviously, this method has a higher cost and is only suitable for places with larger lakes. In addition, in places with remote reservoirs, it is generally necessary to set up warning signs, especially in water sources, and it is generally necessary to prohibit swimming in the water, washing clothes, and sewage discharge. At present, artificial patrols or remote monitoring of cameras are mainly used, and the cameras are mainly installed on the shore, and there are many ...

Problems solved by technology

At present, artificial patrols or remote monitoring of cameras are mainly used, and the cameras are mainly installed on the shore, and there are many dead spots. It is obviously unrealistic to use a large number of cameras for monitoring. Therefore, there are still management loopholes
