Can cover structure used in fire-fighting vehicle

Abstract

The invention relates to a pot cover of fire-fighting truck, wherein it comprises the pot cover base at the top of liquid storage pot while it is through to the pot chamber, and a pot cover on the base; the center of pot cover has a cover hole; the outer side of pot cover relative to the cover hole has overflow ventilate cap with the first ventilate overflow hole; the inner side of pot cover relative to the cover hole has the water inlet anti-splash cap with the second ventilate overflow hole; the water inlet anti-splash cap and the overflow ventilate cap are relative; since said pot cover hasoverflow function, it can avoid ventilate overflow open at the top of storage pot. And the first ventilate overflow hole can avoid blocking.

Description

technical field [0001] The invention relates to a tank cover structure for a fire truck, which is an improvement to the existing tank cover structure on a liquid storage tank of a fire truck, and belongs to the technical field of fire fighting equipment. Background technique [0002] In the prior art, the tank cover structure on the top of the fire truck's liquid storage tank (also known as the water tank) plays a monotonous role, and only plays the role of opening or closing the manhole. When firefighters need to inspect, clean or even repair the cavity of the liquid storage tank, the tank cover is opened for firefighters to enter and exit through the manhole, and vice versa. E.g Figure 4 As shown, a tank cover seat 1 (also called a manhole cover seat) is extended on the top of the liquid storage tank 3 of the fire truck 8, and a tank cover 2 (also called a manhole cover) is arranged on the top of the tank cover seat 1. ), and the top of the liquid storage tank 3 is also ...

Problems solved by technology

[0003] The above illustrations confirm that the can lid structure described by the applicant has a single purpose and cannot be used for other functions. They are not related to each other, and each has its own function, thus leading to the following four technical problems. The first is to cause the overall structure of the liquid storage tank 3 to be messy. characteristics, so the coexistence of the tank cover structure and the vent overflow port 7 is contrary to simplicity; the second is to configure the tank cover structure and the vent overflow port 7 on the liquid storage tank 3, which will not only increase the processing of the liquid storage tank 3 Difficulty, and it will increase the processing cost and the troublesomeness of use and maintenance; the third is that the tank cover structure and the ventilation overflow port 7 are not enough to reflect the economy of materials used in processing; When it is used in the area, its nozzle is easy to freeze and damage, or even blocked, causing the tank body of the liquid storage tank 3 to expand, deform and damage due to overpressure when adding liquid
