Emergency water drainage device with water level indicating function

Abstract

The invention discloses an emergency water drainage device with a water level indicating function. The water drainage device is located on a floating disc, and comprises a water drainage piece, wherein the water drainage piece comprises a supporting frame, the supporting frame is provided with an indicating piece and an identifying piece, the supporting frame comprises a connecting pipe body, thewater drainage piece is mounted on a mounting hole in a sealing mode through the connecting pipe body, one end of the connecting pipe body is provided with a water seal groove barrel, the other end ofthe connecting pipe body is provided with a water inlet groove barrel, and communicating holes distributed in an array are formed in the water seal groove barrel. According to the emergency water drainage device, the emergency water drainage device is arranged on the floating disc so that the situation that when water on the floating disc cannot be drained in time, the floating disc is pressed and collapsed, and then a series safety production accident is caused can be prevented, and the safety of oil storage is facilitated; and the indicating piece is arranged so that a worker can know the water level in the water seal groove barrel in time, and then the water can be added in time, so that the situation that oil wax is generated at the water seal groove barrel and the connecting pipe body due to the fact that oil enters the water seal groove barrel is prevented, volatilization loss of the oil is reduced, and normal proceeding of emergency water drainage is ensured.

Description

technical field [0001] The invention relates to a drainage device, in particular to a water level indicating emergency drainage device. Background technique [0002] The tank roof of the external floating roof oil tank is directly exposed to the atmosphere, and the accumulated water and debris collected on the floating roof will affect the safety of the floating roof. For this reason, a central drainage system will be installed. The current central drainage systems of external floating roof oil tanks are roughly divided into two categories, one is rigid drainage system and the other is flexible drainage system. Normally, rainwater is drained out of the tank through the central drain. However, when the central drainage pipe is blocked or oil leaks and cannot be used, the accumulated water on the floating roof cannot be discharged; in addition, due to the heavy rainfall, the drainage capacity of the central drainage pipe is limited, and the accumulated water cannot be dischar...

AI Technical Summary

Problems solved by technology

However, when the central drainage pipe is blocked or the oil leaks and cannot be used, the accumulated water on the floating roof cannot be discharged; in addition, due to the heavy rainfall, the drainage capacity of the central drainage pipe is limited and the accumulated water cannot be discharged in time

The above situation will lead to poor drainage effect

Therefore, it is necessary to design an emergency drainage device. In the emergency drainage device of the prior art, the water level in the water-sealed tank cannot be displayed. It was found that the grease would enter the water seal tank and the connecting pipe, and the grease would volatilize, causing the oil to be lost. The grease entering the water seal tank would cause the water seal tank and the connecting pipe to generate oil wax, resulting in blockage and a reduction in pipe diameter.
