Vehicle-mounted large-capacity water tank

Abstract

A vehicle-mounted large-capacity water tank comprises a water tank body, a water inlet, a water outlet, an overflowing opening and a liquid level valve. The water inlet and the overflowing opening are formed in the top face of the water tank body, and the liquid valve is arranged in the water tank body. The vehicle-mounted large-capacity water tank is characterized in that the water tank further comprises a self-priming centrifugal pump which is fixed to the top face of the water tank body; a water inlet of the self-priming centrifugal pump is formed in the lower portion inside the water tank body; and an water outlet of the self-priming centrifugal pump is a water outlet of the water tank. The water tank can be arranged at the bottom of a train or arranged inside a train body and is lower than the gravity center of the train, so that the safety coefficient is high.

Description

technical field [0001] The invention relates to a water tank, in particular to a vehicle-mounted large-capacity water tank. Background technique [0002] On a railway freight car or an alpine running car, a large-capacity water tank is required due to long-distance transportation. Considering that some trains may run in alpine areas, and the road conditions are relatively bumpy, and the weight of the large water tank and the weight of the internal water have a large cumulative inertia, the traditional water tank has the following defects: [0003] (1) The traditional water tanks are set on the top of the train or in a high position inside the carriage. The water inlet is higher than the water outlet, and the position of the water tank is higher than the center of gravity of the train, which is not good for the stability of the train. [0004] (2) The traditional water tank cannot effectively prevent the cold, and the freezing and solidifying volume of the water in the car w...

AI Technical Summary

Problems solved by technology

[0003] (1) Traditional water tanks are installed on the top of the train or at a high position inside the carriage, where the water inlet is higher than the water outlet, and the position of the water tank is higher than the center of gravity of the train, which is not good for the stability of the train operation

[0004] (2) The traditional water tank cannot effectively prevent the cold. The water in the car freezes and solidifies and the volume increases, which will break the water tank, and the frozen water tank cannot continue to supply water

[0005] (3) The water in the traditional water tank will have a great impact due to inertial impact, which will not only cause damage to the side wall structure of the water tank, but also have a great impact on the fixing seat

Once the fixing device fails, it is very dangerous

[0006] (4) The liquid level of the traditional water tank is invisible, and it is impossible to observe the water level in the water tank

[0007] (5) Does not have automatic water replenishment function

[0008] (6) The water source needs to have a certain pressure when supplying water, and it does not have a self-priming function. If the air in the pipeline cannot be pumped out, it cannot rely on the traditional siphon effect to supply water

[0009] (7) The traditional water tank cannot enter the interior for maintenance, and once damaged, the water tank can only be replaced
