A remote control self-sealing liquid inhalation device

Abstract

A remote-controlled self-styled liquid suction device, comprising an elbow seat, a straight pipe connected to the lower end of the elbow seat, and a hose joint installed on the upper end of the elbow seat; there is a liquid inlet at the lower part of the straight pipe, and a suction pump Bottom valve device that opens the liquid inlet when starting and closes the liquid inlet when the suction pump stops; there is a liquid level sensor on the inner wall of the straight pipe above the liquid inlet; there is an installation box on the elbow seat; there are remote control launch boards, power There is a wireless transmitting module on the remote control transmitting board; the outer wall of the installation box has a power button for controlling the power switch, a start control button for controlling the start of the wireless transmitting module, and a stop control button for controlling the stop of the wireless transmitting module; The wire is connected with the remote control transmitting board; a remote control receiving control device is also included. The invention facilitates the real-time operation of liquid suction, and has the function of self-sealing to prevent liquid backflow, which not only avoids the generation of a large number of air bubbles due to air suction, but also prevents the suction pump from being damaged due to cavitation.

Description

technical field [0001] The invention relates to a remote-controlled liquid suction device, in particular to a liquid suction device capable of transmitting remote control signals wirelessly and having a self-sealing function. Background technique [0002] In the event of a fire, especially a large petrochemical fire, it is necessary to provide enough fire-fighting foam stock solution to the fire truck to achieve the purpose of extinguishing the fire. The characteristic of the fire-fighting foam stock solution is that it will produce a lot of bubbles after mixing with water or air. The normal situation is to stir and mix with water and air through a fire engine to produce a large amount of foam for fire extinguishing; while the foam stock solution must not have foam before entering the fire engine, otherwise it will directly affect the fire extinguishing effect. [0003] At present, most fire-fighting foam solutions are stored in barrels (200L / barrel). How to quickly and con...

Problems solved by technology

When the connecting pipeline sucks the liquid level in the small container lower than the air inlet of the suction pipe, the air enters the sealing cavity of the self-sealing block through the air inlet pipe, and the operating device bounces back to the sealing state to realize the self-sealing function, but the main problems are After the suction device is closed, the suction pump stop signal cannot be sent, causing the suction pump to be damaged prematurely due to frequent cavitation
