Before using this device, the feed liquor pipe on the plunger pump head 12 is communicated with the water source, the drain pipe of the plunger pump head 12 is communicated with the external pipeline, when using this device to supply water for fire-fighting work, the staff starts the double-shaft motor 14, the first output shaft 15 and the second output shaft 151 of the double-shaft motor 14 are all rotated anticlockwise (from top to bottom direction), the first output shaft 15 drives the rotation shaft 17 to rotate through the transmission piece 16, the rotation shaft 17 drives the piston inside the plunger pump head 12, and the fire-fighting work is supplied water through the piston sliding.
While the biaxial motor 14 is started, the second output shaft 151 drives the cooling fan 4 to rotate simultaneously, the cooling fan 4 rotates counterclockwise (from top to bottom), the cooling fan 4 sucks air from the circumferentially distributed air inlet holes 42, then moves downward through the holes on the second fixing shell 41 to pass through the biaxial motor 14, cools the biaxial motor 14, then discharges the air outwards through the second air outlet holes 45 and the first air outlet holes 44 (initially, the second air outlet holes 45 are aligned with the adjacent first air outlet holes 44), cools the biaxial motor 14, and prevents the biaxial motor 14 from overheating.
When the position of installing this device is water intaking, the liquid level from the top down is beyond this device gradually, after the liquid level is beyond floating plate 34, two floating plates 34 are upwards moved gradually under the effect of buoyancy, floating plate 34 drives the second stopper 33 on it and upwards moves, take the second stopper 33 on the right side as an example, second stopper 33 is through the first stopper 31 of inclined plane extrusion in the in-process of upwards moving, make first stopper 31 left movement, first stopper 31 compresses first spring 32, the process of first stopper 31 left movement breaks away from with first fixed block 3 gradually, after first stopper 31 breaks away from the contact with first fixed block 3, two extension springs 22 drive seal shell 21 upwards move (initially, two extension springs 22 are the power state).
In the process of upward movement of the sealing shell 21, the first air outlet hole 44 and the adjacent second air outlet hole 45 are mutually far away and sealed, meanwhile, the sealing shell 21 drives the upper end of the first telescopic pipe 5 and the miniature water pump 62 to move upwards, the first telescopic pipe 5 is stretched, the miniature water pump 62 drives the upper end of the second telescopic pipe 61 to move upwards, the second telescopic pipe 61 is stretched, the miniature water pump 62 drives the upper end of the adjacent third telescopic pipe 63 to move upwards through a circular pipe, the third telescopic pipe 63 is stretched, the sealing shell 21 gradually contacts with the isolating ring 43 in the upward movement process and presses the isolating ring 43 upwards, so that the isolating ring 43 ascends, at the moment, the upper end of the first telescopic pipe 5 is communicated with a hole on the isolating ring 43, the circumferentially distributed air inlet holes 42 are gradually blocked in the upward movement process of the isolating ring 43, water is prevented from entering, the upper side surface of the isolating ring 43, which moves upwards, is not moved after being contacted with the shell 11, and at the moment, the circumferentially distributed air inlet holes 42 are completely blocked by the isolating ring 43.
In the process that the sealing shell 21 drives the micro water pump 62 to move upwards, the rubber wheel at the upper end of the micro water pump 62 is gradually contacted with the rubber wheel at the upper end of the double-shaft motor 14, meanwhile, the rubber ring on the sealing shell 21 is contacted with the ventilation shell 11, the sealing shell 21 and the ventilation shell 11 are further sealed, after the sealing shell 21 stops, the rubber wheel at the upper side of the micro water pump 62 is completely contacted with the rubber wheel at the upper side of the double-shaft motor 14, and at the moment, the double-shaft motor 14 is completely wrapped through the ventilation shell 11 and the sealing shell 21, so that the water inlet of the double-shaft motor 14 is prevented from being unusable.
Because the lower side surfaces of the water inlet pipe 6 and the water outlet pipe 64 are positioned below the floating plate 34, when the water surface passes through the floating plate 34 and also passes through the lower ends of the water inlet pipe 6 and the water outlet pipe 64, if the double-shaft motor 14 is started at the moment, the rotating shaft above the double-shaft motor 14 drives the rubber wheel on the double-shaft motor to rotate, the rubber wheel at the upper end of the double-shaft motor 14 drives the rubber wheel on the micro water pump 62 to rotate, and then the transmission shaft of the micro water pump 62 rotates, water is sucked into the adjacent second telescopic pipe 61, gradually enters the adjacent second telescopic pipe 61 upwards from the water inlet pipe 6, cools the double-shaft motor 14 through the water in the second telescopic pipe 61, then enters the adjacent third telescopic pipe 63 through the miniature water pump 62, moves downwards in the third telescopic pipe 63, cools the double-shaft motor 14, and finally is discharged from the adjacent water discharge pipe 64 to form a circulation.
In the process of the operation of the double-shaft motor 14, the cooling fan 4 rotates synchronously, at this time, the air in the ventilation shell 11 flows downwards from the upper part of the second fixed shell 41 under the action of the cooling fan 4 and enters the hole below the first telescopic pipe 5, and then is discharged from the upper part of the first telescopic pipe 5 and enters the second fixed shell 41, so that circulation is formed, heat exchange between the double-shaft motor 14 and water is accelerated, the double-shaft motor 14 is prevented from overheating, and after the double-shaft motor 14 is used, the double-shaft motor 14 is closed.
When the water surface descends, the staff checks the device and resets the device.
The use frequency of the fire pump is closely related to the frequency of fire, in daily life, the fire pump is in a state of almost not being used, in the long-time placing process, because the lubricating oil of the upper rotating shaft part of the fire pump is only thin and one layer, the lubricating oil is easy to oxidize by oxygen in the air, so that the lubricating effect is lost, the existing rotating shaft part of the fire pump generally uses mechanical sealing, the sealing is carried out through the mutual rotation of a movable ring and a static ring, an oil film exists between the movable ring and the static ring and plays an important role in sealing, if the lubricating effect of the lubricating oil is lost, the rotating resistance of the rotating shaft of the fire pump is increased, and if the lubricating oil loses the lubricating effect, the fire pump is damaged, and the fire water cannot be provided for fire fighters, therefore, the invention improves through the following steps:
