[0003] However, the existing fire pumps lack a structure that can adapt to wide working conditions, which makes it impossible for the fire pumps to adjust according to the water volume. When the fire protection system switches back and forth between small flow and high pressure or large flow and low pressure, the motor will be overloaded and unable to adapt to complex and changing fire protection scenarios.

[0037] The use method and advantages of the present invention: A full-flow non-overload fire pump, the working process is as follows:

[0038] When it is necessary to extinguish a fire, the pump 1 is started. The card wheel 306 in the housing 301 is pushed by the force of the short spring rod 1202, and the card wheel 306 and the locking plate 305 are kept in a locked state. The shaft of the pump 1 directly drives the turbine 304 connected to the locking plate 305 to rotate, and the upper rotating tooth 405 engaged with the bottom of the upper card tooth 403 drives the planetary gear 409 to rotate. During the rotation, the planetary rod 4010 rotates the satellite gear 4012 and the internal sun gear 4013 through the planetary tripod 4011, thereby increasing the rotation speed in the initial stage and quickly drawing water from one end of the water inlet pipe 11 into the inducer 704 in the water upper cylinder 701. As the upper shaft 703 on the side of the bottom of the sun gear 4013 rotates, the water also rotates along the lower screen 802 at the bottom of the sleeve 6 through the impeller 807, allowing the water to flow out of the water outlet pipe 10.

[0039] Then, when the water flow continues to increase, it is the shaft of the pump 1 that pushes it at first. As the water flow gradually increases, the inertia brought by the water pumping increases the force applied to the impeller 807, further increasing the rotation speed of the lower shaft 803 and the upper shaft 703. At this time, the increase in the amount of water pumped increases the pressure inside the water inlet pipe 11, thereby lifting the perforated slot rod 1209 in the arc frame 1208. The rising perforated slot rod 1209 pushes the lower jacket 408 and the upper jacket 404 to rise, and the lower latching teeth 407 and the upper latching teeth 403 also rise together, wherein the lower latching teeth 407 and the lower rotating teeth 406 The bottom side is engaged, and after the upper latching tooth 403 disengages from the upper rotating tooth 405, the lower rotating tooth 406 starts to drive the planetary gear carrier 4014 to rotate, and then the sun gear 4013 rotates through the satellite gear 4012. At the same time, the rising upper jacket 404 is squeezed down by the short winding rod 1203 and the fork rod 1204 by the lifting rod 1206, so that the latch wheel 306 is disengaged from the locking plate 305. After disengagement, the turbine 304 is driven to rotate by the liquid inside the housing 301 when the pump impeller 302 rotates. The liquid inside the housing 301 is then returned to the pump impeller 302 through the guide wheel 303.

[0040] Finally, through the automatic switching of the linkage structure, the overload of the pump 1 and the corresponding changes in the water pressure caused by different water flows are avoided. The impeller 807 located in the lower water cylinder 801 is impacted by the continuously increasing water flow, and the water flow pushes the impeller 807 and the slide bar 8010 to slide along the turn plate 805. When the slide bar 8010 moves to the other end of the arc of the turn plate 805, the movable bracket 806 located on the side of the turn plate 805 stretches the tension spring 808 between the fixed bracket 809, and the opened impeller 807 forms different opening angles to facilitate the passage of water and reduce the durability loss of the impeller 807. When the impact is reduced, the turn plate 805 is pulled back by the tension spring 808 to achieve an adaptive structure.
