Problems solved by technology

[0002] There are many fire accidents every year, but many fire accidents can be handled properly to minimize the loss. The fire control cabinet of the current fire pump room does not have the fire emergency start function inside, because the environment of the fire control cabinet is relatively It is dark and humid. In this environment, the auxiliary components in the fire control cabinet are corroded and rusted for a long time, which leads to the failure of the secondary circuit. As a result, the fire pump cannot be started during fire fighting, and there is no water in the fire hydrant. Even if there are fire fighting equipment , People can't realize self-rescue in the first time, which brings unnecessary economic losses and casualties. After adopting the fire emergency starting device, when the secondary circuit of the fire control cabinet cannot start the fire pump, start using the fire mechanical emergency starting device, the panel Rotate the handle 90°, the push rod pushes the AC contactor forward, connects the three-phase current, starts the fire pump, and people can extinguish the fire by themselves to reduce losses

Embodiment 1

[0039] Because most of the fire control cabinets are in a dark and humid environment, in this environment, the auxiliary components in the fire control cabinet are corroded and rusted for a long time, resulting in the failure of the secondary circuit and the inability to start the fire pump in the event of a fire. We can use the fire-fighting machinery emergency starting device, first rotate the handle 1 by 90°, and then turn the lever 2 by 90°. Since the center of the rotating block 40 is provided with a rectangular hole 40-2, the bottom is perpendicular to the rotating block 40. There are two threaded holes 40-3 on the axis and at an angle of 90°. The rotating block 40 is connected to the rotating rod 2 through a rectangular hole 40-2 provided on it, and then the rotating block 40 is connected to the rotating block 40 through bolts 41. The rods 2 are tightened, so the rotating block 40 also rotates 90°, and because the upper end of the rotating block 40 is provided with an en...

Embodiment 2

[0041] We artificially twist the screw sleeve 50 by hand. Since the screw sleeve 50 is connected with the screw shaft 51, and the screw shaft 51 has a rectangular cross-section, the center of the worm 52 is provided with a rectangular hole 2 along the axis direction. The shaft 51 passes through the rectangular hole two on the worm 52, and then the screw sleeve 50 drives the worm 52 to rotate through the screw shaft 51, and then because the worm 52 meshes with the worm gear 53-1 on the double gear 53, the double gear 53 The upper gear 53-2 meshes with the rack 54. Since the end of the rack 54 is provided with an ear tube 54-1, the ear tube 54-1 is set in the long slot hole 45, and the ejector rod 55 passes through it. Through the ear tube 54-1 on the rack 54, it is realized that the ejector rod 55 moves along the long slot 45 with the drive of the rack 54, and two long slots 45 are provided on the lifting platform 43, Slide rails 46 are respectively provided on both sides, and ...
