Fig. 2 is the internal structure schematic diagram of fire-fighting well-bucket dewatering outlet switch controlling device;
Fig. 3 is locked out state connecting rod position schematic diagram;
When Fig. 4 is carried out electric motor starting, rocking arm moves upward schematic diagram;
Fig. 5 is that the plug of central steel cord moves downward schematic diagram;
Fig. 6 is that the plug of central steel cord moves upward schematic diagram.
Detailed description of the invention
In order to be more clearly understood from the technical characteristic of the present invention, purpose and effect, now comparison accompanying drawing is detailed Describe the detailed description of the invention of the bright present invention in detail.
As shown in Figure 1 and Figure 2, fire-fighting well-bucket dewatering outlet of the present invention switch controlling device includes housing 1 and peace Motor 6, rocking arm 7, linkage 8, slotting ear 9 and the pulley 5 being contained on housing 1.
The both sides of pulley 5 are respectively side steel wire rope 2 and central steel cord 3, side steel wire rope 2 and center Steel wire rope 3 is connected.The lower end of side steel wire rope 2 connects balancing weight 4, and the lower end of central steel cord 3 connects Controlling the flashboard of dewatering outlet opening and closing, when central steel cord 3 moves down, dewatering outlet is opened.Central steel cord 3 Being provided with plug 10, plug 10 is positioned at above slotting ear 9, inserts ear 9 and is connected with linkage 8, rocking arm 7 Blocking linkage 8, now inserting ear 9 cannot rotate down, and plug 10 can not move down, and dewatering outlet keeps Closed mode.Motor 6 drives rocking arm 7 to rotate, and linkage 8 connects back-moving spring 11, back-moving spring 11 have the restoring force making linkage 8 reset.
As shown in figures 3 to 6, when the built-in full water of fire-fighting well-bucket, central steel cord 3 is drawn by downward Power, rocking arm 7 blocks linkage 8, and slotting ear 9 cannot rotate slotting ear 9 and keep off below plug 10, discharges water Mouth remains off.When motor 6 band motion rocker arm 7 rotates, rocking arm 7 separates with linkage 8, inserts Ear 9 rotates down, it is impossible to block plug 10, and plug 10 moves down, and dewatering outlet is opened, and linkage 8 exists Reset under the effect of back-moving spring 11.
After discharging water, central steel cord 3 not having the gravity of water, connect on side steel wire rope 2 joins Under the action of gravity of pouring weight 4, rotating around pulley 5, central steel cord 3 be pulled upwardly, plug 10 moves Move and reset above slotting ear 9.
Further, linkage 8 include first connecting rod 801, second connecting rod 802, third connecting rod 803, Fourth link 804 and the 5th connecting rod 805.First connecting rod 801 is arranged on housing 1 by the first rotating shaft 806 On, third connecting rod 803 is arranged on housing 1 by the second rotating shaft 807, and the 5th connecting rod 805 is by the 3rd Rotating shaft 808 is arranged on housing 1, and one end of second connecting rod 802 is hinged with first connecting rod 801, the other end Hinged with third connecting rod 803 and fourth link 804, fourth link 804 is hinged with the 5th connecting rod 805, inserts Ear 9 is also mounted in the 3rd rotating shaft 808.Back-moving spring 11 is torsion spring, is separately mounted to the second rotating shaft 807 With in the 3rd rotating shaft 808.The lower section of rocking arm 7 is provided with spacer pin, to rocking arm 7 carry out spacing.Motor 6 It not directly to be connected with the gate of dewatering outlet, but by rocking arm 7, linkage 8, slotting ear 9, counterweight Block 4 parts such as grade realize the opening and closing of dewatering outlet, reduce the stress of motor 6, and motor 6 operating current is little, utilize The gravity of balancing weight 4 makes control device automatically reset, it is achieved automatic blocking after discharging water, and automaticity is high, Save manpower.
Further, the upper end of plug 10 is pointed nose, and the lower end inserting ear 9 is inclined-plane, and plug 10 moves Time, pointed nose and contact of incline plane, can upwards push up slotting ear 9, reduce resistance.
Above in conjunction with accompanying drawing, embodiments of the invention are described, but the invention is not limited in above-mentioned Detailed description of the invention, above-mentioned detailed description of the invention is only schematic rather than restrictive, this The those of ordinary skill in field, under the enlightenment of the present invention, is being protected without departing from present inventive concept and claim Under the ambit protected, it may also be made that a lot of form, within these belong to the protection of the present invention.
