Abstract
The invention discloses a descent control device which can allow people to descend so as to escape from a high building and can generate power. The descent control device comprises a shell, a permanent magnet generator, a speed-increase gearbox, a chain wheel, a chain and a lamp bulb. The permanent magnet generator comprises a machine shell, a permanent magnet stator, an armature rotor and electric brushes. The permanent magnet stator is connected with the interior of the machine shell. The armature rotor penetrates through an inner hole of the permanent magnet stator to be movably connected with the machine shell. The two electric brushes are arranged on the machine shell to make contact with two slide rings on an armature rotor shaft. The permanent magnet generator and the speed-increase gearbox are arranged in the shell. The permanent magnet stator of the generator is provided with eight pairs of magnetic poles. A small air gap 0.2 mm wide is formed between the permanent magnet stator and the armature rotor. The speed-increase gearbox is composed of multiple stages of rubber gears. The speed ratio of the speed-increase gearbox is larger than 50. One side shaft of the speed-increase gearbox is connected with the permanent magnet generator through a shaft. The other side shaft of the speed-increase gearbox is connected with the chain wheel. The chain wraps the chain wheel. The high-power lamp bulk with the power of 300 watts or higher is connected with the lower face of the shell. The lamp bulb is electrically connected with the permanent magnet generator. By means of the descent control device capable of generating power, the descending potential energy of people can be converted into electric energy to light up the lamp bulb, and the downwards-sliding speed of people can be decreased; the descent control device has the advantages of being free of mechanical abrasion, safe and reliable to use, low in noise and the like.
Description
Technical field
The present invention relates to the descending lifeline that can generate electricity that a kind of people declines from high-rise life saving.
Background technology
Current known CN103956031A title is applied to the induction warning device of escaping descent control device limit using state, it is made up of magnet, coil, rectification circuit, voltage-regulating circuit, warning circuit, the rotating mechanism of existing escaping descent control device speed regulator is equipped with magnet, coil, rectified current, voltage-regulating circuit warning circuit be contained on governor housing respectively.It utilize magnet rotation magnetic force Linear cut coil-induced go out electric current through being rectified into direct current, go to promote alarm action, play forewarning function, prevent the harm that the malfunctioning decrease speed of descending lifeline is brought too soon.Because said mechanism does not have iron core.Coil-induced electricity is very little, can not produce armature-reaction, the effect just not stoping people to decline., there is mechanical friction and worn and torn and feel unwell complete, also have noise in the escaping descent control device of existing mechanical damping mechanism.
Summary of the invention
In order to overcome mechanical easy to wear, the deficiency that is complete, that have noise of feeling unwell of existing escaping descent control device existence, object of the present invention provides a kind of the descending lifeline that can generate electricity that use is reliable, nothing is worn and torn, noise is little.
The present invention's adopted technical scheme of dealing with problems is: it comprises shell, magneto, gearbox, sprocket wheel, chain, bulb, generator comprises casing, permanent-magnet stator, armature rotor, brush, 16 pole magneto generators and gearbox are housed in the enclosure, 0.2mm small air gap is provided with between permanent-magnet stator and armature rotor, gearbox is taken turns by multistage rubber teeth and is formed, speed ratio is greater than 50, gearbox one side shaft is connected with permanent magnet generator arbor, another side shaft of gearbox connects a sprocket wheel, chain wraps on sprocket wheel, more than 300 watts bulbs are connected below shell, bulb and permanent magnet generator mechatronics.When people holds chain, the weight zone of action movable sprocket of people rotates, drive electrical generators fast rotational is accelerated through gearbox, the generator armature rotor coil cutting permanent-magnet stator magnetic line of force induces alternating current and goes to light bulb, armature field can be produced at armature rotor simultaneously, the direction in this magnetic field is contrary with permanent-magnet stator main field direction, these two kinds of direction opposite magnetic fields interact, armature rotor can be stoped to rotate, thus reduce people's decrease speed, this drag size and output generator current size and gearbox speed ratio size proportional, be inversely proportional to size of gaps.Because this generator adopts 8 pairs of magnetic poles, frequency and voltage is just high, adopt 0.2mm small air gap magnetic resistance little, generating efficiency is high, and resistance is large, again because not having mechanical damping mechanism, mechanical is worn and torn, use with regard to safety, gear of speed increasing box selects elastomeric material to make, noise is little, thus reach the present invention have use reliable, without the little object of wearing and tearing noise.
The invention has the beneficial effects as follows have and use reliable, little without wearing and tearing, noise, can also throw light on.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Figure is the profilograph of the embodiment of the present invention.
In figure 1, shell 2, magneto 2-1, casing 2-2, permanent-magnet stator 2-3, armature rotor 2-4, brush 3, gearbox 4, sprocket wheel 5, chain 6, bulb
Detailed description of the invention
In the embodiment shown in figure, suspension ring are established on shell 1, connect more than 300 watts big bulbs 6 below, shell 1 is built with 16 pole magneto generators 2 and gearbox 3, magneto 2 connects permanent-magnet stator 2-2 by casing 2-1, armature rotor 2-3 is flexibly connected with casing 2-1 through permanent-magnet stator 2-2 endoporus, and two brush 2-4 are contained in casing 2-1 contacts with two slip rings on armature rotor 2-3 axle and form together.The permanent-magnet stator 2-2 of magneto 2 has 8 pairs of magnetic poles, and have 0.2mm small air gap between permanent-magnet stator 2-2 and armature rotor 2-3, make generator send voltage high, electric current is large.Armature-reaction is also large, and under stoping people, slip resistance is also large.Gearbox 3 is taken turns by multistage rubber teeth and is formed, and speed ratio is just large, and rubber gear noise is little, and gearbox 3 side output shaft is connected with magneto 2 axle, and opposite side power shaft connects a sprocket wheel 4, and chain 5 wraps on sprocket wheel 4.When people declines, movable sprocket 4 slow rotation is with by chain 5, make magneto 2 1000 revs/min of rotations by the gearbox 3 of 50 times of speed ratios, the high-tension electricity sent goes to light more than 300 watts bulbs 6, now armature rotor 2-3 has electric current to pass through to produce the armature field contrary with main field, two kinds of direction opposite magnetic fields act in air gap, the rotating speed of armature rotor 2-3 can be reduced, play people to decline reduction of speed effect, reduction of speed effect size and size of current and gearbox 3 speed ratio size proportional, with size of gaps inversely, decrease speed speed can adjust bulb 6 watt level.The large decline of power is slow, contrary just fast.It is high that this device adopts 8 pairs of magnetic poles and 0.2mm small air gap to have generating efficiency, and output current is large, and resistance is just large.Because not having mechanical damping mechanism, machinery is wearing and tearing not, and safe and reliable rubber gear noise is little.
