Abstract
The utility model discloses an electromagnetic damping type slowly descending device, which comprises a power generator, a transmission and a winch. The electromagnetic damping type slowly descending device is characterized in that a shaft of the power generator is connected with the transmission and the winch to form a whole, wherein the power generator is driven by the winch and the transmission to rotate to produce a voltage; and a current is formed through external impedance. Meanwhile, due to the current, a rotor of the power generator is affected by electromagnetic damping. Through changing load impedance and changing the rotating speed of the power generator, an appropriate safe descending speed is reached.
Description
Technical field
The utility model relates to and comprises above-mentioned electric-control system, speed change system and transmission system, particularly relates to a kind of electromagnetic damping formula slow descending device that is used to escape.
Background technology
On the basis of the deficiency of seeing existing building fire escape device, designed an ability and the more escaping device from fire disaster of more options-electromagnetic damping formula slow descending device is provided for the survivor.Said works are according to the electromagnetic damping effect, are main with manual adjustments at present.Machine can be regulated decrease speed automatically under the Utopian situation, and the people can be fallen in the velocity interval of safety.Can be widely used in all kinds of public places at home, easy to use.
The utility model content
The utility model method of operating is simple, does not need professional's auxiliary operation and maintenance, can stop arbitrarily in use or rising by a small margin, does not rely on other energy, adopts the method for electromagnetic damping to slow down, and reliability is high.This equipment not only can be applicable to fire rescue, can also be widely used in occasions such as downhole rescuing, mountain-climbing climbing rescue.
The utility model is achieved in that
A kind of electromagnetic damping formula slow descending device is used to control decrease speed comprising an electric-control system, and a speed change system is used for the rotating speed between regulator generator and the capstan winch; A dynamical system comprises generator and capstan winch, it is characterized in that the axle of the generator in the described dynamical system, links to each other with speed changer and capstan winch; Become as a whole, described capstan winch, speed changer drive the generator rotation and produce voltage, form electric current through external impedance; Electric current makes generator amature receive the electromagnetic damping effect; Change load impedance, change generator speed, reach safe decrease speed.
The utility model provides very big help for solving the high-rise fire rescue, can increase high-rise disaster escape chance, thereby reduce the injury of disaster to personnel.Simplicity of design, processing ease not only is applied to fire rescue and can also be applied to occasions such as downhole rescuing, mountain-climbing climbing rescue.The scope of application is extensive, and cost is low, and suitable company, general family popularize.
Description of drawings
Fig. 1, Fig. 2 are the installation diagrams of the utility model patent
Fig. 3 is the circuit diagram of the utility model patent
Below in conjunction with accompanying drawing to the utility model further explain.
The specific embodiment
The core branch art of the utility model electromagnetic damping formula slow descending device is to utilize the principle of generator; When the generator output end impedance hour; Electric current is bigger, and damping action is stronger, and the rotating speed of capstan winch is less; Promptly through changing the size of load impedance, the velocity of rotation of control generator is utilized the principle of generator.For making those skilled in the art person can better understand the utility model scheme.Below in conjunction with concrete real-time mode the utility model is done further to specify.Please refer to Fig. 1, Fig. 2, Fig. 3.The utility model is connected together with capstan winch 1 through axle and speed changer 2 by generator 3 in the said transmission system and constitutes transmission system; In a kind of specific embodiment; Said electric-control system repeat circuit 4 and gauge tap 7 are attached to framework 5; Change the rotating speed of the size control generator 3 of electric currents through regulation control switch 7, slide rail 6 upper ends connect the body of wall lower end and are connected with framework 5, when escape rope need use, outwards release.Described generator 3 output end voltages are directly proportional with generator 3 rotating speeds, and monitoring generator 3 output end voltages can obtain generator speed information, obtain the velocity information that escape rope descends, and come the regulating circuit impedance to obtain safe sinking speed.
