Description

Stay-supported power generation device

Technical Field

The utility model relates to an electromechanical field especially relates to a can provide the stay-supported power generation facility of electric energy to other portable consumer.

Background

The power generation technology for providing electric energy by adopting a hand-cranking or hand-holding mode in an emergency manner is quite mature. The emergency power generation equipment with the large-size hand crank can continuously generate larger power, but the larger hand crank is inconvenient to carry. Small-size hand generating equipment or hand-held power generating equipment carry conveniently relatively, but because the volume restriction, the generating power is less usually, or because the handle is little hard and inconvenient and lead to user's tired easily.

In order to solve the problems, the hand-pulling rope is adopted to drive the generator to rotate to generate electricity, which is a potential alternative. To achieve this, the manual power generator of application No. 95244486.0 proposes an embodiment in which a hand-pulling rope is used to drive a winding drum to rotate, a volute spring is used to retract the rope on the winding drum, and a mechanism capable of unidirectional torque transmission is used to keep the generator in the same rotation direction. Similarly, a coil spring, a ratchet wheel and a winding drum with a pull wire are considered to be matched together in a plurality of patent applications, so that the aim of driving the generator to rotate in one direction is fulfilled. For example, the manual power small generator of application No. 01267953.4, the manual power multifunctional charger of application No. 03225620.5, the manual power self-generating charger of application No. 200320116825.7, the manual power generator of application No. 200620017645.7, the manual power generating device of application No. 200720058124.0, and the like.

All these designs have in common the idea of keeping the generator rotating in a single direction relatively stable. However, the disadvantages of large friction loss and easy failure and damage of the ratchet wheel or the similar one-way transmission mechanism are quite obvious. This results in greater risk of failure in emergency applications, and departs from the need for a highly reliable power supply in emergency applications.

On the other hand, with the progress of electronic technology in recent years, a technology of converting electric energy of alternating fluctuation into pulse direct current with high efficiency and storing it rapidly has become widespread, and the reliability during operation is higher than that of a mechanical transmission device. In view of the above situation, it is considered to reduce the complexity of the mechanical transmission structure as much as possible and improve the overall reliability of the emergency power generation device on the basis of using the hand-pulling cord to drive the generator to generate power.

The hand-pulling type reciprocating generator of application number 200520064197.1 provides a scheme that when a rope is pulled out, the generator can be driven to rotate, and simultaneously a coil spring and other elastic elements are tightened, and when the rope is loosened, the elastic elements drive the generator to rotate reversely and take in the rope, so that the problem of high failure risk of the unidirectional transmission mechanism is solved. However, in this solution, the elastic element is coaxial with the winding drum of the cord, the winding drum rotates for the same number of turns as the elastic element is tightened when the cord is pulled out, so that the number of turns of rotation of the winding drum and the selection of its dimensions are correspondingly limited: if a winding drum with a larger diameter is selected, the number of turns of the winding drum during the process of pulling out or taking in the wire rope can be reduced, but the whole size of the equipment cannot be reduced; if a winding drum with a smaller diameter is selected, the overall size of the device can be reduced, but the number of rotatable turns cannot be sufficiently increased due to the limitation of winding and tightening of the elastic element, so that the length of the pulled-out cord is limited, and the use is inconvenient.
