Abstract

The invention relates to the technical field of electric power transmission, in particular to a power adapter, comprising a roller for storing cables. A first wire storage tray is fixed arranged on the rotary shaft of the roller; a bushing matching with the gap of the rotary shaft is arranged at one side of the first wire storage tray close to the roller; ratchet wheels are respectively fixed at two ends of the bushing; a second wire storage tray is arranged between the ratchet wheel and the roller; the second wire storage tray is matched with the gap of the rotary shaft and fixed on a support frame; pawls are arranged on the first wire storage tray and the second wire storage tray; a guide wheel bracket is arranged on the bushing; a guide wheel capable of rotating around the axis is arranged at the upper part of the guide wheel bracket; and the axis of the guide wheel is perpendicular to the rotary shaft. A friction plate is arranged between the guide wheel bracket and the bushing. A balance weight is arranged on the guide wheel bracket at the other side of the rotary shaft. According to the power adapter, the electrical switchover with a bigger rotating angle between a rotational cable and a fixed cable can be realized, is in a non-contact mode and can be used for continuous switch-on.

Description

Electric commutator
Technical field
The present invention relates to power transmission technical field, especially a kind of electric commutator.
Background technology
The simplest electric commutator is no more than patch panel and connector assembly, but these simple electric commutators may be only available for fixing electrical equipment The connection of the electricity between parts.For the switching between two parts having relative motion, patch panel and connector assembly etc by no means Electric commutator can be done by.The most in succession occur in that spiral adapter, slip ring are complex with what contact formed, for Adapter known to people.The connection of the electricity that this kind of adapter is capable of between two relative movement parts, therefore, obtains wide Weary application.But these electric commutators also expose some self weakness in the use of some occasions, such as: spiral The relative rotation that adapter is only applicable between rotatable parts and fixed component is less than the occasion of 360 ° of degree;Slip ring and contact composition Adapter, owing to there is contact resistance and easily causing frictional sparking, is not often suitable for transmitting the small and weak signal of telecommunication and not allowing It is used in the occasion that electric noise occurs due to sparking, is not more suitable for marine environmental conditions.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric commutator, it is possible to realize between stationary parts with moving component relative The transmission of the signal of telecommunication that corner is bigger.
In order to solve above-mentioned technical problem, the present invention includes the cylinder for storing cable, the gyroaxis of described cylinder is fixed setting Being equipped with the first storage drum, described first storage drum is provided with and the sleeve of gyroaxis matched in clearance near cylinder side, described sleeve Two ends be fixedly installed the first ratchet and the second ratchet respectively, be additionally provided with the second storage drum between described second ratchet and cylinder, Described second stores drum and gyroaxis matched in clearance and is fixed on bracing frame, and described first storage drum and the second storage drum are near spine The end face of wheel is respectively arranged with the first ratchet and the second ratchet mated with ratchet, and described sleeve is provided with wheel bracket, described The top of wheel bracket is provided with the guide wheel being rotated about axis, and the axis of described guide wheel is vertical with gyroaxis.
It is provided with friction plate between described wheel bracket and sleeve.
Described wheel bracket is located at turn around axle opposite side and is additionally provided with balancing weight.
Present invention achieves and rotate the electricity switching that cable is bigger with fixing cable relative rotation, and be contactless, continuous print Energising.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the sectional view in figure A-A direction.
Detailed description of the invention
Embodiment cited by the present invention, is only intended to help and understands the present invention, should not be construed as the limit to scope Fixed, for those skilled in the art, without departing from the inventive concept of the premise, it is also possible to the present invention Making improvements and modifications, these improve and modification also falls in the range of the claims in the present invention protection.
As depicted in figs. 1 and 2, the present invention includes the cylinder 1 for storing cable, and the gyroaxis 2 of described cylinder 1 passes through axle Holding 21 to fix on the base 11, described gyroaxis 2 is provided with the first storage drum 3, described first storage drum 3 is near cylinder 1 Side be provided with and the sleeve 4 of gyroaxis 2 matched in clearance, the two ends of described sleeve 4 are fixedly installed the first ratchet 51 respectively With the second ratchet 52, between described second ratchet 52 and cylinder 1, be additionally provided with the second storage drum 6, described second storage drum 6 with Gyroaxis 2 matched in clearance is also fixed on bracing frame 7, and this bracing frame 7 can be the shell of electric commutator.
Described first storage drum 3 and the second storage drum 6 are respectively arranged with, near the end face of ratchet, the first ratchet 81 mated with ratchet With the second ratchet 82, when the first storage drum 3 rotates with gyroaxis 2, the first ratchet 81 on described first storage drum 3 pushes away The dynamic first equidirectional rotation of ratchet 51, when the first storage drum 3 rotates with gyroaxis 2 reverse direction, on described second storage drum 6 The second ratchet 82 prop up the second ratchet 52.
It is provided with wheel bracket 9 on described sleeve 4, is provided with friction plate 10 between described wheel bracket 9 and sleeve 4, so During pawl wheel, driving the equidirectional rotation of wheel bracket by frictional force, the size of described frictional force can be by being arranged on introduction Spring screw 92 on support 9 regulates.The top of described wheel bracket is provided with the guide wheel 91 being rotated about axis, described The axis of guide wheel 91 is vertical with gyroaxis 2.
In order to realize the wheel bracket 9 balance in rotation process, described wheel bracket 9 is located at turn around axle 2 opposite side and also sets up There is balancing weight 93.
For the ease of being further appreciated by the present invention, operation principle and process to the present invention are described further below.
In terms of A-A direction from Fig. 1, when cylinder 1 rotates clockwise, the gyroaxis 2 of cylinder 1 drives the first storage drum 3 Also rotating clockwise, rotational angular velocity is identical, is set to ω.Now, under the effect of cable 12 tensile force, wheel bracket 9 Rotating with the first storage drum 3, this is that the cable 12 on the second storage drum 6 passes through guide wheel 91 around entering the first storage drum 31.
When cylinder 1 rotates counterclockwise with ω speed, the gyroaxis 2 of cylinder 1 drives the first storage drum 3 also with the ω speed inverse time Pin rotates, and the first ratchet 81 being now fixed on the first storage drum 3 promotes the first ratchet 51 also to make counterclockwise movement.Due to There is bigger frictional force between sleeve 4 and wheel bracket 9 between two ratchets, therefore also drive wheel bracket 9 to make counterclockwise Rotate.At this moment the cable 12 that the first storage drum 3 eases out passes through guide wheel 91 around entering the second storage drum 6.
