Having heavy stand, ratchet is fixed screw by ratchet and is arranged on drivewheel, and the heavy stand of drivewheel and ratchet are separately installed with pin,
Spring steel plate is arranged on ratchet and fixes between screw and pin, and spring steel plate makes ratchet keep connecing with the surface of the ratchet of gear
Touch；In the endoporus of end cap, interference is provided with right lining, is provided with right back-up ring in the counterbore of cover internal, and end cap passes through trip bolt
It is arranged on the right side of gear.Above-mentioned ratchet transmission structures is more complicated, and can only realize single-direction transmission.
Booth is affected, in canopy by the factor such as soil and temperature in indoor and outdoor temperature, illumination, wind-force, wind direction and canopy
Temperature Change is relatively big, and therefore, the mouth that leaks informaton of booth needs frequent opening and closing, to reach shed vegetable growing environment
Regulation, adapts to the growth of vegetable.In the prior art, booth leak informaton mouth typically use fixed pulley and revolution pulley combination side
Formula, changes the draw direction with rope, controls the motion forward or backwards of output shaft, drives rope to pull the film that leaks informaton, it is achieved to put
The opening and closing in air port.But, the two ends of the technology usually rope used at present are directly wound on output shaft, due to rope
The thickness of Suo Benshen, such rope is at one end wound around during one end loosens, and the linear velocity of rope ends is different, rope this
Body is disputed the most uneven, the imbalance that the mouth that causes leaking informaton opens and closes.
Summary of the invention
For the defect of unidirectional transmission in prior art, the present invention provides the unidirectional biography of a kind of mouth that leaks informaton for booth
Dynamic device, this unidirectional transmission makes full use of the construction features of ratchet and pawl, it is achieved utilize a set of power set and a set of
Drive mechanism can be achieved with Bidirectional driving, has both remained ratchet, the advantage of ratchet unidirectional delivery, again can bi-directional power.
In order to overcome booth in prior art to leak informaton the defect of mouthful unidirectional transmission, the technical solution used in the present invention
For a kind of unidirectional transmission, described unidirectional transmission include power set, power transmission shaft, the first ratchet, the second ratchet, the
One ratchet, the second ratchet, the first driven pulley and the second driven pulley, power set are connected to transmit power with power transmission shaft, and first
Driven pulley and the second driven pulley can be rotatably set on power transmission shaft, described first ratchet, the second ratchet, the first driven pulley and
Two driven pulleys position that arranges on power transmission shaft is followed successively by: first driven pulley the-the first ratchet the-the second ratchet the-the second driven pulley, institute
Stating the first ratchet to be arranged on the circumference of the first driven pulley, the second ratchet is arranged on the circumference of the second driven pulley, and described first
Ratchet and the second ratchet are fixed with power transmission shaft and are connected, and the first ratchet and the second ratchet are provided with hook tooth, and hook tooth is with described
First ratchet, the second click-fit so that when power transmission shaft rotates forward or backwards, one of the first driven pulley and the second driven pulley with
Drive axis.
Described first ratchet is arranged on the circumference of the first driven pulley, and the first ratchet and the first driven pulley are with the first bearing pin even
Connecing, the first ratchet can rotate around the first bearing pin, and the first bearing pin between the first ratchet and the first driven pulley is provided with the
