Description
Technical field
The present invention relates to a kind ofly, belong to mechanical structure field with rotation direction angle interlock regulating mechanism
Background technology
Underwater towed-body tail vane interlock is regulated, and the wind power generation blade angle of attack is regulated and propeller blade angle of attack adjusting etc., all needs the adjusting that links of angle to a plurality of tail plates or blade, and adjusting angle must equate, finally forms certain rotation direction.Present stage, each regulates target all needed independent drive for above-mentioned interlock angular adjustment, and there is following problem in this kind mode:
1 complex structure, reliability is low: each target needs individual drive, causes complex structure, and it is big to take up room.
2 controls are complicated, poor synchronization: each target independent drive, need take certain control policy, and adopt open loop control time error to accumulate easily, cause asynchronous.
Summary of the invention
The invention provides a kind ofly, can realize that individual drive is to the adjusting that links accurately of tail vane or attack angle of blade with rotation direction angle interlock regulating mechanism.
A kind ofly comprise linear electric motors, slide block, fixing screw, crank, axle sleeve, towed body afterbody shell with rotation direction angle interlock regulating mechanism, external equipment is tail vane and underwater towed-body; Wherein: slide block integral body is divided into three sections, is respectively leading portion, stage casing and back segment, and slide block leading portion and back segment are cylindrical slide shaft, the stage casing is the sliding tray section, the sliding tray section circumferentially has sliding tray one, and for ease of assembling, sliding groove wall has circumferential five equilibrium and runs through the breach of sliding groove wall; Crank is divided into head end, linkage section and end, head end and the terminal two ends that lay respectively at linkage section and vertical with linkage section, the end diameter of crank and sliding tray are little free-running fit, towed body afterbody shell is barrel-shaped housing, circumferentially having and the cooresponding axle sleeve mounting hole of the breach number of sliding groove wall of towed body afterbody shell; Its annexation is: linear electric motors are positioned on the axis of towed body afterbody shell and with the slide block leading portion captives joint, the leading portion of slide block and back segment all are equipped with axle sleeve, the axle sleeve mounting hole of the towed body afterbody shell axle sleeve of packing into, the crank front end passes axle sleeve and is positioned at outside the towed body afterbody shell, and the crank front end is captiveed joint with tail vane; Crank connecting link section and crank end are positioned at towed body afterbody enclosure, and crank end then is positioned at the sliding tray of slide block, the little gap of crank end cylindrical and sliding groove wall bearing fit has two symmetrically arranged fixing screws in the sliding tray, deviate from from sliding tray in order to prevent crank; Towed body afterbody shell is captiveed joint with the afterbody of underwater towed-body.
Rotation is equally spaced crank around the sliding tray center according to the number of tail vane.
Working process: the linear motor driving slide block is done straight-line motion, at the slide block straight-line motion simultaneously, the sliding tray end face drives the crank rear end and slides and rotation in the same way along the sliding tray end face, the crank rear end also drives the rotation of tail vane when rotating, treat that the anglec of rotation stops linear electric motors behind desired location, tail vane is fixed on the angle position of setting by slide block and crank; In like manner, the reverse drive linear electric motors, the angle of tail vane also can realize reverse adjusting.
Principle of work: the angle of attack of wing plate
In the formula 1: d is the crank brachium;
L is the linear electric motors actuating length;
So according to formula 1 as can be known, the actuating length l that changes motor can change the corner α of tail vane simultaneously.
Beneficial effect:
1. system is simple, the reliability height: the present invention promotes a plurality of targets simultaneously with an actuating device and rotates simultaneously, has reduced the system complex degree, has improved system reliability.
2. control is simple: owing to adopt a driving to regulate a plurality of targets, the nonsynchronous problem of running that has caused when having avoided a plurality of drivings to drive respectively, control policy is simple relatively, reduces transmission device, and efficient improves.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing
As shown in Figure 1, linear electric motors 2 and slide block 7 are positioned on towed body afterbody shell 1 line of centers, and are fixed on towed body afterbody shell 1 inside, and slide block is connected on the axle of linear electric motors 2, towed body afterbody shell 1 circumferentially have 4 uniform axle sleeve mounting holes; As shown in Figure 2, slide block 7 is divided into leading portion, stage casing and back segment, slide block leading portion and back segment are cylindrical slide shaft, the stage casing is the sliding tray section, the leading portion of slide block 7 and back segment are sleeved in the axle sleeve II6 and can slide at axle sleeve II6 cathetus, sliding tray section middle part circumferentially has sliding tray one, and for ease of assembling, sliding groove wall has 4 circumferential five equilibriums and runs through the breach of sliding groove wall; As shown in Figure 3, crank 5 is divided into head end, linkage section and end, head end and the terminal two ends that lay respectively at linkage section and vertical with linkage section, the end diameter of crank 5 and sliding tray are little free-running fit, crank 5 ends are installed in the sliding tray of slide block 7, tail vane 4 is connected on crank 5 head ends, and can rotate with crank 5; Rotation distributes four cranks around the slide block center, and the rotation of four tail vanes is identical with respect to slide block 7 axis rotation directions when slide block 7 motions.During installation slide block 7 is turned an angle, adjust the position the terminal and slide block slot of crank 5 is alignd, swivel block 7 then, and crank end is embedded in the slide block slot, load onto fixing screw 8 at last, can prevent that crank end from deviating from from slide block slot.
