Abstract
The utility model relates to a novel deflector servomotor. The novel deflector servomotor comprises a bracket, supports, a deflector shaft, a deflector and a swing cylinder. The two supports are fixedly arranged on the upper plane of the bracket at intervals, and are coaxially provided with installment through holes; the deflector shaft is coaxially installed in the two installment through holes; both two sides of the deflector shaft are coaxially installed on the two supports through shaft sleeves; the middle of the deflector shaft between the two supports is connected with the deflector through keys and drive the deflector to swing with the deflector shaft as the axis; one end of the deflector extends out of the supports, and is connected with the swing cylinder through a flat key; the swing cylinder drives the deflector to swing back and forth. The novel deflector servomotor is simple in structure, low in cost, high in sensitivity, convenient to install and reliable in operation, saves space and is easy to arrange because the deflector is directly operated through the swing cylinder servomotor arranged in a housing case.
Description
Technical field
The utility model belongs to the field, water power plant, relates to the water power plant hydraulic turbine deflector, especially a kind of novel jet deflector servomotor.
Background technique
Jet deflector is the device that is contained in water power plant water turbine nozzle exit shunting; when shutdown or removal of load, by the speed regulator joint, operated; but all or part of jet of deflection makes it not directive bucket; present jet deflector is the straight-cylinder servomotor outside casing by arrangements of operations; thereby by change swaying direction operation jet deflectors such as connecting levers; structure is comparatively complicated, takes up room large.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of reasonable in design is provided, saves space, is easy to the jet deflector servomotor of arranging.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of jet deflector servomotor, comprise supporting plate, support, the jet deflector axle, jet deflector and swing cylinder, on supporting plate, interplanar is every being fixed with two stands, this two stands coaxially is shaped with installs through hole and the coaxial jet deflector axle of installing in this two installations through hole, these jet deflector axle both sides all coaxially are arranged on two stands by axle sleeve, jet deflector axle between two stands middle part connects jet deflector by key and drives jet deflector to take the jet deflector axle carries out rotation as axle, it is characterized in that: described jet deflector axle one end extends outside support and is connected with a swing cylinder by flat key, this swing cylinder drives the jet deflector axle to carry out reciprocating rotary.
And described swing cylinder is the internal helicoid structure.
Advantage of the present utility model and good effect are:
The utility model is simple in structure, with low cost, highly sensitive, easy for installation, reliable, adopts the swing cylinder servomotor direct control jet deflector be arranged in casing, saves space, is easy to arrange.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The right TV structure schematic diagram that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of jet deflector servomotor, comprise supporting plate 9, support 8, jet deflector axle 6, jet deflector 4 and swing cylinder 2, on supporting plate, interplanar is every being fixed with two stands, this two stands coaxially is shaped with to be installed through hole and in this two installations through hole, a jet deflector axle is installed, these jet deflector axle both sides all coaxially are arranged on two stands by axle sleeve 7, and jet deflector axle between two stands middle part connects jet deflectors by key 5 and drives jet deflector to take the jet deflector axle carries out rotation as axle.
Described jet deflector axle one end extends outside support and is connected with a swing cylinder by flat key 3, and this swing cylinder drives jet deflector axle to carry out reciprocal rotation in set angle.
Described swing cylinder is the internal helicoid structure, and the straight line motion by piston and tooth bar is converted into and rotatablely moves.
Swing cylinder mentioned in the utility model belongs to prior art, and its internal structure is not described in detail.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
Claims (2)
