Abstract

A care movement device, this device have a wheel at least, and its central shaft is contained on the bearing of underframe.Wheel is divided into and manyly is fan-shaped compartment and concentricity cylindrical body is connected, and is marked with the liquid of some, constitutes variable volume chambers by means of the sideboard that is connected on the central cylinder.Respectively at lower whorl on the wheel on week, with an arrestment mechanism enclosed compartment, with a unlocking mechanism open compartment.When wheel clockwise rotated, the compartment that is positioned at the wheel lower right part was opened, and the compartment that is positioned at lower left quarter seals, and situation is then opposite when rotating counterclockwise.

Description

Actuator

The invention relates to the actuator that is referred to as the continous way compressor.

The object of the present invention is to provide a kind of novel actuator, be used for carrying out pump and drag, dragging of well water pump or irrigation pump for example, perhaps other any equipment that needs power or moment of torsion drags.

The objective of the invention is to reach: it is characterized in that by a kind of like this actuator, has a wheel at least, the central shaft of wheel is installed on the bearing that rigid frame supported, that cooperatively interact, wheel is divided into many fan-shaped compartments that are basically, have a liquid that is connected with the center Cylinder and is marked with to not a half compartment in per two compartments at least, and constitute variable volume chambers by the sideboard that is connected on the Cylinder of center and can be locked on the closing position; This transmission device, its feature also is, a counterweight arrestment mechanism and a unlocking mechanism that unclamps sideboard that is used for enclosed compartment is arranged, the counterweight arrestment mechanism is installed at the bottom of the above-mentioned wheel near the point, unlocking mechanism is then taken turns Zhou Qidong on above-mentioned wheel, therefore, each compartment that is in wheel lower right part position is all opened, and each compartment that is in wheel lower left quarter position all seals.Be like this when wheel moves in the direction of the clock, when wheel rotated by counter clockwise direction, situation was then opposite.

For simplicity, in the following description, suppose that wheel moves in the direction of the clock.

When wheel turns, the liquid of last compartment of wheel lower right is pressed in the Cylinder of center, so that flow to the open compartment that enters wheel lower right part position.Because the counterweight arrestment mechanism stops the sideboard of above-mentioned compartment to rotate, prop up the relevant fixed dam actually of qualification on opposite until this baffle plate, so the volume pressurized of last compartment and dwindling.This compartment that liquid is housed enters the upper left quarter position of wheel subsequently, and liquid is discharged from compartment there fully.When this compartment enters the position, upper right, just from unlocking mechanism below by, unlocking mechanism unclamps sideboard, baffle plate drops on the block by deadweight, and like this, the space of compartment reaches maximum volume, at this moment, just can accept the water that another compartment discharged that above the counterweight arrestment mechanism, passes through.

According to most preferred embodiment, for guaranteeing the wheel smooth rotation, actuator of the present invention on same central shaft, to install at least two similar but the wheel of certain angular difference is arranged.

In conjunction with the accompanying drawings, can further understand other details of the present invention by introducing an embodiment.

-Fig. 1 is the side view of actuator of the present invention;

-Fig. 2 is the front view of actuator of the present invention;

-Fig. 3 is the sectional drawing by the bellows of variable volume chambers.

See figures.1.and.2, actuator 1 of the present invention has two

wheels

2 and 3, is installed on the same central shaft 5, and angular difference is arranged each other.

For clarity sake, Fig. 1 only draws a wheel 2.

Central shaft 5 is installed on rigid frame 11

bearings

7,9 that supported, that cooperatively interact.

Each

wheel

2,3 all is divided into many fan-shaped compartments 13,15.As shown in the figure, by means of sideboard 13 ' (preferably with the center Cylinder on 14 link to each other), making just has a compartment to become a variable volume chambers 13 in two compartments.As shown in Figure 3, variable volume chambers 13 is fine in abutting connection with getting with bellows 19.Bellows 19 is connected with center Cylinder 17 by suitable inlet 21, and bellows is abutted against pipe box and is fixed on these inlets, takes over the most handy stainless steel material of cover and makes.Sideboard should be able to be positioned on the position that makes variable volume chambers volume minimum.This locking device preferably is made of the swing hook 23 of band counterweight 25, and the swing hook of device tangles in case the outer end of sideboard is locked, and baffle plate just can not rotate; In case counterweight 25 makes the hook swing, promptly near the wheel son vertex, to swing, locking device just unclamps sideboard.

Actuator of the present invention also has a counterweight arrestment mechanism 27, during wheel turns it control sideboard 13 ', until 13 ' prop up the fixed dam on opposite and the device 23 that is locked pins.Then, counterweight spring 28 can make above-mentioned arrestment mechanism 27 swings.

Preferably inject liquid by central shaft.In addition, center Cylinder 17 also has liquid level control apparatus and peep hole.

Ideal method is to obtain power on central shaft 5, also can be by obtaining energy with a kind of transmission device (not drawing among the figure) of having an effect in the wheel week of wheel 1.In addition, above-mentioned central shaft 5 can extend, so that several actuators according to the present invention are together in series.

According to embodiment preferably, bellows 19 is made of several compartments that are interconnected 31,33,35.Also be necessary to load onto the exhaust expansion bellows (not drawing among the figure) that the gas that may exist in the closed circuit can be discharged.Like this, just can guarantee to inject liquid to greatest extent, and prevent baffle plate adhesion with other bellows.

Each wheel also can assemble a kind of complemental brake system, and this complemental brake system is made of a series of steamboats, utilizes a counterweight, can steamboat be pressed in the wheel of wheel on week by certain adjustable power.For preventing that wheel is out of shape because of torsion, this complemental brake system can be divided into two partly.

Wheel is divided into the baffle plate of two fan-shaped compartments, preferably constitutes with the plank of metal framework or by sheetmetal by bag.

According to embodiment preferably, the swing of sideboard is stoped by block (not drawing among the figure), and the cushioning members of elastic material and so on preferably is housed on the block.

Basic characteristics of actuator of the present invention are, design is simple, and convenient disassembly is convenient to transportation and is stored.

The liquid that uses can be water, can in water, add antifreezing agent with (or) anticorrisive agent. Also can use other the various liquid as oil.

Obviously, the present invention is not limited to described embodiment, but can be in claim institute Extend in the scope of regulation.

Therefore, being fan-shaped compartment can tangentially be installed on the central cylinder, and the operation principle that can't change actuator of the present invention.

Also must be pointed out, baffle plate, the base of the metal framework of wheel, two compartments of separation, etc., be to use electroplating steel products, the erosion-resisting metal material such as aluminium makes.

Obviously, the rotation direction of wheel is can be optional, the situation that same above described hypothesis wheel moves in the direction of the clock is opposite, can select counter-rotation, if wheel is by counterclockwise rotating, so, the compartment that is in position, wheel lower left is opened, and the compartment that is in position, wheel lower right seals.
