They use compressed air generated by the air pump to push the bolt wrench to perform work. However, it is inconvenient to carry, and the large truck driver is not convenient to self-removal the vehicle bolts due to lack of power in the field.
因此， 需要一种节约能源、 便于携带， 而又可以持续做功的流体动力装 置。 发明内容  Therefore, there is a need for a fluid power device that saves energy, is easy to carry, and can continue to work. Summary of the invention

在一个实施例中，提供了一种流体动力装置， 其包括压力辅助器以及束 流产生器。压力辅助器用于为所述流体动力装置提供输入压力。 束流产生器 与压力辅助器相连接。 束流产生器包括： 具有流体入口和流体出口的流体存 储罐；可在流体存储罐内密封滑动并在流体存储罐内分隔出第一存储腔和第 二存储腔的束流产生活塞； 连接在压力辅助器和束流产生活塞之间的力杆， 力杆将庄力辅助器的作用力传递至束流产生活塞， 使得束流产生活塞滑动， 进而推动流体存储罐内的流体从流体出口流出， 产生流体动力。 In one embodiment, a fluid power device is provided that includes a pressure aid and a beam generator. A pressure aid is used to provide input pressure to the fluid power device. The beam generator is connected to the pressure aid. The beam generator includes: a fluid storage tank having a fluid inlet and a fluid outlet; sealing slippage within the fluid storage tank and separating the first storage chamber and the first in the fluid storage tank The beam of the two storage chamber generates a piston; a force rod connected between the pressure assister and the beam generating piston, the force rod transmits the force of the Zhuangli aid to the beam generating piston, so that the beam generates piston sliding, and then pushes Fluid in the fluid storage tank flows out of the fluid outlet to generate fluid power.
其中， 流体存储罐具有第一流体入口、 第一流体出口以及第二流体入口 和第二流体出口， 其中， 第一存储腔与第一流体入口和第一流体出口相连， 第二存储腔与第二流体入口和第二流体出口相连，当束流产生活塞.^ L推压第 一存储腔的运动时， 第一流体入口和第二流体出口关闭， 而第一流体出口和 第二流体入口打开， 第一存储腔内的流体从第一流体出口流出， 且有流体经 第二流体入口流入第二存储腔内。  Wherein the fluid storage tank has a first fluid inlet, a first fluid outlet, and a second fluid inlet and a second fluid outlet, wherein the first storage chamber is connected to the first fluid inlet and the first fluid outlet, and the second storage chamber is The two fluid inlets are connected to the second fluid outlet, and when the beam generating piston moves the first storage chamber, the first fluid inlet and the second fluid outlet are closed, and the first fluid outlet and the second fluid inlet are opened. The fluid in the first storage chamber flows out of the first fluid outlet, and the fluid flows into the second storage chamber through the second fluid inlet.
进一步地， 束流产生器配置使得， 当束流产生活塞做推压第二存储腔的 运动时， 第一流体出口和第二流体入口关闭， 而第一流体入口和第二流体出 口打开， 第二存储腔内的流体从第二流体出口流出， 且有流体经第一流体入 口流入第一存储腔内， 并且，从第二流体出口流出的流体回流到第二流体入 口附近， 以便于循环使用。  Further, the beam generator is configured such that when the beam generating piston moves to urge the second storage chamber, the first fluid outlet and the second fluid inlet are closed, and the first fluid inlet and the second fluid outlet are opened, The fluid in the two storage chambers flows out of the second fluid outlet, and the fluid flows into the first storage chamber through the first fluid inlet, and the fluid flowing out from the second fluid outlet flows back to the second fluid inlet to facilitate recycling. .
其中第一流体入口和第一流体出口内均具有流体单向导通阀，并且第一 流体入口和第一流体出口通过一段共用的流体出入口与第一存储腔连通。可 选地是， 第一流体入口和第一流体出口可单独地与第一存储腔连通。  Wherein the first fluid inlet and the first fluid outlet each have a fluid single-way valve, and the first fluid inlet and the first fluid outlet are in communication with the first storage chamber through a common fluid inlet and outlet. Optionally, the first fluid inlet and the first fluid outlet are separately connectable to the first storage chamber.
在又一个实施例中， 压力辅助器包括压力腔、 置于压力腔内的压力辅助 活塞以及与压力腔相连的压力辅助流体出口和压力辅助流体入口，力杆的两 端分别连接束流产生活塞和压力辅助活塞。  In still another embodiment, the pressure assistor includes a pressure chamber, a pressure assisting piston disposed in the pressure chamber, and a pressure assisting fluid outlet and a pressure assisting fluid inlet connected to the pressure chamber, the two ends of the force rod being respectively connected to the beam generating piston And pressure assisted pistons.
另夕卜，可选的是，压力辅助器包括驱动器以及由驱动器所驱动的驱动轮， 力杆的邻近压力辅助器的一端具有条形齿轮， 条型齿轮与驱动轮啮合，使得 束流产生活塞可通过力杆而在驱动器的带动下滑动。  In addition, optionally, the pressure assistor comprises a driver and a driving wheel driven by the driver, and the end of the force bar adjacent to the pressure assister has a bar gear, and the bar gear meshes with the driving wheel, so that the beam generates a piston It can be slid by the driver with the force lever.

The fluid power device further includes a barrier piece, the barrier piece is annular, disposed at a junction of the second storage cavity and the pressure chamber, and the force bar passes through the barrier piece, so that the barrier piece blocks the second storage cavity from the pressure chamber fluid Open.

本发明的流体动力装置可以将基本恒定的较小动力输入转化为持久的 高速、 高压流体动力输出。 其不受能源短缺的影响， 可以组成便于携带的流 体动力装置。 The fluid power device of the present invention can convert a substantially constant small power input into a durable High speed, high pressure fluid power output. It is not affected by the energy shortage and can constitute a portable fluid power device.
具体的来讲， 可在该流体动力装置的流体出口处设置发电机叶轮， 由于 流出的流体具有高压、 高速的特点， 可以实现发电机的正常发电。 可以根据 具体需要的发电量来调节输入的庄强，以及调节输出流体的流速以及流量大 小。由于压力辅助器仅需要逐步输入较小压力即可实现流体存储罐内持久的 大致稳定压力以供给高压流体， 所以， 可采用现有技术中常见的压力油泵或 者手动气泵来用作压力辅助器。  Specifically, the generator impeller can be disposed at the fluid outlet of the fluid power device, and the normal power generation of the generator can be realized because the fluid flowing out has the characteristics of high pressure and high speed. The input strength can be adjusted according to the amount of power generation required, as well as the flow rate of the output fluid and the flow rate. Since the pressure assister only needs to input a small pressure step by step to achieve a substantially constant pressure in the fluid storage tank to supply the high pressure fluid, a pressure oil pump or a manual air pump which is common in the prior art can be used as the pressure assister.
比如在手摇式发电机的应用场合， 采用本发明的手摇式发电机， 使用者 只需要通过压力辅助器手摇输入一定的压力之后， 可以休息一段时间， 而发 电机则不停止发电。 等到流体存储罐内压力小到不能输出高压束流时， 使用 者再行逐步输入压力即可维持下一节段的工作。  For example, in the application of a hand-cranked generator, with the hand-cranked generator of the present invention, the user only needs to manually input a certain pressure through the pressure assister, and can rest for a period of time, while the generator does not stop generating electricity. When the pressure in the fluid storage tank is too small to output the high pressure beam, the user can gradually input the pressure to maintain the next section.
再如在气动螺栓扳手的应用场合， 只需要在流体存储罐内输入气体即 可。 且在野外使用时， 完全可以通过手动供给辅助压力来保持流体存储罐内 的高压， 进而实现气动螺栓扳手的正常工作。 附图说明  As in the case of pneumatic bolt wrenches, it is only necessary to input gas into the fluid storage tank. When used in the field, it is completely possible to maintain the high pressure in the fluid storage tank by manually supplying the auxiliary pressure, thereby realizing the normal operation of the pneumatic bolt wrench.

请参考图 1， 其显示了根据本发明的流体动力 置 100的一个实施例的 示意图。 此流体动力装置 100包括压力辅助器 140以及束流产生器 120。 压 力辅助器 140和束流产生器 120可通过各自的凸缘结构 151、 152相互连接 起来。 压力辅助器 140包括压力腔（未标示）、 置于压力腔内的压力辅助活 塞 136以及与压力腔相连的压力辅助流体出入口 144、 146。  Referring to Figure 1, there is shown a schematic diagram of one embodiment of a fluid power device 100 in accordance with the present invention. This fluid power device 100 includes a pressure assistor 140 and a beam generator 120. The pressure assister 140 and the beam generator 120 are interconnected by respective flange structures 151, 152. The pressure assistor 140 includes a pressure chamber (not shown), a pressure assisting piston 136 disposed within the pressure chamber, and pressure auxiliary fluid inlets and outlets 144, 146 coupled to the pressure chamber.
束流产生器 120包括：具有流体入口和流体出口的流体存储罐 121、122； 可在流体存储罐内密封滑动并在流体存储罐内分隔出第一存储腔 121 和第 二存储腔 122的束流产生活塞 123; 连接在压力辅助活塞 136和束流产生活 塞 123之间的力杆 135。 在第二存储腔 122与压力腔的结合处设有呈环状的 阻隔片 142。 力杆 135穿过阻隔片 142， 使得阻隔片 142将第二存储腔 122 与压力腔阻隔开来， 防止以上两个腔之间的流体相互连通。 束流产生活塞 123的直径至少是压力辅助活塞 136的直径的 3倍（优选为 5倍以上， 最优 为 10倍以上） ， 以便明显地体现出压力积累的效果。 在束流产生活塞 123 的两侧设置有第一挠性气嚢 124和第二挠性气嚢 125。 挠性气嚢 124、 125 由具有弹性的包裹物 （如弹性体袋） 密封气体而组成。 挠性气囊 124、 125 可在压力的作用下缩小， 一旦压力变小则可以逐步恢复原状， 以促进流体动 力输出的持续均匀性。  The beam generator 120 includes: a fluid storage tank 121, 122 having a fluid inlet and a fluid outlet; a bundle slidable within the fluid storage tank and separating the first storage chamber 121 and the second storage chamber 122 within the fluid storage tank The flow generating piston 123; a force rod 135 connected between the pressure assisting piston 136 and the beam generating piston 123. A ring-shaped barrier piece 142 is provided at the junction of the second storage chamber 122 and the pressure chamber. The lever 135 passes through the barrier 142 such that the barrier 142 blocks the second reservoir 122 from the pressure chamber to prevent fluid communication between the two chambers. The beam generating piston 123 has a diameter at least three times (preferably 5 times or more, preferably 10 times or more) the diameter of the pressure assisting piston 136 in order to clearly exhibit the effect of pressure accumulation. A first flexible gas cylinder 124 and a second flexible gas cylinder 125 are disposed on both sides of the beam generating piston 123. The flexible gas cylinders 124, 125 are composed of a flexible wrap (e.g., an elastomer bag) to seal the gas. The flexible bladders 124, 125 can be shrunk under pressure and once the pressure is reduced, they can be gradually restored to promote continuous uniformity of fluid power output.
第一存储腔 121具有第一流体入口 127、 第一流体出口 126。 第二存储 腔 122具有第二流体入口 128和第二流体出口 129。 第一流体入口 127、 第 一流体出口 126、 第二流体入口 128以及第二流体出口 129内分别具有流体 单向导通阀 131、 132、 133、 134。 第一流体入口 127和第一流体出口 126 通过一段共用的流体出入口 （未标示）与第一存储腔 121连通。 第二流体入 口 128和第二流体出口 129通过一段共用的流体出入口（未标示）与第二存 储腔 122连通。 此外， 可以设置相应的流体回收结构（图未示） ， 使得从流 体出口流出的流体做功之后， 再回收到流体入口附近， 便于循环利用。  The first storage chamber 121 has a first fluid inlet 127 and a first fluid outlet 126. The second reservoir 122 has a second fluid inlet 128 and a second fluid outlet 129. The first fluid inlet 127, the first fluid outlet 126, the second fluid inlet 128, and the second fluid outlet 129 have fluid single-way valves 131, 132, 133, 134, respectively. The first fluid inlet 127 and the first fluid outlet 126 are in communication with the first storage chamber 121 through a common fluid inlet (not shown). The second fluid inlet 128 and the second fluid outlet 129 are in communication with the second reservoir 122 through a common fluid inlet (not shown). In addition, a corresponding fluid recovery structure (not shown) may be provided so that the fluid flowing out of the fluid outlet is recycled to the vicinity of the fluid inlet for recycling.
下面将结合图 2和图 3来具体介绍本发明的流体动力装置 100的工作过 程。 参考图 2， 首先通过压力辅助流体出入口 146逐步注入高压流体（比如 油、 水或者空气） ， 此时压力腔内的部分流体通过压力辅助流体出入口 144 流出。 压力辅助活塞 136受压向左推动 （图 2中箭头 A所示方向） ， 同时 推动力杆 135和束流产生活塞 123左移。束流产生活塞 123做推压第一存储 腔 121的运动， 第一流体入口 127和第二流体出口 129关闭， 而第一流体出 口 126和第二流体入口 128打开。第一存储腔 121内的流体从第一流体出口 126沿箭头 A，方向流出， 且有流体经第二流体入口 128沿箭头 A"方向流入 第二存储腔 122内。 同时， 第一挠性气嚢 124由于受压而压缩。 由于束流产 生活塞 123和压力辅助活塞 136之间直径的明显差异，即使停止向压力腔逐 步注入高压流体， 只要压力腔内存有压力， 仍可以保持束流产生活塞 123 推动第一存储腔 121流出流体。随着压力辅助器 140压力腔内的压力逐渐变 小， 第一挠性气嚢 124会逐步恢复原状， 这样可使得在最后的阶段， 仍可有 流体从第一流体出口 126流出。 The operation of the fluid power device 100 of the present invention will be specifically described below with reference to Figs. 2 and 3. Referring to FIG. 2, a high pressure fluid (such as oil, water or air) is first injected through the pressure assist fluid inlet and outlet 146, at which time a portion of the fluid in the pressure chamber passes through the pressure assist fluid inlet and outlet 144. Flow out. The pressure assisting piston 136 is urged to the left (in the direction indicated by the arrow A in Fig. 2) while the urging force lever 135 and the beam generating piston 123 are moved to the left. The beam generating piston 123 acts to push the first storage chamber 121, the first fluid inlet 127 and the second fluid outlet 129 are closed, and the first fluid outlet 126 and the second fluid inlet 128 are open. The fluid in the first storage chamber 121 flows out from the first fluid outlet 126 in the direction of the arrow A, and the fluid flows into the second storage chamber 122 in the direction of the arrow A" through the second fluid inlet 128. Meanwhile, the first flexible gas The crucible 124 is compressed due to the pressure. Since the beam produces a significant difference in diameter between the piston 123 and the pressure assisting piston 136, even if the high pressure fluid is gradually injected into the pressure chamber, the beam can be maintained to generate the piston as long as there is pressure in the pressure chamber. 123 pushes the first storage chamber 121 out of the fluid. As the pressure in the pressure chamber of the pressure assistor 140 gradually becomes smaller, the first flexible gas bulb 124 gradually returns to its original state, so that in the final stage, there is still fluid flow. The first fluid outlet 126 flows out.
参考图 3， 首先通过压力辅助流体出入口 144逐步注入高压流体（比如 油、 水或者空气） ， 此时压力腔内的部分流体通过压力辅助流体出入口 146 流出。 压力辅助活塞 136受推而向右推动 （图 3 中箭头 B所 方向） ， 同 时拉动力杆 135和束流产生活塞 123右移。束流产生活塞 123做推压第二存 储腔 122的运动， 第一流体出口 126和第二流体入口 128关闭。 第一流体入 口 127和第二流体出口 129打开， 第二存储腔 122内的流体沿箭头 B"方向 从第二流体出口 129流出， 且有流体经第一流体入口 127沿箭头 B，方向流 入第一存储腔 121内。 同时， 第二挠性气嚢 125由于受压而压缩。 由于束流 产生活塞 123和压力辅助活塞 136之间直径的明显差异，即使停止向压力腔 逐步注入高压流体， 只要压力腔内存有压力， 仍可以保持束流产生活塞 123 推动第二存储腔 122流出流体。随着压力辅助器 140压力腔内的压力逐渐变 小， 第二挠性气嚢 125会逐步恢复原状， 这样可使得在最后的阶段， 仍可有 流体从第二流体出口 129流出。  Referring to Figure 3, a high pressure fluid (e.g., oil, water, or air) is first injected through the pressure assist fluid inlet and outlet port 144, at which point a portion of the fluid within the pressure chamber exits through the pressure assist fluid inlet and outlet 146. The pressure assisting piston 136 is pushed and pushed to the right (in the direction of arrow B in Fig. 3), while the pulling power rod 135 and the beam generating piston 123 are moved to the right. The beam generating piston 123 acts to urge the second reservoir 122, and the first fluid outlet 126 and the second fluid inlet 128 are closed. The first fluid inlet 127 and the second fluid outlet 129 are open, the fluid in the second storage chamber 122 flows out of the second fluid outlet 129 in the direction of arrow B", and the fluid flows in the direction of arrow B through the first fluid inlet 127. At the same time, the second flexible gas cylinder 125 is compressed due to the pressure. Since the beam generation produces a significant difference in diameter between the piston 123 and the pressure auxiliary piston 136, even if the high pressure fluid is gradually injected into the pressure chamber, as long as There is pressure in the pressure chamber, and the beam generating piston 123 can be kept to push the second storage chamber 122 out of the fluid. As the pressure in the pressure chamber of the pressure assistor 140 becomes smaller, the second flexible gas cylinder 125 gradually returns to its original state. This will allow fluid to flow out of the second fluid outlet 129 at the final stage.
