(三)有益效果(3) Beneficial effects
与现有技术相比,本发明提供了一种微型智能远程控制电液执行器,具备以下有益效果:Compared with the prior art, the present invention provides a miniature intelligent remote control electro-hydraulic actuator, which has the following beneficial effects:
1、该微型智能远程控制电液执行器,通过微型动力单元内部的驱动电机带动齿轮泵转动输出高压液压油,微型动力单元输出的高压液压油经过阀块进入液压执行器内的液压缸套,推动齿条直行程运动,齿条带动齿轴做角行程运动,齿轴再带动主齿轮转动,主齿轮又带动其外侧的从齿轮转动,使从齿轮上的角度编码器在从齿轮转动时会接收到电器脉冲信号,通过4-20mA的控制反馈模块转换与角度变化位置成线性比例的4-20mA的信号,随着电液动执行器角度变化,电流信号也跟着改变,信号从关到开逐渐增加,从开到关逐渐减小,始终保持电液动执行器0-90°角度转动,电流变化值处在4-20mA内,再通过控制反馈模块将转动的角度通过蓝牙模块上传至手机APP客户端或者计算机终端,实现远程监控,达到了方便使用的目的。1. The micro intelligent remote control electro-hydraulic actuator drives the gear pump to rotate and output high pressure hydraulic oil through the drive motor inside the micro power unit. The high pressure hydraulic oil output from the micro power unit enters the hydraulic cylinder liner in the hydraulic actuator through the valve block. Push the rack to move in a straight stroke, the rack drives the pinion to make an angular motion, the pinion drives the main gear to rotate, and the main gear drives the outer secondary gear to rotate, so that the angle encoder on the secondary gear will rotate when the secondary gear rotates. After receiving the electrical pulse signal, the 4-20mA signal that is linearly proportional to the angle change position is converted through the 4-20mA control feedback module. As the angle of the electro-hydraulic actuator changes, the current signal also changes, and the signal changes from off to on. Gradually increase, gradually decrease from on to off, always keep the electro-hydraulic actuator rotating at an angle of 0-90°, the current change value is within 4-20mA, and then upload the rotation angle to the mobile phone through the Bluetooth module through the control feedback module APP client or computer terminal to realize remote monitoring and achieve the purpose of convenient use.

The miniature intelligent remote control electro-hydraulic actuator can stop at any angle between 0-90° by controlling the miniature intelligent electro-hydraulic actuator, and use the internal hydraulic lock to keep the angle unchanged. On the premise of the cover, monitoring its action through a mobile phone or a computer can also achieve rapid adjustment of faults, and the temperature sensor will monitor the temperature of the drive motor inside the driver in real time, and upload the temperature information to the mobile APP client through the Bluetooth module And computer terminal, it is convenient to check the temperature, and when the temperature is higher than a certain upper limit, it sends a signal to the temperature control switch to power off the drive motor, which plays a good protective role. The intelligent electro-hydraulic actuator adopts closed-loop oil circuit control. Solve the big problem that the oil leakage of ordinary hydraulic actuator pipeline cannot find the leakage point. At the same time, there is a hydraulic interlocking system valve inside the micro power unit, which can be effectively locked in the stop state, and even if the power supply loses power, it can also maintain the position where it stayed. , without the need for dry air or air purification device like pneumatic actuators, convenient and simple connection with the computer, more suitable for the use of new electronic information technology, to achieve the purpose of convenient use.
