TW201928185A - Water blocking gate panel pinching and pressing control device that comprises a current feedback signal unit to feed a current feedback signal to a signal processing interface unit to automatically shut down an extendable actuator - Google Patents

Abstract

A water blocking gate panel pinching and pressing control device utilizes a pinching and pressing control device for operation control of an extendable actuator. In a process that the extendable actuator performs a forwarding operation to drive a push/pull bar to move a pinching and pressing bar to pinch and press against a surface of a water blocking panel, power consumed by the extendable actuator gets higher when tightness of an opposite surface of the water blocking panel positioned against an opening seal rubber strip is being increased. When the water blocking panel being positioned against the opening seal rubber strip reaches predetermined tightness, a current feedback signal transmitted from a current feedback signal unit to a signal processing interface unit is larger than a current threshold value, such that the operation of the extendable actuator is automatically shut down. Therefore, the water blocking gate does not need a limit switch or a sensor switch to detect a forwarding process of the extendable actuator and complicated calibration or error correction of the energy that is transmitted to the pinching and pressing bar by a forwarding push force of the extendable actuator can be avoided or reduced, and reliability of water tightness of the water blocking panel can be improved.

Description

   Waterproof gate door plate clamping control device   

The invention relates to a waterproof gate door clamping control device that uses a telescopic actuator as a watertight clamping force of a waterproof door panel, which can avoid or reduce tedious adjustment or error adjustment of thrust energy, and has improved watertight reliability of the waterproof door panel.

According to the causes of global climatic changes, various natural disasters occur frequently, such as typhoons and floods, causing loss of people's lives and property. The use of waterproof gates can reduce the damage caused by floods invading indoors or basements. Or the use of electric waterproof gates in public places is the most affirmative; conventional electric waterproof gates, such as Taiwan's No. M534234 "Waterproof gate door plate pushes the clamped watertight structure" new patent case, the waterproof door panel descends into the rail of the door rail The waterproof door wall is formed by connecting a pull rod in the door rail through the telescopic end of the telescopic actuator in the chassis, and the clip direction is changed by the clip. One side of the door panel is clamped, so that the other end of the waterproof door panel is in close contact with a rubber strip in the door rail to produce a watertight (waterproof) effect; although the telescopic end extension process and the retracting action of the telescopic actuator can push the clamp The pressure lever pinches or leaves the waterproof door panel, however, the pinch lever stops the timing of the pinching action of the waterproof door panel or leaves the stop return motion. Machine, it is necessary to rely on induction or detection of switching elements to convey the telescopic actuator stop motion information, that is, the telescopic end extension process of the telescopic actuator is a process limit switch (such as a touch switch) on the transmission path, when the waterproof door panel When the pinch lever is pushed to reach a predetermined water-tightness, the limit switch of the process (switching of the electric control circuit of the power end of the telescopic actuator) is controlled in time to control the telescopic actuator to stop the process action. Obviously, the pinch lever is pushed The timing of stopping the pressure of the waterproof door panel is completely determined by the reaction point of the limit switch of the process. The response is too fast. The waterproof door panel does not fit tightly with the sealing strip. If the response is too slow, the sealing strip is deformed too much to reduce the waterproof ability. In general, the slight displacement of the clamping rod at the final stage will have a huge impact on the clamping force of the waterproof door panel. The limit switch is not a precision sensing element in the electronic control field (the trigger response tolerance is large). The multi-link transmission mechanism between the pull rod and the clamping rod must have a large error in the force transmission action. Therefore, the installation of the waterproof gate must cost a lot Force, tediously check or correct the operation consistency of the transmission link and adjust the action position or trigger reaction point of the limit switch; although mechanical limit switches can be replaced with photoelectric switching elements to increase the control precision, only multi-link transmission The mechanism does not simply reduce the inspection manpower from the precision of the machining dimensions produced by the connecting rod.
