Embodiment Construction

[0009] The bistable automatic water injection control mechanism is mainly composed of a pendulum block 1, a bracket 2, a connecting plate 3, a vertical rod 4, a float 5, a rocker arm 6, a controller 7, a large counterweight 8, and a small counterweight 9. The pendulum block 1. The large counterweight 8 and the small counterweight 9 are fixed together, the pendulum 1 is hinged on the bracket 2 at point A, the pendulum 1 can rotate around A relative to the bracket 2, and the rocker arm 6 is hinged at point B On the bracket 2, the rocker arm 6 can rotate around B relative to the bracket 2, the float 5 is fixed on the vertical bar 4, the vertical bar 4 is hinged with the pendulum block 1, and the two ends of the connecting plate 3 are connected with the pendulum block 1 and the pendulum block 1 respectively. Rocking arm 6 is hinged, and the upper end of controller 7 is hinged with rocking arm 6 together. When the water level in the paddy field, water tower or water storage tank dr...

Abstract

The invention relates to a double-stability automatic water injection control mechanism which keeps a water level control valve at a double-stability state and belongs the field of automatic control devices. The mechanism comprises swing blocks, a support, a connecting plate, a vertical rod, a floater, a rocker, a controller, a large counter balance and a small counter balance. The swing blocks are hinged on the support, and are respectively arranged on both sides of a hinge point when water is injected and stopped; the rocker is hinged on the support; the floater is fixedly arranged on the vertical rod; the vertical rod is hinged with the swing blocks; both ends of the connecting plate are respectively hinged with the swing blocks and the rocker; the upper end of the controller is hinged with the rocker; the floater is fixed arranged on the vertical rod; the vertical rod and the swing blocks are hinged together; both ends of the connecting plate are respectively hinged with the swing blocks and the rocker; and the upper end of the controller is hinged with the rocker. When the water is injected or stopped, the controller of the double-stability automatic water injection control mechanism always keeps a stable state.

Description

Technical field [0001] The invention relates to a bistable automatic water injection control mechanism for keeping a water level controller in two stable states, and belongs to the technical field of automatic control. Background technique [0002] At present, the irrigation of paddy fields, the water level control of water towers or storage tanks, etc. mainly adopt the method of manual control, and control whether to inject water by manually opening or closing the valve of the water pipe. This method requires external force to rotate the valve switch, which is time-consuming and labor-intensive, and cannot realize automatic control. There is another kind of electric control mechanism that can realize keeping the water level at a certain height, but the shortcoming of this control mechanism is that it needs to provide electric energy, which is not conducive to energy saving. In recent years, some progress has been made in the research on the automatic control mechanism of w...
