Automatic water level control weir gate

Abstract

The invention provides an automatic water level control weir gate. The automatic water level control weir gate comprising a water fender, a water fender frame, a rotating force arm assembly, a balanced force arm, connecting rod assemblies, a central force arm shaft, counter weights, a fixing frame, a balanced water cylinder and a shaft seat. The balanced force arm is connected to the central force arm shaft through the connecting rod assemblies connected in series. The central force arm shaft is installed on the water fender frame. The water fender is fixed to the water fender frame. The counter weights are fixed to the balanced force arm through fastening nuts. The position of the central force arm shaft on the water fender frame is adjustable, and therefore the function of adjusting the angle of the balanced force arm is achieved. According to the automatic water level control weir gate, the angle of the weir gate can be adjusted by adjusting the weight of the counter weights so that the upstream water level of the weir gate can be adjusted; if the counter weights are different, the opening angles of the water fender are different, and therefore the purpose of controlling the water level is achieved; the function of adjusting the angle of the balanced arm can also be achieved by adjusting the position of the central force arm shaft on the water fender frame. The whole automatic water level control weir gate is simple in structure and rapid in response.

Description

technical field [0001] The invention belongs to the technical field of drainage, in particular to an automatic control weir gate capable of precisely controlling the water level. Background technique [0002] The weir gate is a gate set at the mouth of the weir to adjust the height of the weir. It is a key device for controlling a relatively stable liquid storage area. For example, it is necessary to create a relatively stable water storage area for canals, ponds, and small rivers. In the process of sewage treatment, it is necessary to create a relatively stable water storage area so that the sewage can be disinfected, sterilized, and precipitated smoothly. The current water level control devices include water level control gates, weir gates, flap gates, floating gates, etc. Among them, the water level control weir gate has a single form and poor structure. There are basically two types, one is the fixed water level control weir gate, and the other is the fixed water level c...

The current water level control devices include water level control gates, weir gates, flap gates, floating gates, etc. Among them, the water level control weir gate has a single form and poor structure. There are basically two types, one is the fixed water level control weir gate, and the other is the fixed water level control weir gate. This kind of weir gate is just a fixed retaining wall, and the interception length is 10 to 20 times the width of the water flow, which increases the construction cost and is difficult to maintain. Moss and scale will grow over time and it is difficult to remove. Water can only come from the weir gate. The other is the electric water level control weir gate, which works by lifting or lowering the gate, but requires gates, motors, water level sensors, drives and transmissions. Devices, etc., have complex structures, low response sensitivity, prone to failure, difficult to install and disassemble, and high construction costs
