Array-tube-type weir gate

Abstract

The invention relates to an array-tube-type weir gate which comprises a chassis, an inclined plate and rapid water drain pipes, wherein the front section of the chassis is provided with a triangular space frame on which the inclined plate is aslant and fixedly arranged; the lateral lower edge of the inclined plate is hermetically and fixedly connected with the bottom of a water channel; two lateral edges of the inclined plate are hermetically and fixedly connected with two side walls of the water channel; and the rapid water drain pipes are hermetically, vertically and uniformly distributed on the inclined plane of the inclined plate at intervals. The weir gate provided by the invention is simple in structure, low in construction cost, convenient and rapid in installation, convenient in regulation and diverse in structural combination form, can widely adapt to fields, can adapt to different amounts of water, is rapid in water drain speed, can automatically regulate and control the water level, and is high in water level control accuracy, reliable in operation, free from maintenance, energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a liquid level control device for a channel, in particular to an array tubular weir gate. Background technique [0002] At present, there are many forms of liquid level control in the corresponding process sections of sewage plants or waterworks, such as electric weir gates, electric gates, fixed weirs, flap gates, etc. Among them, the electric weir gate controls the closing and opening size of the weir gate through the motor connected with the screw, which is popular because of its labor saving and high precision. However, there are still many problems in the use of the electric weir gate: 1. Control It is more complicated, and the execution speed is generally slow. When the weir gate is used to control the water level, instantaneous operation is often required. However, due to the long rotation time of the screw pitch when the lead screw is working, it cannot drive the weir gate in...

Problems solved by technology

Among them, the electric weir gate controls the closing and opening size of the weir gate through the motor connected with the screw, which is popular because of its labor saving and high precision. However, there are still many problems in the use of the electric weir gate: 1. Control It is more complicated, and the execution speed is generally slow. When the weir gate is used to control the water level, instantaneous operation is often required. However, due to the long rotation time of the screw pitch when the lead screw is working, it cannot drive the weir gate instantaneously, and cannot guarantee that when the water volume changes drastically. Requirements for water level control; 2. The motor and lead screw need to be checked frequently and lubricated for maintenance, otherwise the nuts will often get stuck or the motor case will be overheated, resulting in shutdown, and there are major safety hazards; 3 , Due to the working environment, coupled with seasonal changes and other factors, dust and sundries are inevitably generated inside and around the motor, which not only reduces the service life of the motor, but also reduces the operation accuracy of the weir gate, especially when working for a long time There will also be phenomena such as lead screw bending, which not only causes damage to components, increases operating costs, but also seriously affects the quality of work

The fixed weir occupies a large area, has a large head loss and high civil construction costs, and is not suitable for projects with small sites; there are problems such as flapping gates that are not tightly sealed when the flow is zero, and cannot maintain the liquid level for a long time.
