Problems solved by technology

[0003] In the traditional screw gate with brake position detection, the encoder is placed on the top of the machine head, and the gear that meshes with the thread on the screw is installed on the drive shaft of the gate sensor. It has the following defects: the transmission structure is unstable, and sometimes the screw is bent. It is difficult to meet the requirements of automatic control due to accidents such as gate lifting and offside; the limit device and encoder are set independently, the gate position detection and limit control cannot be coordinated, the structure is loose, and installation and operation are very inconvenient; the cumulative error of gate position measurement Large, low measurement accuracy, resulting in inaccurate gate opening

Abstract

The invention provides a gate position measurement and control device of a screw gate and a gate control device, and belongs to the field of water conservancy projects. The gate position measurement and control device of the screw gate comprises a stroke gear, an intermediate shaft, an encoder and a first limiting device, wherein a shaft hole is formed in the center of the stroke gear, the intermediate shaft is matched with the shaft hole, and the intermediate shaft penetrates through the shaft hole to be fixedly connected with the stroke gear; the encoder is in transmission connection with the first end of the intermediate shaft; and the first limiting device is in transmission connection with the second end of the intermediate shaft. The gate control device comprises the gate position measurement and control device of the screw gate. The gate position measurement and control device of the screw gate has the function of integrating gate position measurement and limiting, and is more stable in structure.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a screw gate position measurement and control device and a gate control device. Background technique [0002] Screw gate, referred to as screw gate, is widely used in various engineering projects related to the water conservancy industry due to its simple structure, convenient installation and operation, and high cost performance. As one of the traditional hydraulic engineering infrastructures, the screw gate plays an important role in the field of smart water conservancy. In addition to meeting the needs of water conservancy supervision departments for water use, water management, and water control, it also plays a role in flood control, protection of industrial and agricultural production, and people's lives and property. Many aspects such as safety and environmental protection have played a huge positive role. The screw gate is mainly composed of hoist, screw, pow...
