Description

Pulley block water conservancy gate

Technical Field

The utility model relates to a hydraulic equipment technical field particularly, relates to an assembly pulley water conservancy floodgate.

Background

The gate is used for closing and opening the control facility of the drainage (discharging) water channel. The important components of hydraulic buildings can be used for intercepting water flow, controlling water level, regulating flow, discharging silt and floating objects and the like. (1) Dividing according to the manufacturing materials. The gate mainly comprises a wooden gate, a wooden panel steel framework gate, a cast iron gate, a reinforced concrete gate and a steel gate. (2) The position of the gate top relative to the horizontal plane is divided. There are mainly open-top type gates and submerged type gates. (3) Divided by the nature of the job. Mainly comprises a working gate, an accident gate and an overhaul gate. (4) The method is divided according to the opening and closing method of the gate. The gate is opened and closed by mechanical operation and the hydraulic automatic gate is opened and closed by the change of water pressure borne by the gate when the water level rises and falls. (5) Divided into different supporting forms of the door leaf. Mainly comprises a fixed wheel supporting gate, a hinged supporting gate, a gate supported by a slideway, a chain wheel gate, a string roller gate, a round roller gate and the like.

When the form of the gate is selected, the gate needs to be determined by comparing the technical economy according to the working property, the setting position, the operating condition, the span of a gate hole, the opening and closing force, the engineering cost and the like of the gate and by combining the characteristics of the gate and referring to the existing operating practical experience. Of which the flat gate and the radial gate are the most commonly used gate shapes. The large, medium-sized exposed top and submerged working gates are mostly arc gates, and the high-head deep-hole working gate is particularly commonly used as the arc gate. When used as an accident gate and a maintenance gate, a flat gate is mostly used. An overhaul gate and an accident gate are often arranged in front of the working gate. For the high-head water discharge working gate, because the working gate is operated by frequently operating water or is partially opened, the phenomena of gate vibration and cavitation erosion are reduced, the hydraulic condition of the gate is improved, the influence of power is considered according to different parts, and the rigidity and the power characteristics of the gate body are analyzed and researched. The manufacturing and mounting precision of the door leaf and the embedded part should be strictly controlled, when the boundary flow state of the door slot is complex or the body shape is special, besides the prior successful test, the problems of vibration and cavitation corrosion which may occur are solved through a hydraulic model test so as to select the proper body shape of the door slot. The traditional water conservancy gate can be started only by using high-power instruments such as a motor and the like, and is troublesome and wastes resources.
