Problems solved by technology
[0003] When the gate moves to the required water blocking height, it should be able to stay at the required position reliably for a long time when the power is cut off. Although the driving cylinder can be locked by hydraulic lock and other components, the hydraulic lock is affected by the internal and external leakage of the cylinder. , after the power source is cut off, the long-term locking is not reliable, so the locking problem of the gate is related to the safety and reliability of the operation of the sluice

Embodiment Construction
[0012] Further illustrate the present invention in conjunction with accompanying drawing and embodiment, as figure 1 , figure 2 , image 3 As shown, the present invention uses a locking cylinder 16 as an actuator to drive the locking pin 10 fastened on its piston rod to move back and forth, so as to realize the locking and unlocking actions of the steel gate.
[0013] image 3 It is the unlocked state when the gate releases water. When the swing gate needs to block water, the hydraulic device 8 of the driving cylinder is energized to run, so that the piston rod of the driving cylinder 5 installed on the cylinder bracket 7 is retracted to the right, thereby driving the crank arm 3 Swing clockwise along the central point of the hinge seat 1 on the bottom shaft, so that the steel gate 2 fixed on the bottom shaft gradually swings clockwise along the center of the bottom shaft from the horizontal direction. When the steel gate moves to a certain required height, and the locking...

The invention relates to a locking device of a steel gate, belonging to the technical field of the capital construction of water conservancy and hydroelectric power gate projects. After corresponding electricity controllers are arranged, the locking device can be automatically controlled and transformed in the states of a locking work condition and an unlocking work condition by arranging a vertical pulling locking rod and a locking pin which is driven by a locking cylinder; the steel gate integrally connected with a connecting lever is locked in a needed height; after a power source is cut off, the steel gate can also be reliably kept in a locking state for a long time. When in work, the locking rod suffers pull and pressure without twisting force basically. The invention has the advantages of small volume, simple structure, convenient installation and adjustment, low investment and cost and convenient maintenance; matched with electricity automatic control, the locking device can becontrolled remotely, thereby persons who are on duty in gate control rooms can be none or a few. The locking device of the steel gate is applied to city water way reconstruction, environment protection, pollution treatment and popularization in water conservancy and hydroelectric power construction projects.
Description
technical field [0001] The invention relates to a locking device for a steel gate, which belongs to the technical field of infrastructure construction of water conservancy and hydropower gate projects. Background technique [0002] Water conservancy and hydropower are infrastructure related to the national economy and the people's livelihood. With the increasing demand for urban water use, landscape construction, environmental improvement, irrigation, and power generation in my country, various water conservancy gates have been widely used. The steel gate in the gate is called steel dam gate or bottom horizontal axis flip gate. This kind of steel gate has many advantages, such as adapting to wide river channels, simple structure, reducing intermediate gate piers, saving civil construction investment, and can be closed. Water storage, opening of gates for flood drainage, and the use of gate tops to pass water to form the landscape effect of artificial waterfalls, and the abil...
