Abstract

An oil-pressure-type water gate includes a gate panel and a lifting mechanism. The lifting mechanism consists of an oil pressure cylinder having a rod used for moving a crank. Then the crank drives the shaft of two rotatable rollers, and two ropes are provided to extend around the rotatable rollers and plural stationary rollers, having their one ends fixed with two opposite sides of an upper end surface of the gate panel. When the lifting mechanism is operated, the two ropes are wound and pulled to lift up or lower down the gate panel to open or shut the gate for adjusting the water level.

The upper and lower gates 5 and 6 are each provided with a pulley 10 to keep the sluice gate lifting smoothly. The upper and lower gates 5 and 6 are formed by a two-piece design. The upper and lower gates 5 and 6 and the joint surfaces 50 and 60 of the upper and lower gates are inclined surfaces. Such joint surfaces 50 and 60 Its advantage is that when the upper gate 5 first rises a distance, the water in contact with the upper gate can flow out first, and the water pressure above it can be removed first, which can reduce the water pressure imposed on the gate, and between the upper gate 5 and the lower gate 6 The lifting link 5 1 with a little support is arranged in an I-shape, which can be fixedly connected or movable with the upper gate. After the upper gate rises a distance, It can abut against the inner surface of the top wall of the connecting rod groove 61 of the lower gate 6, and the upper gate 5 can drive the lower gate to rise to achieve the function of opening the upper and lower gates in stages. This kind of driving the upper gate first and then the lower gate not only has the initial labor-saving function, but also saves water (if the gate is only half-opened), it can also reduce the pressure of the pressure on the gate, making the water gate more practical. , And it's time to go up the gate

Driven by the oil circuit, the telescopic operation of its cylinder shaft , So that the second-moving pulley can be raised and lowered, and the sluice gate can be raised and lowered. 2 · According to the hydraulic water gate machine (3) shown in item 1 of the scope of patent application, the water gate adopts the two-piece structure design of the upper and lower gates. 3. The hydraulic water gate machine (3) shown in item 1 of the scope of the patent application, in which a certain pulley is arranged in the concrete structure, and a support shaft is arranged below the water gate, so that the water gate has a tilting structure. Practical design. 第12頁Page 12
