Problems solved by technology

However, despite this, it is still necessary to install an additional steel plate at the lower part of the sluice, or fill the interior with steel blocks to increase the self-weight of the sluice
This will inevitably lead to an increase in manufacturing costs

Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals are used to designate the same parts throughout the figures.

[0043] figure 1 The streamlined automatic opening / closing water gate 2 of the present invention is shown. A pair of pivot shafts 4 are formed on both sides of the upper part of the water gate 2, so that the water gate can be pivotally opened.

[0044] The upper portion of the water gate 2 has a streamlined portion 2a, thereby reducing resistance to water. The bottom of the sluice 2 has a curved portion 6, which can be in close contact with the bottom of the waterway to prevent water leakage and can withstand the pressure of the water.

[0045] There is a slightly arc-shaped portion 7 at the bottom of the curved portion 6, thereby reducing the water pressure and facilitating the lifting of the water gate.

[0046] figure 2 and image 3 The shown streamlined automatic opening / ...

Abstract

An automatically opening-closing streamlined water gate install in river for storage of water is characterized by that the liquid can be filled in it for regulating its dead weight, it can be automatically closed or opened by water pressure according to standard water level, and a lifting mechanism is installed for forced drainage.

Description

technical field [0001] The present invention relates to a sluice, in particular to a streamlined automatic opening-closing sluice, wherein the streamlined sluice can reduce the resistance to the water, and the self-weight of the sluice can be adjusted, according to whether it is lower than the standard water level, use The water pressure automatically opens or closes the sluice, and a vertical lifting mechanism for forced lifting of the sluice is installed so that the water can be discharged even at non-standard water levels. Background technique [0002] A typical facility for water management is a concrete structure installed in rivers, reservoirs and irrigation canals. Such a concrete structure facility is especially an important agricultural facility for supplying water to farmland. [0003] Conventional concrete structures of rivers, reservoirs and irrigation ditches are as follows, that is, a plurality of concrete members are installed in a direction perpendicular to ...
