The invention discloses a water gate manual opener. The water gate manual opener structurally comprises a hand rocker, a shaft head tube, a screw rod, a shell, a support, a base plate, a power assisted device, an opener main body and a gear, the support is T-shaped and divided into two parts, the upper part of the support is a cuboid, the lower part of the support is in a parallelogram shape, thebutt joint of both ends of the support are connected by welding in an attached mode, the surface of the bottom of the shell is welded to the center of the top surface of the support in an attached mode, the shell is T-shaped, and the surface of the inner side of the support is in clearance fit with the center of the outer side surface of the screw rod. According to the water gate manual opener, the power assisted device is arranged on the water gate manual opener, during shaking of the hand rocker, and an inner ring is attached to the hand rocker to rotate to drive the balls on a limiting ringto rotate, so that the balls in an outer ring and the inner ring drives the main body of the power assisted device to assisting power during shaking of the hand rocker through the inner ring, the hand rocker drives the opener main body to rotate with less effort accordingly, laborious opening of the manual opener is avoided, and the working efficiency of the manual opener is effectively improved.
本发明公开了一种水利闸门手动开启器，其结构包括手摇杆、轴头管、螺杆、外壳、支座、底板、助力装置、开启器主体、齿轮，所述支座呈“T”字型，分为上下两部分，上部为长方体，下部为“口”字型，两端对接处通过焊接贴合连接，所述外壳底部表面贴合焊接在支座顶部表面中央，外壳呈“T”型，所述支座内侧表面间隙配合螺杆外侧表面中央。本发明设有助力装置，手摇杆摇动时，内圈贴合在手摇杆转动带动限位圈上的滚珠转动，使滚珠在外圈和内圈内带动助力器主体经内圈对手摇杆摇动时助力，使手摇杆带动开启器主体转动较省力，避免手动开启器开启时费力，有效提高手动开启器的工作效率。
