随着各种闸门的不时呈现，近程控制执行机构的运用越来越普遍，启闭机通常使用在各类大型给排水及水利水电工程中，用于控制各类大、中型铸铁闸门及钢制闸门的升降到达开启与封闭的目的，也称之爲闸门操作设备。

现有技术地下了请求号爲的一种螺杆式启闭机，包括切换安装，切换安装内开有沉孔，沉孔呈矩形构造，沉孔与切换安装之间衔接有向心球轴承，向心球轴承机械衔接在沉孔与切换安装之间，切换安装下外表装置有操纵杆，操纵杆爲两个，两操纵杆底部位于一传动杆上，传动杆上开有与操纵杆婚配的通孔，传动杆下外表装置有齿轮座，齿轮座与传动杆之间经过密封安装衔接，齿轮座底部设有齿轮条，齿轮条内装置有齿轮轴，齿轮座及齿轮条外侧装置有气动执行器，气动执行器可装配衔接在齿轮座及齿轮条上，气动执行器内装置有转向杆，转向杆采用工字型构造。但是其缺乏之处在于手动螺杆式启闭机存在休息强度大，启闭不灵敏。With the emergence of various gates from time to time, the use of short-range control actuators is becoming more and more common. Hoists are usually used in various large-scale water supply and drainage and water conservancy and hydropower projects to control the lifting and closing of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing, also known as gate operation equipment. A screw hoist with the request number 201410538872.3 underground includes switching installation, switching installation with sinking holes, rectangular structure of sinking holes, connection of sinking holes and switching installation with centripetal ball bearings, mechanical connection between sinking holes and switching installation, switching installation with external device with control rods, two control rods at the bottom of the two control rods. Located on a transmission rod, the transmission rod is provided with a through hole matched with the control rod, the outer device of the transmission rod is provided with a gear seat, the gear seat and the transmission rod are sealed and connected, the bottom of the gear seat is provided with a gear rack, the inner device of the gear rack has a gear shaft, the outer device of the gear seat and the gear rack has a pneumatic actuator, and the pneumatic actuator can be assembled and connected to the gear seat and the gear rack. A steering rod is installed in the dynamic actuator, and the steering rod is constructed with I-shaped structure. But its shortage is that the manual screw hoist has strong rest intensity and insensitive opening and closing.

 暗杆式螺杆启闭机，包括机座、机箱、设置于机箱内的蜗轮蜗杆组件、提供动力的电动机、与涡轮固接一同的螺杆，以及与螺杆构成螺纹配合的吊耳螺母，螺杆经过衔接套、中心主轴、键与涡轮衔接爲一体，螺杆、涡轮、中心主轴同心设置；吊耳螺母设置在闸门门顶上、并用螺栓与闸门紧固。本适用新型可准确测定、显示、控制启闭机启闭闸门的开度信息，完成闸门自动控制，进步工程防洪、灌溉、发电的调度指挥效益和程度，完成了水利工程古代化管理，同时，本适用新型还具有构造复杂、举措灵敏、平安牢靠、运用方便等优点。The concealed screw hoist includes the base, the chassis, the worm gear and worm assembly set in the chassis, the power supply motor, the screw fixed with the turbine, and the lug nut with the screw thread matching. The screw is connected with the turbine through the connecting sleeve, the central spindle, the key and the turbine as a whole. The screw, the turbine and the central spindle are concentrically arranged; the lug nut is arranged at the gate gate. Tighten the gate with bolts on top. The new type can accurately measure, display and control the opening information of the hoist gate, complete the automatic control of the gate, improve the efficiency and degree of flood control, irrigation and power generation dispatch, and complete the ancient management of water conservancy projects. At the same time, the new type of application has the advantages of complex structure, sensitive action, safe and reliable, and convenient operation.
