The invention discloses a drainage valve control device, and relates to the technical field of drainage control mechanisms, the drainage valve control device comprises a traction driving mechanism and a drainage sealing mechanism, the traction driving mechanism comprises a traction capstan, the traction capstan is fixedly connected with a traction rope ring, and the middle of the traction rope ring is fixedly connected with a traction block; the drainage sealing mechanism comprises a movable pipe, a water blocking sleeve is slidably installed in the middle of the movable pipe, and the inner wall of the water blocking sleeve is fixedly connected with a traction block through a connecting frame. A traction rope in a common drainage control device is replaced with a traction rope ring, structures such as a driving motor are used for driving a traction winch to rotate in a reciprocating mode, and the traction rope ring and a traction block on the traction rope ring are driven to rotate in a reciprocating mode, so that traction and pushing of the water blocking sleeve are achieved, and then movement and displacement of the water blocking sleeve are more controllable; the problem that the sealing performance is insufficient due to the fact that displacement of a control device with one-way traction matched with spring reset is not in place is effectively solved.
本发明公开了一种排水阀控制装置,涉及排水控制机构技术领域,包括牵引驱动机构和排水封闭机构,所述牵引驱动机构包括牵引绞盘,所述牵引绞盘上固定连接有牵引绳环,所述牵引绳环的中部固定连接有牵引块;所述排水封闭机构包括活动管,所述活动管的中部滑动安装有阻水套筒,所述阻水套筒的内壁通过连接架与牵引块固定连接;本发明通过将常见排水控制装置中的牵引绳替换为牵引绳环,利用驱动电机等结构带动牵引绞盘往复转动,带动牵引绳环以及其上的牵引块往复转动,实现对阻水套筒的牵引和推送,进而使得阻水套筒的运动移位更加可控,有效避免了单向牵引配合弹簧复位的控制装置所存在的移位不到位导致密封性不足的问题。
