Wellhead sealing device of dewatering well
The invention discloses a dewatering well mouth sealing device which comprises a supporting casing pipe, a sealing ring, a sealing ring and a sealing ring. A containing groove allowing an upper port of a dewatering well to be embedded is formed in the end face of the lower end of the supporting casing pipe, and the containing groove is arranged in a circle in the circumferential direction of the supporting casing pipe; the winding shaft is used for winding an electric wire of a draining pump in the dewatering well and is mounted in the supporting sleeve; the ball cover assembly comprises a fixed cover plate and a movable cover plate, the fixed cover plate and the movable cover plate are respectively in an arc shape and are coaxially arranged with the winding shaft, one side of the fixed cover plate is fixedly arranged on one side of the upper end opening of the supporting sleeve, and a fan-shaped notch is formed between the other side of the fixed cover plate and the other side of the upper end opening of the supporting sleeve; the movable cover plate is installed on the winding shaft in a turnover mode and shields the fan-shaped notch, and after the movable cover plate is turned over, the movable cover plate is embedded in the inner side of the fixed cover plate so as to open the fan-shaped notch. The problems that according to a conventional dewatering well sealing method, installation is not firm, and damage is prone to occurring are solved.
本发明公开了一种降水井井口封闭装置，包括：支承套管，其下端端面形成有供降水井的上端口嵌设的容置槽，容置槽沿支承套管的圆周方向设置一圈；供降水井内的排水泵的电线缠绕的绕线轴，安装于支承套管内；以及球罩组件，包括固定罩板和活动罩板，固定罩板和活动罩板分别呈弧形且与绕线轴同轴设置，固定罩板的一侧固设于支承套管的上端口的一侧，固定罩板的另一侧与支承套管的上端口的另一侧之间形成一扇形缺口，活动罩板可翻转地安装于绕线轴且遮蔽于扇形缺口，在翻转活动罩板后，活动罩板嵌设于固定罩板的内侧以开启扇形缺口。本发明解决了常规的降水井封闭方法存在安装不牢固、容易破损的问题。
