Abstract
A control gate is adapted to be installed across a channel for liquids. The Control gate has a barrier member capable of vertical or tilting movement and it is either slidingly or pivotally mounted to a frame of the control gate. In one instance, the control gate has at least one side member attached to the barrier member. A drive member co-operates with the side member(s) to allow raising and lowering of the barrier member to regulate flow of liquid through the control gate. The drive member includes a spool and an engagement member that is secured under tension and winds around the spool. As the spool turns it causes, with the engagement member, movement of the barrier member. Also described is a method of measuring flow rate through a control gate.
Claims30
A control gate adapted to be installed across a channel for liquids, the control gate comprising:
- a barrier member with a sidemember that has a circular arcuate section, the barrier member being pivotally mounted at or adjacent to the base of the channel;
- and
- a drive cooperating with the side member for raising and lowering the barrier member to regulate flow of liquid through the control gate, the drive including a cable and a winding spool, the cable being looped at least once around the winding spool and on each side of the winding spool the cable is respectively secured to opposite ends of the circular arcuate section under tension with the winding spool being adjacent to the circular arcuate section in order to maintain the cable in a substantially peripheral contact with the circular arcuate section when the winding spool cooperates with the cable along the circular arcuate section for transferring rotary motion of the winding spool into motion of the side member.
A control gate, comprising:
- a barrier member;
- a moving device for controlling movement of the barrier member, the moving device including a drive member and an engagement member running a length or a side of the barrier member, the drive member cooperating with the engagement member to cause movement of the barrier member on rotation of the drive member, the engagement member being looped under tension at least once around the drive member and on the opposing sides of the drive member the engagement member is respectively secured to opposite ends of the barrier member under tension with the drive member being adjacent to the barrier member to maintain the engagement member in a substantially peripheral contact with the barrier member when the drive member cooperates with the engagement member for transferring rotary motion of the drive member into motion of the barrier member.
A control gate, comprising:
- a barrier member configured for vertical or tilting movement;
- and
- a moving device for controlling movement of the barrier member, the moving device including a winding spool and an engagement member running a length or a side of the barrier member, the winding spool cooperating with the engagement member to cause movement of the barrier member, the engagement member being looped at least once around the winding spool and secured to opposite ends of the barrier member under tension with the winding spool positioned adjacent to the barrier member to maintain the engagement member in substantial contact with the barrier member when the winding spool cooperates with the engagement member for transferring rotary motion of the winding spool into the vertical or tilting motion of the barrier member.
A method for controlling flow of liquid through a gate in a channel, comprising:
- mounting a barrier member at or adjacent to a base of a channel;
- providing a drive member for controlling movement of the barrier member to regulate flow of liquid in the channel;
- looping an engagement member at least once around the drive member;
- and
- on the opposing sides of the drive member, respectively, securing the engagement member to opposite ends of the barrier member under tension with the drive member being adjacent to the barrier member to maintain the engagement member in a substantially peripheral contact with the barrier member when the drive member cooperates with the engagement member for transferring rotary motion of the drive member into motion of the barrier member.
