Abstract

Radial gate approach mechanism for prey. The present invention aims at a mechanism of approach of radial dam gate that allows a watertight seal of the gate without wear of the gaskets tightness and with a low coefficient of friction as it approaches only the gate panel to the outlet duct of water so that efforts are reduced, in addition to allow positioning of the board on the outlet duct of water prior to the operation of the mechanism of approach.

Description

Radial gate approach mechanism for prey.

Object pe the invention

The present invention aims at a radial gate approach mechanism for prey that allows make a tight seal of the gate without wear of the gaskets with a low coefficient of friction.

Due to its special configuration, the mechanism of approach of radial gate for dam approaches only the gate board to the water outlet duct of so that efforts are reduced.

Likewise, the gate presents a mechanism of drive that allows the board to be positioned on the duct water outlet prior to the actuation of the mechanism of approach.

Background of the invention

They are known in the state of the art the radial displacement mechanisms for closing dampers of dams that use seals in the closing zone.

Likewise, the mechanisms of radial gate approach to surface spillways or to bottom drains using a radial displacement mechanism in which once the gate has been faced with the water outlet, is displaced radially until the joints of tightness seal the outlet.

Among the above is the request Spanish Patent No. 200502031 referred to a radial gate for dam that pivots around an axis of rotation and where the mechanism of radial displacement has an eccentric axis with respect to the axis of turn of the gate that approaches or moves it away from the joints on the that adjusts.

In the previous mechanism, it must move radially the entire gate so that the closing of the joints on the perimeter of the water outlet duct.

This displacement is driven by a cylinder oleohydraúlico located next to the axis of rotation of the gate, of way you should move the gate arm from a point far away from the water outlet duct, so that the static friction that the cylinder must overcome until it starts the movement is very high, which implies high actuation pressures of the oil-hydraulic cylinder.

All these inconveniences are overcome by the invention that is now described.

Description of the invention

The present invention relates to a system of approach of radial dam gate that allows a watertight seal of the gate without wear of the gaskets tightness present in both the water outlet duct and on the gate board itself which also implies a bass coefficient of friction.

The gate presents a mechanism of drive that allows the board to be positioned on the duct water outlet prior to the actuation of the mechanism of approach that allows the sealing of the gate.

The gate panel is articulated with respect to its arm, so that the mechanism of approach of the radial dam gate, fixed by joints both to the gate arm and the board of the same, allows to move the board with respect to the arm until the gaskets come into contact with the outlet duct of the water.

This approach mechanism entails only the movement of the gate board, and not of all the together, so efforts are reduced.

Preferred Embodiment of the Invention

In view of the foregoing, the The present invention relates to an approach mechanism of radial dam gate that only brings the board of the gate to the water outlet duct so that the efforts are reduced.

The gate (1) has a mechanism (2) for drive, which in this preferred embodiment are drive cylinders that allow positioning the board (1.1) of the gate (1) over the water outlet duct (3) prior to the operation of the approach mechanism (4) due to which the gate (1) revolves around an axis of rotation present in arms (1.2) thereof (1).

The cylinder of the drive mechanism (2) It is articulated by its ends, both in the gate (1) and in a fixed element (5) outside the gate (1) and allows facing the same (1) with the water outlet duct (3).

The approach mechanism (4) consists of one or several articulated cylinders at its ends, both in the arms (1.2) of the gate (1) as on the board (1.1).

Also, the board (1.1) of the gate (1) It is articulated with respect to the arms (1.2) of the same (1) by a pivot shaft (1.3), so that the mechanism (4) of approach allows to move the board (1.1) with respect to the arms (1.2) until seals (1.1.1) are present at the edge of the board (1.1) come into contact with other joints (3.1) of tightness present at the ends of the duct (3) of Water.

They do not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient this one to proceed to its reproduction by an expert.

Claims (3)

1. Mechanism of approach of radial gate for dam between which they present / display a mechanism of operation (2) that allows to position the board (1.1) of the gate (1) on the conduit (3) of exit of water before the action of the approach mechanism (4) characterized in that it consists of one or more articulated cylinders at its ends, both in some arms (1.2) of the gate (1) and in the board (1.1), so that the board (1.1) of the gate (1), articulated with respect to the arms (1.2) thereof (1) by means of a pivot axis (1.3), is displaced with respect to the arms (1.2) until the seal between the board (1.1) occurs ) and the water line (3). 2. Radial gate approach mechanism for dam according to claim 1 characterized in that the seal occurs when seals (1.1.1) present at the edge of the board (1.1) come into contact with other seals (3.1) present at the ends of the water pipe (3). 3. Radial gate approach mechanism for dam according to claim 1 characterized in that the actuation mechanism (2) is a cylinder that is articulated at its ends, both in the gate (1) and in a fixed element (5) outside the gate (1).
