Problems solved by technology

[0002] There are generally two methods for calculating the opening of arc gates. One method is to use segmented broken lines (the number of broken line segments is different according to the setting of different gate openings). The gate opening is the 15-segment broken line used. In each segment of the broken line, the method of fitting a straight line is used to calculate the gate opening. Accurate professional measuring instruments are required to measure the inflection point value of each broken line, and a lot of data needs to be measured. Lifting the

Example Embodiment

[0042] In order to facilitate understanding of the invention, the invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is considered to be "communicating" with another element, it can be in direct communication with the other element or intervening elements may also be present.

[0044] For the convenience of description, "left", "right", "up" and "down" in the following are consistent with the left, right, up and down dire...

Abstract

A radial gate opening degree calculation method comprises the following steps that step S1, a circle O2 is made with the fulcrum as the center and the length of a lifting rope as the radius R2; step S2, a circle O1 is made with the supporting hinge as the center and the length of the supporting arm as the radius R1; step S3, a rectangular plane coordinate system Oxy is established with the supporting hinge as the original point; step S4, the circle center coordinate of O1 is set as (0, 0), the circle center coordinate of O2 is set as (x0, y0), x0 is the horizontal distance from the fulcrum tothe supporting hinge, and y0 is the vertical distance from the fulcrum to the supporting hinge; step S5, the circle O1 and the circle O2 are intersected at two points p and q, wherein the position where the point p is located is a lifting point; step S6, the angle value of the point p on the circle O1 is set to be alfa, wherein the angle pos is beta; step S7, the distance between the supporting hinge and the s point at the bottom of the arc-shaped gate leaf is set to be R3; step S8: R1, R2, R3, x0 and y0 can be measured by a tape; and step S9, solving an s point coordinate value. Real-time, rapid, accurate and convenient data calculation is adopted, and the data measurement difficulty is reduced as much as possible.

Description

technical field [0001] The invention relates to a method for calculating the opening of a flood gate of a hydroelectric power plant, in particular to a method for calculating the opening of an arc-shaped gate. Background technique [0002] There are generally two methods for calculating the opening of arc gates. One method is to use segmented broken lines (the number of broken line segments is different according to the setting of different gate openings). The gate opening is the 15-segment broken line used. In each segment of the broken line, the method of fitting a straight line is used to calculate the gate opening. Accurate professional measuring instruments are required to measure the inflection point value of each broken line, and a lot of data needs to be measured. Lifting the gate to each set inflection point of the polyline in turn is cumbersome in both measurement and operation. The accuracy of this algorithm is not high enough, and data jumps may occur at the infl...
