Abstract
The present invention relates to a kind of water resistance and specialize in pole plate, comprise three groups of water resistance pole plates, be respectively the large pole plate of A group water resistance, the large pole plate of B group water resistance and the little pole plate of C group water resistance, wherein the large pole plate of A group water resistance is identical with the load of the large pole plate of B group water resistance, the load of the little pole plate of C group water resistance is the half of the load of the large pole plate of A group water resistance, the large pole plate of A group water resistance is pentagonal configuration, the large pole plate of B group water resistance is identical with A group water resistance large pole plate shape, the little pole plate of C group water resistance is triangular in shape, three groups of water resistance pole plates are installed at grade, and often the angle organized between water resistance pole plate is 120 °.The invention has the advantages that: by the combination in any of three groups of pole plates, under ensureing various load state, adjustable range is all in effective travel.
Description
Technical field
The present invention relates to a kind of special polar plate for water resistance, especially one regulates water resistance pole plate eaily when little load.
Background technology
Water resistance pole plate in current use is two groups of uses in parallel, in use there is the rated value in order to ensure total load, when little load, regulating more difficult.
Summary of the invention
Technology body to be solved by this invention is to provide one and regulates water resistance pole plate eaily when little load.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of special polar plate for water resistance, and its innovative point is: comprise three groups of water resistance pole plates, is respectively the large pole plate of A group water resistance, the large pole plate of B group water resistance and the little pole plate of C group water resistance;
Wherein the large pole plate of A group water resistance is identical with the load of the large pole plate of B group water resistance, the load of the little pole plate of C group water resistance is the half of the load of the large pole plate of A group water resistance, the large pole plate of A group water resistance is pentagonal configuration, and wherein there are three angles to be right angle, the large pole plate of B group water resistance is identical with A group water resistance large pole plate shape, the little pole plate of C group water resistance is triangular in shape, the little pole plate of the large pole plate of A group water resistance, the large pole plate of B group water resistance and C group water resistance is installed at grade, and often the angle organized between water resistance pole plate is 120 °.
The invention has the advantages that: three groups of loads can be combined by any switching laws by three switches, when little loaded work piece, drop into little pole group, make adjustable range substantially constant, by the combination in any of three groups of pole plates, under ensureing various load state, adjustable range is all in effective travel.
