Four positioning through holes are designed on the horizontal hoisting flange, the nested sonar test hoisting structure is installed at the lower end of a hoisting rod of the test system through the positioning through holes, and the distance between the axis of the hoisting rod and the center of a circle of the four positioning through holes is equal to the distance between the axis of the hoisting rod and the intersection point of the horizontal hoisting flange;
the horizontal hoisting flange is provided with cable through holes, so that ropes, cables and the like can conveniently pass through the horizontal hoisting flange without influencing test installation;
the vertical nested sonar mounting flange is embedded in a positioning groove at one end of a horizontal hoisting flange, the two flanges are mutually vertical and are reinforced and connected by two triangular reinforcing ribs, and the axis of a hoisting rod of the test system is ensured to be coincident with the sonar radiation surface to be tested;
the lower extreme of vertical nested sonar mounting flange be equipped with a pair of frame, enclose into the opening frame of an opening orientation, the opening frame be nested structure promptly, the both sides of a pair of frame all are equipped with sonar installation positioning hole, the sonar that awaits measuring of being convenient for is dismantled and is installed from both sides or nested structure's lower extreme, the sonar cable is also convenient for pass through.
Vertical nested sonar mounting flange can be from two orientations in the past back fixed mounting sonar that awaits measuring, realize multi-functional sonar test.
The invention has the beneficial effects that:
(1) simple structure, sturdy and durable. The invention only adopts two mutually perpendicular connected flange plates of a horizontal hoisting flange and a vertical nested sonar mounting flange, and realizes the sonar test hoisting function with a simple structure; meanwhile, the design of the positioning groove at one end of the horizontal hoisting flange ensures that the two flanges are vertically and stably butted, and particularly, the design of two triangular reinforcing ribs is adopted, so that the structure of the invention is firmer, and the requirement of sonar hoisting test on the structural stability can be completely met;
(2) the use and the disassembly and the assembly are convenient. The whole structure can be installed with a hoisting rod of a test system only through four positioning through holes on the horizontal hoisting flange; an open nesting structure is designed at one end of the vertical nesting sonar mounting flange, the sonar to be tested can be conveniently butted and mounted or dismounted from two sides or an opening, and the problem of unchanged operation caused by the fact that a sonar cable penetrates through a hole in the middle of the mounting flange plate is solved to the greatest extent; in addition, some necessary cables, protection ropes and the like can conveniently penetrate through cable through holes designed on the horizontal hoisting flange during testing, so that the problems of winding and the like of the cables to a sonar to be tested in the testing process are avoided, and the hoisting structure is more convenient and flexible to use;
(3) has good versatility. Vertical nested sonar mounting flange nested formula hoisting structure is left and right, all symmetry around, convenient in the sonar that awaits measuring of two orientations installation from the front and back to multiple test function can be realized. For the sonar directivity test, in order to ensure the accuracy of the directivity test, the axis of a hoisting rod of the test system must be required to pass through the geometric center of a sonar radiation surface, and the installation of the sonar radiation surface under the horizontal hoisting flange is called backward installation; for testing of sound source level and axial sound pressure, reverse installation opposite to directivity testing can be adopted for forward installation, so that the sonar radiation surface is farthest from the horizontal distance of a hoisting rod of the testing system, the influence of the hoisting rod on space occupation of testing equipment such as hydrophones in a sound field is avoided, unnecessary interference of a testing hoisting structure on the sonar radiation sound field is avoided to the greatest extent, and the testing accuracy is ensured. The horizontal hoisting flange can be vertically installed, so that a sonar radiating surface is vertical to the water bottom or the water surface to develop various sonar detection researches and the like.
