Description
Technical Field
The invention belongs to the technical field of immersion experiments, and particularly relates to a method for eliminating buoyancy of a box body in an immersion experiment and a sealing device.
Background
The box-type substation requires the box body skeleton to be an integral welding structure during design, the skeleton is welded by profile steel, the skeleton has enough mechanical strength and rigidity, the skeleton cannot be deformed or damaged during hoisting, transportation and installation, the protection grade of the shell meets data in a parameter table, the shell is waterproof, shockproof, anticorrosive, dustproof, fireproof and flame-proof, the protection grade of the shell is not lower than IP54 in GB4208, and the protection grade of the current shell may also require IP68.
The traditional seal box adopts the following mode when carrying out the immersion test: the box is directly placed in the pool, and then water is gradually injected into the pool to enable the water to overflow the top of the box, so that the purpose of the test is achieved. This test method has the following problems: first, traditional pond receives the limitation of factory building overall arrangement, builds the corner at the factory building usually, and the degree of depth of pond has been fixed when the preparation, and if the height of product is less than the pond height far away, the fixed difficulty of product crimping, if the product height is higher than the pond, then can't test, will make the pond again. Second, when filling water into the pool, the case can produce buoyancy, and as the water level rises gradually, the buoyancy produced is bigger and bigger. Therefore, the compression joint beam is additionally arranged at the top of the water tank required by the traditional water testing mode, the sealing box is prevented from floating upwards, and the purpose of water testing is achieved. According to the calculation mode of buoyancy, the buoyancy that the sealed box received is directly proportional with its volume itself, and traditional sealed box volume all is comparatively huge, so at experimental in-process, the crimping roof beam at pond top receives huge jacking force always, lets the crimping roof beam have inefficacy, and whole roof beam bounce leads to the seal box also consequently to have lost the crimping, and whole case bounce has huge potential safety hazard. Thirdly, the test product is fixed in an anti-floating mode in a compression joint mode, and the buoyancy is totally concentrated at the position of a compression joint part, so that the product is subjected to huge pressure at the position, and local deformation and even damage can be caused to the product.
