Waterproof grade testing device with function of simulating different water depth pressures

The utility model belongs to the technical field of testing equipment, and particularly relates to a waterproof grade testing device with a function of simulating different water depth pressures, which comprises a tank cover, a tank body, a support, a gas booster pump and a controller, the tank cover is arranged above the tank body, the support is arranged below the tank body, and the gas booster pump is arranged in the tank body. According to the utility model, the pressure of different water depths is simulated in a gas injection pressurization mode, the pressurization speed is high, the time consumption of a pressure water immersion environment is reduced, and the test efficiency is improved. The separation net and the placing basket are arranged in the tank body, and equipment with lower density is blocked by the separation net, so that the situation that the equipment cannot be completely soaked due to floating on the water surface and the measurement result is influenced is avoided; and equipment with r
