The utility model discloses a device used for measuring ponding-resistant load performance of a sunshade comprising a test frame, a spraying device, and a control system. The spraying device comprises a spraying pipe, a water supply pipeline, and a water tank. The water tank can be used to provide sufficient clean water for the whole test process, and is disposed on the bottom part of the test frame. The water can be conveyed to the spraying pipe by the water supply pipeline. The test frame is provided with a test piece fixing device, and the tested sunshade is expanded, and is fixedly disposed on the test frame by the test piece fixing device. The test piece fixing device is disposed on the middle position of the test frame along the up-down direction, and then the spraying pipe can spray water downwards to the tested sunshade. The water supply pipeline is provided with an electromagnetic flowmeter used for measuring the water spraying flow, a shielding valve used for controlling the pouring of the water in the pipeline, and a gate valve used for adjusting the water flow.
