The invention provides a device for multi-angle visual measurement of a seepage effect of a rock fracture blocked by magnetic mortar. A fracture space simulation device used for simulating the rock fracture is mounted at the top of a fixing device in a supporting manner; the crack space simulation device is connected with a water tank for injecting water through a water injection guide pipe, and the water tank is connected with a pressurizing device; a camera for monitoring the whole test process is arranged on the side edge of the crack space simulation device; the magnetic mortar is used for blocking the crack of the crack space simulation device; the micro grouting head is used for filling cracks of the crack space simulation device with magnetic mortar; the magnetic rod is used for guiding magnetic mortar in the grouting process; the ultrasonic flowmeter sensor is installed behind the magnetic bar and used for measuring the water flow rate after being blocked by the magnetic mortar.
