The invention provides a novel multifunctional water gate, relates to the field of water gates, and aims to solve the problems that when an existing novel water gate is used, the function is single, garbage floating in water cannot be collected, a garbage collecting structure cannot be moved according to needs, and use is inconvenient. The novel multifunctional water gate comprises a main body, the main body is of a T-shaped structure, a motor is installed in the middle of the main body, a round hole is formed in the middle of the main body, and a shaft rod of the motor is inserted to the interior of the round hole. After the novel multifunctional water gate is used for a long time, water flow impacts garbage and sundries in water to rush to the shore and the main body, when water drives the garbage to impact, the garbage can enter the interior of a collecting tank, and therefore an auxiliary block can assist in blocking the garbage, and the garbage can be effectively stored and collected; and when the gate is opened to drain water, a collecting piece can further filter the water, and therefore garbage can be blocked, fishes and shrimps can be intercepted, and aquatic products cannot be lost.
