The first-level connecting piece (35) is fixedly connected to the other end of the high-pressure medium storage and release compartment (2); the electromagnetic lock (32) is connected to the electromagnetic lock fixing hole (312) through the lock buckle (314); when the electromagnetic lock (32) receives a signal from the flight control device in the flight control system compartment (4), the electromagnetic lock (32) is separated from the electromagnetic lock fixing hole (312) by releasing the lock buckle (314), thereby separating the first-level connecting piece (35) from the electromagnetic lock fixing seat (31).

9. The self-inflating wing water rocket according to claim 8, characterized in that: The electromagnetic lock fixing seat (31) is provided with a spring column (313), and a spring is sleeved on the spring column (313). One end of the primary connecting member (35) is also provided with a spring sleeve (315). One end of the spring column (313) is fixedly connected to the electromagnetic lock fixing seat (31), and the other end of the spring column (313) and the spring extend into the spring sleeve (315); when the primary connecting member (35) is connected to the electromagnetic lock fixing seat (31) through the electromagnetic lock (32), the spring is compressed in the spring sleeve (315); when the primary connecting member (35) is separated from the electromagnetic lock fixing seat (31), the spring column (313) is pushed out of the spring sleeve (315) by the action force of the spring, so that the primary connecting member (35) is completely separated from the electromagnetic lock fixing seat (31).

10. The self-inflating wing water rocket according to claim 1, characterized in that: The other end of the water storage compartment (1) is provided with a nozzle (8), and the outer side wall of the water storage compartment (1) is provided with a first-stage fixed wing (7) along its circumference; the lower end of the water storage compartment (1) is connected to the nozzle (8) through a through hole, and when the high-pressure medium storage and release compartment (2) receives a control signal, it releases high-pressure gas; the high-pressure gas enters the water storage compartment (1), thereby squeezing the working medium in the water storage compartment (1) through the nozzle (8).
