The invention discloses a built-in pump spraying type underwater vehicle which comprises a shell, a storage bin arranged at the head of the shell and a main propelling mechanism arranged at the tail of the shell, detection equipment and a storage battery pack are stored in the storage bin, a water inlet is formed between the front end of the main propelling mechanism and the tail of the storage bin, and a water spraying opening is formed in the rear end of the main propelling mechanism. A pump spraying type propeller is arranged in the main propelling mechanism, water flow enters from a water inlet, penetrates through the main propelling mechanism and then is sprayed out from a water spraying opening, and two small auxiliary propellers are symmetrically arranged at the positions close to the tail machine shell. The invention relates to a novel combined propelling method and a propeller structure, a built-in pump spraying structure enables the system noise to be low, the thrust can be greatly increased in a sh
