Foot pedal type tri-body water jet boat

Abstract

The invention discloses a foot pedal type tri-body water jet boat. The foot pedal type tri-body water jet boat comprises a tri-body boat; the tri-body boat comprises a main hull and side bodies and aconnecting bridge; a water inlet cabin is arranged on the main hull; a water jet propelling device is arranged in the water inlet cabin; the water jet propelling device comprises a booster cylinder, aspray pipe and a multi-angle steering nozzle; the booster cylinder comprises a big cylinder body, a small cylinder body, a big piston, a small piston, a push rod, a telescopic spring and a pedal; thepush rod is connected with the small piston and the big piston and penetrates through the top of the big cylinder body; the pedal is mounted at the top of the push rod; a water inlet clearance is formed between the small piston and the small cylinder body; a telescopic spring is arranged between the small piston and the bottom of the small cylinder body; the bottom of the small cylinder body communicates with the multi-angle steering nozzle through the spray pipe; the multi-angle steering nozzle is mounted at the front part of the main hull; a water inlet pipe is arranged on the side surfaceof the big cylinder body; and a one-way valve is mounted on the water inlet pipe. According to the foot pedal type tri-body water jet boat, the tri-body boat can dynamically balance the attitude and possesses better shipping-direction stability. Meanwhile, by using a foot pedal type spraying mode, the operation is convenient, and a better experience effect is realized.

Description

technical field [0001] The invention relates to a boat, in particular to a foot-operated three-body water jet boat used for recreational activities on water. Background technique [0002] Most of the current water jetting entertainment uses this kind of water jet gun, which makes the activities subject to various restrictions; especially in water jetting activities, the pleasure boat and the water jetting device are not integrated and utilized, which greatly reduces the fun of entertainment. Simple spray pistol is made up of simple piston, hydraulic cylinder water pump and two one-way valves. Because the pump works by moving the trigger back and forth, this design is very limited in the size, range, and duration of the spray. A simple solution to this type of problem is to increase the size of the pump cylinder and trigger, which is the basic idea of ​​a traditional water bazooka. [0003] The trimaran is mainly composed of three hulls, the main hull in the middle, and an ...
