Backpack intelligent underwater human body propeller

Abstract

The invention discloses a backpack intelligent underwater human body propeller, which includes a main body shell, propelling devices, straps, an airbag, an emergency oxygen supplying bag, a head lamp,a camera, a control handle, an intelligent processor and a battery. The main body shell is internally provided with a cavity, the propelling devices are arranged on the two sides of the cavity in themain body shell, the straps are connected to the lower part of the main body shell and are bound to a human body, the airbag and the emergency oxygen supplying bag are arranged in the cavity in the main body shell and located on the outer sides of the propelling devices correspondingly, and the buoyancy and oxygen are provided for the human body through the airbag and the emergency oxygen supplying bag correspondingly; and the head lamp and the camera are both arranged on a front end shell of the main body shell, the control handle is connected with the main body shell through a control circuit, and the human body propeller is controlled through the control handle. According to the backpack intelligent underwater human body propeller, both hands can be freed, the intelligence and controllability are achieved, the functions are rich, control is flexible, the lightness and labor saving are achieved, the safety and reliability are achieved, design is reasonable, the diving difficulty isgreatly lowered, the multiple functions of the propeller are increased, the intelligence of the propeller is realized, the diving physical output is reduced, and the safe and reliable properties are improved.

Description

technical field [0001] The invention relates to the technical field of diving thrusters, in particular to a backpack-type intelligent underwater human body thruster. Background technique [0002] As an emerging tool to provide auxiliary propulsion for divers, underwater propulsion provides a new way of diving and improves the range and speed of people's activities in water. The existing underwater propeller mainly uses a battery as a power source, and drives a propeller through a driving motor to generate thrust to assist the human body to perform underwater movements. [0003] At present, there are many hand-held thrusters, and the binding types are different, such as binding the thrusters to the soles, heels, calves, thighs, chest, abdomen, back, waist, arms, etc. For example, the invention with the notification number CN206900616U provides an underwater propeller, which includes an intermediate battery compartment, a motor connected to the battery, and a propeller instal...

AI Technical Summary

Problems solved by technology

[0004] 1. Hands not liberated: When the handheld propeller is operated underwater, it must be held by hand, and the hands are restricted. The diving activities are not free enough, and it is impossible to balance propulsion and operation; 2. Single function: it only plays the role of underwater power propulsion. There are no functions such as detection, photography, lighting, navigation and positioning, signal transmission, hardware interconnection, etc. It is applicable to a single scene and cannot be applied in a wide range; 3. Inconvenient manipulation: because it only has the function of forward propulsion, the maneuverability is insufficient and it cannot be turned flexibly; the binding type It is difficult to guarantee the stability of underwater control when connecting with a Bluetooth bracelet. Once the connection is unsuccessful, it will bring danger to divers; 4. The power is unstable and inflexible: it is difficult to maintain balance (lack of intelligent hovering control system or buoyancy adjustment chamber, The buoyancy cannot be adjusted freely, and it cannot be applied to scenes that require underwater hovering), the power direction is uncontrollable (the power direction is easily affected due to many movements when the limbs are bound, and it is extremely unbalanced), the power output is unstable (there is no efficient power output processor), power cannot be infinitely variable (only switch or only one or two gears, no intelligent output control system), insufficient power (low speed, basically below 1.5m / s), short battery life (less than 1 hour) ;5. Too bulky and energy-intensive: generally half the size of a human body, and the weight is large, which is not easy to carry. In addition, it needs to be hand-held and cannot hover, which makes diving also require a lot of energy; 6. Lack of safety Protection: no airbag, radar avoidance system, quick release and other functions, in case of emergency, it is impossible to get out of danger in time; 7. Unreasonable design: the binding method is uncomfortable: most of the binding methods lack ergonomic design, and comfort is difficult to guarantee ;The design structure is not integrated: the battery and the motor are scattered and tied in different parts, which is easy to cause troubles for underwater activities; the design is not streamlined: the propeller does not consider fluid mechanics, the direction of the water flow inlet and outlet or the injection efficiency is unreasonable, and it is not beautiful enough; the structure It is not convenient for processing and manufacturing: some use magnetic coupling or crankshaft linkage mechanism to realize power transmission, which increases the design complexity of the mechanical structure, which is unreasonable
