Description

Technical Field

[0001] This utility model relates to the field of propulsion technology, and in particular to a one-key return water rescue propulsion device. Background Technology

[0002] With the rapid advancement of urbanization across China, cities of varying sizes have gradually become the main areas for people's work, residence, and entertainment. Current urban design often incorporates water environment planning, resulting in various forms of water bodies appearing throughout cities. These bodies protect and regulate the local urban environment while providing recreational and even working opportunities. These water bodies vary in form, some natural and some artificial, offering convenience but also concealing safety hazards. Recent accident statistics show that drowning accidents are frequent and increasing year by year. Even those specializing in diving face risks of drowning and poisoning during their work. With increasing emphasis on the right to life, the pursuit of personal safety is becoming more prominent and highly valued. It can be predicted that the use of advanced technological equipment to assist in water rescue will inevitably become a new trend in the development of water rescue equipment.

[0003] Most traditional propulsion equipment currently has the limitation of a single floating state, supporting only a single operation mode on the water surface or underwater.

[0004] Furthermore, some buoyancy-adjustable devices suffer from significant delays, making them unsuitable for scenarios requiring rapid switching, such as shipwrecks and undercurrents. Additionally, devices with a single propeller layout are prone to torque imbalance in turbulent waters, increasing the likelihood of yaw. To address these issues, a rescue propulsion system is urgently needed. Utility Model Content

[0005] The purpose of this invention is to provide a one-click return water rescue propulsion device that can operate both on the water surface and underwater.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A one-key return water rescue thruster includes two thrusters, with a first support frame fixedly mounted between the two thrusters. A second support frame is fixedly mounted on the first support frame. A first handle and a second handle are fixedly mounted on both sides of the second support frame. The two handles are symmetrically arranged along the two thrusters. The first handle has a first start / stop button for controlling the start and stop of one thruster, and the second handle has a second start / stop button for controlling the start and stop of the other thruster. The first handle also has a one-key return setting button, and the second handle has a one-key return start / stop button. A main control box is mounted on the second support frame.

[0008] As a further feature of this invention, the main control box is provided with a forward / reverse switch for controlling the forward and reverse rotation of the rotating blades in the first and second thrusters, and a high / low speed switch for controlling the rotational speed of the rotating blades in the first and second thrusters.

[0009] As a further feature of this invention, the main control box is also equipped with a charging port, a power display screen, and a main power switch.

[0010] As a further feature of this invention, the main control box is also equipped with indicator lights.

[0011] As a further feature of this invention, the main control box is equipped with a nine-axis attitude sensor, a depth sensor, and a temperature and humidity sensor.

[0012] As a further feature of this invention, the main control box is equipped with a GPS module.

[0013] As a further feature of this invention, the thruster includes a first housing with a power source inside and a second housing with helical blades inside, and a plurality of latches are provided between the first housing and the second housing.

[0014] As a further feature of this invention, a crossbeam is fixedly provided between the two thrusters, and the crossbeam is arranged in a direction perpendicular to the axis of the thrusters.

[0015] The beneficial effects of this utility model are:

[0016] 1. The principle of this utility model for dual surface and underwater support operation is to achieve a micro-buoyancy effect by adjusting the weight of the entire machine, and then use the thrust of the propeller to achieve a transition between the surface and underwater operating environments. In surface operation mode, the propeller is adjusted to a downward-facing position using the handle, with one end of the propeller blades tilted upwards. The propeller is then activated using the button on the handle, allowing the user to move from the surface to the underwater area. Conversely, in underwater operation mode, the propeller is adjusted to an upward-facing position, with one end of the propeller blades tilted upwards, allowing the user to rise to the surface. This micro-buoyancy adjustment structure significantly reduces the buoyancy or gravity that the equipment needs to overcome during water operations, positively impacting the equipment's range and weight reduction.

[0017] 2. This utility model enables steering by setting start / stop buttons on the two thrusters. When steering is required, one thruster is turned off, and the other thruster can be used to achieve steering, which is very convenient.

[0018] 3. The structure of the dual thrusters is more stable and less prone to torque imbalance during operation. Attached Figure Description

[0024] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] One-click return water rescue thruster, for reference Figures 1 to 3 It includes two thrusters 1, a support frame is provided between the two thrusters 1, and a first handle 4 and a second handle 5 are connected through the support frame. The two handles are symmetrically arranged along the two thrusters 1.

[0026] In practical operation, the operator controls the forward movement of the entire propeller 1 using the first handle 4 and the second handle 5. A slight positive buoyancy is achieved by adjusting the counterweight, and the thrust of the propeller 1 facilitates the transition between surface and underwater working environments. When operating on the surface, the propeller 1 is adjusted to a downward-facing position using the handle, with one end of the propeller blades tilted upwards, before starting the propeller 1. This operation allows the operator to move from the surface to the underwater area. Conversely, when operating underwater, the propeller 1 is adjusted to an upward-facing position, with one end of the propeller blades tilted downwards, before starting the propeller 1 to surface.

[0027] To better control the thrusters 1, a first start / stop button 6 is provided on the first handle 4 to control the start and stop of one thruster 1, and a second start / stop button 7 is provided on the second handle 5 to control the start and stop of the other thruster 1. A one-key return setting button 8 is also provided on the first handle 4, and a one-key return start / stop button 9 is provided on the second handle 5. In actual operation, the start and stop of the two thrusters 1 are controlled by the first start / stop button 6 and the second start / stop button 7 respectively. This provides convenient control and allows for control of the overall steering of the thruster 1. Specifically, when steering is required, one thruster 1 is deactivated, and the entire thruster 1 will veer to one side under the action of the other thruster 1, achieving steering. To veer in the other direction, simply adjust the start / stop status of the different thrusters 1, making steering more convenient.

[0028] In addition, this embodiment is equipped with a one-key return setting button 8 and a one-key return start / stop button 9, which are matched with an algorithm program and corresponding sensors. The return point of the one-key return can be set by using the one-key return setting button 8. During operation, if it is necessary to return to a designated location, the one-key return function can be activated by using the one-key start / stop button, and the thruster 1 can return, which is very convenient.

[0029] A main control box 10 is also installed on the support frame, integrating various sensors, modules, and control buttons. Specifically, the main control box 10 has a forward / reverse switch 11 that controls the forward and reverse rotation of the rotating blades in the first and second thrusters 1, and a high / low speed switch 12 that controls the speed of the rotating blades in the first and second thrusters 1. By setting the forward / reverse switch 11, the forward and reverse rotation of the helical blades of the two thrusters 1 can be realized, thereby controlling the forward and backward movement of the thrusters 1. By setting the high / low speed switch, the speed of the thrusters 1 can be controlled at several levels from low to high speed, which is convenient for operators to adjust.

[0030] Secondly, the main control box 10 is equipped with a nine-axis attitude sensor, a depth sensor, a temperature and humidity sensor, and a GPS module. Through the function of these sensors, the internal condition of the device can be monitored in real time, as well as the perception of the external environment and itself. By combining the fusion of multiple sensors, GPS positioning, and control algorithms, the intelligent return-to-home operation can be achieved.

[0031] In this embodiment, the thruster 1 includes a battery, a first housing 16 with the battery inside, a helical blade, and a second housing 17 with the helical blade inside. The battery provides power for the entire device and the rotation of the helical blade, and the rotation of the helical blade provides the power for the device to travel. Multiple latches 18 are provided between the first housing 16 and the second housing 17. The multiple latches 18 can fix the two housings together and also facilitate the disassembly of the two housings for easy maintenance.

[0032] In order to charge the battery, a charging port 13 is provided on the main control box 10, and a power display screen 14 is also provided to show the remaining power of the thruster 1, so that the operator can easily observe the remaining power of the thruster 1. The main control box 10 is also provided with a main power switch 15. When the thruster 1 is not working, the main power switch 15 is turned off to avoid wasting power.

[0033] To better understand the current working status of thruster 1, indicator lights are also installed on the main control box 10. The current indicator color can indicate whether thruster 1 is in normal condition and what working state it is currently in.

[0034] For the support frame, in order to facilitate manufacturing and installation, the support frame is divided into a first support frame 2 and a second support frame 3. The cross-sectional shape of the first support frame 2 is an inverted "U"-shaped structure. The lower part of the opening of the first support frame 2 is fixedly connected to the two pushers 1, which facilitates the fixed connection of the two pushers 1. The second support frame 3 is set on the top of the first support frame 2. The cross-sectional shape of the second support frame 3 is a "U"-shaped structure, which facilitates connection with the first support frame 2 and also facilitates the installation of the first handle 4 and the second handle 5. In addition, the main control box 10 is also installed on the second support frame 3.

[0035] To further stabilize the two thrusters 1, a crossbeam 19 is installed below the first support frame 2 between the two thrusters 1. The crossbeam 19 is installed perpendicular to the axis of the thrusters 1. In addition to further stabilizing the two thrusters 1, the crossbeam 19 also serves to connect the operator. Specifically, during use, a safety belt can be used with a buckle to connect the operator to the crossbeam 19. This allows the operator to free their hands to perform other operations while performing tasks. In case of danger, the operator can quickly detach from the equipment using the buckle.

[0036] It should be noted that the specific wiring connections between the battery, spiral blades, and various sensors and modules in this embodiment are conventional techniques used by those skilled in the art, aimed at achieving the technical effects of this embodiment. Each switch is the final functional execution structure, and the wiring and other corresponding accessories used to implement its function are also conventional settings in the art, and will not be described in detail here.

[0037] In another embodiment, the two thrusters 1 can be replaced with a structure of two or more thrusters 1. The specific installation structure can be adapted to achieve the technical effect of operating both on the water surface and underwater through the multi-thruster 1 structure.

[0038] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
