[0002] Portable propulsion devices are used to power various equipment or carriers. They are characterized by their small size, light weight, and ease of carrying and operation. They are typically battery-powered and equipped with small motors and propellers, providing powerful yet quiet operation. Some also feature waterproof and pressure-resistant properties, allowing them to work underwater at varying depths.

[0003] Portable thrusters are primarily used in diving, helping divers move more easily in the water, saving energy, and increasing the enjoyment and exploration range of diving. They can also be used for underwater photography and scientific research, carrying cameras, lighting equipment, etc., to facilitate the shooting and study of the underwater environment. Furthermore, they can serve as a power unit for underwater drones and other detection equipment for underwater exploration missions.

[0004] Existing portable propulsion devices still have some problems. They have shortcomings in water applications, such as poor stability during operation, resulting in a poor underwater swimming experience for users; and poor filter stability, which makes them prone to deformation and affects their service life. Therefore, it is necessary to solve these problems. Utility Model Content

[0034] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0035] like Figures 1 to 4As shown, a portable underwater propulsion device includes:

[0036] Thruster body 1;

[0037] A flow deflector 2 is placed on one side of the thruster body 1;

[0038] The first guide element 3 is placed between the propeller body 1 and the guide shield 2, and its two ends are fixedly connected to the propeller body 1 and the guide shield 2 respectively.

[0039] The second guide element 4 is placed between the propeller body 1 and the guide shield 2, and its two ends are fixedly connected to the propeller body 1 and the guide shield 2 respectively; the first guide element 3 is located on one side of the second guide element 4.

[0040] Handle 5, one end of which is fixedly connected to the first guide member 3 and the other end of which is fixedly connected to the second guide member 4;

[0041] The propeller 6 is rotatably placed inside the flow guide 2. The propeller 6 is connected to the output end of the thruster body 1, and the thruster body 1 drives the propeller 6 to rotate.

[0042] In a specific application of this embodiment, the battery inside the thruster body 1 supplies power to the motor inside the thruster body 1. The output end of the motor drives the propeller 6 to rotate. During the rotation of the propeller 6, the water inside the guide shroud 2 is pushed, so that the portable underwater thruster moves.

[0043] In this embodiment, the propeller body 1 and the flow guide 2 are fixed by the first flow guide 3 and the second flow guide 4, which can improve the stability of the flow guide 2. The first flow guide 3 and the second flow guide 4 can also maintain the predetermined moving posture of the propeller body 1, reduce the disturbance of the undercurrent, make the movement of the propeller body 1 more stable, improve the movement accuracy, enhance the anti-interference ability, and improve the user's underwater swimming experience. The handle 5 makes it convenient for the user to hold the handle 5 and operate the portable underwater propeller.

[0044] In the above embodiment, there are two first guide members 3 and two second guide members 4. The two first guide members 3 and the two second guide members 4 are arranged sequentially at intervals along the surface of the propeller body 1. Each first guide member 3 is fixedly connected to a second guide member 4 through a handle 5.

[0045] In a specific application of this embodiment, two first guide members 3 and two second guide members 4 are arranged sequentially and at intervals along the surface of the propeller body 1. When the propeller body 1 moves in the water, the two first guide members 3 and two second guide members 4 interact with the water flow, changing the water flow distribution around the propeller body 1, reducing external interference, and maintaining the stability of movement.

[0046] In the above embodiments, both the first guide member 3 and the second guide member 4 are arc-shaped plate structures; the length of the first guide member 3 is greater than the length of the second guide member 4.

[0047] In the above embodiments, a filter screen 7 is fixedly provided between two adjacent first guide members 3, between adjacent first guide members 3 and second guide members 4, and between two adjacent second guide members 4, and the plurality of filter screens 7 are arranged in an arc-shaped structure.

[0048] In a specific application of this embodiment, the filter screen connecting the propeller body 1 and the flow guide 2 is divided into multiple small filter screens 7. Each filter screen 7 is fixedly connected to the first flow guide 3 and the second flow guide 4 that are close to it, which can improve the stability of the filter screen 7. The multiple filter screens 7 are all arc-shaped, which can further improve the stability of the filter screen 7.

[0049] The above embodiments also include:

[0050] A flow guide net 8 is fixedly placed inside the flow guide cover 2, and the flow guide net 8 is located on the end of the propeller 6 away from the propeller body 1.

[0051] In this specific application, the flow guide net 8, together with the flow guide cover 2 and the filter screen 7, wraps around the propeller 6. This protects the propeller 6 during rotation, preventing debris in the water from being drawn into the flow guide cover 2 and causing damage to the propeller 6. It also prevents divers from getting their limbs stuck into the flow guide cover 2 and causing injury, thus improving safety.

[0052] In the above embodiments, the pore size of the filter holes on the flow guide net 8 gradually increases from the center to the edge.

[0053] In the specific application of this embodiment, during the rotation of the propeller 6, the water flow velocity at the edge of the propeller 6 is greater than that at its center. The aperture of the guide net 8 gradually increases from the center to the edge, so that water can be quickly discharged through the guide net 8 after the propeller 6 rotates, reducing the interference of the guide net 8 on the water flow velocity and enabling the propeller 6 to maintain efficient operation.

[0054] The above embodiments also include:

[0055] The heat dissipation pipe 9 has one end located at the end of the thruster body 1 away from the propeller 6, and the other end passes through the thruster body 1 to the middle of the thruster.

[0056] In this specific application, the heat dissipation pipe 9 is made of heat dissipation material. One end of the heat dissipation pipe 9 is located at the end of the thruster body 1, and the other end extends into the thruster body 1 and extends to the middle end face of the thruster. The heat dissipation pipe 9 is located inside the thruster body 1 and is in close contact with the motor inside the thruster body 1. The heat generated during the operation of the motor is conducted to the outside of the thruster body 1 through the heat dissipation pipe 9, thereby achieving heat dissipation of the motor inside the thruster body 1. During the operation of the thruster body 1, water is introduced into the heat dissipation pipe 9 from one end and discharged through the other end. The water flow is used to dissipate heat from the heat dissipation pipe 9 and the motor, further improving the heat dissipation efficiency. By dissipating heat from the motor, the output power of the motor can be increased, thereby improving the operating efficiency of the thruster body 1.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
