[0002] Diving was originally an activity of entering the water surface with or without professional tools for underwater survey, salvage, repair and underwater engineering. With the development of society, diving has gradually developed into a leisure sport with underwater activities as the main content, so as to achieve the purpose of physical exercise and leisure and entertainment. In the process of diving, a large number of diving equipment are usually used, such as diving suits, oxygen cylinders, etc. Among them, diving thrusters are one of the most common diving equipment, which are mainly used to assist divers to move underwater.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned diving thruster has a streamlined protrusion installed on one side of the cylinder through an elastic member, and the streamlined protrusion is used to elastically unload the force. However, during use, it is impossible to detect whether there are obstacles in the direction of movement, so it is easy to cause collision due to the negligence of the diver himself, and the safety performance is poor;

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0038] See also Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a submersible propulsion device, including a shell 1 and an impact assembly 2, and the impact assembly 2 includes a cylinder 201, a battery 202, a streamlined protrusion 204 and an infrared ranging sensor 205. The infrared ranging sensor 205 is used to detect obstacles in the forward direction of the device, and the power supply of the battery 202 is switched on and off by the infrared ranging sensor 205, thereby solving the problem of poor anti-collision performance in the prior art.

[0039] Specifically, the cylinder 201 is fixedly connected to the rear end surface of the shell 1, and the battery 202 is fixedly connected inside the cylinder 201. The side of the cylinder 201 away from the shell 1 is movably connected to a streamlined protrusion 204 through a buffer spring 203, and the groove 204c of the streamlined protrusion 204 is fixedly connected to an infrared ranging sensor 205. The cylinder 201 is set to install structures such as the battery 202, and the battery 202 is electrically connected to electronic components such as the first drive motor 102 in the shell 1 through wires, so that the propeller is powered by the battery 202. The setting of the streamlined protrusion 204 reduces the resistance of the device, and the infrared ranging sensor 205 is set to detect obstacles in the forward direction.

[0040] Furthermore, a filter shell 101 is clamped on the front end surface of the housing 1, and a first drive motor 102 is fixedly connected to the rear end of the housing 1. A propeller 103 is sleeved on the output shaft of the first drive motor 102. The filter shell 101 is arranged to prevent garbage in the water from entering the housing 1. The first drive motor 102 is arranged to drive the propeller 103 to move, and the thrust generated by the rotation of the propeller 103 drives the user to move underwater.

[0041] The front end surface of the housing 1 is provided with positioning holes 104 around it, and the inside of the positioning holes 104 is fitted with positioning posts 101a in a clearance manner. One end of the positioning posts 101a is welded to the rear end surface of the filter housing 101 around it.

The setting of the sealing plate 105 protects the first drive motor 102 and prevents the first drive motor 102 from contacting water.

[0043] A limiting rod 204a is welded on the front end surface of the streamlined protrusion 204, and one end of the limiting rod 204a away from the streamlined protrusion 204 movably penetrates the rear end surface of the cylinder 201 and is welded with a limiting plate 204b, which is located at the inner rear end of the cylinder 201, and the buffer spring 203 is sleeved on the outer side of the limiting rod 204a. The setting of the limiting rod 204a and the limiting plate 204b is used to movably install the streamlined protrusion 204 and the cylinder 201, and to limit the relative movement between the two.

[0044] The groove 204c is formed on the rear end face of the streamlined protrusion 204, and a protective plate 204d is fixedly connected to the opening of the groove 204c. The protective plate 204d is made of a high-pressure resistant transparent material, and the setting of the protective plate 204d protects the infrared ranging sensor 205.

[0045] The operation process of this embodiment is: first hold the shell 1, and start the first drive motor 102, and power the first drive motor 102 through the battery 202, so that the output shaft of the first drive motor 102 drives the propeller 103 to rotate, and then the thrust generated by the propeller 103 drives the user to move underwater. At the same time, during the movement, the infrared ranging sensor 205 is used to detect obstacles in the forward direction, and when the distance between the obstacle and the device is less than the safe distance, the infrared ranging sensor 205 turns off the power supply of the battery 202 to avoid collision.

The setting of the return spring 304a drives the movable plate 304 to move toward the initial position spontaneously, and the setting of the guide tube 302b guides the movement of the rope 308;

[0050] A rubber sleeve 303a is bonded to the outer wall of the grip 303, and a rubber pad 305a is bonded to the outer wall of the clamping plate 305 on one side close to the grip 303. The provision of the rubber sleeve 303a facilitates the user to grip the grip 303, and the provision of the rubber pad 305a prevents the user's palm from being damaged during the gripping process.
