[0002] At present, with the improvement of living standards, diving is becoming more and more popular among people. Underwater thrusters are increasingly respected by diving enthusiasts because they can provide a faster, more labor-saving, safer and more environmentally friendly underwater diving experience. Underwater thrusters can provide sufficient power in deep water and are suitable for a variety of underwater activities such as snorkeling, free diving, and scuba diving.

[0030] Embodiment 1:

[0031] like Figure 1-6 As shown, a diving underwater propulsion device includes a shell 1 and a plurality of electric propellers 2 arranged outside the shell 1.

[0032] A brushless electric speed controller 3, a circuit board 4, a battery management board 5 and a large-capacity battery pack 6 are installed inside the shell 1. The brushless electric speed controller 3 is controlled and coordinated with the electric propeller 2 through an integrated wiring harness. The circuit board 4 is respectively connected to the brushless electric speed controller 3 and the battery management board 5 through an integrated wiring harness. The battery management board 5 is connected to the large-capacity battery pack 6 through an integrated wiring harness, and the circuit board 4 is connected to a waterproof switch assembly 7 through an integrated wiring harness. The waterproof switch assembly 7 is fixedly installed on the outer wall of the shell 1. A charging port 9 for charging the large-capacity battery pack 6 is fixed on the inner wall of one side of the shell 1, and a waterproof bolt cap 8 is threadedly connected to the outer wall of the charging port 9.

[0033] The brushless electric regulator 3 is used to protect and control the electric propeller 2; the battery management board 5 is used to protect the large-capacity battery pack 6 to prevent the battery from overcharging, over-discharging, over-current and short circuit, thereby extending the service life of the battery and ensuring safe use.

[0034] When the device is in use, it can be installed and fixed with the diving device by means of bolts, clamps, etc., and can be adjusted or improved accordingly according to actual production needs. The device is started by using the waterproof switch component 7. After the circuit board 4 receives the start signal, it controls the brushless electric regulator 3 to start multiple electric propellers 2, and the electric propellers 2 are used to provide power for the diving equipment. After use, the waterproof switch component 7 is used to close the device. When the large-capacity battery pack 6 needs to be charged, the charging port 9 is rotated and removed, and the charger compatible with the waterproof bolt cap 8 is plugged into the waterproof bolt cap 8 to charge the large-capacity battery pack 6.

[0035] By setting up multiple sets of electric propellers 2, the device can provide greater propulsion force for the device, which can reach the target diving point faster, reduce the movement time in the water, and thus increase the underwater stay time and exploration range. It can also overcome water pressure and resistance in deep water areas to ensure a smooth diving process.

[0036] Embodiment 2:

[0037] A diving underwater propeller, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 4 , 5 As shown:

[0038] The electric propeller 2 includes a hollow cylinder 11 and a fixed cylinder 12. The hollow cylinder 11 is fixedly mounted on the outer wall of the housing 1 through a bracket 10, and the fixed cylinder 12 is fixedly mounted on the inner wall of the hollow cylinder 11 through a connecting rod.

[0039] Hollow plates 13 are fixed to the outer walls of both sides of the fixed cylinder 12, and guide blocks 14 are fixedly connected to the outer walls of the hollow plates 13. The guide blocks 14 can reduce the resistance of water flow on the propeller surface, thereby improving the propulsion efficiency.

[0040] The inner wall of the fixed cylinder 12 is fixed with a brushless motor 15 by bolts, the brushless motor 15 is connected to the brushless electric regulator 3 through an integrated wiring harness, and the output shaft of the brushless motor 15 is fixedly connected to the rotating shaft 16 through a coupling, and the outer wall of the rotating shaft 16 is keyed to a bevel gear 3 23.

[0041] The outer wall of the rotating shaft 16 is rotatably connected with a hollow shaft 21, the outer wall of the hollow shaft 21 is key-connected with a bevel gear 22, and the outer walls of the rotating shaft 16 and the hollow shaft 21 are fixedly connected with a blade 2 20 and a blade 1 19 respectively.

[0042] The inner wall of the fixed cylinder 12 is fixedly connected with a mounting frame 18 , and the inner wall of the mounting frame 18 is rotatably connected with a bevel gear 17 that meshes with a bevel gear 22 and a bevel gear 3 23 .

[0043] Start the brushless motor 15 to drive the rotating shaft 16 to drive the bevel gear three 23 and the blade two 20 to rotate. Under the transmission cooperation of the bevel gear one 17, the bevel gear two 22 drives the hollow shaft 21 and the blade one 19 to rotate, so that the blade one 19 and the blade two 20 can rotate synchronously but in different directions.

[0044] By providing the counter-rotating blades 19 and 20, the device can more effectively utilize the power of the water flow and reduce energy loss, thereby improving the propulsion efficiency, reducing energy consumption, and further improving the endurance of the device.

[0045] Working principle: When the device is in use, firstly, the device is installed on the diving equipment by means of bolts, clamps, etc., and then the device is started by using the waterproof switch assembly 7 to drive the diving equipment to dive into deep waters. During this process, the brushless motor 15 drives the rotating shaft 16 to drive the bevel gear three 23 and the blade two 20 to rotate. With the cooperation of the bevel gear one 17 and the bevel gear two 22, the bevel gear two 22 can drive the hollow shaft 21 and the blade one 19 to rotate in the opposite direction, thereby improving the propulsion efficiency, reducing energy consumption, and improving the endurance of the device.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
