[0024] The motor 13 drives the turbine blades 14 to rotate, thereby driving the vehicle to move in the water. During operation, the waterproof structure 2 protects the battery 32 to prevent water from entering the storage cavity for storing the battery on the top of the electric fin housing 1.

[0025] like Figure 2 As shown, a sealing groove 16 is opened on the right part of the electric fish fin housing 1, a fixing plate 17 is fixedly connected to the top of the inner cavity of the electric fish fin housing 1, and a heat sink 18 is fixedly connected to the bottom end of the fixing plate 17.

[0026] The heat emitted by the battery 32 is absorbed by the heat conducting plate, which transfers the heat to the fixing plate 17, and then the fixing plate 17 transfers the heat to the heat sink 18. Since the heat sink 18 is located directly above the motor 13, and the motor 13 is located in the water, the heat accumulated on the heat sink 18 can be taken away, thereby achieving a heat dissipation effect.

[0027] like Figure 2 , Figure 3 As shown, the waterproof structure 2 includes a shell cover 21, the bottom of the shell cover 21 is fixedly connected to the top of the electric fish fin housing 1 by bolts, the top of the shell cover 21 is fixedly connected to a mounting plate 22, the bottom end of the shell cover 21 is fixedly connected to a sealing ring 23, the outer wall of the sealing ring 23 is plugged into the top of the electric fish fin housing 1, the right part of the shell cover 21 is fixedly connected to a fixing block 24 by bolts, the inner wall of the fixing block 24 is plugged with a sealing strip 25, the outer wall of the sealing strip 25 is overlapped with the right part of the shell cover 21, and the diameter of the sealing strip 25 is larger than the width of the entrance of the sealing groove 16.

[0028] By unscrewing the bolts fixing the shell cover 21 and the electric fish fin shell 1, the shell cover 21 can be removed, so that the outer wall of the sealing ring 23 is no longer plugged into the inner wall of the electric fish fin shell 1, and then the battery 32 can be replaced. Later, when it is necessary to check whether there is water in the cavity for storing the battery 32 at the top of the inner cavity of the electric fish fin shell 1, the bolts used to fix the fixing block 24 and the shell cover 21 can be unscrewed, and then the fixing block 24 can be removed, and then the sealing strip 25 is pulled to make the outer wall of the sealing strip 25 disengage from the inner wall of the sealing groove 16. At the same time, the sealing strip 25 drives the sealing block 26 to move synchronously, so that the outer wall of the sealing block 26 is no longer engaged with the inner wall of the sealing groove 16, and the outer wall of the limit strip 27 is not plugged into the inner wall of the electric fish fin shell 1, so that the sealing block 26 can be taken out, and it is detected whether there is water in the cavity for storing the battery 32 at the top of the electric fish fin shell 1 to avoid water leakage of the sealing block 26.

[0029] like Figure 2-Figure 4 As shown, a sealing block 26 is fixedly connected to the bottom end of the sealing strip 25 , and a limiting strip 27 is fixedly connected to the outer wall of the sealing block 26 . The outer wall of the limiting strip 27 is snap-fitted to the inner wall of the electric fin housing 1 .

[0030] The outer wall of the sealing block 26 and the sealing strip 25 are plugged into the inner wall of the sealing groove 16. Since the outer diameter of the sealing strip 25 is larger than the width of the entrance of the sealing groove 16, when the outer wall of the sealing strip 25 is completely plugged into the inner wall of the sealing groove 16, the sealing strip 25 will not separate from the inner wall of the sealing groove 16 without the action of external force, and the sealing block 26 drives the limiting strip 27 to be plugged into the inner wall of the electric fin housing 1, and the limiting strip 27 limits the sealing block 26 to prevent the sealing block 26 from falling off the inner wall of the sealing groove 16, thereby achieving a sealing and waterproof effect.

[0031] like Figure 2 , Figure 5 As shown, the battery mechanism 3 includes a placement rack 31 , the bottom end of the placement rack 31 is fixedly connected to the top end of the heat conducting plate, and the inner wall of the placement rack 31 is plugged with a battery 32 .

[0032] The batteries 32 are differentiated by placing the rack 31 to avoid close contact between the batteries 32, which would cause overheating of the batteries 32 and affect their service life. At the same time, multiple batteries 32 provide sufficient power for the motor 13 to ensure that the motor 13 can reach maximum power operation.

[0033] The working principle of the utility model is as follows: when in use, the device is taken out, and the battery 32 is installed in the placement frame 31, and then the shell cover 21 and the electric fish fin shell 1 are fixedly connected by bolts, and then the mounting plate 22 and the running vehicle are connected by existing technology, so that the electric fish fin can be quickly connected to the running vehicle, and because the battery 32 is a plurality of independent individuals, it is more convenient to arrange the position of the battery 32, which reduces the space occupied by the battery 32, thereby reducing the overall volume of the device, making the device more convenient to carry, and then the motor 13 can be started to drive the turbine blades 14 to rotate, thereby driving the vehicle to move in the water. During operation, the electric The heat emitted by the pool 32 is absorbed by the heat conducting plate, and the heat conducting plate transfers the heat to the fixing plate 17, and then the fixing plate 17 transfers the heat to the heat sink 18. Because the heat sink 18 is located directly above the motor 13, and the motor 13 is located in the water, the heat accumulated on the heat sink 18 can be taken away, thereby achieving a heat dissipation effect. Subsequently, the bolts fixing the shell cover 21 and the electric fish fin shell 1 can be unscrewed, and then the shell cover 21 can be removed, so that the outer wall of the sealing ring 23 is no longer plugged into the inner wall of the electric fish fin shell 1, and then the battery 32 can be replaced. After the battery 32 is taken out from the placement rack 31, a new battery 32 can be placed in the placement rack 31. , thereby completing the replacement of the battery 32. Later, when it is necessary to check whether there is water in the cavity for storing the battery 32 at the top of the inner cavity of the electric fish fin housing 1, the bolts used to fix the fixing block 24 and the shell cover 21 can be screwed out, and then the fixing block 24 can be removed, and then the sealing strip 25 is pulled to make the outer wall of the sealing strip 25 detach from the inner wall of the sealing groove 16. At the same time, the sealing strip 25 drives the sealing block 26 to move synchronously, so that the outer wall of the sealing block 26 is no longer engaged with the inner wall of the sealing groove 16, and the outer wall of the limit strip 27 is no longer plugged into the inner wall of the electric fish fin housing 1, so that the sealing block 26 can be taken out to detect whether there is water in the cavity for storing the battery 32 at the top of the electric fish fin housing 1. Enter to avoid water leakage of the sealing block 26. If there is a sign of water ingress in the cavity where the battery 32 is placed, the sealing block 26 can be replaced, and then the sealing block 26 and the sealing strip 25 are plugged into the inner wall of the sealing groove 16. Because the outer diameter of the sealing strip 25 is larger than the width of the entrance of the sealing groove 16, when the outer wall of the sealing strip 25 is completely plugged into the inner wall of the sealing groove 16, in the absence of external force, the sealing strip 25 will not separate from the inner wall of the sealing groove 16, and the sealing block 26 drives the limiting strip 27 to be plugged into the inner wall of the electric fin housing 1, and the limiting strip 27 limits the sealing block 26 to prevent the sealing block 26 from falling off the inner wall of the sealing groove 16, thereby achieving a sealing and waterproof effect.
