[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4 In the utility model, a waterproof mechanism for a marine motor includes a base plate 1, a sliding groove 2 is opened on the base plate 1, a semi-enclosed arc-shaped waterproof cover 3 is fixedly connected to the top of the base plate 1, a mounting plate 4 is slidably connected to the inside of the sliding groove 2 and the rear end is fastened by bolts, the top of the mounting plate 4 is fixedly connected to the motor body 5 by bolts, the top of the mounting plate 4 is fixedly connected to the closing plate 6, the closing plate 6 is clamped with the port of the semi-enclosed arc-shaped waterproof cover 3, the outer side of the semi-enclosed arc-shaped waterproof cover 3 and the closing plate 6 are provided with a waterproof sealing ring 7, and the port of the semi-enclosed arc-shaped waterproof cover 3 is provided with a sealing ring 7. It is equipped with a reinforced waterproof mechanism 8, which is snap-fitted with the outer side of the closing plate 6. Two limit mechanisms 9 for positioning the mounting plate 4 are installed on the base plate 1. The closing plate 6 is rotated and connected to a connecting shaft 10. The output end of the motor body 5 is horizontally docked with the connecting shaft 10 through a coupling. A cooling fan 11 is fixedly installed inside the semi-enclosed arc-shaped waterproof cover 3, and a cooling curved pipe 12 is installed on the outside of the semi-enclosed arc-shaped waterproof cover 3. Both ends of the cooling curved pipe 12 are plugged into the interior of the semi-enclosed arc-shaped waterproof cover 3, and one end of the cooling curved pipe 12 is connected and fixed to the cooling fan 11.

[0022] In the present invention, the base plate 1 is used as the installation support. During installation, the limiting mechanism 9 is first released and the mounting plate 4 is then slid out along the inside of the sliding groove 2. The output end of the motor body 5 is then placed toward the connecting shaft 10. The motor body 5 is then linearly pushed to move so that its output end is horizontally docked with the connecting shaft 10. The motor body 5 and the mounting plate 4 are then locked and fixed with bolts to complete the motor installation. The mounting plate 4 is then reset along the sliding groove 2 and bolted from the rear to complete the installation, so that the closing plate 6 and the port of the semi-enclosed arc waterproof cover 3 are clamped and sealed to form a closed space. At the same time, the two limiting mechanisms 9 are used to position the mounting plate 4 so that the closing plate 6 and the port of the semi-enclosed arc waterproof cover 3 are tightly clamped. The interior of the reinforced waterproof mechanism 8 is then inflated to achieve the sealing of the closing plate 6 and the semi-enclosed arc. The sealing and waterproofing effect between the waterproof covers 3 is better, and the wear and tear on the waterproof structure during disassembly is reduced. When in use, the cooling fan 11 is started to drive the air inside the closed space to flow into the cooling curved pipe 12, and the external water flow continuously impacts the cooling curved pipe 12, so as to achieve continuous cooling of the internal air to achieve heat dissipation of the motor body 5, while ensuring waterproof sealing, thereby realizing the device with a flexible waterproof structure design, reducing the wear and tear on the waterproof sealing structure during loading and unloading, and improving the loading and unloading efficiency. It solves the problem in the prior art that when the motor is disassembled and maintained, the waterproof structure needs to be continuously disassembled and assembled, which easily causes fatigue of the connection structure and the sealing structure, resulting in reduced performance and life of the waterproof structure, and the need to completely dismantle the waterproof structure during motor maintenance, resulting in low operating efficiency.

[0023] See also Figure 1 and Figure 3 , wherein: the reinforced waterproof mechanism 8 includes an inflation nozzle 81 and an airbag ring 82, the bottom of the inflation nozzle 81 is inserted into the interior of the semi-closed arc-shaped waterproof cover 3, the bottom end of the inflation nozzle 81 is connected and fixed to the airbag ring 82, the upper half of the cross-section of the airbag ring 82 is fixedly connected to the inner wall of the semi-closed arc-shaped waterproof cover 3, and the lower half of the cross-section of the airbag ring 82 is in close contact with the outer side of the closing plate 6.

[0024] In the present invention, an external air source is connected through the inflation nozzle 81, and nitrogen is injected into the airbag ring 82, so that the airbag ring 82 maintains high pressure, and strengthens the seal with the outer edge of the closing plate 6, making it more waterproof. At the same time, when disassembling, the internal gas can be extracted first to make the airbag ring 82 retract, so that the protection of the airbag ring 82 is reduced during disassembly.

[0025] See also Figure 3 , wherein: a semi-arc groove 61 is opened on the outer side of the closing plate 6 to fit with the airbag ring 82.

[0026] In the present invention, the semi-arc groove 61 allows the airbag ring 82 and the closing plate 6 to fit more tightly together.

[0027] See also Figure 3 , wherein: a sealing ring group 62 is provided on one side of the closing plate 6 facing the semi-closed arc-shaped waterproof cover 3.

[0028] In the present invention, the sealing ring assembly 62 is used to improve the sealing effect between the closing plate 6 and one side of the semi-closed arc-shaped waterproof cover 3, thereby improving the waterproof performance.

[0029] See also Figure 1 and Figure 2 , wherein: a waterproof rubber strip 21 is fixedly connected to the inner side of the sliding groove 2 around the periphery, and the inner side of the waterproof rubber strip 21 contacts and seals with the inner side of the mounting plate 4.

[0030] In the present invention, the waterproof strip 21 is used to provide a better sealing and waterproof effect between the mounting plate 4 and the sliding groove 2 .
