The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0035] Such as Figures 1 to 3As shown in the figure, this embodiment provides a thruster, which includes a waterproof housing 1, a mesh housing 2, a mesh component 3, and a blade component 4. Among them, the mesh housing 2 can enclose a receiving cavity 15 with the waterproof housing 1, at least part of the blade component 4 is located in the receiving cavity 15, the blade component 4 is installed on the waterproof housing 1, and can drive the unmanned boat housing 8 to move; the mesh housing 2 has a drain hole 21 and a water inlet hole 24 that communicate with each other, and is detachably connected to the waterproof housing 1. In this way, when the blade component 4 fails and needs to be repaired, the mesh housing 2 can be directly removed to repair the blade component 4; at the same time, the mesh component 3 is detachably arranged on the mesh housing 2 and covers the water inlet hole 24. The mesh component 3 can block foreign objects from entering the water inlet hole 24, and if the mesh component 3 is severely blocked, it can be directly removed for cleaning or replacement. Compared with the pod-mounted and bottom-mounted methods of thrusters in the prior art, the thruster provided by the present invention effectively solves the problem of difficult disassembly and assembly of the thruster when the thruster needs to be repaired or foreign objects enter in the prior art.

[0036] In this embodiment, the mesh component 3 includes a first water inlet mesh 31 and a second water inlet mesh 32. Among them, the first water inlet mesh 31 can be detachably arranged on the mesh housing 2 and cover the water inlet hole 24. In this way, when the first water inlet mesh 31 is severely blocked, the first water inlet mesh 31 can be directly removed for cleaning or replacement; in order to further prevent foreign objects from entering the water inlet hole 24, the second water inlet mesh 32 is detachably arranged on the first water inlet mesh 31, so as to further block foreign objects from entering the water inlet hole 24.

[0037] Further, as Figure 1 and Figure 2 shown, the mesh holes of the first water inlet mesh 31 are larger than those of the second water inlet mesh 32. In this way, when working in a water area with a lot of waterweeds, foreign objects such as waterweeds can be effectively prevented from entering the water inlet hole 24 and winding around the blade component 4, thereby damaging the thruster.

[0038] Optionally, the first water inlet mesh 31 is connected to the mesh housing 2 through fasteners such as bolts; similarly, the second water inlet mesh 32 is connected to the first water inlet mesh 31 through fasteners such as bolts.

[0040] Optionally, both the first fastener 51 and the second fastener 52 are bolts.

[0041] In some embodiments, the blade assembly 4 includes a blade mounting member 41 and a blade driving portion 42. One end of the blade mounting member 41 passes through the waterproof housing 1 and is sealingly connected to the waterproof housing 1. This arrangement can effectively prevent water from entering the hull of the unmanned boat through the gap between the blade mounting member 41 and the waterproof housing 1. Among them, the blade driving portion 42 is detachably connected to the other end of the blade mounting member 41 and the inner wall of the waterproof housing 1, so that when the blade driving portion 42 fails, it can be quickly disassembled; the blade driving portion 42 is provided to drive the hull 8 of the unmanned boat to move.

[0042] Among them, the thruster includes a seal 6, and the waterproof housing 1 has a mounting hole 13. One end of the blade mounting member 41 passes through the mounting hole 13, and the seal 6 is sleeved on the outer wall of the blade mounting member 41. The seal 6 is provided to seal the gap between the outer wall of the blade mounting member 41 and the inner wall of the mounting hole 13, thereby preventing water from entering the hull 8 of the unmanned boat.

[0043] Optionally, there are multiple seals 6, and the multiple seals 6 are sleeved on the outer wall of the blade mounting member 41 at intervals.

[0044] In this solution, the blade mounting member 41 is a mounting sleeve, including a cylindrical tube and a conical tube connected to each other. One end of the cylindrical tube passes through the waterproof housing 1 and is sealingly connected to the waterproof housing 1. The conical tube and the blade driving portion 42 are connected by fasteners such as bolts.

[0045] Specifically, the blade driving portion 42 includes a quick-release seat 421, a driving motor 422, and a propeller 423. Among them, the seat body of the driving motor 422 and the other end of the blade mounting member 41 are connected by fasteners such as bolts.

In this way, the driving motor 422 can drive the propeller 423 to rotate, thereby generating forward power. Among them, the quick-release seat 421 is connected to the seat body of the driving motor 422 by bolts, and the propeller 423 is sleeved on the output shaft of the driving motor 422 and is threadedly connected to the output shaft of the driving motor 422 by a nut.

[0046] In some embodiments, the inner wall of the waterproof housing 1 has a quick-release groove 14. The quick-release seat 421 can be embedded in the quick-release groove 14 and is snap-fitted with the quick-release groove 14, so that the quick-release seat 421 can be installed on the waterproof housing 1 and can be quickly disassembled and assembled.

[0047] Specifically, the thruster includes a waterproof rubber plug 7, and the blade mounting member 41 has a through hole 411 communicating with the accommodation cavity 15. The waterproof rubber plug 7 is inserted into the through hole 411 and is sealingly connected to the inner wall of the through hole 411, so as to prevent water from entering the unmanned boat housing 8 through the through hole 411. Among them, the waterproof rubber plug 7 is located at one end of the blade mounting member 41 away from the blade driving part 42, and the waterproof rubber plug 7 has a plurality of wire passing holes 71. The provision of the wire passing holes 71 enables the cable of the driving motor 422 to pass through.

[0048] As Figure 4 and Figure 5 shown, this embodiment also provides an unmanned boat, which includes an unmanned boat housing 8 and a plurality of thrusters 9 in the above-mentioned solutions. The plurality of thrusters 9 are arranged at intervals on the unmanned boat housing 8. By using the unmanned boat in this embodiment, when the blade assembly 4 fails and needs to be repaired, the mesh housing 2 can be directly removed, so as to repair the blade assembly 4. At the same time, the mesh assembly 3 is detachably arranged on the mesh housing 2 and covers the water inlet hole 24. The mesh assembly 3 can block foreign objects from entering the water inlet hole 24, and if the mesh assembly 3 is severely blocked, it can be directly removed for cleaning or replacement. Compared with the prior art in which the thruster is installed in a pod type and at the bottom of the boat, the thruster provided by the present utility model effectively solves the problem that it is difficult to disassemble and assemble the thruster when the thruster needs to be repaired or foreign objects enter in the prior art.
