Further, referring to fig. 6, as another embodiment of the unmanned lifeboat provided by the invention, the first water inlet plate 5 is disposed at the first water inlet 12 of the boat body 1, the first water inlet plate 5 seals the first water inlet 12, and the first water inlet plate 5 is provided with the first filtering holes 51 to prevent the sundries from entering and affecting the operation of the first propulsion device 2.
Further, referring to fig. 4, as another embodiment of the unmanned lifeboat provided by the present invention, a plurality of handles 7 are provided on the hull 1, and locking belts are provided on the handles 7. The handle 7 can be grasped by the person falling into water, and the locking belt on the handle 7 can lock the hand of the person falling into water on the pontoon 14, so that the person falling into water can be prevented from falling from the lifeboat when the stormy waves are large.
Further, referring to fig. 6 and 9, as another embodiment of the unmanned lifeboat provided by the present invention, the first accommodating groove 11 has a first inner guiding wall 111, and the first inner guiding wall 111 is opposite to the first water inlet 12; the first guide inner wall 111 includes a first inclined surface 1111 connected to an edge of a side of the first water inlet 12 remote from the first propulsion device 2, and a second inclined surface 1112 connected to a side of the first inclined surface 1111 remote from the first water inlet 12; the vertical distance between the first inclined surface 1111 and the first water inlet 12 becomes gradually larger in a direction approaching the second inclined surface 1112; the vertical distance between the second inclined surface 1112 and the first water inlet 12 becomes gradually larger in a direction away from the first inclined surface 1111. When the unmanned lifeboat advances, the first propulsion device 2 works, water enters the first accommodating groove 11 from the first water inlet 12, in order to realize smoothness of water entering the first water inlet 12, a first diversion inner wall 111 opposite to the first water inlet 12 is arranged, and after entering from the first water inlet 12, water flows firstly contact with the first inclined plane 1111 and then contact with the second inclined plane 1112, that is, the first diversion inner wall 111 formed by the first inclined plane 1111 and the second inclined plane 1112 provides a diversion structure for entering water flows, so that the water flows enter the first accommodating groove 11 and move along the direction of the first propulsion device 2, and enough propulsion water flows are supplied for the first propulsion device 2 in real time. The vertical distance between the second inclined surface 1112 and the first water inlet 12 becomes gradually larger in a direction away from the first inclined surface 1111; so that a sufficient negative pressure can be formed at the first water inlet 12 for the water flow into the first accommodation groove 11, further ensuring that the propulsion device is supplied with a sufficient propulsion water flow in real time.
Further, referring to fig. 9, as another embodiment of the unmanned lifeboat provided by the present invention, the second accommodating groove 18 has a second inner guiding wall 181, and the second inner guiding wall 181 is opposite to the second water inlet 19; the second diversion inner wall 181 comprises a third inclined surface 1811 connected with the edge of the side of the second water inlet 19 away from the second propulsion device 4, and a fourth inclined surface 1812 connected with the side of the third inclined surface 1811 away from the second water inlet 19; the vertical distance between the third inclined surface 1811 and the second water inlet 19 becomes gradually larger in the direction approaching the fourth inclined surface 1812; the vertical distance between the fourth inclined surface 1812 and the second water inlet 19 becomes gradually larger in a direction away from the third inclined surface 1811. When the remote control lifeboat advances, the second propulsion device 4 works, water enters the second accommodating groove 18 from the second water inlet 19, in order to realize smoothness of water entering the second water inlet 19, a second diversion inner wall 181 opposite to the second water inlet 19 is provided, and after entering from the second water inlet 19, water flow firstly contacts with the third inclined surface 1811 and then contacts with the fourth inclined surface 1812, that is, the second diversion inner wall 181 formed by the third inclined surface 1811 and the fourth inclined surface 1812 provides a diversion structure for entering water flow, so that the water flow is convenient to enter the second accommodating groove 18 and move along the direction of the second propulsion device 4, and sufficient propulsion water flow is supplied for the second propulsion device 4 in real time. The vertical distance between the fourth inclined surface 1812 and the second water inlet 19 becomes gradually larger in a direction away from the third inclined surface 1811; so that a sufficient negative pressure can be created at the second water inlet 19 for the water flow into the second receiving tank 18, further ensuring that a sufficient propulsion water flow can be supplied in real time to the second propulsion device 4.
