DETAILED DESCRIPTION

[0029] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0030] Embodiment 1:

[0031] The embodiment of the present application discloses an oar lifting device which can make the ship body pass through the rope net water area smoothly. Referring to Figure 1 The oar lifting device which can make the ship body pass through the rope net water area smoothly comprises a lifting support 1 and a driving oar 2.

[0032] Referring to Figure 1 and Figure 2The lifting support 1 comprises a horizontal rod body 11 and an inclined rod body 12. The horizontal rod body 11 is used to mount the lifting support 1 to the ship body. In the embodiment 1, the fixed end of the horizontal rod body 11 is mounted to the tail of the ship body, and the free end of the horizontal rod body 11 is cantilevered behind the ship body. The inclined rod body 12 is fixedly mounted to the top of the horizontal rod body 11, and is inclined from bottom to behind the ship body, so that the included angle between the horizontal rod body 11 and the inclined rod body 12 is obtuse. In addition, a reinforcing rib 13 is arranged between the horizontal rod body 11 and the fixed rod body. The bottom of the reinforcing rib 13 is fixedly connected to the horizontal rod body 11, and the top of the reinforcing rib 13 is fixedly mounted to the inclined rod body 12, so as to increase the connection strength between the inclined rod body 12 and the horizontal rod body 11 through the reinforcing rib 13.

[0033] With reference to Figure 1 and Figure 2 The fixed end of the driving oar 2 is rotatably connected to the lifting support 1. When the driving oar 2 is rotated to the vertical state, the oar blade of the driving oar 2 is located at the bottom of the ship body. The top of the inclined rod body 12 is fixedly mounted with two fixed pulleys 121, which are distributed along the width direction of the ship body. The movable pulley is fixedly arranged at the free end of the driving oar 2, and is away from the connection between the driving oar 2 and the lifting support 1. The oar pulling rope 3 is wound between the fixed pulleys 121 and the movable pulley. The fixed end of the oar pulling rope 3 is fixedly mounted to the horizontal rod body 11, and the oar pulling rope 3 is sequentially wound on one of the fixed pulleys 121, the sliding pulley 21 and the other fixed pulley 121. In this way, by pulling the free end of the oar pulling rope 3, the oar pulling rope 3 is rotated around the fixed pulleys 121 and the sliding pulley 21, thereby saving the strength required for rotating and lifting the driving oar 2, so as to facilitate the crew to lift the driving oar 2. In addition, the horizontal rod body 11 is fixedly mounted with two oar rope fixing ears 111. One of the oar rope fixing ears 111 is used for connecting the fixed end of the oar pulling rope 3, and the other oar rope fixing ear 111 is used for connecting the free end of the oar pulling rope 3. In this way, after the crew lifts the driving oar 2, the oar pulling rope 3 is fixedly wound on the oar rope fixing ear 111, so as to reduce the situation that the crew pulls the oar pulling rope 3 for a long time.

[0034] With reference to Figure 2 The driving oar 2 is provided with a steering oar 22. One end of the steering oar 22 is rotatably connected to the driving oar 2, and the other end of the steering oar 22 is located in front of the oar blade of the driving oar 2, so as to change the direction of the ship body by rotating the steering oar 22. The steering oar 22 is provided with two weight-reducing holes 221, so as to facilitate the crew to rotate the steering oar 22 in time by overcoming the inertia of the steering oar 22.

[0035] The embodiment 1 of the application discloses a propeller lifting device for smoothly passing through a rope net water area. When passing through the rope net water area, a crew member pulls the free end of the propeller pulling rope 3, so that the propeller pulling rope 3 moves around the fixed pulley 121, the movable pulley and the other fixed pulley 121 in turn, and then lifts the driving propeller 2 from the water, so that the driving propeller 2 is not easily stuck by underwater or water surface sundries, and the propeller pulling rope 3 is used to reduce the force required for lifting the driving propeller 2, so that the crew member can easily lift the propeller.

The bottom of the horizontal rod body 11 is fixedly installed with a horizontal sliding block 112, and the horizontal sliding block 112 is slidably matched with the adjusting slide rail 4 in the horizontal direction, so that the lifting support 1 and the driving propeller 2 can be slidably stored in the interior of the ship body in the horizontal direction, the collision between the driving propeller 2 and the wharf or the shore is reduced, and the ship body can be quickly towed away from the rope net area.

[0039] Referring to Figure 3 , the lifting support 1 is provided with a plurality of support fixing holes 101, the adjusting slide rail 4 is provided with a plurality of slide rail fixing holes 401, and the lifting support 1 is further installed on the adjusting slide rail 4 through a locking handle 5 which is slidably arranged in the support fixing hole 101 and threadedly matched with the slide rail fixing hole 401, so that after the driving propeller 2 is slid to the required position, the driving propeller 2 can be stably locked at the required position by rotating the locking handle 5.
