Description

Technical Field

[0001] The embodiments of this specification relate to the technical field of ship propulsion, and particularly to a ship propulsion device. Background Art

[0002] A ship propulsion device refers to a power device used to propel a ship forward. As an important power device, a podded propeller is usually directly connected to the bottom of the ship's cabin. It converts the power generated by the engine into thrust, thereby driving the hull forward.

[0003] However, this traditional connection method has significant drawbacks, namely, drilling operations need to be carried out on the bottom of the ship's cabin. First of all, the drilling operation provides a potential channel for water to enter the cabin. Since the bottom of the cabin is often in an underwater environment, the presence of the drilling holes allows seawater to potentially enter the cabin through these holes. This will not only damage the equipment on the ship, but more importantly, pose a great threat to the personal safety of the ship's crew. Once water enters the cabin, it may cause the ship to lose stability and even lead to serious accidents such as capsizing. Secondly, the bottom of the ship's cabin is an important part of the hull. It bears the weight of the hull and maintains the stability of the hull. Drilling holes in the bottom of the cabin will damage the integrity of the hull structure, may lead to a reduction in the hull strength, and thus affect the overall safety performance of the ship.

[0024] Hereinafter, a ship propulsion device according to an embodiment of this specification will be described in detail with reference to the drawings. Figure 1The structural schematic diagram of a ship propulsion device of an embodiment of the present specification is shown. A ship propulsion device of the embodiment of the present specification comprises: a pod propulsion device 1, a steering mechanism, a supporting mechanism and a fixing mechanism 4; the supporting mechanism comprises a first supporting plate 31 and a second supporting plate 32, the second supporting plate 32 is vertically arranged above one side of the first supporting plate 31; the pod propulsion device 1 is arranged at the bottom of the first supporting plate 31; the steering mechanism comprises a steering rod 21 and a steering rudder 22, the other side of the first supporting plate 31 is sleeved outside the steering rod 21, and the steering rudder 22 is arranged on the propeller side of the pod propulsion device 1; the fixing mechanism 4 is arranged on the second supporting plate 32, and the ship propulsion device is clamped on the stern plate by tightening the fixing mechanism 4 toward the second supporting plate 32 side.

[0025] A ship propulsion device of this embodiment only needs to be installed on the stern board, and the rest of the device is not connected to the cabin, and there is no need to drill holes in the bottom of the cabin, so water cannot enter the cabin, which increases the service life of the ship while ensuring the personal safety of the personnel on board. A ship propulsion device of this embodiment is suitable for low-power pod propellers, and its power requirement is less than 6000 watts. Connect the phase line of the pod propeller 1 to the driver, and the driver is controlled by the accelerator lever of the controller. Turn on the power, push the accelerator lever of the controller, and the pod propeller 1 can propel the ship forward.

[0026] The fixing mechanism 4 includes a hand piece 41, a screw 42, a resistance piece 43 and a fixing piece 44. The fixing piece 44 is arranged on the second support plate 32, the screw 42 passes through the fixing piece 44, and the hand piece 41 and the resistance piece 43 are respectively arranged on both sides of the screw 42. When the hand piece 41 is rotated so that the screw 42 is screwed in the direction of the transom, the resistance piece 43 and the second support plate 32 are tightly attached to both sides of the transom, and the ship propulsion device is clamped on the transom. Among them, the fixing piece 44 includes a transverse plate vertically attached to the second support plate and a screw fixing piece arranged perpendicular to the transverse plate, a screw hole matching the screw 42 is arranged in the screw fixing piece, and the screw 42 is vertically attached to the vertical rod through the screw hole, and the transverse plate is respectively fixed to the second support plate and the vertical rod through reinforcing ribs and fully welded, so that the ship propulsion device can withstand a large load. The hand-held member 41 is a handle, and the abutment member 43 is a foot cup, and the handle and the foot cup are respectively fixed at two ends of the screw rod 42. By rotating the handle, the distance between the foot cup and the second support plate 32 can be increased, and the ship propulsion device can be installed by clamping the stern plate between the foot cup and the second support plate 32.

[0027] Figure 2The figure shows a schematic side view structure of a ship propulsion device according to an embodiment of the present specification. Considering that the installation of the ship propulsion device is achieved only through a fixing mechanism and the second support plate 32, there may be a situation where the ship propulsion device cannot be stably clamped and cannot bear the weight of the ship propulsion device. Further, third support plates 33 identical to the second support plate 32 are symmetrically provided above the same side of the first support plate 31. Fixing mechanisms 4 are provided on both the third support plate 33 and the second support plate 32. The ship propulsion device is clamped to the stern plate through the second support plate 32, the third support plate 33 and the corresponding fixing mechanisms 4 respectively. One side of the third support plate 33 and one side of the second support plate 32 are fixedly connected to both ends of the first support plate 31 through reinforcing ribs and are fully welded, so that the ship propulsion device can bear a large load.

[0028] A through hole matching the pod thruster 1 is provided on the first support plate 31. A waterproof bucket 34 is provided on the through hole. The waterproof bucket 34 and the through hole are sealed with glass glue to prevent water from entering the pod thruster 1 through the through hole. The support mechanism further includes a fourth support plate 35 provided on the side wall of the waterproof bucket 34. One side of the fourth support plate 35 is sleeved outside the steering rod 21 of the steering mechanism.

[0029] The first support plate 31 and the fourth support plate 35 are arranged in parallel. A connecting plate 36 is provided between the first support plate 31 and the fourth support plate 35. The connecting plate 36 is used to strengthen the overall structural strength of the ship propulsion device and support the fourth support plate 35 and the steering mechanism. A limiting member 37 is provided on the connecting plate. A limiting groove 211 is provided on the steering rod 21. One side of the limiting member 37 is inserted into the limiting groove 211. The steering rod 21 rotates within the rotation angle range defined by the limiting groove 211. To control the weight and cost of the ship propulsion device, the length of the first support plate 31 is not designed to be too long, which will result in a relatively short distance between the propeller of the pod thruster 1 and the steering rudder 22. The steering rudder 22 is used to reduce water resistance and steer. If the steering rudder 22 makes a 360° turn, the propeller of the pod thruster 1 is easily damaged during the turning process of the steering rudder 22. Therefore, on the basis of meeting the steering requirements, a limiting groove 211 is provided on the steering rod 21 to enable the steering rudder 22 to make a 150° turn. It should be noted that one side of the limiting member 37 is inserted at the mid-axis of the limiting groove 211. Among them, 75° is for clockwise turning and 75° is for counterclockwise turning, restricting the turning angle of the steering rudder 22 and avoiding damage to the propeller of the pod thruster 1 caused by excessive turning of the steering rudder 22.

[0030] For the convenience of steering the steering rudder 22, the upper end of the steering rod 21 is vertically connected to the steering cross bar 212 through a connecting member 213. By rotating the grip of the steering cross bar 212, the steering rod 21 is driven to rotate the steering rudder 22. A screw hole is provided in the connecting member 213, and threads matching the screw hole are provided on the steering rod 21 and the steering cross bar 212. The steering rod 21 and the steering cross bar 212 are fixed in the screw hole of the connecting member 213 through the threads.

[0031] Flanges 214 are provided on the steering rod 21 at the joints with the first support plate 31 and the fourth support plate 35, which are used to prevent the steering rod 21 from sliding up and down in the through holes of the first support plate 31 and the fourth support plate 35.

[0032] Grooves are provided at the adjacent ends of the flange 214 and the first support plate 31 and the third support plate 33, and thrust ball bearings are provided in the grooves. The setting of the thrust ball bearings makes the steering operation more labor-saving.
