Description

Technical Field

[0001] The utility model belongs to the technical field of propellers, and in particular relates to a marine propeller. Background Art

[0002] Marine electric propulsion is an energy converter that overcomes the resistance of a ship sailing in the water and propels the ship forward. Marine electric propulsion is usually installed at the bow or stern. Some boats have narrow bows and sterns, so there is not enough space for personnel to operate the marine electric propulsion. It is impossible for personnel to stand next to the marine electric propulsion and hold the switch and support pole to lower and retract it, such as kayaks, fishing boards and other slender boats.

[0003] Among the existing marine electric propellers, some use belt transmission to achieve the retraction and extension of the electric propeller, but the belt is prone to aging after long-term use; and due to the complex environment such as the ocean or lake, small gravel, crushed stone or sand and other foreign objects enter the belt, resulting in the belt being stuck by gravel or sand and other foreign objects during the retraction and extension of the electric propeller and unable to continue to complete the retraction and extension action. Once a failure occurs, it will not only affect the use but also increase the time and cost of maintenance; others use gear transmission to achieve the retraction and extension of the electric propeller. For example, the patent application number is CN202221331942.4, and the patent name is a marine electric propeller, in which the lifting sleeve is mounted on the outside of the connecting shaft, and the inner side of the lifting sleeve is provided with lifting spiral teeth, which mesh with the spiral teeth on the outer side of the connecting shaft, resulting in incomplete sealing. Gravel or other foreign objects are easy to enter the gear transmission position, which is easy to cause the gear to get stuck and unable to be retracted and extended, and may also cause wear and scratches on the gear. Some foreign objects contain corrosive substances, which may cause the parts in the gear box to rust and corrode, resulting in reduced performance of the gear box, thereby affecting the service life of the equipment.

[0051] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0052] The utility model relates to a marine propeller, such as Figure 1-7 As shown, it includes a thruster body 1, and also includes: a bracket 2, the thruster body 1 is rotatably connected to the bracket 2; a flip assembly 3, which is movably arranged relative to the bracket 2, and the flip assembly 3 has a connecting end connected to the thruster body 1, and has a locking end configured to be able to lock with the bracket 2 after the thruster body 1 is rotated at a preset angle relative to the bracket 2; a handle assembly 5, the handle assembly 5 is connected to the flip assembly 3, can drive the locking end of the flip assembly 3 to unlock the bracket 2, and is used to drive the thruster body 1 to turn relative to the bracket 2.

[0053] The bracket 2 serves as a structure for supporting the propeller body 1 and can support the propeller body 1 on the stern board; the flip assembly 3 can move relative to the bracket 2, and the flip assembly 3 is connected to the propeller body 1, so that the flip assembly 3 can drive the propeller body 1 to move relative to the bracket 2 to achieve the steering action of the propeller body 1; the flip assembly 3 also has a locking end that can be locked with the bracket 2, so that after the flip assembly 3 drives the propeller body 1 to rotate a certain angle relative to the bracket 2, it can be locked with the bracket 2 through the locking end, so that the propeller body 1 is positioned at the required steering angle; by providing a handle assembly 5 connected to the flip assembly 3, the purpose of driving the flip assembly 3 is achieved, and the locking end of the flip assembly 3 locked with the bracket 2 can be unlocked from the bracket 2. After unlocking, the handle assembly 5 connected to the propeller body 1 drives the propeller body 1 to turn relative to the bracket 2, thereby further realizing the retracting and releasing action.

[0054] Through the arrangement of the handle assembly 5, the flip assembly 3 and the bracket 2, the present application only needs to remotely operate the handle assembly 5 to realize the operation of retracting and extending the thruster body 1, and there is no need to get close to the thruster body 1 to realize the steering operation. It is especially suitable for realizing the retracting and extending action in environments such as slender and narrow ships that do not have operating space. Moreover, the material used in the present application is resistant to aging, and will not get stuck or the controller malfunction due to external factors during use, thus avoiding the situation where retraction and extension are difficult or impossible. The operation is simple and convenient, and can achieve rapid retraction and extension.

[0055] As a preferred embodiment, Figure 3 and Figure 4 As shown, the flip assembly 3 includes a wrench member 31, a thrust member 32 and a locking member 33; the wrench member 31 is connected to the handle assembly 5, and the wrench member 31 is provided with the connecting end connected to the thruster body 1; the thrust member 32 is connected between the wrench member 31 and the locking member 33, one end of the thrust member 32 is rotatably connected to the wrench member 31, and the other end of the thrust member 32 is connected to the thruster body 1 through a spring 19; the locking member 33 is connected to the thrust member 32, and the locking member 33 is provided with the locking end locked and connected to the bracket 2.

[0056] Specifically, Figure 7The position shown is described as follows: the spring 19 is connected to a connecting shell 4 that can be connected to the thruster body 1; the top end of the thrust piece 32 is rotatably connected to the wrench piece 31; the bottom end of the thrust piece 32 can be connected to the connecting shell 4 through the spring 19; a connecting shaft is provided at the middle position of the connecting shell 4; one end of the spring 19 is connected to the connecting shaft; the other end of the spring 19 can be connected to the thrust piece 32, so that when the handle assembly 5 is pressed, the wrench piece 31 is driven to rotate. At this time, the spring 19 between the thrust piece 32 and the connecting shell 4 is compressed. When the locking end of the locking piece 32 is rotated to the stop opening 13 of the bracket plate 21 described below, the spring force acting between the thrust piece 32 and the connecting shell 4 can drive the thrust piece 32 and the locking end of the locking piece 33 connected to the thrust piece 32 to engage with the stop opening 13, thereby realizing the locking between the locking piece 33 and the bracket plate 21.

[0057] The wrench piece 31 is connected to the handle assembly 5, and the handle assembly 5 drives the wrench piece 31 to rotate, so that the wrench piece 31 drives the thrust piece 32 and the locking piece 33 to rotate relative to the bracket 2. Since the locking piece 33 has a locking end that is locked and connected to the bracket 2, when the handle assembly 5 drives the wrench piece 31 to rotate, the locking end of the locking piece 33 can be unlocked from the bracket 2, and the handle assembly 5 can directly drive the propeller body 1 to turn relative to the bracket 2. After the propeller body 1 rotates a certain angle relative to the bracket 2, the handle assembly 5 releases the wrench piece 31 of the flip assembly 3 to further drive the locking end of the locking piece 33 to lock relative to the bracket 2, thereby achieving the fixation between the propeller body 1 and the bracket 2 after adjusting the steering angle.

[0058] It is worth noting that in this embodiment, the connecting shell 4 is a partial structure of the propeller body 1. The connecting shell 4 is a part of the propeller body 1 described below, and the specific detailed structure is specifically involved in the control box 12 described below.

[0059] As a preferred embodiment, Figure 3 As shown, the flip assembly 3 also includes a connecting shell 4, which is connected to the thruster body 1, and the other end of the thrust member is connected to the connecting shell through a spring, and the connecting end of the wrench member 31 is rotatably connected to the connecting shell 4.

A through hole is opened in the connecting shell 4 for passing the propulsion shaft 11 described below of the propeller body 1. The connecting end of the wrench member 31 is connected to the connecting shell 4, so that the wrench member 31 can rotate relative to the connecting shell 4. By rotating the wrench member 31, the locking end of the locking member 33 connected to the wrench member 31 is unlocked from the bracket 2, and then the wrench member 31 is loosened so that the locking end connected to the wrench member 31 cooperates with the stop opening 13 described below to lock the locking member 33 and the bracket 2.

[0061] It is worth noting that in this embodiment, the connecting shell 4 is a partial structure of the flip assembly 3 and is connected to the thruster body 1 via the connecting shell 4 , so that the thrust member 32 is elastically connected to the thruster body 1 .

[0062] Regarding the handle assembly 5, the specific structure of the handle assembly 5 may not be limited by the present application, and any of the following implementations may be adopted:

The thruster body 1 is connected to the clamp 54, and the clamp 54 has a first through hole and a second through hole. The first connecting rope 52 passes through the first through hole to be connected to the wrench member 31, and the second connecting rope 53 is connected to the second through hole through a hook.

[0064] like Figure 1As shown, it can be known from the following description that the propeller body 1 includes a propulsion shaft 11, one end of the propulsion shaft 11 in the axial direction is connected to the machine head 17, a bearing is connected to the side of the propulsion shaft 11 close to the machine head, a bearing cover connected to the bearing is arranged on the outer side of the bearing, a clamp 54 is arranged in the circumferential direction of the bearing, a protrusion is arranged on one side in the radial direction of the clamp 54, and a first through hole and a second through hole are arranged in parallel on the protrusion, the purpose of the first through hole is to enable the first connecting rope 52 to pass through the first through hole and connect with the wrench member 31, so as to use it as a connecting fulcrum between the handle 51 and the wrench member 31, thereby increasing the connection strength between the handle 51 and the wrench member 31 and improving the ability to pull the wrench member 31; the second The purpose of the through hole is to be able to clamp and connect the second connecting rope 53 in the second through hole, so as to realize the connection between the second connecting rope 53 and the handle 51 and the propulsion shaft 11 described below. When, under the action of the first connecting rope 52, the handle 51 pulls the wrench through the first connecting rope 52 to unlock the locking end of the locking member 33 and the bracket 2, the propulsion shaft 11 is pulled by the pulling action of the second connecting rope 53 to drive the entire propeller body 1 to rotate relative to the bracket 2. After rotating a certain angle, release the handle 51, release the first connecting rope 52 to release the pulling of the wrench member 31, thereby realizing the locking of the locking end of the locking member 33 and the bracket 2, thereby completing the turning operation of the propeller body 1 relative to the bracket 2.

The first semicircular hole and the second semicircular hole are connected to form the mounting groove 15 for installing the fixing knob 16. The mounting groove 15 is provided with a nut, which is convenient for the screw rod and the inner nut described below of the fixing knob 16 to be threadedly connected, so that the screw rod slides along the mounting groove 15 to adjust the spacing between the positioning block connected with the screw rod and the stern plate.

[0076] The fixing knob 16 includes a rotating handle, a spiral rod and a positioning block. The rotating handle is connected to one end of the spiral rod in the extension direction, and the other end of the spiral rod in the extension direction is connected to the positioning block. When in use, the spiral rod is directly installed in the mounting groove 15 from the lower part of the mounting groove 15, and then the mounting block is connected to the connecting plate 22 by bolts, and then the position is adjusted in the mounting groove 15 by screwing the spiral rod, so that the spacing between the mounting block and the stern plate is adjusted, so that the mounting block can clamp the stern plate, thereby strengthening the connection strength between the stern plate and the bracket plate 21, and preventing the bracket 2 from shaking or deflecting on the stern plate.
