DETAILED DESCRIPTION

[0023] The present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0025] like Figure 1 to Figure 3 As shown, the present application designs a ship power system, including a propulsion system 1, wherein the propulsion system 1 includes a main engine, a transmission device 2 and a rotatable shaft 3. A plurality of blades 4 are arranged on the shaft 3 along the circumferential direction. The propulsion system 1 also includes a cleaning mechanism 5 for cleaning impurities on the surface of the blades 4. The cleaning mechanism 5 includes a connecting bar 503 fixed to the housing of the transmission device 2, and a rotating bar 501 is arranged on the side of the connecting bar 503 close to the blade 4. The rotating bar 501 is rotatably connected to the connecting bar 503 and fixed by a locking assembly, and a fixing block 504 is arranged at the other end of the rotating bar 501, and a cleaning frame 502 with an open end is arranged on the fixing block 504, and bristles 505 used in conjunction with the blade 4 are arranged on the opposite side walls inside the cleaning frame 502.

[0026] During use, when it is necessary to regularly clean dirt and other impurities on the surface of the blade 4, first release the locking assembly from fixing the rotating bar 501, and then rotate the rotating bar 501 until the cleaning frame 502 is located close to the rotating shaft 3, that is, the rotating blade 4 passes through the two rows of bristles 505 of the cleaning frame 502, and then the locking assembly is used to effectively fix the rotating bar 501. During the rotation of the blade 4, the bristles 505 effectively brush away dirt and other impurities on its surface. After the regular cleaning of impurities on the surface of the blade 4 is completed, the rotating bar 501 is reset to the initial position.

[0027] Preferably, the number of the blades 4 is multiple, such as three or four.

[0028] In addition, in order to prevent the cleaning efficiency of the bristles 505 from being greatly reduced and the cleaning effect from being unsatisfactory during the cleaning process, the present application also provides a maintenance structure for the bristles 505, such as Figure 3 As shown, the rotating shaft 3 is also provided with a combing plate 506 matched with the bristles 505, and two groups of comb strip rows are symmetrically arranged on the combing plate 506, and each group of comb strip rows includes a plurality of comb strips arranged in sequence and spaced apart.

[0029] By providing a combing plate 506 that cooperates with the cleaning mechanism 5, during the rotation of the blade 4, the bristles 505 effectively brush away dirt and other impurities on the surface of the blade 4, while the combing plate 506 effectively combs and maintains the bristles 505 to ensure the cleaning effect and cleaning efficiency of the bristles 505, thereby further improving the practicality and working reliability of the cleaning mechanism 5.

[0030] The following are examples of the present application:

[0031] Example 1

[0032] This embodiment is basically the same as the basic structure of the ship power system of the present application, and the difference lies in the specific structure of the locking assembly.

[0033] like Figure 1 and Figure 4As shown, in this embodiment, based on comprehensive considerations of cost, work reliability and ease of operation, the locking assembly adopts the following structure. The locking assembly includes a mounting block 508 fixed on the side wall of the rotating bar 501 and a plurality of plug holes 507 provided on the connecting bar 503 and distributed circumferentially along the rotating bar 501. The mounting block 508 is provided with a latch 509 that matches the size of the plug hole 507, and the latch 509 is slidably connected to the mounting block 508. The locking assembly also includes a first spring 511 sleeved on the latch 509 and a retaining ring 510 fixedly mounted on the latch 509. One end of the first spring 511 away from the connecting bar 503 is fixedly connected to the mounting block 508, and the other end is fixedly connected to the retaining ring 510. The elastic force of the first spring 511 is used to ensure that the pin 509 is stably inserted into the insertion hole 507 , that is, the retaining ring 510 drives the pin 509 to be stably inserted into the insertion hole 507 under the elastic force of the first spring 511 , thereby effectively fixing the rotating bar 501 .

[0034] In this embodiment, the first spring 511 is a constant force spring, which has the advantages of constant elastic force, stable and controlled movement, stable quality, strong durability, and long service life.

[0035] During use, when it is necessary to regularly clean dirt and other impurities on the surface of the blade 4, first pull the pin 509 outward until the pin 509 is out of the socket 507, and then rotate the rotating bar 501 to achieve the twisting work of the cleaning frame 502. When the cleaning frame 502 is rotated to a position close to the side of the rotating shaft 3, the pin 509 is released. At this time, the retaining ring 510 will drive the pin 509 to be inserted into the socket 507 under the elastic force of the first spring 511, and effectively fix the rotating bar 501 after rotation. The blade 4 is driven to rotate by the rotating shaft 3. During the continuous rotation process, dirt and other impurities on the surface of the blade 4 are brushed away by the bristles 505 on the cleaning frame 502. At the same time, the combing plate 506 effectively combs the bristles 505 to ensure the cleanliness and cleaning efficiency of the bristles 505, further improving the performance and practicality of the bristles 505. After the cleaning of the blade 4 is completed, the cleaning frame 502 is similarly reset to the side away from the rotating shaft 3 and fixed by the first spring 511 , the latch 509 and the socket 507 , so as to facilitate the normal operation of the blade 4 .

[0036] Example 2

[0037] This embodiment is basically the same as the basic structure of the ship power system of the present application, the difference being that a locking mechanism 6 is additionally provided.

[0038] like Figure 2 and Figure 5As shown, the propulsion system 1 of this embodiment further includes a locking mechanism 6 for effectively fixing the rotating shaft 3, the locking mechanism 6 includes a rectangular bar 61 fixed on the housing of the transmission device 2, the rectangular bar 61 is slidably connected with a rectangular frame 63, and a slot 62 for matching with the rectangular frame 63 is provided on the side wall of the rotating shaft 3. A second spring 64 is provided between the side of the rectangular frame 63 close to the rotating shaft 3 and the rectangular bar 61, and a locking rod 66 is hinged on the side of the rectangular frame 63 away from the rotating shaft 3, the locking rod 66 is an L-shaped structure, and an arc groove 65 for matching with the locking rod 66 is provided on the rectangular bar 61.

[0039] In this embodiment, the second spring 64 also adopts a constant force spring. The constant force spring has the advantages of constant elastic force, stable and controlled movement, stable quality, strong durability, and long service life.

[0040] During the long-term use of the blades 4, stubborn impurities that cannot be cleaned off by the bristles 505 are likely to appear on the surface thereof, and manual cleaning is required at this time. Based on this, the present embodiment adds the above-mentioned locking mechanism 6 that can effectively fix the rotating shaft 3 to ensure the stability of the rotating shaft 3 and the blades 4 when the staff performs strong cleaning work on the blades 4, greatly reducing safety hazards and the risk of damage to the rotating shaft 3 and the blades 4, thereby improving the cleaning effect and efficiency while ensuring the structural stability, working reliability and service life of the system.

[0041] During use, before manually removing stubborn impurities on the surface of the blade 4, the rotation of the shaft 3 is first stopped, and then the locking rod 66 is rotated until the locking rod 66 is rotated out from the inner side of the arc groove 65, that is, the locking rod 66 is disengaged from the arc groove 65, and then the locking rod 66 is released. The rectangular frame 63 moves toward the position of the shaft 3 under the elastic force of the second spring 64 on the rectangular bar 61 until it is inserted into the slot 62, thereby effectively fixing the shaft 3. At this time, manual cleaning work can be carried out.

[0042] After cleaning is completed, first pull the rectangular frame 63 outward until the rectangular frame 63 is out of the slot 62, then rotate the locking rod 66, and wait for the locking rod 66 to rotate into the arc groove 65, release the rectangular frame 63, and the locking rod 66 is stably locked in the arc groove 65 under the elastic force of the second spring 64, thereby effectively fixing the rectangular frame 63 and ensuring that the rectangular frame 63 is away from the slot 62 to avoid affecting the normal operation of the rotating shaft 3 and the paddle 4.

[0043] To sum up, this embodiment can effectively fix the rotating shaft 3 by setting the locking mechanism 6, so as to facilitate manual and vigorous cleaning of stubborn impurities on the surface of the blade 4, thereby improving the cleaning effect and efficiency while reducing safety hazards and the risk of damage to the rotating shaft 3 and the blade 4.
