Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to a device for controlling the idling of the stern shaft of a ship under static conditions. Background Technology

[0002] The key to controlling the stern shaft idler mechanism when a ship is in a static state is to ensure that the stern shaft sealing device maintains good sealing performance even when it is not in operation, in order to prevent lubricating oil leakage and environmental pollution.

[0003] However, it still has the following drawbacks in practical use:

[0004] During the maintenance of the existing tail shaft idling device, the power supply of the tail shaft idling device is fixedly installed at the installation location. The entire mounting frame needs to be disassembled and reassembled during the maintenance process, which is quite cumbersome and inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a device for controlling the stern shaft idle rotation of a ship under static conditions, so as to solve the problem mentioned in the background art that the power supply of the existing stern shaft idle rotation device is fixedly installed at the installation location, and the entire mounting frame of the device is cumbersome and inconvenient to disassemble and reassemble during maintenance.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a device for controlling the idling of a ship's stern shaft under static conditions, comprising a mounting frame and a housing. A guide frame is fixedly connected to one side of the mounting frame, and an engine is mounted below the mounting frame. A rotating rod is mounted on the output shaft of the engine via a coupling, and a blade is mounted on one end of the rotating rod. The device also includes an adjustment mechanism: the adjustment mechanism includes a connecting plate disposed inside the guide frame, a mounting rod mounted on the top of the connecting plate, and a threaded groove formed at the center of the upper part of the mounting rod, with a bolt threaded into the groove; and a noise reduction mechanism: the noise reduction mechanism is disposed on one side of the engine.

[0008] Furthermore, the noise reduction mechanism includes a fixed ring disposed on one side of the engine, with noise reduction grooves evenly distributed inside the fixed ring, and noise reduction blocks installed inside the noise reduction grooves. A buffer frame is installed at the rear end of the engine.

[0009] Furthermore, the buffer frame is irregularly shaped.

[0010] Furthermore, the number of noise reduction blocks is set to multiple groups.

[0011] Furthermore, there are two sets of guide frames, and a guide groove is provided on the inner side of the guide frame. Both ends of the connecting plate pass through the guide groove.

[0012] Furthermore, the outer surface of the bolt is uniformly provided with threads.

[0013] Furthermore, the mounting rod is shaped like a concave plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This utility model is equipped with an adjustment mechanism. After the operator installs the mounting bracket at the installation location, the bottom end of the bolt can be brought into contact with the ground by rotating the bolt. At the same time, the bolt drives the mounting rod connected to the outer surface threaded to rise and fall. Simultaneously, the mounting rod drives the connecting plate, which is fixedly connected at both ends, to slide on the inner side wall of the guide frame. A buffer bracket is installed at one end of the connecting plate, which can adjust the position of the engine. The device can be used flexibly according to the actual situation.

[0016] Based on the aforementioned beneficial effects, a noise reduction mechanism is provided. When the device is started, the starting engine drives a rotating rod fixedly connected to one end to rotate. At the same time, a fixed ring is fixedly connected to one side of the engine. As the rotating rod rotates, noise reduction blocks evenly fixedly connected to the inner side of the fixed ring reduce the noise generated by the rotation of the blades fixedly connected to one end of the rotating rod. Meanwhile, a buffer frame is fixedly connected to one end of the engine to mitigate water pressure impacts, thereby reducing the noise generated during device startup and extending the service life of the device.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment is a device for controlling the idling of the tail shaft of a ship under static conditions, including a mounting frame 1 and a housing 2. A guide frame 11 is fixedly connected to one side of the mounting frame 1. An engine 8 is installed below the mounting frame 1. A rotating rod 6 is installed on the output shaft of the engine 8 through a coupling. A blade 7 is installed at one end of the rotating rod 6. The device also includes an adjustment mechanism: the adjustment mechanism includes a connecting plate 12 disposed inside the guide frame 11. A mounting rod 3 is installed at the top of the connecting plate 12. A threaded groove is opened at the center of the upper part of the mounting rod 3. A bolt 4 is threadedly connected inside the threaded groove. A noise reduction mechanism is disposed on one side of the engine 8.

[0028] The adjustment mechanism, as the main load-bearing structure, can increase the overall flexibility of the structure by being fixedly connected to the device.

[0029] There are two sets of guide frames 11. The inner side of the guide frame 11 is provided with a guide groove, and both ends of the connecting plate 12 pass through the guide groove.

[0030] The guide groove allows the mounting rod 3 to be guided and raised / lowered.

[0031] The outer surface of bolt 4 is uniformly threaded.

[0032] The threaded design allows the mounting rod 3 to move up and down as the bolt 4 rotates.

[0033] Working principle: After the operator installs the mounting bracket 1 at the installation location, the bottom end of the bolt 4 can be made to contact the ground by rotating the bolt 4. At the same time, the bolt 4 drives the mounting rod 3 with the threaded connection on the outer surface to rise and fall. Simultaneously, the mounting rod 3 drives the connecting plate 12, which is fixedly connected at both ends, to slide on the inner side wall of the guide frame 11. The buffer bracket 5 is installed at one end of the connecting plate 12, which can adjust the position of the engine 8.

[0034] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and also includes a noise reduction mechanism. The noise reduction mechanism includes a fixing ring 9 disposed on one side of the engine 8. Noise reduction grooves are evenly opened inside the fixing ring 9. Noise reduction blocks 10 are installed inside the noise reduction grooves. A buffer frame 5 is installed at the rear end of the engine 8.

[0035] The buffer frame 5 is an irregularly shaped frame.

[0036] The irregular frame design can buffer the impact of water pressure.

[0037] Working principle: The engine 8 is started to drive the rotating rod 6, which is fixedly connected to one end, to rotate. At the same time, a fixed ring 9 is fixedly connected to one side of the engine 8. When the rotating rod 6 rotates, the noise reduction blocks 10, which are evenly fixedly connected to the inner side of the fixed ring 9, reduce the noise generated by the rotation of the blade 7, which is fixedly connected to one end of the rotating rod 6. Meanwhile, a buffer frame 5 is fixedly connected to one end of the engine 8 to relieve water pressure impact.

[0038] This step can reduce the noise generated when the device is started up, and at the same time extend the service life of the device.
