Description

Technical Field

[0001] This utility model relates to the field of thruster fairing technology, specifically a fairing structure for a bow thruster of a bulk carrier. Background Technology

[0002] A bow thruster is a propulsion auxiliary device installed at the bow (forehead) of a bulk carrier or other vessel. Its main function is to generate lateral thrust through the rotation of a built-in propeller, helping the vessel to achieve precise maneuverability in scenarios such as low-speed navigation, berthing and unberthing in port, turning in narrow channels, or turning on the spot. It is usually arranged laterally inside the hull at the bow. When working, it draws in water from one side of the ship and discharges it from the other side, using the reaction force of the water flow to generate lateral thrust, thereby compensating for the lack of maneuverability of the main propeller at low speeds. Therefore, a fairing structure for a bow thruster of a bulk carrier is also required.

[0003] Existing fairings mostly adopt simple cylindrical or conical designs, which have problems such as high water flow resistance and poor flow guidance effect, resulting in low propulsion efficiency of the side thrusters, thus affecting the ship's maneuverability and stability. Utility Model Content

[0004] The purpose of this utility model is to provide a fairing structure for the bow thruster of a bulk carrier, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fairing structure for a bow thruster of a bulk carrier, comprising a fairing body,

[0006] A mounting block that is fixedly installed on the side wall of the air deflector body;

[0007] And a flow guiding assembly disposed on the side of the flow guide body;

[0008] The flow guiding assembly includes a flow guiding mechanism disposed on the inner wall of the flow guiding cover body;

[0009] An auxiliary mechanism is provided on the side of the fairing body.

[0010] Preferably, there are four mounting blocks, all of the same shape and size, and the four mounting blocks are equidistantly distributed on the four sides of the fairing body, which allows for quick installation of the fairing body.

[0011] Preferably, the flow guiding mechanism includes a stabilizing frame, which is fixedly installed on the inner wall of the flow guide body. A flow guide plate is rotatably installed on the inner wall of the stabilizing frame via a bearing. An adjusting rod is slidably installed on the inner wall of the flow guide plate with a groove at its top. An adjusting plate is fixedly installed on the top of the adjusting rod. An L-shaped support plate is fixedly installed on the top of the adjusting plate. A positioning bolt is rotatably installed on the inner wall of the L-shaped support plate. One end of the positioning bolt extends movably through the inner wall of the L-shaped support plate to the inner wall of the stabilizing frame with a positioning hole at its top.

[0012] Preferably, the bottom of the positioning bolt is threaded to the inner wall of the positioning hole, and the positioning holes are equidistantly distributed at the top of the stabilizing frame.

[0013] Preferably, there are five adjusting rods, which are equidistantly distributed at the bottom of the adjusting plate.

[0014] Preferably, the auxiliary mechanism includes a fixed rod and an arc-shaped guide plate. The fixed rod is fixedly installed on the inner wall of the guide plate body, a drive motor is fixedly installed on the side wall of the fixed rod, a rotating block is fixedly installed at the output end of the drive motor, and a propeller is fixedly installed on the side wall of the rotating block.

[0015] Preferably, the arc-shaped guide plate is fixedly installed on the inner wall of the guide shroud body, and there are multiple arc-shaped guide plates.

[0016] This utility model provides a fairing structure for the bow thruster of a bulk carrier. It has the following beneficial effects:

[0017] (1) When the operator operates the device, the angle of the guide plate can be adjusted according to the operator's needs. First, the position of the positioning bolt is rotated. When one end of the positioning bolt is disengaged from the inside of the stable frame, the position of the L-shaped support plate can be slid. The L-shaped support plate drives the position of the adjustment plate and the adjustment rod to move. The adjustment rod will slide to the inner wall of the flower-shaped opening at the top of the guide plate, effectively adjusting the angle of the guide plate. Then, the position of the positioning bolt is rotated again, causing the bottom of the positioning bolt to enter the inner wall of the positioning hole, thereby limiting the position of the guide plate, improving the guiding effect of the device, and further improving the stability of the ship. This solves the problem that the existing guide shields mostly adopt simple cylindrical or conical designs, which have large water flow resistance and poor guiding effect, resulting in low propulsion efficiency of the side thruster, thus affecting the maneuvering stability of the ship.

[0018] (2) The present invention can install the position of the guide shield body by means of mounting block and screw, the fixing rod supports the position of the drive motor, the drive motor can drive the position of the propeller and the rotating block to rotate, effectively playing the role of pushing the flow, and the guide shield body set on the inner wall of the guide shield body can play the role of guiding the flow.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] Example 1: A preferred embodiment of the fairing structure for the bow thruster of a bulk carrier provided by this utility model is as follows: Figures 1 to 4 As shown: A fairing structure for a bow thruster of a bulk carrier, comprising a fairing body,

An adjusting rod 413 is slidably installed on the inner wall of the flow guide plate 412 with a groove on its top. An adjusting plate 414 is fixedly installed on the top of the adjusting rod 413. An L-shaped support plate 415 is fixedly installed on the top of the adjusting plate 414. A positioning bolt 416 is rotatably installed on the inner wall of the L-shaped support plate 415. One end of the positioning bolt 416 extends through the inner wall of the L-shaped support plate 415 to the inner wall of the stabilizing frame 411 with a positioning hole on its top.

[0031] In this embodiment, the bottom of the positioning bolt 416 is threaded to the inner wall of the positioning hole, and the positioning holes are equidistantly distributed at the top of the stabilizing frame 411.

The L-shaped support plate 415 drives the adjustment plate 414 and the adjustment rod 413 to move. The adjustment rod 413 slides on the inner wall of the top opening of the guide plate 412, effectively adjusting the angle of the guide plate 412. Then, the positioning bolt 416 is rotated again, causing the bottom of the positioning bolt 416 to enter the inner wall of the positioning hole, thereby limiting the position of the guide plate 412, improving the guiding effect of the device, and further improving the stability of the ship.

A rotating block 424 is fixedly installed at the output end of the drive motor 425. A propeller 423 is fixedly installed on the side wall of the rotating block 424.

[0035] In this embodiment, the arc-shaped guide plate 421 is fixedly installed on the inner wall of the guide shroud body 1, and there are multiple arc-shaped guide plates 421.

[0036] In the specific implementation process, the position of the guide shield body 1 can be installed by the mounting block 2 in conjunction with screws. The fixing rod 422 supports the position of the drive motor 425. The drive motor 425 can drive the propeller 423 and the rotating block 424 to rotate, effectively playing the role of propulsion. The guide shield body 1 set on the inner wall of the guide shield body 1 can play the role of guiding the flow.
