Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a pointed and thin ship bottom telescopic push structure. Background Art

[0002] A retractable thruster is a common ship propulsion device, usually arranged at the bow of the ship. It is usually stored inside the bottom of the ship and can be extended from the bottom of the ship to provide power when needed.

[0003] Telescopic thrusters maximize their performance the closer they are to the bow. However, due to layout and construction space constraints, they are typically placed on the flat bow bottom area for ease of installation. However, for certain vessels, the tight bow space demands both operational and placement requirements for telescopic thrusters and structural strength. Conventional telescopic thruster placement and structural support methods cannot address these challenges.

[0004] In existing technology, telescopic pushers are typically placed on a flat surface on the ship's bottom to facilitate connection between the guide post base and the hull's support structure, ensuring sufficient strength to support the operation of the telescopic pusher. The telescopic pusher guide post is typically placed at the front (near the bow), with the guide post base horizontal and connected to the ship's support structure. However, for ships with limited bow space, this lacks the space required for the guide post to be placed forward. Furthermore, the limited space on the flat bow makes it difficult for the guide post base to connect to the hull structure, resulting in a lack of support strength.

[0005] The disadvantages of the existing telescopic pusher layout are: it takes up a lot of space, has high requirements for the spatial layout of ships / offshore structures, and requires adjustments to the ship's lines or dimensions for the layout of some ship types, which has an adverse impact on the overall performance and cost of the ship. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art and provide a pointed and thin ship bottom telescopic pusher structure.

[0009] Furthermore, the transverse supports are plate-shaped and are distributed along the transverse direction of the ship.

[0010] Further, the lateral support member is a vertical plate; the connection between the lateral support member and the bulkhead of the thruster compartment is vertically distributed.

[0011] Further, a first reinforcing member is fixedly provided at a corresponding position on the outer side of the bulkhead of the thruster compartment at the connection between the lateral support member and the bulkhead of the thruster compartment.

[0013] Further, the longitudinal support member is a vertical plate, and the connection between the longitudinal support member and the bulkhead of the thruster compartment is vertically distributed.

[0014] Further, a second reinforcing member is fixedly provided at a corresponding position on the outer side of the bulkhead of the thruster compartment at the connection between the longitudinal support member and the bulkhead of the thruster compartment.

[0015] Further, both the lateral support member and the longitudinal support member are triangular plates.

[0016] Further, a working hole for the propeller of the retractable thruster to enter and exit is opened on the bottom plate of the ship below the thruster compartment, and the guide post bottom plate extends into the working hole, and the part of the guide post bottom plate extending into the working hole matches the ship outer plate line around the working hole.

[0017] Further, the guide post bottom plate is fixedly provided on the bulkhead of the thruster compartment at the same time.

[0024] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a pointed and slender ship bottom telescopic propulsion structure form includes a propulsion nacelle 10 provided with a telescopic thruster 11. The propulsion nacelle is arranged at the bow of the ship, and a guide post 20 is arranged in the propulsion nacelle 10.

[0026] The guide post 20 is arranged behind the propeller 14 of the telescopic thruster 11. In the field of ship technology, the bow is the front and the stern is the rear.

[0027] The bottom of the guide post 20 is fixedly provided with a guide post bottom plate 21. The guide post bottom plate 21 is simultaneously fixedly arranged on the bulkhead 12 of the propulsion nacelle.

[0028] A transverse support member 30 and a longitudinal support member 40 are fixedly arranged on the guide post bottom plate 21; both the transverse support member 30 and the longitudinal support member 40 are fixedly connected to the bulkhead 12 of the propulsion nacelle.

[0029] The transverse support member 30 is plate-shaped and is distributed along the transverse direction of the ship. The transverse support member 30 is a vertical plate; the connection part between the transverse support member 30 and the bulkhead 12 of the propulsion nacelle is vertically distributed.

[0030] A first strengthening member 31 is fixedly arranged at the corresponding position on the outer side of the bulkhead 12 of the propulsion nacelle at the connection part between the transverse support member and the bulkhead of the propulsion nacelle.

[0031] The longitudinal support member 40 is plate-shaped and is distributed along the longitudinal direction of the ship.

[0032] The longitudinal support member 40 is a vertical plate, and the connection part between the longitudinal support member 40 and the bulkhead 12 of the propulsion nacelle is vertically distributed.

[0033] A second strengthening member 41 is fixedly arranged at the corresponding position on the outer side of the bulkhead 12 of the propulsion nacelle at the connection part between the longitudinal support member and the bulkhead of the propulsion nacelle.

[0034] Both the transverse support member and the longitudinal support member are triangular plates.

[0035] On the bottom plate 15 below the thruster compartment 10, a working hole 13 is provided for the propeller of the retractable thruster to enter and exit. The guide post bottom plate 21 extends into the working hole, and the part of the guide post bottom plate extending into the working hole matches the ship's outer plate line type around the working hole. As Figure 5 shown.

[0036] It should be noted that in order to clearly show the internal structure of the thruster compartment, the retractable thruster is not shown in Figure 2 . In addition, Figure 1 is a structural diagram of the midship longitudinal section position of the ship.

[0037] The slender ship bottom retractable thruster structure of the present utility model utilizes the space of the original structure of the ship / marine structure. It does not require the bottom of the bow to be completely horizontal and can be arranged in the slender area at the bow, with more flexible arrangement.

[0038] According to the characteristics of the ship's line type, the bottom of the ship at the rear end (far from the bow) of the thruster compartment is relatively flat. Therefore, the guide post of the retractable thruster is placed at the rear end of the cavity, making reasonable use of the space at the bow of the ship.

[0039] For ships with a tight bow space, it is difficult for the guide post bottom plate to be connected to the strong structure of the ship. Relying only on the support of the ship's outer plate is difficult to meet the strength requirements. Therefore, the guide post bottom plate is connected to the strong structure of the ship through the cantilever beam type transverse support member and longitudinal support member, providing transverse and longitudinal constraints and effectively ensuring the support strength.

[0040] The opening at the linear position at the bottom of the bow will affect the ship's resistance. To reduce the resistance, the part of the guide post bottom plate extending into the working hole matches the ship's outer plate line type around the working hole, and the guide post bottom plate matches the bow line type, which can not only ensure the integrity of the ship structure but also provide a basis for the setting of the support structure.

[0041] The present utility model has the following advantages:

[0042] 1. The present utility model is applicable to the reverse arrangement of the retractable thruster suitable for the bow space characteristics and can make reasonable use of the original space of the structure.

[0043] 2. The retractable thruster guide post bottom plate matches the ship's outer plate line type, ensuring the continuity of the bottom structure of the ship and reducing the ship's resistance.

[0044] 3. The cantilever support structure composed of the transverse support member and longitudinal support member can effectively ensure the support strength.

[0045] 4. Under the condition of limited bow scale, there is no need to adjust the ship scale, ensuring the overall performance of the ship.

[0046] 5. The structure is simple and the construction is convenient, without increasing additional workload, improving the economy and effectively solving the contradiction between supply and demand.

[0047] The pointed and slender bottom telescopic push structure of the present utility model overcomes the defects of the prior art, has low requirements for layout space, and can be widely applied to compact ships / offshore structures, avoiding additional costs.

[0048] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present utility model.
