Description

Technical Field

[0001] The utility model relates to a pod slip ring rotor, in particular to a pod slip ring rotor wiring connection drum. Background Art

[0002] The slewing module enables the pod to rotate 360°. The connection between the pod's slip-ring rotor wiring and the rotor drum is crucial to ensuring the proper functioning of the pod's slewing module. This involves the precise alignment of electrical signals and power transmission to ensure the module's proper function. The following key points should be considered in the design of the pod's slip-ring rotor wiring connection: Ensure all wiring is accurately connected to the rotor drum and associated electrical control systems; securely mount the wiring on the rotor drum to prevent collisions caused by vibration or movement; and ensure easy inspection and replacement of the wiring for future maintenance and overhaul.

[0003] Existing pod slip-ring rotor wiring connection drums typically include a housing, a rotary interface, cable and pipe fixtures, and a connector locking structure. These components work together to support the rotation of the connected components and transmit the necessary media. Due to the large size of the pod rotation module, existing pod slip-ring rotor wiring connection drums generally have the following problems:

[0004] 1. The entire rotor is integrated, and the slip ring rotor and the nacelle slewing module base are connected by the rotor, spanning different structural layers, making installation difficult. The rotor is large in size and weight, requiring special lifting equipment for installation, resulting in high maintenance costs.

[0005] 2. The slip ring rotor wiring and cable and pipe fixing are all carried out inside the drum. The internal space is limited, the working environment is harsh, and the installation time is long.

[0006] Therefore, it is necessary to design a pod slip-ring rotor connection drum that uses a separate assembly process to effectively solve the existing problem. While considering the hoisting process, the assembly can be carried out in steps. The slip-ring connection can be performed before the upper drum is installed. The lower drum is installed separately, which facilitates the arrangement and fixation of cables and pipes and improves installation efficiency. The side of the upper drum has a large number of ventilation and connection ports, which improves heat dissipation efficiency and facilitates future maintenance and repair. The upper drum adopts a separate assembly, which is easy to install and disassemble, and facilitates the testing and adjustment of the slip-ring rotor connection. The bottom of the drum is octagonal, which facilitates docking and torque transmission. Summary of the Invention

[0007] The purpose of this utility model is to provide a pod slip-ring rotor wiring connection drum, which addresses the difficulties of cable and pipe fixing and internal wiring of the slip-ring rotor. The multi-body split assembly facilitates installation and disassembly, improving installation efficiency. It also systematically organizes the wiring in the pod's rotary module and provides a certain degree of protection for the wiring during operation.

[0008] To achieve the above-mentioned purpose, the technical solution of the utility model is: a pod slip-ring rotor wiring connection rotor, comprising a pod slip-ring rotor wiring connection rotor upper rotor and a pod slip-ring rotor wiring connection rotor lower rotor, the pod slip-ring rotor wiring connection rotor upper rotor is arranged on the pod slip-ring rotor wiring connection rotor lower rotor, the inner surface of the pod slip-ring rotor wiring connection rotor upper rotor is matched with the outer surface of the pod slip-ring rotor wiring connection rotor lower rotor, and is fixed by a bolt group through the bolt holes on the upper flange surface of the lower rotor to form the entire pod slip-ring rotor wiring connection rotor.

[0009] Furthermore, the pod slip ring rotor wiring connection drum upper drum includes the upper drum front, the upper drum rear, the junction box reserved opening, and the ventilation wiring opening. Two ventilation wiring openings are respectively distributed on the three side surfaces of the upper drum front. The middle side surface of the upper drum rear is provided with an opening reserved for the junction box. Two ventilation wiring openings are distributed on each of the left and right side surfaces.

[0010] Furthermore, flange edges are welded on the left and right sides of the front portion of the upper drum and the rear portion of the upper drum respectively, for combining the front portion of the upper drum and the rear portion of the upper drum.

[0011] Furthermore, the pod slip ring rotor connection is connected to the upper rotor, and the upper rotor is connected to the upper rotor front and the upper rotor rear through a bolt group to form a whole.

[0012] Furthermore, the pod slip ring rotor wiring connection rotor lower rotor includes the lower rotor upper flange surface, the fixing frame upper, the fixing frame lower, and the lower rotor lower flange surface. The pod slip ring rotor wiring connection rotor lower rotor is welded on the inner surface of the fixing frame upper and the fixing frame lower, and welded on the outer surface of the lower rotor upper flange surface and the lower rotor lower flange surface.

[0013] Furthermore, the pod slip ring rotor wiring connection drum is divided into a pod slip ring rotor wiring connection drum upper drum and a pod slip ring rotor wiring connection drum lower drum by the upper cover plate of the rotary box body.

[0014] Furthermore, the upper cover plate of the slewing box body is not fixed to the pod slip-ring rotor wiring connection drum, and the upper flange surface of the lower drum supports the upper drum of the pod slip-ring rotor wiring connection drum, and bolts are used to connect the upper drum of the pod slip-ring rotor wiring connection drum and the lower drum of the pod slip-ring rotor wiring connection drum through the bolt holes on the upper flange surface to form the entire pod slip-ring rotor wiring connection drum.

[0015] Furthermore, the pod slip ring rotor wiring connection drum lower drum is fixed to the rotary module connection base through the bolt holes on the lower flange surface of the lower drum with a bolt group, so that the entire pod slip ring rotor wiring connection drum can rotate with the rotary module.

[0016] The beneficial effects of the present invention are mainly reflected in:

[0017] 1. The structure is reasonably designed and is divided into two parts, upper and lower, which reduces the difficulty of overall lifting. The upper drum adopts a separate combination, and the entire bottom surface is octagonal, which is convenient for docking and easy installation and disassembly. The outer part of the lower drum is welded with a flange surface, which makes the upper and lower drums form a whole and fixed on the connection base of the rotary module.

[0018] 2. The upper drum adopts a separate combination to avoid the slip ring rotor wiring and line fixation inside, which improves the installation efficiency. The lower drum is welded with a fixing frame inside to fix the cables and pipes passing through and protect the safety of the internal lines.

[0019] 3. The structure is simple, installation and disassembly are flexible, and the ventilation design is good, which improves the heat dissipation performance of the line and facilitates line inspection and maintenance. The overall octagonal symmetrical design is used to transmit torque, which is convenient for docking and avoids stress concentration.

[0020] The above-mentioned pod slip-ring rotor wiring and rotor drum structure design adopts a multi-body split assembly, which facilitates installation and disassembly, improves the working space for slip-ring rotor wiring and cable and pipe fixing, and improves installation efficiency. The cables and pipes between the pod bottom and the slip ring in the pod slewing module are fixed and organized in an organized manner to provide a certain degree of protection for the lines when the slewing module is operating.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 4 As shown, a pod slip ring rotor wiring connection drum proposed in an embodiment of the present invention includes a pod slip ring rotor wiring connection drum upper drum 1, a pod slip ring rotor wiring connection drum lower drum 2, an upper drum front portion 5, an upper drum rear portion 6, a junction box reserved opening 7, a ventilation wiring opening 8, an upper flange surface 9 of a lower drum, an upper fixing frame 10, a lower fixing frame 11, and a lower flange surface 12 of a lower drum.

[0028] The pod slip ring rotor connection drum is divided into an upper drum 1 for pod slip ring rotor connection drum and a lower drum 2 for pod slip ring rotor connection drum by the upper cover plate 3 of the rotary box.

[0029] The nacelle slip ring rotor connection is connected to the rotor. The upper rotor 1 is composed of an upper rotor front part 5 and an upper rotor rear part 6. The upper rotor front part 5 and the upper rotor rear part 6 are fixed together by a bolt group.

[0030] The left and right side surfaces of the upper drum front portion 5 are welded with flange edges for combining the upper drum front portion 5 and the upper drum rear portion 6 , and each of the three middle side surfaces has two ventilation connection ports 8 .

[0031] Flanges are welded to the left and right sides of the upper rotor rear portion 6 for assembling the upper rotor front portion 5 and the upper rotor rear portion 6. The center side has a reserved opening 7 for the junction box, and each of the remaining two sides has two ventilation connection openings 8. This facilitates assembly between the upper and lower rotors. Multiple ventilation connection openings improve the heat dissipation efficiency of the circuits, facilitating inspection and maintenance of the circuits. When wiring the slip-ring rotor, wiring can be performed first, followed by assembly of the nacelle slip-ring rotor connection to the upper rotor, improving the wiring working environment and increasing installation efficiency. The entire rotor bottom surface is octagonally symmetrical, facilitating adjustments during wiring, reducing the difficulty of docking the upper rotor front and rear, and facilitating torque transmission between the upper and lower rotors. The symmetrical structure also prevents stress concentration on the upper rotor when it is driven by the lower rotor.

[0032] The pod slip-ring rotor connection drum lower rotor 2 includes: an upper flange surface 9, an upper fixing frame 10, a lower fixing frame 11, and a lower flange surface 12 of the lower rotor. The upper fixing frame 10 and the lower fixing frame 11 are welded to the inside of the pod slip-ring rotor connection drum lower rotor 2, while the upper flange surface 9 and the lower flange surface 12 of the lower rotor are welded to the outside of the pod slip-ring rotor connection drum lower rotor 2.

[0033] The upper rotor 1 of the pod slip ring rotor wiring connection drum is on the lower rotor 2 of the pod slip ring rotor wiring connection drum. The inner surface of the upper rotor 1 of the pod slip ring rotor wiring connection drum matches the outer surface of the lower rotor 2 of the pod slip ring rotor wiring connection drum, and is fixed with a bolt group through the bolt holes on the flange surface 9 of the lower rotor to form the entire pod slip ring rotor wiring connection drum. Figure 1 As shown in the figure, the slewing housing upper cover plate 3 divides the entire pod slip-ring rotor connection drum into an upper drum and a lower drum, but is not fixed to the pod slip-ring rotor connection drum upper drum 1 and the pod slip-ring rotor connection drum lower drum 2. The pod slip-ring rotor connection drum lower drum 2 is fixed to the slewing module connection base 4 through the bolt holes in the lower flange surface 12 of the lower drum.

[0034] When the pod rotates, the slewing module connection base 4 drives the pod slip ring rotor wiring connection drum lower drum 2 to rotate, and the junction box installed on the pod slip ring rotor wiring connection drum upper drum 1 and the cables inside the drum rotate with the entire pod slip ring rotor wiring connection drum.
