Description

Technical Field

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

[0002] The slewing module can make the pod body slew 360°, and the connection of the pod slip ring rotor to the drum is an important part to ensure the normal operation of the pod slewing module. The connection of the pod slip ring rotor to the drum involves the precise docking of electrical signals and power transmission to ensure the normal operation of the slewing module. In the design of the pod slip ring rotor connection to the drum, the following key points should generally be considered: ensure that all lines are accurately connected to the drum and related electrical control systems; the wiring should be firmly installed on the drum to prevent line collision caused by vibration or movement; consider future maintenance and overhaul, so that the wiring is easy to check and replace.

[0003] The existing pod slip ring rotor wiring connection drum generally includes a housing, a rotation interface, a cable and pipe fixture, and a connector locking structure, etc. These components work together to support the rotation of the connection parts and transmit the necessary media. Due to the large size of the pod rotation module, the existing pod slip ring rotor wiring connection drum generally has the following problems:

[0004] 1. The entire rotor is integrated. The slip ring rotor and the base of the nacelle slewing module are connected by the rotor, spanning different structural layers, which makes installation difficult. The rotor is large in size and weight, requiring special lifting equipment for installation, and has 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 wiring connection drum, which adopts separate assembly molding to effectively solve the existing problems. While considering the hoisting, it can be assembled in steps. The slip ring wiring can be carried out before the upper drum is installed. The lower drum is installed separately, which is convenient for the arrangement and fixation of cables and pipes and improves the installation efficiency. There are more ventilation and wiring ports on the side of the upper drum, which improves the heat dissipation efficiency and facilitates future maintenance and overhaul. The upper drum adopts a separate combination, which is easy to install and disassemble, and convenient for testing and adjustment of the slip ring rotor wiring. The bottom of the drum is octagonal, which is convenient for docking and torque transmission. Summary of the invention

[0007] The purpose of the present invention is to propose a pod slip ring rotor wiring connection drum, which improves the situation of difficult cable and pipeline fixing and internal wiring of slip ring rotor. It adopts a multi-body separation combination, which is convenient for installation and disassembly, improves installation efficiency, classifies and organizes the lines in the pod rotary module in an orderly manner, and can provide certain protection for the lines when the rotary module is working.

[0008] To achieve the above-mentioned purpose, the technical solution of the present invention 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 pod slip-ring rotor wiring connection rotor upper rotor inner surface is matched with the pod slip-ring rotor wiring connection rotor lower rotor outer surface, and is fixed by a bolt group through the bolt holes on the 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 an upper drum front, an upper drum rear, a junction box reserved opening, and a ventilation wiring opening. Two ventilation wiring openings are respectively distributed on the three side surfaces of the upper drum front, and an opening for the junction box reserved opening is provided on the middle side surface of the upper drum rear, and 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 part of the upper drum and the rear part of the upper drum respectively, which are used for the combination of the front part of the upper drum and the rear part of the upper drum.

[0011] Furthermore, the pod slip ring rotor connection connection drum upper drum is formed into a whole by connecting the upper drum front part and the upper drum rear part through a bolt group.

[0012] Furthermore, the pod slip ring rotor wiring connection rotor lower drum comprises a lower drum upper flange surface, a fixing frame upper, a fixing frame lower, and a lower drum lower flange surface; the pod slip ring rotor wiring connection rotor lower drum lower drum is welded on the inner surface of the fixing frame upper and the fixing frame lower, and on the outer surface the lower drum upper flange surface and the lower drum lower flange surface are welded.

[0013] Furthermore, the pod slip ring rotor connection drum is divided into a pod slip ring rotor connection drum upper drum and a pod slip ring rotor connection drum lower drum by an upper cover plate of a 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, 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 by 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 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 an octagon, 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, the installation and disassembly are flexible, and the ventilation design is good, which improves the heat dissipation performance of the line and facilitates the line inspection and maintenance. The overall octagonal symmetrical design is used to transmit torque, which is convenient for docking and avoids stress concentration.

The cables and pipelines between the pod bottom and the slip ring in the pod rotary module are fixed and sorted in an orderly manner to provide certain protection for the lines when the rotary module is working.

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

[0029] The upper rotor 1 of the nacelle slip ring rotor connection connection rotor is composed of an upper rotor front part 5 and an upper rotor rear part 6, and 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 sides of the upper drum front part 5 are welded with flange edges for combining the upper drum front part 5 and the upper drum rear part 6, and each of the three middle sides has two ventilation connection ports 8.

[0031] The left and right sides of the upper drum rear part 6 are welded with flange edges for the combination of the upper drum front part 5 and the upper drum rear part 6. The middle side has a junction box reserved opening 7, and each of the remaining two sides has two ventilation connection openings 8. It is convenient to assemble between the upper drum and the lower drum. Multiple ventilation connection openings improve the heat dissipation efficiency of the line and facilitate the inspection and maintenance of the line. When wiring the slip ring rotor, the wiring work can be carried out first, and then the nacelle slip ring rotor wiring connection drum upper drum assembly can be carried out, which improves the working environment during wiring and improves the installation efficiency. The bottom surface of the entire drum is octagonally symmetrical, which is convenient for adjustment during wiring, reduces the difficulty of docking the front and rear of the upper drum, and is also conducive to the torque transmission between the upper drum and the lower 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 by 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, such as Figure 1 As shown. The upper cover plate 3 of the slewing box body divides the entire pod slip ring rotor wiring connection drum into an upper drum and a lower drum, but is not fixed to the pod slip ring rotor wiring connection drum upper drum 1 and the pod slip ring rotor wiring connection drum lower drum 2. The pod slip ring rotor wiring connection drum lower drum 2 is fixed to the slewing module connection base 4 through the bolt holes on the lower flange surface 12 of the lower drum.

[0034] When the pod rotates, the rotating 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.
