Description

Technical Field

[0001] This utility model relates to the field of installation accessories for wind turbine nacelle control cabinets, specifically to a terminal layer assembly structure. Background Technology

[0002] like Figure 5 and Figure 6 As shown, the terminal block assembly structure is used to assemble the wiring terminals and cable trays to the bottom of the wind turbine nacelle control cabinet. These wiring terminals are used to connect cables inside and outside the control cabinet. Because the assembly structure is located at the bottom of the control cabinet, the wiring positions are not visible when wiring from the bottom of the terminals, making wiring very difficult. Furthermore, since the holes for fixing the cable tray layer are located below the cable trays, holes need to be drilled in the cable trays to secure the layer, increasing manufacturing costs. The screws used for fixing also pose a risk of cable wear.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0004] The purpose of this utility model is to provide a terminal layer assembly structure to overcome the above-mentioned shortcomings and deficiencies of the prior art.

[0005] A terminal shelf assembly structure includes: a shelf column, a cable tray shelf, a terminal shelf, a wire binding bracket, and a terminal guide rail. The shelf column is connected to a wind turbine nacelle control cabinet. The shelf column is also connected to the cable tray shelf and the terminal shelf. A cable tray is fixed on the cable tray shelf. The terminal guide rail is connected to the terminal shelf. The wire binding bracket is connected to the shelf column. A terminal block is fixed on the terminal guide rail.

[0006] The cable tray layer includes: a cable tray layer body, a front flange of the cable tray layer, a rear flange of the cable tray layer, and a cable tray layer fixing component. The front end of the cable tray layer body is connected to the front flange of the cable tray layer, the rear end of the cable tray layer body is connected to the rear flange of the cable tray layer and the cable tray layer fixing component, the front flange of the cable tray layer is connected to the tray column, and the cable tray layer body is connected to the tray column through the cable tray layer fixing component.

[0007] The terminal layer plate includes: a terminal layer connecting edge, a terminal layer plate body, and a terminal layer flange. One end of the terminal layer plate body is connected to the terminal layer connecting edge, and the connection angle between the terminal layer plate body and the terminal layer connecting edge is 20°. The other end of the terminal layer plate body is connected to the terminal layer flange. The terminal layer connecting edge is connected to the top of the plate column through a connecting hole, and the terminal layer flange is connected to the column body of the plate column through a connecting hole.

[0008] The beneficial effects of this utility model are:

[0009] Compared with traditional technology, this utility model divides the traditional integrated shelf into a cable tray shelf and a terminal shelf. The cable tray shelf is equipped with independent connectors and connection holes to avoid the risk of cable wear caused by protruding screws.

[0022] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Example 1

[0024] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a diagram showing the usage state of this utility model. Figure 3This is a schematic diagram of the structure of the cable tray layer. Figure 4 This is a schematic diagram of the terminal block structure. Figure 5 This is a schematic diagram of the structure of traditional technology. Figure 6 This is a schematic diagram of the installation of a traditional terminal block. Figure 7 This is a schematic diagram of the installation of the terminal layer plate of this utility model.

[0025] like Figure 1 and Figure 2 As shown, a terminal shelf assembly structure includes: a shelf column 100, a wire trough shelf 200, a terminal shelf 300, a wire binding bracket 400, and a terminal guide rail 500. The shelf column 100 is connected to the wind turbine nacelle control cabinet 1. The shelf column 100 is connected to the wire trough shelf 200 and the terminal shelf 300. A wire trough 2 is fixed on the wire trough shelf 200. The terminal guide rail 500 is connected to the terminal shelf 300. The wire binding bracket 400 is connected to the shelf column 100. A terminal block 3 is fixed on the terminal guide rail 500.

[0026] like Figure 3 As shown, the cable tray shelf 200 includes: cable tray shelf body 210, cable tray front flange 220, cable tray rear flange 230 and cable tray fixing member 240. The front end of the cable tray shelf body 210 is connected to the cable tray front flange 220, the rear end of the cable tray shelf body 210 is connected to the cable tray rear flange 230 and the cable tray fixing member 240, the cable tray front flange 220 is connected to the shelf column 100, and the cable tray shelf body 210 is connected to the shelf column 100 through the cable tray fixing member 240.

[0027] like Figure 4 As shown, the terminal layer plate 300 includes: a terminal layer connecting edge 310, a terminal layer plate body 320, and a terminal layer flange 330. One end of the terminal layer plate body 320 is connected to the terminal layer connecting edge 310, and the connection angle between the terminal layer plate body 320 and the terminal layer connecting edge 310 is 20°. The other end of the terminal layer plate body 320 is connected to the terminal layer flange 330. The terminal layer connecting edge 310 is connected to the top of the plate column 100 through a connecting hole, and the terminal layer flange 330 is connected to the column body of the plate column 100 through a connecting hole.

[0028] The innovation of this utility model lies in the fact that the traditional integrated layer plate is first cut into wire groove layer plate 200 and terminal layer plate 300. The purpose of doing so is that the wire groove layer plate 200 and terminal layer plate 300, which correspond to the original positions, need to be improved according to the problem. Therefore, in order to meet the basic requirements of improvement, they are made into independent structures.

[0029] Secondly, the structure of the cable tray layer 200 solves the defects of the original layer in this position. In traditional technology, the holes for fixing the cable tray layer were located below the cable tray, requiring drilling through the cable tray, which increased the manufacturing process and cost. Furthermore, the fixing screws protruded inside the cable tray, causing long-term friction with the cables inside, leading to cable wear and functional failure. Therefore, the cable tray layer 210 of this invention does not require drilling; instead, it has a pre-installed cable tray layer fixing component 240 with holes. These operations can be completed uniformly during the processing of the cable tray layer 200, eliminating the need for on-site operation and avoiding quality problems caused by drilling. The front flange 220 and rear flange 230 of the cable tray layer ensure the installation stability of the already independent cable tray layer 200.

[0030] like Figure 7 As shown, the final improvement is to the terminal shelf 300. Traditionally, the terminal shelf is horizontally positioned, attached to the shelf support column. Since the terminal shelf assembly structure is located at the bottom of the wind turbine nacelle control cabinet 1, wiring personnel must perform wiring in an ergonomically unfriendly position, making the wiring work very difficult. The independent terminal shelf 300 has the terminal shelf body 320 at a 20° angle to the shelf support column 100, allowing the wiring viewpoint of the terminal shelf body 320 to face upwards. This allows wiring personnel to perform wiring in an ergonomically comfortable position, reducing wiring difficulty, error rate, and wiring time.

[0031] Compared with traditional technology, this utility model divides the traditional integrated shelf into a cable tray shelf and a terminal shelf. The cable tray shelf is equipped with independent connectors and connection holes to avoid the risk of cable wear caused by protruding screws. The connection angle between the shelf column and the terminal shelf is 20°, allowing wiring personnel to connect the wires in an ergonomic manner, reducing wiring difficulty, wiring error rate and wiring time.

[0032] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
