Description

Technical Field

[0001] This utility model relates to the field of cable protection devices, and in particular to a protection device for the collector lines of onshore wind farms. Background Technology

[0002] Wind power projects stand out in the context of clean energy development. These projects typically need to be built in remote areas with abundant wind resources and sparse populations to make full use of local wind resources. However, due to the remoteness of the construction area, it is extremely inconvenient to maintain the lines in the wind farm. Therefore, it is necessary to protect the cable lines in the wind farm to increase the service life of the circuit and reduce the number of circuit maintenance. In particular, the ground-laid collection lines are easily affected by external environmental factors (such as rain) and transportation vehicles, which greatly affects their operation and maintenance efficiency and service life.

[0003] In existing technologies, the main protective measures for ground lines in wind farms include using conduits and outer sheaths to protect the lines. However, when the line length is long, it is necessary to connect the conduits or outer sheaths. During the connection, improper operation by the staff or the process error of the equipment itself may cause gaps to appear between the conduits, allowing rainwater or other corrosive liquids to seep in through the gaps and cause corrosion damage to the circuit cables, making it difficult to achieve the best protection effect. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the circuit cables being easily corroded and damaged due to the loose connection of the outer sheath, and to propose a protection device for the collector lines of onshore wind farms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protection device for the collector lines of an onshore wind farm includes several cable boxes, with every two adjacent cable boxes connected together. Each cable box includes:

[0007] The box body is trapezoidal in shape. Side bottom plates are provided on both sides of the box body. Several mounting holes are provided on the side bottom plates. A placement groove is also provided inside the box body. A cover plate is slidably provided on the placement groove.

[0008] Two connecting mechanisms are provided on the box body, and two adjacent cable boxes are connected by the connecting mechanisms.

[0009] A seepage prevention mechanism is installed on the box body and is used to cover the connection gap after the two cable boxes are connected.

[0010] Furthermore, a number of rubber pads are provided on the bottom end of the box body. The rubber pads are in the shape of annular protrusions and are evenly distributed along the length direction of the box body.

[0011] Furthermore, several partitions are evenly arranged inside the placement slot, and the partitions divide the placement slot into several cable slots.

[0012] Furthermore, the connecting mechanism includes:

[0013] A connector is provided at one end of the housing, and a threaded hole is provided in the connector from top to bottom through its center;

[0014] A connector hole is provided on the box body at one end away from the connector head. The connector hole is adapted to the connector head. A through hole is provided in the connector hole, which is adapted to the screw hole.

[0015] A fastener, wherein the fastener is movably disposed within the through hole, and the fastener is a screw.

[0016] Furthermore, the end of the connector furthest from the housing is chamfered.

[0017] Furthermore, the seepage prevention mechanism includes:

[0018] A sealing plate, wherein the sealing plate is disposed at one end of the box body, and the sealing plate is made of rubber material;

[0019] A sealing groove is provided on the box body at one end away from the sealing plate, and the sealing groove is adapted to the sealing plate;

[0020] A shield, which is a strip-shaped structure adapted to the cable box, is located at the top of the box body, and half of the shield is fixed to the box body, while the other half is coated with a rubber layer.

[0021] The beneficial effects of this utility model are as follows:

[0022] This application sets up several cable boxes, each with a placement slot inside. After placing the circuit cables in the placement slot, a connecting mechanism secures adjacent cable boxes together. Under the action of the anti-seepage mechanism, rainwater is effectively prevented from entering the placement slot. This solves the technical problem that rainwater can seep through the connection gaps and come into contact with the circuit cables, causing corrosion and damage. It achieves multiple protections for the circuit cables and extends their service life. Attached Figure Description

[0034] Reference Figures 1 to 3 As shown, an onshore wind farm power collection line protection device is mainly used in practical applications to protect ground power cables in onshore wind farms. It includes several cable boxes, with each pair of adjacent cable boxes being fixedly connected. The power cables are placed inside the cable boxes, that is, in each pair of adjacent cable boxes, the head of one is fixedly assembled with the tail of the other, thereby protecting the ground power cables through the cable boxes.

[0035] For ease of description, this section uses one cable box as an example. The cable box includes a box body 1, and two connecting mechanisms 2 and a seepage prevention mechanism 3 disposed on the box body 1. Specifically, the box body 1 has an overall trapezoidal structure. The reason for this is that the trapezoidal structure, which is narrower at the top and wider at the bottom, can effectively prevent cable compression and deformation due to local overload, and disperse external pressure such as vehicle crushing along the inclined surface to a larger contact area, preventing damage to the box body 1 due to excessive force. The inclined surfaces on both sides of the box body 1 extend in a direction perpendicular to the width of the box body 1, forming plate-like protrusions. These plate-like protrusions are side bottom plates 11, and the side bottom plates 11 have several mounting holes 12. When it is necessary to fix the box body 1 to the ground, screws or other anchors are inserted into the ground through the mounting holes 12 and tightened to fix the box body 1 to the ground, preventing the box body 1 from moving freely after installation.

[0036] In some preferred embodiments, a plurality of rubber pads (not shown in the figure) are also provided on the bottom end of the box body 1. The rubber pads are in the shape of annular protrusions and are evenly distributed along the length of the box body 1. On the one hand, the box body 1 can provide shock absorption through the rubber pads. On the other hand, in places where it is inconvenient to fix the box body 1, such as uneven ground, the rubber pads can increase the friction between the box body 1 and the ground, further reducing the possibility of the box body 1 moving on the ground.

[0037] In some preferred embodiments, the inclined surface of the box body 1 is also provided with anti-slip texture to increase the friction between the tire and the box body 1 when the vehicle passes by, and to prevent the vehicle tire from slipping.

[0038] In this embodiment, the top of the box 1 is recessed inward along its length to form a groove-like structure. This groove-like structure is a placement slot, with an unobstructed opening at its top. Both ends of the placement slot are through openings, meaning they extend through the box 1 to allow electrical cables to pass through. Several partitions are evenly arranged within the placement slot, dividing it into several cable slots 13 of equal size for placing different types or models of electrical cables. This facilitates quick selection of different types or models of electrical cables during inspection or maintenance, improving work efficiency. Two symmetrical sliding grooves are also formed at the opening of the placement slot, extending along the length of the box 1. A cover plate 14 is also provided at the opening of the placement slot. The cover plate 14 is slidably connected to the two sliding grooves. That is, the cover plate 14 can slide in the sliding grooves by cooperating with the sliding grooves, thereby opening or closing the top space of the placement slot. For example, when it is necessary to inspect and maintain one section of the circuit cable, the cover plate 14 can be slid along the sliding grooves to expose the placement slot. At this time, the staff can maintain the circuit cable in the placement slot.

[0039] In this embodiment, two connecting mechanisms 2 are disposed on both sides of the same end of the housing 1, and the two connecting mechanisms 2 are symmetrically arranged about the central axis of the housing 1. Two adjacent cable boxes 1 are connected by the connecting mechanisms 2. For ease of description, the connecting mechanism 2 is described here as a single connecting mechanism 2. The connecting mechanism 2 includes a connector 21, a socket 22 adapted to the connector 21, and a fixing member 23. The connector 21 is disposed at one end of the housing 1. The connector 21 may be, but is not limited to, a square shape, or a circular or other protruding columnar structure, and a threaded hole penetrating its center is formed from top to bottom inside the connector 21. The connection hole 22 is located on the end of the housing 1 away from the connector 21, and the connection hole 22 is adapted to the connector 21, that is, it is located on the same axis as the connector 21. The connection hole 22 is a groove-shaped structure adapted to the connector 21. When two adjacent cable boxes 1 need to be connected, the connector 21 on one cable box 1 is inserted into the connection hole 22 on the other cable box 1 to connect the two adjacent cable boxes 1. The connection hole 22 also has a through hole vertically arranged through the housing 1, and the through hole is adapted to the screw hole, that is, after the connector 21 is inserted into the connection hole 22, the diameter of the screw hole is adapted to the diameter of the through hole. The fixing member 23 is movably disposed in the through hole. Preferably, the fixing member 23 is a screw. After the connector 21 is inserted into the connection hole 22, the screw is inserted into the through hole and threadedly connected to the screw hole of the connector 21, thereby fixing the connector 21 in the connection hole 22, thereby preventing the two cable boxes 1 from separating after connection and making the connection between the two cable boxes 1 more stable.

[0040] In some preferred embodiments, the end of the connector 21 away from the housing 1 is chamfered to guide the connector 21 when it is inserted into the hole 22, making it easier to align and insert the connector 21 into the hole 22, thus reducing assembly time and difficulty.

[0041] In this embodiment, since gaps may form at the connection point after two adjacent cable boxes 1 are connected, rainwater and other substances may enter the cable box 1 through the gaps, causing corrosion and damage to the electrical cables. The anti-seepage mechanism 3 is disposed on the box body 1 at one end of the connector 21. After the two cable boxes 1 are connected, it is used to cover the connection gap to reduce the possibility of rainwater and other substances entering the cable box 1 through the gap at the connection point. Specifically, the anti-seepage mechanism 3 includes a sealing plate 31, a sealing groove 32 adapted to the sealing plate 31, and a shielding plate 33 located on the box body 1. The sealing plate 31 is disposed at one end of the box body 1, and the sealing plate 31 is adapted to the through opening on the box body 1 at one end of the connector 21. That is, the sealing plate 31 has several openings adapted to the placement groove, so that the electrical cables can enter the adjacent cable box 1 through the openings. The sealing groove 32 is located on the end of the box 1 away from the sealing plate 31, and the sealing groove 32 is adapted to the sealing plate 31. That is, both the sealing groove 32 and the sealing plate 31 are provided with openings adapted to the placement groove. When two adjacent cable boxes 1 are connected, the through openings in the two adjacent cable boxes 1 are sealed by snapping the sealing plate 31 and the sealing groove 32 together, thereby preventing rainwater from entering the placement groove. Preferably, the sealing plate 31 is made of rubber material. The reason for this is that rubber material, due to its high elasticity and plasticity, can effectively fill the gaps generated when the sealing plate 31 and the sealing groove 32 are snapped together, thereby achieving a tight sealing effect. The shielding plate 33 is a strip-shaped structure adapted to the cable box 1. It is located at the top of the box body 1, and half of the bottom end of the shielding plate 33 is fixed to the box body 1 by means of sealing connection such as adhesive bonding. The other half is coated with a rubber layer. When two adjacent cable boxes 1 are connected, the rubber layer covers the gap at the connection of the two cable boxes 1, further reducing the possibility of rainwater seeping into the placement groove through the gap.

[0042] In this embodiment, by setting up a plurality of cable boxes 1, and setting a placement groove in the box body 1 of each cable box 1, after the circuit cable is placed in the placement groove, the two adjacent cable boxes 1 are fixedly connected by the connecting mechanism 2. Under the action of the anti-seepage mechanism 3, rainwater is effectively prevented from entering the placement groove, which solves the technical problem that rainwater will seep through the connection gap and come into contact with the circuit cable, causing corrosion and damage to the circuit cable. This achieves multiple protections for the circuit cable and extends its service life.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
