Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a guide device for laying underground cables in wind farms. Background Technology

[0002] A wind farm, also known as a wind power plant or wind power station, is a facility that uses wind turbines to convert wind energy into electrical energy. It typically consists of multiple wind turbines installed at specific locations to maximize the capture of wind energy. The cables used in wind farms are mainly used to transmit the electrical energy generated by the wind turbines to the power grid.

[0003] When cables are laid in underground cable wells, a guiding device is needed to guide the cable transport. For example, Chinese Patent Publication No. CN117638732B discloses a cable laying guiding device, including a fixed base, a bracket fixedly connected to the top of the fixed base, a connecting wheel rotatably connected inside the bracket, a connecting seat rotatably connected to one end of the fixed base, and a connecting frame fixedly connected to the top of both the connecting seat and the fixed base. This invention guides the cable transport through pulleys on the surface of the connecting seat. The rotational effect between the connecting seat and the fixed base allows for adaptive rotation of the cable during its entry process, and the guide wheel further guides and transports the cable. This prevents the cable from detaching from the device due to twisting during oscillation. The rotational effect of the ball bearings prevents friction between the cable sheath and the cable well opening as the cable is transported through the connecting wheel into the cable well, preventing cable surface wear and potential safety hazards such as leakage.

[0004] In actual operation, the cable is transported by guide wheels on both sides. However, the guide wheels cannot be adjusted to reverse direction with the top frame and the connecting frame. This means that when the cable needs to be transported in a turning position, it may rub against the connecting frame, resulting in damage to the outer sheath. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the guide wheels cannot be adjusted for reversal, and to propose a guiding device for laying underground cables in wind farms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a wind farm underground cable laying guide device, including a frame, with at least one row of guide mechanisms evenly distributed inside the frame, each guide mechanism including a pair of brackets, with guide wheels located on the upper and lower sides between the pair of brackets, and a tensioning structure between the brackets and one of the guide wheels, the guide wheels on both sides pressing against the cable through the tensioning structure;

[0008] A steering mechanism is provided between the frame and the bracket near the end, the steering mechanism being used to adjust the guiding direction of the guide wheel pair cable.

[0009] Furthermore, the guiding mechanism also includes fasteners, and a pair of brackets are provided with connecting parts on the upper and lower sides. The fasteners pass through the connecting parts on both sides and are rotatably connected to the guide wheels on the periphery. The pair of brackets are fixedly connected by the fasteners.

[0010] Furthermore, the tensioning structure includes a slider, wherein two of the connecting parts on one side are provided with straight grooves, and the straight grooves on both sides extend toward the midpoint on opposite sides to form a stop. The slider is slidably connected in the straight grooves by a compression spring, and the two sides of the slider also abut against the stop and the guide wheel respectively.

[0011] The fastener is slidably connected to the straight groove at both ends, and the slider is also provided at both ends.

[0012] Furthermore, the steering mechanism includes a connecting rod, which is fixedly connected to the top of the bracket and also slidably connected within the top guide groove of the frame.

[0013] Furthermore, it also includes a positioning disk, which is fixedly connected to the top of the connecting rod. Several pairs of positioning holes are distributed around the periphery of the positioning disk. The top of the frame is provided with a pair of protruding structures at both ends of the guide groove, and the pair of protruding structures engage with the positioning holes.

[0014] Furthermore, a spring is sleeved around the top periphery of the connecting rod, and a nut is threadedly connected thereto. The two ends of the spring abut against the positioning plate and the nut, respectively.

[0015] The present invention provides a cable laying guide device for wind farms, which has the following advantages: The device allows for the fixing and disassembly of a pair of brackets using locking bolts. On one hand, the brackets support the tensioning structure, enabling the guide wheels on both sides to adapt to cables of different diameters within a certain range under the action of the tensioning components, thereby achieving the function of guiding the cables. On the other hand, disassembling the pair of brackets allows for the disassembly and replacement of the tensioning structure. Furthermore, the guiding direction of the guide wheels can be adjusted through a reversing mechanism, allowing the cable to be transported in a turning manner, avoiding damage caused by the outer sheath colliding with the frame during cable transport.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A wind farm underground cable laying guide device includes a frame 1, and at least one row of guide mechanisms 2 are evenly distributed inside the frame 1. The guide mechanism 2 includes a pair of brackets 21, and guide wheels 22 are provided on the upper and lower sides between the pair of brackets 21. A tensioning structure 3 is provided between the brackets 21 and one of the guide wheels 22, and the guide wheels 22 on both sides abut against the cable through the tensioning structure 3.

[0023] A steering mechanism 4 is provided between the frame 1 and the bracket 21 near the end, and the steering mechanism 4 is used to adjust the guiding direction of the guide wheel 22 on the cable.

[0024] It should be added that several connecting legs are fixedly connected to the bottom of the frame 1. The connecting legs are connected to the underground cable well, so that the guiding mechanism 2 can stably guide the cable. The cable is transported along the guide wheel 22 by connecting one end to the traction device and under the action of the guiding mechanism 2.

[0025] Furthermore, the guide mechanism 2 also includes a fastener 26. A pair of brackets 21 are provided with connecting parts 23 on the upper and lower sides. The fastener 26 passes through the connecting parts 23 on both sides and is rotatably connected to the guide wheel 22 on the periphery. The pair of brackets 21 are fixedly connected by the fastener 26.

[0026] In this embodiment, the fastener 26 includes a locking bolt and a nut. The locking bolt is rotatably connected to a guide wheel 22. The locking bolt passes through a pair of brackets 21 and is threadedly connected to a nut to fix the pair of brackets 21. The pair of brackets 21 are triangular or rectangular in structure.

[0027] Furthermore, the tensioning structure 3 includes a slider 31, wherein the two connecting parts 23 on one side are provided with straight grooves 24, and the straight grooves 24 on both sides extend towards the midpoint on opposite sides to form a stop part 25. The slider 31 is slidably connected in the straight groove 24 by a compression spring 32, and the two sides of the slider 31 also abut against the stop part 25 and the guide wheel 22 respectively.

[0028] The fastener 26 is slidably connected to the straight groove 24 at both ends, and the slider 31 is also provided at both ends.

[0029] In actual operation, the fastener 26 is slidably connected in the straight grooves 24 on both sides. When the cable touches the guide wheel 22, the fastener 26, together with the slider 31 and the compression spring 32, drives the guide wheel 22 to slide upward. Utilizing the elastic effect of the compression spring 32, the guide wheels 22 on both sides can effectively tighten and guide cables of different diameters within a certain range.

[0030] More specifically, the steering mechanism 4 includes a connecting rod 41, which is fixedly connected to the top of the bracket 21 and slidably connected within the top guide groove 11 of the frame 1.

[0031] In general, it also includes a positioning disk 42, which is fixedly connected to the top of the connecting rod 41. Several pairs of positioning holes 43 are distributed around the periphery of the positioning disk 42. The top of the frame 1 is provided with a pair of protruding structures 44 at both ends of the guide groove 11. The pair of protruding structures 44 engage with the positioning holes 43. In this embodiment, the protruding structures 44 are preferably set as positioning glass beads embedded in the upper end of the frame 1. The circumferential position of the positioning disk 42 is completed by the engagement of the telescopic end of the positioning glass beads with the positioning holes 43. Of course, in other embodiments, it can also be set as an elastic protrusion, such as a plastic protrusion.

[0032] Finally, a spring 45 is sleeved on the top periphery of the connecting rod 41, and a nut 46 is threadedly connected thereto. The two ends of the spring 45 are respectively pressed against the positioning plate 42 and the nut 46.

[0033] It should be noted that several guide mechanisms 2 are arranged side by side. In order to prevent the guide wheel 22 on the outermost side from deviating from the guide position with the guide mechanism 2 on the side after it changes direction, the connecting rod 41 can be driven to drive the bracket 21 to slide along the guide groove 11.

[0034] Specifically, the positioning disk 42 has several pairs of positioning holes 43 distributed around its circumference. When the positioning holes 43 at different angles engage with the protruding structure 44, the reversing direction of the guide wheel 22 can be adjusted in multiple positions.

[0035] When the nut 46 is tightened, it presses the positioning plate 42 against the spring 45. When the positioning plate 42 engages with the protruding structure 44 through the positioning hole 43, it fixes the connecting rod 41 and the bracket 21 to prevent them from deviating.

[0036] Working method: During operation, the frame 1 is fixed to the cable well through the connecting legs at the bottom. The cable is passed between the guide wheels 22 on the upper and lower sides. After one of the guide wheels 22 comes into contact with the cable, it drives the fastener 26 and the slider 31 to slide upward. The guide wheel 22 will also cooperate with the other guide wheel 22 under the action of the compression spring 32 to press and transport the cable.

[0037] When the cable needs to be transported in a bend, the nut 46 is turned to unlock the spring 45. After the positioning plate 42 is slid upward to disengage the protruding structure 44 from the positioning hole 43, the connecting rod 41 can be slid to drive the bracket 21 to move. Furthermore, the guide wheel 22 can be adjusted in multiple positions by engaging the positioning hole 43 with the protruding structure 44 at different angles.

[0038] Finally, tighten the nut 46 so that the nut 46 presses against the positioning plate 42 through the spring 45, thereby fixing the guide wheel 22 and guiding its direction.

[0039] 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.
