Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a deep trench direct burial protective device for wind farm collector cables. Background Technology

[0002] To prevent damage to cables from external mechanical forces, such as squeezing or puncturing caused by construction activities, vehicle traffic, agricultural work, or ditch digging in wind farms, protective devices are generally made of sturdy materials, such as high-strength metals or reinforced plastics.

[0003] The existing technology has the following problems: The existing equipment does not have a buffer tension mechanism during use. In the cable laying area, there may be various ground activities, such as vehicle traffic and construction. The vibrations and pressures generated by these activities are transmitted underground. Without a buffer tension mechanism, the equipment will directly bear these external forces, causing damage or deformation to the internal structure. In addition, the existing equipment cannot be spliced. Since the protective device cannot be spliced, a larger integrated protective device is required during transportation. This not only places higher demands on the size and load-bearing capacity of the transport vehicle, but also makes the handling process more difficult. Utility Model Content

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.

[0016] like Figure 1 As shown, this utility model provides a deep trench direct burial protection device for wind farm collector cables, including a fixed sleeve 1, a movable plate 2 fixedly connected to the rear side of the fixed sleeve 1, a movable sleeve 3 provided behind the fixed sleeve 1, the outer wall of the movable plate 2 slidably connected to the movable sleeve 3, two snap-fit ​​blocks 4 fixedly connected to the front side of the fixed sleeve 1, two insertion ports 14 opened on the rear side of the movable sleeve 3, the outer wall of the snap-fit ​​blocks 4 movably connected to the insertion ports 14, and slots 15 are opened on both the upper and lower sides of the inner surface of the insertion ports 14. This deep trench direct burial protection device for wind farm collector cables is mainly composed of a fixed sleeve 1 and a movable sleeve 3. The movable plate 2 connected to the rear side of the fixed sleeve 1 is slidably connected to the movable sleeve 3. This structure provides a movable basis for buffering tension. At the same time, the snap-fit ​​blocks 4 on the front side of the fixed sleeve 1 are movably connected to the insertion ports 14 on the rear side of the movable sleeve 3, and the slots 15 on both the upper and lower sides of the inner surface of the insertion ports 14 provide a key structure for splicing the protection device.

[0017] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, two rotating plates 7 are rotatably connected to the rear side of the movable plate 2, and a movable block 8 is rotatably connected to the other end of the rotating plate 7. Two support plates 9 are fixedly connected to the inner surface of the movable sleeve 3, and a fixed rod 10 is fixedly connected to the opposite face of the two support plates 9. The outer wall of the fixed rod 10 is slidably connected to the movable block 8. A damping shock absorber 11 is fixedly connected to the opposite face of the two movable blocks 8. Two limiting rods 5 are fixedly connected to the rear side of the inner surface of the movable sleeve 3. The outer wall of the limiting rod 5 is slidably connected to the movable plate 2. A spring 6 is sleeved on the outer wall of the limiting rod 5. One end of the spring 6 is fixedly connected to the movable sleeve 3, and the other end of the spring 6 is fixedly connected to the movable plate 2. A limiting block 12 is fixedly connected to the front end of the limiting rod 5. Two limiting grooves 13 are opened on the inner surface of the movable plate 2. The outer wall of the limiting block 12 is... Slidingly connected to the limiting groove 13, when the protective device is subjected to tensile or compressive forces caused by external ground movement, soil deformation, etc., the movable plate 2 will displace relative to the movable sleeve 3. The rotating plate 7 rotatably connected to the rear side of the movable plate 2 will drive the movable block 8 to slide on the fixed rod 10. The damping shock absorber 11 between the two movable blocks 8 can absorb some vibration energy and play a buffering role. At the same time, the limiting rod 5 on the rear side of the inner surface of the movable sleeve 3 slides in the limiting groove 13 on the inner surface of the movable plate 2. The spring 6 sleeved on the limiting rod 5 will be stretched or compressed according to the displacement of the movable plate 2 to further buffer the external force. The limiting block 12 cooperates with the limiting groove 13 to prevent the movable plate 2 from excessively displacing and detaching from the movable sleeve 3, thereby realizing the buffering and stretching of the entire protective device within a certain range and effectively protecting the internal cable from excessive stretching or compressive damage.

[0018] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, knobs 16 are provided on both the left and right sides of the fixing sleeve 1. A worm gear 17 is fixedly connected to the side of the knob 16 closest to the fixing sleeve 1. The outer wall of the worm gear 17 is rotatably connected to the snap-fit ​​block 4. A worm wheel 18 is meshed with the outer wall of the worm gear 17. A threaded rod 19 is fixedly connected through the front side of the worm wheel 18. The outer wall of the threaded rod 19 is rotatably connected to the snap-fit ​​block 4. A movable block 21 is threadedly connected to the outer wall of the threaded rod 19. A rotating plate 20 is rotatably connected to both the upper and lower sides of the movable block 21. A snap-fit ​​post 22 is rotatably connected to the other end of the rotating plate 20. A limit plate 23 is fixedly connected to the inner surface of the snap-fit ​​block 4. The outer wall of the limit plate 23 is slidably connected to the snap-fit ​​post 22. The outer wall of the snap-fit ​​post 22 is movably connected to the slot 15. When it is necessary to assemble the protective device, the fixing sleeve... The snap-fit ​​block 4 on the fixed sleeve 1 is aligned with the insertion port 14 on the movable sleeve 3 and inserted. The knobs 16 on the left and right sides of the fixed sleeve 1 are rotated. The knobs 16 drive the worm gear 17 to rotate. The worm gear 17 meshes with the worm wheel 18, which in turn causes the threaded rod 19, which is fixedly connected to the front side of the worm wheel 18, to rotate. The threaded rod 19 is threadedly connected to the movable block 21. When the threaded rod 19 is rotated, the movable block 21 will move along the axial direction of the threaded rod 19 within the snap-fit ​​block 4. The movable block 21 is rotatably connected to the snap-fit ​​post 22 through the rotating plate 20. The movement of the movable block 21 drives the rotating plate 20 to rotate, so that the snap-fit ​​post 22 is inserted into the slot 15 on the inner surface of the insertion port 14. The limiting plate 23 plays a limiting and guiding role for the snap-fit ​​post 22, ensuring that the snap-fit ​​post 22 is accurately inserted into the slot 15, thereby completing the splicing of the protective device, making the protective device easy to transport and handle, and improving construction efficiency.

[0019] The working principle of the deep trench direct burial protection device for the collector cable of this wind farm will be explained in detail below.

[0020] like Figure 1-5As shown, when the protective device is subjected to tensile or compressive forces caused by external ground movement, soil deformation, etc., the movable plate 2 will displace relative to the movable sleeve 3. The rotating plate 7 rotatably connected to the rear of the movable plate 2 will drive the movable block 8 to slide on the fixed rod 10. The damping shock absorber 11 between the two movable blocks 8 can absorb some vibration energy and play a buffering role. At the same time, the limiting rod 5 on the rear side of the inner surface of the movable sleeve 3 slides in the limiting groove 13 on the inner surface of the movable plate 2. The spring 6 sleeved on the limiting rod 5 will be stretched or compressed according to the displacement of the movable plate 2 to further buffer the external force. The limiting block 12 cooperates with the limiting groove 13 to prevent the movable plate 2 from excessively displacing and detaching from the movable sleeve 3, thereby realizing the buffering and stretching of the entire protective device within a certain range, effectively protecting the internal cables from excessive stretching or compressive damage. When splicing is required, When assembling the protective device, align the snap-fit ​​block 4 on the fixed sleeve 1 with the insertion port 14 on the movable sleeve 3 and insert it. Rotate the knobs 16 on the left and right sides of the fixed sleeve 1. The knobs 16 drive the worm gear 17 to rotate. The worm gear 17 meshes with the worm wheel 18, which in turn causes the threaded rod 19, which is fixedly connected to the front of the worm wheel 18, to rotate. The threaded rod 19 is threadedly connected to the movable block 21. When the threaded rod 19 is rotated, the movable block 21 will move along the axial direction of the threaded rod 19 within the snap-fit ​​block 4. The movable block 21 is rotatably connected to the snap-fit ​​post 22 through the rotating plate 20. The movement of the movable block 21 drives the rotating plate 20 to rotate, so that the snap-fit ​​post 22 is inserted into the slot 15 on the inner surface of the insertion port 14. The limiting plate 23 limits and guides the snap-fit ​​post 22, ensuring that the snap-fit ​​post 22 is accurately inserted into the slot 15, thereby completing the splicing of the protective device, making the protective device easy to transport and handle, and improving construction efficiency.
