Description
Technical Field
[0001] This utility model relates to the field of wind farm collector line protection technology, and in particular to a wind farm collector line protection device. Background Technology
[0002] The wind farm collector line is a power transmission system that collects and transmits the power from the high-voltage side of the box-type substation associated with each wind turbine to the wind farm step-up substation. The wind farm collector line protection device is a device that protects the wind farm collector line during use. Traditional collector line protection generally lacks selectivity and is prone to cascading tripping accidents, leading to an expansion of the power outage area. Therefore, a wind farm collector line protection device is used.
[0003] A search revealed a Chinese patent publication number, CN221767570U, which discloses a wind farm power collection line protection device, comprising a tower body connected to a transmission line; a diversion component, the diversion component including a diversion line and an auxiliary connecting component, one end of the diversion line being connected to the transmission line, one end of the auxiliary connecting component being connected to the side of the diversion line, and the other end being connected to the transmission line; the auxiliary connecting component including an auxiliary connecting line, a first connecting member, and a second connecting member, one end of the auxiliary connecting line being detachably connected to the first connecting member, and the other end being detachably connected to the second connecting member.
[0004] In the aforementioned utility model, by first connecting the diversion line to the power transmission line, and then adding an auxiliary connecting component between the diversion line and the power transmission line, the auxiliary connecting component remains connected to the power transmission line even after the diversion line detaches in a strong wind environment, thereby preventing the diversion line from falling off the power transmission line and achieving the technical effect of preventing tripping. However, in actual use, the auxiliary windproof guy wire requires a large space and may still fail under extreme wind speeds, which may still cause the diversion line to fall off. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a wind farm collector line protection device, which aims to improve the problem that auxiliary windproof guy wires require a large space and may still fail under extreme wind speeds, causing the diversion wire to fall off.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wind farm power collection line protection device includes a tower. A support frame is fixedly connected to the outer wall of the tower. A cover is slidably connected to the outer wall of the support frame. A ventilated plate is fixedly connected to the inside of the cover. A fixing plate is fixedly connected to the outer wall of the ventilated plate. A first sliding column is fixedly connected to the outer wall of the fixing plate. A sleeve is slidably connected to the outer wall of the first sliding column. A spring is slidably connected to the outer wall of the sleeve. One end of the spring is fixedly connected to the outer wall of the fixing plate. A buffer plate is fixedly connected to the outer wall of the buffer plate. A second sliding column is fixedly connected to the outer wall of the second sliding column and slidably connected to the inside of the sleeve. A power transmission assembly is installed inside the tower.
[0008] The above technical solution works as follows: when the cover is impacted by the airflow, the buffer plate receives the impact force and compresses the second sliding column, causing it to slide inside the sleeve. At the same time, it pushes the sleeve to slide on the outer wall of the first sliding column. Meanwhile, the spring will continuously squeeze and rebound during this process, thereby absorbing the impact force of the external airflow and reducing the impact on the internal structure and the drainage line.
[0009] As a further description of the above technical solution:
[0010] The power transmission assembly includes a power transmission line, the outer wall of which is disposed inside the tower, and the internal electrical connection of the power transmission assembly includes a drain wire.
[0011] The above technical solution allows current to be guided to the diversion line via the transmission line, and the current can be evenly guided and distributed via the diversion line.

[0013] The outer wall of the cover is fixedly connected to an insert plate, the outer wall of the insert plate is slidably connected to the inside of the support frame, and the inner wall of the cover is fitted with a rubber pad.
[0014] The above technical solution allows for the insertion of the insert plate into the support frame, which limits the position between the cover and the support frame, making the connection and fixation more stable. The rubber pads can also absorb the impact of airflow.
[0015] As a further description of the above technical solution:
[0016] The support frame has a sliding groove inside, and a threaded column is rotatably connected inside the support frame.
[0017] Through the above technical solution: the slide groove plays a limiting role, preventing the block from deviating during the sliding process, and the support frame supports the threaded column.
[0018] As a further description of the above technical solution:
[0019] A rotating block is fixedly connected to the outer wall of the threaded column, and a locking block is threadedly connected to the outer wall of the threaded column.
[0020] The above technical solution allows the threaded column to rotate synchronously by rotating the rotating block, and the threaded column allows the locking block to slide synchronously against the slide groove.
[0021] As a further description of the above technical solution:
[0022] The outer wall of the card block is slidably connected to the inner wall of the slide groove, and the inside of the card block is provided with a card slot.
[0023] Through the above technical solution, the sliding groove can effectively limit the sliding trajectory of the card block, and the design of the card groove can facilitate the limiting and fixing of the connecting column.
[0024] As a further description of the above technical solution:
[0025] A connecting rod is fixedly connected inside the cover, and the outer wall of the connecting rod is slidably connected to the inside of the support frame. A connecting column is fixedly connected to the outer wall of the connecting rod.
[0026] Through the above technical solution: the cover plays a role in fixing the connecting rod, the connecting rod plays a role in fixing the connecting column, and aligning the cover with the support frame allows the connecting rod and the connecting column to slide into the support frame.
[0027] As a further description of the above technical solution:
[0028] The outer wall of the connecting column is slidably connected to the inside of the support frame, and the outer wall of the connecting column is slidably connected to the inner wall of the slot.
[0029] The above technical solution allows the inner wall of the slot to fit against the outer wall of the connecting post, enabling the connecting post to be locked and fixed within the slot.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, when the cover is impacted by airflow, the wind energy is absorbed by the spring through the cooperation between the fixing plate, the first sliding column, the sleeve, the spring, the second sliding column and the buffer plate, thereby effectively absorbing the impact of airflow and extending the service life of the device.
[0032] 2. In this utility model, the rotating block drives the threaded column to rotate. Through the cooperation between the connecting rod, the connecting block, the rotating block and the locking block, the locking block locks and fixes the connecting column, thus completing the installation of the cover and the support frame. This achieves the goal of quickly installing and using the support frame and the cover, protecting the internal drainage line, effectively preventing the drainage line from falling under extremely high wind speeds, and reducing the number of fault trips.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a wind farm power collection line protection device, including a tower 1, a support frame 2 fixedly connected to the outer wall of the tower 1, a cover 3 slidably connected to the outer wall of the support frame 2, a ventilated plate 4 fixedly connected to the inside of the cover 3, a fixed plate 5 fixedly connected to the outer wall of the ventilated plate 4, a first sliding column 6 fixedly connected to the outer wall of the fixed plate 5, a sleeve 7 slidably connected to the outer wall of the first sliding column 6, a spring 8 slidably connected to the outer wall of the sleeve 7, one end of the spring 8 fixedly connected to the outer wall of the fixed plate 5, a buffer plate 10 fixedly connected to the other end of the spring 8, a second sliding column 9 fixedly connected to the outer wall of the buffer plate 10, and the outer wall of the second sliding column 9 slidably connected to the inside of the sleeve 7. A power transmission assembly 11 is provided inside the tower 1.
[0043] Specifically, the tower 1 provides support and fixation for the support frame 2. The enclosure 3 is installed and used with the support frame 2. The enclosure 3 protects the internal airflow line 1102. The enclosure 3 has a ventilated plate 4 inside, which facilitates the dissipation of heat from inside the enclosure 3 to the outside and provides dust protection. The fixing plate 5 is fixed to the outer wall of the ventilated plate 4, fixing the first sliding column 6. The sleeve 7 connects the first sliding column 6 and the second sliding column 9. The second sliding column 9 fixes the buffer plate 10. When external airflow reaches the buffer plate 10... The buffer plate 10 will squeeze and push the second sliding column 9, causing it to slide inside the sleeve 7. At the same time, the sleeve 7 will also slide on the outer wall of the first sliding column 6. The spring 8 is set between the fixed plate 5 and the buffer plate 10 and will be squeezed due to the sliding of the buffer plate 10. When the wind force acts on the spring 8, the elastic potential energy of the spring 8 increases. When the external force disappears, the spring 8 returns to its original shape, converting the stored elastic potential energy into kinetic energy and gradually releasing it. Through the elastic deformation of the spring 8, the transmission of wind force can be significantly reduced, and the wind energy can be absorbed, thereby reducing the impact force on the guide line 1102 and preventing detachment.
[0044] Reference Figure 4 The power transmission assembly 11 includes a power transmission line 1101, the outer wall of which is disposed inside the tower 1, and the internal electrical connection of the power transmission assembly 11 is a drain line 1102.
[0045] Specifically, the transmission line 1101 is used to transmit the electrical energy generated by the power plant from the power station to the substation or user end, and to transmit the current to the diversion line 1102. The diversion line 1102 then distributes the current to multiple branch lines to ensure the uniform distribution of the current on different paths.
[0046] Reference Figure 2 The outer wall of the cover 3 is fixedly connected to the insert plate 12, the outer wall of the insert plate 12 is slidably connected to the inside of the support frame 2, and the inner wall of the cover 3 is fitted with a rubber pad 20.
[0047] Specifically, the cover 3 serves to fix the insert plate 12. By sliding the insert plate 12 into the support frame 2, the cover 3 and the support frame 2 can be limited and fixed, making the connection between the cover 3 and the support frame 2 more stable. The design of the rubber pad 20 can effectively absorb the impact of airflow and reduce damage to the drainage line 1102 and the internal structure.
[0048] Reference Figure 5 and Figure 6 The support frame 2 has a sliding groove 15 inside, and a threaded column 16 is rotatably connected inside the support frame 2; a rotating block 17 is fixedly connected to the outer wall of the threaded column 16, and a locking block 18 is threadedly connected to the outer wall of the threaded column 16; the outer wall of the locking block 18 is slidably connected to the inner wall of the sliding groove 15, and a locking groove 19 is opened inside the locking block 18; a connecting rod 13 is fixedly connected to the inside of the cover 3, and the outer wall of the connecting rod 13 is slidably connected to the inside of the support frame 2; a connecting column 14 is fixedly connected to the outer wall of the connecting rod 13; the outer wall of the connecting column 14 is slidably connected to the inside of the support frame 2, and the outer wall of the connecting column 14 is slidably connected to the inner wall of the locking groove 19;
[0049] Specifically, the support frame 2 supports the threaded column 16, and the threaded column 16 fixes the rotating block 17. By rotating the rotating block 17, the threaded column 16 can be driven to rotate stably inside the support frame 2. The threaded column 16 is threadedly connected to the locking block 18. When the threaded column 16 rotates, the locking block 18 can slide against the inner wall of the slide groove 15. The design of the slide groove 15 can limit the movement of the locking block 18. The locking block 18 has a slot 19 inside that can engage with the connecting column 14. The connecting rod 13 connects the cover 3 and the connecting column 14. When it is necessary to fix the support frame 2 and the cover 3, the cover 3 can be aligned with the support frame 2. At this time, the connecting rod 13 and the connecting column 14 will enter the interior of the support frame 2. By sliding the locking block 18, the connecting column 14 can be locked into the inner wall of the slot 19 and locked in place. This completes the fixation of the cover 3 and the support frame 2. The simple installation facilitates quick use.
[0050] Working principle: When the protective device is needed, the cover 3 is installed and used. Rotating the rotating block 17 drives the threaded column 16 to rotate. When the threaded column 16 rotates, it will drive the outer wall locking block 18 to slide against the inner wall of the slide groove 15. At this time, the cover 3 can be aligned with the support frame 2. At this time, the insert plate 12 will be inserted into the inside of the support frame 2. The connecting rod 13 and the connecting column 14 are inserted into the inside of the support frame 2. Rotating the rotating block 17 in the opposite direction drives the threaded column 16 to rotate. The rotation of the threaded column 16 can drive the locking block 18 to slide in the opposite direction, so that the locking blocks 18 on both sides lock the connecting column 14, and fix the support frame 2 and the cover 3. This achieves quick installation and use of the support frame 2 and the cover 3, thereby protecting the internal drain line 1102 and effectively preventing the drain line 1102 from falling under extremely high wind speeds, reducing the number of fault trips.
[0051] When the cover 3 and the vent plate 4 are blown by the airflow, the airflow is transmitted to the surface of the buffer plate 10, causing it to push the second sliding column 9 to slide inside the sleeve 7. At the same time, the sleeve 7 will slide on the outer wall of the first sliding column 6, and the spring 8 will be squeezed during the sliding process. Through the continuous rebound and reset of the spring 8, the impact of the external airflow can be absorbed. The rubber pad 20 set on the inner wall of the cover 3 can also absorb the impact of the airflow, thus effectively absorbing the impact of the airflow and extending the service life of the device. This device can not only quickly install and use the support frame 2 and the cover 3, thereby protecting the internal drainage line 1102 and effectively preventing the drainage line 1102 from falling under the maximum wind speed, reducing the number of fault trips, but also effectively absorb the impact of the airflow and extend the service life of the device.
[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
