Technical Field
[0001] The invention belongs to the technical field of power grid equipment, and in particular relates to a 10-35KV line stabilizer. Background Art
[0002] The 10-35KV line is a very commonly used transmission line in the power grid, but this power line is prone to independent wind deflection and wind dance of each phase line under the natural effect of wind. On the one hand, the wind deflection and wind dance of each phase line will cause phase-to-phase short circuit of the line, resulting in large-scale power outages, which will bring huge manpower and material resources to line maintenance and troubleshooting. On the other hand, with the long-term effect of wind deflection and wind dance, it is very easy to cause an increase in the phenomenon of broken strands of the conductor due to natural stress, increasing the maintenance and operation costs. The above problems will not only have a serious impact on the production and life of the people due to power outages, but also cause a sharp increase in maintenance costs, adding unnecessary burdens to the power sector. Summary of the invention
[0003] In view of the wind deviation and wind dancing problems existing in the existing 10-35KV lines, the present invention provides a 10-35KV line stabilizer, comprising: a length adjustment mechanism horizontally set at a central position, and two insulating rods, two length locking mechanisms, two horizontal connecting rods, two insulating pressure-bearing mechanisms, and two locks symmetrically set horizontally at both ends of the length adjustment mechanism. The length locking mechanism is used to lock the length of the length adjustment mechanism. One end of the insulating pressure-bearing mechanism is fixedly connected to the length adjustment mechanism through an insulating rod, and the other end is detachably fixedly connected to the lock through a horizontal connecting rod. The lock is an insulator and is used to lock the line stabilizer on the 10-35KV line.
[0004] Furthermore, the lock head includes: a lock sleeve, an inner lock and a lock cover.
[0005] Furthermore, the lock sleeve is a hollow cylindrical hard structure with a cylindrical concave groove. The top of the concave groove is open.

[0006] Furthermore, the inner lock is a cylindrical insulating cylinder matching the inner concave groove of the lock sleeve. The inner lock is installed in the inner concave groove of the lock sleeve and is provided with a second through groove in the vertical direction.
[0007] Furthermore, the lock cover is located at the open end of the lock sleeve, and a groove matching the lock sleeve is provided on the side facing the lock sleeve. The lock cover has an external thread on the groove. The lock cover has a third through groove in the vertical direction. The lock cover 2 has a circular opening on the end facing away from the lock sleeve 1; the diameter of the circular opening is smaller than the cross-sectional diameter of the inner lock 9, and is connected to the groove and the third through groove 203.
[0008] Furthermore, the inner thread of the lock cover and the outer thread of the lock cover match and are screwed together. The widths of the first through slot, the second through slot and the third through slot are all greater than or equal to the outer diameter of the 10-35KV line.
[0009] Furthermore, the height of the inner lock is L, the length of the inner concave slot of the lock sleeve is H, and L and H satisfy A = LH. The length of the inner thread of the lock cover is B, the length of the outer thread of the lock cover is C, and B and C satisfy CB = A. The value of A is 0.1-10 cm.
[0010] Furthermore, the bottom end of the inner concave hollow groove of the lock sleeve is a semi-enclosed structure with a circular hole. The diameter of the circular hole is smaller than the cross-sectional diameter of the inner lock. The first through groove is connected to the circular hole. The bottom end of the second through groove and the hole edge of the circular hole converge at D. The D is greater than or equal to the outer diameter of the 10-35KV line.
[0011] Furthermore, the bottom end of the second through groove is an arc structure. The curvature of the arc matches the curvature of the outer wall of the 10-35KV line. The D is equal to the outer diameter of the 10-35KV line.
[0012] Furthermore, the end of the horizontal connecting rod facing the lock head is provided with a second external thread.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0024] Example 1
[0025] A 10-35KV line stabilizer, such as Figure 1 As shown, it includes: a length adjustment mechanism 6 horizontally set at the center position, and two insulating rods 5, two length locking mechanisms 7, two horizontal connecting rods 3, two insulating pressure-bearing mechanisms 4, and two locks symmetrically set horizontally at both ends of the length adjustment mechanism 6. The length locking mechanism 7 is used to lock the length of the length adjustment mechanism 6. One end of the insulating pressure-bearing mechanism 4 is fixedly connected to the length adjustment mechanism 6 through the insulating rod 5, and the other end is detachably fixedly connected to the lock through the horizontal connecting rod 3. The lock is an insulator and is used to lock the line stabilizer on the 10-35KV line.
[0026] The use process of the device is as follows: first, a section of the lock is locked on a phase line of the 10-35KV line, then the length locking mechanism 7 is released, and the length adjusting mechanism 6 is adjusted so that the lock at the other end can be locked on another phase line of the 10-35KV line, and then the length locking mechanism 7 is adjusted to lock the length of the length adjusting mechanism 6, so as to complete the mutual isolation and locking between the two phase lines in the 10-35KV line. Finally, the 10-35KV line stabilizer is hung between the phase lines in sequence as needed, so that the mutual isolation of each phase line in the 10-35KV line can be achieved. Since the length adjusting mechanism 6 and the horizontal connecting rod 3 are rigid mechanisms, and the insulating pressure bearing mechanism 4 is a rigid or flexible mechanism with bearing capacity, the 10-35KV line stabilizer is hung between the phase lines to support each phase line. Since the lock is an insulator and the insulating pressure bearing mechanism 4 also has an insulating effect, the 10-35KV line stabilizer is hung between the phase lines without causing a short circuit between the phase lines.
[0027] Example 2
[0028] Based on the 10-35KV line stabilizer described in Example 1, Figure 2 , Figure 3 and Figure 4 As shown, the lock head comprises: a lock sleeve 1, an inner lock 8 and a lock cover 2.
[0029] The lock sleeve 1 is a hollow cylindrical hard structure with a cylindrical concave groove. The top of the concave groove is open. The outer wall of the lock sleeve 1 is provided with a lock cover internal thread 101 near the opening of the concave groove. A first through groove 103 is opened on the outer wall of the lock sleeve 1 in the vertical direction. The bottom end of the concave groove is a semi-closed structure with a circular hole 104. The diameter of the circular hole 104 is smaller than the cross-sectional diameter of the inner lock 8. The first through groove 103 is connected to the circular hole 104. The bottom end of the second through groove 801 and the edge of the circular hole 104 meet at D. The D is greater than or equal to the outer diameter of the 10-35KV line.
[0030] The inner lock 8 is a cylindrical insulating cylinder matching the inner concave groove of the lock sleeve 1. The inner lock 8 is installed in the inner concave groove of the lock sleeve 1 and is provided with a second through groove 801 in the vertical direction.
[0031] The lock cover 2 is located at the open end of the lock sleeve 1, and a groove matching the lock sleeve 1 is provided on the side facing the lock sleeve 1. The lock cover 2 is provided with a third through groove 203 in the vertical direction. The groove is provided with a lock cover external thread 202. The lock cover 2 is provided with a circular opening at the end facing away from the lock sleeve 1; the diameter of the circular opening is smaller than the cross-sectional diameter of the inner lock 8, and is connected with the groove and the third through groove 203. The lock cover internal thread 101 and the lock cover external thread 202 are matched and screwed.
[0032] The widths of the first through slot 103 , the second through slot 801 , and the third through slot 203 are all greater than or equal to the outer diameter of the 10-35KV line.
[0033] The use process of the lock is as follows: first, install the inner lock 8 in the concave slot of the lock sleeve 1, and rotate the inner lock 8 so that the second slot 801 overlaps with the first slot 103. Then, pass a phase line of the 10-35KV line through the first slot 103 and insert it into the second slot 801. Then, rotate the inner lock 8 to separate the second slot 801 from the first slot 103, and the phase line is stuck between the second slot 801 and the inner wall of the concave slot. Then, pass the third slot 203 of the phase line self-locking cover 2 through the open end of the concave slot of the self-locking sleeve 1, so that the phase line is located in the circular opening of the lock cover 2. Finally, rotate the lock cover 2 so that the top of the concave slot of the self-locking sleeve 1 is screwed and tightened with the lock sleeve 1. At this time, the phase line is stuck between the second slot 801 and the inner wall of the circular opening, thereby forming a lock between the lock and the phase line.
[0034] Example 3
[0035] Based on the 10-35KV line stabilizer described in Example 2, Figure 2 As shown, the height of the inner lock 8 is L, the length of the hollow recess in the lock sleeve 1 is H, and L and H satisfy A = LH. The length of the inner thread 101 of the lock cover is B, and the length of the outer thread 202 of the lock cover is C, and B and C satisfy CB = A. The value of A is 0.1-10 cm.
[0036] This arrangement allows the inner lock 8 to be placed in the inner recessed groove of the lock sleeve 1 at a height higher than the top A of the inner recessed groove. At this time, when the lock cover 2 and the lock sleeve 1 are screwed together and tightened, the lock cover 2 exerts downward pressure friction on the inner lock 8, thereby increasing the difficulty of free rotation of the inner lock 8, improving the locking stability of the lock head, and preventing the lock head from falling off the phase line.
[0037] Example 4
[0038] Based on the 10-35KV line stabilizer described in Example 2, Figure 3 and Figure 4 As shown, the bottom end of the second through slot 801 is an arc structure. The arc matches the arc of the outer wall of the 10-35KV line. The bottom end of the second through slot 801 and the edge of the circular hole 104 converge at D. The D is equal to the outer diameter of the 10-35KV line. This setting can make the phase line stably stuck between the bottom end of the second through slot 801 and the edge of the circular hole 104, avoiding the wear of the outer surface of the phase line caused by the sliding of the phase line.
[0039] Example 5
[0040] Based on the 10-35KV line stabilizer described in Example 2, Figure 2 As shown, the end of the horizontal connecting rod 3 facing the lock head is provided with a second external thread 301. A through hole connected to the inner concave groove is opened in the horizontal direction on the outer wall of the lock sleeve 1. The through hole matches the horizontal connecting rod 3 and is provided with a second internal thread 102 screwed to the second external thread 301. At this time, the horizontal connecting rod 3 is screwed and fixed to the lock sleeve 1, and the horizontal connecting rod 3 or the lock sleeve 1 can be continuously rotated after the horizontal connecting rod 3 is screwed to the lock sleeve 1, so that the rod head of the horizontal connecting rod 3 contacts the inner lock 8 and forms extrusion friction, thereby fixing the inner lock 8 to prevent its free rotation from causing the phase line to fall off.
[0041] Example 6
[0042] Based on the 10-35KV line stabilizer described in Example 2, an anti-slip pattern 201 is provided on the vertical outer side wall of the lock cover 2 .
[0043] Example 7
[0044] Based on the 10-35KV line stabilizer described in Example 1, the insulating pressure-bearing mechanism 4 is a horizontally arranged cylindrical silicone sleeve. The insulating pressure-bearing mechanism 4 is provided with 2-10 anti-creeping umbrella pieces 401 in radial order, preferably 5. The anti-creeping umbrella piece 401 is arranged along the cross-sectional direction of the insulating pressure-bearing mechanism 4 and is truncated. The anti-creeping umbrella piece 401 is mainly used to prevent the current between the two phase lines from being interconnected through the line stabilizer. Secondly, when the insulating pressure-bearing mechanism 4 is deformed by force, they can approach each other to form a force sharing, effectively alleviating the lateral deformation internal stress of the insulating pressure-bearing mechanism 4.
[0045] Example 8
[0046] Based on the 10-35KV line stabilizer described in Example 1, the length adjustment mechanism 6 includes: a hard hollow pipe sleeve 602 provided with a first internal thread 601. The two insulating rods 5 symmetrically and horizontally arranged at both ends of the length adjustment mechanism 6 are respectively provided with a first external thread 501 at one end, and are respectively inserted into the hard hollow pipe sleeve 602. The first internal thread 601 matches the first external thread 501 and forms a threaded connection. The length locking mechanism 7 is a locking nut threaded on the insulating rod 5. At this time, when it is necessary to adjust the length of the length adjustment mechanism 6, it is only necessary to first loosen the locking nut, then rotate the insulating rod 5 so that it moves inward (shortened) or outward (lengthened) in the horizontal direction relative to the hard hollow pipe sleeve 602, and finally tighten the locking nut again so that the insulating rod 5 cannot rotate relative to the hard hollow pipe sleeve 602 to complete the length adjustment.
[0047] The advantages of the present invention are: the line stabilizer of the present invention can be used as an insulator to isolate and support the conductor, so that the three-phase conductor will not be deflected or fluttered by the natural wind, thereby isolating the phase-to-phase short circuit problem caused by the phase line wind deflection and flutter, and preventing the natural stress strand breakage caused by the wind deflection and flutter. It brings convenience to line inspection and fault elimination, prolongs the service life of the conductor, and reduces the consumption of a large amount of manpower, financial resources and material resources required due to conductor defects. It can play a very good role, especially in mountainous areas where inspection and fault elimination are difficult.
[0048] In addition, the present invention can adjust the length of the line stabilizer at any time according to needs to adapt to the three-phase line isolation support function under different line layouts.
[0049] It should be noted and understood that various modifications and improvements can be made to the invention described in detail above without departing from the spirit and scope of the claims of the present invention. Therefore, the scope of the claimed technical solution is not limited by any specific exemplary teaching given.
