Description

Technical Field

[0001] The invention relates to the technical field of power transmission equipment, in particular to a damping spacer rod. Background Art

[0002] With the continuous development of the power grid, people's demand for power transmission capacity continues to increase. However, due to the skin effect of the transmission line, the power transmission capacity is not proportional to the simple increase in the diameter of the transmission line, and the burden of the transmission line itself during operation is increased, which is not conducive to line safety. Therefore, split high-temperature heat-resistant conductors are used in existing high-voltage transmission lines to efficiently improve the transmission capacity of the line. For multi-split conductors, in order to prevent the split conductors from whipping each other, continuously suppress breeze vibration and sub-span oscillation, and ensure the stability of the spacing between the conductors, spacers need to be installed on the split conductors, which can be applied to lines with various split spacings such as two-split, three-split, four-split, six-split, and eight-split.

[0003] However, the existing spacers are only suitable for single-phase split conductors with a specific number of splits, and are not suitable for two-phase split conductors with a variable number of splits. At the same time, the existing spacers are mostly used to suppress sub-span oscillations with single-phase split conductors as the target, and cannot have the vibration reduction effects in the horizontal, vertical and torsional directions. Moreover, most of them are passive vibration reduction and cannot be spontaneously regulated to improve the vibration reduction effect. In addition, the existing interphase spacers are mostly fixed or spring connections with unadjustable stiffness. Summary of the invention

[0004] In view of the above problems existing in the prior art, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is that the existing spacer bars cannot have the vibration reduction effects in the horizontal, vertical and torsional directions and are mostly passive vibration reduction.

[0007] As a preferred solution of the damping spacer rod of the present invention, four first elastic members are provided and are evenly arranged in the frame, and two first heavy balls are provided and are respectively arranged on both sides of the cross bar.

[0008] As a preferred solution of the damping spacer rod of the present invention, two of the second elastic member and two of the second heavy balls are provided and are symmetrically arranged in the cross bar.

[0010] As a preferred solution of the damping spacer rod of the present invention, the third heavy ball is arranged at one end of the third elastic member close to the cross bar.

[0011] As a preferred solution of the damping spacer rod of the present invention, at least two first connection blocks are evenly arranged on the outer ring of the frame, and the first connection blocks are provided with connection holes.

[0012] As a preferred solution of the damping spacer rod of the present invention, it also includes a connecting assembly, which includes an insulator, a first connecting rod and a second connecting rod, one end of the first connecting rod is connected to the frame, and the other end is slidably matched with the second connecting rod.

[0013] As a preferred solution of the damping spacer rod of the present invention, the first connecting rod and the second connecting rod are respectively provided with at least two adjustment holes, and the first connecting rod and the second connecting rod are fixed by bolts inserted into the adjustment holes.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0025] Example 1

[0026] Reference Figure 1 to Figure 4 , is an embodiment of the present invention, which provides a damping spacer bar, and the damping spacer bar includes a frame 100, a cross bar 200 and a rocker rod 300.

[0027] Specifically, refer to Figure 2The frame 100 is annular, in this embodiment, circular, and is composed of two circular light materials, such as aluminum-lithium alloy and titanium-aluminum alloy. The assembled frame 100 has a containing space for placing the first elastic member 101 and the first heavy ball 102. It should be noted that in order to prevent the first elastic member 101 and the first heavy ball 102 from falling out of the frame 100, limit baffles can be installed on both sides of the frame 100.

[0028] In addition, a plurality of first connection blocks 103 are arranged on the outer circumference of the frame 100 . In this embodiment, eleven first connection blocks 103 are arranged and evenly distributed. The first connection blocks 103 are provided with connection holes for installing the wire clamp 500 .

[0029] Further, see Figure 4 , the wire clamp 500 includes a second connection block 501, a sixth elastic member 502, a first clamp 503, and a second clamp 504. The second connection block 501 is fixedly connected to the first connection block 103 by bolts. The two ends of the sixth elastic member 502 are fixedly connected to the second connection block 501 and the first clamp 503 respectively. One end of the second clamp 504 is hinged to the first clamp 503, and the other end is fixedly connected to the first clamp 503 by bolts. The anti-skid pad between the first clamp 503 and the second clamp 504 is used to prevent the wire from sliding. It should also be noted that the sixth elastic member 502 is a high damping rubber spring.

[0030] The first elastic member 101 is also a high damping rubber spring and four of them are arranged in the frame 100, and two of them are arranged in the first weight ball 102. The two first weight balls 102 are arranged on both sides of the cross bar 200, specifically, one is arranged between the two first elastic members 101 on one side of the cross bar 200, and one is arranged between the two first elastic members 101 on the other side of the cross bar 200, and the first weight balls 102 are fixedly connected to the ends of the first elastic members 101. When the frame 100 is twisted, the first weight balls 102 will move and act on the first elastic member 101 to dissipate energy.

[0031] The cross bar 200 is arranged along the diameter direction of the frame 100 and is fixed to the frame 100 at both ends by bolts. The interior of the cross bar 200 is hollow and is equipped with two second elastic members 201. A second weight ball 202 is fixed to the end of each second elastic member 201 and is symmetrical about the center of the cross bar 200. The second elastic member 201 is also a high damping rubber spring. When the frame 100 vibrates in the horizontal direction, the second weight ball 202 moves and acts on the second elastic member 201 to dissipate energy.

[0032] One end of the swing rod 300 is hinged to the center of the crossbar 200, and the other end is fixedly connected to one of the first weight balls 102. The inside of the swing rod 300 is hollow, and a third elastic member 301 and a third weight ball 302 are arranged inside. When the frame 100 is twisted, the third weight ball 302 will start to move away from the center of the frame 100 and squeeze the third elastic member 301 due to the centrifugal effect. The swing rod 300 drives the first weight ball 102 and the third weight ball 302 to generate huge inertial mass. The faster the twisting speed, the greater the centrifugal force and the greater the inertial mass. At the same time, the second weight ball 202 will move and act on the second elastic member 201 to dissipate energy. The spring-type inertial container is combined with the high-damping rubber spring energy dissipation to achieve semi-active control.

[0033] Preferably, the swing rod 300 is divided into an upper swing rod 300a, a lower swing rod 300b and a fourth elastic member 300c. The upper swing rod 300a is hinged to the middle part of the cross bar 200, and the lower swing rod 300b is fixedly connected to the first weight ball 102. The second elastic member 201 and the second weight ball 202 are installed in the lower swing rod 300b. The two ends of the fourth elastic member 300c are fixedly connected to the upper swing rod 300a and the lower swing rod 300b respectively. When the torsion frequency of the frame 100 increases, the lower swing rod 300b will be moved to a position away from the center of the frame 100 under the action of centrifugal force, and the first weight ball 102 will be pressed against the inner wall of the frame 100, thereby increasing the friction of the first weight ball 102 and achieving better energy dissipation.

[0034] Further, see Figure 3 The spacer bar also includes a connection assembly 400, and the above structure is symmetrically arranged at both ends of the connection assembly 400. The connection assembly 400 includes an insulator 401, a first connection rod 402 and a second connection rod 403. The first connection rod 402 is fixedly connected to the frame 100 by bolts. The other end is slidably matched with the second connection rod 403, and the second connection rod 403 is arranged inside the first connection rod 402. And a plurality of adjustment holes are evenly arranged on the first connection rod 402 and the second connection rod 403, respectively, and the telescopic length of the second connection rod 403 can be controlled by the adjustment holes.

[0035] Preferably, the second connecting rod 403 is composed of an upper rod 403a, a lower rod 403b and a fifth elastic member 403c. The upper rod 403a is slidably matched with the first connecting rod 402, the lower rod 403b is fixedly connected to the insulator 401, and the two ends of the fifth elastic member 403c are respectively fixedly connected to the upper rod 403a and the lower rod 403b.

[0036] Preferably, the fifth elastic member 403c includes an inner elastic member 403c-1 and an outer elastic member 403c-2, wherein the inner elastic member 403c-1 is a rigid spring and the outer elastic member 403c-2 is a high damping rubber spring. When the frame 100 vibrates in the vertical direction, the fifth elastic member 403c can dissipate energy thereof.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
