Description

Technical Field

[0001] This invention relates to the field of spacer technology, specifically to a spacer structure for distribution network lines. Background Technology

[0002] Phase-to-phase spacers installed on power transmission lines are used to maintain a certain distance between phase conductors. This allows irregular conductor vibrations to cancel each other out and release, preventing conductors from coming into contact and discharging, or causing larger accidents due to excessive vibrations. However, existing phase-to-phase spacers are rigidly installed on the conductors using fittings on both sides. Irregular conductor vibrations can easily cause the insulating spacers to break or the fittings to crack. For a given line specification, matching fittings are required, resulting in poor versatility. Furthermore, fixing the fittings to the line is cumbersome and lacks stability. Therefore, how to structurally improve existing phase-to-phase spacers to effectively control conductor vibrations and ensure line stability has become an urgent problem to be solved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a distribution network line spacer structure that can quickly clamp and fix the line, is suitable for lines of different specifications, is flexible and convenient to operate, has a wide range of applications, reduces line galloping, and has good performance. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a distribution network line spacer structure, comprising an insulating rod, both ends of which are provided with connecting plates, one end of which is provided with a connecting rod, a locking sleeve fitted onto the connecting rod, and a self-locking nut for pushing the locking sleeve threaded onto the connecting rod; the connecting rod is inserted into a retainer, the retainer comprising an L-shaped retaining plate, the upper side plate of the retaining plate having a retaining groove, the vertical side plate of the retaining plate having a protruding wedge-shaped block on the side facing the retaining groove, the vertical side plate of the retaining plate having a slot adapted to the connecting rod, and the end of the locking sleeve having a tapered surface adapted to the wedge-shaped block; when the self-locking nut is rotated, the locking sleeve moves axially along the connecting rod and pushes the wedge-shaped block, and the retainer moves, causing the retaining groove and the locking sleeve to approach each other and secure the distribution network line.

[0005] Preferably, the connecting plate has a through hole for the insulating rod to pass through, and the connecting plate is connected to the insulating rod by two nuts, which are located on both sides of the connecting plate and are threaded to the insulating rod.

[0006] Preferably, the locking sleeve and the connecting rod are clearance-fitted, and the outer wall of the locking sleeve is fitted with a rubber sleeve.

[0007] Preferably, the slot passes through the vertical side plate of the card plate and the wedge block, and the slot extends to the end of the vertical side plate of the card plate.

[0008] Preferably, the insulating rod comprises two rods, with a buffer spring connecting the two rods.

[0009] Preferably, the surface of the slot is covered with a rubber pad, and the slot is a trapezoidal slot or a V-shaped slot.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the slot of the card holder contacts the line, and by tightening the locking nut, the locking nut pushes the locking sleeve to move. When the locking sleeve moves axially along the connecting rod, the conical surface of the locking sleeve contacts the wedge block of the card holder and causes the card holder to move. Then the slot and the locking sleeve move closer to each other and fasten the line, thereby quickly achieving the clamping and fixing of the line. The operation is flexible and convenient. The use of the slot and the locking sleeve to fix the line can be applied to lines of different specifications and has a wide range of applications. In addition, a buffer spring is set in the middle of the insulating rod to reduce line movement and improve the performance. Attached Figure Description

[0015] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0016] Please see Figure 1-3This invention provides a technical solution: a distribution network line spacer structure, including an insulating rod 1, with connecting plates 2 at both ends of the insulating rod 1, and a connecting rod 6 at one end of the connecting plate 2. A locking sleeve 5 is sleeved on the connecting rod 6, and a self-locking nut 7 for pushing the locking sleeve 5 is threaded onto the connecting rod 6. A card seat 4 is inserted into the connecting rod 6, and the card seat 4 includes an L-shaped card plate 4.1. The upper side plate of the card plate 4.1 has a slot 4.4, and the vertical side plate of the card plate 4.1 has a protruding wedge block 4.3 on the side facing the slot 4.4. The vertical side plate of the card plate 4.1 has a slot 4.2 that is adapted to the connecting rod 6. The end of the locking sleeve 5 has a conical surface 5.2 that is adapted to the wedge block 4.3. When the self-locking nut 7 is rotated, the locking sleeve 5 moves axially along the connecting rod 6 and pushes the wedge block 4.3. When the card seat 4 moves, the slot 4.4 and the locking sleeve 5 approach each other and fasten the distribution network line.

[0017] It is understandable that the slot 4.4 of the card holder 4 contacts the line. By tightening the locking nut 7, the locking nut 7 pushes the locking sleeve 5 to move. When the locking sleeve 5 moves axially along the connecting rod 6, the conical surface 5.2 of the locking sleeve 5 contacts the wedge block 4.3 of the card holder 4, causing the card holder 4 to move. Then the slot 4.4 and the locking sleeve 5 move closer to each other and fasten the line, thus enabling quick clamping and fixing of the line. The operation is flexible and convenient. The use of the slot 4.4 and the locking sleeve 5 to fix the line is applicable to different specifications of lines and has a wide range of applications.

[0018] Furthermore, the connecting plate 2 is provided with a through hole 2.1 for the insulating rod 1 to pass through. The connecting plate 2 is connected to the insulating rod 1 by two nuts 3. The two nuts 3 are located on both sides of the connecting plate 2 respectively. The nuts 3 are threadedly connected to the insulating rod 1. The position of the connecting plate 2 can be adjusted by the two nuts 3, and the spacing between the two connecting plates 2 can be changed. It is suitable for phase-to-phase lines with different spacings and is flexible and convenient to use.

[0019] Furthermore, the locking sleeve 5 and the connecting rod 6 are fitted with a clearance, and a rubber sleeve 5.1 is fitted on the outer wall of the locking sleeve 5. The rubber sleeve 5.1 contacts the circuit to prevent the locking sleeve 5 from being hard squeezed against the circuit and damaging it.

[0020] Furthermore, the slot 4.2 penetrates the vertical side plate of the card plate 4.1 and the wedge block 4.3, and the slot 4.2 extends to the end of the vertical side plate of the card plate 4.1. The card holder 4 can be separated from the connecting rod 6 through the slot 4.2. That is, during installation, first align the card slot 4.4 of the card holder 4 with the circuit, then insert the connecting rod 6 into the slot 4.2, then put on the locking sleeve 5, and then tighten the self-locking nut 7 to make the card holder 4 and the locking sleeve 5 cooperate to fix the circuit. The operation is convenient.

[0021] Furthermore, the insulating rod 1 includes two rods, and a buffer spring 1.1 is connected between the two rods, which can absorb kinetic energy, buffer and dissipate vibration, and reduce line galloping;

[0022] Furthermore, the surface of the slot 4.4 is covered with a rubber pad, which makes soft contact with the circuit and reduces damage to the circuit. The slot 4.4 is a trapezoidal slot or a V-shaped slot, which makes it easy to clamp the circuit.

[0023] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes that fall within the meaning and scope of equivalents in the content of this invention.
