Description

Technical Field

[0001] This utility model relates to the field of overhead line clamp technology, and in particular to a novel overhead line clamp device with insulating sheathing material. Background Technology

[0002] To reduce power supply failures caused by external factors such as trees, birds, and foreign objects, and to improve power supply reliability, overhead insulated conductors are gradually being used. Insulated overhead conductors refer to a layer of insulation wrapped around the bare conductors of an overhead line to isolate current and prevent direct contact between the current and the external environment or other conductors that should not come into contact with it. Overhead line clamps, as important components for connecting conductors, are hardware used to secure conductors or ground wires on tension towers or guyed towers to ensure stable power transmission. Examples include tension clamps and parallel groove clamps.

[0003] Most existing overhead line clamps are bolt-fastened. Before installation, ensure that the necessary tools (such as wrenches, torque wrenches, screwdrivers, etc.) and clamp components are complete. At the same time, confirm that the conductor specifications match the clamps. Check the clamps and bolts for damage or defects and remove dirt, oxide layers, or burrs from the contact surfaces of the conductor and clamps to ensure good electrical contact. Install the clamp base at the designated position on the pole or support and initially fix it with bolts. Place the conductor into the conductor groove of the clamp, ensuring that the conductor is centered in the groove. Cover the conductor with the pressure plate, ensuring that the contact surface between the pressure plate and the conductor is flat. Tighten the bolts gradually in a diagonal sequence to ensure even pressure distribution.

[0004] Because overhead line clamps are installed using bolt fastening, operators need to manually tighten the bolts. This is especially inconvenient and time-consuming for operators working at heights, increasing installation costs and safety hazards. Metal bolts exposed to outdoor humid and acidic / alkaline environments for extended periods are prone to rusting, leading to decreased tightening force or even loosening, requiring frequent inspection and replacement.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides a novel overhead wire clamp device for insulating sheathing, including a clamp base 1, a shell 2 on the top of the clamp base 1, clamping grooves 3 symmetrically opened on the top of the clamp base 1, an overhead wire 4 inside the clamping grooves 3, a clamping assembly 5 on the top of the clamp base 1, and a locking assembly 6 on the top of the shell 2. The clamping assembly 5 includes a fixed seat 501 fixedly connected to the top of the clamp base 1, a connecting strip 502 rotatably connected inside the fixed seat 501 via a bearing, a clamping plate 503 fixedly connected to one end of the two connecting strips 502 away from each other, an electric push rod 504 fixedly connected to the top of the clamp base 1, a drive seat 505 fixedly connected to the output end of the electric push rod 504, sliding grooves 506 symmetrically opened on both sides of the drive seat 505, and a sliding rod 507 fixedly connected to the end of the connecting strip 502 away from the clamping plate 503, the outer wall of the sliding rod 507 slidingly connected to the inside of the sliding groove 506.

[0030] Specifically, the top of the clamp base 1 has a groove, and the bottom of the electric push rod 504 is fixedly connected to the inside of the groove. The inner sides of the two clamping plates 503 and the inner sides of the clamping groove 3 are coated with a thermochromic coating 7. The thermochromic coating includes a coating substrate coated on the inner sides of the two clamping plates 503 and the inner sides of the clamping groove 3. The coating substrate is made of polyurethane resin or silicone resin. Polyethylene wax is placed inside the coating substrate. Color-changing dye is placed inside the polyethylene wax. The color-changing dye is made of azo dye or quinone dye. The top of the outer shell 2 has an observation groove, and an observation glass 8 is fixedly connected inside the observation groove. When the temperature of the overhead line reaches the set value (80-100℃), the polyethylene wax inside the coating substrate softens and cracks due to heat, thereby releasing the internal color-changing pigment. After contact with the outside, the color changes, forming a visible overheat fault mark.

[0031] Furthermore, when clamping is required, the overhead line 4 is first placed inside the clamping groove 3. The electric push rod 504 is activated to drive the drive seat 505 to rise and fall, which in turn drives the sliding rod 507 to slide in the sliding groove 506, thereby driving the connecting bar 502 to rotate inside the fixed seat 501. The connecting bar 502 then drives the clamping plate 503 to press down and clamp.

[0032] Example 2

[0033] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention. Based on the previous embodiment, the locking component 6 includes two locking grooves 601 symmetrically opened on the top of the outer shell 2. A limiting hole 602 is opened inside the locking groove 601. A locking block 603 is slidably connected inside the locking groove 601. A limiting rod 604 is fixedly connected to the outer wall of the locking block 603. A spring 605 is sleeved on the outer wall of the limiting rod 604. The outer wall of the limiting rod 604 is slidably connected to the inside of the limiting hole 602. Two slots 606 are symmetrically opened on the top of the wire clamp base 1. A locking hole 607 is opened inside the slot 606. A locking rod 608 is fixedly connected to the lower outer wall of the locking block 603. The outer wall of the locking rod 608 is slidably connected to the inside of the locking hole 607. A toggle block 609 is fixedly connected to the top of the locking block 603.

[0034] Specifically, a guide rail is symmetrically fixedly connected inside the locking groove 601. The outer wall of the guide rail is slidably connected to the outer wall of the locking block 603. The lower outer wall of the locking block 603 is slidably connected to the inner side of the slot 606. One end of the spring 605 is fixedly connected to the outer wall of the locking block 603, and the other end of the spring 605 is fixedly connected to the inner wall of the locking groove 601.

[0035] Furthermore, when disassembling the outer casing 2, the locking block 603 is slid by moving the toggle block 609, which in turn causes the locking block 603 to move the limiting rod 604 into the limiting hole 602 and compress the spring 605. At the same time, the locking rod 608 is pulled out from the card hole 607, thereby unlocking the locking of the outer casing 2, which can then be removed directly.

[0036] Specifically, a guide rail is symmetrically fixedly connected inside the locking groove 601. The outer wall of the guide rail is slidably connected to the outer wall of the locking block 603. The lower outer wall of the locking block 603 is slidably connected to the inner side of the slot 606. One end of the spring 605 is fixedly connected to the outer wall of the locking block 603, and the other end of the spring 605 is fixedly connected to the inner wall of the locking groove 601.

[0037] Furthermore, when disassembling the outer casing 2, the locking block 603 is slid by moving the toggle block 609, which in turn causes the locking block 603 to move the limiting rod 604 into the limiting hole 602 and compress the spring 605. At the same time, the locking rod 608 is pulled out from the card hole 607, thereby unlocking the locking of the outer casing 2, which can then be removed directly.

[0038] Working principle: When clamping, first place the overhead line 4 inside the clamping groove 3. Start the electric push rod 504 to drive the drive seat 505 to rise and fall, which in turn drives the sliding rod 507 to slide in the sliding groove 506, thereby driving the connecting bar 502 to rotate inside the fixed seat 501. The connecting bar 502 drives the clamping plate 503 to press down and clamp. When disassembling the outer shell 2, the toggle block 609 drives the locking block 603 to slide, which in turn drives the locking block 603 to drive the limiting rod 604 to slide into the limiting hole 602 and squeeze the spring 605. At the same time, the locking rod 608 is driven out of the card hole 607, thereby unlocking the locking of the outer shell 2, which can then be removed directly.
