Description

Technical Field

[0001] This utility model belongs to the technical field of overhead line equipment for power distribution networks, and relates to a special insulating baffle for utility poles. Background Technology

[0002] Insulating barriers are flat plates made of insulating material used to isolate live parts on the top of utility poles, restrict the movement of workers, and prevent access to high-voltage live parts. As a commonly used tool in the construction of overhead power distribution lines, insulating barriers serve as an important safety barrier for workers operating overhead power distribution lines.

[0003] Existing insulating barriers typically consist of a barrier, a locking mechanism, a rope around the pole, and an upper hook. The barrier is secured to the utility pole via the rope and hook to isolate the work area from live wires. However, after installation, existing pole-mounted insulating barriers leave a gap between the two halves, preventing complete enclosure. Furthermore, the friction between the insulating barrier and the upper hook decreases over time, causing the pole to tip over during suspension operations. The anti-fall nuts must be tightened again before normal operation can resume.

[0004] To address this issue, a special insulating baffle for utility poles was designed to overcome the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a special insulating baffle for utility poles that is simple and reasonable in structure, firmly assembled, easy to install and disassemble, and safe and stable.

[0006] This utility model is achieved through the following technical solution: a special insulating baffle for utility poles, comprising an insulating baffle fitted onto the utility pole, a large through hole in the middle of the insulating baffle, and a buckle device at the bottom for fixing the insulating baffle to the utility pole. The buckle device consists of two identical first clamps and second clamps, one end of which is rotatably connected by a rotating mechanism, and the other end of which is adjusted and fixed by a movable mechanism. A first through hole and a second through hole are respectively opened on the side of the first clamp near both ends, and a third through hole and a fourth through hole corresponding to the first and second through holes are opened on the side of the second clamp near both ends. A first connecting rod and a second connecting rod are respectively inserted through the first through hole, the third through hole, the second through hole, and the fourth through hole. Multiple connecting parts are fitted onto the first and second connecting rods, and the end of each connecting part is connected to the bottom surface of the insulating baffle, thereby enabling the buckle device to fix the insulating baffle to the utility pole for convenient power maintenance.

[0007] Preferably, the rotating mechanism consists of a rotating block and a pin. One end of the rotating block extends outward to form a hook, and the end of the second clamp is recessed to form a rotating groove. A pin is installed through the rotating groove, and the hook extends into the rotating groove and is sleeved on the pin, thereby realizing the movable connection between one end of the rotating block and the second clamp. The other end of the rotating block is fixedly connected to the end of the second clamp.

[0008] Preferably, the movable mechanism consists of a mounting base and a threaded long-headed bolt. The mounting base is embedded in a mounting groove corresponding to the end of the first clamp and is rotatably connected to the first clamp via a pin. A mounting groove is provided on the mounting base, and one end of the long-headed bolt is fixed in the mounting groove. The other end of the long-headed bolt passes through a placement groove corresponding to the second clamp and is partially exposed in the second clamp. An adjusting handle is installed in the exposed part, and a threaded fifth through hole is provided in the middle of the adjusting handle. By rotating the adjusting handle, the first clamp and the second clamp can be fixed and their relative positions adjusted.

[0009] Preferably, the connectors are in at least four sets, evenly distributed at both ends and the middle of the first and second connecting rods. Each connector consists of an inverted U-shaped clamping part and a T-shaped connecting part arranged vertically. The inverted U-shaped clamping part encloses the body of the first or second connecting rod, and a first bolt hole is provided on the side of the inverted U-shaped clamping part away from the connecting part. After the bolt is inserted into the first bolt hole, a washer and nut are installed for locking and fixing. The two ends of the side of the connecting part adjacent to the insulating baffle are provided with second bolt holes, and a small connecting through hole corresponding to the position of each second bolt hole is provided on the insulating baffle. After the bolt passes through each second bolt hole and the small connecting through hole in sequence, a washer and nut are installed for locking and fixing.

[0010] Preferably, a rangefinder is installed on the side of the second clamp near the adjusting handle to facilitate the installation of the insulating baffle on the pole.

[0011] Preferably, the insulating baffle consists of two identical first and second composite plates. U-shaped holes are provided on the inner sides of both the first and second composite plates. After installation, the first and second composite plates are tightly fitted together and partially overlap to ensure overall stability. The two U-shaped holes are combined to form a large circular or elliptical through-hole for easy assembly. Each connector of the first and second connecting rods near the second composite plate has a T-shaped connecting portion with a matching rubber pad on its top surface. This rubber pad eliminates the height difference between the first and second composite plates and improves the shock resistance of the insulating baffle.

[0012] Preferably, the insulating baffle, the first connecting rod, and the second connecting rod are all made of epoxy resin to ensure their insulation properties.

[0013] Preferably, the first connecting rod and the second connecting rod have an installation hole near the first clamp and the second clamp. A limiting pin is inserted through each installation hole. The angle between the limiting pin and the horizontal line is 15°, and the limiting pin is partially exposed on the first connecting rod and the second connecting rod to limit the first clamp and the second clamp.

[0015] The insulating baffle designed in this utility model consists of two identical assembled plates, which are easy to carry, assemble, and disassemble. During installation, the two plates are stacked one on top of the other (with a overlapping part in the middle), and then connected to a clamp via multiple connectors, a first connecting rod, a second connecting rod, and a clamp. The clamp is adjusted and locked via a movable mechanism, which fixes the two assembled insulating baffles to the pole, ensuring the overall stability after installation and thus truly providing safety protection for power maintenance personnel.

[0024] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-4 As shown, a special insulating baffle for utility poles includes an insulating baffle 1 fitted onto the utility pole. A large through hole 32 is formed in the middle of the insulating baffle 1. The insulating baffle 1 is fixed to the utility pole by a buckle device at its bottom. The buckle device consists of two identical first clamps 2 and second clamps 3. One end of the first clamp 2 and the second clamp 3 are rotatably connected by a rotating mechanism, and the other end is adjusted and fixed by a movable mechanism. A first through hole 4 and a second through hole 5 are formed on the sides of the first clamp 2 near both ends. A third through hole 6 and a fourth through hole 7, corresponding to the first through hole 4 and the second through hole 5, are formed on the sides of the second clamp 3 near both ends. A first connecting rod 8 and a second connecting rod 9 are respectively inserted through the first through hole 4, the third through hole 6, the second through hole 5, and the fourth through hole 7. Multiple connecting pieces 10 are fitted onto the rods of the first connecting rod 8 and the second connecting rod 9. The end of each connecting piece 10 is connected to the bottom surface of the insulating baffle 1, thereby enabling the buckle device to fix the insulating baffle 1 onto the utility pole for convenient power maintenance.

[0027] The rotating mechanism consists of a rotating block 11 and a pin 12. One end of the rotating block 11 extends outward to form a hook 40, and the end of the second clamp 3 is recessed to form a rotating groove 13. The pin 12 is installed through the rotating groove 13. The hook extends into the rotating groove 13 and is sleeved on the pin 12, so as to realize the movable connection between one end of the rotating block 11 and the second clamp 3. The other end of the rotating block 11 is fixedly connected to the end of the second clamp 3. The movable mechanism consists of a mounting base 14 and a threaded long-headed bolt 15. The mounting base 14 is embedded in the mounting groove 16 corresponding to the end of the first clamp 2 and is rotatably connected to the first clamp 2 by a pin. A mounting groove 17 is provided on the mounting base 14, and one end of the long-headed bolt 15 is fixed in the mounting groove 17. The other end of the long-headed bolt 15 passes through the placement groove 18 corresponding to the second clamp 3 and is partially exposed in the second clamp 3. An adjusting handle 19 is installed in the exposed part. A threaded fifth through hole 20 is provided in the middle of the adjusting handle 19. By rotating the adjusting handle 19, the first clamp 2 and the second clamp 3 can be fixed and their relative positions adjusted.

[0028] The connectors consist of at least four sets, evenly distributed at both ends and the middle of the first connecting rod 8 and the second connecting rod 9. Each connector 10 consists of an inverted U-shaped clamping part 21 and a T-shaped connecting part 22 arranged vertically. The inverted U-shaped clamping part 21 encloses the body of the first connecting rod 8 or the second connecting rod 9, and a first bolt hole 23 is provided on the side of the inverted U-shaped clamping part 21 away from the connecting part. After the bolt is inserted into the first bolt hole, a washer and a nut are installed for locking and fixing. The two ends of the side of the connecting part 22 adjacent to the insulating baffle 1 are provided with second bolt holes 24, and a small connecting through hole 25 corresponding to the position of each second bolt hole 24 is provided on the insulating baffle 1. After the bolt passes through each second bolt hole 24 and the small connecting through hole 25 in sequence, a washer 26 and a nut 27 are installed for locking and fixing.

[0029] The connector in this invention consists of an inverted U-shaped clamping part and a T-shaped connecting part, which facilitates the overall assembly and installation, and ensures the overall stability after installation. Furthermore, there are at least four sets of connectors, which can effectively ensure multi-point connection between the clamp and the insulating baffle, thereby ensuring the overall firmness after installation.

[0030] like Figure 5 As shown, a rangefinder 28 is installed on the side of the second clamp 3 near the adjusting handle 19 to conveniently display the height position of the insulating baffle, thereby facilitating its installation on the pole.

[0031] The insulating baffle 1 consists of two identical first and second composite plates 41 and 42. U-shaped holes 33 are provided on the inner sides of both the first and second composite plates 41 and 42. After installation, the first and second composite plates 41 and 42 are tightly fitted together and partially overlap (the two composite plates have a height difference, and the gap at the overlap is controllable, facilitating overall assembly). This ensures the overall stability after installation. The two U-shaped holes 33 are combined to form a large circular or elliptical through-hole 32 for easy assembly. Each connecting member 10 of the first connecting rod 8 and the second connecting rod 9 near the second composite plate 42 has a T-shaped connecting portion 22 with a matching rubber pad 29 on its top surface. The rubber pad 29 eliminates the height difference between the first and second composite plates 41 and 42 and improves the shock resistance of the insulating baffle 1. Corresponding through holes are provided on the rubber pads for easy overall installation. The insulating baffle 1, the first connecting rod 8, and the second connecting rod 9 are all made of epoxy resin to ensure their insulation.

[0032] like Figure 6-8As shown, the first connecting rod 8 and the second connecting rod 9 have a mounting hole 30 near the first clamp 2 and the second clamp 3. A limiting pin 31 is inserted through each mounting hole 30. The inclination angle between the limiting pin 31 and the horizontal line is preferably 15°. The limiting pin 31 is partially exposed on the first connecting rod 8 and the second connecting rod 9. It serves to limit the first clamp 2 and the second clamp 3 and also facilitates the assembly of the first and second composite plates, thereby improving the overall assembly efficiency.

[0033] The insulating baffle designed in this utility model consists of two identical assembled plates, which are easy to carry, assemble, and disassemble. During installation, the two plates are stacked one on top of the other (with an overlapping section in the middle), and then connected to a clamp via multiple connectors, a first connecting rod, a second connecting rod, and a clamp. The clamp is adjusted and locked via a movable mechanism, thus fixing the two assembled insulating baffles to the pole. The rubber pads eliminate the height difference between the two assembled plates and improve the shock resistance of the insulating baffles, ensuring the overall stability after installation and thus truly providing safety protection for power maintenance personnel.
