Abstract
Description
Technical Field
[0001] This utility model relates to the field of power facility technology, and in particular to a cable spacer anti-detachment locking device. Background Technology
[0002] With rapid social development, electricity demand has experienced explosive growth. Urban construction continues, with skyscrapers springing up everywhere. Various large commercial complexes and residential communities place extremely high demands on the stability and reliability of power supply. Industrial production continues to expand, and the efficient operation of many factories cannot be separated from stable power support. Against this backdrop, power transmission networks are becoming increasingly complex and vast. As the main transmission carrier, cables are being laid across an ever-expanding area. In some harsh environments, cables face even more severe challenges. Once a cable spacer falls off, it can cause a serious accident involving a short circuit between cable phases, resulting in large-scale power outages and causing huge losses to social production and life.
[0003] Cable spacers are crucial components in power transmission used to maintain a specific distance between cables. Their function is to prevent damage to the insulation layer caused by cable contact or collision, thereby ensuring the stability and safety of power transmission. Current cable spacers use simple clamps and hooks to fix cables. This fixing method has limited stability. When the cable is subjected to external vibration or wind force, the hooks are prone to loosening, causing the spacer to fall off. This can lead to cable squeezing and friction damage, resulting in short circuits and leakage. It can also disrupt the uniform distribution of the electric field, causing insulation breakdown, voltage fluctuations, increased maintenance costs and power outage time, and adversely affecting production and daily life. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a cable spacer anti-detachment locking device, which aims to improve the problem that the existing cable spacer fixing methods have limited stability and are prone to causing the spacers to fall off.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable spacer anti-detachment locking device, comprising a bracket, a fixed column fixedly connected between two adjacent brackets, a support rod rotatably connected to the outer wall of the fixed column, a sleeve rotatably connected to the other end of the support rod, a clamping bolt provided in the middle of the sleeve, the other end of the clamping bolt penetrating the outer wall of the support rod and threadedly connected to a nut, a pin bolt provided at the top of the support rod, the lower end of the pin bolt penetrating the support rod and the outer wall of the sleeve and threadedly connected to a nut, and a shock-absorbing mechanism provided on the inner wall of the bracket for damping vibration.
[0006] As a further description of the above technical solution:
[0007] The shock absorption mechanism includes a fixed pile, both ends of which are fixedly connected to the inner wall of the support. A sleeve is rotatably connected to the outer wall of the fixed pile, and a sleeve is slidably connected to the outer wall of the sleeve. The other end of the sleeve is rotatably connected to the outer wall of the support rod through a U-shaped block. A threaded groove is provided on the outer wall of the sleeve, and an adjusting ring is threadedly connected to the outer wall of the threaded groove. A spring is provided between the adjusting ring and the adjacent sleeve.
[0008] As a further description of the above technical solution:
[0009] Multiple support blocks are fixedly connected between adjacent brackets, and a wind speed monitor is fixedly connected to the outer wall of each support block.
[0010] As a further description of the above technical solution:
[0011] The outer wall of the bracket has weight-reducing holes, and a nameplate is fixedly connected to the outer wall of the bracket.
[0012] As a further description of the above technical solution:
[0013] As a further description of the above technical solution:
[0014] The support rod and the outer wall of the casing are both fixedly connected to a fixing ring, and an auxiliary rope is provided between two adjacent fixing rings.
[0015] As a further description of the above technical solution:
[0016] Each of the support rods and the adjacent sides of the casing is fixedly connected to a rubber pad, and the outer wall of the rubber pad is provided with a contact ball.
[0017] As a further description of the above technical solution:
[0018] The outer wall of the first nut is provided with a fastening nut, which is arranged in the opposite direction to the first nut.
[0019] As a further description of the above technical solution:
[0020] The strut array is provided, and a warning light is provided on the outer wall of the bracket.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the cable is placed between the support rod and the housing, and the clamping bolt is rotated to clamp the cable. The rubber pad tightly holds the cable in place. The rubber pad on the contact ball increases the contact area with the cable surface and plays an auxiliary buffering role when the cable vibrates, improving the shock absorption performance. After the clamping bolt is locked, the fastening nut is tightened in the opposite direction to make the first nut less likely to loosen. Then, the pin bolt is passed through the reserved hole and the second nut is tightened. The auxiliary rope between the two fixing rings shares the pressure at the hinge of the support rod and the housing, greatly enhancing the mechanical strength. Through multi-directional fixing, the cable is firmly clamped and is not easy to loosen or fall off.
[0023] 2. In this utility model, the support rod and the bracket are rotatably connected by a fixed column, which allows for rotation and provides a certain amount of room for movement. When encountering strong winds and severe weather, and the cable shakes and vibrates violently, the support rod swings, causing the sleeve to slide inside the sleeve. The spring absorbs the vibration energy, thereby effectively reducing the vibration amplitude of the cable, reducing potential risks, extending the service life of the cable, reducing the vibration transmission to surrounding facilities, protecting the structural integrity of the facilities, and reducing maintenance costs.
