Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable bridge, and particularly relates to a cable bridge for smart grid wiring. BACKGROUND

[0002] As a key supporting structure for cable laying in the power system, the cable bridge is widely used in the fields of buildings, industrial facilities and smart grids. The traditional suspension type cable bridge mainly includes groove type, tray type and ladder type, and the basic structure thereof is usually composed of metal supports, supporting arms and matching installation accessories, and the surface thereof is usually coated with zinc or sprayed with paint to improve the corrosion resistance. However, with the rapid development of smart grids, the power load density is significantly increased, the cable layout is complicated, and the operation environment is often accompanied by high-frequency vibration and temperature rise challenges. The traditional bridge has the following defects.

[0003] Insufficient heat dissipation performance: the existing bridge mainly relies on natural convection or simple ventilation holes for heat dissipation, and the heat dissipation efficiency is restricted by environmental conditions, which easily leads to accelerated aging of the cable insulation layer and even causes short circuit risk;

[0004] Poor adaptability of the clamping mechanism: the traditional clamping structure mainly adopts fixed binding or bolt locking design, and cannot dynamically adjust the clamping force according to the diameter difference of the cable (such as 10-50mm). In actual application, over-tight clamping easily causes damage to the cable skin, and over-loose clamping leads to cable displacement or falling, especially in the vibration environment, the failure rate is significantly increased;

[0005] Low efficiency of the damping system: the traditional bridge often uses a single spring damper, and the natural frequency thereof is easy to resonate with the vibration frequency of the power grid equipment, which leads to increased friction between the cable and the bridge;

[0006] Therefore, it is necessary to design a cable bridge for smart grid wiring to solve the above problems. SUMMARY

[0052] As known from the above description, the application has the following beneficial effects: the clamping mechanism 4 is installed through the support beam 12 during use, the cable is assisted to be supported through the mounting clamping frame 15 and the support base 13, the installation is separated during installation and use, ventilation and heat dissipation are guaranteed, and the clamping arm 44 is rotated through the clamping pressing column 43, so that the clamping arm 44 is clamped on the cable and the clamping claw 45 is clamped on the cable to guarantee stability.

[0053] Example two: please refer to Figures 1 to 10As shown, on the basis of embodiment one, the present application provides a technical solution: the heat dissipation mechanism 2 includes an insulating plate 22 installed on the hoisting main frame 11 and a supporting seat 13 and a supporting plate 25 installed on the supporting seat 13, the upper side of the supporting plate 25 is provided with a heat dissipation silica gel pad 21, one side of the insulating plate 22 is provided with a heat dissipation pipe 23 and a heat dissipation fin 24, one side of the heat dissipation fin 24 is installed on the surface of the heat dissipation pipe 23, one end of the heat dissipation pipe 23 is communicated with one end of the heat dissipation silica gel pad 21, in use, the heat dissipation silica gel pad 21 is installed on the supporting plate 25, and one end of the heat dissipation silica gel pad 21 is connected to the on-off head 28 and the circulating pump 29 through the connecting pipe 26 and the connecting head 27; one end of the heat dissipation silica gel pad 21 is provided with the connecting pipe 26, one end of the connecting pipe 26 is provided with the connecting head 27, one end of the heat dissipation pipe 23 is installed with the circulating pump 29 through the on-off head 28, and the circulating pump 29 is connected with the connecting pipe 26 through the on-off head 28 and the connecting head 27, the upper surface of the heat dissipation silica gel pad 21 is arc-shaped, and the heat dissipation silica gel pad 21 is filled with heat-conducting silicon oil in the inside, the heat dissipation pipes 23 are communicated with each other, and the silicon oil is circulated between the heat dissipation silica gel pad 21 and the heat dissipation pipe 23 through the operation of the circulating pump 29, so that the heat absorption and dissipation are facilitated, and the heat dissipation fin 24 is used to speed up the heat dissipation to the outside.

[0054] The arc-shaped design of the heat dissipation silica gel pad 21 generates a radial pressure through elastic deformation when wrapping the cable, which is complementary to the clamping force of the clamping jaw 45. When the cable expands due to heat, the degree of softening of the silica gel pad matches the V-shaped angle (50-70°) of the clamping jaw, so that the clamping force remains in dynamic balance. At the same time, the heat-conducting silicon oil circulation system transmits part of the heat to the clamping seat 41 area through the spiral layout of the heat dissipation pipe 23, adjusts the pre-tightening force of the return spring 42 by using the thermal expansion and contraction effect, and realizes temperature self-compensation clamping. The separate installation of the clamping mechanism forms equidistant air ducts between the cables, and forms vertical convection with the ventilation holes of the main frame cover plate 14, so that the air flow rate is improved, and the heat dissipation efficiency of the heat dissipation fin 24 is improved. The hollow structure of the supporting cross beam 12 serves as an auxiliary air duct, and the opening direction forms a flow guide angle with the limiting plate of the clamping arm 44, guiding the airflow to pass through the cable dense area.

[0055] The heat dissipation mechanism 2 adopting the above technical solution supports the heat dissipation silica gel pad 21 through the supporting seat 13 and the supporting plate 25 in use, supports the cable through the heat dissipation silica gel pad 21 on the supporting plate 25, and wraps the cable with the heat dissipation silica gel pad 21. The heat of the cable is absorbed by the heat dissipation silica gel pad 21 and the built-in heat-conducting medium, the heat-conducting medium is circulated between the heat dissipation pipe 23 and the heat dissipation silica gel pad 21 through the operation of the circulating pump 29, so that the heat of the cable is quickly conducted and dissipated. A three-level active heat dissipation system of contact, conduction and convection is adopted, more than 70% of the heat is quickly conducted and taken away through the direct contact of the silica gel pad.

[0057] The involute type rotating guide groove 47 of the clamping arm 44 converts the longitudinal vibration of the suspension system into nonlinear rotary motion, and the vibration energy is consumed through the friction between the anti-skid lines of the clamping claw 45 and the cable surface; the self-winding friction damping of the suspension cable 38 and the return spring 42 of the clamping mechanism form a parallel damping system; when the bridge frame is subjected to a transverse force, the displacement of the buffer rod 36 pushes the damping ball 3981 through the guide push plate 396, and the reverse force is transmitted to the cable through the clamping pressure column 43, forming a force closed loop balance system, and the V-shaped design of the clamping mechanism produces a self-tightening effect in the vibration environment, and the greater the vibration amplitude, the greater the clamping force.
