Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge with self-heating function. Background Art

[0002] At present, in order to ensure the aesthetics of cable layout in urban buildings, cable bridges are usually installed on the ceilings of corridors where cables are densely distributed. The cable bridge can cover the cables inside to protect and increase the appearance. When the current passes through the cables, a part of the electrical energy is consumed and dissipated in the form of heat. The existing cable bridge concentrates the cables together, which is not conducive to the heat dissipation of the cables. Especially under high temperature conditions, if the cables cannot dissipate heat quickly, the cable insulation layer will age quickly, reducing the service life of the cables, and even causing fires in severe cases.

[0003] For example, a Chinese patent (publication number: CN215071435U) discloses a self-heating cable tray, which relates to the technical field of cable trays. The self-heating cable tray comprises a cable tray main body, a heat dissipation mechanism is arranged on the outside of the cable tray main body, and a wire management mechanism is arranged on the inside of the cable tray main body. The self-heating cable tray has a vacuum insulation panel on the roof of the cable tray main body to isolate most of the heat transmitted from the roof, reduce the influence of the external temperature on the inside of the cable tray main body, and also has a dust-proof effect, reduces the accumulation of dust inside the cable tray main body, and ensures that the cables are neat and clean. The exhaust fan discharges the heat inside the cable tray main body to the outside, which has a heat dissipation effect, provides protection for the safety and stability of the cables inside the cable tray main body, and facilitates the operator to organize the cables inside the cable tray main body to avoid the entanglement of the cables that affects the subsequent maintenance work.

[0004] The above-mentioned cable tray with self-heating still has certain shortcomings. When the exhaust fan is controlled to start, the exhaust fan sends the heat inside the cable tray body to the outside to force the heat dissipation. The heat dissipation holes on the cable tray body also have a heat dissipation effect. When the cables need to be inspected, the two sets of wire management rings that are attracted to each other are separated and the cables are pulled out. However, during use, since the fan is far away from the wire management rings on the left and right sides and the distance between each wire management ring is close, it is difficult to adjust the position, resulting in the inability to effectively dissipate the heat of the cables only by the fan, thereby affecting the heat dissipation effect of the cables and reducing the service life of the cables. Therefore, a cable tray with self-heating is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 In this embodiment, a cable tray with self-heating includes a base plate 1, which is U-shaped. Support seats are fixed around the lower surface of the base plate 1. A shell 2 is installed on the upper surface of the base plate 1. A fixing plate 4 is fixed to the inner wall of the shell 2. An adjusting mechanism 5 is provided on the upper surface of the fixing plate 4 for adjusting the position of the cable and improving the heat dissipation effect. A heat dissipation mechanism 3 is provided inside the shell 2 for dissipating the heat of the cable.

[0024] See also Figure 3In order to adjust the position of the cable, the adjustment mechanism 5 in this embodiment includes a motor 501 fixed to the upper surface of the fixed plate 4, and the output shaft of the motor 501 is fixed with a first rotating rod 502. The adjustment mechanism 5 also includes a second rotating rod 504 rotatably connected to the upper surface of the inner cavity of the shell 2 through a bearing seat. The outer surfaces of the first rotating rod 502 and the second rotating rod 504 are provided with a transmission assembly 503. The first rotating rod 502 drives the second rotating rod 504 to rotate through the transmission assembly 503. A threaded rod 505 is fixed to the lower surface of the second rotating rod 504. The second rotating rod 504 rotates to drive the threaded rod 505 to rotate together. The outer surface of the threaded rod 505 is threadedly connected with two moving plates 506. The threaded rod 505 rotates to drive the two moving plates 506 to move relative to each other or opposite to each other at the same time. A plurality of partitions 507 are fixed to the upper surface of the moving plate 506 for separating the cables to prevent the cables from being close to each other and affecting heat dissipation.

[0025] Among them, the transmission assembly 503 includes a first sprocket fixed to the outer surface of the first rotating rod 502 and a second sprocket fixed to the outer surface of the second rotating rod 504. The outer surfaces of the first sprocket and the second sprocket are connected by chains, and the first rotating rod 502 drives the second rotating rod 504 to rotate through the transmission assembly 503.

[0026] In addition, a rotating hole is opened on the upper surface of the fixed plate 4, and the second rotating rod 504 is rotatably connected to the inside of the rotating hole through a bearing, thereby increasing the stability of the second rotating rod 504 during rotation. The thread of the threaded rod 505 is divided into two sections, and the two sections of the thread are in opposite directions. By rotating the threaded rod 505, the two movable plates 506 are driven to move relative to each other or opposite to each other at the same time.

[0027] In addition, two sliding rods are fixed to the lower surface of the fixed plate 4, and the movable plate 506 is slidably connected to the outer surfaces of the sliding rods, thereby increasing the stability of the movable plate 506 when moving and preventing the movable plate 506 from rotating with the threaded rod 505.

[0028] In the adjustment mechanism 5 of this embodiment, the motor 501 drives the first rotating rod 502 to rotate, and the first rotating rod 502 drives the second rotating rod 504 and the threaded rod 505 to rotate together through the transmission assembly 503, so that the two movable plates 506 move to the appropriate positions at the same time, and the cables are placed on the movable plates 506 so that each cable is located between the two partitions 507, which is convenient for controlling the positions of the cables at the upper and lower ends and is beneficial to heat dissipation.

[0029] See also Figure 4In order to dissipate the heat of the cable, the heat dissipation mechanism 3 in this embodiment includes a plurality of fans 303 fixed on the left and right sides of the inner cavity of the shell 2 and a plurality of first filters 302 fixed on the left and right sides of the shell 2. The fans 303 are used to blow air to dissipate the heat of the cable, and the first filters 302 are used to prevent dust from entering the interior of the shell 2. The heat dissipation mechanism 3 also includes an air outlet 304 opened on the upper surface of the bottom plate 1 and a plurality of through holes 301 opened on the left and right sides of the inner cavity of the shell 2. The through holes 301 facilitate air to enter the interior of the shell 2, and the air outlet 304 is used to discharge the hot air. The heat dissipation mechanism 3 also includes a second filter 305 fixed on the lower surface of the bottom plate 1 to prevent dust from entering the interior of the shell 2.

[0030] The first filter 302 corresponds to the through hole 301, so that air can enter the interior of the housing 2 through the through hole 301. The fan 303 corresponds to the through hole 301, so that the fan 303 can blow air toward the cable to dissipate heat from the cable.

[0031] In addition, the fans 303 are evenly distributed, so that the fans 303 can evenly dissipate heat from the cables, thereby improving the heat dissipation effect. The air outlets 304 are located above the second filter 305 to prevent dust from entering the interior of the housing 2 through the air outlets 304 .

[0032] In the heat dissipation mechanism 3 of this embodiment, the fan 303 sucks external air into the through hole 301 through the first filter 302. The air is blown toward the cable by the fan 303 to dissipate heat from the cable. The used air drives the heat to be discharged through the air outlet 304 and the second filter 305, which is convenient for heat dissipation and ventilation of the cable.

[0033] The working principle of the above embodiment is:

[0034] (1) Start the motor 501. The motor 501 drives the first rotating rod 502 to rotate. The first rotating rod 502 drives the first sprocket to rotate. The first sprocket drives the second sprocket and the second rotating rod 504 to rotate together through the chain. The threaded rod 505 is driven to rotate together through the second rotating rod 504. Since the two threads of the threaded rod 505 are in opposite directions, when the threaded rod 505 rotates, it will drive the two moving plates 506 to move to the appropriate positions at the same time, and the moving plates 506 will slide on the outer surface of the sliding rod, thereby increasing the stability of the moving plates 506 when moving. At this time, the cables are placed on the upper surface of the moving plates 506 so that each cable is located between the two partitions 507, which is convenient for controlling the positions of the cables at the upper and lower ends and is beneficial for heat dissipation.

[0035] (2) Start the fan 303. The fan 303 draws external air into the through hole 301 through the first filter 302. The first filter 302 blocks the dust in the air. The air entering the through hole 301 is blown toward the cable by the fan 303 to dissipate heat from the cable. The used air drives the heat to be discharged through the air outlet 304 and the second filter 305, which facilitates the heat dissipation of the cable.
