Description

Technical Field

[0001] This invention relates to a fire-resistant busbar trunking, and more particularly to a fire-resistant busbar trunking that is easy to connect and install. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute a large amount of power to various components of a distributed system. Fire-resistant busbar trunking consists of a shell coated with fire-retardant paint, busbars wrapped with fire-resistant mica tape, and supports made of fire-resistant insulating materials. It is suitable for high-rise buildings and important facilities, replacing fire-resistant cables for power transmission and distribution.

[0003] Patent application CN212462726U, authorized and published on 20210202, discloses an easy-to-install fire-resistant busbar trunking, including a busbar trunking body and a fixing plate. The outer side of the busbar trunking body has an external sliding groove, and a connecting sleeve is connected to the rear of the external sliding groove. The fixing plate is connected to the front of the external sliding groove, and a fixing plate connecting bolt is provided on the upper part of the fixing plate. A connecting block is connected to the inner side of the fixing plate, and a small threaded hole is provided on the side of the connecting block. A large threaded hole is provided on the upper part of the connecting block, and a first fixing frame is connected to the upper side of the connecting block. A threaded head is provided at the lower end of the first fixing frame, and a fixing nut is placed on the outer side of the threaded head. A wire harness groove is provided on the inner side of the busbar trunking body, and a cover plate is connected to the bottom of the busbar trunking body. A cover plate connecting groove is provided at the upper end of the cover plate, and a heat dissipation mesh is placed in the middle of the cover plate. This easy-to-install fire-resistant busbar trunking features a combined first fixing frame, facilitating the connection and installation of the busbar trunking. While the aforementioned patents facilitate the installation of busbar trunking, they require complete disassembly for maintenance, a process that is quite cumbersome.

[0004] Therefore, in view of the fact that the busbar trunking needs to be completely disassembled during maintenance, which is a troublesome process, a fire-resistant busbar trunking that is easy to maintain and easy to connect and install is provided. Summary of the Invention

[0005] To overcome the drawback that most existing fire-resistant busbar trunking systems require complete disassembly for maintenance, which is cumbersome, the present invention aims to provide a fire-resistant busbar trunking system that is easy to maintain and install.

[0006] This invention is achieved through the following technical means:

[0007] A fire-resistant busbar trunking that is easy to connect and install includes a mounting plate, a first fixing frame, and a busbar trunking. The first fixing frame is symmetrically connected to the front and rear sides of the bottom of the mounting plate. The busbar trunking is installed between the lower parts of the first fixing frames. The trunking also includes a limit frame, a clamping rod, a clamping mechanism, and a heat insulation mechanism. The limit frame is symmetrically connected to the front and rear sides of the busbar trunking. The limit frame is slidably connected to a clamping rod for fixing the first fixing frame. The clamping rod contacts the adjacent first fixing frame. The clamping rod is provided with a clamping mechanism for clamping the clamping rod. The lower part of the busbar trunking is provided with a heat insulation mechanism for protecting the busbar.

[0008] To further explain, the clamping mechanism includes a first elastic element, a limiting rod, and a spring piece. The clamping rod is connected to the adjacent limiting frame by the first elastic element. The busbar trough is symmetrically and slidably connected to the limiting rod on both the front and rear sides. The limiting rod is located outside the limiting frame and contacts the adjacent first fixing frame. The limiting rod is connected to the busbar trough by a spring piece.

[0009] To further explain, the insulation mechanism includes a fixed base, a second fixed frame, and a water storage frame. Fixed bases are connected to both the left and right sides of the lower part of the busbar trunking, and a second fixed frame is connected between the fixed bases. A water storage frame is connected to the bottom of the second fixed frame.

[0010] Further explanation: It also includes a winding mechanism for pulling the lever. The winding mechanism includes a limit block, a rotating shaft, a winding wheel, and a pull rope. Limit blocks are connected to the middle of the front and rear sides of the upper part of the busbar groove. A rotating shaft is rotatably connected between the limit blocks. Two winding wheels are connected to the front and rear sides of the rotating shaft. Pull ropes are wound on the winding wheels. One end of the pull rope is connected to the adjacent winding wheel, and the other end of the pull rope is connected to the adjacent lever.

[0011] To further explain, it also includes a limiting mechanism for guiding purposes. The limiting mechanism includes a limiting frame and a sliding frame. The limiting frames are connected to the top left and right sides of the busbar trough. The limiting frames on the left and right sides are in contact with the first fixed frame on the left and right sides, respectively. The top of the limiting frame is connected to a sliding frame.

[0012] Further explanation: It also includes an anti-slip mechanism to slow down the downward movement of the busbar. The anti-slip mechanism includes a limit ring, a sliding rod, a second elastic element, and a rubber block. Two limit rings are symmetrically connected to the left and right sides of the top of the busbar. Four sliding rods are slidably connected to each limit ring. A rubber block is connected to each sliding rod. The rubber block contacts the adjacent first fixing frame. The second elastic element is connected between the rubber block and the adjacent limit ring.

[0013] To further explain, it also includes a dispersing mechanism for blowing away smoke. The dispersing mechanism includes a fixed frame and fans. The fixed frame is connected to the middle of the bottom of the busbar trunking, and eight fans are connected at intervals on the fixed frame.

[0014] To further explain, the second elastic element is a compression spring.

[0015] This invention provides a fire-resistant busbar trunking that is easy to connect and install, and has the following advantages:

[0016] 1. By pulling the lever inward, the lever can be separated from the first fixing frame, which makes it easier for people to disassemble the busbar trunking and thus facilitates the maintenance of the fire-resistant busbar trunking that is easy to connect and install.

[0017] 2. The present invention restores the original shape by the first elastic element, which can drive the locking rod to move outward and reset, so that the locking rod contacts the first fixing frame, thereby fixing the locking rod and preventing the locking rod from moving.

[0018] 3. Under the action of the limiting frame and the sliding frame, the present invention can guide the movement direction of the busbar trunking, thereby preventing the busbar trunking from deviating and making it easier for people to install the busbar trunking.

[0019] 4. By having the first fixing frame contact the rubber block, the present invention can increase the friction between the rubber block and the first fixing frame, thereby slowing down the downward movement speed of the busbar trough and preventing the busbar trough from suddenly falling.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings, and embodiments of the present invention will be given in conjunction with the accompanying drawings.

[0030] Example 1

[0031] A fire-resistant busbar trunking system that is easy to connect and install, see Figures 1-4 As shown, it includes a mounting plate 1, a first fixing frame 2, a busbar trough 3, a limiting frame 4, a clamping rod 5, a clamping mechanism 6, and a heat insulation mechanism 7. The mounting plate 1 is symmetrically connected to the first fixing frames 2 on both the front and rear sides of its bottom. The busbar trough 3 is installed between the lower parts of the four first fixing frames 2. The busbar trough 3 is symmetrically welded to the front and rear sides of its front and rear sides. The four limiting frames 4 are slidably connected to the clamping rods 5. The four clamping rods 5 contact the adjacent first fixing frames 2 respectively. The first fixing frames 2 can be fixed by clamping the clamping rods 5. The clamping mechanism 6 is provided on the clamping rods 5. The heat insulation mechanism 7 is provided at the lower part of the busbar trough 3.

[0032] See Figure 2 and Figure 3 As shown, the clamping mechanism 6 includes a first elastic element 61, a limiting rod 62, and a spring piece 63. The four clamping rods 5 are respectively connected to the adjacent limiting frame 4 by the first elastic element 61. Under the elastic force of the first elastic element 61, the clamping rods 5 can be fixed, thereby preventing the clamping rods 5 from moving. The busbar trough 3 is symmetrically connected to the limiting rods 62 on both the front and rear sides. The limiting rods 62 are located outside the limiting frame 4. The four limiting rods 62 are respectively in contact with the adjacent first fixing frame 2. The four limiting rods 62 are each connected to the busbar trough 3 by a spring piece 63.

[0033] See Figure 4 As shown, the heat insulation mechanism 7 includes a fixed base 71, a second fixed frame 72, and a water storage frame 73. Fixed bases 71 are welded to both the left and right sides of the lower part of the busbar trough 3. The second fixed frame 72 is connected between the two fixed bases 71. The bottom of the second fixed frame 72 is connected to the water storage frame 73. By adding an appropriate amount of clean water into the water storage frame 73, the hot air can be blocked, thereby preventing the hot air from drifting into the busbar trough 3.

[0034] In the initial state, because the first fixing bracket 2 abuts against the limiting rod 62, the spring piece 63 is in a deformed state. When people need to use the fire-resistant busbar trunking for easy connection and installation, firstly, pull the clamping rod 5 inward, stretch the first elastic element 61, and separate the clamping rod 5 from the first fixing bracket 2. Then, pull the mounting plate 1 upward to remove it. The mounting plate 1 drives the first fixing bracket 2 upward to remove it, separating the first fixing bracket 2 from the limiting rod 62. The spring piece 63 returns to its original shape, and the spring piece 63 drives the limiting rod 62 upward to contact the clamping rod 5, thereby locking the clamping rod 5 and preventing it from moving. Then, release the clamping rod 5, and then use bolts to fasten the mounting plate. 1. Install the first fixing frame 2 in the designated position, then pull the busbar trough 3 upward to make the first fixing frame 2 contact the limiting rod 62. The first fixing frame 2 squeezes the limiting rod 62 and moves downward. The spring piece 63 deforms, causing the limiting rod 62 to separate from the locking rod 5. The first elastic element 61 returns to its original shape and drives the locking rod 5 to move outward and reset, making the locking rod 5 contact the first fixing frame 2, thus fixing the first fixing frame 2 and preventing the busbar trough 3 from falling downward. Then, people can fix the busbar in the busbar trough 3. Then add an appropriate amount of clean water to the water storage frame 73 to isolate the hot air and prevent the hot air from drifting into the busbar trough 3, thereby cleaning the busbar. For protection, when insulation is not required, the water in the water storage frame 73 can be drained. When maintenance is needed on this fire-resistant busbar trough, which is easy to connect and install, first remove the busbar, then pull the busbar trough 3, and then pull the clamp rod 5 inward. The first elastic element 61 stretches, causing the clamp rod 5 to separate from the first fixing frame 2. Then slowly release the busbar trough 3. Under the action of gravity, the busbar trough 3 moves downward, causing the first fixing frame 2 to separate from the limiting rod 62. The spring piece 63 returns to its original shape, and the spring piece 63 drives the limiting rod 62 to move upward, so that the limiting rod 62 contacts the clamp rod 5, thereby fixing the clamp rod 5. Then release the clamp rod 5, and then remove the busbar trough 3. Then proceed with the maintenance of the busbar trough 3. Maintenance can be performed. After the busbar trough 3 is maintained, pull the busbar trough 3 upward to make the first fixing frame 2 contact the limiting rod 62. The first fixing frame 2 squeezes the limiting rod 62 and moves downward. The spring piece 63 deforms, causing the limiting rod 62 to separate from the locking rod 5. The first elastic element 61 returns to its original shape and drives the locking rod 5 to move outward and reset, so that the locking rod 5 contacts the first fixing frame 2, thereby fixing the first fixing frame 2 and preventing the busbar trough 3 from falling downward. Then the busbar is fixed in the busbar trough 3. When people no longer need to use the fire-resistant busbar trough that is easy to connect and install, the fire-resistant busbar trough that is easy to connect and install can be removed from the designated position.

[0035] Example 2

[0036] Based on Example 1, see Figure 1 and Figure 5 As shown, it also includes a winding mechanism 8, which includes a limit block 81, a rotating shaft 82, a winding wheel 83, and a pull rope 84. Limit blocks 81 are welded to the middle of the front and rear sides of the upper part of the busbar groove 3. A rotating shaft 82 is rotatably connected between the two limit blocks 81. Two winding wheels 83 are connected to the front and rear sides of the rotating shaft 82. A pull rope 84 is wound on each of the four winding wheels 83. One end of the pull rope 84 is connected to the adjacent winding wheel 83, and the other end of the pull rope 84 is connected to the adjacent clamping rod 5. By winding the pull rope 84 through the winding wheel 83, the pull rope 84 can pull the clamping rod 5 to move inward.

[0037] When people need to pull the lever 5 to move inward, they can pull the winding wheel 83 on one side to rotate. The winding wheel 83 on one side drives the winding wheel 83 on the other side to rotate together through the rotating shaft 82, so that the winding wheel 83 winds up the pull rope 84. The winding wheel 83 pulls the four levers 5 to move inward at the same time through the pull rope 84, so that people can easily pull the levers 5 to move inward. When the lever 5 moves outward to reset, the lever 5 pulls the winding wheel 83 and the rotating shaft 82 to reverse and reset through the pull rope 84, so that the winding wheel 83 releases the pull rope 84.

[0038] See Figure 1 and Figure 6 As shown, it also includes a limiting mechanism 9, which includes a limiting frame 91 and a sliding frame 92. The limiting frames 91 are welded to the top left and right sides of the busbar trough 3. The limiting frames 91 on the left and right sides are in contact with the first fixing frame 2 on the left and right sides respectively. The top of the two limiting frames 91 are connected to the sliding frame 92. Under the action of the limiting frame 91 and the sliding frame 92, the movement direction of the busbar trough 3 can be guided.

[0039] When the first fixed frame 2 moves upward and is removed, it separates from the limiting frame 91 and the sliding frame 92. When the busbar trough 3 moves upward, it drives the limiting frame 91 and the sliding frame 92 to move upward, so that the limiting frame 91 and the sliding frame 92 come into contact with the first fixed frame 2. The limiting frame 91 and the sliding frame 92 guide the movement direction of the busbar trough 3, thereby preventing the busbar trough 3 from deviating, and making it convenient for people to install the busbar trough 3 on the first fixed frame 2. When the busbar trough 3 moves downward, it drives the limiting frame 91 and the sliding frame 92 to move downward, and the limiting frame 91 and the sliding frame 92 separate from the first fixed frame 2.

[0040] See Figure 1 and Figure 7As shown, it also includes an anti-slip mechanism 10, which includes a limit ring 101, a sliding rod 102, a second elastic element 103, and rubber blocks 104. Two limit rings 101 are symmetrically welded to the left and right sides of the top of the busbar trough 3. Four sliding rods 102 are slidably connected to each of the eight limit rings 101. Rubber blocks 104 are connected to each of the thirty-two sliding rods 102. The thirty-two rubber blocks 104 are in contact with the adjacent first fixed frame 2. Under the action of the rubber blocks 104, the friction between the rubber blocks 104 and the first fixed frame 2 can be increased, thereby slowing down the downward movement speed of the busbar trough 3. A second elastic element 103 is connected between each of the thirty-two rubber blocks 104 and the adjacent limit ring 101. The second elastic element 103 is a compression spring.

[0041] Initially, because the first fixing frame 2 presses against the rubber block 104, the second elastic element 103 is compressed. When people need to pull the first fixing frame 2 upward to remove it, they first pull the sliding rod 102 outward. The sliding rod 102 drives the rubber block 104 outward, compressing the second elastic element 103 and separating the rubber block 104 from the first fixing frame 2. Then, people can pull the first fixing frame 2 upward to remove it. After the first fixing frame 2 is removed, the sliding rod 102 is released, and the second elastic element 103 returns to its original state. The second elastic element 103 drives the rubber block 104 and the sliding rod 102 inward. When the busbar trough 3 moves upward, the busbar trough 3 drives the limiting ring 10. 1. Moving upwards, when the first fixed frame 2 contacts the rubber block 104, the first fixed frame 2 squeezes the rubber block 104 to move outwards, the second elastic element 103 is compressed, and the rubber block 104 drives the sliding rod 102 to move outwards. Under the elastic force of the second elastic element 103, the rubber block 104 clamps the first fixed frame 2. When the busbar trough 3 moves downwards, the rubber block 104 increases the friction between itself and the first fixed frame 2, thereby slowing down the downward movement of the busbar trough 3 and preventing the busbar trough 3 from suddenly falling. When the first fixed frame 2 separates from the rubber block 104, the second elastic element 103 returns to its original state, and the second elastic element 103 drives the rubber block 104 and the sliding rod 102 to move inwards.

[0042] See Figure 1 and Figure 8 As shown, it also includes a dispersing mechanism 11, which includes a fixed frame 111 and a fan 112. The fixed frame 111 is connected to the bottom center of the busbar 3, and eight fans 112 are bolted to the fixed frame 111 at intervals. By turning on the fans 112, the smoke can be blown to the surroundings.

[0043] In the event of a fire, fan 112 can be turned on to blow the smoke outwards, thus preventing the smoke from adhering to the fire-resistant busbar trunking that is easy to connect and install. When it is no longer necessary to blow away the smoke, fan 112 can be turned off.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
