Description

Technical Field

[0001] This utility model relates to the field of fire-resistant busbar technology, and in particular to a novel fire-resistant busbar. Background Technology

[0002] Fire-resistant busbar trunking is a special power transmission equipment that can continuously supply power under extreme conditions such as fire. Its outer shell is mostly made of cold-rolled thin steel plate, the copper conductor of the busbar is often wound with polyesterimide and high-temperature resistant mica tape, and the support is made of fire-resistant and insulating materials such as alumina high-temperature ceramic parts. It is widely used in high-rise buildings, industrial manufacturing, transportation, data centers and other fields.

[0003] Most current fire-resistant busbar trunking shells are one-piece structures without inspection ports. This means that when maintaining the busbar trunking, it is necessary to remove the fixing bolts of the entire shell, and sometimes even disconnect part of the power supply to disassemble it, which is time-consuming and affects work efficiency. In addition, after disassembly, it needs to be reinstalled and sealed. During the installation process, improper operation can easily lead to seal failure. Therefore, this application proposes a new type of fire-resistant busbar trunking to meet the requirements. Utility Model Content

[0004] In order to overcome the shortcomings of low maintenance efficiency and easy sealing failure due to improper operation in the existing technology, this utility model provides a new type of fire-resistant busbar trunking.

[0005] The technical implementation scheme of this utility model is as follows: a novel fire-resistant busbar trunking includes a busbar trunking body, an inspection port is provided on one side of the busbar trunking body, an inspection door with a size adapted to the inspection port is provided inside the inspection port, a hinge is installed at the connection between the inspection door and the busbar trunking body on one side of the inspection door, a sealing component is provided at the connection between the inspection door and the inspection port, and an opening and closing component is provided at the connection between the side of the inspection door away from the hinge and the busbar trunking body.

[0006] Optionally, the sealing assembly includes a sealing groove, a mounting groove, and a sealing ring. The sealing groove is formed on the inner wall of the access port, the mounting groove is formed in the middle of the four sides of the access door, and the sealing ring is installed inside the mounting groove. The sealing ring is made of rubber and is hollow inside.

[0007] Optionally, the sealing assembly further includes an air chamber, a piston, and a connecting hole. The air chamber is located inside the access door, the piston is slidably connected to the air chamber and is sized to match it, and the connecting hole is located on the inner wall of the bottom of the air chamber and communicates with the sealing ring.

[0008] Optionally, the sealing assembly further includes a first groove, a first slider, a first spring, and a connecting rod. The first groove is formed on the outer surface of the access door and its bottom is connected to the top of the air chamber. The first slider is slidably connected to the first groove. The first spring is installed inside the first groove and its two ends are respectively fixedly connected to the top of the first slider and the inner wall of the top of the first groove. The connecting rod is movably connected to the air chamber and the first groove and its two ends are respectively fixedly connected to the bottom of the first slider and the top of the piston.

[0009] Optionally, the opening and closing assembly includes an upper mounting base, a lower mounting base, a mounting block, a mounting hole, a through slot, and a mounting rod. The upper and lower mounting bases are both fixedly connected to the busbar trunking body and located on the side of the access door away from the hinge. The mounting block is fixedly connected to the side of the access door away from the hinge and is adapted to the spacing between the upper and lower mounting bases. The mounting hole passes through the mounting block, the through slot passes through the upper mounting base, and the mounting rod is movably connected to the through slot and is adapted to the size of the mounting hole.

[0010] Optionally, the opening and closing assembly further includes a second slide groove, a second slider, a second spring, and a pull block. The second slide groove is formed in the inner wall of the through groove. The second slider is fixedly connected to the outer periphery of the mounting rod and slidably connected to the second slide groove. The second spring is sleeved on the outer periphery of the mounting rod and its two ends are respectively fixedly connected to the top of the second slider and the inner wall of the top of the second slide groove. The pull block is fixedly connected to the top of the mounting rod.

[0011] This utility model has the following advantages:

[0012] 1. This utility model incorporates a sealing assembly. A first slider slides upwards along a first groove, compressing a first spring. During this process, a connecting rod drives a piston upwards along the air chamber, drawing air from the sealing ring into the air chamber through a connecting hole. When the sealing ring deflates and moves out of the sealing groove, the access door can be opened by rotating the hinge, allowing maintenance to begin. After maintenance, the access door is rotated in the opposite direction until it is submerged in the access opening. The first slider is released, and the first spring rebounds, driving the piston downwards via the first slider and connecting rod. At this point, air from the air chamber is sent to the sealing ring. When the sealing ring expands to fit tightly against the sealing groove, it seals the connection between the access door and the access opening. This design effectively enhances the sealing performance at the connection between the access door and the access opening, preventing moisture from the outside air from entering the busbar trunking through gaps.

[0013] 2. This utility model features an opening and closing assembly. Pulling the pull block upward causes it to slide the second slider along the second groove via the mounting rod, compressing the second spring. When the mounting rod moves out of the mounting hole, the access door can be opened by rotating the hinge to begin maintenance. After maintenance, the access door is rotated in the opposite direction to submerge it in the access opening. At this point, the mounting block moves between the upper and lower mounting seats. Then, releasing the pull block causes the second spring to rebound and, via the second slider, moves the mounting rod downward. When the mounting rod is inserted into the mounting hole, the mounting block is fixed in its current position, thus closing the access door. This design makes opening and closing the access door simpler and faster, effectively improving maintenance efficiency. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] A novel fire-resistant busbar trunking includes a busbar trunking body 1, an inspection port 2 on one side of the busbar trunking body 1, an inspection door 3 with a size adapted to the inspection port 2, a hinge 4 installed at the connection between the inspection door 3 and the busbar trunking body 1, a sealing component 5 at the connection between the inspection door 3 and the inspection port 2, and an opening and closing component 6 at the connection between the side of the inspection door 3 away from the hinge 4 and the busbar trunking body 1.

[0023] It should be noted that the sealing component 5 can effectively enhance the sealing performance at the connection between the inspection door 3 and the inspection port 2, thereby preventing moisture in the outside air from entering the busbar trunking body 1 through gaps. The opening and closing component 6 can make the opening and closing of the inspection door 3 simpler and faster, effectively improving maintenance efficiency.

[0024] like Figure 2 and Figure 4 As shown, the sealing assembly 5 includes a sealing groove 51, an installation groove 52, and a sealing ring 53. The sealing groove 51 is opened on the inner wall of the inspection port 2, the installation groove 52 is opened in the middle of the four sides of the inspection door 3, and the sealing ring 53 is installed inside the installation groove 52. The sealing ring 53 is made of rubber and is hollow inside.

[0025] It should be noted that after closing the inspection door 3, air is injected into the sealing ring 53 to make it expand. When the sealing ring 53 expands to fit tightly with the sealing groove 51, the connection between the inspection door 3 and the inspection port 2 can be sealed.

[0026] like Figure 4 and Figure 5 As shown, the sealing assembly 5 also includes an air chamber 54, a piston 55, and a connecting hole 56. The air chamber 54 is located inside the inspection door 3. The piston 55 is slidably connected to the air chamber 54 and is sized to match it. The connecting hole 56 is located on the bottom inner wall of the air chamber 54 and is connected to the sealing ring 53.

[0027] It should be noted that by sliding the piston 55 along the air chamber 54, air in the air chamber 54 can be sent to the sealing ring 53 through the connecting hole 56, or air in the sealing ring 53 can be drawn into the air chamber 54.

[0028] like Figure 4 As shown, the sealing assembly 5 also includes a first slide groove 57, a first slider 58, a first spring 59, and a connecting rod 510. The first slide groove 57 is opened on the outer surface of the inspection door 3 and its bottom is connected to the top of the air chamber 54. The first slider 58 is slidably connected to the first slide groove 57. The first spring 59 is installed inside the first slide groove 57 and its two ends are respectively fixedly connected to the top of the first slider 58 and the inner wall of the top of the first slide groove 57. The connecting rod 510 is movably connected to the air chamber 54 and the first slide groove 57 and its two ends are respectively fixedly connected to the bottom of the first slider 58 and the top of the piston 55.

[0029] It should be noted that the first slider 58 can be squeezed by sliding the first slider 58 upward along the first groove 57. During this process, the connecting rod 510 will drive the piston 55 to slide upward along the air chamber 54 in sync with the first slider 58. When the first slider 58 is released, the first spring 59 will rebound and drive the piston 55 to slide downward through the first slider 58 and the connecting rod 510.

[0030] like Figure 3 and Figure 6 As shown, the opening and closing assembly 6 includes an upper mounting base 61, a lower mounting base 62, a mounting block 63, a mounting hole 64, a through groove 65, and a mounting rod 66. The upper mounting base 61 and the lower mounting base 62 are both fixedly connected to the busbar trunking body 1 and are located on the side of the inspection port 2 away from the hinge 4. The mounting block 63 is fixedly connected to the side of the inspection door 3 away from the hinge 4 and is adapted to the spacing dimensions of the upper mounting base 61 and the lower mounting base 62. The mounting hole 64 passes through the mounting block 63, the through groove 65 passes through the upper mounting base 61, and the mounting rod 66 is movably connected to the through groove 65 and is adapted to the size of the mounting hole 64.

[0031] It should be noted that the mounting block 63 is placed between the upper mounting base 61 and the lower mounting base 62, and then the mounting rod 66 is inserted into the mounting hole 64. At this time, the mounting block 63 can be fixed in the current position, thereby completing the closing of the inspection door 3.

[0032] like Figure 6 As shown, the opening and closing assembly 6 also includes a second slide groove 67, a second slider 68, a second spring 69, and a pull block 610. The second slide groove 67 is formed in the inner wall of the through groove 65. The second slider 68 is fixedly connected to the outer periphery of the mounting rod 66 and slidably connected to the second slide groove 67. The second spring 69 is sleeved on the outer periphery of the mounting rod 66 and its two ends are respectively fixedly connected to the top of the second slider 68 and the top inner wall of the second slide groove 67. The pull block 610 is fixedly connected to the top of the mounting rod 66.

[0033] It should be noted that pulling the pull block 610 upward will cause the second slider 68 to slide upward along the second slide groove 67 via the mounting rod 66 and compress the second spring 69. Releasing the pull block 610 will cause the second spring 69 to rebound, which will then cause the mounting rod 66 to move downward via the second slider 68.

[0034] In a specific application scenario, when the busbar trunking body 1 needs to be inspected, firstly, pull the pull block 610 upwards so that it drives the second slider 68 to slide upwards along the second slide groove 67 via the mounting rod 66, thus compressing the second spring 69. When the mounting rod 66 moves out of the mounting hole 64, the first slider 58 slides upwards along the first slide groove 57, thus compressing the first spring 59. During this process, the connecting rod 510 drives the piston 55 to slide upwards along the air chamber 54 and draws the air in the sealing ring 53 into the air chamber 54 through the connecting hole 56. When the sealing ring 53 deflates and moves out of the sealing groove 51, the inspection door 3 is opened by rotating the hinge 4, and then the busbar trunking body 1 can be inspected. After the inspection is completed... Afterwards, rotate the inspection door 3 in the reverse direction so that it is submerged in the inspection port 2. At this time, the mounting block 63 moves between the upper mounting seat 61 and the lower mounting seat 62. Then, release the pull block 610. The second spring 69 rebounds and drives the mounting rod 66 downward through the second slider 68. When the mounting rod 66 is inserted into the mounting hole 64, the mounting block 63 is fixed in the current position, thus completing the closing of the inspection door 3. Then, release the first slider 58. The first spring 59 rebounds and drives the piston 55 downward through the first slider 58 and the connecting rod 510. At this time, the air in the air chamber 54 is sent to the sealing ring 53. When the sealing ring 53 expands to fit tightly with the sealing groove 51, the connection between the inspection door 3 and the inspection port 2 is sealed.
