Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar that is easy to dissipate heat and prevent fire. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] However, in order to ensure fire resistance, traditional busbar trunking is filled with a large amount of fireproof material. The cluttered fireproof material results in low space utilization and lacks independent heat dissipation space and structure, thus leading to poor heat dissipation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor heat dissipation in traditional busbar trunking and to provide an adjustable rotating display device for enterprise service information.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a busbar trunking system that facilitates heat dissipation and fire prevention, including...

[0007] Busbar trunking, wherein each end of the busbar trunking is provided with a connector;

[0008] The busbar trunking is formed by four outer shell plates. The interior of the busbar trunking is provided with two first internal partition plates in a horizontal direction. The two first internal partition plates divide the interior of the busbar trunking into a first installation chamber, a second installation chamber and a third installation chamber from top to bottom.

[0009] Both the first and third mounting chambers are provided with a third internal partition plate, and the third internal partition plate and the outer shell plate form a third partition chamber; the third internal partition plate and the first internal partition plate form a heat dissipation chamber.

[0010] The second mounting chamber is vertically slidably provided with two second internal partition plates, which divide the second mounting chamber from left to right into a first partition chamber, a conductive plate mounting chamber, and a second partition chamber.

[0011] The conductive plate mounting chamber is provided with a conductive sheet, the two ends of which are connected to the connector. An insulating heat-conducting sleeve is provided on the conductive sheet. Heat sink mounting slots are provided on the upper and lower side walls of the conductive plate mounting chamber. Heat sinks are embedded in both heat sink mounting slots. The heat-conducting end of the heat sink abuts against the conductive sheet. The heat-dissipating end of the heat sink is located in the heat dissipation chamber.

[0012] Fireproof cotton is provided in the first partition chamber, the second partition chamber and the third partition chamber.

[0013] Furthermore, each of the first internal partition plates is provided with a horizontal partition plate adjustment groove, and bolts are installed on the partition plate adjustment groove. Each of the second internal partition plates is connected to the first internal partition plate by bolts.

[0014] Furthermore, a plurality of heat dissipation holes are provided on the side wall of the heat dissipation chamber; an air inlet pipe is provided on the outside of the busbar groove, and the air inlet pipe is connected to the heat dissipation chamber through the heat dissipation holes.

[0015] Furthermore, a temperature detection sensor is provided on the heat dissipation chamber.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting the first and second internal partition plates, the conductive plate mounting chamber for installing conductive sheets is located in the center of the busbar trunking, thus achieving a wrapping effect. After stuffing fireproof cotton around it, the fireproof effect of the busbar trunking is enhanced, resulting in good safety performance. Furthermore, by setting the third internal partition plate, a separate heat dissipation chamber is created inside the busbar trunking, which not only improves the utilization rate of the internal space but also further ensures the heat dissipation effect of the busbar trunking.

[0018] 2. By incorporating heat sinks, ventilation holes, temperature sensors, and air inlets, a superior heat dissipation structure is added inside the busbar trunking. This not only improves heat dissipation and prevents overheating during use, preventing accidents, but also allows for a more intuitive display of the internal temperature of the busbar trunking when used with temperature sensors and air inlets. Operators can then connect to external ventilation equipment via the air inlets to promptly cool the inside of the busbar trunking, ensuring the normal operation of the device.

[0027] Example

[0028] like Figures 1-5 As shown

[0029] A busbar trunking system that facilitates heat dissipation and fire resistance, including

[0030] Busbar 2, with connectors 1 at both ends; preferably, air inlet pipes 3 are connected to both sides of the busbar 2 to connect to external ventilation equipment to accelerate the airflow inside the busbar 2, thereby improving the heat dissipation effect;

[0031] Specifically, the busbar 2 is formed by enclosing four shell plates 21 in the shape of "冖" through bolt connection at the head and tail. Two first internal partition plates 22 are horizontally arranged inside the busbar 2. Similarly, the first internal partition plates 22 are also connected to the side walls of the busbar 2 by bolts. The two first internal partition plates 22 divide the inside of the busbar 2 into a first installation chamber 211, a second installation chamber 212, and a third installation chamber 213 from top to bottom in sequence;

[0032] Third internal partition plates 24 in the shape of an arch spanning front and back are provided in both the first installation chamber 211 and the third installation chamber 213. The front and rear ends of the third internal partition plates 24 are bolt-connected to the joint 1. A third partition chamber 2111 is formed between the third internal partition plates 24 and the shell plates 21; a heat dissipation chamber 2112 is formed between the third internal partition plates 24 and the first internal partition plates 22; a temperature detection sensor 7 is provided in the heat dissipation chamber 2112. A number of heat dissipation holes 25 are opened on the left and right side walls of the heat dissipation chamber 2112, and the heat dissipation chamber 2112 is communicated with the air inlet pipe 3 through the heat dissipation holes 25;

[0033] Two second internal partition plates 23 are vertically slidably provided in the second installation chamber 212. The two second internal partition plates 22 divide the second installation chamber 212 into a first partition chamber 2121, a conductive plate installation chamber 2122, and a second partition chamber 2123 from left to right in sequence;

[0034] Preferably, partition plate adjustment sliding grooves 222 are horizontally opened on the first internal partition plates 22. Bolts 8 are inserted through the partition plate adjustment sliding grooves 222. The second internal partition plates 23 are all connected to the first internal partition plates 22 by bolts 8.

[0035] Through this solution, the distance between the two second internal partition plates 23 can be adjusted, so that the width of the conductive plate installation chamber 2122 can be adjusted, and then the clamping of conductive sheets 4 of different specifications can be realized, and the applicable range is wider.

[0036] Conductive sheets 4 are provided in the conductive plate installation chamber 2121. The two ends of the conductive sheets 4 are connected to the joint 1. Insulating heat-conducting sleeves 41 are provided on the conductive sheets 4; heat dissipation fin clamping grooves 221 are opened on the upper and lower side walls of the conductive plate installation chamber 2121. Heat dissipation fins 6 are embedded in the two heat dissipation fin clamping grooves 221. The heat-conducting ends of the heat dissipation fins 6 abut against the conductive sheets 4, and the heat-dissipating ends of the heat dissipation fins 6 are arranged in the heat dissipation chamber 2112;

[0037] Through this solution, when the busbar 2 is in use, the heat generated on the conductive sheets 4 can be transferred to a dedicated heat dissipation chamber 2112 for heat dissipation, so that a heat dissipation structure with better heat dissipation performance is added inside the busbar 2, which not only improves the heat dissipation effect but also prevents accidents caused by excessive internal temperature of the busbar 2 during use.

[0038] Furthermore, fireproof cotton 5 is provided in the first partition chamber 2121, the second partition chamber 2123 and the third partition chamber 2111.

[0039] This design, by setting up a first internal partition plate 22 and a second internal partition plate 23, ensures that the conductive plate mounting chamber 2121 for installing the conductive sheet 4 is located in the center of the busbar trough 2, thus achieving a wrapping effect. After stuffing fireproof cotton 5 around it, the fireproof effect of the busbar trough 2 is enhanced, resulting in good safety performance. Furthermore, by setting up a third internal partition plate 24, a separate heat dissipation chamber is created inside the busbar trough, which not only improves the utilization rate of the internal space but also further ensures the heat dissipation effect of the busbar trough 2. In addition, when used in conjunction with a temperature detection sensor 7 and an air inlet pipe 3, the internal temperature of the busbar trough 2 can be displayed more intuitively. Workers can then connect to external ventilation equipment through the air inlet pipe 3 to cool the inside of the busbar trough 2 in a timely manner, ensuring the normal operation of the device.

[0040] In order to ensure that the conductive plate mounting chamber 2121 is enclosed and located at the center of the busbar trough 2, preferably, the first internal partition plate 22 or the second internal partition plate 23 may also be provided in a configuration of not less than two pieces.

[0041] How this device works:

[0042] Before use, connect and install the outer shell plate 21, the first internal partition plate 22, the second internal partition plate 23 and the third internal partition plate 24 with bolts 8. Install the conductive sheet 4 with the insulating heat-conducting sleeve 41 into the conductive plate mounting chamber 2122 and fix it. Then, embed the heat sink 6 into the heat sink mounting slot 221 so that its heat-conducting end abuts against the conductive sheet 4 and its heat-dissipating end is installed in the heat dissipation chamber 2112. After completion, insert the fireproof cotton 5. Then install and fix the temperature detection sensor 7, the air inlet pipe 3 and the entire device. After completion, fix the two connectors 1 to both ends of the busbar trough 2 with bolts and it can be put into use.

[0043] In use, the heat generated on the conductive sheet 4 is transferred to the heat dissipation chamber 2112 through the heat sink 6, and then dissipated through the heat dissipation holes 25. The temperature in the heat dissipation chamber 2112 is fed back by the temperature detection sensor 7. When the temperature is too high, the operator connects the external ventilation equipment to the air inlet pipe 3 and starts the ventilation to allow the hot air in the heat dissipation chamber 2112 to be discharged as soon as possible, thereby achieving cooling. In the event of a fire, the external fireproof cotton 5 can achieve a flame-retardant effect, thus achieving a fireproof function.

[0044] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
