Description

Technical Field

[0001] The invention relates to the field of busbar applications, in particular to a terminal busbar in a machine room with strong fire resistance. Background Art

[0002] Internet Data Center (IDC) is a standardized telecommunications professional-grade computer room environment established by telecommunications departments using existing Internet communication lines and bandwidth resources to provide enterprises and governments with a full range of services such as server hosting, leasing, and related value-added services. These environments usually consume a lot of electricity, and traditional cables as power transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections, and bus ducts have emerged as a new type of distribution conductor.

[0003] High-quality insulating materials are used in the bus duct, which improves the safety and reliability of the bus duct and makes the entire system more perfect.

[0004] For example, the Chinese utility model patent with announcement number CN203150921U provides a data room bus duct, including a bus duct body and a distribution box connected to the bus duct body; the distribution box is connected to a plug rod for inserting into the bus duct body, and the plug rod is inserted into one end of the distribution box; the top of the plug rod is protrudingly provided with a pre-positioning protrusion for plugging into the card slot at the upper end of the bus duct body. The beneficial effects of the utility model are mainly reflected in: the distribution box can be well fixed to the bus duct while ensuring the contact area between the distribution box and the bus duct, and can be moved as needed, which is convenient to use.

[0005] However, the above busbar considers the portable installation aspects, but ignores the fire resistance of the busbar. Therefore, the present application makes corresponding improvements. Summary of the invention

[0006] The object of the present invention is to provide a terminal busbar in a machine room with strong fire resistance, which has good fire resistance and is easy to use.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a terminal busbar of a machine room with strong fire resistance, comprising a busbar duct, a conductor located in the busbar duct, and an insulating card plate for installing the conductor, the busbar duct is surrounded by a fireproof sleeve made of a fireproof material, a flow pipe is arranged in the fireproof sleeve, the flow pipe is connected to a suction device, and a cooling medium is arranged in the flow pipe;

[0008] A fireproof ring is evenly arranged outside the fireproof sleeve. The fireproof ring is provided with evenly distributed air outlet holes penetrating through it. The air outlet holes are connected with an air flow pipeline, and the air flow pipeline is located inside the fireproof sleeve. The air flow pipeline is connected with a gas source for providing high-speed air flow.

[0009] Through the above technical solution, a flow pipe is arranged in the fireproof sleeve, and a suction device is used to make the cooling medium flow in the flow pipe. Therefore, during the flowing process, the high-temperature heat in the environment is continuously taken away. Therefore, the high temperature only affects the temperature of the fireproof sleeve, and has little impact on the busbar trunking, thus achieving the purpose of enhancing the fire resistance of the busbar trunking; a fireproof ring is arranged. Since the gas source ejects high-speed air flow through the air outlet holes, the high-speed air flow flows along the surface of the fireproof sleeve. On the one hand, the high-speed flowing gas can take away the heat of the fireproof sleeve and cool it. On the other hand, due to the high gas flow rate of the high-speed gas, near the surface of the fireproof sleeve, the conditions for ignition are not available and there is no ignition source, thus avoiding the fireproof sleeve being too close to the ignition source, thereby enhancing the fire resistance.

[0010] Preferably, the flow pipe is arranged in a spiral shape.

[0011] Through the above technical solution, the flow pipe is arranged in a spiral shape. On the one hand, it can increase the distribution density and the flowing area of the flow pipe in the fireproof sleeve. On the other hand, compared with other forms of arrangement, such as the arrangement of multiple parallel flow pipes, arranging it in a spiral shape only requires one flow pipe to complete the connection between the flow pipe and the suction device, which is convenient for use.

[0012] Preferably, the cooling medium is water.

[0013] Through the above technical solution, since the specific heat capacity of water is much higher than that of gas, in a high-temperature environment, under the condition of the same temperature difference, compared with gas, it can absorb more heat, so it can effectively play a role in cooling.

[0014] Preferably, the flow pipe is communicated with a communicating small pipe communicated with the outside. A conical plunger is arranged in the communicating small pipe. The diameter of the conical plunger decreases in the direction close to the communicating small pipe. The conical plunger is wrapped in the fireproof sleeve, and the minimum thickness of the fireproof sleeve outside the conical plunger is 0.5 mm to 2 mm.

[0015] Through the above technical solution, after the fireproof sleeve exists for a period of time under high-temperature conditions, the material on its surface will be damaged, so its physical properties will also decline. At the same time, the setting of the conical plunger, combined with the damage of its surface material, and the water generates a great pressure on the conical plunger. The generation of the great pressure can choose to block the other end of the flow pipe, so the conical plunger opens the communicating small pipe. After the communicating small pipe is opened, the flowing out water can not only extinguish the fire, but also significantly reduce the temperature in the environment of the fireproof sleeve.

[0016] Preferably, the gas provided by the gas source is an inert gas.

[0017] Through the above technical solution, although high-speed air can also achieve the effect of extinguishing fire, due to the presence of oxygen in the air which has an effect of assisting combustion for fire, obviously this result is not particularly ideal. Therefore, we use an inert gas, which can not only achieve the effect of extinguishing fire, but also make the fireproof sleeve within the protection range of the inert gas. Thus, its fire resistance can be seen.

[0018] Preferably, the air outlet is connected to a nozzle, and the nozzle includes a flat air outlet, and the orientation of the flat air outlet is the surface of the fireproof sleeve.

[0019] Through the above technical solution, the flat air outlet with a flat shape can shape the high-speed air flow, making the direction of the air flow closer to the surface of the fireproof sleeve, which is beneficial to increasing the fire resistance.

[0020] Preferably, a protective net for preventing it from being blocked is connected to the flat air outlet.

[0021] Through the above technical solution, since the flat air outlet is in an open state in the non-working state, a lot of dust or other sundries often enter. In order to prevent the flat air outlet from being blocked, a protective net is provided to avoid the phenomenon that it cannot be used normally.

[0022] Preferably, a ring-shaped guide plate is further provided on the fireproof ring. The guide plate includes an annular part and a contraction part. The annular part and the contraction part are integrally formed and connected to the port of the fireproof ring. A ring groove is provided on the fireproof ring, and the ring groove is clamped with the annular part.

[0023] Through the above technical solution, the guide plate can be conveniently installed on the fireproof ring through the clamping of the annular part and the ring groove. The contraction part with a contraction setting can guide the gas, making the gas flow close to the wall surface.

[0024] Preferably, stator blades are inclinedly provided on the inner wall surfaces of the annular part and the contraction part.

[0025] Through the above technical solution, the gas ejected from the nozzle is guided by the stator blades so that it rotates and flows along the fireproof sleeve, thereby better improving the fireproof effect.

[0026] Preferably, a fireproof coating is provided on the surface of the guide plate.

[0027] Through the above technical solution, the fireproof coating can improve the fire resistance of the guide plate, thereby better protecting the nozzle and guiding the air flow ejected from the nozzle.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] (1) A flow tube is arranged inside the fireproof sleeve, and through a suction device, the cooling medium flows inside the flow tube. Therefore, during the flow process, the high-temperature heat in the environment is continuously carried away. Thus, the high temperature only affects the temperature of the fireproof sleeve and has little impact on the busbar trunking, thereby achieving the purpose of enhancing the fire resistance of the busbar trunking;

[0030] (2) A fireproof ring is provided. Since the gas source ejects high-speed air flow through the flat air outlet nozzle, the high-speed air flow flows along the surface of the fireproof sleeve. On the one hand, the high-speed flowing gas can carry away the heat of the fireproof sleeve and cool it. On the other hand, due to the high gas flow rate of the high-speed gas, near the surface of the fireproof sleeve, the conditions for ignition are not available and there is no ignition source, thus avoiding the fireproof sleeve being too close to the ignition source, thereby enhancing the fire resistance.;

[0031] (3) After the fireproof sleeve has existed for a period of time under high-temperature conditions, the material on its surface will be damaged, so its physical properties will also decline. At the same time, the setting of the conical plunger, combined with the damage of the surface material, and the water generates a great pressure on the conical plunger. Then the conical plunger opens the connecting small tube. After the connecting small tube is opened, the flowing out water can not only extinguish the fire but also significantly reduce the temperature in the environment of the fireproof sleeve;

[0032] (4) The settings of the guide plate and the stator blades enable the air flow to flow at high speed along the surface of the fireproof sleeve in a rotating manner. Since the air flow rotates and flows, it can minimize the blind areas of gas flow to the greatest extent, thereby covering the entire surface of the fireproof sleeve, so that it has good fire resistance.

Detailed implementation mode

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-5 , an embodiment provided by the present invention:

[0041] A fire-resistant end busbar for a computer room includes a busbar trunking 1, a conductor 2 located inside the busbar trunking 1, and an insulating clamping plate 3 for installing the conductor 2.

[0042] A fireproof sleeve 4 made of fireproof material is arranged around the busbar trunking 1. A flow pipe 5 is arranged inside the fireproof sleeve 4. The flow pipe 5 is connected to a suction device 6, and a cooling medium 7 is arranged inside the flow pipe 5.

[0043] The flow pipe 5 is arranged in a spiral shape. The flow pipe 5 is arranged in a spiral shape. On the one hand, it can increase the distribution density and the flowing area of the flow pipe 5 in the fireproof sleeve 4. On the other hand, compared with other forms of arrangement, such as the arrangement of multiple parallel flow pipes 5, arranging it in a spiral shape only requires one flow pipe 5 to complete the connection between the flow pipe 5 and the suction device 6, which is convenient for use.

[0044] The cooling medium 7 is water. Since the specific heat capacity of water is much higher than that of gas, in a high-temperature environment, under the condition of the same temperature difference, compared with gas, it can absorb more heat, so it can effectively play a role in cooling.

[0045]

[0046] ​The flow tube 5 is connected to a communicating small tube 12 that communicates with the outside. A conical plunger 13 is arranged inside the communicating small tube 12, and the diameter of the conical plunger 13 decreases in the direction close to the communicating small tube 12. The conical plunger 13 is wrapped in a fireproof sleeve 4, and the minimum thickness of the fireproof sleeve 4 outside the conical plunger 13 is 0.5 mm to 2 mm.

[0047] After the fireproof sleeve 4 exists for a period of time under high-temperature conditions, the material on its surface will be damaged, so its physical properties will also decline. At the same time, the setting of the conical plunger 13, combined with the damage of its surface material, and at the same time, water generates a great pressure on the conical plunger 13. The generation of the great pressure can choose to block the other end of the flow tube 5. Then the conical plunger 13 opens the communicating small tube 12. After the communicating small tube 12 is opened, the flowing out water can not only extinguish the fire, but also significantly reduce the temperature in the environment of the fireproof sleeve 4.

[0048] Fireproof rings 8 are evenly arranged outside the fireproof sleeve 4. Through holes 9 are penetrated through the fireproof rings 8 and are evenly distributed. The through holes 9 are connected to an air flow pipeline 10. The air flow pipeline 10 is located inside the fireproof sleeve 4, and the air flow pipeline 10 is connected to a gas source 11 for providing high-speed air flow. By setting the fireproof rings 8, since the gas source 11 ejects high-speed air flow through the through holes 9, the high-speed air flow flows along the surface of the fireproof sleeve 4. On the one hand, the high-speed flowing gas can take away the heat of the fireproof sleeve 4 and cool it. On the other hand, due to the high gas flow rate of the high-speed gas, near the surface of the fireproof sleeve 4, the conditions for catching fire do not exist and there is no ignition source, thus avoiding the fireproof sleeve 4 being too close to the ignition source, thereby enhancing the fire resistance.

[0049] The gas provided by the gas source 11 is an inert gas. Although high-speed air can also play the role of extinguishing fire, because the existence of oxygen in the air has an effect of assisting combustion for fire, obviously this result is not particularly ideal. Therefore, we use inert gas, which can not only play the role of extinguishing fire, but also make the fireproof sleeve 4 within the protection range of the inert gas. Thus, its fire resistance can be seen.

[0050] The through holes 9 are connected to nozzles 14. Each nozzle 14 includes a flat air outlet nozzle 15, and the orientation of the flat air outlet nozzle 15 is the surface of the fireproof sleeve 4. The flat air outlet nozzle 15 with a flat shape can shape the high-speed air flow, making the direction of the air flow closer to the surface of the fireproof sleeve 4, which is beneficial to increasing the fire resistance.

[0051] The flat air outlet nozzle 15 is connected with a protective net 16 to prevent it from being blocked. Since the flat air outlet nozzle 15 is in an open state in the non-working state, a lot of dust or other sundries often enter. In order to prevent the flat air outlet nozzle 15 from being blocked, the protective net 16 is set to avoid the phenomenon that it cannot be used normally.

[0052] A ring-shaped guide plate is also provided on the fireproof ring 8. The guide plate includes an annular portion 17 and a constricted portion 18. The annular portion 17 and the constricted portion 18 are integrally formed and connected to the port of the fireproof ring 8. A ring groove 21 is provided on the fireproof ring 8, and the ring groove 21 is engaged with the annular portion 17. The guide plate can be conveniently installed on the fireproof ring 8 through the engagement of the annular portion 17 and the ring groove 21. The constricted portion 18 arranged in a constricted manner can guide the gas, causing the gas to flow close to the wall surface.

[0053] The inner wall surfaces of the annular portion 17 and the constricted portion 18 are provided with stator vanes 19 arranged obliquely. The stator vanes 19 guide the lift ejected from the nozzle 14 so that it rotates and flows along the fireproof sleeve 4, thereby better improving the fireproof effect.

[0054] The surface of the guide plate is provided with a refractory coating 20. The refractory coating 20 can improve the fireproof performance of the guide plate, thereby better protecting the nozzle 14 and guiding the airflow ejected from the nozzle 14.

[0055] In summary, the beneficial effects of the present invention are as follows: (1) A flow pipe 5 is arranged in the fireproof sleeve 4, and through the suction device 6, the cooling medium 7 flows in the flow pipe 5. Therefore, during the flow process, the high-temperature heat in the environment is continuously carried away. Therefore, the high temperature only affects the temperature of the fireproof sleeve 4, and has little impact on the busbar trunking 1, thereby achieving the purpose of enhancing the fire resistance of the busbar trunking 1; (2) A fireproof ring 8 is provided. Since the gas source 11 ejects a high-speed air flow through the flat air outlet nozzle 15, the high-speed air flow flows along the surface of the fireproof sleeve 4. On the one hand, the high-speed flowing gas can carry away the heat of the fireproof sleeve 4 and cool it. On the other hand, due to the high gas flow rate of the high-speed gas, near the surface of the fireproof sleeve 4, the conditions for ignition are not available and there is no ignition source, thereby avoiding the fireproof sleeve 4 being too close to the ignition source, thus enhancing the fire resistance; (3) After the fireproof sleeve 4 exists at high temperature for a period of time, the material on its surface will be damaged, so its physical properties will also decline. At the same time, the conical plunger 13 is provided. Coupled with the damage of the material on its surface, and at the same time, water generates a great pressure on the conical plunger 13, so the conical plunger 13 opens the communication small pipe 12. After the opened communication small pipe 12, the flowing out water can not only extinguish the fire, but also significantly reduce the temperature in the environment of the fireproof sleeve 4; (4) The arrangement of the guide plate and the stator vanes enables the air flow to rotate and flow at a high speed along the surface of the fireproof sleeve. Since the air flow rotates and flows, the blind area of gas flow can be minimized to the greatest extent, thereby covering the entire surface of the fireproof sleeve, so that it has good fire resistance.

[0056] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Thus, all changes that fall within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
