Description

Technical Field

[0001] The present invention relates to the technical field of power distribution systems, and in particular to a heat dissipation power distribution system. Background Art

[0002] There are several distribution cabinets in the distribution room, and various electrical components are usually placed inside the distribution cabinet. These electrical components will continue to generate heat when they are working continuously. If this heat cannot be discharged to the outside of the distribution cabinet in time, the service life of the electrical components will be damaged.

[0003] Air conditioners are usually installed in the distribution room to dissipate heat from the distribution cabinet. At the same time, the hot air in the distribution cabinet is exchanged with the cold air in the distribution room. However, this requires more air conditioners for cooling, resulting in a large cooling power required in the distribution room and poor cooling efficiency. Summary of the invention

[0004] In order to reduce the power required for cooling the power distribution room, the present invention provides a heat dissipation power distribution system.

[0005] The present invention provides a heat dissipation power distribution system, which adopts the following technical solution:

[0006] A heat dissipation power distribution system, comprising a power distribution room, a plurality of power distribution cabinets arranged in the power distribution room, and a heat dissipation duct, one end of the heat dissipation duct extending out of the power distribution room, and a heat dissipation fan for discharging hot air out of the power distribution room is arranged on the heat dissipation duct;

[0007] The heat dissipation air duct is connected to a plurality of vertically arranged branch pipes, and one end of the branch pipe away from the heat dissipation air duct is connected to the heat dissipation hole of the power distribution cabinet; an end of the branch pipe close to the heat dissipation air duct is provided with an inclined air guide plate, one end of the air guide plate extends into the heat dissipation air duct, and the air guide plate is inclined toward the gas flow direction in the heat dissipation air duct.

[0008] By adopting the above technical solution, the heat dissipation fan works, so that the hot air generated by several distribution cabinets in the distribution room is transported to the heat dissipation duct through the corresponding branch pipes, and then discharged outside the distribution room through the heat dissipation duct, so that the hot air generated by the distribution cabinet does not need to directly exchange heat with the air in the distribution room, reducing the power required for cooling the distribution room. In addition, the hot air entering the heat dissipation duct from the branch pipe is guided by the air guide plate, reducing the angle between the airflow direction in the branch pipe and the airflow direction in the heat dissipation duct, thereby reducing the wind resistance in the process of airflow entering the heat dissipation duct from the branch pipe, thereby improving the heat dissipation efficiency.

[0009] Furthermore, the branch pipe includes a fixed pipe and a movable pipe, the fixed pipe is fixedly connected to the heat dissipation duct, the movable pipe is slidably sleeved outside the fixed pipe, and a sealing component is provided at the connection between the fixed pipe and the movable pipe.

[0010] By adopting the above technical solution, for distribution cabinets at different heights in the distribution room, the position of the movable pipe can be slid to extend or shorten the length of the branch pipe, thereby adapting to distribution cabinets of different heights and improving adaptability; at the same time, the sealing component effectively improves the sealing of the connection between the fixed pipe and the movable pipe.

[0011] Furthermore, the sealing assembly comprises a clamping ring and a sealing ring, wherein the clamping ring is sleeved on the fixed tube, and one end of the sealing ring extends into a gap at the connection between the fixed tube and the movable tube.

[0012] Furthermore, the top wall of the movable tube is provided with an inclined guiding surface, and the side wall of the sealing ring close to the movable tube is provided with an inclined surface for fitting with the guiding surface; and a deformation cavity is provided in the sealing ring.

[0013] By adopting the above technical solution, due to certain impacts and vibrations generated during the air flow process, the connection between the fixed tube and the movable tube is prone to loosening over time, resulting in hot air leakage. A deformation cavity is provided in the sealing ring, and during the vibration of the movable tube, the sealing ring will be squeezed to cause deformation. The sealing ring absorbs energy and reduces the vibration of the movable tube and the fixed tube, thereby improving the sealing effect.

[0014] Furthermore, a sealing tube is provided on a sealing sleeve at one end of the movable tube close to the fixed tube, and the sealing tube is in sealing contact with the outer wall of the clamping ring.

[0015] Furthermore, the sealing tube is connected to a trachea, and an air bag is sleeved on the trachea.

[0016] By adopting the above technical solution, when the connection between the fixed tube and the movable tube becomes loose or the sealing ring is damaged, the hot air in the movable tube is usually discharged through the gap between the sealing ring and the fixed tube, and then enters the sealing tube, and enters the airbag through the air pipe, causing the airbag to expand. At this time, the maintenance personnel can easily determine the branch pipe where the leak occurs, without the need to regularly inspect each branch pipe, thereby improving the efficiency and convenience of maintenance.

[0017] Furthermore, the air guide plate is hinged in a fixed tube, an elastic member for driving the air guide plate to deflect downward is provided in the fixed tube, a driving block is fixedly provided on the top wall of the air guide plate, a pull rope is fixedly connected to the driving block, an opening is provided on the side wall of the fixed tube for the pull rope to pass through, and an adjusting member for adjusting the length of the pull rope is provided on the fixed tube.

[0018] By adopting the above technical solution, the length of the pull rope is adjusted through the adjusting member, thereby adjusting the deflection angle of the air guide plate, and the operation is simple and convenient.

[0019] Furthermore, a sleeve is fixedly provided on the side wall of the fixed tube in the vertical direction, a first damping platform and a second damping platform are slidably provided in the sleeve, and a tension spring is fixedly connected between the first damping platform and the second damping platform.

[0020] By adopting the above technical solution, in the process of airflow entering the heat dissipation duct from the branch pipe, the airflow directly impacts the air guide plate, and at the same time, a part of the airflow in the heat dissipation duct will also impact the air guide plate. Under the joint action of the two airflows, the air guide plate will cause a certain vibration. In this process, the pull rope is tightened or relaxed, and at the same time, under the action of the tension spring, the first damping platform and the second damping platform slide in the sleeve. Under the action of friction, the first damping platform and the second damping platform convert the energy generated by the vibration into heat energy, thereby achieving the effect of shock absorption and energy dissipation, and reducing the vibration of the air guide plate; at the same time, due to the existence of the air guide plate, the energy of the two airflows is reduced, and the direct effect of the two airflows on the heat dissipation pipe is reduced, thereby preventing the heat dissipation pipe from vibrating, and preventing the heat dissipation pipe and the branch pipe from loosening due to vibration.

[0021] Furthermore, the adjusting member is configured as an adjusting bolt, the adjusting bolt is threadedly penetrated through the bottom wall of the sleeve, and the adjusting bolt is rotationally connected to the second damping platform.

[0022] Furthermore, a suspension rope is fixedly connected to the wind guide plate, and a damping ball is fixedly connected to the suspension rope.

[0023] By adopting the above technical solution, if a power distribution cabinet is out of use or in the maintenance stage, the air guide plate can be closed, the restriction of the pull rope can be released, and the air guide plate can be deflected in the horizontal direction under the tension of the elastic member and the damping ball until the branch pipe outlet at that location is completely closed to prevent the airflow in the heat dissipation duct from being discharged downward from the branch pipe at that location. At the same time, during normal use, when the air guide plate vibrates, it will drive the damping ball to shake, and the damping ball will play a role in hindering the vibration of the air guide plate, and play a role in shock absorption and energy dissipation, effectively reducing the vibration amplitude of the air guide plate.

[0024] In summary, the present invention includes at least one of the following beneficial technical effects:

[0025] 1. When the cooling fan is working, the hot air generated by several power distribution cabinets in the power distribution room is transported to the cooling duct through the corresponding branch pipes, and then discharged outside the power distribution room through the cooling duct, so that the hot air generated by the power distribution cabinet does not need to directly exchange heat with the air in the power distribution room, reducing the power required for cooling the power distribution room. In addition, the hot air entering the cooling duct from the branch pipe is guided by the air guide plate, reducing the angle between the airflow direction in the branch pipe and the airflow direction in the cooling duct, thereby reducing the wind resistance in the process of airflow entering the cooling duct from the branch pipe, thereby improving the cooling efficiency.

[0026] 2. When the connection between the fixed pipe and the movable pipe becomes loose or the sealing ring is damaged, the hot air in the movable pipe is usually discharged through the gap between the sealing ring and the fixed pipe, then enters the sealing pipe, and enters the airbag through the air pipe, causing the airbag to expand. At this time, the maintenance personnel can easily determine the branch pipe where the leak occurs, without the need to regularly inspect each branch pipe, thereby improving the efficiency and convenience of maintenance.

[0027] 3. When the airflow enters the heat dissipation duct from the branch pipe, the airflow directly impacts the air guide plate, and at the same time, part of the airflow in the heat dissipation duct will also impact the air guide plate. Under the joint action of the two airflows, the air guide plate will vibrate to a certain extent. During this process, the pull rope is tightened or loosened, and at the same time, under the action of the tension spring, the first damping platform and the second damping platform slide in the sleeve. Under the action of friction, the first damping platform and the second damping platform convert the energy generated by the vibration into heat energy, thereby achieving the effect of shock absorption and energy dissipation, and reducing the vibration of the air guide plate; at the same time, due to the existence of the air guide plate, the energy of the two airflows is reduced, and the direct effect of the two airflows on the heat dissipation pipe is reduced, thereby preventing the heat dissipation pipe from vibrating, and preventing the heat dissipation pipe and the branch pipe from loosening due to vibration.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 5 The present invention is described in further detail.

[0035] The embodiment of the present invention discloses a heat dissipation power distribution system.

[0036] Reference Figure 1 A heat dissipation power distribution system includes a power distribution room 1, a plurality of power distribution cabinets 11 arranged in the power distribution room 1, and a heat dissipation air duct 12. The heat dissipation air duct 12 is horizontally suspended on the ceiling of the power distribution room 1 through a bracket 13. One end of the heat dissipation air duct 12 extends out of the power distribution room 1, and a heat dissipation fan 121 for discharging hot air out of the power distribution room 1 is provided on the heat dissipation air duct 12. The heat dissipation fan 121 is arranged at the air outlet of the heat dissipation air duct 12.

[0037] Reference Figure 2 The heat dissipation air duct 12 is connected with a plurality of vertically arranged branch pipes 2, and each power distribution cabinet 11 is provided with a branch pipe 2. The top of the branch pipe 2 is fixedly arranged on the top wall of the power distribution cabinet 11, and one end of the branch pipe 2 away from the heat dissipation air duct 12 is connected with the heat dissipation hole of the power distribution cabinet 11. The branch pipe 2 includes a fixed pipe 21 and a movable pipe 22. The fixed pipe 21 is fixedly connected with the heat dissipation air duct 12, and the movable pipe 22 is slidably sleeved outside the fixed pipe 21.

[0038] Reference Figure 3 and Figure 4 A sealing assembly 3 is provided at the connection between the fixed tube 21 and the movable tube 22. The sealing assembly 3 includes a clamping ring 31 and a sealing ring 32. The sealing ring 32 is made of rubber. The clamping ring 31 is sleeved on the fixed tube 21. One end of the sealing ring 32 extends into the gap at the connection between the fixed tube 21 and the movable tube 22. An embedding groove is provided on the bottom wall of the clamping ring 31. The top of the sealing ring 32 is embedded in the embedding groove. The embedding groove is provided at one end of the clamping ring 31 close to the fixed tube 21, so that the sealing ring 32 can be tightly pressed against the side wall of the fixed tube 21.

[0039] Reference Figure 3 and Figure 4 In order to facilitate the sealing ring 32 to be inserted into the gap between the fixed tube 21 and the movable tube 22, the top wall of the movable tube 22 is provided with an inclined guide slope 221, and the side wall of the sealing ring 32 close to the movable tube 22 is provided with an inclined surface for fitting with the guide slope 221. A deformation cavity 321 is provided in the sealing ring 32.

[0040] Due to certain impacts and vibrations generated during the air flow, the connection between the fixed tube 21 and the movable tube 22 is prone to loosening over time, resulting in hot air leakage. A deformation cavity 321 is provided in the sealing ring 32. During the vibration of the movable tube 22, the sealing ring 32 will be squeezed to deform. The sealing ring 32 absorbs energy to reduce the vibration of the movable tube 22 and the fixed tube 21, thereby improving the sealing effect.

[0041] Reference Figure 3 and Figure 4 A sealing tube 4 is provided on the sealing sleeve at one end of the movable tube 22 near the fixed tube 21, and the sealing tube 4 is in sealing contact with the outer wall of the clamping ring 31. A mounting platform 222 is fixedly provided on the movable tube 22, and the sealing tube 4 is connected to the mounting platform 222. A rubber ring 41 is provided between the sealing tube 4 and the side wall of the clamping ring 31.

[0042] Reference Figure 3 and Figure 4 The sealing tube 4 is connected with an air pipe 42, and an air bag 421 is sleeved on the air pipe 42. The air bag 421 is made of rubber. When the connection between the fixed tube 21 and the movable tube 22 is loose or the sealing ring 32 is damaged, the hot air in the movable tube 22 is usually discharged through the gap between the sealing ring 32 and the fixed tube 21, and then enters the sealing tube 4, and enters the air bag 421 through the air pipe 42, so that the air bag 421 expands. At this time, the maintenance personnel can easily determine the branch pipe 2 that has a leak, and there is no need to regularly inspect each branch pipe 2, thereby improving the efficiency and convenience of maintenance.

[0043] Reference Figure 3 and Figure 5 An inclined air guide plate 5 is provided at one end of the branch pipe 2 close to the heat dissipation air duct 12, one end of the air guide plate 5 extends into the heat dissipation air duct 12, and the air guide plate 5 is inclined toward the gas flow direction in the heat dissipation air duct 12, and the inclination direction of the air guide plate 5 forms an angle of 45 degrees with the heat dissipation air duct 12.

[0044] Reference Figure 3 and Figure 5 The air guide plate 5 is hinged in the fixed tube 21. An elastic member for driving the air guide plate 5 to deflect downward is arranged in the fixed tube 21. The elastic member is set as a torsion spring. A limit platform 211 is fixedly arranged in the fixed tube 21 along the circumference of the fixed tube 21. When the air guide plate 5 is in a closed state, that is, when the air guide plate 5 is deflected to a horizontal state, the bottom wall of the air guide plate 5 abuts against the limit plate, which plays a role in closing the branch pipe 2. At the same time, in order to further improve the sealing effect, an annular sealing ring 2111 is arranged on the limit platform 211, and the sealing ring abuts against the guide plate. Ear plates are fixedly arranged on both sides of the fixed tube 21. A hinge shaft 51 is rotatably arranged between the two ear plates. The air guide plate 5 is rotatably sleeved on the hinge shaft 51. The torsion spring is sleeved on the hinge shaft 51. One end of the torsion spring is fixedly connected to the ear plate, and the other end is fixedly connected to the air guide plate 5.

[0045] Reference Figure 3 and Figure 5A driving block 52 is fixedly provided on the top wall of the air guide plate 5, and a pull rope 521 is fixedly connected to the driving block 52. An opening is opened on the side wall of the fixed tube 21 for the pull rope 521 to pass through. A guide wheel 212 is rotatably provided on the outer wall of the fixed tube 21. The guide wheel 212 is located at the opening, and the pull rope 521 is wound around the guide wheel 212.

[0046] Reference Figure 3 and Figure 5 A sleeve 6 is fixedly provided on the side wall of the fixed tube 21 in the vertical direction, and a first damping platform 61 and a second damping platform 62 are slidably provided in the sleeve 6. There is a certain friction force between the sleeve 6 and the first damping platform 61 and the second damping platform 62, which plays a role in hindering sliding. A tension spring 63 is fixedly connected between the first damping platform 61 and the second damping platform 62.

[0047] Reference Figure 3 and Figure 5 An adjusting member for adjusting the length of the pull rope 521 is provided on the fixed tube 21, and the adjusting member is set as an adjusting bolt 64, and the adjusting bolt 64 is threadedly penetrated through the bottom wall of the sleeve 6, and the adjusting bolt 64 is rotatably connected to the second damping platform 62, and the adjusting bolt 64 and the second damping platform 62 are ball-connected.

[0048] When the airflow enters the heat dissipation duct 12 from the branch pipe 2, the airflow directly impacts the air guide plate 5, and at the same time, a part of the airflow in the heat dissipation duct 12 will also impact the air guide plate 5. Under the joint action of the two airflows, the air guide plate 5 will vibrate to a certain extent. During this process, the pull rope 521 is tightened or loosened, and at the same time, under the action of the tension spring 63, the first damping platform 61 and the second damping platform 62 slide in the sleeve 6. Under the action of friction, the first damping platform 61 and the second damping platform 62 convert the energy generated by the vibration into heat energy, thereby achieving the effect of shock absorption and energy dissipation, and reducing the vibration of the air guide plate 5; at the same time, due to the existence of the air guide plate 5, the energy of the two airflows is reduced, and the direct effect of the two airflows on the heat dissipation pipe is reduced, so as to prevent the heat dissipation pipe from vibrating, and prevent the heat dissipation pipe and the branch pipe 2 from loosening due to vibration.

[0049] Reference Figure 3 and Figure 5, a hanging rope 53 is fixedly connected to the air guide plate 5, and a damping ball 531 is fixedly connected to the hanging rope 53. If a certain distribution cabinet 11 is out of use or in the maintenance stage, the air guide plate 5 can be closed at this time, and the restriction of the pull rope 521 can be released. The air guide plate 5 is deflected in the horizontal direction under the tension of the elastic member and the damping ball 531 until the outlet of the branch pipe 2 at that location is completely closed, preventing the airflow in the heat dissipation air duct 12 from being discharged downward from the branch pipe 2 at that location. At the same time, during normal use, when the air guide plate 5 vibrates, it will drive the damping ball 531 to shake, and the damping ball 531 plays a role in hindering the vibration of the air guide plate 5, and plays a role in shock absorption and energy dissipation, effectively reducing the vibration amplitude of the air guide plate 5.

[0050] The implementation principle of the embodiment of the present invention is as follows: the heat dissipation fan 121 works so that the hot air generated by the several distribution cabinets 11 in the distribution room 1 is transported to the heat dissipation duct 12 through the corresponding branch pipe 2, and then discharged outside the distribution room 1 through the heat dissipation duct 12, so that the hot air generated by the distribution cabinet 11 does not need to directly exchange heat with the air in the distribution room 1, thereby reducing the power required for cooling the distribution room 1. In addition, the hot air entering the heat dissipation duct 12 from the branch pipe 2 is guided by the air guide plate 5, reducing the angle between the airflow direction in the branch pipe 2 and the airflow direction in the heat dissipation duct 12, thereby reducing the wind resistance in the process of the airflow entering the heat dissipation duct 12 from the branch pipe 2, thereby improving the heat dissipation efficiency.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
