Description

Technical Field

[0001] The present invention relates to the technical field of busbar protection cabinets, in particular to a busbar protection cabinet. Background Art

[0002] Many electrical devices in the power system are very sensitive to voltage drops. When the system experiences power fluctuations, the residual voltage on the busbar is instantaneously very low, which will cause these electrical devices to stop operating. When a short circuit occurs in the system, it is easy to cause power fluctuations in other connected electrical branches outside the short circuit line, which in turn causes the operation of important electrical devices in some branches that have not experienced short circuits to be interrupted, greatly reducing the reliability of power supply. Therefore, busbar protection cabinets are often installed in power systems to protect the normal operation of the busbar.

[0003] In the prior art, a busbar protection cabinet is often equipped with a large number of electrical components. During the operation of the protection cabinet, a large amount of heat is generated in the protection cabinet. In order to ensure the normal operation of the protection cabinet, the heat in the protection cabinet needs to be dissipated in time. The heat dissipation method of the existing protection cabinet is usually to set heat sinks or heat dissipation windows on the cabinet body. However, this heat dissipation method has poor heat dissipation effect when the temperature rises rapidly or at high temperatures, which easily leads to the possibility of fire in the protection cabinet due to excessive internal temperature. Summary of the Invention

[0004] The present application provides a busbar protection cabinet, which can quickly and effectively dissipate heat from the protection cabinet, thereby reducing the possibility of fire caused by excessive temperature in the protection cabinet.

The combination of blowing and exhausting can provide a more comprehensive heat dissipation effect for the cabinet, so that when the temperature in the cabinet rises rapidly and is too high, the heat can be dissipated in a timely and effective manner, reducing the possibility of fire due to excessive temperature in the cabinet.

[0008] By adopting the above technical solution, when the cabinet is dissipating heat, the pump is started to draw the gas from the external environment into the cooling pipe. When the gas flows in the cooling pipe, it will exchange heat with the coolant in the water tank to achieve cooling.

[0029] The present invention discloses a busbar protection cabinet, such as Figure 1 and Figure 2 As shown, the cabinet body 1 includes a cabinet door installed on the outer wall of the open side, and an exhaust pipe 2 connected to the cabinet body 1 is provided on the side wall of the cabinet body 1 on the side adjacent to the cabinet body 1.

[0030] When the temperature inside the cabinet 1 is too high and needs to be cooled, the fan motor 21 starts to drive the exhaust fan 23 to rotate, sucking the high-temperature gas inside the cabinet 1, causing the high-temperature gas to dissipate to the external environment through the exhaust pipe 2. The first filter 431 is set to block external dust and impurities, reducing the possibility of dust and impurities entering the cabinet 1 through the exhaust pipe 2 and interfering with electrical components.

[0031] like Figure 1 、 Figure 3 and Figure 4As shown, a blow pipe 3 is horizontally provided on the inner wall of the cabinet 1 on the side away from the exhaust pipe 2, and a plurality of nozzles 31 are horizontally provided on the outer wall of the blow pipe 3. The plurality of nozzles 31 are evenly spaced along the length direction of the blow pipe 3. An air delivery mechanism 4 is provided outside the cabinet 1 for blowing cold air into the blow pipe 3. The gas transmission mechanism 4 includes a water tank 41, a cooling pipe 43 and a pump body 42; the water tank 41 is fixedly connected to the bottom surface of the cabinet 1, and the water tank 41 contains coolant. The cooling pipe 43 is fixedly connected to the inner wall of the water tank 41 horizontally, and the cooling pipe 43 is spirally immersed in the coolant; the pump body 42 is installed on the outer wall of the cabinet 1, and the input end of the pump body 42 is fixedly connected to the air inlet pipe 421, and the end of the air inlet pipe 421 away from the pump body 42 is fixedly connected to the outlet end of the cooling pipe 43 and communicates with the cooling pipe 43; the output end of the pump body 42 is fixedly connected to the air outlet pipe 422, and the end of the air outlet pipe 422 away from the pump body 42 is fixedly connected to the outer wall of the blowing pipe 3 and communicates with the blowing pipe 3. The inlet end of the cooling pipe 43 is trumpet-shaped and extends to the outside of the water tank 41, and a first filter 431 is provided on the inner wall of the trumpet-shaped end of the cooling pipe 43.

[0032] When the heat inside the cabinet 1 is quickly dissipated, the pump body 42 is started to draw the gas from the external environment into the cooling pipe 43. The gas exchanges heat with the coolant in the cooling pipe 43 and is cooled down. The gas is then output to the blowing pipe 3 through the air inlet pipe 421 and the air outlet pipe 422. Finally, it is sprayed out through the nozzle 31 to blow air and dissipate heat to the components in the cabinet 1, causing the heat of the electrical components to dissipate into the environment for discharge. The first filter 431 is set to block dust and impurities, reducing the possibility of dust and impurities entering the cooling pipe 43.

[0033] like Figure 2 and Figure 3 As shown, a temperature sensor 14 for detecting the temperature of the inner wall of the cabinet 1 is installed on the inner wall of the top of the cabinet 1, and a controller 15 is provided on the top surface of the cabinet 1. The temperature sensor 14 is electrically connected to the input end of the controller 15, and the output end of the controller 15 is electrically connected to the fan motor 21 and the pump body 42. The controller 15 controls the operation of the fan motor 21 and the pump body 42.

[0034] The temperature sensor 14 can detect the temperature inside the cabinet 1 in real time and transmit the detection data to the controller 15. When the temperature inside the cabinet 1 is too high, the controller 15 will control the fan motor 21 and the pump body 42 to automatically start so that the heat inside the cabinet 1 can be dissipated in time.

[0035] like Figure 1 and Figure 3As shown, a first motor 11 is installed on the top surface of the cabinet 1, and a reciprocating screw 12 is coaxially fixed to the output end of the first motor 11 and extends vertically into the cabinet 1. A slider 13 is sleeved on the outside of the reciprocating screw 12 and is threadedly matched with the reciprocating screw 12. The slider 13 slides with the inner wall of the cabinet 1, and the blowing pipe 3 is horizontally fixed to the side wall of the slider 13.

[0036] When blowing cold air into the cabinet 1, the first motor 11 is started to drive the reciprocating screw 12 to rotate, prompting the slider 13 to drive the blowing pipe 3 to move back and forth in the vertical direction, so that the cold air blown by the nozzle 31 can fully contact the electrical components in the cabinet 1, thereby improving the cooling effect on the electrical components.

[0037] like Figure 1 、 Figure 3 and Figure 5 As shown, a plurality of semiconductor cooling fins 44 are provided on the outer wall of the water tank 41, a stirring shaft 45 is horizontally rotatably connected to the inner wall of the water tank 41, a stirring plate 451 is fixedly connected to the outer wall of the stirring shaft 45, the bottom end of the reciprocating screw 12 passes through the bottom wall of the cabinet 1 and the top wall of the water tank 41 and extends into the interior of the water tank 41, and a first transmission assembly 16 is provided at the bottom end of the reciprocating screw 12 to enable the reciprocating screw 12 to drive the stirring shaft 45 to rotate; The first transmission assembly 16 includes a first bevel gear 161 and a second bevel gear 162. The first bevel gear 161 is coaxially fixed to the outer wall of the bottom end of the reciprocating screw 12. The second bevel gear 162 is coaxially fixed to the outer wall of the end of the stirring shaft 45 close to the reciprocating screw 12. The second bevel gear 162 is meshed with the first bevel gear 161.

[0038] Under the meshing cooperation of the first bevel gear 161 and the second bevel gear 162, the reciprocating screw 12 will drive the stirring shaft 45 to rotate during the rotation process, prompting the stirring plate 451 to stir the coolant in the water tank 41, so that the coolant and the gas flowing in the cooling pipe 43 can fully exchange heat. The semiconductor refrigeration plate 44 arranged on the outer wall of the water tank 41 is used to cool the coolant after heat exchange, so as to ensure the cooling effect of the coolant on the gas.

[0039] like Figure 1 and Figure 6 As shown, a first cleaning brush 452 located outside the water tank 41 is fixedly connected to the end of the stirring shaft 45 close to the first filter 431 , and the first cleaning brush 452 can contact the outer surface of the first filter 431 .

[0040] During the rotation process, the stirring shaft 45 drives the first cleaning brush 452 to clean the outer surface of the first filter 431 to remove dust and impurities adhering to the outer surface of the first filter 431, thereby ensuring the air permeability of the first filter 431 to facilitate air intake.

[0041] like Figure 1 and Figure 6As shown, the cabinet body 1 is horizontally rotatably connected to the outer wall on the side where the exhaust pipe 2 is located with a rotating shaft 17 coaxial with the stirring shaft 45. A second cleaning brush 171 that can contact the outer surface of the second filter 24 is fixedly connected to the outer wall of the rotating shaft 17. A second transmission assembly 18 that can drive the rotating shaft 17 to rotate by the stirring shaft 45 is provided on the outer wall of the end of the stirring shaft 45 near the rotating shaft 17; The second transmission assembly 18 includes a first pulley 181, a second pulley 182 and a belt 183. The first pulley 181 is coaxially fixed to the outer wall of the end of the stirring shaft 45 close to the rotating shaft 17. The second pulley 182 is coaxially fixed to the outer wall of the rotating shaft 17. The belt 183 is tensioned and sleeved on the outside of the first pulley 181 and the second pulley 182. The belt 183 links the first pulley 181 and the second pulley 182.

[0042] During the rotation process, the stirring shaft 45 drives the rotating shaft 17 to rotate through the cooperation of the first pulley 181, the second pulley 182 and the belt 183, prompting the second cleaning brush 171 to clean the surface of the second filter 24, reducing the possibility of the second filter 24 being blocked by dust and impurities, and ensuring the air permeability of the second filter 24 to facilitate heat dissipation.

[0043] Working principle: The temperature sensor 14 provided in the cabinet 1 can detect the temperature in the cabinet 1 in real time and transmit the detection result to the controller 15 for processing and analysis. When the temperature in the cabinet 1 is high, the controller 15 controls the pump body 42 and the fan motor 21 to start. The pump body 42 draws the gas from the external environment into the cooling pipe 43. The gas exchanges heat with the coolant in the cooling pipe 43 and is then output to the blowing pipe 3. The gas is then sprayed through the nozzle 31 to blow air and dissipate heat to the components in the cabinet 1, thereby causing the heat of the electrical components to dissipate into the environment. The fan motor 21 drives the exhaust fan 23 to rotate, sucking and discharging the high-temperature gas in the cabinet 1 into the external environment, so as to achieve rapid heat dissipation inside the cabinet 1. When the nozzle 31 sprays cold air to cool the electrical components, the first motor 11 is started to drive the reciprocating screw 12 to rotate, causing the slider 13 to drive the spray pipe 3 to reciprocate in the vertical direction, so that the cold air sprayed by the nozzle 31 can fully contact the electrical components in the cabinet 1, thereby improving the cooling effect of the air blowing on the electrical components; During the rotation of the reciprocating screw 12, the stirring shaft 45 and the stirring plate 451 are driven to rotate through the first transmission assembly 16, prompting the stirring plate 451 to stir the coolant in the water tank 41, thereby promoting sufficient heat exchange between the coolant and the gas in the cooling pipe 43, thereby improving the cooling effect on the gas; During the rotation process, the stirring shaft 45 will drive the first cleaning brush 452 to clean the first filter 431. At the same time, it will drive the rotating shaft 17 to rotate through the second transmission assembly 18, prompting the second cleaning brush 171 to clean the surface of the second filter 24, thereby ensuring the air permeability of the first filter 431 and the second filter 24, and reducing the possibility of the mesh of the first filter 431 and the second filter 24 being blocked.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
