Description

Technical Field

[0001] The present application relates to the field of outdoor power equipment, and in particular to a cooling device for an outdoor substation. Background Art

[0002] At present, the substation serves as a power transformation device, and its function is to convert the high voltage sent by the high-voltage cable into a low voltage of 220V or 380V for output, and then transmit the three-phase alternating current after the voltage reduction to the residential areas, high-rise buildings, factories and other electricity-consuming buildings in the rear.

[0003] In order to facilitate maintenance, installation and safety, outdoor substations are usually used as transformer equipment. Outdoor substations are usually designed and assembled in factories, and various electrical components such as high-voltage equipment, transformers, low-voltage equipment, and power distribution devices are then transported to the installation site. The outdoor substations are installed and debugged by the corresponding on-site installation personnel.

[0004] Regarding the above-mentioned related technologies, since part of the energy will be lost when high voltage electricity is converted into low voltage electricity, this part of the lost energy will be dissipated in the form of heat, and then accumulated and accumulated inside the outdoor substation. When the weather is relatively hot, it will further affect the heat dissipation of the outdoor substation, and finally cause excessive heat accumulation and affect the equipment safety and normal operation of the outdoor substation. Utility Model Content

[0005] In order to dissipate heat inside an outdoor substation and thereby reduce damage to equipment due to heat dissipation, the present application provides an outdoor substation cooling device.

[0006] The present application provides an outdoor substation cooling device, which adopts the following technical solution:

[0007] A cooling device for an outdoor substation comprises a housing, an electrical component is arranged inside the housing, a rainwater pan is arranged on the top of the housing, a delivery pipeline is arranged at the bottom of the rainwater pan, a cooling pipeline is arranged outside the electrical component, a water tank is arranged below the cooling pipeline, and the upper end surface of the water tank is fixedly connected to the lower end of the cooling pipeline.

[0008] By adopting the above technical solution, when it rains, the rainwater pan will collect rainwater, and send the collected rainwater along the delivery pipeline and the cooling pipeline to the water tank below in sequence, and the electrical components will be cooled when passing through the cooling pipeline. When the weather is hot and the temperature is too high, the rainwater stored in the water tank absorbs the heat inside the room and evaporates, and finally brings the heat out of the room along the cooling pipeline, effectively realizing the cooling and heat dissipation of the components inside the room.

[0009] Optionally, a bypass pipeline and a temperature sensor are provided inside the room, one end of the bypass pipeline is connected to the side of the delivery pipeline close to the delivery pipeline, the other end of the bypass pipeline is connected to the water tank, and a water pump is provided between the bypass pipeline and the water tank.

[0010] By adopting the above technical solution, when the temperature inside the room is high, the water pump starts to pump the water inside the water tank into the delivery pipeline through the bypass pipeline. At this time, the water will pass through the cooling pipeline and the electrical components again. As the rainwater passes by, the electrical components are effectively cooled.

[0011] Optionally, a baffle is provided between the rainwater pan and the delivery pipeline, the baffle is provided with an abutment portion, the abutment portion extends to the outside of the delivery pipeline, the baffle is rotatably connected to the delivery pipeline, a float is provided in the water tank, the float is provided with a top rod, the top rod is provided with an upwardly extending, the water tank is provided with an avoidance groove for avoiding the top rod, the upper end of the top rod abuts against the abutment portion, the baffle is provided with a drainage groove, and a drainage pipe extending to the outside of the house is provided at the end of the drainage groove.

[0012] By adopting the above technical solution, as the rainwater level inside the water tank rises, the float also rises with the water level, thereby driving the top rod to move upward, and the top rod abuts against the abutting part of the baffle. As the water level rises, the baffle gradually closes the delivery pipeline. When the water level reaches the upper limit, the baffle closes the entire delivery pipeline. At this time, rainwater entering the water delivery pipeline can only be discharged through the drain trough and the drain pipe, which effectively prevents rainwater exceeding the volume of the water tank from entering the room, and effectively prevents excessive rainwater from accumulating in the rainwater tray and the delivery pipeline to cause damage to the device.

[0013] Optionally, a control module is provided inside the room body, the water tank is provided with a contact sensor for detecting the minimum water level, a motor is provided inside the room body, the motor is provided with an eccentric wheel, the eccentric wheel is located on the upper side of the abutting part, the eccentric wheel sleeve is provided with a pull rope, and the side of the pull rope away from the signal wheel abuts against the lower end surface of the abutting part.

[0014] By adopting the above technical solution, when the internal temperature continues to be too high and the float hits the contact sensor as the water level drops, the motor rotates to drive the eccentric wheel to rotate. As the eccentric wheel rotates, the pull rope pulls the abutment part upward to close the delivery pipeline. At this time, the water stored in the water tank can also circulate internally between the cooling pipeline and the water tank. When the temperature drops, the motor continues to rotate and the lowest end of the pull rope and the abutment part move downward at the same time to open the delivery pipeline, effectively allowing the water tank and the cooling pipeline to maintain a certain heat dissipation capacity in a long-term high temperature environment without rainfall.

[0015] Optionally, an anti-condensation controller is provided on the inner wall of the room, a ventilation grille is provided on the horizontal side of the room, an exhaust fan is provided inside the room, and an air outlet of the exhaust fan points to the ventilation grille.

[0016] By adopting the above technical solution, the anti-condensation controller detects and controls the humidity level inside the room. When the internal humidity is too high, the exhaust fan discharges the humid air inside the room to the outside of the room, and the air is discharged from the room through the ventilation grille, effectively realizing the detection and control of the humidity inside the room.

[0017] Optionally, vertical cooling fins are provided inside the room body, the cooling fins are provided with a water inlet and a water outlet, the water pump is provided with an electromagnetic three-way valve, the electromagnetic three-way valve is used to connect the water pump, the bypass pipeline and the water inlet, a return pipeline is provided between the water outlet of the cooling fins and the water tank, and the cooling fins are located between the exhaust fan and the ventilation grille.

[0018] By adopting the above technical solution, when the internal temperature continues to be too high and the float touches the contact sensor, the electromagnetic three-way valve opens, and the water pump pumps the water in the water tank into the bypass pipe and the cooling fins at the same time. When the water with higher temperature passes through the cooling fins, the exhaust fan turns on at the same time to cool down the cooling fins and dissipate the heat, and the air with higher temperature after passing through the cooling fins is discharged from the room through the ventilation grille, effectively cooling the water inside the water tank to improve the heat exchange and heat dissipation efficiency.

[0019] Optionally, the water tank is provided with a first flange, the cooling pipeline is provided with a first flange adapted to the first flange, a filter is provided between the first flange and the second flange, and the water tank is provided with a clamp for locking the first flange and the second flange.

[0020] By adopting the above technical solution, the filter will intercept impurities from the outside, making it difficult for the impurities to enter the water tank. When it is necessary to clean the impurities accumulated on the filter, the operator will open the clamp, clean the impurities on the filter out of the cooling pipeline, and replace the filter with a new one, which effectively isolates impurities from the outside and facilitates the operator to replace the filter.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When it rains, the rainwater pan collects rainwater and sends it to the water tank below along the delivery pipeline and cooling pipeline in sequence. When passing through the cooling pipeline, the electrical components are cooled down. When the weather is hot and the temperature is too high, the rainwater stored in the water tank absorbs the heat inside the room and evaporates, and finally takes the heat out of the room along the cooling pipeline, effectively realizing the cooling and heat dissipation of the components inside the room.

[0023] 2. When the temperature inside the room is high, the water pump starts to pump the water inside the water tank into the delivery pipeline through the bypass pipeline. At this time, the water will pass through the cooling pipeline and the electrical components again. As the rainwater passes by, the electrical components are effectively cooled.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] An embodiment of the present application discloses an outdoor substation cooling device.

[0033] Reference Figures 1 to 6 A cooling device for an outdoor substation includes a housing 1, an electrical component 13 is arranged inside the housing 1, a rainwater pan 11 is arranged on the top of the housing 1, a delivery pipeline 141 is arranged at the bottom of the rainwater pan 11, a cooling pipeline 14 is arranged outside the electrical component 13, a water tank 12 is arranged below the cooling pipeline 14, and the upper end surface of the water tank 12 is fixedly connected to the lower end of the cooling pipeline 14. When it rains, the rainwater pan 11 collects rainwater, and sends the collected rainwater to the inside of the water tank 12 below along the delivery pipeline 141 and the cooling pipeline 14 in sequence, and completes cooling of the electrical component 13 when passing through the cooling pipeline 14. When the weather is hot and the temperature is too high, the rainwater stored in the water tank 12 absorbs the heat inside the housing 1 and evaporates, and finally takes the heat out of the housing 1 along the cooling pipeline 14 and the delivery pipeline 141, thereby achieving cooling and heat dissipation of the components inside the housing 1.

[0034] In order to further improve the utilization rate of the water stored in the water tank 12, the electrical components are cooled again by the water in the water tank 12. A bypass pipeline 2 and a temperature sensor 16 are provided inside the room body 1. One end of the bypass pipeline 2 is connected to the side of the delivery pipeline 141 close to the delivery pipeline 141, and the other end of the bypass pipeline 2 is connected to the water tank 12. A water pump 21 is provided between the bypass pipeline 2 and the water tank 12. When the temperature inside the room body 1 is high, the water pump 21 starts to pump the water inside the water tank 12 into the delivery pipeline 141 through the bypass pipeline 2. At this time, the water will pass through the cooling pipeline 14 and the electrical components 13 again, and the electrical components 13 will be cooled again as the rain passes.

[0035] Since it generally rains more in summer, in order to avoid excessive rainwater from accumulating inside the cooling pipe 14 for a long time as much as possible, a baffle 3 is provided between the rainwater tray 11 and the delivery pipe 141, and the baffle 3 is provided with an abutment portion 31, which extends to the outside of the delivery pipe. The baffle 3 is rotatably connected to the delivery pipe 141, and a float 121 is provided in the water tank 12, and the float 121 is provided with a top rod 122, and the top rod 122 is provided with an upward extension. The water tank 12 is provided with an avoidance groove for avoiding the top rod 122, and the upper end of the top rod 122 abuts against the abutment portion 31, and the baffle 3 is provided with a drainage groove 32, and a drainage pipe 33 extending to the outside of the room body 1 is provided at the end of the drainage groove 32. As the rainwater level inside the water tank 12 rises, the float 121 also rises with the water level, thereby driving the top rod 122 to move upward, and the top rod 122 abuts against the abutment portion 31 of the baffle 3. As the water level rises, the baffle 3 gradually closes the delivery pipeline 141. When the water level reaches the upper limit, the baffle 3 closes the entire delivery pipeline 141. At this time, rainwater entering the water delivery pipeline can only be discharged through the drain trough 32 and the drain pipe 33, avoiding rainwater exceeding the volume of the water tank 12 from entering the interior of the house 1, and preventing excessive rainwater from accumulating in the rainwater pan 11 and the delivery pipeline to cause damage to the device.

[0036] When the temperature rises after rainfall and needs to be cooled again, the water pump 21 pumps the water in the water tank 12 into the cooling pipeline 14 through the bypass pipeline 2. At this time, the water level drops and the baffle 3 opens again. At this time, the water in the water tank 12 and the cooling pipeline 14 will take away the heat of the room 1 by evaporation again, and the water vapor will be discharged from the interior of the room 1 through the delivery pipeline 141.

[0037] When the temperature in the room is continuously too high, the water in the water tank 12 will evaporate quickly. In order to retain the water in the water tank 12 and circulate the water in the device, a control module 15 is provided inside the room body 1, and the water tank 12 is provided with a contact sensor 123 for detecting the lowest water level. A motor 5 is provided inside the room body 1, and the motor 5 is provided with an eccentric wheel 51. The eccentric wheel 51 is located on the upper side of the abutment part 31, and the eccentric wheel 51 is sleeved with a pull rope 52. The side of the pull rope 52 away from the product signal wheel abuts against the lower end surface of the abutment part 31. When the internal temperature continues to be too high and the float 121 hits the contact sensor 123 as the water level drops, the motor 5 rotates to drive the eccentric wheel 51 to rotate. As the eccentric wheel 51 rotates, the pull rope 52 pulls the abutment part 31 upward to close the delivery pipeline 141. At this time, the water stored in the water tank 12 can still circulate internally between the cooling pipeline 14 and the water tank 12. When the temperature drops, the motor 5 continues to rotate and the lowest end of the pull rope 52 moves downward together with the abutment part 31 to open the delivery pipeline, so that the water tank 12 and the cooling pipeline 14 can still maintain a certain heat dissipation capacity in a long-term high temperature environment without rainfall.

[0038] In order to effectively control the humidity inside the room body 1 and reduce the influence of moisture in the air on the electrical components 13, an anti-condensation controller 17 is provided on the inner wall of the room body 1, a ventilation grille 4 is provided on the horizontal side of the room body 1, and an exhaust fan 41 is provided inside the room body 1, and the air outlet of the exhaust fan 41 points to the ventilation grille 4. The anti-condensation controller 17 detects and controls the humidity inside the room body 1. When the internal humidity is too high, the exhaust fan 41 discharges the humid air inside the room body 1 to the outside of the room body 1, and the air is discharged from the room body 1 through the ventilation grille 4, thereby realizing the detection and control of the humidity inside the room body 1.

[0039] When the temperature is continuously too high and the water level is low, the baffle 3 blocks the delivery pipeline 141, and the water in the water tank 12 will enter the internal circulation, in order to further reduce the temperature of the water in the water tank 12 during the internal circulation. A vertical heat sink fin 42 is provided inside the room body 1, and the heat sink fin 42 is provided with a water inlet and a water outlet. The water pump 21 is provided with an electromagnetic three-way valve 22, and the electromagnetic three-way valve 22 is connected to the water pump 21, the bypass pipeline 2 and the water inlet. A reflux pipeline is provided between the outlet of the heat sink fin 42 and the water tank 12, and the heat sink fin 42 is located between the exhaust fan 41 and the ventilation grille 4. When the internal temperature continues to be too high and the float 121 hits the contact sensor 123, the electromagnetic three-way valve 22 opens, and the water pump 21 simultaneously pumps the water in the water tank 12 into the bypass pipe 2 and the cooling fins 42. When the higher temperature water passes through the cooling fins 42, the exhaust fan 41 is turned on at the same time to cool down the cooling fins 42 and dissipate the heat, and the higher temperature air after passing through the cooling fins 42 is discharged from the room 1 through the ventilation grille 4, effectively cooling the water inside the water tank 12 to improve the heat exchange and heat dissipation efficiency.

[0040] The water tank 12 is provided with a first flange, the cooling pipeline 14 is provided with a first flange adapted to the first flange, a filter is provided between the first flange and the second flange, and the water tank 12 is provided with a clamp 142 for locking the first flange and the second flange. The filter intercepts impurities from the outside, making it difficult for the impurities to enter the inside of the water tank 12. When it is necessary to clean the impurities accumulated at the filter, the operator opens the clamp 142, cleans the impurities on the filter out of the cooling pipeline 14, and replaces a new filter, which is convenient for isolating impurities from the outside and for the operator to replace the filter.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
