Description

Technical Field

[0001] The utility model relates to the technical field of box-type substations, in particular to a heat dissipation device for internal modules of a box-type substation. Background Art

[0002] Currently, in box-type substations, modular design is reflected in the integration of different functional modules such as transformer switchgear, protection devices and control systems in a closed box. This design makes the box-type substation detachable, scalable and flexible in layout, and can be customized and adjusted according to different usage conditions and needs. At the same time, the modular design also facilitates the transportation, installation and maintenance of the box-type substation, and improves work efficiency and economic benefits.

[0003] A fully modularized small box-type substation is disclosed in the Chinese utility model patent with the announcement number CN212542965U. Although the above-mentioned prior art realizes large-scale production, low installation and operation costs, energy saving, consumption reduction and intelligence through a fully modularized design, the pursuit of a box-type modular design will make the internal electronic equipment very close together. This will result in the electronic equipment being unable to rely on spatial distance for heat dissipation after heating up. When the box-type substation module cannot effectively dissipate heat, hazards such as short circuits will occur, and may even cause fires. Therefore, it is necessary to design a heat dissipation device that can effectively dissipate heat from the internal modules of the box-type substation. Utility Model Content

[0004] In order to solve the technical problem that internal modules of a box-type substation are not easy to dissipate heat, the utility model provides a heat dissipation device for internal modules of a box-type substation.

[0005] The utility model is implemented by the following technical scheme: a box-type substation internal module heat dissipation device, including a module box with modules arranged inside, one side of the module box is provided with a gas exhaust component for discharging high-temperature air inside the module box, the other side of the module box is provided with a gas supply component for supplying external normal-temperature air into the module box for cooling and heat dissipation, one side of the module box is provided with multiple air outlets, the gas exhaust component includes a first mounting plate fixedly mounted on the module box on one side of the air outlet, multiple first rotating columns rotatably mounted on the first mounting plate and multiple exhaust fan blades fixedly mounted on each first rotating column.

[0006] Through the above technical solution, when the temperature inside the module box rises, the temperature sensor will send a signal to the controller, and the controller will control the servo motor to start. In this way, the gas discharge component and the gas supply component will be activated. One side of the module box will send external normal-temperature gas into the module box, and the other side will extract the high-temperature gas inside the module box, so that the air can flow inside the module box for heat dissipation. This setting can not only meet the requirements of the small size and compact modules of the box-type substation, but also avoid damage caused by the increase in the temperature of the modules inside the box-type substation.

[0007] As a further improvement of the above solution, an air inlet is provided on one side of the module box. The gas supply component includes a second mounting plate fixedly installed with the module box on one side of the air inlet, a second rotating column rotatably installed on the second mounting plate, and a plurality of air supply fan blades fixedly installed on the second rotating column.

[0008] Through the above technical solution, when the second rotating column rotates, the air supply fan blades will rotate, thereby sending external air into the module box.

[0009] As a further improvement of the above solution, both the first mounting plate and the second mounting plate are arranged in a "C" shape.

[0010] Through the above technical solution, the first mounting plate and the second mounting plate can facilitate the installation of the rotating column and the fan blades.

[0011] As a further improvement of the above solution, fixing plates are fixedly installed on both sides of the first mounting plate. A rotating shaft is rotatably installed between the two fixing plates. One end of each first rotating column is fixedly installed with a first bevel gear. A second bevel gear is meshed and connected to one side of each first bevel gear. Each second bevel gear is fixedly sleeved on the rotating shaft.

[0012] Through the above technical solution, when the rotating shaft rotates, the second bevel gear will drive the first bevel gear, thereby making the exhaust fan blades rotate to exhaust air.

[0013] As a further improvement of the above solution, a servo motor is provided on one side of the first mounting plate. One end of the rotating shaft penetrates through the adjacent fixing plate and is fixedly installed with the output end of the servo motor. Driving gears are fixedly sleeved on both the rotating shaft and the second rotating column. A synchronous belt for synchronous transmission is sleeved on the two driving gears.

[0014] Through the above technical solution, when the servo motor starts, the rotating shaft will rotate, so that both the exhaust fan blades and the air supply fan blades will rotate for synchronous operation.

[0015] As a further improvement of the above solution, a temperature sensor for monitoring temperature and sending signals is provided inside the module box, and a controller for receiving the temperature sensor signal and controlling the start and stop of the servo motor is provided on one side of the temperature sensor.

[0016] Through the above technical solution, the temperature sensor will send the sensed temperature signal to the controller, so that the controller can control the start and stop of the servo motor.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model sets a gas exhaust component and a gas supply component. When the temperature inside the module box rises, the temperature sensor will sense it and send a signal to the controller. The controller will control the servo motor to turn on, so that the gas exhaust component and the gas supply component will be started. One side of the module box will send the external normal temperature gas into the module box, and the other side will draw the high-temperature gas inside the module box out of the module box, so that the air can flow inside the module box to dissipate heat. This arrangement can not only meet the small size and compact modules of the box-type substation, but also avoid damage caused by the temperature increase of the internal modules of the box-type substation.

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figure 1-Figure 3, A heat dissipation device for internal modules of a box-type substation in this embodiment includes a module box 1 with modules inside. On one side of the module box 1, there is a gas discharge component for discharging the high-temperature air inside the module box 1. On the other side of the module box 1, there is a gas intake component for sending external normal-temperature air into the module box 1 for cooling and heat dissipation. A plurality of air outlets are provided on one side of the module box 1. The gas discharge component includes a first mounting plate 201 fixedly installed on the module box 1 on one side of the air outlet, a plurality of first rotating columns 202 rotatably installed on the first mounting plate 201, and a plurality of exhaust fan blades 203 fixedly installed on each first rotating column 202. An air inlet is provided on one side of the module box 1. The gas intake component includes a second mounting plate 301 fixedly installed on the module box 1 on one side of the air inlet, a second rotating column 302 rotatably installed on the second mounting plate 301, and a plurality of air supply fan blades 303 fixedly installed on the second rotating column 302. Both the first mounting plate 201 and the second mounting plate 301 are arranged in a "C" shape. When the temperature inside the module box 1 rises, the gas discharge component and the gas intake component will be started. One side of the module box 1 will send external normal-temperature gas into the module box 1, and the other side will extract the high-temperature gas inside the module box 1 from the module box 1, so that the air flows inside the module box 1 for heat dissipation.

[0026] Combined with Figure 1-Figure 3 , Fixed plates 4 are fixedly installed on both sides of the first mounting plate 201. A rotating shaft 5 is rotatably installed between the two fixed plates 4. One end of each first rotating column 202 is fixedly installed with a first bevel gear 6. A second bevel gear 7 is meshed and connected to one side of each first bevel gear 6. Each second bevel gear 7 is fixedly sleeved on the rotating shaft 5. A servo motor 8 is provided on one side of the first mounting plate 201. One end of the rotating shaft 5 penetrates through the adjacent fixed plate 4 and is fixedly installed with the output end of the servo motor 8. Driving gears 9 are fixedly sleeved on both the rotating shaft 5 and the second rotating column 302. A synchronous belt 10 for synchronous transmission is sleeved on the two driving gears 9. A temperature sensor 11 for monitoring the temperature and sending signals is provided inside the module box 1. A controller 12 for receiving the signals of the temperature sensor 11 and controlling the start and stop of the servo motor 8 is provided on one side of the temperature sensor 11. When the servo motor 8 starts, the rotating shaft 5 will rotate, so that both the exhaust fan blades 203 and the air supply fan blades 303 will rotate for synchronous operation. The temperature sensor 11 will send the sensed temperature signal to the controller 12, so that the controller 12 can control the start and stop of the servo motor 8.

[0027] The implementation principle of a heat dissipation device for an internal module of a box-type substation in an embodiment of the present application is as follows: when the temperature of the internal module of the box-type substation rises due to long-term use, the temperature sensor 11 will sense the temperature increase and send a signal to the controller 12, and the controller 12 will turn on the servo motor 8, so that the rotating shaft 5 will rotate, and the second bevel gear 7 and the drive gear 9 on the rotating shaft 5 will rotate, so that the first bevel gear 6 and the other drive gear 9 will rotate, and finally the exhaust fan blades 203 and the supply fan blades 303 will rotate, so that the air inlet side of the module box 1 will allow the external normal temperature gas to be sent into the module box 1, and the air outlet side will draw the high-temperature gas inside the module box 1 out of the module box 1, so that the air flows inside the module box 1 to dissipate heat. This arrangement can not only meet the small size and compact modules of the box-type substation, but also avoid damage caused by the temperature increase of the internal modules of the box-type substation.
