Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to an indoor power distribution cabinet for power engineering with good heat dissipation effect. Background Art

[0002] The technology of power distribution cabinets is an important field in the power system. Power distribution cabinets usually consist of a cabinet body, a circuit breaker, a disconnector, an instrument transformer, a watt-hour meter, etc. The cabinet body is the basis of the power distribution cabinet, used for installing electrical components and protecting the interior of the equipment. The electrical principle of the power distribution cabinet mainly involves the measurement and control of parameters such as current, voltage, and power factor. By using equipment such as instrument transformers, ammeters, and voltmeters, these electrical parameters can be monitored in real time and adjusted and controlled as needed. In power engineering, power distribution cabinets are widely used. They are installed in various power facilities such as substations, power plants, and industrial factories to distribute electric energy to each electrical equipment. At the same time, power distribution cabinets also undertake important tasks such as protecting the circuit and preventing the spread of electrical faults.

[0003] The electrical components in the power engineering power distribution cabinet generate heat during operation. If too much heat accumulates, it will lead to a decline in component performance or even damage. Therefore, we propose an indoor power distribution cabinet for power engineering with good heat dissipation effect. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an indoor power distribution cabinet for power engineering with good heat dissipation effect, including a cabinet body. One side of the cabinet body is fixedly connected with a hinge, and the side of the hinge away from the cabinet body is fixedly connected with a cabinet door. The bottom of the cabinet body is fixedly connected with cabinet legs. Rectangular holes I are opened on both sides of the cabinet body, and a heat dissipation device is fixedly connected to the inner wall of the rectangular hole I. Rectangular holes II are opened on both sides of the cabinet body, and a ventilation device is fixedly connected to the inner wall of the rectangular hole II. A round hole is opened on the outer surface of the cabinet body, and a water-cooling heat dissipation device is fixedly connected to the inner wall of the cabinet body. One side of the heat dissipation device is fixedly connected to the inner wall of the cabinet body, one side of the ventilation device is fixedly connected to the outer surface of the cabinet body, and the outer surface of the water-cooling heat dissipation device is fixedly connected to the inner wall of the round hole.

[0005] The heat dissipation device includes a rectangular frame. One side of the rectangular frame is fixedly connected with a protective cover. The inner wall of the protective cover is fixedly connected with a motor. The driving shaft of the motor is fixedly connected with a first fixed rod. The outer surface of the first fixed rod is sleeved and fixedly connected with a driving gear. One end of the first fixed rod away from the motor is fixedly connected with a first rotating plate. One side of the rectangular frame penetrates and is rotatably connected with a second fixed rod. One end of the second fixed rod penetrates and is fixedly connected with a driven gear. One end of the second fixed rod away from the driven gear is fixedly connected with a second rotating plate. According to the different degrees of heat generation of the power components, the motor drives the driving gear to rotate. The teeth of the driving gear mesh with the teeth of the driven gear, thereby driving the driven gear to rotate. The first rotating plate and the second rotating plate fixedly connected thereto rotate accordingly, adjusting the wind direction and blowing the air flow to the position with a strong heat generation degree. The air flow blows through the power components, taking away the generated heat, improving the heat dissipation effect, and preventing the part with a high heat generation degree from having a low heat dissipation effect. The inner wall of the rectangular frame is fixedly connected with a rectangular rod. One end of the rectangular rod away from the rectangular frame is fixedly connected with a sleeve. The inner wall of the sleeve is fixedly connected with a motor. The driving shaft of the motor is fixedly connected with a round rod. The outer surface of the round rod is sleeved and fixedly connected with a sleeve block. The outer surface of the sleeve block is fixedly connected with fan blades. By driving the round rod to rotate through the motor, the fan blades are driven to rotate accordingly. The rotation of the fan blades generates an air flow, sucking the external air into the cabinet interior and taking away the heat generated on the surface of the power components, greatly improving the heat dissipation efficiency and ensuring that the power components can operate at a safe temperature. The outer surface of the round rod is fixedly connected with a scraping rod. The scraping rod rotates together with the round rod, continuously cleaning the dust and solid particles on the surface of the filter plate, effectively avoiding the problem that the heat dissipation efficiency is reduced due to the blockage of the filter plate. The inner wall of the rectangular frame is fixedly connected with a filter plate. When the filter plate sucks in the air rotated by the fan blades, the dust and other particles carried in the air are isolated outside, preventing them from entering the cabinet interior and causing pollution to the power components or affecting the heat dissipation effect. The outer surface of the rectangular frame is fixedly connected with the inner wall of the first rectangular hole. One side of the protective cover is fixedly connected with the inner wall of the cabinet. One end of the first fixed rod away from the motor penetrates the rectangular frame and is rotatably connected with the rectangular frame. One side of the first rotating plate away from the first fixed rod is rotatably connected with the inner wall of the rectangular frame through a rotating bolt. One side of the second rotating plate away from the second fixed rod is rotatably connected with the inner wall of the rectangular frame through a rotating bolt. One end of the round rod away from the motor penetrates the filter plate and is rotatably connected with the filter plate.

[0006] Further, the ventilation device includes a breathable plate, and air flows through the breathable plate to the outside of the cabinet body to ensure that the hot air inside the cabinet body can be effectively discharged. One side of the breathable plate is fixedly connected with a gas guide plate. A rectangular groove is formed on the side of the gas guide plate away from the breathable plate. One side of the gas guide plate is fixedly connected with a servo motor, and the drive shaft of the servo motor is fixedly connected with a rotating guide plate. According to the guiding direction of the air flow, the drive shaft of the servo motor rotates to drive the rotating guide plate to rotate, and the air flow is discharged from the cabinet body through the breathable plate, so that the rotating guide plate can flexibly adjust the angle as needed, thereby guiding the air flow to be discharged from the cabinet body through the breathable plate, improving the heat dissipation efficiency, and also ensuring the controllability of the air flow discharge direction, avoiding the problem of uneven heat dissipation caused by air flow disorder. One side of the breathable plate away from the gas guide plate is fixedly connected with a dust-proof cover. The dust-proof cover prevents these particles scraped off by the scraping rod from re-entering the cabinet body and causing pollution to the power components or affecting the heat dissipation effect. The inner wall of the dust-proof cover is fixedly connected with a filter screen. The small mesh holes of the filter screen ensure the smooth passage of the air flow and effectively intercept impurities. The outer surface of the breathable plate is fixedly connected with the inner wall of the second rectangular hole. The side of the rotating guide plate away from the servo motor is rotatably connected with the inner wall of the rectangular groove through a rotating bolt. The side of the filter screen away from the dust-proof cover is fixedly connected with the side of the breathable plate away from the gas guide plate.

[0007] Furthermore, the water-cooling and heat-dissipating device includes a water tank. A cooling pipe is fixedly connected to the inner wall of the water tank, and liquid nitrogen is contained inside the cooling pipe. After the water flow flows out from the water-passing plate and returns to the water tank, it is cooled by the cooling pipe inside the water tank to keep the water temperature low and continue water-cooling and heat-dissipating, preventing the heat-dissipating effect from decreasing. One side of the water tank is communicated with a first water pipe. The end of the first water pipe far away from the water tank is communicated with a water pump. One side of the water tank close to the first water pipe is communicated with a second water pipe. The end of the second water pipe far away from the water tank is communicated with a water-passing plate. A tubular through-hole is formed on one side of the water-passing plate. The water pump pumps the water in the water tank into the water-passing plate through the second water pipe. The water flow takes away the heat generated by the power components installed on the surface of the water-passing plate through the tubular through-hole, effectively reducing the temperature of the power components and ensuring safe operation. The inner wall of the tubular through-hole is rotationally connected to a short round rod through a rotating bolt. A rectangular plate is fixedly connected to the outer surface of the short round rod. When the water flow passes through the rectangular plate, it is blocked and the flow rate slows down, thereby increasing the contact time between the water flow and the power components and the heat exchange area, making the heat exchange more thorough and further improving the heat-dissipating effect. A three-way pipe is communicated with the side of the water tank far away from the first water pipe. The top of the three-way pipe is threadedly connected with a water inlet cover, and the bottom of the three-way pipe is threadedly connected with a water outlet cover. After long-term use, the internal water flow needs to be replaced. Open the water outlet cover to let the water flow out. After the internal water flow is exhausted, close the water outlet cover and open the water inlet cover to pour water in to ensure the cleanliness of the internal water flow and clean the pipeline at the same time. The side of the water tank far away from the first water pipe is fixedly connected to the inner wall of the cabinet body. The side of the water-passing plate is fixedly connected to the inner wall of the cabinet body. The outer surface of the three-way pipe is fixedly connected to the inner wall of the round hole. Multiple rectangular plates are provided, and the multiple rectangular plates are distributed on the outer surface of the short round rod.

[0008] The beneficial effects of the present invention are as follows:

[0009] 1. In the present invention, the motor drives the round rod to rotate, and then drives the fan blades to rotate. The rotating fan blades generate an air flow, sucking the external air into the cabinet body and taking away the heat generated on the surface of the power components, greatly improving the heat-dissipating efficiency and ensuring that the power components can operate at a safe temperature. When the filter plate sucks in the air rotated by the fan blades, the dust and other particles carried in the air are isolated outside, preventing them from entering the cabinet body and causing pollution to the power components or affecting the heat-dissipating effect. The air flow flows through the air-permeable plate and flows out of the cabinet body, ensuring that the hot air inside the cabinet body can be effectively discharged. According to the guiding direction of the air flow, the driving shaft of the servo motor rotates to drive the rotating guide plate to rotate, discharging the air flow through the air-permeable plate out of the cabinet body, enabling the rotating guide plate to flexibly adjust the angle as needed, thereby guiding the air flow to be discharged through the air-permeable plate out of the cabinet body and improving the heat-dissipating efficiency. The water pump pumps the water in the water tank into the water-passing plate through the second water pipe. The water flow takes away the heat generated by the power components installed on the surface of the water-passing plate through the tubular through-hole.

[0010] 2. The present invention improves the heat dissipation efficiency by a large margin and ensures the operation of power components at a safe temperature by setting up a heat dissipation device. The motor drives the round rod to rotate, which in turn drives the fan blades to rotate. The rotation of the fan blades generates an air current that sucks external air into the cabinet interior and takes away the heat generated on the surface of the power components. When the filter plate sucks in the air rotated by the fan blades, it isolates the dust and other particles carried in the air outside, preventing them from entering the cabinet interior to contaminate the power components or affect the heat dissipation effect. At the same time, the scraping rod rotates together with the round rod to continuously clean the dust and solid particles on the surface of the filter plate, effectively avoiding the problem of reduced heat dissipation efficiency caused by the blockage of the filter plate. According to the different heating degrees of the power components, the motor drives the driving gear to rotate. The teeth of the driving gear mesh with the teeth of the driven gear, thereby driving the driven gear to rotate. The rotating plates I and II fixedly connected thereto rotate accordingly to adjust the wind direction and blow the air current to the position with a strong heating degree. The air current blows over the power components and takes away the generated heat, improving the heat dissipation effect and preventing the low heat dissipation effect of the part with a high heating degree.

[0011] 3. The present invention ensures the effective discharge of the hot air inside the cabinet by setting up a ventilation device. The air current flows through the breathable plate to the outside of the cabinet. According to the guiding direction of the air current, the driving shaft of the servo motor rotates to drive the rotating guide plate to rotate, and discharges the air current through the breathable plate from the cabinet, enabling the rotating guide plate to flexibly adjust the angle as needed, thereby guiding the air current to be discharged from the cabinet through the breathable plate, improving the heat dissipation efficiency and also ensuring the controllability of the discharge direction of the air current, avoiding the problem of uneven heat dissipation caused by the disorder of the air current. The dust-proof cover prevents these particles scraped off by the scraping rod from re-entering the cabinet interior to contaminate the power components or affect the heat dissipation effect. The mesh holes of the filter net are small, which not only ensures the smooth passage of the air current but also effectively intercepts impurities.

[0012] 4. The present invention effectively reduces the temperature of the power components and ensures the safe operation by setting up a water-cooled heat dissipation device. The water pump extracts the water in the water tank and enters the water-through plate through the second water pipe. The water flow takes away the heat generated by the power components installed on the surface of the water-through plate through the tubular through holes, effectively reducing the temperature of the power components. When the water flow passes through the rectangular plate, it is blocked and the flow rate slows down, thereby increasing the contact time between the water flow and the power components and the heat exchange area, making the heat exchange more thorough and further improving the heat dissipation effect. Liquid nitrogen is installed inside the cooling pipe. After the water flow flows out of the water-through plate and returns to the water tank, it is cooled through the cooling pipe inside the water tank to continue the water-cooled heat dissipation and prevent the reduction of the heat dissipation effect. After long-term use, the internal water flow needs to be replaced. Open the water outlet cover to let the water flow out. After the internal water flow is exhausted, close the water outlet cover. Open the water inlet cover and pour in water to ensure the cleanliness of the internal water flow and clean the pipeline at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The heat dissipation device 6 includes a rectangular frame 601. One side of the rectangular frame 601 is fixedly connected with a protective cover 602. The inner wall of the protective cover 602 is fixedly connected with a motor 603. The driving shaft of the motor 603 is fixedly connected with a first fixing rod 604. An outer surface of the first fixing rod 604 is sleeved and fixedly connected with a driving gear 605. One end of the first fixing rod 604 away from the motor 603 is fixedly connected with a first rotating plate 606. One side of the rectangular frame 601 is penetrated and rotatably connected with a second fixing rod 607. One end of the second fixing rod 607 is penetrated and fixedly connected with a driven gear 608. One end of the second fixing rod 607 away from the driven gear 608 is fixedly connected with a second rotating plate 609. The inner wall of the rectangular frame 601 is fixedly connected with a rectangular rod 610.

The driving shaft of the motor 612 is fixedly connected with a round rod 613. An outer surface of the round rod 613 is sleeved and fixedly connected with a sleeve block 614. An outer surface of the sleeve block 614 is fixedly connected with a fan blade 615. An outer surface of the round rod 613 is fixedly connected with a scraping rod 616. The inner wall of the rectangular frame 601 is fixedly connected with a filter plate 617.

When in use, the power components inside the cabinet body 1 are installed on the surface of the water-cooled heat dissipation device 10.

The filter plate 617 isolates the dust and other particles carried in the air when the fan blade 615 rotates and sucks in the air. At the same time, the scraping rod 616 rotates together with the round rod 613 to clean the filter plate 617 to prevent too much dust and other solid particles from adhering to the surface of the filter plate 617 during heat dissipation, which may hinder heat dissipation. According to the different degrees of heat generation at the heat generation positions of the power components,The operation of the motor 603 drives the rotation of the driving gear 605. The teeth of the driving gear 605 mesh with the teeth of the driven gear 608, thereby driving the rotation of the driven gear 608.

The air flow blows over the power components and takes away the generated heat.

[0028] For the second embodiment, please refer to Figures 1 - 11 The present invention provides an indoor power distribution cabinet for power engineering with good heat dissipation effect: The ventilation device 8 includes a ventilation plate 801. One side of the ventilation plate 801 is fixedly connected with a gas guide plate 802. A rectangular groove 803 is formed on the side of the gas guide plate 802 away from the ventilation plate 801. One side of the gas guide plate 802 is fixedly connected with a servo motor 804. The driving shaft of the servo motor 804 is fixedly connected with a rotating guide plate 805. A dust-proof cover 806 is fixedly connected to the side of the ventilation plate 801 away from the gas guide plate 802. A filter screen 807 is fixedly connected to the inner wall of the dust-proof cover 806. The outer surface of the ventilation plate 801 is fixedly connected with the inner wall of the rectangular hole two 7. The side of the rotating guide plate 805 away from the servo motor 804 is rotatably connected with the inner wall of the rectangular groove 803 through a rotating bolt. The side of the filter screen 807 away from the dust-proof cover 806 is fixedly connected with the side of the ventilation plate 801 away from the gas guide plate 802;

[0029] The water-cooling device 10 includes a water tank 1001. The inner wall of the water tank 1001 is fixedly connected with a cooling pipe 1002. One side of the water tank 1001 is communicated with a first water pipe 1003. The end of the first water pipe 1003 away from the water tank 1001 is communicated with a water pump 1004. One side of the water tank 1001 close to the first water pipe 1003 is communicated with a second water pipe 1005. The end of the second water pipe 1005 away from the water tank 1001 is communicated with a water-permeable plate 1006. A tubular through-hole 1007 is formed on one side of the water-permeable plate 1006. The inner wall of the tubular through-hole 1007 is rotationally connected with a short round rod 1008 through a rotating bolt. A rectangular plate 1009 is fixedly connected to the outer surface of the short round rod 1008. One side of the water tank 1001 away from the first water pipe 1003 is communicated with a three-way pipe 1010. The top of the three-way pipe 1010 is threadedly connected with a water inlet cover 1011. The bottom of the three-way pipe 1010 is threadedly connected with a water outlet cover 1012. One side of the water tank 1001 away from the first water pipe 1003 is fixedly connected to the inner wall of the cabinet 1. One side of the water-permeable plate 1006 is fixedly connected to the inner wall of the cabinet 1. The outer surface of the three-way pipe 1010 is fixedly connected to the inner wall of the circular hole 9. There are multiple rectangular plates 1009, and the multiple rectangular plates 1009 are distributed on the outer surface of the short round rod 1008. When in use, the air flow flows from the air-permeable plate 801 to the outside of the cabinet 1. According to the direction of the air flow, the drive shaft of the servo motor 804 rotates to drive the rotating guide plate 805 to rotate, and the air flow is discharged from the cabinet 1 through the air-permeable plate 801. The dust-proof cover 806 prevents the solid particles scraped off by the scraping rod 616 from entering the cabinet 1. The filter net 807 isolates external fine dust and other impurities. The water pump 1004 pumps the water in the water tank 1001 into the water-permeable plate 1006 through the second water pipe 1005. The water flow takes away the heat generated by the power components installed on the surface of the water-permeable plate 1006 through the tubular through-hole 1007. When the water flow passes through the rectangular plate 1009, it is blocked and the flow rate slows down, making the heat exchange effect more thorough and improving the heat dissipation effect. The cooling pipe 1002 is filled with liquid nitrogen. After the water flow flows out of the water-permeable plate 1006 and returns to the water tank 1001, it is cooled by the cooling pipe 1002 inside the water tank 1001, so that the water temperature is cooled and the water-cooling continues. After long-term use, the internal water flow needs to be replaced. Open the water outlet cover 1012 to let the water flow out. After the internal water flow is exhausted, close the water outlet cover 1012 and open the water inlet cover 1011 to pour water in.

[0030] When the present invention is in operation, the electrical components inside the cabinet body 1 are installed on the surface of the water-cooled heat dissipation device 10. When the internal electrical components start to generate heat, the heat dissipation device 6 absorbs gas from the outside and blows it into the cabinet body 1 to dissipate heat from the surface of the electrical components. The gas flows out from the ventilation device 8. The heat dissipation device 6 adjusts the wind direction according to the different heating degrees of the heating positions of the electrical components to precisely dissipate heat from each part. The ventilation device 8 then adjusts the air guiding position to circulate the air flow to the outside of the cabinet body 1. The water-cooled heat dissipation device 10 takes away the heat generated by the electrical components installed on its surface through the water flow. When the heat generated by the internal electrical components of the cabinet body 1 during operation is too large, the motor 612 starts to operate to drive the round rod 613 to rotate, and then drives the sleeve block 614 and the fan blade 615 fixed on the sleeve block 614 to rotate. The rotation of the fan blade 615 generates an air flow, sucking the outside air into the cabinet body 1 to take away the heat generated on the surface of the electrical components. When the filter plate 617 sucks in the air rotated by the fan blade 615, the dust and other particles carried in the air are isolated outside. At the same time, the scraping rod 616 rotates together with the round rod 613 to clean the filter plate 617 to prevent too many solid particles such as dust from adhering to the surface of the filter plate 617 during heat dissipation, which may hinder heat dissipation. According to the different heating degrees of the heating positions of the electrical components, the motor 603 operates to drive the driving gear 605 to rotate. The teeth of the driving gear 605 mesh with the teeth of the driven gear 608, thereby driving the driven gear 608 to rotate. The rotating plate one 606 and the rotating plate two 609 fixedly connected thereto rotate accordingly to adjust the wind direction and blow the air flow to the position with a stronger heating degree. The air flow blows over the electrical components to take away the generated heat and flows out of the cabinet body 1 through the air-permeable plate 801. According to the guiding direction of the air flow, the drive shaft of the servo motor 804 rotates to drive the rotating guide plate 805 to rotate, discharging the air flow out of the cabinet body 1 through the air-permeable plate 801. The dust-proof cover 806 prevents the solid particles scraped off by the scraping rod 616 from entering the cabinet body 1, and the filter net 807 isolates the external fine dust and other impurities. The water pump 1004 pumps the water in the water tank 1001 through the water pipe two 1005 into the water-permeable plate 1006. The water flow takes away the heat generated by the electrical components installed on the surface of the water-permeable plate 1006 through the tubular through holes 1007. When the water flow passes through the rectangular plate 1009, it is blocked and the flow rate slows down, making the heat exchange effect more thorough and improving the heat dissipation effect. The cooling pipe 1002 is filled with liquid nitrogen. After the water flow flows out of the water-permeable plate 1006 and returns to the water tank 1001, it is cooled by the cooling pipe 1002 inside the water tank 1001 to cool the water temperature and continue the water-cooled heat dissipation. After long-term use, the internal water flow needs to be replaced. Open the water outlet cover 1012 to let the water flow out. After the internal water flow is exhausted, close the water outlet cover 1012 and open the water inlet cover 1011 to pour water in.
