Description

Technical Field

[0001] This invention belongs to the field of power grid related technology, and more specifically, it relates to a high-temperature resistant power metering box with a heat dissipation structure. Background Technology

[0002] With the rapid development of the power grid, especially in today's era of advanced power grids, there is a growing need to calculate the electricity consumption of the power grid. As a result, a large number of meter boxes are needed to house and fix the meters. These meters are generally high-voltage and high-power meters, which generate a lot of heat during use.

[0003] The existing technology still has the following technical problems: While existing electricity metering boxes can dissipate heat and cool down through intake and exhaust fans, they lack an effective heat dissipation structure. This prevents them from quickly cooling down high-temperature electronic components, resulting in poor high-temperature resistance. Furthermore, the absence of an effective liquid cooling structure means that when hot electronic components cannot be cooled down by air, a fire is more likely to occur, further contributing to poor high-temperature resistance.

[0010] In a further technical solution, a U-shaped bracket is fixedly connected to the bottom of the guide plate, a first electric push rod is fixedly installed on the outer wall of the U-shaped bracket, the output end of the first electric push rod is fixedly connected to the movable frame, sliding blocks are fixedly connected to the outer walls on both sides of the movable frame, a guide rod is fixedly connected between the guide plate and the U-shaped bracket, and the guide rod is slidably connected to the sliding block.

[0012] In a further technical solution, a storage box is fixedly connected to the bottom of the L-shaped air duct, a pump body is fixedly installed on the outer wall of the storage box, a hose is fixedly connected to the outer side of the pump body, the hose is fixedly connected to the nozzle, and a solenoid valve is fixedly installed on the hose.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, when the temperature sensor inside the energy metering box detects a high temperature in an electronic component, the guide plate rotates, and the deflection direction of the guide plate corresponds to the high-temperature electronic component. The guide plate directs cool air towards the high-temperature electronic component, providing initial heat dissipation and cooling. During this process, the cool air, after passing through the guide plate, diffuses and circulates within the energy metering box, also contributing to the cooling of other electronic components inside the box. Subsequently, the opening on one side of the L-shaped air duct is moved above the guide plate, and then the L-shaped air duct is moved to the outside of the high-temperature electronic component. At this point, the cool air... When the air passes through the guide plate, a portion of the cool air is delivered to the cantilever through the L-shaped air duct. The cool air is then sprayed onto the high-temperature electronic components through the cantilever, providing secondary cooling for these components. The combination of the guide plate and the L-shaped air duct in this invention enhances the heat dissipation intensity for high-temperature electronic components, providing high-temperature resistance. Furthermore, during the process of the guide plate drawing in cool air, the cool air circulates within the energy metering box, allowing other electronic components inside the box to dissipate heat simultaneously. This prevents all the cool air from being delivered to the high-temperature electronic components, which would otherwise prevent the remaining electronic components inside the energy metering box from being completely unable to dissipate heat.

[0017] 2. When the temperature of high-temperature electronic components cannot be lowered by air cooling, the output end of the third electric push rod can drive the cantilever and air outlet to retract and reset. The output end of the fourth electric push rod can drive the nozzle to be pushed out of the air outlet. Then, the output end of the second motor drives the power shaft to rotate. The power shaft can drive the rotating frame to rotate through the transmission of spur gear and internal gear, which in turn can drive the nozzle set on the outside of the rotating frame to rotate, so that the nozzle can rotate outside the high-temperature electronic components. When the nozzle rotates to the corresponding heating part, the pump body is started and the solenoid valve is opened. The pump body draws the coolant inside the storage tank into the nozzle through the hose. This coolant is a highly insulating, non-conductive electronic-grade fluorinated liquid. Under the pressure of the pump body, the coolant is accurately sprayed to the corresponding heating part through the nozzle to cool it down. This invention can drive the nozzle to move to the corresponding heating part, so that the coolant can be accurately sprayed to the corresponding heating part through the nozzle, improving the high temperature resistance and preventing fire.

[0018] 3. When the intake fan located on one side of the electricity metering box is activated, cool air from the outside can enter the intake duct through the first dustproof net. The cool air is then transported to the intake channel through the intake duct and, under the action of the guide plate, can be directed towards the electronic components inside the electricity metering box, thereby improving the heat dissipation effect of the electronic components inside the electricity metering box. In addition, the exhaust fan located on the other side of the electricity metering box can draw the hot air inside the electricity metering box into the exhaust duct through the exhaust channel, and finally discharge it through the second dustproof net on one side of the exhaust duct. In this invention, the intake fan located on one side of the electricity metering box can transport cool air from the outside into the electricity metering box, the guide plate can direct the cool air towards the electronic components inside the electricity metering box, and the exhaust fan located on the other side of the electricity metering box can draw out the hot air inside the electricity metering box, thereby improving the heat dissipation effect of the electricity metering box.

[0029] In this embodiment, the first motor 7, which is fixedly mounted on the outside of the first mounting plate 6, is activated. The output end of the first motor 7 can drive the rotating shaft 10 and the guide plate 13 to rotate under the meshing transmission of the worm gear 8 and the worm wheel 9. This causes the deflection direction of the guide plate 13 to correspond to the electronic device with a higher temperature. The guide plate 13 will guide the cold air towards the electronic device with a higher temperature, which can perform preliminary heat dissipation and cooling on the electronic device with a higher temperature. During the process of guiding the air, the cold air will diffuse and circulate in the power metering box 1 after passing through the guide plate 13, which also has a certain heat dissipation effect on the other electronic devices inside the power metering box 1.

A fixed plate 23 is fixedly connected to the output end of the second electric push rod 22.

[0035] In this embodiment, after the electric slider 20 is started, it will slide on the guide rail 21, thereby driving the L-shaped air duct 19 to slide within the movable frame 16. When the L-shaped air duct 19 moves to the corresponding position, the output end of the second electric push rod 22 can drive the fixing plate 23 to press against the inner wall of the movable frame 16, thereby limiting and fixing the adjusted L-shaped air duct 19.

[0036] Preferably, a storage box 28 is fixedly connected to the bottom of the L-shaped air duct 19, a pump body 29 is fixedly installed on the outer wall of the storage box 28, a hose 30 is fixedly connected to the outer side of the pump body 29, the hose 30 is fixedly connected to the nozzle 39, and a solenoid valve 41 is fixedly installed on the hose 30.

[0037] In this embodiment, the pump body 29 draws the coolant inside the storage tank 28 through the hose 30 into the nozzle 39. The coolant is a highly insulating, non-conductive electronic-grade fluorinated liquid, which allows the coolant to be precisely sprayed through the nozzle 39 to the corresponding heated parts under the pressure of the pump body 29 and to cool them down.

[0038] Preferably, a second motor 31 is fixedly installed on the outer wall of the cantilever 26. The output end of the second motor 31 is fixedly connected to a power shaft 32.

The internal gear 34 is fixedly connected to the rotating frame 35.

[0039] In this embodiment, the output end of the second motor 31 drives the power shaft 32 to rotate.

[0042] Preferably, an exhaust duct 42 is fixedly installed above the side of the power metering box 1 away from the air inlet duct 5. An exhaust pipe 43 is fixedly connected to the outer wall of the exhaust duct 42. An exhaust fan 44 is fixedly installed inside the exhaust pipe 43. A second dustproof net 45 is provided on one side of the exhaust pipe 43.

[0043] In this embodiment, the exhaust fan 44 installed on the other side of the electricity metering box 1 can draw the hot air inside the electricity metering box 1 into the exhaust pipe 43 through the exhaust channel 42, and finally discharge it through the second dustproof net 45 on one side of the exhaust pipe 43. The second dustproof net 45 has a dustproof function, reducing the corrosion of external dust on the electronic components inside the electricity metering box 1.

[0044] Working principle of the invention: Step 1: When using this invention, the intake fan 4 located on the lower side of the energy metering box 1 is activated, allowing cool air from the outside to enter the intake duct 2 through the first dustproof net 3. The first dustproof net 3 has a dustproof function, reducing the corrosion of external dust on the electronic components inside the energy metering box 1. Then, the cool air is delivered to the intake channel 5 through the intake duct 2, and under the action of the guide plate 13, the cool air is guided towards the electronic components inside the energy metering box 1, which can improve the heat dissipation effect of the electronic components inside the energy metering box 1. In addition, the exhaust fan 44 located on the upper side of the other side of the energy metering box 1 can draw the hot air inside the energy metering box 1 into the exhaust duct 43 through the exhaust channel 42, and finally discharge it through the second dustproof net 45 on the side of the exhaust duct 43. The second dustproof net 45 has a dustproof function, reducing the corrosion of external dust on the electronic components inside the energy metering box 1. The present invention uses an intake fan 4 located on the lower side of one side of the power metering box 1 to deliver cool air from the outside into the power metering box 1. A guide plate 13 can direct the cool air toward the electronic components inside the power metering box 1. An exhaust fan 44 located on the upper side of the other side of the power metering box 1 can extract the hot air from inside the power metering box 1, thereby improving the heat dissipation effect of the power metering box 1.

[0045] Step 2: When the temperature sensor inside the power metering box 1 detects that a certain electronic device has a high temperature, the first motor 7, which is fixedly installed on the outside of the first mounting plate 6, is activated. The output end of the first motor 7 can drive the rotating shaft 10 and the guide plate 13 to rotate under the meshing transmission of the worm gear 8 and the worm wheel 9. This makes the deflection direction of the guide plate 13 correspond to the electronic device with a high temperature. The guide plate 13 will guide the cold air towards the electronic device with a high temperature, which can perform preliminary heat dissipation and cooling of the electronic device with a high temperature. During the process of guiding the air, the cold air will diffuse and circulate inside the power metering box 1 after passing through the guide plate 13, which also has a certain heat dissipation effect on the other electronic devices inside the power metering box 1. Then, the first electric push rod 15, which is fixedly installed on the outside of the U-shaped bracket 14, is activated. The output end of the first electric push rod 15 will drive the moving frame 16 and the L-shaped air duct 19 to move, so that the opening on one side of the L-shaped air duct 19 moves above the guide plate 13. Then, the electric slider 20 slides on the guide rail 21 and drives the L-shaped air duct 19 to move inside the moving frame 16. Because the deflection direction of the guide plate 13 corresponds to the high-temperature electronic device, the L-shaped air duct 19 can move to the outside of the high-temperature electronic device. At this time, when the cold air passes through the guide plate 13, part of the cold air will be delivered to the cantilever 26 through the L-shaped air duct 19. The output end of the third electric push rod 25 can drive the cantilever 26 to move, so that the air outlet 27 is close to the high-temperature electronic device. Then, the cold air passes through the cantilever 26 and is sprayed onto the high-temperature electronic device, which can perform secondary heat dissipation and cooling on the high-temperature electronic device. The air guide plate 13 and the L-shaped air duct 19 of this invention can improve the heat dissipation intensity of high-temperature electronic devices and have high temperature resistance. In addition, during the process of air guide plate 13 guiding cold air, the cold air will circulate in the power metering box 1, so that the other electronic devices inside the power metering box 1 can also dissipate heat at the same time, avoiding the cold air being delivered to the high-temperature electronic devices, which would cause the other electronic devices inside the power metering box 1 to be unable to dissipate heat at all.

[0046] Step 3: When the temperature of a high-temperature electronic device cannot be lowered by air cooling, the output end of the third electric push rod 25 can drive the cantilever 26 and the air outlet 27 to retract and reset. The output end of the fourth electric push rod 37 can drive the nozzle 39 to be pushed out of the air outlet 27 through the connecting shaft 40 and the support plate 38. Then, the output end of the second motor 31 drives the power shaft 32 to rotate. The power shaft 32 can drive the rotating frame 35 to rotate through the transmission of the spur gear 33 and the internal gear 34. This can drive the nozzle 39 set on the outside of the rotating frame 35 to rotate, so that the nozzle 39 can rotate outside the high-temperature electronic device. When the nozzle 39 rotates to the corresponding heating part, the pump body 29 is started and the solenoid valve 41 is opened. The pump body 29 draws the coolant inside the storage tank 28 into the nozzle 39 through the hose 30. This coolant is a highly insulating, non-conductive electronic-grade fluorinated liquid. Under the pressure of the pump body 29, the coolant is accurately sprayed to the corresponding heating part through the nozzle 39 to cool it down. This invention can move the nozzle 39 to the corresponding heating part, so that the coolant can be accurately sprayed to the corresponding heating part through the nozzle 39, which can improve the high temperature resistance and prevent fire.
