Description

Technical Field

[0001] The invention belongs to the technical field of high and low voltage power distribution equipment, and in particular relates to a self-controlled heat dissipation high and low voltage complete power distribution equipment. Background Art

[0002] High and low voltage distribution equipment is equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switchgear. When in use, the internal power distribution equipment often causes power loss to be converted into heat energy due to resistance and other reasons, causing the internal temperature of the distribution equipment to rise. If the internal temperature of the distribution equipment cannot be effectively cooled in time, it will affect the service life of the equipment, and in severe cases, it may cause fire and other problems.

[0003] At present, high and low voltage power distribution equipment generally adopts cooling fans or uses refrigerants for cooling and heat dissipation. When using cooling fans for cooling and heat dissipation, since the heat dissipation principle of the cooling fan is to accelerate the air circulation speed between the high and low voltage power distribution equipment and the outside world to cool and dissipate heat, when the outside temperature is high, the cooling fan will fail, the heat dissipation effect is poor, and it cannot be used in a high temperature environment; when using refrigerant radial cooling and heat dissipation, the refrigerant is used as a consumable to produce cold air to cool the inside of the high and low voltage power distribution equipment. Although this method has a better cooling effect than the cooling fan, since the refrigerant is a consumable, it needs to be manually replenished repeatedly after the refrigerant is used up, which is inconvenient to use and has a high cooling cost.

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0036] Example 1

[0037] This embodiment provides a self-controlled heat dissipation high and low voltage complete power distribution equipment, which has a unique structure, such as Figure 1-9 As shown, the self-controlled heat dissipation high and low voltage complete distribution equipment provided in this embodiment not only includes a base 1 and a distribution box body 2 fixed on the base 1, but also includes a cooling unit, a floor cooling circulation unit 3 and a temperature control unit. The distribution box body 2 is fixed to the ground through the base 1, and an exhaust fan is arranged in the distribution box body 2, and the exhaust fan is connected to the temperature control unit. A vent 21 is arranged on the back of the distribution box body 2. When the internal temperature of the equipment does not exceed the preset value during low-frequency use, the temperature control unit will control the exhaust fan to turn on for conventional ventilation and cooling. This method is an existing heat dissipation method, and the detailed working principle will not be described in detail.

[0038] The floor cooling circulation unit 3 includes a water pump, an inner barrel 31, an outer ring barrel 32, a water distributor 33 and a partition 34. The water pump is matched and installed in the inner barrel 31 and is connected to the temperature control unit. The inner barrel stores cooling liquid. The temperature control unit will control the opening and closing of the water pump according to the internal temperature of the distribution box body; the discharge end of the water pump is connected to the water inlet end of the water distributor 33. After the water pump is turned on, the water pump will extract the cooling liquid in the inner barrel and discharge it into the water distributor for drainage; the outer ring barrel is matched and installed in the upper part of the inner barrel, and is buried in the underground soil under the base together with the inner barrel.

[0039] Furthermore, the outer ring barrel and the inner barrel are both made of metal materials with good thermal conductivity.

[0040] like Figure 4 As shown, a plurality of cooling water tanks 35 are evenly divided along the circumference in the annular cavity inside the outer ring barrel 32 by a partition 34, the tops of the cooling water tanks are connected to each other, and the partition between the cooling water tank 35 at the head end and the cooling water tank 35 at the end extends upward to separate the two cooling water tanks; the cooling water tank 35 at the end is connected to the inner barrel, specifically:

[0041] like Figure 4 and Figure 5 As shown, a notch 36 connected to the inside of the inner barrel is radially opened on the inner ring wall of the outer ring barrel 32 at the cooling water tank 35 at the end, and the notch 36 is arranged at a position lower than the top of the cooling water tank, so that when the cold water with temperature is continuously discharged into the cooling water tank at the head end, when the cooling water fills the cooling water tank at the head end, the overflowing cooling water will automatically flow into the next cooling tank, and so on. Finally, when the cooling water flows into the cooling water tank at the end, the cooling water will flow into the inner barrel through the notch 36. In this process, the earth soil will continue to cool the cooling water.

[0042] The cooling unit includes a lifting plate 4, a cooling pipe 6, and a return water control box 7. A plurality of cooling pipes 6 are matched and installed on the inner wall of the distribution box body. The cooling pipes 6 are arranged vertically. The lifting plate 4 is matched and installed in the distribution box body 2, and cooling pipe avoidance grooves 41 are vertically arranged at the positions corresponding to the cooling pipes 6 around the lifting plate 4, so that the lifting plate can seal and divide the internal space of the distribution box body into upper and lower parts from top to bottom; the return water control box 7 includes a water collection box 71, a drainage box 72 and a pressure connection component 73. The water collection box 71 and the drainage box 72 are arranged on the lifting plate 4 from top to bottom, and are connected to each other through the pressure connection component 73. When the internal weight of the water collection box 71 reaches a preset value, the pressure connection component automatically opens to connect the water collection box with the drainage box. Specifically:

[0043] like Figure 6 As shown, the drainage box 72 is fixedly mounted on the lifting plate, and the pressure communication assembly 73 includes a square column 74 and a top support spring 75. The square column 74 is vertically fixed to the middle of the bottom surface of the water collection box 71, and a water passage 741 is vertically arranged inside the square column 74. The top of the water passage 741 is connected to the inside of the water collection box 71; a downwardly recessed square column mounting groove 76 is vertically arranged in the middle of the drainage box 72, and a water hole 761 connected to the inside of the drainage box 72 is horizontally opened on the groove wall on one side of the square column mounting groove 76; the square column 74 is matched and inserted into the bottom of the square column mounting groove, and a drainage hole 742 connected to the water passage 741 is opened on the side wall of the bottom end of the square column in the mounting groove of the square column 74, and the drainage hole 742 is overlapped and connected with the water hole 761;

[0044] The top support spring 75 is matched and sleeved on the square column 74 between the water collection box 71 and the drainage box 72, and in a natural state, the top support spring 75 will push the water collection box upward to drive the square column to slide upward along the square column mounting groove without falling out of the square column mounting groove, so that the drainage hole is blocked by the groove wall inside the square column mounting groove; therefore, when water is continuously injected into the water collection box, as the weight of the water collection box increases, the top support spring will be squeezed and produce elastic contraction, so that the water collection box can press the square column to move down along the square column mounting groove so that the drainage hole overlaps and is connected with the water through hole.

[0045] The drainage box 72 is connected to the cooling water tank located at the head end in the outer ring barrel, one end of the cooling pipe is connected to the drainage end of the water distributor, and the other end is connected to the water collection box. Specifically: a return pipe 77 is vertically arranged on the outside of the distribution box body, one end of the return pipe 77 extends upward into the distribution box body, and is connected to the drainage box 72 through a hose 78, and the other end of the return pipe 77 extends downward into the base and is connected to the cooling water tank located at the head end in the outer ring barrel; the water distributor is matched and installed in the base, and the top end of the cooling pipe is connected to the water collection box through a hose 78, and the other end of the cooling pipe extends downward into the base, and is connected to the drainage end on the water distributor in the base through a hose.

[0046] The temperature control unit includes a controller and a temperature sensor. The temperature sensor is installed in the distribution box body and connected to the controller. It is used to detect the real-time temperature in the distribution box body and send real-time temperature data to the controller. The controller is connected to the water pump and exhaust fan control, and the controller will control the start and stop of the water pump and exhaust fan according to the distribution box body.

[0047] When the self-controlled heat dissipation high and low voltage complete distribution equipment provided in this embodiment is in use, when the internal temperature of the distribution box body does not exceed the preset value, the temperature control unit will control the exhaust fan to turn on, discharge the hot air inside the distribution box body, and perform conventional ventilation and cooling; when the internal temperature of the distribution box body exceeds the preset value, that is, the exhaust fan cannot effectively cool the inside of the distribution box body, the temperature control unit will control the water pump to turn on to extract the cooling liquid in the inner barrel, and discharge it into the various cooling pipes in the distribution box body 2 through the water distributor, and converge in the junction box. In this process, when the cooling liquid flows through the cooling pipe and enters the junction box, it will absorb the heat inside the distribution box body, thereby quickly cooling the inside of the distribution box body. When the cooling liquid converged in the junction box absorbs heat, its own temperature will rise. When the weight of the cooling liquid converged in the junction box reaches the preset value, the pressure connecting component 73 will automatically open, so that the temperature The elevated cooling liquid is continuously discharged into the cooling water tank located at the head end of the underground outer ring barrel 32 through the drainage box via the return pipe 77, and is cooled by heat exchange with the underground soil; as the water pump continues to work, the cooling liquid continuously discharged back through the return pipe passes through each cooling water tank in turn along the circumference to exchange heat with the underground soil, and then is discharged into the inner barrel for recycling. Compared with the existing high and low voltage complete distribution equipment, the high and low voltage complete distribution equipment provided in this embodiment can automatically control the heat dissipation in the distribution box body through the temperature control unit. When the traditional air cooling cannot meet the heat dissipation demand inside the distribution box body, the cooling mode will be automatically switched, and the inside of the distribution box body will be cooled by the flow of cooling liquid, thereby improving the cooling effect. Moreover, the cooling liquid whose temperature rises after use can be continuously used after being cooled by heat exchange with the underground soil, without the need to repeatedly replenish or replace the cooling liquid, with low maintenance cost and environmental protection.

[0048] Example 2

[0049] The difference between Example 2 and Example 1 is that Figure 4 As shown, a heat-conducting copper plate is provided along the circumference on the outer ring surface of the outer ring barrel and the outer ring surface of the inner barrel below the outer ring barrel. The heat-conducting copper plate is buried in the underground soil together with the outer ring barrel and the inner barrel. The contact area between the inner barrel, the outer ring barrel and the soil can be increased through the use of the heat-conducting copper plate, thereby improving the heat exchange efficiency between the inner barrel, the outer ring barrel and the soil, and accelerating the cooling efficiency and effect of the coolant.

[0050] Example 3

[0051] The difference between Example 3 and Example 2 is that a heat insulation layer is provided between the outer ring barrel and the inner barrel. The purpose of providing the heat insulation layer is to reduce the influence of the heat of the coolant in the outer barrel on the coolant in the inner barrel, and to prevent the coolant in the inner barrel from being affected by the heat of the used coolant in the outer ring barrel and causing the temperature to rise, thereby affecting the cooling effect of the refrigerant in the inner barrel.

[0052] Example 4

[0053] The difference between Example 4 and Example 3 is that the cooling unit further includes an elastic supporting mechanism.

[0054] like Figure 10-12 As shown, the lifting plate 4 is matched and installed in the distribution box body through an elastic support mechanism 5. The elastic support mechanism 5 includes a support platform 51 arranged below the four top corners of the lifting plate in the distribution box body. The support platform 51 is fixedly connected to the inner wall of the distribution box body. A sliding hole 511 is vertically opened in the middle of the support platform 51. A sliding rod 52 is matched and installed in the sliding hole 511. The bottom end of the sliding rod 52 extends downward from the support plate and is fixed with an anti-slip block 53. The top of the sliding rod 52 is vertically connected to the bottom surface of the lifting plate 4, and the sliding rod 52 between the support platform 51 and the lifting plate are matched and installed with a support spring 54. In a natural state, the support spring will push the lifting plate upward to drive the anti-slip block and lift it, and touch the bottom surface of the support platform. When the weight inside the water collection box reaches the pressure, the connecting component is automatically opened, and the lifting platform will synchronously descend to squeeze the support spring to cause it to produce elastic compression.

[0055] Furthermore, a blocking fence 55 is vertically slidably installed on the inner wall of the distribution box body 2 at the inner opening of the vent, and the blocking fence 55 includes a rectangular frame 551 slidably set with the inner wall of the distribution box body 2, and the vent 21 is located in the rectangular frame, and the rectangular frame is connected to the upper lifting plate by a pull rope or a connecting rod. When the lifting plate descends, it will drive the rectangular frame to descend synchronously, and a seal 552 is matched above each vent 21 in the rectangular frame. The seal is set in contact with the inner wall of the distribution box body 2, and the left and right ends of the seal are fixedly connected to the rectangular frame. Compared with Example 1, when the self-controlled heat dissipation high and low voltage complete distribution equipment provided by this embodiment is in use, when the internal temperature of the distribution box body exceeds the preset value and the water pump is started for water cooling, when the pressure connection component is opened, the lifting plate will be driven to descend synchronously by the weighted water tank, thereby driving the rectangular frame to drive each seal to descend synchronously to block the vent 21, so that when the inside of the distribution box body is cooled, the external high-temperature gas enters the distribution box body and affects the cooling effect.

[0056] Example 5

[0057] The difference between Example 5 and Example 4 is that the cooling pipe structure is different.

[0058] like Fig.13 and Fig.14 As shown, the cooling pipeline includes a metal shell tube 61 arranged vertically, both upper ends of the shell tube 61 are blocked ends, and the lifting plate can move up and down along the metal shell tube and the distribution box body; a metal water pipe 62 is matched and installed in the shell tube, and the top of the water pipe 62 extends upward from the shell tube 61 and is connected with the water collection box 71 through the hose 22; the bottom end of the water pipe extends downward into the base and is connected with the drainage end of the water distributor; a plurality of exhaust ports 63 connected with the inside of the shell tube are vertically built on the side wall of the shell tube, and the exhaust ports are all located below the lifting plate in the raised state. When the lifting plate is lowered, the internal spaces of the distribution box bodies on the upper and lower layers of the lifting plate are connected through the exhaust ports on the shell tube.

[0059] An exhaust fan is installed in the main body of the distribution box above the lifting plate, and the exhaust fan is connected to the control unit. A plurality of vents are vertically opened on the upper edge of the lifting plate, and the exhaust end of the exhaust fan is connected to the vent through a spring tube. Compared with Example 4, when the self-controlled heat dissipation high and low voltage complete distribution equipment provided in this embodiment is in use, after the lifting plate is lowered, the control unit will control the exhaust fan to turn on, thereby extracting the air in the main body of the distribution box below the lifting plate and discharging it into the main body of the distribution box above the lifting plate, and the air discharged into the main body of the distribution box above the lifting plate will enter the outer shell tube through the exhaust port of the outer shell tube above the lifting plate in the descending state, and after being cooled through the water pipe in the outer shell tube, it will be discharged from the exhaust port below the lifting plate in the descending state, thereby accelerating the internal circulation of the air inside the distribution box body and further improving the cooling effect.

[0060] Example 6

[0061] The difference between Example 6 and Example 5 is that an evaporative cooling device is provided on the outside of the distribution box body.

[0062] like Fig.15 As shown, the evaporative cooling device includes an evaporation box body 81 fixed on the outer side wall of the distribution box body 2, an installation port connected to the interior is opened on the outer wall of one side of the evaporation box body 81, and an evaporation fan 82 is installed, and the evaporation fan is connected to the control unit. A heat sink 83 is provided on the outer side wall of the distribution box body in the evaporation box body, and the heat sink 83 passes through the side wall of the distribution box body 2 and extends into the distribution box body 2; a water collecting tank 84 is provided above the evaporation box body 81, and a drip hole 85 connected to the evaporation box body is opened at the bottom of the water tank, and the drip hole is located on the heat sink 83. Above, a V-shaped water collecting trough is provided on the top of the distribution box body, and a drain outlet is provided at the bottom of the trough wall on one side of the water collecting trough, and is connected to the water supply tank through a drain pipe; when in use, rainwater falling on the top of the distribution box body will be discharged into the water collecting tank through the drain pipe, and drip onto the heat sink through the drip holes. When the temperature inside the distribution box body 2 is high, the control unit will control the evaporation fan to turn on, speeding up the evaporation rate of water droplets on the heat sink, and while the water droplets absorb heat and evaporate, the heat sink will be cooled, thereby assisting in cooling the inside of the distribution box body.

[0063] Example 7

[0064] The difference between Example 7 and Example 6 is that an adsorption cooling component is provided in the main body of the distribution box.

[0065] like Fig.16 As shown, the adsorption file includes a ventilation hose 91, one end of the ventilation hose 91 is connected to any exhaust port on the outer shell tube below the lifting plate in the descending state, and the other end of the ventilation hose is equipped with an air outlet nozzle 92. The ventilation hose on the rear side of the air outlet nozzle is matched with a magnet block. When the self-controlled heat dissipation high and low voltage complete distribution equipment provided by this embodiment is in use, the air outlet nozzle can be adsorbed and fixed to the power-enhanced electrical component accessories in the main body of the distribution box by a magnet, so that the air cooled by the water pipe can be directly blown onto the corresponding electrical components to cool down the key parts.
