Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a comprehensive high and low voltage complete power distribution cabinet with environmental protection and low energy consumption functions. Background Art

[0002] The distribution cabinet (box) is a general term for the motor control center, which is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box), etc. It is the final equipment of the distribution system. The complete set of distribution cabinets is also called a complete set of switch cabinets. It is a kind of power equipment that adjusts the voltage or current through the internal circuit system and outputs it stably. It is often used in the conversion of high and low voltage lines.

[0003] When cooling the distribution box, the existing device cannot dissipate heat for power supply components in different areas at the same time, nor can it dissipate heat for specific heating points. It cannot cool the heating power supply components individually, has poor targeting, and has low heat dissipation efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides: a comprehensive high and low voltage complete set of power distribution cabinets with environmental protection and low energy consumption functions, specifically comprising:

[0005] A cabinet body having a rectangular structure and a cabinet door arranged outside the cabinet body, a waterproof baffle plate being installed on the top of the cabinet body, and a heat dissipation device being installed inside the cabinet body;

[0006] A mounting plate, the mounting plate having a long strip structure, and a power supply assembly arranged on one side of the mounting plate, the power supply assembly being fixedly connected to the mounting plate through a fixing member, and the mounting plate being arranged inside the cabinet;

[0007] The heat dissipation device comprises:

[0008] A heat dissipation bellows, the heat dissipation bellows having a bellows cylinder and a fan arranged inside the heat dissipation bellows, the outer side of the heat dissipation bellows being fixedly connected to the cabinet through a fixing sleeve, a filter screen being installed on the inner wall of the heat dissipation bellows, an air inlet being opened at one end of the heat dissipation bellows away from the filter screen, and a trigger device being installed at one end of the heat dissipation bellows away from the air inlet;

[0009] The heat dissipation pipe has an L-shaped structure and an adjusting device arranged at one end of the heat dissipation pipe, and the end of the heat dissipation pipe away from the adjusting device is connected to the heat dissipation bellows.

[0010] Turn on the fan to draw external air from the air inlet into the heat dissipation bellows, and then discharge it into the cabinet from the heat dissipation pipe after being filtered by the filter. Since there are multiple groups of heat dissipation pipes, the incoming air can be blown directly from the heat dissipation pipes to the power supply components at the other end of the heat dissipation pipes. Multiple heat dissipation pipes can dissipate heat for power supply components in different areas at the same time, thereby improving the heat dissipation efficiency of the device.

[0011] The heat dissipation device comprises an adjusting cylinder, wherein a heat conducting fin is installed at a position near the top of the inner wall of the adjusting cylinder, and an exhaust port is opened on the inner wall of the heat pipe near one end of the adjusting cylinder, and the inner wall of the adjusting cylinder is slidably connected with a piston with a rod, and the top of the piston with a rod extends to the interior of the heat pipe and is fixedly connected with a sealing plate, and a sealing ring is arranged on the top of the adjusting cylinder. When the temperature of a power supply component in the cabinet rises, the heat conducting fin connected to the power supply component transfers the temperature to the corresponding adjusting cylinder, and the expansion medium in the adjusting cylinder expands due to heat and pushes the piston with a rod to slide downward. As the temperature of the piston with a rod rises, the farther it is from the position of the heat conducting fin, the sealing plate is pulled during the sliding of the piston with a rod, and the sealing plate is pulled out of the heat dissipation pipe. The sealing plate originally located above the exhaust port gradually slides to below the exhaust port, so that the gas in the heat dissipation pipe can be blown from the exhaust port to the surface of the power supply component, so that the heat can be dissipated at the specific heating point, and the heating power supply component can be cooled separately, thereby improving the targeting and increasing the efficiency of the separate heat dissipation.

[0012] The heat-conducting fins are arranged in multiple groups and are evenly mounted on the regulating cylinder. The top of the regulating cylinder is fixedly connected to an end of the heat dissipation pipe away from the heat dissipation bellows.

[0013] The heat conducting fin extends to the power supply assembly at one end away from the regulating cylinder, the exhaust port is provided with multiple groups, the top of the piston with rod passes through the sealing ring, and the inside of the regulating cylinder above the piston with rod is filled with expansion medium.

[0014] The trigger device includes a piston cylinder, one end of the piston cylinder is connected to an extension cylinder, the end of the piston cylinder away from the extension cylinder is connected to a buffer cylinder, the inner wall of the piston cylinder is fixedly connected to a heat-conducting strip, the inner wall of the buffer cylinder is fixedly connected to a plug through an arc spring, the inner wall of the piston cylinder away from the buffer cylinder is slidably connected to a movable piston, the end of the movable piston away from the piston cylinder extends to the interior of the extension cylinder and is provided with a groove, the inner wall of the groove is fixedly connected to a pressing block through a compression spring, the end of the movable piston close to the groove is fixedly connected to an annular switch sheet, and a trigger is installed on the inner wall of the extension cylinder near the pressing block. The trigger switch is triggered, and a fixed switch piece is installed on the inner wall of the extension cylinder near the position of the trigger switch. The heat conductive strip transfers the temperature inside the cabinet to the inside of the piston cylinder. The expansion medium in the piston cylinder expands due to heat and pushes the moving piston to move. When the temperature in the cabinet is high, the expansion medium in the piston cylinder pushes the moving piston and drives the pressing block to squeeze the trigger switch. The trigger switch turns on the fan. When the temperature in the cabinet is low, the expansion medium in the piston cylinder contracts and drives the pressing block to move. The pressing block no longer squeezes the trigger switch and the fan is turned off. The fan switch can be controlled according to the temperature in the cabinet to avoid the fan running all the time and consuming a lot of energy, thereby achieving the effect of energy saving and consumption reduction.

[0015] One end of the piston cylinder close to the extension cylinder passes through the heat dissipation bellows and is fixedly connected to the heat dissipation bellows, one end of the heat conductive strip away from the piston cylinder extends to the inside of the cabinet, and the plug is located at the connection between the buffer cylinder and the piston cylinder.

[0016] The annular switch piece and the fixed switch piece are both arranged on the control circuit of the external alarm system, and the trigger switch is arranged on the control circuit of the fan. When the temperature in the cabinet continues to rise, the expansion medium in the piston cylinder continues to push the moving piston to move, and the moving piston squeezes the pressing block and gradually approaches the fixed switch piece. When the temperature in the cabinet continues to be high and cannot be reduced, the moving piston drives the annular switch piece to contact the fixed switch piece, and the external alarm system is triggered at this time. When the fan is damaged, an alarm is promptly issued to notify the staff to carry out emergency repairs to avoid safety accidents such as fire caused by excessive temperature. As the expansion medium in the piston cylinder continues to expand, the medium pushes the moving piston to one end of the extension cylinder, and the moving piston cannot continue to move. At this time, the expansion medium pushes the plug to squeeze the arc spring, pushing the plug into the buffer cylinder, and the expansion medium inside the piston cylinder can enter the buffer cylinder to prevent the piston cylinder from bursting due to excessive temperature, thereby playing a protective role.

[0017] Preferably, the mounting plate, power supply assembly and fixing member are provided in multiple groups, and both ends of the mounting plate are fixedly connected to the inner wall of the cabinet.

[0018] Preferably, the fixing sleeve is arranged on the heat dissipation bellows, the heat dissipation bellows is arranged inside the cabinet, one end of the heat dissipation bellows close to the air inlet extends to the outside of the cabinet, and the heat dissipation pipes are arranged in multiple groups.

[0019] The present invention provides a comprehensive high and low voltage complete set of power distribution cabinets with environmental protection and low energy consumption functions. It has the following beneficial effects:

[0020] 1. This is an integrated high and low voltage power distribution cabinet with environmental protection and low energy consumption functions. Through the installation of the heat dissipation device, the fan is turned on to draw the external air from the air inlet to the heat dissipation bellows, and the air is discharged into the cabinet from the heat dissipation pipe after being filtered by the filter. Since there are multiple groups of heat dissipation pipes, the incoming air can be blown directly from the heat dissipation pipe to the power supply component at the other end of the heat dissipation pipe. Multiple heat dissipation pipes can dissipate heat for power supply components in different areas at the same time, thereby improving the heat dissipation efficiency of the device.

[0021] 2. This is an integrated high and low voltage distribution cabinet with environmental protection and low energy consumption functions. Through the installation of adjustment devices and heat dissipation devices, when the temperature of a power supply component in the cabinet rises, the heat-conducting fins connected to the power supply component transfer the temperature to the corresponding adjustment cylinder. The expansion medium in the adjustment cylinder expands due to heat and pushes the piston with rod to slide downward. As the temperature rises, the piston with rod is farther away from the heat-conducting fin. During the sliding process of the piston with rod, the sealing plate is pulled and the sealing plate is pulled out of the heat pipe. The sealing plate originally located above the exhaust port gradually slides to the bottom of the exhaust port, so that the gas in the heat pipe can be blown from the exhaust port to the surface of the power supply component, so as to dissipate heat at specific heating points and concentrate on cooling the heating power supply components separately, thereby improving the targeting and increasing the efficiency of separate heat dissipation.

[0022] 3. This is an integrated high and low voltage distribution cabinet with environmental protection and low energy consumption functions. Through the installation of the trigger device, the heat-conducting strip transfers the temperature inside the cabinet to the inside of the piston cylinder. The expansion medium in the piston cylinder expands due to heat and pushes the moving piston to move. When the temperature in the cabinet is high, the expansion medium in the piston cylinder pushes the moving piston and drives the pressing block to squeeze the trigger switch. The trigger switch turns on the fan. When the temperature in the cabinet is low, the expansion medium in the piston cylinder contracts and drives the pressing block to move. The pressing block no longer squeezes the trigger switch and the fan is turned off. The fan switch can be controlled according to the temperature in the cabinet to avoid the fan running all the time and consuming a lot of energy, thereby achieving the effect of energy saving and consumption reduction.

[0023] 4. This is an integrated high and low voltage distribution cabinet with environmental protection and low energy consumption functions. Through the setting of the buffer cylinder, when the temperature in the cabinet continues to rise, the expansion medium in the piston cylinder continues to push the moving piston to move, and the moving piston squeezes the pressing block and gradually approaches the fixed switch piece. When the temperature in the cabinet continues to be high and cannot be reduced, the moving piston drives the annular switch piece to contact the fixed switch piece, and the external alarm system is triggered at this time. When the fan is damaged, an alarm is promptly issued to notify the staff to carry out emergency repairs to avoid safety accidents such as fire caused by excessive temperature. As the expansion medium in the piston cylinder continues to expand, the medium pushes the moving piston to one end of the extension cylinder, and the moving piston cannot continue to move. At this time, the expansion medium pushes the plug to squeeze the arc spring and pushes the plug into the buffer cylinder. The expansion medium inside the piston cylinder can enter the buffer cylinder to prevent the piston cylinder from bursting due to excessive temperature, thereby playing a protective role.

[0036] The heat dissipation device 4 comprises:

[0037] A heat dissipation bellows 41, which has a bellows cylinder and a fan 42 arranged inside the heat dissipation bellows 41, the outer side of the heat dissipation bellows 41 is fixedly connected to the cabinet 1 through a fixing sleeve 43, a filter 44 is installed on the inner wall of the heat dissipation bellows 41, an air inlet 45 is opened at one end of the heat dissipation bellows 41 away from the filter 44, and a trigger device 48 is installed at one end of the heat dissipation bellows 41 away from the air inlet 45;

[0038] The heat dissipation pipe 46 has an L-shaped structure and an adjustment device 47 is arranged at one end of the heat dissipation pipe 46 . One end of the heat dissipation pipe 46 away from the adjustment device 47 is connected to the heat dissipation bellows 41 .

[0039] The mounting plate 5 , the power supply assembly 6 and the fixing member 7 are all provided in multiple groups, and both ends of the mounting plate 5 are fixedly connected to the inner wall of the cabinet 1 .

[0040] The fixing sleeve 43 is sleeved on the heat dissipation bellows 41 . The heat dissipation bellows 41 is arranged inside the cabinet 1 . One end of the heat dissipation bellows 41 close to the air inlet 45 extends to the outside of the cabinet 1 . A plurality of heat dissipation pipes 46 are arranged.

[0041] The adjusting device 47 includes an adjusting cylinder 471, a heat-conducting fin 472 is installed on the inner wall of the adjusting cylinder 471 near the top, an exhaust port 473 is opened on the inner wall of the heat dissipation tube 46 near one end of the adjusting cylinder 471, a piston 474 with a rod is slidably connected to the inner wall of the adjusting cylinder 471, the top of the piston 474 with a rod extends to the interior of the heat dissipation tube 46 and is fixedly connected to a sealing plate 475, and a sealing ring 476 is arranged on the top of the adjusting cylinder 471.

[0042] There are multiple groups of heat-conducting fins 472 that are evenly mounted on the regulating tube 471 . The top of the regulating tube 471 is fixedly connected to one end of the heat dissipation pipe 46 away from the heat dissipation bellows 41 .

[0043] The heat conducting fin 472 extends to the power supply assembly 6 at one end away from the regulating cylinder 471, and multiple groups of exhaust ports 473 are provided. The top of the rod piston 474 passes through the sealing ring 476, and the interior of the regulating cylinder 471 located above the rod piston 474 is filled with expansion medium.

[0044] When in use, the fan 42 is turned on to draw external air from the air inlet 45 into the heat dissipation bellows 41, and the air is discharged from the heat dissipation pipe 46 into the cabinet 1 after being filtered by the filter 44. Since the heat dissipation pipe 46 is provided with multiple groups, the incoming air can be blown directly from the heat dissipation pipe 46 to the power supply component 6 at the other end of the heat dissipation pipe 46. The multiple heat dissipation pipes 46 can dissipate heat for the power supply components 6 in different areas at the same time, thereby improving the heat dissipation efficiency of the device. When the temperature of a power supply component 6 in the cabinet 1 rises, the heat-conducting fins 472 connected to the power supply component 6 transfer the temperature to the corresponding regulating tube 471, and the heat dissipation in the regulating tube 471 The expansion medium expands due to heat and pushes the piston with rod 474 to slide downward.

[0045] Furthermore, the trigger device 48 includes a piston cylinder 481, one end of the piston cylinder 481 is connected to an extension cylinder 482, the end of the piston cylinder 481 away from the extension cylinder 482 is connected to a buffer cylinder 483, the inner wall of the piston cylinder 481 is fixedly connected to a heat conductive strip 484, the inner wall of the buffer cylinder 483 is fixedly connected to a plug 485 through an arc spring, the inner wall of the piston cylinder 481 away from the buffer cylinder 483 is slidably connected to a movable piston 486, the end of the movable piston 486 away from the piston cylinder 481 extends to the interior of the extension cylinder 482 and is provided with a groove 487, the inner wall of the groove 487 is fixedly connected to a pressing block 488 through a compression spring, the end of the movable piston 486 close to the groove 487 is fixedly connected to an annular switch sheet 489, a trigger switch 4810 is installed on the inner wall of the extension cylinder 482 near the pressing block 488, and a fixed switch sheet 4811 is installed on the inner wall of the extension cylinder 482 near the trigger switch 4810.

When the high temperature in the cabinet 1 continues and cannot be reduced, the movable piston 486 drives the annular switch piece 489 to contact the fixed switch piece 4811, and the external alarm system is triggered at this time. When the fan 42 is damaged, an alarm is promptly issued to notify the staff to carry out emergency repairs to avoid safety accidents such as fire caused by excessive temperature.
