Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an explosion-proof power distribution cabinet for intelligent power applications. Background Technology

[0002] In many industrial environments with flammable and explosive hazards, such as petrochemical, coal mining, and natural gas processing facilities, explosion-proof distribution cabinets are required for power distribution and control. While traditional explosion-proof distribution cabinets can prevent explosions caused by internal electrical faults from harming the external environment to some extent, they have several shortcomings. For example, their heat dissipation performance is poor, and prolonged operation can lead to heat buildup that may affect the performance and lifespan of electrical components; they lack precise monitoring and intelligent control capabilities for internal electrical parameters, making it difficult to promptly detect potential faults and take effective measures; the sealing structure of the cabinet door is not perfect, allowing flammable and explosive gases to seep in under complex environments; and the explosion-proof structural design needs improvement in its ability to release explosive impact forces, making it difficult to comprehensively guarantee safety and stable equipment operation. Therefore, this paper presents an intelligent explosion-proof power distribution cabinet. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an intelligent explosion-proof power distribution cabinet. L-shaped heat dissipation fins dissipate heat accumulated at the top of the cabinet, and a cooling fan accelerates the heat dissipation of the fins, thus cooling the cabinet. Simultaneously, serpentine heat exchange tubes further enhance the cooling effect by facilitating heat exchange inside the cabinet. Through the combined use of a pressure relief port, T-pin, sealing baffle, and spring, in the event of an explosion, high-pressure gas forces the sealing baffle open and releases the pressure through the pressure relief port, significantly preventing the cabinet door from being blown open and causing debris to fly, thus avoiding serious injury to surrounding equipment and personnel. This overcomes the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An explosion-proof power distribution cabinet for intelligent power applications includes a cabinet body. L-shaped heat dissipation fins are fixed at equal intervals on one outer wall and the top outer wall of the cabinet body. A cabinet door is provided on the other side of the cabinet body. A sealing ring is fixed at the inner edge of the cabinet door. A pressure relief port is provided at the bottom of the cabinet door. A support partition is fixed on one side of the bottom of the inner wall of the cabinet body. A support leg is fixed between the support partition and the bottom inner wall of the cabinet body. A serpentine heat exchange tube is fixed on the lower end face of the support partition. Both ends of the serpentine heat exchange tube extend to the outside of the cabinet body and are connected to a water cooling device.

[0006] As a further improvement of this utility model: each of the L-shaped heat dissipation fins has a chamfer at its outer corner, and a mounting plate is fixed at the chamfer. The mounting plate has mounting holes at equal intervals, and a cooling fan is installed at each mounting point.

[0007] As a further embodiment of this utility model: a temperature sensor is fixed on the inner wall of the power distribution cabinet, and a controller module is installed on one outer wall of the power distribution cabinet. The cooling fan and the temperature sensor are both electrically connected to the controller module, and the controller module is electrically integrated with a display screen, control buttons and a communication module.

[0008] As a further improvement of this utility model, heat dissipation holes are provided at equal intervals on the L-shaped heat dissipation fins.

[0009] As a further improvement of this utility model: connecting rods are fixed at the four corners of the side of the mounting plate facing the power distribution cabinet, and the four connecting rods are welded to the outer wall of the power distribution cabinet.

[0010] As a further improvement of this utility model: heat conduction holes are provided at equal intervals on the support partition, and threaded connection holes are provided at the four corners of the support partition.

[0011] As a further improvement of this utility model: T-shaped pins are movably inserted into the four corners of the cabinet door and located at the pressure relief port. A sealing baffle is connected to one end of the four T-shaped pins on the outside of the cabinet door, and a spring is sleeved on the part of the four T-shaped pins on the inside of the cabinet door.

[0012] As a further improvement of this utility model: support columns are fixed at the four corners of the lower end face of the power distribution cabinet, and L-shaped air guide plates are fixed at the lower ends of the four support columns.

[0013] As a further improvement of this utility model: a wire hole is provided on the bottom side of the distribution cabinet for cables to pass through, and a sealing gasket and an explosion-proof gland are installed at the wire hole.

[0014] The beneficial effects of this utility model are as follows:

[0015] The L-shaped heat dissipation fins can dissipate heat from the top of the power distribution cabinet, and the cooling fan accelerates the heat dissipation of the L-shaped heat dissipation fins to cool the power distribution cabinet. At the same time, the serpentine heat exchange tubes are used to exchange heat inside the power distribution cabinet to further improve the cooling effect. Through the combination of the pressure relief port, T-pin, sealing baffle and spring, in the event of an explosion, the high pressure will push the sealing baffle open and release it from the pressure relief port, which largely avoids the cabinet door being blown open and fragments flying, and avoids serious injury to surrounding equipment and personnel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 An explosion-proof power distribution cabinet for intelligent power applications includes a cabinet body 1. L-shaped heat dissipation fins 8 are fixed at equal intervals on one side outer wall and the top outer wall of the cabinet body 1. Heat dissipation holes 5 are opened at equal intervals on the L-shaped heat dissipation fins 8. A cabinet door 4 is provided on the other side of the cabinet body 1. A sealing ring 13 is fixed at the inner edge of the cabinet door 4. A pressure relief port 14 is opened at the bottom of the cabinet door 4. A support partition 17 is fixed on one side of the bottom inner wall of the cabinet body 1. A support leg is fixed between the support partition 17 and the bottom inner wall of the cabinet body 1. A serpentine heat exchange tube 9 is fixed on the lower end face of the support partition 17. Both ends of the serpentine heat exchange tube 9 extend to the outside of the cabinet body 1 and are connected to a water cooling device. A wire hole for cables to pass through is opened on one side bottom of the cabinet body 1. A sealing gasket and an explosion-proof gland 10 are installed at the wire hole to ensure the explosion-proof performance of the cable connection.

[0023] Each L-shaped heat dissipation fin 8 has a chamfered corner at its external angle, and a mounting plate 6 is fixed at the chamfered corner. Mounting holes are evenly spaced on the mounting plate 6, and a cooling fan 7 is installed at each mounting point.

[0024] A temperature sensor 15 is fixed on the inner wall of the power distribution cabinet 1. A controller module 16 is installed on one outer wall of the power distribution cabinet 1. The cooling fan 7 and the temperature sensor 15 are electrically connected to the controller module 16. The controller module 16 is electrically integrated with a display screen, control buttons and a communication module.

[0025] The mounting plate 6 is fixed with connecting rods 2 at each of the four corners on the side facing the power distribution cabinet 1. All four connecting rods 2 are welded to the outer wall of the power distribution cabinet 1.

[0026] Heat conduction holes 18 are provided at equal intervals on the support partition 17, and threaded connection holes are provided at the four corners of the support partition 17.

[0027] T-shaped pins 19 are movably inserted into the four corners of the cabinet door 4 and the pressure relief port 14. The four T-shaped pins 19 are connected to a sealing baffle 3 at the outer end of the cabinet door 4, and springs 20 are fitted on the inner part of the four T-shaped pins 19.

[0028] The components inside the power distribution cabinet 1 can be installed on the support partition 17. The threaded connection holes of the support partition 17 can be used to connect the components. The heat in the power distribution cabinet 1 will accumulate on the top of the inner wall of the power distribution cabinet 1. The heat in the power distribution cabinet 1 can be discharged through the L-shaped heat dissipation fins 8. The coolant in the serpentine heat exchange tube 9 is circulated by the external water cooling device. The serpentine heat exchange tube 9 exchanges heat inside the power distribution cabinet 1 and further carries away the heat. The temperature sensor 15 detects the temperature inside the power distribution cabinet 1 and transmits the temperature signal to the controller module 16. When the temperature is too high, the controller module 16 controls the cooling fan 7 to turn on. The cooling fan 7 blows air to the horizontal and vertical sections of the L-shaped heat dissipation fins 8 to cool down and improve the heat dissipation effect of the cabinet. The temperature information can be transmitted to the remote terminal used by the staff through the communication module so that the staff can understand the temperature information of the power distribution cabinet 1 in time.

[0029] When an explosion occurs inside the distribution cabinet 1, the air inside the distribution cabinet 1 expands rapidly, and the air pressure pushes open the sealing baffle 3, moving the sealing baffle 3 away from the pressure relief port 14. At the same time, the four springs 20 are compressed, and the high-pressure gas is discharged from the pressure relief port 14 to relieve pressure. This largely avoids the cabinet door 4 being blown open and causing fragments to fly, thus avoiding serious injury to surrounding equipment and personnel.

[0030] Example 2 is an optimization based on Example 1, specifically:

[0031] Support columns 12 are fixed at the four corners of the lower end face of the power distribution cabinet 1, and L-shaped air guide plates 11 are fixed at the lower ends of the four support columns 12.

[0032] When the cooling fan 7 blows air to cool the vertical section of the L-shaped heat dissipation fins 8, the hot air can be discharged along the L-shaped air guide plate 11, so that the hot air is away from the power distribution cabinet 1, and the heat is prevented from flowing back to the vicinity of the cooling fan 7, which would reduce the cooling effect.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
