Description

Technical Field

[0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet with a heat dissipation function. Background Art

[0002] A power distribution cabinet is a device used to distribute power resources, protect circuits and control the operation of electrical equipment. It is equipped with various electrical components such as circuit breakers, contactors, relays, instruments, etc., which are used to achieve the normal operation and fault protection of the power system. The power distribution cabinet with heat dissipation function is designed to solve the problems caused by the heat generated by the internal electrical components during operation. If the heat is not dissipated in time, it may cause the electrical components to overheat, resulting in performance degradation, shortened life and even safety accidents. Therefore, the heat dissipation function is crucial to ensure the safe and reliable operation of the power distribution cabinet.

[0003] The existing power distribution cabinet with heat dissipation function blows air into the interior of the power distribution cabinet through the rotating impellers of multiple fans, and takes away the heat in the power distribution cabinet through the opened heat dissipation slots, so as to dissipate the heat of the electrical components inside the power distribution cabinet. However, although there are multiple fans, their positions are fixed, which will cause good heat dissipation in some areas and insufficient heat dissipation in other areas, forming local hot spots. This uneven heat dissipation will cause key electrical components to overheat, affecting their performance and life. At the same time, due to uneven heat dissipation, a large temperature gradient will appear inside the power distribution cabinet, which will not only affect the working stability of electronic components, but also easily accelerate the aging of materials and shorten the service life of equipment. In order to ensure that the temperature in the entire power distribution cabinet is within a safe range, personnel are required to add more fans or increase the fan speed, which will increase energy consumption and do not meet the requirements of energy conservation and emission reduction. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies of the prior art and provides a power distribution cabinet with a heat dissipation function. The position of the fan can be moved while cooperating with the condenser to cool the wind blown by the hair dryer to dissipate heat for the electrical components inside the power distribution cabinet.

A fan is arranged inside, a rotating seat is arranged on the relative inner side surfaces of the two mounting frames, and two connecting frames are rotatably arranged inside the rotating seats. Two screw rods corresponding to the left and right positions are rotatably arranged inside the mounting shell, and the left and right thread directions of the two screw rods are opposite. The rotating frames are threadedly connected to the outer sides of the two screw rods, and the ends of the two connecting frames away from the rotating seats are respectively rotatably connected to the adjacent rotating frames. An electric drive unit 1 for driving the screw rods to rotate is arranged inside the mounting shell, and the electric drive unit 1 includes a mounting plate arranged inside the mounting shell, and a double-axis motor is arranged on the rear side of the mounting plate, and the output shafts on the left and right sides of the double-axis motor are respectively connected to the relative inner ends of the two screw rods through couplings, a condenser is arranged on the inner rear side of the cabinet, and a plurality of fins distributed at equal intervals are also arranged on the inner rear side of the cabinet, and circular holes matching the condenser are opened inside the plurality of fins.

[0006] As a further improvement of the present invention, the quick-disassembly protection mechanism includes a filter plate slidably arranged inside the mounting shell, two locking columns are slidably arranged on the left and right sides of the mounting shell, two locking holes are opened on the left and right sides of the filter plate, and multiple locking columns are respectively plugged into the locking holes. A pull plate is arranged between the outer ends of two adjacent locking columns, and the locking column and the pull plate are fixed by welding. An elastic driving unit is arranged between the pull plate and the mounting shell, and the elastic driving unit includes a spring arranged thereon, and the multiple springs are respectively sleeved on the outer arc surfaces of the corresponding locking columns.

[0007] As a further improvement of the present invention, the heat dissipation angle adjustment mechanism includes a plurality of adjustment plates which are arranged inside the cabinet through rotation of a rotating column, gears are arranged on the outer arc surfaces of the plurality of rotating columns, the plurality of gears are connected by a toothed belt pulley, and an electric drive unit 2 for driving the rotating column to rotate is arranged at the lower left end of the cabinet, the electric drive unit 2 includes a motor arranged at the lower left end of the cabinet, and the output shaft of the motor is connected to the left end of the lowest rotating column through a coupling.

[0008] As a further improvement of the present invention, a control panel is provided on the front side of the cabinet door, and the motor, the dual-axis motor and the fan are all electrically connected to the control panel.

[0009] As a further improvement of the present invention, a support frame is provided at the lower end of the cabinet, the support frame and the cabinet are fixed by welding, and a plurality of support feet are provided at the lower end of the support frame, and the plurality of support feet are respectively located at the four corners of the lower end of the support frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, use the handle to open the cabinet door, install the electrical components into the cabinet through the mounting holes on the frame plate, and enter the cables into the cabinet through the cable entry holes at the top of the cabinet to connect to the electrical components. Then close the cabinet door with the handle, and observe the indicator lights of the electrical components inside the cabinet through the observation window. Then, turn on the fan through the control panel, and the impeller rotates to blow outside air into the distribution cabinet, taking away the heat in the distribution cabinet through the heat dissipation slots, so as to quickly dissipate the heat of the electrical components inside the distribution cabinet.

[0012] Secondly, the dual-axis motor is turned on through the control panel, and the output shaft drives the screw rods on both sides to rotate. Since the screw rods on both sides have opposite threads, the rotating frames on both sides are driven to move closer or farther away from each other, so that the connecting frames on both sides rotate to gather or expand, and then drive the fans inside the mounting frames on the rotating seats on both sides to move closer or farther away from each other, which can evenly and comprehensively dissipate the heat of the electrical components inside the cabinet. The personnel can connect the condenser to the external coolant circulation water tank to allow the cooling to enter the internal circulation of the condenser, and cooperate with the fins to expand the cooling area, and then cooperate with the wind blown by the fan to become cold wind to dissipate the heat of the electrical components inside the cabinet, thereby more efficiently realizing the heat dissipation of the electrical components inside the distribution cabinet. The position of the fan can be moved while cooperating with the condenser to cool the wind blown by the hair dryer to dissipate the heat of the electrical components inside the distribution cabinet, which can ensure that the heat dissipation cold airflow covers all key parts that need heat dissipation, make the temperature of each part inside the distribution cabinet more balanced, eliminate heat dissipation dead corners, improve the overall heat dissipation efficiency, help improve the reliability and stability of electronic components, and reduce energy consumption.

[0013] Thirdly, the motor is turned on through the control panel, the output shaft drives the lower adjustment plate to rotate, and then the toothed belt drives the adjustment plates on the remaining gears to rotate through the lower gears, so that the wind blown out by the fan further covers every corner of the electrical components inside the distribution cabinet and fully dissipates the heat.

[0014] Fourthly, the wind that enters the cabinet through the fan can filter the dust in the air through the filter plate to prevent dust from entering the interior of the distribution cabinet and polluting the electrical components. When the filter plate is over-accumulated with dust and needs to be disassembled for cleaning and replacement, the pull plates on both sides are pulled to make the locking columns on both sides leave the locking holes on the filter plate, thereby releasing the lock on the filter plate. At this time, the spring is in a stretched state, and the filter plate can then be taken out. Then the new filter plate is slid into the interior of the mounting shell so that the locking holes correspond to the positions of the locking columns, and the pull plate is released. At this time, the spring rebounds quickly to drive the locking columns to be inserted into the locking holes, thereby realizing quick replacement of the filter plate and facilitating maintenance.

[0015] Fifthly, the support frame and the support feet can provide stable support for the power distribution cabinet, ensuring that the electrical components and heat dissipation mechanisms inside the power distribution cabinet operate more stably, greatly improving the heat dissipation quality of the electrical components inside the power distribution cabinet.

Two screw rods 209 corresponding to left and right positions are rotatably arranged inside the installation shell 201. The left and right thread directions of the two screw rods 209 are opposite. The outer surfaces of the two screw rods 209 are threadedly connected with rotating frames 208. The ends of the two connecting frames 207 away from the rotating seats 206 are respectively connected to the inner rotation of the adjacent rotating frames 208.

[0027] like Figure 1 , 6 As shown, the quick-disassembly protection mechanism includes a filter plate 304 slidably arranged inside the mounting shell 201, two locking columns 302 are slidably arranged on the left and right sides of the mounting shell 201, two locking holes are provided on the left and right sides of the filter plate 304, and a plurality of locking columns 302 are respectively plugged into the locking holes, a pull plate 301 is provided between the outer ends of two upper and lower adjacent locking columns 302, an elastic driving unit is provided between the pull plate 301 and the mounting shell 201, and the elastic driving unit includes a spring 303, and a plurality of springs 303 are respectively sleeved on the outer arc surfaces of the corresponding locking columns 302.

[0028] like Figure 1 As shown, a control panel 103 is disposed on the front side of the cabinet door 102 , and the motor 205 , the dual-axis motor 211 and the fan 214 are all electrically connected to the control panel 103 .

[0029] The cabinet door 102 is opened by the handle, and the electrical components are installed into the cabinet 101 through the mounting holes on the frame plate 107. The cables can enter the cabinet 101 through the wire entry hole 106 at the upper end of the cabinet 101 and connect to the electrical components. Then the cabinet door 102 is closed by the handle. The personnel can observe the indicator lights of the electrical components inside the cabinet 101 through the observation window, and then the fan 214 is turned on through the control panel 103. The impeller rotates to blow external air into the interior of the distribution cabinet, and the heat in the distribution cabinet is taken away through the heat dissipation slots 105, so as to achieve heat dissipation of the electrical components inside the distribution cabinet.

[0030] The control panel 103 can also be used to control the opening of the dual-axis motor 211, and the output shaft drives the screw rods 209 on both sides to rotate. Since the thread directions of the screw rods 209 on both sides are opposite, the rotating frames 208 on both sides are driven to move closer or farther away from each other, so that the connecting frames 207 on both sides rotate to gather or expand, and then drive the fans 214 inside the mounting frames 215 on the rotating seats 206 on both sides to move closer or farther away from each other, so that the electrical components inside the cabinet 101 can be evenly and comprehensively dissipated.

[0032] The wind that enters the cabinet 101 through the fan 214 can filter the dust in the air through the filter plate 304 to prevent the dust from entering the interior of the distribution cabinet and polluting the electrical components. When the filter plate 304 is overfilled with dust and needs to be disassembled for cleaning and replacement, the pull plates 301 on both sides are pulled so that the locking columns 302 on both sides leave the locking holes on the filter plate 304, thereby releasing the lock on the filter plate 304. At this time, the spring 303 is in a stretched state, and then the filter plate 304 can be taken out, and the new filter plate 304 is slid into the interior of the mounting shell 201 so that the locking holes correspond to the positions of the locking columns 302, and then the pull plate 301 is released.
