DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] Embodiment 1:

[0038] A highly efficient and energy-saving power distribution cabinet, such as Figure 1-Figure 9 As shown, it includes a cabinet body 1 and a cabinet door 5 rotatably connected to the opening of the cabinet body 1, the interior of the cabinet body 1 is provided with a mounting frame 4 for installing electrical components, the side wall of the cabinet body 1 is provided with a cooling fan 3, and the interior of the cabinet body 1 is provided with a partition control unit 2 for controlling the power of the cooling fan 3.

[0039] In this embodiment, the number and position of the cooling fans 3 are not limited. Preferably, the cooling fans 3 are four groups, which are respectively located above and below the symmetrical sides of the cabinet 1 .

[0040] The partition control part 2 includes a hollow shell 6, a magnetic core 11 and a hollow cover plate 12. The hollow shell 6 is fixed to the inner wall of the cabinet 1 by bolts, and the hollow cover plate 12 is fixed to the opening of the hollow shell 6 by bolts. The magnetic core 11 is fixed to the inside of the hollow shell 6 by an insulating frame. The outer wall of the hollow shell 6 is respectively wound with multiple groups of secondary coils 7 and primary coils 10. The number of secondary coils 7 and primary coils 10 is the same, and the number of groups corresponds to the number of groups of the cooling fan 3. The primary coil 10 is connected to an AC power supply. The side wall of the secondary coil 7 is matched and electrically conductively connected with an electrode head 8. The outer end of the secondary coil 7 and the electrode head 8 are respectively connected to the power supply terminal of the cooling fan 3. The side wall of the hollow shell 6 is provided with a telescopic control component 9 for controlling the position of the electrode head 8.

[0041] The plurality of telescopic control components 9 are respectively close to an area where a group of cooling fans 3 are located.

[0042] When the device is in use, the AC power supply of the primary coil 10 is started, an alternating magnetic field is generated in the magnetic core 11, and then an induced electromotive force is generated in the secondary coil 7 according to electromagnetic induction, so that the induced electromotive force is used to power the cooling fan 3. When the cooling fan 3 is started, the hot air in the cabinet 1 can be blown out, and then cool air is sucked in from the outside through negative pressure to achieve heat dissipation. Moreover, since the induced electromotive force generated by the secondary coil 7 is related to the number of turns connected thereto, the position of the electrode head 8 can be controlled by the telescopic control component 9 to control the number of turns connected to the secondary coil 7, thereby controlling the power of the cooling fan 3 in turn.

[0043] This device, by utilizing the principle of electromagnetic induction, can control the number of connected turns of the secondary coil 7 by the position of the electrode head 8, thereby controlling the power of the cooling fan 3, so that the cooling power of the cooling fan 3 matches the heat generation efficiency, which not only ensures reliable heat dissipation, but also achieves energy-saving effects. At the same time, by arranging multiple groups of cooling fans 3, which are located at different positions, the cooling can be controlled by zones according to the different temperatures of various areas in the cabinet 1, thereby further increasing the use effect.

[0044] In order to solve the adaptive control problem; such as Figure 3 As shown, the telescopic control assembly 9 includes a heat-conducting tube 16 fixedly embedded in the hollow shell 6 and a cylinder body 14 fixed and connected to the heat-conducting tube 16, the inner wall of the cylinder body 14 is slidably connected to a piston 15, the side wall of the piston 15 is fixed to a connecting rod 13, and the electrode head 8 is fixed to the side wall of the connecting rod 13.

[0045] Since the heat pipe 16 is close to the corresponding heat dissipation fan 3, when the temperature of the area where the heat dissipation fan 3 is located increases, the internal temperature of the heat pipe 16 will also increase, so that the gas will expand due to the heat and increase in volume, thereby pushing the piston 15 to move, and then driving the electrode head 8 to slide through the connecting rod 13, so that the number of turns of the secondary coil 7 increases, and the heat dissipation power of the heat dissipation fan 3 increases, and vice versa.

[0046] This device, based on the principle of thermal expansion and contraction of gas, combined with the cooperation of the cylinder 14 and the piston 15, can achieve adaptive matching of the heat dissipation efficiency and actual temperature of each area on the basis of zoning control, without the need for manual or algorithmic control, thus simplifying the control logic.

[0047] In order to solve the protection problem; Figure 4 , 5 As shown, a backflow prevention component 17 is arranged on the outer side of the heat dissipation fan 3 , and the backflow prevention component 17 includes a frame 18 fixed to the outer wall of the cabinet 1 and a plurality of rotating plates 19 rotatably connected to the ends of the frame 18 .

[0048] Since the environment of the power plant is relatively dirty and messy, there will be a lot of dust in the air. In order to prevent dust from entering the cabinet 1 and causing malfunctions, the device is provided with a frame 18 and a rotating plate 19. When the cooling fan 3 is working, the rotating plate 19 will be rotated open by the force of the airflow to ensure heat dissipation. When the cooling fan 3 is not working, the rotating plate 19 is rotated downward and closed by gravity, thereby preventing dust from backflowing into the cabinet 1 and reducing the malfunction rate caused by dust.

[0049] To further solve the problem of dust ingress; Figure 6 , 7 As shown, a self-cleaning filter assembly 20 is provided at the back air inlet of the cabinet 1, and the self-cleaning filter assembly 20 includes an outer shell 21 and a pleated filter element 28. The outer shell 21 is fixed to the outer wall of the air inlet of the cabinet 1 by bolts, and the inner wall of the outer shell 21 is provided with an upper and lower and left-right symmetrical inclined groove 25. The inner walls of the two left-right symmetrical inclined grooves 25 are slidably connected to a mounting plate 27 through a limiting column 24, and the pleated filter element 28 is fixed to the opposite side of the two mounting plates 27.

[0050] The inner wall of the inclined slide groove 25 is elastically connected to an arc head protrusion 23 which is limitedly matched with the limiting column 24 through a spring 22 .

[0051] A baffle 26 is fixed to the inner wall of the housing 21 .

[0052] When air enters the air inlet of the cabinet 1, the pleated filter element 28 can filter, and during filtering, the pleated filter element 28 will also be subjected to the force of gas, so that the limiting column 24 is located at the inner end of the inclined slide 25, and at this time, the limiting column 24 cooperates with the arc surface of the arc head protrusion 23, and the mounting plate 27 fits with the baffle 26 to prevent unfiltered gas from entering from the gap. When closed, due to the matching of the limiting column 24 with the arc surface of the arc head protrusion 23, the limiting column 24 will be subjected to the force acting outward and rebound. When rebounding, due to the guidance of the inclined slide 25, the two mounting plates 27 will move away from each other, so that the pleated filter element 28 pleats open, and then the limiting column 24 moves to the outer end of the inclined slide 25 and collides, and the opened pleated filter element 28 is cleaned by the collision vibration.

[0053] The device, by providing a pleated filter element 28, can filter the incoming air to further prevent dust from entering, and by providing an arc head protrusion 23, the arc surface can be used to make the mounting plate 27 rebound in a non-filtering state, and the vibration generated by the collision can be used to achieve the purpose of self-cleaning, and by providing an inclined slide groove 25, the guide energy can be used to make the pleats of the pleated filter element 28 open during self-cleaning, thereby increasing the cleaning effect.

[0054] When the present embodiment is in use, the AC power supply of the primary coil 10 is started, an alternating magnetic field is generated in the magnetic core 11, and an induced electromotive force is generated in the secondary coil 7 according to electromagnetic induction, so that the induced electromotive force is used to power the cooling fan 3. When the cooling fan 3 is started, the hot air in the cabinet 1 can be blown out, and then cool air is sucked in from the outside through negative pressure to achieve heat dissipation. Moreover, since the induced electromotive force generated by the secondary coil 7 is related to the number of connected turns, the position of the electrode head 8 can be controlled by the telescopic control component 9 to control the number of connected turns of the secondary coil 7, thereby controlling the power of the cooling fan 3 in turn. Moreover, since the heat pipe 16 is close to the corresponding cooling fan 3, when the temperature of the area where the cooling fan 3 is located increases, the internal temperature of the heat pipe 16 will also increase, so that the air The body expands due to heat, and its volume increases, thereby pushing the piston 15 to move, and then driving the electrode head 8 to slide through the connecting rod 13, so that the number of turns of the secondary coil 7 increases, and the heat dissipation power of the cooling fan 3 increases, and vice versa. At the same time, when air enters the air inlet of the cabinet 1, the pleated filter element 28 can filter, and during filtering, the pleated filter element 28 will also be affected by the gas force, so that the limit column 24 is located at the inner end of the inclined slide groove 25, and at this time the limit column 24 cooperates with the arc surface of the arc head protrusion 23, and at this time the mounting plate 27 is fitted with the baffle 26 to prevent unfiltered gas from entering from the gap. When closed, due to the cooperation between the limit column 24 and the arc surface of the arc head protrusion 23, the limit column 24 will be subject to the outward force and rebound, and when rebounding, due to the guidance of the inclined slide groove 25. The two mounting plates 27 will move away from each other, so that the pleated filter element 28 pleats open, and then the limiting column 24 moves to the outer end of the inclined slide groove 25 to collide, and the opened pleated filter element 28 is cleaned by the collision vibration.

[0055] Embodiment 2:

[0056] A highly efficient and energy-saving power distribution cabinet, such as Figure 1 , 8 , 9, in order to solve the installation problem; this embodiment makes the following improvements on the basis of embodiment 1: the mounting frame 4 includes a cross bar 32 slidably connected to the inside of the cabinet 1 through a guide rod 33 and a plurality of longitudinal bars 31 slidably connected to the outer wall of the cross bar 32 in a transverse direction.

[0057] The side wall of the longitudinal rod 31 is provided with a plurality of mounting holes 30 for mounting electrical components, and the side wall of the longitudinal rod 31 at the cross rod 32 is provided with a threaded hole 29 .

[0058] When in use, the electrical components can be installed through the mounting holes 30, and the longitudinal rod 31 can be slid to adjust the distance between adjacent electrical components and the overall installation layout. After the adjustment is completed, the bolts can be screwed into the threaded holes 29, and the position of the longitudinal rod 31 can be locked by utilizing the friction between the bolts and the cross rod 32.

[0059] The device is provided with a longitudinal rod 31 and a transverse rod 32, and uses the longitudinal rod 31 to install electrical components, so that during installation, the installation spacing of the electrical components can be specifically adjusted according to the volume of the electrical components, thereby optimizing the overall installation layout.

[0060] A reel 35 is fixedly embedded in the inner wall of the cabinet door 5, and a rope 34 is wound around the outer wall of the reel 35. One end of the rope 34 is fixed to one side of the cross bar 32, and the other side of the reel 35 passes through the inner wall of the cabinet body 1 and is connected to the other side of the cross bar 32.

[0061] When the cabinet door 5 rotates to open, the reel 35 will move accordingly, thereby driving the rope 34 to move, and the rope 34 is used to pull the cross bar 32 to pull the cross bar 32 outward. When the cabinet door 5 rotates to close, the reel 35 drives the rope 34 to move in the opposite direction, and then pulls the cross bar 32 into the interior of the cabinet body 1.

[0062] This device is based on the design of the cross bar 32 and the guide rod 33, so that the cross bar 32 can slide relatively, so that when the electrical components are secured and disassembled, the longitudinal rod 31 is relatively located on the outside, which increases convenience, and by providing a twisted rope 34 and a reel 35, the position of the cross bar 32 can be synchronized with the position of the cabinet door 5, thereby increasing the synchronous linkage.

[0063] When the present embodiment is in use, the electrical components can be installed through the mounting holes 30, and the longitudinal rod 31 can be slidably adjusted to adjust the distance between adjacent electrical components and the overall mounting layout. After the adjustment is completed, the bolt can be screwed into the threaded hole 29, and the position of the longitudinal rod 31 can be locked by utilizing the friction between the bolt and the cross rod 32. In addition, when the cabinet door 5 is rotated to open, the reel 35 will move accordingly, thereby driving the twisted rope 34 to move, and the cross rod 32 is pulled by the twisted rope 34 to pull the cross rod 32 outward. When the cabinet door 5 is rotated to close, the reel 35 drives the twisted rope 34 to move in the opposite direction, and then pulls the cross rod 32 into the interior of the cabinet body 1.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
