Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets for low-voltage power supplies, and in particular to an intelligent power distribution cabinet for low-voltage power supplies. Background Art

[0002] The low-voltage power distribution cabinet is an electrical equipment combination device used to distribute and control low-voltage electric energy (generally AC 1000V and below, DC 1500V and below). It distributes the electric energy from the transformer or other power sources to various electrical equipment or branches, and protects, monitors and controls the circuit to ensure the safe, stable and efficient operation of the power system. The low-voltage power distribution cabinet mainly plays the function of electric energy distribution, reasonably distributes the electric energy of the total power supply to different load lines to meet the power needs of various equipment. For example, in a factory workshop, the distribution cabinet distributes the introduced low-voltage power to different machine tools, lighting equipment, ventilation equipment, etc. At the same time, it can protect the circuit from overload, short circuit, undervoltage and other faults.

[0003] During the use of the low-voltage power distribution cabinet, in order to ensure safe and stable power supply operation inside the cabinet, an exhaust component is used to assist in exhausting and cooling the interior of the cabinet. During the exhaust and heat dissipation process, due to the differences in the outer diameters of the cables connected inside the cabinet, for cables with small outer diameters, their own surface area is relatively small, and the heat generated is relatively less. As the outer diameter of the cable increases, the increase in the heat dissipation area per unit length is relatively small, but the heat generated increases significantly. While the low-voltage power distribution cabinet uses heat dissipation components to assist in cooling cables of different sizes, it is unable to perform targeted heat dissipation for cables of different outer diameters, affecting the heat dissipation effect of the low-voltage power distribution cabinet on different cables during power supply use.

[0020] The exhaust assembly includes a mounting cover 201 fixed to the back of the cabinet 101, each set of exhaust slots 104 communicates with the interior of the mounting cover 201, and a fan 202 for exhausting and dissipating heat is installed on the mounting cover 201; It should be noted here that when it is necessary to extract air from the interior of the cabinet 101 to dissipate heat, the fan 202 is started, and through the driving action of the fan 202 and the connection between the air inlet window 103 and the exhaust slot 104, the external air circulates with the interior of the cabinet 101 to achieve the purpose of extracting air and dissipating heat.

[0021] Preferably, the blocking and shielding assembly includes two groups of blocking plates 501 arranged inside the cabinet 101 for blocking the exhaust slot 104, the two groups of blocking plates 501 are against the inner side of the cabinet 101, the upper and lower ends of the blocking plates 501 are fixed with connecting plates 502, and the interior of the cabinet 101 is provided with a sliding assembly for slidingly connecting the connecting plates 502; It should be noted here that: during the entire process of the cable 105 being clamped and arranged, the exhaust slot 104 at the corresponding position is unblocked after the cable 105 is installed, while the exhaust slot 104 at other positions where the cable 105 is not installed remains blocked, so that the exhaust component can more accurately exhaust and dissipate heat at the designated position during the process of exhausting and dissipating heat inside the cabinet 101; It is worth noting here that: initially, the two sets of blocking plates 501 are in a state of blocking each other.

[0022] Preferably, two groups of clamping and wiring assembly are provided, and the two groups of clamping and wiring assembly are symmetrically arranged on the upper and lower sides of the blocking and shielding assembly; It should be noted here that: the two sets of clamping and cable management components are used to ensure the effect of clamping and managing the cable 105.

During the pushing process, the outer side of the cable 105 abuts against the inclined surfaces 303 on the two groups of clamping plates 302. During the abutting process, the two groups of clamping plates 302 are forced to move away from each other. As the cable 105 continues to be pushed and the cable 105 is placed between the two groups of clamping plates 302, the two groups of clamping plates 302 are pushed toward each other by the elastic component and the arc-shaped slot 304 abuts against the outer side of the cable 105, so as to clamp and limit the cable 105, thereby achieving the effect of clamping and managing the connected cable 105, and facilitating the wiring operation of the cable 105 inside the power distribution cabinet for low-voltage power supply. It is worth noting that the heat dissipation holes 305 on the clamping plate 302 facilitate auxiliary heat dissipation operations on the abutting and clamped positions on the cable 105 .

[0024] Preferably, one side of the two sets of clamping plates 302 is provided with an inclined surface 303 for abutting against the outer side of the clamping and limiting cable 105 for transmission; It should be noted here that: the connected cable 105 is pushed toward between the two sets of clamps 302 that clamp the cable management component. During the pushing process, the outer side of the cable 105 abuts against the inclined surfaces 303 on the two sets of clamps 302. During the abutting process, the two sets of clamps 302 are pushed to move away from each other.

[0025] Preferably, the elastic component includes a plurality of sleeves 401 fixed on the fixed plate 301, a slide bar 402 is slidably connected to the sleeve 401, one end of the slide bar 402 is fixed to one side of the clamping plate 302, a spring 403 is sleeved on the outer side of the sleeve 401, and the two ends of the spring 403 are respectively set against the fixed plate 301 and the clamping plate 302, and the opposite sides of the two sets of clamping plates 302 are pressed against each other under the elastic force of each set of springs 403; It should be noted here that: through multiple groups of sleeves 401 and slide rods 402, it is convenient to assist the telescopic connection of the clamping plate 302, and through each group of springs 403, it is convenient to squeeze and push the clamping plate 302.

[0026] Preferably, the control component includes a mounting plate 701 fixed to the lower end of the clamping plate 302, a transmission rack 702 is fixed to the upper end of the connecting plate 502, and a stroke amplification component for assisting in transmission stroke amplification is arranged between the mounting plate 701 and the transmission rack 702; the stroke amplification component includes a gear 802 arranged on one side of the mounting plate 701, and a mounting component for mounting and connecting the gear 802 is arranged on the mounting plate 701, a fixed rack 801 is fixed inside the cabinet 101, the gear 802 is located between the fixed rack 801 and the transmission rack 702, and the gear 802 is meshed with the fixed rack 801 and the transmission rack 702; It should be noted here that: as the clamp plate 302 moves after being subjected to force, the mounting plate 701 and the gear 802 connected to the mounting plate 701 are driven to move synchronously. During the movement of the gear 802, the connecting plate 502 is driven to move under force through the mutual meshing transmission between the gear 802 and the fixed rack 801 and the transmission rack 702. In the process of meshing transmission between the gear 802 and the fixed rack 801 and the transmission rack 702, the meshing transmission realizes the amplification of the stroke. The amplification of the stroke facilitates the more sensitive transmission of the connecting plate 502, and the amplification of the stroke can more effectively distinguish the outer diameter size difference between different cables 105.

[0027] Preferably, the mounting assembly includes a strip plate 901 fixed on the mounting plate 701, a mounting frame 902 is fixed on the strip plate 901, a rotating shaft 903 is rotatably connected to the mounting frame 902, a gear 802 is fixed on the rotating shaft 903, and the gear 802 is concentrically arranged with the rotating shaft 903; It should be noted here that the strip plate 901 , the mounting frame 902 and the rotating shaft 903 facilitate the rotatable mounting connection of the gear 802 .

[0028] Preferably, the sliding assembly includes a guide rod 601 slidably connected to the connecting plate 502, and fixed blocks 602 are fixed at both ends of the guide rod 601, and the fixed blocks 602 are fixed inside the cabinet 101; It should be noted here that the movement of the connecting plate 502 after being subjected to force is guided by the sliding action of the guide rod 601 and the fixing block 602 .

[0029] In this scheme: an intelligent low-voltage power distribution cabinet includes the following steps: During the use of the low-voltage power distribution cabinet, auxiliary power supply operation is performed through the connection of multiple groups of cables 105 inside the cabinet 101. After the cables 105 are installed and connected, in order to facilitate the arrangement of the cables 105, the cables 105 are arranged and arranged by two groups of clamping and wiring components. During the arrangement and arrangement process, the connected cables 105 are pushed toward between the two groups of clamping and wiring components. During the pushing process, the outer side of the cable 105 abuts against the inclined surfaces 303 on the two groups of clamping plates 302. During the abutting process, the two groups of clamping plates 302 are pushed to move away from each other. As the cable 105 continues to be pushed and the cable 105 is placed between the two groups of clamping plates 302, the two groups of clamping plates 302 are pushed toward each other by the elastic component and the arc-shaped slot 304 abuts against the outer side of the cable 105, so as to clamp and limit the cable 105, thereby achieving the effect of clamping and wiring the connected cables 105, and facilitating the wiring operation of the cables 105 inside the low-voltage power distribution cabinet. During the process of clamping and arranging the cable 105 by the clamping and arranging assembly, the cable 105 after clamping acts on the two sets of clamping plates 302 to limit the position of the two sets of clamping plates 302, so that the two sets of clamping plates 302 are pushed from the initial state of abutting each other to a state of having a gap (see FIG. Fig.10 and Fig.11 ), in this process, through the transmission action of the control component and the stroke amplification component, the two groups of connecting plates 502 and the blocking plates 501 are synchronously moved away from each other, and through the movement of the two groups of blocking plates 501 away from each other, the two groups of blocking plates 501 no longer block the exhaust groove 104 at the cable 105 clamping and wiring position. Therefore, during the entire cable 105 clamping and wiring operation, the cable 105 is clamped and the wiring is installed, and the exhaust groove 104 at the corresponding position is synchronously released, while the exhaust groove 104 at other positions where the cable 105 is not installed is The sealed state is still maintained, so that the exhaust component can more accurately exhaust and dissipate heat at a designated position during the process of exhausting and cooling the cabinet 101. In the process of synchronously moving the blocking plates 501 away from each other by generating a gap between the two groups of clamping plates 302, when the outer diameter of the cable 105 clamped by the cable management increases, the gap generated between the two groups of clamping plates 302 increases through the outer size of the cable 105 itself. In the process of increasing, the distance between the two groups of blocking plates 501 is synchronously increased through transmission (see Fig.11 ), so in the process of clamping and arranging the cable 105, the larger the outer diameter of the cable 105, the larger the opening spacing between the two sets of blocking plates 501 through transmission, so that in the process of power supply and heat dissipation, the low-voltage power distribution cabinet can control the size of the heat dissipation opening spacing according to the size of the outer diameter of the cable 105, and perform heat dissipation in a targeted manner, while ensuring the heat dissipation effect of different cables 105, making the low-voltage power distribution cabinet more intelligent in the process of power supply and heat dissipation; In the process of transmitting the connection plate 502 and the blocking plate 501 by the gap between the two groups of clamping plates 302, as the clamping plate 302 moves after being stressed, the mounting plate 701 and the gear 802 connected to the mounting plate 701 are driven to move synchronously. In the process of the movement of the gear 802, the gear 802 is meshed with the fixed rack 801 and the transmission rack 702 to drive the connection plate 502 to move under stress (see FIG. 1 ). Fig. 9 In the transmission process of the gear 802, the fixed rack 801 and the transmission rack 702 are meshed and transmitted. When the gear 802 rotates, the fixed rack 801 remains in position. Under the constraint of the fixed rack 801, the rotational motion of the gear 802 causes the meshed transmission rack 702 to produce a linear motion. Assuming that the radius of the gear 802 is R and the number of teeth is Z, when the rotation angle of the gear 802 is θ (radians), the arc length of the gear 802 is L1=Rθ. According to the meshing relationship, the distance moved by the transmission rack 702 is L2=MZθ / 2π (where M is the module). Since MZ>2πR, the stroke of the transmission rack 702 is greater than the arc length of the gear 802, thereby achieving stroke amplification. The amplification of the stroke facilitates more sensitive transmission of the connecting plate 502, and the outer diameter size difference between different cables 105 can be more effectively distinguished through the stroke amplification.
