[0025] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0026] Embodiment 1: As shown in the attached Figure 1 As attached Figure 3 A power distribution cabinet that is easy to clean includes a power distribution cabinet body 1 for accommodating electrical components and wires, and a heat dissipation component arranged in the power distribution cabinet body 1.

[0027] The power distribution cabinet body 1 comprises two parts, namely a cabinet body 27 with a side opening and a cabinet door 24 hingedly connected to the cabinet body 27 to achieve an opening and closing function. The heat dissipation component comprises a motor 26 and a fan 10.

[0028] In order to facilitate cleaning of the heat dissipation assembly, the heat dissipation assembly is detachably installed in the power distribution cabinet body 1 through the installation assembly. The installation assembly includes a mounting frame 8, two movable plates 4, a first wedge block 7, a second wedge block 9, two sets of drive assemblies, etc.

[0029] The mounting frame 8 has a cavity, which includes three plates, namely a horizontal bottom plate and side plates vertically arranged on two opposite sides of the bottom plate, so that the formed cavity is connected to the inside of the power distribution cabinet body 1. The outer bottom surface of the mounting frame 8 is also provided with a handle 23, and the surface of the handle 23 can be provided with an anti-slip cover. The setting of the handle 23 can facilitate the disassembly of the heat dissipation component, and avoid the phenomenon of dropping it when disassembling without holding it, which brings convenience to the user. The heat dissipation component is arranged in the cavity of the mounting frame 8, and the motor 26 is installed on the bottom plate, and its output shaft is arranged vertically upward, and then the fan 10 is fixedly connected to the output shaft of the motor 26.

[0030] The two movable plates 4 are arranged on both sides of the mounting frame 8 in the horizontal direction, that is, outside the two side plates of the mounting frame 8. The movable plates 4 can reciprocate horizontally within a limited range based on the initial position. The driving components correspond to the movable plates 4 one by one, so as to enable the movable plates 4 to realize horizontal reciprocating motion.

[0031] Specifically, the movable plate 4 is arranged longitudinally. Each set of driving components includes a fixed plate 2 and a spring 3. The fixed plate 2 is fixedly arranged in the power distribution cabinet body 1, and is L-shaped and includes a longitudinal part and a transverse part. The transverse part extends from the longitudinal part connected to it to one side of the corresponding movable plate 4, and the upper end of the longitudinal part of the fixed plate 2 is fixed to the top of the power distribution cabinet body 1. Each set of driving components includes two springs 3 arranged longitudinally, and the spring 3 is retracted in the horizontal direction, one end of which is connected to the fixed plate 2, and the other end is connected to the movable plate 4. Therefore, when the spring 3 is retracted horizontally, the movable plate 4 can move horizontally relative to the fixed plate 2. A slide groove 29 can also be provided on the transverse part of the fixed plate 2, and a movable rod is connected to the lower end of the movable plate 4, so that the lower end of the movable rod is located in the slide groove 29. When the movable plate 4 moves horizontally relative to the fixed plate 2, the lower end of the movable rod slides in the slide groove 29, thereby limiting the moving range of the movable plate 4 by the slide groove 29. In this embodiment, the movable rod includes a first movable rod 5 and a second movable rod 6 connected vertically.

[0032] For one set of driving components, it also includes a force-applying mechanism, which is used to apply horizontal pulling force to the movable plate 4 connected thereto, so that the movable plate 4 starts to move horizontally from the initial position. In this embodiment, the force-applying mechanism includes a pull rod 11 connected to the movable plate 4, a sliding rope 12 connected to the pull rod 11 at one end, and an operating member disposed at the other end of the sliding rope 12. Therefore, when the sliding rope 12 is pulled by the operating member and the pull rod 11 is driven, the movable plate 4 can be moved.

[0033] Furthermore, a pulley 14 capable of cooperating with the sliding rope 12 is provided in the power distribution cabinet body 1. The pulley 14 is installed in the power distribution cabinet body 1 through the pulley frame 13. When the sliding rope 12 passes over the pulley 14, its extension direction is changed from horizontal to vertical, so that the sliding rope 12 can extend to the bottom of the power distribution cabinet body 1, and the operating member is provided at the bottom of the power distribution cabinet body 1. The operating member includes a horizontal connecting plate 15 connected to the sliding rope 12, an operating plate connected to the connecting plate 15, and a group of compression springs 16 connected between the connecting plate 15 and the ground of the power distribution cabinet body 1. A limiting groove 28 for limiting the range of movement of the connecting plate 15 can also be provided on the power distribution cabinet body 1. The limiting groove 28 is provided at a position corresponding to the connecting plate 15, such as at the right bottom of the door frame 17 provided on the left side of the power distribution cabinet body 1. At this time, since the user needs to perform foot operation, the operating plate can also be called a foot pressure plate 18.

[0034] The first wedge block 7 is arranged on a side surface of the movable plate 4 close to the mounting frame 8, and the second wedge block 9 is arranged on the side of the mounting frame 8, that is, close to the side surface of the corresponding movable plate 4. The first wedge block 7 cooperates with the second wedge block 9, and the first wedge block 7 and the second wedge block 9 are correspondingly provided with a horizontal surface and an inclined surface that contacts when the mounting frame 8 moves vertically upward relative to the movable plate 4, that is, for the first wedge block 7, its upper surface is a horizontal surface, and the lower surface is an inclined surface, and for the second wedge block 9, its upper surface is an inclined surface and the lower surface is a horizontal surface. A plurality of pairs of first wedge blocks 7 and second wedge blocks 9 are arranged between the movable plate 4 and the mounting frame 8. In this embodiment, three pairs of first wedge blocks 7 and second wedge blocks 9 are respectively arranged between each group of movable plates 4 and the mounting frame 8, and are respectively distributed along the vertical direction.

[0035] The heat dissipation component can be installed on the top of the power distribution cabinet body 1 through the above-mentioned installation component, so that the fan 10 of the heat dissipation component is facing the top surface of the power distribution cabinet body 1. A heat dissipation hole connected to the outside is provided on the power distribution cabinet body 1 at a position opposite to the heat dissipation component, that is, on the top surface. A filter 21 corresponding to the area where the heat dissipation hole is located is arranged on the outside of the power distribution cabinet body 1. A fixing frame 20 is arranged on the edges of both sides of the area where the heat dissipation hole is located, so that the filter 21 is detachably mounted on the outside of the power distribution cabinet body 1 through the fixing frame 20. Through the coordinated use of the fixing frame 20 and the filter 21, it is convenient to copy and install the filter 21. The filter 21 can play a dustproof role, avoid a large amount of dirt from entering the power distribution cabinet body 1, and is conducive to extending the service life of the electrical components in the power distribution cabinet body 1. Through the setting of the heat dissipation hole, the heat in the power distribution cabinet body 1 can be dissipated in time, and the phenomenon of excessive heat inside the power distribution cabinet body 1 can be avoided, which further improves the efficiency of heat dissipation.

[0036] A shielding plate 22 is provided outside the power distribution cabinet body 1, i.e., on the top, to cover at least the area where the heat dissipation holes are located. The filter 21 and the fixing frame 20 are provided in the space between the power distribution cabinet body 1 and the shielding plate 22. It is usually adopted that the cross-sectional area of ​​the shielding plate 22 is larger than the cross-sectional area of ​​the power distribution cabinet body 1. The top of the shielding plate 22 is provided as a single-sided slope or a double-sided slope, and the inclination angle of the slope is about 10°. The shielding plate 22 can block wind and snow, and prevent rainwater from entering the power distribution cabinet body 1 and damaging the internal electrical components, thereby further extending the service life of the electrical components in the power distribution cabinet body 1.

[0037] In addition, the four corners of the bottom of the power distribution cabinet body 1 are fixedly connected with support feet 19, and the width of the support feet 19 is usually one sixth of the width of the power distribution cabinet body 1. The setting of the support feet 19 can, on the one hand, support the power distribution cabinet body 1, which is conducive to placing the power distribution cabinet body 1 more stably, and on the other hand, the bottom of the power distribution cabinet body 1 is suspended, which is conducive to heat dissipation and can improve the efficiency of heat dissipation.

[0038] The cabinet door 24 installed on one side of the power distribution cabinet body 1 has a glass 25 inlaid in its inner cavity. The glass 25 allows the user to observe the internal conditions of the power distribution cabinet body 1 and facilitates maintenance.

[0039] The disassembly and assembly process of the above heat dissipation assembly is as follows: the user opens the cabinet door 24, holds the handle 23 with his hand, and steps on the foot pressure plate 18, the foot pressure plate 18 drives the connecting plate 15 to move downward and compresses the compression spring 16, the connecting plate 15 moves downward and drives the sliding rope 12 to move downward, the sliding rope 12 drives the pull rod 11 to move to the left, the pull rod 11 drives the left movable plate 4 and the first wedge block 7 to move to the left, the left movable plate 4 compresses the left spring 3, so that the first wedge block 7 is separated from the second wedge block 9. Then move the handle 23 to the left, the handle 23 drives the mounting frame 8 to move, and the second wedge block 9 on the right side of the mounting frame 8 can be separated from the first wedge block 7 on the right side, so that the mounting frame 8 and the heat dissipation assembly are disassembled for cleaning. After disassembling the heat dissipation assembly, the left movable plate 4 can be reset. After cleaning, install the mounting frame 8. During installation, align the first wedge block 7 and the second wedge block 9 on the left and right sides, and push the mounting frame 8 upward. Under the action of the inclined surfaces of the first wedge block 7 and the second wedge block 9, the two movable plates 4 move to both sides and compress the corresponding springs 3, so that the second wedge block 9 on the mounting frame 8 passes over the first wedge block 7 until the first wedge block 7 and the second wedge block 9 correspond one by one, that is, they are installed in place. At this time, the movable plate 4 returns to its original position under the action of the spring 3, so that the first wedge block 7 supports the second wedge block 9 from below. In this state, the position of the movable plate 4 is its initial position. In this way, Czech achieves the purpose of convenient disassembly and cleaning of the internal heat dissipation components.

[0040] In summary, the power distribution cabinet has the following beneficial effects:

[0041] 1. The present invention solves the problem that the fan 10 installed in the existing distribution cabinet is not convenient for disassembly and cleaning through the coordinated use of an L-shaped fixed plate 2, a spring 3, a movable plate 4, a first movable rod 5, a second movable rod 6, a first wedge block 7, a second wedge block 9, a pull rod 11, a sliding rope 12, a pulley frame 13, a pulley 14, a connecting plate 15, a compression spring 16, a side door frame 17 of a distribution cabinet and a foot pressure plate 18. The distribution cabinet that is easy to clean has the advantage that the internal fan 10 is easy to disassemble and clean, and it is convenient for users to remove the dirt accumulated on the blades of the fan 10 in time, so that the heat dissipation efficiency of the fan 10 is greatly improved, thereby extending the service life of the electrical components inside the distribution cabinet.

[0042] 2. The present invention can support the distribution cabinet body 1 by setting the supporting feet 19, which is conducive to making the distribution cabinet more stable. The bottom is suspended in the air, which is conducive to heat dissipation and can improve the heat dissipation efficiency. The fixing frame 20 and the filter 21 are used in conjunction with each other. The fixing frame 20 can facilitate the use of the filter 21, and facilitate the removal and installation of the filter 21. The filter 21 plays a dust-proof role, avoiding the situation where a large amount of dirt enters the inner cavity of the distribution cabinet body 1, which is conducive to extending the service life of the electrical components in the inner cavity of the distribution cabinet body 1. The heat dissipation holes can be set to timely disperse the dust in the distribution cabinet body 1. The heat of the cavity is prevented, and the phenomenon of excessive heat inside the distribution cabinet body 1 is avoided, which further improves the heat dissipation efficiency. The setting of the baffle plate 22 can block rain and snow, and prevent rainwater from entering the inner cavity of the distribution cabinet body 1 and damaging the internal electrical components, further extending the service life of the electrical components in the inner cavity of the distribution cabinet body 1. The setting of the handle 23 can facilitate the disassembly of the fan 10, and avoids the phenomenon of unstable grip and falling during disassembly, which brings convenience to the user. The setting of the glass 25 can facilitate the user to observe the situation of the inner cavity of the distribution cabinet body 1, which is convenient for the user to carry out maintenance.
