Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, in particular to a high and low voltage power distribution cabinet heat dissipation structure and the power distribution cabinet. Background Art

[0002] Distribution cabinets, which include power distribution cabinets, lighting distribution cabinets, and metering cabinets, are the final stage of the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in applications with dispersed loads and a small number of circuits, while motor control centers are used in applications with concentrated loads and a large number of circuits. They distribute power from a circuit in the upper-level distribution equipment to nearby loads.

[0003] In order to solve the internal heat dissipation problem, most existing distribution cabinets have several long heat dissipation holes on the box body to achieve better heat dissipation effect. If the above method is adopted, it is impossible to prevent mosquitoes from entering the box body, which is easy to cause certain damage to internal components. Although a filter net is currently added to prevent mosquitoes from easily entering the box body through the heat dissipation holes, the filter net will accumulate dust after being used for a period of time, which is easy to have a certain impact on heat dissipation. Therefore, the filter net needs to be cleaned. However, most existing filters are fixed in the box body, which is inconvenient to clean.

[0004] In view of this, the inventor specially designed a high and low voltage distribution cabinet heat dissipation structure and distribution cabinet, which resulted in this case. Summary of the Invention

[0005] In order to solve the above problems, the technical solutions of the present invention are as follows:

[0006] One of the purposes of the present invention is to provide a heat dissipation structure for a high and low voltage distribution cabinet, comprising a heat dissipation box, a closing device disposed in the heat dissipation box and slidable along the inner wall of the heat dissipation box, and a filtering device disposed in the heat dissipation box and detachably connected thereto;

[0007] A first heat dissipation hole communicating with the interior of the heat dissipation box is provided on one side thereof, and a second heat dissipation hole communicating with the interior thereof is provided on the other side thereof. A first through hole for a filter device to enter the interior thereof is further provided on the upper end of the heat dissipation box, and a cleaning device is provided in the heat dissipation box and near the first through hole.

[0008] The filtering device is installed inside the heat dissipation box, and the closing device moves downward, so that the first heat dissipation hole and the second heat dissipation hole are connected to the inside of the heat dissipation box; the filtering device is taken out, and the closing device moves upward, so that the first heat dissipation hole and the second heat dissipation hole are not connected to the inside of the heat dissipation box.

[0009] Furthermore, the heat dissipation box includes a lower box with an opening and a cover arranged at the opening. The first heat dissipation hole and the second heat dissipation hole are arranged in the lower box, and the first through hole is arranged on the cover.

[0010] Furthermore, two installation steps extending into the lower box body and used for installing a cleaning device are provided below the cover body, one side of the installation step abuts against the inner wall of the lower box body, and the cleaning device is detachably connected to the installation step.

[0011] Furthermore, the cleaning device includes a brush that is detachably connected to the inner walls of the two mounting steps and is used to remove dust; the inner walls of the mounting steps are provided with a convex slide, the bottom of the brush is slidably connected to the slide, and the front end faces the filtering device.

[0012] Furthermore, the closing device includes a positioning column arranged at the bottom of the heat dissipation box, a base plate slidably connected to the bottom and the positioning column, a first closing plate and a second closing plate arranged on the base plate, and a spring arranged between the base plate and the bottom of the heat dissipation box and sleeved on the positioning column. The first closing plate is arranged to connect the first heat dissipation hole and the first connecting hole inside the heat dissipation box, and the second closing plate is arranged to connect the second heat dissipation hole and the second connecting hole inside the heat dissipation box.

[0013] Furthermore, a limiting step is provided at the bottom of the heat dissipation box and below the closing device.

[0014] Furthermore, the filtering device includes a frame for support and a filter net with mesh holes embedded in the frame.

[0015] Furthermore, the inner wall of the lower box body is also provided with a limit groove for limiting the position of the frame, and two handles are also provided on the outer side of the lower box body; and an avoidance groove for taking out the filter device is also provided above the cover body.

[0016] Furthermore, a magnet for adsorption is also provided on the outer side wall of the heat dissipation box.

[0017] Furthermore, the first heat dissipation hole and the second heat dissipation hole have the same aperture, are both tilted, and have openings tilted downward. The first connection hole and the second connection hole have the same aperture, and are larger or slightly larger than the first heat dissipation hole. They are also tilted, and their openings are in the same direction as the first heat dissipation hole.

[0018] Furthermore, when heat dissipation is achieved, the central axis of the first heat dissipation hole coincides with the central axis of the first connecting hole. When cleaning is required, the first closing plate and the second closing plate move upward under the action of the spring, and the first heat dissipation hole and the first connecting hole are staggered, and the second heat dissipation hole and the second connecting hole are staggered, so as to prevent dust from being emitted from the first heat dissipation hole and the second heat dissipation hole.

[0019] The second object of the present invention is to provide a distribution cabinet, which adopts the heat dissipation structure described in the first object, and also includes an outer shell. The heat dissipation structure can be detachably installed below the outer wall of the outer shell. An installation groove is provided on the outer wall of the outer shell, and a second through hole connected to the inner side of the outer shell is provided at the bottom of the installation groove.

[0020] The heat dissipation structure of the present invention can prevent mosquitoes from entering and causing short circuits while dissipating heat by arranging a filtering device inside the heat dissipation box. In addition, the filtering device can prevent dust from entering. During normal use, the filtering device is located in the heat dissipation box. Under the action of gravity, the closing device moves downward, so that the first heat dissipation hole and the second heat dissipation hole are connected to the inside of the heat dissipation box. After a period of use, the filtering device is cleaned by a cleaning device, and the filtering device is taken out of the heat dissipation box. The closing device moves upward, blocking the connection between the heat dissipation box and the outside, effectively preventing dust from flying, and playing a certain protective role for the operator. Therefore, the heat dissipation structure of the present invention can not only achieve rapid cleaning, but also prevent dust from flying. BRIEF DESCRIPTION OF THE DRAWINGS

The filter device 30 can prevent mosquitoes from entering and causing short circuits in components, and can also prevent dust from entering and affecting the service life of components. The filter device 30 is detachable, and the filter device 30 can be regularly cleaned, maintained, or replaced. Specifically, the filter device 30 is slidably connected to the inside of the heat dissipation box body 10.

[0036] A first heat dissipation hole 111 is provided on one side of the heat dissipation housing 10, communicating with its interior, and a second heat dissipation hole 112 is provided on the other side of the heat dissipation housing 10. A first through-hole 121 is also provided at the upper end of the heat dissipation housing 10, through which the filter device 30 enters. A cleaning device 40 is provided within the heat dissipation housing 10, positioned near the first through-hole 121. When the filter device 30 is withdrawn upward, the cleaning device 40 cleans the filter device 30, resulting in simple operation and high cleaning efficiency. The heat dissipation housing 10 of this embodiment includes a lower housing 11 having an opening, and a cover 12 disposed at the opening. The first heat dissipation hole 111 and the second heat dissipation hole 112 are disposed in the lower housing 11, and the first through-hole 121 is disposed in the cover 12. The number of the first heat dissipation hole 111 and the second heat dissipation hole 112 can be set as needed.

[0037] The filter device 30 is installed inside the heat dissipation box 10, the closing device 20 moves downward, and the first heat dissipation hole 111 and the second heat dissipation hole 112 are both connected to the interior of the heat dissipation box 10; the filter device 30 is taken out, the closing device 20 moves upward, and the first heat dissipation hole 111 and the second heat dissipation hole 112 are not connected to the interior of the heat dissipation box 10.

[0038] Two mounting steps 122 extending into the lower box body 11 and used to install the cleaning device 40 are provided under the cover body 12. The two sides of the two mounting steps 122 are against the inner wall of the lower box body 11, and the cleaning device 40 is detachably connected to the mounting steps 122, specifically by a sliding connection method; the cleaning device 40 includes two brushes 41 that are detachably connected to the inner walls of the two mounting steps 122 and used to remove dust; a convex-shaped slide 123 is provided on the inner wall of the mounting step 122, the bottom of the brush 41 is slidably connected to the slide 123, and the front end faces the filter device 30, that is, the end with bristles faces the filter device 30, and ensures that when the filter device 30 slides upward, the brush 41 can contact both sides of the filter device 30 for cleaning.

[0039] The closing device 20 includes a positioning column 21 arranged at the bottom of the heat dissipation box 10, a bottom plate 22 slidably connected to the positioning column 21, a first closing plate 23 and a second closing plate 24 arranged on the bottom plate 22, and a spring 25 arranged between the bottom plate 22 and the bottom of the heat dissipation box 10 and sleeved on the positioning column 21.

When the filter device 30 is placed in the heat dissipation box 10, under the action of gravity, the bottom plate 22 presses the spring 25 downward and is positioned by the limiting step 113 to ensure that during heat dissipation work, the first connection hole 231 coincides with the center axis of the first heat dissipation hole 111, and the second connection hole 241 coincides with the center axis of the second heat dissipation hole 112.

[0040] The filter device 30 includes a frame 31 for support, and a filter screen 32 embedded within the frame 31 and having a mesh (not shown; a conventional filter screen 32 will suffice).

They are also tilted, and their openings face the same direction as the first heat dissipation hole 111. When heat dissipation is achieved, the central axes of the first heat dissipation hole 111 and the first connection hole 231 coincide. When dust cleaning is required, the first and second closing plates 23 and 24 are moved upward by the spring 25, staggering the first and second heat dissipation holes 111 and 231, and the second heat dissipation holes 112 and 241, to prevent dust from escaping through the first and second heat dissipation holes 111 and 112.

After a period of use, the filtering device is cleaned by a cleaning device, and the filtering device is taken out of the heat dissipation box. The closing device moves upward, blocking the connection between the heat dissipation box and the outside, effectively preventing dust from flying, and playing a certain protective role for the operator. Therefore, the heat dissipation structure of the present invention can not only achieve rapid cleaning, but also prevent dust from flying.
