Description

Technical Field

[0001] The invention relates to the field of electrical equipment, in particular to a power distribution cabinet which is easy to maintain. Background Art

[0002] The power distribution cabinet is an electrical device used to centrally distribute electrical energy. The power distribution cabinet can distribute electricity from the mains distribution cabinet to each server cabinet to ensure stable power supply for many servers. In order to ensure the safe and stable operation of the power distribution cabinet, the power distribution cabinet needs to be maintained.

[0003] The maintenance of the power distribution cabinet includes inspecting its appearance, cleaning the inside of the power distribution cabinet, testing the functions of the power distribution cabinet, etc. When cleaning the inside of an existing power distribution cabinet, operators generally use handheld brushes, hair dryers, vacuum cleaners and other tools to clean it. This cleaning method cannot remove the dust inside the power distribution cabinet in real time, causing the power distribution cabinet to accumulate dust outside of cleaning time. The dust will cover the electrical components inside the power distribution cabinet, thereby affecting the heat dissipation of the electrical components, and further reducing the service life of the electrical components.

[0004] The upper part of the existing power distribution cabinet is usually provided with ventilation holes for heat dissipation. By installing fans and other equipment at the ventilation holes, the hot air inside is forced to be sucked out to the outside of the power distribution cabinet, thereby taking away the heat generated by the electrical components in the cabinet and ensuring the service life of the electrical components. However, the existing cooling fans are usually only fixedly installed at the ventilation holes of the power distribution cabinet, which makes the air suction and heat dissipation effect poor, and dust is easily adhered and accumulated on the blades of the cooling fans, thereby reducing the air suction effect of the cooling fans, further reducing the heat dissipation effect on the electrical components.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0034] See also Figure 1 , Figure 2 and Figure 4 A power distribution cabinet which is easy to maintain comprises a cabinet body 1, a cabinet door 2 is hingedly connected to the front side of the cabinet body 1, a rear cover plate 3 is fixedly installed on the rear side of the cabinet body 1, a mounting plate 4 is fixedly installed on the inner rear part of the cabinet body 1, a suction mechanism 5 for sucking air from different positions inside the cabinet body 1 is commonly provided on the mounting plate 4, the cabinet body 1 and the rear cover plate 3, and a dust cleaning mechanism 6 for cleaning dust inside the cabinet body 1 is commonly provided on the mounting plate 4, the cabinet body 1 and the rear cover plate 3.

[0035] When the power distribution cabinet needs to be maintained, the heat emitted by the electrical components inside the cabinet 1 is absorbed and transported to the outside of the cabinet 1 through the suction mechanism 5, and the suction mechanism 5 simultaneously absorbs the dust inside the cabinet 1, so that the dust inside the cabinet 1 moves to the inside of the cleaning mechanism 6, and the dust is collected by the cleaning mechanism 6, and then the operator cleans the collected dust regularly.

[0036] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Fig. 9 The suction mechanism 5 includes a lifting plate 51 which is slidably arranged on the front side of the mounting plate 4 up and down, a movable plate 52 is slidably arranged inside the lifting plate 51 along the left and right directions, a suction head 53 is fixedly installed inside the movable plate 52, an exhaust fan 54 is fixedly installed on the rear side of the middle part of the rear cover plate 3, the exhaust fan 54 is connected with the rear side of the suction head 53 through a hose, a track groove 55 is opened on the mounting plate 4, the rear side of the suction head 53 is inserted into the track groove 55, and a moving component 56 for driving the suction head 53 to move is jointly arranged on the mounting plate 4 and the cabinet 1, and an active plate 57 is slidably arranged on the rear side of the mounting plate 4 along the vertical direction.

[0037] See also Figure 2 , Figure 4 and Figure 5 The moving component 56 includes a waist-shaped groove 561 arranged in a straight line on the active plate 57. The rear side of the suction head 53 is inserted into the waist-shaped groove 561 and cooperates with its notch. A reciprocating screw 562 is rotatably arranged on the right side of the rear side of the mounting plate 4. The reciprocating screw 562 is threadedly connected to the active plate 57. An executive motor 563 is fixedly installed on the upper part of the cabinet 1, and the output shaft of the executive motor 563 is fixedly connected to the reciprocating screw 562.

[0038] Continue reading Figure 2 , Figure 4 and Figure 5 The trajectory groove 55 is a continuous fold line structure arranged at equal intervals along the vertical direction, and the fold line structure of the trajectory groove 55 is arranged alternately to the right and to the left from top to bottom. The rear side of the suction head 53 is a circular tubular structure, and the front side of the suction head 53 is a conical structure with a diameter gradually increasing from back to front.

[0039] When the power distribution cabinet needs to be maintained, the exhaust fan 54 is started, so that the exhaust fan 54 extracts the air inside the cabinet 1 through the hose and the suction head 53 in sequence, so that the hot air inside the cabinet 1 flows to the outside of the cabinet 1 through the suction head 53, the hose, and the exhaust fan 54 in sequence, thereby dissipating the heat of the electrical components inside the cabinet 1. At the same time, the execution motor 563 is started, so that the execution motor 563 drives the reciprocating screw 562 to rotate, and the reciprocating screw 562 drives the active plate 57 to move back and forth up and down in the vertical direction.

[0040] The active plate 57 pushes the suction head 53 to move up and down synchronously, so that the suction head 53 moves along the trajectory of the trajectory groove 55, and then the suction head 53 moves back and forth left and right while moving up and down, so that the suction head 53 can move to multiple positions inside the cabinet 1, thereby increasing the suction head 53's effect of absorbing hot air inside the cabinet 1.

[0041] See also Figure 2 , Figure 3 and Figure 5 The cleaning mechanism 6 includes a filter plate 61 fixedly installed on the front side of the suction head 53, and a square tube 62 is fixedly installed on the lower side of the top wall of the cabinet 1. The rear side of the square tube 62 is flush with the front side of the filter plate 61, and an opening groove 63 is opened at the position where the square tube 62 overlaps with the track groove 55.

[0042] See also Figure 2 and Figure 3 The opening grooves 63 at the upper and lower adjacent positions are oriented in opposite directions, and the opening grooves 63 are oriented toward the height of a section of the track groove 55 at the corresponding position. A guide plate 631 corresponding to the opening grooves 63 is fixedly mounted on the square tube 62, and the guide plate 631 gradually tilts from top to bottom toward the direction close to the square tube 62, and the guide plate 631 is parallel to a section of the track groove 55 at the corresponding position.

[0043] When the suction head 53 sucks the hot air inside the cabinet 1, the suction head 53 simultaneously sucks the dust mixed in the air, so that the dust mixed in the air flows to the filter plate 61 on the front side of the suction head 53. Through the continuous flow of airflow, the dust mixed in the air accumulates on the front side of the filter plate 61, and the suction head 53 drives the filter plate 61 to move synchronously.

[0044] When the filter plate 61 moves from top to bottom to the position of the square tube 62, the filter plate 61 contacts the opening groove 63 at the corresponding position on the square tube 62, so that the square tube 62 scrapes off the dust accumulated on the filter plate 61 through the opening groove 63 thereon, and the scraped dust falls onto the guide plate 631, and then the scraped dust moves along the upper side of the guide plate 631 to the inside of the square tube 62 under the action of gravity, and then the scraped dust falls vertically along the square tube 62 to the bottom thereof, thereby collecting the dust floating in the air inside the cabinet 1.

[0045] See also Figure 2 , Figure 3 , Figure 5 and Figure 6Some dust stuck in the sieve holes of the filter plate 61 cannot be scraped off by the open groove 63 of the square tube 62 because the dust is flush with the filter plate 61. In order to clean the dust stuck in the sieve holes of the filter plate 61, the present invention designs the following structure: the cleaning mechanism 6 also includes a dust shaking assembly 66 jointly arranged on the suction head 53 and the square tube 62, and the dust shaking assembly 66 includes a sliding plate 661 that is slidably arranged on the suction head 53, and a hammer column 662 is fixedly installed at the lower part of the sliding plate 661, and the hammer column 662 is located at a coaxial position inside the suction head 53. An active spring is arranged between the rear side of the sliding plate 661 and the suction head 53, and the upper part of the sliding plate 661 extending to the outside of the suction head 53 is provided with an inclined surface gradually inclined to the right from front to back, and the rear side of the square tube 62 is provided with pushing blocks 663 connected to it for sliding up and down sliding at equal intervals along the vertical direction.

[0046] See also Figure 3 and Figure 6 A coil spring is arranged between the support plate and the push block 663 on the rear side of the square tube 62. The push block 663 is arranged with the left side higher than the right side, and the push block 663 is parallel to a section of the track groove 55 at the corresponding position. An inclined surface is provided on the right side of the push block 663, which gradually tilts from bottom to top toward the right.

[0047] When the suction head 53 drives the filter plate 61 to move from the upper left to the lower right to the position of the square tube 62, the suction head 53 drives the sliding plate 661 to move to contact with the pushing block 663 at the corresponding position, so that the left side of the pushing block 663 contacts the inclined surface on the upper part of the sliding plate 661, so that the pushing block 663 pushes the sliding plate 661 backward and compresses the active spring. When the sliding plate 661 moves to the lower right to the right side of the pushing block 663, the active spring drives the sliding plate 661 to move forward quickly under the action of its own elastic force, so that the sliding plate 661 drives the hammer column 662 to knock on the filter plate 61 from back to front, thereby shaking off the dust blocking the screen holes of the filter plate 61 and ensuring the air permeability of the filter plate 61.

[0048] When the suction head 53 moves from the lower right to the upper left, the upper part of the sliding plate 661 contacts the inclined surface on the right side of the pushing block 663, so that the sliding plate 661 pushes the pushing block 663 upward, thereby preventing the pushing block 663 from hindering the movement of the sliding plate 661.

[0049] See also Figure 2 , Figure 4 , Figure 7 and Figure 8The cleaning mechanism 6 also includes a soot blowing assembly 65 which is jointly arranged on the mounting plate 4 and the rear cover plate 3. The soot blowing assembly 65 includes a wind shield 651 fixedly mounted on the lower rear portion of the mounting plate 4. A rotating row plate 652 is rotatably arranged inside the wind shield 651. An ear seat plate 653 is fixedly mounted on the upper left portion of the wind shield 651. A pulley 654 is rotatably arranged on the upper left portion of the ear seat plate 653. A belt 655 is wound around the pulley 654 and the rotating shaft of the rotating row plate 652. The soot blowing assembly 65 also includes a power unit 656.

[0050] See also Figure 4 , Figure 7 and Figure 8 The power unit 656 includes a driven plate 6561 fixedly installed on the upper front side of the belt 655, a guide column 6562 is fixedly installed on the left side of the wind shield 651 through a support plate, the guide column 6562 is slidably connected to the driven plate 6561, an L-shaped plate 6563 is provided on the front side of the driven plate 6561 to slide along the left and right directions, a tension spring is provided between the longitudinal section of the L-shaped plate 6563 and the driven plate 6561, and a follower column 6564 is fixedly installed on the front side of the transverse section of the L-shaped plate 6563.

[0051] When the active plate 57 drives the suction head 53 to move downward to the lower part of the cabinet 1, the lower side surface of the active plate 57 abuts against the follower column 6564, so that the active plate 57 pushes the follower column 6564 downward, and the follower column 6564 drives the driven plate 6561 to move synchronously through the L-shaped plate 6563, and the driven plate 6561 drives the belt 655 to rotate, so that the belt 655 drives the rotating plate 652 to rotate slowly, and then the rotating plate 652 slowly blows the dust deposited on the bottom of the cabinet 1, so that the dust deposited on the bottom of the cabinet 1 floats slowly and in small quantities into the air of the cabinet 1, so that it is sucked and collected by the suction head 53 during the downward movement.

[0052] See also Figure 7 and Figure 8 A guide groove 6565 is provided at the rear side of the mounting plate 4 at a position corresponding to the belt 655. The upper portion of the guide groove 6565 is an L-shaped structure, and the lower portion of the guide groove 6565 is a structure gradually inclined to the left from top to bottom. The front end of the follower column 6564 is inserted into the guide groove 6565, and a return plate 6566 is fixedly installed at the lower portion of the rear side of the belt 655. A fixing plate 6567 is fixedly installed at the position corresponding to the return plate 6566 at the front side of the rear cover plate 3. The lower portion of the fixing plate 6567 is slidably connected to the return plate 6566 through an interlaced rod. A pushing spring is provided between the return plate 6566 and the fixing plate 6567. An inclined surface is provided at the upper left portion of the active plate 57.

[0053] When the follower column 6564 moves downward, it moves along the trajectory of the guide groove 6565. While the driven plate 6561 moves downward, it drives the return plate 6566 to move upward through the belt 655 and compresses the push spring. When the suction head 53 moves downward to the lower end of the trajectory groove 55, the suction head 53 is located at the lowest position inside the cabinet 1. At the same time, the follower column 6564 moves along the inclined structure at the bottom of the guide groove 6565 to the left side of the active plate 57, so that the active plate 57 no longer blocks the follower column 6564, so that the push spring pushes the return plate 6566 to move downward quickly through its own elastic force.

[0054] The return plate 6566 drives the rotating plate 652 to rotate rapidly through the belt 655, so that the rotating plate 652 can quickly blow the dust deposited at the bottom of the cabinet 1 into the air floating in the cabinet 1, so that the suction head 53 located at the lowest position inside the cabinet 1 can quickly absorb the dust, so that the suction head 53 can fully absorb the dust deposited at the bottom of the cabinet 1 to prevent the dust from falling on the electrical components.

[0055] When the push spring drives the return plate 6566 to move downward rapidly, the belt 655 drives the driven plate 6561 to move upward rapidly to the initial position, so that the driven plate 6561 drives the follower column 6564 to move to the upper end of the vertical section of the guide groove 6565L-shaped structure through the L-shaped plate 6563, and then the reciprocating screw 562 drives the suction head 53 to move upward through the active plate 57, so that the inclined surface on the upper left side of the active plate 57 contacts the follower column 6564, so that the active plate 57 pushes the follower column 6564 to the left along the horizontal section of the guide groove 6565L-shaped structure through the inclined surface thereon, so that the follower column 6564 moves to the left to the left side of the active plate 57, thereby preventing the follower column 6564 from hindering the active plate 57 from moving upward.

[0056] When the active plate 57 moves upward to the upper side of the follower column 6564, the tension spring pulls the L-shaped plate 6563 to the right through its own elastic force, so that the L-shaped plate 6563 drives the follower column 6564 to move to the right to the initial position.

[0057] See also Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 6 also includes an ash discharge component 64 jointly arranged on the cabinet 1 and the square tube 62. The ash discharge component 64 includes a cylindrical tube 641 fixedly installed on the lower part of the right side wall of the cabinet 1. The right end of the cylindrical tube 641 passes through the cabinet 1 and is connected to the outside. The left part of the cylindrical tube 641 is fixedly connected to the lower end of the square tube 62, and the left part of the cylindrical tube 641 is connected to the square tube 62. A spiral rod 642 is rotatably arranged inside the cylindrical tube 641, and a crank is fixedly installed on the right end of the spiral rod 642.

[0058] The dust that falls to the bottom of the square tube 62 flows to the left side of the inside of the cylindrical tube 641. Then the operator manually turns the crank regularly, and the crank drives the spiral rod 642 to rotate synchronously, so that the spiral rod 642 pushes the dust on the left side of the inside of the cylindrical tube 641 to the right to the outside of the cabinet 1, thereby collecting and discharging the dust.

[0059] When maintaining the power distribution cabinet, the present invention also includes the following steps: the first step is to start the exhaust fan 54 to extract the hot air inside the cabinet 1 through the suction head 53, and at the same time start the execution motor 563 to drive the suction head 53 to move to multiple positions inside the cabinet 1 through the reciprocating screw 562, thereby increasing the suction effect of the suction head 53 on the hot air inside the cabinet 1.

[0060] In the second step, the suction head 53 absorbs the dust mixed in the air onto the filter plate 61, and then the suction head 53 drives the filter plate 61 to move from top to bottom to the position of the square tube 62, so that the opening groove 63 scrapes off the dust accumulated on the filter plate 61, and the scraped dust moves along the guide plate 631 to the inside of the square tube 62, and then the scraped dust falls vertically along the square tube 62 to the bottom thereof, thereby collecting the dust floating in the air inside the cabinet 1.

[0061] In the third step, the air suction head 53 drives the sliding plate 661 to move to contact with the pushing block 663 at the corresponding position, so that the pushing block 663 pushes the sliding plate 661 backward and compresses the active spring. When the sliding plate 661 moves to the lower right to the right side of the pushing block 663, the active spring drives the hammer column 662 to knock on the filter plate 61 from back to front, thereby shaking off the dust blocking the screen holes of the filter plate 61 to ensure the air permeability of the filter plate 61.

[0062] In the fourth step, the suction head 53 moves downward to the lower part of the cabinet 1, and the active plate 57 drives the rotating row plate 652 to rotate slowly by pushing the follower column 6564 downward, so that the rotating row plate 652 slowly and in small amounts blows the dust deposited on the bottom of the cabinet 1 into the air floating in the cabinet 1, thereby being sucked and collected by the suction head 53 during the downward movement.

[0063] In the fifth step, the suction head 53 moves downward to the lowest position inside the cabinet 1, and the follower column 6564 moves to the left side of the active plate 57 along the inclined structure at the bottom of the guide groove 6565, so that the active plate 57 no longer blocks the follower column 6564, and the push spring drives the rotating plate 652 to rotate rapidly by quickly pushing the return plate 6566 downward, so that the suction head 53 located at the lowest position inside the cabinet 1 can quickly absorb the dust, so that the suction head 53 can fully absorb the dust deposited at the bottom of the cabinet 1 to prevent dust from falling on the electrical components.

[0064] In the sixth step, the operator manually turns the crank periodically, and the crank drives the spiral rod 642 to rotate synchronously, so that the spiral rod 642 pushes the dust on the left side of the cylindrical tube 641 to the right to the outside of the cabinet 1, thereby collecting and discharging the dust.

[0065] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
