Description

Technical Field

[0001] The present invention relates to the technical field of ring network cabinets, and in particular to a ring network cabinet. Background Art

[0002] In the power supply network system, in order to improve the reliability of power supply, the power supply network is usually connected into a ring so that users can obtain power from two directions. This power supply method is referred to as ring network power supply. The ring network cabinet in the ring network power supply equipment is the core switch equipment. When the ring network cabinet is in operation, a large amount of heat will be generated. If the internal space cannot be cooled in time, the internal components will work in a continuous high temperature environment and are easily damaged, shortening the service life of the components. Therefore, heat dissipation treatment is required.

[0003] The patent document with authorization announcement number CN114784683B discloses a ring network cabinet heat dissipation device, including a frame, a rotating hole is arranged on the side of the frame, a rotating shaft is arranged in the rotating hole, and the end of the rotating shaft outside the rotating hole is connected to a driving assembly, a moving part is arranged in the frame, the moving part is provided with a first through hole, and the rotating shaft passes through the first through hole; a connecting unit is fixedly connected to the moving part; the heat dissipation unit includes a heat dissipation frame fixedly connected to the connecting unit, and a heat dissipation fan is arranged in the heat dissipation frame; when the heat dissipation device is running, the heat dissipation unit can be driven by the driving assembly to reciprocate in the frame to dissipate heat at different positions in the ring network cabinet, and the heat dissipation fan can quickly discharge the hot air generated by the electronic devices inside the ring network cabinet body to prevent the electronic devices from short-circuiting due to excessive temperature inside the ring network cabinet body.

[0004] When the above-mentioned ring network cabinet dissipates heat through the cooling fan, although a dustproof net is provided at the heat dissipation port, dust may pass through the dustproof net and enter the interior of the cabinet. At the same time, when the ring network cabinet is opening and closing the cabinet door, some dust will directly enter the cabinet and gradually accumulate on the surface of the electronic components, resulting in a decrease in the heat dissipation efficiency of the electronic components themselves, affecting the heat dissipation effect of the electronic components, and thus affecting the normal operation of the ring network cabinet.

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 9 As shown, a ring main unit of the present invention comprises a cabinet body 1 and a cabinet door 11 hinged to the front end of the cabinet body 1 , and also comprises a heat dissipation mechanism and a dust cleaning mechanism arranged in the cabinet body 1 .

[0041] The right end of the cabinet door 11 is hinged to the cabinet body 1, and dustproof parts 12 are connected between the upper and lower ends of the cabinet door 11 and the cabinet body 1. The dustproof parts 12 can be expanded or contracted as the cabinet door 11 is opened or closed, so that when the cabinet door 11 is opened, the dustproof parts 12 can cover the upper and lower sides of the cabinet door 11.

[0042] Specifically, Figures 1 to 3 As shown, by providing the dustproof part 12, the upper and lower sides of the cabinet door 11 are shielded during the process of opening the cabinet door 11, thereby reducing the possibility of dust and other pollutants entering the cabinet body 1 when the cabinet door 11 is opened, and improving the sealing performance of the cabinet body 1.

[0043] The heat dissipation mechanism includes multiple groups of heat dissipation components and a driving structure 1. The multiple groups of heat dissipation components are arranged in an array along the height direction of the cabinet 1. Each group of heat dissipation components includes two heat dissipation fans 2. Multiple air inlets 13 are provided on the right side of the cabinet 1, and multiple air outlets 14 are provided on the left side of the cabinet 1. Filters 15 are provided at the air inlets 13 and the air outlets 14. The two heat dissipation fans 2 are respectively arranged on the left and right sides of the cabinet 1, and the air outlet ends are both facing the left side to form an airflow from right to left in the cabinet 1. The driving structure 1 is used to drive the heat dissipation fan 2 to rotate when the cabinet door 11 is opened, so that the air outlet end of the heat dissipation fan 2 faces the opening side of the cabinet door 11.

[0044] Specifically, Figures 1 to 3 As shown, when the cabinet door 11 is closed, the air outlet ends of the two cooling fans 2 are both facing the left side. As the equipment in the cabinet 1 generates heat during operation, the air temperature in the cabinet 1 will increase. At this time, the cooling fan 2 is started, and the cooling fan 2 located on the right side will inhale cold air into the cabinet 1 through the air inlet 13. The cold air and the hot air exchange heat in the cabinet 1. After the heat exchange, the heated air is discharged from the air outlet 14 by the cooling fan 2, forming an airflow from right to left, taking away the heat in the cabinet 1. The cooling fan 2 continuously inhales cold air and discharges hot air, so that the equipment in the cabinet 1 can be maintained to operate within a safe temperature range; when the cabinet door 11 is opened, the two cooling fans 2 can be driven to rotate under the action of the driving structure 1, so that the air outlet ends of the two cooling fans 2 are both facing the opening side of the cabinet door 11. At this time, as the blades in the cooling fan 2 rotate, an airflow blowing toward the opening side of the cabinet door 11 will be formed, thereby further reducing the possibility of dust and other pollutants entering the cabinet 1 from the opening side of the cabinet door 11 under the influence of the airflow.

[0045] The cleaning mechanism includes an air blowing component and an air suction component. The air blowing component includes a plurality of air bags 3 and a driving structure 2 arranged on the cabinet door 11. Each air bag 3 is provided with a plurality of jet holes 301 along its height direction. The driving structure 2 is used to open the plurality of jet holes 301 in sequence from bottom to top. The air suction component includes a movable frame 4 communicated with the air bag 3 and a driving structure 3. The movable frame 4 is provided with a plurality of suction holes 401. The driving structure 3 is used to drive the movable frame 4 to move and squeeze the plurality of air bags 3 in sequence from right to left so that the gas in the air bag 3 is ejected from the jet holes 301.

[0046] Specifically, Figures 2 to 6As shown, the moving frame 4 is driven to move by the driving structure 3. During this process, the multiple airbags 3 can be squeezed from right to left in sequence. When a certain airbag 3 is squeezed, the multiple jet holes 301 on the airbag 3 can be opened in sequence from bottom to top under the action of the driving structure 2, so that the gas in the airbag 3 is ejected outward from the jet holes 301 to blow off the dust attached to the cabinet 1. By opening the multiple jet holes 301 in sequence from bottom to top, the blown dust can be gradually blown to the top of the cabinet 1, so that most of the dust can be blown away by the airflow blown out by the cooling fan 2. At the same time, by squeezing multiple air bags 3 from right to left in sequence, the interior of the cabinet 1 can be cleaned step by step from right to left, so that the blown dust is gradually discharged from the air outlet 14. When the air bags 3 are released from squeezing, they will expand under the action of their own elasticity. At this time, the gas in the cabinet 1 will enter the mobile frame 4 through the air suction hole 401 provided on the mobile frame 4, and then enter the interior of the air bags 3. In this process, a small part of the dust remaining in the cabinet 1 will be sucked into the mobile frame 4 with this part of the airflow for collection, thereby further ensuring the normal operation of the distribution cabinet.

[0047] In some embodiments, a hollow through rod 31 is connected to the side of the cabinet door 11 facing the cabinet body 1, and multiple air bags 3 are respectively connected to the interior of the through rod 31, and a one-way valve is provided between each air bag 3 and the through rod 31, so that the gas can only flow from the through rod 31 to the interior of the air bag 3, but cannot flow back from the air bag 3 to the interior of the through rod 31. A connecting pipe 32 is connected between the through rod 31 and the movable frame 4, and the two ends of the connecting pipe 32 are respectively fixedly connected to the through rod 31 and the movable frame 4, and the length of the connecting pipe 32 can be adapted as the movable frame 4 moves.

[0048] Specifically, Figures 2 to 7 As shown, a one-way valve is provided so that when the airbag 3 is squeezed, the gas inside the airbag 3 cannot enter the through rod 31 through the one-way valve, and can only be ejected outward from the jet hole 301 to blow away the dust attached to the equipment in the cabinet, and the detached dust will be discharged from the air outlet 14 along with the air flow blown out by the cooling fan 2; after the airbag 3 is free from squeezing, it will expand under the action of its own elasticity. During this process, the gas in the cabinet 1 will enter the movable frame 4 through the suction hole 401 provided on the movable frame 4, and enter the through rod 31 through the connecting pipe 32, and then enter the corresponding airbag 3 through the one-way valve, so that the airbag 3 gradually returns to its original state.

[0049] In some embodiments, an extrusion frame 41 is provided between the airbag 3 and the movable frame 4 , the extrusion frame 41 is fixedly connected to the movable frame 4 , a curved surface for extruding the airbag 3 is provided on the side of the extrusion frame 41 facing the airbag 3 , and the second driving structure is provided on the extrusion frame 41 .

[0050] Specifically, Figures 2 to 7As shown, while the moving frame 4 is driven to move by the driving structure three, the extrusion frame 41 connected thereto will be driven to move. When the extrusion frame 41 moves from right to left, the arc surface on the extrusion frame 41 will contact with multiple air bags 3 in turn, and squeeze the air bags 3, so that the gas in the air bags 3 is ejected from the jet holes 301, and the dust attached to the equipment in the cabinet is blown off, so that the detached dust is discharged from the air outlet 14 together with the airflow blown out by the cooling fan 2. By squeezing the multiple air bags 3 in turn from right to left, the interior of the cabinet 1 can be gradually cleaned from right to left, thereby ensuring the cleaning effect.

[0051] In some embodiments, each jet hole 301 is provided with a baffle 33, a rotating plate 34 and an air blowing pipe 35. The baffle 33 and the rotating plate 34 are both arc-shaped. The baffle 33 is fixedly connected to the airbag 3. The rotating plate 34 slides with the baffle 33 along the circumference of the baffle 33, and a torsion spring is provided between the baffle 33 and the baffle 33. A through hole 331 is provided on the baffle 33. The air blowing pipe 35 is provided on the side of the rotating plate 34 away from the baffle 33, and the end portion passes through the rotating plate 34 and communicates with the inside of the airbag 3. The driving structure 2 can drive the air blowing pipe 35 to flip upward to open the jet hole 301.

[0052] Specifically, Figures 3 to 9 As shown, in the initial state, the blowing pipe 35 is in a horizontal state. At this time, the baffle 33 can close the end of the blowing pipe 35, so that the blowing pipe 35 is not connected to the inside of the airbag 3, that is, the jet hole 301 is in a closed state. When the blowing pipe 35 is driven to flip upward by the driving structure 2, the rotating plate 34 will be driven to rotate, and the torsion spring will be twisted to store force. As the blowing pipe 35 rotates, the end of the blowing pipe 35 will gradually point to the opening 331 on the baffle 33. At this time, the blowing pipe 35 is connected to the inside of the airbag 3, that is, the jet hole 301 is in an open state, so that when the airbag 3 is squeezed, the gas inside the airbag 3 can pass through the baffle The passage 331 on 33 enters into the interior of the air blowing pipe 35 and is sprayed out from the other end of the air blowing pipe 35 to clean the interior of the cabinet 1. When the driving structure 2 releases the force on the air blowing pipe 35, the rotating plate 34 is reset under the action of the torsion spring, and drives the air blowing pipe 35 to return to a horizontal state, so that the jet hole 301 is closed. It can be understood that when the jet hole 301 is in an open state, the gas in the airbag 3 can be sprayed outward through the inclined air blowing pipe 35, forming an inclined upward airflow, so as to blow the dust in the cabinet 1 upward, which is conducive to the dust being discharged outward with the airflow blown out by the cooling fan 2, and further improving the cleaning effect.

[0053] In some embodiments, the driving structure 1 is provided in two groups, which are used to drive the cooling fans 2 on the left and right sides of the cabinet 1 to rotate respectively. Each group of the driving structure 1 includes a rack 21, a gear 22 and a rotating shaft 23. The multiple cooling fans 2 on the same side are mounted on the rotating shaft 23 on the corresponding side. A mounting frame 24 is fixed in the cabinet 1. The rack 21 is arranged on the mounting frame 24. The rack 21 and the mounting frame 24 are relatively fixed in the height direction and slidably matched in the horizontal direction. The gear 22 is rotatably arranged on the mounting frame 24 and sleeved on the rotating shaft. On the outer side of 23, the gear 22 is meshed and connected with the rack 21. In the present embodiment, the rack 21 in the driving structure 1 located on the opening side of the cabinet door 11 is arc-shaped, and the end of the rack 21 facing the cabinet door 11 is connected to the cabinet door 11, and slides along its own arc direction when the cabinet door 11 is opened. The rack 21 in the driving structure 1 located on the hinged side of the cabinet door 11 is straight-line-shaped, and the end of the rack 21 facing the cabinet door 11 is hinged to the cabinet door 11 through the connecting rod 25, and slides along the front-rear direction when the cabinet door 11 is opened.

[0054] Specifically, Figures 1 to 4 As shown, when the cabinet door 11 is opened, the connection between the cabinet door 11 and the rack 21 can drive the arc-shaped rack 21 to slide along its own arc direction, and drive the linear rack 21 to slide toward the front side of the cabinet body 1. At this time, the meshing transmission between the rack 21 and the gear 22 can drive the gear 22 to rotate, and drive the rotating shaft 23 connected to the gear 22 to rotate, and at the same time drive the cooling fan 2 connected to the rotating shaft 23 to rotate, so that the air outlet end of the cooling fan 2 is toward the cabinet door 1. 1, forming an airflow blowing toward the open side of the cabinet door 11, preventing dust from entering the interior of the cabinet 1 from the open side of the cabinet door 11; when closing the cabinet door 11, the arc-shaped rack 21 will be driven to slide in the reverse direction along its own arc direction, and the straight rack 21 will be driven to slide toward the rear side of the cabinet 1. At this time, with the cooperation of the rack 21 and the gear 22, the cooling fan 2 will be driven to rotate in the reverse direction, so that the air outlet end of the cooling fan 2 is facing the left side of the cabinet 1 again, and the interior of the cabinet 1 continues to dissipate heat.

[0055] In some embodiments, driving structure 2 includes a plurality of push rods 36 disposed on an extrusion frame 41, wherein the plurality of push rods 36 are arranged along the height direction of the cabinet 1, and each push rod 36 is arranged along the left-right direction. A slope is provided at one end of each push rod 36 facing the left side, and the slope gradually inclines from top to bottom toward the left side of the cabinet 1, and the lengths of the plurality of push rods 36 decrease from bottom to top, so that when the extrusion frame 41 moves from right to left, the plurality of push rods 36 can contact the corresponding blowing pipes 35 in sequence from bottom to top.

[0056] Specifically, Figures 3 to 8As shown, while the driving structure 3 drives the moving frame 4 and the extrusion frame 41 to move, it will drive the multiple push rods 36 arranged on the extrusion frame 41 to move. In the process of the push rod 36 moving from right to left, the inclined surface on the push rod 36 will contact the blowing pipe 35 in a horizontal state, and under the action of the inclined surface, the blowing pipe 35 is pushed to flip upward, so that the air jet hole 301 is opened, and the dust attached to the equipment in the cabinet is blown off. Since the lengths of the multiple push rods 36 decrease from bottom to top, in the process of the extrusion frame 41 moving from right to left, the multiple push rods 36 can contact the corresponding blowing pipe 35 in sequence from bottom to top, so that the multiple air jet holes 301 on the airbag 3 can be opened in sequence from bottom to top, and the blown dust is gradually blown upward, so that the dust is discharged outward with the airflow blown out by the cooling fan 2.

[0057] In some embodiments, the driving structure three includes a screw 42 and a motor 43. The screw 42 is arranged on the cabinet door 11 to rotate along the left and right directions. The motor 43 is installed on the cabinet door 11, and the output end is connected to the screw 42. The movable frame 4 is threadedly matched with the screw 42.

[0058] Specifically, Figures 3 to 7 As shown, when the starting motor 43 drives the screw 42 to rotate, the threaded cooperation between the screw 42 and the moving frame 4 can drive the moving frame 4 to move along the axial direction of the screw 42, and drive the extrusion frame 41 connected to the moving frame 4 to move, so that the moving frame 4 and the extrusion frame 41 can reciprocate in the cabinet 1 along the left and right directions. During the movement of the extrusion frame 41, multiple air bags 3 can be squeezed in turn, so that the gas in the air bags 3 is ejected from the jet holes 301, and the dust attached to the equipment in the cabinet is blown off. At this time, most of the dust blown off can be discharged outward with the airflow blown out by the cooling fan 2. During the movement of the moving frame 4, a small part of the remaining dust can be adsorbed through the multiple suction holes 401 provided on the moving frame 4, and this part of the dust is collected in the moving frame 4 for subsequent processing.

[0059] In some embodiments, the cleaning mechanism also includes a cleaning component, which includes a dust bag 5 arranged on the cabinet door 11, and a moving rod 51 connected to the dust bag 5. A connecting pipe 2 is connected between the dust bag 5 and the moving frame 4. The two ends of the connecting pipe 2 are respectively fixedly connected to the dust bag 5 and the moving frame 4, and the length of the connecting pipe 2 can be adapted with the movement of the moving frame 4. A cleaning port 111 communicating with the interior of the dust bag 5 is provided on the cabinet door 11. During the movement of the extrusion frame 41, the moving rod 51 can be pushed to move in a direction away from the dust bag 5.

[0060] Specifically, Figures 2 to 7As shown, when the extrusion frame 41 moves to the left side of the cabinet 1 and contacts the moving rod 51, as the extrusion frame 41 continues to move, it will push the moving rod 51 to move away from the dust collecting bag 5, so that the volume of the dust collecting bag 5 becomes larger and the internal space increases, resulting in a decrease in the pressure inside the dust collecting bag 5, thereby forming a pressure difference between the inside of the dust collecting bag 5 and the inside of the cabinet 1. At this time, the gas in the cabinet 1 will enter the moving frame 4 through the suction hole 401, and then enter the dust collecting bag 5 through the connecting pipe 2. In this process, the dust adsorbed in the moving frame 4 will enter the dust collecting bag 5 together with the airflow, and then the dust in the dust collecting bag 5 can be cleaned through the cleaning port 111.

[0061] 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 of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
