Description

Technical Field

[0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to an outdoor rainproof power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet and lighting distribution cabinet, which is the final equipment of the distribution system and the general name of the motor control center. For example, CN111864603B discloses an electric power distribution cabinet with high efficiency heat dissipation, including a distribution box, a heat dissipation cabinet is fixedly arranged in the middle of the distribution box, an electric power installation board is arranged on the outside of the heat dissipation cabinet, heat dissipation windows are fixedly arranged on the surfaces of both sides of the heat dissipation cabinet, a mounting bracket rod is arranged inside the heat dissipation window, and the two ends of the mounting bracket rod are respectively fixedly connected to two electric power installation boards, and heat dissipation leaves are fixedly arranged on the surface of the mounting bracket rod. The present invention evaporates heat through the heat dissipation leaves, guides the airflow with the induced draft blades, and allows the airflow to enter the heat dissipation cabinet, thereby improving the air flow inside the heat dissipation cabinet and improving the heat dissipation effect of the heat dissipation leaves; however, for the distribution cabinet used outdoors, when it rains and there is wind in the environment, rainwater will be blown into the inside of the distribution box under the action of wind, thereby affecting the normal use of the electrical components in the distribution box.

[0003] For another example, CN110994391A discloses a power distribution cabinet that is convenient for heat dissipation, dust and rainproof, which includes a cabinet; an isolation box is symmetrically fixedly installed on the inner wall of the cabinet; an adjustment component is movably connected inside the isolation box; a cylinder is movably connected to a side surface relative to the outer side of the upper end of the cabinet; a heat dissipation hole A is arrayed on a side surface relative to the outer side of the cabinet; a dustproof net is fixedly installed on the outer side of the heat dissipation hole A; a pair of slopes arranged opposite to each other are arranged on the top of the cabinet; the bottom of the slope extends into the cylinder; a collar is fixedly installed on a side surface relative to the outer side of the upper end of the cabinet; a block is fixedly installed under the collar; and a fixed ring is fixedly installed on the side surface of the cylinder. The heat dissipation hole is closed in time in heavy rain to prevent rainwater from entering the power distribution cabinet. Although it realizes the rainproof function, the heat hole is closed when it rains, and the power distribution cabinet cannot dissipate heat through the heat dissipation hole at this time.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0044] See also Figure 1-2 As shown in , 8 and 10-11, the present invention is an outdoor rainproof distribution cabinet, which is placed outdoors when in use, and includes a base 2 supported and installed on the ground, four rectangularly distributed columns 20 are fixed on the upper surface of the base 2, the tops of the four columns 20 are connected to the top cover 23, and an annular water retaining edge 22 is arranged on the upper surface of the base 2 inside the four columns 20, and the adjacent two side walls of the columns 20 are respectively provided with mounting grooves 21 for mounting the columns 20, and the inner side walls of the mounting grooves 21 are provided with a rubber sealing layer. When in use; a side panel 1 is fixed between two adjacent columns 20 by screws, rivets or other equivalent fixing methods, and a rectangular ventilation hole 10 is opened at the bottom of the side panel 1. The setting of the ventilation hole 10 facilitates ventilation and heat dissipation during daily use.

[0045] In order to prevent rainwater from entering the interior of the power distribution cabinet through the ventilation holes 10 under the action of wind when it rains, the present invention arranges a pair of symmetrically arranged L-shaped plates 12 on the outer wall of the side panel 1 located at the ventilation holes 10, and at the same time, a rain shield 13 sliding along the channel formed by the two L-shaped plates 12 is arranged on the outer wall of the side panel 1. Then, when it rains during use, the rain shield 13 is controlled to fall down to cover the ventilation holes 10, so as to prevent rainwater from entering the interior of the power distribution cabinet through the ventilation holes 10 under the action of wind.

[0046] Similarly, when it rains, when rainwater hits the outer wall of the side panel 1, it will flow downward along the outer wall of the side panel 1. When passing through the ventilation hole 10, it is easy to enter the inside of the power distribution cabinet through the ventilation hole 10. Furthermore, the present invention also provides an inverted U-shaped water retaining strip A101 on the outer wall of the side panel 1 located at the ventilation hole 10, and the inner wall of the rain shield 13 is provided with a U-shaped water retaining strip B131 that cooperates with the U-shaped water retaining strip A101. Then, when in use, the setting of the U-shaped water retaining strip B131 is utilized to prevent rainwater from hitting the rain shield 13 and sliding down along the inner wall of the rain shield 13 and entering the inside of the power distribution cabinet; at the same time, the setting of the U-shaped water retaining strip A101 is utilized to prevent rainwater from hitting the outer wall of the side panel 1 and sliding downward along the outer wall of the side panel 1 and entering the inside of the power distribution cabinet.

[0047] It is known that if Figure 3 As shown, in order to keep the rain shield 13 able to control its up and down movement along the axial direction of the channel, a traction rope A130 is connected to the top of the rain shield 13, and the traction rope A130 passes through the through hole A set on the top of the side panel 1; and a rotating disk A3a for controlling the movement of the traction rope A130 is set on the inner top side surface of the top cover 23; and a stop boss A11 is set below the ventilation hole 10, that is, when the rain shield 13 is controlled to fall and block the ventilation hole 10, the bottom end of the rain shield 13 abuts against the upper surface of the stop boss A11.

[0048] It should be noted that in order to prevent the rain shield 13 from getting stuck at any position in the channel during the up and down movement, and to keep the rain shield 13 close to the outer wall of the side panel 1 after the rain shield 13 falls; Figure 9-15 When the present invention is used, when the bottom end of the rain shield 13 is against the upper surface of the stop boss A11, an external force is applied to the rain shield 13, thereby causing the rain shield 13 to be closely attached to the outer wall of the side plate 1; that is, on the basis of the above, if Fig.16As shown, the present invention is provided with a concave cavity A110 in the stop boss A11, and a through hole A111 communicating with the concave cavity A110 is provided on the upper surface of the stop boss A11; a groove 112 is provided on the inner top side of the concave cavity A110, and a guide sleeve 114 is connected to the bottom side of the groove 112 through a spring A113; a movable plate 115 is connected to the end of the guide sleeve 114, and an outer sleeve A116 is provided on the bottom side of the concave cavity 110, and an inner sleeve A118 sealingly matched with the outer sleeve A116 is connected to the bottom side of the outer sleeve A116 through a spring B117, and the top of the inner sleeve A118 is connected to the movable plate 115; the bottom end of the rain shield 13 is provided with a through hole A111 and a convex column A132 abutting against the movable plate 115; the outer sleeve A116, The inner sleeve A118 and the spring B117 constitute a telescopic module A; the inner wall of the L-shaped plate 12 is installed with a telescopic module B121, and the telescopic module B121 is connected to the telescopic module A; and the telescopic module B121 includes an outer sleeve B and an inner sleeve B that are sealed and matched with each other, and a spring C connected therebetween; and based on the above-mentioned mechanism, when the rain shield 13 moves downward and abuts against the upper surface of the stop boss A11, the boss A132 passes through the through hole A111 and abuts against the upper surface of the movable plate 115, and the inner sleeve A118 is controlled to move downward, and then the telescopic module B121 is driven to extend and abut against the outer wall of the rain shield 13 under the action of air pressure, thereby finally controlling the inner wall of the rain shield 13 to be tightly attached to the outer wall of the side panel 1.

[0049] At the same time, when in use, when there is a lot of dust, poplar fluff, etc. in the environment, in order to prevent dust, poplar fluff, etc. from entering the inside of the distribution cabinet through the ventilation holes 10, a liftable filtering structure is provided on the inner wall of the side panel 1 located at the ventilation holes 10, such as Figure 11-12 The filtering structure includes a rectangular frame 14 and filter screens 1410 arranged on both sides of the rectangular frame 14; that is, when the air entering the power distribution cabinet needs to be filtered during use, the filtering structure is controlled to move downward and block the ventilation hole 10.

[0050] It can be known that in order to facilitate the control of the up and down movement of the filtering structure, such as Figure 13-14 , through holes B142 are provided on both sides of the rectangular frame 14, and a stop boss B15 is provided on the inner wall of the side plate 1 below the ventilation hole 10; two protrusions 16 are provided on the inner wall of the side plate 1 below the ventilation hole 10, and a guide rod 17 is connected between the protrusion 16 and the stop boss B15, and the guide rod 17 movably passes through the hole B142, and a spring E18 sleeved on the outside of the guide rod 17 is connected between the protrusion 16 and the rectangular frame 14; and a traction rope B151 that passes through the stop boss B15 is also connected to the bottom end of the rectangular frame 14; Figure 4The upper surface of the base 2 is provided with a rotating disk B3b for moving by a traction rope B151; that is, when in use, when the air needs to be filtered, the rotating disk B3b is used to control the filter structure to move downward, and at the same time, in a natural state, the spring E18 is used to control the bottom end of the rectangular frame 14 to be higher than the top of the ventilation hole 10.

[0051] At the same time, in order to use the filter structure to filter the air entering the distribution cabinet, to prevent the air from entering the distribution cabinet through the gap formed by the filter structure and the inner wall of the side plate 1, as shown in FIG. Fig.12 An annular groove 143 is provided on one side of the rectangular frame 14, and a plurality of piston cavities 144 are provided on the bottom side of the annular groove 143. A movable column 146 sliding along the inner wall of the piston cavity 144 is provided in the piston cavity 144, and a sealing strip 145 is connected to the end of the movable column 146; Fig.17 , and a concave cavity B147 is provided at the bottom end of the rectangular frame 14, and a through hole B141 connected to the concave cavity B147 is provided at the bottom end of the rectangular frame 14, a piston cylinder 148 is installed in the through hole B141, and a piston 1483 sliding along the inner wall of the piston cylinder 148 is connected to the bottom side of the piston cylinder 148 through a spring D1482, and an opening 1481 connected to the concave cavity B147 is provided on the bottom side of the piston cylinder 148; the concave cavity B147 is connected to the piston cavity 144; and the stop boss The upper surface of B15 is provided with a boss B151 inserted into the piston cylinder 148; based on the above, when the filter structure is controlled to fall and abut against the stop boss B15 during use, the boss B151 is inserted into the piston cylinder 148 to press the piston 1483 to move upward, and then the movable column 146 in the concave cavity B147 is controlled to move along its own axial direction under the action of air pressure, thereby driving the sealing strip 145 to move toward the inner wall of the side panel 1 and then abut against the inner wall of the side panel 1.

[0052] In the present application, the rotating disk B3b and the rotating disk A3a provided by the present invention have the same structure, the end of the traction rope B151 is connected to the insertion mechanism B inserted into the insertion hole 31, and the structure of the insertion mechanism B and the insertion mechanism A are the same.

[0053] Specifically, Figure 5-7The rotating disk A3a includes a rotating disk body 3, on which four annular grooves 30 are arranged from top to bottom, and a socket 31 is arranged on the annular groove 30, in which an electromagnet 32 ​​is arranged; the end of the traction rope 130 is connected to an insertion mechanism A inserted into the socket 31, and the insertion mechanism A includes a magnetic column 35 inserted into the socket 31, and also includes a guide sleeve 33 fixed on the inner top side surface of the top cover 23, and the magnetic column 35 slides along the inner wall of the guide sleeve 33; and a protruding semicircular baffle 34 is provided at one end of the guide sleeve 33 close to the rotating disk body 3; when the magnetic column 35 is inserted into the socket 31, the end of the magnetic column 35 away from the rotating disk body 3 is placed on the semicircular baffle 34; a limiting ring 36 is fixed on the inner top side surface of the top cover 23 between the guide sleeve 33 and the side plate 1, and the traction rope 130 passes through the limiting ring 36, and the inner diameter of the limiting ring 36 is smaller than the diameter of the magnetic column 35.

[0054] On the basis of the above, in order to adapt to the different heights of the plug hole 31 at the rotating disk body 3, the central axis of the horizontal section of the traction rope B151 and the traction rope A130 can be collinear with the central axis of the plug hole 31, such as Figure 18-19 A support structure A for controlling the downward extension height of the traction rope B151 is provided at the bottom of the stop boss B15; at the same time, a support structure B for controlling the upward extension height of the traction rope A130 is provided on the inner wall of the side panel 1; the support structure B comprises an L-shaped mounting plate 4 mounted on the inner wall of the side panel 1, a vertical sleeve A41 is provided on the upper surface of the L-shaped mounting plate 4, a vertical rod A42 is movably inserted in the vertical sleeve A41, a locking bolt A43 is provided on the outer side of the vertical sleeve A41, and a circular hole A for controlling the passage of the traction rope A130 is provided at the end of the vertical rod A42; the support structure A comprises a base 5 mounted at the bottom of the stop boss B15, a vertical sleeve A51 is connected to the base 5, a vertical rod B52 is movably inserted in the vertical sleeve A51, a locking bolt B53 is provided on the outer side of the vertical sleeve A51, and a circular hole B for controlling the passage of the traction rope B151 is provided at the end of the vertical rod B52.

[0055] Based on the above, when the present invention is in use and needs to control a filter structure to move downward, an electromagnet 32 ​​in the rotating disk body 3 is controlled to be energized in the forward direction, and then under the attraction between the electromagnet 32 ​​and the magnetic column 35, the corresponding magnetic column 35 is controlled to slide along the inner wall of the guide sleeve 33 to be inserted into the corresponding socket 31 under the action of magnetic force. At this time, the rotating disk B3b is controlled to rotate, and then the action of the traction rope B151 is utilized to control the filter structure to move downward; when it is necessary to control the filter structure to move downward, the rotating disk B3b is controlled to rotate in the reverse direction until one end of the magnetic column 35 abuts against the semicircular baffle 34; at this time, the electromagnet 32 ​​is controlled to be energized in the reverse direction, that is, the positive and negative poles of the electromagnet 32 ​​are controlled to be switched, and then the magnetic column 35 and the electromagnet 32 ​​are repelled, and at this time, the magnetic column 35 moves outward along the inner wall of the socket 31 under the action of magnetic force.

[0056] Similarly, when controlling the rain shield 13 to move up and down, in a natural state, the magnetic column 35 at the rotating disk A3a is inserted into the insertion hole 31. When it is necessary to control a rain shield 13 to fall down, the rotating disk A3a is first controlled to rotate until all the rain shields 13 are released downward, and then an electromagnet 32 ​​in the rotating disk body 3 is controlled to be energized in the reverse direction. At this time, the magnetic column 35 and the electromagnet 32 ​​are used to produce a repulsive effect to control the magnetic column 35 to move outward along the inner wall of the insertion hole 31. At this time, the rain shield 13 is controlled to move downward under the action of gravity. Then, the control The rotating disk A3a is rotated until all the rain shields 13 are pulled up; when it is necessary to control the dropped rain shields 13 to be pulled up again, the rotating disk A3a is controlled to be rotated until all the rain shields 13 are released downward, and then the corresponding electromagnet 32 ​​is controlled to be energized in the forward direction, so that the electromagnet 32 ​​and the magnetic column 35 produce an attraction effect. At this time, under the action of magnetic force, the corresponding magnetic column 35 is controlled to slide along the inner wall of the guide sleeve 33 to be inserted into the corresponding socket 31, and the rotating disk A3a is controlled to be rotated until all the rain shields 13 are pulled up.

[0057] The upper surface of the base 2 and the inner top side surface of the top cover 23 are respectively provided with a driving structure A and a driving structure B which are connected to the rotating disk body 3 and drive the rotating disk body 3 to rotate. The driving structure A and the driving structure B are rotating motors, and the output end of the rotating motor is connected to one side of the rotating disk body 3.

[0058] It can be known that the rain shield 13 and the filter structure are selectively controlled to fall down according to the environmental conditions during use. A raindrop sensor, an air quality sensor and a wind direction detector are arranged in the environment during use. The raindrop sensor, the air quality sensor and the wind direction detector are connected to the controller, and the controller is connected to the driving structure A, the driving structure B, the rotating disk B3b and the rotating disk A3a.

[0059] Based on the settings of the above three sensors, when the raindrop sensor detects rain during use, the wind direction and wind speed are detected by the wind direction detector to determine whether rain can enter the distribution cabinet, and from which side of the distribution cabinet the rain enters; at the same time, when the air quality sensor detects that there is a lot of dust in the air, the wind direction and wind speed are detected by the wind direction detector to determine whether dust can enter the distribution cabinet, and from which side of the distribution cabinet the dust enters.
