Description

Technical Field

[0001] The invention belongs to the technical field of reactive power compensation cabinets, and particularly relates to an impact-resistant low-voltage complete set of reactive power compensation cabinets. Background Art

[0002] A low-voltage complete set of reactive power compensation cabinet is a dynamic reactive power compensation device specially designed for the low-voltage distribution network in the power system, which has the functions of improving the power factor and improving the power quality. When this compensation cabinet is connected to some electrical appliances with large instantaneous current during startup, such as motors or electric welders, an impact-resistant low-voltage complete set of reactive power compensation cabinets is required.

[0003] For example, the authorized invention with the authorization announcement number CN118899754B is in the technical field of split-type low-voltage reactive power compensation cabinets, and discloses a split-type low-voltage reactive power compensation cabinet, including a cabinet body, a cabinet door is hinged and installed on the front of the cabinet body, a dehumidification mechanism is arranged on the back of the cabinet body, a dehumidification box is fixedly installed on the back of the dehumidification mechanism, a dehumidification groove is opened in the dehumidification box, and further includes: two annular grooves are opened on the front inner wall of the dehumidification groove, two rotating rods are rotatably installed in the dehumidification groove, and cover-shaped activated carbon plates are respectively fixedly sleeved on the two rotating rods. In the invention, the heat in the cabinet body is discharged from two air outlets through blowing, so as to realize cooling and heat dissipation. When it is rainy outdoors, the air entering the dehumidification groove will be filtered and adsorbed by the cover-shaped activated carbon plates, so that the water molecules in the air are filtered down, and the air containing water molecules is prevented from entering the cabinet body to damage the electronic components in the cabinet body.

[0004] Combined with the above cases and the actual situation, we found the following problems: When such compensation cabinets are used outdoors and encounter rainy days, rainwater and water vapor may enter the cabinet body to damage the components or directly cause a short circuit. Therefore, a dehumidification device is usually provided. However, the existing dehumidification devices are usually directly arranged at the heat dissipation channels. During normal use, they will block the heat dissipation channels, seriously affecting heat dissipation. And when arranged outside the heat dissipation channels, the dehumidification effect will be reduced. Summary of the Invention

The outer ends of the limiting rods are embedded in the inner walls of the corresponding movable clamping plates and are slidably connected therewith. A return spring is sleeved between the inner ends of the limiting rods and the corresponding movable clamping plates.

[0010] In the technical solution of the present invention, a cleaning component for cleaning the dust-proof net is arranged between the front and rear side walls of the heat dissipation window. The cleaning component includes a cleaning plate arranged on the top surface of the heat dissipation window and clamping plates fixed to the front and rear sides of the cleaning plate. A clamping plate groove for the clamping plates to slide up and down is arranged in the cabinet body.

[0012] In the technical solution of the present invention, disassembly components for quickly disassembling and replacing the dehumidification component are provided on the outer walls of the left and right sides of the cabinet body. The disassembly components include a pressing plate arranged on the outer side wall of the cabinet body, a plurality of abutting plates corresponding to a plurality of movable clamping plates one by one, and a pressing strip structure corresponding to a plurality of abutting plates one by one.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: 1. In the present invention, by setting the dehumidification component, when it is drizzling, the rain-catching bucket will not flip, and at this time, the rotating rod will not drive the subsequent moisture-absorbing structure to move through the first rope to block the heat dissipation window from dissipating heat; when it is raining heavily, the drainage volume of the hose is small while the rainfall is large, and rainwater will quickly accumulate in the rain-catching bucket. At this time, due to the offset of the center of gravity of the rain-catching bucket, the rain-catching bucket and the rotating rod will rotate counterclockwise, thereby winding up the first rope to drive the rotating plate to rotate counterclockwise, and pulling the moisture-absorbing plate to slide up along the card strip groove to fit the heat dissipation window, preventing raindrops or a large amount of water vapor from entering the cabinet body. Under the action of the heat dissipation fan, the inhaled air passes through the moisture-absorbing plate and is dehumidified before entering the cabinet body to keep the inside dry. By setting the position of the moisture-absorbing plate according to the rainfall, it can dehumidify and avoid affecting the normal heat dissipation.

[0017] 2. In the present invention, by setting the cleaning component, when the moisture-absorbing plate slides up to absorb moisture, the driving tooth plate drives the driven tooth plate to slide down through the gear, thereby driving the card plate and the cleaning plate to slide down along the card plate groove, and then cleaning the dust-proof net to avoid dust accumulation affecting heat dissipation.

[0018] 3. In the present invention, by providing a disassembly component, when the moisture absorption capacity of the moisture absorption plate is insufficient, the buckle between the second rope and the moisture absorption plate is untied, and then the pressing plate is pressed to push the abutting plate forward to give an inward component force to the outer abutting strip, so that the entire pressing strip structure moves towards the movable clamping plate side, and further the inner abutting strip gives an inward component force to the movable clamping plate, causing the movable clamping plate to retract into the movable cavity. At this time, the moisture absorption plate can be separated and disassembled from the clamping strip groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following combines the accompanying drawings to describe the detailed implementation mode of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation mode.

[0021] Unless otherwise clearly stated, throughout the specification, the term "including" or its variations such as "comprising" or "including" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0022] Referring to Figures 1 - 18 As shown, this embodiment provides a technical solution: In the anti-impact low-voltage complete set of reactive power compensation cabinet of the present invention, it includes a cabinet assembly 1. The cabinet assembly 1 includes a cabinet 11 and heat dissipation windows 13 arranged on the left and right side walls of the cabinet 11. A heat dissipation fan 2 for active heat dissipation is fixed in the middle of the rear side wall of the cabinet 11. The heat dissipation fan 2 dissipates heat by suction. A dehumidification component 3 is provided at the top of the cabinet 11. The dehumidification component 3 can absorb water vapor during heavy rain to prevent damage to the internal components of the cabinet assembly 1. A dust-proof net 14 is fixed on the inner side of the heat dissipation window 13 to prevent dust through the setting of the dust-proof net 14; The dehumidification component 3 includes a rain-catching structure 31 for catching rainwater and a moisture-absorbing structure 32 for absorbing water vapor. The rain-catching structure 31 includes a rain-catching funnel 311 and a rotating rod 315 fixed to the middle of the bottom surface of the rain-catching funnel 311 through two symmetrically arranged upper supports 313 on the left and right. When not absorbing moisture, the rain-catching funnel 311 is inclined backward. Lower supports 314 are symmetrically fixed to the left and right of the top surface of the cabinet body 11. Both ends of the rotating rod 315 penetrate through the two upper supports 313 and are rotatably connected to the corresponding lower supports 314. Soft hoses 312 are symmetrically arranged on the front side of the bottom surface of the rain-catching funnel 311. First ropes 318 are respectively fixed to both ends of the rotating rod 315. When it rains lightly, at this time, due to the existence of the soft hoses 312, rainwater cannot be retained in the rain-catching funnel 311, and the rain-catching funnel 311 will not flip. Moreover, the internal components of the cabinet body assembly 1 itself have a certain degree of waterproofness and very little rainwater and water vapor can enter the cabinet body assembly 1. At the same time, due to the existence of the cooling fan 2, the water vapor can be quickly dried. At this time, the rotating rod 315 will not drive the subsequent moisture-absorbing structure 32 to move through the first ropes 318 to block the heat dissipation of the heat dissipation window 13; When there is a heavy rain, the drainage volume of the soft hoses 312 is small while the rainfall is large, and rainwater will quickly accumulate in the rain-catching funnel 311. At this time, due to the offset of the center of gravity of the rain-catching funnel 311, the rain-catching funnel 311 and the rotating rod 315 will be driven to rotate counterclockwise, thereby collecting the first ropes 318; Rotating plates 33 are symmetrically and rotatably connected to the upper parts of the left and right inner walls of the cabinet body 11. The bottom ends of the first ropes 318 are fixedly connected to the rotating shafts of the corresponding rotating plates 33. The moisture-absorbing structure 32 includes a moisture-absorbing plate 321, second ropes 322 respectively fixedly connected to the outer edges of the rotating plates 33 at the upper and lower ends and the middle of the moisture-absorbing plate 321, and two clamping mechanisms 323 fixed to the front and rear edges of the outer side walls of the moisture-absorbing plate 321. The second ropes 322 are bolted to the outer edges of the rotating plates 33 and the moisture-absorbing plates 321 with the same specifications of rope buckles (not shown in the figure. This is prior art and will not be elaborated here). Clamping grooves 15 corresponding to the clamping mechanisms 323 are provided on the inner wall of the cabinet body 11. When the first ropes 318 are collected, the rotating plates 33 will be driven to rotate counterclockwise, and then the moisture-absorbing plate 321 will be pulled along the clamping grooves 15 to slide upward and fit the heat dissipation window 13 to prevent raindrops or a large amount of water vapor from entering the cabinet body 11. Under the action of the cooling fan 2, the inhaled air passes through the moisture-absorbing plate 321 to absorb moisture and then enters the cabinet body 11.

[0023] In addition, as Figures 1 - 3As shown in the figure, the internal space of the rainwater receiving hopper 311 is in the shape of a frustum with a larger volume in the upper part and a smaller volume in the lower part, ensuring that the center of gravity is located on the front side of the rotating rod 315 after the rainwater receiving hopper 311 is filled with water, and thus can drive the rotating rod 315 to rotate counterclockwise. The top end of the hose 312 is communicated with the front side of the lower space of the rainwater receiving hopper 311. The diameter of the hose 312 is small. When there is light rain, the rainwater collected inside the rainwater receiving hopper 311 can quickly flow out from the hose 312. When there is heavy rain, the rainwater collected in the rainwater receiving hopper 311 cannot quickly flow out from the hose 312, so that the rainwater is retained in the rainwater receiving hopper 311, enabling the rainwater receiving hopper 311 to rotate. A sleeve 316 is sleeved on the outer wall of the rotating rod 315 between the two upper supports 313. The sleeve 316 is fixed to the top surface of the cabinet body 11. A clockwork spring 317 is provided between the sleeve 316 and the rotating rod 315. By providing the clockwork spring 317, the rainwater receiving hopper 311 can quickly rotate back after the rain stops and the water is drained, and at the same time, the rainwater receiving hopper 311 can be fixed during normal use to prevent the rainwater receiving hopper 311 from being blown by the wind.

[0024] Specifically, the left and right heat dissipation windows 13 are arranged in a staggered manner up and down to increase the heat dissipation area. The moisture absorption plate 321 is arranged on the inner wall of the corresponding cabinet body 11 and below the corresponding heat dissipation window 13. The left and right side walls of the moisture absorption plate 321 are provided with mesh openings and are filled with a number of interleaved silica gels inside. A number of purlins 4 are fixed outside the heat dissipation window 13. By providing the purlins 4, rainwater is assisted in being blocked. A cabinet door 12 is hinged to the front side of the cabinet body 11.

[0025] In addition, as Figures 4 - 10 shown, the clamping mechanism 323 includes a clamping bar 3231 and two movable clamping plates 3232 slidably connected to the front and rear sides of the clamping bar 3231. The movable clamping plates 3232 are telescopically arranged to facilitate the installation and disassembly of the entire moisture absorption plate 321. Activity cavities 3233 are symmetrically arranged inside the clamping bar 3231 in the front and rear directions. The inner sides of the movable clamping plates 3232 are slidably connected to the activity cavities 3233. Limit rods 3234 are symmetrically fixed up and down inside the activity cavities 3233. The outer ends of the limit rods 3234 are embedded in the inner walls of the corresponding movable clamping plates 3232 and are slidably connected thereto. A return spring 3235 is sleeved between the inner ends of the limit rods 3234 and the corresponding movable clamping plates 3232. By providing the return spring 3235, the movable clamping plates 3232 are pushed outwards during use, enabling the movable clamping plates 3232 to clamp the clamping bar groove 15, thereby limiting the moisture absorption plate 321.

[0026] In addition, as Figures 17 - 18As shown in the figure, a cleaning component 5 is provided between the front and rear side walls of the heat dissipation window 13. By setting the cleaning component 5, the dust-proof net 14 can be cleaned to prevent dust accumulation from affecting heat dissipation. The cleaning component 5 includes a cleaning plate 51 provided on the top surface of the heat dissipation window 13 and clamping plates 52 fixed on both the front and rear sides of the cleaning plate 51. The inner side of the cleaning plate 51 is closely attached to the dust-proof net 14. A clamping plate groove 16 for the clamping plates 52 to slide up and down is provided inside the cabinet body 11. By setting the clamping plates 52 and the clamping plate groove 16, the cleaning plate 51 is limited, enabling the cleaning plate 51 to slide up and down. A number of magnetic buttons 54 fixed to the top surface of the cleaning plate 51 and the top surface of the heat dissipation window 13 are provided. By setting the magnetic buttons 54, the cleaning plate 51 can be restricted on the top surface of the heat dissipation window 13 during normal use; Furthermore, a driving gear plate 324 is fixed in the middle of the outer side wall of the clamping strip 3231, and a driven gear plate 53 is fixed in the middle of the inner side wall of the clamping plate 52. A gear 18 is rotatably connected in the middle between the clamping strip groove 15 and the clamping plate groove 16. The driving gear plate 324 and the driven gear plate 53 are respectively engaged with the gear 18. When the second rope 322 pulls the moisture absorption plate 321 to slide up along the clamping strip groove 15, the driving gear plate 324 drives the driven gear plate 53 to slide downward through the gear 18, driving the clamping plate 52 and the cleaning plate 51 to slide downward along the clamping plate groove 16, thereby cleaning the dust-proof net 14.

[0027] In addition, as Figures 11 - 16 shown, a disassembly component 6 is provided on the outer walls of the left and right sides of the cabinet body 11. By setting the disassembly component 6, the dehumidification component 3 can be quickly disassembled and replaced, facilitating use. The disassembly component 6 includes a pressing plate 61 provided on the outer side wall of the cabinet body 11, a number of abutting plates 62 corresponding to a number of movable clamping plates 3232 one by one, and a pressing strip structure 63 corresponding to a number of abutting plates 62 one by one. By setting the disassembly component 6, the moisture absorption plate 321 can be quickly removed. The abutting plates 62 pass through the outer side wall of the cabinet body 11 and are slidably connected to the outer side wall of the cabinet body 11. A flange is fixed on the outer wall of the abutting plates 62, and the flange prevents the abutting plates 62 from detaching from the cabinet body 11, resulting in the entire disassembly component 6 being unusable.

[0028] Specifically, pressing grooves 17 are provided on both the left and right sides of the card strip groove 15 inside the cabinet body 11. The pressing strip structure 63 is arranged in the pressing groove 17. The pressing groove 17 communicates with the corresponding card strip groove 15. The pressing strip structure 63 is composed of an outer pressing strip 631 and an inner pressing strip 632 fixed to each other. The outer side surface of the outer pressing strip 631 is an inclined surface. The inner end surface of the pressing plate 62 is an inclined surface corresponding to the outer side surface of the outer pressing strip 631. The inner side surface of the inner pressing strip 632 is an inclined surface. The outer side surface of the movable clamping plate 3232 is an inclined surface with the same inclination as the inner side surface of the inner pressing strip 632. When the pressing plate 61 is pressed, the pressing plate 62 will be pushed forward to give the outer pressing strip 631 an inward component force, causing the entire pressing strip structure 63 to move toward the movable clamping plate 3232 side. Furthermore, the inner pressing strip 632 gives the movable clamping plate 3232 an inward component force, causing the movable clamping plate 3232 to retract into the movable cavity 3233. At this time, the moisture absorption plate 321 can be separated and disassembled from the card strip groove 15.

[0029] Furthermore, the left - right width of the outer pressing strip 631 is greater than that of the inner pressing strip 632. The outer pressing strip 631 is slidably connected to the pressing groove 17. During installation, the inclined surface of the movable clamping plate 3232 facilitates entering the card strip groove 15. At the same time, the inclined surface of the movable clamping plate 3232 will also push the inner pressing strip 632 outward, resetting the pressing strip structure 63 to prevent the outer pressing strip 631 from also entering the card strip groove 15, which may cause the pressing strip structure 63 to be unable to push outward when the movable clamping plate 3232 is installed.

[0030] The working principle of the impact - resistant low - voltage complete set of reactive power compensation cabinets in the present invention is specifically as follows: When it rains lightly, due to the presence of the hose 312, rainwater cannot be retained in the rain - receiving hopper 311. The rain - receiving hopper 311 will not flip. The internal components of the cabinet body assembly 1 itself have a certain degree of waterproofness, and very little raindrop moisture can enter the cabinet body assembly 1. At the same time, due to the presence of the cooling fan 2, the moisture can be quickly dried. At this time, the rotating rod 315 will not drive the subsequent moisture absorption structure 32 to move through the first rope 318 to block the heat dissipation of the heat dissipation window 13. When it rains heavily, the drainage volume of the hose 312 is small while the rainfall is large. Rainwater will quickly accumulate in the rain - receiving hopper 311. At this time, due to the offset of the center of gravity of the rain - receiving hopper 311, the rain - receiving hopper 311 and the rotating rod 315 will rotate counterclockwise, further winding up the first rope 318 to drive the rotating plate 33 to rotate counterclockwise. Then, through the second rope 322, the moisture absorption plate 321 is pulled to slide upward along the card strip groove 15 to fit the heat dissipation window 13, preventing raindrops or a large amount of water vapor from entering the cabinet body 11. Under the action of the cooling fan 2, the air inhaled passes through the moisture absorption plate 321 for moisture absorption and then enters the cabinet body 11 to keep the interior dry. When the moisture absorption plate 321 slides upward, the driving gear plate 324 drives the driven gear plate 53 to slide downward through the gear 18, driving the clamping plate 52 and the cleaning plate 51 to slide downward along the clamping plate groove 16, thereby cleaning the dust - proof net 14. When the moisture absorption capacity of the moisture absorption plate 321 decreases and needs to be replaced, untie the knot between the second rope 322 and the moisture absorption plate 321. Then, press the pressing plate 61 to push the abutting plate 62 forward, giving an inward component force to the outer abutting strip 631, causing the entire pressing strip structure 63 to move towards the movable clamping plate 3232 side. Further, the inner abutting strip 632 gives an inward component force to the movable clamping plate 3232, causing the movable clamping plate 3232 to retract into the movable cavity 3233. At this time, the moisture absorption plate 321 can be separated and disassembled from the clamping strip groove 15.
