Description

Technical Field

[0001] The invention relates to the technical field of capacitor cabinets, and in particular to a low-voltage capacitor cabinet with an instrument anti-interference structure. Background Art

[0002] Capacitor cabinet is a common power equipment. Currently, most capacitor cabinets with anti-interference effect are isolated by using partitions to improve the anti-interference effect. However, when the capacitor cabinet is put into operation, it will generate a lot of heat. After the partition isolates its equipment, the heat dissipation efficiency in the capacitor cabinet will deteriorate, which may easily cause safety hazards. Therefore, a low-voltage capacitor cabinet with an instrument anti-interference structure is proposed to facilitate automatic adjustment of the heat dissipation efficiency according to the temperature inside the capacitor cabinet, thereby improving convenience and safety. Summary of the invention

[0003] In view of the problems in the prior art, the present invention provides a low-voltage capacitor cabinet with an instrument anti-interference structure, which is convenient for automatically adjusting the heat dissipation efficiency according to the temperature inside the capacitor cabinet, thereby improving the convenience and safety of use.

[0004] The technical solution adopted by the present invention to solve its technical problems is a low-voltage capacitor cabinet with an instrument anti-interference structure, including a cabinet body, a plurality of groups of vertically arranged first partitions are provided in the cabinet body, a plurality of groups of horizontally arranged second partitions are provided in the cabinet body, a plurality of groups of second partitions are staggered with a plurality of groups of first partitions, a plurality of groups of through-openings are provided on each of the second partitions, the cabinet body is divided into a plurality of heat dissipation channels by a plurality of groups of first partitions, a plurality of groups of adjustable heat dissipation structures corresponding to the heat dissipation channels are provided on the top of the cabinet body, an air outlet structure is provided on the top of the cabinet body, and the air outlet structure is communicated with the inside of the cabinet body.

[0005] By adopting the above technical solution, after the electrical components in the capacitor cabinet are installed, when the capacitor cabinet is put into use, the electrical components inside the capacitor cabinet will generate a large amount of heat, thereby increasing the temperature in the heat dissipation channel. By driving the air outlet structure to draw suction inside the cabinet, the heat generated by the electrical components moves upward through the openings and the heat dissipation channel. When the heat in the heat dissipation channel passes through the adjustable heat dissipation structure, the heat dissipation efficiency in different heat dissipation channels can be automatically adjusted by the adjustable heat dissipation structure according to the temperature in different heat dissipation channels.

[0006] After the adjustable heat dissipation structure is adjusted, the inside of the cabinet is finally cooled by the suction effect generated by the air outlet structure, so that the heat dissipation efficiency in different heat dissipation channels can be automatically adjusted according to the use of electrical components in different heat dissipation channels, thereby improving the convenience and safety of use;

[0007] The first partition and the second partition are used to separate the adjacent electrical components, thereby reducing the electromagnetic interference between the adjacent electrical components and improving the anti-interference effect of the capacitor cabinet;

[0008] It should be pointed out that the first partition and the second partition described in the present invention are both metal partitions.

[0009] Specifically, the adjustable heat dissipation structure includes fixed plates respectively installed on the top of the inner side of the heat dissipation channel, the fixed plates are provided with a plurality of groups of first air outlet holes corresponding to the heat dissipation channels, the first air outlet holes are arranged through the fixed plates, and the first air outlet holes are connected with the heat dissipation channels;

[0010] The upper surface of the fixed plate is sealingly and slidably connected to a movable plate, a second air outlet hole corresponding to the first air outlet hole is provided on the movable plate, a first piston cylinder is provided on one side of the movable plate, a first piston rod is sealingly and slidably connected in the first piston cylinder, one end of the first piston rod is fixedly connected to the movable plate, the first piston cylinder is fixedly connected to the upper surface of the fixed plate, the second air outlet hole is initially arranged alternately with the first air outlet hole, a chamber is provided inside the fixed plate, the chamber is filled with a thermal expansion fluid, and the chamber is connected to the inside of the first piston cylinder through a first connecting pipe.

[0011] By adopting the above technical solution, when the heat generated by the electrical components moves to a certain position through the heat dissipation channel, the heat in the heat dissipation channel is discharged by relying on the first air outlet and the second air outlet, and finally the heat generated by the electrical components inside the cabinet is discharged through the air outlet structure, so as to facilitate heat dissipation inside the cabinet;

[0012] When the heat generated by the electrical component is large, the temperature in the heat dissipation channel also becomes high. When the heat in the heat dissipation channel passes through the first air outlet on the fixed plate, the thermal expansion fluid in the chamber of the fixed plate expands, and the thermal expansion fluid in the chamber is transported to the first piston cylinder by relying on the first connecting pipe, thereby squeezing the inside of the first piston cylinder and driving the first piston rod to move. When the first piston rod moves, it drives the movable plate to move, so that the second air outlet on the movable plate corresponds to the first air outlet, so as to facilitate automatic adjustment of the relative position of the second air outlet and the first air outlet according to the temperature in different heat dissipation channels, thereby improving the air outlet effect and heat dissipation efficiency, and further improving the convenience of use.

[0013] Specifically, a second piston cylinder is installed on the fixed plate, the second piston cylinder is located on the side of the movable plate away from the first piston cylinder, a second piston rod is sealingly and slidingly connected inside the second piston cylinder, the second piston rod is fixedly connected to one side of the movable plate, several groups of the second piston cylinders are filled with hydraulic oil, and adjacent second piston cylinders are connected through second connecting pipes.

[0014] By adopting the above technical solution, when the temperature in a group of heat dissipation channels is high, the first piston cylinder is squeezed and the first piston rod is driven to move. When the first piston rod moves, the movable plate is driven to move, so as to adjust the relative position of the second air outlet and the first air outlet in the corresponding heat dissipation channel, thereby improving the heat dissipation efficiency;

[0015] At the same time, when the first piston rod drives the movable plate to move, the movable plate squeezes the second piston rod to move, and the second piston rod squeezes the inside of the second piston cylinder when it moves, relying on the second connecting pipe between adjacent second piston cylinders. When a group of second piston cylinders are squeezed, the hydraulic oil inside the second piston cylinder enters into other second piston cylinders through the second connecting pipe, and squeezes the inside of other second piston cylinders, thereby moving the second piston rods inside other second piston cylinders, and relying on the second piston rod to drive the movable plate to move, so that the overlap effect of the second air outlet holes on other movable plates and the first air outlet holes is reduced, and the air outlet of other heat dissipation channels is reduced, so as to facilitate the rapid heat dissipation of a group of heat dissipation channels with higher temperatures, so that the heat dissipation efficiency in the corresponding heat dissipation channel can be automatically adjusted according to the actual temperature changes in the heat dissipation channel.

[0016] Specifically, the air outlet structure includes a driving motor installed on the top of the cabinet, the output end of the driving motor passes through the cabinet and is rotatably connected to the cabinet, the lower end of the driving motor is connected to a driving shaft, and a plurality of groups of circumferentially distributed first blades are provided on the outer side of the driving shaft. A ventilation window is provided on the top of the cabinet, and the ventilation window is connected to the interior of the cabinet.

[0017] By adopting the above technical solution, the driving motor drives the driving shaft to rotate, and when the driving shaft rotates, it drives several groups of first blades to rotate. When the first blades rotate, a suction effect is generated inside the cabinet, so that the heat generated in the heat dissipation channel is discharged through the ventilation window.

[0018] Specifically, two groups of symmetrically arranged air outlet adjustment structures are arranged inside the cabinet, and the air outlet adjustment structure includes a horizontally arranged rotating rod, a protective window is arranged on the outside of the cabinet, one end of the rotating rod passes through the cabinet and is located in the protective window, the rotating rod is rotatably connected to the cabinet, and a plurality of groups of circumferentially distributed second blades are arranged on the outside of one end of the rotating rod close to the protective window, and an air outlet window corresponding to the protective window is opened on the side of the cabinet;

[0019] A sliding groove is provided at one end of the rotating rod away from the second blade, a moving rod is slidably connected in the sliding groove, a limiting groove is provided inside the rotating rod, a limiting block corresponding to the limiting groove is provided on the outer side of the moving rod, and the limiting block is located in the limiting groove and slidably connected to the limiting groove;

[0020] The lower end of the driving shaft is fixedly connected with a first bevel gear, and the end of the moving rod away from the rotating rod is fixedly connected with a second bevel gear, and the second bevel gear is meshed with the first bevel gear for transmission. An adjustable driving structure is provided below the rotating rod, and the adjustable driving structure is used to drive the moving rod to move.

[0021] By adopting the above technical solution, when the temperature inside the cabinet is high, the rotation of the first blade cannot meet the heat dissipation demand, and the movable rod is driven to move by relying on the adjustable driving structure. When the movable rod moves, the limit block is driven to slide and connect with the limit groove. When the movable rod moves to a certain position, the second bevel gear at one end of the movable rod is meshed and transmitted with the first bevel gear at the lower end of the driving shaft, thereby driving the movable rod to rotate. When the movable rod rotates, the limit block is used to drive the rotating rod to rotate. When the rotating rod rotates, the second blade is driven to rotate. When the second blade rotates, the air outlet window is used to further improve the heat dissipation efficiency in the cabinet. In this way, when the cabinet temperature is high, the two sets of second blades can be automatically rotated, thereby further improving the convenience of use and the safety of the cabinet.

[0022] The second blade can be protected by the protective window, and the overall aesthetics of the cabinet can be improved.

[0023] Specifically, the adjustable driving structure includes a fixed cylinder, one end of which is fixedly connected to the inner wall of the cabinet, a sealing plate is sealingly and slidably connected inside the fixed cylinder, a horizontally arranged cross bar is provided on one side of the sealing plate, an end of the cross bar away from the sealing plate passes through the fixed cylinder and is connected to a connecting plate, a card slot is provided on the connecting plate, and one end of the moving rod passes through the card slot and is rotatably connected to the card slot;

[0024] A magnet is fixedly connected inside the fixed cylinder, and the magnet is located on the inner wall of the sealing plate away from the cross bar. The sealing plate is magnetically affinity, and the magnet is magnetically attracted to the sealing plate. A return spring is fixedly connected between the side of the sealing plate away from the cross bar and the inner wall of the fixed cylinder;

[0025] A liquid outlet joint is provided at the top of the second piston cylinder, and the liquid outlet joint is connected to the interior of the second piston cylinder. A liquid inlet joint is provided below the fixed cylinder, and the liquid inlet joint is connected to the interior of an end of the fixed cylinder away from the connecting plate. The liquid outlet joint is connected to the liquid inlet joint through a pipeline.

[0026] By adopting the above technical scheme, when the temperatures of several groups of heat dissipation channels inside the cabinet are all increased, the temperature increase drives several groups of first piston rods to move, and when several groups of first piston rods move, they respectively drive the corresponding moving plates to move, and when several groups of moving plates move, they respectively drive the corresponding second piston rods to move, so as to squeeze the inside of several groups of second piston cylinders. Since adjacent second piston cylinders are connected through the second connecting pipe, the hydraulic oil inside the second piston cylinder is transported to the fixed cylinder by means of the liquid outlet joint, the pipeline, and the liquid inlet joint, and the inside of the fixed cylinder is squeezed, and the sealing plate is driven to move at the same time. When the sealing plate moves, it is separated from the magnet and no longer adsorbed, and the reset spring is driven to move and accumulate force. When the sealing plate moves, it drives the cross bar to move synchronously, and when the cross bar moves, it drives the connecting plate to move. When the connecting plate moves, it drives the moving rod to move by the action of the card slot. When the moving rod moves to a certain position, the second bevel gear at one end of the moving rod meshes with the first bevel gear for transmission, thereby driving the second blade to rotate, so as to improve the heat dissipation efficiency inside the cabinet, further improve the use safety, and facilitate automatic adjustment of the heat dissipation efficiency according to the actual temperature changes inside the cabinet.

[0027] When the temperature inside the cabinet drops, the squeezing force of the thermal expansion fluid on the first piston rod decreases, thereby reducing the pressure on the hydraulic oil in the second piston cylinder. At this time, the sealing plate is driven to reset and move by relying on the reset effect of the reset spring. After the sealing plate is reset and moved to this state, the sealing plate and the magnet are magnetically adsorbed again, and at the same time, the hydraulic oil in the fixed cylinder is transported to the second piston cylinder through the pipeline by relying on the reset movement of the sealing plate; the second piston rod is driven to move by relying on the hydraulic oil squeezing the second piston cylinder, and the movable plate is driven to move by relying on the cooperation of the first piston rod and the second piston rod, so that the movable plate is moved to the corresponding position, thereby further improving the convenience of use.

[0028] Specifically, the adsorption force of the magnets in one group of the fixed cylinders is greater than the adsorption force of the magnets in another group of the fixed cylinders.

[0029] By adopting the above technical solution, when all the groups of second piston cylinders are squeezed, the hydraulic oil in the groups of second piston cylinders is transported to the two groups of fixed cylinders through pipelines, and squeezes the inside of the two groups of fixed cylinders. Due to the different adsorption forces of the magnets in the two groups of fixed cylinders, the sealing plate in the group of fixed cylinders with smaller adsorption forces of the magnets will be squeezed out by the hydraulic oil first, and the sealing plate will be driven to move. When the sealing plate moves, the cross bar will be driven to move, thereby starting the rotation of the group of second blades, thereby improving the heat dissipation efficiency of the cabinet.

[0030] After a group of second blades rotate, if the heat dissipation efficiency is still not satisfied, the hydraulic oil will continue to be squeezed and the pressure will be further increased, thereby continuing to squeeze the other group of fixed cylinders, so that the group of magnets with greater magnet adsorption force is no longer magnetically adsorbed to the sealing plate, and drives the other group of sealing plates to move, and drives the other group of second blades to rotate, so as to automatically start one or two groups of second blades to rotate according to the temperature inside the cabinet and the actual heat dissipation conditions, thereby improving the heat dissipation efficiency of the cabinet.

[0031] Specifically, a cabinet door is hinged on the outer side of the cabinet body, and an insulating partition is detachably connected to a side of the cabinet door close to the cabinet body.

[0032] By adopting the above technical solution and closing the cabinet door, the anti-interference effect inside the capacitor cabinet can be further improved by relying on the insulating partition.

[0033] Beneficial effects of the present invention:

[0034] (1) The present invention discloses a low-voltage capacitor cabinet with an instrument anti-interference structure. When the heat generated by the electrical components is large, the heat in the heat dissipation channel expands according to the thermal expansion fluid in the chamber of the fixed plate when passing through the first air outlet on the fixed plate, and the thermal expansion fluid in the chamber is transported to the first piston cylinder by the first connecting pipe, and the first piston rod is driven to move. When the first piston rod moves, the movable plate is driven to move, so that the second air outlet on the movable plate corresponds to the first air outlet, so that the relative position of the second air outlet and the first air outlet is automatically adjusted according to the temperature in different heat dissipation channels, thereby improving the air outlet effect and heat dissipation efficiency.

[0036] (3) The low-voltage capacitor cabinet with an instrument anti-interference structure described in the present invention has a structure in which, when the temperatures of several groups of heat dissipation channels inside the cabinet are all increased, several groups of first piston rods move and respectively drive the corresponding moving plates to move, thereby squeezing the inside of several groups of second piston cylinders, and the hydraulic oil inside the second piston cylinders is transported to the fixed cylinder by means of the liquid outlet joint, pipeline, and liquid inlet joint. After the moving rod is driven to move to a certain position by the sealing plate, the second bevel gear at one end of the moving rod meshes with the first bevel gear for transmission, thereby driving the second blade to rotate, thereby improving the heat dissipation efficiency inside the cabinet, further improving the safety of use, and facilitating the automatic adjustment of the heat dissipation efficiency according to the actual temperature changes inside the cabinet.

DETAILED DESCRIPTION

[0050] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0051] In order to automatically adjust the heat dissipation efficiency according to the temperature inside the capacitor cabinet, as an embodiment of the present invention, Figure 1 , Figure 2 As shown, a low-voltage capacitor cabinet with an instrument anti-interference structure described in the present invention includes a cabinet body 1, wherein a plurality of groups of vertically arranged first partitions 2 are arranged in the cabinet body 1, a plurality of groups of horizontally arranged second partitions 3 are arranged in the cabinet body 1, a plurality of groups of second partitions 3 are staggered with a plurality of groups of first partitions 2, a plurality of groups of through-set openings 4 are arranged on the second partitions 3, the cabinet body 1 is divided into a plurality of groups of heat dissipation channels 5 by a plurality of groups of first partitions 2, a plurality of groups of adjustable heat dissipation structures corresponding to the heat dissipation channels 5 are arranged on the top of the cabinet body 1, an air outlet structure is arranged on the top of the cabinet body 1, and the air outlet structure is communicated with the interior of the cabinet body 1.

[0052] When in use, after the electrical components in the capacitor cabinet are installed and put into use, the electrical components inside the capacitor cabinet will generate a large amount of heat, thereby increasing the temperature in the heat dissipation channel 5. By driving the air outlet structure to draw suction inside the cabinet body 1, the heat generated by the electrical components moves upward through the opening 4 and the heat dissipation channel 5. When the temperature of the heat dissipation channel 5 passes through the adjustable heat dissipation structure, the heat dissipation efficiency in different heat dissipation channels 5 can be automatically adjusted according to the temperature in different heat dissipation channels 5 by relying on the adjustable heat dissipation structure;

[0053] After the adjustable heat dissipation structure is adjusted, the inside of the cabinet 1 is finally cooled by the suction effect generated by the air outlet structure, so that the heat dissipation efficiency in different heat dissipation channels 5 can be automatically adjusted according to the use of electrical components in different heat dissipation channels 5, thereby improving the convenience and safety of use;

[0054] The first partition 2 and the second partition 3 are used to separate the adjacent electrical components, thereby reducing the electromagnetic interference between the adjacent electrical components and improving the anti-interference effect of the capacitor cabinet;

[0055] It should be pointed out that the first partition plate 2 and the second partition plate 3 described in the present invention are both metal partition plates.

[0056] In order to improve the air outlet effect and heat dissipation efficiency, for example, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes that the adjustable heat dissipation structure includes fixing plates 6 respectively installed on the top of the inner side of the heat dissipation channel 5, and the fixing plates 6 are provided with a plurality of groups of first air outlet holes 7 corresponding to the heat dissipation channel 5, and the first air outlet holes 7 are arranged through the fixing plates 6, and the first air outlet holes 7 are communicated with the heat dissipation channel 5;

[0057] The upper surface of the fixed plate 6 is sealingly and slidably connected with a movable plate 8, and the movable plate 8 is provided with a second air outlet hole 9 corresponding to the first air outlet hole 7. A first piston cylinder 10 is provided on one side of the movable plate 8, and a first piston rod 11 is sealingly and slidably connected inside the first piston cylinder 10. One end of the first piston rod 11 is fixedly connected to the movable plate 8, and the first piston cylinder 10 is fixedly connected to the upper surface of the fixed plate 6. The second air outlet hole 9 is initially staggered with the first air outlet hole 7. A chamber 12 is provided inside the fixed plate 6, and the chamber 12 is filled with a thermal expansion fluid. The chamber 12 is connected to the inside of the first piston cylinder 10 through a first connecting pipe 13.

[0058] When in use, after the heat generated by the electrical components moves to a certain position through the heat dissipation channel 5, the heat in the heat dissipation channel 5 is discharged by the first air outlet 7 and the second air outlet 9, and finally the heat generated by the electrical components inside the cabinet 1 is discharged through the air outlet structure, so as to facilitate heat dissipation inside the cabinet 1;

[0059] When the heat generated by the electrical components is large, the temperature in the heat dissipation channel 5 also becomes high. When the temperature in the heat dissipation channel 5 passes through the first air outlet 7 on the fixed plate 6, the heat expansion fluid in the chamber 12 of the fixed plate 6 expands, and the first connecting pipe 13 is used to transport the heat expansion fluid in the chamber 12 to the first piston cylinder 10, thereby squeezing the inside of the first piston cylinder 10 and driving the first piston rod 11 to move. When the first piston rod 11 moves, it drives the movable plate 8 to move, so that the second air outlet 9 on the movable plate 8 corresponds to the first air outlet 7, so as to facilitate the automatic adjustment of the relative position of the second air outlet 9 and the first air outlet 7 according to the temperature in different heat dissipation channels 5, thereby improving the air outlet effect and heat dissipation efficiency, and further improving the convenience of use.

[0060] In order to automatically adjust the heat dissipation efficiency in the corresponding heat dissipation channel 5 according to the actual temperature change in the heat dissipation channel 5, for example, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the present invention also includes that a second piston cylinder 14 is installed on the fixed plate 6, the second piston cylinder 14 is located on the side of the movable plate 8 away from the first piston cylinder 10, the second piston cylinder 14 is sealed and slidably connected with a second piston rod 15 inside, the second piston rod 15 is fixedly connected to one side of the movable plate 8, several groups of the second piston cylinders 14 are filled with hydraulic oil, and adjacent second piston cylinders 14 are connected through second connecting pipes 16.

[0061] When in use, when the temperature in a group of heat dissipation channels 5 is high, the first piston cylinder 10 is squeezed and the first piston rod 11 is driven to move. When the first piston rod 11 moves, the moving plate 8 is driven to move, so as to adjust the relative position of the second air outlet 9 and the first air outlet 7 in the corresponding heat dissipation channel 5, thereby improving the heat dissipation efficiency;

[0062] At the same time, when the first piston rod 11 drives the movable plate 8 to move, the movable plate 8 squeezes the second piston rod 15 to move. When the second piston rod 15 moves, it squeezes the inside of the second piston cylinder 14, and the adjacent second piston cylinders 14 are connected through the second connecting pipe 16. When the inside of a group of second piston cylinders 14 is squeezed, the hydraulic oil inside the second piston cylinder 14 enters into the other second piston cylinders 14 through the second connecting pipe 16, and squeezes the inside of the other second piston cylinders 14, so that the second piston rod 15 inside the other second piston cylinders 14 moves, and the movable plate 8 is driven to move by the second piston rod 15, so that the overlap effect of the second air outlet 9 on the other movable plates 8 and the first air outlet 7 is reduced, and the air outlet of other heat dissipation channels 5 is reduced, so as to facilitate the rapid heat dissipation of a group of heat dissipation channels 5 with higher temperatures, so that the heat dissipation efficiency in the corresponding heat dissipation channel 5 can be automatically adjusted according to the actual temperature changes in the heat dissipation channel 5.

[0063] For example, Figure 1 , Figure 2 , Figure 8 As shown, the present invention also includes that the air outlet structure includes a driving motor 17 installed on the top of the cabinet 1, the output end of the driving motor 17 passes through the cabinet 1 and is rotatably connected to the cabinet 1, the lower end of the driving motor 17 is connected to a driving shaft 18, and the outer side of the driving shaft 18 is provided with a plurality of groups of circumferentially distributed first blades 19, and the top of the cabinet 1 is provided with a ventilation window 20, and the ventilation window 20 is connected to the inside of the cabinet 1.

[0064] When in use, the driving motor 17 drives the driving shaft 18 to rotate, and the driving shaft 18 drives a plurality of groups of first blades 19 to rotate. When the first blades 19 rotate, a suction effect is generated inside the cabinet 1, so that the heat generated in the heat dissipation channel 5 is discharged through the ventilation window 20.

[0065] In order to further improve the heat dissipation efficiency in the cabinet 1, for example, Figure 7 , Figure 8 , Fig.11 As shown, the present invention also includes that two groups of symmetrically arranged air outlet adjustment structures are arranged inside the cabinet 1, and the air outlet adjustment structure includes a horizontally arranged rotating rod 21, and a protective window 22 is arranged on the outside of the cabinet 1, one end of the rotating rod 21 passes through the cabinet 1 and is located in the protective window 22, and the rotating rod 21 is rotatably connected to the cabinet 1, and a plurality of groups of circumferentially distributed second blades 23 are arranged on the outside of one end of the rotating rod 21 close to the protective window 22, and an air outlet window 24 corresponding to the protective window 22 is opened on the side of the cabinet 1;

[0066] The end of the rotating rod 21 away from the second blade 23 is provided with a sliding groove 25 penetrating therethrough, and a moving rod 26 is slidably connected in the sliding groove 25. A limiting groove 27 is provided inside the rotating rod 21, and a limiting block 28 corresponding to the limiting groove 27 is provided on the outer side of the moving rod 26. The limiting block 28 is located in the limiting groove 27 and is slidably connected to the limiting groove 27.

[0067] The lower end of the driving shaft 18 is fixedly connected with a first bevel gear 29, and the end of the moving rod 26 away from the rotating rod 21 is fixedly connected with a second bevel gear 30, and the second bevel gear 30 is meshed with the first bevel gear 29 for transmission. An adjustable driving structure is provided below the rotating rod 21, and the adjustable driving structure is used to drive the moving rod 26 to move.

[0068] When in use, when the temperature inside the cabinet 1 is high, the rotation of the first blade 19 cannot meet the heat dissipation demand. The movable rod 26 is driven to move by the adjustable driving structure. When the movable rod 26 moves, the limit block 28 is driven to slide and connect with the limit groove 27. When the movable rod 26 moves to a certain position, the second bevel gear 30 at one end of the movable rod 26 is meshed and transmitted with the first bevel gear 29 at the lower end of the drive shaft 18, thereby driving the movable rod 26 to rotate. When the movable rod 26 rotates, the rotation rod 21 is driven to rotate by the action of the limit block 28. When the rotation rod 21 rotates, the second blade 23 is driven to rotate. When the second blade 23 rotates, the action of the air outlet window 24 can be relied on to further improve the heat dissipation efficiency in the cabinet 1. In this way, when the temperature of the cabinet 1 is high, the two sets of second blades 23 can be automatically rotated, thereby further improving the convenience of use and the safety of the cabinet 1.

[0069] The second blade 23 can be protected by the protective window 22 , and the overall aesthetics of the cabinet 1 can be improved.

[0070] In order to automatically adjust the heat dissipation efficiency according to the actual temperature change inside the cabinet 1, Figure 4 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 As shown, the present invention also includes that the adjustable driving structure includes a fixed cylinder 31, one end of the fixed cylinder 31 is fixedly connected to the inner wall of the cabinet 1, and a sealing plate 32 is sealed and slidably connected inside the fixed cylinder 31, and a horizontally arranged cross bar 33 is provided on one side of the sealing plate 32, and one end of the cross bar 33 away from the sealing plate 32 passes through the fixed cylinder 31 and is connected to a connecting plate 34, and a card slot is provided on the connecting plate 34, and one end of the moving rod 26 passes through the card slot and is rotatably connected to the card slot;

[0071] A magnet 35 is fixedly connected inside the fixed cylinder 31. The magnet 35 is located on the inner wall of the sealing plate 32 away from the cross bar 33. The sealing plate 32 is magnetically affinity. The magnet 35 is magnetically attracted to the sealing plate 32. A return spring 36 is fixedly connected between the inner wall of the fixed cylinder 31 and the side of the sealing plate 32 away from the cross bar 33.

[0072] A liquid outlet joint 37 is provided at the top of the second piston cylinder 14, and the liquid outlet joint 37 is connected to the interior of the second piston cylinder 14. A liquid inlet joint 39 is provided below the fixed cylinder 31, and the liquid inlet joint 39 is connected to the interior of an end of the fixed cylinder 31 away from the connecting plate 34. The liquid outlet joint 37 is connected to the liquid inlet joint 39 through a pipeline 38.

[0073] During use, when the temperatures of the several groups of heat dissipation channels 5 inside the cabinet 1 all rise, the temperature rise drives the several groups of first piston rods 11 to move, and when the several groups of first piston rods 11 move, they respectively drive the corresponding moving plates 8 to move, and when the several groups of moving plates 8 move, they respectively drive the corresponding second piston rods 15 to move, thereby squeezing the inside of the several groups of second piston cylinders 14. Since the adjacent second piston cylinders 14 are connected through the second connecting pipe 16, the hydraulic oil inside the second piston cylinder 14 is transported to the fixed cylinder 31 by means of the liquid outlet joint 37, the pipeline 38, and the liquid inlet joint 39, and squeezes the inside of the fixed cylinder 31, and drives The sealing plate 32 moves, and when the sealing plate 32 moves, it is separated from the magnet 35 and no longer adsorbed, and at the same time drives the reset spring 36 to move and store force. When the sealing plate 32 moves, it drives the cross bar 33 to move synchronously, and when the cross bar 33 moves, it drives the connecting plate 34 to move. When the connecting plate 34 moves, it drives the moving rod 26 to move by the action of the card slot. When the moving rod 26 moves to a certain position, the second bevel gear 30 at one end of the moving rod 26 meshes with the first bevel gear 29 for transmission, thereby driving the second blade 23 to rotate, thereby improving the heat dissipation efficiency inside the cabinet 1, further improving the use safety, and facilitating the automatic adjustment of the heat dissipation efficiency according to the actual temperature change inside the cabinet 1;

[0074] When the temperature inside the cabinet 1 drops, the squeezing force of the thermal expansion fluid on the first piston rod 11 decreases, thereby reducing the pressure on the hydraulic oil in the second piston cylinder 14. At this time, the sealing plate 32 is reset and moved by relying on the reset effect of the reset spring 36. After the sealing plate 32 is reset and moved to this state, the sealing plate 32 and the magnet 35 are magnetically adsorbed again, and at the same time, relying on the reset movement of the sealing plate 32, the hydraulic oil in the fixed cylinder 31 is transported to the second piston cylinder 14 through the pipeline 38; relying on the hydraulic oil squeezing the second piston cylinder 14 to drive the second piston rod 15 to move, and relying on the cooperation of the first piston rod 11 and the second piston rod 15 to drive the movable plate 8 to move, so that the movable plate 8 is moved to the corresponding position, thereby further improving the convenience of use.

[0075] Exemplarily, the present invention also includes that the adsorption force of the magnets 35 in one group of the fixing cylinders 31 is greater than the adsorption force of the magnets 35 in another group of the fixing cylinders 31 .

[0076] When in use, when all the groups of second piston cylinders 14 are squeezed, the hydraulic oil in the groups of second piston cylinders 14 is transported to the two groups of fixed cylinders 31 through the pipeline 38, and squeezes the inside of the two groups of fixed cylinders 31. Due to the different adsorption forces of the magnets 35 in the two groups of fixed cylinders 31, the sealing plate 32 in the group of fixed cylinders 31 with the smaller adsorption force of the magnets 35 will be squeezed out by the hydraulic oil first, and the sealing plate 32 will be driven to move. When the sealing plate 32 moves, the cross bar 33 will be driven to move, thereby starting the rotation of the group of second blades 23, thereby improving the heat dissipation efficiency of the cabinet 1;

[0077] After one group of second blades 23 rotates, if the heat dissipation efficiency is still not satisfied, the hydraulic oil will continue to be squeezed and the pressure will be further increased, thereby continuing to squeeze the other group of fixed cylinders 31, so that the magnets 35 with a larger adsorption force are no longer magnetically adsorbed to the sealing plate 32, and drive the other group of sealing plates 32 to move, and drive the other group of second blades 23 to rotate, so as to automatically start one or two groups of second blades 23 to rotate according to the temperature inside the cabinet 1 and the actual heat dissipation conditions, thereby improving the heat dissipation efficiency of the cabinet 1.

[0078] For example, Figure 1 As shown, the present invention further includes that a cabinet door 40 is hingedly connected to the outer side of the cabinet body 1 , and an insulating partition 41 is detachably connected to a side of the cabinet door 40 close to the cabinet body 1 .

[0079] When in use, the cabinet door 40 is closed, and the anti-interference effect inside the capacitor cabinet can be further improved by relying on the insulating partition 41.

[0080] When the present invention is in use, after the electrical components in the capacitor cabinet are installed and the capacitor cabinet is put into use, the electrical components inside the capacitor cabinet will generate a large amount of heat, thereby increasing the temperature in the heat dissipation channel 5. When the temperature in the heat dissipation channel 5 passes through the first air outlet 7 on the fixed plate 6, the heat expansion fluid in the chamber 12 of the fixed plate 6 expands, and the heat expansion fluid in the chamber 12 is transported to the first piston cylinder 10 by means of the first connecting pipe 13, thereby squeezing the inside of the first piston cylinder 10 and driving the first piston rod 11 to move. When the first piston rod 11 moves, it drives the movable plate 8 to move, so that the second air outlet 9 on the movable plate 8 corresponds to the first air outlet 7, so that the relative position of the second air outlet 9 and the first air outlet 7 is automatically adjusted according to the temperature in different heat dissipation channels 5, thereby improving the air outlet effect and heat dissipation efficiency, and further improving the convenience of use;

[0081] The driving motor 17 drives the driving shaft 18 to rotate, and when the driving shaft 18 rotates, it drives a plurality of groups of first blades 19 to rotate. When the first blades 19 rotate, a suction effect is generated inside the cabinet 1, so that the heat generated in the heat dissipation channel 5 is discharged through the ventilation window 20;

[0082] When the temperature in a group of heat dissipation channels 5 is high, the first piston cylinder 10 is squeezed and the first piston rod 11 is driven to move. When the first piston rod 11 moves, the movable plate 8 is driven to move, so as to adjust the relative position of the second air outlet 9 and the first air outlet 7 in the corresponding heat dissipation channel 5, thereby improving the heat dissipation efficiency; at the same time, when the first piston rod 11 drives the movable plate 8 to move, the movable plate 8 squeezes the second piston rod 15 to move. When the second piston rod 15 moves, it squeezes the inside of the second piston cylinder 14. The adjacent second piston cylinders 14 are connected through the second connecting pipe 16. When the inside of a group of second piston cylinders 14 is squeezed, the second piston cylinders 14 are connected. The hydraulic oil inside the plug cylinder 14 enters into the other second piston cylinders 14 through the second connecting pipe 16, and squeezes the inside of the other second piston cylinders 14, so that the second piston rod 15 inside the other second piston cylinders 14 moves, and the second piston rod 15 drives the moving plate 8 to move, so that the overlap effect of the second air outlet 9 on the other moving plate 8 and the first air outlet 7 is reduced, and the air outlet of other heat dissipation channels 5 is reduced, which is convenient for quickly dissipating heat in a group of heat dissipation channels 5 with higher temperatures, so that the heat dissipation efficiency in the corresponding heat dissipation channel 5 can be automatically adjusted according to the actual temperature change in the heat dissipation channel 5;

[0083] When the temperatures of the heat dissipation channels 5 in the cabinet 1 are all increased, the temperature increase drives the first piston rods 11 to move. When the first piston rods 11 move, they drive the corresponding moving plates 8 to move. When the moving plates 8 move, they drive the corresponding second piston rods 15 to move, thereby squeezing the inside of the second piston cylinders 14. Since the adjacent second piston cylinders 14 are connected through the second connecting pipes 16, the hydraulic oil in the second piston cylinders 14 is transported to the fixed cylinder 31 by the liquid outlet joint 37, the pipeline 38, and the liquid inlet joint 39, and the fixed cylinder 31 is squeezed, and the sealing is driven at the same time. When the plate 32 moves, the sealing plate 32 is separated from the magnet 35 and no longer adsorbed, and at the same time, the reset spring 36 is driven to move and store force. When the sealing plate 32 moves, the cross bar 33 is driven to move synchronously. When the cross bar 33 moves, the connecting plate 34 is driven to move. When the connecting plate 34 moves, the moving rod 26 is driven to move by the action of the card slot. When the moving rod 26 moves to a certain position, the second bevel gear 30 at one end of the moving rod 26 is meshed with the first bevel gear 29 for transmission, thereby driving the second blade 23 to rotate, thereby improving the heat dissipation efficiency inside the cabinet 1, further improving the use safety, and facilitating the automatic adjustment of the heat dissipation efficiency according to the actual temperature change inside the cabinet 1.

[0084] When the temperature inside the cabinet 1 drops, the squeezing force of the thermal expansion fluid on the first piston rod 11 decreases, thereby reducing the pressure on the hydraulic oil in the second piston cylinder 14. At this time, the sealing plate 32 is reset and moved by relying on the reset effect of the reset spring 36. After the sealing plate 32 is reset and moved to this state, the sealing plate 32 and the magnet 35 are magnetically adsorbed again, and at the same time, relying on the reset movement of the sealing plate 32, the hydraulic oil in the fixed cylinder 31 is transported to the second piston cylinder 14 through the pipeline 38; relying on the hydraulic oil squeezing the second piston cylinder 14 to drive the second piston rod 15 to move, and relying on the cooperation of the first piston rod 11 and the second piston rod 15 to drive the movable plate 8 to move, so that the movable plate 8 is moved to the corresponding position, thereby further improving the convenience of use.
