Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to an intelligent monitoring aging equipment for aluminum electrolytic capacitors. Background Art

[0002] Capacitors are energy storage components used in circuits for tuning, filtering, coupling, bypassing, energy conversion, and delay. Capacitors are usually called capacitors. According to their structure, they can be divided into three types: fixed capacitors, semi-variable capacitors, and variable capacitors.

[0003] When electrolytic capacitors are used for a long time, aging will occur, among which bulging is particularly common. In a high temperature environment, the electrolyte in the electrolytic capacitor evaporates and loses water, which hinders its internal stability and thus causes bulging. Therefore, the use of electrolytic capacitors requires attention to the use method and the use environment. In the prior art, when electrolytic capacitors are used, they are usually monitored by performing regular inspections on them. This method consumes manpower and cannot detect aging electrolytic capacitors in the first place, which brings inconvenience to use. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent monitoring aging device for aluminum electrolytic capacitors, which can effectively solve the problem that when the electrolytic capacitors are used in the prior art, the electrolytic capacitors are usually monitored by regular inspections thereof, which is manpower-consuming and cannot detect the aging electrolytic capacitors in the first place.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides an intelligent monitoring aging device for aluminum electrolytic capacitors, comprising a mounting back plate, a mounting groove is provided on the mounting back plate, a reciprocating screw rod is rotatably connected in the mounting groove, a rotating motor for driving the reciprocating screw rod to rotate is fixedly installed on the inner side wall of the mounting groove, a slider is slidably provided through the rod body of the reciprocating screw rod, a monitoring device body is provided on the slider, a first active bevel gear is fixedly provided on the rod body of the reciprocating screw rod, and the first active bevel gear is symmetrically meshed with two first driven bevel gears, and the two first driven bevel gears are both connected to the mounting back plate. The inner wall of the groove is rotatably connected, and a plurality of grooves are provided on the mounting back plate, in which a second driven bevel gear is rotatably connected, and the second driven bevel gear is coaxially fixedly connected with a rotating rod, and the first driven bevel gear is coaxially fixedly connected with a rotating shaft, and the other end of the rotating shaft is coaxially fixedly connected with a second active bevel gear meshing with the second driven bevel gear, an installation frame is provided in the groove, and the rotating rod is provided through the installation frame, and a plurality of heat dissipation blades are fixedly provided in an annular manner on the rod body of the rotating rod, and a plurality of heat dissipation holes connected with the grooves are also provided on the mounting back plate.

[0006] According to the above-mentioned intelligent monitoring aging equipment for aluminum electrolytic capacitors, an equipment slot is provided on the slider, and two arc-shaped limit blocks are symmetrically slidably arranged in the equipment slot, and a plurality of limit springs are fixedly connected between the arc-shaped limit blocks and the equipment slot.

[0008] According to the above-mentioned intelligent monitoring aging equipment for aluminum electrolytic capacitors, protective pads are fixedly bonded to opposite ends of the two arc-shaped limit blocks, and the protective pads are made of elastic material.

[0009] According to the above-mentioned intelligent monitoring aging equipment for aluminum electrolytic capacitors, a temperature sensor is also fixedly embedded and installed on the slider.

[0010] According to the above-mentioned intelligent monitoring and aging equipment for aluminum electrolytic capacitors, the temperature sensor signal is connected to a controller, and the controller is electrically connected to the rotating motor.

[0011] According to the above-mentioned intelligent monitoring and aging equipment for aluminum electrolytic capacitors, a limiting column is fixedly arranged in the installation groove, and the limiting column is slidably penetrated and connected with the sliding block.

[0012] According to the above-mentioned intelligent monitoring aging equipment for aluminum electrolytic capacitors, a connecting groove is opened between the multiple grooves on the same side of the installation groove, the rod bodies of the multiple rotating rods are fixedly sleeved with sprockets, and the outer sides of the multiple sprockets are commonly sleeved with chains.

[0013] According to the above-mentioned intelligent monitoring and aging equipment for aluminum electrolytic capacitors, the diameter of the first active bevel gear is greater than the diameter of the first driven bevel gear, and the diameter of the second active bevel gear is greater than the diameter of the second driven bevel gear.

[0014] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The working environment temperature of the aluminum electrolytic capacitor is monitored in real time through the temperature sensor.

On the other hand, the diameters of the first active bevel gear and the second active bevel gear are respectively larger than the diameters of the first driven bevel gear and the second driven bevel gear, which accelerates the rotating rod, ensures clear shooting of the monitoring device body, and ensures that the rotating rod drives the heat dissipation fan blades to rotate and dissipate heat, which is easy to use.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] Example: Refer to Figures 1 to 4 An intelligent monitoring aging device for aluminum electrolytic capacitors includes a mounting back plate 1. The mounting back plate 1 is installed in the environment where the aluminum electrolytic capacitors are used. The aluminum electrolytic capacitors can be protected and monitored by a monitoring device body 11 installed on the mounting back plate 1.

[0023] An installation groove 2 is provided on the installation back plate 1, and a reciprocating screw rod 3 is rotatably connected in the installation groove 2. A rotating motor 4 for driving the reciprocating screw rod 3 to rotate is also fixedly installed on the inner side wall of the installation groove 2. A slider 5 is slidably penetrated through the rod body of the reciprocating screw rod 3, and a temperature sensor 12 is also fixedly embedded and installed on the slider 5. By setting the temperature sensor 12, the working environment temperature of the aluminum electrolytic capacitor can be monitored in real time.

[0024] A limiting column 13 is fixedly arranged in the installation groove 2 , and the limiting column 13 is slidably connected with the slider 5 . By setting the limiting column 13 , it is ensured that the rotation of the reciprocating screw 3 can drive the slider 5 to slide horizontally on the rod body of the reciprocating screw 3 .

[0025] The temperature sensor 12 is signal-connected to a controller, and the controller is electrically connected to the rotating motor 4 . When the temperature sensor 12 detects that the working environment of the aluminum electrolytic capacitor is in a high temperature state, the controller controls the rotating motor 4 to start.

[0026] A monitoring device body 11 is arranged on the slider 5, and a device slot 6 is opened on the slider 5. Two arc-shaped limit blocks 8 are symmetrically and slidably arranged in the device slot 6. A plurality of limit springs 7 are fixedly connected between the arc-shaped limit blocks 8 and the device slot 6. When the monitoring device body 11 is inspected and repaired, the two arc-shaped limit blocks 8 are pulled in opposite directions, and the plurality of limit springs 7 are further compressed. By increasing the spacing between the two arc-shaped limit blocks 8, it is convenient to remove the monitoring device body 11 from between the two arc-shaped limit blocks 8, so as to facilitate the inspection and replacement of the monitoring device body 11.

[0027] The slider 5 is provided with a plurality of guide grooves 10 connected with the equipment groove 6. The opposite ends of each arc-shaped limit block 8 of the chain are fixedly connected with a plurality of guide rods 9 slidably connected with the guide grooves 10. By setting the guide rods 9 to slide in cooperation with the guide grooves 10, the movement of the arc-shaped limit block 8 can be guided. In addition, each limit spring 7 is arranged on the outer side of the corresponding guide rod 9, which can effectively avoid elastic deformation of the limit spring 7 and increase the service life of the limit spring 7.

[0028] The two arc-shaped limit blocks 8 are fixedly bonded with protective pads at opposite ends, and the protective pads are made of elastic material. When limiting, the protective pads are in elastic contact with the monitoring device body 11, so as to protect the monitoring device body 11. On the other hand, by increasing the static friction between the two, the limiting effect on the monitoring device body 11 can be increased.

[0029] The shaft of the reciprocating screw rod 3 is fixedly sleeved with a first active bevel gear 14, and the first active bevel gear 14 is symmetrically meshed with two first driven bevel gears 15, the diameter of the first active bevel gear 14 is larger than the diameter of the first driven bevel gear 15, and because the diameter of the first active bevel gear 14 is larger than the diameter of the first driven bevel gear 15, when the reciprocating screw rod 3 rotates to drive the first active bevel gear 14 to rotate, one rotation of the first active bevel gear 14 can electrically drive the first driven bevel gear 15 to rotate multiple times, thereby achieving an acceleration effect.

[0030] The two first driven bevel gears 15 are both rotatably connected to the inner wall of the mounting groove 2. A plurality of grooves 16 are provided on the mounting back plate 1. A second driven bevel gear 17 is rotatably connected in the groove 16. The second driven bevel gear 17 is coaxially fixedly connected to a rotating rod 20. A connecting groove 21 is provided between the plurality of grooves 16 on the same side of the mounting groove 2. The rod bodies of the plurality of rotating rods 20 are all fixedly sleeved with sprockets 22. Chains 23 are commonly sleeved on the outer sides of the plurality of sprockets 22. By providing a plurality of sprockets 22 and chains 23, a single driving source can be used to drive the plurality of rotating rods 20 to rotate, thereby saving equipment costs.

[0031] The first driven bevel gear 15 is coaxially fixedly connected with a rotating shaft 19, and the other end of the rotating shaft 19 is coaxially fixedly connected with a second driving bevel gear 18 meshing with the second driven bevel gear 17. The diameter of the second driving bevel gear 18 is larger than the diameter of the second driven bevel gear 17. The second driving bevel gear 18 is connected to the first driven bevel gear 15, so the number of circles of the second driving bevel gear 18 is the same as that of the first driven bevel gear 15. The first driving bevel gear 14 is meshed with the first driven bevel gear 15, which has an acceleration effect on the first driven bevel gear 15. Similarly, the second driving bevel gear 18 is meshed with the second driven bevel gear 17, which has an acceleration effect on the second driven bevel gear 17, so that the rotation speed of the rotating rod 20 is accelerated.

[0032] An installation frame 25 is provided in the groove 16, and the rotating rod 20 is arranged through the installation frame 25. A plurality of heat dissipation blades 26 are fixedly provided in a ring shape on the rod body of the rotating rod 20. A plurality of heat dissipation holes 24 connected to the groove 16 are also provided on the mounting back plate 1. The rotation of the rotating rod 20 drives the heat dissipation blades 26 distributed on the outside of the rotating rod 20 to rotate and dissipate heat, thereby ensuring the working environment of the aluminum electrolytic capacitor.

[0033] The specific working steps of the present invention are as follows: When in use, the mounting back plate 1 is mounted in the environment where the aluminum electrolytic capacitor is used, and the working environment temperature of the aluminum electrolytic capacitor is monitored in real time through the temperature sensor 12. When the working environment temperature of the aluminum electrolytic capacitor is high, when the temperature sensor 12 detects that the working environment of the aluminum electrolytic capacitor is in a high temperature state, the controller controls the rotating motor 4 to start, and the rotating motor 4 drives the reciprocating screw rod 3. On the one hand, under the limit of the limit column 13, the slider 5 is driven to slide back and forth on the rod body of the reciprocating screw rod 3, and the monitoring device body 11 installed on the slider 5 is driven to move while monitoring the aluminum electrolytic capacitor. Through the monitoring of the aluminum electrolytic capacitor by the monitoring device body 11, it is checked whether the aluminum electrolytic capacitor has aging bulges. Problems such as these are solved to find the cause of the high temperature problem. On the other hand, the reciprocating screw 3 rotates, driving the first active bevel gear 14 to engage with the first driven bevel gear 15, and connecting the second active bevel gear 18 to the first driven bevel gear 15 through the rotating shaft 19, driving the second active bevel gear 18 to engage with the second driven bevel gear 17, and driving the rotating rod 20 to rotate. The multiple sprockets 22 and chains 23 are provided to drive the multiple rotating rods 20 to rotate together, and drive the heat dissipation fan blades 26 distributed on the outside of the rotating rod 20 to rotate and dissipate heat, thereby ensuring the working environment of the aluminum electrolytic capacitor. Not only can the aluminum electrolytic capacitor itself be detected and monitored as soon as possible when the temperature is abnormal, but the working environment of the aluminum electrolytic capacitor can also be cooled.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
