Description

Technical Field

[0001] This utility model relates to the technical field of capacitor protection devices, specifically a protection device for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors are a common type of electrolytic capacitor. Their anode (positive electrode) uses high-purity aluminum foil, and a very thin layer of aluminum oxide is formed on the surface through an electrochemical method as a dielectric layer. The cathode (negative electrode) is usually a liquid or solid electrolyte. The traditional packaging method for aluminum electrolytic capacitors is to directly put medium and high voltage aluminum electrolytic capacitors into plastic sealed bags for sealing. During transportation or storage, if the packaging bag is squeezed, it is very easy to cause the lead wires of medium and high voltage aluminum electrolytic capacitors to break or the capacitor to be damaged, resulting in unnecessary losses.

[0003] As disclosed in the authorization announcement number CN208453468U, a protective device for medium and high voltage aluminum electrolytic capacitors includes a housing, limiting blocks, movable plates, limiting posts, screws, knobs, fixing plates, a housing cover, and foam pads. Grooves are symmetrically arranged on the left and right sides of the inner wall of the housing. Limiting blocks are arranged below the grooves on both sides. The limiting blocks are fixed to the inner wall of the housing. A movable plate is arranged above the limiting blocks. Limiting holes are evenly arranged on the movable plate. Movable blocks are symmetrically arranged in the middle of the left and right sides of the movable plate. Each movable block is provided with an internal threaded through hole. The movable blocks are located inside the grooves. Screws are rotatably connected to the bottom of each groove.

[0004] It can avoid damage to medium and high voltage aluminum electrolytic capacitors due to compression during storage or transportation, and it is also convenient for users to handle, making it highly applicable.

[0005] However, this does not solve the problem that existing capacitor protection devices are generally not convenient for convenient layered storage during use. It increases the storage range, facilitates convenient protection of capacitors, sets up a separate conical rack, and avoids the situation of compression during the storage of capacitor protection devices, thereby improving the protective effect of capacitor protection devices on capacitors. Utility Model Content

[0006] The purpose of this utility model is to provide a protective device for aluminum electrolytic capacitors, so as to solve the problems mentioned in the background art, which are that capacitor protective devices are not convenient for convenient layered storage, which affects the storage range, are not convenient for convenient protection of capacitors, and are prone to compression during storage, thus affecting the protective effect of capacitor protective devices on capacitors.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A protective device for aluminum electrolytic capacitors includes a housing and a top cover. The top cover is provided on the outside of the housing. A first sealing ring is installed on the top of the housing, and a second sealing ring is installed on the bottom of the top cover. Rotating shafts are movably installed on both sides of the housing. Electric push rods are movably installed on the surface of each rotating shaft. Support shafts are movably installed on the output ends of each electric push rod. Each electric push rod is movably connected to the top cover through the support shaft. Rotating shafts are movably installed on the side walls of the housing. The housing is movably connected to the top cover through the rotating shafts. A lifting plate is provided inside the housing.

[0009] Optionally, a first storage plate is installed at the top of the lifting plate, and a second storage plate is provided outside the first storage plate.

[0010] Optionally, a third storage plate is provided on the outside of the second storage plate, and the surfaces of the first storage plate, the second storage plate, and the circular through hole are all provided with multiple sets of circular through holes at equal intervals.

[0011] Optionally, servo motors are symmetrically installed inside the housing, and threaded rods are installed at the output ends of the servo motors. Support seats are symmetrically installed on the top side wall of the housing.

[0012] Optionally, all the threaded rods extend into the interior of the support and are movably connected thereto, and the surfaces of all the threaded rods are fitted with threaded blocks.

[0013] Optionally, all the threaded rods are threadedly connected to the threaded blocks, all the threaded blocks are connected to the lifting plate, and all the circular through holes are movably mounted with a tapered frame body.

[0014] Optionally, the top ends of the first storage plate and the second storage plate are symmetrically provided with grooves, and the bottom ends of the second storage plate and the third storage plate are symmetrically provided with support plates, which cooperate with the grooves.

[0015] Optionally, the surface of the conical frame body is provided with a second through hole, and the surface of the conical frame body above the second through hole is provided with a first through hole. A first plastic elastic sheet is elastically placed inside the conical frame body, and the first plastic elastic sheet extends through the second through hole to its outside.

[0016] Optionally, an aluminum electrolytic capacitor body is provided at the top end of the first plastic elastic sheet, and a second plastic elastic sheet is provided at the top end of the aluminum electrolytic capacitor body.

[0017] Optionally, the second plastic elastic sheet extends through the first through hole to its outside, and both the first and second plastic elastic sheets are elastically connected to the second through hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the capacitor protection device not only realizes convenient layered storage of capacitor protection devices, increases the storage range, facilitates convenient protection of capacitors, and sets up a separate conical rack, but also avoids the situation of compression during the storage of capacitor protection devices, thereby improving the effect of capacitor protection devices in protecting capacitors.

[0019] An electric push rod drives the support shaft to move, causing the top cover and the second sealing ring to rotate around the rotation shaft. This creates an angle between the top cover and the housing, disengaging the second sealing ring from the first sealing ring. Aluminum electrolytic capacitor bodies are then placed sequentially within the conical frame on the surface of the first storage plate. When the first storage plate is full, a second storage plate is manually placed on top. Two sets of support plates at the bottom of the second storage plate engage with two sets of grooves on the surface of the first storage plate, providing limiting support and allowing more aluminum electrolytic capacitor bodies to be placed on its surface. When the second storage plate is full, a third storage plate is stacked on top. After placement, the electric push rod is reversed, causing it to drive the support shaft to move in the opposite direction. This causes the top cover and the second sealing ring to rotate in the opposite direction around the rotation shaft, bringing the top cover closer to the housing and bringing the second sealing ring into contact with the first sealing ring. This allows for convenient layered storage of the capacitor protection device, increasing the storage capacity.

[0020] Two sets of electric push rods drive the support shaft to move, and the support shaft drives the top cover to rotate to one side around the rotating shaft. The servo motor drives the threaded rod to rotate, and the threaded rod drives two sets of threaded blocks to move upward. The threaded blocks drive the lifting plate to move upward, and the lifting plate drives the first storage plate, the second storage plate, the third storage plate, the conical frame body, and the aluminum electrolytic capacitor body to move upward to the outside of the box. Under the elastic deformation of the first and second plastic elastic sheets, multiple sets of first plastic elastic sheets are placed sequentially on the surface of the second through hole for limiting support, and multiple sets of aluminum electrolytic capacitor bodies are placed sequentially on the surface of the first plastic elastic sheets. The second plastic elastic sheets are placed sequentially on the surface of the first through hole for limiting support, thus protecting the aluminum electrolytic capacitor bodies. This achieves convenient protection of the capacitors with the capacitor protection device. The separate conical frame avoids the situation of compression during the storage of the capacitor protection device, improving the protection effect of the capacitor protection device on the capacitors.

[0036] like Figures 1 to 6As shown, an embodiment of this utility model provides a protective device for aluminum electrolytic capacitors, including a housing 1 and a top cover 2. The top cover 2 is provided on the outside of the housing 1. A first sealing ring 3 is installed on the top of the housing 1, and a second sealing ring 4 is installed on the bottom of the top cover 2. Rotating shafts 5 are movably installed on both sides of the housing 1. Electric push rods 6 are movably installed on the surface of the rotating shafts 5. Support shafts 7 are movably installed on the output ends of the electric push rods 6. The electric push rods 6 are movably connected to the top cover 2 through the support shafts 7. Rotating shafts 8 are movably installed on the side walls of the housing 1. The housing 1 is movably connected to the top cover 2 through the rotating shafts 8. A lifting plate 13 is provided inside the housing 1. A first storage plate 14 is installed on the top of the lifting plate 13. A second storage plate 15 is provided on the outside of the first storage plate 14. A third storage plate 16 is provided on the outside of the second storage plate 15. Multiple sets of circular through holes 17 with equal spacing are provided on the surfaces of the first storage plate 14, the second storage plate 15, and the circular through holes 17.

[0037] When using the aluminum electrolytic capacitor protection device, open the two sets of electric push rods 6. Under the movable support of the rotating shaft 5, the electric push rods 6 drive the support shaft 7 to move. Under the limiting support of the rotating shaft 8, the support shaft 7 drives the top cover 2 and the second sealing ring 4 to rotate around the rotating shaft 8, so that the top cover 2 forms a certain angle with the box body 1, thereby causing the second sealing ring 4 to separate from the first sealing ring 3. Place the aluminum electrolytic capacitor body 25 in the conical frame body 20 on the surface of the first storage plate 14. When the surface of the first storage plate 14 is full, manually place the second storage plate 15 on top of the first storage plate 14. The two sets of support plates 19 at the bottom of the second storage plate 15 are then placed on top of the first storage plate 14. The two sets of grooves 18 on the surface of the first storage plate 14 cooperate to limit and support the second storage plate 15, so that the aluminum electrolytic capacitor body 25 can be placed on the surface of the second storage plate 15. When the surface of the second storage plate 15 is full, the third storage plate 16 is stacked on top for storage. After the placement is completed, the electric push rod 6 is opened in the reverse direction, so that the electric push rod 6 drives the support shaft 7 to move in the reverse direction. The support shaft 7 drives the top cover 2 and the second sealing ring 4 to rotate in the reverse direction around the rotating shaft 8, so that the top cover 2 moves closer to the box 1, so that the second sealing ring 4 contacts the first sealing ring 3. This realizes convenient layered storage of capacitor protection devices and increases the storage range.

[0038] Servo motors 9 are symmetrically installed inside the housing 1. Each output end of the servo motor 9 is equipped with a threaded rod 10. Support seats 12 are symmetrically installed on the top side wall of the housing 1.

[0039] All threaded rods 10 extend into the interior of the support base 12 and are movably connected thereto. All threaded rods 10 are fitted with threaded blocks 11, and all threaded rods 10 are threadedly connected to the threaded blocks 11. All threaded blocks 11 are connected to the lifting plate 13. All circular through holes 17 are movably mounted with tapered frame bodies 20.

[0040] The top of the first storage plate 14 and the second storage plate 15 are symmetrically provided with grooves 18, and the bottom of the second storage plate 15 and the third storage plate 16 are symmetrically provided with support plates 19, which cooperate with the grooves 18.

[0041] The surface of the tapered frame body 20 is provided with a second through hole 22, and the surface of the tapered frame body 20 above the second through hole 22 is provided with a first through hole 21. A first plastic elastic sheet 23 is elastically placed inside the tapered frame body 20, and the first plastic elastic sheet 23 extends through the second through hole 22 to its outside.

[0042] The top end of the first plastic elastic sheet 23 is provided with an aluminum electrolytic capacitor body 25, and the top end of the aluminum electrolytic capacitor body 25 is provided with a second plastic elastic sheet 24.

[0043] The second plastic elastic sheet 24 extends through the first through hole 21 to its outside, the first plastic elastic sheet 23 is elastically connected to the second through hole 22, and the second plastic elastic sheet 24 is elastically connected to the first through hole 21.

[0044] When the aluminum electrolytic capacitor body 25 needs to be loaded, the two sets of electric push rods 6 are opened, causing the two sets of electric push rods 6 to drive the support shaft 7 to move. The support shaft 7 drives the top cover 2 to rotate to one side around the rotating shaft 8. The two sets of servo motors 9 are opened. With the support of the housing 1, the servo motors 9 drive the threaded rod 10 to rotate. With the threaded connection between the threaded rod 10 and the threaded block 11, the threaded rod 10 drives the two sets of threaded blocks 11 to move upward. The threaded blocks 11 drive the lifting plate 13 to move upward. The lifting plate 13 drives the first storage plate 14, the second storage plate 15, the third storage plate 16, the conical frame body 20, and the aluminum electrolytic capacitor body 25 to move upward. To the outside of the housing 1, under the elastic deformation of the first plastic elastic sheet 23 and the second plastic elastic sheet 24, multiple sets of the first plastic elastic sheet 23 are sequentially placed on the surface of the second through hole 22 for limiting support, multiple sets of aluminum electrolytic capacitor bodies 25 are sequentially placed on the surface of the first plastic elastic sheet 23, and the second plastic elastic sheet 24 is sequentially placed on the surface of the first through hole 21 for limiting support, thus protecting the aluminum electrolytic capacitor bodies 25. This achieves convenient protection of the capacitors by the capacitor protection device. The separate conical frame avoids the situation of compression during the storage of the capacitor protection device, and improves the protection effect of the capacitor protection device on the capacitors.

[0045] The working principle of the technical solution provided by this utility model is as follows: When in use, the aluminum electrolytic capacitor protection device uses an electric push rod 6 to drive the support shaft 7 to move. Under the limiting support of the rotating shaft 8, the support shaft 7 drives the top cover 2 and the second sealing ring 4 to rotate around the rotating shaft 8, so that the top cover 2 and the box 1 form a certain angle, thereby causing the second sealing ring 4 to separate from the first sealing ring 3. The aluminum electrolytic capacitor body 25 is then placed sequentially into the conical frame body 20 on the surface of the first storage plate 14. When the surface of the first storage plate 14 is full, the second sealing ring 4 is manually placed into the box. Storage plate 15 is placed above first storage plate 14. Two sets of support plates 19 at the bottom of second storage plate 15 cooperate with two sets of grooves 18 on the surface of first storage plate 14 to limit and support second storage plate 15, so that aluminum electrolytic capacitor bodies 25 can be placed on the surface of second storage plate 15. When the surface of second storage plate 15 is full, third storage plate 16 is stacked on top for storage. After placement is completed, electric push rod 6 is opened in reverse, so that electric push rod 6 drives support shaft 7 to move in the opposite direction. Support shaft 7 drives top cover 2 and second storage plate 14 to move in the opposite direction. The sealing ring 4 rotates in the opposite direction around the rotating shaft 8, causing the top cover 2 to move closer to the housing 1, so that the second sealing ring 4 contacts the first sealing ring 3. The two sets of electric push rods 6 drive the support shaft 7 to move, and the support shaft 7 drives the top cover 2 to rotate to one side around the rotating shaft 8. The servo motor 9 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the two sets of threaded blocks 11 to move upward. The threaded blocks 11 drive the lifting plate 13 to move upward, and the lifting plate 13 drives the first storage plate 14, the second storage plate 15, the third storage plate 16, and the conical frame. The main body 20 and the aluminum electrolytic capacitor body 25 are moved upward to the outside of the housing 1. Under the elastic deformation of the first plastic elastic sheet 23 and the second plastic elastic sheet 24, multiple sets of the first plastic elastic sheet 23 are placed on the surface of the second through hole 22 for limiting support, multiple sets of aluminum electrolytic capacitor bodies 25 are placed on the surface of the first plastic elastic sheet 23, and the second plastic elastic sheet 24 is placed on the surface of the first through hole 21 for limiting support, thus protecting the aluminum electrolytic capacitor body 25 and completing the use of the capacitor protection device.
