Description

Technical Field

[0001] This utility model relates to the field of transformer filter technology, specifically a detachable transformer filter that is easy to clean. Background Technology

[0002] Transformers generate heat during operation and require good ventilation to ensure stable operation. To prevent dust, impurities, and other contaminants from entering the transformer and affecting its insulation performance, hindering heat dissipation, or even causing malfunctions, filters are usually installed at the transformer's ventilation openings. These filters protect the heat sinks from dust and debris.

[0003] A related technology (announcement number: CN214068504U) discloses a transformer radiator filter screen. The disclosed technical solution is as follows: through the coordinated arrangement of a dual-head motor, a rotating rod, a drive wheel, and a transmission belt, the rotating rod and the bearing are kept on the same horizontal line, so that the dual-head motor can maximize energy transfer when rotating, avoiding energy loss. At the same time, through belt drive, the horizontal plate can be moved up and down. During the movement, dust and impurities on the filter screen can be cleaned, preventing radiator blockage and affecting its heat dissipation effect.

[0004] The following problems were found in the relevant technology: When cleaning the transformer filter, in order to ensure the cleaning effect, it is necessary to clean every part of the filter to ensure the filtration effect. Conventional filters are of fixed length and are installed directly according to the installation position. If they are too long, they need to be cut; if they are too short, they need to be spliced ​​again. In response, we have proposed a new type of detachable transformer filter that is easy to clean dust.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of disassembling and cleaning transformer filters in the prior art, this utility model provides a detachable transformer filter that facilitates dust cleaning. It employs a stretchable filter structure combined with a length adjustment structure to achieve the effect of easy dust cleaning. The specific technical solution is as follows:

[0007] A detachable transformer filter screen for easy dust cleaning includes a support frame. The outer wall of the support frame has a semi-open slot cavity. A winding post is embedded in the inner cavity of the semi-open slot cavity, and a semi-annular gap is formed between the inner wall of the semi-open slot cavity and the winding post. A filter screen passing through the semi-annular gap is arranged around the outer wall of the winding post. A base is fixed to the top of the support frame, and two bases are connected by an adjustable spacing member. Side posts that are slidably arranged on the base are fixed to both sides of the filter screen.

[0008] In the above technical solution, the adjusting component includes a fixed frame fixed to the opposite surfaces of the two bases. The fixed frame has a first connecting frame and a second connecting frame rotatably arranged inside. A bidirectional lead screw is arranged between the two fixed frames. The outer wall of the bidirectional lead screw is symmetrically threaded with a movable seat. The adjacent ends of the two first connecting frames and the two second connecting frames are symmetrically rotatably arranged on the two movable seats.

[0009] The bottom of the support frame is fixedly connected to a linkage base, and an inner support seat is provided between the two linkage bases. The two linkage bases are symmetrically sleeved on both sides of the inner support seat.

[0010] Both the linkage base and the outer wall of the base are provided with sliding grooves, and both ends of the side column are fixedly connected to positioning seats, and the outer wall of the positioning seats is fixedly connected to a slider that is slidably disposed on the inner wall of the sliding groove.

[0011] Each positioning seat located on the same side column is fixedly connected to a locking seat that is respectively attached to the linkage base and the side wall of the base, and the locking seat is threaded with a locking element.

[0012] Both the base and the linkage base are fixedly connected with connecting lugs.

[0013] The two sets of connecting ears are fixed in a stepped manner to the side walls of the base and the linkage base, respectively.

[0014] The filter screen is made of a soft material.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the detachable transformer filter screen that is easy to clean dust:

[0016] 1. When installing the filter, adjust the distance between the two bases according to the length of the transformer heat sink using the adjustable component. As the distance between the two support frames increases, the width of the filter stretches out. Then, pull the two side posts relative to each other and lock the position of the side posts. Finally, fix it to the transformer using the connecting lugs. This allows the filter to be adapted to transformer heat sinks of different lengths without the need for secondary cutting, thus facilitating the disassembly and assembly process for relevant personnel.

[0017] Second, when cleaning the filter screen, the distance between the two support frames is changed by the variable pitch component, so that the filter screen part located inside the support frame can be cleaned. By adjusting the position, each part of the filter screen can be cleaned, thereby ensuring the cleaning effect of the filter screen.

[0018] Third, the two linkage bases will move along with the two support frames. By synchronously supporting both ends of the side columns, the shape of the filter screen is prevented from being distorted, thus ensuring the stability of the filter screen adjustment and adaptation process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The following are specific implementation cases and appendices. Figure 1-3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0025] A detachable transformer filter for easy dust cleaning includes a support frame 1, the outer wall of which has a semi-open cavity 2. Two cylindrical support frames 1 each have a semi-open cavity 2 on their opposing outer walls, making the opposing surfaces of the two support frames 1 open structures, with the semi-circular edges forming a semi-open cavity 2. The upper and lower ends of a spiral post 3 are fixed to the upper and lower inner walls of the semi-open cavity 2, respectively. The spiral post 3 is embedded in the inner cavity of the semi-open cavity 2, and a semi-annular gap is formed between the inner wall of the semi-open cavity 2 and the spiral post 3. A filter 4, passing through the semi-annular gap, is arranged around the outer wall of the spiral post 3.

[0026] Since the winding column 3 is fixed at the center of the semi-slotted cavity 2, an arc-shaped slide is formed between the winding column 3 and the inner wall of the semi-slotted cavity 2. The filter screen 4 is laid flat between the two support frames 1, and the edges of the left and right sides of the filter screen 4 are located on the back side of the filter screen 4 after passing through the semi-circular gaps on both sides. The filter screen 4 slides against the inner wall of the arc-shaped slide.

[0027] A base 6 is fixed to the top of the support frame 1, and the two bases 6 are connected by an adjustable spacing component. Side posts 5 are fixed to both sides of the filter screen 4 and slidably mounted on the base 6. The side posts 5 are fixed at both sides of the filter screen 4, and the two ends of the side posts 5 slide against the outer wall of the base 6.

[0028] When installing filter 4, the distance between the two bases 6 is adjusted according to the length of the transformer heat sink using the adjusting component, so that the two support frames 1 are located on both sides of the transformer heat sink. As the distance between the two support frames 1 increases, the width of filter 4 stretches out, allowing filter 4 to slide around the rotating post 3. When the distance adjustment is appropriate, the two side posts 5 are pulled relative to each other, and then the position of the side posts 5 is locked. Subsequently, it is fixed to the transformer through the connecting lug 17, so that filter 4 can be adapted to transformer heat sinks of different lengths without secondary cutting, thus bringing convenience to the disassembly and assembly process of relevant personnel.

[0029] When cleaning the filter screen 4, the distance between the two support frames 1 is changed by the variable pitch component, so that the part of the filter screen 4 located inside the support frame 1 can be cleaned. By adjusting the position, each part of the filter screen 4 can be cleaned, thereby ensuring the cleaning effect of the filter screen 4.

[0030] The adjustable component includes a fixed frame 9 fixed to the opposite faces of two bases 6. A first connecting frame 11 and a second connecting frame 12 are rotatably mounted inside the fixed frame 9. A bidirectional lead screw 10 is positioned between the two fixed frames 9. A movable seat 13 is symmetrically threaded onto the outer wall of the bidirectional lead screw 10. The adjacent ends of the two first connecting frames 11 and the two second connecting frames 12 are symmetrically rotatably mounted on the two movable seats 13. After adjusting the length of the filter screen 4 according to the transformer heat sink, the exposed components are protected by a protective cover.

[0031] Two fixed brackets 9 are respectively fixed to the opposite faces of two bases 6. Two parallel shafts are installed on the inner wall of each fixed bracket 9. One end of the first connecting bracket 11 and the second connecting bracket 12 are movably sleeved on the outside of the two shafts through the openings. Shafts are installed on the outer wall of each movable seat 13. The other ends of the first connecting bracket 11 and the second connecting bracket 12 are movably sleeved on the outside of the shafts of the movable seat 13 through the openings. This makes the two ends of the two hinged first connecting brackets 11 and the two hinged second connecting brackets 12 respectively hinged to the opposite faces of the two bases 6. The hinge points of the two first connecting brackets 11 and the two second connecting brackets 12 are all located on the two movable seats 13. The outer wall of the bidirectional lead screw 10 has two parts of external threads with opposite threads and the same pitch from the center to both sides. The two movable seats 13 are connected to the bidirectional lead screw 10 through two threaded through holes.

[0032] When adjusting the distance between the two support frames 1, the double-acting screw 10 is turned so that the two moving seats 13 move relative to each other or back to back, thereby causing the hinge joints of the two first connecting frames 11 and the two second connecting frames 12 to fold and change, thereby adjusting the distance between the two support frames 1.

[0033] It is worth noting that a linkage base 7 is fixedly connected to the bottom of the support frame 1, and an inner support seat 8 is provided between the two linkage bases 7. The two linkage bases 7 are symmetrically fitted onto both sides of the inner support seat 8. Through holes are opened on the opposite surfaces of the two linkage bases 7, allowing the two linkage bases 7 to slide against the outer wall of the inner support seat 8 respectively. This allows the two linkage bases 7 to move with the two support frames 1, and by synchronously supporting both ends of the side post 5, the shape of the filter screen 4 is prevented from twisting, thereby ensuring the stability of the filter screen 4 during the adjustment and adaptation process.

[0034] Furthermore, both the outer walls of the linkage base 7 and the base 6 are provided with sliding grooves 16, and both ends of the side column 5 are fixedly connected to positioning seats 14, with sliders 18 slidably disposed on the inner wall of the sliding groove 16 fixedly connected to the outer wall of the positioning seats 14. Sliding grooves 16 with a T-shaped cross-section are provided on the outer walls of both the linkage base 7 and the base 6, and sliders 18 with a T-shaped cross-section are fixedly installed at both the upper and lower ends of the side column 5, allowing the sliders 18 to slide against the inner wall of the sliding groove 16. The sliding cooperation between the sliders 18 and the sliding groove 16 ensures the stability of the side column 5 as it moves with the filter screen 4.

[0035] In addition, each positioning seat 14 located on the same side post 5 is fixedly connected to a locking seat 15 that is respectively attached to the side wall of the linkage base 7 and the base 6, and a locking element is threaded onto the locking seat 15. The locking element can be a bolt, which passes through the locking seat 15 and is snapped into the surface of the base 6. By fixing both ends of the side post 5 to the surfaces of the base 6 and the linkage base 7 respectively, the stability of the filter screen 4 after installation is ensured.

[0036] Furthermore, both the base 6 and the linkage base 7 are fixedly connected with connecting ears 17.

[0037] Two sets of connecting ears 17 are fixed in a stepped manner to the side walls of the base 6 and the linkage base 7 respectively. The two connecting ears 17 are located at the top of the base 6 with one higher and one lower, and two connecting ears 17 with one higher and one lower are fixedly installed at the bottom of the linkage base 7. The two connecting ears 17 are selected according to the installation position, and the connecting ears 17 in the appropriate position are connected to the transformer.

[0038] The filter screen 4 is made of a soft material. The soft material filter screen 4 can be made of aluminum, which allows the filter screen 4 to slide around the post 3 without causing damage to the filter screen 4.
