These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0036] It should be noted that in the description of the embodiments of the present application, the terms "upper", "lower", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the embodiments of the present application. First, the relevant concepts or terms involved in this application are explained:

[0037] Foreign matter: refers to debris attached to the transformer heat sink, such as branches, bird nests, plastic bags and other objects with a certain volume that will affect the heat sink capacity of the transformer; attachment can mean that these debris completely covers or partially covers the transformer heat sink, or it can mean that these debris are inserted or stuck on the transformer heat sink or in the gap between it and the transformer body.

[0038] Transformers are crucial components in power systems and are often installed outdoors, such as in mountainous areas, near bird habitats, and in bushes. Transformer heat sinks are crucial for dissipating heat from the transformer and are typically located on the transformer's casing. For example, they can be installed on the bottom, sides, and top of the transformer.

[0039] When transformer heat sinks are mounted on the top or side of the transformer, dead branches and leaves, or windblown foreign objects like plastic bags, can fall onto or become lodged in the heat sinks. Furthermore, because the area near the heat sinks is relatively warm and dry, some birds build sturdy nests there. Foreign objects clinging to the heat sinks can affect the transformer's heat dissipation and, in severe cases, could even cause a fire, necessitating regular cleaning.

[0040] In the prior art, a longer insulating rod is often used, with smooth ends. One end of the insulating rod is brought into contact with the foreign matter attached to the transformer heat sink, and the insulating rod is moved up and down to remove the attached foreign matter. However, in some cases, the attached foreign matter is not easy to separate from the transformer heat sink, such as a bird's nest that is firmly connected to the transformer heat sink. It is necessary to repeatedly move the insulating rod several times to remove the bird's nest, which is inconvenient to clean. Moreover, in the process of moving the insulating rod up and down, the bird's nest may drop some large pieces of debris due to the strong shaking, which affects the field of vision and makes cleaning more inconvenient. In addition, when a foreign matter is stuck in the gap between the transformer heat sink, where it is difficult to apply force with the insulating rod, the insulating rod is difficult to align with the foreign matter. It is necessary to repeatedly move the insulating rod several times to remove the foreign matter, which is inconvenient to clean. For example, some foreign matter, such as leaves on the transformer heat sink, is stuck in the gap. Moving the insulating rod will move the foreign matter deeper into the gap.

[0041] Based on this, the present application provides a tool for cleaning foreign matter in a transformer heat sink, comprising a clamping assembly and a connecting rod assembly; the clamping assembly comprises a first clamping member and a second clamping member, the first clamping member being hinged to the second clamping member; the connecting rod assembly comprises a rod body and a movable member, the rod body having a mounting cavity, the movable member being inserted into the mounting cavity, and the second clamping member being disposed on the rod body; the movable member comprising a movable rod and a driving member disposed on the movable rod, the driving member being slidably connected to the first clamping member. The first clamping member and the second clamping member jointly clamp the foreign matter, and the movable rod is pushed to move along the extension direction of the mounting cavity, so that the driving member drives the first clamping member to approach the second clamping member, thereby clamping the foreign matter. After clamping the foreign matter, the rod body is moved to clamp the foreign matter out of the transformer heat sink. Since the foreign matter is clamped, the rod body is moved again, so that the foreign matter can be separated from the transformer heat sink in different directions, thereby facilitating the cleaning of foreign matter on the transformer heat sink. The tool for cleaning foreign matter in a transformer heat sink of the present application is convenient for cleaning foreign matter on the transformer heat sink.

[0042] The following combination Figures 1 to 4 The present application is described with specific examples.

[0043] Figure 1 A schematic diagram of the structure of a tool for cleaning foreign matter from a transformer heat sink provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the structure of the middle mounting cavity and the clamping assembly; Figure 3 for Figure 1 Schematic diagram of the structure outside the middle rod body; Figure 4 for Figure 1 Schematic diagram of the structure of the sliding groove on the middle drive member.

[0044] It should be noted that Figure 1 The horizontal arrow indicates the moving direction of the movable rod 223 when the first clamping member 110 approaches the second clamping member 120 . Figure 1 The rotation arrow on the middle rotation rod 111 indicates the rotation direction of the rotation rod 111 when the first clamping member 110 approaches the second clamping member 120 . Figure 1 The rotation arrow on the right side of the middle clamping member 113 indicates the rotation direction of the clamping member 113 when the first clamping member 110 approaches the second clamping member 120 .

[0045] Combine Figures 1 to 4 The tool for cleaning foreign objects in the heat sink of a transformer provided in the present application includes: a clamping assembly 100 and a connecting rod assembly 200; the clamping assembly 100 includes a first clamping member 110 and a second clamping member 120, and the first clamping member 110 is hinged to the second clamping member 120; the connecting rod assembly 200 includes a rod body 210 and a movable member 220, the rod body 210 has an installation cavity 211, the movable member 220 is inserted in the installation cavity 211, and the second clamping member 120 is arranged on the rod body 210; the movable member 220 includes a movable rod 223 and a driving member 221 arranged on the movable rod 223, and the driving member 221 is slidably connected to the first clamping member 110; the movable rod 223 moves along the extension direction of the installation cavity 211, and drives the first clamping member 110 to rotate relative to the second clamping member 120 through the driving member 221 to open and close.

[0046] In a specific implementation, the first clamping member 110 is disposed at one end of the rod body 210. The first clamping member 110 and the second clamping member 120 are disposed opposite each other and are hingedly connected to each other. For example, the first clamping member 110 is positioned close to the second clamping member 120 to clamp the foreign object. The first clamping member 110 is positioned away from the second clamping member 120 to release the foreign object.

[0047] Furthermore, the first clamping member 110 can be a mechanical clamp, and the second clamping member 120 can have a similar structure to the first clamping member 110, such as the second clamping member 120 also being a mechanical clamp. Alternatively, the second clamping member 120 can have a different structure from the first clamping member 110, such as the second clamping member 120 being a net bag with a fixed support force, which can also be provided with an extension portion. This application does not impose any restrictions on this. When the second clamping member 120 is also a clamp, a space for clamping foreign objects is formed between the two clamps.

[0048] It should be noted that in order to better clamp foreign objects, multiple forks or grids can be set on the mechanical gripper to ensure good wrapping of the outer peripheral side of the space for clamping foreign objects, thereby preventing foreign objects from falling between the two mechanical grippers.

[0049] In order to facilitate opening or closing the space for holding foreign objects formed by the first clamping member 110 and the second clamping member 120, the movable member 220 includes a movable rod 223 and a driving member 221 disposed on the movable rod 223, and the driving member 221 is slidably connected to the first clamping member 110. Exemplarily, when the movable rod 223 moves along the installation cavity 211 toward the first clamping member 110, since the movable rod 223 is connected to the driving member 221, the driving member 221 drives the first clamping member 110 to slide relative to the driving member 221, thereby causing the first clamping member 110 to rotate relative to the second clamping member 120 to close the space for holding foreign objects formed by the two. Since the foreign object is completely or partially located in the space, the foreign object is clamped, making it easier to clean the foreign object from the transformer heat sink.

[0050] The tool for cleaning foreign matter from a transformer heat sink in an embodiment of the present application is constructed by hingedly connecting a first clamping member 110 and a second clamping member 120 to open and close a space for clamping foreign matter, thereby clamping foreign matter and cleaning foreign matter from the transformer heat sink. A movable member 220 includes a movable rod 223 and a driving member 221 disposed on the movable rod 223. The driving member 221 is slidably connected to the first clamping member 110. The movable member 220 drives the first clamping member 110 to rotate relative to the second clamping member 120, thereby opening or closing the space formed by the first clamping member 110 and the second clamping member 120 to clamp foreign matter.

[0051] By pushing the movable rod 223 to move along the extension direction of the installation cavity 211, the driving member 221 drives the first clamping member 110 to approach the second clamping member 120, thereby clamping the foreign object. After the foreign object is clamped, the rod body 210 is moved to clamp the foreign object from the transformer heat sink. After the foreign object is clamped, the rod body 210 is moved again, so that the foreign object can be separated from the transformer heat sink in different directions, thereby facilitating the cleaning of foreign objects on the transformer heat sink. The tool for cleaning foreign objects in the transformer heat sink of the embodiment of the present application facilitates the cleaning of foreign objects on the transformer heat sink.

[0052] In some embodiments, the tool for cleaning foreign matter in a transformer heat sink provided in the present application has a sliding groove 2211 provided on the driving member 221 , and the first clamping member 110 slides along the sliding groove 2211 toward one end of the driving member 221 .

[0053] When implementing it specifically, Figure 4As shown, the driving member 221 is provided with a sliding groove 2211. One end of the first clamping member 110 is slidably connected to the sliding groove 2211. For example, when the movable rod 223 moves along the mounting cavity 211 toward the first clamping member 110, the driving member 221 slides along the sliding groove 2211 to approach the second clamping member 120, thereby clamping the foreign object. When the movable rod 223 moves toward the side away from the first clamping member 110, the driving member 221 slides in the opposite direction along the sliding groove 2211 to move away from the second clamping member 120, thereby releasing the foreign object and causing it to disengage.

[0054] In some embodiments, a sliding block is provided at one end of the first clamping member 110 facing the driving member 221 , and the sliding block is slidably connected to the sliding groove 2211 .

[0055] In this embodiment, the tool for cleaning foreign matter in the transformer heat sink is slidably connected to the first clamping member 110 via the sliding groove 2211, thereby driving the first clamping member 110 to rotate relative to the second clamping member 120, thereby opening and closing the space formed by the two to clamp foreign matter.

[0056] In some other embodiments, the tool for cleaning foreign objects in the heat sink of a transformer provided by the present application, the movable part 220 also includes a connecting rod 222 and an elastic part 224, the elastic part 224 is sleeved on the connecting rod 222, the elastic part 224 is located in the mounting cavity 211, one end of the elastic part 224 is connected to the movable rod 223, and the other end is connected to the inner wall of the mounting cavity 211, when the driving part 221 drives the first clamping part 110 to rotate relative to the second clamping part 120, the spring is compressed; the elastic part 224 is extended to reset the movable rod 223.

[0057] In a specific implementation, the elastic member 224 is sleeved on the connecting rod 222 , one end of the elastic member 224 is connected to the movable rod 223 , and the other end is connected to the inner wall of the installation cavity 211 .

[0058] When the movable rod 223 moves toward the first clamping member 110, the elastic member 224 is compressed. When the foreign object is separated from the clamping space formed by the first clamping member 110 and the second clamping member 120, the elastic member 224 stretches, driving the movable rod 223 to move away from the first clamping member 110, so that the movable rod 223 is reset, facilitating the next clamping action and reducing the steps of extracting the movable rod (223).

[0059] In some embodiments, the elastic member 224 may be a spring, which is not limited in the present application.

[0060] Among them, the tool for cleaning foreign objects in the heat sink of the transformer provided in this application, the first clamping member 110 includes a rotating rod 111, a hinge shaft 112 and a clamping member 113, one end of the rotating rod 111 is slidingly connected to the driving member 221, and the other end is connected to the clamping member 113, and the clamping member 113 is hinged to the second clamping member 120 through the hinge shaft 112.

[0061] In a specific implementation, one end of the rotating rod 111 is slidingly connected to the driving member 221 , and the other end is connected to the clamping member 113 . The clamping member 113 is sleeved on the hinge shaft 112 , and the clamping member 113 is hinged to the second clamping member 120 through the hinge shaft 112 .

[0062] For example, Figure 1 As shown, the connection between the rotating rod 111 and the clamping member 113 is annular and is mounted on the hinge shaft 112. There is a certain angle between the rotating rod 111 and the clamping member 113. The angle can be designed according to actual conditions and is not limited by this application. When one end of the clamping member 113 slides relative to the driving member 221, the other end of the clamping member 113 rotates around the hinge shaft 112. Because the rotating rod 111 is connected to the clamping member 113, it drives the clamping member 113 to rotate around the hinge shaft 112 to move closer to or away from the second clamping member 120, thereby closing or opening the space formed by the clamping member 113 and the second clamping member 120 to clamp foreign objects.

[0063] In some possible implementations, the tool for cleaning foreign matter in a transformer heat sink provided in the present application has a clamping portion 130 provided on both the first clamping member 110 and the second clamping member 120 , and the clamping portions 130 on the first clamping member 110 and the second clamping member 120 are opposite to each other.

[0064] In a specific implementation, the first clamping member 110 and the second clamping member 120 are both provided with a clamping portion 130 , which is used to abut against the clamped object to clamp the clamped object firmly and prevent the clamped object from slipping when the clamped object is moved.

[0065] In the tool for cleaning foreign matter in a transformer heat sink provided in the present application, the clamping portion 130 is serrated.

[0066] In a specific implementation, the clamping portion 130 is serrated, and the distribution number and inclination angle of the serrations on the clamping portion 130 can be adjusted and designed according to actual conditions, and this application does not impose any restrictions on this.

[0067] The serrated structure of the clamping portion 130 on the first clamping member 110 meshes with the serrated structure of the clamping portion 130 on the second clamping member 120. The tool of this application, through the serrated clamping portion 130, increases the frictional force of clamping foreign objects, providing a more secure grip between the first clamping member 110 and the second clamping member 120. Furthermore, different serrated structures can provide a tighter fit for foreign objects of varying sizes and shapes.

[0068] In addition, the tool for cleaning foreign matter in the transformer heat sink provided in the present application also includes a handle assembly 300, which includes a handle 310 and a hand rod 320. The handle 310 is connected to the hand rod 320, and the hand rod 320 is connected to the end of the movable rod 223 away from the driving member 221.

[0069] In a specific implementation, one end of the hand bar 320 is connected to the handle 310, and the other end is used to connect to the end of the movable rod 223 away from the driving member 221. Exemplarily, the extension direction of the handle 310 is perpendicular to the extension direction of the hand bar 320.

[0070] In some embodiments, the handle 310 may be provided with an anti-slip texture to facilitate the operator to apply force by holding the handle 310 .

[0071] It should be noted that, in the tool for cleaning foreign matter in the heat sink of a transformer provided in the present application, a force-applying portion 212 is provided on the rod body 210 . There are multiple force-applying portions 212 , which are arranged at intervals on the outer periphery of the rod body 210 .

[0072] In practice, since it is difficult to apply force to the handle assembly 300 when used vertically, it is difficult to pull the movable rod 223. Therefore, a force-applying portion 213 can be provided on the rod body 210 to provide a point of force for the handle assembly 300. The force-applying portion 212 is provided on the rod body 210 and cooperates with the handle assembly 300 to move the movable rod 223 along the extension direction of the mounting cavity 211.

[0073] In some embodiments, the operator can hold the force applying portion 212 with one hand to keep the rod body 210 stationary, and pull the handle assembly 300 with the other hand.

[0074] The tool for cleaning foreign matter in the heat sink of the transformer in the present application facilitates the operator to apply force through the force-applying portion 212 , thereby providing the operator with better grip support.

[0075] In some embodiments, the tool for cleaning foreign matter in the heat sink of a transformer provided in the present application has a first connection portion 321 provided on the hand lever 320 and a second connection portion 322 provided on the movable rod 223 , and the first connection portion 321 and the second connection portion 322 are threadedly connected.

[0076] In a specific implementation, the handle 320 is provided with a first connecting portion 321. The first connecting portion 321 can be convex and have an external thread on its surface. Correspondingly, the second connecting portion 322 can be a threaded hole that matches the first connecting portion 321. An operator rotates the handle 320 to screw the first connecting portion 321 and the second connecting portion 322 together. The tool for removing foreign matter from the transformer heat sink in this application facilitates assembly and disassembly of the movable rod 223 and the handle assembly through the first connecting portion 321 and the second connecting portion 322.

[0077] In some embodiments, the tool for cleaning foreign matter in a transformer heat sink provided by the present application has the handle 320 as a telescopic rod.

[0078] In a specific implementation, the handle 320 includes multiple telescopic rods, which are coaxially connected in sequence. The first end of the telescopic rod facing the movable rod 223 is provided with a first connecting portion 321, and the handle 320 is connected to the movable rod 223 via the first connecting portion 321. The tool of the present application is conveniently extended in length by the telescopic rod, and is suitable for grasping foreign objects at higher positions.
