Description

Technical Field

[0001] The utility model relates to the field of refueling auxiliary tools, in particular to a refueling device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. During long-term use, the transformer will leak oil due to long-term use, so it needs to be refueled from time to time.

[0003] However, when refueling the transformer, a funnel is usually used for drainage and then refueling. During the use of the funnel, another operator is required to hold the funnel to maintain the stability of the funnel, which is not only very troublesome, but also very congested when two people operate at the same time, especially when the transformer is installed at a high position. The risk of accidents is increased. Therefore, the utility model provides a refueling device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a refueling device to solve the problem that during the use of the funnel, another operator is required to hold the funnel to maintain its stability, which is very troublesome. Two people operating at the same time not only limit the space and make the operation crowded, but also increase the risk of accidents.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A refueling device comprises a funnel chamber, the bottom end of which is fixedly connected with a funnel neck; a fixing assembly, which is used to improve the stability of the refueling device after being placed, and the fixing assembly is connected to the funnel neck.

[0007] Optionally, the fixing component includes a placement end and a fixing end clamped on the outside of the funnel neck, the placement end and the fixing end are integrally formed, and the thickness of the fixing end is smaller than the thickness of the placement end.

[0008] Optionally, the cross-section of the placement end is square, and a second air-permeable cavity is opened inside the placement end.

[0009] Optionally, the cross section of the fixed end is arc-shaped, a first air-permeable cavity is provided inside the fixed end, and the fixed end is divided into two by the first air-permeable cavity.

[0010] Optionally, the contact surfaces between the placement end and the fixing end and the funnel neck are each provided with two symmetrical connecting pieces, and the contact surfaces between the funnel neck and the connecting pieces are provided with slots matched with the connecting pieces.

[0011] Optionally, weakened grooves are provided at the grooves on the opposite surfaces of the two connecting pieces.

[0012] Optionally, a ventilation groove is provided on the outer wall of the funnel neck, and the ventilation groove corresponds to the fixing component.

[0013] Optionally, a drainage protrusion integrally formed with the air permeable groove is provided on the inner wall of the funnel neck.

[0014] Optionally, an arc-shaped guide groove is arranged outside the bottom end of the funnel neck.

[0015] Optionally, the fixing component is made of elastic material.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up a fixing component, during actual use, the funnel can be firmly fixed on the inner wall of the transformer refueling pipe through the extrusion force generated by the pressure deformation of the fixing component, so that a tight fit is formed between the funnel and the inner wall of the refueling pipe, thereby ensuring the stability of the funnel and avoiding oil leakage or inaccurate refueling caused by shaking or tilting during refueling. At the same time, it also reduces the need for operators to additionally support the funnel, thereby reducing the complexity of operation. Especially when the transformer is installed at a high position, this design can greatly reduce the burden on operators and improve the safety and efficiency of operations.

[0018] By providing the No. 1 breathable cavity and the No. 2 breathable cavity and the breathable groove, the air in the fuel tank will be gradually compressed during the refueling process, and flow out smoothly along the channel formed by the cavity and the channel formed between the fixed component and the funnel neck, which not only ensures the smoothness of refueling, but also effectively prevents problems such as oil overflow or slow refueling speed caused by air blockage, thereby improving the refueling rate. At the same time, by setting the placement end, it can be prevented that the funnel neck is directly embedded in the refueling pipe when fixed, which makes the internal gas unable to leak out, thereby ensuring the smoothness of refueling.

[0019] By providing a connecting piece, when the funnel needs to be cleaned, the operator only needs to pull out the connecting piece to remove the fixing component from the funnel, without using complicated tools or performing tedious disassembly steps, making the cleaning of the funnel more convenient and efficient. During cleaning, the operator can focus on cleaning the funnel body without worrying about the fixing component interfering with the cleaning process. At the same time, quick disassembly also reduces operation time and improves work efficiency. Moreover, when the fixing component is damaged, it can be quickly replaced, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is a detailed description of a refueling device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0030] It should be noted that the references to "one embodiment", "embodiment", "exemplary embodiments", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0031] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0032] It is to be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers.

[0033] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings.

The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0034] like Figure 1 to Figure 2As shown, an embodiment of the utility model provides a refueling device, including a funnel chamber 1, a funnel neck 2 is fixedly connected to the bottom end of the funnel chamber 1, a drainage protrusion 5 integrally formed with the air permeable groove 3 is arranged on the inner wall of the funnel neck 2, and an arc-shaped guide groove is opened at the bottom end of the funnel neck 2. When in use, the arc-shaped guide groove of the funnel neck 2 is aligned with the refueling pipe of the transformer. When the arc-shaped guide groove contacts the top of the refueling pipe, a natural guiding force is generated due to the arc-shaped surface, so that the funnel neck 2 can quickly slide into the interior of the refueling pipe for refueling. At the same time, after refueling, due to the existence of the internal drainage protrusion 5, the oil remaining on the inner wall of the funnel neck 2 can flow down faster along the angle between the two ends of the drainage protrusion 5, thereby effectively reducing the possibility of oil remaining on the inner wall of the funnel neck 2, avoiding oil waste and potential pollution problems.

[0035] In this embodiment, if Figures 1 to 5 As shown, the fixing component 4 is used to improve the stability of the refueling device after placement. The fixing component 4 is connected to the funnel neck 2. The fixing component 4 includes a placement end 401 and a fixed end 402 that are clamped on the outside of the funnel neck 2. The placement end 401 and the fixed end 402 are integrally formed. The cross section of the placement end 401 is square, and a second air permeable cavity 404 is provided inside the placement end 401. The cross section of the fixed end 402 is arc-shaped, and a first air permeable cavity 403 is provided inside the fixed end 402. The fixed end 402 is divided into two by the first air permeable cavity 403. A ventilation groove 3 is provided on the outer wall of the funnel neck 2, and the ventilation groove 3 corresponds to the fixing component 4. The thickness of the fixed end 402 is less than the thickness of the placement end 401. The fixing component 4 is made of elastic material. During use, the arc surface of the fixing end 402 first enters the refueling channel. As the fixing end 402 continues to enter, the convex surface of the fixing end 402 begins to deform and generates a force to squeeze the inner wall of the refueling channel. When the generated squeezing force is greater than the gravity of the funnel itself, the funnel neck 2 can be firmly fixed inside the refueling channel. It is fixed by physical squeezing, which is more stable and reliable than other fixing methods, and is simple to operate without complicated operations or additional tools. It only needs to put the funnel neck 2 into the refueling channel. Since the fixing end 402 can be deformed according to the shape of the refueling channel, this positioning mechanism can adapt to refueling channels of different shapes and sizes.

[0036] At the same time, after the fixed end 402 is fixed, a cavity is formed between the fixed end 402 and the funnel neck 2, and the cavity cooperates with the No. 1 breathable cavity 403, the No. 2 breathable cavity 404 and the breathable groove 3 to form an air permeable channel. When the oil enters the fuel tank, the air inside the fuel tank will be discharged through the formed channel, and the air inside the fuel tank can be continuously discharged, ensuring a smooth refueling process and avoiding slow refueling speed or refueling interruption caused by air blockage. The placement end 401 will move downward with the fixed end 402, and the bottom end of the placement end 401 will contact the transformer refueling port, thereby preventing the fixing component 4 from being completely inserted into the transformer refueling pipe due to excessive force, which will make it difficult to discharge the air and cause the problem of slow refueling.

[0037] The contact surfaces of the placement end 401 and the fixed end 402 with the funnel neck 2 are both provided with two symmetrical connecting pieces 405. The contact surfaces of the funnel neck 2 and the connecting piece 405 are provided with card slots adapted to the connecting piece 405. The grooves on the opposite surfaces of the two connecting pieces 405 are both provided with weakening grooves. After being used for a period of time, when removing, only the placement end 401 and the fixed end 402 need to be pulled. When the pulling force causes the connecting piece 405 to deform, the connecting piece 405 can be pulled out from the inside of the card slot. Similarly, the connecting piece 405 at the other end is pulled out synchronously. , and the fixing component 4 can be quickly removed. During cleaning, the operator can focus on cleaning the funnel body without worrying about the fixing component 4 interfering with the cleaning process. At the same time, quick disassembly also reduces the operation time and improves work efficiency. Moreover, when the fixing component 4 is worn, it can be quickly replaced, which improves practicality. During installation, it is only necessary to align the connecting piece 405 with the card slot, and use force to deform the connecting piece 405 at the weakened groove, so that the connecting piece 405 can be inserted into the inside of the card slot, thereby achieving quick installation.

[0038] The work flow provided by the utility model ensures that the funnel neck 2 and the fixing component 4 are intact, cleans the funnel device to ensure that there are no impurities or residues, aligns the connecting piece 405 of the fixing component 4 with the card slot on the funnel neck 2, and presses the connecting piece 405 into the card slot with force, and realizes rapid installation by weakening the deformation of the slot, ensuring that the fixing component 4 is firmly connected to the funnel neck 2, aligns the arc-shaped guide groove of the funnel neck 2 with the refueling pipe of the transformer, and gently slides the funnel neck 2 into the interior of the refueling pipe. The arc-shaped surface of the fixing end 402 will first contact the inner wall of the pipe, and as the funnel neck 2 goes deeper, the fixing The fixed end 402 is deformed and generates an extrusion force, fixing the funnel neck 2 in the refueling channel, and refueling begins. The oil flows into the refueling pipe through the funnel neck 2, and the air in the oil tank is discharged through the ventilation channel to ensure smooth refueling. The placement end 401 contacts the transformer refueling port to prevent the fixing component 4 from being fully inserted. After refueling is completed, gently pull the funnel neck 2 out of the refueling pipe. If the fixing component 4 needs to be cleaned or replaced, pull the placement end 401 and the fixed end 402 to pull the connecting piece 405 out of the slot. After cleaning or replacement, reinstall the fixing component 4 according to the installation steps.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiment of the present invention, and the present invention can be fully understood by those skilled in the art without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention.
