Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer oil injection mechanism. Background Technology

[0002] Transformer oil is a mineral oil obtained from petroleum through distillation and refining. It is a fractionation product of petroleum and its main components are compounds such as alkanes, cycloalkanes, and aromatic unsaturated hydrocarbons. Commonly known as transformer oil, it is a light yellow transparent liquid. Transformer oil has good insulation, heat dissipation, and arc suppression properties. In transformers, it plays a role in insulation, heat dissipation, arc suppression, and protection of internal transformer components from oxidation, aging, and corrosion.

[0003] Currently, transformer oil is stored in the oil conservator. The main function of the transformer oil conservator is to act as an expansion chamber for the oil. When the transformer load increases or the oil temperature rises, causing the oil in the tank to expand, the excess oil will flow into the oil conservator. Conversely, when the temperature drops, the oil in the oil conservator will flow back into the tank, thus automatically adjusting the oil level and ensuring that the tank is always full of oil. When a transformer leaks, transformer oil needs to be added to the oil conservator.

[0004] In the existing technology, personnel directly lift and raise the container containing transformer oil to the high place where the transformer is installed, which increases the load on the personnel climbing up and thus increases labor. Therefore, a transformer oil injection mechanism is proposed, in which a pump draws out the transformer oil from the container and transports it to a high place for easy injection into the oil tank. A geared motor drives the bundle tube assembly to rotate, which can retract and extend the cable, making it convenient to put the top of the outlet tube into the oil tank. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides a transformer oil injection mechanism. The pump draws transformer oil from the container and transports it to a higher position for easy injection into the oil conservator. The geared motor drives the bundle tube assembly to rotate, which can retract and extend the cable, making it convenient to insert the top of the outlet tube into the oil conservator.

[0006] The technical solution adopted by this utility model to solve its technical problem is a transformer oil injection mechanism, including a winding disc, a protective tube and a through hole. A liquid pump is installed inside the winding disc by a mounting bracket. A drive assembly is provided on the top of the winding disc. The drive assembly includes a first protective box fixed to the top of the winding disc by bolts. An energy storage box is provided inside the first protective box. A second protective box is provided on the top of the first protective box. A geared motor is installed inside the second protective box by a mounting bracket.

[0007] The second protective box is provided with a tube assembly on the top. The tube assembly includes an L-shaped connecting rod that is fixed to the top output shaft of the geared motor by bolts. A limit frame is fixed to one side of the L-shaped connecting rod by bolts. A guide wheel is rotatably connected inside the limit frame by bearings. The tube is mounted on the top side of the L-shaped connecting rod by a mounting bracket.

[0008] By adopting the above technical solution, the geared motor drives the L-shaped connecting rod to rotate, which in turn moves the liquid outlet pipe through the bundle tube to reel in and unload the wire, and the liquid pump works to transfer the transformer oil in the container to the oil tank.

[0009] Specifically, a through hole is provided on one side of the winding disc, and a protective tube is provided at the bottom of the through hole.

[0010] Specifically, the inlet end of the pump is fixed with an inlet pipe by a clamp, the inlet pipe passes through the protective pipe, and the bottom end of the inlet pipe is connected to a filter screen via a pipe joint.

[0011] Specifically, the outlet end of the pump is fixed with an outlet pipe by a clamp. The outlet pipe passes through a through hole and is wrapped around the outside of the winding disc. The end of the outlet pipe away from the pump passes through the limiting frame and the bundle tube in sequence.

[0012] Specifically, the top of the liquid outlet pipe is connected to a structural cylinder via a pipe joint, a glass window is provided on one side of the structural cylinder, and a tapered tube is connected to the top of the structural cylinder via a threaded groove.

[0013] Specifically, the current output terminal of the battery storage box is electrically connected to the current input terminals of the geared motor and the liquid pump via a power supply line.

[0014] The beneficial effects of this utility model are:

[0015] The transformer oil filling mechanism described in this utility model uses a geared motor to drive an L-shaped connecting rod to rotate, which in turn drives the outlet pipe to rotate through a bundle tube. This loosens the outlet pipe that is wound around the outside of the winding disc, allowing personnel to pull the outlet pipe by holding the structural cylinder. The conical tube is then inserted into the oil filling port of the oil tank. The pump is turned on to draw transformer oil from the container through the inlet pipe and deliver it to the structural cylinder through the outlet pipe. Finally, the oil is added to the oil tank through the conical tube, eliminating the need to lift the container containing the transformer oil. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The pump draws transformer oil from the container and transports it to a higher position for easy injection into the oil conservator. A geared motor drives the bundled tube assembly to rotate, allowing for cable retraction and unwinding, facilitating the insertion of the outlet tube tip into the oil conservator. Figure 1-5 As shown, the transformer oil injection mechanism of this utility model includes a winding disc 1, a protective tube 101, and a through hole 102. A liquid pump 4 is installed inside the winding disc 1 through a mounting bracket. A drive assembly 2 is provided on the top of the winding disc 1. The drive assembly 2 includes a first protective box 201 fixed to the top of the winding disc 1 by bolts. An energy storage box 202 is provided inside the first protective box 201. A second protective box 203 is provided on the top of the first protective box 201. A reduction motor 204 is installed inside the second protective box 203 through a mounting bracket.

[0025] The second protective box 203 has a bundle tube assembly 3 on its top. The bundle tube assembly 3 includes an L-shaped connecting rod 301 that is fixed to the top output shaft of the geared motor 204 by bolts. A limit frame 302 is fixed to one side of the L-shaped connecting rod 301 by bolts. A guide wheel 303 is rotatably connected inside the limit frame 302 by bearings. A bundle tube 304 is mounted on the top side of the L-shaped connecting rod 301 by a mounting bracket.

[0026] During use, the geared motor 204 drives the L-shaped connecting rod 301 to rotate, which in turn drives the outlet pipe 402 to move through the bundle tube 304 to reel in and unload the wire. The pump 4 operates to transfer the transformer oil in the container to the oil tank.

[0027] For example, such as Figure 2 As shown, the present invention also includes a through hole 102 on one side of the winding disc 1, and a protective tube 101 at the bottom of the through hole 102.

[0028] In use, the opening of the through hole 102 facilitates the passage of the liquid outlet pipe 402, and the opening of the protective tube 101 facilitates the passage of the liquid inlet pipe 401.

[0029] For example, such as Figure 3 As shown, the present invention also includes an inlet pipe 401 fixed to the inlet end of the liquid pump 4 by a clamp, the inlet pipe 401 passing through the protective pipe 101, and a filter screen 5 connected to the bottom end of the inlet pipe 401 by a pipe joint.

[0030] When in use, the filter screen 5 can filter the transformer oil drawn into the liquid inlet pipe 401, and can filter out impurities, particulate matter, etc.

[0031] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a liquid outlet pipe 402 fixed to the liquid outlet end of the liquid pump 4 by a clamp. The liquid outlet pipe 402 passes through the through hole 102 and is wound around the outside of the winding disc 1. The end of the liquid outlet pipe 402 away from the liquid pump 4 passes through the limiting frame 302 and the bundle tube 304 in sequence.

[0032] When in use, the liquid outlet tube 402 is wrapped around the outside of the winding disc 1 for easy storage.

[0033] For example, such as Figure 3 As shown, the present invention also includes a structural cylinder 6 connected to the top of the liquid outlet pipe 402 via a pipe joint, a glass window 7 provided on one side of the structural cylinder 6, and a tapered pipe 8 connected to the top of the structural cylinder 6 via a threaded groove.

[0034] During use, the structural cylinder 6 and the glass window 7 facilitate personnel to observe the transformer oil being added, while the tapered tube 8 serves as a guide.

[0035] For example, such as Figure 4 As shown, the present invention also includes an electric connection between the current output terminal of the battery storage box 202 and the current input terminal of the geared motor 204 and the liquid pump 4 via a power supply line.

[0036] When in use, the storage box 202 supplies power to the geared motor 204 and the liquid pump 4, so that the device does not need to be connected to an external power source.

[0037] When using this utility model, the operator places the winding reel 1 on a container containing transformer oil, puts the filter screen 5 at the bottom of the liquid inlet pipe 401 into the container, and the storage box 202 supplies power to the geared motor 204 and the liquid pump 4.

[0038] Personnel turn on the geared motor 204 to drive the L-shaped connecting rod 301 to rotate. The rotation of the L-shaped connecting rod 301 drives the outlet pipe 402 to rotate through the bundle tube 304. The outlet pipe 402, which is wrapped around the outside of the winding disc 1, is loosened. Personnel can then pull the outlet pipe 402 by holding the structural cylinder 6. The cone pipe 8 is inserted into the oil filling port of the oil tank. The pump 4 is turned on to extract the transformer oil from the container through the inlet pipe 401 and deliver it to the structural cylinder 6 through the outlet pipe 402. The oil is then added to the oil tank through the cone pipe 8.

[0039] The condition of the transformer oil inside the structural cylinder 6 can be observed through the glass window 7. After the filling is completed, the geared motor 204 is turned on to drive the L-shaped connecting rod 301 to reverse. This allows the outlet pipe 402 to be rewound around the outer side of the inlet pipe 401. The setting of the bundle tube 304 and the guide wheel 303 can constrain the outlet pipe 402 without affecting its movement.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
