Description

Technical Field

[0001] This utility model relates to the field of oil-immersed transformer welding technology, specifically to a welding clamping table for oil tanks of oil-immersed transformers. Background Technology

[0002] Oil-immersed transformers are a common type of power equipment, generally used to transmit high voltage over long distances to reduce line losses. They mainly consist of a core, windings, an oil tank, and a cooler. The core is the transformer's central component, composed of multiple silicon steel sheets, which effectively reduce iron losses and eddy current losses. The windings are conductor coils located on the core, converting electrical energy through magnetic field induction. The oil tank stores the transformer's insulating oil, which isolates and cools the windings. The cooler is a device that helps dissipate heat, typically using fans or water cooling.

[0003] The oil tank of an oil-fired transformer is an important component of the transformer. It is a pressure vessel formed by welding steel plates to hold insulating oil and protect the internal iron core and windings. However, the welding clamping platform of the oil tank of the existing oil-fired transformer is prone to releasing a large amount of harmful gases during the welding process. The harmful substances in the gases can easily cause harm to the health of the personnel around the equipment, which is detrimental to the welding work of the oil-fired transformer. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding clamping table for oil-fired transformer tanks, which solves the problem that existing welding clamping tables for oil-fired transformer tanks easily release large amounts of harmful gases during welding.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an oil-type transformer tank welding clamping table, including a worktable, with fixed columns fixedly connected to both ends of the top of the worktable, and a clamping mechanism provided between the two fixed columns;

[0006] The top of the workbench is equipped with a grid, the bottom of the workbench is connected to a conical hopper, the side wall of the conical hopper is connected to an air inlet pipe, the front side of the air inlet pipe is connected to a receiving box, the inner cavity of the receiving box is equipped with a negative pressure mechanism to extract the airflow inside the air inlet pipe, the bottom of the front side of the receiving box is connected to an exhaust pipe, the inside of the exhaust pipe is equipped with a filter structure, and the front side of the exhaust pipe is equipped with an exhaust window.

[0007] Furthermore, the clamping mechanism includes a support plate, a plurality of electric telescopic rods and a clamping plate. The support plate is fixedly connected between two fixed columns at the same end. The plurality of electric telescopic rods are all disposed on the support plate. The inner ends of the electric telescopic rods extend movably to the top of the workbench and are fixedly connected to the clamping plate.

[0008] Furthermore, a collection box is connected to the bottom of the conical hopper, and a drawer is provided on the collection box.

[0009] Furthermore, the negative pressure mechanism includes a support frame and several fans. The support frame is fixedly connected to the inner cavity of the receiving box, and the multiple fans are all fixedly connected to the surface of the support frame.

[0010] Furthermore, a number of reinforcing ribs are fixedly connected between the side wall of the bracket and the inner wall of the receiving box.

[0011] Furthermore, the filter structure includes an activated carbon plate and a polyester fiber membrane plate, with the activated carbon plate disposed on the front side of the exhaust pipe cavity and the polyester fiber membrane plate disposed on the rear side of the exhaust pipe cavity.

[0012] Furthermore, an inspection cover is installed on the front side of the container by means of several screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the oil tank of the oil-fired transformer on the upper surface of the grid, the oil tank can be fixed after the clamping mechanism works. During the welding process, the negative pressure mechanism works, and the airflow in the inner cavity of the conical bucket is drawn in through the air inlet pipe. The openings on the grid can be used to absorb and remove the fumes generated during welding, preventing the large-scale dispersion of fumes and avoiding health hazards to workers in the surrounding environment. This makes the device more environmentally friendly during use. Furthermore, the filtration structure can filter harmful substances in the fumes before emission, improving the health protection of workers and making the device safer during use.

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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a welding clamping table for an oil-type transformer tank, including a workbench 1, with fixed columns 17 fixedly connected to both ends of the top of the workbench 1, and a clamping mechanism provided between the two fixed columns 17.

[0022] The top of the workbench 1 is provided with a grid 16, the bottom of the workbench 1 is connected to a conical bucket 2, the side wall of the conical bucket 2 is connected to an air inlet pipe 6, the front side of the air inlet pipe 6 is connected to a receiving box 5, and the inner cavity of the receiving box 5 is provided with a negative pressure mechanism for extracting the airflow inside the air inlet pipe 6.

[0023] The bottom of the front side of the container 5 is connected to an exhaust pipe 10, the exhaust pipe 10 has a filter structure inside, and the front side of the exhaust pipe 10 has an exhaust window 15.

[0024] The oil tank of the oil-type transformer is placed on the upper surface of the grid 16, and the oil tank can be fixed by the clamping mechanism.

[0025] During the welding process, the negative pressure mechanism works, drawing airflow from the inner cavity of the conical bucket 2 through the air inlet pipe 6. By utilizing the openings on the grid 16, the welding fumes can be drawn in and removed, preventing large-scale dispersion of fumes and avoiding health hazards to workers in the surrounding environment. This makes the equipment more environmentally friendly during use.

[0026] The filtration structure can filter out harmful substances in flue gas before re-emission, improving the health protection of workers and making the equipment safer to use.

[0027] The clamping mechanism includes a support plate 18, several electric telescopic rods 19 and a clamping plate 20. The support plate 18 is fixedly connected between two fixed columns 17 at the same end. The multiple electric telescopic rods 19 are all set on the support plate 18. The inner end of the electric telescopic rod 19 extends movably to the top of the workbench 1 and is fixedly connected to the clamping plate 20.

[0028] When the electric telescopic rod 19 extends and moves, it causes the clamping plate 20 to come into contact with the side wall of the oil tank of the oil-type transformer, thereby fixing the oil tank of the oil-type transformer and improving the stability of the oil tank of the oil-type transformer during the welding process.

[0029] The bottom of the conical hopper 2 is connected to a collection box 3, and a drawer 4 is provided on the collection box 3. Solid particulate impurities generated during the welding process can fall into the drawer 4 through the inside of the conical hopper 2 and be collected in a concentrated manner, which is convenient for later recycling.

[0030] The negative pressure mechanism includes a support 7 and several fans 8. The support 7 is fixedly connected to the inner cavity of the housing 5, and the multiple fans 8 are fixedly connected to the surface of the support 7. After the fans 8 are working, they can draw the airflow inside the intake pipe 6 and inject it into the inner cavity of the exhaust pipe 10.

[0031] Several reinforcing ribs 9 are fixedly connected between the side wall of the bracket 7 and the inner wall of the container 5. The front side of the container 5 is disassembled and fitted with an inspection cover 14 by several screws 13.

[0032] The filter structure includes an activated carbon plate 11 and a polyester fiber membrane plate 12. The activated carbon plate 11 is disposed on the front side of the inner cavity of the exhaust pipe 10, and the polyester fiber membrane plate 12 is disposed on the rear side of the inner cavity of the exhaust pipe 10.

[0033] During operation, the oil tank of the oil-fired transformer is placed on the upper surface of the grid 16. When the electric telescopic rod 19 extends and moves, it causes the clamping plate 20 to come into contact with the side wall of the oil tank, thus fixing the oil tank. During the welding process, the negative pressure mechanism works, drawing airflow from the inner cavity of the conical bucket 2 through the air inlet pipe 6. The openings on the grid 16 are used to absorb and remove the fumes generated during welding, preventing the large-scale dispersion of fumes and avoiding health hazards to workers in the surrounding environment. The filtration structure can filter harmful substances in the fumes before releasing them, improving the health protection of workers.
