Description

Technical Field

[0001] The utility model relates to a heat dissipation device for a transformer, in particular to a reel-type radiator dustproof device which is mainly used for heat dissipation of a transformer with strong oil-air cooling. Background Art

[0002] The normal operation of the transformer of the power equipment will inevitably generate heat during energy conversion. The increase in the temperature of the transformer will increase the internal friction and affect the output efficiency. Excessive temperature will also cause the transformer to burn out. It is necessary to dissipate the heat through a heat dissipation device to prevent the transformer from overheating. Later, in order to improve the heat dissipation effect, a patent number of 201710486368.7 was disclosed in the prior art, and the name is a radiator dustproof net cover invention patent. The patent installs a pulley and a reversing wheel on a fixed plate, and drives the winch to retract and release the wire rope through a motor control box to control the dustproof net to move along the U-shaped guide groove. The dustproof net can be unfolded upward or folded downward for stacking. Dust, grass clippings, poplar fluff, insects and other debris can be blocked through the dustproof net, which reduces the adsorption and accumulation of debris on the radiator fins of the transformer, making the heat dissipation device network unobstructed and improving the heat dissipation effect of the radiator. However, since the dustproof net cover of the radiator is a folding structure, for the strong oil-air cooling radiator, due to the different manufacturers of the strong oil-air cooling radiator, the power of the main transformer used is different, and the installation method of the installation company is also different. Therefore, the structure of the strong oil-air cooling radiator is inconsistent, which brings great trouble to the unified design and installation. Therefore, there are mainly the following problems:

[0003] (1) The distance between the oil-cooled radiator and the frame structure is very close, and the folded mesh cannot be unfolded up and down;

[0004] (2) The folded mesh is mainly based on a frame structure, which will affect the ventilation volume of the oil-cooled radiator and reduce the heat dissipation performance of the oil-cooled radiator;

[0005] (3) The folding mesh is not very versatile, which brings great difficulties and troubles to design and installation;

[0006] (4) Since the dust screen needs to be manually powered off on site each time the folding mesh is operated, it is time-consuming and laborious. Summary of the invention

[0007] The technical problem to be solved by the utility model is to provide a roll-type radiator dustproof device which is convenient and quick to install, time-saving and labor-saving to operate and has strong versatility.

[0008] The utility model discloses a roll-up radiator dustproof device, comprising a dustproof net for preventing dust, a dustproof net reeling device for reeling up the dustproof net, and a pulling device for pulling the dustproof net. The pulling device is connected to the dustproof net and can pull the dustproof net out of the dustproof net reeling device under the pulling force provided by the pulling device to block the dustproof net at the front side of the air inlet of the radiator. The dustproof net is provided with a reinforcing structure for increasing the strength. The front side of the air inlet of the radiator (17) is provided with a plurality of vertical support rods. The reinforcing structure cooperates with the vertical support rods to prevent the dustproof net from being deformed.

[0009] The dust-proof net winding device includes a drum, a reel mounted on the drum, drum side plates mounted on the left and right ends of the drum and used to support the reel, a spiral spring for controlling the dust-proof net, and a spring fixing ring located on the outside of the drum side plate and used to place the spiral spring.

[0010] The pulling device comprises a lifting pulley, a reversing pulley, a power device installed beside the radiator, and a lifting wire rope connected to the dustproof net and connected to the power device after passing through the lifting pulley and the reversing pulley.

[0011] A lifting plate is arranged at the top of the dustproof net, and at least one stressed steel wire rope is arranged between the lifting plate and the dustproof net winding device.

[0012] The reinforcement structure is a plurality of transverse reinforcement ribs arranged transversely on the dustproof net.

[0013] The radiator has a supporting frame and a top beam fixedly installed on the top of the supporting frame, the lifting pulley is installed in the middle of the top beam, the reversing pulley is installed on the side of the top beam, the dust net winding device is arranged at the bottom of the supporting frame, the tension device is installed on the side of the supporting frame, and the lifting wire rope is successively passed around the lifting pulley and the reversing pulley and connected to the tension device.

[0014] The power device comprises a motor, a winch driven by the motor and an electric control box for controlling the motor, and the lifting wire rope is connected to the winch.

[0015] An upper limit travel switch connected to the electric control box is installed on the top of the support frame; a lower limit travel switch also connected to the electric control box is installed on the bottom of the support frame.

[0016] The dustproof net also includes a mounting frame and a screen is arranged in the mounting frame.

[0017] Z-shaped guide grooves are installed in front of both sides of the radiator, and both side edges of the dustproof net are clamped in the Z-shaped guide grooves and can move up and down along the Z-shaped guide grooves.

[0018] The advantages of the utility model are:

[0019] (1) By providing a dustproof net for dust prevention, a dustproof net rolling device for rolling up the dustproof net, and a pulling device for pulling the dustproof net, the dustproof net rolling device is cleverly utilized to roll up the dustproof net to form a small volume structure and block it in front of the air inlet of the radiator, thereby solving the problem of inconsistent structures of the forced oil-air-cooled radiators due to different manufacturers, different powers of the main transformers used, and different installation methods of the installation companies, which brings troubles to unified design and installation.

[0020] (2) The dustproof net mainly includes a mounting frame, a screen placed inside the mounting frame and necessary transverse reinforcing ribs as a reinforcing structure, thereby ensuring the ventilation volume of the oil-cooled radiator and solving the problem of small ventilation volume of the folded mesh.

[0021] (3) Its structural design is simple, installation is very convenient, and it has good versatility, making it easy to design and install and reliable and safe to use;

[0022] (4) The unwinding and rewinding are realized by directly cooperating with the pulling device and the dust-proof net rewinding device, which solves the problem that the original folding net adopts a point-to-point lifting method and the lifting and lowering of multiple sets of dust-proof nets takes too long.

[0032] The following is a further detailed description of the roll-type radiator dustproof device of the present invention in conjunction with the accompanying drawings and specific implementations.

[0033] As shown in the figure, the utility model of the reel-type radiator dustproof device includes a dustproof net 14 for dustproofing, a dustproof net winding device 16 for winding up the dustproof net, and a pulling device 8 for pulling the dustproof net, wherein the dustproof net 14 includes a mounting frame and a screen is arranged in the mounting frame, the pulling device 8 includes a lifting pulley 3, a reversing pulley 4, a power device installed on the side of the radiator, and a lifting wire rope 9 connected to the dustproof net 14 and connected to the power device after passing through the lifting pulley 3 and the reversing pulley 4, the power device includes a motor, a winch driven by the motor, and an electric control box for controlling the motor, the lifting wire rope 9 is connected to the winch, the lifting wire rope 9 of the pulling device 8 is connected to the dustproof net 14 and can pull the dustproof net 14 under the pulling force provided by the pulling device Pull out the dust net winding device 16 to block the front side of the air inlet of the radiator 17, and a reinforcing structure for increasing the strength is provided on the dust net 14. As can be seen from the figure, the reinforcing structure is a plurality of transverse reinforcing ribs 15 arranged transversely on the dust net. The function of the reinforcing structure is to increase the strength of the dust net 14, so that the dust net 14 will not be deformed by the strong suction force generated when the strong oil-air-cooled radiator is working when it is in use. In coordination with it, two to three lifting rails 13 are added vertically in front of the strong oil-air-cooled radiator on each group of strong oil-air-cooled radiators (that is, a plurality of vertical support rods 13 are provided on the front side of the air inlet of the radiator 17). The function of the lifting rails 13 is to prevent the dust net 14 from being deformed by strong wind when in use, and interact with the transverse reinforcing ribs 15 of the dust net. The deformation of the dust net 14 can be prevented by cooperating with the reinforcing structure and the vertical support rods.

[0034] Furthermore, the dust net winding device 16 includes a drum 24, a reel mounted with the drum, a drum side plate 20 mounted on the left and right ends of the drum and used to support the reel, a scroll spring 23 for controlling the dust net 14, and a spring fixing ring 22 located outside the drum side plate 20 and used to place the scroll spring 23. The drum 24 is installed through a drum mounting plate 21, and the scroll spring 23 is covered with a spring cover 24. The dust net drum 16 tightens the dust net 14 mainly under the control of the scroll spring 23. When the dust net 14 is unfolded, the scroll spring 23 is also unfolded. When the dust net 14 is retracted, the scroll spring 23 automatically The dust-proof net 14 is recovered and driven by the dust-proof net drum 16 to rewind the dust-proof net 14. It can be seen from the above structure that the lifting and unfolding of the dust-proof net 14 is mainly affected by the tension of the lifting wire rope 9. When the dust-proof net 14 is subjected to the tension, the dust-proof net rewinding device 16 is also affected by the tension, and the corresponding parts of the dust-proof net rewinding device also roll synchronously with the dust-proof net 14. At this time, the vortex spring 23 is affected by the force of the dust-proof net drum 16, and the vortex spring 23 also releases elastic energy. When the dust-proof net 14 recovers, the lifting wire rope 9 releases the tension. At this time, the vortex spring 23 is weakened by the force of the drum, and the vortex spring 23 also retracts the elastic energy, forcing the dust-proof net rewinding device 16 to recover the dust-proof net 14.

[0035] Furthermore, a lifting plate 11 is provided at the top of the dust-proof net 14, and the lifting wire rope 9 of the tension device 8 is connected to the middle position of the top of the lifting plate 11. At least one force-bearing wire rope 19 is provided between the lifting plate 11 and the dust-proof net winding device 16, that is to say, each dust-proof net 14 is passed through the dust-proof net 14 multiple times by one or more protective wire ropes 19, one end of the protective wire rope 19 is fastened to the net lifting plate 11, and the other end is fixed to the dust-proof net winding device 16. When the dust-proof net 14 is lifted and unfolded, it is not directly affected by the tension of the lifting wire rope 9, but is protected by the force-bearing protective wire rope 19, and the force on the protective wire rope 19 is greater than that on the dust-proof net 14.

[0036] Furthermore, the radiator 17 has a support frame and a top beam 2 fixedly mounted on the top of the support frame, a lifting pulley 3 is mounted in the middle of the top beam 2, a reversing pulley 4 is mounted on the side of the top beam 2, a dust screen winding device 16 is arranged at the bottom of the support frame, and a tension device 8 is mounted on the side of the support frame. The lifting wire rope 9 is sequentially passed around the lifting pulley 3 and the reversing pulley 4 and connected to the tension device. An upper limit travel switch 5 connected to the electric control box is installed on the top of the support frame; a lower limit switch 5 also connected to the electric control box is installed at the bottom of the support frame. Limit travel switch 6, when the winch drives the hook through the wire rope to drive the dustproof net 14 to move upward, the upper edge of the net lifting plate 11 contacts the upper limit travel switch 5, and the upper limit travel switch sends a command signal to control the winch to stop rotating. When the dustproof net drops to hit the lower limit travel switch, the motor stops rotating, the dustproof net no longer drops, and is recovered on the dustproof net winding device 16. In addition, Z-shaped guide grooves 18 are installed in front of the frames on both sides of the radiator and are fixed by C-shaped clamps 7. The two side edges of the dustproof net 14 are clamped in the Z-shaped guide grooves 18 and can move up and down along the Z-shaped guide grooves 18.

[0037] In addition, at least one hook 10 can be installed on the top of the dustproof net 14. A hook 10 can be set in the middle position of the top of the dustproof net 14, or two hooks 10 can be set at positions symmetrical to each other on both sides, or a middle hook 10 and two symmetrical hooks 10 can be set in combination. The present embodiment adopts the scheme of the middle hook; the hook 10 is connected to the lifting wire rope 9, that is: the hook 10 of the present embodiment is installed in the middle position of the upper side of the topmost net lifting plate 11, and the dustproof net 14 is moved upward along the Z-shaped guide groove 18 by the hook 10. A lifting slider 12 is provided on the lifting plate 11, and the subsequent dustproof net 14 is driven to move upward and unfold to cover the front of the radiator air inlet through the cooperation of the lifting slider 12 and the vertical support rod 13.

[0038] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
