Description

Technical Field

[0001] The utility model relates to the technical field of transformer radiator mounting brackets, in particular to an external transformer radiator mounting bracket. Background Art

[0002] During the operation of the transformer, the loss in the windings and the core will generate a large amount of heat, which will cause the overall temperature of the transformer to rise. This heat needs to be dissipated in time. At this time, it is necessary to install a radiator on the transformer to conduct the heat inside the transformer to the heat sink through the heat conduction plate for heat dissipation. Otherwise, it will cause damage to the internal devices of the transformer. Most of the existing transformer radiators are installed on the outside of the transformer by means of an external mounting bracket.

[0003] Most of the existing transformer radiators and mounting brackets are fixedly connected to the transformer through a fixed structure. When the radiator needs to be replaced, it takes a lot of time to disassemble, and the disassembly is cumbersome, which reduces the replacement efficiency. At the same time, most of the existing mounting brackets are fixed structures, and each fixed bracket can only be used on the corresponding radiator, and the versatility is poor. Therefore, we propose an external transformer radiator mounting bracket to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6The utility model provides a technical solution: an external transformer radiator mounting bracket, comprising a transformer box 1, a radiator plate 2, a fixing plate 3, a first gear 4, a control rod 5, an upper rack 6, a lower rack 7, a first connecting rod 8, a first slide 9, a reinforcement rod 10, a second slide 11, a telescopic plate 12, a third slide 13, a nut 14, a bolt 15, a threaded rod 16, an extrusion plate 17, a clamping rod 18 and a damping rotation shaft 19, the transformer box 1 is connected to the outside of the radiator plate 2, and the radiator plate 2 is provided with a fixing plate 3, and the fixing plate 3 is provided with a first gear 4 in the center, the fixing plate 3 is connected to the damping rotation shaft 19 at the rear side, and the first gear 4 is connected to the control rod 19 at the inside. A control rod 5 is provided, and an upper rack 6 is connected to the upper side of the first gear 4, and a lower rack 7 is connected to the lower side of the first gear 4, a first connecting rod 8 is connected to the rear sides of the upper rack 6 and the lower rack 7, and a first sliding groove 9 is arranged in the first connecting rod 8, and a reinforcement rod 10 is arranged on the outer side of the first sliding groove 9, a second sliding groove 11 is arranged in the reinforcement rod 10, and a telescopic plate 12 is arranged in the second sliding groove 11, and a third sliding groove 13 is arranged at the center of the telescopic plate 12, a nut 14 is arranged on the third sliding groove 13, and a bolt 15 is connected to the nut 14, and a threaded rod 16 is connected inside the bolt 15, an extrusion plate 17 is arranged at the end of the threaded rod 16, and a clamping rod 18 is connected to the outer side of the telescopic plate 12.

[0023] The upper rack 6 and the lower rack 7 form a sliding groove movable structure with the first connecting rods 8 on both sides through the first sliding groove 9, so that the upper rack 6 and the lower rack 7 will not be stuck by the first connecting rod 8 when they follow the rotation and contraction of the first gear 4. At the same time, the force brought by the outside acts on the sliding structure composed of the first connecting rod 8 and the upper rack 6 and the lower rack 7, and the upper rack 6, the lower rack 7 and the first gear 4 form a gear transmission structure in the fixed plate 3, so that the upper rack 6 and the lower rack 7 can move by rotating the first gear 4.

[0024] The telescopic plate 12 forms a movable slide structure with the reinforcement rod 10 through the second slide groove 11, so that the telescopic plate 12 can move through the slide groove on the reinforcement rod 10. The reinforcement rod 10 reinforces the supporting structure, and the telescopic plate 12 forms a telescopic structure with the first gear 4 through their respective upper racks 6, lower racks 7 and first connecting rods 8, so that the telescopic plate 12 can be extended and retracted by rotating the first gear 4.

[0025] The threaded rod 16 is threadedly connected to the bolt 15 through the internal threaded through hole of the bolt 15, so that the threaded rod 16 can subsequently extrude the extrusion plate 17 by rotation, thereby extruding the radiator, and the threaded rod 16 is fixedly connected to the third slide groove 13 through the nut 14 and the bolt 15, and the position is fixed in the third slide groove 13 by the combination of the nut 14 and the bolt 15.

[0026] The fixed plates 3 are connected by a movable rod through a damping rotating shaft 19, and the mounting bracket is rotated to adapt to transformers of different heights. The control rod 5 passes through the two groups of fixed plates 3 and is connected to the first gear 4 inside the fixed plates 3, so that the first gears 4 in the two groups of fixed plates 3 can be uniformly controlled by the control rod 5, which is convenient for operation.

[0027] The clamping rod 18 is a polygonal structure, which is convenient for always having one side in contact with the transformer after the telescopic plate 12 moves, and the surface is covered with a strong magnet to improve the connection between the clamping rod 18 and the transformer.

[0028] Working principle: When using the external transformer radiator mounting bracket, first, when the radiator needs to be installed, first move the radiator plate 2 to the surface position of the transformer box 1 to be installed through the lifting device, and then rotate the fixing plate 3 so that the mounting bracket is separated by the damping rotating shaft 19 to form a staggered structure to wrap the transformer on the rear side of the radiator, and then rotate the control rod 5 in the center of the fixing plate 3 on the mounting bracket so that the first gear 4 inside the fixing plate 3 follows the rotation, so that the first gear 4 drives the upper rack 6 and the lower rack 7 on the upper and lower sides to move, and are respectively pulled out of the first sliding groove 9 in their respective first connecting rods 8, thereby driving the telescopic plate 12 connected to the upper rack 6, the lower rack 7, and the first connecting rod 8 to extend outward in the second sliding groove 11 in the reinforcement rod 10 until it extends to the required distance, and then stop rotating the control rod 5;

[0029] Then, the mounting bracket is pushed to make the radiator plate 2 close to the transformer box 1, and the control rod 5 is rotated in the opposite direction, so that the first gear 4 drives the upper rack 6, the lower rack 7, and the first connecting rod 8 to move inward, thereby contracting the telescopic plate 12 connected thereto inward, so that the telescopic plate 12 drives the outer clamping rod 18 to move inward, thereby clamping the transformer through the clamping rod 18, and when squeezed tightly, the bolt 15 is rotated to loosen the fixing structure composed of the bolt 15 and the nut 14 on the third slide groove 13 in the telescopic plate 12, and then the moving bolt 15 is made until the bolt 15 reaches the exposed heat conducting plate on the outer side of the radiator plate 2, and then the threaded rod 16 inside the bolt 15 is rotated to drive the extrusion plate 17 to move toward the exposed heat conducting plate on the outer side of the radiator plate 2, and finally the radiator plate 2 is squeezed and fixed by the extrusion plate 17, so that the radiator is fixed on the transformer box 1, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
