Description

Technical Field

[0001] This utility model belongs to the field of plate radiator installation technology, specifically relating to a support structure for plate radiators. Background Technology

[0002] Transformers are essential electrical equipment in the power industry. Plate-type radiators, as supporting components for transformers, are mainly used for circulating heat dissipation in oil-immersed transformers. They dissipate the heat generated inside the transformer to the surrounding air, ensuring the transformer's operating temperature remains within a safe range and guaranteeing safe operation. Plate-type radiators are generally installed on the transformer via flanges or directly welded to it. Their interior is directly connected to the transformer oil tank and filled with transformer oil. Therefore, the sealing performance requirements for both the plate-type radiator and its connection to the transformer oil tank are very high. Furthermore, the larger the transformer capacity, the more heat dissipation is required. The larger the heat dissipation area, the more fins the radiator needs to have, thus increasing its weight. Furthermore, radiators are typically installed in multiple units or welded to the transformer, placing significant tensile stress on the transformer tank walls and straining the tank's steel plates. Excessive weight can also lead to insufficient connection strength between the transformer tank and the radiator, causing weld cracking or loose bolts due to the weight of the radiator. This can result in oil leakage from the transformer tank, affecting the safe operation of the power system. Therefore, this paper proposes a support structure for radiators to address these issues. Utility Model Content

Detailed Implementation

[0017] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] See Figure 1 and Figure 2 This embodiment provides a support structure for a plate-type radiator, disposed between a transformer 5 and a plate-type radiator 6, including a mounting base plate 1, a first support seat, a support adjustment rod assembly, and a second support seat. In this embodiment, the mounting base plate 1 is fixedly installed on the surface of the transformer 5 or the transformer 5 tank, and symmetrical mounting sliding holes 11 are provided on both sides for mounting and fixing to the surface of the transformer 5 or the transformer 5 tank. Furthermore, a splicing notch 12 is provided on one outer edge of the mounting base plate 1, and a splicing protrusion 13 is provided on the other outer edge for splicing and matching with another mounting base plate 1. This allows multiple support structures to be combined and installed to cope with support work for heavy weights or other complex situations.

[0019] The first support base includes a first support plate 21 and two sets of symmetrically arranged support legs 22. The bottom ends of the support legs 22 are fixedly disposed on both sides of the mounting base plate 1, and the top ends of the support legs 22 are inclined inwards near the center. The support plate is connected to the top ends of the two sets of support legs 22. At this time, the connection angle between the support legs 22 and the first support plate 21 is maintained between 120° and 135°. The second support base includes a second support plate 31 and two sets of symmetrically arranged support arms 32. The bottom ends of the two sets of support arms 32 are inclined inwards near the center and are finally arranged opposite each other on both sides of the second support plate 31. At this time, the support arms 32 and the second support plate 31 are connected. The connection angle between the two sets of support arms 32 is maintained between 120° and 135°. A connecting crossbar 33 is provided at a position slightly above the two sets of support arms 32, and a support frame 34 is provided at the top of each support arm 32. The support frame 34 is used to stably place the connecting plate radiator 6. It specifically includes a placement plate 35 provided at the top of the support arm 32, a buffer pad layer 36 provided on the placement plate 35, and a protective plate 37 provided on the buffer pad layer 36. This allows it to stably contact the surface of the plate radiator 6, which undergoes slight sagging and elastic deformation due to the presence of variable pressure oil, after the plate radiator 6 is filled with oil. It also bears and counteracts the uneven pressure caused by the weight of the variable pressure oil during its flow, thus completely solving the problem of uneven force on the upper and lower parts of the plate radiator. Furthermore, both the first support plate 21 and the second support plate 31 are provided with adjustment holes (not shown in the figure) at their center positions. At the same time, both the first support plate 21 and the second support plate 31 are provided with a plurality of support grooves (not shown in the figure) arranged around the adjustment holes, and the positions of the support grooves on the first support plate 21 and the second support plate 31 are symmetrically corresponding. In addition, the connection between the support foot 22 and the mounting base plate 1, and the connection between the support arm 32 and the support frame 34 are provided with limit locks 23 to facilitate the disassembly and replacement of the side support plate 44 between the mounting base plate 1 and the support frame 34.

[0020] In this embodiment, the angle between the support foot 22 and the first support plate 21 and the angle between the support arm 32 and the second support plate 31 are both set to 120°. The outer surfaces of the first support plate 21 and the second support plate 31 are uniformly provided with anti-slip protrusions (not shown in the figure). The number of support grooves on the first support plate 21 and the second support plate 31 is set to 6.

[0021] The support adjustment rod assembly is used to connect the first support base and the second support base and adjust their relative position and spatial gap, so that the support structure can be better installed between the transformer 5 and the plate heat sink 6. It also bears and evenly distributes the pressure generated by the weight of the plate heat sink 6 between the first and second support bases. The assembly includes a main adjustment screw 41, a first support rod assembly, and a second support rod assembly. The bottom end of the main adjustment screw 41 is fixedly mounted on the mounting base plate 1, and its main body passes through the adjustment hole at the center of the first support plate 21 and the second support plate 31. This allows the second support base to be detachably and adjustably connected above the first support base. Two sets of locking nuts 42 are also provided on the main adjustment screw 41. The second support plate 31 on rod 41 has two sides for locking and fixing the second support seat; the first support rod group includes a number of short support rods 43, the number of which is less than or equal to the number of support slots on the first support plate 21, and in actual application, the short support rods 43 of appropriate length can be selected and replaced in the support slots according to the distance between the first support seat and the second support seat to enhance the support strength between the first support seat and the second support seat; the second support rod group includes two sets of side support plates 44, and the side support plates 44 can also be adjusted and replaced with side support plates 44 of appropriate height according to the distance between the first support seat and the second support seat in actual application to support the mounting base plate 1 and the support frame 34.

[0022] In this embodiment, the above is merely an example and is not intended to limit the scope of protection of this application.

[0023] This utility model provides a support structure for a plate-type radiator. By fixing a mounting base plate to a transformer, the radiator is supported from below by a first and second support base, providing a vertical upward support force. The support frame at the top of the second support base, consisting of a placement plate, a buffer pad, and a protective plate, can stably contact the surface of the plate-type radiator, which undergoes slight sagging and elastic deformation due to the presence of transformer oil after oil filling. It also absorbs and counteracts the uneven pressure caused by the weight of the flowing transformer oil, completely solving the problem of uneven stress distribution. This increases the connection strength between the plate-type radiator and the transformer or transformer tank, ensuring the safety of the transformer or transformer tank. The design prevents deformation and avoids damage to the connection welds or mounting flanges between the two supports, allowing for adaptive adjustments and reinforcement of the support position. Simultaneously, the main adjusting screw of the support adjustment rod assembly allows for flexible adjustment of the relative height distance between the first and second support seats, accommodating various specifications of radiator plates and transformers or transformer tanks.
