Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and specifically provides a top-protected Chinese-style box transformer. Background Art

[0002] With the promotion of new energy, Chinese-style box-type transformers are gradually used in wind power projects. During construction, Chinese-style box-type transformers are usually installed under the wind turbine.

[0003] However, the winter temperature in different regions is different. In areas with lower winter temperatures, ice will form on the fan and fan blades. Since the Huashi box-type transformer is located at the bottom of the fan, when the ice on the fan and fan blades falls frequently, it will directly hit the top of the Huashi box-type transformer, which is easy to cause damage to the Huashi box-type transformer. Therefore, the problem that the Huashi box-type transformer is easily damaged by falling ice cubes needs to be solved urgently. Utility Model Content

[0004] The utility model provides a top-protected Hua-style box transformer, which is used to solve the problem that the Hua-style box transformer is easily damaged by falling ice cubes.

[0005] The technical solution of the utility model is as follows:

[0006] A top-protected Chinese-style box-type transformer comprises a box body, a radiator and a ceiling. The radiator is arranged on one side of the box body, and the radiator and the top of the box body are respectively provided with a ceiling.

[0007] In this solution, a ceiling is set on the top of the radiator and the box, which can block the falling ice cubes, thereby preventing the ice cubes from falling directly on the radiator and the box, preventing the radiator and the box from being damaged by the ice cubes, and playing a role in protecting the radiator and the box.

[0008] Preferably, the ceiling includes a first shelf body and a second shelf body, the radiator includes a bracket for mounting a heat sink, the first shelf body is arranged on the top of the bracket for mounting the heat sink, and the second shelf body is arranged on the top of the box body.

[0009] In this solution, the radiator and the box have different heights, and the distance between the heat sink of the radiator and the box is large. Therefore, a first shed and a second shed can be respectively set on the top of the radiator and the box. The first shed and the second shed can be installed at different heights to facilitate the installation of the ceiling.

[0010] Preferably, a mounting ear plate is provided on the top of the radiator, and the first shelf is connected to the mounting ear plate.

[0011] In order to solve the problem of uneven force on each mounting ear plate, at least two mounting ear plates are arranged on the top of the radiator, the first shelf is indirectly connected to the mounting ear plate, a connecting piece is arranged between the first shelf and the mounting ear plate, and the connecting piece is respectively connected to each mounting ear plate.

[0012] In this solution, each mounting ear plate is connected to a connecting member, and the connecting member is connected to the first shelf body. When the first shelf body is subjected to force, the force is transmitted to each mounting ear plate through the connecting member, so that the force can be dispersed to each mounting ear plate, thereby preventing a single mounting ear plate from being damaged due to excessive force.

[0013] Preferably, the Chinese-style box-type transformer further includes at least two fixing members, and the fixing members are respectively connected to the connecting member and the first shed body.

[0014] In this solution, the provision of the fixing member can increase the height of the first shed body, thereby increasing the distance between the first shed body and the second shed body, increasing the operating space during installation, and facilitating installation.

[0015] The radiator of the Hua-style box transformer includes a heat sink and a cylindrical structure. The top of the heat sink bracket is relatively flat, which is convenient for installing the first shed, while the top of the cylindrical structure is uneven, making it difficult to install the first shed. In order to solve the problem that the cylindrical structure is not convenient for installing the ceiling, a third shed is also included, which is connected to the second shed and is used to cover the radiator.

[0016] In this solution, a third shelf is arranged on the second shelf, and the radiator is shielded by the third shelf. The second shelf is used as the installation position of the third shelf, which can facilitate the installation of the third shelf.

[0017] The Chinese-style box transformer is usually assembled in the factory and then transported to the construction site for installation. The third shelf is suspended on the upper side of the radiator. In order to solve the problem of vibration and deformation of the third shelf during transportation, the second shelf is provided with a rotating part. The third shelf is rotatably connected to the second shelf through the rotating part, and one end of the third shelf rotates between the upper side of the radiator and the upper side of the second shelf.

[0018] In this solution, the second shed is provided with a rotating part, so that the third shed can rotate relative to the second shed. Therefore, before the Chinese-style box-type transformer is transported to the construction site, the third shed can be rotated to the upper side of the second shed, so that the bottom of the third shed is supported by the second shed, so as to avoid the third shed from being suspended during transportation, thereby avoiding vibration damage to the third shed during transportation. After the Chinese-style box-type transformer is transported to the construction site, the third shed can be rotated to the upper side of the radiator, so that the third shed plays a protective role.

[0019] In order to solve the problem of the third shed body rotating randomly, a locking structure is further provided between the second shed body and the third shed body, and the locking structure is used to fix the position of the third shed body.

[0020] In this solution, the third shed body can be fixed by a locking structure to prevent the third shed body from rotating at will.

[0021] Preferably, the locking structure is used to fix the third shelf body at the first fixed position or the second fixed position. When the third shelf body is in the first fixed position, the third shelf body is located on the upper side of the second shelf body. When the third shelf body is in the second fixed position, one end of the third shelf body is located on the upper side of the radiator.

[0022] In this solution, if the Hua-style box-type transformer is in the process of transportation, the third shelf is fixed at the first fixed position to prevent the third shelf from rotating at will during transportation. After the Hua-style box-type transformer is installed, the third shelf can be fixed at the second fixed position to stably place the third shelf on the top of the radiator to prevent the third shelf from rotating to other positions.

[0023] Preferably, the locking structure includes a locking bolt, the second shelf body is provided with a locking screw hole, the third shelf body is provided with a through hole, and when the third shelf body is located at the first fixed position or the second fixed position, the second shelf body is respectively provided with a locking screw hole coaxial with the through hole.

[0024] In this solution, the position of the third shelf is fixed by locking bolts, which makes it easy to control the cost of the locking structure and also makes it easy to disassemble and assemble the locking structure.

[0025] Beneficial effects of the utility model:

[0026] The utility model provides a ceiling on the top of the Chinese-style box-type transformer, which blocks ice cubes falling from the fan and prevents the ice cubes from directly hitting the Chinese-style box-type transformer, thereby solving the problem that the Chinese-style box-type transformer is easily damaged by ice cubes.

[0035] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0036] Embodiment 1:

[0037] like Figure 1 As shown, the first embodiment provides a top-protected Chinese-style box transformer, including a box body 1, a radiator 2 and a ceiling 4, wherein the ceiling 4 is installed on the top of the box body 1 and the radiator 2 to shield ice cubes falling from the upper side.

[0038] The ceiling 4 can be formed by combining a plate and a profile. For example, a rectangular frame is constructed by using profiles, and the plate is fixed on the top of the rectangular frame to form the ceiling 4. The profiles are connected by fasteners or welded to form a rectangular frame, and the plate is fixed to the rectangular frame by fasteners or welding.

[0039] The box 1 and the radiator 2 may be provided with pillars 3, respectively, and connected to the ceiling 4 through the pillars 3. For example, a vertical profile is welded on the top of the box 1, and the vertically arranged profile serves as the pillar 3, and the top of the pillar 3 is connected to the ceiling 4. A plurality of pillars 3 are provided on the top of the box 1, and the plurality of pillars 3 are respectively provided at the edge of the top of the box 1, so as to facilitate the welding operation. The top of the pillar 3 and the ceiling 4 may be connected by fasteners or welding.

[0040] Providing the support pillars 3 can increase the distance between the ceiling 4 and the box body 1 and the radiator 2, so as to prevent the box body 1 or the radiator 2 from being squeezed when the ceiling 4 is deformed downward by being hit by ice cubes.

[0041] Similarly, the radiator 2 may also be welded with the support 3, and the radiator 2 and the support 3 on the top of the box 1 are connected to the ceiling 4 to fix the ceiling 4. It should be noted that the radiator 2 is provided with a bracket 22 for the heat sink 21, and the top of the bracket 22 for mounting the heat sink 21 is flat, and the support 3 is welded to the top of the bracket 22.

[0042] Embodiment 2:

[0043] The second embodiment provides a top-protected Chinese-style box-type transformer. The difference from the first embodiment is that the radiator 2 and the box body 1 in the second embodiment respectively use different ceilings 4.

[0044] like Figure 2 As shown, the ceiling 4 in the second embodiment includes a first shelf 41, a second shelf 42 and a third shelf 43, wherein the first shelf 41 is installed on the top of the radiator 2, specifically, is arranged on the top of the bracket 22 for installing the heat sink 21. The second shelf 42 is arranged on the top of the box 1. The first shelf 41 is used to protect the top of the radiator 2, and the second shelf 42 is used to protect the box 1.

[0045] Since the height of the radiator 2 is lower than that of the box 1, if the radiator 2 and the box 1 use the same ceiling 4, the bracket 22 on the upper side of the radiator 2 will be very long, and the material cost will be high. In addition, the heat sink 21 of the radiator 2 is far away from the box 1, and the structure between the heat sink 21 of the radiator 2 and the box 1 is irregular in shape, making it difficult to weld the pillars 3, and the ceiling 4 cannot be effectively supported. Therefore, in the second embodiment, a first shelf 41 and a second shelf 42 are respectively set on the top of the radiator 2 and the box 1.

[0046] The fixing method of the second shelf body 42 is the same as the fixing method of the ceiling 4 in the first embodiment.

[0047] The first shelf 41 is fixed to the top of the bracket 22 for mounting the heat sink 21 in another fixing manner.

[0048] like Figure 3 As shown, a plurality of mounting ear plates 6 are arranged on the top of the bracket 22 for mounting the heat sink 21, and the plurality of mounting ear plates 6 are arranged in rows. That is to say, the plurality of mounting ear plates 6 can be arranged in several rows. For example, the plurality of mounting ear plates 6 can be arranged in two rows, three rows or more. Each row of mounting ear plates 6 is connected to a connecting piece 7, and the mounting ear plates 6 and the connecting piece 7 are both provided with holes. The connecting piece 7 and the mounting ear plates 6 can be connected with fasteners such as bolts. The first shed body 41 is connected to the connecting piece 7. When the first shed body 41 is subjected to force, the force can be transmitted to each mounting ear plate 6 through the connecting piece 7, so as to avoid the mounting ear plates 6 being damaged due to excessive concentrated force.

[0049] The connecting member 7 is preferably an angle steel. During installation, one surface of the angle steel is in a vertical state, and the surface in the vertical state is connected to the mounting lug plate 6. The other surface of the angle steel is in a horizontal state, and the surface in the horizontal state is connected to the first shelf body 41.

[0050] The first shelf 41 and the connecting member 7 can be indirectly connected through the fixing member 8, and a plurality of fixing members 8 are arranged on the connecting member 7, the bottoms of the plurality of fixing members 8 are connected to the connecting member 7, and the tops of the plurality of fixing members 8 are connected to the first shelf 41. The fixing members 8 can increase the distance between the first shelf 41 and the radiator 2, thereby increasing the space between the first shelf 41 and the radiator 2, and facilitating the installation operation.

[0051] The fixing member 8 is made of channel steel, and since the connecting member 7 serves to connect the mounting lugs 6, a short section of channel steel can be used as the fixing member 8. In other words, angle steel is used as the connecting member 7 to connect the mounting lugs 6, and then channel steel is used as the fixing member 8 to connect the first shelf body 41. This arrangement can reduce the length of the channel steel used and reduce costs.

[0052] The third shed 43 is installed on the top of the second shed 42, and is used to shield the radiator 2. The first shed 41 is used to shield the fins 21 of the radiator 2, and the third shed 43 is used to shield the other parts of the radiator 2 except the fins 21.

[0053] The third shelf 43 can be fixed to the second shelf 42 by fasteners such as bolts. The reason for setting a separate third shelf 43 is that there is a high cylinder part in the radiator 2, the height of the cylinder part is higher than the box 1, and the distance between the cylinder part and the heat sink 21 is far, and the top of the cylinder part is not flat, which is not convenient for installing the support 3, and it is not convenient to cover the cylinder part by the first shelf 41. Therefore, the third shelf 43 is fixed to the top of the second shelf 42, and there is no need to increase the height of the second shelf 42 to cover the cylinder part, and the height of the third shelf 43 only needs to be higher than the cylinder part.

[0054] Embodiment three:

[0055] This embodiment 3 provides a top-protected Chinese-style box-type transformer, such as Figure 3 As shown, based on the second embodiment, a rotating part 5 is provided on the top of the second shelf 42 in the third embodiment, and the third shelf 43 is connected to the second shelf 42 through the rotating part 5, so that the third shelf 43 can be rotated from the upper side of the second shelf 42 to the upper side of the radiator 2.

[0056] Specifically, one end of the third shelf 43 is connected to the rotating part 5 , and when the third shelf 43 rotates, the other end of the third shelf 43 can rotate from the upper side of the second shelf 42 to the upper side of the radiator 2 .

[0057] The second shelf body 42 is provided with a locking screw hole 10, and the third shelf body 43 is provided with a through hole. As the third shelf body 43 rotates, when the third shelf body 43 is in a position, the through hole and the screw hole are coaxial. When the through hole on the third shelf body 43 and the screw hole on the second shelf body 42 are coaxial, a locking bolt 9 can be passed through the through hole and connected to the locking screw hole 10, so that the third shelf body 43 can be fixed to prevent the third shelf body 43 from rotating.

[0058] Two locking screw holes 10 are provided on the second shelf 42. When the third shelf 43 is completely on the upper side of the second shelf 42, the through hole is coaxial with one locking screw hole 10, and the third shelf 43 can be fixed by the locking bolt 9 at this time, and the third shelf 43 is in the first fixed position. When one side of the third shelf 43 is rotated onto the radiator 2, the through hole on the third shelf 43 is coaxial with the other locking screw hole 10, and the locking bolt 9 can be used to fix the third shelf 43 again at this time, and the third shelf 43 is in the second working position.

[0059] During the transportation of the Chinese-style box-type transformer, the third shelf 43 is in the first working position. When the Chinese-style box-type transformer is installed, the third shelf 43 is rotated to the second working position. When the third shelf 43 is in the second working position, one end of the third shelf 43 is connected to the rotating part 5, and the other end of the third shelf 43 is in a suspended state.

[0060] It should be noted that the third shelf 43 and the first shelf 41 complement each other and jointly shield the radiator 2. The third shelf 43 and the first shelf 41 may have an overlapping area to ensure that the first shelf 41 and the second shelf 42 can shield ice cubes falling from above.

[0061] The locking bolt 9 is used as a locking structure for fixing the third shelf body 43. The locking structure can also be replaced by a locking pin or other structure. When the locking structure is a locking pin, the locking screw hole 10 is replaced by a pin hole.

[0062] The rotating part 5 may be a bearing, and the second shelf body 42 and the third shelf body 43 are respectively connected to the outer ring and the inner ring of the bearing, so that the third shelf body 43 can rotate relative to the second shelf body 42.

[0063] like Figure 5 As shown, the rotating part 5 can also be a rotating shaft, which is welded to the top of the second shed body 42, and a rotating hole adapted for the rotating shaft is set on the third shed body 43. The rotating shaft passes through the rotating hole, and the third shed body 43 can also rotate relative to the second shed body 42.
