Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective structure technology, and in particular to a transformer coil protective structure. Background Technology
[0002] The protective structure is used to protect the transformer coil during transportation. The protective structure consists of a pair of semi-circular protective shells. When using the protective structure, the transformer coil is placed inside one semi-circular protective shell, and then the other semi-circular protective shell is fastened on, thereby preventing damage to the transformer coil during transportation.
[0003] In their daily work, the inventors discovered that when the protective structure is in use, since a pair of semi-circular protective shells are generally fixed by a locking block and a locking slot, the fixing method is relatively simple. When the transport vehicle encounters a bumpy road section, the locking block and the locking slot can easily separate, causing the semi-circular protective shells to separate from each other, which may cause the transformer to be thrown out and damaged. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in actual use, a pair of semi-circular protective shells are generally fixed by a locking block and a locking groove, which is a relatively simple fixing method. When the transport vehicle encounters a bumpy road section, the locking block and the locking groove can easily separate, causing the semi-circular protective shells to separate from each other, which may cause the transformer to be shaken out and damaged. Therefore, a transformer coil protection structure is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a transformer coil protection structure, comprising a pair of semi-circular protective shells, wherein a fixing component and a connecting component are provided on the arc surface of the semi-circular protective shell, a rubber protective pad is fixedly connected to the inner wall of the semi-circular protective shell, a locking block is fixedly connected to the lower end of the upper semi-circular protective shell, and a locking groove is opened at the upper end of the lower semi-circular protective shell. The fixing component includes multiple evenly distributed pins that slide and insert into the arc surface of the locking block, a first spring is fixedly connected between the pins and the locking block, a sliding surface is opened at the left end of the pin, and multiple evenly distributed locking holes are opened on the inner wall of the locking groove.
[0006] The effect achieved by the above components is as follows: by setting the fixing components, after the transformer coil is placed inside the semi-circular protective shell, the worker will fasten the other half of the semi-circular protective shell into the semi-circular protective shell, so that the locking block is inserted into the locking groove, and the pin is inserted into the locking hole by means of the sliding surface and the first spring, thereby fixing the two semi-circular protective shells, and thus achieving the best possible fixation between the semi-circular protective shells.
[0007] Preferably, an L-shaped rod is slidably connected to the inner wall of the semi-circular protective shell, and a pull rope is fixedly connected between the L-shaped rod and the pin, the pull rope passing through the locking block.
[0008] The effect achieved by the above components is as follows: after the pin is inserted into the locking hole, the L-shaped rod is moved downward to contact the pin. Then, the L-shaped rod is limited by the fixing mechanism to prevent the first spring from shaking during bumps, which could cause the pin to separate from the locking hole. The L-shaped rod moves upward, which drives the pull rope to retract the pin into the locking block, thereby disassembling the two semi-circular protective shells.
[0009] Preferably, the semi-circular protective shell has a sliding ring slidably connected to its arc surface, and the sliding ring and the L-shaped rod are fixed together.
[0010] The effect achieved by the above components is to drag the slip ring downwards, thereby moving the L-shaped rod downwards.
[0011] Preferably, the slip ring has a screw threaded into its arc-shaped surface, and the screw is threadedly connected to the semi-circular protective shell.
[0012] The aforementioned components achieve the following effects: by tightening the screws, they are threadedly fixed to the semi-circular protective shell, thus fixing the slip ring and limiting the L-shaped rod.
[0013] Preferably, one end of the screw is fixedly connected to a second spring, and the other end of the second spring is slidably connected to a slip ring.
[0014] The effect achieved by the above components is as follows: by setting a second spring, when the screw is turned, the second spring deforms, pushing the screw outward, so that the screw fits into the threaded groove inside the semi-circular protective shell, thereby preventing the screw from loosening due to bumps as much as possible.
[0015] Preferably, the connecting assembly includes a positioning block fixedly connected to the arc surface of the lower semi-circular protective shell, and an insert block fixedly connected to the arc surface of the upper semi-circular protective shell, the insert block being inserted into the positioning block.
[0016] The effect achieved by the above components is as follows: when connecting two semi-circular protective shells, the worker drags the upper semi-circular protective shell downwards, so that the insert block is inserted into the positioning block. Then, through the positioning mechanism, the insert block and the positioning block are fixed together, thereby achieving the connection and fixation of the two semi-circular protective shells as much as possible.
[0017] Preferably, the positioning block has an insert rod inserted into its arc surface, and the insert rod is inserted into the insert block.
[0018] The effect achieved by the above components is that the insert rod is inserted into the insert block, and the surface of the insert rod has a protrusion, which fixes the insert block and the positioning block.
[0019] Preferably, one end of the insertion rod is fixedly connected to a third spring, and the other end of the third spring is fixed to the positioning block.
[0020] The effect achieved by the above components is that by setting a third spring, the third spring pulls the insertion rod, thereby assisting in limiting the insertion rod.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting a fixing component, after the transformer coil is placed inside the semi-circular protective shell, the worker fastens the other half of the semi-circular protective shell into the semi-circular protective shell, so that the locking block is engaged in the locking groove, and the pin is engaged in the locking hole by means of the sliding surface and the first spring, thereby fixing the two semi-circular protective shells. This achieves better fixation between the semi-circular protective shells and solves the problem that since a pair of semi-circular protective shells are generally fixed by locking blocks and locking grooves, the fixing method is relatively simple. However, when the transport vehicle encounters bumpy road sections, the locking blocks and locking grooves can easily separate, causing the semi-circular protective shells to separate from each other, which may cause the transformer to be shaken out and damaged.

Detailed Implementation
[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a transformer coil protection structure includes a pair of semi-circular protective shells 1. The arc surface of the semi-circular protective shell 1 is provided with a fixing component 2 and a connecting component 3. The inner wall of the semi-circular protective shell 1 is fixedly connected with a rubber protective pad 4. The lower end of the upper semi-circular protective shell 1 is fixedly connected with a locking block 5, and the upper end of the lower semi-circular protective shell 1 is provided with a locking groove 6.
[0029] The following section will explain the specific settings and functions of the fixing component 2 and the connecting component 3.
[0030] Reference Figure 2 and Figure 4 As shown, in this embodiment: the fixing component 2 includes multiple evenly distributed pins 21 on the arc surface of the sliding insertion block 5. A first spring 23 is fixedly connected between the pins 21 and the block 5. A sliding surface 24 is provided at the left end of the pin 21. Multiple evenly distributed locking holes 22 are provided on the inner wall of the locking groove 6. By setting the fixing component 2, after the transformer coil is placed into the semi-circular protective shell 1, the worker will fasten the other half of the semi-circular protective shell 1 into the semi-circular protective shell 1, so that the locking block 5 is inserted into the locking groove 6, thus allowing the insertion... Pin 21, with the aid of sliding surface 24 and first spring 23, is engaged in the locking hole 22, thereby fixing the two semi-circular protective shells 1 and achieving better fixation between them. An L-shaped rod 25 is slidably connected to the inner wall of each semi-circular protective shell 1. A pull rope 27 is fixedly connected between the L-shaped rod 25 and the pin 21, passing through the locking block 5. After the pin 21 is inserted into the locking hole 22, the L-shaped rod 25 is moved downwards until it contacts the pin 21. Then, the fixing mechanism secures the L-shaped rod... The L-shaped rod 25 is positioned to prevent the first spring 23 from shaking during bumps, which could cause the pin 21 to separate from the locking hole 22. The upward movement of the L-shaped rod 25 drives the pull rope 27, causing the pin 21 to retract into the locking block 5, thereby disassembling the two semi-circular protective shells 1. A slip ring 26 is slidably connected to the arc surface of each semi-circular protective shell 1. The slip ring 26 is fixed to the L-shaped rod 25. Dragging the slip ring 26 downwards moves the L-shaped rod 25 downwards. A screw 28 is threaded into the arc surface of the slip ring 26, and the screw 28 is screwed into the semi-circular protective shell 1. The screw 28 is threaded and tightened to fix it to the semi-circular protective shell 1, thereby fixing the slip ring 26 and limiting the L-shaped rod 25. One end of the screw 28 is fixedly connected to a second spring 29, and the other end of the second spring 29 is slidably connected to the slip ring 26. By setting the second spring 29, after the screw 28 is tightened, the second spring 29 deforms, pushing the screw 28 outward, so that the screw 28 fits into the threaded groove in the semi-circular protective shell 1, thereby preventing the screw 28 from loosening due to bumps as much as possible.
[0031] Reference Figure 3As shown in this embodiment: the connecting component 3 includes a positioning block 31 fixedly connected to the arc surface of the lower semi-circular protective shell 1, and an insert block 32 fixedly connected to the arc surface of the upper semi-circular protective shell 1. The insert block 32 is inserted into the positioning block 31. When connecting the two semi-circular protective shells 1, the worker drags the upper semi-circular protective shell 1 downwards, so that the insert block 32 is inserted into the positioning block 31. Then, the positioning mechanism fixes the insert block 32 and the positioning block 31, thereby achieving the connection and fixation of the two semi-circular protective shells 1 as much as possible. An insert rod 33 is inserted into the arc surface of the positioning block 31. The insert rod 33 is inserted into the insert block 32. The insert rod 33 has a protrusion on its surface, which fixes the insert block 32 and the positioning block 31. One end of the insert rod 33 is fixedly connected to a third spring 34. The other end of the third spring 34 is fixed to the positioning block 31. By setting the third spring 34, the third spring 34 pulls the insert rod 33, thereby limiting the insertion rod 33.
[0032] Working principle:
[0033] When using the protective structure, the transformer coil is placed inside a semi-circular protective shell 1, and then another semi-circular protective shell 1 is fastened on top. This prevents damage to the transformer coil during transport by the transport vehicle. Simultaneously, the rubber protective pad 4 cushions the transformer coil and the semi-circular protective shell 1. After placing the transformer coil inside the semi-circular protective shell 1, the worker fastens the other semi-circular protective shell 1, causing the locking block 5 to engage with the locking groove 6. This allows the pin 21 to engage with the locking hole 22 via the sliding surface 24 and the first spring 23, thus securing the two semi-circular protective shells 1 and achieving optimal fixation between them. After the pin 21 is in the locking hole 22, the sliding ring 26 is dragged downwards, causing the L-shaped rod 25 to move downwards and contact the pin 21. Then, the screw 28 is tightened to thread it onto the semi-circular protective shell 1, fixing the sliding ring 26 and limiting the L-shaped rod 25. To prevent the first spring 23 from shaking during bumps, which could cause the pin 21 to separate from the locking hole 22, the L-shaped rod 25 moves upward, driving the pull rope 27 to retract the pin 21 into the locking block 5, thereby disassembling the two semi-circular protective shells 1. By setting a second spring 29, after the screw 28 is turned, the second spring 29 deforms, pushing the screw 28 outward, so that the screw 28 fits into the threaded groove in the semi-circular protective shell 1, thus preventing the screw 28 from loosening due to bumps as much as possible. When connecting the two semi-circular protective shells 1, the worker drags the upper semi-circular protective shell 1 downward, so that the insert block 32 is locked into the positioning block 31, and then inserts the insert rod 33 into the insert block 32. The insert rod 33 has a protrusion on its surface, which fixes the insert block 32 and the positioning block 31, thereby achieving as much connection and fixation as possible for the two semi-circular protective shells 1. By setting a third spring 34, the third spring 34 pulls the insert rod 33, thus providing auxiliary limit for the insert rod 33.
