Description

Technical Field

[0001] This utility model relates to the field of box-type transformer technology, and specifically to a protective structure. Background Technology

[0002] In existing technologies, box-type transformers are usually installed in outdoor environments, such as photovoltaic power stations, wind farms, or charging stations. They may face the risk of falling objects from heights (such as tree branches, hail, construction debris, etc.) or accidental collisions. If the heat sink of the box-type transformer is exposed, it may cause transformer oil leakage if it is impacted, leading to serious accidents. In environments such as wind farms, box-type transformers may face the impact of strong winds carrying debris (such as sand, gravel, and metal fragments). Therefore, some manufacturers will add additional protective steel plates or mesh structures to enhance protection. Protective nets can reduce the direct damage of such foreign objects to the equipment.

[0003] However, foreign objects often get stuck or caught in the mesh of the protective netting, making manual cleaning very difficult. As the usage time increases, the amount of foreign objects accumulates, and long-term accumulation of foreign objects leads to deformation or accelerated corrosion of the ceiling.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a protective structure to solve the technical problems of foreign matter accumulation and difficulty in cleaning foreign matter in the protective structure of box-type transformers in related technologies.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a protective structure is provided, comprising: a box body, the inside of which contains the object to be protected, and a protective net covering the outer surface of the box body; a collection device, which is installed on the top of the box body, the collection device comprising a protective plate extending along a first preset direction and a collection mechanism disposed below the protective plate, the protective plate being rotatably disposed around the first preset direction, the collection mechanism being used to collect foreign objects falling when the protective plate is rotatably disposed, and the collection device comprising a first return spring connected to the protective plate, the first return spring being kept in a stretched state.

[0007] Furthermore, the collection mechanism includes a first collection plate disposed below the protective plate, which is used to catch foreign objects that fall when the protective plate is flipped over.

[0008] Furthermore, the collection mechanism includes a support frame, on which a rotating shaft is mounted, through which a first collection plate passes, and on which a second return spring is mounted. The second return spring is kept in a stretched state and is centrally located below the first collection plate. The second return spring is connected to both the first collection plate and the support frame.

[0009] Furthermore, the protective plates include multiple plates, which are spaced apart along the extension direction of the first collecting plate.

[0010] Furthermore, a protective plate support frame is provided on the side of the first collection plate. The protective plate support frame has a channel for foreign objects to pass through. Multiple protective plates are movably installed on the protective plate support frame. The protective plate support frame includes two frames, which are respectively located on both sides of the first collection plate.

[0011] Furthermore, the first reset spring is centrally located below the protective plate, and is connected to both the protective plate and the first collecting plate.

[0012] Furthermore, the collection mechanism includes a second collection plate disposed below the first collection plate. The second collection plate is used to catch foreign objects that fall when the first collection plate is flipped. There are two second collection plates, which are respectively disposed on both sides of the first collection plate.

[0013] Furthermore, the second collecting plate is inclined along the extension direction of the first collecting plate.

[0014] Furthermore, the protective plate has mesh openings, and the mesh openings are multiple, arranged in a rectangular array on the protective plate.

[0015] Furthermore, the collection device includes multiple collection devices, which are spaced apart along the extension direction of the ceiling.

[0016] Beneficial effects: 1. In the protective structure of this embodiment, when the protective plate is in its normal position, it can block foreign objects falling on it, preventing them from entering the housing, thus forming the first level of protection. The protective plate can be flipped around a first preset direction. When a foreign object falls on the protective plate, it can be shaken off by flipping, preventing the foreign object from accumulating on the protective plate for a long time. The collection device is equipped with a special collection mechanism for collecting foreign objects falling from the protective plate. This ensures that the foreign objects will not scatter randomly after being shaken off, but will be collected by the collection device for easy subsequent cleaning. The first return spring remains in a stretched state. After the protective plate is flipped, it can automatically return to its initial position through the action of the first return spring. This not only improves the convenience of operation, but also ensures that the protective plate can continuously and effectively block foreign objects, and facilitates quick restoration of the protective state after cleaning the foreign objects. This protective structure effectively reduces the entry of foreign objects through the blocking effect of the protective net and the protective plate. At the same time, the design of the collection mechanism and the first return spring allows the foreign objects to be collected in a concentrated manner and easily cleaned, solving the technical problems of foreign object accumulation and difficulty in cleaning foreign objects in the protective structure of box-type transformers in related technologies.

[0017] 2. A first collection plate is installed to catch foreign objects falling when the protective plate is flipped, thus achieving a second level of protection. The first collection plate has a rotating function. When a certain amount of foreign objects accumulate on the first collection plate, the first collection plate flips, causing the foreign objects to fall off the first collection plate and preventing them from accumulating on it.

[0018] 3. By setting up a second collection plate to catch foreign objects falling when the first collection plate is flipped, a third level of protection is formed. The two second collection plates are respectively set on both sides of the first collection plate. No matter which direction the first collection plate is flipped, the foreign objects can be collected by the second collection plate. Attached Figure Description

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] According to an embodiment of this utility model, a protective structure is provided; please refer to [link / reference]. Figures 1 to 5The device includes: a housing 10, which contains the object to be protected and has a protective net covering its outer surface; and a collection device 20, which is installed on the roof of the housing 10. The collection device 20 includes a protective plate 1 extending along a first preset direction and a collection mechanism disposed below the protective plate 1. The protective plate 1 is rotatably arranged around the first preset direction. The collection mechanism is used to collect foreign objects that fall when the protective plate 1 is rotatably arranged. The collection device 20 includes a first return spring 2 connected to the protective plate 1 and the first return spring 2 is kept in a stretched state.

[0023] In the protective structure of this embodiment, when the protective plate 1 is in its normal position, it can block foreign objects falling on it and prevent them from entering the housing 10, thus forming the first level of protection. The protective plate 1 can be flipped around a first preset direction. When a foreign object falls on the protective plate 1, it can be shaken off by flipping, preventing the foreign object from accumulating on the protective plate 1 for a long time. The collection device 20 is equipped with a collection mechanism specifically for collecting foreign objects falling from the protective plate 1. This ensures that the foreign objects will not scatter randomly after being shaken off, but will be collected by the collection device 20 for easy subsequent cleaning. The first return spring 2 is kept in a stretched state. After the protective plate 1 is flipped, it can automatically return to its initial position by the action of the first return spring 2. This not only improves the convenience of operation, but also ensures that the protective plate 1 can continuously and effectively block foreign objects, and at the same time, it is convenient to quickly restore the protective state after cleaning the foreign objects. This protective structure effectively reduces the entry of foreign objects through the blocking effect of the protective net and the protective plate. At the same time, the design of the collection mechanism and the first return spring 2 enables the foreign objects to be collected and easily cleaned, solving the technical problems of foreign object accumulation and difficulty in cleaning in the protective structure of box-type transformers in related technologies.

[0024] In the protective structure of this embodiment, see Figure 2 The collection mechanism includes a first collection plate 3 disposed below the protective plate 1, which is used to collect foreign objects that fall when the protective plate 1 is flipped. By setting the first collection plate 3 to collect foreign objects that fall when the protective plate 1 is flipped, a second level of protection is achieved.

[0025] In the protective structure of this embodiment, see Figure 2-3 The collection mechanism includes a support frame 4, on which a rotating shaft is mounted. A first collection plate 3 passes through the rotating shaft. A second return spring 5 is mounted on the support frame 4 and remains in a stretched state. The second return spring 5 is centrally located below the first collection plate 3 and is connected to both the first collection plate 3 and the support frame 4. The support frame 4 supports the first collection plate 3, enabling it to rotate. When a certain amount of foreign matter accumulates on the first collection plate 3, the plate flips, causing the foreign matter to fall off and preventing it from accumulating on the plate.

[0026] By setting a second reset spring 5, when the first collecting plate 3 flips, it is reset by the second reset spring 5, so that the first collecting plate 3 returns to a horizontal state and continues to receive foreign objects falling from the protective plate 1.

[0027] It is understandable that some larger foreign objects may not be able to fall through the protective plate 1 onto the first collection plate 3. These larger foreign objects will accumulate on the protective plate 1. When the first collection plate 3 rotates, the protective plate 1 will also flip at the same time, and the larger foreign objects accumulated on the protective plate 1 and the first collection plate 3 can fall off at the same time.

[0028] In the protective structure of this embodiment, see Figure 2 The protective plate 1 includes multiple plates, which are spaced apart along the extension direction of the first collection plate 3. By setting multiple protective plates 1, which are sensitive and compact, the flexibility and sensitivity of the protective plates 1 can be improved. Even relatively small foreign objects can cause the protective plates 1 to flip over, thereby improving the cleaning efficiency of foreign objects.

[0029] In the protective structure of this embodiment, see Figure 2 A protective plate support frame 31 is provided on the side of the first collection plate 3. The protective plate support frame 31 has a channel 32 for foreign objects to pass through. Multiple protective plates 1 are movably mounted on the protective plate support frame 31. There are two protective plate support frames 31, one on each side of the first collection plate 3. By providing the protective plate support frame 31 to support the multiple protective plates 1, the multiple protective plates 1 can be rotated. The channel 32 allows foreign objects on the first collection plate 3 to pass through the channel 32 and leave the first collection plate 3 to the next stage collection mechanism.

[0030] In the protective structure of this embodiment, see Figure 3 or Figure 5 The first return spring 2 is centrally located below the protective plate 1, and is connected to both the protective plate 1 and the first collecting plate 3. Centralizing the first return spring 2 ensures that the protective plate 1 can be returned to a horizontal state regardless of whether it is tilted in any direction.

[0031] In the protective structure of this embodiment, see Figure 3 The collection mechanism includes a second collection plate 6 disposed below the first collection plate 3. The second collection plate 6 is used to catch foreign objects falling when the first collection plate 3 is flipped. There are two second collection plates 6, which are respectively disposed on both sides of the first collection plate 3. By setting the second collection plates 6 to catch foreign objects falling when the first collection plate 3 is flipped, a third level of protection is formed. Since the two second collection plates 6 are respectively disposed on both sides of the first collection plate 3, foreign objects can be collected by the second collection plates 6 no matter which direction the first collection plate 3 is flipped.

[0032] In the protective structure of this embodiment, see Figure 2 The second collection plate 6 is inclined along the extension direction of the first collection plate 3. By inclining the second collection plate 6, foreign objects on the second collection plate 6 can slide down along the second collection plate 6, thereby achieving automatic cleaning, reducing the frequency of manual cleaning, and further avoiding the problems of foreign object accumulation and difficulty in cleaning.

[0033] In the protective structure of this embodiment, see Figure 2 The protective plate 1 has multiple mesh openings arranged in a rectangular array. In this way, smaller foreign objects can fall through the mesh openings onto the first collection plate 3, while relatively larger foreign objects fall onto the first collection plate 3 by flipping the protective plate 1. Even larger foreign objects are collected by flipping the protective plate 1 when the first collection plate 3 rotates.

[0034] Understandably, the mesh openings on the protective plate 1 ensure that the interior of the protective structure is breathable, thus guaranteeing the heat dissipation and ventilation effects for protective components such as transformers.

[0035] In the protective structure of this embodiment, see Figure 1 The collection device 20 includes multiple devices, which are spaced apart along the extension direction of the ceiling. By spaced out multiple collection devices 20 along the extension direction of the ceiling, the distribution of foreign objects on the ceiling is more uniform, providing more comprehensive coverage of the ceiling area of ​​the enclosure 10 and avoiding blind spots. Any foreign objects falling on the ceiling can be promptly captured and processed by the corresponding collection device, preventing accumulation due to insufficient local protection and reducing the possibility of long-term accumulation of foreign objects in certain areas.

[0036] In some embodiments, the enclosure 10 is provided with a door for maintenance personnel to enter the interior of the enclosure 10, and an oil drain port for maintenance of the transformer is also provided to facilitate maintenance of the transformer from the outside of the enclosure 10.

[0037] Applying the protective structure of this embodiment to the protection of a box-type transformer, when a foreign object falls onto the protective plate 1, and when the foreign object accumulates to a certain level or is triggered externally, the protective plate 1 will flip around a first preset direction, shaking the foreign object onto the first collecting plate 3. After flipping, the protective plate 1 automatically returns to its initial position through the action of the first return spring 2, continuing to provide protection. The first collecting plate 3 receives the foreign object falling from the protective plate 1. When the foreign object accumulates to a certain amount on the first collecting plate 3, the first collecting plate 3 will flip, causing the foreign object to fall off. After flipping, the second return spring 5 restores the first collecting plate 3 to a horizontal state, ready to receive foreign objects again. The second collecting plate 6 is disposed on both sides of the first collecting plate 3 to receive foreign objects falling when the first collecting plate 3 flips, forming a third level of protection. Because the second collection plate 6 is inclined, foreign objects can slide down the inclined surface to achieve automatic cleaning. The protective structure of this embodiment forms a multi-level protection and foreign object cleaning process, which not only effectively reduces the entry of foreign objects into the box and avoids damage to the box transformer, but also simplifies the collection and cleaning process of foreign objects through an automated mechanism, solving the technical problems of foreign object accumulation and difficulty in cleaning foreign objects in the protective structure of box transformers in related technologies.
