Description

Technical Field

[0001] This utility model relates to the field of switch protection technology, and specifically to a switch protection device. Background Technology

[0002] Photovoltaic power generation, as an innovative form of power generation, is based on the photovoltaic effect of semiconductor materials in batteries, which enables the direct and efficient conversion of solar radiation energy into electrical energy, opening up new avenues for energy utilization.

[0003] In the entire photovoltaic power plant system, the photovoltaic inverter occupies a central position, playing a crucial role in the stable output and efficient conversion of electrical energy. However, during routine operation and maintenance, the start-up and shutdown switches of the photovoltaic inverter are directly exposed to the external environment, increasing the risk of accidental contact. Once an accidental contact occurs, it is highly likely to cause equipment failure and shutdown, which will not only directly affect power generation and cause energy waste, but also disrupt the power quality of the grid, resulting in damage to the power plant's efficiency.

[0004] Traditional switch protection devices consist of a hinged base and a top cover. When the base and top cover are fastened together, they surround the switch, preventing it from being directly exposed to the outside when not in use. However, they occupy a large amount of vertical space. In some photovoltaic power plants with compact layouts, they are prone to spatial conflicts with other equipment, which not only makes the installation and layout of other equipment difficult, but may also affect the normal operation of other equipment.

[0014] In one alternative embodiment, a connecting structure is further included, wherein the rotating end is connected to one of the fourth side plates; the connecting structure is disposed opposite to the rotating end in a second direction and is adapted to connect the protective cover and the base.

[0015] Beneficial effect: By setting the connecting structure opposite to the rotating end in the second direction, it helps to achieve the connection between the protective cover and the base without affecting the rotation of the rotating end.

[0016] In one optional embodiment, the connection structure includes a first connecting plate and a second connecting plate; the first connecting plate is disposed on a second side plate away from the rotating end, one end of which is connected to the end of the second side plate opposite to the first side plate, and the other end extends along a second direction; the second connecting plate is disposed on a fourth side plate away from the rotating end, one end of which is connected to the end of the fourth side plate opposite to the third side plate, and the other end extends along a second direction; and the second connecting plate and the first connecting plate are detachably connected.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, a switch protection device is provided, including a base and a protective cover; the base is provided with a first protective groove, and the bottom of the first protective groove is provided with an installation port 11; along a first direction, the bottom of the groove of the base is fixed to a fixing back plate for fixing the switch, and the switch is adapted to pass through the installation port 11 and be located in the first protective groove; the protective cover includes a rotating end 21 and a closing end connected in sequence, the rotating end 21 is arranged adjacent to the base along a second direction and is rotatably connected to the fixing back plate, and the rotation axis of the protective cover extends along the first direction; the closing end has a first position to be rotated to close with the base and a second position to be rotated to separate from the base; the first direction is a direction perpendicular to the fixing back plate, and the second direction is perpendicular to the first direction.

[0038] The base and the fixed back plate of the switch are connected in the first direction, and the rotation axis of the protective cover extends along the first direction. Therefore, when the rotating end 21 of the protective cover rotates, the rotation plane of the closed end is always parallel to the fixed back plate. Only the angle adjustment in the plane is required, which effectively avoids the additional three-dimensional space occupation caused by the opening and closing of traditional devices. Under the premise of ensuring that the opening and closing function of the protective cover is not affected and the integrity is maintained, space compression in the first direction is achieved. It maintains the protective performance of the switch protection device for the switch, and achieves the dual goals of compact structure and complete function by optimizing the movement trajectory of the protective cover.

[0039] In a specific implementation, the switch protection device composed of the protective cover and the cover plate 221 has a hexagonal structure.

[0040] In one embodiment, the protective cover is provided with a second protective groove, which is disposed at the closed end of the cover and is disposed opposite to the first protective groove; when the protective cover is in the first position, the second protective groove and the first protective groove surround each other to form a protective cavity.

[0041] By setting a first protective groove and a second protective groove, when the protective cover closes with the base along a preset trajectory, the first protective groove and the second protective groove form a closed and independent protective cavity, which realizes the airtight protection of the switch and effectively isolates the interference of external environmental factors on the switch.

[0042] In one embodiment, the base includes a fixing plate 12, a first side plate 13, and two second side plates 14; the fixing plate 12 is fixed to the fixing back plate, and the mounting port 11 is disposed on the fixing plate 12; the first side plate 13 is located on one side of the protective cavity along a third direction and is connected to the fixing plate 12; the first direction, the second direction, and the third direction are perpendicular to each other; the two second side plates 14 are respectively connected to both sides of the first side plate 13 along a second direction and are both connected to the fixing plate 12; the fixing plate 12, the first side plate 13, and the two second side plates 14 enclose and form the first protective groove.

[0043] The connection between the base and the fixed back plate is achieved by setting the fixing plate 12; and the setting of the first side plate 13 and the second side plate 14 achieves partial protection of the switch in the third direction and the second direction.

[0044] In a specific implementation, the fixing plate 12 is fixed to the fixing back plate by screws or other fasteners. There is no limit to the number of screws or other fasteners. Multiple screws or other fasteners can be set, and the multiple fasteners are evenly arranged around the outer periphery of the switch to ensure the stability of the installation between the base and the fixing back plate.

[0045] In a specific implementation, the fixing plate 12 has a hexagonal structure.

[0046] In one embodiment, the closing end includes a cover plate 221, a third side plate 222, and two fourth side plates 223; the cover plate 221 is disposed opposite to the fixing plate 12 along a first direction; the third side plate 222 is located on the other side of the protective cavity along a third direction and is connected to the cover plate 221; the two fourth side plates 223 are respectively connected to both sides of the third side plate 222 along a second direction and are both connected to the cover plate 221; and the fourth side plates 223 and the adjacent second side plates 14 are arranged sequentially along the third direction and abut against each other; the cover plate 221, the third side plate 222, and the two fourth side plates 223 enclose and form the second protective groove.

[0047] By setting the cover plate 221 opposite to the fixing plate 12, the protective cover protects the switch in the first direction. By setting the third side plate 222 along the third direction on the other side of the protective cavity, the third side plate 222 and the first side plate 13 completely protect the switch in the third direction. Since the fourth side plate 223 is connected to the third side plate 222 and the second side plate 14 is connected to the first side plate 13, all-round protection of the switch is achieved. The fourth side plate 223 and the adjacent second side plate 14 are arranged sequentially along the third direction and abut against each other, thus completely protecting the switch in the second direction. Since the fourth side plate 223 is connected to the third side plate 222 and the second side plate 14 is connected to the first side plate 13, all-round protection of the switch is achieved.

[0048] In a specific implementation, the cover plate 221 has a hexagonal structure.

[0049] In one embodiment, a connecting structure is also included, wherein the rotating end 21 is connected to a fourth side plate 223; the connecting structure is disposed opposite to the rotating end 21 in a second direction and is adapted to connect the protective cover and the base.

[0050] By setting the connecting structure opposite to the rotating end 21 in the second direction, it is helpful to achieve the connection between the protective cover and the base without affecting the rotation of the rotating end 21.

[0051] In a specific embodiment, the rotating end 21 includes a connecting ear plate 211, which is connected to the fourth side plate 223 and is arranged perpendicular to the first direction. The connecting ear plate 211 is provided with a through hole 212, through which fasteners such as screws pass and are connected to the fixed back plate. This can realize the connection between the protective cover and the fixed back plate, as well as the relative rotation between the rotating end 21 and the fixed back plate.

[0052] In one embodiment, the connection structure includes a first connecting plate 31 and a second connecting plate 32; the first connecting plate 31 is disposed on a second side plate 14 away from the rotating end 21, one end of which is connected to the end of the second side plate 14 opposite to the first side plate 13, and the other end extends along a second direction; the second connecting plate 32 is disposed on a fourth side plate 223 away from the rotating end 21, one end of which is connected to the end of the fourth side plate 223 opposite to the third side plate 222, and the other end extends along a second direction; and the second connecting plate 32 and the first connecting plate 31 are detachably connected.

[0053] By providing a first connecting plate 31 and a second connecting plate 32 on the second side plate 14 and the fourth side plate 223 respectively away from the rotating end 21, with one end of the first connecting plate 31 connected to the end of the second side plate 14 away from the first side plate 13 and extending along the second direction, and one end of the second connecting plate 32 connected to the end of the fourth side plate 223 away from the third side plate 222 and also extending along the second direction, the first connecting plate 31 and the second connecting plate 32 are made to be parallel to each other in space, which helps to achieve a detachable connection between the two.

[0054] In one embodiment, the first connecting plate 31 is provided with a first connecting hole 33, and the second connecting plate 32 is provided with a second connecting hole 34, and the connector is connected to the first connecting hole 33 and the second connecting hole 34 in sequence.

[0055] By providing a first connecting hole 33 on the first connecting plate 31 and a second connecting hole 34 on the second connecting plate 32, and by connecting the fasteners sequentially to the first connecting hole 33 and the second connecting hole 34, a detachable connection between the first connecting plate 31 and the second connecting plate 32 is achieved. This not only ensures the stability of the connection but also greatly facilitates subsequent disassembly work.

[0056] In specific implementations, the connector can be a fastener such as a bolt.

[0057] In one embodiment, the connection structure further includes a handle 35, which includes a first bending plate 351 and a second bending plate 352; one end of the first bending plate 351 is connected to the second connecting plate 32, and the other end extends in a third direction away from the second connecting plate 32; one end of the second bending plate 352 is connected to the other end of the first bending plate 351, and the other end extends in a second direction away from the second connecting plate 32.

[0058] Since one end of the first bending plate 351 is firmly connected to the second connecting plate 32 and the other end extends outward along the third direction, it provides an initial point of force for gripping; one end of the second bending plate 352 is connected to the extended end of the first bending plate 351 and extends outward along the second direction, further expanding the gripping space, so that the operator can grip the handle 35 more comfortably and firmly to realize the rotation operation of the protective cover, thus improving the convenience of use.

[0059] In one embodiment, the connection structure further includes a limiting plate 36, one end of which is connected to the side of the first connecting plate 31 away from the second side plate 14, and the other end extends along a third direction away from the side of the first connecting plate 31.

[0060] Due to prolonged use or potential deviations in the manufacturing process, the first connecting hole 33 and the second connecting hole 34 of the protective cover may become misaligned. By setting the limiting plate 36, the position of the second connecting plate 32 can be constrained and calibrated to ensure that the first connecting hole 33 and the second connecting hole 34 always maintain a precise alignment, thereby ensuring the connection and fixation between the first connecting plate 31 and the second connecting plate 32.

[0061] In one embodiment, the limiting plate 36 and the first bending plate 351 are arranged sequentially along the first direction.

[0062] Since the limiting plate 36 and the first bending plate 351 are arranged sequentially along the first direction inside the device, this ingenious structural design not only achieves a highly compact spatial layout, effectively reducing the overall volume occupied by the device and improving space utilization, but also avoids interference problems between the handle 35 and the limiting plate 36 that may be caused by unreasonable spatial layout, thereby ensuring the normal functioning of the overall device.

[0063] In specific implementation methods, such as Figure 3 As shown, the fixing plate 12, the first side plate 13, the two second side plates 14, the first connecting plate 31, and the limiting plate 36 are integrally formed and are made of... Figure 3 It is formed by bending the bending lines shown.

Figure 6 It is formed by bending the bending lines shown.

[0065] In a specific implementation, the installation process of the switch protection device of this application is as follows: Before installation, confirm that the model and specifications of the switch protection device used are consistent with the model and specifications of the switch to avoid installation failure or safety hazards due to mismatch; install the base and protective cover on the fixed back plate respectively; close the protective cover to ensure that the protective cover can form a protective cavity with the base and be connected by the connecting structure; after installation, check whether the switch protection device is installed firmly and stably, ensuring that it can completely cover the switch that needs protection and can be used normally.

[0066] In a specific implementation, when the switch is needed, the protective cover is rotated to the second position separated from the base, at which point the switch can be operated; after the switch is used, the protective cover is rotated to the first position closed with the base, and the connector is sequentially connected to the first connecting hole 33 and the second connecting hole 34 to achieve the connection and locking between the protective cover and the base.
