Description

Technical Field

[0001] This utility model relates to the field of new energy power generation equipment technology, and in particular to an exposed cable protection device. Background Technology

[0002] In a photovoltaic power generation system, the inverter is a crucial device that converts the direct current (DC) generated by the solar panels into alternating current (AC). The bottom of the inverter enclosure typically has plugs for electrical connections to external cables. These plugs need to maintain a stable and reliable connection during normal use, while also ensuring ease of maintenance in the future.

[0003] Currently, the protection of inverter plugs mainly adopts the following methods:

[0004] One approach involves directly exposing the plug at the bottom of the inverter enclosure, relying solely on the plug's own protection rating to withstand external environmental influences. While this method is simple in structure, the plug's long-term exposure to the external environment makes it susceptible to rain, dust, and other contaminants, reducing connection reliability. Furthermore, the lack of effective cable management often leads to issues with cables being too long or too short during maintenance.

[0005] Another approach is to add a simple protective cover to the outside of the plug. While this method improves the plug's protection level to some extent, the cover usually only covers the plug itself and doesn't solve the cable management problem. Especially during maintenance, if it's necessary to replace the plug or adjust the cable length, rewiring is often required, which is cumbersome and can easily damage the cable. Utility Model Content

[0006] This utility model provides an exposed cable protection device that can effectively protect the plug of the inverter enclosure and store redundant cables for easy maintenance of the plug and cables in the future.

[0007] This utility model provides an exposed cable protection device, which is installed at the bottom of the inverter housing. The bottom of the inverter housing is provided with a plug for connecting cables. The exposed cable protection device includes: a housing with a cavity for accommodating the plug and cables, an open top for the housing, and a through hole for the cables to pass through at the bottom of the housing; and a winding component, which is installed inside the housing. Part of the cable is wound around the winding component and connected to the plug.

[0008] In one possible implementation, the bottom of the housing is provided with multiple sets of fixing holes around the wire threading hole, and the winding component is detachably connected to the fixing holes.

[0009] In one possible implementation, the winding component includes: a connecting plate; a post disposed at one end of the connecting plate, the post being inserted into and engaging with a fixing hole; and a winding post disposed at the other end of the connecting plate; wherein the cable is wound around the winding post.

[0010] In one possible implementation, there are two pins, which are arranged parallel to each other at one end of the connecting plate and are used to insert into the two fixing holes respectively.

[0011] In one possible implementation, multiple sets of fixing holes are evenly arranged along the circumference of the threading hole; each set of fixing holes includes at least three fixing holes arranged radially at intervals, and the distance between two adjacent fixing holes in a set of fixing holes is equal to the distance between two insertion posts.

[0012] In one possible implementation, multiple sets of fixing holes are provided along the width direction of the housing, and each set of fixing holes is spaced apart along the length direction of the housing; wherein, two winding members form a group, and each group of winding members is inserted into a set of fixing holes, and the cable is wound on the winding posts of the two winding members.

[0013] In one possible implementation, the bottom plate of the housing is provided with a sliding structure along its length, and multiple sliding structures are spaced apart along the width direction of the housing; wherein the winding member slides in engagement with the sliding structure.

[0014] In one possible implementation, the side of the housing is provided with an operating hole that communicates with the cavity, and a cover plate is provided inside the operating hole to control the opening and closing of the operating hole.

[0015] In one possible implementation, the operating holes include: a first operating hole disposed on the front side of the housing; and two second operating holes disposed on the left and right sides of the housing, respectively.

[0016] In one possible implementation, the top of the housing is provided with lugs for connecting to the inverter enclosure.

[0017] In one possible implementation, the top of the housing also includes elastic support members disposed on the top of the housing, the elastic support members being disposed on the four sides of the housing for elastically abutting against the inverter enclosure.

[0018] In one possible implementation, the insert and the fixing hole are interference-fitted.

[0019] In one possible implementation, the winding component is integrally formed.

[0020] The technical solution provided by this utility model embodiment has the following advantages compared with the prior art:

[0021] This utility model provides an exposed cable protection device that, by placing the housing at the bottom of the inverter enclosure, uses a housing with a receiving cavity to provide overall protection for the plug. Compared to existing technologies where the plug is directly exposed or only covered by a simple protective cover, the housing of this utility model can form a complete protective space, thereby isolating the plug from the influence of the external environment in all directions. The top of the housing connects to the bottom of the inverter enclosure through an open opening, forming a sealed connection; the receiving cavity of the housing completely covers the plug, preventing the intrusion of rainwater, dust, and other harmful substances; the cable pass-through hole at the bottom of the housing ensures that the cable can be led out in an orderly manner without affecting the overall protective effect. The cable management problem is solved by incorporating a winding component arranged around the cable pass-through hole inside the housing. In existing technologies, cables are often directly connected to the plug, lacking standardized storage and management measures, which can easily lead to loose cables or excessive tension. This utility model, by incorporating a winding component inside the housing, provides a dedicated space for cable winding. After the cable is introduced through the cable hole, it can be wound in a standardized manner on the winding device. This not only stores an appropriate amount of redundant cable for easy maintenance of the plug and cable later, but also ensures that the connection between the cable and the plug is not affected by external forces.

[0038] 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, not all, of the embodiments of this utility model. 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.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0041] like Figures 1-8 As shown, this utility model embodiment provides an exposed cable protection device, which is disposed at the bottom of inverter housing a. The bottom of inverter housing a is provided with a plug c for connecting cable b. The exposed cable protection device includes: a housing 1, which has a cavity 11 for accommodating plug c and cable b. The top of housing 1 is an open opening, and the bottom of housing 1 is provided with a through hole 12 for cable b to pass through. A winding member 2 is disposed inside housing 1 and is disposed around the through hole 12. A portion of cable b is wound around the winding member 2 and connected to plug c.

[0042] In this invention, the housing 1 is positioned at the bottom of the inverter enclosure a, and the housing 1 with a receiving cavity 11 provides overall protection for the plug c. Compared to the prior art where the plug c is directly exposed or only covered by a simple protective cover, the housing 1 of this invention forms a complete protective space, thereby isolating the plug c from the external environment in all directions. The top of the housing 1 connects to the bottom of the inverter enclosure a through an open opening, forming a sealed connection; the receiving cavity 11 of the housing 1 completely covers the plug c, preventing the intrusion of rainwater, dust, and other harmful substances; the cable hole 12 at the bottom of the housing 1 ensures that the cable b can be led out in an orderly manner without affecting the overall protective effect. The cable management problem is solved by the winding component 2 arranged around the cable hole 12 inside the housing 1. In the prior art, the cable b is often directly connected to the plug c, lacking standardized storage and management measures, which easily leads to the cable b becoming loose or under excessive tension. This invention, by setting the winding component 2 inside the housing 1, provides a dedicated space for winding the cable b. After cable b is introduced through the threading hole 12, it can be wound in a standardized manner on the winding piece 2. This not only stores an appropriate amount of redundant cable b, which is convenient for the later maintenance of plug c and cable b, but also ensures that the connection between cable b and plug c is not affected by external forces.

[0043] Specifically, the top of the housing 1 features an open design for easy docking and installation with the inverter enclosure a; the bottom has a cable pass-through hole 12 for the orderly exit of cable b; and a winding component 2 is arranged around the cable pass-through hole 12 to provide winding space for cable b. This structural design ensures good operability during installation and use.

[0044] In one specific embodiment, when the photovoltaic inverter needs to be installed or maintained, the connection status of the plug c can be directly observed through the opening of the housing 1. The cable b led out through the wire hole 12 is connected to the plug c after being wound by the winding member 2. The whole process is convenient to operate and ensures the reliability of the connection.

[0045] In related technologies, the plug c is usually directly exposed at the bottom of the inverter enclosure a, or simply covered with a protective cover. This method not only makes the plug c susceptible to the influence of the external environment, but also makes it difficult to handle excess cables b during maintenance.

[0046] In this embodiment of the utility model, by setting a housing 1 with a cavity 11, not only can a closed protective space be provided for the plug c to prevent the influence of external factors such as dust and rain, but the setting of the winding component 2 also solves the cable b management problem and provides convenient conditions for later maintenance.

[0047] In some embodiments, the bottom of the housing 1 is provided with a plurality of fixing holes 13 around the wire hole 12, and the winding member 2 is detachably connected to the fixing holes 13.

[0048] In this invention, multiple sets of fixing holes 13 are provided around the threading hole 12 at the bottom of the housing 1, and the winding component 2 is detachably connected to the fixing holes 13, thereby enabling flexible adjustment of the position of the winding component 2. Its working principle is to utilize the multiple sets of fixing holes 13 to provide different installation position options, and to achieve quick installation and adjustment of the winding component 2 through a detachable connection.

[0049] like Figure 3 As shown, specifically, multiple sets of fixing holes 13 are distributed circumferentially along the threading hole 12. Each set of fixing holes 13 can be used to install the winding component 2, allowing the installation position of the winding component 2 to be adjusted according to actual needs. The detachable connection method facilitates the disassembly and assembly of the winding component 2, improving maintenance efficiency.

[0050] In one specific embodiment, when it is necessary to adjust the position of the winding component 2 according to different plug specifications c or different wiring requirements, it is only necessary to remove the winding component 2 from the original fixing hole 13 and then install it into the fixing hole 13 in the appropriate position. The operation is simple and quick.

[0051] Moreover, in this embodiment of the utility model, by setting multiple sets of fixing holes 13 and adopting a detachable connection method, the installation position of the winding component 2 can be selected in multiple ways, which can better adapt to different specifications of plugs c and different wiring requirements, thereby improving the applicability of the device.

[0052] In some embodiments, the winding member 2 includes: a connecting plate 21; a plug 22 disposed at one end of the connecting plate 21, the plug 22 being inserted into and engaged with the fixing hole 13; and a winding post 23 disposed at the other end of the connecting plate 21; wherein the cable b is wound around the winding post 23.

[0053] In this invention, by designing the winding component 2 as a combined structure comprising a connecting plate 21, a plug 22, and a winding post 23, stable installation and cable b storage functions are achieved. Its working principle is based on the insertion and engagement of the plug 22 with the fixing hole 13 to achieve installation positioning, the winding post 23 to provide space for cable b winding, and the connecting plate 21 to organically connect the two functional components.

[0054] Specifically, the connecting plate 21 serves as a basic support component, with a post 22 at one end for insertion and engagement with the fixing hole 13, and a winding post 23 at the other end for winding the cable b. This structural design allows different functional components to handle the installation and use processes, improving the reliability of the structure.

[0055] In one specific embodiment, when installing the winding component 2, simply inserting the post 22 into the fixing hole 13 completes the positioning and fixing. Then, the cable b can be wound around the winding post 23 for storage and management. The entire process is simple to operate and ensures the stability of the winding component 2.

[0056] In this embodiment of the utility model, the clearly defined three-component structure design not only makes the installation process more standardized, but also provides a dedicated space for cable winding, which greatly improves the convenience and reliability of use.

[0057] In some embodiments, the insertion post 22 is interference-fitted with the fixing hole 13.

[0058] In this invention, a more robust connection between the winding component 2 and the housing 1 is achieved by using an interference fit between the insertion post 22 and the fixing hole 13. Its working principle utilizes the elastic deformation characteristics of the material to create a stable frictional force at the mating point, thereby enhancing the reliability of the connection.

[0059] Specifically, the interference fit means that the outer diameter of the insert 22 is slightly larger than the inner diameter of the fixing hole 13. A certain force needs to be applied during installation. After installation, the elastic deformation of the material will generate continuous radial pressure to ensure the stability of the connection.

[0060] In one specific embodiment, when the cable b is wound on the winding post 23 or subjected to external force, the frictional force generated by the interference fit can effectively prevent the post 22 from loosening or falling off, ensuring that the winding member 2 always remains in the predetermined position.

[0061] In some embodiments, the winding component 2 is integrally formed.

[0062] In this invention, by designing the winding component 2 as a one-piece molded structure, higher structural strength and reliability are achieved. Its working principle is to eliminate connection points through integral molding, avoiding stress concentration and improving load-bearing capacity.

[0063] Specifically, the one-piece winding component 2 includes a connecting plate 21, a plug 22, and a winding post 23. All components are formed in one step during manufacturing, eliminating the need for assembly. This design not only improves overall strength but also simplifies the production process.

[0064] In one specific embodiment, when the winding member 2 is subjected to the stress generated by the winding of the cable b, the integrally formed structure can distribute the stress more evenly and avoid local damage; at the same time, the absence of connecting parts also reduces the risk of parts loosening or falling off.

[0065] In some embodiments, there are two insertion posts 22, which are arranged in parallel at one end of the connecting plate 21 and are used to insert into two fixing holes 13 respectively.

[0066] In this invention, two parallel inserts 22 are provided and inserted into the fixing holes 13 respectively, thus achieving dual-point fixation of the winding component 2. Its working principle utilizes the supporting torque formed by the two fixing points to effectively prevent the winding component 2 from rotating or tilting during use.

[0067] Specifically, two inserts 22 are arranged parallel to each other at one end of the connecting plate 21, and both fixing holes 13 must be inserted simultaneously during installation. This dual-point fixing design not only increases the support area but also provides a restraining force to prevent rotation.

[0068] In one specific embodiment, when cable b is wound on the winding post 23, an eccentric torque may be generated, causing the winding member 2 to rotate. However, by fixing it with two parallel posts 22, this rotational tendency can be effectively resisted, maintaining the stability of the winding member 2.

[0069] In this embodiment of the invention, the double-pin 22 design not only provides a more reliable fixing effect, but also simplifies the installation and positioning process, achieving stable support without the need for additional anti-rotation structures.

[0070] In some embodiments, multiple sets of fixing holes 13 are uniformly arranged along the circumference of the wire hole 12; each set of fixing holes 13 includes at least three fixing holes 13 arranged radially at intervals, and the distance between two adjacent fixing holes 13 in a set of fixing holes 13 is equal to the distance between the two insertion posts 22.

[0071] In this invention, the circumferentially uniform distribution and radially spaced fixing holes 13, along with matching the spacing between adjacent fixing holes 13 to the spacing between the inserts 22, achieve precise adjustment of the winding component 2's installation position. Its working principle is to provide standardized installation options using a regular hole distribution, and to ensure installation accuracy through spacing matching.

[0072] Specifically, the fixing holes 13 are evenly distributed around the circumference of the wire-passing holes 12, and each group contains at least three fixing holes 13 arranged radially at intervals. The distance between adjacent fixing holes 13 is equal to the distance between the two insertion posts 22. This design ensures both the diversity of installation positions and the accuracy of installation.

[0073] In one specific embodiment, when it is necessary to adjust the position of the winding component 2 according to the actual application, different combinations of fixing holes 13 can be selected. Due to the standardized design of the spacing, the position adjustment can be completed quickly and accurately.

[0074] In this embodiment of the utility model, the reasonable layout design of the fixing holes 13 not only provides ample space for position selection, but also ensures the standardization and convenience of the installation process.

[0075] In some embodiments, a fixing part is provided at the end of the winding post away from the connecting plate. The fixing part is used to fix the cable and prevent the cable from scattering. Specifically, the fixing part can be a circular ring to prevent the cable wound on the winding post from scattering; it can also be an elastic clip to clamp the cable at the end of the winding post to prevent the cable from scattering; or it can be a cable groove to insert the cable into the cable groove to fix the cable.

[0076] like Figure 6 , 7 As shown, in some embodiments, multiple sets of fixing holes 13 are provided along the width direction of the housing 1, and each set of fixing holes is spaced apart along the length direction of the housing 1.

[0077] Among them, two winding components 2 form a group, and each group of winding components 2 is connected to a group of fixing holes 13. The cable b is wound on the winding post 23 of the two winding components 2.

[0078] In this invention, by setting multiple sets of fixing holes 13, with two winding members 2 arranged as a set, the cable b is wound around two winding members 2, which can effectively reduce the entanglement of the cable b on a single winding member 2, and at the same time, it can store longer cables b. Each set of fixing holes 13 includes multiple fixing holes 13 arranged at intervals, which can make the front and rear winding members 2 staggered when the winding members 2 are arranged, which is convenient for later maintenance; and it is also convenient to adjust the fixing position of the winding members 2 according to the length of the cable b. For example, after the remaining length of the cable b becomes shorter, the distance between the two winding members 2 can be shortened. When the remaining length of the cable b continues to shorten, a single winding member 2 can be used to wind the cable b.

[0079] like Figure 8 As shown, in a specific embodiment, the winding post 23 is a U-shaped structure with its opening facing the threading hole 12.

[0080] In this invention, by setting the winding post into a U-shaped structure, the horizontal space inside the housing can be fully utilized, thereby reducing the height of the housing, while also satisfying the storage requirements for cable b.

[0081] like Figure 5 As shown, in some embodiments, the bottom plate of the housing 1 is provided with a sliding structure 19 along the length direction, and multiple sliding structures 19 are spaced apart along the width direction of the housing 1; wherein, the winding member 2 is slidably engaged with the sliding structure 19.

[0082] In this invention, the winding member 2 is slidably engaged with the sliding structure 19, allowing adjustment of the position of the winding member 2 along its length. When winding the cable, the cable can be wound onto two winding members 2 on the same sliding structure 19, or onto a single winding member 2. As the cable is used, the redundant portion decreases, allowing adjustment of the cable via the sliding winding member 2 while maintaining tension and ensuring the neatness of the cable inside the housing.

[0083] like Figure 9 As shown, specifically, the winding member 2 is provided with a sliding part 24 and a winding part 25. The sliding part 24 is slidably engaged with the sliding structure 19, which is a strip-shaped hole. The sliding part 24 slides along the strip-shaped hole. The sliding part 24 includes a connecting rod 241, a limiting piece 242, an elastic element 243, and a clamping piece 244. The connecting rod 241 passes through the strip-shaped hole. The limiting piece 242 is disposed at one end of the connecting rod 241. The clamping piece 244 is sleeved on the outer periphery of the connecting rod 241 and can slide along the axial direction of the connecting rod 241 and rotate circumferentially. The elastic element 243 is disposed between the clamping piece 244 and the limiting piece 242. When it is necessary to slide the winding member 2, the elastic member 243 is compressed by lifting the winding member 2, which separates the winding part 25 from the bottom plate of the housing 1, so that the winding member 2 can be slid. After the position adjustment of the winding member 2 is completed, the winding member 2 is released. Under the action of the elastic member 243, the winding part 25 abuts against the bottom plate of the housing 1 again. The clamping piece 244 and the winding part 25 clamp the bottom plate of the housing 1, thereby ensuring the stability of the winding member 2.

[0084] In some embodiments, the side of the housing 1 is provided with an operation hole communicating with the cavity 11, and a cover plate 16 for controlling the opening and closing of the operation hole is provided inside the operation hole.

[0085] In this invention, by providing an operating hole communicating with the cavity 11 on the side of the housing 1 and equipping it with a controllable cover plate 16, a balance between ease of maintenance and sealing is achieved. Its working principle is to utilize the operating hole to provide a maintenance channel, and to switch between daily sealing and maintenance needs by controlling the opening and closing of the cover plate 16.

[0086] Specifically, the operating hole is directly connected to the internal cavity 11, providing a working passage for maintenance personnel; the cover plate 16 ensures good sealing in non-maintenance state, preventing the external environment from affecting the internal plug c.

[0087] In one specific embodiment, when it is necessary to inspect or maintain plug c, it can be operated from the side simply by opening the corresponding cover 16 without disassembling the entire device; while in daily use, closing the cover 16 can form a complete protective space.

[0088] In this embodiment of the utility model, the design of the operating hole and the cover plate 16 not only ensures the protective effect during daily use, but also provides a convenient maintenance channel, significantly improving practicality.

[0089] In some embodiments, the operating holes include: a first operating hole 14 disposed on the front side of the housing 1; and two second operating holes 15 disposed on the left and right sides of the housing 1, respectively.

[0090] In this invention, a multi-angle operating channel system is formed by providing a first operating hole 14 on the front side of the housing 1 and second operating holes 15 on the left and right sides. Its working principle is to provide omnidirectional maintenance space using operating holes in different positions, meeting the needs of different maintenance scenarios.

[0091] Specifically, the first operating hole 14 on the front is mainly used for frontal operation, while the second operating holes 15 on the left and right sides provide space for side operation. This layout design allows maintenance personnel to choose the most suitable operating angle according to the actual situation.

[0092] In one specific embodiment, when multiple wiring tasks need to be handled simultaneously, maintenance personnel can operate through different access ports at the same time, greatly improving work efficiency; in space-constrained installation environments, the most easily accessible access port can also be selected for maintenance.

[0093] In this embodiment of the invention, the reasonable layout of multiple operating holes not only provides a larger operating space but also increases the flexibility of maintenance, enabling it to adapt to various installation environments and maintenance scenarios.

[0094] Optionally, an access hole can be provided on the back of the housing for maintenance of rear cables and plugs.

[0095] In some embodiments, the top of the housing 1 is provided with a lug 17 for connecting to the inverter housing a.

[0096] In this invention, a reliable connection between the exposed cable protection device and the inverter housing a is achieved by setting a hook 17 on the top of the housing 1 as a connector. Its working principle is to utilize the hook 17 structure to provide vertical support while preventing horizontal displacement of the device.

[0097] Specifically, the mounting lug 17 is located on the top of the housing 1 and is hooked to the inverter enclosure a. This connection method can both support the weight of the device and prevent the device from shaking or falling off during use.

[0098] Optionally, a bracket can be installed at the bottom rear of the housing to support the housing and fix it to the bottom of the inverter.

[0099] In one specific embodiment, when installing the exposed cable protection device, simply align the hanging ear 17 with the mating structure on the inverter housing a to quickly complete the positioning and installation; in daily use, the design of the hanging ear 17 also ensures the stability of the device position, and it will not easily fall off even under external force.

[0100] In this embodiment of the invention, the design of the hanging ear 17 not only simplifies the installation process but also provides a reliable support effect, greatly improving the safety of the device.

[0101] In some embodiments, the top of the housing 1 further includes an elastic support member 18 disposed on the top of the housing 1. The elastic support member 18 is disposed on the four sides of the housing 1 and is used to elastically abut against the inverter housing a.

[0102] In this invention, elastic support members 18 are provided on the four sides of the top of the housing 1, achieving elastic support between it and the inverter housing a. Its working principle is to utilize the deformation characteristics of the elastic support members 18 to provide a buffering effect while ensuring uniform force distribution on the contact surface.

[0103] Specifically, the elastic support members 18 are disposed on the four sides of the housing 1, and can generate appropriate elastic deformation when in contact with the inverter enclosure a. This design not only provides stable support force, but also absorbs external vibrations and protects the reliability of the plug c connection.

[0104] In one specific embodiment, when the inverter vibrates during operation, the elastic support 18 can effectively absorb these vibrations and prevent the vibrations from being transmitted to the plug c connection point; at the same time, the support structure evenly arranged on all four sides also ensures stable contact between the device and the inverter housing a.

[0105] In this embodiment of the utility model, the elastic support member 18 not only ensures the support effect but also provides a vibration reduction function, effectively extending the service life of the plug c.

[0106] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting.
