[0002] Existing string inverters, energy storage converters, and other power conversion equipment are typically installed outdoors. These devices usually have ventilation openings to allow air to flow in and carry away the heat generated during operation. In practice, during spring and autumn, impurities such as willow catkins and fallen leaves can easily enter the power conversion equipment through these openings. The heat buildup inside the equipment during operation can also attract insects and flies into the ventilation openings, causing blockages in the external heat dissipation channels and affecting equipment cooling and operation. Furthermore, each blockage requires frequent manual cleaning, especially during the peak willow catkin season in April and May, and the withering vegetation season in autumn and winter, leading to frequent manual cleaning.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] This utility model provides a protective unit and a converter device including a converter 40 and the protective unit of this utility model. The converter device can be installed outdoors. In the spring, summer and autumn seasons when there are many wastes such as willow catkins and fallen leaves, the protective unit of this utility model can block willow catkins, fallen leaves, insects and flies to protect the converter 40. This utility model does not limit the specific type of converter 40. The converter 40 can be an inverter, rectifier, DC converter 40, AC converter 40, etc.

[0032] See Figures 1-2 , Figures 5-8 The protective unit of this utility model includes a mesh cover mounting component 20 and a protective mesh cover 30. The mesh cover mounting component 20 is used to connect the converter 40 and has a ventilation opening 25. The mesh cover mounting component 20 includes at least a mesh cover guide rail 21 passing through the edge of the ventilation opening 25. The protective mesh cover 30 is detachably slidably connected to the mesh cover guide rail 21. The protective mesh cover 30 can slide along the mesh cover guide rail 21 to a protective position. In the protective position, the protective mesh cover 30 covers the ventilation opening 25. At this time, at least a part of the converter 40 is covered by the protective mesh cover 30. The protective mesh cover 30 includes a breathable mesh body 31. The mesh body 31 allows air to pass through and enter the ventilation opening 25. The part of the converter 40 covered by the protective mesh cover 30 is blown away by the air, thereby removing the heat generated by the converter 40 during operation. The mesh body 31 can also block insects, flies, willow catkins, fallen leaves and other waste outside the ventilation opening 25 to protect the converter 40.

[0033] The mesh cover holder 20 supports the protective mesh cover 30 and allows the protective mesh cover 30 to slide to open and close the ventilation opening 25. When it is necessary to clean foreign objects adhering to the protective mesh cover, the protective mesh cover 30 is slid along the mesh cover guide rail 21 until the protective mesh cover 30 slides off the mesh cover guide rail 21 and separates from the mesh cover holder 20. After cleaning, the protective mesh cover 30 is reinstalled onto the mesh cover guide rail 21 and slid to the protective position. Therefore, this utility model simplifies the disassembly and assembly process of the protective unit, reduces the workload of disassembling and assembling the protective mesh cover 30 to open and close the ventilation opening 25, and allows for easy and quick cleaning of the protective mesh cover 30.

[0034] See Figures 3-4 In some embodiments, the converter 40 includes a housing 10 and a heat sink 70. A mesh cover mounting member 20 is detachably connected to the housing 10. The mesh cover mounting member 20 and the housing 10 together form a mounting cavity, which is connected to a ventilation opening 25 and accommodates the heat sink 70. The heat sink 70 is surrounded by the mesh cover mounting member 20 and the housing 10 to prevent collision with external objects. The protective mesh cover 30 at least covers the heat sink 70. The heat sink 70 may specifically be a heat sink fin. In addition, the heat sink 70 may also include devices such as a cooling fan. The cooling fan can actively draw air to allow air to enter the mounting cavity through the protective mesh cover 30. The mesh 31 blocks waste of a certain size from outside the mounting cavity. When it is necessary to clean the protective unit, the protective mesh cover 30 can be directly slid off the mesh cover guide rail 21 and removed for cleaning.

[0035] See Figures 2-4 , Figures 6-8The housing 10 includes a top plate 11 and side walls 12. The mesh cover mounting component 20 includes a bottom plate 22 and a disassembly part 29, which is detachably connected to the housing 10. The bottom plate 22 is rectangular and has a drainage hole 27 that communicates with the mounting cavity. The drainage hole 27 can drain the liquid accumulated in the mounting cavity to protect the converter 40 from moisture damage. The mesh cover mounting component 20 also includes a first side plate 23 and a second side plate 24 connected to the two short sides of the bottom plate 22 respectively. The two short sides of the bottom plate 22 are two parallel short sides of the rectangular bottom plate 22. The first side plate 23 and the second side plate 24 both protrude relative to the same side of the bottom plate 22. The bottom plate 22, the first side plate 23 and the second side plate 24 together define a ventilation opening 25.

[0036] Optionally, the mesh cover guide rail 21 is disposed at the edge of the mesh cover mounting member 20, and the protective mesh cover 30 further includes a frame 32 disposed at the edge of the mesh body 31, the frame 32 and the mesh cover guide rail 21 being slidably engaged. In some embodiments, the mesh cover guide rail 21 may be disposed on at least one of the first side plate 23 and the second side plate 24, so that the protective mesh cover 30 slides in the vertical direction. Preferably, in this embodiment, the mesh cover guide rail 21 is disposed on one edge of the long side of the base plate 22, so that the protective mesh cover 30 slides along the length direction of the base plate 22, and the mesh cover guide rail 21 can provide support for the protective mesh cover 30.

[0037] Optionally, the disassembly and assembly units are installed in pairs, see [reference]. Figure 5 , Figures 7-10 At least two detachable parts 29 are respectively provided at both ends of the base plate 22. The detachable parts 29 can be connected to the base plate 22 by threaded fasteners or riveting, or they can be fixed by welding. The detachable parts 29 can also be provided on the first side plate 23 and / or the second side plate 24. The detachable parts 29 can be connected to the first side plate 23 and the second side plate by threaded fasteners or riveting, or they can be fixed by welding. The mesh cover mounting member 20 is detachably connected to the housing 10 through the detachable parts 29. The detachable parts 29 can be connected to the housing 10 by threaded fasteners or riveting. It is worth noting that the mesh cover mounting member 20 and the housing 10 can also form a non-detachable connection. For example, the detachable parts 29 can be fixed to the housing 10 by welding.

[0038] Optionally, see Figure 1 and Figure 3The base plate 22 is located on the side of the heat dissipation section 70 that is relatively close to the ground and is horizontally set. The first side plate 23 and the second side plate 24 protrude from the side of the base plate 22 that is not facing the ground. Both the first side plate 23 and the second side plate 24 are vertically set. The mesh cover guide rail 21 extends in a straight line in the horizontal direction. The protective mesh cover 30 slides in a straight line on the mesh cover guide rail 21 in the horizontal direction. When the protective mesh cover 30 is in the protective position, the protective mesh cover 30 is vertically set. The liquid in the housing cavity can be collected to the base plate 22 under the action of gravity and then discharged through the drain hole 27. The converter equipment also includes a mounting beam 50 and a clamp 60. The mounting beam 50 is fixedly connected to the housing 10. The clamp 60 is clamped to the column and connected to the mounting beam 50. A sliding gap is formed between the mounting beam 50 and the housing 10. The protective mesh cover 30 can slide into and out of the sliding gap along the mesh cover guide rail 21. When the protective mesh cover 30 slides, the housing 10 and the mounting beam 50 will not interfere with the protective mesh cover 30.

[0039] Preferably, the base plate 22, the first side plate 23, and the second side plate 24 are integrally formed structures. The first side plate 23 and the second side plate 24 are bent and connected to the two short sides of the base plate 22 respectively. The base plate 22 and the mesh cover guide rail 21 can also be integrally formed structures.

[0040] Further, see Figure 9 In some embodiments, the mesh cover mounting member 20 includes a limiting part 26 that stops the protective mesh cover 30 when it is in the protective position. When personnel reinstall the protective mesh cover 30 onto the mesh cover guide rail 21 and apply force to the protective mesh cover 30 in an attempt to make it cover the ventilation opening 25 again, the limiting part 26 can prevent the protective mesh cover 30 from sliding too much and missing the protective position. Personnel can determine whether the protective mesh cover 30 is correctly covering the ventilation opening 25 by whether the limiting part 26 stops the protective mesh cover 30. See also Figure 8 and Figure 9 Optionally, the mesh cover guide rail 21 includes a starting end and an ending end, which extend to the short sides of the base plate 22 on both sides, respectively. A limiting part 26 is provided on the first side plate 23, and the frame 32 includes a sliding side 321 that is detachably and slidably engaged with the mesh cover guide rail 21. One end of the sliding side 321 is first connected to the starting end, and then a force is applied to the protective mesh cover 30 to make the protective mesh cover 30 gradually approach the first side plate 23 and the ending end. During this process, the engagement length between the sliding side 321 and the mesh cover guide rail 21 gradually increases. When the end of the sliding side 321 initially connected to the starting end reaches the ending end, the limiting part 26 abuts against the frame 32 to stop the protective mesh cover 30 from continuing to slide. In other embodiments, the limiting part 26 may also be provided on the second side plate 24.

[0041] See Figure 10In some embodiments, the mesh cover mounting member 20 further includes a positioning part 28 and the protective mesh cover 30 is fixedly provided with an adapter part 33. When the protective mesh cover 30 is in the protective position, the positioning part 28 and the adapter part 33 are inserted and engaged so that the protective mesh cover 30 and the mesh cover mounting member 20 are locked and fixed by the positioning part 28 and the adapter part 33. This locking effect can restrict the degree of freedom of the protective mesh cover 30 and prevent the ventilation opening 25 from being accidentally opened due to the protective mesh cover 30 accidentally falling off the mesh cover mounting member 20, so as to ensure that the protective mesh cover 30 is stably covered on the ventilation opening 25 when the converter equipment is in use. Optionally, the positioning part 28 includes a positioning pin extending along the length of the mesh cover guide rail 21, and the adapter part 33 has a positioning hole for the positioning pin to be inserted and engaged. The positioning pin is fixed relative to the mesh cover guide rail 21. When a person moves the protective mesh cover 30 to the protective position, the positioning pin is inserted into the positioning hole. When a person moves the protective mesh cover 30 away from the protective position and attempts to remove the protective mesh cover 30 from the mesh cover mounting part 20, the positioning pin is removed from the positioning hole.

[0042] See Figure 10 The positioning pin protrudes from the side of the first side plate 23 that is relatively close to the second side plate 24. The adapter part 33 is fixedly connected to the side of the frame 32 that is relatively close to the first side plate 23. When the protective net cover 30 is in the protective position, the side of the first side plate 23 that is relatively close to the second side plate 24 fits against the adapter part 33 to stop the protective net cover 30 from continuing to slide. At this time, the positioning pin is inserted into the positioning hole. When the personnel move the protective net cover 30 to slide away from the first side plate 23, the cooperation length between the sliding side 321 and the net cover guide rail 21 gradually decreases. The adapter part 33 leaves the first side plate 23 and gradually moves away from the first side plate 23. The positioning pin is withdrawn from the positioning hole. The positioning pin extends along the length direction of the net cover guide rail 21, which can make the positioning pin more smoothly inserted and withdrawn from the positioning hole, and can protect the positioning pin and the adapter part 33 from premature wear and failure. In other embodiments, the positioning pin may also protrude from the side of the second side plate 24 opposite to the first side plate 23, and the adapter 33 is fixedly connected to the side of the frame 32 that is relatively close to the second side plate 24. When the protective net cover 30 is in the protective position, the adapter 33 abuts against the side of the second side plate 24 opposite to the first side plate 23, and at this time the positioning pin is inserted into the positioning hole.

[0043] In some embodiments, when the protective mesh cover 30 is in the protected position, the protective mesh cover 30 is fixedly connected to the housing 10 by a first fastener, see reference. Figures 2-4 , Figure 6 and Figure 8The inverter 40 has a first fastening hole 13 on its housing 10 and a second fastening hole 322 on its frame 32. When the protective net cover 30 slides to the protective position, the first fastener passes through the first fastening hole 13 and the second fastening hole 322 and fixes the frame 32 and the housing 10. The first fastener can ensure that the protective net cover 30 will not be lost. Before disassembling the protective net cover 30 and the net cover mounting part 20, the first fastener must be removed to contact the locking between the housing 10 and the frame 32.

[0044] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
