[0002] With the rapid development of photovoltaic, energy storage, wind power and other industries, the demand for outdoor cabinets or outdoor containers is increasing. However, the protection level of traditional cabinets is low. When the equipment is in operation, the air inlets and outlets need to be fully opened to ensure sufficient heat dissipation capacity. At this time, if there is windy, sandy, rainy or snowy weather, rain and snow can easily enter the box from the air outlet and cause damage to the equipment. Utility Model Content

[0003] The main purpose of the utility model is to provide a protection structure and a grid-connected test device, aiming to improve the protection level of the cabinet during normal operation.

[0004] To achieve the above-mentioned purpose, the protective structure proposed in the utility model includes a shell, a fan and an air outlet duct; the shell has an air outlet; the fan is arranged in the shell; the fan has an air inlet side and an air outlet side that are connected to each other; the air outlet duct is arranged in the shell, and the two ends of the air outlet duct are respectively connected to the air outlet side of the fan and the air outlet; in the direction from the air outlet to the air outlet side of the fan, at least part of the air outlet duct extends upward.

[0005] In one embodiment, the housing has a side wall, and the air outlet is disposed on the side wall.

[0006] In one embodiment, the air outlet duct comprises:

[0007] A first connecting section, the first connecting section is arranged parallel to the air outlet direction of the air outlet and is connected to the air outlet; and

[0008] A second communicating section, one end of which is communicated with the first communicating section, and the other end of which extends upward.

[0009] In one embodiment, the shell further has an air inlet, a first louver is installed at the air inlet, and a second louver is installed at the air outlet.

[0010] In one embodiment, the protective structure further includes a cover plate assembly, which is movably connected to the shell, and the cover plate assembly is installed at the air inlet and / or the air outlet.

[0011] In one embodiment, the cover plate assembly is hinged to the housing.

[0012] In one embodiment, a side of the cover plate assembly connected to the shell is close to the top of the air outlet.

[0013] In one embodiment, the cover plate assembly comprises:

[0014] a cover body, the cover body being hinged to the shell; and

[0015] A support member, one end of which is movably connected to the shell, and the other end of which is movably connected to the cover body, so as to support the cover body when the cover body is in an open state.

[0016] In one embodiment, the cover assembly further includes a protective cloth, and the protective cloth is connected to an edge of the cover body.

[0017] The utility model also provides a cabinet, comprising a main component and the above-mentioned protective structure, wherein the main component is arranged in the shell.

[0018] The technical solution of the utility model is that an air outlet is provided on the shell, and the fan is provided in the shell. The fan has an air inlet side and an air outlet side that are interconnected. The two ends of the air outlet duct are respectively connected to the air outlet side of the fan and the air outlet of the shell. Then, under the action of the fan, the fan can blow the hot air inside the shell to the air outlet through the air outlet duct, and discharge it from the air outlet of the shell, thereby achieving the effect of heat dissipation of the main components in the shell. By setting the air outlet duct, on the one hand, it can have a good guiding effect on the hot air in the shell, so that the hot air flows to the air outlet through the air outlet duct to effectively dissipate the heat of the main components in the shell. On the other hand, it can make the rain and snow blown in from the air outlet only move in the opposite direction along the air outlet duct, avoiding rain and snow from entering the area outside the air outlet duct in the shell through the air outlet. By extending at least part of the air outlet duct upward in the direction from the air outlet to the air outlet side of the fan, on the one hand, the resistance of rain and snow to the upward movement after entering the air duct becomes greater, and on the other hand, the direction of power provided by the fan is opposite to the direction of travel of rain and snow. Therefore, the operation of the fan further increases the resistance of rain and snow entering the shell, and may even cause rain and snow to be discharged from the shell, thereby achieving a higher level of protection for the protective structure.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0035] With the rapid development of industries such as photovoltaics, energy storage, and wind power generation, the demand for outdoor cabinets and outdoor containers is increasing. However, the protection level of traditional cabinets is low. When the equipment is in operation, the air inlet and outlet 120 need to be fully opened to ensure sufficient heat dissipation capacity. The distance from the air inlet 110 to the power supply is long, so a high-protection-level shutter can be set at the air inlet 110 to achieve a higher protection level. However, since the distance from the air outlet 120 to the main device 600 in the cabinet is short, a high-protection-level shutter cannot be installed at the air outlet 120. If the equipment encounters windy, sandy, rainy, and snowy weather during operation, rain and snow can easily enter the box from the air outlet 120, causing damage to the equipment.

[0036] In order to improve the protection level of the cabinet during normal operation, the utility model proposes a protection structure.

[0037] Please refer to Figures 1 to 3 In one embodiment of the utility model, the protective structure includes a shell 100, a fan 200 and an air outlet duct 300; the shell 100 has an air outlet 120; the fan 200 is arranged in the shell 100; the fan 200 has an air inlet side and an air outlet side that are connected to each other; the air outlet duct 300 is arranged in the shell 100, and the two ends of the air outlet duct 300 are respectively connected to the air outlet side of the fan 200 and the air outlet 120; in the direction from the air outlet 120 to the air outlet side of the fan 200, at least a part of the air outlet duct 300 extends upward.

[0038] The air outlet 120 of the housing 100 is used to blow out the hot air in the housing 100, so as to achieve the effect of heat dissipation of various components inside the housing 100. By arranging the fan 200 in the housing 100, on the one hand, the heat dissipation efficiency of the heat inside the housing 100 can be improved. The two ends of the air outlet duct 300 are respectively connected to the air outlet side of the fan 200 and the air outlet 120, so that the wind blown out from the air outlet side of the fan 200 can enter the air outlet duct 300, and then blow to the air outlet 120 through the air outlet duct 300, thereby providing a guiding effect for the air outlet direction. Specifically, the air outlet 120 of the housing 100 can be opened on the side wall or top of the housing 100.

[0039] In the direction from the air outlet 120 to the air outlet side of the fan 200, by extending at least part of the air outlet duct 300 upward, when the rain and snow break through the air outlet 120 and enter the air duct, the rain and snow will have a tendency to move upward in at least part of the interval in the air duct, and at this time, the rain and snow will have a greater resistance when moving, thereby weakening the running speed of the rain and snow, and reducing the risk of the rain and snow continuing to erode the power inside the shell 100. In addition, when the equipment is running, the fan 200 is also in operation, and the wind force provided by the fan 200 is opposite to the direction of the rain and snow, and the wind force and wind speed provided by the fan 200 are relatively large, so under the action of the wind force of the fan 200, it is further convenient to discharge the rain and snow out of the shell 100, so as to achieve a higher protection effect. Specifically, the air outlet duct 300 can be L-shaped, arc-shaped or S-shaped, as long as it can ensure that at least part of the air outlet duct 300 extends upward in the direction from the air outlet 120 to the air outlet side of the fan 200. It should be noted that “upward” in the technical solution of the present utility model includes vertically upward and obliquely upward.

[0040] The technical solution of the utility model is that an air outlet 120 is provided on the shell 100, and the fan 200 is arranged in the shell 100. The fan 200 has an air inlet side and an air outlet side that are interconnected, and the two ends of the air outlet duct 300 are respectively connected to the air outlet side of the fan 200 and the air outlet 120 of the shell 100. Under the action of the fan 200, the fan 200 can blow the hot air inside the shell 100 to the air outlet 120 through the air outlet duct 300, and discharge it from the air outlet 120 of the shell 100, thereby achieving the effect of heat dissipation of the main component 600 in the shell 100. By providing the air outlet duct 300, on the one hand, it can have a good guiding effect on the hot air in the housing 100, so that the hot air flows to the air outlet 120 through the air outlet duct 300 to effectively dissipate the heat of the main device 600 in the housing 100, and on the other hand, it can make the rain and snow blown in from the air outlet 120 only move in the opposite direction along the air outlet duct 300, so as to prevent the rain and snow from entering the area outside the air outlet duct 300 in the housing 100 through the air outlet 120. By extending at least part of the air outlet duct 300 upward in the direction from the air outlet 120 to the air outlet side of the fan 200, on the one hand, the resistance of the rain and snow to the upward movement after entering the air duct becomes larger, and on the other hand, the power direction provided by the fan 200 is opposite to the direction of the rain and snow, so the operation of the fan 200 further increases the resistance of the rain and snow to enter the housing 100, and even causes the rain and snow to be discharged from the housing 100, so that the protective structure achieves a higher protection level.

[0041] In the embodiments of the present utility model, please refer to Figure 1 and Figure 2 The housing 100 has a side wall, and the air outlet 120 is disposed on the side wall.

[0042] By arranging the air outlet 120 on the side wall of the housing 100 , the risk of the air outlet 120 facing upward to provide convenient conditions for rain and snow to smoothly enter the housing 100 after passing through the air outlet 120 can be reduced.

[0043] Furthermore, if Figure 3 As shown, the air outlet duct 300 includes a first connecting section 310 and a second connecting section 320. The first connecting section 310 is arranged parallel to the air outlet direction of the air outlet 120 and is connected to the air outlet 120; one end of the second connecting section 320 is connected to the first connecting section 310, and the other end of the second connecting section 320 extends upward.

[0044] By providing the air outlet duct 300 with a first connecting section 310 arranged parallel to the air outlet direction of the air outlet 120, the risk of rain and snow flowing downward into the air outlet duct 300 after passing through the air outlet 120 can be reduced. In addition, by connecting one end of the second connecting section 320 with the first connecting section 310 and extending the other end of the second connecting section 320 upward, the resistance of rain and snow traveling in the second connecting section 320 can be increased on the one hand, and the structure of the air outlet duct 300 can be relatively simple, and the path of the air outlet duct 300 can be relatively short, thereby improving the heat dissipation performance of the cabinet using the protective structure. Specifically, the air outlet duct 300 can be L-shaped or arc-shaped.

[0045] Furthermore, if Figure 3 As shown, the first connecting section 310 and the second connecting section 320 are connected by an arc transition.

[0046] By connecting the first connecting section 310 and the second connecting section 320 with an arc transition, it can be ensured that the airflow passes through the connection between the first connecting section 310 and the second connecting section 320 more smoothly, thereby ensuring a good heat dissipation effect.

[0047] In the embodiments of the present utility model, please refer to Figure 1 and Figure 2 The housing 100 further comprises an air inlet 110 , a first louver 410 is installed at the air inlet 110 , and a second louver 420 is installed at the air outlet 120 .

[0048] The air inlet 110 of the housing 100 is used to draw the colder air from the outside into the housing 100 to exchange heat with the main device 600 in the housing 100. The air inlet 110 of the housing 100 can be opened on the side wall or the top of the housing 100. By installing the first louver 410 and the second louver 420 at the air inlet 110 and the air outlet 120 respectively, the protection level at the air inlet 110 and the air outlet 120 can be further improved. It can be understood that different louvers have different protection levels. When the distance between the air inlet 110 and the main device 600 in the housing 100 is far, the protection level of the first louver 410 installed at the air inlet 110 can be higher; when the distance between the air outlet 120 and the main device 600 in the housing 100 is close, in order to ensure a good heat dissipation effect, the protection level of the second louver 420 installed at the air outlet 120 can be lower.

[0049] Compared with the conventional solution in which the second louver 420 is not provided at the air outlet 120, the provision of the second louver 420 at the air outlet 120 in this embodiment can improve the protection level. Before outdoor rain and snow enter the air outlet duct 300, they need to be blocked by the second louver 420, that is, the second louver 420 has a good blocking effect on a part of the rain and snow, thereby further improving the protection level of the protective structure.

[0050] In the embodiments of the present utility model, please refer to Figure 1 , Figure 2 as well as Figure 4 The protective structure further includes a cover plate assembly 500 , which is movably connected to the housing 100 , and the cover plate assembly 500 is installed at the air inlet 110 and / or the air outlet 120 .

[0051] By providing a cover plate assembly 500 at the air inlet 110 and / or the air outlet 120, and the cover plate assembly 500 is movably connected to the housing 100, the cover plate can have a state of opening the air inlet 110 and / or the air outlet 120 and a state of closing the air inlet 110 and / or the air outlet 120 when it moves relative to the housing 100. Specifically, the cover plate assembly 500 can be provided only at the air inlet 110, or only at the air outlet 120, or at both the air inlet 110 and the air outlet 120. When the device to which the protective structure is applied is in a closed state, the cover plate assembly 500 can also close the air inlet 110 and / or the air outlet 120, and at this time, rain and snow can be effectively prevented from entering the interior of the housing 100 of the protective structure. When the device to which the protective structure is applied is in an operating state, the air inlet 110 and the air outlet 120 need to be both in an open state.

[0052] Specifically, when the cover assembly 500 is movably connected to the housing 100, it can be hinged or slidably connected to the housing 100, or the cover assembly 500 can be both hinged relative to the housing 100 and slidable relative to the housing 100. For example, when the cover assembly 500 opens the air inlet 110 and / or the air outlet 120, the cover assembly 500 can first be flipped relative to the housing 100, and then slide relative to the housing 100 so that part of the cover assembly 500 is slidably disposed in the housing 100. The cover assembly 500 can include only one cover plate, or the cover assembly 500 includes a cover plate and a support member 520 that can support the cover plate when the cover plate is opened.

[0053] Furthermore, if Figure 4 As shown, the cover assembly 500 is hinged to the housing 100 .

[0054] Specifically, when the cover plate assembly 500 is hinged to the housing 100, when the cover plate assembly 500 is installed at the air inlet 110, the cover plate assembly 500 can be arranged close to any edge of the air inlet 110. When the cover plate assembly 500 is installed at the air outlet 120, the cover plate assembly 500 can be arranged close to any edge of the air outlet 120. It can be understood that by hingedly connecting the cover plate assembly 500 to the housing 100, when the cover plate opens the air inlet 110 and / or the air outlet 120, the cover plate can act as a retaining wall, thereby blocking rain and snow blowing in the direction of the cover plate, so as to reduce the rain and snow blowing in the direction of the cover plate from entering the housing 100, thereby improving the protection level of the protective structure.

[0055] Taking the cover plate assembly 500 provided at the air outlet 120 as an example, by providing the cover plate assembly 500 at the air outlet 120, the cover plate assembly 500 is hinged to the shell 100, and the cover plate assembly 500 can firstly perform a first-level blocking of part of the external rain and snow, thereby reducing the volume and speed of the rain and snow entering the shell 100; for the rain and snow that the cover plate assembly 500 cannot block, the second shutter 420 in the protective mechanism can perform a second-level blocking, thereby further reducing the volume and speed of the rain and snow entering the shell 100; for the rain and snow that the second shutter 420 cannot block The rain and snow will enter the air outlet duct 300 through the air outlet 120. The speed of the rain and snow entering the air outlet duct 300 is already very low. Since the air outlet duct 300 in the utility model at least partially extends upward in the direction from the air outlet 120 to the air outlet side of the fan 200, the resistance encountered by the rain and snow after entering the air outlet duct 300 is further increased. Under the action of the fan 200, the rain and snow can be easily discharged from the outside of the shell 100, that is, the air outlet duct 300 can perform the third level of blocking for the rain and snow, thereby further improving the protection level of the protection structure.

[0056] Furthermore, if Figure 4 As shown, one side of the cover plate assembly 500 hinged to the housing 100 is close to the top side of the air outlet 120 .

[0057] By placing the side of the cover plate assembly 500 hinged to the housing 100 close to the top of the air outlet 120, the cover plate flips upward when opening the air outlet 120. Since more rain and snow mainly fall vertically downward or obliquely downward from the top, the side of the cover plate assembly 500 hinged to the housing 100 is arranged close to the top side of the air outlet 120, so that the cover plate assembly 500 can block most of the rain and snow.

[0058] In one embodiment, the cover assembly 500 includes a cover body 510 and a support member 520, the cover body 510 is hinged to the shell 100; one end of the support member 520 is movably connected to the shell 100, and the other end is movably connected to the cover body 510 to support the cover body 510 when the cover body 510 is in an open state.

[0059] By hingedly connecting the cover body 510 to the housing 100, the cover body 510 can rotate relative to the housing 100 to open the air inlet 110 and / or the air outlet 120, thereby achieving a better heat dissipation effect when the equipment using the protective structure is operating normally. By movably connecting one end of the support member 520 to the housing 100 and the other end to the cover body 510, and supporting the cover body 510 when the cover body 510 is in the open state, the cover body 510 can be stably maintained in the state of opening the air inlet 110 and / or the air outlet 120, avoiding manual support of the cover body 510.

[0060] Furthermore, in order to ensure the stability of the support member 520, the cover assembly 500 may also include a locking member 540, which is connected to the cover body 510 and is used to lock the support member 520, so as to ensure that the support member 520 is more stable when supporting the cover body 510, and reduce the risk of sliding or rotating. Specifically, the locking member 540 can be a knob lock or a latch lock that can lock the support member 520 to ensure that the support member 520 has a stable supporting state. It should be noted that the knob lock and the latch lock are both common knowledge in the art, so the basic structure and principle of the knob lock and the latch lock will not be described in detail.

[0061] Of course, in other examples, the cover assembly 500 may also only include the cover body 510. When the user opens the cover body 510, the cover assembly 500 can be supported by a separate support rod.

[0062] Furthermore, if Figure 4 As shown, the cover assembly 500 further includes a protective cloth 530 , which is connected to the edge of the cover body 510 .

[0063] The protective cloth 530 is also connected to the edge of the cover body 510, so that the protective cloth 530 can also block rain and snow. In addition, the protective cloth 530 is arranged at the edge of the cover body 510, so that the cover assembly 500 can block rain and snow in at least two different directions, thereby improving the protective effect of the cover assembly 500.

[0064] Specifically, when the top edge of the cover body 510 is hinged to the shell 100, the protective cloth 530 can be arranged on the side edge of the cover body 510; when one side edge of the cover body 510 is hinged to the shell 100, the protective cloth 530 can be arranged on the other side edge or the top edge of the cover body 510, etc.

[0065] The utility model also provides a cabinet, such as Figure 3 As shown, the cabinet includes a main device 600 and a protective structure. The specific structure of the protective structure refers to the above embodiment. Since the cabinet adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the main device 600 is arranged in the shell 100.

[0066] Specifically, the main device 600 may include power devices, transformers, switches, or other devices. By arranging the main device 600 in the housing 100, the main device 600 can be well protected by the housing 100, thereby reducing the risk of the main device 600 being wetted by rain or snow, and also reducing the risk of dust falling on the main device 600 and affecting the normal operation of the main device 600.

[0067] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
