[0001] This utility model relates to the technical field of channel equipment, and in particular to a channel device, switch cabinet and high voltage equipment. Background Technology

[0002] Heat is usually generated during the operation of various devices, and the internal pressure of the devices also increases. Existing devices generally have heat dissipation vents and pressure relief vents installed on them.

[0003] Therefore, the separate placement of heat dissipation vents and pressure relief vents will occupy too much internal space for various channels, which is not conducive to miniaturizing the overall size of the device. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a channel device for merging the channel outlets for heat dissipation and pressure relief, integrating the channel lines for heat dissipation and pressure relief, and realizing the miniaturization of the equipment.

[0007] The connector is configured as an extension, the cover is provided with heat dissipation holes, and at least one side of the cover is connected to the edge of the channel outlet through the connector;

[0008] When the cover is subjected to pressure impact from the inside out from the channel outlet, the connector deforms or displaces, causing the cover to move away from the channel outlet.

[0009] Furthermore, the connector includes a plastic bolt that acts on the cover to connect the cover to the edge of the channel outlet.

[0010] Furthermore, the connector also includes a flexible strip, one end of which is a relatively free end;

[0011] The cover includes a first side and a second side arranged opposite to each other. The first side is connected to the edge of the channel outlet by the plastic bolt. The free end of the flexible strip is connected to the second side, and the other end is connected to the edge of the channel outlet.

[0012] Furthermore, the connector also includes a fixing plate, and the end of the flexible strip on the second side of the cover away from the cover is connected to the edge of the channel outlet through the same fixing plate;

[0013] Alternatively, a fixing plate may be provided on the second side, and the second side may be connected to the edge of the channel outlet through the fixing plate.

[0014] Furthermore, the fixing plate connected to the flexible strip is fixedly connected to the edge of the channel outlet by rigid bolts.

[0015] Furthermore, the connector also includes an extension plate;

[0016] The flexible strips are all connected to the side of the cover through the same extension plate.

[0017] Furthermore, the cover includes a cover plate and multiple side plates;

[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] 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.

[0034] See Figure 1 and Figure 2 This utility model discloses a channel device, including a cover 10 for covering the channel outlet and a connector 20; the connector 20 is configured as an extension member, the cover 10 is provided with heat dissipation holes 101, and at least one side of the cover 10 is connected to the edge of the channel outlet through the connector 20; when the cover 10 is subjected to pressure impact from the inside of the channel outlet from the inside out, the connector 20 deforms or displaces to make the cover 10 move away from the channel outlet.

[0035] In this embodiment, the cover 10 can be a baffle plate or a polyhedron with a regular quadrilateral outer contour. This embodiment uses a regular quadrilateral polyhedron as an example. The number of heat dissipation holes 101 can be multiple, and these holes 101 can be optionally positioned at any location on the cover 10. In this embodiment, the bottom of the cover 10 has a downward-opening cavity that covers the channel outlet to block and seal it.

[0036] Importantly, the cover 10 is connected to the edge of the channel outlet via the connector 20. Because the connector 120 is ductile, when the pressure inside the channel outlet increases, the connector 20 deforms or displaces, creating a gap between the side of the connector 20 and the edge of the channel outlet, which can be used for pressure relief.

[0037] Optionally, the connector 20 includes a plastic bolt that acts on the cover 10 to connect the cover 10 to the edge of the channel outlet.

[0038] In this design, plastic bolts (preferably nylon, not shown in the figure) pass through the side plate of the cover 10 and are screwed to the edge of the channel outlet. The plastic bolts have certain deformation characteristics; when the pressure inside the channel outlet increases, they push the cover 10 outwards. At this time, the plastic bolts adapt by deforming, or they loosen and displace, creating a gap between the cover 10 and the edge of the channel outlet for pressure relief. Simultaneously, the deformation or loosening of the plastic bolts causes displacement of the corresponding side of the cover 10, thereby relieving pressure from the channel outlet and preventing the cover 10 from deforming due to excessive force. Of course, as mentioned above, at least one side of the cover 10 is connected to the edge of the channel outlet via a connector 20. In practical applications, besides the option of connecting one side with a connector 20, the cover 10 can also be connected and fixed to the channel outlet via two or more connectors 20. It is known that each side connected to the channel outlet via a connector 20 will form a gap with the edge of the channel outlet when subjected to internal force; the more gaps, the stronger the pressure relief capacity.

[0039] Optionally, the connector 20 also includes a flexible strip 21, one end of which is a relatively free end; the cover 10 includes a first side and a second side arranged opposite to each other, the first side is connected to the edge of the channel outlet by plastic bolts, the relatively free end of the flexible strip 21 is connected to the second side, and the other end is connected to the edge of the channel outlet.

[0040] The flexible strip 21 can be a thin metal strip, such as an aluminum alloy strip, which is required to deform under a specific force, thereby changing the position of the relative free end. Alternatively, the flexible strip 21 can be a nylon strip, etc.

[0041] Example of the use of flexible strip 21: Multiple flexible strips 21 are spaced along the length of the second side of the lower part of the cover 10. Specifically, the first side is fixed to the edge of the channel outlet by plastic bolts. Under normal circumstances, the lower side of the cover 10 preferably fits against the edge of the channel outlet, and the heat dissipation holes 101 dissipate heat outward. Similarly, the heat dissipation holes 101 can also be used for normal pressure relief. In particular, if the pressure inside the channel outlet increases instantaneously or continuously, the internal air pressure can push the cover 10 away from the channel outlet from the inside out. At this time, in addition to the aforementioned plastic bolts being displaced, the relatively free ends of the flexible strips 21 move with the cover 10, so gaps are generated between the first and second sides and the edge of the channel outlet. This gap also increases the internal space of the channel device, providing pressure relief space. If the cover 10 and the channel outlet are in an up-down position, after the pressure relief is completed, the cover 10 can automatically fall back under gravity or return to its original position under the push of an external force. Another function of the flexible strip 21 is that if the plastic bolts come loose, the flexible strip 21 can pull the cover 10 to prevent the cover 10 from being pushed away too far.

[0042] In other embodiments, the aforementioned second side is connected to the edge of the channel outlet via a flexible strip 21. In other embodiments, the lower part of the regular quadrilateral polyhedron also includes a third and fourth side disposed opposite to each other. The third and fourth sides can be connected to the edge of the channel outlet via the flexible strip 21 or plastic bolts; the arrangement can be freely combined and is not limited here. Furthermore, the first, second, third, and fourth sides can also be connected to the edge of the channel outlet solely via the flexible strip 21.

[0043] Alternatively, the aforementioned flexible strip can be replaced with springs. Ideally, springs should be placed at the four corners, with one end connected to the lower side of the cover 10 and the other end connected to the edge of the channel outlet. If internal pressure is applied, the spring will move away from the channel outlet to release pressure. After the pressure release is complete, the spring will pull the cover 10 back to its original position. Alternatively, the spring can be placed inside the cavity, with one end connected to the inner wall of the cavity, thus concealing the spring effectively.

[0044] Optionally, the connector 20 may also include a fixing plate 22, wherein the end of the flexible strip 21 on the second side of the cover 10 away from the cover 10 is connected to the edge of the channel outlet through the same fixing plate 22; or, the second side is provided with a fixing plate 22, and the second side is connected to the edge of the channel outlet through the fixing plate 22.

[0045] The fixing plate 22 is used to uniformly connect the end of the flexible strip 21 on the second side of the cover 10 away from the cover 10 to one of its own side edges, and the connection is made to the edge of the channel outlet through the fixing plate 22. The fixing plate 22 has a larger contact surface for connection, which is more reliable than directly connecting one end of the flexible strip 21 to the edge of the channel outlet. Of course, in conjunction with the above, if a set of opposite sides of the cover 10 are connected to the edge of the channel outlet, regardless of whether the side is provided with a flexible strip 21, the side can be connected to the edge of the channel outlet through the fixing plate 22. Therefore, the first side in this embodiment can also be provided with a fixing plate 22. The fixing plate 22 is set in the horizontal direction, and the fixing plate 22 of the first side is provided with multiple through holes in the length direction. Plastic bolts pass through the through holes and are screwed to the edge of the channel outlet. The contact surface between the fixing plate 22 of the first side and the edge of the channel outlet is larger, which improves the connection sealing performance. In addition, the plastic bolts acting on the fixing plate 22 prevent deformation and damage to the cover 10.

[0046] Optionally, the fixing plate 22 connected to the flexible strip 21 is fixedly connected to the edge of the channel outlet by rigid bolts.

[0047] In this embodiment, the fixing plate 22 has multiple through holes along its length. Rigid bolts (preferably made of metal, not shown in the figure) pass through the through holes and are screwed to the edge of the channel outlet. As can be seen from the foregoing, the flexible strip 21 can pull the cover 10. Therefore, the fixing plate 22 connected to the flexible strip 21 needs to form a stable connection with the edge of the channel outlet. Thus, in this embodiment, the fixing plate 22 is connected to the edge of the channel outlet by rigid bolts.

[0048] Optionally, the connector 20 also includes an extension plate 23; the flexible strips 21 are all connected to the side of the cover 10 through the same extension plate 23.

[0049] The extension plate 23 is located on the outer side of the lower side of the cover 10 (in the above embodiment, the extension plate 23 is located on the second side). The flexible strip 21 is connected to the side of the cover 10 through the extension plate 23. The extension plate 23 can fit the peripheral edge of the channel outlet to ensure the sealing between the lower side of the cover 10 and the edge of the channel outlet under normal pressure conditions.

[0050] Of course, the aforementioned flexible strip 21, fixed plate 22 and extension plate 23 can be said to be integrated. Assuming that the three are metal, multiple through slots are stamped between the fixed plate 22 and the extension plate 23, and a connecting strip with a very small width is formed between two adjacent through slots. The connecting strip forms the aforementioned flexible strip 21. Preferably, the width of the connecting strip is 1mm-5mm and the length is 1nm-10nm.

[0051] Optionally, the cover 10 includes a cover plate 11 and a plurality of side plates 12; the plurality of side plates 12 are arranged around the side of the cover plate 11, and the side plates 12 are connected to the edge of the channel outlet by a connector 20; heat dissipation holes 101 are provided on the side plates 12.

[0052] The aforementioned regular quadrilateral polyhedron is composed of the cover plate 11 and four side plates 12 in this embodiment. The side plates mentioned above refer to the lower side plates 12. Since the cover plate 11 is directly opposite the channel outlet, the heat dissipation holes 101 in this embodiment are located on the side plates 12 to effectively prevent external dust and other impurities from entering the channel outlet in a straight line.

[0053] See Figure 3 In the design of switchgear, the aforementioned channel devices are commonly used. For example, the switchgear includes a cabinet 30, which has an external drainage channel. In this embodiment, one end of the external drainage channel is a channel outlet, which is located on the wall (preferably the top) of the cabinet 30. The channel device is located at the channel outlet of the cabinet 30. The specific arrangement is described above and will not be repeated here. Alternatively, both ends of an external drainage channel can serve as channel outlets, with one channel device installed at each channel outlet.

[0054] Other high-voltage equipment includes electrical equipment and the aforementioned switchgear. The electrical equipment is housed within cabinet 30 and includes existing equipment assembled from poles, contact boxes, etc., which will not be elaborated upon here. Importantly, the external drainage channel can pass through the electrical equipment or be arranged around its perimeter. The arrangement of the electrical equipment is as needed and will not be listed here.

[0055] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
