[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 8 The explosion venting plate 10 according to the embodiment of the present invention is described. The explosion venting plate 10 includes: a plate body 20 and a flow guide 30. The plate body 20 has a thickness direction A.

[0037] Specifically, if Figure 1-Figure 4 As shown, the guide member 30 is disposed around the outer peripheral side of the plate body 20 , and a drainage channel 31 is disposed on the guide member 30 , and the drainage channel 31 is communicated with the outside.

[0038] Combination Figure 1 and Figure 4 The drainage channel 31 is arranged around the outer peripheral side of the plate body 20, and the drainage channel 31 is suitable for communicating with the outside. The explosion-proof plate 10 is arranged on the top of the box body 100 and exposed to the outside air. Rainwater or moisture in the air will condense into water droplets and gather on the plate body 20. The design of the drainage channel 31 on the guide member 30 can make the water droplets or rainwater on the plate body 20 flow into the drainage channel 31. The drainage channel 31 is connected to the outside, so that the liquid collected in the drainage channel 31 can flow to the outside, thereby ensuring the dryness of the explosion-proof plate 10 and the box body 100.

[0039] According to the explosion-proof plate 10 of the embodiment of the utility model, a flow guide 30 is arranged on the outer peripheral side of the plate body 20, and a drainage channel 31 is arranged on the flow guide 30. The drainage channel 31 plays a role of guiding and draining water, so that the liquid gathered on the plate body 20 can flow into the drainage channel 31 and flow to the outside through the drainage channel 31, thereby preventing the accumulated water from accumulating on the explosion-proof plate 10 for a long time and penetrating from the edge of the explosion-proof plate 10 into the inside of the box body 100, thereby avoiding water ingress at the sealing part of the explosion-proof plate 10 resulting in failure of protection of the box body 100. The arrangement of the flow guide 30 can effectively improve the waterproof performance of the explosion-proof plate 10 to the box body 100.

[0040] According to some embodiments of the present invention, Figure 4 As shown, the drainage channel 31 includes a drainage groove 32, which is formed on the flow guide 30 and extends along the circumference of the plate body 20. The drainage groove 32 is arranged around the outer peripheral side of the plate body 20 and extends along the circumference of the plate body 20. The drainage groove 32 is arranged below the plate body 20 along the thickness direction A of the plate body 20, so that the accumulated water on the plate body 20 can flow smoothly into the drainage groove 32. Therefore, the arrangement of the drainage groove 32 is suitable for accommodating the liquid accumulated on the plate body 20, and the drainage groove 32 can guide and store the accumulated water. The extension of the drainage groove 32 along the circumference of the plate body 20 is conducive to the comprehensive distribution of the drainage groove 32 around the plate body 20, and can also increase the volume of the drainage groove 32, increase the capacity of the drainage groove 32, and thus improve the drainage efficiency of the drainage groove 32.

[0041] According to some embodiments of the present invention, Figure 5-Figure 7 As shown, the guide member 30 includes: a first side plate 34, a second side plate 35 and a third side plate 36. The first side plate 34 and the second side plate 35 are spaced apart in a direction perpendicular to the central axis of the plate body 20. The first side plate 34 is arranged on a side of the second side plate 35 adjacent to the center of the plate body 20. The plate body 20 is connected to the first side plate 34. The third side plate 36 is connected to the first side plate 34 and the second side plate 35 on a side away from the plate body 20 along the thickness direction A of the plate body 20. The third side plate 36, the first side plate 34 and the second side plate 35 define a drainage groove 32.

[0042] The first side plate 34, the second side plate 35 and the third side plate 36 all extend along the circumference of the plate body 20. The first side plate 34 is fixedly connected to the edge of one side surface of the plate body 20 along the thickness direction A. The first side plate 34 is arranged around the edge of the plate body 20. The second side plate 35 is arranged at the periphery of the first side plate 34 away from the central axis of the plate body 20. There is a certain distance between the first side plate 34 and the second side plate 35. The third side plate 36 is arranged parallel to the thickness direction A of the plate body 20. One end of the third side plate 36 adjacent to the central axis of the plate body 20 is suitable for connecting with one end of the first side plate 34 along the thickness direction A of the plate body 20. The other end of the second side plate 35 away from the central axis of the plate body 20 is suitable for connecting with one end of the second side plate 35 along the thickness direction A of the plate body 20. The drainage groove 32 defined by the third side plate 36, the first side plate 34 and the second side plate 35 is located at the lower side of the plate body 20 along the thickness direction A. The drainage groove 32 is openly arranged at the upper side of the thickness direction A of the plate body 20.

[0043] Thus, the first side panel 34, the second side panel 35 and the third side panel 36 jointly define a drainage groove 32. The first side panel 34 is suitable for being connected to the panel body 20. The second side panel 35 and the third side panel 36 can seal the edges and corners of the explosion-proof panel 10, which can not only increase the overall structural strength of the explosion-proof panel 10, but also limit the accumulated water in the drainage groove 32 to prevent the accumulated water from penetrating from the edges and corners into the interior of the box body 100, thereby improving the sealing and waterproof performance of the explosion-proof panel 10.

[0044] According to some embodiments of the present invention, Figure 6 As shown, the first side panel 34 includes a first sub-panel 341 and a second sub-panel 342, one end of the first sub-panel 341 is connected to one end of the second sub-panel 342, the other end of the first sub-panel 341 is connected to the third side panel 36, the other end of the second sub-panel 342 extends horizontally toward the second side panel 35, and the panel body 20 is connected to the second sub-panel 342.

[0045] The first sub-plate 341 is arranged parallel to the thickness direction A of the plate body 20, the second sub-plate 342 is arranged perpendicular to the thickness direction A of the plate body 20, that is, the second sub-plate 342 is arranged parallel to the plate body 20, the second sub-plate 342 is opposite to the third side plate 36 along the thickness direction A of the plate body 20, and the side surface of the second sub-plate 342 away from the third side plate 36 along the thickness direction A of the plate body 20 is suitable for connecting with the edge of the side surface of the plate body 20, one end of the first sub-plate 341 along the thickness direction A of the plate body 20 is connected to one end of the second sub-plate 342, and the other end of the first sub-plate 341 along the thickness direction A of the plate body 20 is connected to one end of the third side plate 36. Therefore, the design of the first sub-plate 341 and the second sub-plate 342 of the first side plate 34 is conducive to ensuring the connection strength between the flow guide 30 and the plate body 20, thereby improving the overall structural strength of the explosion venting plate 10 and extending the service life of the explosion venting plate 10.

[0046] According to some embodiments of the present invention, Figure 6 As shown, the distance between the second sub-plate 342 and the third side plate 36 is greater than or equal to the distance between the upper end surface of the second side plate 35 and the third side plate 36. The spacing between the second sub-plate 342 and the third side plate 36 along the thickness direction A of the plate body 20 is greater than or equal to the distance between the upper end surface of the second side plate 35 and the third side plate 36 along the thickness direction A of the plate body 20, so that the drainage groove 32 is always not higher than the plate body 20 in the thickness direction A of the plate body 20. Therefore, the distance between the second sub-plate 342 and the third side plate 36 is greater than or equal to the distance between the upper end surface of the second side plate 35 and the third side plate 36, that is, the height of the drainage groove 32 is not higher than the height of the plate body 20, which can avoid the risk of the plate body 20 being soaked when there is too much water in the drainage groove 32, improve the safety performance of the explosion venting plate 10, and extend the service life of the explosion venting plate 10.

[0047] According to some embodiments of the present invention, Figure 8As shown, the plate body 20 includes: a body portion 21 and a connecting portion 22, the connecting portion 22 is arranged on the outer peripheral side of the body portion 21, and the connecting portion 22 is connected to the side of the second sub-plate 342 away from the third side plate 36. The connecting portion 22 is arranged around the edges of the body portion 21, and the connecting portion 22 is suitable for connecting with the guide member 30. The lower side surface of the connecting portion 22 along the thickness direction A of the plate body 20 is connected to the upper side surface of the second sub-plate 342 along the thickness direction A of the plate body 20, and the third side plate 36 is arranged spaced apart from the connecting portion 22 along the thickness direction A of the plate body 20. Therefore, the main body 21 mainly plays a protective role for the interior of the box body 100, and the connecting part 22 is suitable for connecting the board body 20 with the guide member 30. The accumulated water gathered on the main body 21 flows to the surroundings of the main body 21 and flows through the connecting part 22 and finally falls into the drainage groove 32. The setting of the connecting part 22 can also enhance the connection strength between the board body 20 and the guide member 30, facilitate the assembly between the board body 20 and the guide member 30, and reduce the difficulty of assembling the board body 20.

[0048] According to some embodiments of the present invention, Figure 7 As shown, the drainage channel 31 also includes at least one drainage hole 33, which is formed on the guide member 30, and the drainage groove 32 is connected to the outside through the drainage hole 33. The drainage hole 33 is provided on the second side plate 35 of the guide member 30, and the drainage hole 33 is provided through the second side plate 35. There can be multiple drainage holes 33, and multiple drainage holes 33 are arranged on the second side plate 35 at intervals along the extension direction of the second side plate 35. Therefore, the arrangement of the drainage hole 33 facilitates the drainage groove 32 to be connected to the outside so that the liquid in the drainage groove 32 flows to the outside through the drainage hole 33, effectively drains the accumulated water, and prevents the accumulated water from accumulating for a long time and penetrating into the box body 100, so as to achieve safe drainage. The arrangement of multiple drainage holes 33 can effectively improve the drainage efficiency of the drainage channel 31.

[0049] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the invention also includes a reinforcement member 40, which is arranged on a side of the guide member 30 away from the plate body 20 along a direction perpendicular to the central axis of the plate body 20. The reinforcement member 40 is arranged on the outer peripheral side of the guide member 30 and connected to the guide member 30, and a side surface of the reinforcement member 40 adjacent to the central axis of the plate body 20 is suitable for connecting with a side surface of the second side plate 35 of the guide member 30 away from the central axis of the plate body 20. Therefore, the arrangement of the reinforcement member 40 is conducive to improving the structural strength of the guide member 30, and the reinforcement member 40 can protect the outer peripheral side of the plate body 20 and the guide member 30, and can effectively prevent the guide member 30 from being deformed, thereby extending the service life of the plate body 20 and the guide member 30.

[0050] According to some embodiments of the present invention, Figure 1-Figure 3As shown, the reinforcement member 40 is arranged around the outer peripheral side of the explosion venting plate 10. The reinforcement member 40 is arranged around the outer peripheral side of the explosion venting plate 10, which is conducive to providing comprehensive protection for the explosion venting plate 10 and improving the overall structural strength of the explosion venting plate 10. When the explosion venting plate 10 is installed, the provision of the reinforcement member 40 is also conducive to the assembly of the explosion venting plate 10, which can prevent the outer peripheral edge of the explosion venting plate 10 from being deformed when being squeezed or collided, and reduce the impact on the surface flatness of the explosion venting plate 10. Therefore, the reinforcement member 40 is arranged around the outer peripheral side of the explosion venting plate 10, which is conducive to the reinforcement member 40 providing more comprehensive protection for the explosion venting plate 10, enhancing the structural strength of the explosion venting plate 10, reducing the deformation of the explosion venting plate 10 that may occur during assembly, thereby protecting the function of the explosion venting plate 10 from failure.

[0051] According to some embodiments of the present invention, the reinforcement 40 is welded to the guide 30. The side surface of the reinforcement 40 adjacent to the central axis of the plate body 20 is suitable for being connected to the side surface of the second side plate 35 of the guide 30 away from the central axis of the plate body 20 by welding. The welding connection has the advantages of high connection strength, no need to use extra connectors, high welded parts yield rate and low production cost. Therefore, the welding connection between the reinforcement 40 and the guide 30 is conducive to improving the connection strength between the reinforcement 40 and the guide 30, reducing the connection difficulty between the reinforcement 40 and the guide 30, and enhancing the overall structural strength of the explosion venting plate 10.

[0052] According to some embodiments of the utility model, the plate body 20 is bolted to the guide member 30. The plate body 20 is connected to the first side plate 34 of the guide member 30 by means of bolts. The bolt connection is detachable, and the bolt connection allows the disassembly and reassembly of the parts, which is convenient for later replacement and maintenance; the bolt connection is adjustable, and the tightness of the connection between the plate body 20 and the guide member 30 can be easily adjusted by rotating the bolts, which is convenient for dealing with looseness or excessive tightness; the bolts are highly standardized and widely used in various mechanical parts and structures, which is conducive to reducing the production cost of the explosion venting plate 10. Therefore, the bolt connection between the plate body 20 and the guide member 30 facilitates the assembly between the plate body 20 and the guide member 30, and also facilitates the maintenance and replacement of the plate body 20 and the guide member 30, which can extend the service life of the explosion venting plate 10 and reduce the production cost of the explosion venting plate 10.

[0053] According to the second embodiment of the utility model, the box 100 is as follows: Figure 1-Figure 3As shown, the box body 100 includes: a box body 50 and at least one explosion venting plate 10, at least one mounting hole is formed on the top of the box body 50, and the explosion venting plate 10 is arranged at the mounting hole. The explosion venting plate 10 is the explosion venting plate 10 according to the embodiment of the first aspect of the utility model. The box body 100 has a height direction B, a width direction C and a length direction D. The box body 50 is formed with a mounting hole that penetrates the top of the box body 50 along the height direction B of the box body 100, and the explosion venting plate 10 is arranged at the top of the box body 50 along the height direction B of the box body 100. The explosion venting plate 10 is installed at the mounting hole to seal the inside of the box body 100. The front side of the box body 50 along the width direction C is an open structure or a structure that can be opened and closed.

[0054] According to the box body 100 of the embodiment of the utility model, the explosion venting plate 10 is installed on the top of the box body 50. By using the explosion venting plate 10 described in this embodiment, it is beneficial to improve the sealing performance of the installation of the explosion venting plate 10 and the box body 50, improve the drainage effect of the explosion venting plate 10, effectively prevent water from entering the interior of the box body 50, and protect the internal structure of the box body 50.

[0055] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, there are multiple explosion venting panels 10, and the multiple explosion venting panels 10 are arranged at intervals along the length direction D of the box body 50. The multiple explosion venting panels 10 are arranged at the rear side of the top of the box body 50 along the width direction C of the box body 100, and a reinforcement member 40 is arranged between adjacent explosion venting panels 10. Therefore, the arrangement of multiple explosion venting panels 10 is conducive to improving the drainage effect of the top of the box body 50, and is also convenient for assembling the explosion venting panels 10 on the box body 50. The explosion venting panels 10 are arranged at the rear side of the box body 50 along the width direction C of the box body 100, so that the pressure on the explosion venting panels 10 can be discharged backwards. The arrangement of multiple explosion venting panels 10 can make the pressure evenly distributed, reduce the force on each explosion venting panel 10, and improve the safety of the box body 100 during use.

[0056] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the explosion venting plate 10 includes: a first reinforcement 41 and a second reinforcement 42, the first reinforcement 41 is arranged on the outer peripheral side of multiple explosion venting plates 10, and at least one through hole 411 is provided on the first reinforcement 41, and the through hole 411 is connected to the drainage hole 33 of the explosion venting plate 10, and the second reinforcement 42 is arranged between two adjacent explosion venting plates 10.

[0057] The first reinforcement 41 is arranged around the four sides of the plurality of explosion relief panels 10, and the through hole 411 on the first reinforcement 41 is arranged through the side wall of the reinforcement 40, and the plurality of through holes 411 are arranged at intervals along the extension direction of the first reinforcement 41, and the through holes 411 are arranged opposite to and connected with the drainage holes 33 on the explosion relief panels 10. The second reinforcement 42 extends along the width direction C of the box body 100, and the second reinforcement 42 is arranged at intervals along the length direction D of the box body 100, and the second reinforcement 42 is respectively welded to the second side panels 35 of two adjacent explosion relief panels 10 on both sides along the length direction D of the box body 100. The first reinforcement 41 can be a separate structure independent of the box body 50, or it can be configured as a whole with the box body 50, forming a part of the top beam of the box body 50.

[0058] Therefore, the first reinforcement 41 is arranged around the outer periphery of the plurality of explosion venting panels 10, which is beneficial to protecting the outer periphery of the plurality of explosion venting panels 10 and improving the structural strength of the outer periphery of the explosion venting panels 10. The second reinforcement 42 is arranged between two adjacent explosion venting panels 10 and can also improve the connection strength between the plurality of explosion venting panels 10. The through hole 411 on the first reinforcement 41 is connected with the drainage hole 33 of the explosion venting panel 10, so that the accumulated water in the drainage groove 32 flows out of the top of the box body 100 through the drainage hole 33 and the through hole 411, effectively avoiding the risk of the top of the box body 100 being soaked in water for a long time, improving the drainage performance of the explosion venting panel 10, and extending the service life of the explosion venting panel 10 and the box body 100.

[0059] According to some embodiments of the present invention, Figure 4 As shown, it also includes: a connecting pipe 43, which is arranged between the through hole 411 and the drain hole 33 to connect the through hole 411 and the drain hole 33. The connecting pipe is suitable for connecting the through hole 411 and the drain hole 33, so that the accumulated water in the drain groove 32 flows to the outside through the drain hole 33, the connecting pipe and the through hole 411 in sequence. Therefore, the setting of the connecting pipe can limit the flow path of the accumulated water, prevent the accumulated water from accumulating inside the first reinforcement 41, facilitate the timely removal of the accumulated water in the drain groove 32, and prevent the accumulated water from accumulating for a long time and penetrating from the gap of the explosion venting plate 10 into the box body 100, causing rust inside the box body 100, effectively improving the sealing performance of the explosion venting plate 10 to the box body 100, preventing the penetration of water, and extending the service life of the box body 100.
