Description

Technical Field

[0001] The utility model belongs to the technical field of helipads, and particularly relates to a quick - installable helipad deck. Background Art

[0002] The helipad deck is the load - bearing and operating surface of a helipad, which is used to support the weight of a helicopter and ensure its safe take - off and landing. It is an important part of a helipad.

[0003] In the prior art, some helipad decks do not have corresponding air - guiding channels and air - guiding structures. When a helicopter takes off and lands, the high - speed airflow generated by the propeller directly hits the panel and cannot be effectively guided, which easily causes large vibrations of the deck. Continuous vibrations may cause problems such as loosening of the connection structure, affecting the stability of the deck and the safety of take - off and landing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick - installable helipad deck for the above - mentioned problems existing in the prior art.

[0005] To achieve the purpose of the utility model, the following technical solutions can be adopted:

[0006] A quick - installable helipad deck includes a panel, a base plate integrally connected, and a support plate located between the panel and the base plate. A cavity channel is formed between adjacent support plates. Adjacent panels are detachably connected by a quick - installation structure. The panel is provided with ventilation holes communicating with the cavity channel, and a wind - guiding structure is detachably arranged in the cavity channel for guiding the high - speed airflow blown into the ventilation holes to the end of the cavity channel for discharge.

[0007] The main part of the quick - installable helipad deck of the utility model is the integrally formed panel, base plate and support plate, with high overall structural strength, reducing the generation of joints and improving the service life of the deck; the cavity channel runs through along the length direction, providing good ventilation conditions for the space between the panel and the base plate, and achieving the effect of light weight at the same time; the quick - installation structure is used to realize the detachable connection between the panels, and then achieve the detachable docking between adjacent decks, facilitating disassembly, installation and later maintenance and replacement; the ventilation holes allow the high - speed airflow generated during helicopter take - off and landing to enter the cavity channel, and the wind - guiding structure in the channel is used to guide these airflows and discharge them from one end of the cavity channel, ensuring the smooth flow of the airflow, which is beneficial to reducing the vibration brought by the airflow to the deck and improving the landing safety performance. At the same time, the guided airflow maintains a relatively high wind speed intensity, which helps to blow out the accumulated water, moisture, debris, etc. in the cavity channel, extending the service life of the deck. The detachable setting method also ensures flexible detachable performance, facilitating the disassembly, installation and maintenance of the wind - guiding structure.

[0008] In the above-mentioned quick-installation apron deck, the quick-installation structure includes C-shaped connecting ears and S-shaped connecting ears respectively arranged on both sides of the panel, and the C-shaped connecting ears and S-shaped connecting ears of adjacent panels are engaged and matched.

[0009] The C-shaped connecting ears and S-shaped connecting ears are respectively arranged on both sides of the panel, and their shape designs cleverly achieve the engagement and matching. When adjacent panels need to be connected, the S-shaped connecting ear of one panel will naturally be inserted into the C-shaped connecting ear of another panel to form a tight engagement state. This engagement and matching ensures the firm and reliable connection between the panels, and allows for the quick installation and disassembly of the panels, facilitating later maintenance and adjustment.

[0010] In the above-mentioned quick-installation apron deck, the docking opening of the C-shaped connecting ear is inclined upward, including a lower arc portion with an arc-shaped depression and an upper horizontal portion extending horizontally. The lower arc portion and the upper horizontal portion are integrally connected, and the docking opening is formed therebetween. The S-shaped connecting ear is inserted into the docking opening.

[0011] The inclined upward docking opening enables the S-shaped connecting ear to naturally slide into along the inclination angle of the opening when inserted, reducing the resistance and difficulty during insertion. Once the S-shaped connecting ear is completely inserted into the docking opening, due to the inclined design of the opening, the S-shaped connecting ear will be effectively locked inside the C-shaped connecting ear and is not easy to fall off, thus enhancing the stability of the connection. The lower arc portion and the upper horizontal portion of the C-shaped connecting ear form a solid structure through integral connection and can withstand forces from all directions. When the S-shaped connecting ear is inserted into the docking opening and engages with the C-shaped connecting ear, the contact area between the two increases, dispersing the stress points and further enhancing the strength and stability of the connection.

[0012] In the above-mentioned quick-installation apron deck, the S-shaped connecting ear includes a connecting portion integrally connected to the panel and a bent limiting portion at the front end of the connecting portion. The bent limiting portion is L-shaped, and a docking step is formed at the upper end. The bent limiting portion is inserted between the lower arc portion and the upper horizontal portion, the upper horizontal portion is located above the docking step, and the front end of the lower arc portion is higher than the bottom of the bent limiting portion.

[0013] When the bent limiting portion is inserted between the lower arc portion and the upper horizontal portion, the upper horizontal portion is exactly located above the docking step, and the front end of the lower arc portion is higher than the bottom of the bent limiting portion, ensuring that the S-shaped connecting ear can be clamped by the forces from the upper and lower directions after insertion, thus achieving a stable engagement connection. The front end of the lower arc portion is hooked upward to form a horizontal limit, but allows the S-shaped connecting ear and the C-shaped connecting ear to rotate relative to each other in the vertical direction, ensuring flexible and smooth disassembly and assembly.

[0014] In the above-mentioned quick-install apron deck, a limiting protrusion is provided on the bottom surface of the front end of the upper cross section, the limiting protrusion is in contact with the horizontal step surface of the docking step, and a clearance area is formed between the inner side of the limiting protrusion and the bottom surface of the upper cross section.

[0015] The limiting protrusion is used to impose a downward limit on the docking step, so that the bent limiting portion remains in the lower arc portion to ensure a stable connection; the yield area allows the S-shaped connecting ear to have a certain adjustment space during the insertion process, that is, the S-shaped connecting ear and the C-shaped connecting ear have a certain rotation allowable space in the horizontal direction, especially allowing the far end of the S-shaped connecting ear to rotate downward relatively appropriately, making the installation more flexible and convenient, and also avoiding the collapse of the quick-install structure.

[0016] In the above-mentioned quick-install apron deck, the wind guide structure includes two parallel straight connecting plates, and mounting cross bars are distributed between the connecting plates along the length direction. Wind guide plates inclined toward one end of the cavity channel are fixed on the mounting cross bars. The wind guide plates correspond to the air holes one by one, and their upper ends are attached to the bottom surface of the panel, and a wind gap is formed between the lower ends and the base plate. A detachable structure is provided between the connecting plates and the support plates.

[0017] The two straight connecting plates are parallel to each other, and mounting cross bars are provided between the connecting plates. These cross bars provide fixing points for the installation of the air guide plates. The air guide plates are fixed on the mounting cross bars and tilted toward one end of the cavity channel, so that the high-speed airflow blown in from the air vents can smoothly flow to the end of the cavity channel along the guiding direction of the air guide plates; the air guide plates are arranged one by one under the ventilation holes, ensuring that the airflow blown in from each air vent can be effectively guided, reducing the turbulence and eddy current of the airflow, and reducing noise and vibration; the lower end of the air guide plate is not in contact with the base plate, and a wind passing gap is formed therebetween, and this gap allows the airflow guided by each air vent to flow smoothly backward in the same direction, ensuring a smooth guided ventilation effect; the detachable structure makes the air guide structure easy to disassemble and replace, and is also easy to adjust the angle and position of the air guide plate according to actual needs to achieve the best ventilation and wind guiding effect.

[0018] In the above-mentioned quick-install apron deck, the mounting cross bar includes an inclined mounting surface, the inclined mounting surface is provided with mounting screw holes, the back side of the wind deflector is in contact with the inclined mounting surface, the mounting bolts pass through the mounting through holes of the wind deflector and are engaged and fixed with the mounting screw holes, and the inclination directions of the wind deflectors are consistent, or are inclined toward the middle respectively.

[0019] The inclined mounting surface provides good support for the air deflector. The air deflector and the mounting crossbar are firmly and flexibly fixed through mounting bolts, which is convenient for disassembly and assembly. The inclined direction can be designed according to actual needs. As a feasible solution, all the air deflectors incline towards one end of the cavity channel to guide the air flow smoothly to the other end. Another design can be bounded by a certain position in the length direction, and the inclined directions of the air deflectors on the left and right sides are opposite, but both incline towards this boundary to achieve the effect of orderly pouring the air flow to both sides.

[0020] In the above-mentioned quick-installation helipad deck, the detachable structure includes a card slot provided on the side surface of the support plate. The thickness of the connecting plate is adapted to the width of the card slot, and the outer side of the connecting plate is clamped in the card slot. At least two linear clamping bodies are fixed on the side surface of the support plate and protrude towards the cavity channel along the length direction, and the card slot is formed between the clamping bodies.

[0021] The card slot is formed by two inwardly protruding linear clamping bodies. Of course, it can also be directly formed by opening on the support plate. However, the way formed by the clamping bodies has less impact on the structural strength of the support plate and is a better solution. The outer side of the connecting plate is designed with a structure matching the card slot. Through a simple clamping action, the connecting plate can be fixed on the support plate, with flexible disassembly and assembly and firm connection.

[0022] In the above-mentioned quick-installation helipad deck, a positioning structure is provided at the end of the connecting plate. The positioning structure includes a positioning pin hole penetrating through the connecting plate, and a positioning pin shaft is inserted into the positioning pin hole. The positioning pin shaft is in contact with and limited by the outer end surface of at least one of the clamping body, the support plate, the base plate and the panel.

[0023] The positioning structure is used for positioning after the air guiding structure is installed, preventing axial movement, and ensuring that each air deflector and the ventilation hole are corresponding. It is specifically realized through the positioning pin shaft. The positioning pin shaft is inserted into the positioning pin hole and is also in contact with and limited by the outer end surface of at least one component of the clamping body, the support plate, the base plate and the panel, having a good axial limiting effect, ensuring the accuracy and stability of the connecting plate during the connection process, preventing displacement or loosening caused by improper installation or external force, and in addition, the positioning realized through the positioning pin shaft has flexible detachable properties, facilitating quick positioning and fixing, helping to improve work efficiency, and reducing installation difficulty and cost.

[0024] In the above-mentioned quick-installation helipad deck, a number of tooth-shaped anti-slip strips are provided on the panel. The tooth-shaped anti-slip strips are distributed along the width direction of the panel and extend along the length direction. The support plate is inclined, and the inclined directions of adjacent support plates are opposite, and the number of the support plates is an even number.

[0025] The main purpose of the serrated anti-skid strips is to increase the friction on the panel surface to prevent aircraft or personnel on the apron from slipping when moving, thereby improving safety in use; the support plates are designed to be inclined, and the inclination directions of adjacent support plates are opposite, which helps to disperse the weight and pressure borne by the deck and improve the stability and load-bearing capacity of the structure. At the same time, the number of support plates is an even number, which helps to maintain the overall balance and symmetry of the deck and prevent deflection or deformation during use.

[0026] As an optimization, a corresponding fixing structure, such as a bolt structure, is provided between the base plate and the mounting table, which will not be elaborated in detail.

[0027] Compared with the prior art, the utility model mainly has the following advantages:

[0028] 1. The quick-install structure is used to achieve detachable docking between adjacent decks, which is convenient for disassembly and assembly as well as subsequent maintenance and replacement; the air guide structure in the cavity channel is used to guide the airflow and discharge it from one end of the cavity channel, ensuring the smooth flow of the airflow, which is beneficial to reduce the vibration of the deck caused by the airflow and improve the landing safety performance. At the same time, the airflow after guidance maintains a large wind speed intensity, which helps to blow out the accumulated water, moisture, debris, etc. in the cavity channel, and extend the service life of the deck. The detachable setting method also ensures flexible detachability, which is convenient for the disassembly and maintenance of the air guide structure.

[0029] 2. The upwardly inclined docking opening allows the S-shaped connecting ear to slide in naturally along the inclined angle of the opening during insertion, reducing the resistance and difficulty during insertion. Once the S-shaped connecting ear is fully inserted into the docking opening, due to the inclined design of the opening, the S-shaped connecting ear will be effectively locked in the C-shaped connecting ear and will not fall off easily, thereby enhancing the stability of the connection.

[0030] 3. The limiting protrusion is used to impose a downward limit on the docking step, so that the bending limit portion remains in the lower arc portion to ensure a stable connection; the clearance area allows the far end of the S-shaped connecting ear to rotate downward relatively appropriately, making the installation more flexible and convenient, and also avoiding the collapse of the quick-install structure.

[0031] 4. The air guide plates are arranged one by one under the ventilation holes, ensuring that the airflow blown into each ventilation hole can be effectively guided, reducing the turbulence and eddy current of the airflow, and reducing noise and vibration; the detachable structure makes the air guide structure easy to disassemble and replace, and it is also convenient to adjust the angle and position of the air guide plate according to actual needs to achieve the best ventilation and wind guiding effect.

[0032] 5. The card slot is formed by a linear card body, which has less impact on the structural strength of the support plate. The connecting plate is fixed on the support plate by card connection, and the disassembly and assembly are flexible and the connection is stable.

[0033] 6. The positioning structure is used to position the air guide structure after it is installed to prevent axial movement and ensure that each air guide plate and vent hole remain corresponding. It is specifically achieved through the positioning pin shaft, which ensures the accuracy and stability of the connecting plate during the connection process and prevents displacement or loosening due to improper installation or external force. In addition, the positioning is flexible and removable, which is convenient for quick positioning and fixation, helps to improve work efficiency and reduce installation difficulty and cost.

[0034] 7. The support plates are inclined, and the inclination directions of adjacent support plates are opposite, which helps to disperse the weight and pressure borne by the deck and improve the stability and load-bearing capacity of the structure. At the same time, the number of support plates is an even number, which helps to maintain the overall balance and symmetry of the deck and prevent deflection or deformation during use.

DETAILED DESCRIPTION

[0042] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0043] Specific implementation examples Figures 1-6 As shown, the quick-install apron deck comprises an integrally connected panel 1, a base plate 2 and a support plate 3 between the panel 1 and the base plate 2, a cavity channel 31 is formed between adjacent support plates 3, and adjacent panels 1 are detachably connected via a quick-install structure 4, a vent hole 11 connected to the cavity channel 31 is provided on the panel 1, and a wind guide structure 5 is detachably provided in the cavity channel 31 for guiding the high-speed airflow blown into the vent hole 11 to the end of the cavity channel 31 for discharge.

[0044] Specifically, the main part of the apron deck is an integrally formed panel 1, a base plate 2 and a support plate 3, with high overall structural strength, reduced seams, and improved service life of the deck; the cavity channel 31 is arranged to penetrate along the length direction, providing good ventilation conditions for the space between the panel 1 and the base plate 2, while achieving a lightweight effect; the quick-install structure 4 is used to achieve a detachable connection between the panels 1, and then to achieve a detachable docking between adjacent decks, which is convenient for disassembly and subsequent maintenance and replacement; the vent 11 allows the high-speed airflow generated during helicopter takeoff and landing to enter the cavity channel 31, and the wind guide structure 5 in the channel is used to guide these airflows and discharge them from one end of the cavity channel 31, ensuring smooth flow of the airflow, which is beneficial to reducing the vibration of the airflow on the deck and improving the landing safety performance. At the same time, the airflow after guidance maintains a large wind speed intensity, which helps to blow out the accumulated water, moisture, debris, etc. in the cavity channel 31, and extend the service life of the deck. The detachable arrangement also ensures flexible disassembly, which is convenient for the disassembly and maintenance of the wind guide structure 5.

[0045] like Figure 1 , 3 As shown, the quick-install structure 4 includes a C-shaped connecting ear 41 and an S-shaped connecting ear 42 respectively arranged on both sides of the panel 1, and the C-shaped connecting ear 41 and the S-shaped connecting ear 42 of the adjacent panels 1 are engaged with each other. The docking opening 50 of the C-shaped connecting ear 41 is inclined upward, and includes an arc-shaped concave lower arc portion 43 and a laterally extending upper transverse portion 44. The lower arc portion 43 and the upper transverse portion 44 are integrally connected, and a docking opening 50 is formed therebetween. The S-shaped connecting ear 42 is inserted into the docking opening 50. The S-shaped connecting ear 42 includes a connecting portion 45 integrally connected to the panel 1, and a bending limit portion 46 located at the front end of the connecting portion 45. The bending limit portion 46 is L-shaped, and a docking step 47 is formed at the upper end. The bending limit portion 46 extends and inserts between the lower arc portion 43 and the upper transverse portion 44. The upper transverse portion 44 is located above the docking step 47, and the front end of the lower arc portion 43 is higher than the bottom of the bending limit portion 46. A limiting protrusion 48 is provided on the bottom surface of the front end of the upper transverse portion 44 . The limiting protrusion 48 is in contact with the horizontal step surface of the docking step 47 . A clearance area 49 is formed between the inner side of the limiting protrusion 48 and the bottom surface of the upper transverse portion 44 .

[0046] Specifically, the C-shaped connecting ear 41 and the S-shaped connecting ear 42 are respectively arranged on both sides of the panel 1, and their shape designs ingeniously achieve a biting fit. When adjacent panels 1 need to be connected, the S-shaped connecting ear 42 of one panel 1 will naturally be inserted into the C-shaped connecting ear 41 of another panel 1 to form a tight biting state. This biting fit ensures a firm and reliable connection between the panels 1 and allows for quick installation and disassembly between the panels 1, facilitating later maintenance and adjustment. The docking opening 50 that slopes upward enables the S-shaped connecting ear 42 to naturally slide in along the inclination angle of the opening when inserted, reducing the resistance and difficulty during insertion. Once the S-shaped connecting ear 42 is fully inserted into the docking opening 50, due to the inclined design of the opening, the S-shaped connecting ear 42 will be effectively locked within the C-shaped connecting ear 41 and is not easily detached, thereby enhancing the stability of the connection. The lower arc portion 43 and the upper horizontal portion 44 of the C-shaped connecting ear 41 are integrally connected to form a solid structure that can withstand forces from all directions. When the S-shaped connecting ear 42 is inserted into the docking opening 50 and bites with the C-shaped connecting ear 41, the contact area between the two increases, dispersing the stress points and further enhancing the strength and stability of the connection. When the bending limiting portion 46 is inserted between the lower arc portion 43 and the upper horizontal portion 44, the upper horizontal portion 44 is exactly above the docking step 47, and the front end of the lower arc portion 43 is higher than the bottom of the bending limiting portion 46, ensuring that the S-shaped connecting ear 42 can be clamped by the clamping forces from both the upper and lower directions after insertion, thereby achieving a stable biting connection. The front end of the lower arc portion 43 is hooked upward to form a limit in the horizontal direction, but allows the S-shaped connecting ear 42 and the C-shaped connecting ear 41 to rotate relative to each other in the vertical direction, ensuring flexible and smooth disassembly and assembly. The limiting protrusion 48 is used to apply a downward limit to the docking step 47, keeping the bending limiting portion 46 within the lower arc portion and ensuring a stable connection; the relief area 49 allows the S-shaped connecting ear 42 to have a certain adjustment space during insertion, that is, the S-shaped connecting ear 42 and the C-shaped connecting ear 41 have a certain allowable rotation space in the horizontal direction, especially allowing the distal end of the S-shaped connecting ear 42 to rotate downward relatively appropriately, making the installation more flexible and convenient and also avoiding the breakage of the quick-installation structure 4.

[0047] Such as Figures 3-5As shown in the figure, the air guiding structure 5 includes two mutually parallel linear connecting plates 51. Installation cross bars 52 are distributed along the length direction between the connecting plates 51. An air guiding plate 53 inclined towards one end of the cavity channel 31 is fixed on the installation cross bars 52. The air guiding plates 53 correspond to the ventilation holes 11 one by one, and its upper end is in contact with the bottom surface of the panel 1, and a ventilation gap 54 is formed between its lower end and the substrate 2. A detachable structure is provided between the connecting plates 51 and the support plate 3. The installation cross bar 52 includes an inclined installation surface 55. Installation screw holes are provided on the inclined installation surface 55. The back surface of the air guiding plate 53 is in contact with the inclined installation surface 55. An installation bolt 56 passes through the installation through hole of the air guiding plate 53 and meshes with the installation screw hole for fixation. The front surface of the air guiding plate 53 forms an air guiding surface, and the inclination directions of the air guiding surfaces are the same.

[0048] Specifically, the two linear connecting plates 51 are parallel to each other. Installation cross bars 52 are provided between the connecting plates 51. These cross bars provide fixed points for the installation of the air guiding plates 53. The air guiding plates 53 are fixed on the installation cross bars 52 and inclined towards one end of the cavity channel 31, so that the high-speed air flow blown in from the ventilation holes 11 can smoothly flow towards the end of the cavity channel 31 along the guiding direction of the air guiding plates 53; the air guiding plates 53 are arranged corresponding to the ventilation holes one by one, ensuring that the air flow blown in from each ventilation hole 11 can be effectively guided, reducing the turbulence and eddy current phenomena of the air flow, and reducing noise and vibration; the lower end of the air guiding plate 53 is not in contact with the substrate 2, and a ventilation gap 54 is formed therebetween. This gap allows the air flow guided by each ventilation hole 11 to flow smoothly backward in the same direction, ensuring a smooth guiding ventilation effect; the detachable structure makes the air guiding structure 5 easy to disassemble and replace, and also easy to adjust the angle and position of the air guiding plate 53 according to actual needs to achieve the best ventilation and air guiding effect. The inclined installation surface 55 provides good supporting force for the air guiding plate 53. The air guiding plate 53 and the installation cross bar 52 are firmly and flexibly fixed through the installation bolt 56, which is convenient for disassembly and assembly; all the air guiding plates 53 are inclined towards one end of the cavity channel 31 to guide the air flow to flow smoothly towards the other end.

[0049] As an optimization of this embodiment, the detachable structure includes a card slot 32 provided on the side surface of the support plate 3. The thickness of the connecting plate 51 is adapted to the width of the card slot 32, and the outer side of the connecting plate 51 is clamped in the card slot 32; at least two linear clamping bodies 33 distributed along the length direction and protruding towards the cavity channel 31 are fixed on the side surface of the support plate 3. A card slot 32 is formed between the clamping bodies 33.

[0050] Specifically, the card slot 32 is formed by two straight card bodies 33 protruding inward. Of course, it can also be directly opened on the support plate 3, but the method of forming it by the card body 33 has less impact on the structural strength of the support plate 3, which is a better solution; the outer side of the connecting plate 51 is designed with a structure matching the card slot 32. The connecting plate 51 can be fixed to the support plate 3 through a simple snap-on action, and the disassembly and assembly are flexible and the connection is firm.

[0051] In this embodiment, a positioning structure 6 is provided at the end of the connecting plate 51, and the positioning structure 6 includes a positioning pin hole 61 that penetrates the connecting plate 51, and a positioning pin shaft 62 is inserted into the positioning pin hole 61. The positioning pin shaft 62 is attached to the outer end surface of the support plate 3, the base plate 2 and the panel 1 for limiting position.

[0052] Specifically, the positioning structure 6 is used to position the air guide structure 5 after it is installed to prevent axial movement and ensure that each air guide plate 53 and the vent hole 11 remain corresponding. This is specifically achieved through the positioning pin 62. The positioning pin 62 is inserted into the positioning pin hole 61 and is also limited by the outer end surfaces of the support plate 3, the base plate 2 and the panel 1, having a good axial limiting effect, ensuring the accuracy and stability of the connecting plate 51 during the connection process, and preventing displacement or loosening due to improper installation or external force. In addition, the positioning achieved by the positioning pin 62 is flexible and removable, which is convenient for quick positioning and fixation, helps to improve work efficiency, and reduces installation difficulty and cost.

[0053] As an optimization, a plurality of serrated anti-slip strips 12 are provided on the panel 1, which are distributed along the width direction of the panel 1 and extend along the length direction; the support plates 3 are arranged at an angle, and the inclination directions of adjacent support plates 3 are opposite, and four support plates 3 are provided.

[0054] Specifically, the main purpose of the toothed anti-slip strip 12 is to increase the friction on the surface of the panel 1 to prevent the aircraft or personnel on the apron from slipping when moving, thereby improving safety in use; the support plate 3 is designed to be inclined, and the inclination directions of adjacent support plates 3 are opposite, which helps to disperse the weight and pressure borne by the deck and improve the stability and load-bearing capacity of the structure. At the same time, the number of support plates 3 is an even number, which helps to maintain the overall balance and symmetry of the deck and prevent deflection or deformation during use.

[0055] Specific working principle: During assembly, the quick-install helipad deck is paved on the installed table surface, the S-shaped connecting ear 42 and the C-shaped connecting ear 41 are engaged and fixedly connected, and the base plate 2 and the installed table surface are fixed by a bolt structure, and the installation is completed. When the helicopter takes off and lands, the high-speed airflow generated by its propeller enters the cavity channel 31 from the vent hole 11 of the panel 1, and is guided to one end under the action of the guide plate. When the airflow flows, it blows out the debris, accumulated water and moisture in the cavity channel 31.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
