DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is merely meant to provide a better understanding of the subject matter described herein and can be changed in function and arrangement without departing from the scope of the disclosure. Various processes or components can be omitted, substituted, or added according to desired implementations. Additionally, features described with respect to some examples can be combined in other examples.

[0032] As shown in Figures 1-11 An airport high-pole lamp arcless distribution box includes a distribution box body 1, the distribution box body 1 is provided with a box door 11, and the distribution box body 1 is a prior art. The airport high-pole arcless distribution box 1 further includes an outer shell 2, a first fan 3, and a spray assembly 5. The outer shell 2 mainly plays a role of installation and support. The first fan 3 mainly plays a role of air extraction. The spray assembly 5 mainly plays a role of spraying and evaporating heat to the outer shell 2 to accelerate the dissipation of heat in the outer shell 2.

[0033] Specifically, as shown in Figure 2 and Figure 3 An installation cavity 21 is arranged inside the outer shell 2, the top and bottom of the outer shell 2 are respectively provided with an air outlet 23 and an air inlet 22, and an opening 24 is arranged on a side wall of the outer shell 2. The distribution box body 1 is installed inside the installation cavity 21, so that the distribution box body 1 is protected by the outer shell 2. In addition, the box door 11 of the distribution box body 1 is adaptively installed with the opening 24, that is, the position of the box door 11 is installed at the position of the opening 24, so that the opening and closing operation of the box door 11 by the operator is facilitated. Since hot air moves upward, it is more reasonable to arrange the air inlet 22 at the bottom of the outer shell 2 and the air outlet 23 at the top of the outer shell 2, so as to facilitate the discharge of hot air in the installation cavity 21.

[0034] The first fan 3 is fixedly installed in the installation cavity 21, and is used to introduce external air into the installation cavity 21 through the air inlet 22, and then discharge the heat in the installation cavity 21 from the air outlet 23 at the top of the outer shell 2. It should be noted that the bottom of the outer shell 2 is provided with a plurality of second support columns 102, so that a gap is left between the air inlet 22 and the ground, facilitating the entry of external air into the installation cavity 21.

[0035] As an optional embodiment, as shown in Figure 3 The bottom of the distribution box body 1 is fixedly connected with a plurality of first support columns 101, which can leave a gap between the bottom of the distribution box body 1 and the bottom of the installation cavity 21, thereby reducing the contact area between the distribution box body 1 and the outer shell 2, and facilitating heat dissipation of the distribution box body 1.

[0036] In addition, as shown in Figure 4 and Figure 5 The spray assembly 5 comprises a water collecting tank 51, a cylindrical fixing seat 52, a horn-shaped and elastic vibration plate 53, and a trigger assembly 54. The water collecting tank 51 is mainly used for water storage and drainage, and a water inlet is formed at the top of the water collecting tank 51. A first flow channel 25 is formed at the top of the outer shell 2, and the first flow channel 25 can be vertically arranged. The water collecting tank 51 is fixedly connected to the outer top of the outer shell 2 and communicates with one end of the first flow channel 25, that is, the water in the water collecting tank 51 can flow into the first flow channel 25. The vibration plate 53 can be made of aluminum alloy or other suitable materials.

[0037] The fixing seat 52 is fixedly connected to the inner top of the outer shell 2, and a second flow channel 521 is formed in the fixing seat 52 and communicates with the other end of the first flow channel 25. The second flow channel 521 can also be vertically arranged, that is, the water flowing into the first flow channel 25 from the water collecting tank 51 can further flow into the second flow channel 521. The vibration plate 53 is arranged below the fixing seat 52. Since the vibration plate 53 is a horn-shaped structure with the opening 24 facing upward, the water flowing into the second flow channel 521 can further flow onto the vibration plate 53. A plurality of spray holes 531 are formed in the vibration plate 53, and the trigger assembly 54 is used to repeatedly press the vibration plate 53 along the vertical direction towards the fixing seat 52, so as to spray the water flowing into the vibration plate 53 from the water collecting tank 51 from the spray holes 531 into the installation cavity 21.

[0038] In use, when the trigger assembly 54 lifts the vibrating plate 53 upward, the vibrating plate 53 will press against the bottom of the fixed seat 52, and in the process, the water on the vibrating plate 53 will be sprayed out of the spray holes 531 in the form of mist into the installation cavity 21 under the pressure, the sprayed mist will evaporate by absorbing heat and be discharged from the air outlet 23, thereby accelerating the heat dissipation speed in the installation cavity 21, and further facilitating the heat dissipation of the distribution box body 1. When the trigger assembly 54 lowers the vibrating plate 53, the vibrating plate 53 returns to its original state and is in a water storage state, so as to press and spray again, thereby realizing the effect of reciprocating spraying. It should be noted that the caliber of the spray holes 531 can be set according to the actual working conditions. In addition, water mist is easier to evaporate than liquid water, which is conducive to heat dissipation.

[0039] Further, as shown in Figure 3 , the trigger assembly 54 includes a trigger rod 541, a guide seat 542, and a pneumatic cylinder 543. The pneumatic cylinder 543 is fixedly connected to the bottom of the installation cavity 21, the trigger rod 541 is vertically arranged, one end of the trigger rod 541 is fixedly connected to the bottom of the vibrating plate 53, the other end is fixedly connected to the telescopic end of the pneumatic cylinder 543, and the guide seat 542 is fixedly connected in the installation cavity 21 and slidably connected with the trigger rod 541. In use, the pneumatic cylinder 543 drives the trigger rod 541 to move in the vertical direction, thereby controlling the repeated pressing of the vibrating plate 53 and the fixed seat 52. The guide seat 542 mainly plays a guiding and supporting role, and the guide seat 542 is slidably connected with the trigger rod 541, so that the movement of the trigger rod 541 is more stable, thereby making the pressing cooperation between the vibrating plate 53 and the fixed seat 52 more stable.

[0040] In addition, as shown in Figure 4 and Figure 5 , the vibrating plate 53 is arranged with the larger caliber side edge abutting against the bottom of the fixed seat 52. That is, in the initial state, the vibrating plate 53 is arranged with the larger caliber side edge abutting against the bottom of the fixed seat 52, so that a relatively sealed chamber is formed between the vibrating plate 53 and the fixed seat 52 except for the spray holes 531, which can reduce the water leakage from the gap between the vibrating plate 53 and the fixed seat 52, thereby better spraying the water on the vibrating plate 53 from the spray holes 531 and improving the spraying effect.

[0041] In addition, as shown in Figure 5 , the plurality of spray holes 531 are arranged close to the larger caliber side edge of the vibrating plate 53. Since the water in the water collecting tank 51 flows into the vibrating plate 53 through the first flow channel 25 and the second flow channel 521, it will first accumulate away from the larger caliber side edge of the vibrating plate 53. Therefore, the plurality of spray holes 531 are arranged close to the larger caliber side edge of the vibrating plate 53, so that when the trigger assembly 54 does not trigger the vibrating plate 53, that is, when the vibrating plate 53 is in a water storage state, the water leakage from the spray holes 531 is reduced.

[0042] Further, as shown in Figure 5 , the bottom edge of the fixed seat 52 is provided with a ring-shaped limiting plate 522 to limit the edge of the larger caliber side of the vibration plate 53. That is, the limiting plate 522 mainly plays a limiting role, and when the vibration plate 53 extrudes the fixed seat 52, the limiting plate 522 can limit the edge of the larger caliber side of the vibration plate 53, so that the vibration plate 53 can maintain a relatively stable shape. Moreover, it can also reduce the water flow from the gap between the vibration plate 53 and the fixed seat 52 to a certain extent.

[0043] In addition, as shown in Figure 5 , the caliber of the first flow channel 25 is smaller than the caliber of the second flow channel 521, and the vibration plate 53 is fixedly connected with a sealing rod 103, which can be vertically arranged. The sealing rod 103 selectively seals with the first flow channel 25 through the second flow channel 521. Specifically, when the trigger assembly 54 drives the vibration plate 53 to extrude the bottom of the fixed seat 52 upward, the sealing rod 103 will move upward to seal the first flow channel 25 at this time, so as to prevent the water in the water collecting tank 51 from continuing to flow to the vibration plate 53. When the trigger assembly 54 drives the vibration plate 53 to move downward, the sealing rod 103 is separated from the first flow channel 25, and the water in the water collecting tank 51 can flow into the vibration plate 53 through the first flow channel 25 and the second flow channel 521. In this way, the inflow of water in the water collecting tank 51 to the vibration plate 53 can be flexibly controlled, thereby reducing water loss without the need for heat dissipation.

[0044] As an optional embodiment, as shown in Figure 3 , the spray assembly 5 is provided with at least two groups, and is arranged on both sides of the distribution box body 1 respectively. By arranging multiple groups of spray assemblies 5, the heat in the installation cavity 21 can be discharged faster, thereby facilitating heat dissipation of the distribution box body 1. In addition, multiple spray assemblies 5 are arranged on both sides of the distribution box body 1 respectively, so that the heat in the installation cavity 21 can be discharged more comprehensively and uniformly.

[0045] In addition, as shown in Figure 6 , Figures 8-11As shown, in the vertical direction, the cross-sectional shape of the air inlet 22 can be circular. The upper side of the air inlet 22 is provided with an arc-shaped mounting plate 6, which is fixedly connected with the outer shell 2, and the air inlet 22 is provided with a filter plate 7 having a plurality of filter holes formed therein, which is mainly used to prevent large-sized objects from entering the mounting cavity 21. The filter plate 7 is rotatably connected to the side of the mounting plate 6 close to the ground, and the outer bottom of the outer shell 2 is fixedly connected with a brush 8 having bristles, which is specifically fixedly connected to the side close to the mounting plate 6. The length direction of the brush 8 is arranged along the radial direction of the air inlet 22, and in the vertical direction, the projection of the brush 8 on the ground is contained in the projection of the mounting plate 6 on the ground. The airport high-pole lamp arcless distribution box 1 further comprises a driving mechanism 9 for driving the filter plate 7 to rotate so that the brush 8 can clean different positions of the filter plate 7.

[0046] That is, a part of the top of the filter plate 7 is blocked by the mounting plate 6, and when the first fan 3 starts to work, the external air can only enter the mounting cavity 21 through the part not blocked by the mounting plate 6. In use, the filter plate 7 is driven to rotate by the driving mechanism 9, and during the rotation of the filter plate 7, the external air can always enter the mounting cavity 21 through the part of the filter plate 7 not blocked by the mounting plate 6, while the part blocked by the mounting plate 6 is cleaned by the brush 8 during the rotation, so that the filter plate 7 can be cleaned without being removed, thereby prolonging the working time of the filter plate 7. It should be noted that the brush 8 is arranged close to the mounting plate 6, and in the vertical direction, the projection of the brush 8 on the ground is contained in the projection of the mounting plate 6 on the ground, so that the brush 8 cannot clean the part of the filter plate 7 not blocked by the mounting plate 6, thereby reducing the impurities entering the mounting cavity 21 from the filter holes after cleaning.

[0047] Specifically, the driving mechanism 9 comprises a gear ring 91, a gear 92, a rotating shaft 93, a first bevel gear 94, a second bevel gear 95 and a motor 96. The gear ring 91 is fixedly connected to the outer peripheral wall of the filter plate 7, the rotating shaft 93 is arranged through the bottom of the outer shell 2 and is rotatably connected with the outer shell 2, one end of the rotating shaft 93 close to the ground is fixedly connected with the gear 92, and the gear 92 is adapted with the gear ring 91. The other end of the rotating shaft 93 is fixedly connected with the first bevel gear 94, the motor 96 is fixedly connected inside the mounting cavity 21, and the output end of the motor 96 is fixedly connected with the second bevel gear 95, and the second bevel gear 95 is engaged with the first bevel gear 94.

[0048] In use, the motor 96 is started, the motor 96 drives the second bevel gear 95 to rotate, the rotation of the second bevel gear 95 drives the rotating shaft 93 to rotate through the meshing between the first bevel gear 94 and the second bevel gear 95, the rotation of the rotating shaft 93 drives the gear 92 to rotate, the rotation of the gear 92 drives the filter plate 7 to rotate through the cooperation with the gear ring 91.

[0049] As an optional embodiment, as shown in Figure 3 The second fan 4 is fixedly installed at the air outlet 23, and the second fan 4 is used for discharging air in the mounting cavity 21. The installation of the second fan 4 can accelerate the flow of air in the mounting cavity 21, and then can accelerate the discharge of heat in the mounting cavity 21, so as to facilitate the heat dissipation of the distribution box body 1.

[0050] As an optional embodiment, as shown in Figure 1 The ventilation holes 100 are arranged on the opposite two side walls of the outer shell 2. The ventilation holes 100 mainly play a role of ventilation, and the ventilation holes 100 are arranged on the opposite two side walls of the outer shell 2, so that the flow of air in the mounting cavity 21 can be accelerated, and then the discharge of heat in the mounting cavity 21 can be accelerated, so as to facilitate the heat dissipation of the distribution box body 1.

[0051] As an optional embodiment, as shown in Figure 3 The top of the water collecting tank 51 is in a reverse conical structure, and the water inlet is arranged at the middle position of the water collecting tank 51. The one-way valve is fixedly installed at the water inlet, and the flow direction of the one-way valve is to flow into the water collecting tank 51. The reverse conical structure of the water collecting tank 51 can facilitate the collection of rainwater when it rains. The design of the one-way valve can reduce the evaporation of water in the water collecting tank 51.
