Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of distribution box, and particularly relates to a distribution box with a self-protection structure. BACKGROUND

[0002] The distribution box is a low-voltage distribution device composed of switchgear, measuring instruments, protective appliances and auxiliary devices assembled in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. The distribution cabinet is generally an open type switch cabinet with a cabinet door. The distribution box can be closed for protection, regular maintenance, etc. by opening the cabinet door. When the distribution box is in use, the electrical components inside the distribution box will generate heat. Most distribution boxes dissipate heat through the heat dissipation grooves arranged on both sides of the distribution box. However, since the heat dissipation grooves are connected to the inside of the distribution box, rainwater can easily enter the distribution box, causing short circuit of the electrical components and safety accidents.

[0003] To this end, the prior art usually provides a heat dissipation structure that can be opened and closed. The heat dissipation structure is inducted to the environmental changes. In rainy days, the heat dissipation holes are closed, and in sunny days, the heat dissipation holes are opened. In this way, the rainwater can be prevented from entering the distribution box in rainy days, and the heat dissipation in the normal use process can also be realized.

[0004] In the prior art, the heat dissipation requirement in rainy and snowy weather is ignored. In rainy and snowy areas, the distribution box is in a closed state, and the heat inside the distribution box cannot be dissipated, which can accelerate the aging of the device circuit. In snowy weather, the snow accumulates on the distribution box, the heat dissipation holes may be in an open state, and the snowmelt enters the distribution box along the cabinet. In addition, the cabinet door shakes back and forth due to wind force in windy and rainy weather, which causes the cabinet door to close loosely, so that the rainwater easily enters the distribution box, which poses a safety risk.

[0068] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0069] As shown in the drawings, the present application provides a power distribution box with a self-protection structure, which has a power distribution box body 1, a heat conduction structure 5, a collection groove seat 6, a liquid cooling heat dissipation structure 7, an air cooling heat dissipation structure 8, an inner self-locking structure 9 and the like. Figures 1-5

[0070] The assembly cavity 3 is the main cavity inside the power distribution box body 1, and the main components required by the power distribution box, such as switch devices, measuring instruments, protective appliances and auxiliary devices, are arranged in the assembly cavity 3. The power distribution box body 1 is an open-close type box body with a box door 12 arranged at the front of the power distribution box body 1. When necessary, the box door 12 is opened to overhaul the devices in the power distribution box body 1.

[0071] A partition plate 2 is installed in the power distribution box body 1, which divides the inside of the power distribution box body 1 into the assembly cavity 3 and the heat dissipation cavity 4 which are not connected in front and back. The assembly cavity 3 is in a fully closed state when the box door 12 of the power distribution box body 1 is closed. When the box door 12 is in a closed state, rainwater cannot enter the assembly cavity 3.

[0072] The heat conduction structure 5 extends from the assembly cavity 3 to the heat dissipation cavity 4 to conduct the heat generated in the assembly cavity 3 to the heat dissipation cavity 4 for heat dissipation.

[0073] The present application mainly uses the liquid cooling heat dissipation structure 7 and the air cooling heat dissipation structure 8 to perform heat dissipation processes under different weather conditions. The liquid cooling heat dissipation structure 7 and the air cooling heat dissipation structure 8 can also be driven to perform heat dissipation. The liquid cooling heat dissipation structure 7 is installed in the heat dissipation cavity 4 and connected to the conduction terminal 11 of the heat conduction structure 5. The liquid cooling heat dissipation structure 7 guides the water collected by the collection groove seat 6 into the heat dissipation cavity 4 to perform liquid cooling heat dissipation on the conduction terminal 11 of the heat conduction structure 5. The air cooling heat dissipation structure 8 is installed in the heat dissipation cavity 4 and connected to the conduction terminal 11 of the heat conduction structure 5. The air cooling heat dissipation structure 8 uses solar energy as a power source to perform air cooling heat dissipation on the conduction terminal 11 of the heat conduction structure 5.

[0074] To assist in completing liquid cooling heat dissipation and protecting the power distribution box body 1 in harsh weather conditions, the present application provides a collection groove seat 6 which is movably installed at the top of the power distribution box body 1 and collects rainwater.

[0075] ​In order to avoid the box door 12 from shaking due to wind force in bad weather, the inner self-locking structure 9 is arranged in the assembly cavity 3, and the inner self-locking structure 9 locks the box door 12 from the inside to limit the opening and closing movement of the box door 12, and the inner self-locking structure 9 fixes the box door 12 in an internally locked manner, wherein the collecting groove seat 6 is pressed downward when collecting rainwater inside, promoting the movement of the inner self-locking structure 9 to internally lock the box door 12, thereby blocking the assembly cavity 3 from the outside environment.

[0076] In the application, the distribution box body 1 is divided into the assembly cavity 3 and the heat dissipation cavity 4 which are not connected in front and back, the gas circulation between the heat dissipation cavity 4 and the outside environment is realized to achieve heat dissipation, the assembly cavity 3 is in a fully closed state when the box door 12 is closed, and the safety of the distribution box body 1 as a whole is improved.

[0077] In addition, in rainy and snowy weather, the liquid cooling heat dissipation mode is adopted to realize the effective utilization of rain and snow water for heat dissipation, in sunny weather, the solar energy is used as a power source, and the air cooling heat dissipation mode is adopted to realize the gas circulation between the heat dissipation cavity 4 and the outside environment for heat dissipation, thereby meeting the heat dissipation requirements of different climate regions.

[0078] In rainy and snowy weather, the rain and snow water is collected in the collecting groove seat 6, on the one hand, the rain and snow water is effectively utilized to provide conditions for liquid cooling, and on the other hand, the inner self-locking structure 9 is internally locked under the driving of the collecting groove seat 6 to make the box door 12 in a stable locked state, thereby avoiding the shaking of the box door 12 and improving the stability and safety of the distribution box body 1.

[0079] The inner self-locking structure 9 is driven by the collecting groove seat 6 to be internally locked, therefore, only in rainy and snowy weather, the rain and snow water is collected in the collecting groove seat 6 to drive the inner self-locking structure 9 to be internally locked, on the one hand, in windy weather (without rain or snow), there is no water entering the inside of the distribution box body 1, therefore, even if the box door 12 is shaken by the wind, the inner self-locking of the box door 12 is not needed, on the other hand, if it is rainy and snowy weather, the rain and snow water slides from the outer wall of the distribution box body 1, and the maintenance personnel need to maintain the distribution box body 1, at this time, the maintenance personnel are easy to bring rainwater into the assembly cavity 3, therefore, in order to ensure safety, the box door 12 has been internally locked at this time, even if the maintenance personnel has opened the outer lock from the outside, the box door 12 cannot be opened, therefore, the inner self-locking of the box door 12 not only can avoid the rainwater from entering due to the shaking of the box door 12 in rainy and windy weather, but also can avoid the rainwater from being brought into the assembly cavity 3 when the maintenance is implemented without maintenance conditions.

[0080] In the application, the collecting groove seat 6 is a structure capable of descending under the action of rain and snow pressure and capable of resetting under the action of no rain and snow pressure. Specifically, the power distribution box body 1 is provided with a movable groove 13, the collecting groove seat 6 is arranged in the movable groove 13, the outer wall of the collecting groove seat 6 is fitted with the inner wall of the movable groove 13, and rain and snow generally cannot penetrate into the movable groove 13 through the gap between the outer wall of the collecting groove seat 6 and the inner wall of the movable groove 13.

[0081] As shown in Figure 4 , the movable groove 13 is provided with an elastic sheet 14, and the bottom of the collecting groove seat 6 is supported on the elastic sheet 14. When the collecting groove seat 6 is not pressed by external force, the elastic sheet 14 lifts the collecting groove seat 6 away from the movable groove 13.

[0082] Under the elastic action of the elastic sheet 14, when there is no rain and snow accumulation on the collecting groove seat 6, the collecting groove seat 6 is lifted to a certain height, and when there is rain and snow accumulation in the collecting groove seat 6, the collecting groove seat 6 is pressed to descend.

[0083] In order to further avoid rain and snow from penetrating into the bottom of the movable groove 13, the movable range of the bottom of the collecting groove seat 6 is limited in the movable groove 13.

[0084] The descent of the collecting groove seat 6 can drive the inner self-locking process of the inner self-locking structure 9 on the box door 12. Specifically, as shown in Figure 6 , Figure 7 and Figure 8 , the inner self-locking structure 9 includes a mounting shaft seat 91 arranged on the inner side wall of the assembly cavity 3, a rotating frame 92 rotatably mounted on the mounting shaft seat 91, and a connecting rod 93 connected to the rotating frame 92.

[0085] The end of the rotating frame 92 is rotatably mounted on the mounting shaft seat 91 through a first rotating shaft 94, the end of the connecting rod 93 is rotatably connected with a rotating seat 97 through a second rotating shaft 95, the back of the box door 12 is provided with a slide rail 98 in the width direction, and the rotating seat 97 is slidably mounted on the slide rail 98.

[0086] As shown in Figure 9 and Figure 10 , the bottom of the collecting groove seat 6 is connected with a clamping bolt 99, the clamping bolt 99 penetrates the power distribution box body 1, and a clamping groove 910 corresponding to the clamping bolt 99 is formed in the first rotating shaft 94.

[0087] When the clamping bolt 99 is clamped into the clamping groove 910 with the collecting groove seat 6 moving downward, the movement of the rotating frame 92 is limited, so as to limit the movement of the box door 12 by pulling the box door 12 through the connecting rod 93.

[0088] If the box door 12 is to be moved outward, the rotating frame 92 will be rotated around the mounting shaft seat 91 by pulling the connecting rod 93, and the inner self-locking structure 9 limits the movement of the box door 12 by limiting the rotation of the rotating frame 92.

[0089] In the initial state, the latch 99 is just opposite to the card slot 910 and does not enter the card slot 910, when the collecting groove base 6 moves under pressure, the latch 99 drops into the card slot 910, when the latch 99 enters the card slot 910, the first rotating shaft 94 cannot rotate, the rotating frame 92 cannot rotate, and the connecting rod 93 cannot move, thereby realizing the restriction on the movement of the box door 12.

[0090] When the rotating frame 92 can rotate freely, the outward rotation of the box door 12 drives the rotating frame 92 to rotate outward, at the same time, the rotating seat 97 slides on the slide rail 98, in order to reduce the resistance of the outward movement of the box door 12, the rotating seat 97 can be provided with a ball outside, the ball rolls in the slide rail 98, so that the friction of the rotating seat 97 moving on the slide rail 98 is greatly reduced, and the box door 12 can be easily opened outward.

[0091] Generally, in rainy and snowy weather, rain and snow accumulate on the collecting groove base 6, which promotes the self-locking structure 9 to lock the box door 12, and the effectiveness of the self-locking structure 9 depends on whether the collecting groove base 6 can smoothly move under pressure, under the condition that the distribution box body 1 is used outdoors for a long time, some sundries may enter the gap between the collecting groove base 6 and the movable groove 13, affecting the movement of the collecting groove base 6, for this, a protective cover 19 can be arranged on the top of the distribution box body 1, above the gap between the collecting groove base 6 and the movable groove 13, to prevent sundries from entering the gap.

[0092] In the present application, the heat generated in the assembly cavity 3 is conducted to the heat dissipation cavity 4 through the heat conduction structure 5, specifically, as shown in the figure, Figure 11 The heat conduction structure 5 includes a heat conduction base 51 and a heat pipe 52 connected to the heat conduction base 51.

[0093] The heat pipe 52 penetrates the partition plate 2, the end of the heat pipe 52 connected to the heat conduction base 51 forms the conduction start end 10 of the heat conduction structure 5, and the end of the heat pipe 52 away from the assembly cavity 3 forms the conduction terminal end 11 of the heat conduction structure 5.

[0094] The heat conduction base 51 is made of heat-conducting material, the heat pipe 52 contains cooling liquid, the cooling liquid is vaporized by heat at the conduction start end 10 and flows to the conduction terminal end 11, and is condensed into liquid after being cooled by liquid cooling or air cooling, and then flows back to the conduction start end 10, the heat pipe 52 contains capillary porous material, and the condensed liquid generally returns to the conduction start end 10 under capillary action.

[0095] In actual application, the heat pipe 52 can be arranged in a ring-shaped pipe structure to ensure the overall heat conduction effect of the heat conduction structure 5, the pipe section of the ring-shaped pipe structure close to the heat conduction base 51 forms the conduction start end 10 of the heat conduction structure 5, and the pipe section close to the liquid cooling structure 7 and the air cooling structure 8 forms the conduction terminal end 11 of the heat conduction structure 5.

[0096] In the present application, the liquid cooling heat dissipation structure 7 guides the water collected by the collecting groove base 6 into the heat dissipation cavity 4 to implement liquid cooling heat dissipation on the conduction terminal 11 of the heat conduction structure 5. Specifically, as shown in Figure 11 、 Figure 12 the liquid cooling heat dissipation structure 7 includes water cooling cabins 71 symmetrically arranged in the heat dissipation cavity 4, a water inlet pipe 72 and a water outlet pipe 73 mounted on the water cooling cabins 71;

[0097] The conduction terminal 11 of the heat pipe 52 penetrates the two water cooling cabins 71 in sequence, the water inlet pipe 72 and the water outlet pipe 73 are in communication with the inside of the water cooling cabins 71, the connection of the water inlet pipe 72 on the water cooling cabin 71 is close to the top of the water cooling cabin 71, and the connection of the water outlet pipe 73 on the water cooling cabin 71 is close to the bottom of the water cooling cabin 71;

[0098] The water inlet pipe 72 is connected to the collecting groove base 6 through a connecting pipe head 74, and the bottom of the water outlet pipe 73 is connected to the water outlet 75 at the bottom of the distribution box body 1.

[0099] After the water is collected in the collecting groove base 6, the water enters the water inlet pipe 72 through the connecting pipe head 74, and then enters the water cooling cabin 71 through the water inlet pipe 72, and then is discharged through the water outlet pipe 73.

[0100] Considering that there are many sundries in the rain and snow water in actual application, if they enter the water cooling cabin 71, long-term accumulation may cause the water to be unable to flow down, resulting in poor water cooling effect. In view of this, the present application is designed as follows: a loading and unloading cabin 15 is arranged in the heat dissipation cavity 4, and the connecting pipe head 74 is arranged in the loading and unloading cabin 15, and a cabin door 16 is movably mounted outside the loading and unloading cabin 15;

[0101] As shown in Figure 12 and Figure 13 the connecting pipe head 74 includes a threaded joint 741 screwed on the end of the water inlet pipe 72, a first sleeve 742 connected to the threaded joint 741, a second sleeve 743 sleeved outside the first sleeve 742, and a third sleeve 744 threadedly sleeved outside the second sleeve 743;

[0102] The first sleeve 742, the second sleeve 743 and the third sleeve 744 are arranged in sequence from bottom to top, and the inner periphery of the top end of each of them is provided with a sundry blocking ring 745, and a filter screen 746 is arranged between the first sleeve 742 and the threaded joint 741;

[0103] The collecting groove base 6 is connected to a connecting pipe 76 at the bottom, the connecting pipe 76 is connected to the third sleeve 744, and when the connecting pipe 76 moves downward along with the collecting groove base 6, the connecting pipe 76 gradually sleeves outside the third sleeve 744.

[0104] In the above embodiment, the connecting pipe head 74 is designed, and the connecting pipe head 74 is composed of the first sleeve 742, the second sleeve 743 and the third sleeve 744 with gradually decreasing inner diameters. When the sundries follow the underwater flow, most of the sundries are blocked and retained by the upper pipe ends of the first sleeve 742, the second sleeve 743 and the third sleeve 744. With the setting of the material blocking ring 745, the sundries are further blocked into the next sleeve layer at each sleeve layer. Under the blocking of the sleeves, most of the sundries are retained in the first sleeve 742, the second sleeve 743 and the third sleeve 744. The sundries that are not blocked are blocked at the filter screen 746. The material blocking ring 745 of each sleeve layer can retain part of the sundries between the sleeve layers, so as to avoid the complete accumulation on the filter screen 746 and cause the blockage. Based on the above process, the sundries in the water are filtered in the connecting pipe head 74, so as to avoid entering the water cooling cabin 71 and causing the blockage.

[0105] Since the collecting groove seat 6 is up and down movable, the connecting pipe 76 is also up and down movable, and the connecting pipe 76 and the third sleeve 744 are movably connected. When the connecting pipe 76 moves downward along with the collecting groove seat 6, the third sleeve 744 is fixed, and the connecting pipe 76 is gradually sleeved outside the third sleeve 744.

[0106] In the above embodiment, the connecting pipe head 74 is detachable. The connecting pipe head 74 is disassembled every certain period of time, the sundries in the connecting pipe head 74 are cleaned, and then the connecting pipe head 74 is installed. The disassembly process is as follows: the cabin door 16 is opened, the threaded joint 741 is rotated, the threaded joint 741 is separated from the water inlet pipe 72, then the threaded joint 741, the first sleeve 742 and the second sleeve 743 are held, the third sleeve 744 is rotated, the connecting pipe head 74 is shortened as a whole, and the connecting pipe head 74 is dismounted from between the water inlet pipe 72 and the connecting pipe 76. The installation process is as follows: the cabin door 16 is opened, the threaded joint 741 is aligned with the water inlet pipe 72, the threaded joint 741 is rotated and assembled on the water inlet pipe 72, the third sleeve 744 is reversely rotated, the connecting pipe head 74 is elongated as a whole, until the third sleeve 744 approaches the connecting pipe 76, and the installation is completed.

[0107] Since the connecting pipe 76 and the third sleeve 744 are movably connected, in the initial state, the connecting pipe 76 is not completely sleeved outside the third sleeve 744, and the water flowing out of the connecting pipe 76 may flow out from the gap between the connecting pipe 76 and the third sleeve 744. In this regard, the present application is designed as follows: the third sleeve 744 is connected with the upwardly open leakage prevention sleeve 747 at the top end. The inner diameter of the leakage prevention sleeve 747 is greater than the outer diameter of the connecting pipe 76. The leakage prevention sleeve 747 can collect a small amount of liquid flowing out from the gap between the connecting pipe 76 and the third sleeve 744, so as to avoid the liquid dripping.

[0108] During the process of water flowing downwards through the inlet pipe 72, the water-cooling chamber 71, and the outlet pipe 73, if there is no obstruction, the water flow may be too fast. On the one hand, the liquid in the collection tank 6 cannot accumulate a certain amount and is pushed down; on the other hand, the rapid downward flow of water prevents the liquid from remaining in the water-cooling chamber 71, resulting in poor water cooling effect. To address this, the present invention makes the following design: Figure 5 As shown, a threaded pipe head 77 is installed downward at the drain outlet 75, and a water leakage pipe head 78 is threaded onto the threaded pipe head 77. A water passage hole is opened on the water leakage pipe head 78.

[0109] The diameter of the water passage hole is generally set to 3~5mm, so that the water in the inlet pipe 72, water cooling chamber 71 and water outlet pipe 73 flows down slowly, and a certain amount of liquid can accumulate in the collection tank 6. It can be pressured down and drive the internal self-locking structure 9 to lock the box door 12. In addition, a certain amount of liquid can be stored in the water cooling chamber 71, which can perform water cooling heat dissipation on the heat pipe 52.

[0110] The liquid cooling structure 7 can dissipate heat in rainy or snowy weather, while the air-cooled structure 8 can dissipate heat in sunny weather. The air-cooled structure 8 uses solar energy as a power source to dissipate heat to the conduction terminal 11 of the heat-conducting structure 5. Specifically, for example... Figure 12 As shown, the air-cooled heat dissipation structure 8 includes a U-shaped guide plate 81 disposed between the water-cooled chambers 71 and a plurality of heat dissipation fins 82 disposed on the U-shaped guide plate 81. The heat dissipation fins 82 are disposed in a direction perpendicular to the heat pipe 52.

[0111] A mounting bracket 83 is installed inside the heat dissipation cavity 4 at the bottom of the loading and unloading compartment 15. A heat dissipation fan 84 is installed on the mounting bracket 83, which is directly opposite the heat dissipation fins 82. An energy storage element that supplies power to the heat dissipation fan 84 is installed inside the heat dissipation cavity 4. A photovoltaic panel is installed outside the power distribution box 1.

[0112] The photovoltaic panel converts solar energy into electrical energy and stores it in the energy storage element. The energy storage element powers the cooling fan 84. When the cooling fan 84 is working, it blows air directly onto the heat sink 82. After the airflow blows onto the heat sink 82, it is guided out from both sides of the U-shaped guide plate 81, realizing gas flow circulation.

[0113] Among them, such as Figure 14 As shown, the length of the U-shaped guide plate 81 is greater than the cross-sectional width of the gas flow area 85 driven by the cooling fan 84, so that the two sides of the U-shaped guide plate 81 are far away from the gas flow area 85. The gas with heat flowing out from the two sides of the U-shaped guide plate 81 can flow out in the opposite direction of the gas entering, avoiding the situation where it cannot flow out under the blowing of the wind.

[0114] If the heat dissipation cavity 4 is in the open state, the rainwater in the heat dissipation cavity 4 will also cause erosion to the pipeline and other structures, and for this, the application is designed as follows, as shown in Figure 5 and Figure 15 The power distribution box body 1 is provided with a ventilation window 86 opposite to the outer wall of the mounting frame 83, and the ventilation window 86 is provided with wind passing grating plates 87 installed at equal intervals from top to bottom.

[0115] The adjacent wind passing grating plates 87 form wind passing gaps 89, and the wind passing grating plates 87 can rotate around the movable shaft 88 to adjust the size and direction of the wind passing gaps 89.

[0116] Each wind passing grating plate 87 is connected with a pull rope 810, the pull rope 810 passes through the loading and unloading cabin 15, and the end thereof away from the wind passing grating plate 87 is connected to the bottom of the collecting groove seat 6, when the collecting groove seat 6 is pressed to move downward, the wind passing grating plate 87 rotates downward under the action of its own gravity to make the wind passing gap 89 smaller and closed, preventing the rainwater from entering the heat dissipation cavity 4.

[0117] In sunny days, the collecting groove seat 6 is lifted to a certain height, the wind passing grating plate 87 is pulled up through the pull rope 810, so that the wind passing grating plate 87 tends to be horizontal, the heat dissipation cavity 4 is connected with the outside, and under the driving of the heat dissipation fan 84, the gas circulation can be realized.

[0118] In rainy days, the collecting groove seat 6 is pressed to move downward, the pull rope 810 is lowered, and the wind passing grating plate 87 rotates downward under the action of its own gravity to make the wind passing gap 89 smaller and closed, at this time, the heat dissipation cavity 4 is basically not connected with the outside, if the energy storage element still has electricity, the heat dissipation fan 84 continues to operate, so that the heat in the heat dissipation cavity 4 is homogenized, avoiding the heat from gathering at the heat dissipation fin 82 and causing no heat dissipation effect, when the electricity is consumed to a certain value or completely consumed, the heat dissipation fan 84 stops operating.

[0119] In the case of needing to urgently repair the structure in the assembly cavity 3, it is generally necessary to release the internal self-locking and open the box door 12, and for this, the application is designed as follows, as shown in Figure 2 The power distribution box body 1 is provided with a side opening 17 opposite to the bottom of the movable groove 13, and the collecting groove seat 6 is provided with an inclined surface 18 opposite to one side bottom edge of the side opening 17.

[0120] A rod-shaped auxiliary part (a straight steel pipe can be used as the rod-shaped auxiliary part) is inserted into the side opening 17 and props up the collecting groove seat 6 along the inclined surface 18, so that the collecting groove seat 6 is lifted to the initial position, at this time, the internal self-locking structure 9 no longer locks the box door 12, and the box door 12 can be smoothly opened from the outside.

[0121] The side opening 17 can also guide the liquid seeping into the gap between the outer wall of the collecting groove 6 and the inner wall of the movable groove 13.

[0122] In summary, the main implementation process of the present application is as follows:

[0123] On sunny days, the collecting groove 6 is lifted to a certain height, and the air-passing grate 87 is pulled up by the pull rope 810, so that the air-passing grate 87 tends to be horizontal, and the heat dissipation cavity 4 is in communication with the outside;

[0124] The heat dissipation fan 84 works, blowing air directly against the heat dissipation fins 82, and the air introduced from the outside is blown against the heat dissipation fins 82 and is guided out from both sides of the U-shaped flow guide plate 81, realizing the circulation of gas flow;

[0125] The cooling liquid is vaporized by heat at the conducting start end 10 and flows to the conducting end 11, and after being cooled and condensed into liquid by air cooling, it flows back to the conducting start end 10;

[0126] In rainy and windy weather, when rain and snow accumulate in the collecting groove 6, the collecting groove 6 is pressed to descend, the catch bolt 99 enters the catch groove 910, the first rotating shaft 94 cannot rotate, the rotating frame 92 cannot rotate, and the connecting rod 93 cannot move, thereby realizing the limitation of the movement of the box door 12, and the box door 12 is locked from the inside;

[0127] At the same time, the collecting groove 6 is pressed to descend, the pull rope 810 is lowered, the air-passing grate 87 is rotated downward under the action of its own gravity, the air-passing gap 89 is reduced and closed, and the heat dissipation cavity 4 is basically not in communication with the outside, so that rainwater cannot enter the heat dissipation cavity 4;

[0128] After the water is collected in the collecting groove 6, the water enters the water inlet pipe 72 through the connecting pipe head 74, and then enters the water cooling cabin 71 through the water inlet pipe 72, and then the water is discharged through the water outlet pipe 73, and the water in the water cooling cabin 71 is retained by controlling the water outlet flow of the water outlet pipe 73.

[0129] The cooling liquid is vaporized by heat at the conducting start end 10 and flows to the conducting end 11, and after being cooled and condensed into liquid by air cooling, it flows back to the conducting start end 10.

[0130] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the present application.
