DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1 to Figure 2As shown, an overheating protection distribution cabinet described in an embodiment of the present invention includes a distribution cabinet 1; a plurality of protective covers 2 are fixedly connected to the side walls of the distribution cabinet 1; a driving motor 3 is fixedly connected to the interior of the protective cover 2; an adjusting screw 4 is fixedly connected to the output end of the driving motor 3; a support plate 5 for placing the distribution cabinet 1 is provided at the bottom of the distribution cabinet 1; the adjusting screw 4 is threadedly connected at the internal position of the support plate 5; a plurality of support rods 6 are fixedly connected to the bottom of the support plate 5, and the support rods 6 are arranged at positions corresponding to the corners of the adjusting screw 4; a placement base plate 7 is fixedly connected to the bottom end of the support rod 6; a water level sensor is installed at the bottom of the support plate 5, and the water level sensor is located at the center of the bottom of the support plate 5; a cooling component is provided inside the distribution cabinet 1, and the cooling component can cool the heat inside the distribution cabinet 1; when working, when the distribution cabinet 1 is installed in the field, by arranging the support plate 5 and the support rod 6 at the bottom of the distribution cabinet 1 The distribution cabinet 1 is supported by the bottom plate 7, and the distribution cabinet 1 is placed above the support plate 5, so that the distribution cabinet 1 can be raised. At the same time, a water level sensor is set at the bottom of the distribution cabinet 1 to monitor the water level at the bottom of the distribution cabinet 1. When the rainfall is too heavy and the water level at the bottom of the distribution cabinet 1 rises, the water level sensor controls the drive motor 3 to rotate through the PLC, so that the drive motor 3 drives the adjusting screw 4 to rotate, and then drives the distribution cabinet 1 to rise through the threaded cooperation of the adjusting screw 4 and the support plate 5, thereby effectively avoiding the situation where the water level is higher than the bottom of the distribution cabinet 1 and enters the interior of the distribution cabinet 1 to cause damage to the electrical components inside the distribution cabinet 1. If the collection tank 11 is full of water, the position of the support plate 5 is the highest, and the water inside the collection tank 11 can be used for cooling the cooling components. As the water inside the collection tank 11 evaporates, the drive motor 3 controls the support plate 5 to descend until the water inside the collection tank 11 is completely evaporated.

[0031] like Figures 2 to 3 As shown, the cooling assembly includes a water guide 8; the water guide 8 is fixedly connected to the top position of the distribution cabinet 1; a water pipe 9 is opened inside the distribution cabinet 1; a water outlet pipe 10 is fixedly connected to the bottom of the water pipe 9; the outlet pipe 10 is connected to the water pipe 9; the outlet pipe 10 is slidably connected to the inner position of the support plate 5; during operation, when the distribution cabinet 1 is placed in the wild, rainwater from the outside will enter the inside of the water pipe 9 through the water guide 8. When the water passes through the water pipe 9, the water pipe 9 will absorb the heat generated inside the distribution cabinet 1, thereby cooling the heat inside the distribution cabinet 1. After that, the water inside the water pipe 9 will enter the bottom of the support plate 5 through the outlet pipe 10 to discharge the water. At the same time, when the height of the distribution cabinet 1 is adjusted, the sliding of the outlet pipe 10 is restricted by the support plate 5, so that the distribution cabinet 1 can be more stable when sliding.

[0032] like Figures 1 to 4 As shown, a collecting tank 11 is fixedly connected to the top of the placement bottom plate 7; a circulating water pump 12 is fixedly connected to the side wall of the power distribution cabinet 1; the input end and the output end of the circulating water pump 12 are both connected to a water pipe 13, and the bottom end of the water pipe 13 connected to the input end of the circulating water pump 12 is fixedly connected to a counterweight ball 14, and the water pipe 13 connected to the output end of the circulating water pump 12 is guided to the top position of the water guide bucket 8; a support frame 15 is fixedly connected to the top of the power distribution cabinet 1; the water pipe 13 is arranged at an internal position of the support frame 15; the counterweight ball 14 is arranged at a position corresponding to the inner side wall of the bottom of the collecting tank 11; during operation, when the power distribution cabinet 1 is placed in the wild and it is in rainy weather, Rainwater from the outside will enter the interior of the collecting trough 11, so that the rainwater can be collected by the collecting trough 11. When it is rainless, the circulating water pump 12 can be started, and the rainwater in the collecting trough 11 can be transported to the position corresponding to the top of the distribution cabinet 1 through the water pipe 13. After that, the rainwater enters the interior of the water pipe 9 to absorb and cool the heat inside the distribution cabinet 1, thereby continuously achieving the cooling effect of the distribution cabinet 1 and effectively avoiding overheating inside the distribution cabinet 1. By arranging a counterweight ball 14 at the bottom end of the water pipe 13, the bottom end of the water pipe 13 can always stay in the internal position of the collecting trough 11, so that the effect of extracting water can be better.

[0033] like Figures 1 to 3 As shown, a first material retaining net 16 is fixedly connected to the interior of the water guide bucket 8; the first material retaining net 16 is arranged at the bottom of the end of the water guide pipe 13 connected to the output end of the circulating water pump 12; a second material retaining net 17 is fixedly connected to the interior of the collecting tank 11; the second material retaining net 17 is arranged at a position corresponding to the top of the counterweight ball 14; during operation, when the circulating water pump 12 transports rainwater, the impurities in the rainwater are blocked and filtered by arranging the second material retaining net 17 inside the collecting tank 11 and the first material retaining net 16 inside the water guide bucket 8, so that the rainwater entering the interior of the circulating water pump 12 can be made cleaner, thereby effectively preventing impurities from entering the interior of the circulating water pump 12 and affecting the transportation of the circulating water pump 12.

[0034] like Figure 5As shown, the interior of the collecting trough 11 is slidably connected with a sliding plate 18; a plurality of fixed cones 19 are fixedly connected to the bottom of the sliding plate 18; the fixed cones 19 are slidably connected at the internal position of the placement base plate 7; a plurality of springs are fixedly connected between the bottom of the sliding plate 18 and the top of the placement base plate 7; during operation, when the distribution cabinet 1 is placed on the foundation, when rainwater is collected through the collecting trough 11, the rainwater will press the sliding plate 18, thereby pressing the fixed cone 19 down, so that the fixed cone 19 pushes the foundation, which can make the pressure between the bottom of the collecting trough 11 and the foundation greater, and the friction between the bottom of the collecting trough 11 and the foundation greater, so that the placement base plate 7 can be placed on the ground. More stable.

[0035] like Figures 5 and 6 As shown, a plurality of guide blocks 20 are fixedly connected to the side wall of the fixed cone 19; the guide blocks 20 are slidably connected at the internal position of the placement base plate 7; during operation, when the fixed cone 19 slides inside the placement base plate 7, the sliding of the guide blocks 20 is restricted by the placement base plate 7, so that the sliding of the fixed cone 19 can be made more stable, and the fixed cone 19 can remain perpendicular to the ground when inserted into the soil, so that the insertion of the fixed cone 19 is more accurate, and the fixing effect of the placement base plate 7 is better.

[0036] like Figure 5 As shown, a sealing gasket 21 is fixed to the bottom of the sliding plate 18; the side wall of the sealing gasket 21 is in contact with the inner wall of the collecting tank 11; during operation, when rainwater presses the sliding plate 18, by arranging the sealing gasket 21 at the bottom of the sliding plate 18, the sealing between the sliding plate 18 and the inner wall of the collecting tank 11 can be made stronger, thereby effectively preventing rainwater from entering the bottom of the sliding plate 18.

[0037] like Figure 5 As shown, a blocking bar 22 is fixedly connected to the inner wall of the collecting trough 11; the blocking bar 22 is arranged at a position corresponding to the top of the sliding plate 18; when working, when the sliding plate 18 slides inside the collecting trough 11, the blocking bar 22 is arranged to block the sliding plate 18, which can effectively prevent the sliding plate 18 from being higher than the side wall of the collecting trough 11, causing rainwater to enter the bottom of the sliding plate 18.

[0038] like Figure 7 As shown, a positioning block 23 is fixedly connected to the side wall of the adjusting screw 4; the positioning block 23 is rotatably connected to the internal position of the power distribution cabinet 1; during operation, when the adjusting screw 4 rotates inside the power distribution cabinet 1, the rotation of the adjusting screw 4 is limited by the positioning block 23, so that the adjusting screw 4 is less likely to tilt during rotation, making the rotation of the adjusting screw 4 more stable.

[0039] like Figure 7 As shown, a plurality of anti-wear balls 24 are provided between the adjusting screw 4 and the positioning block 23; the side walls of the anti-wear balls 24 are in contact with the side walls of the adjusting screw 4 and the positioning block 23; during operation, when the positioning block 23 rotates inside the distribution cabinet 1, by providing the anti-wear balls 24 between the protective cover 2 and the positioning block 23, the sliding friction between the protective cover 2 and the positioning block 23 can be converted into rolling friction, so that the friction between the protective cover 2 and the positioning block 23 is smaller, thereby reducing the wear between the protective cover 2 and the positioning block 23.

[0040] During operation, when the distribution cabinet 1 is installed in the field, the distribution cabinet 1 is supported by arranging a support plate 5, a support rod 6 and a bottom plate 7 at the bottom of the distribution cabinet 1, so that the distribution cabinet 1 can be raised. At the same time, a water level sensor is arranged at the bottom of the distribution cabinet 1 to monitor the water level at the bottom of the distribution cabinet 1. When the rainfall is too heavy and the water level at the bottom of the distribution cabinet 1 rises, the water level sensor controls the drive motor 3 to rotate through the PLC, so that the drive motor 3 drives the adjusting screw 4 to rotate, and then drives the distribution cabinet 1 to rise through the threaded cooperation of the adjusting screw 4 and the support plate 5, thereby effectively avoiding the situation that the water level is higher than the bottom of the distribution cabinet 1 and enters the interior of the distribution cabinet 1 to cause damage to the electrical components inside the distribution cabinet 1. If the collection tank 11 is full of water, the position of the support plate 5 is the highest, and the water inside the collection tank 11 can be used for cooling the cooling components. As the water inside the collection tank 11 evaporates, the drive motor 3 controls the support plate 5 to descend until the water inside the collection tank 11 is completely evaporated.

[0041] When the distribution cabinet 1 is placed outdoors, rainwater from the outside will enter the inside of the water pipe 9 through the water guide 8. When the water passes through the water pipe 9, the water pipe 9 will absorb the heat generated inside the distribution cabinet 1, thereby cooling the heat inside the distribution cabinet 1. After that, the water inside the water pipe 9 will enter the bottom of the support plate 5 through the outlet pipe 10 and be discharged. At the same time, when the height of the distribution cabinet 1 is adjusted, the sliding of the outlet pipe 10 is restricted by the support plate 5, so that the distribution cabinet 1 can be more stable when sliding.

[0042] When the power distribution cabinet 1 is placed outdoors in rainy weather, rainwater from the outside will enter the collecting tank 11, so that the rainwater can be collected by the collecting tank 11. When it is rainless, the circulating water pump 12 can be started, and the rainwater in the collecting tank 11 can be transported to the position corresponding to the top of the power distribution cabinet 1 through the water pipe 13. After that, the rainwater enters the water pipe 9 to absorb and cool the heat inside the power distribution cabinet 1, thereby continuously achieving the cooling effect of the power distribution cabinet 1 and effectively avoiding overheating inside the power distribution cabinet 1. By arranging a counterweight ball 14 at the bottom end of the water pipe 13, the bottom end of the water pipe 13 can always stay in the internal position of the collecting tank 11, so that the effect of extracting water can be better.

[0043] When the circulating water pump 12 transports rainwater, a second retaining net 17 is arranged inside the collecting tank 11, and a first retaining net 16 is arranged inside the water guide bucket 8 to block and filter impurities in the rainwater. This can make the rainwater entering the circulating water pump 12 cleaner, thereby effectively preventing impurities from entering the circulating water pump 12 and affecting the transportation of the circulating water pump 12.

[0044] When the distribution cabinet 1 is placed on the foundation, when rainwater is collected through the collecting trough 11, the rainwater will press the sliding plate 18, thereby pressing down the fixed cone 19, so that the fixed cone 19 pushes the foundation, which can make the pressure between the bottom of the collecting trough 11 and the foundation greater, and the friction between the bottom of the collecting trough 11 and the foundation greater, so that the base plate 7 can be placed more stable when placed on the ground.

[0045] When the fixing cone 19 slides inside the placement base plate 7, the placement base plate 7 restricts the sliding of the guide block 20, which can make the sliding of the fixing cone 19 more stable, so that the fixing cone 19 remains perpendicular to the ground when inserted into the soil, and the insertion of the fixing cone 19 is more accurate, which has a better fixing effect on the placement base plate 7.

[0046] When rainwater presses the sliding plate 18, by providing a sealing gasket 21 at the bottom of the sliding plate 18, the sealing between the sliding plate 18 and the inner wall of the collecting tank 11 can be made stronger, thereby effectively preventing rainwater from entering the bottom of the sliding plate 18.

[0047] When the sliding plate 18 slides inside the collecting trough 11 , the blocking strip 22 is provided to block the sliding plate 18 , which can effectively prevent the sliding plate 18 from being higher than the side wall of the collecting trough 11 , causing rainwater to enter the bottom of the sliding plate 18 .

[0048] When the adjusting screw 4 rotates inside the protective cover 2, the rotation of the adjusting screw 4 is limited by the positioning block 23, so that the adjusting screw 4 is less likely to tilt during rotation, and the rotation of the adjusting screw 4 is more stable;

[0049] When the positioning block 23 rotates inside the distribution cabinet 1, by arranging anti-wear balls 24 between the protective cover 2 and the positioning block 23, the sliding friction between the protective cover 2 and the positioning block 23 can be converted into rolling friction, so that the friction force between the protective cover 2 and the positioning block 23 is smaller, thereby reducing the wear between the protective cover 2 and the positioning block 23.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
