Example (b):
as shown in fig. 1 to 4, the invention provides an electric cabinet on water, which comprises a cabinet body 1, a floating seat 2 and a heat dissipation mechanism. The cabinet body 1 is connected to the upper part of the floating seat 2. The floating seat 2 supports the cabinet body 1, so that the cabinet body 1 floats on the water surface. The heat dissipation mechanism comprises a circulating pump 3 and a plurality of circulating pipelines. The inside of the circulating pump 3 and the cabinet body 1 are communicated with the circulating pipeline, so that the circulating pump 3, the cabinet body 1 and the circulating pipelines enclose a circulating passage. Part of the circulation line extends below the pontoon 2, so that this part is submerged in the water. The cabinet 1 is also provided with a sealing door 11.
When the overwater electric cabinet is used, the cabinet body 1 floats on the water surface through the floating seat 2. When the water level rises or falls, the floating seat 2 rises and falls, and the cabinet body 1 is effectively prevented from being flooded. In use, the cabinet body 1 is sealed under the action of the sealing door 11. External moist air is prevented from entering the cabinet 1. Meanwhile, the air inside the cabinet 1 circulates along the circulation path by the circulation pump 3. The air contacts with the electrical components in the cabinet 1, and further takes away heat of the electrical components. Subsequently, the heated air is extended to a portion below the floating seat 2 through the circulation line. This allows the heated air to be cooled down because this area is flooded with water. And cooling the electrical elements by the cooled air. This just is fine dispels the heat to the inside of electrical cabinet.
The overwater electric appliance cabinet has a good heat dissipation effect, and meanwhile, the cabinet body 1 is prevented from being placed in a humid environment for a long time to damage electric appliance elements in the cabinet. In addition, the external air cannot enter the cabinet body 1, and dust is prevented from entering the cabinet body 1.
In this embodiment, the floating seat 2 is provided in a ring shape. The upper part of the floating seat 2 is provided with a mounting plate 5. The cabinet body 1 is fixedly arranged on the mounting plate 5. The floating seat 2 is generally made of material-conveying foam and the like. It is softer in texture. The strength is enhanced through the mounting plate 5, and the cabinet body 1 is further mounted more stably. Meanwhile, the cabinet body 1 and the floating seat 2 are also separated by the mounting plate 5, so that the damp-proof effect is achieved. The mounting plate 5 may also be provided with guide holes. After the guide rod 51 is inserted into the water bottom, the guide hole is fitted to the outside of the guide rod 51. Thereby enabling the mounting plate 5 to be lifted and lowered along the guide rods 51. The guide rod 51 can prevent the electrical cabinet from drifting away. The inner wall of the floating seat 2 is provided with an elastic air bag 6. The air bag 6 is inflated, expanded and deflated. The air bag 6 is respectively connected with an air outlet and an air inlet of the circulating pump 3 through pipelines. A first valve 61 is arranged between the air bag 6 and the air outlet of the circulating pump 3. A fourth valve 62 is arranged between the air bag 6 and the air inlet of the circulation pump 3. A second valve 71 is also arranged between the air outlet of the circulating pump 3 and the cabinet body 1. The second valve 71 is arranged in parallel with the first valve 61.
In summer, the cabinet body 1 may be exposed to the sun, thereby making the temperature inside the cabinet body 1 higher. At this time, the first valve 61 is closed and the fourth valve 62 is opened. The circulation pump 3 draws out and discharges the air inside the air bag 6 to the inside of the cabinet 1. This causes the air bag 6 to deflate, thereby causing the floating seat 2 to sink. Thereby causing more of the circulation lines to be submerged in the water. The cooling effect of air is better, and the radiating effect of the cabinet body 1 is better. Meanwhile, the air in the cabinet body 1 is increased, the density is increased, and the heat dissipation is facilitated. In a similar way, when higher heat dissipation efficiency is not needed, the air bag 6 can be inflated, so that the floating seat 2 floats upwards, and a circulating pipeline entering water is reduced. The annular float seat 2 also protects the airbag 6 therein.
In this embodiment, the circulation line comprises a helical coil 7. The coil pipe 7 is arranged inside the floating seat 2 and vertically extends to the lower part of the floating seat 2. One end of the coil 7 is connected with the air outlet of the circulating pump 3. The end of the coil 7 connected to the circulation pump 3 is provided with a second valve 71. The second valve 71 is arranged in parallel with the first valve 61. The coil 7 allows a longer path for the air to travel, which in turn allows the air to better exchange heat with the water. Further guarantee the radiating effect.
In this embodiment, the bottom of the floating seat 2 is covered with a mesh plate 8. The air bag 6 and the coil pipe 7 are both arranged between the mesh plate 8 and the floating seat 2. The net plate 8 wraps the air bag 6 and the coil pipe 7, so that the air bag 6 and the coil pipe 7 are prevented from being contacted by aquatic weeds or sundries in water. Thereby better protecting the air bag 6 and the coil 7. The net plate 8 is arranged by protruding from the bottom of the floating seat 2. The net plate 8 is arranged in a spherical shape. When the waves surge to the screen plate 8, water can be dispersed to both sides under the guide of the screen plate 8, and then the impact force of the surge on the electrical cabinet is reduced.
In this embodiment, the bottom of the mounting plate 5 is provided with a connecting rod 91. The connecting bar 91 passes through the floating seat 2 and the mesh plate 8 and extends downward of the floating seat 2. One end of the connecting rod 91, which is far away from the mounting plate 5, is provided with a balancing weight 9. The balancing weight 9 is tensioned downwards, so that the electrical cabinet is prevented from being tipped over, and the stability of the electrical cabinet is stronger. In practice, the coil 7 is coiled outside the tie-bar 91. Thereby providing good support for the coil 7.
In this embodiment, the circulation line includes a casing tube 10. The cabinet wall pipe 10 is bent into a plate shape inside the cabinet wall of the cabinet body 1, so that the cabinet wall pipe 10 is uniformly distributed inside the cabinet wall of the cabinet body 1. One end of the cabinet wall pipe 10 is connected to the inside of the cabinet body 1, and the other end is connected to the air inlet of the circulating pump 3. The third valve 101 is provided at the end of the casing tube 10 connected to the inside of the cabinet 1. When the air temperature is low, the fourth valve 62, the second valve 71 and the third valve 101 are all closed, the first valve 61 is opened, and the circulating pump 3 pumps the air in the cabinet wall pipe 10 to the inside of the air bag 6. Thereby reducing the air density in the cabinet wall tube 10 and reducing the heat exchange between the inside and outside of the cabinet 1. Thereby avoiding the influence of the low temperature in the cabinet body 1 on the normal work of the electric elements.
In this embodiment, the drying box 4 is further disposed at one end of the cabinet wall tube 10 connected to the inside of the cabinet 1. A drying agent is arranged in the drying box 4. In actual use, the cabinet door can be opened and closed. This allows moist air to enter the cabinet 1. The incoming moist air is dried by the desiccant in the drying box 4.
In this embodiment, the cabinet 1 is provided with an air inlet end 12 and an air outlet end 13. The air inlet end 12 is disposed at the center of the bottom of the cabinet 1. The air outlet end 13 is arranged at the center of the top of the cabinet 1. The cabinet 1 is also provided with an air deflector 14. The air deflector 14 is funnel shaped. The lowest point of the air deflector 14 is located directly above the air inlet end 12. A plurality of air holes 15 are uniformly distributed on the air deflector 14. The two ends of the circulating pipeline connecting cabinet body 1 are respectively connected with an air inlet end 12 and an air outlet end 13.
When in use, cooled air enters the cabinet body 1 from the air inlet end 12 at the bottom of the cabinet body 1 and gradually fills the cabinet body 1. The air after the temperature rise is exhausted through the air outlet end 13 at the top of the cabinet body 1. This allows the cold air to be better filled in the cabinet 1 since the cold air sinks. The cool air introduced through the inlet end 12 is guided to the respective locations by the air guide plate 14 and rises through the respective air holes 15. This allows a better and uniform distribution of the cold air inside the cabinet 1. Better heat dissipation.
A control method of an electric cabinet is used for controlling the above-water electric cabinet. The waterborne electrical cabinet also comprises a temperature sensor and a control unit. The temperature sensor, the fourth valve 62, the second valve 71, the third valve 101 and the first valve 61 are all connected to the control unit. The temperature sensor is used for monitoring the temperature inside the cabinet 1.
The electrical cabinet control method comprises the following steps: when the temperature sensor detects that the temperature inside the cabinet 1 is high, the control unit opens the fourth valve 62 and the second valve 71 and closes the third valve 101 and the first valve 61, so that the air inside the air bladder 6 is discharged to the inside of the circulation passage by the circulation pump 3. The air bag 6 contracts to enable the floating seat 2 to sink, so that more circulating pipelines are immersed in water, and further better heat dissipation is achieved. When the temperature sensor detects that the temperature inside the cabinet 1 is low, the control unit opens the first valve 61 and closes the third valve 101, the fourth valve 62 and the second valve 71, so that the air inside the cabinet wall pipe 10 is discharged to the inside of the air bag 6 through the circulation pump 3. And then make and avoid the intraductal air density reduction, reduce the heat dissipation of cabinet wall, avoid the internal temperature of cabinet body 1 when winter to hang down excessively.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
