[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention; See also Figure 1-5 , the present invention provides the following embodiment 1: An insulation box used in a water substation includes a substation box 1 and a sunshade mechanism 10 installed on a water base station. The outer side of the substation box 1 is integrally formed with an insulation layer 2. The gap between the substation box 1 and the insulation layer 2 is an adjustment cavity 3. An evaporation box 4 is fixedly installed on one side of the insulation layer 2. A ventilation hole 5 for connecting the insulation layer 2 and the evaporation box 4 is provided at the connection between the insulation layer 2 and the evaporation box 4. An exhaust port 6 is provided on the top of the insulation layer 2. An evaporation plate 7 is fixedly installed on the inner side of the evaporation box 4. A connecting pipe 8 is fixedly installed on the bottom of the evaporation box 4. The bottom end of the connecting pipe 8 extends to the outside of the water base station. The bottom of the evaporation plate 7 is connected to a moisture-absorbing cotton 9, and the bottom end of the moisture-absorbing cotton 9 extends to the inside of the connecting pipe 8.

[0018] The bottom end of the connecting pipe 8 is rotatably connected to a connecting head 81, and a movable end 11 is hinged on the inner side of the connecting head 81. The part of the movable end 11 located outside the connecting head 81 is integrally formed with a drainage pipe 12. The drainage pipe 12 is connected to the interior of the connecting pipe 8. The bottom end of the drainage pipe 12 is fixedly connected to a pull rope 13, and the other end of the pull rope 13 is connected to the evaporation box 4; a booster pump 14 is fixedly installed in the connecting pipe 8, and an overflow port is opened on the evaporation box 4.

[0019] Water surface evaporation is a natural cooling process in which evaporation absorbs heat. The water in the connecting pipe 8 is pumped upward by the booster pump 14, absorbed by the moisture-absorbing cotton 9 and transferred to the evaporation plate 7, thereby expanding the evaporation area. The evaporation and heat absorption process of water is utilized to cool the passing air, and then the air is introduced into the regulating cavity 3 between the substation box 1 and the insulation layer 2 through the vent 5. Under high temperature conditions in summer, the evaporation efficiency can be ensured to maintain the low-temperature working range of the substation box 1 and avoid excessive temperature. Under normal temperature or low temperature conditions, the booster pump 14 stops working and the insulation layer 2 is used for thermal insulation.

[0020] Since the substation box is installed on an above-water base station, and the water temperature varies at different depths, the release length of the pull rope 13 is adjusted according to the required cooling temperature requirements, so that the depth of the bottom end of the drainage pipe 12 is adjusted to a suitable position. For example, in summer, the surface temperature is 28°C → the thermocline temperature drops by 3-5°C per meter → the bottom temperature drops by 4-8°C.

[0021] This full utilization of the water resources of the floating substation can effectively regulate the thermal insulation of the substation box 1, thereby increasing the service life and stability of the electrical components in the substation box 1.

[0022] The outside of the connecting pipe 8 and the drainage pipe 12 are both wrapped with an insulation sleeve 15; the insulation sleeve 15 prevents the cold water pumped up from the lower layer from being excessively affected by the temperature of other deep water bodies during the transportation process through the connecting pipe 8 and the drainage pipe 12.

[0023] The outside and inside of the substation box 1 are integrally formed with evenly distributed heat exchange fins 16, and the heat exchange fins 16 on the outside of the substation box 1 are located inside the regulating cavity 3; the heat exchange fins 16 can accelerate the heat exchange speed between the inside of the substation box 1 and the regulating cavity 3, thereby improving the cooling effect of the substation box 1.

[0024] An anti-blocking net 17 is fixedly installed on one end of the drainage pipe 12 away from the connecting pipe 8, and a guide plate 18 is fixedly installed below the drainage pipe 12. The guide plate 18 is flat.

[0025] The anti-blocking net 17 prevents other foreign objects in the water from directly entering the interior of the drainage pipe 12 and causing blockage, thereby ensuring smoothness when pumping water, and the guide plate 18 can change the water flow and adjust the direction of the drainage pipe 12 to a certain extent. The weight of the guide plate 18, the anti-blocking net 17 and the drainage pipe 12 can enable the lower end of the drainage pipe 12 to drop to a certain depth when the pull rope 13 is released.

[0026] See also Figure 1-3 , the present invention further provides Example 2 based on Example 1: The sunshade mechanism 10 includes a fixed ring 101 fixedly installed on the water base station, a movable ring 102 is provided on the outside of the fixed ring 101, and evenly distributed support rods 103 are hinged on the movable ring 102. The support rods 103 are located at one end of the inner circle of the movable ring 102 and are connected to the fixed ring 101. A sunshade cloth 104 is fixedly connected between two adjacent support rods 103; the color of the sunshade cloth 104 is black, and the unfolded shape of the sunshade cloth 104 is fan-shaped.

[0027] By rotating the outer movable ring 102 and utilizing the position change of the movable ring 102 and the fixed ring 101, the support rod 103 can be extended or retracted. When the ambient temperature around the water substation is too low, the support rod 103 is extended, and the sunshade cloth 104 between the two support rods 103 can be unfolded, thereby shielding the water surface around the water base station, avoiding direct sunlight, and suppressing the evaporation of the water surface, which helps to suppress evaporation, reduce the cooling effect of the water surface, reduce latent heat loss, and help maintain water temperature. The black sunshade cloth 104 can absorb heat energy in the light, further increase the temperature around the substation box 1, and reduce temperature loss inside the substation box 1.

[0028] A strip-shaped slide groove 19 is formed at one end of the support rod 103 located on the inner circle of the movable ring 102 , and the top of the fixed ring 101 extends to the inner side of the strip-shaped slide groove 19 and is slidably connected to the inner wall of the strip-shaped slide groove 19 .

[0029] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
