The condenser pipe 4 is controlled by the temperature control switch 2 to circulate water to cool the inside of the cabinet 1. The cooling unit 9 and the exhaust fan 5 circulate air to cool the inside of the cabinet 1, which helps to improve the cooling effect and achieve the purpose of energy saving and emission reduction. The condenser pipe 4 is an S-shaped pipe.

[0030] like Figure 4、 Figure 5 As shown in the figure, the lower end of the cabinet 1 is provided with a guide rod 11, the lower end of the cabinet 1 is rotatably provided with a ball screw 12, the ball screw 12 is arranged at the right side of the guide rod 11, the upper end of the ball screw 12 is provided with a gear a 13, the lower end of the ball screw 12 is provided with a threaded groove, and the right end of the cabinet 1 is provided with a glass cover 14.

[0031] In this example, the floating ball 92 is guided by the guide rod 11 according to the up-and-down floating of the liquid surface, and the filter cotton disc 10 is prevented from being wetted by rainwater by the glass cover 14, so as to lose the effect of filtering moisture.

[0032] As shown in the figure, Figure 4 The cold air assembly 9 includes a telescopic air inlet pipe 91 arranged at the lower end of the cabinet 1 and a floating ball 92 arranged at the lower end of the air inlet pipe 91, the floating ball 92 is slidably arranged on the guide rod 11, and the air inlet pipe 91 includes a hard pipe 911 and a flexible pipe 912 connected with the hard pipe 911.

[0033] As shown in the figure, Figure 5 The floating ball 92 is provided with an air inlet 921, the side wall of the floating ball 92 is provided with a connecting rod 922, the right end of the connecting rod 922 is provided with a threaded sleeve 923, and the threaded sleeve 923 is sleeved on the ball screw 12.

[0034] In this example, the threaded sleeve 923 is provided with threads matched with the threaded groove, and the air inlet pipe 91 can input humid cold air into the cabinet 1 through the air inlet 921.

[0036] As shown in the figure, Figure 2 The lower end of the filter cotton disc 10 is provided with a gear b 101 engaged with the transmission tooth 20.

[0037] In this example, the moisture in the humid cold air is filtered under the action of the filter cotton disc 10, so that the air entering the cabinet 1 is dry cold air, the filter cotton disc 10 is driven to rotate under the action of the gear b 101, so that the filter cotton disc 10 can switch to keep dry, the part of the filter cotton disc 10 outside the cabinet 1 is illuminated by sunlight, so that the moisture inside evaporates, so that the filter cotton disc 10 always keeps dry; the filter cotton disc 10 is made of superabsorbent resin.

[0041] The working process is as follows:

[0042] When the temperature control switch 2 senses that the inside of the cabinet 1 is overheated, the water pump 41 and the exhaust fan 5 are started, and the water in the water storage pool 7 is pumped up by the water pump 41 through the water inlet 42, and the s-shaped pipe is used to cool the power transformation cabinet 3, and the water is discharged back into the water storage pool 7 through the water outlet 43;

[0043] After the exhaust fan 5 is started, the wet and cold air in the water storage pool 7 enters the air inlet pipe 91 through the air inlet 921, and is filtered by the filter cotton disc 10, so that the air entering the cabinet 1 is dry and cold air;

[0044] When the liquid level of the water storage pool 7 drops, the floating ball 92 drops, so that the threaded sleeve 923 drives the ball screw 12 to rotate, thereby driving the transmission teeth 20 to rotate, and the gear b101 is driven to rotate by the transmission teeth 20, thereby driving the filter cotton disc 10 to rotate, so that the filter cotton disc 10 can switch to keep it dry.
