As an alternative embodiment of the present embodiment, the cabinet 10 may be an integrally formed component, or the door 30 may be an integrally formed component, or the cabinet 10 is an integrally formed component and the door 30 is also an integrally formed component. Specifically, the door 30 and the door waterproof portion 301 may be integrally formed, the cabinet 10 may be integrally formed, and the necessary connection portions may be connected by welding or the like, please refer to fig. 5, a water outlet 104 may be disposed at the bottom of the cabinet 10, when water enters the cabinet 10, the water in the cabinet 10 may be discharged through the water outlet 104 at the bottom, so as to prevent the liquid from remaining in the cabinet 10, and prevent the cabinet 10 from rusting. In addition, the bottom of the battery compartment 20 may also be provided with a drainage hole 202 (refer to fig. 3), so as to prevent the liquid from remaining in the battery compartment 20 after being soaked in water.

As an alternative embodiment of this embodiment, please refer to fig. 12, the battery replacement cabinet further includes a water level sensor 13, the water level sensor 13 may be disposed inside the cabinet body 10, and the control assembly 40 may be connected to the water level sensor 13. In the concrete application, when trading when the position that the electric cabinet was located and great degree ponding appears, trade the electric cabinet and probably partially immerse in water, at this moment, can utilize the inside level sensor 13 of the cabinet body 10 to detect current water level, reach when probably influencing the normal operating of trading the electric cabinet when the water level, level sensor 13 can be triggered, and through control assembly 40 with the power disconnection of trading the electric cabinet, and send relevant signal to rear end server, can continue the operation after maintenance personal overhauls the electric cabinet, thereby eliminate the potential safety hazard that ponding brought for trading the electric cabinet.

As an alternative to this embodiment, please refer to fig. 2 again, a control chamber 101 is disposed at the top of the cabinet 10, the control assembly 40 can be disposed in the control chamber 101, the control assembly 40 is prevented from being directly immersed in water when water is accumulated, the water level sensor 13 can be disposed at the bottom of the cabinet 10, and the water level sensor 13 is triggered when the water level is close to the battery compartment 20. Specifically, the control room 101 can be opened and closed by the top cover 11 of the cabinet 10, and a waterproof structure similar to that in any one of the above embodiments can be provided between the top cover 11 and the control room 101, so as to prevent rainwater from entering the control room 101, and meanwhile, a sealing strip and other structures can be added between the top cover 11 and the cabinet 10, so as to further improve the waterproof effect of the control room 101.

The battery replacing cabinet provided by the embodiment of the application has the following beneficial effects: compared with the prior art, the power transformation cabinet provided by the embodiment of the application utilizes the battery compartment 20 of the cabinet body 10 to store the battery 50, realizes the opening and closing of the battery compartment 20 through the compartment door 30 connected with the cabinet body 10, the side wall of the battery compartment 20 is provided with the heat dissipation fan and the pressure relief window 22, the cabinet body 10 is internally provided with the control component 40, and the control component 40 is utilized to control the starting and stopping of the heat dissipation fan 21. Thus, when the battery 50 in the battery compartment 20 is being charged and generates a large amount of heat, the control component 40 can be used to turn on the heat dissipation fan 21, and the heat dissipation fan 21 can exhaust the hot air in the battery compartment 20 from the pressure relief window 22, so as to reduce the temperature in the battery compartment 20 and prevent the heat in the battery compartment 20 from concentrating. Meanwhile, when the battery 50 in the power exchange cabinet is burnt or exploded due to unexpected reasons such as collision, the air pressure in the battery compartment 20 is increased sharply, and at the moment, the pressure relief window 22 can timely relieve the air pressure in the battery compartment 20, so that potential safety hazards caused by excessive air pressure in the battery compartment 20 are eliminated.

The above description is only a preferred embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
