Description

Technical Field

[0001] The utility model relates to a power exchange cabinet, in particular to an anti-evaporation structure of a water tank of a fire extinguishing system of the power exchange cabinet. Background Art

[0002] At present, electric bicycles are becoming more and more popular. For people who frequently use electric bicycles, such as food delivery personnel, couriers, etc., the battery of the electric bicycle may not be enough. If the electric bicycle is charged, there will be an embarrassing situation that the electric bicycle cannot be used, which will undoubtedly affect the efficiency of the staff. Therefore, battery swap cabinets came into being. When the electric bicycle is out of power, you can conveniently take out the charged battery from the battery swap cabinet, and the dead battery can be stored in the cabinet for charging, which brings great convenience to users of electric motorcycles.

[0003] Generally, battery swap cabinets are divided into multiple grids, each grid is equipped with a battery for battery swap. Currently, most batteries are lithium-ion batteries, and during use, especially when overheated, lithium-ion batteries will have risks of combustion and explosion. Moreover, battery swap cabinets are set in areas with dense personnel. Therefore, many battery swap cabinets are equipped with water-cooled fire extinguishing systems. One of the fire extinguishing methods is water immersion fire extinguishing. This method requires a fire sprinkler to be installed inside the grid and a water storage tank to be installed on the top of the cabinet. When there is a fire, the water in the water tank will be sprayed out in large quantities from the fire sprinkler through the pipe, thereby playing a role in extinguishing the fire. In order to ensure water output, the water storage tank will not be sealed, and a larger water injection hole will be left. One is for adding water, and the other is to facilitate the rapid entry of air to balance the internal and external atmospheric pressure when water is released in the event of a fire to ensure smooth water output.

[0004] However, the above structure has a defect, because the battery swap cabinet is often outdoors, dust and other objects can easily enter the water tank through the water injection hole, and the water in the water tank can easily evaporate and be lost through the water injection hole, resulting in insufficient water when there is a fire.

[0005] Therefore, the applicant has designed an anti-evaporation structure for the water tank of the power exchange cabinet fire extinguishing system to solve the above problems. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides an anti-evaporation structure for a water tank of a fire extinguishing system of a power exchange cabinet.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] The anti-evaporation structure of the water tank of the fire extinguishing system of the power exchange cabinet includes a water storage tank, which is characterized in that: the water storage tank is provided with an air hole, and the air hole is connected to the outside through an air one-way valve.

[0009] The water storage tank is provided with a water injection hole and a sealing member capable of closing the water injection hole.

[0010] The sealing element is a water valve.

[0011] The water injection hole is arranged on the top surface or the side surface of the water storage tank.

[0012] The air holes are arranged on the side surface or the top surface of the water storage tank.

[0013] The beneficial effect of the utility model is that an air hole is also provided on the water tank, and an air one-way valve is provided in the air hole, so that the water injection hole can be sealed, and the water in the water tank will not evaporate through the water injection hole. When a fire occurs, the outside air can quickly enter the water tank through the air one-way valve, thereby ensuring that the water in the water tank is released smoothly, and the water in the water tank will not evaporate through the air one-way valve.
