[0022] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0023] like Figure 1 As shown, this utility model provides a rainproof spray device for an electric ship battery swapping base, comprising: The nozzle assembly includes an air duct 1 and a spray pipe 2 disposed at the upper end of the air duct 1. The spray pipe 2 has multiple spray holes 3 on its wall. The upper and lower ends of the spray pipe 2 are respectively provided with an upper airflow limiting cover 4 and a lower airflow limiting cover 5. The air duct 1 can be vertically and vertically disposed in the middle of the electrical connector mounting plate 6 of the battery swapping base. An air supply assembly is connected to the air duct 1. The detection component is used to detect the separation of the battery pack from the battery swapping base; The control unit is connected to the detection component and the air supply assembly, and controls the air supply assembly to supply air to the nozzle assembly based on the detection results of the detection component.

[0024] Specifically, to address the problem that existing technologies for rain protection of battery swapping base electrical connectors often employ passive protection structures such as waterproof covers and sealing caps, which require installation and have limited protective effects, this utility model provides a rain-proof spray device for electric ship battery swapping bases. This device features a nozzle assembly that can be raised and lowered and is positioned in the middle of the electrical connector mounting plate 6 of the battery swapping base. The nozzle assembly is supplied with air by an air supply component. In rainy weather, after the detection component detects the separation of the battery pack from the battery swapping base, the control unit controls the air supply component to supply compressed air to the nozzle assembly. The nozzle assembly's spray pipe 2, through multiple spray holes 3 opened in its pipe wall, can spray airflow outwards, forming a uniformly diffused air curtain above the electrical connector, preventing rainwater from contacting the electrical connector and achieving automatic rain protection. Furthermore, the compressed air curtain can quickly cover the area surrounding the electrical connector, providing timely rain protection after the battery pack separates from the battery swapping base, thus improving the protective effect.

[0025] Furthermore, rain detection can be performed using rain sensors and infrared raindrop sensors equipped on the electric vessel, which can then be connected to the control unit.

[0026] Optionally, two rings of nozzles 3 are formed on the wall of the spray pipe 2 from top to bottom. Multiple nozzles 3 in each ring are evenly distributed along the circumference of the spray pipe 2, and the two rings of nozzles 3 are arranged alternately.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the nozzles 3 are arranged in two rings, one above the other, and the two rings of nozzles 3 are staggered to ensure uniform airflow and cover the top of each electrical connector on the electrical connector mounting plate 6.

[0028] Optionally, the upper airflow limiting cover 4 is a disc-shaped structure, and the lower airflow limiting cover 5 is an annular structure.

[0029] Specifically, the upper airflow limiting cover 4 is installed on the upper end of the injection pipe 2, and the lower airflow limiting cover 5 is fitted on the lower outer periphery of the injection pipe. The upper airflow limiting cover 4 and the lower airflow limiting cover 5 are used to control the airflow direction.

[0030] Optionally, the electrical connector mounting plate 6 has a lifting hole in the middle, through which the vent duct 1 slides.

[0031] Specifically, the ventilation duct 1 is installed in a height-adjustable manner by passing through the lifting hole in the middle of the electrical connector mounting plate 6, and multiple electrical connectors are arranged around the lifting hole.

[0032] In this embodiment, four electrical connectors are arranged around the lifting hole.

[0033] Optionally, it also includes a lifting assembly, which includes: The nozzle pressure plate 7 is located on the lower side of the electrical connector mounting plate 6 and is connected to the outer periphery of the air duct 1. The nozzle fixing plate 8 is spaced below the nozzle pressure plate 7; Elastic component 9 is disposed between nozzle fixing plate 8 and nozzle pressure plate 7.

[0034] Specifically, the elastic component 9 is in a pre-compressed state, and under its elastic force, it pushes the nozzle pressure plate 7 upward, which can make the nozzle assembly in a raised state. At the same time, the nozzle assembly can be pressed down by the battery pack to store energy for the elastic component 9; the nozzle fixing plate 8 can be fixed inside the battery swapping base.

[0035] In this embodiment, the elastic component 9 is a spring. The spring is sleeved on the outside of the ventilation duct 1 and is compressed by the spring pressure plate to ensure that when the battery pack is installed on the battery swapping base and connected to the electrical connector, the nozzle assembly can compress the spring and move downward without affecting the insertion of the electrical connector. Furthermore, during the lifting of the battery pack, the nozzle assembly can automatically move upward under the action of the spring.

[0036] Optionally, the air supply assembly includes an air compressor, an air tank, and an air delivery pipe connected in sequence, with the air delivery pipe connected to the lower end of the air inlet duct 1.

[0037] Specifically, the compressed air output by the air compressor is pressure-stabilized by the air storage tank and then delivered to the nozzle assembly through the air delivery pipe. The air delivery pipe may include a high-pressure air delivery rigid pipe and a high-pressure air delivery flexible pipe. The high-pressure air delivery flexible pipe is connected to the lower end of the air duct 1 to form a stable compressed air source.

[0038] In this embodiment, the lower end of the ventilation duct 1 is provided with a duct connector 10, which can be easily connected to a high-pressure air hose.

[0039] Optionally, the gas pipeline is equipped with a solenoid valve.

[0040] Specifically, the solenoid valve can control the opening and closing of the air supply pipe, thereby controlling the air supply to the nozzle assembly. The solenoid valve can be electrically controlled by the control unit.

[0041] Optionally, it also includes a pulse power supply controller, which is connected to the control unit and the solenoid valve and is used to control the power supply to the solenoid valve.

[0042] Specifically, the pulse power supply controller can provide pulse power to the solenoid valve, which in turn causes the nozzle assembly to spray compressed air in a pulsed manner, forming an air curtain that spreads evenly in all directions, preventing rainwater from contacting the electrical connector.

[0043] Optionally, the detection component includes a distance sensor or a pressure sensor.

[0044] Specifically, the detection component only needs to be able to detect whether the battery pack has left the battery swapping base. A distance sensor can be used, installed on the hanger of the battery swapping equipment, to detect its height from the battery swapping base. Alternatively, a pressure sensor can be used, installed on the upper side of the battery swapping base, where the pressure drops significantly when the battery pack leaves.

[0045] In rainy weather, the detection component detects the separation status of the battery pack from the battery swapping base. When the battery pack leaves the battery swapping base, the control unit activates the pulse power supply controller to supply power to the solenoid valve. The solenoid valve controls the opening and closing of the compressed air channel, so that the compressed air passes through the air duct 1 and spray pipe 2 nozzle 3 of the nozzle assembly in pulse form, forming an air curtain that spreads evenly in all directions, preventing rainwater from contacting the electrical connector.

[0046] like Figure 4 As shown, this utility model also provides a battery swapping base, including the rainproof spray device of the above-mentioned electric ship battery swapping base.

[0047] Specifically, the battery swapping base is equipped with the aforementioned rainproof spray device for electric ship battery swapping bases. When swapping batteries in rainy weather, the spray nozzle assembly can be raised synchronously when the battery pack leaves the battery swapping base, and the air supply component can be activated to supply air to the spray nozzle assembly, quickly forming a compressed air curtain above the electrical connector to prevent rainwater from entering the electrical connector on the battery swapping base.

[0048] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
