Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement, and in particular to a battery replacement connection device with a self-balancing function. Background Art

[0002] Since battery boxes can provide green and clean electricity and save a lot of fuel for ship navigation, ship battery replacement technology is becoming more and more popular among ship owners.

[0003] For example, the authorization announcement number CN217239886U discloses an electrical connection device with a guiding function, a battery-swappable ship, and a charging and swapping station. The electrical connection device is used to achieve electrical connection with the battery box for charging and discharging operations. The electrical connection device includes a floating plate and a base. The floating plate is equipped with an electrical connector for achieving electrical connection. The floating plate is connected to the base along its length and width directions respectively so that the floating plate can move within its plane, thereby adjusting the electrical connector to a position where it can be electrically connected to the battery box. However, when the ship is changing the battery, because the ship is always in a state of constant change on the water surface, it is difficult for the electrical connector and the battery box's plug interface to always be in a horizontal state, which will cause the electric plug to wear or hard interference, seriously affecting the service life, and there are also safety hazards. In addition, the electrical connector may also be corroded by rain and sea water, posing a major safety hazard. Utility Model Content

[0018] 4.

[0024] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all included in the protection scope of the present invention.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figures 1 to 4 As shown, the utility model discloses a battery replacement connection device with a self-balancing function, including a container 1 and a battery pack arranged therein, wherein a discharge head is provided at the bottom of the battery pack and a charging head 100 is provided at the top thereof. In a preferred embodiment of the utility model, the battery pack can be arranged in series or in parallel, both of which fall within the protection scope of the utility model and will not be elaborated herein.

[0027] The container 1 is provided with an opening 11, and a supporting plate 2 adapted thereto is fixedly disposed in the opening 11, and the charging head 100 is fixedly disposed on the supporting plate 2. A deflection block 5 is also pivotally disposed on the supporting plate 2, and a counterweight block 3 is disposed below the deflection block 5. The four sides of the upper surface of the counterweight block 3 are fixedly connected to the deflection block 5 by a pull rope 4 so that the deflection block 5 is always in a horizontal state. The above design is ingenious, and the counterweight block 3 can keep the deflection block in a horizontal state under the action of gravity, that is, the charging head 100 is always in a horizontal state. It can ensure that when the ship is changing power, the ship is in a constantly changing state on the water surface, and when the crane hoists the battery box onto the ship, the discharge head and the charging head are always in a parallel state, which can avoid the occurrence of hard interference or wear and tear and extend the service life.

[0028] In this preferred embodiment, the bottom sides of the support plate 2 are fixed with limit plates 21, and the limit plates 21 are provided with limit holes 22. The deflection block 5 is provided with universal balls 51 on both sides, and the universal balls 51 are at least partially placed in the limit holes 22 and matched therewith. The universal balls 51 are used for connection, which can make the structural layout more compact, facilitate disassembly, replacement and maintenance, and greatly improve work efficiency. In addition, the counterweight block 3 is fixed with a level meter, which can monitor the position of the counterweight block 3 in real time to ensure precise accuracy.

[0029] Another key point of the present invention is that: the support plate 2 is provided with a symmetrically arranged pull plate 6, which is slidably arranged on the support plate 2 and is located above the charging head 100; when the pull plates 6 move towards each other and are in close contact, the pull plates 6 seal the container 1. When the pull plates 6 move towards each other and are in close contact, the charging head can be shielded to prevent seawater, rainwater or debris from falling onto the charging head, which can prevent short circuits and other situations, thereby improving safety and extending service life.

[0030] A rubber pad is fixed on the inner side of the pull plate 6, and the setting of the rubber pad can further play a sealing role. The support plate 2 is fixed on a guide rail 61, and a guide block 62 adapted thereto is provided on the guide rail 61, and a sliding seat 63 is fixed on the guide block 62, and the pull plate 6 is fixed on the guide block 62. The support plate 2 is also fixed with a fixed seat 64, and the fixed seat 64 is located between the sliding seats 63. A transmission arm 65 is pivotally provided on the fixed seat 64, and a connecting arm 66 is pivotally provided on the sliding seat 63, and the connecting arm 66 and the other end of the transmission arm 65 are pivotally connected. A torsion spring 67 is provided at the lower half of the connecting arm 66, and the other end of the torsion spring 67 is connected to the lower half of the transmission arm 65. Under the action of pressure, the transmission arm 65 and the connecting arm 66 can drive the pull plate 6 to move in opposite directions, which is convenient for the plugging of the charging head. After the operation is completed, the torsion spring 67 applies a force in opposite directions to the pull plate, driving the pull plate 6 to move in opposite directions until it is close.
