Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery exchange cabinets, and in particular relates to a battery exchange cabinet with a fire-fighting function. Background Art

[0002] At present, the use of shared electric bicycles is becoming more and more popular, but the battery life of electric bicycles has always been a difficult problem to overcome. In order to solve the problem of battery life of electric bicycles, the concept of a smart battery exchange cabinet has been proposed on the market.

[0003] Currently, most battery swap cabinets on the market are upright, and batteries are replaced by pulling and plugging in the horizontal direction. However, during the use of such charging cabinets, due to differences in the operator's thrust, the charging connector and the charging interface may not be properly connected, resulting in charging sparks and increasing the risk of fire. In response to this, some manufacturers have proposed a battery swap cabinet solution with a rotatable battery compartment. For example, a Chinese patent with publication number CN219322122U proposes a charging cabinet, comprising: a cabinet body, a socket being provided on the side wall of the cabinet body; at least one battery compartment, the battery compartment being arranged in the cabinet body, close to the socket, and a charging interface being provided at the bottom of the battery compartment; a battery compartment rotation drive structure, the battery compartment can be driven to rotate by the battery compartment rotation drive structure, so that it can be converted between two states: the open end facing the socket and the open end facing vertically upward.

[0004] The battery swap cabinet mentioned in the above patent can effectively solve the problem of improper connection of the charging connector through the design of a rotating battery compartment, and can effectively avoid some fire risks. However, it is still subject to fire risks due to factors such as the charging circuit and the battery's own status. Therefore, a fire protection solution that can be applied to a rotating battery compartment is extremely important. Utility Model Content

[0025] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0026] Example:

[0027] See Figure 1-Figure 3 A battery exchange cabinet with fire-fighting function includes a battery cabinet 1, a battery compartment 3 and a rotation drive structure 2 for controlling the rotation of the battery compartment 3 relative to the battery cabinet 1; a fire-fighting component is also provided on the battery compartment 3 / battery cabinet 1, and the fire-fighting component includes a fire-fighting pipe 6 connected to the battery compartment 3 at one end, and the other end of the fire-fighting pipe 6 is connected to a fire-fighting medium (water, etc.) after passing through a pump body 8. The central axis of the connecting part of the fire-fighting pipe 6 and the battery compartment 3 is consistent with the rotation axis of the battery compartment 3, and the battery compartment 3 rotates around the outer peripheral wall of the fire-fighting pipe 6 along its rotation axis.

[0028] The rotation drive structure 2 includes a drive motor 5 and a connection port. The battery compartment 3 is mounted on a rotating frame and can rotate thereon. The drive motor 5 is arranged on the battery compartment 3, and the connection port is placed on the rotating frame.

[0029] Or the driving motor 5 is arranged on the rotating frame, and the connection port is placed on the battery compartment 3;

[0030] The output shaft and the connection port (not shown) of the drive motor 5 can be fixed to each other;

[0031] The battery cabinet 1 / rotating frame is provided with a fixing frame for fixing the fire hose 6;

[0032] The battery cabinet 1 is composed of a frame 4 and a plurality of plates. The rotating frame can be two parallel plates with sockets fixed to the base frame. By providing an axis that can be removed from the socket on the battery compartment 3, the battery compartment 3 can be rotated on the rotating frame. In this embodiment, the drive motor 5 is fixed to the frame 4, and the connection port is used as a parallel replacement for an axis on the battery compartment 3 (the plate with the socket can no longer be used at this position). The fire hose 6 is used as another parallel replacement for the battery compartment 3. At the same time, the fixed frame includes a horizontally arranged connecting plate 10 fixed to the frame 4 and a vertically arranged limit support plate 11 fixed to the connecting plate 10. The fire hose 6 passes horizontally through the limit support plate 11 and then bends downward to pass through the connecting plate 10.

[0033] The firefighting medium is placed in a firefighting box 7 , which is disposed in the battery cabinet 1 and below the battery compartment 3 .

[0034] Among them, the battery compartment 3 is also connected to a liquid outlet pipe 12, and one end of the liquid outlet pipe 12 connected to the battery compartment 3 is placed above the fire pipe 6, and is preferably set to a position higher than the battery. This position setting method is to ensure that the fire-fighting medium can more comprehensively cover the batteries in the battery compartment 3. Among them, the other end of the liquid outlet pipe 12 is placed in the fire box 7 and is not connected to the fire box 7.

[0035] The battery compartment 3 is provided with two adapters, and the fire hose 6 and the liquid outlet pipe 12 are respectively connected to an adapter. The adapters enable the outer wall of the battery compartment 3 provided with the adapters to rotate along the outer wall of the fire hose 6 and the liquid outlet pipe 12 during the rotation of the battery compartment 3.

[0036] The adapter can adopt a structure similar to a bearing. Under this structure, the outer ring of the bearing is fixed to the battery compartment 3, and the inner ring of the bearing is fixed to the fire pipe 6 or the liquid outlet pipe 12. A seal is provided on the adapter to prevent the fire protection medium in the battery compartment 3 from flowing out.

[0037] Among them, the liquid outlet pipe 12 can be in the form of a hose. When a hose is used, the connection part between it and the battery compartment 3 can be connected without an adapter. Of course, the liquid outlet pipe 12 can also be in the form of a hard tube as a whole. In this form, the rotation of the battery compartment 3 will cause the liquid outlet pipe 12 to generate a moving path on the fire box 7. Therefore, it is necessary to open a corresponding long hole on the fire box 7. At the same time, it is necessary to add a corresponding structure to prevent the end of the liquid outlet pipe 12 placed in the fire box 7 from detaching from the fire box 7. For example, a limiter with a diameter greater than the width of the long hole is added to the end and placed in the fire box 7.

[0038] In addition, a temperature sensor is provided in the battery compartment 3 , and a solenoid valve 9 is connected to the fire-fighting pipe 6 .

[0039] Working principle and process:

[0040] When using the product of this solution, the temperature inside the battery compartment 3 is detected by a temperature sensor. When the temperature is higher than the set temperature threshold, the fire-fighting medium is controlled to enter the battery compartment 3 through the pump body 8 to achieve a fire-fighting effect on the battery. At the same time, the fire-fighting medium in the battery compartment 3 flows back to the fire-fighting box 7 through the liquid outlet pipe 12 when it reaches the position of the liquid outlet pipe 12, so that the fire-fighting medium can circulate in the battery compartment 3 and achieve cooling.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
