Description

A type of waterborne carrier Technical Field

[0001] This invention relates to the field of water transportation, and more specifically, to a waterborne vehicle. Background Technology

[0002] If a battery on a watercraft goes out of control and cannot be extinguished in time, it will inevitably have a safety impact on the watercraft. Therefore, it is necessary to design a device that can extinguish the fire of the out-of-control battery in a timely manner without discharging the battery. Summary of the Invention

[0003] The purpose of this invention is to provide a waterborne carrier, which includes a hull and a battery module installed inside the hull. When the battery module goes out of control, the battery module is extinguished and discharged from the hull.

[0004] Optionally, the system also includes a hatch connected to the hull, the hatch containing a battery module, which is extinguished and removed from the hatch when it malfunctions.

[0005] Optionally, it also includes two one-way valves, one of which allows water to enter the hatch, and the other of which allows water to exit the hatch.

[0006] Optionally, it also includes a suction pump and a discharge pump, the suction pump allowing water to enter the hatch and the discharge pump allowing water to exit the hatch.

[0007] Optionally, the battery module has an explosion-proof housing so that if one of the battery modules malfunctions, it will not affect the other battery modules.

[0008] Optionally, the hatch is located on the side of the hull. When the battery module goes out of control, the hatch opens and the battery module is discharged from the waterborne carrier.

[0009] Optionally, the battery module is connected to a compression spring, which discharges the battery module from the waterborne carrier when the hatch is opened.

[0010] Optionally, the waterborne carrier further includes an auxiliary power source, which acts as a power supply device after the battery module is installed.

[0011] Optionally, the waterborne carrier also includes sensors that can automatically detect whether the battery module is out of control.

[0012] Optionally, the hatch can be opened automatically or manually. Attached Figure Description

[0018] The following embodiments further illustrate the technical solutions of this application. It should be understood that the specific embodiments described herein are merely for explaining this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not all of them.

[0019] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] This application provides a waterborne carrier, which includes a hull 100 and a hatch 200. The hatch 200 is connected to the hull 100 and a battery module 300 is installed inside the hatch 100. When the battery module 300 goes out of control, the hatch 200 opens, the battery module 300 is extinguished and discharged from the hull 100 and the hatch 200.

[0022] Specifically, in one embodiment, the aquatic carrier of this application further includes two one-way valves, one of which, 201, allows water to enter the hatch 200, and the other, 202, allows water to exit the hatch 100. The advantage of this one-way valve configuration is that the battery module 300 inside the hatch 200 is always in contact with water; if the battery module 300 malfunctions, the water can immediately extinguish the fire.

[0023] Specifically, in another embodiment, the waterborne carrier of this application further includes a water intake pump 203 and a water discharge pump 204. The water intake pump 203 allows water to enter the hatch 200, and the water discharge pump 204 allows water to exit the hatch 200. The advantage of this arrangement of the water intake pump 203 and the water discharge pump 204 is that the battery module 300 inside the hatch 200 is always in contact with water, and if the battery module 300 goes out of control, the water can immediately extinguish the fire.

[0024] Of course, normally, when one battery module 300 malfunctions, it will affect the other battery modules 300. However, in this application, each battery module 300 has an explosion-proof housing 301, so when one battery module 300 malfunctions, it will not affect the other battery modules 300. Therefore, if the operator does not notice in time that a battery module 300 has malfunctioned or the hatch 200 cannot be opened due to a fault, it will not cause any damage to the watercraft in a short period of time.

[0025] In another embodiment, the hatch 200 is located on the side 102 of the hull 100. When the battery module 300 goes out of control, the hatch 200 opens and the battery module 300 is discharged from the water carrier.

[0026] Specifically, the battery module 300 is connected to the compression spring 400. After the compression spring 400 is connected to the battery module 300, the compression spring 400 is in a compressed state. However, due to the obstruction of the hatch 200, the other side of the compression spring 400 will not eject the battery module 300 from the watercraft. When the hatch 200 is opened, the compression spring 400 returns to its elasticity, at which point the battery module 300 is discharged from the watercraft.

[0027] Preferably, the waterborne carrier also includes an auxiliary power source 500. When the battery module 300 is damaged, the auxiliary power source 500 can act as a power source. Of course, the auxiliary power source 500 in this application can be any known power source other than the battery module 300.

[0028] Preferably, the waterborne carrier also includes a sensor 600, which can automatically detect whether the battery module 300 is out of control. When the battery module 300 is detected to be out of control, the hatch 200 can be opened and the out-of-control battery module 300 can be discharged from the waterborne carrier.

[0029] In addition, in the embodiments of this application, the hatch 200 can be opened automatically or manually.

[0030] The above embodiments are merely illustrative of the principles and effects of this application. Any person skilled in the art can modify or alter the above embodiments without departing from the purpose of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the purpose disclosed in this application should still be covered by the claims of this application.
