Description

Technical Field

[0001] The utility model relates to the field of storage batteries, in particular to an automatic fire extinguishing type wind power generation energy storage device. Background Art

[0002] Due to the common severe conditions in my country's high latitudes and remote areas, such as high altitude, low air pressure, large temperature difference, low temperature, frequent and strong winds, etc., wind, solar and storage integrated mobile energy storage power stations are particularly important. They use clean and pollution-free energy as the power generation source, which is affected by the sunshine time, light intensity and / or wind force level and seasonality. It has little performance in the high-cold and high-altitude environment. On the contrary, mobile energy storage devices use lithium-ion batteries as energy storage, which are greatly affected by low air pressure and high and low temperatures. Therefore, when designing wind and solar connected mobile energy storage devices that can operate reliably and stably for a long time in the high-cold and high-altitude environment, it is necessary to consider the fire prevention measures of the batteries. If a fire occurs, the power generation equipment is located in a remote area and personnel cannot arrive in time to extinguish the fire, which will inevitably lead to equipment damage.

[0003] In order to solve the above-mentioned technical problems, the prior art provides many solutions, such as the existing document WO2022134748A1, which provides a lithium battery explosion-proof box device, which provides a lifting plate scheme to ensure the safety of the battery pack, and the battery pack of the device is equipped with a fire extinguishing sticker that can automatically extinguish a fire. However, there is still room for improvement in the fire extinguishing sticker layout scheme of the device. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic fire extinguishing wind power generation energy storage device, which can ensure that the fire extinguishing structure and the battery have an effective spacing distance, solve the problem that the use of fire extinguishing stickers affects the normal heat dissipation of the battery and increases the safety hazards of battery use, and the technical solution provided by the utility model can effectively ensure the installation stability of the fire extinguishing structure and the battery.

[0005] In order to solve the above technical problems, the utility model specifically provides the following technical solutions: an automatic fire-extinguishing wind power generation energy storage device, including a battery, a first substrate capable of suppressing thermal runaway and extinguishing fire is arranged on the surface of the battery, a support member is arranged between the first substrate and the battery, the support member has a second support sleeve, and both end surfaces of the second support sleeve are in contact with the first substrate and the battery respectively.

[0006] By arranging the first substrate on the surface of the battery, when the battery has a high temperature and runs out of control and a fire occurs, the first substrate can be used to automatically extinguish the fire, preventing the battery from further burning and causing the fire to expand. By arranging a support member between the first substrate and the battery, a certain distance is maintained between the two, so that normal airflow can flow on the surface of the battery, ensuring its effective heat dissipation space, and solving the problem that the use of fire extinguishing stickers affects the normal heat dissipation of the battery and increases the safety hazard of battery use. In addition, by arranging the first substrate and the second support sleeve of the support member, collision protection can be provided for the outside of the battery, and friction protection can be provided for the surface of the battery. For example, external impact force can be absorbed by the deformation of the first substrate and the second support sleeve.

[0007] It should be noted that the first substrate can be arranged on any surface of the battery. Of course, the first substrate in the utility model can also be arranged on the surface of the mounting base sleeve, generator and other components of the utility model to form an effective fire prevention and fire extinguishing effect.

[0012] The fasteners mechanically fix the position of the first substrate relative to the battery by means of the first fastening plate and the second fastening plate, so that the first substrate is not easily separated from the battery surface due to certain reasons, such as high temperature causing the first substrate surface to separate from the adhesive layer. The fasteners also prevent the first substrate and the battery from becoming loose.

The design of the second through holes is used to increase the airflow range on the battery surface, ensure the normal and effective heat dissipation of the battery, and on the other hand, reduce the manufacturing cost of the first substrate. When a fire occurs, the contact surface between the flame and the first substrate can be expanded through the second through holes and the first through holes, thereby increasing the speed at which the first substrate reacts.

[0015] According to one embodiment of the utility model, the first substrate has a cavity inside, and the first columns are stacked in the cavity; in this way, when a local flame occurs, the first substrate at the corresponding position melts and releases the first columns inside to the area where the fire occurs, so that the fire can be extinguished in a concentrated manner to avoid the situation of insufficient fire extinguishing materials.

[0016] The first substrate and / or the first column are made of fire extinguishing material.

[0018] According to one embodiment of the utility model, the mounting base has a partition plate for separating the generator and the battery, and a through hole is provided on the partition plate for the circuit to pass through. The partition plate is used to prevent the generator and the battery from coming into close contact, which may cause overheating and pose a safety hazard. The generator of the utility model is an existing wind turbine generator, which will not be described in detail here. The power generation principle it adopts is: using wind power to drive the windmill blades to rotate, and then increasing the rotation speed through a speed increaser to drive the generator to generate electricity.

For example, external impact force can be absorbed by the deformation of the first substrate 70 and the second support sleeve 92.

[0035] It should be noted that the first substrate 70 can be arranged on any surface of the battery 60. Of course, the first substrate 70 in the utility model can also be arranged on the surface of the mounting base sleeve 30, the generator 50 and other components of the utility model to form an effective fire prevention and fire extinguishing effect.

[0036] The first support sleeve 91 is sleeved on the outer side of the second support sleeve 92, and the inner side of the first support sleeve 91 is connected to the outer wall of the second support sleeve 92 through a support connecting plate 93 of a plate-like structure. The setting of the support connecting plate 93 can realize the linkage between the second support sleeve 92 and the first support sleeve 91, and when facing the external force, the first support sleeve 91 and the second support sleeve 92 can be deformed at the same time.

[0037] By setting up multiple support sleeves, the effective supporting area of ​​the entire support member 90 and the first substrate 70 and the battery 60 surface is increased, so as to reduce or avoid the possibility of local close contact between the first substrate 70 and the battery 60. In addition, the buffering protection effect of the multiple support sleeves is also better, and the support sleeves are set into an annular sleeve structure, which can reduce the manufacturing cost of the support sleeves and reduce the contact area between the first support sleeve 91 and the second support sleeve 92 and the first substrate 70 and the battery 60, so as to reduce the impact on the heat dissipation of the battery 60.
