Embodiment 1

[0070] Such as figure 1 and figure 2 Shown is Embodiment 1 of the present invention. This embodiment provides a data disaster recovery storage device. The data disaster recovery storage device includes an inner tank 1 with a hollow cavity 11, and the hollow cavity 11 is filled with cooling liquid, and the cooling liquid surrounds Data Storage 2. Specifically in this embodiment, the outer wall of the liner 1 is inwardly recessed to form a groove for accommodating the data storage device 2, that is, the wall of the groove is integrally connected with the wall of the liner 1, specifically by welding, or sheet metal stamping, Or the way of flange installation to realize the above structure, which is not limited in the present invention. Through this structure, the data storage 2 can be installed outside the inner tank 1 without affecting the protection of the data storage 2 by the cooling liquid.

[0071] The inner tank 1 has an opening 12 through which cooling liquid can be i...

Embodiment 2

[0089] Such as image 3 Shown is Embodiment 2 of the present invention. The automatic pressure relief valve provided by this embodiment is basically the same as the automatic pressure relief valve of Embodiment 1. The difference is that in this embodiment, the movable part 72 is provided with a direction The plunger 723 protrudes from the pressure relief hole 711 , and the plunger 723 cooperates with the pressure relief hole 711 to improve the sealing performance of the pressure relief hole 711 . When the pressure difference causes the plunger 723 to escape from the pressure relief hole 711 , the pressure relief hole 711 is opened, and the high temperature and high pressure steam can be discharged through the pressure relief hole 711 . In this embodiment, the pressure relief hole 711 is completely filled by the plunger 723 to ensure that the pressure relief hole 711 is sealed.

Embodiment 3

[0091] Such as Figure 4 Shown is Embodiment 3 of the present invention, the automatic pressure relief valve provided by this embodiment is basically the same as that of Embodiment 2, the difference is that in this embodiment, the length of the plunger 723 is shorter , when the movable part 72 is in the first position, only part of the pressure relief hole 711 is filled by the plunger 723, so the movable part 72 can be lifted up for a short distance to make the pressure relief hole 711 discharge high-temperature and high-pressure steam. In addition, the end of the plunger 723 is provided with a chamfer, so when the movable part 72 moves from the second position to the first position, the plunger 723 can enter the pressure relief hole 711 relatively easily, preventing the plunger 723 from being stuck in the pressure relief hole. Outside hole 711, sealing cannot be achieved.

Abstract

The invention discloses an automatic pressure relief valve and a data disaster recovery storage device comprising the same. The automatic pressure relief valve comprises a valve body, a movable part and an elastic part, wherein a pressure relief hole is formed in the valve body; the movable part is configured to be capable of moving between a first position and a second position; when the movable part is located at the first position, the pressure relief hole is closed; and when the movable part is located at the second position, the pressure relief hole is opened, and the elastic part is used for providing elastic force facing the first position for the movable part. When the temperature gradually rises, the air pressure on one side of the pressure relief hole continuously rises along with the rise of the temperature, finally the elastic force of the elastic part is overcome, a gap is formed between the movable part and the valve body, cooling liquid can be discharged in a high-temperature and high-pressure steam state, and meanwhile, the temperature and the air pressure of a hollow cavity are reduced; and when the air pressure is reduced to a certain value, the elastic part pushes the movable part back to the first position, and the pressure relief hole is closed again. The process is repeated for multiple times until the cooling liquid is completely leaked, the cooling liquid can fully absorb heat, and the heat resistance durability of the data disaster recovery storage device can be improved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to an automatic pressure relief valve and a data disaster backup storage device including the same. Background technique [0002] At present, some devices in vehicles, such as driving recorders, generally use built-in hard drives or SD cards to store vehicle data records. After an accident causes the vehicle to catch fire, crash, or fall into the water, the data memory (such as a built-in hard disk or SD card, etc.) is damaged due to poor protection, so that the driving data cannot be read, and the cause of the accident cannot be judged. Therefore, there is a data disaster recovery storage device for saving data storage. Protection against impact and falling water is relatively mature, but fire protection technology is not easy to realize under the premise of cost and volume constraints. In the data disaster recovery storage device in the prior art, the coolant utilization ef...
