The pressure plug is double-layered, and a sensing rod is fixedly provided on the lower layer of the pressure plug, and the upper layer of the pressure plug is fixedly provided on the sealing layer, so that when the air pressure in the sealed inner tank increases, the lower layer of the pressure plug is pushed to drive the sensing rod to move upward, so that the sensing rod contacts the sensor on the sensing gear to drive the sensing gear to rotate, and the sensing gear moves the lifting rack upward through the gear set, and the lifting rack is slidably installed on the fixed layer and fixedly connected to the sealing layer. When the lifting rack moves upward, it drives the sealing layer to move upward to increase the space inside the sealed inner tank to prevent accidents caused by excessive air pressure. The patent is provided with an adsorption bottle body, which greatly reduces the risk of leakage of harmful substances.

[0014] The present invention provides a leakage-proof bio-jet fuel storage device, which has the following beneficial effects:

[0015] (1) The anti-leakage bio-jet fuel storage device moves the L-shaped plate toward the storage tank body to break away from the contact with the protection groove and release the limit on the connecting rod. The L-shaped plate can prevent the sliding pipe from loosening or displacement due to external force or misoperation, thereby ensuring the stability of the connection and reducing the risk of fuel leakage. By loosening the connecting rod, the connecting rod moves downward under the elastic force of the No. 1 spring, and the connecting rod moves downward to contact the inner wall of the docking groove and restore the limit on the sliding pipe. By properly adjusting the length of the sliding pipe, stress concentration can be avoided at the connection, thereby reducing the possibility of damage to the pipeline and the connection, and further reducing the risk of fuel leakage.

[0016] (2) The anti-leakage bio-jet fuel storage device drives the arc panel to move by moving the support rod toward the sliding pipe. The movement of the arc panel drives the curved panel to move and contact the sliding pipe to protect the sliding pipe. The support of the curved panel enables the sliding pipe to obtain uniform force distribution during operation, reducing local stress concentration, thereby effectively preventing fuel leakage. The rubber block produces slow deformation so that the support rod can only be reset slowly. The support rod can only be reset slowly, so the arc panel and the curved panel can only be reset slowly. The slow reset of the curved panel can reduce sudden impact on the sliding pipe, reduce the risk of damage to the sliding pipe, and protect the overall structure of the pipeline connection.

[0017] (3) The leak-proof bio-jet fuel storage device drives the steel wire rope to move by moving the detection rod in the direction away from the slide tube. The movement of the steel wire rope causes the protection rod to move in the direction close to the solenoid valve under the elastic force of the No. 5 spring. The protection rod moves in the direction close to the solenoid valve and contacts the protection groove to limit the button, so that the button cannot be pressed when the slide tube is adjusted. By maintaining the sealing state of the solenoid valve to the tank body during the adjustment process, the risk of accidental fuel release can be reduced, thereby preventing the fluctuations generated during the adjustment process from affecting the overall sealing stability.
