[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-Figure 4 As shown, an explosion-proof diesel refueling device includes a base 1, a plurality of support blocks are fixedly connected to the bottom surface of the base 1, a skid-mounted explosion-proof box 2 is installed on the bottom surface of the base 1, an oil storage tank 3 is arranged inside the skid-mounted explosion-proof box 2, the top of the oil storage tank 3 is connected to a refueling port extending to the outside of the skid-mounted explosion-proof box 2, a refueling machine 5 and an emergency refueling mechanism are installed on the front of the skid-mounted explosion-proof box 2, and the refueling machine 5 and the emergency refueling mechanism are connected to the oil storage tank 3 through an oil pipeline.

[0024] Two support plates 4 are installed on the inner bottom surface of the skid-mounted explosion-proof box 2 , and the oil storage tank 3 is fixedly connected to the top of the two support plates 4 .

[0025] The emergency refueling mechanism includes an outer shell 6, the inner bottom surface of the outer shell 6 is fixedly connected to an oil tank 7, the inner wall of the oil tank 7 is sealingly and slidably connected to a piston 8, the top surface of the piston 8 is fixedly connected to a piston rod 9, and one end of the piston rod 9 extending to the outside of the oil tank 7 is fixedly connected to a resistance plate 10, and both sides of the resistance plate 10 are in sliding contact with the inner wall of the outer shell 6.

[0026] The emergency refueling mechanism also includes a rotating rod 11, which is rotatably connected between the inner walls of the outer shell 6, and a cam 12 is fixedly connected to the outer wall of the rotating rod 11.

[0027] A return spring is provided on the outer sleeve of the piston rod 9, and the return spring is located between the resistance plate 10 and the oil tank 7. By rotating the rotating rod 11 by the hand wheel, the cam 12 rotates accordingly, further resisting the resistance plate 10 to move downward, and the piston rod 9 moves downward accordingly, driving the piston 8 to move downward, and the diesel inside the oil tank 7 is pressed out through the oil gun. Then the return spring makes the resistance plate 10 move up and back to its original position, and the diesel in the oil storage tank 3 is pumped into the oil tank 7.

[0030] Working principle: Before using this explosion-proof diesel refueling device, first check whether this explosion-proof diesel refueling device can be used normally. When the refueling machine 5 cannot be used normally, the emergency refueling mechanism can be used for refueling. Just rotate the rotating rod 11 through the hand wheel, and the cam 12 will rotate accordingly, further resisting the downward movement of the resistance plate 10, and the piston rod 9 will move downward accordingly, driving the piston 8 to move downward, and the diesel in the oil tank 7 will be pressed out through the oil gun. Then the reset spring will move the resistance plate 10 back to its original position, and the diesel in the oil storage tank 3 will be pumped into the oil tank 7. Repeat the above operation to achieve manual refueling.
