further, the support rods 31 on the upper side and the lower side are arranged in an inverted splayed manner, and the hinge rods 32 on the upper side and the lower side are arranged in a regular splayed manner, as shown in fig. 11 and 12, the stress of the baffle 21 can be effectively enhanced through the support rods 31, the hinge rods 32 and the connecting rods 34, and the deformation resistance and the pressure resistance of the baffle 21 when being impacted are enhanced, so that the protection effect of the baffle 21 is increased;

further, the buffer mechanism comprises a base 35, one end of each of the upper and lower connecting rods 34, which is far away from the hinge rod 32, is hinged to the upper and lower ends of the base 35, the base 35 is arc-shaped, a rubber pad is glued to the surface of one side of the base 35, which is close to the oil tank body 1, a movable rod 36 is vertically welded to the upper surface of the base 35, a hole is formed in the center of the connecting plate 30, the upper end of the movable rod 36 is inserted into the opening of the hole, a second spring 37 is sleeved on the movable rod 36, two ends of the second spring 37 are respectively abutted against the connecting plate 30 and the base 35, a movable groove 38 communicated with the hole in the center of the connecting plate 30 is formed in the fixed sleeve rod 29, a third spring 39 is arranged in the third spring 39, the end of the movable rod 36 penetrates through the center hole of the connecting plate 30 and is arranged in the movable groove 38, and two ends of the third spring 39 are respectively abutted against the inner wall of the movable groove 38 and the end of the movable rod 36, as shown in fig. 12, the structure is used for absorbing and relieving the impact force when the baffle 21 is impacted or scratched, so that the impact resistance of the baffle 21 is increased, and the protection effect of the baffle 21 on the oil tank body 1 is improved;

the working principle is as follows: when the device is used, the device is firstly placed on the oil tank body 1, the baffle 21 is required to be upward, the left fixing seat 2 is positioned at the center of one side of the oil tank body 1, which faces a parking space, after the two groups of fixing seats 2 are respectively positioned at the centers of two sides of the oil tank body 1, the right fixing seat 2 is firstly attached to the oil tank body 1, all the first rotating handles 7 on the right side are sequentially rotated, when the first rotating handles 7 are rotated, the first screw rods 6 are driven to rotate, the first screw sleeves 8 sleeved on the first screw rods 6 drive the sliding blocks 9 to slide in the sliding grooves 5 through the screw thread effect, the sliding blocks 9 drive the clamping plates 10 to be in position, the anti-skid rubber pads 11 on each group of the clamping plates 10 are all attached to the outer wall of the oil tank body 1 and clamped by rotating the first rotating handles 7, then the second rotating handles 14 are rotated, the second screw rods 13 are driven to rotate, and the second screw rods 13 and the second screw sleeves 15 which are sleeved can transversely move through the screw thread effect, so that the second screw 13 can push the left fixing seat 2 towards the oil tank body 1, the guide rod 17 on the oil tank body 1 can slide along the guide hole 16, the guide rod 17 can limit the rotation of the fixing seat 2, after the left fixing seat 2 is attached to the other end of the oil tank body 1, the second rotating handle 14 is rotated, so that the two groups of fixing seats 2 are matched to clamp the whole device on the oil tank body 1, and then all the first rotating handles 7 on the left side are rotated, so that the clamping plate 10 is attached to and clamped with the outer wall of the oil tank body 1;

when the baffle 21 is in the state shown in fig. 4, the baffle 21 can form a shield on the upper side of the oil tank body 1 to prevent rain and snow from directly contacting the oil tank body 1, and prevent acid rain and snow from being accumulated on the oil tank body 1 to corrode the paint surface or the surface layer of the oil tank body 1, meanwhile, when the oil tank body 1 is exposed to sunlight for a long time, the baffle 21 can also shield light to prevent the paint surface from aging and the internal air pressure and temperature from rising due to excessive insolation of the oil tank body 1, so as to prevent the internal oil from being excessively evaporated, and in addition, the hollow cavity 27 in the baffle 21 can isolate the temperature conduction of the inner side and the outer side to play a good heat insulation effect, and meanwhile, if water seepage occurs at the joint of the two groups of baffles 21, the water seepage can enter the guide groove 28 and flow out through the guide groove 28;

if the baffle 21 is not needed, the third rotating handle 23 can be rotated, the third rotating handle 23 can drive the third screw 22 to rotate, the third screw sleeve 24 sleeved on the third screw 22 drives the movable block 25 to move downwards through the screw thread action, and the two sets of transmission rods 26 on the movable block 25 oppositely open the support frames 20 on the two sets of lantern rings 19, so that the two sets of lantern rings 19 rotate, the support frame 20 on the lantern ring 19 will drive the two sets of baffles 21 to open oppositely, and the third rotating handle 23 will be rotated continuously until the two sets of baffles 21 are opened as shown in fig. 13, namely, the baffle plate 21 is in an open state, when the baffle plate 21 performs the opposite opening motion, the baffle plate 21 slides along the oil tank body 1 through the rubber wheel 33, at this time, the baffle plate 21 can shield both sides of the oil tank body 1, so as to avoid the damage of the paint surface or the surface layer of the oil tank body 1 caused by the collision of the flying stones caused by the rolling of the tires on the road to the oil tank body 1;

in addition, the baffle 21 can prevent objects such as vehicles from directly impacting the oil tank body 1 on the side surface, and can also prevent the oil tank truck from being scratched when turning, so that the oil tank body 1 is damaged, when the baffle 21 is affected by impact force such as impact, the baffle 21 can apply a force towards the oil tank body 1 to the connecting plate 30 through the fixed loop bar 29 and the supporting rod 31, meanwhile, the sleeve 202 can contract with the piston rod 201 due to the displacement of the baffle 21, the first spring 204 can be compressed, the connecting plate 30 can drive the base 35 to move towards the oil tank body 1 through the hinge rod 32 and the connecting rod 34, when the impact force is large, the base 35 can be attached to the oil tank body 1, and the movable rod 36 can move towards the movable groove 38, in the process, the two groups of connecting rods 34 can be oppositely opened, the hinge rods 32 can be oppositely opened, and the rubber wheels 33 can be attached to the oil tank body 1 to roll, meanwhile, the second spring 37 is compressed by the connecting plate 30 and the base 35 which are close to each other, the third spring 39 is movably extruded by the end of the movable rod 36 in the movable groove 38, in the process, the impact force applied to the baffle plate 21 is converted into kinetic energy, and the elastic deformation characteristics of the second spring 37 and the third spring 39 can well absorb and relieve the impact force, so that the influence caused by the impact force can be reduced, the protection performance of the baffle plate 21 on the oil tank body 1 is improved, and the oil tank body 1 is protected from collision, which is the whole working principle of the invention.
