DETAILED DESCRIPTION
[0014] The automobile flood prevention system of the present invention is described in detail below with reference to the accompanying drawings. Example 1
[0015] like Figure 1 , Figure 5 and Figure 7 As shown, it includes: four support systems, each support system includes: a track 1, a top rod chain 2, a corner channel 3, a hydraulic cylinder 4 and a stepping motor 5, wherein the track 1 is a cylindrical tube body, a strip opening 1-1 is formed on the side wall of the cylindrical tube body along its length direction, the length direction of the strip opening 1-1 is the same as the length direction of the track 1, and an internal thread is formed on the inner wall of the cylindrical tube body; like Figures 2~4 As shown, the top rod chain 2 is composed of a plurality of blocks 2-2 connected in series, each block 2-2 includes: a first raised plate 2-2-1, a body 2-2-2 and a second raised plate 2-2-3, the first raised plate 2-2-1 is vertically connected to the top surface of the body 2-2-2, the second raised plate 2-2-3 is vertically connected to the bottom surface of the body 2-2-2, the plane where the first raised plate 2-2-1 is located is perpendicular to the plane where the second raised plate 2-2-3 is located, a first through groove 2-2-4 is formed on the top surface of the body 2-2-2, a second through groove 2-2-5 is formed on the bottom surface of the body 2-2-2, the second raised plate 2-2-3 and the first through groove 2- The shapes of the first protruding plate 2-2-1 and the second through groove 2-2-5 are suitable, so that any two connected blocks 2-2 are connected end to end, (when the top rod chain 2 is in a compressed state) the first protruding plate 2-2-1 of each block 2-2 is located in the second through groove 2-2-5 of the block 2-2 connected to the top thereof (the block 2-2), and the second protruding plate 2-2-3 of each block 2-2 is located in the first through groove 2-2-4 of the block 2-2 connected to the bottom thereof (the block 2-2), a first opening 2-2-6 is formed on the first protruding plate 2-2-1, and a second opening 2-2-7 is formed on the second protruding plate 2-2-3; When the top rod chain 2 is lengthened, the second raised plate 2-2-3 of the block 2-2 moves out from the first through slot 2-2-4 and passes through the first opening 2-2-6 of the block 2-2 connected to the tail of the block 2-2, the first raised plate 2-2-1 corresponding to the first opening 2-2-6 (i.e. the part of the first raised plate 2-2-1 having the same height as the first opening 2-2-6) moves out from the second through slot 2-2-5, the part of the first raised plate 2-2-1 above the first opening 2-2-6 passes through the second opening 2-2-7 of the block 2-2 connected to the top of the block 2-2, the remaining part of the first raised plate 2-2-1 passing through the second opening 2-2-7 is located in the second through slot 2-2-5, so that when the top rod chain 2 is lengthened, the top rod chain 2 can only rotate along the plane where the first raised plate 2-2-1 is located; The track 1 is horizontally arranged and fixedly mounted under the main beam 6 of the automobile, the corner channel 3 is fixedly mounted under the main beam 6 of the automobile, a cavity is formed in the corner channel 3, an inlet 3-1 and an outlet 3-2 are formed on the cavity, one end of the track 1 is connected to the inlet 3-1, the plane where the outlet 3-2 is located is horizontally arranged, an inclined surface 3-3 is formed between the inlet 3-1 and the outlet 3-2, the top rod chain 2 passes through the corner channel 3 through the inlet 3-1 and the outlet 3-2, and the length of the inclined surface in the direction where the top rod chain 2 passes through the corner channel 3 is the same as the length of a body 2-2-2; The head end of the top rod chain 2 is located in the cylindrical tube body, and the tail end of the top rod chain 2 is vertically downward as a support end; the first raised plate 2-2-1 of the top rod chain 2 located in the track 1 is perpendicular to the horizontal plane.
[0016] like Figure 5 As shown, the hydraulic cylinder 4 is vertically arranged and the cylinder barrel 4-1 of the hydraulic cylinder 4 is fixedly mounted on the main beam 6 of the automobile, the piston rod 4-2 of the cylinder barrel 4-1 extends out of the hole downward, the lower part of the piston rod 4-2 of the hydraulic cylinder 4 extends out from the cylinder barrel 4-1, and at least one fixing member 7 is fixedly mounted on the piston rod 4-2. Figure 6 As shown, a through hole 7-1 is formed in the fixing member 7, and two semicircular ring-shaped clamps 7-2 are installed in the through hole 7-1, and the two semicircular ring-shaped clamps 7-2 are arranged opposite to each other; The body 2-2-2 is cylindrical and has an annular groove 2-2-8 formed along the circumference of the body 2-2-2; Each semicircular ring clamp 7-2 is installed in the through hole 7-1 through a telescopic device 7-3, so that after the telescopic device 7-3 is extended, the two semicircular ring clamps 7-2 are in contact and form a circular clamp, and the circular clamp is embedded in the annular groove 2-2-8 with the same height as the circular clamp; The head end of the top bar chain 2 is connected to a circular piece 2-1 through a bearing. The circular piece 2-1 is formed with an external thread and is threadedly connected to the inner wall of the cylindrical tube. The stepper motor 5 is used to drive the circular piece 2-1 to rotate. The stepper motor 5 is located outside the track 1 and is fixed to the block at the head end of the top bar chain 2 through the strip opening 1-1. The stepper motor 5 can indirectly drive the circular piece 2-1 to rotate through a chain or a belt. Figure 7 shown.
[0017] When the car is not flooded, the piston rod 4-2 of the hydraulic cylinder 4 extends a small distance from the cylinder barrel 4-1, which does not affect the normal driving of the car. The telescopic device 7-3 remains in the extended state, controlling the two semicircular ring clamps 7-2 to contact and form a circular clamp, and the circular clamp is embedded in the annular groove 2-2-8 with the same height as the circular clamp. When the water level reaches a dangerous height, the stepper motor 5 drives the circular member 2-1 to rotate. Since the circular member 2-1 is threadedly connected to the inner wall of the cylindrical tube, the circular member 2-1 rotates and the top rod chain 2 connected to the circular member 2-1 moves in the track 1, and the tail end of the top rod chain 2 moves vertically downward. At the same time, the piston rod of the hydraulic cylinder 4 moves downward.
[0018] Under the push of the circular member 2-1 and the pulling action of the circular clamp in the fixing member 7, the height of the support end of the top rod chain 2 gradually decreases until it touches the ground. After the support end of the top rod chain 2 touches the ground, the top rod chain 2 in the vertical direction will bear the gravity of the car. At this time, the first protruding plate 2-2-1 of the block 2-2 in the top rod chain 2 in the vertical direction enters the second through groove 2-2-5 of the block 2-2 connected to the top of the block, and the second protruding plate 2-2-3 of the block 2-2 enters the first through groove 2-2-4 of the block 2-2 connected to the bottom of the block. The connected blocks 2-2 in the vertical direction are compressed, and the top rod chain 2 in the vertical direction is transformed into a structure similar to a metal rod, which can withstand a large shear force from the side and ensure the stability of the support. The top rod chains 2 of the four support systems lift the car steadily to increase the height between the car and the ground. When the area where the car is located is out of danger, the above scheme runs in reverse to put the car back on the ground. Example 2
[0019] On the basis of Example 1, Figure 3 As shown, the second raised plate 2-2-3 includes: two rectangular plate bodies 2-2-3-1 and a cylindrical column 2-2-3-2, a rectangular plate body 2-2-3-1 is fixed at each end of the cylindrical column 2-2-3-2, the two rectangular plate bodies 2-2-3-1 are located on the same plane, and the cylindrical column 2-2-3-2 is opposite to the second opening 2-2-7. The design of the cylindrical column 2-2-3-2 in the second raised plate 2-2-3 can make the top rod chain 2 better fit with the inclined surface 3-3 when passing through the corner channel 3, that is, better realize the rotation of the top rod chain 2 along the plane where the first raised plate 2-2-1 is located. Example 3
[0020] On the basis of Example 2, the hydraulic cylinder 4 is a double-stroke hydraulic cylinder (in the same direction). There are two fixing members 7, and one fixing member 7 is fixed on each of the two piston rods of the double-stroke hydraulic cylinder. The fixing members 7 of the two piston rods of the double-stroke hydraulic cylinder can not only apply tension to the top rod chain 2 at the same time, but also apply tension to the top rod chain 2 alternately.
[0021] The telescopic device 7-3 is a tightening hydraulic device.
[0022] The angle between the inclined surface 3-3 and the vertical direction is 45°.
[0023] The automobile flood prevention system also includes: a water level detection sensor and a controller. The water level detection sensor is installed on the automobile and is used to detect the water level. The controller is electrically connected to the water level detection sensor, the stepper motor 5 and the hydraulic cylinder 4 respectively. The controller reads the data of the water level detection sensor. When the data of the water level detection sensor reaches the water level threshold, the controller controls the stepper motor 5 and the hydraulic cylinder 4 to operate.
[0024] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
