[0014] The present invention also discloses a method for using a protective device for preventing coastal erosion, which specifically comprises the following steps: When the waves are large, the waves hitting the shore will push the push plate body toward the device body, thereby driving the rack and the connecting rod to move toward the device body. The rack slides inside the device body, thereby driving the side meshing gear to rotate, thereby driving the second rotating block to rotate, and the second rotating block drives the first rotating block connected to the side rotation to rotate, thereby driving the fixed block connected to the side rotation and the lifting baffle body fixed above it to rise, thereby preventing the waves from rushing to the coast. When the waves recede, the push plate assembly will be driven to reset, and the reset spring can make the push plate assembly reset faster each time. The limit ring can limit the push plate assembly when it moves back and forth. By inserting the protective assembly into the appropriate mounting seat assembly and finally inserting it into the mounting hole, the protective assembly can be quickly installed, which saves time during installation. The first edge protective plate and the middle protective plate are connected to the sealing groove through the first sealing connecting block, and a groove for the inflation strip to pass through is left in the middle. When the connecting rod moves toward the device body, it drives the piston assembly to inflate. The air cylinder moves internally, thereby squeezing the air inside the air cylinder, thereby outputting the air into the hollow block through the connecting pipe, and finally transporting the air to the inflatable strip through the hollow block, causing it to expand due to inflation, thereby making the gaps between the first edge protection plate, the middle protection plate and the second edge protection plate tighter, thereby making the sealing between them better. The larger the waves, the tighter they fit, preventing seawater from penetrating into the interior of the device due to excessive waves, thereby avoiding erosion of the coast by seawater. When the triangular block moves toward the device body together with the pushing plate body, the triangular block will squeeze the first connecting plate as it moves, thereby driving the first connecting plate to rotate around the rotating shaft, thereby driving the second connecting plate and the squeezing block to rotate together. The protective components are synchronously squeezed by the two sets of clamping mechanisms, making the protective components fit more tightly, and the inflatable strip is synchronously inflated, so that the sealing between the protective components is better and more stable. The connecting strip is fixed above the protective component by bolts, so that the protective component becomes a whole and will not be easily moved upward due to external force, making it more stable.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by using the push plate assembly and the lifting baffle assembly, when the waves hit the device body, the push plate assembly can drive the lifting baffle body to rise, thereby preventing the waves from falling onto the shore, preventing seawater from affecting the onshore roads or the shore ecosystem; The protective components can be quickly installed on the device body through the mounting base and protective components, which reduces the construction time and avoids delays due to the long construction process. By pushing the plate body, the compression assembly and the inflation mechanism, etc., the sealing between the protective components can be improved. The larger the waves are, the stronger the sealing performance is, thus avoiding the damage of the protective device caused by the waves being too large and affecting the original environment on the coast.

A protective device for preventing coastal erosion according to claim 1, characterized in that: The device body (1) comprises a device main body (11) arranged at one end of a side surface of the push plate assembly (2), a stopper (12) is fixedly connected to one end of the side surface of the device main body (11), and a mounting hole (13) is provided at one end above the device main body (11).

11. A method for using the protective device for preventing coastal erosion according to any one of claims 1 to 10, characterized in that: The specific steps include: When the waves are large, the waves will hit the shore and push the push plate body (21) towards the device body (1), thereby driving the rack (25) and the connecting rod (23) to move towards the device body (1), and the rack (25) slides inside the device body (1), thereby driving the gear (35) meshing on the side to rotate, thereby driving the second rotating block (34) to rotate, and the second rotating block (34) drives the first rotating block (33) connected to the side rotation to rotate, thereby driving the fixed block (32) connected to the side rotation and the lifting baffle body (31) fixed thereto to rise, thereby preventing the waves from rushing to the shore. When the waves recede, the push plate assembly (2) will be reset. , and the reset spring (29) can make the push plate assembly (2) reset faster each time, and the limit ring (28) can limit the push plate assembly (2) when it moves forward and backward. By inserting the protection assembly (5) into the matching mounting seat assembly (4) and finally inserting it into the mounting hole (13), the protection assembly (5) can be quickly installed, which saves more time when installing the device. The first edge protection plate (51) and the middle protection plate (52) are connected to the sealing groove (522) through the first sealing connection block (513), and a groove is left in the middle for the inflation strip (74) to pass through. When the connecting rod (23) moves toward the device body (1), it drives the piston The component (24) moves inside the inflatable cylinder (71), thereby squeezing the air inside the inflatable cylinder (71), thereby outputting the air to the hollow block (73) through the connecting pipe (72), and finally transporting the air to the inflatable strip (74) through the hollow block (73), so that the air expands due to inflation, thereby making the gaps between the first edge protection plate (51), the middle protection plate (52) and the second edge protection plate (53) tighter, thereby making the sealing between them better, and the tighter the fit when the waves are larger, preventing seawater from penetrating into the device due to excessive waves, thereby preventing the coast from being eroded by seawater. When the triangular block (22) moves toward the device body (1) together with the push plate body (21), the gaps between the first edge protection plate (51), the middle protection plate (52) and the second edge protection plate (53) are closer, thereby making the sealing between them better, and the fit is tighter when the waves are larger, thereby preventing seawater from penetrating into the device due to excessive waves, and avoiding the erosion of the coast by seawater. When moving upward, the triangular block (22) will squeeze the first connecting plate (61) as it moves, thereby driving the first connecting plate (61) to rotate around the rotating shaft (62), thereby driving the second connecting plate (63) and the squeezing block (64) to rotate together. The two sets of pressing mechanisms are used to synchronously squeeze the protective components (5), so that the protective components (5) fit more closely together. The inflation strip (74) is inflated synchronously, so that the sealing performance between the protective components (5) is better and more stable. The connecting strip (8) is fixed to the top of the protective component (5) by the bolt (9), so that the protective component (5) becomes a whole and will not be easily moved upward due to external force, making it more stable.
