A floating ball 603 with adaptive water surface height is arranged on one side of the auxiliary baffle 3. When the transmission gear 615 and the movable rack 606 are triggered externally, The auxiliary baffle 3 automatically rises with the water level rising in cooperation with the buoyancy of the floating ball 603. Two connecting pieces 601 are connected to one side of the auxiliary baffle 3 in a mirror-symmetrical manner. The bottom of the connecting piece 601 away from the auxiliary baffle 3 is connected to a connecting rod 602. One end of the connecting rod 602 away from the connecting piece 601 is connected to the top of the floating ball 603.

The moving rack 606 is slidably connected in the cavity 10. One end of the moving rack 606 is connected to the piston rod 6 17, a piston cylinder 616 is connected to one side of the inner wall of the cavity 10, a piston rod 617 is sealed and connected to the piston cylinder 616, an end of the piston cylinder 616 away from the piston rod 617 is connected to a connecting pipe 610, an end of the connecting pipe 610 away from the piston cylinder 616 extends to the outside of the cavity 10 and is connected to a pressure airbag 611, the bottom of the pressure airbag 611 is connected to the pressing plate 8, a sliding groove is provided at the end of the movable rack 606 away from the piston rod 617, a fixed slide rod 608 is slidably connected in the sliding groove, and the other end of the fixed slide rod 608 is connected to the cavity 10 is connected to one side of the inner wall, and a third spring 607 is sleeved on the outer surface of the fixed slide rod 608.

One side of the protection box 604 is connected to two water outlet pipes 605. A one-way water outlet valve is arranged inside the water outlet pipe 605.

[0046] The specific implementation method is as follows: by setting the lifting assembly 6, when the flood is higher than the protection box 604 and enters the protection box 604, the pressure airbag 611 contracts under the action of water pressure and generates high-pressure gas, and the high-pressure gas enters the piston cylinder 616 through the connecting pipe 610 and drives the piston rod 617 to move to one side, and the piston rod 617 drives the auxiliary baffle 3 to move upward by moving the rack 606, the transmission gear 615, the rotating shaft, the ball screw 612, the screw seat 614 and the connecting frame 613. At this time, the flood will also have an impact on the float 603. When pressure is generated, the float 603 can drive the auxiliary baffle 3 and the screw seat 614 to move upward through the connecting rod 602 and the connecting piece 601, and because the ball screw 612 does not have a self-locking property, the ball screw 612 and the screw seat 614 will not interfere with each other, and the screw seat 614 can drive the ball screw 612 to rotate in the reverse direction. The auxiliary baffle 3 is acted upon by the buoyancy of the buoyancy force and the water pressure drives the ball screw 612, and the auxiliary baffle 3 can be adaptively raised and lowered as the water level rises and falls, and can adaptively face the flood situation without manual supervision.

[0047] The support assembly 2 includes an adjustment airbag 209, one side of the adjustment airbag 209 is connected to a movable plate 206, the movable plate 206 is slidably connected to the inside of the cavity 10, one side of the movable plate 206 is attached to a cam 205, the center position of the cam 205 is connected to the outer surface of the rotating shaft, the side of the adjustment airbag 209 away from the movable plate 206 is connected to a fixed plate 208, both sides of the fixed plate 208 are connected to both sides of the inner wall of the cavity 10, the side of the adjustment airbag 209 away from the movable plate 206 is connected to a connecting hose 204, the other end of the connecting hose 204 passes through the fixed plate 208 and extends to the outside of the cavity 10, and the connecting hose 204 is away from the adjustment airbag 209 One end of the connecting tube 202 is connected to a connecting tube 202, and the bottom of the connecting tube 202 is connected to an adsorption plate 203 for adsorbing to the municipal road surface. Two first springs 207 are arranged between the movable plate 206 and the fixed plate 208. The two first springs 207 are distributed on both sides of the adjusting airbag 209 in a mirror-symmetrical manner. The two ends of the first spring 207 are respectively connected to one side of the movable plate 206 and one side of the fixed plate 208. Two support columns 201 are connected to one side of the main baffle 1, and one end of the support column 201 away from the main baffle 1 is hinged to the top of the connecting tube 202. One side of the adjusting airbag 209 is connected to an air outlet pipe, and a one-way valve is arranged in the connecting hose 204 and the air outlet pipe.

[0048] The specific implementation method is as follows: by setting up the support component 2, the moving rack 606 is affected by the water pressure and drives the rotating shaft and the cam 205 to rotate through the transmission gear 615. The cam 205 cooperates with the first spring 207 to drive the moving plate 206 to do reciprocating motion. The moving plate 206 drives the adjustment airbag 209 to contract and relax periodically. In conjunction with the connecting hose 204, the air outlet pipe and the one-way valve, the one-way air extraction of the connecting tube 202 can be completed, so that the pressure difference between the inside and outside of the adsorption plate 203 is increased, and the adsorption and gripping ability of the adsorption plate 203 on the municipal road surface is improved, thereby improving the support capacity of the main baffle 1 and strengthening the impact resistance of the device.

[0049] The guide buffer assembly 5 includes two side columns 501, one end of the side column 501 is connected to one side of the auxiliary baffle 3, and two sliding holes are provided at the end of the side column 501 away from the auxiliary baffle 3, in which a movable slide bar 502 is slidably connected, and a same transverse plate 506 is connected between the two groups of movable slide bars 502, and a second spring 503 is sleeved on the outer surface of the movable slide bar 502, and the two ends of the second spring 503 are respectively connected to one side of the side column 501 and one side of the transverse plate 506, and a plurality of guide wheels 505 are distributed in a linear array on one side of the transverse plate 506 away from the movable slide bar 502, and both sides of the guide wheel 505 are rotatably connected to a mounting frame 504, and one side of the mounting frame 504 is connected to one side of the transverse plate 506.

[0050] The specific implementation method is as follows: by setting a guide buffer component 5, when a flood carries larger floating objects and collides with it, the guide wheel 505 will transfer the impact force received to the second spring 503 through the transverse plate 506, and the second spring 503 will buffer and absorb the impact force, thereby reducing the damage of the support plate to the debris in the water and improving the overall protection capability of the device. At the same time, the guide wheel 505 can deflect and divert the debris in the water through its own rotation, thereby avoiding the accumulation of debris and increasing the anti-flood burden of the main baffle 1 and the auxiliary baffle 3.

[0051] Working principle: When in use, the staff moves multiple devices to the designated position, and multiple devices are connected horizontally. After that, the staff adjusts the angle of the adsorption plate 203 to make it fit closely with the municipal road surface. When floods come during the flood season, the floods put pressure on the pressure plate 8. The support column 201 and the adsorption plate 203 can effectively support the main baffle 1, and the main baffle 1 blocks the flood.

[0052] During the flood prevention process, if the flood water level rises, when the flood water level exceeds the position of the protection box 604, the flood will quickly enter the protection box 604 and quickly fill the protection box 604. At this time, the pressure airbag 611 located in the protection box 604 contracts under the action of water pressure and transmits high-pressure gas to the connecting pipe 610. The high-pressure gas enters the piston cylinder 616 through the connecting pipe 610 and drives the piston rod 617 to move to one side. The piston rod 617 drives the moving rack 606 to move to one side. The moving rack 606 drives the transmission gear 615 to rotate, the transmission gear 615 drives the rotating shaft to rotate, the rotating shaft drives the ball screw 612 to rotate, the ball screw 612 drives the screw seat 614 to move, and the screw seat 614 drives The connecting frame 613 moves, and the connecting frame 613 drives the auxiliary baffle 3 to move upward. At the same time, when the flood water level is higher than the protection box 604, the flood liquid level also exceeds the initial height of the float 603. At this time, the flood will generate pressure on the float 603, and the float 603 drives the connecting rod 602 and the connecting piece 601 to move, and the connecting piece 601 drives the auxiliary baffle 3 to move upward. The auxiliary baffle 3 drives the screw seat 614 to move through the connecting frame 613. Since the ball screw 612 does not have self-locking properties, the ball screw 612 can drive the screw seat 614 to move, and the screw seat 614 can also drive the ball screw 612 to rotate in the opposite direction. The auxiliary baffle 3 is driven by the buoyancy of the water pressure and the ball screw 612. The two cooperate with each other to drive the auxiliary baffle 3 to rise and fall with the water level.

[0053] When the flood water level rises, the pressure on the main baffle 1 will increase. At this time, the moving rack 606 is affected by the water pressure and drives the transmission gear 615 to rotate. The transmission gear 615 drives the rotating shaft to rotate. The rotating shaft drives the cam 205 to rotate. The cam 205 drives the moving plate 206 to move. At the same time, the first spring 207 drives the moving plate 206 to do a reset movement, so that the moving plate 206 does a reciprocating motion. The moving plate 206 drives the adjustment airbag 209 to contract and relax periodically. In conjunction with the connecting hose 204, the air outlet pipe and the one-way valve, the connecting tube 202 can be unidirectionally exhausted, thereby reducing the air in the adsorption plate 203, increasing the pressure difference between the inside and outside of the adsorption plate 203, and improving the adsorption and gripping ability of the adsorption plate 203 on the municipal road surface.

[0054] When in use, the entire guide buffer assembly 5 rises and falls with the rise and fall of the auxiliary baffle 3, so that the guide wheel 505 is always located near the flood liquid surface. When the flood carries larger floating objects, the floating objects will first contact the guide wheel 505, and the guide wheel 505 will transfer the impact force to the transverse plate 506. The transverse plate 506 transfers the impact force to the second spring 503, and the second spring 503 buffers and absorbs the impact force.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
