When the connected baffles are rotated until they are perpendicular to each other, the baffles connect and form a stepped structure, extending vertically and horizontally one after the other. In use, the baffle is formed by connecting the baffles using roller catches, and then the baffles are rotated and folded for storage, or rotated vertically and then locked for use. The devices on both sides of the roller catch are pressed to release the locking state, and the baffles are folded for storage. The roller catch is pulled along the tenon to remove the baffle set. In the installation method, the tenon and mortise are concentric arcs, with the roller catch of the connecting device serving as the center of the circle. When the tenon is rotated and pulled out of the mortise, the adjacent baffles are overlapped, and after the tenon is rotated and inserted into the mortise, the baffles are expanded so that the adjacent baffles are vertical.

[0041] Specifically, the lower vertical plate 1 is provided below the front wall ceiling of the flood control wall 7, the intermediate flat plate 2 is positioned flat on the ceiling of the flood control wall 7, and the upper vertical plate 3 is erected above the rear wall ceiling of the flood control wall 7.

[0042] The lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3 have both ends of the baffle at a 45° angle to the plate surface, with tenons 5 and mortise holes 6 provided at adjacent ends, and connecting devices 4 and roller catches provided at the ends. After adjacent baffles are connected by the connecting device 4, they can rotate around their axis, and after the tenon 5 is fully inserted into the mortise hole 6, the adjacent baffles become perpendicular to each other, the connecting device 4 and roller catches are locked in place, and the three baffles become a set after being connected.

[0043] Specifically, the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3 are each provided with assembly engagement plates 8 and engagement grooves 9 on both sides, and after multiple sets of baffle plates and grooves are joined together, they are used as water-resistant baffles in the ceiling section of the water-resistant wall 7.

[0044] Specifically, the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3 have both ends of the baffle at a 45° angle to the plate surface, and are provided with tenons 5 and mortise holes 6 respectively. After being anchored and fixed, the baffles are made into a spiral shape so that two adjacent baffles are perpendicular to each other, and the connected tenons 5 and mortise holes 6 are used to provide resistance, and the baffles are used to keep in close contact with each other under the action of water pressure to prevent water from entering.

[0045] Specifically, the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3 are equipped with connecting devices 4 and roller catches at both ends of the baffle's joints. The connecting device 4 is the axis of rotation when the baffle is assembled and rotated, and is used to prevent the tenon and mortise from getting caught. When adjacent baffles are perfectly vertical, the roller catches are locked in place and used to prevent the upper vertical plate 3 from tipping over.

[0046] Specifically, engagement plates 8 and engagement grooves 9 are provided on both sides of the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3, respectively, and are used to tightly connect the baffles horizontally and prevent water from entering.

[0047] Specifically, the lower vertical plate 1 is provided on the front lower part of the flood barrier 7, and is used to restrict the horizontal rearward movement of the baffle by being in close contact with the side of the flood barrier 7 and receiving horizontal thrust.

[0048] The intermediate plate 2 is positioned flat on the ceiling of the flood barrier 7 and is used to resist the water pressure and wave pressure acting on the upper vertical plate 3 due to the weight of the water above it, while the upper vertical plate 3 is used to prevent water in front of the wall from entering the protected area behind the wall.

[0049] Specifically, the baffle has a hollow structure.

[0050] Specifically, in the method of using the water-resistant baffle combination, the baffle is formed by connecting it using a roller catch, and the baffle is either rotated and folded for storage, or rotated until it is vertical and then locked in place to be used.

[0051] If removal is necessary, first press the devices on both sides of the roller catch to release the locking mechanism, fold and store the baffle, and then pull the roller catch along the direction of tenon 5 to remove the baffle assembly.

[0052] In the method of installing the water-resistant baffle combination, the mortise 6 and tenon 5 at the ends of the lower vertical plate 1, intermediate flat plate 2, and upper vertical plate 3 have an intermediate fit or gap fit relationship, the tenon 5 and mortise 6 are concentric arcs, and the roller catch of the connecting device 4 is at the center. When the tenon 5 is rotated and pulled out of the mortise 6, adjacent baffles are overlapped, and after rotating the tenon 5 and inserting it into the mortise 6, the baffles are unfolded to make adjacent baffles vertical and the end plate surfaces of the baffles in close contact.

[0053] Specifically, the lower vertical plate 1 is provided below the front wall ceiling of the flood barrier 7, the intermediate flat plate 2 is positioned flat on the ceiling of the flood barrier 7, and the upper vertical plate 3 is erected above the rear wall ceiling of the flood barrier 7. Both ends of the baffles, the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3, are at a 45° angle to the plate surface. Tenons 5 and mortise holes 6 are provided at both ends of the baffles. The lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3 are connected to each other by roller catches of connecting devices 4 on both ends to form a set. After deployment, the tenon 5 fully enters the mortise hole 6, and adjacent baffles become perpendicular to each other and enter the operating state. The connecting devices are locked in place, and the baffles are made into a swastika shape so that adjacent baffles are perpendicular to each other.

[0054] The sides of the baffle are provided with assembly engagement plates 8 and engagement grooves 9, respectively. After joining together the plate grooves of multiple sets of baffles, they collectively form a flood-proof baffle that can be installed on the ceiling of a flood-proof wall.

[0055] The lower vertical plate 1 is located below the front of the flood barrier and is in close contact with the flood barrier, receiving horizontal thrust and preventing the baffle from moving horizontally backward. The intermediate flat plate 2 is positioned flat on the ceiling of the flood barrier 7 and the weight of the water above it resists the water pressure and wave pressure acting on the upper vertical plate 3, preventing the baffle from tipping over. The upper vertical plate 3 is used to prevent water in front of the wall from entering the protected area behind the wall.

[0056] Three baffles are connected to form a set, which can be directly folded and stored. The tenon 5 and mortise 6 allow the tenon 5 to rotate around the roller catch within the mortise 6, enabling the lower vertical plate 1, intermediate flat plate 2, and upper vertical plate 3 to be folded when stored. When unfolded, the end plates of the two right-angled baffles overlap, and resistance is provided by the tenon and mortise, resulting in a stable operating state.

[0057] The tenon 5 and the mortise 6 are concentric arcs, and the roller catch of the connecting device 4 is at the center.

[0058] Alternatively, the tenon 5 and the mortise 6 are concentric elliptical arcs, and the roller catch of the connecting device 4 is at the center of the circle.

[0059] The tenon 5 rotates within the mortise 6, allowing the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate 3 to be folded when stored. When unfolded, the end plates of the two baffles, which are connected at a right angle, overlap to reach the ready-to-use state.

[0060] During connection and assembly, first, one set of lower vertical plates 1, intermediate flat plates 2, and upper vertical plates 3 are placed parallel to each other so that the tenons and mortises correspond to each other, the tenons are inserted into the mortises, and force is applied to engage the roller catches to complete the connection, and after inserting the tenon 5 into the mortis 6, the lower vertical plates 1 and upper vertical plates 3 are rotated so that they are connected perpendicularly to the intermediate flat plate 2, completing the assembly of one set of baffles. The first set of baffles is installed on the ceiling of the flood control wall. The second set of baffles is assembled. The second set of baffles is installed to the left or right of the first set of baffles installed on the ceiling of the flood control wall, and connected to the pre-installed baffles via the engaging plates and engaging grooves. The assembly of baffles and the joining of the ceiling of the flood control wall are continued in the left and right directions until a complete flood control structure is formed.

[0061] Specifically, depending on the combination configuration, the lower vertical plate 1 of the combined baffle is in close contact with the flood barrier 7 in front of it, receiving horizontal thrust and preventing movement to the rear horizontally. The intermediate flat plate 2 is positioned flat on the ceiling of the flood barrier 7, and the weight of the water above it resists the water pressure and wave pressure acting on the upper vertical plate, preventing the baffle from tipping over. The upper vertical plate prevents water in front of the wall from entering the protected area behind the wall. Both ends of the lower vertical plate 1, intermediate flat plate 2, and upper vertical plate are all at a 45° angle to the plate surface, and tenons 5 and mortise holes 6 are provided at both ends, respectively, so that the baffle can be made into a swastika shape so that adjacent baffles are perpendicular to each other after the baffle is deployed, the connected tenons 5 and mortise holes 6 provide resistance, and the end faces are in close contact with each other under the action of water pressure.

[0062] The first cross-section of the mortise 6 is slightly larger than the second cross-section of the tenon 5. The tenon 5 and the mortise 6 are formed by connecting concentric arcs and semi-ellipses with the roller catch of the connecting device 4 as the center. The tenon 5 can rotate within the mortise 6, and when stored, the lower vertical plate 11, the intermediate flat plate 2, and the upper vertical plate can be overlapped. When unfolded, the end plate surfaces of the two baffles connected at right angles overlap, achieving a stable state of use. Installation includes the following steps S1 to S5.

[0063] In step S1, the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate are placed parallel to each other so that the tenon 5 and the mortise 6 correspond to each other, the tenon 5 is inserted into the mortise 6, and the roller catch is engaged with force to complete the connection, and after the tenon 5 has fully entered the mortise 6, the lower vertical plate 1 and the upper vertical plate 3 are rotated so that they are connected perpendicularly to the intermediate flat plate 2, the roller catch is locked in place, and the assembly of the baffle set is completed.

[0064] In step S2, the first set of combination baffles is installed on the ceiling of the water barrier wall 7.

[0065] In step S3, the second set of lower vertical plate 1, intermediate flat plate 2, and upper vertical plate are assembled together.

[0066] In step S4, the second set of combination baffles is installed to the left or right of the first set of baffles installed on the ceiling of the water barrier wall 7, and connected to the pre-installed combination baffles via the engaging plate 8 and the engaging groove 9.

[0067] In step S5, the assembly of the baffles and the joining of the ceiling sections of the floodproof wall 7 are continued in the left and right directions until a complete floodproof structure is formed.

[0068] Specifically, both ends of the baffle are at a 45° angle to the board surface, and after being anchored and fixed with mortise and tenon joints, they are connected at a right angle and tightly fitted together.

[0069] Specifically, in step S1, the tenon 5 and the mortise 6 can only be connected and disconnected when the two baffles are overlapping in parallel.

[0070] Specifically, in step S1, after connecting with the roller catch, the tenons 5 of any two baffles can be directly rotated to fully enter the mortise holes 6, thereby completing the assembly.

[0071] Specifically, in step S1, the lower vertical plate 1, the intermediate flat plate 2, and the upper vertical plate are interchangeable during assembly, and after assembly is complete, the direction of the lower vertical plate 1 and the upper vertical plate can be reversed.

[0072] As described above, the present invention can satisfy the safety requirements for flood prevention by temporarily raising any flat embankment structure having a ceiling or vertical water surface of a flood control wall. At the same time, due to its unique shape design, the baffle structure can maintain a stable state when the water surface is located below the ceiling of the upper vertical plate. Furthermore, it has features such as a small structural cross-section, a simple structure, ease of installation and removal, and advantages in storage and transportation, thereby improving the flood control response speed and reducing flood control costs.

[0073] The above are merely preferred embodiments of the present invention. It should be made clear that those skilled in the art can make some improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered to be within the scope of protection of the present invention.
