Abstract

The present invention relates to a combination flood-proof baffle and its installation and use methods. The combination flood-proof baffle includes at least three connected baffles, with a rotating joint and a positioning guide structure between the connected baffles. Adjacent baffles are rotated from perpendicular to each other until they are tightly fitted together, and then the connected baffles are rotated in sequence to fold into a Z-shape until they are tightly fitted together. 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.

Description

[Technical Field]

[0001] The present invention relates to the technical field of flood prevention in water conservancy works, and in particular to a flood prevention combination baffle and its installation and use methods. [Background technology]

[0002] Due to the rapid development of urban construction and the impact of extreme weather, more and more regions are facing increasing pressure to improve flood control standards and protect people's lives and property, but the flood control barrier standards for river and lake embankments are unable to meet the flood control requirements. When carrying out flood control during high water periods, it is necessary not only to meet the temporary flood control requirements, but also to make construction easy and fast.

[0003] Currently, flood control materials widely use sandbags and baffle structures, but ordinary sandbags and baffle structures are large in volume, heavy in weight, and complex in structure, and are difficult to install, remove, store, and transport. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a combined flood-proof baffle that is small in volume, light in weight, and simple in structure, that can achieve its own stability by utilizing its own structural characteristics and the water pressure and water gravity on the water-inward side, that is easy to install and remove and advantageous for transportation and storage, that can be used to temporarily raise a flood barrier, and that can be applied to flat embankment structures with a critical surface that is vertical to the water-inward side, as well as methods for installing and using the same.

[0005] The present application is intended to solve one of the problems in the background art. [Means for solving the problem]

[0031] Specific embodiments of the present invention will be described in more detail below with reference to the drawings. Note that these embodiments are merely for the purpose of explaining the present invention, and the present invention is not limited to these embodiments.

[0032] In describing the present invention, it should be noted that directions or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "ceiling," "bottom," "inner," and "outer" are merely for convenience and simplification of the description of the present invention, and do not expressly or imply that the subject devices or components must have a specific orientation or be constructed or operated in a specific direction.

Those skilled in the art can interpret the specific meanings of the above terms in the present invention according to the specific circumstances.

[0034] Also, unless otherwise specified, in the description of the present invention, "plurality" means two or more than two.

[0035] As shown in Figures 1 to 3, the combined flood-proof baffle includes at least three connected baffles, with a rotating pair and a positioning guide structure provided between the connected baffles. Adjacent baffles are rotated until they are perpendicular to each other and then tightly packed together, and the connected baffles are rotated in sequence to be folded into a Z-shape and then tightly packed together. When the connected baffles are rotated until they are perpendicular to each other, the baffles are connected to form a staircase shape, extending successively in the vertical and horizontal directions.

[0036] When the present application is implemented, the flood-proof combined baffle structure of the present invention can meet temporary flood-fighting requirements, ensure flood-fighting safety, and, because of its simple structure and easy installation and removal, it can temporarily raise a wide range of flood barriers to prevent flooding during periods of flooding, greatly shortening the installation period of the flood-proof combined baffle, and at the same time, the flood-proof combined baffle is stable and can be reused many times, making storage and transportation easy. The present invention effectively overcomes various shortcomings in the prior art and has great industrial value.

[0037] Specifically, when adjacent baffles are perpendicular to each other, their end faces are tightly sealed, i.e., the connected end faces of adjacent baffles are tightly connected, and the end angles of the connected end faces of adjacent baffles are complementary to each other, and the end angles are the included angles between the ends of the baffles and the plate surface, and they are connected to each other, are perpendicular after unfolding, and are tightly connected and overlap each other after folding.

[0038] Specifically, the revolute pair includes a pin shaft and a hole to meet the needs of rotation and locking.

[0039] Specifically, the positioning guide structure includes a tenon 5 and a mortise 6, the tenon 5 and the mortise 6 are respectively provided on adjacent baffles, the tenon 5 and the mortise 6 are used for connecting the head and tail of the baffles, and the tenon 5 and the mortise 6 are used to realize guiding and position limiting.

[0040] Specifically, the baffle includes a lower vertical plate 1 , a middle flat plate 2 and an upper vertical plate 3 .

[0041] Specifically, the lower vertical plate 1 is installed below the ceiling of the front wall of the water barrier 7, the middle flat plate 2 is placed flat on the ceiling of the water barrier 7, and the upper vertical plate 3 is erected above the ceiling of the rear wall of the water barrier 7.

[0042] The lower vertical plate 1, the middle flat plate 2 and the upper vertical plate 3 have baffle ends that form a 45° angle with the plate surface, and adjacent ends are provided with tenons 5 and mortises 6, respectively, and are provided with connecting devices 4 and roller catches at the ends. After adjacent baffles are connected by the connecting devices 4, they can rotate around their own axes. After the tenons 5 are fully inserted into the mortises 6, the adjacent baffles are perpendicular to each other, and the connecting devices 4 and roller catches are locked and fixed, so that the three baffles form a set after being connected.

[0043] Specifically, engaging plates 8 and engaging grooves 9 for assembly are provided on both side edges of the lower vertical plate 1, the middle flat plate 2 and the upper vertical plate 3, and after the plates and grooves of multiple sets of baffles are joined together, they are used as flood baffles in the ceiling part of the flood barrier 7.

[0044] Specifically, the lower vertical plate 1, the middle flat plate 2 and the upper vertical plate 3 have baffles with both ends at a 45° angle to the plate surface, and tenons 5 and mortises 6 are provided respectively. After anchoring, the baffles are shaped like a swirl so that two adjacent baffles are perpendicular to each other, and the connecting tenons 5 and mortises 6 are used to provide resistance, and the baffles are tightly attached to each other under the action of water pressure to prevent water from entering.

[0045] Specifically, the lower vertical plate 1, the middle flat plate 2 and the upper vertical plate 3 are provided with connecting devices 4 and roller catches at the joints on both sides of both ends of the baffle. The connecting devices 4 are the axis of rotation when the baffle is assembled and rotated, and are used to prevent the tenons and mortises from getting caught. When the adjacent baffles are completely vertical, the roller catches are locked and fixed, preventing the upper vertical plate 3 from tipping over.

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

[0047] Specifically, the lower vertical plate 1 is provided below the front of the water barrier 7, and is used to receive horizontal thrust by being in close contact with the side of the water barrier 7, thereby restricting the horizontal rearward movement of the baffle.

[0048] The intermediate flat plate 2 is placed flat on the ceiling of the water 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, and 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 is a hollow structure.

[0050] Specifically, in the method of using the combined flood-proof baffle, the baffle is formed by connecting using a roller catch, and the baffle is rotated and folded for storage, or rotated until it is vertical and then locked and fixed for use.

[0051] When removal is required, first press the devices on both sides of the roller catch to release the locked state, fold the baffle and store it, then pull the roller catch along the direction of the tenon 5 to remove the baffle set.

[0052] In the method for installing the combined flood-control baffles, the mortises 6 and tenons 5 at the ends of the lower vertical plate 1, intermediate flat plate 2, and upper vertical plate 3 have a transition fit or clearance fit relationship, and the tenons 5 and mortises 6 are concentric arcs, with the roller catch of the connecting device 4 as the center. When the tenon 5 is rotated and pulled out of the mortise 6, the adjacent baffles are overlapped, and after the tenon 5 is rotated and inserted into the mortise 6, the baffles are unfolded so that the adjacent baffles are vertical and the end plate surfaces of the baffles are tightly attached.

[0053] Specifically, the baffles consist of a lower vertical plate 1 installed below the front wall ceiling of the flood barrier 7, an intermediate flat plate 2 placed flat on the ceiling of the flood barrier 7, and an upper vertical plate 3 erected above the rear wall ceiling of the flood barrier 7. Both ends of the lower vertical plate 1, intermediate flat plate 2 and upper vertical plate 3 form a 45° angle with the plate surface, and tenons 5 and mortises 6 are provided at both ends of the baffles. The lower vertical plate 1, intermediate flat plate 2 and upper vertical plate 3 are connected to form a set by roller catches on connecting devices 4 on both sides of the ends. After unfolding, the tenon 5 fully enters the mortise 6, causing adjacent baffles to become perpendicular to each other and enter the operating state. The connecting device is then locked and fixed, forming a swirl shape with adjacent baffles perpendicular to each other.

[0054] On both sides of the baffle, there are provided engagement plates 8 and engagement grooves 9 for assembly, and after joining together multiple sets of baffle plate grooves, they together form a floodproof baffle that can be installed on the ceiling of a flood barrier.

[0055] The lower vertical plate 1 is located below the front of the flood barrier and is in close contact with the flood barrier to receive horizontal thrust and prevent the baffle from moving horizontally backward. The intermediate flat plate 2 is placed 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 for storage. The tenon 5 and mortise 6 rotate the tenon 5 around the roller catch within the mortise 6, allowing the lower vertical plate 1, middle flat plate 2 and upper vertical plate 3 to be folded when stored. When unfolded, the end plate surfaces of the two baffles connected at right angles overlap, and the tenon and mortise provide resistance, allowing the set to be in a stable state for use.

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

[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 in the mortise hole 6, and when stored, the lower vertical plate 1, the middle flat plate 2 and the upper vertical plate 3 can be folded, and when unfolded, the end plate surfaces of the two baffles connected at right angles overlap to reach the usable state.

[0060] During assembly, first, a set of lower vertical plate 1, intermediate flat plate 2, and upper vertical plate 3 are aligned 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. After the tenons 5 enter the mortises 6, the lower vertical plate 1 and upper vertical plate 3 are rotated so that they are all vertically connected to the intermediate flat plate 2, completing the assembly of one set of baffles. The first set of combined baffles is installed on the ceiling of the flood barrier. The second set of combined baffles is then assembled. The second set of combined baffles is installed on the left or right side of the first set of baffles installed on the ceiling of the flood barrier, and connected to the previous combined baffles via the engagement plate and engagement groove. The assembly of combined baffles and the joining of the ceiling of the flood barrier continues left and right until the complete floodproof structure is formed.

[0061] Specifically, due to 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, bearing horizontal thrust and preventing it from moving horizontally backward. The middle flat plate 2 is placed flat on the ceiling of the flood barrier 7, and the weight of the water above it resists water 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. The lower vertical plate 1, middle flat plate 2, and upper vertical plate all have ends that form a 45° angle with the plate surface, and tenons 5 and mortises 6 are respectively provided at both ends. These allow the baffles to be shaped like a swirl so that adjacent baffles are perpendicular to each other after deployment. The connected tenons 5 and mortises 6 provide resistance, allowing the end faces to be 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, and the tenon 5 and mortise 6 are formed by connecting a concentric arc and a semi-ellipse with the roller catch of the connecting device 4 as their center. The tenon 5 can rotate within the mortise 6, and the lower vertical plate 11, middle flat plate 2 and upper vertical plate can be overlapped when stored, and when unfolded, the end plate surfaces of the two baffles connected at right angles overlap, reaching a stable state for use. Installation includes the following steps S1 to S5.

[0063] In step S1, a set of lower vertical plate 1, intermediate flat plate 2 and upper vertical plate are stacked parallel to each other so that the tenons 5 and mortises 6 correspond to each other, the tenon 5 is inserted into the mortise 6, and force is applied to lock the roller catch to complete the connection, and after the tenon 5 has completely entered the mortise 6, the lower vertical plate 1 and upper vertical plate 3 are rotated so that they are all connected vertically to the intermediate flat plate 2, and the roller catch is locked and fixed, completing the combination assembly of a set of baffles.

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

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

[0066] In step S4, the second set of combined baffles is installed on the left or right side of the first set of baffles installed on the ceiling of the water barrier 7, and connected to the upstream combined baffles via the engagement plate 8 and engagement tank 9.

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

[0068] Specifically, both ends of the baffle are at a 45° angle to the plate surface, and are connected at right angles after being anchored with tenons and mortises, ensuring close contact.

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

[0070] Specifically, in step S1, after connecting with the roller catch, the tenons 5 of any two baffles can be completely inserted into the mortises 6 by directly rotating them, thereby completing the assembly.

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

[0072] As described above, the present invention can meet the flood prevention safety requirements for temporarily raising the ceiling of a flood barrier or any flat embankment structure with a vertical water surface. At the same time, its unique shape design allows the baffle structure to remain stable as long as the water surface is located below the ceiling of the upper vertical plate. It also has the characteristics of a small structural cross section, a simple structure, convenient installation and removal, and advantageous storage and transportation, thereby improving the flood prevention response speed and reducing flood prevention costs.

[0073] The above is merely a preferred embodiment of the present invention, and it should be clear that those skilled in the art may make some modifications and substitutions without departing from the technical principles of the present invention, and these modifications and substitutions shall also be considered to be within the scope of protection of the present invention.
