Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a flood prevention device. Background Art

[0002] Flood disasters occur all the time and the losses they cause are incalculable. In order to mitigate the disasters, there are many types of flood barriers, from traditional sandbags and earth and rocks to movable flood barriers made of steel or glass, to resist floods and protect people, property and farmland in riverside areas.

[0003] For example, the Chinese patent "CN110029625B" discloses a "detachable and easy-to-store flood control device". When the device is needed, the buried part of the flood control foundation is buried under the ground, so that the extension part is located under the ground, and the extension part is set on the side away from the flood. When subjected to the force of the flood, the flood control foundation will tend to deviate toward the side away from the flood. Under the action of the extension part, the force of the flood can be effectively resisted, and the flood control foundation can be prevented from deviating significantly toward the side away from the flood. Then the baffle and the flood control foundation are connected together. In order to keep the relative position of the baffle and the flood control foundation stable when subjected to lateral force, a support assembly of a specific shape is used to fix the relative position between the baffle and the flood control foundation, and the detachable connection method can quickly realize the disassembly operation of the baffle and the flood control foundation.

[0004] After the above search and understanding of the existing devices, it is learned that although the above-mentioned flood control device only needs to remove the supporting components when it is not needed, leaving the flood control foundation for use as a sidewalk, the supporting components still need to be manually transported to a designated storage location for storage. During the flood season, the supporting components need to be quickly built up. The supporting components must be transported, moved, and disassembled and assembled over long distances each time, which not only affects the efficiency of flood control construction, but also is inevitably damaged due to violent loading and unloading and transportation vibration during the transportation and handling of the supporting components, thereby affecting the service life. Summary of the invention

[0005] In view of the deficiencies existing in the prior art, the present invention provides a flood prevention device, which solves the problem that the flood prevention devices in the prior art have to carry out long-distance transportation, handling and disassembly and assembly of the supporting components every time, which not only affects the construction efficiency of the flood prevention, but also the supporting components will inevitably be damaged due to violent loading and unloading and transportation vibration during transportation and handling, thereby affecting the service life.

[0006] According to an embodiment of the present invention, a flood prevention device includes:

[0007] The water storage tank is provided with two columns correspondingly;

[0008] The embankment plate has mounting shafts on both sides. The embankment plate is rotatably arranged between the two columns through the two mounting shafts. A connecting block is arranged around the mounting shaft. The connecting block and the inner side of the column are both provided with mounting rods. A tension spring is rotatably arranged between the two mounting rods.

[0009] A floating plate is slidably arranged on the water storage tank, and top frames are arranged at both ends of the floating plate;

[0010] Among them, the connecting block has a first quadrant position and a second quadrant position. When the floating plate drives the top frame to squeeze the embankment plate under the action of buoyancy, the installation shaft drives the connecting block to move from the second quadrant position to the first quadrant position, and under the tension of the tension spring, the embankment plate moves between the two columns to form a flood protection surface for flood prevention.

[0011] Preferably, the embankment plate comprises a prefabricated plate connected to the installation shaft, one end of the prefabricated plate away from the installation shaft extends outward to form an interception plate, and the interception plate is provided with a plurality of interception holes.

[0012] Preferably, the prefabricated plate is recessed inwardly to form a groove, and a plurality of reinforcing ribs are arranged at intervals in the groove.

[0013] Preferably, both ends of the floating plate are provided with sliding seats, the water storage tank is provided with a sliding groove, the sliding seat is slidably engaged in the sliding groove, and pulleys are provided on both sides of the sliding seat.

[0014] Preferably, the distance between the two pulleys is smaller than the width of the slide groove.

[0015] Preferably, two sides of the water storage tank are bent outward to form installation edges, and a plurality of installation holes are provided on both installation edges.

[0016] Preferably, a plurality of connecting ribs are provided at the bottom of the column, and the plurality of connecting ribs are all connected to the top of the water storage tank.

[0017] Preferably, the sides of the two columns are provided with limiting edges, and when the embankment plate is located between the two columns, the embankment plate abuts against the two limiting edges.

[0018] Preferably, both limiting edges are provided with sealing grooves, and a sealing layer is provided in the sealing grooves.

[0019] Preferably, a drain pipe is provided on the side of the water storage tank, and the drain pipe runs through the interior of the water storage tank.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this solution, the embankment, the water storage tank and the columns are combined into one. When a flood occurs and the water level gradually rises, the water flows into the water storage tank and drives the floating plate to move with the water surface through the action of buoyancy until the top frame of the floating plate contacts the embankment and applies upward pressure to the embankment, so that the embankment rotates around the installation axis. When the connecting block of the installation axis moves from the second quadrant position to the first quadrant position, the direction of the tension generated by the tension spring changes, thereby driving the connecting block to move downward in the first quadrant position and driving the installation axis to rotate, thereby automatically moving the embankment between the two columns to form a flood control surface for blocking the flood. No human intervention is required, and it can respond quickly to sudden floods. After the flood, the embankment can be flipped back so that the connecting block moves from the first quadrant position to the second quadrant position, allowing the embankment to be re-fastened on the water storage tank. No handling and installation are required, avoiding the common transportation, loading and unloading steps in traditional flood control facilities, reducing labor costs, and reducing the risks and errors that may be caused by manual operation.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figures 1 to 8 As shown, an embodiment of the present invention provides a flood prevention device, comprising:

[0033] The water storage tank 1 is provided with two columns 2;

[0034] The embankment plate 3 is provided with mounting shafts 5 on both sides. The embankment plate 3 is rotatably arranged between the two columns 2 through the two mounting shafts 5. A connecting block 501 is arranged around the mounting shaft 5. The inner sides of the connecting block 501 and the columns 2 are both provided with mounting rods 502. A tension spring 6 is rotatably arranged between the two mounting rods 502.

[0035] The floating plate 4 is slidably disposed on the water storage tank 1, and both ends of the floating plate 4 are provided with a top frame 401;

[0036] Among them, the connecting block 501 has a first quadrant position and a second quadrant position. When the floating plate 4 drives the top frame 401 to squeeze the embankment plate 3 under the action of buoyancy, the installation shaft 5 drives the connecting block 501 to move from the second quadrant position to the first quadrant position, and under the tension of the tension spring 6, the embankment plate 3 moves between the two columns 2 to form a flood protection surface for flood prevention.

[0037] In the embodiment of the present invention, as a flood prevention facility, when the present solution is applied to a canal bank, a river bank or a dike, firstly, a pit at the height of the water storage tank 1 is constructed on the canal bank, the river bank or a designated installation position, and the water storage tank 1 is fixedly installed in the construction position. When no flood occurs, the dike plate 3 is always buckled at the mouth of the water storage tank 1, and a guardrail can be installed between the two columns 2, which ensures the safety of pedestrians while not affecting the appearance. Figure 8, the connecting block 501 is divided into the first quadrant and the second quadrant under the drive of the installation shaft 5. When there is no flood, the connecting block 501 is located on the left side, that is, the second quadrant, symbol B area, with the marked line A as the reference, symbol C is the first quadrant. When the water level of the channel, river or dam gradually rises, the water flows into the water storage tank 1, and the floating plate 4 is driven by the buoyancy to follow the water surface until the top frame 401 of the floating plate 4 contacts the embankment plate 3. While the water level continues to rise, the top frame 401 squeezes the embankment plate 3 upward, so that the embankment plate 3 moves upward and drives the installation shaft 5 to rotate. During the rotation of the installation shaft 5, when the connecting block 501 exceeds the marked line A, the direction of the tension of the tension spring 6 on the connecting block 501 is changed, that is, it is pulled to the right and downward, so that the connecting block 501 moves downward and drives the installation shaft 5 to rotate clockwise, so that the embankment plate 3 rotates around the installation shaft 5, and automatically moves the embankment plate 3 between the two columns 2 to form a flood protection surface for blocking floods. No human intervention is required, and it can respond quickly to sudden floods. When the flood recedes, the maintenance personnel drain, clean, and inspect the water tank 1, embankment plate 3 and other components, and flip the embankment plate 3 back, so that the connecting block 501 moves from the first quadrant position to the second quadrant position. The connecting block 501 is pulled leftward and downward by the tension spring 6, and is re-fastened in the water tank 1 under the gravity of the embankment plate 3 itself. No handling and installation are required, which avoids the common transportation, loading and unloading steps in traditional flood control facilities, reduces labor costs, and reduces the risks and errors that may be caused by manual operation.

[0038] When used in batches, see Figure 3 , pits can be constructed along the length of the canal bank, river bank or embankment, and this solution can be installed and spliced ​​one by one. It is not limited to the canal bank, river bank or embankment. For example, at each entrance and exit, pits are constructed at the designated positions of the entrance and exit, and the water storage tank 1 is installed to the pit, so that the columns 2 are located on both sides of the entrance and exit walls. When the embankment board 3 is buckled with the water storage tank 1, it will not affect normal walking and driving. When a flood occurs, the entrance and exit can be closed under the action of the embankment board 3 to block the flood outside the entrance and exit.

[0039] Specifically, Figure 4 As shown, the embankment plate 3 includes a prefabricated plate 301 connected to the installation shaft 5. One end of the prefabricated plate 301 away from the installation shaft 5 extends outward to form an interception plate 302. The interception plate 302 is provided with a plurality of interception holes 303.

[0040] The prefabricated plate 301 is connected to the installation shaft 5. When the installation shaft 5 rotates, the prefabricated plate 301 is driven to move, serving as the main body of the flood barrier. At the same time, the prefabricated plate 301 can be made of a prefabricated foam board, which is light in weight and has a certain strength. Moreover, the length of the prefabricated plate 301 is smaller than the length of the mouth of the water tank 1, so that when the prefabricated plate 301 is snapped into the mouth of the water tank 1, there is still a certain distance between the end of the prefabricated plate 301 and the inner side of the water tank 1, which is used to allow water to flow into the water tank 1, and the interception plate 302 just makes up the distance between the end of the prefabricated plate 301 and the inner side of the water tank 1. The water flows into the water tank 1 through the several interception holes 303 of the interception plate 302, and the external impurities are intercepted by the several interception holes 303 to avoid entering the water tank 1 and causing obstruction.

[0041] Secondly, if Figure 4 As shown, the prefabricated plate 301 is recessed inward to form a groove, and a plurality of reinforcing ribs 304 are provided at intervals in the groove. The plurality of reinforcing ribs 304 can significantly increase the bending resistance of the prefabricated plate 301, making the entire embankment plate 3 more solid. At the same time, the inward recess of the prefabricated plate 301 can reduce the thickness of the prefabricated plate 301 and reduce the weight of the prefabricated plate 301. With the support of the reinforcing ribs 304, it helps to reduce the use of materials while ensuring sufficient strength.

[0042] Specifically, Figure 5 As shown, both ends of the floating plate 4 are provided with a slide seat 402, the water storage tank 1 is provided with a slide slot 101, the slide seat 402 is slidably engaged with the slide slot 101, and pulleys 403 are provided on both sides of the slide seat 402; with the cooperation of the slide seat 402 and the slide slot 101, it can ensure that the floating plate 4 moves up and down along the predetermined path, avoiding the floating plate 4 from deflecting or tilting during the floating process, ensuring that it can accurately trigger the top frame 401, so that the embankment plate 3 can be smoothly rotated into place, and at the same time, under the action of the pulley 403, the friction of the floating plate 4 when moving in the slide slot 101 is greatly reduced, so that the floating plate 4 can rise or fall smoothly under the action of a smaller buoyancy, allowing the floating plate 4 to flexibly adjust its position according to the actual water level changes, whether it is at a lower water level or a higher water level, it can maintain a good working condition to ensure the effectiveness of the flood control surface.

[0043] At the same time, if Figure 4 and Figure 5 As shown, the distance between the two pulleys 403 is smaller than the width of the slide groove 101; since the distance between the pulleys 403 is smaller than the width of the slide groove 101, it is ensured that the pulley 403 can roll freely in the slide groove 101 without getting stuck or obstructed, and even if there are slight unevenness or debris inside the slide groove 101, the pulley 403 can pass smoothly.

[0044] Specifically, Figure 4As shown, both sides of the water tank 1 are bent outward to form mounting edges 102, and both mounting edges 102 are provided with a number of mounting holes 103; the mounting edges 102 form a mounting structure of the water tank 1, and bolts are passed through the mounting holes 103 of the mounting edges 102 and driven into the ground, so that the water tank 1 can be firmly fixed to the ground, and the water tank 1 can be easily disassembled or repositioned when necessary, which simplifies maintenance and repair work, and the fixing and installation method is not limited to bolts, but can also be fasteners such as expansion screws.

[0045] Specifically, Figure 2 As shown, a plurality of connecting ribs 201 are provided at the bottom of the column 2, and the plurality of connecting ribs 201 are connected to the top of the water storage tank 1; the column 2 and the water storage tank 1 can be firmly combined together through the plurality of connecting ribs 201 to form a more stable structure, which can improve the structural stability of the column 2 when impacted by floods and make it less likely to deform.

[0046] Specifically, Figure 6 As shown, the sides of the two columns 2 are provided with limiting edges 202. When the embankment plate 3 is located between the two columns 2, the embankment plate 3 abuts against the two limiting edges 202. The limiting edges 202 ensure that the embankment plate 3 can be accurately docked at the predetermined position after being rotated into place, thereby avoiding excessive deflection, and there is no need to set more limiting structures at the position of the mounting shaft 5. At the same time, the two limiting edges 202 are provided with sealing grooves, and a sealing layer 203 is provided in the sealing grooves. The sealing layer 203 can effectively prevent water from penetrating from the gap between the embankment plate 3 and the column 2, thereby ensuring the integrity of the flood barrier. Even under high water pressure conditions, the sealing layer 203 can provide a reliable waterproof effect to prevent floods from penetrating through tiny gaps.

[0047] Specifically, Figure 4 As shown, a drain pipe 7 is provided on the side of the water storage tank 1, and the drain pipe 7 runs through the inside of the water storage tank 1; during use, the drain pipe 7 can be connected to the outside, or the discharge volume of the drain pipe 7 can be controlled. When it rains normally, rainwater entering the water storage tank 1 can be discharged normally through the drain pipe 7 to avoid mis-triggering the dike 3. When a flood occurs, the amount of water entering the water storage tank 1 greatly exceeds the discharge volume of the drain pipe 7, and the dike 3 can be triggered normally. At the same time, after the flood recedes, the inside of the water storage tank 1 and various components can be cleaned and discharged through the drain pipe 7 after cleaning.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
