Description

Technical Field

[0001] This invention belongs to the technical field of water-retaining dams, specifically, it relates to a floating water-retaining dam and its construction method. Background Technology

[0002] Currently, dams are used to restrict or block the flow of water in waterways and rivers. Existing dams are generally in the form of gates, which intercept waterways or rivers to achieve the purpose of stopping the flow; when it is necessary to release water downstream, the gates need to be opened. However, the opening and closing of this type of dam is relatively cumbersome, and with long-term use, the riverbed will accumulate serious silt, which will affect the opening and closing of the gates, so regular silt removal is required; moreover, this type of dam has poor adaptability and cannot be adapted to different river shapes. In order to adapt to different river shapes, commercially available PVC portable foldable dams are currently used. The principle is mainly to use the gravity of water and the impact force of the water flow to gradually inflate it, thereby blocking the flow of water. However, when the water flow is large or the water level exceeds its maximum limit, it will lead to the collapse of the entire structure, which may cause secondary disasters. Summary of the Invention

[0003] The purpose of this invention is to provide a floating dam and its construction method, which can rise and fall with the water level to adapt to water-blocking operations under different water levels and different intensities of water flow, and can adapt to different river channel shapes, making water-blocking and water-discharging operations more convenient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The floating dam of the present invention includes multiple connecting seats installed on a foundation bed. The multiple connecting seats are sequentially hinged along the longitudinal direction of the foundation bed and laterally intercept the river channel. Each connecting seat is detachably connected to a baffle plate. Each connecting seat is equipped with a vertical installation pipe, and the height of the vertical installation pipe is higher than the baffle plate. A floating airbag is movably fitted on the vertical installation pipe. Each floating airbag is connected to an inflation manifold. Inflating the floating airbag causes it to expand, causing adjacent floating airbags to gradually approach and contact each other, thus forming a floating airbag wall.

[0006] Optionally, the floating airbag includes a cylindrical airbag whose upper and lower ends are respectively connected to an upper fixed seat and a lower fixed seat. The upper fixed seat is connected to a connecting pipe, which connects the inflation chamber of the cylindrical airbag to the inflation main pipe. An upper guide seat and a lower guide seat are respectively constructed on the upper fixed seat and the lower fixed seat, and the vertical mounting pipe moves through the upper guide seat and the lower guide seat.

[0007] Furthermore, the cylindrical capsule is provided with a plurality of water-guiding holes, which penetrate the outer peripheral wall of the cylindrical capsule and are isolated from the inflation cavity of the cylindrical capsule.

[0008] Furthermore, the outer peripheral wall of the cylindrical capsule is symmetrically constructed with rubber connecting ears, and the corresponding rubber connecting ears on adjacent cylindrical capsules are connected to each other.

[0009] Alternatively, the upper end of the vertical installation pipe is connected to the horizontal main pipe, and the lower end of the vertical installation pipe is rotatably equipped with a sludge guiding and sludge clearing mechanism. The vertical installation pipe is connected to the outside through the sludge guiding and sludge clearing mechanism, and a limiting ring is fitted on the part of the vertical installation pipe located between the sludge guiding and sludge clearing mechanism and the floating airbag.

[0010] Furthermore, the silt guiding and dredging mechanism includes a silt guiding and dredging cover with the smaller diameter end facing upwards. The silt guiding and dredging cover is rotatably connected to the vertical mounting pipe. The silt guiding and dredging cover is covered with dredging holes, and multiple through holes are opened on the part of the vertical mounting pipe located inside the silt guiding and dredging cover. The end face of the limiting ring near the silt guiding and dredging cover is constructed with a conical surface with the larger diameter end facing upwards.

[0011] Alternatively, the connecting seat includes a fixed frame constructed on the seat body, the blocking plate is detachably installed on the fixed frame, the fixed frame has hinge ears on both sides, the corresponding hinge ears on adjacent fixed frames are hinged to each other, the seat body has a movable hole, and the lower end of the anchoring assembly passes through the movable hole and is anchored to the base bed.

[0012] Furthermore, the blocking plate includes a plate body, and connecting strips are respectively constructed on both sides of the plate body, and each connecting strip is detachably connected to the corresponding part of the fixing frame.

[0013] The plate can be a straight plate or an arc-shaped plate, and the plate can be a closed plate, a perforated plate or a filter plate.

[0014] Furthermore, the anchoring assembly includes an anchor bolt whose lower end is anchored to the base bed through the movable hole, the diameter of the movable hole being larger than the radial length of the anchor bolt; a stop block is fitted on the anchor bolt, the lower end face of the stop block being close to or in contact with the upper end face of the base body; a connecting nut is threaded onto the anchor bolt, and the connecting nut is tightened to the upper end of the stop block; an elastic rubber sleeve is fitted on the part of the anchor bolt located at the movable hole.

[0015] The construction method of the floating dam of the present invention includes the following steps:

[0016] S1. First, select the construction location of the river channel and fix the foundation bed horizontally on the riverbed along the river channel;

[0017] S2. Install the multiple connecting seats one by one on the base bed, and connect the multiple connecting seats together in sequence by means of hinge; adjust the hinge angle between adjacent connecting seats according to the water flow pattern and the shape of the river.

[0018] S3. Install the multiple baffles onto the corresponding connecting seats respectively; the selection principle for the baffles is:

[0019] During the non-flood season, perforated plates or filter screens are used to filter the water in the river.

[0020] During the flood season, enclosed panels are used to limit or isolate river flow.

[0021] S4. Assemble multiple floating airbags onto the vertical mounting tubes on the corresponding connecting seats. Then, connect the lower end of each vertical mounting tube to the bottom of the river channel and connect the upper end of each vertical mounting tube through the horizontal main tube. Connect each floating airbag through the inflation main tube.

[0022] S5. Inflate each floating airbag to ensure that the floating airbag floats on the water surface and can slide vertically.

[0023] S6. When the rainfall is low, the inflation degree of the floating airbags is controlled so that there is a certain gap between adjacent floating airbags, so that the water flow can be restricted through the gap; when the rainfall is high, the inflation degree of the floating airbags is controlled so that adjacent floating airbags expand and compress each other, so that all the floating airbags are in close contact to form a floating airbag wall, which is used to block the water flow.

[0024] S7. Periodically connect the sludge pump to the horizontal main pipe and use the sludge pump to remove the sludge accumulated at the floating dam.

[0025] The advantages of this invention are reflected in the following aspects:

[0026] 1. By setting the floating airbag body on the base bed connecting seat to intercept the river channel to form a floating airbag wall, its shape can be adaptively adjusted according to the river channel's own conditions or water flow conditions to limit or intercept the river channel water flow, thus playing a basic liquid level interception role.

[0027] 2. When water blocking is not required, the floating airbags are not inflated, or only a small amount of gas is inflated, so that there are gaps between the floating airbags. When the liquid level exceeds the height of the floating airbag wall, the water flows downstream through the gaps between the floating airbags.

[0028] 3. When further flow restriction is required, the inflation amount of the floating airbags can be adjusted to control the size of the gaps between the floating airbags, thereby reducing the amount of water discharged downstream.

[0029] 4. When it is necessary to block the river channel, ensure that the floating airbag floats to the high water level. Then, inflate the floating airbag so that the adjacent floating airbags come into close contact and are squeezed to form a floating airbag wall. As the lower part of the floating airbag wall expands to fit tightly against the baffle plate on the connecting seat, the floating airbag wall works with the baffle plate to block the river channel.

[0030] 5. This invention connects the vertical installation pipe to the bottom of the river channel and the horizontal main pipe to the vertical installation pipe. Therefore, the horizontal main pipe is pumped by a sludge pump to achieve the purpose of sludge removal. In this way, there is no need for personnel or sludge removal equipment to go into the water for sludge removal.

[0031] In summary, this invention utilizes floating airbags to float in water, enabling the floating airbag wall to rise and fall with the water level, thus adapting to water blocking operations under different water levels and water flow intensities, while also adapting to different river channel shapes, making water blocking and drainage operations more convenient.

Detailed Implementation

[0045] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0046] This invention discloses a floating dam, such as Figure 1-11As shown, the invention includes multiple connecting seats 200, multiple baffle plates 300, and multiple floating airbags 500. The connecting seats 200 are all mounted on the base bed 100, and are sequentially hinged and laterally intercepted in the river channel. Each baffle plate 300 is correspondingly mounted on each connecting seat 200. A vertical mounting pipe 400 is installed on each connecting seat 200, and the upper end of the vertical mounting pipe 400 is higher than the baffle plate 300. Each floating airbag 500 is movably fitted onto its corresponding vertical mounting pipe 400 and can slide up and down on it. Each floating airbag 500 is connected to an inflation manifold 800. The invention allows each floating airbag 500 to be inflated, causing them to expand and reducing the gap between adjacent floating airbags 500. This allows the floating airbags 500 to gradually approach and contact each other, forming a floating airbag wall.The working principle and advantages of this invention are as follows: After selecting an installation location on the river channel, multiple connecting seats 200 are sequentially hinged and installed on the base bed 100 at the bottom of the river channel. These connecting seats 200 are connected to form a retaining wall. This retaining wall can be appropriately adjusted in shape according to the river channel's own conditions or the water flow, enabling it to limit or intercept water flow in different river conditions. The retaining wall primarily serves to intercept the base liquid level and provides an installation foundation for the floating airbag 500. The floating airbag 500 of this invention... Each of the 00 units is installed on its corresponding connector 200, arranging all the floating airbags 500 in sequence. When water blocking is not required, the floating airbags 500 can be left uninflated or inflated with a small amount of gas, creating gaps between them. When the liquid level exceeds the aforementioned interception wall, the water flows downstream through these gaps. When further flow restriction is needed, the inflation level of the floating airbags 500 can be adjusted by varying the amount of gas inflated, thus controlling the flow. The degree of reduction in the gap between the floating airbags 500 varies, thereby reducing the amount of water discharged downstream. When it is necessary to block the river channel, the floating airbags 500 are ensured to float to a high water level. Then, the floating airbags 500 are inflated, causing them to come close together and press against each other to form a floating airbag wall. The lower part of this floating airbag wall expands to adhere tightly to the baffle plate 300 on the connecting seat 200, so that the floating airbag wall, together with the baffle plate 300, can achieve the function of blocking the river channel. Moreover, this invention can install the vertical installation pipe 4 The horizontal main pipe 700 connects to the bottom of the river channel, and the vertical installation pipe 400 is connected to the horizontal main pipe 700. The horizontal main pipe 700 is pumped by a sludge pump to achieve the purpose of sludge removal. In this way, there is no need for personnel or sludge removal equipment to go into the water for sludge removal. In summary, the present invention uses the floating airbag 500 to float in the water, so that the floating airbag 500 or floating airbag wall rises and falls with the rise and fall of the water level, thereby adapting to water blocking operations under different water levels and different intensities of water flow, and can adapt to different river channel shapes, making water blocking and drainage operations more convenient.

[0047] In a preferred embodiment of the present invention, during non-flood seasons when no water-blocking operations are required or the river channel does not need to be cut off, each floating airbag 500 can be simultaneously inflated, and then the main inflation pipe 800 can be removed. This leaves each floating airbag 500 separated and freely moving. Under the action of water flow, the floating airbags 500 will rotate, meaning the water flow continuously washes over them, preventing debris and algae from adhering to their surfaces, thus achieving cleaning of the outer surfaces of the floating airbags 500. During flood seasons, especially when rainfall is heavy, each floating airbag 500 needs to be connected to the main inflation pipe 800. This allows for simultaneous inflation of the floating airbags 500 to form a floating airbag wall without the need for wading, making the operation convenient and avoiding safety accidents caused by personnel wading through water.

[0048] As a preferred embodiment of the present invention, such as Figure 2-5 As shown, the floating airbag 500 includes a cylindrical airbag 501, an upper fixing seat 504, and a lower fixing seat 505. The upper end of the cylindrical airbag 501 is fixedly connected to the upper fixing seat 504, and the lower end of the cylindrical airbag 501 is fixedly connected to the lower fixing seat 505. The upper fixing seat 504 is connected to a connecting pipe 508, which connects the inflation chamber 502 of the cylindrical airbag 501 to the inflation manifold 800. Quick connectors can be installed at both ends of the connecting pipe 508, facilitating quick connection or disconnection between the connecting pipe 508 and the cylindrical airbag 501 and the inflation manifold 800. In this embodiment, an upper guide seat 506 and a lower guide seat 507 are respectively constructed on the upper fixing seat 504 and the lower fixing seat 505. A vertical mounting tube 400 movably passes through the upper guide seat 506 and the lower guide seat 507. By inflating the cylindrical capsule 501, it gains the ability to float. As the water level rises, the lower part of the cylindrical capsule 501 is submerged in the water, while the upper part floats above the water surface. The cylindrical capsule 501 rises and falls with the liquid level, thus limiting or obstructing the water flow.

[0049] As a preferred embodiment of the present invention, such as Figure 4As shown, the floating airbag 500 is constructed with numerous water-guiding holes 503, each penetrating the cylindrical airbag 501 and isolated from the inflation chamber 502 of the cylindrical airbag 501. In this embodiment, the water-guiding holes 503 connect the space within the inner wall of the cylindrical airbag 501 to the outside, ensuring internal and external connectivity and preventing excessive pressure. Furthermore, when the cylindrical airbag 501 is inflated to form a floating airbag wall, the water-guiding holes 503 provide a certain water-draining capacity while ensuring the stability of the floating airbag wall. When water drainage is no longer needed, the cylindrical airbag 501 continues to inflate. As the cylindrical airbag 501 gradually expands, the strength of the floating airbag wall continues to increase, while the water-guiding holes 503 gradually shrink until they close. To ensure the smooth closure of the water guide hole 503, the deformation capacity at the water guide hole 503 in the cylindrical capsule 501 is lower than that at other locations; that is, the extensibility at the water guide hole 503 is weaker. Thus, during inflation, the area surrounding the water guide hole 503 gradually encloses it. A common method is to insert a tube made of polyethylene material into the water guide hole 503, which is then fixed in place by adhesive.

[0050] In a preferred embodiment of the present invention, to improve the impact resistance of the floating airbag wall during the flood season, and to allow for the shape of the floating airbag wall to be changed as needed, such as... Figure 6 As shown, each cylindrical capsule 501 has symmetrically constructed rubber connecting ears 509 on its outer peripheral wall, and the corresponding rubber connecting ears 509 on two adjacent cylindrical capsules 501 are connected to each other. Moreover, the cylindrical capsules 501 are in a free state, that is, adjacent cylindrical capsules 501 are not connected. During the process of the cylindrical capsules 501 rotating due to the impact of water flow, the rubber connecting ears 509 can scrape away debris and algae on the outer surface of adjacent cylindrical capsules 501.

[0051] As a preferred embodiment of the present invention, such as Figure 1As shown, the upper end of each vertical mounting pipe 400 is connected to the horizontal main pipe 700, and a sludge guiding and dredging mechanism 600 is rotatably installed at the lower end of each vertical mounting pipe 400. The vertical mounting pipe 400 is connected to the outside through the sludge guiding and dredging mechanism 600. A limiting ring 401 is installed on the vertical mounting pipe 400 at the position between the sludge guiding and dredging mechanism 600 and the floating airbag body 500. This invention achieves the purpose of sludge removal by connecting the sludge pump to the horizontal main pipe 700. That is, when the sludge pump is turned on, the sludge guiding and dredging mechanism 600 sucks in the surrounding sludge and discharges it directly after passing through the vertical mounting pipe 400 and the horizontal main pipe 700, avoiding the use of dredging equipment and personnel wading through water. Moreover, the sludge guiding and dredging mechanism 600 in this embodiment can guide the sludge below the floating airbag body 500 to the periphery of the floating airbag body 500, avoiding affecting the descent of the floating airbag body 500. Furthermore, due to the setting of the limiting ring 401, the lower limit of the floating airbag 500's descent is at the position of the limiting ring 401, thus preventing the floating airbag 500 from directly contacting the silt guiding and dredging mechanism 600 and affecting the normal operation of the silt guiding and dredging mechanism 600.

[0052] As a preferred embodiment of the present invention, such as Figure 5 As shown, the sludge guiding and dredging mechanism 600 includes a conical sludge guiding and dredging cover 601. The small-diameter end of the sludge guiding and dredging cover 601 is positioned upwards. The sludge guiding and dredging cover 601 is rotatably connected to the lower part of the vertical mounting pipe 400. The sludge guiding and dredging cover 601 is covered with dredging holes. Multiple through holes 402 are provided on the vertical mounting pipe 400 within the sludge guiding and dredging cover 601. Multiple swirl blades 602 are uniformly constructed circumferentially on the outer circumferential surface of the sludge guiding and dredging cover 601. Furthermore, in this embodiment, the end face of the limiting ring 401 near the sludge guiding and dredging cover 601 is constructed as a conical surface, with the large-diameter end of the conical surface facing upwards. The working principle of this embodiment is as follows: During non-dredging periods, when the water flow in the lower part of the river channel carries silt through the silt-guiding and dredging cover 601, the special shape of the silt-guiding and dredging cover 601 disperses the water flow around it. Furthermore, the water flow impacts the vortex blades 602, causing the silt-guiding and dredging cover 601 to rotate, achieving the purpose of guiding the flow and thus driving silt and other debris into the space between the two silt-guiding and dredging covers 601, avoiding interference with the descent of the floating airbag 500. In this embodiment, the conical surface of the limiting ring 401 also helps to smoothly guide the flow with the silt-guiding and dredging cover 601. During silt dredging, air or water is first pumped into the transverse main pipe 700, causing the silt between the silt-guiding and dredging covers 601 to churn. Then, a silt pump is used for suction to remove the silt from the lower part of the floating dam.

[0053] As a preferred embodiment of the present invention, such as Figure 7As shown, the connecting seat 200 includes a seat body 201 and a fixing frame 203. The fixing frame 203 is constructed on the seat body 201, and the aforementioned baffle plate 300 is detachably installed on the fixing frame 203. Hinges 204 are respectively constructed on both sides of the fixing frame 203. Corresponding hinges 204 on adjacent fixing frames 203 are hinged together, thereby realizing the hinge between the fixing frames 203. In this embodiment, a movable hole 202 is provided on the seat body 201. The lower end of the anchoring component 900 passes through the movable hole 202 and is anchored to the base bed 100. When the connecting seat 200 is impacted by water or pulled by an adjacent connecting seat 200, the connecting seat 200 will move within a small range within its movable hole 202, thereby causing the intercepting wall formed by the connecting seat 200 to deform in real time and buffer the water flow. In this embodiment, the blocking plate 300 includes a plate body 301, with connecting strips 302 constructed on both sides of the plate body 301. Each connecting strip 302 is detachably connected to a corresponding part of the fixing frame 203. The plate body 301 can be as follows: Figure 2 The shown is a straight plate; plate 301 can also be as follows: Figure 8 The curved plate shown can be used in multiple ways, such as... Figure 9 The shapes shown are sequentially installed on consecutive connecting seats 200, meaning the curved surfaces of the curved plates face the same direction; or, as shown in the example... Figure 10 The plates, as shown, are sequentially installed on continuous connecting seats 200, with the curved surfaces of adjacent curved plates facing each other. The main purpose of these two curved plate arrangements is to increase the contact area between the water flow and the baffle plate 300. Furthermore, the water flow, after impacting the curved plates, diverges, allowing the interceptor wall to withstand multi-directional impact forces, effectively buffering the water flow and preventing the interceptor wall from bearing excessive impact force due to unidirectional impact, which could reduce its lifespan. During non-flood seasons, the plate 301 can be a perforated plate or a filter screen plate, thus filtering impurities and silt from the water flow. During flood seasons, the plate 301 is a closed plate.

[0054] As a preferred embodiment of the present invention, such as Figure 4-5As shown, the anchoring assembly 900 includes an anchor bolt 901, a stop block 903, and a connecting nut 904. The lower end of the anchor bolt 901 passes through a movable hole 202 and is anchored to the base bed 100. The diameter of the movable hole 202 is larger than the radial length of the anchor bolt 901, allowing the connecting seat 200 to move around the anchor bolt 901 within the range of the movable hole 202, achieving slight position adjustments. The stop block 903 is fitted onto the anchor bolt 901, with its lower end face close to or in contact with the upper end face of the seat 201. The stop block 903 restricts the vertical displacement of the connecting seat 200. The connecting nut 904 is threaded onto the anchor bolt 901 and tightened onto the upper end of the stop block 903 to limit its position. In this embodiment, to prevent the wall of the movable hole 202 from making hard contact with the anchor bolt 901, an elastic rubber sleeve 902 is fitted on the part of the anchor bolt 901 located in the movable hole 202.

[0055] This invention also discloses a construction method for a floating dam, comprising the following steps:

[0056] S1. First, select the construction location in the river channel;

[0057] S2. Install the connecting seats 200 one by one on the riverbed 100, and connect these connecting seats 200 together in sequence by means of hinges. Change the hinge angle between adjacent connecting seats 200 according to the water flow pattern and the shape of the river.

[0058] S3. Install multiple baffles 300 on the corresponding connecting seats 200 one by one; and during the non-flood season, the baffles 300 selected are perforated plates or filter screens to filter the water in the river; during the flood season, the baffles 300 are closed plates to limit or isolate the river.

[0059] S4. Assemble multiple floating airbags 500 onto the vertical mounting pipes 400 on the connecting seat 200. Then, connect the lower end of each vertical mounting pipe 400 to the bottom of the river channel and connect the upper end of each vertical mounting pipe 400 with a horizontal main pipe 700. Connect each floating airbag 500 with an inflation main pipe 800.

[0060] S5. Inflate each floating airbag 500 to ensure that the floating airbag 500 floats on the water surface and can slide vertically.

[0061] S6. When the rainfall is low, the inflation degree of the floating airbags 500 is controlled so that there is a certain gap between the floating airbags 500, so that the water flow can be restricted through the gap; when the rainfall is high, the inflation degree of the floating airbags 500 is controlled so that the floating airbags 500 expand and compress each other, so that all the floating airbags 500 are in close contact and form a floating airbag wall to block the water flow.

[0062] S7. Regularly connect the sludge pump to the horizontal main pipe 700 and use the sludge pump to remove the sludge accumulated at the floating dam.
