Description

Technical Field

[0001] The utility model relates to the technical field of flood control and emergency rescue equipment, in particular to a flood control and emergency rescue device with anti-scouring ability. Background Art

[0002] A dike refers to a water retaining structure built along the edges of rivers, canals, lakes, coasts, floodways, flood diversion areas, and reclamation areas. Under the long-term action of high water levels, it is prone to emergencies. The more common ones include overtopping, seepage, slope failure, piping, bank collapse, cracks, etc. It has always been the top priority of flood control and emergency rescue and is also the key focus in the current flood disaster prevention. First, various preventive measures should be taken to avoid emergencies in the project. In case of unexpected emergencies during the flood response, emergency rescue measures need to be taken immediately to control the emergency within the smallest range and to the least extent. Thus, various rescue equipment, materials, and plans have emerged to deal with different types of emergencies.

[0003] In the prior art, when emergencies such as landslides, collapses, bank collapses, cave-ins, and even breaches occur due to dike scouring, generally measures such as filling with soil bags or sandbags, wire stone cages, and hanging willows are taken for emergency rescue. Basically, they are all traditional models and equipment, which often take a long time and consume a huge amount of manpower and material resources. If not handled properly, it is easy to cause the further expansion of the emergency and lead to serious consequences. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flood control and emergency rescue device with anti-scouring ability, so as to solve the technical problems of long time consumption and large consumption of manpower and material resources of the traditional disposal models and equipment for dike emergencies in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A flood control and emergency rescue device with anti-scouring ability provided by the utility model includes a water retaining support surface and a plurality of fixing units;

[0007] The water retaining support surface includes a plurality of support skeletons and a water retaining cloth sleeved on the plurality of support skeletons; one ends of the plurality of support skeletons are provided with fixed ends, and the other ends are respectively connected to the plurality of fixing units; adjacent fixing units are connected by connecting pieces.

[0008] The utility model can be prefabricated and assembled according to the project size. When an emergency occurs and is needed, it is transported to the site by a vehicle, and then hoisted to the corresponding position by a crane or other lifting machinery, and pulled from the compressed state to the extended state, so that the water-facing surface of the water retaining support surface is in an open state; after arranging a plurality of fixing units, adjacent fixing units are connected by connecting pieces to complete the layout of the device.

[0009] Optionally or preferably, the fixing unit includes a fixing pile and a push rod;

[0010] A limiting hole is formed in the fixing pile, and the push rod is slidably connected to the fixing pile through the limiting hole;

[0011] One end of the fixing pile is formed with a conical portion, and the other end is connected with a floating ball mechanism.

[0012] Optionally or preferably, the floating ball mechanism includes a connecting rod, a plurality of fixing rods and a floating ball;

[0013] A deep groove is formed in the fixing pile, and the connecting rod is movably connected to the inner side wall of the deep groove through a second rotating shaft; one end of the connecting rod close to the push rod is movably connected to the push rod through a first rotating shaft;

[0014] The end of the connecting rod away from the push rod is connected to the floating ball through a plurality of the fixing rods.

[0015] As the flood water rises continuously, the buoyancy force on the floating ball gradually increases at this time. The floating ball drives the connecting rod to move upward through a plurality of fixing rods. At this time, the connecting rod takes the second rotating shaft as a fulcrum and applies a downward pressure to the push rod. The push rod is tightly nailed to the ground under the action of the pressure. Therefore, as the water level rises, the fixing effect of the fixing unit can be further improved.

[0016] Optionally or preferably, an energy dissipation semi-circular plate is longitudinally arranged on the floating ball.

[0017] By providing the energy dissipation semi-circular plate, the impact of water flow on the floating ball can be reduced, thereby improving the energy dissipation effect and service life of the floating ball.

[0018] Optionally or preferably, the support skeleton is arranged in a C shape and has an opposite convex surface and concave surface;

[0019] An energy dissipation structure layer is arranged on one side of the water retaining cloth close to the concave surface of the support skeleton.

[0020] Optionally or preferably, the energy dissipation structure layer is a mesh structure layer, a porous structure layer or a bionic branch-shaped structure layer.

[0021] Optionally or preferably, the connecting piece is a telescopic rod.

[0022] Based on the above technical solutions, the utility model can at least produce the following technical effects:

[0023] (1) The flood control and emergency rescue device with anti-scouring ability provided by the utility model can be quickly deployed at the location where the danger occurs, and the effect of water retaining and energy dissipation can be effectively achieved through the water retaining support surface and a plurality of fixing units;

[0024] (2) Through the floating ball mechanism arranged within the fixed unit, on the one hand, it can consume a part of the energy when the flood water level rises; on the other hand, it can apply a downward pressure to the ejector rod through the connecting rod, so that the ejector rod is tightly nailed to the ground downward under the action of the pressure;

[0025] (3) Through the energy dissipation structure layer arranged on the concave surface of the water retaining cloth, it can further reduce the impact force of the water flow, strengthen the integrity of the emergency rescue device with the ground and the internal structure of the endangered dike, reduce the water flow from entering the interior of the dike to damage the structure, further cause damage to the dike, play a role in water retaining and energy dissipation, reduce the scouring and damage to the dike, and finally achieve the purpose of emergency rescue.

Detailed Embodiment

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment

[0033] Please refer to Figures 1 to 4, A flood control and emergency rescue device with anti - impact ability, including a water - retaining support surface 10 integrally in a C - shape and multiple fixing units 20; among them, the water - retaining support surface 10 includes multiple C - shaped support skeletons 11, and the distance between the multiple support skeletons 11 is adjustable, so that the water - retaining support surface 10 of the device can be in a deployed or compressed state; it can be understood that the support skeletons 11 make the water - retaining support surface 10 have corresponding convex surfaces (arch surfaces) and concave surfaces, and the concave surface is the water - retaining surface or the water - inlet surface.

[0034] In this embodiment, a water - retaining cloth 12 is sleeved on the support skeleton 11. The water - retaining cloth 12 is made of polyethylene, polypropylene, polyester fiber, nylon or fiberglass (belonging to the same type of material as the high - strength synthetic fiber fabric and rubber of the rubber dam bag), which can effectively achieve the effects of water - retaining and impact resistance and has strong tensile properties.

[0035] In order to prevent the water - retaining cloth 12 from shifting or loosening during use or transportation, in this embodiment, a spherical fixed end is also provided at the upper end of the support skeleton 11; the lower ends of the multiple support skeletons 11 are respectively connected to the multiple fixing units 20.

[0036] In this embodiment, the fixing unit 20 includes a fixing pile 21 and a top rod 22 arranged in the fixing pile 21; in actual work, the fixing pile 21 should be flexibly connected to the water - retaining cloth first, then the fixing pile 21 is arranged in a hole with a certain depth, and the adjacent fixing units 20 are connected through a connecting piece 30. Through the series - connected fixing piles 21, a water - retaining cloth 12 with a certain width and the foundation support surface, the fixing effect of the fixing pile 21 is realized.

[0037] Specifically, a limiting hole 23 is opened in the fixing pile 21, and the above - mentioned top rod 22 is slidably connected to the fixing pile 21 through the limiting hole 23. A conical part 24 is provided at the lower end of the top rod 22, and a floating - ball mechanism is connected to its upper end. The top rod 22 can be tightly nailed to the ground under the action of the floating - ball mechanism, further improving the fixing effect of the fixing unit 20.

[0038] In this embodiment, the floating - ball mechanism includes a connecting rod 25, multiple fixing rods 26 for fixing the floating ball 27, and the floating ball 27.

[0039] Specifically, a deep groove 210 is opened on the fixing pile 21. One end of the connecting rod 25 extends into the deep groove 210 and is movably connected to the inner side wall of the deep groove 210 through a rotating shaft two 29; one end of the connecting rod 25 close to the top rod 22 is movably connected to the top rod 22 through a rotating shaft one 28.

[0040] It can be understood that when the end of the connecting rod 25 far from the ejector rod 22 is lifted upward, the connecting rod 25 can use the second rotating shaft 29 as a fulcrum to provide a downward pressure to the ejector rod 22. At this time, the conical part 24 at the lower part of the ejector rod 22 can be tightly nailed to the ground, thereby further improving the fixing effect.

[0041] In this embodiment, when the flood water level continues to rise, the floating ball 27 can obtain an upward buoyancy force accordingly, so as to provide an upward force to the end of the connecting rod 25 far from the ejector rod 22, and then make the other end of the connecting rod 25 act on the ejector rod 22 to nail it downward tightly.

[0042] In this embodiment, a plurality of floating balls 27 can consume a part of energy when the flood water level rises; in addition, in order to reduce the impact of the water flow on the floating balls, thereby improving the energy dissipation effect and service life of the floating balls, in this embodiment, a longitudinal energy dissipation semi-lunar plate 211 is further arranged at the lower part of the floating ball 27. One end of the energy dissipation semi-lunar plate 211 is fixedly connected to the floating ball 27, and the energy dissipation semi-lunar plate 211 can be a curved plate with a certain arc.

[0043] The flowing flood has a certain kinetic energy. The greater the flood velocity, the greater its kinetic energy. After the flowing flood encounters the energy dissipation semi-lunar plate 211, it pushes the energy dissipation semi-lunar plate 211 to rise, and the flow velocity of the flood also decreases simultaneously. The kinetic energy of the flood is converted into the potential energy of the rising of the energy dissipation semi-lunar plate 211, thereby playing a first-step energy dissipation role and reducing the flood impact force. At the same time, the rising of the energy dissipation semi-lunar plate 211 also drives the ejector rod 22 to continue to be pressed downward through the connecting rod 25 and the second rotating shaft 29, and further adheres to the contact surface. The kinetic energy of the flood is also converted into a part of mechanical energy through the connecting rod 25 and the second rotating shaft 29.

[0044] In order to further improve the energy dissipation effect, in this embodiment, an energy dissipation structure layer 14 is further arranged on the concave side of the water blocking cloth 12 close to the support skeleton 11. The energy dissipation structure layer 14 can be bonded or snap-connected to the concave side of the water blocking cloth 12.

[0045] Specifically, the above-mentioned energy dissipation structure layer 14 can be a mesh structure layer, a porous structure layer or a bionic branch-shaped structure layer. Preferably, the energy dissipation structure layer 14 is a bionic branch-shaped structure layer.

[0046] A flood control and emergency rescue device with anti-scouring ability provided by the present utility model aims to solve the problems such as long time consumption, huge consumption of manpower and material resources in the processes of dike plugging, blocking and emergency rescue of dangerous works, etc., and realizes the purpose of risk disposal quickly, conveniently and relatively safely when risks such as dike gap plugging and dangerous work emergency rescue occur in the dike.

[0047] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
