Description

Technical Field

[0001] The invention relates to the field of water conservancy and flood prevention, and in particular to an adjustable flood prevention device for water conservancy projects. Background Art

[0002] With climate change and the acceleration of urbanization, the frequency and intensity of flood disasters are increasing year by year, especially in some low-lying areas and water conservancy engineering areas along rivers, and the demand for flood control facilities has become particularly urgent. Traditional flood control devices mostly use fixed walls or simple dam defense lines, but these devices have disadvantages such as complex installation, difficult adjustment, and inability to flexibly respond to changing flood threats. Therefore, how to design a flood control device with a simple structure, easy transportation, and the ability to adjust and enhance flood control effects according to different needs has become an important topic in the field of water conservancy engineering.

[0003] Among the existing flood control devices, although there are many flood control walls, water retaining boards, sandbags and other devices in use, they generally have some problems, such as limited flood control effect, inconvenient installation and disassembly, excessive weight or weak bearing capacity, poor adaptability to flood impact, etc. In addition, the use and maintenance costs of some traditional equipment are high, especially when widely deployed, there is significant economic pressure and manpower investment.

[0004] After searching by the inventor, the prior art disclosed the following contents regarding water conservancy and flood control:

[0005] 1) Publication No. CN115928656A discloses a water retaining device for flood control of water conservancy projects. In this technical application, the device comprises side retaining parts, a middle retaining part and a loose part; the side retaining parts and the middle retaining part are both placed on the riverbed; two side retaining parts are arranged, and the two side retaining parts are respectively located on both sides of the riverbed; a number of middle retaining parts are arranged according to the width of the riverbed, and a number of middle retaining parts are arranged at equal intervals along the width direction of the riverbed; a plurality of middle retaining parts are connected with the side retaining parts by plugging; the loose part is arranged at the connection between the middle retaining parts or on the upper side of the connection between the middle retaining parts and the side retaining parts by snapping; the sliding connecting plate of the present invention can adaptively adjust the extended length according to the width of the river channel, so as to meet the water retaining requirements of the river channels with different widths; and the stability of the present invention when plugged together is increased by the connection between the side retaining telescopic rod and the middle retaining telescopic rod and the connection between the middle retaining telescopic rods.

[0006] 2) Publication No. CN111827202A discloses an assembled temporary flood prevention device using water. In this technical application, the device includes a base, a baffle is fixedly connected to the side wall of the base, a connecting mechanism is provided at the upper end of the baffle, an arc plate is fixedly connected to the upper end of the baffle, a connecting block is fixedly connected to the lower end of the arc plate, the connecting block is movably connected to the connecting mechanism, a box is fixedly connected to the upper end of the base, a sealing mechanism is provided for sliding seal inside the box, a plurality of elastic mechanisms are fixedly connected between the sealing mechanism and the inner wall of the box, the left and right ends of the sealing mechanism are both slidably penetrated through the left and right end side walls of the box, the right end sliding seal of the sealing mechanism penetrates the baffle and is fixedly connected to a force plate, a buffer mechanism is fixedly connected between the force plate and the baffle, and the buffer mechanism is connected to the box. The present invention can effectively reduce the impact of water flow impact on the flood prevention device, improve the stability of the flood prevention device, and help ensure the safety of flood prevention. In addition, the flood prevention device also has a warning function.

[0007] 3) Publication No. CN114657938A discloses a flood control sandbox for water conservancy project construction with strong impact resistance. In this technical application, it includes: a flood control sandbox body; three evenly spaced anti-skid bases are fixedly installed at the lower end of the flood control sandbox body; and impact-resistant baffles are installed along the left and right side walls on the front and rear inclined side walls of the flood control sandbox body. In the present invention, the extrusion support frame moves along the slide rod, so that the support foot plate and buffer pad on the opposite side of the impacted side extend out, thereby playing the role of rear support to prevent rollover. At the same time, in the process of the pressure plate extruding the support frame, the opposite pressure plate will also contact the extrusion support frame, thereby playing the purpose of buffering and resetting, thereby improving the impact resistance, and solving the problem that the flood control sandbox is easy to move or roll over with the impact of the water flow during use, which makes it difficult to remove the internal sand. In severe cases, it is difficult to achieve the purpose of emergency rescue, which will cause the disaster to expand.

[0008] Among them, the above-mentioned prior art 1 adopts a modular design to make it more lymphatic or, but this technology contains multiple adjustable and connectable components, such as telescopic rods, connecting plates, etc., which increases the complexity of the structure and the difficulty of maintenance. In addition, under the impact of strong water flow, the loose parts and the telescopic structure may easily loosen or deform, affecting the flood prevention effect; while the prior art 2 provides sealing and buffering functions, but it mainly responds to water flow impact through sealing mechanisms and elastic elements, which may not be sufficient to cope with strong water flow in extreme cases, especially when exposed to water flow for a long time; and the prior art 3 improves the impact resistance of the sandbox through the design of inclined side walls and impact-resistant baffles, but the application scenarios of this technology are mainly concentrated in sandbox flood prevention, and the flood prevention effect of the sandbox itself may be limited, especially in the face of long-term large water flow, the sandbox may not be able to provide sufficient support.
