Description

Technical Field

[0001] This utility model relates to the field of flood control emergency technology, specifically a rapid-assembly water-retaining cofferdam device for flood control emergency use. Background Technology

[0002] A flood is a hydrological phenomenon caused by natural or human factors, which results in a rapid increase in the volume of water in rivers and lakes, a sharp rise in water level, and overflow of riverbanks or dikes, causing disasters.

[0003] Flood control refers to a series of prevention, emergency response and recovery measures taken in response to flood disasters in order to protect people's lives and property and the natural environment.

[0004] Flood control is crucial in the face of natural disasters such as floods. However, some existing cofferdam devices are structurally unsuitable for rapid assembly in emergency situations, rendering them ineffective in blocking water flow during floods and posing a significant threat to people's lives and property. Furthermore, some cofferdam devices are inadequate in water diversion, allowing water to directly impact the cofferdam, easily causing damage and reducing its service life and flood control effectiveness. Therefore, those skilled in the art provide a rapid-assembly water-retaining cofferdam device for flood control emergencies to address the problems mentioned in the background. Utility Model Content

[0005] The purpose of this invention is to provide a quick-assembly water-retaining cofferdam device for flood control and emergency response, so as to solve the problems mentioned in the background art.

[0008] As a further embodiment of this utility model: the lower and upper water inlet and outlet guide plates are provided with water inlet and outlet guide plate positioning holes on both the upper and lower sides of the left and right ends.

[0009] As a further embodiment of this utility model: the top of the first layer of water-retaining cofferdam is fixedly connected to the positioning rods of the second layer of water-retaining cofferdam around its four sides, and the top center of the positioning rods of the second layer of water-retaining cofferdam is provided with positioning screw holes for the second layer of water-retaining cofferdam, and the number of positioning rods and positioning screw holes of the second layer of water-retaining cofferdam is four.

[0010] As a further improvement of this utility model: positioning rod positioning holes are provided around the top of the first layer of water-retaining cofferdam, and the number of positioning rod positioning holes is four.

[0011] As a further embodiment of this utility model: the inner wall surface of the positioning screw hole of the second layer water-retaining cofferdam is threadedly engaged with the positioning hidden screw of the second layer water-retaining cofferdam, and the number of positioning hidden screws of the second layer water-retaining cofferdam is four.

[0012] As a further improvement of this utility model: the top of the second layer of water-retaining cofferdam is fixedly connected with more layers of water-retaining cofferdam positioning rods, and the number of more layers of water-retaining cofferdam positioning rods is five.

[0013] As a further improvement of this utility model: a positioning screw hole is provided at the middle of the top of the positioning component of the first layer of water-retaining cofferdam, and the number of positioning screw holes is two.

[0014] As a further embodiment of this utility model: the inner wall surface of the positioning screw hole of the positioning component is threadedly connected to the positioning screw pin of the positioning component, and the top center of the positioning screw pin of the positioning component is fixedly connected to the positioning pin turning rod, and there are two positioning screw pins and two positioning pin turning rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. All components in this practical application must be made of corrosion-resistant materials to prevent damage from corrosion. During cofferdam assembly, the first-layer cofferdam should be placed in the designated flood control position, ensuring its bottom is tightly fitted to the ground to provide a stable foundation for subsequent installation. Insert the positioning pins of the first-layer cofferdam's positioning components into their positioning screw holes. By rotating the positioning pins and tightening the rod, the positioning pins will gradually screw into the positioning screw holes, thus inserting into the ground and securing the first-layer cofferdam in a stable position. Simultaneously, the operator will insert the positioning rod of the second-layer cofferdam into the positioning hole of the first-layer cofferdam. On the outer surface of the second-layer cofferdam positioning rod, insert the hidden positioning screw of the second-layer cofferdam into the positioning screw hole opened at the middle of the top of the positioning rod, and tighten the hidden positioning screw to make the first and second layers of cofferdams tightly connected. If the flood level is high, install the third layer of cofferdam on top of the second layer of cofferdam using more layers of cofferdam positioning rods, and then tighten the connection with the hidden positioning screw. In this way, layer by layer, the height of the cofferdam is continuously increased until the required water-blocking height is reached, thus constructing a complete cofferdam. This water-retaining cofferdam device resists flooding. It employs a connection method using positioning rods and positioning holes, secured with concealed screws, making operation simple and convenient, requiring no complex tools or specialized skills. In flood emergency situations, workers can quickly assemble each layer of the cofferdam, significantly shortening construction time and saving valuable time for flood control and disaster relief, effectively improving the speed of flood emergency response. Through the positioning rods and the tightening of concealed screws, a strong connection is formed between each layer of the water-retaining cofferdam, making the entire cofferdam device a stable, integrated structure. This structural design effectively disperses and withstands the impact of water flow. The impact force prevents the cofferdam from loosening or collapsing due to water flow; at the same time, the multi-layered stacking method allows for flexible adjustment of the cofferdam height according to the actual flood level, enhancing the device's water-blocking capacity and better meeting the needs of different flood control scenarios; the quick-assembly water-blocking cofferdam device allows each component to be disassembled and stored when not assembled, occupying less space and facilitating transportation and storage; compared with traditional large fixed cofferdams, it greatly reduces transportation costs and storage difficulties, improving resource utilization efficiency; when needed, the components can be quickly transported to the flood control site for assembly, improving the device's practicality and versatility.

[0017] 2. The operator places the lower-level inlet / outlet guide plate on the lower side of the inner wall surface of the first-level water-retaining cofferdam using the guide plate base frame. The positioning holes of the lower-level inlet / outlet guide plate should align with the penetration points on the left and right sides, slightly forward and up and down, of the first-level water-retaining cofferdam. The positioning holes of the upper-level inlet / outlet guide plate should align with the penetration points on the left and right sides, slightly forward and up and down, of the second-level water-retaining cofferdam. Then, insert and tighten the hidden positioning screws of the inlet / outlet guide plates to fix the lower and upper-level inlet / outlet guide plates to the front side of the inner surface of the first and second-level water-retaining cofferdams, respectively. During operation, the flood impacts the first-level water-retaining cofferdam... When constructing the first and second layer of cofferdams, some water flow enters the first and second layer cofferdams through the inlet and outlet guide holes, increasing their load-bearing capacity. When the flood recedes, the load-bearing water inside the first and second layer cofferdams is discharged through the inlet and outlet guide holes. Through the design of the lower and upper inlet and outlet guide plates and the inlet and outlet guide holes, the impact force of the flood can be dispersed and guided, allowing the water flow to pass through the cofferdam in an orderly manner. This reduces the direct pressure of the water flow on the front of the cofferdam, reduces the risk of the cofferdam being washed away, and greatly improves the safety and stability of the cofferdam under the impact of floods.

The number of the left assembly fixing piece 3, the right assembly fixing piece 4, and the first-layer water-retaining cofferdam positioning piece 6 are all two. The number of water-retaining cofferdam assembly fixing screw holes 5 is eight. The lower-layer and upper-layer inlet / outlet guide plates 8 and 9 are provided with inlet / outlet guide plate positioning holes 11 on the upper and lower sides of both the left and right ends.

The inner wall surface of the positioning screw holes 14 of the second-layer water-retaining cofferdam is threadedly engaged with hidden positioning screws 16. There are four hidden positioning screws 16 for the second-layer water-retaining cofferdam.The top of the second-layer cofferdam 2 is fixedly connected to five positioning rods 17 of the multiple layers of cofferdam. Two positioning screw holes 18 are provided at the center of the top of the positioning component 6 of the first-layer cofferdam. The inner wall surface of the positioning screw hole 18 is threadedly connected to a positioning pin 19. A positioning pin turning rod 20 is fixedly connected at the center of the top of the positioning pin 19. Both the positioning pin 19 and the positioning pin turning rod 20 are two in number.

[0024] The working principle of this utility model is as follows: When using this utility model, firstly, all components must be made of corrosion-resistant materials to prevent corrosion and damage. During cofferdam assembly, the first-layer water-retaining cofferdam 1 is placed at the predetermined flood control position, ensuring its bottom is tightly fitted to the ground to provide a stable foundation for subsequent installation. The positioning pin 19 of the positioning component 6 of the first-layer water-retaining cofferdam is inserted into the positioning screw hole 18. By rotating the positioning pin and tightening the rod 20, the positioning pin 19 is gradually screwed into the positioning screw hole 18, thus inserting into the ground, completing the first-layer water-retaining cofferdam 1. Securely position the dike; simultaneously, the operator inserts the positioning hole 15 of the positioning rod of the second-layer cofferdam 2 into the outer surface of the positioning rod 13 of the second-layer cofferdam of the first-layer cofferdam 1, inserts the hidden positioning screw 16 of the second-layer cofferdam into the positioning screw hole 14 of the second-layer cofferdam at the middle of the top of the positioning rod 13, and tightens the hidden positioning screw 16 of the second-layer cofferdam, so that the first-layer cofferdam 1 and the second-layer cofferdam 2 are tightly connected. If the flood level is high, a third-layer cofferdam can be installed on top of the second-layer cofferdam 2 by using more layers of cofferdam positioning rods 17. Then, the connections are tightened using concealed positioning screws. This process of layering and stacking is repeated to continuously increase the height of the cofferdam until the required water-blocking height is reached, thus constructing a complete water-blocking cofferdam device to resist flooding. Next, operators place the lower-level inlet / outlet guide plate 8 on the lower side of the inner wall surface of the first-level water-blocking cofferdam 1 using the guide plate base frame 7. The inlet / outlet guide plate positioning holes 11 of the lower-level inlet / outlet guide plate 8 coincide with the penetration points on the left and right sides, slightly forward and slightly upward on both sides of the first-level water-blocking cofferdam 1. Similarly, the inlet / outlet guide plate positioning holes 11 of the upper-level inlet / outlet guide plate 9 coincide with the penetration points on the left and right sides, slightly forward and slightly upward on both sides of the second-level water-blocking cofferdam 2. Insert the hidden positioning screws 12 of the inlet and outlet water guide plates and tighten them respectively. Fix the lower inlet and outlet water guide plate 8 and the upper inlet and outlet water guide plate 9 to the front side of the inner surface of the first water-retaining cofferdam 1 and the second water-retaining cofferdam 2 respectively. During the operation, when the flood impacts the first water-retaining cofferdam 1 and the second water-retaining cofferdam 2, some water will enter the first water-retaining cofferdam 1 and the second water-retaining cofferdam 2 through the inlet and outlet water guide holes 10, thereby increasing the load-bearing capacity of the first water-retaining cofferdam 1 and the second water-retaining cofferdam 2. When the flood recedes, the load-bearing water inside the first water-retaining cofferdam 1 and the second water-retaining cofferdam 2 will be discharged from the inlet and outlet water guide holes 10.In terms of lateral splicing, align the left and right mounting plates 3 and 4 of the adjacent first-layer and second-layer cofferdams 1 and 2, ensuring that the mounting bolt holes 5 on the left and right mounting plates 3 and 4 correspond one-to-one. Then, pass bolts through the mounting bolt holes 5 and tighten them using a wrench or other tools, or pass chains through the mounting bolt holes 5 to connect the adjacent first-layer and second-layer cofferdams 1 and 2 laterally, achieving a straight or curved connection. By repeatedly performing the longitudinal and lateral splicing steps, cofferdam devices of different lengths, curvatures, and heights can be constructed according to actual flood control needs.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
