Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a water-blocking device for flood control in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals. During the plum rain season or rainy season, sandbags are often used for temporary flood control. Sandbags are stacked to form flood walls, but sandbags are easily washed away and the effect is generally not good.

[0003] Chinese invention patent CN119711407B proposes a "flood control barrier with a two-stage compression structure". This device solves the problem that after the barrier is hit by flood, the force is uneven in different parts, which can easily lead to local seepage and leakage in the fully installed barrier. However, the device cannot drain water in time during floods, which makes it impossible to reduce the pressure on the flood control mechanism. This results in poor stability of the flood control mechanism during use, thus posing certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a water-blocking device for flood control in water conservancy projects.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] To address the technical problem that existing flood control mechanisms cannot release water in a timely manner, resulting in insufficient pressure on the mechanism, poor stability during use, and potential safety hazards, this invention provides a water-blocking device for flood control in water conservancy projects. This device enables timely water release when the water level reaches a certain height, keeping the water level within a safe range and enhancing the stability of the entire flood control mechanism during use.

[0029] It should be noted that the water-blocking equipment for flood control in water conservancy projects described in this invention is used in, but not limited to, the field of flood control. For ease of explanation, this invention only uses the application of the water-blocking equipment for flood control in water conservancy projects in the field of flood control as an example. The principle of the water-blocking equipment for flood control in water conservancy projects applied to other types of equipment is essentially the same as that applied to the field of flood control, and will not be described in detail here.

[0030] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a flood control device for water conservancy projects according to an embodiment of the present invention. A flood control device for water conservancy projects includes:

[0031] Several plates 1 are spliced ​​together to form a flood control structure. Each plate 1 has a chamber 11. Multiple limiting plates 15 are installed in the chamber 11. A bottom plate 16 is connected to the bottom of the back of the plate 1.

[0032] The drainage mechanism 2 includes a drainage end 21, a water-blocking end 22, a supporting column 24, and a telescopic end 25. A drainage end 21 is provided on one of the plates 1. A water-blocking end 22 for blocking the drainage end 21 is slidably connected in the chamber 11. A supporting column 24 is fixed on the water-blocking end 22. One end of the supporting column 24 extends to the outside of the plate 1. A telescopic end 25 is provided on the outside of the plate 1. The telescopic part of the telescopic end 25 is connected to the supporting column 24. A water guide port 26 that cooperates with the drainage end 21 is provided on the back of the plate 1. A drainage pipe body is connected to the flange at the water guide port 26.

[0033] In this embodiment, multiple drainage outlets at different levels are provided on the plate 1, distributed from top to bottom. This allows for selective opening or closing of drainage outlets at specific heights based on flood levels, enabling precise control. Each plate 1 contains a chamber 11, within which multiple slidable water-blocking ends 22 are installed. These water-blocking ends 22 can move left and right along the grooves on the limiting plate 15, adjusting their position to block or open the corresponding drainage outlets. The baffle is connected to an external telescopic end 25 via a supporting column 24. The operator can control the telescopic end 25 to... The position of the baffle is precisely adjusted so that the drain outlet can be quickly opened for drainage when needed and closed to prevent leakage when not needed. When the baffle is in a specific position, its auxiliary port is aligned with the corresponding drain outlet to allow water to flow through. In another position, it is staggered to form a seal, effectively preventing water flow and ensuring the waterproof sealing of the device. To enhance the stability and functionality of the overall structure, water guiding mechanisms 3 are also provided at both ends of the plate 1, and a support mechanism 4 is set between the plate 1 and the base plate 16. This not only improves the water blocking effect but also increases the equipment's ability to withstand flood impacts.

[0034] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 6To improve the splicing efficiency between the panels 1, several auxiliary rods 12 are arranged sequentially from top to bottom on one side of the panel 1, and several positioning holes 13 that cooperate with the auxiliary rods 12 are arranged sequentially from top to bottom on the other side of the panel 1. Water guiding mechanisms 3 are also provided at both ends of the panel 1, and a support mechanism 4 is provided between the panel 1 and the base plate 16. The water guiding mechanism 3 includes a first water guiding block 31, a second water guiding block 32, a filter screen plate 33, several reinforcing plates 34, and spring strips 35. The first water guiding block 31 and the second water guiding block 32 are arranged on the front of the panel 1 and form a water guiding area. An arc-shaped filter screen plate 33 is provided between the first water guide block 31 and the second water guide block 32. A plurality of reinforcing plates 34 are provided from top to bottom near the filter screen plate 33 and between the first water guide block 31 and the second water guide block 32. A plurality of spring strips 35 are provided between the reinforcing plates 34 and the filter screen plate 33. The support mechanism 4 includes reinforcing ribs 41, supporting diagonal rods 42 and positioning cones 43. Reinforcing ribs 41 are provided at the connection between the plate body 1 and the bottom plate 16. Supporting diagonal rods 42 are detachably connected between the plate body 1 and the bottom plate 16, and a plurality of positioning cones 43 are provided on the bottom plate 16.

[0035] In this embodiment, the auxiliary rod 12 on one side of the plate 1 and the positioning hole 13 on the other side cooperate with each other, allowing multiple plates 1 to be quickly spliced ​​into an integral structure. This not only simplifies the installation process but also enhances the stability and sealing of the overall structure. The water guiding area formed by the first water guiding block 31 and the second water guiding block 32, located on the front of the plate 1, guides the water flow along a predetermined path, reducing the direct impact of the water flow on the baffle plate itself. The arc-shaped filter screen plate 33, located between the first water guiding block 31 and the second water guiding block 32, can effectively filter out large particles of debris carried in the water, preventing these debris from clogging the drain or damaging the equipment. Multiple reinforcing plates 34 arranged from top to bottom provide additional structural support, and the spring strips 35 between them and the filter screen plate 33 can provide cushioning when encountering large impacts, protecting the filter screen plate 33 from damage. The reinforcing ribs 41 provided at the connection between the plate 1 and the bottom plate 16 enhance the overall structure. The rigidity of the base plate 16 prevents deformation or damage caused by external pressure. The detachable support diagonal bar 42 can be adjusted in angle according to actual needs, providing additional support for the baffle plate and enhancing its flood resistance. The positioning cone 43 on the base plate 16 ensures that the baffle plate can be firmly fixed to the ground during installation, avoiding displacement due to water flow impact. Through the reasonable layout of the water guide block and the filter screen 33, the water flow can be effectively guided and impurities can be filtered, reducing the damage of water flow to the baffle plate and internal components, and extending the service life of the equipment. At the same time, the cooperation of the auxiliary rod 12 and the positioning hole 13 allows multiple plates 1 to be quickly and firmly spliced ​​together. The reinforcing rib 41, support diagonal bar 42 and positioning cone 43 work together to greatly improve the stability and compressive strength of the overall structure. The buffer function provided by the spring strip 35 can protect key components from damage when encountering large impacts. At the same time, the positioning cone 43 ensures that the baffle plate will not move easily, ensuring the safety and reliability of use.

[0036] In one embodiment, please refer to Figure 1 - Figure 7To facilitate adjustment of the liquid level by staff according to actual conditions, the surface of the plate 1 is provided with movable through holes 14 that cooperate with the bearing column 24. The drain end 21 includes multiple first drain ports 211, multiple second drain ports 212, and multiple third drain ports 213, which are arranged from top to bottom on the plate 1. The water blocking end 22 includes a first baffle 221, a second baffle 222, and a third baffle 223, which are slidably connected in the chamber 11. The first baffle 221 has several first auxiliary ports 2211 that cooperate with the first drain ports 211, and the second baffle 222 has several auxiliary ports 2211 that cooperate with the second drain ports 212. The second auxiliary port 2221 and the third baffle 223 are provided with a plurality of third auxiliary ports 2231 that cooperate with the third drain port 213. Each of the first baffle 221, second baffle 222, and third baffle 223 is provided with a supporting column 24. The first baffle 221, second baffle 222, and third baffle 223 can be located in a first or second position. When the first baffle 221, second baffle 222, and third baffle 223 are in the first position, the first drain port 211, second drain port 212, third drain port 213, and the first auxiliary ports 2211, second auxiliary ports 2221, and third auxiliary ports 2231 overlap for drainage. When the first baffle 221, second baffle 222, and third baffle 223 are in the second position, the first drain port 211... 1. The second drain outlet 212, the third drain outlet 213, the first auxiliary outlet 2211, the second auxiliary outlet 2221, and the third auxiliary outlet 2231 are misaligned to seal the drain end 21. The inner wall of the chamber 11 is also provided with a buffer end 23 that cooperates with the water-blocking end 22. The buffer end 23 includes a spring damper 231 and a limiting baffle 232. The spring damper 231 is disposed in the chamber 11, and the end of the spring damper 231 is connected to the limiting baffle 232. The bearing column 24 includes a first column 241, a second column 242, and a third column 243. The first column 241 is fixed to the first baffle 221, the second column 242 is fixed to the second baffle 222, and the third column 243 is fixed to the third baffle 223. The first column 241, the second column 242, the third column 243, the first column 241, the second column 242, the third column 243 are fixed to the third baffle 223. The first column 242 and the third column 243 both penetrate the plate 1 and extend to the outside of the plate 1. The plate 1 has movable through holes 14 for sliding the first column 241, the second column 242, and the third column 243. The first column 241, the second column 242, and the third column 243 are all connected to a telescopic end 25. The telescopic end 25 includes a first electric telescopic rod 251, a second electric telescopic rod 252, and a third electric telescopic rod 253. The first electric telescopic rod 251, the second electric telescopic rod 252, and the third electric telescopic rod 253 are all installed on the back of the plate 1, and are respectively connected to the first column 241, the second column 242, and the third column 243.The limiting plate 15 has a sliding groove, and the upper and lower ends of the first baffle 221, the second baffle 222, and the third baffle 223 are all slidably connected to the sliding groove by sliders.

[0037] In this embodiment, the movable through holes 14 on the surface of the plate 1 allow the supporting columns 24, such as the first column 241, the second column 242, and the third column 243, to slide freely within them. These supporting columns 24 are respectively fixed to the first baffle 221, the second baffle 222, and the third baffle 223, allowing these baffles to move left and right within the chamber 11. The first drain outlet 211, the second drain outlet 212, and the third drain outlet 213 are arranged on the plate 1 from top to bottom, with each drain outlet corresponding to an auxiliary outlet on a baffle. The first auxiliary outlet 2211, the second auxiliary outlet 2221, and the third auxiliary outlet 2231 are connected when the baffle... When the baffle is in the first position, the auxiliary port aligns with the corresponding drain port to form a drainage channel. When the baffle is in the second position, the auxiliary port is misaligned with the drain port, sealing the drain end 21 to prevent water from passing through. The first baffle 221, the second baffle 222, and the third baffle 223 can slide within the chamber 11, selectively opening or closing the drain port as needed. Precise control can be made according to changes in the flood level to ensure effective drainage or waterproofing. The first electric telescopic rod 251, the second electric telescopic rod 252, and the third electric telescopic rod 253 drive the baffle to move up and down by connecting to the bearing column 24, realizing automation. The operation improves response speed and accuracy. The buffer end 23 on the inner wall of chamber 11 includes a spring damper 231 and a limiting baffle 232, which can provide a buffering effect during the movement of the baffle, reduce impact force, protect the internal structure from damage, and help to smoothly adjust the position of the baffle. The upper and lower ends of the baffle are slidably connected to the grooves on the limiting plate 15 by sliders, ensuring the stability and directional consistency of the baffle during movement and avoiding deviation or jamming. By flexibly adjusting the position of the baffle, the opening and closing state of the drain outlets at different heights can be precisely controlled to adapt to changes in water level and ensure timely and accurate operation. The system effectively drains water, reducing damage caused by floods. The application of the telescopic end 25 enables automated operation, reducing the need for manual intervention, improving the system's response speed and stability, and reducing the risk of human error. The design of the buffer end 23 effectively absorbs impact forces, protects the safety of internal components, and extends the service life of the equipment. The limit plate 15 and the slide ensure the stability and directional consistency of the baffle during movement, preventing structural damage caused by improper operation or external impact. The support mechanism 4 further enhances the overall structural stability, ensuring good performance even under high-intensity water flow impact.

[0038] In one embodiment, please refer to Figure 1 - Figure 7To enhance the intelligence of the device, liquid level sensors at different heights are installed on the front of the plate 1 to control the extension and retraction of the telescopic end 25. This further improves the automation level and response speed of the equipment. Multiple liquid level sensors, such as ultrasonic liquid level sensors or capacitive liquid level sensors, are installed at different heights on the front of the plate 1. These sensors can monitor the changes in the current water level in real time. The liquid level sensors transmit the detected water level information to the control system, such as a PLC controller. The control system determines the current water level based on the received data and decides whether the position of the baffle needs to be adjusted. When the liquid level sensor detects a specific water level, the control system triggers a corresponding command to activate the corresponding telescopic end 25, such as the first electric telescopic rod 251, the second electric telescopic rod 252, or the third electric telescopic rod 253. If the water level reaches the height of the first drain outlet 211, the system commands the first electric telescopic rod 251 to drive the first column 241 to move to the left, so that the first auxiliary port 2211 on the first baffle 221 is aligned with the first drain outlet 211. Alignment of 11 drain outlets opens the drainage channel; conversely, if the water level drops, the corresponding drain outlets are closed to prevent leakage. The system continuously monitors water level changes and dynamically adjusts the position of each baffle according to actual needs. Once the water level exceeds the set safety threshold, the system can also issue an alarm signal to remind operators to take further measures. The automated liquid level monitoring and control system can quickly respond to water level changes and adjust the baffle position in a timely manner to ensure efficient drainage or waterproofing, avoiding losses caused by human delays. Utilizing sensor technology to achieve automatic control reduces the need for manual intervention and improves the system's intelligence level. Especially in emergency situations, it can react quickly and enhance flood control capabilities. By precisely controlling the opening and closing of the drain outlets, the drainage volume can be flexibly adjusted according to actual needs, avoiding water waste caused by excessive drainage, while also ensuring necessary flood control requirements. Real-time monitoring and automatic adjustment functions help maintain a stable water level and prevent disaster risks caused by sudden flood rises. In addition, the introduction of a buffer mechanism also protects the equipment from impact damage and extends its service life.

[0039] To better understand this invention, the following is combined with... Figures 1 to 7The technical solution of the present invention is described in detail as follows: First, the plates 1 are spliced ​​together. Multiple plates 1 are spliced ​​together into an integral structure by means of auxiliary rods 12 and positioning holes 13, ensuring that each plate 1 is tightly connected to ensure sealing and structural stability. Water guiding mechanisms 3, such as first water guiding block 31, second water guiding block 32, and filter screen plate 33, are installed at both ends of each plate 1. Reinforcing ribs 41, supporting diagonal rods 42, and positioning cones 43 are set between the plate 1 and the bottom plate 16. One of the plates 1 is provided with a drain end 21. Check whether the first drain outlet 211, second drain outlet 212, and third drain outlet 213 on the plate 1 are unobstructed. Confirm that the first baffle 221 and the second baffle are slidably connected in the chamber 11. 222 and the third baffle 223, along with their corresponding first auxiliary port 2211, second auxiliary port 2221, and third auxiliary port 2231, are in their initial positions, typically closed. The first column 241, second column 242, and third column 243 are connected to their respective first electric telescopic rods 251, second electric telescopic rod 252, and third electric telescopic rod 253, ensuring that these telescopic ends 25 are mounted on the back of the plate 1 and connected to the PLC controller. Multiple liquid level sensors are installed at different heights on the front of the plate 1. In this application, ultrasonic liquid level sensors are installed to ensure that the sensors can monitor the current water level changes in real time and transmit the data to the PLC controller. After assembly, the control power is turned on. After ensuring all sensors and telescopic ends 25 are functioning properly, the device enters standby mode, monitoring water level changes in real time. The level sensor continuously monitors water level changes and transmits the data to the PLC controller. The PLC controller determines the current water level based on the received data and decides whether the baffle position needs adjustment. When the level sensor detects a specific water level, the control system triggers a corresponding command to activate the corresponding telescopic end 25. If the water level reaches the height of the first drain outlet 211, the PLC controller commands the first electric telescopic rod 251 to drive the first column 241 downwards, aligning the first auxiliary port 2211 on the first baffle 221 with the first drain outlet 211, thus opening the drainage channel. Similarly, if the water level rises further to the height of the second drain outlet 212 or the third drain outlet 213, the PLC controller will open the second drain outlet 212 or the third drain outlet 213 in sequence. Conversely, if the water level drops, the drain outlet will be closed accordingly to prevent leakage. During the movement of the baffle, the spring damper 231 installed on the inner wall of the chamber 11 provides a buffering effect, reduces the impact force, protects the internal structure from damage, and helps to smoothly adjust the position of the baffle. The sensor continuously monitors the water level changes and dynamically adjusts the position of each baffle according to actual needs. Once the water level exceeds the set safety threshold, the PLC control can also be electrically connected to an external speaker to issue an alarm signal when necessary, reminding the operator to take further measures.

[0040] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
