[0002] There are many small irrigation canals, such as farm canals and field canals, in China's irrigation districts. In the past, these canals were mostly made of earth, and people usually used simple methods such as manually removing soil or using wooden planks to control the flow of water.

[0003] Nowadays, most channels have been replaced with precast concrete channels, and the simple methods of manually removing soil or using wooden planks are no longer sufficient to effectively control the water flow. Currently, most precast concrete channels adopt a U-shaped design. For this type of channel, a common solution for installing gates is to first convert the U-shaped channel into a rectangular channel at the location where a gate is needed, then recast a raised platform inside the U-shaped channel, and finally install a simple rectangular gate at the raised platform location in the rectangular channel.

[0004] However, most of the gates installed in the U-shaped irrigation canals are simple rectangular gates, requiring pre-construction of civil engineering formwork before pouring the slab, which not only results in a long construction period but also significant construction difficulty.

[0025] Example 1 A specific embodiment of the present invention, such as Figures 1 to 6As shown, a flexible water-stopping device is disclosed, which is a gate applied to stop water in a channel 100, wherein the channel 100 has a U-shaped structure; The flexible water-stopping device includes a water-stopping mechanism and a driving mechanism. The water-stopping mechanism has a flexible water-stopping material 19, which serves as a water-stopping surface to intercept water flow. The flexible water-stopping material 19 has a bottom surface and two side surfaces. The two side surfaces of the flexible water-stopping material 19 are fixedly and sealingly connected to the side wall of the channel 100. The driving mechanism is installed above the channel 100. The driving mechanism has a motor 7 and a transmission assembly. The transmission assembly is connected to the bottom surface of the flexible water-stopping material 19, and the motor 7 adjusts the angle between the bottom surface of the flexible water-stopping material 19 and the bottom wall of the channel 100 between 0° and 90° via the transmission assembly. The water-stopping mechanism has a water-stopping state and a water-passing state. The water-stopping and water-passing states can be adjusted by adjusting the angle between the bottom surface of the water-stopping flexible material 19 and the bottom wall of the channel 100.

[0026] For example, in the water-stopped state, the bottom surface of the water-stopping flexible material 19 is perpendicular or nearly perpendicular to the bottom wall of the channel 100; in the water-passing state, the water-stopping flexible material 19 has an overall U-shaped structure, and the bottom surface of the water-stopping flexible material 19 is in contact with the bottom wall of the channel 100, with the two almost on the same plane.

[0027] It should be noted that the upstream end of the water-stop flexible material 19, that is, the end part facing the water flow direction, is fixedly and sealed to the side wall and bottom wall of the channel 100. The middle and downstream parts of the two sides and bottom of the water-stop flexible material 19 along the water flow direction are not fixedly connected to the side wall of the channel. The middle and downstream parts of the water-stop flexible material 19 are not fixedly connected to the side wall and bottom wall of the channel 100. This is to ensure that the bottom surface of the water-stop flexible material 19 can be normally flipped up to the water-stopping state.

[0028] In this embodiment, the drive mechanism further includes a top beam 13, which is fixed above the channel 100 by expansion bolts and spans the channel 100; a reducer 8 is provided between the motor 7 and the transmission assembly, the reducer 8 is mounted on the top beam 13, and the motor 7 is mounted on the reducer 8.

[0029] In one optional embodiment, the transmission assembly includes a transmission shaft 14, a slide rail 6, and a wire rope assembly. The bottom end of the slide rail 6 is connected to the water-stop flexible material 19. The output shaft of the motor 7 is connected to the input shaft of the reducer 8. The output shaft of the reducer 8 is connected to one end of the transmission shaft 14. The other end of the transmission shaft 14 is rotatably mounted on the bracket 4 via a bushing 12. The bracket 4 is mounted on the top beam 13. The wire rope assembly has a hub 11 and a wire rope 26. The hub 11 is mounted on the transmission shaft 14, and the wire rope 26 is wound around the hub 11. Each of the two moving ends of the wire rope 26 is provided with a crimping end 27. The two crimping ends 27 are respectively fixedly connected to the pins 15 at both ends of the slide rail 6. The motor 7 drives the hub 11 to rotate forward and reverse through the transmission shaft 14. The rotation of the hub 11 drives the wire rope 26 to wind, thereby controlling the up and down sliding and lifting of the slide rail 6.

[0030] like Figure 7 As shown, the two free ends of the wire rope 26 are provided with two crimping ends 27, which are connected to two pins 15 at both ends of the slide rail 6 respectively. The pins 15 are provided with insertion holes for the crimping ends 27 to be inserted. The crimping ends 27 are fixedly installed in the insertion holes. The end of the slide rail 6 is connected to the rotating bracket 16 by a pin or bolt.

[0031] It should be noted that the raising and lowering of the slide rail 6 mentioned here is not a strictly vertical upward and downward movement, but rather a linear reciprocating movement in an inclined direction, causing the bottom end of the slide rail 6 to move along the inclined direction as well. When the slide rail 6 moves downward at an angle, the bottom end of the slide rail 6 pulls the water-stopping flexible material 19 down along the water flow direction until it contacts the bottom wall of the channel, thus enabling water to flow through the channel; when the slide rail 6 moves upward at an angle, the bottom end of the slide rail 6 rises accordingly, pulling the water-stopping flexible material 19 up along the downstream end of the water flow direction until the water-stopping flexible material 19 is pulled to a vertical or near-vertical state, trapping the water and thus stopping the channel from flowing.

[0032] In one alternative embodiment, the bracket 4 is provided with a guide roller shaft 3, which is used for limiting and guiding the slide rail 6.

[0033] The number of guide rollers 3 can be two, four, or even more, with at least one guide roller 3 on each side of the slide rail 6. For example, the bracket 4 has four guide rollers 3, each located on one of the four parallel edges of a cuboid. The slide rail 6 is movably mounted within the rectangular space formed by the four guide rollers 3, and the length direction of the slide rail 6 is parallel to the edges of the cuboid, allowing it to move under the limiting and guiding action of the four guide rollers 3. The limiting action of the four guide rollers 3 prevents the slide rail 6 from colliding with the hub shaft 11 during movement. Simultaneously, the guide rollers 3 also enhance the movement flexibility of the slide rail.

[0034] In one alternative embodiment, the bracket 4 is a U-shaped bracket, the drive shaft 14 is rotatably mounted on the U-shaped bracket via two bushings 12, and the hub shaft 11 is mounted on the drive shaft 14 and located within the U-shaped space of the U-shaped bracket.

[0035] In one alternative embodiment, the motor 7 is provided with a motor cover 5; and / or, the U-shaped bracket is provided with a protective component on its exterior, and the protective component is provided with a channel for the slide rail 6 to pass through.

[0036] Optionally, the protective assembly includes a detachably connected shield 1 and shield 2, shield 2 covering the outside of the U-shaped bracket, and shield 1 being detachably installed at the top opening of shield 2.

[0037] In this embodiment, two Hall sensors 9 are mounted on the bracket 4 via Hall sensor brackets 10. The two Hall sensors 9 are located on the upper and lower sides of the hub shaft 11. Two magnets are embedded in the inner side of the slide rail 6. The signal surface of the Hall sensor 9 faces the inner side of the slide rail 6, towards the side where the magnet is located. One magnet and one Hall sensor 9 form a pair. When the slide rail 6 slides up and down, when the magnet moves to the monitoring position of the Hall sensor 9, it generates a signal, which is transmitted to the program to achieve the upper and lower limit positions, ensuring the safe operation of the entire gate. The specific positions of the two magnets on the slide rail 6 are set according to the position of the flexible mechanism when it is opened and closed. When the water-stopping device is in the closed state, the lower magnet aligns with the corresponding Hall sensor, triggering the lower limit signal, and the motor stops running. When the water-stopping device is opened to the preset position, the upper magnet contacts the other Hall sensor, generating the upper limit signal, and the motor immediately stops working. Through this precise position sensing mechanism, equipment damage caused by excessive movement of the slide rail is effectively avoided, ensuring the stability and safety of the drive mechanism.

[0038] The assembly process and working principle of the drive mechanism are as follows: The top beam 13 is fixed above the channel 100 and spans the channel 100 using expansion bolts. Then, the reducer 8 is installed on the top beam 13, and the motor 7 is installed on the reducer 8. The motor 7 is protected by the motor cover 5. Mount bracket 4 on top beam 13, pass drive shaft 14 through hole in reducer bracket, and install bushing 12 on bracket 4 and lubricate shaft. Hub shaft 11 passes through drive shaft 14 and is fixed with key and snap ring. Wrap stainless steel wire rope around hub shaft 11. Connect the two crimped ends 27 of wire rope 26 to the two pins 15 at both ends of slide rail 6 respectively. Then connect the end of slide rail 6 to rotating bracket 16 through pin or bolt. When installing slide rail 6, slide rail 6 needs to pass through the gap between multiple guide roller shafts 3 to limit the position of slide rail 6 and prevent it from deviating. Mount Hall sensor 9 on Hall sensor bracket 10. Hall sensor bracket 10 is mounted on bracket 4. The signal surface of Hall sensor 9 faces the inside of slide rail 6. Since slide rail 6 is connected to rotating bracket 16, slide rail 6 moves and drives rotating bracket 16 to swing, thereby making the entire water-stopping mechanism move accordingly, achieving the effect of opening and closing gate.

[0039] In this embodiment, the flexible waterproofing material 19 can be one or more of the following: rubber, silicone, TPU, EPDM, modified PLA, waterproof fabric, and fiber-reinforced synthetic waterproofing materials. Rubber, such as butyl rubber rolls, is preferred.

[0040] In this embodiment, a rectangular frame is provided on the bottom surface of the water-stop flexible material 19. A rotating bracket 16 is provided on the downstream end of the rectangular frame 16 along the water flow. The rotating bracket 16 is rotatably connected to the slide rail 6 via a pin 29. The rectangular frame is fixedly connected to the bottom surface of the water-stop flexible material 19. The lower end of the slide rail 6 drives the downstream end of the rectangular frame to rise and fall along the water flow by rotating the rotating bracket 16, thereby realizing the water passage and water stop of the water-stop material.

[0041] In one alternative embodiment, the rectangular frame is assembled from a first fixing plate 17 and a second fixing plate 18, and the rectangular frame is fixedly disposed at the middle portion of the bottom surface of the flexible water-stop material 19. Optionally, the middle portion of the bottom surface of the flexible water-stop material 19 is clamped and fixed between the first fixing plate 17 and the second fixing plate 18, and the first fixing plate 17 and the second fixing plate 18 are connected by bolts. Of course, the first fixing plate 17 and the second fixing plate 18 can also be disposed on the same side of the bottom surface of the flexible water-stop material 19, as long as they are fixed to the bottom surface of the flexible water-stop material 19.

[0042] In one optional embodiment, the upstream end of the water-stopping flexible material 19 facing the water flow is fixedly connected to the bottom wall and side walls of the channel 100 via a U-shaped frame plate 28, and a sealing treatment is performed at the connection point between the U-shaped frame plate 28 and the channel 100; the two sides of the water-stopping flexible material 19 are respectively fixedly connected to the side walls of the channel 100 via a pressure plate 20, the pressure plate 20 being located in the middle and upstream position of the water-stopping flexible material 19, closer to the upstream end of the water-stopping flexible material 19. The two pressure plates 20 and the U-shaped frame plate 28 constrain the water-stopping flexible material 19 to maintain its U-shaped structure under water flow conditions. The distance between the pressure plate 20 and the fixed connection position of the side wall is 50-80 cm, which can be determined according to the actual size of the channel. The pressure plate 20 provides sufficient space for the downstream part of the water-stop flexible material 19 to rotate 90°. The main purpose of the pressure plate 20 being fixedly connected to the side wall of the channel 100 is to press down the water-stop flexible material 19, ensuring that it always fits against the side wall of the channel, so as to achieve the best water-stopping effect when the gate is fully closed. The main function of the U-shaped frame plate 28 is to act as a gasket and pressure plate to prevent damage to the water-stop flexible material 19. The water-stop flexible material 19 is fixed to the side wall and bottom wall of the channel by anchor bolts.

[0043] The fabrication and installation process of the water-stopping mechanism is as follows: First, cut the flexible water-stopping material 19. The flexible water-stopping material 19, when laid flat, is trapezoidal, with the two corners of the trapezoidal shape being curved in the downstream direction of the water flow. Then, place the fixing plate 17 and fixing plate 28 on both sides of the middle part of the bottom surface of the flexible water-stopping material 19. Assemble and fix the fixing plate 17 and fixing plate 28 with bolts to form a rectangular frame. The rectangular frame is then fixedly connected to the flexible water-stopping material 19. The two sides of the flexible water-stopping material 19 are installed in the gate chamber according to the size of the gate chamber of the channel through the pressure plate 20 and the U-shaped frame plate 28. When installing the flexible water-stopping material 19, fold the entire flexible water-stopping material 19 into a U-shape and fit it into the channel 100. The two sides and the bottom surface of the upstream end of the flexible water-stopping material 19 are tightly attached to the side wall and bottom surface of the channel. The upstream end of the flexible water-stopping material 19 is fixedly connected to the inner wall and bottom wall of the channel using the U-shaped frame plate 28, and a sealing treatment is applied to the inner wall surface of the channel. Next, the rotating bracket 16 is installed on the top of the fixed plate 18, and then the rotating bracket 16 and the slide rail 6 are rotatably connected together with the pin 29, thereby completing the fabrication and installation of the water-stopping mechanism, as well as the connection between the drive mechanism and the water-stopping mechanism.

[0044] In one alternative embodiment, the flexible waterproofing device further includes a solar power supply mechanism configured to provide the flexible waterproofing device with the electrical energy required for its operation.

[0045] Specifically, the solar power supply mechanism includes a solar panel 21, a control cabinet 22, a solar pole 23, a clamp 24, and a solar mounting bracket 25. The lower end of the solar mounting bracket 25 is fixedly connected to the top beam 13 and connected to the reducer 8 by bolts. The solar pole 23 is mounted on the solar mounting bracket 25 via the clamp 24, and the solar panel 21 and control cabinet 22 are mounted on the solar pole 23. The battery inside the control cabinet 22 is connected to the electrical components of the flexible water-stopping device. The battery inside the control cabinet is a lithium battery with a long standby time, and the control cabinet has a mechanical switch for local control, and the opening degree can be displayed on the screen.

[0046] The assembly process of the solar power supply mechanism is as follows: First, connect the solar mounting bracket 25 and the reducer 8 with bolts. Then, install the solar pole 23 on the solar mounting bracket 25 with clamps 24. Next, install the solar panel 21 and control cabinet 22 and other accessories on the solar pole 23, and connect the wires at the same time.

[0047] The solar panel 21 converts solar energy into electrical energy and stores it in the battery inside the control cabinet 22, providing stable power for the motor and other electrical components of the device without the need for additional power lines. This is especially suitable for outdoor scenarios such as irrigation areas where there is no external power source. The control cabinet 22 has a built-in intelligent control system that can automatically start and stop the drive mechanism according to preset time or water level monitoring data, realizing the intelligent operation of the water-stopping device. It also has functions such as overload protection and low battery reminder, effectively improving the device's endurance and safety. The solar pole 23, through the combination connection structure of the clamp 24 and the solar mounting bracket 25, can flexibly adjust the installation angle of the solar panel 21 to ensure that it receives sunlight to the maximum extent, further optimizing energy conversion efficiency and reducing the operation and maintenance costs of the device.

[0048] Compared with the prior art, the flexible water-stopping device provided in this embodiment can achieve the following beneficial effects: 1. Compared to the current market practice of using agricultural canal gates that generally require reconstruction of the gate chamber and are installed by pouring concrete or attaching to the wall, resulting in a large workload, the flexible water-stopping device in this embodiment can be cut and fixed with flexible water-stopping material according to the curvature of the channel on site, offering a high degree of adaptability. During installation, only the top beam needs to be fixed to both ends of the gate chamber with expansion bolts, and then the water-stopping mechanism can be fixed to complete the installation quickly. This not only provides excellent water-stopping effect but also facilitates subsequent replacement and maintenance.

[0049] 2. The water-stopping mechanism is made of flexible material, and its opening and closing action is driven by steel wire rope. The opening and closing position is accurately located with the help of Hall sensor, which improves the control accuracy compared with the traditional screw and gear transmission method.

[0050] 3. It adopts solar power supply and has a built-in lithium battery in the control cabinet, which has a long standby time and is suitable for outdoor scenarios without power supply.

[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
