The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a sealing and clamping device for the connection between a geomembrane and a seepage-proof wall, such as... Figure 1-4 As shown, the sealing and clamping device at the connection between the geomembrane and the impermeable wall includes: a metal plate 1 for sealing the connection between the geomembrane and the impermeable wall; a winding shaft 2 for winding the metal plate 1 and a fixing shaft 3 for supporting the metal plate 1, respectively fixed on both sides of the metal plate 1; a rotating shaft 4 installed on the winding shaft 2, with an extension frame 5 rotatably sleeved on the rotating shaft 4; a fixing block 6 fixed on the extension frame 5, with a fixing bolt 7 threaded on the fixing block 6 for stabilizing the winding state of the metal plate 1; and a limiting member provided on the metal plate 1 for stabilizing the metal plate.

[0023] In this embodiment, by setting the metal plate 1, the connection between the geomembrane and the anti-seepage wall is sealed, effectively improving the sealing effect and preventing leakage. By setting the winding shaft 2 and the fixing shaft 3, the metal plate 1 is wound up and supported, so that the metal plate 1 can be easily stored when not in use, reducing the floor space and making it easy to carry and store. By setting the rotating shaft 4, the extension frame 5 and the fixing block 6, and cooperating with the fixing bolt 7 threadedly connected to the fixing shaft 3, the winding state of the metal plate 1 is stabilized, preventing the metal plate 1 from spreading out during storage or use, thus improving the stability and reliability of the device. By setting the limiting component, the metal plate 1 can remain stable during use, further enhancing the sealing and pressing effect at the connection between the geomembrane and the anti-seepage wall.

[0024] In a further preferred embodiment of the present invention, the limiting member includes a connecting rope 10 mounted on the metal plate 1, a fixing cone 11 fixed on the connecting rope 10 and insertable into the ground, and an adjusting block 12 mounted on the fixing cone 11 for providing an operating grip point.

[0025] In this embodiment, by setting the connecting rope 10, the metal plate 1 and the fixed cone 11 are connected, ensuring the stability of the metal plate 1 during use and preventing it from shifting due to external forces. By setting the fixed cone 11, the metal plate 1 is firmly fixed underground, allowing the metal plate 1 to better seal and compress the connection between the geomembrane and the seepage barrier, thus improving the sealing effect. By setting the adjusting block 12, a gripping point is provided for the operator, making it more convenient and less strenuous to insert or pull out the fixed cone 11, thereby improving work efficiency.

[0026] In a further preferred embodiment of the present invention, the metal plate 1 is provided with a slot 9 for providing a through channel for the fixed cone 11, the metal plate 1 is provided with a reinforcing ring 14 for reinforcing the slot 9, and a sealing gasket 15 that can contact the geomembrane and the impermeable wall is installed on the metal plate 1.

[0027] In this embodiment, by setting the bayonet 9, a through channel is provided for the fixing cone 11, allowing the fixing cone 11 to pass smoothly through the metal plate 1 and be inserted into the ground, thus achieving a stable fixation of the metal plate 1. By setting the reinforcing ring 14, the structural strength of the bayonet 9 is enhanced, preventing damage to the bayonet 9 during insertion or removal of the fixing cone 11 and extending the service life of the metal plate 1. By setting the sealing gasket 15, the metal plate 1 can better contact the geomembrane and the seepage prevention wall during installation, forming a tight seal and effectively preventing leakage.

[0028] In a further preferred embodiment of the present invention, the top of the rotating shaft 4 is provided with a servo motor 19 for driving the winding shaft 2 to rotate to receive the metal plate 1. The servo motor 19 is fitted with a support frame 18 for supporting the servo motor 19. The output shaft of the servo motor 19 is rotatably connected to the support frame 18. A transmission structure is provided between the servo motor 19 and the rotating shaft 4.

[0029] In this embodiment, by setting a servo motor 19 (taking a Siemens 1FT7 servo motor as an example), the winding shaft 2 is driven to rotate to automatically store the metal plate 1, which greatly improves work efficiency and reduces the tediousness of manual operation. By setting a support frame 18, the servo motor 19 is supported, ensuring the stability of the servo motor 19 during operation and preventing it from falling off or being damaged due to vibration. By rotatably connecting the output shaft of the servo motor 19 to the support frame 18, the stability of the servo motor 19 is further enhanced, while ensuring its rotational flexibility. By setting a transmission structure between the servo motor 19 and the rotating shaft 4, the power of the servo motor 19 can be effectively transmitted to the rotating shaft 4, thereby driving the winding shaft 2 to rotate and realizing the automatic storage of the metal plate 1.

[0030] In a further preferred embodiment of the present invention, the transmission structure includes a limiting cylinder 16 fixed on the rotating shaft 4, and a limiting block 17 connected to the output shaft flange of the servo motor 19 is movably installed inside the limiting cylinder 16. The limiting block 17 is a polygonal right prism and is in contact with the inner wall of the limiting cylinder 16.

[0031] In this embodiment, the limiting cylinder 16 serves to accommodate and position the limiting block 17, providing a stable support foundation for the transmission structure. By setting the limiting block 17, which is connected to the flange of the output shaft of the servo motor 19, and the limiting block 17 is a polygonal right prism that contacts the inner wall of the limiting cylinder 16, the power of the servo motor 19 is effectively transmitted to the rotating shaft 4, ensuring smooth power transmission. At the same time, the polygonal right prism design prevents the limiting block 17 from rotating relative to the limiting cylinder 16, improving the reliability of the transmission.

[0032] In a further preferred embodiment of the present invention, a handle 8 for providing an operating grip point is installed on the fixed shaft 3, an extension rod 13 for expanding the operating point is fixed on both sides of the adjusting block 12, and a handle 20 for providing an operating grip point is installed on the support frame 18.

[0033] In this embodiment, by providing a handle 8, the operator is given a gripping point, making it easier and less strenuous to move or install the fixed shaft 3 and the related metal plate 1 structure. By fixing extension rods 13 on both sides of the adjusting block 12, the operating points are expanded, allowing the operator to operate the adjusting block 12 from different angles and positions, thereby more flexibly controlling the insertion and removal of the fixed cone 11. By installing a handle 20 on the support frame 18, another gripping point is provided for the operator, facilitating operation when installing, debugging, or maintaining the servo motor 19 and its related structures.

[0034] In a further preferred embodiment of this utility model, the length ratio of the connecting rope 10 to the fixed cone 11 is 2:1, and the extension frame 5 is threaded with a limiting bolt that can contact the rotating shaft 4 to stabilize the direction of the extension frame 5. The limiting bolt is equipped with an anti-slip pad to increase friction.

[0035] In this embodiment, by setting the length ratio of the connecting rope 10 to the fixed cone 11 to 2:1, the effect of reasonably distributing the structural proportions is achieved. This ensures that the connecting rope 10 has sufficient length to flexibly adjust the position of the fixed cone 11, and also ensures that the fixed cone 11 has sufficient length to be firmly inserted into the ground, thus enhancing the fixing effect of the metal plate 1. By threading a limiting bolt on the extension frame 5, the direction of the extension frame 5 is stabilized, preventing unnecessary rotation or displacement of the extension frame 5 during use. By installing anti-slip pads on the limiting bolts, the friction between the limiting bolts and the rotating shaft 4 is increased, allowing the limiting bolts to more firmly fix the extension frame 5, further improving the stability and reliability of the device.

[0036] In a further preferred embodiment of this utility model, the metal plate 1 is made of stainless steel, the sealing gasket 15 is made of silicone and covers the connection between the geomembrane and the seepage barrier wall, and the metal plate 1 is coated with an anti-corrosion coating.

[0037] In this embodiment, by setting the metal plate 1 to be made of stainless steel, the durability and corrosion resistance of the device are improved. Stainless steel is strong and not easy to rust, which can ensure that the metal plate 1 maintains stable performance during long-term use. By setting the sealing gasket 15 to be made of silicone and covering the connection between the geomembrane and the seepage barrier, a good sealing effect is achieved. The silicone material is soft and has excellent sealing performance, which can effectively prevent leakage and improve the sealing effect. By spraying an anti-corrosion coating on the outside of the metal plate 1, the corrosion resistance of the metal plate 1 is further enhanced, its service life is extended, and the device can operate stably for a long time in harsh environments.

[0038] In summary, compared with related technologies, this device effectively seals the connection between the geomembrane and the impermeable wall by setting the metal plate 1, thereby improving the sealing effect and preventing leakage. The setting of the winding shaft 2 and the fixing shaft 3 facilitates the storage of the metal plate 1, reduces the floor space, and makes it easy to carry and store. The setting of the rotating shaft 4, the extension frame 5, the fixing block 6 and the fixing bolt 7 stabilizes the winding state of the metal plate 1, improving the stability and reliability of the device. The setting of the limiting component keeps the metal plate 1 stable during use and enhances the sealing and pressing effect.
