DETAILED DESCRIPTION

[0017] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0018] A high-strength geomembrane welded structure, such as Figure 1-Figure 4As shown, it includes a climbing welding machine 1, a support block 2, a motor 3, a driving wheel 4, a driven wheel 5, a bidirectional screw rod 6, a guide rod 7, a slider 8, a fixed plate 9 and a scraper 10. The right side of the climbing welding machine 1 is fixedly connected to the support block 2, the top of the support block 2 is installed with a motor 3, the output shaft of the motor 3 is installed with a driving wheel 4, the bottom of the support block 2 is opened with a through hole, the through hole is rotatably connected with a bidirectional screw rod 6, the front and rear sides of the bidirectional screw rod 6 are fixedly connected with the guide rod 7, the middle part of the bidirectional screw rod 6 is rotatably connected with the driven wheel 5, the driving wheel 4 and the driven wheel 5 are connected by a transmission belt, both ends of the bidirectional screw rod 6 are slidably connected with the slider 8, the two guide rods 7 pass through the slider 8, the bottom of the slider 8 is fixedly connected with the fixed plate 9, the ends of the fixed plate 9 away from each other are slidably connected with the connecting column 16, the bottom of the connecting column 16 is fixedly connected with the scraper 10, and the scraper 10 is inclined.

[0019] When it is necessary to weld the geomembrane, place the climbing welding machine 1 on the geomembrane so that two adjacent geomembranes pass between the two rubber rollers of the climbing welding machine 1. Start the climbing welding machine 1 to move it on the geomembrane and weld the adjacent geomembranes. When the climbing welding machine 1 moves along the edge of the geomembrane, the scraper 10 can scrape off the soil on the geomembrane. When it is necessary to control the distance between the two scrapers 10, start the motor 3 to rotate the output shaft to drive the driving wheel 4 to rotate. The driving wheel 4 rotates the driven wheel 5 through the transmission belt. The rotation of the driven wheel 5 drives the bidirectional screw 6 to rotate. The sliders 8 move away from each other along the two guide rods 7, so that the scrapers 10 move away from each other. The distance between the scrapers 10 is increased, the motor 3 is started to reverse the output shaft of the motor 3 and drive the driving wheel 4 to reverse, the driving wheel 4 reverses the driven wheel 5 through the transmission belt, the driven wheel 5 rotates to drive the bidirectional screw 6 to reverse, the sliders 8 are moved closer to each other along the two guide rods 7, so that the scrapers 10 are moved closer to each other, thereby shortening the distance between the scrapers 10, and the scrapers 10 can scrape off the soil on the geomembrane. By controlling the distance between the scrapers 10, the scrapers 10 can be suitable for cleaning geomembranes in narrow spaces, and have high cleaning efficiency, preventing soil from interfering with the welding of the geomembrane, resulting in low welding strength, and improving welding efficiency.

[0020] like Figure 1-Figure 4 As shown, the connecting column 16 is engaged with the fixing plate 9, the outer wall of the connecting column 16 has at least one clip, and the right side of the fixing plate 9 has a slide groove adapted to the clip of the connecting column 16. When the angle of the scraper 10 needs to be adjusted, the scraper 10 is moved downward, the connecting column 16 is separated from the fixing plate 9, and the scraper 10 is rotated to a suitable angle, and then the scraper 10 is moved upward to engage the connecting column 16 with the fixing plate 9 to complete the angle adjustment of the scraper 10 once, so that the angle of the scraper 10 can be adjusted by the clip on the connecting column 16, which can improve the practicality of the scraper 10.

[0021] like Figure 1-Figure 3As shown, a buckle 11 is also included. A notch is formed at one end of the fixing plate 9 away from each other, and a buckle 11 is installed at the notch. When the connecting column 16 is connected to the fixing plate 9, the buckle 11 is adjusted and clamped to the connecting column 16. When the scraper 10 needs to be removed or the angle of the scraper 10 needs to be adjusted, the buckle 11 is adjusted and released to the connecting column 16. The buckle 11 can prevent the scraper 10 from moving up and down when the creeping welding machine 1 is working, thereby ensuring the cleaning efficiency of the scraper 10.

[0022] like Figure 1 and Figure 2 As shown, a vacuum cleaner 12 and a brush 13 are also included. The vacuum cleaner 12 is installed in the middle of the support block 2. The suction end of the vacuum cleaner 12 passes through the support block 2. The suction end of the vacuum cleaner 12 is fixedly connected to the brush 13, and the brush 13 is in contact with the ground. When the creeping welding machine 1 moves, the vacuum cleaner 12 is started, and the vacuum cleaner 12 will suck away the dust on the geomembrane. The brush 13 can cooperate with the vacuum cleaner 12. After the brush 13 brushes away the dust adhered to the surface of the geomembrane, the vacuum cleaner 12 will suck away the dust again to prevent some dust from adhering to the surface of the geomembrane, resulting in loose welding, and further improve welding efficiency.

[0023] like Figure 1 As shown, a pressure roller 15 is also included, and the bottom of the climbing welding machine 1 is fixedly connected with the pressure roller 15. When the climbing welding machine 1 is working, the pressure roller 15 presses the welding position of the two geomembranes to press the wrinkles on the geomembranes flat, prevents the wrinkles on the geomembranes from causing difficulty in fixing and forming during welding, avoids the wrinkles from affecting the welding effect, and makes the welding of the geomembranes more firm.

[0024] like Figure 1 and Figure 2 As shown, it also includes protrusions 14. Twenty-four protrusions 14 are fixedly connected to the two rubber rollers of the climbing welding machine 1, and the protrusions 14 are evenly distributed on the two rubber rollers. Different types of geomembranes have different surface roughness. When using geomembranes with relatively smooth surfaces, two geomembranes pass through the rubber rollers of the climbing welding machine 1. The protrusions 14 can increase the friction between the surface of the rubber roller and the geomembrane, preventing the rubber roller from slipping and being unable to move the geomembrane, resulting in failure in welding the geomembrane.

[0025] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
