[0002] A waterproof coiled material is a rollable sheet waterproof material, which is mainly used for building walls, roofs, tunnels, roads and other sites, and serves as a flexible building material product to resist external rainwater and groundwater seepage. It is one of the important varieties of building engineering waterproof materials.

[0003] Generally, the waterproof coiled material already has good waterproof performance when leaving the factory and can be directly constructed. However, the existing waterproof coiled material has single performance. Currently, the waterproof coiled materials can be mainly divided into three categories: asphalt waterproof coiled materials, polymer modified waterproof coiled materials and synthetic polymer waterproof coiled materials, and their service life is short in some harsh environments; for example, a pumped storage power station not only needs to have good compressive waterproof performance, but also be corrosion-resistant. The existing solution is rather cumbersome. Generally, after laying the coiled material with single performance, a waterproof and anticorrosive material is used to process its surface, resulting in a cumbersome process.

[0004] Therefore, it is necessary for us to design a coiled material polyurea coating spraying device for a pumped storage power station to solve these problems. Content of the Utility Model

A spraying pipe 4 is arranged on the main support frame 1 above the adjusting plate 2. A material box 10 and a feeding pump 11 are arranged on one side of the main support frame 1. The output end of the feeding pump 11 is connected to the material box 10, and the output end of the feeding pump 11 is connected to the spraying pipe 4. A material - releasing support 17 and a material - collecting support 18 are also arranged on the main support frame 1. A material - collecting motor 20 and a winding wheel 19 are arranged on the material - collecting support 18. The output end of the material - collecting motor 20 is connected to the winding wheel 19.

[0029] Specifically, there are at least two rotating rollers 5, and the two rotating rollers 5 are respectively rotatably installed on both sides of the adjusting plate 2.

[0030] Specifically, a scraper 6 is also arranged on the adjusting plate 2. An installation groove 23 is arranged on the scraper 6. A scraping knife 24 is slidably arranged in the installation groove 23. The cutting edge of the scraping knife 24 is located outside the installation groove 23. An adjusting screw 26 is also connected to the scraper 6 by thread. One end of the adjusting screw 26 is fixedly provided with an adjusting knob 8, and the other end is rotatably connected to the scraping knife 24.

[0031] Specifically, an adjusting frame 9 is fixedly arranged on the main support frame 1 above the adjusting plate 2. The spraying pipe 4 is connected to the main support frame 1 through the adjusting frame 9. A plurality of nozzles 7 are also arranged on the spraying pipe 4.

[0032] Specifically, the output end of the feeding pump 11 is provided with a feeding pipe 13. The free end of the feeding pipe 13 is provided with a three - way valve 16 and a pressure gauge 15. The spraying pipe 4 is connected to one end of the three - way valve 16, and the other end of the three - way valve 16 is provided with a return pipe 14. The free end of the return pipe 14 is located inside the material box 10.

[0033] Specifically, a material - receiving groove 22 is also arranged on the adjusting plate 2. The free end of the material - receiving groove 22 is located above the material box 10.

[0034] Specifically, the input end of the feeding pump 11 is connected to the material box 10 through a feeding pipe 25, and a filter 12 is also arranged on the feeding pipe 25.

[0035] Specifically, a scale is arranged on the side wall of the scraping knife 24.

[0036] Specifically, the materials of the winding wheel 19 and the spiral strips 21 are rubber.

[0037] Working process of this embodiment: When in use, place the coil material to be processed on the feeding support 17. The waterproof coil material supported by the feeding support 17 can rotate. Then, pass the end of the waterproof coil material around the rotating roller 5 on one side of the adjusting plate 2, and successively pass under the nozzle 7 of the spraying pipe 4 and the scraper 24, then pass through the dryer 3 and around another rotating roller 5. Finally, fix the end of the coil material on the winding shaft, and place the winding shaft on the winding support. The winding wheel 19 on the winding support will fit with the winding shaft.

[0038] When it is necessary to process the waterproof coil material again, first pour the prepared polyurea raw material into the material tank 10, and then start the feeding pump 11. The feeding pump 11 will suck out the polyurea raw material in the material tank 10 through the feeding pipe 25, and after being filtered by the filter 12, transport the polyurea raw material to the spraying pipe 4 through the feeding pipe 13. At this time, connect the feeding pipe 13 and the spraying pipe 4 through the three-way valve 16. After the polyurea raw material enters the spraying pipe 4, it will be evenly sprayed out through the nozzle 7 and fall on the coil material below.

[0039] Then start the winding motor 20. The winding motor 20 will drive the winding wheel 19 to rotate. Since the winding wheel 19 is made of rubber, when the winding wheel 19 rotates, it will drive the fitting winding shaft to rotate through friction, and the coil material will be wound after the winding rotates.

[0040] When the coil material is being wound, due to the mutual friction between the coil material and the spiral strip 21 made of rubber on the rotating roller 5, the rotating roller 5 will rotate as the coil material moves. The spiral strip 21 on the rotating roller 5 has two ends with opposite spiral directions. Therefore, when the rotating roller 5 rotates, the spiral strip 21 will push the coil material in the middle or on both sides. In this embodiment, in order to prevent the coil material from wrinkling during the unwinding process, when the rotating roller 5 rotates, the spiral strip 21 will push the coil material to both sides, which can keep the coil material flat and prevent the coil material from wrinkling, resulting in incomplete spraying of polyurea and affecting the use effect.

[0041] After the nozzle 7 sprays the polyurea onto the coil material, the coil material will pass under the scraper 24 and be wound by the winding shaft after passing through the dryer 3. During this process, because the surface of the scraper 24 is provided with scales and is installed in the installation groove 23 on the scraper 6 through the adjusting screw 26, the length of the scraper 24 extending out of the installation groove 23 can be adjusted by rotating the adjusting knob 8, so as to control the thickness of the polyurea sprayed on the surface of the coil material. When the polyurea sprayed on the surface of the coil material is too thick, it will be scraped off by the scraper 24. At the same time, because the scraper 6 is inclined, when the scraper 24 scrapes off the polyurea on the surface of the coil material, it will flow along the scraper 24 and be blocked by the scraper 24 into the material receiving groove 22, and then flow back to the material tank 10 through the material receiving groove 22 for reuse.

[0042] The coil whose thickness has been trimmed by the doctor blade 24 will pass through the dryer 3, and the moisture in the polyurea sprayed on the surface of the coil will be quickly dried by the dryer 3, so that the polyurea can firmly adhere to the coil. The dried coil will be wound by the winding shaft for easy storage and use.

[0043] The above has described an embodiment of the present invention in detail, but the content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
