[0043] Please refer to Figures 1-11 On the basis of the above embodiment, in another embodiment of the present application, the top surface of the protection inclined plate 3 is provided with a water scraping device 9 for reducing water residue on the surface of the protection inclined plate 3.

[0044] The wiper device 9 comprises a hinged rod 91, a U-shaped sliding rod 92, a long rod 93, a plurality of V-shaped rods 94, the hinged rod 91 is hinged to the front side of the U-shaped through slot rod 82, the U-shaped sliding rod 92 is slidingly installed on the top surface of the protective inclined plate 3, and the rear side of the U-shaped sliding rod 92 is hinged to one end of the hinged rod 91 away from the U-shaped through slot rod 82, the long rod 93 is fixed to the top of the U-shaped sliding rod 92, the plurality of V-shaped rods 94 are uniformly and equidistantly fixed to the bottom of the long rod 93, and the V-shaped rods 94 are in contact with the top surface of the protective inclined plate 3. Through the arrangement of the above structure, the V-shaped rods 94 scrape the water adhered to the surface of the protective inclined plate 3, and the scraped water flows into the discharge chute 4 along the inclined surface of the V-shaped rod 94, thereby reducing the water content on the surface of the protective inclined plate 3, thereby avoiding the water promoting the aging process of the surface of the protective inclined plate 3, especially for some protective inclined plates 3 which are prone to deformation or corrosion due to moisture, long-term soaking and exposure to water, the surface of the protective inclined plate 3 is prone to cracking, discoloration, and deformation, thereby improving the service life and performance of the protective inclined plate 3.

[0045] The wiper device 9 further comprises an I-shaped wheel 95, an L-shaped telescopic rod 96, a column rod 97, a semi-arc block wheel 98, and a knocking rod 99. The I-shaped wheel 95 is rotatably installed on the top of the long rod 93, and the I-shaped wheel 95 is in contact with the top surface of the protective inclined plate 3. The semi-arc block wheel 98 is fixed to the outside of the rotating shaft of the I-shaped wheel 95. The L-shaped telescopic rod 96 is fixed to the top rear side of the long rod 93. The column rod 97 is embedded in the telescopic end bottom of the L-shaped telescopic rod 96. The knocking rod 99 is fixed to the telescopic end front side bottom of the L-shaped telescopic rod 96. The semi-arc block wheel 98 is externally fixed with a semi-arc block. The column rod 97 is cylindrical and located on the movement track of the semi-arc block of the semi-arc block wheel 98. Through the arrangement of the above structure, the knocking rod 99 knocks the long rod 93, the long rod 93 vibrates and drives the V-shaped rod 94 to vibrate, thereby promoting the speed of the water scraped by the V-shaped rod 94 to flow into the discharge chute 4, and accelerating the efficiency of the V-shaped rod 94 scraping the water on the surface of the protective inclined plate 3.

[0046] When the dam foundation body 1 is protected by the protection inclined plate 3, water is inevitably adhered to the surface of the protection inclined plate 3. When the U-shaped through slot rod 82 moves upward, the U-shaped through slot rod 82 pulls one end of the articulated rod 91 to move upward, and the other end of the articulated rod 91 drives the U-shaped slide rod 92 to move upward along the top of the protection inclined plate 3. When the U-shaped through slot rod 82 moves downward, the U-shaped through slot rod 82 pushes one end of the articulated rod 91 to move downward, and the other end of the articulated rod 91 drives the U-shaped slide rod 92 to move downward along the top of the protection inclined plate 3. Thus, the U-shaped slide rod 92 drives the V-shaped rod 94 to reciprocate along the top of the protection inclined plate 3, the V-shaped rod 94 scrapes the water adhered to the surface of the protection inclined plate 3, and the scraped water flows into the discharge chute 4 along the inclined surface of the V-shaped rod 94, thereby reducing the water content on the surface of the protection inclined plate 3, avoiding the aging process of the protection inclined plate 3 caused by water, especially for the protection inclined plate 3 made of material prone to deformation or corrosion, which is soaked in water for a long time and exposed to the sun, the surface of the protection inclined plate 3 is prone to cracking, fading, and deformation, thereby improving the service life and performance of the protection inclined plate 3. Meanwhile, the long rod 93 drives the I-shaped wheel 95 to move, under the friction between the I-shaped wheel 95 and the protection inclined plate 3, the protection inclined plate 3 drives the I-shaped wheel 95 to rotate, the I-shaped wheel 95 drives the semi-arc block wheel 98 to rotate, the semi-arc block of the semi-arc block wheel 98 pushes the cylindrical part of the column rod 97 to drive the extension end of the L-shaped telescopic rod 96 to move away from the long rod 93, the extension end of the L-shaped telescopic rod 96 drives the knocking rod 99 to move away from the long rod 93, when the semi-arc block of the semi-arc block wheel 98 no longer pushes the cylindrical part of the column rod 97, under the elastic force of the L-shaped telescopic rod 96, the L-shaped telescopic rod 96 drives the knocking rod 99 to reset, the knocking rod 99 knocks the long rod 93, the long rod 93 vibrates and drives the V-shaped rod 94 to vibrate, thereby promoting the speed of the water scraped by the V-shaped rod 94 to flow into the discharge chute 4, and accelerating the efficiency of the V-shaped rod 94 to scrape the water on the surface of the protection inclined plate 3.
