[0020] See also Figure 1-4A noise-reducing windshield for a road bridge comprises a windshield body 1, a fixed body 2 and a fixed base 3. A cavity is arranged inside the windshield body 1, and sound-absorbing cotton is fixedly installed in the cavity. A plurality of noise-reduction holes 5 are arranged on the front of the windshield body 1, and the noise-reduction holes 5 are communicated with the inner cavity of the windshield body 1. The sound-absorbing cotton is located on one side of the cavity of the windshield body 1 close to the noise-reduction holes 5. A plurality of rectangular grooves 4 are arranged on the upper half of the front of the windshield body 1, and the number of the rectangular grooves 4 is equal to the number of the noise-reduction holes 5. Each noise-reduction hole 5 is respectively located in each rectangular groove 4. The noise generated by the vehicle passes through the rectangular grooves 4 and the noise-reduction holes 5 and is absorbed by the sound-absorbing cotton. By arranging a plurality of rectangular grooves 4, and each noise-reduction hole 5 is located in each rectangular groove 4, the noise reduction can be satisfied while the noise reduction is satisfied. In order to better protect the sound insulation cotton in the cavity of the windshield body 1, the bottom of the fixed body 2 is fixedly connected to the top of the fixed base 3, and a windshield card slot 11 is arranged inside the fixed body 2, and the windshield card slot 11 runs through the left side and the right side of the fixed body 2 and the top and the bottom of the fixed body 2. A windshield slot 10 is arranged on the top of the fixed base 3, and the windshield slot 10 runs through the left side and the right side of the fixed base 3. The width of the windshield slot 10 is equal to the width of the windshield card slot 11, and the positions of the windshield slot 10 and the windshield card slot 11 correspond. The bottom of the windshield body 1 can be inserted into the windshield card slot 11 and the windshield slot 10, and the thickness of the windshield body 1 corresponds to the width of the windshield slot 10 and the windshield card slot 11. A plurality of through holes 12 are provided on both sides of the fixed body 2, and the through holes 12 pass through the front and back of the fixed body 2. A plurality of round holes corresponding to the through holes 12 on the fixed body 2 are provided on both sides of the windshield body 1, and the round holes pass through the front and back of the windshield body 1. When the edge line of the windshield body 1 is located at the center line of the windshield card slot 11 in the fixed body 2, the through holes 12 on the fixed body 2 are aligned with the round holes on the windshield body 1, and bolts are inserted and installed in the through holes 12 on the fixed body 2 and the round holes on the windshield body 1. A plurality of threaded holes 13 passing through the top and bottom of the fixed base 3 are provided. By placing the fixed base 3 and the fixed body 2 at the positions to be fixed, and using bolts to pass through the threaded holes 13 on the fixed base 3, because The height of the fixed base 3 and the fixed body 2 is relatively low, which makes it more convenient to move and install. After the fixed base 3 is fixed, the windshield body 1 is inserted into the windshield card slot 11 on the fixed body 2 and the windshield slot 10 on the top of the fixed base 3. At this time, the windshield body 1 can be initially fixed. Finally, the round hole on the windshield body 1 corresponds to the through hole 12 on the fixed body 2, and then the bolts are inserted and tightened. The other side of the windshield body 1 is inserted into another fixed body 2 and the fixed base 3, and the bolts are tightened. The fixation is completed by analogy. The entire installation process does not require the windshield of the entire height to be fixed, which reduces the difficulty of installation and makes it easier to install. Two support columns 9 are fixedly installed on the top of the windshield body 1.The two support columns 9 are respectively located at the left and right sides of the top of the windshield body 1. The outer surfaces of the two support columns 9 are movably sleeved with movable baffles 7. A buffer pad is fixedly installed on the top of the movable baffle 7. By installing the movable baffle 7 on the top of the windshield body 1, when encountering severe weather such as heavy rain, hail, and snow, the movable baffle 7 is impacted by downward pressure and will move downward. At this time, under the action of the buffer spring 6, the elastic force of the buffer spring 6 itself can be used to buffer the movable baffle 7, thereby reducing the pressure on the windshield body 1, and the windshield body 1 can be effectively protected, thereby improving the safety of use and service life. When the top of the movable baffle 7 is subjected to impact force, the buffer pad can buffer the impact object, reduce the noise hitting the top of the movable baffle 7, and reduce the damage of the movable baffle 7. The width of the movable baffle 7 in the front-to-back direction is greater than the thickness of the windshield body 1, and the length of the movable baffle 7 in the left-right direction is greater than the length of the top of the windshield body 1. It can ensure that the movable baffle 7 will move the top of the windshield body 1 While the windshield body 1 is completely covered, it will not affect the splicing work between the windshield bodies 1. The tops of the two support columns 9 can be detachably installed with limit plates 8. The limit plates 8 can limit the movable baffle 7 to prevent the movable baffle 7 from being separated from the support column 9 under the elastic force of the buffer spring 6. The limit plates 8 and the support column 9 are threadedly plugged. Through the threaded connection, the limit plates 8 can be removed from the support column 9, so as to facilitate the cleaning and replacement of the support column 9. The outer surfaces of the two support columns 9 are movably sleeved with buffer springs 6, and the buffer springs 6 are located below the movable baffles 7. By installing the movable baffles 7 on the top of the windshield body 1, when encountering severe weather such as heavy rain, hail, and heavy snow, the movable baffles 7 will be impacted by downward pressure and will move downward. At this time, under the action of the buffer springs 6, the elastic force of the buffer springs 6 can be used to buffer the movable baffles 7, thereby reducing the pressure on the windshield body 1, and effectively protecting the windshield body 1, thereby improving the safety of use and service life.
[0021] Working principle: When using, first determine the installation position, place the fixed base 3 and the fixed body 2 at the position where they need to be fixed, and use bolts to pass through the threaded holes 13 on the fixed base 3. Because the height of the fixed base 3 and the fixed body 2 is relatively low, it is more convenient to move and install. After the fixed base 3 is fixed, insert the windshield body 1 into the windshield card slot 11 on the fixed body 2 and the windshield slot 10 on the top of the fixed base 3. At this time, the windshield body 1 can be initially fixed. Finally, make the round hole on the windshield body 1 correspond to the through hole 12 on the fixed body 2, and then use The bolts are inserted and tightened, and the other side of the windshield body 1 is inserted into another fixed body 2 and a fixed base 3, and the bolts are screwed on, and the fixation is completed by analogy. The noise generated by the vehicle during use passes through the rectangular groove 4 and the noise reduction hole 5 and is absorbed by the sound-absorbing cotton. When encountering severe weather such as heavy rain, hail, and snow, the movable baffle 7 is impacted by the downward pressure and will move downward. At this time, under the action of the buffer spring 6, the elastic force of the buffer spring 6 itself can be used to buffer the movable baffle 7, thereby reducing the pressure on the windshield body 1, and effectively protecting the windshield body 1, thereby improving the safety of use and service life.
