[0002] Traffic noise refers to the sound generated by various means of transportation during their driving process that interferes with people's normal life, such as tire friction, airplane roar, ship whistle, train rumble, car horn and brake sound, as well as car and motorcycle motor sound. Sound barriers are mainly used for sound insulation and noise reduction on roads, expressways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to a wall structure set up on the side of railways and highways to reduce the impact of traffic noise on nearby residents. Sound insulation walls are also called sound barriers. A facility is inserted between the sound source and the receiver to make the sound wave propagation have a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. Such a facility is called a sound barrier.

[0003] According to the Chinese patent with the announcement number: CN211036746U, a double-sided sound-absorbing barrier for a highway includes a vertically arranged sound-absorbing straight plate, a plurality of support columns are vertically arranged at intervals along the length direction on the upper surface of the sound-absorbing straight plate, a plurality of support columns are fixedly connected to mounting seats along the direction of the sound-absorbing straight plate at the top ends, planting tubes are installed at intervals on both sides of the mounting seat along the length direction, and plants are planted in the planting tubes.

[0004] In the above scheme, sound absorption is carried out by using sound-absorbing straight plates and curved sound insulation plates, which results in the following disadvantages: when the sound-absorbing barrier is in use, dust, dirt and other debris on the sound-absorbing straight plates cannot be processed, resulting in reduced sound absorption performance. Utility Model Content

[0013] Beneficial effects:

[0014] 1. During use, the water tank is used to collect rainwater, which is beneficial for saving water resources. It is also beneficial for removing dust, dirt and other debris on the sound-absorbing board body to maintain the sound absorption performance of the sound-absorbing board body, thereby effectively reducing traffic noise and ensuring the comfort of the surrounding environment and residents;

[0015] Second, during use, the brush helps the nozzle to move along with the guide rail, so that the surface of the sound-absorbing board can be cleaned, dirt and dust can be removed more thoroughly, and the cleaning efficiency can be improved. The slide groove and the sliding block can help limit the nozzle to prevent the nozzle from deviating, thereby improving the stability of the nozzle during movement;

[0016] 3. During use, the filter screen helps to block impurities or debris, preventing them from entering the water tank, so that the connecting pipe and the delivery hose will not be blocked, and at the same time it helps to improve the cleanliness of the water quality.
