With reference to fig. 3 and 6, in order to drive the baffle 17 to gather more water, thereby further improving the driving effect on the power shaft 154, a magnet strip 174 for abutting the edge of the baffle 17 away from the hinge shaft 171 is fixedly arranged on the inner wall of the water storage tank 15, the whole baffle 17 is a metal strip for adsorbing the magnet strip 174, in this embodiment, the whole baffle 17 is made of stainless steel; in order to improve the sealing effect between the baffle plate 17 and the magnet strip 174, a sealing groove 175 is formed in the surface, facing the power pipe 152, of the magnet strip 174 along the length direction of the magnet strip 174, and a sealing strip 176 inserted into the sealing groove 175 is fixedly arranged on the baffle plate 17; in order to further drive the baffle 17 to gather more rainwater, a fixing groove 177 is formed in the sealing groove 175 and on the surface opposite to the sealing groove 175 along the length direction of the sealing groove 175, and rubber strips 178 for being inserted into the fixing groove 177 are arranged on the two surfaces, which are opposite to each other, of the sealing strip 176 along the length direction of the sealing strip 176; in order to facilitate the separation of the rubber strip 178 and the fixing groove 177, the cross section of the fixing groove 177 is set to be arc-shaped, and the rubber strip 178 is matched with the arc-shaped fixing groove 177.

As shown in fig. 3, in order to collect rainwater passing through the power pipe 152, the storage tank 18 is provided at an end of the power pipe 152 far from the storage tank 15, and the end of the power pipe 152 far from the storage tank 15 is communicated with the storage tank 18; in order to recycle rainwater collected in the storage tank 18, a drain pipe 181 penetrating and extending outside the road is provided on the bottom wall of the storage tank 18, and a drain switch 182 and a drain pump 183 are provided on the drain pipe 181, in this embodiment, the drain switch 182 is provided as a pneumatic butterfly valve.

The implementation principle of the multifunctional drainage system based on the highway engineering is as follows: rainwater collected in the drainage channel 1 can enter the water storage tank 15 through the flow guide pipe 151, the baffle 17 in the water storage tank 15 can play a role in blocking rainwater, the rainwater can be gathered on the baffle 17, after the rainwater is gathered to a certain degree, the baffle 17 drives the rubber strip 178 to be located in the fixing groove 177 to be separated due to the gravity of the rainwater, so that the sealing strip 176 is separated from the sealing groove 175, at the moment, the baffle 17 is separated from the magnet strip 174 to be adsorbed, a large amount of rainwater enters the power pipe 152, the plurality of power plates 155 drive the power shaft 154 to rotate due to the action of the water flow, the power shaft 154 drives the driving shaft 14 to rotate through the two bevel gears 16 which are mutually meshed, the driving shaft 14 can drive the cam 141 to rotate, the cam 141 drives the boss to resist the elastic force of the spring 142 to drive the reciprocating movement 126, the driving plate 126 can drive the scraper plates 122 on two sides to be located on the filter screen 11 to reciprocate, so that the driving plate 122 drives the bristles 123 to clean the filter screen 11, impurity after the clearance can be promoted to the stock chest 13 in, the torsional spring 173 can be resisted to baffle 17 this moment and the torsion resumes the normal position to collect the rainwater next time, prevent to pile up impurity on the filter screen 11 and cause the influence to the drainage of water drainage tank 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
