[0022] The embodiment of the utility model will be described in further detail below in combination with the drawings and examples.
[0023] Example 1:
[0024] As shown in the accompanying Figure 1 to the accompanying Figure 5 As shown:

[0027] Among them, the circular through slot inside bottom of water blocking layer 105 is fixedly connected and seted up the piston cylinder 109 of cylindrical structure, and the top of piston cylinder 109 is seted up the water inlet of one-way valve structure, and the top middle of piston cylinder 109 is seted up through type's circular through slot structure, and the piston cylinder 109 and water blocking layer 105 between seted up sealing structure, the bottom end of sliding frame 106 is fixedly connected and seted up the piston plate 110 of round plate structure, and the outer wall of piston plate 110 and the inner wall of piston cylinder 109 are pasted, and the side of piston cylinder 109 is seted up the water outlet 111 of one-way valve structure, and the water outlet 111 and the drainage pipeline of outside are communicated.
[0028] The specific use and role of the embodiment are as follows:
[0029] The fixed plate 1 is installed above the expansion joint, two groups of collecting grooves 107 and sliding frames 106 are arranged at the two ends of the fixed plate 1 respectively, so as to avoid blocking the path, so that the two groups of side plates 101 are in contact with the inner walls of the expansion joint respectively, and the water retaining layer 105 is fixedly installed at the bottom of the two groups of side plates 101 through bolts, so that the two sides of the water retaining layer 105 are in contact with the two side walls of the expansion joint respectively. When it rains heavily, the rainwater entering the expansion joint can be directly blocked by the water retaining layer 105 and collected in the middle of the inner side of the water retaining layer 105, and part of the rainwater will be collected in the collecting groove 107 first. If the rain continues to increase, the water amount in the collecting groove 107 will increase, and the weight of the collecting groove 107 will further increase, so as to press the sliding frame 106 through the two groups of collecting grooves 107 and slide downward synchronously.
