In this form, when the guide plate 8 swings with the change of the water level, the part of the guide surface 802 near the first collecting structure 7 is moderately higher than the opening of the first receiving groove 701, so as to facilitate the garbage and sundries to fall into the first receiving groove 701, thereby ensuring the receiving effect.

[0080] Further, as shown in Figure 1 , the first collecting structure 7 and the guide plate 8 extend along the width direction of the river body 10, so as to ensure the cleaning effect on the water surface.

[0081] In a possible implementation, as shown in Figure 1 and Figure 7 , the collecting unit further includes a second collecting structure 9. The second collecting structure 9 is fixedly arranged on the end of the guide plate 8 near the first receiving groove 701. The second collecting structure 9 is located on the wall surface of the guide plate 8 away from the guide surface 802. The second collecting structure 9 has a second receiving groove with an opening facing the second floating member 801. When the end of the guide plate 8 away from the first receiving groove 701 is higher than the end near the first receiving groove 701, the side of the guide plate 8 away from the guide surface 802 can form a guide surface. The second collecting structure 9 can still collect the garbage and sundries on the water surface, thereby effectively improving the collection reliability of the collecting unit.

[0082] Specifically, when the gate 2 is in the lifting state, the end of the guide plate 8 away from the first receiving groove 701 is lower than the end near the first receiving groove 701. At this time, the garbage and sundries mainly enter the first collecting structure 7 along the guide surface 802. When the gate 2 is in the blocking state, the water surface is in the water storage state, and the water level is higher than the first receiving groove 701. At this time, the second collecting structure 9 can play a collecting role.

[0083] Further, as shown in Figure 7As shown, the wall surface of the guide plate 8 away from the guide surface 802 is provided with a plurality of grooves 804, which extend along the direction of the water flow. Such a form of the groove 804 can not only play a guiding role on the water flow and sundries, reduce the swing of the guide plate 8 itself, but also make the sundries and garbage smoothly enter the second collection structure 9. In addition, the groove 804 can effectively reduce the weight of the guide plate 8, so that the guide plate 8 can more easily float on the water surface.

[0084] In a possible implementation, as shown in Figure 6 and Figure 7 shown, the first collection structure 7 is fixedly provided with a first connecting structure 702 on the wall surface away from the gate 2, and the guide plate 8 is provided with a second connecting structure 803 at one end close to the gate 2. The first connecting structure 702 is hinged with the second connecting structure 803. Such a connection form does not need to arrange a connecting structure on the gate 2, but can be connected with the second connecting structure 803 of the guide plate 8 through the first connecting structure 702 on the first collection structure 7. The guide plate 8 can be pre-assembled with the first collection structure 7. In addition, the guide plate 8 can be disassembled together with the first collection structure 7, which is more convenient for disassembly, assembly, maintenance and repair.

[0085] Specifically, as shown in Figure 6 shown, the first connecting structure 702 includes a rotating seat 7021, a rotating groove 7022, and a fixed rod 7023. The rotating seat 7021 is fixed on the wall surface of the first collection structure 7 away from the gate 2. The rotating seat 7021 is provided with a plurality of rotating grooves 7022 on the side away from the first collection structure 7. The plurality of rotating grooves 7022 are arranged at intervals along the extension direction of the first collection structure 7. The second connecting structure 803 is arranged on the wall surface of the guide plate 8 away from the guide surface 802, and is a hinged seat. A plurality of second connecting structures 803 are arranged at intervals along the extension direction of the first collection structure 7. Each second connecting structure 803 can be inserted into the corresponding rotating groove 7022. The first collection structure 7 has a first hinge hole that passes through each rotating groove 7022. Each second connecting structure 803 is provided with a second hinge hole. The fixed rod 7023 passes through the first hinge hole and the second hinge hole alternately arranged to hinge them.

[0086] In a possible implementation, the groove bottom of the first receiving groove 701 and the second receiving groove is respectively provided with a first flow-through hole and a second flow-through hole 901. The structure is simple and reliable, and can make the water flow smoothly out of the first receiving groove 701 and the second receiving groove.

[0087] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
