[0034] It should be noted here that: when there is rainwater outside and the amount of rain is small, the rainwater collected on the conical rain collecting hopper 2 passes through each group of filter holes 602 and flows to the inside of the first annular cavity 302 through transmission, and the rainwater flowing into the first annular cavity 302 is transported outward through the first delivery pipe 304.

[0039] Preferably, the filter assembly includes an annular baffle 601 fixed to the upper end of the conical rain collecting hopper 2, and the annular baffle 601 is provided with a plurality of filter holes 602 for assisting rainwater to pass through and filtering foreign matter;

[0040] It should be noted here that: in the process of collecting and transporting rainwater, the collected rainwater passes through each group of filter holes 602, thereby filtering the collected rainwater and avoiding clogging of the first transport pipe 304 and the second transport pipe 305 by foreign matter when in use.

[0042] It should be noted here that: the driving shaft 702 and the driving disk 703 at one end of the driving shaft 702 are rotated through the driving assembly. During the rotation of the driving disk 703, the conical rain collecting bucket 2 is driven to rotate through the connection and transmission action of each group of jacks 901 and each group of transmission rods 902.

[0044] It should be noted that the driving motor 802 on the U-shaped frame 801 facilitates the driving operation of the driving shaft 702;

[0045] It is worth noting here that a battery and a controller are provided inside the fixed cylinder 701, and the battery, the drive motor 802 and the controller are electrically connected. During the entire control process, the battery, the drive motor 802 and the controller serve as conventional drive components, power supply components and control components, and are used as prior art in this application. Their working principles and operating methods will not be elaborated on here.

[0046] Preferably, the collecting assembly includes a collecting cover 1001 fixed to the outside of the cylindrical base 101, a supporting frame 102 fixed to the lower end of the collecting cover 1001, and a material blocking plate 1002 for blocking foreign matter that slides out is fixed to the upper end of the collecting cover 1001;

[0047] It should be noted here that: through transmission, the conical rain collecting hopper 2 is forced to rotate. During the rotation of the conical rain collecting hopper 2, the foreign matter on the side of the annular baffle 601 on the conical rain collecting hopper 2 moves outward along the radial direction of the conical rain collecting hopper 2 under the action of centrifugal force, collides with the inner side of the baffle plate 1002, and falls into the interior of the collection cover 1001 for collection, thereby avoiding the presence of foreign matter after filtration to block the filter hole 602 and affect the efficiency of subsequent rainwater transportation.

[0048] In this scheme: an environmental protection engineering rainwater recycling device includes the following steps:

[0049] In the process of collecting, acquiring and transporting rainwater by using the rainwater recycling device in environmental protection projects, each group of support frames 102 is fixed to the designated use position through the installation of bolts. When rainwater is not collected after installation, the elastic support component supports the conical rain collecting bucket 2 with elastic force, so that the conical rain collecting bucket 2 is in an initial non-dropped state (see Figure 7 ), at this time, the fixed cylinder 701 abuts against the inner side of the annular baffle 601 and blocks each group of filter holes 602, and the annular blocking plate 306 at the lower end of the conical rain collecting hopper 2 blocks the first annular cavity 302;

[0050] When there is rain outside and the amount of rain is small, the falling rainwater is collected on the conical rain collecting hopper 2. As the rainwater is collected, the weight of the conical rain collecting hopper 2 increases and it moves downward. During the downward movement of the conical rain collecting hopper 2, the groups of filter holes 602 on the annular baffle 601 are connected to the interior of the first annular cavity 302. At this time, the rainwater collected on the conical rain collecting hopper 2 passes through the groups of filter holes 602 and flows into the interior of the first annular cavity 302. The rainwater flowing into the first annular cavity 302 is transported outward through the first transport pipe 304 (see FIG. 2 ). Figure 8), to achieve the purpose of rainwater collection and transportation, and in the process of transportation, because the diameter of the first delivery pipe 304 is small, the smaller diameter means a smaller cross-sectional area, which can maintain a relatively appropriate speed when transporting rainwater, ensuring that rainwater can flow normally in the pipeline, avoiding the phenomenon of slow flow or even stagnation of water flow, and can timely transport rainwater to the storage cylinder, thereby improving the operating efficiency of the rainwater recycling device. When the amount of rainwater outside increases, the first delivery pipe 304 transports less rainwater collected on the conical rain collecting bucket 2 than the conical rain collecting bucket 2. As the amount of rainwater on the rain collecting hopper 2 increases, the amount of rainwater collected on the conical rain collecting hopper 2 increases, and under the action of gravity, the conical rain collecting hopper 2 further moves downward. During the further downward movement of the conical rain collecting hopper 2, the filter holes 602 on the annular baffle 601 are connected to the interior of the second annular cavity 303. At this time, the rainwater collected on the conical rain collecting hopper 2 passes through the filter holes 602 and flows into the interior of the second annular cavity 303. The rainwater flowing into the second annular cavity 303 is transported outward through the second transport pipe 305 (see FIG. Fig. 9 ), the purpose of rainwater collection and transportation is achieved, and in the process of transportation, because the diameter of the second delivery pipe 305 is large, the effect of transporting the collected rainwater is guaranteed, and the probability of overflow of part of the collected rainwater due to low transportation efficiency is reduced;

[0051] In the process of collecting and transporting rainwater, the collected rainwater passes through each group of filter holes 602 to achieve the effect of filtering the collected rainwater, thereby avoiding clogging of the first transport pipe 304 and the second transport pipe 305 by foreign matter during use. When the foreign matter blocked on the side of the annular baffle 601 needs to be separated and collected after filtering, the drive shaft 702 and the drive disk 703 at one end of the drive shaft 702 are rotated through the driving assembly. During the rotation of the drive disk 703, the conical rain collecting hopper 2 is driven to rotate by the connection and transmission action of each group of jacks 901 and each group of transmission rods 902. During the rotation of the conical rain collecting hopper 2, the foreign matter on the side of the annular baffle 601 on the conical rain collecting hopper 2 moves outward along the radial direction of the conical rain collecting hopper 2 under the action of centrifugal force, and collides with the inner side of the baffle plate 1002 and falls into the inner part of the collection cover 1001 for collection (see FIG. 1 ). Fig.10 ) to prevent the presence of foreign matter after filtration from blocking the filter hole 602 and affecting the efficiency of subsequent rainwater transportation.
