A drainage channel 2 is fixedly mounted on the outer side of the harvesting bin 1. A data transmission device 3 is fixedly installed on the side wall of the harvesting bin 1. A first fixing frame 4 and a second fixing frame 17 are fixedly mounted on the inner wall of the harvesting bin 1. Four insertion holes 5 are symmetrically opened on the top of the first fixing frame 4, and pins 6 are inserted into the inner walls of each of the four insertion holes 5. A filter screen 7 is inserted into the top of each of the four pins 6, and four pins 6 are also inserted into the top of each of the four pins 6. The top of filter screen 28 is also connected to four pins 6, and filter plates 9 are inserted into the top of the four pins 6. A layer of gravel 10 is laid on the top of filter plates 9. A float valve 11 is provided in the inner cavity of the recovery chamber 1. An overflow pipe 12 is fixedly connected to the outer edge of the float valve 11. A heating pipe 13 is fixedly installed in the inner bottom of the recovery chamber 1. An activated carbon adsorption layer 18 is overlapped on the top of the fixing frame 27. Four bolts 20 are threadedly connected to the inner wall of the fixing frame 27. All four bolts 20 are threadedly connected to the inner wall of the ion exchange resin layer 19.
[0031] See Figure 4 and Figure 5A submersible pump 14 is fixedly installed at the bottom of the recycling bin 1. One end of a water pipe 15 is fixedly connected to the output end of the submersible pump 14, and a nozzle 16 is fixedly connected to the other end of the water pipe 15. The water pipe 15 is fixedly connected to the inner wall of the recycling bin 1. The water pipe 15 is made of an elastic and stretchable material, which allows rainwater collected in the inner cavity of the recycling bin 1 to be sprayed onto the green ground through the nozzle 16. Therefore, when it is necessary to water the greenery, there is no need to connect to an external water source, which improves the water utilization rate and reduces the loss of water resources.
[0032] See Figure 1 and Figure 4 A water quality sensor is fixedly installed in the recycling bin 1 and its inner cavity, and a liquid level sensor is fixedly installed on the outer edge of the float valve 11. The water quality sensor, liquid level sensor, data transmitter 3 and management terminal are electrically connected, so that the water quality and water level in the inner cavity of the recycling bin 1 can be monitored in real time using the water quality sensor and liquid level sensor, and the data can be sent to the management terminal through the wireless transmission technology of the data transmitter 3 to realize remote monitoring and operation.
[0033] See Figure 3 The filter screen 7, filter screen 8, and filter plate 9 are all fitted to the inner wall of the recycling bin 1. Filter screen 8 is located in the middle of filter screen 7 and filter plate 9. The density of filter screen 7 is less than that of filter screen 8, which ensures that rainwater that has penetrated through the gravel layer 10 into the inner cavity of the recycling bin 1 can be filtered by filter plate 9, filter screen 8, and filter screen 7 in sequence, thereby ensuring the thoroughness of rainwater filtration.
[0034] See Figure 2 and Figure 3 The filter plate 9 is made of stainless steel. The gravel layer 10 consists of several gravel of different sizes, which provides a certain load-bearing capacity and ensures that the gravel layer 10 will not easily collapse after being piled on top of the filter plate 9. The gravel layer 10 can perform preliminary filtration of rainwater, ensuring that larger impurities will not come into contact with the filter plate 9, filter screen 2 8 and filter screen 1 7, and thus will not easily cause blockage of the filter plate 9, filter screen 2 8 and filter screen 1 7.
[0035] See Figure 4 The overflow pipe 12 is fixedly installed on the inner wall of the recycling bin 1, so that it can be used in conjunction with the float valve 11 to control the water level and prevent overflow. The overflow pipe 12 can be connected to an external pipe, so that after the inner cavity of the recycling bin 1 is full of water, the treated rainwater can be transferred to another container for use.
[0036] See Figure 5The inner wall of the activated carbon adsorption layer 18 is symmetrically provided with four threaded holes. Four bolts 20 are threaded to the inner wall of the four threaded holes and threaded to the fixing frame 17. The outer sides of the activated carbon adsorption layer 18 and the ion exchange resin layer 19 are in contact with the inner wall of the recovery chamber 1, so that the activated carbon adsorption layer 18 can be stably installed on the top of the fixing frame 17 using the four bolts 20, and the ion exchange resin layer 19 can be stably set above the activated carbon adsorption layer 18. Thus, the activated carbon adsorption layer 18 can be used to further remove fine particles in the water, and the ion exchange resin layer 19 can remove heavy metal ions in the rainwater, improving the purification effect.
[0037] See Figure 5 An ultraviolet lamp is fixedly installed at the bottom of the activated carbon adsorption layer 18, and both the ultraviolet lamp and the heating tube 13 are connected to an external power source. The ultraviolet lamp can disinfect microorganisms in the collected rainwater, and the heating tube 13 can heat the rainwater in winter to prevent it from freezing.
[0038] Working Principle: When using this device, rainwater is first guided to the inner cavity of the collection chamber 1 via the diversion channel 2. It undergoes preliminary filtration through the gravel layer 10, ensuring that larger impurities do not come into contact with the filter plates 9, filter screens 8 and 7, thus preventing clogging. The rainwater is then further filtered through the gravel layer 10 using the filter plates 9, 8, and 7, ensuring thorough filtration. The activated carbon adsorption layer 18 further removes fine particles from the water, and the ion exchange resin layer 19 removes heavy metal ions, improving the purification effect. Ultraviolet lamps disinfect the collected rainwater, and the heating element 13... It can heat rainwater in winter to prevent freezing. It uses water quality and level sensors to monitor the water quality and level inside the recycling bin 1 in real time, and transmits the data to the management terminal via wireless transmission technology through the data transmitter 3 to achieve remote monitoring and operation. By driving the submersible pump 14, the rainwater filtered and purified inside the recycling bin 1 can be sprayed onto the green ground through the water pipe 15 and the nozzle 16. Therefore, when it is necessary to water the green area, there is no need to connect to an external water source, which improves the water utilization rate and reduces water resource loss. The overflow pipe 12 and the float valve 11 can be used to control the water level and prevent overflow. By connecting the overflow pipe 12 to the external pipeline, the treated rainwater can be transferred to another container for use after the recycling bin 1 is full.
