[0026] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for a rainwater harvesting and irrigation device used in urban and rural planning:

[0027] A rainwater harvesting and irrigation device for urban and rural planning includes: a box body 1, an orifice plate 2, a sealing device 3, a shell 31, an electric push rod 32, a baffle 33, a mixing device 4, a servo motor 41, a stirring rod 42, a scraper 43, a chemical dispensing box 44, a conduit 45, an extraction device 5, a pump body 51, a vertical pipe 52, an opening 53, a side box 6, a water level sensor 7, a first cover 8, a second cover 9, a third cover 10, a support plate 11, a filter screen 12, a filter sand layer 13, and a sand and gravel layer 14. The box body 1 has a circular structure, and an orifice plate 2 is fixedly connected to the upper part of the inner wall. Rectangular openings are machined on both sides of the orifice plate 2. The mixing device 4 is installed inside the box body 1. The mixing device 4 consists of a servo motor 41, a stirring rod 42, a scraper 43, and a chemical dispensing box 44. The system consists of a tank 44 and a conduit 45. A servo motor 41 is positioned above the orifice plate 2. The output end of the servo motor 41 is fixedly connected to a stirring rod 42, and the upper part of the stirring rod 42 is rotatably connected to the inner wall of the orifice plate 2 via a sealed bearing. A scraper 43 is fixedly connected to the end of the stirring rod 42, and the outer wall of the scraper 43 is in contact with the inner wall of the tank 1. A medicine dispensing box 44 is fixedly connected to the upper side of one side of the outer wall of the tank 1. The bottom of the medicine dispensing box 44 is connected to a conduit 45, and the conduit 45 has a curved structure. The other end of the conduit 45 is connected to the upper side of the tank 1 near the medicine dispensing box 44. The servo motor 41 drives the stirring rod 42 and the scraper 43 to mix the water source and fertilizer or medicine, which improves the processing efficiency and ensures the uniformity of mixing.

[0028] A sealing device 3 is provided on the top of the orifice plate 2. The sealing device 3 consists of a housing 31, an electric push rod 32, and a baffle 33. Two housings 31 are provided and are fixedly connected to the top two sides of the orifice plate 2 respectively. The top of both housings 31 is inclined. An electric push rod 32 is fixedly connected inside both housings 31. A baffle 33 is fixedly connected to the output end of both electric push rods 32. The outer wall of the two baffles 33 is respectively in contact with the inner wall of the orifice plate 2 and the housing 31. The electric push rod 32 can change the position of the baffle 33 so that the orifice plate 2 can be sealed and closed by the baffle 33.

[0029] Both baffles 33 have sealing gaskets fixedly connected to their outer walls. The sealing gaskets can improve the sealing effect between the baffles 33 and the housing 31 and the orifice plate 2, thereby preventing rainwater from entering the interior of the housing 31 and causing damage to the electric push rod 32.

[0030] A side box 6 is fixedly connected to the side of the box 1 away from the medicine box 44. An extraction device 5 is installed inside the side box 6. The extraction device 5 consists of a pump body 51, a vertical pipe 52 and an opening 53. The pump body 51 is fixedly connected to the bottom of the inner wall of the side box 6. The output end of the pump body 51 is connected to the vertical pipe 52. An opening 53 is machined on the side of the box 1 near the side box 6. The pump body 51 extracts the irrigation water source from the inside of the box 1 through the vertical pipe 52. The water source inside the box 1 enters the inside of the side box 6 through the opening 53.

[0031] A water level sensor 7 is installed on one side of the inside of the side box 6. A first cover 8 is fixedly connected to the top of the side box 6, and the inner wall of the first cover 8 is fixedly connected to the upper part of the outer wall of the vertical pipe 52. A second cover 9 is fixedly connected to the top of the orifice plate 2, and a third cover 10 is fixedly connected to the top of the medicine box 44. The water level sensor 7 can monitor the amount of water remaining inside the box 1 in real time. When the water is insufficient, it can transmit a signal to an external control device, thereby shutting down the pump 51 to avoid overheating and damage to the pump 51 due to insufficient water. Sealing gaskets are installed under the first cover 8, the second cover 9, and the third cover 10 to ensure the sealing performance of the first cover 8, the second cover 9, and the third cover 10 during use.

[0032] A support plate 11 is fixedly connected to the upper inner wall of the housing 1, and a filter screen 12 is fixedly connected to the inner wall of the support plate 11. A filter sand layer 13 is laid on top of the support plate 11, and a gravel layer 14 is laid on top of the filter sand layer 13. The gravel layer 14 can filter and block fallen leaves and impurities in the rainwater, and the filter sand layer 13 can further filter and block the rainwater, filtering out small particles such as soil in the rainwater. Finally, the rainwater is finely filtered through the filter screen 12, which can prevent impurities from accumulating inside the housing 1 during long-term use, thereby affecting the quality of use of the rainwater collection and irrigation device used for urban and rural planning.

[0033] Specifically, this application should include an external control device. When the water level sensor 7 detects insufficient water in the tank 1, it should automatically shut down the pump 51 to prevent overheating and damage. The external control device can control the operating status of the electrical equipment inside the rainwater harvesting and irrigation device for urban and rural planning. Its connection method, operating principle, and operation method are all existing known technologies, so they will not be elaborated on here. Those skilled in the art should interpret them broadly. The models of the electric push rod 32, servo motor 41, water level sensor 7, and pump 51 are not limited, as long as they meet the usage requirements. Furthermore, the electric push rod 32 and servo motor 41 should be waterproofed to prevent water ingress and short circuits. The specific measures are not limited, as long as they meet the usage requirements.

[0034] Specific implementation steps:

[0035] When using the rainwater harvesting and irrigation device for urban and rural planning, it needs to be pre-buried in the ground. When it rains, the rainwater is filtered through the gravel layer 14, the sand filter layer 13, and the filter screen 12 before entering the lower part of the tank 1. When fertilization or pesticide application is needed during irrigation, the operator opens the pesticide / pesticide tank 44 and injects the fertilizer or pesticide into the tank 1 through the conduit 45. Then, the servo motor 41 is activated, which drives the stirring rod 42 and the scraper 43 to rotate, thus facilitating the mixing of water and fertilizer. Alternatively, the medicine can be mixed. After mixing, the servo motor 41 is turned off and the pump body 51 is turned on. At this time, the pump body 51 can draw water from the side box 6 through the vertical pipe 52, and then watering can be carried out. The water from the box 1 continuously enters the side box 6 through the opening 53, thereby ensuring the continuity of watering. When the water in the side box 6 drops below the detection point of the water level sensor 7, the water level sensor 7 can send the detection signal to the external control device. At this time, the external control device can turn off the pump body 51, thereby ensuring the safe use of the pump body 51.

[0036] In summary, this rainwater harvesting irrigation device for urban and rural planning, which uses a dispensing tank and conduit to place the fertilizer or pesticide inside the main body, and then utilizes a servo motor to drive a stirring rod and scraper for mixing, ensures that the fertilizer or pesticide is thoroughly mixed with the irrigation water. During irrigation, the fertilizer or pesticide can reach the plant roots along with the irrigation water, thus reducing the workload of workers, shortening the overall working time, and facilitating operation. The electric push rod, by changing the position of the baffle at the top of the orifice plate, allows the device to be closed when rainwater harvesting is not in use, thereby preventing water from entering the main body. The rainwater collection and irrigation device for urban and rural planning has improved features such as the ability to mix irrigation water with pesticides or fertilizers, reduce the evaporation rate of the water inside the tank on sunny days, and filter the rainwater to increase its storage time. The inclusion of sand and gravel layers, filter sand layers, support plates, and filter screens filters the collected rainwater, preventing external impurities such as fallen leaves from entering the tank and causing blockages. This invention effectively solves the problems and shortcomings of existing devices.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
