[0010] The beneficial effects of this utility model are:

[0011] This utility model relates to an urban road rainwater harvesting, purification, and utilization system. Rainwater is filtered by a filter cartridge inside the rainwater trough before entering and being stored in a collection chamber. A water pump and drain pipe can drain the water from the collection chamber. Connecting holes allow adjacent collection chambers to be interconnected, thus maintaining a consistent liquid level in different collection chambers during periods of heavy rainfall. This prevents localized overload from causing insufficient storage in the collection chamber, achieving the goal of convenient rainwater storage and purification. It is beneficial for water conservation and utilization, solving the problem of existing devices being inconvenient for rainwater storage and causing rainwater waste. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown: A rainwater collection, purification and utilization system for urban roads includes a road 1, and a manhole cover groove 2 is formed on the surface of the road 1. A rainwater collection system is installed below the manhole cover trough 2. The rainwater collection system includes a rainwater trough 3 on the bottom surface of the manhole cover trough 2. Collection chambers 4 are symmetrically arranged on both sides of the rainwater trough 3. Water inlet holes 5 are opened in the middle of both sides of the rainwater trough 3 and are connected to the collection chambers 4. A water pump 9 is fixedly installed on the bottom surface of the collection chamber 4. A drain pipe 10 is fixedly connected to the output end of the water pump 9. Adjacent collection chambers 4 are connected to each other through connecting holes 6. A filter cylinder 8 is installed inside the water inlet hole 5. An annular plate is fixedly installed on the end face of the filter cylinder 8. The annular plate is fixed to the side wall of the rainwater trough 3 by screws. A water outlet hole 7 is opened on the top surface of the collection chamber 4. The drain pipe 10 is fixedly fitted inside the water outlet hole 7. The rainwater passing through the rainwater trough 3 is filtered by the filter cylinder 8. Since the filter cylinder is set, the quality of rainwater collection can be improved. The filtered rainwater enters the collection chamber 4 and is stored. The water inside the collection chamber 4 can be discharged by the water pump 9 and the drain pipe 10.

[0020] like Figure 3 As shown, the connecting hole 6 allows the adjacent collection chambers 4 to be interconnected. This ensures that when there is a large amount of rainwater, the liquid level in the collection chambers 4 at different locations remains consistent, preventing the situation where excessive local rainwater makes it impossible to store rainwater inside the collection chamber 4. This achieves the purpose of facilitating the storage and purification of rainwater, which is beneficial for saving water resources and solves the problem that existing devices are not convenient for storing rainwater, resulting in the waste of rainwater.

[0021] like Figure 3 , Figure 4 As shown: To facilitate maintenance of the rainwater trough by staff, a ladder 13 is fixedly installed on the side wall of the rainwater trough 3. A filter plate 11 and a manhole cover 12 are movably fitted on the bottom surface of the manhole cover trough 2. The manhole cover 12 is located above the filter plate 11. The surface of the filter plate 11 has filter holes, and the surface of the manhole cover 12 has a rectangular filter groove. The ladder 13 allows staff to enter the rainwater trough 3 and clean it. The manhole cover 12 and the filter plate 11 can prevent pedestrians from accidentally falling into the rainwater trough 3, and can also perform preliminary filtration of impurities in the rainwater.

[0022] Working principle and usage process of this utility model:

[0023] In use, rainwater on the road is first filtered through the manhole cover 12 and the filter plate 11. Then, the rainwater flows into the rainwater trough 3 through the manhole cover groove 2. When the water level inside the rainwater trough 3 exceeds the inlet hole 5, the rainwater inside will be filtered by the filter cylinder 8 and then enter the collection chamber 4 for storage. The water pump 9 can be started to discharge the water inside the collection chamber 4 through the drain pipe 10. The connecting hole 6 can connect the collection chambers 4 in adjacent positions, so that when there is a lot of rainwater, the liquid level height of the collection chambers 4 in different positions can be kept consistent.

[0024] The rainwater collection, purification and utilization system of this utility model sets up a rainwater trough and a collection chamber, and installs a water pump and a drain pipe inside the collection chamber to drain the water inside the collection chamber. This avoids the situation where there is too much rainwater in a local area and the collection chamber cannot be stored. It achieves the purpose of facilitating the storage and purification of rainwater, which is conducive to saving water resources and solves the problem that existing devices are not convenient for storing rainwater and cause rainwater waste.

[0025] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.

[0026] Apart from the technical features described in the specification, all other technical features are known to those skilled in the art.
