[0020] Furthermore, the water storage part of the intelligent drainage and recycling system of the present invention is also provided with a water outlet connected to the municipal drainage channel.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] On the one hand, the intelligent drainage and recycling system described in the present invention can overall control and dispatch the operation of the intelligent drainage and recycling system through a control system, transport water to the water storage part through the water collection part and the water collection pipe, and then reuse the purified water to the pool and the water spraying device as needed through the water purification module. When the water flow is too large, the pool can also contribute part of the water storage capacity, and can also collect water into the water storage part through the overflow port B.

[0023] On the other hand, the intelligent drainage and recycling system described in the present invention can be used to completely replace the existing green belts, which is convenient for construction.

[0024] In addition, the drainage unit can replace the existing drainage outlet device as a whole. According to the specific shape and size of the existing drainage well cover, the shape and size of the outer ring of the cover body described in this application are processed to ensure that the cover body can match the existing drainage well, and the existing drainage well cover can be conveniently replaced with the cover body described in this application. Then, the drainage pipe described in this application is installed as a whole at the original downpipe drainage outlet, and the original underground drainage pipeline does not need to be changed, which is convenient for construction. If necessary, only a new filter storage box needs to be set up near the drainage outlet.

[0025] Secondly, the intelligent drainage pipe for municipal engineering described in the present invention can automatically change the number of water inlet holes according to the size of the water flow rate. Specifically, the water wheel driven by the water flow in the pipe body cooperates with the lifting and lowering of the gear rack mechanism to control the inner circle of the double-layer structure of the cover body, so that the outer grate rises and the inner grate falls at the same time, thereby opening the water inlet holes between the inner grate and the outer grate, thereby increasing the drainage volume of the drainage unit.

[0026] In addition, the drainage volume can be further increased through the overflow port A. On the contrary, when the water flow of the drainage unit decreases and does not cover the overflow port A, the water flow can pass through the water channel on the filter plate A, so that the water flow is concentrated on the two parts of the filter plate A, thereby reversing the water wheel, causing the inner layer grate and the outer layer grate to move toward each other, closing the water inlet hole between the inner and outer layer grate, and the cover body automatically returns to the initial state.

[0027] The alarm and flow detection device equipped in the drainage unit described in the present invention can also intelligently mark the location, thereby effectively predicting and preventing urban waterlogging and protecting the lives and property of residents.

The height of the overflow port A112 is located at 1 / 2~2 / 3 of the height difference between the outer ring 201 and the rotating shaft A104.

[0058] In this embodiment, the storage box 401 is placed in an underground pit, and a handle is provided on the storage box 401 .

[0059] The specific working principle of the intelligent drainage and recycling system of the present invention is as follows:

[0060] On the one hand, the present application can overall control and dispatch the operation of the intelligent drainage and recycling system through the control system, transport water to the water storage part 30 through the water collection part 20 and the water collection pipe 60, and then reuse the purified water to the water pool 40 and the water spraying device 11 as needed through the water purification module 31. When the water flow is too large, the water pool 40 can also contribute part of the water storage capacity, and can also collect water into the water storage part 30 through the overflow port B41.

[0061] On the other hand, during the specific use of the water collecting part 20, the normal use state of the drainage unit is as follows: Fig. 9 As shown, water flows into the drainage unit only from the drainage surface 2021 and the water inlet hole 206 on the outer grate 204. At this time, due to the different thicknesses of the water channel 3104 and its filter plate A310, the water flow on the filter plate A310 tends to concentrate toward the second part 3103, so that the water wheel 106 does not rotate; after flowing through the B section pipe 102 and the C section pipe 103, the water flows into the municipal drainage system.

[0062] When the water flow rate gradually increases, and water accumulates on the filter plate A310 and overflows the overflow port A112, the water flows directly from the overflow port A112 to the pipe section B 102, and the water flow hits the blades 1061 of the water wheel 106, and the grooves 1062 strengthen the force on the blades 1061, so that the water wheel 106 starts to rotate counterclockwise, thereby driving the gears A107 and B108 to rotate. At this time, the state of the drainage unit is as follows: Figure 3 As shown, the counterclockwise rotation of gear A107 drives rack C111 to move downward, thereby pulling the inner layer grate 205 downward; at the same time, gear A107 also drives rack B110 to move upward, thereby pulling filter plate B320 through movable connecting rod 3203, thereby opening part A 3201 and part B 3202, increasing the flow of water. At this time, gear B108 also rotates counterclockwise, driving rack A109 to move upward, thereby driving outer layer grate 204 to move upward, opening all water inlet holes 206 on inner layer grate 205 and outer layer grate 204, and increasing the flow of water. At the same time, shaft B105 also drives flexible screw 402 to transport the filtered material to the filtered material cleaning box through the bevel gear mechanism.

[0063] When the water flow gradually decreases, there is no more water flowing through the overflow port A112, and the water flow tends to concentrate toward the second part 3103. The water wheel 106 starts to rotate clockwise, and the gear A107 and the gear B108 also rotate clockwise at the same time. The rack A109, the rack B110, and the rack C111 all start to reset until the drainage unit returns to the state as shown in the figure. Figure 8 Normal use status shown.

[0064] The water collecting part 20 of the present invention can automatically and intelligently adapt to a suitable state according to the required drainage volume through the above process without any additional energy source, and is easy to use and has good effect.

[0065] The above-mentioned specific implementation methods further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
