When the rainwater flowing into the linear drainage ditch passes through the connecting pipe, part of the rainwater will be treated by the filtering device and enter the purified water collection pipe downward, and finally be stored in the purified water transfer tank, increasing the rainwater treatment efficiency while reducing the sewage storage capacity and increasing the purified water storage capacity, thereby increasing the rainwater collection utilization rate.

[0004] In the above prior art, the rainwater collection utilization rate is increased. However, when the rainwater is precipitated in the sewage well, due to being mixed with a large amount of impurities and mud, it will cause the problem of blockage of the rainwater conveying pipe during the conveying process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1, reference Figure 1-2 A rainwater collection device for construction sites comprises a drainage well 4, a cover body 1 and rainwater delivery pipes 5 connected at both sides of the drainage well 4: a slope 17 with a middle portion protruding upward is arranged at the bottom of the drainage well 4, a sleeve 11 is arranged at the top of the slope 17 through a connecting piece, the connecting piece comprises a support rod 13, a sphere 14 and a groove 15, the groove 15 is opened at the bottom position of the slope 17, the sphere 14 is movably arranged in the groove 15, and the support rod 13 is vertically connected between the sphere 14 and the bottom of the sleeve 11.

[0027] A plurality of blades 12 are evenly and vertically installed on the outer side of the sleeve 11 , and the blades 12 are located between the two rainwater conveying pipes 5 , and a spacer assembly 16 is dragged at the bottom of the blades 12 .

[0028] Reference Figure 4-5 The spacer bar assembly 16 includes a scraper unit 161, a first slot 162, a second slot 163 and a connecting rod 164. The two end surfaces of each scraper unit 161 are provided with a first slot 162 and a second slot 163 that are interconnected. The first slot 162 is located near the inner side of the scraper unit 161, and the width of the first slot 162 is greater than the width of the second slot 163. The two scraper units 161 are connected by a connecting rod 164, and the connecting rod 164 is arranged in an "I" shape. The two ends of the connecting rod 164 are located on different inner sides of the first slot 162 and the second slot 163. The bottom of the scraper unit 161 is in contact with the inclined surface 17, and the connecting rod 164 can move in the vertical direction.

[0029] During the use of the drainage well 4, as rainwater continues to flow in, impurities in the rainwater will form mud and accumulate inside the drainage well 4. In this way, the cover 1 needs to be opened and the mud inside the drainage well 4 needs to be cleaned, which makes maintenance more cumbersome.

[0030] To this end, a casing 11 is provided inside the drainage well 4. When rainwater rapidly enters the drainage well 4 from the rainwater delivery pipe 5, it will drive the blades 12 outside the casing 11 to rotate. The bottom inclined surface 17 of the drainage well 4 is conical, so that the mud will stay relatively concentrated at the lower end position of the inclined surface 17. A partition strip assembly 16 is provided at the bottom of the blade 12. The partition strip assembly 16 is composed of a number of scraping unit 161. Adjacent two scraping units 161 are connected through the first slot 162, the second slot 163 on both sides and the connecting rod 164 in the shape of "I". The distance between the outermost scraping unit 161 and the inner wall of the drainage well 4 is two centimeters. Since adjacent two scraping units 161 can be staggered up and down and displaced, in view of the complex situation in the drainage well 4, the inclined surface 17 is uneven. In this case, it is ensured that the scraping unit 161 contacts the inclined surface 17 to a greater extent. These uneven areas are prone to accumulate mud. This setting can well ensure that the scraping unit 161 fits the inclined surface 17 and ensure the contact effect with the mud. With the surging water flow, the mud is output from the rainwater delivery pipe 5 along with the water flow.

[0031] Example 2, refer to Figure 2-3 , the difference between this embodiment and Embodiment 1 is that a foam float 7 floats in the drainage well 4. A hollow rod 10 is provided at the bottom of the foam float 7. The bottom of the hollow rod 10 extends into the lower casing 11, and the hollow rod 10 can move up and down in the casing 11. When the foam float 7 is in the lowest position, there is a gap between its bottom and the lower casing 11.

[0032] Water baffle plates 9 are provided at the end positions of the rainwater delivery pipe 5 through rotating shafts. The water baffle plate 9 is connected with a connecting rope 8 at the upper end inside the drainage well 4, and the other end of the connecting rope 8 is fixed outside the foam float 7.

[0033] When rainwater enters the drainage well 4 from the rainwater delivery pipe 5 and the water flow is relatively stable, the mud in the drainage well 4 cannot be effectively lifted, so the effect of taking away the mud will decrease.

[0034] For this reason, a foam float ball 7 is arranged in the drainage well 4. When the foam float ball 7 is in the initial position, it floats on the water surface, so that the upper part of the sleeve 11 does not contact the bottom of the foam float ball 7, and the water level remains stable. When rainwater comes into the drainage well 4, the turbulent water flow will cause the foam float ball 7 to float up and down. During the small-range floating process, the foam float ball 7 drives the straightened connecting rope 8 to move together. In this way, the water baffle 9 at the end position of the two rainwater conveying pipes 5 realizes a certain angle of flipping. The water baffle 9 is horizontal in the initial state. During the flipping process, the water baffle 9 will form a certain obstruction to the flow of rainwater. When the rainwater hits the water baffle 9, a turbulent flow can be formed in the drainage well 4, and the turbulent flow will further lift the mud, effectively helping the mud to be discharged from the drainage well 4.

[0035] Example 3, refer to Figure 6-7 , the difference between this embodiment and Embodiment 1 and Embodiment 2 is that a clamping seat 6 is detachably installed at the bottom of the cover body 1, and the outer diameter size of the clamping seat 6 matches the size of the upper edge of the drainage well 4, and a cavity 18 is arranged inside the clamping seat 6.

[0036] An air inlet hole 19 communicating with the inside of the drainage well 4 is opened at the bottom position of the cavity 18. A circular pipe 20 is vertically arranged at the outer ring position of the air inlet hole 19. A cover body 24 is fixed outside the circular pipe 20. A reagent storage chamber 21 in the shape of a ring is arranged at the middle position inside the cover body 24. A through hole 22 is arranged at the top of the cover body 24, and the cover body 24 is detachably installed at the lower end of the cover body 1.

[0037] An annular baffle 23 is arranged at the upper part of the cover body 24. The bottom of the baffle 23 extends into the reagent in the reagent storage chamber 21, and a gap is arranged between the bottom of the baffle 23 and the bottom of the reagent storage chamber 21.

[0038] A first communication pipe 2 and a second communication pipe 3 are respectively arranged on the cover body 1. The bottom of the first communication pipe 2 extends to the inside of the drainage well 4. The upper end of the first communication pipe 2 is communicated with a gas supply device through a hose, and a one-way valve is arranged inside the first communication pipe 2 to allow gas to smoothly enter the inside of the drainage well 4. The bottom of the second communication pipe 3 extends into the cavity 18, and the upper port of the second communication pipe 3 is communicated with a gas storage chamber through a hose.

[0039] The inside of the drainage well 4 is usually in a sealed state. The sealed state will cause rainwater to generate methane and hydrogen sulfide gases, increasing the danger of the drainage well 4. However, the drainage well 4 cannot be directly communicated with the outside, because this will cause the stench of the mixed rainwater to directly enter the air.

[0040] For this purpose, a cavity 18 is provided in the card holder 6. The cavity 18 is internally connected to the inside of the drainage well 4 through an air inlet hole 19. The generated gas enters the cavity 18 from the air inlet hole 19, and the gas enters the reagent storage chamber 21 along the round tube 20. Activated carbon particles are placed in the reagent storage chamber 21. The activated carbon particles can adsorb hydrogen sulfide gas by means of the adsorption sites on their outer surfaces, thereby treating hydrogen sulfide gas. At the same time, the bottom of the baffle 23 extends into the activated carbon particles, and methane is adsorbed while removing hydrogen sulfide gas.

[0041] At the same time, in order to suppress the generation of harmful gases to a certain extent, air is passed into the drainage well 4 through the first connecting pipe 2, and a one-way valve is provided in the first connecting pipe 2 so that the gas will not overflow outward. Passing in air can not only suppress the generation of hydrogen sulfide gas, but also assist in squeezing the generated harmful gases into the cavity 18.

[0042] The working principle of this device is as follows: During the use of the drainage well 4, as rainwater continuously flows in, impurities in the rainwater will form mud and accumulate inside the drainage well 4. In this case, it is necessary to open the cover body 1 and clean the mud inside the drainage well 4, and the maintenance is rather cumbersome.

[0043] For this purpose, a sleeve 11 is provided inside the drainage well 4. When rainwater quickly enters the drainage well 4 from the rainwater delivery pipe 5, it will drive the blades 12 outside the sleeve 11 to rotate. The bottom slope 17 of the drainage well 4 is conical. In this way, the mud will stay relatively concentrated at the lower end position of the slope 17. A partition component 16 is provided at the bottom of the blade 12. The partition component 16 is composed of several scraping unit 161. Adjacent two scraping unit 161 are connected through the first slot hole 162, the second slot hole 163 and the "I"-shaped connecting rod 164 on both sides. The distance between the outermost scraping unit 161 and the inner wall of the drainage well 4 is two centimeters. Since adjacent two scraping unit 161 can be staggered up and down and displaced, in view of the complex situation in the drainage well 4, the slope 17 is uneven. In this case, it is ensured that the scraping unit 161 contacts the slope 17 to a greater extent. These uneven areas are prone to accumulate mud. This setting can well ensure that the scraping unit 161 fits the slope 17 and ensures the contact effect with the mud. With the surging water flow, the mud is output from the rainwater delivery pipe 5 along with the water flow.

[0044] When the rainwater enters the drainage well 4 from the rainwater delivery pipe 5 and the water flow is relatively stable, the mud in the drainage well 4 cannot be effectively lifted, and the effect of taking away the mud will decrease.

[0045] To this end, a foam float ball 7 is arranged in the drainage well 4. When the foam float ball 7 is in the initial position, it floats on the water surface, such that the upper part of the sleeve 11 does not contact the bottom of the foam float ball 7, and the water level remains stable. When rainwater enters the drainage well 4, the turbulent water flow causes the foam float ball 7 to float up and down. During the small-range floating process, the foam float ball 7 drives the taut connecting rope 8 to move together. In this way, the water baffle 9 at the end positions of the two rainwater conveying pipes 5 realizes a certain-angle flip. The water baffle 9 is horizontal in the initial state. During the flipping process, the water baffle 9 will form a certain obstruction to the flow of rainwater. When the rainwater impacts the water baffle 9, a turbulent flow can be formed in the drainage well 4. The turbulent flow will further lift the mud, effectively helping the mud to be discharged from the drainage well 4.

[0046] The inside of the drainage well 4 is usually in a sealed state. The sealed state will cause the rainwater to produce methane and hydrogen sulfide gases, increasing the danger of the drainage well 4. However, the drainage well 4 cannot be directly connected to the outside, because this will cause the stench of the rainwater to directly enter the air.

[0047] To this end, a cavity 18 is arranged in the card seat 6. The cavity 18 is connected to the inside of the drainage well 4 through an air inlet hole 19. The generated gas enters the cavity 18 through the air inlet hole 19. The gas flows along the round pipe 20 into the reagent storage chamber 21. Activated carbon particles are stored in the reagent storage chamber 21. The activated carbon particles can adsorb hydrogen sulfide gas by means of the adsorption sites on their outer surfaces, thereby treating hydrogen sulfide gas. At the same time, the bottom of the baffle 23 extends into the activated carbon particles, adsorbing methane while removing hydrogen sulfide gas.

[0048] At the same time, in order to suppress the generation of harmful gases to a certain extent, air is passed into the drainage well 4 through the first connecting pipe 2. A one-way valve is arranged in the first connecting pipe 2, and the gas will not overflow outward. Passing in air can not only suppress the generation of hydrogen sulfide gas, but also assist in squeezing the generated harmful gases into the cavity 18.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
