Description

Technical Field

[0001] The present application relates to the technical field of rainwater filtering devices, and in particular to a rainwater purification device suitable for sponge cities. Background Art

[0002] Sponge city is a new concept of urban rainwater management. Its main purpose is to enable the city to absorb and store rainwater like a sponge when the rainy season comes, and then release and use these water resources when needed, thereby achieving effective circulation and utilization of rainwater, which can effectively alleviate the impact of natural flood disasters caused by rainwater in the city; When cities use drainage pipes to absorb and store rainwater, the rainwater will carry a large amount of fallen leaves and other garbage into them, and gather together as the water flow converges, which can easily cause blockage in the drainage pipes. In addition, the long-term accumulation of fallen leaves or other garbage will cause corrosion and pollute the stored water resources, which will greatly affect the effective use of rainwater and may even breed a large number of bacteria or viruses and have an adverse effect on the city's sanitary environment.

[0003] Therefore, there is an urgent need for a rainwater filtering device to solve the defects of the above-mentioned existing sponge cities in absorbing and storing rainwater. Summary of the invention

[0004] The present application proposes a rainwater purification device suitable for sponge cities, which has the advantage of being able to effectively filter rainwater and prevent fallen leaves or other garbage carried therein from entering the reservoir. It is used to solve the problem that when cities use drainage pipes to absorb and store rainwater, rainwater will carry a large amount of fallen leaves and other garbage into them, and gather together with the convergence of water flow, which can easily cause blockage of drainage pipes. In addition, the long-term accumulation of fallen leaves or other garbage will cause corrosion and pollute the stored water resources, which will greatly affect the effective use of rainwater and may even breed a large number of bacteria or viruses and have an adverse effect on the city's sanitary environment.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a rainwater purification device suitable for sponge cities, comprising a straight cylinder whose top is flush with the ground and whose bottom is connected to a manhole, a filter assembly is arranged at the top of the inner cavity of the straight cylinder, and the top of the filter assembly is fixedly connected to the manhole cover arranged at the top of the straight cylinder through a linkage component, and at the same time, a water inlet pipe connected to the straight cylinder is arranged at the top of the left side of the outer surface of the straight cylinder, and the other end of the water inlet pipe is connected to the drainage pipeline, so that the collected rainwater passes through the straight cylinder and the manhole and enters the water storage tank for storage. The filter assembly comprises a filter basket movably sleeved on the bottom of the middle part of the inner cavity of the straight cylinder and provided with a filter mesh hole, so that rainwater, fallen leaves and other garbage entering the straight cylinder through the water inlet pipe can be filtered out, a connecting rod is fixedly installed on the top of the filter basket, and the filter basket is elastically connected to the top of the inner cavity of the straight cylinder through the connecting rod, and a second connecting groove for discharging the filtered fallen leaves and other garbage is opened in the middle of one side of the outer surface of the filter basket, and a first connecting groove located below the filter basket is opened in the middle of one side of the outer surface of the straight cylinder.

[0006] Furthermore, a sleeve is fixedly installed on the top of the inner cavity of the straight cylindrical member, and the top end of the connecting rod extends into the inner cavity of the sleeve, and forms a transmission connection with the sleeve through an elastic member movably sleeved on the top of the outer surface of the connecting rod, thereby forming an elastic connection between the filter basket and the straight cylindrical member, and forcing the filter basket to always remain in a state of returning to its initial position.

[0007] Furthermore, the linkage component includes a connecting shaft whose top of the outer surface is movably sleeved with the inside of the manhole cover, the inner wall of the connecting shaft is threadedly connected to the top of the outer surface of the sleeve, and the top of the connecting shaft is provided with a hexagonal slot, and when the manhole cover needs to be opened, the connecting shaft can be separated from the magnetic part by rotating the connecting shaft, and a magnetic part is fixedly installed on the top of the inner cavity of the connecting shaft, and a magnetic block with a magnetic pole opposite to that of the magnetic part is fixedly installed on the top of the connecting rod, wherein, for the setting of the magnetic part and the magnetic block on the top of the connecting rod, the suddenness of the magnetic connection and disconnection can be utilized to make the filter basket move downward only after it increases to a certain weight, thereby avoiding the elastic part changing a little bit, and after the weight of the filter basket increases a little, it moves downward a little, so that the first connecting groove and the second connecting groove cannot form a pouring action after overlapping, and the fallen leaves and other garbage filtered out of the filter basket cannot be completely discharged.

[0008] Furthermore, a baffle is fixedly installed on one side of the top of the filter basket and at a position corresponding to the second connecting groove, so that when the filter basket is in the initial position, the baffle can be used to block the first connecting groove on the straight cylinder to effectively prevent water from flowing out through the first connecting groove.

[0009] Furthermore, a group of connecting pipes connected to the drainage pipeline is provided on the left side of the inner cavity of the water inlet pipe opening, and the connecting pipes are eccentrically connected to the water inlet pipe opening, thereby forming a groove for depositing sludge at the bottom of the inner cavity of the water inlet pipe opening.

[0010] Furthermore, a sewage pipe is fixedly installed on the top of the left side of the inner wall of the straight cylinder, and the top of the sewage pipe is connected with the inner cavity of the water inlet pipe. A limiting rod is fixedly installed on the top of the left side of the inner wall of the filter basket. The top of the limiting rod extends to the inside of the sewage pipe and initially blocks the sewage pipe. When the limiting rod moves downward to the lower position with the filter basket, the sewage pipe is also connected to discharge the sludge deposited at the bottom of the inner cavity of the water inlet pipe.

[0011] Furthermore, a first tank body connected to the first connecting groove is provided at the bottom of the right side of the outer surface of the straight cylinder, and a second tank body connected to the bottom end of the sewage pipe is provided at the top of the left side of the outer surface of the straight cylinder. Therefore, under the action of the first tank body and the second tank body, fallen leaves and other garbage and sludge can be collected and cleaned together. Through holes are provided on the tops of the outer surfaces of the first tank body and the second tank body. At the same time, the setting of the through holes can allow the water vapor contained in the fallen leaves and other garbage and sludge to evaporate and be absorbed by the soil.

[0012] The beneficial effects of the present invention are as follows: The present application provides a rainwater purification device suitable for sponge cities. With respect to the setting of the filter component, as the amount of fallen leaves and other garbage filtered by the filter basket gradually increases, the flow rate of rainwater at its bottom gradually decreases, causing the rainwater to continuously accumulate in the filter basket and increasing its weight until the weight of the filter basket overcomes the magnetic force of the magnetic member and the magnetic block and moves downward. When the second connecting groove overlaps with the first connecting groove, a large amount of rainwater accumulated in the filter basket pours outward through the first connecting groove and the second connecting groove, and carries the fallen leaves and other garbage filtered by the filter basket out of the inner cavity of the straight cylinder, thereby effectively filtering the rainwater and preventing the fallen leaves or other garbage carried by the rainwater from entering the reservoir.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 , Figure 2 As shown, a rainwater purification device suitable for sponge cities includes a straight cylinder 1 whose top is flush with the ground and whose bottom is connected to a manhole. A filter assembly 5 is provided at the top of the inner cavity of the straight cylinder 1, and the top of the filter assembly 5 is fixedly connected to a manhole cover 6 arranged at the top of the straight cylinder 1 through a linkage component 7. At the same time, a water inlet pipe 8 connected thereto is provided at the top of the left side of the outer surface of the straight cylinder 1, and the other end of the water inlet pipe 8 is connected to a drainage pipeline, so that the collected rainwater passes through the straight cylinder 1 and the manhole and enters the water reservoir for storage, as shown in FIG. Figure 4 , Figure 5 As shown, the filter assembly 5 includes a filter basket 12 movably sleeved on the bottom of the middle part of the inner cavity of the straight cylinder 1 and provided with a filter mesh hole, so that rainwater, fallen leaves and other garbage entering the straight cylinder 1 through the water inlet pipe 8 can be filtered out, and a connecting rod 13 is fixedly installed on the top of the filter basket 12, and the filter basket 12 is elastically connected to the top of the inner cavity of the straight cylinder 1 through the connecting rod 13, and a second connecting groove 14 for discharging the filtered fallen leaves and other garbage is opened in the middle of one side of the outer surface of the filter basket 12, and a first connecting groove 9 located below the filter basket 12 is opened in the middle of one side of the outer surface of the straight cylinder 1. As the amount of fallen leaves and other garbage filtered by the filter basket 12 increases, the amount of rainwater flowing through the bottom of the filter basket 12 gradually decreases, causing the rainwater to continuously accumulate in the filter basket 12 and increasing its weight, until the weight of the filter basket 12 overcomes the elastic force of the linkage component 7 and moves downward, and when the second connecting groove 14 overlaps with the first connecting groove 9, a large amount of rainwater accumulated in the filter basket 12 pours outward through the first connecting groove 9 and the second connecting groove 14, and carries the fallen leaves and other garbage filtered by the filter basket 12 out of the inner cavity of the straight cylinder 1. When the rainwater collected in the filter basket 12 is poured out, its mass becomes lighter and automatically returns to the initial position under the elastic force of the linkage component 7, and the filtering operation of the rainwater continues.

[0017] like Figure 4 , Figure 6 As shown, in the present technical solution, a sleeve 10 is fixedly mounted on the top of the inner cavity of the straight cylinder 1, and the top end of the connecting rod 13 extends into the inner cavity of the sleeve 10, and forms a transmission connection with the sleeve 10 through an elastic member 19 movably sleeved on the top of the outer surface of the connecting rod 13, thereby forming an elastic connection between the filter basket 12 and the straight cylinder 1, and forcing the filter basket 12 to always remain in a state of returning to its initial position.

[0018] like Figure 6 As shown, in the present technical solution, the linkage component 7 includes a connecting shaft 17 whose top of the outer surface is movably sleeved with the inside of the manhole cover 6, the inner wall of the connecting shaft 17 is threadedly connected to the top of the outer surface of the sleeve 10, and the top of the connecting shaft 17 is provided with a hexagonal slot. When the manhole cover 6 needs to be opened, the connecting shaft 17 can be rotated to separate it from the magnetic member 18, and the magnetic member 18 is fixedly installed on the top of the inner cavity of the connecting shaft 17, and a magnetic block with a magnetic pole opposite to the magnetic member 18 is fixedly installed on the top of the connecting rod 13. Among them, for the arrangement of the magnetic member 18 and the magnetic block on the top of the connecting rod 13, the suddenness of magnetic connection and disconnection can be utilized to make the filter basket 12 move downward only after it increases to a certain weight, thereby avoiding the elastic member 19 from changing a little bit. After the weight of the filter basket 12 increases a little, it moves downward a little, so that the first connecting groove 9 and the second connecting groove 14 cannot form a pouring action after overlapping, and the fallen leaves and other garbage filtered on the filter basket 12 cannot be completely discharged.

[0019] like Figure 5 As shown, in the present technical solution, a baffle 15 is fixedly installed on one side of the top of the filter basket 12 and at a position corresponding to the second connecting groove 14, so that when the filter basket 12 is in the initial position, the baffle 15 can be used to block the first connecting groove 9 on the straight cylinder 1 to effectively prevent water from flowing out through the first connecting groove 9.

[0020] like Figure 1 , Figure 3 As shown, in the present technical solution, a group of connecting pipes connected to the drainage pipeline are provided on the left side of the inner cavity of the water inlet pipe port 8, and the connecting pipes are eccentrically connected to the water inlet pipe port 8, thereby forming a groove for depositing silt at the bottom of the inner cavity of the water inlet pipe port 8.

[0021] like Figure 1 , Figure 4 as well as Figure 5 As shown, in the present technical solution, a sewage pipe 11 is fixedly installed on the top of the left side of the inner wall of the straight cylinder 1, and the top of the sewage pipe 11 is connected to the inner cavity of the water inlet pipe 8, and a limiting rod 16 is fixedly installed on the top of the left side of the inner wall of the filter basket 12, and the top of the limiting rod 16 extends to the inside of the sewage pipe 11 and initially blocks the sewage pipe 11, and when the limiting rod 16 moves downward to the lower position with the filter basket 12, the sewage pipe 11 is also connected therewith to discharge the sludge deposited at the bottom of the inner cavity of the water inlet pipe 8.

[0022] like Figure 1 As shown, in the present technical scheme, a first tank body 2 connected to a first connecting groove 9 is provided at the bottom of the right side of the outer surface of the straight cylinder 1, and a second tank body 3 connected to the bottom end of a sewage pipe 11 is provided at the top of the left side of the outer surface of the straight cylinder 1, thereby, under the action of the first tank body 2 and the second tank body 3, fallen leaves and other garbage and sludge can be collected and cleaned together, and the tops of the outer surfaces of the first tank body 2 and the second tank body 3 are both provided with through holes 4, and at the same time, the setting of the through holes 4 can allow the water vapor contained in the fallen leaves and other garbage and sludge to evaporate and be absorbed by the soil.

[0023] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
