DETAILED DESCRIPTION

[0021] The following will be combined with 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 making creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 17 As shown, an urban rainwater collection, purification and storage device comprises a water reservoir 1, a plurality of PP water storage modules 6 are arranged inside the water reservoir 1, an inlet pipe 2 and an outlet pipe 4 are arranged on both sides of the water reservoir 1, and the upper end of the inlet pipe 2 is connected to the lower end of the collection well 3; A manhole cover 5 is installed at the upper end of the collection well 3, and a plurality of drain ports 501 are arranged in the middle of the manhole cover 5. Mounting frames 9 and adjusting slide rails 301 are installed on both sides of the inner wall of the collection well 3. Filter components 8 for preliminary purification of rainwater are installed between the mounting frames 9, and supporting components 7 for supporting the filter components 8 are arranged between the adjusting slide rails 301.

[0023] A plurality of PP water storage modules 6 are arranged inside the water reservoir 1. With the support of the PP water storage modules 6, the water reservoir 1 can be arranged below the ground, thereby reducing the footprint of the water storage device. The collection well 3 can be arranged on the urban road surface. When there is a lot of rain on the road surface, the rainwater will fall from the drain port 501 into the collection well 3, and then be purified by the filter component 8. Then the rainwater will enter the water reservoir 1 through the water inlet pipe 2 to realize the water storage operation. When taking water, a pumping device is used to connect the water outlet pipe 4 to realize the extraction and reuse of rainwater.

[0024] In this embodiment, the filter assembly 8 includes a placement frame 801, a filter net 802 is arranged inside the placement frame 801, movable grooves 803 are opened on both sides of the placement frame 801, and a movable frame 8031 ​​is movably installed inside each movable groove 803 through an auxiliary spring 8032. Slide frames 804 are respectively installed at both ends of the movable frame 8031. An arc-shaped slide groove 901 is opened on the surface of the placement frame 9, and the slide frame 804 is slidably connected to the adjacent arc-shaped slide groove 901.

[0025] A limit hole 8041 is provided on the surface of the slide frame 804 , and a limit guide rail 8042 is provided at the lower side of the limit hole 8041 .

[0026] In the present application, an insert rod 8055 is slidably installed inside the limiting through hole 8041 and the limiting guide rail 8042. A swing groove 8056 is provided on the surface of the insert rod 8055. A swing seat 8057 is movably provided inside the swing groove 8056. A tension spring 8058 is fixedly installed on the outside of the swing seat 8057.

[0027] In the specific configuration, both ends of the placement frame 801 are respectively provided with turning grooves 805 , inside of the turning grooves 805 a turning shaft 8051 is rotatably installed, and each turning shaft 8051 is provided with a pressure guide plate 8052 .

[0028] It should be noted that an extension seat 8053 is installed at the lower end of the pressure guide plate 8052, and a movable connecting plate 8054 is rotatably installed at the upper end of the insertion rod 8055. The interior of the extension seat 8053 is rotatably connected to the upper end of the movable connecting plate 8054.

[0029] During the rainwater collection process, debris will fall down together. When the debris falls on the upper surface of the filter 802, the rainwater at the current position will accumulate on it. The support rod 701 is rotated so that the placement frame 801 is turned to the side where the rainwater accumulates, and the filter 802 is tilted, so that the debris on the surface of the filter 802 falls down and is discharged into the collection frame 302 on the corresponding side to separate the rainwater from the debris. In order to realize the swinging of both sides of the placement frame 801, the pressure guide plate 8052 on the pressure side will be pressed by the corresponding rainwater, so that the pressure guide plate 8052 drives the flip shaft 8051 to flip outward. During the flipping process, the expansion seat 8053 will press down the movable connecting plate 8054 and make the insertion rod 8055 move downward inside the limiting through hole 8041. When the insertion rod 8055 moves downward, the tension spring 8058 fixedly installed on the outer side of the swing seat 8057 can pull the support rod 701 to move in the downward direction, adjust the flipping center of the placement frame 801, and realize the placement frame. 801 swings to the other side, and this swing can ensure that the debris on the surface of the filter 802 will fall into the collection frame 302 on the corresponding side, avoiding the problem that the placement frame 801 cannot be reset after being flipped, resulting in the other side not being able to be cleaned in time. The above structure can enable the present application to clean the debris attached to the surface of the filter 802, avoiding the situation where excessive accumulation of debris on the surface of the filter 802 leads to a decrease in water storage efficiency and rainwater overflow, wherein the present application does not require additional electric drive, and will only clean when blocked, thereby facilitating use and installation by personnel.

[0030] In this embodiment, side slide rails 806 are respectively provided on both sides of the placement frame 801, and sliding seats 8061 are slidably installed inside the side slide rails 806. A fixed seat 8062 is fixedly installed on the upper end of the sliding seat 8061, and a triangular shovel plate 8063 is fixedly installed between the fixed seats 8062 on both sides. The bottom of the triangular shovel plate 8063 is in contact with the filter screen 802 and the upper surface of the placement frame 801.

[0031] In order to improve the efficiency of cleaning debris, the slide seat 8061 on the side slide rail 806 will actively move toward the lower position during the flipping and tilting of the placement frame 801, and the shape setting of the triangular shovel plate 8063 during the movement can make one side be impacted by rainwater while the other side is cleaning the debris, thereby assisting the cleaning, thereby achieving efficient cleaning. In conjunction with the placement frame 801 in this application that can swing on both sides, the triangular shovel plate 8063 can reciprocate to process the debris on the surface of the filter net 802 to avoid the residue of debris.

[0032] In this embodiment, the support assembly 7 includes a support rod 701, and movable platforms 702 are respectively installed at both ends of the support rod 701. The movable platforms 702 at both ends are respectively slidably installed inside the corresponding adjustment rails 301, and auxiliary pulleys 703 are provided on the upper and lower surfaces of the movable platforms 702.

[0033] Among them, grooves 704 are respectively opened on both sides of the rod body of the support rod 701, and two swivels 705 are slidably installed inside each groove 704. A connecting seat 706 is set on the outside of each swivel 705, and each connecting seat 706 is connected to the corresponding tension spring 8058.

[0034] In order to enable the support rod 701 to change the flipping center of the placement frame 801, when one side of the placement frame 801 is flipped, the swing seat 8057 descends and pulls the tension spring 8058, so that the tension of the tension spring 8058 on the current side on the connecting seat 706 is greater than the pulling of the other side, so that the support rod 701 cooperates with the moving platform 702 to move inside the adjustment slide rail 301, and moves to the side where the placement frame 801 flips downward, so that the placement frame 801 will immediately flip to the other side after discharging the debris, and continuously clean until there is no debris to cause blockage, and then restore to the parallel state of the placement frame 801 until the next round of blockage.

[0035] In this embodiment, collection frames 302 are hung on both sides of the collection well 3 through hanging rods 303 , and a guide groove 304 is provided below the collection frame 302 .

[0036] The hanging rod 303 provided on the upper side of the collecting frame 302 can facilitate operators to extract or install the collecting frame 302, so as to uniformly process the collected debris. The collecting frame 302 can further drain rainwater on the debris and discharge it from the water inlet pipe 2 along the guide groove 304.

[0037] The working principle of this urban rainwater collection, purification and storage device: When in use, rainwater is first collected from the drain port 501. During the rainwater collection process, debris will fall together. When the debris falls on the upper surface of the filter 802, the rainwater at the current position will accumulate on it. The support rod 701 is rotated so that the placement frame 801 is turned to the side where the rainwater accumulates, and the filter 802 is tilted, so that the debris on the surface of the filter 802 falls and is discharged into the collection frame 302 on the corresponding side. During this process, the pressure guide plate 8052 on the pressure side will be pressed by the corresponding rainwater, so that the pressure guide plate 8052 drives the flip shaft 8051 to flip outward. During the flipping process, the extension seat 8053 will press down the movable connecting plate 8054 and make the insertion rod 8055 move downward inside the limit through hole 8041. When the insertion rod 8055 moves downward, the retracting spring 8058 fixedly installed on the outer side of the swing seat 8057 can be used to pull the support rod 701 to move in the downward direction, adjust the flip center of the placement frame 801, and realize the swing of the placement frame 801 to the other side. During the swinging process, the slide seat 8061 on the side slide rail 806 will actively move to the lower position, and during the movement, the shape of the triangular shovel plate 8063 can be used to clean the debris on one side while the other side is impacted by rain to assist in cleaning, and the placement frame 801 can swing on both sides, so that the triangular shovel plate 8063 can reciprocate to process the debris on the surface of the filter screen 802 to avoid the residue of the debris; The filtered and purified rainwater will enter the water reservoir 1 through the water inlet pipe 2 to realize the water storage operation. When water is needed, a pumping device is used to connect the water outlet pipe 4 to realize the extraction and reuse of rainwater.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
