Description

Technical Field

[0001] The invention relates to the technical field of rainwater recycling, in particular to a rainwater recycling device in a municipal garden area. Background Art

[0002] Municipal gardens refer to the general term for planning, design, construction, maintenance and other work related to gardens in urban construction. They involve the greening, beautification and ecological construction of the city, aiming to improve the living environment of urban residents and the overall image of the city. Rainwater recycling devices are being used more and more widely in municipal garden areas, aiming to improve the utilization rate of rainwater resources, reduce dependence on tap water, and reduce the pressure on urban drainage systems.

[0003] At present, the existing rainwater recycling and utilization devices usually store rainwater in a reservoir through the cooperation of a sewer and a pipe. When the garden needs to be irrigated, the rainwater collected in the reservoir can be directly used for irrigation. However, the existing sewers usually simply use grilles to intercept the garbage washed down by rainwater. There are many dead branches and leaves in the garden, and there are also some packaging bags. These garbage will block the grilles of the sewers, especially in some low-lying areas in the garden. The water flow is relatively large, and the blocked grilles will cause the speed of rainwater flowing into the sewer to slow down, which will cause the low-lying areas of the garden to be easily flooded.

DETAILED DESCRIPTION

[0039] 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.

[0040] See also Figure 1-11 In the embodiment of the present invention, a rainwater recycling device for a municipal garden area includes a sewer 1, a dirt intercepting mechanism 2, a filtering mechanism 3, a collecting bin 4, a folding mechanism 5 and a switching mechanism 6;

[0041] Discharge ports are provided at the tops of the two opposite sides of the sewer well 1. The sewer well 1 is connected to the water storage tank by a pipe so that rainwater flowing into the sewer well 1 flows into the water storage tank through the pipe. A dirt blocking mechanism 2 is provided at the top of the sewer well 1. The dirt blocking mechanism 2 can slide up and down at the top of the sewer well 1 to filter larger garbage in the rainwater. A filtering mechanism 3 is provided inside the sewer well 1 to filter rainwater and small garbage flowing into the sewer well 1. The filtering mechanism 3 includes a conveyor belt 31 rolling inside the sewer well 1. The conveyor belt 31 is a mesh structure. Collection bins 4 are fixedly connected on both sides of the well 1, which are used to collect small pieces of garbage that flow into the well 1 with rainwater. A feed port is penetrated through the collection bin 4 at the corresponding discharge port. A floating plate 41 is provided inside the collection bin 4, and a trash basket 42 is provided on the top surface of the floating plate 41. Folding mechanisms 5 are provided at both ends of the conveyor belt 31 for supporting the conveyor belt 31 and for folding the two ends of the conveyor belt 31 to facilitate taking out the trash basket 42 from the inside of the collection bin 4 at the corresponding position. A switching mechanism 6 is provided on one side of the well 1 for changing the rotation direction of the conveyor belt 31.

[0042] Specifically, first, the sewer well 1 and the two collecting bins 4 are buried underground, and the tops of the sewer well 1 and the collecting bins 4 are flush with the ground. Then, a certain amount of water is poured into the two collecting bins 4. When it rains heavily, especially in the low-lying areas of the garden, the flow rate of rainwater into the sewer well 1 is relatively large, and the flowing rainwater will drive a large amount of garbage such as branches and packaging bags to block the water inlet of the sewer well 1. Therefore, the garbage blocking mechanism 2 can be separated from the top of the sewer well 1 by moving it up and down, so that the rainwater can flow into the sewer well 1 quickly. The up and down movement of the garbage blocking mechanism 2 will block the larger garbage in the flowing rainwater and prevent the larger garbage from entering the sewer well 1, thereby realizing the first filtration of the flowing rainwater. Although there is no large piece of garbage in the rainwater after the first filtration, there will still be a large number of small pieces. Garbage, so the rainwater that has been filtered for the first time flows into the conveyor belt 31 in the sewer well 1, and through the rolling of the conveyor belt 31, and because the conveyor belt 31 is a mesh structure, the rainwater that flows into the sewer well 1 is filtered for the second time through the conveyor belt 31, and the small pieces of garbage in the rainwater fall into the garbage basket 42 at the rolling direction of the conveyor belt 31 under the rolling of the conveyor belt 31. When the garbage in the garbage basket 42 becomes more and more and reaches a certain weight, it will drive the switching mechanism 6 to start, so that the rolling direction of the conveyor belt 31 is changed. At this time, the conveyor belt 31 transports the small pieces of garbage on its surface to the garbage basket 42 in another collection bin 4. When the garbage in the garbage basket 42 needs to be taken out, the staff can open the top cover of the collection bin 4, and then use tools to take out the garbage basket 42 here from the collection bin 4 at the corresponding position, according to Figure 3It can be seen that in order to facilitate the conveyor belt 31 to convey small pieces of garbage to the collection bin 4, the two ends of the conveyor belt 31 are respectively located inside the collection bin 4 at corresponding positions. Therefore, when taking out the garbage basket 42, the end of the conveyor belt 31 here is rotated and retracted into the discharge port at the corresponding position under the action of the folding mechanism 5 at the corresponding position, and then the staff can smoothly take out the garbage basket 42 from the inside of the collection bin 4 at the corresponding position and pour out the garbage inside it, and then put it into the collection bin 4. When putting in the garbage basket 42, the folded part of the conveyor belt 31 begins to slowly return to its original position, and then the staff can take out the garbage in the other garbage basket 42. The device can lift up large pieces of garbage through the up and down reciprocating movement of the garbage blocking mechanism 2, so that rainwater can flow from the garbage blocking mechanism 2 and the sewer 1. The gaps between the conveyor belt 31 and the waste container 31 can flow into the manhole 1, thereby preventing large pieces of garbage from blocking the water inlet of the manhole 1 and affecting the flow rate of rainwater, thereby avoiding flooding in low-lying areas of the garden, and by making the conveyor belt 31 a mesh structure, the rainwater can be filtered for a second time to prevent small pieces of garbage from accumulating in the pipe between the manhole 1 and the reservoir, and by the rolling of the conveyor belt 31, the small pieces of garbage can be transported to one of the garbage baskets 42 to prevent small pieces of garbage on the surface of the conveyor belt 31 from blocking the speed at which rainwater penetrates the conveyor belt 31, and the rolling direction of the conveyor belt 31 can be automatically adjusted according to the overall weight of the garbage basket 42 through the switching mechanism 6, so as to automatically transport small pieces of garbage to the other garbage basket 42, thereby avoiding excessive garbage in the garbage basket 42 from clogging the feed port of the collection bin 4.

[0043] Embodiment 1

[0044] like Figure 7 As shown, in this embodiment, two upper and lower symmetrical support blocks 11 are fixedly connected to the two opposite side surfaces inside the sewer 1, and the dirt-blocking mechanism 2 includes a fixed frame 21 sliding inside the sewer 1, a grille 22 is hinged on one side of the top surface of the fixed frame 21, and a connecting block 23 is fixedly connected to the bottom surface of the fixed frame 21 corresponding to the support block 11, and a reciprocating screw 24 that penetrates and screws with the connecting block 23 at the corresponding position is rotatably connected between the two support blocks 11 at relative positions, and a plurality of baffles 25 are fixedly connected at equal intervals at the four edges of the bottom surface of the fixed frame 21, and a round rod 26 is rotatably connected between the two opposite side surfaces inside the sewer 1, and the bottom end of the reciprocating screw 24 penetrates the support block 11 at the corresponding position and is fixedly connected with a bevel gear 27, and both ends of the outer wall of the round rod 26 are fixedly connected with a bevel gear 3 28 meshing with the bevel gear 27 at the corresponding position, and a protective shell 12 for covering the bevel gear 27 and the bevel gear 3 28 at the corresponding position is fixedly connected to the two opposite side surfaces inside the sewer 1.

[0045] In this embodiment, the rotation of two reciprocating screw rods 24 can enable the fixed frame 21 to drive the grille 22 to move back and forth up and down at the water inlet of the sewer 1, so that the garbage on the top surface of the grille 22 can be lifted up, so that rainwater flows into the interior of the sewer 1 from the gap between the grille 22 and the sewer 1, and under the action of multiple baffles 25, large pieces of garbage can be prevented from passing through the gap between the grille 22 and the sewer 1, thereby effectively preventing large pieces of garbage from entering the sewer 1.

Since the two sprocket wheels 1 34 are engaged with the chain 32 at the corresponding positions, the rotating sprocket wheel 1 34 can make the conveyor belt 31 roll between the two folding mechanisms 5, so that the conveyor belt 31 can transport small pieces of garbage on its surface to the inside of one of the garbage baskets 42. Moreover, the conveyor belt 31 is a mesh structure, which can realize secondary filtration of rainwater entering the sewer well 1.

[0049] according to Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, a fixed block 1 is fixedly connected to one side of the sewer 1, a rotating shaft 1 passes through the top surface of the fixed block 1, and both ends of the outer wall of the rotating shaft 1 are fixedly connected to a bevel gear 14, one end of the round rod 26 passes through the sewer 1 and is fixedly connected to a bevel gear 4 29 meshing with the bevel gear 14 at the corresponding position, and another bevel gear 14 meshes with a bevel gear 6 for transmission.

[0050] In this embodiment, the drive of the motor 39 can make the bevel gear six drive the two bevel gears 14 to rotate, and the rotating bevel gear 1 14 can make the bevel gear 4 29 drive the round rod 26 to rotate, so that the bevel gear 3 28 can drive the bevel gear 2 27 to rotate. Therefore, the drive of the motor 39 can make the two reciprocating screws 24 rotate.

[0051] Embodiment 3

[0052] like Fig. 9 and Figure 8 As shown, in this embodiment, both sides of the two opposite sides inside the sewer 1 are fixedly connected with connecting plates 16, and the bottom end of one side of the connecting plate 16 is rotatably connected to a roller 161 that is abutted against the chain 32 at the corresponding position. The folding mechanism 5 includes two symmetrical rotating rods 51 located inside the conveyor belt 31, and both ends of the outer walls of the rotating rods 51 are fixedly connected to sprocket wheels 52 that are engaged with the chain 32 at the corresponding position. Both ends of the two rotating rods 51 near the middle of the conveyor belt 31 penetrate the sewer 1, and both ends of the outer walls of the two rotating rods 51 near the conveyor belt 31 penetrate and rotate with sleeves 53 that penetrate and rotate with the sewer 1. The outer wall of the sleeve 53 is fixedly connected to a connecting plate 54 that is rotatably connected to the end of the rotating rod 51 at the adjacent position. The two sides of the sewer 1 that are opposite to each other are fixedly connected. Both sides of the collecting bin 4 are fixedly connected with support blocks 3 15, both sides of the collecting bin 4 are fixedly connected with fixed blocks 2 44, one end of the outer wall of the sleeve 53 is fixedly connected with a synchronous wheel 1 55, both sides of the two sides of the sewer 1 are rotatably connected with shaft 2, the outer wall of shaft 2 is fixedly connected with a synchronous wheel 2 56 which is connected to the synchronous wheel 1 55 at the corresponding position through a synchronous belt transmission, the outer wall of shaft 2 is fixedly connected with a worm gear 57, a worm 58 which is rotatably connected with the worm gear 57 at the corresponding position is rotatably connected between the fixed block 2 44 and the adjacent support block 3 15, one end of the worm 58 penetrates the fixed block 2 44 at the corresponding position and is fixedly connected with a spur gear 59, and both sides of the dirt basket 42 which are opposite to each other are embedded with racks 43 which are meshed with the spur gear 59 at the corresponding position.

[0053] In this embodiment, the conveyor belt 31 is supported by eight sprockets II 52, and the chain 32 is engaged with the eight sprockets II 52 under the action of four rollers 161 to prevent detachment. When it is necessary to remove the garbage in the trash basket 42, the upward movement of the trash basket 42 will drive the two racks 43 at the corresponding positions to move upward. When the rack 43 meshes with the spur gear 59 at the corresponding position and the rack 43 continues to move upward, the spur gear 59 rotates under the upward movement of the rack 43 at the corresponding position. The rotating spur gear 59 can cause the worm 58 at the corresponding position to drive the worm gear 57 at the corresponding position to rotate. The rotating worm gear 57 can cause the synchronous pulley II 56 at the corresponding position to drive the synchronous pulley I 55 at the corresponding position to rotate. The rotating synchronous pulley I 55 can cause the sleeve 53 at the corresponding position to drive the connecting plate 54 at the corresponding position to rotate.

[0054] Embodiment Four

[0055] As Fig.11 shown, in this embodiment, two symmetric rectangular sleeves 17 are fixedly connected to an outer side surface of the manhole 1. A slider 171 with a tapered end is slidably sleeved inside the rectangular sleeve 17. A connecting block 172 is fixedly connected between the two sliders 171. A first spring is fixedly connected between the slider 171 and the rectangular sleeve 17. Two symmetric L-shaped plates 18 are fixedly connected to one side surface of the manhole 1. The switching mechanism 6 includes a U-shaped plate 61 that is rotatably penetrated through by a connecting rod 37 through a bearing. A stopper 62 with a tapered end is fixedly connected to the inner side surface of the U-shaped plate 61. A sleeve 63 is fixedly penetrated through the side surface of the L-shaped plate 18. A push rod 64 fixedly connected to the U-shaped plate 61 is slidably sleeved inside the sleeve 63. A connecting pipe 65 that is fixedly penetrated through the inner bottom of the corresponding collection bin 4 is fixedly penetrated through one end of the sleeve 63. A slide bar 151 is fixedly connected between two supporting blocks III 15 on the same side of the manhole 1. The other end of the U-shaped plate 61 is slidably penetrated through the slide bar 151. Second springs 66 are fixedly connected between both side surfaces of the U-shaped plate 61 and the corresponding supporting blocks III 15.

[0056] In this embodiment, firstly, a certain amount of water is put into the two collecting bins 4, and then the trash baskets 42 are respectively put into the collecting bins 4 at the corresponding positions. When the garbage in the trash baskets 42 increases, the floating plate 41 below the trash baskets 42 presses the water in the collecting bins 4 into the sleeves 63 at the corresponding positions through the connecting pipes 65, so that the top rod 64 at the corresponding positions can be extended. As the overall weight of the trash basket 42 increases, the pressure in the sleeves 63 at the corresponding positions will increase. When the overall weight of the trash basket 42 reaches the critical point, the pressure in the sleeves 63 at the corresponding positions reaches the maximum, so that the top rod 64 at the corresponding positions pushes the molded plate 61 to the other sleeve 63. When the pressure in the sleeves 63 reaches the maximum, the top rod 64 The pressure applied by the rod 64 to the shaped plate 61 will act on the two sliders 171 through the block 62. Therefore, when the pressure in the sleeve 63 reaches the maximum, the block 62 will press the two sliders 171 into the rectangular sleeve 17 at the corresponding position, so that the shaped plate 61 drives the block 62 to move to the other slider 171, and the movement of the shaped plate 61 will drive the connecting rod 37 to move, so that the other bevel gear five 38 is meshed with the bevel gear six for transmission, so that the conveyor belt 31 can rotate in the opposite direction.
