Description

Technical Field

[0001] The invention relates to the technical field of rainwater collection devices, and in particular to an urban rainwater collection and treatment device. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, with good flexibility. It can also be called a water-elastic city. It absorbs, stores, infiltrates and purifies water when it rains. When needed, the stored water is released and utilized to achieve the free migration of rainwater in the city. Therefore, rainwater needs to be collected.

[0003] After searching, the existing patent (Announcement No.: CN216566567U) discloses a rainwater collection and purification device for sponge cities. It is configured by matching a motor, a screw, a threaded hole, a pulse jet and a nozzle. When the filter hole is blocked, the pulse jet is turned on to generate a pulse airflow, and then the pulse airflow can impact the blocked filter hole through the nozzle. The motor is turned on to drive the screw to rotate, and the screw can drive the pulse jet to move in a straight line through the threaded transmission, so that the filter hole inside the collection bin can be cleaned, which can prevent the filter hole from being blocked and affecting the rainwater recovery rate.

[0004] However, there are still some shortcomings in the above scheme:

[0005] 1. During the cleaning process of the filter, it needs to be driven by a motor and a pulse jet to perform jet treatment, and the filter cannot be self-cleaned, which makes the device more expensive to use. At the same time, the motor and pulse jet need to be powered, resulting in poor applicability of the device and inconvenience in adjusting the working position of the device according to actual needs;

[0006] 2. It only has a simple rainwater collection function. After the rainwater is collected, it needs to be transported into the storage tank for subsequent sedimentation and disinfection processes. It is impossible to carry out certain disinfection and flocculation treatment on the rainwater during the collection process, resulting in complicated subsequent work processes.

[0007] In view of this, the present invention proposes an urban rainwater collection and treatment device. Summary of the invention

The first pulley 91 is fixedly connected to one end of the shaft 71, and the second pulley 93 is coaxially fixed to the first rotating roller 61.

[0060] Furthermore, the cleaning assembly 3 includes two through holes 33 symmetrically opened on the outer wall of the collection frame 13, and a spherical ring cavity 32 is opened on the outer wall of the collection frame 13 located outside the through holes 33. A rotating rod 36 is sleeved between the two through holes 33. The inner diameter of the through hole 33 is larger than the diameter of the rotating rod 36. A threaded section 34 is arranged at one end of the rotating rod 36, and bristles 35 are distributed on the outer wall of the rotating rod 36. A connecting ring 37 is fixedly sleeved on the outer wall of one end of the rotating rod 36, and another connecting ring 37 is detachably installed on the other end of the rotating rod 36.

[0061] Furthermore, the linkage assembly 5 includes a first pinion 52, a second pinion 53 and a large gear 51 coaxially fixed with the second rotating roller 62. The first pinion 52 and the second pinion 53 are respectively fixed to the ends of the rotating rods 36 on the two cleaning assemblies 3, and the large gear 51 and the second pinion 53 are both meshed with the first pinion 52.

[0062] In this embodiment, rainwater flows into the inner side of the support frame 12 through the rain collecting hopper 11. At this time, the rainwater will first be collected by the water collecting box 73 outside the shaft 71. As the rainwater inside the water collecting box 73 accumulates rapidly, the weight of the rainwater increases rapidly.

[0064] Example 3

[0065] See also Figure 2 , Figure 3 , Figure 6 as well as Figure 7 A device for collecting and treating urban rainwater includes all the contents of Example 2. In addition, a drug injection mechanism 8 is provided, wherein the drug injection mechanism 8 is provided on a support frame 12. During the transmission process of a gravity-driven mechanism 7, the drug injection mechanism 8 can intermittently add drugs to the water storage cavity of a collection frame 13.

[0066] Specifically, the drug injection mechanism 8 includes a support plate 82 fixed to the outer wall of the support frame 12 by bolts, a medicine cartridge 81 is arranged at the upper end of the support plate 82, a medicine liquid temporary storage component 83 is arranged on the inner side of the support frame 12, and a pumping component 84 is arranged on the lower side of the medicine liquid temporary storage component 83. During the rotation of the gravity-driven mechanism 7, the medicine liquid temporary storage component 83 can be driven by the pumping component 84, so that the medicine liquid stored in the medicine cartridge 81 can be extracted and discharged by the medicine liquid temporary storage component 83.

[0067] Furthermore, the liquid medicine temporary storage component 83 includes a fixed plate 836 fixedly connected to the inner wall of the support frame 12, a temporary storage tube 832 is fixedly connected to the bottom of the fixed plate 836, a piston column 831 is slidably sleeved inside the temporary storage tube 832, a discharge pipe 835 and a suction pipe 834 connected to the interior of the temporary storage tube 832 are arranged on the upper side of the temporary storage tube 832, and a one-way valve 833 is arranged at one end of the discharge pipe 835 and the suction pipe 834 connected to the temporary storage tube 832, and the suction pipe 834 passes through the outer wall of the support frame 12 and is fixedly connected to the bottom of the medicine cartridge 81.

[0068] Furthermore, the pumping assembly 84 includes a right angle frame 842 fixedly connected to the inner wall of the support frame 12, and a pressure rod 841 is hingedly connected to the upper end of the right angle frame 842, one end of the pressure rod 841 is located below the water receiving box 73, and the other end of the pressure rod 841 is hingedly connected to a push-pull rod 845, and the upper end of the push-pull rod 845 is hinged to the bottom end of the piston column 831. The outer wall of the right angle frame 842 is fixedly connected with a pressure rod 841 for supporting and limiting the pressure rod 841, and a spring 844 is connected between the pressure rod 841 and the right angle frame 842.

[0069] In this embodiment, when rainwater is collected, sewage treatment liquids such as flocculants, alum, and disinfectants are added to the cartridge 81 in advance, and rainwater flows into the inner side of the support frame 12 through the rain collecting bucket 11. At this time, the rainwater will first be collected by the water receiving box 73 outside the shaft 71. As the rainwater inside the water receiving box 73 accumulates rapidly, the weight of the rainwater increases rapidly. When the rainwater reaches a certain amount, the shaft 71 will be driven to rotate, causing the water receiving box 73 to revolve. One of the water receiving boxes 73 One end of the pressure rod 841 will be pressed down, causing the other end of the pressure rod 841 to move upward, and the spring 844 will be stretched. The push-pull rod 845 will be supported by the pressure rod 841, and the push-pull rod 845 will push the piston column 831 upward inside the temporary storage tube 832, so that the one-way valve 833 at one end of the drain pipe 835 is opened and the one-way valve 833 at one end of the suction pipe 834 is closed, so that the medicine inside the temporary storage tube 832 can be discharged into the rainwater collected inside the collection frame 13 through the drain pipe 835. As the water collecting box 73 continues to revolve, it will separate from the pressure rod 841. At this moment, the originally stretched spring 844 will pull down the pressure rod 841, so that the pressure rod 841 placed on the upper end of the T-bar 843 will return to a horizontal state. During this process, the pressure rod 841 pulls down the piston column 831 through the push-pull rod 845. At this time, the one-way valve 833 at one end of the discharge pipe 835 is closed, and the one-way valve 833 at one end of the suction pipe 834 is opened, and the medicine liquid inside the medicine cartridge 81 is pumped into the temporary storage tube 832 for temporary storage through the suction pipe 834, and the next round of medicine liquid addition work is continued.

[0070] Working principle and use process: When collecting rainwater, flocculants, alum and other sewage treatment liquids are added to the cartridge 81 in advance, and rainwater flows into the inner side of the support frame 12 through the rain collecting bucket 11. At this time, the rainwater will first be collected by the water receiving box 73 outside the shaft 71. As the rainwater inside the water receiving box 73 accumulates rapidly, the weight of the rainwater increases rapidly. When the rainwater reaches a certain amount, it will drive the shaft 71 to rotate, causing the water receiving box 73 to revolve. One of the water receiving boxes 73 One end of the pressure rod 841 will be pressed down, causing the other end of the pressure rod 841 to move upward, and the spring 844 will be stretched. The push-pull rod 845 will be supported by the pressure rod 841, and the push-pull rod 845 will push the piston column 831 upward inside the temporary storage tube 832, so that the one-way valve 833 at one end of the drain pipe 835 is opened and the one-way valve 833 at one end of the suction pipe 834 is closed, so that the medicine inside the temporary storage tube 832 can be discharged into the rainwater collected inside the collection frame 13 through the drain pipe 835. As the water collecting box 73 continues to revolve, it will separate from the pressure rod 841. At this moment, the originally stretched spring 844 will pull down the pressure rod 841, so that the pressure rod 841 placed on the upper end of the T-bar 843 will return to a horizontal state. During this process, the pressure rod 841 pulls down the piston column 831 through the push-pull rod 845. At this time, the one-way valve 833 at one end of the discharge pipe 835 is closed, and the one-way valve 833 at one end of the suction pipe 834 is opened, and the medicine liquid inside the medicine cartridge 81 is pumped into the temporary storage tube 832 for temporary storage through the suction pipe 834, and the next round of medicine liquid addition work is continued.

[0071] When the shaft 71 rotates, the first pulley 91 drives the second pulley 93 to rotate through the transmission belt 92, and the second pulley 93 drives the first roller 61 to rotate. Under the action of the chain 65 and the first transmission gear 63, the first roller 61 and the second roller 62 rotate synchronously. Under the action of the first roller 61 and the third roller 64, the filter 2 is driven, thereby achieving the purpose of intermittent movement of the filter 2. During the rotation of the second roller 62, the large gear 51 can be driven to rotate. The large gear 51 drives the second small gear 53 to rotate through the first small gear 52, and the rotation speed of the first small gear 52 and the second small gear 53 is greater than the rotation speed of the large gear 51. The first small gear 52 and the second small gear 53 respectively drive the two rotating rods 36 to rotate, and the bristles 35 on the rotating rods 36 are used to rub and clean the outer wall of the filter 2. At the same time, since the height of the third roller 64 is lower than that of the second roller 62, the filter screen 2 located between the second roller 62 and the third roller 64 is in an inclined state, and the filter screen 2 located between the second roller 62 and the third roller 64 is not blocked by the support frame 12 and is in an exposed state, so that external rainwater can directly wash the upper surface of the filter screen 2, and the filtered rainwater can wash the lower surface of the filter screen 2, which, combined with the friction cleaning of the cleaning component 3, can greatly improve the cleaning force of the filter screen 2.

[0072] As the rainwater inside the water storage chamber of the collection frame 13 is continuously intermittently collected and accumulated, the liquid medicine inside the cartridge 81 is continuously intermittently added in a quantitative manner. When the added liquid medicine is a flocculant, the suspended matter in the rainwater inside the water storage chamber of the collection frame 13 is continuously precipitated. The dirt precipitated in the collected rainwater can be collected and processed through the dirt collecting box 4 slidably mounted on the bottom of the collection frame 13.

[0073] After a long period of work, when the cleaning assembly 3 needs to be disassembled, replaced or cleaned, the threaded sleeve 31 is rotated to remove one of the connecting rings 37 from the end of the rotating rod 36, and the rotating rod 36 is pulled out from the inside of the collecting frame 13 through the other connecting ring 37.
