[0020] By adopting the above technical solution, the electromagnetic valve controls the flow rate of water inside the water delivery pipe to stabilize the flow rate, while the water supply device receives the water delivered from the water delivery pipe and thus transmits it.
[0021] Preferably, a protective ring is fixedly connected to the top inner side of the pressing ring, and a protective ring is fixedly connected to the bottom end of the pressing ring;
[0022] By adopting the above technical solution, the protective ring protects the internal structure of the manhole cover, and the protective ring also protects the gap between the pressing ring and the shell cover, making it stable.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. In this utility model, two connecting rings connect drain pipe one and drain pipe two, which are sealed by the sealing ring. The pressing strip is fixed to the two connecting rings by its own limiting groove.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.
[0032] Example: An intelligent rainwater harvesting, treatment, and recycling system, referring to... Figure 2 and Figure 3The system includes a water storage tank 1, which is used to store rainwater. The water storage tank 1 has multiple internal sections to collect rainwater of different levels. A fixing structure 2 is fixedly connected to the top of the water storage tank 1. The fixing mechanism is used to fix the manhole cover 21 on the top of the water storage tank 1 to make it stable. Drainage pipes 2 10 are fixedly connected to the left and right sides of the water storage tank 1. A sealing mechanism 7 is fixedly connected to the outside of the drainage pipes 2 10. A grading mechanism 5 is fixedly connected to the front of the water storage tank 1. The drainage pipes 2 10 transmit rainwater into the water storage tank 1. The sealing mechanism 7 seals the drainage pipes 2 10 and other transmission structures. The grading mechanism 5 filters the rainwater inside the water storage tank 1, separating it. The sealing mechanism 7 includes a sealing ring 72, which is fixedly connected to the outside of the second drain pipe 10. The sealing ring 72 seals the connection of the second drain pipe 10, making the connection stable. A connecting ring 71 is fixedly connected to the outside of the sealing ring 72, and a pressing strip 73 is fixedly connected to the outside of the connecting ring 71. A spring tension ring 74 is fixedly connected to the outside of the pressing strip 73. The connecting ring 71 connects the two drain pipes, connecting them. The pressing strip 73 receives external force, thereby stabilizing the connecting ring 71. The spring tension ring 74 fixes the pressing strip 73, making it stably fixed on the connecting ring 71.
[0033] Specifically, under the action of the sealing mechanism 7, the second drain pipe 10 is connected to another drain pipe. The drain pipe is connected to the water storage tank 1 to allow rainwater to enter the interior of the water storage tank 1 and stabilize it. The connecting ring 71 connects the two drain pipes. Under the action of the pressing strip 73, the connecting ring 71 is initially fixed. Under the action of the spring tension ring 74, the pressing strip 73 is used to stably fix the connecting ring 71. At the same time, under the action of the sealing ring 72, rainwater leakage is prevented.
[0034] Reference Figure 2 and Figure 3The grading mechanism 5 includes two protective plates 51, which protect the exterior of the water storage tank 1 and stabilize it. The adjacent sides of the two protective plates 51 are fixedly connected to the front and rear sides of the water storage tank 1. A water quality sensor 52 is fixedly connected to the rear side of the protective plate 51. The water quality sensor 52 is used to sense the rainwater that initially enters the water storage tank 1 from the drainage pipe 10 and performs height sensing. An isolation plate 53 is fixedly connected to the inner wall of the water storage tank 1. A transmission pipe 58 transmits the water in the initial rainwater collection area of the water storage tank 1 into the water storage area of the water storage tank 1. The transmission pipe 58 is fixedly connected inside the isolation plate 53 and is fixedly connected to the isolation plate 53 to stabilize it. Two fixing plates 54 are fixedly connected to the rear side of the isolation plate 53. The fixing plates 54 separate the clear water area and the water storage area to stabilize them. A push rod 55 is slidably connected inside the fixing plate 54. The push rod 55 receives power from the water quality sensor 52 and moves accordingly.
[0035] Specifically, the internal area of the water storage tank 1 is divided into three parts: the initial rainwater collection area, the water storage area, and the clear water area. The rainwater collection area is where rainwater from the drainage pipe 2 10 enters the water storage tank 1 and slowly enters the water storage area under the action of the water quality sensor. The rainwater is cleaned in the outlet area under the action of the water quality sensor. When the water quality reaches the standard, it causes the push rod 55 to move.
[0036] Reference Figures 1 to 3 The fixing mechanism 2 includes a manhole cover 21. The bottom of the manhole cover 21 is attached to the top of the water storage tank 1. The manhole cover 21 is fixed to the top of the water storage tank 1. A pressing ring 26 is engaged with the outer wall of the manhole cover 21. The pressing ring 26 receives external force and moves to open and close the manhole cover 21. Long plates 27 are fixedly connected to the left and right sides of the outer wall of the pressing ring 26. A sliding rod 28 is slidably connected to the inner side of the left long plate 27. The sliding rod 28 receives the force of the equipment to stabilize it. A threaded knob 23 is threadedly connected to the inner side of the right long plate 27. The threaded knob 23 controls the pressing ring 26 by rotation. T-shaped rods 24 are fixedly connected to the front and rear sides of the outer wall of the pressing ring 26. Anti-slip sleeves 22 are fixedly connected to the outer wall of the T-shaped rods 24.
[0037] Specifically, the bottom of the manhole cover 21 is only in contact with the top of the water storage tank 1. The operator can apply force to it by pressing the ring 26, so that the manhole cover 21 can be opened and closed to cover the water storage tank 1. When the operator needs to fix the manhole cover 21, the threaded knob 23 needs to be turned to fix the pressing ring 26 and fix the manhole cover 21.
[0038] Water supply pipes 3 are fixedly connected to both the left and right sides of the water storage tank 1. The water supply pipes 3 receive water from the water storage tank 1 and thus supply water. A solenoid valve 6 is fixedly connected to the outside of the drainage pipe 2 10. The solenoid valve 6 controls the flow rate of the water supply pipe 3 and opens and closes. When the water storage tank 1 is full, the solenoid valve closes. A drainage pipe 9 is fixedly connected to the outside of the drainage pipe 2 10. A gabion filter well 8 is fixedly connected to the outside of the drainage pipe 9. The drainage pipe 9 receives rainwater transmitted by the gabion filter well 8 and thus filters it. The gabion filter well 8 has multiple filter layers inside, which filters the rainwater in multiple layers to stabilize it. A conveying pipe 57 is fixedly connected inside the fixed plate 54. The push pipe receives the sensing of the water quality sensor and thus operates. A push block 56 is fixedly connected to the front of the push rod 55. The push block 56 receives the pushing force of the push rod 55 and thus moves to stabilize it.
[0039] The external sliding connection of the push block 56 is to the inside of the fixed plate 54, and the external sliding connection of the push block 56 is to the inside of the delivery pipe 57. The push block 56 receives the pushing force of the push rod 55, thereby limiting the delivery pipe 57. The external fixed connection of the two water supply pipes 3 is to the electromagnetic valve 11. The electromagnetic valve 11 receives the adjustment of the water supply volume, so as to adjust the size inside the water supply pipe 3 and make it stable. The two water supply pipes 3 are fixedly connected to the opposite side of each other. The water supply device 4 receives the water in the water storage tank 1 and makes adjustments. The inner top of the pressing ring 26 is fixedly connected to the protective ring 25, and the bottom end of the pressing ring 26 is fixedly connected to the protective ring 29. The protective ring 25 protects the well cover 21 and the pressing ring 26 to make them stable. The protective ring 29 increases the contact area between the pressing ring 26 and the water storage tank 1, thereby dispersing the pressure.
[0040] Specifically, the water supply pipe 3 receives water from the water storage tank 1 and then enters the water supply device 4. The solenoid valve 6 causes the water supply device 4 to flow quickly when it needs water. The drain pipe 9 receives rainwater from the gabion filter well 8 and then transfers it to the drain pipe 10. The push block 56 receives the pushing force of the push rod 55 and moves accordingly. The protective ring 25 receives the operating force of the equipment and operates accordingly, thus ensuring its stable protection.
[0041] The implementation principle of this application embodiment is as follows: First, the water storage tank 1 is connected to the drainage pipe. In addition, the gabion filter well 8 is connected to the drainage pipe 9. When it is necessary to connect the drainage pipe 9 and the drainage pipe, two connecting rings 71 are connected to the drainage pipe 10 and the drainage pipe 20 respectively. At the same time, the sealing ring 72 is used to seal the connection. Then, the pressing strip 73 is used to make multiple pressing strips 73 lock on the two connecting rings 71 to fix the connecting rings 71. Finally, the spring steel lock on the pressing strip 73 is locked to limit the pressing strip 73 and ensure that the connection does not loosen. This optimizes the connection structure of the gabion filter well 8 and the water storage tank, realizes the sealing of the two drainage pipes, and prevents rainwater leakage and loss, thereby ensuring sufficient water volume and operational stability of the collection component.
[0042] When water enters the reservoir 1, it triggers the water quality sensor 52 inside the protective plate 51. When the water level is too high, the water is transferred through the transmission pipe 58 into the storage area of the reservoir 1. The internal equipment of the reservoir 1 filters the water in the storage area. The sensor triggers the push rod 55 to drive the push block 56, causing the push block 56 to disengage from the transmission pipe 57. This allows the transmission pipe 57 to carry the water into the clean water area, thus achieving zoned management of the reservoir 1. In addition, rainwater can be stored in zones according to differences in rainwater quality, and rainwater from different areas can be treated in a targeted manner, thereby improving treatment efficiency and resource utilization.
[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
