Description

Technical Field

[0001] This utility model is a garden flood control and rainwater harvesting device, belonging to the field of gardening. Background Technology

[0002] A concrete stormwater retention tank is installed underground in the core area of ​​the garden. Its volume is designed based on the garden's catchment area and the intensity of rainstorms (usually calculated based on a 20-30 year return period). During heavy rains, it quickly collects rainwater to prevent surface water accumulation. After rain, pumps drain the rainwater from the retention tank to landscape water features or rainwater collection tanks for recycling. During the process of rainwater flowing into the retention tank, it inevitably carries soil from the garden surface. Even if source facilities (such as permeable paving layers and rain garden filters) intercept some sediment, fine mud particles still enter the retention tank with the rainwater. These mud particles settle and gradually accumulate at the bottom of the tank, forming a silt layer. When the pumps are started, a significant amount of silt flows into the piping system, increasing the probability of pipe blockage. Furthermore, because the silt flows at high speeds within the pipes, the pumps face greater resistance and operate under heavy loads, increasing the likelihood of pump failure. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a garden flood control and rainwater harvesting device to solve the problems mentioned in the background technology.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a garden flood control and rainwater harvesting device, comprising: The storage tank has an open top. A water pump with a straight pipe installed at the outlet end, and a water outlet valve installed at the upper end of the straight pipe; The first valve has a first suction pipe installed at one end. The end of the first suction pipe away from the first valve is installed on the lower part of one side of the storage tank and is connected to the storage tank. The end of the first valve away from the first suction pipe has a first bend pipe installed. The second valve has a second suction pipe installed at one end. The end of the second suction pipe away from the second valve passes through the storage tank and extends to the upper part of the storage tank. The end of the second valve away from the second suction pipe has a second bend pipe installed. The second bend pipe and the first bend pipe are connected to the inlet end of the water pump through a connector. The third valve is installed on the outer surface of the straight pipe and communicates with the straight pipe. A thin tube is installed at the end of the third valve away from the straight pipe. The end of the thin tube away from the third valve extends to a position in the storage tank near the first suction pipe.

[0005] Furthermore, the connector includes a tee pipe, and the three ends of the tee pipe are respectively equipped with a first bend, a second bend, and a fourth valve, and the fourth valve is installed at the inlet end of the water pump.

[0006] Furthermore, a water tank is provided below the water pump, the upper end of the water tank is open, the water pump is installed in the upper part of the water tank, and the first valve, second valve, third valve, fourth valve and water outlet valve are all located directly above the water tank.

[0007] Furthermore, a pipe connector for connecting a drain pipe is installed on the lower part of one side of the water tank, and the pipe connector is in communication with the internal space of the water tank.

[0008] Furthermore, a positioning plate is installed on the side of the water tank that is connected to the pipe joint, and two fixing holes are opened on the upper surface of the positioning plate.

[0009] Furthermore, a bracket is bolted to the bottom of the water pump, and a support frame is installed at the bottom of the bracket. The lower end of the support frame is installed at the bottom of the water tank.

[0010] Furthermore, the end of the water outlet valve away from the straight pipe is equipped with a detachable connecting pipe for connecting to the delivery pipeline, and the connecting pipe has an L-shaped structure.

[0011] Furthermore, a first circular opening is machined at the lower part of one side of the storage tank, and the end of the first water suction pipe away from the first valve is installed in the first circular opening. A second circular opening is opened at the lower part of one side of the storage tank, and the second water suction pipe passes through the second circular opening.

[0012] The beneficial effects of this utility model are: With the outlet valve and the first valve closed, and the second, third, and fourth valves opened, the water pump draws clean water from the upper part of the storage tank through the second suction pipe. This area is far from the silt layer at the bottom of the tank, preventing silt from being sucked into the pipes. Rainwater entering through the second suction pipe then flows back into the storage tank through a thin pipe, dispersing the silt layer at the bottom. After the silt mixes with the rainwater, the outlet valve, the first valve, and the fourth valve are opened, and the second and third valves are closed. At this point, the silt mixed with the rainwater has good fluidity, the pipes do not need to bear the frictional resistance of the silt, and the water pump load is within the normal range. This reduces the probability of pipe blockage and motor overload losses, ensuring stable equipment operation. Attached Figure Description

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a garden flood control and rainwater harvesting device, including a regulating tank 1, the upper end of which is open, a straight pipe 22 installed at the outlet end of a water pump 2, a water outlet valve 23 installed at the upper end of the straight pipe 22, and a detachable connecting pipe 24 for connecting to a conveying pipeline installed at the end of the water outlet valve 23 away from the straight pipe 22. The connecting pipe 24 has an L-shaped structure. A first suction pipe 51 is installed at one end of a first valve 5. The end of the first suction pipe 51 away from the first valve 5 is installed at the lower part of one side of the regulating tank 1 and communicates with the regulating tank 1. A first suction pipe 51 is installed at the end of the first valve 5 away from the first suction pipe 51. A bend 52 is installed at one end of the second valve 6, and a second suction pipe 61 is installed at one end of the second valve 6. The end of the second suction pipe 61 away from the second valve 6 passes through the storage tank 1 and extends to the upper part of the storage tank 1. A second bend 62 is installed at the end of the second valve 6 away from the second suction pipe 61. A first round opening is machined at the lower part of one side of the storage tank 1. The end of the first suction pipe 51 away from the first valve 5 is installed in the first round opening. A second round opening is opened at the lower part of one side of the storage tank 1. The second suction pipe 61 passes through the second round opening. The first round opening and the second round opening provide space for the assembly of the first suction pipe 51, the second suction pipe 61 and the storage tank 1.

[0016] See Figures 1-4 The three ends of the three-way pipe 41 are respectively equipped with a first bend 52, a second bend 62 and a fourth valve 4. The fourth valve 4 is installed at the inlet end of the water pump 2. The third valve 3 is installed on the outer surface of the straight pipe 22 and communicates with the straight pipe 22. A thin pipe 31 is installed at the end of the third valve 3 away from the straight pipe 22. The end of the thin pipe 31 away from the third valve 3 extends to the storage tank 1 near the first suction pipe 51. When a large amount of rainwater is stored in the storage tank 1 after rain, and the water in the storage tank 1 has formed a layered state of upper clear water layer and lower silt layer due to stagnation, the outlet valve 23 and the first valve 5 are closed, and the second valve 6, the third valve 3 and the fourth valve 4 are opened simultaneously. At this time, after the water pump 2 starts, it will draw clean water away from the silt layer at the bottom of the tank through the second suction pipe 61 that extends to the upper part of the storage tank 1. The rainwater in this area contains almost no mud or sand impurities, and will not cause the pipe wall to adhere or block after entering the pipe. At the same time, the clean water has good flowability, and the water pump 2 does not need to overcome the additional frictional resistance of the silt. The motor load is stable within the rated range, which avoids the hidden danger of pipe blockage caused by silt suction and reduces the failure of coil aging, overheating and tripping caused by motor overload, thus ensuring the stability of the equipment in the initial operation.

[0017] While pumping out the upper clean water, the straight pipe 22 and the thin pipe 31 at the outlet of the water pump 2 form a return loop. Since the outlet valve 23 is closed, the pressurized clean water from the water pump 2 cannot be transported outwards. Instead, it enters the thin pipe 31 through the third valve 3 connected to the outer surface of the straight pipe 22, and is finally sprayed into the bottom of the storage tank 1 from the end of the thin pipe 31. The high-pressure water flow impacts the silt layer accumulated at the bottom of the tank, breaking up the hardened silt into fine particles, allowing the silt to be evenly mixed into the surrounding rainwater. Compared to traditional manual dredging, this water flushing method does not require disassembling equipment or entering the storage tank 1 for operation. It can loosen the silt online, and the flushed silt and rainwater form a fluid mixture, preventing the silt from clogging the first suction pipe 51 due to hardening, thus preparing for the subsequent thorough drainage of the storage tank 1. Meanwhile, the directional flushing design of the thin tube 31 can be applied to the area around the first suction pipe 51 to ensure that there is no silt accumulation at the opening of the first suction pipe 51, thus clearing obstacles for subsequent water intake from the lower part.

[0018] After the silt at the bottom of the pool is completely dispersed and evenly mixed with rainwater, open the outlet valve 23, the first valve 5, and the fourth valve 4, and close the second valve 6 and the third valve 3. At this time, the water pump 2 draws the rainwater and silt mixture from the storage tank 1 through the first suction pipe 51 at the bottom. Since the silt has been dispersed into fine particles and evenly dispersed in the rainwater, the mixture has good overall fluidity and will not cause strong friction on the inner wall of the pipe like hardened silt. There will also be no situation where large particles of silt get stuck in the pipe bends or the pump impeller. The load of the water pump 2 is always maintained within the normal operating range, and the motor current is stable. This avoids equipment failure due to excessive load and ensures that the rainwater and silt in the storage tank 1 can be completely pumped out. The pumped mixture can be transported to the landscape water body or special treatment facilities as needed, realizing the rapid emptying of the storage tank 1 and preparing for the next rainstorm.

[0019] The entire operation process seamlessly connects the three stages of clean water extraction, sludge flushing, and mixed water discharge through the orderly switching of valves. This not only solves the contradiction of traditional single-pipe systems either failing to extract clean water or sucking in sludge, but also improves the smoothness of sludge discharge through dynamic flushing. The mixed liquid formed after sludge flushing has good fluidity, avoiding pipe blockage and high pump load, extending the service life of core components such as pump 2 and pipes, reducing the operation and maintenance costs and failure frequency of the garden flood control and rainwater harvesting system, and ensuring that the equipment can quickly and stably complete rainwater drainage and recycling after heavy rain, providing reliable support for garden flood control and efficient water resource utilization.

[0020] See Figure 1 , Figure 2 and Figure 4 A water tank 7 is located below the water pump 2, with an open top. The water pump 2 is installed in the upper part of the water tank 7. A bracket 21 is bolted to the bottom of the water pump 2, and a support frame 25 is installed at the bottom of the bracket 21. The lower end of the support frame 25 is installed at the bottom of the water tank 7. The first valve 5, the second valve 6, the third valve 3, the fourth valve 4, and the outlet valve 23 are all located directly above the water tank 7. A pipe connector 73 for connecting the inlet and outlet pipe is installed on the lower part of one side of the water tank 7. 73 is connected to the internal space of water tank 7. A positioning plate 71 is installed on the side of water tank 7 connected to pipe joint 73. Two fixing holes 72 are opened on the upper surface of positioning plate 71. The positioning plate 71 is installed at the required position in the pump room using fixing holes 72. When leakage occurs at the connection of water pump 2, first valve 5, second valve 6, third valve 3, fourth valve 4 or outlet valve 23, the leaked water flows into water tank 7. Then the water collected in water tank 7 is discharged through the drain pipe.
