Technical Field

[0002] The initial rainwater collection pool of traditional industrial enterprises is usually set independently, and an initial rainwater lift pump is equipped in the pool to lift and transport the initial rainwater to subsequent treatment facilities. Although this design can meet the basic requirements of initial rainwater collection, there are also some deficiencies: in the gravity flow mode, the traditional initial rainwater collection pool relies on gravity flow through the rainwater inlets on the ground to introduce rainwater into the collection pool through the rainwater pipeline, and then discharge it into the initial rainwater treatment station or natural water body. This method limits the effective volume of the collection pool, which is usually only the part of the space from the pipeline inlet to the bottom of the collection pool, while the space above the pipeline inlet is all invalid space and will not be used during the daily operation of the collection pool; the space utilization rate of the collection pool is low. Due to the limitation of the effective volume, the space utilization rate of the collection pool is low, resulting in a large floor area and a relatively high construction cost.

[0003] Therefore, there is a need for an initial rainwater collection and treatment system that can improve the space utilization rate of the initial rainwater collection pool while reducing the floor area and the project cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an initial rainwater collection and treatment system, which can improve the space utilization rate of the initial rainwater collection pool, reduce the floor area and lower the construction cost at the same time.

A flow channel gate is arranged between the inlet water flow channel and the water inlet pipe. On the top of the side of the rainwater pump suction pool far from the initial rainwater collection pool, there is a drainage station with one end communicated with it and the other end respectively communicated with the initial rainwater treatment station, the natural water body and the initial rainwater collection pool; the collection pool gate, the suction pool gate, the flow channel gate, the rainwater pump suction pool and the drainage station are all regulated by the controller according to the level signals transmitted by the corresponding ultrasonic level gauges.

[0007] A further improvement of the technical solution of the present utility model lies in that: several water suction pumps are arranged in parallel at the bottom of the rainwater pump suction pool, and each water suction pump is connected to the drainage station through a water suction pump pipeline; the controller regulates each water suction pump according to the liquid level signal transmitted by the ultrasonic liquid level gauge of the rainwater pump suction pool, and the number of water suction pumps started is proportional to the liquid level height.

[0008] A further improvement of the technical solution of the present utility model lies in that: the drainage station includes three drainage pipelines arranged in parallel, and one end of each of the three drainage pipelines is connected to the water suction pump pipeline, and the other ends are respectively connected to the initial rainwater treatment station, the natural water body and the initial rainwater collection pool through electric butterfly valves, and each electric butterfly valve is regulated by the controller according to the liquid level signals transmitted by the ultrasonic liquid level gauges of the initial rainwater collection pool, the rainwater pump suction pool and the water inlet channel.

[0009] A further improvement of the technical solution of the present utility model lies in that: the water inlet channel and the top of the rainwater pump suction pool are open and steel gratings are respectively laid, and a trash rack is arranged inside the water inlet channel along its height direction.

[0021] The following further elaborates on the present utility model in conjunction with embodiments:

[0022] As Figures 1 - 3As shown in the figure, an initial rainwater collection and treatment system includes an initial rainwater collection tank 1, a rainwater pump suction tank 2, and an influent channel 5, each of which is equipped with an ultrasonic level gauge 9. The rainwater pump suction tank 2 is located on one side of the initial rainwater collection tank 1, that is, on the left or right side of the initial rainwater collection tank 1. The rainwater pump suction tank 2 is connected to the initial rainwater collection tank 1 through a collection tank gate 3. The collection tank gate 3 is arranged near the bottom of the side wall of the initial rainwater collection tank 1. The influent channel 5 is located in front of the rainwater pump suction tank 2. One end of the influent channel 5 is connected to the rainwater pump suction tank 2 through a suction tank gate 4, and the other end is connected to the rainwater pipeline through an influent pipe 7. The suction tank gate 4 is arranged near the bottom of the side wall of the rainwater pump suction tank 2. A channel gate 6 is arranged between the influent channel 5 and the influent pipe 7. A drainage station 8 is also arranged on the rainwater pump suction tank 2. The drainage station 8 is arranged at the top of the side of the rainwater pump suction tank 2 away from the initial rainwater collection tank 1. One end of the drainage station 8 is connected to the rainwater pump suction tank 2, and the other end is respectively connected to the initial rainwater treatment station, the natural water body, and the initial rainwater collection tank 1. The collection tank gate 3, the suction tank gate 4, the channel gate 6, the rainwater pump suction tank 2, and the drainage station 8 are all regulated by a controller arranged on the ground. The controller controls them according to the liquid level signals transmitted by the corresponding ultrasonic level gauges 9, realizing the intelligent operation of the system and improving the operation efficiency and accuracy.

[0023] Specifically, several suction pumps 2-1 are arranged in parallel at the bottom of the rainwater pump suction tank 2. Each suction pump 2-1 is connected to the drainage station 8 through a suction pump pipeline 2-2. The water pumped out by each suction pump 2-1 is gathered in the suction pump pipeline 2-2 and flows into the drainage station 8. The controller regulates each suction pump 2-1 according to the liquid level signals transmitted by the ultrasonic level gauge 9 of the rainwater pump suction tank 2. The number of suction pumps 2-1 started is proportional to the liquid level height. As the liquid level rises, the number of suction pumps 2-1 started also increases. For example, when the ultrasonic level gauge 9 detects that the liquid level in the rainwater pump suction tank 2 is at the first start-up liquid level, the controller controls one suction pump 2-1 to start. When the ultrasonic level gauge 9 detects that the liquid level in the rainwater pump suction tank 2 is at the second start-up liquid level, the controller controls two suction pumps 2-1 to start. When the ultrasonic level gauge 9 detects that the liquid level in the rainwater pump suction tank 2 is at the third start-up liquid level, the controller controls three suction pumps 2-1 to start, and so on. Among them, the first start-up liquid level < the second start-up liquid level < the third start-up liquid level. When the ultrasonic level gauge 9 detects that the liquid level in the rainwater pump suction tank 2 is at the pump stop liquid level, the controller controls all suction pumps 2-1 to stop.

[0024] The drainage station 8 includes three drainage pipes 8-1 arranged in parallel. The drainage pipes 8-1 are successively provided with expansion joints and check valves along the drainage direction. One ends of the three drainage pipes 8-1 are all connected to the suction pump pipe 2-2, and the other ends are respectively connected to the initial rainwater treatment station, natural water body, and initial rainwater collection pool 1 through electric butterfly valves 8-2. Each electric butterfly valve 8-2 is regulated by the controller according to the liquid level signals transmitted by the ultrasonic liquid level gauges 9 of the initial rainwater collection pool 1, rainwater pump suction pool 2, and intake channel 5 it receives.

[0025] The top openings of the intake channel 5 and the rainwater pump suction pool 2 are paved with steel gratings 11 respectively, to prevent sundries from being carried when rainwater falls into the interior. A trash rack 10 is arranged inside the intake channel 5 along its height direction, which can effectively prevent the rainwater flowing in through the rainwater pipe from carrying sundries. An overflow hole 12 is arranged between the tops of the initial rainwater collection pool 1 and the rainwater pump suction pool 2, which can effectively prevent overflow caused by excessive rainwater. The top of the initial rainwater collection pool 1 is closed and provided with vent pipes 13 symmetrically, which helps to balance the air pressure inside and outside the pool, prevent the formation of negative pressure or vacuum, and ensure the normal operation of the system.

[0026] The initial rainwater collection pool 1, rainwater pump suction pool 2, and intake channel 5 are integrated into a cuboid structure. Among them, the rainwater pump suction pool 2 and the intake channel 5 are in an L-shaped structure and semi-surround the initial rainwater collection pool 1, making the structure compact and saving floor space. And fences 14 are arranged along the outer periphery of the tops of the rainwater pump suction pool 2 and the intake channel 5. Sumps are arranged on the initial rainwater collection pool 1, rainwater pump suction pool 2, intake channel 5, and drainage station 8.

[0027] The operation mode of the initial rainwater collection and treatment system is as follows:

[0028] 1) At the beginning of rainfall

[0029] Rainwater enters the intake channel 5 through the steel grating 11 at the top of the intake channel 5. When the ultrasonic liquid level gauge 9 of the intake channel 5 detects that the rainwater in the intake channel 5 reaches the start liquid level of the channel gate 6 and the suction pool gate 4 and transmits this signal to the controller, the controller controls the channel gate 6 and the suction pool gate 4 to open, so that the initial rainwater passes through the rainwater pipe, inlet pipe 7 into the intake channel 5, and then enters the rainwater pump suction pool 2 after removing sundries through the trash rack 10. At this time, the collection pool gate 3 is closed;

[0030] When the ultrasonic level gauge 9 in the rainwater pump sump 2 detects that the rainwater in the rainwater pump sump 2 reaches the starting level of the suction water pump 2-1 and transmits this signal to the controller, the controller controls the start of the corresponding number of suction water pumps 2-1 according to the corresponding starting level. At the same time, the controller controls the opening of the electric butterfly valve 8-2 on the drainage pipeline 8-1 communicating with the initial rainwater collection tank 1. At this time, the electric butterfly valve 8-2 on the drainage pipeline 8-1 communicating with the initial rainwater treatment station and the natural water body is closed. The initial rainwater is lifted by the suction water pump 2-1 and enters the initial rainwater collection tank 1 through the suction water pump pipeline 2-2 and the above-mentioned opened drainage pipeline 8-1, collecting the initial rainwater;

[0031] 2) During rainfall

[0032] When the ultrasonic level gauge 9 detects that the rainwater collected in the initial rainwater collection tank 1 reaches the highest level and transmits this signal to the controller, the controller controls the opening of the electric butterfly valve 8-2 on the drainage pipeline 8-1 communicating with the natural water body. At this time, the electric butterfly valve 8-2 on the drainage pipeline 8-1 communicating with the initial rainwater collection tank 1 and the initial rainwater treatment station is closed. The initial rainwater no longer enters the initial rainwater collection tank 1, but is lifted by the suction water pump 2-1 and enters the natural water body through the suction water pump pipeline 2-2 and the above-mentioned opened drainage pipeline 8-1;

[0033] 3) Carry out initial rainwater treatment after rainfall stops

[0034] When the ultrasonic level gauge 9 in the inlet channel 5 detects that the rainwater in the inlet channel 5 drops to the closing level of the channel gate 6 and the sump gate 4 and transmits this signal to the controller, the controller controls the closing of the channel gate 6 and the sump gate 4. At the same time, the controller controls the opening of the collection tank gate 3 and the electric butterfly valve 8-2 on the drainage pipeline 8-1 communicating with the initial rainwater treatment station. At this time, the electric butterfly valve 8-2 on the drainage pipeline 8-1 communicating with the initial rainwater collection tank 1 and the natural water body is closed. The initial rainwater collected in the initial rainwater collection tank 1 is lifted by the suction water pump 2-1 and enters the initial rainwater treatment station through the suction water pump pipeline 2-2 and the above-mentioned opened drainage pipeline 8-1. During this process, the controller adjusts and controls the start of the corresponding number of suction water pumps 2-1 according to the level corresponding to the amount of rainwater discharged from the initial rainwater collection tank 1 into the rainwater pump sump 2.
