Description

Technical Field

[0001] The utility model provides a water quality monitoring and purification device for a sponge city water reservoir, belonging to the technical field of water reservoirs. Background Art

[0002] Traditional urban development often neglects rainwater collection, storage, and utilization, leading to flooding during heavy rains and water shortages during droughts. To address these issues, many cities are adopting the "sponge city" concept. By mimicking the forms and mechanisms of natural ecosystems, these cities are building ecosystems that can adapt to environmental changes and withstand natural disasters.

[0003] As a crucial component of sponge cities, reservoirs should be designed to store rainwater while ensuring stable water quality. However, in practice, the water collected in reservoirs is often rainwater. During the collection process, rainwater is often exposed to various pollutants, including domestic sewage and agricultural runoff, leading to a decline in water quality and impacting its use and safety. Therefore, water purification structures are typically installed within reservoirs to purify the collected rainwater. When testing the water purification capacity of a reservoir, water quality monitoring systems are often required to monitor and compare rainwater before and after purification. However, sampling rainwater before and after purification is cumbersome, requiring staff to set up sampling ports at both the inlet and outlet of the reservoir. After sampling, the samples must be transferred to water quality testing equipment for testing. After testing, the rainwater samples are often discarded, resulting in a waste of water resources. Utility Model Content

[0004] The technical problem to be solved by the present invention is that when monitoring and comparing rainwater before and after purification, the sampling and testing operation is relatively troublesome, and the rainwater after testing is often directly discharged, which easily causes waste of water resources.

[0021] By setting up the monitoring box 3 as a container for the monitored rainwater samples and using the sealing block 17 to freely control the connection between the monitoring box 3 and the water reservoir 1, it is convenient to sample and test the rainwater before and after purification, and after the test is completed, the sample rainwater can be reintroduced into the water reservoir 1 to reduce the waste of rainwater.

[0022] like Figure 4 As shown, the sealing structure includes a sealing block 17 and a plug 16. The sealing block 17 is fixedly arranged on the lifting plate 11, and the plug 16 is fixedly connected to the sealing block 17. When the lifting plate 11 rises, the plug 16 can be inserted into the connecting hole 13, and at the same time can drive the sealing block 17 to block the connecting hole 13.

[0023] The number of sealing blocks 17, plug posts 16 and connecting holes 13 is the same, and the positions of sealing blocks 17, plug posts 16 and connecting holes 13 correspond to each other; a drainage groove 18 is provided on the lifting plate 11, and the setting of the drainage groove 18 will not affect the normal downward flow of rainwater.

[0024] like Figure 3 、 4 As shown, a motor 19 is installed on the water reservoir 1.

The lifting plate 11 is slidably mounted on the guide rod 15, and the lower end of the guide rod 15 is fixedly connected to a limit block 14.

Valves are provided on the water inlet pipe 2 and the water outlet pipe 6 to facilitate the control of the water flow.

[0027] Principle of the utility model

[0028] like Figure 1-2 As shown, when the water reservoir 1 provided by the present application is in normal use, rainwater is collected and enters the monitoring box 3 from the water inlet pipe 2, then enters the water reservoir 1 through the connecting hole 13, and after being filtered by the filter layer and purified by the activated carbon purification layer, enters the bottom of the water reservoir 1. Figure 3 、 4 As shown, when it is necessary to monitor the water quality of rainwater before purification, the motor 19 is started to drive the lifting plate 11 to move upward, the plug 16 is inserted into the connecting hole 13, and the sealing plate 9 blocks the connecting hole 13. At this time, the rainwater in the monitoring box 3 can no longer enter the water reservoir 1; after a period of time, more and more rainwater enters the monitoring box 3 from the water inlet pipe 2. When the sample volume required for monitoring is reached, the valve on the water inlet pipe 2 is closed. The water quality monitor 5 and the monitoring head 12 can be used to directly test the water quality of the rainwater. After the test is completed, the motor 19 is reversed, and the lifting plate 11 drives the sealing plate 9 to move downward, so that the sealing plate 9 no longer seals the connecting hole 13. At this time, the rainwater after testing can directly enter the water reservoir 1 through the connecting hole 13, avoiding the waste of water resources.

[0029] When it is necessary to monitor the water quality of the purified rainwater, while ensuring that the valve of the water inlet pipe 2 is closed, start the water pump 7, adjust the valve on the outlet pipe 6, and introduce the purified rainwater at the bottom of the water reservoir 1 into the monitoring box 3 through the outlet pipe 6. After a period of time, use the sealing plate 9 to block the connecting hole 13 again until an appropriate amount of purified rainwater is stored in the monitoring box 3. The water quality monitor 5 and the monitoring head 12 can be used to directly detect the water quality of the purified rainwater; similarly, after the detection is completed, the lifting plate 11 is moved down, and the detected rainwater can enter the water reservoir 1 again to avoid waste of water resources.

[0030] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
