Description

Technical Field

[0001] This utility model relates to the field of urban water treatment technology, specifically a rainwater runoff interception and purification treatment device. Background Technology

[0002] China's rapid social development and accelerated urbanization have led to a rapid increase in impervious urban areas and a growing problem of non-point source pollution. Prior to the 21st century, research focused primarily on point source pollution. However, with advancements in technology, improved treatment measures, and increased investment in pollution control, point source pollution has been effectively controlled, and its contribution to water pollution has declined year by year. Simultaneously, the proportion of non-point source pollution in the overall pollution load has been steadily rising, now exceeding that of point source pollution and accounting for as much as 60% of water pollution.

[0003] For example, the announcement number CN222667019U is titled "A Sponge City Rainwater Runoff Collection Device". This device includes a support leg, a box fixedly installed on the upper end of the support leg, a top plate fixedly installed on the box, the box being a hollow cavity with an opening at the top, a filter box inside the box, a filter plate detachably connected to the filter box, a funnel plate fixedly installed inside the box, and multiple springs symmetrically arranged on the filter box.

[0004] The aforementioned device lacks a purification structure during use, and rainwater containing harmful bacteria cannot be directly discharged and used, failing to meet current market demands. Therefore, we propose a rainwater runoff interception and purification treatment device to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rainwater runoff interception and purification treatment device to solve the problem mentioned in the background art that the existing devices do not have a purification structure, and rainwater with harmful bacteria cannot be directly discharged and used, thus failing to meet the current market demand.

[0008] A liquid storage tank is located at the top of the purification tank and is fixedly connected to the purification tank. An inlet pipe is provided at the top of the liquid storage tank and is fixedly connected to the liquid storage tank. A conveying pipe is connected to the surface of the liquid storage tank and is fixedly connected to the liquid storage tank. One end of the conveying pipe is connected to a pump and is fixedly connected to the purification tank. The output end of the pump is connected to a first connecting pipe located inside the purification tank. A second connecting pipe is connected to the surface of the first connecting pipe and is fixedly connected to the first connecting pipe. Multiple sets of nozzles are installed on the surface of the second connecting pipe and are fixedly connected to the second connecting pipe.

[0009] Preferably, the purification box is equipped with a filter screen inside.

[0010] Preferably, the surface of the purification box is provided with a cleaning component, and the cleaning component includes a servo motor, which is fixedly connected to the purification box. A threaded rod is installed inside the purification box, and one end of the threaded rod is connected to the output end of the servo motor.

[0011] Preferably, a bushing is connected to the end of the threaded rod, and the bushing is rotatably connected to the threaded rod. A threaded sleeve is installed on the surface of the threaded rod, and the threaded sleeve is drively connected to the threaded rod. A scraper is provided on the surface of the threaded sleeve, and a push rod is provided on one side of the scraper.

[0012] Preferably, the inner wall of the purification box is equipped with springs.

[0013] Preferably, a connecting plate is mounted on the surface of the filter screen, and a hinge is installed at the connection between the connecting plate and the filter screen.

[0014] Preferably, the surface of the filter screen has through holes, and the lower end of the filter screen is provided with a mud outlet pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting up a storage tank and an inlet pipe, allows disinfectant to enter the storage tank through the inlet pipe. By setting up a pump and a delivery pipe, starting the pump allows the disinfectant in the storage tank to be drawn and delivered to the first connecting pipe through the delivery pipe. By setting up a second connecting pipe and a nozzle, the disinfectant can enter the second connecting pipe from the first connecting pipe and be sprayed out through the nozzle, thereby disinfecting rainwater. This achieves rainwater disinfection and solves the drawback of traditional devices that do not have a purification structure and cannot directly discharge rainwater containing harmful bacteria.

[0017] 2. Through a specially designed cleaning component, the motor drives the threaded rod to rotate, which in turn drives the threaded sleeve to transmit power, thereby moving the scraper to scrape off impurities from the surface of the filter screen. This achieves automated cleaning of the filter screen surface, reduces manual labor intensity, and greatly improves the practicality of the device. Attached Figure Description
