Water saving device for urban green space

Abstract

The invention discloses a water saving device for an urban green space. The water saving device comprises a filter, wherein the filter is provided with a motor cavity, a motor is fixedly installed inthe motor cavity, the inner wall of the bottom side of the motor cavity is provided with a through hole, the through hole is communicated with the interior of the filter, a sliding rod is installed inthe through hole in a sliding manner, the top end of the sliding rod is provided with a threaded groove, a threaded block is installed in the threaded groove, the top side of the threaded block is fixedly provided with a rotating shaft, the top end of the rotating shaft extends into the motor cavity and is fixedly connected with an output shaft of the motor, the bottom end of the sliding rod extends into the filter and is fixedly provided with a piston, the piston is connected with the inner wall of the filter in a sliding sealing manner, the top side of the piston is provided with an installation groove, and the bottom side of the installation groove is provided with a water permeation hole. The water in the filter is filtered by applying pressure, so that the filtering efficiency is higher, the filtering effect is better, when a filtering plate is blocked, the filtering plate can be disassembled to repair, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of water-saving equipment, in particular to a water-saving equipment used in urban green spaces. Background technique [0002] In modern cities, green space is an essential and most widely used landscape. It is also a large irrigation water user and has huge water-saving potential. Water-saving equipment for irrigating green spaces keeps the soil moist and will not cause drought due to lack of water for plants. And no matter in any weather conditions, the purpose of irrigation can be achieved, and water consumption can be saved to a greater extent. [0003] Patent No. 201520774917.7, an invention patent for water-saving equipment for urban green spaces, discloses a water-saving equipment for green spaces, including a water collection pool, a filter pool, and a water storage tank connected as one; the water collection pool is connected to the water inlet pipe and used for sedimentation The sewage sink for im...

AI Technical Summary

Problems solved by technology

The raw materials of the utility model are easy to purchase, economical and practical, easy to operate, and the purification effect is very good; the rainwater in the water storage tank is used to irrigate plants and green land through the water pump and the spray head, so that the plants can obtain good growth conditions, which can alleviate drought and reduce pollution. The city destroys the inland water cycle, thereby improving the ecological environment, but the filtration system of this equipment relies on natural permeation filtration, the filtration efficiency is low, the filtration effect is poor, and the filter layer will be clogged after long-term use, affecting the filtration effect. It is convenient to repair and replace the filter layer, but it cannot meet the needs of customers
