Description

Technical Field

[0002] Currently, some parks are equipped with vegetation irrigation devices to replace manual irrigation, saving time and effort.

[0003] For example, CN 216567496 U discloses a water-saving intelligent irrigation device for pocket parks, which includes an irrigation body buried underground. The irrigation body contains a spraying device connected to a water storage tank, which is connected to a water inlet device. The spraying device has a water pump connected to the water storage tank, and a first outlet pipe connected to the end of the water pump furthest from the water storage tank. The first outlet pipe extends out of the irrigation body and connects to a spray head that can rotate 360°. A lower liquid level sensor is installed at the bottom of the water storage tank, and an upper liquid level sensor is installed at the top. A water inlet is located at the top of the water storage tank, and a mesh-like perforated sealing cover is installed on the inlet. The water inlet device has a solenoid valve, one end of which is connected to the water inlet pipe, and the other end is connected to a second outlet pipe. The irrigation body also has a pressure sensor and a temperature sensor. However, the following problems exist during its use: the mesh-like perforated sealing cover is close to the ground, allowing a lot of soil impurities to enter with rainwater and accumulate in the water storage tank, making them difficult to remove.

[0012] The beneficial effects of this utility model are:

[0013] 1. In rainy weather, rainwater passes through a double filter of a filter screen and a filter mesh before entering the water receiving cylinder. It then passes through another filter layer into the guide pipe and finally into the storage tank for water storage. After a set time, the inclined screw conveyor is activated to transport the sludge deposited at the bottom of the water receiving cylinder to the outside of the storage tank. This prevents sludge buildup in the storage tank, provides a regular cleaning function, saves time and effort, and ensures the water storage capacity of the tank.

The upper end of the water receiving cylinder 9 is a water receiving hopper 7 that is wider at the top and narrower at the bottom. An expanding cylinder 6 is fixed to the upper part of the water receiving hopper 7. The upper edge of the expanding cylinder 6 extends out of the upper surface of the water storage tank 3 and a filter screen is fixed thereon. In this embodiment, the filter screen includes a water inlet cylinder 12 supported in the expanding cylinder 6, a filter grid plate 13 located at the upper end of the water inlet cylinder 12, a filter screen 14 located at the lower end of the water inlet cylinder 12, and a water inlet elbow 5 located at the center of the filter grid plate 13.
