DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited. Example 1

[0021] A water conservancy irrigation anti-blocking sprinkler head, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes an outer shell 1, an outlet pipe 2, a sealing ring 13, a second filter 15, a cleaning component, a filtering component and a blocking component. There are at least three outlet pipes 2 on the upper part of the outer shell 1, a sealing ring 13 is installed in the lower part of the outer shell 1, and the inner ends of the outlet pipes 2 are all installed with second filters 15. A cleaning component is provided in the upper part of the outer shell 1, and the cleaning component can clean the outlet pipe 2. A filtering component is provided in the upper part of the outer shell 1, and the filtering component can filter impurities in the water. A blocking component is provided in the upper part of the outer shell 1, and the blocking component can block the outlet pipe 2.

[0022] When using the device, the staff connects the lower end of the device to the water pipe, and the sealing ring 13 can ensure the sealing of the connection. After the connection, the water in the water pipe enters the outer shell 1, and the filter component performs preliminary filtration. The filtered water passes through the second filter screen 15 for secondary filtration, and then enters the water outlet pipe 2 for spraying. When the water in the outer shell 1 flows, the cleaning component can clean the water outlet pipe 2 and the second filter screen 15 to prevent impurities from clogging the second filter screen 15. When the irrigation is completed, the staff plugs in the blocking component to block the water outlet pipe 2 to stop irrigation. Example 2

[0023] On the basis of Example 1, Figure 2 As shown, the cleaning assembly includes a fixed frame 3, a brush 4, a rotating shaft 5 and a rotating blade 6. The fixed frame 3 is bolted to the upper position inside the outer shell 1. The middle part of the fixed frame 3 is connected to the rotating shaft 5 through a bearing. A cross plate is welded to the lower part of the rotating shaft 5. A brush 4 for cleaning impurities is welded to the upper part of the rotating shaft 5. The brush 4 is in contact with the inner wall of the outer shell 1. The lower part of the rotating shaft 5 is keyed to the rotating blade 6.

[0024] When the device is used, water flow impacting the rotating blades 6 drives the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the brush 4 to rotate to clean the inner end of the water outlet pipe 2 and the second filter screen 15 to prevent impurities from staying on the second filter screen 15 and causing blockage.

[0025] like Figure 2 and Figure 3 As shown, the filter assembly includes a first filter screen 7, a guide rail 8, a spring 9 and a collision block 10. Two guide rails 8 are bolted to the upper inner part of the outer shell 1. The first filter screen 7 is slidably connected between the two guide rails 8. The springs 9 are connected between the first filter screen 7 and the guide rail 8. The collision block 10 is welded at an eccentric position of the first filter screen 7, and the cross plate rotates to contact the collision block 10.

[0026] When the device is used, water enters the housing 1 and is initially filtered through the first filter screen 7. When the rotating shaft 5 rotates, the cross plate will rotate together, thereby continuously squeezing the impact block 10 to move downward. Under the action of the spring 9, the first filter screen 7 will swing up and down to prevent impurities from accumulating on the first filter screen 7.

[0027] like Figure 1 As shown, the blocking assembly includes a rotating ring 11, a baffle 12 and an anti-sliding block 14. The upper part of the outer shell 1 is rotatably connected to the rotating ring 11, and at least three baffles 12 for blocking the water outlet pipe 2 are connected to the rotating ring 11. At least four anti-sliding blocks 14 are connected to the rotating ring 11.

[0028] When irrigation is completed, the staff controls the rotating ring 11 to rotate. Under the action of the anti-slip block 14, the staff's hands can be prevented from slipping. The rotation of the rotating ring 11 drives the baffle 12 to rotate. After the baffle 12 rotates, it can block the water outlet pipe 2, thereby stopping irrigation.

[0029] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
