3. The anti-clogging automatic backwashing water intake system according to claim 1 or 2, wherein the first traction wire and the second traction wire are connected to the same end of the valve core; the other end of the valve core is connected to the inner wall of the horizontal connecting pipe through a movable connecting structure.
4. The anti-clogging automatic backwashing water intake system of claim 1, wherein the valve core is a spherical rubber pad.
5. The anti-clogging automatic backwashing water intake system according to claim 1 or 4, wherein a barrier net for blocking the gravity floating block is arranged at the upper end of the water inlet pipe; the aperture of the barrier net is smaller than the diameter of the gravity floating block.
6. The anti-clogging automatic backwashing water intake system of claim 1, wherein the lower end of the water outlet pipe is provided with a gate valve.
7. The anti-clogging automatic backwash water intake system according to claim 1, wherein the water blocking block is a cylindrical water blocking tank.
8. The anti-clogging automatic backwashing water intake system according to claim 1, 6 or 7, wherein the filtering anti-clogging device comprises a filter box disposed at a lower end of the water inlet pipe, fine pebbles filled in the filter box, a filter screen disposed at an upper end of the filter box, and a mesh disposed at a lower end of the filter box.
9. The anti-clogging automatic backwashing water intake system of claim 8, wherein the filtering anti-clogging device further comprises a rotary impeller disposed below the filter tank, the rotary impeller being connected to the filter tank by a bracket; the hole net is an arc-shaped hole net, and when the rotary impeller rotates, the rotary impeller is matched with the arc-shaped hole net.
10. The anti-clogging automatic backwashing water intake system of claim 8, wherein the filter tank is connected with the water inlet pipe through a thread; the funnel is also connected with the horizontal connecting pipe through threads.
