[0027] The pile hole automatic water lifting structure includes a water lifting bucket 1, a water storage chamber 10 is opened in the water lifting bucket 1, a water inlet is opened at the bottom of the water storage chamber 10, a vertical rod 7 is slidably arranged in the water inlet hole, a stopper 14 is installed at one end of the vertical rod 7 passing through the water lifting bucket 1, a rubber cover 13 is provided on the top of the stopper 14, a hanging ring 6 is welded on the top of the vertical rod 7, a reset spring 15 is sleeved on the vertical rod 7, two support members 8 are arranged in the water storage chamber 10, the center parts of the two support members 8 are welded with the same hollow sleeve 16, the center position of the hollow sleeve 16 is opened with a through hole 9, the vertical rod 7 is slidably arranged in the through hole 9, and a plurality of rectangular holes 17 are opened in the axial direction on the hollow sleeve 16.

[0028] By setting up the structures such as the vertical pole 7, rubber cover 13 and return spring 15, the rubber cover 13 can be moved closer to or farther away from the water bucket 1 by lifting or loosening the vertical pole 7. When the water bucket 1 is placed in the pile hole, the elastic potential energy of the return spring 15 can push the rubber cover 13 away from the water bucket 1. At this time, the water inlet hole is in an open state, and water can enter the water storage chamber 10 through the water inlet hole. When the water bucket 1 is lifted from the pile hole, the rubber cover 13 can be tightly attached to the bottom surface of the water bucket 1, thereby achieving the closure of the water inlet hole, thereby preventing the water in the water storage chamber 10 from flowing out through the water inlet hole, thereby achieving the purpose of pumping water. The several rectangular holes 17 on the hollow sleeve 16 can prevent mud and sand from getting stuck in the gap between the vertical pole 7 and the through hole 9 during operation of the water bucket 1. The rectangular holes 17 can facilitate the removal of mud and sand in the gap to avoid affecting the up and down sliding of the vertical pole 7.

[0029] Specifically, in this embodiment, the support member 8 is made of three support rods spaced apart and welded along the circumferential direction. The support member 8 is welded to the inner wall of the water storage chamber 10 , and two support members 8 are spaced apart in the vertical direction in the water storage chamber 10 .

[0030] The support member 8 formed by welding three support rods can ensure the moving direction of the vertical pole 7 and prevent the vertical pole 7 from deflecting during use.

[0031] Specifically, in this embodiment, two symmetrical ear plates 4 are arranged at the edge of the top opening of the water bucket 1 , and a hanging hole 5 is opened on the ear plates 4 .

[0032] By providing the ear plates 4 and the hanging holes 5 , the water bucket 1 can be conveniently lifted and the balance of the water bucket 1 can be ensured when lifted.

[0033] Specifically, in this embodiment, a groove 12 is opened at the bottom center position of the water bucket 1, one end of the return spring 15 abuts against the inner wall of the groove 12, and the other end of the return spring 15 abuts against the rubber cover 13. The water inlet hole is opened on the top inner wall of the groove 12 and the diameter of the water inlet hole is larger than the diameter of the vertical rod 7.

[0034] Specifically, in this embodiment, a plurality of supporting legs 11 are provided at the bottom of the water bucket 1 , and the tops of the supporting legs 11 are welded to the bottom of the water bucket 1 .

[0035] The provision of the supporting legs 11 can facilitate the stability of the water bucket 1 when standing upright on the ground, and provide a certain amount of support for the water bucket 1 when placed.

[0036] Specifically, in this embodiment, a plurality of support legs 11 are arranged at intervals along the circumferential direction at the bottom of the water bucket 1 .

[0037] Specifically, in this embodiment, a plurality of water inlets 2 are provided on the water bucket 1, and a plurality of baffles 3 are hinged in the water storage chamber 10. The baffles 3 cover the water inlets 2. The baffles 3 are arc-shaped and fit the inner wall of the water storage chamber 10. A rubber sheet is arranged on the side of the baffle 3 close to the inner wall of the water storage chamber 10. The plurality of water inlets 2 are arranged on the water bucket 1 at intervals along the circumferential direction, and the baffles 3 are slightly larger than the opening size of the water inlets 2.

[0038] Through the mutual cooperation between the water inlet 2 and the baffle 3, the baffle 3 can be pushed open by water pressure during the water-drawing process of the water-drawing bucket 1, so that water enters the water storage chamber 10 through the gap between the water inlet 2 and the baffle 3. When the water-drawing process is completed and the water-drawing bucket 1 is lifted up, the baffle 3 can be pressed against the inner wall of the water storage chamber 10 by the water pressure in the water storage chamber 10, and the water inlet 2 can be closed, which can further increase the water-drawing speed of the water-drawing bucket 1 and thereby improve the working efficiency of the water-drawing bucket 1.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
