[0002] Water irrigation is a technical measure to replenish the water needed by crops. Efficient water irrigation facilities play a vital role in increasing crop yields. The water pump is the core component of water irrigation facilities.

During use, flocculent foreign matter such as water plants are easily attached to the surface of the filter screen cylinder, causing the cavities of the filter screen cylinder to be clogged, which in turn affects the suction and blockage of the water pump. Based on this, a foreign matter blocking device for the water intake pump port of a water conservancy irrigation facility is provided. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 In an embodiment of the present invention, a foreign body barrier device for a water intake pump port of a water conservancy irrigation facility includes a bracket assembly 1 consisting of a top ring plate 101, an outer protective rod 102, and a bottom plate 103. The outer protective rods 102 are provided in a plurality and distributed in an annular shape. The top ring plate 101 and the bottom plate 103 are symmetrically fixed to the upper and lower ends of the plurality of outer protective rods 102. A filter barrier assembly 2 is provided between the top ring plate 101 and the outer protective rods 102. The filter barrier assembly 2 includes a filter unit and a self-cleaning unit.

[0030] The filter unit includes a filter cartridge 203, which is used to filter smaller impurities in the water flow;

[0031] The self-cleaning unit uses the flow force of the water flow to drive the filter cartridge 203 in the filter unit to rotate, and the rotation of the filter cartridge 203 cleans the impurities adhering to the outer wall of the filter cartridge 203;

[0032] The filter unit further includes a fixed cylinder 201, a rotating shaft 202, and a through hole 205;

[0033] The fixed cylinder 201 is fixed to the bottom end of the top ring plate 101, and the filter cylinder 203 is covered on the outside of the fixed cylinder 201, and the top of the filter cylinder 203 is in contact with the bottom of the top ring plate 101;

[0034] A rotating support frame 105 is fixed to the inner side of the top ring plate 101. The rotating shaft 202 is rotatably connected to the inner side of the rotating support frame 105 and passes through the bottom end of the fixed cylinder 201. The bottom end of the filter cylinder 203 is rotatably connected to the top of the bottom plate 103. The bottom end of the filter cylinder 203 is fixedly connected to the rotating shaft 202. The rotating shaft 202 is rotatably connected to the fixed cylinder 201. The rotating shaft 202 is located on the filter cylinder 203 to provide support. The filter cylinder 203 is used to filter smaller impurities in the water flow.

[0035] A through hole 205 is provided at the bottom of the fixed cylinder 201, and the through hole 205 is used to provide a flow channel for water;

[0036] The self-cleaning unit includes blades 204 and a spiral conduit 206;

[0037] There are multiple blades 204, which are distributed circumferentially and fixed on the top of the outer side of the rotating shaft 202;

[0038] The spiral conduit 206 is fixed to the bottom of the inner wall of the fixed cylinder 201 and the bottom end of the spiral conduit 206 is aligned with the through hole 205. The top end of the spiral conduit 206 is distributed below the blade 204 and tilted toward the side of the blade 204.

[0039] The water flow transported upward through the through hole 205 and the spiral conduit 206 impacts the blades 204 to deflect them, thereby providing rotational thrust for the rotation of the rotating shaft 202 and the filter cartridge 203.

[0040] The bottom of the bottom plate 103 is provided with a straight slot that completely passes through the bottom plate 103 , and there is a height difference between the bottom of the rotating shaft 202 and the top of the bottom plate 103 ;

[0041] The rotating shaft 202 is distributed on the inner side of multiple outer protective rods 102. Brushes 106 are bonded to the outer wall of the outer protective rod 102 close to the rotating shaft 202 and the top of the bottom plate 103. The brushes 106 are used to clean the outer wall of the rotating shaft 202.

[0042] A plurality of mounting holes 104 are evenly opened on the top circumference of the top ring plate 101 . The mounting holes 104 completely penetrate to the bottom end of the top ring plate 101 , and the mounting holes 104 and the rotating support frame 105 are staggered along the circumference.

[0043] In this embodiment, it should be noted that a screw hole matching the mounting hole 104 is provided at the water inlet of the water pump. The top ring plate 101 can be tightly fixed to the water inlet of the water pump by passing a bolt through the mounting hole 104 and threading it into the screw hole and tightening it.

[0044] When pumping water, the channel formed by the filter holes on the filter cartridge 202, the through hole 205, the spiral guide tube 206, and the central hole groove of the top ring plate 101 is used to provide a channel for the suction of water. During this process, the multiple outer protective rods 102 and the bottom plate 103 can intercept larger foreign matter, and the filter cartridge 202 can intercept smaller impurities (for example, flocculent foreign matter such as water plants);

[0045] At the same time, the water flow passing through the through hole 205, the spiral duct 206 and out of the top of the spiral duct 206 can impact the blades 204, causing the blades 204 to deflect. The deflection force of multiple blades 204 will drive the rotating shaft 202 and the filter cartridge 203 to rotate. As the filter cartridge 203 rotates, relative friction occurs between the surface of the filter cartridge 203 and the brush 106. The brush 106 can perform a cleaning operation on the surface of the filter cartridge 203, thereby causing impurities adhering to the filter cartridge 202 to fall off, thereby avoiding the situation where excessive impurities adhere to the surface of the filter cartridge 202 and cause blockage, thereby further improving the stability of equipment use.

[0046] Please refer to Figures 2 to 5 A plurality of through holes 205 and spiral conduits 206 are evenly arranged around the rotating shaft 202 .

[0047] In this embodiment, by providing multiple spiral conduits 206 , the upward water flow is divided into multiple streams. The multiple streams impact the blades 204 , which can provide sufficient thrust for the rotation of the shaft 202 and the filter cartridge 203 , thereby ensuring smooth rotation of the filter cartridge 203 .

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
