[0028] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0029] Embodiment 1

[0030] In order to solve the problem that the existing trash rack in the prior art is not easy to intercept fine impurities, the following solution is disclosed, specifically: Figure 1 , Figure 2 and Figure 3 , Figure 4As shown, it includes a dirt blocking frame 1, and the interior of the dirt blocking frame 1 is evenly installed with fences 2, and the fences 2 are evenly spaced inside the dirt blocking frame 1. The cross-section of the isolation block 3 is triangular, and the width of the isolation block 3 is adapted to the spacing width of the fence 2, and the interior of the fence 2 is evenly opened with through holes 15, and the through holes 15 are evenly spaced longitudinally on the fence 2. A fixed magnetic plate 17 is installed on one side of the through holes 15, and a guide plate 16 is installed on the interior of the through holes 15 on one side of the fixed magnetic plate 17. A first magnetic block 18 is installed on the side of the guide plate 16 close to the fixed magnetic plate 17. The magnetic pole of the first magnetic block 18 is the same as the magnetic pole of the fixed magnetic plate 17, and the two repel each other. The magnetic pole of the second magnetic block 19 is opposite to the magnetic pole of the fixed magnetic plate 17, and the two attract each other. The other side of the guide plate 16 An isolation block 3 is installed, and a second magnetic block 19 is installed on one side of the isolation block 3. A lifting frame 10 is sleeved on the bottom end of the outside of the dirt blocking frame 1, and cleaning blocks 21 are evenly installed inside the lifting frame 10, and the cleaning blocks 21 are located between the intervals of the partitions 2. The width of the cleaning blocks 21 is adapted to the width of the intervals between the partitions 2, and sliders 13 are installed on both sides of the lifting frame 10. Slide grooves 14 are correspondingly opened on both sides of the dirt blocking frame 1 on one side of the slider 13. Collecting tables 11 are installed on both sides of the lifting frame 10, and the edges of the collecting tables 11 are in a raised shape. Two collecting tables 11 are provided, and the two collecting tables 11 are respectively located on the water inlet and outlet sides of the dirt blocking frame 1, and drainage holes 12 are evenly opened inside the collecting tables 11, and the drainage holes 12 are evenly spaced on the collecting tables 11.

[0031] In this embodiment, when in use, a water flow channel is formed between the multiple partitions 2, so that water can flow through. Since the fixed magnetic plate 17 and the first magnetic block 18 form a repulsive force, and the fixed magnetic plate 17 is fixed in position, the guide plate 16 drives the isolation block 3 to move outward, so that the isolation block 3 moves out of the through hole 15, so that the isolation block 3 further isolates the water flow channel between the partitions 2, and the attraction between the second magnetic block 19 and the fixed magnetic plate 17 is used to make the position of the isolation block 3 more stable, so as to further intercept impurities in the water flow and improve the interception effect of smaller impurities. When impurities are intercepted, part of them will fall along the dirt blocking frame 1 to the collection platform 11, and through the rise of the lifting frame 10, the collection platform 11 can collect impurities such as garbage to facilitate salvaging from the water.

[0032] Embodiment 2

[0033] This embodiment is different from the first embodiment in that the lifting mechanism is used to directly clean and collect the impurities in the water flow channel. Figure 1 , Figure 5As shown, a lifting mechanism is provided at the top of the dirt-blocking frame 1 to drive the lifting frame 10 to move up and down. The lifting mechanism includes a supporting platform 4 installed on the top of the dirt-blocking frame 1, and a winding drum 5 is installed on the top of the supporting platform 4. A rotating shaft 7 runs through the interior of the winding drum 5, and a self-locking device 6 is provided on the outside of the rotating shaft 7. Winding ropes 8 are installed at both ends of the winding drum 5, and a fixing ring 20 is installed at the other end of the winding rope 8, and the bottom end of the fixing ring 20 is connected to one side of the top of the lifting frame 10. The winding ropes 8 are located on both sides of the dirt-blocking frame 1. At the same time, guide wheels 9 are installed on both sides of the top of the dirt-blocking frame 1, and one side of the winding rope 8 runs through the guide wheel 9. One end of the two winding ropes 8 is respectively located at the two ends of the winding drum 5, so that when the winding drum 5 rotates, the two winding ropes 8 are driven to be wound synchronously.

[0034] In this embodiment, when in use, the winding drum 5 is rotated to synchronously wind up the two winding ropes 8, so that the lifting frame 10 drives the cleaning block 21 to rise. Due to the triangular structure of the isolation block 3, the cleaning block 21 contacts and squeezes the isolation block 3, so that the isolation block 3 moves toward the inside of the through hole 15 under the squeezing effect, so that the cleaning block 21 scratches the water flow channel, so that impurities are discharged from the water flow channel to both sides and moved to the collecting table 11, so as to realize the dredging effect of the dirt blocking frame 1. Since there will be no obstructions when the water flow channel is dredged, the cleaning effect of the impurities is improved.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
