[0030] The following will be combined with the accompanying 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.

[0031] The utility model solves the problems that most of the trash racks are fixedly installed, need to be manually rolled up or unfolded, which is troublesome, has poor applicability, and cannot cope with complex water quality environments; and most of the trash racks are single-layered, have poor ability to capture impurities in the water flow, and have low interception efficiency. Figure 1-Figure 5 The trash net layer shown includes a trash net body 3, the mesh of the trash net body 3 is diamond-shaped, and the trash net body 3 is a flexible structure; the trash net body 3 is movably installed, and the design of the diamond mesh thereon helps to increase the ventilation effect of the trash net body 3 and reduce the resistance and energy consumption generated when water flows through. The design of the diamond mesh helps to reduce the accumulation of dirt on the mesh and simplifies the cleaning process. When the trash net body 3 needs to be cleaned after long-term use, it can be quickly rinsed with equipment such as a high-pressure water gun. The diamond mesh has good self-cleaning ability and a long service life, so it can reduce the maintenance cost of the trash net. The flexible structure of the trash net body 3 is convenient for winding or unfolding. The staff can use the trash net body 3 according to the water quality without manually winding or unfolding the trash net body 3. It has strong applicability and is convenient for dealing with complex water quality environments.

[0032] The trash rack also includes a first frame body 1, a first square opening 11 is opened in the middle of the first frame body 1, and a plurality of first trash-trapping rods 12 are vertically and evenly fixedly connected in the first square opening 11, a second frame body 2 is provided on the side wall of the first frame body 1, a second square opening 21 is opened in the middle of the second frame body 2, and a plurality of second trash-trapping rods 22 are vertically and evenly fixedly connected in the second square opening 21, and the first trash-trapping rods 12 and the second trash-trapping rods 22 are arranged at intervals and staggered. Compared with a single layer, the double-layer design of the first square opening 11 and the second square opening 21 can form a denser interception net, thereby increasing the ability to capture impurities in the water flow. The staggered design of the first trash-trapping rods 12 and the second trash-trapping rods 22 can reduce the probability of impurities passing through the trash rack and improve the overall interception efficiency. At the same time, the staggered design can make the force of water flow and impurities more dispersed when passing through the trash rack, reduce the impact force on a single rod, and thus extend the service life of the trash rack.

[0033] Furthermore, the shown dirt-blocking net body 3 is arranged in the second square opening 21 on the side away from the second dirt-blocking rod 22, and the bottom of the second square opening 21 is fixedly connected to a fixing plate 5, and the side wall of the fixing plate 5 is fixedly connected to bristles 51, and the bristles 51 are in active contact with the side wall of the dirt-blocking net body 3; when the dirt-blocking net body 3 is rolled up, the dirt on the dirt-blocking net body 3 can be removed by the cooperation of the fixing plate 5 and the bristles 51, and the cooperation of the components can simply clean the dirt-blocking net body 3, reducing the workload of the staff. The cleaned dirt-blocking net body 3 can quickly resume working condition when it is unfolded again, without the need for additional pretreatment or debugging, thereby improving work efficiency.

[0034] In the present invention, a movable plate 44 is slidably provided in the middle of the second square opening 21, and the bottom surface of the movable plate 44 is fixedly connected to the top of the garbage net body 3, and the top surface of the outer wall of the second frame 2 is fixedly connected to the motor 42. The screw rod 43 is fixedly connected to the rotating shaft of the motor 42. The screw rod 43 passes through the top of the second frame 2 and is threadedly connected to the movable plate 44; when the garbage net body 3 needs to be unfolded, the motor 42 is turned on, and the rotation of the motor 42 drives the screw rod 43 to rotate. The rotation of the screw rod 43 drives the movable plate 44 to move, and the movement of the movable plate 44 drives one end of the garbage net body 3 to move upward. After the movable plate 44 moves to the top surface of the second square opening 21, the garbage net body 3 is completely unfolded. When the garbage net body 3 is unfolded, it can effectively intercept pollutants, such as those containing a large amount of floating matter, suspended matter or oil, to prevent them from further spreading to the downstream waters, protect the water body ecological environment, and reduce the harmful substances entering the water body by intercepting pollutants, thereby helping to improve the self-purification ability of the water body and accelerate the recovery and improvement of water quality.

[0035] It should be noted that a square cavity 4 is provided at the bottom of the second frame 2, and a coil spring 41 is provided inside the square cavity 4. The bottom end of the trash net body 3 passes through the bottom of the second frame 2 and is fixedly connected to the end of the coil spring 41; when it needs to be reeled in, the motor 42 rotates in the opposite direction, and the cooperation of the components moves the trash net body 3 downward. While the trash net body 3 moves, the coil spring 41 tightens and retracts the trash net body 3 into the square cavity 4. When the water quality is good, retracting the trash net body 3 can reduce the resistance of water flow, improve the smoothness of water flow, and is conducive to the natural flow and circulation of water. The trash net body 3 can be flexibly unfolded or reeled in according to the water quality, which can better adapt to the treatment needs under different water quality conditions and improve the treatment effect and efficiency.

[0036] In the present invention, a second cross bar 23 is fixedly connected to the middle of the second frame 2 in a transverse direction, and the side walls of the second cross bar 23 are fixedly connected to the side walls of the multiple second dirt-blocking rods 22. A first cross bar 13 is fixedly connected to the middle of the first frame 1 in a transverse direction, and the side walls of the first cross bar 13 are fixedly connected to the side walls of the multiple first dirt-blocking rods 12. The second cross bar 23 helps to strengthen the strength of the second dirt-blocking rods 22, making them stronger and firmer, and the first cross bar 13 helps to strengthen the strength of the first dirt-blocking rods 12, making them stronger and firmer.

[0037] It should be noted that the first dirt-trapping rod 12 and the second dirt-trapping rod 22 are respectively protruded outside the first frame 1 and the second frame 2, the first cross bar 13 is located inside the first square opening 11, and the second cross bar 23 is located inside the second square opening 21; since the first dirt-trapping rod 12 and the second dirt-trapping rod 22 protrude outside the first frame 1 and the second frame 2, it is more convenient to clean.

[0038] It should also be noted that a mechanism for cleaning the trash rack can be installed on the outside of the first trash rack 12 and the second trash rack 22. This is a mature technology in the prior art and is not limited here.

[0039] In the present invention, the side of the first frame 1 away from the first dirt-blocking rod 12 and the side of the second frame 2 away from the second dirt-blocking rod 22 are in contact with each other, and the first frame 1 and the second frame 2 are fixedly connected by multiple bolts; the first frame 1 and the second frame 2 are installed by bolts, and when disassembly and assembly are required for maintenance, it is relatively simple and convenient to use.
