[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3The utility model provides an embodiment: a trash screen for water conservancy projects, including a frame 1, a grille body 3 is slidably connected to the inner wall of one side of the frame 1, and a sub-frame 4 is slidably connected to the outer wall of the grille body 3 away from the frame 1. An adjustment mechanism 5 is provided on the grille body 3, and an auxiliary mechanism 6 is provided on the adjustment mechanism 5. The adjustment mechanism 5 includes a water outlet frame 51, and the water source filtered after the grille body 3 is blocked is discharged by setting the water outlet frame 51. The water outlet frame 51 is fixedly connected to the rear outer wall of the grille body 3. A worm 52 is rotatably connected to the inner wall of the top of the frame 1 through a bearing, and a worm wheel 54 is meshedly connected to the worm 52. By setting the worm wheel 54 and the worm 52 to cooperate with each other, the worm wheel 54 itself has a certain self-locking property when the worm 52 is not rotating, so as to prevent the worm wheel 54 from rotating. A rotating rod 55 is fixedly connected to the inner ring of the worm wheel 54, and a spur gear 56 is fixedly connected to the rotating rod 55. An auxiliary grille 57 is slidably connected to the inner wall of one side of the grille body 3, and a tooth groove 58 is provided on the outer wall of the auxiliary grille 57 on the side close to the spur gear 56.

[0025] Reference Figure 2-Figure 3 The top end of the worm 52 passes through the top outer wall of the frame 1, and the end of the worm 52 away from the frame 1 is fixedly connected with an adjusting disk 53. The adjusting disk 53 is arranged to facilitate personnel to rotate and operate, and the auxiliary grille 57 is adjusted and limited according to the height of the sewage, and the mechanical operation is reduced. At the same time, the limiter needs to be continuously powered for limit clamping, which consumes more power, and the mechanical operation also requires manual regular maintenance. The operation is relatively cumbersome, and the overall energy saving effect is not ideal. The two ends of the rotating rod 55 are rotatably connected to the inner walls of both sides of the grille body 3 through bearings, and the auxiliary grille 57 is slidably connected to the inner wall of one side of the water outlet trough frame 51. The spur gear 56 is meshed and connected to the side inner wall of the tooth groove 58. The side outer wall of the adjusting disk 53 is provided with a groove, and the top outer wall of the frame 1 is fixedly connected with a lift 2, and the inner wall of one side of the grille body 3 is fixedly connected to the output end of the lift 2. The grille body 3 is raised out of the water by setting the lift 2, and the grille body 3 that has been immersed in water for a long time is conveniently maintained.

[0026] Reference Figure 3-Figure 4 The auxiliary mechanism 6 includes a telescopic spring 61, which is fixedly connected to the inner wall of one side of the frame 1. The end of the telescopic spring 61 away from the frame 1 is fixedly connected to an adjusting plate 62. The telescopic spring 61 is provided to continuously generate thrust on the adjusting plate 62. The end of the adjusting plate 62 away from the telescopic spring 61 is fixedly connected to a sponge brush 63. The sponge brush 63 is provided to wipe and clean the dirt on the auxiliary grille 57, thereby reducing the inconvenience of manual maintenance and wiping of the auxiliary grille 57 in the narrow space inside. The outer walls on both sides of the adjusting plate 62 are slidably connected to the inner walls on both sides of the grille body 3, and the sponge brush 63 is slidably connected to the outer wall of one side of the auxiliary grille 57. The thickness of the sponge brush 63 is three centimeters.

[0027] Working principle: The worm 52 is rotated by rotating the adjusting disk 53, and the rotation of the worm 52 drives the worm wheel 54 to rotate, and the rotation of the worm wheel 54 drives the rotating rod 55 to rotate, and the rotation of the rotating rod 55 drives the spur gear 56 to rotate, and the rotation of the spur gear 56 drives the tooth groove 58 to move, and the movement of the tooth groove 58 drives the auxiliary grille 57 to move, and it is adjusted according to the sewage height of the water conservancy project. At the same time, when the auxiliary grille 57 is retracted and stored or raised and unfolded, the sponge brush 63 contacts the water inlet surface, so that the sponge brush 63 shakes and sways according to the movement of the auxiliary grille 57, and the movement is transmitted to the movement of the adjusting plate 62, and the adjusting plate 62 moves to squeeze the telescopic spring 61, so that the telescopic spring 61 continuously generates thrust on the adjusting plate 62, and then the sponge brush 63 always adheres to the surface of the auxiliary grille 57 for wiping.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
