[0026] like Figure 1-5 As shown, this utility model discloses a roof drainage mesh cover for preventing rodents and cockroaches, comprising a drainage cover body 1, a sliding rail plate 2 on the outside of the drainage cover body 1, the sliding rail plate 2 being symmetrically distributed, a frame body 11 slidably connected to the side of the sliding rail plate 2, a fine mesh cover 6 embedded in the inner side of the frame body 11, the fine mesh cover 6 being circularly distributed, a float rod 10 installed on the outside of the fine mesh cover 6, a float block 9 on the outside of the float rod 10, a corner plate 8 on the outside of the corner plate 8, a connecting block 7 on the outside of the corner plate 8, a frame body 11 on the other side of the connecting block 7, a coarse mesh cover 5 embedded in the inner side of the drainage cover body 1, a reinforcing plate 12 on the top of the drainage cover body 1, a square frame 13 on the side of the reinforcing plate 12, and a counterweight top inside the square frame 13. The drain cover 16 has a coarse mesh 5 embedded inside and a fine mesh 6 slidably connected to the frame 11 inside the slide rail plate 2. A float block 9 is installed on the outside of the fine mesh 6, and a counterweight structure is installed on the top of the drain cover 1. Therefore, in the non-rainy season, the float block 9 is at the bottom of the drain cover 1, and the fine mesh 6 can isolate insects, rats, and cockroaches. When there is rain and water accumulation on the roof, the float block 9 floats up and pushes the fine mesh 6 upward, avoiding the fine mesh 6 from blocking moss and garbage on the roof, thus preventing water accumulation. The counterweight top plate 16 has a counterweight bottom plate 17 on its inner side, and the drain cover 1 has a reinforcing rib 23 on its outer side. The installation of the reinforcing rib 23 can improve the overall strength of the drain cover 1.

[0027] The slide rail plate 2 has a slide groove 4 on its side, and the frame 11 has a slider 3 on its outer side, which is embedded in the slide groove 4.

[0028] A filter screen 22 is inlaid on the inner side of the reinforcing plate 12, and a square groove 19 is opened on the inner side of the square frame 13. The counterweight top plate 16 is inlaid inside the square groove 19. Because of the square groove 19, it is convenient to install the counterweight structure inside the square frame 13.

[0029] The counterweight top plate 16 has a locking block 15 on its side and a locking groove 14 is opened inside the square groove 19. The locking block 15 is embedded inside the locking groove 14. Because of the locking block 15 and the locking groove 14, it is convenient to install the counterweight structure in the square frame 13 to play a role in limiting and fixing.

[0030] The square frame 13 has a groove 18 inside, and a counterweight base plate 17 is inlaid inside the groove 18. There are four sets of counterweight base plates 17. Because of the groove 18, it is convenient to inlay the counterweight base plate 17 inside.

[0031] A metal frame 20 is provided on the inner side of the square frame 13. A positioning groove 21 is opened inside the metal frame 20. A magnetic suction plate 24 is provided on the inner side of the counterweight top plate 16. The magnetic suction plate 24 magnetically attracts the metal frame 20. Due to the presence of the magnetic suction plate 24 and the metal frame 20, the counterweight structure can be initially and quickly installed on the inner side of the square frame 13.

[0032] The working principle of this rodent-proof and cockroach-proof roof drainage mesh cover is as follows: To prevent clogging, a coarse mesh cover 5 is embedded inside the drainage cover 1, and a sliding rail plate 2 is installed on the outside of the drainage cover 1. A slider 3 is slidably connected inside the sliding rail plate 2. A frame 11 and a fine mesh cover 6 are located on the side of the slider 3. A float block 9 and a float rod 10 are installed outside the fine mesh cover 6. A counterweight structure is installed on the top of the drainage cover 1. The drainage cover 1 is first installed directly on top of the drain outlet. The inner side of the drainage cover 1 is a coarse mesh with a 4cm aperture, and the outer side is a fine mesh with a 0.2cm aperture. When there is water accumulation on the roof, the float block 9 pushes the slider 3 on the side of the frame 11, causing it to move along the inner groove 4 of the sliding rail plate 2. This effectively prevents water accumulation on the roof and clogging of the fine mesh. When the water level drops, the fine mesh... The cover 6 descends by gravity, thus isolating rats, cockroaches, etc., and effectively prevents water accumulation on the roof during the rainy season. It can also prevent clogging of the drain outlet during use. However, during the non-rainy season, the float block 9 is located at the bottom of the drain cover 1. The fine mesh cover 6 can isolate insects, rats, and cockroaches. Furthermore, a reinforcing plate 12 and a square frame 13 are installed on the top of the drain cover 1. The reinforcing plate 12 is inlaid with a filter screen 22, and the square frame 13 has a groove 18 and a square slot 19 inside. The square slot 19 is inlaid with a counterweight top plate 16, and the groove 18 is used to inlay the counterweight bottom plate 17 at the bottom of the counterweight top plate 16. The locking block 15 on the side of the counterweight top plate 16 can be inlaid inside the slot 14 to play a limiting role. The counterweight structure installed on the top can increase the weight of the entire drain cover, thereby preventing it from tipping over.

[0033] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
