[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 A hydraulic gate lifting device shown includes:

[0026] The frame 1 has limit slots 2 on both sides thereof, and a slide bar 3 is fixedly connected to the frame 1;

[0027] The lifting assembly includes a motor 4 fixedly connected to the top of the frame 1, a bidirectional screw rod 5 fixedly connected to the bottom end of the motor 4, and two moving blocks 6 are externally threadedly connected to the bidirectional screw rod 5. A filter screen plate 7 is fixedly connected to the front end of the upper moving block 6, and a gate 8 is fixedly connected to the rear end of the lower moving block 6;

[0028] The cleaning assembly includes a fixing seat 9 fixedly connected to the top of the frame 1, an electric push rod 10 is connected inside the fixing seat 9, and a connecting rod 11 is fixedly connected to the telescopic end of the electric push rod 10. By setting the connecting rod 11, the connecting rod 11 can support the rotating shaft 12 to prevent the rotating shaft 12 from deviating and falling during rotation, thereby ensuring the stable rotation of the rotating shaft 12;

[0029] The left end of the connecting rod 11 is rotatably connected to a rotating shaft 12 , and a cleaning brush 13 is fixedly connected to the outside of the rotating shaft 12 .

[0030] A gear 14 is fixedly connected to the outside of the rotating shaft 12, and a rack 15 is fixedly connected to the front side of the frame 1. The gear 14 meshes with the rack 15, and the gate 8 is slidably connected in the limiting groove 2. By setting the limiting groove 2, the limiting groove 2 and the gate 8 cooperate with each other to avoid the gate 8 from being offset and misaligned during the lifting process, thereby ensuring the stable movement of the gate 8;

[0031] A scraper 16 is connected inside the connecting rod 11, and the scraper 16 abuts against the outside of the filter screen plate 7. The right end of the rear side of the filter screen plate 7 is fixedly connected to a limit block 17. By setting the limit block 17, the limit block 17 cooperates with the slide bar 3 to avoid the filter screen plate 7 from deflecting during the lifting process, thereby ensuring the stable use of the filter screen plate 7.

[0032] The slide rod 3 is slidably connected in the limit block 17, and the bottom end of the bidirectional screw rod 5 is rotatably connected with a fixed block 18. By setting the fixed block 18, the fixed block 18 can support the bidirectional screw rod 5 to avoid the bidirectional screw rod 5 from being offset and stuck during rotation, thereby ensuring the stable rotation of the bidirectional screw rod 5;

[0033] The left side of the fixed block 18 is fixedly connected in the frame 1 , the bottom end of the slide bar 3 is fixedly connected with a connecting block 19 , and the right side of the connecting block 19 is fixedly connected in the frame 1 .

[0034] The working principle of the utility model is:

[0035] When using the device, when it is necessary to open the gate 8, start the motor 4, and the motor 4 drives the bidirectional screw rod 5 to rotate, so that the moving block 6 located at the bottom drives the gate 8 to rise in the limit groove 2, and the moving block 6 located at the top drives the filter plate 7 and the limit block 17 to slide toward each other outside the slide rod 3, so as to collect and block the garbage floating in the river. When the filter plate 7 drives the garbage to rise, the electric push rod 10 can be started, and the electric push rod 10 pushes the connecting rod 11 to move back and forth while driving the rotating shaft 12, the cleaning brush 13 and the gear 14 to move synchronously. The gear 14 can rotate continuously under the action of the rack 15, so as to clean the filter plate 7, and the scraper 16 can further scrape off the garbage so that it can fall into the external collection box, which is convenient for subsequent further processing.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
