[0022] Reference Figure 1-3 The utility model provides a gate for water conservancy projects, which mainly includes:

[0023] The main structure 100 includes a door frame 101, in which a gate plate 102 that can move up and down is installed, and the gate plate 102 includes a door body, and the left and right sides and the bottom of the door body are fixedly connected with rubber layers, and the rubber layers on the left and right sides of the door body are movably fitted with the inner walls of the door frame 101 on both sides. The rubber layer is provided to improve the sealing between the gate plate 102 and the door frame 101;

[0024] A lifting structure 200, the lifting structure 200 is fixedly connected to the top of the door frame 101 and the rear side of the gate plate 102, and is used to drive the gate plate 102 to move up and down;

[0025] The cleaning structure 300 is located at the front side of the door frame 101 and is fixedly connected to the front side of the door frame 101 , and is used to desilt the inner bottom wall of the door frame 101 .

[0026] Specifically, the lifting structure 200 includes a gantry 201 fixedly connected to the top of the door frame 101 by bolts, a driving motor 202 fixedly connected to the top of the gantry 201 by bolts, a threaded sleeve 203 and a guide sleeve 204 fixedly connected to the rear side of the gate plate 102, a first guide slide rod 205 slidably connected to the inside of the guide sleeve 204, and a screw rod 206 threadedly connected to the inside of the threaded sleeve 203, the bottom end of the screw rod 206 is spaced apart from the inner bottom wall of the door frame 101, the top end of the screw rod 206 extends to the top of the door frame 101 and is fixedly connected to the output end of the driving motor 202, the bottom end of the first guide slide rod 205 is spaced apart from the inner bottom wall of the door frame 101, and the first guide The top of the slide bar 205 is fixedly connected to the inner top wall of the door frame 101, and the screw rod 206 is rotatably connected to the top of the door frame 101 through a bearing. The advantage of such a connection is that the screw rod 206 can rotate smoothly. In addition, by setting the first guide slide bar 205, the gate 102 can be smoothly raised and lowered. When the gate 102 needs to be opened or closed, the drive motor 202 is started, and the output end of the drive motor 202 drives the screw rod 206 to rotate forward or reversely. The threaded sleeve 203 moves upward or downward along the screw rod 206 under the guidance and limiting action of the first guide slide bar 205 and the guide sleeve 204, and the threaded sleeve 203 drives the gate 102 to follow the movement, thereby realizing the automatic closing and opening of the gate 102.

[0027] Specifically, the cleaning structure 300 includes a scraper 301 located at the front side of the door frame 101, a pair of cross bars 302 fixedly connected to the side of the scraper 301 away from the door frame 101, a pair of vertical bars 303 fixedly connected to one end of the pair of cross bars 302 away from the scraper 301, a pair of second guide slide bars 304 slidably connected to the pair of vertical bars 303, a push-pull plate 305 fixedly connected between the pair of vertical bars 303, and a pair of hydraulic cylinders 306 fixedly connected to the side of the push-pull plate 305 facing the door frame 101, one end of the pair of second guide slide bars 304 are fixedly connected to the front side of the door frame 101, and the pair of hydraulic cylinders 306 are away from the push-pull plate 305. One end of the pulling plate 305 is fixedly connected to the front side of the door frame 101. The length of the scraper 301 is consistent with the internal length of the door frame 101, and is arranged corresponding to the door frame 101. The purpose of this arrangement is that the silt accumulated on the inner bottom wall of the door frame 101 can be scraped off by the scraper 301. The bottom end of the scraper 301 is a pointed structure. The advantage of this arrangement is that the silt can be scraped off better, and the bottom end and the inner bottom wall of the door frame 101 are on the same horizontal plane. The upper surface of the scraper 301 is located below the screw rod 206 and the first guide slide bar 205, so that during the movement of the scraper 301, it will not collide with the screw rod 206 and the first guide slide bar 205.

[0028] In summary, when it is necessary to clean the silt accumulated on the inner bottom wall of the door frame 101, the hydraulic cylinder 306 is started, and the hydraulic cylinder 306 immediately drives the push-pull plate 305 to move toward the door frame 101, and the push-pull plate 305 drives a pair of vertical rods 303 to move synchronously, and this pair of vertical rods 303 then moves through a pair of horizontal rods 302, so that the scraper 301 moves accordingly, and the scraper 301 enters the door frame 101 and moves on the inner bottom wall of the door frame 101. During the movement, the silt accumulated on the inner bottom wall of the door frame 101 is scraped off, thereby being able to scrape off the silt accumulated on the inner bottom wall of the door frame 101, and then when closing the gate plate 102, the problem of the gate plate 102 not closing tightly due to silt obstruction can be avoided, thereby ensuring the normal use of the gate 102, and thus not easily causing adverse effects on the overall operation of the water conservancy project.

[0029] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
